Item 8.01 Other Events.

The Company is finalizing the review of its previously announced restatement (the “Restatement”) with respect to its previously-issued unaudited interim condensed consolidated financial statements for the fiscal third quarter ended December 31, 2024 contained in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on February 12, 2025 (the “Non-Reliance Period”), which the Company previously announced in its Current Report on Form 8-K filed with the SEC on August 8, 2025 (the “Prior Form 8-K”). Subject to the completion of such review, the Company currently expects that the Restatement will result in a decrease of approximately $3.9 million in revenue and a similar decrease in net loss from operations in the Non-Reliance Period, which is consistent with the Company’s disclosure in the Prior Form 8-K.
