In addition to the other information set forth in this Quarterly Report, you should carefully consider the risks discussed in Part I, Item 1A “Risk Factors” in our 2024 Annual Report. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results. Except as set forth below, there have been no material changes in the risk factors discussed in Part I, Item 1A “Risk Factors” in our 2024 Annual Report.

We identified a material weakness in our internal control over financial reporting, and if we are unable to remediate this material weakness, or if we experience additional material weaknesses or other deficiencies in the future or otherwise fail to maintain an effective system of internal control, we may not be able to accurately and timely report our financial results.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements may not be prevented or detected on a timely basis. In connection with the preparation of our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2025, we identified a material weakness related to the preparation and review of the unaudited condensed consolidated statements of cash flows.

Remediation efforts place a significant burden on management and add increased pressure to our financial resources and processes. As a result, we may not be successful in making the improvements necessary to remediate the material weakness identified by management, be able to do so in a timely manner, or be able to identify and remediate additional control deficiencies, including material weaknesses, in the future. Additionally, completion of remediation does not provide assurance that our remediation or other controls will continue to operate properly or remain adequate and we cannot assure you that we will not identify additional material weaknesses in our internal control over financial reporting in the future.

If we are unable to successfully remediate our existing material weakness or any future material weaknesses or other deficiencies in our internal control over financial reporting or disclosure controls and procedures, our ability to record, process and report financial information accurately, and to prepare financial statements within the time periods specified by the rules and forms of the SEC, could be adversely affected. This failure could negatively affect the market price and trading liquidity of our common stock, cause investors to lose confidence in our reported financial information, subject us to civil and criminal investigations and penalties and generally materially and adversely impact our business and financial condition.

We reached a determination to restate certain of our previously issued unaudited condensed consolidated financial statements, which may affect investor confidence.

We previously reached a determination to restate our unaudited consolidated financial statements and related disclosures for the quarters ended March 31, 2025 and June 30, 2025, following the identification of an error in the unaudited condensed consolidated statements of cash flows as a result of the misclassification of certain amounts between cash flows from operating activities and cash flows from financing activities. As a result, we have become subject to a number of additional risks and uncertainties, which may affect investor confidence in the accuracy of our financial disclosures.
