Basis of Presentation The accompanying condensed consolidated financial statements of Diversified Healthcare Trust and its subsidiaries, or DHC, we, us, or our, are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2024, or our Annual Report. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim period have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in our condensed consolidated financial statements include purchase price allocations, useful lives of fixed assets and impairments of real estate and intangible assets. We have been, are currently, and expect in the future to be involved in claims, lawsuits, and regulatory and other governmental audits, investigations and proceedings arising in the ordinary course of our business. While the outcome of any litigation is inherently uncertain, we do not believe any currently pending litigation or proceedings will have a material adverse effect on our financial condition, results of operations or cash flows. Note 2. Recent Accounting Pronouncements On December 14, 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , or ASU No. 2023-09, which requires public entities to enhance their 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. ASU No. 2023-09 should be applied prospectively but entities have the option to apply it retrospectively to all prior periods presented in the financial statements. ASU No. 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. We expect to include additional disclosures in the notes to our condensed consolidated financial statements as a result of the implementation of ASU No. 2023-09; however, these changes are not expected to have a material effect on our condensed consolidated financial statements. 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 , or ASU No. 2024-03, 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 condensed consolidated financial statements for both interim and annual reporting periods. ASU 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 2024-03 will have on our condensed consolidated financial statements. Note 3. Real Estate and Other Investments As of June 30, 2025, we owned 341 properties located in 34 states and Washington, D.C., including 21 properties classified as held for sale and one closed senior living community, and we owned an equity interest in each of two unconsolidated joint ventures that own medical office and life science properties located in five states. Dispositions: The table below represents the sale prices, excluding closing costs, of our dispositions for the six months ended June 30, 2025. We do not believe these sales represent a strategic shift in our business. As a result, the results of operations for these 6 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) properties are included in continuing operations through the date of sale of such properties in our condensed consolidated statements of comprehensive income (loss).

As of June 30, 2025, we had 21 properties classified as held for sale in our condensed consolidated balance sheet as follows: Segment Number of Properties Real Estate Properties, Net SHOP 15 $ 69,610 Medical Office and Life Science (1) 5 18,734 All Other 1 2,246 21 $ 90,590 (1) The net proceeds from the sale of two of these properties are required to be used to partially redeem our outstanding senior secured notes due 2026, if the sales of those properties are completed. We expect to sell these properties during the fourth quarter of 2025 for an aggregate sales price of $ 13,118 , excluding closing costs. Subsequent to June 30, 2025, we sold three properties for an aggregate sales price of $ 8,800 , excluding closing costs. As of August 1, 2025, we had 49 properties under agreements or letters of intent to sell for an aggregate sales price of $ 279,923 , excluding closing costs. The net proceeds from the sales of 11 of these properties, which have an expected aggregate sales price of $ 90,588 , excluding closing costs, are required to be used to partially redeem our outstanding senior secured notes due 2026, if the sales of such properties are completed. We may not complete the sales of any or all of the properties we currently plan to sell. Also, we may sell some or all of these properties at amounts that are less than currently expected and/or less than the carrying values of such properties, and we may incur losses on any such sales as a result. Impairment: We regularly evaluate our assets for indicators of impairment. Impairment indicators may include declining tenant or resident occupancy, weak or declining profitability from the property, decreasing tenant cash flows 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 an asset. If indicators of impairment are present, we evaluate the carrying value of the affected assets by comparing it to the expected future undiscounted cash flows to be generated from those assets. The future cash flows are subjective and are based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the asset to its estimated fair value. During the six months ended June 30, 2025, we recorded impairment charges of $ 52,266 to adjust the carrying value of 10 medical office properties to their estimated fair values. We sold one of these properties during the six months ended June 30, 2025. Four of these properties were classified as held for sale in our condensed consolidated balance sheet as of June 30, 2025. 7 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) Subsequent to June 30, 2025, we sold two of these 10 properties, and as of August 1, 2025, seven properties were under agreements or letters of intent to sell. During the six months ended June 30, 2025, we also recorded impairment charges of $ 17,199 to adjust the carrying value of 10 senior living communities in our senior housing operating portfolio, or SHOP, to their estimated fair values. These communities were classified as held for sale in our condensed consolidated balance sheet as of June 30, 2025.

