F5 (FFIV) Director Elizabeth Buse Exercises Derivatives, Receives Award

What Happened

Elizabeth Buse, a director of F5, Inc. (FFIV), had a set of derivative/award transactions: on 2026-03-11 she exercised/converted 934 derivative units (reported as code M) at $0.00 and a corresponding disposition of 934 derivative units at $0.00. On 2026-03-12 she was issued/awarded 987 restricted stock units (RSUs) (reported as code A) at $0.00. All reported transaction prices are $0.00, indicating these were internal derivative conversions/awards rather than open-market buys or sales.

Key Details

Transaction dates and codes:
- 2026-03-11: M (exercise/conversion of derivative) — 934 units acquired @ $0.00; 934 units disposed @ $0.00 (derivative).
- 2026-03-12: A (award/grant) — 987 RSUs acquired @ $0.00 (derivative).
Report filed: 2026-03-13 (the filing covers the 3/11–3/12 transactions).
Shares owned after transaction: Not specified in the filing.
Footnotes:
- F1–F4 indicate these are Restricted Stock Units (each RSU equals a contingent right to one share on vesting).
- Vesting is tied to the company’s annual shareholder meeting schedule and requires the director to continue service through the vest date (see F2 and F4).
No indication of a 10b5-1 plan or tax-withholding detail is provided in the filing.

Context

These entries involve RSUs and conversion of derivative units, not open-market purchases or market sales. RSUs are contingent awards that convert to actual shares on the stated vesting date (per the footnotes), so the 987 RSUs granted on 3/12 are not immediately tradable shares.
The 3/11 conversion/disposition recorded at $0.00 reflects internal conversion/processing of derivative awards rather than a cash sale; the filing does not state any cash proceeds.
