SENIOR HOUSING PROPERTIES TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

Note 1. Basis of Presentation

The accompanying condensed consolidated financial statements of Senior Housing Properties Trust and its subsidiaries, or 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, 2013, or our Annual Report. In the opinion of our management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation 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. Reclassifications have been made to the prior year’s financial statements to conform to the current year’s presentation. These reclassifications were made to conform the prior periods’ rental income, property operating expenses, discontinued operations, general and administrative expenses, interest and other income and impairment of assets to the current classification. These reclassifications had no effect on net income or shareholders’ equity.

Note 2. Recent Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This update amends the criteria for reporting discontinued operations to, among other things, change the criteria for disposals to qualify as discontinued operations. This update is effective for interim and annual reporting periods, beginning after December 15, 2014, with early adoption permitted. We currently expect the adoption of this update to reduce the number of future property dispositions we make, if any, to be presented as discontinued operations in our condensed consolidated financial statements.

Note 3. Real Estate Properties

At March 31, 2014, we owned 374 properties (400 buildings) located in 40 states and Washington, D.C. We have accounted, or expect to account for the following acquisitions as business combinations unless otherwise noted.

MOB Acquisitions:

In April 2014, we acquired one property (one building) leased to medical providers, medical related businesses, clinics and biotech laboratory tenants, or an MOB, for approximately $32,658, including the assumption of approximately $15,630 of mortgage debt, and excluding closing costs. This MOB is located in Texas and includes 125,240 square feet of leasable space. We funded this acquisition using cash on hand and borrowings under our revolving credit facility.

In February 2014, we entered into an agreement to acquire one MOB (two buildings) for approximately $1,125,420, excluding closing costs. This MOB is located in Massachusetts and includes 1,651,037 gross building square feet. The closing of this acquisition is contingent upon various closing conditions; accordingly, we can provide no assurance that we will purchase this property, that this acquisition will not be delayed or that its terms will not change.

(dollar amounts in thousands, except per share data or as otherwise stated)

Impairment

We periodically evaluate our properties for impairments. Impairment indicators may include declining tenant occupancy, weak or declining tenant profitability, 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 indicators of impairment are present, we evaluate the carrying value of the affected property by comparing it to the expected future undiscounted net cash flows to be generated from that property. If the sum of these expected future net cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value. During the three months ended March 31, 2013, we recorded an impairment of assets charge of $1,304 to reduce the carrying value of one of our properties held for use to its estimated net sale price.

As of March 31, 2014, we had nine senior living communities with 708 units and four MOBs (seven buildings) with 831,499 square feet categorized as properties held for sale. During the three months ended March 31, 2014, we recorded impairment of assets charges of $721 to reduce the carrying value of two MOBs included in discontinued operations to their aggregate estimated net sale price. The 13 properties are included in other assets in our condensed consolidated balance sheets and have a net book value (after impairment) of approximately $25,644 at March 31, 2014. As of December 31, 2013, we had 10 senior living communities with 744 units and four MOBs (seven buildings) with 831,499 square feet categorized as properties held for sale, which were similarly recorded and categorized at March 31, 2014, except that one of the senior living communities was sold in January 2014, as noted below. These properties are included in other assets in our condensed consolidated balance sheets and had a net book value (after impairment) of approximately $27,888 at December 31, 2013. We decided to sell these properties due to underlying conditions in the markets where these properties are located. We classify all properties that meet the criteria outlined in the Property, Plant and Equipment Topic of the FASB Accounting Standards Codification, or the Codification, as held for sale in our condensed consolidated balance sheets.

Results of operations for properties sold or held for sale are included in discontinued operations in our condensed consolidated statements of operations once the criteria for discontinued operations in the Presentation of Financial Statements Topic of the Codification are met. Summarized income statement information for the four MOBs (seven buildings) that meet the criteria for discontinued operations is included in discontinued operations as follows:

|  | Three Months Ended March 31, |
|  | 2014 |  | 2013 |
Rental income |  | $ | 2,294 |  | $ | 2,521 |
Property operating expenses |  | (994 | ) | (903 | )
Depreciation and amortization |  | — |  | (599 | )
Income from discontinued operations |  | $ | 1,300 |  | $ | 1,019 |

In January 2014, we sold a senior living community with 36 units that was previously classified as held for sale for $2,400 and recorded a gain on the sale of this property of approximately $156.

In April 2014, we sold one MOB (one building) for approximately $5,000, excluding closing costs. We will record the gain or loss on this sale during the period ended June 30, 2014 when all of the costs of the sale are known.

SENIOR HOUSING PROPERTIES TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

The senior living properties which we are offering for sale do not meet the criteria for discontinued operations as they are included within combination leases with other properties that we expect to continue leasing.

Note 4. Unrealized Gain / Loss on Investments

As of March 31, 2014, we owned 250,000 common shares of CommonWealth REIT, or CWH, and 4,235,000 common shares of Five Star Quality Care, Inc., or Five Star, which are carried at fair market value in other assets on our condensed consolidated balance sheets. Cumulative other comprehensive income shown in our condensed consolidated balance sheets includes the net unrealized gain or loss on investments determined as the net difference between the value at quoted market prices of our CWH and Five Star shares as of March 31, 2014 ($26.30 and $4.86 per share, respectively) and our weighted average costs at the time we acquired these shares, as adjusted to reflect any share splits or combinations ($26.00 and $3.36 per share, respectively).

Note 5. Indebtedness

Our principal debt obligations at March 31, 2014 were: (1) outstanding borrowings under our $750,000 unsecured revolving credit facility; (2) four public issuances of unsecured senior notes, including: (a) $250,000 principal amount at an annual interest rate of 4.30% due 2016, (b) $200,000 principal amount at an annual interest rate of 6.75% due 2020, (c) $300,000 principal amount at an annual interest rate of 6.75% due 2021 and (d) $350,000 principal amount at an annual interest rate of 5.625% due 2042; and (3) $678,514 aggregate principal amount of mortgages secured by 48 of our properties (51 buildings) with maturity dates from 2014 to 2043. The 48 mortgaged properties (51 buildings) had a carrying value of $941,064 at March 31, 2014. We also had two properties subject to capital leases totaling $13,181 at March 31, 2014; these two properties had a carrying value of $18,534 at March 31, 2014.

In September 2013, we amended the agreement governing our unsecured revolving credit facility with Wells Fargo Bank, National Association, as administrative agent, and a syndicate of other lenders. As a result of the amendment the stated maturity date of the revolving credit facility was extended from June 24, 2015 to January 15, 2018. Subject to the payment of an extension fee and meeting certain other conditions, we have an option to further extend the stated maturity date by an additional one year. The revolving credit facility agreement provides that we can borrow, repay and reborrow funds available under the revolving credit facility agreement until maturity, and no principal repayment is due until maturity. The $750,000 maximum amount of our revolving credit facility remained unchanged by the amendment. The revolving credit facility agreement continues to include a feature under which maximum borrowings under the facility may be increased to up to $1,500,000 in certain circumstances. Under this amendment, the interest rate paid on borrowings under the revolving credit facility agreement is LIBOR plus a premium of 130 basis points, and the facility fee is 30 basis points per annum on the total amount of lending commitments. Both the interest rate premium and the facility fee are subject to adjustment based upon changes to our credit ratings. The weighted average interest rate for borrowings under our revolving credit facility was 1.42% for the three months ended March 31, 2014. We incurred interest expense and other associated costs related to our revolving credit facility of $425 for the three months ended March 31, 2014. As of March 31, 2014 and May 2, 2014, we had $145,000 and $0 outstanding and $605,000 and $750,000 available under our revolving credit facility, respectively.

Our revolving credit facility agreement provides for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, such as a change of control of us, which

SENIOR HOUSING PROPERTIES TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(dollar amounts in thousands, except per share data or as otherwise stated)

includes Reit Management & Research LLC, or RMR, ceasing to act as our business manager and property manager.

Our public debt indentures and related supplements and our credit facility agreement contain a number of financial and other covenants, including covenants that restrict our ability to incur indebtedness or to make distributions under certain circumstances and require us to maintain financial ratios and a minimum net worth.

