On December 11, 2025, Certara, Inc.

Feehery who is departing from his role as the Company’s Chief Executive Officer and as a member of the Company’s Board of Directors (the “Board”), effective as of the close of business on December 31, 2025. The Company also announced the Board’s appointment of Mr. Resnick to serve as a Class III member of the Board, effective as of the Start Date, with a term expiring at the Company’s 2026 annual meeting of stockholders.
Mr. Resnick, 53, has served as the President for the U.S. and Canada regional business of IQVIA Holdings Inc. (“IQVIA”), a leading global provider of clinical research services, commercial insights and healthcare intelligence to the life sciences and healthcare industries, since July 2019. Prior to his current role, Mr. Resnick served as President of IQVIA’s Real World Solutions business, which he led since the merger of IMS Health and Quintiles in 2016. Jon first joined IMS Health, a predecessor company to IQVIA, in 2002 within the consulting division and subsequently held several different European and U.S. leadership positions within the consulting and services and real-world businesses. Prior to IMS Health, Mr. Resnick worked for the U.S. Senate Committee on Finance, where he advised on healthcare policy and developed legislation around Medicare, Medicaid, and broader health care reform. Mr. Resnick holds an MBA from the Kellogg School of Management, Northwestern University and a BA in Political Science from Union College.
There are no family relationships between Mr. Resnick and any of the directors or executive officers of the Company, and there are no transactions in which Mr. Resnick has a direct or indirect material interest requiring disclosure under Item 404(a) of Regulation S-K. There is no arrangement or understanding between Mr. Resnick and any other person pursuant to which Mr. Resnick was selected as a director or officer of the Company.
Employment Agreement with Mr. Resnick
In connection with Mr. Resnick’s appointment, the Company entered into an employment agreement (the “Employment Agreement”) with Mr. Resnick pursuant to which Mr. Resnick will commence employment effective as of the Start Date. The Employment Agreement provides that Mr. Resnick will receive an initial annual base salary of $750,000 and will be eligible for an annual target bonus opportunity of 100% of his base salary. In addition, the Employment Agreement provides that Mr. Resnick will receive a “make whole” restricted stock unit grant with a target value of $6,500,000 in respect of forfeited equity awards from Mr. Resnick’s prior employer that will vest on the first two yearly anniversaries of the Start Date.

The 2025 and 2026 long-term incentive awards will be comprised of 60% performance-vesting stock units and 40% time-vesting restricted stock units. From 2027 onward, Mr. Resnick will be eligible to receive annual long-term incentive awards consistent with other senior executives of the Company at a grant level that is commensurate with his status as Chief Executive Officer.
In the event of a termination of Mr. Resnick’s employment by the Company without cause or by Mr. Resnick for good reason, Mr. Resnick will be entitled to severance benefits consisting of (i) 1 times the sum of his salary and target bonus (or 1.5 times the sum of his salary and target bonus if the termination is during the six months prior to or the 24 months following a change in control (the “change in control protection period”)), (ii) a pro-rated annual bonus for the year of termination based on actual performance, (iii) company-paid COBRA coverage for up to 12 months (or for up to 18 months if the termination is during the change in control protection period), (iv) full accelerated vesting of any unvested portion of the make-whole equity grant, (v) full vesting of the next scheduled vesting tranche of any then-outstanding time-vesting restricted stock units granted (or full vesting of any then-outstanding time-vesting restricted stock units if the termination is during the change in control protection period) and (vi) prorated vesting of any then-outstanding performance-vesting stock units granted based on actual performance achieved through the date of the termination of Mr. Resnick’s employment (or full vesting of any then-outstanding performance-vesting stock units based on actual performance achieved if the termination is during the change in control protection period).
