Emergent BioSolutions SVP William Hartzel Surrenders Shares After PSU Payout
What Happened
William Hartzel, Senior Vice President, Bioservices at Emergent BioSolutions (EBS), had performance stock units (PSUs) finally certified on Feb 6, 2026. The Compensation Committee certified the 2023–2025 PSUs at a 25% payout, producing an actual award of 1,922 shares. As a result, 5,771 shares (the difference from previously reported target shares) were disposed to the issuer, and 630 shares were withheld to cover taxes. The reported cash-equivalent dispositions: 5,771 shares @ $10.92 = $63,019 and 630 shares @ $10.92 = $6,880 (total ≈ $69,899).

Context
- This was not an open-market sale for liquidity or investment — it reflects PSU settlement mechanics: a reduced PSU payout (25% of target) with excess previously-reported target shares not issued (surrendered) and shares withheld for taxes. Such administrative dispositions are common when performance awards pay out below target or when companies withhold shares for taxes.
