Notice to Readers:

Please refer to page 3 for a discussion of important risks related to the business of Piedmont Realty TrustTM, as well as an investment in its securities, including risks that could cause actual results and events to differ materially from results and events referred to in the forward-looking information. Considering these risks, uncertainties, assumptions, and limitations, the forward-looking statements about leasing, financial operations, leasing prospects, acquisitions, dispositions, etc. contained in this quarterly supplemental information report may differ from actual results.

Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. In addition, many of the schedules herein contain rounding to the nearest thousands or millions and, therefore, the schedules may not total due to this rounding convention.

To supplement the presentation of the Company’s financial results prepared in accordance with U.S. generally accepted accounting principles (GAAP), this report contains certain financial measures that are not prepared in accordance with GAAP, including FFO, Core FFO, AFFO, Same Store NOI, Property NOI, EBITDAre and Core EBITDA. Definitions and reconciliations of these non-GAAP measures to their most comparable GAAP metrics are included beginning on page 38. Each of the non-GAAP measures included in this report has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of the Company’s results calculated in accordance with GAAP. In addition, because not all companies use identical calculations, the Company’s presentation of non-GAAP measures in this report may not be comparable to similarly titled measures disclosed by other companies, including other REITs. The Company may also change the calculation of any of the non-GAAP measures included in this report from time to time in light of its then existing operations.

Forward-Looking Statements

Certain statements contained in this press release constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Company intends for all such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act, as applicable. Such information is subject to certain known and unknown risks and uncertainties, which could cause actual results to differ materially from those anticipated. Therefore, such statements are not intended to be a guarantee of the Company`s performance in future periods. Such forward-looking statements can generally be identified by the Company's use of forward-looking terminology such as "may," "will," "expect," "intend," "anticipate," "estimate," "believe," "continue" or similar words or phrases that indicate predictions of future events or trends or that do not relate solely to historical matters. Examples of such statements in this press release include the Company's estimated range of Net Income/(Loss), Depreciation, Amortization, NAREIT FFO, Core FFO and Core FFO per diluted share for the year ending December 31, 2025. These statements are based on beliefs and assumptions of Piedmont’s management, which in turn are based on information available at the time the statements are made.

The following are some of the factors that could cause the Company's actual results and its expectations to differ materially from those described in the Company's forward-looking statements:

•Economic, regulatory, socio-economic, technological (e.g. artificial intelligence and machine learning, virtual meeting platforms, etc.), and other changes that impact the real estate market generally, the office sector or the patterns of use of commercial office space in general, or the markets where we primarily operate or have high concentrations of revenue;

•The impact of competition on our efforts to renew existing leases or re-let space on terms similar to existing leases;

•Lease terminations, lease defaults, lease contractions, or changes in the financial condition of our tenants, particularly by one of our large tenants;

•Impairment charges on our long-lived assets or goodwill resulting therefrom;

•The success of our real estate strategies and investment objectives, including our ability to implement successful redevelopment and development strategies or identify and consummate suitable acquisitions and divestitures;

•The illiquidity of real estate investments, including economic changes, such as fluctuating interest rates, costs of construction, improvements and redevelopments, and available financing, which could impact the number of buyers/sellers of our target properties, and regulatory restrictions to which real estate investment trusts ("REITs") are subject and the resulting impediment on our ability to quickly respond to adverse changes in the performance of our properties;

•The risks and uncertainties associated with our acquisition and disposition of properties, many of which risks and uncertainties may not be known at the time of acquisition or disposition;

•Development and construction delays, including the potential of supply chain disruptions, and resultant increased costs and risks;

•Future acts of terrorism, civil unrest, or armed hostilities in any of the major metropolitan areas in which we own properties;

•Risks related to the occurrence of cybersecurity incidents, including cybersecurity incidents against us or any of our properties, vendors, or tenants, or a deficiency in our identification, assessment or management of cybersecurity threats impacting our operations and the public's reaction to reported cybersecurity incidents, including the reputational impact on our business and value of our common stock;

