        <footnote id="F1">Consists of performance stock units granted under the Emergent BioSolutions Inc. Stock Incentive Plan. Each PSU represents a right to receive one share of common stock. The PSUs vest upon achievement with respect to adjusted EBITDA margin calculated on a cumulative basis over the three-year period beginning January 1, 2022 and ending December 31, 2024, as certified by the Compensation Committee following the performance period. On February 12, 2025, the final certification date, the Compensation Committee certified the achievement of the 2022-2024 PSUs at a payout factor of 0.00% of target resulting in the actual award of 0 shares of common stock, which is below the 16,916 shares previously reported on March 1, 2022.</footnote>
