Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation All intercompany transactions and balances with or among our consolidated entities have been eliminated.
Use of Estimates	Use of Estimates Preparation of these financial statements in conformity with U.S. Generally Accepted Accounting Principles, or GAAP, requires our management to make certain estimates and assumptions that may affect the amounts reported in these consolidated financial statements and related notes. The actual results could differ from these estimates.
Revenue Recognition	Revenue Recognition Revenues from services we provide are recognized as earned over time as the services provided represent performance obligations that are satisfied over time. Management Agreements with the Managed Equity REITs We are party to a business management and a property management agreement with each Managed Equity REIT. The following is a summary of the fees we earn pursuant to our business management agreements with the Managed Equity REITs. For a summary of the fees we earn pursuant to our property management agreements with the Managed Equity REITs, see Property Management Agreements, below. Base Business Management Fees — We earn annual base business management fees from the Managed Equity REITs by providing continuous services pursuant to business management agreements equal to the lesser of: •the sum of (a) 0.5% of the historical cost of transferred real estate assets, if any, as defined in the applicable business management agreement, plus (b) 0.7% of the average invested capital (exclusive of the transferred real estate assets), as defined in the applicable business management agreement, up to $250,000, plus (c) 0.5% of the average invested capital exceeding $250,000; and •the sum of (a) 0.7% of the average market capitalization, as defined in the applicable business management agreement, up to $250,000, plus (b) 0.5% of the average market capitalization exceeding $250,000. The foregoing base business management fees are paid in cash monthly in arrears. For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate base business management fees from the Managed Equity REITs of $80,030, $84,182 and $85,603, respectively. Incentive Business Management Fees — We also may earn annual incentive business management fees from the Managed Equity REITs under the business management agreements. The incentive business management fees, which are payable in cash, are contingent performance based fees recognized only when earned at the end of each respective measurement period. Incentive business management fees are excluded from the transaction price until it becomes probable that there will not be a significant reversal of cumulative revenue recognized. The incentive business management fees are calculated for each Managed Equity REIT as 12.0% of the product of (a) the equity market capitalization of the Managed Equity REIT, as defined in the applicable business management agreement, on the last trading day of the year immediately prior to the relevant measurement period, and (b) the amount, expressed as a percentage, by which the Managed Equity REIT’s total return per share, as defined in the applicable business management agreement, exceeded the applicable benchmark total return per share, as defined in the applicable business management agreement, of a specified REIT index identified in the applicable business management agreement for the measurement period, as adjusted for net share issuances during the period and subject to caps on the values of the incentive fees. The measurement period for the annual incentive business management fees is defined as the three year period ending on December 31 of the year for which such fee is being calculated. We did not earn incentive business management fees from the Managed Equity REITs for calendar years 2024, 2023 or 2022. Term and Termination — Our management agreements with the Managed Equity REITs automatically extend on December 31st of each year and have terms thereafter that end on the 20th anniversary of the date of each extension. Each of the Managed Equity REITs has the right to terminate each management agreement: (i) at any time upon 60 days’ written notice for convenience, (ii) immediately upon written notice for cause, as defined in the agreements, (iii) upon written notice given within 60 days after the end of an applicable calendar year for a performance reason, as defined in the agreements, and (iv) by written notice during the 12 months following a change of control of RMR LLC, as defined in the agreements. We have the right to terminate the management agreements for good reason, as defined therein. Under our management agreements with the Managed Equity REITs, if a Managed Equity REIT terminates our management agreements for convenience, or if we terminate one or both of our management agreements with a Managed Equity REIT for good reason, the Managed Equity REIT is obligated to pay us a termination fee in an amount equal to the sum of the present values of the Managed Equity REIT’s monthly future fees, as defined therein, for the terminated management agreement(s) for the remaining term, assuming it had not been terminated. If a Managed Equity REIT terminates one or both of our management agreements for a performance reason, as defined therein, the Managed Equity REIT has agreed to pay to us the termination fee calculated as described above, but assuming a remaining term of 10 years. No termination fee is payable by a Managed Equity REIT if it terminates one or both of our management agreements for cause or as a result of a change of control of us, as defined in the applicable management agreement. OPI Management Agreement — OPI commenced voluntary chapter 11 petitions on October 30, 2025. In connection with this, we entered into a restructuring support agreement with OPI and certain of its lenders pursuant to which we have agreed to terms for a new management agreement and a new property management agreement with OPI, as set forth in the management agreement term sheet attached to the restructuring support agreement, which agreements are expected to take effect upon the effectiveness of OPI’s plan of reorganization. Pursuant to the management agreement term sheet, the initial term of the new management agreements will be five years and be terminable without penalty after two years, RMR LLC will be paid an annual fee under the new business management agreement of $14,000 payable per year for the first two years, and RMR LLC will be paid a 3% property management fee and a 5% construction supervision fee under the new property management agreement, consistent with the existing property management agreement. The current management agreements between OPI and RMR LLC will remain in effect during the pendency of the OPI chapter 11 cases, and RMR LLC will continue to manage OPI’s business in the ordinary course. Other Management Agreements We earn management fees by providing continuous services pursuant to the management agreements with ABP Trust regarding AlerisLife, with Sonesta, and until May 15, 2023, with TA, equal to 0.6% of: (i) in the case of AlerisLife, AlerisLife’s revenues from all sources reportable under GAAP, less any revenues reportable by AlerisLife with respect to properties for which it provides management services, plus the gross revenues at those properties determined in accordance with GAAP, payable in cash monthly in arrears; (ii) in the case of Sonesta, Sonesta’s estimated revenues from all sources reportable under GAAP, less any estimated revenues reportable by Sonesta with respect to hotels for which it provides management services, plus the estimated gross revenues at those hotels determined in accordance with GAAP, payable in cash monthly in advance; and (iii) in the case of TA, the sum of TA’s gross fuel margin, as defined in the applicable agreement, plus TA’s total nonfuel revenues, payable in cash monthly in advance. We also earn management fees from certain other Private Capital clients based on a percentage of average invested capital, as defined in the applicable management agreements. These management fees are payable in cash monthly in arrears. For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate base business management fees from TA and the Private Capital clients of $27,670, $27,575 and $36,815, respectively. Additionally, in connection with BP’s acquisition of TA on May 15, 2023, TA terminated its business management agreement with us and paid us the applicable termination fee of $45,282 which was recognized during the fiscal year ended September 30, 2023. Property Management Agreements We earn property management fees by providing continuous services pursuant to property management agreements with the Managed Equity REITs, SEVN, RMR Residential and certain Private Capital clients. We generally earn fees under these agreements between 2.5% to 3.5% of gross collected rents. Also, under the terms of the property management agreements, we receive additional fees for construction supervision services up to 5.0% of the cost of such