Exhibit 99.1

DYNAMICS RESEARCH CORPORATION
REPORTS FIRST QUARTER 2007 RESULTS

Andover, Mass.—May 2, 2007—Dynamics Research Corporation (Nasdaq: DRCO), a leading provider of innovative engineering, technical and information technology services and solutions to federal and state governments today announced operating results for the first quarter ended March 31, 2007.

Financial Results

The Company reported revenue of $56.8 million for the first quarter of 2007, compared with $68.2 million for the same period in 2006. Completion of the Company’s Air National Guard contract in May 2006 and lower subcontractor revenue resulting from the recent, successful transition to the USAF Consolidated Acquisition and Professional Services (CAPS) contract accounted for $9.5 million of the change in revenues for the first quarter of this year, compared with a year ago. Net income was $1.1 million, or $0.12 per diluted share, for the first quarter of 2007 compared with $1.4 million, or $0.15 per diluted share, before the effect of an accounting change for the same period a year ago.

Business Highlights

“Our financial results for the first quarter of 2007 were solid with several key indicators trending favorably,” said Jim Regan, DRC’s chairman and chief executive officer. “Revenues exceeded our expectations, with a substantial increase in revenues derived from billable hours compared with the fourth quarter of last year, while subcontractor revenues related to the successful transition to the CAPS contract decreased by $4.5 million on a sequential basis. Operating margin of 4.3% for the quarter just ended also was seasonally strong, comparing favorably with 4.1% for the same period in 2006.

“While Federal budgetary pressures have continued to delay contract awards we are having success growing our business base utilizing a number of important contracts we have won over the past year. Looking ahead, we anticipate a pick-up in contract award announcements as the year progresses,” Regan added. The Company also received in the first quarter of 2007 new business contract awards having an estimated total value of $62 million.

Company Guidance

The Company estimates revenues for the calendar year 2007 to be in the range of $225 to $240 million and earnings per diluted share to be in the range of $0.65 to $0.75, unchanged from the Company’ previous guidance. For the second quarter of 2007 the Company anticipates revenues in the range of $56 to $58 million and earnings per diluted share of $0.14 to $0.16.
