Avadel (AVDL) CFO Thomas McHugh Sells Shares in Acquisition

What Happened
Thomas S. McHugh, Chief Financial Officer of Avadel Pharmaceuticals plc (AVDL), disposed of ordinary shares and related derivative awards on February 12, 2026 in connection with Alkermes plc’s acquisition of Avadel. The filing shows 100,400 ordinary shares converted into $21.00 per share cash, generating $2,108,400. Additional dispositions listed (250,000; 200,000; 150,000; 175,000; 157,500; 72,000 shares) represent derivative instruments (restricted stock awards and options) that were canceled or converted as part of the transaction; their reported per-item consideration is shown as N/A because they were settled under the merger terms.

Key Details

  • Price reported for ordinary shares: $21.00 per share for 100,400 shares = $2,108,400. Other entries are derivative conversions (no per-share cash shown in the Form 4).

    • F4: Outstanding options were canceled and exchanged for cash equal to (number of underlying shares × (Cash Consideration − exercise price)) and one CVR per underlying share.

Context
This was not an open-market sale driven by the insider’s discretionary trade but the result of a corporate acquisition: Avadel’s securities (ordinary shares, vested restricted awards and options) were settled per the merger agreement with Alkermes. Ordinary shares received $21.00 in cash plus a CVR for potential additional payment; options were canceled and converted to cash (formulaic) plus CVRs. Such deal-related dispositions are routine in change-of-control transactions and reflect the transaction mechanics rather than an independent insider view on the company’s prospects.
