NETEZZA ANNOUNCES FIRST QUARTER
FISCAL YEAR 2011 FINANCIAL RESULTS

Marlborough, MA — May 25, 2010 —Netezza Corporation (NYSE: NZ), the global leader indata warehouse, analytic and monitoring appliances, today reported its financial results for the first fiscal quarter ended April 30, 2010.

“Our first quarter was an outstanding quarter for Netezza,” said Jim Baum, Netezza’s President and Chief Executive Officer. “Our revenue growth in the quarter demonstrates the widespread adoption of our TwinFin™ family of appliances. This, together with our recently introduced Skimmer™ and i-Class™ products, will continue to broaden our market reach and opportunity.”

Total revenue for the first quarter of fiscal 2011 (fiscal year ending January 31, 2011) increased 28 percent to $58.2 million compared to $45.4 million for the first quarter of fiscal 2010. GAAP net income for the first quarter of fiscal 2011 was $2.7 million, or $0.04 per diluted share, compared to GAAP net loss of $0.2 million, or $0.00 per diluted share, for the first quarter of fiscal 2010. Non-GAAP net income for the first quarter of fiscal 2011 was $4.9 million, or $0.08 per diluted share, compared to non-GAAP net income of $1.6 million, or $0.03 per diluted share, for the first quarter of fiscal 2010.

Non-GAAP net income and non-GAAP net income per diluted share exclude non-cash stock-based compensation, amortization of acquired intangible assets and the related income tax effect of excluding these expenses. A reconciliation of GAAP to non-GAAP results has been provided in the financial statements included in this press release. An explanation of these measures is also included below under the heading “Use of Non-GAAP Financial Measures.”

Financial Commentary

“Our first quarter was a great quarter and more importantly a positive indicator for our business as a whole,” said Patrick Scannell, Netezza’s Senior Vice President and Chief Financial Officer. “We saw our pipeline expand across the board with our visibility remaining strong. As a result, we are increasingly confident with our previously issued 20% annual revenue growth guidance and we expect year over year operating margin improvement.”

The statements set forth in this press release include forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements relate to Netezza’s future financial performance and Netezza’s business prospects. These statements involve risk and uncertainties, including, among others: market demand for and acceptance of our products; adverse changes in economic conditions; quarterly fluctuation of our business; our limited operating history and history of losses; our dependence on a single product family for nearly all of our revenue; our ability to attract and retain key personnel; our ability to develop and introduce new products and manage product transitions; competition in the data warehouse market; our dependence on certain key customers; our ability to protect our patents and intellectual property; our ability to defend against third party infringement claims, other litigation and contingent liabilities; and risks relating to operating internationally. For a further list and description of risks and uncertainties that could cause actual results to differ materially from those contained in the forward-looking statements in this release, we refer you to the “Risk Factors” sections of Netezza’s Annual Report on Form 10-K for the year ended January 31, 2010 which is on file with the SEC and available in the investor relations section of Netezza’s Web site athttp://www.netezza.com and on the SEC Web site athttp://www.sec.gov. In addition, any forward-looking statements included in this press release represent our views as of May 25, 2010. We anticipate that subsequent events and developments will cause our views to change.

Use of Non-GAAP Financial Measures

To supplement Netezza’s unaudited condensed consolidated financial statements presented in accordance with GAAP, Netezza is presenting certain non-GAAP measures of financial performance. Netezza believes that these non-GAAP financial measures, when taken together with the corresponding

GAAP financial measures, provide meaningful supplemental information regarding Netezza’s performance by excluding certain non-cash items that may not be indicative of Netezza’s core business or future outlook. The presentation of these non-GAAP measures is not intended to be considered in isolation from, as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Netezza’s results of operations as determined in accordance with GAAP.

The non-GAAP financial measures presented by Netezza exclude non-cash stock-based compensation, amortization of acquired intangible assets and the related income tax effect of excluding these expenses. Because of the varying valuation methodologies and assumptions that companies use to measure stock-based compensation expense, Netezza’s management believes that excluding non-cash stock-based compensation allows investors to analyze Netezza’s recurring business over multiple periods and provide more meaningful comparisons with other companies. Because the amount of amortization of acquired intangible assets varies in amount and frequency and is significantly affected by the timing and size of our acquisitions, Netezza’s management believes that excluding amortization of acquired intangible assets allows investors to analyze Netezza’s recurring business over multiple periods. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures provided in the financial statements included in this press release.
