Atlanta, Georgia — November 27, 2012 — DLH Holdings Corp. (NASDAQ: DLHC), a leading healthcare and logistics services provider to the Federal Government, including the Departments of Defense and Veterans Affairs, announced today that it has appointed Mr. Austin Yerks, a senior executive in the federal marketplace with over 30 years of experience, to its Board of Directors. Mr. Yerks was appointed as a Class 2 Director with an initial term expiring at the Company’s next annual meeting of stockholders to be held in 2013.

Mr. Yerks comes to DLH from a distinguished career as the President of CSC’s North American Public Sector — Defense and Intelligence Group with sales in excess of $3 billion in revenue annually and over 13,000 employees. Prior to that, he served as President of CSC’s Federal Business Development organization that was responsible for all business development and strategic marketing oversight for the operational business units of CSC Federal Sector.

Chairman of the Board, Mr. Rick Wasserman commented: “We are very fortunate to have Austin join our board. His extensive and diverse federal and defense experience will bring a wealth of knowledge as we continue to pursue the strategic initiatives developed by the executive management team.”

President and Chief Executive Officer, Zachary Parker added, “Mr. Yerks is widely respected within the defense community and other federal agencies. His insight and expertise will be invaluable to DLH, particularly in our efforts to substantially enhance DLH shareholder value.  In many ways, CSC is a “benchmark” company given DLH’s strategic path and Mr. Yerks’ experience makes him uniquely-qualified to provide oversight and guidance to our management team as we look to the future.”
