Equity [Abstract] |
Stockholders' Equity Note Disclosure | Shareholders' Equity Common Stock Repurchase On October 25, 2024, the Company announced that its Board of Directors authorized an additional $1.0 billion for its common stock share repurchase program. This authorization was incremental to the existing $6.4 billion program, initially approved in October 2010 and expanded in subsequent fiscal years. Acquisitions for the share repurchase programs will be made from time to time in private transactions, accelerated share repurchase programs, or open market purchases as permitted by securities laws and other legal requirements. The programs can be terminated at any time. The following table summarizes the Company's repurchases and retirements of its common stock under its Stock Repurchase Program (in thousands, except per share data):

Average price per share |  | $ | 299.34 |  |  | $ | 256.23 |  |  | $ | 261.83 |  |  | $ | 256.99 |

As of June 30, 2026, the Company had $422.4 million remaining authorized to purchase shares under its share repurchase program. Equity Incentive Plans On March 12, 2026, the Company adopted the F5, Inc. 2026 Incentive Award Plan, (the “2026 Plan”), which replaced the Company's F5, Inc. Incentive Plan adopted in 2022 (“the Plan”), and provides for discretionary grants of stock options, stock units, and other equity and cash-based awards for employees, including officers, directors, and consultants. The 2026 Plan authorizes the issuance of up to 5.4 million shares of the Company's common stock, which includes 1.9 million shares that remained available for issuance under the Plan and were transferred to the 2026 Plan. In addition, shares subject to outstanding awards under the Plan that subsequently expire, are forfeited, cancelled, or are settled in cash will become available for issuance under the 2026 Plan. No further awards will be granted under the Plan. However, all outstanding awards previously granted under the Plan will continue to be governed by the terms and conditions of the Plan and their respective award agreements. As of June 30, 2026, 5.4 million shares remained available for future grants under the 2026 Plan.
