COMSYS IT PARTNERS, INC. FINALIZES ACCOUNTING TREATMENT FOR CONSIDERATION TO
BE PAID ON 2007 ACQUISITION

HOUSTON, TX (May 12, 2008) — COMSYS IT Partners, Inc. (NASDAQ:CITP), a leading provider of information technology staffing and consulting services, today announced that the Company has finalized its accounting treatment for the previously disclosed $3.4 million payment to be made at the end of 2008 related to its acquisition of Praeos Technologies, Inc. (“Praeos”) that was consummated in December 2007, and in conjunction with the finalization of the accounting treatment, the Company will file its first quarter financial statements on Form 10-Q today. The Form 10-Q filing was due May 9, 2008.

The $3.4 million payment is one part of the overall consideration paid in the acquisition of Praeos. Pursuant to the terms of an agreement between the shareholders of Praeos and certain employees of Praeos (“Participants”), $3.4 million of the purchase consideration was placed into a cash escrow on the closing date and is payable to the Participants if they continue to be employed by Praeos for one year after the acquisition date. If there are no Participants remaining in employment on the one-year anniversary date, the funds will be paid to the former shareholders of Praeos.

After final review of the terms and conditions of the payment and the appropriate accounting literature, the Company has concluded that the $3.4 million of consideration should be treated as a compensatory arrangement and expensed ratably during 2008. If, on the one-year anniversary of the closing date, the employees are no longer with the Company and the $3.4 million is paid to the former shareholders, the Company will reverse the recognized compensation expense and record additional purchase price (goodwill). Accordingly, the Company has recorded a pre-tax compensation expense charge (reflected as selling, general and administrative expense) of approximately $0.8 million in the first quarter 2008 financial statements included in the Company’s Form 10-Q to be filed today. Previously the Company had disclosed the nature of the anticipated payment and that the Company was in the process of finalizing the accounting treatment for the Praeos acquisition.

With the additional compensation expense in the first quarter of 2008, the Company’s net income for the quarter was $5.1 million, or $0.25 per diluted share, as compared to net income of $5.6 million, or $0.27 per diluted share, as announced in the Company’s earnings release on May 1, 2008 (“May 1 Release”). The difference between the amounts reported in the May 1 Release and today’s release represents the impact of the aforementioned compensation expense and the related income tax effect. No changes were made to any other components of operating results. The finalization of this accounting treatment does not change the total consideration paid by the Company in the Praeos acquisition or COMSYS’ operating cash flows. The remaining fiscal quarters of 2008 will have a similar compensation charge that will be nonrecurring after 2008. In addition, the Company anticipates that it will receive the benefit of the tax deduction for the compensation payment. This deduction resulted in a reduction in the Company’s 2008 effective tax rate from 24% to 21%.

Larry Enterline, Chief Executive Officer, commented “even though the final accounting for the compensation charge will reduce our net income results for 2008, it is not indicative of the positive cash

flow and the strength of our business or the current and future value to the Company’s shareholders that we expect from our ongoing operations.”

Second Quarter 2008 Financial Guidance

The Company is revising its guidance for the second quarter of 2008 to include the impact of the additional compensation charge of $0.8 million expected to be incurred as described above. No other changes to our previously announced guidance have been made. For the second quarter of 2008, the Company expects to report revenue in a range of $177 million to $183 million and net income in the range of $5.0 million to $6.0 million, or approximately $0.24 to $0.29 per diluted share, on the same number of billing days as the first quarter of 2008. These estimated net income amounts are based on an effective tax rate of 21%. Management does not expect to pay any substantial amount of cash taxes in 2008. Assuming the Company continues to be profitable, management expects to release the valuation allowance during 2008 and begin to provide for taxes at the full statutory rate.

These estimates and assumptions reflect the Company’s best judgment based on currently known market conditions and other factors relating to its operations and business environment, all of which are difficult to predict and many of which are beyond its control, including:

• the Company’s success in attracting, training, retaining and motivating billable consultants and key officers and employees;

• the Company’s ability to shift a larger percentage of its business mix into IT solutions, project management and business process outsourcing and, if successful, the Company’s ability to manage those types of business profitably;

• changes in levels of unemployment and other economic conditions in the United States, or in particular regions or industries;

• weakness or reductions in corporate information technology spending levels;

• the Company’s ability to maintain existing client relationships and attract new clients in the context of changing economic or competitive conditions;

• whether governments will amend existing regulations or impose additional regulations or licensing requirements in such a manner as to increase the Company’s costs of doing business.

Although the Company believes its estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond its control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this report are not guarantees of future performance, and the Company cannot assure any reader that those statements will be realized or that the forward-looking events and circumstances will occur.
