PRELIMINARY—SUBJECT TO COMPLETION, DATED SEPTEMBER 5, 2018

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Shareholder of Skagit Bancorp, Inc.:

          On July 25, 2018, Skagit Bancorp, Inc., or "Skagit," and Banner Corporation, or "Banner," entered into an Agreement and Plan of Merger, which we refer to as the "merger agreement," under which Skagit will merge with and into Banner, which we refer to as the "merger." Immediately following the completion of the merger, Skagit Bank, the wholly owned subsidiary of Skagit, will merge with and into Banner Bank, a wholly owned bank subsidiary of Banner, with Banner Bank continuing as the surviving bank (which we refer to as the "bank merger").

          In the merger, each share of Skagit common stock will be converted into the right to receive 5.6664 shares (which we refer to as the "exchange ratio") of Banner common stock, subject to adjustment as provided in the merger agreement (which we refer to as the "merger consideration"). The merger consideration may be reduced, via a downward adjustment to the exchange ratio, on a dollar-for-dollar basis if Skagit's shareholders' equity, measured as of the month-end prior to the closing (or, if the closing is expected to occur in the first eight days of a month, the preceding month-end) and subject to certain adjustments (which we refer to as the "adjusted shareholders' equity") is less than $80 million, as described in this proxy statement/prospectus. If adjusted shareholders' equity is equal to or exceeds $80 million, there will be no adjustment to the exchange ratio, and Skagit may declare and pay a special cash dividend to shareholders immediately prior to the closing in an amount not to exceed such excess.

          Based on the closing price of $61.60 per share of Banner common stock on July 25, 2018, the last trading day before the announcement of the merger agreement, the merger consideration represented approximately $349.05 for each share of Skagit common stock and aggregate consideration of approximately $191.1 million, subject to adjustment as provided in the merger agreement. Based on Banner's closing price of $64.96 per share on September 4, 2018, the last practicable trading day before the date of the enclosed proxy statement/prospectus, and the number of shares of Skagit common stock outstanding as of such date, the merger consideration represented approximately $368.09 for each share of Skagit common stock and aggregate consideration of approximately $201.6 million, subject to adjustment as provided in the merger agreement. We encourage you to obtain current market quotations for the common stock of Banner before you vote. Banner common stock is currently quoted on the NASDAQ Global Select Market (which we refer to as the "NASDAQ") under the symbol "BANR."

          The number of shares of Banner common stock to be delivered to holders of shares of Skagit common stock upon completion of the merger is approximately 3,083,978 shares, based on the number of shares of Skagit common stock outstanding as of September 4, 2018.

          The merger cannot be completed unless Skagit shareholders holding at least two-thirds of the outstanding shares of Skagit common stock as of the close of business on September 4, 2018, the record date for the special meeting, vote in favor of the approval of the merger agreement at the special meeting.

          The special meeting of Skagit shareholders will be held on October 15, 2018, at 6:00 p.m., Pacific Time, at McIntyre Hall, located at 2501 E. College Way, Mount Vernon, Washington 98273.

          Your vote is very important, regardless of the number of shares of Skagit common stock you own. To ensure your representation at the special meeting, please take time to vote by following the instructions contained in this proxy statement/prospectus and on your proxy card. Please vote promptly whether or not you expect to attend the special meeting. Submitting a proxy now will not prevent you from being able to vote in person at the special meeting.

          Skagit's board of directors unanimously recommends that Skagit shareholders vote "FOR" the proposal to approve the merger agreement and "FOR" the other matters to be considered at the special meeting.

          This proxy statement/prospectus describes the special meeting of Skagit shareholders, the merger, the documents relating to the merger and other related matters. Please read carefully the entire proxy statement/prospectus, including the section entitled "Risk Factors" beginning on page 34, for a discussion of the risks relating to the proposed merger, and the Annexes and documents incorporated by reference into the proxy statement/prospectus.

          If you have any questions regarding the accompanying proxy statement/prospectus, you may contact Nancy K. Galbreath, Executive Assistant to the CEO, Skagit Bancorp, Inc., at 301 East Fairhaven Avenue, Burlington, Washington 98233, or by telephone at (360) 755-0411.

Sincerely,

Cheryl R. Bishop

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

Dear Shareholder of Skagit Bancorp, Inc.:

        You are cordially invited to attend a special meeting of Skagit shareholders. The special meeting will be held on October 15, 2018, at 6:00 p.m., Pacific Time, at McIntyre Hall, located at 2501 E. College Way, Mount Vernon, Washington 98273, to consider and vote upon the following matters:

1.

a proposal to approve the Agreement and Plan of Merger, dated as of July 25, 2018, as it may be amended from time to time, by and between Banner Corporation, a Washington corporation, and Skagit Bancorp, Inc., a Washington corporation; and



2.

a proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

        The record date for the special meeting is September 4, 2018. Only shareholders of record as of the close of business on September 4, 2018 are entitled to notice of, and to vote at, the special meeting. All shareholders of record as of that date are cordially invited to attend the special meeting in person. The approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Skagit common stock entitled to vote at the special meeting. The approval of adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement requires the affirmative vote of a majority of the shares represented at the meeting and entitled to vote.

        Skagit's board of directors has unanimously adopted and approved the merger agreement and the transactions contemplated thereby, including the merger, has determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to and in the best interests of Skagit and its shareholders, and unanimously recommends that Skagit shareholders vote "FOR" the proposal to approve the merger agreement and "FOR" the proposal to approve adjournment of the special meeting if there are insufficient votes at the time of the special meeting to approve the merger agreement. In considering the recommendation of the board of directors of Skagit, you should be aware that certain directors and executive officers of Skagit have interests in the merger that may be different from, or in addition to, the interests of Skagit shareholders generally. See the section entitled "The Merger—Interests of Directors and Executive Officers of Skagit in the Merger" beginning on page 68 of the accompanying proxy statement/prospectus.

        Skagit shareholders have a right to dissent from the merger and obtain payment of the fair value of their Skagit shares under Washington law, but only if they perfect their dissenters' rights and comply with the application provisions of Washington law. A copy of the applicable Washington statutory provisions regarding dissenters' rights is attached as Annex C to the accompanying proxy statement/prospectus. For details on your dissenters' rights and applicable procedures, please see the discussion "Dissenters' Rights" beginning on page 74.

        Your vote is very important, regardless of the number of shares of Skagit common stock that you own. We cannot complete the merger unless Skagit shareholders approve the merger agreement.

        Even if you plan to attend the special meeting in person, Skagit requests that you complete, sign, date and return, as promptly as possible, the enclosed proxy card in the accompanying prepaid reply envelope prior to the special meeting to ensure that your shares of Skagit common stock will be represented at the special meeting if you are unable to attend. If you hold your shares in "street name" through a bank, brokerage firm or other nominee, you should follow the procedures provided by your bank, brokerage firm or other nominee to vote your shares. If you fail to submit a proxy or to attend the special meeting and vote in person or do not provide your bank, brokerage firm or other nominee with instructions as to how to vote your shares, as applicable, your shares of Skagit common stock will not be counted for purposes of determining whether a quorum is present at the special meeting and will have the same effect as a vote "against" the approval of the merger agreement.

        WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING, PLEASE COMPLETE, DATE, SIGN AND RETURN, AS PROMPTLY AS POSSIBLE, THE ENCLOSED PROXY CARD IN THE ACCOMPANYING PREPAID REPLY ENVELOPE.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

        The following questions and answers are intended to briefly address some commonly asked questions regarding the merger, the merger agreement and the special meeting. We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the annexes to, and the documents incorporated by reference in, this document.

Q:

Why am I receiving this proxy statement/prospectus and proxy card?

A:

Skagit has agreed to be acquired by Banner under the terms of the merger agreement that are described in this proxy statement/prospectus. Immediately following the merger, Skagit Bank, Skagit's banking subsidiary, will merge with and into Banner's banking subsidiary, Banner Bank, with Banner Bank being the surviving entity, which transaction is referred to as the "bank merger." In order for us to complete the transactions contemplated by the merger agreement, we need, among other things, certain approvals and/or waivers from the Board of Governors of the Federal Reserve System (which we refer to as the "Federal Reserve Board"), the Federal Deposit Insurance Corporation (which we refer to as the "FDIC") and the Washington State Department of Financial Institutions, Division of Banks (which we refer to as the "DFI"), as described in the section entitled "The Merger—Regulatory Approvals" beginning on page 72 of this proxy statement/prospectus, and the approval of the merger agreement by Skagit shareholders.

This proxy statement/prospectus includes important information about the merger, the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus, and the special meeting. Skagit shareholders should read this information carefully and in its entirety. The enclosed voting materials allow shareholders to vote their shares without attending the special meeting in person.

Q:

What am I being asked to vote on at the special meeting?

A:

Skagit is holding the special meeting to ask its shareholders to consider and vote upon a proposal to approve the merger agreement. Skagit shareholders are also being asked to consider and vote upon a proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

Q:

Does my vote matter?

A:

Yes. The merger cannot be completed unless the merger agreement is approved by the Skagit shareholders. The Skagit board of directors, which we refer to as the "Skagit board," unanimously recommends that shareholders vote "FOR" the proposal to approve the merger agreement.

Q:

What is the vote required to approve each proposal at the special meeting?

A:

The approval of the merger agreement requires the affirmative vote of holders of two-thirds of the outstanding shares of Skagit common stock entitled to vote at the special meeting. If you fail to submit a proxy or vote in person at the special meeting, or vote to abstain, or you do not provide your bank, brokerage firm or other nominee with voting instructions, as applicable, this will have the same effect as a vote "AGAINST" the approval of the merger agreement.

The approval of adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement requires the affirmative vote of the majority of the shares represented at the

Table of Contents

meeting and entitled to vote. If your shares of Skagit common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, your vote will be considered "AGAINST" the proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. If you fail to submit a proxy or vote in person at the special meeting or if your shares of Skagit common stock are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares of Skagit common stock, your shares of Skagit common stock will not be voted, and this will not have an effect on the vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

See the section entitled "Information About the Special Meeting—Record Date and Quorum" beginning on page 40 of this proxy statement/prospectus.

Q:

How does the Skagit board recommend that I vote at the special meeting?

A:

The Skagit board unanimously recommends that Skagit shareholders vote "FOR" the proposal to approve the merger agreement and "FOR" the proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. See the section entitled "The Merger—Skagit's Reasons for the Merger; Recommendation of the Skagit Board of Directors" beginning on page 52 of this proxy statement/prospectus.

Q:

Am I entitled to dissenters' or appraisal rights?

A:

Under Washington law, holders of record of Skagit common stock at the record date who do not vote in favor of the approval of the merger agreement have the right to dissent from the merger and obtain payment for the fair value of their shares if the merger is completed, but only if they follow the procedures and satisfy the conditions prescribed by Chapter 23B.13 of the Washington Business Corporation Act, which we refer to as the "WBCA." A copy of the applicable statutes regarding dissenters' rights is attached as Annex C to this proxy statement/prospectus. For an explanation of your dissenters' rights and how to exercise them, please see the discussion under the heading "The Merger—Dissenters' Rights."

Q:

What will I receive if the merger is completed?

A:

If the merger is completed, each share of Skagit common stock outstanding immediately prior to the effective time of the merger, except for certain shares held by Banner or Skagit (in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity or as a result of debts previously contracted) or by a Skagit shareholder who properly exercises dissenters' right when and in the manner required under Chapter 23B.13 of the WBCA, will be converted into the right to receive 5.6664 shares of Banner common stock, subject to adjustment as provided in the merger agreement, which we refer to as the "merger consideration." The merger consideration may be reduced, via a downward adjustment to the exchange ratio, on a dollar-for-dollar basis if Skagit's shareholders' equity, measured as of the month-end prior to the closing (or, if the closing is expected to occur in the first eight days of a month, the preceding month-end) and subject to certain adjustments (which we refer to as "adjusted shareholders' equity") is less than $80 million, as described in "The Merger Agreement—Merger Consideration—Potential Adjustment to Exchange Ratio." If adjusted shareholders' equity is equal to or exceeds $80 million, there will be no adjustment to the exchange ratio, and Skagit may declare and pay a special cash dividend to shareholders immediately prior to the closing in an amount not to exceed such excess. Throughout this proxy statement/prospectus,

2

---

Table of Contents

unless specifically stated otherwise, references to the "merger consideration" and the "exchange ratio," and all calculations related thereto, assume an exchange ratio of 5.6664, without any adjustment.

Banner will not issue any fractional shares of Banner common stock in the merger. In lieu of the issuance of any such fractional share, Banner will pay to each Skagit shareholder who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average closing price of Banner common stock on the NASDAQ for the consecutive period of the five (5) full trading days immediately preceding (but not including) the date that is the second (2nd) business day prior to the closing date, which we refer to as the "Banner average closing price," by (ii) the fraction of a share (after taking into account all shares of Skagit common stock held by such holder immediately prior to the effective time of the merger and rounded to the nearest one-thousandth when expressed in decimal form) of Banner common stock to which such holder would otherwise be entitled to receive pursuant to the merger agreement.

See the section entitled "The Merger Agreement—Merger Consideration" beginning on page 77 of this proxy statement/prospectus.

Q:

What is the exchange ratio?

A:

The exchange ratio is used to determine the number of shares of Banner common stock that Skagit shareholders will be entitled to receive for each share of Skagit common stock they hold. The exchange ratio is 5.6664, as set forth in the merger agreement, subject to adjustment as provided in the merger agreement as described above.

Q:

What is the value of the per share merger consideration?

A:

The value of the merger consideration will fluctuate as the market price of Banner common stock fluctuates before the completion of the merger. This price will not be known at the time of the special meeting and may be more or less than the current price of Banner common stock or the price of Banner common stock at the time of the special meeting. Based on the closing price of $61.60 per share of Banner common stock on July 25, 2018, the last trading day before the announcement of the merger agreement, the value of the merger consideration was approximately $349.05 per share of Skagit common stock. Based on Banner's closing price of $64.96 per share on September 4, 2018, the last practicable trading day before the date of the enclosed proxy statement/prospectus, the value of the merger consideration was approximately $368.09 per share of Skagit common stock. We urge you to obtain current market quotations for shares of Banner common stock. See the section entitled "The Merger Agreement—Merger Consideration" beginning on page 77.

Q:

What will happen to Skagit as a result of the merger?

A:

If the merger is completed, Skagit will be merged with and into Banner, with Banner surviving the merger as the surviving corporation.

Q:

What equity stake will Skagit shareholders hold in Banner immediately following the merger?

A:

Based on the number of issued and outstanding shares of Banner common stock and Skagit common stock as of September 4, 2018, we expect that Skagit shareholders as of immediately prior to the closing of the merger will hold, in the aggregate, approximately 8.7% of the issued and outstanding shares of Banner common stock immediately following the closing of the merger (without giving effect to any shares of Banner common stock held by Skagit shareholders prior to the merger or any potential adjustment to the exchange ratio).

Table of Contents

Q:

When do you expect the merger to be completed?

A:

Subject to the satisfaction or waiver of the closing conditions described under the section entitled, "The Merger Agreement—Conditions to Completion of the Merger" beginning on page 94 of this proxy statement/prospectus, including the approval of the merger agreement by Skagit shareholders at the special meeting, Banner and Skagit expect that the merger will be completed in the fourth quarter of 2018. However, it is possible that factors outside the control of both companies, including whether or when the required regulatory approvals will be received, could result in the merger being completed at a different time or not at all.

Q:

What are the material U.S. federal income tax consequences of the merger to Skagit shareholders?

A:

The merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (which we refer to as the "Code"), and it is a condition to the respective obligations of Skagit and Banner to complete the merger that each of Skagit and Banner receives an opinion of counsel to that effect. Accordingly, holders of Skagit common stock are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of shares of Skagit common stock for shares of Banner common stock in the merger, except with respect to any cash received instead of fractional shares of Banner common stock.

For further information, please refer to "Material U.S. Federal Income Tax Consequences" beginning on page 100. The U.S. federal income tax consequences described above may not apply to all holders of Skagit common stock. The particular tax consequences to a holder of Skagit common stock will depend on his or her individual situation. Accordingly, holders of Skagit common stock should consult their tax advisors for a full understanding of the particular U.S. federal, state, local, foreign or other tax consequences of the merger to them.

Q:

Are there any risks that I should consider in deciding whether to vote for the approval of the merger agreement?

A:

Yes. You should read and carefully consider the risk factors set forth in the section entitled "Risk Factors" beginning on page 34 of this proxy statement/prospectus. You also should read and carefully consider the risk factors of Banner contained in the documents that are incorporated by reference into this proxy statement/prospectus. See the section entitled "Where You Can Find More Information" beginning on page 120 of this proxy statement/prospectus.

Q:

Who can vote at the special meeting?

A:

All holders of record of Skagit common stock as of the close of business on September 4, 2018, the record date for the special meeting, which we refer to as the "record date," are entitled to receive notice of, and to vote at, the special meeting, or any postponement or adjournment of the special meeting scheduled in accordance with Washington law.

Q:

When and where is the special meeting?

A:

The special meeting will be held on October 15, 2018, at 6:00 p.m., Pacific Time, at McIntyre Hall, located at 2501 E. College Way, Mount Vernon, Washington 98273. For additional information about the special meeting, see the section entitled "Information About the Special Meeting" beginning on page 40 of this proxy statement/prospectus.

Q:

How will I receive the merger consideration to which I am entitled?

A:

After the effective time of the merger, each record holder, as of immediately prior to the effective time of the merger, of shares of Skagit common stock that are converted into the right to receive the merger consideration will receive a letter of transmittal and instructions from the exchange agent describing the procedures for surrendering their certificate or certificates representing shares of Skagit common stock (which we refer to as a "Skagit certificate," which is deemed to include reference to book-entry accounts relating to the ownership of shares of Skagit common stock).

When you properly surrender your Skagit certificates, and return the letter of transmittal duly executed and completed in accordance with its instructions, the exchange agent will promptly cancel the surrendered stock certificates and deliver to you a notice specifying, among other things, the number of shares of Banner common stock, which will be solely in uncertificated book-entry form credited to the account of the holder of record, and cash for fractional shares, if any, to which you are entitled under the merger agreement.

More information on the documentation Skagit shareholders are required to deliver to the exchange agent may be found under the captions "The Merger Agreement—Exchange and Payment Procedures" beginning on page 81 of this proxy statement/prospectus.

Q:

Will my shares of Banner common stock acquired in the merger receive a dividend?

A:

After the closing of the merger, as a holder of Banner common stock, you will receive the same dividends on shares of Banner common stock that all other holders of shares of Banner common stock will receive with any dividend record date that occurs after the merger is completed.

Until surrendering Skagit stock certificates or book entry shares in accordance with the instructions provided, former Skagit shareholders who hold Skagit stock certificates or book entry shares will not be entitled to be paid dividends with a record date after the closing of the merger that is otherwise payable on the shares of Banner common stock into which their shares of Skagit common stock are exchangeable.

Any such payment of dividends by Banner would require approval by the Banner board of directors and the Banner board of directors may change its dividend policy at any time. See "Comparative Per Share Market Price and Dividend Information" beginning on page 29 for a comparison of the historical dividend practices of the two companies.

Q:

Do any of Skagit's directors or executive officers have interests in the merger that may differ from those of Skagit shareholders?

A:

Skagit's directors and executive officers have interests in the merger that may be different from, or in addition to, those of Skagit shareholders generally. The Skagit board of directors was aware of and considered these interests, among other matters, in evaluating the merger agreement and the merger, and in recommending that Skagit shareholders approve the merger agreement. For a description of these interests, refer to the section entitled "The Merger—Interests of Directors and Executive Officers of Skagit in the Merger" beginning on page 68 of this proxy statement/prospectus.

Q:

What is the difference between holding shares as a shareholder of record and as a beneficial owner?

A:

If your shares of Skagit common stock are registered directly in your name with the transfer agent of Skagit, Skagit Bank, you are considered the shareholder of record with respect to those shares. As the shareholder of record, you have the right to vote, or to grant a proxy for your vote directly to Skagit or to a third party to vote at the special meeting.

Table of Contents

If your shares are held by a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares held in "street name," and your bank, brokerage firm or other nominee is considered the shareholder of record with respect to those shares. Your bank, brokerage firm or other nominee will send you, as the beneficial owner, a package describing the procedure for voting your shares. You should follow the instructions provided by them to vote your shares. You are invited to attend the special meeting; however, you may not vote these shares in person at the special meeting unless you obtain a "legal proxy" from your bank, brokerage firm or other nominee that holds your shares, giving you the right to vote the shares at the special meeting.

Q:

If my shares of Skagit common stock are held in "street name" by my bank, brokerage firm or other nominee, will my bank, brokerage firm or other nominee automatically vote those shares for me?

A:

Your bank, brokerage firm or other nominee will only be permitted to vote your shares of Skagit common stock if you instruct your bank, brokerage firm or other nominee how to vote. You should follow the procedures provided by your bank, brokerage firm or other nominee regarding the voting of your shares of Skagit common stock. Banks, brokerage firms and other nominees who hold shares of Skagit common stock in "street name" for their customers typically have authority to vote on "routine" proposals when they have not received voting instructions from beneficial owners. However, banks, brokerage firms and other nominees are precluded from exercising their voting discretion with respect to non-routine matters, such as the approval of the merger agreement and adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. As a result, absent specific voting instructions from the beneficial owner of such shares, banks, brokerage firms and other nominees are not empowered to vote such shares. A so-called "broker non-vote" results when banks, brokerage firms and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares. The effect of not instructing your broker how you wish your shares to be voted will be the same as a vote "against" the approval of the merger agreement and will have no effect on the vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

Q:

How many votes do I have?

A:

Each Skagit shareholder is entitled to one vote for each share of Skagit common stock held of record as of the record date. As of the close of business on the record date, there were 544,257 outstanding shares of Skagit common stock entitled to vote at the special meeting.

Q:

What constitutes a quorum for the special meeting?

A:

The presence, in person or represented by proxy, of shareholders who hold a majority of the shares entitled to vote at the special meeting constitutes a quorum for the purposes of the special meeting. Abstentions and broker non-votes, if any, are counted as present for purposes of establishing a quorum.

If a quorum is not present, a majority of the shares represented at the special meeting may adjourn the special meeting.

Q:

What do I need to do now?

A:

Even if you plan to attend the special meeting in person, after carefully reading and considering the information contained in this proxy statement/prospectus, please vote promptly to ensure that your shares are represented at the special meeting.

Q:

How do I vote?

A:

Shareholder of Record.    If you are a shareholder of record, you may have your shares of Skagit common stock voted on the matters to be presented at the special meeting in the following ways:

•

by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope; or

•

in person—you may attend the special meeting and cast your vote there.

Beneficial Owner.    If you are a beneficial owner, please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you. Please note that if you are a beneficial owner and wish to vote in person at the special meeting, you must obtain a legal proxy from your bank, brokerage firm or other nominee.

Participant in Skagit 401(k) Plan.    The Skagit Bank Employees' Retirement Plan, which holds 4,764 shares of Skagit common stock as of the date of this proxy statement/prospectus, provides that the plan's two trustees are authorized to exercise voting rights associated with such shares. It is anticipated that the plan's trustees, who are also Skagit directors, will vote the shares held by the plan in favor of the matters to be presented at the special meeting, including the merger.

Q:

Can I attend the special meeting and vote in person?

A:

Yes. All Skagit shareholders are invited to attend the special meeting. Shareholders of record of Skagit common stock as of the record date for the special meeting can vote in person at the special meeting.

If you plan to attend the special meeting, you must hold your shares in your own name and bring evidence of your stock ownership, such as your most recent account statement, or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of government-issued personal photo identification with you in order to be admitted to the meeting.

If your shares of Skagit are held in "street name," then you are not the shareholder of record. In order for you to vote the shares that you beneficially own and that are held in "street name" in person at the special meeting, you must bring a legal proxy, executed in your favor, from the bank, brokerage firm or other nominee that was the record holder of your shares held in "street name" as of the record date (i) confirming that you were the beneficial owner of those shares as of the record date, (ii) stating the number of shares of which you were the beneficial owner that were held for your benefit at that time by that bank, brokerage firm or other nominee, and (iii) appointing you as the record holder's proxy to vote the shares covered by that proxy at the special meeting.

Whether or not you intend to be present at the special meeting, you are urged to sign, date, and return your proxy card promptly. If you are then present and wish to vote your shares in person, your original proxy may be revoked by requesting a revocation of your submitted proxy and voting by ballot at the special meeting.

Table of Contents

Q:

How can I change or revoke my vote?

A:

You have the right to revoke a proxy at any time before it is exercised, and your last vote is the vote that will be counted. If you are a Skagit shareholder of record, you can write to Nancy K. Galbreath, Executive Assistant to the CEO, Skagit Bancorp, Inc., at 301 East Fairhaven Avenue, Burlington, Washington 98233, stating that you wish to revoke your proxy and requesting another proxy card. If you hold your shares through a broker, bank or other nominee, you can revoke your proxy by contacting the broker, bank or other nominee and asking for a new proxy card. If you attend the meeting, you must request a revocation of your submitted proxy and vote by ballot to revoke your proxy. Your attendance alone at the special meeting will not of itself constitute a revocation of your proxy.

Q:

If a shareholder gives a proxy, how are the shares of Skagit common stock voted?

A:

Regardless of the method you choose to vote, the individuals named on the enclosed proxy card will vote your shares of Skagit common stock in the way that you indicate. When completing the proxy card, you may specify whether your shares of Skagit common stock should be voted "for" or "against," or whether your shares should "abstain" from voting on, all, some or none of the specific items of business to come before the special meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares should be voted on a matter, the shares represented by your properly signed proxy will be voted "FOR" the proposal to approve the merger agreement and "FOR" the proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

Q:

What should I do if I receive more than one set of voting materials?

A:

If you hold shares of Skagit common stock in "street name" and also directly as a record holder or otherwise or if you hold shares of Skagit common stock in more than one brokerage account, you may receive more than one set of voting materials relating to the special meeting. Please complete, sign, date and return each proxy card or otherwise follow the voting instructions provided in this proxy statement/prospectus in order to ensure that all of your shares of Skagit common stock are voted. If you hold your shares in "street name" through a bank, brokerage firm or other nominee, you should follow the procedures provided by your bank, brokerage firm or other nominee to vote your shares.

Q:

What happens if I sell my shares of Skagit common stock before the special meeting?

A:

The record date is earlier than both the date of the special meeting and the effective time of the merger. If you transfer your shares of Skagit common stock after the record date but before the special meeting, you will, unless the transferee requests a proxy from you, retain your right to vote at the special meeting but will transfer the right to receive the merger consideration to the person to whom you transfer your shares. In order to receive the merger consideration, you must hold your shares at the effective time of the merger.

Q:

Who will solicit and pay the cost of soliciting proxies?

A:

Skagit's directors, officers and employees may solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies. Skagit will also request that brokerage houses and other custodians, nominees and fiduciaries forward these proxy materials to beneficial owners of Skagit common stock. Skagit will, upon request, reimburse such brokerage houses and custodians for their reasonable expenses in assisting with the solicitation of proxies.

8

---

Table of Contents

Skagit does not currently anticipate that it will engage an independent proxy solicitor to assist in the solicitation of proxies for the special meeting.

Q:

Should I send in my stock certificates now?

A:

No, please do NOT return your stock certificate(s) with your proxy now. After the effective time of the merger, each record holder, as of immediately prior to the effective time of the merger, of shares of Skagit common stock that are converted into the right to receive the merger consideration will receive a letter of transmittal and instructions from the exchange agent describing the procedures for surrendering their certificate or certificates representing shares of Skagit common stock.

Q:

Are there any voting agreements in place with Skagit shareholders?

A:

Each of the directors and executive officers of Skagit and/or their affiliates has entered into a voting and support agreement with Banner, in which each such person agreed, among other things, to vote in favor of the merger proposal and the proposal to adjourn or postpone the special meeting of the Skagit shareholders to a later date if there are not sufficient votes to approve the merger agreement, as well as certain other customary restrictions with respect to the voting and transfer of such person's shares of Skagit common stock.

Q:

What happens if the merger is not completed?

A:

If the merger is not completed, Skagit shareholders will not receive any consideration for their shares of Skagit common stock in connection with the merger. Instead, Skagit will remain an independent company. Under specified circumstances, Skagit may be required to pay Banner a fee with respect to the termination of the merger agreement, as described under the section entitled "The Merger Agreement—Termination Fee" beginning on page 97 of this proxy statement/prospectus.

Q:

Who can help answer any other questions I have?

A:

If you have additional questions about the merger, need assistance in submitting your proxy or voting your shares of Skagit common stock, or need additional copies of this proxy statement/prospectus or the enclosed proxy card, please contact Nancy K. Galbreath, Executive Assistant to the CEO, Skagit Bancorp, Inc., at 301 East Fairhaven Avenue, Burlington, Washington 98233, or at (360) 755-0411.

RISK FACTORS

        In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the caption "Cautionary Statement Regarding Forward-Looking Statements" on page 31, you should carefully consider the following risk factors in deciding whether to vote to approve the merger agreement. Additional risks and uncertainties not presently known to Banner or Skagit that are not currently believed to be important to you, if they materialize, also may adversely affect the merger and Banner as the surviving corporation in the merger.

        In addition, you should read and consider the risks and uncertainties associated with the business of Banner because these risks will relate to the combined company. Description of some of these risks and uncertainties can be found in Banner's Annual Report on Form 10-K for the year ended December 31, 2017 and subsequent Quarterly Reports on Form 10-Q, each of which are incorporated by reference into this proxy statement/prospectus. See the section entitled "Where You Can Find More Information" beginning on page 120.

The exchange ratio will not be adjusted in the event of any change in Banner's stock price. Because the market price of Banner common stock may fluctuate, you cannot be certain of the precise value of the merger consideration you may receive in the merger.

        At the time the merger is completed, each issued and outstanding share of Skagit common stock, except for certain shares held by Banner or Skagit (other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity or as a result of debts previously contracted) or a Skagit shareholder who properly exercises dissenters' right when and in the manner required under Chapter 23B.13 of the WBCA, will be converted into the right to receive 5.6664 shares of Banner common stock, subject to adjustment as provided in the merger agreement.

        There will be a time lapse between each of the date of this proxy statement/prospectus, the date on which Skagit shareholders vote to approve the merger agreement at the special meeting, and the date on which Skagit shareholders entitled to receive shares of Banner common stock under the merger agreement actually receive such shares. The market value of Banner common stock may fluctuate during these periods as a result of a variety of factors, including general market and economic conditions, changes in Banner's businesses, operations and prospects and regulatory considerations. Many of these factors are outside of the control of Skagit and Banner. Consequently, at the time Skagit shareholders must decide whether to approve the merger agreement, they will not know the actual market value of the shares of Banner common stock they may receive when the merger is completed. This value will not be known at the time of the special meeting and may be more or less than the current price of Banner common stock or the price of Banner common stock at the time of the special meeting.

