ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2024 and 2023, and for the years ended December 31, 2024, 2023, and 2022, included elsewhere in this Annual Report on Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements” preceding Part I of this report and “Risk Factors" set forth in Item 1A. of this report.

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. On February 13, 2025, we amended our $200 Million Unsecured 2024 Term Loan to increase the principal amount of the loan by $125 million to a total of $325 million principal amount outstanding and to add two six-month extension options for a final maturity date of January 29, 2028, provided that we are not then in default and upon payment of extension fees. The net proceeds from the increased principal and our $600 Million Unsecured 2022 Line of Credit, along with cash on hand, were used to repay our $250 Million Unsecured 2018 Term Loan that was scheduled to mature in March of 2025.

Also subsequent to December 31, 2024, Piedmont recast the $600 Million Unsecured 2022 Line of Credit to extend the maturity date to June 30, 2028, with two additional one-year extension options, for a final maturity date of June 30, 2030, provided that we are not then in default and upon payment of extension fees. Consequently, we currently have no debt with a final maturity until 2028; however, as part of our overall debt management strategies, 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.

As of the date of this filing we had approximately $500 million of capacity available under our $600 Million Unsecured 2022 Line of Credit, and we believe that we have sufficient liquidity to meet our obligations for the foreseeable future.

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 years ended December 31, 2024 and 2023, we incurred the following types of capital expenditures (in thousands):

(1)Of the total amounts paid, approximately $19.9 million and $10.1 million related to soft costs such as capitalized interest, payroll, and other general and administrative expenses for the year ended December 31, 2024 and 2023, respectively.

"Capital expenditures for redevelopment/renovations" during the years ended December 31, 2024 and 2023 related to building upgrades, primarily to the lobbies and the addition of tenant amenities at certain of our buildings, including: Galleria Towers in Dallas, Texas; The Exchange in Orlando, Florida; 999 Peachtree Street and Galleria on the Park in Atlanta, Georgia, and Meridian in suburban Minneapolis, Minnesota, among others, most of which were substantially completed during 2024.

"Other capital expenditures, including building and tenant improvements" include all other capital expenditures during the respective period and are typically comprised of tenant and building improvements necessary to lease, maintain, or provide enhancements, including energy efficient equipment, to our existing portfolio of office properties.

We currently do not anticipate incurring any unusually large or material capital expenditures within any given year in order to meet recognized sustainable development standards, and achieve our environmental impact goals.

Given that our operating model frequently results in leases for multiple blocks of space to credit-worthy tenants, our leasing success can result in capital outlays which vary from one reporting period to another based upon the specific leases executed. For leases executed during the year ended December 31, 2024, we have committed to spend approximately $5.67 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as

33

compared to $5.22 (net of expired lease commitments) for the year ended December 31, 2023. As of December 31, 2024, we had two individually significant unrecorded tenant allowance commitments greater than $10 million.

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, length of the lease term, and the competitive market conditions of the particular office market at the time a lease is being negotiated, in addition to the impact of inflation and rising costs of construction.

Although reducing outstanding debt remains our priority, subject to the identification and availability of a few, select 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. Additionally, although we have no final debt maturity until 2028, we may use capital to repay debt obligations when we deem it prudent to refinance or reduce various obligations.

We 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; (vii) our desire to reduce overall leverage; and (viii) 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, including to pay dividends to our stockholders.

Results of Operations (2024 vs. 2023)

Overview

Net loss applicable to common stockholders for the year ended December 31, 2024 was approximately $79.1 million, or $0.64 per diluted share, as compared with net loss applicable to common stockholders of $48.4 million, or $0.39 per diluted share, for the year ended December 31, 2023. The increase in net loss reflects increased interest expense, net of interest income, as compared to the prior year, as well as the sale of two properties and downtime between the expiration of a few large leases during the year ended December 31, 2024, before newly executed leases commence. Additionally, we recognized approximately $4.8 million of executive separation costs during the year ended December 31, 2024.

Comparison of the accompanying consolidated statements of operations for the year ended December 31, 2024 vs. the year ended December 31, 2023.

The following table sets forth selected data from our consolidated statements of operations for the years ended December 31, 2024 and 2023, respectively, as well as each balance as a percentage of total revenues for the years presented (dollars in millions):

Revenue

Rental and tenant reimbursement revenue decreased approximately $11.2 million for the year ended December 31, 2024 as compared to the prior year. The decrease was primarily due to lost revenues during the downtime between certain large tenant expirations and the commencement or abatement expiration associated with recently executed leases, as well as the disposition of two properties in 2024. The impact of these decreases is partially offset by the roll up of rental rates and new leases commencing during the year ended December 31, 2024.

Other property related income increased approximately $3.8 million for the year ended December 31, 2024 as compared to the prior year primarily due to increased occupancy and utilization at our properties and higher transient parking at our office projects during the current period, as compared to the prior period.

Expense

Property operating costs decreased approximately $1.0 million for the year ended December 31, 2024 as compared to the prior year. The variance was primarily due to a decrease in property operating expenses associated with the sale of two properties in 2024 as well as lower property taxes associated with favorable tax assessments. These decreased costs were partially offset by higher recoverable operating expenses such as janitorial, security, repairs and maintenance and other general expenses as tenant utilization increased during the year ended December 31, 2024.

Depreciation expense increased approximately $8.5 million for the year ended December 31, 2024 compared to the prior year. The increase was primarily due to additional building and tenant improvements acquired and/or placed in service subsequent to January 1, 2023.

Amortization expense decreased approximately $18.0 million for the year ended December 31, 2024 compared to the prior year. The decrease in amortization expense is associated with certain lease intangible assets at our existing projects becoming fully amortized subsequent to January 1, 2023.

During the year ended December 31, 2024, we recognized a non-cash impairment charge of approximately $33.8 million related to a change in hold period assumptions at certain properties in our portfolio. Two of these projects, the One Lincoln Park building and 750 West John Carpenter Freeway building were subsequently sold during the year ended December 31, 2024. During the year ended December 31, 2023, we reduced the carrying amount of goodwill resulting in the recognition of non-cash impairment charges of approximately $29.4 million. See Note 6 to our accompanying consolidated financial statements for further details.

General and administrative expense increased approximately $6.2 million for the year ended December 31, 2024 compared to the prior year, primarily as the result of recognizing approximately $4.8 million of executive separation costs that occurred during the fourth quarter of 2024. The remainder of the increase primarily reflects increased accruals for potential performance-based compensation, largely associated with successful leasing during the year ended 2024.

Other Income (Expense)

Interest expense increased approximately $21.7 million for the year ended December 31, 2024 as compared to the prior year primarily driven by increased interest rates on floating-rate debt during the year ended December 31, 2024 as well as refinancing $1.2 billion of maturing debt at higher rates during the latter half of 2023 and first half of 2024. The increase was partially offset by a $5.9 million increase in capitalized interest associated with various redevelopment projects in progress during the year ended December 31, 2024.

Please refer to "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations (2022 vs. 2021)" in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 20, 2024, for a discussion of the results of operations for the year ended December 31, 2023 as compared to the year ended December 31, 2022.

Issuer and Guarantor Financial Information

As of December 31, 2024, Piedmont, through its wholly-owned subsidiary Piedmont OP, had four separate issuances totaling approximately $1.6 billion of senior unsecured notes payable outstanding that mature in 2028, 2029, 2030 and 2032 (see Note 3 to our accompanying consolidated financial statements for additional details regarding each of these issuances) (collectively, the "Notes"). The Notes are senior unsecured obligations of Piedmont OP, 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, the parent entity that consolidates Piedmont OP and all other subsidiaries. In particular, Piedmont 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; interest on overdue principal and interest on any overdue interest, if any, on the Notes will also be paid in full when due; and all other obligations of the Issuer to the holders of the Notes will be promptly paid in full. Piedmont's guarantee of the Notes is its senior unsecured obligation and ranks equally in right of payment with all of Piedmont's other existing and future senior unsecured indebtedness and guarantees. Piedmont’s guarantee of the Notes is effectively subordinated in right of payment to any future mortgage or other secured indebtedness or secured guarantees of Piedmont (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 Piedmont’s subsidiaries.

