Certara (CERT) President Robert Aspbury Receives Awards; Shares Withheld

What Happened

  • Robert Aspbury, President, Predictive Tech at Certara, had equity awards vest and convert into common stock on April 1, 2026. The filing reports 14,510 shares granted/awarded (PSUs/RSUs) and three derivative conversions totaling 33,167 shares (7,852 + 10,127 + 15,188), for a gross of 47,677 shares acquired at $0.00 (award/settlement).
  • To satisfy tax withholding obligations, 22,411 shares were withheld/disposed at $5.70 per share, generating approximately $127,743 in cash to cover taxes (individual withholding lots: 6,821; 3,691; 4,760; 7,139). Some converted derivative entries are shown as disposed in the filing (consistent with net settlement/tax withholding).

Key Details

  • Transaction date: April 1, 2026; Form 4 filed April 3, 2026 (appears timely).
  • Price(s): Awarded/converted shares reported at $0.00; tax-withheld shares at $5.70/share.
  • Shares acquired (gross): 47,677 (14,510 awards + 33,167 conversions). Shares withheld/sold for taxes: 22,411 (cash value ≈ $127,743).
  • Shares owned after transaction: Not specified in the excerpt provided.
  • Footnotes: PSUs granted 4/1/2023 vested and settled 4/1/2026; multiple RSU grants (2023, 2024, 2025) also vested/settled per schedules. Withholding transactions are exempt under Rule 16b-3.
  • Transaction codes: A = Award/Grant, M = Exercise/Conversion of derivative, F = Payment of exercise price or tax liability (withholding).

Context

  • This filing reflects routine vesting/settlement of PSUs/RSUs and related tax withholding—not an open-market purchase or a discretionary sale. The conversion/exercise entries combined with withheld shares indicate a net/cashless-style settlement to cover taxes rather than a market sell-off initiated for investment reasons.
  • For retail investors, such award vesting is a standard compensation event and does not by itself signal insider buying or selling intent.
