BURTON JOSEPH B 4

What Happened Joseph B. Burton, a member of ACCO Brands Corp.'s Board of Directors, received a grant of 32,809 restricted stock units (RSUs) on 2026-05-19. The Form 4 lists the acquisition as a derivative award (code A) at $0.00 per unit (reported value $0 on the form). These RSUs represent rights to receive one share per RSU upon the earlier of death/disability or cessation of board service and have been deferred under the Issuer’s Deferred Compensation Plan for Non-Employee Directors.

Key Details

• Transaction date: 2026-05-19 (reported on Form 4 filed 2026-05-20) — filing appears timely.
• Instrument/type: 32,809 RSUs (derivative award, transaction code A) reported at $0.00 per unit.
• Shares owned after transaction: Not specified in the provided filing.
• Footnote: RSUs vest either immediately or on the one-year anniversary of the grant but are deferred; each RSU equals the right to one share upon the earlier of death/disability or end of board service (see F1).
• No sale or purchase occurred — this is a compensation grant, not an open-market trade.

Context RSU grants to non-employee directors are a common form of board compensation and are not the same as an outright purchase (which can be viewed as a stronger bullish signal). Because these RSUs are deferred and tied to continued board service (or certain contingencies), they primarily reflect compensation arrangements rather than an immediate change in the director’s stake or market-facing trading behavior.
