CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
Certain statements contained in this Form 10-Q may constitute forward-looking statements within the meaning of the federal securities laws. In addition, Piedmont Office Realty Trust, Inc. ("Piedmont," "we," "our," or "us"), or its executive officers on Piedmont’s behalf, may from time to time make forward-looking statements in reports and other documents Piedmont files with the Securities and Exchange Commission or in connection with other written or oral statements made to the press, potential investors, or others. Statements regarding future events and developments and Piedmont’s future performance, as well as management’s expectations, beliefs, plans, estimates, or projections relating to the future, are forward-looking statements. Forward-looking statements include statements preceded by, followed by, or that include the words “may,” “will,” “expect,” “intend,” “anticipate,” “estimate,” “believe,” “continue,” or other similar words. Examples of such statements in this report include descriptions of our real estate, financings, and operating objectives; discussions regarding future dividends and share repurchases; discussions regarding the potential uses of capital and means to secure additional sources of capital; and discussions regarding the potential impact of economic conditions on our real estate and lease portfolio, among others.

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. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding the demand for office space in the markets in which Piedmont operates, competitive conditions, and general economic conditions. These assumptions could prove inaccurate. The forward-looking statements also involve risks and uncertainties, which could cause actual results to differ materially from those contained in any forward-looking statement. Many of these factors are beyond Piedmont’s ability to control or predict. Such factors include, but are not limited to, the following:

Economic, regulatory, socio-economic changes, and/or technology changes (including accounting standards) that impact the real estate market generally, or that could affect patterns of use of commercial office space;
The impact of competition on our efforts to renew existing leases or re-let space on terms similar to existing leases;
Changes in the economies and other conditions affecting the office sector in general and specifically the seven markets in which we primarily operate where we have high concentrations of our Annualized Lease Revenue (see definition below);
Lease terminations, lease defaults, or changes in the financial condition of our tenants, particularly by one of our large lead tenants;
Adverse market and economic conditions, including any resulting impairment charges on both our long-lived assets or goodwill resulting therefrom;
The success of our real estate strategies and investment objectives, including our ability to identify and consummate suitable acquisitions and divestitures;
The illiquidity of real estate investments, including 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 and resultant increased costs and risks;
Our real estate development strategies may not be successful;
Future acts of terrorism, civil unrest, or armed hostilities in any of the major metropolitan areas in which we own properties, or future cybersecurity attacks against any of our tenants;
Risks related to the occurrence of cyber incidents, or a deficiency in our cybersecurity, which could negatively impact our business by causing a disruption to our operations, a compromise or corruption of our confidential information, and/or damage to our business relationships;
Costs of complying with governmental laws and regulations;
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, including 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 which we listed our common stock;
Changes in interest rates and changes in the method pursuant to which the LIBOR rates are determined and the planned phasing out of USD LIBOR after June 2023;
High interest rates which could affect our ability to finance or refinance properties;
The effect of future offerings of debt or equity securities or changes in market interest rates on the value of our common stock;

Table of Contents
Uncertainties associated with environmental and other regulatory matters;
Potential changes in the political environment and reduction in federal and/or state funding of our governmental tenants;
Changes in the financial condition of our tenants directly or indirectly resulting from geopolitical developments that could negatively affect 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;
Actual or threatened public health epidemics or outbreaks, such as the ongoing COVID-19 pandemic, and governmental and private measures taken to combat such health crises, which may affect our personnel, tenants, tenants' operations and ability to pay lease obligations, demand for office space, and the costs of operating our assets;
The adequacy of our general reserve related to tenant lease-related assets established as a result of the COVID-19 pandemic, as well as the impact of any increase in this reserve or the establishment of any other reserve in the future; and

Management believes these forward-looking statements are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations.

Information Regarding Disclosures Presented

Annualized Lease Revenue ("ALR"), a non-GAAP measure, 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.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2021
(Unaudited)

1.    Organization
Piedmont Office Realty Trust, Inc. (“Piedmont”) (NYSE: PDM) is a Maryland corporation that operates in a manner so as to qualify as a real estate investment trust (“REIT”) for federal income tax purposes and engages in the ownership, management, development, redevelopment, and operation of high-quality, Class A office properties located primarily in select sub-markets within seven major Eastern U.S. office markets, with a majority of its revenue being generated from the Sunbelt. Piedmont was incorporated in 1997 and commenced operations in 1998. Piedmont conducts business through its wholly-owned subsidiary, Piedmont Operating Partnership, L.P. (“Piedmont OP”), a Delaware limited partnership. Piedmont OP owns properties directly, through wholly-owned subsidiaries, and through various joint ventures which it controls. References to Piedmont herein shall include Piedmont and all of its subsidiaries, including Piedmont OP and its subsidiaries and joint ventures.

As of September 30, 2021, Piedmont owned 54 in-service office properties and one redevelopment asset in select sub-markets located within the following seven major U.S. office markets: Dallas, Atlanta, Washington, D.C., Minneapolis, Boston, Orlando, and New York. As of September 30, 2021, Piedmont's 54 in-service office properties comprised approximately 16.4 million square feet (unaudited) of primarily Class A commercial office space and were approximately 86% leased.

2.    Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation

The consolidated financial statements of Piedmont have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”), including the instructions to Form 10-Q and Article 10 of Regulation S-X, and do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for such periods. Results for these interim periods are not necessarily indicative of a full year’s results.

Piedmont’s consolidated financial statements include the accounts of Piedmont, Piedmont’s wholly-owned subsidiaries, any variable interest entity ("VIE") of which Piedmont or any of its wholly-owned subsidiaries is considered to have the power to direct the activities of the entity and the obligation to absorb losses/right to receive benefits, or any entity in which Piedmont or any of its wholly-owned subsidiaries owns a controlling interest. In determining whether Piedmont or Piedmont OP has a controlling interest, the following factors, among others, are considered: equity ownership, voting rights, protective rights of investors, and participatory rights of investors. For further information, refer to the financial statements and footnotes included in Piedmont’s Annual Report on Form 10-K for the year ended December 31, 2020.

All intercompany balances and transactions have been eliminated upon consolidation.

Further, Piedmont has formed special purpose entities to acquire and hold real estate. Each special purpose entity is a separate legal entity. Consequently, the assets of these special purpose entities are not available to all creditors of Piedmont. The assets owned by these special purpose entities are being reported on a consolidated basis with Piedmont’s assets for financial reporting purposes only.

