KFORCE FOURTH QUARTER REVENUES OF $342.6 MILLION EXCEEDS GUIDANCE

FOURTH QUARTER EPS OF $0.24; ADJUSTED EPS OF $0.45

TAMPA, FL, February 6, 2018 (GLOBE NEWSWIRE) — Kforce Inc. (Nasdaq: KFRC), a provider of professional staffing services and solutions, today announced results for its fourth quarter and full year 2017. Revenues for the quarter ended December 31, 2017 were $342.6 million compared to $341.1 million for the quarter ended September 30, 2017, an increase of 3.7% on a billing day basis, and compared to $326.0 million for the quarter ended December 31, 2016, an increase of 5.1%. Net income for the quarter ended December 31, 2017 was $6.1 million, or $0.24 per share, as compared to $10.1 million, or $0.40 per share, for the quarter ended September 30, 2017, and $9.2 million, or $0.36 per share, for the quarter ended December 31, 2016. The Tax Cuts and Jobs Act (“TCJA”) resulted in a remeasurement of our net deferred tax assets, which negatively impacted fourth quarter net income by $5.4 million, or $0.21 per share. Adjusted earnings per share for the three months ended December 31, 2017 was $0.45 per share.

Kforce reported total revenues for the year ended December 31, 2017 of $1.36 billion, an increase of 2.9%, as compared to $1.32 billion for the year ended December 31, 2016. Net income for the year ended December 31, 2017 was $33.3 million, or $1.30 per share, which represent increases of 1.6% and 4.0%, respectively, compared to 2016.

David L. Dunkel, Chairman and Chief Executive Officer commented, “We are pleased with our fourth quarter results as we exceeded the top end of guidance for revenues and earnings per share, as adjusted for the impact of TCJA. Also, our year-over-year growth rates in our largest business, Tech Flex, continued to accelerate to 5.4% in the fourth quarter, despite the 130 basis point negative impact that the sale of our Global business had on our year-over-year growth rates. Thus, our core Tech Flex business is growing at 6.7% on a year-over-year basis. As we head into Q1 2018, we expect continued strength in our Tech Flex business. We are confident in the structure and strength of our organization and believe that we are well positioned in 2018 to capitalize on significant market opportunities that exist. The demand environment for our services, particularly in Tech Flex, appears very strong as companies continue to invest in technology to more effectively and efficiently meet the needs of their customers and are seeking flexible resources for a portion of their human capital needs. I want to thank all of our clients, consultants and core employees for making our mutual success possible.

Joseph J. Liberatore, President said, “We believe we are pursuing the mix of business that will lead to the greatest long-term success and remain highly focused on the actions necessary to further accelerate revenue growth and associate productivity.”

Mr. Liberatore noted additional operational results for the fourth quarter include:

• Flex revenues of $332.4 million in Q4 2017 increased 4.4%, on a billing day basis, from $328.9 million in Q3 2017 and increased 5.6%, from $314.7 million in Q4 2016.

• Quarterly year-over-year growth in Flex revenues for Tech, FA and GS was 5.4%, 0.3% and 25.7%, respectively.

David M. Kelly, Chief Financial Officer, said, “We remain confident in our belief that we will meet or exceed our 7.5% operating margin target when $1.6 billion in annualized revenue is reached and still expect to achieve an operating margin of at least 6.3% at $1.4 billion in annualized revenue, which we expect to occur in the second quarter of 2018. Over the last three years, we have returned $130.6 million to our shareholders, which is substantially all of our operating cash flows generated over that period. We expect to continue to invest in our business to take advantage of the positive demand environment. We are also pleased to announce that our Board of Directors declared a first quarter cash dividend on Kforce common stock of $0.12 per share. The cash dividend will be payable on March 23, 2018 to shareholders of record as of the close of business on March 9, 2018.”

