Fees that SVC Pays to RMR are Primarily Performance Based which Aligns Interests with Shareholders RMR base management fee tied to SVC’s share price performance. • Consists of an annual fee equal to generally 50 bps multiplied by the lower of: (1) SVC’s historical cost of real estate, or (2) SVC’s total market capitalization. • There is no incentive for RMR to complete any transaction that could reduce share price. RMR incentive fees contingent on total shareholder return outperformance. • Incentive management fee: 12% of the outperformance of SVC’s total return per share compared to the MSCI U.S. REIT/Hotel & Resort Index over a three year period multiplied by equity market capitalization. • Outperformance must be positive to be earned. • Shareholders keep 100% of benchmark returns and at least 88% of returns in excess of the benchmark. Other fees. • Property management fee: consists of an annual fee based on 3.0% of rents collected at SVC’s managed retail net lease properties. Alignment of Interests If SVC’s share price goes up and its total market cap exceeds its historical cost of real estate, RMR base management fee is capped at 50 bps of SVC’s historical cost of real estate. If SVC’s stock price goes down and its historical cost of real estate exceeds its total market cap, RMR gets less base management fees (50 bps on equity market cap plus debt). Incentive fee structure keeps RMR focused on increasing total shareholder return. Members of RMR senior management are holders of SVC common shares, some subject to long term lock up agreements. SVC shareholders have visibility into RMR, a publicly traded company. SVC benefits from RMR’s national footprint and economies of scale from a platform with approximately $40 billion in AUM. 27

Notes to Calculations of FFO, Normalized FFO, CAD, EBITDA, EBITDAre, Adjusted EBITDAre, Hotel EBITDA and Adjusted Hotel EBITDA 1. As of March 31, 2025, SVC owned 202 hotels. SVC's condensed consolidated statements of income (loss) include hotel operating revenues and expenses of its managed hotels. 2. When managers of SVC's hotels are required to fund the shortfalls of owner's priority return under the terms of the management agreements or their guarantees, SVC reflects such fundings in its condensed consolidated statements of income (loss) as a reduction of hotel operating expenses. When these shortfalls are replenished by cash flows from the applicable hotel operations in excess of the owner's priority return due, SVC reflects such replenishment in its condensed consolidated statements of income (loss) as an increase to hotel operating expenses. The net decrease to hotel operating expenses was $3,412 and $522 for the three months ended March 31, 2025 and 2024, respectively. 3. Transaction related costs for the three months ended March 31, 2025 of $111 primarily consist of costs related to the renovation of certain hotels, partially offset by the recovery of a working capital reserve related to SVC’s former agreement with Marriott International, Inc. previously deemed uncollectable and expensed in 2021. 4. SVC recorded a net loss on asset impairment for the three months ended March 31, 2025 of $37,067 to reduce the carrying value of 16 hotels to their estimated fair value less costs to sell. SVC recorded a net loss on asset impairment for the three months ended March 31, 2024 of $2,451 to reduce the carrying value of five net lease properties to their estimated fair value less costs to sell. 5. SVC recorded a net gain on sale of real estate for the three months ended March 31, 2025 of $746 in connection with the sales of four hotels and three net lease properties. SVC recorded a net loss on sale of real estate for the three months ended March 31, 2024 of $2,963 in connection with the sales of one hotel and three net lease properties. 6. SVC is amortizing a liability it recorded for the fair value of its initial investment in Sonesta as a reduction to hotel operating expenses in the condensed consolidated statements of income (loss). SVC reduced hotel operating expenses by $621 for each of the three months ended March 31, 2025 and 2024, related to this liability. 31

