GENERAL INFORMATION

PROXY STATEMENT

General Information

This proxy statement is being provided to stockholders of Western Alliance Bancorporation (“Company”) for solicitation of proxies on behalf of the Board of Directors of the Company for use at the Annual Meeting of Stockholders (“Annual Meeting”) to be held at the Company’s headquarters at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, at 11:00 a.m., local time, on Tuesday, June 12, 2018, and any and all adjournments thereof.

We use the SEC notice and access rule that allows us to furnish our proxy materials to our stockholders over the internet instead of mailing paper copies of those materials. As a result, beginning on or about April 27, 2018, we sent our stockholders by mail a notice of internet availability of proxy materials containing instructions on how to access our proxy materials over the internet and vote online. This notice is not a proxy card and cannot be used to vote your shares. You will not receive paper copies of the proxy materials unless you request the materials by following the instructions on the notice or on the website referred to on the notice. Using notice and access allows us to reduce our printing and mailing costs and the environmental impact of our proxy materials. The Company will pay all expenses incurred in this solicitation.

The Company is soliciting proxies by mail, over the internet and by telephone, and the Company’s directors, officers and employees may solicit proxies on behalf of the Company without additional compensation. In addition, the Company has retained Morrow Sodali, LLC of 470 West Ave. Stamford, Connecticut 06902, to assist in the solicitation of proxies for a fee of $9,000.00 plus disbursements based on out-of-pocket expenses, telecommunicators, directory assistance and related telephone expenses. Proxy solicitation materials will be furnished to fiduciaries, custodians and brokerage houses for forwarding to the beneficial owners of shares held in their names. The Company will, upon request, reimburse such parties for their reasonable expenses in forwarding proxy materials to beneficial owners.

Your proxy is being solicited by the Board of Directors of the Company. Your proxy will be voted as you direct; however, if no instructions are given on an executed and returned proxy, it will be voted FOR the election of the fourteen director nominees for a one year term, FOR the approval of our executive compensation, it will be voted EVERY YEAR regarding the frequency with which the Company will hold the non-binding vote on executive compensation, and FOR the ratification of our auditors.

If any other matters are properly brought before the Annual Meeting, the persons named in the proxy will vote the shares represented by such proxy on such matters in their discretion. The Company is required to file an annual report on Form 10-K for its 2017 fiscal year with the Securities and Exchange Commission (“SEC”). Stockholders may obtain, free of charge, a copy of our annual report on Form 10-K by visiting www.proxyvote.com or www.westernalliancebancorporation.com, or by writing to the Company at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, Attention: Corporate Secretary.

Voting Rights

Only stockholders of record at the close of business on April 16, 2018 (“Record Date”) are entitled to vote at the Annual Meeting and any adjournments thereof. On the Record Date, there were 105,857,628 shares of common stock outstanding and eligible to be voted at the Annual Meeting. Each holder of common stock shall have one vote for each share of common stock of the Company in the holder’s name on the Record Date.

Stockholders who do not plan to attend the Annual Meeting in person or who will attend the Annual Meeting but wish to vote by proxy may do so as follows:


•	Internet: going to www.proxyvote.com and following the online instructions. You will need information from your Notice of Internet Availability or proxy card, as applicable, to submit your proxy.


•	Telephone: calling 1-800-690-6903 and following the voice prompts. You will need information from your Notice of Internet Availability or proxy card, as applicable, to submit your proxy.


•	Mail (if you request to receive your proxy materials by mail): marking your vote on your proxy card, signing your name exactly as it appears on your proxy card, dating your proxy card, and returning it in the envelope provided.



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	1



Table of Contents

VOTING RIGHTS • QUORUM AND SUMMARY OF PROPOSALS

Stockholders who provide their proxy over the internet may incur costs, such as telephone and internet access charges, for which the stockholder is responsible. Eligible stockholders of record will not be able to provide their proxy through the internet or over the telephone after 11:59 p.m. Eastern Time on June 11, 2018. After such time, stockholders of record will only be able to vote by attending the Annual Meeting and voting in person.

A proxy may be revoked at any time before the shares represented by it are voted at the Annual Meeting by delivering to the Corporate Secretary of the Company a written revocation or a duly executed proxy bearing a later date (including a proxy given over the internet or by telephone), or by voting in person at the Annual Meeting. Attendance at the Annual Meeting without voting will not revoke a previously provided proxy.

If your shares are held in a brokerage account or by another nominee, you are considered the “beneficial owner” of shares held in “street name,” and these proxy materials are being forwarded to you by your broker or nominee (“record holder”) along with a voting instruction card. As the beneficial owner, you have the right to direct your record holder how to vote your shares, and the record holder is required to vote your shares in accordance with your instructions. If your shares are held by a broker, the broker will ask you how you want your shares to be voted. If you give the broker instructions, your shares will be voted as you direct.

If you do not give instructions, whether the broker can vote your shares depends on whether the proposal is considered “routine” or “non-routine” under New York Stock Exchange (“NYSE”) rules. If a proposal is routine, a broker or other entity holding shares for an owner in street name may vote on the proposal without voting instructions from the owner. If a proposal is non-routine, the broker or other entity may vote on the proposal only if the owner has provided voting instructions. A “broker non-vote” occurs when the broker or other entity is unable to vote on a proposal because the proposal is non-routine and the owner does not provide instructions. The Ratification of Auditor is the only proposal set forth in this proxy statement that is considered routine.

For each of the proposals to be considered at the Annual Meeting, abstentions and broker non-votes will have the following effect:

Proposal No. 1 – Election of Directors. Broker non-votes and abstentions will have no effect on this proposal.

Proposal No. 2 – Advisory (Non-Binding) Vote on Executive Compensation. Broker non-votes will have no effect on this proposal. Abstentions will have the same effect as votes against the proposal.

Proposal No. 3 – Advisory (Non-Binding) Vote on Frequency of Executive Compensation Votes. Broker non-votes will have no effect on this proposal. Abstentions will have the same effect as votes against the proposal.

Proposal No. 4 – Ratification of Auditor. Abstentions will have the same effect as votes against this proposal.

If your shares are held in the name of a bank or broker, your ability to provide a proxy over the internet or via the telephone will depend on the processes of your bank or broker. Therefore, we recommend that you follow the instructions on the form you receive.

Quorum and Summary of Proposals

The presence in person or by proxy of the holders of a majority of the shares of the capital stock of the corporation entitled to vote at the Annual Meeting is necessary to constitute a quorum at the meeting. Abstentions and broker non-votes will be treated as shares that are present, or represented and entitled to vote, for purposes of determining the presence of a quorum at the Annual Meeting. Our Board of Directors has recommended you vote “FOR” the director-nominees, "FOR" the approval of our executive compensation, "EVERY YEAR" regarding the frequency with which the Company will hold the non-binding vote on executive compensation, and "FOR" the ratification of our auditor.

Proposal No. 1 – Election of Directors.

A nominee will be elected if the votes cast for the nominee’s election exceed the votes cast against such nominee’s election. There is no cumulative voting in the election of directors.

Proposal No. 2 – Advisory (Non-Binding) Vote on Executive Compensation.

The annual advisory vote will be approved if a majority in voting power of the shares present in person or represented by proxy and entitled to vote cast their votes for the proposal. Because the vote is advisory, neither the Company nor the Board of Directors will be bound to take action based upon the outcome. However, the Compensation



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	2



Table of Contents

VOTING RIGHTS • QUORUM AND SUMMARY OF PROPOSALS

Committee and Board of Directors will consider the outcome of the vote when considering future executive compensation arrangements.

Proposal No. 3 – Advisory (Non-Binding) Vote on Frequency of Executive Compensation Votes.

The option of one year, two years or three years that receives the greatest number of votes by shares present in person or represented by proxy and entitled to vote will be deemed the frequency for the advisory vote on the compensation of our named executive officers that has been selected by stockholders. Because the vote is advisory, neither the Company nor the Board of Directors will be bound to take action based upon the outcome. However, the Compensation Committee and Board of Directors will consider the outcome of the vote when considering the frequency of future advisory approval votes regarding executive compensation.

Proposal No. 4 – Ratification of Auditor.

The proposal to ratify the appointment of RSM US LLP as the Company’s independent auditor will be approved if a majority in voting power of the shares present in person or represented by proxy and entitled to vote cast their votes for the proposal. If the appointment is not approved by the stockholders, the adverse vote will be considered a direction to the Audit Committee to consider other auditors for next year. However, because of the difficulty in making any substitution of auditors so long after the beginning of the current year, the appointment in 2018 will stand, unless the Audit Committee finds other good reason for making a change.

The management and Board of Directors of the Company know of no other matters to be brought before the meeting. If other matters are properly presented to the stockholders for action at the meeting or any adjournments or postponements thereof, it is the intention of the proxy holders named in the proxy to vote in their discretion on all matters on which the shares of common stock represented by such proxy are entitled to vote.

Shares in the Company 401(k) Plan

If you hold shares in the Western Alliance Bancorporation 401(k) Plan (the “401(k) Plan”), you may instruct the plan trustee on how to vote your shares in the 401(k) Plan by mail, by telephone or over the internet as described above. You may vote or provide instructions with respect to all of the shares of our common stock allocated to your account on the Record Date.

In addition, your vote or instructions will also apply pro rata, along with the votes or instructions of other participants in the 401(k) Plan who return voting instructions to the trustee, to all shares held in the 401(k) Plan for which voting directions are not received. These undirected shares may include shares credited to the accounts of participants who do not return their voting instructions and shares held in the 401(k) Plan that were not credited to individual participants’ accounts as of the Record Date. The trustee will automatically apply your voting preference to the undirected shares proportionately with all other participants who provide voting directions.

Corporate Governance

The Board of Directors is responsible for ensuring effective governance over the Company’s affairs. The Company has adopted Corporate Governance Guidelines and a Code of Business Conduct and Ethics. These documents are available in the Governance Documents section of the Investor Relations page of the Company’s website at www.westernalliancebancorporation.com or, for print copies, by writing to the Company at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, Attention: Corporate Secretary.

Board Leadership Structure

In accordance with the Company’s Bylaws, as amended (“Bylaws”), the Chairman of the Board of Directors (the “Chairman”) is a discretionary position whose sole stated duty is to preside at meetings of the Board of Directors and meetings of stockholders, as well as to perform such other duties as assigned to him by the Board of Directors. The Chief Executive Officer (“CEO”) is required to be a member of the Board of Directors, subject to the direction of the Board of Directors, and has general supervision, direction and control of the business and officers of the Company. The positions of Chairman and CEO may be held by the same person or may be held by two people. The Board of Directors does not have a definitive policy on whether the role of the Chairman and the CEO should be separate.

