Tomkiel Melissa M. 4/A

What Happened

• Melissa M. Tomkiel, Co-CEO, General Counsel and a director of Strata Critical Medical, had 29,730 shares of Class A common stock withheld by the issuer to satisfy tax withholding obligations related to the vesting of restricted stock units. The withholding was recorded as a disposition (code F) at an implied value of $5.87 per share, totaling $174,515, on June 8, 2026. This is an amended Form 4 correcting the original filing’s transaction code.

Key Details

• Transaction date: June 8, 2026.
• Shares withheld / disposition: 29,730 shares at $5.87 each; total value $174,515 (code F — tax withholding).
• Amendment: Original Form 4 filed June 10, 2026 inadvertently used sale code "S"; amended on June 18, 2026 to show correct code "F". The Original Form’s footnote correctly described the withholding.
• Footnote: Represents shares withheld by the issuer to satisfy tax withholding on RSU vesting.
• Shares owned after transaction: Not reported in the excerpt provided.

Context

• This was a routine administrative withholding to cover taxes on vested RSUs, not an open-market sale or a purchase. Such withholdings are common and generally not viewed as a signal of insider sentiment about the company’s stock. The amendment corrects reporting detail (transaction code) but does not change the underlying transaction.
