Select Income REIT Announces Second Quarter Results

Generates Normalized FFO of $0.72 Per Share

Increases Rental Rates for New and Renewal Leases by 21% and Hawaii Rent Resets by 30.9%

Increases Occupancy to 96.1% and Acquires Two Properties for $208 Million

Newton, MA (July 28, 2014): Select Income REIT (NYSE: SIR) today announced financial results for the quarter and six months ended June 30, 2014.

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

“Select Income REIT generated solid results across the board in the second quarter, reporting increased occupancy, while also maintaining its track record of strong double digit leasing/rent reset increases in Hawaii. Additionally, we acquired two mainland properties and better positioned the company for continued growth by substantially lowering leverage through our May 2014 equity offering.”

Results for the Quarter Ended June 30, 2014:

Normalized funds from operations, or Normalized FFO, for the quarter ended June 30, 2014 were $39.2 million, or $0.72 per share, compared to Normalized FFO for the quarter ended June 30, 2013 of $30.4 million, or $0.77 per share. Net income was $30.2 million, or $0.56 per share, for the quarter ended June 30, 2014, compared to $22.8 million, or $0.58 per share, for the same quarter last year.  The decline in Normalized FFO per share and net income per share for the quarter ended June 30, 2014 primarily resulted from the increase in SIR’s weighted average number of common shares outstanding from 39.3 million for the quarter ended June 30, 2013 to 54.2 million for the quarter ended June 30, 2014, which was partially offset by increases in Normalized FFO and net income from recent acquisitions and positive leasing/rent resets at SIR’s Hawaii properties.

A reconciliation of net income determined in accordance with U.S. generally accepted accounting principles, or GAAP, to FFO, and Normalized FFO and of NOI to net income determined in accordance with GAAP for the quarters ended June 30, 2014 and 2013 appears later in this press release.

Results for the Six Months Ended June 30, 2014:

Normalized funds from operations, or Normalized FFO, for the six months ended June 30, 2014 were $75.6 million, or $1.45 per share, compared to Normalized FFO for the six months ended June 30, 2013 of $60.5 million, or $1.54 per share. Net income was $55.3 million, or $1.06 per share, for the six months ended June 30, 2014, compared to $45.4 million, or $1.16 per share, for the six months ended June 30, 2013. The decline in Normalized FFO per share and net income per share for the six months ended June 30, 2014 primarily resulted from the increase in SIR’s weighted average number of common shares outstanding from 39.3 million for the six months ended June 30, 2013 to 52.0 million for the six months ended June 30, 2014, which was partially offset by an increase in Normalized FFO and net income from recent acquisitions and positive leasing/rent resets at SIR’s Hawaii properties.

A reconciliation of net income determined in accordance with GAAP to FFO, and Normalized FFO and of NOI to net income determined in accordance with GAAP for the six months ended June 30, 2014 and 2013 appears later in this press release.

Occupancy and Leasing Results:

SIR entered into new leases for approximately 91,000 square feet and lease renewals for approximately 148,000 square feet during the quarter ended June 30, 2014, which resulted in combined weighted average rental rates that were approximately 21.0% higher than prior rents for the same space.  The weighted average lease term for leases entered into during the second quarter of 2014 was 7.0 years.  Commitments for tenant improvements, leasing commission costs and concessions for leases entered into during the quarter ended June 30, 2014 totaled approximately $647,000, or approximately $0.39 per square foot per year of the weighted average lease term.  All leasing activity during the quarter ended June 30, 2014 occurred at SIR’s Hawaii properties.

During the quarter ended June 30, 2014, SIR also completed 11 rent resets at properties located in Hawaii for approximately 721,000 square feet of land at combined weighted average reset rates that were approximately 30.9% higher than prior rates.

As of June 30, 2014, 96.1% of SIR’s total rentable square feet was leased, compared to 95.5% leased as of June 30, 2013, and 95.7% leased as of March 31, 2014. Occupancy for properties owned continuously since April 1, 2013 increased to 95.8% at June 30, 2014 from 95.5% at June 30, 2013. Same property NOI increased 1.1% during the three months ended June 30, 2014, largely as a result of rent resets and leasing activity in Hawaii since July 1, 2013.

Recent Investment Activities:

Since April 1, 2014, SIR has acquired two properties with approximately 987,000 of combined square feet for an aggregate purchase price of $207.9 million, excluding closing costs:

(1)       SIR 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, calculated in accordance with GAAP, plus real estate depreciation and amortization, as well as certain other adjustments currently not applicable to SIR. SIR’s calculation of Normalized FFO differs from NAREIT’s definition of FFO because SIR excludes acquisition related costs, estimated business management incentive fees and gain on early extinguishment of debt.  SIR considers 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. SIR 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 its operating performance between periods and with other REITs. FFO and Normalized FFO are among the factors considered by SIR’s Board of Trustees when determining the amount of distributions to SIR’s shareholders. Other factors include, but are not limited to, requirements to maintain SIR’s status as a REIT, limitations in SIR’s revolving credit facility agreement and term loan agreement, the availability of debt and equity capital, SIR’s expectation of its future capital requirements and operating performance, and SIR’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, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of SIR’s financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of SIR’s needs. These measures should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in SIR’s Condensed Consolidated Statements of Income and Comprehensive Income and Condensed Consolidated Statements of Cash Flows. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than SIR does.

(2)       Amounts represent estimated incentive fees under our business management agreement payable in SIR’s common shares after the end of each calendar year calculated: (i) prior to 2014 based on increases in annual FFO per share (as defined), and (ii) beginning in 2014 based upon common share total return. In calculating net income in accordance with GAAP, SIR recognizes estimated business management incentive fee expense each quarter.  Although SIR recognizes this expense each quarter for purposes of calculating net income, SIR 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. The negative amount for this fee for the 2014 second quarter reflects the reversal recognized for that quarter of the amount by which the estimated 2014 incentive fee accrued as of March 31, 2014 exceeded the amount of that fee estimated as of June 30, 2014. Adjustments were made to prior period amounts to conform to the current period Normalized FFO calculation.

Calculation and Reconciliation of Property Net Operating Income(1)

(amounts in thousands)

(1)       SIR calculates NOI as shown above.  SIR defines NOI as income from its rental of real estate less property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions. SIR considers NOI to be an appropriate supplemental measure to net income because it may help both investors and management to understand the operations of SIR’s properties.  SIR uses NOI to evaluate individual and company wide property level performance, and SIR believes that NOI provides useful information to investors regarding its results of operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of SIR’s 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 SIR’s properties’ results of operations. NOI does not represent cash generated by operating activities in accordance with GAAP, and should not be considered as an alternative to net income, operating income or cash flow from operating activities, determined in accordance with GAAP, or as an indicator of SIR’s financial performance or liquidity, nor is this measure necessarily indicative of sufficient cash flow to fund all of SIR’s needs.  This measure should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in SIR’s Condensed Consolidated Statements of Income and Comprehensive Income and Condensed Consolidated Statements of Cash Flows.  Other REITs and real estate companies may calculate NOI differently than SIR does.