The Company has a Lead Independent Director, who is selected by the non-management directors, because the Board of Directors believes the position can contribute to improved corporate performance in the following ways: (1) supporting effective communication and building a productive relationship between the CEO and other members



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	3



Table of Contents

CORPORATE GOVERNANCE • BOARD LEADERSHIP STRUCTURE

of executive management and the Board of Directors; (2) leading the process for improving performance of the Board of Directors; and (3) assisting in a crisis. Bruce Beach has served as the Company’s Lead Independent Director since 2010. In addition to the duties of all directors, the specific responsibilities of the Company’s Lead Independent Director are as follows:



Lead Independent Director Responsibilities
Ÿ	Assist the Chairman/CEO with setting the Board agenda and schedules;	Ÿ	Lead the Board process to ensure focus on strategic issues rather than minutiae;
Ÿ	Preside at meetings in the absence of the Chairman;	Ÿ	Facilitate outside director action in a crisis;
Ÿ	Assist new Board members and provide counsel needed to enable them to become active and productive contributors;	Ÿ	Lead the Board to achieve consensus in its deliberations while reaching timely decisions;
Ÿ	Call for meetings of the independent and/or non-management directors as necessary, set the agenda and preside at such meetings;	Ÿ	Stay informed about Company activities, strategies, performance and provide counsel and feedback to the CEO;
Ÿ	Work with the Governance Committee regarding committee assignments, succession planning and Board candidates;	Ÿ	Work with the Governance Committee to lead the Board and individual directors through an annual evaluation process; and
Ÿ	Lead the Board in evaluating the CEO;	Ÿ	If requested, communicate directly with stockholders.
Ÿ	Provide feedback to the CEO and management team on issues of interest or concern to the Directors, including ensuring the Board has the information it has requested;

Effective April 1, 2018, Robert Sarver stepped down from his position as CEO of the Company and was appointed to the newly created position of Executive Chairman. The Nominating and Corporate Governance Committee (the “Governance Committee”) determined that separating the roles of CEO and Chairman at this time is the best approach to guiding the Company through a successful CEO transition. Mr. Sarver will continue to preside over board meetings in his new role of Executive Chairman, and the Company will continue to utilize a Lead Independent Director due to Mr. Sarver's ongoing executive duties. The Governance Committee believes this leadership structure is the most appropriate for the Company and its stockholders. The Governance Committee based its determination on a number of reasons, the most significant of which include the following:

•

In executing the Company's CEO succession plan, the Governance Committee determined that continuity of leadership at the Board level during the transition in Company management would provide maximum stability to the Company and its stockholders. Mr. Sarver has had, and will continue to have, a substantial role in the Company's success. As the Company's new CEO, Kenneth Vecchione, takes on Mr. Sarver's previous responsibilities as CEO, Mr. Vecchione and the Company will benefit from Mr. Sarver's experience and guidance; and

•

The structure of our Board of Directors provides strong oversight by independent directors. Our Lead Independent Director’s responsibilities include leading independent and non-management sessions of the Board of Directors during which our directors meet without management. These sessions allow the Board of Directors to review key decisions and discuss matters in a manner that is independent of the CEO and Executive Chairman and, where necessary, critical of the CEO, the Executive Chairman, and senior management. In addition, each of the Board of Directors’ standing committees is chaired by an independent director.

Director Selection Process

One of the primary responsibilities of the Governance Committee is to assist the Board of Directors in identifying, and reviewing the qualifications of, prospective directors of the Company. The Board of Directors and the Governance Committee periodically review the appropriate size and composition of the Board of Directors. In considering candidates for the Board of Directors, the Governance Committee considers the entirety of each candidate’s credentials and does not have any specific minimum qualifications that must be met by a Governance Committee-recommended nominee.



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	4



Table of Contents

CORPORATE GOVERNANCE • DIRECTOR SELECTION PROCESS



The Governance Committee is guided by the following basic selection criteria for all nominees:	Ÿ	The director’s/potential director’s character and integrity, experience and understanding of strategy and policy-setting, reputation for working constructively with others and sufficient time to devote to matters of the Board of Directors;
	Ÿ	The director’s/potential director’s educational, business, non-profit or professional acumen and experience;
	Ÿ	Whether the director/potential director assists in achieving a mix of directors that represents a diversity of background, perspective and experience, including with respect to age, gender, race, place of residence and specialized experience;
	Ÿ	Whether the director/potential director meets the independence requirements of the SEC and listing standards of the NYSE;
	Ÿ	Whether the director/potential director has the financial acumen or other professional, educational or business experience relevant to an understanding of the Company’s business, such as experience in a regulated industry or a publicly held company;
	Ÿ	Whether the director/potential director would be considered a “financial expert” or “financially literate” as defined in the listing standards of the NYSE or applicable law;
	Ÿ	Whether the director/potential director, by virtue of particular technical expertise, experience or specialized skill relevant to the Company’s current or future business, will add specific value as a director; and
	Ÿ	Whether the director/potential director possesses a willingness to challenge and stimulate management and the ability to work as part of a team in highly regulated environment.

The Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. In 2016, the Governance Committee adopted a Director’s Skills & Experience Matrix outlining what it believes to be the key areas of expertise needed from Board members and identifying how each member contributes to the Board’s overall skillset. This practice allows the Governance Committee to assess opportunities to improve the Board’s diversity based on each member’s personal factors and professional characteristics. Using this methodology, the Governance Committee is dedicated to enhancing the skills and talent of its Board by identifying specific areas for improvement necessary, thereby delineating the pool of persons considered for new Board positions.

In 2017, the Board decreased its size from sixteen directors to fourteen and, in so doing, did not nominate two long standing directors to an additional term. This reduction in size positioned the Board to allow the recruitment of new directors as the need arises. The Governance Committee identified as one of its top priorities the need to recruit a new director who not only provides a valuable skillset to the Board, but also will contribute to its gender diversity. The Governance Committee is pursuing a methodical approach to identify the right director candidate to recommend to the full Board. It expects to have the process completed with a recommendation to the full Board in the second half of 2018. In addition to recruiting this new director, the Governance Committee will continue to evaluate the size and composition of our Board on an ongoing bases.

The Governance Committee will consider nominees for directors recommended by stockholders. A stockholder wishing to recommend a director candidate for consideration by the Committee should send such recommendation to the Company’s Corporate Secretary at the address shown on the cover page of this proxy statement, who will then forward it to the Governance Committee. Any such recommendation should include the following minimum information for each director nominee: full name, address and telephone number, age, a description of the candidate’s qualifications for service on the Board of Directors (such as principal occupation and directorships on publicly-held companies during the past five years), the candidate’s written consent to be considered for nomination and to serve if nominated and elected, and the number of shares of Company common stock owned, if any. A stockholder who wishes to nominate an individual as a director candidate at the annual meeting of stockholders, rather than recommend the individual to the Governance Committee as a nominee, must comply with certain advance notice requirements. See “Stockholder Proposals for the 2019 Annual Meeting” on page 53 for more information on these procedures.

Table of Contents

CORPORATE GOVERNANCE • DIRECTOR SELECTION PROCESS

If the Governance Committee receives a director nomination from a stockholder or group of stockholders who (individually or in the aggregate) beneficially own greater than 5% of the Company’s outstanding voting stock for at least one year as of the date of such recommendation, the Company, as required by applicable securities law, will identify the candidate and stockholder or group of stockholders recommending the candidate and will disclose in its proxy statement whether the Governance Committee chose to nominate the candidate, as well as certain other information.

In addition to potential director nominees submitted by stockholders, the Governance Committee considers candidates submitted by directors, as well as self-nominations by directors and, from time to time, it may consider candidates submitted by a third-party search firm hired for the purpose of identifying director candidates. The Governance Committee conducts an independent due diligence process to review potential director candidates and their individual qualifications, and all such candidates, including those submitted by stockholders, will be similarly evaluated by the Governance Committee using the Board of Directors membership criteria described above.

All of the nominees standing for election to the Company’s Board of Directors at this year’s Annual Meeting are current directors. The Governance Committee and the Board of Directors believe that all the nominees satisfy the above described director standards. Accordingly, all of such nominees were approved for re-election by the Board of Directors, based in part on the recommendation of the Governance Committee. With respect to this year’s Annual Meeting, no nominations for directors were received from stockholders.

Board Composition

The Company’s Bylaws provide that the Board of Directors will consist of not less than eight or more than seventeen directors. The Board of Directors may, from time to time, fix the number of directors within these limits. Currently, the Board of Directors has fixed the number of directors at fourteen. At the Annual Meeting, the fourteen directors described in the “Information as to Director Nominees” section will be elected to serve for one-year terms.

At each annual meeting of stockholders, the successors to directors whose terms will then expire will be elected to serve from the time of election and qualification until the annual stockholders’ meeting following election. The number of directors may be changed only by resolution of the Board of Directors.

Information regarding each of the Company’s directors is set forth below. All ages are provided as of December 31, 2017.

Information as to Director Nominees

The terms of the following directors will expire at this year’s Annual Meeting. The Board of Directors has nominated the individuals listed below, all of whom are current directors of the Company, to be elected as directors at the Annual Meeting. See “Items of Business To Be Acted On At The Meeting – Proposal No. 1 Election of Directors” on page 49. Each of the nominated directors currently serves as a director of the Company's wholly owned bank subsidiary, Western Alliance Bank, and, in connection with his or her re-election to the Company's Board of Directors, will also be nominated and re-elected to the board of Western Alliance Bank.

CORPORATE GOVERNANCE • DIRECTOR INDEPENDENCE

Director Independence

The Company’s common stock is traded on the NYSE. The NYSE’s rules require that a majority of directors of NYSE-listed companies be “independent.” For a director to be “independent” under the NYSE’s rules, the Board of Directors must affirmatively determine that the director has no material relationship with the Company, including its subsidiaries, either directly or as a partner, stockholder, or officer of an organization that has a relationship with the Company, and a director must satisfy all categorical standards relating to independence, as set forth in Section 303A of the NYSE Listed Company Manual.

Of the 14 persons nominated for election to the Board of Directors, 11 have been determined by the Board of Directors to be independent under NYSE standards. The Board of Directors based these determinations primarily on the recommendations of the Governance Committee, which performed a detailed review of the Company’s internal records and the responses of the directors to questions regarding employment and compensation history, affiliations and family and other relationships, and on discussions with such directors. As part of its review, the Governance Committee considered, among other things, the nature and extent of each director’s business relationships and transactions with the Company, its subsidiaries, and its executive officers and their affiliated business entities, including personal investment activities, professional services, involvement in charitable or non-profit organizations, and those relationships and transactions described in each of the "Certain Transactions with Related Persons" and the "Certain Business Relationships" sections herein, located on page 44.

