2017 Financial Performance

Our 2017 financial results were in line with our 2017 guidance and overarching objectives. Our continued focus on sustainable growth, enhanced profitability and greater efficiency led to broad-based improvement. This improvement was evident for the year through our performance in several key financial measurements—earnings per share growth, return on average assets, return on average common equity and the efficiency ratio, with each

measurement exhibiting notable progress. Moreover, during 2017, we achieved our previously established long-term targets of a 10+% earnings per share growth, 1.0+% adjusted return on average assets, 10.0+% adjusted return on average common equity and a sub 60% efficiency ratio.

In addition, we continued to return meaningful levels of capital to our common shareholders in 2017 through common stock dividends and share repurchases.

For additional information relating to our business and our subsidiaries, including a detailed description of our operating results and financial condition for 2017, 2016 and 2015, please refer to the summary on page 30 of this Proxy Statement and our 2017 Annual Report that accompanies this Proxy Statement.

VOTING INFORMATION

Internet Availability of Proxy Materials

As permitted by the federal securities laws, Synovus is making this Proxy Statement and its 2017 Annual Report available to its shareholders via the Internet instead of mailing printed copies of these materials to each shareholder. On March 16, 2018, 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 2017 Annual Report. These proxy materials are being made available to our shareholders on or about March 16, 2018. The Notice also provides instructions regarding how to access your proxy card to vote through the Internet or by telephone. The Proxy Statement and 2017 Annual Report are also available on our website at investor.synovus.com/2018annualmeeting.

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.

Who Can Vote

You are entitled to vote if you were a shareholder of record of Synovus common stock as of the close of business on February 22, 2018. 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.

Quorum and Shares Outstanding

A majority of the votes entitled to be cast by the holders of the outstanding shares of Synovus common stock must be present, either in person or represented by proxy, in order to conduct the Annual Meeting. This is referred to as a quorum. On February 22, 2018, 118,680,133 shares of Synovus common stock were outstanding.

Proxies

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.

Required Votes

The number of affirmative votes required to approve each of the proposals to be considered at the Annual Meeting is described below:

Proposal 1    Election of 14 Directors

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.

All Other Proposals

For all of the other proposals described in this Proxy Statement, the affirmative vote of a majority of the votes cast is required to approve each such proposal.

VOTING INFORMATION

Abstentions and Broker Non-Votes

Under certain circumstances, including the election of directors, matters involving executive compensation and other matters considered non-routine, 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, 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 3 but not with respect to any of the other proposals to be voted on at the Annual Meeting.

Abstentions and broker non-votes will have no effect on any of the proposals to be considered at the Annual Meeting.

How You Can Vote

If you hold shares in your own name, you may vote by proxy or in person at the Annual Meeting. To vote by proxy, you may select one of the following options:

Vote By Telephone

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 25, 2018. 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.

Vote By Internet

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 25, 2018. 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.

Vote By Mail

If you choose to vote by mail, simply mark your proxy card, date and sign it, sign the certification (if applicable) and return it in the postage-paid envelope provided.

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.

Description of Voting Rights

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 meeting any one of the following criteria are entitled to ten votes on each matter submitted to a vote of shareholders for each share of Synovus common stock owned on February 22, 2018 which: (1) has had the same beneficial owner since April 24, 1986; or (2) has been beneficially owned continuously by the same shareholder since February 22, 2014; or (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; or (4) is held by the same beneficial owner to whom it was issued by Synovus, or to whom it was 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; or (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; or (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 162,723 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 one of the criteria above for being entitled to ten votes per share.

- 2018 Proxy Statement    5

VOTING INFORMATION

For purposes of the foregoing, any share of our common stock held in “street” or “nominee” name shall be presumed to have been acquired by the beneficial owner subsequent to April 24, 1986 and to have had the same beneficial owner for a continuous period of less than 48 months prior to February 22, 2018. This presumption shall be rebuttable by presentation to our Board of Directors by such beneficial owner of evidence satisfactory to our Board of Directors that such share has had the same beneficial owner continuously since April 24,1986 or such share has had the same beneficial owner for a period greater than 48 months prior to February 22, 2018.

In addition, 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 Synovus’ 10-1 Voting Instructions and the accompanying voting instruction worksheet that are available on our website at investor.synovus.com/2018annualmeeting.

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.

Synovus Stock Plans

If you participate in the Synovus Dividend Reinvestment and Direct Stock Purchase Plan, the Synovus Employee Stock Purchase Plan and/or the Synovus Director Stock Purchase Plan, your proxy card represents shares held in the respective plan, as well as shares you hold directly in certificate form registered in the same name. If you hold shares of Synovus common stock through a 401(k) plan, you will receive a separate proxy card representing those shares of Synovus common stock.

Revocation of Proxy

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 25, 2018, 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.

Attending the Annual Meeting

The Annual Meeting will be held on Thursday, April 26, 2018, at 10:00 a.m. at Blanchard Hall, Synovus Bank, 1144 Broadway, Columbus, Georgia. Directions to Blanchard Hall may be obtained on our website at investor.synovus.com/2018annualmeeting.

CORPORATE GOVERNANCE AND BOARD MATTERS

Corporate Governance Philosophy

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. The Board strives to ensure the success and continuity of Synovus’ business through the appointment of qualified executive 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 following sound corporate governance.

Corporate Governance Highlights

Synovus’ Board and management believe that good corporate governance practices promote the long-term interests of all shareholders and strengthen Board and management accountability. Highlights of such practices 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.