Use of Estimates

The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and notes. The most significant of these estimates include the underlying cash flows and holding periods used in assessing impairment, judgements regarding the recoverability of goodwill, and the assessment of the collectibility of receivables. While Piedmont has made, what it believes to be, appropriate accounting estimates based on the facts and circumstances available as of the reporting date, actual results could materially differ from those estimates.

Table of Contents
Income Taxes

Piedmont has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, and has operated as such, beginning with its taxable year ended December 31, 1998. To qualify as a REIT, Piedmont must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income. As a REIT, Piedmont is generally not subject to federal income taxes, subject to fulfilling, among other things, its taxable income distribution requirement. Piedmont is subject to certain taxes related to the operations of properties in certain locations, as well as operations conducted by its taxable REIT subsidiary which have been provided for in the financial statements.

Operating Leases

Piedmont recognized the following fixed and variable lease payments, which together comprised rental and tenant reimbursement revenue in the accompanying consolidated statements of income for the three and nine months ended September 30, 2021 and 2020, respectively, as follows (in thousands):

Total Rental and Tenant Reimbursement Revenue
$127,427 $128,280 $380,306 $391,681 

Operating leases where Piedmont is the lessee relate primarily to office space in buildings owned by third parties. For the three and nine months ended September 30, 2021 and 2020, Piedmont recognized approximately $20,000 and $60,000, respectively, of operating lease costs related to these office space leases. As of September 30, 2021, the remaining lease term of Piedmont's right of use asset is approximately one year, and the discount rate is 1.06%.

Reclassifications

Certain prior period amounts presented in the accompanying consolidated balance sheets have been reclassified as of December 31, 2020 to conform to the current period financial statement presentation. Such amounts relate to the 225 and 235 Presidential Way buildings, which were classified as held for sale as of June 30, 2021. (see Note 7).

3.    Debt

During the nine months ended September 30, 2021, Piedmont issued, through Piedmont OP, $300 million in aggregate principal amount of 2.75% Senior Notes due 2032 (the “$300 Million Unsecured Senior Notes due 2032”), which mature on April 1, 2032. Upon issuance of the $300 Million Unsecured Senior Notes due 2032, Piedmont OP received proceeds of approximately $298.5 million, reflecting a discount of approximately $1.5 million which will be amortized as interest expense using the effective interest method over the 10-year and 6-month term of the $300 Million Unsecured Senior Notes due 2032. In addition, in conjunction with the issuance, Piedmont settled one forward starting interest rate swap, consisting of a notional amount of $50 million. The settlement of the swap resulted in a gain of approximately $0.6 million that was recorded as accumulated other comprehensive income and will be amortized as a decrease in interest expense over the 10-year and 6-month term of the $300 Million Unsecured Senior Notes due 2032. See Note 4 for further detail. The proceeds from the $300 Million Unsecured Senior Notes due 2032 were used to fully repay, without penalty, the Amended and Restated $300 Million Unsecured 2011 Term Loan that was scheduled to mature in November 2021.

Interest on the $300 Million Unsecured Senior Notes due 2032 is payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2022. The $300 Million Unsecured Senior Notes due 2032 are fully and unconditionally guaranteed on a senior unsecured basis by Piedmont. Piedmont OP may, at its option, redeem the $300 Million Unsecured Senior Notes due 2032, in whole or in part, prior to January 1, 2032, at a redemption price equal to the greater of (i) 100% of the principal amount of the $300 Million Unsecured Senior Notes due 2032 to be redeemed and (ii) a “make-whole” amount, plus any unpaid accrued interest. In addition, at any time on or after January 1, 2032, Piedmont OP may, at its option, redeem the $300 Million Unsecured Senior Notes due 2032, in whole or in part, at a redemption price equal to 100% of the principal amount of the $300 Million Unsecured Senior Notes due 2032 to be redeemed plus unpaid accrued interest. The $300 Million Unsecured Senior Notes due 2032 are subject to certain typical covenants that, subject to certain exceptions: (a) limit the ability of Piedmont and Piedmont OP to, among other things, incur additional secured and unsecured indebtedness; (b) limit the ability of Piedmont and Piedmont OP to merge, consolidate, sell, lease or otherwise dispose of their properties and assets substantially

as an entirety; and (c) require Piedmont to maintain a pool of unencumbered assets. The $300 Million Unsecured Senior Notes due 2032 are also subject to customary events of default which, if any of them occurs, would permit or require the principal of and accrued interest on the $300 Million Unsecured Senior Notes due 2032 to become or to be declared due and payable.

Table of Contents
Piedmont made interest payments on all debt facilities, including interest rate swap cash settlements, of approximately $16.2 million and $12.8 million for the three months ended September 30, 2021 and 2020, respectively, and approximately $41.5 million and $41.8 million for the nine months ended September 30, 2021 and 2020, respectively. Also, Piedmont capitalized interest of approximately $1.0 million and $0.2 million for the three months ended September 30, 2021 and 2020, respectively, and approximately $2.7 million and $0.6 million for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, Piedmont believes it was in compliance with all financial covenants associated with its debt instruments.

See Note 5 for a description of Piedmont’s estimated fair value of debt as of September 30, 2021.

4.    Derivative Instruments
Risk Management Objective of Using Derivatives

In addition to operational risks which arise in the normal course of business, Piedmont is exposed to economic risks such as interest rate, liquidity, and credit risk. In certain situations, Piedmont has entered into derivative financial instruments such as interest rate swap agreements and other similar agreements to manage interest rate risk exposure arising from current or future variable rate debt transactions. Interest rate swap agreements involve the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Piedmont’s objective in using interest rate derivatives is to add stability to interest expense and to manage its exposure to interest rate movements.

Cash Flow Hedges of Interest Rate Risk

Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for Piedmont making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. During the three months ended September 30, 2021, Piedmont entered into, and subsequently settled, one forward starting interest rate swap agreement with a notional value of $50 million to hedge the risk of changes in the interest-related cash flows associated with the issuance of the $300 Million Unsecured Senior Notes due 2032 (see Note 3). The settlement resulted in a gain of approximately $0.6 million, which was recorded as accumulated OCI and is being amortized as an offset to interest expense over the following ten years.

The maximum length of time over which Piedmont is hedging its exposure to the variability in future cash flows for forecasted transactions is 42 months. A detail of Piedmont’s interest rate derivatives outstanding as of September 30, 2021 is as follows:

Piedmont estimates that approximately $2.9 million will be reclassified from OCI as an increase in interest expense over the next twelve months. Piedmont recognized no hedge ineffectiveness on its cash flow hedges during the three and nine months ended September 30, 2021 and 2020, respectively.

