Ofer Elyakim, CEO of DSP Group, stated: “Our fourth quarter results were better than previously expected ending what has been a challanging year for DSP Group on a positive note. Looking forward, we are more optimistic about our 2012 outlook as channel inventory depletion cycle appears to be behind us.”

Mr. Elyakim continued: “Our revenue forecast for the full year is in the range of $200 to $220 million, representing an annual growth rate of approximately 8% at the mid point, fueled by significant growth from a promising pipeline of design wins from new market verticals such as home, business and mobile, as well as key design wins in cordless telephony.”

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 Company’s cautious optimistim about its 2012 outlook, completion of channel inventory depletion cycle, optimism for design wins and revenues to be generated from products for new market verticals in 2012 and annual 2012 revenue guidance. 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 our customers and their customers; continued uncertainty in consumer demand for traditional cordless telephony products in our major end markets, namely Europe and the US; the growth of new market verticals, namely home connectivity, IP telephony and mobile connectivity markets, that incorporate our XpandR, IP telephony and CAT-iq products; our ability to lower operating expenses; our ability to secure additional design wins; unexpected delays in commercial launch or mass production of new products incorporating our technologies; our ability to develop and produce new products at competitive costs and in a timely manner and for such products to achieve broad market acceptance; and general market demand for products that incorporate our technologies in the market.
