To our shareholders:

In 2016, S&T Bancorp saw impressive returns on the investments in people and markets that we’ve made over the past few years. Those investments, in turn, have led to solid returns for you, our shareholders. It all contributed to record net income of $71.4 million.

With organic loan growth of 11.6 percent, we believe that our performance in 2016 is evidence of a sound business strategy that will continue to lead us on the path of continued and sustainable profitability.

2016 Financials

Financial highlights from 2016 include:


•	Net income increased to a record $71.4 million, or $2.05 per diluted share, compared to $67.1 million, or $1.98 per diluted share for 2015.


•	Return on average assets stood at 1.08 percent; return on average equity, 8.67 percent; and return on tangible equity, 13.71 percent.


•	Net interest income increased $15.7 million, or 8.4 percent, to $203.3 million compared to $187.6 million in 2015, driven primarily by loan growth of $584 million, or 11.6 percent.


•	Operating efficiently remains a key component of our success. During 2016, we had positive operating leverage with total revenue growth of $19.3 million, or 8.1 percent, while operating expenses increased $6.5 million, or 4.8 percent, compared to 2015.


•	Lastly, the Board of Directors declared cash dividends of $0.77 per share during 2016, a 5.5 percent increase from the 2015 declared cash dividends per share of $0.73.

2016 Highlights

S&T operates across five geographic markets, which together provide a great platform for steady organic growth. Although these markets have varying needs and preferences regarding specific banking and financial services, we are able to meet our customers’ demands by offering a wide variety of high-quality products typically found at our largest competitors. These offerings, when combined with superior level of customer service, were the keys to generating positive results in 2016. Here is a summary of performance across our five markets:

Southwestern Pennsylvania: The year was marked by the opening of a new corporate banking office on the North Shore of Pittsburgh, a core market for us, providing existing and new customers with direct access to business and commercial loans, and indirect access to treasury management and private banking services. Focused on C&I growth, the North Shore location offers the Pittsburgh region strategic banking solutions through a range of financial resources, including the extensive knowledge and insight into the area that our team represents.

Southcentral Pennsylvania: 2016 marked the first full year of Integrity Bancshares as part of S&T, with the integration progressing very well. Integrity expands our presence in southcentral Pennsylvania with eight



	1

branches in Cumberland, Dauphin, Lancaster, and York Counties. We have seen strong performance overall from these markets, thanks to the dedicated team of bankers whose similar approach to customer service dovetailed easily and immediately with the long-held culture of S&T.

Northeast Ohio: The S&T presence expanded in 2016 with the opening of a new branch in the fourth quarter, offering the full range of services to customers. We also brought on a new C&I lender to serve this important market. We made a significant investment in Akron, Ohio, relocating and expanding into a new banking facility to offer commercial, business, consumer, private banking, and treasury management services. This newly configured Akron location, which opened in December, will help S&T expand its growing presence in northeast Ohio by attracting new customers and deepening our relationships with existing customers.

Total loans: $344 million; Organic loan growth in 2016: $101 million.

Central Ohio: S&T’s presence in the greater Columbus market continued to expand in 2016, with notable loan growth. The stability of our growing staff in Central Ohio plays an important role in attracting and retaining relationships.

Total loans: $309 million; Organic loan growth in 2016: $113 million.

Western New York: Our loan production office (LPO) in Rochester, New York, generated impressive loan growth in 2016, as S&T continues to make significant inroads in this geographic region.

Total loans: $173 million; Organic loan growth in 2016: $140 million.

In addition, our major lines of business had solid performance, as well.

Commercial banking, comprising our corporate and business banking segments, remains a source of important loan growth and a key entry point to expanded relationships with valued customers. Loan production in this line of business totaled $1.4 billion in 2016.

In our Retail segment, we saw another strong year of performance, including a focus on generating deposits, which led to overall deposit growth of $396 million for the year. The retail base in our legacy markets, along with consumer and mortgage lending, consistently generates solid returns that help to fund growth initiatives bank wide. In addition, our retail locations maintain average deposits of $82.4 million per branch, a figure well above those in our peer group.

A comprehensive customer digital strategy also contributed to our retail success, with mobile first solutions delivering products and services to all demographic groups, especially millennials. Our digital strategy rests on the idea that S&T will deliver the same capabilities through on-line and mobile channels as we do in person. Our Solution Center (formerly called the Direct Banking Center) supports both digital and person-to-person experiences, bridging the gap for customers.

Our Wealth Management had $1.9 billion in assets under administration that produced annual revenue of $10.5 million. This revenue was generated through brokerage and trust services as well as through registered investment advisor services for institutional accounts. Our Insurance group had a solid year of new business generation in 2016, with $4.7 million in annual revenue.

Among other efforts, we are proud to have successfully completed three mergers since 2012, improved our delivery of services through LPOs and Innovation Banking Centers, upgraded internal systems, and improved cybersecurity while maintaining significant cost controls. We are proud to have accomplished all of our goals while still servicing our customers through a friendly bank. I am personally very proud of the way in which our S&T team - those who have been with us for years, and those who may be newer to the organization - have kept our culture intact and, to my way of thinking, actually made it stronger and offer them all a hearty ”Well done.”



	2

Our employees’ efforts in the service of the communities where we are located are clear evidence of our intent to maintain and grow our status as an exemplary community banking institution. For example, S&T employees’ donated more than $100,000 to the United Way in 2016, surpassing all previous years’ campaigns, and helped to eliminate hunger by devoting more than 1,200 volunteer hours to 21 local food banks. Other employees provided significant services to non-profit boards and organizations serving children, the elderly and others in need.

S&T’s belief in serving as a valuable community partner also included donating seedlings planted as part of the “Plant a Tree at Flight 93” effort at the National Park Service’s Flight 93 Memorial in nearby Somerset County, continuing to promote programs for students on financial literacy, and providing nearly $1 million in support to a variety of charitable organizations, including a donation of $10,000 to area food banks.

S&T continues to benefit from the wisdom, guidance, and diligence of our Board of Directors. As CEO, my appreciation for the professionalism and dedication of this group has only expanded and deepened over the years. They have my thanks and my pledge to keep our Bank strong and successful.

Special acknowledgement goes to two Directors retiring from the Board this year, Jack Delaney and William Gatti, who have provided outstanding service by representing our shareholders with diligence and wisdom for 30 and 24 years, respectively. I speak for everyone in our organization when I wish these two gentlemen all the best, with our deepest appreciation.

We believe our results for 2016 prove that this organization is moving in the right direction by following a proven strategy. We have the vision, products, services, geographic presence, and most of all the culture and the people, to remain on a path to continued profitable growth, and we anticipate this trend to extend into 2017.

We thank all of our shareholders for their past and continuing support.

Sincerely,

Todd D. Brice

President and Chief Executive Officer

PROXY STATEMENT FOR

ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD MAY 15, 2017

INTRODUCTION

This Proxy Statement is being furnished to shareholders of S&T Bancorp, Inc. (“S&T”) in connection with the solicitation of proxies by the Board of Directors of S&T (the “S&T Board”) for use at the Annual Meeting of Shareholders, and any adjournments thereof, to be held at the time and place set forth in the accompanying notice (“Annual Meeting”). We are first sending the Notice of Internet Availability of Proxy Materials (the “Notice”), or this Proxy Statement, S&T’s 2016 Annual Report and proxy card to shareholders on or about April 5, 2017.

At the Annual Meeting, shareholders of S&T will be asked to elect 13 directors of S&T to serve a one-year term, to approve the ratification of the selection of KPMG LLP as S&T's independent registered public accounting firm for the fiscal year 2017 and to approve a non-binding advisory proposal on the compensation of S&T’s named executive officers.

All shareholders are urged to read this Proxy Statement carefully and in its entirety.

MEETING INFORMATION

Date, Time and Place

The Annual Meeting will be held on May 15, 2017, at 10:00 a.m. Eastern Time at the S&T Support Center, located at Indiana West Plaza, 2416 Philadelphia Street, Indiana, Pennsylvania 15701.

Record Date, Voting Rights and Required Vote

The securities that can be voted at the Annual Meeting consist of shares of common stock of S&T, par value $2.50 per share (“Common Stock”), with each share entitling its owner to one vote on each matter to be voted on at the Annual Meeting. There are no cumulative voting rights with respect to the Common Stock. Only holders of the Common Stock at the close of business on March 17, 2017 (the “Record Date”) will be entitled to notice of and to vote at the Annual Meeting. There were 2,993 record holders of the Common Stock and 34,913,023 shares of Common Stock outstanding as of the Record Date.

A quorum is required for the transaction of business at the Annual Meeting. A “quorum” is the presence at the meeting, in person or represented by proxy, of the holders of the majority of the outstanding shares of Common Stock. Abstentions are counted for purposes of determining the presence or the absence of a quorum, but are not considered a vote cast under Pennsylvania law. Abstentions will not affect the outcome of a vote on a particular matter. Shares held by brokers in street name and for which the beneficial owners do not vote on a particular proposal because the brokers do not have discretionary voting power and have not received instructions from the beneficial owners to vote on that item are called “broker non-votes.” Brokers and banks have discretionary authority to vote shares in the absence of instructions on matters considered “routine,” such as the ratification of the appointment of the independent registered public accounting firm. They do not have discretionary authority to vote shares in the absence of instructions on “non-routine” matters, such as the election of directors and the advisory vote on the approval of compensation of S&T's named executive officers. Broker non-votes are counted to determine if a quorum is present, but are not considered a vote cast under Pennsylvania law. Broker non-votes will not affect the outcome of a vote on a particular matter.

The director nominees will be elected by a plurality of the votes cast at the Annual Meeting, which means that the 13 nominees receiving the most votes will be elected. A withheld vote on any nominee will not affect the voting results. The ratification of the selection of KPMG LLP as S&T's independent registered public accounting firm for fiscal year 2017 and the approval of the non-binding advisory proposal on the compensation of S&T’s named executive officers require the affirmative vote of a majority of the votes cast at the Annual Meeting to be approved.

Voting and Revocation of Proxies

Shareholder of Record. If you are a shareholder of record and you received the Notice, you may vote by accessing the secure Internet website registration page identified on the Notice and following the instructions, or by mail or telephone if you request a printed copy of the proxy materials by following the instructions set forth on the Notice. You may also vote in person at the Annual Meeting.

If you are a shareholder of record and you received a printed copy of this Proxy Statement, S&T’s 2016 Annual Report and the proxy card, you may submit your proxy card and voting instructions by telephone or using the Internet or by mail as further described below. Your proxy card, whether submitted via telephone, the Internet or mail, authorizes the individuals named as proxies on your proxy card to act as your proxies at the Annual Meeting, each with the power to appoint his or her substitute, to represent and vote your shares of S&T Common Stock as you directed, if applicable.


•	By Telephone. Call the toll-free telephone number on the enclosed proxy card (1-800-690-6903) and follow the recorded instructions.


•	By Internet. Access the secure Internet website registration page on the enclosed proxy card and follow the instructions.


•	By Mail. Sign, date and return your proxy card in the postage-paid envelope provided.

If you submit your proxy card and voting instructions via telephone or the Internet, you do not need to mail your proxy card. The individuals named as proxies on your proxy card will vote your shares of S&T Common Stock at the Annual Meeting as instructed by the latest dated proxy received from you, whether submitted via the Internet, telephone or mail. You may also vote in person at the Annual Meeting.

Beneficial Owners. If your shares of S&T Common Stock are held in a stock brokerage account by a bank, broker, trustee or other nominee, you are considered the beneficial owner of shares held in street name and these proxy materials are being forwarded to you by your bank, broker, trustee or other nominee that is considered the shareholder of record of those shares. As the beneficial owner, you have the right to direct your bank, broker, trustee or other nominee on how to vote your shares of S&T Common Stock via the Internet or by telephone, if the bank, broker, trustee or other nominee offers these options or by completing, signing, dating and returning a voting instruction form. Your bank, broker, trustee or other nominee will send you instructions on how to submit your voting instructions for your shares of S&T Common Stock. If you wish to vote in person at the Annual Meeting, you must obtain a signed proxy from your bank, broker, trustee or other nominee who holds the shares on your behalf in order to cast your vote.

If you properly complete, sign, date and return the proxy card or voting instruction form, your shares of S&T Common Stock will be voted as you specify. If you are a shareholder of record and you sign and return the proxy card, but make no specifications on such proxy card, your shares of S&T Common Stock will be voted in accordance with the recommendations of the S&T Board. If you are a beneficial owner and you do not provide voting instructions to your bank, broker, trustee or other nominee holding shares of S&T Common Stock for you, your shares of S&T Common Stock will not be voted with respect to any proposal for which the shareholder of record does not have discretionary authority to vote.

Except for procedural matters incident to the conduct of the Annual Meeting, S&T does not know of any matters other than those described in the Notice of Annual Meeting of Shareholders that are to come before the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the persons named in the accompanying proxy will vote the shares represented by the proxies in their discretion on such matters as recommended by a majority of the S&T Board.

The presence of a shareholder at the Annual Meeting will not automatically revoke such shareholder’s proxy. However, a shareholder may revoke a proxy at any time prior to its exercise by filing with the Secretary of S&T a written notice of revocation, by delivering to S&T a duly executed proxy bearing a later date or by attending the Annual Meeting and voting in person.

Solicitation of Proxies

The cost of soliciting proxies will be borne by S&T. In addition to the solicitation of proxies by mail, S&T has engaged D.F. King & Co., Inc. to help solicit proxies for the Annual Meeting, and will pay D.F. King & Co., Inc. $8,000, plus its out-of-pocket expenses, for the solicitation of proxies. S&T may also solicit proxies personally or by telephone, through its directors, officers and regular employees. S&T also will request persons, firms and corporations holding shares of Common Stock in their names or in the name of their nominees, which are beneficially owned by others, to send proxy materials to and obtain proxies from the beneficial owners and will reimburse the holders for their reasonable expenses in so doing.

Internet Availability of Proxy Materials

S&T’s Proxy Statement for the Annual Meeting and S&T’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, are available at http://proxyvote.com.

Householding

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices or proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single Notice or proxy statement and annual report addressed to those shareholders. This process is commonly referred to as “householding.”

S&T has implemented “householding” in an effort to reduce the number of duplicate mailings to the same address. This process benefits both shareholders and S&T, because it eliminates unnecessary mailings delivered to your home and helps to reduce S&T’s expenses. “Householding” is not being used, however, if S&T has received contrary instructions from one or more of the shareholders sharing an address. If your household has received only one Notice or one annual report and proxy statement package, S&T will deliver promptly a separate copy of the Notice or annual report and the proxy statement package to any shareholder who contacts S&T by calling the toll-free number, 1-800-325-2265, or by mail to the attention of the Secretary of S&T at 800 Philadelphia Street, Indiana, Pennsylvania 15701. You can also notify S&T that you would like to receive separate copies of S&T’s annual report and proxy statement in the future by calling S&T. If your household has received multiple copies of S&T’s annual report and proxy statement, you can request the delivery of single copies in the future by calling S&T, as instructed above, or your broker, if you hold the shares in “street name.”

If you received more than one Notice or proxy card, it means that your shares are registered in more than one name (e.g., trust, custodial accounts, joint tenancy) or in multiple accounts. Please make sure that you vote all of your shares by following the directions on each Notice or on each proxy card you received.

