Pedersen Leif E 4

What Happened

• Leif E. Pedersen, President & Chief Commercial Officer of Certara, had a package of performance stock units (PSUs) and restricted stock units (RSUs) vest/settle on April 1, 2026. The filing shows gross issuance/acquisition of 47,677 shares (multiple A and M transaction codes at $0.00). To satisfy tax-withholding obligations, 11,611 shares were withheld/disposed at $5.70 per share, totaling $66,182. Net shares retained from the vesting = 36,066 shares.
• These transactions are equity award settlements and conversions (codes A and M) with accompanying tax-withholding disposals (code F). They reflect routine compensation vesting and tax-related share withholding rather than open-market selling for investment reasons.

Context

• These transactions are best read as compensation vesting and tax-withholding activity (A/M = awards/exercise or conversion; F = shares withheld to pay tax). Withheld shares are not open-market sales by the insider and are routine—generally not interpreted as a signal about insider sentiment.
• For investors watching insider activity, purchases are typically more informative than routine vesting + withholding events.
