•Q4 revenue was flat; down 1.3% in constant currency

•Q4 adjusted EBITDA margin increased 60 basis points to 2.6% driven by meaningful reduction in operating expenses resulting from business transformation initiatives

TROY, Mich. (February 15, 2024) – Kelly (Nasdaq: KELYA, KELYB), a leading specialty talent solutions provider, today announced results for the fourth quarter of 2023.

Peter Quigley, president and chief executive officer, announced revenue for the fourth quarter of 2023 totaled $1.2 billion, a 0.1% decrease, or a 1.3% decrease in constant currency, compared to the corresponding quarter of 2022. Year-over-year revenue trends were impacted by customers’ more guarded approach to hiring and initiating new projects or capital spending partially offset by favorable foreign currency impacts.

Kelly reported operating earnings in the fourth quarter of 2023 of $7.3 million, compared to earnings of $4.6 million reported in the fourth quarter of 2022. Earnings in the fourth quarter of 2023 include $14.8 million of charges related to transformation actions and the first-quarter 2024 sale of our European staffing operations. Excluding those charges, adjusted earnings were $22.1 million in the fourth quarter of 2023. Earnings in the fourth quarter of 2022 included a $10.3 million goodwill impairment charge related to RocketPower. Excluding the impairment charge and a $0.9 million gain related to the sale of real property, adjusted earnings from operations were $14.0 million. Adjusted earnings improved primarily as a result of lower selling, general and administrative expenses, partially offset by unfavorable business mix and lower permanent placement fees which resulted in lower gross profit.

Earnings per share in the fourth quarter of 2023 were $0.31 compared to a loss per share of $0.02 in the fourth quarter of 2022. Included in earnings per share in the fourth quarter of 2023 were restructuring charges, net of tax, of $0.16. In addition, there were $0.46 per share of tax adjustments, transaction costs, and an unrealized loss on a forward contract, all net of tax, related to the first-quarter 2024 sale of our European staffing operations. Included in the loss per share in the fourth quarter of 2022 is a $0.23 per share goodwill impairment charge, net of tax, related to RocketPower, partially offset by a $0.02 per share gain on sale of real property, net of tax. On an adjusted basis, earnings per share were $0.93 in the fourth quarter of 2023, an improvement from $0.18 per share in the corresponding quarter of 2022.

“In the fourth quarter, we captured steady demand in Education and most of our outcome-based specialties in P&I, which continue to demonstrate resilience amid a challenging operating environment. We remained focused on the future as well, driving significant progress on our transformation initiatives while completing the sale of Kelly’s European staffing operations which we closed in early January, unlocking more than $100 million of capital and additional net margin expansion,” said Quigley. “Taken together, these accomplishments have propelled Kelly’s EBITDA margin to 3% entering 2024 – a step change from the company’s historical average of approximately 2%. As we continue to build a more efficient, effective, and focused enterprise, I am confident we are well positioned to capture increased customer demand when the operating environment rebounds and accelerate profitable growth.”

Kelly also reported that on February 13, its board of directors declared a dividend of $0.075 per share. The dividend is payable on March 13, 2024, to stockholders of record as of the close of business on February 27, 2024.