Based on these factors, the Board of Directors determined that Messrs. Sarver and Vecchione are not independent because both serve as executive officers of the Company. Likewise, the Board of Directors determined that Mr. Hilton is not independent. In evaluating Mr. Hilton’s independence, the Board of Directors considered the fact that he is Chairman and CEO of Meritage Homes Corporation (“Meritage”), and Mr. Sarver is a member of the board of directors of Meritage. The board of directors of Meritage considers Mr. Sarver to be a non-independent director. In addition, the Board of Directors also considered the fact that Mr. Sarver is the Managing Partner of the entity which owns the Phoenix Suns NBA basketball team, and Mr. Hilton is a limited partner in the Phoenix Suns ownership group. Further, Mr. Hilton is an investor in multiple commercial real estate ventures in which Mr. Sarver also has a direct or indirect interest, and Mr. Sarver serves as trustee of certain trusts that Mr. Hilton has established for the benefit of his children. Accordingly, based on the totality of these circumstances, and notwithstanding that Mr. Hilton satisfies all of the NYSE’s categorical standards for independence, the Company’s Board of Directors concluded it is in the best interest of the Company’s stockholders that Mr. Hilton not be deemed an independent director.

Meetings of the Board of Directors

The Board of Directors held eight meetings in 2017. Each current director attended at least 75% of the meetings of the Board of Directors and meetings of committees on which he or she served in 2017. The Company invites and encourages all of its directors to attend the Company’s annual meetings of stockholders, and all of the directors attended the 2017 annual meeting of stockholders.

Executive sessions of non-management directors (consisting of all directors other than Messrs. Sarver and Vecchione) and independent directors’ sessions (consisting of all directors other than Messrs. Sarver, Vecchione, and Hilton) are regularly scheduled and held during the Company’s regular quarterly Board of Directors meetings.

Board Role in Risk Oversight

Under the Company’s governance structure and applicable law, the Board of Directors is ultimately responsible for overseeing the Company’s risk management processes. The Company has adopted a three lines of defense risk management model, and the Board has distributed certain oversight responsibilities to its committees in keeping with the Board's obligation to oversee and monitor the three lines of defense.

The first line of defense is primarily evaluated by the full Board, and the Company's executive officers make reports to the full Board of Directors regarding the risks within their areas of responsibility. Additionally, certain first line areas requiring special attention are delegated to Board Committees for in depth review.

The Board has assigned primary oversight for the second line of defense (including the compliance and risk management functions) to the Directors Risk Committee (the "Risk Committee"), except where responsibility for compliance with particular laws and regulations have been specifically assigned to a different Board Committee (e.g., compliance with financial reporting regulations, which is overseen by the Audit Committee). The Risk Committee satisfies itself that sound policies, procedures and practices are implemented for the management of key risks under the Company’s Enterprise Risk Management framework, including credit, concentration, operational, market,



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	11



Table of Contents

CORPORATE GOVERNANCE • BOARD ROLE IN RISK OVERSIGHT

regulatory, information technology, reputational, strategic, business, modeling, legal and external/environmental risks. The Risk Committee reports regularly to the Board of Directors regarding material matters discussed at meetings of the Risk Committee, as well as the current status of risk and action items. The Risk Committee assists the Board of Directors and its other committees with their risk-related activities, and acts as a resource to management, including the Company’s Enterprise Risk Management Committee (“ERMC”).

Primary oversight of the third line of defense is assigned to the Audit Committee, which is tasked with oversight of the Company’s audit function and financial reporting. The Audit Committee oversees the evaluation of the adequacy of the Company's internal controls and its major financial risk exposures and the steps management has taken to monitor and control such exposures. The Audit Committee, along with all of the Board Committees, regularly reports to the full Board on their risk management activities.

The Company has also dedicated substantial management resources to its internal risk management processes. The Company’s Chief Risk Officer (“CRO”) reports to both the Risk Committee and the Company’s Chief Operating Officer. The Company’s CRO oversees periodic comprehensive company-wide risk assessments and manages the Company’s enterprise risk management program. The CRO chairs the ERMC, which is composed of many of the Company’s senior executives and subject matter experts. Under its charter, the ERMC meets on a regular basis throughout the year and is responsible for: (1) identifying and prioritizing business and financial risks, consistent with our Risk Appetite Statement; (2) oversight of business process risk; (3) ensuring that any identified risk control gaps are addressed; and (4) continually improving the Company’s risk management infrastructure. The CRO provides regular reports on ERMC activities to the Risk Committee and the full Board of Directors.

Finally, because the Board of Directors believes that skilled and well-informed directors are vital to effectively fulfilling the governance responsibilities of the Board of Directors, including oversight of the Company’s risk management processes, it has adopted and implemented a formal Director Training and Education Program.

Non-Employee Director Stock Ownership Guidelines

The Board of Directors adopted Stock Ownership Guidelines for directors and executive officers because it believes that it is important to the Company’s future success that senior management and directors own and hold a minimum number of shares of common stock of the Company in order to further align their interests and actions with the interests of the Company’s stockholders. The Stock Ownership Guidelines require non-employee directors to own a minimum number of shares of the Company’s common stock, which is the number of shares having a value at least equal to five times such director’s annual cash compensation as reported in the Company’s most recent proxy statement. The Stock Ownership Guidelines provide for a transition period of five years during which new directors must achieve full compliance with these requirements. The Stock Ownership Guidelines are administered and enforced by the Governance Committee of the Board of Directors, and compliance is monitored and reported to the Committee by the Company’s General Counsel. Each director is in full compliance with these requirements. Stock Ownership Guidelines for the Company’s executive officers can be found on page 33.

The Company understands that hedging and significant amounts of pledging of Company stock by directors and executive officers may skew the alignment of the interests between Company insiders and Company stockholders. Therefore, the Stock Ownership Guidelines specifically prohibit any hedging of Company stock held by directors and executive officers, exclude pledged shares from required ownership levels, and establish both individual and collective maximums on Company shares that may be placed in a margin account or otherwise pledged.

Communication with the Board of Directors and its Committees

Any stockholder or other interested person may communicate with the Board of Directors, a specified director (including the Lead Independent Director), the non-management directors as a group, or a committee of the Board of Directors by directing correspondence to their attention, in care of the Corporate Secretary, Western Alliance Bancorporation, One E. Washington Street, Suite 1400, Phoenix, Arizona 85004. Anyone who wishes to communicate with a specific director, the non-management directors only or a specific committee should send instructions asking that the material be forwarded to the appropriate director, group of directors or committee chairman. All communications so received from stockholders or other interested parties will be forwarded to the director or directors designated.

Audit Committee Report

The Board of Directors of Western Alliance Bancorporation approved the charter of the Company’s Audit Committee on April 27, 2005, and the charter was most recently amended on January 30, 2018. The charter states that the primary purpose of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing: (i) the Company’s financial reports and other financial information provided by the Company to governmental bodies (e.g., federal and state banking regulators, the SEC, and the Internal Revenue Service) or the public; (ii) the Company’s systems of internal controls regarding finance, accounting, regulatory compliance and ethics that management and the Board of Directors have established; (iii) the Company’s internal audit function; and (iv) the Company’s auditing, accounting and financial reporting processes. The Audit Committee periodically reports on these and other pertinent matters that come before it to the full Board of Directors.

The following four directors are currently members of the Audit Committee: Messrs. Patriarca (Chairman), Latta, Beach, and Dr. Sohn. The Board of Directors has determined that each member of the Audit Committee satisfies the requirements of the applicable laws and regulations relative to the independence of directors and Audit Committee members, including, without limitation, the requirements of the SEC and the listing standards of the NYSE. The Board of Directors has further determined, in its business judgment, that each member of the Audit Committee is “financially literate” under NYSE listing standards and that Mr. Beach qualifies as an “audit committee financial expert” as defined by the SEC. During 2017, the Audit Committee met ten times.

While the Audit Committee has the duties and responsibilities set forth in its charter, it is not the responsibility of the Audit Committee to plan or conduct audits, to implement internal controls, or to determine or certify that the Company’s financial statements are complete and accurate or are in compliance with generally accepted accounting principles in the United States of America (“GAAP”). Furthermore, it is not the duty of the Audit Committee to assure compliance with applicable laws, rules, and regulations. These are the duties and responsibilities of management, the Company’s independent registered public accounting firm, and others as described more fully below.



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	18

CORPORATE GOVERNANCE • AUDIT COMMITTEE REPORT

Management is responsible for the Company’s financial reporting process, which includes the preparation of the Company’s financial statements in conformity with GAAP, and the design and operating effectiveness of a system of internal controls and procedures to provide compliance with accounting standards and applicable laws, rules, and regulations. Management is also responsible for bringing appropriate matters to the attention of the Audit Committee and for keeping the Audit Committee informed of matters that management believes require attention, guidance, resolution, or other actions. RSM US LLP, the Company’s independent registered public accounting firm, is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) and for expressing an opinion on the conformity of the Company’s consolidated financial statements with GAAP.

During the year, the Audit Committee discussed with RSM US LLP and the Company’s internal auditors, with and without management present, the overall scope and plans for their respective audits, the results of their examinations, and their evaluations of the effectiveness of the Company’s internal controls and of the overall quality of the Company’s financial reporting.

The Audit Committee reviewed and discussed the audited consolidated financial statements of the Company for the year ended December 31, 2017 with RSM US LLP, the Company’s independent registered public accounting firm, and management. In addition, the Audit Committee discussed with RSM US LLP those matters required to be discussed under generally accepted auditing standards, including Statement on Auditing Standards No. 1301 (Communication with Audit Committees) as currently in effect.

RSM US LLP has provided to the Audit Committee the written disclosures and the letter required by the PCAOB’s Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, as currently in effect, and the Committee discussed with RSM US LLP any relationships that may impact on the firm’s objectivity and independence and satisfied itself as to the auditors’ independence. In addition, the Audit Committee reviewed and approved the fees paid to RSM US LLP for audit and non-audit related services.

Based on the reviews and discussion referred to above, the Audit Committee approved the inclusion of the Company’s audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 for filing with the SEC.

Compensation Committee Matters

The Committee’s Processes and Procedures

The Compensation Committee’s charter is reviewed no less than annually to ensure that the Compensation Committee is fulfilling its duties in aligning the Company’s executive compensation program with the creation of stockholder value. The Board of Directors adopted the Committee’s charter on April 27, 2005, and most recently approved the charter on January 30, 2018.