In April 2014, we sold $400,000 of 3.25% senior unsecured notes due 2019 and $250,000 of 4.75% senior unsecured notes due 2024, raising net proceeds of approximately $644,889, after underwriting discounts but before expenses. We plan to use the net proceeds of this offering for general business purposes, including funding the pending acquisition described in Note 3.

Note 6. Shareholders’ Equity

On February 21, 2014, we paid a $0.39 per share, or $73,386, distribution to our common shareholders with respect to our operating results for the quarter ended December 31, 2013. On April 2, 2014, we declared a quarterly distribution of $0.39 per share, or $73,393, to our common shareholders of record on April 14, 2014, with respect to our operating results for the quarter ended March 31, 2014; we expect to pay this distribution on or about May 21, 2014.

We issued 19,937 common shares to RMR during the three months ended March 31, 2014 and 10,342 shares in April 2014, as part of its compensation under our business management agreement. See Note 10 for further information regarding this agreement.

In April 2014, we issued 15,525,000 common shares in a public offering, raising net proceeds of approximately $323,318, after underwriting discounts but before expenses. We used the net proceeds from this offering to repay borrowings outstanding under our revolving credit facility and for general business purposes, including the partial funding of the pending acquisition described in Note 3.

Note 7. Fair Value of Assets and Liabilities

The following table presents certain of our assets and liabilities that are measured at fair value on a recurring and non recurring basis at March 31, 2014 categorized by the level of inputs used in the valuation of each asset or liability.

(dollar amounts in thousands, except per share data or as otherwise stated)

(1) Assets held for sale consist of thirteen of our properties that we expect to sell that are reported at fair value less costs to sell. We used offers to purchase these properties made by third parties or comparable sales transactions (Level 2 inputs) to determine the fair value of these properties. We have recorded cumulative impairments of approximately $41,911 to these properties in order to reduce their book value to fair value.

(2) Long-lived assets held and used consist of one of our properties for which we reduced the carrying value. We used broker information and comparable sales transactions (Level 2 inputs) to determine the fair value of this property. We previously recorded an impairment of assets charge of $1,304 for the three months ended March 31, 2013 for this property in order to reduce its carrying value to the amount stated.

(3) Our investments in available for sale securities include our 250,000 common shares of CWH and 4,235,000 common shares of Five Star. The fair values of these shares are based on quoted prices at March 31, 2014 in active markets (Level 1 inputs).

(4) We estimate the fair values of our unsecured senior notes using an average of the bid and ask price of our outstanding four issuances of senior notes (Level 1 inputs) on or about March 31, 2014. The fair values of these senior note obligations exceed their aggregate book values of $1,093,658 by $36,685 because these notes were trading at a premium to their face amounts.

(5) We estimate the fair values of our secured debt by using discounted cash flow analyses and currently prevailing market terms at March 31, 2014 (Level 3 inputs). Because Level 3 inputs are unobservable, our estimated fair value may differ materially from the actual fair value.

In addition to the assets and liabilities described in the above table, our additional financial instruments include rents receivable, cash and cash equivalents, restricted cash, other unsecured debt and other liabilities. The fair values of these additional financial instruments approximate their carrying values at March 31, 2014 based upon their liquidity, short term maturity, variable rate pricing or our estimate of fair value using discounted cash flow analyses and prevailing interest rates.

Note 8. Segment Reporting

We have four operating segments, of which three are separately reportable operating segments: (i) triple net senior living communities that provide short term and long term residential care and dining services for residents, (ii) managed senior living communities that provide short term and long term residential care and dining services for residents and (iii) MOBs. Our triple net and managed senior living communities include independent living communities and assisted living communities and skilled nursing facilities, or SNFs. Properties in the MOB segment include medical office, clinic and biotech laboratory buildings. The “All Other” category in the following table includes amounts related to corporate business activities and the operating results of certain properties that offer fitness, wellness and spa services to members.

Subject to the information in the following paragraph, financial information about Five Star may be found on the website of the Securities and Exchange Commission, or SEC, by entering Five Star’s name at http://www.sec.gov/edgar/searchedgar/companysearch.html. Reference to Five Star’s financial information on this external website is presented to comply with applicable accounting guidance of the SEC. Except for such financial information contained therein as is included herein under such guidance, Five Star’s public filings and other information located in external websites are not incorporated by reference into these financial statements.

In April 2014, Five Star filed with the SEC an amended Annual Report on Form 10-K for the year ended December 31, 2012 and amended Quarterly Reports on Form 10-Q for the quarters ended March 31, 2013 and June 30, 2013 that restated its financial results for 2011, 2012 and the first and second quarters of 2013 to correct certain errors in the accounting for income taxes and other errors contained in its previously filed financial reports for those periods. In addition, in April 2014, Five Star filed with the SEC its Quarterly Report on Form 10-Q for the quarter ended September 30, 2013. In those filings, Five Star disclosed that, as a result of the matters discussed above, Five Star has material weaknesses in its internal control over financial reporting, that Five Star is currently in the process of developing a remediation plan for the material weaknesses, and that Five Star expects the remediation of the material weaknesses to be completed before December 31, 2014. Five Star has not yet filed its Annual Report on Form 10-K for the year ended December 31, 2013. Five Star has publicly disclosed that it is in the process of preparing its Annual Report on Form 10-K for the year ended December 31, 2013. However, there is no assurance as to when that report will be completed and filed with the SEC.

See Note 10 for further information relating to our leases and management arrangements with Five Star.

Note 10. Related Person Transactions

Five Star: Five Star was formerly our 100% owned subsidiary. Five Star is our largest tenant, we are Five Star’s largest stockholder and Five Star manages several senior living communities for us. In 2001, we distributed substantially all of Five Star’s then outstanding shares of common stock to our shareholders. As of March 31, 2014, we owned 4,235,000 shares of common stock of Five Star, or approximately 8.7% of Five Star’s outstanding shares of common stock. One of our Managing Trustees, Mr. Barry Portnoy, is a managing director of Five Star. RMR provides management services to both us and Five Star. Five Star’s President and Chief Executive Officer and its Chief Financial Officer and Treasurer are officers of RMR.

As of March 31, 2014, we leased 186 senior living communities to Five Star. Under Five Star’s leases with us, Five Star pays us rent consisting of minimum annual rent amounts plus percentage rent based on increases in gross revenues at certain properties. Five Star’s total minimum annual rent payable to us as of March 31, 2014 was $190,614, excluding percentage rent. We recognized total rental income from Five Star of $47,506 and $49,444 for the three months ended March 31, 2014 and 2013, respectively. As of March 31, 2014 and 2013, our rents receivable from Five Star were $15,835 and $17,620, respectively, and those amounts are included in other assets in our condensed consolidated balance sheets. We had deferred estimated percentage rent under our Five Star leases of $1,416 and $1,254 for the three months ended March 31, 2014 and 2013, respectively. We determine percentage rent due under our Five Star leases annually and recognize it at year end when all contingencies are met. During the three months ended March 31, 2014 and 2013, pursuant to the terms of our leases with Five Star, we purchased $8,614 and $8,171, respectively, of improvements made to properties leased to Five Star, and, as a result, the annual rent payable to us by Five Star increased by approximately $689 and $654, respectively.

(dollar amounts in thousands, except per share data or as otherwise stated)

In June 2013, we and Five Star agreed to offer for sale 11 senior living communities we lease to Five Star. Five Star’s rent payable to us will be reduced if and as these sales may occur pursuant to terms set in our leases with Five Star. In August 2013, we sold one of these communities, a SNF, with 112 living units, for a sales price of $2,550, and as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $255, or 10% of the net proceeds of the sale to us, in accordance with the terms of the applicable lease. In January 2014, we sold one senior living community located in Texas with 36 assisted living units, for a sale price of $2,400, and as a result of this sale, Five Star’s annual minimum rent payable to us decreased by $210, or 8.75% of the net proceeds of the sale to us, in accordance with the terms of the applicable lease. We can provide no assurance that the remaining nine senior living communities which we and Five Star have agreed to offer for sale will be sold, when any sales may occur or what the terms of any sales may provide.

