FOR IMMEDIATE RELEASE

MERU NETWORKS PROVIDES PRELIMINARY FIRST QUARTER 2011 FINANCIAL RESULTS

SUNNYVALE, Calif., April 4, 2011 – Meru Networks, Inc., (NASDAQ:MERU), the leader in 802.11n virtualized wireless LAN solutions for enterprise networking, today provided preliminary unaudited financial results for its first quarter ended March 31, 2011.

Based on preliminary financial information, Meru Networks expects to report first quarter revenue in the range of $20.0 million to $20.5 million. The company had previously provided revenue guidance in the range of $21.5 million to $22.5 million. First quarter non-GAAP operating expenses, which excludes the impact of stock based compensation expenses of approximately $1.3 million, are expected to be in the range of $14.7 million to $14.8 million, compared to prior guidance of approximately $14.8 million.

“In the first quarter we saw a number of transactions, primarily in the United States, that we anticipated would close but with the quarter concluded, it is now apparent that these transactions are experiencing longer than expected approval processes,” said Ihab Abu-Hakima, president and chief executive officer of Meru Networks. “This included a lengthening of the budget approval process for a number of our domestic education customers. We continue to believe there is a healthy market for wireless LAN solutions, and accordingly during the first quarter we increased our investment in our sales teams and channel partners to capitalize on this opportunity. We plan to continue increasing our investment in sales coverage and capacity, and expect to announce a new head of worldwide sales in the coming weeks.”

Non-GAAP Financial Measurements

In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, Meru reports non-GAAP net income (loss), which excludes stock-based compensation expense and adjustments to the fair value of the warrant liability. Meru believes that its non-GAAP net income (loss) provides useful information to management and investors regarding financial and business trends relating to its financial condition and results of operations. Meru also believes the non-GAAP measures provide useful supplemental information for investors to evaluate its operating results in the same manner as the research analysts that follow Meru, all of whom will present non-GAAP projections in their published reports. As such, the non-GAAP measures provided by Meru facilitate a more direct comparison of its performance with the financial projections published by the analysts as well as its competitors, many of whom report financial results on a non-GAAP basis. The economic substance behind its decision to use such non-GAAP measures is that such measures approximate its controllable operating performance more closely than the most directly comparable GAAP financial measures. For example, Meru’s management has no control over certain variables that have a major influence in the determination of stock-based compensation such as the volatility of its stock price and changing interest rates. Meru believes that all of these excluded expenses and income do not accurately reflect the underlying performance of its continuing operations for the period in which they are incurred, even though these excluded items may be incurred and reflected in Meru’s GAAP financial results.

The material limitation associated with the use of non-GAAP financial measures is that the non-GAAP measures do not reflect the full economic impact of Meru’s activities. Meru’s non-GAAP measures may be calculated differently than non-GAAP financial information disclosed by other companies. Accordingly, investors are cautioned not to place undue reliance on non-GAAP information.
