        <footnote id="F1">The original Form 4, filed on April 3, 2024, is being amended by this Form 4 amendment solely to correct an administrative error, which misreported that 120,981 restricted stock units (&quot;RSUs&quot;) were granted on April 1, 2024, when in fact, 124,779 RSUs were granted. As a result of this update, the number of shares beneficially owned by the reporting person following such transaction has been correspondingly increased by 3,798 shares. As previously disclosed, each RSU was granted on April 1, 2024, under the Certara, Inc. 2020 Incentive Plan and represents a right to receive one share of common stock or the cash equivalent.  The RSUs will vest and settle in three equal installments on April 1, 2025, April 1, 2026, and April 1, 2027.</footnote>
