During 2013, Synovus made a number of accomplishments as we continued to recover from a challenging economy, the most significant of which was the redemption of our obligations under the Troubled Asset Relief Program, or TARP. Our key achievements in 2013 include the following:

Our 2013 year-end stock price also reflects our 2013 results, ending the year at $3.60 per share on December 31, 2013, an increase of 47% from our $2.45 per share price on December 31, 2012.

For more information regarding 2013 financial performance, please refer to the full discussion of Synovus’ financial results of operations for 2013 in our 2013 Annual Report that accompanies this Proxy Statement.

You received this Proxy Statement and the accompanying proxy card because the Board of Directors of Synovus Financial Corp., or Synovus, is soliciting proxies to be used at Synovus’ 2014 Annual Meeting of Shareholders, or Annual Meeting, which will be held on April 24, 2014, at 10:00 a.m., at the Columbus Georgia Convention and Trade Center,

801 Front Avenue, Columbus, Georgia 31901. Proxies are solicited to give all shareholders of record an opportunity to vote on matters to be presented at the Annual Meeting. In the following pages of this Proxy Statement, you will find information on matters to be voted upon at the Annual Meeting or any adjournment of that meeting.

As permitted by the federal securities laws, Synovus is making this Proxy Statement and its 2013 Annual Report on Form 10-K, or 2013 Annual Report, available to its shareholders via the Internet instead of mailing printed copies of these materials to each shareholder. On March 14, 2014, we mailed to our shareholders (other than those who previously requested electronic or paper delivery and other than those holding a certain number of shares) a Notice of Internet Availability, or Notice, containing instructions on how to access our proxy materials, including this Proxy Statement and the accompanying 2013 Annual Report. These proxy materials are being made available to our shareholders on or about March 14, 2014. The Notice also provides instructions regarding how to access your proxy card to vote through the Internet or by telephone. The

Proxy Statement and 2013 Annual Report are also available on our website at www.synovus.com/2014annualmeeting.

If you received a Notice by mail, you will not receive a printed copy of the proxy materials by mail unless you request printed materials. If you wish to receive printed proxy materials, you should follow the instructions for requesting such materials contained on the Notice.

If you receive more than one Notice, it means that your shares are registered differently and are held in more than one account. To ensure that all shares are voted, please either vote each account over the Internet or by telephone or sign and return by mail all proxy cards.

You are entitled to vote if you were a shareholder of record of Synovus Common Stock as of the close of business on February 13, 2014. Your shares can be voted at the meeting only if you are present or represented by a valid proxy.

If your shares are held in the name of a bank, broker or other holder of record, you will receive voting instructions from such holder of record. You must follow the voting instructions of the holder of record in order

for your shares to be voted. Telephone and Internet voting will also be offered to shareholders owning shares through certain banks, brokers and other holders of record. If your shares are not registered in your own name and you plan to vote your shares in person at the Annual Meeting, you should contact your broker or agent to obtain a legal proxy or broker’s proxy card and bring it to the Annual Meeting in order to vote at the Annual Meeting.

The Board has designated two individuals to serve as proxies to vote the shares represented by proxies at the Annual Meeting. If you properly submit a proxy but do not specify how you want your shares to be voted, your shares will be voted by the designated proxies in accordance with the Board’s recommendations as follows:

The designated proxies will vote in their discretion on any other matter that may properly come before the Annual Meeting. At this time, we are unaware of any matters, other than as set forth above, that may properly come before the Annual Meeting.

To be elected, each of the 14 director nominees named in this Proxy Statement must receive more votes cast “for” such nominee’s election than votes cast “against” such nominee’s election. If a nominee who currently is serving as a director does not receive the required vote for re-election, Georgia law provides that such director will continue to serve on the Board of Directors as a “holdover” director. However, pursuant to Synovus’ Corporate Governance Guidelines, each holdover

director has tendered an irrevocable resignation that would be effective upon the Board’s acceptance of such resignation. In that situation, our Corporate Governance and Nominating Committee would consider the resignation and make a recommendation to the Board of Directors about whether to accept or reject such resignation and publicly disclose its decision within 90 days following certification of the shareholder vote.

The option of one year, two years or three years that receives the highest number of votes cast by shareholders will be the frequency for the advisory vote on executive compensation that has been selected by shareholders. The Compensation Committee (which administers the Company’s executive compensation program) values the opinions expressed by shareholders in these votes and will continue to consider

the outcome of these votes in making its decisions on executive compensation. However, because this vote is advisory and not binding on the Board of Directors or Synovus in any way, the Board may decide that it is in the best interests of our shareholders and Synovus to hold an advisory vote on executive compensation more or less frequently than the option approved by our shareholders.

Under certain circumstances, including the election of directors and matters involving executive compensation, banks and brokers are prohibited from exercising discretionary authority for beneficial owners who have not provided voting instructions to the bank or broker. This is generally referred to as a “broker non-vote.” In these cases, for as long as a routine matter is also being voted on, and in cases where the shareholder does not vote on such routine matter, those shares will be counted for the purpose of determining if a quorum is present, but will not be included as votes cast with respect to those matters. Whether a bank or broker has authority to vote its shares on uninstructed matters

is determined by stock exchange rules. We expect that brokers will be allowed to exercise discretionary authority for beneficial owners who have not provided voting instructions only with respect to Proposal 4, Proposal 5 and Proposal 7 but not with respect to any of the other proposals to be voted on at the Annual Meeting. Broker non-votes will have no effect on any of these other proposals.

Abstentions will have the effect of votes AGAINST Proposal 4 and Proposal 5, but will have no effect on any of the other proposals to be considered at the Annual Meeting.

You can vote your shares by telephone by calling the toll-free telephone number (at no cost to you) shown on your proxy card. Telephone voting is available 24 hours a day, seven days a week, until 11:59 P.M., Eastern Time, on April 23, 2014. Easy-to-follow voice prompts allow you to vote your shares and confirm that your instructions have been

properly recorded. Our telephone voting procedures are designed to authenticate the shareholder by using individual control numbers. If you vote by telephone, you do NOT need to return your proxy card. If you vote by telephone, all of your shares will be voted as one vote per share.

You can also choose to vote on the Internet. The website for Internet voting is shown on your proxy card. Internet voting is available 24 hours a day, seven days a week, until 11:59 P.M., Eastern Time, on April 23, 2014. You will be given the opportunity to confirm that your instructions

have been properly recorded, and you can consent to view future proxy statements and annual reports on the Internet instead of receiving them in the mail. If you vote on the Internet, you do NOT need to return your proxy card.

If your shares are held in the name of a bank, broker or other holder of record, you will receive instructions from such holder of record that you must follow for your shares to be voted. Please follow their instructions carefully. Also, please note that if the holder of record of your shares is a broker, bank or other nominee and you wish to vote

in person at the Annual Meeting, you must request a legal proxy or broker’s proxy from your bank, broker or other nominee that holds your shares and present that proxy and proof of identification at the Annual Meeting.

We have a voting structure under which a holder of our Common Stock may be entitled to exercise ten votes per share for each of his or her shares that satisfy certain prescribed criteria and one vote per share for each of his or her shares that does not. As provided in Synovus’ Articles of Incorporation and bylaws, holders of Synovus Common Stock are entitled to ten votes on each matter submitted to a vote of shareholders for each share of Synovus Common Stock owned on February 13, 2014 which: (1) has had the same beneficial owner since April 24, 1986; (2) has been beneficially owned continuously by the same shareholder since February 13, 2010; (3) is held by the same beneficial owner to whom it was issued as a result of an acquisition of a company or business by Synovus where the resolutions adopted by Synovus’ Board of Directors approving the acquisition specifically grant ten votes per share; (4) is held by the same beneficial owner to whom it was issued by Synovus, or to whom it transferred by Synovus from treasury shares, and the resolutions adopted by Synovus’ Board of Directors approving such issuance and/or transfer specifically grant ten votes per share; (5) was acquired under any employee, officer and/or director benefit plan maintained for one or more employees, officers and/or directors of Synovus and/or its subsidiaries, and is held by the same owner for whom it was acquired under any such plan; (6) was acquired by reason of participation in a dividend reinvestment plan offered by Synovus and is held by the same owner who acquired it under such plan; or (7) is owned by a holder who, in addition to shares which are beneficially owned under the provisions of (1)-(6) above, is the owner of less than 1,139,063 shares of Synovus Common Stock (which amount is equal to 100,000 shares, as appropriately adjusted to reflect the change in shares of Synovus Common Stock by means of stock splits, stock dividends, any recapitalization or otherwise occurring since April 24, 1986). For purposes of determining voting power under these provisions, any share of Synovus Common Stock acquired pursuant to stock options shall be deemed to have been acquired on the date the option was granted, and any shares of Common Stock acquired as a direct result of a stock split, stock dividend or other type of share distribution will be deemed to have been acquired and held continuously from the date on which shares with regard to such dividend shares were issued were acquired. Under these voting provisions, a shareholder may hold some shares that qualify for 10-1 voting and some shares that do not. Holders of our Common Stock are entitled to one vote per share unless the holder can demonstrate that the shares meet the criteria above for being entitled to ten votes per share.

