FORWARD LOOKING STATEMENTS & USE OF NON-GAAP FINANCIAL MEASURES 2 FORWARD LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of federal securities laws and regulations. These forward-looking statements are identified by their use of terms and phrases such as "believe," "expect," "intend," "project," "forecast," "plan" and other similar terms and phrases, including references to assumptions and forecasts of future results. Forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors which may cause the actual results to differ materially from those anticipated at the time the forward-looking statements are made. These risks include, but are not limited to: the adverse impact of any future pandemic, epidemic or outbreak of any highly infectious disease on the U.S., regional and global economies, travel, the hospitality industry, and the financial condition and results of operations of the Company and its hotels; negative developments or volatility in the economy, including, but not limited to elevated inflation and interest rates, job loss or growth trends, the imposition of trade sanctions or tariffs and any potential retaliatory responses thereto, an increase in unemployment or a decrease in corporate earnings and investment; risks associated with the lodging industry overall, including, without limitation, decreases in the frequency of travel, decreases in the demand for, or frequency of, international travel as a result of evolving global trade dynamics or otherwise, and increases in operating costs; relationships with property managers; the ability to compete effectively in areas such as access, location, quality of accommodations and room rate structures; changes in taxes and government regulations which influence or determine wages, prices, construction procedures and costs; and other risk factors contained in the Company's filings with the Securities and Exchange Commission. Although the Company believes the expectations reflected in such forward- looking statements are based upon reasonable assumptions, it can give no assurance that the expectations will be attained or that any deviation will not be material. All information in this presentation is as of the date of this presentation, and the Company undertakes no obligation to update any forward-looking statement to conform the statement to actual results or changes in the Company's expectations. This presentation contains statistics and other data that has been obtained or compiled from information made available by third-party service providers and believed to be reliable, but the accuracy and completeness of the information is not assured. The Company has not independently verified any such information. USE OF NON-GAAP FINANCIAL MEASURES We use the following non-GAAP financial measures that we believe are useful to investors as key measures of our operating performance: EBITDA, EBITDAre, Adjusted EBITDA, Hotel Adjusted EBITDA, FFO and Adjusted FFO. We also present Comparable Total Revenue, Comparable Room Revenues, Comparable Hotel Adjusted EBITDA and Comparable Hotel Adjusted EBITDA Margin. 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 Adjusted EBITDA, FFO, Adjusted FFO, Comparable Total Revenue, Comparable Room Revenues, Comparable Hotel Adjusted EBITDA and Comparable Hotel Adjusted EBITDA Margin, 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 first quarter 2026 earnings press release dated April 30, 2026.
