PROXY STATEMENT

FOR THE

ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON WEDNESDAY, MAY 15, 2019

TO OUR SHAREHOLDERS:

This proxy statement is being furnished to holders of the common stock of Southside Bancshares, Inc. (the “Company”) in connection with the Company’s 2019 Annual Meeting of Shareholders (the “Annual Meeting”) to be held on Wednesday, May 15, 2019, at 11:30 a.m., local time, at Willow Brook Country Club, 3205 West Erwin Street, Tyler, Texas 75702, and at any adjournments thereof, for the purpose of considering and acting upon the following:

This Proxy Statement and a proxy card, as well as the Annual Report of the Company for the year ended December 31, 2018, including financial statements, are first being sent or made available to shareholders on or about April 2, 2019.

You are encouraged to review all of the information contained in the proxy materials before voting.

VOTING OF PROXY

If your proxy is executed and returned, it will be voted as you direct. If no direction is provided, the proxy will be voted in accordance with the Board’s recommendations, as follows:


•	FOR the election of all of the nominees named in this proxy statement as directors;


•	FOR the approval of the compensation of the Company's named executive officers;


•	FOR the ratification of the appointment of EY.

The proxies will use their discretion with respect to voting on any other matters presented for a vote at the meeting. Additionally, if your proxy is executed and returned, it will be voted to approve the minutes of the last Annual Meeting. This vote will not amount to a ratification of any action taken at that meeting nor will it indicate approval or disapproval of that action.

If your shares are registered in your name as the shareholder of record, you may vote by mail, telephone or Internet by following the instructions below. Voting instructions also appear on your proxy card. If you grant a proxy by telephone or by Internet, please have your proxy card available.


•	To vote by mail, complete, sign, and return the enclosed proxy card in the envelope provided to: Proxy Services, c/o Computershare Investor Services, P.O. Box 505000, Louisville, Kentucky, 40233-5000.


•	To vote by telephone, call toll free 1-800-652-VOTE (8683) within the United States, U.S. territories and Canada any time on a touch tone telephone and follow the instructions provided by the recorded message. There is NO CHARGE to you for the call.


•	To vote by Internet, access the voting site at www.investorvote.com/SBSI, or scan the Quick Response code with your smart phone and follow the voting instructions set forth on the secure website.

The telephone and Internet voting procedures are designed to authenticate the shareholder's identity and to allow shareholders to vote their shares and confirm their voting instructions have been properly recorded. Shareholders who vote by telephone or Internet do not need to return the proxy card. Proxies submitted by telephone or Internet must be recorded by 11:59 p.m. Eastern time on May 14, 2019.

If you hold your shares in “street name” in a stock brokerage account or through a bank, trust or other nominee, the broker or other nominee is considered the record holder and you are the beneficial owner of the shares. Beneficial owners vote their street name shares by instructing their broker or other nominee how to vote using the voting instruction form provided by the broker or nominee. Brokers only have authority to vote in their discretion on “routine” matters if they do not receive voting instructions from the beneficial owner of the shares.

Please note that the proposal to elect directors and the advisory vote on the compensation of the Company's named executive officers (the “Say-on-Pay” vote) are not considered routine matters. Consequently, if you do not give your broker or nominee specific voting instructions with respect to such proposals, your street name shares will be treated as broker non-votes with respect to those proposals (see “Quorum, Voting Rights and Procedures” below) and will have no effect on the outcome of such proposals.

If you hold your shares in street name and want to vote in person at the Annual Meeting, you must obtain from your broker or nominee a legal proxy issued in your name giving you the right to vote the shares directly at the meeting. You will not be entitled to vote at the meeting unless you present such a proxy to the Company at that time.

REVOCABILITY OF PROXY

Your proxy may be revoked prior to the Annual Meeting by providing notice in writing to the Corporate Secretary at the Company’s principal executive office, located at 1201 South Beckham Avenue, Tyler, Texas 75701, at any time, or by advising the Corporate Secretary at the Annual Meeting that you wish to revoke your proxy and vote your shares in person. Your attendance at the Annual Meeting will not constitute automatic revocation of the proxy.

PERSONS MAKING THE SOLICITATION

The Company’s Board is soliciting the proxy. The expense of soliciting your proxy will be borne entirely by the Company and no other person or persons will bear such costs either directly or indirectly. Proxies will be solicited principally by mail, but may also be solicited by personal interview, telephone and email by directors, officers and employees of the Company who will receive no additional compensation.

RECORD DATE AND OUTSTANDING SHARES

The Company’s Board has fixed the close of business on March 21, 2019, as the record date for determining the holders of common stock of the Company entitled to notice of and to vote at the Annual Meeting. At the close of business on March 21, 2019, there were approximately 33,717,464 shares of common stock outstanding and eligible to be voted on each matter.

QUORUM, VOTING RIGHTS AND PROCEDURES

The approval of all proposals brought before the Annual Meeting requires a quorum be present at the Annual Meeting. The presence, in person or by properly submitted proxy, of the holders of a majority of the shares of common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum. In the event a quorum is not represented in person or by proxy at the Annual Meeting, a majority of shares present or represented at the meeting and entitled to vote at the meeting may adjourn the Annual Meeting to allow the solicitation of additional proxies or other measures to obtain a quorum.

Each shareholder is entitled to one vote on each proposal per share of common stock held as of the record date.

Proposal 1, the election of four directors to serve until the 2022 Annual Meeting, requires the affirmative vote of a majority of the votes cast by the holders of shares of common stock entitled to vote in the election of directors; provided, however, that if, as of the record date, the number of nominees for director exceeds the number of positions on the Board to be filled by election at such meeting, or a “contested election,” then the directors shall be elected by a plurality of the votes cast. A “majority of the votes cast” means that the number of shares cast “for” a director’s election exceeds the number of shares cast “against” a director’s election, with abstentions and broker non-votes counting as votes neither “for” nor “against” such director’s election. A “plurality of the votes cast” means that the director nominees who receive the highest number of “for” votes will be elected to the Board. The Board has proposed four nominees for election. No other nominees for election to the Board have been submitted for election in accordance with our bylaws. Thus, the Board has determined that this is not a contested election, and each director will be elected by a majority of the votes cast.

Under our bylaws, any incumbent director who is a nominee in an uncontested election who does not receive a majority of votes cast shall promptly tender his or her resignation to the Board, the effectiveness of which will be conditioned upon and subject to acceptance by the Board. The Nominating Committee will make a recommendation to the Board as to whether to accept or reject the tendered resignation or whether other action should be taken, after which the Board will vote to decide whether to accept the recommendation of the Nominating Committee and will promptly disclose that decision and the rationale behind its decision.

Proposal 2, the Say-on-Pay vote, and Proposal 3, the ratification of EY as the Company’s independent registered public accounting firm and any other matter that may properly come before the Annual Meeting, require approval by a majority of the shares of common stock entitled to vote on, and voted for or against, or expressly abstained from voting, with respect to the matter.

EFFECT OF WITHHOLD VOTES, ABSTENTIONS AND BROKER NON-VOTES

Shares represented at the Annual Meeting that are withheld or abstain from voting and broker non-votes votes (i.e., the submission of a proxy by a broker or nominee specifically indicating the lack of discretionary authority to vote on the matter) will be considered present for the purpose of determining a quorum at the Annual Meeting.

For Proposal 1, abstentions and broker non-votes will not be counted in determining whether a director has received a majority of the votes cast for his or her election.

For Proposals 2 and 3 and for any other matter that may properly come before the meeting, abstentions will be included in vote totals and, as such, will have the same effect on those proposals as a vote against such proposals. Broker non-votes will not be included in vote totals and, as such, will have no effect on such proposals.

ELECTION OF DIRECTORS

(PROPOSAL 1)

The Board is currently comprised of 17 directors. The Board size will be reduced to 15 directors effective as of the date of the Annual Meeting as one director has elected not to stand for re-election at the Annual Meeting and one director has elected to retire effective as of the date of the Annual Meeting. The Board is classified into three classes, two of which are currently comprised of six directors and one that is currently comprised of five directors. Following the Annual Meeting, we will continue to have three classes, one of which will be comprised of six directors, one of which will have five directors and one of which will have four directors. One class of directors is elected each year for a three-year term. Under NASDAQ listing rules, a majority of the Board must be comprised of independent directors. The Board has determined that each director nominated is independent under NASDAQ listing rules except for Lee R. Gibson, President and Chief Executive Officer.

The four individuals identified below are nominees for election at the Annual Meeting for a three-year term expiring at the 2022 Annual Meeting.