For our 2018 annual meeting, you can help us save significant printing and mailing expenses by consenting to access our proxy materials electronically via the Internet. If you hold your shares in your own name (instead of “street name” through a bank, broker or other nominee), you can choose this option by following the prompts for consenting to electronic access, if voting by telephone, or by following the instructions at the Internet voting website at www.proxyvote.com, which has been established for you to vote your shares for the 2017 Annual Meeting. If you choose to receive your proxy materials electronically, then prior to next year’s annual meeting you will receive notification when the proxy materials are available for on-line review via the Internet, as well as the instructions for voting electronically via the Internet. Your choice for electronic distribution will remain in effect until you revoke it by sending a written request to S&T to the attention of the Secretary of S&T at 800 Philadelphia Street, Indiana, Pennsylvania 15701. If you hold your shares in “street name” through a bank, broker or other nominee, you should follow the instructions provided by that entity if you wish to access our proxy materials electronically via the Internet.

BENEFICIAL OWNERS OF S&T COMMON STOCK

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires S&T’s directors and executive officers, and persons who own more than 10% of S&T’s stock, to report to the SEC certain of their transactions with respect to S&T’s Common Stock. The SEC reporting rules require that changes in beneficial ownership generally be reported on Form 4 within two business days after the date on which the change occurs. A Form 3 to report stock holdings in S&T must be filed within ten days of when a director, executive officer or person who owns more than 10% of S&T’s stock becomes subject to Section 16(a) of the Exchange Act.

Officers, directors and greater than 10% shareholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file. To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended December 31, 2016, all Section 16(a) filing requirements applicable to our executive officers, directors and greater than 10% beneficial owners were filed in a timely manner, except for the following reports filed late: one Form 4 filed by Mr. Thomas Sposito, reporting one transaction of shares acquired on January 28, 2016; two Form 4s filed by Mr. Jerry Hostetter, each reporting one transaction of shares sold on November 14, 2016; and two Form 4s filed by Mr. James Gibson, each reporting two transactions of shares sold, such sales being made on November 19, 2016, November 21, 2016 and November 22, 2016. In addition, Mr. William Poole filed a Form 5 in 2016 reporting one transaction of shares purchased in the 401(k) plan on November 17, 2015, on an untimely basis. The transaction occurred while Mr. Poole was an executive officer of S&T. The late filings were inadvertent.

PROPOSAL 1—ELECTION OF DIRECTORS

General

The By-laws of S&T provide that the number of directors constituting the S&T Board will consist of not less than nine (9) nor more than seventeen (17), with the exact number to be fixed and determined from time to time by resolution of a majority of the S&T Board. Currently, the S&T Board has fixed the number of directors at fourteen (14); however, the number of directors will be reduced by the S&T Board to thirteen (13) effective as of the date of the Annual Meeting, when Directors Delaney and Gatti retire. The S&T Board has nominated the thirteen (13) persons named below for election at the Annual Meeting, including twelve (12) incumbent directors up for re-election and Mr. Robert E. Kane, our new director nominee.

The nominees were each recommended by our Nominating and Corporate Governance Committee (the “Nominating Committee”) to the S&T Board. Each director nominee will serve a one-year term. All of the nominees have indicated their willingness to serve, if elected, but if any should be unable to serve or unwilling to serve for good cause, proxies may be voted for a substitute nominee designated by the S&T Board. There are no family relationships between or among any of our directors, executive officers or persons nominated or chosen to become a director or executive officer, except that Director Delaney’s son is married to Director and CEO Brice’s sister. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the nominees named below.

Set forth below is a brief description of the principal occupation and business experience of each of our nominees for director, as well as the summary of our views as to the qualifications of each nominee and continuing director to serve on the S&T Board. Our views are informed not only by the current and prior employment and educational background of our directors, but also by the S&T Board’s experience in working with their fellow directors. The S&T Board has had significant experience with the incumbent directors and has had the opportunity to assess the contributions that the directors have made to the S&T Board as well as their industry knowledge, judgment and leadership capabilities. The Nominating Committee continually assesses the tenure and diversity of the S&T Board and seeks opportunities, within the constraint of the size of the S&T Board, to include a mix of directors with S&T Board experience and with fresh perspectives. In the last five years, the Nominating Committee has had the opportunity to add five or nearly 40% new directors to the S&T Board to further diversify the S&T Board’s industry knowledge, judgment and leadership capabilities. Mr. Palermo was added to the S&T Board in 2013; Messrs. Gibson, Hostetter and Weingarten were added to the S&T Board through the acquisition of Integrity Bancshares, Inc. ("Integrity") in 2015 and Mr. Kane is being nominated to the S&T Board in 2017. Mr. Kane was recommended for consideration as a director nominee by a member of the Nominating Committee.

Director Nominees to be Elected at the 2017 Annual Meeting:

Todd D. Brice, 54, has served as a director of S&T since 2005. Mr. Brice has been President and Chief Executive Officer of S&T and S&T Bank since 2008 and was formerly President and Chief Operating Officer of S&T and S&T Bank from 2004 until 2008 and Executive Vice President of Commercial Lending at S&T and S&T Bank from 2002 until 2004. With 31 years of banking experience, including 15 years of senior management experience at S&T, we believe that Mr. Brice’s deep industry knowledge and his expertise in our operations, commercial lending and corporate strategy provides the S&T Board with significant insight across a broad range of issues critical to our business. As our Chief Executive Officer, Mr. Brice provides unique insight to the S&T Board regarding our day-to-day operations, customer information, competitive intelligence, general trends in national and local banking and issues regarding our financial results.

Michael J. Donnelly, 59, has served as a director of S&T since 2001 and is a member of the Compensation and Benefits Committee (the "Compensation Committee") and the Nominating Committee. Mr. Donnelly has been president of Indiana Printing and Publishing Company, Inc. since 1993. We believe that Mr. Donnelly’s deep experience in managing and operating a local business provides the S&T Board with valuable insight into the issues addressing our local corporate and consumer borrowers. Mr. Donnelly has spent over 27 years working with the Indiana County Chamber of Commerce and the Indiana County Development Corporation in retaining and attracting many businesses in the Indiana, PA area. Mr. Donnelly’s experience in developing appropriate compensation for the executives and senior management of his company qualifies him to serve on our Compensation Committee, and his experience on the S&T Board provides him with a solid background for service on our Nominating Committee.

James T. Gibson, 61, has served as a director of S&T since March 2015. Mr. Gibson served as chairman, president and chief executive officer of Integrity since its inception in June 2003 until it was acquired by S&T in March 2015, and served as president and chief executive officer of Integrity Bank, a role he also held since its inception in June 2003 until it was merged into S&T Bank in May 2015. Mr. Gibson assisted the S&T Board with transition and integration issues following the acquisition

of Integrity in 2015, and retired December 31, 2015. Previously, Mr. Gibson served as president and chief executive officer of Commerce Bank/Harrisburg from 1988 to 2002. We believe that Mr. Gibson’s more than 37 years of banking experience and detailed knowledge about the development and operations of Integrity Bank qualify him to serve on our Board.

Jeffrey D. Grube, 63, has served as a director of S&T since 1997 and is Chairman of the Compensation Committee and a member of the Audit Committee. Mr. Grube has served as president of B.F.G. Electroplating and Manufacturing Company as well as B.F.G. Manufacturing Service, Inc. since 1990. Mr. Grube’s career as an executive in the manufacturing industry includes financial and engineering experience. Mr. Grube’s extensive experience working with small and medium-sized businesses provides the S&T Board with valuable experience regarding potential borrowers and customers, customer relations, lending issues and credit risk. Mr. Grube also served as a director on the board of a privately held company that supplies compliance products for lending solutions. Mr. Grube’s executive and board experience in the manufacturing sector and experience with financial institutions allow him to bring relevant insight regarding regulatory and financial compliance issues to the S&T Board, including the Audit Committee and the Compensation Committee.

Jerry D. Hostetter, 55, has served as a director of S&T since March 2015 and is a member of the Compensation Committee. Mr. Hostetter has served as a partner at Prestige Investment Group since its founding in 2012. Prior to that, Mr. Hostetter was the vice president of fund development and legislative affairs of Ephrata Community Hospital from 2008 through 2011. Mr. Hostetter previously served on the board of Integrity from 2011 until it was acquired by S&T in March 2015. We believe that Mr. Hostetter’s experience in the Pennsylvania business community and knowledge gained from his service as a director of Integrity qualify him to serve on the S&T Board and on the Compensation Committee.

Frank W. Jones, 71, has served as a director of S&T since 1997 and is Chairman of the Nominating Committee and a member of the Audit Committee. In January 2015, Mr. Jones became of counsel with the law firm of Creenan & Baczkowski, PC in Murrysville, PA. Prior to joining the law firm, Mr. Jones was practicing law independently in Allegheny County from 1970 to December 2014. Mr. Jones joined the S&T Board following the acquisition of People’s Bank of Unity, a regional financial institution, where he served on the board of directors. Mr. Jones assisted the S&T Board with integration and strategic issues following the acquisition. Mr. Jones’ legal practice, which focuses on estate administration and estate litigation, allows him to provide valuable insight to the S&T Board specifically with respect to our Wealth Management division, including on such issues as customer acquisition, marketing, strategic considerations, compliance and legal risk. We believe that Mr. Jones’ experience as a director of a similar bank to S&T Bank, together with his legal experience as it relates to one of our core businesses and his years of experience on the S&T Board, qualifies him to serve as a director and serve on our Audit Committee and Nominating Committee.

Robert E. Kane, 49, has served as the president, chief executive officer and owner of Reliant Holdings, Inc. since 2005, which provides credit related products and services to individuals that reside in all 50 states as well as the United Kingdom. Reliant Holdings' extensive operations include Internet marketing, e-commerce and mobile technology, call center services and fulfillment services. Over the past 10 years, Mr. Kane has served on the board of directors of numerous organizations including the Pennsylvania Economic Development Financing Authority (PEDFA), the Indiana County Chamber of Commerce, Indiana County Development Corporation and Indiana Regional Medical Center. Mr. Kane also served on S&T Bank’s Indiana Regional Advisory Board from 2012 to 2016. In addition to his sound leadership capabilities, Mr. Kane has attained a deep knowledge of the financial services industry throughout his career. We believe that Mr. Kane’s executive management experience and detailed knowledge of the financial and e-commerce sectors qualify him to serve on our Board.

David L. Krieger, 73, has served as a director of S&T since 2007. Mr. Krieger has been retired since 2007 but was formerly Senior Executive Vice President and Commercial Lending Group Manager of S&T and S&T Bank. We believe that Mr. Krieger’s 24 years of experience at S&T, including leading our commercial lending group, adds valuable experience to the S&T Board. Mr. Krieger has deep knowledge of our lending practices and our customer base, and his commercial lending experience, both at S&T and at his prior employer, provides the S&T Board with significant operational insights regarding credit risk.

James C. Miller, 71, has served as a director of S&T since 1993. Mr. Miller served as Chairman of S&T and S&T Bank from 2004 to 2013. Mr. Miller is retired but was formerly Chief Executive Officer of S&T and S&T Bank from 1998 until 2008 and President of S&T and S&T Bank from 1993 until 2005. We believe that Mr. Miller’s banking experience, including 37 years with S&T or a bank acquired by S&T and his service as our former chief executive officer, provides him with a unique perspective of our business, including our markets, customer base, senior management, key employees, potential customers, and operations and finances, and qualifies him to serve on the S&T Board.

Frank J. Palermo, 64, has served as a director of S&T since January 2013 and is Chairman of the Audit Committee and a member of the Nominating Committee. Mr. Palermo is a Certified Public Accountant and a Certified Valuation Analyst, and has been the managing shareholder of Palermo/Kissinger & Associates, P.C. since 1983. Mr. Palermo played an integral role in forming Gateway Bank of Pennsylvania (“Gateway”), where he served as chairman of the audit committee from its inception in 2004 through the date S&T acquired Gateway in 2012. Mr. Palermo’s career also includes 38 years in public accounting and four years as a vice president and controller at a community bank. We believe that Mr. Palermo’s background in accounting and finance, as well as his prior bank audit committee experience, bring a valuable perspective to the S&T Board both with respect to accounting, financial and strategic aspects of S&T’s business and to the Audit Committee on which he serves as “audit committee financial expert.” We further believe that Mr. Palermo’s extensive board experience qualifies him to be a member of the S&T Board and to serve on the Audit Committee and the Nominating Committee.

Christine J. Toretti, 60, has served as Vice Chairman of S&T and S&T Bank since 2013 and a director of S&T since 1984. Ms. Toretti is a member of the Nominating Committee. Ms. Toretti has been the president of Palladio, LLC since 2011, was the chairman and chief executive officer of S.W. Jack Drilling Company from 1990 through 2010 and was the president of The Jack Company from 1988 through 2015. Ms. Toretti has been the president of Plum Production, Inc. since 1991, and president of CJT, LLC since 2002, each of which is a natural gas investment company. Ms. Toretti has also been a board of director member for the EQT Corporation since October 2015. Ms. Toretti’s deep industrial and energy experience provides the S&T Board with a strategic outlook regarding lending and other commercial opportunities in these sectors, her experience of leading a family business allows her to offer the S&T Board valuable management perspective and credit risk assessment with respect to our industrial and oil and gas borrowers, and her board experience, including in the role of chairman, qualifies her to serve as Vice Chairman of the S&T Board and on the Nominating Committee.

Charles G. Urtin, 70, has served as Chairman of S&T and S&T Bank since 2013 and was formerly Vice Chairman of S&T and S&T Bank from 2008 to 2013. Mr. Urtin is a member of the Audit Committee. Mr. Urtin is retired but was formerly president and chief executive officer of IBT Bancorp, Inc. and Irwin Bank. We believe that Mr. Urtin’s 40 years of banking experience, including serving as chief executive officer of IBT Bancorp and Irwin Bank, provides the S&T Board with valuable industry, strategic, financial and operational insight, and his long-standing presence as a leader of a regional bank operating in our geographic market assists the S&T Board with customer acquisition, credit risk analysis and loan portfolio management and qualifies him to serve as the Chairman of the S&T Board and on the Audit Committee. Mr. Urtin assisted the S&T Board with transition and integration issues following our acquisition of IBT Bancorp in 2008.

Steven J. Weingarten, 58, has served as a director of S&T since March 2015 and is a member of the Compensation Committee and the Nominating Committee. Mr. Weingarten has been an attorney at McNees Wallace & Nurick LLC since 1989, and a member since 1993. Additionally, he served as managing partner of McNees Wallace & Nurick LLC from 2002 to 2006. Mr. Weingarten previously served on the board of Integrity from 2003 until it was acquired by S&T in March 2015. We believe that Mr. Weingarten’s experience in managing McNees Wallace & Nurick LLC and in practicing real estate law and the knowledge he gained from his service as a director of Integrity qualify him to serve on the S&T Board and on the Compensation Committee and the Nominating Committee.

Board Recommendation

THE S&T BOARD RECOMMENDS A VOTE “FOR ALL” OF THE NOMINEES.

CORPORATE GOVERNANCE

Corporate Governance Guidelines

The S&T Board has developed and adopted Corporate Governance Guidelines (“Guidelines”) which reflect S&T’s commitment to following corporate governance best practices. The Guidelines are intended to promote the functioning of the S&T Board and its committees and to set forth a common set of expectations as to how the S&T Board should perform its functions to enable effective corporate governance practices. These Guidelines are not intended to modify or amend S&T’s Articles of Incorporation, as amended (the "Articles of Incorporation") or By-laws. In the event of a discrepancy between these Guidelines and the Articles of Incorporation or the By-laws, the Articles of Incorporation and By-laws will always govern. The Guidelines are available on S&T’s website, www.stbancorp.com, under Corporate Governance.