•Costs of complying with governmental laws, regulations and policies, including environmental standards imposed on office building owners;

•Uninsured losses or losses in excess of our insurance coverage, and our inability to obtain adequate insurance coverage at a reasonable cost;

•Additional risks and costs associated with directly managing properties occupied by government tenants, such as potential changes in the political environment, a reduction in federal or state funding of our governmental tenants, government layoffs or an increased risk of default by government tenants during periods in which state or federal governments are shut down or on furlough;

•Significant price and volume fluctuations in the public markets, including on the exchange on which we listed our common stock;

•Risks associated with incurring mortgage and other indebtedness, including changing capital reserve requirements on our lenders and rising interest rates for new debt financings;

•A downgrade in our credit ratings, the credit ratings of Piedmont Operating Partnership, L.P. ("Piedmont OP") or the credit ratings of our or Piedmont OP's unsecured debt securities, which could, among other effects, trigger an increase in the stated rate of one or more of our unsecured debt instruments;

•The effect of future offerings of debt or equity securities on the value of our common stock;

•Additional risks and costs associated with adverse U.S. global and economic conditions, inflation and potential increases in the rate of inflation, including the impact of a possible recession, uncertainty and volatility in financial markets, and any changes in governmental rules, regulations, and fiscal policies;

•Uncertainties associated with environmental and regulatory matters;

•Changes in the financial condition of our tenants directly or indirectly resulting from geopolitical developments that could negatively affect important supply chains and international trade, the termination or threatened termination of existing international trade agreements, or the implementation of tariffs or retaliatory tariffs on imported or exported goods;

•The effect of any litigation to which we are, or may become, subject;

•Additional risks and costs associated with owning properties occupied by tenants in particular industries, such as oil and gas, hospitality, travel, co-working, etc., including risks of default during start-up and during economic downturns;

•Changes in tax laws impacting REITs and real estate in general, as well as our ability to continue to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), or other tax law changes which may adversely affect our stockholders;

•The future effectiveness of our internal controls and procedures; and

•Other factors, including the risk factor described in Item 1A. of our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025, as well as the risk factors discussed under Item 1A. or our Annual Report on Form 10-K for the year ended December 31, 2024.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. The Company cannot guarantee the accuracy of any such forward-looking statements contained in this press release, and the Company does not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Earnings Release

Piedmont Realty Trust Reports First Quarter 2026 Results

–Strong leasing momentum continues with over 430,000 square feet executed and cash leasing spreads of over 11%

–Generated Same Store NOI Cash Growth of over 11%

–Increases 2026 Outlook

ATLANTA, April 30, 2026 — Piedmont Realty Trust, Inc. ("Piedmont" the "Company") (NYSE:PDM), an owner of Class A office properties located primarily in major U.S. Sunbelt markets, today announced its results for the quarter ended March 31, 2026.

Commenting on operational results for the three months ended March 31, 2026, Brent Smith, Piedmont's President and Chief Executive Officer, said, "During the first quarter, we witnessed a continuation of the elevated demand that we experienced in the latter half of 2025, with tour and proposal activity at levels above our historical averages. During the quarter we executed over 430,000 square feet of leasing, and most importantly, two-thirds was related to new tenancy. The customer pipeline remains robust with over 700,000 square feet of leases either already executed or in the legal stage thus far in the second quarter. Additionally, last year’s leasing success is positively impacting our operating metrics, pushing this quarter’s same-store cash NOI growth over 11% and helping to drive a one cent increase in 2026 earnings outlook and a 1% increase in our 2026 Same Store NOI outlook. Furthermore, strong customer demand driven by the flight-to quality is giving Piedmont the opportunity to increase rents to record levels across our portfolio." Continuing, Smith added, "We were also particularly excited about several operational recognitions during the first quarter. Galleria Towers in Dallas won the CoStar Impact Award for Redevelopment of the Year in the Dallas Fort-Worth market and Piedmont, as a company, was recognized as an "Elite 5" participant in the annual Kingsley survey for the office sector. These accolades serve as further evidence that our modern, redeveloped, amenity-rich Piedmont PLACES, combined with our hospitality- infused service model, are recognized by our customers and peers as the premier office experience."