Term Expiring 2022


•	Michael J. Bosworth


•	Lee R. Gibson, CPA


•	George H. (Trey) Henderson, III


•	Donald W. Thedford

All of the nominees are currently directors of the Company and its subsidiary, Southside Bank. All of the nominees except George H. (Trey) Henderson, III were previously elected to the Board by shareholders. Mr. Henderson was appointed by the Board as a director of the Company during the fourth quarter of 2018. For biographical information on the nominees, please see “Information About Our Directors, Nominees and Executive Officers.”

Unless otherwise instructed, proxies received in response to this solicitation will be voted in favor of the election of the persons recommended by the Nominating Committee and nominated by the Board as nominees for directors of the Company. While it is not expected that any of the nominees will be unable to qualify or accept office, if for any reason one or more shall be unable to do so, the proxies will be voted for the substitute nominee(s) selected by the Board.

The Board recommends a vote FOR the election of each of the individuals nominated for election as a director.

CORPORATE GOVERNANCE

Board Leadership Structure

Our Board functions in a collaborative fashion that emphasizes active participation by all of its members. Our business is conducted day-to-day by our officers, under the direction of our CEO, Lee R. Gibson, with oversight from the Board, to enhance the long-term value of the Company for its shareholders. Mr. Gibson also serves as a member of the Board, which enables him to communicate the Board's strategic findings and guidance to management. Our Board determines who to appoint as our Chairman based on the knowledge and experience of the people then serving on our Board and chooses the person whom it believes best meets the needs of the Company. Based on these factors in 2018, the Board selected John R. (Bob) Garrett to serve as Chairman effective immediately following the 2018 Annual Meeting. Mr. Garrett previously served as Vice Chairman from January 1, 2015 until his selection as Chairman. Mr. Garrett has served on various board committees for the Company and for Southside Bank and has proven to be an integral part of the Board since his election in 2009. The Board selected Donald W. Thedford to serve as Vice Chairman effective immediately following the 2018 Annual Meeting. Mr. Thedford has been on the Board since 2009 and has served on various board committees for both the Company and Southside Bank. Both the Chairman and the Vice Chairman are independent directors and serve as ex-officio nonvoting members of the Audit, Nominating, Compensation, Risk and Information Technology, Digital Banking and Innovation Committees.

Board Oversight of Risk

The Board recognizes that, although day-to-day risk management is primarily the responsibility of the Company’s management team, the Board plays a critical role in the oversight of risk. The Board believes an important part of its responsibility is to assess the major risks the Company faces and review the Company’s options for monitoring and controlling these risks. The Board assumes responsibility for the Company’s overall risk assessment, primarily through the Board's Audit and Risk Committees. The Audit Committee has specific responsibility for oversight of risks associated with financial accounting and audits, as well as internal control over financial reporting. This includes the Company’s risk assessment and management policies, the Company’s major financial risk exposure and the steps taken by management to monitor and mitigate such exposure. The Risk Committee assists the Board in fulfilling its responsibility for overseeing and improving the Company's enterprise-wide risk management practices, which includes overseeing that the executive team has identified and assessed the key risks the Company faces and has established a risk management infrastructure capable of addressing those risks. The Compensation Committee oversees the risks relating to the Company’s compensation policies and practices, as well as management development and leadership succession, in the Company’s various business units. The Information Technology, Digital Banking and Innovation Committee is responsible for the oversight of technology risk, which includes cybersecurity. The Board as a whole examines specific business risks including but not limited to credit risk, interest rate risk and operations risk, in its regular strategic reviews on a Company-wide basis.

In addition to periodic reports from the Audit, Risk, Compensation and Information Technology, Digital Banking and Innovation Committees about the risks over which they have oversight, the Board receives presentations throughout the year from management that include discussions of significant risks specific to the Company and the banking industry. Periodically, at Board meetings, management discusses matters of particular importance or concern, including any significant areas of risk requiring Board attention. We believe our risk oversight structure is also supported by our current Board leadership structure, with the Chairman of the Board working together with the independent Audit Committee and other standing committees.

Independent Directors

The Company’s common stock is listed on the NASDAQ Global Select Market under the symbol “SBSI.” NASDAQ listing rules require a majority of our directors to be “independent directors,” as defined in the NASDAQ listing rules. The Board has affirmatively determined that all of the Company’s directors, other than Lee R. Gibson and H. J. Shands, III, are independent directors under the NASDAQ listing rules. Each member of the Board’s Audit, Nominating and Compensation Committees qualifies as an independent director, and all other Board committees are comprised of a majority of independent directors. All Board committees are chaired by independent directors.

Shareholder Communication with the Board of Directors

The Company has adopted a procedure by which shareholders may send communications to one or more members of the Board by writing to such director(s) or to the Board as a whole in care of the Corporate Secretary, Southside Bancshares, Inc., 1201 South Beckham Avenue, Tyler, Texas 75701. Any such communications will be promptly distributed by the Corporate Secretary to such individual director(s) or to all directors if addressed to the Board as a whole.

Code of Ethics

The Company has adopted a Code of Ethics applicable to all directors and executive officers of the Company. The Code of Ethics is available on the Company’s website, http://investors.southside.com, under the topic Governance Documents. Within the time period required by the Securities and Exchange Commission (“SEC”) and the NASDAQ Global Select Market, we will post on our website any amendment to our Code of Ethics and any waiver applicable to any of our directors, executive officers or senior financial officers. We include our website address throughout this filing only as textual references. The information contained on our website is not incorporated in this proxy statement by reference.

Procedures for Reporting Concerns about Accounting, Internal Accounting Controls or Auditing Matters

Management of the Company has established a Whistle Blower Policy. This includes an online reporting system as well as a toll-free, 24-hour, seven-day-a-week fraud hotline. This is a confidential service by which officers and employees can report to an independent company any questionable accounting or auditing matters, including, but not limited to, the following: fraud or deliberate error in the preparation, evaluation, review or audit of any financial statement of the Company; fraud or deliberate error in the recording and maintaining of financial records of the

Company; deficiencies in or noncompliance with the Company’s internal accounting controls; misrepresentation or false statement to or by a senior officer or accountant regarding a matter contained in the financial records, financial reports or audit reports of the Company; or deviation from full and fair reporting of the Company’s financial condition. Any complaints received by the independent company will be reported directly to the Chairman of the Audit Committee and to the Chief Audit Executive of the Company. Complaints will be reviewed by Internal Audit under the direction of the Audit Committee. Complaints submitted will be promptly investigated and appropriate corrective action will be taken, as warranted by the investigation. Management is committed to complying with all applicable securities laws and regulations and, therefore, encourages officers and employees to raise concerns regarding any suspected violations of those standards by using the fraud hotline.

Anti-Hedging and Anti-Pledging Policy

The Company maintains an anti-hedging and anti-pledging policy, which prohibits executive officers, directors and employees who receive equity grants from (1) directly or indirectly engaging in any hedging or monetization transactions, such as exchange funds, prepaid variable forward contracts, equity swaps, puts, calls, collars, forward sale contracts and other derivative instruments, through transactions in the Company’s securities or through the use of financial instruments designed for such purpose, (2) engaging in short sale transactions in the Company’s securities or (3) pledging the Company’s securities as collateral for a loan, including through the use of traditional margin accounts with a broker. The Company maintains this policy because hedging transactions, which might be considered short-term bets on the price of the Company’s securities, could create the appearance that the person is trading based on inside information. In addition, transactions in options may also focus the person’s attention on short-term performance at the expense of the Company's long-term objectives. Finally, the Company maintains this policy because a margin sale or foreclosure sale may occur at a time when the pledger is aware of material nonpublic information or otherwise is not permitted to trade in the Company’s securities and the margin sale or foreclosure sale of the Company’s securities during such time could also create the appearance that the person is trading based on inside information.

Board of Directors Meeting Attendance

The Board of Directors and its committees held the following number of meetings during the fiscal year ended December 31, 2018:



		Number of Meetings Held in 2018
Board		19
Audit Committee		16

During 2018, each of our directors attended at least 75% of the aggregate of (1) the total number of meetings of the Board (held during the period for which he or she served as a director) and (2) the total number of meetings held by all committees of the Board on which he or she served (during the periods that he or she served). All of the Company’s directors were in attendance at the Company’s 2018 Annual Meeting except Joe Norton, who retired upon the expiration of his term at the 2018 Annual Meeting. Although the Company has not adopted a formal written policy with respect to director attendance at meetings, we encourage our directors to attend each annual meeting of shareholders and all meetings of the Board and committees on which the directors serve.

COMMITTEES OF THE COMPANY

Audit Committee of Southside Bancshares, Inc.