Equity Method Investments in Unconsolidated Joint Ventures: As of June 30, 2025, we had equity investments in unconsolidated joint ventures as follows: Equity Method Investments in Joint Venture DHC Ownership DHC Carrying Value of Investment at June 30, 2025 Number of Properties State Square Feet Seaport Innovation LLC 10 % $ 94,415 1 MA 1,134,479 The LSMD Fund REIT LLC 20 % 44,736 10 CA, MA, NY, TX, WA 1,068,763 $ 139,151 11 2,203,242 8 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) The following table provides a summary of the mortgage debts of these joint ventures as of June 30, 2025: Joint Venture Coupon Rate Maturity Date Principal Balance (1) Mortgage Notes Payable (secured by one property in Massachusetts) (2) (3) 3.53 % 11/6/2028 $ 620,000 Mortgage Notes Payable (secured by nine properties in five states) (4) 3.46 % 2/11/2032 189,800 Mortgage Notes Payable (secured by one property in California) (4) (5) 6.21 % 2/9/2026 266,825 4.18 % $ 1,076,625 (1) Amounts are not adjusted for our minority equity interest. (2) We provide certain guaranties on this debt. (3) This mortgage loan requires interest-only payments until the anticipated repayment date on August 6, 2026, at which time all accrued and unpaid interest along with the principal balance of $ 620,000 is expected to be repaid. This mortgage loan matures on November 6, 2028 and any unpaid principal from the anticipated repayment date through the maturity date bears interest at a variable rate of the greater of 6.53 % or the then effective U.S. swap rate terminating on the maturity date plus 5.00 %. (4) The debt securing these properties is non-recourse to us. (5) The joint venture has one remaining one-year extension option for the maturity date of this mortgage loan, subject to satisfaction of certain conditions, and this mortgage loan requires that interest be paid at an annual rate of the one-month term secured overnight financing rate, or SOFR, plus a premium of 1.90 %. The joint venture has purchased an interest rate cap through February 2026 with a SOFR strike rate equal to 5.74 %. We account for the unconsolidated joint venture for 10 medical office and life science properties in which we own a 20 % equity interest, or the LSMD JV, and the unconsolidated joint venture for a life science property located in Boston, Massachusetts in which we own a 10 % equity interest, or the Seaport JV, using the equity method of accounting under the fair value option. We recognized changes in the fair value of our investments in our unconsolidated joint ventures of $ 2,654 and $( 21,493 ) during the three months ended June 30, 2025 and 2024, respectively, and $ 3,792 and $( 19,880 ) during the six months ended June 30, 2025 and 2024, respectively. These amounts are included in equity in net earnings (losses) of investees in our condensed consolidated statements of comprehensive income (loss). See Note 6 for further information regarding the valuation of our investment in these joint ventures. Equity Method Investment in AlerisLife: As of June 30, 2025, we owned approximately 34.0 % of the outstanding common shares of AlerisLife Inc., or AlerisLife. We do not control the activities that are most significant to AlerisLife and, as a result, we account for our non-controlling interest in AlerisLife using the equity method of accounting. As of June 30, 2025, our investment in AlerisLife had a carrying value of $ 8,418 . The cost basis of our investment in AlerisLife exceeded our proportionate share of AlerisLife's total stockholders' equity book value on the date of acquisition of our initial interest in AlerisLife, which was February 16, 2024, by an aggregate of $ 29,500 . As required under GAAP, we are amortizing this difference to equity in earnings of an investee over 21 years, the weighted average remaining useful life of the real estate assets owned by AlerisLife and the intangible contract asset with us as of the date of acquisition. We recorded amortization of the basis difference of $ 351 and $ 352 for the three months ended June 30, 2025 and 2024, respectively, and $ 702 and $ 526 for the six months ended June 30, 2025 and 2024, respectively.

These amounts are included in equity in net earnings (losses) of investees in our condensed consolidated statements of comprehensive income (loss). On February 14, 2025, AlerisLife paid an aggregate cash dividend of $ 50,000 to its stockholders.