Independence

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 investor.synovus.com.

The Board has affirmatively determined that thirteen of its fourteen 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, 2018, the following directors are independent: Catherine A. Allen, Tim E. Bentsen, F. Dixon Brooke, Jr., Stephen T. Butler, Elizabeth W. Camp, Diana M. Murphy, Jerry W. Nix, Harris Pastides, Joseph J. Prochaska, Jr., John L. Stallworth, Melvin T. Stith, Barry L. Storey and Philip W. Tomlinson. Please see “Certain Relationships and Related Transactions” on page 46 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.

CORPORATE GOVERNANCE AND BOARD MATTERS

Board Meetings and Attendance

The Board of Directors held eleven meetings in 2017. All directors attended at least 75% of Board and committee meetings held during their tenure during 2017. The average attendance by incumbent directors at the aggregate number of Board and committee meetings they were scheduled to attend was approximately 98%. 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’ then-current directors attended Synovus’ 2017 annual meeting of shareholders.

Board meetings regularly include education presentations and training to enable the directors to keep abreast of business and banking trends and market, regulatory and industry issues. These sessions are often conducted by outside experts in such subject areas as cybersecurity, evolving regulatory standards, risk management, emerging products and trends, economic conditions, technology and effective corporate governance. In addition, the Board is provided business-specific training on products and services and special risks and opportunities to Synovus. Moreover, the directors periodically attend industry conferences, meetings with regulatory agencies and educational sessions pertaining to their service on the Board and its committees.

Committees of the Board

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 investor.synovus.com. 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.

Audit Committee

Synovus’ Audit Committee held thirteen meetings in 2017. The Audit Committee’s report is on page 27 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 each of the four members of the Audit Committee is an “audit committee financial expert” as defined by the rules of the SEC. The primary functions of the Audit Committee include:

Corporate Governance and Nominating Committee

Synovus’ Corporate Governance and Nominating Committee held five meetings in 2017. The primary functions of Synovus’ Corporate Governance and Nominating Committee include:

Compensation Committee

Synovus’ Compensation Committee held five meetings in 2017. Its report is on page 40 of this Proxy Statement. The primary functions of the Compensation Committee include:

Information regarding the Compensation Committee’s processes and procedures for considering and determining executive officer compensation is provided in the “Executive Compensation—Compensation Discussion and Analysis” section of this Proxy Statement. Except to the extent prohibited by law or regulation, the Compensation Committee may delegate matters within its power and responsibility to individuals or subcommittees when it deems appropriate.

In addition, the Compensation Committee has the authority under its charter to retain outside advisors to assist the Committee in the performance of its duties. During 2017, 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 Administrative Officer and her staff developed executive compensation recommendations for the Committee’s consideration in conjunction with Synovus’ CEO and with the advice of Meridian. Meridian did not provide any other services to Synovus during 2017.

- 2018 Proxy Statement    9

CORPORATE GOVERNANCE AND BOARD MATTERS

In 2017, Synovus’ Chief Administrative Officer worked with the Chairman of the Committee to establish the agenda for Committee meetings. Management also prepares background information for each committee meeting. Synovus’ Chief Administrative Officer and Chief Human Resources Officer attend all committee meetings by invitation of the Committee, while Synovus’ CEO attends some committee meetings by invitation of the Committee. The CEO and other members of management do not have authority to vote on committee matters. Meridian attended all of the committee meetings held during 2017 at the request of the Committee. In addition, the Committee regularly meets in executive session with no members of management in attendance.

Risk Committee

Synovus’ Risk Committee held eight meetings in 2017. The primary functions of Synovus’ Risk Committee include:

Executive Committee

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. 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 did not meet in 2017.

Compensation Committee Interlocks and Insider Participation

Ms. Camp and Messrs. Brooke, Stith, Storey and Tomlinson served on the Compensation Committee during 2017. In addition, Michael T. Goodrich served on the Compensation Committee until his retirement in April 2017. None of these individuals is or has been an officer or employee of Synovus. In 2017, none of our executive officers served on the board of directors or compensation committee of any entity that had one or more of its executive officers serving on Synovus’ Board or Compensation Committee.

Risk Oversight

Under Synovus’ Corporate Governance Guidelines, the Board is charged with providing oversight of Synovus’ risk management processes. The Board does not view risk in isolation and considers risk in virtually every business decision and as part of the Company’s overall business strategy. While the Board oversees risk management, the Company’s management is charged with managing risk. 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’ 2017 Annual Report.

The Risk Committee fulfills the overarching oversight role for overseeing the enterprise risk management and compliance processes, including approving 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, interest rates, credit, operations, regulatory compliance, and future growth, among others) and the processes in place to monitor and control such exposures. The Chairman of the Risk Committee also receives updates between meetings from the Chief Risk Officer, the Chief Executive Officer, the Chief Information Security Officer and the Chief Compliance Officer 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, oversight of risk is allocated to all other committees of the Board, who meet regularly and report back to the Board. The Audit Committee oversees risks related to financial reporting, internal controls over financial reporting, the investments portfolio, legal matters, tax matters, credit matters and reputational risks relating to these areas. The Compensation Committee oversees risks related to incentive compensation, executive and director compensation, executive succession planning, talent retention and reputational risks relating to these areas. As a part of the risk governance process, the Chief Risk Officer provides an annual risk profile of our compensation plans to the Compensation Committee. 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 Framework: Compensation Policies, Compensation Process and Risk Considerations—Risk Considerations” on page 39 of this Proxy Statement. The Corporate Governance and Nominating Committee oversees corporate governance-related

risks, such as board succession planning, corporate governance policies, related party transactions, and reputational risks relating to these areas.