The Audit Committee of the Board was established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and consists of six directors, Melvin B. Lovelady, CPA (Chairman), S. Elaine Anderson, CPA, Alton Cade, Tony K. Morgan, CPA, William Sheehy and Preston L. Smith. Each member of the Audit Committee is an independent director as defined by the current NASDAQ listing rules and applicable SEC rules and each of whom is also a director of Southside Bank. In addition, the Nominating Committee of the Board has unanimously determined that S. Elaine Anderson, CPA, Melvin B. Lovelady, CPA, and Tony K. Morgan, CPA, each qualify as an “audit committee financial expert” as defined by the SEC. The Nominating Committee of the Board has also unanimously determined that all Audit Committee members are financially literate under the current NASDAQ listing rules.

The Audit Committee is primarily responsible for the engagement of the independent registered public accounting firm, oversight of the Company’s financial statements and controls, assessing and ensuring the independence, qualifications and performances of the independent registered public accounting firm, approving the services and fees of the independent registered public accounting firm and reviewing and approving the annual audited financial statements of the Company before issuance, subject to the approval of the Board. The Audit Committee manages the Company’s relationship with its independent registered public accounting firm, who report directly to the Audit Committee. The Audit Committee also monitors the internal audit function, internal accounting procedures and assures compliance with all appropriate statutes and regulations. The Audit Committee has the authority to obtain advice and assistance from outside legal, accounting or other advisors as the Audit Committee deems necessary to carry out its duties, with funding from the Company for such advice and assistance. No members of the Audit Committee received any compensation from the Company during the last fiscal year other than directors’ fees. The Audit Committee met 16 times during 2018.

Audit Committee Charter

The Board has adopted a formal written Audit Committee charter that outlines the purpose of the Audit Committee, sets forth the membership requirements and addresses the key responsibilities of the Audit Committee. A copy of the Audit Committee charter may be obtained at the Company’s website, http://investors.southside.com, under the topic Governance Documents.

Nominating Committee of Southside Bancshares, Inc.

The Nominating Committee is responsible for identifying, screening and recommending candidates for election to the Board. During 2018, the Committee was comprised of Preston L. Smith (Chairman), Herbert C. Buie, Melvin B. Lovelady, CPA, John F. Sammons, Jr. and William Sheehy, each of whom is an independent director of the Company, as defined by the current NASDAQ listing rules, and each of whom is also a director of Southside Bank. The Nominating Committee met three times in 2018.

Effective March 1, 2019, the Nominating Committee consists of Preston L. Smith (Chairman), Lawrence Anderson, M.D., Herbert C. Buie, Patricia A. Callan and John F. Sammons, Jr., each of whom is an independent director of the Company, as defined by the current NASDAQ listing rules, and a director of Southside Bank.

The Nominating Committee seeks to create a Board that is, as a whole, strong in its collective knowledge and diversity of skills and experience and background with respect to accounting and finance, management and leadership, business judgment, industry knowledge and corporate governance. When the Nominating Committee reviews a potential new candidate, it looks specifically at the candidate’s qualifications in light of the needs of the Board and the Company at that time, given the then-current mix of director attributes.

The Company’s Board of Directors has established the following process for the identification and selection of candidates for director. The Nominating Committee, in consultation with the Chairman of the Board, annually reviews the appropriate experience, skills and characteristics required of Board members in the context of the current membership of the Board to determine whether the Board would be better enhanced by the addition of one or more directors. In considering board of director candidates, the Nominating Committee takes into consideration all factors that it deems appropriate, including, but not limited to, the individual’s character, education, experience, knowledge, skills and ownership of the Company’s stock. The Nominating Committee will also consider the extent of the individual’s experience in business, education or public service, his or her ability to bring a desired range of skills, diverse perspectives and experience to the Board and whether the individual possesses high ethical standards, a strong sense of professionalism and is capable of serving the interests of the Company's shareholders. A candidate should possess a working knowledge of the Company’s current local market areas. Additionally, the Nominating Committee will consider the number of boards the candidate currently serves on when assessing whether the candidate has the appropriate amount of time to devote to serving on the Company’s Board. The Nominating Committee, when considering diversity, gives strong consideration to a wide range of diversity factors as a matter of practice when evaluating candidates to the Board and incumbent directors, but the Committee does not have a formal policy regarding Board diversity.

The Nominating Committee identifies candidates to the Board by introduction from management, members of the Board, employees or other sources, and shareholders that satisfy the Company’s policy regarding shareholder recommended candidates. The Nominating Committee does not evaluate director candidates recommended by shareholders differently than director candidates recommended by other sources. Shareholders wishing to submit director candidate recommendations for the 2020 Annual Meeting should write to the Nominating Committee in care of the Corporate Secretary, Southside Bancshares, Inc., Post Office Box 8444, Tyler, Texas 75711. Any such shareholder must follow the procedures set forth in the Company’s bylaws and the Nominating Committee charter. Our bylaws provide that proposals that comply with all rules and requirements of the SEC and are included in our proxy statement are deemed to comply with the advance notice procedures in our bylaws. Recommendations must be submitted to the Corporate Secretary on or before December 4, 2019, in order to be included in the proxy statement for the 2020 Annual Meeting. See “Shareholder Proposals.” The Nominating Committee is not obligated to recommend any individual as a

nominee for election to the Board. No shareholder recommendations have been received by the Company for this Annual Meeting. Accordingly, no rejections or refusals of such candidates have been made by the Company.

In addition, the Nominating Committee is responsible for identifying, screening and recommending to the Board candidates to serve on the Compensation Committee, Audit Committee, Risk Committee and Information Technology, Digital Banking and Innovation Committee. These recommendations are submitted to the Board for final approval.

DIRECTOR STOCK OWNERSHIP POLICY

To help promote the alignment of the personal interests of the Company’s directors with the interests of our shareholders, in February 2014 the Company established a stock ownership policy for all non-employee directors. Under this policy, each non-employee director is required to own at least 5,000 shares of the Company’s common stock within five years after the date he or she is first elected as a director and maintain such ownership while serving on the Board. For new directors, the acquisition period is measured using the calendar year, with the director's five-year accumulation period beginning on January 1 of the year following their election. For directors elected prior to February 2014, the policy requires the acquisition of shares over five years by January 1, 2019. To the extent a director is not in compliance with the policy after the five-year accumulation period, any compensation paid to that director must be in the form of stock compensation and the director is required to retain 50% of these stock awards. As of March 21, 2019, all non-employee directors met the ownership requirement.

COMPENSATION DISCUSSION AND ANALYSIS

Overview of Compensation Program

In the paragraphs that follow, we will give an overview and analysis of our compensation programs and policies, the material compensation decisions we have made under those programs and policies, and the material factors that we considered in making those decisions. Later in this proxy statement under the heading “Executive Compensation” you will find a series of tables containing specific information about the compensation earned or paid in 2018 to the following executive officers, who are referred to as the “named executive officers” or “NEOs.”


•	Lee R. Gibson, CPA - President, Chief Executive Officer and Director of the Company and Southside Bank;


•	Julie N. Shamburger, CPA - Senior Executive Vice President and Chief Financial Officer of the Company and Southside Bank and advisory director of Southside Bank;


•	Tim Alexander - Chief Lending Officer of the Company and Southside Bank and advisory director of Southside Bank;


•	Brian K. McCabe - Senior Executive Vice President and Chief Operations Officer of the Company and Southside Bank and advisory director of Southside Bank;


•	H. J. Shands, III - Regional President, East Texas and Director of the Company and Southside Bank.

The Compensation Committee of the Board (the “Committee”) has responsibility for reviewing and establishing the Company’s compensation programs, consistent with the Company’s compensation philosophy. The Committee attempts to ensure the total compensation paid to the NEOs is fair, reasonable, and competitive. The Committee conducts an annual base salary and bonus compensation level review of the NEOs and occasionally engages outside consultants, as discussed below. When determining compensation, the Committee typically does not establish specific performance goals for the NEOs, but instead evaluates and reviews each NEO’s contribution to the overall performance of the Company, taking into account any changes in duties or responsibilities, the overall banking environment, skills and talents demonstrated during the year and leadership.

During 2018, the Committee reviewed with management the design and operation of the incentive compensation arrangements for the NEOs and other employees of Southside Bank for the purpose of determining whether such programs might encourage inappropriate risk-taking that could have a material adverse effect on the Company. The Committee concluded the incentive plans and policies do not encourage the NEOs or other employees to take risks that are reasonably likely to have a material adverse effect on the long-term well-being of the Company.

The Committee also reviews and develops recommendations for director compensation, including committee service fees.

