KURIYEL RALF 4

What Happened

• Ralf Kuriyel, Senior Vice President, R&D at Repligen (RGEN), had shares withheld to satisfy tax withholding obligations tied to the release of restricted stock units (RSUs). Two withholding transactions occurred: 444 shares at $128.73 on 2026-02-27 ($57,156) and 923 shares at $124.97 on 2026-03-02 ($115,347), for a combined 1,367 shares and approximately $172,503 in value. This is an administrative tax-withholding event (not an open-market sale).
