15 Multiple Levers to Drive Growth • Diverse client platform allows RMR to capitalize on strategic opportunities across sectors and navigate real estate cycles. • Significant opportunity to grow base business management fee (~$60 million) and incentive fees (2016 – 2019 annual average of ~$100 million) if Managed Equity REITs’ share prices continue to increase. • Leverage joint venture relationships to support future fundraising as we launch new ventures (e.g. credit, residential, industrial, etc.). • Expanding relationships with private capital creates cross-selling opportunities and could facilitate future allocations to new product launches and new real estate sectors. • Deploy balance sheet to seed and/or coinvest in private ventures, which could expand client relationships. • Identify possible strategic acquisition targets to accelerate AUM growth.

26 Definitions

27 Definitions • Assets Under Management (AUM) All references in this presentation to AUM on, or as of, a date are calculated at a point in time. • AUM is calculated as: (i) the historical cost of real estate and related assets, excluding depreciation, amortization, impairment charges or other non-cash reserves, of the Managed Equity REITs and certain Private Capital clients, plus (ii) the gross book value of real estate assets, property and equipment of AlerisLife, Sonesta and until May 15, 2023, TA, excluding depreciation, amortization, impairment charges or other non-cash reserves, plus (iii) the carrying value of loans held for investment and real estate owned by SEVN, plus (iv) the fair value of RMR Residential, both owned and third-party managed assets. Upon deconsolidation from a Managed Equity REIT, the respective real estate and related assets are characterized as Private Capital and their historical cost represents the fair value of the real estate at the time of deconsolidation. • Fee-Earning AUM is calculated (i) monthly for the Managed Equity REITs, based upon the lower of the average historical cost of each REIT's properties and its average market capitalization, plus (ii) for all other clients, Fee-Earning AUM equals AUM and includes amounts that may differ from the measures used for purposes of calculating fees under the terms of the respective management agreements. For additional information on the calculation of AUM for purposes of the fee provisions of the business management agreements, see RMR's Annual Report on Form 10-K for the fiscal year ended September 30, 2023, filed with the SEC. RMR's SEC filings are available at the SEC website: www.sec.gov. • Managed Equity REITs include Diversified Healthcare Trust (DHC), Industrial Logistics Properties Trust (ILPT), Office Properties Income Trust (OPI) and Service Properties Trust (SVC). • Mountain JV refers to Mountain Industrial REIT LLC, a joint venture in which ILPT owns a majority interest (and accordingly is presented in ILPT’s consolidated results). • Perpetual Capital refers to capital with an indefinite duration, which may be terminated under certain conditions, and includes the Managed Equity REITs, Seven Hills Realty Trust (SEVN), and until it was acquired by BP Products North America Inc. on May 15, 2023, TravelCenters of America Inc. (TA). • Private Capital consists of AlerisLife Inc. (AlerisLife), Sonesta International Hotels Corporation (Sonesta), residential real estate we manage from our acquisition of MPC Partnership Holdings LLC (RMR Residential) and other private capital vehicles including ABP Trust and other private entities that own commercial real estate. Some of the Managed Equity REITs own minority interests in certain of these entities. AlerisLife was a publicly traded company until March 20, 2023 when it was acquired by a subsidiary of ABP Trust. As a result, amounts for AlerisLife are characterized as Private Capital for all periods presented. Continued on next page.

28 Definitions (Continued) Non-GAAP Measures: RMR presents certain “non-GAAP financial measures” within the meaning of the applicable rules of the SEC, including EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin. The GAAP financial measure that is most directly comparable to EBITDA and Adjusted EBITDA is net income and the GAAP financial measure that is most directly comparable to Adjusted EBITDA Margin is Net Income Margin, which represents net income divided by total management and advisory services revenues. These non-GAAP financial measures do not represent net income, net income attributable to The RMR Group Inc. or cash generated by operating activities determined in accordance with GAAP, and should not be considered alternatives to net income, net income attributable to The RMR Group Inc. or net income margin determined in accordance with GAAP, as indicators of RMR’s financial performance or as measures of its liquidity. Other asset management businesses may calculate these non-GAAP measures differently than RMR does. Several non-GAAP measures are referenced in this presentation, including EBITDA, Adjusted EBITDA, Distributable Earnings and Adjusted EBITDA Margin. The RMR Group Inc. considers EBITDA, Adjusted EBITDA, Distributable Earnings and Adjusted EBITDA Margin to be appropriate supplemental measures of its operating performance, along with net income, net income attributable to The RMR Group Inc. and net income margin. These measures should be considered in conjunction with net income and net income attributable to The RMR Group Inc. as presented in The RMR Group Inc.’s consolidated statements of income. • EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are supplemental measures used to assess operating performance, along with net income, net income attributable to The RMR Group Inc. and net income margin. RMR believes that EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin provide useful information to investors because by excluding the effects of certain amounts, such as non-cash items or non-recurring gains and losses, EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin may facilitate a comparison of current operating performance with RMR’s historical operating performance and with the performance of other asset management businesses. RMR also believes that providing Adjusted EBITDA Margin may help investors assess RMR’s performance of its business by providing the margin that Adjusted EBITDA represents to its contractual management and advisory fees (excluding incentive business management fees, if any). Termination Fee Calculation: The $1.6 billion total estimated termination fee is the sum of the termination fees calculated under each of the applicable business and property management agreements based on the following assumptions: (a) assumed termination date of September 30, 2023; (b) for the Managed Equity REITs, monthly future fees were based on actual fees earned by RMR over the 12 months preceding the assumed termination date divided by twelve and, for purposes of determining present value, the monthly future fees were discounted using a rate equal to 1/12th of the sum of the applicable Treasury Rate for that future month plus 300bps. Additionally, in the event the management agreement is terminated by SEVN without a cause event or by Tremont Realty Capital LLC for a material breach, SEVN will be required to pay Tremont Realty Capital LLC a termination fee equal to (a) three times the sum of (i) the average annual base management fee and (ii) the average annual incentive fee, in each case paid or payable to Tremont Realty Capital LLC during the 24 month period immediately preceding the most recently completed calendar quarter prior to the date of termination or, if such termination occurs within 24 months of its initial commencement, the base management fee and the incentive fee will be annualized for such two year period based on such fees earned by Tremont Realty Capital LLC during such period, plus (b) $1.6 million. In addition, the initial organizational costs related to Tremont Mortgage Trust's formation and the costs of its initial public offering and the concurrent private placement that Tremont Mortgage Trust had paid pursuant to its management agreement with Tremont Realty Capital LLC will be included in the “Termination Fee” under and as defined in SEVN’s management agreement with Tremont Realty Capital LLC. No termination fee will be payable if the management agreement is terminated by SEVN for a cause event or by Tremont Realty Capital LLC without SEVN’s material breach. The estimated termination fee is presented for illustrative purposes only based on the assumptions described. Any actual termination fee may be higher or lower than the estimate depending on the actual calculation at the time, including then applicable fees, the then applicable discount rate and other factors.