For purposes of the foregoing, a beneficial owner of a share of our Common Stock is defined to include a person or group of persons who, directly or indirectly, through any contract, arrangement, undertaking,

relationship or otherwise has or shares (1) voting power, which includes the power to vote, or to direct the voting of such share of Common Stock, (2) investment power, which includes the power to direct the sale or other disposition of such share of Common Stock, (3) the right to receive, retain or direct the distribution of the proceeds of any sale or other disposition of such share of Common Stock, or (4) the right to receive or direct the disposition of any distributions, including cash dividends, in respect of such share of Common Stock.

Shares of Synovus Common Stock are presumed to be entitled to only one vote per share unless this presumption is rebutted by providing evidence to the contrary to Synovus. Shareholders seeking to rebut this presumption should complete and execute the certification appearing on their proxy card. Synovus reserves the right to request additional documentation from you to confirm the voting power of your shares. Because certifications must be in writing, if you choose to vote by telephone, all of your shares will be voted as one vote per share. SHAREHOLDERS WHO DO NOT CERTIFY ON THEIR PROXIES SUBMITTED BY MAIL OR INTERNET THAT THEY ARE ENTITLED TO TEN VOTES PER SHARE OR WHO DO NOT PRESENT SUCH A CERTIFICATION IF THEY ARE VOTING IN PERSON AT THE ANNUAL MEETING WILL BE ENTITLED TO ONLY ONE VOTE PER SHARE.

For more detailed information on your voting rights, please refer to the Synovus 10-1 Voting Instructions and an accompanying voting instruction worksheet that are available on our website at www.synovus.com/2014annualmeeting.

Synovus Common Stock is registered with the Securities and Exchange Commission, or SEC, and is traded on the New York Stock Exchange, or NYSE. Accordingly, Synovus’ Common Stock is subject to the provisions of a NYSE rule which, in general, prohibits a company’s common stock and equity securities from being authorized or remaining authorized for trading on the NYSE if the company issues securities or takes other corporate action that would have the effect of nullifying, restricting or disparately reducing the voting rights of existing shareholders of the company. However, the rule contains a “grandfather” provision, under which Synovus’ ten vote provision falls, which, in general, permits grandfathered disparate voting rights plans to continue to operate as adopted. The number of votes that each shareholder will be entitled to exercise at the Annual Meeting will depend upon whether each share held by the shareholder meets the requirements which entitle one share of Synovus Common Stock to ten votes on each matter submitted to a vote of shareholders. Such determination will be made by Synovus based on information possessed by Synovus at the time of the Annual Meeting.

If you are a shareholder of record and vote by proxy, you may revoke that proxy at any time before it is voted at the Annual Meeting. You may do this by (1) signing another proxy card with a later date and returning it to us prior to the Annual Meeting, (2) voting again by telephone or on the Internet prior to 11:59 P.M., Eastern Time, on April 23, 2014, or (3) attending the Annual Meeting in person and casting a ballot.

If your Synovus shares are held by a bank, broker or other nominee, you must follow the instructions provided by the bank, broker or other nominee if you wish to change or revoke your vote.

The Annual Meeting will be held on Thursday, April 24, 2014 at 10:00 a.m. at the Columbus Georgia Convention and Trade Center, 801 Front Avenue, Columbus, Georgia. Directions to the Trade Center can be obtained from the Investor Relations page of Synovus’ website at www.synovus.com. If you are unable to attend the meeting, you can listen to it live and view the slide presentation over the Internet at www.synovus.com/2014annualmeeting.

Additionally, we will maintain copies of the slides and audio of the presentation for the Annual Meeting on our website for reference after the meeting. Information included on Synovus’ website, other than the Proxy Statement and form of proxy, is not a part of the proxy soliciting material.

The business affairs of Synovus are managed under the direction of the Board of Directors in accordance with the Georgia Business Corporation Code, as implemented by Synovus’ Articles of Incorporation and bylaws. The role of the Board of Directors is to effectively govern the affairs of Synovus for the benefit of its shareholders and other

constituencies. The Board strives to ensure the success and continuity of Synovus’ business through the election of qualified management. It is also responsible for ensuring that Synovus’ activities are conducted in a responsible and ethical manner. Synovus and its Board of Directors are committed to having sound corporate governance principles.

Since 2010, Synovus’ Board and management have concentrated significant efforts and resources into a review of Synovus’ overall corporate governance practices, focused on succession planning, responsiveness to the changing needs for financial institution boards in the current regulatory environment (including the governance changes for financial institutions under the The Dodd-Frank Wall Street Reform and Consumer Protection Act, which we refer to as the Dodd-Frank Act) and consideration of governance practices among similarly sized financial institutions. Over the past four years, the Board has adopted a series of changes to improve Synovus’ corporate governance structure and practices. These changes include:

The Board, under the leadership of the Corporate Governance and Nominating Committee, will continue to actively monitor and consider additional changes to our corporate governance practices in the future.

The NYSE listing standards provide that a director does not qualify as independent unless the Board of Directors affirmatively determines that the director has no material relationship with Synovus. The Board has established categorical standards of independence to assist it in determining director independence which conform to the independence requirements in the NYSE listing standards. The categorical standards of independence are incorporated within our Corporate Governance Guidelines, are attached to this Proxy Statement as Appendix A and are also available in the Corporate Governance Section of our website at www.synovus.com/governance.

The Board has affirmatively determined that a majority of its members are independent as defined by the listing standards of the NYSE and the categorical standards of independence set by the Board. Synovus’

Board has determined that, as of January 1, 2014, the following directors are independent: Catherine A. Allen, Stephen T. Butler, Elizabeth W. Camp, T. Michael Goodrich, V. Nathaniel Hansford, Jerry W. Nix, Joseph J. Prochaska, Jr., J. Neal Purcell, Melvin T. Stith, Barry L. Storey, Philip W. Tomlinson and James D. Yancey. Please see “Certain Relationships and Related Transactions” on page      of this Proxy Statement for a discussion of certain relationships between Synovus and its independent directors. These relationships have been considered by the Board in determining a director’s independence from Synovus under Synovus’ Corporate Governance Guidelines and the NYSE listing standards and were determined to be immaterial. Also, if elected to the Board at the Annual Meeting, the Board has affirmatively determined that Dr. Pastides will be independent.

The Board of Directors held 11 meetings in 2013. All directors attended at least 75% of Board and committee meetings held during their tenure during 2013. The average attendance by directors at the aggregate number of Board and committee meetings they were scheduled to

attend was 97%. Although Synovus has no formal policy with respect to Board members’ attendance at its annual meetings, it is customary for all Board members to attend the annual meetings. All of Synovus’ current directors attended Synovus’ 2013 Annual Meeting.

Synovus’ Board of Directors has five principal standing committees — an Audit Committee, a Corporate Governance and Nominating Committee, a Compensation Committee, a Risk Committee and an Executive Committee. Each committee has a written charter adopted by the Board of Directors that complies with the applicable listing standards of the NYSE pertaining to corporate governance. Copies of the committee charters are available in the Corporate Governance section of our

website at www.synovus.com/governance. The Board has determined that each member of the Audit, Corporate Governance and Nominating, Compensation and Risk Committees is an independent director as defined by the listing standards of the NYSE and our Corporate Governance Guidelines. The following table shows the membership of the various committees as of the date of this Proxy Statement.

Synovus’ Audit Committee held 10 meetings in 2013, two of which were joint meetings with the Risk Committee. The Audit Committee’s report is on page      of this Proxy Statement. The Board has determined that all four members of the Committee are independent and financially literate under the rules of the NYSE and that at least one member, J. Neal Purcell, is an “audit committee financial expert” as defined by the rules of the SEC. The primary functions of the Audit Committee include:

Synovus’ Corporate Governance and Nominating Committee held eight meetings in 2013. The primary functions of Synovus’ Corporate Governance and Nominating Committee include:

Synovus’ Compensation Committee held seven meetings in 2013. Its report is on page     of this Proxy Statement. The primary functions of the Compensation Committee include:

In addition, the Committee has the authority under its charter to retain outside advisors to assist the Committee in the performance of its duties. During 2013, the Committee retained the services of Meridian Compensation Partners, LLC, or Meridian, to:

The Committee evaluated whether the work provided by Meridian raised any conflict of interest. The Committee considered various factors, including the six factors mandated by SEC rules, and determined that no conflict of interest was raised by the work of Meridian described in this Proxy Statement.

