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 our executive officers on our behalf, may from time to time make forward-looking statements in reports and other documents we file 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 our 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; 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 our 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 we operate, competitive conditions, and general economic conditions. These assumptions could prove inaccurate. The forward-looking statements also involve certain known and unknown 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 our ability to control or predict. Such factors include, but are not limited to, the following:

Economic, regulatory, socio-economic (including work from home), technological (e.g. Metaverse, Zoom, etc), and other changes (including accounting standards) 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 Annualized Lease Revenue (“ALR”) (see definition below);
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 lead 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 rising interest rates, 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, or future cybersecurity attacks against any of our properties or 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, 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, 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 which we listed our common stock;
Changes in the method pursuant to which the London Interbank Offered Rate ("LIBOR") and the Secured Overnight Financing Rate (“SOFR”) rates are determined and the planned phasing out of United States dollar ("USD") LIBOR after June 2023;
Changing capital reserve requirements on our lenders and rapidly rising interest rates in the public bond markets could impact our ability to finance properties or refinance existing debt or significantly increase operating/financing costs;
3

The effect of future offerings of debt or equity securities on the value of our common stock;
Additional risks and costs associated with inflation and continuing increases in the rate of inflation, including the possibility of a recession that could negatively impact our operations and the operations of our tenants and their ability to pay rent;
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;
Actual or threatened public health epidemics or outbreaks, such as experienced during the COVID-19 pandemic, as well as governmental and private measures taken to combat such health crises, could have a material adverse effect on our business operations and financial results;
The adequacy of our general reserve related to tenant lease-related assets or the establishment of any other reserve in the future; and
Other factors, including the risk factors discussed under Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2021.

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. Further, forward-looking statements speak only as of the date they are made, and management undertakes no obligation to update publicly any of them in light of new information or future events.

Information Regarding Disclosures Presented

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.

PIEDMONT OFFICE REALTY TRUST, INC.
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2022
(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 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, 2022, Piedmont owned 53 in-service, Class A office properties and one redevelopment asset, primarily located within the Sunbelt. As of September 30, 2022, the in-service portfolio comprised approximately 16.8 million square feet (unaudited) and was 86.8% 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, 2021.

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.

12

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, 2022 and 2021, respectively, as follows (in thousands):

Operating leases where Piedmont is the lessee relate primarily to office space in buildings owned by third parties. Piedmont's right of use asset and corresponding lease liability was approximately $0 and $60,000 as of September 30, 2022 and December 31, 2021, respectively. The right of use asset is recorded as a component of prepaid expenses and other assets, whereas the corresponding liability is presented as a component of accounts payable, accrued expenses, and accrued capital expenditures in the accompanying consolidated balance sheets. For both the three and nine months ended September 30, 2022 and 2021, Piedmont recognized approximately $20,000 and $60,000, respectively, of operating lease costs related to these office space leases. As of September 30, 2022, the lease term of Piedmont's right of use asset had ended; however, the lease was renewed effective October 1, 2022 for 26 months.

Intangible Assets and Liabilities Resulting from Purchasing Real Estate Assets

Upon the acquisition of real properties, Piedmont allocates the purchase price of the properties to tangible assets, consisting of land, building, site improvements, and identified intangible assets and liabilities, including the value of in-place leases, based in each case on Piedmont's estimate of their fair values in accordance with Accounting Standards Codification ("ASC") 820 Fair Value Measurements.

Gross intangible lease assets and liabilities arising from in-place leases, inclusive of amounts classified as real estate assets held for sale, recorded at acquisition as of September 30, 2022 and December 31, 2021, respectively, are as follows (in thousands):

3.    Acquisitions

During the three months ended September 30, 2022, Piedmont acquired 100% of the ownership interest in 1180 Peachtree Street in Midtown Atlanta, Georgia (part of the Atlanta geographic segment), consisting of 691,092 square feet and 95% leased. The net contractual purchase price of $465.7 million included the assumption of an existing $197 million, 4.10% mortgage secured by the property. The remaining cash portion of the purchase price was primarily funded using a new $200 Million Unsecured Term Loan Facility (further described in Note 4 below), as well as cash on hand and our $600 Million Unsecured 2022 Line of Credit.

