LETTER TO OUR SHAREHOLDERS FROM YOUR BOARD OF DIRECTORS

![[MISSING IMAGE: ph_letter-4c.jpg]](ph_letter-4c.jpg) <br>

Dear Fellow Shareholders:

Please join us for our 2026 Annual Meeting of Shareholders, which will be held virtually at 9:30 a.m. on Thursday, March 26, 2026. The business to be conducted at the meeting is described in the attached Notice of Meeting and Proxy Statement. We believe furnishing these materials to shareholders electronically expedites your receipt, while lowering costs and reducing environmental impact.

We remain focused on executing our long-term business strategies to enhance growth at our perpetual capital clients and advance our private capital fundraising and investment initiatives. During 2025, we took various actions to strengthen our managed REITs' balance sheets, executing over $3.9 billion of debt financings and over $900 million of asset sales, the proceeds of which our clients' primarily used to repay maturing debts. Additionally, we completed nearly eight million square feet of leasing for our managed REITs at rental rates that were approximately 14% higher than prior rents for the same space, laying the foundation for future revenue growth.

Within our private capital business, we advanced strategies on multiple fronts. As general partner in joint venture arrangements, we completed the acquisition of two residential communities totaling nearly $200 million. We launched fundraising initiatives for RMR Residential's new Enhanced Growth Venture with initial seed investments in apartment communities totaling over $400 million. Additionally, we acquired a community shopping center for $21 million in suburban Chicago as part of our new strategy to build a portfolio of value-add, multi-tenant retail properties for future fundraising opportunities. At the end of the fiscal year, our total assets under management (AUM) were approximately $39 billion, including over $12 billion in private capital AUM, which we have built in less than five years' time.

We continue to invest in our people, technology and brand. Over the past year, we reinforced our leadership team with the promotions of Matt Jordan to Chief Operating Officer and Matt Brown to Chief Financial Officer. We also made strategic investments in artificial intelligence to help drive operational efficiencies and unlock new capabilities. In addition, we recruited private capital formation and investor relations senior leaders to fortify our position in the various competitive environments where we and our clients operate.

We remain confident in our strategic vision and ability to create lasting value through disciplined oversight, financial strength and private capital growth. We appreciate your continued investment and your confidence in our stewardship of your capital.

CORPORATE GOVERNANCE PRINCIPLES AND BOARD MATTERS

### Board Composition
We are currently governed by a six member Board of Directors.

We understand the importance of leading a sustainable business and regularly consider ways to improve our internal culture and the communities in which we operate. Our annual sustainability report can be found at https://www.rmrgroup.com/corporate-sustainability. In this "Sustainability" section, unless the context requires otherwise, references to "we," "us" and "our" refer to The RMR Group Inc. and The RMR Group LLC ("RMR LLC"). Highlights of our sustainability strategies are as follows:

**Environmental.** We recognize our responsibility to minimize the impact of our business on the environment. We seek to preserve natural resources and maximize efficiencies in order to reduce the negative impact the properties we own and manage have on the planet. Our environmental sustainability strategies and best practices help to mitigate our managed properties' environmental footprint, optimize operational efficiency and enhance our competitiveness in the marketplace.

We remain committed to our "Zero Emissions Promise" announced in 2022 to reduce scope 1 and 2 greenhouse gas (GHG) emissions 50% per square foot of managed property by 2029 from a 2019 base year and to scope 1 and 2 carbon neutrality by 2050. Our 50% reduction target has now been validated by the Science Based Targets initiative (SBTi) and is in line with a well-below 2°C (WB2C°) trajectory. Following the acquisition of our residential platform in December 2023, we incorporated scope 1 and 2 GHG emissions per square foot of managed common area at residential properties into our emissions reduction commitment. We anticipate emissions reductions will occur through a combination of strategic capital investments in energy efficiency by applicable clients, stakeholder engagement to promote sustainable behavior, the deployment of onsite solar and other renewable energy technologies, and the purchase of energy from

renewable sources. We believe our efforts toward these goals will add value to our and our clients' properties, benefit tenants by lowering their operating costs, drive sustainable economic returns and address investor demands that our clients have viable strategies to mitigate climate risk. We have made significant progress to date, achieving an overall reduction in emissions and energy of 30.5% and 20.5%, respectively.

We have incorporated specific sustainability objectives into our overall business strategy and portfolio management through the following programs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Climate scenario analyses performed across multiple time horizons and multiple potential future global emissions levels.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Engage with tenant stakeholders on common sustainability goals to promote environmental performance alignment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Environmental surveys are conducted prior to acquiring a property.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Environmental safety checklists at the property level are reviewed quarterly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Environmental safety training for engineers is conducted annually.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Waste programs include diversion, rightsizing, education and expense management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Environmental-friendly cleaning and pest control support indoor environmental quality.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Real-time energy monitoring, fault detection & diagnostics, energy and water audits and energy conservation best practices meetings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Assess asset-level compliance with current and future building energy and emissions performance standards across the United States and establish cost-effective pathways to comply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Green and energy-efficient equipment purchasing guideline which mandates the use of high energy efficiency equipment and environmentally friendly materials for new developments and major asset refurbishments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Number of ENERGY STAR<sup>®</sup> and Leadership in Energy and Environmental Design ("LEED<sup>®</sup>") certified buildings continue to increase each year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Energy costs managed through supply contracts in deregulated energy markets.

We received the ENERGY STAR<sup>®</sup> Partner of the Year Award in 2024 for the sixth time and for a fourth year with a Sustained Excellence designation for our outstanding efforts in Energy Management in executing ENERGY STAR<sup>®</sup> related activities at buildings we manage on behalf of our clients. In 2022, we earned LEED<sup>®</sup> Proven Provider™ recognition from the US Green Building Council for demonstrating successful and consistent performance in the LEED Project Administrator role and the Fitwel Viral Response Certification with Distinction for our operational policies that mitigate the spread of infectious respiratory diseases. Our Environmental Policy can be found on our website.

**Human Capital.** We believe the foundation of our success begins with ensuring our employees have the opportunity to participate in first-in-class benefits programs and competitive salaries. Our strength lies in the collective experience of our employees, which also drives individual and group performance that benefits us and our clients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **Employees and Equal Opportunity.** As of September 30, 2025, we employed approximately 860 real estate professionals, including 36% in our corporate office and 64% across our more than 30 offices throughout the United States.

Within their first year, our managers complete the workshop and learn how to effectively delegate, solve problems and give meaningful performance feedback.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ◦ *Tuition Reimbursement Program:* We offer tuition assistance up to $20,000 annually for work-related education from accredited colleges and universities in order to deepen employees' skillsets and support personal enrichment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ◦ *RMR Internship Programs:* We offer hands-on experience across a wide array of disciplines that are critical to the success of our organization. Interns have the opportunity to contribute to and learn from teams operating within our accounting, asset management, real estate development, energy and sustainability, information technology, investor relations and human resources departments.

We also prioritize on-going education and training for all employees across our organization as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ◦ *Engineering Apprenticeship Program:* Given the increasing challenges within the real estate industry of attracting qualified engineers throughout the country, we made it a strategic priority to develop the next generation of qualified building engineers. Our Engineering Apprenticeship Program standardizes the recruitment and development of engineering candidates to prepare them for open positions and to plan for future engineering needs. We recruit from various trade schools and job fairs to identify candidates for the two-year program with a curriculum that includes specific onboarding plans for training in electrical, HVAC, or plumbing trades and covers a range of essential engineering staff development topics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ◦ *Industry Associations & Credentials:* In order to further their professional development, many of our employees seek out credentials and association memberships, with any membership costs reimbursed by us. Examples of credentials and association memberships include: BOMA membership, Certified Property Manager, Certified Public Accountant, National Association of Industrial and Office Properties, LEED Accredited Professional, Certified Energy Manager and Fitwel Ambassador.

In 2025, we were recognized by GlobeSt. as one of commercial real estate's Best Places to Work for the second consecutive year and in 2024 by Commercial Property Executive as 11th on its list of Top Commercial Property Management Companies. In 2023, we were recognized by The Boston Globe for the fourth consecutive year as one of The Top Places to Work in Massachusetts in the Large Employers category.

### Our Board's Role in Oversight of Risk Management
Our Board is elected by our shareholders to oversee our business and long term strategy. As part of fulfilling its responsibilities, our Board oversees the maintenance of appropriate financial and other internal controls and our compliance with applicable laws and regulations. Inherent in these responsibilities is our Board's understanding and oversight of the various risks we face. Our Board considers that risks should not be viewed in isolation and should be considered in virtually every business decision and as part of our business strategy.

Our Board oversees risk as part of its general oversight of our Company. Oversight of risk is addressed as part of various Board and Board committee activities and through regular and special Board and Board committee meetings. Our day to day business is conducted by our management, which is responsible for incorporating risk management in its activities. Our management and our internal audit provider regularly meet with our Audit Committee and provide us with advice and assistance with our risk management function.

In discharging their oversight responsibilities, our Board and Board committees review regularly a wide range of reports management, internal audit and service providers provide, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reports on market and industry conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • operating and regulatory compliance reports;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • financial reports;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reports on risk management and sustainability activities and initiatives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • regulatory and legislative updates that may impact us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reports on artificial intelligence and the security of our information technology processes and our data; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • legal proceeding updates and reports on other business related matters.

Our Board and Board committees discuss these matters among themselves and with our management, legal counsel, our independent auditors and other professionals, as appropriate.

Our Audit Committee takes a leading role in helping our Board fulfill its responsibilities for oversight of our financial reporting, internal audit function, risk management, including cybersecurity and the use of artificial intelligence, and our compliance with legal and regulatory requirements. Our Board and Audit Committee review periodic reports from our independent auditors regarding potential risks, including risks related to our internal control over financial reporting. In 2025, following an analysis of our internal audit function, our Audit Committee engaged PricewaterhouseCoopers LLP to serve as our internal audit provider. Our Audit Committee reviews an internal audit plan developed by our internal audit provider with the goal of helping us systematically evaluate the effectiveness of our risk management, control and governance processes on an annual basis. Our Audit Committee meets at least quarterly and reports its findings to our Board. Our Audit Committee also meets periodically with our internal audit provider to review the results of our internal audits, and directs or recommends to our Board actions or changes it determines appropriate to enhance or improve the effectiveness of our risk management.

Our Audit Committee considers risks related to cybersecurity and receives regular reports from our management regarding cybersecurity risks and countermeasures being undertaken or considered by us, including updates on the internal and external cybersecurity landscape and relevant technical developments, such as advances in the use of artificial intelligence.