Additionally, see Note 5 for fair value disclosures of Piedmont's derivative instruments.

Credit-risk-related Contingent Features

Piedmont has agreements with its derivative counterparties that contain a provision whereby if Piedmont defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Piedmont could also be declared in default on its derivative obligations. If Piedmont were to breach any of the contractual provisions of the derivative contracts, it could be required to settle its liability obligations under the agreements at their termination value of the estimated fair values plus accrued interest, or approximately $6.8 million as of September 30, 2021. Additionally, Piedmont has rights of set-off under certain of its derivative agreements related to potential termination fees and amounts payable under the agreements, if a termination were to occur.

5.    Fair Value Measurement of Financial Instruments
Piedmont considers its cash and cash equivalents, tenant receivables, notes receivable, restricted cash and escrows, accounts payable and accrued expenses, interest rate swap agreements, and debt to meet the definition of financial instruments. The following table sets forth the carrying and estimated fair value for each of Piedmont’s financial instruments, as well as its level within the GAAP fair value hierarchy, as of September 30, 2021 and December 31, 2020, respectively (in thousands):

Piedmont's notes receivable and debt were carried at book value as of September 30, 2021 and December 31, 2020; however, Piedmont's estimate of the fair value of each of these financial instruments as of each period end is disclosed in the table above.
16

Table of Contents
Piedmont issued notes receivable in conjunction with the sale of properties to an unrelated third-party buyer in October 2020. As the facts and circumstances as of December 31, 2020 were substantially unchanged since the issuance of the notes receivable in October 2020, Piedmont determined that the book value of the notes approximated their estimated fair value as of December 31, 2020. Piedmont uses widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of its notes receivables and debt, including the period to maturity of each note receivable and debt facility, and uses observable market-based inputs for similar loan and debt facilities which have transacted recently in the market. Scaling adjustments are made to these inputs to make them applicable to the remaining life of Piedmont's notes receivables and outstanding debt. Consequently, the estimated fair values of the notes receivable as of September 30, 2021 and debt as of both December 31, 2020 and September 30, 2021 are considered to be based on significant other observable inputs (Level 2). Piedmont has not changed its valuation technique for estimating the fair value of its notes receivable or debt.

Piedmont’s interest rate swap agreements presented above, and as further discussed in Note 4, are classified as “Interest rate swap” liabilities in the accompanying consolidated balance sheets and were carried at estimated fair value as of September 30, 2021 and December 31, 2020. The valuation of these derivative instruments was determined using widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of the derivatives, including the period to maturity of each instrument, and uses observable market-based inputs, including interest rate curves and implied volatilities. Therefore, the estimated fair values determined are considered to be based on significant other observable inputs (Level 2). In addition, Piedmont considered both its own and the respective counterparties’ risk of nonperformance in determining the estimated fair value of its derivative financial instruments by estimating the current and potential future exposure under the derivative financial instruments that both Piedmont and the counterparties were at risk for as of the valuation date. The credit risk of Piedmont and its counterparties was factored into the calculation of the estimated fair value of the interest rate swaps; however, as of September 30, 2021 and December 31, 2020, this credit valuation adjustment did not comprise a material portion of the estimated fair value. Therefore, Piedmont believes that any unobservable inputs used to determine the estimated fair values of its derivative financial instruments are not significant to the fair value measurements in their entirety, and does not consider any of its derivative financial instruments to be Level 3 liabilities.

6.    Commitments and Contingencies

Commitments Under Existing Lease Agreements

As a recurring part of its business, Piedmont is typically required under its executed lease agreements to fund tenant improvements, leasing commissions, and building improvements. In addition, certain agreements contain provisions that require Piedmont to issue corporate or property guarantees to provide funding for capital improvements or other financial obligations. As of September 30, 2021, Piedmont had one individually significant unrecorded tenant allowance commitment of approximately $21.8 million for the approximately 20-year, 520,000 square foot renewal and expansion on behalf of Piedmont's largest tenant, the State of New York at the 60 Broad Street building in New York City. This commitment will be accrued and capitalized as the related expenditures are incurred.

Contingencies Related to Tenant Audits/Disputes

Certain lease agreements include provisions that grant tenants the right to engage independent auditors to audit their annual operating expense reconciliations. Such audits may result in different interpretations of language in the lease agreements from that made by Piedmont, which could result in requests for refunds of previously recognized tenant reimbursement revenues, resulting in financial loss to Piedmont. There were no reductions in rental and reimbursement revenues related to such tenant audits/disputes during the three or nine months ended September 30, 2021 or 2020.

Contingencies Related to the COVID-19 Pandemic

The long-term impacts of the COVID-19 pandemic on our tenants and the global economy remain unclear and any adverse affect on certain of Piedmont's tenant's operating results or future leasing decisions could, in turn, adversely impact Piedmont's business, financial condition and results of operations.

7.    Assets Held for Sale

Piedmont is under a binding contract to sell the 225 and 235 Presidential Way assets in Woburn, Massachusetts for $129.0 million, or $293 per square foot. Consequently, the assets, which are assigned to the Boston geographic reportable segment, met the criteria for held for sale classification and the assets of these properties as of September 30, 2021 and December 31, 2020 are presented as held for sale for comparability in the accompanying consolidated balance sheets. The sale of the properties is expected to close early in 2022, subject to customary closing conditions.

8.    Stock Based Compensation
The Compensation Committee of Piedmont's Board of Directors has typically granted deferred stock award units to all of Piedmont's employees based upon the previous year's financial results measured against various board approved performance metrics. Most employee awards vest ratably over three years. In addition, Piedmont's independent directors receive an annual grant of deferred stock award units for services rendered and such awards vest over a one year service period.

Certain management employees' long-term equity incentive program is split equally between the deferred stock award units described above and a multi-year performance share program whereby actual awards are contingent upon Piedmont's total stockholder return ("TSR") performance relative to the TSR of a peer group of office REITs. The target incentives for these certain employees, as well as the peer group to be used for comparative purposes, are predetermined by the Board of Directors, advised by an outside compensation consultant. Any shares earned are awarded at the end of the multi-year performance period and vest upon award. The grant date fair value of the multi-year performance share awards is estimated using the Monte Carlo valuation method.

10.    Earnings Per Share

There are no adjustments to “Net income applicable to Piedmont” for the diluted earnings per share computations.

