    Item 3.03 - Material Modification to Rights of Security Holders
     
    On December 18, 2025, SeaStar Medical Holding Corporation (“the Company”) filed a Form 8-K announcing that at a special meeting of the shareholders (the "Special Meeting") the stockholders of the Company approved a 1-for-10 reverse stock split of the Company's common stock (the "Reverse Split") and that the Board of Directors of the Company had previously approved the Reverse Split subject to stockholder approval. The Company originally announced a planned effective date for the Reverse Split to be effective at 12:01 AM January 2, 2026. 
     
    On December 23, 2025, the Board of Directors determined to change the date that the Reverse Stock Split will be effective to 12:01 AM January 5, 2026 (the "Effective Date").
     
    The Company's shares of common stock will begin trading on a split-adjusted basis on The Nasdaq Capital Market on January 5, 2026 under the same symbol "ICU". All stock options and warrants of the Company outstanding immediately prior to the Reverse Split will be proportionally adjusted.
     
    As a result of the Reverse Split, every 10 shares of the Company's issued and outstanding common stock will be automatically combined and converted into one issued and outstanding share of common stock, par value $0.0001 per share. The Company will not issue any fractional shares in connection with the Reverse Split. Instead, the number of shares will be rounded up to the next whole number. The Reverse Split will not modify the rights or preferences of the common stock. Immediately after the Reverse Split becomes effective, there will be approximately 3.8 million shares of common stock issued and outstanding.
     
    The Company has appointed its transfer agent, Continental Stock Transfer and Trust Company, Inc., to act as exchange agent for the reverse stock split. Stockholders owning shares via a bank, broker or other nominee will have their positions automatically adjusted to reflect the Reverse Split and will not be required to take further action in connection with the Reverse Split, subject to brokers' particular processes.
     
    Item 8.01 - Other Events
     
    On December 23, 2025, the Company issued a press release announcing that that the Effective Date of the previously stockholder approved Reverse Split will be 12:01 AM January 5, 2026.