Meridian was engaged directly by the Committee, although the Committee also directed that Meridian work with Synovus’ management to facilitate the Committee’s review of compensation practices and management’s recommendations. Synovus’ Chief Human Resources Officer and her staff develop executive compensation recommendations for the Committee’s consideration in conjunction with Synovus’ Chief Executive Officer and with the advice of Meridian.

Synovus’ Chief Human Resources Officer works with the Chairman of the Committee to establish the agenda for Committee meetings. Management also prepares background information for each committee meeting. Synovus’ Chief Human Resources Officer attends all committee meetings by invitation of the Committee, while Synovus’ Chief Executive Officer attends some committee meetings by invitation of the Committee. The Chief Executive Officer and the Chief Human Resources Officer do not have authority to vote on committee matters. Meridian attended all of the committee meetings held during 2013 at the request of the Committee. In addition, the Committee regularly meets in executive session with no members of management in attendance.

Synovus’ Risk Committee held eight meetings in 2013, two of which were joint meetings with the Audit Committee. The primary functions of Synovus’ Risk Committee include:

Synovus’ Executive Committee held two meetings in 2013. During the intervals between meetings of Synovus’ Board of Directors, the Executive Committee possesses and may exercise any and all of the powers of Synovus’ Board of Directors in the management and direction of the business and affairs of Synovus with respect to which specific direction has not been previously given by the Board of

Directors unless Board action is required by Synovus’ governing documents, law or rule. The Executive Committee is comprised of the chairpersons of the principal standing Committees of the Synovus Board and Synovus Bank Board, the Chief Executive Officer, the Chairman of the Board (if different from the Chief Executive Officer) and the Lead Director.

Under Synovus’ Corporate Governance Guidelines, the Board is charged with providing oversight of Synovus’ risk management processes. The Risk Committee fulfills the overarching oversight role for overseeing the enterprise risk management and compliance processes, including approval of risk tolerance levels and risk policies and limits, monitoring key and emerging risks and reviewing risk assessments. In carrying out its responsibilities, the Risk Committee works closely with Synovus’ Chief Risk Officer and other members of Synovus’ enterprise risk management and compliance teams. The Risk Committee meets periodically with the Chief Risk Officer and other members of management and receives a comprehensive report on enterprise risk management and compliance matters, including management’s assessment of risk exposures (including risks related to liquidity, credit, operations, regulatory compliance, and future growth, among others) and the processes in place to monitor and control such exposures. The Risk Committee also receives updates between meetings from the

Chief Risk Officer, the Chief Executive Officer, the Chief Financial Officer, the Chief Information Security Officer and the Senior Director of Compliance and other members of management relating to risk oversight and compliance matters. The Risk Committee provides a report on risk management to the full Board on at least a quarterly basis. In addition, at least annually, the Chief Risk Officer and members of the enterprise risk management and compliance team make a presentation on enterprise risk management and compliance to the full Board.

In addition, the Risk Committee coordinates with the Audit Committee for the review of financial statement and related risks and other areas of joint responsibility, with the Compensation Committee for review of compensation-related risks and with the Corporate Governance and Nominating Committee on corporate governance-related risks. For a discussion of the Compensation Committee’s review of Synovus’ senior

executive officer compensation plans and employee incentive compensation plans and the risks associated with these plans, see “Compensation Committee Report — Incentive Compensation Plan Risk Assessment” on page     of this Proxy Statement.

The Board’s role in risk oversight is an integral part of Synovus’ overall enterprise risk management framework. For a more detailed description of Synovus’ enterprise risk management framework, see “Part I — Item 1. Business — Enterprise Risk Management” in Synovus’ 2013 Annual Report.

Synovus’ Corporate Governance Guidelines contain Board membership criteria considered by the Corporate Governance and Nominating Committee in recommending nominees for a position on Synovus’ Board. The Committee believes that, at a minimum, a director candidate must possess personal and professional integrity, sound judgment and forthrightness. A director candidate must also have sufficient time and energy to devote to the affairs of Synovus, be free from conflicts of interest with Synovus, must not have reached the retirement age for Synovus directors and be willing to make, and financially capable of making, the required investment in Synovus’ stock pursuant to Synovus’ Director Stock Ownership Guidelines. The Committee also considers the following criteria when reviewing director candidates and existing directors:

The Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. In addition to the criteria set forth above, the Committee considers how the skills and attributes of each individual candidate or incumbent director work together to create a board that is collegial, engaged and effective in performing its duties. Although the Board does not have a formal policy on diversity, the Board and the Committee believe that the background and qualifications of the directors, considered as a group, should provide a significant mix of experience, knowledge and abilities that will contribute to Board diversity and allow the Board to effectively fulfill its responsibilities. For a discussion of the specific backgrounds and qualifications of our director nominees, see “Proposals to be Voted on: Proposal 1 — Election of 14 Directors — Nominees for Election as Director” beginning on page     of this Proxy Statement.

The Corporate Governance and Nominating Committee has two primary methods for identifying director candidates (other than those proposed by Synovus’ shareholders, as discussed below). First, on a periodic basis, the Committee solicits ideas for possible candidates from a number of sources including members of the Board, Synovus executives and individuals personally known to the members of the Board. Second, the Committee is authorized under its charter to retain at Synovus’ expense one or more search firms to identify candidates (and to approve such firms’ fees and other retention terms).

The Committee will consider all director candidates identified through the processes described above, and will evaluate each of them, including incumbents, based on the same criteria. The director candidates are evaluated at regular or special meetings of the Committee and may be considered at any point during the year. If based on the Committee’s initial evaluation a director candidate continues to be of interest to the Committee, the Chair of the Committee will interview the candidate and communicate his evaluation to the other Committee members and executive management. Additional interviews are conducted, if necessary, and ultimately the Committee will meet to finalize its list of recommended candidates for the Board’s consideration.

The Corporate Governance and Nominating Committee will consider candidates for nomination as a director submitted by shareholders. Although the Committee does not have a separate policy that addresses the consideration of director candidates recommended by shareholders, the Board does not believe that such a separate policy is necessary as Synovus’ bylaws permit shareholders to nominate candidates and as one of the duties set forth in the Corporate Governance and Nominating

Committee charter is to review and consider director candidates submitted by shareholders. The Committee will evaluate individuals recommended by shareholders for nomination as directors according to the criteria discussed above and in accordance with Synovus’ bylaws and the procedures described under “Shareholder Proposals and Nominations” on page     of this Proxy Statement.

In accordance with Synovus’ bylaws, our Board of Directors elects our Chief Executive Officer and our Chairman, and each of these positions may be held by the same person or may be held by two persons. Under our Corporate Governance Guidelines, the Board does not have a policy, one way or the other, on whether the role of the Chairman and Chief Executive Officer should be separate and, if it is to be separate, whether the Chairman should be selected from the non-employee directors or be an employee. However, our Corporate Governance Guidelines require that, if the Chairman of the Board is not an independent director, the Corporate Governance and Nominating Committee shall nominate, and a majority of the independent directors shall elect, a Lead Director. Under its charter, the Corporate Governance and Nominating Committee periodically reviews and recommends to the Board the leadership structure of the Board and, if necessary, nominates the Lead Director candidate from the independent directors. Currently, one individual serves as both our Chief Executive Officer and Chairman and, as a result, Synovus also has a Lead Director. The Board currently believes that the combination of these two roles provides more consistent communication and coordination throughout the organization, which results in a more effective and efficient implementation of corporate strategy and is important in unifying Synovus’ strategy behind a single vision.

The Chairman of the Board is responsible for chairing Board meetings and meetings of shareholders, setting the agendas for Board meetings in consultation with the Lead Director and providing information to the Board members in advance of meetings and between meetings. Pursuant to Synovus’ Corporate Governance Guidelines, the duties of the Lead Director include the following:

After careful consideration, the Corporate Governance and Nominating Committee has determined that Synovus’ current Board structure is the most appropriate leadership structure for Synovus and its shareholders at this time.

Synovus’ Board provides a process for shareholders and other interested parties to communicate with one or more members of the Board, including the Lead Director, or the non-management or independent directors as a group. Shareholders and other interested parties may communicate with the Board as follows:

These procedures are also available in the Corporate Governance section of our website at www.synovus.com/governance. Synovus’ process for handling shareholder and other communications to the Board has been approved by Synovus’ independent directors.

Synovus has adopted Corporate Governance Guidelines which are regularly reviewed by the Corporate Governance and Nominating Committee. We have also adopted a Code of Business Conduct and Ethics which is applicable to all directors, officers and employees. In addition, we maintain procedures for the confidential, anonymous submission of any complaints or concerns about Synovus, including complaints regarding accounting, internal accounting controls or auditing matters. Shareholders may access Synovus’ Corporate Governance

Guidelines, Code of Business Conduct and Ethics, each committee’s current charter, procedures for shareholders and other interested parties to communicate with the Lead Director or with the non-management or independent directors individually or as a group and procedures for reporting complaints and concerns about Synovus, including complaints concerning accounting, internal accounting controls and auditing matters, in the Corporate Governance section of our website at www.synovus.com/governance.

