KFORCE REPORTS REVENUES OF $270.2 MILLION AND EPS OF $0.26 FOR THE THIRD QUARTER OF 2012

NET INCOME AND EPS FROM CONTINUING OPERATIONS UP 46.6% AND 52.9%

TAMPA, FL, October 30, 2012 (GLOBE NEWSWIRE) — Kforce Inc. (Nasdaq: KFRC), a provider of professional staffing services and solutions, today announced results for its third quarter of 2012. Revenues from continuing operations for the quarter ended September 30, 2012 were $270.2 million compared to $274.1 million for the quarter ended June 30, 2012, a decrease of 1.4% and compared to $261.0 million for the quarter ended September 30, 2011, an increase of 3.5%. In the quarter ended September 30, 2012, Kforce reported net income of $9.3 million, or $0.26 per share, versus $8.9 million, or $0.24 per share, excluding the goodwill impairment charge, for the quarter ended June 30, 2012. Net income and earnings per share for the third quarter of 2012 increased 9.7% and 18.2%, respectively, versus net income of $8.4 million, or $0.22 per share, for the third quarter of 2011. Net income and earnings per share from continuing operations for the quarter ended September 30, 2012 of $9.3 million and $0.26 per share, respectively, increased 46.6% and 52.9%, respectively, from $6.3 million, or $0.17 per share, for the quarter ended September 30, 2011.

David L. Dunkel, Chairman and CEO, said, “We are pleased with our Q3 ‘12 results as Kforce reported revenues for the quarter of $270.2 million and earnings per share of $0.26. The environment for professional staffing and the demand for our services, particularly in technology staffing, continues to be positive. Over the past few quarters, however, revenue growth has slowed as the uncertain economic outlook is dampening demand. The unemployment rate among college-degreed workers is roughly half that of the overall U.S. rate of unemployment, and is substantially lower in several of the skill sets in which Kforce specializes. We continue to see bill rates increase as supply for highly skilled candidates remains tight. We believe our diverse service offerings and highly elastic front and back office platforms position Kforce well to navigate through the significant uncertainties that exist in the macroeconomic environment. I want to thank all of our employees, consultants and clients for making Q3 ‘12 another successful quarter for Kforce.”

William L. Sanders, President, said, “The Firm continued its solid performance in the third quarter of 2012, where we experienced a flex margin increase of 30 basis points sequentially and 40 basis points year-over-year, which was primarily driven by the increase in the spread between bill and pay rates for our Tech segment, which is our largest segment. We intend to continue to aggressively manage our client portfolio to optimize both volume and rate. During the third quarter, we were able to continue to take advantage of our highly advanced sales and delivery platform that leverages our field associates, Strategic Accounts strategy and the National Recruiting Center to profitably grow revenues with both large and small clients. Discussions with our clients and certain key performance indicators indicate demand for temporary staffing to be stable, though growth is being impacted by prolonged decision making from our clients as well as an increase in conversions. Kforce continues to aggressively pursue business opportunities with the goal of continuing to gain client and market share.”

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

Joseph J. Liberatore, Chief Financial Officer, said, “The Firm continued to perform well in Q3 ‘12. Q3 ‘12 contained 63 billing days while Q2 ‘12 and Q3 ‘11 each contained 64 billing days. The Firm has continued to improve earnings in this environment by improving bill/pay spreads through continued selective investments in its stronger products and markets and by generating operating leverage through efficiencies and scale. We expect modest revenue growth and Flex gross margin expansion in the near term and believe operating efficiencies will result in continued improvements in operating margins. We will continue to focus on execution in all aspects of our business including improving client relationships, solid expense management and continued efficiencies.”

Financial highlights for the third quarter include:

Mr. Liberatore stated, “In addition, looking forward to the fourth quarter of 2012, we expect revenues may be in the $267 million to $273 million range and earnings per share in the range of $0.22 to $0.24. The fourth quarter of 2012 has 62 billing days, one less than the third quarter of 2012. This guidance does not factor the potentially significant impact from the still unfolding dynamics as a result of Hurricane Sandy. Approximately 30% of Kforce revenue is derived from the Mid Atlantic - Northeast corridor.”

On Tuesday, October 30, 2012, Kforce will host a conference call to discuss these results. The call will begin at 5:00 p.m. Eastern Time.

Quarterly Adjusted EBITDA

Adjusted EBITDA, a non-GAAP financial measure, is defined as earnings before discontinued operations, non-cash impairment charges, interest, income taxes, depreciation and amortization and 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 and Impairment Charge

“Net Income before Equity-Based Compensation Expense and Impairment Charge”, a non-GAAP financial measure, is defined as income (loss) from continuing operations before compensation expense incurred in conjunction with share-based payment awards, alternative long-term incentive awards and non-cash impairment charges. 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 Net Income and Earnings Per Share Before Impairment Charge, Adjusted EBITDA and Net Income before Equity-Based Compensation Expense and Impairment Charge 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.
