CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

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

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

•Economic, regulatory, socio-economic (including work from home), technological (e.g. Artificial Intelligence, Zoom, etc), and other changes that impact the real estate market generally, the office sector or the patterns of use of commercial office space in general, or the markets where we primarily operate or have high concentrations of revenue;

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

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

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

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

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

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

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

•Future acts of terrorism, civil unrest, or armed hostilities in any of the major metropolitan areas in which we own properties, or future cybersecurity attacks against any of our properties or our tenants;

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

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

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

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

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

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

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

1

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

•Additional risks and costs associated with inflation and continuing increases in the rate of inflation, including the impact of a possible recession;

•Uncertainties associated with environmental and regulatory matters;

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

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

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

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

•The future effectiveness of our internal controls and procedures;

•Actual or threatened public health epidemics or outbreaks, such as the COVID-19 pandemic, as well as governmental and private measures taken to combat such health crises; and

•Other factors, including the risk factors described in Item 1A. of this Annual Report on Form 10-K.

Management believes these forward-looking statements are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations. Further, forward-looking statements speak only as of the date they are made, and management undertakes no obligation to update publicly any of them in light of new information or future events.

INFORMATION REGARDING DISCLOSURES PRESENTED

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

PART I

ITEM 1.    BUSINESS

General

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

Operating Objectives and Strategy

As of December 31, 2023, we owned and operated 51 in-service office properties comprised of approximately 16.6 million square feet of primarily Class A office space which were 87.1% leased. Additionally, we have one redevelopment asset comprising 127,000 square feet in Orlando, Florida. Collectively, approximately 70% of our ALR is generated from our properties located in our Sunbelt markets. We lease space to a mixture of corporate tenants from multiple industries, and our average lease size is approximately 15,000 square feet with an average lease term remaining of approximately six years. Our diversified tenant base is primarily comprised of investment grade or nationally recognized corporations or governmental agencies, with the majority of our ALR derived from such tenants. No tenant accounts for more than 5% of our ALR and only a total of three tenants, individually, account for 3% or more of our ALR.

Headquartered in Atlanta, Georgia, with local management offices in each of our markets, Piedmont values operational excellence and is a leading participant among REITs based on the number of buildings owned and managed with Building Owners and Managers Association ("BOMA") 360 designations. BOMA 360 is a program that evaluates a building's operations and management and benchmarks its performance against industry standards. As of December 31, 2023, properties representing approximately 97% of our portfolio (based on square footage) had achieved such a designation, recognizing excellence in building operations and management. Our focus on operational excellence, fostering long-term relationships with our high-credit quality, diverse tenant base, and maintaining our portfolio of modern, amenity-rich properties, has resulted in an approximate 68% tenant retention rate over the past five years.

In addition to operational excellence, we also focus on environmental sustainability initiatives at our properties. During 2023, we were again named an Energy Star Partner of the Year for the third year in a row, as well as being selected as a 2022 Green Lease Leader by the Institute for Market Transformation and the U.S. Department of Energy's Better Buildings Alliance. Approximately 70% of our portfolio (based on square footage) has achieved and maintains Leadership in Energy and Environmental Design ("LEED") certification.

Our primary operating objectives are to maximize the risk-adjusted return to our stockholders by increasing cash flow from operations, by achieving sustainable growth in funds from operations, and by growing net asset value as a result of long-term capital appreciation. The strategies we employ to achieve these objectives include:

Redevelopment and Repositioning of Properties

We have recently redeveloped the majority of the properties within our portfolio to maintain and enhance the competitive positioning of our properties in their respective marketplaces. These redevelopment projects have focused on creating additional, or enhancing existing, amenities for our tenants to increase tenant satisfaction, occupancy, and rental rates, thereby supporting our leasing efforts and improving returns on our invested capital.

Proactive Asset and Property Management, Leasing Capabilities, and Management of Portfolio Risk

Our proactive, hospitality-minded approach to asset and property management encompasses a number of strategies designed to maximize occupancy and rental rates while following leading environmentally-conscious business practices and also meeting or exceeding the needs of today's discerning tenants. Such strategies include:

•maintaining local management offices in markets where we have a significant presence;

•offering, or being located near, superior amenities that help our tenants attract and retain their employees;

5

•maintaining our high quality properties in an environmentally-friendly manner;

•renovating our buildings to maintain their modern appearance and superior operating condition;

•building and cultivating our relationships with commercial real estate executives;

•using creative leasing approaches such as early extensions, lease wrap-arounds and restructurings; and

•utilizing a national buying platform for property management support services to ensure optimal pricing, as well as to consistently implement best practices and achieve sustainability standards.