Compensation Philosophy and Objectives

The Committee believes the most effective executive compensation program is one that is designed to reward long-term and strategic performance and which aligns executives’ interests with those of the shareholders, with the ultimate objective of improving long-term shareholder value. The Committee evaluates both performance and compensation to ensure the Company maintains its ability to attract and retain superior officers in key positions and that compensation provided to key officers remains competitive relative to the compensation paid to similarly situated executives of our peer companies (as discussed below). To that end, the Committee believes executive compensation provided by the Company to its NEOs should include both cash and other benefits that reward both Company and executive performance. Performance is evaluated in a number of ways. First and most importantly, the Committee evaluates the overall performance of the Company during the year and over a longer term, typically three years. Performance metrics evaluated include profitability, return on equity, ability to pay dividends to shareholders, overall asset quality, capital levels and earnings per share. The Company’s performance is measured against its peers utilizing outside independently produced peer group data. The Committee also takes into consideration the results of outside examinations and audits. The Committee evaluates individual

performance of each NEO in their areas of responsibility and to the Company as a whole, taking into consideration the overall banking environment. Using this information as a guide the Committee then works through its process of evaluating and setting compensation.

Role of Executive Officers in Compensation Decisions

The Committee makes recommendations to the Board regarding all compensation decisions for the NEOs. The CEO provides input regarding the performance of the other NEOs and makes recommendations for compensation amounts payable to the other NEOs. These recommendations are based on the CEO’s personal observation of each NEO's performance, commitment and contribution to the Company. The CEO is not involved with any aspect of determining his own pay.

Setting Executive Compensation

Based on the compensation objectives noted above, the Committee has structured the NEOs’ annual compensation to be competitive and to motivate and reward the NEOs for their performance.

In furtherance of this, the Committee occasionally engages an outside consulting firm to conduct a peer review of its overall compensation program for the NEOs. In 2017, the Committee engaged Pearl Meyer & Partners (“PM&P”) to serve as an independent outside consultant to Southside Bancshares, Inc., reporting directly to the Committee. PM&P provided the Committee a letter with a statement of independence and the procedures they follow to remain independent. PM&P was engaged to prepare an Executive Compensation Review, specifically for the Committee, which was provided in September 2017. This Executive Compensation Review was based on a custom peer group selected by PM&P based on asset size, location and performance (the “Compensation Peer Group”). The Compensation Peer Group is comprised of sixteen public commercial banks in Texas, Oklahoma, Arkansas, Alabama, Colorado, Georgia, Iowa, Mississippi, Missouri and South Carolina against which PM&P and the Committee believe the Company competes for talent. At the time of the study, the Compensation Peer Group assets ranged from $4.0 billion to $8.9 billion with a median asset size of approximately $6.6 billion. The companies comprising the Compensation Peer Group were:



Ameris Bancorp	Independent Bank Group, Inc.
BancFirst Corporation	LegacyTexas Financial Group, Inc.
Enterprise Financial Services Corp	National Bank Holdings Corporation
Fidelity Southern Corporation	Renasant Corporation
First Financial Bankshares, Inc.	ServisFirst Bancshares, Inc.
Great Southern Bancorp, Inc.	Simmons First National Corporation
Green Bancorp	South State Corporation
Heartland Financial USA, Inc.	State Bank Financial Corporation

During Committee discussions regarding setting NEO compensation for 2018, the Committee referenced the 2017 Executive Compensation Review performed by PM&P. The Compensation Peer Group data is used for comparative purposes only. We do not target executive officer pay opportunities at any particular percentile relative to our Compensation Peer Group. The Committee evaluates the NEO's compensation and reviews and discusses performance, job responsibilities and tenure for each NEO position. Based on this review and discussion of each NEO, the Committee determines the NEO's total compensation. There is no pre-established policy or target for the allocation among different types of compensation. In determining the appropriate mix of compensation for 2018, the Committee took into consideration that equity-based compensation would be part of its executive officer compensation program for 2018.

2018 In Review

Southside Bancshares, Inc. financial results for 2018 included a return on average shareholders' equity of 9.87%, and a return on average assets of 1.19%. Net income for 2018 increased $19.8 million, or 36.5%, and diluted earnings per common share increased $0.30, or 16.6%. During 2018, loans increased $18.4 million and nonperforming assets increased to 0.70% of total assets.

2018 Executive Compensation Components

For the fiscal year ended December 31, 2018, the principal components of compensation for NEOs were:


•	Base salary;


•	Annual incentive program;


•	Discretionary bonus;


•	Long-term equity incentive awards;


•	Retirement benefits;


•	Perquisites and other personal benefits; and


•	Health and welfare benefits.

Base Salary

The Company provides NEOs and other employees with a base salary to compensate them for services rendered during the fiscal year. Base salaries for NEOs are determined based on their position and responsibility by using comparable market data adjusted for duties and responsibilities.

During the review of base salaries for executives, the Committee primarily considers:


•	Compensation Peer Group data;


•	internal review of the executive’s compensation, both individually and relative to other officers;


•	overall individual performance of the executive;


•	scope of responsibilities;


•	experience; and


•	tenure with the Company.

Salary levels are typically considered annually as part of the Company’s performance review process, as well as upon a promotion or other change in job responsibility. Merit-based increases to salaries of NEOs are based on the Committee’s assessment of performance after considering recommendations of the CEO (other than with respect to himself). The NEO salaries for 2018 were approved by the Committee based on the CEO’s recommendations for the other NEOs and company performance.

After considering all of the relevant factors and the performance of each executive, the Committee decided that Lee R. Gibson and Julie N. Shamburger would receive a 5.0% and 6.3% increase in base salary for 2018, respectively. Tim Alexander and Brian K. McCabe received a 3.1% and 9.1% increase in base salary for 2018, respectively. There was no change in base salary in 2018 for H. J. Shands, III, who became an officer of the Company in connection with the acquisition of Diboll State Bancshares (“Diboll”) effective November, 30, 2017.

Annual Incentive Program

The Company maintains a performance-based annual incentive bonus program, the Annual Incentive Program (“AIP”) for its most senior executive officers.

Participants in the program for 2018 were Lee R. Gibson, Julie N. Shamburger, Tim Alexander and Brian K. McCabe who had a maximum incentive opportunity equal to 50%, 40%, 40% and 30% of their base salary, respectively.

We believe a significant amount of executive compensation should be contingent on Company performance. The AIP formalizes this philosophy for our top executives by providing a cash incentive for the attainment of profitable growth and stable financial operating conditions.

For 2018, the Committee approved the following performance measures, all of which are weighted equally:


•	Earnings per share (“EPS”) growth (fully-diluted);


•	Loan growth;


•	Return on average equity (“ROAE”);


•	Efficiency ratio; and


•	Non-performing assets (“NPA”) as a percentage of total assets.

We believe a focus on these metrics over time will support sustained performance and the long-term creation and preservation of shareholder value.

Performance measures, goals and weighting are set annually by the Committee. In determining the amount of the annual incentive payment, a threshold level of performance is established for each measure. Participants will earn a cash award based on the amount by which actual performance exceeds the threshold goal as set forth below, up to the set percentage of bonus allocated to each performance measure. In the event the Company's performance is less than the threshold with respect to a particular performance measure, no incentive compensation is payable for that particular measure.



Performance Measure	Weighting	Threshold	Award for Achieving Performance Compared to Threshold
Performance Measure	Weighting	Threshold	Award for Achieving Performance Compared to Threshold
EPS Growth (Fully-Diluted)	20%	5.0%	2.5% for each 1% above the threshold
Loan Growth	20%	5.0%	2% for each 1% above the threshold
ROAE	20%	8.0%	2.5% for each 1% above the threshold
Efficiency Ratio	20%	58.0%	2% for each 1% below the threshold
NPAs / Assets	20%	0.50%	1.5% for each 0.01% below the threshold

The following table presents the actual performance results for 2018 compared to the thresholds for the performance measures and the resulting Annual Incentive Program percentage earned for 2018.



Performance Measure	2017 Result		2018 Result			2018 Growth		Compared to Threshold		Award		Maximum Award Weighting
EPS Growth (Fully-Diluted)	$	1.81	$	2.11		16.57	%	11.57	%	28.94	%	20.00	%
Loan Growth	$	3,294,356	$	3,312,799		0.56	%	(4.44	)%	—		—
ROAE			9.87		%			1.87	%	4.68	%	4.68	%
Efficiency Ratio			49.98		%			8.02	%	16.04	%	16.04	%
NPAs / Assets			0.70		%			(0.20	)%	—		—
Annual Incentive Earned												40.72	%

Based on these results, Mr. Gibson, Ms. Shamburger, Mr. Alexander and Mr. McCabe each earned 40.72% of their maximum annual incentive opportunity for 2018, or $131,459, $55,372, $81,430 and $36,644 respectively.

