TIER REIT, Inc. (NYSE: TIER), a Dallas-based real estate investment trust that specializes in owning and operating best-in-class office properties in select U.S. markets, today announced financial and operating results for the fourth quarter and full year ended December 31, 2017.

Fourth Quarter & Full Year 2017 Highlights

• Recognized a net loss of $0.21 per diluted common share for the fourth quarter and net income of $1.75 per diluted common share for the full year 2017
• Reported Funds from Operations (FFO) attributable to common stockholders of $0.39 per diluted common share for the fourth quarter and $1.50 per diluted common share for the full year 2017
• Reported FFO, Excluding Certain Items, attributable to common stockholders of $0.40 per diluted common share for the fourth quarter and $1.57 per diluted common share for the full year 2017
• Recognized Same Store NOI Growth of 3.1% for the full year 2017
• Recognized Same Store Cash NOI Growth of 4.2% for the full year 2017
• Increased occupancy by 80 basis points during the fourth quarter to 89.1% at December 31, 2017

“We continue to make strong progress on our strategic plan,” stated Scott W. Fordham, President & Chief Executive Officer, “and are pleased to have successfully executed on our key objectives this past year.”

“We exited five markets during 2017,” continued Mr. Fordham, “and we announced today that we are under contract on 500 East Pratt in Baltimore, Loop Central in Houston, and Centreport Office Center in Fort Worth. Exiting Baltimore and downsizing our Houston and Fort Worth portfolios will further our continued efforts to sharpen our geographic footprint and improve the overall quality of our portfolio. Subject to normal closing conditions, we expect to complete these transactions during the first quarter.”

“Looking forward, we are excited by the opportunity to continue creating value within Austin,” added Mr. Fordham. “This includes our recent acquisition of Domain Point, which is comprised of two office buildings that total approximately 240,000 square feet on over 9.5 acres of land. As part of our acquisition, we exercised our exclusive rights to rebrand and include the property as part of The Domain, bringing our total Austin office ownership to over 2.1 million square feet, including properties under construction that are over 95% leased.”

“We’ve always known Austin is a special city,” remarked Mr. Fordham, “and we are pleased to see its prominence grow not only within our portfolio, but also as one of the nation’s most desirable places to live, work and play. Our existing ability to develop at least 1.2 million square feet inside The Domain, plus future redevelopment opportunities, positions us for significant additional value creation opportunities within Austin.”

Fourth Quarter & Full Year Financial Results

For the fourth quarter of 2017, net loss attributable to common stockholders was $9.9 million, or $0.21 per diluted common share, as compared to a net loss of $6.3 million, or $0.13 per diluted common share, for the fourth quarter of 2016. For the full year 2017, net income was $84.3 million, or $1.75 per diluted common share, as compared to a net loss of $29.4 million, or $0.62 per diluted common share, for 2016.

For the fourth quarter of 2017, NAREIT-defined FFO attributable to common stockholders was $19.0 million, or $0.39 per diluted common share, as compared to $18.9 million, or $0.40 per diluted common share, for the fourth quarter of 2016. For 2017, NAREIT-defined FFO was $71.9 million, or $1.50 per diluted common share, as compared to $76.5 million, or $1.60 per diluted common share, for 2016.

For the fourth quarter of 2017, FFO attributable to common stockholders, excluding certain items, was $19.4 million, or $0.40 per diluted common share, as compared to $19.1 million, or $0.40 per diluted common share, for the fourth quarter of 2016. For the full year 2017, FFO, excluding certain items, was $75.1 million, or $1.57 per diluted common share, as compared to $79.5 million, or $1.66 per diluted common share, for 2016.

Property Results

Our occupancy at December 31, 2017, was 89.1%, an increase of 80 basis points from September 30, 2017.

During the fourth quarter of 2017, we leased 165,000 square feet, which included 30,000 square feet of renewals, 2,000 square feet of expansions, and 133,000 square feet of new leasing.

