Hopkinson Craig C. 4

What Happened

• Craig C. Hopkinson, EVP R&D and Chief Medical Officer of Alkermes (ALKS), converted/ exercised restricted stock units (derivative conversions) into 16,570 ordinary shares across Feb 18–19, 2026. To cover tax withholding obligations he surrendered/disposed of 6,911 shares (3,504 on 2/18 at $32.02, value $112,198; 3,407 on 2/19 at $32.00, value $109,024), for total withholding of $221,222. Net shares added to his position (after withholding) = 9,659 shares. These were routine conversions/withholdings, not open-market purchases or discretionary sales.

Context

• These transactions reflect RSU conversions with shares withheld to satisfy tax obligations (a common, routine administrative step), not an open-market sale intended as a liquidity event. For derivative/RSU transactions, conversion + withholding is effectively a cashless settlement to cover taxes; it shouldn't be interpreted alone as a bullish or bearish signal.
