SIGNET JEWELERS LTD

Management’s evaluation of disclosure controls and procedures

Signet’s disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by Signet in the reports that it files or submits under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The procedures are also designed to ensure that information is accumulated and communicated to management, including the Chief Executive Officer (principal executive officer) and Chief Operating and Financial Officer (principal financial officer), as appropriate to allow timely decisions to be made regarding required disclosure. Internal controls over financial reporting, no matter how well designed, have inherent limitations, including the possibility of human error and the override of controls. Therefore, even those systems determined to be effective can provide only “reasonable assurance” with respect to the reliability of financial reporting and financial statement preparation and presentation.

Management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures in accordance with Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on such evaluation, the principal executive officer and principal financial officer have concluded that such disclosure controls and procedures were effective as of January 31, 2026.

Management’s annual report on internal control over financial reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with GAAP.

Management conducted an evaluation of internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management determined that the Company’s internal control over financial reporting was effective to accomplish their objectives at the reasonable assurance level as of January 31, 2026.

The Company’s independent registered public accounting firm, KPMG LLP, audited the Fiscal 2026 consolidated financial statements of Signet and has also audited the effectiveness of internal control over financial reporting as of January 31, 2026. Unqualified opinions have been issued thereon, the details of which are included within Item 8 of this Annual Report on Form 10-K.

Changes in internal control over financial reporting

There were no changes in internal control over financial reporting during the quarter ended January 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
