Management’s Report on Internal Control over Financial Reporting

Management of Pioneer Bancorp, Inc. is responsible for establishing and maintaining effective internal control over financial reporting.

Management evaluates the effectiveness of internal control over financial reporting and tests for reliability of recorded financial information through a program of ongoing internal audits. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance with respect to financial statement preparation.

The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) 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.

Management assessed the Company’s internal control over financial reporting as of December 31, 2025, as required by Section 404 of the Sarbanes-Oxley Act of 2002, based on the criteria for effective internal control over financial reporting described in the “2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.” Based on this assessment, management concludes that, as of December 31, 2025, the Company’s internal control over financial reporting is effective.

The Report of the Independent Registered Public Accounting Firm that attests to the effectiveness of internal control over financial reporting is included under Item 8 “Financial Statements and Supplementary Data” in Part II of this Form 10-K.