Skagit's adjusted shareholders' equity could be an amount that results in a reduction in the exchange ratio and the merger consideration.

        The exchange ratio and the merger consideration will be reduced in the event that Skagit's adjusted shareholders' equity, as finally determined pursuant to the merger agreement, is less than $80 million. As a result, the exchange ratio may be less than 5.6664. Any reduction in the exchange ratio will result in a decline in the number of shares of Banner common stock and the value of the merger consideration received by Skagit shareholders. Moreover, adjusted shareholders' equity is measured as of the month-end prior to the closing (or, if the closing is expected to occur in the first eight days of a month, the preceding month-end). As a result, adjusted shareholders' equity is not known as of the date of this proxy statement/prospectus and may not be known at the time of the special meeting, and could increase or decrease during the period between the date of this proxy statement/prospectus or the date of the special meeting and the shareholders' equity measuring date

based on factors outside of the control of Skagit. See "The Merger Agreement—Merger Consideration—Potential Adjustment to Exchange Ratio" beginning on page 77.

Banner may be unable to successfully integrate Skagit's operations and may not realize the anticipated benefits of acquiring Skagit.

        Banner and Skagit have operated and, until the completion of the merger, will continue to operate, independently. The success of the merger, including anticipated benefits and cost savings, will depend, in part, on Banner's ability to successfully integrate Skagit's operations in a manner that results in various benefits, including, among other things, an expanded market reach and operating efficiencies and that does not materially disrupt existing customer relationships or result in decreased revenues due to loss of customers. The process of integrating operations could result in a loss of key personnel or cause an interruption of, or loss of momentum in, the activities of one or more of the surviving bank's businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the ability of Banner or Skagit to maintain relationships with customers and employees. The diversion of management's attention and any delays or difficulties encountered in connection with the merger and the integration of Skagit's operations could have an adverse effect on the business, financial condition, operating results and prospects of the surviving corporation after the merger.

        The success of the surviving corporation following the merger will depend in part on the ability of Banner to integrate the two businesses. If Banner experiences difficulties in the integration process, including those listed above, Banner may fail to realize the anticipated benefits of the merger in a timely manner or at all. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management's time and energy and could have an adverse effect on the surviving corporation's business, financial condition, operating results and prospects.

        Among the factors considered by the boards of directors of Banner and Skagit in connection with their respective approvals of the merger agreement were the benefits that could result from the merger. We cannot give any assurance that these benefits will be realized within the time periods contemplated or at all.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could prevent the consummation of the merger or have an adverse effect on the combined company following the merger.

        Before the transactions contemplated by the merger agreement, including the merger and the bank merger, may be completed, various approvals and/or waivers must be obtained from the bank regulatory and other governmental authorities, including the Federal Reserve Board, the FDIC and the DFI. In determining whether to grant these approvals, the regulators consider a variety of factors, including the regulatory standing of each party and the factors described under "The Merger—Regulatory Approvals" on page 72. An adverse development in either party's regulatory standing or these factors could result in an inability to obtain one or more approvals or delay their receipt. These governmental entities may impose conditions, limitations or costs, require divestitures or place restrictions on the conduct of Banner after the closing as a condition to the granting of such approvals or require changes to the terms of the merger or the bank merger. Such conditions or changes and the process of obtaining regulatory approvals could prevent the consummation of the merger if they contain or result in materially burdensome regulatory conditions or could have the effect of delaying completion of the merger or of imposing additional costs or limitations on Banner following the merger, any of which might have an adverse effect on the surviving corporation following the merger. The regulatory approvals may not be received at any time, may not be received in a timely fashion, and may contain conditions on the completion of the merger that adversely affect the surviving corporation's business following the closing, or which are not anticipated or cannot be met.

Table of Contents

The merger agreement may be terminated in accordance with its terms and the merger may not be completed.

        The merger agreement is subject to a number of conditions which must be satisfied or waived in order to complete the merger. For a summary of the conditions that must be satisfied or waived prior to completion of the merger, see the section entitled "The Merger Agreement—Conditions to Completion of the Merger" beginning on page 94 of this proxy statement/prospectus. These conditions to the closing of the merger may not be satisfied in a timely manner or at all, and, accordingly, the merger may be delayed or may not be completed.

        In addition, if the merger is not completed by April 25, 2019, either Banner or Skagit may choose not to proceed with the merger, and the parties can mutually decide to terminate the merger agreement at any time, before or after shareholder approval. In addition, Banner and Skagit may elect to terminate the merger agreement in certain other circumstances. If the merger agreement is terminated under certain circumstances, Skagit may be required to pay a termination fee of $7.75 million to Banner. See the section entitled "The Merger Agreement—Termination Fee" beginning on page 97 for a description of these circumstances.

Failure to complete the merger could negatively impact the stock price and the future business and financial results of Skagit.

        If the merger is not completed for any reason, including as a result of Skagit shareholders declining to approve the merger agreement, the ongoing business of Skagit may be adversely affected and, without realizing any of the benefits of having completed the merger, Skagit would be subject to a number of risks, including the following:

•

Skagit may experience negative reactions from the financial markets, including negative impacts on the price at which Skagit common stock may be sold;



•

Skagit may experience negative reactions from its customers, vendors and employees;



•

Skagit will have incurred substantial expenses and will be required to pay certain costs relating to the merger, whether or not the merger is completed;



•

the merger agreement places certain restrictions on the conduct of Skagit's businesses prior to completion of the merger. Such restrictions, the waiver of which is subject to the consent of Banner, may prevent Skagit from making certain acquisitions or taking certain other specified actions during the pendency of the merger (see the section entitled "The Merger Agreement—Conduct of Businesses of Skagit and Banner Prior to Completion of the Merger" beginning on page 85 of this proxy statement/prospectus for a description of the restrictive covenants applicable to Skagit); and



•

matters relating to the merger (including integration planning) will require substantial commitments of time and resources by Skagit management, which would otherwise have been devoted to other opportunities that may have been beneficial to Skagit as an independent company.

        In addition to the above risks, if the merger agreement is terminated and the Skagit board of directors seeks another merger or business combination, Skagit shareholders cannot be certain that Skagit will be able to find a party willing to offer equivalent or more attractive consideration than the consideration Banner has agreed to provide in the merger. If the merger agreement is terminated under certain circumstances, Skagit may be required to pay a termination fee of $7.75 million to Banner. See the section entitled "The Merger Agreement—Termination Fee" beginning on page 97.

Skagit will be subject to business uncertainties while the merger is pending, which could adversely affect its business.

        Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Skagit, and, consequently, the surviving corporation. These uncertainties may impair Skagit's ability to attract, retain and motivate key personnel until the merger is consummated and for a period of time thereafter, and could cause customers and others that deal with Skagit to seek to change their existing business relationships with Skagit. Employee retention at Skagit may be particularly challenging during the pendency of the merger, as employees may experience uncertainty about their roles with the surviving corporation following the merger. In addition, the merger agreement restricts Skagit from making certain acquisitions and taking other specified actions without the consent of Banner, and generally requires Skagit to continue its operations in the ordinary course, until the merger closes. These restrictions may prevent Skagit from pursuing attractive business opportunities that may arise prior to the completion of the merger. Please see the section entitled "The Merger Agreement—Conduct of Businesses of Skagit and Banner Prior to Completion of the Merger" beginning on page 85 for a description of the restrictive covenants to which Skagit is subject.

The merger agreement limits Skagit's ability to pursue alternatives to the merger.

        The merger agreement contains provisions that may discourage a third party from submitting an acquisition proposal to Skagit that might result in greater value to Skagit shareholders than the merger, or may result in a potential competing acquirer proposing to pay a lower per share price to acquire Skagit than it might otherwise have proposed to pay. These provisions include a general prohibition on Skagit soliciting or, subject to certain exceptions relating to the exercise of fiduciary duties by the Skagit board, entering into discussions with any third party regarding, an acquisition proposal or offers for competing transactions. Skagit also has an unqualified obligation to submit the proposal to approve the merger agreement to a vote of its shareholders, even if Skagit receives an alternative acquisition proposal that its board of directors believes is superior to the merger. In addition, Skagit may be required to pay Banner a termination fee of $7.75 million in certain circumstances involving acquisition proposals for competing transactions. See the sections entitled "The Merger Agreement—Termination of the Merger Agreement" and "The Merger Agreement—Termination Fee" beginning on pages 95 and 97, respectively.

Directors and executive officers of Skagit may have interests in the merger that are different from, or in addition to, the interests of Skagit shareholders.

        Directors and executive officers of Skagit may have interests in the merger that are different from, or in addition to, the interests of Skagit shareholders generally. These interests include, among others, the treatment of outstanding equity awards pursuant to the merger agreement, certain payments and benefits payable under change in control agreements entered into with executive officers, and rights to ongoing indemnification and insurance coverage by the surviving corporation for acts or omissions occurring prior to the merger. These interests also include Banner's agreement to invite Skagit's Chief Executive Officer to serve as a member of Banner's board following the effective time of the merger. The Skagit board was aware of and considered those interests, among other matters, in reaching its decisions to approve and adopt the merger agreement and the transactions contemplated thereby, and to recommend the approval of the merger agreement to Skagit shareholders. See the section entitled "The Merger—Interests of Directors and Executive Officers of Skagit in the Merger" beginning on page 68 of this proxy statement/prospectus for a more detailed description of these interests.

Table of Contents

The market price for Banner common stock may be affected by factors different from those that historically have affected Skagit.

        Upon completion of the merger, Skagit shareholders who do not exercise dissenters' rights will become holders of Banner common stock. Banner's businesses differ from those of Skagit, and accordingly the results of operations of Banner will be affected by some factors that are different from those currently affecting the results of operations of Skagit. For a discussion of the businesses of Banner and Skagit, see the section entitled "The Parties to the Merger" beginning on page 45 of this proxy statement/prospectus and the documents incorporated by reference referred to under the section entitled "Where You Can Find More Information" beginning on page 120, including, in particular, in the section entitled "Risk Factors" in Banner's Annual Report on Form 10-K for the year ended December 31, 2017.

Shares of Banner common stock to be received by Skagit shareholders as a result of the merger will have rights different from the shares of Skagit common stock.

        Upon completion of the merger, the rights of former Skagit shareholders will be governed by the articles of incorporation and bylaws of Banner and Washington corporate law. The rights associated with Banner common stock are different from the rights associated with Skagit common stock, which are governed by the articles of incorporation and bylaws of Skagit. Please see the section entitled "Comparison of Shareholders' Rights" beginning on page 105 for a discussion of the different rights associated with Banner common stock.

Skagit shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

        Currently, Skagit shareholders have the right to vote in the election of the board of directors of Skagit and the power to approve or reject any matters requiring shareholder approval under Washington law and Skagit's articles of incorporation and bylaws. Upon the completion of the merger, Skagit shareholders will become shareholders of Banner with a percentage ownership of Banner that is smaller than the shareholder's current percentage ownership of Skagit. After the merger, Skagit shareholders in the aggregate are expected to become owners of approximately 8.7% of the outstanding shares of Banner common stock (without giving effect to any shares of Banner common stock held by Skagit shareholders prior to the merger or any adjustment to the exchange ratio). Even if all former Skagit shareholders voted together on all matters presented to Banner's shareholders, the former Skagit shareholders would exercise significantly less influence over Banner after the merger relative to their influence over Skagit prior to the merger, and thus would have a less significant impact on the approval or rejection of future Banner proposals submitted to a shareholder vote.

Banner will incur significant transaction and merger-related costs in connection with the merger.

        Banner expects to continue to incur a number of non-recurring costs associated with completing the merger, combining the operations of the two companies and achieving desired synergies. These fees and costs have been, and will continue to be, substantial.

        Banner will incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Banner continues to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the merger and the integration of the two companies' businesses. Although Banner expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow Banner to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all. See the risk factor entitled "Banner may be unable to

successfully integrate Skagit's operations and may not realize the anticipated benefits of acquiring Skagit" above.

        Other significant non-recurring transaction costs related to the merger include, but are not limited to, fees paid to legal, financial and accounting advisors, severance and benefit costs and filing fees. Each of Banner and Skagit has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs and expenses of filing, printing and mailing this proxy statement/prospectus and all filing and other fees paid to the SEC in connection with the merger. The costs described above, as well as other unanticipated costs and expenses, could have a material adverse effect on the financial conditions and operating results of the surviving corporation following the closing of the merger. If the merger is not completed, Skagit and Banner would have to recognize these and other expenses without realizing the expected benefits of the merger.

The opinion received by the Skagit board of directors from Sandler O'Neill has not been, and is not expected to be, updated to reflect any changes in circumstances that may have occurred since the date of the opinion.

        The opinion delivered to the Skagit board of directors by Sandler O'Neill, financial advisor to Skagit, as to the fairness, from a financial point of view, of the exchange ratio provided for in the merger agreement to the holders of Skagit common stock speaks only as of July 25, 2018, the date of such opinion. Changes in the operations and prospects of Banner or Skagit, general market and economic conditions and other factors which may be beyond the control of Banner and Skagit may have altered the value of Banner or Skagit or the sale prices of shares of Banner common stock or Skagit common stock as of the date of this proxy statement/prospectus, or may alter such values and sale prices by the time the merger is completed. Sandler O'Neill does not have any obligation to update, revise or reaffirm its opinion to reflect subsequent developments and has not done so. Skagit does not currently anticipate asking Sandler O'Neill to update its opinion to address the fairness of the exchange ratio from a financial point of view at the time the merger is completed or as of any other date other than the date of its opinion. The Skagit board of directors' recommendation that Skagit shareholders vote "FOR" approval of the merger agreement, however, is made as of the date of this proxy statement/prospectus. See "The Merger—Opinion of Skagit's Financial Advisor" and Annex B to this proxy statement/prospectus.

Record Date and Quorum

        Skagit has set the close of business on September 4, 2018 as the record date for the special meeting, and only holders of record of Skagit common stock as of the record date are entitled to vote at the special meeting. You are entitled to receive notice of, and to vote at, the special meeting if you owned shares of Skagit common stock as of the close of business on the record date. As of the record date, there were 544,257 shares of Skagit common stock outstanding and entitled to vote and, accordingly, 362,838 shares of Skagit common stock must vote to approve the merger agreement for the merger to occur. You will have one vote on all matters properly coming before the special meeting for each share of Skagit common stock that you owned as of the record date.

        The presence, in person or represented by proxy, of shareholders who hold a majority of the shares entitled to vote at the special meeting constitutes a quorum for the purposes of the special meeting. Abstentions and broker non-votes, if any, are counted as present for purposes of establishing a quorum.

        If a quorum is not present, a majority of the shares represented at the special meeting may adjourn the special meeting.

Voting by Skagit's Directors and Executive Officers

        As of the record date, the directors and executive officers of Skagit and their affiliates beneficially owned and were entitled to vote approximately 130,630 shares of Skagit common stock representing approximately 24.0% of the shares of Skagit common stock outstanding on that date. Each of the directors and executive officers of Skagit and/or their affiliates has entered into a voting and support agreement with Banner, in which each such person agreed, among other things, to vote in favor of the merger proposal and the proposal to adjourn or postpone the special meeting of the Skagit shareholders to a later date if there are not sufficient votes to approve the merger agreement, as well as certain other customary restrictions with respect to the voting and transfer of such person's shares of Skagit common stock. For more information regarding the voting and support agreements, see "The Merger Agreement—Voting and Support Agreements" beginning on page 98 and Annex D to this proxy statement/prospectus which contains a form of the Skagit voting and support agreement.

        A total of approximately 130,630 shares of Skagit common stock, or approximately 24.0% of the shares of Skagit common stock outstanding on the record date for the special meeting, were subject to such voting and support agreements.

Vote Required

        The approval of the merger agreement requires the affirmative vote of Skagit shareholders holding at least two-thirds of the outstanding shares of Skagit common stock entitled to vote at the special meeting. For the approval of the merger agreement, you may vote "FOR," "AGAINST" or "ABSTAIN." If you fail to submit a proxy or to vote in person at the special meeting or if you vote to abstain, or if your shares of Skagit common stock are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares of Skagit common stock, it will have the same effect as a vote "against" the approval of the merger agreement.

        The approval of adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement requires the affirmative vote of the majority of the shares represented at the meeting and entitled to vote. If your shares of Skagit common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, your vote will be considered "against" the proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. If you fail to submit a proxy or vote in person at the special meeting or if your shares of Skagit common stock are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares of Skagit common stock, your shares of Skagit common stock will not be voted, and this will not have an effect on the vote to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

        If your shares of Skagit common stock are registered directly in your name with the transfer agent of Skagit, Skagit Bank, you are considered, with respect to those shares of Skagit common stock, the shareholder of record. If you are a shareholder of record, this proxy statement/prospectus and the enclosed proxy card have been sent directly to you by Skagit.

        If your shares of Skagit common stock are held through a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares of Skagit common stock held in "street name." In that case, this proxy statement/prospectus has been forwarded to you by your bank, brokerage firm or

Table of Contents

other nominee who is considered, with respect to those shares of Skagit common stock, the shareholder of record. As the beneficial owner, you have the right to direct your bank, brokerage firm or other nominee how to vote your shares by following their instructions for voting.

        Banks, brokerage firms and other nominees who hold shares of Skagit common stock in "street name" for their customers typically have authority to vote on "routine" proposals when they have not received voting instructions from beneficial owners. However, banks, brokerage firms and other nominees are precluded from exercising their voting discretion with respect to non-routine matters, such as the approval of the merger agreement and adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. As a result, absent specific voting instructions from the beneficial owner of such shares, banks, brokerage firms and other nominees are not empowered to vote such shares. A so-called "broker non-vote" results when banks, brokerage firms and other nominees return a valid proxy but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares.

Proxies

        If you are a shareholder of record, you may have your shares of Skagit common stock voted on matters presented at the special meeting in the following ways:

•

by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope; or



•

in person—you may attend the special meeting and cast your vote there.

        If you are a beneficial owner, you will receive instructions from your bank, brokerage firm or other nominee that you must follow in order to have your shares of Skagit common stock voted. Those instructions will identify which of the above choices are available to you in order to have your shares voted. Please note that if you are a beneficial owner and wish to vote in person at the special meeting, you must provide a legal proxy from your bank, brokerage firm or other nominee at the special meeting.

        If you submit a proxy by mailing a proxy card, your proxy card should be mailed in the accompanying prepaid reply envelope, and your proxy card must be filed with the Secretary of Skagit by the time the special meeting begins. Please do not send in your stock certificates with your proxy card. You will be provided at a later date a letter of transmittal and instructions regarding the surrender of your stock certificates. You should then send your Skagit stock certificates to the exchange agent, together with your completed and signed letter of transmittal.

        If you vote by proxy, the individuals named on the enclosed proxy card (each of them, with full power of substitution) will vote your shares of Skagit common stock in the way that you indicate. When completing the proxy card, you may specify whether your shares of Skagit common stock should be voted "for" or "against" or to "abstain" from voting on all, some or none of the specific items of business to come before the special meeting.

        If you properly sign your proxy card but do not mark the boxes showing how your shares of Skagit common stock should be voted on a matter, the shares of Skagit common stock represented by your properly signed proxy will be voted "FOR" the proposal to approve the merger agreement and "FOR" the proposal to approve adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

In addition, you must bring a form of government-issued personal photo identification with you to be admitted to the meeting.

        If your shares of Skagit common stock are held in "street name," then you are not the shareholder of record. In order for you to vote the shares that you beneficially own and that are held in "street name" in person at the special meeting, you must bring a legal proxy, executed in your favor, from the bank, brokerage firm or other nominee that was the record holder of your shares held in "street name" as of the record date (i) confirming that you were the beneficial owner of those shares as of the record date, (ii) stating the number of shares of which you were the beneficial owner that were held for your benefit at that time by that bank, brokerage firm or other nominee, and (iii) appointing you as the record holder's proxy to vote the shares covered by that proxy at the special meeting.

Revocations of Proxies

        You have the right to revoke a proxy at any time before it is exercised, and your last vote is the vote that will be counted. If you are a Skagit shareholder of record, you can write to Nancy K. Galbreath, Executive Assistant to the CEO, Skagit Bancorp, Inc., at 301 East Fairhaven Avenue, Burlington, Washington 98233, stating that you wish to revoke your proxy and requesting another proxy card. If you hold your shares through a bank, brokerage firm or other nominee, you can revoke your proxy by contacting the bank, brokerage firm or other nominee and asking for a new proxy card. If you attend the meeting, you must request a revocation of your submitted proxy and vote by ballot to revoke your proxy. Your attendance alone at the special meeting will not of itself constitute a revocation of your proxy.

        If you have any questions or need assistance voting your shares, please contact Nancy K. Galbreath, Executive Assistant to the CEO, Skagit Bancorp, Inc., at 301 East Fairhaven Avenue, Burlington, Washington 98233 or at (360) 755-0411.

SHAREHOLDERS WHO ATTEND THE SPECIAL MEETING MAY REVOKE THEIR PROXIES BY REQUESTING A REVOCATION OF THEIR SUBMITTED PROXY AND VOTING IN PERSON.

Solicitation of Proxies; Payment of Solicitation Expenses

        Skagit's directors, officers and employees may solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies. Skagit will also request that brokerage houses and other custodians, nominees and fiduciaries forward these proxy materials to beneficial owners of Skagit common stock. Skagit will, upon request, reimburse such brokerage houses and custodians for their reasonable expenses in assisting with the solicitation of proxies.

THE MERGER

        The following discussion contains certain information about the merger. The description in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached as Annex A and is incorporated by reference into this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the merger that is important to you. You are encouraged to read the merger agreement carefully and in its entirety. This section is not intended to provide you with any factual information about Skagit or Banner. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings Banner makes with the SEC that are incorporated by reference into this document, as described in the section entitled "Where You Can Find More Information" beginning on page 120 of this proxy statement/prospectus.

Terms of the Merger

        The merger agreement provides that, subject to the terms and conditions therein, Skagit will merge with and into Banner with Banner surviving the merger as the surviving corporation. Immediately following the merger, Skagit Bank, Skagit's wholly owned bank subsidiary, will merge with and into Banner's wholly owned bank subsidiary, Banner Bank, with Banner Bank continuing as the surviving entity.

        In the merger, each outstanding share of Skagit common stock, other than certain shares held by Banner or Skagit (in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity or as a result of debts previously contracted) or by a Skagit shareholder who properly exercises dissenters' right when and in the manner required under Chapter 23B.13 of the WBCA, will be converted into the right to receive 5.6664 shares of Banner common stock, subject to the adjustment described in the section entitled "The Merger Agreement—Merger Consideration."

Background of the Merger

        As part of its continuous effort to enhance long-term value for Skagit shareholders, the Skagit board of directors periodically evaluates the strategic direction and business objectives of Skagit. This process entails consideration of, among other things, the economic, regulatory and competitive conditions in which Skagit operates, trends in the financial services industry, as well as Skagit's history, long-term business strategy and objectives.

        As part of this evaluation, during the latter half of 2017, the Skagit board of directors identified a growing set of challenges facing the community banking industry in general and, in some cases, Skagit specifically. In particular, the Skagit board of directors recognized the need for increased scale to offset persistently high regulatory compliance costs, the industry-wide proliferation of technology that could not be economically accessed or implemented by Skagit at its then-existing scale or with its then-existing resources, and the continued, strong competition for customers from other banks, credit unions and financial technology companies. The Skagit board of directors also considered the relative illiquidity of Skagit common stock and the importance to Skagit's shareholder base of accessing a source of liquidity to monetize their investment in Skagit. The Skagit board of directors also monitored commercial bank valuations and noted the increase in stock market and M&A valuations across the industry since November, 2016.

        In late September, 2017, as part of Skagit management's normal practice of periodically receiving market updates from financial advisors, a representative of Sandler O'Neill met in-person with Cheryl R. Bishop, Skagit's Chief Executive Officer, and Ken Johnson, Skagit's President and Chief Operating Officer, to discuss trends in the community banking industry and Skagit's financial position and trajectory, including recent stock market and M&A valuations in the community banking industry.

Table of Contents

Following the meeting, Ms. Bishop and Mr. Johnson, based on discussion with members of the Skagit board of directors, invited Sandler O'Neill to discuss these topics with the Skagit board of directors at Skagit's regularly scheduled board of directors' meeting in December 2017.

        On December 19, 2017, Skagit's board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill participated in the meeting at the invitation of the board of directors. At the meeting, representatives of Sandler O'Neill led a discussion with the directors and members of Skagit's senior management team, regarding trends in the community banking industry, Skagit's financial position and potential strategic alternatives that Skagit could pursue, including continued stand-alone operations, an acquisition of a smaller target, a strategic merger with a similarly sized bank or a strategic business combination with a larger financial institution. The discussion included a general assessment of the viability and execution risk of each strategic alternative and the likely impact of each such strategic alternative on the value of Skagit common stock. Based on the discussion, including a review of potential business combination partners and acquisition candidates, the Skagit board of directors determined that an acquisition of a smaller target or strategic merger with a similarly sized bank was not a viable option at that time. As part of the discussion, representatives of Sandler O'Neill and members of the Skagit board of directors discussed a range of potential values Skagit might expect to receive in a strategic business combination transaction as compared to the range of potential future values and net present values if Skagit were to remain independent and achieve Skagit management's financial performance forecast. The Skagit board of directors also discussed with management the risks to Skagit of continuing to operate on a stand-alone basis. The Skagit board of directors also discussed with representatives of Sandler O'Neill the landscape of potential larger strategic business combination partners for Skagit and the potential effects of a business combination transaction on Skagit's employees, customers, communities and other constituents. The Skagit board of directors was of the view that, if executed successfully, a strategic business combination transaction between Skagit and a larger financial institution could maximize shareholder value while minimizing any adverse effects on Skagit's other constituents. At the conclusion of the meeting, the Skagit board of directors determined that further consideration of a strategic business combination transaction was appropriate, and invited Sandler O'Neill to provide a follow-up presentation at the next regularly scheduled board meeting in January 2018.

        On January 2, 2018, the Skagit board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill and Miller Nash Graham and Dunn LLP, which we refer to as "MNGD," corporate counsel to Skagit, participated in the meeting. At the meeting, representatives of MNGD provided the Skagit board of directors with an overview of their fiduciary duties, including in the context of a strategic business combination transaction. Sandler O'Neill led a more detailed discussion with the directors regarding the strategic alternative of a strategic business combination between Skagit and a larger strategic partner. The discussion included an overview of the timeline and due diligence requirements and key procedural steps in connection with a potential strategic business combination transaction, as well as the landscape of prospective strategic partners and a range of potential values that Skagit might expect to realize in such a transaction. At the conclusion of the meeting, the Skagit board of directors authorized Sandler O'Neill to reach out to select potential strategic partners to determine whether such potential partners had interest in Skagit, and if so, on what terms.

        On February 6, 2018, Skagit formally engaged Sandler O'Neill to act as its financial advisor in connection with Skagit's further exploration of strategic alternatives, including a potential strategic business combination transaction.

        Later in February 2018, as directed by the Skagit board of directors, Sandler O'Neill began contacting four financial institutions which were identified by Sandler O'Neill, senior management of Skagit and the Skagit board of directors as potential strategic partners that might be interested in pursuing a transaction with Skagit. Each party was invited to sign a confidentiality agreement and

Table of Contents

receive an introductory package of confidential information regarding Skagit's financial condition and operations. Skagit entered into confidentiality agreements with three bank holding companies that expressed interest in considering a potential strategic business combination transaction, including a confidentiality agreement with Banner that was entered into on March 29, 2018. The other two bank holding companies that entered into confidentiality agreements with Skagit are referred to as "Party A" and "Party B" respectively.

        On March 26, 2018, the Skagit board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. Representatives of Sandler O'Neill provided an update to the Skagit board of directors on the exploration of strategic alternatives, including a report of the contacts made and responses received. The Skagit board of directors instructed management to provide additional information and due diligence to interested parties and for Sandler O'Neill to proceed with soliciting non-binding indications of interest from interested parties.

        In March and April 2018, Skagit's management team held in-person meetings with each of the prospective acquirors who had signed a confidentiality agreement, including an in-person meeting with representatives of Banner on April 10, 2018. At the meeting with Banner, representatives of Skagit provided an overview of Skagit's operations, financial condition and strategy, and the representatives of Skagit and the representatives of Banner also discussed the cultures of the two companies and the complementary nature of their branch locations and strategies.

        In late March, 2018, Party A informed representatives of Sandler O'Neill that it would not proceed further with exploring a transaction with Skagit.

        Throughout April, 2018, representatives of Banner continued their due diligence review of Skagit and requested and received additional due diligence materials from Skagit.

        In mid-April, 2018, as directed by the Skagit board of directors, Sandler O'Neill requested that Banner and Party B submit written non-binding indications of interest for a potential strategic business combination transaction with Skagit. In late April, 2018, Party B indicated to Sandler O'Neill that, while it could potentially be interested in a strategic transaction with Skagit at some point in the future, it was focused on other priorities and was not in a position to submit an indication of interest at that time, and that it was uncertain when or if it would be able to submit an actionable proposal in the future.

        On April 29, 2018, Banner submitted an indication of interest, which provided a non-binding proposal for an all-stock transaction based on a fixed exchange ratio of 5.6634 shares of Banner common stock per share of Skagit common stock. The indication of interest described certain other terms of a proposed transaction, including the invitation for Ms. Bishop to join the Banner board of directors following closing of the transaction and a customary termination fee payable by Skagit under certain circumstances. The indication of interest was contingent on Skagit agreeing to a 60-day exclusivity period during which Skagit would not, among other things, solicit proposals from or provide confidential information to other potential strategic business combination partners.

        On May 1, 2018, Skagit's board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. MNGD provided a brief overview of directors' fiduciary duties. Representatives of Sandler O'Neill provided an update on the events since the prior Skagit board meeting on March 26, 2018, including an overview of the written indication of interest from Banner. Based on Banner's stock price at the time of the meeting, the merger consideration proposed in Banner's indication of interest was valued at approximately $329 per share of Skagit common stock, or $180 million in the aggregate. With the assistance of representatives of Sandler O'Neill and MNGD, the Skagit board of directors considered the Banner indication of interest and, based on publicly available information, analyzed Banner's stock valuation and prospects, including the

Table of Contents

risks to Banner's business. The Skagit board of directors discussed the valuation, risks and benefits of the Banner indication of interest, including, among other things, the active trading market and liquidity for Banner common stock and Banner's history of paying cash dividends. The Skagit board of directors also discussed the potential effect of a transaction with Banner on Skagit's employees, customers, communities and other constituencies. The Skagit board of directors determined that a merger with Banner had the potential to maximize value for Skagit shareholders and to be in the best interest of Skagit and its other constituents, and that it was in the best interest of Skagit and its shareholders to engage in negotiations with Banner with the goal of obtaining the highest merger consideration possible. At the conclusion of the meeting, the Skagit board of directors directed Sandler O'Neill to propose an exchange ratio of 6.0000 shares of Banner common stock per share of Skagit common stock and confirm certain of the non-financial terms in the Banner indication of interest.

