SAN JOSE, Calif., July 26, 2011 - DSP Group®, Inc. (NASDAQ: DSPG), a leading global provider of wireless chipset solutions for converged communications at home, announced today its results for the second quarter ended June 30, 2011.

Second Quarter Results:

Revenues for the second quarter of 2011 were $58,517,000, a decrease of 4% from revenues of $60,846,000 for the second quarter of 2010. Net loss for the second quarter of 2011 was $2,041,000, as compared to net loss of $367,000 for the second quarter of 2010. Earnings per share (EPS) for the second quarter of 2011 were a loss of $0.09 per share, as compared to a loss of $0.02 per share for the second quarter of 2010.

Non-GAAP Results:

Non-GAAP net income and diluted EPS for the second quarter of 2011 were $2,030,000 and $0.08 per share, respectively, as compared to non-GAAP net income of $4,354,000 and non-GAAP diluted EPS of $0.18 per share for the second quarter of 2010. Non-GAAP net income and diluted EPS for the second quarter of 2011 excluded the impact of amortization of acquired intangible assets of $2,198,000 associated with the acquisition of NXP’s CIPT business and equity-based compensation expenses of $1,873,000. Non-GAAP net income and diluted EPS for the second quarter of 2010 excluded the impact of amortization of acquired intangible assets of $2,488,000 associated with the acquisition of NXP’s CIPT business and equity-based compensation expenses of $2,233,000.

Ofer Elyakim, CEO of DSP Group, stated: “We met our financial projections for the second quarter, including revenues of approximately $59 million, which represented a growth rate of 20% on a sequential basis; non-GAAP net income of $2 million which resulted in non-GAAP earnings per share of $0.08; and maintained a stable cash balance of $137 million. We are now focused on meeting the challenges we are facing in our markets in the second half of 2011. In the past few weeks we have experienced a slowdown in bookings, due to what appears to be a near-term softening of the consumer electronics market, resulting

1

in weaker demand for cordless telephony products. As a result of these macro-economic conditions, we are experiencing a decrease in customer projections. Accordingly, we are updating our revenue guidance for the year to be in the range of $200 million to $207 million, down from $227 million to $245 million. In response to these short-term market trends, we have decided to take proactive measures and implement further cost synergies in the second half of 2011, to reduce operating expenses and maintain positive operating cash flows.”

Mr. Elyakim also stated, “Despite our lower revenue guidance for the year as a result of this near-term, temporary market slowdown, we are seeing strong evidence that our past R&D investments in new product areas are gaining significant market traction and delivering revenue growth that we expect to accelerate over the long-term. For 2011, we expect new products revenue of approximately $25 million, representing a 56% increase over 2010.”

Authorization of Stock Repurchases

The Company’s Board has unanimously authorized a 1 million share increase in the number of shares of Common Stock the Corporation is authorized to repurchase pursuant to its stock repurchase plan, bringing the total authorization to 2.6 million shares.

Adoption of Rights Plan

The Company’s Board has unanimously adopted a Rights Agreement. Under the Rights Agreement, each stockholder of record on August 5, 2011, will receive a right for each share owned to purchase one-thousandth of a share of Series B Junior Participating Preferred Stock for $45. The rights will become exercisable should a person or group obtain beneficial ownership of 10% or more of the Company’s outstanding common stock, which acquiring person or group will not be able to exercise their rights. The Rights Agreement is scheduled to expire on July 25, 2012.

Presentation on non-GAAP Net Income Calculation

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 June 30, 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.
