Vintz Stephen A 4

What Happened

• Tenable CEO Stephen A. Vintz exercised/converted a series of restricted/performance stock unit derivatives (M), resulting in 27,413 shares issued on May 22, 2026. To satisfy tax withholding obligations, the issuer withheld 13,121 of those shares at $25.45 per share, totaling about $333,929. After withholding, Vintz received a net ~14,292 shares. These withholdings are tax remittances by the company and do not represent open-market sales.

Key Details

• Transaction date: May 22, 2026; Form 4 filed May 26, 2026 (no late filing indicated).
• Conversion price reported: $0.00 for the derivative-to-share conversion (typical for RSU/PRSU vesting); withholding price: $25.45 per share.
• Shares converted (gross): 27,413; shares withheld for taxes: 13,121 (~$333,929); net shares issued to reporting person: ~14,292.
• Additional note: 820 shares were acquired under the issuer’s Employee Stock Purchase Plan (ESPP) in exempt transactions per the filing.
• Footnotes explain these were RSUs/PRSUs (each RSU = one share), payout/vesting certification for PRSUs (payouts ~93.9%–97.2% across measurement periods), and that the withheld shares are to satisfy tax withholding (not open-market sales).

Context

• This was a vesting/net-settlement event (derivative conversion of RSUs/PRSUs with share withholding for taxes), effectively a cashless settlement to cover tax obligations. Such withholding is routine when equity awards vest and should not be read as an active sale by the insider.