        Following the board meeting, representatives of Sandler O'Neill contacted Peter Conner, Banner's Chief Financial Officer, and communicated the feedback from the Skagit board of directors requesting an increased exchange ratio of 6.0000 shares of Banner common stock per share of Skagit common stock. Banner responded with a revised indication of interest, which included an exchange ratio of 5.8195 shares of Banner common stock per share of Skagit common stock, which represented an implied value of approximately $337.94 per share of Skagit common stock based on Banner's stock price on April 27, 2018.

        On May 3, 2018, the Skagit board of directors held a regularly scheduled meeting to discuss Banner's revised indication of interest. Representatives of Sandler O'Neill participated in the meeting. After review of the updated Banner indication of interest and further discussion of the benefits and risks of a transaction with Banner as compared to Skagit's stand-alone prospects, the Skagit board of directors determined that given the strength of the Banner indication of interest, as well as the fact that none of the other potential counterparties contacted by Sandler O'Neill had expressed actionable interest in a strategic business combination transaction with Skagit, it was in the best interests of Skagit and its shareholders for Skagit to agree to negotiate exclusively with Banner based on the terms of the Banner indication of interest. The Skagit board of directors authorized Ms. Bishop to execute the indication of interest, which was executed later that day.

        Throughout May and June 2018, each of Banner and Skagit conducted due diligence on the other party, with the parties exchanging information concerning, among other things, their businesses, financial positions, strategies and operations. In addition to several conversations between individual members of management of the parties, the management teams of Banner and Skagit held in-person meetings to discuss due diligence topics.

        In late June, 2018, Banner's counsel, Wachtell, Lipton, Rosen & Katz, which we refer to as "Wachtell Lipton," distributed a draft of the merger agreement to MNGD. The draft merger agreement provided, among other things, for a restriction on Skagit's ability to pay any dividends between execution of the merger agreement and closing of the merger and a condition to the consummation of the merger that Skagit have a least a specified minimum amount of shareholders' equity as of the closing.

        On June 28, 2018, the Skagit board of directors held a special meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. At the meeting, the Skagit board of directors received an update on the process from Sandler O'Neill and an overview of the draft merger agreement provided by MNGD.

        On July 3, 2018, the Skagit board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. At the meeting, representatives of Sandler O'Neill led a discussion with the Skagit board of directors regarding due diligence and transaction negotiations, and representatives of MNGD led a discussion regarding the draft merger agreement. After discussion, questions and consideration, the Skagit board of directors authorized Skagit

management, Sandler O'Neill and MNGD to continue negotiation of the merger agreement, but specifically instructed that management and the advisors pursue the following terms, among others: (i) Skagit would be permitted to pay its ordinary course semi-annual cash dividend prorated on a quarterly basis between execution of the merger agreement and closing of the merger; and (ii) the minimum equity condition would be removed from the merger agreement, or would be replaced with a symmetrical price adjustment mechanism based on Skagit's adjusted shareholders' equity at a specified time prior to closing. Following the meeting, MNGD returned to Wachtell Lipton a revised draft of the merger agreement.

        In mid-July, Mr. Conner contacted a representative of Sandler O'Neill and expressed Banner's continued desire to proceed with the transaction, but indicated that through due diligence, Banner had discovered that certain of its value assumptions underlying the exchange ratio in the Banner indication of interest were not supported. In order to compensate for this development, Banner proposed a revised exchange ratio of 5.5978 shares of Banner common stock per share of Skagit common stock. Thereafter, Wachtell Lipton returned a revised draft of the merger agreement to MNGD, which reflected the revised exchange ratio, accepted Skagit's proposal that Skagit be permitted to pay cash dividends between the execution of the merger agreement and closing of the merger and replaced the minimum equity condition with a price adjustment mechanism.

        On July 13, 2018 the Skagit board of directors held a special meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. At the meeting, representatives of Sandler O'Neill and MNGD led a discussion with the Skagit board of directors regarding the negotiations with Banner and the current draft of the merger agreement. The Skagit board of directors discussed Banner's due diligence findings and Banner's proposed revised terms. The Skagit board of directors also considered the relative merits of Skagit's stand-alone prospects and the proposed transaction with Banner at the revised exchange ratio. Following the discussion, the Skagit board of directors directed Sandler O'Neill to proceed with negotiation of the transaction terms but to propose an enhanced exchange ratio and insist that Skagit be entitled to pay a special dividend to its shareholders prior to closing in an amount equal to any excess of Skagit's shareholders' equity above a specified threshold, effectively making the purchase price adjustment symmetrical. Following the meeting, Daniel R. Peth, the Chairman of the Skagit board of directors, contacted Mr. Grescovich, Banner's President and Chief Executive Officer, to request that Banner consider an increased exchange ratio and representatives of Sandler O'Neill contacted Mr. Conner and provided further support for an increased exchange ratio.

        In the following days, Mr. Conner contacted a representative of Sandler O'Neill and informed him that Banner was prepared to agree to an exchange ratio of 5.6664 shares of Banner common stock per share of Skagit common stock and accept Skagit's proposal regarding the pre-closing special dividend.

        On July 17, 2018, the Skagit board of directors held a regularly scheduled meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. At the meeting, the Skagit board of directors received an update on the negotiations with Banner, including the revised exchange ratio of 5.6664 shares of Banner common stock per share of Skagit common stock. Based on Banner's then-current stock price, the 5.6664 exchange ratio was valued at approximately $346 per share of Skagit common stock, or approximately $190 million in the aggregate. Following discussion, the Skagit board of directors confirmed its desire to continue negotiation of a merger agreement incorporating the revised exchange ratio. Following the meeting, a representative of Sandler O'Neill contacted Mr. Conner and confirmed Skagit's acceptance of the revised exchange ratio of 5.6664 shares of Banner common stock per share of Skagit common stock and MNGD returned a revised draft of the merger agreement to WLRK, which reflected the revised exchange ratio and Skagit's right to pay a pre-closing special dividend.

        Between July 18, 2018 and July 24, 2018, Skagit and Banner, along with their financial and legal advisors, finalized the merger agreement and related documents.

        On July 25, 2018, the Skagit board of directors held a special meeting. Representatives of Sandler O'Neill and MNGD participated in the meeting. Representatives of MNGD discussed with the directors, as they had previously done, the directors' fiduciary duties and legal obligations in the context of considering the transaction with Banner, reviewed the merger agreement and related documents and provided an updated report on legal due diligence findings with respect to Banner. Skagit management provided an updated report on its business due diligence with respect to Banner. A representative of Sandler O'Neill reviewed the financial aspects of the proposed merger, including discussing the various financial methodologies used in its analysis, and provided Sandler O'Neill's oral opinion to the Skagit board of directors, subsequently confirmed in writing, to the effect that, as of July 25, 2018, the exchange ratio provided in the merger agreement was fair to the holders of Skagit common stock from a financial point of view. The Skagit board of directors asked questions and discussed each of the reports and presentations, considered the relative merits of Skagit's stand-alone prospects and the proposed transaction with Banner on the terms provided in the merger agreement, and considered the effect of the proposed transaction with Banner on Skagit's employees, customers, communities and other constituencies. Following this discussion and the receipt of Sandler O'Neill's oral opinion, the Skagit board of directors unanimously (i) determined that the merger, on the terms and conditions set forth in the merger agreement, was in the best interests of Skagit and its shareholders, (ii) approved entering into the merger agreement and related agreements, (iii) directed that the merger agreement and the transactions contemplated thereby be submitted to the Skagit shareholders for approval at a meeting of the Skagit shareholders and (iv) determined to recommend that the Skagit shareholders approve the merger agreement and the transactions contemplated thereby.

        Later on July 25, 2018, the merger agreement and related documents were executed, and Banner and Skagit publicly announced the merger in a joint press release.

Skagit's Reasons for the Merger; Recommendation of the Skagit Board of Directors

        At a meeting held on July 25, 2018, the Skagit board of directors unanimously determined that the merger, on the terms and conditions set forth in the merger agreement, was in the best interests of Skagit and its shareholders. In the course of reaching this determination and making the related decision to approve the merger agreement and recommend that Skagit shareholders vote "FOR" the proposal to approve the merger agreement, the board of directors evaluated the merger and the merger agreement in consultation with the management of Skagit and Skagit's financial advisor and legal counsel. In making its determination and reaching its decision to approve the merger agreement and recommend that Skagit shareholders vote "FOR" the proposal to approve the merger agreement, the Skagit board of directors considered a number of factors, including the following factors that the Skagit board of directors viewed as generally supporting its determination and decisions:

•

the value and form of consideration to be received by Skagit shareholders in the merger;



•

its belief that the value of consideration to be received by Skagit shareholders in the merger was more favorable to Skagit shareholders than the potential value that might result from other alternatives reasonably available to Skagit in light of a number of factors, including the risks and uncertainties associated with such alternatives;



•

that as a result of negotiations with Banner, the exchange ratio of 5.6664 shares of Banner common stock per share of Skagit common stock was the highest consideration per share of Skagit common stock that Banner was willing to pay at the time of those negotiations;



•

the expectation that the merger will generally be a tax-free transaction to Skagit shareholders with respect to the Banner common stock received by virtue of the merger;



•

the fact that several potential counterparties were contacted regarding their interest in a transaction with Skagit and two counterparties other than Banner entered into confidentiality

52

Table of Contents

agreements and commenced diligence, and that no potential counterparties other than Banner submitted an actionable proposal for a business combination transaction;

•

the historical and prospective business of Skagit on a stand-alone basis and the risks and challenges associated with successfully executing on Skagit's stand-alone strategic plan, including risks relating to Skagit's relatively small scale, the cost of adopting new technology, and competitive pressures;



•

the historical trading ranges for Banner common stock;



•

information concerning Banner's financial condition and results of operations, including the expectation that Banner will be well-capitalized upon completion of the merger;



•

the likely impact of the merger on the employees and customers of Skagit and the strategic plans, methods of operation and organizational structure of Banner;



•

the future employment opportunities for the existing employees of Skagit Bank;



•

the complementary nature of the cultures of Skagit and Banner, which the Skagit board of directors believes will facilitate integration and implementation of the merger and benefit Skagit shareholders in their ownership of the combined company;



•

the oral opinion of Sandler O'Neill provided to the Skagit board of directors on July 25, 2018 and subsequently confirmed in writing, to the effect that, as of such date, the exchange ratio provided for in the merger agreement was fair to the holders of Skagit common stock from a financial point of view, as more fully described below under "—Opinion of Skagit Bancorp's Financial Advisor";



•

the expectation that Skagit shareholders would have the opportunity to continue to participate in the growth of the combined company and expense savings as a result of the merger, and would also benefit from the significantly greater liquidity of the trading market for Banner common stock;



•

the fact that Banner's common stock is widely held and has an active trading market;



•

the fact that Skagit's stock is not actively traded or quoted and has limited liquidity;



•

that Banner has historically paid a cash dividend on its common stock and that Skagit shareholders would be able to participate in any future dividends paid by Banner upon completion of the merger;



•

the terms and conditions of the merger agreement, including:



•

the limited and otherwise customary conditions to Banner's obligations to complete the merger, and the Skagit board of directors' expectation that such conditions will be satisfied in a timely manner;



•

the provisions in the merger agreement that, under certain circumstances and subject to certain conditions, provide for the ability of the Skagit board of directors to respond to an unsolicited acquisition proposal that the board of directors determines in good faith constitutes or is reasonably likely to result in a superior proposal;



•

the provisions of the merger agreement that provide for the ability of the Skagit board of directors, under certain circumstances following the failure of Skagit shareholders to approve the merger agreement at a meeting of Skagit shareholders and subject to certain conditions, including the payment of a termination fee, to terminate the merger agreement to enter into a definitive agreement with respect to a superior proposal; and

•

the fact that under the WBCA, the Skagit stockholders who do not vote in favor of the approval of the merger agreement and otherwise comply with the requirements of the WBCA will have the right to pursue their dissenters' rights under the WBCA if the merger is completed.

        The Skagit board of directors also considered a number of uncertainties and risks in its deliberations concerning the transactions contemplated by the merger agreement, including the following:

•

that the merger consideration will be paid through the issuance of a fixed number of shares of Banner common stock, and any decrease in the market price of Banner common stock after the date of the merger agreement will result in a reduction in the value of the merger consideration to be received by Skagit shareholders at the effective time of the merger;



•

that Skagit shareholders will not necessarily know or be able to calculate in advance the actual value of the merger consideration which they would receive upon completion of the merger;



•

the possibility that the number of shares of Banner common stock Skagit shareholders will receive at the effective time of the merger will be reduced pursuant to the adjustment procedures described under "The Merger Agreement—Merger Consideration—Potential Adjustment to Exchange Ratio";



•

the fact that completion of the merger is subject to conditions that are not fully in Skagit's control, such as the approval of Skagit shareholders and the receipt of regulatory approvals;



•

the fact some of Skagit's directors and executive officers may have certain interests, including financial interests, in the merger that may be different from, or in addition to, those of Skagit shareholders generally. See "—Interests of Skagit's Directors and Executive Officers in the Merger";



•

the possible disruption to Skagit's business that may result from the announcement of the merger and the resulting distraction of management's attention from the day-to-day operations of Skagit's business;



•

the provisions in the merger agreement restricting Skagit from soliciting third-party proposals and providing for the payment of a termination fee in certain circumstances, which the Skagit board of directors understood would potentially limit the willingness of a third party to propose a business combination transaction with Skagit and the ability of Skagit to enter into a such a transaction; and



•

the restrictions contained in the merger agreement on the operation of Skagit's business during the period between signing of the merger agreement and completion of the merger.

        The foregoing discussion of the reasons that led the Skagit board of directors to approve the merger agreement and recommend that Skagit's shareholders vote in favor of the proposal to approve the merger agreement includes the material factors considered by the Skagit board of directors in connection with its evaluation of the merger, but is not intended to be exhaustive. In reaching its determination to approve and recommend the transaction, the Skagit board of directors based its determination on the totality of the information available to it and did not assign any relative or specific weights to the reasons considered in reaching that determination. Individual directors may have given differing weights to different reasons.

        After careful consideration, the Skagit board of directors unanimously determined that the merger, on the terms and conditions set forth in the merger agreement, was in the best interests of Skagit and its shareholders.

        The Skagit board of directors unanimously recommends that Skagit shareholders vote "FOR" the proposal to approve the merger agreement and "FOR" the proposal to approve adjournment of the

special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

Opinion of Skagit's Financial Advisor

        Skagit retained Sandler O'Neill, pursuant to an engagement letter dated February 6, 2018, to act as an independent financial advisor to the Skagit board of directors in connection with Skagit's consideration of a possible business combination. Sandler O'Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O'Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

        Sandler O'Neill acted as an independent financial advisor in connection with the proposed transaction and participated in certain of the negotiations leading to the execution of the merger agreement. At the July 25, 2018 meeting at which the Skagit board of directors considered and discussed the terms of the merger agreement and the merger, Sandler O'Neill delivered to the Skagit board of directors its oral opinion, which was subsequently confirmed in writing, to the effect that, as of July 25, 2018, the exchange ratio provided for in the merger agreement was fair to the holders of Skagit common stock from a financial point of view. The full text of Sandler O'Neill's opinion is attached as Annex B to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O'Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Skagit common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

        Sandler O'Neill's opinion speaks only as of the date of the opinion. The opinion was directed to the Skagit board of directors in connection with its consideration of the merger agreement and the merger and does not constitute a recommendation to any shareholder of Skagit as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger agreement and the merger. Sandler O'Neill's opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of Skagit common stock and does not address the underlying business decision of Skagit to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Skagit or the effect of any other transaction in which Skagit might engage. Sandler O'Neill did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of Skagit or Banner, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder, including the exchange ratio to be received by the holders of Skagit common stock. Sandler O'Neill's opinion was approved by Sandler O'Neill's fairness opinion committee.

        In connection with its opinion, Sandler O'Neill reviewed and considered, among other things:

•

a draft of the merger agreement, dated July 23, 2018;



•

certain publicly available financial statements and other historical financial information of Skagit that Sandler O'Neill deemed relevant;



•

certain publicly available financial statements and other historical financial information of Banner that Sandler O'Neill deemed relevant;



•

certain internal financial projections for Skagit for the year ending December 31, 2018, as provided by the senior management of Skagit, as well as a long-term earnings per share growth

rate and dividend payout ratio for the years thereafter, as directed by the senior management of Skagit;

•

publicly available consensus analyst net income estimates for Banner for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate for the years thereafter and dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Banner;



•

the pro forma financial impact of the merger on Banner based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as estimated revenue impacts following the closing of the merger, as directed by the senior management of Banner;



•

the publicly reported historical price and trading activity for Banner common stock, including a comparison of certain stock market information for Banner common stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded;



•

a comparison of certain financial information for Skagit and Banner with similar financial institutions for which information is publicly available;



•

the financial terms of certain recent business combinations in the banking industry (on a nationwide basis), to the extent publicly available;



•

the current market environment generally and the banking environment in particular; and



•

such other information, financial studies, analyses and investigations and financial, economic and market criteria as Sandler O'Neill considered relevant.

        Sandler O'Neill also discussed with certain members of the management of Skagit and its representatives the business, financial condition, results of operations and prospects of Skagit and held similar discussions with certain members of the senior management of Banner and its representatives regarding the business, financial condition, results of operations and prospects of Banner.

        In performing its review, Sandler O'Neill relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by Sandler O'Neill from public sources, that was provided to Sandler O'Neill by Skagit or Banner or their respective representatives or that was otherwise reviewed by Sandler O'Neill, and Sandler O'Neill assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Sandler O'Neill relied on the assurances of the respective managements of Skagit and Banner that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Sandler O'Neill was not asked to and did not undertake an independent verification of any of such information and Sandler O'Neill did not assume any responsibility or liability for the accuracy or completeness thereof. Sandler O'Neill did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Skagit or Banner, or any of their respective subsidiaries, nor was Sandler O'Neill furnished with any such evaluations or appraisals. Sandler O'Neill rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of Skagit or Banner. Sandler O'Neill did not make an independent evaluation of the adequacy of the allowance for loan losses of Skagit or Banner or of the combined entity after the merger and Sandler O'Neill did not review any individual credit files relating to Skagit or Banner. Sandler O'Neill assumed, with Skagit's consent, that the respective allowances for loan losses for both Skagit and Banner were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

        In preparing its analyses, Sandler O'Neill used certain internal financial projections for Skagit for the year ending December 31, 2018, as provided by the senior management of Skagit, as well as a long-term earnings per share growth rate and dividend payout ratio for the years thereafter, as directed by the senior management of Skagit. In addition, Sandler O'Neill used publicly available consensus analyst net income estimates for Banner for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate for the years thereafter and dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Banner. Sandler O'Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as estimated revenue impacts following the closing of the merger, as directed by the senior management of Banner. With respect to the foregoing information, the respective senior managements of Skagit and Banner confirmed to Sandler O'Neill that such information reflected (or, in the case of the publicly available consensus analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgments of those respective managements as to the future financial performance of Skagit and Banner, respectively, and the other matters covered thereby, and Sandler O'Neill assumed that the future financial performance reflected in such information would be achieved. Sandler O'Neill expressed no opinion as to such information, or the assumptions on which such information was based. Sandler O'Neill also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of Skagit or Banner since the date of the most recent financial statements made available to Sandler O'Neill. Sandler O'Neill assumed in all respects material to its analysis that Skagit and Banner would remain as going concerns for all periods relevant to Sandler O'Neill's analysis.

        Sandler O'Neill also assumed, with Skagit's consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Skagit, Banner or the merger or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with Skagit's consent, Sandler O'Neill relied upon the advice that Skagit received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement. Sandler O'Neill expressed no opinion as to any such matters.

        Sandler O'Neill's opinion was necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to Sandler O'Neill as of, the date thereof. Events occurring after the date thereof could materially affect Sandler O'Neill's opinion. Sandler O'Neill has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Sandler O'Neill expressed no opinion as to the trading value of Banner common stock at any time or what the value of Banner common stock would be once it is actually received by the holders of Skagit common stock.

        In rendering its opinion, Sandler O'Neill performed a variety of financial analyses. The summary below is not a complete description of the analyses underlying Sandler O'Neill's opinion or the presentation made by Sandler O'Neill to the Skagit board of directors, but is a summary of the material

57

Table of Contents

analyses performed and presented by Sandler O'Neill. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O'Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O'Neill's comparative analyses described below is identical to Skagit or Banner and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of Skagit and Banner and the companies to which they are being compared. In arriving at its opinion, Sandler O'Neill did not attribute any particular weight to any analysis or factor that it considered. Rather, Sandler O'Neill made qualitative judgments as to the significance and relevance of each analysis and factor. Sandler O'Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Sandler O'Neill made its determination as to the fairness of the exchange ratio from a financial point of view on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

        In performing its analyses, Sandler O'Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which are beyond the control of Skagit, Banner and Sandler O'Neill. The analyses performed by Sandler O'Neill are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Sandler O'Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Skagit board of directors at its July 25, 2018 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O'Neill's analyses do not necessarily reflect the value of Skagit common stock or the prices at which Skagit common stock or Banner common stock may be sold at any time. The analyses of Sandler O'Neill and its opinion were among a number of factors taken into consideration by the Skagit board of directors in making its determination to approve the merger agreement and should not be viewed as determinative of the exchange ratio or the decision of the Skagit board of directors or management with respect to the fairness of the merger. The type and amount of consideration payable in the merger were determined through negotiation between Skagit and Banner.

Summary of Exchange Ratio and Implied Transaction Metrics

        Sandler O'Neill reviewed the financial terms of the proposed merger. Subject to certain adjustments and termination provisions, as more fully described in the section entitled "The Merger Agreement," at the effective time of the merger, each share of Skagit common stock issued an outstanding prior to the effective time of the merger, except for certain shares of Skagit common stock as specified in the merger agreement, will be converted into the right to receive 5.6664 shares of the common stock of Banner. Based on the closing price of Banner common stock on July 24, 2018 of $62.02, Sandler O'Neill calculated an implied transaction price per share of Skagit common stock of $351.43 and an aggregate implied transaction value of approximately $192.4 million in exchange for all Skagit common stock, restricted stock and options issued and outstanding as of July 24, 2018. Based upon historical financial information for Skagit as of or for the last twelve months (which we refer to

as "LTM") ended June 30, 2018 and internal financial projections for Skagit for the year ended December 31, 2018, as provided by the senior management of Skagit, Sandler O'Neill calculated the following implied transaction metrics.

Skagit Comparable Company Analyses

        Sandler O'Neill used publicly available information as of March 31, 2018, unless otherwise noted, and information provided by Skagit senior management as of June 30, 2018, to compare selected financial information for Skagit with a group of banks selected by Sandler O'Neill (which we refer to as the "Skagit Peer Group"). The Skagit Peer Group consisted of publicly-traded banks headquartered in the western region of the United States with total assets between $750 million and $1.5 billion, and a tangible common equity to tangible assets ratio of less than 12%, excluding announced merger targets. The Skagit Peer Group consisted of the following companies:

March 31, 2018 or, if available, June 30, 2018, with pricing data as of July 24, 2018. The table below sets forth the data for Skagit and the high, low, mean and median data for the Skagit Peer Group.

Skagit Net Present Value Analyses

        Sandler O'Neill performed an analysis that estimated the net present value per share of Skagit common stock assuming Skagit performed in accordance with internal financial projections for the year ending December 31, 2018, as provided by the senior management of Skagit, as well as a long-term earnings per share growth rate and dividend payout ratio for the years thereafter, as directed by the senior management of Skagit. To approximate the terminal value of a share of Skagit common stock at December 31, 2022, Sandler O'Neill applied price to 2022 earnings per share multiples ranging from 14.0x to 24.0x and price to December 31, 2022 tangible book value per share multiples ranging from 140% to 215%. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 16.0% which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Skagit common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Skagit common stock of $202.45 to $415.73 when applying multiples of earnings per share and $178.55 to $328.56 when applying multiples of tangible book value per share.

        Sandler O'Neill also considered and discussed with the Skagit board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to projected net income. To illustrate this impact, Sandler O'Neill performed a similar analysis assuming Skagit's net income varied from 15% above projections to 15% below projections. This analysis resulted in the following range of per share values for Skagit common stock, applying the price to 2022 earnings per share multiples range of 14.0x to 24.0x referred to above and a discount rate of 12.68%.

        Sandler O'Neill noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Analysis of Selected Merger Transactions

        Sandler O'Neill reviewed a group of selected merger and acquisition transactions involving U.S. banks (which we refer to as the "Nationwide Precedent Transactions"). The Nationwide Precedent Transactions group consisted of bank transactions in the United States announced between January 1, 2017 and July 24, 2018 with disclosed deal values, target assets between $750 million and $1.5 billion and a target tangible common equity to tangible assets ratio of less than 12%.

        The Nationwide Precedent Transactions group was composed of the following transactions:

        Using the latest publicly available information prior to the announcement of the relevant transaction, Sandler O'Neill reviewed the following transaction metrics: transaction price to LTM earnings per share, transaction price to book value per share, transaction price to tangible book value per share and tangible book value premium to core deposits. Sandler O'Neill compared the indicated transaction multiples for the merger to the high, low, mean and median multiples of the Nationwide Precedent Transactions group.

Banner Comparable Company Analyses

        Sandler O'Neill used publicly available information as of March 31, 2018 unless otherwise noted, and information provided by Banner senior management as of June 30, 2018, to compare selected

financial information for Banner with a group of banks selected by Sandler O'Neill (which we refer to as the "Banner Peer Group"). The Banner Peer Group consisted of selected major exchange-traded banks headquartered in the western region of the United States with assets between $5 billion and $20 billion, excluding announced merger targets and excluding Cathay General Bancorp, Hanmi Financial Corporation, Hope Bancorp Inc., HomeStreet, Inc., Luther Burbank Corporation and Washington Federal, Inc. due to lack of similarity in business models and/or operating strategies of these companies when compared with Banner. The Banner Peer Group consisted of the following companies:

        The analysis compared financial information as of June 30, 2018 for Banner, as provided by Banner senior management, with corresponding publicly available data for the Banner Peer Group as of March 31, 2018, or if available, June 30, 2018, with pricing data as of July 24, 2018. The table below sets forth the data for Banner and the high, low, mean and median data for the Banner Peer Group.

Banner Stock Trading History

        Sandler O'Neill reviewed the historical stock price performance of Banner common stock for the one-year and three-year periods ended July 24, 2018. Sandler O'Neill then compared the relationship between the stock price performance of Banner's common stock to movements in the Banner Peer Group (as described above) as well as certain stock indices.

Banner Net Present Value Analyses

        Sandler O'Neill performed an analysis that estimated the net present value per share of Banner common stock assuming that Banner performed in accordance with publicly available consensus analyst net income estimates for Banner for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate for the years thereafter and dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Banner. To approximate the terminal value of Banner common stock at December 31, 2022, Sandler O'Neill applied price to 2022 earnings per share multiples ranging from 14.5x to 22.0x and price to December 31, 2022 tangible book value per share multiples ranging from 160% to 260%. The terminal values were then discounted to present values using different discount rates ranging from 7.0% to 13.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Banner common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Banner common stock of $46.71 to $84.50 when applying multiples of earnings per share and $45.35 to $86.98 when applying multiples of tangible book value per share.

        Sandler O'Neill also considered and discussed with the Skagit board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to net income. To illustrate this impact, Sandler O'Neill performed a similar analysis assuming Banner's net income varied from 15% above estimates to 15% below estimates. This analysis resulted in the following range of per share values for Banner common stock, applying the price to 2022 earnings per share multiples range of 14.5x to 22.0x referred to above and a discount rate of 9.69%.

        Sandler O'Neill noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Merger Analysis

        Sandler O'Neill analyzed certain potential pro forma effects of the merger. In performing this analysis, Sandler O'Neill utilized the following information and assumptions: (i) the merger closes on December 31, 2018; (ii) certain internal financial projections for Skagit for the year ending December 31, 2018, as provided by the senior management of Skagit, as well as a long-term earnings per share growth rate and dividend payout ratio for the years thereafter, as directed by the senior management of Skagit; (iii) publicly available consensus analyst net income estimates for Banner for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate for the years thereafter and dividend payout ratio for Banner for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Banner; and (iv) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as estimated revenue impacts following the closing of the merger, as directed by the senior management of Banner. The analysis indicated that the merger would be accretive to Banner's earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2019 through December 31, 2022, and dilutive to Banner's estimated tangible book at closing.

        In connection with this analysis, Sandler O'Neill considered and discussed with the Skagit board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted

that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Sandler O'Neill's Relationship

        Sandler O'Neill acted as Skagit's financial advisor in connection with the merger and will receive a fee for its services in an amount equal to 1.25% of the aggregate purchase price, which fee at the time of announcement was approximately $2.4 million and is contingent upon consummation of the merger. Sandler O'Neill also received a fee of $300,000 for rendering its opinion, which fairness opinion fee will be credited in full towards the transaction fee becoming due and payable to Sandler O'Neill on the day of closing of the merger. Skagit has also agreed to indemnify Sandler O'Neill against certain claims and liabilities arising out of Sandler O'Neill's engagement and to reimburse Sandler O'Neill for certain of its out-of-pocket expenses incurred in connection with Sandler O'Neill's engagement. In the two years preceding the date of Sandler O'Neill's opinion, Sandler O'Neill did not provide any other investment banking services to Skagit nor did Sandler O'Neill provide any investment banking services to Banner in the two years preceding the date thereof. In the ordinary course of Sandler O'Neill's business as a broker-dealer, Sandler O'Neill may purchase securities from and sell securities to Banner and its affiliates. Sandler O'Neill may also actively trade the equity and debt securities of Banner and its affiliates for Sandler O'Neill's own account and for the accounts of Sandler O'Neill's customers.

Certain Banner and Skagit Unaudited Prospective Financial Information

        Banner and Skagit do not, as a matter of course, publicly disclose forecasts or internal projections as to future performance, revenues, earnings, financial condition or other results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates. However, this proxy statement/prospectus contains certain limited unaudited prospective financial information for Banner and Skagit (which we refer to as the "projections") to give Skagit shareholders access to certain information provided to Banner and Skagit and their boards of directors, respectively, and the parties' respective financial advisors in connection with the merger.

        The projections were not prepared with a view toward public disclosure. As a result, the inclusion of the projections in this proxy statement/prospectus should not be regarded as an indication that Banner, Skagit or any other recipient of the projections considered, or now considers, them to be necessarily predictive of actual future results, or that it should be construed as financial guidance, and it should not be relied on as such. This information was prepared solely for internal use and is subjective in many respects. While presented with numeric specificity, the projections reflect numerous estimates and assumptions made with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to Banner's and Skagit's businesses, all of which are difficult to predict and many of which are beyond Banner's and Skagit's control. In addition, since the projections cover multiple years, such information by its nature becomes subject to greater uncertainty with each successive year.

