BARTHELEMY NICOLAS 4

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.