The Company believes that its enterprise risk framework, including the active engagement of management with the Board in the risk oversight function, supports the risk oversight function of the Board. For more information on the risks facing the Company, see the risk factors in “Part I—Item 1A. Risk Factors” in the 2017 Annual Report.

Leadership Structure of the Board

Our current Board leadership structure consists of:

Our Corporate Governance Guidelines and governance framework provide the Board with flexibility to select the appropriate leadership structure for Synovus. In making leadership structure determinations, the Board considers many factors, including the specific needs of the business and what is in the best interests of Synovus’ shareholders. 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 roles 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 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. Moreover, as part of the Board’s annual self-evaluation, the performance of the Chairman of the Board and Lead Director are evaluated, and the Board continues to believe that the current Board structure is appropriate and effective.

Meetings of Non-Management and Independent Directors

The non-management directors of Synovus meet separately at least four times a year after regularly scheduled meetings of the Board of Directors and at such other times as may be requested by the Chairman of the Board or any director. Synovus’ independent directors meet at least once a year. During 2017, Mr. Goodrich, as Lead Director until April 2017, and Ms. Camp, as Lead Director since April 2017, presided at the meetings of non-management and independent directors.

CORPORATE GOVERNANCE AND BOARD MATTERS

Board and Committee Self-Evaluations

The Board and each Board committee conduct robust annual self-evaluations to assess the qualifications, attributes, skills and experience represented on the Board and its committees and to determine whether the Board and its committees are functioning effectively. The results of the self-evaluations are discussed by the Board and each committee, respectively, during executive session. For the last four years, the Board has used an independent third party to conduct these evaluations.

The Board’s annual self-evaluation is a key component of its director nomination process and succession planning. In fact, the Corporate Governance and Nominating Committee uses the input from these self-evaluations to recommend changes to Synovus’ corporate governance practices and areas of focus for the following year and to plan for an orderly succession of the Board and its committees. The Board values the contributions of directors who have developed extensive experience and insight into Synovus during the course of their service on the Board and as such, the Board does not believe arbitrary term limits on directors’ service are appropriate. At the same time, the Board recognizes the importance of Board refreshment to help ensure an appropriate balance of experience and perspectives on the Board.

Consideration of Director Candidates

Director Qualifications

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 be 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 16 of this Proxy Statement.

Identifying and Evaluating Nominees

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, as authorized under its charter, retains 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, as well as any candidates identified by shareholders through the process described below, 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.

12		- 2018 Proxy Statement

CORPORATE GOVERNANCE AND BOARD MATTERS

Shareholder Candidates

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 47 of this Proxy Statement.

Communicating with the Board

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:

Relevant communications are distributed to the Board, or to any individual director or directors, as appropriate, depending upon the facts and circumstances outlined in the communication. In that regard, the Board has requested that certain items that are unrelated to its duties and responsibilities be excluded, such as: business solicitations or advertisements; junk mail and mass mailings; resumes and other forms of job inquiries; spam; and surveys. In addition, material that is unduly hostile, threatening, illegal or similarly unsuitable will be excluded. Any communication that is filtered out is made available to any director upon request.

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

Shareholder Engagement

Synovus and our Board believe that accountability to our shareholders is key to sound corporate governance principles, and as such, regular and transparent communication with our shareholders is essential to our long-term success. Throughout 2017, members of our management team met regularly with a significant number of our shareholders to discuss our corporate strategy, capital management, risk management, corporate governance and executive compensation. In regularly engaging with our shareholders, we provide perspective on our policies and practices and seek input from these shareholders to ensure that we are addressing their questions and concerns.

Additional Information about Corporate Governance

After careful planning and discussion, the Board recently amended the mandatory retirement age of the Board, effective with the Annual Meeting, to the later of age 72 or seven years of Board service (but in no event shall a director serve after attaining age 75). The Board made this change as a part of a deliberative succession planning process, recognizing the upward trends in public board retirement ages and balancing the need for highly qualified candidates with the time and commitment required for director onboarding and education. We believe this change will be in the best interests of our shareholders by ensuring a Board comprised of highly qualified individuals, highly committed and engaged in our Company’s long-term success.

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 investor.synovus.com.

DIRECTOR COMPENSATION

Director Compensation Program

The Compensation Committee is responsible for the oversight and administration of the Synovus director compensation program. The following is a description of the director compensation program for 2017.

Cash Compensation of Directors

As reflected in the “Fees Earned or Paid in Cash” column of the Director Compensation Table, during 2017, non-management directors of Synovus received an annual cash retainer of $50,000, 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.

The members of the Board are 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 2017 for the full year of service for the period from April 20, 2017 through April 26, 2018.

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. Three directors (Dr. Pastides and Messrs. Stallworth and Storey) elected to defer their 2017 cash compensation under this plan.

Equity Compensation of Directors

During 2017, non-management directors also received awards of restricted stock units under the Synovus 2013 Omnibus Plan. On April 19, 2017, the Board approved grants of 1,782 restricted stock units ($75,000 grant date fair market value) to the non-management members of the Board elected on April 20, 2017 to serve as directors for a term ending on April 26, 2018. The director restricted stock units become fully vested and transferable upon the earlier to occur of the completion of three years of service following the grant date and the date the holder reaches mandatory retirement, as set forth in the Corporate Governance Guidelines. 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 may 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 may 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 2017). 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.

