Explanatory Note

This Amendment No. 1 to Form 8-K (this "Amendment") amends Form 8-K of SeaStar Medical Holding Corporation (the "Company") that was originally filed with the Securities and Exchange Commission on August 13, 2025, (the "Original Filing"). This Amendment is being filed solely to correct an inadvertent error in the submission of the Original Filing through EDGAR which referenced the incorrect Form 8-K Item Number (Item 2.01) in the EDGAR submission header. This Amendment is being filed through EDGAR to reference the correct Form 8-K Item Numbers (Items 2.02 and 9.01) in the EDGAR submission header. There are no changes to the Original Filing itself (which referenced the correct Item numbers). Except as summarized above, this Amendment continues to speak as of the date of the Original Filing and does not reflect events occurring after the date of the Original Filing or modify or update the disclosures therein in any way.

Item 2.02 Results of Operations and Financial Condition.

The information in this Current Report on Form 8-K, including the information contained in the press release furnished as Exhibit 99.1, is deemed to be “furnished” and not “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is not otherwise subject to the liabilities of that Section, and shall not be deemed incorporated by reference into any filing under the Exchange Act or the Securities Act of 1933, as amended, regardless of any general incorporation language in such filing.