Net income per share-basic is calculated as net income available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income per share-diluted is calculated as net income available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including unvested deferred stock awards. Diluted weighted average number of common shares reflects the potential dilution under the treasury stock method that would occur if the remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Unvested and potential stock awards which are determined to be anti-dilutive are not included in the calculation of diluted weighted average common shares. For the three months ended September 30, 2021 and 2020, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of approximately 145,222 and 310,425, respectively, and for the nine months ended September 30, 2021 and 2020, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of 313,140 and 262,165, respectively.

11.    Segment Information

Piedmont's President and Chief Executive Officer has been identified as Piedmont's chief operating decision maker ("CODM"), as defined by GAAP. The CODM evaluates Piedmont's portfolio and assesses the ongoing operations and performance of its properties utilizing the following geographic segments: Dallas, Atlanta, Washington, D.C., Minneapolis, Boston, Orlando, and New York. These operating segments are also Piedmont’s reportable segments. As of September 30, 2021, Piedmont also owned two properties in Houston and one property in Chicago that do not meet the definition of an operating or reportable segment as the CODM does not regularly review these properties for purposes of allocating resources or assessing performance. Further, Piedmont does not maintain a significant presence or anticipate further investment in these markets. These three properties are included in "Corporate and other" below. During the periods presented, there have been no material inter segment transactions. The accounting policies of the reportable segments are the same as Piedmont's accounting policies.

Accrual-based net operating income ("NOI") by geographic segment is the primary performance measure reviewed by Piedmont's CODM to assess operating performance and consists only of revenues and expenses directly related to real estate rental operations. NOI is calculated by deducting property operating costs from lease revenues and other property related income. NOI reflects property acquisitions and dispositions, occupancy levels, rental rate increases or decreases, and the recoverability of operating expenses. Piedmont's calculation of NOI may not be directly comparable to similarly titled measures calculated by other REITs.

Asset value information and capital expenditures by segment are not reported because the CODM does not use these measures to assess performance.

The following table presents accrual-based lease revenue and other property related income included in NOI by geographic reportable segment (in thousands):

ITEM 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis should be read in conjunction with the accompanying consolidated financial statements and notes thereto of Piedmont Office Realty Trust, Inc. (“Piedmont,” "we," "our," or "us"). See also “Cautionary Note Regarding Forward-Looking Statements” preceding Part I, as well as the consolidated financial statements and accompanying notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Given our low-leverage operating model of long-term leases targeted toward creditworthy tenants, the COVID-19 pandemic has not materially impacted our financial condition, overall liquidity position and outlook, or caused material impairments in our portfolio of operating properties; however, the pandemic-related slowdown of leasing activity during 2020 and the first half of 2021 has moderated earnings growth and negatively impacted our occupancy levels and rental rate growth. The pandemic has had an ongoing impact on a few of our small, primarily retail, tenants and the long-term repercussions on our tenant's operations, future leasing decisions, and the global economy remains unclear.

Liquidity and Capital Resources

We intend to use cash on hand, cash flows generated from the operation of our properties, net proceeds from the disposition of select properties, and proceeds from our $500 Million Unsecured 2018 Line of Credit as our primary sources of immediate liquidity. We have $202 million of capacity on our $500 million line of credit available as of the date of this filing. When necessary, we may seek other new secured or unsecured borrowings from third party lenders or issue securities as additional sources of capital. The nature and timing of these additional sources of capital will be highly dependent on market conditions.

Our most consistent use of capital has historically been, and we believe will continue to be, to fund capital expenditures for our existing portfolio of properties. During the nine months ended September 30, 2021 and 2020 we incurred the following types of capital expenditures (in thousands):
Nine Months Ended
September 30, 2021September 30, 2020
Capital expenditures for redevelopment/renovations$36,382 $27,462 
Other capital expenditures, including building and tenant improvements47,095 52,545 
Total capital expenditures (1)
$83,477 $80,007 

(1)Of the total amounts paid, approximately $4.5 million and $1.1 million relates to soft costs such as capitalized interest, payroll, and general and administrative expenses for the nine months ended September 30, 2021 and 2020, respectively.

"Capital expenditures for redevelopment/renovations" during both the nine months ended September 30, 2021 and 2020 related to building upgrades, primarily to the lobbies and the addition of tenant amenities at our 60 Broad Street building in New York City; our 200 South Orange Avenue building in Orlando, Florida; our Galleria buildings in Atlanta, Georgia; and our 25 Burlington Mall Road building in Boston, Massachusetts.

"Other capital expenditures, including building and tenant improvements" includes all other capital expenditures during the period and is typically comprised of tenant and building improvements necessary to lease, maintain, or provide enhancements to our existing portfolio of office properties.

Given that our operating model frequently results in leases for large blocks of space to creditworthy tenants, our leasing success can result in capital outlays which can vary significantly from one reporting period to another based upon the specific leases executed. For leases executed during the nine months ended September 30, 2021, we committed to spend approximately $3.95 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as compared to $5.90 (net of expired lease commitments) for the nine months ended September 30, 2020. As of September 30, 2021, we had one individually significant unrecorded tenant allowance commitment outstanding of approximately $21.8 million related to the State of New York's lease at our 60 Broad Street building.

In addition to the amounts that we have already committed to as a part of executed leases, we also anticipate continuing to incur similar market-based tenant improvement allowances and leasing commissions in conjunction with procuring future leases for our existing portfolio of properties. Both the timing and magnitude of expenditures related to future leasing activity can vary due to a number of factors and are highly dependent on the competitive market conditions of the particular office market at the time a lease is being negotiated.

There are other uses of capital that may arise as part of our typical operations. Subject to the identification and availability of attractive investment opportunities and our ability to consummate such acquisitions on satisfactory terms, acquiring new assets consistent with our investment strategy could also be a significant use of capital. We may also use capital resources to repurchase additional shares of our common stock under our stock repurchase program when we believe the stock is trading disparately from our peers and at a significant discount to net asset value. As of September 30, 2021, we had approximately $169.3 million of board-authorized capacity remaining for future stock repurchases. Finally, with no other immediate maturities, we currently plan to renew our revolving line of credit in 2022. We may also use capital to repay other debt obligations when we deem it prudent to refinance various obligations.

