FOR IMMEDIATE RELEASE

   ManTech Reports Record Third Quarter 2003 Results

FAIRFAX, Virginia, October 29, 2003 – ManTech International Corporation (NASDAQ: MANT), a leading provider of information technology and technical services solutions to the Department of Defense and the intelligence community, today announced record operating results for the third quarter of 2003. ManTech’s revenue for the third quarter 2003 increased year-over-year 39% to $181.6 million, operating income increased 48% to $16.2 million and fully diluted Earnings Per Share (EPS) rose 21% to $0.29.

“ManTech’s third quarter results reflect our success at positioning the company to play a meaningful role in the market for national security. We have gained traction across the entire spectrum of our defense, intelligence and homeland security markets as evidenced by the fact that now approximately 93% of our revenue for the quarter was derived from our contracts with the Department of Defense and intelligence community,” stated George J. Pedersen, Chairman of the Board, CEO and President of ManTech International Corporation. “Strong budget trends for our markets, our solid balance sheet, and improving operating results will allow us to capitalize on the momentum created from our fully integrated, uniform business platform.”

ManTech International Corporation reported revenue for the quarter ending September 30, 2003 of $181.6 million, up from $130.4 million for the same period in 2002, an increase of 39%. The results reflect an organic growth rate of over 12% from the $161.5 million in pro forma revenue for the comparable period in 2002, which includes the revenue for each period of the companies acquired by ManTech since that time. This revenue growth was primarily attributable to new business supporting national security programs for the Department of Defense and intelligence community.

Operating income for the quarter was $16.2 million, an increase of 48% over 2002. Operating margin for the quarter expanded to 8.9% compared with 8.4% for the same period in 2002. The margin expansion in the quarter is attributable both to higher margin contributions from acquired companies and to operating efficiencies. Net income for the quarter rose 47% to $9.2 million from $6.3 million in 2002, while fully diluted EPS were $0.29, up from $0.24 in 2002.

ManTech recently received contract awards and contract expansions with an estimated value in excess of $260 million, including previously unannounced contract awards and existing contract expansions totaling approximately $160 million. Of particular note, ManTech won several significant blanket purchase agreements (BPAs) during the quarter. ManTech was selected as one of three prime contractors by the Department of Justice, under a BPA that is estimated to be approximately $100 million per fiscal year, according to the solicitation, to support the Justice Consolidated Office Network (JCON) Program. ManTech also won a GSA-based BPA contract with the Marine Corps Systems Command to provide a wide variety of technical support services, including specialized IT services and engineering support, software development, test and evaluation support and C4I systems integration. Further, the company won a multi-year contract with the National Security Agency to provide full life cycle engineering, operations, and maintenance support for several NSA mission-related systems.

ManTech reported backlog of $1.5 billion as of September 30, 2003, compared with $1.2 billion on the same date in 2002. Funded backlog as of September 30, 2003 was $410.8 million, an increase of 81% over the same date in 2002. At the end of the third quarter, ManTech had approximately $1.3 billion in proposals under evaluation and a pipeline of qualified opportunities over $4.5 billion.

ManTech derived about 90% of its revenue during the quarter ended September 30, 2003 from prime contracts, and approximately 44% of its revenue for the period came from work under GSA schedule contracts. Revenue from the Department of Defense and the intelligence community accounted for approximately 93% of revenue for the third quarter ending September 30, 2003. Revenue from work in secure systems and information technology solutions increased to 85% of revenue in the third quarter 2003 from 78% in 2002.

NOTE: EBITDA is defined as net income plus the loss from discontinued operations, interest expense, income taxes, depreciation and amortization, other expense, minority interest, and minus other income.

EBITDA as calculated by us may be calculated differently than EBITDA for other companies. We have provided EBITDA because we believe it is a commonly used measure of financial performance in comparable companies and is provided to help investors evaluate companies on a consistent basis, as well as to enhance an understanding of our operating results. EBITDA should not be construed as either an alternative to net income as an indicator of our operating performance or as an alternative to cash flows as a measure of liquidity.
