Kelly Reports Second-Quarter 2023 Earnings,

Substantial Progress on Business Transformation

•Q2 revenue down 3.9%; down 4.5% in constant currency; organic revenue down 2.2% in constant currency

•Q2 gross profit down 8.3%; GP rate, 19.8%, down 90 bps year-over-year due primarily to lower permanent placement fees as customer full-time hiring decelerates

•Q2 operating earnings of $6.2 million, including $8.0 million of transformation-related restructuring and impairment charges, or $14.2 million on an adjusted basis

•Comprehensive business transformation program expected to drive meaningful improvement in EBITDA margin beginning in the second half of 2023

TROY, Mich., (August 10, 2023) – Kelly (Nasdaq: KELYA, KELYB), a leading global specialty talent solutions provider, today announced results for the second quarter of 2023.

Peter Quigley, president and chief executive officer, announced revenue for the second quarter of 2023 totaled $1.2 billion, a 3.9% decrease, or 4.5% decrease in constant currency, compared to the corresponding quarter of 2022, with organic, constant currency revenue down 2.2%. Year-over-year revenue trends were impacted by the sale of Russian operations in July 2022 and customers’ more guarded approach to hiring, partially offset by favorable currency impacts.

“In the second quarter, we remained focused on seeking out pockets of demand in more resilient markets, while the effects of ongoing macroeconomic uncertainty became more noticeable in certain parts of our portfolio,” said Quigley. “Our Education segment and higher-margin outcome-based solutions in P&I continued to deliver year-over-year growth, while lower demand for temporary and permanent placement services impacted results in our P&I and SET segments.”

Kelly reported operating earnings in the second quarter of 2023 of $6.2 million, compared to earnings of $8.2 million reported in the second quarter of 2022. Earnings in the second quarter of 2023 include $8.0 million of transformation-related restructuring and impairment charges. Excluding the transformation-related charges, adjusted earnings from operations were $14.2 million. Earnings in the second quarter of 2022 included an $18.5 million asset impairment charge related to our Russian operations and a $4.4 million gain on sale of assets related to underutilized real property and adjusted earnings were $22.3 million. Adjusted earnings declined year-over-year primarily as a result of lower revenues.

Earnings per share in the second quarter of 2023 were $0.20 compared to earnings per share of $0.06 in the second quarter of 2022. Included in the earnings per share in the second quarter of 2023 is an $0.11 loss per share related to transformation-related restructuring charges, net of tax, and a $0.05 loss per share, net of tax, related to an asset impairment charge. Included in the second quarter of 2022 is a $0.48 loss per share, net of tax, asset impairment charge, partially offset by a $0.08 per share gain on sale of real property, net of tax. On an adjusted basis, earnings per share were $0.36 in the second quarter of 2023, a decline of 20% from $0.45 per share in the corresponding quarter of 2022.

Quigley went on to provide an update on the company's business transformation following the strategic restructuring actions it announced in July. “The change we set out to create through this transformation is no longer hypothetical. The efficiency actions we have implemented to date will deliver an immediate, meaningful improvement to the company's EBITDA margin, creating a strong foundation for further EBITDA margin expansion going forward. With these actions unlocking additional resources to invest in our future, we are quickly shifting our focus to the growth phase of our transformation to realize the full potential of our specialty strategy.”

As a result of the strategic restructuring and additional cost optimization actions that Kelly will complete in 2023, the Company expects an adjusted EBITDA margin of approximately 3% exiting 2023. Assuming the benefit of a full year of its transformation-related savings and no change in current top-line expectations, the Company would expect to achieve a normalized, adjusted EBITDA margin in the range of 3.3% to 3.5%.

RECONCILIATION OF NON-GAAP MEASURES

(UNAUDITED)

Management believes that the non-GAAP (Generally Accepted Accounting Principles) information excluding the 2023 restructuring charges, the 2023 impairment charge, the 2022 sale of the Persol Holdings investment, the 2022 losses on the fair value changes of the investment in Persol Holdings, the 2022 losses on foreign currency matters, the 2022 impairment on assets held for sale, and the 2022 gain on sale of assets are useful to understand the Company's fiscal 2023 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.

Management uses Adjusted EBITDA (adjusted earnings before interest, taxes, depreciation and amortization) and Adjusted EBITDA Margin (percent of total GAAP revenue) which Management believes is useful to compare operating performance compared to prior periods and uses it in conjunction with GAAP measures to assess performance. Our calculation of Adjusted EBITDA may not be consistent with similarly titled measures of other companies and should be used in conjunction with GAAP measurements. Management also uses year-to-date free cash flow (operating cash flows less capital expenditures) to indicate the change in cash balances arising from operating activities, net of working capital needs and expenditures on fixed assets.

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) In 2022, the loss on the investment in Persol Holdings represents the change in fair value up until the date of the sale of the investment on February 15, 2022 as well as the loss on the sale of the investment during the period presented and the related tax benefit.

(2) In 2022, the loss on foreign currency matters includes a $20.4 million loss on currency translation resulting from the substantially complete liquidation of the Company's Japan entity, partially offset by a $5.5 million foreign exchange gain on the Japan entity's USD-denominated cash balance. The foreign exchange gain is included in other (income) expense, net in the EBITDA calculation.

(3) Gain on sale of assets in 2022 is related to the sale of under-utilized real property in the second quarter of 2022 and other real property sold in the first quarter of 2022.

(4) Asset impairment charge in the second quarter of 2023 represents the impairment of right-of-use assets related to an unoccupied existing office space lease. In 2022, the asset impairment charge is the impairment of assets held for sale representing the write-down of the net assets of the Russian operations that were classified as held for sale as of the second quarter of 2022.

(5) Restructuring charges in the second quarter of 2023 relate to a comprehensive transformation initiative that includes actions that will further streamline the Company's operating model to enhance organizational efficiency and effectiveness. These restructuring charges include $4.5 million of costs to execute the transformation through the use of an external consultant and $1.1 million of severance. Restructuring charges in the first quarter of 2023 represent severance costs and lease and other terminations as a result of management undertaking actions to further our cost management efforts in response to the current demand levels and reflects a repositioning of our P&I staffing business to better capitalize on opportunities in local markets.

(6) Other, net primarily represents amortization of capitalized hosted software implementation costs.