The Compensation Committee’s charter provides the Compensation Committee with the sole authority and discretion to engage and terminate outside advisors to study and make recommendations regarding director or executive compensation matters, and has the sole authority to approve their fees and other retention terms. In 2017, the Compensation Committee retained Willis Towers Watson (the “Consultant”) as its outside independent compensation consultant to advise it on director and executive compensation matters. In this capacity, the Consultant reported directly to the Committee and provided data, analysis and guidance to assist the Committee in ensuring that the Company’s executive compensation programs and director compensation programs are appropriate, reasonable, and consistent with the Committee’s compensation objectives.

The Compensation Committee works directly with the Consultant to determine the scope of the work needed to assist the Committee in its decision-making processes. The Consultant attended Compensation Committee meetings



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	19



Table of Contents

CORPORATE GOVERNANCE • COMPENSATION COMMITTEE MATTERS

to present and discuss market data and program design alternatives, and to provide advice and counsel regarding decisions facing the Compensation Committee. The Compensation Committee also meets regularly with the Consultant on an informal basis and without executive management. The Consultant provided no services to the Company other than services that were requested by the Committee; and the independence assessment that the Compensation Committee conducted confirmed that no conflicts of interest existed with respect to the Consultant’s work.

In 2017, the Committee directed the Consultant to provide executive compensation benchmarking and market analysis to inform the Committee’s compensation decisions and recommendations. The Consultant provided an analysis of the Company’s compensation program in comparison to proxy data from the Company’s Peer Group (as defined on page 26) and financial services industry published survey data. The Committee also directed the Consultant to analyze the pay practices of other companies moving through a CEO succession process, and compensation arrangements for executive chairmen in other publicly held companies. There were no actions taken directly pursuant to these studies, but Committee used the overall information provided by the Consultant to help inform their executive compensation decisions. The Consultant also provided the Committee a Peer Group review, and the Committee's decisions with respect to that review are discussed on page 26.

The Compensation Committee Chairman works with management to set individual meeting agenda for the Compensation Committee following an overall annual calendar of regular activities. The CEO, the Company’s Chief Administrative Officer and Deputy General Counsel are the primary representatives of management who interact with the Compensation Committee, and serve as liaisons between the Compensation Committee and Company management. These officers regularly attend Compensation Committee meetings, and provide input and recommendations on compensation matters, as discussed more fully in the “Compensation Discussion and Analysis” below. They work with other senior executives to develop and recommend compensation strategies and practices to the Compensation Committee for its review and approval, including the performance goals and weighting factors used in the Company’s performance-based plans and base salary adjustments for specific officers. The Chief Administrative Officer also works directly with the Consultant on a variety of Compensation Committee matters and provides administrative support and assistance to the Compensation Committee.

Compensation Committee Interlocks and Insider Participation

Each member of the Compensation Committee is an independent director under standards of the NYSE, is an outside director for purposes of Section 162(m) under the Code, and is a non-employee director under Section 16 of the Exchange Act. No member of the Compensation Committee is a current or former officer or employee of the Company or any subsidiary.

At December 31, 2017, the Company’s executive officers, directors and principal stockholders (and their related interests) were indebted to the Bank in the aggregate amount of approximately $5.9 million. This amount was approximately 0.04% of total gross loans outstanding as of such date. All of the foregoing loans (i) were made in compliance with Regulation O promulgated by the Federal Reserve Board; (ii) were made in the ordinary course of business; (iii) were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the Company; and (iv) did not involve more than the normal risk of collectability or present other unfavorable features.

As a group, the Company’s directors and executive officers hold 7.95% of the outstanding common stock of the Company. Additional detail regarding the ownership of each director and executive officer can be found in the beneficial ownership table beginning on page 47.

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

In 2017, the Company strengthened its executive management team and focused its efforts on managing a successful CEO transition in 2018. The Company's overall compensation structure did not change, and continues to strongly link executive pay to performance that benefits shareholders. A significant portion of total direct compensation depends on the Company’s achieving challenging performance targets established in its annual bonus plan and equity awards. The Company did make specific executive compensation decisions outside of its standard annual cycle in order to attract and retain Mr. Vecchione and Mr. Haught to its leadership team. In order to attract these persons and to maintain the competitiveness of the executive officers’ total compensation packages, the Company made the following noteworthy decisions in 2017:


•	Increased Mr. Sarver's salary by 20% due to his proven track record of success and the Compensation Committee's desire to reward his outstanding performance;


•	Increased Mr. Gibbon’s salary by 20% based on another record year of Company performance and in recognition of his value to the Company;


•	Set annual bonus targets in line with prior years and with a balanced approach to measuring the Company's success;


•	Entered into employment agreements with each of Messrs. Vecchione and Haught, providing equity grants and bonuses commensurate with their responsibilities, skills, and individualized circumstances; and


•	Lowered the total number of shares granted to executives due to the increasing value of each share.

Compensation Design

The Compensation Committee, on behalf of the Board of Directors, performs the responsibilities relating to the compensation of the Company’s directors and executive officers. The Committee seeks to establish total compensation for the Company's executive officers that is fair, reasonable, competitive in the industry, and aligned with value creation for shareholders. The Company expects that its compensation program will enable it to attract and retain the high quality executive officers required to successfully manage and grow the Company. The Committee, the Board of Directors and management work together to ensure that compensation practices fairly reward executives for leading the Company through uncertain times, achieving predetermined performance criteria and implementing sound risk management practices. The Committee also takes action to ensure compensation is appropriately limited when necessary to serve the best interests of the Company or as required by regulatory constraints.

2017 Advisory Vote on Executive Compensation

The Company provides stockholders with the ability to cast an annual advisory vote on the compensation of its executives. Over 98% of voting stockholders voted in favor of the 2016 compensation of the named executive officers as disclosed in the 2017 proxy statement. The Compensation Committee considered the results of the 2017 say-on-pay vote in determining 2018 compensation, but did not make pay changes as a direct result of the advisory vote or feedback from shareholders. The Committee will continue to consider the outcome of the Company’s say-on-pay votes when making future compensation decisions.

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

Benchmarking of Compensation

The 2017 Peer Group is comprised of 21 banking organizations the Company used to analyze the NEOs’ compensation as compared to market practices. This group of banking companies was compiled by considering all banks with total assets within a range of approximately 0.7x to 2.0x the Company’s total assets, and with a commercial banking focus. For compensation purposes, the Committee uses a subset of the larger group of companies that the Company uses for purposes of comparing financial and stock performance.

The Company believed the Peer Group to be representative of those companies that are regional leaders in their markets and with which the Company competes for executive talent. The members of the 2017 Peer Group were:



•	Bank of the Ozarks	•	Old National Bancorp

•	BankUnited, Inc.	•	PacWest Bancorp

•	Boston Private Financial Holdings, Inc.	•	Pinnacle Financial Partners, Inc.

•	Cathay General Bancorp	•	Signature Bank

•	Columbia Banking System, Inc.	•	Texas Capital Bancshares, Inc.

•	CVB Financial Corp.	•	Trustmark Corporation

•	East West Bancorp	•	UMB Financial Corp.

•	First Financial Bancorp	•	Umpqua Holdings Corp.

•	IBERIABANK Corporation	•	Valley National Bancorp

•	Investors Bancorp Inc.	•	Washington Federal, Inc.

•	MB Financial

The Compensation Committee reviewed the Company's Peer Group with the Consultant in 2017 to ensure that the Peer Group continues to be appropriate in light of the Company's continued growth. After discussing potential alterations to the current Peer Group with the Consultant, the Compensation Committee approved modifying the Peer Group for 2018 by removing Boston Private Financial Holdings, Inc. and First Financial Bancorp, and including Bank of Hawaii Corporation and Bancorp South.

Peer Group information is an important part of the analysis the Consultant provides to the Committee so that the Company can maintain executive compensation strategies that are competitive and ensure that compensation is adequate to retain and motivate key executives.

The Compensation Committee believes that its executive officers should receive total compensation that is competitive with comparable employers in the financial services industry and closely aligned with both the Company’s short-term and long-term performance, while at the same time complying with applicable regulatory requirements. The Compensation Committee seeks to provide compensation targeted to reflect the value and performance of executives in the market. Actual total direct compensation for executives may vary as necessary based on recommendations of the CEO, direction from the Board of Directors, performance of the Company or any subsidiary or division, individual performance, the experience level of individual executives, internal equity considerations, acquisition-related commitments, external market factors, and similar considerations.

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

Elements of Executive Compensation

The principal elements of the Company’s compensation program for NEOs during 2017 consisted of:


•	Base Salary


•	Annual Bonus


•	Long-Term Equity: Performance-Based Stock Units and Restricted Stock Awards


•	Standard Benefits and Limited Perquisites

The Compensation Committee reviews and approves final pay packages for all executive officers except for the CEO and Executive Chairman, whose compensation is recommended by the Compensation Committee and approved by the Board of Directors. In evaluating and approving the compensation of executive officers, other than the CEO and Executive Chairman, the Compensation Committee receives input from Messrs. Sarver and Vecchione and considers its own assessment of their performance as it has frequent exposure to these officers.

Annual Base Salary

The Company views a competitive annual base salary as a crucial component to attract and retain executive talent. In 2017, the Board of Directors determined the base salary for Messrs. Sarver and Vecchione after reviewing the Compensation Committee’s analysis. The Compensation Committee determines the base salary for other executive officers (including the NEOs) after considering the Consultant’s analysis, recommendations from Messrs. Sarver and Vecchione, and making its own assessments regarding individual performance, experience and other factors.

2017 Salary Determination

In January 2017, the Compensation Committee reviewed the Company’s superior performance in 2016, and recognized that the Mr. Sarver has consistently delivered outstanding value to shareholders for more than five consecutive years. After keeping base salaries relatively stable in 2014-2015, the Committee decided strong performance of the Company deserved more substantial increases for 2016 performance. In light of his proven track record of success and in the spirit of rewarding outstanding performance, the Committee recommended, and the Board of Directors approved, a 20% increase to Mr. Sarver’s base salary, raising it to $1,200,000. The Compensation Committee agreed with Mr. Sarver's recommendation of a similar increase for Mr. Gibbons, and increased Mr. Gibbons’ base salary by 20% to $600,000. Mr. Myers’ base salary received a $15,000 increase as established by his Employment Agreement with Western Alliance Bank, bringing his base salary to $465,000 for 2017.

Additionally, in 2017 the Company hired Mr. Vecchione as part of its CEO succession planning process. Due to the long term plan for Mr. Vecchione to assume the responsibilities of CEO, the Company entered into an Offer Letter with Mr. Vecchione that included executive compensation terms consistent with those of an incoming chief executive officer. The Compensation Committee recommended, and the Board approved, an initial base salary of $1,000,000 for Mr. Vecchione, with increases established pursuant to the terms of the Offer Letter. For more information regarding Mr. Vecchione's Offer Letter please see the "Termination Outside of a Change in Control" section on page 40 and the "Employment Agreements" section on page 43.

