Immaterial Correction of Interim Condensed Consolidated Financial Statements

In connection with our year-end close process, we determined that we had incorrectly excluded from our previously-issued 2025 unaudited condensed consolidated balance sheets: certain prepaid insurance premiums, and a corresponding financing obligation for such insurance premiums. In addition, we determined that we had incorrectly presented the effects of this financing transaction in our previously-issued 2025 unaudited condensed consolidated statements of cash flows. Therefore, our previously-issued interim unaudited condensed consolidated balance sheets and unaudited condensed consolidated statements of cash flows for the first three quarters of 2025 did not reflect these adjustments. These adjustments did not have an impact on our previously-issued 2025 condensed consolidated statements of operations, our previously-issued 2025 condensed consolidated statements of changes in stockholders’ equity, or our cash balances for the interim periods in 2025. We have properly accounted for this matter in our 2025 annual consolidated financial statements included in this Form 10-K.

Management evaluated the materiality of the above items based on an analysis of quantitative and qualitative factors and concluded they were not material to the interim periods of 2025, individually or in aggregate. We intend to prospectively correct our 2025 unaudited condensed consolidated statements of cash flows for the interim periods of 2025 when we file our interim financial statements for 2026.

Trading Arrangements

During the quarter ended December 31, 2025, none of our directors or officers adopted orterminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as those terms are defined in Item 408 of Regulation S-K.
