F5 Reports Third Quarter Results with 19% Product Revenue Growth
Driving 11% Total Revenue Growth Year Over Year
SEATTLE, July 27, 2026 – F5, Inc. (NASDAQ: FFIV), the global leader in delivering and securing every app and API, today announced financial results for its third quarter fiscal year 2026 ended June 30, 2026.
“Q3 was another outstanding quarter with 19% product revenue growth driving 11% total revenue growth year over year,” said François Locoh-Donou, F5’s Chairman, President, and CEO. “Eight consecutive quarters of double-digit product growth reflect the mission-critical role F5 plays at the application delivery and security layer of today’s hybrid multicloud and AI-driven enterprise infrastructure.”
“The world runs on applications and the threats targeting them have never been more sophisticated. AI has empowered attackers and compressed the time between vulnerability discovery and exploitation. F5’s response is a continuous defense model built for this new reality. We are using AI to empower our customers to stay ahead of threats across every environment they operate in by identifying risk earlier, protecting applications at runtime, and delivering hardened software faster,” continued Locoh-Donou.

Third quarter fiscal year 2026 revenue totaled $865 million, representing 11% growth compared with $780 million in the third quarter of fiscal year 2025.

This compares with non-GAAP gross profit of $649 million in the year-ago period, which represented non-GAAP gross margin of 83.1%.
GAAP income from operations for the third quarter of fiscal year 2026 was $213 million, representing GAAP operating margin of 24.7%. This compares with GAAP income from operations of $196 million in the year-ago period, which represented GAAP operating margin of 25.2%. Non-

Business Outlook
F5 raised its outlook for its fiscal year 2026, guiding for revenue growth of approximately 9% to 10%, up from 7% to 8% previously. F5 expects non-GAAP earnings per share in a range of $17.21 to $17.33, up from $16.25 to $16.55 previously.
For the fourth quarter of fiscal year 2026, F5 is guiding to revenue in the range of $870 million to $890 million, with non-GAAP earnings in the range of $4.14 to $4.26 per diluted share.
All forward-looking non-GAAP measures included in the Company’s business outlook exclude estimates for amortization of intangible assets, share-based compensation expenses, significant effects of tax legislation and judicial or administrative interpretation of tax regulations (including the impact of income tax reform), non-recurring income tax adjustments, valuation allowance on deferred tax assets, and the income tax effect of non-GAAP exclusions, and do not include the impact of any future acquisitions or divestitures, acquisition-related charges and write-downs, cyber incident costs, insurance recoveries from cyber incident, restructuring charges, facility exit costs, or other non-recurring charges that may occur in the period. F5 is unable to provide a reconciliation of non-GAAP earnings guidance measures to corresponding U.S. generally accepted accounting principles or GAAP measures on a forward-looking basis without unreasonable effort due to the overall high variability and low visibility of most of the foregoing items that have been excluded. Material changes to any one of these items could have a significant effect on our guidance and future GAAP results. Certain exclusions, such as amortization of intangible assets and share-based compensation expenses, are generally incurred each quarter, but the amounts have historically varied and may continue to vary significantly from quarter to quarter.