•Piedmont recognized a net loss of $12.9 million, or $0.10 per diluted share, for the first quarter of 2026, as compared to a net loss of $10.1 million, or $0.08 per diluted share, for the first quarter of 2025. Both periods reflect elevated interest expense, net of interest income, as a result of refinancing activity completed over the past several years in a higher interest rate environment. The increase in net loss recognized during the current year was primarily driven by increased depreciation expense as recently completed capital improvement projects and tenant improvements associated with new leasing activity were placed in service.

•Core FFO, which removes gain/loss on sale of real estate assets and loss on early extinguishment of debt, as well as depreciation and amortization, was $0.36 per diluted share for both the first quarter of 2026 and the first quarter of 2025. Growth in property operations during the twelve months ended March 31, 2026 was offset by the sale of 80/90 Central in Boxborough, MA and 161 Corporate Center in Irving, TX during the same period.

•During the three months ended March 31, 2026, Same Store NOI on a cash and accrual basis increased by 11.1% and 1.9% , respectively, as the commencement or burn off of abatements on new leases outweighed expiring leases.

Current Previous

(in millions, except per share data) Low High Low High

Net loss $ (45) $ (42) $ (48) $ (44)

Add:

Depreciation 181  183  181  183

Amortization 53  55  53  55

NAREIT and Core FFO applicable to common stock $ 189  $ 196  $ 186  $ 194

NAREIT and Core FFO applicable to common stock per diluted share $1.49 $1.54 $1.47 $1.53

This outlook is based on information available to management as of the date of this release and reflects management's view of current market conditions, including the following specific assumptions and projections:

6

Property Operation Assumptions:

•Executed leasing for the year of approximately 1.7 to 2.0 million square feet resulting in an increase in the anticipated year-end leased percentage for the Company's in-service portfolio to approximately 89.5% to 90.5%, exclusive of any speculative acquisition or disposition activity;

•Stabilization of the Company's out of service assets, resulting in an approximately 85-90% year-end leased percentage for the out of service portfolio and the placement of these assets back into the in-service population around the end of 2026;

•Same Store NOI increase of 4% to 7% on both a cash and accrual basis for the year, a 1% increase from our previous estimate;

Financing Assumptions:

•Interest expense (net of interest income) of approximately $125-$127 million, reflecting lower interest expense as a result of the refinancing activity completed in late 2025, partially offset by lower capitalized interest as various redevelopment projects conclude;

Other Assumptions:

•General and administrative expense of approximately $31-$33 million; and

•Weighted average shares outstanding of approximately 126-127 million.

No speculative acquisitions, dispositions, or refinancing are included in the above outlook. The Company will adjust its outlook if such transactions occur.

Note that actual results could differ materially from these estimates and individual quarters may fluctuate on both a cash basis and an accrual basis due to the timing of any future dispositions, significant lease commencements and expirations, abatement periods, repairs and maintenance expenses, capital expenditures, capital markets activities, seasonal general and administrative expenses, accrued potential performance-based compensation expense, one-time revenue or expense events, and other factors discussed under "Forward-Looking Statements" above.

(1) Bank debt covenant compliance calculations relate to the most restrictive of the specific calculations detailed in the relevant credit agreements. Please refer to such agreements for relevant defined terms.

(2) Defined as EBITDA for the trailing four quarters (including the Company's share of EBITDA from unconsolidated interests), excluding one-time or non-recurring gains or losses, less a $0.15 per square foot capital reserve, and excluding the impact of straight line rent leveling adjustments and amortization of intangibles divided by the Company's share of fixed charges, as more particularly described in the credit agreements. This definition of fixed charge coverage ratio as prescribed by our credit agreements is different from the fixed charge coverage ratio definition employed elsewhere within this report.

