On the development front, we opened another 595 hotels in the quarter, well on track of achieving our 2,300 gross opening target for the full year of 2025. We remain cautious on the near-term industry outlook given the macro uncertainties, rising supply, and relatively soft corporate travel demand. Nevertheless,we are positive on the long-term growth for China’s travel and hospitality industry. We will continue focusing on building our own core competencies, expanding our high-quality network, upgrading our supply chain, enhancing our brand positioning and 'service excellence', and strengthening our sales capabilities.”

“Regarding our business outside China, our Legacy-DH segment achieved an 8.1% year-over-year blended RevPAR increase in the second quarter of 2025, driven primarily by a 5.6 percentage-point increase in occupancy rate. We will continue to enhance our hotel operations, focus on cost reduction and efficiency improvement, and continue developing our asset-light portfolio.”

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 Reconciliation 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.