The Company also hired Mr. Haught to serve as Chief Operating Officer in 2017, primarily overseeing the Company's Risk Management and Information Technology/Operations functions. Due to the logistics and expense of relocating to Phoenix, Arizona, the Company agreed to split Mr. Haught's 2017 cash compensation into two components, consisting of a pro-rata base salary of $200,000 and a one-time signing bonus of $250,000.

2018 Salary Determination

In January 2018, the Compensation Committee reviewed Mr. Sarver's 2017 performance and his transition plan for the new Executive Chairman position, which went into effect on April 1, 2018. The Consultant also provided the Compensation Committee with information about similar situations in the labor market and peer approaches. The Committee determined that Mr. Sarver will continue to be highly engaged in guiding the success of the Company, particularly on strategic matters. In recognition of Mr. Sarver's outstanding performance in 2017, as well as his ongoing commitment to the Company's success, the Committee determined a base salary of $900,000 was appropriate for Mr. Sarver's Executive Chairman duties. The Committee believes that this level of compensation reflects the value and experience Mr. Sarver will continue to provide to the Company in his new more limited role.

In connection with Mr. Sarver's transition to Executive Chairman, the Company promoted Mr. Vecchione to the role of CEO. As provided for in Mr. Vecchione's Offer Letter, Mr. Vecchione's base salary was increased by 10%



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	27



Table of Contents

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

in 2018 to $1,100,000. The increases in Mr. Vecchione's salary, as provided under the Offer Letter, were included with the understanding that Mr. Vecchione responsibilities with the Company would significantly increase as part of his transition into the role of CEO. With respect to Mr. Gibbons, the Compensation Committee decided upon a base salary increase of 12.5%, to $675,000, based on the recommendation of Messrs. Sarver and Vecchione, and in recognition of Mr. Gibbons' continued contributions to the Company's success. Similarly, the Compensation Committee approved a base salary of $625,000 for Mr. Haught in recognition of the duties and responsibilities inherent in his role as President and Chief Operating Officer. Mr. Myers received a base salary increase of $15,000 increase, as established by his Employment Agreement, bringing his base salary to $480,000 for 2018.

Annual Bonus Plan

The Western Alliance Bancorporation Annual Bonus Plan (“Annual Bonus Plan”) is designed to create a pay-for-performance environment and is intended to motivate and retain qualified employees by providing the potential for an annual cash or equity award based on the Company’s achievement of pre-determined performance criteria. The Annual Bonus Plan serves the Company’s compensation objective of rewarding executives for the attainment of short- and long-term financial performance goals.

The Annual Bonus Plan is designed to provide market competitive payouts for the achievement of threshold, target and maximum performance goals. Establishment of the performance levels (threshold, target, and maximum) takes into account all factors that management and the Compensation Committee deem relevant, including market conditions and an assessment of a level of growth that is both aggressive and achievable for each performance criterion. Additionally, the Annual Bonus Plan restricts excessive risk-taking by not providing uncapped payouts and putting a ceiling on potential bonus payments.

2017 Annual Bonus Determination

The Compensation Committee continues to believe that EPS should be the most significant component of the performance metrics used to determine executive officers' compensation, including annual bonuses and long term incentive awards. The Company has prioritized EPS for a number of years as the best measure available to evaluate the Company's success and ability to deliver value to shareholders, with outstanding results. The focus on EPS has resulted in TSR returns at, or near, the top of the Peer Group over a 1-year, 3-year and 5-year period. EPS captures elements of corporate performance that are beyond those of the individual operating business lines, such as corporate funding policies and the management and allocation of capital. EPS also addresses the importance of stable asset quality through the provision which puts an emphasis on both near and longer term earnings. Additionally, EPS targets are aligned with the Company's annual and long term financial plans, which the Board and management have assessed for achievability. Accordingly, the EPS targets provide incentives to take appropriate amounts of risk to achieve those goals. However, the Company revisits the annual bonus plan performance factors on a yearly basis. Although EPS is the Company’s preferred performance metric for the annual bonus and performance-based equity awards, the weight of EPS in the annual bonus plan has fluctuated over time to allow for emphasis on other high priority measurements, such as asset quality metrics and deposit growth.

The Company’s 2017 target goals and actual performance for each bonus component is provided below. The goals were above industry averages, and overall performance was at the top of the Peer Group.

After consultation with management, the Committee applied some downward discretion to this performance factor to emphasize its importance and the Company's capacity for continued progress in the area.

In January 2017, the Consultant’s Competitive Compensation Assessment revealed that the target bonus amounts for the Company’s executive officers, including the NEO’s, were between the 25th and 50th percentile of the Peer Group. Successful achievement of the aggressive performance targets adopted in the Company’s annual bonus plan has increased shareholder value over the last several years, and the Compensation Committee determined that target bonus amounts should reflect that success by being at or above the Peer Group median.

Annual incentive compensation targets under the Annual Bonus Plan are expressed as a percentage of annual cash salary, and bonus targets, achievements and payouts are included as shown in the following table.



Name	Target (% of Actual Salary)		2017 Bonus Earned ($)	2017 Bonus Paid ($)	2017 Bonus Paid (as % of Target)

Long-Term Equity Incentive Compensation

The Company considers long-term equity incentive compensation (“LTI”) critical to the alignment of executive compensation with stockholder value creation and an integral part of the Company’s overall executive compensation objectives. The Compensation Committee approves annual equity grants at its January meeting, except with respect to the CEO and Executive Chairman, whose annual grants are approved by the Board of Directors at its January meeting. The grant date for the annual equity grant for all NEOs is the day of the Board of Directors’ January meeting.

As mentioned above, the Compensation Committee and the CEO believe EPS is the best measure of the Company’s success and ability to deliver value to shareholders. Reaching long-term EPS goals is critical to the Company’s growth strategy, and the EPS targets are designed to deliver performance better than the Peer Group. The Company has reliably delivered outstanding results to shareholders by focusing on this superior EPS strategy. Therefore, in both 2017 and 2018, the Company continued to design its performance-based equity awards primarily around the achievement of specified EPS targets. However, the Compensation Committee also recognizes the importance of TSR, especially in light of the SEC’s proposed “Pay for Performance” rules. In order to ensure the Compensation Committee is in the best position to establish meaningful performance targets both now and in the future, in 2016 the Committee engaged the Consultant to review and provide a recommendation on whether one or more TSR measures should be part of the Company’s LTI program. Pursuant to that review, a relative TSR carve-out was adopted by the Committee in 2017, as explained below.

2017 LTI Determination:

Given the ongoing success of the Company’s pay-for-performance approach, the Compensation Committee decided to continue granting performance-based stock unit awards (“PSUs”) to Company executives in 2017. The Compensation Committee believes that performance-based shares connect executive’s individual interests and the long term success of the Company. After considering information regarding market analysts’ expectations for the Peer Group and the Company and input from Mr. Sarver and the Consultant, the Committee decided that the performance targets for the PSUs covering the 2017-2019 performance period would be weighted 75% toward the Company’s three-year cumulative EPS and 25% toward the Company’s relative TSR compared to the KBS Regional Banking Index. At the end of the performance period, the Company’s actual performance against the performance targets will be computed separately, then added together to obtain the total number of shares awarded.

The Committee approved the following performance targets for the 2017-2019 performance period:

Cumulative EPS (75%):



PSU Vesting (%)	Target ($)
—%	<$8.70
50%	$	8.70
100%	$	9.30
200%	$10.05 or above



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	30



Table of Contents

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

Relative TSR (25%) compared to the KBW Regional Banking Index:



TSR (%)	KBW Regional Banking Index (percentile)
—%	<25th
50%	25th
100%	50th
200%	75th

Each NEO is awarded a target number of PSUs; however, the actual number of shares of common stock received will depend on the Company’s actual performance at the end of the 3-year performance period. The PSUs will be forfeited, and the accounting expense reversed, if the established threshold performance goals are not achieved or in event of termination of employment that is not in connection with a Change in Control (as defined in the 2005 Stock Incentive Plan).

With respect to restricted stock awards (“RSAs”), in 2015 the Compensation Committee began adding an EPS performance component to RSAs for executives with bonus targets of 65% and higher. The EPS hurdle for these RSAs is not intended to be a target or stretch goal, but simply serves as another connection between the interests of shareholders and executives. The Compensation Committee continued that approach in 2017 and approved performance-based restricted stock awards for Messrs. Sarver, Vecchione, Gibbons, Haught and Myers that required the Company to achieve a one-year EPS target of $2.03 before the award became eligible to vest on the second and third anniversaries of the grant.

Based on the Compensation Committee’s recommendation, in 2017, the Board of Directors granted Mr. Sarver 30,690 Performance-Based RSAs, and 30,690 PSUs. The Committee’s recommendation was in keeping with its desire to align Mr. Sarver’s target total direct compensation with the top quartile of the Peer Group. Messrs. Gibbons, Haught and Myers also received a combination of RSAs and PSUs with the same measures provided above, and in amounts commensurate with their position and responsibilities within the Company.

In connection with the Company's CEO succession planning, and to recognize and reward Mr. Vecchione's commitment to return to the Company to offset the loss of equity value at his previous company, the Compensation Committee recommended and the Board approved a one-time grant of 100,000 Performance-Based RSAs to Mr. Vecchione in 2017, vesting 25% per year over a four year period.



Name	Performance-Based RSAs (#)	PSUs (#)
Vecchione	100,000	—
Sarver	30,690	30,690
Gibbons	5,940	6,600

2018 LTI Determination

In 2018, after considering information regarding market analysts’ expectations for the Peer Group and the Company and input from Messrs. Sarver and Vecchione and the Consultant, the Committee designed performance targets for the PSUs covering the 2018-2020 performance period in the same way as the 2017-2019 PSUs, weighted 75% toward the Company’s three-year cumulative EPS and 25% toward the Company’s relative TSR compared to the KBS Regional Banking Index. At the end of the performance period, the Company’s actual performance against the performance targets will be computed separately, then added together to obtain the total number of shares awarded.

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

The Committee approved the following performance targets for the 2018-2020 performance period:

Cumulative EPS (75%):



PSU Vesting (%)	Target ($)
—%	<$12.00
50%	$	12.00
100%	$	12.75
200%	$13.65 or above

TSR (%)	KBW Regional Banking Index (percentile)
—%	<25th
50%	25th
100%	50th
200%	75th

The relative TSR component of LTI will be subject to a 100% maximum if TSR is negative for the performance period. The Company will interpolate on a straight-line basis between the threshold, target and maximum in each category of performance. Other than the revised performance targets, the 2018 PSUs have the same terms as the 2017 performance shares.

