TABLE OF CONTENTS Audit-Related Matters

Audit Committee Report The Audit Committee has prepared the following report for the Company’s shareholders. The Audit Committee of the Company, whose chair is Ms. Jordan and whose other members are Ms. Bertone and Messrs. Harlan and Sparks, met four times during 2024. The Audit Committee of the Company is composed of independent, non-employee directors and operates under a written charter adopted by the Board of Directors. The Audit Committee has met and held discussions with the Company’s management and its independent registered public accounting firm and meets periodically with both the Company’s internal auditors and its independent registered public accounting firm without management present. Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with GAAP, and the Audit Committee has reviewed and discussed the audited consolidated financial statements with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board, or PCAOB, and the SEC. The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communication with the Audit Committee concerning independence. The Audit Committee discussed with the independent registered public accounting firm the firm’s independence and considered the compatibility of non-audit services with the auditor’s independence. Based on the Audit Committee’s review and discussions referred to above, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC and the securities commissions or similar regulatory authorities in Canada on February 13, 2025. This report is submitted on behalf of the Audit Committee.
