F5 Networks Announces Results for Third Quarter of Fiscal 2015

SEATTLE, WA - July 22, 2015 - For the third quarter of fiscal 2015, F5 Networks, Inc. (NASDAQ: FFIV) announced revenue of $483.6 million, up 2 percent from $472.1 million in the prior quarter and 10 percent from $440.3 million in the third quarter of fiscal 2014.

GAAP net income was $93.2 million ($1.29 per diluted share), compared to $85.7 million ($1.18 per diluted share) in the prior quarter and $79.5 million ($1.05 per diluted share) in the third quarter a year ago.

Excluding the impact of stock-based compensation and amortization of purchased intangible assets, non-GAAP net income was $120.2 million ($1.67 per diluted share), compared to $115.3 million ($1.59 per diluted share) in the prior quarter and $104.6 million ($1.39 per diluted share) in the third quarter of last year.

A reconciliation of GAAP net income to non-GAAP net income is included on the attached Consolidated Statements of Operations.

"Solid sequential and year-over-year revenue growth during the quarter was driven primarily by continuing growth in software sales," said Manny Rivelo, F5 President and Chief Executive Officer. "Within the past three years, quarterly revenue from the sale of software modules and virtual editions has more than doubled, accounting for more than a third of product revenue in Q3. As more of our customers deploy hybrid solutions and adoption of our software modules increases, we believe this trend will continue, augmented by a steady ramp in sales of our cloud-based Silverline subscription offerings.

"From a vertical market perspective, Enterprise and US Federal were significant contributors to the quarter's revenue gains. Within our geographical regions, the US, the UK and northern Europe all delivered solid year-over-year growth.

"As F5 continues to evolve and adapt our technology to the rapidly changing IT landscape, we believe our strategy, product roadmap, and ongoing investment in people will enable us to drive top-line growth. In the near term, we remain confident that the company can continue to deliver solid year-over-year growth as we adjust our organization and business model to exploit the growing market opportunity for our expanding solutions portfolio," Rivelo said.

For the quarter ending September 30, 2015, the company has set a revenue goal of $500 million to $510 million with a GAAP earnings target of $1.26 to $1.29 per diluted share and a non-GAAP earnings target of $1.72 to $1.75 per diluted share.

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 net income excluding stock-based compensation, amortization of purchased intangible assets and acquisition-related charges, net of taxes, which is a non-GAAP financial measure under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended. This measure consists of GAAP net income excluding, as applicable, stock-based compensation, amortization of purchased intangible assets and acquisition-related charges. 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. Stock-based compensation is a non-cash expense that F5 has accounted for since July 1, 2005 in accordance with the fair value recognition provisions of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718 Compensation-Stock Compensation ("FASB ASC Topic 718"). Amortization of intangible assets is a non-cash expense. Investors should note that the use of intangible assets contribute to revenues earned during the periods presented and will contribute to revenues in future periods. Acquisition-related expenses consist of professional services fees incurred in connection with acquisitions.

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 measure of earnings and earnings per share provides investors with an additional tool for evaluating the performance of the company's core business and which management uses 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 this supplemental measure since, with reconciliation to GAAP, it may provide additional insight into the company's operational performance and financial results.

For reconciliation of this non-GAAP financial measure to the most directly comparable GAAP financial measure, please see the section in our Consolidated Statements of Operations entitled "Non-GAAP Financial Measures."
