OCEANFIRST FINANCIAL CORP 10-K

Item 9A. Controls and Procedures (a) Disclosure Controls and Procedures The Company’s management, including the Company’s principal executive officer and principal financial officer, have evaluated the effectiveness of the Company’s “disclosure controls and procedures” as such term is defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Exchange Act, as amended. Based upon their evaluation, the principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective. Disclosure controls and procedures are the controls and other procedures that are designed to ensure that the information required to be disclosed in the reports that the Company files or submits under the Exchange Act with the SEC (1) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (2) is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. (b) Management Report on Internal Control Over Financial Reporting Management of OceanFirst Financial Corp. and its subsidiaries are responsible for establishing and maintaining effective internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's Board, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP 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. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management, under the supervision and with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, and oversight of the Board, evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025 using the criteria set forth by the Committee of Sponsoring Organizations of the COSO 2013 Framework. Based on this assessment, management determined that, as of December 31, 2025, the Company’s internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The Company’s independent registered public accounting firm has issued an audit report on the effectiveness of the Company’s internal control over financial reporting. This report appears on page 74. (c) Changes in Internal Control Over Financial Reporting There were no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