Discretionary Bonus

In addition to the AIP, the Board from time to time may determine that it is appropriate to pay a NEO a discretionary bonus as a reward based on overall Company performance or individual contributions, but not tied to achievement of specific performance numbers. Lee R. Gibson, Julie N. Shamburger, Tim Alexander, Brian K. McCabe and H. J. Shands, III received discretionary bonuses for 2018 in the amounts of $50,000, $30,000, $10,000, $20,000 and $115,000, respectively for their individual contributions, leadership and performance during 2018.

Long-Term Equity Incentive Awards

The Southside Bancshares, Inc. 2017 Incentive Plan (the “2017 Incentive Plan”) provides for the grant of equity awards to our employees, officers and directors. The primary purpose of the 2017 Incentive Plan is to promote our success by linking the personal interests of our employees, officers, directors and consultants to those of our shareholders, and by providing participants with an incentive for outstanding performance. The 2017 Incentive Plan outlines the type of incentive awards to be granted under the plan. In 2017, the Committee engaged the services of PM&P to assist in guiding the Committee as to what is comparable and customary relative to the Compensation Peer Group with respect to long-term equity programs.

In 2018, our NEOs were awarded long-term equity awards having a grant date fair value equal to their base salaries as follows: Lee R. Gibson, 50%; Tim Alexander, 35%, Julie N. Shamburger, 35%, Brian K. McCabe, 30% and H. J. Shands, III, 25%. These awards were granted 50% in the form of stock options and 50% in the form of restricted stock units (“RSUs”), based on grant date fair value. Details of the equity awards granted to the NEOs are set forth in the 2018 Grants of Plan-Based Awards Table below. We anticipate additional grants will be made during 2019.

Executive Stock Ownership Policy

The Company maintains a stock ownership policy that determines the amount of common stock that should be held by the Company’s executive officers. The policy specifies the value of Company stock (the “Required Market Value”), as a multiple of the executive officer’s base salary in effect as of the time the executive first becomes subject to the policy, which must be held by each executive officer, as follows:



	Position		Multiple
	Chief Executive Officer		3x Base Salary
	Chief Financial Officer		2x Base Salary
	Chief Lending Officer		2x Base Salary
	Other Executive Officers		One-half Base Salary

The CEO, CFO and CLO are strongly encouraged to achieve ownership of a sufficient number of shares to satisfy the Required Market Value within five years of first becoming subject to the policy, and other executive officers are strongly encouraged to comply with the policy within seven years of first becoming subject to the policy.

In order to meet the stock ownership requirement, an executive officer may count all shares of common stock owned by the executive (including shares held in the Company’s 401(k) Plan (the “401(k) Plan”), Employee Stock Ownership Plan (“ESOP”), shares held in an IRA and shares beneficially owned through a trust) and outstanding RSUs, but excluding shares underlying unexercised stock options.

Once an executive officer has obtained shares having a value equal or greater to the Required Market Value, the executive’s ownership requirement is converted into a number of shares determined by dividing the Required Market Value by the then-current stock price (the “Required Share Level”). Once an executive’s Required Share Level is determined, he or she must continue to beneficially own at least that number of shares in order to be in compliance with the policy. An executive’s Required Market Value and Required Share Level will be recalculated in connection with a salary increase relating to a change in title, but otherwise will not change as a result of changes in base salary or fluctuations in the price of the Company’s stock.

Executive officers who are not in compliance with the policy after the applicable five or seven year period are required to retain 50% of the shares received upon exercise or conversion of equity incentive awards.

The following table shows for each NEO the number of shares deemed held under the policy and the percentage of the ownership requirement they have reached.



	Stock Ownership at	Stock Held as a % of
Name	March 21, 2019	Ownership Requirement
Lee R. Gibson	57,491	98.2%
Julie N. Shamburger	28,080	>100%
Tim Alexander	25,147	>100%
Brian K. McCabe	33,256	>100%
H. J. Shands, III	294,472	>100%

Retirement Benefits

Retirement benefits fulfill an important role within the Company’s overall executive compensation program because they provide a financial security component which promotes retention. We place great value on the long-term commitment that many of our employees and the NEOs have made to us and aim to incent those individuals to remain with the Company and to act in a manner that will provide longer-term benefits to the Company. The Company believes its retirement program is comparable to those offered by the banks in our Compensation Peer Group and, as a result, is needed to ensure that our executive compensation remains competitive.

Our retirement plans are designed to encourage employees to take an active role in planning, saving and investing for retirement. The Company maintains a 401(k) Plan, a tax-qualified defined contribution plan in which substantially all of our employees, including the NEOs, are eligible to participate. The Company also maintains a tax-qualified defined benefit pension plan (the “Pension Plan”) pursuant to which participants are entitled to benefits based on final average monthly compensation and years of credited service. In addition, the Company maintains a non-qualified supplemental retirement plan (the “Restoration Plan”) which provides benefits in addition to the Pension Plan. The Pension Plan and the Restoration Plan are described in more detail under the Pension Benefits Table in this proxy statement.

The Company has entered into deferred compensation agreements with each of the NEOs, with the exception of H. J. Shands, III, that provide for the payment of a stated amount over a specific period of years. These deferred compensation agreements are described in more detail under the Pension Benefits Table in this proxy statement.

The Company has also entered into a split dollar agreement with Lee R. Gibson which allows the executive to designate the beneficiaries of death benefits under a life insurance policy. This agreement is described in more detail under the Summary Compensation Table in this proxy statement.

Perquisites and Other Personal Benefits

The Company provides NEOs with perquisites and other personal benefits the Company and the Committee believe are reasonable and consistent with its overall compensation program to better enable the Company to attract and retain superior employees for key positions. The Committee periodically reviews the levels of perquisites and other personal benefits provided to NEOs. The Committee did not review perquisites during 2018, and there were no changes in the types of perquisites provided in 2018. Perquisites provided to NEOs during 2018 were Company paid club dues for each NEO and a Company provided automobile for Lee R. Gibson, Julie N. Shamburger and Tim Alexander. Club memberships are made available to various officers who are expected to routinely entertain customers or prospective customers.

Health and Welfare Benefits

The Company offers a standard range of health and welfare benefits on a uniform basis and subject to insurance policy limitations to employees, including NEOs, and their eligible dependents. The benefits are designed to attract and retain employees and provide security to employees for their health and welfare needs. The benefits include: medical, prescription, dental, vision, employee life, group life, health savings accounts and flexible spending accounts. NEOs participate in these employee benefit plans, which are generally available to full-time employees on the same terms as a similarly situated employee. Another benefit available to officers at or above the Vice President level and meeting a service requirement is a bank-provided long-term disability insurance policy which includes accidental death and travel insurance plans and programs.

Key Employee Retention Compensation

The Company entered into a Key Employee Retention Agreement with H. J. Shands, III on June 12, 2017, in conjunction with the acquisition of Diboll. The agreement provides for a grant of equity awards, which vest over four years, as well as three retention payments, beginning 90 days after the merger effective date and ending at the second anniversary date.

For a further discussion of retention payments, please see the discussion of the Key Employee Retention Agreement in this proxy statement.

Severance

The Company entered into Employee Agreements with Lee R. Gibson in October 2007, Julie N. Shamburger in June 2008 and Brian K. McCabe in November 2008. The Board determined that it was in the best interest of the Company to retain the services and encourage the continued attention and dedication of these executives to their assigned duties. The severance and change in control termination amounts were negotiated based on the NEO's tenure, scope of responsibilities and other provisions in the agreement.

For a further discussion of severance payments, please see the terms of the Employment Agreements in this proxy statement.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code places a limit of $1 million on the amount of compensation that we may deduct in any year with respect to any one of our NEOs. Prior to 2018, the limitation did not apply to compensation that met the requirements under Section 162(m) for “qualifying performance-based” compensation. The exemption from Code Section 162(m)'s deduction limit for performance-based compensation, was 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 written arrangements in place as of November 2, 2017.

The Committee intends to maximize deductibility of executive compensation while retaining discretion needed to compensate executives in a manner commensurate with performance and the competitive landscape for executive talent.

EXECUTIVE COMPENSATION

The following table sets forth the compensation earned by or paid to each of the NEOs for the fiscal years ended December 31, 2018, 2017 and 2016. This information relates to compensation paid to the NEO's by Southside Bank, as the Company does not directly pay compensation to the NEOs.

CEO Pay Ratio Disclosure

The CEO pay ratio figures below are a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Exchange Act.