        The projections also reflect assumptions as to certain business decisions that are subject to change. The projections reflect subjective judgment in many respects and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. As such, the projections constitute forward-looking information and are subject to risks and uncertainties that could cause actual results to differ materially from the results forecasted in such prospective information, including, but not limited to, Banner's performance, Skagit's performance, industry performance, general business and economic conditions, customer requirements, competition, adverse changes in applicable laws, regulations or rules, and the various risks set forth in Banner's reports filed with the SEC. For other factors that could cause the actual results to differ from the results forecasted in the projections, please see the sections entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in this proxy statement/prospectus.

        The projections were not prepared with a view toward complying with GAAP, the guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of financial information. Neither Moss Adams LLP, which serves as Banner's current independent registered public accounting firm and as Skagit's independent auditor, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the projections included below, or expressed any opinion or any other form of assurance on such information or its achievability.

        Furthermore, the projections do not take into account any circumstances or events occurring after the date they were prepared, including the transactions contemplated by the merger agreement or the possible financial and other effects of the merger (other than with respect to certain projections related to the surviving corporation set forth under "—Pro Forma Financial Analysis" below), and do not attempt to predict or suggest future results of the surviving corporation of the merger or give effect to the merger, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the potential synergies that may be achieved by Banner as a result of the merger, the effect on Banner or Skagit of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Neither Banner nor Skagit can give any assurance that, had the projections been prepared either as of the date of the merger agreement or as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. Further, the projections do not take into account the effect of any possible failure of the merger to occur. None of Banner, Skagit, Sandler O'Neill, D.A. Davidson & Co., Banner's financial advisor, which we refer to as "Davidson," nor any of their affiliates intends to, and each of them disclaims any obligation to, update, revise or correct the projections if they are or become inaccurate (even in the short term). The inclusion of the projections herein should not be deemed an admission or representation by Banner or Skagit that they are viewed by Banner or Skagit as material information of Banner or Skagit, respectively, particularly in light of the inherent risks and uncertainties associated with such projections. None of Banner, Skagit, Sandler O'Neill, Davidson or their respective representatives has made, makes or is authorized in the future to make any representation to any shareholder of Banner or Skagit or other person regarding Banner's or Skagit's ultimate performance compared to the information contained in the projections or that the forecasted results will be achieved. The projections included below are being provided because they were made available to and considered by Sandler O'Neill and Davidson and Skagit and Banner and their respective boards of directors in connection with the merger.

        In light of the foregoing, and considering that the special meeting will be held several months after the projections were prepared, as well as the uncertainties inherent in any forecasted information, Skagit shareholders are cautioned not to place unwarranted reliance on such information, and Skagit shareholders are urged to review Banner's most recent SEC filings and other documents incorporated herein by reference for a description of Banner's reported financial results and the financial information of Skagit included in this proxy statement/prospectus. See "Where You Can Find More Information."

Certain Projections Regarding Skagit

        Skagit provided to Sandler O'Neill and Sandler O'Neill used in its analysis, and Skagit provided to Banner and Davidson, an estimated earnings per share for Skagit of $18.97 for the year ending December 31, 2018, as well as an assumed long-term earnings per share growth rate of 7% for the years ending December 31, 2019 through December 31, 2022.

See the section entitled "The Merger Agreement—Conditions to Completion of the Merger" beginning on page 94 for a more complete description of the conditions that must be satisfied prior to closing. The date on which the closing occurs sometimes is referred to in this proxy statement/prospectus as the closing date.

        On the closing date, the parties will execute and file articles of merger with the Secretary of State of the State of Washington and a plan of merger. The merger will become effective at such time as designated in the articles of merger and plan of merger, or if no time is designated, at the time of filing of the articles of merger and plan of merger.

Interests of Directors and Executive Officers of Skagit in the Merger

        In considering the recommendation of the Skagit board of directors that you vote to approve the merger agreement, you should be aware that some of Skagit's directors and executive officers may have certain interests, including financial interests, in the merger that may be different from, or in addition

to, those of Skagit shareholders generally. The Skagit board of directors was aware of these interests, and considered them, among other matters, in reaching its decisions to approve the merger agreement and to recommend that you vote in favor of approving the merger agreement. See the sections entitled "The Merger—Background of the Merger" and "The Merger—Skagit's Reasons for the Merger; Recommendation of the Skagit Board of Directors." These interests are described in more detail below, and certain of them are quantified in the narrative below.

Voting and Support Agreements

        In connection with the execution of the merger agreement, Banner entered into voting and support agreements with the directors and executive officers of Skagit and/or their affiliates, in which each such person agreed, among other things, to vote the shares of Skagit common stock owned beneficially or of record by such person and over which such person has voting power in favor of the merger agreement and the proposal to adjourn or postpone the special meeting of the Skagit shareholders to a later date if there are not sufficient votes to approve the merger agreement, and against any alternative acquisition proposal or other action that would prevent, impede, interfere with, delay, postpone, discourage or frustrate the purposes of or adversely affect the consummation of the transactions contemplated by the merger agreement, as well as certain other restrictions with respect to the voting and transfer of such person's shares of Skagit common stock. The voting and support agreements entered into by non-management directors also include non-competition provisions pursuant to which such persons agree, for a period of two years from the closing of the merger, not to become involved with or serve a competing business that has a branch office or other office in, or does materially business in, any county in the State of Washington in which Skagit Bank or any banking subsidiary of Banner had commercial banking offices as of July 25, 2018 (which we refer to as a "competing business") or in any manner otherwise become involved in the organization, pre-opening phases, or formation of a competing business (other than using services of a competing business that are generally available to the public). Each of the voting and support agreements also contains non-solicitation provisions pursuant to which the applicable director or executive officer agrees (i) not to solicit or hire any employees of Banner, Skagit or any of their subsidiaries to participate in a competing business or to resign or terminate their employment with Banner, Skagit or any of their subsidiaries and (ii) not to solicit customers of Banner, Skagit or any of their subsidiaries to transfer their business to a competing business or to cease conducting business with Banner, Skagit or any of their subsidiaries. The voting and support agreements also contain provisions relating to the non-disclosure of confidential information of Banner, Skagit or any of their subsidiaries obtained by the shareholder while serving as a director, officer, employee or shareholder of Skagit or any of its subsidiaries.

        The voting and support agreements entered into by Cheryl R. Bishop, Skagit's Chief Executive Officer, Ken Johnson, Skagit's President and Chief Operating Officer, Richard C. Humphreys, Skagit's Chief Credit Officer, and Carla F. Tucker, Skagit's Chief Financial Officer, do not contain the non-competition provisions described above but do contain the provisions relating to non-solicitation and confidentiality described above.

        For more information regarding the voting and support agreements, see "The Merger Agreement—Voting and Support Agreements" beginning on page 98 and Annex D to this proxy statement/prospectus which contains a form of the voting and support agreements.

        A total of approximately 130,630 shares of Skagit common stock, or approximately 24.0% of the shares of Skagit common stock outstanding as of the record date for the special meeting, were subject to such voting and support agreements.

Treatment of Skagit Stock Options

        At the effective time of the merger, each Skagit option that is outstanding as of immediately prior to the effective time of the merger will fully vest and be canceled and converted into the right to receive a cash payment, without interest and less applicable withholding taxes, equal to the product of (i) the number of shares of Skagit common stock subject to the Skagit option as of immediately prior to the effective time of the merger and (ii) the excess, if any, of (1) the product of the exchange ratio and the Banner average closing price over (2) the exercise price per share of Skagit common stock subject to such Skagit option as of the effective time of the merger.

        None of Skagit's four executive officers is expected to hold any unvested equity awards as of the closing date.

Change in Control Agreements

        Skagit Bancorp and Skagit Bank (either and/or both being referred to as the "Company" for purposes of the following discussion) have previously entered into change in control severance agreements with each of Skagit's executive officers.

        The agreements provide that, if the Company terminates the executive officer's employment without "cause" or the executive officer resigns for "good reason" (each as defined in the applicable agreement) and, within 18 months thereafter, the Company enters into an agreement providing for a change in control or any party announces or is required to announce a prospective change in control, which change in control is consummated, then the Company will pay the executive officer a single cash payment in an amount equal to two times the greater of (a) the highest compensation received by the executive officer during any of the most recent three calendar years, and (b) 130% of the executive officer's base compensation as of the date of termination of employment.

        In addition, if a change in control is consummated while the executive officer is employed by the Company, then, upon the closing of such change in control (regardless of whether the executive officer continues his or her employment with the acquiring company), the Company will pay the executive officer a single cash payment in an amount equal to two times the greater of (a) the highest compensation received by the executive officer during any of the three most recent calendar years, and (b) 130% of the executive officer's base compensation as of the date on which the closing occurs.

        The agreements provide that, if payments under the agreements, together with any other payments or benefits received by the executive officer from the Company or the acquiring company, would cause such agreement payments to be "parachute payments" (within the meaning of the Code), then such agreement payments will be reduced so that no agreement payments constitute "parachute payments."

        Quantification of Payments.    The estimated aggregate amount that would be payable to Skagit's four executive officers if the effective time occurred on August 21, 2018 under their change in control severance agreements is $3,016,159.

Prorated Bonuses

        Under the merger agreement, Skagit Bank is entitled to pay prorated awards under the annual or quarterly cash incentive plans of Skagit Bank as of the closing for the 12-month or 3-month, respectively, period in which the closing occurs to the extent such amounts are accrued in the final closing statement delivered under the merger agreement and Skagit's financial statements in the ordinary course of business, consistent with past practice.

        Quantification of Payments.    The estimated aggregate amount that would be payable to Skagit's four executive officers (based on target performance) if the effective time were to occur on August 21, 2018 is $183,970.

Prorated 401(k) Plan Contributions

        Under the merger agreement, Skagit Bank is entitled to make prorated matching and profit-sharing contributions to Skagit Bank's 401(k) plan for the year in which the closing occurs immediately prior to the closing for all participants in the plan to the extent such amounts are accrued in the final closing statement delivered under the merger agreement and Skagit's financial statements in the ordinary course of business, consistent with past practice.

        Quantification of Payments.    The estimated aggregate amount that would be contributed to Skagit Bank's 401(k) plan for the benefit of Skagit's four executive officers if the effective time were to occur on August 21, 2018 is $42,132.

Cheryl R. Bishop Service on Banner Board

        The merger agreement provides that effective immediately following the closing of the merger, Banner will take such actions as are necessary to appoint Cheryl R. Bishop to the board of directors of Banner.

Indemnification and Insurance

        As described under "The Merger Agreement—Indemnification and Insurance," the merger agreement provides that, for a period of six (6) years from and after the effective time of the merger, to the fullest extent permitted by applicable law, the surviving corporation will indemnify and hold harmless, to the extent such persons are indemnified as of July 25, 2018 by Skagit pursuant to Skagit's articles of incorporation and bylaws, or pursuant to certain indemnification agreements in effect on July 25, 2018, and will also advance expenses as incurred to the extent provided under Skagit's articles of incorporation and bylaws (or such indemnification agreements), each present and former director and officer of Skagit and its subsidiaries (in each case, when acting in such capacity) against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the effective time of the merger, arising out of the fact that such person is or was a director or officer of Skagit or any of its subsidiaries and pertaining to matters existing or occurring at or prior to the effective time of the merger, including the transactions contemplated by the merger agreement, subject to such person providing an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

        The merger agreement requires that, for a period of six (6) years after the effective time of the merger, the surviving corporation maintain Skagit's existing directors' and officers' liability insurance policies, or policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured, with respect to claims arising from facts or events which occurred at or before the effective time of the merger. However, the surviving corporation is not required to expend, on an annual basis, an amount in excess of 250% of the current annual premium paid as of July 25, 2018 by Skagit for such insurance, which we refer to as the "premium cap," and if such premiums for such insurance would at any time exceed that amount, then the surviving corporation will maintain policies of insurance which, in the surviving corporation's good faith determination, provide the maximum coverage available at an annual premium not exceeding the premium cap. In lieu of the foregoing, Banner or Skagit, in consultation with, but only upon the consent of Banner (which consent may not be unreasonably withheld, conditioned or delayed), may (and at the request of Banner, Skagit will) obtain at or prior to the effective time of the merger a six-year "tail" policy under Skagit's existing directors' and officers' liability insurance policy providing equivalent coverage to that described above, if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the premium cap.

The Banner Board of Directors After the Merger

        The merger agreement provides that effective immediately following the effective time of the merger, Banner will appoint Cheryl R. Bishop, Skagit's Chief Executive Officer, to serve on the Banner board of directors.

        Ms. Bishop, 69, has been a director of Skagit and Skagit Bank since 2006 and 1991, respectively. She was appointed Chief Executive Officer of Skagit Bank in 2004 and Chief Executive Officer of Skagit in 2006. She also served as President of Skagit Bank from 2006 to 2015. Ms. Bishop began her career with Skagit Bank in September 1971 as Operations Officer and teller, and held a variety of positons with Skagit Bank prior to becoming Chief Executive Officer. Ms. Bishop provides extensive community banking experience and expertise. Ms. Bishop is active in the communities Skagit serves and has served on the boards of various banking professional associations. She currently serves on the board of the Washington Bankers Association.

Regulatory Approvals

        Completion of the merger and the bank merger are subject to the receipt of all approvals and/or waivers required to complete the transactions contemplated by the merger agreement, including from the Federal Reserve Board, the FDIC, and the DFI. Notifications and/or applications requesting approval may also be submitted to various other federal and state regulatory authorities and self-regulatory organizations.

        Although we currently believe that we should be able to obtain all required regulatory approvals and/or waivers in a timely manner, we cannot be certain when or if we will obtain them or, if obtained, whether they will contain terms, conditions or restrictions not currently contemplated that will be detrimental to Banner after the completion of the merger or will constitute a materially burdensome regulatory condition for purposes of the merger agreement.

        On August 16, 2018, Banner requested a waiver of the approval requirement with the Federal Reserve Board, and, on August 27, 2018, the Federal Reserve Board approved that waiver request. On August 16, 2018, Banner Bank and Skagit Bank filed the required applications with the FDIC and the DFI.

        Federal Reserve Board.    Completion of the merger is subject, among other things, to approval by the Federal Reserve Board pursuant to Section 3 of the Bank Holding Company Act, which we refer to as the "BHC Act," unless the Federal Reserve Board waives that requirement. On August 16, 2018, Banner requested a waiver of this prior approval requirement using procedures outlined in applicable regulations to confirm that an application and approval is not required under Section 3 of the BHC Act. On August 27, 2018, the Federal Reserve Board approved that waiver request. Accordingly, no application to the Federal Reserve is required under Section 3 of the BHC Act.

        Federal Deposit Insurance Corporation.    The prior approval of the FDIC is required under the federal Bank Merger Act to merge Skagit Bank with and into Banner Bank. In evaluating an application filed under the Bank Merger Act, the FDIC generally considers: (i) the competitive impact of the transaction; (ii) financial and managerial resources of the banks party to the bank merger; (iii) the convenience and needs of the community to be served and the record of the banks under the Community Reinvestment Act of 1977, which we refer to as the "CRA," including their CRA performance ratings; (iv) the banks' effectiveness in combating money-laundering activities; and (v) the extent to which the bank merger would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. In connection with its review, the FDIC provides an opportunity for public comment on the application and is authorized to hold a public meeting or other proceeding if it determines that would be appropriate.

        Banner Bank and Skagit Bank each received an overall "satisfactory" CRA performance rating in their most recent respective CRA performance examinations, as did Islanders Bank, another wholly owned banking subsidiary of Banner.

        The Bank Merger Act and FDIC regulations require published notice of, and the opportunity for public comment on, the application to the FDIC and authorize the FDIC to hold a public hearing or meeting if the FDIC determines that a hearing or meeting would be appropriate. The FDIC takes into account the views of third-party commenters, particularly on the subject of the merging parties' service to their communities, and any hearing, meeting or comments provided by third parties could prolong the period during which the application is under review by the FDIC.

        Transactions approved by the FDIC generally may not be completed until thirty (30) days after the approval of the FDIC is received, during which time the Department of Justice, which we refer to as the "DOJ," may challenge the transaction on antitrust grounds. With the approval of the FDIC and the concurrence of the DOJ, the waiting period may be reduced to no less than fifteen (15) days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the merger, the DOJ could analyze the merger's effect on competition differently than the FDIC, and thus it is possible that the DOJ could reach a different conclusion than the FDIC does regarding the merger's effects on competition. A determination by the DOJ not to object to the merger may not prevent the filing of antitrust actions by private persons or state attorneys general.

        Washington State Department of Financial Institutions, Division of Banks.    The bank merger is subject to and must comply with the requirements of the Revised Code of Washington, which we refer to as the "RCW." Under Section 30A.49 of the RCW, notice of the bank merger must be provided to the DFI along with a copy of the Bank Merger Act application filed with the FDIC. Under Section 30A.49 of the RCW, the Director of the Banks shall approve the notice if it appears that: (1) the resulting state bank (which in this case would be Banner Bank) meets the requirements of state law as to the formation of a new state bank; and (2) the agreement between the banks (i) provides an adequate capital structure, (ii) is fair and (iii) is not contrary to the public interest. If the Director of Banks disapproves an agreement, then he or she shall state his or her objections and give an opportunity to the bank to amend the agreement to obviate such objections.

        Additional Regulatory Approvals and Notices.    Notifications and/or applications requesting approval of the merger and/or the bank merger may be submitted to various other federal and state regulatory authorities and self-regulatory organizations. However, Skagit and Banner are not currently aware of any other material governmental approvals or actions that are required prior to the parties' completion of the merger.

        Shareholders should note that the approval of any notice or application merely implies satisfaction of regulatory criteria for approval, and does not include review of the merger from the standpoint of the adequacy of the consideration to be received by, or fairness to, shareholders. Regulatory approval does not constitute an endorsement or recommendation of the proposed merger.

        Skagit and Banner believe that the proposed merger does not raise substantial antitrust or other significant regulatory concerns and that we will be able to obtain all requisite regulatory approvals, although Skagit and Banner cannot provide any assurance as to whether the requisite regulatory approvals will be obtained, and, if obtained, as to the date of receipt of any of these approvals, the terms thereof or the absence of any litigation challenging them. There can be no assurance that the regulatory approvals discussed above will be received on a timely basis or at all, or as to the ability of Banner and Skagit to obtain the approvals on satisfactory terms or as to the absence of litigation challenging such approvals.

Accounting Treatment

        Banner prepares its financial statements in accordance with GAAP. The merger will be accounted for using the acquisition method of accounting. Banner will be treated as the acquirer for accounting purposes.

NASDAQ Market Listing

        The shares of Banner common stock to be issued in the merger will be listed for trading on the NASDAQ.

Dividends/Distributions

        From and after July 25, 2018, the date of the merger agreement, Skagit may not, and may not permit its subsidiaries to, without the prior written consent of Banner, make, declare or pay or set a record date for any dividend or any other distribution on any shares of its capital stock or other equity or voting securities or certain other securities of Skagit or its subsidiaries other than (i) dividends paid by any subsidiary of Skagit to Skagit or by Skagit to any wholly owned subsidiary of Skagit, (ii) quarterly dividends at a rate not in excess of $1.50 per share of Skagit common stock, (iii) a special cash dividend that the board of directors of Skagit may declare and pay immediately prior to the closing in the event Skagit's adjusted shareholders' equity, as finally determined pursuant to the merger agreement, exceeds $80 million, in an amount not to exceed such excess and (iv) the acceptance of Skagit common stock as payment for the exercise price of Skagit options or for withholding taxes incurred in connection with the exercise of Skagit options or the vesting or settlement of Skagit equity awards outstanding as of July 25, 2018, in each case, in accordance with past practice and the terms of the applicable award agreements as in effect on July 25, 2018.

        No dividends or other distributions declared or made with respect to Banner common stock will be paid to the holder of any unsurrendered certificate or book entry share that evidenced ownership of shares of Skagit common stock until such holder properly surrenders such shares. See the section entitled "The Merger Agreement—Exchange and Payment Procedures" beginning on page 81 of this proxy statement/prospectus.

Dissenters' Rights

        In accordance with Chapter 13 of the WBCA, Skagit shareholders have the right to dissent from the merger and to receive payment in cash for the "fair value" of their Skagit common stock. Skagit shareholders should recognize that "fair value" of their Skagit common stock as determined pursuant to Chapter 13 of the WBCA could be higher, lower or the same as the merger consideration.

        Skagit shareholders electing to exercise dissenters' rights must comply with the provisions of Chapter 13 of the WBCA in order to perfect their rights. Skagit and Banner will require strict compliance with the statutory procedures. If a Skagit shareholder fails to meet any of the requirements for assertion of dissenters' rights, such shareholder will not be entitled to payment in cash for the "fair value" for such shareholder's shares under the WBCA. The following is intended as a brief summary of the material provisions of the Washington statutory procedures required to be followed by a Skagit shareholder in order to dissent from the merger and perfect the shareholder's dissenters' rights. This summary, however, is not a complete statement of all applicable requirements and is qualified in its entirety by reference to Chapter 13 of the WBCA, the full text of which is set forth in Annex C.

        A shareholder who wishes to assert dissenters' rights must (i) deliver to Skagit before the vote of Skagit shareholders is taken notice of the shareholder's intent to demand payment for the shareholder's shares if the merger is effected, and (ii) not vote such shares in favor of the approval of the merger

74

agreement. A shareholder wishing to deliver such notice should hand deliver or mail such notice to Skagit at the following address prior to the special meeting:

Nancy K. Galbreath, Executive Assistant to the CEO
Skagit Bancorp, Inc.
301 East Fairhaven Avenue
Burlington, Washington 98233
(360) 755-0411

or deliver such notice at the special meeting prior to the vote being taken by Skagit shareholders.

        A shareholder who wishes to exercise dissenters' rights generally must dissent with respect to all the shares the shareholder owns or over which the shareholder has power to direct the vote. However, if a record shareholder is a nominee for multiple beneficial shareholders some of whom wish to dissent and some of whom do not, then the record holder may dissent with respect to all the shares beneficially owned by any one person by delivering to Skagit a notice of the name and address of each person on whose behalf the record shareholder asserts dissenters' rights. A beneficial shareholder may assert dissenters' rights directly by submitting to Skagit the record shareholder's written consent and by dissenting with respect to all the shares of which such shareholder is the beneficial shareholder or over which such shareholder has power to direct the vote.

        A shareholder who does not deliver to Skagit prior to the vote being taken by Skagit shareholders a notice of the shareholder's intent to demand payment for the "fair value" of the shares will lose the right to exercise dissenters' rights. In addition, any shareholder electing to exercise dissenters' rights must either vote against the approval of the merger agreement or abstain from voting. Submitting a properly signed proxy card that is received prior to the vote at the special meeting (and is not properly revoked) that does not direct how the shares of Skagit common stock represented by proxy are to be voted will constitute a vote in favor of the approval of the merger agreement and a waiver of such shareholder's statutory dissenters' rights.

        If the merger agreement is approved at the special meeting and the merger is effected, Banner as the surviving corporation will, within ten (10) days after the effective date of the merger, deliver a written notice to all shareholders who properly perfected their dissenters' rights in accordance with Chapter 13 of the WBCA. Such notice will: (i) state where the payment demand must be sent and where and when certificates for certificated shares must be deposited; (ii) inform holders of uncertificated shares to what extent transfer of the shares will be restricted after the payment demand is received; (iii) supply a form for demanding payment that includes the date of the first announcement to news media or to shareholders of the terms of the proposed transaction and requires that the person asserting dissenters' rights certify whether or not the person acquired beneficial ownership of the shares before that date; (iv) set a date by which Banner must receive the payment demand, which date will be between thirty (30) and sixty (60) days after notice is delivered; and (v) be accompanied by a copy of Chapter 13 of the WBCA.

        A shareholder wishing to exercise dissenters' rights must timely file the payment demand, certify whether the shareholder acquired beneficial ownership of the shares before the date of the first announcement to news media or to shareholders of the merger, and deposit share certificates as required in the notice. Failure to do so will cause such person to lose his or her dissenters' rights.

        Within thirty (30) days after the effective time of the merger or receipt of the payment demand, whichever is later, Banner will pay each dissenter with properly perfected dissenters' rights Banner's estimate of the "fair value" of the shareholder's interest, plus accrued interest from the effective date of the merger. With respect to a dissenter who did not beneficially own Skagit shares before the date of the first announcement to news media or to shareholders of the merger, Banner is not required to make the payment until after the dissenter has agreed to accept the payment in full satisfaction of the

75

Table of Contents

dissenter's demands. "Fair value" means the value of the shares immediately before the effective date of the merger, excluding any appreciation or depreciation in anticipation of the merger unless such exclusion would be inequitable. The rate of interest is generally required to be the average rate currently paid by Banner on its principal bank loans or, if none, at a rate that is fair and equitable under the circumstances. Shareholders should note that investment banker opinions as to the fairness, from a financial point of view, of the consideration payable in a transaction such as the merger are not opinions as to, and do not address in any respect, fair value under Chapter 13 of the WBCA.

        A dissenter who is dissatisfied with Banner's estimate of the fair value or believes that interest due is incorrectly calculated may notify Banner of the dissenter's estimate of the fair value and amount of interest due within thirty (30) days after Banner makes or offers payment for the dissenter's shares. If Banner does not accept the dissenter's estimate and the parties do not otherwise settle on a fair value then Banner must, within sixty (60) days, petition a court to determine the fair value or pay each dissenter whose demand remains unsettled the amount demanded.

        Banner must make all dissenters whose demands remain unsettled parties to the proceeding. Each dissenter made a party to such proceeding is entitled to judgment for the amount, if any, by which the court finds the fair value of the dissenter's shares, plus interest, exceeds the amount paid by Banner, or the fair value, plus accrued interest, of the dissenter's after-acquired shares for which Banner elected to withhold payment.

        The court will determine all costs of such proceeding and will assess such costs against Banner, including the reasonable compensation and expenses of appraisers appointed by the court, except that the court may assess the costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding payment under Chapter 13 of the WBCA. The court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

•

against Banner and in favor of any or all dissenters if the court finds Banner did not substantially comply with the requirements of Chapter 13 of the WBCA; or



•

against either Banner or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by Chapter 13 of the WBCA.

        If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated, and that the fees for those services should not be assessed against Banner, the court may award to these counsel reasonable fees to be paid out of the amounts awarded to dissenters who were benefited.

        In view of the complexity of Chapter 13 of the WBCA and the requirement that shareholders must strictly comply with such statutory procedures, shareholders who wish to exercise dissenters' rights should consult their legal and financial advisors. There can be no assurance that "fair value" of any such shareholder's Skagit common stock as determined pursuant to Chapter 13 of the WBCA will be greater than or equal to the merger consideration.

THE MERGER AGREEMENT

        This section describes the material terms of the merger agreement. The description in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached as Annex A and is incorporated by reference into this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. You are encouraged to read the merger agreement carefully and in its entirety. This section is not intended to provide you with any factual information about Skagit or Banner. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings Banner makes with the SEC, as described in the section entitled "Where You Can Find More Information" beginning on page 120 of this proxy statement/prospectus.

Explanatory Note Regarding the Merger Agreement

        The merger agreement and this summary of terms are included to provide you with information regarding the terms of the merger agreement. Factual disclosures about Skagit and Banner contained in this proxy statement/prospectus or in the public reports of Banner filed with the SEC may supplement, update or modify the factual disclosures about Skagit and Banner contained in the merger agreement. The merger agreement contains representations and warranties by Skagit, on the one hand, and by Banner, on the other hand, made solely for the benefit of the other. The representations, warranties and covenants made in the merger agreement by Skagit and Banner were qualified and subject to important limitations agreed to by Skagit and Banner in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC, and some were qualified by the matters contained in the confidential disclosure schedules that Skagit and Banner each delivered in connection with the merger agreement and certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement. Accordingly, the representations and warranties in the merger agreement should not be relied on by any persons as characterizations of the actual state of facts about Skagit or Banner at the time they were made or otherwise.

Merger Consideration

        At the effective time of the merger, each outstanding share of Skagit common stock, other than certain shares held by Banner or Skagit (in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity or as a result of debts previously contracted) or by a Skagit shareholder who properly exercises dissenters' right when and in the manner required under Chapter 23B.13 of the WBCA, will be converted into the right to receive 5.6664 shares of Banner common stock, subject to the adjustment described below.

Potential Adjustment to Exchange Ratio

        Not later than five (5) days after each month-end during the period from the date of the merger agreement until the final closing statement is delivered to Banner as described below, Skagit will, in consultation with Banner and consistent with past practice, prepare in good faith and deliver to Banner

Table of Contents

(i) Skagit's consolidated financial statements presenting the financial condition of Skagit and its subsidiaries on a consolidated basis as of the close of business on the last day of such month-end and Skagit's and its subsidiaries' consolidated results of operations for the period from January 1, 2018 through the close of business on the last day of such month-end and (ii) a statement setting forth adjusted shareholders' equity as if such month-end were the shareholders' equity measuring date (each as defined below) (we refer to each such statement as an "interim closing statement"). Each interim closing statement will be prepared in accordance with GAAP and other applicable legal and accounting requirements, and reflect all period-end accruals and other adjustments and will also reflect accruals for all transaction costs or other liabilities incurred or expected to be incurred at any time at or prior to the closing, including in connection with the transactions contemplated by the merger agreement (whether or not doing so is in accordance with GAAP).

        Not later than five (5) days after the end of the month preceding the month that includes the anticipated closing date (as reasonably agreed in good faith by Banner and Skagit), Skagit will, in consultation with Banner, prepare in good faith and deliver to Banner an updated interim closing statement as of and through the close of business on the last day of the month-end immediately preceding the anticipated closing date prepared in a manner consistent with the interim closing statements (such statement as it may be adjusted in accordance with the merger agreement is referred to as the "final closing statement"); provided, however, that if the anticipated closing date is in the first eight (8) days of a calendar month, then the final closing statement will be prepared as of the month-end of the second month preceding the anticipated closing date (we refer to the date which the final closing statement is as of and through as the "shareholders' equity measuring date"). Skagit must also deliver to Banner a certificate of Skagit's chief financial officer, dated as of the closing date, to the effect that the financial statements set forth in the final closing statement continue to reflect accurately, as of the closing date, the financial condition of Skagit and its subsidiaries in all material respects and meet the requirements of the merger agreement.

        Banner will have the right to review, and have reasonable access to, all relevant books and records, work papers, schedules, memoranda and other documents prepared by Skagit or its subsidiaries or its and their respective accountants in connection with its preparation of the interim closing statements and the final closing statement, as well as to executive, finance and accounting personnel of Skagit and its subsidiaries and any other information which Banner may reasonably request in connection with its review, and Skagit and its subsidiaries and its and their accountants and other representatives will cooperate with and assist Banner and its accountants and other representatives in the review of the interim closing statements and the final closing statement. In the event Banner disputes the final closing statement (including adjusted shareholders' equity set forth therein), Banner will, no later than the later of (i) three (3) days after receiving the final closing statement and (ii) two (2) days prior to the anticipated closing date, give Skagit written notice of its objections, which we refer to as an "objection notice," describing the nature of the dispute in reasonable detail and specifying those items and amounts as to which Banner disagrees and, based on the information at its disposal, specifying Banner's proposed calculation of adjusted shareholders' equity. If Banner does not timely deliver an objection notice, adjusted shareholders' equity set forth in the final closing statement delivered by Skagit will be utilized for the calculation of the adjustment to the exchange ratio described below and will be final and binding on all the parties.

