ARUBA NETWORKS ANNOUNCES FISCAL FOURTH QUARTER AND FULL YEAR 2008 FINANCIAL RESULTS

Quarterly Revenues Increase by 13% Sequentially
Full Year Revenues Increase by 40%

SUNNYVALE, Calif., August 28, 2008 – Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in wireless LANs and secure unified mobility solutions, today released financial results for its fiscal fourth quarter and full year ended July 31, 2008.

Revenues for the fiscal fourth quarter of 2008 were $48.3 million, an increase of 16% from $41.7 million reported in the fiscal fourth quarter of 2007. GAAP net loss for the fiscal fourth quarter of 2008 was $6.8 million, or $0.08 per share, compared to a net loss of $3.4 million, or $0.04 per share, in the fiscal fourth quarter of 2007. GAAP results for the fiscal fourth quarter of 2008 included $5.7 million of non-cash stock-based expenses and $1.2 million of acquisition related expenses.

Non-GAAP net income for the fiscal fourth quarter of 2008 was $0.2 million, or $0.00 per share, compared to non-GAAP net income of $2.0 million, or $0.02 per share, in the fiscal fourth quarter of 2007. Non-GAAP net income excludes the impact of non-cash stock-based expenses in all periods, as well as acquisition related expenses in the fiscal fourth quarter of 2008 and expenses related to in-process research and development in the fiscal fourth quarter of 2007.

Revenues for the fiscal year ended July 31, 2008 were approximately $178.3 million, an increase of 40% from $127.5 million reported in the prior year. GAAP net loss for the full fiscal year 2008 was $17.1 million, or $0.22 per share, compared to a net loss of $24.4 million, or $0.70 per share in 2007. Non-GAAP net income for the full fiscal year was $4.0 million, or $0.04 per share, compared to a net loss of $2.0 million, or $0.06 per share in 2007.

“Wireless LAN technology is increasingly becoming an integral part of IT networks for a broad range of organizations and corporations,” said Dominic Orr, president and chief executive officer. “The strong sequential revenue growth in our fiscal fourth quarter was driven by increased demand from existing customers and a record number of new customer additions. During the period, we added over 700 new customers and now have over 5,000 cumulative customers. The quarter was notable for the strong performance of our education vertical and broad demand from a very wide range of other customers. Importantly, we have also won new contracts in our retail and government verticals, which gives us increased momentum in these challenging areas as we enter our new fiscal year.”

“Revenues increased by 13% on a sequential basis and total deferred revenue was up 18% over the same period,” said Steffan Tomlinson, Aruba’s chief financial officer. “Total operating expenses decreased as a percentage of revenues on sequential basis and non-GAAP gross margins remained strong at 68.7%, above our long-term target range. We ended the quarter with $101.7 million in cash and investments, representing a $3.9 million increase on a sequential basis. ”

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 our ability to react to trends and challenges in our business and the markets in which we operate; business and economic conditions and growth trends in the networking industry, our vertical markets and various geographic regions; changes in customer order patterns or customer mix; overall information technology spending; our ability to establish and maintain successful relationships with our distribution partners; our ability to compete in our industry; fluctuations in demand, sales cycles and prices for our products and services; rapid

All forward-looking statements in this press release are based on information available to us as of the date hereof, and we assume no obligation to update these forward-looking statements.

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, for the fiscal fourth quarter of 2008, acquisition-related expenses, and, for the fiscal fourth quarter of 2007, expenses related to in process research and development.  Aruba defines non-GAAP EPS as non-GAAP net income divided by the weighted average diluted shares outstanding.  Aruba’s management believes that these non-GAAP financial measures provide meaningful supplemental information regarding the company’s performance by excluding certain non-cash expenses.  Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FAS 123R, Aruba’s management believes that providing these non-GAAP financial measures 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 in process research and development and acquisition-related expenses, Aruba’s management believes that investors can better understand the impact of such expenses on the Company’s continuing 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, that are recurring.  Stock-based expenses 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.
