SRA Announces Financial Results for

First Quarter of Fiscal Year 2011

• Revenue of $424 million, diluted EPS from continuing operations of $0.32

• Record contract awards of $1.1 billion

• Operating cash flow of $35 million

FAIRFAX, Va., November 2, 2010 — SRA International, Inc. (NYSE: SRX), a leading provider of technology and strategic consulting services and solutions to government organizations and commercial clients, today announced operating results for the first quarter of fiscal year (FY) 2011, which ended September 30, 2010.

Revenue for the quarter was $423.9 million, up 1.7% from $416.7 million in the September 2009 quarter, driven by the recent acquisitions of PQA and Sentech. Operating income for the quarter was $30.0 million, for an operating margin of 7.1%. Income from continuing operations was $18.5 million, for a net margin of 4.4%. Diluted earnings per share (DEPS) from continuing operations for the quarter were $0.32. Operating cash flow was $34.8 million and free cash flow was $31.2 million.

During the quarter the company entered into an agreement to sell the Airport Operations Solutions (AOS) business. The transaction is expected to close in the quarter ending December 31, 2010. The results of the AOS business have been included in discontinued operations in our financial statements.

SRA President and CEO Stan Sloane said, “We are pleased to have achieved quarterly contract awards of over $1 billion for the first time in company history. Our book-to-bill ratio over the past twelve months is now 1.5, and our pipeline of opportunities remains strong, with $2.0 billion pending adjudication.”

Executive Vice President and CFO Rick Nadeau added, “We had strong cash flows from operations in the quarter, driven by further improvement in days sales outstanding to 71 days.”

Contract Awards

SRA won new business in the first quarter with potential value of $1.1 billion, if all option years are exercised, for a book-to-bill ratio of 2.6. As of September 30, 2010, the company’s backlog of signed business orders was $5.0 billion, up 10% year-over-year, and the funded portion of backlog was $1.1 billion, up 29% year-over-year.

Major highlights of competitive contract awards in the quarter include:

• Department of Defense. SRA was awarded a re-compete contract to support the receipt and scientific review of research grant applications for DoD’s Congressionally Directed Medical Research Programs. The contract has a potential total value of $100 million over five years, if all options are exercised.

• Classified Contracts. SRA was awarded over $400 million in contract awards in support of classified customers.

SRA was also awarded several multiple-award, IDIQ contracts in the first quarter, which are not included in the company’s quarterly bookings figure, but are expected to drive growth over time. The largest was a prime position on the Management Consulting and Information Management Services domains for the Centers for Disease Control and Prevention’s Information Management Services, or CIMS, contract. This multiple-award IDIQ contract has a total value to all awardees of these two domains of $4 billion over 10 years, if all options are exercised.

Forward Guidance

The company is updating revenue and earnings guidance for Fiscal Year 2011 originally provided on August 11, 2010 to reflect the plan to divest the AOS business. The table below represents management’s current expectations about the company’s future financial performance, based on information available at this time. SRA entered an agreement to acquire Platinum Solutions, Inc. in October. The forward guidance does not include any effect for the Platinum acquisition, or any additional acquisitions or divestitures that SRA might make in the future. The guidance assumes that the FY 2011 diluted weighted-average shares outstanding are 58.0 million, excluding unvested restricted stock awards, and that the allocation of earnings to unvested restricted shares used in the calculation of diluted earnings per share is approximately 1.3% of net income.

Measure	Fiscal Year Ending June 30, 2011
Revenue	$1.77 billion to $1.82 billion
Diluted earnings per share from continuing operations	$1.37 to $1.45

Non-GAAP Financial Measures

The financial measures shown below, organic revenue and free cash flow from continuing operations, are non-GAAP financial measures. These measures are not calculated through the application of GAAP and are not the required form of disclosure by the Securities and Exchange Commission. As such, they should not be considered as substitutes for the most directly comparable GAAP measures and should not be used in isolation, but in conjunction with these GAAP measures. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies. Reconciliations to the most directly comparable GAAP financial measures are included below.

Reconciliation Between Total Revenue and Organic Revenue (Unaudited)

(in thousands)

Organic revenue, as presented, is computed by comparing our actual reported revenue in the current period, including revenue attributable to acquired companies, with adjusted revenue from the prior year period. In arriving at prior year revenue, we include the revenue of acquired companies for the prior year periods comparable to the current-year periods for which the companies are included in our actual reported revenue. Revenue from discontinued operations is not included in reported revenue, and therefore, is not considered in our calculation of organic revenue. The resulting rate is intended to represent our organic, or non-acquisitive, growth or decline year-over-year. We believe that this non-GAAP financial measure provides useful information because it allows investors to better assess the underlying growth rate of our business, including the post-acquisition activity of acquired companies.

	30-Sep-10		30-Sep-09		% Change
Revenue from continuing operations, as reported	$	423,933	$	416,739		1.7	%
Plus: Revenue of acquired companies for the comparable prior year period		—		7,927
Organic revenue	$	423,933	$	424,666		-0.2	%

Reconciliation Between Net Cash Provided by Operating Activities and Free Cash Flow (Unaudited)

(in thousands)

We define free cash flow, as presented, as net cash provided by operating activities less capital expenditures. Cash flows from discontinued operations are excluded from the calculation of free cash flow as these cash flows will not continue in future periods. We believe that this non-GAAP financial measure is useful for investors in analyzing our ability to generate cash flow for purposes such as repaying debt, funding business acquisitions, and repurchasing our common stock.