        If Banner timely delivers an objection notice, Banner and Skagit will cooperate in good faith to resolve such dispute, and if resolved, the final closing statement and adjusted shareholders' equity as determined by Banner and Skagit in writing will be utilized for calculation of the adjustment to the exchange ratio described below and will be final and binding on all the parties. If Banner and Skagit cannot resolve the dispute within five (5) days after the date of the objection notice, Banner and Skagit will appoint a mutually acceptable independent accounting firm of national or regional reputation, which we refer to as the "independent accounting firm," to promptly review the merger agreement and

78

Table of Contents

the disputed items in the objection notice and arbitrate the dispute and determine the final closing statement and adjusted shareholders' equity. The independent accounting firm will be given reasonable access to all records, work papers, schedules, memoranda and other documents relevant to such dispute and will be limited to addressing only the particular disputes referred to in the objection notice that have not been resolved by Banner and Skagit and will determine such disputed amounts, the final closing statement and adjusted shareholders' equity in accordance with the provisions of the merger agreement. Upon reaching its determination of the final closing statement and adjusted shareholders' equity based on its determination of the disputed items, the independent accounting firm will deliver a copy of its calculation of the final closing statement and adjusted shareholders' equity to Banner and Skagit. The determination of the independent accounting firm will be made within twenty (20) days after its engagement and will be final and binding on all the parties. No party or its affiliates may seek further recourse to courts, other tribunals or otherwise, other than to enforce the final decision of the independent accounting firm as to the determination of the final closing statement and adjusted shareholders' equity. The aggregate fees, expenses and costs of the independent accounting firm will be borne (i) by Banner, if the difference, in absolute value terms, between adjusted shareholders' equity as finally determined and adjusted shareholders' equity set forth in the objection notice is greater than the difference, in absolute value terms, between adjusted shareholders' equity as finally determined and adjusted shareholders' equity set forth in the final closing statement as delivered by Skagit to Banner and (ii) otherwise by Skagit, in the form of a reduction to adjusted shareholders' equity for purposes of calculating the adjustment to the exchange ratio described below.

        The merger consideration will be reduced, via a downward adjustment to the exchange ratio of 5.6664, on a dollar-for-dollar basis (based on the average closing price of Banner common stock on the NASDAQ for the consecutive period of the five (5) full trading days immediately preceding (but not including) the date that is the second (2nd) business day prior to the closing date, which we refer to as the "Banner average closing price"), if adjusted shareholders' equity is less than $80 million. Specifically, if adjusted shareholders' equity, as finally determined pursuant to the merger agreement, is less than $80 million (we refer to the difference between $80 million and such adjusted shareholders' equity as the "shareholders' equity shortfall"), the exchange ratio will be reduced by an amount, rounded to the ten-thousandth decimal point, equal to (i) the shareholders' equity shortfall divided by (ii) the number of shares of Skagit common stock issued and outstanding immediately prior to the effective time of the merger (other than certain shares held by Banner or Skagit which are not converted into the right to receive merger consideration), divided by (iii) the Banner average closing price. If adjusted shareholders' equity, as finally determined pursuant to the merger agreement, is equal to or exceeds $80 million, there will be no adjustment to the exchange ratio, and Skagit may declare and pay a special cash dividend to its shareholders immediately prior to the closing in an amount not to exceed such excess.

        For purposes of the merger agreement, "adjusted shareholders' equity" means the consolidated shareholders' equity of Skagit as set forth in the final closing statement prepared as of and through the shareholders' equity measuring date minus any declared but unpaid dividends as of the shareholders' equity measuring date (or thereafter declared), plus the sum of (i) all fees and expenses of all attorneys, accountants, investment bankers and other advisors and agents for Skagit for services rendered in connection with the transactions contemplated by the merger agreement, (ii) any employee severance, retention or change-in-control payments or expenses consistent with the terms of the merger agreement, (iii) any payment made or expense accrued for the purchase of a directors' and officers' liability insurance policy pursuant to the merger agreement, and (iv) other third-party costs, fees and expenses in an aggregate amount not to exceed $50,000, in each case of clauses (i)-(iv) specifically incurred or accrued by Skagit in connection with the transactions contemplated by the merger agreement, and in each case, paid by Skagit or payable by Skagit prior to the effective time of the merger to the extent reflected as accrued liabilities in the final closing statement.

Table of Contents

        Set forth below is a table showing the hypothetical exchange ratios and hypothetical implied values of the merger consideration based on a range of hypothetical adjusted shareholders' equity values, and assuming (i) a Banner average closing price of either (x) $61.60, the closing price per share of Banner common stock on July 25, 2018, the last trading day before the announcement of the merger agreement, or (y) $64.96, the closing price per share of Banner common stock on September 4, 2018, the last practicable trading day before the date of this proxy statement/prospectus and (ii) that the number of shares of Skagit common stock issued and outstanding immediately prior to the effective time of the merger (other than certain shares held by Banner or Skagit which are not converted into the right to receive merger consideration) is 544,257, the number of shares of Skagit common stock issued and outstanding as of July 25, 2018.

        If, prior to the effective time of the merger, the outstanding shares of Banner common stock or Skagit common stock are increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split, an appropriate and proportionate adjustment will be made to the exchange ratio and the merger consideration to give Skagit shareholders and Banner the same economic effect as contemplated by the merger agreement prior to such event.

        Based on the number of shares of Banner common stock and shares of Skagit common stock outstanding as of September 4, 2018, the last date before the date of this proxy statement/prospectus for which it was practicable to obtain this information, we expect that Skagit shareholders as of immediately prior to the closing of the merger will hold, in the aggregate, approximately 8.7% of the issued and outstanding shares of Banner common stock immediately following the closing of the merger (without giving effect to any shares of Banner common stock held by Skagit shareholders prior to the merger or any potential adjustment to the exchange ratio).

Fractional Shares

        Banner will not issue any fractional shares of Banner common stock in the merger. In lieu of the issuance of any such fractional share, Banner will pay to each Skagit shareholder who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the Banner average closing price by (ii) the fraction of a share (after taking into account all shares of Skagit common stock held by such holder immediately prior to the effective time of the merger and rounded to the nearest one-thousandth when expressed in decimal form) of Banner common stock to which such holder would otherwise be entitled to receive pursuant to the merger agreement.

Effect of the Merger; Effective Time of the Merger; Organizational Documents of the Surviving Corporation

Effect of the Merger

        The merger agreement provides for the merger of Skagit with and into Banner, with Banner surviving the merger as the surviving corporation. We sometimes refer to Banner following the merger as the "surviving corporation."

        As a result of the merger, Skagit shareholders will only participate in the surviving corporation's future earnings and potential growth through their ownership of Banner common stock. All of the other incidents of direct ownership of Skagit common stock, such as the right to vote on certain corporate decisions, to elect directors and to receive dividends and distributions from Skagit, will be extinguished upon completion of the merger. All of the properties, rights, privileges, powers and franchises of Skagit will vest in the surviving corporation, and all debts, duties and liabilities of Skagit will become the debts, liabilities and duties of the surviving corporation.

        Under the merger agreement, Banner is empowered to, at any time prior to the effective time of the merger, change the method or structure of effecting the combination of Skagit and Banner. However, that no such change or amendment may (i) alter or change the amount or kind of the merger consideration, (ii) adversely affect the tax treatment of the merger with respect to either party or its shareholders or (iii) impede or materially delay the consummation of the transaction or the receipt of the requisite regulatory approvals.

Closing; Effective Time of the Merger

        The closing of the merger will take place at 10:00 a.m. Seattle time, on a date no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in the merger agreement (other than those conditions that by their nature can only be satisfied at the closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by Banner and Skagit. The date on which the closing occurs is referred to as the "closing date."

        On the closing date, the parties will execute and file articles of merger with the Secretary of State of the State of Washington and a plan of merger. The merger will become effective at such time as designated in the articles of merger and plan of merger, or if no time is designated, at the time of filing of the articles of merger and plan of merger, which we refer to as the "effective time of the merger."

Organizational Documents of the Surviving Corporation

        The amended and restated articles of incorporation and bylaws of Banner, as in effect immediately prior to the effective time of the merger, will be the articles of incorporation and bylaws of the surviving corporation until duly amended in accordance with their respective terms and applicable law. The surviving corporation will continue to exist under the name "Banner Corporation."

Exchange and Payment Procedures

        At or prior to the effective time of the merger, Banner will deposit, or cause to be deposited, with an exchange agent designated by Banner and reasonably acceptable to Skagit, for the benefit of Skagit shareholders, Banner common stock and any cash in lieu of fractional shares to be delivered to Skagit shareholders pursuant to the merger agreement, which amounts we refer to as the "exchange fund." As promptly as practicable after the effective time of the merger, but in no event later than five (5) business days thereafter, Banner will cause the exchange agent to mail to each record holder, as of immediately prior to the effective time of the merger, of shares of Skagit common stock that are

81

Table of Contents

converted into the right to receive the merger consideration at the effective time of the merger, a letter of transmittal for use in connection with the exchange and instructions for use in surrendering the applicable certificates or book entry shares in exchange for the merger consideration. The letter of transmittal will specify that delivery will be effected, and risk of loss and title to certificates of Skagit common stock will pass, only upon proper delivery of the certificates to the exchange agent.

        You should not send in your certificates until you receive the letter of transmittal and instructions.

        Skagit shareholders who properly surrender their certificates or book entry shares to the exchange agent, accompanied by a properly completed and duly executed letter of transmittal will receive for each Skagit share the stock consideration plus any cash payable in lieu of any fractional shares of Banner, and any dividends or distributions such holder has the right to receive pursuant to the merger agreement. No interest will be paid or accrue on any merger consideration, dividends or distributions or cash in lieu of fractional shares.

Distributions with Respect to Unsurrendered Shares

        No dividends or other distributions declared with respect to Banner common stock will be paid to the holder of any unsurrendered certificate or book entry share that evidenced ownership of shares of Skagit common stock until such holder surrenders such shares. After such surrender, the record holder will be entitled to receive any dividends or other distributions, without interest, that have been become payable with respect to the holder's whole shares of Banner common stock.

Transfers Following the Effective Time of the Merger

        After the effective time of the merger, there will be no transfers on the stock transfer books of Skagit of the shares of Skagit common stock that were issued and outstanding immediately prior to the effective time of the merger. If, after the effective time of the merger, any such certificates or book entry shares are presented for transfer to the exchange agent, they will be canceled and exchanged for the merger consideration as provided in the merger agreement.

Termination of Exchange Fund

        Any portion of the exchange fund that remains unclaimed by Skagit shareholders for six (6) months after the effective time of the merger will be delivered to the surviving corporation. From and after such time, any former holders of Skagit common stock who have not exchanged their shares may thereafter look only to the surviving corporation for payment of the merger consideration, cash in lieu of any fractional shares and any unpaid dividends and distributions on the Banner common stock such holder has the right to receive pursuant to the merger agreement. None of Banner, Skagit, the surviving corporation nor the exchange agent, nor any other person, will be liable to any former holder of Skagit common stock for any amount delivered in good faith to a public official pursuant to abandoned property, escheat or similar laws.

Lost, Stolen or Destroyed Stock Certificates

        If any certificate representing shares of Skagit common stock is lost, stolen or destroyed, upon the making of an affidavit of such fact by the person claiming the certificate to be lost, stolen or destroyed and, if reasonably required by Banner or the exchange agent, the posting by such person of a bond in such amount as Banner or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such certificate, the exchange agent will issue in exchange for such lost, stolen or destroyed certificate the merger consideration, any cash in lieu of fractional shares, and any dividends or distributions to which such holder is entitled pursuant to the merger agreement.

Withholding Rights

        Banner will be entitled to deduct and withhold, or cause the exchange agent to deduct and withhold, from any amounts payable pursuant to the merger agreement to any holder of Skagit common stock or Skagit equity awards such amounts as it is required to deduct and withhold with respect to the making of such payment under applicable tax laws, and any such withheld amounts that are paid to the appropriate governmental authority will be treated for all purposes of the merger agreement as having been paid to the holder of Skagit common stock or equity awards from whom such amounts were deducted or withheld.

Treatment of Skagit Stock Options

        At the effective time of the merger, each Skagit option that is outstanding as of immediately prior to the effective time of the merger will fully vest and be canceled and converted into the right to receive a cash payment, without interest and less applicable withholding taxes, equal to the product of (i) the number of shares of Skagit common stock subject to the Skagit option as of immediately prior to the effective time of the merger and (ii) the excess, if any, of (1) the product of the exchange ratio and the Banner average closing price over (2) the exercise price per share of Skagit common stock subject to such Skagit option as of the effective time of the merger.

Dissenters' Rights

        All shares of Skagit common stock that are issued and outstanding immediately prior to the effective time of the merger and that are held by a Skagit shareholder who did not vote in favor of the merger agreement or the merger and who exercises dissenters' rights when and in the manner required under Chapter 23B.13 of the Washington Business Corporation Act, which we refer to as the "WBCA," will not be converted into or be exchangeable for the right to receive the merger consideration, but instead such holder will be entitled to only such rights as are granted with respect to the payment of the fair value of such shares under the applicable provisions of Chapter 23B.13 of the WBCA. At the effective time of the merger, such dissenting shares will no longer be outstanding and will automatically be canceled and will cease to exist, and such holder will cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the WBCA and the merger agreement, unless and until such holder has failed to perfect or has effectively withdrawn or lost rights to demand or receive the fair value of such shares of Skagit common stock under the WBCA.

        If any shareholder dissenting pursuant to the WBCA and the merger agreement has failed to perfect or has effectively withdrawn or lost any such right, such holder's shares of Skagit common stock will then be treated as if they had been converted into and become exchangeable for the right to receive, as of the effective time of the merger, the merger consideration for each such share of Skagit common stock, in accordance with the merger agreement, without any interest.

        Skagit will give Banner (i) prompt notice of any written notices Skagit receives from or on behalf of its shareholders to exercise dissenters' rights in respect of any shares of Skagit common stock, attempted withdrawals of such notices and any other instruments served pursuant to the WBCA and received by Skagit relating to shareholders' dissenters' rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the WBCA. Skagit may not, except with the prior written consent of Banner, make any payment with respect to, or settle, or offer or agree to settle, any such demand. Any merger consideration made available to the exchange agent to exchange for shares of Skagit common stock for which dissenters' rights have been perfected will be returned to Banner upon demand.

Regulatory Matters

        Banner and Skagit have agreed to cooperate with each other and use their reasonable best efforts to promptly (and in the case of the applications, notices, petitions and filings in respect of the requisite

88

---

Table of Contents

regulatory approvals, within thirty (30) business days of July 25, 2018) prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and governmental entities which are necessary or advisable to consummate the transactions contemplated by the merger agreement, and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such governmental entities.

        Each of Skagit and Banner will, and will cause its subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its subsidiaries with respect to the merger and the bank merger and, subject to the conditions set forth in the merger agreement, to consummate the transactions contemplated by the merger agreement, and (b) to obtain (and to cooperate with the other party to obtain) any consent, authorization, order or approval of, or any exemption by, any governmental entity and any other third party that is advisable or required to be obtained by Skagit or Banner or any of their respective subsidiaries in connection with the merger, the bank merger and the other transactions contemplated by the merger agreement, and each of Banner and Skagit agrees to use its reasonable best efforts to resolve any objections that may be asserted by any governmental entity with respect to the merger agreement or the transactions contemplated by the merger agreement.

        However, under no circumstances will Banner or any of its subsidiaries be required, and Skagit and its subsidiaries will not be permitted (without Banner's written consent), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of governmental entities that would reasonably be expected to be materially burdensome on, or impair in any material respect the benefits of the transactions contemplated by the merger agreement to, Banner, the surviving corporation or their subsidiaries, or have a material and adverse effect on Banner, the surviving corporation and their respective subsidiaries, taken as a whole, or Skagit and its subsidiaries, taken as a whole (in each case, measured on a scale relative to Skagit and its subsidiaries, taken as a whole), after giving effect to the merger (we refer to any of the foregoing as a "materially burdensome regulatory condition").

Skagit Shareholder Meeting; Withdrawal of Recommendation; Restructuring

        Pursuant to the merger agreement, Skagit agreed to call a meeting of its shareholders, to be held as soon as reasonably practicable after the registration statement of which this proxy statement/prospectus forms a part is declared effective, for the purpose of obtaining the vote of Skagit shareholders required to approve the merger agreement, which we refer to as the "requisite Skagit shareholder vote." Skagit and its board must use their reasonable best efforts to obtain from Skagit shareholders such requisite Skagit shareholder vote, including by communicating to Skagit shareholders the Skagit board's recommendation (and including such recommendation in this proxy statement/prospectus) that the Skagit shareholders adopt and approve the merger agreement and the transactions contemplated by the merger agreement, and may not (i) withhold, withdraw, modify or qualify such recommendation in a manner adverse to Banner, (ii) fail to make the Skagit board recommendation in favor of the merger agreement in this proxy statement/prospectus, (iii) adopt, approve, recommend or endorse an acquisition proposal (as defined below) or publicly announce an intention to adopt, approve, recommend or endorse an acquisition proposal, (iv) fail to publicly, finally and without qualification (A) recommend against any acquisition proposal or (B) reaffirm the Skagit board recommendation, in each case within ten (10) business days after such acquisition proposal is made public or any request by Banner to do so (which request may be made once per acquisition proposal, and any material change thereto) (or such fewer number of days as remains prior to the Skagit shareholder meeting), or (v) publicly propose to do any of the foregoing (we refer to any of the foregoing as a "recommendation change").

89

---

Table of Contents

        However, prior to the time the requisite Skagit shareholder vote is obtained, the Skagit board may make a recommendation change if and only if (i) Skagit and its subsidiaries and their representatives have complied with certain non-solicitation and related obligations regarding acquisition proposals, (ii) an unsolicited bona fide written acquisition proposal is made to Skagit after July 25, 2018 by a third party, and such acquisition proposal is not withdrawn, (iii) the Skagit board has concluded in good faith (after consultation with its outside legal counsel and financial advisors) that such acquisition proposal constitutes a superior proposal (as defined below), (iv) the Skagit board has concluded in good faith (after consultation with its outside legal counsel) that failure to make a recommendation change would reasonably be expected to be inconsistent with the directors' fiduciary duties under applicable law, (v) prior to effecting the recommendation change, three (3) business days have elapsed since Skagit has given written notice to Banner advising Banner that Skagit intends to take such action and specifying in reasonable detail the reasons for its change, including the terms and conditions of, and the identity of the person making, any such acquisition proposal that is the basis of the recommendation change (and any amendment or change to any material term of such acquisition proposal will require a new notice and the provisions described in this paragraph will apply anew), (vi) during such three (3)-business day period, Skagit has considered, and engaged in good-faith discussions with Banner regarding, any adjustment or modification of the terms of the merger agreement proposed by Banner, and (vii) the Skagit board, following such three (3)-business day period, again reasonably determines in good faith (after consultation with its outside legal counsel and financial advisors, and taking into account any adjustment or modification of the terms of the merger agreement proposed by Banner and delivered to Skagit in writing) that such acquisition proposal nonetheless continues to constitute a superior proposal and that failure to make a recommendation change would reasonably be expected to be inconsistent with the directors' fiduciary duties under applicable law.

        An "acquisition proposal" means, other than the transactions contemplated by the merger agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of fifteen percent (15%) or more of the consolidated assets of Skagit and its subsidiaries or fifteen percent (15%) or more of any class of equity or voting securities of Skagit or its subsidiaries whose assets, individually or in the aggregate, constitute fifteen percent (15%) or more of the consolidated assets of Skagit, (ii) any tender offer (including a self-tender offer), exchange offer or other acquisition of equity or voting securities that, if consummated, would result in such third party beneficially owning fifteen percent (15%) or more of any class of equity or voting securities of Skagit or its subsidiaries whose assets, individually or in the aggregate, constitute fifteen percent (15%) or more of the consolidated assets of Skagit or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Skagit or its subsidiaries.

        A "superior proposal" means an unsolicited, bona fide written acquisition proposal made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination or acquisition transaction, all or substantially all of the consolidated assets of Skagit and its subsidiaries or all of the outstanding shares of Skagit common stock, and which the Skagit board has in good faith determined (after consultation with its outside legal counsel and financial advisors, and taking into account the terms and conditions of such acquisition proposal and the merger agreement (as it may be proposed to be amended by Banner) and all legal, financial, timing, regulatory and other aspects of such acquisition proposal and the person making the proposal), to be more favorable, from a financial point of view, to Skagit shareholders than the merger with Banner and the transactions contemplated by the merger agreement (as it may be proposed to be amended by Banner) and to be reasonably likely to be consummated on a timely basis on the terms proposed.

        Unless the merger agreement has been terminated in accordance with its terms, the Skagit shareholder meeting must be convened and the merger agreement must be submitted to Skagit

90

Table of Contents

shareholders at the Skagit shareholder meeting for the purpose of voting on the approval of the merger agreement, and Skagit may not submit to the vote of its shareholders any acquisition proposal or any transactions contemplated by such acquisition proposal.

        If Skagit fails to obtain the requisite Skagit shareholder vote at a duly convened Skagit shareholder meeting held for that purpose or any adjournment or postponement thereof, unless the merger agreement has been validly terminated in accordance with its terms, both parties will in good faith use their reasonable best efforts to negotiate a restructuring of the transaction provided for in the merger agreement and/or resubmit the merger agreement and the transactions contemplated by the merger agreement (or as restructured pursuant to this paragraph) to Skagit shareholders for approval. However, neither party will have any obligation to (i) alter or change any material terms, including the amount or kind of the merger consideration, in a manner adverse to such party or its shareholders or (ii) agree to any change that would adversely affect the tax treatment of the merger with respect to such party or its shareholders.

        See also "—Termination of the Merger Agreement" and "—Termination Fee" beginning on pages 95 and 97, respectively, of this proxy statement/prospectus.

No Solicitation

        Skagit has agreed that it will not, and will cause its subsidiaries and its and their officers, directors, employees, agents, advisors, financing sources, investment bankers, attorneys and other representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, any acquisition proposal, (ii) engage or participate in any negotiations with any person concerning any acquisition proposal, (iii) disclose or provide any confidential or nonpublic information to, have or participate in any discussions with, or otherwise cooperate in any way with, any person in connection with or relating to any acquisition proposal (including by affording access to the personnel, properties, books, records or assets of Skagit or its subsidiaries) or (iv) unless the merger agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement entered into in accordance with the merger agreement) in connection with or relating to any acquisition proposal.

        Notwithstanding the restrictions described above, prior to the receipt of the requisite Skagit shareholder vote, in the event Skagit receives an unsolicited bona fide written acquisition proposal after July 25, 2018 that did not result from a breach of the non-solicitation and related provisions of the merger agreement, it may, and may permit its subsidiaries and Skagit's and its subsidiaries' representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the acquisition proposal if and only if the Skagit board determines in good faith (after consultation with its outside legal counsel and financial advisors) that such acquisition proposal constitutes or is reasonably likely to result in a superior proposal and that the failure to take such actions would reasonably be expected to be inconsistent with the directors' fiduciary duties under applicable law. However, prior to providing any such confidential or nonpublic information or participating in such negotiations or discussions, Skagit must give Banner at least five (5) business days' prior written notice and enter into a confidentiality agreement with such third party on terms no less favorable to it than the confidentiality agreement between Banner and Skagit, which confidentiality agreement may not provide such person with any exclusive right to negotiate with Skagit. Skagit will also provide Banner with a copy of any such confidential or nonpublic information provided to any person prior to or simultaneously with furnishing such information to such person, to the extent not previously provided. The merger agreement required Skagit to, and to cause its representatives to, immediately cease any activities, discussions or

91

---

Table of Contents

negotiations conducted before July 25, 2018 with any person other than Banner with respect to any acquisition proposal and to request the return or destruction of any information provided to any such person.

        Skagit will promptly (and within twenty-four (24) hours) advise Banner following receipt of any acquisition proposal or any inquiry which could reasonably be expected to lead to an acquisition proposal, and its substance (including the terms and conditions of and the identity of the person making such inquiry or acquisition proposal) and will provide Banner an unredacted copy of such acquisition proposal and any draft agreements, proposals or other materials or correspondence received in connection with such inquiry or acquisition proposal, and will keep Banner apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or acquisition proposal (including providing an unredacted copy of such amended or revised acquisition proposal and any further or revised draft agreements, proposals or other materials or correspondence received in connection with such inquiry or acquisition proposal). In addition, Skagit will enforce any existing confidentiality agreements to which it or any of its subsidiaries is a party in accordance with the terms thereof and will not release any third party from, or waive any provisions of, any such agreements.

Governance Matters

        The directors of Banner at the effective time of the merger will continue to be the directors of the surviving corporation from and after the effective time of the merger, until their successors are duly elected or appointed. In addition, effective immediately following the effective time of the merger, Banner will take such action as is necessary to appoint Cheryl R. Bishop to the board of directors of the surviving corporation.

        The officers of Banner at the effective time of the merger will continue to be the officers of the surviving corporation from and after the effective time of the merger until their successors are duly elected or appointed, together with such additional persons as may thereafter be elected or appointed.

Expenses

        Except as otherwise expressly provided in the merger agreement, all costs and expenses incurred in connection with the merger agreement and the transactions contemplated by the merger agreement will be paid by the party incurring such expense.

Employee Matters

        During the period commencing at the effective time of the merger and ending on the first anniversary of the effective time of the merger, Banner will provide, or cause to be provided, to each continuing employee of Skagit and its subsidiaries, who continues to be employed by Banner and its subsidiaries after the effective time of the merger, (i) a base salary or wage rate that is no less favorable than the base salary or wage rate provided by Skagit or any such subsidiary, as applicable, to such continuing employee immediately prior to the effective time of the merger, (ii) an annual cash incentive compensation opportunity that is no less favorable than that provided to similarly situated employees of Banner and its subsidiaries, and (iii) employee benefits that are substantially comparable in the aggregate to the employee benefits provided to similarly situated employees of Banner and its subsidiaries (which requirement Banner may satisfy by providing employee benefits that are substantially comparable in the aggregate to the employee benefits provided by Skagit or its subsidiaries to such continuing employees immediately prior to the effective time of the merger until such time as such continuing employees commence participation in the applicable employee benefit plans of Banner and its subsidiaries).

Table of Contents

        In addition, Banner will, or will cause one of its subsidiaries to, provide to each continuing employee whose employment terminates during the 12-month period following the closing date and who is not party to an individual change-in-control or severance agreement with severance benefits equal to the severance benefits for which such continuing employee would be eligible under the severance plans or policies of Banner or its affiliates.

        Following the effective time of the merger, Banner will cause any Banner benefit plans in which Skagit employees are eligible to participate to recognize and provide credit for the service of each continuing employee with Skagit and its subsidiaries (and any predecessor thereto) prior to the effective time of the merger for purposes of eligibility, vesting and level of benefits under such Banner plans, subject to certain exceptions. With respect to any Banner plan that provides medical, dental or vision insurance benefits, for the plan year in which such continuing employee is first eligible to participate, Banner will use commercially reasonable efforts to (1) cause any preexisting condition limitations or eligibility waiting periods under such plan to be waived with respect to such continuing employee to the extent such limitation would have been waived or satisfied under the Skagit benefit plan in which such continuing employee participated immediately prior to the effective time of the merger, and (2) credit each continuing employee for any co-payments, deductibles or out-of-pocket expenses incurred by such continuing employee and his or her eligible dependents in such plan year for purposes of any applicable co-payment, deductible and annual out-of-pocket expense requirements under any such Banner plan.

Indemnification and Insurance

        The merger agreement provides that, for a period of six (6) years from and after the effective time of the merger, to the fullest extent permitted by applicable law, the surviving corporation will indemnify and hold harmless, to the extent such persons are indemnified as of July 25, 2018 by Skagit pursuant to Skagit's articles of incorporation and bylaws, or pursuant to certain indemnification agreements in effect on July 25, 2018, and will also advance expenses as incurred to the extent provided under Skagit's articles of incorporation and bylaws (or such indemnification agreements), each present and former director and officer of Skagit and its subsidiaries (in each case, when acting in such capacity) against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the effective time of the merger, arising out of the fact that such person is or was a director or officer of Skagit or any of its subsidiaries and pertaining to matters existing or occurring at or prior to the effective time of the merger, including the transactions contemplated by the merger agreement, subject to such person providing an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

        The merger agreement requires that, for a period of six (6) years after the effective time of the merger, the surviving corporation maintain Skagit's existing directors' and officers' liability insurance policies, or policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured, with respect to claims arising from facts or events which occurred at or before the effective time of the merger. However, the surviving corporation is not required to expend, on an annual basis, an amount in excess of 250% of the current annual premium paid as of July 25, 2018 by Skagit for such insurance, and if such premiums for such insurance would at any time exceed that amount, then the surviving corporation will maintain policies of insurance which, in the surviving corporation's good faith determination, provide the maximum coverage available at an annual premium not exceeding the premium cap. In lieu of the foregoing, Banner or Skagit, in consultation with, but only upon the consent of Banner (which consent may not be unreasonably withheld, conditioned or delayed), may (and at the request of Banner, Skagit will) obtain at or prior to the effective time of the merger a six-year "tail" policy under Skagit's existing

93

Table of Contents

directors' and officers' liability insurance policy providing equivalent coverage to that described above, if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the premium cap.

Special Dividend

        After adjusted shareholders' equity has been finally determined pursuant to the merger agreement for purposes of determining any adjustment to the exchange ratio and the merger consideration, to the extent adjusted shareholders' equity exceeds $80 million, the Skagit board may, upon written notice to Banner and effective immediately prior to the closing, declare and pay a special dividend to Skagit shareholders in an amount not to exceed such excess.

Certain Additional Covenants

        The merger agreement also contains additional covenants, including, among others, covenants relating to the filing of this proxy statement/prospectus, the listing of shares of Banner common stock to be issued in the merger, access to information and confidentiality, coordination with respect to litigation relating to the merger, conversion and integration matters, and public announcements with respect to the transactions contemplated by the merger agreement.