Director Independence

The S&T Board determines annually that a majority of directors serving on the S&T Board are independent as defined in the NASDAQ listing rules. In 2016, the S&T Board also considered all direct and indirect transactions described under “Transactions with Related Parties” and “Compensation Committee Interlocks and Insider Participation” in determining whether a director is independent. Finally, the S&T Board considered whether a director has any other material relationships with S&T and concluded that none of S&T's directors has a relationship that impairs the director’s independence. There were no other related party transactions other than those described in the aforementioned sections of this Proxy Statement. The Nominating Committee has the delegated responsibility to evaluate each director’s qualifications for independence for the S&T Board and for the committees of the S&T Board. In accordance with the NASDAQ listing rules and interpretations, following review of the objective measures, the Nominating Committee and S&T Board also evaluate on a subjective basis each director’s personal, familial and/or business relationships, regardless of dollar amount.

On March 20, 2017, the S&T Board determined the following nine director nominees are independent under the NASDAQ listing rules: Mr. Donnelly, Mr. Grube, Mr. Hostetter, Mr. Jones, Mr. Kane, Mr. Palermo, Ms. Toretti, Mr. Urtin and Mr. Weingarten. As discussed below, all members of the Compensation Committee and the Nominating Committee are independent under the NASDAQ rules. In addition, the S&T Board determined that each of the members of the Audit Committee is independent under applicable SEC and NASDAQ rules.

Board and Committee Meetings

The S&T Board has implemented a formal policy that strongly encourages director attendance at the annual meeting of shareholders. In 2016, all of S&T’s directors attended the annual meeting of shareholders. Independent members of the S&T Board meet at least twice per year in regularly scheduled executive sessions with an independent Chairman of the Board presiding over all executive sessions.

During 2016, the S&T Board held 13 board meetings, with the following number of meetings held by the S&T Board committees: Audit, four; Compensation and Benefits, six; Credit Risk, four; Executive, three; Nominating and Corporate Governance, five; and Trust and Revenue Oversight, four. Each director attended at least 75% of the total number of meetings of the S&T Board and committees on which he or she served during 2016.

Board Structure; Separate Roles of Chairman and Chief Executive Officer

There are currently 14 directors comprising the S&T Board. The number, however, will be reduced by the S&T Board to 13 effective as of the date of the Annual Meeting. Directors Delaney and Gatti will retire immediately following the Annual Meeting. The S&T Board has established six committees: Audit, Compensation and Benefits, Credit Risk, Executive, Nominating and Corporate Governance, and Trust and Revenue Oversight.

The S&T Board believes that, as part of our efforts to embrace and adopt good corporate governance practices, different individuals should hold the positions of Chairman of the Board and Chief Executive Officer (“CEO”) to aid in the S&T Board’s oversight of management. The S&T Board believes that separation of the roles of Chairman and CEO is the best governance model for S&T and its shareholders at this time. Under this model, our Chairman, a non-executive position, can devote his attention to assuring that S&T has the proper governance controls in place; that the S&T Board is properly structured from the standpoints of membership, size and diversity; and that management has the support it needs from the S&T Board to carry out our strategic priorities. The CEO, relieved of the duties normally performed by the Chairman, is free to focus his entire attention on growing and strengthening the business.

The duties of the non-executive Chairman of the Board include:


•	presiding over all meetings of the S&T Board;


•	preparing the agenda for S&T Board meetings with the Corporate Secretary and in consultation with the CEO and other members of the S&T Board;


•	ensuring the S&T Board fulfills its role in overseeing and monitoring management and operations of S&T and protecting the interests of S&T and its shareholders;


•	ensuring the S&T Board receives timely, accurate and complete information and the decision time necessary to make informed judgments;


•	assigning tasks to the appropriate committees of the S&T Board;


•	establishing a relationship of trust with the CEO, providing advice and counsel while respecting the executive responsibilities of the CEO;


•	promoting effective relationships and open communication, both inside and outside the boardroom, between senior management and the S&T Board;


•	communicating the S&T Board’s evaluation of the CEO’s annual performance together with the Compensation Committee Chairperson; and


•	presiding over all meetings of shareholders.

We believe that the S&T Board, the S&T Board committees as presently constituted and the leadership structure of the S&T Board enable the S&T Board to fulfill its role in overseeing and monitoring the management and operations of S&T and to protect the interests of S&T and its shareholders.

The S&T Board’s Role in Risk Oversight

Role of the S&T Board

The S&T Board oversees an enterprise-wide approach to risk management (“ERM”), designed to support the achievement of strategic objectives, to improve long-term organizational performance and to enhance shareholder value. The S&T Board regularly discusses with our Chief Risk Officer (the “CRO”) our major risk exposures, their potential impact on S&T, and the steps we take to manage them. A fundamental part of risk management is not only understanding the risks a company faces in its current and future activities and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for a regional full-service financial institution. The S&T Board has ultimate responsibility for approving the risk appetite that is appropriate for S&T. The S&T Board delegates the authority and responsibility for defining the risk appetite and ensuring alignment with the strategic objectives to the management-level Enterprise Risk Management Committee (“Enterprise Risk Committee”). Under ERM, our business unit managers will identify and quantify the levels and types of inherent risk within their areas of responsibility, as well as consider the appropriateness of existing risk responses and controls for mitigating risks, based upon a standard definition of risk and risk mitigation established by the Enterprise Risk Committee. By utilizing a comprehensive and standardized view of the nature and level of risk to which we are exposed and the interaction of the various risk components identified in our ERM program, we are better able to assess and manage our risk and react to uncertainties.

Currently, the S&T Board administers its risk oversight function directly and through the Audit Committee, the Compensation Committee, the Credit Risk Committee, the Executive Committee, the Trust and Revenue Oversight Committee and the Enterprise Risk Committee (a management-level committee).

Pursuant to the terms of our Audit Committee charter, the CRO is accountable to both the Audit Committee and our CEO. The Audit Committee reviews and approves the appointment, replacement or dismissal of the CRO, and discusses the organizational structure and staffing regarding risk management, internal controls and regulatory compliance. In 2010, the Audit Committee engaged an independent consulting firm to provide a comprehensive approach to assisting the CRO in further developing an effective ERM process and environment that links corporate strategy and risk management. The independent consultant remains engaged in a co-sourcing arrangement to assist with the annual and quarterly ERM risk assessment process and to support the maintenance of a fully integrated ERM process.

The CRO, as the administrator of the ERM program, regularly meets with management, including the CEO, to discuss our various primary areas of risk identified as part of the ERM program, including credit matters and risks related to our loan and investment portfolios; liquidity and market risks; legal, regulatory and compliance risks; and operational, information technology, reputation and strategic risks. As necessary, the Audit Committee meets with the CRO to discuss and analyze risks to S&T without management present. The CRO makes a quarterly ERM presentation to the S&T Board and regularly reports on corporate governance, compliance and risk-related matters at other S&T Board meetings.

The Audit Committee is also responsible for monitoring our compliance risk with respect to regulatory and legal matters, and focuses on financial risk, including internal controls. The Audit Committee annually reviews and evaluates our internal audit function, and meets with our Chief Audit Executive (“CAE”) to review and assess internal audit risks including executive sessions without management present.

Our Enterprise Risk Committee, which is comprised of members of our senior management, including the CRO, CEO, Chief Financial Officer, Chief Operating Officer, Chief Credit Officer, Chief Banking Officer, CAE, Chief Lending Officer and General Counsel, meets quarterly to discuss the risk exposures of the enterprise, reviews changes to those exposures based on internal and external events, takes action to manage and mitigate such risks, discusses significant policy changes and new products/services, reviews ERM reports before presentation to the S&T Board and promotes proper risk management practices throughout S&T. A corporate policy approved by the S&T Board governs the Enterprise Risk Committee.

The Compensation Committee is responsible for assessing and mitigating risks associated with S&T’s compensation practices, both with respect to S&T’s Named Executive Officers (as further defined and described in the Compensation Discussion and Analysis section of this Proxy Statement) and its employees generally. The Compensation Committee reviews the incentive compensation arrangements for S&T’s Named Executive Officers with the CRO at least annually to discuss and evaluate the risk posed to S&T by its employee compensation plans and to ensure that the compensation arrangements do not encourage the Named Executive Officers to take unnecessary and excessive risks that threaten the value of S&T. The Compensation Committee meets quarterly or as often as it determines is necessary and appropriate.

Our Credit Risk Committee is responsible for reviewing the credit administration risk management practices and reporting; the performance of the independent loan review function and its assessment of the management of credit risk arising from the lending and lending related functions of S&T; the review of lending activity including a periodic review of portfolio concentrations that may be deemed to pose a heightened risk or larger loan relationships; credit policy approval; and providing guidance on pertinent credit risk matters including loan related strategies. The Credit Risk Committee meets quarterly or as often as it determines is necessary and appropriate.

Our Trust and Revenue Oversight Committee is responsible for the oversight of all trust activities consistent with the Federal Deposit Insurance Corporation’s Statement of Principles of Trust Department Management and the development and implementation of strategic and tactical initiatives in support of S&T’s revenue growth and shareholder value creation. The Trust and Revenue Oversight Committee meets quarterly or as often as it determines is necessary and appropriate.

The Executive Committee is responsible for coordinating S&T Board delegated risk oversight responsibilities across established S&T Board committees including monitoring industry developments and emerging risks and to exercise the authority to act on behalf of the S&T Board between meetings of the S&T Board to the fullest extent permitted by law. The Executive Committee meets at least annually or as often as it determines is necessary and appropriate.

Employee Compensation Policies and Managing Risk

We believe our approach to goal setting, setting of targets with payouts at multiple levels of performance, and evaluation of performance results assist in mitigating excessive risk-taking that could harm our value or reward poor judgment by our executives. We believe that several features of our compensation policies and programs reflect sound risk management practices, such as basing incentive awards on the achievement of a predetermined earnings per share (“EPS”) goal, an audited number, and the granting of restricted stock subject to a two or three year vesting that serves the additional purpose of encouraging senior management to make decisions currently that promote long-term growth and retention combined with stock ownership guidelines. All awards granted under the 2016 incentive plans were subject to Compensation Committee review and approval based upon corporate and/or individual performance. The incentive plan for senior management, as described in the "Compensation Discussion and Analysis" section below, contains a “Shareholder Protection Feature,” which provides that awards will not be made unless S&T maintains well capitalized capital ratio requirements, as established by applicable regulatory authorities. We believe we have allocated our compensation among base salary and short and long-term compensation target opportunities in

such a way as to not encourage excessive risk-taking. The Compensation Committee also reviews compensation and benefits plans affecting employees in addition to those applicable to executive officers. Based on the review by the Compensation Committee, the S&T Board determined that it is not reasonably likely that S&T’s compensation and benefit plans would have a material adverse effect on S&T.

Audit Committee

The members of the Audit Committee are Jeffrey Grube, Frank Jones, Frank Palermo (Chairman), and Charles Urtin. All members meet the independence standards for audit committees established by the SEC and NASDAQ. A written charter approved by the S&T Board governs the Audit Committee and includes the provisions required by the NASDAQ listing standards. A copy of the charter is included on S&T’s website www.stbancorp.com, under Corporate Governance. The Audit Committee has provided information regarding the functions performed by the Audit Committee and its membership in the “Report of the Audit Committee,” included in this Proxy Statement on page 46.

The S&T Board has determined that Mr. Palermo meets the qualifications of an audit committee financial expert under SEC regulations adopted under the Sarbanes-Oxley Act of 2002. Mr. Palermo is a Certified Public Accountant and Certified Valuation Analyst, with 38 years in public accounting, four years as a vice president and controller at a community bank and eight years as a director of a community bank. This experience and education give Mr. Palermo an understanding of U.S. generally accepted accounting principles and financial statements; the ability to assess general applications of such principles in connection with accounting for estimates, accruals and reserves; knowledge preparing, auditing, analyzing or evaluating financial statements presenting a breadth and level of complexity of accounting issues that are comparable to S&T’s financial statements; an understanding of internal control over financial reporting; and an understanding of audit committee functions. Mr. Palermo has been designated by the S&T Board as S&T’s “audit committee financial expert.”

Compensation and Benefits Committee

The members of the Compensation Committee are John Delaney, Michael Donnelly, Jeffrey Grube (Chairman), Jerry Hostetter and Steve Weingarten. The Compensation Committee’s function is to recommend to the S&T Board action on executive compensation and compensation and benefit changes brought to it by management. A written charter approved by the S&T Board governs the Compensation Committee. A copy of the charter is included on S&T’s website www.stbancorp.com, under Corporate Governance. The Compensation Committee is comprised entirely of independent board members, as defined by NASDAQ listing standards.

The Compensation Committee is responsible for our stated compensation strategies, goals and purposes, ensuring that there is a strong link between the economic interests of management and shareholders; that members of management are rewarded appropriately for their contributions to company growth and profitability; and that the executive compensation strategy supports organization objectives and shareholder interests. The Compensation Committee must provide clear direction to management to ensure that its policies and procedures are carried out in a manner that achieves balance and is consistent with safety and soundness. It approves any material exceptions or adjustments to the incentive compensation arrangements established for senior management, and carefully considers and monitors the effects of any approved exceptions or adjustments. It receives and reviews, on an annual or more frequent basis, an assessment by management, with appropriate input from risk management personnel, of the effectiveness of the design and operation of the organization’s incentive compensation system in providing appropriate risk-taking incentives. It also reviews periodic reports of incentive compensation awards and payments relative to risk outcomes. It ensures that the incentive compensation arrangements for S&T do not encourage employees to take risks that are beyond S&T’s ability to manage effectively. It also performs other related duties as defined in its written charter.

The process, policies and specific determinations of the Compensation Committee with respect to compensation of our Named Executive Officers for fiscal 2016 are described in greater detail in the Compensation Discussion and Analysis section of this Proxy Statement.

The Compensation and Benefits Committee Report is on page 32 of this Proxy Statement.

Nominating and Corporate Governance Committee

The members of the Nominating Committee are John Delaney, Michael Donnelly, Frank Jones (Chairman), Frank Palermo, Christine Toretti and Steve Weingarten. The Nominating Committee functions are to assist the S&T Board in annually reviewing the qualifications and independence of the members of the S&T Board and its various committees as well as the composition

and structure of the S&T Board; to review and make recommendations to the S&T Board as to its committee structure, functions and composition on a periodic basis; to oversee the annual assessment of the performance of the S&T Board and whether its committees are functioning effectively; to recommend director nominees to the S&T Board to submit for election by shareholders; and to provide guidance to the S&T Board on corporate governance issues. In addition, the Nominating Committee reviews all transactions with related parties, as further described on page 43 of this Proxy Statement. The Nominating Committee oversees the S&T Director Orientation Program and the continuing education programs for all directors. To assist in remaining current with their board duties and committee responsibilities, the S&T Board participates in the Bank Director’s Membership Program. This Program offers the directors access to the BankDirector.com online video training series, a wide range of in-person conferences, periodic hard copy and digital magazine, peer-based and webinar educational programs on corporate governance, committee duties, board leadership and industry developments.

