DSP Group Receives Growing Support from Stockholders, Customers and Suppliers Following Positive Recommendations from ISS, Glass Lewis and Egan Jones

SAN JOSE, Calif., June 5, 2013 — DSP Group^®, Inc. (NASDAQ: DSPG) a leading global provider of wireless chipset solutions for converged communications, issued today the following statement to its stockholders:

We are pleased to advise you that DSP Group has received growing support from its stockholders as well as endorsements from its customers and suppliers following the positive recommendations by ALL three proxy advisory services – ISS, Glass Lewis and Egan Jones – to REJECT Starboard’s entire slate and to vote the GOLD proxy card in favor of Company nominees.

Both Glass Lewis and Egan Jones recommend that stockholders vote the GOLD card for ALL of the Company’s nominees. ISS recommends stockholders vote the GOLD proxy card FOR the Company’s nominees Zvi Limon and Dr. Reuven Regev. DSP Group urges all of its stockholders to vote FOR all three highly-qualified and experienced director nominees – Eliyahu Ayalon, Zvi Limon and Dr. Reuven Regev. The loss of ANY incumbent director in favor of Starboard nominees would jeopardize the operational and financial gains that have been achieved and would result in a weaker and less experienced Board.

Our Largest Customer, VTech Telecommunications Ltd, and the World’s Leading Semiconductor Foundry, Our Supplier - Taiwan Semiconductor Manufacturing Company (TSMC), Have Signaled Their Support for DSP Group’s Current Management and Board:

“DSP Group has been at the forefront of the telecommunications market for over a decade. During this period DSP Group’s Board and management have demonstrated a strong commitment to and leadership of the telecommunication IC industry and have supported VTech with best-in-class products and fast time to market.” - C.H. Tong, President of VTech Telecommunications Limited

“TSMC has been cooperating with DSP Group for over a decade and has seen DSP Group grow to become one of our key customers. During this period DSP Group has demonstrated its deep understanding of its semiconductor market and is highly regarded for its technology innovation. The strong personal cooperation built between DSP Group’s management, its Board of Directors and TSMC’s management team has contributed to making DSP Group one of our closest partners.” - Maria Marced, President of TSMC Europe

Growing Stockholder Support in Proxy Contest

We are encouraged that following the recommendations of ISS, Glass Lewis and Egan Jones, the Board has received increasing indications of support from stockholders. We believe that the Company’s stockholders recognize that it is in their best interests to REJECT Starboard’s slate by voting the GOLD proxy card FOR ALL THREE Company’s nominees, and are focused on the following facts:

These Facts Were Recognized By All Three Independent Proxy Advisory Services – ISS, Glass Lewis and Egan Jones – As They Unanimously Recommended Stockholders Vote the GOLD proxy card, Thereby Rejecting Starboard’s Nominees:

ISS:

“As the dissidents have not made a compelling case that further change at the board level is necessary at this time, ISS recommends that shareholders vote on the GOLD proxy card and support the management nominees.”

Glass Lewis:

“All three of the Company’s nominees have a deeper understanding of DSP’s current situation, challenges and opportunities, as well as experience in the environment in which DSP operates. In our view, they are simply better qualified than the Dissident’s nominees to serve on the board of a fables (sic) semiconductor company such as DSP.”

Egan-Jones:

“…the dissidents have provided no specific plans and no substantive new ideas or valid reasons to change the Company’s strategic direction that will enhance the Company’s stockholder value…the Company has made strides and significant progress toward its goals to improve its operational and financial performance, including improved revenue efficiency, utilization and cash flow from operations”

Vote The GOLD Proxy Card Today

The 2013 Annual Meeting of DSP Group’s Stockholders is just a few days away, scheduled for Monday, June 10. We strongly recommend that stockholders vote the GOLD proxy card by telephone or internet today. Stockholders who have previously sent back a white proxy card sent to them by Starboard Value LP can still change their votes and support the DSP Group nominees by voting the GOLD proxy card today. Every vote is extremely important.