The amount and form of payment (cash or stock issuance) of future dividends to be paid to our stockholders will continue to be largely dependent upon (i) the amount of cash generated from our operating activities; (ii) our expectations of future cash flows; (iii) our determination of near-term cash needs for debt repayments, development projects, and selective acquisitions of new properties; (iv) the timing of significant expenditures for tenant improvements, leasing commissions, building redevelopment projects, and general property capital improvements; (v) long-term dividend payout ratios for comparable companies; (vi) our ability to continue to access additional sources of capital, including potential sales of our properties; and (vii) the amount required to be distributed to maintain our status as a REIT. With the fluctuating nature of cash flows and expenditures, we may periodically borrow funds on a short-term basis to cover timing differences in cash receipts and cash disbursements.

Results of Operations

Overview

Net income applicable to common stockholders for the three months ended September 30, 2021 was $11.3 million, or $0.09 per diluted share, as compared with net income applicable to common stockholders of $8.9 million, or $0.07 per diluted share, for the three months ended September 30, 2020. The increase recognized during the current quarter is primarily attributable to rising rental rates, decreased operating expenses, particularly related to our landlord's portion of real estate taxes, as well as the expiration of operating expense recovery abatements on certain leases. These improvements were partially offset by a 0.9% reduction in our overall leased percentage on a year-to-date basis as a result of reduced new leasing activity in 2020 and the first half of 2021 due to the COVID-19 pandemic.

Revenue

Rental and tenant reimbursement revenue decreased approximately $0.9 million for the three months ended September 30, 2021, as compared to the same period in the prior year, primarily reflecting the impacts of lower overall occupancy due to slow leasing activity in 2020 and the first half of 2021 due to the COVID-19 pandemic and disposition activity that occurred during 2020, partially offset by the growth in rental rates and higher reimbursement income on certain large leases in 2021 due to the expiration of operating expense abatements.

Other property related income increased approximately $0.3 million for the three months ended September 30, 2021 as compared to the same period in the prior year primarily due an increase in transient parking utilization at our buildings which was lower during 2020 as a result of the COVID-19 pandemic.

Expense

Property operating costs decreased approximately $1.5 million for the three months ended September 30, 2021, as compared to the same period in the prior year, reflecting lower real estate taxes at certain properties, as well as disposition activity that occurred during 2020.

Depreciation expense increased approximately $2.2 million for the three months ended September 30, 2021 as compared to the same period in the prior year. Approximately $4.4 million of the increase was due to depreciation on additional building and tenant improvements placed in service subsequent to July 1, 2020 at our existing properties. This increase was partially offset by disposition activity subsequent to July 1, 2020, as well as the cessation of depreciation on the 225 and 235 Presidential Way assets as a result of classifying these assets as held for sale in May 2021.

Amortization expense decreased approximately $2.6 million for the three months ended September 30, 2021 as compared to the same period in the prior year. The decrease is primarily due to certain lease intangible assets at our existing properties becoming fully amortized subsequent to July 1, 2020.

General and administrative expense increased approximately $1.4 million for the three months ended September 30, 2021 as
25

Table of Contents
compared to the same period in the prior year, primarily reflecting reduced accruals for potential performance based compensation during the three months ended September 30, 2020 as a result of the COVID-19 pandemic.

Other Income (Expense)

Interest expense decreased approximately $0.3 million for the three months ended September 30, 2021 as compared to the same period in the prior year primarily as a result of the repayment of a $35 million mortgage using funding from our lower-rate revolving line of credit in June 2021.

Other income increased approximately $2.0 million for the three months ended September 30, 2021 as compared to the same period in the prior year. The variance is attributable to interest income recognized on notes receivable due from the purchaser of our New Jersey Portfolio in October 2020. The notes receivable mature in October 2023 and are secured by the two Bridgewater Crossing properties, sold in 2020.

Loss on sale of real estate assets during the three months ended September 30, 2020 represents a true-up adjustment to the significant gain recognized on the sale of the 1901 Market Street building during the second quarter of 2020.

Revenue

Rental and tenant reimbursement revenue decreased approximately $11.4 million for the nine months ended September 30, 2021 as compared to the same period in the prior year, primarily reflecting lower overall occupancy in 2021 and the impact of net disposition activity that occurred during 2020, partially offset by higher reimbursement income due to the expiration of operating expense abatements on certain large leases in 2021.

Other property related income decreased approximately $1.4 million for the nine months ended September 30, 2021 as compared to the same period in the prior year primarily due to lower transient parking utilization at our buildings as result of the COVID-19 pandemic.

Expense

Property operating costs decreased approximately $4.8 million for the nine months ended September 30, 2021 as compared to the same period in the prior year. The variance was primarily due to net disposition activity that occurred during 2020 as well as lower real estate taxes in certain jurisdictions and lower operating expenses such as janitorial and utilities due to lower tenant utilization at the properties in 2021 due to the COVID-19 pandemic.

Depreciation expense increased approximately $5.3 million for the nine months ended September 30, 2021 as compared to the same period in the prior year. The increase was primarily due to additional building and tenant improvements placed in service subsequent to January 1, 2020, partially offset by a net decrease in depreciation associated with net disposition activity subsequent to January 1, 2020, as well as the cessation of depreciation on the 225 and 235 Presidential Way assets as a result of classifying these assets as held for sale in May 2021.

Amortization expense decreased approximately $7.0 million for the nine months ended September 30, 2021 as compared to the same period in the prior year. Amortization expense decreased primarily due to certain lease intangible assets at our existing properties becoming fully amortized subsequent to January 1, 2020.

Table of Contents
General and administrative expenses increased approximately $2.3 million for the nine months ended September 30, 2021 as compared to the same period in the prior year, primarily reflecting reduced accruals during the nine months ended September 30, 2020 for potential performance based compensation tied to the sharp decline in leasing activity and stock performance as a result of the COVID-19 pandemic.

Other Income (Expense)

Interest expense decreased approximately $4.5 million for the nine months ended September 30, 2021 as compared to the same period in the prior year primarily as a result of the repayment of a $160 million mortgage in conjunction with the sale of the 1901 Market Street building in June 2020. An increase in capitalized interest for redevelopment projects at 60 Broad Street, 200 South Orange Avenue, 25 Burlington Mall Road, and Galleria Atlanta during the nine months ended September 30, 2021 also contributed to the decrease in interest expense.

Other income increased approximately $6.5 million for the nine months ended September 30, 2021 as compared to the same period in the prior year. The variance is attributable to interest income recognized on notes receivable due from the purchaser of our New Jersey Portfolio in October 2020. The notes receivable mature in October 2023 and are secured by the two Bridgewater Crossing properties, sold in 2020.