A written charter approved by the S&T Board governs the Nominating Committee. A copy of the charter is included on S&T’s website www.stbancorp.com, under Corporate Governance. The Nominating Committee is comprised entirely of independent board members, as defined by NASDAQ listing standards.

Director Qualifications and Nominations; Board Diversity

The Nominating Committee has adopted, and the S&T Board has ratified, a corporate policy for identifying and evaluating candidates for membership on the S&T Board. The Nominating Committee identifies potential candidates based on suggestions from directors, officers of S&T and S&T shareholders. The Nominating Committee will consider shareholder nominations for directors in accordance with the procedure set forth in Section 202 of S&T’s By-laws and applicable law. The procedure provides that a notice relating to the nomination must be timely given in writing to the Corporate Secretary of S&T, at 800 Philadelphia Street, Indiana, Pennsylvania 15701, prior to the annual meeting. To be timely, the notice must be delivered not earlier than the close of business on the 120th day, nor later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting, unless the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, in which case notice must be delivered not earlier than the close of business on the 120th day prior to the date of such annual meeting and not later than the close of business on the later of the 90th day prior to the date of such annual meeting or, if the first public announcement of the annual meeting date is less than 100 days prior to such annual meeting date, the 10th day following the day on which public announcement of the date of such meeting is first made by S&T. Such notice must be accompanied by the nominee’s written consent to be named in the applicable proxy statement and contain information relating to the business experience and background of the nominee and the nominee’s holdings of S&T Common Stock and information with respect to the nominating shareholder. There are no differences in the manner in which the Nominating Committee evaluates candidates for membership on the S&T Board based on whether such candidate is recommended by a shareholder, the Nominating Committee, or by any other source.

In evaluating and selecting nominees to the S&T Board, the Nominating Committee takes into account all factors and criteria it considers appropriate, which includes but is not limited to the following: high personal and professional integrity; sound independent judgment and exceptional ability; business experience; area of residence in relationship to S&T’s geographic market; other directorship experience that would be beneficial to the S&T Board and management of S&T; diversity of experience relative to that of other S&T directors; diversity of age, gender, minority status and level and type of education; whether the candidate will be effective in serving the long-term interests of S&T’s shareholders; whether the candidate has sufficient time and energy to devote to the affairs of S&T; whether the candidate possesses a willingness to challenge and stimulate management and the ability to work as part of a team; whether the candidate meets the independence requirements of the NASDAQ listing standards; whether the candidate is free from conflicts of interest with S&T; and any other factors related to the ability and willingness of a new director to serve or an existing director to continue his or her service.

The Nominating Committee may engage a third party search firm to assist it in identifying director candidates, but the Nominating Committee did not do so in 2016. S&T did not receive any timely shareholder nominations for director for consideration for this Annual Meeting. Accordingly, S&T has not rejected or refused such candidates.

Shareholder Communications with Directors

Shareholders who desire to communicate with the S&T Board or a specific director should send any communication, in writing, to S&T Bancorp, Inc., 800 Philadelphia Street, Indiana, Pennsylvania 15701, ATTN: Corporate Secretary. Any such communication should state the number of shares beneficially owned by the shareholder. S&T’s Corporate Secretary will initially review all communications received in accordance with the Shareholders Communication Policy adopted by the S&T Board. The Corporate Secretary will relay all such communications to the appropriate director or directors on a periodic basis unless

the Corporate Secretary determines that the communication does not relate to the business or affairs of S&T or the functioning or constitution of the S&T Board or any of its committees; relates to routine or insignificant matters that do not warrant the attention of the S&T Board; is an advertisement or other commercial solicitation or communication; is frivolous or offensive; or is otherwise not appropriate for delivery to directors. The director or directors who receive any such communication will have discretion to determine whether the subject matter of the communication should be brought to the attention of the full S&T Board or one or more of its committees and whether any response to the person sending the communication is appropriate. Any such response will be made through S&T’s management and only in accordance with S&T’s policies and procedures and applicable laws and regulations relating to the disclosure of information. If the Corporate Secretary believes the communication may be a complaint relating to any questionable accounting, internal accounting controls or auditing matter (“Covered Matter”), the Covered Matter will be handled in accordance with Corporate Policy #609 - Complaints Regarding Accounting, Internal Accounting Controls or Auditing Matters (“Whistleblower Policy”). A copy of the Whistleblower Policy is included on S&T’s website www.stbancorp.com, under Corporate Governance.

Code of Conduct and Ethics

The S&T Board has adopted a Code of Conduct for directors, officers and employees, which is posted on S&T’s website www.stbancorp.com, under Corporate Governance. The Code of Conduct addresses the professional, honest and candid conduct of each director, officer and employee; conflicts of interest, disclosure process, and compliance with laws, rules and regulations (including insider trading laws); corporate opportunities, confidentiality and fair dealing; protection and proper use of company assets; and encourages the reporting of any illegal or unethical behavior. A waiver of the Code of Conduct for an executive officer or director of S&T may be made only by the S&T Board and must be promptly disclosed as required by SEC or NASDAQ rules. S&T will disclose any such waivers, as well as any amendments to the Code of Conduct, on S&T’s website. Shareholders may obtain a printed copy of the Code of Conduct by contacting the Corporate Secretary at the address previously provided.

PROPOSAL 2: RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2017

The Audit Committee of the S&T Board appointed the firm of KPMG LLP as its independent registered public accounting firm ("Independent Accountants"), to audit and report on S&T’s financial statements for the fiscal year ending December 31, 2017. Action by shareholders is not required by law in the appointment of Independent Accountants. However, the S&T Board considers this selection to be an important issue and, therefore, is submitting the selection of KPMG LLP for ratification by the shareholders. If the shareholders do not ratify this selection, the selection will be reconsidered by the Audit Committee.

KPMG LLP has no direct or indirect financial interest in S&T or in any of its subsidiaries, nor has it had any connection with S&T or any of its subsidiaries in the capacity of promoter, underwriter, voting trustee, director, officer or employee. Representatives of KPMG LLP will be present at the Annual Meeting and will be afforded an opportunity to make a statement if they desire to do so. It is also expected they will be available to respond to appropriate questions.

Fees Paid to Independent Registered Public Accounting Firm

During the fiscal years ended December 31, 2016 and December 31, 2015, KPMG LLP served as S&T’s Independent Accountants.

Fees for professional services provided by our Independent Accountants in each of the last two fiscal years in each of the following categories are:



	2016	2015
Audit Fees	$832,000	$939,862
Audit-Related Fees	48,950	0
Tax Fees	0	0
All Other Fees	1,650	1,650
	$882,600	$941,512

“Audit Fees” for 2016 and 2015 include fees for audit services associated with the annual audit, the reviews of S&T’s quarterly reports on Form 10-Q, accounting, consultations and SEC registration statements. The 2015 fees also include services rendered in connection with S&T Bank’s acquisition of Integrity Bank.

“Audit-Related Fees” for 2016 include fees billed for U.S. Department of Housing and Urban Development compliance procedures.

“All Other Fees” for 2016 and 2015 represent subscription fees for an accounting and auditing research tool.

Pre-Approval Policies and Procedures

The Audit Committee is responsible for the approval of all services performed by the Independent Accountants. All services provided by the Independent Accountants in 2016 were pre-approved by the Audit Committee. The Audit Committee is required to pre-approve all audit and non-audit services performed by the Independent Accountants to assure that the provision of such services does not impair the Independent Accountant’s independence. In addition, any proposed services exceeding pre-approved cost levels will require specific pre-approval by the Audit Committee. The Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated will report any pre-approval decisions to the Audit Committee at its next scheduled meeting for ratification. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the Independent Accountants to management.

Board Recommendation

THE S&T BOARD RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE SELECTION OF KPMG LLP AS S&T's INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2017.

PROPOSAL 3: ADVISORY VOTE TO APPROVE COMPENSATION

OF S&T’S NAMED EXECUTIVE OFFICERS

S&T believes that our overall executive compensation program, as described in the "Compensation Discussion and Analysis" section (the “CD&A”) elsewhere in this Proxy Statement, is designed to pay for performance and directly aligns the interest of our executive officers with the long-term interests of our shareholders.

As required by Section 14A of the Exchange Act, S&T is providing its shareholders a vote to approve, on a non-binding basis, the compensation of our Named Executive Officers (“NEOs”) as disclosed in this Proxy Statement in accordance with the SEC’s rules. This vote is not intended to address any specific item of compensation or the compensation of any particular officer, but rather the overall compensation of our NEOs and our compensation philosophy, policies and practices. Previously, pursuant to Section 14A of the Exchange Act, the S&T Board recommended, and the shareholders subsequently approved, that this advisory proposal be submitted to shareholders annually; accordingly, the next advisory vote will occur at next year's annual meeting of shareholders.

Accordingly, S&T is presenting the following advisory proposal, commonly known as the “say-on-pay proposal,” for shareholder approval:

“Resolved, that the shareholders hereby approve the compensation of our Named Executive Officers as reflected in this Proxy Statement and as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, which disclosure includes the compensation discussion and analysis, the compensation tables and all related material.”

Because your vote is advisory, it will not be binding upon the S&T Board. In the event this non-binding proposal is not approved by our shareholders, then such a vote shall neither be construed as overruling a decision by the S&T Board or the Compensation Committee, nor create or imply any additional fiduciary duty by the S&T Board or our Compensation Committee, nor further shall such a vote be construed to restrict or limit the ability of our shareholders to make proposals for inclusion in proxy materials related to executive compensation. Notwithstanding the foregoing, the S&T Board and the Compensation Committee will consider the non-binding vote of our shareholders on this proposal when reviewing compensation policies and practices in the future.

Board Recommendation

THE S&T BOARD RECOMMENDS A VOTE “FOR” APPROVAL OF THIS ADVISORY PROPOSAL ON COMPENSATION OF S&T's NAMED EXECUTIVE OFFICERS.

COMPENSATION DISCUSSION AND ANALYSIS

INTRODUCTION

We provide the following overview of S&T’s executive compensation principles, specific executive compensation programs and pay decisions that were made by the Compensation and Benefits Committee (the "Compensation Committee") in 2016 and early 2017. In addition, we describe the process that we oversee and in which we participate to arrive at specific compensation policies and decisions involving program design and pay for S&T’s Named Executive Officers (“NEOs”), who are listed below.



Name		Title
Todd Brice		President and Chief Executive Officer
Mark Kochvar		Senior Executive Vice President and Chief Financial Officer
David Antolik		Senior Executive Vice President and Chief Lending Officer
David Ruddock		Senior Executive Vice President and Chief Operating Officer
Ernest Draganza		Senior Executive Vice President and Chief Risk Officer

EXECUTIVE SUMMARY

S&T achieved the following major accomplishments during 2016:


•	Net income increased 6.4 percent to a record $71.4 million, or $2.05 per diluted share, compared to $67.1 million, or $1.98 per diluted share for 2015.


•	Return on average assets was 1.08 percent and return on average equity was 8.67 percent.


•	Strong organic loan growth of $583.8 million, or 11.6 percent.


•	Total deposits grew $395.8 million, or 8.1 percent.

During 2016, we successfully expanded our commercial banking operations by opening a new loan production office on the North Shore in Pittsburgh, Pennsylvania, and enhanced our presence in Northeast Ohio by relocating our banking facility in Akron, Ohio.

As disclosed in the Compensation Discussion and Analysis section from the proxy statement for the 2016 Annual Shareholders Meeting, we evaluated and approved the following pay adjustments and awards for NEOs for 2016:


•	Average salary increase of 3.9%.


•	An annual cash incentive award with a target of 35% and 30% of base salary for the CEO and the other NEOs, respectively, under the terms of the 2016 Management Incentive Plan (“2016 MIP”).


•	A long-term incentive award with a target of 40% and 35% of base salary for the CEO and the other NEOs, respectively, granted in the form of time and performance-based restricted shares under the terms of the 2016 Long-Term Incentive Plan (“2016 LTIP”).

For 2017, we evaluated and approved the following pay adjustments and awards for the NEOs:


•	Average salary increase of 2.6%.


•	An annual incentive award with a target of 35% and 30% of base salary for the CEO and the other NEOs, respectively, under the terms of the 2017 Management Incentive Plan (“2017 MIP”).


•	A long-term incentive award with a target of 40% and 35% of base salary for the CEO and the other NEOs, respectively, granted in the form of time and performance-based restricted shares under the terms of the 2017 Long-Term Incentive Plan (“2017 LTIP”).

SAY ON PAY AND SHAREHOLDER ENGAGEMENT

S&T is required to provide a separate non-binding shareholder advisory vote on the compensation of S&T’s NEOs. At the 2016 Annual Shareholder Meeting, the holders of 21,307,909 shares of Common Stock, or 95.1% of the shares voting on the proposal, voted to approve the non-binding, advisory proposal on the compensation of S&T’s executive officers. Because not all shareholders voted their shares, this amounted to 61.2% of the then outstanding shares of Common Stock.

The vote reflects support for S&T’s executive compensation policies and practices among shareholders. As a consequence, the Compensation Committee expects to continue to adhere to the compensation policies, principles and programs described below in future years.

OVERVIEW OF THE COMPENSATION PROGRAM FOR NAMED EXECUTIVE OFFICERS

S&T designs its management compensation programs to optimize their alignment with S&T’s strategic direction and business environment within which it must create value for shareholders. The primary program objectives have been and continue to be as follows:


•	The pay package is structured to cost efficiently attract, retain and reinforce engagement among the leadership team and S&T key contributors;


•	Compensation programs are aligned with shareholder interests for an appropriate balance between risk and reward;


•	Both individual plan features and the overall pay program are built on principles of sound risk management and effective controls critical to successful navigation of an uncertain environment for financial services companies; and


•	Reward programs are designed to emphasize adherence to strong pay for performance principles.

The Compensation Committee continues to support a pay program with four major program components to help guide compensation decisions:


•	Base Salary: A base salary position near the median of relevant competitive practices (i.e., calibrated to be consistent with base salary levels for comparable positions in other similar enterprises of similar scope).


•	Management Incentive Plan (“MIP”): An annual incentive plan with an incentive opportunity that is moderate relative to competitive practices for similar positions at potential competitors for talent. Target annual incentives should drive desired positioning for total compensation to the middle of the market.


•	Long-Term Incentive Plan (“LTIP”): A long-term incentive program that serves two purposes: (1) to help ensure leadership retention and management continuity as S&T continues to execute its longer-term strategic plan; and (2) to reward management for strong sustained value creation and financial performance.


•	Supplemental Benefits: Limited additional supplemental benefits that are either consistent with those provided to other employees, or directly created to reinforce a singular commitment from the management team to S&T and its business imperatives.

The Compensation Committee considers overall corporate performance as well as individual initiative and achievements when reviewing and approving all compensation decisions relating to S&T’s NEOs: the CEO, the CFO and the other executive officers named in the Summary Compensation Table on page 34 of this Proxy Statement. The policy of the Compensation Committee is to provide compensation that is competitive within the banking industry of financial institutions of similar size and product offerings.

The Compensation Committee is actively involved in the oversight of not only NEO compensation but all remuneration programs that have a material cost profile, that could materially affect S&T’s risk profile or influence the focus of key contributors on achievement of strategic and tactical objectives.

For NEOs, the Compensation Committee reviews a number of analyses of compensation practices to help facilitate its executive compensation decisions. These include:


•	Pay mix representing the effectiveness of balancing long-term versus short-term performance imperatives;


•	Wealth accumulation opportunities in light of existing programs and outstanding rewards;


•	Current pay relative to peer group practices;


•	Selective review of compensation data for positions of similar scope and focus; and


•	Detailed formal review of overall performance and specific performance contributions made to S&T by each NEO.

