Item 2.02Results of Operations and Financial Condition

On April 19, 2023, F5, Inc. (the "Company") issued a press release regarding its financial results for the second quarter ended March 31, 2023. The press release is attached hereto as Exhibit 99.1. The information in the press release shall not be treated as filed for purposes of the Securities Exchange Act of 1934, as amended.

Item 2.05Costs Associated with Exit or Disposal Activities

On April 19, 2023, the management of the Company initiated cost adjustments to better align strategic and financial objectives, optimize operations, and drive efficiencies for long-term growth and profitability, including a reduction in force affecting approximately 620 employees, or approximately 9% of the Company’s global workforce as of April 19, 2023. As part of the restructuring, the Company also expects to reduce its leased facilities. The Company estimates the expenses associated with the headcount reductions will result in annualized savings of approximately $130 million. The Company expects it will incur approximately $45 million in severance benefits costs related to restructuring and other charges related to these actions in fiscal year 2023. The Company will also reduce some of its leased facilities space, consisting of lease termination and other facility costs. The Company is not able to estimate the cost of the reductions to leased facilities at this time. Potential position reductions are subject to legal requirements that vary by jurisdiction, which may extend the reduction process beyond fiscal year 2023 in certain cases. The charges that the Company expects to incur regarding the force reduction and other actions are subject to a number of assumptions, including legal requirements in various jurisdictions, and actual expenses may differ materially from the estimates disclosed above.

Item 7.01Regulation FD Disclosures

A letter to the Company’s employees from François Locoh-Donou, the Company’s Chief Executive Officer and President, regarding the costs adjustment plan is attached hereto as Exhibit 99.2. The information in the letter shall not be treated as filed for purposes of the Securities Exchange Act of 1934, as amended.

This report, including the exhibits attached hereto, contains forward-looking statements (such as our expectations), including, among other things, statements regarding the amount and timing of the expected actions and charges related to the announced costs adjustment plan. These forward-looking statements are subject to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and of Section 21E of the Securities Exchange Act of 1934, as amended. Actual results could differ materially from those projected in the forward-looking statements as a result of certain risk factors, including but not limited to, the Company’s ability to successfully implement the costs adjustment plan, including reduction in force and lease space reduction; possibl