Five Star began managing communities for our account in 2011 in connection with our acquisition of certain senior living communities at that time. We have since acquired additional communities that are being managed by Five Star. As of March 31, 2014, Five Star managed 44 senior living communities for our account. We lease our senior living communities that are managed by Five Star that include assisted living units or SNFs to our TRSs, and Five Star manages these communities pursuant to long term management agreements.

In connection with the management agreements, we and Five Star have entered into four combination agreements, or pooling agreements: three pooling agreements combine our management agreements for communities that include assisted living units, or the AL Pooling Agreements, and a fourth pooling agreement, combines our management agreements for communities consisting only of independent living units, or the IL Pooling Agreement. The management agreements that are included in each of our pooling agreements are on substantially similar terms. Each of our first and second AL Pooling Agreements includes 20 identified communities. The third AL Pooling Agreement currently includes the management agreement for a community we acquired in November 2013. The IL Pooling Agreement currently includes management agreements for two communities that have only independent living units. The senior living community in New York described below that Five Star manages for our account is not included in any of our pooling agreements. Each of the AL Pooling Agreements and the IL Pooling Agreement aggregates the determination of fees and expenses of the various communities that are subject to such pooling agreement, including determinations of our return on our invested capital and Five Star’s incentive fees. We incurred management fees of $2,425 and $2,295 for the three months ended March 31, 2014 and 2013, respectively, with respect to the communities Five Star manages. These amounts are included in property operating expenses in our condensed consolidated statements of income and comprehensive income.

We own a senior living community in New York with 310 living units, a portion of which is managed by Five Star pursuant to a long term management agreement with us with respect to the living units at this community that are not subject to the requirements of New York healthcare licensing laws. In order to accommodate certain requirements of New York healthcare licensing laws, one of our TRSs subleases the portion of this community that is subject to those requirements to an entity, D&R Yonkers LLC, which is owned by our President and Chief Operating Officer and Treasurer and Chief Financial Officer. Five Star manages this portion of the community pursuant to a long term management agreement with D&R Yonkers LLC. Under the sublease agreement, D&R Yonkers LLC is obligated to pay rent only from available revenues generated by the subleased community. Our TRS is obligated to advance any rent shortfalls to D&R Yonkers LLC, and D&R Yonkers LLC is obligated to repay one of our TRSs only from available revenues generated by the subleased community.

We may enter into additional management arrangements with Five Star for our senior living communities and we may add the management agreements to our existing pooling agreements or enter into additional pooling agreements with Five Star.

RMR: We have no employees. Personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management and administrative services to us: (i) a business management agreement, which relates to our business generally, and (ii) a property management agreement, which relates to the property level operations of our MOBs.

One of our Managing Trustees, Mr. Barry Portnoy, is Chairman, majority owner and an employee of RMR. Our other Managing Trustee, Mr. Adam Portnoy, is the son of Mr. Barry Portnoy, and an owner, President, Chief Executive Officer and a director of RMR. Each of our executive officers is also an officer of RMR, and our President and Chief Operating Officer, Mr. David Hegarty, is a director of RMR. A majority of our Independent Trustees also serve as independent directors or independent trustees of other public companies to which RMR provides management services. Mr. Barry Portnoy serves as a managing director or managing trustee of a majority of those companies and Mr. Adam Portnoy serves as a managing trustee of a majority of those companies. In addition, officers of RMR serve as officers of those companies.

Pursuant to our business management agreement with RMR, we recognized business management fees of $6,682 and $6,550 for the three months ended March 31, 2014 and 2013, respectively. These amounts are included in general and administrative expenses in our condensed consolidated financial statements. In accordance with the terms of our business management agreement, as amended in December 2013, we issued 30,279 of our common shares to RMR for the three months ended March 31, 2014 as payment for 10% of the base business management fee we recognized for such period.

In connection with our property management agreement with RMR, the aggregate property management and construction supervision fees we recognized were $1,638 and $1,600 for the three months ended March 31, 2014 and 2013, respectively. These amounts are included in property operating expenses or have been capitalized, as appropriate, in our condensed consolidated financial statements.

AIC: We, RMR, Five Star, CWH and four other companies to which RMR provides management services each currently own approximately 12.5% of Affiliates Insurance Company, or AIC, an Indiana insurance company. All of our Trustees and most of the trustees and directors of the other AIC shareholders currently serve on the board of directors of AIC. RMR provides management and administrative services to AIC pursuant to a management and administrative services agreement with AIC.

We and the other shareholders of AIC have purchased property insurance providing $500,000 of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. This program currently expires in June 2014, and we may determine to renew our participation in this program at that time. As of March 31, 2014, we have invested $5,209 in AIC since its formation in 2008. Although we own less than 20% of AIC, we use the equity method to account for this investment because we believe that we have significant influence over AIC as all of our Trustees are also directors of AIC. Our investment in AIC had a carrying value of $5,835 and $5,913 as of March 31, 2014 and December 31, 2013, respectively, which amounts are included in other assets on our condensed consolidated balance sheet. We recognized a loss of $97 and income of $76 related to our investment in AIC for the three months ended March 31, 2014 and 2013, respectively.

On March 25, 2014, as a result of the removal, without cause, of all of the trustees of CWH, CWH underwent a change in control, as defined in the shareholders agreement among us, the other shareholders of AIC and AIC. In April 2014, as a result of the change in control of CWH and in accordance with the terms of the shareholders agreement, we provided notice of exercise of our right to purchase shares of AIC CWH then owned. We expect that we and the other non-CWH shareholders will purchase pro rata all of the AIC shares CWH owns. As such, we expect to purchase 2,857 of those shares for $825, and that following these purchases, we and the other remaining six shareholders will then each own approximately 14.3% of AIC.

Note 11. 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 certain 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 REIT status. During the three months ended March 31, 2014 and 2013, we recognized income tax expense of $191 and $140, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with our condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q and our Annual Report. We are a REIT organized under Maryland law. At March 31, 2014, we owned 374 properties (400 buildings) located in 40 states and Washington, D.C., including 13 properties (16 buildings) classified as held for sale. On that date, the undepreciated carrying value of our properties, net of impairment losses, was $5.3 billion, excluding properties classified as held for sale. As of March 31, 2014, 96% of our net operating income, or NOI, came from properties where a majority of the charges are paid from private resources.

(1) Excludes properties classified in discontinued operations.

(2) Amounts are before depreciation, but after impairment write downs, if any. Amounts include carrying values as of March 31, 2014 for senior living communities classified as held for sale in the amount of $9,495, which is included in Other Assets on the Condensed Consolidated Balance Sheets.

(3) Represents investment carrying value divided by the number of living units, beds or leased square feet at March 31, 2014.

(4) Net operating income, or NOI, is defined and calculated by reportable segment and reconciled to net income below in this Item 2.

(5) Senior living properties are categorized by the type of living units or beds which constitute a the largest number of the living units or beds at the property.

(6) Marriott International, Inc. guarantees the lessee’s obligations under these leases.

(7) These 44 managed senior living communities are managed by Five Star. The occupancy for the twelve month period ended, or, if shorter, from the date of acquisitions through March 31, 2014 was 87.8%.

(8) Operating data for multi-tenant MOBs are presented as of March 31, 2014 and 2013; operating data for other properties, tenants and managers are presented based upon the operating results provided by our tenants and managers for the 12 months ended December 31, 2013 and 2012, or the most recent prior period for which tenant operating results are available to us. Rent coverage is calculated as operating cash flow from our tenants’ operations of our properties, before subordinated charges, if any, divided by rents payable to us. We have not independently verified our tenants’ operating data. The table excludes data for periods prior to our ownership of some of these properties.

(9) Five Star has not filed its Annual Report on Form 10-K for the year ended December 31, 2013, or the Five Star 2013 Form 10-K, with the SEC due to certain errors identified by Five Star’s management in connection with the preparation of its SEC periodic reports for prior periods. Because we do not yet know what impact these errors will have on Five Star’s results to be reported in the Five Star 2013 Form 10-K, we do not report rent coverage for the 12 months ended December 31, 2013 for this tenant or the portfolio as a whole.