•

by mutual written consent of Banner and Skagit;

95

Table of Contents

date is due to the failure of the party seeking to terminate the merger agreement to perform or comply with its obligations, covenants and agreements under the merger agreement;

•

by either Banner or Skagit (provided that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained in the merger agreement), if there is a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the merger agreement on the part of the other party, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the closing date, the failure of an applicable closing condition of the terminating party, and which is not cured within thirty (30) days following written notice to the party committing such breach, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the termination date);



•

by Skagit, if (i) Skagit has complied in all material respects with its non-solicitation and related obligations and certain provisions of the merger agreement related to shareholder approval and the Skagit board recommendation, (ii) the Skagit shareholder meeting (including any postponements or adjournments thereof) has concluded with the vote to approve the merger agreement having been taken and the requisite Skagit shareholder vote has not been obtained and (iii) prior to the Skagit shareholder meeting, Skagit received a superior proposal which did not result from a breach of certain provisions of the merger agreement related to Skagit's non-solicitation and related obligations or its obligations related to shareholder approval and the Skagit board recommendation and the Skagit board has determined to enter into a definitive agreement providing for such superior proposal upon termination of the merger agreement in accordance with the termination provision of the merger agreement and has entered into such agreement concurrently with such termination; provided, that following such Skagit shareholder meeting (including any postponements or adjournments thereof) and prior to such termination, Skagit has complied with certain notice and good faith negotiation obligations during a three (3)-business day period equivalent to those applicable in connection with a recommendation change, as described under "—Skagit Shareholder Meeting; Withdrawal of Recommendation; Restructuring";



•

by Banner, if the Skagit shareholder meeting (including any postponements or adjournments thereof) has concluded with the vote to approve the merger agreement having been taken and the requisite Skagit shareholder vote has not been obtained; or

Termination Fee

        Skagit will be required to pay Banner a termination fee of $7.75 million if the merger agreement is terminated in one of the following circumstances:

•

In the event that, after July 25, 2018 and prior to the termination of the merger agreement, (i) a bona fide acquisition proposal has been communicated to or otherwise made known to the Skagit board or senior management or has been made directly to Skagit shareholders, or any person has publicly announced an acquisition proposal with respect to Skagit, (ii) thereafter the merger agreement is terminated (A) by either Banner or Skagit because the merger has not been completed prior to the termination date, and Skagit has not obtained the requisite Skagit shareholder vote but all other conditions to Skagit's obligation to complete the merger had been satisfied or were capable of being satisfied prior to such termination, (B) by Banner based on a breach of the merger agreement by Skagit that would constitute the failure of an applicable closing condition, or (C) by Banner based on the requisite Skagit shareholder vote not being obtained at the conclusion of the Skagit shareholder meeting (including any postponements or adjournments thereof), and (iii) prior to the date that is twelve (12) months after the date of such termination, Skagit enters into a definitive agreement or consummates a transaction with respect to an acquisition proposal (whether or not the same acquisition proposal as that referred to above), provided that for purposes of the foregoing, all references in the definition of acquisition proposal to "15%" will instead refer to "50%." In such case, the termination fee must be paid to Banner on the earlier of the date Skagit enters into such definitive agreement and the date of consummation of such transaction.



•

In the event that the merger agreement is terminated by Banner pursuant to the last bullet set forth under "The Merger Agreement—Termination of the Merger Agreement" above. In such case, the termination fee must be paid to Banner within two (2) business days of the date of termination.



•

In the event that the merger agreement is terminated by Skagit pursuant to the third from the last bullet set forth under "The Merger Agreement—Termination of the Merger Agreement" above. In such case, the termination fee must be paid to Banner concurrently with, and as a condition to the effectiveness of, such termination.

Amendment and Modification

        The merger agreement may be amended by the parties, at any time before or after receipt of the requisite Skagit shareholder vote. However, after the receipt of the requisite Skagit shareholder vote, there may not be, without further approval of such shareholders, any amendment of the merger agreement that requires such further approval under applicable law. The merger agreement may not be amended except by an instrument in writing signed on behalf of each of the parties thereto.

        At any time prior to the effective time of the merger, the parties may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any inaccuracies in the representations and warranties of the other party contained in the merger agreement or in any document delivered by such other party pursuant to the merger agreement and (c) waive compliance with any of the agreements or satisfaction of any conditions for its benefit contained in the merger agreement. Any agreement on the part of a party to any extension or waiver must be in writing signed on behalf of that party.

Governing Law; Jurisdiction

        The merger agreement is governed by and will be construed in accordance with the laws of the State of Washington, without regard to any applicable conflicts of law. The parties agree that any action

97

---

Table of Contents

or proceeding in respect of any claim arising out of or related to the merger agreement or the transactions contemplated thereby will be brought exclusively in any federal or state court of competent jurisdiction located in the State of Washington.

Specific Performance

        Each party will be entitled to an injunction or injunctions to prevent breaches or threatened breaches of the merger agreement or to enforce specifically the performance of the terms and provisions of the merger agreement, in addition to any other remedy to which they are entitled at law or in equity.

Voting and Support Agreements

        In connection with the execution of the merger agreement, Banner entered into voting and support agreements with the directors and executive officers of Skagit and/or their affiliates, in which each such person agreed, among other things, to vote the shares of Skagit common stock owned beneficially or of record by such person and over which it has voting power in favor of the merger agreement and the proposal to adjourn or postpone the special meeting of the Skagit shareholders to a later date if there are not sufficient votes to approve the merger agreement, and against any alternative acquisition proposal or other action that would prevent, impede, interfere with, delay, postpone, discourage or frustrate the purposes of or adversely affect the consummation of the transactions contemplated by the merger agreement, as well as certain other restrictions with respect to the voting and transfer of such person's shares of Skagit common stock.

        The voting and support agreements also contain certain confidentiality, non-solicitation and, in the case of the voting and support agreements executed by independent directors of Skagit, non-competition covenants, which are applicable upon the closing of the merger and remain in effect for a period of two (2) years after the closing date. If the merger agreement is terminated, the Skagit voting and support agreements will also terminate and be null and void and of no effect, except certain provisions will survive any such termination and such termination will not relieve any party of any liability or damages resulting from any willful or material breach of any of its representations, warranties, covenants or other agreements therein.

        The preceding discussion is a summary of the Skagit voting and support agreements and is qualified in its entirety by reference to the form of the Skagit voting and support agreement, which is provided in its entirety as Annex D to this proxy statement/prospectus.

ADJOURNMENT OF THE SPECIAL MEETING TO SOLICIT
ADDITIONAL PROXIES

        Skagit shareholders are being asked to approve one or more adjournments of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement. If this proposal is approved, the special meeting could be successively adjourned to any date. Skagit does not intend to adjourn the special meeting to solicit additional proxies if the merger agreement is approved at the special meeting.

        The Skagit board unanimously recommends that you vote "FOR" the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

        The following discussion describes the material U.S. federal income tax consequences of the merger to "U.S. holders" (as defined below) of Skagit common stock that exchange their Skagit common stock for Banner common stock in the merger. The following discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder and judicial and administrative authorities, rulings and decisions, all as in effect as of the date of this proxy statement/prospectus. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010, nor does it address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax.

        The following discussion applies only to U.S. holders who hold their shares of Skagit common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). Further, this discussion does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws (such as, for example, dealers or brokers in securities, commodities or foreign currencies, traders in securities that elect to apply a mark-to-market method of accounting, banks and certain other financial institutions, insurance companies, mutual funds, tax-exempt organizations, holders subject to the alternative minimum tax provisions of the Code, partnerships, S corporations or other pass-through entities or investors therein, regulated investment companies, real estate investment trusts, former citizens or residents of the United States, U.S. expatriates, holders whose functional currency is not the U.S. dollar, holders who hold Skagit common stock as part of a hedge, straddle, constructive sale or conversion transaction or other integrated investment, retirement plans, individual retirement accounts, or other tax-deferred accounts or holders who acquired Skagit common stock pursuant to the exercise of employee stock options, through a tax qualified retirement plan or otherwise as compensation).

        For purposes of this discussion, the term "U.S. holder" means a beneficial owner of Skagit common stock that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation, or entity treated as a corporation for U.S. federal income tax purposes, organized under the laws of the United States or any state thereof or the District of Columbia, (3) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes or (4) an estate, the income of which is subject to U.S. federal income tax, regardless of its source.

        If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Skagit common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Any entity treated as a partnership for U.S. federal income tax purposes that holds Skagit common stock, and any partners in such partnership, should consult their own tax advisors regarding the U.S. federal, state, local, foreign or other tax consequences of the merger to them in light of their particular circumstances.

        All holders should consult their own tax advisors regarding the specific tax consequences of the merger to them in light of their particular facts and circumstances, including with respect to the applicability and effect of any U.S. federal, state, local, foreign or other tax laws.

        It is a condition to the obligation of Banner to complete the merger that Banner receives an opinion from Wachtell, Lipton, Rosen & Katz, dated as of the closing date of the merger, to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code. It

is a condition to the obligation of Skagit to complete the merger that Skagit receives an opinion from Miller Nash Graham & Dunn LLP, dated as of the closing date of the merger, to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code. These opinions will be based on facts and representations contained in representation letters provided by Banner and Skagit and on customary factual assumptions. Neither of the opinions described above will be binding on the Internal Revenue Service (which we refer to as the "IRS"), or any court. Banner and Skagit have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which these opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected.

U.S. Federal Income Tax Consequences to U.S. Holders

        Assuming the receipt and accuracy of the opinions described above, you generally will not recognize gain or loss on the exchange of Skagit common stock for Banner common stock in the merger, except with respect to cash received instead of fractional shares of Banner common stock (as discussed below). The aggregate tax basis of the Banner common stock that you receive in the merger (including any fractional shares deemed received and redeemed for cash as described below) will equal your aggregate adjusted tax basis in the Skagit common stock you surrender in the merger. Your holding period for the Banner common stock that you receive in the merger (including any fractional share deemed received and redeemed for cash as described below) will include your holding period of the Skagit common stock that you surrender in the merger.

        If you acquired different blocks of Skagit common stock at different times or at different prices, the Banner common stock you receive will be allocated pro rata to each block of Skagit common stock, you should consult your tax advisors as to the determination of the tax bases and holding periods of the shares of Banner common stock received in the merger.

Cash Instead of Fractional Shares

        If you receive cash instead of a fractional share of Banner common stock in the merger, you will be treated as having received such fractional share of Banner common stock pursuant to the merger and then as having sold such fractional share of Banner common stock for cash. As a result, you generally will recognize gain or loss equal to the difference between the amount of cash received and the basis in your fractional share of Banner common stock as set forth above. Such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such fractional share (including the holding period of Skagit common stock surrendered therefor) exceeds one year. Long-term capital gains of individuals are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

        Payments of cash to a U.S. holder may be subject, under certain circumstances, to information reporting and backup withholding (currently at a rate of 24%). You generally will not be subject to backup withholding, however, if you (1) furnish a correct taxpayer identification number, certify that you are not subject to backup withholding and otherwise comply with all the applicable requirements of the backup withholding rules; or (2) provide proof that you are otherwise exempt from backup withholding. Any amounts withheld under the backup withholding rules are not an additional tax and will generally be allowed as a refund or credit against your U.S. federal income tax liability, provided you timely furnish the required information to the IRS.

Table of Contents

        This discussion of certain material U.S. federal income tax consequences is not intended to be, and should not be construed as, tax advice. Skagit shareholders are urged to consult their independent tax advisors with respect to the application of U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the U.S. federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

DESCRIPTION OF BANNER'S CAPITAL STOCK

        The following briefly summarizes the material terms of Banner's capital stock. The summary does not purport to be exhaustive and is qualified in its entirety by reference to Banner's articles of incorporation, bylaws and applicable Washington law.

General

        The authorized capital stock of Banner consists of 55,500,000 shares of capital stock, presently classified as follows:

•

50,000,000 shares of common stock, par value $0.01 per share;



•

5,000,000 shares of nonvoting common stock, par value $0.01 per share; and



•

500,000 shares of serial preferred stock, par value $0.01 per share.

        As of September 4, 2018, there were 32,327,824 shares of Banner common stock, 74,933 shares of Banner nonvoting common stock and no shares of Banner preferred stock issued and outstanding. Banner's common stock is traded on the NASDAQ under the symbol "BANR."

Common Stock

        Each share of Banner common stock has the same relative rights and is identical in all respects with each other share of Banner common stock.

        Subject to any prior rights of the holders of any preferred stock of Banner then outstanding, holders of Banner common stock are entitled to receive such dividends as are declared by Banner's board of directors out of funds legally available for dividends.

        Except with respect to greater than 10% shareholders, full voting rights are vested in the holders of Banner common stock and each share is entitled to one vote. See the sections entitled "Comparison of Shareholders' Rights—Voting Rights" and "Comparison of Shareholders' Rights—Voting Limitations." Subject to any prior rights of the holders of any Banner preferred stock then outstanding, in the event of a liquidation, dissolution or winding up of Banner, holders of shares of Banner common stock (and the holders of any class or series of stock entitled to participate with the common stock in the distribution of assets) are entitled to receive, pro rata, any assets distributable to shareholders in respect of shares held by them. Holders of shares of Banner common stock do not have any preemptive rights to subscribe for any additional securities which may be issued by Banner, nor do they have cumulative voting rights.

Nonvoting Common Stock

        The holders of Banner nonvoting common stock have no voting rights except as required by the WBCA and as described in the next sentence. In addition to any other vote required by law, the affirmative vote of the holders of a majority of the outstanding shares of Banner nonvoting common stock, voting separately as a class, is required to amend Banner's articles of incorporation to alter or change the designation, preferences, limitations or relative rights of all or part of the shares of Banner nonvoting common stock.

        Except with respect to voting, Banner nonvoting common stock and Banner common stock have the same rights, preferences and privileges, share ratably in all assets of the corporation upon its liquidation, dissolution or winding-up, are entitled to receive dividends (other than certain stock dividends described in the next sentence) in the same amount per share and at the same time, as and if declared by Banner's board of directors, and are equal and identical in all other respects as to all other matters. In the event of any stock dividend having the effect of a stock split, stock combination or

103

---

Table of Contents

other reclassification of shares of either the Banner common stock or the Banner nonvoting common stock, the outstanding shares of the other class will be proportionately split, combined or reclassified in a similar manner, except that holders of Banner common stock will receive only shares of Banner common stock in respect of their shares of Banner common stock and holders of Banner nonvoting common stock will receive only shares of Banner nonvoting common stock in respect of their shares of Banner nonvoting common stock.

        No transfer of shares of Banner nonvoting common stock by the initial holders of those shares (or such holders' affiliates) is permitted, except for specified permitted transfers or transfers to affiliates of the initial holders of the nonvoting common stock. Each share of nonvoting common stock will be converted automatically into one share of common stock upon a permitted transfer.

        In the event of any merger, consolidation, reclassification or other transaction in which the shares of Banner common stock are exchanged for or changed into other stock or securities, cash and/or any other property, each share of Banner nonvoting common stock will simultaneously be similarly exchanged or changed into an amount per whole share equal to the aggregate amount of stock, securities, cash and/or any other property that such Banner nonvoting common stock would be entitled to receive if it were converted into a share of Banner common stock immediately prior to such transaction. In case of any offer to repurchase shares, pro rata subscription offer, rights offer or similar offer to holders of Banner common stock, Banner is required to provide the holders of Banner nonvoting common stock the right to participate.

Preferred Stock

        Banner's articles of incorporation permit Banner's board of directors to authorize the issuance of up to 500,000 shares of preferred stock, par value $0.01, in one or more series, at such time or times and for such consideration as Banner's board of directors may determine, without shareholder action. Banner's board of directors is expressly authorized at any time, and from time to time, to issue Banner preferred stock, and to fix such voting powers, designations, preferences and relative, participating, optional or other special rights of the shares of each such series and the qualifications, limitations and restrictions thereof, including, but not limited to fixing the series and the number of shares comprising such series, the dividend rate on the shares of such series, the redemption rights, if any, any purchase, retirement or sinking fund provisions, any conversion rights and any voting rights. The ability of Banner's board of directors to approve the issuance of preferred or other stock without shareholder approval could dilute the voting power or other rights or adversely affect the market value of Banner common stock and may make an acquisition by an unwanted suitor of a controlling interest in Banner more difficult, time-consuming or costly, or otherwise discourage an attempt to acquire control of Banner.

        Each share of each series of preferred stock will have the same relative rights as and is identical in all respects with all other shares of the same series.

Anti-Takeover Provisions

        In addition to the ability to issue preferred stock without shareholder approval, Banner's articles of incorporation and bylaws contain a number of other provisions which may have the effect of delaying, deferring or preventing a change in control of Banner. See the section entitled "Comparison of Shareholders' Rights."

COMPARISON OF SHAREHOLDERS' RIGHTS

        Both Banner and Skagit are incorporated under the laws of the State of Washington, and, accordingly, the rights of the shareholders of Banner and Skagit are governed by Washington law. The rights of shareholders of Skagit under the articles of incorporation and bylaws of Skagit differ in some respects from the rights that shareholders of Skagit will have as shareholders of Banner under the articles of incorporation and bylaws of Banner following the merger.

        Certain material differences between the provisions contained in the articles of incorporation and bylaws of Banner and the articles of incorporation and bylaws of Skagit, as such differences may affect the rights of shareholders, are summarized below. The summary set forth below is as of the date of this proxy statement/prospectus and is not intended to be a complete statement of the rights of shareholders of the two companies or a complete description of the specific provisions referred to below. This summary is qualified by reference to Washington law, as appropriate, and the articles of incorporation and bylaws of Banner and the articles of incorporation and bylaws of Skagit. Copies of Banner's articles of incorporation and bylaws have been previously filed by Banner with the SEC. To find out where copies of these documents and the articles of incorporation and bylaws of Skagit can be obtained, see the section entitled "Where You Can Find More Information" beginning on page 120 of this proxy statement/prospectus.

              AGREEMENT AND PLAN OF MERGER, dated as of July 25, 2018 (this "Agreement"), by and between Skagit Bancorp, Inc., a Washington corporation (the "Company"), and Banner Corporation, a Washington corporation ("Parent").

W I T N E S S E T H:

              WHEREAS, the Boards of Directors of Parent and the Company have determined that it is in the best interests of their respective companies and their shareholders to consummate the strategic business combination transaction provided for herein, pursuant to which the Company will, subject to the terms and conditions set forth herein, merge with and into Parent (the "Merger"), so that Parent is the surviving corporation (hereinafter sometimes referred to in such capacity as the "Surviving Corporation") in the Merger;

              WHEREAS, the Boards of Directors of Parent and the Company have adopted and approved this Agreement and the transactions contemplated hereby, including the Merger, and the Board of Directors of the Company has resolved to recommend that the shareholders of the Company approve and adopt this Agreement and the transactions contemplated hereby, including the Merger;

Parent. Parent shall be the Surviving Corporation in the Merger, and shall continue its corporate existence under the laws of the State of Washington. Upon consummation of the Merger, the separate corporate existence of the Company shall terminate.

                             1.2        Closing.   Subject to the terms and conditions of this Agreement, the closing of the Merger (the "Closing") will take place at 10:00 a.m. Seattle time, at the offices of Wachtell, Lipton, Rosen & Katz, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date."

                             1.3        Effective Time.   Subject to the terms and conditions of this Agreement, at the Closing, the parties shall execute, and Parent and the Company shall cause to be filed articles of merger with the Secretary of State of the State of Washington (the "Washington Secretary") and a plan of merger, as provided in the relevant provisions of the WBCA (collectively, the "Articles of Merger"). The Merger shall become effective at such time as designated in the Articles of Merger, or if no time is designated, at the time of filing of the Articles of Merger. The term "Effective Time" shall be the date and time when the Merger becomes effective, as set forth in the Articles of Merger (or if no time is designated, at the time of filing of the Articles of Merger).

                             1.4        Effects of the Merger.   At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the WBCA.

                             1.5        Conversion of Company Common Stock.   At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Company or the holder of any of the following securities:

                             (a)          Subject to Section 2.2(e), each share of the common stock, no par value, of the Company issued and outstanding immediately prior to the Effective Time (the "Company Common Stock"), except for the Cancelled Shares and Dissenting Shares, shall be converted into the right to receive, without interest, 5.6664 shares, subject to adjustment pursuant to Section 1.13 (as adjusted pursuant to Section 1.13, the "Exchange Ratio"), of the common stock, par value $0.01 per share, of Parent (the "Parent Common Stock") (the "Merger Consideration"); it being understood that upon the Effective Time, pursuant to Section 1.6, the Parent Common Stock, including the shares issued to former holders of Company Common Stock, shall be the common stock of the Surviving Corporation.

                             (b)         All of the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an "Old Certificate," it being understood that any reference herein to "Old Certificate" shall be deemed to include reference to book-entry account statements relating to the ownership of shares of Company Common Stock) previously representing any such shares of Company Common Stock shall thereafter represent only the right to receive (i) the Merger

Table of Contents

Consideration, including without duplication, cash in lieu of fractional shares which the shares of Company Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e) and (ii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b) upon the surrender of such Old Certificates in accordance with Section 2.2, in each case without any interest thereon. If, prior to the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split, an appropriate and proportionate adjustment shall be made to the Exchange Ratio and the Merger Consideration to give holders of Company Common Stock and Parent the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing contained herein shall be construed to permit Parent or the Company to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.

                             (c)           At the Effective Time, all shares of Company Common Stock that are directly owned by the Company or Parent (in each case, other than (i) shares of Company Common Stock held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties or (ii) shares of Company Common Stock held, directly or indirectly, by Parent or the Company in respect of a debt previously contracted) shall be cancelled and shall cease to exist and no Merger Consideration or other consideration shall be delivered in exchange therefor (such cancelled shares, the "Cancelled Shares").

                             (d)          Notwithstanding anything in this Agreement to the contrary, all shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by a holder of Company Common Stock who did not vote in favor of this Agreement or the Merger (or consent thereto in writing) and who exercises dissenters' rights when and in the manner required under Chapter 23B.13 of the WBCA (the "Dissenting Shares"), shall not be converted into or be exchangeable for the right to receive the Merger Consideration, but instead such holder shall be entitled to only such rights as are granted with respect to the payment of the fair value of such shares under the applicable provisions of Chapter 23B.13 of the WBCA (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of Chapter 23B.13 of the WBCA and this Section 1.5(d)), unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost rights to demand or receive the fair value of such shares of Company Common Stock under the WBCA. If any shareholder dissenting pursuant to Chapter 23B.13 of the WBCA and this Section 1.5(d) shall have failed to perfect or shall have effectively withdrawn or lost any such right, such holder's shares of Company Common Stock shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration for each such share of Company Common Stock, in accordance with Section 1.5(a), without any interest thereon. The Company shall give Parent (i) prompt notice of any written notices the Company receives from or on behalf of its shareholders to exercise dissenters' rights in respect of any shares of Company Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to Chapter 23B.13 of the WBCA and received by the Company

Table of Contents

relating to shareholders' dissenters' rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under Chapter 23B.13 of the WBCA. The Company shall not, except with the prior written consent of Parent, make any payment with respect to, or settle, or offer or agree to settle, any such demand. Any Merger Consideration made available to the Exchange Agent to exchange for shares of Company Common Stock for which dissenters' rights have been perfected shall be returned to Parent upon demand.

                             1.6        Parent Common Stock.   At and after the Effective Time, each share of Parent Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Corporation and shall not be affected by the Merger.

                             1.7        Treatment of Company Equity Awards.   

                             (a)         Company Stock Options.  At the Effective Time, each compensatory option to purchase Company Common Stock granted by the Company (a "Company Option") that is outstanding as of immediately prior to the Effective Time shall fully vest (to the extent unvested) and shall be cancelled and converted into the right to receive a cash payment, without interest and less applicable withholding taxes, equal to the product of (i) the number of shares of Company Common Stock subject to the Company Option as of immediately prior to the Effective Time and (ii) the excess, if any, of the Merger Consideration Value over the exercise price per share of Company Common Stock subject to such Company Option as of the Effective Time. If the per share exercise price of a Company Option that is outstanding as of immediately prior to the Effective Time is equal to or greater than the Merger Consideration Value, then such Company Option shall be cancelled at the Effective Time for no consideration. For purposes of this Agreement, "Merger Consideration Value" means the product of (A) the Exchange Ratio and (B) the Parent Share Closing Price.

                             (b)         At or prior to the Effective Time, the Company, the Board of Directors of the Company and its Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the provisions of this Section 1.7, including providing notice to the holders of Company Options in accordance with Section 6(l) of the Amended and Restated 2005 Incentive Stock Plan of the Company (which notice shall be in a form mutually agreed by the Company and Parent).

                             1.8        Articles of Incorporation of the Surviving Corporation.   At the Effective Time, the Amended and Restated Articles of Incorporation of Parent (the "Parent Articles"), as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation of the Surviving Corporation, until thereafter duly amended in accordance with the terms thereof and applicable law.

                             1.9        Bylaws of the Surviving Corporation.   At the Effective Time, the Bylaws of Parent (the "Parent Bylaws"), as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation, until thereafter duly amended in accordance with the terms thereof and applicable law.

                             1.10      Tax Consequences.   It is intended that the Merger shall qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a "plan of reorganization" for the purposes of Sections 354 and 361 of the Code.

                             1.11      Bank Merger.   Immediately following the Merger, Skagit Bank ("Company Bank"), a Washington state-chartered commercial bank and a wholly owned Subsidiary of the Company, will merge (the "Bank Merger") with and into Banner Bank ("Parent Bank"), a Washington state-chartered commercial bank and a wholly owned Subsidiary of Parent. Parent Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of Company Bank shall cease. The parties agree that the Bank Merger shall become effective immediately after the Effective Time. Promptly after the date of this Agreement, Parent and the Company shall cause Parent Bank and Company Bank, respectively, to enter into an agreement and plan of merger in form and substance agreed to by Parent and the Company, which shall be customary for mergers similar to the Bank Merger (the "Bank Merger Agreement"), and Parent, as the sole shareholder of Parent Bank, and the Company, as the sole shareholder of Company Bank, shall each approve and adopt the Bank Merger Agreement. The Company shall cause Company Bank, and Parent shall cause Parent Bank, to execute such articles of merger and such other documents and certificates as are necessary to make the Bank Merger effective ("Bank Merger Articles") immediately following the Effective Time.

                             1.12      Determination of Adjusted Shareholders' Equity.   

                             (a)         For purposes of this Agreement, "Adjusted Shareholders' Equity" means the consolidated stockholders' equity of the Company as set forth in the Final Closing Statement prepared in accordance with, and subject to adjustment as set forth in, Section 1.12, minus any declared but unpaid dividends as of the Shareholders' Equity Measuring Date (or thereafter declared), plus the sum of (i) all fees and expenses of all attorneys, accountants, investment bankers and other advisors and agents for the Company for services rendered in connection with the transactions contemplated by this Agreement, (ii) any employee severance, retention or change-in-control payments or expenses consistent with the terms of this Agreement, (iii) any payment made or expense accrued for the purchase of a directors' and officers' liability insurance policy pursuant to Section 6.7(b), and (iv) other third-party costs, fees and expenses in an aggregate amount not to exceed $50,000, in each case of clauses (i)-(iv) specifically incurred or accrued by the Company in connection with the transactions contemplated hereby (as outlined in the example Interim Closing Statement set forth in Section 1.12(b) of the Company Disclosure Schedules) (collectively, "Transaction Costs"), and in each case, paid by the Company or payable by the Company prior to the Effective Time to the extent reflected as accrued liabilities in the Final Closing Statement.

                             (b)         Not later than five (5) days after each month-end during the period from the date of this Agreement until the Final Closing Statement is delivered to Parent, the Company shall, in consultation with Parent and consistent with past practice, prepare in good faith and deliver to Parent (i) the Company's consolidated financial statements presenting (x) the financial condition of the Company and its Subsidiaries on a consolidated basis as of the close of business on the last day of such month-end and (y) the Company's and its Subsidiaries' consolidated

A-5

Table of Contents

results of operations for the period from January 1, 2018 through the close of business on the last day of such month-end and (ii) a statement setting forth Adjusted Shareholders' Equity as if such month-end were the Shareholders' Equity Measuring Date (each such statement, an "Interim Closing Statement"). Each Interim Closing Statement shall have been prepared in accordance with GAAP and other applicable legal and accounting requirements, and reflect all period-end accruals and other adjustments and shall also reflect accruals for all Transaction Costs or other liabilities incurred or expected to be incurred at any time at or prior to the Closing, including in connection with the transactions contemplated by this Agreement (whether or not doing so is in accordance with GAAP). An example Interim Closing Statement for the month ended June 30, 2018 that satisfies the foregoing requirements (including a proper calculation of Adjusted Shareholders' Equity) is set forth in Section 1.12(b) of the Company Disclosure Schedules. In the event Parent notifies the Company that it disputes any part of any Interim Closing Statement (including Adjusted Shareholders' Equity stated therein), the Company shall cooperate with Parent in good faith to resolve such dispute as promptly as possible.

                             (c)           Not later than five (5) days after the end of the month preceding the month that includes the Anticipated Closing Date, the Company shall, in consultation with Parent, prepare in good faith and deliver to Parent an updated Interim Closing Statement as of and through the close of business on the last day of the month-end immediately preceding the Anticipated Closing Date (such statement as it may be adjusted in accordance with Section 1.12(f), the "Final Closing Statement"); provided, however, that if the Anticipated Closing Date is in the first eight (8) days of a calendar month, then the Final Closing Statement shall be prepared as of the month-end of the second month preceding the Anticipated Closing Date (i.e., if the Anticipated Closing Date is on October 1, then the Final Closing Statement shall be prepared as of and through August 31) (the date which the Final Closing Statement is as of and through, the "Shareholders' Equity Measuring Date"). Such Final Closing Statement shall be prepared in a manner consistent with the Interim Closing Statements, and for the avoidance of doubt, shall set forth Adjusted Shareholders' Equity as of the Shareholders' Equity Measuring Date. The Company shall also deliver to Parent a certificate of the Company's chief financial officer, dated as of the Closing Date, to the effect that the financial statements set forth in the Final Closing Statement continue to reflect accurately, as of the Closing Date, the financial condition of the Company and its Subsidiaries in all material respects and meet the requirements of this Section 1.12(c). For purposes of this Agreement, "Anticipated Closing Date" means the date on which the Closing is expected to occur based on the provisions of Section 1.2, as reasonably agreed in good faith and confirmed in writing by Parent and Company as promptly as practicable.

                             (d)          Parent shall have the right to review, and shall have reasonable access to, all relevant books and records, work papers, schedules, memoranda and other documents prepared by the Company or its Subsidiaries or its and their respective accountants in connection with the Company's preparation of the Interim Closing Statements and the Final Closing Statement, as well as to executive, finance and accounting personnel of the Company and its Subsidiaries and any other information which Parent may reasonably request in connection with its review of the Interim Closing Statements and the Final Closing Statement. The Company will, and will cause its Subsidiaries and its and their accountants and other representatives to, cooperate with and assist Parent and its accountants and other representatives in the review of the Interim Closing Statements and the Final Closing Statement.

