Vintz Stephen A 4

What Happened

• Stephen A. Vintz, CEO of Tenable Holdings (TENB), reported derivative/RSU activity tied to performance- and time-based restricted stock units. The Form 4 shows conversions/settlements and a grant/award resulting from PRSU/RSU vesting.
• Key reported items: conversion/exercise entries for 24,381 shares (0.00 price) on Feb 25, 2026; 11,667 shares were withheld/disposed to satisfy tax withholding at $19.00/share (total $221,673) on Feb 25, 2026; and a grant/award of 341,847 derivative shares was reported as acquired on Feb 26, 2026. The exercise/conversion entries reflect conversion of RSUs/PRSUs to common stock; the withheld shares were remitted to the issuer for taxes (not an open-market sale).

Key Details

• Transaction dates: Feb 25, 2026 (conversion and tax withholding) and Feb 26, 2026 (award/grant); Form 4 filed Feb 27, 2026 (timely filing).
• Reported prices: conversions/exercises reported at $0.00; tax withholding shown at $19.00/share (11,667 shares withheld; $221,673).
• Shares owned after transaction: not specified in the provided filing summary.
• Notable footnotes:
  • F1: Share withholding was to satisfy income tax obligations for net settlement of RSUs (not a market sale).
  • F2: Each RSU equals a contingent right to one share of common stock.
  • F3: PRSUs certified Feb 25, 2026 with a 97.2% payout; 25% of PRSUs vested on Feb 25, 2026, remainder vest quarterly over three years (subject to service/acceleration).
  • F4: Time-based RSUs vest 25% on Feb 22, 2027, remainder quarterly over three years (subject to service/acceleration).

Context

• These transactions are primarily vesting/settlement of equity awards (PRSUs/RSUs). The withholding of 11,667 shares at $19/share was a tax-payment mechanism (issuer withheld shares), not an open-market sale; such withholdings are routine following vesting.
• The large grant/award entry reflects the PRSU/RSU payout and vesting schedule rather than a new open-market purchase or opportunistic insider buy.