qualified in their entirety by this cautionary statement. F5 assumes no obligation to revise or update these forward-looking statements.
GAAP to non-GAAP Reconciliation
F5’s management evaluates and makes operating decisions using various operating measures. These measures are generally based on the revenues of its products, services operations, and certain costs of those operations, such as cost of revenues, research and development, sales and marketing and general and administrative expenses. One such measure is GAAP net income excluding, as applicable, stock-based compensation, amortization and impairment of purchased intangible assets, facility-exit costs, acquisition-related charges, cyber incident costs, insurance recoveries from cyber incident, restructuring charges, net of tax effects, as well as certain non-recurring tax expenses and benefits, which is a non-GAAP financial measure under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended. This measure of non-GAAP net income is adjusted by the amount of additional taxes or tax benefit that the Company would accrue if it used non-GAAP results instead of GAAP results to calculate the Company’s tax liability.
The non-GAAP adjustments, and F5's basis for excluding them from non-GAAP financial measures, are outlined below:
Stock-based compensation. Stock-based compensation consists of expense for stock options, restricted stock, and employee stock purchases through the Company’s Employee Stock Purchase Plan. Although stock-based compensation is an important aspect of the compensation of F5’s employees and executives, management believes it is useful to exclude stock-based compensation expenses to better understand the long-term performance of the Company’s core business and to facilitate comparison of the Company’s results to those of peer companies.
Amortization and impairment of purchased intangible assets. Purchased intangible assets are amortized over their estimated useful lives and generally cannot be changed or influenced by management after the acquisition. On a non-recurring basis, when certain events or circumstances are present, management may also be required to write down the carrying value of its purchased intangible assets and recognize impairment charges. Management does not believe these charges accurately reflect the performance of the Company’s ongoing operations; therefore, they are not considered by management in making operating decisions. However, investors should note that the use of intangible assets contributed to F5’s revenues earned during the periods presented and will contribute to F5’s future period revenues as well.
Facility-exit costs. F5 has incurred certain non-recurring right-of-use asset impairment charges, and other related recurring costs in connection with the exit of its leased facilities. These charges are not representative of the ongoing activity or costs to the business. As a result, these charges are being excluded to provide investors with a more comparable measure of costs associated with ongoing operations.
Acquisition-related charges, net. F5 does not acquire businesses on a predictable cycle, and the terms and scope of each transaction can vary significantly and are unique to each transaction. F5 excludes acquisition-related charges from its non-GAAP financial measures to provide a useful comparison of the Company’s operating results to prior periods and to its peer companies. Acquisition-related charges consist of planning, execution and integration costs incurred directly as a result of an acquisition.
Cyber incident costs. F5 has incurred certain non-recurring expenses in connection with the investigation and remediation of the Cyber Incident. Management believes it is useful to exclude these expenses as they are not representative of our ongoing operations and to facilitate comparison of the Company’s historical results and to those of peer companies.
Insurance recoveries from cyber incident. F5 has received insurance recoveries in connection with the cyber incident costs described above. Management believes it is useful to exclude these recoveries as they offset
Q3 FY26 Earnings Release
Page 5 of 5
the cyber incident costs non-GAAP adjustment, are not representative of our ongoing operations and to facilitate comparison of the Company's historical results and to those of peer companies.
Restructuring charges. F5 has incurred restructuring charges that are included in its GAAP financial statements, primarily related to workforce reductions and costs associated with exiting facility-lease commitments. F5 excludes these items from its non-GAAP financial measures when evaluating its continuing business performance as such items vary significantly based on the magnitude of the restructuring action and do not reflect expected future operating expenses. In addition, these charges do not necessarily provide meaningful insight into the fundamentals of current or past operations of its business.
Management believes that non-GAAP net income per share provides useful supplemental information to management and investors regarding the performance of the Company’s core business operations and facilitates comparisons to the Company’s historical operating results. Although F5’s management finds this non-GAAP measure to be useful in evaluating the performance of the core business, management’s reliance on this measure is limited because items excluded from such measures could have a material effect on F5’s earnings and earnings per share calculated in accordance with GAAP. Therefore, F5’s management will use its non-GAAP earnings and earnings per share measures, in conjunction with GAAP earnings and earnings per share measures, to address these limitations when evaluating the performance of the Company’s core business. Investors should consider these non-GAAP measures in addition to, and not as a substitute for, financial performance measures in accordance with GAAP.
F5 believes that presenting its non-GAAP measures of earnings and earnings per share provides investors with an additional tool for evaluating the performance of the Company’s core business and is used by management in its own evaluation of the Company’s performance. Investors are encouraged to look at GAAP results as the best measure of financial performance. However, while the GAAP results are more complete, the Company provides investors these supplemental measures since, with reconciliation to GAAP, it may provide additional insight into the Company’s operational performance and financial results.
For reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section in our attached Condensed Consolidated Income Statements entitled “Non-GAAP Financial Measures.”
