BLACK DOUG 4

What Happened

• Doug Black, CEO and Director of SiteOne Landscape Supply (SITE), had 2,009 restricted stock units (RSUs) convert into common shares on Feb 9, 2026. To satisfy tax withholding, 848 of those shares were surrendered at $145.65 per share, generating ~$123,511 in value. The filing shows the RSU conversion as derivative exercises (Form 4 code M) and the withholding as a tax withholding disposition (code F).

Key Details

• Transaction date: February 9, 2026; Form 4 filed February 11, 2026 (timely filing).
• RSUs converted: 2,009 shares (one-for-one conversion of vested RSUs).
• Shares withheld for taxes: 848 shares at $145.65 each, total ~$123,511.
• Relevant footnotes:
  • F1: RSUs convert into common stock one-for-one on vesting.
  • F2: Reporting person has indirect ownership via a family trust (spouse is trustee).

Context

• This was not an open-market sale or purchase by the insider; it was routine RSU vesting with a portion of shares surrendered to cover tax obligations (a common practice similar to a cashless withholding). Such tax-withholding dispositions are administrative and do not necessarily indicate a change in the insider’s view of the company.