The purchase price of 1180 Peachtree Street, inclusive of approximately $2.2 million of closing costs, was allocated as follows:

1180 Peachtree Street
Land $ 56,932 
Building and improvements 336,219 
Intangible lease assets (1)
53,426 
Lease acquisition costs, net of tenant credits received from seller (1)

(31,355)
Total allocated purchase price $ 467,899 
Assumption of secured mortgage note (197,000)
Net cash paid upon acquisition $ 270,899 

(1)Amortization of in-place lease intangibles and lease acquisition costs are recognized using the straight-line method over approximately 7.4 years, the average remaining life of in-place leases.


4.    Debt

As noted above, in conjunction with the acquisition of 1180 Peachtree Street during the three months ended September 30, 2022, Piedmont entered into a Loan Assignment and Assumption Agreement for an existing $197 million fixed rate mortgage secured by the property (the “$197 Million Fixed Rate Mortgage”). The $197 Million Fixed Rate Mortgage has a remaining term of approximately six years and a final maturity date of October 1, 2028. Interest only at a fixed rate of 4.10% per annum is payable until October 1, 2023, at which point the loan becomes amortizing.

Piedmont also entered into a new $200 million, floating-rate, unsecured term loan facility (the “$200 Million Unsecured Term Loan Facility”) during the three months ended September 30, 2022 to fund the majority of the cash portion of the 1180 Peachtree Street purchase price. The term of the $200 Million Unsecured Term Loan Facility is six months, with an option to extend twice for an additional three months for a final maturity date of July 24, 2023. Piedmont may prepay the loan in whole or in part, at any time without premium or penalty. The stated interest rate spread over Adjusted Term SOFR can vary from 0.80% to 1.65% based upon the then current credit rating of Piedmont. As of September 30, 2022, the applicable interest rate spread on the loan was 1.00%.

During the nine months ended September 30, 2022, Piedmont amended and restated its $500 Million Unsecured 2018 Line of Credit which had an initial maturity date of September 30, 2022. As amended and restated, the capacity of the line of credit has been expanded to $600 million (the "$600 Million Unsecured 2022 Line of Credit"). The term of the new $600 Million Unsecured 2022 Line of Credit was extended to June 30, 2026, and Piedmont may extend the term for up to one additional year (through two available six-month extensions) provided Piedmont is not then in default and all representations and warranties are true and correct in all material respects and upon payment of applicable extension fees. Under certain terms of the agreement, Piedmont may increase the new facility by up to an additional $500 million, to an aggregate size of $1.1 billion, provided that no existing bank has any obligation to participate in such increase. Piedmont paid customary arrangement and upfront fees to the lenders in connection with the closing of the new facility.

The $600 Million Unsecured 2022 Line of Credit has the option to bear interest at varying levels (determined with reference to the greater of the credit rating for Piedmont or Piedmont OP) based on the Adjusted Term SOFR Rate, Adjusted Daily Effective SOFR Rate, or the Base Rate, all as defined in the facility agreement. Further, the Base Rate is defined as the greater of the
15

prime rate, the federal funds rate plus 0.5%, or the Adjusted Term SOFR Rate for a one-month period plus 1.0%. The term SOFR loans are available with interest periods selected by Piedmont of one, three, or six months. The stated interest rate spread over Adjusted SOFR can vary from 0.725% to 1.4% based upon the greater of the then current credit rating of Piedmont or Piedmont OP. As of September 30, 2022, based upon Piedmont’s current BBB credit rating, the current stated Adjusted SOFR spread on the loan is 0.85%.

The $600 Million Unsecured 2022 Line of Credit and the $200 Million Unsecured Term Loan Facility have certain financial covenants that require, among other things, the maintenance of an unencumbered interest rate coverage ratio of at least 1.75, an unencumbered leverage ratio of at least 1.60, a fixed charge coverage ratio of at least 1.50, a leverage ratio of no more than 0.60, and a secured debt ratio of no more than 0.40.

