Filing notes and footnotes

Explanation of responses 6 footnotes

Footnote F1

Shares acquired upon the vesting of the November 3, 2025 award of service-based Restricted Stock Units.

Footnote F2

Each Restricted Stock Unit represents a contingent right to receive one share of F5, Inc. Common Stock on the vest date.

Footnote F3

This November 3, 2025 award of service-based Restricted Stock Units vests in twelve equal quarterly increments beginning February 1, 2026.

Footnote F4

If the reporting person continues to provide services to the Company through the vest date, the corresponding number of shares of Common Stock of F5, Inc. will be issued to the reporting person on the vest date.

Footnote F5

Concurrent with the award of 4,265 service-based Restricted Stock Units, the Company granted the reporting person additional Restricted Stock Units, the number of which that can be earned will be based on performance targets ("Performance RSUs"). If the performance targets are achieved at 100%, the reporting person can receive 4,265 Performance RSUs over the vesting period; the actual number of Performance RSUs received may be more or less depending on whether and to the extent that performance is greater than or less than targets and may be less if the reporting person does not remain employed during the vesting period. Performance RSUs are not reported in Table II; 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.

Footnote F6

This November 2, 2026 award of service-based Restricted Stock Units vests in twelve equal quarterly increments beginning February 1, 2027.