                             (e)           In the event Parent disputes the Final Closing Statement (including Adjusted Shareholders' Equity set forth therein), Parent shall, no later than the later of (i) three (3) days after receiving the Final Closing Statement and (ii) two (2) days prior to the Anticipated Closing Date, give the Company written notice of its objections thereto (the "Objection Notice"), describing the nature of the dispute in reasonable detail and specifying those items and amounts as to which Parent disagrees and, based on the information at its disposal, specifying Parent's proposed calculation of Adjusted Shareholders' Equity. If Parent does not timely deliver an Objection Notice prior to the date specified in the previous sentence, Adjusted Shareholders' Equity set forth in the Final Closing Statement delivered by the Company shall be utilized for the calculation of the adjustment to the Exchange Ratio pursuant to Section 1.13 and shall be final and binding on all the parties. Any items or amounts set forth in the Final Closing Statement as to which Parent does not disagree in the Objection Notice shall be final and binding on all the parties.

                             (f)           If Parent timely delivers an Objection Notice, Parent and the Company shall cooperate in good faith to resolve such dispute, and if resolved, the Final Closing Statement and Adjusted Shareholders' Equity as determined by Parent and the Company in writing shall be utilized for calculation of the adjustment to the Exchange Ratio pursuant to Section 1.13 and shall be final and binding on all the parties. If Parent and the Company cannot resolve the dispute within five (5) days after the date of the Objection Notice (the "Negotiation Period"), Parent and the Company shall appoint a mutually acceptable independent accounting firm of national or regional reputation (the "Independent Accounting Firm") to promptly review this Agreement and the disputed items in the Objection Notice and arbitrate the dispute and determine the Final Closing Statement and Adjusted Shareholders' Equity. The Independent Accounting Firm shall be given reasonable access to all records, work papers, schedules, memoranda and other documents relevant to such dispute. The Independent Accounting Firm shall be limited to addressing only the particular disputes referred to in the Objection Notice that have not been resolved by Parent and the Company and shall determine such disputed amounts, the Final Closing Statement, and Adjusted Shareholders' Equity in accordance with the provisions of this Agreement. Upon reaching its determination of the Final Closing Statement and Adjusted Shareholders' Equity based on its determination of the disputed items, the Independent Accounting Firm shall deliver a copy of its calculation of the Final Closing Statement and Adjusted Shareholders' Equity to Parent and the Company. The determination of the Independent Accounting Firm shall be made within twenty (20) days after its engagement (which engagement shall be made no later than five (5) days after the end of the Negotiation Period) and shall be final and binding on all the parties. No party or its affiliates shall seek further recourse to courts, other tribunals or otherwise, other than to enforce the final decision of the Independent Accounting Firm as to the determination of the Final Closing Statement and Adjusted Shareholders' Equity. The aggregate fees, expenses and costs of the Independent Accounting Firm shall be borne (i) by Parent, if the difference, in absolute value terms, between Adjusted Shareholders' Equity as finally determined and Adjusted Shareholders' Equity set forth in the Objection Notice is greater than the difference, in absolute value terms, between Adjusted Shareholders' Equity as finally determined and Adjusted Shareholders' Equity set forth in the Final Closing Statement as delivered by the Company to Parent and (ii) otherwise by the Company, in the form of a reduction to Adjusted Shareholders' Equity for purposes of calculating the adjustment to the Exchange Ratio pursuant to Section 1.13. For the avoidance of doubt, the dispute resolution process contemplated by Section 1.12(e) and Section 1.12(f) shall

be only to determine the disputed items reflected on the Final Closing Statement and necessary to the calculation of Adjusted Shareholders' Equity as of the Shareholders' Equity Measuring Date, regardless of the date on which the Independent Accounting Firm delivers its calculation.

                             1.13      Exchange Ratio Adjustment.   

                             (a)         If Adjusted Shareholders' Equity, as finally determined pursuant to Section 1.12, is greater than or equal to $80,000,000, there shall be no adjustment to the Exchange Ratio, and to the extent Adjusted Shareholders' Equity, as finally determined pursuant to Section 1.12, exceeds $80,000,000, the Company may, in accordance with Section 6.17, declare and pay a special cash dividend immediately prior to the Closing, in an amount not to exceed such excess.

                             (b)         If Adjusted Shareholders' Equity, as finally determined pursuant to Section 1.12, is less than $80,000,000, the Exchange Ratio shall be reduced by the Exchange Ratio Reduction Amount.

                             (c)           For purposes of this Agreement (i) the term "Exchange Ratio Reduction Amount" shall mean an amount, rounded to the ten-thousandth decimal point, equal to (A) the Shareholders' Equity Shortfall, divided by (B) the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Cancelled Shares), divided by (C) the Parent Share Closing Price and (ii) the term "Shareholders' Equity Shortfall" shall mean the absolute value of the amount by which Adjusted Shareholders' Equity, as finally determined pursuant to Section 1.12, is less than $80,000,000.

ARTICLE II

EXCHANGE OF SHARES

                             2.1        Parent to Make Merger Consideration Available.   At or prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with an exchange agent designated by Parent and reasonably acceptable to the Company (the "Exchange Agent"), for the benefit of the holders of Old Certificates, for exchange in accordance with this Article II, (a) certificates or, at Parent's option, evidence of shares in book-entry form, representing the shares of Parent Common Stock (collectively, referred to herein as "New Certificates"), to be delivered to the holders of Company Common Stock pursuant to Section 1.5, and (b) any cash in lieu of fractional shares required to be paid to holders of Company Common Stock pursuant to this Article II (such New Certificates and cash, together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Exchange Fund").

                             2.2        Exchange of Shares.   

                             (a)         As promptly as practicable after the Effective Time, but in no event later than five (5) business days thereafter, Parent shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of Company Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive the Merger Consideration pursuant to Article I, (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall

pass, only upon proper delivery of the Old Certificates to the Exchange Agent (the "Letter of Transmittal") and (ii) instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of Parent Common Stock and any cash in lieu of fractional shares which the shares of Company Common Stock represented by such Old Certificates shall have been converted into the right to receive pursuant to this Agreement, as well as any dividends or distributions to be paid in respect thereof pursuant to Section 2.2(b). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, accompanied by a properly completed Letter of Transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate representing that number of whole shares of Parent Common Stock to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Article I and (ii) a check representing the amount of (A) any cash in lieu of fractional shares that such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II and (B) any dividends or distributions that the holder presenting such Old Certificate or Old Certificates has the right to receive pursuant to this Section 2.2, and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any Merger Consideration, dividends or distributions or cash in lieu of fractional shares payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the Merger Consideration and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

                             (b)         No dividends or other distributions declared with respect to Parent Common Stock shall be paid to the holder of any unsurrendered Old Certificate until such holder shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of Parent Common Stock that the shares of Company Common Stock represented by such Old Certificate have been converted into the right to receive.

                             (c)           If any New Certificate representing shares of Parent Common Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of Parent Common Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of Parent and the Exchange Agent that such Tax has been paid or is not payable.

                             (d)          After the Effective Time, there shall be no transfers on the stock transfer books of the Company of the shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Old

Table of Contents

Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration as provided in this Article II.

                             (e)          Notwithstanding anything to the contrary contained herein, no New Certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Parent. In lieu of the issuance of any such fractional share, Parent shall pay to each former holder of Company Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing price per share of Parent Common Stock on the NASDAQ Global Select Market (the "NASDAQ") as reported by www.nasdaq.com for the consecutive period of five (5) full trading days immediately preceding (but not including) the date that is the second (2nd) business day prior to the Closing Date (or, if not reported therein, in another authoritative source mutually agreed upon by Parent and the Company) (the "Parent Share Closing Price") by (ii) the fraction of a share (after taking into account all shares of Company Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

                             (f)           Any portion of the Exchange Fund that remains unclaimed by the holders of Company Common Stock for six (6) months after the Effective Time shall be delivered to the Surviving Corporation. Any former holders of Company Common Stock who have not theretofore exchanged their Old Certificates in compliance with this Article II shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration, cash in lieu of any fractional shares and any unpaid dividends and distributions on the Parent Common Stock deliverable in respect of each former share of Company Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Company, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

                             (g)          Parent shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, cash dividends or distributions payable pursuant to Section 2.2(b) or any other amounts otherwise payable pursuant to this Agreement to any holder of Company Common Stock or Company Equity Awards such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, as the case may be, and paid over to the appropriate governmental authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder in

respect of which the deduction and withholding was made by Parent or the Exchange Agent, as the case may be.

                             (h)         In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if reasonably required by Parent or the Exchange Agent, the posting by such person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the Merger Consideration and any cash in lieu of fractional shares, deliverable in respect thereof pursuant to this Agreement, and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(b).

                             (i)           Subject to the terms of this Agreement, Parent, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (i) the validity of any Letter of Transmittal and compliance by any holder of Company Common Stock with the procedures and instructions set forth herein and therein, (ii) the issuance and delivery of the whole number of shares of Parent Common Stock into which shares of Company Common Stock are converted in the Merger and (iii) the method of payment of cash in lieu of fractional shares of Parent Common Stock.

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

              Except as disclosed in the applicable section of the disclosure schedule delivered by the Company to Parent concurrently herewith (the "Company Disclosure Schedules"); provided that (i) no such item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (ii) the mere inclusion of an item in the Company Disclosure Schedules as an exception to a representation or warranty shall not be deemed an admission by the Company that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect and (iii) any disclosures made with respect to a section of Article III shall be deemed to qualify (a) any other section of Article III specifically referenced or cross-referenced and (b) other sections of Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections, the Company hereby represents and warrants to Parent as follows:

                             3.1        Corporate Organization.   

                             (a)         The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Washington, and is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended ("BHC Act"). The Company has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted. The Company is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the

business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Company. As used in this Agreement, the term "Material Adverse Effect" means, with respect to Parent, the Company or the Surviving Corporation, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, liabilities, results of operations or condition (financial or otherwise) of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles ("GAAP") or applicable regulatory accounting requirements or the enforcement, implementation or interpretation thereof, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, including any disruption in any financial, banking or securities markets in general and any decline in the price of any market index or any change in prevailing interest rates, (D) changes relating to or arising out of the public disclosure of this Agreement or of the transactions contemplated hereby (provided that this exception shall not apply for purposes of the representations and warranties in Section 3.3(b) or Section 4.3(b)), (E) a failure, in and of itself, to meet earnings projections or internal financial forecasts, but not including any underlying causes thereof, or changes in the trading price of Company Common Stock or Parent Common Stock (as applicable), in and of itself, but not including any underlying causes thereof or (F) actions that are taken with the express prior written consent of the other party in contemplation of the transactions contemplated hereby; except, with respect to subclauses (A), (B), or (C), to the extent that the effects of such change are disproportionately adverse to such party and its Subsidiaries, taken as a whole, as compared to other companies in the industries in which such party and its Subsidiaries operate) or (ii) the ability of such party to consummate the transactions contemplated hereby. As used in this Agreement, the word "Subsidiary" when used with respect to any person, means any corporation, partnership, limited liability company, bank, trust, association, joint venture or other organization, whether incorporated or unincorporated, or person of which (i) such first person directly or indirectly owns or controls at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions or (ii) such first person is or directly or indirectly has the power to appoint a general partner, manager or managing member or others performing similar functions. True and complete copies of the Amended and Restated Articles of Incorporation of the Company (the "Company Articles") and the Amended and Restated Bylaws of the Company (the "Company Bylaws"), as in effect as of the date of this Agreement, have previously been made available by the Company to Parent. The Company is not in violation of any of the provisions of the Company Articles or the Company Bylaws.

                             (b)          Each Subsidiary of the Company (a "Company Subsidiary") (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law,

in good standing in all jurisdictions (whether federal, state, local or foreign) in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary and in which the failure to be so licensed or qualified or in good standing would reasonably be expected, either individually or in the aggregate, to have a Material Adverse Effect on the Company and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of any Subsidiary of the Company to pay dividends or distributions, except in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities. The deposit accounts of each Subsidiary of the Company that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the "FDIC") through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950) to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened.

No Subsidiary of the Company owns any capital stock of the Company. Neither the Company nor any of its Subsidiaries is required to file with or furnish to the SEC any reports.

                             (b)          Other than the Voting Agreements, there are no voting trusts, shareholder agreements, proxies or other agreements in effect to which the Company or any of its Subsidiaries is a party with respect to the voting or transfer of the Company Common Stock, capital stock or other voting or equity securities or ownership interests of the Company or granting any shareholder or other person any registration rights.

                             (a)          Parent and the Company shall promptly prepare and file with the SEC the Proxy Statement, and Parent shall promptly prepare and file with the SEC the S-4, in which the Proxy Statement will be included as a prospectus. Each of Parent and the Company shall use their reasonable best efforts to have the S-4 declared effective under the Securities Act as promptly as practicable after such filing, and the Company shall thereafter mail or deliver the Proxy Statement to its shareholders. Parent shall also use its reasonable best efforts to obtain all necessary state securities law or "Blue Sky" permits and approvals required to carry out the transactions contemplated by this Agreement. The Company shall furnish all information concerning the Company and the holders of Company Common Stock as may be reasonably requested by Parent in connection with any of the foregoing.

                             (b)         The parties hereto shall cooperate with each other and use their reasonable best efforts to promptly (and in the case of the applications, notices, petitions and filings in respect of the Requisite Regulatory Approvals, within thirty (30) business days of the date of this Agreement) prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and Governmental Entities which are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such Governmental Entities. Parent and the Company shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to the Company or Parent, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this

A-48

Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement, and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated herein, subject to applicable law.

                             (c)           Each of Parent and the Company shall use its reasonable best efforts to resolve any objections that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing or anything to the contrary contained in this Agreement, under no circumstances shall Parent or any of its Subsidiaries be required, and the Company and its Subsidiaries shall not be permitted (without Parent's written consent), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of Governmental Entities that would reasonably be expected to be materially burdensome on, or impair in any material respect the benefits of the transactions contemplated by this Agreement to, Parent, the Surviving Corporation or their Subsidiaries, or have a material and adverse effect on Parent, the Surviving Corporation and their respective Subsidiaries, taken as a whole, or the Company and its Subsidiaries, taken as a whole (in each case, measured on a scale relative to the Company and its Subsidiaries, taken as a whole), after giving effect to the Merger (any of the foregoing, a "Materially Burdensome Regulatory Condition").

                             (d)          Parent and the Company shall, upon request, promptly furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger and the Bank Merger and the other transactions contemplated by this Agreement.

                             (e)          Parent and the Company shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained, or will be obtained subject to a Materially Burdensome Regulatory Condition, or that the receipt of any such approval will be materially delayed.

                             6.2        Access to Information; Confidentiality.   

                             (a)          Without limiting Parent's rights pursuant to Section 1.12(d), upon reasonable notice and subject to applicable laws, each of Parent and the Company, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, and each shall cooperate with the other

party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally, and, during such period, each of Parent and the Company shall, and shall cause its respective Subsidiaries to, make available to the other party (i) a copy of each report, schedule and other document filed or received by it during such period pursuant to the requirements of federal or state banking laws (other than reports or documents which Parent or the Company, as the case may be, is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Neither Parent nor the Company nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of Parent's or the Company's, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

                             (b)          Each of Parent and the Company shall hold all information furnished by or on behalf of the other party or any of such party's Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated March 29, 2018, between Parent and the Company (the "Confidentiality Agreement").

                             (c)           No investigation by either of the parties or their respective representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries' respective operations.

                             6.3        Shareholder Approval.   

                             (a)         The Company shall call a meeting of its shareholders (the "Company Meeting") to be held as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining the Requisite Company Vote required in connection with this Agreement and the Merger, and, if so desired and mutually agreed, upon other matters of the type customarily brought before a meeting of shareholders to approve a merger agreement or the transactions contemplated thereby, and the Company shall use its reasonable best efforts to cause the Company Meeting to occur as soon as reasonably practicable. The Company and its Board of Directors shall use their reasonable best efforts to obtain from the shareholders of the Company the Requisite Company Vote, including by communicating to its shareholders its recommendation (and including such recommendation in the Proxy Statement) that they adopt and approve this Agreement and the transactions contemplated hereby (the "Company Board Recommendation"), and shall not (i) withhold, withdraw, modify or qualify in a manner adverse to Parent the Company Board Recommendation, (ii) fail to make the Company Board Recommendation in the Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse

an Acquisition Proposal, (iv) fail to publicly, finally and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the Company Board Recommendation, in each case within ten (10) business days after such Acquisition Proposal is made public or any request by Parent to do so (which request may be made once per Acquisition Proposal, and any material change thereto) (or such fewer number of days as remains prior to Company Meeting), or (v) publicly propose to do any of the foregoing (any of the foregoing, a "Recommendation Change").

                             (b)          Notwithstanding anything in this Agreement to the contrary, prior to the time the Requisite Company Vote is obtained, the Board of Directors of the Company may make a Recommendation Change if and only if (i) the Company and its Subsidiaries and Representatives have complied with their obligations under Section 6.12, (ii) an unsolicited bona fide written Acquisition Proposal is made to the Company after the date of this Agreement by a third party, and such Acquisition Proposal is not withdrawn, (iii) the Board of Directors of the Company has concluded in good faith (after consultation with its outside legal counsel and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal, (iv) the Board of Directors of the Company has concluded in good faith (after consultation with its outside legal counsel) that failure to make a Recommendation Change would reasonably be expected to be inconsistent with the directors' fiduciary duties under applicable law, (v) prior to effecting the Recommendation Change, three (3) business days shall have elapsed since the Company has given written notice to Parent advising Parent that the Company intends to take such action and specifying in reasonable detail the reasons therefor, including the terms and conditions of, and the identity of the person making, any such Acquisition Proposal that is the basis of the Recommendation Change (it being understood that any amendment or change to any material term of such Acquisition Proposal shall require a new notice and the provisions of this Section 6.3(b) shall apply anew), (vi) during such three (3) business day period, the Company has considered, and engaged in good-faith discussions with Parent regarding, any adjustment or modification of the terms of this Agreement proposed by Parent and (vii) the Board of Directors of the Company, following such three (3)-business day period, again reasonably determines in good faith (after consultation with its outside legal counsel and financial advisors, and taking into account any adjustment or modification of the terms of this Agreement proposed by Parent and delivered to the Company in writing) that such Acquisition Proposal nonetheless continues to constitute a Superior Proposal and that failure to make a Recommendation Change would reasonably be expected to be inconsistent with the directors' fiduciary duties under applicable law.

                             (c)           The Company shall adjourn or postpone the Company Meeting if, as of the time for which such meeting is originally scheduled, there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting the Company has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Company Vote; provided, that no such adjournment or postponement shall delay the Company Meeting by more than ten (10) days from the prior-scheduled date or to a date on or after the fifth (5th) business day preceding the Termination Date. Except as described in the preceding sentence, the Company shall not adjourn or postpone the Company Meeting without Parent's written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

A-51

---

                             (d)          Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms (i) the Company Meeting shall be convened and this Agreement shall be submitted to the shareholders of the Company at the Company Meeting for the purpose of voting on the approval of this Agreement, and nothing contained herein shall be deemed to relieve the Company of such obligations, and (ii) the Company shall not submit to the vote of its shareholders any Acquisition Proposal or any transaction contemplated thereby.

                             6.4        Legal Conditions to Merger.   Subject in all respects to Section 6.1 of this Agreement, each of Parent and the Company shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other party to obtain) any consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is advisable or required to be obtained by the Company or Parent or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.

                             6.5        Stock Exchange Listing.   Parent shall file with the NASDAQ a notification form for the listing of all shares of Parent Common Stock to be delivered as Merger Consideration prior to the Effective Time and shall use its reasonable best efforts to cause such shares of Parent Common Stock to be listed on the NASDAQ, subject to official notice of issuance, prior to the Effective Time.

                             6.6        Employee Benefit Plans.   

                             (a)          During the period commencing at the Effective Time and ending on the first anniversary thereof, Parent shall provide, or cause to be provided, to each employee of the Company and its Subsidiaries who continues to be employed by Parent or its Subsidiaries immediately following the Effective Time (collectively, the "Continuing Employees"), while employed by Parent and its Subsidiaries after the Effective Time, (i) a base salary or wage rate that is no less favorable than the base salary or wage rate provided by the Company or any such Subsidiary, as applicable, to such Continuing Employee immediately prior to the Effective Time, (ii) an annual cash incentive compensation opportunity that is no less favorable than that provided to similarly situated employees of Parent and its Subsidiaries, and (iii) employee benefits that are substantially comparable in the aggregate to the employee benefits provided to similarly situated employees of Parent and its Subsidiaries; provided that Parent may satisfy its obligation under Section 6.6(a)(iii) by providing such Continuing Employees with employee benefits that are substantially comparable in the aggregate to the employee benefits provided by the Company or its Subsidiaries to such Continuing Employees immediately prior to the Effective Time until such time as such Continuing Employees commence participation in the applicable employee benefit plans of Parent and its Subsidiaries. Parent shall honor all change-in-control or severance agreements set forth in Section 6.6(a) of the Company Disclosure Schedules in accordance with their respective terms. In addition, Parent shall, or shall cause the Surviving Corporation or one of its Subsidiaries to, provide to each Continuing Employee whose employment terminates during the 12-month period following the Closing Date and who is not

party to an individual change-in-control or severance agreement with severance benefits equal to the severance benefits for which such Continuing Employee would be eligible under the severance plans or policies of Parent or its affiliates after providing recognition of service to the Company and its Subsidiaries in accordance with Section 6.6(b).

                             (b)          Following the Effective Time, Parent shall, or shall cause the Surviving Corporation to, cause any employee benefit plans sponsored or maintained by Parent or the Surviving Corporation or their Subsidiaries in which the Continuing Employees are eligible to participate following the Effective Time (collectively, the "Parent Plans") to recognize and provide credit for the service of each Continuing Employee with the Company and its Subsidiaries (and any predecessor thereto) prior to the Effective Time for purposes of eligibility, vesting and level of benefits under such Parent Plans; provided that such recognition of and credit for service shall not (i) apply for purposes of any Parent Plan that is a defined benefit retirement plan or any Parent Plan that provides retiree welfare benefits, (ii) operate to duplicate any benefits of a Continuing Employee with respect to the same period of service, or (iii) apply for purposes of any plan, program or arrangement (A) under which similarly situated employees of Parent and its Subsidiaries do not receive recognition or credit for prior service or (B) that is grandfathered or frozen, either with respect to level of benefits or participation. With respect to any Parent Plan that provides medical, dental or vision insurance benefits, for the plan year in which such Continuing Employee is first eligible to participate, Parent shall use commercially reasonable efforts to (1) cause any preexisting condition limitations or eligibility waiting periods under such plan to be waived with respect to such Continuing Employee to the extent such limitation would have been waived or satisfied under the Company Benefit Plan in which such Continuing Employee participated immediately prior to the Effective Time, and (2) credit each Continuing Employee for any co-payments, deductibles or out-of-pocket expenses incurred by such Continuing Employee and his or her eligible dependents in such plan year for purposes of any applicable co-payment, deductible and annual out-of-pocket expense requirements under any such Parent Plan. Parent and its Subsidiaries, as applicable, shall assume and honor, under the sick leave and vacation policies of the Company and its Subsidiaries as set forth on Section 6.6(b) of the Company Disclosure Schedules, the accrued but unused sick leave and vacation time of the Continuing Employees prior to the Effective Time.

                             (c)           If requested by Parent at least fifteen (15) days prior to the Effective Time, the Company shall cause any 401(k) plan sponsored or maintained by the Company or any of its Subsidiaries (each, a "Company 401(k) Plan") to be terminated effective as of the day immediately prior to the Closing Date and contingent upon the occurrence of the Closing. In the event that Parent so requests that any Company 401(k) Plan be terminated, (i) the Company shall provide Parent with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and approval by Parent) not later than two (2) days immediately preceding the Closing Date; and (ii) Parent shall permit (and, to the extent necessary, shall amend Parent's existing 401(k) Plan(s) to permit) the Continuing Employees who are participants in such Company 401(k) Plan and then actively employed to make rollover contributions of "eligible rollover distributions" (within the meaning of Section 401(a)(31) of the Code, inclusive of loans but excluding any shares of Parent Common Stock) in cash or notes (in the case of loans) in an amount equal to the full account balance distributed to any such Company Employee from the Company 401(k) Plan(s) to Parent's existing 401(k) plan(s).

Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Company Benefit Plan, Parent Plan or any other employee benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Corporation or any of its Subsidiaries or affiliates to amend, modify or terminate any particular Company Benefit Plan, Parent Plan or any other employee benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.9, nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than the parties hereto, including any current or former employee, officer, director or consultant of the Company or any of its Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

expend, on an annual basis, an amount in excess of 250% of the current annual premium paid as of the date hereof by the Company for such insurance (the "Premium Cap"), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation's good faith determination, provide the maximum coverage available at an annual premium not exceeding the Premium Cap. In lieu of the foregoing, Parent or the Company, in consultation with, but only upon the consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed), may (and at the request of Parent, the Company shall) obtain at or prior to the Effective Time a six-year "tail" policy under the Company's existing directors' and officers' liability insurance policy providing equivalent coverage to that described in the preceding sentence, if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.

                             (c)           The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Company Indemnified Party and his or her heirs and representatives. In the event the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties or assets to any person, then, and in each such case, the Surviving Corporation shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.7.

                             6.8        Additional Agreements.   In case at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of Parent, on the one hand, and a Subsidiary of the Company, on the other hand) or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be required or reasonably requested by Parent or the Company.

                             6.9        Advice of Changes.   Parent and the Company shall each promptly advise the other party of any fact, effect, change, event, circumstance, condition, occurrence or development that (i) has had or is reasonably likely, either individually or in the aggregate, to have a Material Adverse Effect on it or (ii) would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.9 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.

The Company shall give Parent the right to review and comment on all filings or responses to be made by the Company in connection with any such litigation, and the Company will in good faith take such comments into account, and no settlement of any such shareholder litigation shall be offered or agreed to without Parent's prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

                             6.11      Governance Matters.  

                             (a)         The directors of Parent at the Effective Time shall be the directors of the Surviving Corporation from and after the Effective Time until their successors are duly elected or appointed; provided, that effective immediately following the Effective Time, Parent shall take such action as is necessary to appoint Cheryl Bishop to the Board of Directors of the Surviving Corporation.

                             (b)         The officers of Parent at the Effective Time shall be the officers of the Surviving Corporation from and after the Effective Time until their successors are duly elected or appointed, together with such additional persons as may thereafter be elected or appointed.

                             6.12      Acquisition Proposals.  Except as expressly permitted by this Section 6.12, the Company agrees that it will not, and will cause each of its Subsidiaries and its and their respective officers, directors, employees, agents, advisors, financing sources, investment bankers, attorneys and other representatives (collectively, "Representatives") not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) disclose or provide any confidential or nonpublic information to, have or participate in any discussions with or otherwise cooperate in any way with, any person in connection with or relating to any Acquisition Proposal (including by affording access to the personnel, properties, books, records or assets of the Company or its Subsidiaries) or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.12) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, prior to the receipt of the Requisite Company Vote and subject to compliance with this Section 6.12, in the event the Company receives an unsolicited bona fide written Acquisition Proposal after the date of this Agreement that did not result from a breach of this Section 6.12, it may, and may permit its Subsidiaries and its and its Subsidiaries' Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if and only if its Board of Directors determines in good faith (after consultation with its outside legal counsel and financial advisors) that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal and that the failure to take such actions would reasonably be expected to be inconsistent with the

directors' fiduciary duties under applicable law; provided, further, that prior to providing any confidential or nonpublic information permitted to be provided pursuant to the foregoing proviso or participating in such negotiations or discussions, the Company shall have given Parent at least five (5) business days' prior written notice and shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with the Company. The Company shall provide Parent with a copy of any confidential or nonpublic information provided to any person pursuant to the prior sentence prior to or simultaneously with furnishing such information to such person (to the extent not previously provided). The Company will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than Parent with respect to any Acquisition Proposal and will request the return or destruction of any information provided to any such person in connection therewith. The Company will promptly (and within twenty-four (24) hours) advise Parent following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal) and will provide Parent an unredacted copy of such Acquisition Proposal and any draft agreements, proposals or other materials or correspondence received in connection with such inquiry or Acquisition Proposal, and will keep Parent apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal (including providing an unredacted copy of such amended or revised Acquisition Proposal and any further or revised draft agreements, proposals or other materials or correspondence received in connection with such inquiry or Acquisition Proposal). The Company shall enforce any existing confidentiality agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof and will not release any third party from, or waive any provisions of, any such agreements. As used in this Agreement, "Acquisition Proposal" shall mean, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of fifteen percent (15%) or more of the consolidated assets of the Company and its Subsidiaries or fifteen percent (15%) or more of any class of equity or voting securities of the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute fifteen percent (15%) or more of the consolidated assets of the Company, (ii) any tender offer (including a self-tender offer), exchange offer or other acquisition of equity or voting securities that, if consummated, would result in such third party beneficially owning fifteen percent (15%) or more of any class of equity or voting securities of the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute fifteen percent (15%) or more of the consolidated assets of the Company or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the Company or its Subsidiaries. As used in this Agreement, "Superior Proposal" means an unsolicited, bona fide written Acquisition Proposal made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination or acquisition transaction, all or substantially all of the consolidated assets of the Company and its Subsidiaries or all of the outstanding shares of Company Common Stock, and which the Board of Directors of the Company has in good faith determined (after consultation with its outside legal counsel and financial advisors, and taking

into account the terms and conditions of such Acquisition Proposal and this Agreement (as it may be proposed to be amended by Parent) and all legal, financial, timing, regulatory and other aspects of such Acquisition Proposal and the person making the proposal), to be more favorable, from a financial point of view, to the Company's shareholders than the Merger and the transactions contemplated by this Agreement (as it may be proposed to be amended by Parent) and to be reasonably likely to be consummated on a timely basis on the terms proposed.

                             6.14      Change of Method.  Parent shall be empowered, at any time prior to the Effective Time, to change the method or structure of effecting the combination of the Company and Parent (including the provisions of Article I), and the Company agrees to enter into such amendments to this Agreement as Parent may reasonably request to give effect to such restructuring; provided, however, that no such change or amendment shall (i) alter or change the amount or kind of the Merger Consideration provided for in this Agreement, (ii) adversely affect the Tax treatment of the Merger with respect to either party or its shareholders or (iii) impede or materially delay the consummation of the transactions contemplated by this Agreement or the receipt of the Requisite Regulatory Approvals.

                             6.15      Restructuring Efforts.  If the Company shall have failed to obtain the Requisite Company Vote at the duly convened Company Meeting or any adjournment or postponement thereof, unless this Agreement has been validly terminated in accordance with Section 8.1, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions provided for herein (it being understood that neither party shall have any obligation to alter or change any material terms, including the amount or kind of the Merger Consideration, in a manner adverse to such party or its shareholders or to agree to any change that would adversely affect the Tax treatment of the Merger with respect to such party or its shareholders) and/or resubmit this Agreement and the transactions contemplated hereby (or as restructured pursuant to this Section 6.15) to the Company's shareholders for approval.

                             6.16      Takeover Statutes.  None of the Company, Parent or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated

by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and thereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

                             6.17      Special Dividend.  After Adjusted Shareholders' Equity has been finally determined pursuant to Section 1.12, to the extent Adjusted Shareholders' Equity, as so determined, exceeds $80,000,000, the Board of Directors of the Company may, upon written notice to Parent and effective immediately prior to the Closing, declare and pay a special dividend in an amount not to exceed such excess.