construction. In addition, we earn fees under our RMR Residential property management agreements for providing certain marketing, information technology and other management services, as defined in the applicable management agreements, and the related costs are included in general and administrative expenses in our consolidated financial statements. These management fees are payable in cash monthly in arrears. For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate property management fees of $69,875, $76,444 and $63,153, respectively, including construction supervision fees of $9,314, $15,641 and $18,443, respectively. Management Agreements with Joint Ventures We enter into joint venture arrangements with the intent to acquire, improve and sell commercial real estate. We have management agreements with these joint ventures that entitle us to certain fees, such as property management and construction supervision fees and reimbursements of certain costs incurred on behalf of the joint ventures. Other applicable fees include: Acquisition Fees — We recognize revenue when the performance obligation related to the acquisition services is satisfied, typically at the closing of the real estate transaction. Acquisition fees are recorded in management services in our consolidated statements of comprehensive income. We recognized acquisition fee revenue of $664 for the fiscal year ended September 30, 2025. Carried Interest Revenues — For certain investments, through our subsidiaries, we invest alongside limited partners in investment vehicles and are entitled to a pro-rata share of their results, or a pro-rata allocation. In addition to a pro-rata allocation, and assuming certain investment returns are achieved, we are entitled to an outsized allocation of the income otherwise allocable to the limited partners, commonly referred to as a carried interest. We recognize carried interest in accordance with the performance-based fee arrangements outlined in our investment management agreements. Carried interest is recognized when the performance criteria specified in the agreements are met, typically upon the realization of investment gains that exceed a predetermined hurdle rate. The recognition of such revenues is contingent upon the achievement of both the investment return threshold and the requisite performance period. This ensures that the earnings process is substantially complete, the amount is reasonably estimable and it is no longer probable that there will be significant reversals. Given the unique nature of each fee arrangement and need for significant judgment, contracts with our clients are evaluated on an individual basis to determine the timing of revenue recognition. Accordingly, a portion of fees we recognize may be partially related to services performed in prior periods that meet recognition criteria in the current period. We did not recognize any carried interest revenues for the fiscal years ended September 30, 2025, 2024 and 2023. Management Agreements with Advisory Clients Tremont is primarily compensated pursuant to its management agreement with SEVN at an annual rate of 1.5% of equity, as defined in the applicable agreement. Tremont may also earn an incentive fee under its management agreement with SEVN equal to the difference between: (a) the product of (i) 20% and (ii) the difference between (A) core earnings, as defined in the applicable agreements, for the most recent 12 month period (or such lesser number of completed calendar quarters, if applicable), including the calendar quarter (or part thereof) for which the calculation of the incentive fee is being made, and (B) the product of (1) equity in the most recent 12 month period (or such lesser number of completed calendar quarters, if applicable), including the calendar quarter (or part thereof) for which the calculation of the incentive fee is being made, and (2) 7% per year and (b) the sum of any incentive fees paid to Tremont with respect to the first three calendar quarters of the most recent 12 month period (or such lesser number of completed calendar quarters preceding the applicable period, if applicable). No incentive fee shall be payable with respect to any calendar quarter unless core earnings for the 12 most recently completed calendar quarters in the aggregate is greater than zero. The incentive fee may not be less than zero. For the fiscal years ended September 30, 2025, 2024 and 2023, Tremont earned incentive fees of $653, $1,213 and $660, respectively. For the fiscal years ended September 30, 2025, 2024 and 2023, we earned advisory services revenue of $4,475, $4,506 and $4,520, respectively. Other Revenues Income from our loan investments related to our commercial real estate mortgage loans is generally accrued based on the coupon rates applied to the outstanding principal balance of such loans. Fees, premiums and discounts, if any, will be amortized or accreted into income from loan investments over the remaining term of such loans using the effective interest method, as adjusted for any prepayments. For the fiscal years ended September 30, 2025 and 2024, we earned income from loan investments, net of $2,447 and $1,313, respectively. Leases with our residential and retail tenants provide for base rent payments and may include variable payments or non-lease components, such as property level operating expenses reimbursed by our tenants as well as other required lease payments. We have made the policy election not to separate the lease and non-lease components because (i) the lease components are operating leases and (ii) the timing and pattern of recognition of non-lease components are the same as those of the lease components. Rental income from these operating leases is recognized on a straight line basis when collectability of substantially all of the lease payments is probable. For the fiscal years ended September 30, 2025 and 2024, we earned rental property revenues of $8,273 and $1,604, respectively. Reimbursable Costs We determined we control the services provided by third parties for certain of our clients and therefore account for the cost of these services and the related reimbursement revenue on a gross basis. Reimbursable Compensation and Benefits — Reimbursable compensation and benefits include reimbursements, at cost, that arise primarily from services our employees provide pursuant to our property management agreements at the properties of our clients. A significant portion of these compensation and benefits are charged or passed through to and paid by tenants of our clients. We recognize the revenue for reimbursements when we incur the related reimbursable compensation and benefits expense on behalf of our clients. Reimbursable Equity Based Compensation — Reimbursable equity based compensation includes awards of common shares by our clients directly to certain of our officers and employees in connection with the provision of management services to those clients. The revenue in respect of each award is based on the fair value as of the award date for those shares that have vested, with subsequent changes in the fair value of the unvested awards being recognized in our consolidated statements of comprehensive income over the requisite service periods. We record an equal, offsetting amount as equity based compensation expense for the value of these awards. Other Reimbursable Expenses — Other reimbursable expenses include reimbursements that arise from services we provide pursuant to our property management agreements, which include third party costs related to matters such as maintenance and repairs, development costs, security and cleaning services, a significant portion of which are charged or passed through to and paid by tenants of our clients.
Variable Interest Entities	Variable Interest Entities We regularly evaluate our relationships and investments to determine if they constitute variable interests. A variable interest is an investment or interest that will absorb portions of an entity’s expected losses or receive portions of an entity’s expected returns. If we determine we have a variable interest in an entity, we evaluate whether such interest is in a variable interest entity, or VIE. Under the VIE model, we would be required to consolidate a VIE we manage if we are determined to be the primary beneficiary of the entity. We continuously assess whether we must consolidate any of the entities we manage. Consideration of factors included, but was not limited to, our representation on the entity’s governing body, the size of our investment in each entity compared to the size of the entity and the size of other investors’ interests, the ability and rights to participate in significant policy making decisions and to replace the manager of those entities. Based on this assessment, we concluded that we are not required to consolidate the Managed Equity REITs, SEVN or our Private Capital Clients.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents, the majority of which is held at major commercial banks. Certain cash account balances exceed Federal Deposit Insurance Corporation insurance limits of $250,000 per account and, as a result, there is a concentration of credit risk related to amounts in excess of the insurance limits. We regularly monitor the financial stability of these financial institutions and believe that we are not exposed to any significant credit risk in cash and cash equivalents. As of September 30, 2025 and 2024, $1,802 and $553 in cash and cash equivalents consists of amounts escrowed for performance incentives, future real estate taxes, insurance and capital expenditures, as required by certain of our debt and other agreements. These funds are predominantly held by our mortgage lenders and are segregated from our cash accounts.