We manage portfolio risk by:

•owning Class A office properties which are among the most desirable in their respective office sub-markets;

•focusing our portfolio primarily in high growth Sunbelt markets;

•ensuring that our tenants are credit-worthy and represent a broad spectrum of industry types with lease expirations that are laddered over many years;

•maintaining a low leverage structure, utilizing primarily unsecured financing facilities with laddered maturities;

•structuring lease expirations to avoid having multiple leases expire in the same market in a relatively short period of time;

•using our experience to meet the specialized requirements of federal, state and local government agency tenants; and

•utilizing our purchasing power and market knowledge to reduce property operating costs.

Operating our Properties in an Environmentally Responsible Manner

We strive to own and manage workplaces that are environmentally conscious, productive, and healthy for our tenants, employees, and local communities by:

•empowering our property teams with the data and tools they need to sustainably manage their buildings

•leveraging industry partnerships with BOMA, Energy Star, the U.S. Green Building Council, and GRESB, to verify and advance the environmental performance of our assets;

•implementing programs that continually improve our environmental performance and manage our climate change risk;

•setting performance targets that demonstrate our commitment to sustainable practices; and

•renovating our properties to reduce operating costs, meet recognized sustainable development standards, and reduce our environmental impact.

To combat the increasing cost of electricity, natural gas, off-site energy sources, water rates, and insurance rates at our properties and to mitigate the transitional and physical risks associated with climate change (See Item 1A. Risk Factors which follow), we have set goals to reduce property energy and water consumption and greenhouse gas emissions and improve landfill diversion rates. To reduce the risk that increasing stringent building and energy codes could increase construction, capital, and maintenance costs, we continue to update our buildings with energy efficient equipment to stay ahead of anticipated future code changes in both landlord and tenant-controlled spaces. We also closely engage with our tenants regarding our environmental initiatives and encourage them to partner with us to reduce energy use within their leased spaces. As our environmental programs have been ongoing for several years under the coordinated supervision of our National Vice President of Sustainability, we currently do not anticipate incurring any unusually large or material capital expenditures within any given year in order to meet these goals.

Further details concerning Piedmont's environmental and climate risk management strategy and programs can be found in our annual ESG report located on our website, www.piedmontreit.com under the "ESG" section. The information contained on our website is not incorporated herein by reference.

Recycling Capital Efficiently

We use our proven capital recycling capabilities to maximize total return to our stockholders by selectively disposing of non-core assets and assets for which we believe full value potential during our ownership has been achieved, and redeploying the proceeds from those dispositions into new investment opportunities with higher overall return prospects. Our investment strategy focuses on attractively priced, high quality, Class A office properties located in Sunbelt markets that we have identified based on their positive economic and demographic growth trends, strong amenity base, desired location for large corporate users, above-average job and rental rate growth, proximity to robust housing options, market-leading transportation access and infrastructure, and where we can build a significant market presence. We generally look to acquire properties that complement our existing portfolio in such a manner that efficiencies can be gained and our market expertise can be maximized. Further, from time to time we may also selectively enter into strategic joint ventures with third parties to acquire, develop, redevelop or dispose of properties, thereby potentially reducing the amount of our capital required to make investments, diversifying our sources of capital, enabling us to creatively acquire and control targeted properties, or allowing us to reduce our investment concentration in certain properties and/or markets without disrupting our operating performance or local operating capabilities.

Financing Strategy

We employ a conservative leverage strategy by targeting a debt-to-gross assets ratio of between 30% to 40%, and debt to EBITDA ratio of mid 6x or below. To effectively manage our long-term leverage strategy, we continue to analyze various sources of debt capital to prudently ladder debt maturities and to determine which sources will be the most beneficial to our investment strategy at any particular time.

Human Capital and Social Involvement

As of December 31, 2023, we had 150 employees, with approximately one-third of our employees working in our corporate office located in Atlanta, Georgia. Our remaining employees work in local management offices located in each of the office markets we serve. These employees are involved in acquiring, developing, redeveloping, leasing, and managing our portfolio of properties. We outsource various functions where cost efficiencies can be achieved, such as certain areas of information technology, construction, building engineering, and leasing. Approximately two-thirds of our workforce are salaried, with the remainder compensated on an hourly basis.

