FAQ

What ownership stake in SeaStar Medical (ICU) is reported in this Schedule 13G/A?

The reporting investors disclose beneficial ownership of 3,980,665 SeaStar Medical shares, or 9.99% of the common stock. This stake is calculated using 35,865,834 shares outstanding plus certain warrant shares included in the ownership calculation.

Who are the reporting persons in the SeaStar Medical (ICU) Schedule 13G/A?

The filing is made jointly by Mitchell P. Kopin, Daniel B. Asher and Intracoastal Capital LLC. Kopin and Asher are U.S. individuals, while Intracoastal is a Delaware limited liability company holding the warrants that provide the reported beneficial ownership.

How do the reporting holders of ICU reach 3,980,665 beneficially owned shares?

The 3,980,665 ICU shares come from three Intracoastal warrants exercisable into 1,346,154, 1,346,154 and 1,240,136 shares. These warrant shares are included in the ownership calculation, subject to blocker provisions that cap total beneficial ownership at specified percentages.

What ownership blockers apply to the SeaStar Medical (ICU) warrants?

Certain Intracoastal warrants cannot be exercised above 9.99% or 4.99% beneficial ownership thresholds. These blocker provisions limit how many shares may be acquired at any time, keeping reported ownership at 9.99% despite additional warrant capacity.

How many ICU shares would be beneficially owned without the warrant blockers?

Without the blocker provisions, the reporting persons would beneficially own 5,342,845 SeaStar Medical shares. This larger number reflects all six Intracoastal warrants, including those currently excluded due to the 9.99% and 4.99% ownership caps.

Are the ICU holdings reported in this Schedule 13G/A intended to influence control of SeaStar Medical?

The reporting investors certify the ICU securities are not held to change or influence control of SeaStar Medical. They state the holdings are not connected with any transaction having that purpose, other than activities solely related to a possible nomination under specific proxy rules.