(3) Defined as net operating income for the trailing four quarters for unencumbered assets (including the Company's share of net operating income from partially-owned entities and subsidiaries that are deemed to be unencumbered) less a $0.15 per square foot capital reserve divided by the Company's share of interest expense associated with unsecured financings only, as more particularly described in the credit agreements.

(4)

Bond covenant compliance calculations relate to specific calculations prescribed in the relevant debt agreements. Please refer to the Indenture and the First Supplemental Indenture dated March 6, 2014, the Second Supplemental Indenture dated August 12, 2020, the Third Supplemental Indenture dated September 20, 2021, the Fourth Supplemental Indenture dated July 20, 2023, the Fifth Supplemental Indenture dated June 25, 2024, and the Sixth Supplemental Indenture dated November 20, 2025 for defined terms and detailed information about the calculations.

(5) Calculated using the sum of Core EBITDA for the trailing twelve month period and the average principal balance of debt outstanding for the trailing twelve months less the average balance of cash and restricted cash and escrows during the trailing twelve month period.

(6) Calculated as Core EBITDA divided by the sum of interest expense, principal amortization, capitalized interest and preferred dividends (none during periods presented).

The Company recorded principal amortization of $0.9 million for each of the quarters ended March 31, 2026, December 31, 2025, September 30, 2025, June 30, 2025, and March 31, 2025.

The Company recorded capitalized interest of $1.1 million for the quarter ended March 31, 2026, $1.6 million for the quarter ended December 31, 2025, $2.9 million for the quarter ended September 30, 2025, $3.2 million for the quarter ended June 30, 2025, and $3.3 million for the quarter ended March 31, 2025.

(7) Calculated as Core EBITDA divided by the sum of interest expense and capitalized interest. The Company recorded capitalized interest of $1.1 million for the quarter ended March 31, 2026, $1.6 million for the quarter ended December 31, 2025, $2.9 million for the quarter ended September 30, 2025, $3.2 million for the quarter ended June 30, 2025, and $3.3 million for the quarter ended March 31, 2025.

(1) Calculation compares the last twelve months of cash paying rents of the previous lease to the first twelve months of cash paying rents of the new lease.

(2) Calculation compares the accrual basis rents of the previous lease to the accrual basis rents of the new leases. For newly signed leases which have variations in accrual basis rents, whether because of known future expansions, contractions, lease expense recovery structure changes, or other similar reasons, the weighted average of such varying accrual basis rents is used for the calculation.

(3) Leases are excluded from the above analyses if: (1) the space has been vacant for more than one year, (2) the lease term is less than one year, (3) the lease is associated with storage space, retail space, a management office, or a percentage rent agreement, or (4) the lease is associated with a recently acquired asset for which there is less than one year of operating history.

Adjusted total per square foot per year of lease term $5.18 $6.58 $5.67 $5.22 $5.34 $5.72

(1) Excludes square feet associated with storage and license agreement transactions.

(2) Tenant improvement and leasing commission amounts presented for the year ended December 31, 2024 include a 101,500 square foot 11-year lease executed in the first quarter of 2024 with no capital outlay requirements.

(3) Tenant improvement amounts presented for the year ended December 31, 2023 were adjusted to reflect the overall concession package for the 447,000 square foot 10-year renewal with US Bancorp, executed in the fourth quarter of 2023. The renewal terms provided for zero months of rent abatement, offset by an above-market tenant improvement allowance. The amounts are presented as if the renewal had included the standard twelve months of gross rent abatement in line with market conditions and, therefore, a normalized tenant improvement allowance. This adjustment effectively lowered the total capital per square foot per year of lease term for the year ended December 31, 2023 by $0.97.

(4) The Company reports total tenant improvement amounts based on the maximum amount of committed leasing capital in the period in which the lease is executed. However, tenants do not always use the full allowance provided for in the lease, or a portion of the allowance could expire at a set date. To provide additional clarity on actual costs for completed leasing transactions, tenant improvement allowances that have expired or are no longer available to the tenant are disclosed in this section and are deducted from the capital commitments per square foot of leased space in the periods in which they expired.