Training programs for our employees, managers, and contractors during 2023 included professional training on workplace harassment and cybersecurity. In addition, employees and managers received diversity, conflict management, collaboration, ethics, and safety training. We intend to provide an environment that is equitable, unbiased, pleasant, diverse, healthy, comfortable, and free from intimidation, hostilities, or other offenses that might interfere with work performance. We apply this policy to all of our employees, suppliers, and vendors, regardless of their geographic location.

We are committed to hiring and supporting a diverse workforce that fosters skilled and motivated people working together to deliver results in support of our core business values. We encourage all employees, tenants, and vendors to mutually respect one another's diversity in order to maintain a cohesive work environment that values fairness and equal treatment. During 2023, we continued our partnership with two Historically Black Colleges and Universities, by providing funding for the Piedmont Office Realty Trust Scholarship Program. The scholarships provide renewable, need-based, scholastic support to selected students interested in pursuing a career related to the real estate industry.

We recognize the value and benefit of employee volunteerism and fully appreciate its positive impact on the community, our employees, and ultimately, our company culture by promoting team building, collaboration, and unity. Our employees have partnered together to donate thousands of dollars and hours annually to numerous organizations.

Further details concerning our workforce and social and community involvement initiatives can be found in our annual ESG report located on our website, www.piedmontreit.com under the "ESG" section. The information contained on our website is not incorporated herein by reference.

Competition

We compete for tenants for our high-quality assets by fostering strong tenant relationships and by providing quality customer service including: leasing, asset management, property management, and construction management services. In each market where we operate, we also face significant competition for attractive investment opportunities from a large number of other real estate investors, including investors with significant capital resources such as domestic and foreign corporations and financial institutions, other publicly traded and privately held REITs, private institutional investment funds, investment banking firms, life insurance companies and pension funds. We do not face, however, the same competitors in every market. This competition,

7

along with market-specific vacancy rates and the condition of available, leasable square footage, affects the rental rates and concessions that we negotiate with our tenants. Our competitors, along with these other market factors, also influence the price we pay to acquire properties, and the proceeds we receive when we dispose of a building.

Government Regulations

All real property and the operations conducted on real property are subject to various federal, state, and local laws and regulations. Under the Americans with Disabilities Act (“ADA”) for example, places of public accommodation must meet certain federal requirements related to access and use by disabled persons. We may incur substantial costs to comply with the ADA or any other legislation. Noncompliance with ADA could result in the imposition of fines by the federal government or the award of damages to private litigants.

Furthermore, under various federal, state, and local environmental laws, ordinances, and regulations, we may be liable for the cost to remove or remediate hazardous or toxic substances, wastes, or petroleum products on, under, from, or in such property. These costs, and the costs of compliance with these laws, ordinances and regulations, could be substantial and liability under these laws may attach whether or not the owner or operator knew of, or was responsible for, the presence of such contamination. Some of these laws and regulations may impose joint and several liability on tenants, owners, or operators for the costs to investigate or remediate contaminated properties, regardless of fault or whether the acts causing the contamination were legal. The presence of hazardous substances, or the failure to properly remediate these substances, may hinder our ability to sell, rent, or pledge such property as collateral for future borrowings.

While we believe that we are currently in material compliance with these laws and regulatory requirements, compliance with new laws or regulations or stricter interpretation of existing laws by agencies or the courts may require us to incur material expenditures or may impose additional liabilities on us, including environmental liabilities. In addition, there are various local, state, and federal fire, health, life-safety, and similar regulations with which we may be required to comply, and which may subject us to liability in the form of fines or damages for noncompliance. If we were required to make significant expenditures under applicable regulations, our financial condition, results of operations, cash flows and ability to satisfy our debt service obligations and to pay distributions could be adversely affected. See Item 1A. Risk Factors for further discussion of the risks associated with compliance with regulations and environmental concerns.

Segment Information

As of December 31, 2023, our reportable segments were determined geographically based on the markets in which we have significant investments. We consider geographic location when evaluating our portfolio composition and in assessing the ongoing operations and performance of our properties. See Note 14, Segment Information, to the accompanying consolidated financial statements.

