Ofer Elyakim, CEO of DSP Group, stated: “Despite the overhang and depletion of excess inventory at several ODM and OEM customers during the fourth quarter, we were able to execute and deliver on our 2010 business plan as reflected in the year-on-year improvements in all of our annual financial metrics. In addition, we generated $17 million of free cash flow during the year and ended the year with a strong cash position of approximately $140 million in cash and cash equivalents.”

Mr. Elyakim also added: “The Consumer Electronics Show in January displayed a number of new products which will be based on DSP Group platforms. We expect that these new products based on our XpandR, CAT iq and VOIP platforms will be commercially launched during the course of the year, with more product launches expected in the second half of the year. As we look to 2011, we expect conditions in our markets to improve and based on forecasts and prospects received from customers, we project annual revenues in the range of $227 million to $245 million, representing approximately an increase of 5% in revenues in 2011 as compared to 2010.”

The Company believes that the non-GAAP presentation of net income, loss per share and diluted EPS presented in this press release is useful to investors in comparing results for the quarter and year ended December 31, 2010 to the same periods in 2009 because the exclusion of the above noted expenses may provide a more meaningful analysis of the Company’s core operating results. Further, the Company believes it is useful to investors to understand how the expenses associated with equity-based compensations expenses are reflected on its statements of income.

Forward-Looking Statements

This press release contains statements that qualify as “forward-looking statements” under the Private Securities Litigation Reform Act of 1995, including Mr. Elyakim’s statements about commercial launches of products based on DSP Group technology in 2011, improvements in market conditions in 2011 and annual revenue guidance for 2011. These forward-looking statements are based on current expectations and DSP Group assumes no obligation to update this information. In addition, the events described in these forward-looking statements may not actually arise as a result of various factors, including the impact of reductions in lead times and inventory levels by DSP Group customers and their customers; assumption that excess inventory would be completely depleted by the end of the first quarter of 2011; unexpected delays in the introduction of new products, especially the new generation of multimedia products; the sustainability of the market recovery; fluctuations in gross margins associated with the sale of existing products; slower than expected change in the nature of residential communications domain; DSP Group’s inability to develop and produce new products at competitive costs and in a timely manner or failure of such products to achieve broad market acceptance; and general market demand for products that incorporate DSP Group’s technology in the market. These factors and other factors which may affect future operating results or DSP Group’s stock price are discussed under “RISK FACTORS” in the Form 10-K for fiscal 2009 as well as other reports DSP Group has filed with the Securities and Exchange Commission and which are available on DSP Group’s Web site (www.dspg.com) under Investor Relations.