See Note 11 for further information regarding our investment in AlerisLife. Other: In September 2022, certain of our managed senior living communities located in Florida experienced hurricane related damage. We carry comprehensive property, casualty, flood and business interruption insurances which covered our losses at these senior living communities, subject to a deductible. During the six months ended June 30, 2025, we recognized a gain on 9 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) insurance recoveries of $ 7,522 as a result of insurance proceeds received for these damaged senior living communities and the closing of the associated claim. Note 4. Leases We are a lessor of medical office and life science properties, senior living communities and other healthcare related properties. Our leases provide our tenants with the contractual right to use and economically benefit from all of the premises demised under the leases; therefore, we have determined to evaluate our leases as lease arrangements. Our leases provide for base rent payments and, in addition, may include variable payments. Rental income from operating leases, including any payments derived by index or market based indices, is recognized on a straight line basis over the lease term when we have determined that the collectability of substantially all of the lease payments is probable. Some of our leases have options to extend or terminate the lease exercisable at the option of our tenants, which are considered when determining the lease term. We decreased rental income to record revenue on a straight line basis by $ 146 for the three months ended June 30, 2025. We increased rental income to record revenue on a straight line basis by $ 309 for the six months ended June 30, 2025 and $ 656 and $ 947 for the three and six months ended June 30, 2024, respectively. Rents receivable, excluding receivables related to our properties classified as held for sale, if any, include $ 69,749 and $ 69,814 of straight line rent receivables at June 30, 2025 and December 31, 2024, respectively, and are included in other assets, net in our condensed consolidated balance sheets. We do not include in our measurement of our lease receivables certain variable payments, including changes in the index or market based indices after the inception of the lease, certain tenant reimbursements and other income until the specific events that trigger the variable payments have occurred. Such payments totaled $ 9,812 and $ 11,635 for the three months ended June 30, 2025 and 2024, respectively, of which tenant reimbursements totaled $ 9,768 and $ 11,586 , respectively, and $ 20,650 and $ 22,985 for the six months ended June 30, 2025 and 2024, respectively, of which tenant reimbursements totaled $ 20,191 and $ 22,870 , respectively. Right of Use Asset and Lease Liability: For leases where we are the lessee, we recognize a right of use asset and a lease liability equal to the present value of the minimum lease payments, with rental payments being applied to the lease liability and the right of use asset being amortized over the term of the lease. The values of the right of use assets and related liabilities representing our future obligation under the respective lease arrangements for which we are the lessee were $ 18,301 and $ 18,689 , respectively, as of June 30, 2025, and $ 20,025 and $ 20,411 , respectively, as of December 31, 2024. The right of use assets and related lease liabilities are included within other assets, net and other liabilities , respectively, within our condensed consolidated balance sheets. In addition, we lease equipment at certain of our managed senior living communities. These leases are short term in nature, are cancelable with no fee or do not result in an annual expense in excess of our capitalization policy and, as a result, are not recorded on our condensed consolidated balance sheets. 10 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) Note 5.

(3) We have a one-time option to extend the maturity date of these senior secured notes by one year , to January 15, 2027, subject to satisfaction of certain conditions and payment of an extension fee. If we exercise this option, interest payments will be due semiannually during the extension period at an initial interest rate of 11.25 % with increases of 50 basis points every 90 days these senior secured notes remain outstanding. (4) This mortgage loan requires that interest be paid at an annual rate of SOFR plus a premium of 2.50 % with interest-only payments through April 2027, and we have two six-month extension options of the interest-only period, subject to satisfaction of certain conditions. In connection with this mortgage loan, we have purchased an interest rate cap with a SOFR strike rate equal to 4.50 % pursuant to the terms of the applicable loan agreement. (5) These mortgage loans require interest-only payments through May 2030. (6) These mortgage loans require interest-only payments through June 2028.

