Tenable CFO Brown's RSU Settlement and Tax Withholding Details

According to the filing, the transactions reported by Brown on August 21, 2026 involved two steps. First, 14,544 restricted stock units were converted into an equivalent number of shares of Tenable Holdings common stock at a price of $0 per unit, a standard feature of RSU settlement. This brought his directly held common stock to 54,410 shares immediately following that transaction.

In the same day's second transaction, the issuer withheld 7,400 shares at a price of $34.38 per share to satisfy income tax withholding and remittance obligations connected to the net settlement of the RSUs. The filing states that this withholding "does not represent a sale." After this withholding, Brown's direct beneficial ownership of common stock stood at 47,010 shares, according to the filing.

The filing further discloses that each RSU represents a contingent right to receive one share of Tenable Holdings common stock. The remaining 174,536 RSUs are described as vesting in 16 equal quarterly installments over 4 years beginning November 21, 2025, subject to Brown's continuous service with the issuer as of each applicable vesting date, and subject to accelerated vesting in specified circumstances. The Form 4 was signed by David Bartholomew as attorney-in-fact on August 25, 2026.