Our Compensation Committee whose responsibilities are detailed in its charter, among other responsibilities, reviews the goals and objectives of our executive compensation program; reviews and approves annually the compensation paid by us to each of our executive officers; and reviews and considers the incentives and risks associated with our compensation policies and practices. Also, our Compensation Committee and our Board consider that we have a share award program that requires share awards to executive officers to vest over a period of years. We believe that the use of share awards vesting over time rather than stock options mitigates the incentives for our management to undertake undue risks and encourages our management to make longer term and appropriately risk balanced decisions. In addition, beginning in May 2025, our Compensation Committee and our Board also consider that the RMR Residential Promote Program allows our senior level employees, who provide services to the RMR Residential business, to acquire an interest in certain investments of the RMR Residential business and participate in the long-term growth and financial success of the RMR Residential business, conditioned upon such participants making a capital contribution with respect to such investments. We believe that allowing these individuals to directly participate in the success of specific investments and conditioning such interests on a capital contribution and a four year vesting schedule aligns the interests of the RMR Residential business and the participants.

It is not possible to identify all of the risks that may affect us or to develop processes and controls to eliminate all risks and their possible effects, and processes and controls employed to address risks may be limited in their effectiveness. Moreover, it is necessary for us to bear certain risks to achieve our objectives. As a result of the foregoing and other factors, our ability to manage risk is subject to substantial limitations.

To learn more about the risks we face, you can review the matters discussed in Part I, Item 1A. "Risk Factors" and "Warning Concerning Forward Looking Statements" in our Annual Report to Shareholders for the fiscal year ended September 30, 2025 (the "Annual Report"). The risks described in the Annual Report are not the only risks we face. Additional risks and uncertainties not currently known or that may currently be deemed to be immaterial also may materially adversely affect our business, financial condition or results of operations in future periods.

### Director Independence
Under the corporate governance listing standards of the Nasdaq, to be considered independent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a director must not have a disqualifying relationship, as defined in the corporate governance section of the Nasdaq rules; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our Board must affirmatively determine that the director otherwise has no relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. To facilitate the director independence assessment process, our Board has adopted written Governance Guidelines as described below.

Our Board is comprised of six Directors, including four Independent Directors and two Managing Directors. Under our bylaws (our "Bylaws"), so long as the number of directors is less than five, at least one director must meet the qualifications of a Managing Director and, so long as the number of directors is five or greater, at least two directors must meet the qualifications of a Managing Director. As set forth in our Bylaws, Independent Directors are Directors who are not employees of our Company or any of our subsidiaries, are not involved in our or our subsidiaries' day to day activities and are persons who qualify as independent under the applicable rules of the Nasdaq and the Securities and Exchange Commission (the "SEC"). As set forth in our Bylaws, Managing Directors are Directors who are not Independent Directors and who have been employees of our Company or any of our subsidiaries or involved in our day to day activities, or the activities of any of our subsidiaries or any of their predecessors for at least one year prior to such Director's election.

Our Board affirmatively determines whether Directors have a direct or indirect material relationship with us, including our subsidiaries, other than serving as our Directors or directors of our subsidiaries. In making independence determinations, our Board observes the Nasdaq and SEC criteria, as well as the criteria set forth in our governing documents. When assessing a Director's relationship with us, our Board considers all relevant facts and circumstances, not merely from the Director's standpoint, but also from that of the persons or organizations with which the Director has an affiliation. Based on this review, our Board has determined that Ann Logan, Rosen Plevneliev, Jonathan Veitch and Walter C. Watkins, Jr. currently qualify as independent directors under applicable Nasdaq and SEC criteria and as Independent Directors under our Bylaws. In making these independence determinations, our Board reviewed and discussed additional information provided by us and the Directors with regard to each of the Directors' relationships with us and our affiliates and those companies to which we or our affiliates provide management or advisory services, as applicable. Our Board has concluded that none of these four Directors possessed or currently possesses any relationship that could impair her or his judgment in connection with her or his duties and responsibilities as a Director of our Company or that could otherwise be a direct or indirect material relationship under applicable Nasdaq and SEC standards.

### Executive Sessions of Independent Directors
Pursuant to our Governance Guidelines, our Independent Directors meet in regularly scheduled meetings at which only Independent Directors are present. Our Independent Directors also meet with our officers, other representatives of our management, as appropriate, and with our independent auditors. The presiding Director for purposes of leading Independent Director sessions is the Lead Independent Director, unless the Independent Directors determine otherwise.

### Board Leadership Structure
All Directors play an active role in overseeing our business both at our Board and committee levels. As set forth in our Governance Guidelines, the core responsibility of our Directors is to exercise sound, informed and independent business judgment in overseeing our Company and our strategic direction. Our Directors are skilled and experienced leaders and currently serve or have served as members of senior management in public and private for profit and nonprofit organizations, and also have served as government officials and in academia. Our Directors may be called upon to provide solutions to various complex issues and are expected to, and do, ask hard questions of our officers and advisers. Our Board is small, which facilitates informal discussions and communication from our management to our Board and among Directors.

Adam Portnoy has served as Chair of our Board since 2022. Our Board believes that Mr. Portnoy's leadership and extensive familiarity with our day to day business provide valuable insight for our Board. Our Chief Financial Officer and Treasurer regularly attends Board and Board committee meetings. Special meetings of our Board may be called at any time by our President or by a majority of the Directors then in office. Our Managing Directors, in consultation with our management, set the agenda for Board meetings. Other Directors may suggest agenda items as well. Discussions at Board meetings are led by the Chair of the Board, the Managing Director, the Independent Director or a member of management who is most knowledgeable on a subject.

Four of our Directors are independent under the applicable Nasdaq and SEC criteria and our governing documents. All of the members of our Audit Committee, Nominating and Governance Committee and Compensation Committee are independent under the applicable listing requirements and rules of the Nasdaq and other applicable laws, rules and regulations, including those of the SEC. As set forth in our Bylaws, two of our Directors are Managing Directors, persons who have been employees of our Company or our subsidiaries or involved in our day to day activities or in the day to day activities of any of our subsidiaries or any of their predecessors for at least one year prior to such Director's election.

### Lead Independent Director
We have a Lead Independent Director who is selected annually by the vote of a majority of our Independent Directors. Currently, Mr. Plevneliev serves as our Lead Independent Director. Our Lead Independent Director has well-defined, robust responsibilities that include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • assisting the board in evaluating its effectiveness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • presiding at all meetings of our Board at which the Chair or a Managing Director is not present;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • presiding at all meetings and executive sessions of the Independent Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • having the authority to call meetings of the Independent Directors or executive sessions of the Independent Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • serving as the principal liaison between the Independent Directors and our management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • assisting our Compensation Committee in its annual evaluation of the performance of our executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • setting agendas for meetings of the Independent Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • authorizing the retention of advisors and consultants who report directly to the Independent Directors when appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if requested, and in coordination with the Chair of our Board and our management, being reasonably available for consultation and direct communication with shareholders.

### Code of Business Conduct and Ethics and Committee Governance
Our Board is committed to corporate governance that promotes the long term interests of our shareholders. Our Board has established Governance Guidelines that provide a framework for effective governance. Our Board regularly reviews developments in corporate governance and updates our Governance Guidelines and other governance materials as it deems necessary and appropriate.

We have also adopted a Code of Business Conduct and Ethics (the "Code") to, among other things, provide guidance to our Directors, officers and employees to ensure compliance with applicable laws and regulations.

Our Board has an Audit Committee, Compensation Committee and Nominating and Governance Committee. Our Audit Committee, Compensation Committee and Nominating and Governance Committee each have adopted a written charter, and each Board committee reviews its written charter on an annual basis to consider whether any changes are required.

[**TABLE OF CONTENTS**](#TOC)

Our Audit Committee, Compensation Committee and Nominating and Governance Committee are comprised entirely of Independent Directors under applicable Nasdaq rules who also meet the independence criteria applicable to audit committees and compensation committees under the Sarbanes-Oxley Act of 2002 and the SEC's implementing rules under that law.

We are a "controlled company" under the rules of the Nasdaq because Adam Portnoy holds more than 50% of our voting power. Although that would allow our Compensation Committee and Nominating and Governance Committee to include Independent Directors and Managing Directors, both committees are comprised solely of Independent Directors.

Our corporate governance materials are available for review in the governance section of our website, including our Governance Guidelines, the charter for each Board committee, the Code and information about how to report concerns or complaints about accounting, internal accounting controls or auditing matters and any violations or possible violations of the Code and how to communicate with our Directors, individually or as a group. To access these documents on our website visit *www.rmrgroup.com*. We intend to satisfy the requirements under Item 5.05 of Form 8-K regarding disclosure of amendments to, or waivers from, provisions of our Code that apply to the principal executive officer, principal financial officer or controller, or persons performing similar functions, by posting such information on our website.

### Insider Trading Policies and Procedures
We have adopted Insider Trading Policies and Procedures (our "Insider Trading Policy") governing the purchase, sale, and other dispositions of our securities by our Directors, officers and employees, and the Company itself, that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable Nasdaq listing standards. In general, our Insider Trading Policy prohibits us and our Directors, officers and employees and related persons and entities from trading in our securities and securities of any public company to which RMR LLC or its affiliates provide management services (our "Public Clients") while aware of material, nonpublic information about us or such company. Our Insider Trading Policy also prohibits our Directors and Executive Officers and other designated employees from transacting in our securities and securities of our Public Clients during certain designated blackout periods. In addition, our Directors and certain senior officers are required to obtain approval in advance of transactions in our securities. The foregoing summary of our Insider Trading Policy does not purport to be complete and is qualified by reference to our Insider Trading Policy, a copy of which can be found as an exhibit to our Annual Report on Form 10-K for the fiscal year ended September 30, 2025.

### Prohibition on Hedging
Our Insider Trading Policy expressly prohibits members of our Board and our officers from engaging in hedging transactions involving our securities and those of any public company to which RMR LLC or its affiliates provide management services.

### Nominations for Directors
Our Nominating and Governance Committee is responsible for identifying and evaluating nominees for Director and for recommending to our Board nominees for election at each annual meeting of shareholders. Our Nominating and Governance Committee may consider candidates suggested by our Directors, officers or shareholders or by others. Shareholders who would like to recommend a nominee for the position of Director should submit their recommendations in writing by mail to the Chair of our Nominating and Governance Committee, c/o Secretary, The RMR Group Inc., at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458 or by email to secretary@rmrgroup.com.

Our Nominating and Governance Committee may request additional information about the shareholder recommended nominee or about the shareholder recommending the nominee. Recommendations by shareholders will be considered by our Nominating and Governance Committee in its discretion using the same criteria as other candidates it considers.

PROPOSAL 1: ELECTION OF DIRECTORS

Upon the recommendation of our Nominating and Governance Committee, our Board has nominated Matthew P. Jordan and Adam Portnoy for election as Managing Directors and Ann Logan, Rosen Plevneliev, Jonathan Veitch and Walter C. Watkins, Jr. for election as Independent Directors. Each Director nominee currently serves on our Board. If elected, each nominee would serve until our 2027 annual meeting of shareholders and until her or his successor is duly elected and qualifies, subject to the individual's earlier death, resignation, retirement, disqualification or removal.

