F5 Networks Announces Results for First Quarter of Fiscal 2013

SEATTLE, JANUARY 23, 2013

For the first quarter of fiscal 2013, F5 Networks, Inc. (NASDAQ: FFIV) announced revenue of $365.5 million, up 1 percent from $362.6 million in the prior quarter and 13 percent from $322.4 million in the first quarter of fiscal 2012.

GAAP net income was $69.5 million ($0.88 per diluted share), compared to $67.7 million ($0.85 per diluted share) in the prior quarter and $66.5 million ($0.83 per diluted share) in the first quarter a year ago.

Excluding the impact of stock-based compensation and amortization of purchased intangible assets, non-GAAP net income was $90.6 million ($1.14 per diluted share), compared to $88.7 million ($1.12 per diluted share) in the prior quarter and $82.2 million ($1.03 per diluted share) in the first quarter of last year.

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

"During the first quarter, strong sales to North American enterprises and service providers were offset by a substantial slowdown in U.S. Federal sales," said John McAdam, F5 president and chief executive officer. "Japan sales were also weak during the quarter, in contrast to continuing strength in Europe and solid year-over-year growth in the rest of the Asia-Pacific region.

"A key driver of product revenue in the quarter was strong demand for BIG-IP 4200v, the first in our series of new ADC appliances, which we introduced in mid-October. Recently, we began shipping our new entry-level appliances, the 2000 series, which will be announced during the next few weeks along with our new high-end appliance, BIG-IP 10200, and our 8-blade VIPRION 4800 chassis.

"During the quarter, sales of our software modules and virtual edition (VE) products continued to gain traction. Very shortly, we will be announcing general availability of our Advanced Firewall Manager (AFM), as well as enhanced versions of Application Security Manager (ASM) and Access Policy Manager (APM), key components of our Application Delivery Firewall solution. In addition we will be launching new high-performance versions of all our BIG-IP VE products.

"As these and other new products enter the market over the next two quarters, we believe they will have a positive impact on our product revenue and continue to expand our addressable market," McAdam said.

F5 added 95 employees during the quarter and achieved a non-GAAP operating margin of 37.4 percent. The company also continued to strengthen its financial position, generating $145 million in cash from operations. After repurchasing 555,243 shares of outstanding common stock the company ended the quarter with $1.29 billion in cash and investments.

For the current quarter, ending March 31, management has set a revenue goal of $370 million to $380 million with a GAAP earnings target of $0.93 to $0.96 per diluted share and a non-GAAP earnings target of $1.21 to $1.24 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 Condensed Consolidated Statement of Operations entitled "GAAP to Non-GAAP Reconciliation."