Non-GAAP Financial Measures and Certain Definitions 32 Non-GAAP Financial Measures SVC presents certain “non-GAAP financial measures” within the meaning of the applicable SEC rules, including FFO, Normalized FFO, CAD, EBITDA, Hotel EBITDA, Adjusted Hotel EBITDA, EBITDAre and Adjusted EBITDAre. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income (loss) as indicators of SVC's operating performance or as measures of its liquidity. These measures should be considered in conjunction with net income (loss) as presented in SVC’s condensed consolidated statements of income (loss). SVC considers these non-GAAP measures to be appropriate supplemental measures of operating performance for a REIT, along with net income (loss). SVC believes these measures provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation and amortization expense, they may facilitate a comparison of its operating performance between periods and with other REITs and, in the case of Hotel EBITDA and Adjusted Hotel EBITDA, reflecting only those income and expense items that are generated and incurred at the hotel level may help both investors and management to understand the operations of its hotels. FFO and Normalized FFO: SVC calculates funds from operations, or FFO, and normalized funds from operations, or Normalized FFO, as shown on page 28. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or Nareit, which is net income (loss), calculated in accordance with GAAP, excluding any gain or loss on sale of real estate and loss on impairment of real estate assets, if any, plus real estate depreciation and amortization, as well as adjustments to reflect SVC's share of FFO attributable to an investee and certain other adjustments currently not applicable to SVC. In calculating Normalized FFO, SVC adjusts for the items shown on page 28. FFO and Normalized FFO are among the factors considered by SVC's Board of Trustees when determining the amount of distributions to SVC's shareholders. Other factors include, but are not limited to, requirements to satisfy SVC’s REIT distribution requirements, limitations in its debt agreements, the availability to SVC of debt and equity capital, SVC's distribution rate as a percentage of the trading price of its common shares, or dividend yield, and SVC’s dividend yield compared to the dividend yields of other REITs, SVC's expectation of its future capital requirements and operating performance and its expected needs for and availability of cash to pay its obligations. Other real estate companies and REITs may calculate FFO and Normalized FFO differently than SVC does. Cash Available for Distribution: SVC calculates cash available for distribution, or CAD, as shown on page 28. SVC defines CAD as Normalized FFO minus SVC’s proportionate share of Normalized FFO from its equity method investment, plus operating cash flow distributions from its equity method investment, if any, less real estate related capital expenditures and adjusted for other non-cash and nonrecurring items. CAD is among the factors considered by SVC's Board of Trustees when determining the amount of distributions to SVC's shareholders. Other real estate companies and REITs may calculate CAD differently than SVC does. EBITDA, EBITDAre and Adjusted EBITDAre: SVC calculates earnings before interest, taxes, depreciation and amortization, or EBITDA, EBITDA for real estate, or EBITDAre, and Adjusted EBITDAre as shown on page 29. EBITDAre is calculated on the basis defined by Nareit, which is EBITDA, excluding gains and losses on the sale of real estate, loss on impairment of real estate assets, if any, and adjustments to reflect SVC's share of EBITDAre attributable to an investee. In calculating Adjusted EBITDAre, SVC adjusts for the items shown on page 29. Other real estate companies and REITs may calculate EBITDA, EBITDAre and Adjusted EBITDAre differently than SVC does. Hotel EBITDA and Adjusted Hotel EBITDA: SVC calculates Hotel EBITDA as hotel operating revenues less hotel operating expenses of all managed and leased hotels, prior to any adjustments required for presentation in its condensed consolidated statements of income (loss) in accordance with GAAP. Adjusted Hotel EBITDA excludes certain items SVC believes do not reflect the ongoing operating performance of SVC’s hotels. SVC believes that Hotel EBITDA and Adjusted Hotel EBITDA provide useful information to management and investors as a key measure of the profitability of its hotel operations.

