SUNNYVALE, Calif., February 17, 2011 — Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in distributed enterprise network solutions, today released financial results for its fiscal 2011 second quarter ended January 31, 2011.

Revenues for Q2’11 were $93.9 million, an increase of 50% from the $62.7 million reported in Q2’10. GAAP net loss for Q2’11 was $2.8 million, or $0.03 per share, compared to a net loss of $4.4 million, or $0.05 per share, in Q2’10.

Non-GAAP net income for Q2’11 was $16.3 million, or $0.14 per share. This compares to $6.3 million or $0.06 per share in Q2’10. A reconciliation between GAAP and non-GAAP information is contained in the tables below.

“We continue to see broad demand for our mobility solutions across all major geographies, as evidenced by our record revenues, 50% year-over-year growth and 13% sequential growth,” said Dominic Orr, President and Chief Executive Officer of Aruba. “Enterprises are facing intensified proliferation of tablet and smartphone devices, and IT’s ability to rapidly and affordably deliver secure mobile access for these devices is critical. This requires a user-, device- and application-centric approach to the network edge. We believe that the enterprise network is transitioning from a wired centric to a mobility centric architecture and the market is recognizing Aruba’s unique ability to address the requirements of this new architecture. During the quarter, we saw robust growth from the general enterprise and our core verticals, an increase in the number of larger potential deals in the pipeline, and the addition of a record 1,000+ new customers.”

“We had another strong quarter with record revenues and quarter over quarter and year over year gains in gross margins” said Steffan Tomlinson, Aruba’s Chief Financial Officer. During the quarter, we generated cash flow from operations of $10.7 million and ended the period with $187.8 million in cash.”

These forward-looking statements involve risks and uncertainties, as well as assumptions which, if they do not fully materialize or prove incorrect, could cause Aruba’s results to differ materially from those expressed or implied by such forward-looking statements. The risks and uncertainties that could cause our results to differ materially from those expressed or implied by such forward-looking statements include: (1) our ability to react to trends and challenges in our business and the markets in which we operate; (2) business and economic conditions and growth trends in the networking industry, our vertical markets and various geographic regions; and (3) changes in overall information technology spending; as well as those risks and uncertainties included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in Aruba’s report on Form 10-Q for the fiscal first quarter ended October, 2010, which was filed with the SEC on December 10, 2010, and is available on Aruba’s investor relations Web site at www.arubanetworks.com and on the SEC Web site at www.sec.gov.

Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with Generally Accepted Accounting Principles (GAAP), this press release and the accompanying tables contain the following non-GAAP financial measures: non-GAAP net income and non-GAAP earnings per share (EPS). The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

Non-GAAP net income and EPS. Aruba defines non-GAAP net income as net income plus stock-based expenses and related payroll taxes, amortization expense of acquired intangible assets and other acquisition related expenses, the change in the valuation of the contingent rights liability and litigation reserves. Aruba defines non-GAAP EPS as non-GAAP net income divided by the weighted average diluted shares outstanding. Aruba’s management regularly uses these non-GAAP financial measures to understand and manage its business and believes that these non-GAAP financial measures provide meaningful supplemental information regarding the company’s performance by excluding certain expenses that may not be indicative of Aruba’s “recurring operating results,” meaning its operating performance excluding not only stock-based expenses and related payroll taxes, but also discrete charges that are infrequent in nature, such as litigation reserves. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use, Aruba’s management believes that providing non-GAAP financial measures that exclude stock-based expenses allows investors to compare these results with those of other companies, as well as providing management with an important tool for financial and operational decision making and for evaluating the company’s operating results over different periods of time. Similarly, by excluding amortization expense of acquired intangible assets and other acquisition related expenses, the change in the valuation of the contingent rights liability and litigation reserves, Aruba’s management believes that investors can better understand and measure the company’s recurring operating results.

There are a number of limitations related to the use of non-GAAP net income and EPS versus net income and EPS calculated in accordance with GAAP. First, these non-GAAP financial measures exclude some costs, namely stock-based expenses and related payroll taxes, that are recurring. Stock-based expenses and related payroll taxes have been and will continue to be for the foreseeable future a significant recurring expense in Aruba’s business. Second, stock-based awards are an important part of Aruba’s employees’ compensation and impacts their performance. Third, the components of the costs that Aruba excludes in its calculation of non-GAAP net income may differ from the components that its peer companies exclude when they report their results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures and evaluating these non-GAAP financial measures together with their most directly comparable financial measures calculated in accordance with GAAP. The accompanying tables have more details on these non-GAAP financial measures, including reconciliations between these financial measures and their most directly comparable GAAP equivalents.