Loans Held for Investment, Net	Loans Held for Investment, Net Generally, our loans are classified as held for investment based upon our intent and ability to hold them until maturity. Loans that are held for investment are carried at cost, net of allowance for credit losses, unamortized loan origination fees, accreted exit fees, unamortized premiums and unaccreted discounts, as applicable, that are required to be recognized in the carrying value of the loans in accordance with GAAP, unless the loans are determined to be collateral dependent. Loans that we have a plan to sell or liquidate are held at the lower of cost or fair value less cost to sell. Loan Deferred Fees — Loan origination and exit fees are fees charged to our borrowers and unamortized or unaccreted balances are reflected as a reduction in loans held for investment, net, in our consolidated balance sheets. These fees are recorded as a component of loan investment interest income in our consolidated statements of comprehensive income over the life of the related loans held for investment.
Allowance for Credit Losses	Allowance for Credit Losses The measurement of current expected credit losses, or CECL, is based upon historical experience, current conditions, and reasonable and supportable forecasts incorporating forward-looking information that affect the collectability of the reported amount. Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments prescribes a forward-looking “expected loss” model that generally will result in the earlier recognition of credit losses and is applicable to financial assets measured at amortized cost and off-balance sheet credit exposures, such as unfunded loan commitments. The allowance for credit losses required under ASU No. 2016-13 is a valuation account that is deducted from the related loans’ amortized cost basis in our consolidated balance sheets. Our loans typically include commitments to fund incremental proceeds to borrowers over the life of the loan; these future funding commitments are also subject to the CECL model. The allowance for credit losses related to unfunded loan commitments is included in accounts payable and accrued expenses in our consolidated balance sheets. Given the lack of historical loss data related to our loan portfolio, we estimate our expected losses using an analytical model that considers the likelihood of default and loss given default for each individual loan. This analytical model incorporates data from a third party database with historical loan loss information for commercial mortgage-backed securities, or CMBS, and commercial real estate, or CRE, loans since 1998. We estimate the allowance for credit losses for our loan portfolio, including unfunded loan commitments, at the individual loan level. We utilize the model to estimate credit losses over a reasonable and supportable economic forecast period, followed by a straight-line reversion period to average historical losses. Average historical losses are established using a population of third party historical loss data that approximates our portfolio as of the measurement date. We evaluate the estimated allowance for each of our loans individually and we consider our internal loan risk rating as the primary credit quality indicator underlying our assessment. As of September 30, 2025 and 2024, based on our loan portfolio, the then current economic environment and expectations for future conditions, we recorded an allowance for credit losses of $589 and $343, respectively, with respect to our then outstanding loans held for investment and increasing accounts payable and accrued expenses by $49 and $259, respectively, with respect to our then unfunded loan commitments. We evaluate the credit quality of each of our loans at least quarterly by assessing a variety of risk factors in relation to each loan and assigning a risk rating to each loan based on those factors. Factors considered in these evaluations include, but are not limited to, property type, geographic and local market dynamics, physical condition, leasing and tenant profile, projected cash flow, risk of loss, current LTV, debt yield, collateral performance, structure, exit plan and sponsorship. Loans are rated “1” (less risk) through “5” (greater risk) as defined below: “1” lower risk—Criteria reflects a sponsor having a strong financial condition and low credit risk and our evaluation of management's experience; collateral performance exceeding performance metrics included in the business plan or credit underwriting; and the property demonstrating stabilized occupancy and/or market rates, resulting in strong current cash flow and net operating income and/or having a very low LTV. “2” average risk—Criteria reflects a sponsor having a stable financial condition and our evaluation of management's experience; collateral performance meeting or exceeding substantially all performance metrics included in the business plan or credit underwriting; and the property demonstrating improved occupancy at market rents, resulting in sufficient current cash flow and/or having a low LTV. “3” acceptable risk—Criteria reflects a sponsor having a history of repaying loans at maturity and meeting its credit obligations and our evaluation of management's experience; collateral performance expected to meet performance metrics included in the business plan or credit underwriting; and the property having a moderate LTV. New loans and loans with a limited history will typically be assigned this rating and will be adjusted to other levels from time to time as appropriate. “4” higher risk—Criteria reflects a sponsor having a history of unresolved missed or late payments, maturity extensions and difficulty timely fulfilling its credit obligations and our evaluation of management's experience; collateral performance failing to meet the business plan or credit underwriting; the existence of a risk of default possibly leading to a loss and/or potential weaknesses that deserve management’s attention; and/or the property having a high LTV. “5” loss likely—Criteria reflects a very high risk of realizing a principal loss or having incurred a principal loss; a sponsor having a history of default payments, trouble fulfilling its credit obligations, deeds in lieu of foreclosures, and/or bankruptcies; collateral performance is significantly worse than performance metrics included in the business plan; loan covenants or performance milestones having been breached or not attained; timely exit via sale or refinancing being uncertain; and/or the property having a very high LTV. We also evaluate the credit quality of our accounts receivable and contract assets. We have estimated certain credit losses associated with recurring accounts receivable which we include as a reduction to due from related parties in our consolidated balance sheets. As of September 30, 2025, these amounts were not significant.
Deferred Financing Costs	Deferred Financing Costs Costs incurred in connection with our mortgage financings or secured financing facility are capitalized and recorded as a reduction to the related liability in our consolidated balance sheets. Costs incurred in connection with our $100,000 senior secured revolving credit facility, or our revolving credit facility, are capitalized and recorded as a reduction to prepaid and other current assets in our consolidated balance sheets. Deferred financing costs are amortized over the term of the financing agreement and are recorded in our consolidated statements of comprehensive income as a component of either: (i) income from loan investments, net for our secured financing facility or (ii) interest expense for our mortgage notes and our revolving credit facility.