The loss on early extinguishment of debt during the nine months ended September 30, 2020 of approximately $9.3 million was associated with the early repayment of the $160 Million Fixed-Rate Loan which was collateralized by the 1901 Market Street building. The property was sold during the nine months ended September 30, 2020. The loss, which modestly reduces the significant gain on sale, was comprised of a prepayment penalty and unamortized debt issuance costs and discounts associated with the loan.

Gain on sale of real estate assets during the nine months ended September 30, 2020 includes a gain of approximately $191.0 million recognized on the sale of the 1901 Market Street building.

Issuer and Guarantor Financial Information

Piedmont, through its wholly-owned subsidiary Piedmont Operating Partnership, LP ("Piedmont OP" or the "Issuer"), has issued senior unsecured notes payable of $350 million that mature in 2023, $400 million that mature in 2024, and two separate issuances of $300 million, that mature in 2030 and 2032, respectively, (collectively, the "Notes"). The Notes are senior unsecured obligations of Piedmont OP and rank equally in right of payment with all of Piedmont OP's other existing and future senior unsecured indebtedness and would be effectively subordinated in right of payment to any of Piedmont OP’s future mortgage or other secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and to all existing and future indebtedness and other liabilities of Piedmont OP’s subsidiaries, whether secured or unsecured.

The Notes are fully and unconditionally guaranteed by Piedmont Office Realty Trust, Inc. (the "Guarantor"), the parent entity that consolidates Piedmont OP and all other subsidiaries. By execution of the guarantee, the Guarantor guarantees to each holder of the Notes that the principal and interest on the Notes will be paid in full when due, whether at the maturity dates of the respective loans, or upon acceleration, upon redemption, or otherwise, and interest on overdue principal and interest on any overdue interest, if any, on the Notes and all other obligations of the Issuer to the holders of the Notes will be promptly paid in full. The Guarantor's guarantee of the Notes is its senior unsecured obligation and ranks equally in right of payment with all of the Guarantor's other existing and future senior unsecured indebtedness and guarantees. The Guarantor’s guarantee of the Notes is effectively subordinated in right of payment to any future mortgage or other secured indebtedness or secured guarantees of the Guarantor (to the extent of the value of the collateral securing such indebtedness and guarantees); and all existing and future indebtedness and other liabilities, whether secured or unsecured, of the Guarantor’s subsidiaries.

In the event of the bankruptcy, liquidation, reorganization or other winding up of Piedmont OP or the Guarantor, assets that secure any of their respective secured indebtedness and other secured obligations will be available to pay their respective obligations under the Notes or the guarantee, as applicable, and their other respective unsecured indebtedness and other unsecured obligations only after all of their respective indebtedness and other obligations secured by those assets have been repaid in full.

The non-Guarantors are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Notes, or to make any funds available therefore, whether by dividends, loans, distributions or other payments.

Net Operating Income by Geographic Segment

Our President and Chief Executive Officer has been identified as our chief operating decision maker ("CODM"), as defined by GAAP. Our CODM evaluates Piedmont's portfolio and assesses the ongoing operations and performance of its properties utilizing the following geographic segments: Dallas, Atlanta, Washington, D.C., Minneapolis, Boston, Orlando, and New York. These operating segments are also our reportable segments. As of September 30, 2021, we also owned two properties in Houston and one property in Chicago that do not meet the definition of an operating or reportable segment as the CODM does not regularly review these properties for purposes of allocating resources or assessing performance. Further, we do not maintain a significant presence or anticipate further investment in these markets. These three properties are included in "Corporate and other" below. See Note 11 to the accompanying consolidated financial statements for additional information and a reconciliation of Net income applicable to Piedmont to accrual-based net operating income ("NOI").

NOI decreased primarily as a result of the sale of 1901 Market Street building in Philadelphia, Pennsylvania in June 2020.

Funds From Operations ("FFO"), Core Funds From Operations ("Core FFO"), and Adjusted Funds From Operations
(“AFFO”)

Net income calculated in accordance with GAAP is the starting point for calculating FFO, Core FFO, and AFFO. These metrics are non-GAAP financial measures and should not be viewed as an alternative measurement of our operating performance to net income. Management believes that accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets 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. As a result, we believe that the additive use of FFO, Core FFO, and AFFO, together with the required GAAP presentation, provides a more complete understanding of our performance relative to our competitors and a more informed and appropriate basis on which to make decisions involving operating, financing, and investing activities.

30

Table of Contents
We calculate FFO in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as Net income (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 and investment in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. Other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do; therefore, our computation of FFO may not be comparable to the computation made by other REITs.

We calculate 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 or infrequent 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 our operating performance. We believe 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 our core recurring business operations. As a result, we believe 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 us; therefore, our computation of Core FFO may not be comparable to the computation made by other REITs.

We calculate AFFO by starting with Core FFO and adjusting for non-incremental capital expenditures and non-cash items including: non-real estate depreciation, straight-lined rent and fair value lease adjustments, non-cash components of interest expense and compensation expense. 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 our operating performance. We believe that AFFO is helpful to investors as a meaningful supplemental comparative performance measure of our ability to make incremental capital investments in new properties or enhancements to existing properties that improve revenue growth potential. Other REITs may not define AFFO in the same manner as us; therefore, our computation of AFFO may not be comparable to the computation of other REITs.

(2)We define non-incremental capital expenditures as capital expenditures of a recurring nature related to tenant improvements, leasing commissions, and building capital that do not incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives 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, and renovations that either enhance the rental rates of a building or change the property's underlying classification, such as from a Class B to a Class A property, are excluded from this measure. Non-incremental capital expenditures incurred during the nine months ended September 30, 2020 includes a $16 million leasing commission for the approximately 20-year, 520,000-square-foot renewal and expansion of the State of New York's lease at our 60 Broad Street building in New York City that was executed during the fourth quarter of 2019.

Property and Same Store Net Operating Income

Property Net Operating Income ("Property NOI") is a non-GAAP measure which we use to assess our operating results. We calculate Property NOI beginning with Net income (calculated in accordance with GAAP) before interest, income-related federal, state, and local taxes, depreciation and amortization and removing any impairment losses, 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. Furthermore, we remove general and administrative expenses, income associated with property management performed by us for other organizations, and other income or expense items such as interest income from loan investments or costs from the pursuit of non-consummated transactions. For Property NOI (cash basis), the effects of straight-lined rents and fair value lease revenue are also eliminated; while such effects are not adjusted in calculating Property NOI (accrual basis). 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 our operating performance. We believe that Property NOI, on either a cash or accrual basis, is helpful to investors as a supplemental comparative performance measure of income generated by our properties alone without our administrative overhead. Other REITs may not define Property NOI in the same manner as we do; therefore, our computation of Property NOI may not be comparable to that of other REITs.