Average remaining lease term for all senior living community, MOB and wellness center properties (weighted by annualized rental income): 7.9 years

(1) Annualized rental income is rents pursuant to existing leases as of March 31, 2014, including estimated percentage rents, straight line rent adjustments, estimated recurring expense reimbursements for certain net and modified gross leases and excluding lease value amortization at certain of our MOBs and wellness centers. Excludes properties classified in discontinued operations.

(2) Excludes rent received from our managed senior living communities leased to our TRSs. If the NOI from our TRSs (three months ended March 31, 2014, annualized) were included in the foregoing table, the percent of total annualized rental income expiring would be: 2014 — 2.9%; 2015 — 4.5%; 2016 — 4.6%, 2017 — 13.2%; 2018 — 7.3%; 2019 — 6.1%; 2020 — 3.0%; 2021 — 1.3%; 2022 — 1.1% and thereafter — 56.0%. In addition, if our leases to our TRSs are included, the average remaining lease term for all properties (weighted by annualized rental income) would be 10.8 years.

(1) Excludes properties classified in discontinued operations.

(2) Excludes 7,051 living units from our managed senior living communities leased to our TRSs. If the number of living units included in our TRS leases were included in the foregoing table, the percent of total living units / beds expiring would be: 2014 — 0.0%, 2015 — 0.8%; 2016 — 0.0%; 2017 — 13.4%; 2018 — 5.1%; 2019 — 0.6%; 2020 — 0.0%; 2021 — 1.1%; 2022 — 0.0% and thereafter — 79.0%.

During the three months ended March 31, 2014, we entered into MOB lease renewals for 54,000 square feet and new leases for 37,000 square feet, at weighted average rental rates that were 5.2% below rents previously charged for the same space. These leases produce average net annual rent of $33.27 per square foot. Average lease terms for leases entered into during the first quarter of 2014 were 5.7 years. Commitments for tenant improvement, leasing commission costs and concessions for leases we entered into during the first quarter of 2014 totaled $2.0 million, or $21.56 per square foot on average (approximately $3.78 per square foot per year of the lease term).

RESULTS OF OPERATIONS (dollars and square feet in thousands, unless otherwise noted)

We have four operating segments, of which three are separately reportable operating segments: (i) triple net senior living communities that provide short term and long term residential care and dining services for residents, (ii) managed senior living communities that provide short term and long term residential care and dining services for residents and (iii) MOBs. Our triple net and managed senior living communities include independent living communities, assisted living communities and SNFs. Properties in the MOB segment include medical office, clinic and biotech laboratory buildings. The “All Other” category in the following table includes amounts related to corporate business activities and the operating results of certain properties that offer fitness, wellness and spa services to members.

our properties, before subordinated charges, if any, divided by triple-net lease minimum rents payable to us. We have not independently verified our tenants’ operating data. The table excludes data for periods prior to our ownership of some of these properties.

(3) As noted above, because Five Star has not yet filed the Five Star 2013 Form 10-K. As a result, we do not report rent coverage for the 12 months ended December 31, 2013 for this tenant or the portfolio as a whole.

Except as noted below under “Rental income”, we have not included a discussion and analysis of the results of our comparable properties data for the triple net senior living communities segment as we believe that a comparison of the results for our comparable properties for our triple net senior living communities segment is generally consistent from quarter to quarter and a separate, comparable properties comparison is not meaningful.

Rental income. Rental income decreased primarily due to the sale of the two rehabilitation hospitals during the fourth quarter of 2013, a senior living community in the third quarter of 2013 and a senior living community in the first quarter of 2014. This decrease was partially offset by our purchase of one senior living community and our purchase of approximately $35,822 of improvements made to our properties that are leased by Five Star since January 1, 2013. Rental income increased year over year on a comparable property basis by $989, primarily as a result of our improvement purchases at certain of the 219 communities we have owned continuously since January 1, 2013 and the resulting increased rent, pursuant to the terms of the leases.

Net operating income. NOI decreased because of the changes in rental income described above. We do not incur property operating expenses at our triple net senior living communities, as these expenses are paid by our tenants. Accordingly, rental income is the same as NOI. The reconciliation of NOI to net income for our triple net senior living communities segment is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation expense. Depreciation expense recognized in this segment decreased as a result of the sale of the two rehabilitation hospitals during the fourth quarter of 2013, a senior living community in the third quarter of 2013 and a senior living community in the first quarter of 2014. This decrease was partially offset by our

22

purchase of one senior living community and our purchase of improvements made to our properties that are leased by Five Star since January 1, 2013.

Interest expense. Interest expense for our triple net senior living communities arises from mortgage debt secured by certain of these properties. The decrease in interest expense is the result of the prepayment of four loans in the second quarter of 2013 that had a total principal balance of $10,377 and a weighted average interest rate of 6.1%, as well as the regularly scheduled amortization of our mortgage debt, partially offset by mortgage debt we assumed in connection with our acquisition of a triple net leased senior living community in January 2013.

Gain on sale of properties. Gain on sale of properties is a result of the sale of one senior living community in January 2014.

Residents fees and services. Residents fees and services are the revenues earned at our managed senior living communities. We recognize these revenues as services are provided. The increase in residents fees and services primarily relates to the acquisition of five managed senior living communities since January 1, 2013.

Property operating expenses. Property operating expenses include expenses incurred at our managed senior living communities and they consist of management fees, real estate taxes, utility expense, salaries and benefits of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of these operating properties. The increase in property operating expenses primarily relates to the acquisition of five managed senior living communities since January 1, 2013.

Net operating income. NOI increased because of the changes in residents fees and services and property operating expenses described above. The reconciliation of NOI to net income for our managed senior living communities segment is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

24

Depreciation expense. Depreciation expense increased primarily as a result of acquisitions of managed senior living communities since January 1, 2013.

Interest Expense. Interest expense for our managed senior living communities arises from mortgage debt secured by certain of these properties. Interest expense decreased as a result of regularly scheduled amortization of our mortgage debts.

Residents fees and services. We recognize residents fees and services as services are provided. Our residents fees and services increased year over year on a comparable property basis because of an increase in occupancy at the 39 communities we have owned continuously since January 1, 2013.

Property operating expenses. Property operating expenses consist of property management fees, real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating properties. Property operating expenses increased slightly, principally because of increases in utility expenses, real estate taxes, insurance, and other direct costs of operating properties.

Net operating income. NOI increased because of the net changes in residents fees and services less the property operating expenses described above. The reconciliation of NOI to net income for our managed senior living communities segment, comparable properties, is shown in the table above. Our definition of NOI and our consolidated reconciliation of NOI to net income are included below in “Non-GAAP Financial Measures”.

Depreciation expense. Depreciation expense increased as a result of our purchase of improvements at these properties.

Interest expense. Interest expense for our managed senior living communities arises from mortgage debts secured by certain of these properties. Interest expense decreased as a result of regularly scheduled amortization of our mortgage debts.

Net (loss) income |  | $ | 21,376 |  | $ | 21,590 |  | $ | (214 | ) | 1.0% |

Rental income. Rental income increased primarily because of rents from six MOBs (seven buildings) we acquired for approximately $117,475 since January 1, 2013. Rental income includes non-cash straight line rent adjustments totaling $1,478 and $1,538 and net amortization of approximately $(777) and $(974) of above and below market lease adjustments for the three months ended March 31, 2014 and 2013, respectively.

26

Property operating expenses. Property operating expenses consist of property management fees, real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating properties. Property operating expenses increased primarily because of our MOB acquisitions since January 1, 2013.

Net operating income. NOI increased because of the changes in rental income and property operating expenses described above. The reconciliation of NOI to net income for our MOB segment is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation / amortization expense. Depreciation / amortization expense increased primarily because of our MOB acquisitions since January 1, 2013.

Interest expense. Interest expense for our MOBs arises from mortgage debts secured by certain of these properties. The decrease in interest expense is the result of the regularly scheduled amortization of our mortgage debts.