In the event of the bankruptcy, liquidation, reorganization or other winding up of Piedmont OP or Piedmont, 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.

All non-guarantor subsidiaries 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.

Pursuant to Rule 13-01 of Regulation S-X, Guarantors and Issuers of Guaranteed Securities Registered or Being Registered, the following tables present summarized financial information for Piedmont OP as issuer and Piedmont as guarantor on a combined basis after elimination of (i) intercompany transactions and balances among Piedmont OP and Piedmont and (ii) equity in earnings from and investments in any subsidiary that is a non-guarantor (in thousands):

Net Operating Income by Geographic Segment

Our President and Chief Executive Officer is our chief operating decision maker ("CODM"), who evaluates our portfolio and assesses the ongoing operations and performance of our projects utilizing the following geographic segments: Atlanta, Dallas, Orlando, Northern Virginia/Washington, D.C., Minneapolis, New York, and Boston. These operating segments are also our reportable segments. Additionally, as of December 31, 2024, we owned two properties in Houston that did 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, and we do not maintain a significant presence or anticipate further investment in

this market. These two properties are included in "Other" below. See Note 14 to the accompanying consolidated financial statements for additional information and a reconciliation of Net income/(loss) applicable to Piedmont to Net Operating Income ("NOI").

The following table presents accrual-basis NOI by geographic segment (in thousands):

Comparison of the Year Ended December 31, 2024 Versus the Year Ended December 31, 2023

Atlanta

NOI increased due to several large leases commencing at our Galleria on the Park and 999 Peachtree Street projects during the year ended December 31, 2024 as compared to the same period in the prior year.

Dallas

NOI decreased due to the sales of the One Lincoln Park and 750 West John Carpenter Freeway assets during the year ended December 31, 2024, as compared to the same period in the prior year.

Orlando

NOI decreased primarily due to the expiration of the lease associated with the sole tenant at 501 West Church. The entire building has been re-leased to another tenant; however, the new lease is not expected to commence until late 2025.

Northern Virginia/Washington, D.C.

NOI decreased primarily due to the termination of two leases at the Arlington Gateway project during the year ended December 31, 2024, as compared to the same period in the prior year.

Minneapolis

NOI decreased primarily due to the expiration of the leases associated with the sole tenants at two projects: 9320 Excelsior Boulevard and Meridian. Both projects have been designated as redevelopment assets during the year ended December 31, 2024.

Boston

NOI increased during the year ended December 31, 2024 as compared to the prior year due to a tenant's expansion at our Wayside Office Park project in the latter half of 2023.

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

Net income/(loss) 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/(loss). 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.

We calculate FFO in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as Net income/(loss) (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets, goodwill, and investment in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity, along with appropriate adjustments to those reconciling items for joint ventures, if any. 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 early 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/(loss) 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 then adding back non-cash items including: non-real estate depreciation, straight-lined rents and fair value lease adjustments, non-cash components of interest expense and compensation expense, and by making similar adjustments for joint ventures, if any. AFFO is a non-GAAP financial measure and should not be viewed as an alternative to net income/(loss) 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.

Reconciliations of net income/(loss) to FFO, Core FFO, and AFFO for the years ended December 31, 2024, 2023, and 2022, respectively, are presented below (in thousands except per share amounts):

(1)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.

(2)Includes potential dilution under the treasury stock method that would occur if our remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Such shares are not included when calculating net loss per share applicable to Piedmont for the years ended December 31, 2024 and 2023 as they would reduce the loss per share presented.

(3)Core FFO was $1.49 per diluted share for the year ended December 31, 2024, as compared to $1.74 per diluted share for the year ended December 31, 2023. Approximately $0.17 of the decrease is due to increased interest expense, net of interest income, with the remaining decrease attributable to a combination of the sale of two properties during 2024, as well as downtime between the expiration of a few large leases during the year ended December 31, 2024, before newly executed leases commence.

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/(loss) (calculated in accordance with GAAP) before adjusting for interest, depreciation and amortization and removing any impairments and 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. For Property NOI (cash basis), the effects of the reversal of the non-cash general reserve for uncollectible accounts, 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/(loss) 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; and (ii) that were not out of service for development or redevelopment during those periods. 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/(loss) 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.

The following table sets forth a reconciliation from net income/(loss) calculated in accordance with GAAP to EBITDAre, Core EBITDA, Property NOI, and Same Store NOI on both a cash and accrual basis, for the years ended December 31, 2024 and 2023, respectively (in thousands):

(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, if any. 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.

(2)We calculate Core Earnings Before Interest, Taxes, Depreciation, and Amortization ("Core EBITDA") as net income (computed in accordance with GAAP) before interest, 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. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of our operating performance. 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. Other REITs may not define Core EBITDA in the same manner as us; therefore, our computation of Core EBITDA may not be comparable to that of other REITs.

Overview

Our portfolio consists of office projects located within identified growth submarkets in large metropolitan cities concentrated primarily in the Sunbelt. We typically lease space to creditworthy corporate or governmental tenants on a long-term basis. As of December 31, 2024, our average lease was approximately 14,000 square feet with six years of lease term remaining. 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

The leased percentage of our in-service portfolio increased to 88.4% leased as of December 31, 2024, from 87.1% leased as of December 31, 2023. During the year ended December 31, 2024, we completed approximately 2.4 million square feet of leasing, including approximately a million square feet of new tenant leases which contributed to the increase in our in-service leased percentage as compared to December 31, 2023. As of December 31, 2024, scheduled lease expirations for the portfolio for the next twelve months represent less than 9% of our ALR, some portion of which have already renewed. To the extent the square footage from new leases for currently vacant space in our in-service portfolio exceeds or falls short of the square footage associated with non-renewing expirations, such leases would increase or decrease our in-service leased percentage, respectively. As of December 31, 2024, three projects, 222 South Orange Avenue in Orlando, Florida, and 9320 Excelsior Boulevard and Meridian, both in suburban Minneapolis, Minnesota, were classified as out of service as they undergo redevelopment.

Impact of Downtime, Abatement Periods, and Rental Rate Changes

Commencement of a lease associated with a new tenant 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 for both new and renewing tenants often contain upfront rental and/or operating expense abatement periods which delay the cash flow benefits of the lease even after the new or renewed lease has commenced, negatively impacting Property NOI and Same Store NOI on a cash basis until such abatements expire. As of December 31, 2024, we had approximately 1.4 million square feet of executed leases for vacant space yet to commence or under rental abatement, representing approximately $46 million of future additional annual cash rents.

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 discussed above, our diverse portfolio and the magnitude of some of our tenants' leased spaces can result in rent roll ups and roll downs that can fluctuate widely on a project-by-project and a quarter-to-quarter basis. During the year ended December 31, 2024, we experienced a 11.9% and 18.9% roll up in cash and accrual rents, respectively, on executed leases related to space vacant one year or less.

Table of Contents

Index to Financial Statements

During the year ended December 31, 2024, Same Store NOI increased by 2.6% and 1.6% on a cash and accrual basis, respectively, as newly commenced leases or those with expiring abatements outweighed expiring leases. 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/(loss) 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 ("TRS"). Our TRS performs non-customary services for tenants of buildings that we own, including real estate and non-real estate related-services. Any earnings related to such services performed by our TRS are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, our investments in TRS 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 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.

Application of Critical Accounting Estimates

Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments 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 judgment 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. The critical accounting policies outlined below have been discussed with members of the Audit Committee of the board of directors.

We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate and intangible assets of operating properties in which we have an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, we assess whether the respective carrying values will be recovered from the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition for assets held for use, or from the estimated fair value, less costs to sell, for assets held for sale. In the event that the expected undiscounted future cash flows for assets held for use or the estimated fair value, less costs to sell, for assets held for sale do not exceed the respective asset carrying value, we adjust such assets to the respective estimated fair values and recognize an impairment loss.

