Among this list, DHC comprises more than 1% of Newton, MA 02458-1634 indices such as: Bloomberg Real Estate Investment Trust Healthcare Index (BBREHLTH), Fidelity Canada (t) (617) 796-8350 U.S. High Dividend Index PR (FIDCNHDP), BI North America Healthcare REIT Valuation Peers (BIHLCRNP), BI NA Healthcare REIT – Competitive (BIHLCRNC), Invesco KBW Premium Yield Equity REIT ETF INAV COMPANY PROFILE COMPANY Index (KBWYIV), Indxx Old Age REITs Index (IOLDAGE), Indxx Old Age REITs Index PR (IOLDAGEP), Indxx Old Age REITs Index TR (IOLDAGET), Solactive Long Term Care Index (OLDID), and the Solactive US Small Cap High Dividend Index (SOLSMHD). 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 Senior Unsecured Debt Ratings: 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 Moody's: Ba1 also advises the RMR Real Estate Income Fund, a publicly traded closed end fund that invests in publicly S&P Global: BBB- traded securities of real estate companies, and Tremont Mortgage Trust, a publicly traded mortgage REIT that focuses 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 well as manages the RMR Office Property Fund LP, a private, open end core plus fund focused on the acquisition, ownership and leasing of a diverse portfolio of multi- tenant office properties throughout the U.S. As of December 31, 2019, RMR had $32.2 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 50,000 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 SEC rules, 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, 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 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 at 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 19 through 23. 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 24. 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 24 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 month periods and years ended December 31, 2019 and 2018. 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 (rent and management fees) between us and Five Star during the periods presented. The table on page 38 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 25. 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 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 25 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 NON-GAAP FINANCIAL MEASURES AND CERTAIN DEFINITIONS AND CERTAIN MEASURES FINANCIAL NON-GAAP 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 our revolving credit facility and term loan agreements and our public debt covenants, 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. 41