Income from discontinued operations. Income from discontinued operations relates to the four MOBs (seven buildings) classified as held for sale as of March 31, 2014. The increase in income is primarily due to no longer depreciating the assets as of the date they met the held for sale criteria established under GAAP.

Impairment of assets from discontinued operations. During the three months ended March 31, 2014, we recorded impairment of assets charges of $721 to reduce the carrying value of two of our MOBs (five buildings) to their estimated net sale prices.

(1) Excludes properties classified in discontinued operations.

Rental income. Rental income increased slightly as a result of an increase in same store occupancy from 94.4% at March 31, 2013 to 94.8% at March 31, 2014. Rental income includes non-cash straight line rent adjustments

27

totaling $1,273 and $1,500 and net amortization of approximately $(686) and $(939) of above and below market lease adjustments for the three months ended March 31, 2014 and 2013, respectively.

Property operating expenses. Property operating expenses consist of property management fees, real estate taxes, utility expense, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating properties. Property operating expenses increased principally because of increases in utility expenses from unusually cold temperatures, landscaping (which includes snow removal), repairs and maintenance expense and other direct costs of operating properties experienced during the 2014 period.

Net operating income. NOI reflects the net changes in rental income and property operating expenses described above. The reconciliation of NOI to net income for our MOB segment for comparable properties is shown in the table above. Our definition of NOI and our reconciliation of consolidated NOI to net income are included below under the heading “Non-GAAP Financial Measures”.

Depreciation / amortization expense. Depreciation / amortization expense decreased primarily because of a reduction in amortization of acquired in place real estate leases and obligations that we amortize over the respective lease terms, partially offset by an increase in the amortization of leasing costs.

Interest expense. Interest expense for our MOBs arises from mortgage debts secured by certain of these properties. The decrease in interest expense is the result of the regularly scheduled amortization of our mortgage debts.

(1) All other operations includes our wellness center operations that we do not consider a significant, separately reportable segment of our business, home office business activities, and operating expenses that are not attributable to a specific reportable segment.

Rental income. Rental income includes non-cash straight line rent adjustments totaling approximately $138 and $365 for the three months ended March 31, 2014 and 2013, respectively. Rental income also includes net amortization of approximately $55 of acquired real estate leases and obligations in both the three months ended March 31, 2014 and 2013.

Depreciation expense. Depreciation expense remained consistent as we did not make any wellness center acquisitions or other capital improvements in this segment for the three months ended March 31, 2014 and 2013 and we generally depreciate our long lived wellness center assets on a straight line basis.

General and administrative expense. General and administrative expenses consist of fees and expenses of our trustees, fees paid to RMR under our business management agreement, equity compensation expense, legal and accounting fees and other costs relating to our status as a publicly owned company. General and administrative expenses decreased principally as a result of a decline in professional fees for the 2014 period compared to 2013.

Acquisition related costs. Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during the three months ended March 31, 2014 and 2013. Acquisition related costs decreased as a result of less senior living and MOB acquisition activity during the three months ended March 31, 2014 than the prior year period.

Impairment of assets. During the three months ended March 31, 2013, we recorded an impairment of assets charge of $1,304 related to one property to reduce its carrying value to its estimated net sale price.

Interest and other income. The decline in interest and other income reflects reduced interest earned as a result of less investable cash for the 2014 period compared with the 2013 period.

Interest expense. Interest expense decreased due to lower borrowing costs and fees under our amended revolving credit facility.

Equity in (losses) / earnings of an investee. Equity in earnings of an investee represents our proportionate share of earnings / losses from AIC.

Non-GAAP Financial Measures (dollars in thousands, except per share amounts)

We provide below calculations of our funds from operations, or FFO, Normalized FFO and NOI for the three months ended March 31, 2014 and 2013. These measures should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in our condensed consolidated statements of income and comprehensive income and condensed consolidated statements of cash flows. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. Other REITs and real estate companies may calculate FFO, Normalized FFO or NOI differently than we do.

Funds From Operations and Normalized Funds From Operations

We calculate FFO and Normalized FFO as shown below. FFO is calculated on the basis defined by the National Association of Real Estate Investment Trusts, or NAREIT, which is net income, calculated in accordance with GAAP, excluding any gain or loss on sale of properties and impairment of real estate assets, plus real estate depreciation and amortization, as well as certain other adjustments currently not applicable to us. Our calculation of Normalized FFO differs from NAREIT’s definition of FFO because we include estimated percentage rent in the period to which we estimate that it relates rather than when it is recognized as income in accordance with GAAP and exclude acquisition related costs, gain or loss on early extinguishment of debt, gain or loss on lease terminations, estimated business management incentive fees and loss on impairment of intangible assets, if any. We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, operating income and cash flow from operating activities. We believe that FFO and Normalized FFO provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense, FFO and Normalized FFO may facilitate a comparison of our operating performance between periods and with other REITs. FFO and Normalized FFO 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 status as a REIT, limitations in our revolving credit facility agreement and public debt covenants, the availability of debt and equity capital, our expectation of our future capital requirements and operating performance, and our expected needs and availability of cash to pay our obligations.

Our calculations of FFO and Normalized FFO for the three months ended March 31, 2014 and 2013 and reconciliations of net income, the most directly comparable financial measure under GAAP reported in our condensed consolidated financial statements, to FFO and Normalized FFO appear in the following table.

(1) Amounts represent estimated incentive fees under our business management agreement payable in common shares after the end of each calendar year calculated: (i) prior to 2014 based upon increases in annual Normalized FFO per share, and (ii) beginning in 2014 based on common share total return. In calculating net income in accordance with GAAP, SNH recognizes estimated business management incentive fee expense each quarter. Although SNH recognizes this expense each quarter for purposes of calculating net income, SNH does not include these amounts in the calculation of Normalized FFO until the fourth quarter, which is when the actual expense amount for the year is determined. Adjustments were made to prior period amounts to conform to current period Normalized FFO calculation.

(2) In calculating net income in accordance with GAAP, we recognize percentage rental income received for the first, second and third quarters in the fourth quarter, which is when all contingencies are met and the income is earned. Although we defer recognition of this revenue until the fourth quarter for purposes of calculating net income, we include these estimated amounts in our calculation of Normalized FFO for each quarter of the year. The fourth quarter Normalized FFO calculation excludes the amounts included during the first three quarters.

Property Net Operating Income (NOI)

We calculate NOI as shown below. 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. We consider NOI to be an appropriate supplemental measure to net income because it may help both investors and management to understand the operations of our properties. We use NOI internally to

31

evaluate individual and company wide property level performance, and we believe that NOI provides useful information to investors regarding our results of operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between periods and with other REITs. The calculation of NOI excludes certain components of net income in order to provide results that are more closely related to our properties’ results of operations.

The calculation of NOI by reportable segment is included above in this Item 2. The following table includes the reconciliation of our consolidated NOI to net income, the most directly comparable financial measure under GAAP reported in our condensed consolidated financial statements, for the three months ended March 31, 2014 and 2013.

LIQUIDITY AND CAPITAL RESOURCES

Rental income and residents fees and services revenues from our leased and managed properties and borrowings under our revolving credit facility are our principal sources of funds to pay operating expenses, debt service and distributions to shareholders. We believe that our operating cash flow will be sufficient to meet our operating expenses and debt service and pay distributions on our shares for the next 12 months and for the foreseeable future thereafter. Our future cash flows from operating activities will depend primarily upon our ability to:

· maintain or improve the occupancy of, and the current rental rates at, our properties;

· control operating cost increases at our properties; and

· purchase additional properties which produce cash flows in excess of our cost of acquisition capital and property operating expenses.

33

Our Operating Liquidity and Resources

We generally receive minimum rents monthly or quarterly from our tenants, we receive percentage rents from our triple net senior living community tenants monthly, quarterly or annually and we receive residents fees and services revenues, net of expenses, from our managed senior living communities monthly. During the three months ended March 31, 2014 and 2013, we generated $90.1 million and $73.7 million, respectively, of cash from operations. The increase in our cash from operations over the prior year primarily resulted from our property acquisitions, as further described below.