Projections of expected future cash flows require that we estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. The changing of these assumptions and the subjectivity of assumptions used in the future cash flow analysis, including capitalization and discount rates, could result in a changed assessment or an incorrect assessment of the property’s estimated fair value and, therefore, could result in the

misstatement of the carrying value of our real estate and related intangible assets and our reported net income/(loss) attributable to Piedmont.

Valuation of Goodwill

Goodwill is the excess of cost of an acquired entity over the amounts specifically assigned to assets acquired and liabilities assumed in purchase accounting for business combinations, and is allocated to each of our reporting units. We test the carrying value of the goodwill assigned to each of our reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit may be less than its carrying value. Such interim circumstances may include, but are not limited to, significant adverse changes in legal factors or in the general business climate, adverse action or assessment by a regulator, unanticipated competition, the loss of key personnel, or persistent declines in an entity’s stock price below the carrying value of the entity.

In performing our goodwill impairment assessment, we compare the estimated fair value of each of our reporting units to the reporting unit's carrying value, inclusive of allocated goodwill. If we conclude the fair value of a reporting unit is less than its carrying value, then we would recognize a goodwill impairment loss equal to the excess of the reporting unit's carrying amount over its estimated fair value (not to exceed the total goodwill allocated to that reporting unit). Estimation of the fair value of each reporting unit involves projections of discounted future cash flows, which are derived using certain assumptions that are subjective in nature. We also make estimates about future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, and the number of months it takes to re-lease the property, among other factors. The changing of these assumptions and the subjectivity of the market based assumptions used in the discounted future cash flow analysis, particularly the capitalization rates and discount rates, could result in a changed assessment or an incorrect assessment of the reporting unit’s estimated fair value and, therefore, could result in the misstatement of the carrying value of our reporting units and related goodwill and our reported net income/(loss) attributable to Piedmont. In addition, adverse economic conditions could also cause us to recognize additional asset impairment charges in the future, which could materially and adversely affect our business, financial condition and results of operations. See Note 2 and Note 6 to our accompanying consolidated financial statements for more details regarding our goodwill.

Rental Revenue Recognition

Rental income for office properties is our principal source of revenue. The timing of rental revenue recognition is largely dependent on our conclusion as to whether we, or our tenant, are the owner of tenant improvements at the leased property. The determination of whether we, or our tenant, are the owner of tenant improvements for accounting purposes is subject to significant judgment. In making that determination, we consider numerous factors and perform an evaluation of each individual lease. No one factor is determinative in reaching a conclusion. The factors we evaluate include but are not limited to the following:

•whether the tenant is obligated by the terms of the lease agreement to construct or install the leasehold improvements as a condition of the lease;

•whether the landlord can require the lessee to make specified improvements or otherwise enforce its economic rights to those assets;

•whether the tenant is required to provide the landlord with documentation supporting the cost of tenant improvements prior to reimbursement by the landlord;

•whether the landlord is obligated to fund cost overruns for the construction of leasehold improvements;

•whether the leasehold improvements are unique to the tenant or could reasonably be used by other parties; and

•whether the estimated economic life of the leasehold improvements is long enough to allow for a significant residual value that could benefit the landlord at the end of the lease term.

When we conclude that we are the owner of tenant improvements, we record the cost to construct the tenant improvements as an asset and commence rental revenue recognition when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as our asset are substantially complete, and our landlord obligation has been materially satisfied. When we conclude that our tenant is the owner of certain tenant improvements, we record our contribution towards those improvements as a lease incentive, which is amortized as a reduction to rental and tenant reimbursement revenue on a straight-line basis over the term of the related lease, and the recognition of rental revenue begins when the tenant takes possession of or controls the space.

In addition, we also record the cost of certain tenant improvements paid for or reimbursed by tenants when we conclude that we are the owner of such tenant improvements using the factors discussed above. For these tenant-funded tenant improvements, we record the amount funded or reimbursed by tenants as an asset and deferred revenue. The asset is depreciated and the deferred

45

revenue is amortized and recognized as rental revenue over the term of the related lease beginning upon substantial completion of the leased premises. Consequently, our determination as to whether we, or our tenant, are the owner of tenant improvements for accounting purposes has a significant impact on both the amount and timing of rental revenue that we record related to tenant-funded tenant improvements.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2023 and 2022, and for the years ended December 31, 2023, 2022, and 2021, included elsewhere in this Annual Report on Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements” preceding Part I of this report and “Risk Factors" set forth in Item 1A. of this report.

Liquidity and Capital Resources

We intend to use cash on hand, cash flow 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. As a result of refinancing activity completed in January 2024 (see Note 3 to our accompanying consolidated financial statements), our only remaining 2024 debt maturity is the $50.2 million outstanding balance of our $400 Million Unsecured Senior Notes due in March 2024, which we intend to repay using our $600 Million Unsecured 2022 Line of Credit. Our 2025 debt maturities are the remaining $25 million of our $215 Million Unsecured 2023 Term Loan due in January 2025 and the $250 Million Unsecured 2018 Term Loan due in March 2025. We currently anticipate repaying these amounts using any or a combination of following: our $600 Million Unsecured 2022 Line of Credit, net proceeds from the disposition of select properties, and other new secured or unsecured borrowings from third party lenders or the public debt market. The nature and timing of any 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.

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 years ended December 31, 2023 and 2022, we incurred the following types of capital expenditures (in thousands):

(1)Of the total amounts paid, approximately $10.1 million and $7.2 million related to soft costs such as capitalized interest, payroll, and other general and administrative expenses for the year ended December 31, 2023 and 2022, respectively.

"Capital expenditures for redevelopment/renovations" during the years ended December 31, 2023 and 2022 primarily 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 Galleria Tower buildings in Dallas, Texas, as well as our 222 South Orange building in Orlando, Florida, and our Galleria on the Park buildings, 1155 Perimeter Center West, and 999 Peachtree Street in Atlanta, Georgia, among others.

"Other capital expenditures, including building and tenant improvements" include all other capital expenditures during the respective period and are typically comprised of tenant and building improvements necessary to lease, maintain, or provide enhancements, including energy efficient equipment to our existing portfolio of office properties.

We currently do not anticipate incurring any unusually large or material capital expenditures within any given year in order to meet recognized sustainable development standards, and achieve our environmental impact goals.

Given that our operating model frequently results in leases for multiple blocks of space to credit-worthy tenants, our leasing success can result in capital outlays which vary from one reporting period to another based upon the specific leases executed. For leases executed during the year ended December 31, 2023, we have committed to spend approximately $5.22 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as compared to $5.34 (net of expired lease commitments) for the year ended December 31, 2022. As of December 31, 2023, we had one individually significant unrecorded tenant allowance commitment greater than $10.0 million.

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

33

due to a number of factors and are highly dependent on the size of the leased square footage, length of lease term, and the competitive market conditions of the particular office market at the time a lease is being negotiated.

Although repayment of debt is currently our priority, 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 also use capital resources to pay dividends to our stockholders. Given the significant increase in interest expense during the year ended December 31, 2023 (see Results of Operations below), we reduced our annual dividend from $0.84 per share to $0.50 per share beginning with the third quarter of 2023 which will reduce the cash used to pay the dividend by approximately $40 million on an annual basis. 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, including to pay dividends to our stockholders.

Results of Operations (2023 vs. 2022)

Overview

Net loss applicable to common stockholders for the year ended December 31, 2023 was approximately $48.4 million, or $0.39 per diluted share, as compared with net income applicable to common stockholders of $146.8 million, or $1.19 per diluted share, for the year ended December 31, 2022. The decrease in net income reflects: (i) a decreased gain on sale of real estate assets of $149.8 million; (ii) a $35.6 million increase in interest expense in the current period compared to the prior period primarily due to higher interest rates; (iii) and a $14.8 million increase in depreciation expense due to additional building and tenant improvements acquired and/or placed in service over the two year period. These decreases were partially offset by continued growth in Property Net Operating Income during the year ended December 31, 2023, as compared to the year ended December 31, 2022.