Concentration of Credit Risk

We are dependent upon the ability of our current tenants to pay their contractual rent amounts as the rents become due. The inability of a tenant to pay future rental amounts would have a negative impact on our results of operations. As of December 31, 2023, our tenants come from broadly diversified industry sectors and no individual tenant represented more than 5% of our ALR.

Other Matters

We have contracts with various governmental agencies, exclusively in the form of operating leases in buildings we own. See Item 1A. Risk Factors which follow for further discussion of the risks associated with these contracts.

ITEM 1A.    RISK FACTORS

The risks detailed below are not the only risks facing us. Please be aware that additional risks and uncertainties not currently known to us or that we currently believe to be immaterial could also materially harm our business, operating results, cash flows or financial condition, impair our future prospects, negatively affect our ability to make distributions to our stockholders or cause the price of our common stock to decline. You should also refer to the other information contained in our periodic reports, including the Cautionary Note Regarding Forward-Looking Statements, our consolidated financial statements and the related notes, and Management’s Discussion and Analysis of Financial Condition and Results of Operations for a further discussion of risks, uncertainties, and assumptions relating to our business.

Risks Related to Our Business and Operations

Economic, regulatory, socio-economic or technology changes that impact the real estate market generally, or that could affect patterns of use of commercial office space, may cause our operating results to suffer and decrease the value of our properties.

The investment returns available from equity investments in real estate depend on the amount of income earned and capital appreciation generated by the properties, as well as the expenses incurred in connection with the properties. If our properties do not generate income sufficient to meet operating expenses, including debt service and capital expenditures, then our ability to make distributions to our stockholders could be adversely affected. In addition, there are significant expenditures associated with an investment in real estate (such as debt payments, real estate taxes, insurance, and maintenance costs) that generally do not decline when circumstances reduce the income from the property. The following factors, among others, may adversely affect the operating performance and long- or short-term value of our properties:

•changes in the national, regional, or local economic climate, particularly in markets in which we have a concentration of properties;

•local office market conditions such as employment rates and changes in the supply of, or demand for, space in properties similar to those that we own within a particular area;

•changes in the patterns of office or parking garage use due to work-from-home arrangements, remote work technology (e.g. Artificial Intelligence, Zoom, etc) becoming more prevalent, or other changes that reduce the demand for office workers or parking spaces generally;

•increased demand for "co-working", open workspaces, or sharing of office space with other companies;

•increased supply of office space due to the conversion of other asset classes such as shopping malls and other retail establishments to office space;

•the attractiveness of our properties to potential tenants and competition from other available properties;

•changes in interest rates and availability of permanent financing sources that may render the sale of a property difficult or unattractive or otherwise reduce returns to stockholders;

•changes in market rental rates and related concessions granted to tenants, including free rent and tenant improvement allowances;

•the financial stability of our tenants, including bankruptcies, financial difficulties, or lease defaults by our tenants;

•the inability to finance property development or acquisitions on favorable terms;

•changes in operating costs and expenses, including costs for maintenance, insurance, and real estate taxes, and our inability to timely adjust rents in light of such changes;

•the need to periodically fund the costs to repair, renovate, and re-let space;

•earthquakes, tornadoes, hurricanes and other natural disasters, civil unrest, terrorist acts or acts of war, any of which may result in uninsured or under-insured losses;

•health crises such as the spread of communicable diseases and governmental or private measures taken to combat such health crises;

•changes in, or increased costs of compliance with, governmental regulations, including those governing usage, zoning, the environment, and taxes; and

•significant changes in accounting standards and tax laws.

In addition, periods of economic slowdown or recession, rising interest rates, or declining demand for real estate could result in a general decrease in rents or an increased occurrence of defaults under existing leases, which would adversely affect our financial condition and results of operations. Any of the above factors may prevent us from generating sufficient cash flow to operate our business, make distributions to our stockholders, or maintain the value of our properties.

We face considerable competition in the leasing market and may be unable to renew existing leases or re-let space on terms similar to the existing leases, and we may expend significant capital in our efforts to re-let space.

