Item 7.01 Regulation FD Disclosure. On August 4, 2026, Certara, Inc. (the “Company”) hosted its second quarter 2026 earnings conference call and posted on its website its second quarter 2026 earnings presentation. On the earnings conference call, there was a misstatement in the spoken reference to the 2025 adjusted EBITDA generated by the Company’s recently divested Regulatory and Medical Writing business, which was quoted as having “generated approximately $17 million of adjusted EBITDA in 2025 excluding unallocated overhead costs” (emphasis added), which should have been quoted as having “generated approximately $17 million of adjusted EBITDA in 2025 including unallocated overhead costs” (emphasis added). The 2025 adjusted EBITDA generated by the Regulatory and Medical Writing business excluding unallocated corporate expense that will remain with the Company is approximately $23 million. The second quarter 2026 earnings presentation contained the same misstatement and an updated version of the presentation has been posted to the Company’s website, available at ir.certara.com under the heading “Financials & Filings—Quarterly Results”. The foregoing clarification has no impact on previously reported financial results, year-over-year comparisons or the Company’s 2026 Financial Outlook.