Definitions

Included below are definitions of various terms used throughout this supplemental report, including definitions of certain non-GAAP financial measures and the reasons why the Company’s management believes these measures provide useful information to investors about the Company’s financial condition and results of operations. Reconciliations of any non-GAAP financial measures defined below are included beginning on page 39.

Adjusted Funds From Operations ("AFFO"): The Company calculates AFFO by starting with Core FFO and adjusting for non-incremental capital expenditures and then adding back non-cash items including: non-real estate depreciation, straight-lined rents and fair value lease adjustments, non-cash components of interest expense and compensation expense, and by making similar adjustments for joint ventures, if any. AFFO is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that AFFO is helpful to investors as a meaningful supplemental comparative performance measure of our ability to make incremental capital investments. Other REITs may not define AFFO in the same manner as the Company; therefore, the Company’s computation of AFFO may not be comparable to that of other REITs.

Annualized Lease Revenue ("ALR"): ALR is calculated by multiplying (i) current rental payments (defined as base rent plus operating expense reimbursements, if payable by the tenant on a monthly basis under the terms of a lease that has been executed, but excluding a) rental abatements and b) rental payments related to executed but not commenced leases for space that was covered by an existing lease), by (ii) 12. In instances in which contractual rents or operating expense reimbursements are collected on an annual, semi-annual, or quarterly basis, such amounts are multiplied by a factor of 1, 2, or 4, respectively, to calculate the annualized figure. For leases that have been executed but not commenced relating to unleased space, ALR is calculated by multiplying (i) the monthly base rental payment (excluding abatements) plus any operating expense reimbursements for the initial month of the lease term, by (ii) 12. Unless stated otherwise, this measure excludes revenues associated with development properties and properties taken out of service for redevelopment, if any.

Core EBITDA: The Company calculates Core EBITDA as net income/(loss) (computed in accordance with GAAP) before interest, taxes, depreciation and amortization and removing any impairment charges, gains or losses from sales of property and other significant infrequent items that create volatility within our earnings and make it difficult to determine the earnings generated by our core ongoing business. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that Core EBITDA is helpful to investors as a supplemental performance measure because it provides a metric for understanding the performance of the Company’s results from ongoing operations without taking into account the effects of non-cash expenses (such as depreciation and amortization), as well as items that are not part of normal day-to-day operations of the Company’s business. Other REITs may not define Core EBITDA in the same manner as the Company; therefore, the Company’s computation of Core EBITDA may not be comparable to that of other REITs.

Core Funds From Operations ("Core FFO"): The Company calculates Core FFO by starting with FFO, as defined by NAREIT, and adjusting for gains or losses on the extinguishment of swaps and/or debt and any significant non-recurring items. Core FFO is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that Core FFO is helpful to investors as a supplemental performance measure because it excludes the effects of certain infrequent or non-recurring items which can create significant earnings volatility, but which do not directly relate to the Company’s core business operations. As a result, the Company believes that Core FFO can help facilitate comparisons of operating performance between periods and provides a more meaningful predictor of future earnings potential. Other REITs may not define Core FFO in the same manner as the Company; therefore, the Company’s computation of Core FFO may not be comparable to that of other REITs.

EBITDA: EBITDA is defined as net income/(loss) before interest, taxes, depreciation and amortization.

EBITDAre: The Company calculates EBITDAre in accordance with the current National Association of Real Estate Investment Trusts (“NAREIT”) definition. NAREIT currently defines EBITDAre as net income/(loss) (computed in accordance with GAAP) adjusted for gains or losses from sales of property, impairment charges, depreciation on real estate assets, amortization on real estate assets, interest expense and taxes, along with the same adjustments for joint ventures. Some of the adjustments mentioned can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. EBITDAre is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that EBITDAre is helpful to investors as a supplemental performance measure because it provides a metric for understanding the Company’s results from ongoing operations without taking into account the effects of non-cash expenses (such as depreciation and amortization) and capitalization and capital structure expenses (such as interest expense and taxes). The Company also believes that EBITDAre can help facilitate comparisons of operating performance between periods and with other REITs. However, other REITs may not define EBITDAre in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than the Company; therefore, the Company’s computation of EBITDAre may not be comparable to that of such other REITs.

