Alkermes plc Amends Credit Agreement, Lowers Term Loan Interest Spreads

What Happened

• Alkermes plc announced on August 12, 2026 that it entered into Amendment No. 1 to its Credit Agreement (originally dated February 12, 2026) with its lenders, including JPMorgan Chase Bank, N.A. as Administrative Agent. The credit facilities consist of a senior secured Term Loan A (TLA) and Term Loan B (TLB).
• Outstanding principal amounts are $745,312,500 for the TLA and $773,062,500 for the TLB. The TLA matures on February 12, 2031 and the TLB matures on August 12, 2031.

Key Details

• Amendment effective date: August 12, 2026. Full amendment is filed as Exhibit 10.1 to the 8-K.
• Interest spread reductions: TLA spread lowered by 0.75%; TLB spread lowered by 0.50%.
• Post-amendment pricing:
  • TLA: either Term SOFR + margin of 1.75%–2.25% (margin varies by secured net leverage ratio) or Alternate Base Rate + margin of 0.75%–1.25%.
  • TLB: either Term SOFR + 2.25% or Alternate Base Rate + 1.25%.

Why It Matters

• The amendment reduces Alkermes’ borrowing costs on its two large term loans, which can lower interest expense and improve cash flow versus prior pricing.
• Maturities remain unchanged (Feb 2031 for TLA, Aug 2031 for TLB), so the company’s repayment timeline is not extended; this is a cost reduction rather than a maturity concession.
• This is a material financing development (Item 1.01) for investors monitoring Alkermes’ debt profile and interest expense, and the full amendment is available in the filed exhibit for review.