Every year, we compete with a number of other developers, owners, and operators of office and office-oriented, mixed-use properties to renew leases with our existing tenants and to attract new tenants. The competition for credit worthy corporate tenants is intense, and we may have difficulty competing, especially with competitors who have purchased properties at discounted prices allowing them to offer space at reduced rental rates, or those that have the ability to offer superior amenities or more flexible leasing terms. If our competitors offer office accommodations at rental rates below current market rates or below the rental rates we currently charge our tenants, we may lose potential tenants, and we may be pressured to reduce our rental rates below those we currently charge in order to retain tenants upon expiration of their existing leases. Even if our tenants renew their leases or we are able to re-let the space to new tenants, the terms and other costs of renewal or re-letting, including the cost of required renovations or additional amenities, increased tenant improvement allowances, leasing commissions, declining rental rates, and other potential concessions, may be less favorable than the terms of our current leases or require significant capital outlays. If we are unable to renew leases or re-let space in a reasonable time, or if rental rates decline or tenant improvements, leasing commissions, or other costs increase, our financial condition, operating results, or cash flows could be adversely affected.

Our rental revenues will be significantly influenced by the conditions of the office market in general and of the specific markets in which we operate.

Because our portfolio consists exclusively of office properties, we are subject to risks inherent in investments in a single property type. This concentration exposes us to the risk of economic downturns in the office sector to a greater extent than if our portfolio also included other sectors of the real estate industry. Collectively, approximately 70% of our ALR is generated from our properties located in our Sunbelt markets as of December 31, 2023. As a result, we are particularly susceptible to adverse conditions in these markets, including any reduction in demand for office properties, industry slowdowns, civil unrest, natural disasters, health crises, governmental cut backs, relocation of businesses, business layoffs or downsizing, and changing demographics. Our operations may also be affected if competing properties are built in any of these markets. Adverse economic or real estate developments in these markets, or in any of the other markets in which we operate, or any decrease in demand for office space resulting from the local or national government and business climates or changing office market trends, could adversely affect our rental revenues and operating results, and the value of our properties.

We may be adversely affected by trends in the office real estate industry.

Businesses have increasingly implemented remote work and flexible work arrangements. There has also been a trend of businesses utilizing open workspaces and “co-working” spaces. These practices enable businesses to reduce their space requirements, thereby eroding demand for commercial office space and, in turn, placing downward pressure on occupancy, rental rates and property valuations.

We depend on tenants for our revenue, and accordingly, lease terminations or tenant defaults, particularly by one of our significant lead tenants, could adversely affect the income produced by our properties.

The success of our investments materially depends on the financial stability of our tenants, any of whom may experience a change in their business at any time. If any of our tenants, or groups of tenants in specific industry sectors, experience or anticipate an adverse change in their respective businesses for any reason, they may delay lease commencements, decline to extend or renew their leases upon expiration, fail to make rental payments when due, or declare bankruptcy. Any of these actions could result in the termination of the tenants’ leases, or expiration of existing leases without renewal, and the loss of rental income attributable to the terminated or expired leases. In the event of a tenant default or bankruptcy, we may experience delays in enforcing our rights as a landlord and may incur substantial costs in protecting our investment and re-letting our property. If any leases are terminated or defaulted upon, we may also be unable to re-lease the property for the rent previously received or to sell the property without incurring a loss. In addition, significant expenditures related to debt payments, real estate taxes, insurance, and maintenance costs are generally fixed or may not decrease immediately when revenues at the related property decrease.

The occurrence of any of the situations described above, particularly if it involves one of our significant lead tenants, could seriously harm our operating performance. The revenues generated by the properties that any of our lead tenants occupy are substantially dependent upon the financial condition of these tenants and, accordingly, any event of bankruptcy, insolvency, or a general downturn in the business of any of these tenants may result in the failure or delay of such tenant’s rental payments, which may have a substantial adverse effect on our operating performance.

10

Some of our leases provide tenants with the right to terminate their leases early.

Certain of our leases permit our tenants to terminate their leases of all or a portion of the leased premises prior to their stated lease expiration dates under certain circumstances, such as providing notice by a certain date and, in many cases, paying a termination fee. In certain cases, such early terminations can be effectuated by our tenants with little or no termination fee being paid to us. To the extent that our tenants exercise early termination rights, our cash flow and earnings will be adversely affected, and we can provide no assurances that we will be able to generate an equivalent amount of net rental income by leasing the vacated space to new tenants.

We may face additional risks and costs associated with directly managing properties occupied by government tenants.

