Lundbeck has entered the fray with an unsolicited takeover proposal for Avadel, offering up to $23.00 per ordinary share. The offer consists of $21.00 in cash at closing and a $2.00 contingent value right (CVR) that will activate if Avadel meets specified sales milestones. The CVR structure mirrors the one used in Lundbeck’s earlier deals, tying additional payments to commercial performance rather than a fixed premium.
Alkermes’ original offer, announced on October 22, 2025, capped at $20.00 per share and included $18.50 in cash plus a $1.50 CVR linked to FDA approval of LUMRYZ for idiopathic hypersomnia by the end of 2028. The higher price and larger cash component of Lundbeck’s bid immediately raise the question of whether Alkermes will increase its offer or pursue alternative strategies. The two CVR mechanisms underscore the importance of LUMRYZ’s commercial trajectory and regulatory milestones in determining the final valuation.
LUMRYZ, Avadel’s flagship once‑at‑bedtime oxybate for narcolepsy, is the linchpin of this transaction. Its FDA approval in May 2023 and subsequent pediatric approval in October 2024, coupled with orphan drug designation for idiopathic hypersomnia in June 2025, position the drug as a high‑growth asset in a niche market. For Lundbeck, acquiring LUMRYZ expands its sleep‑medicine portfolio and aligns with its “Focused Innovator” strategy, while for Alkermes, the deal would accelerate entry into the sleep‑medicine segment and complement its broader neuroscience pipeline.
The announcement has already sparked a flurry of analyst commentary. Many note that the higher bid reflects Lundbeck’s aggressive pursuit of assets that can generate incremental revenue streams and that the potential for a bidding war could drive the final price even higher. Analysts also point out that the CVR structures in both offers signal a shared emphasis on performance‑based upside, which could mitigate upfront cash outlays for both parties.
With the deal expected to close in the first quarter of 2026, both companies are now navigating a complex landscape. Alkermes is reviewing its options with advisers, weighing the merits of a counter‑offer against the possibility of a higher bid from Lundbeck. Avadel’s board has signaled that the Lundbeck proposal could qualify as a “Company Superior Proposal,” allowing it to negotiate while still bound by its agreement with Alkermes. The outcome will hinge on the relative valuations, the speed of regulatory approvals, and the ability of each bidder to meet the CVR milestones.
The strategic implications extend beyond the immediate transaction. A successful acquisition would give Alkermes a foothold in the sleep‑medicine market, while a Lundbeck win would reinforce its portfolio diversification strategy. Either outcome would reshape the competitive dynamics in the niche of narcolepsy and idiopathic hypersomnia treatments, potentially setting a precedent for future M&A activity in this specialized therapeutic area.