The Compensation Committee did not establish a performance hurdle for the restricted stock awards for Messrs. Vecchione, Sarver, Gibbons, Haught and Myers in 2018. Following the changes to Section 162(m) in December 2017, the Compensation Committee decided that 2018 restricted stock awards would continue to serve the purpose of retaining executives and rewarding them for the performance of the Company if they followed a standard vesting schedule on the second and third anniversaries of the grant.

In accordance with his Offer Letter, the Board of Directors granted Mr. Vecchione the number of PSUs equivalent to $1.1 million and RSAs equivalent to $1.1 million on the date of grant. Similarly to the discussion of Mr. Sarver's base salary above, the Board approved the Compensation Committee’s recommendation that Mr. Sarver's 2018 equity award equal 75% of the grant date fair value of his 2017 equity award, split equally between PSUs and RSAs, was in keeping with its desire to align Mr. Sarver’s target total direct compensation with the top quartile of the Peer Group. The remaining NEOs also received a combination of RSAs and PSUs with the same measures provided above, and in amounts commensurate with their position and responsibilities within the Company.



Name	RSAs (#)	PSUs (#)
Vecchione	18,803	18,803
Sarver	19,231	19,231
Gibbons	6,000	6,000
Haught	6,000	6,000
Myers	3,282	3,282

The Company has a compensation recovery policy that would apply if the result of a performance measure upon which an award was based is subsequently restated or otherwise adjusted in a manner that would reduce the size of the award or payment. The Compensation Committee, in its sole discretion, may direct the Company to recover any portion of any annual or long-term cash, equity or equity-based incentive paid, provided or awarded to any executive officer, including our NEOs, that represents the excess over what would have been paid if such event had not occurred.

Executive Officer Stock Ownership Guidelines

The Board of Directors adopted Stock Ownership Guidelines in 2010. The Stock Ownership Guidelines, as amended, require the Company’s executive officers to own a minimum number of shares of the Company’s common stock, depending on their position and compensation level. Each actively employed NEO is required to remain in full compliance with these requirements.



Name	Ownership Guidelines	Status
Sarver	5x base salary	Met
Vecchione	5x base salary	Met
Gibbons	4x base salary	Met
Haught (1)	4x base salary	Met
Myers	3x base salary	Met

(1) Mr. Haught joined the Company as an Executive Officer in 2017 and is, therefore, within his five year compliance phase-in period.

The Company’s Insider Trading Policy and Stock Ownership Guidelines prohibit all executive officers from engaging in any hedging involving Company securities. In addition, the Stock Ownership Guidelines restrict the pledging of Company securities by all directors and executive officers (as defined by Section 16 of the Exchange Act).

Benefits and Perquisites

With limited exceptions, the Company offers executives the same basic benefit plans that are available to all full time employees (e.g., participation in our 401(k) Plan and group insurance plans for medical, dental, vision care and prescription drug coverage; basic life insurance; long term disability coverage; holidays; vacation, etc.), plus voluntary benefits that an executive may select and pay for (e.g., supplemental life insurance). The Company’s overall benefits philosophy is to focus on the provision of core benefits, with executives able to use their cash compensation to obtain such other benefits as they individually determine to be appropriate for their situations.

The Company believes in a compensation philosophy that deemphasizes benefits and perquisites for NEOs in favor of the performance-based compensation approach described above. The Company does not pay gross-ups and overall perquisites for NEOs continue to be minimal and limited to business-related functions and responsibilities. Please see footnote 3 to the Summary Compensation Table below for more information regarding perquisites offered to our NEOs.

Non-Qualified Deferred Compensation Plan

NEOs may voluntarily defer cash compensation as part of the Western Alliance Bancorporation Nonqualified 401(k) Restoration Plan (“Restoration Plan”). The Restoration Plan was adopted in order to allow the executive officers to defer a portion of their compensation because they face statutory limits under the Company’s 401(k) Plan. We believe the Restoration Plan is a cost-effective method of providing a market-competitive benefit to the NEOs. For more information on the Restoration Plan, including amounts deferred by the NEOs in 2017, see the Deferred Compensation Plan table and accompanying narrative below.

Bridge Bank, National Association Supplemental Executive Retirement Plan

Each of the prior named executive officers of Bridge Capital Holdings, including Mr. Myers, were eligible to participate in the Bridge Bank, National Association Supplemental Executive Retirement Program (the “SERP”). In connection with the Company’s acquisition of Bridge Capital Holdings and Bridge Bank, National Association, the Company assumed the SERP. Under the SERP, after achieving defined length of service and vesting thresholds, Mr. Myers and the other participating Bridge Bank executives will receive fifteen annual payments upon reaching retirement. The retirement payment is based on the average base salary of the employee in the last three years of service. The level of the retirement payment increases at a rate of four percent of base salary per year of service, cumulatively, until reaching a level of 60% after fifteen years of service. The executive’s right to receive retirement payments vests over a period of ten years of continuous service, including years served at Bridge Bank.

EXECUTIVE COMPENSATION • COMPENSATION DISCUSSION AND ANALYSIS

Tax Considerations

Section 162(m) of the Internal Revenue Code (Section 162(m)) generally disallows a tax deduction to a company for compensation in excess of one million dollars paid to a company's CEO, and to the next four highest paid officers of the company, unless the compensation qualifies as "performance-based compensation" or falls under certain other specified exceptions under Section 162(m). Generally, to qualify as performance-based compensation, the plan or arrangement must contain specific performance criteria, specific limits on awards and amounts and must have shareholder approval. We have historically structured incentive compensation arrangements with a view toward qualifying them as performance-based compensation exempt from the deduction limitations under Section 162(m), although we have viewed and continue to view the availability of a tax deduction as only one relevant consideration. The Compensation Committee believes that its primary responsibility is to provide a compensation program that attracts, retains and rewards the executive talent necessary for our success.

Federal tax legislation enacted in December 2017 eliminated the Section 162(m) performance-based compensation exemption prospectively and made other changes to Section 162(m), but with a transition rule that preserves the performance-based compensation exemption for certain arrangements and awards in place as of November 2, 2017. We intend to continue to administer arrangements and awards subject to this transition rule with a view toward preserving their eligibility for the performance-based compensation exemption to the extent practicable and consistent with the non-tax compensation program objectives noted above.

Furthermore, the Compensation Committee considered other tax and accounting provisions in developing the pay programs for the Company’s NEOs. These included special rules applicable to nonqualified deferred compensation arrangements under Code Section 409A and the accounting treatment of various types of equity-based compensation under FASB ASC Topic 718, as well as the overall income tax rules applicable to various forms of compensation. While the Company attempted to compensate executives in a manner that produced favorable tax and accounting treatment, its main objective was to develop fair and equitable compensation arrangements that appropriately reward executives for the achievement of short- and long-term performance goals.

Evaluation of Company Compensation Plans and Risk

The Compensation Committee engages in a comprehensive review of the Company’s employee incentive plans no less often than annually. In April 2017, the Compensation Committee met with the Company’s CFO and senior risk officers to discuss, evaluate and review all of the Company’s employee compensation plans. The Compensation Committee and senior risk officers identified potential risks posed to the Company and risk mitigating factors within the plans. Based on input regarding long-term and short-term risks to the Company, the Committee ensured the plans include guiding principles, limitations on eligibility, clawbacks and other features, as necessary, to focus employees on long-term value creation rather than short-term results. Based on its most recent review of the compensation plans, an evaluation of the amount of payments made and the number of employees eligible for each plan, and discussions with the Company’s senior risk officers regarding the potential risks and how those risks are limited for each plan, the Compensation Committee determined that none of the Company’s compensation programs are reasonably likely to have a material adverse effect on the Company.

Compensation Committee Report

The Compensation Committee reviewed and discussed the Compensation Discussion and Analysis included in this proxy statement with management. Based on such review and discussion, the Compensation Committee recommended to the Board of Directors that the “Compensation Discussion and Analysis” be included in this proxy statement for filing with the SEC, and incorporated by reference into our Annual Report on Form 10-K.

Stock awards consist of performance-based restricted stock and stock units. The amounts represent the grant date fair value of the stock awards issued during the applicable fiscal year. With respect to the performance-based stock units, the amounts disclosed represent the aggregate grant date fair value of the award computed in accordance with FASB ASC Topic 718 at the target level of payout. The value of the 2017, 2016 and 2015 performance-based stock unit awards based on maximum performance as of the grant date was: Mr. Sarver – $2,987,978, $2,513,600, and $2,127,200; Mr. Gibbons – $642,576, $565,560, and $531,800; Mr. Haught - $484,407, $0, and $0; Mr. Myers – $372,013, $360,010 and $0. Mr. Vecchione did not have performance-based stock unit awards granted in 2017 or in the prior years. The Grants of Plan-Based Awards During 2017, Outstanding Equity Awards at Fiscal Year End and the Option Exercises and Stock Vested in 2017 tables include additional information with respect to all awards outstanding as of December 31, 2017.

Each participant who received a performance-based stock unit award was awarded a specific number of target units that will be earned by the participant at the end of a three-year performance period based on the Company’s cumulative EPS. Please refer to the “Long-Term Incentive Compensation” section of the CD&A in this proxy statement for more details regarding this equity program.


(2)	The Non-Equity Incentive Plan Compensation was fully payable as of December 31, 2017, and may not be deferred at the election of the NEO. The amounts reported in this column consist of earnings pursuant to the Annual Bonus Plan for the year indicated.

(3)

The amounts shown in this column represent the aggregate change in actuarial present value of accumulated pension benefits for the named executive officer participating in the company’s SERP. The SERP was assumed in the acquisition of Bridge Capital Holdings on June 30, 2015, therefore, the only named executive officer participating in the SERP is Mr. Myers. For 2016 and 2017, the value listed in this column represents the change in the present value of accumulated benefits for the full calendar year, whereas, for 2015, the change in value is from the June 30, 2015 acquisition date to December 31, 2015. The amounts represented above may fluctuate significantly in a given year depending on a number of factors that affect the formula to determine pension benefits, including years of service, earnings and actuarial assumptions. The discount rate of 5.75% used to determine the present value of the accumulated benefit was unchanged from 2015 to 2016. The salary rate increase was updated from the 4.00% used in 2015 and 2016 to 3.00% in 2017. The Company has not provided above-market or preferential earnings on non-qualified deferred compensation under its Restoration Plan and, accordingly, no such amounts are reflected in this column.

Non-Equity Incentive Plan Awards (Columns 3-5) The amounts reported in these columns reflect threshold, target and maximum award amounts for fiscal year 2017 pursuant to the 2017 Western Alliance Bancorporation Annual Bonus Plan, which is a performance-based compensation plan. The actual amounts earned by each NEO pursuant to such plan are set forth in the Non-Equity Incentive Compensation Column of the Summary Compensation Table.

