Explanation of Responses:

Id Content
F1 On April 18, 2025, the Issuer's Board of Directors approved an amendment of the outstanding performance stock units ("PSUs") previously granted to the reporting person on March 25, 2024, to account for the Issuer's payment of a special cash dividend of $0.60 per share in April 2024 that would have applied to such PSUs based on the reporting person's actual period of service with the Issuer. As modified, the relevant stock price hurdles for these PSUs were each lowered by $0.60 such that (a) 6,920 PSUs vested immediately, (b) 6,920 PSUs vest if, during any period of 90 consecutive trading days during the three-year period beginning on the grant date (the "Performance Period"), the Issuer's Common Stock closing stock price (plus the per share value of any dividends declared during the measurement date) (the "Stock Price") is at or above $7.40, and (c) 6,921 PSUs vest, if during any 90 consecutive trading days during the Performance Period, the Stock Price is at or above $8.40.
F2 Represents the withholding by SIGA Technologies, Inc. of shares of Common Stock (based on $5.99 per share, the closing stock price on April 17, 2025) to satisfy tax withholding obligations associated with the vesting of PSUs and the consequent issuance of Common Stock.
F3 PSUs represent contingent rights to receive Common Stock on a one-for-one basis.