(1)All of Piedmont’s outstanding debt as of September 30, 2022 is unsecured and interest-only until maturity, except for the $197 Million Fixed Rate Mortgage, secured by 1180 Peachtree Street, which will begin amortizing principal in October 2023.
(2)Effective rate after consideration of settled or in-place interest rate swap agreements and issuance discounts.
(3)On a periodic basis, Piedmont may select from multiple interest rate options, including the prime rate and various-length SOFR locks on all or a portion of the principal. All SOFR selections are subject to an additional spread over the selected rate based on Piedmont’s current credit rating.
(4)Piedmont intends to repay the $200 Million Unsecured Term Loan Facility due January 2023 using the net sales proceeds from the future disposition of properties, cash on hand from operations, and/or draws under its existing $600 Million Unsecured 2022 Line of Credit. Additionally, Piedmont may extend the term for up to six additional months (through two available three month extensions to a final extended maturity date of July 24, 2023) provided Piedmont is not then in default and upon payment of extension fees.
(5)Piedmont currently intends to repay the $350 Million Unsecured Senior Notes due 2023 through debt refinancing, cash on hand from operations, and/or draws under its existing $600 million Unsecured 2022 Line of Credit.
(6)The facility has a stated variable rate; however, Piedmont has entered into interest rate swap agreements which effectively fix, exclusive of changes to Piedmont's credit rating, $100 million of the principal balance to 3.56% through the maturity date of the loan. For the remaining variable portion of the loan, Piedmont may periodically select from multiple interest rate options, including the prime rate and various-length LIBOR locks on all or a portion there of. All LIBOR selections are subject to an additional spread

over the selected rate based on Piedmont’s current credit rating. The rate presented is the weighted-average rate for the effectively fixed and variable portions of the debt outstanding as of September 30, 2022 (see Note 5 for more detail).
(7)The $500 Million Unsecured 2018 Line of Credit was amended and restated during the nine months ended September 30, 2022 and is now reflected as the $600 Million Unsecured 2022 Line of Credit. The $500 Million Unsecured 2018 Line of Credit had a stated rate of LIBOR + 0.90% as of December 31, 2021.
(8)Piedmont may extend the term for up to one additional year (through two available six month extensions to a final extended maturity date of June 30, 2027) provided Piedmont is not then in default and upon payment of extension fees.
(9)Weighted average is based on contractual balance of outstanding debt and the stated or effectively fixed interest rates as of September 30, 2022.

Piedmont made interest payments on all debt facilities, including interest rate swap cash settlements, of approximately $18.3 million and $16.2 million for the three months ended September 30, 2022 and 2021, respectively, and approximately $46.9 million and $41.5 million for the nine months ended September 30, 2022 and 2021, respectively. Also, Piedmont capitalized interest of approximately $1.1 million and $1.0 million for the three months ended September 30, 2022 and 2021, respectively, and approximately $3.2 million and $2.7 million for the nine months ended September 30, 2022 and 2021, respectively. As of September 30, 2022, Piedmont believes it was in compliance with all financial covenants associated with its debt instruments.

See Note 6 for a description of Piedmont’s estimated fair value of debt as of September 30, 2022.

5.    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. The settlement resulted in a gain of approximately $0.6 million, which was recorded as accumulated other comprehensive income ("OCI") and is being amortized as an offset to interest expense over 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 30 months. A detail of Piedmont’s interest rate derivatives outstanding as of September 30, 2022 is as follows:

Piedmont presents its interest rate derivatives on its consolidated balance sheets on a gross basis as interest rate swap assets and interest rate swap liabilities. A detail of Piedmont’s interest rate derivatives on a gross and net basis as of September 30, 2022 and December 31, 2021, respectively, is as follows (in thousands):

Piedmont estimates that approximately $1.3 million will be reclassified from OCI as an decrease in interest expense over the next twelve months. Additionally, see Note 6 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. However, as of September 30, 2022, both of Piedmont's interest rate swap agreements are in an asset position. 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.

