12. LONG-TERM DEBT

On the Closing Date, the Company entered into a credit agreement (the “Credit Agreement”), by and among Alkermes plc, as the TopCo Borrower, Alkermes, Inc., as the U.S. Borrower, Alkermes Finance LLC, as the U.S. Co-Borrower, JPMorgan Chase Bank, N.A., as Administrative Agent, Joint Lead Arranger and Joint Bookrunner, BofA Securities, Inc., as Joint Lead Arranger and Joint Bookrunner, and the lenders party thereto. The Credit Agreement provides for (i) a senior secured term loan A facility in an aggregate principal amount of up to $750.0 million (the “TLA Facility”) and (ii) a senior secured term loan B facility in an aggregate principal amount of up to $775.0 million (the “TLB Facility” and together with the TLA Facility, the “Facilities”). The TLA Facility matures on February 12, 2031, and the TLB Facility matures on August 12, 2031. On the Closing Date, the Company borrowed the full $1.525 billion available under the Facilities.

Borrowings under the TLA Facility will bear interest at an annual rate of, at the Company’s option, either (i) the Term SOFR Rate (as defined in the Credit Agreement) plus a Secured Net Leverage Ratio-(as defined in the Credit Agreement)-based margin, which will initially be 2.75% per annum or (ii) the Alternate Base Rate (as defined in the Credit Agreement) plus a Secured Net Leverage Ratio-based margin, which will initially be 1.75% per annum. Borrowings under the TLB Facility will bear interest at an annual rate of, at the Company’s option, either (i) the Term SOFR Rate plus a margin of 2.75% per annum or (ii) the Alternate Base Rate plus a margin of 1.75% per annum. The Company has agreed to pay certain fees and expenses in connection with the Facilities, as set forth in the Credit Agreement and certain related fee letters.

The Credit Agreement (other than with respect to the TLB Facility) requires the maintenance of a maximum Secured Net Leverage Ratio and a minimum Consolidated Interest Coverage Ratio (as defined in the Credit Agreement), in each case, with the levels set forth in the Credit Agreement, as of the last day of any fiscal quarter of the Company ending after the Closing Date. In addition, the Credit Agreement contains customary affirmative and negative covenants that apply after the Closing Date, including limitations on indebtedness, liens, mergers, consolidations, sales of assets, investments, transactions with affiliates, restricted payments and sales and leasebacks. The Credit Agreement also contains certain customary events of default, including upon a change of control.

The Credit Agreement is guaranteed by subsidiary guarantors and secured by a lien on substantially all of the assets of the borrowers and the subsidiary guarantors, whether owned as of the Closing Date or thereafter acquired.

In November 2025, the Company entered into an amended and restated bridge term credit agreement, which provided for a senior secured bridge term loan facility in an aggregate amount of up to approximately $1.5 billion (the “Bridge Credit Facility”) to fund a portion of the consideration for the Avadel Acquisition (the “Bridge Credit Agreement”). Loans under the Bridge Credit Facility were available, subject to the satisfaction of certain conditions set forth in the Bridge Credit Agreement, and were scheduled to mature on the date that is 364 days after the date on which the loans were funded under the Bridge Credit Facility. The commitments under the Bridge Credit Facility were to terminate on the earlier of (i) the date on which all of the consideration payable in respect of the Avadel Acquisition was paid in full without the making of any loans under the Bridge Credit Facility and (ii) the date on which a Mandatory Cancellation Event (as defined in the Bridge Credit Agreement) occurred or existed. Accordingly, on February 12, 2026, in connection with completion of the Avadel Acquisition and the Company’s entry into the Credit Agreement, the Company terminated the Bridge Credit Agreement, as the commitments under the Credit Agreement, together with the Company’s cash on hand, were sufficient to fund the Avadel Acquisition. During the three months ended March 31, 2026, the Company incurred approximately $7.7 million in financing costs related to the Bridge Credit Agreement which was recorded within “Interest expense” in the accompanying condensed consolidated statements of operations and comprehensive (loss) income.

The Company is subject to mandatory prepayments of principal if certain excess cash flow thresholds, as defined in the Facilities, are met. To date, the Company has not been required to make any such mandatory prepayments. The Facilities also contain customary affirmative covenants and events of default. The Company was in compliance with its debt covenants at March 31, 2026.

At March 31, 2026, the Company’s balance of unamortized deferred financing costs and unamortized original issue discount costs were $4.3 million and $12.0 million, respectively. These costs are being amortized to interest expense over the estimated repayment period of the Facilities using the effective interest method. During the three months ended March 31, 2026, the Company had amortization expense of $0.4 million related to deferred financing costs and original issue discount.
