FIRST COMMONWEALTH FINANCIAL CORP PA

Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms of the Securities and Exchange Commission.

In addition, our management, including our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal controls over financial reporting to determine whether any changes occurred during the fourth fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. No such changes were identified in connection with this evaluation.

Ernst & Young LLP, Pittsburgh, Pennsylvania, (U.S. PCAOB Auditor Firm I.D.:42), the independent registered public accounting firm that audited our consolidated financial statements included in this Annual Report on Form 10-K, has issued an audit report on the effectiveness of our internal control over financial reporting as of December 31, 2023. The report, which expresses an unqualified opinion on the effectiveness of our internal control over financial reporting as of December 31, 2023, is included at the end of Item 8 under the heading Report of "Independent Registered Public Accounting Firm.”

MANAGEMENT’S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING

First Commonwealth is responsible for the preparation, the integrity, and the fair presentation of the Consolidated Financial Statements included in this annual report. The Consolidated Financial Statements and notes to the financial statements have been prepared in conformity with generally accepted accounting principles and include some amounts based upon management’s best estimates and judgments.

First Commonwealth’s management is responsible for establishing and maintaining effective internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f), that is designed to produce reliable financial statements in conformity with generally accepted accounting principles and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. Under the supervision and with the participation of management, including First Commonwealth’s principal executive officer and principal financial officer, First Commonwealth conducted an evaluation of the effectiveness of internal control over financial reporting based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

All internal control systems, no matter how well designed, have inherent limitations, including the possibility that a control can be circumvented and that misstatements due to error or fraud may occur without detection. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Based on First Commonwealth’s evaluation based on criteria established in Internal Control-Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), management concluded that internal control over financial reporting was effective as of December 31, 2023. The effectiveness of First Commonwealth’s internal control over financial reporting as of December 31, 2023 has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in their audit report which is included herein.