As of August 1, 2025, we are under agreements or letters of intent to sell 11 additional properties that secure our senior secured notes due 2026 for an expected aggregate sales price of $ 90,588 , excluding closing costs. The net proceeds from these sales are required to be used to partially redeem these senior secured notes, if these sales are completed. Our senior secured notes due 2026 and the guarantees provided by the Collateral Guarantors are secured by a first priority lien and security interest in each of the collateral properties and 100 % of the equity interests in each of the Collateral Guarantors. No cash interest will accrue on these notes prior to maturity. The accreted value of these notes will increase at a rate of 11.25 % per annum compounded semiannually on January 15 and July 15 of each year, such that the accreted value will equal the principal amount at maturity. We recognized discount accretion of $ 16,307 and $ 21,440 for the three months ended June 30, 2025 and 2024, respectively, and $ 38,429 and $ 42,099 for the six months ended June 30, 2025 and 2024, respectively, for our senior secured notes due 2026 in interest expense in our condensed consolidated statements of comprehensive income (loss). 12 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) The table below represents our indebtedness repayments, excluding scheduled payments on amortizing debt, for the six months ended June 30, 2025: Date Debt Instrument Secured Property Count Interest Rate Original Maturity Date Outstanding Principal Balance Repayment Amount Remaining Principal Balance Loss on Modification or Early Extinguishment of Debt Repayments during the six months ended June 30, 2025: March 2025 (1) Senior secured notes 73 — % January 2026 $ 940,534 $ 299,158 $ 641,376 $ 29,071 April 2025 Senior unsecured notes — 9.75 % June 2025 $ 380,000 140,000 $ 240,000 82 May 2025 Senior unsecured notes — 9.75 % June 2025 $ 240,000 140,000 $ 100,000 44 June 2025 Senior unsecured notes — 9.75 % June 2025 $ 100,000 100,000 $ — — Total $ 679,158 $ 29,197 (1) During the six months ended June 30, 2025, we sold 22 properties that secured our senior secured notes due 2026.

In March 2025, we executed a $ 140,000 floating rate mortgage loan secured by 14 SHOP communities. This mortgage loan matures in March 2028 and requires that interest be paid at an annual rate of SOFR plus a premium of 2.50 % with interest-only payments through April 2027. In April 2025, we executed a $ 108,873 fixed rate mortgage financing secured by seven SHOP communities.

In June 2025, we obtained a $ 150,000 revolving credit facility secured by 14 senior living communities in our SHOP segment. Our revolving credit facility is available for general business purposes, including acquisitions. We can borrow, repay and reborrow funds available under our revolving credit facility, and no principal repayments are due, until maturity. Availability of borrowings under the agreement governing our revolving credit facility, or our credit agreement, is subject to satisfying certain financial covenants and other credit facility conditions. Our revolving credit facility matures in June 2029 and we have two six-month extension options for the maturity date of the facility, subject to satisfaction of certain conditions and payment of an extension fee. Interest payable on borrowings under our revolving credit facility is based on SOFR plus a premium of 2.50 % to 3.00 %, depending on our net leverage ratio, as defined in our credit agreement, which was 2.50 % as of June 30, 2025. We also pay an unused commitment fee of 25 to 35 basis points per annum based on amounts outstanding under our revolving credit facility. As of June 30, 2025, the annual interest rate payable on borrowings under our revolving credit facility was 7.05 %. As of June 30, 2025 and August 1, 2025, we had no borrowings under our revolving credit facility and $ 150,000 available for borrowings. Interest on our senior unsecured notes is payable either semiannually or quarterly in arrears; however, no principal repayments are due until maturity.

