Ofer Elyakim, CEO of DSP Group, stated “Our business results for the first quarter were consistent with our financial projections. Furthermore, we believe that the inventory correction that impacted our results in both the fourth quarter of 2010 and first quarter of 2011 is finally behind us. We anticipate solid demand going forward and expect our second quarter revenues to grow by approximately 20% compared to the first quarter of 2011.” Mr. Elyakim also stated, “We are happy to announce that two leading telecommunication operators in Western Europe chose to integrate our DECT CAT-iq products in their new line of residential gateways with commercial shipments of such products having taken place already in the first quarter.”

The Company believes that the non-GAAP presentation of net income and diluted EPS presented in this press release is useful to investors in comparing results for the quarter ended March 31, 2011 to the same period in 2010 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 the conclusion of the inventory correction, as well as the Company’s expectation that second quarter revenues will grow by approximately 20% as compared to the first quarter of 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 timing and ability of the market to recover and the corresponding recovery of DSP Group’s customers; the impact of reductions in lead times and inventory levels by DSP Group customers and their customers; unexpected delays in the introduction of new products; especially the new generation of multimedia products; 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 2010 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.
