Whalen's November 2026 RSU Activity at F5, Inc.

According to the filing, the November 1, 2026 vesting encompassed shares from three distinct prior grants: 933 units from a November 1, 2023 award vesting in twelve equal quarterly increments beginning February 1, 2024; 718 units from a November 1, 2024 award vesting in twelve equal quarterly increments beginning February 1, 2025; and 668 units from a November 3, 2025 award vesting in twelve equal quarterly increments beginning February 1, 2026. The combined vesting of 2,319 shares brought Whalen's direct beneficial ownership to 39,467 shares before the withholding transaction.

The filing reports that 7,050 shares were then disposed of at $338.34 per share on November 1, 2026 under transaction code F, which corresponds to shares withheld for taxes upon vesting, reducing direct holdings to 32,417 shares. Each restricted stock unit, the filing states, "represents a contingent right to receive one share of F5, Inc. Common Stock on the vest date," subject to continued service through the applicable vest date.

The new 6,284 service-based RSU award granted November 2, 2026 is reported in Table II with a $0 acquisition price. Separately, the filing discloses a concurrent grant of Performance RSUs not reported in Table II; according to the filing, the underlying shares of Performance RSUs "will be reported in Table I if and when the Talent and Compensation Committee of the Board of Directors determines that the performance targets have been achieved." F5, Inc. is listed on NASDAQ:FFIV.

What Was Disclosed

Whalen's Form 4 covers RSU vestings and a new RSU grant between November 1 and November 2, 2026, plus a concurrent Performance RSU grant whose share count will depend on future performance determinations by the board's Talent and Compensation Committee.
