NEI ANNOUNCES LARGEST CUSTOMER’S PLAN TO DUAL SOURCE SPECIFIC PRODUCT LINE

No Impact on Current Quarter Guidance; Dual Sourcing Expected to Commence in September 2011 Quarter

CANTON, Mass., May 19, 2011 — NEI (Nasdaq: NEI), a leading provider of server-based application platforms, deployment solutions and lifecycle support services for software technology developers and OEMs worldwide, today announced that it has been notified by EMC that, as part of a strategic initiative, the integration of EMC’s Avamar product line will be dual sourced beginning in the quarter ending September 30, 2011.  Although this does not impact the financial guidance that NEI provided on April 28, 2011 for the quarter ending June 30, 2011, it will impact financial results beginning in the quarter ending September 30, 2011.  Based on the current customer forecast and estimates, the impact of this change is expected to be a $5 million to $7 million reduction in this program’s revenues to NEI and a $500,000 to $700,000 reduction in Net Income for the quarter ending September 30, 2011.  The Company expects the impact on future quarters, beginning in the quarter ending December 31, 2011, to be a $9 million to $11 million reduction in this program’s quarterly revenues to NEI and a $900,000 to $1.1 million reduction in Net Income.  NEI expects to remain profitable.

Greg Shortell, President and Chief Executive Officer of NEI, commented, “we are naturally disappointed at the revenue reduction and bottom line impact of this particular program being dual sourced.  However, we’ve been informed that this decision is not performance-related and we believe that NEI will have the opportunity to participate in additional EMC programs as a proven, trusted supplier to EMC.”
