What Happened

Anschutz Barron, Tenable’s Chief Accounting Officer, had RSUs convert (exercise/conversion) on May 22, 2026. A total of 4,223 RSUs converted into common shares. The issuer withheld 2,021 shares to cover tax withholding at $25.45/share (total withheld value $51,435), leaving a net issuance of 2,202 shares to the reporting person (net value at $25.45 ≈ $56,038).

Key Details

Transaction date: May 22, 2026; Form 4 filed May 26, 2026 (filed within the SEC’s 2-business-day window).
Codes: M = exercise/conversion of derivative (RSU conversion); F = shares withheld for tax withholding (not a sale).

- Converted: 1,337; 1,258; 1,628 (total 4,223)
- Withheld for taxes: 640; 602; 779 (total 2,021) at $25.45/share = $51,435
- Net issued to insider: 2,202 shares (net value ≈ $56,038 at $25.45)

Footnotes: issuer withheld shares to satisfy income tax withholding on net-settled RSUs (this withholding is not a market sale). RSUs represent contingent rights to one share each; vesting schedule notes 25% initial vest and remaining vesting in quarterly installments over three years.

Context

This was a routine RSU vesting and net settlement (issuer withheld shares to cover taxes). That withholding is administrative and does not necessarily indicate a decision to sell shares in the open market.
For retail investors, vesting events increase insider-held shares but tax-withholding via share retention is common and not a bearish signal.