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation of building and furniture and equipment is computed using the straight line method over estimated useful lives ranging from three to 30 years. Depreciation for leasehold improvements is computed using the straight line method over the term of the lesser of their useful lives or related lease agreements. Capitalized software costs, information technology labor and other personnel costs, are depreciated using the straight line method over useful lives ranging between three and five years. We do not depreciate the allocated cost of land. We may engage independent real estate appraisal firms to provide market information and evaluations which are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determinations of useful lives. We allocate the purchase prices of our properties to land, buildings and improvements based on determinations of the relative fair values of these assets assuming the properties are vacant. We determine the fair value of each property using methods similar to those used by independent appraisers, which may involve estimated cash flows that are based on a number of factors, including capitalization rates and discount rates, among others. We allocate a portion of the purchase price of our properties to above market and below market leases based on the present value (using an interest rate which reflects the risks associated with acquired in place leases at the time each property was acquired by us) of the difference, if any, between (i) the contractual amounts to be paid pursuant to the acquired in place leases and (ii) our estimates of fair market lease rates for the corresponding leases, measured over a period equal to the terms of the respective leases. We allocate a portion of the purchase price to acquired in place leases and tenant relationships based upon market estimates to lease up the property based on the leases in place at the time of purchase. We allocate this aggregate value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant’s lease. However, we have not separated the value of tenant relationships from the value of acquired in place leases because such value and related amortization expense is immaterial to the accompanying consolidated financial statements. In making these allocations, we consider factors such as estimated carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs, such as leasing commissions, legal and other related expenses, to execute similar leases in current market conditions at the time a property was acquired by us. If the value of tenant relationships becomes material in the future, we may separately allocate those amounts and amortize the allocated amounts over the estimated life of the relationships. For transactions that qualify as business combinations, we allocate the excess, if any, of the consideration over the fair value of the assets acquired to goodwill. We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. Impairment indicators may include declining tenant occupancy, lack of progress releasing vacant space, low long term prospects for improvement in property performance, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. The future net undiscounted cash flows are subjective and are based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining useful lives of our long lived assets. If we change our estimate of the remaining useful lives, we allocate the carrying value of the affected assets over their revised remaining useful lives.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the costs of business acquisitions in excess of the fair value of identifiable net assets acquired. We evaluate the recoverability of goodwill annually, or more frequently, if events or changes in circumstances indicate that goodwill might be impaired. If our review indicates that the carrying amount of goodwill exceeds its fair value, we would reduce the carrying amount of goodwill to fair value. As of September 30, 2025 and 2024, the gross carrying amount of goodwill in our consolidated balance sheets was $71,761 and no goodwill impairments were recorded.
Equity-Based Compensation	Equity-Based Compensation The awards made under our share award plan to our Directors, officers and employees to date, have been shares of Class A common stock of RMR Inc., or Class A Common Shares. Shares issued to Directors vest immediately. Shares issued to our officers and employees vest in five equal, consecutive, annual installments, with the first installment vesting on the date of award. We recognize share forfeitures as they occur. Compensation expense related to share awards is determined based on the market value of our shares on the date of award, with the aggregate value of the awarded shares amortized to expense over the related vesting period. Expense recognized for shares awarded to Directors are included in general and administrative expenses and for shares awarded to employees are included in equity based compensation expenses in our consolidated statements of comprehensive income.
Transaction and Acquisition Related Costs	Transaction and Acquisition Related Costs Transaction and acquisition related costs include costs related to acquisitions and other strategic transactions. Such costs include legal, accounting, valuation, other professional or consulting fees. Transaction and acquisition related costs are expensed as incurred.
Derivatives and Hedging Activities	Derivatives and Hedging Activities We account for our derivative instruments at fair value. Accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative instrument and the designation of the derivative instrument. The change in fair value of the effective portion of the derivative instrument that is not designated as a hedge or does not meet the hedge accounting criteria is recorded as a gain or loss to operations in our consolidated statements of comprehensive income. For more information on our derivative instruments and their fair values, see Note 7, Derivatives and Hedging Activities and Note 9, Fair Value of Financial Instruments.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Segments. On November 27, 2023, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, or ASU No. 2023-07, which requires public entities to: i) provide disclosures of significant segment expenses and other segment items if they are regularly provided to the chief operating decision maker, or CODM, and included in each reported measure of segment profit or loss; ii) provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Accounting Standards Codification, or ASC, 280, Segment Reporting, or ASC 280, in interim periods; and iii) disclose the CODM’s title and position, as well as an explanation of how the CODM uses the reported measures and other disclosures. Public entities with a single reportable segment must apply all the disclosure requirements of ASU No. 2023-07, as well as all the existing segment disclosures under ASC 280. The amendments in ASU No. 2023-07 are incremental to the requirements in ASC 280 and do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. We adopted ASU No. 2023-07 effective September 30, 2025, and as a result, we have included additional information related to the required disclosures in Note 16, Segment Reporting. Income Taxes. On December 14, 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, or ASU No. 2023-09, which requires public entities to enhance its annual income tax disclosures by requiring: i) consistent categories and greater disaggregation of information in the rate reconciliation, and ii) income taxes paid disaggregated by jurisdiction. The implementation of this ASU will not have a material impact on our consolidated financial statements and we will apply the requirements of ASU No. 2023-09 for our fiscal year ending September 30, 2026. Comprehensive Income. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statements Expenses, which requires public entities to disclose specific expense categories such as employee compensation, depreciation and intangible asset amortization. These details must be presented in a tabular format in the notes to financial statements for both interim and annual reporting periods. ASU No. 2024-03 is required to be applied prospectively but can be applied retrospectively, and is effective for the first annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact that ASU No. 2024-03 will have on our consolidated financial statements. Derivatives and Hedging. In September 2025, the FASB issued ASU No. 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606), which clarifies the application of derivative accounting to certain contracts and updates the guidance for share-based noncash consideration received from a customer in exchange for goods and services. Specifically, this ASU stipulates that entities should apply the guidance in Topic 606 to contracts with share-based noncash consideration from a customer unless and until the entity’s right to receive or retain the share-based noncash consideration is unconditional. ASU No. 2025-07 is effective for the first annual reporting periods beginning after December 15, 2026 and interim reporting periods within those first annual reporting periods, with early adoption permitted. We are currently evaluating the impact that ASU No. 2025-07 will have on our consolidated financial statements. Internal Use Software. In September 2025, the FASB issued ASU No. 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which requires companies to start capitalizing eligible software costs when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. ASU No. 2025-06 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are currently evaluating the impact that ASU No. 2025-06 will have on our consolidated financial statements.

