NEI ANNOUNCES FINANCIAL RESULTS FOR THE THIRD FISCAL QUARTER 2010

Revenue Increases 85% Compared to Q3 Fiscal 2009

Third Consecutive Quarter of GAAP Profitability

CANTON, Mass., July 29, 2010 — NEI (Nasdaq: NENG), a leading provider of server-based application platforms, appliances, and lifecycle support services for software developers and OEMs worldwide, today reported financial results for its third fiscal quarter, the period ended June 30, 2010.

Third Quarter Financial Performance

·Net revenues were a record $61.6 million, an increase of 12 percent compared sequentially to the $55.0 million in the second fiscal quarter and 85 percent compared to the $33.3 million for the third quarter of the prior fiscal year. The results were below the guidance of $64 to $69 million. The year-over-year increase was primarily due to increased volume from NEI’s two largest customers, while the sequential increase was mostly related to NEI’s largest customer.

·Gross profit margin was 11.0 percent of net revenues, within the guidance of 10.5 to 11.5 percent and compared sequentially to 11.8 percent in the second fiscal quarter and compared to 15.1 percent for the third fiscal quarter of the prior year.

·Operating expenses were $6.1 million, including $205,000 of stock-based compensation expense and $389,000 of amortization expense, and were within the guidance range of $6.1 million to $6.6 million. Operating expenses compared to $6.3 million in the year-ago third quarter, which included $285,000 of stock-based compensation expense and $439,000 of amortization expense.

·Net income on a GAAP basis was $672,000, or $0.01 per share, which included $243,000 of stock-based compensation expense and $389,000 of amortization expense. The results were within guidance of net income of $400,000 to $1.0 million. The net income on a GAAP basis compared to a net loss on a GAAP basis of $(1.2) million, or $(0.03) per share in the third fiscal quarter last year, which included $319,000 of stock-based compensation expense and $439,000 of amortization expense.

·Non-GAAP net income, which excludes stock-based compensation, amortization expenses and a tax benefit related to a Net Operating Loss (NOL) carryback, was $1.2 million, or $0.03 per share, within the expected range of non-GAAP profit between $1.0 million and $1.6 million. The non-GAAP net income compared to a non-GAAP net loss of $(485,000), or $(0.01) per share in the third fiscal quarter of 2009.

Greg Shortell, President and Chief Executive Officer of NEI, commented, “The third quarter revenue was a record for NEI, as we delivered an 85% year-over-year increase supported by contribution from design wins secured in the last year. However, customer product transitions, project delays and visibility related to certain customer programs resulted in lower revenues than the guidance we had issued last quarter. Even so, we are pleased with the double-digit year-over-year growth in this record quarter.”

Mr. Shortell continued, “In addition, our gross margin, operating expenses, and net income were all in-line with expectations and we are pleased to be reporting our third consecutive profitable quarter. We

continue to deliver solid fundamental execution and remain focused on growing revenue and controlling expenses. The large 2009 design win from our largest customer has been fully integrated, and we are working on prototypes for an additional project with them, as discussed last quarter. We expect this business to be incremental to our revenue, beginning in the next calendar year.”

During the first nine months of fiscal 2010, NEI added 18 new design wins, compared to 28 design wins last year. As a reminder, the Company now tracks design wins as only those with new customers, or with entirely disparate divisions within existing customers. EMC comprised 58 percent of total revenues during the quarter compared to 35 percent in the year ago quarter and Tektronix comprised 20 percent of net revenues during the quarter compared to 11 percent in the year-ago quarter.

Balance Sheet

NEI finished the quarter with $12.7 million in cash and cash equivalents and $48.7 million in working capital. Inventory and accounts receivable levels increased to $24.0 million and $35.7 million compared to $13.1 million and $27.5 million as of September 30, 2009, as the Company integrated the large 2009 design win from its largest customer. NEI also has a $10 million bank credit facility that it has yet to borrow from.

Business Outlook

NEI currently anticipates the following results for its fiscal fourth quarter ending September 30, 2010, based on current forecasts from certain customers and historical trends.

·Net revenues in the range of $55 million to $60 million.

·Gross profit margin in the range of 10.0 percent to 11.0 percent of net revenues.

·Operating expenses between $5.8 million and $6.4 million, including an estimated $205,000 of stock-based compensation expense and amortization expense of $389,000.

·Net income (loss) on a GAAP basis in the range of $(300,000) to $300,000.

·Net income on a non-GAAP basis in the range of $300,000 to $900,000.

“Our revenue visibility is based on forecasts from our customers and our lower guidance is primarily related to the project-oriented nature of our customers who service the telecommunications market segment and, to a lesser extent, what appears to be some summer seasonality,” stated Doug Bryant, Chief Financial Officer. “Even considering these factors, we are projecting a year-over-year revenue increase of at least 35 percent. Although we expect some choppiness in our revenues, we believe that we will continue to grow revenues and that we have the ability to leverage our existing infrastructure without significant incremental expenditures as annual revenues increase.”

Important Information about Non-GAAP References

References by NEI (the “Company”) to non-GAAP net income or loss and non-GAAP per share information refer to net income or loss or per share information excluding stock-based compensation expense, amortization expense and a one-time federal income tax benefit related to an NOL carryback. GAAP requires that these expenses and charges be included in determining net income or loss and per share information. The Company’s management uses non-GAAP operating expenses, and associated non-GAAP net income or loss (which is the basis for non-GAAP per share information) to make operational and investment decisions, and the Company believes that they are among several useful measures for an enhanced understanding of its operating results for a number of reasons.

First, although the Company undertakes analyses to ensure that its stock-based compensation grants are in line with peer companies and do not unduly dilute shareholders, the Company allocates grants and measures them at the corporate level. Second, management excludes their financial statement effect when planning or measuring the periodic financial performance of the Company’s functional organizations since they are episodic in nature and unrelated to its core operating metrics. Lastly, we believe that providing non-GAAP per share information affords investors a view of results that may be more easily compared to peer companies and enables investors to consider the Company’s results on both a GAAP and non-GAAP basis in periods when the Company is undertaking non-recurring activities.

The Company believes these non-GAAP measures will aid investors’ overall understanding of the Company’s results by providing a higher degree of transparency for certain expenses, and providing a level of disclosure that will help investors understand how the Company plans and measures its own business. However, non-GAAP net income or loss should be construed neither as an alternative to GAAP net income or loss or per share information as an indicator of our operating performance nor as a substitute for cash flow from operations as a measure of liquidity because the items excluded from the non-GAAP measures often have a material impact on the Company’s results of operations. Therefore, management uses, and investors should use, non-GAAP measures only in conjunction with the Company’s reported GAAP results.
