Investing.com -- SeaStar Medical Holding Corporation (NASDAQ:ICU) stock plunged 19.2% on Tuesday after the commercial-stage healthcare company announced plans for a 1-for-10 reverse stock split effective January 5, 2026.
The reverse split is aimed at boosting the company’s share price to regain compliance with Nasdaq’s $1.00 minimum bid price requirement. SeaStar Medical, which focuses on treatments for critically ill patients facing organ failure, will continue trading under its "ICU" ticker symbol but with a new CUSIP number (81256L302).
The company’s stockholders approved the reverse split at a Special Meeting on December 18, 2025. When implemented, every 10 pre-split shares will automatically convert to one share of common stock, with stockholders receiving whole shares in lieu of any fractional shares they would otherwise be entitled to.
The split will proportionally reduce the number of shares issuable upon exercise of outstanding stock options and certain warrants, while causing a corresponding increase in their exercise prices.
SeaStar Medical noted that stockholders owning shares through banks or brokers will have their positions automatically adjusted to reflect the reverse split, subject to their brokers’ particular processes. The company’s transfer agent, Continental Stock Transfer and Trust Company, will provide information to stockholders of record regarding their post-split share ownership.