Highlights for the fourth quarter include:

• Tech Flex gross profit margin of 27.2% in Q4 2017 increased 20 basis points from 27.0% in Q3 2017 and decreased 30 basis points from 27.5% in Q4 2016.

• Selling, general and administrative expense as a percentage of revenues in Q4 2017 was 24.0% which remained flat as compared to Q3 2017 and is down 120 basis points from 25.2% in Q4 2016.

• Operating cash flows in Q4 2017 were $23.7 million compared to $10.1 million in Q4 2016.

• We repurchased approximately 451 thousand shares of common stock on the open market at a total cost of approximately $10.8 million during Q4 2017.

Looking forward to the first quarter of 2018, there will be 64 billing days, as compared to 61 billing days in the fourth quarter of 2017, and 64 billing days in the first quarter of 2017. Current estimates for the first quarter of 2018 are:

• Revenues of $343 million to $347 million

• Earnings per share of $0.35 to $0.38

• Gross profit margin of 29.0% to 29.2%

• Flex gross profit margin of 26.5% to 26.7%

• SG&A expense as a percent of revenue of 24.4% to 24.6%

• Operating margin of 3.8% to 4.2%

• Effective tax rate of 26.0%

Non-GAAP Financial Measures

(In Thousands, Except Per Share Amounts)

(Unaudited)

The following non-GAAP financial measures presented may not provide information that is directly comparable to that provided by other companies, as other companies may calculate such financial results differently. The Company’s non-GAAP financial measures are not measurements of financial performance under GAAP and should not be considered as alternatives to amounts presented in accordance with GAAP. The Company views these non-GAAP financial measures as supplemental and they are not intended to be a substitute for, or superior to, the information provided by GAAP financial results. A reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures is provided below.

Free Cash Flow

“Free Cash Flow”, a non-GAAP financial measure, is defined by Kforce as net cash provided by operating activities determined in accordance with GAAP, less capital expenditures. Management believes this provides an additional way of viewing our liquidity that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our cash flows and is useful information to investors as it provides a measure of the amount of cash generated from the business that can be used for strategic opportunities including investing in our business, making acquisitions, repurchasing common stock or paying dividends. Free Cash Flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. Therefore, we believe it is important to view Free Cash Flow as a complement to our financial statements.

Change in cash and cash equivalents	$	(1,103	)	$	(15	)

Adjusted EBITDA

“Adjusted EBITDA”, a non-GAAP financial measure, is defined by Kforce as net income before depreciation and amortization, stock-based compensation expense, interest expense, net and income tax expense. Adjusted EBITDA should not be considered a measure of financial performance under GAAP. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our past and future financial performance, and this presentation should not be construed as an inference by us that our future results will be unaffected by those items excluded from Adjusted EBITDA. Adjusted EBITDA is a key measure used by management to assess our operations including our ability to generate cash flows and our ability to repay our debt obligations. Management believes it is useful information to investors as it provides a good metric of our core profitability in comparing our performance to our competitors, as well as our performance over different time periods. The measure should not be considered in isolation or as an alternative to net income, cash flows or other financial statement information presented in the consolidated financial statements as indicators of financial performance or liquidity. The measure is not determined in accordance with GAAP and is susceptible to varying calculations, and as presented, may not be comparable to similarly titled measures of other companies.

Adjusted Financial Performance Measures

The "Adjusted Financial Performance Measures" present non-GAAP financial information and should not be considered a measure of financial performance under generally accepted accounting principles. These measures are presented as a supplemental method for assessing the Company’s operating results by adjusting for the impact of certain non-recurring, infrequent or unusual items in a manner that is focused on the performance of our underlying operations. Each of these measures are intended to provide greater consistency, comparability and clarity of our results. Management uses this non-GAAP financial information to assess the Company's core operating results and consequently, management believes it is similarly useful information to investors. These non-GAAP financial measures should not be considered in isolation from, or as a substitute for or superior to, financial measures reported in accordance with GAAP.