We currently own six properties in which at least one of the tenants is a federal government agency. Lease agreements with these federal government agencies contain certain provisions required by federal law, which require, among other things, that the lessor or the owner of the property complies with certain rules and regulations related to anti-kickback procedures, examination of records, audits and records, equal opportunity provisions, prohibitions against segregated facilities, certain executive orders, subcontractor costs or pricing data, and certain provisions intended to assist small businesses. Through one of our wholly-owned subsidiaries, we directly manage properties with federal government agency tenants and, therefore, we are subject to additional risks associated with compliance with all such federal rules and regulations. We face additional risks and costs associated with directly managing properties occupied by government tenants, including an increased risk of default by such tenants during periods in which state or federal governments are shut down or on furlough. There are certain additional requirements relating to the potential application of the Employment Standards Administration’s Office of Federal Contract Compliance Programs and the related requirement to prepare written affirmative action plans applicable to government contractors and subcontractors. Some of the factors used to determine whether such requirements apply to a company that is affiliated with the actual government contractor (the legal entity that is the lessor under a lease with a federal government agency) include whether such company and the government contractor are under common ownership, have common management, and are under common control. One of our wholly-owned subsidiaries is considered a government contractor, increasing the risk that requirements of these equal opportunity provisions, including the requirement to prepare affirmative action plans, may be determined to be applicable to the entire operations of our company.

Adverse market and economic conditions may cause us to recognize impairment charges on tangible real estate and related lease intangible assets or otherwise impact our performance.

We continually monitor events and changes in circumstances that could indicate that the carrying value of the real estate and related lease intangible assets 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 which indicate that the carrying value of real estate and related lease intangible assets may not be recoverable, we assess the recoverability of these assets by determining whether the carrying value will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we adjust the real estate and related lease intangible assets to their estimated fair value and recognize an impairment loss.

Projections of expected future cash flows require management to make assumptions to 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 subjectivity of assumptions used in the future cash flow analysis, including discount rates, could result in 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 lease intangible assets and our net income. 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.

Adverse market and economic conditions could cause us to recognize impairment charges on our goodwill.

We review the value of our goodwill on an annual basis and when events or changes in circumstances indicate that the carrying value of goodwill may exceed the estimated fair value of such assets. Such interim events could be adverse changes in legal matters or in the business climate, adverse action or assessment by a regulator, the loss of key personnel, or persistent declines in our stock price below our carrying value. Volatility in the overall market could cause the price of our common stock to fluctuate and cause the carrying value of our company to exceed the estimated fair value. If that occurs, our goodwill could potentially be impaired. Impairment charges recognized in order to reduce our goodwill could materially and adversely affect our results of operations. See Note 6 to our accompanying consolidated financial statements for more information.

Our earnings growth will partially depend upon future acquisitions of properties, and we may not be successful in identifying and consummating suitable acquisitions that meet our investment criteria.

Our business strategy primarily involves the acquisition of high-quality office properties in selected markets. This strategy requires us to identify suitable acquisition candidates or investment opportunities that meet our criteria and are compatible with our growth strategy. We may not be successful in identifying suitable properties or other assets that meet our acquisition criteria or in consummating acquisitions on satisfactory terms, if at all. Failure to identify or consummate acquisitions could slow our growth. Likewise, we may incur costs pursuing acquisitions that we are ultimately unsuccessful in completing.

We also face significant competition for attractive investment opportunities from a large number of other real estate investors, including investors with significant capital resources such as domestic and foreign corporations and financial institutions, other publicly traded and privately held REITs, private institutional investment funds, investment banking firms, life insurance companies and pension funds. As a result of competition, we may be unable to acquire additional properties, the purchase price may be significantly elevated, or we may have to accept lease-up risk for a property with lower occupancy, any of which could adversely affect our financial condition, results of operations or cash flows.

Future acquisitions of properties may not yield anticipated returns, may disrupt our business, and may strain management resources.