Our Investment and Financing Liquidity and Resources

At March 31, 2014, we had $33.0 million of cash and cash equivalents and $605.0 million available to borrow under our revolving credit facility. We expect to use cash balances, borrowings under our revolving credit facility, net proceeds from our property sales, net proceeds from offerings of equity or debt securities and the cash flow from our operations to fund our operations, debt repayments, distributions, future property acquisitions, expenditures related to the repair, maintenance or renovation of our properties and for other general business purposes. We believe such amounts will be sufficient to fund these activities for the next 12 months and the foreseeable future thereafter.

In order to fund acquisitions and to meet cash needs that may result from timing differences between our receipts of rents and our desire or need to make distributions or pay operating or capital expenses, we maintain a $750.0 million unsecured revolving credit facility with a group of institutional lenders. The maturity date of our revolving credit facility is January 15, 2018 and, subject to the payment of an extension fee and meeting certain other conditions, we have an option to extend the stated maturity date of our revolving credit facility by one year to January 15, 2019. In addition, our revolving credit facility includes a feature under which maximum borrowings may be increased to up to $1.5 billion in certain circumstances. Borrowings under our revolving credit facility bear interest at LIBOR plus a premium, which was 130 basis points as of March 31, 2014. We also pay a facility fee of 30 basis points per annum on the total amount of lending commitments under our revolving credit facility. Both the interest rate premium and the facility fee are subject to adjustment based upon changes to our credit ratings. We can borrow, repay and reborrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. As of March 31, 2014, the interest rate payable on borrowings under our revolving credit facility was 1.42%. The weighted average interest rate for borrowings under our revolving credit facility was 1.42% for the three months ended March 31, 2014. As of March 31, 2014 and May 2, 2014, we had $145,000 and $0 outstanding and $605,000 and $750,000 available under our revolving credit facility, respectively. For more information, see Note 5 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

When significant amounts are outstanding under our revolving credit facility or as the maturity dates of our revolving credit facility and term debts approach, we intend to explore alternatives for the repayment of amounts due. Such alternatives may include incurring additional debt, issuing new equity securities, extending the maturity date of our revolving credit facility and entering into a new credit facility. We currently have an effective shelf registration statement that allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.

In April 2014, we acquired one MOB (one building) for approximately $32,658, including the assumption of approximately $15,630 of mortgage debt, and excluding closing costs. The MOB is located in Texas and includes 125,240 square feet. We funded this acquisition using cash on hand and borrowings under our revolving credit facility.

34

In February 2014, we entered into an agreement to acquire one MOB (two buildings) for approximately $1,125,420, excluding closing costs. The MOB is located in Massachusetts and includes 1,651,037 gross building square feet. The closing of this acquisition is contingent upon closing conditions; accordingly, we can provide no assurance that we will purchase this property, that this acquisition will not be delayed or that its terms will not change.

As of March 31, 2014, we had 13 properties (16 buildings) held for sale, including nine senior living communities with 708 units and four MOBs (seven buildings) with 831,499 square feet. We decided to sell these properties because of what we believe to be unattractive conditions in the markets in which these properties are located or in which they operate. In aggregate, the nine senior living communities that are held for sale receive a majority of their revenues from Medicare / Medicaid payments. All nine of these communities are leased to Five Star and our rents from Five Star will be reduced if and as these sales occur, as determined pursuant to our leases with Five Star. During the three months ended March 31, 2014, we recorded impairment of assets charges of $0.7 million to reduce the carrying value of 2 MOBs included in discontinued operations to their estimated net sale prices. The 13 properties have a net book value (after impairment) of $26.2 million as of March 31, 2014. We are in the process of offering these 13 properties for sale, but we can provide no assurance as to when or if sales of these properties will occur or what the terms of any sale may provide. For more information about these completed and pending acquisitions and potential sales, see Note 3 to our condensed consolidated financial statements appearing in Item 1 above.

During the three months ended March 31, 2014, pursuant to the terms of our existing leases with Five Star, we purchased $8.6 million of improvements made to our properties leased to Five Star, and, as a result, the annual rent payable to us by Five Star increased by approximately $0.7 million. We used cash on hand to fund these purchases.

During the three months ended March 31, 2014 and 2013, amounts capitalized for leasing costs and building improvements at our MOBs and our capital expenditures at our managed senior living communities were as follows (dollars in thousands):

|  | Three Months Ended March 31, |
|  | 2014 |  | 2013 |
MOB tenant improvements(1) (2) |  | $ | 1,807 |  | $ | 232 |

MOB building improvements(1) (4) |  | 1,172 |  | 632 |
Managed senior living communities capital improvements |  | 2,432 |  | 2,740 |
Development, redevelopment and other activities(5) |  | 2,423 |  | 2,636 |
Total capital expenditures |  | $ | 8,518 |  | $ | 6,552 |

(1) Excludes expenditures at properties classified in discontinued operations.

(2) MOB tenant improvements generally include capital expenditures to improve tenants’ space or amounts paid directly to tenants to improve their space.

(3) MOB leasing costs generally include leasing related costs, such as brokerage commissions and other tenant inducements.

(4) MOB building improvements generally include construction costs and expenditures to replace obsolete building components that extend the useful life of existing assets.

35

(5) Development, redevelopment and other activities generally include (i) major capital expenditures that are identified at the time of a property acquisition and incurred within a short period after acquiring the property; and (ii) major capital expenditure projects that reposition a property or result in new sources of revenue.

During the three months ended March 31, 2014, commitments made for expenditures in connection with leasing space in our MOBs, such as tenant improvements and leasing costs were as follows (dollars and square feet in thousands, except per square foot amounts):

|  | New Leases |  | Renewals |  | Total |
Square feet leased during the quarter |  | 37 |  | 54 |  | 91 |
Total leasing costs and concession commitments(1) |  | $ | 1,245 |  | $ | 717 |  | $ | 1,962 |

Total leasing costs and concession commitments per square foot per year(1) |  | $ | 4.37 |  | $ | 2.66 |  | $ | 3.78 |

(1) Includes commitments made for leasing expenditures and concessions, such as tenant improvements, leasing commissions, tenant reimbursements and free rent. Excludes expenditures at properties classified in discontinued operations.

(2) Weighted based on annualized rental income pursuant to existing leases as of March 31, 2014, including straight line rent adjustments, estimated recurring expense reimbursements and excluding lease value amortization.

On April 2, 2014, we declared a quarterly distribution of $0.39 per share, or $73.4 million, to our common shareholders of record on April 14, 2014, with respect to our operating results for the quarter ended March 31, 2014; we expect to pay this distribution on or about May 21, 2014 using cash on hand and borrowings under our revolving credit facility.

In April 2014, we issued 15,525,000 common shares in a public offering, raising net proceeds of approximately $323.3 million, after underwriting discounts but before expenses. We used the net proceeds from this offering to repay borrowings outstanding under our revolving credit facility and for general business purposes, including the partial funding of the pending acquisition described above.

In April 2014, we sold $400.0 million of 3.25% senior unsecured notes due 2019 and $250.0 million of 4.75% senior unsecured notes due 2024, raising net proceeds of approximately $644.9 million, after underwriting discounts but before expenses. We plan to use the net proceeds of this offering for general business purposes, including funding the pending acquisition described above.

Simultaneous with entering the agreement to acquire the MOB in Boston, MA, we received a term loan commitment for $800.0 million from Jefferies Finance, LLC and Wells Fargo Bank, N.A. We expect that the term loan will have an interest rate of LIBOR plus 140 basis points, will mature five years from closing and can be repaid in part or whole at any time without penalty. We intend to utilize approximately $350.0 million of the commitment and may not draw the balance. The term loan is expected to be syndicated to a group of banks, and the term loan is expected to close during the second quarter of 2014. The actual amount of the term loan may change depending on our funding needs at the time of closing. The commitments which we received for the term loan are subject to various conditions, including mutually satisfactory documentation. There can be no assurance that all those conditions, some of which are beyond our control, will be satisfied, that the terms of the term loan described in the commitments will not change, or that the term loan will be available to us timely or at all.

