Year End 2015 Results

Normalized FFO Per Share for the Fourth Quarter Increases 5% Year over Year to $0.61

New and Renewal Leases Entered During the Fourth Quarter for 204,833 Square Feet

Occupancy Increases 100 bps Sequentially Compared to the Previous Quarter

Newton, MA (February 18, 2016): Government Properties Income Trust (NYSE: GOV) today announced its financial results for the quarter and year ended December 31, 2015.

David Blackman, President and Chief Operating Officer of GOV, made the following statement:

“Government Properties Income Trust had an active fourth quarter of 2015.  We executed leases for almost 205,000 square feet, with approximately 93% of this leasing activity with government tenants.  Our leasing included approximately 110,000 square feet of positive absorption that increased occupancy by 100 bps from the third quarter of 2015.  As of the quarter end, over 93% of our rents came from government tenants.”

Results for the Quarter Ended December 31, 2015:

Normalized funds from operations, or Normalized FFO, for the quarter ended December 31, 2015 were $43.6 million, or $0.61 per diluted share, compared to Normalized FFO for the quarter ended December 31, 2014 of $40.7 million, or $0.58 per diluted share. The increase in Normalized FFO per share for the quarter ended December 31, 2015 was primarily the result of an increase in Normalized FFO attributable to GOV’s investment in Select Income REIT (NYSE: SIR).

Net loss determined in accordance with U.S. generally accepted accounting principles, or GAAP, was $2.3 million, or $0.03 per diluted share, for the quarter ended December 31, 2015, compared to net income of $14.1 million, or $0.20 per diluted share, for the quarter ended December 31, 2014. The net loss for the quarter ended December 31, 2015 included non-cash loss on the distribution of shares of class A common stock of The RMR Group Inc. (NASDAQ: RMR) common stock to GOV’s shareholders totaling $12.4 million, or $0.17 per diluted share. The weighted average number of diluted common shares outstanding was 71.0 million for the quarter ended December 31, 2015, and 70.3 million for the quarter ended December 31, 2014.

increase in Normalized FFO per share for the year ended December 31, 2015 was primarily the result of an increase in Normalized FFO attributable to GOV’s investment in SIR.

The weighted average number of diluted common shares outstanding was 70.7 million for the year ended December 31, 2015, and 61.4 million for the year ended December 31, 2014.

Reconciliations of net income (loss) determined in accordance with GAAP to FFO and Normalized FFO for the years ended December 31, 2015 and 2014 appear later in this press release.

Leasing, Occupancy and Same Property Results:

During the quarter ended December 31, 2015, GOV entered into new and renewal leases for 204,833 rentable square feet at weighted (by rentable square feet) average rental rates that were 13.1% below prior rents for the same space.  The weighted average (by rentable square feet) lease term for leases entered into during the quarter ended December 31, 2015 was 6.4 years.  Leasing capital commitments for new and renewal leases entered into during the quarter ended December 31, 2015 were $11.3 million, or $8.65 per square foot, per lease year.

As of December 31, 2015, 94.5% of GOV’s rentable square feet at properties classified as continuing operations was leased. This compares with 93.5% as of September 30, 2015 and 94.9% as of December 31, 2014.  Occupancy for properties owned continuously since October 1, 2014, excluding properties classified as discontinued operations, or same properties, was 94.5% as of December 31, 2015, which compares with 94.7% as of December 31, 2014. Same properties cash basis net operating income, or Cash Basis NOI, decreased 6.2% for the quarter ended December 31, 2015 compared to the same period in 2014.

Reconciliations of net income (loss) determined in accordance with GAAP to NOI and to Cash Basis NOI for the quarters ended December 31, 2015 and 2014 appear later in this press release.

Recent Acquisition Activities:

In January 2016, GOV acquired an office property (one building) located in Sacramento, CA with 338,796 rentable square feet for a purchase price of $79.8 million, excluding acquisition related costs.  The property is majority leased to the State of California for a remaining lease term of 7.0 years as of the date of acquisition.

Financing Activities:

In January 2016, GOV gave notice to repay at par, an $83.0 million mortgage note requiring interest at 5.55% which is secured by one office property (two buildings) located in Reston, VA.  GOV expects to repay this mortgage note in March 2016.  This mortgage note is scheduled to mature in April 2016.

In February 2016, GOV repaid at par, a $23.5 million mortgage note requiring interest at 6.21% which was secured by an office property (one building) located in Landover, MD.  This mortgage note was scheduled to mature in August 2016.

Distribution of RMR Common Stock:

On December 14, 2015, GOV distributed to common shareholders 0.0108 shares of RMR common stock for each common share of GOV held as of the close of business on November 27, 2015.  In connection with this distribution, GOV recognized a non-cash loss of $12.4 million because the closing price of RMR common stock was lower than GOV’s carrying amount per share on the day RMR common stock was distributed to GOV’s shareholders.  Since the distribution date, the trading price of RMR common stock has increased.  If the trading price of RMR common stock on the

2

distribution date had been at the current increased price per share, GOV would have recognized a lesser non-cash loss on the distribution.

