Adecco Group AG agreed to sell its U.S. healthcare staffing business, Soliant Health, Inc., to Olympus Partners for $612 million.

The workforce solutions company said the divestment is part of its wider plan to focus on "globally scalable brands" and digital solutions. Adecco Group CEO Alain Dehaze said Soliant has a "limited scope to expand" outside the U.S. market.

The transaction is expected to be completed by the first quarter of 2020, pending customary closing conditions, and generate a gain for Adecco, the company said.

J.P. Morgan Securities LLC was the exclusive financial adviser to Adecco.

Adecco announced the transaction as it reported a year-over-year drop of 2% in third-quarter revenue, citing "ongoing challenging market conditions" in the U.S. and Europe.