During the fourth quarter of 2017, we continued to abate rent at One & Two Eldridge Place and Three Eldridge Place (collectively known as the “Eldridge Properties”), located in Houston, Texas, because the properties had not been restored to pre-loss condition following Hurricane Harvey. Rent abatements of $5.1 million and $7.0 million were provided to tenants for the fourth quarter of 2017 and for the year, respectively. A total of $6.2 million of these losses was recovered from business interruption insurance proceeds in the fourth quarter, which included $1.9 million for the third quarter and $4.3 million for the fourth quarter, net of a deductible and estimated saved expenses.

Subsequent to quarter end, the total office space leased at our Third + Shoal development property increased to over 90% (88.7% of the total rentable space).

Real Estate Activity

Subsequent to quarter end, on January 4, 2018, we acquired a 96.5% promoted economic interest in Domain Point. Domain Point is located in Austin, Texas, adjacent to our other Domain office properties and includes two buildings with 240,000 rentable square feet (combined).

Further, we are currently under contract to sell three properties that are outside of our target growth markets or our target submarkets. These properties consist of 500 East Pratt, located in Baltimore, Maryland, with approximately 280,000 rentable square feet; Loop Central, located in Houston, Texas, with approximately 575,000 rentable square feet; and Centreport Office Center, located in Fort Worth, Texas, with approximately 133,000 rentable square feet. These properties are under contracts for an aggregate anticipated sales price of approximately $145.0 million, and each is expected to close during the first quarter of 2018. The sale of each of these properties is subject to closing conditions, and there is no assurance we will sell these properties on the terms or timing we expect or at all.

Capital Markets Activity

On October 27, 2017, we entered into a construction loan secured by Third + Shoal with available borrowings of up to $103.8 million (at 100%). The loan is scheduled to mature in October 2021, with two, one-year extension options, subject to certain conditions and our payment of an extension fee.

On November 3, 2017, our board of directors authorized a distribution of $0.18 per share of common stock for the fourth quarter of 2017, which was paid on December 29, 2017.

Subsequent to quarter end, on February 7, 2018, our board of directors authorized a distribution of $0.18 per share of common stock for the first quarter of 2018, payable on March 29, 2018.

Subsequent to quarter end, on January 18, 2018, we amended our existing multi-bank unsecured credit facility. The amendment provides for total unsecured borrowings under the credit facility to increase from $860 million to $900 million, with the ability to further increase total borrowings by up to an additional $300 million in the aggregate subject to certain requirements. The revolving line of credit was increased to $325 million and the maturity date extended from December 2018 to January 2022, which can be extended one additional year subject to certain conditions and our payment of an extension fee, and the maturity date of the $300 million term loan was extended from December 2019 to January 2025.

Appointment of Certain Officers

On February 8, 2018, our board of directors appointed Dallas E. Lucas as our President and Chief Operating Officer, James E. Sharp as our Chief Financial Officer and Treasurer, and Hannah Wrenn as our Chief Accounting Officer, in each case effective as of February 15, 2018. Mr. Fordham will remain our Chief Executive Officer and a director.

