Management Commentary

David L. Dunkel, Chairman and Chief Executive Officer commented, “We are very pleased with our fourth quarter performance as our largest business, Tech Flex, grew 9.0% year-over-year on a billing day basis. Tech Flex revenue accelerated meaningfully towards the end of the quarter due to fewer assignment ends and stronger new assignment starts than anticipated. We believe this is related to the acute labor shortage, especially with highly-skilled resources. The pace of digital transformation continues at a rapid pace, forcing organizations across all industries to increase their technology investments. We believe the secular drivers of technology will transcend traditional cyclical patterns as business models are transformed."

Joseph J. Liberatore, President, said, “We believe that the broad-based growth we are experiencing in Tech Flex is a result of the actions taken and investments made over the last several years to better segment our client portfolio and optimize the alignment of our associates within the portfolio. We are encouraged with the strong finish to 2018 within our Tech Flex business and are pleased with the progress in improving associate productivity.”

End Note:

¹ A non-GAAP financial measure, refer to reconciliation in the Adjusted Financial Performance Measures section.

David M. Kelly, Chief Financial Officer, said, “We continue to make solid progress improving our profitability as operating margin in the fourth quarter of 6.2% increased 80 basis points year-over-year. In addition, we are converting our revenue growth and improved profitability into higher levels of operating cash flow, which was $23.0 million in the fourth quarter and $87.7 million for the full year. This allowed us to not only decrease outstanding borrowings under our Credit Facility by nearly $45 million, but also return more than $30 million of our free cash flow to our shareholders. We are also pleased to announce that our Board of Directors approved a first quarter cash dividend of $0.18 per share, which will be payable on March 22, 2019 to shareholders of record as of the close of business on March 8, 2019."

Guidance and Outlook

Looking forward to the first quarter of 2019, there will be 63 billing days, as compared to 62 billing days in the fourth quarter of 2018, and 64 billing days in the first quarter of 2018. Current estimates for the first quarter of 2019 are:

• Revenue of $351 million to $356 million

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	$	(267	)	$	(1,103	)

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 an alternative 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. During the three months and year ended December 31, 2018, the Firm did not have any non-GAAP adjustments.
