SharkNinja, Inc.

Evaluation of Controls and Procedures

Under the supervision, and with the participation of, our management, including our Chief Executive Officer and Chief Financial Officer, we performed an evaluation 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 September 30, 2026.

Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of September 30, 2026 to provide reasonable assurance that the information we are required to disclose in the reports we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management to allow timely decisions regarding required disclosures due to the material weaknesses in internal control over financial reporting which, as previously disclosed in Part II, Item 9A. “Controls and Procedures” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, existed as of December 31, 2025 and continued to exist as of September 30, 2026.

Remediation Plan for Material Weaknesses

With the oversight of the Audit Committee of our Board of Directors, we have continued throughout fiscal year 2026 to take steps to remediate the material weaknesses previously disclosed in Part II, Item 9A, “Controls and Procedures,” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 by implementing changes to our internal control over financial reporting and will continue these remediation efforts throughout 2026. Our remediation efforts include the following completed and ongoing actions:

•Re-designing and implementing IT general controls related to financial accounting and reporting systems, including implementing robust monitoring controls as appropriate.

•Completed the development and implementation of a standard internal controls framework for System Development Life Cycle in the third quarter of 2026 for use across all IT applications.

•Designing and implementing additional control activities and evaluating the operating effectiveness of control activities that operate at a level of precision to identify all potentially material errors.

•Enhancing training awareness programs to address IT general controls and business process controls that emphasize policies for the retention of sufficient evidence of the performance of control activities.

•Developing and enhancing policies for current employees, new hires, and external consultants to ensure they are held accountable for design, implementation, and execution of our internal controls over financial reporting.

•Investing in the development of internal capabilities by insourcing the Internal Audit function to perform SOX testing to promote continuity, embed institutional knowledge of the business, and enable more proactive identification of operational and control improvement opportunities.

While we believe that the foregoing efforts will effectively remediate the remaining material weaknesses, until these remedial actions have been completed and the required internal controls have been fully implemented and operating for a sufficient period of time to be able to conclude that material weaknesses described above have been successfully remediated, our internal control over financial reporting will remain ineffective.

We cannot provide any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts and there is no assurance as to when such remediation will be completed. In addition, as we continue to evaluate and work to improve internal control over financial reporting, management may determine to take additional measures to address control deficiencies or determine to modify the remediation plan described above.

Changes in internal control over financial reporting

Other than the remediation efforts described above, there have been no changes during the three months ended September 30, 2026, in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
