DYNAMICS RESEARCH CORPORATION
REPORTS HIGHER REVENUES FOR SECOND QUARTER 2005
Increase of 17% year over year

Andover, Mass.—August 2, 2005—Dynamics Research Corporation (Nasdaq: DRCO) today reported revenues of $76.2 million and net income of $3.3 million, including $1.2 million of gain from the sale of stock, for the second quarter ended June 30, 2005. Earnings per diluted share were $0.36, including $0.13 attributable to the sale of stock, for the second quarter ended June 30, 2005. This compares with revenues of $65.0 million and net income of $2.2 million, or $0.24 per diluted share, for the same period in 2004.

Regarding performance for the quarter, James P. Regan, President, Chairman and CEO, said, “I am pleased that the operating results were consistent with our expectations, demonstrating further progress towards the achievement of our business objectives.”

“During the second quarter we received several strategically important contract awards that will fuel organic growth. Our pipeline is up sharply, our win rate is strong and the outlook remains positive,” Regan added.

Given the uncertainty of timing of awards under the recently awarded DESP II contract, DRC revised guidance for 2005. The company currently estimates revenues in the range of $312 to $318 million and earnings per diluted share in the range of $1.28 to $1.33 including the $0.13 per share impact of the sale of stock during the second quarter. For the third quarter of the year the company expects to book revenues in the range of $80 to $82 million and report earnings per diluted share of $0.31 to $0.33.

The company will conduct a conference call tomorrow, August 3, 2005 at 8:30 a.m. ET to discuss its second quarter results and the outlook for 2005 in more detail. The call will be available via telephone at (800) 946-0744, and accessible via Web cast at www.drc.com.