We expect that each nominee for election as a Director will be able to serve if elected. However, if a nominee should become unable or unwilling to serve, proxies may be voted for the election of a substitute nominee designated by our Board.

#### Director Criteria, Qualifications, Experience and Tenure
Our Board performs an assessment of the skills and the experience needed to properly oversee the interests of our Company. Generally, our Board reviews both the short- and long-term strategies of our Company to determine what current and future skills and experience are required of our Board in exercising its oversight function and in the context of our strategic priorities. Our Nominating and Governance Committee and our Board consider the qualifications, characteristics and skills of Directors and Director candidates individually and in the broader context of our Board's overall composition when evaluating potential nominees for election as Director.

Our Board believes that its members should:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • exhibit high standards of integrity and ethics; <br>&nbsp;&nbsp;&nbsp;&nbsp; • have business acumen, practical wisdom, ability to exercise sound judgment in a congenial manner and be able to make independent analytical inquiries; <br>&nbsp;&nbsp;&nbsp;&nbsp; • have a strong record of achievements; <br>&nbsp;&nbsp;&nbsp;&nbsp; • have knowledge of the asset management industry, commercial real estate ("CRE") and residential real estate industries and real estate investment trusts ("REITs"); <br>| &nbsp;&nbsp;&nbsp; • have diverse perspectives, backgrounds and experiences, including professional background, skills and community membership; and <br>• be committed to serve on our Board over a period of years in order to develop knowledge about our operations and have sufficient time and availability to devote to Board and committee matters. <br>|

---

In addition, our Board has determined that our Board, as a whole, should strive to have the right mix of characteristics and skills necessary to effectively perform its oversight responsibilities. Our Board believes that Directors with one or more of the following professional skills or experiences can assist in meeting this goal:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • work experience with a proven record of success in his, her or their field; <br>&nbsp;&nbsp;&nbsp;&nbsp; • risk oversight/management expertise; <br>&nbsp;&nbsp;&nbsp;&nbsp; • accounting and finance, including a high level of financial literacy and understanding of the impact of financial market trends on the real estate industry; <br>&nbsp;&nbsp;&nbsp;&nbsp; • operating business and/or transactional experience; <br>&nbsp;&nbsp;&nbsp;&nbsp; • management/leadership experience; <br>&nbsp;&nbsp;&nbsp;&nbsp; • knowledge of our historical business activities; <br>&nbsp;&nbsp;&nbsp;&nbsp; • familiarity with client sectors; <br>| &nbsp;&nbsp;&nbsp; • familiarity with the public capital markets; <br>• experience at a strategic or policymaking level in a business, government, non-profit or academic organization of high standing; <br>• service on other public company boards and committees; <br>• qualifying as a Managing Director in accordance with the requirements of our governing documents; and <br>• qualifying as an Independent Director in accordance with the requirements of the Nasdaq, the SEC and our governing documents. <br>|

BOARD MEETINGS

In the fiscal year 2025, our Board held five meetings. In the fiscal year 2025, each Director then in office attended 75% or more of the aggregate of all meetings of our Board and the committees on which he or she served or that were held during the period in which the Director served as a Director or committee member. All of our Directors then in office attended last year's annual meeting of shareholders. Our policy with respect to Board members' attendance at meetings of our Board and annual meetings of shareholders can be found in our Governance Guidelines, the full text of which appears at our website, *www.rmrgroup.com*.

DIRECTOR COMPENSATION

### Compensation of Directors
Our Board believes that competitive compensation arrangements are necessary to attract and retain qualified Independent Directors. Under the currently effective Director compensation arrangements, each Independent Director received an annual fee of $97,500 for services as a Director. The annual fee for any new Independent Director is prorated for the initial year of service. Each Independent Director and Managing Director also received an award of Class A Common Shares for serving as a Director with a value equal to $100,000 based on the closing price of our Class A Common Shares on the date of the grant, rounded down to the nearest whole share, which resulted in an award of 5,988 Class A Common Shares to each Director in fiscal year 2025.

Each Independent Director who served as a committee chair of our Audit, Compensation or Nominating and Governance Committees received an additional annual fee for such service of $20,000, $15,000 and $15,000, respectively, and our Lead Independent Director also received an additional annual fee of $17,500 for serving in this role. Directors were reimbursed for travel expenses they incurred in connection with their responsibilities as Directors and for out of pocket costs they incurred in connection with their attending certain continuing education programs, if any.

### Fiscal Year 2025 Director Compensation
The following table details the total compensation of our Directors for the fiscal year ended September 30, 2025 for services as a Director.

PROPOSAL 2: ADVISORY VOTE TO APPROVE

EXECUTIVE COMPENSATION

As required by Section 14A of the Exchange Act, we are seeking a nonbinding advisory vote from our shareholders to approve the compensation of our named executive officers as described in the "Compensation Discussion and Analysis" section beginning on page [27](#tCDAA) and the "Executive Compensation" section beginning on page [37](#tEXCO).

Our Board recommends that shareholders vote "FOR" the following resolution:

Approval of the advisory vote to approve executive compensation requires the affirmative vote of a majority of all the votes cast, in person or by proxy, at our 2026 Annual Meeting.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis describes the fiscal year 2025 compensation of our named executive officers. For fiscal 2025, our named executive officers were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Adam Portnoy, Chair of our Board, Managing Director, President and Chief Executive Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Jennifer B. Clark, former Managing Director, Executive Vice President, General Counsel and Secretary

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Matthew P. Jordan, Managing Director, Executive Vice President, Chief Operating Officer and former Chief Financial Officer and Treasurer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • John G. Murray, Executive Vice President\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Christopher J. Bilotto, Executive Vice President

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Jeffrey Leer, Executive Vice President

### Compensation Overview
We strive to maintain an executive compensation program which reflects best practices. We compensate our executive officers with a combination of base salary, cash bonus and equity compensation awards, and we also recommend to certain of our clients that they award equity to our executive officers as well. Our executive compensation program is intended to recognize each executive officer's scope of responsibilities, reward demonstrated performance and leadership and motivate continued employment and high levels of service. Two of our executive officers are also chief executive officers of, and dedicate most of their time to, two of our clients that pay cash compensation to their officers: John G. Murray, is the chief executive officer of Sonesta International Hotels Corporation ("Sonesta") and Jeffrey Leer is the chief executive officer of AlerisLife, Inc. ("AlerisLife"). Each of Mr. Murray and Mr. Leer dedicated most of his time to Sonesta and AlerisLife, respectively, during fiscal 2025. Accordingly, each of the Sonesta board of directors and the AlerisLife board of directors determined Mr. Murray's and Mr. Leer's cash compensation, respectively, during 2025, and the cash compensation we paid to Messrs. Murray and Leer is based on a percentage allocation of their business time and efforts to Sonesta and AlerisLife, as applicable, and to us. Because we determined that at least 90% of Messrs. Murray's and Leer's business time during fiscal 2025 was devoted to services to Sonesta and AlerisLife, respectively, 90% of each of their total cash compensation (that is, the combined base salary and cash bonus paid by us and Sonesta or AlerisLife, as applicable) was paid by Sonesta or AlerisLife, as applicable, and the remainder was paid by us. We believe the compensation we paid to Messrs. Murray and Leer in fiscal year 2025 reasonably reflected their division of business time and efforts. Periodically Messrs. Murray and Leer may divide their business time and efforts differently than they do currently and their compensation from us may not immediately reflect this division. Our Compensation Committee considers the percentage allocation of Messrs. Murray's and Leer's business time and efforts at least annually.

The competition for executive talent is strong both nationally and in the areas where we and our clients are headquartered. Our ability to attract, retain and appropriately reward our executive officers is essential to maintaining our business results. Our Compensation Committee's goals are to have comprehensive compensation programs that incentivize and reward executives toward achievement of our operational, financial and strategic goals. This includes maintaining a "pay-for-performance" culture, in which substantial portions of total compensation are "at risk" and based upon attainment of our business objectives and our executives' performance and skills. Our compensation program is also designed to align executives' interests with those of our shareholders, our clients and their shareholders and to incentivize our executives based upon our performance and the performance of our clients. Awards of equity-based compensation encourage executives to focus on long-term growth and are tied to the interests of our shareholders.

\*

Pursuant to the letter agreement among RMR LLC, Sonesta and John G. Murray, dated as of January 12, 2026, (the "Murray Retirement Agreement"), Mr. Murray will resign from his roles as an officer of RMR LLC and as an officer and director of Sonesta, effective March 31, 2026, and will continue as a non-executive employee of Sonesta until his retirement, effective September 30, 2026.

[**TABLE OF CONTENTS**](#TOC)

As part of our efforts to attract, retain and appropriately reward our executive officers, in May 2025 we adopted The RMR Group Inc. Residential Promote Program (the "RMR Residential Promote Program") to enable our senior level employees, who provide services to the RMR Residential business, to acquire an interest in a share of the income and distributions related to certain investments by the RMR Residential business and to participate in the long-term growth and financial success of the RMR Residential business. Participants in the RMR Residential Promote Program are obligated to make a capital contribution with respect to the applicable RMR Residential investment in which they receive promote interests and such interests are subject to a four year, time-based vesting schedule. The allocation of interests pursuant to the RMR Residential Promote Program is a small component of our overall compensation program and is intended to create direct alignment of interests among the RMR Residential business and our executives involved in this business.

#### Summary of Fiscal 2025 Named Executive Officer Compensation
In fiscal 2025, we paid each of our named executive officers cash compensation for services provided by the officers to us and our clients. The cash compensation consisted of base salary and discretionary cash bonus.

We did not provide guaranteed cash bonuses to our named executive officers during fiscal 2025 and did not set specific performance targets on which bonuses would be payable to them. Instead, the annual cash bonuses we paid to our named executive officers (other than our Managing Director, President and Chief Executive Officer) in fiscal 2025 were based on a performance evaluation conducted by our Managing Director, President and Chief Executive Officer regarding each other executive officer's performance, other than Ms. Clark whose cash bonus compensation was agreed upon in her retirement agreement with RMR LLC, dated as of February 5, 2025 (the "Clark Retirement Agreement"). These evaluations were presented to our Compensation Committee, and our Compensation Committee also evaluated our Managing Director, President and Chief Executive Officer's performance. The impact of market and industry conditions, including uncertainty regarding inflation and interest rates and the challenging environment for commercial and residential real estate, on our and our clients' businesses and the ratio of cash and equity compensation were considered (among other things) in determining our executives' base salary and cash bonuses.