Director Stock Ownership Guidelines

Synovus’ Corporate Governance Guidelines require all directors to accumulate over time shares of Synovus stock equal in value to at least five 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. The restricted stock unit awards to directors and Synovus’ contributions under the Director Stock Purchase Plan assist and facilitate directors’ fulfillment of their stock ownership requirements. All of Synovus’ directors were in compliance with the guidelines as of December 31, 2017.

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. Each year, as required by Section 14A of the Securities Exchange Act, we give you, as a shareholder, the opportunity to endorse the compensation for our named executive officers. The proposal described below, commonly known as a “Say on Pay” proposal, gives you the opportunity to approve, on an advisory basis, such compensation as described in this Proxy Statement.

In deciding how to vote on this proposal, the Board encourages you to read the “Executive Compensation—Compensation Discussion and Analysis” section of this Proxy Statement and the tabular and narrative disclosure which follows it. In those sections, we discuss each element of compensation, including base salaries, short-term incentives, long-term incentives and retirement benefits. We also discuss our policies and other factors which affect the decisions of our Compensation Committee.

In many cases, we are required to disclose in the executive compensation tables accounting or other non-cash estimates of future compensation. Because of this, we encourage you to read the footnotes and narratives which accompany each table in order to understand any non-cash items.

We believe our executive compensation is aligned with shareholders because:

We believe that the compensation delivered to each named executive officer in 2017 was fair and reasonable.

Unless the Board modifies its policy on the frequency of future “Say on Pay” advisory votes, the next “Say on Pay” vote will be held at the 2019 annual meeting of shareholders. The next advisory vote on the frequency of “Say on Pay” proposals is scheduled to occur at the 2020 annual meeting of shareholders.

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, 2018 and Synovus’ internal control over financial reporting as of December 31, 2018. KPMG has been appointed continuously since 1975. 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.

The Audit Committee annually reviews KPMG’s independence and performance in connection with the determination to retain KPMG. In conducting its review this year, the Audit Committee considered, among other things:

Based on the results of its review this year, the Audit Committee concluded that KPMG is independent and that it is in the best interests of Synovus and its shareholders to appoint KPMG LLP to serve as Synovus’ independent auditor for 2018.

Synovus’ Audit Committee oversees the process for, and ultimately approves, the selection of the independent auditor’s lead engagement partner at the five-year mandatory rotation period. At the Audit Committee’s instruction, KPMG selects candidates to be considered for the lead engagement partner role, who are then interviewed by members of Synovus’ senior management. After discussing the results of senior management’s interviews, the members of the Audit Committee, as a group, interview the candidates. The Audit Committee then considers the appointment and votes on the selection.

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 for the year 2018.

- 2018 Proxy Statement    25

STOCK OWNERSHIP OF DIRECTORS AND NAMED EXECUTIVE OFFICERS

Pursuant to Synovus’ Articles of Incorporation and bylaws, certain shares of Synovus common stock are entitled to ten votes per share, including shares which (1) have been beneficially owned continuously by the same shareholder since February 22, 2014; (2) have been held by the same beneficial owner to whom the shares were 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 to such shares; (3) have been 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 have been held by the same owner for whom it was acquired under any such plan; (4) have been acquired by reason of participation in a dividend reinvestment plan offered by Synovus and have been held by the same owner for whom the shares were acquired under any such plan; or (5) have been owned by a holder who, in addition to certain other shares, is the owner of less than 162,723 shares of Synovus common stock. Applying these standards, we believe that all of the shares of Synovus common stock set forth in the table above are entitled to ten votes per share.

Based upon the total voting power certified at Synovus’ 2017 Annual Meeting of Shareholders, (1) the voting power of each of the directors and named executive officers, other than Messrs. Butler and Stelling, would represent less than 1% of the total voting power, (2) Mr. Butler’s beneficial ownership would represent approximately 4.6% of the total voting power, 3.1% of which is disclaimed by Mr. Butler, (3) Mr. Stelling’s beneficial ownership would represent approximately 1.2% of the total voting power, and (4) directors and executive officers as a group would represent approximately 8.8% of the total voting power, 3.1% of which is disclaimed by Mr. Butler.

AUDIT COMMITTEE REPORT

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 8 and are more fully described in the Audit Committee charter adopted by the Board of Directors. A copy of the Audit Committee charter is available in the Corporate Governance section of our website at investor.synovus.com.

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:

The Audit Committee has discussed with Synovus’ internal auditors and KPMG LLP the overall scope and plans for their respective audits. The Audit Committee regularly meets with Synovus’ internal auditors and KPMG, with and without management present, to discuss the results of their examinations and their observations and recommendations regarding Synovus’ internal controls.

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, 2017 filed with the Securities and Exchange Commission.

AUDIT COMMITTEE REPORT

Policy on Audit Committee Pre-Approval

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. Class pre-approval is reserved for certain limited audit, audit-related and tax services, as approved by the Audit Committee each year. All other services performed by the independent auditor must be specifically pre-approved by the Audit Committee. For instance, 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.

Executive Summary

Synovus 2017 Performance

Our 2017 financial results were in line with our 2017 guidance and overarching objectives. Our continued focus on sustainable growth, enhanced profitability and greater efficiency led to broad-based improvement. This improvement was evident for the year through our performance in several key financial measurements—earnings per share growth, return on average assets, return on average common equity and the efficiency ratio, with each measurement exhibiting notable progress. Moreover, during 2017, we achieved our previously established long-term targets of a 10+% earnings per share growth, 1.0+% adjusted return on average assets, 10.0+% adjusted return on average common equity and a sub 60% efficiency ratio.

