ACCO Brands (ACCO) director reports 2,961.7 RSU grant and 149K+ units held

Rhea-AI Filing Summary

ACCO Brands Corp director reports new equity grant. A board member of ACCO Brands Corp filed a Form 4 showing a grant of 2,961.7 restricted stock units (RSUs) of common stock on 12/10/2025 at an exercise price of $0. After this award, the director beneficially owns 149,465.13 derivative securities linked to ACCO common stock, held directly.

The RSUs were granted under ACCO’s incentive plan. They either vest immediately or on the one-year anniversary of the grant date, but in both cases are deferred under the company’s deferred compensation plan for non-employee directors. Each RSU converts into one share of ACCO common stock upon the earlier of the director’s death or disability, or when the director ceases to serve on the board.