Consistent with our approach in fiscal 2024, the Compensation Committee determined a set dollar value for each share award rather than setting the number of shares. As part of the considerations described above, we awarded in fiscal 2025 a number of Class A Common Shares equal to $600,000 based on the closing share price on the grant date, rounded down to the nearest whole number to Mr. Portnoy, a number of Class A Common Shares equal to $300,000 (also rounded down to the nearest whole number) to each of Mr. Jordan and Ms. Clark and a number of Class A Common Shares equal to $150,000 (also rounded down to the nearest whole number) to each of Messrs. Murray, Bilotto and Leer. Accordingly, Mr. Portnoy received 35,587 shares with a grant date fair value of $599,997, Mr. Jordan and Ms. Clark each received 17,793 shares with a grant date fair value of $299,990, and Messrs. Murray, Bilotto and Leer each received 8,896 shares with a grant date fair value of $149,987. One fifth of the shares awarded vest on the award date and an additional one fifth vest on each of the next four anniversaries of the award date, subject to the named executive officer continuing to render significant services to us or to one of our clients and to accelerated vesting under certain circumstances.

Our named executive officers, also received equity awards from our public clients, other than OPI, and Mr. Murray, Sonesta's director, president and chief executive officer, and Mr. Leer, AlerisLife's president and chief executive officer, also received cash compensation from Sonesta and AlerisLife, respectively. These equity awards and cash compensation are determined by the compensation committees of the applicable client other than Sonesta and AlerisLife, which are comprised solely of independent board members. Mr. Murray's and Mr. Leer's cash compensation from Sonesta and AlerisLife, respectively, is determined by the Sonesta board of directors and the AlerisLife board of directors, as applicable.

As described more fully under "Overview of Fiscal 2025 Compensation Actions," during fiscal 2025, pursuant to the RMR Residential Promote Program, Messrs. Portnoy and Jordan received an allocation of up to 6.5% of the aggregate interests available to participants in the RMR Residential Promote Program for the applicable RMR Residential investment, and Mr. Bilotto received an allocation of up to 2% of the aggregate interests available to participants in the RMR Residential Promote Program for the applicable RMR Residential

investment. If a participant is no longer employed by or affiliated with RMR LLC or its subsidiaries or affiliates, then the non-vested portion of such participant's interests under the RMR Residential Promote Program will be forfeited and the vested portion will be converted to a non-voting economic interest under the RMR Residential Promote Program. During fiscal 2025, no distributions were made to our executive officers under the RMR Residential Promote Program.

#### Named Executive Officer Compensation Philosophy and Process
The key principle of our compensation philosophy for our named executive officers is to pay for performance.

Our named executive officer compensation planning process incorporates key areas of evaluation, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • external market data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • internal benchmarking; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • quantitative and qualitative assessments of our company, group and individual performance.

**Named Executive Officer Compensation Practices.** Our pay for performance compensation philosophy is reflected in our compensation practices, which for our fiscal 2025 included the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no guaranteed salary increases or guaranteed cash bonuses other than retirement bonuses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no specific performance targets on which bonuses would be paid;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no additional performance awards for growing assets under management or for exceeding return benchmarks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no distributions paid on Promote Interests until corresponding investments are cash flow positive;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no excessive perquisites;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no tax gross-ups;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • annual assessment of named executive officer compensation against peer companies and best practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • holistic performance evaluations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • annual salary cap.

**Components of the Named Executive Officers' Compensation.** Our executive compensation program includes an annual base salary, a cash bonus, an equity award and, in some cases, allocation of interests in the RMR Residential Promote Program. In addition to the Class A Common Shares we award to our named executive officers, our named executive officers also receive equity awards from our clients, and Mr. Murray and Mr. Leer received cash compensation from Sonesta and AlerisLife, respectively. The cash bonuses paid to our named executive officers are discretionary in amount, are based on a performance evaluation and are determined by our Compensation Committee, other than with respect to Mr. Murray and Mr. Leer whose bonus amounts are determined by Sonesta's and AlerisLife's boards of directors, as applicable. We also paid Ms. Clark a bonus in accordance with the Clark Retirement Agreement. The evaluation involves an analysis of both (i) our overall performance and the overall performance of our clients, and (ii) the performance of the individual officer and his, her or their contributions, and services provided, to us and our clients. We believe this evaluation process allows us to link pay with performance in the closest way possible and provides us with the flexibility necessary to take all relevant factors into account in determining the bonus amounts, including the named executive officer's ability to react to changing circumstances that impact our business and the businesses of our clients, including this year, the impact of market and industry conditions, including uncertainty regarding inflation and interest rates and the challenging environment for commercial and residential real estate, on our and our clients' businesses.

We also annually award Class A Common Shares to our named executive officers. One fifth of the shares awarded vest on the award date and an additional one fifth vest on each of the next four anniversaries of the award date, subject to the named executive officer continuing to render significant services to us or to one of our clients and to accelerated vesting under certain circumstances.

In addition, certain named executive officers were allocated Promote Interests in certain investments through the RMR Residential Promote Program, which vest upon a termination of employment other than for cause or resignation based on length of service following the grant date.

The table below describes the objectives supported by each of our compensation elements, along with an overview of the key design features of each element.

**Named Executive Officer Pay Mix.** Our compensation program is designed so that the majority of compensation is performance based to promote alignment of our named executive officers' interests with those of our shareholders, our clients and their shareholders.

The base salary payments of our named executive officers (which represent the fixed portion of their compensation packages) are reviewed annually and may be adjusted as we deem appropriate. We historically adjust salary payments on October 1, the first day of our fiscal year. During fiscal 2025, each of our named executive officers received a base salary of $375,000. We paid $37,500 of each of Messrs. Murray's and Leer's base salaries during our fiscal 2025, which represented 10% of each of their base salaries during fiscal 2025, and Sonesta and AlerisLife, as applicable, paid the remaining amount of each of their salaries for fiscal 2025.

Our Compensation Committee considers a number of factors in determining bonus compensation for our named executive officers (other than for Mr. Murray and Mr. Leer whose bonus amounts were determined by Sonesta's board of directors or AlerisLife's board of directors, as applicable, and for Ms. Clark whose bonus amount was paid in accordance with the Clark Retirement Agreement, which was approved by our Compensation Committee), including our and our clients' overall financial performance. For fiscal 2025, our Compensation Committee considered changes in our revenues and assets under management as well as certain significant transactions by us and our clients in which our named executive officers played a significant role. For example, our Compensation Committee considered among other things (i) the growth of the RMR Residential business and other private capital initiatives, (ii) our $100,000 senior secured revolving

credit facility, (iii) the restructuring of debt at DHC, ILPT and SVC, (iv) the sale of properties by several clients, (v) management of OPI's ongoing financial and performance challenges and its consideration of a restructuring process, (vi) the agreement to sell AlerisLife's properties and management agreements and (vii) other significant acquisitions, dispositions and refinancing activities by us and our clients (collectively, the "<u>2025 Transactions</u>").

In addition, our Compensation Committee considered our executive officers' success leading us and our clients through the ongoing market and industry conditions and other macroeconomic conditions, including the impact of uncertainty regarding inflation and interest rates, restructuring of the debt of certain of our public clients and the challenging environment for commercial and residential real estate, on our and our clients' businesses.

We also awarded Class A Common Shares to each of our named executive officers for fiscal 2025, and Messrs. Portnoy, Jordan and Bilotto each made a capital contribution to and received an allocation of Promote Interests in certain RMR Residential investments pursuant to the RMR Residential Promote Program, each as described above.

Because the year-end bonus is discretionary and based on a number of factors, there is no pre-set pay mix that applies to the compensation of our named executive officers generally.

**Say-on-Pay Vote.** At our 2025 annual meeting of shareholders, the percentage of shares voting that approved our advisory "Say-on-Pay" vote was approximately 99%. Our Compensation Committee believes that this support level demonstrates a strong alignment among our shareholders, our performance, and our executive compensation program. Accordingly, our Compensation Committee did not make any changes to the Company's executive compensation program in response to the 2025 "Say-on-Pay" vote.

### Overview of Fiscal 2025 Compensation Actions
Our Compensation Committee evaluated and administered our executive compensation program. This evaluation typically includes an assessment of our and our clients' performance, the effectiveness of existing programs in achieving the goals of the program, developments in our business situation and goals, executive compensation best practices, tax and accounting considerations, investor feedback and such other factors as our Compensation Committee determines appropriate to consider from time to time. As part of this evaluation, our Compensation Committee received input from our President and Chief Executive Officer (with respect to executives other than himself).

These evaluations also typically include an assessment of the risk associated with the program and each element thereof and also take into account developments in the overall market for executive talent. Our Compensation Committee does not engage in any formal compensation benchmarking, but does take note of compensation practices and trends from an identified peer group of companies in making its decisions. For fiscal 2025, the peer group of companies which informed Compensation Committee decisions consisted of the following companies: Brookfield Corporation, Bridge Investment Group Holdings Inc., Cohen & Steers Inc., Kennedy-Wilson Holdings Inc. and RITHM Capital Corp. This group of peer companies includes alternative asset managers and investment managers specializing in real estate, and we believe that these peer companies are comparable to us based on such companies' business activity, market capitalization, funds from operations, total assets and alignment with peer groups selected by proxy advisory firms.

Our Compensation Committee also does not have rules or policies with respect to allocation of compensation to short or long term vehicles or as between cash or non-cash elements of compensation; such determinations are made by our Compensation Committee on a discretionary basis under the facts and circumstances applicable from time to time.

On May 2, 2025, the Board, accepting the recommendation of the Compensation Committee, adopted the RMR Residential Promote Program. The purpose of the RMR Residential Promote Program is to enable RMR LLC and its subsidiaries to attract, retain and incentivize senior level employees of RMR LLC and its subsidiaries and to enable such individuals to acquire an interest in a share of the income and distributions related to certain investments by RMR Residential and to otherwise participate in the long-term growth and financial success of RMR Residential. Fifty percent of the pool of distributions from each selected

[**TABLE OF CONTENTS**](#TOC)

investment are allocated to a subsidiary of RMR LLC, and fifty percent of the pool is available for participants in the RMR Residential Promote Program. Each participant in the RMR Residential Promote Program is allocated Promote Interests expressed as a percentage of the aggregate interests available to participants for the applicable RMR Residential investment and becomes a member of RMR Employee Carry Holdco LLC, a limited liability company managed by RMR LLC ("RMR Employee Carry"), which will hold indirect interests in certain investments made by RMR Residential.

Each participant in the RMR Residential Promote Program executes an individual participation agreement that sets forth the terms and conditions of their participation in the RMR Residential Promote Program, including such participant's obligation to make a capital contribution to RMR Employee Carry in respect of the applicable RMR Residential investment, the percentage of the distributions from RMR Employee Carry that a participant will be entitled to receive and the vesting schedule applicable to the Promote Interests.