*For a reconciliation of the foregoing non-GAAP financial measures, including adjusted net income per diluted common share, adjusted total revenues, adjusted non-interest income, adjusted return on average assets, adjusted non-interest expense, adjusted efficiency ratio, average core transaction deposit accounts, adjusted net-charge off ratio, adjusted return on average common equity, return on average tangible common equity, adjusted return on average tangible common equity, and tangible book value per common share, please refer to Appendix B of this Proxy Statement.

Results of 2016 Advisory Vote to Approve Executive Compensation

At the 2017 annual meeting of shareholders, we held an advisory vote on executive compensation for 2016. Over 96% of the votes cast were in favor of this advisory proposal. The Compensation Committee considered this favorable outcome and believed the results conveyed our shareholders’ support of our executive compensation programs and did not make any specific changes to our executive compensation programs as a result of this vote. At the Annual Meeting, we will again hold an annual advisory vote to approve executive compensation paid in 2017. The Compensation Committee will continue to consider the results from this year’s and future advisory votes on executive compensation.

Compensation Philosophy and Key Considerations

Synovus has established a compensation program for our executives that is performance-oriented and designed to support our strategic goals. Our compensation philosophy, as well as how our program aligns with the philosophy, is described in the table below.

32		- 2018 Proxy Statement

EXECUTIVE COMPENSATION

Elements and Mix of Compensation for Past Fiscal Year

Synovus has a performance-oriented executive compensation program that is designed to support our corporate strategic goals, including growth in earnings and growth in shareholder value. The elements of our regular total compensation program and the objectives of each element are identified in the following table and discussed in more detail below:

2017 CEO Compensation Changes

In 2016 and early 2017, the Committee evaluated the CEO’s compensation relative to his performance, the Company’s performance and compensation levels of peers CEOs. In evaluating the Company’s performance, the Committee considered Synovus’ top quartile shareholder returns relative to peers.

The Committee discussed potential changes to Mr. Stelling’s compensation based on the following objectives:

- 2018 Proxy Statement    33

EXECUTIVE COMPENSATION

Based on its review, the Committee determined to increase Mr. Stelling’s target compensation opportunity in February 2017. Specifically, the Committee increased his base salary from $995,000 to $1,125,000, established his award bonus target at 125%, and granted him 30,041 PSUs and 30,041 MRSUs. For additional information, see “Short-Term Incentive Decisions in 2017” below for details regarding the CEO’s 2017 annual incentive payout and “Long-Term Incentive Decision in 2017” below for details regarding the PSUs and MRSUs. The changes positioned the CEO’s total target compensation between the 50^th and 75^th percentile of the Company’s peers.

The graph below provides Synovus’ shareholder return relative to peers since the beginning of 2014 and the CEO’s compensation, as calculated in the Summary Compensation Table (SCT), over the same time period.

Base Pay Decisions in 2017

In addition to the increase for Mr. Stelling described above, the Compensation Committee awarded 2% base salary increases (rounded up to the nearest $250) for Synovus’ other named executive officers, effective July 19, 2017. While the Committee reviewed market comparisons and recognized that some cash salaries were below the market median, base salary increases were generally limited to 2% to remain consistent with the base salary percentage increases received by other team members at Synovus. As a result, individual performance was not a factor used in determining base pay for Synovus’ named executive officers in 2017.

Short-Term Incentive Decisions in 2017

In 2017, the formulaic performance goals for our cash-based short-term incentive plan were based 60% on core earnings, 20% on adjusted pre-provision net revenue and 20% on adjusted efficiency ratio. In addition, the Committee also reviewed performance on several qualitative factors, including: quality of earnings, quality of loan growth (including consideration of concentration limits), quality of deposit growth, expense management, single bank conversion, credit quality (including the nonperforming assets ratio, nonperforming loans ratio and net charge-off ratio), financial impact of strategic investments, external factors (including the impact of Federal Reserve rate increases vs. budget assumptions), regulatory compliance, risk management, total shareholder return and individual performance. Actual payouts under the plan may vary from 0% to 150% of the target based upon Synovus and each executive’s performance in these areas compared to the performance goals. Target awards for 2017, expressed as a percentage of base salary, were 125% for Mr. Stelling, 75% for Mr. Blair, 70% for Mr. Gula and 60% for each of Messrs. Kamensky and Singleton.

The following chart summarizes the performance goals in each category for threshold, target and maximum payouts as well as the actual performance:

34		- 2018 Proxy Statement

EXECUTIVE COMPENSATION

The Committee considered the following discretionary factors, which can be used for upward or downward adjustments, prior to awarding annual incentives:

*For a reconciliation of the foregoing non-GAAP financial measures to the most comparable GAAP measure, including core earnings, adjusted non-interest expense, adjusted efficiency ratio, average core deposits, and average core transaction accounts, please refer to Appendix B of this Proxy Statement.

Based on the results of the performance goals and consideration of the discretionary factors described above, including strong individual performance as reflected in his performance evaluation, the Committee approved an annual incentive award payout of 139.81% of target for Mr. Stelling. Based on the results of the performance goals and consideration of the discretionary factors listed above, the Committee approved payouts ranging from 135% to 145% of target for each of the Company’s other named executive officers. The annual short-term incentive award payout amount for each named executive officer is set forth in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table set forth on page 41 of this Proxy Statement.

