#### Audit Committee Report
The Audit Committee oversees the financial reporting process on behalf of the Board. The 2024 Audit Committee consisted of directors Bourland, Coffin, Payton, and Opperman (ex-officio).*

The Audit Committee is responsible for pre-approving all auditing services and permitted non-audit services by our independent auditors, or any other auditing or accounting firm, if those fees are reasonably expected to exceed 5.0% of the current year agreed upon fee for independent audit services. The Audit Committee has established general guidelines for the permissible scope and nature of any permitted non-audit services in connection with its annual review of the audit plan and reviews the guidelines with the Board.

Management has the primary responsibility for the consolidated financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited consolidated financial statements in the Annual Report with management including a discussion of the acceptability of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the consolidated financial statements. The Audit Committee also reviewed with management and the independent auditors, management’s assertion on the design and effectiveness of our internal control over financial reporting as of December 31, 2024.

The Audit Committee reviewed with our independent auditors, who are responsible for expressing an opinion on the conformity of those audited consolidated financial statements with accounting principles generally accepted in the United States of America, their judgments as to the acceptability of our 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 those described in Auditing Standard No. 1301, “Communications with Audit Committees”, as may be modified or supplemented. In addition, the Audit Committee has received the written disclosures and the letter from the independent auditors required by PCAOB Rule 3526, “Communication with Audit Committees Concerning Independence”, as may be modified or supplemented, and has discussed this issue with the independent auditors.

The Audit Committee discussed with our internal and independent auditors the overall scope and plans for their respective audits. The Audit Committee meets with the internal and external independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls, and the
