Pay vs Performance Disclosure, Table

PAY VERSUS PERFORMANCE

In accordance with Item 402(v) of Regulation S-K, the Company is required to disclose pay versus performance by comparing compensation amounts previously reported for the last four calendar years to the SEC’s definition of “Compensation Actually Paid” for such years. Also as required by the SEC, this section compares Compensation Actually Paid to various measures used to gauge performance at SIGA. Compensation Actually Paid is a required disclosure item, the amount of which is calculated in accordance with SEC rules. Such measure was not incorporated into the philosophy and strategy of compensation-setting set forth in the “Compensation Discussion and Analysis” of this proxy statement.

(1)	Amount included here is the amount in the “Total” column from the Summary Compensation Table (“SCT”) for the principal executive officer (“PEO”) for the applicable year. For each covered year (i.e. 2020-2023), our PEO was Dr. Gomez.

(2)	“Compensation Actually Paid” is calculated by starting with the amounts reported for the PEO in the “Total” column of the SCT for the applicable year, with such amounts adjusted for stock based compensation. The PEO received no stock based compensation during the years presented.

(3)

Amount included here is the average of the amounts in the “Total” column from the SCT for the applicable year for each of the other non-PEO NEOs. For 2023, our non-PEO NEOs were: Messrs. Luckshire, Hruby and Varma. For 2022, 2021 and 2020, our non-PEO NEOs were Messrs. Luckshire and Hruby and Ms. Robin E. Abrams (former General Counsel and Chief Administrative Officer). The 2022 amount was impacted by the resignation of Ms. Abrams, effective April 18, 2022. The 2023 amount includes compensation paid to Dr. Varma, pro-rated based on his commencement date with the Company.

(4)	In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Average Total Compensation for the NEOs as a group for each year to determine the compensations “actually paid”.

Operating income (pre-tax) is a financial measure that is consistent with U.S. GAAP that is considered by the Company as part of its executive compensation program. The Compensation Committee reviews a variety of performance goals and metrics for the purpose of awarding compensation to executive officers that are consistent with the Company’s overall compensation philosophy and the long-term interests of its shareholders. Among these, the Compensation Committee has identified operating income (pre-tax) as the most important financial performance measure (that is not otherwise required to be disclosed in the table above) used by the Company to link compensation actually paid to its NEOs for the year ended December 31, 2023 to the Company’s performance.