We determined that as of December 31, 2018, our total number of active U.S. employees was 924. To determine our median employee pay, we chose gross compensation as our consistently applied compensation measure. We then annualized base salary for those employees who commenced work during 2018 and any employees who were on leave for a portion of 2018. For hourly employees, we used a reasonable estimate of hours worked to determine annual base pay.

Using this methodology, we identified the median employee and that person's total annual compensation was $40,504. The total annual compensation of our CEO was $1,587,326. Accordingly, the ratio of CEO pay to median employee pay was 39:1.

Employment Agreements

The Company maintains employment agreements with Lee R. Gibson, Julie N. Shamburger, and Brian K. McCabe (the “Employment Agreements”). The Employment Agreement with Mr. Gibson was entered into as of October 22, 2007, and had an initial term through October 22, 2010, with automatic one-year term extensions on each anniversary of the effective date, until a party gives 90 days' notice of non-renewal. Mr. Gibson's agreement is now in effect until October 22, 2021. The Employment Agreement with Ms. Shamburger was entered into as of June 4, 2008, and had an initial term through June 4, 2010, with automatic one-year term extensions on each anniversary of the effective date, until a party gives 90 days' notice of non-renewal. The employment term was amended to a three-year term on October 25, 2018, with automatic one- year term extensions on each anniversary of the amendment date, until a party gives 90 days' notice of non-renewal. This agreement is now in effect until October 25, 2021. The Employment Agreement with Mr. McCabe was entered into as of November 17, 2008 and had an initial term through November 17, 2011, with automatic one-year term extensions on each anniversary of the effective date, until a party gives 90 days' notice of non-renewal. This agreement is now in effect until November 17, 2021.

The Employment Agreements provide for an annual base salary to be reviewed no less frequently than annually by the Committee, and entitle the executives to participate in the Company's Annual Incentive Programs with a payment of not less than 12.5% of base salary. The amount actually awarded and paid to the executives each year will be determined by the Committee and may be based on specific performance criteria.

The Employment Agreements entitle the executives to participate in all incentive, savings and retirement plans or programs and welfare and fringe benefits which are generally available to officers of the Company of comparable levels. In addition, the Employment Agreements state that the Company may pay country club annual dues and expenses for each of the executives.

The Employment Agreements also provide the executives with severance benefits in the event of certain terminations of employment. These benefits are described in “Potential Payments upon Termination or Change in Control.”

Key Employee Retention Agreement

The Key Employee Retention Agreement with H. J. Shands, III, provides for a grant of options and RSUs within 90 days following the Diboll acquisition, each having a grant date fair value equal to approximately 15% of Mr. Shands' base salary and vesting over four years, as well as three retention payments, beginning 90 days after the merger effective date and ending at the second anniversary date. Under the terms of the Key Employee Retention Agreement with H. J. Shands, III, if Mr. Shands' employment is terminated other than for Cause or Disability (as defined in the agreement), he is entitled to a portion of the remaining retention payments. As of December 31, 2018, the potential amount of payment for termination other than Cause or Disability was $48,000. The agreement does not provide for acceleration of the equity awards.

Split Dollar Agreements

In 2004, the Company entered into a split dollar agreement with Lee R. Gibson. The agreement provides that the Company will be the beneficiary of Bank Owned Life Insurance (commonly referred to as BOLI) insuring the executive’s life. The agreement provides Mr. Gibson with the right to designate the beneficiaries of the death benefits guaranteed in the agreement. The agreement originally provided for death benefits in an aggregate amount of $700,000. The amount is increased annually on the anniversary date of the agreement by an inflation adjustment factor of 5%. As of December 31, 2018, the expected death benefits totaled $1.4 million under this agreement. The agreement also states that after Mr. Gibson's retirement date, the Company will pay an annual gross-up bonus to him in an amount sufficient to enable him to pay federal income tax on both the economic benefit and on the gross-up bonus itself. There was no expense associated with the post retirement liability for the year ended December 31, 2018.

Pension Plan

The Pension Plan is a tax-qualified defined benefit pension plan pursuant to which participants are entitled to benefits based on final average monthly compensation and years of credited service.

Entrance into the Pension Plan by new employees was frozen effective December 31, 2005. Employees hired after December 31, 2005 are not eligible to participate in the Pension Plan. All participants in the Pension Plan are fully vested. All NEOs employed by the Company at December 31, 2018 were participants in the Pension Plan, with the exception of Mr. Shands. Benefits are payable monthly commencing on the later of age 65 or the participant’s date of retirement. Eligible participants may retire at reduced benefit levels after reaching age 55.

The benefits under the Pension Plan are determined using the following formula, stated as a single life annuity with 120 payments guaranteed, payable at normal retirement age, which is defined as 65 under the Pension Plan.

Benefit Formula Definitions

Credit Service

A participant’s years of credited service are based on the number of years an employee works for the Company. The Company has no policy to grant extra years of credited service.

Final Average Monthly Compensation (FAMC)

The monthly average of the 60 consecutive months’ compensation during the participant’s period of credited service that gives the highest average. Compensation generally includes all gross income received by the participant for services actually rendered in the course of employment, with certain exclusions, plus any elective deferrals under Section 125 and Section 404(g)(c). Compensation in the Pension Plan is limited as required.

Covered Compensation

A rounded 35-year average of the Maximum Taxable Wages (MTW) under social security. The table in effect during the calendar year proceeding termination or retirement is used.

The Pension Plan was amended several years ago and participants must now retire to be eligible to receive payments from the plan. All participants receiving payments from the Pension Plan at the time of the amendment were grandfathered so as to allow them to continue receiving payments from the plan. None of the NEOs were in pay status under the Pension Plan at the time of the amendment, and thus were not grandfathered.

The pension disclosures have been computed using the FASB ASC Topic 715, “Compensation - Retirement Benefits” assumptions from the financial statements as of the pension measurement date of December 31, 2018, except the FASB ASC Topic 715 retirement age has been replaced by the normal retirement age for this calculation (and the benefit valued is only the accrued, not the projected, benefit).

Restoration Plan

The annual retirement income benefit of NEOs under the Pension Plan is subject to certain limitations imposed by the Internal Revenue Code. Under one such limitation, in determining the benefit accrued for a year under the Pension Plan, the benefit formula excludes a NEOs compensation above a specified compensation limit. In 2018, for example, the ceiling was $275,000, which means that the compensation of NEOs in excess of that amount was not considered in the benefit formula for purposes of determining benefits under the Pension Plan. The Company maintains the Restoration Plan, a non-qualified supplemental retirement plan which provides additional benefits by taking into account the excess compensation not taken into account under the Pension Plan. The Restoration Plan is unfunded and noncontributory, which means that benefits are paid from the general assets of the Company and the NEOs are not required to make any contributions. The formula and assumptions used to calculate the benefit payable pursuant to the Restoration Plan are the same as those used under the Pension Plan described above, except that the amounts payable under the Restoration Plan are reduced by the amounts payable under the Pension Plan.

Deferred Compensation Agreements

Under the terms of their deferred compensation agreements, Lee R. Gibson is entitled to receive $400,000, and Julie N. Shamburger, Tim Alexander and Brian K. McCabe are each entitled to receive $300,000, all of which are payable monthly over 10 years, if the executive remains in the employment of Southside Bank until retirement (on or after age 65), or upon permanent disability or death, whichever occurs first. If the executive’s employment is involuntarily terminated by the Company for any reason other than for “good cause” (as defined in the agreements), such termination shall be treated the same as a retirement, and the executive shall be entitled to receive the payments. If, prior to a “change in control” (as defined in the agreements), the executive terminates his employment prior to attainment of age 65 for any reason other than death or disability, no amounts shall be due such executive under his deferred compensation agreement. If, after a change in control, the executive terminates employment prior to attainment of age 65 for any reason other than death, disability, or for “good reason” (as defined in the agreements), no amounts shall be due to the executive under his agreement. After a change in control, a termination by the executive for good reason shall be treated the same as a retirement, and the executive shall be entitled to receive the payments.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The following discussion summarizes the compensation benefits payable to the NEOs in the event of a termination of their employment under various circumstances, assuming that a termination of employment occurred on December 31, 2018.

Vested Benefits

Upon termination of their employment, the NEOs would receive compensation and benefits for which they had already vested. This would include accrued but unpaid salary, accrued and unused vacation pay, and any balance under the 401(k) plan. In addition, the NEOs would receive benefits under the Pension Plan and Restoration Plan, plus amounts payable under their deferred compensation agreements, as disclosed and described above in the 2018 Pension Benefits Table.

