Business Overview	Business Overview For more than 25 years, DLH Holdings Corp. ("DLH"), has provided professional services to the U.S. Government. Headquartered in Atlanta, Georgia, DLH employs over 1,250 skilled healthcare and support personnel, technicians, logisticians, and engineers at more than 30 locations around the United States. DLH’s operating subsidiary, DLH Solutions, Inc., is organized into two major market areas: Healthcare Delivery Solutions and Medical Logistics & Technical Services. Our government customers, a majority of whom are within the Departments of Veterans Affairs (“DVA”) and Defense (“DoD”), benefit from our proven leadership, processes, technical excellence, industry-leading productivity and affordability enhancement tools, and Lean Six Sigma-based quality improvement processes.

DLH remains dependent upon the continuation of its relationship with the DVA. As of March 31, 2016, awards from the DVA have anticipated periods of performance ranging from approximately one to up to three years. These agreements are subject to the Federal Acquisition Regulations. While there can be no assurance as to the actual amount of services that the Company will ultimately provide to the DVA under its current contracts, we believe that our strong working relationship and our effective service delivery support ongoing performance for the contract term. The Company's results of operations, cash flows and financial condition would be materially adversely affected in the event that we were unable to continue our relationship with the DVA.
