WALSH MATTHEW M 4

What Happened

• Matthew M. Walsh, a director of Certara, converted 15,757 restricted stock units (RSUs) into common shares and was also granted 33,222 new RSUs on May 14, 2026. The reported price for these transactions is $0.00 because these were RSU conversions/grants (compensation), not cash purchases or open-market sales. The filing shows an "M" code (exercise/conversion of a derivative) for the conversion and an "A" code (award/grant) for the new RSU award.

Key Details

• Transaction date: May 14, 2026; Filing date: May 15, 2026 (filed timely).
• Converted (M): 15,757 shares at $0.00 (reported both as acquired common stock and as disposition of the derivative instrument to reflect conversion).
• Awarded (A): 33,222 RSUs at $0.00 (each RSU converts to one share upon vesting).
• Shares owned after the transaction: not specified in the filing.
• Footnotes:
  • F1: The 15,757 RSUs were originally granted May 21, 2025 and vested/converted to common stock on May 14, 2026 (issuer’s annual meeting).
  • F2: The 33,222 RSUs were granted May 14, 2026 and vest on the earlier of one year from grant or the issuer’s next annual meeting.
• No 10b5-1 plan, tax-withholding sale, or cash proceeds are indicated in the filing.

Context

• These transactions are compensation-related (RSU vesting and a new RSU award). The conversion of RSUs to shares is not a market purchase; the grant is a future entitlement to shares if and when the RSUs vest. Such compensation filings reflect equity awards and do not necessarily indicate insider buying or selling sentiment.
