SAN JOSE, Calif., Feb. 24, 2011 (GLOBE NEWSWIRE) -- Endwave Corporation (Nasdaq:ENWV), a leading provider of high-frequency RF solutions and semiconductor products for the telecommunications, satellite communications, electronic instruments and defense and security markets, today reported financial results for its fourth quarter and full fiscal year, which ended on December 31, 2010.

Revenues for the fourth quarter of 2010 were $4.1 million. This compares with revenues of $4.1 million in the prior quarter and $3.6 million in the fourth quarter of fiscal 2009. Net loss, calculated in accordance with accounting principles generally accepted in the United States (GAAP), for the fourth quarter of 2010 was $2.0 million, or $0.20 per share. This compares with a net loss of $2.0 million, or $0.20 per share in the prior quarter, and a net loss of $3.4 million, or $0.36 per share, in the fourth quarter of fiscal 2009.

Non-GAAP Results

Non-GAAP net loss in the fourth quarter of 2010 was $2.0 million, or $0.21 per share. This compares with non-GAAP net loss of $1.8 million, or $0.18 per share, in the prior quarter and non-GAAP net loss of $2.0 million, or $0.21 per share, in the fourth quarter of fiscal 2009.

For the fourth quarter of 2010, non-GAAP net loss was calculated by excluding non-cash stock-based compensation expense of $50,000 and a reversal of certain non-cash stock-based compensation of $74,000. For the prior quarter, non-GAAP net loss was calculated by excluding non-cash stock-based compensation expense of $140,000 and restructuring expense of $63,000. For the year ago period, non-GAAP net loss was calculated by excluding certain restructuring charges of $1.2 million, inventory reserves and bad debt expense due to a customer liquidation of $191,000 and non-cash stock-based compensation expense of $32,000.

Cash, cash equivalents and investments as of December 31, 2010 were $23.5 million, compared with $24.7 million as of September 30, 2010. 

"During Q4 we saw decreasing demand for our legacy products, however that was counter-balanced by demand for new products that are utilized in next generation, high capacity, IP-based radios. While we are seeing continuing progress in the market acceptance of our microwave and millimeter wave integrated circuit product line, revenues are still modest as we go through the lengthy sales, design, qualification and production ramp cycles with our customers," said John Mikulsky, Endwave's President and Chief Executive Officer. "Using our years of experience in the microwave radio market as a basis, we are also expanding our marketing activities into adjacent markets in order to develop new revenue streams."

Full Year 2010 Results

For the full year, revenues were $16.7 million, compared with $19.5 million for 2009.

GAAP net loss for the year ended December 31, 2010 was $8.1 million, or $0.83 per share compared with GAAP net income for 2009 of $6.9 million, or $0.73 per share. Non-GAAP net loss for the year ended December 31, 2010 was $7.7 million, or $0.78 per share, compared with a non-GAAP net loss for the year ended December 31, 2009 of $6.0 million, or $0.63 per share. For 2010, non-GAAP net loss was calculated by excluding non-cash stock-based compensation expense of $386,000 and certain restructuring charges of $49,000. For 2009, non-GAAP net loss was calculated by excluding income from discontinued operations of $17.6 million, net of taxes, certain restructuring charges of $2.4 million, non-cash stock-based compensation expense of $2.0 million, and inventory reserves and bad debt expense due to a customer liquidation of $191,000.

Announced Merger with GigOptix

"On February 7, we announced our merger agreement with GigOptix.    We believe that when the transaction closes, the combined company will be well-positioned to become a high speed, high frequency leader for optical and wireless communications," said Mikulsky. "We anticipate this transaction will bring added value to our customers and stockholders by capitalizing on the increasing network bandwidth demands and leveraging our combined product portfolios in high speed fiber and wireless communications."

The transaction is expected to close in the second quarter of 2011, and the combined company will retain the name GigOptix, Inc.

Restructuring Activity

In order to reduce operating expenses, the company currently expects to restructure its organization by reducing its workforce by an estimated 14 employees, or 27 percent, in March and closing its facilities both in Salem, New Hampshire and Folsom, California by the end of April. It anticipates annualized savings of approximately $1.2 million from these actions. The company will incur cash charges of approximately $700,000 related to the restructuring, plus a non-cash restructuring charge related to the acceleration of certain stock awards for the affected personnel.

"Over the past several years, we have been diligent at reducing our expenses to better align them with our revenue projections.   This action is a continuation of those efforts," said Curt Sacks, Endwave's Senior Vice President and Chief Financial Officer. "We continue to maintain our investment in key R&D functions and believe that these restructuring activities will not impact our core operations."