Non-GAAP Financial Measures and Certain Definitions (Continued) 33 Other Definitions Annualized Minimum Rent: Generally, SVC's lease agreements with its net lease tenants require payment of minimum rent to SVC. Certain of these minimum rent payment amounts are secured by full or limited guarantees. Annualized minimum rent represents cash amounts and excludes adjustments, if any, necessary to record scheduled rent changes on a straight line basis or any expense reimbursements. Annualized minimum rent for TA excludes the impact of rents prepaid by TA. Adjusted Hotel EBITDA Margin: Adjusted Hotel EBITDA as a percentage of hotel operating revenues. Average Daily Rate: ADR represents rooms revenue divided by the total number of room nights sold in a given period. ADR provides useful insight on pricing at SVC's hotels and is a measure widely used in the hotel industry. Chain Scale: As characterized by STR Global Limited, a data benchmark and analytics provider for the lodging industry. Comparable Hotels Data: SVC presents RevPAR, ADR and occupancy for the periods presented on a comparable basis to facilitate comparisons between periods. SVC defines comparable hotels as those that it owned on March 31, 2025 and were open and operating for the entirety of the periods being compared. For each of the three months ended March 31, 2025 and 2024, SVC's comparable results exclude one hotel that suspended operations during the periods presented. Debt: Debt amounts reflect the principal balance as of the date reported. Net debt means total debt less unrestricted cash and cash equivalents as of the date reported. Exit Hotels: Exit Hotels represent 118 hotels managed by Sonesta and one hotel managed by InterContinental Hotels Group, plc that SVC plans to sell. FF&E Reserves: FF&E Reserves, or FF&E Reserves from managed hotel operations, represent various percentages of total sales at certain of SVC's hotels that are escrowed as reserves for future renovations or refurbishments, or FF&E Reserve escrows. SVC owns all the FF&E Reserve escrows for its hotels. GAAP: GAAP is U.S. generally accepted accounting principals. General and Administrative Expense Paid in Common Shares: Amounts represent the equity compensation for SVC’s Trustees, officers and certain other officers and employees of RMR. Gross Book Value of Real Estate Assets: Gross book value of real estate assets is real estate properties at cost plus acquisition related costs, if any, before purchase price allocations, less impairment write-downs, if any. Investment: SVC defines hotel investment as historical cost of its properties plus capital improvements funded by it less impairment write-downs, if any, and excludes capital improvements made from FF&E Reserves funded from hotel operations that do not result in increases in owner’s priority return or rents. SVC defines net lease investment as historical cost of its properties plus capital improvements funded by SVC less impairment write-downs, if any.

Non-GAAP Financial Measures and Certain Definitions (Continued) 34 Occupancy: Occupancy represents the total number of room nights sold divided by the total number of room nights available at a hotel or group of hotels and represents occupied properties as of the end of the period shown for net lease properties. Occupancy is an important measure of the utilization rate and demand of SVC's properties. Non-Cash Expenses: Non-cash expenses represent general and administrative expense paid in common shares and amortization of liabilities relating to SVC’s initial investment in Sonesta and its former investment in The RMR Group, Inc. Non-Cash Interest Expense: Non-cash interest expense represents amortization of debt issuance costs, discounts and premiums. Non-Cash Revenues: Non-cash revenues represent straight-line rent adjustments, lease value amortization, FF&E Reserves, including interest income earned, and the impact of rents prepaid by TA. Owner's Priority Return: Each of its management agreements or leases with hotel operators provides for payment to SVC of an annual owner’s priority return or minimum rent, respectively. Certain of these minimum payment amounts are secured by full or limited guarantees. In addition, certain of its hotel management agreements provide for payment to SVC of additional amounts to the extent of available cash flows as defined in the management agreement. Payments of these additional amounts are not guaranteed. Rent Coverage: SVC defines rent coverage as earnings before interest, taxes, depreciation, amortization and rent, or EBITDAR, divided by the annual minimum rent due to SVC weighted by the minimum rent of the property to total minimum rents of the net lease portfolio. Tenants with no minimum rent required under the lease are excluded. EBITDAR amounts used to determine rent coverage are generally for the latest twelve month period, based on the most recent operating information, if any, furnished by the tenant. Operating statements furnished by the tenant often are unaudited and, in certain cases, may not have been prepared in accordance with GAAP and are not independently verified by SVC. In instances where SVC does not have tenant financial information, it calculates an implied coverage ratio for the period based on other tenants with available financial statements operating the same brand or within the same industry. As a result, SVC believes using this implied coverage metric provides a more reasonable estimated representation of recent operating results and the financial condition for those tenants. Retained Hotels: Retained Hotels represents 59 hotels managed by Sonesta, 17 hotels managed by Hyatt Hotels Corporation, and seven hotels managed by Radisson Hospitality, Inc. that SVC will continue to own after the Exit Hotels are sold. Revenue per Available Room: RevPAR represents rooms revenue divided by the total number of room nights available to guests for a given period. RevPAR is an industry metric correlated to occupancy and ADR and helps measure revenue performance over comparable periods. SOFR: SOFR is the secured overnight financing rate. Total Gross Assets: Total gross assets is total assets plus accumulated depreciation. Weighted Average Lease Term: Weighted average lease term represents the average lease term in years weighted on annualized minimum rent.