Payments under our finance leases are due monthly. We include amortization of finance lease assets in depreciation and amortization expense. Our credit agreement, our mortgage loan agreements and our senior notes indentures and their supplements provide for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default. Our credit agreement and our senior notes indentures and their supplements also contain covenants that restrict our ability to incur debts, including debts secured by mortgages on our properties, in excess of calculated amounts and require us to maintain various financial ratios. Borrowings under our revolving credit facility are subject to satisfying certain financial covenants and other credit facility conditions. We believe we were in compliance with the terms and conditions of our debt agreements as of June 30, 2025. Note 6. Fair Value of Assets and Liabilities The following table presents certain of our assets that are measured at fair value at June 30, 2025 and December 31, 2024, categorized by the level of inputs as defined in the fair value hierarchy under GAAP, used in the valuation of each asset. As of June 30, 2025 As of December 31, 2024 Description Carrying Value Carrying Value Recurring Fair Value Measurements Assets: Investment in unconsolidated joint venture (Level 3) (1) $ 94,415 $ 81,949 Investment in unconsolidated joint venture (Level 3) (2) $ 44,736 $ 44,910 Interest rate cap (Level 2) (3) $ 18 $ — Non-Recurring Fair Value Measurements Assets: Real estate properties held for sale (Level 2) (4) $ 40,934 $ — (1) The 10 % equity interest we own in the Seaport JV is included in investments in unconsolidated joint ventures in our condensed consolidated balance sheet, and is reported at fair value, which is based on significant unobservable inputs (Level 3 inputs). The significant unobservable inputs used in the fair value analysis are a discount rate of 7.00 %, an exit capitalization rate of 6.00 %, a holding period of 10 years and market rents. The assumptions made in the fair value analysis are based on the location, type and nature of the property, and current and anticipated market conditions. See Note 3 for further information regarding this joint venture. (2) The 20 % equity interest we own in the LSMD JV is included in investments in unconsolidated joint ventures in our condensed consolidated balance sheet, and is reported at fair value, which is based on significant unobservable inputs (Level 3 inputs). The significant unobservable inputs used in the fair value analysis are discount rates of between 6.50 % and 9.50 %, exit capitalization rates of between 5.50 % and 8.50 %, holding periods of 10 years and market rents. The assumptions we made in the fair value analysis are based on the location, type and nature of each property, and current and anticipated market conditions. See Note 3 for further information regarding this joint venture. (3) The fair value of our interest rate cap derivative is based on prevailing market prices in secondary markets for similar derivative contracts as of the measurement date. (4) We have assets in our condensed consolidated balance sheets that are measured at fair value on a non-recurring basis. During the three months ended June 30, 2025, we recorded impairment charges of $ 13,794 to reduce the carrying value of seven medical office properties, two of which are classified as held for sale, to their estimated sales price, less estimated costs to sell, of $ 17,892 under agreements or letters or intent to sell that we have entered into with third parties. During the three months ended June 30, 2025, we also recorded impairment charges of $ 17,199 to reduce the carrying value of 10 senior living communities classified as held for sale to their estimated sales price, less estimated costs to sell, of $ 23,042 under agreements to sell that we have entered into with third parties.

We estimated the fair values of our two issuances of senior unsecured notes due 2042 and 2046 based on the closing price on The Nasdaq Stock Market LLC, or Nasdaq, as of June 30, 2025 and December 31, 2024 (Level 1 inputs as defined in the fair value hierarchy under GAAP). We estimated the fair values of our three issuances of senior unsecured notes due 2025, 2028 and 2031 and our issuance of senior secured notes due 2026 using an average of the bid and ask price on Nasdaq on or about June 30, 2025 and December 31, 2024 (Level 2 inputs as defined in the fair value hierarchy under GAAP). We estimated the fair values of our secured debts by using discounted cash flows analyses and currently prevailing market terms as of the measurement date (Level 3 inputs as defined in the fair value hierarchy under GAAP). Because Level 3 inputs are unobservable, our estimated fair values may differ materially from the actual fair values. Note 7.

Segment Reporting Our operating segments are based on our internal reporting structure and property type and are aligned with how our Chief Operating Decision Maker, or the CODM, reviews the operating results to allocate resources and assess segment performance. The CODM is our President and Chief Executive Officer. Our two reportable segments are SHOP and Medical Office and Life Science Portfolio. Our SHOP segment consists of managed senior living communities that provide short term and long term residential living and, in some instances, care and other services for residents where we pay fees to managers to operate the communities on our behalf. Our Medical Office and Life Science Portfolio segment primarily consists of medical office properties leased to medical providers and other medical related businesses, as well as life science properties primarily leased to biotech laboratories and other similar tenants. The significant expense categories and amounts presented below align with the segment-level information that is regularly provided to our CODM. The CODM reviews operating and financial results, including net income (loss) and its components, to assess performance, allocate resources and guide strategic decisions. For further information regarding the accounting policies of our reportable segments, see Note 2 to our consolidated financial statements included in Part IV, Item 15 of our Annual Report.