As reflected in the “Fees Earned or Paid in Cash” column of the Director Compensation Table below, during 2013, non-management directors of Synovus received an annual cash retainer of $40,000, with

Directors who are employees of Synovus do not receive any additional compensation for their service on the Board.

By paying directors an annual retainer, Synovus compensates each director for his or her role and judgment as an advisor to Synovus, rather than for his or her attendance or effort at individual meetings. In so doing, directors with added responsibility are recognized with higher cash compensation. For example, members of the Audit Committee receive a higher cash retainer based upon the enhanced duties, time commitment and responsibilities of service on that committee. The

Board believes that this additional cash compensation is appropriate. In

addition, directors may from time to time receive compensation for serving on advisory committees of the Synovus Board.

Recognizing Synovus’ corporate governance initiatives and efforts to pursue and consider additional independent directors to be added to the Board each year, the Board changed the pay practices in 2011 to provide that the members of the Board shall be compensated each April for their service on the Board from the date of the annual meeting to the following year’s annual meeting. As such, the Board was compensated in 2013 for the full year of service for the period from April 25, 2013 through April 24, 2014.

Directors may elect to defer all or a portion of their cash compensation under the Synovus Directors’ Deferred Compensation Plan. The Directors’ Deferred Compensation Plan does not provide directors with an “above market” rate of return. Instead, the deferred amounts mirror the return of one or more investment funds selected by the director. In so doing, the plan is designed to allow directors to defer the income taxation of a portion of their compensation and to receive an investment return on those deferred amounts. All deferred fees are payable only in cash. Four directors (Ms. Camp and Messrs. Goodrich, Hansford and Storey) elected to defer their 2013 cash compensation under this plan.

During 2013, non-management directors also received awards of restricted stock units under the Synovus 2013 Omnibus Plan. On June 27, 2013, the Board approved grants of $20,000 (fair market value), or 6,897 restricted stock units, to the non-management members of the Board elected on April 25, 2013 to serve as directors for a term ending on April 24, 2014. The director restricted stock units are fully vested and transferable upon the satisfaction of the following two conditions: (1) the earlier to occur of (x) the completion of three years of service and (y) the date the holder reaches age 72; and (2) repayment by Synovus of all or a portion of its obligations under TARP. These restricted stock unit awards are designed to create equity ownership and to focus directors on the long-term performance of Synovus.

Synovus’ 2011 Director Stock Purchase Plan is a non-qualified, contributory stock purchase plan pursuant to which qualifying Synovus directors can purchase, with the assistance of contributions from Synovus, presently issued and outstanding shares of Synovus stock. Under the terms of the Director Stock Purchase Plan, qualifying directors can elect to contribute up to $5,000 per calendar quarter to make purchases of Synovus stock, and Synovus contributes an additional amount (equal to 15% of the directors’ cash contributions in

2013). Participants in the Director Stock Purchase Plan are fully vested in all shares of Synovus stock purchased for their benefit under the Plan and may request that the shares purchased under the Plan be released to them at any time. Synovus’ contributions under this Plan are included in the “All Other Compensation” column of the Director Compensation Table below. Synovus’ contributions under the Director Stock Purchase Plan provide directors the opportunity to buy and maintain an equity interest in Synovus and to share in the capital appreciation of Synovus.

The restricted stock unit awards to directors and Synovus’ contributions under the Director Stock Purchase Plan also assist and facilitate directors’ fulfillment of their stock ownership requirements. Synovus’ Corporate Governance Guidelines require all directors to accumulate over time shares of Synovus stock equal in value to at least three times the value of their annual retainer. Directors have five years to attain this level of total stock ownership but must attain a share ownership threshold of one times the amount of the director’s annual retainer within three years. These stock ownership guidelines are designed to align the interests of Synovus’ directors to that of Synovus’ shareholders and the long-term performance of Synovus. All of Synovus’ directors were in compliance with the guidelines as of December 31, 2013.

Pursuant to Synovus’ bylaws, the Board shall consist of not less than 8 nor more than 25 directors with such number to be set either by the Board or shareholders representing at least 66 2/3% of the votes entitled to be cast by the holders of all of Synovus’ issued and outstanding shares. Currently, the size of the Board is set at 14 members. Proxies cannot be voted at the Annual Meeting for a greater number of persons than the 14 nominees named in this Proxy Statement.

Two of our current directors, J. Neal Purcell and James D. Yancey, have reached the mandatory retirement age for directors established under our Corporate Governance Guidelines and will not stand for re-election at the Annual Meeting. We thank both of these directors for their long and outstanding service to the Board and to Synovus.

The 14 nominees for director named in this Proxy Statement were selected by the Corporate Governance and Nominating Committee based upon a review of the nominees and consideration of the director qualifications described under “Corporate Governance and Board Matters — Consideration of Director Candidates — Director Qualifications” on page      of this Proxy Statement. In addition to the specific criteria for director nomination, the Corporate Governance and Nominating Committee assesses whether a candidate possesses the integrity, judgment, knowledge, experience, skills and expertise that are likely to enhance the Board’s ability to manage and direct the affairs and business of Synovus. With respect to the nomination of continuing directors for re-election, the Corporate Governance and Nominating Committee also considers the individual’s contributions to the Board and its committees. Twelve of the 14 nominees currently serve as a director. The nominees for director include seven current and former chief executive officers, at least 11 persons who could be recognized as “audit committee financial experts, three current or former deans of national universities, and a former partner of a global auditing firm. The nominees collectively have over 150 years of experience in banking and financial services as well as significant experience in insurance, investment management, commercial real estate and accounting. The nominees also bring extensive board and committee experience.

In addition to the overall composition of the Board, the Corporate Governance and Nominating Committee also considered the nominees’ individual roles in (1) oversight of our enterprise risk management

initiatives, (2) relationships with the numerous regulatory agencies that monitor Synovus’ operations, (3) oversight and support of our asset disposition and expense reduction initiatives, (4) assistance with the strategic plan of the Company and (5) managing succession planning. In addition to fulfilling the above criteria, 11 of the 14 nominees for election named below are considered independent under the NYSE rules and Synovus’ Director Independence Standards. Each nominee also brings a strong and unique background and set of skills to the Board, giving the Board as a whole competence and experience in a wide variety of areas, including corporate governance and board service, executive management, risk management and oversight, corporate strategy, commercial real estate, troubled asset work-out and disposition situations, and ancillary financial services businesses. Each member of the Board has demonstrated leadership through his or her work on the boards of a variety of public, private and non-profit organizations and is familiar with board processes and corporate governance. We believe the atmosphere of our Board is collegial and that all Board members are engaged in their responsibilities. For additional information about our director independence requirements, consideration of director candidates, leadership structure of our Board and other corporate governance matters, see “Corporate Governance and Board Matters” beginning on page      of this Proxy Statement.

The following table sets forth information regarding the 14 nominees for election to the Board.

Synovus believes that our compensation policies and procedures for our named executive officers are competitive, are focused on pay for performance principles and are strongly aligned with the long-term interests of our shareholders. Synovus also believes that both we and our shareholders benefit from responsive corporate governance policies and constructive and consistent dialogue. The proposal described below, commonly known as a “Say on Pay” proposal, gives you, as a shareholder, the opportunity to endorse or not endorse the compensation for our named executive officers by voting to approve or not approve, on an advisory basis, such compensation as described in this Proxy Statement.

As discussed under “Executive Compensation — Compensation Discussion and Analysis” beginning on page      of this Proxy Statement,

Synovus’ compensation program for its executive officers is performance-oriented and designed to support our strategic goals. 2013 was a critical year for Synovus and our executive compensation program. We continued to improve our performance and passed a critical milestone with the redemption of our TARP obligations. With the TARP redemption in July, we are now no longer subject to the related restrictions on the structure of our executive compensation program. While our 2013 executive compensation remained significantly impacted by the TARP restrictions, we began the process of returning to a program in line with our pay for performance philosophy.

The compensation of executives in 2013 reflects Synovus’ performance and the requirements of the TARP program during the TARP period, as well as the beginning of our transition to a program more in line with our pay for performance philosophy. For example:

Base Salaries

Short-Term Incentives

Long-Term Incentives

We believe that the compensation delivered to each named executive officer in 2013 was fair and reasonable. Although compensation increased in 2013 as we began the transition to our new post-TARP program, our executive compensation remains below market.

The Board of Directors unanimously recommends that you vote “FOR” the advisory vote on the compensation of the named executive officers as determined by the Compensation Committee, as described in the Compensation Discussion and Analysis and the tabular disclosure regarding named executive officer compensation (together with the accompanying narrative disclosure) in this Proxy Statement.

