Repligen (RGEN) Director Nicolas Barthelemy Receives RSU Award

What Happened

Nicolas Barthelemy, a member of Repligen Corporation's Board of Directors, received awards reported as acquisitions on May 14, 2026: 995 restricted stock units (RSUs) and 2,239 derivative units, all reported at $0.00 per share (no cash paid). Total units granted: 3,234. These are compensation awards, not open-market purchases or sales.

Key Details

Transaction date and price: 2026-05-14, acquired at $0.00 per unit (codes: A = award/grant; one grant reported as derivative).
Vesting: Awards vest on the earlier of May 14, 2027, one year from grant, or the date of the next annual meeting of shareholders.
Deferral: Mr. Barthelemy elected to defer settlement of the 995 RSUs under Repligen’s Deferred Compensation Plan for Non-Employee Directors; vested units will be issued in accordance with his deferral election following separation from service. Awards may be settled only in shares.
Shares owned after transaction: Not disclosed in this filing.
Filing timeliness: Report filed 2026-05-18 for a 2026-05-14 transaction; appears to be timely under Form 4 reporting rules.

Context

These awards are standard director compensation (RSUs/derivative units) and typically reflect pay, not an immediate market view by the director. Because settlement is in stock (and some units are deferred), this does not represent an open-market buy or sale.

Footnotes (2)

[F1]Mr. Barthelemy 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.
[F2]Award vests in full on the earlier of May 14, 2027, one year from grant date, or on the date of the next annual meeting of the Company's shareholders, which has not yet been determined.