6.    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, 2022 and December 31, 2021, respectively (in thousands):

(1)For the periods presented, the carrying value of these financial instruments, net of applicable allowance, approximates estimated fair value due to their short-term maturity.

Piedmont's debt was carried at book value as of September 30, 2022 and December 31, 2021, and its notes receivable were carried at book value as of December 31, 2021; 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. 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
18

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 and debt as of December 31, 2021 and the estimated fair value of debt as of September 30, 2022 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 5, are classified as “Interest rate swaps” in the accompanying consolidated balance sheets and were carried at estimated fair value as of September 30, 2022 and December 31, 2021. 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 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, 2022 and December 31, 2021, 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 derivatives to be Level 3 financial instruments.

7.    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. Such commitments will be accrued and capitalized as the related expenditures are incurred. In addition to the amounts that Piedmont has already committed to as a part of executed leases, Piedmont also anticipates continuing to incur similar market-based tenant improvement allowances and leasing commissions in conjunction with procuring future leases for its 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 size of the leased square footage and the competitive market conditions of the particular office market at the time a lease is being negotiated.

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, 2022 or 2021.

Also during the nine months ended September 30, 2022, Piedmont received $118.5 million in proceeds from the payoff of two notes receivable that Piedmont had received in late 2020 from the buyer of its remaining New Jersey properties. The proceeds were used to pay down Piedmont's unsecured line of credit.

9.    Stock Based Compensation
The Compensation Committee of Piedmont's Board of Directors has granted deferred stock award units to eligible employees at its discretion 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. None of the shares potentially earned are awarded until the end of the multi-year performance period (or upon termination) and vest upon award and are pro-rated if certain terminations occur before the end of the multi-year period. The grant date fair value of the multi-year performance share awards is estimated using the Monte Carlo valuation method.

During the three months ended September 30, 2022 and 2021, Piedmont recognized approximately $2.0 million and $1.8 million, respectively, of compensation expense related to stock awards, all of which related to the amortization of unvested and potential stock awards and fair value adjustment for liability awards. During the nine months ended September 30, 2022 and 2021, Piedmont recognized approximately $6.9 million and $8.2 million, respectively, of compensation expense related to stock awards, of which $5.8 million and $6.9 million is related to the amortization of unvested and potential stock awards and fair value adjustment for liability awards. During the nine months ended September 30, 2022, 318,686 shares (net of shares surrendered upon vesting to satisfy required minimum tax withholding obligations) were issued to employees and independent directors. As of September 30, 2022, approximately $8.0 million of unrecognized compensation cost related to unvested and potential stock awards remained, which Piedmont will record in its consolidated statements of income over a weighted-average vesting period of approximately one year.

Amounts in restricted cash and escrows typically represent: escrow accounts required for future property repairs; escrow accounts for the payment of real estate taxes as required under certain of Piedmont's debt agreements; earnest money deposited by a buyer to secure the purchase of one of Piedmont's properties; or security or utility deposits held for tenants as a condition of their lease agreement.

11.    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, 2022 and 2021, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of approximately 194,330 and 145,222, respectively, and for the nine months ended September 30, 2022 and 2021, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of 346,695 and 313,140, respectively.

12.    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: Atlanta, Dallas, Washington, D.C., Boston, Orlando, New York, and Minneapolis. These operating segments are also Piedmont’s reportable segments. As of September 30, 2022, Piedmont also owned two properties in Houston 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 this market. These two properties are the primary contributors to accrual-based net operating income ("NOI") included in "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.

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, 2021.

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 borrowings under our $600 Million Unsecured 2022 Line of Credit as our primary sources of immediate liquidity. When necessary, we may seek other new secured or unsecured borrowings from third party lenders or issue other debt or equity securities as additional sources of capital. The nature and timing of these additional sources of capital will be highly dependent on market conditions. We believe that we have sufficient liquidity to meet our obligations for the foreseeable future.

