System1 (SST) GC Daniel Weinrot Receives RSUs; Shares Withheld

What Happened
Daniel J. Weinrot, General Counsel & Secretary of System1, had 17,995 restricted stock units (RSUs) vest on July 15, 2026. To satisfy the tax withholding on that vesting, the company withheld 9,156 shares (disposition) valued at $2.60 each, totaling $23,806. This was a tax-withholding/cashless settlement of vested RSUs, not an open-market sale or purchase.

Key Details

  • Transaction date: 2026-07-15; withholding of 9,156 shares at $2.60 per share (total $23,806).
  • Transaction type/code: Tax withholding upon RSU vesting (code F).
  • Vested RSUs: 17,995 vested; 9,156 withheld to cover taxes (per footnote F1).
  • Unvested RSUs: Filing notes 36,515 unvested RSUs (per footnote F2).
  • Filing: Form 4 filed 2026-07-17; appears to be filed timely (within the standard two-business-day window).
  • The filing does not indicate an open-market sale — shares were retained by the company to satisfy tax liabilities.

Context
Withholding shares to cover taxes on RSU vesting is a routine, administrative step that reduces the insider's outstanding vested shares but does not necessarily signal a buy or sell decision. For retail investors, purchases or open-market sales by insiders tend to be more informative about sentiment; tax-related withholdings are procedural.