36

We believe we will have access to various types of financings, including equity or debt offerings, to fund our future acquisitions and to pay our debts and other obligations as they become due. Our ability to complete and the costs of our future debt transactions will depend primarily upon market conditions and our credit ratings. We have no control over market conditions. Our credit ratings depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings and service our debt funding obligations, to space our debt maturities and to balance our use of equity and debt capital so that our financial performance and leverage ratios afford us flexibility to withstand any reasonably anticipatable adverse changes. We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities. However, there can be no assurance that we will be able to complete any equity or debt offerings or that our cost of any future public or private financings will not increase.

Off Balance Sheet Arrangements

As of March 31, 2014, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Debt Covenants

Our principal debt obligations at March 31, 2014 were: (1) outstanding borrowings under our $750.0 million unsecured revolving credit facility; (2) four public issuances of unsecured senior notes, including: (a) $250.0 million principal amount due 2016 at an annual interest rate of 4.30%, (b) $200.0 million principal amount due 2020 at an annual interest rate of 6.75%, (c) $300.0 million principal amount due 2021 at an annual interest rate of 6.75% and (d) $350.0 million principal amount due 2042 at an annual interest rate of 5.625%; and (3) $678.5 million aggregate principal amount of mortgages secured by 51 of our properties with maturity dates from 2014 to 2043. We had $145.0 million outstanding under our unsecured revolving credit facility as of March 31, 2014. We also have two properties encumbered by capital leases totaling $13.2 million at March 31, 2014. Our unsecured senior notes are governed by an indenture. The indenture for our unsecured senior notes and related supplements and our revolving credit facility contain a number of covenants which restrict our ability to incur debts, including debts secured by mortgages on our properties in excess of calculated amounts, require us to maintain a minimum net worth, restrict our ability to make distributions under certain circumstances and generally require us to maintain certain other financial ratios. As of March 31, 2014, we believe we were in compliance with all of the covenants under our indenture and related supplements, our revolving credit facility and our other debt obligations.

None of our indenture and related supplements, our revolving credit facility or our other debt obligations contain provisions for acceleration which could be triggered by our debt ratings. However, in certain circumstances, our revolving credit facility uses our senior debt rating to determine the fees and the interest rate payable by us.

Our public debt indenture and related supplements contain cross default provisions, which are generally triggered upon default of any of our other debts of at least $10.0 million or, with respect to certain notes under such indenture and supplements, higher amounts. Similarly, our revolving credit facility contains a cross default provision that is triggered upon default of any other debts of $25.0 million or more that are recourse debts and to any other debts of $75.0 million or more that are non-recourse debts. Our revolving credit facility agreement provides for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, such as a change of control of us, which includes RMR ceasing to act as our business manager and property manager.

37

Related Person Transactions

We have relationships and historical and continuing transactions with our Trustees, our executive officers, RMR, Five Star, AIC and other companies to which RMR provides management services and others affiliated with them. For example, we have no employees and personnel and various services we require to operate our business are provided to us by RMR pursuant to management agreements; and RMR is owned by our Managing Trustees. Also, as a further example, we have relationships with other companies to which RMR provides management services and which have trustees, directors and officers who are also trustees, directors or officers of ours or RMR, including: Five Star is our former subsidiary, our largest tenant and a manager of certain of our senior living communities, and we are Five Star’s largest stockholder; D&R Yonkers LLC is owned by our executive officers and one of our TRSs subleases a portion of a senior living community we own to it in order to accommodate certain requirements of New York healthcare licensing laws; and we, RMR, Five Star, CWH and four other companies to which RMR provides management services each currently own approximately 12.5% of AIC, and we and the other shareholders of AIC have property insurance in place providing $500.0 million of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. For further information about these and other such relationships and related person transactions, please see Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated herein by reference. In addition, for more information about these transactions and relationships, please see elsewhere in this Quarterly Report on Form 10-Q, including “Warning Concerning Forward Looking Statements” in Part I, and our Annual Report, definitive Proxy Statement for our 2014 Annual Meeting of Shareholders, or our Proxy Statement, and our other filings with the SEC, including Note 5 to our consolidated financial statements included in our Annual Report, the sections captioned “Business,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Related Person Transactions” and “Warning Concerning Forward Looking Statements” of our Annual Report and the section captioned “Related Person Transactions” and the information regarding our Trustees and executive officers in our Proxy Statement. In addition, please see the section captioned “Risk Factors” of our Annual Report for a description of risks that may arise as a result of these and other related person transactions and relationships. Our filings with the SEC, including our Annual Report and our Proxy Statement, are available at the SEC’s website at www.sec.gov. Copies of certain of our agreements with these related parties, including our business management agreement and property management agreement with RMR, our leases, forms of management agreements and related pooling agreements with Five Star, our agreements with Five Star and D&R Yonkers LLC and its owners and our shareholders agreement with AIC and its shareholders, are publicly available as exhibits to our public filings with the SEC and accessible at the SEC’s website.

We believe that our agreements with RMR, Five Star, D&R Yonkers LLC and its owners and AIC are on commercially reasonable terms. We also believe that our relationships with RMR, Five Star, D&R Yonkers LLC and its owners and AIC and their affiliated and related persons and entities benefit us and, in fact, provide us with competitive advantages in operating and growing our business.

Impact of Government Reimbursement

As of March 31, 2014, approximately 96% of our NOI was generated from properties where a majority of the NOI is derived from private resources, and the remaining 4% of our NOI was generated from properties where a majority of the NOI was derived from Medicare and Medicaid payments. We and our tenants operate facilities in many states and participate in federal and state healthcare payment programs, including the federal Medicare and state Medicaid programs for services in SNFs and other similar facilities, state Medicaid programs for services in assisted living communities, and other federal and state healthcare payment programs. Because of

38

the current federal budget deficit and other federal spending priorities and challenging state fiscal conditions, there have been numerous recent legislative and regulatory actions or proposed actions with respect to federal Medicare rates and state Medicaid rates and federal payments to states for Medicaid programs. Examples of these, and other information regarding such programs, are provided below as well as under the caption “Business—Government Regulation and Reimbursement” in our Annual Report.

The Centers for Medicare and Medicaid Services, or CMS, issued updated Medicare prospective payment system rates for SNFs effective October 1, 2013, which CMS estimates will result in a net increase of approximately 1.3% in aggregate Medicare payments for SNFs in federal fiscal year 2014. As of March 26, 2014, 19 states have elected not to broaden Medicaid eligibility under the the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, and five remain undecided; those states that ultimately choose not to participate in Medicaid expansion will forgo the federal funds that would otherwise be available for that purpose.

On April 1, 2014, the Protecting Access to Medicare Act of 2014, or PAMA, extended the Medicare outpatient therapy cap exception process through March 31, 2015, further postponing the implementation of limits on Medicare payments for outpatient therapies. PAMA also extended the 0.5% increase to the Medicare Physician Fee Schedule, or MPFS, rates through December 31, 2014 and provided no increase in the MPFS rates in the period between January 1, 2015 and March 31, 2015. Unless further delayed, the MPFS rates are scheduled to be reduced by up to 24% effective April 1, 2015. Additionally, PAMA established a SNF value-based purchasing program. Under this program, the United States Department of Health and Human Services will assess SNFs based on hospital readmissions measures and make these assessments available to the public no later than October 1, 2017. Beginning in federal fiscal year 2019, SNFs will face a two percent withholding of SNF payments and will receive incentive payments based on the higher of their performance or improvement on certain hospital readmission measures. The collective amount of incentive payments to all SNFs are anticipated to be between 50% and 70% of the total payment amounts withheld. We are unable to predict the impact on us of these or other recent legislative and regulatory actions or proposed actions with respect to federal Medicare rates, state Medicaid rates, and the federal payments to states for Medicaid programs.