Equity Incentive Plan Awards (Columns 6-8) The amounts reported in these columns reflect threshold, target and maximum award amounts for the 2017-2019 performance cycle pursuant to the PSUs issued as part of our 2017 annual equity awards. The actual amounts, if any, earned by each NEO pursuant to such awards are determined by the Compensation Committee at the end of the three-year performance cycle and are based on the Company’s cumulative EPS during the performance period. Threshold, target and maximum award amounts are payable upon achievement of a cumulative EPS of $8.70, $9.30, and $10.05, respectively. For more information regarding performance unit awards, please refer to the Long-Term Incentive Compensation section of the CD&A.

Stock Awards and Option Awards (Columns 9) The amounts reported in the 9th column reflect the number of shares underlying restricted stock awards that were granted as part of our 2017 annual equity awards and were subject to a one-year performance hurdle of EPS equal to or greater than $2.03, before becoming eligible to vest. Upon eligibility, they will vest 50% on the second and third anniversaries of the grant date.

Grant Date Fair Value (Column 10) In the case of PSUs issued as part of our 2017 annual equity awards, the grant date fair value is based on the maximum number of shares, which the Company currently estimates as a probable outcome of the market-based performance conditions. Depending on whether or to what extent the respective performance conditions are met, the number of shares for which the performance units are settled may range from zero to 200%.

Outstanding Equity Awards at Fiscal Year End

The following table provides information concerning outstanding stock option awards and unvested RSAs and PSUs held by each NEO as of December 31, 2017. Each outstanding award is represented by a separate row which indicates the number of securities underlying the award.

Nonqualified Deferred Compensation in 2017

The Company sponsors the Restoration Plan, a non-qualified deferred compensation plan available only to certain executives. The Restoration Plan became effective in 2006. Under the 401(k) Plan, there is a statutory limit on the amount of compensation that can be taken into consideration in determining participant contributions and the Company’s matching contributions. The Restoration Plan allows participants to contribute 6% of their base salary and bonus compensation payable under the Annual Bonus Plan, without regard to the statutory compensation limit, but offset by participant contributions actually made under the 401(k) Plan. The Company makes matching contributions of 50% of the deferred amount up to 3% of all compensation as offset by the amount of matching contributions made on the participant’s behalf under the 401(k) Plan.

The following table provides information with respect to the Restoration Plan. The amounts shown include compensation earned and deferred in prior years, and earnings on, or distributions of, such amounts. The column “Executive Contributions in 2017” indicates the aggregate amount contributed to such plans by each NEO during 2017. In 2017, no NEO received preferential or above-market earnings on deferred compensation, and no withdrawals or distributions were made.

CEO Pay Ratio



We are committed to internal pay equity, and the Compensation Committee monitors the relationship between the pay our executive officers receive and the pay our non-managerial employees receive. The Compensation Committee reviewed a comparison of CEO pay to the pay of all our employees in 2017. The compensation for our CEO in 2017 was approximately 69 times the median pay of our full-time employees.	69:1 CEO Pay Ratio

Our CEO to median employee pay ratio is calculated in accordance with Item 402(u) of Regulation S-K. We identified the median employee by examining the total compensation for all individuals, excluding Mr. Sarver, who were employed by us on December 1, 2017. To determine total compensation, we used: (1) the W-2 Gross Wages amount for all active employees who were employed during the entire 2017 calendar year; and (2) the annualized gross compensation amount for mid-year hires using December 1, 2017 payroll data. We included all employees, whether employed on a full-time, part-time, or seasonal basis. We did not include retired employees or employees on long term leaves of absence who may have received compensation during the course of the year. We did not make any assumptions, adjustments, or estimates with respect to total cash or equity compensation, other than annualizing the compensation for any active employees that were not employed by us for all of 2017.

After identifying the median employee based on total compensation, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as set forth in the 2017 Summary Compensation Table later in this proxy statement.

Accordingly, our median employee for 2017 received total compensation in the amount of $83,150, whereas our CEO's total compensation for 2017 totaled $5,745,870, such that our 2017 CEO to median employee pay ratio was 69:1.

For purposes of the Employment Agreement, "Good Reason" means that, without Mr. Myers’ written consent, there occurs (i) any material adverse change in the nature and scope of Mr. Myers' position, authorities, responsibilities, duties, or a change of thirty (30) miles or more in Mr. Myers' location of employment, or any material reduction in Mr. Myers’ base salary, bonus or other benefits, or (ii) any event which reasonably constitutes a demotion, significant diminution or constructive termination (by resignation or otherwise) of Mr. Myers' employment.

Pursuant to the Protection Agreement, in the event Mr. Myers is terminated following his third anniversary with the Company, but before his fifth anniversary with the Company, the Company shall (i) provide Mr. Myers with salary continuation payments equal to his base salary, if any, for the period from the termination date through his fifth anniversary with the Company; and (ii) cause the vesting of his restricted stock awards scheduled to vest on the fifth anniversary of his employment with the Company to accelerate as of the date of termination of service. Mr. Myers shall not receive payments pursuant to the Protection Agreement if his employment with the Company terminates for any of the following reasons: (a) the loss by Mr. Myers of legal capacity; (b) the willful, intentional and material breach or the habitual and continued neglect by Mr. Myers of his duties and responsibilities; (c) the continuous mental or physical incapacity of Mr. Myers; (d) the willful and intentional violation of any state or federal banking or securities laws, or of the bylaws, rules, policies or resolutions of the Company or its subsidiaries, or the rules of a regulatory agency or governmental authority having jurisdiction over the Company or its subsidiaries; (e) the written determination by a state or federal regulatory agency or governmental authority that Mr. Myers is not suitable to act in the capacity in which he serves the Company; (f) Mr. Myers’s conviction of (i) any felony or (ii) a crime involving moral turpitude, or Mr. Myers' willful and intentional commission of a fraudulent or dishonest act; or (g) Mr. Myers' non-insurability for surety bond coverage as determined in the sole discretion of the Company’s insurer at any time. Payments shall also be due to Mr. Myers if he resigns for "Good Reason", which has the same meaning as under the Employment Agreement.

With respect to Messrs. Sarver, Gibbons, and Haught, no current employment agreements are in place providing for payments for termination outside of a change in control.

Potential Payments upon Termination in the Event of a Change in Control

In 2012, the Board of Directors adopted the Western Alliance Bancorporation Change in Control Severance Plan (“CIC Plan”) for its executive officers; therefore, all NEOs are eligible for change in control severance benefits payable pursuant to the CIC Plan. Under the CIC Plan, benefits are payable to eligible executives, including NEOs, only if the plan’s double trigger requirements are satisfied, meaning that, in order to receive any of the following benefits, the executive’s employment must be terminated without cause or the executive must terminate his employment for good reason during the 24-month period following a Change in Control.

A Change in Control is defined as:


•	the dissolution or liquidation of the Company or a merger, consolidation, or reorganization of the Company with one or more other entities in which the Company is not the surviving entity;


•	a sale of all or substantially all of the assets of the Company to another person or entity; or


•	any transaction, including a merger or reorganization, in which the Company is the surviving entity, which results in any person or entity other than persons who are stockholders or affiliates immediately prior to the transaction owning 50% or more of the combined voting power of all classes of stock of the Company.

Severance benefits under the CIC Plan consist of:


•	a single lump sum cash severance payment in an amount equal to the sum of (i) two times the executive’s base salary, and (ii) two times the executive’s target incentive bonus amount;


•	payment of any annual bonus that the executive earned in the prior year, but which was unpaid as of the executive’s separation from service;


•	payment of a pro rata amount of the executive’s target incentive bonus amount for the year in which the executive’s separation from service occurs, based on the number of days elapsed in the year; and



	WESTERN ALLIANCE BANCORPORATION 2018 PROXY STATEMENT	41

EXECUTIVE COMPENSATION • POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL


•	payment of the Company’s portion of the cost of continuing coverage under the Company’s group health benefit plan for the executive and the executive’s family for a period of up to 24 months.

The payment of benefits under the CIC Plan is conditioned upon the executive executing a general release in favor of the Company and is subject to the terms of the non-competition, non-solicitation and confidentiality covenants agreed to between each executive and the Company.

The 2005 Stock Incentive Plan provides for the treatment of outstanding options and shares of restricted stock upon the occurrence of a Change in Control. In the event of a Change in Control, unless the successor entity or a parent or subsidiary thereof has agreed in writing to assume or continue the Company’s outstanding stock options and restricted stock awards or to substitute new awards to replace such outstanding awards of the Company, then the outstanding stock options and unvested restricted stock awards will vest in full, and the Board of Directors may elect, in its sole discretion, either to provide that all stock options will be exercisable for a period of 15 days prior to, and contingent upon, the consummation of the Corporate Transaction or to cancel any outstanding options and restricted stock in exchange for an amount of cash or securities. With respect to performance shares, the stock unit agreements provide that, in the event of a Change in Control, the vesting of the 2015, 2016 and 2017 performance shares shall be determined based on performance for the portion of the performance period that elapsed prior to the Change in Control.

Under the Restoration Plan, the Company’s matching contribution in the executive’s account (and all earnings thereon) will become 100% vested immediately (if not already vested) upon a change in control of the Company.

Assuming a change in control or other vesting event occurred on December 31, 2017, the vesting benefit pursuant to the Restoration Plan to each NEO would have been $0 for Mr. Vecchione, $918,692 for Mr. Sarver, $237,913 for Mr. Gibbons, $0 for Mr. Haught, and $39,469 for Mr. Myers.

The table below reflects the amount of compensation that would have become payable to each of our NEOs under existing plans if the NEO’s employment had been involuntarily terminated or the NEO resigned for good reason immediately following a Change in Control on December 31, 2017. The actual amounts that would be paid upon a NEO’s termination of employment or in connection with a Change in Control can be determined only at the time of any such event. Due to a number of factors that may affect the amount of any benefits provided upon the events discussed below, actual amounts paid or distributed may be higher or lower than indicated in the table. Factors that could affect these amounts include the timing during the year of any such event, our stock price, the attained level of performance for performance units, and any additional agreements or arrangements we may enter into in connection with any change in control or termination of employment. For a more complete understanding of the table, please read the narrative disclosures that follow the table.



Name	Cash Severance ($)	Bonus ($)	Stock Awards ($)	Welfare & Other Benefits ($)	Total ($)
Kenneth Vecchione	4,000,000	1,263,090	5,662,000	14,933	10,940,023
Robert Sarver	4,800,000	1,486,560	11,780,923	25,566	18,093,049

Daniel Myers	1,534,500	381,295	2,471,463	25,566	4,412,824

Cash Severance (Column 2) The cash severance amount upon a change in control termination represents a lump sum payment equal to the sum of (i) two times the executive’s base salary as of December 31, 2017, and (ii) two times the executive’s the target incentive bonus amount under the 2017 Annual Bonus Plan.