Employment Agreements

In addition, the Company has employment agreements with Lee R. Gibson, Julie N. Shamburger and Brian K. McCabe which entitle each of the executives to certain payments and benefits upon termination or change in control, as summarized below.

Voluntary termination by the executive; termination by the Company with Cause. If an executive voluntarily terminates his/her employment or the Company terminates the executive’s employment with Cause (as defined in the Employment Agreements), the executive will be entitled to receive his or her accrued salary and previously vested benefits. In this event, no special severance benefits are payable.

Involuntary termination. If the Company terminates the executive’s employment without Cause, the executive will be entitled to receive a single lump sum equal to:


•	any accrued but unpaid base salary;


•	a severance payment equal to the executive’s monthly salary multiplied by the number of months remaining in the term of the Employment Agreement (which would be between 24 and 36 months), plus $10,000;


•	a pro-rata bonus equal to the product of (i) the executive’s Target Bonus (as defined in the Employment Agreements) for the termination year and (ii) a fraction, the numerator of which is the number of days in the current fiscal year through the termination date, and the denominator of which is 365; and


•	any vested compensation deferred by the executive (unless otherwise required by an agreement).

Additionally, all equity awards will become immediately vested and exercisable as of the date of termination. Finally, the executive will be entitled to any other amounts or benefits under any other plan pursuant to which the executive is eligible to receive benefits, to the extent officers of a comparable level at the Company received such benefits prior to the date of termination (“Other Benefits”).

Termination due to death, Disability or Retirement. If an executive’s employment is terminated due to death, Disability or Retirement (as such capitalized terms are defined in the Employment Agreements), he or she (or his or her estate) will receive accrued salary and Other Benefits.

Termination in connection with Change in Control. If an executive’s employment is terminated due to a Change in Control (as defined in the Employment Agreements), he or she will be entitled to the same payments and benefits as if he or she had been terminated without cause. However, instead of the severance payment described above, the severance payment will be calculated as follows:

(a)

if the termination occurs more than six (6) months prior to a change of control or more than two (2) years after the occurrence of a change of control, the severance payment shall be the product of two times the sum of (1) the executive’s salary in effect as of the termination (ignoring any decrease in the salary unless consented to by the executive), and (2) the greater of the average of the annual bonuses earned by the executive for the two fiscal years in which annual bonuses were paid immediately preceding the year in which the termination occurs, or the executive’s Target Bonus for the year in which the termination occurs; or

(b)

if the termination occurs within six months prior or within two years after the occurrence of a change of control, the severance payment shall be the product of 2.99 for Lee R. Gibson and 2.0 for Julie N. Shamburger and Brian K. McCabe times the sum of (1) the executive’s salary in effect as of the termination, and (2) the greater of the average of the annual bonuses earned by the executive for the two fiscal years in which annual bonuses were paid immediately preceding the year in which the termination occurs, or the executive’s Target Bonus for the year in which the termination occurs.

Restrictive covenants. The Employment Agreements contain confidentiality provisions and subject Lee R. Gibson to certain non-compete and non-solicitation obligations during the term of employment with the Company for a one-year period and Julie N. Shamburger and Brian K. McCabe for a six-month period following termination of employment.

Reduction in certain benefits. The Employment Agreements also state that in the event that any of the severance benefits described above are subject to federal excise taxes under the “golden parachute” provisions under Section 280G of the Internal Revenue Code, the payments will be reduced to the extent necessary to avoid such excise taxes, but only if such reduction would result in a greater net benefit for the executive.

The following table quantifies the severance payments payable to Lee R. Gibson, Julie N. Shamburger and Brian K. McCabe pursuant to their Employment Agreements, and to H. J. Shands, III, pursuant to his Key Employee Retention Agreement, had their employment been involuntarily terminated as of December 31, 2018, either absent or in connection with a Change in Control, and the value of equity acceleration the NEOs would receive upon an involuntary termination following a Change in Control pursuant to the terms of the stock option and RSU award agreements. No amounts for pro rata bonuses are included in the table because the disclosure assumes a termination of employment as of the last day of the Company's fiscal year. Actual amounts earned as annual incentives for 2018 are disclosed in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.

NON-BINDING ADVISORY VOTE ON EXECUTIVE COMPENSATION

(PROPOSAL 2)

Pursuant to Section 14A of the Exchange Act, we are providing our shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers. At the 2018 Annual Meeting of Shareholders, approximately 96% of the shares represented at the meeting in person or by proxy and entitled to vote were voted in support of the Company’s compensation program. Also at the 2018 Annual Meeting, the Company’s shareholders selected, on a non-binding, advisory basis, an annual vote for the frequency at which the Company should include a Say-on-Pay vote in its proxy statement for shareholder consideration. In light of this result and other factors considered by the Board, the Board determined that the Company will hold Say-on-Pay votes every year until the next required non-binding, advisory vote on the frequency of such votes, which is required to be held no later than the Company’s 2023 Annual Meeting of Shareholders.

Accordingly, the Board is providing shareholders with the opportunity to cast a non-binding advisory vote on the named executive officer compensation program at our 2019 Annual Meeting. This vote will not be binding on or overrule any decisions by the Board, and will not create or imply any additional fiduciary duty on the part of the Board. However, our Compensation Committee will take into account the outcome of the vote when considering future named executive officer compensation arrangements.

As described in greater detail in our Compensation Discussion and Analysis above, we believe that our executive officer compensation program is structured in a manner that most effectively supports the Company and our business objectives. Our executive officer compensation program is designed to reward long-term and strategic performance, and is substantially tied to our key business objectives and the success of our shareholders. We monitor the various short-term and long-term aspects of our executive officer compensation program, including base salary, annual cash bonus and equity incentives, in comparison to similar programs and practices at comparable companies, so that we may ensure that our executive officer compensation program is within the competitive range of market practices.

The Board invites our shareholders to review carefully the Compensation Discussion and Analysis and the tabular and other disclosures on compensation under Executive Compensation, and cast a vote to approve the Company’s executive compensation programs through the following resolution:

“RESOLVED, that the shareholders approve the compensation paid to the Company’s named executive officers, as disclosed in this proxy statement pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the compensation tables and related narrative discussion.”

The Board recommends a vote FOR the non-binding advisory vote on executive compensation.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

None of the members of the Compensation Committee, during the fiscal year ended December 31, 2018, are a current or former officer or employee of the Company.

During the fiscal year ended December 31, 2018:


•	No executive officer of the Company served as a member of the compensation committee or other board committee performing similar functions (or on the board of directors of any entity without such a committee) of another entity, one of whose executive officers served on the Compensation Committee of the Company.


•	No executive officer of the Company served on the board of directors of another entity, one of whose executive officers served on the Compensation Committee of the Company.


•	No executive officer of the Company served as a member of the compensation committee or other board committee performing similar functions (or on the board of directors of any entity without such a committee) of another entity, one of whose executive officers served as a director of the Company.

For information concerning transactions by the Company and Southside Bank with certain members of the board of directors of Southside Bank, please see “Transactions with Directors, Officers and Associates.”

TRANSACTIONS WITH DIRECTORS, OFFICERS AND ASSOCIATES

The Board of Directors reviews and discusses each potential transaction with a director, executive officer, significant shareholder or any of their immediate family members and votes to approve or disapprove such transactions. Directors or executive officers who are interested in a particular transaction do not vote on the transaction with respect to which they are interested. The Company’s Board has adopted a Conflict of Interest Policy that addresses transactions with related persons.

