Summary

• Mitchell P. Kopin, Daniel B. Asher, and Intracoastal Capital LLC (collectively, the "Reporting Persons") have filed an Amendment No. 1 to Schedule 13G for SeaStar Medical Holding Corporation.
• As of September 30, 2025, the Reporting Persons beneficially owned an aggregate of 3,098,175 shares of SeaStar Medical Holding Corporation's common stock.