Approximately $6.2 million of these losses were recovered from business interruption insurance proceeds, net of a deductible and estimated saved expenses.   (1)   Includes our pro rata share of consolidated and unconsolidated amounts, including for our period of ownership of properties sold. (2) Interest rate swaps are adjusted to fair value through other comprehensive income (loss). However, because our interest rate swaps do not have a LIBOR floor while the hedged debt is subject to a LIBOR floor, the portion of the change in fair value of our interest rate swaps attributable to this mismatch is reclassified to interest rate hedge ineffectiveness income within “interest expense” on our consolidated statements of operations and comprehensive income (loss). (3) We have a non-recourse loan in default which subjects us to incur default interest at a rate that is 500 basis points higher than the stated interest rate. Although there can be no assurance, we anticipate that when this property is sold or when ownership of this property is conveyed to the lender, this default interest will be forgiven. (4) There are no dilutive securities for purposes of calculating net loss per common share.     Same Store NOI and Same Store Cash NOI (in thousands, except percentages)       Three Months Ended     Year Ended December 31,     December 31, December 31,     December 31, 2017 2016 2017 2016 Same Store Revenue: Rental revenue (1) $ 44,342 $ 42,165 $ 170,997 $ 173,005 Less: Lease termination fees   (254 )   (62 )   (463 )   (1,504 )   44,088     42,103     170,534     171,501     Same Store Expenses: Property operating expenses (less tenant improvement demolition costs) 11,836 11,920 44,872 46,375 Real estate taxes 7,032 6,730 28,463 29,154 Property management fees   25     42     91     192   Property Expenses   18,893     18,692     73,426     75,721   Same Store NOI - consolidated properties 25,195 23,411 97,108 95,780 Same Store NOI - unconsolidated properties (at ownership %)   1,326     1,266     5,394     3,605   Same Store NOI $ 26,521   $ 24,677   $ 102,502   $ 99,385     Increase (decrease) in Same Store NOI 7.5 % 3.1 %   Same Store NOI - consolidated properties $ 25,195 $ 23,411 $ 97,108 $ 95,780 Less: Straight-line rent revenue adjustment (505 ) (1,283 ) (5,558 ) (5,269 ) Amortization of above- and below-market rents, net   (656 )   (853 )   (2,586 )   (4,101 ) Same Store Cash NOI - consolidated properties 24,034 21,275 88,964 86,410 Same Store Cash NOI - unconsolidated properties (at ownership %)   1,104     1,249     4,418     3,225   Same Store Cash NOI $ 25,138   $ 22,524   $ 93,382   $ 89,635     Increase in Same Store Cash NOI 11.6 % 4.2 %   Reconciliation of net income (loss) to Same Store NOI and Same Store Cash NOI Net income (loss) $ (9,884 ) $ (6,341 ) $ 84,327 $ (29,453 ) Adjustments: Interest expense 8,155 8,565 33,576 43,257 Asset impairment losses 5,250 — 5,250 8,977 Tenant improvement demolition costs 25 277 267 722 General and administrative 4,956 5,796 21,446 23,649 Depreciation and amortization 23,788 23,856 94,754 111,830 Interest and other income (88 ) (303 ) (1,359 ) (1,169 ) Loss on early extinguishment of debt — — 545 — Provision for income taxes 171 188 468 655 Equity in operations of investments (32 ) (685 ) (6,399 ) (2,569 ) Gain on sale of assets (384 ) (650 ) (92,396 ) (22,176 ) Gain on remeasurement of investment in unconsolidated entities — — (14,168 ) — Net operating income of non-same store properties (6,508 ) (7,230 ) (28,740 ) (36,439 ) Lease termination fees (254 ) (62 ) (463 ) (1,504 ) Same Store NOI of unconsolidated properties (at ownership %)   1,326     1,266     5,394     3,605   Same Store NOI 26,521 24,677 102,502 99,385 Straight-line rent revenue adjustment (505 ) (1,283 ) (5,558 ) (5,269 ) Amortization of above- and below-market rents, net (656 ) (853 ) (2,586 ) (4,101 ) Cash NOI adjustments for unconsolidated properties (at ownership %)   (222 )   (17 )   (976 )   (380 ) Same Store Cash NOI $ 25,138   $ 22,524   $ 93,382   $ 89,635     Operating properties (2) 17 17 Rentable square feet (% owned) 6,346 6,346 ______________   (1)   From August 28, 2017 through December 31, 2017, we provided rent abatements of approximately $7.0 million to tenants at the Eldridge Properties because the properties had not been restored to pre-loss condition following Hurricane Harvey.

(2) Excludes certain operating properties that were not owned or not fully operational during the entirety of the comparable periods.

Non-GAAP Financial Measures

We compute our financial results in accordance with accounting principles generally accepted in the United States of America (GAAP). Although Funds from Operations and Funds from Operations, excluding certain items, are non-GAAP financial measures, we believe that these calculations are helpful to stockholders and potential investors and are widely recognized measures of real estate investment trust performance. We have provided a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP measure in tables included in this press release.