Revenues from services we provide are recognized as earned over time as the services provided represent performance obligations that are satisfied over time.

Management Agreements with the Managed Equity REITs

We are party to a business management and a property management agreement with each Managed Equity REIT. The following is a summary of the fees we earn pursuant to our business management agreements with the Managed Equity REITs. For a summary of the fees we earn pursuant to our property management agreements with the Managed Equity REITs, see Property Management Agreements, below.

Base Business Management Fees — We earn annual base business management fees from the Managed Equity REITs by providing continuous services pursuant to business management agreements equal to the lesser of:

•the sum of (a) 0.5% of the historical cost of transferred real estate assets, if any, as defined in the applicable business management agreement, plus (b) 0.7% of the average invested capital (exclusive of the transferred real estate assets), as defined in the applicable business management agreement, up to $250,000, plus (c) 0.5% of the average invested capital exceeding $250,000; and

•the sum of (a) 0.7% of the average market capitalization, as defined in the applicable business management agreement, up to $250,000, plus (b) 0.5% of the average market capitalization exceeding $250,000.

The foregoing base business management fees are paid in cash monthly in arrears.

For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate base business management fees from the Managed Equity REITs of $80,030, $84,182 and $85,603, respectively.

Incentive Business Management Fees — We also may earn annual incentive business management fees from the Managed Equity REITs under the business management agreements. The incentive business management fees, which are payable in cash, are contingent performance based fees recognized only when earned at the end of each respective measurement period. Incentive business management fees are excluded from the transaction price until it becomes probable that there will not be a significant reversal of cumulative revenue recognized.

The incentive business management fees are calculated for each Managed Equity REIT as 12.0% of the product of (a) the equity market capitalization of the Managed Equity REIT, as defined in the applicable business management agreement, on the last trading day of the year immediately prior to the relevant measurement period, and (b) the amount, expressed as a percentage, by which the Managed Equity REIT’s total return per share, as defined in the applicable business management agreement, exceeded the applicable benchmark total return per share, as defined in the applicable business management agreement, of a specified REIT index identified in the applicable business management agreement for the measurement period, as adjusted for net share issuances during the period and subject to caps on the values of the incentive fees. The measurement period for the annual incentive business management fees is defined as the three year period ending on December 31 of the year for which such fee is being calculated.

We did not earn incentive business management fees from the Managed Equity REITs for calendar years 2024, 2023 or 2022.

Term and Termination — Our management agreements with the Managed Equity REITs automatically extend on December 31st of each year and have terms thereafter that end on the 20th anniversary of the date of each extension. Each of the Managed Equity REITs has the right to terminate each management agreement: (i) at any time upon 60 days’ written notice for convenience, (ii) immediately upon written notice for cause, as defined in the agreements, (iii) upon written notice given within 60 days after the end of an applicable calendar year for a performance reason, as defined in the agreements, and (iv) by written notice during the 12 months following a change of control of RMR LLC, as defined in the agreements. We have the right to terminate the management agreements for good reason, as defined therein.

Under our management agreements with the Managed Equity REITs, if a Managed Equity REIT terminates our management agreements for convenience, or if we terminate one or both of our management agreements with a Managed Equity REIT for good reason, the Managed Equity REIT is obligated to pay us a termination fee in an amount equal to the sum of the present values of the Managed Equity REIT’s monthly future fees, as defined therein, for the terminated management agreement(s) for the remaining term, assuming it had not been terminated. If a Managed Equity REIT terminates one or both of our management agreements for a performance reason, as defined therein, the Managed Equity REIT has agreed to pay to us the termination fee calculated as described above, but assuming a remaining term of 10 years. No termination fee is payable by a Managed Equity REIT if it terminates one or both of our management agreements for cause or as a result of a change of control of us, as defined in the applicable management agreement.

OPI Management Agreement — OPI commenced voluntary chapter 11 petitions on October 30, 2025. In connection with this, we entered into a restructuring support agreement with OPI and certain of its lenders pursuant to which we have agreed to terms for a new management agreement and a new property management agreement with OPI, as set forth in the management agreement term sheet attached to the restructuring support agreement, which agreements are expected to take effect upon the effectiveness of OPI’s plan of reorganization. Pursuant to the management agreement term sheet, the initial term of the new management agreements will be five years and be terminable without penalty after two years, RMR LLC will be paid an annual fee under the new business management agreement of $14,000 payable per year for the first two years, and RMR LLC will be paid a 3% property management fee and a 5% construction supervision fee under the new property management agreement, consistent with the existing property management agreement. The current management agreements between OPI and RMR LLC will remain in effect during the pendency of the OPI chapter 11 cases, and RMR LLC will continue to manage OPI’s business in the ordinary course.

Other Management Agreements

We earn management fees by providing continuous services pursuant to the management agreements with ABP Trust regarding AlerisLife, with Sonesta, and until May 15, 2023, with TA, equal to 0.6% of: (i) in the case of AlerisLife, AlerisLife’s revenues from all sources reportable under GAAP, less any revenues reportable by AlerisLife with respect to properties for which it provides management services, plus the gross revenues at those properties determined in accordance with GAAP, payable in cash monthly in arrears; (ii) in the case of Sonesta, Sonesta’s estimated revenues from all sources reportable under GAAP, less any estimated revenues reportable by Sonesta with respect to hotels for which it provides management services, plus the estimated gross revenues at those hotels determined in accordance with GAAP, payable in cash monthly in advance; and (iii) in the case of TA, the sum of TA’s gross fuel margin, as defined in the applicable agreement, plus TA’s total nonfuel revenues, payable in cash monthly in advance.

We also earn management fees from certain other Private Capital clients based on a percentage of average invested capital, as defined in the applicable management agreements. These management fees are payable in cash monthly in arrears.

For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate base business management fees from TA and the Private Capital clients of $27,670, $27,575 and $36,815, respectively. Additionally, in connection with BP’s acquisition of TA on May 15, 2023, TA terminated its business management agreement with us and paid us the applicable termination fee of $45,282 which was recognized during the fiscal year ended September 30, 2023.

Property Management Agreements

We earn property management fees by providing continuous services pursuant to property management agreements with the Managed Equity REITs, SEVN, RMR Residential and certain Private Capital clients. We generally earn fees under these agreements between 2.5% to 3.5% of gross collected rents. Also, under the terms of the property management agreements, we receive additional fees for construction supervision services up to 5.0% of the cost of such construction. In addition, we earn fees under our RMR Residential property management agreements for providing certain marketing, information technology and

other management services, as defined in the applicable management agreements, and the related costs are included in general and administrative expenses in our consolidated financial statements. These management fees are payable in cash monthly in arrears.

