The Registrant is unable to timely file its Quarterly Report on Form 10-Q for the period ended June 30, 2024 (the "Form 10-Q") without unreasonable effort and expense because, as previously reported on the Company's Current Report on Form 8-K dated July 10, 2024, the Registrant is in the process of restating its financial statements contained in its Annual Report on Form 10-K for the year ended December 31, 2023 (the "Restatement"), and will be filing an amendment to its Form 10-K (the "10-K/A") including the Restatement, and such Restatement will impact the consolidated balance sheet for the year ended December 31, 2023 contained in the Form 10-Q. The Company is aiming to file the Form 10-K/A in advance of filing the Form 10-Q and intends to file the Form 10-Q as soon as possible thereafter, with the aim of completing all required filings within the five-day extension period provided under Rule 12b-25 of the Securities Exchange Act of 1934, as amended.