Funds from Operations (FFO)

Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered the presentation of operating results for real estate companies that use historical cost accounting alone to be insufficient for evaluating operating performance. FFO is a non-GAAP financial measure that is widely recognized as a measure of a REIT’s operating performance. We use FFO as defined by the National Association of Real Estate Investment Trusts (NAREIT) which is net income (loss), computed in accordance with GAAP, excluding gains (or losses) from sales of property and impairments of depreciable real estate (including impairments of investments in unconsolidated entities which resulted from measurable decreases in the fair value of the depreciable real estate held by the unconsolidated entity), plus depreciation and amortization of real estate assets, and after related adjustments for unconsolidated entities and noncontrolling interests. The determination of whether impairment charges have been incurred is based partly on anticipated operating performance and hold periods. Estimated undiscounted cash flows from a property, derived from estimated future net rental and lease revenues, net proceeds on the sale of the property, and certain other ancillary cash flows, are taken into account in determining whether an impairment charge has been incurred. While impairment charges for depreciable real estate are excluded from net income (loss) in the calculation of FFO as described above, impairments reflect a decline in the value of the applicable property that we may not recover.

We believe that the use of FFO, together with the required GAAP presentations, is helpful in understanding our operating performance because it excludes real estate-related depreciation and amortization, gains and losses from property dispositions, and impairments of depreciable real estate assets, and as a result, when compared period to period, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, which are not immediately apparent from net income. Factors that impact FFO include fixed costs, yields on cash held in accounts, income from portfolio properties and other portfolio assets, interest rates on debt financing, and operating expenses.

We also evaluate FFO, excluding certain items. The items excluded relate to certain non-operating activities or certain non-recurring activities that may create significant FFO volatility and affect the comparability of FFO across periods. We believe it is useful to evaluate FFO excluding these items because it provides useful information in analyzing comparability between reporting periods and in assessing the sustainability of our operating performance.

FFO and FFO, excluding certain items, should not be considered as alternatives to net income (loss), or as indicators of our liquidity, nor are they indicative of funds available to fund our cash needs, including our ability to make distributions. Additionally, the exclusion of impairments limits the usefulness of FFO and FFO, excluding certain items, as historical operating performance measures since an impairment charge indicates that operating performance has been permanently affected. FFO and FFO, excluding certain items, are non-GAAP measurements and should be reviewed in connection with other GAAP measurements. Our FFO and FFO, excluding certain items, as presented may not be comparable to amounts calculated by other REITs that do not define FFO in accordance with the current NAREIT definition, or interpret it differently, or that identify and exclude different items related to non-operating activities or certain non-recurring activities.

Same Store NOI and Same Store Cash NOI

Same Store NOI is equal to rental revenue, less lease termination fee income, property operating expenses (excluding tenant improvement demolition costs), real estate taxes, and property management expenses for our same store properties and is considered a non-GAAP financial measure. Same Store Cash NOI is equal to Same Store NOI less non-cash revenue items including straight-line rent adjustments and the amortization of above- and below-market rent. The same store properties include our operating office properties not held for sale and owned and operated for the entirety of both periods being compared and include our comparable ownership percentage in each period for properties in which we own an unconsolidated interest that is accounted for using the equity method. We view Same Store NOI and Same Store Cash NOI as important measures of the operating performance of our properties because they allow us to compare operating results of properties owned and operated for the entirety of both periods being compared and therefore eliminate variations caused by acquisitions or dispositions during such periods.

Same Store NOI and Same Store Cash NOI presented by us may not be comparable to Same Store NOI or Same Store Cash NOI reported by other REITs that do not define Same Store NOI or Same Store Cash NOI exactly as we do. We believe that in order to facilitate a clear understanding of our operating results, Same Store NOI and Same Store Cash NOI should be examined in conjunction with net income (loss) as presented in our consolidated financial statements and notes thereto. Same Store NOI and Same Store Cash NOI should not be considered as an indicator of our ability to make distributions, as alternatives to net income (loss) as an indication of our performance, or as a measure of cash flows or liquidity.