Funds from Operations and Normalized Funds from Operations(1)

(amounts in thousands, except per share data)

(unaudited)

(1)             GOV calculates FFO and Normalized FFO as shown above. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or NAREIT, which is net income (loss), calculated in accordance with GAAP, plus real estate depreciation and amortization and the difference between FFO attributable to an equity investment and equity in earnings of an equity investee but excluding impairment charges on real estate assets, carrying value adjustments of real estate assets held for sale, any gain or loss on sale of properties, as well as certain other adjustments currently not applicable to GOV. GOV’s calculation of Normalized FFO differs from NAREIT’s definition of FFO because GOV includes the difference between FFO and Normalized FFO attributable to GOV’s equity investment in SIR, GOV includes estimated business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP and GOV excludes acquisition related costs, gains or losses on early extinguishment of debt, loss on impairment of SIR investment, losses on issuance of shares by SIR and loss on distribution to common shareholders of RMR common stock. GOV considers FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income (loss), operating income and cash flow from operating activities. GOV believes 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 GOV’s operating performance between periods and with other REITs. FFO and Normalized FFO are among the factors considered by GOV’s Board of Trustees when determining the amount of distributions to its shareholders. Other factors include, but are not limited to, requirements to maintain GOV’s qualification for taxation as a REIT, limitations in GOV’s credit agreement and public debt covenants, the availability to GOV of debt and equity capital, GOV’s expectation of its future capital requirements and operating performance, GOV’s receipt of distributions from SIR and GOV’S expected needs and availability of cash to pay its obligations. FFO and Normalized FFO do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income (loss), operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of GOV’s financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of GOV’s needs. These measures should be considered in conjunction with net income (loss), operating income and cash flow from operating activities as presented in GOV’s Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Cash Flows. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than GOV does.

(2)             Amounts represent a non-cash loss recorded as a result of the closing price of RMR common stock being lower than GOV’s carrying amount per share on the day RMR common stock was distributed to GOV’s shareholders.

Calculation and Reconciliation of Property Net Operating Income (NOI) and Cash Basis NOI(1)

(amounts in thousands)

(unaudited)

(1)             GOV calculates NOI and Cash Basis NOI as shown above.  The calculations of NOI and Cash Basis NOI exclude certain components of net income (loss) in order to provide results that are more closely related to GOV’s property level results of operations. GOV defines NOI as income from its rental of real estate less its property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions. GOV defines Cash Basis NOI as NOI excluding non-cash straight line rent adjustments, lease value amortization, and non-cash amortization included in other operating expenses.  GOV considers NOI and Cash Basis NOI to be appropriate supplemental measures to net income (loss) because they may help both investors and management to understand the operations of GOV’s properties. GOV uses NOI and Cash Basis NOI to evaluate individual and company wide property level performance, and GOV believes that NOI and

7

Cash Basis NOI provide useful information to investors regarding GOV’s results of operations because they reflect only those income and expense items that are generated and incurred at the property level and may facilitate comparisons of GOV’s operating performance between periods and with other REITs.  NOI and Cash Basis NOI do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income (loss), 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 GOV’s needs. These measures should be considered in conjunction with net income (loss), operating income and cash flow from operating activities as presented in GOV’s Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Cash Flows. Other REITs and real estate companies may calculate NOI and Cash Basis NOI differently than GOV does.

(2)             Excludes properties classified as discontinued operations.

(3)             GOV reports rental income on a straight line basis over the terms of the respective leases; as a result, rental income includes non-cash straight line rent adjustments.  Rental income also includes expense reimbursements, tax escalations, parking revenues, service income and other fixed and variable charges paid to GOV by its tenants, as well as the net effect of non-cash amortization of intangible lease assets and liabilities.

(4)             GOV recorded a liability for the amount by which the estimated fair value for accounting purposes exceeded the price GOV paid for its investment in RMR common stock in June 2015. A portion of this liability is being amortized on a straight line basis through December 31, 2035, the then 20 year life of GOV’s property management agreement with the operating subsidiary of RMR, as a reduction to property management fees, which are included in other operating expenses.

(5)             Amounts represent a non-cash loss recorded as a result of the closing price of RMR common stock being lower than GOV’s carrying amount per share on the day RMR common stock was distributed to GOV’s shareholders.

(6)             For the three months ended December 31, 2015, based on properties GOV owned as of December 31, 2015, and which it owned continuously since October 1, 2014, excluding properties classified as discontinued operations.

(7)             For the year ended December 31, 2015, based on properties GOV owned as of December 31, 2015, and which it owned continuously since January 1, 2015, excluding properties classified as discontinued operations.
