SOMNIGROUP INTERNATIONAL INC.

An evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Report. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of June 30, 2026, and were designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting:

We completed the Mattress Firm Acquisition on February 5, 2025. We are currently evaluating the design and controls assessment of Mattress Firm's internal control over financial reporting to incorporate into our financial reporting processes, which will be included in our assessment of internal control over financial reporting for the year ended December 31, 2026.

During the second quarter of 2026, the Company implemented a new enterprise resource planning ("ERP") system to replace the operational and financial systems for its Tempur U.S. production and distribution subsidiaries. The Company completed significant pre-implementation testing and post-implementation testing and monitoring to ensure the effectiveness of internal controls over financial reporting. As a result of this implementation, the Company modified certain existing internal controls over financial reporting and implemented new controls and procedures related to the new ERP system.

There were no other changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that was conducted during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