The ACA includes various provisions affecting Medicare and Medicaid providers, including expanded public disclosure requirements for SNFs and other providers, enforcement reforms, and increased funding for Medicare and Medicaid program integrity control initiatives. The ACA has resulted in several changes to existing healthcare fraud and abuse laws, established additional enforcement tools and funding to the government, and provided for increased cooperation between agencies by establishing mechanisms for sharing information relating to noncompliance. Furthermore, the ACA provides for enhanced criminal and administrative penalties for noncompliance. We are unable to predict the impact on our tenants and our managers of the insurance reforms, payment reforms, and healthcare delivery systems reforms contained in and to be developed pursuant to the ACA. Expanded insurance availability could provide more paying customers to our tenants and managers. On the other hand, if the changes to be implemented under the ACA result in reduced payments for the services that our tenants or our managers provide or the failure of Medicare, Medicaid or insurance payment rates to cover our tenants’ costs, including the rents and management fees that they pay, our future financial results could be adversely and materially affected.

We cannot estimate the type and magnitude of the potential regulatory changes discussed above, but they may have a material adverse effect on the ability of our tenants to pay us rent, the profitability of our managed senior living communities and the values of our properties. The changes implemented or to be implemented could result in the failure of Medicare, Medicaid or private payment rates to cover our or our tenants’ costs of providing required services to residents, in reductions in payments or other circumstances that

39

could have a material adverse effect on the ability of our tenants to pay rent to us, the profitability of our managed senior living communities and the values of our properties.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to risks associated with market changes in interest rates. We manage our exposure to this market risk by monitoring available financing alternatives. Our strategy to manage exposure to changes in interest rates has not materially changed since December 31, 2013. Other than as described below, we do not currently foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

At March 31, 2014, our outstanding fixed rate debt included the following (dollars in thousands):

Debt |  | Principal Balance(1) |  | Annual Interest Rate(1) |  | Annual Interest Expense |  | Maturity |  | Interest Payments Due |

|  | $ | 1,778,514 |  |  |  | $ | 106,975 |  |  |  |  |

(1) The principal balances and interest rates are the amounts stated in the applicable contracts. In accordance with GAAP, our carrying values and recorded interest expense may differ from these amounts because of market conditions at the time we assumed these debts. This table does not include obligations under capital leases and excludes $400.0 million principal balance of our 3.25% senior notes due 2019 and $250.0 million principal balance of our 4.75% senior notes due 2024 issued by us in April 2014, and an $800.0 million term loan commitment in connection with the acquisition of one MOB (two buildings). Also excludes secured fixed rate debt of $15.6 million with an interest rate of 6.28% assumed in connection with the acquisition of one MOB in April 2014.

No principal repayments are due under our unsecured notes or bonds until maturity. Our mortgages require principal and interest payments through maturity pursuant to amortization schedules. Because these

41

debts bear interest at a fixed rate, changes in market interest rates during the term of these debts will not affect our interest obligations. If these debts were refinanced at interest rates which are 100 basis points higher or lower than shown above, our annual interest cost would increase or decrease by approximately $10.7 million.

Changes in market interest rates would affect the fair value of our fixed rate debt obligations; increases in market interest rates decrease the fair value of our fixed rate debt, while decreases in market interest rates increase the fair value of our fixed rate debt. Based on the balances outstanding at March 31, 2014, and discounted cash flow analyses through the respective maturity dates and assuming no other changes in factors that may affect the fair value of our fixed rate debt obligations, a hypothetical immediate 100 basis point change in interest rates would change the fair value of those obligations by approximately $26.1 million.

Our unsecured senior notes and some of our mortgages contain provisions that allow us to make repayments earlier than the stated maturity date. In some cases, we are not allowed to make early repayment prior to a cutoff date and we are generally allowed to make prepayments only at a premium equal to a make whole amount, as defined, which is generally designed to preserve a stated yield to the noteholder. In the past, we have repurchased and retired some of our outstanding debts and we may do so again in the future. These prepayment rights and our ability to repurchase and retire outstanding debt may afford us opportunities to mitigate the risk of refinancing our debts at maturity at higher rates by refinancing prior to maturity.

Our only current floating rate obligations are under our $750.0 million unsecured revolving credit facility and we had $145.0 million of borrowings outstanding as of March 31, 2014 under that credit facility. Our revolving credit facility matures in January 2018, and, subject to our meeting certain conditions, including our payment of an extension fee, we have the option to extend the stated maturity date by one year to January 2019. No principal repayments are required under our revolving credit facility prior to maturity, and prepayments may be made, and redrawn subject to conditions, at any time without penalty. Borrowings under our revolving credit facility are in U.S. dollars and bear interest at LIBOR plus a premium that is subject to adjustment based upon changes to our credit ratings. Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR. There have been recent governmental inquiries regarding the setting of LIBOR, which may result in changes to the process that could have the effect of increasing LIBOR. In addition, upon renewal or refinancing of our revolving credit facility, we are vulnerable to increases in interest rate premiums due to market conditions or our perceived credit risk. Generally, a change in interest rates would not affect the value of our floating rate debt but would affect our operating results. The following table presents the impact a 100 basis point increase in interest rates would have on our annual floating rate interest expense at March 31, 2014:

|  | Impact of Changes in Interest Rates |
|  | Interest Rate(1) |  | Outstanding Debt |  | Total Interest Expense Per Year |  | Annual Earnings per Share Impact(2) |
At March 31, 2014 |  | 1.42% |  | $ | 145,000 |  | $ | 2,059 |  | $ | 0.01 |
100 basis point increase |  | 2.42% |  | $ | 145,000 |  | $ | 3,509 |  | $ | 0.02 |

(1) Weighted based on the outstanding borrowings for the three months ended March 31, 2014.

(2) Based on weighted average number of shares outstanding for the three months ended March 31, 2014.

The following table presents the impact a 100 basis point increase in interest rates would have on our annual floating rate interest expense at March 31, 2014 if we had fully drawn our revolving credit facility (dollars in thousands):

42

|  | Impact of Changes in Interest Rates |
|  | Interest Rate(1) |  | Outstanding Debt |  | Total Interest Expense Per Year |  | Annual Earnings per Share Impact(2) |
At March 31, 2014 |  | 1.42% |  | $ | 750,000 |  | $ | 10,650 |  | $ | 0.06 |
100 basis point increase |  | 2.42% |  | $ | 750,000 |  | $ | 18,150 |  | $ | 0.10 |

(1) Weighted based on the outstanding borrowings as of March 31, 2014 assuming we were fully drawn on our revolving credit facility.

(2) Based on weighted average number of shares outstanding for the three months ended March 31, 2014.

The foregoing two tables show the impact of an immediate change in floating interest rates. If interest rates were to change gradually over time, the impact would be spread over time. Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount of our borrowings under our revolving credit facility or other floating rate debt.

Item 4. Controls and Procedures.

As of the end of the period covered by this report, our management carried out an evaluation, under the supervision and with the participation of our Managing Trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to the Securities Exchange Act of 1934, as amended, Rules 13a-15 and 15d-15. Based upon that evaluation, our Managing Trustees, President and Chief Operating Officer and Treasurer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On February 7, March 7 and April 7, 2014, we issued 10,311, 9,626 and 10,342 of our common shares, respectively, to RMR as payment of a portion of the management fee due to RMR pursuant to our current business management agreement with RMR. We issued these shares pursuant to an exemption from registration contained in Section 4(a)(2) of the Securities Act.

Item 5. Other Information.

As discussed elsewhere in this Quarterly Report on Form 10-Q, we and Five Star have entered into AL Pooling Agreements which pool our management agreements with Five Star for communities that include assisted living units. On April 29, 2014, effective as of November 1, 2013, we and Five Star entered into a third AL Pooling Agreement which includes our management agreement with Five Star for a property that we acquired in November 2013 and which we expect to be amended in the future to include additional properties that we acquire and that are managed by Five Star, if any.

The terms of the third AL Pooling Agreement are substantially similar to the terms of the existing AL Pooling Agreements. Descriptions of the AL Pooling Agreements appear in Note 5 to our Consolidated Financial Statements included in our Annual Report and in the sections of our Annual Report captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Portfolio Overview,” which descriptions are hereby incorporated by reference.