Comparison of the accompanying consolidated statements of operations for the year ended December 31, 2023 vs. the year ended December 31, 2022.

The following table sets forth selected data from our consolidated statements of operations for the years ended December 31, 2023 and 2022, respectively, as well as each balance as a percentage of total revenues for the years presented (dollars in millions):

Revenue

Rental and tenant reimbursement revenue increased approximately $9.6 million for the year ended December 31, 2023 as compared to the prior year. The increase was primarily due to capital recycling activity during the year ended December 31, 2022 and higher tenant reimbursements as a result of higher recoverable operating expenses during the current year as tenant utilization of our buildings increased during 2023 as compared to the prior year.

Other property related income increased approximately $4.3 million for the year ended December 31, 2023 as compared to the prior year primarily due to higher transient parking at our buildings during the current year. Additionally, parking revenue associated with the 1180 Peachtree Street building acquired during the third quarter of 2022 also contributed to the increase.

35

Index to Financial Statements

Expense

Property operating costs increased approximately $9.0 million for the year ended December 31, 2023 as compared to the prior year. The variance was primarily due to higher recoverable operating expenses such as janitorial, security, and utilities resulting from higher tenant utilization during the current period, and capital recycling activity during the year ended December 31, 2022.

Depreciation expense increased approximately $14.8 million for the year ended December 31, 2023 compared to the prior year. The increase was primarily due to additional building and tenant improvements acquired and/or placed in service subsequent to January 1, 2022, as well as the acquisition of 1180 Peachtree Street mentioned above.

Amortization expense decreased approximately $3.2 million for the year ended December 31, 2023 compared to the prior year. The decrease in amortization expense associated with certain lease intangible assets at our existing properties becoming fully amortized subsequent to January 1, 2022 was largely offset by additional amortization associated with the acquisition of 1180 Peachtree Street mentioned above, as well as accelerated amortization associated with lease terminations.

During the years ended December 31, 2023 and 2022, we reduced the carrying amount of goodwill resulting in the recognition of non-cash impairment charges of approximately $29.4 million and $16.0 millions, respectively. See Note 6 to our accompanying consolidated financial statements for further details. During the year ended December 31, 2022, we also recognized a non-cash impairment loss on real estate assets of approximately $10.0 million related to a change in hold period assumptions for one of our Minneapolis properties.

Other Income (Expense)

Interest expense increased approximately $35.6 million for the year ended December 31, 2023 as compared to the prior year primarily driven by increased interest rates on floating-rate debt during 2023 and on $600 million of refinanced fixed-rate debt, also obtained in 2023.

Other income increased approximately $1.2 million for the year ended December 31, 2023 as compared to the prior year due primarily to interest income earned on cash invested for short periods pending the repayment of debt; consequently, we do not expect such interest income to recur in future periods.

The loss on early extinguishment of debt for the year ended December 31, 2023 is comprised of the pro-rata write-off of unamortized debt issuance costs and discounts associated with the early repurchase of approximately $350 million aggregate principal amount of the $400 Million Unsecured Senior Notes due 2024, as well as fees paid. See Note 3 to our accompanying consolidated financial statements for further details.

Gain on sale of real estate assets during the year ended December 31, 2022 includes $49.2 million of gain recognized on the sale of the 225 & 235 Presidential Way buildings, which closed in January 2022, as well as $102.5 million of gain recognized on the sale of the Cambridge Portfolio in December 2022.

Results of Operations (2022 vs. 2021)

Please refer to "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations (2022 vs. 2021)" in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on February 22, 2023, for a discussion of the results of operations for the year ended December 31, 2022 as compared to the year ended December 31, 2021.

Issuer and Guarantor Financial Information

As of December 31, 2023, Piedmont, through its wholly-owned subsidiary Piedmont OP, had four separate issuances totaling approximately $1.3 billion of senior unsecured notes payable outstanding that mature in 2024, 2028, 2030 and 2032 (see Note 3 to our accompanying consolidated financial statements for additional details regarding each of these issuances) (collectively, the "Notes"). The Notes are senior unsecured obligations of Piedmont OP, 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, the parent entity that consolidates Piedmont OP and all other subsidiaries. In particular, Piedmont guarantees to each holder of the Notes that the principal and interest will be paid in full when due, whether at the maturity dates of the respective loans, or upon acceleration, upon redemption, or otherwise; interest on overdue principal and interest on any overdue interest, if any, will also be paid in full when due; and all other obligations of the Issuer to the holders of the Notes will be promptly paid in full. Piedmont's guarantee of the Notes is its senior unsecured obligation and ranks equally in right of payment with all of Piedmont's other existing and future senior unsecured indebtedness and guarantees. Piedmont’s guarantee of the Notes is effectively subordinated in right of payment to any future mortgage or other secured indebtedness or secured guarantees of Piedmont (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 Piedmont’s subsidiaries.

In the event of the bankruptcy, liquidation, reorganization or other winding up of Piedmont OP or Piedmont, 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.

All non-guarantor subsidiaries 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.

Pursuant to Rule 13-01 of Regulation S-X, Guarantors and Issuers of Guaranteed Securities Registered or Being Registered, the following tables present summarized financial information for Piedmont OP as issuer and Piedmont as guarantor on a combined basis after elimination of (i) intercompany transactions and balances among Piedmont OP and Piedmont and (ii) equity in earnings from and investments in any subsidiary that is a non-guarantor (in thousands):

Net Operating Income by Geographic Segment

Our President and Chief Executive Officer is our chief operating decision maker ("CODM") who evaluates our portfolio and assesses the ongoing operations and performance of our properties utilizing the following geographic segments: Atlanta, Dallas, Orlando, Northern Virginia/Washington, D.C., Minneapolis, New York, and Boston. These operating segments are also our reportable segments. Additionally, as of December 31, 2023, we owned two properties in Houston that did 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, and we do not maintain a significant presence or anticipate further investment in this market. These two properties are included in "Other" below. See Note 14 to the accompanying consolidated financial statements for additional information and a reconciliation of Net income/(loss) applicable to Piedmont to Net Operating Income ("NOI").

The following table presents accrual-basis NOI by geographic segment (in thousands):

Comparison of the Year Ended December 31, 2023 Versus the Year Ended December 31, 2022

Atlanta

NOI increased primarily due to the acquisition of 1180 Peachtree Street during the third quarter of 2022.

Northern Virginia/Washington, D.C.

NOI decreased due to the termination of certain leases at Arlington Gateway in late 2022.

Boston

NOI decreased primarily due to the disposition of the 225 and 235 Presidential Way assets in January 2022 and the disposition of the Cambridge Portfolio in December 2022.

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

Net income/(loss) 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/(loss). 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.

We calculate FFO in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as Net income/(loss) (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets, goodwill, and investment in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity, along with appropriate adjustments to those reconciling items for joint ventures, if any. 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 early 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/(loss) 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 then adding back non-cash items including: non-real estate depreciation, straight-lined rents and fair value lease adjustments, non-cash components of interest expense and compensation expense, and by making similar adjustments for joint ventures, if any. AFFO is a non-GAAP financial measure and should not be viewed as an alternative to net income/(loss) 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.

Reconciliations of net income/(loss) to FFO, Core FFO, and AFFO for the years ended December 31, 2023, 2022, and 2021, respectively, are presented below (in thousands except per share amounts):

(1)Based on weighted-average shares outstanding—diluted.

(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.

(3)Includes potential dilution under the treasury stock method that would occur if our remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Such shares are not included when calculating net loss per diluted share applicable to Piedmont for the years ended December 31, 2023 and 2021 as they would reduce the loss per share presented.