The RMR Residential Promote Program is administered by RMR LLC which will have authority to determine the participants and the respective amounts of such participants' interests under the RMR Residential Promote Program, other than with respect to any of our named executive officers whose respective allocations under the RMR Residential Promote Program are determined by the Compensation Committee.

In September 2025, our Compensation Committee Chair met with Adam Portnoy and the compensation committee chairs of our public clients, which consisted of: Diversified Healthcare Trust ("DHC"), Industrial Logistics Properties Trust ("ILPT"), Office Properties Income Trust ("OPI"), Service Properties Trust ("SVC") and Seven Hills Realty Trust ("SEVN"). The purposes of this meeting were, among other things, to discuss compensation philosophy and factors that may affect compensation decisions, to discuss the base salaries of our executive officers for fiscal 2026, to consider the allocation of internal audit and related services costs among us and our clients, to provide a comparative understanding of potential share awards by us and our clients and to hear and consider our recommendations and those from our clients concerning potential share awards and the vesting of those shares, which were in part based on the results of our review of current market practices with respect to executive compensation, and specifically of our and our clients' peer groups, and shareholder feedback received during shareholder outreach with respect to the percentage of executive officer compensation received in share awards. The share awards made by our clients are considered to be appropriate comparisons because of the similarities between certain services we require from our share awardees and the services provided by awardees providing similar services to our clients. Subsequent to this meeting, the members of our Compensation Committee held a meeting at which our Compensation Committee Chair provided a report of the information discussed with Mr. Portnoy and others, and made recommendations for share awards to our named executive officers. Our Compensation Committee then discussed these recommendations and other factors, including the following factors for the fiscal 2025 share awards: (i) the value of the proposed share awards; (ii) the historical awards previously awarded to these named executive officers and the corresponding values at the time of the awards; (iii) our management's recommendations as presented by Mr. Portnoy; (iv) the value of share awards to executive officers providing comparable services at our public clients; (v) the scope of, and any changes to, the responsibilities assigned to, or assumed by, these named executive officers during the past year and on a going forward basis; (vi) the length of historical services by these named executive officers; (vii) our Compensation Committee's assessment of the quality of the services provided by these named executive officers in carrying out those responsibilities; and (viii) our financial and operating performance in the past year and our perceived future prospects. Our Compensation Committee considered these multiple factors in determining whether to increase or decrease the amounts of the prior year's awards. There was no formulaic approach in the use of these various factors in determining the number of shares to award to each named executive officer. The share amounts we awarded were determined by our Compensation Committee on a discretionary basis, using the various factors. The named executive officers did not participate in these meetings and were not involved in determining or recommending the amount or form of compensation they received from us, other than Mr. Portnoy who participated in the meetings and made recommendations with respect to the other named executive officers. The share amounts awarded by our clients (other than OPI which did not make share awards during fiscal 2025 to our named executive officers other than to Mr. Portnoy and Ms. Clark in their capacity as trustees of OPI) were determined by their respective compensation committees.

shareholders. Our Compensation Committee determines the cash compensation of our executive officers who do not also receive cash compensation from our clients. Mr. Murray's and Mr. Leer's cash compensation is determined by the Sonesta board of directors and the AlerisLife board of directors, respectively, and we paid cash compensation to each of them based on a percentage of that amount. We also paid Ms. Clark cash compensation in accordance with the Clark Retirement Agreement which was approved by our Compensation Committee.

**Base Salary.** The base salary payments for our named executive officers (which represents the fixed portion of their compensation packages) are reviewed annually and may be adjusted as we deem appropriate. We have historically set annual caps on annual base salary for our executive officers who do not also receive cash compensation from our clients, with a cap for fiscal year 2025 of $375,000. We historically adjust salary levels on October 1, the first day of our fiscal year. The cap on annual base salary for fiscal year 2026 did not change and was set at $375,000. Each of our named executive officers received an annual base salary of $375,000 for fiscal 2025. As described above, each of Sonesta and AlerisLife paid 90% of Messrs. Murray's and Leer's base salaries, as applicable, and we paid 10% of each of Messrs. Murray's and Leer's base salaries during fiscal 2025. These annual base salary levels are consistent with our pay for performance philosophy, which emphasizes "at risk" compensation as a larger proportion of named executive officer compensation.

**Annual Cash Bonuses.** Annual cash bonuses are a key component of our named executive officer compensation and represented the majority of the cash compensation we paid to each of our named executive officers for our 2025 fiscal year. We did not provide guaranteed cash bonuses to any of our named executive officers for fiscal year 2025 (other than to Ms. Clark whose cash bonus for fiscal 2025 was agreed upon in the Clark Retirement Agreement) and did not set specific performance targets on which bonuses would be payable. Instead, the annual cash bonuses we paid to our named executive officers with respect to fiscal year 2025 were discretionary in amount and were based on a performance evaluation conducted by our Compensation Committee. The evaluation by our Compensation Committee (which is described in more detail above) included an analysis of both (i) our and our clients' overall performance and (ii) the performance of the individual officer and his, her or their contributions to us and our clients. We believe this evaluation process allowed us to link pay with performance in the closest way possible and provided us with the flexibility necessary to take all relevant factors into account in determining the bonus amounts, including our named executive officers' ability to react to changing circumstances that impact our businesses and that of our clients.

On an aggregated basis, in fiscal 2025, our named executive officers received 15.1% of their total cash compensation in the form of base salary payments and the remaining 84.9% in the form of performance based discretionary bonuses. The foregoing amounts include a cash bonus we paid to Ms. Clark in accordance with the Clark Retirement Agreement and exclude cash compensation Sonesta paid to Mr. Murray and AlerisLife paid to Mr. Leer. We paid 10% of each of Messrs. Murray's and Leer's cash compensation during fiscal 2025.

We believe our compensation process provided us with a better compensation structure than a formulaic bonus structure based solely on the achievement of specific pre-established performance targets which may not capture all appropriate factors that materially impacted our clients or the individual named executive officer's performance. In fiscal 2025, we decreased bonus compensation for Mr. Portnoy as compared to fiscal 2024 due, in part, to our and our clients' performance during fiscal 2025, and shifted a portion of Mr. Portnoy's bonus compensation to the equity component of his compensation to further incentivize our growth. Mr. Jordan's bonus compensation was substantially the same as his bonus compensation in fiscal 2024 and Mr. Bilotto's bonus compensation increased as compared to fiscal 2024. Ms. Clark's bonus cash compensation was determined by the Clark Retirement Agreement, and Messrs. Murray's and Leer's bonus compensation was determined by the boards of directors of Sonesta and AlerisLife, as applicable. With respect to fiscal 2025 and for the reasons outlined above under "Named Executive Officer Pay Mix," we paid aggregate performance based discretionary cash bonuses of $8,871,250 to Messrs. Portnoy, Jordan, Murray, Bilotto and Leer and Ms. Clark (the specific amounts of which are set forth in the Summary Compensation Table). This amount includes the bonus we paid to each of Messrs. Murray and Leer and excludes the bonus that Sonesta and AlerisLife, as applicable, paid to each of Mr. Murray and Mr. Leer.

### Analysis of Fiscal 2025 Equity Awards

#### Class A Common Shares
At our 2025 annual meeting of shareholders, our shareholders approved The RMR Group Inc.'s Second Amended and Restated 2016 Omnibus Equity Plan (the "Plan") which rewards our named executive officers and other employees and aligns their interests with those of our shareholders and the shareholders of our clients. We award shares under the Plan to recognize our named executive officers' scope of responsibilities, reward demonstrated performance and leadership, motivate future performance, align the interests of our executives with those of our other shareholders and motivate our executives to remain our employees and to continue to provide services to us through the term of the awards. Our Compensation Committee considered these multiple factors in determining the amounts of the awards for fiscal 2025.

Under its charter, our Compensation Committee evaluates, approves and administers our equity compensation plans, including the Plan. Our Compensation Committee has historically determined to use awards of Class A Common Shares under the Plan rather than seek to issue stock options as equity compensation. We believe that the use of share awards vesting over time rather than stock options mitigates the incentives for our management to undertake undue risks and encourages management to make long term and appropriately risk balanced decisions.

Our Compensation Committee also considers the equity awards granted to our named executive officers by our public clients in determining the appropriate award of Class A Common Shares to our named executive officers. In fiscal 2025, our Compensation Committee considered the foregoing factors and the factors set forth above in "Overview of Fiscal 2025 Compensation Actions" and decided to award an aggregate of 97,861 Class A Common Shares to our named executive officers which amount includes the Class A Common Shares awarded to Ms. Clark pursuant to the Clark Retirement Agreement, which is an increase in the number of Class A Common Shares awarded to each of our named executive officers in fiscal 2024.

Our Compensation Committee has imposed, and may impose, vesting and other conditions on the awarded Class A Common Shares because it believes that time based vesting encourages the recipients of the share awards to remain employed by us and to continue to provide services to us. Our Compensation Committee currently uses a vesting schedule under which one fifth of the shares vest immediately and the remaining shares vest in four equal, consecutive annual installments commencing on the first anniversary of the date of the award. Our Compensation Committee utilizes a four year, time-based vesting schedule as an incentive to provide services for a long term and in consideration of the tax treatment of the share awards to us and to the recipients. In the event a recipient who received a share award ceases to render significant services, whether as an employee or otherwise, to us or to one of our clients during the vesting period, we may cause the forfeiture of the Class A Common Shares that have not yet vested. As with other issued Common Shares, vested and unvested shares awarded under the Plan are entitled to receive distributions that we make, if any, on the Common Shares.

Because the consideration of share awards by our Compensation Committee is determined on a regular schedule (i.e., in September for our officers and employees and at the first meeting of our Board after the annual meeting of shareholders for the Directors), any proximity of any awards to Plan earnings announcements or other market events is coincidental.

Our Compensation Committee believes that its compensation philosophy and programs are designed to foster a business culture that aligns the interests of our named executive officers with those of our shareholders. Our Compensation Committee believes that the equity compensation of our named executive officers is appropriate to the goal of providing shareholders dependable, long term returns.

#### Promote Interests
Our Board adopted the RMR Residential Promote Program to enable RMR LLC and its subsidiaries to attract, retain and incentivize senior level employees of RMR LLC and its subsidiaries and to enable such individuals to acquire an interest in a share of the income and distributions related to certain investments by RMR Residential and to otherwise participate in the long-term growth and financial success of RMR

Residential. Our Compensation Committee selects participants for the RMR Residential Promote Program, including our named executive officers, based on the participant's ability to directly impact the performance of our residential business.

#### Timing and Procedures for Fiscal 2025 Grants
Because the consideration of share awards by our Compensation Committee is determined on a regular schedule (i.e., in September for our officers and employees and at the first meeting of our Board after the annual meeting of shareholders for the Directors), any proximity of any awards to earnings announcements or other market events is coincidental.

