COMPANY PROFILE The Company: Corporate Headquarters: 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 Two Newton Place wellness centers located throughout the U.S. DHC is a component of 67 market indices and it comprises 255 Washington Street, Suite 300 more than 1% of the following indices as of June 30, 2020: BI North America Healthcare REIT Valuation Newton, MA 02458-1634 Peers (BIHLCRNP), Invesco KBW Premium Yield Equity REIT ETF INAV Index (KBWYIV), BI NA Healthcare (t) (617) 796-8350 REIT – Competitive (BIHLCRNC), Solactive Long Term Care Index (OLDID), and the Bloomberg Real Estate Investment Trust Healthcare Index (BBREHLTH). COMPANY PROFILE COMPANY Management: Stock Exchange Listing: DHC is managed by The RMR Group LLC, or RMR LLC, the majority owned operating subsidiary of The RMR Group Inc. (Nasdaq: RMR), or RMR Inc. RMR is an alternative asset management company that was Nasdaq founded in 1986 to manage real estate companies and related businesses. RMR primarily provides management services to four publicly traded equity REITs and three real estate related operating businesses. Trading Symbols: In addition to managing DHC, RMR manages Service Properties Trust, a REIT that owns a diverse portfolio of hotels and net lease service and necessity-based retail properties, Industrial Logistics Properties Trust, a Common Shares: DHC REIT that owns industrial and logistics properties, and Office Properties Income Trust, a REIT that owns 5.625% Senior Notes due 2042: DHCNI properties primarily leased to single tenants and those with high credit quality characteristics such as 6.250% Senior Notes due 2046: DHCNL government entities. RMR also provides management services to Five Star Senior Living Inc., or Five Star, a publicly traded operator of senior living communities (including many of the senior living communities that DHC owns), Sonesta International Hotels Corporation, a privately owned operator and franchisor of hotels and cruise boats, and TravelCenters of America Inc., a publicly traded operator and franchisor of travel centers along the U.S. Interstate Highway System, standalone truck service facilities and restaurants. RMR also advises RMR Mortgage Trust (formerly known as RMR Real Estate Income Fund), which is in the process of converting from a registered investment company to a publicly traded mortgage REIT, and Tremont Mortgage Trust, a publicly traded mortgage REIT, both of which will focus on originating and investing in floating rate first mortgage whole loans, secured by middle market and transitional commercial real estate, through wholly owned Securities and Exchange Commission, or SEC, registered investment advisory subsidiaries. As of June 30, 2020, RMR had $32.0 billion of real estate assets under management and the combined RMR managed companies had approximately $12 billion of annual revenues, over 2,100 properties and nearly 45,000 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. 4

NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS 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 18 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, Adjusted EBITDAre and EBITDARM 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 and losses on the sale of real estate, loss on impairment of real estate assets, if any, as well as certain other adjustments currently not applicable to us. In calculating Adjusted EBITDAre, we adjust for the items shown on page 23 and include business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. Other real estate companies and REITs may calculate EBITDA, EBITDAre and Adjusted EBITDAre differently than we do. Our SHOP segment includes both communities leased to Five Star and operated for our account under management agreements with Five Star as of and during the three and six months ended June 30, 2019. Pursuant to the Restructuring Transaction, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with the New Management Agreements as of January 1, 2020. Under the New Management Agreements, management fees are 5% of resident fees and services revenues. We believe pro forma earnings before interest, taxes, depreciation, amortization, rent and management fees, or EBITDARM, is a meaningful transitional supplemental performance measure as it presents historical community level operating results regardless of the form of contractual arrangements and removes the impact of changes in the agreements (rents and management fees) between us and Five Star during the periods presented. The table on page 37 presents pro forma resident fees and services and pro forma EBITDARM as if the communities had been managed for our account throughout all periods presented to assist in understanding community level operating results. Other real estate companies and REITs may calculate EBITDARM 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, 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 and include business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as an expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS AND CERTAIN MEASURES FINANCIAL NON-GAAP performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. 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. 40

NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS (CONTINUED) 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. (CONTINUED) Annualized rental income Annualized rental income is based on rents pursuant to existing leases as of June 30, 2020. 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 our 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. GAAP GAAP is U.S. generally accepted accounting principles. Gross book value of real estate assets Gross book value of real estate assets is real estate assets at cost plus certain acquisition costs, before depreciation and purchase price allocations, less impairment writedowns, if any. Gross purchase price Gross purchase price includes assumed debt, if any, and excludes acquisition costs and purchase price allocation adjustments, if any. Gross sales price Gross sales price excludes closing costs. Lease related costs Lease related costs generally include capital expenditures to improve tenants’ space or amounts paid directly to tenants to improve their space NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS AND CERTAIN MEASURES FINANCIAL NON-GAAP and leasing related costs, such as brokerage commissions and tenant inducements. Net debt Net debt is total debt less cash. 41

NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS (CONTINUED) NOI margin % NOI margin % is defined as NOI as a percentage of rental income. Non-Segment Non-Segment operations consists of triple net leased senior living communities that are leased to third party operators other than Five Star and wellness centers, and any other income or expenses that are not attributable to a specific reporting segment. (CONTINUED) Office Portfolio Office Portfolio consists of medical office properties leased to medical providers and other medical related businesses, as well as life science properties leased to biotech laboratories and other similar tenants. Rent coverage Rent coverage is calculated as operating cash flows from our tenants' facility operations of our properties, before subordinated charges, if any, divided by rent payable to us. Same Property For the three months ended June 30, 2020, same property consists of properties owned, in service and operated by the same operator continuously since April 1, 2019, including our life science property owned in a joint venture arrangement in which we own a 55% equity interest; excludes properties classified as held for sale or out of service undergoing redevelopment, if any. For the six months ended June 30, 2020, same property consists of properties owned, in service and operated by the same operator continuously since January 1, 2019, including our life science property owned in a joint venture arrangement in which we own a 55% equity interest; excludes properties classified as held for sale or out of service undergoing redevelopment, if any. SHOP SHOP, or Senior Housing Operating Portfolio, consists of managed senior living communities that provide short term and long term residential living and in some cases care and other services for residents where we pay fees to the operator to manage the communities for our account. Properties in this segment include independent living communities, assisted living communities, active adult rental communities and SNFs. Pursuant to the Restructuring Transaction, the previously existing master leases and management and pooling agreements between us and Five Star were terminated and replaced with the New Management Agreements as of January 1, 2020. Prior to January 1, 2020, these senior living communities were either managed for our account by Five Star or triple net leased to Five Star. SNF SNF is a skilled nursing facility. Total gross assets Total gross assets is total assets plus accumulated depreciation. Total unencumbered assets Total unencumbered assets is the original cost of real estate assets not encumbered by mortgage debt calculated in accordance with GAAP before depreciation and after impairment write downs, if any, and exclude accounts receivable and intangible assets.