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/(loss) (calculated in accordance with GAAP) before adjusting for interest, depreciation and amortization and removing any impairments and 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. For Property NOI (cash basis), the effects of non-cash general reserve for uncollectible accounts, 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/(loss) 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; and (ii) that were not out of service for development or redevelopment during those periods. 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/(loss) 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.

The following table sets forth a reconciliation from net income/(loss) calculated in accordance with GAAP to EBITDAre, Core EBITDA, Property NOI, and Same Store NOI on both a cash and accrual basis, for the years ended December 31, 2023 and 2022, respectively (in thousands):

(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, if any. 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.

(2)We calculate Core Earnings Before Interest, Taxes, Depreciation, and Amortization ("Core EBITDA") as net income (computed in accordance with GAAP) before interest, 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. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of our operating performance. 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. Other REITs may not define Core EBITDA in the same manner as us; therefore, our computation of Core EBITDA may not be comparable to that of other REITs.

(6)Other investments consist of active redevelopment and development projects, land, and recently completed redevelopment and development projects for which some portion of operating expenses were capitalized during the current and/or prior year reporting periods.

Overview

Our portfolio consists of office properties located within identified growth submarkets in large metropolitan cities concentrated primarily in the Sunbelt. We typically lease space to creditworthy corporate or governmental tenants on a long-term basis. As of December 31, 2023, our average lease was approximately 15,000 square feet with approximately six years of lease term remaining. 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

The leased percentage of our portfolio increased approximately 40 basis points during the year ended December 31, 2023, from 86.7% leased as of December 31, 2022 to 87.1% leased as of December 31, 2023. The increase was attributable to the completion of approximately 830,000 of new tenant leases during the year ended December 31, 2023, representing the largest annual amount of new tenant leasing since 2018. Additionally, we renewed approximately 1.4 million square feet of expiring leases, resulting in approximately 2.2 million square feet of total leasing for the year ended December 31, 2023. Scheduled lease expirations for 2024 represent approximately 1.2 million square feet, or 7.4% of our ALR, some portion of which may renew. Our historical retention rate is approximately 68% over the past five years. To the extent the square footage from new leases for currently vacant space exceeds or falls short of the square footage associated with non-renewing expirations, such leases would increase or decrease our overall leased percentage, respectively.

Impact of Downtime, Abatement Periods, and Rental Rate Changes

Commencement of a lease associated with a new tenant 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 for both new and renewing tenants often contain upfront rental and/or operating expense abatement periods which delay the cash flow benefits of the lease even after the new or renewed lease has commenced, negatively impacting Property NOI and Same Store NOI on a cash basis until such abatements expire. As of December 31, 2023, we had approximately 1.1 million square feet of executed leases for vacant space yet to commence or under rental abatement, representing approximately $35 million of future additional annual cash rents.

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 diverse portfolio and the magnitude of some of our tenants' leased spaces 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 year ended December 31, 2023, we

43

experienced a 4.7% and 12.4% roll up in cash and accrual rents, respectively, on executed leases related to space vacant one year or less.

During the year ended December 31, 2023, Same Store NOI increased by 2.2% on a cash basis and decreased 1.0% on an accrual basis as compared to the prior year. Cash basis Same Store NOI increased as compared to the prior year primarily due to rental rate roll-ups, as well as new leases commencing or leases with expiring rental or operating expense abatements beginning to outweigh leases that expired during 2023. Property Net Operating Income on an accrual basis increased approximately $4.8 million, or 1.4%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022, primarily as a result of the acquisition of 1180 Peachtree Street during the third quarter of 2022. After removing the operating results of 1180 Peachtree Street, Same Store NOI on an accrual basis for the year ended December 31, 2023 decreased approximately 1% as compared to the prior year. 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/(loss) 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 ("TRS"). Our TRS performs non-customary services for tenants of buildings that we own, including real estate and non-real estate related-services. Any earnings related to such services performed by our TRS are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, our investments in TRS 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 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.

Application of Critical Accounting Estimates

Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments 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 judgment 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. The critical accounting policies outlined below have been discussed with members of the Audit Committee of the board of directors.

Valuation of Real Estate Assets

We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate and intangible assets of operating properties in which we have an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, we assess whether the respective carrying values will be recovered from the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition for assets held for use, or from the estimated fair value, less costs to sell, for assets held for sale. In the event that the expected undiscounted future cash flows for assets held for use or the estimated fair value, less costs to sell, for

44

Table of Contents

Index to Financial Statements

assets held for sale do not exceed the respective asset carrying value, we adjust such assets to the respective estimated fair values and recognize an impairment loss.

Projections of expected future cash flows require that we estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. The changing of these assumptions and the subjectivity of assumptions used in the future cash flow analysis, including capitalization and discount rates, could result in a changed assessment or an incorrect assessment of the property’s estimated fair value and, therefore, could result in the misstatement of the carrying value of our real estate and related intangible assets and our reported net income/(loss) attributable to Piedmont.

Valuation of Goodwill

Goodwill is the excess of cost of an acquired entity over the amounts specifically assigned to assets acquired and liabilities assumed in purchase accounting for business combinations, and is allocated to each of our reporting units. We test the carrying value of the goodwill assigned to each of our reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit may be less than its carrying value. Such interim circumstances may include, but are not limited to, significant adverse changes in legal factors or in the general business climate, adverse action or assessment by a regulator, unanticipated competition, the loss of key personnel, or persistent declines in an entity’s stock price below the carrying value of the entity.

In performing our goodwill impairment assessment, we compare the estimated fair value of each of our reporting units to the reporting unit's carrying value, inclusive of allocated goodwill. If we conclude the fair value of a reporting unit is less than its carrying value, then we would recognize a goodwill impairment loss equal to the excess of the reporting unit's carrying amount over its estimated fair value (not to exceed the total goodwill allocated to that reporting unit). Estimation of the fair value of each reporting unit involves projections of discounted future cash flows, which are derived using certain assumptions that are subjective in nature. We also make estimates about future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, and the number of months it takes to re-lease the property, among other factors. The changing of these assumptions and the subjectivity of the market based assumptions used in the discounted future cash flow analysis, particularly the capitalization rates and discount rates, could result in a changed assessment or an incorrect assessment of the reporting unit’s estimated fair value and, therefore, could result in the misstatement of the carrying value of our reporting units and related goodwill and our reported net income/(loss) attributable to Piedmont. In addition, adverse economic conditions could also cause us to recognize additional asset impairment charges in the future, which could materially and adversely affect our business, financial condition and results of operations. See Note 6 to our accompanying consolidated financial statements for more details regarding our goodwill for the years ended December 31, 2023 and 2022.

Rental Revenue Recognition

Rental income for office properties is our principal source of revenue. The timing of rental revenue recognition is largely dependent on our conclusion as to whether we, or our tenant, are the owner of tenant improvements at the leased property. The determination of whether we, or our tenant, are the owner of tenant improvements for accounting purposes is subject to significant judgment. In making that determination, we consider numerous factors and perform an evaluation of each individual lease. No one factor is determinative in reaching a conclusion. The factors we evaluate include but are not limited to the following:

•whether the tenant is obligated by the terms of the lease agreement to construct or install the leasehold improvements as a condition of the lease;

•whether the landlord can require the lessee to make specified improvements or otherwise enforce its economic rights to those assets;

•whether the tenant is required to provide the landlord with documentation supporting the cost of tenant improvements prior to reimbursement by the landlord;

•whether the landlord is obligated to fund cost overruns for the construction of leasehold improvements;

•whether the leasehold improvements are unique to the tenant or could reasonably be used by other parties; and

•whether the estimated economic life of the leasehold improvements is long enough to allow for a significant residual value that could benefit the landlord at the end of the lease term.

When we conclude that we are the owner of tenant improvements, we record the cost to construct the tenant improvements as an asset and commence rental revenue recognition when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as our asset are substantially complete, and our landlord obligation has been

45

Table of Contents

Index to Financial Statements

materially satisfied. When we conclude that our tenant is the owner of certain tenant improvements, we record our contribution towards those improvements as a lease incentive, which is amortized as a reduction to rental and tenant reimbursement revenue on a straight-line basis over the term of the related lease, and the recognition of rental revenue begins when the tenant takes possession of or controls the space.