Long-Term Incentive Decisions in 2017

In 2017, we granted long-term incentives through a combination of 50% PSUs and 50% MRSUs. All of our long-term incentive awards are linked to Synovus’ future performance. Individual long-term incentive award amounts were determined after the Committee reviewed market comparisons for similarly-situated positions. The Committee granted Mr. Stelling PSUs and MRSUs as described in “2017 CEO Compensation Changes” above. The Committee also granted the Company’s other named executive officers long-term incentive awards for 2017 as set forth in the “Estimated Future Payouts Under Equity Incentive Plan Awards” column of the Grants of Plan-Based Awards Table on page 42 of this Proxy Statement.

Performance Stock Units (PSUs)

The PSUs have both a performance vesting component and a service vesting component. Under the performance vesting component, Synovus’ weighted average ROAA (as adjusted) is measured over a three-year performance period. The performance goal approved by the Committee is based upon the Company’s objectives under its strategic plan. The actual payout of the PSUs may range from 0% to 150% of the target amount based upon Synovus’ weighted average ROAA (as adjusted) during the performance period compared to the performance formula approved by the Compensation Committee. The performance formula places a higher weighting on the third year of the performance period. The service vesting component specifies that shares earned based on performance results will vest after three years of service.

Payout for 2015-2017 PSUs. The following charts show the calculation of the payout for the PSUs granted in 2015, which paid out at 98.48% of target on February 19, 2018 based on a weighted average ROAA (as adjusted) of 0.921% for the 2015-2017 performance period:

ROAA (as adjusted) Performance Calculation

Performance Goals and Payout Calculation

Market Restricted Stock Units (MRSUs)

The MRSUs have a service-based vesting component as well as a Total Shareholder Return Multiplier. Under the service-based vesting component, the MRSUs vest one-third each year over a three-year period subject to each executive’s continued employment with Synovus. Under the Total Shareholder Return Multiplier, the “target” amount of MRSUs which vest each year will be adjusted upward or downward up to 25% based upon Synovus’ total shareholder return during each year. MRSUs align executives’ interests directly with shareholders while supporting retention, and were granted in lieu of including any time-based restricted stock in our executive compensation program. The following chart shows the actual payout amounts for previously-granted MRSUs that were granted or that vested during 2017:

Both the PSUs and MRSUs are subject to downward adjustment if future results suggest risk was not properly considered in achieving the results on which the number of units awarded were based. The Compensation Committee will consider if reductions are warranted if any of the following occur during the vesting period: (1) Synovus or a line of business experiences a material loss, (2) Synovus or an individual executive fails to comply with risk policies or properly address risk concerns, or (3) regulatory capital falls below regulatory capital requirements. The Committee did not exercise downward discretion with respect to the PSUs or MRSUs that vested during 2017.

Perquisites

Perquisites, which are not tied to performance, are a small part of our executive compensation program. Perquisites are offered to align our compensation program with competitive practices because similar positions at Synovus’ competitors offer similar perquisites. The perquisites offered by Synovus in 2017 were limited to the payment of club dues, financial planning, an auto allowance and security alarm monitoring for certain officers. In addition, perquisites included transportation services and a housing allowance for Mr. Stelling and relocation assistance for Mr. Blair. The Company’s incremental cost of providing these benefits is included as “All Other Compensation” in the Summary Compensation Table and is

36		- 2018 Proxy Statement

EXECUTIVE COMPENSATION

described in more detail in footnotes 3 and 4 of the Summary Compensation Table on page 41 of this Proxy Statement. Considered both individually and in the aggregate, we believe that the perquisites we offer to our named executive officers are reasonable and appropriate.

The Committee suspended the personal use of aircraft by the Company’s executives in 2009, although the Committee may approve exceptions to that policy. No exceptions were approved during 2017.

Retirement and Deferred Compensation Plans

Our compensation program also includes retirement plans designed to provide income following an executive’s retirement. Synovus’ compensation program is designed to reflect Synovus’ philosophy that compensation generally should be earned while actively employed. Although retirement benefits are paid following an executive’s retirement, the benefits are earned while employed. We have chosen to use defined contribution retirement plans because we believe that defined benefit plans are difficult to understand and communicate, and contributions to defined benefit plans often depend upon factors that are beyond Synovus’ control, such as the earnings performance of the assets in such plans compared to actuarial assumptions inherent in such plans. Synovus offered two qualified defined contribution retirement plans to its employees in 2017: a profit sharing plan and a 401(k) savings plan. The profit sharing plan was merged into the 401(k) savings plan effective December 29, 2017. The 401(k) savings plan offers an employer matching contribution of up to 4% of compensation (5% beginning on January 1, 2018).

