SEATTLE, WA - F5, Inc. (NASDAQ: FFIV) today announced financial results for its second quarter ended March 31, 2024.

“We delivered a solid second quarter, with revenue near the midpoint of our guidance range and earnings per share at the high end of our guidance in an environment where customers remain cautious and are forecasting largely flat IT budgets for calendar 2024,” said François Locoh-Donou, F5’s President and CEO. “During the quarter, our software subscription renewals continued to perform well, driving 20% total software revenue growth compared to a year ago, including 28% subscription revenue growth.”

“To move at the speed of business today, our customers rely on an ever-increasing number of applications and APIs which they operate across distributed environments. This hybrid and multicloud reality brings with it untenable operational complexity, considerable costs, and escalating security risks. Broad-based enterprise adoption of AI will only compound these challenges,” said Locoh-Donou. “F5 solves these challenges, providing the most effective and comprehensive application and API security platform in the industry. We also empower customers to radically simplify their disparate infrastructure environments and applications.”

Business Outlook

For the third quarter of fiscal year 2024, F5 expects to deliver revenue in the range of $675 million to $695 million, with non-GAAP earnings in the range of $2.89 to $3.01 per diluted share.

In addition, the Company expects fiscal year 2024 revenue growth that is flat to down 2% compared to fiscal year 2023. This outlook is consistent with its prior outlook for fiscal year 2024 revenue growth of “flat to low-single-digit decline” compared to the prior year. In addition, the Company raised its fiscal year 2024 non-GAAP earnings per share outlook to growth of 7% to 9% from its prior range of growth of 6% to 8%.

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, 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.

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, net of taxes, restructuring charges, and 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.

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.”
