F5 Executive RSU Activity: Vesting, Tax Withholding, and New Grant Details

According to the filing, Thomas Dean Fountain, identified as EVP Global Services and Strategy of F5, Inc., reported two categories of transactions dated November 1, 2026 in Table I. First, 2,702 shares were acquired via transaction code M (conversion of derivative security) at $0, representing the vesting of portions of three separate service-based RSU awards originally granted on November 1, 2023, November 1, 2024, and November 3, 2025. Each of those awards vests in twelve equal quarterly increments. Second, 11,590 shares were disposed of at $338.34 per share under transaction code F, which the filing format designates as shares withheld by the issuer for tax withholding purposes, leaving Fountain with a direct beneficial holding of 17,447 shares of common stock.

In Table II, the filing reports the vesting of derivative securities corresponding to the three RSU awards. The 2023 award contributed 1,043 RSUs converted, leaving 0 remaining; the 2024 award contributed 951 RSUs converted, leaving 3,802; and the 2025 award contributed 708 RSUs converted, leaving 5,662. Each RSU represents a contingent right to receive one share of F5, Inc. common stock on the vest date, contingent on continued service, according to the filing.