#### Employment Agreements; Severance Arrangements
We have no employment agreements with our named executive officers or any of our other employees. Pursuant to the Plan, awards of restricted shares of our Class A Common Shares to our named executive officers provide for accelerated vesting in the event of certain termination and change in control events (as defined in the Plan). Our Compensation Committee has determined that such provisions are consistent with market practice and appropriate to further its goals of recruitment and retention.

Unless accelerated in the discretion of the Compensation Committee, each Promote Interest granted under the RMR Residential Promote Program vests upon the participant's termination of employment with the Company or its affiliates other than for cause based on length of service during the four-year period following the grant date—0% prior to the first anniversary of the grant date, 25% on or after the first but before the second anniversary of the grant date, 50% on or after the second but before the third anniversary of the grant date, 75% on or after the third but before the fourth anniversary of the grant date and 100% on or after the fourth anniversary of the grant date. All Promote Interests will be forfeited in full upon a participant's termination of employment for cause or breach of restrictive covenants.

Pursuant to the Clark Retirement Agreement, Ms. Clark continued to serve in her role as the Executive Vice President, General Counsel and Secretary until December 31, 2025 at which time she resigned from such offices and from any other officer or related positions within the Company, any of our managed companies or any of their affiliates. She will continue to serve as an employee of the Company until July 1, 2026. In connection with her retirement, Ms. Clark also resigned as a Managing Director, effective December 31, 2025. Under the Clark Retirement Agreement, Ms. Clark continued to receive her base salary until December 31, 2025. Ms. Clark was eligible to receive and received annual cash bonus for fiscal 2025 that was equal to the greater of the cash bonus paid to Mr. Portnoy for fiscal year 2025 and $2,880,000, and Ms. Clark was eligible to receive and received a grant of Class A Common Shares equal in value to the share grant she received in September 2024. Ms. Clark is also eligible to receive certain payments and benefits in 2026 pursuant to the Clark Retirement Agreement.

Pursuant to the Murray Retirement Agreement, Mr. Murray will continue to serve in his current roles as an Executive Vice President of RMR LLC and as an officer and director of Sonesta until March 31, 2026, at which time he will resign from such offices and from any other officer or related positions within RMR LLC, Sonesta, any RMR LLC managed company or any of their affiliates. Mr. Murray will continue to serve as an employee of Sonesta until September 30, 2026. Under the Murray Retirement Agreement, Mr. Murray is eligible to receive certain payments and benefits following his resignation from these positions.

Pursuant to each of the Clark Retirement Agreement and the Murray Retirement Agreement, RMR LLC has agreed to recommend that the Compensation Committee approve the acceleration of each of Ms. Clark's and Mr. Murray's unvested Class A Common Shares, effective as of such person's retirement date.

#### Accounting and Tax Considerations
Our Compensation Committee takes note of the tax and accounting consequences of the compensation program for our named executive officers; however, those consequences do not dictate our Compensation Committee's decisions, which are instead based on our Compensation Committee's view of our overall best interests.

(1) Equals the number of vesting Class A Common Shares multiplied by the closing price on the date that such Class A Common Shares vested in fiscal 2025.

(2) The number of Class A Common Shares shown in the table does not include Class A Common Shares awarded to Mr. Portnoy in his capacity as a Managing Director.

(3) The number of Class A Common Shares shown in the table does not include Class A Common Shares awarded to Ms. Clark in her capacity as a Managing Director.

### Potential Payments upon Termination or Change in Control
On September 9, 2025, our Compensation Committee approved awards of 35,587 Class A Common Shares to Mr. Portnoy, 17,793 Class A Common Shares to each of Mr. Jordan and Ms. Clark, and 8,896 Class A Common Shares to each of Messrs. Murray, Bilotto and Leer in their capacities as our executive officers. These awards were valued at $16.86 per Class A Common Share, the closing price of the Class A Common Shares on the Nasdaq on the date the awards were made under the Plan. The form of award agreement for each of these awards provides for vesting of the Class A Common Shares in five equal annual installments beginning on the date of the award and the Plan provides for acceleration of vesting of all share awards (including previously granted awards) upon the occurrence of certain change in control or employment termination events (each, a "Termination Event").

Unless accelerated in the discretion of the Compensation Committee, each Promote Interest allocated under the RMR Residential Promote Program vests upon the participant's termination of employment with the Company or its affiliates other than for cause based on length of service during the four-year period following the grant date—0% prior to the first anniversary of the grant date, 25% on or after the first but before the second anniversary of the grant date, 50% on or after the second but before the third anniversary of the grant date, 75% on or after the third but before the fourth anniversary of the grant date and 100% on or after the fourth anniversary of the grant date. Each participant in the RMR Residential Promote Program signs a participation agreement that contains certain restrictive covenants, including among others, non-solicitation and non-disparagement, and provides that interests are subject to forfeiture in certain circumstances, including without limitation, breach of covenants or termination of employment for cause.

(1) Equals the number of shares multiplied by the closing price per share of our Class A Common Shares on September 30, 2025 of $15.73.

(2) The amounts listed in this table do not reflect any amounts payable pursuant to the Clark Retirement Agreement or the Murray Retirement Agreement, as applicable.

### Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to disclose the median of the annual total compensation of our employees (excluding our principal executive officer), the annual total compensation of our principal executive officer, Mr. Portnoy, and the ratio of these two amounts.

For fiscal 2025, our last completed fiscal year:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the median of the annual total compensation of all employees of the Company (excluding Mr. Portnoy) was $96,984; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the annual total compensation of Mr. Portnoy, as reported in the Summary Compensation Table on page [37](#tSCT), was $4,817,047.

Based on this information, for fiscal 2025, the ratio of the annual total compensation of Mr. Portnoy to the median of the annual total compensation of all other employees was 49.67 to 1.

We identified the median employee by totaling (1) cash compensation (i.e., wages, overtime and bonus) as reflected in our payroll records for fiscal 2025 and (2) the value of Class A Common Shares that were awarded in fiscal 2025, for all individuals (excluding our Chief Executive Officer), who we employed on September 30, 2025 (whether on a full-time or part-time basis). In addition, we annualized the wages of full-time employees who were hired during fiscal 2025 but did not work for us the entire fiscal year. We did not make any other assumptions, adjustments, or estimates with respect to total cash compensation or stock compensation.

After identifying the median employee, we calculated annual total compensation for fiscal 2025 for the median employee using the same methodology we use for our named executive officers as set forth in the Summary Compensation Table.

We believe that the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Pay Versus Performance

The following table and footnotes summarize the total compensation we paid to our Named Executive Officers (our "NEOs"), compensation "actually paid" to the NEOs (calculated in accordance with SEC rules), the cumulative total shareholder return of the Company, the peer group total shareholder return and our net income for the past five fiscal years. We do not use any financial performance measures to link compensation actually paid to our NEOs by us to the Company's performance. Accordingly, pursuant to the SEC rules, we have not included a "company selected measure" or the tabular list of performance measures. For more information about the compensation we pay to our NEOs, please see "Compensation Discussion and Analysis" above.

For fiscal 2025, peer group total shareholder return is based on a self-constructed peer group composed of the following alternative asset management companies: Brookfield Corporation, Cohen & Steers Inc., Kennedy-Wilson Holdings Inc. and RITHM Capital Corp. As of September 2, 2025, Bridge Investment Group Holdings, Inc. is no longer publicly traded and, as a result, it was not included in calculation of the peer group total shareholder return.

PROPOSAL 3: RATIFICATION OF THE APPOINTMENT

OF DELOITTE & TOUCHE LLP AS INDEPENDENT AUDITORS

Our Audit Committee has the sole authority and responsibility to hire, evaluate and, when appropriate, replace our independent auditors and is directly responsible for the appointment, compensation and general oversight of the work of our independent auditors. Our Audit Committee is responsible for approving the audit and permissible non-audit services provided by our independent auditors and the associated fees.

Our Audit Committee evaluates the performance of our independent auditors annually and determines whether to re-engage the current independent auditors or consider other audit firms. In doing so, our Audit Committee considers the quality and efficiency of the services provided by the auditors, the auditors' technical expertise and knowledge of our operations and industry, the auditors' independence, the results of Public Company Accounting Oversight Board ("PCAOB") inspections and peer quality reviews of the auditors and the auditors' reputation in the marketplace. In connection with the mandated rotation of our independent auditors' lead engagement partner, our Audit Committee and its chair consider the selection of the new lead engagement partner identified by our independent auditors.

Based on this evaluation, our Audit Committee has appointed Deloitte & Touche LLP ("Deloitte") to serve as our independent auditors for the fiscal year ending September 30, 2026. Deloitte has served as our independent auditors since June 2020 and is considered by management and our Audit Committee to be well-qualified.

Our Audit Committee has determined to submit its selection of our independent auditors to our shareholders for ratification. This vote will ratify prior action by our Audit Committee and will not be binding upon our Audit Committee. However, our Audit Committee may reconsider its prior appointment of our independent auditors or consider the results of this vote when it determines who to appoint as our independent auditors in the future.

### Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditors
Our Audit Committee has established policies and procedures that are intended to control the services provided by our independent auditors and to monitor their continuing independence. Under these policies, our independent auditors may not undertake any services unless the engagement is specifically approved by our Audit Committee or the services are included within a category that has been approved by our Audit Committee. The maximum charge for services is established by our Audit Committee when the specific engagement or the category of services is approved. In certain circumstances, our management is required to notify our Audit Committee when approved services are undertaken and our Audit Committee or its Chair may approve amendments or modifications to the engagement or the maximum fees. Our internal audit group is responsible for reporting to our Audit Committee regarding compliance with these policies and procedures.

Our Audit Committee will not approve engagements of our independent auditors to perform non-audit services for us if doing so will cause our independent auditors to cease to be independent within the meaning of applicable SEC or Nasdaq rules. In other circumstances, our Audit Committee considers, among other things, whether our independent auditors are able to provide the required services in a more or less effective and efficient manner than other available service providers and whether the services are consistent with the PCAOB Rules.

All services for which we engaged Deloitte in fiscal 2025 and 2024 were approved by our Audit Committee. The total fees for audit and non-audit services provided by Deloitte in fiscal 2025 and 2024 are set forth above. Our Audit Committee approved the engagement of Deloitte in fiscal 2025 and 2024 to provide the non-audit services described above because it determined that Deloitte providing these services would not compromise its independence and that Deloitte's familiarity with our record keeping and accounting systems would permit the firm to provide these services with equal or higher quality, more quickly and at a lower cost than we could obtain comparable quality services from other providers. For fiscal 2024, there were no non-audit services provided to us by Deloitte other than with respect to our subscription to Deloitte's online accounting research application.

### Other Information
We have been advised by Deloitte that neither the firm, nor any member of the firm, has any material interest, direct or indirect, in any capacity in us or our subsidiaries.