During the quarter ended September 30, 2022, we acquired 1180 Peachtree Street, an iconic, 41-story, Class AA, LEED Platinum, trophy office building located at the epicenter of Midtown Atlanta, Georgia, for a net purchase price of approximately $465 million, comprised of approximately $268 million in cash and the assumption of an existing $197 million, 4.10% mortgage secured by the property. The cash portion of the net purchase price was funded primarily from the proceeds of a $200 million, unsecured, floating rate, term loan put in place during the three months ended September 30, 2022 and bearing interest at Adjusted Term SOFR + 100 bps. On a longer-term basis, we anticipate using the net sales proceeds from the disposition of non-strategic assets over the next several quarters to ultimately fund the acquisition and maintain an approximately leverage-neutral balance sheet.

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, 2022 and 2021 we incurred the following types of capital expenditures (in thousands):

Nine Months Ended
September 30, 2022 September 30, 2021
Capital expenditures for redevelopment/renovations $ 49,592  $ 39,422 
Other capital expenditures, including building and tenant improvements 45,915  44,055 
Total capital expenditures (1)
$ 95,507  $ 83,477 

(1)Of the total amounts paid, approximately $5.2 million and $4.5 million relates to soft costs such as capitalized interest, payroll, and other property operating costs for the nine months ended September 30, 2022 and 2021, respectively.

"Capital expenditures for redevelopment/renovations" during both the nine months ended September 30, 2022 and 2021 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; and our Galleria buildings in Atlanta, Georgia, among others.

"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 sometimes results in leases for large blocks of space to credit-worthy tenants, our leasing success can result in capital outlays that vary significantly from one reporting period to another depending upon the specific leases executed. For leases executed during the nine months ended September 30, 2022, we committed to spend approximately $4.93 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as compared to $3.95 (net of expired lease commitments) for the nine months ended September 30, 2021. Commitments per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) for the nine months ended September 30, 2021 were unusually low as they reflected the 330,000 square foot, five-year extension of the New York City lease at our 60 Broad Street asset, which did not include a tenant improvement allowance.

26

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 size of the leased square footage and 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 or when we otherwise believe such stock repurchases are prudent. As of September 30, 2022, we had approximately $150.5 million of remaining capacity under the program which may be used for share repurchases through February 2024. Finally, we have two scheduled debt maturities, the $200 Million Unsecured Term Loan Facility and the $350 Million Unsecured Senior Notes, within the next twelve months, which we intend to repay through sales of select properties, debt refinancing, cash on hand, cash flow from operations, and/or draws under our existing $600 Million Unsecured 2022 Line of Credit.

We may also use capital resources to pay dividends to our stockholders. 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, 2022 was approximately $3.3 million, or $0.03 per diluted share, as compared with net income applicable to common stockholders of $11.3 million, or $0.09 per diluted share, for the three months ended September 30, 2021. The decrease reflects a $7.3 million increase in depreciation and amortization expense primarily resulting from acquisition activity during the current period, as well as a $4.8 million increase in interest expense. The increase in interest expense was driven by increased interest rates on our variable rate debt, as well as a higher average debt balance outstanding during the quarter. Other income also decreased approximately $2.0 million for the three months ended September 30, 2022 as compared to the three months ended September 30, 2021 due to the payoff of notes receivable due from the purchaser of our New Jersey Portfolio in March of 2022.

Revenue

Rental and tenant reimbursement revenue increased approximately $12.1 million for the three months ended September 30, 2022, as compared to the same period in the prior year. The increase was primarily due to capital recycling activity (the 1180 Peachtree Street purchase), rental rate increases associated with recent leasing activity across the portfolio, and higher tenant reimbursements as a result of higher recoverable operating expenses as compared to the prior period.

Other property related income increased approximately $1.2 million for the three months ended September 30, 2022 as compared to the same period in the prior year primarily due to increased parking revenue associated with properties acquired during the twelve months ended September 30, 2022 and higher transient parking volume at our buildings during the current period.

