Positioned for Growth

11 Multiple Levers to Drive Growth Lever Support Managed REITs Enterprise Value Growth • Managed REIT Enterprise Value growth drives higher base management fees. The current potential upside from narrowing the gap between EV and historical cost of Managed REIT assets is an approximate $57 million annual revenue opportunity. • Share price appreciation supports incentive fee upside (2016 – 2019 annual average of ~$100 million). Expand Private Capital Vehicles • Leverage joint venture relationships to support future fundraising as RMR launches new ventures (credit, residential, industrial, development, etc.). • Expanding relationships with private capital creates cross-selling opportunities and could facilitate future allocations to new product launches and new real estate sectors. Utilize RMR’s Balance Sheet • Deploy balance sheet capital to seed and/or coinvest in private ventures, which could expand client relationships. • Identify possible strategic acquisition targets to accelerate AUM growth and expand institutional capital relationships.

Definitions

27 RMR presents certain “non-GAAP financial measures” within the meaning of the applicable rules of the SEC, including Adjusted Net Income Attributable to The RMR Group Inc., Adjusted Net Income Attributable to The RMR Group Inc. per diluted share, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin and Distributable Earnings. The GAAP financial measure that is most directly comparable to Adjusted Net Income Attributable to The RMR Group Inc. is net income attributable to The RMR Group Inc. The GAAP financial measure that is most directly comparable to Adjusted Net Income Attributable to The RMR Group Inc. per diluted share is net income attributable to The RMR Group Inc. per diluted share. The GAAP financial measure that is most directly comparable to EBITDA, Adjusted EBITDA and Distributable Earnings 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 revenues, excluding reimbursable costs. These non-GAAP financial measures do not represent net income, net income attributable to The RMR Group Inc., net income attributable to The RMR Group Inc. per diluted share 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., net income attributable to The RMR Group Inc. per diluted share 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. • Adjusted Net Income Attributable to The RMR Group Inc. RMR calculates Adjusted Net Income Attributable to The RMR Group Inc. and Adjusted Net Income Attributable to The RMR Group Inc. per diluted share as net income attributable to The RMR Group Inc. and net income attributable to The RMR Group Inc. per diluted share, respectively, excluding the effects of certain individually significant items occurring or impacting its financial results during the quarter that are not expected to be regularly occurring, relate to a special project or initiatives or relate to gains or losses. RMR provides Adjusted Net Income Attributable to The RMR Group Inc. and Adjusted Net Income Attributable to The RMR Group Inc. per diluted share for supplemental informational purposes in order to enhance the understanding of RMR’s condensed consolidated statements of income and to facilitate a comparison of RMR’s current operating performance with its historical operating performance. • Distributable Earnings is calculated as Adjusted EBITDA less tax distributions to members and is considered to be an appropriate measure of RMR’s operating performance, along with net income attributable to The RMR Group Inc. RMR believes that Distributable Earnings provides useful information to investors because by excluding amounts payable for tax obligations, it increases comparability between periods and more accurately reflects earnings that may be available for distribution to shareholders. Distributable Earnings is among the factors RMR’s Board of Directors considers when determining shareholder dividends. • Distributable Earnings per Share calculations are based on end of period shares outstanding and includes 15,000,000 Redeemable Class A Units of The RMR Group LLC which are paired with RMR Inc's. Class B-2 common shares outstanding; actual dividends are paid to shareholders as of the applicable record date. • Distribution Payout Ratio is calculated as distributions to shareholders from The RMR Group LLC divided by Distributable Earnings. • 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 or non-recurring items, 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 fees, if any). NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS

28 • 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 and Sonesta, 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 and wholly owned properties, 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, 2025, filed with the SEC. RMR's SEC filings are available at the SEC website: www.sec.gov. • GAAP refers to U.S. generally accepted accounting principles. • Managed Equity REITs refers to Diversified Healthcare Trust (DHC), Industrial Logistics Properties Trust (ILPT), Office Properties Income Trust (OPI) and Service Properties Trust (SVC). • Perpetual Capital refers to capital with an indefinite duration, which may be terminated under certain conditions, and includes the Managed Equity REITs and Seven Hills Realty Trust (SEVN). • Private Capital consists of AlerisLife Inc. (AlerisLife) through December 31, 2025, Sonesta International Hotels Corporation (Sonesta), residential real estate RMR manages through 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. As of December 31, 2025, AlerisLife ceased operations, was in the process of winding-down its operations, and transferred its management agreements with DHC for senior living communities to new operators. • Termination Fee Calculation: The $1.4 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 December 31, 2025; (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.

Disclaimer – Illustrative Valuation Analysis: Any information contained in this presentation about sum of the parts (SOTP) and illustrative valuations is "forward-looking" and utilizes hypothetical data and several management assumptions and estimates to provide an illustrative sum of the parts analysis and illustrative valuation estimates for RMR’s potential market valuation. It is important for readers to know that this illustrative analysis is not intended to be a prediction of the performance of RMR, its subsidiaries, affiliates or segments or its securities. Actual results could differ materially due to a variety of factors, including those discussed under “Risk Factors” in RMR’s periodic reports. In addition, a SOTP analysis is only one manner in which a company may be valued, and other parties may choose to value RMR differently. This illustrative analysis was internally prepared and there can be no assurance that any consensus value for RMR will be in line with this illustrative analysis (and any such consensus may be materially different). In addition, this illustrative analysis speaks only as of the date hereof. You are strongly encouraged to read RMR’s filings with the SEC for additional information about RMR and certain important risks and other factors that could affect RMR’s performance. You should not place undue reliance on forward-looking statements. Except as required by law, RMR does not intend to update or change any forward-looking statements as a result of new information, future events or otherwise.
