These measures should not be considered in isolation or as a substitute for measures of performance in accordance with U.S. GAAP. EBITDA, EBITDAre, Adjusted EBITDA, Hotel EBITDA, Hotel Adjusted EBITDA, FFO and Adjusted FFO, as calculated by us, may not be comparable to other companies that do not define such terms exactly as the Company. A detailed explanation of these non-GAAP financial measures and the reconciliation of such measures to the most directly comparable financial measures prepared in accordance with U.S. GAAP can be found in the Company’s second quarter 2023 earnings press release dated August 3, 2023.