In addition to the advisory approval of our executive compensation program, we are also seeking a non-binding determination from our shareholders as to the frequency with which shareholders would have an opportunity to provide an advisory approval of our executive compensation program. We are providing shareholders the option of selecting a frequency of one, two or three years, or abstaining. For the reasons described below, we recommend that our shareholders select a frequency of one year, or an annual vote.

As described in Proposal 2 above, our shareholders are being provided the opportunity to cast an advisory vote on Synovus’ executive compensation program. The advisory vote on executive compensation described in Proposal 2 above is referred to as a “say-on-pay vote.”

This Proposal 3 affords shareholders the opportunity to cast an advisory vote on how often Synovus should include a say-on-pay vote in its proxy materials for future annual shareholders meetings (or any special shareholders meeting for which Synovus must include executive compensation information in the proxy statement for that meeting). Under this Proposal 3, shareholders may vote to have the say-on-pay vote every year, every two years or every three years.

We provided our shareholders with the opportunity to cast a say-on-pay vote every year from 2009 through 2013. An annual advisory vote on executive compensation will allow our shareholders to provide us with their direct input on our compensation philosophy, policies and

practices as disclosed in the proxy statement every year. An annual vote better corresponds with the presentation of compensation information in this Proxy Statement. We, therefore, request that our shareholders select “EVERY YEAR” when voting on the frequency of advisory votes on executive compensation.

We have included this proposal in our Proxy Statement pursuant to the requirements of Section 14A of the Securities Exchange Act of 1934. The option of one year, two years or three years that receives the highest number of votes cast by shareholders will be the frequency for the advisory vote on executive compensation that has been selected by shareholders. The Compensation Committee (which administers the Company’s executive compensation program) values the opinions expressed by shareholders in these votes and will continue to consider the outcome of these votes in making its decisions on executive compensation. However, because this vote is advisory and not binding on our Board or Synovus in any way, the Board may decide that it is in the best interests of our shareholders and Synovus to hold an advisory vote on executive compensation more or less frequently than the option approved by our shareholders.

The Board of Directors unanimously recommends that you vote “EVERY YEAR” to hold an advisory vote on executive compensation (as opposed to every two years or every three years).

Background

Synovus’ Amended and Restated Articles of Incorporation, or the Articles, currently authorize 1,200,000,000 shares of Common Stock. As of February 13, 2014, 972,411,548 shares of Common Stock were issued and outstanding, 81,840,038 shares of Common Stock were subject to awards, or reserved for future awards, under Synovus’ stock compensation plans, and 15,510,737 shares of Common Stock were reserved for issuance in connection with the conversion of outstanding warrants issued in December 2008 to the United States Department of the Treasury as part of its $968 million investment in our preferred stock. Accordingly, we have only 130,237,677 shares of Common Stock available for future issuance.

Proposed Amendment

On February 19, 2014, the Board of Directors unanimously approved, subject to shareholder approval, an amendment to Article 4 of the Articles to increase the number of authorized shares of Common Stock, $1.00 par value, from 1,200,000,000 to 2,400,000,000 shares (or from 171,428,571 shares to 342,857,142 shares if Proposal 5 is approved

and the Reverse Stock Split is implemented) (the “Amendment”). The form of the Articles of Amendment to effect the increase in the number of authorized shares of our Common Stock is set forth in Appendix B to this Proxy Statement.

If the Amendment is approved, it will become effective upon the filing of an amendment to the Articles with the Secretary of State of the State of Georgia, which Synovus expects to occur following shareholder approval of the proposal described herein. If the proposal is not approved by our shareholders, no amendment with respect to an increase in the number of authorized shares of Common Stock will be filed with the Secretary of State of the State of Georgia and the proposal will not be implemented.

We are not proposing to increase the number of shares of preferred stock. We have designated 2,500 shares as Series B Participating Cumulative Preferred Stock, none of which shares are issued and outstanding, and 5,200,000 shares of preferred stock as Series C, all of which were issued in a public offering in July 2013. We believe that the over 94,000,000 shares of remaining preferred stock will be adequate for the foreseeable future.

Purpose and Effect of the Amendment

The principal purpose of the Amendment is to provide us with additional financial flexibility to issue Common Stock for purposes which may be identified in the future, including, without limitation, making acquisitions through the use of Common Stock, distributing Common Stock to shareholders pursuant to stock splits and/or stock dividends, adopting additional equity incentive plans or reserving additional shares for issuance under such plans, raising additional equity capital, and effecting other general corporate purposes. As of the date of the filing of this Proxy Statement, with the exception of shares reserved for issuance under Synovus’ stock compensation plans and conversion of outstanding warrants, Synovus has no existing plans, arrangements or understandings to issue shares of Common Stock that will be available if shareholders approve this Amendment and it becomes effective. The availability of additional shares of Common Stock is particularly important if the Board of Directors needs to undertake any of the foregoing actions on an expedited basis. An increase in the number of authorized shares of Common Stock would enable the Board of Directors to avoid the time (and expense) of seeking shareholder approval in connection with any such contemplated action and would enhance our ability to respond promptly to opportunities for acquisitions, mergers, stock splits or additional financings.

If the Amendment is approved by the shareholders, upon the effective date of the Amendment, Synovus would have approximately 1,330,237,677 shares of Common Stock (or 190,033,954 shares if Proposal 5 is approved and the Reverse Stock Split is implemented) available for future issuance after taking into account the number of shares currently outstanding and reserved for other purposes. If the Amendment is not approved by our shareholders, the number of authorized shares of Common Stock will remain at 1,200,000,000 (or 171,428,571 shares if Proposal 5 is approved and the Reverse Stock Split is implemented) and Synovus would only have approximately 130,237,677 shares of Common Stock (or 18,605,382 shares if Proposal 5 is approved and the Reverse Stock Split is implemented) available for future issuance, after taking into account the shares currently outstanding and reserved for other purposes.

If the Amendment is approved by our shareholders, the Board of Directors does not intend to solicit further shareholder approval prior to the issuance of any additional shares of Common Stock, except as may be required by applicable law or the rules of any stock exchange upon which our securities may be listed.

The Board of Directors believes that the Amendment is in the best interests of Synovus and our shareholders and is consistent with sound corporate governance principles.

Dilution

Adoption of the Amendment and the issuance of any Common Stock would have no effect on the rights of the holders of currently outstanding Common Stock. The additional shares of Common Stock to be authorized by adoption of the Amendment would have rights identical to the currently outstanding Common Stock.

Under the Articles, our shareholders do not have preemptive rights to subscribe to additional securities which may be issued by Synovus, which means that current shareholders do not have a prior right to purchase any new issue of capital stock of Synovus in order to maintain their proportional ownership of such shares. In addition, to the extent that additional shares are actually issued, any such issuance would have the effect of diluting the earnings per share and book value per share of outstanding shares of Common Stock.

Anti-Takeover Effects

The proposed Amendment to increase the number of authorized shares of Common Stock could, under certain circumstances, have an anti-takeover effect, although this is not the intent of our Board of Directors. The increase in the authorized number of shares of Common Stock and the subsequent issuance of such shares could have the effect of delaying or preventing a change in control of Synovus without further action by the shareholders. This proposal is not being submitted as a result of or in response to any threatened takeover or attempt to obtain control of Synovus by means of a business combination, tender offer, solicitation in opposition to management or otherwise by any person, and the Board of Directors has no knowledge of any current effort to obtain control of Synovus or to accumulate large amounts of shares of Common Stock. The Board of Directors represents that it will not, without prior shareholder approval, issue Common Stock for any defensive or anti-takeover purpose or for the purpose of implementing any shareholder rights plan (other than a “tax preservation” shareholder rights plan to protect the use of Synovus’ net operating losses).

Potential Impact If Amendment is Not Adopted

If the Amendment is not adopted by our shareholders and we are unable to increase our number of authorized shares of Common Stock, we will only have approximately 130,237,677 million shares of Common Stock (or 18,605,382 shares if Proposal 5 is approved and the Reverse Stock Split is implemented) available for future issuance, after taking into account the shares currently outstanding and reserved for other purposes. This limited number of available shares could restrict our ability to make acquisitions through the use of Common Stock, or securities convertible into Common Stock or to raise capital, including taking advantage of financing techniques that receive favorable treatment from regulatory agencies and credit rating agencies, if we determine that additional capital is in the best interests of Synovus and our shareholders. Without sufficient shares of Common Stock to issue in financing transactions and acquisitions with little or no delay, we may be unable to take full advantage of changing market conditions that will best position Synovus for future growth.

The Board of Directors unanimously recommends that you vote “FOR” the approval of the amendment to Synovus’ Amended and Restated Articles of Incorporation to increase the number of shares of Synovus’ Common Stock we are authorized to issue.