In addition to these plans, the Deferred Compensation Plan, or the Deferred Plan, replaces benefits foregone under the qualified plans due to legal limits imposed by the Internal Revenue Service, or IRS. The Deferred Plan does not provide “above market” interest. Instead, participants in the Deferred Plan can choose to invest their accounts among mutual funds that are the same as the mutual funds that are offered in the 401(k) savings plan. The executives’ Deferred Plan accounts are held in a rabbi trust, which is subject to claims by Synovus’ creditors. The employer matching contribution to the Deferred Plan for 2017 for named executive officers is set forth in the “All Other Compensation” column in the Summary Compensation Table, and the earnings on the Deferred Plan accounts during 2017 for named executive officers is set forth in the “Aggregate Earnings in Last FY” column in the Nonqualified Deferred Compensation Table. Mr. Stelling also participates in a deferred compensation plan entered into with Riverside Bank, or the Riverside Plan, prior to Riverside Bank’s acquisition by Synovus. The obligations under the Riverside Plan, which was initially effective January 1, 2003, were assumed by Synovus Bank when Synovus consolidated its banking charters in 2010. Under the Riverside Plan, the beginning benefit amount specified in the plan is increased by 3% for each year of service attained by Mr. Stelling. The total benefit amount under the Riverside Plan is payable to Mr. Stelling in monthly payments over a period of 15 years following his attainment of age 65 or in a single lump sum payment in the event of his death or disability. The total benefit amount under the Riverside Plan as of December 31, 2017 is included in Mr. Stelling’s balance in the Nonqualified Deferred Compensation Table and Synovus’ contribution to the Riverside Plan for 2017 is included in the “All Other Compensation” column in the Summary Compensation Table.

Employment and Termination Agreements

Synovus does not generally enter into employment agreements with its executives, except in unusual circumstances such as acquisitions. None of the named executive officers have employment agreements. Synovus uses change of control arrangements with its executives to ensure: (1) the retention of executives and an orderly transition during a change of control, (2) that executives would be financially protected in the event of a change of control so they continue to act in the best interests of Synovus while continuing to manage Synovus during a change of control, and (3) a competitive compensation package because such arrangements are common in the market and it was determined that such agreements were important in recruiting executive talent. The change of control agreements provide for a lump sum payment equal to three years of base salary and the affected executive’s average bonus for the past three years, as well as three years of health and welfare benefits. These payments and benefits are paid only in the event of a “double trigger,” requiring a change of control followed by termination of an executive’s employment by Synovus for any reason other than “cause,” death or disability, or by the executive for “good reason,” within two years of the change of control. In June 2012, the Committee adopted a policy prohibiting tax gross-ups from any new change of control agreements.

Competitive Market Data

The Compensation Committee historically has evaluated comparative data relating to total direct compensation (salary, short-term incentive opportunities, and long-term incentive opportunities) to assess the executive compensation practices of competitor companies. The Committee continued this practice in 2017, with the assistance of Meridian. Findings from this comparative evaluation were used to assist the Committee in establishing the compensation opportunities for executives in 2017.

The Committee continued to use a peer group of 18 banks as part of its evaluation. The peer group consists of eight banks with higher assets and ten banks with lower assets than Synovus, and does not include any banks with more than three times Synovus’ assets. As part of its evaluation of market practices, the Committee reviewed the most recent proxy data available for the banks listed below, as well as data appropriate to our industry

- 2018 Proxy Statement    37

EXECUTIVE COMPENSATION

and company size from external market surveys. When reviewing this data, the Committee focused on total direct compensation opportunities, not necessarily the amount of compensation actually paid, which varies depending upon each companies’ performance results.

Compensation Framework: Compensation Policies, Compensation Process and Risk Considerations

Compensation Policies

Stock Ownership/Retention Guidelines

To align the interests of its executives with shareholders, Synovus implemented stock ownership guidelines for its executives. Under the guidelines, executives are required to maintain ownership of Synovus common stock equal to at least a specified multiple of base salary, as set forth in the table below:

The guidelines are reviewed at the beginning of each calendar year. Executives have a five-year grace period to fully achieve the guideline with an interim three-year goal. Until the guideline is achieved, executives are required to retain all net shares received upon the exercise of stock options or vesting of other stock-based awards, excluding shares used to pay an option’s exercise price and any taxes due upon exercise or vesting of an award. In determining compliance, the guidelines allow consideration of any stock options or other stock-based awards granted to executives, including restricted stock units. In the event of a severe financial hardship, the guidelines permit the development of an alternative ownership plan by the Chairman of the Board of Directors and Chairman of the Committee.

All current executives were in compliance with the guidelines (with applicable grace periods) as of December 31, 2017.

Hold Until Retirement Provision

Synovus has also adopted a “hold until retirement” policy that applies to all unexercised stock options and unvested restricted stock and restricted stock unit awards. Under this policy, executives that have attained the stock ownership guidelines described above are also required to retain ownership of 50% of all stock acquired through Synovus’ equity compensation plans (after taxes and transaction costs) until their retirement or other termination of employment. The “hold until retirement” requirement further aligns the interests of our executives with shareholders.

Clawback Policy

The Compensation Committee approved a clawback policy on January 22, 2014, pursuant to which any incentive compensation paid to Synovus’ executive officers that is based upon materially inaccurate performance metrics or financial statements, or that results from any risk-related actions that result in or are reasonably expected to result in a material adverse impact to Synovus or a business unit, are subject to clawback at the Committee’s discretion.

Anti-Hedging Policy

Synovus does not allow directors or executive officers to hedge the value of Synovus equity securities held directly or indirectly by the director or executive officer. Synovus’ policy prohibits the purchase or sale of puts, calls, options or other derivative securities based on Synovus’ securities, as well as hedging or monetization transactions, such as zero-cost collars and forward sale contracts or other derivative securities based on Synovus securities.

Anti-Pledging Policy

Synovus’ Corporate Governance Guidelines and Insider Trading Policy prohibit pledges of our stock by directors and executive officers.

