• Amended Resale Registration

  The company filed an S-1/A to register an aggregate of 2,000,000 shares of common stock for resale by Lincoln Park Capital Fund, LLC. This amends a prior S-1 filing from April 28, 2026, which registered 1.66 million shares, by clarifying the total registered amount.

• Substantial Potential Dilution

  If all 2,000,000 registered shares are issued and sold, it would represent approximately 50.04% dilution to the 3,997,002 shares outstanding as of April 20, 2026.

• Access to Capital

  The company may receive up to an additional $14,657,887.43 in gross proceeds from sales to Lincoln Park under an existing purchase agreement, which was established on April 25, 2025, for a total commitment of $15.0 million.

• Critical for Going Concern

  This capital access is vital for SeaStar Medical, which recently disclosed substantial doubt about its ability to continue as a going concern in its 2025 annual report.

This S-1/A filing clarifies the total number of shares registered for resale by Lincoln Park Capital to 2,000,000, an increase from the 1.66 million shares previously registered. This represents a potential dilution of over 50% to existing shareholders if all shares are issued and sold. While highly dilutive, the ability to access up to an additional $14.66 million from this equity line of credit is critical for SeaStar Medical, especially given the company's recent disclosure of substantial doubt about its ability to continue as a going concern. This financing provides a necessary, albeit costly, pathway to extend the company's operational runway.