General

Synovus’ Board of Directors has approved an amendment to the Articles to effect a Reverse Stock Split, subject to approval of the amendment by shareholders, and is hereby soliciting shareholder approval for the amendment. If approved by Synovus’ shareholders, the Reverse Stock Split would permit (but not require) the Board of Directors to effect a reverse stock split of the Common Stock at any time prior to December 31, 2014, by a 1-for-7 ratio. As a result of the Reverse Stock Split, each 7 shares of Common Stock will be combined into one share of Common Stock, and the number of shares of Common Stock issued and outstanding will therefore be reduced.

Concurrently with the Reverse Stock Split, Synovus would also file an amendment to the Articles to proportionately reduce the number of authorized shares of Common Stock from 2,400,000,000 shares to 342,857,142 shares if Proposal 4 is also approved, or from 1,200,000,000 shares to 171,428,571 shares if Proposal 4 is not also approved. The form of the Articles of Amendment to effect the Reverse Stock Split and the related proportional decrease in the number of authorized shares of our Common Stock is set forth in Appendix C to this Proxy Statement. If for any reason the Board of Directors determines not to implement the Reverse Stock Split, it would also not

implement the amendment to the Articles to reduce proportionately the number of authorized shares of Common Stock.

To avoid the existence of fractional shares of our Common Stock, shareholders of record who would otherwise hold fractional shares of our Common Stock as a result of the Reverse Stock Split will be entitled to receive a cash payment (without interest and subject to applicable withholding taxes) in lieu of such fractional shares from Synovus’ transfer agent. The total amount of cash that will be paid to holders of fractional shares following the Reverse Stock Split will be an amount equal to the net proceeds attributable to the sale of such fractional shares following the aggregation and sale by our transfer agent of all fractional interests otherwise issuable. Holders of fractional interests as a result of the Reverse Stock Split will be paid such proceeds on a pro rata basis, according to the fractional interests that they owned.

The Reverse Stock Split, if approved by Synovus’ shareholders and formally declared by our Board, would become effective upon the filing of Articles of Amendment to the Articles with the Secretary of State of the State of Georgia. The exact timing of the filing of the Articles of Amendment that will effect the Reverse Stock Split will be determined by the Board of Directors based on its evaluation as to when such action will be the most advantageous to Synovus and the shareholders.

Purpose of Reverse Stock Split

The Board of Directors is submitting the Reverse Stock Split to shareholders for approval with the primary intent of increasing the market price of the Common Stock to trade at approximately 7 times the price per share at which it trades prior to the effectiveness of the Reverse Stock Split. We believe that the anticipated increase in the market price per share resulting from the Reverse Stock Split will help make our Common Stock more attractive to a broader range of investors for the following reasons:

For these reasons, we believe that the Reverse Stock Split may make the Common Stock a more attractive investment for certain investors, which we in turn believe may enhance the liquidity of the holders of the Common Stock.

Although the Reverse Stock Split is being proposed for the purpose of increasing the market price of Synovus’ Common Stock, we cannot assure you that such price increase can be achieved or maintained. A number of factors will influence the future trading price of the Common

Stock, many of which are not within Synovus’ control. As a result, there can be no assurance that the Reverse Stock Split, if completed, will result in the intended benefits described above, including that the market price of the Common Stock will increase following the Reverse Stock Split (either at all or in proportion to the reduction in the number of shares of Common Stock outstanding before the Reverse Stock Split), or that the market price of the Common Stock will not decrease in the future. Accordingly, the total market capitalization of the Common Stock after the Reverse Stock Split may be lower than the total market capitalization before the Reverse Stock Split.

Beneficial Holders of Common Stock

Upon the implementation of the Reverse Stock Split, we intend to treat shares of Common Stock held by shareholders through a bank, broker, custodian or other nominee in the same manner as registered shareholders whose shares are registered in their names. Banks, brokers, custodians or other nominees will be instructed to effect the Reverse Stock Split for their beneficial holders holding Common Stock in street name. However, these banks, brokers, custodians or other nominees may have different procedures than registered shareholders for processing the Reverse Stock Split. Shareholders who hold shares of Common Stock with a bank, broker, custodian or other nominee and who have any questions in this regard are encouraged to contact their banks, brokers, custodians or other nominees.

Registered “Book-Entry” Holders of Common Stock

Certain of our registered holders of Common Stock may hold some or all of their shares electronically in book-entry form with our transfer agent. These shareholders do not have stock certificates evidencing their ownership of the Common Stock. They are, however, provided with a statement reflecting the number of shares registered in their accounts. Shareholders who hold shares electronically in book-entry form with the transfer agent will not need to take action (the exchange will be automatic) to receive shares of post-Reverse Stock Split Common Stock.

Holders of Certificated Shares

Shareholders holding shares of Common Stock in certificated form will be sent a transmittal letter by the transfer agent after the Reverse Stock Split is consummated. The letter of transmittal will contain instructions on how a shareholder should surrender his, her or its certificate(s) representing shares of Common Stock (the “Old Shares”) to the transfer agent in exchange for a book-entry with Synovus’ transfer agent representing the appropriate number of shares of post-Reverse Stock Split Common Stock (the “New Shares”). No New Shares will be issued to a shareholder until such shareholder has surrendered all Old Shares, together with a properly completed and executed letter of transmittal, to the transfer agent. No shareholder will be required to pay a transfer or other fee to exchange Old Shares. Shareholders will then receive confirmation from the transfer agent that a book-entry has been made for the New Shares, representing the number of shares of Common Stock to which such shareholder is entitled as a result of the Reverse Stock Split. Until surrendered, we will deem outstanding Old Shares held by shareholders to be cancelled and only to represent the number of shares of post-Reverse Stock Split Common Stock to which these shareholders are entitled. Any Old Shares submitted for exchange, whether because of a sale, transfer or other disposition of stock, will automatically be exchanged for New Shares. If Old Shares contain a restrictive legend on the back, the New Shares will be restricted in the same manner. Upon request to the transfer agent, shareholders may elect for the transfer agent to deliver physical stock certificates representing the New Shares in lieu of the book-entry described above.

SHAREHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY STOCK CERTIFICATE(S) UNTIL REQUESTED TO DO SO.

Fractional Shares

We do not intend to issue fractional shares of the Common Stock in connection with the Reverse Stock Split. Instead, shareholders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will receive a cash payment in lieu of any fractional interests as a result of the Reverse Stock Split. The total amount of cash that will be paid to holders of fractional shares following the Reverse Stock Split will be an amount equal to the net proceeds attributable to the sale of such fractional shares following the aggregation and sale by our transfer agent of all fractional interests otherwise issuable. Specifically, the transfer agent will act on account of the holders of those entitled to receive fractional shares and will accumulate such fractional shares, sell the shares, and distribute the cash proceeds directly to the shareholders entitled to receive the fractional shares.

Accounting Matters

The proposed amendments to the Articles will not affect the par value of the Common Stock per share, which will each continue to have $1.00 par value per share. As a result, the total stated capital attributable to Common Stock and the additional paid-in capital account on our balance sheet will not change due to the Reverse Stock Split. Reported per share net income or loss will be higher because there will be fewer shares of Common Stock outstanding.

Certain Federal Income Tax Consequences of the Reverse Stock Split

The following summary describes certain material U.S. federal income tax consequences of the Reverse Stock Split to holders of the Common Stock.

This summary addresses the tax consequences only to a beneficial owner of the Common Stock. This summary does not address all of the tax consequences that may be relevant to any particular investor, including tax considerations that arise from rules of general application to all taxpayers or to certain classes of taxpayers or that are generally assumed to be known by investors. This summary also does not address the tax consequences to (1) persons that may be subject to special treatment under U.S. federal income tax law, such as banks, insurance companies, thrift institutions, regulated investment companies, real estate investment trusts, tax-exempt organizations, U.S. expatriates, persons subject to the alternative minimum tax, traders in securities that elect to mark to market and dealers in securities or currencies, (2) persons that hold the Common Stock as part of a position in a “straddle” or as part of a “hedging,” “conversion” or other integrated investment transaction for federal income tax purposes, or (3) persons that do not hold the Common Stock as “capital assets” (generally, property held for investment).

This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, Treasury regulations, administrative rulings and judicial authority, all as in effect as of the date hereof. Subsequent developments in U.S. federal income tax law, including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the U.S. federal income tax consequences of the Reverse Stock Split.