Certain of the executive officers and directors of the Company and Southside Bank (and their associates) have been customers of Southside Bank and have been granted loans in the ordinary course of business. Southside Bank is subject to Federal Reserve Regulation O, which governs loans to directors, executive officers and certain shareholders of banks and bank holding companies. All loans or other extensions of credit made by Southside Bank to executive officers and directors of the Company and Southside Bank were made in the ordinary course of business on substantially the same terms, including interest rates, maturities and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company or Southside Bank and did not involve more than the normal risk of collection or present other features that are unfavorable to Southside Bank. Prior approval by a majority of the board of directors, with the interested party abstaining, must be obtained for any loan to a director or a director’s related interest(s) which, when aggregated with all loans to the director and/or to that director’s related interest(s) exceed 10% of Southside Bank’s capital plus unimpaired surplus. Prior approval requirements for individual advances for the Board of Directors will be satisfied by annual Board approval of a line of credit for a director’s personal borrowing and similar approval of a line of credit for director-owned or controlled business borrowing. All advances made pursuant to an approved line of credit within 12 months of the date of approval shall be treated as approved. Loans to persons employed by Southside Bank who are considered under Regulations of the Federal Reserve Board to be executive officers shall be subject to prior approval by the board of directors. The Company expects ongoing transactions with its executive officers and directors as well as directors and officers of Southside Bank. Richard K. Gibson, son of Lee R. Gibson, is employed by Southside Bank and received compensation of $247,487 in 2018. Joe C. (Trey) Denman, III, brother-in-law of M. Richard Warner, is employed by Southside Bank and received compensation in 2018 of $737,487, which includes retention payments of $160,000 and grants of stock options and RSUs with a grant date fair value of approximately $99,366, pursuant to Mr. Denman's Key Employee Retention

Agreement. In addition, George H. (Trey) Henderson, III, a member of the Company’s Board, owns a 20% interest in HFive Partners, Ltd., together and equally with his four siblings, and exercises managerial authority over the partnership. HFive Partners, Ltd. owns 9.9% of Coss Partners, Ltd. Mr. Henderson has provided a limited personal guaranty of approximately 4.0% of the principal balance of the loan. Such loan was made by First Bank & Trust East Texas, which the Company acquired on November 30, 2017, in the ordinary course of business and on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to First Bank & Trust East Texas. At the time this loan was made, the loan did not involve more than the normal risk of collectability.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires the Company’s executive officers and directors, and any persons who own more than 10% of the Company’s common stock, to file reports of initial ownership of the Company’s common stock and subsequent changes in that ownership with the SEC. Executive officers, directors and greater than 10% shareholders are required by SEC regulations to furnish the Company with copies of all forms they file pursuant to Section 16(a). Based solely upon a review of the copies of the forms furnished to the Company, or written representations from certain reporting persons that no Form 5’s were required, the Company believes that during fiscal year 2018 all Section 16(a) filing requirements were complied with on a timely basis except that:


•	Officer Earl W. (Bill) Clawater, III, filed a late Form 4 on November 30, 2018 to report the disposition of 61 shares due to tax withholding related to the vesting of RSUs on November 23, 2018.

•

Officer and CFO, Julie N. Shamburger, filed an amended Form 4 on December 21, 2018 to correct a filing on December 10, 2018, which inadvertently omitted two transactions that occurred on December 6, 2018. One transaction was a disposition of two shares for tax withholdings on dividend equivalents on shares associated with a cash dividend, and the other transaction was an acquisition of 31 shares due to dividend equivalents on RSUs.

AUDIT COMMITTEE REPORT

The following report of the Audit Committee does not constitute “soliciting material” and should not be deemed to be “filed” with the SEC or incorporated by reference into any other filing of the Company under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates this report by reference in any of those filings.

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. The Company’s management has the primary responsibility for the financial statements and for maintaining effective systems of internal control based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements contained in the Annual Report on Form 10-K for the year ended December 31, 2018 with Company management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee discussed with the independent registered certified public accounting firm, EY, which is responsible for expressing an opinion on the conformity of those audited consolidated financial statements with U.S. generally accepted accounting principles and an audit on the effectiveness of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (the “PCAOB”) (United States), its judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee by Auditing Standard No. 16, as adopted by the PCAOB, other standards of the PCAOB, rules of the SEC, and other applicable regulations.

The Audit Committee has received the written disclosures from EY regarding the auditors' independence required by PCAOB Ethics and Independence Rule 3526, “Communication with Audit Committees Concerning Independence.”

The Audit Committee discussed with EY the overall scope and plans for their audit. The Audit Committee met with EY with and without management present, to discuss the results of their financial statement audit, their evaluations of the Company’s internal control and the overall quality of the Company’s financial reporting.

Based on the Audit Committee’s review and discussions referred to above, the Audit Committee recommended to the Company’s Board of Directors that the Company’s audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 for filing with the SEC.

Submitted by the Audit Committee of the Board.

Auditor Fees Pre-Approval Policy

The Audit Committee has a formal policy concerning approval of audit and non-audit services to be provided by the independent registered public accounting firm to the Company, currently EY. The Policy requires that all services EY may provide to the Company, including audit services and permitted audit-related and non-audit services, be pre-approved by the Audit Committee. The Audit Committee pre-approved all audit, audit-related and non-audit services provided by EY during 2018.

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

(PROPOSAL 3)

The Audit Committee of the Board has selected EY to serve as the Company’s independent registered public accounting firm for the year ending December 31, 2019. EY has served as the Company’s independent registered public accounting firm since 2012. We have been advised by EY that neither it nor any of its members had any financial interest, direct or indirect, in us nor has it had any connection with us or any of our subsidiaries in any capacity other than as independent auditors. The Board recommends that you vote for the ratification of the selection of EY. Shareholder ratification of the selection of EY as our independent registered public accounting firm is not required by our certificate of formation, bylaws or otherwise. Nevertheless, the Board is submitting this matter to the shareholders as what we believe is a matter of good corporate practice. If the shareholders do not ratify the appointment of EY, then the appointment of an independent registered public accounting firm will be reconsidered by our Audit Committee. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it is determined that such a change would be in the best interest of the Company and its shareholders. Representatives of EY are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so, and to respond to appropriate questions.

The Board of Directors recommends a vote FOR the ratification of Ernst & Young LLP as the Company’s independent registered public accounting firm for the year 2019.

ANNUAL REPORT TO SHAREHOLDERS

The Company’s Annual Report on Form 10-K, as integrated into the Annual Report to Shareholders for the fiscal year ended December 31, 2018, accompanies this Proxy Statement. The Annual Report does not constitute outside solicitation materials. Additional copies of Form 10-K are available at no expense; exhibits to Form 10-K are available for a copying expense to any shareholder by sending a written request to the Corporate Secretary of the Company, Post Office Box 8444, Tyler, Texas 75711. The Company’s public filings with the SEC may also be obtained free at the Company’s website: http://investors.southside.com, under the topic Filings and Financials then Documents.

SHAREHOLDER PROPOSALS

SEC rules establish the eligibility requirements and the procedures that must be followed for a shareholder’s proposal to be included in the Board’s proxy solicitation materials. Under those rules, any shareholder wishing to have a proposal considered for inclusion in the Board’s proxy solicitation materials for the 2020 Annual Meeting must set forth his or her proposal in writing and file it with the Secretary of the Company on or before December 4, 2019. Proposals must comply with all applicable SEC rules. The Board will review any proposals received by that date and will determine whether applicable requirements have been met for including the proposal in the 2020 proxy solicitation materials.

In addition, the Company’s bylaws establish advance notice procedures that must be followed for a shareholder proposal to be presented at an Annual Meeting but not included in the Board’s proxy solicitation materials. Any shareholder wishing to have a proposal considered for the 2020 Annual Meeting, but who does not submit the proposal for inclusion in the Board’s proxy statement, assuming that the 2020 Annual Meeting

occurs on a date that is not more than 30 days before or 60 days after the anniversary of the Annual Meeting, must submit the proposal as set forth above not earlier than January 16, 2020 and no later than February 15, 2020.

For any proposal that is not submitted for inclusion in next year’s proxy solicitation materials, but is submitted for presentation at the 2020 Annual Meeting, SEC rules permit the persons named as proxies in the proxy solicitation materials to vote proxies in their discretion if: (1) the proposal is received before February 15, 2020 and we advise shareholders in the 2020 proxy solicitation materials about the nature of the matter and how management intends to vote on such matter, or (2) the proposal is not received before February 15, 2020.

HOUSEHOLDING

The Securities and Exchange Commission rules permit us, with your permission, to send a single set of proxy statements and annual reports to any household at which two or more shareholders reside if we believe that they are members of the same family. Each shareholder will continue to receive a separate proxy card. This procedure, known as “householding,” reduces the volume of the duplicate information you receive and helps to reduce our expenses. In order to take advantage of this opportunity, we have delivered only one proxy statement to multiple shareholders who share an address, unless we received contrary instructions from the impacted shareholders prior to the mailing date. We will deliver a separate copy of the proxy statement, as requested, to any shareholder at a shared address to which a single copy of that document was delivered. If you prefer to receive separate copies of a proxy statement, either now or in the future, you can request a separate copy of the proxy statement by calling us at (877) 639-3511 or by writing to us at any time at the following address: Southside Bancshares, Inc., 1201 South Beckham Avenue, Tyler, Texas 75701, Attn: Investor Relations.

GENERAL

The Board does not know of any other business, other than that set forth above, to be transacted at the Annual Meeting. However, if any other matters requiring a vote of the shareholders properly come before the Annual Meeting, the persons designated as Proxies will vote the shares of common stock represented by the proxies in accordance with their best judgment on such matters. If a shareholder specifies a different choice on the proxy, those shares of common stock will be voted in accordance with the specification so made.
