EGLINTON MANNER CARRIE 4

What Happened

• Carrie Eglinton Manner, a director of Repligen Corporation (RGEN), was granted equity awards on 2026-05-14: 995 restricted stock units (RSUs) and 2,239 derivative contingent share awards. Both entries were recorded at $0.00 (no cash paid at grant). Combined, the awards potentially convert into 3,234 shares of common stock.
• These awards are grants (not purchases or sales), typically a form of director compensation rather than a market-directional trade.

Key Details

• Transaction date: May 14, 2026; Form 4 filed May 18, 2026 (timely within the two-business-day reporting window).
• Grant price: $0.00 per share (awarded, not purchased); total cash consideration reported = $0.
• Total potential shares from the grants: 3,234 (995 + 2,239).
• Vesting: Awards vest in full on the earlier of May 14, 2027 (one year from grant) or the date of the next annual meeting of shareholders (not yet determined). The RSUs may be settled only by delivering shares.
• Shares owned after the transaction were not specified in the filing.
• Footnotes: The 995 RSUs represent contingent rights to receive one share each; both awards vest per the schedule above and are reported as equity grants per SEC guidance.

Context

• These are compensation awards to a director and do not involve a market purchase or sale; such awards are common and do not necessarily indicate the director’s private view of the company’s near-term prospects.
• Because settlement is in shares (not cash) and vesting is time- or event-based, these are not option exercises or immediate share sales.