For the fiscal years ended September 30, 2025, 2024 and 2023, we earned aggregate property management fees of $69,875, $76,444 and $63,153, respectively, including construction supervision fees of $9,314, $15,641 and $18,443, respectively.

Management Agreements with Joint Ventures

We enter into joint venture arrangements with the intent to acquire, improve and sell commercial real estate. We have management agreements with these joint ventures that entitle us to certain fees, such as property management and construction supervision fees and reimbursements of certain costs incurred on behalf of the joint ventures. Other applicable fees include:

Acquisition Fees — We recognize revenue when the performance obligation related to the acquisition services is satisfied, typically at the closing of the real estate transaction. Acquisition fees are recorded in management services in our consolidated statements of comprehensive income. We recognized acquisition fee revenue of $664 for the fiscal year ended September 30, 2025.

Carried Interest Revenues — For certain investments, through our subsidiaries, we invest alongside limited partners in investment vehicles and are entitled to a pro-rata share of their results, or a pro-rata allocation. In addition to a pro-rata allocation, and assuming certain investment returns are achieved, we are entitled to an outsized allocation of the income otherwise allocable to the limited partners, commonly referred to as a carried interest. We recognize carried interest in accordance with the performance-based fee arrangements outlined in our investment management agreements. Carried interest is recognized when the performance criteria specified in the agreements are met, typically upon the realization of investment gains that exceed a predetermined hurdle rate. The recognition of such revenues is contingent upon the achievement of both the investment return threshold and the requisite performance period. This ensures that the earnings process is substantially complete, the amount is reasonably estimable and it is no longer probable that there will be significant reversals. Given the unique nature of each fee arrangement and need for significant judgment, contracts with our clients are evaluated on an individual basis to determine the timing of revenue recognition. Accordingly, a portion of fees we recognize may be partially related to services performed in prior periods that meet recognition criteria in the current period. We did not recognize any carried interest revenues for the fiscal years ended September 30, 2025, 2024 and 2023.

Management Agreements with Advisory Clients

Tremont is primarily compensated pursuant to its management agreement with SEVN at an annual rate of 1.5% of equity, as defined in the applicable agreement. Tremont may also earn an incentive fee under its management agreement with SEVN equal to the difference between: (a) the product of (i) 20% and (ii) the difference between (A) core earnings, as defined in the applicable agreements, for the most recent 12 month period (or such lesser number of completed calendar quarters, if applicable), including the calendar quarter (or part thereof) for which the calculation of the incentive fee is being made, and (B) the product of (1) equity in the most recent 12 month period (or such lesser number of completed calendar quarters, if applicable), including the calendar quarter (or part thereof) for which the calculation of the incentive fee is being made, and (2) 7% per year and (b) the sum of any incentive fees paid to Tremont with respect to the first three calendar quarters of the most recent 12 month period (or such lesser number of completed calendar quarters preceding the applicable period, if applicable). No incentive fee shall be payable with respect to any calendar quarter unless core earnings for the 12 most recently completed calendar quarters in the aggregate is greater than zero. The incentive fee may not be less than zero. For the fiscal years ended September 30, 2025, 2024 and 2023, Tremont earned incentive fees of $653, $1,213 and $660, respectively.

For the fiscal years ended September 30, 2025, 2024 and 2023, we earned advisory services revenue of $4,475, $4,506 and $4,520, respectively.

Other Revenues

Income from our loan investments related to our commercial real estate mortgage loans is generally accrued based on the coupon rates applied to the outstanding principal balance of such loans. Fees, premiums and discounts, if any, will be amortized or accreted into income from loan investments over the remaining term of such loans using the effective interest method, as adjusted for any prepayments. For the fiscal years ended September 30, 2025 and 2024, we earned income from loan investments, net of $2,447 and $1,313, respectively.

Leases with our residential and retail tenants provide for base rent payments and may include variable payments or non-lease components, such as property level operating expenses reimbursed by our tenants as well as other required lease payments. We have made the policy election not to separate the lease and non-lease components because (i) the lease components are operating leases and (ii) the timing and pattern of recognition of non-lease components are the same as those of the lease components. Rental income from these operating leases is recognized on a straight line basis when collectability of substantially all of the lease payments is probable. For the fiscal years ended September 30, 2025 and 2024, we earned rental property revenues of $8,273 and $1,604, respectively.

Reimbursable Costs

We determined we control the services provided by third parties for certain of our clients and therefore account for the cost of these services and the related reimbursement revenue on a gross basis.

Reimbursable Compensation and Benefits — Reimbursable compensation and benefits include reimbursements, at cost, that arise primarily from services our employees provide pursuant to our property management agreements at the properties of our clients. A significant portion of these compensation and benefits are charged or passed through to and paid by tenants of our clients. We recognize the revenue for reimbursements when we incur the related reimbursable compensation and benefits expense on behalf of our clients.

Reimbursable Equity Based Compensation — Reimbursable equity based compensation includes awards of common shares by our clients directly to certain of our officers and employees in connection with the provision of management services to those clients. The revenue in respect of each award is based on the fair value as of the award date for those shares that have vested, with subsequent changes in the fair value of the unvested awards being recognized in our consolidated statements of comprehensive income over the requisite service periods. We record an equal, offsetting amount as equity based compensation expense for the value of these awards.

Other Reimbursable Expenses — Other reimbursable expenses include reimbursements that arise from services we provide pursuant to our property management agreements, which include third party costs related to matters such as maintenance and repairs, development costs, security and cleaning services, a significant portion of which are charged or passed through to and paid by tenants of our clients.

Variable Interest Entities

We regularly evaluate our relationships and investments to determine if they constitute variable interests. A variable interest is an investment or interest that will absorb portions of an entity’s expected losses or receive portions of an entity’s expected returns. If we determine we have a variable interest in an entity, we evaluate whether such interest is in a variable interest entity, or VIE. Under the VIE model, we would be required to consolidate a VIE we manage if we are determined to be the primary beneficiary of the entity. We continuously assess whether we must consolidate any of the entities we manage. Consideration of factors included, but was not limited to, our representation on the entity’s governing body, the size of our investment in each entity compared to the size of the entity and the size of other investors’ interests, the ability and rights to participate in significant policy making decisions and to replace the manager of those entities. Based on this assessment, we concluded that we are not required to consolidate the Managed Equity REITs, SEVN or our Private Capital Clients.

