Revenue in the first quarter of 2025 was RMB5.4 billion (US$744 million), representing a 2.2% year-over-year increase and a quarter-over-quarter decrease of 10.4%. Revenue from the Legacy-Huazhu segment in the first quarter of 2025 was RMB4.5 billion, representing a 5.5% year-over-year increase and a 6.4% quarter-over-quarter decline. The 5.5% year-over-year increase was mainly driven by continued hotel network expansion. Revenue from the Legacy-DH segment in the first quarter of 2025 was RMB918 million, representing an 11.3% year-over-year decrease and a 26.0% quarter-over-quarter decline.

Revenue from leased and owned hotels in the first quarter of 2025 was RMB2.8 billion (US$385 million), representing a 10.0% year-over-year decrease and a 17.3% quarter-over-quarter decline. Revenue from leased and owned hotels from the Legacy-Huazhu segment in the first quarter of 2025 was RMB1.9 billion, representing a 9.4% year-over-year decrease, as we continue exiting leased and owned hotels. Revenue from leased and owned hotels from the Legacy-DH segment in the first quarter of 2025 was RMB876 million, representing an 11.2% year-over-year decrease, as we exited 11 leased hotels.

Revenue from manachised and franchised hotels in the first quarter of 2025 was RMB2.5 billion (US$344 million), representing a 21.1% year-over-year increase and remaining flat from quarter-over-quarter. Revenue from our Legacy-Huazhu segment from manachised and franchised hotels in the first quarter of 2025 was RMB2.5 billion, representing a 21.1% year-over-year increase, driven by hotel network expansion. Revenue from manachised and franchised hotels from the Legacy-DH segment in the first quarter of 2025 was RMB31 million, representing a 34.8% year-over-year increase, as we transformed 10 leased hotels to manachised and franchised hotels.

Other revenue represents revenue generated from businesses other than our hotel operations, which mainly includes revenue from the provision of IT products, and services and Huazhu Mall™ and other revenue from the Legacy-DH segment, totaling RMB107 million (US$15 million) in the first quarter of 2025, compared to RMB116 million in the first quarter of 2024 and RMB151 million in the previous quarter.

Hotel operating costs in the first quarter of 2025 were RMB3.6 billion (US$497 million), reflecting a 1.1% year-over-year increase. The 1.1% year-over-year increase was mainly due to a 4.2% year-over-year increase in Legacy-Huazhu and partially offset by a 7.2% year-over-year decline in Legacy-DH. As we continue to pursue an asset-light strategy, our hotel operating costs as a percentage of revenue have decreased by 0.7 percentage points year-over-year.

Selling, General and administrative expenses (SG&A) in the first quarter of 2025 were RMB755 million (US$104 million), reflecting a 1.8% year-over-year decrease, with an 11.1% year-over-year decline in Legacy-DH thanks to our restructuring and cost optimization effort and partially offset by a 1.6% year-over-year increase in Legacy-Huazhu due mainly to an increase in share-based compensation (SBC).

Other operating income, net in the first quarter of 2025 was RMB60 million (US$8 million), compared to RMB76 million in the first quarter of 2024 and RMB99 million in the previous quarter.

Income from operations in the first quarter of 2025 was RMB1.1 billion (US$149 million), reflecting a 7.9% year-over-year increase, and mainly driven by an 8.1% year-over-year increase in Legacy-Huazhu and partially offset by a 9.4% year-over-year decline in Legacy-DH.

Operating margin, defined as income from operations as a percentage of revenue, was 20.1% in the first quarter of 2025, compared with 19.0% in the first quarter of 2024 and 15.0% in the previous quarter. The margin improvement was mainly due to a higher revenue contribution from our manachised and franchised business. This was in line with our asset-light expansion strategy.

Other income, net in the first quarter of 2025 was an income of RMB22 million (US$3 million), compared to an income of RMB40 million in the first quarter of 2024 and an expense of RMB14 million in the previous quarter.

Gains (losses) from fair value changes of equity securities in the first quarter of 2025 were losses of RMB12 million (US$2 million), compared to gains of RMB38 million in the first quarter of 2024, and losses of RMB19 million in the previous quarter. Gains (losses) from fair value changes of equity securities mainly represent the gains (losses) from our investments in equity securities with readily determinable fair values.

Income tax expense in the first quarter of 2025 was RMB377 million (US$52 million), compared to RMB279 million in the first quarter of 2024 and RMB578 million in the previous quarter. The higher income tax expense in the quarter was due to withholding tax related to dividend distributions.

