Sanfilippo Thomas 4

What Happened

• Thomas Sanfilippo, Chief Technology Officer of WhiteFiber, reported sales of 2,455 ordinary shares to satisfy tax withholding on vested RSUs. The sales were: 1,500 shares on 2026-02-10 at an average price of $19.31 ($28,965) and 955 shares on 2026-05-07 at an average price of $21.00 ($20,055), totaling $49,020. These were tax-withholding (code F) transactions tied to RSU vesting and are not discretionary sales.

Key Details

• Transaction dates and prices:
  • 2026-02-10: 1,500 shares sold @ $19.31 (avg) = $28,965 (footnote F3).
  • 2026-05-07: 955 shares sold @ $21.00 (avg) = $20,055 (footnote F2).
• Total shares sold: 2,455; total proceeds: $49,020.
• Shares owned after the transactions: not specified in the provided filing.
• Footnotes:
  • F1: Sales were to pay tax liability upon RSU vesting under the 2025 Omnibus Equity Incentive Plan and “do not represent a discretionary transaction” by the reporting person.
  • F2/F3: Prices shown are the average sales prices for the respective sale dates.
• Filing timeliness: Form 4 was filed 2026-05-08 covering the Feb 10 and May 7 transactions; the Feb 10 sale was disclosed several months later (after the SEC’s usual 2-business-day reporting window), indicating a late-filed report for that transaction.

Context

• These transactions were cashless tax-withholding sales tied to RSU vesting (code F), not open-market discretionary sales; such routine withholding is common when restricted shares vest and generally does not by itself indicate insider sentiment about the stock.
• For retail investors tracking insider activity, purchases or discretionary sales can be more informative than mandatory tax-withholding sales; note this filing reflects the latter.