Total Direct Compensation Position

S&T’s target pay mix is built on competitive base salaries, with generally moderate annual and long-term incentive targets. The moderate positioning of annual incentives and long-term incentives reflects our commitment to introducing pay program modifications that are both sensitive to S&T’s proactive risk management culture while, at the same time, responding appropriately to the importance of retaining a strong and committed leadership team at S&T. The Compensation Committee reviews this posture periodically with the help of outside advisors, and continues to believe that the opportunities provided under the incentive plans reflect an appropriate balance between risk and reward, and provide sufficient incentives to align management to achieve S&T’s short-term and longer-term objectives.

COMPONENTS OF THE COMPENSATION PROGRAM

Base Salary

The purpose of base salary is to provide competitive and fair base compensation that recognizes the executives’ roles, responsibilities, contributions, experiences and performance. Base salary represents a fixed and guaranteed element of compensation that reflects executives’ long-term performance and market pay level for the role. S&T’s base salary policy targets the median of relevant competitive practices. Relevant competitive practices are determined using both a proprietary survey of pay practices at community and regional banks similar in size and scope to S&T and an examination of Peer Bank executive pay practices. The Peer Banks are listed on page 27 of this Compensation Discussion and Analysis (“CD&A”). The Compensation Committee sets each executive’s individual pay annually to reflect individual experiences, expertise, performance and contributions in the role. As such, actual base salaries range above and below the median of relevant competitive practices in recognition of these factors, including tenure in role, historical performance and specific bank needs.

Management Incentive Awards

The purpose of the MIP is to align management’s interests to the achievement of S&T’s financial, operational and strategic objectives for the year. The MIP provides senior management with an annual cash incentive opportunity designed to: (i) create focus on specific planned performance goals, (ii) deliver a portion of a competitive pay package in a form that is not fixed but varies in relation to the performance of S&T and (iii) serve as a vehicle for recruitment and retention.

For 2016, we adopted the 2016 MIP, with the following features:


•	The target annual incentive opportunity was 35% and 30% of base salary for the CEO and the other NEOs, respectively. The actual payout was 14% and 13% of base salary for the CEO and the other NEOs, respectively.


•	70% of each participant’s award was earned based on corporate results, and 30% was based on performance relative to individual/unit goals.


•	Corporate results were determined based on EPS and Deposit Growth (defined as the total net increase in customer deposits in the plan year).

•

Each participant had multiple individual goals against which individual performance was evaluated. The framework for establishing these goals was based largely on execution of elements of S&T’s strategic plan, including activities centered around multi-faceted growth, profit improvement, operational effectiveness, corporate culture, effective brand and enterprise risk management (i.e., balanced risk and reward).

The formula used to determine awards is defined as follows:

Award Earned

Calendar Year Base Salary

Target Incentive Opportunity as a % of Salary

S&T's Corporate Results To Goals Performance Factor

Individual Objectives Performance Factor

The corporate performance measures for 2016, EPS and Customer Deposit Growth, were each assigned specific weighting factors, and actual earnings opportunities for EPS were based on the Performance Level actually achieved relative to the performance ranges shown in the table below:



Performance Level		Payout Level Percentage
Below Threshold		0% of Allocated Target
Threshold		25% of Allocated Target
Target		100% of Allocated Target
Distinguished		150% of Allocated Target


•	Allocated Target equals the participant’s MIP incentive target multiplied by the weighting for each performance category (i.e., 60% for EPS, 10% for customer deposit growth, and 30% for individual objectives.)


•	The Payout Level Percentages relating to the EPS Performance Measure vary depending on Actual Performance, and its payout curve rises continuously from Threshold to Target and from Target to Distinguished. Therefore, to determine awards between Threshold and Target and Target and Distinguished, linear interpolation would be utilized.


•	The Customer Deposit Growth Performance Measure is an “all-or-nothing” performance standard in which 100% of the Allocated Target is earned only if the Target Performance Level is met.

To further strengthen the linkage between the MIP award, risk management and shareholder value creation, the MIP contains a “Shareholder Protection Feature” in which payouts will not occur for any plan year if S&T falls below “well capitalized” capital ratio requirements established by regulatory authorities, determined as of and up to the date that any payment would ordinarily occur pursuant to the MIP’s provisions. In addition to the Shareholder Protection Feature of the MIP, the MIP is operational only if S&T achieves Return on Average Equity (“ROAE”) for the plan year of at least 5% (the “Minimum Gateway Requirement”). The Compensation Committee believes that these features, coupled with the clawback requirements and the use of multiple performance measures, provide for substantial protection against excessive or unnecessary risk-taking by any plan participant.

The Compensation Committee has approved the 2017 MIP, which has similar provisions to the 2016 MIP. The corporate performance measures are each assigned specific weighting factors, and actual payouts will be based on the Performance Level actually achieved as follows:



Performance Level		Payout Level Percentage
Below Threshold		0% of Allocated Target
Threshold		25% of Allocated Target
Target		100% of Allocated Target
Distinguished		150% of Allocated Target


•	Allocated Target equals the participant’s MIP incentive target multiplied by the weighting for each performance category (i.e., 70% for EPS and 30% for individual objectives.)


•	The Payout Level Percentages relating to the EPS Performance Measure vary depending on Actual Performance, and its payout curve rises continuously from Threshold to Target and from Target to Distinguished. Therefore, to determine awards between Threshold and Target and Target and Distinguished, linear interpolation would be utilized.

Award opportunities for 2017 for the NEOs are shown in the table below and reflect the amount payable to NEOs if S&T were to achieve target financial results and the NEOs achieve 100% of their individual objectives for 2017.



Named Executive Officer	MIP Target % of Base Salary	MIP Target $ of Base Salary
Todd Brice, President and Chief Executive Officer	35%	$218,838
Mark Kochvar, Senior Executive Vice President and Chief Financial Officer	30%	100,710
David Antolik, Senior Executive Vice President and Chief Lending Officer	30%	111,540
David Ruddock, Senior Executive Vice President and Chief Operating Officer	30%	94,860
Ernest Draganza, Senior Executive Vice President and Chief Risk Officer	30%	92,760

Long-Term Incentive Plan

The LTIP is designed to: (i) create focus on specific long-term goals aligned with shareholder interests, (ii) deliver a portion of a competitive pay package in a form that is not fixed but varies in relation to the long-term performance of S&T and (iii) serve as a vehicle for recruitment and retention.

The 2016 LTIP included the following features:


•	The target incentive payout was 40% and 35% of base salary for the CEO and other NEOs, respectively.


•	The incentive payout is denominated in restricted stock by dividing the target incentive by a grant date share value.


•	One half of the shares will be earned based on remaining with S&T for three years (time-based restricted share awards vest equally on the second and third anniversaries of their grant date).


•	The other half will be earned based on performance relative to the Peer Banks and is referred to as the Performance-Based Restricted Share (“PBRS”) Target.

•

The number of PBRSs earned may rise to 150% of the PBRSs originally granted to a participant if Return on Average Equity performance is at the “distinguished” level (see below) and Total Shareholder Return is above half the Peer Banks. The number of PBRSs can fall to zero shares if performance is below the threshold level and Total Shareholder Return is below half the Peer Banks. If the number of shares earned exceeds the number of PBRSs issued to a participant (because performance is above target) S&T issues additional unrestricted shares upon vesting so that the participant receives the full number of shares earned.

The 2016 LTIP contains the same Shareholder Protection Feature and Minimum Gateway Requirement as described earlier for the 2016 MIP. The Compensation Committee believes that these features, coupled with the restricted stock and clawback requirements, provide for substantial protection against excessive or unnecessary risk-taking by any plan participant. The 2016 LTIP puts a greater focus on performance and serves to create a balance between long-term and short-term performance imperatives, beyond that offered by the annual cash incentive under the MIP.

Two metrics are used to determine the percentage of the PBRS Target earned through vesting of the PBRS awards (also referred to as performance shares):

(1) Return on Average Equity (“ROAE”) for 2016 through 2018 relative to Peer Banks

Participants can earn from 0% to 120% of their PBRS Target based on this metric as summarized below:



Performance Level	ROAE for 3-year Performance Period Relative to Peer Banks	Vesting Percentage ^(a)
Below Threshold	Below the 40^th percentile of the Peer Banks	0% of Target
Threshold	40^th percentile of the Peer Banks	25% of Target
Target	60^th percentile of the Peer Banks	100% of Target
Distinguished	75^th percentile of the Peer Banks	120% of Target

^(a)The Vesting Percentage for ROAE will vary depending on actual performance. The payout curve rises continuously from Threshold to Target and from Target to Distinguished. Therefore, to determine awards between Threshold and Target and Target and Distinguished, linear interpolation would be utilized.

(2) Cumulative Total Shareholder Return for 2016 through 2018 relative to Peer Banks

Participants can earn an additional 30% of their PBRS Target if S&T’s cumulative Total Shareholder Return (“TSR”) for the performance period exceeds the cumulative TSR for more than half of S&T’s peers (i.e. exceeds 50^th percentile of the Peer Banks).

The Compensation Committee has approved the 2017 LTIP, which has similar provisions to the 2016 LTIP, and has a performance period of January 1, 2017 through December 31, 2019.

Certain Other Benefits

S&T provides other benefits, or perquisites, to the NEOs that are comparable to the other benefits provided at the Peer Banks. The Compensation Committee believes that perquisites should be appropriately limited in scope and value. The primary perquisites for the NEOs are the company contributions to a qualified defined contribution plan and a nonqualified deferred compensation plan, a defined benefit program, a company car or car allowance, payment of the initiation fees and dues for social or country club memberships and a welfare benefit plan.

S&T maintains the Thrift Plan for Employees of S&T Bank (the “Thrift Plan”), which is a qualified defined contribution plan. All employees may participate in the Thrift Plan with elective salary deferrals, or 401(k) contributions. During 2016, S&T made matching contributions equal to 100% of the first 1% of the employees’ eligible compensation and 50% of the next 5% of the employees’ eligible compensation, up to a maximum of 3.5% of the employees’ eligible compensation. S&T considers the matching contributions to the Thrift Plan as an important incentive for employees to contribute toward their own retirement savings. In 2016, S&T made the following matching contributions to the Thrift Plan for each NEO: Mr. Brice, $9,275; Mr. Kochvar, $8,400; Mr. Antolik, $8,400; Mr. Ruddock, $9,275; and Mr. Draganza, $8,400.

S&T established the S&T Bancorp, Inc. Supplemental Savings and Make-Up Plan (the “Nonqualified Plan”) in 1995 in order to provide certain management employees, including executives, the ability to make up for certain benefits that would normally be provided under S&T’s qualified plans except for federal tax laws setting annual compensation limits for qualified plans and additional limitations related to highly-compensated employees. The Nonqualified Plan was amended for compliance with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations and other guidance promulgated thereunder (“Section 409A”) in December 2008, and again in 2012 to allow for employer discretionary contributions. S&T makes employer contributions to this plan that cannot be made to the qualified plans due to the aforementioned limits. During 2016, S&T contributed to the Nonqualified Plan for Mr. Brice $13,723; Mr. Kochvar, $0; Mr. Antolik, $6,586; Mr. Ruddock, $0; and Mr. Draganza, $0.

S&T maintains a defined benefit pension program for eligible employees hired before January 1, 2008, including NEOs hired before that date. The NEOs’ defined benefit pension benefit is determined from two sources: (1) the qualified defined benefit retirement plan; and (2) a nonqualified supplemental plan. The benefits provided under these two sources are described beginning on page 38 of this Proxy Statement. The value of such defined benefit pension benefits changes as compensation, service length, discount rate and mortality assumptions change. Consequently, the value credited to each NEO in the Summary Compensation Table on page 34 of this Proxy Statement as Change in Pension Value is a function of a number of assumptions required to calculate the present value of benefits. The present value of the pension can change without the accrual of additional benefits to the NEO, but as a result of a change in interest rates. For 2014, 49.5% of the increase in the Change in Pension Value amount shown in the Summary Compensation Table is attributable to a 75 basis point decrease in interest rates. For 2015 and 2016, the increase was primarily due to the accrual of additional service and increases in compensation. This increase in 2015 was partially offset by a 25 basis point increase in interest rates. On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the Retirement Plan and Nonqualified Plan effective March 31, 2016. This change resulted in no additional benefits being earned by participants in those plans based on service or pay after March 31, 2016.

S&T’s executives frequently drive vehicles on company business. Therefore, S&T provides either a company car or a car allowance to executives. Executives are responsible for reporting the amount of personal use of company cars to S&T, so that the taxable income from such use can be reported in the executives’ compensation. Executives who do not have a company car receive an annual car allowance of $6,000 or $7,200, depending upon the frequency that the executive drives. The car allowance is fully taxable compensation.

S&T pays for certain members of senior management to belong to one or more private clubs, if the member of management has significant customer contact and involvement in the community. S&T considers a social or country club to be an appropriate venue to entertain customers and to participate in various community functions. Expenses of a personal nature or related to a spouse are not paid by S&T.

Other benefits generally provided to all officers and full-time employees include the S&T Bank Welfare Benefit Plan. This plan has provisions for medical reimbursement, dental coverage, vision care coverage, long-term disability income, a flexible spending account, a health savings account and life insurance. If S&T hires or initiates a transfer of an employee, including an NEO, with special skills and requires a relocation of more than 35 miles, the employee may be eligible for reimbursement of the costs of house hunting trips, closing on the sale of the old home and the purchase of the new home, temporary living quarters

and moving household goods and furniture. In these circumstances S&T will also gross up taxable relocation reimbursements for federal taxes.

PROCESS FOR DETERMINING NAMED EXECUTIVE OFFICER COMPENSATION

Compensation Approval Process

Executive compensation decisions are made by the Compensation Committee. Each member of the Compensation Committee is a non-employee director and qualifies as an independent director under the NASDAQ listing standards. The Compensation Committee independently decides the compensation that S&T will pay the CEO. For the remaining executive officers, the CEO makes recommendations to the Compensation Committee, which reviews, approves or adjusts the recommendations. The Compensation Committee meets in an executive session to discuss and finalize its decisions regarding the CEO’s compensation. The S&T Board reviews all decisions relating to the compensation of executive officers, except for decisions about awards under the S&T Bancorp, Inc. 2014 Incentive Plan (the “2014 Plan”), the MIP and the LTIP, which are made solely by the Compensation Committee with input from the CEO on all other NEOs. The Compensation Committee may delegate to its chairperson such power and authority as the Compensation Committee deems to be appropriate, except such powers and authorities required by law or regulation to be exercised by the whole Compensation Committee or a subcommittee of at least two members.

The Compensation Committee operates under a written charter approved by the S&T Board, which it reviews, modifies as necessary and reaffirms on an annual basis. The Compensation Committee charter is available in the Corporate Governance section of our website at: www.stbancorp.com.

Role of the Executive Compensation Advisor to the Compensation and Benefits Committee

During 2014 and early 2015, the Compensation Committee engaged Aon Hewitt to serve as an advisor to the Compensation Committee for executive compensation, including compensation of the NEOs. The Compensation Committee has monitored the relationship with Aon Hewitt carefully and has determined that the advice provided on NEO pay meets the highest standards of internal and external defensibility for such advice and that Aon Hewitt is independent and that there were no conflicts of interest resulting from retaining Aon Hewitt for such engagement. In reaching these conclusions, the Compensation Committee considered the factors set forth in both SEC rules and NASDAQ listing standards. The Compensation Committee did not engage Aon Hewitt in 2016, but has engaged the firm for services in 2017.

