WHITMAN MARGARET C 4

What Happened

• Margaret C. Whitman, a director of CoreWeave, had restricted stock units (RSUs) converted/exercised into a total of 1,320 shares on 2026-03-14 (1,200 + 120). The Form 4 also reports dispositions of the same 1,320 shares on the same date. No per-share prices or total dollar values were reported (listed as N/A).

Key Details

• Transaction date: March 14, 2026; Form 4 filed March 17, 2026.
• Transactions reported: Exercise/conversion of derivative securities (code M) — Acquired 1,200 and 120 shares; Disposed 1,200 and 120 shares (derivative).

• Shares owned after transaction: Not disclosed in the filing.
• Footnotes of note:
  • F1: Each RSU converts to one share upon settlement.
  • F2/F4: Awards vest ratably on quarterly vesting dates (some awards vest ~1/12 each quarter; others ~1/4 each quarter), with first tranche vested June 14, 2025.
  • F3: These RSUs do not expire; they either vest or are cancelled prior to the vesting date.
• Filing timeliness: Form filed March 17, 2026; the filing does not indicate a late-report flag.

Context

• The filing shows conversion of RSUs into shares and simultaneous dispositions of the same number of shares. This pattern commonly reflects company withholding or share surrender to satisfy tax obligations upon vesting, though the Form 4 itself does not state the purpose of the dispositions. These transactions are not open-market purchases or sales expressing a buy/sell decision by the insider, but rather settlement and related disposition of equity awards.
