H World Group Limited Announces Preliminary Results for Hotel Operations in the Fourth Quarter and the Full Year of 2023

Singapore/Shanghai, China, January 22, 2024 – H World Group Limited (NASDAQ: HTHT and HKEX: 1179) (“H World”, “we” or “our”), a key player in the global hotel industry, today announced preliminary results for hotel operations in the fourth quarter (“Q4 2023”) and the full year ended December 31, 2023.

Business update

For our Legacy-Huazhu business, our RevPAR in Q4 2023 recovered to 120% of the 2019 level, supported by the sustained recovery in both leisure and business travel demand. Breaking down into each month, our RevPAR in October, November and December 2023 recovered to 120%, 117% and 123% of the 2019 levels, respectively. For the full year of 2023, our RevPAR reached 122% of the 2019 level. While the RevPAR growth in 2023 was primarily driven by ADR, we also experienced continuous recovery in the occupancy rate. With respect to the network expansion, we opened 460 hotels and closed 225 hotels in Q4 2023. We recorded a net increase of 852 hotels to our network in the full year of 2023.

For Steigenberger Hotels GmbH and its subsidiaries (“DH”, or “Legacy-DH”), RevPAR in Q4 2023 recovered to 111% of the 2019 level, and was marginally above the 2022 level mainly due to a higher ADR base experienced during the FIFA World Cup and the COP27 UN Climate Change Conference in Q4 2022.
