Aspbury Robert 4

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).

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.
