BERLIN, March 1 (Reuters) - Daimler Truck reported on Friday a 9.9% adjusted return on sales for its industrial business for 2023, up from 7.7% the prior year, but warned of continued difficult economic conditions and a lack of catch-up effects for the current year.

The truck and bus maker, which said it achieved its full-year targets for 2023, is expecting adjusted return on sales for its key industrial business of between 9.0% and 10.5% in 2024. (Reporting by Ilona Wissenbach, Writing by Miranda Murray; Editing by Jacqueline Wong)
