Mason Heather L 4

What Happened

• Heather L. Mason, a director of Assertio Holdings, disposed of a total of 69,691 shares in connection with the company's sale and merger into Zydus Worldwide DMCC, effective June 16, 2026. Each outstanding share of common stock was cancelled and converted into the right to receive $23.50 per share in cash, so the aggregate consideration is approximately $1.64 million (before any applicable withholding taxes).
• The Form 4 shows four disposition lines: two "change of control" share dispositions (20,944 and 6,666 shares) and two dispositions to the issuer (36,666 and 5,415 shares) reflecting derivative awards converted under the merger (RSUs/options). Some lines report $0 or N/A in the filing format, but the footnotes confirm cash payment at the $23.50 offer price (less taxes).

Key Details

• Transaction date: 2026-06-16 (Effective Time of the merger). Offer Price: $23.50 per share.
• Shares disposed: 69,691 total (20,944; 6,666; 36,666; 5,415). Approximate cash received: $1.64M before withholding.
• Shares owned after transaction: Company common shares were cancelled at the Effective Time; insider no longer holds Assertio common stock.
• Notable footnotes: Dispositions occurred pursuant to the Merger Agreement and tender/merger offer. Unvested RSUs vested and were converted to cash; in-the-money options were cashed out per the agreement. Payments are subject to applicable withholding taxes.
• Filing timeliness: Reported for the transaction date (no late filing disclosed).

Context

• These were not open-market sales but merger-related conversions/cashouts: outstanding common shares were cancelled for cash, RSUs vested and paid out, and options with exercise prices below $23.50 were cashed out per the merger formula.
• This reflects a corporate liquidity event (acquisition) rather than a portfolio trade by the insider.
