WHALEN CHAD MICHAEL 4

What Happened

• Chad Whalen, EVP Worldwide Sales of F5, Inc. (FFIV), received 2,317 shares upon the vesting/conversion of restricted stock units (RSUs) on February 1, 2026. To satisfy withholding for tax obligations, 941 of those shares were surrendered at a per‑share value of $275.61 for total tax withholding of $259,349.
• The filing shows the vesting/conversion reported as multiple derivative transactions (667, 717 and 933‑share conversions, which sum to the 2,317 shares). The tax withholding is reported under code F; the conversions are reported under code M.

Key Details

• Transaction date: February 1, 2026; Filing date: February 3, 2026 (no late filing indicated in the report).
• Vesting breakdown: three RSU conversions of 667, 717 and 933 shares (total 2,317).
• Tax withholding: 941 shares surrendered at $275.61 each, totaling $259,349.
• Transaction codes: M = conversion/exercise of derivative (RSU conversion), F = payment of tax liability (share withholding).
• Footnotes: Shares arose from service‑based RSU awards (Nov 1, 2023; Nov 1, 2024; Nov 3, 2025) that vest in quarterly increments (see footnotes F1–F6). Each RSU equals one share on the vest date.
• Shares owned after the transaction: not specified in the provided filing details.

Context

• This was an RSU vesting event with shares withheld to cover taxes (a routine, non‑market sale). No open‑market sale or purchase by the insider is reported — the disposal was solely for tax withholding.
• For retail investors: RSU vesting is common compensation; withholding to cover taxes is standard and does not necessarily indicate a change in the insider’s view of the company.
