KELLY® REPORTS

FIRST-QUARTER 2021 EARNINGS

Financial Highlights

•Q1 revenue down 4.4%, down 5.5% in constant currency, as pandemic disruption moderates

•Q1 operating earnings of $10.6 million, compared to a reported loss for the corresponding period last year

•Q1 earnings per share of $0.64, or $0.12 on an adjusted basis, compared to adjusted earnings per share of $0.20 for the corresponding period last year

TROY, Mich. (May 13, 2021) – Kelly (Nasdaq: KELYA) (Nasdaq: KELYB), a leading specialty talent solutions provider, today announced results for the first quarter of 2021.

Peter Quigley, president and chief executive officer, announced revenue for the first quarter of 2021 totaled $1.2 billion, a 4.4% decrease, or down 5.5% in constant currency, compared to the corresponding quarter of 2020. Revenue declined year-over-year in the quarter as the effects of the COVID-19 crisis moderated but continued to have an impact on customer demand and the supply of available talent.

Earnings from operations in the first quarter of 2021 totaled $10.6 million, compared to a loss of $111.8 million reported in the first quarter of 2020. The 2020 first-quarter results include a $147.7 million goodwill impairment charge and an $8.7 million restructuring charge, partially offset by a $32.1 million gain on sale of assets. On an adjusted basis, 2020 earnings from operations were $12.5 million.

Diluted earnings per share in the first quarter of 2021 were $0.64 compared to a loss of $3.91 per share in the first quarter of 2020. Included in the earnings per share in the first quarter of 2021 is a non-cash gain, net of tax, on Kelly’s investment in Persol Holdings common stock of $0.52. Included in the loss per share in the first quarter of 2020 is a $3.18 per share goodwill impairment charge, net of tax, a $1.38 per share loss from a non-cash loss on Kelly’s investment in Persol Holdings common stock, net of tax, and a $0.17 restructuring charge, net of tax, partially offset by a $0.61 gain on sale of assets, net of tax. On an adjusted basis, earnings per share were $0.12 in the first quarter of 2021 compared to $0.20 in the corresponding quarter of 2020.

“We’re seeing strong demand across all of our operating segments. This translated into sustained, sequential revenue improvements in our Education, OCG, International, and Science, Engineering & Technology business segments. We’re also seeing improving revenue growth rates in our Professional & Industrial segment and are taking steps to capture even more of the stronger demand, which now exceeds pre-pandemic levels,” said Quigley. “Every segment added numerous wins to their portfolio in the first quarter, and we're pleased with the overall progress and healthy sales pipelines across our specialties. We're moving forward in this recovery with optimism, well-positioned to capture organic specialty growth and committed to a bold M&A strategy that captures inorganic growth, as evidenced by our recent Softworld acquisition, which is the largest deal in Kelly’s history.”

RECONCILIATION OF NON-GAAP MEASURES

(UNAUDITED)

Management believes that the non-GAAP (Generally Accepted Accounting Principles) information excluding the 2020 goodwill impairment charge, the 2021 and 2020 gains and losses on the investment in Persol Holdings, the 2020 gain on sale of assets and the 2020 restructuring charges, are useful to understand the Company's fiscal 2021 financial performance and increases comparability. Specifically, Management believes that removing the impact of these items allows for a meaningful comparison of current period operating performance with the operating results of prior periods. Management also believes that such measures are used by those analyzing performance of companies in the staffing industry to compare current performance to prior periods and to assess future performance.

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.

(1) The goodwill impairment charge is the result of an interim impairment test the Company performed during the first quarter of 2020, due to a triggering event caused by a decline in the Company's common stock price.

(2) The gains and losses on the investment in Persol Holdings represent the change in fair value of the investment during the period presented and the related tax expense and benefit.