We intend to continue acquiring high-quality office properties, subject to the availability of attractive properties, our ability to arrange financing, and our ability to consummate acquisitions on satisfactory terms. In deciding whether to acquire a particular property, we make certain assumptions regarding the expected future performance of that property. However, newly acquired properties may fail to perform as expected for a variety of reasons. For example, costs necessary to bring acquired properties up to standards established for their intended market position may exceed our expectations, which may result in the properties’ failure to achieve projected returns. To the extent that we engage in acquisition activities, we will face the following risks, among others:

•we may acquire properties or other real estate-related investments that are not initially accretive to our results upon acquisition or accept lower cash flows in anticipation of longer-term appreciation, and we may not successfully manage and lease those properties to meet our expectations;

•we may not achieve expected cost savings and operating efficiencies;

•we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations;

•management attention may be diverted to the integration of acquired properties, which in some cases may turn out to be less compatible with our operating strategy than originally anticipated;

•we may not be able to support the acquired property through one of our existing property management offices and may not successfully open new satellite offices to serve additional markets;

•the acquired properties may not perform as well as we anticipate due to various factors, including changes in macro-economic conditions and the demand for office space; and

•we may acquire properties without any recourse, or with only limited recourse, for liabilities, whether known or unknown, such as clean-up of environmental contamination, unknown/undisclosed latent structural issues or maintenance problems, claims by tenants, vendors or others against the former owners of the properties, and claims for indemnification by general partners, directors, officers, and others indemnified by the former owners of the properties.

We may acquire properties in new markets, where we may face risks associated with investing in an unfamiliar market.

We have in the past and may in the future acquire properties located in markets in which we do not have an established presence. To the extent we acquire any such properties, we will face risks associated with a lack of market knowledge or understanding of the local economy, acquiring additional properties in the new market and achieving economies of scale, forging new business relationships in the area and unfamiliarity with local government and permitting procedures. As a result, the operating performance of properties acquired in new markets may be less than we anticipate, and we may have difficulty integrating such properties into our existing portfolio. In addition, the time and resources that may be required to obtain market knowledge or integrate such properties into our existing portfolio could divert our management’s attention from our existing business or other attractive opportunities.

12

The illiquidity of real estate investments could significantly impede our ability to respond to adverse changes in the performance of our properties.

Because real estate investments are relatively illiquid and large-scale office properties such as those in our portfolio are particularly illiquid, our ability to promptly sell one or more properties in our portfolio in response to changing economic, financial, investment and other conditions is limited. The real estate market is affected by many forces, such as general economic conditions, availability of financing, interest rates, and other factors, including supply and demand, that are beyond our control. We cannot predict whether we will be able to sell any property for the price or on the terms set by us or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser and to close the sale of a property. We may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot provide any assurances that we will have funds available to correct such defects or to make such improvements. Our inability to dispose of assets at opportune times or on favorable terms could adversely affect our cash flows and results of operations.

We may not be able to dispose of properties that no longer meet our strategic plans or to timely and efficiently apply the proceeds from any disposition of properties.

We may seek to dispose of properties that no longer meet our strategic plans with the intent to use the proceeds generated from such potential disposition to acquire additional properties better aligned with our investment criteria and growth strategy, to reduce debt, or to fund other operational needs. We may not be able to dispose of these properties for the proceeds we expect, or at all, and we may incur costs and divert management attention from our ongoing operations as part of efforts to dispose of these properties, regardless of whether such efforts are ultimately successful. In addition, if we are able to dispose of those properties, we may not be able to re-deploy the proceeds in a timely or more efficient manner, if at all. As such, we may not be able to adequately time any decrease in revenues from the sale of properties with a corresponding increase in revenues associated with the acquisition of new properties. The failure to dispose of properties, or to timely and efficiently apply the proceeds from any disposition of properties, could have an adverse effect on our cash flows and results of operations.

Our real estate redevelopment and development strategies may not be successful.

From time to time, we engage in various development and re-development activities to the extent attractive projects become available. When we engage in development activities, we are subject to risks associated with those activities that could adversely affect our financial condition, results of operations and cash flows, including:

•uncertainties associated with zoning, land-use, building, occupancy and other governmental permits and authorizations, as well as, environmental concerns of governmental entities or community groups;

•our builders’ ability to build in conformity with plans, specifications, budgeted costs and timetables;

•delays in completing construction could give tenants the right to terminate pre-construction leases;

•risks associated with making progress payments or other advances to builders before they complete construction;

•unanticipated additional costs related to disputes with existing tenants during redevelopment projects;

•normal lease-up risks relating to newly constructed projects;

•projects with long lead times may increase leasing risk due to changes in market conditions;

•development projects in which we have invested may be abandoned and the related investment will be impaired;

