SeaStar Medical Holding Corp 8-K/A

What Happened

• SeaStar Medical Holding Corporation (Nasdaq: ICU; warrants: ICUCW) filed an 8-K on December 23, 2025 announcing that the effective date of a previously stockholder-approved reverse stock split will be 12:01 AM Eastern Time on January 5, 2026. The Form 8-K lists the earliest event date as December 18, 2025 and includes a press release (Exhibit 99.1).

Key Details

• Filing date of Form 8-K: December 23, 2025 (earliest event reported: December 18, 2025).
• Effective date and time of reverse split: 12:01 AM on January 5, 2026.
• The reverse split was previously approved by stockholders; the 8-K announces only the effective date (no split ratio is disclosed in this filing).
• Exhibit included: Press release dated December 23, 2025 (Exhibit 99.1).

Why It Matters

• A reverse stock split consolidates outstanding shares into fewer shares and typically increases the per‑share price on a proportional basis. For investors, this can affect share count, per-share metrics, and trading liquidity.
• Because the 8-K does not state the split ratio, shareholders should review the company’s prior disclosures and the press release (Exhibit 99.1) for the specific ratio and any additional implementation details before the effective date.