One or more representatives of Deloitte will be present at our 2026 Annual Meeting. The representatives will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Ratification of the appointment of our independent auditors requires the affirmative vote of a majority of all the votes cast, in person or by proxy, at our 2026 Annual Meeting.

#### Our Board of Directors recommends a vote "FOR" the ratification of the appointment of Deloitte & Touche LLP as independent auditors.

REPORT OF OUR AUDIT COMMITTEE

In the course of the Audit Committee (our "Audit Committee") of the Board of Directors (our "Board of Directors") of The RMR Group Inc.'s oversight of our financial reporting process, our Audit Committee has: (i) reviewed and discussed with management the audited financial statements for the fiscal year ended September 30, 2025; (ii) discussed with Deloitte & Touche LLP, our independent auditors, the matters required to be discussed under Public Company Accounting Oversight Board ("PCAOB") Auditing Standard No. 1301; (iii) received the written disclosures and the letter from our auditors required by applicable requirements of the PCAOB regarding our independent auditors' communications with our Audit Committee concerning independence; (iv) discussed with our independent auditors their independence; and (v) considered whether the provision of non-audit services by our independent auditors is compatible with maintaining their independence and concluded that it is compatible at this time.

Based on the foregoing review and discussions, our Audit Committee recommended to our Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2025, for filing with the Securities and Exchange Commission.

FREQUENTLY ASKED QUESTIONS

### Proxy Materials and Voting Information
1. ### What is included in the proxy materials? What is a proxy statement and what is a proxy?
The proxy materials for our 2026 Annual Meeting include the Notice Regarding the Availability of Proxy Materials, Notice of 2026 Annual Meeting, this Proxy Statement and our Annual Report for the fiscal year ended September 30, 2025 (collectively, the "proxy materials"). If you request a paper copy of these materials, the proxy materials will also include a proxy card or voting instruction form.

A proxy statement is a document that SEC regulations require us to give you when we ask you to return a proxy designating individuals to vote on your behalf. A proxy is your legal designation of another person to vote the shares you own. That other person is called your proxy.

2. ### What is the difference between holding shares as a shareholder of record and as a beneficial owner?
If your shares are registered directly in your name with our registrar and transfer agent, Equiniti Shareowner Services, you are considered a shareholder of record of those shares. If you are a shareholder of record, you should receive only one notice or proxy card for all the Class A Common Shares you hold in certificate form and in book entry form.

If your shares are held in an account you own at a bank or brokerage firm or you hold shares through another nominee, you are considered the "beneficial owner" of those shares. If you are a beneficial owner, you will receive voting instruction information from the bank, broker or other nominee through which you own your Class A Common Shares.

If you hold some shares of record and some shares beneficially, you should receive a notice or proxy card for all the Class A Common Shares you hold of record and a separate voting instruction form for the shares from the bank, broker or other nominee through which you own Class A Common Shares.

3. ### What different methods can I use to vote?
**By Telephone or Internet.** All shareholders of record as of the close of business on January 8, 2026, the Record Date, can authorize a proxy to vote their shares by touchtone telephone by calling 1-800-690-6903, or through the internet at *www.proxyvote.com*, using the procedures and instructions described in your Notice Regarding the Availability of Proxy Materials or proxy card. Beneficial owners may authorize a proxy by telephone or internet if their bank, broker or other nominee makes those methods available, in which case the bank, broker or nominee will include the instructions with the proxy voting materials. To authorize a proxy by telephone or internet, you will need the 16 digit control number provided on your Notice Regarding the Availability of Proxy Materials, proxy card or voting instruction form. The telephone and internet proxy authorization procedures are designed to authenticate shareholder identities, to allow shareholders to authorize a proxy to vote their shares and to confirm that their instructions have been recorded properly. Proxies submitted by telephone or through the internet must be received by 11:59 p.m., Eastern Time, on March 25, 2026 or, if the meeting is postponed or adjourned to a later date, by 11:59 p.m., Eastern Time, on the day immediately preceding the date of the reconvened meeting.

**By Written Proxy.** All shareholders of record as of the close of business on the Record Date can also submit voting instructions by written proxy card. If you are a shareholder of record and receive a Notice Regarding the Availability of Proxy Materials, you may request a written proxy card by following the instructions included in the notice. If you are a beneficial owner, you may request a written proxy card or a voting instruction form from your bank, broker or other nominee. Proxies submitted by mail must be received by 11:59 p.m., Eastern Time, on March 25, 2026 or, if the meeting is postponed or adjourned to a later date, by 11:59 p.m., Eastern Time, on the day immediately preceding the date of the reconvened meeting.

Attendance at our 2026 Annual Meeting will not, by itself, revoke a duly executed proxy.

Beneficial owners who wish to change their votes should contact the organization that holds their shares.

4. ### Who may vote at our 2026 Annual Meeting?
Holders of record of any class of our Common Shares as of the close of business on the Record Date, or their duly authorized proxies may vote at the meeting. Holders of any class of our Common Shares will vote as a single class on all matters at the meeting.

5. ### What if I authorize a proxy and do not specify how my shares are to be voted?
If you submit a signed proxy card or authorize a proxy by internet or telephone, but do not indicate how your Common Shares should be voted on one or more proposals, then the proxies will vote your shares as our Board recommends on those proposals. Other than the proposals listed on pages [11](#tP1EO), [26](#tP2AV) and [47](#tP3RO), we do not know of any other matters to be presented at the meeting. If any other matters are properly presented at the meeting, the proxies may vote your shares in accordance with their discretion.

6. ### What is a quorum? How are abstentions, withheld votes and broker non-votes counted?
A quorum of shareholders is required for shareholders to take action at our 2026 Annual Meeting. The presence, in person or by proxy, of shareholders entitled to cast a majority of all the votes entitled to be cast at our 2026 Annual Meeting constitutes a quorum.

Abstentions and broker non-votes (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owner or the persons entitled to vote and (ii) the broker does not have discretionary voting power on a particular matter), if any, are included in determining whether a quorum is present. Abstentions are not votes cast and, therefore, will not be included in vote totals and will have no effect on the outcome of any Proposal to be acted upon at our 2026 Annual Meeting. A proxy marked "WITHHOLD

ALL" or "FOR ALL EXCEPT" with respect to Proposal 1 will have the same effect as an abstention for all nominees or for those nominees noted in the appropriate portion of the proxy card, respectively. Broker non-votes are not votes cast and, therefore, will not be included in vote totals and will have no effect on the outcome of Proposal 1 and Proposal 2. There can be no broker non-votes on Proposal 3 as it is a matter on which, if you hold your shares in street name and do not provide voting instructions to the broker, bank or other nominee that holds your shares, the nominee has discretionary authority to vote on your behalf.

7. ### Can I access the proxy materials on the internet? How can I sign up for the electronic proxy delivery service?
The Notice of 2026 Annual Meeting, this Proxy Statement and the Annual Report are available at *www.proxyvote.com*. You may access these proxy materials on the internet through the conclusion of our 2026 Annual Meeting.

Instead of receiving future copies of our proxy materials by mail, shareholders of record, as of the close of business on the Record Date, and most beneficial owners may elect to receive these materials electronically. Opting to receive your future proxy materials electronically will reduce the environmental impact of our annual meeting, save us the cost of printing and mailing documents, and also will give you an electronic link to our proxy voting site. Your Notice Regarding the Availability of Proxy Materials instructs you as to how you may request electronic delivery of future proxy materials.

8. ### How are proxies solicited and what is the cost?
We bear all expenses incurred in connection with the solicitation of proxies on behalf of the Company. We have engaged D.F. King & Co., Inc. ("D.F. King") to assist with the solicitation of proxies for an estimated fee of $15,000 plus reimbursement of expenses. We have agreed to indemnify D.F. King against certain liabilities arising out of our agreement with D.F. King. We will request banks, brokers and other nominees to forward proxy materials to the beneficial owners of Class A Common Shares and to obtain their voting instructions. We will reimburse those firms for their expenses of forwarding proxy materials

Proxies may also be solicited, without additional compensation, by our and our subsidiaries' directors, officers and employees, by mail, telephone or other electronic means or in person.

9. ### What is householding?
As permitted by the Exchange Act and our Bylaws, we may deliver to shareholders only one copy of the Notice Regarding the Availability of Proxy Materials, Notice of 2026 Annual Meeting, this Proxy Statement and the Annual Report to Shareholders residing at the same address, unless a shareholder at such address has notified us of such shareholder's desire to receive separate copies of those documents. This practice is known as "householding."

We will deliver a separate copy of any of those documents to you if you write to us at Investor Relations, The RMR Group Inc., Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458, or call us at (617) 796-8230. If you want to receive separate copies of our notices regarding the availability of proxy materials, notices of annual meetings, proxy statements and annual reports in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee, or you may contact us at the above address or telephone number.

### 2026 Annual Meeting Information

To provide all of our shareholders an opportunity to participate in our 2026 Annual Meeting, our 2026 Annual Meeting will be a virtual meeting of shareholders.

RELATED PERSON TRANSACTIONS

In this "Related Person Transactions" section, unless the context requires otherwise, references to "RMR Inc.," "we," "us" and "our" refer solely to The RMR Group Inc., a Maryland corporation, and not any of our subsidiaries. The description of agreements in this "Related Person Transactions" section do not purport to be complete and are subject to, and qualified in their entirety by, reference to the actual agreements, copies of certain of which are filed as exhibits to our Annual Report.

A "related person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which (i) we were, are or will be a participant, (ii) the amount involved exceeds $120,000 and (iii) any related person had, has or will have a direct or indirect material interest.

A "related person" means any person who is, or at any time since October 1, 2024 was:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a Director, a nominee for Director or an executive officer of us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • known to us to be the beneficial owner of more than 5% of the outstanding Common Shares when a transaction in which such person had a direct or indirect material interest occurred or existed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an immediate family member of any of the persons referenced in the preceding two bullets, which means any child, stepchild, parent, stepparent, spouse, sibling, mother in law, father in law, son in law, daughter in law, brother in law or sister in law of any of the persons referenced in the preceding two bullets, and any person (other than a tenant or employee) sharing the household of any of the persons referenced in the preceding two bullets; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a firm, corporation or other entity in which any of the foregoing persons is a partner or principal or in a similar position or in which such person has a 10% or greater beneficial ownership interest.

