SERVICE PROPERTIES TRUST

Introduction to Unaudited Pro Forma Condensed Consolidated Financial Statements

On November 13, 2025, Service Properties Trust, or SVC, sold four hotels with a total of 459 keys located in three states for a combined sales price of $23.5 million, excluding closing costs, or the Last Closing, pursuant to a previously disclosed agreement that SVC entered into to sell, in phases, 45 hotels with a total of 5,997 keys for a combined sales price of $432.0 million, excluding closing costs, or the 45 Hotel Sale Portfolio. As previously reported on November 4, 2025, SVC sold a combined 18 hotels in the 45 Hotel Sale Portfolio with a total of 2,439 keys for a combined sales price of $183.0 million, excluding closing costs. SVC remains under agreement to sell the remaining 23 hotels with a total of 3,099 keys for a combined sales price of $225.5 million, excluding closing costs.

The following unaudited pro forma condensed consolidated balance sheet as of September 30, 2025 reflects SVC's financial position as if the sales of 10 hotels in the 45 Hotel Sale Portfolio sold from October 1, 2025 through November 13, 2025, were completed as of September 30, 2025. The following unaudited pro forma condensed consolidated statements of loss for the year ended December 31, 2024 and for the nine months ended September 30, 2025 reflect SVC's results of operations as if the 22 hotels in the 45 Hotel Sale Portfolio sold from January 1, 2025 through November 13, 2025 were completed on January 1, 2024. These unaudited pro forma condensed consolidated financial statements should be read in conjunction with (i) SVC's unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2025, and the notes thereto, included in SVC's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission, or the SEC, on November 5, 2025, and (ii) SVC's consolidated financial statements for the year ended December 31, 2024, and the notes thereto, included in SVC's Annual Report on Form 10-K filed with the SEC on February 26, 2025.

These unaudited pro forma condensed consolidated financial statements are provided for informational purposes only and are not necessarily indicative of SVC's expected financial position or results of operations for any future period. Differences could result from numerous factors, including future changes in SVC's portfolio of investments, capital structure, property level operating expenses and revenues, including returns received from SVC’s hotels or rents expected to be received pursuant to SVC's existing leases or leases SVC may enter into, changes in interest rates and other reasons. Actual future results are likely to be different from amounts presented in these unaudited pro forma condensed consolidated financial statements and such differences may be significant. In the opinion of management, all adjustments necessary to reflect, in all material respects, the effects of 22 hotels in the 45 Hotel Sale Portfolio sold from January 1, 2025 through November 13, 2025 have been included.
