Andover, Mass. — November 1, 2005 — Dynamics Research Corporation (Nasdaq: DRCO), a provider of innovative engineering, technical and information technology services and solutions to federal and state governments today announced operating results for the third quarter ended September 30, 2005.

Financial Results

Revenue for the third quarter of 2005 was $79.1 million, up $8.7 million or 12%, compared with $70.5 million for the same period a year ago. Revenue for the nine months ended September 30, 2005 was $228.8 million, up $31.4 million or 16%, compared with $197.5 million for the same period in 2004. The growth in 2005 has resulted principally from acquisitions.

For the nine months ended September 30, 2005 operating income was $15.3 million, or 6.7% of revenue, compared with $11.9 million, or 6.0% of revenue for the first nine months of 2004.

Net income was $3.1 million, or $0.34 per diluted share, for the quarter ended September 30, 2005, compared with $2.3 million, or $0.25 per diluted share, for the third quarter of 2004. For the nine months ended September 30, 2005 net income was $8.5 million, or $0.92 per diluted share, compared with $6.5 million, or $0.72 per diluted share, for the same period in 2004.

Business Highlights

Regarding performance for the quarter, James P. Regan, President, Chairman and CEO, said, “Our profit margin and earnings exceeded expectations for the quarter. In fact, earnings per share for the third quarter grew by 36% and profit margin grew by 25% on year-over-year comparisons. Seeing the results of our profit margin improvement initiatives, we’re delighted with our third quarter earnings performance.

“From a revenue standpoint, our growth in the third quarter of 12% reflects a continuing trend in contract award delays. While we see this situation as temporary, we will remain cautious with our short-term outlook until we see evidence of improvement.

“Several contract wins in the quarter, bids awaiting award backlog of $488 million, a new business opportunity pipeline which stands at an all-time high, and terrific progress in launching the DESP II program underlie our strong optimism looking forward into 2006,” Regan added.

Company Guidance

The company currently estimates revenues in the range of $303 to $306 million and earnings per diluted share in the range of $1.24 to $1.27 including the $0.13 per share impact of the sale of stock during the second quarter. For the fourth quarter of the year the company expects to book revenues in the range of $74 to $77 million and report earnings per diluted share of $0.31 to $0.34.
