May 14, 2026 · Form 4 insider transaction
MUIR GLENN P bought 995 shares of Repligen Corporation at $0.00 per share, a transaction worth N/A. The trade was recorded as grant or award and disclosed on an SEC Form 4, filed 4 days after the transaction.
Mr. Muir was awarded 995 restricted stock units. Each restricted stock unit represents a contingent right to receive one share of Repligen Corporation's Common Stock. The restricted stock units vest on the earlier of May 14, 2027, one year from the grant date, or the date of the next annual meeting of the Company's shareholders, which has not yet been determined. The Reporting Person has elected to defer settlement of these restricted stock units pursuant to the Repligen Corporation Deferred Compensation Plan for Non-Employee Directors. Once vested, the shares will be issued in accordance with the Reporting Person's deferral election following the separation of the Reporting Person's service as a Director. The restricted stock units may be settled only by delivering shares of Repligen Corporation's Common Stock, and thus, the grant is being reported in Table 1 as allowed per SEC guidance.
