LAURENCIN CATO T 4

What Happened

• Laurencin Cato, a director of Alkermes plc, had equity activity reported for May 20–21, 2026. The filing shows two grants on 2026-05-20 for 11,538 and 5,409 restricted stock units (RSUs) (both $0.00 on grant). On 2026-05-21 the filing reports the exercise/conversion of 6,142 derivative units into common shares and a disposition of 6,142 shares. Separately, 1,475 shares were surrendered/withheld to satisfy tax withholding at $36.95 per share, totaling $54,501.
• These transactions are primarily award/grant conversions and routine tax withholding rather than an open-market purchase. One footnote indicates an award is fully vested under its terms.

Key Details

• Transaction dates: Grants on 2026-05-20; exercise/conversion and disposition on 2026-05-21; tax withholding reported on 2026-05-21.
• Prices/values: Tax withholding rate shown as $36.95/share for 1,475 shares = $54,501. Exercise/conversion and disposition entries list no per-share sale price (N/A) in the filing.
• Shares owned after transaction: not specified in the information provided in this summary.
• Footnotes: F1—each RSU represents a right to one share; F2—vesting schedule: vest in full on the earlier of one-year anniversary or next AGM (≥50 weeks after grant); F3—an award is reported as fully vested per its terms.
• Filing timeliness: Report filed 2026-05-22 for activity through 2026-05-21 (appears timely under the Form 4 two-business-day rule).

Context

• Derivative explanation: The filing shows conversion/exercise of derivative awards (likely RSUs or option conversion) into shares, with shares withheld/surrendered to cover taxes — a common “sell-to-cover” or tax withholding mechanism, which is routine and doesn’t necessarily signal a directional view on the stock.
• For retail investors: purchases by insiders tend to be more informative than routine exercises, and this report mainly documents grants, a conversion, and tax-related withholding rather than a clear open-market buy or sell for investment purposes.
