WITH RECENT TRANSACTION

Atlanta, Georgia — September 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 the guarantees and associated notes payable of $711,000 related to its acquisition of RS Staffing Services have been satisfied through a combination of the repurchase of certain of the shares of the Company’s common stock owned by one of the note holders and the expiration of the guarantee period under the Company’s July 22, 2011 settlement agreement with these note holders.  Following the completion of the sale of additional DLH shares by this holder to members of DLH’s management team, the Company’s remaining liability under the guarantee was further reduced.  As a result of this transaction and the payment by DLH of $225,000, DLH has now fully satisfied its minimum guarantee obligations related to the notes and will, therefore, record a gain of approximately $486,000 in the fiscal fourth quarter ending September 30, 2012.