Bonus (Column 3) The bonus amount represents the pro-rata payment of the annual bonus based on the number of days that the NEO was employed by the Company during the fiscal year. Because we have assumed that the applicable termination of employment occurred on the last day of our 2017 fiscal year, the amounts reported in this column represent the full annual bonus award payable to each NEO for 2017.

Stock Awards (Column 4) The amounts reported represent the value that would have been attained upon the full vesting of all unvested restricted stock and performance share awards held by the NEO as of December 31, 2017. Amounts attributable to performance shares are based on the assumption for the 2016 and 2017 performance share

awards would have vested based on achievement of maximum performance. The value of each share of restricted stock and performance shares subject to accelerated vesting is equal to our common stock’s closing market price per share of $56.62 on December 29, 2017.

Welfare & Other Benefits (Column 5) The welfare benefits amount represents the employer portion of the premium paid on behalf of the NEO for continued coverage under the Company’s medical, dental and vision plans during the applicable severance period. Amounts are based on premiums paid on the executive’s behalf in 2017.

Additionally, each of Mr. Myers’ Employment Agreement and Protection Agreement contain certain non-compete terms, with the Employment Agreement restricting Mr. Myers from competing with the Bank and its affiliates, and the Protection Agreement binding Mr. Myers to certain non-competition, non-solicitation and non-disparagement covenants.

In consideration for the Company making certain executive officers, including the NEOs, eligible for the severance benefits provided pursuant to the Company’s CIC Plan, each executive is subject to the terms of certain non-competition, non-solicitation and confidentiality covenants by and between the executive and the Company, pursuant to which the executive agrees not to disclose confidential Company information at any time and not to compete with the Company nor solicit our employees or customers for a period of one year following termination of employment.

Indemnification Agreements

On February 28, 2017, the Company entered into indemnification agreements with each of the Company’s directors and executive officers (“indemnitees”) that provide contractual assurance of the indemnification authorized and provided for by the Certificate of Incorporation and Bylaws and the manner of such indemnification.

Certain Transactions with Related Persons

The Company and its banking subsidiaries have engaged in, and in the future expect to engage in, banking transactions in the ordinary course of business with directors, officers, and principal stockholders of the Company and its subsidiaries (and their associates), including corporations, partnerships and other organizations in which such persons have an interest. See “Compensation Committee Interlocks and Insider Participation” on page 20 for more information on these banking transactions.

Other than such banking transactions, there have been three related person transactions since the beginning of fiscal 2017: first, the Company’s bank subsidiary purchased season tickets for the Phoenix Suns’ 2018-2019 season for a total amount of $332,277. Mr. Sarver is the Managing Partner of the entity which owns the Phoenix Suns NBA basketball team, and Mr. Hilton is a limited partner in the Phoenix Suns ownership group. The tickets are used for business development purposes.

EXECUTIVE COMPENSATION • POLICIES AND PROCEDURES REGARDING TRANSACTIONS WITH RELATED PERSONS

Policies and Procedures Regarding Transactions with Related Persons

In January 2018, the Board of Directors updated its Related Party Transactions Policy (“Policy”) that can be found in the Governance Documents section of the Investor Relations page of the Company’s website at www.westernalliancebancorporation.com or, for print copies, by writing to the Company at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, Attention: Corporate Secretary.

The Policy applies only to specific transactions or arrangements with so-called related parties, which includes the Company’s directors, executive officers, beneficial owners of 5% of more of the Company’s voting securities, related entities, and immediate family members of the foregoing. In general, under the Policy, unless the transaction is deemed to be pre-approved under the Policy, every transaction involving a related party that involves amounts greater than $120,000 must be approved by the Governance Committee.

In accordance with Federal Reserve Board Regulation O, the Company’s bank subsidiary has adopted a formal policy governing any extensions of credit to any executive officer, director or significant stockholder of the bank or any affiliate. These policies require, among other things, that any such loan (1) be made on substantially the same terms (including interest rates, collateral and repayment terms) as those prevailing at the time for comparable transactions with unrelated persons, (2) not involve more than the normal risk of collectability or present other unfavorable features for the bank, and (3) be approved by a majority of the bank’s full board of directors, without the direct or indirect participation of the interested person. Any transactions between the Company and an officer or director of the Company (or any of its affiliates), or an immediate family member of such an officer or director, falling outside the scope of these formal policies must be conducted at arm’s length. Any consideration paid or received by the Company in such a transaction must be on terms no less favorable than terms available to an unaffiliated third party under similar circumstances.

ITEMS OF BUSINESS TO BE ACTED ON AT THE MEETING • PROPOSAL NO. 2. ADVISORY (NON-BINDING) VOTE ON EXECUTIVE COMPENSATION

Proposal No. 2. Advisory (Non-Binding) Vote on Executive Compensation

Section 14A of the Exchange Act requires that our stockholders have the opportunity to cast an advisory (non-binding) vote on executive compensation, no less than once every three years. Consistent with the desire of the Company’s stockholders expressed at the 2012 Annual Meeting of Stockholders to conduct the advisory vote on executive compensation annually, the Company has elected to provide for annual votes on executive compensation.

Accordingly, we ask our stockholders to vote on the following resolution at the Annual Meeting:

RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2018 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the 2017 Summary Compensation Table and other related tables and disclosures therein.

Our executive compensation policies are designed to establish an appropriate relationship between executive pay and the annual and long-term performance of the Company and its affiliates, to reflect the attainment of short- and long-term financial performance goals, to enhance our ability to attract and retain qualified executive officers, and to align to the greatest extent possible interests of management and stockholders. Our Board of Directors believes that our compensation policies and practices achieve these objectives.

Because your vote is advisory, it will not be binding upon the Board of Directors. However, the Board of Directors and Compensation Committee may take into account the outcome of the vote when considering future executive compensation arrangements.

The Board of Directors unanimously recommends that the stockholders vote “FOR” the approval of

the compensation of our named executive officers, as disclosed in this proxy statement.

As described in Proposal No. 2, the Section 14A of the Exchange Act also requires that we include in this proxy statement for our 2018 Annual Meeting, a separate advisory (non-binding) vote on whether the vote on executive compensation should occur every one, two or three years. Stockholders have the option to vote for any one of the three options or abstain on the matter. We are required to solicit stockholder approval on the frequency of future advisory executive compensation proposals at least once every six years, although we may seek stockholder input more frequently.

The option of one year, two years or three years that receives the greatest number of votes by shares present in person or represented by proxy and entitled to vote will be deemed the frequency for the advisory vote on the compensation of our named executive officers that has been selected by stockholders. However, because this vote is advisory and is not binding on our Board of Directors, the Board may decide that it is in the best interests of us and our stockholders to hold an advisory vote on executive compensation more or less frequently than the option approved by our stockholders.

The Board believes that these votes should occur every year so stockholders may annually express their views on our executive compensation program. The Board values the opportunity to get feedback and will continue to consider the outcome of these votes in making executive compensation decisions.

The Board of Directors unanimously recommends that the stockholders vote to hold the non-binding vote on executive compensation “Every Year”.

Stockholder Proposals for the 2019 Annual Meeting

Any proposal which a stockholder wishes to have included in the Company’s proxy statement and form of proxy relating to its 2019 Annual Meeting of stockholders must be received by the Company in writing on or before the close of business on December 28, 2018 and the proposal must otherwise comply with Rule 14a-8 under the Exchange Act, including the proof of ownership requirements of Rule 14a-8(b)(2), and Delaware law. Proposals must be addressed to the Corporate Secretary at the Company’s principal executive offices located at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004.

Failure to deliver a proposal in accordance with these procedures may result in it not being deemed timely received. Submitting a stockholder proposal does not guarantee that we will include it in our proxy statement. Our Governance Committee reviews all stockholder proposals and makes recommendations to the Board of Directors for actions on such proposals. For information on qualifications of director nominees considered by our Governance Committee, see the “Corporate Governance – Director Selection Process” section of this proxy statement.

In addition, under our Bylaws, any stockholder who intends to nominate a candidate for election to the Board of Directors or to propose any business at our 2019 Annual Meeting that is not to be included in the proxy statement, must give notice to our Corporate Secretary between February 12, 2019 and the close of business on March 14, 2019. The notice must include information specified in our Bylaws, including information concerning the nominee or proposal, as the case may be, and information about the stockholder’s ownership of and agreements related to the Company’s stock. If the 2019 annual meeting is held more than 30 days from the anniversary of the 2018 Annual Meeting of stockholders, the stockholder must submit notice of any such nomination and of any such proposal that is not to be included in the proxy statement by the later of the 90th day before the 2019 Annual Meeting or the 10th day following the day on which the date of such meeting is first publicly announced. We will not entertain any proposals or nominations at the 2019 Annual Meeting that do not meet the requirements set forth in our Bylaws. If the stockholder does not also

comply with the requirements of Rule 14a-4(c)(2) under the Securities Exchange Act of 1934, as amended, the Company may exercise discretionary voting authority under proxies that we solicit to vote in accordance with our best judgment on any such stockholder proposal or nomination. The Company strongly encourages stockholders to seek advice from knowledgeable counsel before submitting a proposal or a nomination.

Annual Report on Form 10-K

The Company has filed its Annual Report on Form 10-K for its 2017 fiscal year with the SEC. Stockholders may obtain, free of charge, a copy of the Form 10-K by writing to the Company at One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, Attention: Corporate Secretary, or from the website www.proxyvote.com.

Legal Proceedings

No director or executive officer of the Company is a party to any material pending legal proceedings or has a material interest in any such proceedings that is adverse to the Company or any of its subsidiaries.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for annual reports, proxy statements, and Notices of Internet Availability of Proxy Materials with respect to two or more stockholders sharing the same address by delivering a single annual report, proxy statement, or Notice of Internet Availability of Proxy Materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. Brokers with account holders who are stockholders of the Company may be householding the Company’s proxy materials. Once you have received notice from your broker that it will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate annual report, proxy statement, or Notices of Internet Availability of Proxy Materials or if you are receiving multiple copies thereof and wish to receive only one, please notify your broker or notify the Company by sending a written request to Western Alliance Bancorporation, One E. Washington Street, Suite 1400, Phoenix, Arizona 85004, Attn: Corporate Secretary, or by calling (602) 389-3500.

Other Business

Except as described above, the Company knows of no business to come before the Annual Meeting. However, if other matters should properly come before the Annual Meeting or any adjournment thereof, it is the intention of the persons named in the proxy to vote in accordance with the determination of a majority of the Board of Directors on such matters.
