COOK WILLIAM M 4

What Happened
William M. Cook, a director of Mativ Holdings, received a total of 22,516 deferred stock units on July 1, 2026 (awards of 1,075; 658; 968; and 19,815 units). No purchase price or cash changed hands — these are awarded/deferred equity units granted as part of non-employee director compensation and reported on a Form 4 filed July 6, 2026. The filing lists the transactions as derivative awards (stock units), not open-market buys or sales.

Key Details

• Transaction date: 2026-07-01; Form 4 filed: 2026-07-06. (This appears to be filed after the typical two-business-day Form 4 deadline.)
• Share/units granted: 1,075; 658; 968; and 19,815 — total 22,516 deferred stock units. Price: N/A (award/deferral).
• Shares owned after the transaction: not specified in the filing.
• Footnote summaries:
  • F1/F5: Quarterly/annual director retainers were deferred under the Non-Employee Directors Deferred Compensation Plan.
  • F2: Deferred stock units convert to shares upon retirement or termination as a director.
  • F3/F4: Amounts include reinvested dividend equivalents on deferred/vested units.
• Transaction code: A = Award/Grant (derivative stock units).

Context
These awards are routine non-employee director compensation (deferred stock units) and do not represent open-market buying or selling. Deferred units typically convert into company shares upon a director’s retirement or departure, so this filing reflects compensation mechanics rather than an immediate investment decision. The late filing (filed July 6 for a July 1 transaction) is an administrative detail investors may note; it does not change the nature of the award.