In addition, we also record the cost of certain tenant improvements paid for or reimbursed by tenants when we conclude that we are the owner of such tenant improvements using the factors discussed above. For these tenant-funded tenant improvements, we record the amount funded or reimbursed by tenants as an asset and deferred revenue. The asset is depreciated and the deferred revenue is amortized and recognized as rental revenue over the term of the related lease beginning upon substantial completion of the leased premises. Consequently, our determination as to whether we, or our tenant, are the owner of tenant improvements for accounting purposes has a significant impact on both the amount and timing of rental revenue that we record related to tenant-funded tenant improvements.

Related-Party Transactions and Agreements

There were no related-party transactions during the three years ended December 31, 2023.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2022 and 2021, and for the years ended December 31, 2022, 2021, and 2020, included elsewhere in this Annual Report on Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements” preceding Part I of this report and “Risk Factors" set forth in Item 1A. of this report.

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. In addition, on January 31, 2023, we entered into a new $215 million, floating-rate, unsecured term loan facility, the proceeds from which we intend to use to repay the majority of our $350 Million Unsecured Senior Notes that mature on June 1, 2023. The remaining balance of the $350 Million Unsecured Senior Notes due 2023 will be repaid from a combination of cash on hand, proceeds from select property dispositions and/or borrowings under our $600 Million Unsecured 2022 Line of Credit. 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. As of December 31, 2022, we had the full $600 million of capacity available under our $600 Million Unsecured 2022 Line of Credit, and we believe that we have sufficient liquidity to meet our obligations for the foreseeable future.

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 years ended December 31, 2022 and 2021, we incurred the following types of capital expenditures (in thousands):

(1)Of the total amounts paid, approximately $7.2 million and $6.3 million related to soft costs such as capitalized interest, payroll, and other general and administrative expenses for the year ended December 31, 2022 and 2021, respectively.

"Capital expenditures for redevelopment/renovations" during the years ended December 31, 2022 and 2021 primarily 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 Galleria Tower buildings in Dallas, Texas; as well as our Galleria buildings and 999 Peachtree Street in Atlanta, Georgia, among others.

"Other capital expenditures, including building and tenant improvements" include all other capital expenditures during the respective period and are typically comprised of tenant and building improvements necessary to lease, maintain, or provide enhancements, including energy efficient equipment to our existing portfolio of office properties. We currently do not anticipate incurring any unusually large or material capital expenditures within any given year in order to meet recognized sustainable development standards, and achieve our environmental impact goals.

Given that our operating model frequently results in leases for multiple blocks of space to credit-worthy tenants, our leasing success can result in capital outlays which vary from one reporting period to another based upon the specific leases executed. For example, for leases executed during the year ended December 31, 2022, we committed to spend approximately $5.34 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as compared to $4.25 (net of expired lease commitments) for the year ended December 31, 2021. Commitments per square foot per year of lease term for tenant improvement allowances and lease commissions for the year ended December 31, 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.

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

33

Table of Contents

Index to Financial Statements

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 such purposes would be a prudent use of capital. As of December 31, 2022, we had approximately $150.5 million of board-authorized share repurchase capacity under the program which may be used for share repurchases through February 2024. Finally, other than our $350 Million Unsecured Senior Notes due 2023 discussed above, we have no other debt maturing until 2024; however, we may use capital to repay debt obligations when we deem it prudent to refinance various obligations.

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 (2022 vs. 2021)

Overview

Piedmont recognized net income applicable to common stockholders for the year ended December 31, 2022 of $146.8 million, or $1.19 per diluted share, as compared with net loss applicable to common stockholders of $1.2 million, or $0.01 per diluted share, for the year ended December 31, 2021. The year ended December 31, 2022 included approximately $151.7 million of gain on the sales of real estate assets as well as increased revenues due to rental rate increases across the portfolio, offset by $26.0 million in non-cash impairment charges related to reductions in our carrying value of goodwill and one real estate asset. The year ended December 31, 2021 included a $41.0 million non-cash impairment charge related to the subsequent sale of our last remaining Chicago asset (see Note 7 to our accompanying consolidated financial statements).

Comparison of the accompanying consolidated statements of operations for the year ended December 31, 2022 vs. the year ended December 31, 2021.

The following table sets forth selected data from our consolidated statements of operations for the years ended December 31, 2022 and 2021, respectively, as well as each balance as a percentage of total revenues for the years presented (dollars in millions):

Revenue

Rental and tenant reimbursement revenue increased approximately $31.1 million for the year ended December 31, 2022 as compared to the prior year. The increase was primarily due to capital recycling activity subsequent to January 1, 2021, 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 year.

Property management fee revenue decreased approximately $0.8 million for the year ended December 31, 2022 as compared to the prior year. Such fees fluctuate from period to period due to the variability of construction activity as well as the commencement or termination of property management agreements we may enter into with unrelated third-party owners. During the year ended December 31, 2022, one multi-year property management agreement with a third-party terminated in Chicago, Illinois.

Other property related income increased approximately $4.8 million for the year ended December 31, 2022 as compared to the prior year primarily due to higher transient parking at our buildings during the current year, as compared to the prior year, and additional parking revenue associated with properties acquired subsequent to January 1, 2021.

35

Index to Financial Statements

Expense

Property operating costs increased approximately $15.2 million for the year ended December 31, 2022 as compared to the prior year. The variance was primarily due to higher recoverable operating expenses such as janitorial, security, and utilities resulting from higher tenant utilization during the current period, and capital recycling activity subsequent to January 1, 2021.

Depreciation expense increased approximately $13.0 million for the year ended December 31, 2022 compared to the prior year. The increase was primarily due to additional building and tenant improvements acquired and/or placed in service subsequent to January 1, 2021.

Amortization expense increased approximately $4.9 million for the year ended December 31, 2022 compared to the prior year. The increase was primarily due to additional amortization associated with property acquisitions subsequent to January 1, 2021, partially offset by certain lease intangible assets at our existing properties becoming fully amortized during the same period.

During the year ended December 31, 2022, we recognized a non-cash impairment loss on real estate assets of approximately $10.0 million related to a change in hold period assumptions for one of our Minneapolis properties. See Note 7 to our accompanying consolidated financial statements for additional details. Also, during the year ended December 31, 2022, due to the decline of the stock market and our stock price, we recognized a non-cash impairment loss related to goodwill of approximately $16.0 million for the year ended December 31, 2022. See Note 2 to our accompanying consolidated financial statements for further details. During the year ended December 31, 2021, we recognized a non-cash impairment loss on real estate assets of approximately $41.0 million related to a change in hold period assumptions for our last remaining Chicago asset, which was subsequently sold during the year ended December 31, 2022.

General and administrative expenses decreased approximately $1.2 million for the year ended December 31, 2022 as compared to the year ended December 31, 2021, primarily reflecting decreased accruals for potential performance-based compensation, partially offset by approximately $2.2 million in severance costs related to a reorganization of management during the fourth quarter of 2022.

Other Income (Expense)

Interest expense increased approximately $14.4 million for the year ended December 31, 2022 as compared to the prior year primarily driven by a higher average debt balance outstanding during the current year as a result of the purchase of the 1180 Peachtree Street building, 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 year ended December 31, 2022.

Other income decreased approximately $7.5 million for the year ended December 31, 2022 as compared to 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 year ended December 31, 2022 includes $49.2 million of gain recognized on the sale of the 225 & 235 Presidential Way buildings, which closed in January of 2022, as well as $102.6 million of gain recognized on the sale of the 1414 Massachusetts Avenue building and the One Brattle Square building in December of 2022.

Results of Operations (2021 vs. 2020)

Please refer to "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations (2021 vs. 2020)" in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 17, 2022, for a discussion of the results of operations for the year ended December 31, 2021 as compared to the year ended December 31, 2020.