Funds From Operations ("FFO"): The Company calculates FFO in accordance with the current National Association of Real Estate Investment Trusts (“NAREIT”) definition. NAREIT currently defines FFO as net income/(loss) (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets, goodwill, and investment in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity, along with appropriate adjustments to those reconciling items for joint ventures, if any. These adjustments can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. FFO is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that FFO is helpful to investors as a supplemental performance measure because it excludes the effects of depreciation, amortization and gains or losses from sales of real estate, all of which are based on historical costs, which implicitly assumes that the value of real estate diminishes predictably over time. The Company also believes that FFO can help facilitate comparisons of operating performance between periods and with other REITs. However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than the Company; therefore, the Company’s computation of FFO may not be comparable to that of such other REITs.

Incremental Capital Expenditures: Incremental Capital Expenditures are defined as capital expenditures of a non-recurring nature that incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives ("Leasing Costs") incurred to lease space that was vacant at acquisition, Leasing Costs for spaces vacant for greater than one year, Leasing Costs for spaces at newly acquired properties for which in-place leases expire shortly after acquisition, improvements associated with the expansion of a building, renovations that change the underlying classification of a building, and deferred building maintenance capital identified at and completed shortly after acquisition are included in this measure.

Non-Incremental Capital Expenditures: Non-Incremental Capital Expenditures are defined as capital expenditures of a recurring nature related to tenant improvements and leasing commissions that do not incrementally enhance the underlying assets' income generating capacity. We exclude first generation tenant improvements and leasing commissions from this measure, in addition to other capital expenditures that qualify as Incremental Capital Expenditures, as defined above.

Property Net Operating Income ("Property NOI"): The Company calculates Property NOI by starting with Core EBITDA and adjusting for general and administrative expense, income associated with property management performed by Piedmont for other organizations and other income or expense items for the Company, such as interest income from loan investments or costs from the pursuit of non-consummated transactions. The Company may present this measure on an accrual basis or a cash basis. When presented on a cash basis, the effects of non-cash general reserve for uncollectible accounts, straight-lined rents and fair value lease revenue are also eliminated. Property NOI is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that Property NOI is helpful to investors as a supplemental comparative performance measure of income generated by its properties alone without the administrative overhead of the Company. Other REITs may not define Property NOI in the same manner as the Company; therefore, the Company’s computation of Property NOI may not be comparable to that of other REITs.

Same Store Net Operating Income ("Same Store NOI"): The Company calculates Same Store NOI as Property NOI attributable to the properties for which the following criteria were met during the entire span of the current and prior year reporting periods: (i) they were owned, (ii) they were not under development / redevelopment, and (iii) none of the operating expenses for which were capitalized. Same Store NOI also excludes amounts attributable to land assets. The Company may present this measure on an accrual basis or a cash basis. Same Store NOI is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of the Company’s operating performance. The Company believes that Same Store NOI is helpful to investors as a supplemental comparative performance measure of the income generated from the same group of properties from one period to the next. Other REITs may not define Same Store NOI in the same manner as the Company; therefore, the Company’s computation of Same Store NOI may not be comparable to that of other REITs.

Same Store Properties: Same Store Properties is defined as those properties for which the following criteria were met during the entire span of the current and prior year reporting periods: (i) they were owned, (ii) they were not under development / redevelopment, and (iii) none of the operating expenses for which were capitalized. Same Store Properties excludes land assets.

Total Gross Assets: Total Gross Assets is defined as total assets with the add-back of accumulated depreciation and accumulated amortization related to real estate assets and accumulated amortization related to deferred lease costs.

Total Gross Real Estate Assets: Total Gross Real Estate Assets is defined as total real estate assets with the add-back of accumulated depreciation and accumulated amortization related to real estate assets.