We calculate Same Store Net Operating Income ("Same Store NOI") as Property NOI attributable to the properties (excluding undeveloped land parcels) that were (i) owned by us during the entire span of the current and prior year reporting periods; (ii) that were not being developed or redeveloped during those periods; and (iii) for which no operating expenses were capitalized during those periods. For Same Store NOI (cash basis), the effects of straight-lined rents and fair value lease revenue are also eliminated. Same Store NOI, on either a cash or accrual basis, 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 our operating performance. We believe 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 we do; therefore, our computation of Same Store NOI may not be comparable to that of other REITs.

(1)We calculate Earnings Before Interest, Taxes, Depreciation, and Amortization- Real Estate ("EBITDAre") in accordance with the current NAREIT definition. NAREIT currently defines EBITDAre as net income (computed in accordance with GAAP) adjusted for gains or losses from sales of property, impairment losses, 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 our operating performance. We believe that EBITDAre is helpful to investors as a supplemental performance measure because it provides a metric for understanding our 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). We also believe 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 us; therefore, our computation of EBITDAre may not be comparable to that of such other REITs.

We believe that Core EBITDA is helpful to investors as a supplemental performance measure because it provides a metric for understanding the performance of our 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 our business.

Overview

Our portfolio is a geographically diverse group of properties concentrated primarily in select sub-markets within seven major Eastern U.S. office markets, with a majority of our Annualized Lease Revenue ("ALR") being generated from the Sunbelt. We typically lease space to large, creditworthy corporate or governmental tenants on a long-term basis. As of September 30, 2021, our average lease is approximately 15,000 square feet with six years of lease term remaining. Consequently, leased percentage, as well as rent roll ups and roll downs, which we experience as a result of re-leasing, can fluctuate widely between buildings and between tenants, depending on when a particular lease is scheduled to commence or expire.

Leased Percentage

Our portfolio was 85.9% leased as of September 30, 2021, as compared to approximately 86.8% leased as of December 31, 2020. As of September 30, 2021, we had only one lease greater than 1% of our ALR that is scheduled to expire prior to December 31, 2022. This lease at our 750 West John Carpenter Freeway asset (assigned to the Dallas geographic reportable segment) represents 1.2% of our ALR, and is scheduled to expire during the fourth quarter of 2022. As the economy has continued to recover from the impacts of the COVID-19 pandemic, leasing activity across our portfolio has improved; however, to the extent new leases for currently vacant space outweigh or fall short of scheduled expirations, such leases would increase or decrease our overall leased percentage, respectively.

Impact of Downtime, Abatement Periods, and Rental Rate Changes

Commencement of new leases typically occurs 6-18 months after the lease execution date, after refurbishment of the space is completed. The downtime between a lease expiration and the new lease's commencement can negatively impact Property NOI and Same Store NOI comparisons (both accrual and cash basis). In addition, office leases, both new and renewal, often contain upfront rental and/or operating expense abatement periods which delay the cash flow benefits of the lease even after the new lease or renewal has commenced and negatively impact Property NOI and Same Store NOI on a cash basis until such abatements expire. As of September 30, 2021, we had approximately 770,000 square feet of executed leases for vacant space yet to commence or under rental abatement.

37

Table of Contents
If we are unable to replace expiring leases with new or renewal leases at rental rates equal to or greater than the expiring rates, rental rate roll downs could occur and negatively impact Property NOI and Same Store NOI comparisons. As mentioned above, our geographically diverse portfolio and the magnitude of some of our tenant's leased space can result in rent roll ups and roll downs that can fluctuate widely on a building-by-building and a quarter-to-quarter basis. During the three months ended September 30, 2021, we experienced a 16.1% and 10.5% roll up in accrual and cash rents, respectively, on executed leases related to space vacant one year or less. During the nine months ended September 30, 2021, we experienced a 17.0% and 8.2% roll up in accrual and cash rents, respectively, on executed leases related to space vacant one year or less.

Same Store NOI increased by 11.6% and 5.0% on a cash and accrual basis, respectively, for the three months ended September 30, 2021 and increased 6.7% and 2.8% on a cash and accrual basis, respectively, for the nine months ended September 30, 2021. The primary drivers of the increases in both metrics for both periods included rising rental rates, decreased operating expenses, particularly related to our landlord's portion of real estate taxes, as well as the expiration of abatements at certain properties, offset by lower overall occupancy. Property NOI and Same Store NOI comparisons for any given period fluctuate as a result of the mix of net leasing activity in individual properties during the respective period.

Election as a REIT

We have elected to be taxed as a REIT under the Code and have operated as such beginning with our taxable year ended December 31, 1998. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of our adjusted REIT taxable income, computed without regard to the dividends-paid deduction and by excluding net capital gains attributable to our stockholders, as defined by the Code. As a REIT, we generally will not be subject to federal income tax on income that we distribute to our stockholders. If we fail to qualify as a REIT in any taxable year, we may be subject to federal income taxes on our taxable income for that year and for the four years following the year during which qualification is lost and/or penalties, unless the IRS grants us relief under certain statutory provisions. Such an event could materially adversely affect our net income and net cash available for distribution to our stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT and intend to continue to operate in the foreseeable future in such a manner that we will remain qualified as a REIT for federal income tax purposes. We have elected to treat one of our wholly-owned subsidiaries as a taxable REIT subsidiary. This subsidiary performs non-customary services for tenants of buildings that we own and real estate and non-real estate related-services; however, any earnings related to such services performed by our taxable REIT subsidiary are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, our investments in taxable REIT subsidiaries cannot exceed 20% of the value of our total assets.

Inflation

We are exposed to inflation risk, as income from long-term leases is the primary source of our cash flows from operations. There are provisions in the majority of our tenant leases that are intended to protect us from, and mitigate the risk of, the impact of inflation. These provisions include rent steps, reimbursement billings for operating expense pass-through charges, real estate tax, and insurance reimbursements on a per square-foot basis, or in some cases, annual reimbursement of operating expenses above certain per square-foot allowances. However, due to the long-term nature of the leases, the leases may not readjust their reimbursement rates frequently enough to fully cover inflation.

Off-Balance Sheet Arrangements

We are not dependent on off-balance sheet financing arrangements for liquidity. As of September 30, 2021, we had no off-balance sheet arrangements.

