Kforce Reports Fourth Quarter Revenue of $258.5 Million and EPS of $0.16

TAMPA, Fla., Feb. 8, 2011 (GLOBE NEWSWIRE) — Kforce Inc. (Nasdaq:KFRC), a provider of professional staffing services and solutions, today announced results for its fourth quarter of 2010. Revenue for the quarter ended December 31, 2010 was $258.5 million compared to $259.5 million for the quarter ended September 30, 2010, a decrease of 0.4%, and compared to $224.6 million for the quarter ended December 31, 2009, an increase of 15.1%. For the quarter ended December 31, 2010, Kforce reported net income of $6.3 million, or $0.16 per share, versus $6.4 million, or $0.16 per share, for the quarter ended September 30, 2010, a decrease of 1.6% in net income while EPS was flat. Net income and earnings per share for the fourth quarter of 2010 increased 79.4% and 77.8%, respectively, versus the fourth quarter of 2009, which had net income of $3.5 million and $0.09 per share.

Kforce reported total revenue for the year ended December 31, 2010 of $990.8 million compared to $910.1 million for 2009, an increase of 8.9%. Net income was $20.6 million, or $0.51 per share, for the year ended December 31, 2010, compared to net income of $12.9 million, or $0.33 per share, for 2009, which represents an increase of 60.3% in net income and 54.5% in earnings per share.

“We are pleased with our fourth quarter results, particularly the year-over-year increases in Tech Flex and FA Flex of 18.5% and 34.1%, respectively, as we continue to leverage our National Recruiting Center (NRC) and Strategic Accounts groups to capture revenue opportunities. We also continue to perform well in permanent placement with a year-over-year increase of 49.4%. The U.S. economic environment in 2010 was unique in that we have seen a disproportionate amount of private sector hiring coming through the temporary portion of payroll. We believe Kforce is well positioned to service our clients’ increasing desire for a more flexible workforce during this unique temporary employment led recovery, which we believe may continue to contribute to a sustained secular shift toward a flexible staffing model. We believe that we will surpass prior peak earnings earlier in the cycle with a higher quality revenue stream that is less dependent upon permanent placement revenue. We are proud of our 2010 results and we remain optimistic about the Firm’s prospects. I want to thank all of our employees, consultants and clients for making 2010 a successful year for Kforce,” said David L. Dunkel, Chairman and CEO.

William L. Sanders, President, said, “Discussions with clients, as well as our internal key performance indicators (KPI’s), indicate that demand continues to accelerate, particularly in Tech and FA. Accordingly, the Firm continues to focus its efforts on the optimization of the NRC, Strategic Accounts and field sales teams to take advantage of this strengthening demand. We believe that our strong sales and delivery operating platform and highly tenured sales population provides exceptional service to our clients. 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 fourth quarter include:

Joe Liberatore, Chief Financial Officer, said, “The Firm continued to perform well in Q4 ‘10, both in terms of revenue and earnings per share. Q4 ‘10 and Q4 ‘09 each contained 61 billings days while Q3 ‘10 contained 64 billing days. We believe our fourth 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, expanding bill/pay rate spreads, solid expense management and optimizing cash flow.”

Mr. Liberatore indicated financial highlights for the fourth quarter to include:

Mr. Liberatore stated, “Looking forward to the first quarter of 2011, we expect revenue may be in the $259 million to $265 million range and earnings per share in the range of $0.12 to $0.14 per share, which reflects an impact of approximately $0.05 per share of payroll taxes. The first quarter of 2011 has 63 versus 61 billing days in the fourth quarter of 2010.”

On Tuesday, February 8, 2011, Kforce will host a conference call to discuss these results. The call will begin at 5:00 p.m. Eastern Time. The dial-in number is 877-344-3890.

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.
