Alkermes plc Appoints New Director Anne C. Whitaker to Board

What Happened Alkermes plc (ALKS) filed an 8-K reporting that on September 14, 2026 the Board increased its size from ten to eleven directors and appointed Anne C. Whitaker as a director, effective immediately. Her initial term runs through the Company’s 2027 annual general meeting. The Company also issued a press release about the appointment on September 16, 2026.

Key Details

• Board change: increased from 10 to 11 directors; Anne C. Whitaker appointed effective September 14, 2026.
• Compensation: Whitaker will receive the standard annual cash retainer and annual equity grant per the Company’s director compensation policy.
• New director award: an initial equity award with an aggregate target value of $600,000 (50% stock options, 50% restricted stock units); vests/exercisable in three equal annual installments beginning on the first anniversary of grant, subject to continuous service. The award is expected to be granted in October 2026 on the Company’s monthly new-hire grant date. Exercise price for options = closing Nasdaq price on grant date.
• Governance and legal: Whitaker has not been appointed to any Board committees as of the filing date. Alkermes and its subsidiary entered into indemnification agreements with her in forms previously filed with the SEC. The filing states she has not been involved in any related-party transactions reportable under Item 404(a) since January 1, 2025.

Why It Matters This filing is a governance update — a new independent director can affect board expertise, oversight and future strategic decisions. The $600,000 initial equity package and standard retainer align her economic incentives with shareholders and will vest over three years, which is relevant for dilution and executive alignment considerations. Investors tracking board composition, corporate governance, or potential changes in oversight should note the appointment and the timing of the expected equity grant.