Role of Management (CEO)

The Compensation Committee reviews and approves the salary of Mr. Brice, the President and Chief Executive Officer, annually. The salaries for the other NEOs are reviewed by Mr. Brice, and are presented for approval to the Compensation Committee on an annual basis, previously in December but in March for 2017. For 2014, 2015 and 2016, the Compensation Committee accepted the CEO’s salary recommendation for executives, including the NEOs.

Use of Competitive Data

The Compensation Committee reviews comparisons of the compensation programs established by peer banks for executives having similar responsibilities to S&T’s executives to establish competitive benchmarks for S&T’s compensation program. Aon Hewitt prepared the comparisons for 2014. The Compensation Committee retained the same peers in 2015 and 2016 as in 2014, due to its consideration that the peer banks continued to be appropriate. The peer banks are based on similar size and scope to S&T, operating both inside and outside S&T’s geographic market, and include the following banks for pay comparison purposes (collectively, the “Peer Banks”):



• 1st Source Corporation • BancFirst Corporation • Berkshire Hills Bancorp, Inc. • Chemical Financial Corporation • City Holding Company • Community Bank System, Inc. • First Busey Corporation • First Commonwealth Financial Corporation • First Merchants Corporation		• Independent Bank Corporation • NBT Bancorp, Inc. • Peoples Bancorp, Inc. • Renasant Corporation • Sandy Spring Bancorp, Inc. • Univest Corporation of Pennsylvania • Union First Market Bankshares • WesBanco, Inc. • WSFS Financial Corporation

PAY FOR PERFORMANCE

Pay for Performance Alignment

As described in the preceding discussions of the MIP and LTIP, the Compensation Committee approved incentive opportunities under the MIP and the LTIP for executives in 2016. The executives also continued to have opportunities to benefit from corporate financial performance through performance-based restricted stock awards under the 2014 and 2015 LTIPs.

2016 NAMED EXECUTIVE OFFICER COMPENSATION DECISIONS AND PERFORMANCE CONSIDERATIONS

The following summarizes the pay actions and decisions made for 2016 for each component of pay for each NEO.

Base Salary Decisions

When appropriate, the Compensation Committee increases base salaries both to ensure consistency with market competitive practices and to recognize the critical value of each senior executive’s management of S&T. In 2016 and 2017, the Compensation Committee approved salary increases that recognized each NEO’s success in 2015 and 2016, respectively, in executing our key strategic initiatives of loan growth, improving asset quality and expense control. The following table summarizes base salary decisions made for NEOs for 2016 and 2017.



Name	2015 Salary (Effective 1/01/2015)	2016 Salary (Effective 1/01/2016)	% Increase		2017 Salary (Effective 1/01/2017)	% Increase
Todd Brice	$585,000	$610,000	4.27	%	$625,250	2.50	%
Mark Kochvar	315,000	327,500	3.97	%	335,700	2.50	%
David Antolik	347,000	361,000	4.03	%	371,800	2.99	%
David Ruddock	298,000	308,500	3.52	%	316,200	2.50	%
Ernest Draganza	291,500	301,700	3.50	%	309,200	2.49	%

Summary of Management Annual Incentive Decisions for 2016 Performance

Our 2016 EPS result of $2.05 was at the Threshold Performance Level, resulting in a Payout Level Percentage of 25% of the 60% Allocated Target. The Customer Deposit Growth Performance Measure was not met; therefore, none of the 10% Allocated Target was earned. Based on achieving the Threshold Performance Level of EPS and the level of achievement of individual goals, but not achieving the Customer Deposit Growth Performance Goal, at its meeting on March 20, 2017, the Compensation Committee approved the following cash awards under the 2016 MIP to each NEO:



Named Executive Officer		Award
Todd Brice, President and Chief Executive Officer		$84,866
Mark Kochvar, Senior Executive Vice President and Chief Financial Officer		36,844
David Antolik, Senior Executive Vice President and Chief Lending Officer		48,735
David Ruddock, Senior Executive Vice President and Chief Operating Officer		39,565
Ernest Draganza, Senior Executive Vice President and Chief Risk Officer		39,372

The award amounts are disclosed in the Summary Compensation Table on page 34 of this Proxy Statement.

2016 Long-Term Incentive Awards

On March 21, 2016, the Compensation Committee awarded the NEOs equity denominated long-term incentive awards under the 2016 LTIP. Grants were made at a grant price equal to $25.65 per share, which was the average of the high and low price of S&T Common Stock for the ten trading days ending on the grant date. Each NEO’s target award consists of the following:


•	Half in the form of performance-based restricted shares which are earned over a three-year period based on return on average equity performance relative to S&T’s Peer Banks (identified on page 27 of this Proxy Statement); and


•	Half in the form of time-based restricted shares which vest in equal amounts on the second and third anniversaries of their grant date.

If an NEO terminates employment prior to full vesting of any incentive award under the 2016 LTIP for any reason other than death or disability, or retirement in the case of time-based restricted shares, the award, to the extent not previously vested, shall be forfeited.

The following awards were granted under the 2016 LTIP to the NEOs:



Named Executive Officer	Value of 2016 LTIP Award	Number of Time-Based Shares	Number of Performance-Based Shares
Todd Brice, President and Chief Executive Officer	280,606	4,757	4,756
Mark Kochvar, Senior Executive Vice President and Chief Financial Officer	131,821	2,235	2,234
David Antolik, Senior Executive Vice President and Chief Lending Officer	145,305	2,463	2,463
David Ruddock, Senior Executive Vice President and Chief Operating Officer	124,184	2,105	2,105
Ernest Draganza, Senior Executive Vice President and Chief Risk Officer	121,437	2,059	2,058

As of March 31, 2017 and projected as of December 31, 2017, NEOs have the following outstanding restricted shares under the 2014, 2015 and 2016 LTIPs:



Named Executive Officer	Outstanding Restricted Shares March 31, 2017	Outstanding Restricted Shares December 31, 2017
Todd Brice	24,663	17,548
Mark Kochvar	11,594	8,255
David Antolik	12,741	9,096
David Ruddock	10,949	7,791
Ernest Draganza	10,710	7,620

CHANGE IN CONTROL

Effective January 1, 2007, S&T began entering into change in control agreements with selected officers in senior management, including all the NEOs. These agreements were put in place to help ensure that S&T’s leadership team remains engaged and focused should the organization ever become the target of a change in control where their jobs or ongoing compensation could be at risk. On December 31, 2008, S&T restated these change in control agreements for the purpose of complying with the requirements of Section 409A. Effective April 7, 2015, S&T restated these change in control agreements to reflect current market practices. The primary terms and compensation payments contemplated by the agreements have been modified but now also include robust non-competition and non-solicitation provisions, one or both of which must be agreed to by the executive in order to receive the benefits provided. The agreements provide for the following compensation:

•

S&T’s CEO will receive (a) a lump sum payment of 300% of the sum of his base salary and target bonus and (b) a pro rated annual bonus (based on the NEO, target bonus) for the year of termination, payable in a lump sum if: (1) his employment is involuntarily terminated without cause within six months preceding a change in control; (2) his employment is involuntarily terminated without cause within three years following a “change in control” (as defined below); or (3) he terminates his employment for “good reason” (as defined below) within three years following a change in control.

•

Depending upon their date of promotion, the other NEOs will receive (a) a lump sum payment of 200% of his base salary and target bonus and (b) a pro rated annual bonus (based on the NEO, target bonus) for the year of termination, payable in a lump sum if: (1) the NEO’s employment is involuntarily terminated without cause within six months preceding a change in control; (2) the NEO’s employment is involuntarily terminated without cause within two years following a “change in control” (as defined below); or (3) the NEO terminates his employment for “good reason” (as defined below) within two years following a change in control.

•

Payments under the agreements shall be paid or provided (or commence to be paid or provided) within five (5) business days after the executive has satisfied the requirement that the executive sign an irrevocable release of all claims against S&T, subject to a six-month delay for compliance with Section 409A, if necessary. (See “Tax Considerations” below). The CEO and NEOs who receive either 300% or 200% of their salary and target annual bonus in a change in control will also be subject to twelve (12) month non-competition and non-solicitation covenants. Each agreement provides that if the executive’s employment is terminated without cause, or terminates for good reason, within the three or two years of a change in control, as applicable for that particular executive, he will also receive payments equal to the amount of money required to maintain health benefits under COBRA. These additional benefits will continue for three years for the President and CEO and for two years for the other NEOs. Each agreement provides that, in the event any benefit received by a NEO in connection with a change in control or in connection with the termination of the NEO’s employment whether pursuant to the agreement or any other plan, arrangement or agreement (collectively, the “Total Benefits”) would be subject to the excise tax imposed under Section 4999 of the Code (the golden parachute excise tax), then the Total Benefits will be reduced to the extent necessary so that no portion of the Total Benefits is subject to such excise tax.

The agreements define “good reason” as the occurrence of any of the following (without the executive’s consent) after a change in control:


•	A material diminution of the executive’s duties, authority or responsibility, or any material change in the geographic location at which the executive must perform services (in this case, a material change means any location more than 40 land miles from the location prior to the change in control);

•

A material breach of the obligation imposed under the agreement for S&T (or any successor) to (a) continue to provide the executive after a change in control with benefits substantially similar to those enjoyed by the executive under any of S&T’s pension, life insurance, medical, health and accident, disability or other welfare plans (but not including annual bonus or incentive or equity-based compensation plans) in which the executive was participating at the time of the change in control, unless the nature of the change in benefit levels is consistent with changes to benefits levels provided to employees at the same or equivalent level or title as the executive; (b) provide annual bonus and incentive compensation opportunities that are not less favorable than provided prior to the change in control; or (c) provide the executive with the number of paid vacation days to which the executive is entitled to on the basis of years of service with S&T in accordance with S&T’s normal vacation policy in effect at the time of a change in control;


•	A material breach of the obligation imposed under the agreement that the agreement be binding upon any successor to S&T; or


•	A reduction of more than 10% in the executive’s annual base salary by S&T.

An executive cannot terminate for “Good Reason” unless (a) the executive shall have given written notice of such event to S&T within ninety (90) days after the initial occurrence thereof, (b) S&T shall have failed to cure the situation within thirty (30) days following the delivery of such notice (or such longer cure period as may be agreed upon by the parties), and (c) the executive terminates employment within six (6) months after the initial notification of the event constituting Good Reason.

A “change in control” is defined in the agreements as the occurrence of any of the following:

•

Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act in effect on the execution date of the agreement), other than a pension, profit-sharing or other employee benefit plan established by S&T, that is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act in effect as of the date first written above), directly or indirectly, of securities of S&T representing twenty- five percent (25%) or more of the combined voting power of the S&T’s then outstanding securities;

•

During any period of two consecutive years, individuals who at the beginning of such period constitute the S&T Board cease for any reason to constitute at least a majority thereof, unless the election of each director who was not a director at the beginning of such period has been approved in advance by directors representing at least a majority of the directors then in office who were directors at the beginning of the period;

•

The consummation of a merger or consolidation of S&T with any other corporation, other than a merger or consolidation which would result in the voting securities of S&T outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least fifty percent (50%) of the total voting power represented by the voting securities of S&T or such surviving entity outstanding immediately after such merger or consolidation;


•	The shareholders of S&T or the S&T Board approve a plan of complete liquidation or an agreement for the sale of or disposition (in one transaction or a series of transactions) of all or substantially all of S&T’s assets; or


•	Any other event that constitutes a change in control of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Exchange Act or any successor provision.

The agreements specifically exclude public stock offerings by S&T and convertible debt offerings by S&T from the definition of “change in control.”

The Compensation Committee believes that the agreement provides reasonable protection to the individual members on the senior management team and thereby aligns senior management’s interest with the interest of S&T’s shareholders.

OTHER COMPENSATION-RELATED PROVISIONS

Stock Ownership Guidelines

The Compensation Committee continues to believe that stock ownership in S&T is important to align shareholder and management interests. On December 17, 2007, the Compensation Committee adopted stock ownership guidelines for certain executives, including the NEOs, beginning on January 1, 2008. Under the guidelines, the CEO, senior executive vice presidents, executive vice presidents and senior vice presidents should own Common Stock having a market value equal to the following multiple of the individual’s base salary:



Role		Multiple of Fair Market Value of Common Stock
President and Chief Executive Officer		3X
SEVPs		2X
EVPs and SVPs		1X

Currently, Messrs. Brice, Kochvar, Antolik, Ruddock and Draganza meet the ownership guidelines. The guidelines do not establish a deadline for compliance with the stock ownership requirements; however, the Compensation Committee established additional guidelines that limit senior management to the right to liquidate only the number of the vesting restricted shares of Common Stock sufficient for paying current tax liabilities on the vesting shares, until the officer achieves the stock ownership guidelines.

Claw-Back Feature

The Compensation Committee adopted a claw-back feature in 2010. All payments are subject to claw-back provisions that can result in the awards being canceled or prior payments recouped. These claw-back provisions allow S&T to “claw back” any bonus, retention award or incentive compensation paid (or under a legally binding obligation to be paid) to an NEO or any of our next 20 most highly-compensated employees if the payment was based on materially inaccurate financial statements or any other materially inaccurate performance metric criteria.

Risk Mitigation in Plan Design

The Compensation Committee considers, in establishing and reviewing the executive compensation program, whether the program encourages any unnecessary or excessive risk taking and concludes:


•	S&T’s compensation plans do not encourage executives to take unnecessary and excessive risks that could threaten the value of S&T;


•	The compensation plans are structured so that their potential for generating unacceptable risk that could materially affect the value of S&T is limited; and


•	The compensation plans are not structured to create substantial opportunities to benefit due to material manipulation of financial results.

In addition, at least annually, the Compensation Committee discusses, evaluates and reviews with S&T’s CRO the compensation arrangements to ensure that: (i) the compensation plans for senior management (senior vice presidents or higher) do not encourage the members of senior management to take unnecessary and excessive risks that threaten the value of S&T, (ii) the compensation plans for employees do not pose unnecessary risks to S&T, and (iii) the compensation plans for employees do not encourage the manipulation of reported earnings to enhance the compensation of any of S&T’s employees.

Employment Agreements

S&T does not provide employment agreements for any of the NEOs. S&T believes in a policy of “at will” employment arrangements.

EFFECT OF TAXATION ON COMPENSATION PROGRAMS (TAX CONSIDERATIONS)

Code Sections 162(m) and 409A

The Compensation Committee believes that it has structured the compensation program to comply with Code Sections 162(m) and 409A. Section 162(m) of the Code generally denies a deduction to any publicly held corporation for compensation paid to its chief executive officer and its three other highest paid executive officers (other than the chief financial officer) to the extent that any such individual’s compensation exceeds $1 million.

“Qualified performance-based compensation” (as defined for purposes of Section 162(m)) is not taken into account for purposes of calculating the $1 million compensation limit, provided certain disclosure, shareholder approval and other requirements are met. The Compensation Committee is monitoring the effects of S&T’s compensation programs with regard to Section 162(m). To date, S&T has not suffered a loss of compensation deduction as a result of the $1 million limitation, and the Compensation Committee intends to take actions to minimize S&T’s exposure to nondeductible compensation expense under Section 162(m) of the Code. While keeping this goal in mind, however, the Compensation Committee reserves the right to maintain flexibility with respect to S&T’s executive compensation programs, including the awarding of compensation that may not be deductible when it believes that such payments are appropriate and in the best interests of the shareholders.

