Insights

Takeover disclosure analyst

Alkermes disclosed an opening position under Irish Takeover Rules as offeror in relation to Avadel; holdings reported are effectively nil.

Alkermes filed an opening position disclosure under Rule 8.1(a)/(b) naming Avadel Pharmaceuticals plc as the offeree and reporting the position date as 3 November 2025, with the public disclosure dated 5 November 2025. The form shows no direct interests or short positions by the discloser in the relevant securities and states that persons acting in concert (J.P. Morgan and related staff) hold a combined 0.0139% of ordinary shares (13,553 shares).

The document records no indemnities, arrangements, or derivative agreements and notes no Supplemental Form 8. That limits the factual content to a procedural opening-position disclosure and a minor, disclosed holding by advisers; there are no stated commitments or option arrangements to change the position.

Watch for any attached Supplemental Form 8, corrective disclosures, or later filings that change the holdings or state transaction terms; these would appear imminently under the same takeover disclosure regime. The immediate timeframe for such updates is days to weeks following this 5 November 2025 disclosure.
