Peterson Justin 4

What Happened

• Justin Peterson, Chief Technology Officer of Tradeweb Markets (TW), was granted restricted stock units (RSUs) and received a small shares settlement while 3,940 shares were withheld to cover tax obligations. The filing shows two grant transactions (8,037 RSUs and 29 shares) acquired at $0.00 and a tax-withholding disposition of 3,940 shares at $124.42 each (total ~$490,215).
• The RSUs are unvested awards subject to time-based vesting (multi-year schedules); the 3,940-share disposition represents shares surrendered/withheld to satisfy tax withholding associated with RSU settlement (not an open-market sale).

Key Details

• Transaction date: March 15, 2026; Form 4 filed March 17, 2026 (timely).
• Prices/values: Tax-withheld disposition of 3,940 shares at $124.42/share → ~$490,215. Grants recorded at $0.00 (typical for RSU awards).
• Vesting/footnotes: RSUs vest in equal installments over three years (see footnotes). Footnote details include: 2,548 RSUs vesting March 15, 2027; 6,728 RSUs vesting in installments on March 17, 2026–2028; and 8,037 RSUs vesting in installments on March 15, 2027–2029. A separate 29-share award reflects settlement of dividend-equivalent rights (DERs).
• Withholding: 3,940 shares were withheld to satisfy tax liabilities from RSU settlement (code F) — a tax-related disposition rather than a market sale.
• Shares owned after transaction: Not disclosed in the provided filing excerpt.

Context

• This is primarily a grant/settlement of RSUs with an associated tax withholding. Such withholding is routine for equity-based compensation and does not necessarily indicate the insider is reducing an investment stake.
