Alkermes plc completed its acquisition of Avadel Pharmaceuticals plc, gaining the FDA‑approved narcolepsy drug LUMRYZ and a commercial team experienced in sleep medicine. The deal was executed via an Irish court‑sanctioned scheme of arrangement.
Avadel shareholders became entitled to receive $21.00 in cash per share plus one contingent value right that may pay an additional $1.50 per share if a specified milestone in the CVR agreement is met. Avadel will be delisted from Nasdaq and deregistered under U.S. securities laws.
To finance the Acquisition, Alkermes borrowed $1.525 billion under new senior secured term loan A and B facilities maturing in 2031 and used approximately $750 million of its cash.