CIRCULAR 230 NOTICE

ANY FEDERAL TAX ADVICE CONTAINED IN THIS MEMORANDUM, ANY SUPPLEMENTS THERETO, OR IN ANY ATTACHMENTS TO SUCH MEMORANDUM OR SUPPLEMENTS IS NOT INTENDED OR WRITTEN TO BE USED, AND IT CANNOT BE USED, BY ANY TAXPAYER FOR THE PURPOSE OF AVOIDING ANY PENALTY THAT MAY BE IMPOSED UNDER THE CODE. PLEASE BE ADVISED THAT THIS ADVICE WAS WRITTEN TO SUPPORT THE PROMOTION OR MARKETING OF THE TRANSACTIONS OR MATTERS ADDRESSED HEREIN BY THE WRITTEN ADVICE, AND THE TAXPAYER SHOULD SEEK ADVICE FROM AN INDEPENDENT TAX ADVISOR BASED ON THE TAXPAYER’S PARTICULAR CIRCUMSTANCES.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL, AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT.

If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of the Common Stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships that hold the Common Stock, and partners in such partnerships, should consult their own tax advisors regarding the U.S. federal income tax consequences of the Reverse Stock Split.

Tax Consequences of the Reverse Stock Split Generally

It is expected that the Reverse Stock Split will be treated as a recapitalization for U.S. federal income tax purposes. Accordingly, except as provided in the following paragraph, (i) no gain or loss is expected to be recognized upon the Reverse Stock Split, (ii) the aggregate tax basis in the Common Stock received pursuant to the Reverse Stock Split should equal the aggregate tax basis in the Common Stock surrendered, and (iii) the holding period for the Common Stock received should include the holding period for the Common Stock surrendered.

Cash received by a beneficial owner of Common Stock in lieu of fractional shares generally will be treated as if the beneficial owner received the fractional shares in the Reverse Stock Split and then received the cash in redemption of the fractional shares. The beneficial owner generally should recognize capital gain or loss equal to the difference between the amount of the cash received in lieu of fractional shares and the portion of the beneficial owner’s tax basis allocable to the fractional shares.

Dissenters’ Rights

Under Georgia law, shareholders are not entitled to dissenters’ rights with respect to the Reverse Stock Split.

Effect of Proposal

If the Reverse Stock Split proposal is approved, there will be no impact on shareholders until Synovus’ Board of Directors determines to implement the Reverse Stock Split. The Reverse Stock Split, once implemented, would affect all of Synovus’ shareholders and would not affect any shareholder’s percentage ownership interests or proportionate voting power, except as described below under

“Fractional Shares.” The principal effects of the Reverse Stock Split would be that:

Although the number of outstanding shares of Common Stock would decrease following the proposed Reverse Stock Split, we do not intend for the Reverse Stock Split to be the first step in a “going private transaction” within the meaning of Rule 13e-3 of the Exchange Act.

The Reverse Stock Split would not affect the par value, or any of the terms, of the Common Stock. After the Reverse Stock Split, all shares of Common Stock would have the same voting rights, and rights to dividends and other distributions (if any) by Synovus. At the effective time of the Reverse Stock Split, all shares of Common Stock other than fractional shares (the treatment of which is described below under “Fractional Shares”) would be reclassified and combined, automatically and without further action on the shareholders’ part, into the number of shares determined according to the 1-for-7 Reverse Stock Split ratio.

After the Reverse Stock Split is consummated, the Common Stock will have new Committee on Uniform Securities Identification Procedures (“CUSIP”) numbers, which is a number used to identify equity securities, and stock certificates with the older CUSIP numbers will need to be exchanged for stock certificates with the new CUSIP numbers by following the procedures described below.

After the Reverse Stock Split is consummated, we will continue to be subject to the periodic reporting and other requirements of the Exchange Act. Bid and ask prices for the Common Stock will continue to be quoted on the NYSE under the symbol “SNV.”

If this proposal is adopted, the Articles would be amended as set forth in Appendix D. Although Synovus intends to file the amendment with the Secretary of State of Georgia as promptly as possible after the amendment is approved by shareholders, the Board reserves the right to delay or abandon the amendment at its discretion.

The Board of Directors unanimously recommends that you vote “FOR” the approval of the amendment to Synovus’ Amended and Restated Articles of Incorporation to effect a 1-for-7 reverse stock split of Synovus’ Common Stock.

On April 26, 2010, our Board adopted a Shareholder Rights Plan (as amended as of September 6, 2011, the “Plan”) between the Company and American Stock Transfer & Trust Company, LLC (as successor to Mellon Investor Services LLC), as Rights Agent. The purpose of the Plan is to protect Synovus’ ability to use certain tax assets, such as net operating loss carryforwards, capital loss carryforwards and certain built-in losses (collectively, the “Tax Benefits”), to offset future income. Under the original terms of the Plan, the Rights (as defined below) were scheduled to expire on April 27, 2013. After careful consideration and based on advice of external legal counsel and tax advisors, our Board concluded that it was in the best interests of Synovus and our shareholders to extend the Plan and, on April 24, 2013, the Board approved an amendment to the Plan (the “Plan Amendment”) to (1) extend the final expiration date from April 27, 2013 to April 28, 2016 and (2) update certain contact information under the Notices section of the Plan. Except for the foregoing changes, the Plan Amendment resulted in no further changes to the Plan.

This proposal asks our shareholders to ratify the Plan Amendment.

Background and Reasons for the Proposal

The Plan was adopted to protect Synovus’ tax assets. Through December 31, 2013, Synovus has Tax Benefits that could offset approximately $1.3 billion of future federal taxable income and approximately $1.7 billion of future state taxable income. The future federal Tax Benefits expire between 2028 and 2033, and the future state Tax Benefits expire between 2014 and 2033. We can utilize the Tax Benefits in certain circumstances to offset taxable income and reduce our federal income tax liability. Synovus’ ability to use these Tax Benefits in the future may be significantly limited if we experience an “ownership change” as defined by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). As further described below, the Plan is designed to prevent certain acquisitions of Synovus stock which could adversely affect Synovus’ ability to use these Tax Benefits.

An ownership change under Section 382 generally occurs when a change in the aggregate percentage ownership of the stock of the corporation held by “five percent shareholders” increases by more than fifty percentage points over a rolling three year period. A corporation experiencing an ownership change generally is subject to an annual limitation on its utilization of pre-change losses and certain post-change recognized built-in losses equal to the value of the stock of the corporation immediately before the “ownership change,” multiplied by the long-term tax-exempt rate (subject to certain adjustments). An ownership change could occur, or the risk of an ownership change could be increased, if Synovus issues additional shares of its Common Stock, including shares issued in connection with an acquisition or business combination. If an ownership change under Section 382 occurred, the value of Synovus’ Tax Benefits could be impaired, and our ability to use these Tax Benefits could be adversely affected.

Transactions in Synovus stock during 2009 and 2010 increased the risk that Synovus could experience an ownership change in the future, including as a result of transactions that are not within Synovus’ control. Based upon these considerations, and advice of external counsel and legal advisors, our Board adopted the Plan in 2010 to reduce the likelihood that future transactions in our stock over a rolling three-year period will result in an ownership change.

During 2012 and early 2013, Synovus held extensive discussions regarding capital planning, including discussions regarding the amount

of additional capital that might be required to permit Synovus to redeem its obligations under TARP and the potential impact of such actions on its Tax Benefits. Even though the rolling three-year period for the 2009 and 2010 stock issues had passed, Synovus still faced the risk that an ownership change could occur in the future if Synovus issued additional shares of Common Stock, including any shares issued in connection with the redemption of its TARP obligations and any shares issued in connection with any future acquisitions or business combinations. In light of these capital planning discussions, after considering the substantial size of the Tax Benefits as of March 31, 2013, and with the advice of external legal counsel and tax advisors, our Board concluded that it was in the best interests of Synovus and our shareholders to adopt the Plan Amendment.

In general terms, the Plan discourages (1) any person or group from becoming a beneficial owner of 5% or more of Synovus’ then outstanding Common Stock (a “5% Shareholder”) and (2) any existing 5% or greater shareholder from acquiring additional shares of Synovus’ stock. There is no guarantee, however, that the Plan will prevent Synovus from experiencing an ownership change.

Unlike traditional shareholder rights plans (so-called poison pills) which are designed and put in place to deter unsolicited takeovers bids, the Plan was not adopted as an anti-takeover measure. The Plan is designed solely to protect Synovus’ Tax Benefits by deterring actions that could increase the likelihood of a loss of Tax Benefits. The Plan differs in certain key respects from a traditional shareholder tax benefits preservation plan, including that the Plan does not apply to acquisitions of a majority of Synovus’ Common Stock made in connection with an offer to acquire 100% of Synovus’ Common Stock, and the Plan (as amended by the Plan Amendment) will expire in April 2016 whereas traditional shareholder rights plans generally last for 10 years.

Description of the Plan

The following description of the Plan (as amended by the Plan Amendment) is qualified in its entirety by reference to the text of the Plan, which has been filed with the SEC and is available on the SEC’s web site (http://www.sec.gov). Please read the Plan in its entirety as the discussion below is only a summary.

