Supplemental Q1 2021 3 The Company: Diversified Healthcare Trust, or DHC, we, our or us, is a real estate investment trust, or REIT, which owns healthcare related properties including medical office and life science buildings, senior living communities and wellness centers located throughout the U.S. DHC is a component of 132 market indices and it comprises more than 1% of the following indices as of March 31, 2021: BI North America Healthcare REIT Valuation Peers (BIHLCRNP) and the Invesco S&P SmallCap Financials ETF INAV Index (PSCFIV). Management: DHC is managed by The RMR Group LLC, or RMR LLC, the majority owned operating subsidiary of The RMR Group Inc. (Nasdaq: RMR). RMR is an alternative asset management company that is focused on commercial real estate and related businesses. RMR primarily provides management services to publicly traded real estate companies, privately held real estate funds and real estate related operating businesses. As of March 31, 2021, RMR had $31.8 billion of real estate assets under management and the combined RMR managed companies had approximately $10 billion of annual revenues, nearly 2,100 properties and approximately 43,000 employees. We believe that being managed by RMR is a competitive advantage for DHC because of RMR’s depth of management and experience in the real estate industry. We also believe RMR provides management services to us at costs that are lower than we would have to pay for similar quality services if we were self managed.

Supplemental Q1 2021 37 Non-GAAP Financial Measures We present certain "non-GAAP financial measures" within the meaning of applicable rules of the SEC, including net operating income, or NOI, Cash Basis NOI, same property NOI, same property Cash Basis NOI, earnings before interest, income tax, depreciation and amortization, or EBITDA, EBITDA for real estate, or EBITDAre, Adjusted EBITDAre, funds from operations attributable to common shareholders, or FFO attributable to common shareholders, and normalized funds from operations attributable to common shareholders, or Normalized FFO attributable to common shareholders. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income (loss) or net income (loss) attributable to common shareholders as indicators of our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income (loss) and net income (loss) attributable to common shareholders as presented in our condensed consolidated statements of income (loss). We consider these non-GAAP measures to be appropriate supplemental measures of operating performance for a REIT, along with net income (loss) and net income (loss) attributable to common shareholders. We believe these measures provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation and amortization, they may facilitate a comparison of our operating performance between periods and with other REITs and, in the case of NOI, Cash Basis NOI, same property NOI and same property Cash Basis NOI, reflecting only those income and expense items that are generated and incurred at the property level may help both investors and management to understand the operations of our properties. NOI, Cash Basis NOI, Same Property NOI and Same Property Cash Basis NOI The calculations of NOI, Cash Basis NOI, same property NOI and same property Cash Basis NOI exclude certain components of net income (loss) in order to provide results that are more closely related to our property level results of operations. We calculate NOI, Cash Basis NOI, same property NOI and same property Cash Basis NOI as shown on pages 16 through 22. We define NOI as income from our real estate less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions that we record as depreciation and amortization. We define Cash Basis NOI as NOI excluding non-cash straight line rent adjustments, lease value amortization, lease termination fee amortization, if any, and non-cash amortization included in property operating expenses. We calculate same property NOI and same property Cash Basis NOI in the same manner that we calculate the corresponding NOI and Cash Basis NOI amounts, except that we only include same properties in calculating same property NOI and same property Cash Basis NOI. We use NOI, Cash Basis NOI, same property NOI and same property Cash Basis NOI to evaluate individual and company wide property level performance. Other real estate companies and REITs may calculate NOI, Cash Basis NOI, same property NOI and same property Cash Basis NOI differently than we do. EBITDA, EBITDAre and Adjusted EBITDAre We calculate EBITDA, EBITDAre and Adjusted EBITDAre as shown on page 23. EBITDAre is calculated on the basis defined by the National Association of Real Estate Investment Trusts, or Nareit, which is EBITDA, excluding gains or losses on the sale of properties, impairment of assets, if any, including adjustments to reflect our proportionate share of EBITDAre of our equity method investment in Five Star, as well as certain other adjustments currently not applicable to us. In calculating Adjusted EBITDAre, we adjust for the items shown on page 23. Other real estate companies and REITs may calculate EBITDA, EBITDAre and Adjusted EBITDAre differently than we do. FFO and Normalized FFO Attributable to Common Shareholders We calculate FFO attributable to common shareholders and Normalized FFO attributable to common shareholders as shown on page 24. FFO attributable to common shareholders is calculated on the basis defined by Nareit, which is net income (loss) attributable to common shareholders, calculated in accordance with GAAP, excluding any gain or loss on sale of properties, loss on impairment of real estate assets and gains or losses on equity securities, net, if any, including adjustments to reflect our proportionate share of FFO of our equity method investment in Five Star, plus real estate depreciation and amortization and minus FFO adjustments attributable to noncontrolling interest, as well as certain other adjustments currently not applicable to us. In calculating Normalized FFO attributable to common shareholders, we adjust for the items shown on page 24. FFO attributable to common shareholders and Normalized FFO attributable to common shareholders are among the factors considered by our Board of Trustees when determining the amount of distributions to our shareholders. Other factors include, but are not limited to, requirements to maintain our qualification for taxation as a REIT, limitations in the agreements governing our debt, the availability to us of debt and equity capital, our expectation of our future capital requirements and operating performance, and our expected needs for and availability of cash to pay our obligations. Other real estate companies and REITs may calculate FFO attributable to common shareholders and Normalized FFO attributable to common shareholders differently than we do. Non-GAAP Financial Measures and Certain Definitions RETURN TO TABLE OF CONTENTS

Supplemental Q1 2021 38 Adjusted total assets Adjusted total assets is the original cost of real estate assets calculated in accordance with GAAP before depreciation and after impairment write downs, if any, and excludes accounts receivable and intangible assets. Annualized dividend yield Annualized dividend yield is the annualized dividend declared during the applicable period divided by the closing price of DHC's common shares on The Nasdaq Stock Market LLC at the end of the relevant period. Annualized rental income Annualized rental income is based on rents pursuant to existing leases as of March 31, 2021. Annualized rental income includes estimated percentage rents, straight line rent adjustments and estimated recurring expense reimbursements for certain net and modified gross leases; excludes lease value amortization at certain of our medical office and life science properties and wellness centers. Annualized rental income amounts for our medical office and life science properties also include 100% of rental income as reported under GAAP from the life science property owned in a joint venture arrangement in which we own a 55% equity interest. Average monthly rate Average monthly rate is calculated by taking the average daily rate, which is defined as total residents fees and services divided by occupied units during the period, and multiplying it by 30 days. Building improvements Building improvements generally include expenditures to replace obsolete building components that extend the useful life of existing assets or other improvements to increase the marketability of the property. Cash basis NOI margin % Cash basis NOI margin % is defined as cash basis NOI as a percentage of cash basis rental income. Cash basis rental income excludes non-cash straight line rent adjustments, lease value amortization and lease termination fee amortization, if any. Consolidated income available for debt service Consolidated income available for debt service is earnings from operations excluding interest expense, depreciation and amortization, taxes, loss on asset impairment, gains or losses on equity securities, gains or losses on sales of properties and early extinguishment of debt, determined together with debt service for the applicable period. Development, redevelopment and other activities Development, redevelopment and other activities generally include capital expenditures that reposition a property or result in new sources of revenue. From time to time we invest in revenue producing capital improvements at certain of our triple net leased senior living communities. As a result, annual rents payable to us increase pursuant to the terms of the applicable leases. These capital improvements are not included in our development, redevelopment and other activities. Estimated completion date Estimated completion date can depend on various factors, including when lease agreements are signed with tenants. Therefore, the actual completion date may vary.
