Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On October 24, 2025, F5’s Board of Directors (the “Board”) determined that current Chief Executive Officer and President, François Locoh-Donou, would assume the additional role of Chair of the Board following the Company’s next Annual Meeting of Shareholders, which is expected to be held in March 2026. Mr. Locoh-Donou will succeed current Chair, Alan J. Higginson, who, as previously announced, will be retiring after nearly 30 years as a Company director and 20 years as the Company’s Chair. At that time, the Board will also appoint a lead independent director as part of the transition to ensure independent oversight.

Actual results and events could differ materially from those conveyed in the forward-looking statements as a result of certain risk factors. Such forward-looking statements involve risks and uncertainties, as well as assumptions and other factors that, if they do not fully materialize or prove correct, could cause the actual results, performance, events (including Chair succession) or achievements of the Company to be materially different from any future results, performance, events or achievements expressed or implied by such forward-looking statements. Such factors include, but are not limited to: changes in the details and timing of Chair succession and related Board actions and other risks and uncertainties described more fully in our documents filed with or furnished to the Securities and Exchange Commission, including our most recent reports on Form 10-K and Form 10-Q and current reports on Form 8-K and other documents that we may file or furnish from time to time, which could cause actual results to vary from expectations. All forward-looking statements in this press release are based on information available as of the date hereof and qualified in their entirety by this cautionary statement.