In January 2025, in connection with a $ 100,000 credit agreement and related security agreement entered into by RMR and certain of its subsidiaries with Citibank, N.A., or Citibank, and the other lenders party thereto, we consented to the pledge and assignment of RMR’s interest in our management agreements under the security agreement. Pursuant to the consent, we agreed, among other things, that upon notice that an event of default under the RMR credit agreement has occurred and is continuing, we will continue to make all payments under our management agreements in accordance with the instructions of Citibank, and that if there is an event of default by RMR under our management agreements that would allow us to terminate or suspend our obligations, we will not terminate or suspend without notice to Citibank and provide Citibank 30 days to cure the default on RMR’s behalf. The consent was approved by our Independent Trustees. Management Agreements between our Joint Ventures and RMR. We have two separate joint venture arrangements with third party institutional investors, the Seaport JV and the LSMD JV. RMR provides management services to both of these joint ventures.

Derivatives and Hedging Activities We are exposed to certain risks relating to our ongoing business operations, including the impact of changes in interest rates. The only risk currently managed by us using derivative instruments is our interest rate risk. As required under the applicable loan agreement, we have an interest rate cap agreement to manage our interest rate risk exposure on our $ 140,000 floating rate mortgage loan secured by 14 SHOP communities with interest payable at a rate equal to SOFR plus a premium of 2.50 %. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, we only enter into derivative financial instruments with counterparties with high credit ratings and with major financial institutions with which we or our related parties may also have other financial relationships. We do not anticipate that any of the counterparties will fail to meet their obligations. Our interest rate cap agreement is designated as a cash flow hedge of interest rate risk and is measured on a recurring basis at fair value. See Notes 5 and 6 for further information regarding the debt our interest rate cap is related to and the fair value of our interest rate cap. The following table summarizes the terms of our outstanding interest rate cap agreement as of June 30, 2025: Balance Sheet Line Item Underlying Instrument Maturity Date Strike Rate Notional Amount Fair Value Other assets, net Floating rate mortgage loan 3/31/2028 4.50 % $ 140,000 $ 18 Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. For derivatives designated and qualifying as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in cumulative other comprehensive income (loss) and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. Gains and losses on the derivative representing hedge components excluded from the assessment of effectiveness are recognized over the life of the hedge on a systematic and rational basis, as documented at hedge inception in accordance with our accounting policy election. The earnings recognition of excluded components is presented in interest expense. Amounts reported in cumulative other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made, if any, on our applicable debt. The following table summarizes the activity related to our cash flow hedges within cumulative other comprehensive income (loss) for the periods shown: Three Months Ended June 30, 2025 Six Months Ended June 30, 2025 Amount of loss recognized on derivative in other comprehensive income (loss) $ ( 23 ) $ ( 29 ) Amount of loss reclassified from cumulative other comprehensive income (loss) into interest expense $ ( 12 ) $ ( 12 ) Total amount of interest expense presented in the condensed consolidated statements of comprehensive income (loss) $ ( 50,926 ) $ ( 108,757 ) Note 13. Income Taxes We have elected to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, and, as such, are generally not subject to federal and most state income taxation on our operating income provided we distribute our taxable income to our shareholders and meet certain organization and operating requirements. We do, however, lease our managed senior living communities to our wholly owned TRSs that, unlike most of our subsidiaries, file a separate consolidated federal corporate income tax return and are subject to federal and state income taxes. Our consolidated income tax provision includes the income tax provision related to the operations of our TRSs and certain state income taxes we incur despite our taxation as a REIT. Our current income tax expense (or benefit) fluctuates from period to period based primarily on the timing of our income, including gains on the disposition of properties or losses in a particular quarter. For the three months ended June 30, 2025 and 2024, we recognized income tax expense of $ 843 and $ 170 , respectively, and for the six months ended June 30, 2025 and 2024, we recognized income tax expense of $ 892 and $ 357 , respectively. 24 Table of Contents DIVERSIFIED HEALTHCARE TRUST NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (dollar amounts in thousands, except per share data or as otherwise stated) Note 14. Weighted Average Common Share s We calculate basic earnings per common share using the two class method. We calculate diluted earnings per share using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, together with the related impact on earnings, are considered when calculating diluted earnings per share. 25 Table of Contents