We have adopted written Governance Guidelines that contain guidelines for the consideration and approval of any related person transactions. Under these Governance Guidelines, neither we nor any of our subsidiaries may enter into a transaction in which any Director or executive officer, any member of the immediate family of any Director or executive officer or other related person, has or will have a direct or indirect material interest unless that transaction has been disclosed or made known to our Board and our Board reviews and approves or ratifies the transaction by the affirmative vote of a majority of the disinterested Directors, even if the disinterested Directors constitute less than a quorum. If there are no disinterested Directors, the transaction must be reviewed, authorized and approved or ratified by both (i) the affirmative vote of a majority of our Board and (ii) the affirmative vote of a majority of the Independent Directors (as such term is defined under Nasdaq rules). In determining whether to approve or ratify a transaction, our Board, or disinterested Directors or Independent Directors, as the case may be, must also act in accordance with any applicable provisions of our charter and Bylaws, consider all of the relevant facts and circumstances and approve only those transactions that they determine are fair and reasonable to us. All related person transactions described in Annex A to this Proxy Statement were reviewed and approved or ratified by a majority of the disinterested Directors or otherwise in accordance with our policies, as described above, and Maryland law. In the case of any transaction with us in which any other employee of us who is subject to the Code who has a direct or indirect material interest in the transaction, the employee must seek approval from an executive officer who has no interest in the matter for which approval is being requested. Copies of our Governance Guidelines and the Code are available on our website, *www.rmrgroup.com*.

Certain related person transactions are set forth in Annex A to this Proxy Statement.

We conduct substantially all of our business through our majority owned subsidiary, The RMR Group LLC ("RMR LLC"). We have no employees, and the personnel and various services we require to operate our business are or will be provided to us by RMR LLC. We serve as the managing member of RMR LLC and, as of January 8, 2026, we owned 16,058,177, class A membership units ("Class A Units") of RMR LLC and 1,000,000 class B membership units of RMR LLC.

As described in "Ownership of Our Equity Securities" in this Proxy Statement and in the Schedule 13G/A filed on February 7, 2024 by ABP Trust and Adam Portnoy, Mr. Portnoy and ABP Trust, in effect, own in aggregate a combined direct and indirect 50.7% economic interest in RMR LLC and control 91.0% of the voting power of our outstanding Common Shares.

Through our subsidiary, Tremont Realty Capital LLC ("Tremont"), an investment adviser registered with the Securities and Exchange Commission ("SEC"), we provide advisory services for a mortgage real estate investment trust, Seven Hills Realty Trust ("SEVN"). As of January 8, 2026, Tremont owned 20.3% of SEVN. The Managed Equity REITs and SEVN are collectively referred to as the Perpetual Capital clients.

Through RMR LLC, we provide management services to private capital vehicles, including ABP Trust, AlerisLife Inc., (including its subsidiaries, "AlerisLife") Sonesta International Hotels Corporation (including its subsidiaries, "Sonesta") and other private entities that own commercial and residential real estate, of which certain of our Managed Equity REITs and RMR LLC own minority equity interests. We refer to these private capital vehicles as the Private Capital clients.

Adam Portnoy is also the chair of the board of trustees and a managing trustee of each of the Managed Equity REITs and SEVN, and a director and the controlling shareholder of Sonesta (and its parent) and the sole director of AlerisLife. Mr. Jordan is a managing trustee of SEVN and was a managing trustee of ILPT until December 2025. Ms. Clark was a managing trustee of OPI and a director of Sonesta (and its parent) and previously served as the secretary of each Managed Equity REIT, SEVN, Sonesta and AlerisLife, in each case, until December 31, 2025. One of the executive officers of AlerisLife and one of the executive officers of Sonesta are officers or employees of RMR LLC. Our executive officers are also managing trustees of certain of the Perpetual Capital clients.

As of January 8, 2026, Adam Portnoy beneficially owned, in aggregate, 22.5% of SEVN's outstanding common shares (including through Tremont and ABP Trust); 9.8% of DHC's outstanding common shares (including through ABP Trust). In addition, Mr. Portnoy beneficially owns shares of ILPT, OPI and SVC comprising less than 5.0% of the outstanding shares of each of those respective companies.

The Managed Equity REITs and SEVN have no employees. RMR LLC provides or arranges for all the personnel, overhead and services required for the operation of the Managed Equity REITs pursuant to management agreements with them. All the officers of the Managed Equity REITs and ABP Trust are officers or employees of RMR LLC. All the officers, overhead and required office space of SEVN are provided or arranged by Tremont. All of SEVN's officers are officers or employees of Tremont or RMR LLC.

Several of our clients have historical and ongoing material relationships with other of our clients and several of the independent trustees of our public clients also serve as independent trustees or previously served as independent directors of other of our public clients. For example, as of January 8, 2026 SVC owned approximately 34% of the outstanding shares of Sonesta's parent, and DHC owns approximately 34% of the outstanding common stock of AlerisLife.

As of January 8, 2026, ILPT owned (i) a 22% equity interest in a joint venture and (ii) a 61% interest in a joint venture formed in February 2022 in connection with ILPT's acquisition of Monmouth Real Estate Investment Corporation.

venture for a life sciences property located in Boston, Massachusetts and (ii) a 20% equity interest in a joint venture for 10 medical office and life science properties. We provide management services to each of these joint ventures. Sonesta manages the majority of SVC's hotels, and most of the hotels Sonesta operates are owned by SVC. Prior to December 31, 2025 AlerisLife managed many of the senior living communities that DHC owns pursuant to long term agreements. On September 3, 2025, AlerisLife announced that it had entered into agreements to transition the management of its senior living communities to third party operators and expects to sell all of its assets and wind down its business and operations by June 30, 2026.

#### Share Awards by Our Public Clients
Our public clients annually award equity grants to certain of our Directors, officers and employees. During the fiscal year ended September 30, 2025, the compensation committees of the Managed Equity REITs, other than OPI, and SEVN awarded common shares directly to such persons in connection with their service as officers and employees of, or the provision of services to, those companies. Based on their grant date values, the aggregate value of such awards was as follows: $4,069,839 million from DHC; $2,379,989 million from ILPT; $4,082,323 million from SVC; and $1,653,248 million from SEVN. On occasion, our public clients have entered into arrangements with former employees of RMR LLC in connection with the termination of their employment with RMR LLC, providing for the acceleration of vesting of common shares previously awarded to them under the respective companies' equity compensation plan.

#### The Up-C Transaction
In connection with the 2015 transaction by which, among other things, DHC, OPI, Select Income REIT (now part of OPI) and SVC, the four then existing Managed Equity REITs, acquired 15,000,000 Class A Common Shares (the "Up-C Transaction") from us, we entered into a (i) registration rights agreement with ABP Trust pursuant to which we have granted ABP Trust certain demand and piggyback registration rights and (ii) a tax receivable agreement with ABP Trust. As of September 30, 2025, we had recorded a liability of $18.5 million payable to ABP Trust under the tax receivable agreement, which relates to our purchase of 15,000,000 class A membership units of RMR LLC in the Up-C Transaction. During the fiscal year ended September 30, 2025, we paid $2.4 million to ABP Trust pursuant to the tax receivable agreement.

We are also a party to the RMR LLC operating agreement which agreement governs the operations of RMR LLC and the rights and obligations of its members. Through our status as the managing member of RMR LLC, we exercise control over RMR LLC and are responsible for all operational and administrative decisions of RMR LLC and the day to day management of RMR LLC's business. For additional information regarding the registration rights agreement, the tax receivable agreement and the RMR LLC operating agreement, please see Annex A to our proxy statement for our 2024 annual meeting of shareholders.

#### Leases
As of September 30, 2025, we leased from ABP Trust and certain Managed Equity REITs office space for use as our headquarters and local offices. During the fiscal year ended September 30, 2025, we incurred rental expense pursuant to these leases aggregating $5.7 million. Generally, the rents RMR LLC pays the Managed Equity REITs were set at the average building rent for third party tenants in the same buildings at the time the leases were entered and the leases were approved by the independent trustees of the applicable Managed Equity REIT. The rents RMR LLC pays to ABP Trust were set based upon a survey of comparable market rents at the time the leases were entered. These leases have various termination dates and many have renewal options. Some of these leases are terminable on 30 days' notice and many allow RMR LLC to terminate early if RMR LLC's management agreements applicable to the buildings in which RMR leases space are terminated.

#### SEVN Rights Offering
On October 30, 2025, SEVN announced its intent to commence a transferable rights offering (the "Rights Offering") to raise gross proceeds of up to $65.0 million. We, through Tremont, agreed, pursuant to a backstop agreement, to participate in the Rights Offering by committing to (i) exercise our pro rata subscription rights based on our 11.3% ownership in SEVN and (ii) provide a backstop for the Rights Offering whereby we would purchase any additional SEVN common shares not otherwise sold in the Rights Offering, subject to the terms and conditions of the backstop agreement (the "Backstop Commitment"). Through the exercise of their respective basic subscription rights, Tremont purchased 854,029 SEVN common shares, Adam Portnoy purchased 109,669 SEVN common shares and ABP Trust purchased 58,266 SEVN common shares on December 4, 2025 in the Rights Offering. On December 11, 2025, pursuant to the Backstop Commitment, Tremont purchased 2,015,748 SEVN common shares that remained unsubscribed upon expiration of the Rights Offering. As of January 8, 2026, Tremont owned 4,577,835 SEVN common shares, or 20.3% of SEVN's outstanding common shares.

#### Sale of Loans
On November 10, 2025 we sold our two floating rate first mortgage loans secured by hotel and industrial properties in Revere, MA and Wayne, PA, respectively, for gross proceeds, excluding closing costs, of $61.7 million to SEVN.

#### Other
We entered into retirement agreements with certain of our former officers in connection with their retirements. Pursuant to these agreements, we made various cash payments and accelerated the vesting of unvested shares of RMR Inc. previously awarded to these retiring officers. We also enter into separation arrangements from time to time with other nonexecutive officers and employees of ours. For the fiscal year ended September 30, 2025, we recognized separation costs of $7.1 million in connection with the resignations and retirements of our executive officers.

We, DHC, ILPT, OPI, SVC and SEVN participate in a combined directors' and officers' liability insurance policy for primary coverage, including errors and omissions coverage for RMR LLC. We paid a premium of $0.1 million for this coverage for the policy years ending September 30, 2023, 2024 and 2025.

Pursuant to RMR LLC's management agreements with our clients, RMR LLC may from time to time negotiate on behalf of such entities with certain third party vendors and suppliers for the procurement of services to them. As part of this arrangement, these entities may enter agreements with RMR LLC and our clients for the purpose of obtaining more favorable terms from such vendors and suppliers.

We and our public clients have in the past held, and likely will in the future hold, business meetings at Sonesta operated hotels from time to time, and the directors, trustees, officers and employees of us and our public clients have in the past stayed, and are likely in the future to stay, overnight at Sonesta operated hotels when traveling for business. The applicable company pays Sonesta for the use of meeting space and related services and pays Sonesta or reimburses its directors, trustees, officers or employees for the costs of these hotel stays.

For more information about related person transactions, please see the proxy statements and periodic reports filed with the SEC by our public clients, i.e., DHC, ILPT, OPI, SVC, and SEVN.
