KFORCE REPORTS SECOND QUARTER

REVENUE OF $274.0 MILLION AND EPS OF $0.17

TECH FLEX UP 7.6% SEQUENTIALLY AND 15.4% YEAR-OVER-YEAR

TAMPA, FL., August 2, 2011 (GLOBE NEWSWIRE) — Kforce Inc. (Nasdaq: KFRC), a provider of professional staffing services and solutions, today announced results for its second quarter of 2011. Revenue for the quarter ended June 30, 2011 was $274.0 million compared to $262.4 million for the quarter ended March 31, 2011, an increase of 4.4% and compared to $246.1 million for the quarter ended June 30, 2010, an increase of 11.3%. For the quarter ended June 30, 2011, Kforce reported net income of $6.8 million, or $0.17 per share, versus $4.8 million, or $0.12 per share, for the quarter ended March 31, 2011, an increase of 40.2% in net income and 41.7% in EPS. Net income and EPS for the second quarter of 2011 increased 31.9% and 30.8%, respectively, versus the second quarter of 2010, which had net income of $5.1 million, or $0.13 per share.

“We are pleased with the performance of our Technology (Tech) and Health Information Management (HIM) businesses and the continued strength in Search, which are up 15.2%, 21.2% and 23.5%, respectively, on a year-over-year basis. However, we are not satisfied with the performance of our government and Kforce Clinical Research businesses or the mortgage related component of Finance & Accounting (FA), which continue to be impacted by their particular operating environment challenges. We believe we have made significant progress adjusting our operating models in these businesses and have confidence in our great teams. Overall, we are pleased with our quarterly revenues of $274.0 million, which represents a Firm record, and earnings of $0.17 per share. This represents year-over-year growth of 11.3% and 30.8%, respectively. We continue to leverage our National Recruiting Center (NRC) and Strategic Accounts teams to capture revenue opportunities and provide operating expense leverage. We plan to continue optimizing the investments we have made and to be selective regarding additional investments during this uncertain economic environment.

We believe Kforce is well positioned to service our clients’ increasing desire for a more flexible workforce during this unique temporary employment-led recovery. We remain committed to our goal to surpass prior peak earnings in the cycle with a higher quality revenue stream that is less dependent upon permanent placement revenue,” said David L. Dunkel, Chairman and CEO.

William L. Sanders, President said, “Our key performance indicators and discussions with clients indicate that demand continues to be solid, particularly in Tech, HIM and FA. Against this backdrop, Kforce is committed to our operational objectives for 2011 and beyond to further penetrate and accelerate growth at existing strategic accounts, compete for additional customer share and selectively target new accounts where our service offerings and business model add value to our clients. We also expect to continue to improve profitability through the leverage that exists in our highly advanced operating platform and by further evolving the NRC, which allows us to profitably serve certain clients and niches that would not be possible under a traditional staffing model. We remain focused on adapting to the changing needs of all of our businesses to optimize performance and position the Firm for long-term success.”

Mr. Sanders noted additional operational results for the second quarter include:

Joseph J. Liberatore, Chief Financial Officer, said, “We are pleased with second quarter results, particularly in our continued ability to demonstrate strong discipline in controllable areas of the Firm, such as expense management and collection of accounts receivable. We continue to be confident in the long-term outlook of our business. The second quarter of 2011 contained 64 billing days compared to 63 billing days in Q1 ‘11, and 64 billing days in Q2 ‘10. We believe our second quarter results reflect our strong culture, tenured sales associate population and a continued focus on execution in all aspects of the business, including improving client relationships, solid expense management and continued efficiencies and operating leverage provided by the NRC.”

Financial highlights for the second quarter include:

Mr. Liberatore stated, “In addition, looking forward to the third quarter of 2011, we expect revenue may be in the $276 million to $283 million range and earnings per share in the range of $0.17 to $0.19. Both the second and third quarters of 2011 have 64 billing days.”

Quarterly Adjusted EBITDA

Adjusted EBITDA, a non-GAAP financial measure, is defined as net income before non-cash impairment charges, interest, income taxes, depreciation and amortization and amortization of stock-based compensation expense. Adjusted EBITDA should not be considered a measure of financial performance under generally accepted accounting principles. Items excluded from Adjusted EBITDA are significant components in understanding and assessing financial performance.

Quarterly Net Income before Equity-Based Compensation Expense

“Net Income before Equity-Based Compensation Expense”, a non-GAAP financial measure, is defined as net income before compensation expense incurred in conjunction with share-based payment awards and alternative long-term incentive awards. Kforce measures the cost of employee services received in exchange for an equity based award based on the grant-date fair value of the award (with limited exceptions). That cost is recognized over the period in which the employee is required to provide service in exchange for the award, which is usually the vesting period.

Adjusted EBITDA and Net Income before Equity-Based Compensation Expense are key measures used by management to evaluate its operations and to provide useful information to investors. These measures should not be considered in isolation or as an alternative to net income, cash flows data or other financial statement information presented in the consolidated financial statements as indicators of financial performance or liquidity. These measurements are not determined in accordance with generally accepted accounting principles and are thus susceptible to varying calculations. The measures as presented may not be comparable to similarly titled measures of other companies.
