Explanation of Responses:

1. Represents shares withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of restricted stock units.

2. On September 12, 2025, the reporting person filed a Form 4 which reported in column 5 of Table I that, following the withholding of 3,707 shares by the Issuer to satisfy tax withholding obligations in connection with the vesting of restricted stock units, the reporting person directly beneficially owned 100,053 shares. In fact, as reflected in this amendment, the reporting person inadvertently failed to disclose the withholding of 5,483 shares by the Issuer on September 4, 2025 to satisfy tax withholding obligations in connection with the vesting of restricted stock units. As such, the reporting person actually directly beneficially owned 94,570 shares following the withholding of 3,707 shares on September 10, 2025. As a result, the original Form 4 mistakenly overstated the reporting person's direct beneficial ownership by 5,483 shares.

FAQ

What does Amir Cohen’s amended Form 4/A for Strata Critical Medical (SRTA) report?

The amended Form 4/A reports routine share withholdings used to pay taxes on vested restricted stock units. It clarifies that 9,190 shares of Class A common stock were withheld by the issuer and corrects an earlier overstatement of Cohen’s reported direct holdings.

How many Strata Critical Medical (SRTA) shares were withheld for Amir Cohen’s tax obligations?

A total of 9,190 Class A common shares were withheld to cover Amir Cohen’s tax obligations. This includes 5,483 shares withheld on September 4, 2025 and 3,707 shares withheld on September 10, 2025, all in connection with restricted stock unit vesting.

What are Amir Cohen’s direct Strata Critical Medical (SRTA) holdings after the tax withholdings?

After the tax-related withholdings, Amir Cohen directly owns 94,570 shares of Strata Critical Medical Class A common stock. This updated figure reflects both September 2025 withholding events tied to restricted stock unit vesting and corrects the previously overstated ownership number.

Were Amir Cohen’s Strata Critical Medical (SRTA) transactions open-market sales?

No, these transactions were not open-market sales. The issuer withheld shares to satisfy Amir Cohen’s tax liabilities arising from restricted stock unit vesting. Such F-code transactions represent tax-withholding dispositions back to the company rather than discretionary buying or selling in the market.

What error does the amended Form 4/A correct for Strata Critical Medical (SRTA)?

The amendment corrects a prior Form 4 that failed to report the withholding of 5,483 shares on September 4, 2025. Because of that omission, Cohen’s direct beneficial ownership had been overstated; it should have been 94,570 shares after the September 10, 2025 withholding.

Why were Strata Critical Medical (SRTA) restricted stock units linked to share withholdings for Amir Cohen?

The share withholdings occurred because Cohen’s restricted stock units vested, creating taxable income. Instead of paying cash, a portion of the vested shares—9,190 in total—was withheld by the issuer to satisfy tax obligations, which is a common administrative mechanism.