Net income attributable to H World Group Limited in the first quarter of 2025 was RMB894 million (US$123 million), reflecting a 35.7% year-over-year increase, mainly supported by a 27.2% year-over-year increase in Legacy-Huazhu.

EBITDA (non-GAAP) in the first quarter of 2025 was RMB1.6 billion (US$222 million), compared with RMB1.3 billion in the first quarter of 2024 and RMB974 million in the previous quarter.

Adjusted EBITDA, which excluded the following from EBITDA (non-GAAP): share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments, was RMB1.5 billion (US$206 million) in the first quarter of 2025, compared with RMB1.4 billion in the first quarter of 2024 and RMB1.2 billion in the previous quarter. Adjusted EBITDA from the Legacy-Huazhu segment, which is a segment measure, was RMB1.6 billion in the first quarter of 2025, compared with RMB1.5 billion in the first quarter of 2024 and RMB1.5 billion in the previous quarter.

Use of Non-GAAP Financial Measures

To supplement the Company’s unaudited consolidated financial results presented in accordance with U.S. Generally-Accepted Accounting Principles (“GAAP”), the Company uses the following non-GAAP measures defined as non-GAAP financial measures by the U.S. Securities and Exchange Commission (“SEC”): adjusted net income (loss) attributable to H World Group Limited excluding share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments; adjusted basic and diluted earnings (losses) per share/ADS excluding share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments; EBITDA; adjusted EBITDA excluding share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP. For more information on these non-GAAP financial measures, please see the table captioned “Unaudited Reconciliations of GAAP and non-GAAP Results” set forth at the end of this release. The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding Company performance by excluding share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments that may not be indicative of Company operating performance. The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing Company performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to the Company’s historical performance. The Company believes these non-GAAP financial measures are also useful to investors in allowing for greater transparency with respect to supplemental information used regularly by Company management in financial and operational decision-making. A limitation of using non-GAAP financial measures excluding share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments is that share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments have been and may continue to be significant and recurring in the Company’s business. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying tables have more details on the reconciliations between GAAP financial measures that are most directly comparable to non-GAAP financial measures.

The Company believes that EBITDA is a useful financial metric to assess the operating and financial performance before the impact of investing and financing transactions and income taxes, given the significant investments that the Company has made in leasehold improvements, depreciation and amortization expense that comprise a significant portion of the Company’s cost structure. In addition, the Company believes that EBITDA is widely used by other companies in the lodging industry and may be used by investors as a measure of financial performance. The Company believes that EBITDA information provides investors with a useful tool for comparability between periods because it excludes depreciation and amortization expense attributable to capital expenditures. The Company also uses adjusted EBITDA to assess operating results of its hotels in operation. The Company believes that the exclusion of share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments helps facilitate year-over-year comparisons of the results of operations as the share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments may not be indicative of Company operating performance.

Therefore, the Company believes adjusted EBITDA more closely reflects the financial performance capability of our hotels. The presentation of EBITDA and adjusted EBITDA should not be construed as an indication that the Company’s future results will be unaffected by other charges and gains considered to be outside the ordinary course of business.

The use of EBITDA and adjusted EBITDA has certain limitations. Depreciation and amortization expense for various long-term assets (including land use rights), income tax, interest expense and interest income have been and will be incurred and are not reflected in the presentation of EBITDA. Share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments have been and will be incurred and are not reflected in the presentation of adjusted EBITDA. Each of these items should also be considered in the overall evaluation of the results. The Company compensates for these limitations by providing the relevant disclosure of depreciation and amortization, interest income, interest expense, income tax expense, share-based compensation expenses, gain (loss) from fair value changes of equity securities, foreign exchange gain (loss), net, and gain (loss) on disposal of investments all in the reconciliations to the U.S. GAAP financial measures and in the consolidated financial statements, all of which should be considered when evaluating the performance of the Company.

The terms EBITDA and adjusted EBITDA are not defined under U.S. GAAP, and neither EBITDA nor adjusted EBITDA is a measure of net income, operating income, operating performance or liquidity presented in accordance with U.S. GAAP. When assessing the operating and financial performance, investors should not consider these data in isolation or as a substitute for the Company’s net income, operating income or any other operating performance measure that is calculated in accordance with U.S. GAAP. In addition, the Company’s EBITDA or adjusted EBITDA may not be comparable to EBITDA or adjusted EBITDA or similarly titled measures utilized by other companies since such other companies may not calculate EBITDA or adjusted EBITDA in the same manner as the Company does.

Reconciliations of the Company’s non-GAAP financial measures, including EBITDA and adjusted EBITDA, to the consolidated statement of operations information are included at the end of this press release.