Issuer and Guarantor Financial Information

Piedmont, through its wholly-owned subsidiary Piedmont OP (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, 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. In particular, 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; interest on overdue principal and interest on any overdue interest, if any, on the Notes will also be paid in full when due; 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.

All non-Guarantor subsidiaries 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.

Pursuant to Rule 13-01 of Regulation S-X, Guarantors and Issuers of Guaranteed Securities Registered or Being Registered, the following tables present summarized financial information for Piedmont OP as Issuer and Piedmont Office Realty Trust, Inc. as Guarantor on a combined basis after elimination of (i) intercompany transactions and balances among the Issuer and the Guarantor and (ii) equity in earnings from and investments in any subsidiary that is a non-Guarantor (in thousands):

Net Operating Income by Geographic Segment

Our chief operating decision maker ("CODM"), who is our President and Chief Executive Officer, evaluates our portfolio and assesses the ongoing operations and performance of our properties utilizing the following geographic segments: Atlanta, Dallas, Washington, D.C./Northern Virginia, Boston, Orlando, Minneapolis, and New York. These operating segments are also Piedmont’s reportable segments. Additionally, as of December 31, 2022, Piedmont owned two properties in Houston that did 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, and Piedmont does not maintain a significant presence or anticipate

further investment in these markets. These two properties are included in "Other" below. See Note 16 to the accompanying consolidated financial statements for additional information and a reconciliation of Net income/(loss) applicable to Piedmont to Net Operating Income ("NOI").

The following table presents accrual-basis NOI by geographic segment (in thousands):

Comparison of the Year Ended December 31, 2022 Versus the Year Ended December 31, 2021

Atlanta

NOI increased primarily due to the acquisition of 999 Peachtree Street during the fourth quarter of 2021 and 1180 Peachtree Street during the third quarter of 2022.

Dallas

NOI decreased primarily due to a contraction by a tenant at 750 West John Carpenter Freeway, as well as an expiration of a lease at One Galleria Tower during 2021.

Washington, D.C./Northern Virginia

NOI increased due to the commencement of certain leases, primarily at 400 Virginia Avenue and 3100 Clarendon Boulevard.

Boston

NOI decreased primarily due to the disposition of 225 and 235 Presidential Way in January 2022.

Other

NOI increased primarily due to the expiration of rental and operating expense abatements associated with the Transocean lease at our Enclave Place building in Houston, Texas during the second quarter of 2021.

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

Net income/(loss) 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/(loss). 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.

We calculate FFO in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as Net income/(loss) (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investment in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity, along with appropriate adjustments to those reconciling items for joint ventures, if any. 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/(loss) 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 then adding back non-cash items including: non-real estate depreciation, straight-lined rents and fair value lease adjustments, non-cash components of interest expense and compensation expense, and by making similar adjustments for joint ventures, if any. AFFO is a non-GAAP financial measure and should not be viewed as an alternative to net income/(loss) 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.

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.

(3)Includes potential dilution under the treasury stock method that would occur if our remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Such shares are not included when calculating net loss per diluted share applicable to Piedmont for the year ended December 31, 2021 as they would reduce the loss per share presented.

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/(loss) (calculated in accordance with GAAP) before adjusting for interest, depreciation and amortization and removing any impairments and 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. For Property NOI (cash basis), the effects of non-cash general reserve for uncollectible accounts, 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/(loss) 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. 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/(loss) 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.

The following table sets forth a reconciliation from net income/(loss) calculated in accordance with GAAP to EBITDAre, Core EBITDA, Property NOI, and Same Store NOI on both a cash and accrual basis, for the years ended December 31, 2022 and 2021, respectively (in thousands):

(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.

(2)We calculate Core Earnings Before Interest, Taxes, Depreciation, and Amortization ("Core EBITDA") as net income (computed in accordance with GAAP) before interest, 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. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative to net income calculated in accordance with GAAP as a measurement of our operating performance. 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. Other REITs may not define Core EBITDA in the same manner as us; therefore, our computation of Core EBITDA may not be comparable to that of other REITs.

(5)Dispositions include Two Pierce Place in Itasca, Illinois and 225 and 235 Presidential Way in Woburn, Massachusetts, all sold during the first quarter of 2022, and One Brattle Square and 1414 Massachusetts Avenue in Cambridge, Massachusetts, sold in the fourth quarter of 2022.

(6)Other investments consist of active redevelopment and development projects, land, and recently completed redevelopment and development projects for which some portion of operating expenses were capitalized during the current and/or prior year reporting periods. The operating results from 222 South Orange Avenue in Florida are included in this line item.

Overview

Our portfolio consists of office properties located within identified growth submarkets in large metropolitan cities concentrated primarily in the Sunbelt. We typically lease space to creditworthy corporate or governmental tenants on a long-term basis. As of December 31, 2022, our average lease was approximately 15,000 square feet with approximately 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 86.7% leased as of December 31, 2022, as compared to 85.5% leased as of December 31, 2021, and scheduled lease expirations for the portfolio as a whole for 2023 represent approximately 7% of our ALR, some portion of which may renew. To the extent the square footage from new leases for currently vacant space exceed or fall short of the square footage associated with non-renewing expirations, such leases would increase or decrease our overall leased percentage, respectively.

Impact of Downtime, Abatement Periods, and Rental Rate Changes

Commencement of a lease associated with a new tenant in the property 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 to new tenants and those renewing, 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 December 31, 2022, we had approximately 1.14 million square feet of executed leases for vacant space yet to commence or under rental abatement, representing approximately $33 million of additional annual cash revenue.

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 diverse portfolio and the magnitude of some of our tenants' leased spaces 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 year ended December 31, 2022, we experienced a 9.7% and 17.2% roll up in cash and accrual rents, respectively, on executed leases related to space vacant one year or less. Both increases for the year were impacted by a lease renewal and extension executed with a large tenant with an average lease term of three years at our Three Galleria Tower building in Dallas, Texas.

Same Store NOI increased by 1.9% and 1.1% on a cash and accrual basis, respectively, for the year ended December 31, 2022 as compared to the year ended December 31, 2021. The primary drivers of the increases in both metrics were increased rental rates and the expiration of abatements at certain properties. 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/(loss) 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 ("TRS"). Our TRS performs non-customary services for tenants of buildings that we own, including real estate and non-real estate related-services. Any earnings related to such services performed by our TRS are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, our investments in TRS 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 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.

Application of Critical Accounting Estimates

Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments 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 judgment 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. The critical accounting policies outlined below have been discussed with members of the Audit Committee of the board of directors.

Valuation of Real Estate Assets

We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate and intangible assets of operating properties in which we have an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, we assess whether the respective carrying values will be recovered from the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition for assets held for use, or from the estimated fair value, less costs to sell, for assets held for sale. In the event that the expected undiscounted future cash flows for assets held for use or the estimated fair value, less costs to sell, for assets held for sale do not exceed the respective asset carrying value, we adjust such assets to the respective estimated fair values and recognize an impairment loss.

Projections of expected future cash flows require that we estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. The changing of these assumptions and the subjectivity of assumptions used in the future cash flow analysis, including capitalization and discount rates, could result in a changed assessment or an incorrect assessment of the property’s estimated fair value and, therefore, could result in the

44

Table of Contents

Index to Financial Statements

misstatement of the carrying value of our real estate and related intangible assets and our reported net income/(loss) attributable to Piedmont.

Valuation of Goodwill

Goodwill is the excess of cost of an acquired entity over the amounts specifically assigned to assets acquired and liabilities assumed in purchase accounting for business combinations, and is allocated to each of our reporting units. We test the carrying value of the goodwill assigned to each of our reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit may be less than its carrying value. Such interim circumstances may include, but are not limited to, significant adverse changes in legal factors or in the general business climate, adverse action or assessment by a regulator, unanticipated competition, the loss of key personnel, or persistent declines in an entity’s stock price below the carrying value of the entity.

