What Happened Richard Jonathan Hart, Chief Legal Officer and Chief Administrative Officer of Acadian Asset Management Inc. (AAMI), had restricted stock units (RSUs) vest and convert into common shares on Feb 14–15, 2026. A total of 15,305 RSU shares converted to common stock (5,755 on Feb 14 and 9,550 on Feb 15). To cover tax withholding, 2,782 shares were withheld/sold on Feb 14 (at $51.85 each, $144,247) and 4,618 shares were withheld/sold on Feb 15 (at $51.85 each, $239,443), for total withholding proceeds of $383,690.

Key Details

• Transactions filed: Form 4 filed Feb 18, 2026 covering transactions dated Feb 13–15, 2026.
• Vesting/conversion: 5,755 shares converted (Feb 14) and 9,550 shares converted (Feb 15) from previously granted RSUs — total converted = 15,305 shares.
• Tax withholding (dispositions): 2,782 shares withheld/sold on Feb 14 at $51.85 ($144,247); 4,618 shares withheld/sold on Feb 15 at $51.85 ($239,443). Total withheld = 7,400 shares / $383,690.
• Net shares retained from these conversions: 15,305 converted − 7,400 withheld = 7,905 net new shares added to Hart’s holdings (separate from the unvested 21,602 RSU grant).
• New grant (Feb 13, 2026): 21,602 RSUs (see footnote) vesting in equal annual installments over three years (1/3 on Feb 13 each year 2027–2029).
• Relevant footnotes: F1 explains each RSU equals one share; F2–F4 describe the vesting schedules of the Feb 13, 2026 grant and prior grants whose vesting triggered the Feb 14–15 conversions.
• Filing timing: Filed Feb 18 for mid-February transactions; the earliest transactions (Feb 13–14) appear to fall outside the Form 4 two-business-day reporting window and may be late — the filing does not include an explicit timeliness flag in the materials provided here.

Context

• These actions are routine RSU vesting and settlement, not an open-market purchase. RSUs convert to shares at no cash exercise price; Hart satisfied tax withholding by having shares withheld/sold (a common cashless/stock-withholding settlement).
• Such withholdings are tax-related dispositions and do not necessarily indicate a change in the insider’s view of the company.
