Explanatory Note
On September 16, 2025, Strata Critical Medical, Inc. (the “Company”), filed with the U.S. Securities and Exchange Commission a Current Report on Form 8-K (the “Initial Report”) to announce the completion of the acquisition of Keystone Perfusion Services, LLC ("Keystone") by way of acquiring all the issued and outstanding equity interests of Keystone.

This Amendment No. 1 (this “Amendment”) to the Initial Report is being filed to include the historical financial statements of Keystone Perfusion Services P.C. required by Item 9.01(a), and the unaudited pro forma condensed consolidated financial information required by Article 11 of Regulation S-X in connection with the sale of the Company’s Passenger business to Joby Aero, Inc. and the acquisition of Keystone (collectively, the “Transactions”) that were previously omitted from the Initial Report as permitted by Item 9.01(a). No other changes have been made to the Initial Report.

The pro forma financial information included in this Amendment has been presented for informational purposes only and is not necessarily indicative of the consolidated financial position or results of operations that would have been realized had the Transactions occurred as of the dates indicated, nor is it meant to be indicative of any anticipated financial position or future results of operations that the Company will experience after the Transaction. Except as set forth herein, no modifications have been made to information in the Initial Report, and the Company has not updated any information contained therein to reflect events that have occurred since the date of the Initial Report.