In performing our goodwill impairment assessment, we compare the estimated fair value of each of our reporting units to the reporting unit's carrying value. If we conclude the fair value of a reporting unit is less than its carrying value, then we would recognize a goodwill impairment loss equal to the excess of the reporting unit's carrying amount over its estimated fair value (not to exceed the total goodwill allocated to that reporting unit). Estimation of the fair value of each reporting unit involves projections of discounted future cash flows, which are derived using certain assumptions that are subjective in nature. We also make estimates about future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, and the number of months it takes to re-lease the property, among other factors. The changing of these assumptions and the subjectivity of the market based assumptions used in the discounted future cash flow analysis, particularly the capitalization rates and discount rates, could result in a changed assessment or an incorrect assessment of the reporting unit’s estimated fair value and, therefore, could result in the misstatement of the carrying value of our reporting units and related goodwill and our reported net income/(loss) attributable to Piedmont. In addition, adverse economic conditions could also cause us to recognize additional asset impairment charges in the future, which could materially and adversely affect our business, financial condition and results of operations.

Rental Revenue Recognition

Rental income for office properties is our principal source of revenue. The timing of rental revenue recognition is largely dependent on our conclusion as to whether we, or our tenant, are the owner of tenant improvements at the leased property. The determination of whether we, or our tenant, are the owner of tenant improvements for accounting purposes is subject to significant judgment. In making that determination, we consider numerous factors and perform an evaluation of each individual lease. No one factor is determinative in reaching a conclusion. The factors we evaluate include but are not limited to the following:

•whether the tenant is obligated by the terms of the lease agreement to construct or install the leasehold improvements as a condition of the lease;

•whether the landlord can require the lessee to make specified improvements or otherwise enforce its economic rights to those assets;

•whether the tenant is required to provide the landlord with documentation supporting the cost of tenant improvements prior to reimbursement by the landlord;

•whether the landlord is obligated to fund cost overruns for the construction of leasehold improvements;

•whether the leasehold improvements are unique to the tenant or could reasonably be used by other parties; and

•whether the estimated economic life of the leasehold improvements is long enough to allow for a significant residual value that could benefit the landlord at the end of the lease term.

When we conclude that we are the owner of tenant improvements, we record the cost to construct the tenant improvements as an asset and commence rental revenue recognition when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as our asset are substantially complete, and our landlord obligation has been materially satisfied. When we conclude that our tenant is the owner of certain tenant improvements, we record our contribution towards those improvements as a lease incentive, which is amortized as a reduction to rental and tenant reimbursement revenue on a straight-line basis over the term of the related lease, and the recognition of rental revenue begins when the tenant takes possession of or controls the space.

In addition, we also record the cost of certain tenant improvements paid for or reimbursed by tenants when we conclude that we are the owner of such tenant improvements using the factors discussed above. For these tenant-funded tenant improvements, we record the amount funded or reimbursed by tenants as an asset and deferred revenue. The asset is depreciated and the deferred revenue is amortized and recognized as rental revenue over the term of the related lease beginning upon substantial completion

of the leased premises. Consequently, our determination as to whether we, or our tenant, are the owner of tenant improvements for accounting purposes has a significant impact on both the amount and timing of rental revenue that we record related to tenant-funded tenant improvements.

Related-Party Transactions and Agreements

There were no related-party transactions during the three years ended December 31, 2022, other than a consulting agreement with our former Chief Investment Officer, who retired effective June 30, 2017, and remained a consultant for us until June 30, 2020, earning $18,500 per month. During the years ended December 31, 2022, 2021, and 2020, Piedmont recognized approximately $0, $0, and $0.1 million, respectively, of expense related to this consulting agreement.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and notes thereto as of December 31, 2021 and 2020, and for the years ended December 31, 2021, 2020, and 2019, included elsewhere in this Annual Report on Form 10-K. See also “Cautionary Note Regarding Forward-Looking Statements” preceding Part I of this report and “Risk Factors" set forth in Item 1A. of this report.

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, particularly leasing of vacant space to new tenants, 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 borrowings under our $500 Million Unsecured 2018 Line of Credit as our primary sources of immediate liquidity. We have $309 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 years ended December 31, 2021 and 2020, we incurred the following types of capital expenditures (in thousands):

(1)Of the total amounts paid, approximately $6.3 million and $0.6 million related to soft costs such as capitalized interest, payroll, and other general and administrative expenses for the year ended December 31, 2021 and 2020, respectively.

"Capital expenditures for redevelopment/renovations" during the years ended December 31, 2021 and 2020 primarily 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 and 222 South Orange Avenue buildings 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" include all other capital expenditures during the respective period and are typically comprised of tenant and building improvements necessary to lease, maintain, or provide enhancements, including energy efficient equipment to our existing portfolio of office properties. We currently do not anticipate incurring any unusually large or material capital expenditures within any given year in order to meet recognized sustainable development standards, and achieve our environmental impact goals.

Given that our operating model frequently results in leases for large blocks of space to credit-worthy tenants, our leasing success can result in capital outlays which vary from one reporting period to another based upon the specific leases executed. For example, for leases executed during the year ended December 31, 2021, we committed to spend approximately $4.25 per square foot per year of lease term for tenant improvement allowances and lease commissions (net of expired lease commitments) as compared to $5.79 (net of expired lease commitments) for the year ended December 31, 2020. As of December 31, 2021, we had one individually significant unrecorded tenant allowance commitment outstanding of approximately $18.4 million related to the State of New York's lease at our 60 Broad Street building in New York.

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

33

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. Also, during the year ended December 31, 2021, we repurchased approximately 1.1 million shares at an average price of $17.76, or approximately $18.9 million. As of December 31, 2021, we had approximately $150.5 million of remaining capacity under the program which may be used for share repurchases through February 2024. Finally, other than our $500 Million Unsecured 2018 Line of Credit, which has a maturity date of September 2022 but can be extended for up to one additional year, we have no scheduled debt maturities until the second quarter of 2023. We may use capital to repay 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 (2021 vs. 2020)

Overview

As a result of a $41.0 million impairment charge related to our last remaining Chicago asset (see Note 7), that was recorded during the fourth quarter of 2021, Piedmont recognized net loss applicable to common stockholders for the year ended December 31, 2021 of $1.2 million, or $0.01 per diluted share, as compared with net income applicable to common stockholders of $232.7 million, or $1.85 per diluted share, for the year ended December 31, 2020. The year ended December 31, 2020 included approximately $196.4 million, or $1.56 per diluted share, of gains on sales of real estate assets, net of a $9.3 million loss on early extinguishment of debt, whereas the year ended December 31, 2021 included no gains or losses on sales of real estate assets or early extinguishment of debt.

Comparison of the accompanying consolidated statements of operations for the year ended December 31, 2021 vs. the year ended December 31, 2020.

The following table sets forth selected data from our consolidated statements of operations for the years ended December 31, 2021 and 2020, respectively, as well as each balance as a percentage of total revenues for the years presented (dollars in millions):

Revenue

Rental and tenant reimbursement revenue decreased approximately $5.3 million for the year ended December 31, 2021 as compared to the prior year, reflecting a full year of COVID impacts as compared to a partial year of impact in 2020. Additionally, a 1% decrease in portfolio occupancy was partially offset by accretive capital recycling activity during the two years ended December 31, 2021, rental rate increases associated with recent leasing activity across the portfolio, and higher tenant reimbursements as a result of the expiration of operating expense abatements on certain large leases during the year ended December 31, 2021.

Property management fee revenue decreased approximately $0.4 million for the year ended December 31, 2021 as compared to the prior year. Such fees fluctuate from period to period due to the variability of construction activity as well as the termination or commencement of property management agreements we may enter into with the buyers of properties in our portfolio.

Other property related income decreased approximately $0.6 million for the year ended December 31, 2021 as compared to the prior year primarily due to lower transient parking at our buildings reflecting a full year of the COVID-19 pandemic impact in 2021 versus a partial year for the year ended December 31, 2020.