Gross-ups and IRC Section 280G

S&T does not provide any tax gross-ups to any NEOs or any other employee that may have the right to a payment upon a change in control.

COMPENSATION AND BENEFITS COMMITTEE REPORT

We, the Compensation and Benefits Committee (the “Compensation Committee”) of the Board of Directors of S&T Bancorp, Inc. (“S&T”), have reviewed and discussed the Compensation Discussion and Analysis included in this Proxy Statement with S&T’s management, and, based on such review and discussion, have recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and S&T’s Annual Report on Form 10-K for the year ended December 31, 2016.

Review of Risk Associated With Compensation Plans

In accordance with S&T corporate policy, the Compensation Committee reviewed the incentive compensation arrangements for senior management (senior vice president and higher) with S&T’s Chief Risk Officer and personnel acting in a similar capacity, to ensure that these incentive compensation arrangements do not encourage members of senior management to take unnecessary and excessive risks that threaten the value of the institution. The Compensation Committee meets annually with the Chief Executive Officer, Chief Risk Officer and the Director of Human Resources to, among other things:


1.	Discuss the long-term and short-term risks that the bank faces that could threaten the value of S&T;


2.	Identify the features of S&T’s incentive compensation arrangements that could lead members of senior management to take such risks or focus on short-term results and how to limit those features; and


3.	Review the employee compensation plans and eliminate features in those plans that could encourage manipulation of reported earnings.

The Compensation Committee reviewed the following senior management compensation plans and employee compensation plans: the 2016 Management Incentive Plan (“2016 MIP”); the 2016 Long-Term Incentive Plan (“2016 LTIP”); the 2016 Employee Incentive Plan (“2016 EIP”); the Commercial Banker Incentive Plan, an incentive for commercial lending employees based on loan fee income and new deposits generated; and 34 other employee incentive compensation plans which were determined by the Compensation Committee to be low risk.

On March 21, 2016, the Compensation Committee approved the 2016 MIP, the 2016 LTIP and the 2016 EIP. The purpose of the 2016 MIP was to provide senior management with an annual incentive opportunity designed to: (i) create focus on specific planned performance goals, (ii) deliver a portion of a competitive pay package in a form that was not fixed but varies in relation to the performance of S&T and (iii) serve as a vehicle for recruitment and retention. The 2016 MIP provided for an annual incentive based on individual performance and S&T’s financial performance relative to goals for earnings per share ("EPS") and for Customer Deposit Growth. The target annual incentive payout was based on a percentage of base salary, as follows: the Chief Executive Officer, 35%; Senior Executive Vice President, 30%; Executive Vice President, 20%; and Senior Vice President, 10%. For the Chief Executive Officer, Senior Executive Vice Presidents and Executive Vice President, 70% of each participant’s award was earned based on corporate results (60% EPS and 10% Customer Deposit Growth), and 30% was based on performance relative to individual goals. For Senior Vice Presidents, each participant’s award was based 50% on corporate results (40% EPS and 10% Customer Deposit Growth) and 50% on performance relative to individual goals.

For 2016, the Compensation Committee determined that S&T achieved the threshold level of $2.05 for its EPS financial performance goal with an EPS of $2.05, but Customer Deposit Growth was under the goal of $570 million. Since S&T met the “Shareholder Protection Feature” (i.e., exceeded the “well-capitalized” capital ratio requirement) and the “Minimum Gateway Requirement” (at least 5% return on average equity, or "ROAE"), the Compensation Committee determined that payments would be made under the 2016 MIP for its EPS financial performance for the 2016 fiscal year. The Compensation Committee also reviewed senior management’s performance relative to individual goals and approved payments for achievement of those individual goals.

The 2016 LTIP provides senior management with a long-term incentive opportunity designed to: (i) create focus on specific long-term goals aligned with shareholder interests, (ii) deliver a portion of a competitive pay package in a form that is not fixed but varies in relation to the long-term performance of S&T and (iii) serve as a vehicle for recruitment and retention. The target incentive is based on a percentage of base salary, as follows: Chief Executive Officer, 40%; Senior Executive Vice President, 35%; Executive Vice President, 25%; and Senior Vice President, 10%. The incentive is in the form of shares of restricted stock equal to the target incentive divided by a grant date share value. One half of the shares will be earned based on remaining with S&T for two to three years (time-based restricted share awards). The other half will be earned based on S&T’s ROAE performance over a three-year period compared to the Peer Banks (performance-based restricted share awards). The number of performance-

based restricted share awards earned may rise to 120% of the target number of shares or shrink to zero shares based on performance. Participants can earn an additional 30% of their target incentive if S&T’s cumulative Total Shareholder Return (“TSR”) for the performance period exceeds the cumulative TSR for more than half of S&T’s Peer Group (i.e., exceeds the 50th percentile of the Peer Group). The maximum payout of performance-based restricted share awards under the 2016 LTIP is 150% of the target incentive for such awards. Payments to the NEOs will be made in the form of shares of long-term restricted stock subject to vesting requirements and transferability restrictions. Payments are also subject to claw-back provisions, whereby a payment may be recovered by S&T if it was based on materially inaccurate financial statements (which includes, but is not limited to, statements of earnings, revenues, or gains) or any other materially inaccurate performance metric. The LTIP contains the same Shareholder Protection Feature and Minimum Gateway Requirement as the 2016 MIP as described above. The Compensation Committee believes that these features, coupled with the restricted stock and claw-back requirements, provides for substantial protection against excessive or unnecessary risk-taking by any plan participant.

The 2016 EIP provided a cash incentive opportunity to all employees under the level of senior vice president, based on the achievement of a predetermined EPS goal that the Compensation Committee approved. The employees earn a percentage of their eligible compensation. The EPS goals and incentive percentages for 2016 were: $2.05 for a 1% incentive, $2.20 for a 2% incentive, and $2.35 and above for a 3% incentive. Eligible employees earned a 1% incentive for 2016, since S&T achieved an EPS of $2.05. The Compensation Committee implemented the 2017 Employee Incentive Plan, which is substantially similar to the 2016 EIP and is based on EPS goals.

After a careful evaluation of all employee incentive plans, the Committee concluded:


•	S&T’s incentive compensation plans do not encourage members of senior management to take unnecessary and excessive risks that could threaten the value of S&T;


•	The incentive compensation plans are structured so that their potential for generating unacceptable risk that could materially affect the value of S&T is limited; and


•	The incentive compensation plans are not structured to create substantial opportunities to benefit due to material

⁽¹⁾ These columns present the range of estimated payouts under the 2016 MIP. For the MIP, the payments assume that the NEOs earned the individual component according to their actual individual goal achievement in 2016, with the corporate component being the performance measure affecting the range of estimated payouts. The actual awards were paid on March 20, 2017 and are in the Summary Compensation Table for Fiscal Year 2016 in the Non-Equity Incentive Plan Compensation column. The actual awards were at Threshold for the EPS corporate measure, and the Deposit Growth measure was not achieved. For a more detailed description of the 2016 MIP see “Management Incentive Awards” in the “Compensation Discussion and Analysis” on page 22.

⁽²⁾ On March 21, 2016, the Compensation Committee granted restricted stock at a grant price of $25.65, which was the average of the high and low price of S&T Common Stock for the ten trading days ending on the grant date, to the NEOs, and is in the Summary Compensation Table for Fiscal Year 2016 in the Stock Awards column. The grants were in accordance with the 2016 LTIP, pursuant to the Compensation Committee’s authority under the 2014 Plan. For a more detailed description of the 2016 LTIP, see “Long-Term Incentive Plan” in the “Compensation Discussion and Analysis" on page 24. These columns present one half of the shares granted, which are earned based on S&T’s ROAE and TSR performance measured against the Peer Banks over a three year period, 2016 through 2018. The range of estimated payouts are denominated in the number of shares that may be earned under the performance award.

⁽³⁾ This column presents one half of the aforementioned grant under the 2016 LTIP that will be earned based on remaining with S&T for three years.

The present values shown above are based on benefits earned as of December 31, 2016 under the terms of the Employees’ Retirement Plan of S&T Bank (the “Retirement Plan”) and the S&T Bancorp, Inc. Supplemental Savings and Make-up Plan (the “Nonqualified Plan”) as summarized below. Present values are determined in accordance with the assumptions used for purposes of measuring S&T Bank’s pension obligations under ASC 715 as of December 31, 2016, including a discount rate of 4.00%, with the exception that benefit payments are assumed to commence at age 62, the earliest age at which unreduced benefits are payable. Mr. Kochvar was eligible to retire as of December 31, 2016 and receive 72.92% of his benefits based on the reduction for early retirement described below. Mr. Ruddock was eligible to retire as of December 31, 2016 and receive 66.67% of his benefits based on the reduction for early retirement described below.

On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the Retirement Plan and Nonqualified Plan effective March 31, 2016. This change resulted in no additional benefits being earned by participants in those plans based on service or pay after March 31, 2016.

Employees’ Retirement Plan of S&T Bank

The Employees’ Retirement Plan of S&T Bank (“Plan”) is a defined benefit pension plan that covers substantially all employees hired prior to 2008. The Plan provides benefits that are based on years of service and compensation. Benefits payable under the Plan at normal retirement, age 65, are determined under the following formula.

1.0% of Average Final Compensation up to Covered Compensation, times Benefit Service

Plus

1.5% of Average Final Compensation in excess of Covered Compensation, times Benefit Service

For purposes of determining the normal retirement benefit, the terms used above have the following meanings:

•

Average Final Compensation is the average compensation received during the highest five consecutive years out of the last 10 years prior to retirement or termination of employment. Compensation generally means total cash remuneration determined before reductions for employee contributions for 401(k) or other pre-tax benefits, but does not include amounts deferred under the S&T Bancorp, Inc. Supplemental Savings and Make-up Plan. Compensation is limited each year as required by Federal law (limit was $265,000 for 2016). Average Final Compensation was frozen effective March 31, 2016.


•	Covered Compensation is the average of the Social Security taxable wage bases in effect for each year in the 35-year period ending with the calendar year in which a participant retires or terminates employment. Social Security Covered Compensation used to determine the normal retirement benefit was frozen effective March 31, 2016.


•	Benefit Service generally means an employee’s period of employment with S&T Bank after attainment of age 21. Benefit Service was frozen effective March 31, 2016.

Participants’ benefits under the Plan are 100% vested after completion of five years of service. Participants who terminate employment prior to age 55 with a vested benefit are entitled to receive their full accrued benefit at normal retirement, age 65, or upon election, can receive actuarially reduced benefits as early as age 55. Participants who terminate employment after age 55 with at least 10 years of service are eligible to receive early retirement benefits under the Plan. For participants who met certain age and service requirements as of December 31, 2007, early retirement benefits are reduced 5/12 of 1% for each month by which the date benefit payments commence precedes age 62. For participants who did not meet these requirements, early retirement benefits are reduced 5/12 of 1% for each month by which the date benefit payments commence precedes age 65.

Accrued benefits under the Plan are payable in the form of a 10-year certain and life annuity that provides equal monthly payments for the participant’s life with a minimum of 120 monthly payments guaranteed. Married participants must receive their benefit in the form of a 50% joint and survivor annuity with 120 monthly payments guaranteed unless their spouse consents to a different form of a payment. A 50% joint and survivor annuity provides a reduced monthly payment for the participant’s life with 50% of the payment continuing for the spouse’s life following the participant’s death. Various optional annuity forms of payment are available under the Plan, including a single lump sum payment. All forms of payment are actuarially equivalent in value.

S&T Bancorp, Inc. Supplemental Savings and Make-up Plan

As noted above under the definition of Average Final Compensation for the Employees’ Retirement Plan of S&T Bank, compensation deferred under the S&T Bancorp, Inc. Supplemental Savings and Make-up Plan (the “Nonqualified Plan”) is not included as eligible compensation and includable compensation is limited as a result of maximums imposed by law. The Nonqualified Plan restores benefits that are not payable by the Retirement Plan as a result of the executive’s election to defer compensation or as a result of the compensation limit. The provisions described above for the Retirement Plan apply to this plan as well, with the exception that upon termination or retirement participants automatically receive their benefit in the form of an actuarially equivalent lump sum, which is credited to their account under this plan and paid out in accordance with their distribution election.

Nonqualified Deferred Compensation

The following table provides information with respect to the Nonqualified Plan and the NEOs. The amounts shown include compensation earned and deferred in prior years, and earnings on, or distributions of, such amounts.



Name	Executive Contributions in Last Fiscal Year ($)	Registrant Contributions in Last Fiscal Year ($) ⁽¹⁾	Aggregate Earnings in Last Fiscal Year ($)	Aggregate Withdrawals/ Distributions ($)	Aggregate Balance at Last Fiscal Year End ($)

Ernest Draganza	0	0	2,316	0	21,065

⁽¹⁾ The amounts in this column have been included in the “All Other Compensation” column of the Summary Compensation Table on page 35.

The Nonqualified Plan offers certain management employees, including the NEOs, the opportunity to continue to defer income on a tax deferred basis that exceeds annual contribution or compensation limits for qualified plans. In addition, the Nonqualified Plan can be used by highly-compensated employees who are limited to the salary deferral limit to the Thrift Plan. The employee may elect to defer a percentage of compensation from each payroll under the Supplemental Savings provision. The employee may also elect to contribute at the same deferral rate as for the Thrift Plan after reaching a contribution or compensation limit under the Make-up provision.

S&T Bank makes employer matching and year end profit sharing contributions to the Nonqualified Plan that cannot be made to the qualified plans due to the aforementioned limits. The match is 3.5% of the deferral amount, except the match on deferrals under the Make-up provision, which are matched 100% of the first 1% of the employee’s eligible compensation and 50% of the next 5% of the employee’s eligible compensation, up to 3.5% of the employee’s eligible compensation. The year end profit sharing bonus is at the same percentage as for the Thrift Plan and applies to eligible compensation that exceeds the compensation limit for qualified plans.

The participants may elect the allocation percentages for employee deferrals and employer contributions into two large capitalization mutual funds, a balanced fund and a money market mutual fund in a Rabbi Trust. The Thrift Plan Committee at S&T Bank determines the investment vehicles in the Rabbi Trust, which currently are Vanguard 500 Index Fund Admiral, Fundamental Investors Fund Class R5, Dodge & Cox Balanced Fund and Federated Prime Obligations Fund.

As described earlier, distributions from the Nonqualified Plan are in accordance with the participant’s distribution election. The Nonqualified Plan is subject to the provisions of Section 409A of the Code.

Termination of Employment and Change-in-Control Arrangements

As described above, our NEOs do not have employment agreements. The NEOs would receive payments from S&T in connection with a termination from employment pursuant to their change-in-control agreements. The amount of the payment would vary, depending upon whether the termination was due to resignation, retirement, severance, good cause or change in control of S&T. In the event of death, the NEO’s beneficiary, heirs or estate would be entitled to certain payments.

Resignation. There are no employment agreements between S&T and any of the NEOs; therefore, in the event of resignation, the NEO would receive salary payments and participate in S&T’s benefit plans through the date of separation from employment. There would be no additional payments.

