Netezza Announces First Quarter Fiscal 2009 Financial Results

Netezza Corporation (NYSE Arca: NZ), the global leader in data warehouse and analytic appliances, today reported its financial results for the first fiscal quarter ended April 30, 2008.

Jit Saxena, Netezza´s Chairman and Chief Executive Officer, stated, "We continue to be pleased with the results of our business on all fronts. Our customers, both new and existing, are deploying the Netezza appliance across a wide array of vertical markets. This continued strength and momentum in our business validates the investments that we are making in product development and channels to address our customer needs and the market opportunity in front of us."

Total revenue for the first quarter of fiscal 2009 (fiscal year ending January 31, 2009) increased 56% to $39.6 million compared with $25.3 million for the same period one year ago. GAAP net income attributable to common stockholders for the first quarter of fiscal 2009 was $2.1 million compared with a GAAP net loss attributable to common stockholders of $3.4 million for the same period one year ago. Non–GAAP net income attributable to common stockholders for the first quarter of fiscal 2009 was $3.8 million compared with a non–GAAP net loss attributable to common stockholders of $1.0 million for the same period one year ago. GAAP diluted net income per share for the first quarter of fiscal 2009 was $0.03 compared with a GAAP diluted net loss per share of $0.44 for the same period one year ago. Non–GAAP diluted net income per share for the first quarter of fiscal 2009 was $0.06 compared with a non–GAAP diluted net loss per share of $0.13 for the same period one year ago.

Non–GAAP net income (loss) attributable to common stockholders, non–GAAP diluted net income per share and non–GAAP operating income exclude non–cash stock–based compensation and, where applicable, accretion of preferred stock dividends. 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 Guidance:

"Based upon the continued deployment of our solutions in the marketplace on a global basis, we are raising our revenue guidance from $165 – $168 million to the $172 million level for fiscal year 2009," said Patrick Scannell, Senior Vice President and Chief Financial Officer of Netezza. "We are continuing to invest in all disciplines and maintain our guidance of targeting non–GAAP operating income of 7–9% of revenue and GAAP operating income of 1–2% of revenue for the fiscal year."

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 and, where applicable, accretion of preferred stock dividends. Because of the varying valuation methodologies and assumptions that companies use under FAS123(R), 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 comparison with other companies. Upon the closing of Netezza´s initial public offering, accretion of preferred dividends was no longer applicable due to the conversion of preferred stock to common stock, and is therefore excluded to aid in comparing current and future operating results with those of past 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.
