F5 Networks Announces Third Quarter Fiscal Year 2019 Results Including 91% Software Revenue Growth

Delivers GAAP EPS of $1.43 and non-GAAP EPS of $2.52 per diluted share

SEATTLE, WA — July 24, 2019 — F5 Networks, Inc. (NASDAQ: FFIV) today announced financial results for its fiscal 2019 third quarter ended June 30, 2019. Third quarter fiscal year 2019 results include the acquisition of NGINX, Inc., completed on May 8, 2019.

"The quarter's 4% total revenue growth and 91% software growth was driven by customer demand for the software form factors of our application services, as customers globally rely on F5 to provide consistent application security and reliable performance across private, public and multi-cloud environments," said François Locoh-Donou, F5 President and Chief Executive Officer. "With customers facing an ever-increasing array of threats, our software growth continues to be driven by security use cases, including web application firewall and bot-defense and mitigation."

"We continue to aggressively execute our strategy of expanding our reach and broadening our role while transitioning F5 to a software-driven model," continued Locoh-Donou." Customers are beginning to recognize a new F5 as a result of our reprioritization of development resources, introduction of new, flexible consumption models, and most recently, the acquisition and integration of NGINX."

Third Quarter Performance Summary

Revenue of $563.4 million for the third quarter of fiscal year 2019 reflects 4% growth from $542.2 million in the third quarter of fiscal year 2018, driven by total software solutions revenue growth of 91%, including a partial quarter contribution from NGINX.

GAAP net income for the third quarter of fiscal year 2019 was $85.9 million, or $1.43 per diluted share, and includes $41.0 million in stock-based compensation, $30.1 million in costs related to the acquisition of NGINX, $8.7 million in facility-exit costs and $3.7 million in amortization of purchased intangible assets. This compares with third quarter fiscal year 2018 GAAP net income of $122.7 million, or $1.99 per diluted share.

Non-GAAP net income for the third quarter of fiscal year 2019 was $151.5 million, or $2.52 per diluted share, compared to $150.1 million, or $2.44 per diluted share, in the third quarter of fiscal year 2018. Non-GAAP net income for the third quarter of fiscal year 2019 and the third quarter of fiscal year 2018 excludes the impact of stock-based compensation, and amortization of purchased intangible assets. Non-GAAP net income for the third quarter of fiscal year 2019 also excludes facility-exit costs related to the Company's headquarters move and costs related to the acquisition of NGINX.

A reconciliation of net income, earnings per share, and other measures on a GAAP to non-GAAP basis is included in the attached Consolidated Income Statements. Additional information about non-GAAP financial information is included below.

Business Outlook

For the fourth quarter of fiscal year 2019 ending September 30, 2019, the Company expects to deliver revenue in the range of $577 million to $587 million with non-GAAP earnings in the range of $2.53 to $2.56 per diluted share.

All forward-looking non-GAAP measures included in the 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, 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 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 of purchased intangible assets, acquisition-related charges, net of taxes, restructuring charges, facility-exit costs, significant litigation and other contingencies 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 ESPP. 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 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. 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.

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.

Facility-exit costs. In fiscal year 2019, F5 relocated its headquarters in Seattle, Washington and recorded charges in connection with this facility exit as well as other non-recurring lease activity. These charges are not representative of ongoing costs to the business and are not expected to recur. As a result, these charges are being excluded to provide investors with a more comparable measure of costs associated with ongoing operations.

Significant litigation and other contingencies. F5, from time to time, may incur charges or benefits that are outside of the ordinary course of F5's business related to litigation and other contingencies. F5 believes it is useful to exclude such charges or benefits, when significant, because it does not consider such amounts to be part of the ongoing operation of F5's business and because of the singular nature of the claims underlying such matters.

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 Consolidated Income Statements entitled "Non-GAAP Financial Measures."