Expense

Property operating costs increased approximately $7.3 million for the three months ended September 30, 2022, as compared to the same period in the prior year. The variance was primarily due to higher recoverable operating expenses such as janitorial and utilities resulting from higher tenant utilization during the current period as compared to the prior period. Higher real estate taxes in certain jurisdictions associated with increased assessed property values also contributed to the increase, as well as acquisition activity completed during the twelve months ended September 30, 2022.

Depreciation expense increased approximately $4.4 million for the three months ended September 30, 2022 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 July 1, 2021 as well as capital recycling activity during the twelve months ended September 30, 2022.

Amortization expense increased approximately $2.9 million for the three months ended September 30, 2022 as compared to the same period in the prior year primarily due to additional amortization associated with property acquisitions during the twelve months ended September 30, 2022, partially offset by certain lease intangible assets at our existing properties becoming fully amortized during the twelve months ended September 30, 2022.

28

General and administrative expense decreased approximately $0.4 million for the three months ended September 30, 2022 as compared to the same period in the prior year, primarily reflecting decreased accruals for potential performance-based compensation.

Other Income (Expense)

Interest expense increased approximately $4.8 million for the three months ended September 30, 2022 as compared to the same period in the prior year primarily driven by a higher average debt balance outstanding during the quarter as a result of the purchase of 1180 Peachtree Street, as well as increased interest rates on our variable rate debt.

Other income/(expense) decreased approximately $2.0 million for the three months ended September 30, 2022 as compared to the same period in the prior year due to the payoff of notes receivable due from the purchaser of our New Jersey Portfolio in March of 2022.

Revenue

Rental and tenant reimbursement revenue increased approximately $23.3 million for the nine months ended September 30, 2022 as compared to the same period in the prior year. The increase was primarily due to capital recycling activity, rental rate increases associated with recent leasing activity across the portfolio, and higher tenant reimbursements as a result of higher recoverable operating expenses as compared to the prior period.

Other property related income increased approximately $3.3 million for the nine months ended September 30, 2022 as compared to the same period in the prior year primarily due to higher transient parking at our buildings during the current period, as compared to the prior period, and additional parking revenue associated with properties acquired during the twelve months ended September 30, 2022.

Expense

Property operating costs increased approximately $11.5 million for the nine months ended September 30, 2022 as compared to the same period in the prior year. The variance was primarily due to higher recoverable operating expenses such as janitorial and utilities resulting from higher tenant utilization during the current period, and capital recycling activity during the twelve months ended September 30, 2022.

Depreciation expense increased approximately $10.2 million for the nine months ended September 30, 2022 as compared to the same period in the prior year. The increase was primarily due to additional building and tenant improvements acquired and/or placed in service during the twelve months ended September 30, 2022.

Amortization expense increased approximately $3.0 million for the nine months ended September 30, 2022 as compared to the same period in the prior year primarily due to additional amortization associated with property acquisitions during the twelve months ended September 30, 2022, partially offset by certain lease intangible assets at our existing properties becoming fully amortized during the twelve months ended September 30, 2022.

General and administrative expenses decreased approximately $1.2 million for the nine months ended September 30, 2022 as compared to the same period in the prior year, primarily reflecting decreased accruals for potential performance-based compensation.

Other Income (Expense)

Interest expense increased approximately $7.5 million for the nine months ended September 30, 2022 as compared to the same period in the prior year primarily driven by a higher average debt balance outstanding during the current period as a result of the purchase of 1180 Peachtree Street, as well as increased interest rates on our variable rate debt. This increase was partially offset by a $0.5 million increase in capitalized interest associated with various redevelopment projects in progress during the nine months ended September 30, 2022.

Other income decreased approximately $5.0 million for the nine months ended September 30, 2022 as compared to the same period in the prior year due to the payoff of notes receivable due from the purchaser of our New Jersey Portfolio in March of 2022.

Gain on sale of real estate assets during the nine months ended September 30, 2022 primarily consisted of the gain recognized on the sale of the 225 & 235 Presidential Way buildings, which closed in January of 2022.

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 each, 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 Piedmont OP’s mortgage or any other future 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.