TERMINATION AND AMENDMENT

                             8.1        Termination.   This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Requisite Company Vote:

                             (a)         by mutual written consent of Parent and the Company;

                             (b)         by either Parent or the Company, if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank Merger or any of the other transactions contemplated by this Agreement and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final nonappealable order, injunction, decree, or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, or any of the other transactions contemplated by this Agreement;

                             (c)           by either Parent or the Company, if the Merger shall not have been consummated on or before April 25, 2019 (the "Termination Date"), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or comply with the obligations, covenants and agreements of such party set forth herein;

                             (d)         by either Parent or the Company (provided, that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained herein), if there shall have been a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of the Company, in the case of a termination by Parent, or Parent, in the case of a termination by the Company, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by Parent, or Section 7.3, in the case of a termination by the Company, and which is not cured within thirty (30) days following written notice to the Company, in the case of a termination by Parent, or Parent, in the case of a termination by the Company, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the Termination Date);

with the vote contemplated by Section 6.3(a) having been taken and the Requisite Company Vote shall not have been obtained and (iii) prior to the Company Meeting, the Company shall have received a Superior Proposal which did not result from a breach of Section 6.3 or Section 6.12 and the Board of Directors of the Company shall have determined to enter into a definitive agreement providing for such Superior Proposal upon termination of this Agreement in accordance with this Section 8.1(e) and shall have entered into such agreement concurrently with such termination; provided, that (x) following such Company Meeting (including any postponements or adjournments thereof) and prior to such termination, the Company and the Board of Directors of the Company shall have complied with their respective obligations pursuant to Sections 6.3(b)(v), 6.3(b)(vi) and 6.3(b)(vii), which shall be deemed to apply to a termination pursuant to this Section 8.1(e) mutatis mutandis (it being understood that references to "Recommendation Change" therein shall, for purposes of this clause (x), be deemed to be references to a termination pursuant to this Section 8.1(e)) and (y) concurrently with and as a condition to the effectiveness of such termination the Company shall pay Parent the Termination Fee pursuant to Section 8.2(d);

                             (f)           by Parent if the Company Meeting (including any postponements or adjournments thereof) shall have concluded with the vote contemplated by Section 6.3(a) having been taken and the Requisite Company Vote shall not have been obtained; or

                             (g)         by Parent, prior to the Requisite Company Vote having been obtained, if the Company or the Board of Directors of the Company shall have (i) made a Recommendation Change or (ii) breached its obligations under Section 6.3 or 6.12 in any material respect.

                             8.2        Effect of Termination.  

                             (a)         In the event of termination of this Agreement by either Parent or the Company as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of Parent, the Company, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Section 6.2(b) (Access to Information; Confidentiality), Section 6.13 (Public Announcements), Section 8.1 (Termination), this Section 8.2 (Effect of Termination) and Article IX (General Provisions) shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither Parent nor the Company shall be relieved or released from any liabilities or damages arising out of its fraud or willful and material breach of any provision of this Agreement.

                             (b)         In the event that, after the date of this Agreement and prior to the termination of this Agreement, (i) a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of the Company or shall have been made directly to the shareholders of the Company, or any person shall have publicly announced an Acquisition Proposal, with respect to the Company, (ii) thereafter this Agreement is terminated (A) by either Parent or the Company pursuant to Section 8.1(c) (if the Requisite Company Vote has not theretofore been obtained but all other conditions set forth in Sections 7.1 and 7.3 had been satisfied or were capable of being satisfied prior to such termination) or (B) by Parent (x) pursuant to Section 8.1(d) or (y) pursuant to Section

8.1(f), and (iii) prior to the date that is twelve (12) months after the date of such termination, the Company enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then the Company shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Parent, by wire transfer of same-day funds, a fee equal to $7,750,000 (the "Termination Fee"); provided, that for purposes of this Section 8.2(b), all references in the definition of Acquisition Proposal to "fifteen percent (15%)" shall instead refer to "fifty percent (50%)."

                             (c)           In the event that this Agreement is terminated by Parent pursuant to Section 8.1(g), then the Company shall pay Parent, by wire transfer of same day funds, the Termination Fee within two business days of the date of termination.

                             (d)         In the event that this Agreement is terminated by the Company pursuant to Section 8.1(e), then the Company shall, concurrently with and as a condition to such termination, pay Parent the Termination Fee by wire transfer of same day funds.

                             (e)         The Company acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails to pay the amount due pursuant to this Section 8.2 when required, and, in order to obtain such payment, Parent commences a suit which results in a judgment against the Company for the Termination Fee or any portion thereof, the Company shall pay the costs and expenses of Parent (including attorneys' fees and expenses) in connection with such suit. In addition, if the Company fails to pay the amounts payable pursuant to this Section 8.2 when required, then the Company shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the "prime rate" published in The Wall Street Journal on the date such payment was required to be made plus 300 basis points for the period commencing as of the date that such overdue amount was originally required to be paid. The amounts payable by the Company pursuant to this Section 8.2 constitute liquidated damages and not a penalty, and, except in the case of fraud or willful and material breach of this Agreement, shall be the sole monetary remedy of Parent in the event of a termination of this Agreement specified in such section. In no event shall the Company be required to pay the Termination Fee more than once.

                             8.3        Amendment.   Subject to compliance with applicable law, this Agreement may be amended by the parties hereto, at any time before or after receipt of the Requisite Company Vote; provided, however, that after the receipt of the Requisite Company Vote, there may not be, without further approval of such shareholders, any amendment of this Agreement that requires such further approval under applicable law.

Board of Directors
Skagit Bancorp, Inc.
301 East Fairhaven Avenue
Burlington, WA 98233

Ladies and Gentlemen:

        Skagit Bancorp, Inc. ("Company") and Banner Corporation ("Parent") are proposing to enter into an Agreement and Plan of Merger (the "Agreement") pursuant to which Company will, subject to the terms and conditions set forth in the Agreement, merge with and into Parent with Parent being the surviving entity (the "Merger"). Pursuant to the terms and conditions of the Agreement, at the Effective Time, each share of Company's common stock, no par value ("Company Common Stock"), issued and outstanding immediately prior to the Effective Time, except for certain shares of Company Common Stock as specified in the Agreement, will be converted into and become the right to receive 5.6664 shares (the "Exchange Ratio") of Parent common stock, par value $0.01 per share ("Parent Common Stock"), subject to possible adjustment as set forth in the Agreement. The Agreement provides, generally, that if the Company's Adjusted Shareholders' Equity (i) is greater than or equal to $80,000,000, there shall be no adjustment to the Exchange Ratio, and to the extent Adjusted Shareholders' Equity exceeds $80,000,000, Company may declare and pay a special cash dividend immediately prior to the Closing, in an amount not to exceed such excess, or (ii) is less than $80,000,000, the Exchange Ratio shall be reduced by the Exchange Ratio Reduction Amount. Capitalized terms used herein without definition shall have the meanings assigned to them in the Agreement. The terms and conditions of the Merger are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Company Common Stock.

        Sandler O'Neill & Partners, L.P. ("Sandler O'Neill", "we" or "our"), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated July 23, 2018; (ii) certain publicly available financial statements and other historical financial information of Company that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of Parent that we deemed relevant; (iv) certain internal financial projections for Company for the year ending December 31, 2018, as provided by the senior management of Company, as well as a long-term earnings per share growth rate and dividend payout ratio for the years thereafter, as directed by the senior management of Company; (v) publicly available consensus analyst net income estimates for Parent for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate

for the years thereafter and dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Parent; (vi) the pro forma financial impact of the Merger on Parent based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as estimated revenue impacts following the closing of the Merger, as directed by the senior management of Parent; (vii) the publicly reported historical price and trading activity for Parent Common Stock, including a comparison of certain stock market information for Parent Common Stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded; (viii) a comparison of certain financial information for Company and Parent with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the banking industry (on a nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the management of Company and its representatives the business, financial condition, results of operations and prospects of Company and held similar discussions with certain members of the management of Parent and its representatives regarding the business, financial condition, results of operations and prospects of Parent.

        In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by us from public sources, that was provided to us by Company or Parent or their respective representatives, or that was otherwise reviewed by us, and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have relied on the assurances of the respective managements of Company and Parent that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Company or Parent or any of their respective subsidiaries, nor have we been furnished with any such evaluations or appraisals. We render no opinion or evaluation on the collectability of any assets or the future performance of any loans of Company or Parent. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Company or Parent, or of the combined entity after the Merger, and we have not reviewed any individual credit files relating to Company or Parent. We have assumed, with your consent, that the respective allowances for loan losses for both Company and Parent are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

        In preparing its analyses, Sandler O'Neill used certain internal financial projections for Company for the year ending December 31, 2018, as provided by the senior management of Company, as well as a long-term earnings per share growth rate and dividend payout ratio for the years thereafter, as directed by the senior management of Company. In addition, Sandler O'Neill used publicly available consensus analyst net income estimates for Parent for the second half of the year ending December 31, 2018 and the full year ending December 31, 2019, as well as a long-term earnings per share growth rate for the years thereafter and dividend payout ratio for the years ending December 31, 2018 through December 31, 2022, as directed by the senior management of Parent. Sandler O'Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as estimated revenue impacts following the closing of the Merger, as directed by the senior management of Parent. With respect to the foregoing information, the respective senior managements of Company and Parent confirmed to us that such information reflected (or, in the case of the publicly available consensus analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgments of those respective managements as to the future financial performance of Company and Parent, respectively, and the

other matters covered thereby, and we assumed that the future financial performance reflected in such information would be achieved. We express no opinion as to such information, or the assumptions on which such information is based. We have also assumed that there has been no material change in the respective assets, financial condition, results of operations, business or prospects of Company or Parent since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analysis that Company and Parent will remain as going concerns for all periods relevant to our analysis.

        We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Company, Parent, the Merger or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with your consent, we have relied upon the advice that Company has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

        Our opinion is necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of Parent Common Stock at any time or what the value of Parent Common Stock will be once it is actually received by the holders of Company Common Stock.

        We have acted as Company's financial advisor in connection with the Merger and will receive a fee for our services, which fee is contingent upon closing of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the transaction fee which will become payable to Sandler O'Neill on the day of closing of the Merger. Company has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. In the two years preceding the date hereof we have not provided any other investment banking services to Company, nor has Sandler O'Neill provided any investment banking services to Parent in the two years preceding the date hereof. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Parent and its affiliates. We may also actively trade the equity and debt securities of Parent and its affiliates for our own account and for the accounts of our customers.

        Our opinion is directed to the Board of Directors of Company in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Company as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Company Common Stock and does not address the underlying business decision of Company to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for Company or the effect of any other transaction in which Company might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received

in the Merger by any officer, director or employee of Company or Parent, or any class of such persons, if any, relative to the compensation to be received in the Merger by any other shareholder. This opinion has been approved by Sandler O'Neill's fairness opinion committee. This opinion may not be reproduced without Sandler O'Neill's prior written consent; provided, however, Sandler O'Neill will provide its consent for the opinion to be included in regulatory filings to be completed in connection with the Merger.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to holders of Company Common Stock from a financial point of view.

not commence the proceeding within the sixty-day period, it shall pay each dissenter whose demand remains unsettled the amount demanded.

(2)

The court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

VOTING AND SUPPORT AGREEMENT

        This Voting and Support Agreement (this "Agreement"), dated as of July 25, 2018, is entered into by and between Banner Corporation, a Washington corporation ("Parent") and the undersigned (the "Shareholder"), a shareholder of Skagit Bancorp, Inc., a Washington corporation (the "Company").

        WHEREAS, subject to the terms and conditions of the Agreement and Plan of Merger (as the same may be amended, supplemented or modified, the "Merger Agreement"), dated as of the date hereof, between Parent and the Company, the Company will be merged with and into Parent, with Parent as the surviving corporation (the "Merger");

        WHEREAS, as of the date of this Agreement, the Shareholder owns beneficially or of record, and has the power to vote or direct the voting of, certain shares of common stock, no par value, of the Company ("Common Stock") (all such shares, the "Existing Shares");

        WHEREAS, the parties to this Agreement believe that the future success and profitability of Parent and its subsidiaries following the Merger, including without limitation, Banner Bank (the "Combined Bank"), requires that the Shareholder be subject to the restrictions set forth herein, including with respect to his or her specified involvement with a Competing Business (as defined herein) for a period of two (2) years after the consummation of the Merger; and

        WHEREAS, as a condition and inducement for Parent to enter into the Merger Agreement, Parent has required that the Shareholder, in the Shareholder's capacity as a shareholder of the Company, enter into this Agreement, and the Shareholder has agreed to enter into this Agreement.

        NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

        1.    Definitions.    Capitalized terms not defined in this Agreement have the meaning assigned to those terms in the Merger Agreement. The following definitions also apply to this Agreement:

        a.    Competing Business.    "Competing Business" means any depository, commercial and/or consumer lending, wealth management or trust business company or holding company thereof (including without limitation, any start-up bank or bank in formation) that has a branch office or other office in, or does material business in, the Covered Area; provided, that Competing Business shall not include the existing business activities of the Shareholder as set forth on Schedule A hereto.

        b.    Covered Area.    "Covered Area" means the counties in the State of Washington in which the Company's subsidiary bank has commercial banking offices or banking subsidiaries of Parent have commercial banking offices, in each case as of the date hereof.

        c.    Term.    "Term" means the period of time beginning on the Closing Date and ending two (2) years after the Closing Date.

        d.    Beneficial Ownership.    For purposes of this Agreement, the terms "beneficial owner," "beneficially own" and "beneficial ownership" shall have the meaning set forth in Rule 13d-3 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

        2.    Effectiveness; Termination.    This Agreement shall be effective upon signing. If the Merger Agreement is terminated for any reason in accordance with its terms, this Agreement shall automatically terminate and be null and void and of no effect; provided that (i) this Section 2 and Sections 14 through 19 hereof shall survive any such termination and (ii) such termination shall not

D-1

Table of Contents

relieve any party of any liability or damages resulting from any willful or material breach of any of its representations, warranties, covenants or other agreements set forth herein.

        3.    Participation in Competing Business.    Except as provided in Section 7 and Section 8, during the Term, the Shareholder shall not become involved with or serve, directly or indirectly, a Competing Business in any manner, including without limitation as a shareholder, member, partner, director, officer, manager, investor, organizer, founder, employee, advisor, consultant, agent, or representative, or otherwise becoming involved in any manner in the organization, pre-opening phases, or the formation of such Competing Business; provided, that for the avoidance of doubt, the restrictions set forth herein shall not prevent the Shareholder from using services of any Competing Business that are generally available to the public.

        4.    No Solicitation.    During the Term, the Shareholder shall not, directly or indirectly, (a) solicit or hire, or attempt to solicit or hire, any employees of Parent, the Company or any of their respective subsidiaries, including the Combined Bank (or individual who was an employee of Parent, the Company or any of their respective subsidiaries, including the Combined Bank, within the year preceding such solicitation) to participate, as an employee or otherwise, in any manner in a Competing Business or to resign or terminate his or her employment with Parent, the Company or any of their respective subsidiaries, including the Combined Bank, or (b) solicit or attempt to solicit any customers of Parent, the Company or any of their respective subsidiaries, including the Combined Bank, who Shareholder is aware is or was as of the Closing Date a customer of Parent, the Company or any of their respective subsidiaries, including the Combined Bank, to transfer their business to a Competing Business or to cease conducting business with Parent, the Company or any of their respective subsidiaries, including the Combined Bank. Solicitation prohibited under this section includes solicitation by any means, including, without limitation, meetings, letters or other mailings and electronic communications of any kind. Nothing in this Section 4 shall prohibit the Shareholder from hiring an employee of Parent, the Company or any of their respective subsidiaries who responds to a public advertisement or general solicitation disseminated by Shareholder which is not specifically targeted at such employee or targeted at employees of Parent, the Company or their respective Subsidiaries generally.

        5.    Confidential Information.    During the Term, the Shareholder shall maintain the confidentiality of and shall not use or disclose any confidential information of Parent, the Company or any of their respective subsidiaries obtained by the Shareholder or its affiliates while serving as a director, officer, employee or shareholder of the Company or any of its subsidiaries. For purposes of this Agreement, "confidential information" means any information and material of or relating to Parent or the Company or any of their respective subsidiaries, including proprietary information and trade secrets, and any and all information disclosed to or known by the Shareholder or its affiliates as a consequence of any such person's employment, services or status as a director, officer, employee or shareholder of the Company or any of its subsidiaries, but does not include (a) information that is or becomes generally available to the public other than as a result of an unauthorized disclosure; (b) information that was in the Shareholder's possession on a non-confidential basis prior to the Shareholder serving as a director, officer or employee of, or becoming a shareholder of, the Company or its subsidiaries, or information received by the Shareholder from another person without any limitations on disclosure, but only if the Shareholder had no reason to believe that the other person was prohibited from using or disclosing such information by a contractual or fiduciary obligation; or (c) information that was independently developed by the Shareholder without use of or reference to any confidential information of Parent, the Company or their respective subsidiaries. If the Shareholder is required by any governmental authority (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process), to disclose any confidential information, the Shareholder shall provide Parent with prompt notice of any such requirement and shall provide, at Parent's expense, such reasonable cooperation as Parent may request so that Parent may seek a protective order or other appropriate remedy. If, in the absence of a

D-2

---

Table of Contents

protective order or other remedy or the receipt of a written waiver from Parent, the Shareholder is nonetheless legally compelled to disclose confidential information to any governmental authority, the Shareholder may, without liability hereunder, disclose to such governmental authority only that portion of confidential information which is legally required to be disclosed; provided, that the Shareholder exercises reasonable efforts to preserve the confidentiality of such confidential information, including, without limitation, by reasonably cooperating with Parent, at its expense, to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded to such confidential information by such governmental authority.

        6.    Defend Trade Secrets Act.    Pursuant to the Defend Trade Secrets Act of 2016, 18 U.S.C. § 1833(b), the Shareholder will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (a) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (b) in a complaint or other document filed in a proceeding, if such filing is made under seal. In addition, a Shareholder who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the Shareholder and use the trade secret information in the proceeding, if the Shareholder (y) files any document containing the trade secret under seal and (z) does not disclose the trade secret, except pursuant to court order.

        7.    Outside Covered Area; Requests for Waivers or Permission.    Nothing in Section 3 prevents the Shareholder from becoming involved with, as a shareholder, member, partner, director, officer, manager, investor, organizer, founder, employee, consultant, agent, representative, or otherwise, a business that has no office or operations in the Covered Area. Prior to engaging in any manner in a Competing Business, the Shareholder may request in writing that Parent waive the restrictions set forth in this Agreement with respect to a particular proposed activity. If Parent determines that such activity is acceptable, Parent may provide the Shareholder with a written consent to engage in such activity, and such activity shall thereafter not be deemed a Competing Business.

        8.    Passive Interest.    Nothing in Section 3 prevents the Shareholder from passively acquiring, directly or indirectly, individually or in the aggregate 2% or less of the outstanding stock or voting securities of a Competing Business.

        9.    Reasonableness of Restrictions.    The Shareholder acknowledges and agrees that the covenants set forth above represent only a limited restraint and allow the Shareholder to pursue his or her occupation without unreasonable or unfair restrictions. The Shareholder acknowledges that the limitations of length of time, geography and scope of activity agreed to in this Agreement are reasonable because, among other things: (a) the Company, Parent and their respective subsidiaries are engaged in a highly competitive industry; (b) the Shareholder has had unique access to the trade secrets and know-how of the Company, Parent and their respective subsidiaries, including the plans and strategy (and, in particular, the competitive strategy) of the Combined Bank; (c) the Shareholder will receive the benefit of a substantial premium for the Shareholder's Shares in the Merger, and will have a shared interest with Parent, as a continuing shareholder of Parent, in preserving the benefits to Parent of the Merger for which Parent will have paid good and valuable consideration as contemplated by the Merger Agreement; and (d) this Agreement provides no more protection than is necessary to protect Parent's interests in the Company's and its subsidiaries' goodwill, trade secrets and confidential information.

        10.    Voting Agreement.    From the date hereof until the earlier of (a) the Closing and (b) the termination of the Merger Agreement in accordance with its terms (the "Support Period"), the Shareholder irrevocably and unconditionally hereby agrees that at any meeting (whether annual or special and each adjourned or postponed meeting) of the Company's shareholders, however called, or in connection with any written consent of the Company's shareholders, the Shareholder shall (i) appear

D-3

Table of Contents

at such meeting or otherwise cause all of his or her Existing Shares and all other shares of Common Stock or voting securities over which the Shareholder has acquired beneficial or record ownership after the date hereof and the power to vote or direct the voting of (including any shares of Common Stock acquired by means of purchase, dividend or distribution, or issued upon the exercise of any stock options to acquire Common Stock or the conversion of any convertible securities, or pursuant to any other equity awards or derivative securities (including any Company Equity Awards) or otherwise) (together with the Existing Shares, the "Shares"), as of the applicable record date, to be counted as present thereat for purposes of calculating a quorum, and (ii) vote or cause to be voted (including by proxy or written consent, if applicable) all such Shares (A) in favor of the approval of the Merger Agreement and the approval of the transactions contemplated thereby, including the Merger, (B) in favor of any proposal to adjourn or postpone such meeting of the Company's shareholders to a later date if there are not sufficient votes to approve the Merger Agreement, (C) against any action or proposal in favor of an Acquisition Proposal, without regard to the terms of such Acquisition Proposal, and (D) against any action, proposal, transaction or agreement that would reasonably be likely to (1) result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of the Shareholder contained in this Agreement, or (2) prevent, impede, interfere with, delay, postpone, discourage or frustrate the purposes of or adversely affect the consummation of the transactions contemplated by the Merger Agreement, including the Merger; provided, that the foregoing applies solely to the Shareholder in the Shareholder's capacity as a shareholder and, to the extent the Shareholder serves as a member of the board of directors or as an officer of the Company, nothing in this Agreement shall limit or affect any actions or omissions taken by the Shareholder solely in the Shareholder's capacity as such a director or officer. For the avoidance of doubt, the foregoing commitments apply to any Shares held by any trust, limited partnership or other entity holding Shares for which the Shareholder serves in any partner, shareholder or trustee capacity. To the extent the Shareholder does not control, by himself or herself, the determinations of such shareholder entity, the Shareholder agrees to exercise all voting or other determination rights the Shareholder has in such shareholder entity to carry out the intent and purposes of the Shareholder's support and voting obligations in this paragraph and otherwise set forth in this Agreement. The Shareholder covenants and agrees that, except for this Agreement, the Shareholder (x) has not entered into, and shall not enter into during the Support Period, any voting agreement or voting trust with respect to the Shares and (y) has not granted, and shall not grant during the Support Period, a proxy, consent or power of attorney with respect to the Shares except any proxy to carry out the intent of this Agreement. The Shareholder has not entered into and agrees not to enter into any agreement or commitment with any person the effect of which would be inconsistent with or otherwise violate the provisions and agreements set forth herein.

        11.    Transfer Restrictions Prior to the Merger.    The Shareholder hereby agrees that the Shareholder will not, during the Support Period, without the prior written consent of Parent, directly or indirectly, offer for sale, sell, transfer, assign, give, tender in any tender or exchange offer, pledge, encumber, hypothecate or similarly dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, encumbrance, hypothecation or other disposition of (by merger, by testamentary disposition, by operation of law or otherwise) or otherwise convey or dispose of, any of the Shares, or any interest therein, including the right to vote any Shares, as applicable (any of the foregoing, a "Transfer"); provided, that the Shareholder may (i) Transfer Shares for estate planning or philanthropic purposes so long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this Agreement and the Shareholder provides at least two (2) days' prior written notice (which shall include the written consent of the transferee agreeing to be bound by and comply with the provisions of this Agreement), in which case the Shareholder shall

remain responsible for any breach of this Agreement by such transferee, or (ii) surrender Shares to the Company in connection with the vesting, settlement or exercise of Company Equity Awards to satisfy any withholding for the payment of taxes incurred in connection with such vesting, settlement or exercise, or, in respect of Company Options, the exercise price thereon.

        12.    Representations of the Shareholder.    The Shareholder represents and warrants to Parent as follows: (a) the Shareholder has full legal right, capacity and authority to execute and deliver this Agreement, to perform the Shareholder's obligations hereunder and to consummate the transactions contemplated hereby; (b) this Agreement has been duly and validly executed and delivered by the Shareholder and constitutes a valid and legally binding agreement of the Shareholder, enforceable against the Shareholder in accordance with its terms, and no other action is necessary to authorize the execution and delivery of this Agreement by the Shareholder or the performance of the Shareholder's obligations hereunder; (c) the execution and delivery of this Agreement by the Shareholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof will not, conflict with or violate any law or result in any breach of or violation of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a Lien on any of the Shares pursuant to, any agreement or other instrument or obligation binding upon the Shareholder or the Shares, nor require any authorization, consent or approval of, or filing with, any Governmental Entity; (d) the Shareholder beneficially owns and has the power to vote or direct the voting of the Shares; and (e) the Shareholder beneficially owns the Shares free and clear of any proxy, voting restriction, adverse claim or other Lien (other than any restrictions created by this Agreement or under applicable federal or state securities laws); (f) the Shareholder has read and is familiar with the terms of the Merger Agreement; and (g) as of the date hereof, the Shareholder is the record or beneficial owner of, and has the power to vote or direct the voting of, not less than the number of Shares set forth on Schedule B hereto (the "Minimum Shares"). The Shareholder agrees that the Shareholder shall not take any action that would make any representation or warranty of the Shareholder contained herein untrue or incorrect or have the effect of preventing, impairing, delaying or adversely affecting the performance by the Shareholder of the Shareholder's obligations under this Agreement. The Shareholder agrees, without further consideration, to execute and deliver such additional documents and to take such further actions as are necessary or reasonably requested by Parent to confirm and assure the rights and obligations set forth in this Agreement.

        13.    Entire Agreement; Assignment.    The recitals are incorporated as a part of this Agreement. This Agreement and the Merger Agreement constitute the entire agreement among the parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, other than, if the Shareholder is an officer of the Company, with respect to any employment agreement between the Shareholder and the Company or its affiliates. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. This Agreement shall not be assigned by operation of law or otherwise and shall be binding upon and inure solely to the benefit of each party hereto; provided, however, that the rights under this Agreement are assignable by Parent to a majority-owned affiliate or any successor-in-interest of Parent, but no such assignment shall relieve Parent of its obligations hereunder.

        14.    Remedies/Specific Enforcement.    Each of the parties hereto agrees that this Agreement is intended to be legally binding and specifically enforceable pursuant to its terms and that Parent would be irreparably harmed if any of the provisions of this Agreement are not performed in accordance with its specific terms and that monetary damages would not provide adequate remedy in such event. Accordingly, in the event of any breach or threatened breach by the Shareholder of any covenant or obligation contained in this Agreement, in addition to any other remedy to which Parent may be

D-5

Table of Contents

entitled (including monetary damages), Parent shall be entitled to injunctive relief to prevent breaches or threatened breaches of this Agreement and to specifically enforce the terms and provisions hereof, and the Shareholder hereby waives any defense in any action for specific performance or an injunction or other equitable relief that a remedy at law would be adequate. The Shareholder further agrees that neither Parent nor any other person or entity shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this paragraph, and the Shareholder irrevocably waives any right the Shareholder may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

        15.    Governing Law and Enforceability.    This Agreement is governed by, and shall be interpreted in accordance with, the laws of the State of Washington, without regard to any applicable conflict of law principles. Each of the parties hereto (a) agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court of competent jurisdiction located in the State of Washington (the "Chosen Courts"), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (b) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (c) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (d) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (e) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 16.

        16.    Notice.    All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally, be e-mail or facsimile transmission (with confirmation), mailed by registered or certified mail (return receipt requested) or delivered by an express courier (with confirmation) if to the Shareholder, to the address, e-mail address or facsimile number, as applicable, set forth in Schedule B hereto, or if no such address, e-mail address or facsimile number is provided, then to the address of the Shareholder set forth in the shareholder register of the Company, and if to Parent, in accordance with Section 9.3 of the Merger Agreement.

        17.    Severability.    Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.    Indemnification of Directors and Officers

Washington Business Corporation Act

        Banner is organized under the WBCA which, in general, empowers Washington corporations to indemnify a person made a party to a threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative and whether formal or informal, other than an action by or in the right of the corporation, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another enterprise, against judgments, amounts paid in settlements, penalties, fines and reasonable expenses, including attorneys' fees, incurred in connection therewith if the person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation or its shareholders and, with respect to a criminal action or proceeding, if the person had no reasonable cause to believe his or her conduct was unlawful. Such indemnification is mandatory with respect to reasonable expenses for a director who is wholly successful on the merits or otherwise in the defending any proceeding. Washington corporations may not indemnify a person in connection with such proceedings if the person was adjudged to have received an improper personal benefit.

        The WBCA also empowers Washington corporations to provide similar indemnity to such a person in connection with actions or suits by or in the right of the corporation if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the interests of the corporation or its shareholders, unless the person was adjudged liable to the corporation.

        If authorized by the articles of incorporation of a Washington corporation or by a bylaw or resolution adopted by its shareholders, a Washington corporation may indemnify and advance expenses to the persons described above without regard to the limitations described above, provided that such indemnity will not cover acts or omissions of the person finally adjudged to be intentional misconduct or a knowing violation of law, conduct finally adjudged to involve a violation of WBCA Chapter 8, Section 310 (related to certain unlawful distributions), and any transaction with respect to which it was finally adjudged that the person received a benefit to which such person was not legally entitled.

        The WBCA also permits a Washington corporation to purchase and maintain on behalf of such persons insurance against liabilities incurred in such capacities. Banner has obtained a policy of directors' and officers' liability insurance.

        The WBCA further permits Washington corporations to limit the personal liability of directors for a breach of their fiduciary duty. However, the WBCA does not eliminate or limit the liability of a director for any of the following: (i) acts or omissions that involve intentional misconduct by a director or a knowing violation of law by a director; (ii) conduct violating WBCA Chapter 8, Section 310 (related to certain unlawful distributions); or (iii) any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.

Banner's Articles of Incorporation and Bylaws

        Banner's articles of incorporation limit the personal liability of directors to shareholders for monetary damages for conduct as a director except for under the circumstances required to be excepted under Washington law described above.

        Banner's articles of incorporation generally require Banner to indemnify directors, officers, employees and agents to the fullest extent legally possible under the WBCA. In addition, the articles of incorporation require Banner to similarly indemnify any such person who is or was serving at the

request of Banner as a director, officer, partner, trustee, employee or agent of another entity. Banner's articles of incorporation further provide for the advancement of expenses under certain circumstances.

Item 22.    Undertakings

        The undersigned registrant hereby undertakes:

        To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

•

to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;



•

to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and



•

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

        That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

        That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

        That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of

Table of Contents

any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

        That every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

        To respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

        To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