Cash and Cash Equivalents

We consider highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents, the majority of which is held at major commercial banks. Certain cash account balances exceed Federal Deposit Insurance Corporation insurance limits of $250,000 per account and, as a result, there is a concentration of credit risk related to amounts in excess of the insurance limits. We regularly monitor the financial stability of these financial institutions and believe that we are not exposed to any significant credit risk in cash and cash equivalents.

As of September 30, 2025 and 2024, $1,802 and $553 in cash and cash equivalents consists of amounts escrowed for performance incentives, future real estate taxes, insurance and capital expenditures, as required by certain of our debt and other agreements. These funds are predominantly held by our mortgage lenders and are segregated from our cash accounts.

Loans Held for Investment, Net

Generally, our loans are classified as held for investment based upon our intent and ability to hold them until maturity. Loans that are held for investment are carried at cost, net of allowance for credit losses, unamortized loan origination fees, accreted exit fees, unamortized premiums and unaccreted discounts, as applicable, that are required to be recognized in the carrying value of the loans in accordance with GAAP, unless the loans are determined to be collateral dependent. Loans that we have a plan to sell or liquidate are held at the lower of cost or fair value less cost to sell.

Loan Deferred Fees — Loan origination and exit fees are fees charged to our borrowers and unamortized or unaccreted balances are reflected as a reduction in loans held for investment, net, in our consolidated balance sheets. These fees are recorded as a component of loan investment interest income in our consolidated statements of comprehensive income over the life of the related loans held for investment.

Allowance for Credit Losses

The measurement of current expected credit losses, or CECL, is based upon historical experience, current conditions, and reasonable and supportable forecasts incorporating forward-looking information that affect the collectability of the reported amount. Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments prescribes a forward-looking “expected loss” model that generally will result in the earlier recognition of credit losses and is applicable to financial assets measured at amortized cost and off-balance sheet credit exposures, such as unfunded loan commitments.

The allowance for credit losses required under ASU No. 2016-13 is a valuation account that is deducted from the related loans’ amortized cost basis in our consolidated balance sheets. Our loans typically include commitments to fund incremental proceeds to borrowers over the life of the loan; these future funding commitments are also subject to the CECL model. The allowance for credit losses related to unfunded loan commitments is included in accounts payable and accrued expenses in our consolidated balance sheets.

Given the lack of historical loss data related to our loan portfolio, we estimate our expected losses using an analytical model that considers the likelihood of default and loss given default for each individual loan. This analytical model incorporates data from a third party database with historical loan loss information for commercial mortgage-backed securities, or CMBS, and commercial real estate, or CRE, loans since 1998. We estimate the allowance for credit losses for our loan portfolio, including unfunded loan commitments, at the individual loan level. We utilize the model to estimate credit losses over a reasonable and supportable economic forecast period, followed by a straight-line reversion period to average historical losses. Average historical losses are established using a population of third party historical loss data that approximates our portfolio as of the measurement date. We evaluate the estimated allowance for each of our loans individually and we consider our internal loan risk rating as the primary credit quality indicator underlying our assessment.

As of September 30, 2025 and 2024, based on our loan portfolio, the then current economic environment and expectations for future conditions, we recorded an allowance for credit losses of $589 and $343, respectively, with respect to our then outstanding loans held for investment and increasing accounts payable and accrued expenses by $49 and $259, respectively, with respect to our then unfunded loan commitments.

We evaluate the credit quality of each of our loans at least quarterly by assessing a variety of risk factors in relation to each loan and assigning a risk rating to each loan based on those factors. Factors considered in these evaluations include, but are not limited to, property type, geographic and local market dynamics, physical condition, leasing and tenant profile, projected cash

flow, risk of loss, current LTV, debt yield, collateral performance, structure, exit plan and sponsorship. Loans are rated “1” (less risk) through “5” (greater risk) as defined below:

“1” lower risk—Criteria reflects a sponsor having a strong financial condition and low credit risk and our evaluation of management's experience; collateral performance exceeding performance metrics included in the business plan or credit underwriting; and the property demonstrating stabilized occupancy and/or market rates, resulting in strong current cash flow and net operating income and/or having a very low LTV.

“2” average risk—Criteria reflects a sponsor having a stable financial condition and our evaluation of management's experience; collateral performance meeting or exceeding substantially all performance metrics included in the business plan or credit underwriting; and the property demonstrating improved occupancy at market rents, resulting in sufficient current cash flow and/or having a low LTV.

“3” acceptable risk—Criteria reflects a sponsor having a history of repaying loans at maturity and meeting its credit obligations and our evaluation of management's experience; collateral performance expected to meet performance metrics included in the business plan or credit underwriting; and the property having a moderate LTV. New loans and loans with a limited history will typically be assigned this rating and will be adjusted to other levels from time to time as appropriate.

“4” higher risk—Criteria reflects a sponsor having a history of unresolved missed or late payments, maturity extensions and difficulty timely fulfilling its credit obligations and our evaluation of management's experience; collateral performance failing to meet the business plan or credit underwriting; the existence of a risk of default possibly leading to a loss and/or potential weaknesses that deserve management’s attention; and/or the property having a high LTV.

“5” loss likely—Criteria reflects a very high risk of realizing a principal loss or having incurred a principal loss; a sponsor having a history of default payments, trouble fulfilling its credit obligations, deeds in lieu of foreclosures, and/or bankruptcies; collateral performance is significantly worse than performance metrics included in the business plan; loan covenants or performance milestones having been breached or not attained; timely exit via sale or refinancing being uncertain; and/or the property having a very high LTV.

We also evaluate the credit quality of our accounts receivable and contract assets. We have estimated certain credit losses associated with recurring accounts receivable which we include as a reduction to due from related parties in our consolidated balance sheets. As of September 30, 2025, these amounts were not significant.

Deferred Financing Costs

Costs incurred in connection with our mortgage financings or secured financing facility are capitalized and recorded as a reduction to the related liability in our consolidated balance sheets. Costs incurred in connection with our $100,000 senior secured revolving credit facility, or our revolving credit facility, are capitalized and recorded as a reduction to prepaid and other current assets in our consolidated balance sheets. Deferred financing costs are amortized over the term of the financing agreement and are recorded in our consolidated statements of comprehensive income as a component of either: (i) income from loan investments, net for our secured financing facility or (ii) interest expense for our mortgage notes and our revolving credit facility.