Application of Critical Accounting Policies

Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgement in the application of accounting policies, including making estimates and assumptions. These judgements affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgement or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied, thus, resulting in a different presentation of the financial statements. Additionally, other companies may utilize different estimates that may impact comparability of our results of operations to those of companies in similar businesses. Refer to our Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of our critical accounting policies. There have been no material changes to these policies during the nine months ended September 30, 2021.

(1)Contractual obligations do not include amounts committed for tenant or capital improvements under leases where Piedmont is the lessor. However, see Note 6 to our accompanying consolidated financial statements for details concerning our individually material lease commitments, the timing of which may fluctuate. Additionally, Piedmont does not have any ground leases, nor does Piedmont have any material obligations as lessee under operating lease agreements as of September 30, 2021.
(2)Amounts include principal payments only and balances outstanding as of September 30, 2021, not including approximately $12.9 million of net unamortized issuance discounts and debt issuance costs paid to lenders. We made interest payments, including payments under our interest rate swaps, of approximately $41.5 million during the nine months ended September 30, 2021, and expect to pay interest in future periods on outstanding debt obligations based on the rates and terms disclosed herein and in Note 3 to our accompanying consolidated financial statements.

Commitments and Contingencies
We are subject to certain commitments and contingencies with regard to certain transactions. Refer to Note 6 to our consolidated financial statements for further explanation. Examples of such commitments and contingencies include:
Commitments Under Existing Lease Agreements;
Contingencies Related to Tenant Audits/Disputes; and
Contingencies Related to the COVID-19 Pandemic.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our future income, cash flows, and estimated fair values of our financial instruments depend in part upon prevailing market interest rates. Market risk is the exposure to loss resulting from changes in interest rates, foreign currency, exchange rates, commodity prices, and equity prices. Our potential for exposure to market risk includes interest rate fluctuations in connection with borrowings under our $500 Million Unsecured 2018 Line of Credit and the $250 Million Unsecured 2018 Term Loan. As a result, the primary market risk to which we believe we are exposed is interest rate risk. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control contribute to interest rate risk, including changes in the method pursuant to which the LIBOR rates are determined. Furthermore, the United Kingdom Financial Conduct Authority, which regulates LIBOR, has announced that USD LIBOR will no longer by published after June 30, 2023. Piedmont has completed an initial evaluation of its credit agreements which reference LIBOR and determined that each of these agreements already contain "fallback" language allowing for the establishment of an alternate rate of interest that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the U.S. at that time by Piedmont and the respective agent, as defined in the respective agreements. Piedmont will continue to evaluate its contracts as it approaches the end date for LIBOR.

Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flow primarily through a low-to-moderate level of overall borrowings, as well as managing the variability in rate fluctuations on our outstanding debt. As such, all of our debt other than the $500 Million Unsecured 2018 Line of Credit and $150 million of our $250 Million Unsecured 2018 Term Loan is currently based on fixed or effectively-fixed interest rates to hedge against volatility in the credit markets. We do not enter into derivative or interest rate transactions for speculative purposes, as such all of our debt and derivative instruments were entered into for other than trading purposes.

The estimated fair value of our debt was approximately $1.7 billion as of September 30, 2021 and December 31, 2020. Our interest rate swap agreements in place as of September 30, 2021 and December 31, 2020 carried a notional amount totaling $100 million with a weighted-average fixed interest rate (not including the corporate credit spread) of 2.61%.

39

Table of Contents
As of September 30, 2021, our total outstanding debt subject to fixed, or effectively fixed, interest rates totaling approximately $1.5 billion has an average effective interest rate of approximately 3.51% per annum with expirations ranging from 2023 to 2032. A change in the market interest rate impacts the net financial instrument position of our fixed-rate debt portfolio but has no impact on interest incurred or cash flows for that portfolio.

As of September 30, 2021, we had $78 million outstanding on our $500 Million Unsecured 2018 Line of Credit. Our $500 Million Unsecured 2018 Line of Credit currently has a stated rate of LIBOR plus 0.90% per annum (based on our current corporate credit rating), resulting in a total interest rate of 0.99%. The current stated interest rate spread on $150 million of the $250 Million Unsecured 2018 Term Loan that is not effectively fixed through interest rate swaps is LIBOR plus 0.95% (based on our current corporate credit rating), which, as of September 30, 2021, resulted in a total interest rate on $150 million of the $250 Million Unsecured 2018 Term Loan of 1.04%. To the extent that we borrow additional funds in the future under the $500 Million Unsecured 2018 Line of Credit or potential future variable-rate lines of credit, we would have exposure to increases in interest rates, which would potentially increase our cost of debt. Additionally, a 1.0% increase in variable interest rates on our existing outstanding borrowings as of September 30, 2021 would increase interest expense approximately $2.3 million on a per annum basis.

ITEM 4.    CONTROLS AND PROCEDURES
Management’s Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of management, including the Principal Executive Officer and the Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”) as of the end of the quarterly period covered by this report. Based upon that evaluation, the Principal Executive Officer and the Principal Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report in providing a reasonable level of assurance that information we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in applicable SEC rules and forms, including providing a reasonable level of assurance that information required to be disclosed by us in the reports we file under the Exchange Act is accumulated and communicated to our management, including the Principal Executive Officer and the Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

We are not subject to any material pending legal proceedings. However, we are subject to routine litigation arising in the ordinary course of owning and operating real estate assets. Our management expects that these ordinary routine legal proceedings will be covered by insurance and does not expect these legal proceedings to have a material adverse effect on our financial condition, results of operations, or liquidity. Additionally, management is not aware of any legal proceedings against Piedmont contemplated by governmental authorities.

ITEM 1A.    RISK FACTORS
The proposed new regulation concerning mandatory COVID-19 vaccination of employees could have a material adverse impact on our business and results of operations.

On September 9, 2021, President Biden announced a proposed new rule requiring all employers with at least 100 employees to ensure that their employees are fully vaccinated or require unvaccinated workers to get a negative test at least once a week. The Department of Labor’s Occupational Safety and Health Administration is drafting an emergency regulation to carry out this mandate, which is expected to take effect in the coming weeks. It remains unclear, among other things, if the vaccine mandate will apply to all employees or only to employees who work in the office, and how compliance will be documented.

It is currently not possible to predict with certainty the exact impact the new regulation would have on us, but it may result in employee attrition. If we were to lose employees, it could have an adverse effect on future revenues and costs, which could be material.

There have been no other known material changes, other than as described above, from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

ITEM 2.    UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
