Chairperson). Given Mr. Palermo intends to retire from the S&T Board effective upon the expiration of his term immediately following the annual meeting, the Board will consider the subject of Audit Committee chairpersonship at the Board’s annual reorganizational meeting following the Annual Meeting. All members meet the independence standards for audit committees established by the SEC and NASDAQ. A written charter approved by the Board governs the Audit Committee and complies with current NASDAQ Rules relating to charters and corporate governance. The Audit Committee reviews the adequacy of this charter annually and recommends any proposed changes to the Board. A copy of the charter is included on S&T’s website www.stbancorp.com, under 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 65. The Board has determined that Frank J. Palermo, Jr., CPA, Chair of the Audit Committee and Peter R. Barsz, CPA each qualify as an “audit committee financial expert” as defined in regulations issued pursuant to the Sarbanes-Oxley Act of 2002. The Audit Committee annually reviews the independent registered public accounting firm’s performance and independence in deciding whether to retain the firm or engage a different independent registered public accounting firm. As part of this review, the Audit Committee considers, among other things, the following:

| • |     | The independent registered public accounting firm’s continued independence and objectivity; |

| • |     | The capacity, depth, financial services knowledge and public company experience of the independent registered public accounting firm; |

| • |     | The quality and candor of the independent registered public accounting firm’s communications with the Audit Committee and Management; |

| • |     | The desired balance of the independent registered public accounting firm’s experience and fresh perspective as a result of mandatory audit partner rotation; |

| • |     | External data on audit quality and performance, including recent Public Company Accounting Oversight Board (PCAOB) reports on the independent registered public accounting firm and its peer reviews; |

| • |     | The quality and efficiency of the audit firm’s audit plans and performance conducting S&T’s audit; |

| • |     | The appropriateness of the independent registered public accounting firm’s fees for audit and non-audit services; |