Retirement. Upon retirement, the NEOs would receive pension benefits as described above in the “Retirement Plan” and the “Nonqualified Plan.” Married participants must receive their benefit in the form of a 50% joint and survivor annuity with 120 monthly payments guaranteed unless their spouse consents to a different form of a payment. Various optional annuity forms of payment are available under the Retirement Plan, including a single lump sum payment. All forms of payment are actuarially equivalent in value. The NEO's time-based restricted stock may vest at the discretion of the Compensation Committee.



	The Retirement Plan			The Nonqualified Plan, Lump Sum Benefit as of 1/1/2016 ⁽³⁾
	Date Payable⁽¹⁾	Annual Benefit ⁽²⁾		The Nonqualified Plan, Lump Sum Benefit as of 1/1/2016 ⁽³⁾
Todd D. Brice	age 65		$102,900		$683,300
Mark Kochvar	1/01/2017	57,600		207,500
David G. Antolik	age 65	84,900		118,300
David P. Ruddock	1/01/2017	67,200		193,300
Ernest J. Draganza	age 65	67,200		67,500

⁽¹⁾ Messrs. Kochvar and Ruddock were eligible to retire and receive 72.92% and 66.67%, respectively, of their benefit payable on January 1, 2017 as described in "The Retirement Plan" above. Messrs. Brice, Antolik, and Draganza were not eligible for early retirement as of December 31, 2016, and are presented at what their respective benefit would be upon retirement at age 65 if they had terminated employment on December 31, 2016.

⁽²⁾ The NEOs are married participants and must receive their benefit in the form of a 50% joint and survivor annuity with 120 monthly payments guaranteed unless their spouse consents to a different form of a payment. The annual benefits shown in this column are payable for the participant’s life with a minimum of 120 monthly payments guaranteed. After 120 monthly payments have been made, 50% of the amount shown continues for the spouse’s life following the participant’s death. If the NEO became deceased prior to retiring, the NEO's surviving spouse would receive the amount shown for ten years commencing as of the date shown, reducing to 50% of the amount shown after ten years and continuing for the remainder of her lifetime.

⁽³⁾ The NEO receives a lump sum payment upon retirement or termination as described above in the “Nonqualified Plan." The lump sum payment is determined as the present value of a ten-year certain and life annuity based on an interest rate of 8.0% and a mortality table specified by the terms of the plan, and is deposited into the NEO's Nonqualified Plan deferred compensation account. Currently, the NEOs have elected to receive a lump sum distribution at age 70, but may change their elections to an earlier date, for the amount of their payments accrued prior to January 1, 2005. The NEOs individually elected a time and form of payment for payments accrued after December 31, 2004, as allowed by the Nonqualified Plan and permitted by Section 409A.

Severance, constructive termination and change in control. As described in the CD&A, during 2016, S&T had change in control agreements in effect with each of the NEOs. The agreement for Mr. Brice provided that he will receive (a) a lump sum payment of 300% of the sum of his base salary and target bonus and (b) a pro rated annual bonus (based on the NEO, target bonus) for the year of termination, payable in a lump sum if: (1) his employment is involuntarily terminated without cause within six months preceding a change in control; (2) his employment is involuntarily terminated without cause within three years following a “change in control” (as defined above); or (3) he terminates his employment for “good reason” (as defined below) within three years following a change in control. Each agreement for the other NEOs provides that he will receive (a) a lump sum payment of 200% of the sum of his base salary and target bonus and (b) a prorated annual bonus (based on the NEO, target bonus) for the year of termination, payable in a lump sum if: (1) the NEO’s employment is involuntarily terminated without cause within six months preceding a change in control; (2) the NEO’s employment is involuntarily terminated without cause within two years following a “change in control” (as defined above); or (3) the NEO terminates his employment for “good reason” (as defined below) within two years following a change in control. Payments under the agreements shall be paid or provided (or commence to be paid or provided) within five (5) business days after the executive has satisfied the requirement that executive sign an irrevocable release of all claims against S&T, subject to a six-month delay for compliance with Section 409A, if necessary. (See “Tax Considerations” above). The CEO and NEOs who receive either 200% or 300% of their salary and target annual bonus in a change in control will also be subject to twelve (12) month non-competition and non-solicitation covenants. Each agreement provides that if the executive’s employment is terminated without cause, or terminates for good reason, within the three or two years of a change in control, as applicable for that particular executive, he will also receive payments equal to the amount of money required to maintain health benefits under COBRA. These additional benefits will continue for three years for the President and CEO and for two years for the other NEOs. Each agreement provides that, in the event any benefit received by a NEO in connection with a change in control or in connection with the termination of the NEO’s employment (whether pursuant to the agreement or any other plan, arrangement or agreement) (collectively, the “Total Benefits”) would be subject to the excise tax imposed under Section 4999 of the Code (the golden parachute excise tax), then the Total Benefits will be reduced to the extent necessary so that no portion of the Total Benefits is subject to such excise tax. The definition of “change in control,” as used in the change in control agreements, is fully described on page 28 of this Proxy Statement under the section “Change in Control.” In addition, unvested nonstatutory stock options would immediately vest and become exercisable, under the 2014 Plan.

The following table provides the payments that each NEO would have received under his change in control agreement in the event of a without cause or good reason termination (as described above) upon a change in control of S&T at December 31, 2016:



Name	Multiple of Salary	Lump Sum Payment		Payment in Lieu of Medical Coverage⁽¹⁾		Total Value of Payments
Todd Brice	3X		$2,684,000		$44,352		$2,728,352
Mark Kochvar	2X	949,750		17,760		967,510
David Antolik	2X	1,046,900		9,864		1,056,764
David Ruddock	2X	894,650		29,568		924,218
Ernest Draganza	2X	874,930		29,568		904,498

⁽¹⁾ The amount of money required to maintain health benefits under COBRA for two or three years, as applicable and in accordance with the terms of the executive’s change in control/severance agreement.

Death. Upon the death of an NEO, except for what is described above for termination due to retirement, there are no payments above the life and accidental death and dismemberment insurance proceeds through the S&T Bank Welfare Benefit Plan.

RELATED PERSON TRANSACTIONS

Transactions with Related Parties

S&T Bank has made, and expects to make in the future, extensions of credit in the ordinary course of business to certain directors and officers. These loans are made on substantially the same terms, including interest rates, collateral and repayment terms, as those prevailing at the same time for comparable loans with persons not related to S&T Bank. Such loans do not involve more than normal risk of collectability or present unfavorable features.

On January 31, 1992, S&T Bank entered into a limited partnership arrangement with RCL Partners, Inc. for the construction of 30 apartments in Indiana, Pennsylvania targeted for senior citizens. The total investment by S&T Bank in 1992 was $1,761,766 and entitled S&T Bank to certain tax credits, tax depreciation benefits and a share of cash flows under the Code Section 42 program. Messrs. Delaney (and affiliated parties) and Gatti (and affiliated parties), members of the S&T Board, each hold a one-third interest in RCL Partners, Inc.

During 2016, S&T Bank made payments of $352,425 to a company owned by Mr. Thomas A. Brice for the purchase of furniture and other furnishings for branch and loan production offices and operational centers. Mr. Thomas A. Brice’s son, Todd D. Brice, is a director and is employed by S&T and S&T Bank as President and Chief Executive Officer.

During 2016, S&T Bank made payments aggregating $172,086 to related interests of Ms. Toretti, a member of the S&T Board, for the lease of operations, branch and administrative facilities ($155,706) and the sublease of parking spaces ($16,380) under the arrangements described below. Neither Ms. Toretti nor a family member received these payments. On October 1, 1986, S&T Bank entered into an agreement to lease, from Ms. Toretti and Michael Toretti as trustees under an irrevocable trust, a building and land used as S&T Bank’s North Fourth Street branch and operations center. The terms of the agreement provided for payment of $10,000 per month for the first five years and options to renew for four five-year terms with rent for each option term to be the rent from the previous term, plus 5%. On October 1, 2006, S&T Bank exercised its fourth renewal option at $12,155 per month. Additionally, in September 2006, S&T Bank exercised an extension agreement beginning October 1, 2011 at $12,763 per month providing for four five-year terms at the same terms and conditions of the original lease. The second renewal option was exercised on October 1, 2016 at $13,401 per month, providing the same terms and conditions as the original lease. On June 27, 2011, written consent was given by the third party landlord to tenant Palladio, LLC to sublet 14 parking spaces to S&T Bank, effective September 16, 2012, for $14,280 per year, increasing $420 per year over the remaining five-year term. S&T prepaid $16,380 for parking spaces through September 15, 2016. Ms. Toretti is the President of, and a minority equity owner, in Palladio. The amounts paid by S&T Bank to Palladio for the sublet parking spaces equal the amounts paid by Palladio to the landlord for such parking spaces under their lease agreement. See also “Compensation Committee Interlocks and Insider Participation” on page 14.

Review, Approval or Ratification of Transactions with Related Parties

The Nominating Committee has a written policy for the review, approval or ratification of related party transactions. In accordance with the Nominating Committee’s Related Party Transaction Policy, a “related party transaction” is any transaction, including, but not limited to, any financial transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships, in which S&T and its affiliates (collectively, the “Company”) was, is or will be a participant and in which any “Related Party” had, has, or will have a direct or indirect material interest. A “Related Party” is defined per the policy as follows:


•	Any person who is, or at any time since the beginning of the Company’s last fiscal year was, a director or executive officer of the Company or a nominee to become a director of the Company;


•	Any person who is known to be the beneficial owner of more than 5% of any class of the Company’s voting securities;

•

Any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law and sister-in-law. In addition to the foregoing, any person (other than a tenant or employee) residing in the home of such director, executive officer, nominee or more than 5% beneficial owner; and


•	Any firm, corporation or other entity in which any of the foregoing persons is employed as an executive officer or is a partner or principal or in a similar position; or in which such person has a 10% or greater beneficial ownership interest.

The S&T Board recognizes that related party transactions can present potential or actual conflicts of interest that may raise questions among shareholders or create the appearance that the Company decisions are based on considerations other than the best interests of the Company and its shareholders. It is the Company’s policy to enter into or ratify a related party transaction only when it is determined that the related party transaction in question is in, or is not inconsistent with, the best interests of the Company and its shareholders. Related party transactions, include but are not limited to, situations where the Company may obtain products or services of a nature, quantity or quality, or other terms comparable to those that could be obtained in arm’s length dealings with unrelated third parties; or that are not readily available from alternative sources; or when S&T Bank provides products or services to a Related Party on an arm’s length basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to employees generally.

On an annual basis, each director and executive officer must submit a Director and Executive Officers’ Questionnaire (the “Questionnaire”) for the purpose of assisting in the administration of this policy. The Questionnaire requests the identification of Related Parties. Any person nominated to stand for election as a director must submit a Questionnaire no later than the date of his or her nomination. Any person who is appointed as a director or an executive officer must submit a Questionnaire prior to such person’s appointment as a director or executive officer, except in the case of an executive officer where due to the circumstances it is not practicable to submit the Questionnaire in advance, in which case the Questionnaire must be submitted as soon as reasonably practicable following the appointment.

Directors and executive officers are expected to notify the CRO of any updates to the list of Related Parties. The CRO disseminates a Related Party master list as appropriate within S&T. The recipients of the master list utilize the information contained therein in connection with their respective business units, departments and areas of responsibility to effectuate this policy.

The S&T Board has determined that the Nominating Committee is best suited to review and approve related party transactions. At each calendar year’s first regularly scheduled Nominating Committee meeting, management recommends related party transactions to be entered into by S&T for that calendar year, including the proposed aggregate value of such transactions if applicable. In addition, the Nominating Committee reviews any previously approved or ratified related party transactions that remain ongoing. Based on all relevant facts and circumstances, taking into consideration S&T’s contractual obligations, the Nominating Committee determines if it is in the best interests of S&T and its shareholders to approve or disapprove such proposed transactions or to continue, modify or terminate ongoing related party transactions. At each subsequently scheduled meeting, management updates the Committee as to any material change regarding approved related party transactions.

In the event management recommends any further related party transactions subsequent to the first calendar year meeting, such transactions may be presented to the Nominating Committee for approval or preliminarily entered into by management subject to consultation with the Nominating Committee Chairperson, and ratification by the Nominating Committee at the next scheduled meeting; provided that if ratification shall not be forthcoming, management will make all reasonable efforts to cancel or annul such transaction.

The Nominating Committee has reviewed the types of related party transactions described below and determined that each of the following related party transactions will be deemed to be pre-approved by the Nominating Committee:

1.Any compensation paid to executive officers provided S&T’s Compensation Committee approved or recommended that the S&T Board approve such compensation.

2.Any compensation paid to a director if the compensation is required to be reported in S&T’s proxy statement under Item 402 of the SEC’s compensation disclosure requirements.

3.Any transaction where the Related Party’s interest arises solely from ownership of Common Stock and all shareholders received the same benefit on a pro rata basis (e.g., dividends).

4.Any transaction with a Related Party involving the rendering of services as a common or contract carrier, or public utility, at rates or charges fixed in conformity with law or governmental authority.

5.Any transaction with a Related Party involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.

All of the transactions described above under “Transactions with Related Parties” and under “Compensation Committee Interlocks and Insider Participation” of page 14 were approved by the Nominating Committee in accordance with the Nominating Committee’s Related Party Transaction Policy.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee oversees S&T’s financial reporting process on behalf of the S&T Board of Directors. Management has the primary responsibility for the financial statements, for maintaining effective internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements and related schedules in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of the disclosures in the financial statements. The Audit Committee also reviewed and discussed together with management and the independent registered public accounting firm (Independent Auditors) the results of management’s assessment of the effectiveness of S&T’s internal control over financial reporting and the Independent Auditor’s audit of internal control over financial reporting for the year ended December 31, 2016.

The Audit Committee discussed with S&T’s Internal Auditors and the Independent Auditors the overall scope and plans for their respective audits. The Audit Committee met with the Internal Auditors and Independent Auditors, with and without management present, to discuss the results of their examinations, their evaluations of S&T’s internal controls, including internal controls over financial reporting, and the overall quality of S&T’s financial reporting.

The Audit Committee reviewed and discussed with the Independent Auditors, who is responsible for expressing an opinion on the conformity of those consolidated audited financial statements and related schedules with US generally accepted accounting principles, their judgment as to the quality, not just the acceptability, of S&T’s accounting principles and such other matters as are required to be discussed with the Audit Committee by the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), including PCAOB Auditing Standard No. 16, Communication with Audit Committees, the rules of the Securities and Exchange Commission, and other applicable regulations. In addition, the Audit Committee reviewed and discussed with the Independent Auditors the firm’s independence from S&T’s management and S&T, including the written disclosures received from the firm as required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, and considered the compatibility of non-audit services with the Independent Auditor’s independence.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the S&T Board of Directors, and the S&T Board has approved, that the audited consolidated financial statements and related schedules and management’s assessment of the effectiveness of S&T’s internal control over financial reporting be included in the Annual Report on Form 10-K for the year ended December 31, 2016, for filing with the SEC.

Submitted by the Audit Committee of the S&T Bancorp, Inc. Board of Directors:

Frank Palermo (Chairman); Jeffrey Grube, Frank Jones and Charles Urtin.

In accordance with and to the extent permitted by applicable law or regulation, the information contained in the Report of the Audit Committee and the Audit Committee Charter shall not be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Exchange Act, and shall not be deemed to be soliciting material or to be filed with the SEC under the Exchange Act.