38		- 2018 Proxy Statement

EXECUTIVE COMPENSATION

Tax Considerations

Section 162(m) of the Internal Revenue Code of 1986, as amended, limits the deductibility of compensation paid by a publicly-traded corporation to certain named executive officers for amounts in excess of $1 million. Prior to the enactment of H.R. 1, formerly known as the Tax Cuts and Jobs Act of 2017, performance-based compensation that met certain conditions was exempt from the deduction limitation. The 2017 annual cash incentive opportunities and PSU and MRSU awards granted to our executive officers were initially designed in a manner intended to be exempt from the deduction limitation of Section 162(m) because they are paid based on the achievement of pre-determined performance goals established by the Compensation Committee pursuant to our shareholder-approved equity incentive plan.

The exemption from Section 162(m)’s deduction limit for performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our covered executive officers in excess of $1 million will not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.

Despite the Compensation Committee’s efforts to structure executive annual cash incentives and PSU and MRSU awards in a manner intended to be exempt from Section 162(m) and therefore not subject to its deduction limits, no assurance can be given that this compensation will satisfy the requirements for exemption due to uncertainties as to the application and interpretation of Section 162(m) and the transition relief. Further, the Compensation Committee reserves the right to modify compensation that was initially intended to be exempt from Section 162(m) if it believes the benefits of doing so outweigh the loss of a tax deduction.

Accounting Considerations

We account for all compensation paid in accordance with generally accepted accounting principles. The accounting treatment has generally not affected the form of compensation paid to named executive officers.

No Option Repricing

Our 2013 Omnibus Plan prohibits the repricing of stock options and stock appreciation rights without shareholder approval.

Timing of Equity Awards

If the Compensation Committee is taking action to approve equity awards on or near the date that Synovus’ annual earnings are released, the Committee has established the grant date for equity awards to executives as: (a) the last business day of the month in which earnings are released or, if later, (b) two complete business days following the date of the earnings release. This policy ensures that the annual earnings release has time to be absorbed by the market before equity awards are granted.

Compensation Process

Role of Compensation Committee and Compensation Consultant in Compensation Process

The roles of the Compensation Committee and its compensation consultant in the compensation process are described in detail beginning on page 9 of this Proxy Statement under “Corporate Governance and Board Matters—Committees of the Board—Compensation Committee.”

Role of the Executive Officers in the Compensation Process

Synovus’ Chief Executive Officer generally attends Compensation Committee meetings by invitation of the Committee. The Chief Executive Officer provides management perspective on issues under consideration by the Committee and makes proposals regarding the compensation of the named executive officers, other than himself. The Chief Executive Officer does not have authority to vote on Committee matters. The Committee regularly meets in executive session without any executive officers present. For more information regarding Committee meetings, please refer to page 9 of this Proxy Statement under “Corporate Governance and Board Matters—Committees of the Board—Compensation Committee.”

Tally Sheets

The Committee historically has used annual tally sheets to add up all components of compensation for the Chief Executive Officer (and for the other named executive officers on a less frequent basis), including base salary, bonus, long-term incentives, accumulative realized and unrealized stock options and restricted stock gains, the dollar value of perquisites and the total cost to the Company, and earnings and accumulated payment obligations under Synovus’ nonqualified deferred compensation program. Tally sheets also provide estimates of the amounts payable to each executive upon the occurrence of potential future events, such as a change of control, retirement, voluntary or involuntary termination, death and disability. Tally sheets are used to provide the Committee with total compensation amounts for each executive so that the Committee can determine whether the amounts are in line with our compensation strategy. The Committee reviewed tally sheets for the Chief Executive Officer and for Synovus’ other named executive officers in October 2017 and concluded that their total compensation is fair and reasonable.

Risk Considerations

Our compensation program is reviewed by several different groups to ensure that the risks involved with the program are appropriately assessed and managed. The compensation risks are first reviewed by the management team that designs, implements and administers the program. Incentive compensation programs are also reviewed by the Executive Risk Committee, a management committee chaired by our Chief Risk Officer. As a part of

- 2018 Proxy Statement    39

EXECUTIVE COMPENSATION

this process, management completes a thorough risk assessment for each plan, assessing the administrative, strategic and financial risk of each compensation plan, ensuring consistency in the review and administration of each plan and producing an overall risk assessment rating for each plan. Moreover, management reviews each plan for alignment with Synovus’ strategic objectives and assesses whether the payouts are equitable for value generated to Synovus and whether the plans encourage unnecessary risk-taking by Synovus’ participants. During 2017, the Committee requested that management formally document the Company’s process and procedures for assessing risk in our incentive compensation program. Management engaged an external advisor to assist with the Committee’s request. The documentation, including specific roles and responsibilities, regarding the Company’s risk assessment process were then reviewed with the Compensation Committee. In addition, in 2017, the Compensation Committee met with the Chief Risk Officer to review a risk assessment of our compensation plans.

Synovus’ employee incentive plans are broadly classified by business unit: incentive plans for Synovus’ banking divisions and incentive plans for Synovus’ Financial Management Services division. All of the plans were assessed for risk factors in different categories, including financial risks, strategic risks, and administrative risks. Each plan was assigned a level of risk ranking from “1” (highest risk) to “5” (lowest risk) for each risk category. Any plan that received a “1” or “2” in any category was modified through the implementation of additional controls to ensure appropriate mitigation of risks. After the implementation of such controls, no plans were ranked higher than a “3.” After reviewing the incentive plans and the Company’s risk assessment process, the Compensation Committee concluded that there were no unnecessary risks under the plans and there were no risks arising from the Company’s compensation policies and practices that were likely to have a material adverse effect on the Company.
