KELLY SERVICES REPORTS 1st QUARTER 2011 RESULTS

TROY, MI (May 11, 2011) — Kelly Services, Inc. (NASDAQ: KELYA) (NASDAQ: KELYB), a leader in providing workforce solutions, today announced results for the first quarter.

Carl T. Camden, President and Chief Executive Officer, announced revenue for the first quarter of 2011 totaled $1.3 billion, a 19% increase compared to the corresponding quarter in 2010.

Earnings from operations for the first quarter of 2011 totaled $1.6 million, compared to losses from operations of $1.6 million reported for the first quarter of 2010. Included in the results from operations are restructuring charges of $4.0 million in the first quarter of 2011 and $4.4 million in the first quarter of 2010. Excluding restructuring charges, earnings from operations were $5.6 million in the first quarter of 2011 and $2.8 million in the first quarter of 2010.

Diluted earnings per share in the first quarter of 2011 were $0.03 compared to first quarter 2010 losses of $0.06 per share. Excluding restructuring charges, diluted earnings per share were $0.14 in the first quarter of 2011 and $0.05 in the first quarter of 2010.

Commenting on the first quarter results, Camden stated, “We continue to see evidence of a solid, sustainable economic recovery. Kelly’s revenue growth for the period certainly confirms that we are on track for a profitable year.”

Camden added, “Until full confidence is restored, and employers remain cautious about ramping up too aggressively, this environment seems to favor the staffing industry — and we intend to capitalize on the opportunities presented.

“Going forward, Kelly is committed to improving our competitive position and enhancing shareholder value by delivering customer-focused workforce solutions — spanning traditional staffing, professional and technical offerings, and outsourcing and consulting services, and maintaining talent excellence throughout our company.”

RECONCILIATION OF NON-GAAP MEASURES
(UNAUDITED)

Management believes that the non-GAAP (Generally Accepted Accounting Principles) information excluding the restructuring charges is useful to understand the Company’s fiscal 2011 financial performance and increases comparability. Specifically, Management believes that excluding this item allows for a more meaningful comparison of current period operating performance with the operating results of prior periods. These non-GAAP measures may have limitations as analytical tools because they exclude items which can have a material impact on cash flow and earnings per share. As a result, Management considers these measures, along with reported results, when it reviews and evaluates the Company’s financial performance. Management believes that these measures provide greater transparency to investors and provide insight into how Management is evaluating the Company’s financial performance. Non-GAAP measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