Property and Equipment

Property and equipment are stated at cost. Depreciation of building and furniture and equipment is computed using the straight line method over estimated useful lives ranging from three to 30 years. Depreciation for leasehold improvements is computed using the straight line method over the term of the lesser of their useful lives or related lease agreements. Capitalized software costs, information technology labor and other personnel costs, are depreciated using the straight line method over useful lives ranging between three and five years. We do not depreciate the allocated cost of land. We may engage independent real estate appraisal firms to provide market information and evaluations which are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determinations of useful lives.

We allocate the purchase prices of our properties to land, buildings and improvements based on determinations of the relative fair values of these assets assuming the properties are vacant. We determine the fair value of each property using methods similar to those used by independent appraisers, which may involve estimated cash flows that are based on a number of factors, including capitalization rates and discount rates, among others. We allocate a portion of the purchase price of our properties to above market and below market leases based on the present value (using an interest rate which reflects the risks associated with acquired in place leases at the time each property was acquired by us) of the difference, if any, between (i) the contractual amounts to be paid pursuant to the acquired in place leases and (ii) our estimates of fair market lease rates for the corresponding leases, measured over a period equal to the terms of the respective leases. We allocate a portion of the purchase price to acquired in place leases and tenant relationships based upon market estimates to lease up the property based on the leases in place at the time of purchase. We allocate this aggregate value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant’s lease. However, we have not separated the value of tenant relationships from the value of acquired in place leases because such value and related amortization expense is immaterial to the accompanying consolidated financial statements. In making these allocations, we consider factors such as estimated carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs, such as leasing commissions, legal and other related expenses, to execute similar leases in current market conditions at the time a property was acquired by us. If the value of tenant relationships becomes material in the future, we may separately allocate those amounts and amortize the allocated amounts over the estimated life of the relationships. For transactions that qualify as business combinations, we allocate the excess, if any, of the consideration over the fair value of the assets acquired to goodwill.

We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. Impairment indicators may include declining tenant occupancy, lack of progress releasing vacant space, low long term prospects for improvement in property performance, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. The future net undiscounted cash flows are subjective and are based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining useful lives of our long lived assets. If we change our estimate of the remaining useful lives, we allocate the carrying value of the affected assets over their revised remaining useful lives.

Goodwill and Intangible Assets

Goodwill represents the costs of business acquisitions in excess of the fair value of identifiable net assets acquired. We evaluate the recoverability of goodwill annually, or more frequently, if events or changes in circumstances indicate that goodwill might be impaired. If our review indicates that the carrying amount of goodwill exceeds its fair value, we would reduce the carrying amount of goodwill to fair value. As of September 30, 2025 and 2024, the gross carrying amount of goodwill in our consolidated balance sheets was $71,761 and no goodwill impairments were recorded.

Equity-Based Compensation

The awards made under our share award plan to our Directors, officers and employees to date, have been shares of Class A common stock of RMR Inc., or Class A Common Shares. Shares issued to Directors vest immediately. Shares issued to our officers and employees vest in five equal, consecutive, annual installments, with the first installment vesting on the date of award. We recognize share forfeitures as they occur. Compensation expense related to share awards is determined based on the market value of our shares on the date of award, with the aggregate value of the awarded shares amortized to expense over the related vesting period. Expense recognized for shares awarded to Directors are included in general and administrative expenses and for shares awarded to employees are included in equity based compensation expenses in our consolidated statements of comprehensive income.

Transaction and Acquisition Related Costs

Transaction and acquisition related costs include costs related to acquisitions and other strategic transactions. Such costs include legal, accounting, valuation, other professional or consulting fees. Transaction and acquisition related costs are expensed as incurred.

Derivatives and Hedging Activities

We account for our derivative instruments at fair value. Accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative instrument and the designation of the derivative instrument. The change in fair value of the effective portion of the derivative instrument that is not designated as a hedge or does not meet the hedge accounting criteria is recorded as a gain or loss to operations in our consolidated statements of comprehensive income. For more information on our derivative instruments and their fair values, see Note 7, Derivatives and Hedging Activities and Note 9, Fair Value of Financial Instruments.

Recent Accounting Pronouncements

Segments. On November 27, 2023, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, or ASU No. 2023-07, which requires public entities to: i) provide disclosures of significant segment expenses and other segment items if they are regularly provided to the chief operating decision maker, or CODM, and included in each reported measure of segment profit or loss; ii) provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Accounting Standards Codification, or ASC, 280, Segment Reporting, or ASC 280, in interim periods; and iii) disclose the CODM’s title and position, as well as an explanation of how the CODM uses the reported measures and other disclosures. Public entities with a single reportable segment must apply all the disclosure requirements of ASU No. 2023-07, as well as all the existing segment disclosures under ASC 280. The amendments in ASU No. 2023-07 are incremental to the requirements in ASC 280 and do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. We adopted ASU No. 2023-07 effective September 30, 2025, and as a result, we have included additional information related to the required disclosures in Note 16, Segment Reporting.

Income Taxes. On December 14, 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, or ASU No. 2023-09, which requires public entities to enhance its annual income tax disclosures by requiring: i) consistent categories and greater disaggregation of information in the rate reconciliation, and ii) income taxes paid disaggregated by jurisdiction. The implementation of this ASU will not have a material impact on our consolidated financial statements and we will apply the requirements of ASU No. 2023-09 for our fiscal year ending September 30, 2026.

Comprehensive Income. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statements Expenses, which requires public entities to disclose specific expense categories such as employee compensation, depreciation and intangible asset amortization. These details must be presented in a tabular format in the notes to financial statements for both interim and annual reporting periods. ASU No. 2024-03 is required to be applied prospectively but can be applied retrospectively, and is effective for the first annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact that ASU No. 2024-03 will have on our consolidated financial statements.

Derivatives and Hedging. In September 2025, the FASB issued ASU No. 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606), which clarifies the application of derivative accounting to certain contracts and updates the guidance for share-based noncash consideration received from a customer in exchange for goods and services. Specifically, this ASU stipulates that entities should apply the guidance in Topic 606 to contracts with share-based noncash consideration from a customer unless and until the entity’s right to receive or retain the share-based noncash consideration is unconditional. ASU No. 2025-07 is effective for the first annual reporting periods beginning after December 15, 2026 and interim reporting periods within those first annual reporting periods, with early adoption permitted. We are currently evaluating the impact that ASU No. 2025-07 will have on our consolidated financial statements.

Internal Use Software. In September 2025, the FASB issued ASU No. 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which requires companies to start capitalizing eligible software costs when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. ASU No. 2025-06 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are currently evaluating the impact that ASU No. 2025-06 will have on our consolidated financial statements.