The Rights. In connection with the adoption of the Plan on April 26, 2010, Synovus’ Board of Directors declared a dividend of one preferred stock purchase right (a “Right”) for each share of Common Stock outstanding of Synovus as of the close of business on April 29, 2010 (the “Tax Benefits Preservation Plan Record Date”). A Right will also be received with respect to each share of Common Stock issued after the Tax Benefits Preservation Plan Record Date. Each Right initially represents the right to purchase, for $12.00 (the “Purchase Price”), one one-millionth of a share of Series B Participating Cumulative Preferred Stock, no par value share (the “Series B Preferred Stock”). Any Rights held by an Acquiring Person (as defined below) are void and may not be exercised. The Board may exempt any person or group from being deemed an Acquiring Person if it determines, in its sole discretion, that such person’s or group’s attainment of 5% Shareholder status has not jeopardized or endangered Synovus’ utilization of the Tax Benefits.

Exercisability. The Rights are not exercisable until the earlier to occur of (1) the 10th business day after public announcement that any person or group has become an Acquiring Person; and (2) the 10th business day after the date of the commencement of a tender or exchange offer by any person which would or could, if consummated, result in such

person becoming an Acquiring Person, subject to extension by the Board prior to the expiration of the tender or exchange offer. The date that the Rights become exercisable is referred to as the “Distribution Date.” After any person has become an Acquiring Person, each Right (other than Rights treated as beneficially owned under certain U.S. tax rules by the Acquiring Person) will generally entitle the holder to purchase for the Purchase Price a number of shares of Series B Preferred Stock having a market value of twice the Purchase Price.

An “Acquiring Person” means generally any person or group that either becomes a beneficial owner of 5% or more of Synovus’ Common Stock then outstanding or a “5% shareholder” under the applicable U.S. tax regulations, other than: (1) the U.S. Government, its instrumentalities or agencies and certain of its wholly-owned entities; (2) Synovus and certain of its affiliates; (3) certain existing 5% Shareholders so long as such shareholder does not increase its percentage stock ownership of Synovus, except under certain limited circumstances; (4) any person or group that has become a 5% shareholder as a result of a redemption by Synovus so long as such person or group does not increase its percentage stock ownership of Synovus, except under certain limited circumstances; (5) no person or group that Synovus’ Board determines, in its sole discretion, has inadvertently become a 5% Shareholder so long as such person promptly divests (without exercising or retaining any power, including voting, with respect to such securities), sufficient shares of Synovus so that such person is no longer a 5% Shareholder; (6) any person or group that has become a 5% Shareholder if Synovus’ Board determines, in its sole discretion, that the attainment of such status has not jeopardized or endangered, and likely will not jeopardize or endanger, Synovus’ utilization of the Tax Benefits so long as such person or group does not increase its percentage stock ownership of Synovus, except under certain limited circumstances; (7) any person or group that acquires at least a majority of Synovus’ Common Stock in connection with an offer to acquire 100% of Synovus’ Common Stock then; and (8) any Strategic Investor (as defined in the Tax Benefits Preservation Plan) so long as the applicable Strategic Investor does not increase its percentage stock of Synovus’ Common Stock.

Exchange. At any time on or after the date on which a public announcement is made that any person becomes an Acquiring Person, the Board may elect to exchange all or part of the Rights (other than

Rights beneficially owned by the Acquiring Person and certain affiliated persons and their transferees) for one one-millionth of a share of Series B Preferred Stock (or one share of Common Stock) per Right, subject to adjustment.

Redemption. The Board may, at its option, redeem all, but not fewer than all, of the then outstanding Rights at a redemption price of $0.000001 per Right (the “Redemption Price”) at any time prior to a Distribution Date. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price for each Right so held.

Expiration. The Rights will expire on April 28, 2016, unless earlier exchanged or redeemed. While the timeframe for exhaustion of Synovus’ net operating losses will depend on Synovus’ actual taxable income for future periods, Synovus management estimates that the Rights will expire prior to the date on which Synovus would be able to utilize all of its existing Tax Benefits under current tax regulations.

Voting; Shareholder Rights. Holders of Rights have no rights as a shareholder of Synovus, including the right to vote or to receive dividends.

Antidilution Provisions. The Plan includes antidilution provisions designed to maintain the effectiveness of the Rights.

Amendments. At any time prior to a Distribution Date, the Plan may be amended in any respect unilaterally by Synovus. At any time after the occurrence of a Distribution Date, the Plan may be amended unilaterally by Synovus in any respect that does not adversely affect Rights holders (other than any Acquiring Person), (b) cause the Plan again to become amendable other than in accordance with this sentence or (c) cause the Rights again to become redeemable.

The Board of Directors unanimously recommends that you vote “FOR” the ratification of the amendment to the 2010 Tax Benefits Preservation Plan to extend the Plan.

The Audit Committee has appointed the firm of KPMG LLP as the independent auditor to audit the consolidated financial statements of Synovus and its subsidiaries for the fiscal year ending December 31, 2014 and Synovus’ internal control over financial reporting as of December 31, 2014. Although shareholder ratification of the appointment of Synovus’ independent auditor is not required by our bylaws or otherwise, we are submitting the selection of KPMG to our shareholders for ratification to permit shareholders to participate in this important corporate decision. If not ratified, the Audit Committee will reconsider the selection, although the Audit Committee will not be required to select a different independent auditor for Synovus.

KPMG served as Synovus’ independent auditor for the fiscal year ended December 31, 2013. Representatives of KPMG will be present at the Annual Meeting with the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from shareholders present at the meeting.

The Board of Directors unanimously recommends that you vote “FOR” ratification of the appointment of KPMG LLP as the independent auditor.

The Audit Committee of the Board of Directors is comprised of four directors, each of whom the Board has determined to be an independent director as defined by the listing standards of the NYSE and the categorical standards of independence set by the Board. The duties of the Audit Committee are summarized in this Proxy Statement under “Corporate Governance and Board Matters —Committees of the Board” beginning on page      and are more fully described in the Audit Committee charter adopted by the Board of Directors.

One of the Audit Committee’s primary responsibilities is to assist the Board in its oversight responsibility regarding the integrity of Synovus’ financial statements and systems of internal controls. Management is responsible for Synovus’ accounting and financial reporting processes, the establishment and effectiveness of internal controls and the preparation and integrity of Synovus’ consolidated financial statements. KPMG LLP, Synovus’ independent auditor, is responsible for performing an independent audit of Synovus’ consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and issuing opinions on whether those financial statements are presented fairly in conformity with accounting principles generally accepted in the United States and on the effectiveness of Synovus’ internal control over financial reporting. The Audit Committee is directly responsible for the compensation, appointment and oversight of KPMG LLP. The function of the Audit Committee is not to duplicate the activities of management or the independent auditor, but to monitor and oversee Synovus’ financial reporting process.

In discharging its responsibilities regarding the financial reporting process, the Audit Committee:

Based upon the review and discussions referred to in the preceding paragraph, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements referred to above be included in Synovus’ Annual Report on Form 10-K for the year ended December 31, 2013 filed with the Securities and Exchange Commission.

The Audit Committee has the responsibility for appointing, setting the compensation for and overseeing the work of Synovus’ independent auditor. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent auditor in order to assure that the

provision of these services does not impair the independent auditor’s independence. Synovus’ Audit Committee Pre-Approval Policy addresses services included within the four categories of audit and permissible non-audit services, which include Audit Services, Audit Related Services, Tax Services and All Other Services.

The Audit Committee uses a combination of two approaches to pre-approve audit and permitted non-audit services performed by the independent auditor, class pre-approval and specific pre-approval. The annual audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. In addition, the Audit Committee must specifically approve permissible non-audit services classified as All Other Services.

Prior to engagement, management submits to the Committee for approval a detailed list of the Audit Services, Audit Related Services and Tax Services that it recommends the Committee engage the independent auditor to provide for the fiscal year. Each service is allocated to the appropriate category and where specific pre-approval is required, the specific service is accompanied by a budget estimating the cost of that service. The Committee will, if appropriate, approve both the list of Audit Services, Audit Related Services and Tax Services, the

classification of the service and where specific pre-approval is required, the budget for such services.

The Committee is informed at each Committee meeting as to the services actually provided by the independent auditor pursuant to the Pre-Approval Policy. Any proposed service that is not separately listed in the Pre-Approval Policy or any service exceeding the pre-approved fee levels must be specifically pre-approved by the Committee. The Audit Committee has delegated pre-approval authority (on engagements not exceeding $100,000) to the Chairman of the Audit Committee. The Chairman must report any pre-approval decisions made by him to the Committee at its next scheduled meeting.

All of the services described in the table above under the captions “Audit Fees,” “Audit Related Fees,” “Tax Fees” and “All Other Fees” were approved by the Committee pursuant to legal requirements and the Committee’s Charter and Pre-Approval Policy.
