OCONNOR DEBORAH A 4

What Happened

• Deborah A. O'Connor, EVP and Chief Financial Officer of ACCO Brands, had 94,019 restricted stock units (RSUs) convert into common shares on March 14, 2026. The RSU conversion shows an acquisition of 94,019 shares at a $0.00 exercise price (this reflects vesting/conversion rather than a cash purchase).
• To satisfy tax withholding, 27,548 of those shares were withheld/disposed at an effective value of $3.32 per share, totaling $91,459. Net shares retained from this vesting event: 94,019 − 27,548 = 66,471 shares.

Key Details

• Transaction date: 2026-03-14.
• Conversion/acquisition: 94,019 shares @ $0.00 (derivative conversion of RSUs; transaction code M).
• Tax withholding: 27,548 shares withheld/disposed @ $3.32 = $91,459 (transaction code F).
• Footnote: These were RSUs granted under the issuer’s incentive plan; each RSU converts to one share on March 14, 2026 if employment conditions are met.
• Filing: No late filing is indicated in the information provided.

Context

• This was a routine vesting/conversion of RSUs, not an open-market purchase or a voluntary sale. The withholding of shares to cover taxes is common and does not necessarily signal the insider’s view on the stock.
• Transaction codes: M = exercise/conversion of a derivative (here, RSU conversion); F = payment of exercise price or tax liability (share withholding). Purchases by insiders tend to be more informative about sentiment than routine vesting events.
