Portfolio Updates – Hotels: Sonesta Transition SVC will transfer the branding and management of 103 hotels to Sonesta from IHG, following IHG’s default in July 2020 and the subsequent termination of its management agreements with SVC. The effective date of the termination is November 30, 2020, which is the same date SVC currently plans to transfer the branding and management of the hotels to Sonesta. SVC owns approximately 34% of Sonesta and expects to indirectly share in the benefit of these new management agreements and in the hotels’ performance to the extent they ramp up in the post-pandemic recovery.

National Scale Sonesta International Hotels Corporation (“Sonesta”) is an owner, operator and franchisor of hotels under the Royal Sonesta, Sonesta and Sonesta ES Suites brands. Sonesta currently manages 15 full service hotels and 43 extended stay hotels in the United States and franchises or operates 22 hotels internationally. Similar Brand Characteristics SVC Further Benefits from Ownership Stake in Sonesta The 103 SVC owned hotels operated by IHG generally fit into Sonesta’s brand family with the InterContinental and Kimpton hotels becoming Royal Sonesta hotels, the Crowne Plaza and Holiday Inn hotels becoming Sonesta hotels and the Staybridge Suites and Candlewood Suites becoming Sonesta ES Suites extended stay hotels. SVC owns a 34% equity interest in Sonesta. In addition to benefitting from the post-COVID ramp-up of these hotels, SVC will benefit from a larger, more well-known Sonesta which will in turn also benefit SVC’s existing Sonesta-operated hotels. SVC should also experience hotel-level operating cost synergies related to Sonesta’s greater scale. Sonesta Is Benefitting from Changing Consumer Behavior The COVID-19 pandemic is causing changes in consumer behavior and expectations. During the second quarter, Sonesta’s extended stay portfolio outperformed its competitive set and gained significant market share. We believe that over the next several years, large, in-person group meetings may occur less frequently and as a result, business travelers may generate fewer rewards points, eroding the value of the guest affinity programs in driving business. Subsequently, guests may be more focused on their travel experience, safety and service, all areas where Sonesta more effectively competes with the major brands like IHG. Sonesta Has a Demonstrated Track Record of Operational Improvement Sonesta currently manages 16 hotels that were rebranded from IHG in 2012. Comparing pre-conversion stabilized performance to post-conversion stabilized performance, total hotel revenue and EBITDA increased 14.4% and 10.3%, respectively. Based on this historic experience, SVC believes the current portfolio of 103 hotels will perform as well or better as Sonesta branded and managed hotels post-conversion. Increased Flexibility With Sonesta as manager, SVC will have greater flexibility in terms of how closely it may asset manage these hotels and in executing on any decisions to repurpose or sell hotels that are not performing well relative to their required investment amount.

Non-GAAP Financial Measures: SVC presents certain “non-GAAP financial measures” within the meaning of applicable Securities and Exchange Commission, or SEC, rules, including EBITDA, EBITDAre, Adjusted EBITDAre, FFO and Normalized FFO. 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 its operating performance or as measures of its liquidity. These measures should be considered in conjunction with net income (loss) as presented in its condensed consolidated statements of income. 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. 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 19. EBITDAre is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or Nareit, which is EBITDA, excluding gains and losses on the sale of real estate, loss on impairment of real estate assets, if any, as well as certain other adjustments currently not applicable to SVC. In calculating Adjusted EBITDAre, SVC adjusts for the items shown on page 19 and include business management incentive fees only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. Other real estate companies and REITs may calculate EBITDA, EBITDAre and Adjusted EBITDAre differently than SVC. FFO and Normalized FFO: SVC calculates funds from operations, or FFO, and Normalized FFO as shown on page 20. FFO is calculated on the basis defined by Nareit, which is net income (loss), calculated in accordance with GAAP, excluding any gain or loss on sale of properties and loss on impairment of real estate assets, if any, plus real estate depreciation and amortization, less any unrealized gains and losses on equity securities, as well as certain other adjustments currently not applicable to us. In calculating Normalized FFO, SVC adjusts for the item shown on page 20 and include business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. FFO and Normalized FFO are among the factors considered by SVC's Board of Trustees when determining the amount of distributions to our shareholders. Other factors include, but are not limited to, requirements to maintain our qualification for taxation as a REIT, limitations in our credit agreement and public debt covenants, the availability to us of debt and equity capital, our distribution rate as a percentage of the trading price of SVC's common shares, or dividend yield, and to the dividend yield 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. Coverage: SVC defines hotel coverage as total hotel revenues minus all hotel expenses and FF&E reserve escrows that are not subordinated to minimum returns due to SVC divided by the minimum returns or rents due to SVC. Coverage amounts include operating data for certain hotels for periods prior to when SVC acquired them for periods they were managed by a different brand. SVC defines net lease coverage as earnings before interest, taxes, depreciation, amortization and rent, or EBITDAR, divided by the annual minimum rent due to us weighted by the minimum rent of the property to total minimum rents of the net lease portfolio. EBITDAR amounts used to determine rent coverage are generally for the latest twelve month period reported 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 us. Tenants that do not report operating information are excluded from the coverage calculations. Coverage amounts include data for certain properties for periods prior to when we acquired them. In instances where SVC does not have financial information for the most recent quarter from its tenants, SVC has calculated an implied EBITDAR for the second quarter using industry benchmark data to more accurately reflect the impact of COVID-19 on our tenants’ operations. SVC believes using only financial information from the earlier periods could be misleading as it would not reflect the negative impact those tenants experienced as a result of the COVID-19 pandemic. As a result, SVC believes using this industry benchmark data provides a more accurate estimated representation of recent operating results and coverage for those tenants. Investment: Represents historical cost of properties plus capital improvements funded by SVC less impairment writedowns, if any, and excludes capital improvements made from FF&E reserves funded from hotel operations which do not result in increases in minimum returns or rents. Net Debt: Represents total debt less cash and cash equivalents as of the date reported. SERVICE PROPERTIES TRUST (Nasdaq: SVC) | August 2020 2828

Alignment of Interests If SVC’s stock 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 historical cost of real estate. If total market cap is less than historical cost of real estate, base fee fluctuates with share price. Incentive fee structure keeps RMR focused on increasing total shareholder return. Members of RMR senior management and RMR are holders of SVC stock, RMR is 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 of $32 billion platform. •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 fee for RMR to complete any transaction that could reduce share price. RMR incentive fees contingent on total shareholder return(1) outperformance. •Equal to 12% of value generated by SVC in excess of the benchmark index total returns (SNL US Hotel REIT Index) per share over a three year period, subject to a cap (1.5% of equity market cap). •Absolute dollar outperformance must be positive to receive an incentive fee: it can’t be negative but better than the index. •Shareholders keep 100% of benchmark returns and 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 (excluding TA). (1) To determine final share price in SVC’s Total Return calculation, the business management agreement requires that the highest ten day share price average within the last 30 trading days of the measurement period be used. In the past, this and other less significant factors have resulted in differences between SNL’s calculation of SVC’s total return percentage and the total return percentage computed under the agreement.
