Arnold Timothy Gerald 4

What Happened

• Timothy Arnold, EVP, VB & President, Colonial at Unum Group, had 2,227 shares withheld to satisfy tax withholding on the vesting of 5,658 stock success units (SSUs). The withheld shares were valued at $71.64 each, totaling $159,542. This was a tax-withholding disposal (code F), not an open-market sale.

Key Details

• Transaction date: 2026-02-16; filing date: 2026-02-18 (timely filing).
• Withheld shares: 2,227 at $71.64 per share = $159,542.
• Vesting: 5,658 SSUs vested (third and final tranche from grant on 8/20/2020); net shares delivered on vesting ≈ 3,431 (5,658 vested − 2,227 withheld).
• Beneficial ownership after transaction (per footnotes): 39,791 shares of common stock plus 14,841 restricted stock units (RSUs) that convert 1-for-1 — approx. 54,632 shares if RSUs settle into stock. Footnote also notes ~18.212 shares acquired under the ESPP since the prior Form 4.
• Footnote context: SSUs were performance-based for the 1/1/2021–12/31/2025 period and are settled 1-for-1 in common stock. The withholding was to cover tax obligations on vesting.

Context

• This was a routine tax-withholding event tied to the vesting of performance/share units, not an indicator of a voluntary sale or market timing. For equity-derivative events like SSU vesting, withheld shares are commonly used to satisfy withholding obligations; they don’t necessarily reflect the insider’s view of the company’s stock.
