Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of March 31, 2026, to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act 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. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of March 31, 2026, our disclosure controls and procedures were not effective. Management identified this based on the timeliness and consistency of execution of oversight and governance impacting the performance of certain internal control activities, which affected the Company’s ability to consistently achieve its control objectives. During the year ended December 31, 2025, the Company continued to develop and refine its disclosure controls and other procedures designed to ensure that information required to be disclosed in reports filed with the SEC is recorded, processed, summarized, and reported within the time periods specified by SEC rules and forms. In response to the identified ineffectiveness of controls, management has worked on enhancing oversight and governance processes, improving documentation of accounting policies and procedures, and engaged experienced third-party advisors to support GAAP compliance and financial reporting. While progress was made during the year ended December 31, 2025 and has continued through the three months ended March 31, 2026, remediation of the material weakness will not be considered complete until the redesigned controls have operated effectively for a sustained period and have been validated through testing.