•we may not be able to obtain land on which to develop;

•we may not be able to obtain financing for development projects on favorable terms (if at all);

•construction costs of a project may exceed the original estimates or construction may not be concluded on schedule, making the project less profitable than originally estimated or not profitable at all (including the possibility of errors or omissions in the project's design, contract default, contractor or subcontractor default, performance bond surety default, the effects of local weather conditions, the possibility of local or national strikes and the possibility of shortages in materials, building supplies or energy and fuel for equipment);

•tenants which pre-lease space or contract with us for a build-to-suit project may default prior to occupying the project;

•upon completion of construction, we may not be able to obtain, or obtain on advantageous terms, permanent financing for activities that we financed through construction loans;

•we may not achieve sufficient occupancy levels and/or obtain sufficient rents to make a completed project profitable; and

•substantial renovation and development activities may require a significant amount of management’s time and attention, diverting their attention from our other operations.

Actual or threatened public health epidemics or outbreaks such as the COVID-19 pandemic, as well as governmental and private measures taken to combat such health crises, could have a material adverse effect on our business operations and financial results.

Actual or threatened public health epidemics or outbreaks, and the actions taken to combat such epidemics or outbreaks, may adversely impact the global economy or the economic and other conditions in the markets in which we operate. Among other effects, any restrictions put in place to combat public health epidemics or outbreaks could cause some of our tenants to close or operate at reduced capacity for an extended period of time, in some cases causing such tenants to default on their leases. For example, the COVID-19 pandemic and its associated variants adversely impacted the global economy and the regional U.S. economies in which we operate, and negatively impacted some of our tenants’ ability to pay their rent. The COVID-19 pandemic also accelerated some companies’ adoption of remote work platforms and could result in longer term technological and social changes that reduce the demand for office space among companies generally. Our tenants' inability to pay rent under our leases and any declines in demand for office space could adversely affect our own liquidity and operating results.

Future terrorist attacks, armed hostilities, or civil unrest in the major metropolitan areas in which we own properties could significantly impact the demand for, and value of, our properties.

Our portfolio of properties is primarily located in the following major metropolitan areas: Atlanta, Dallas, Northern Virginia/Washington, D.C., Boston, Orlando, Minneapolis, and New York, any of which could be, and some of which have been, the target of terrorist attacks, armed hostilities, or civil unrest. Future terrorist attacks and other acts of hostility, civil unrest, or war could severely impact the demand for, and value of, our properties. Terrorist attacks, other armed hostilities, or civil unrest in and around any of the major metropolitan areas in which we own properties also could directly impact the value of our properties through damage, destruction, loss, or increased security costs, and could thereafter materially impact the availability or cost of insurance to protect against such acts. Attacks, armed conflicts, or civil unrest could result in increased operating costs including building security, property and casualty insurance, and property maintenance. As a result of terrorist activities, other armed hostilities or civil unrest, the cost of insurance coverage for our properties could also increase. In addition, our insurance policies may not recover all our property replacement costs and lost revenue resulting from an attack. A decrease in demand could also make it difficult to renew or re-lease our properties at lease rates equal to or above historical rates. To the extent that any future terrorist attacks, armed hostilities, or civil unrest otherwise disrupt our tenants’ businesses, it may impair our tenants’ ability to make timely payments under their existing leases with us, which would harm our operating results.

We face risks related to the occurrence of cybersecurity incidents, or a deficiency in our information systems, which could negatively impact our business by causing a disruption to our operations, a compromise or corruption of our confidential information, and/or damage to our business relationships, all of which could negatively impact our financial results.

A cybersecurity incident is considered to be an unauthorized occurrence, or a series of related unauthorized occurrences, on or conducted through our information systems that jeopardizes the confidentiality, integrity, or availability of our information systems or any information residing therein. While we have not experienced any material cybersecurity incidents in the past, the risk of such an incident, including as a result of computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. As our reliance on technology has increased, so have the risks posed to our systems, both internal and those we have outsourced. Risks that could directly result from the occurrence of a cybersecurity incident include physical harm to occupants of our buildings, physical damage to our buildings, actual cash loss, operational interruption, regulatory investigations, fines and orders, litigation, damage to our relationship and reputation with our tenants, potential errors from misstated financial reports, violations of loan covenants, missed reporting deadlines, and private data exposure, among others. Any or all of the preceding risks could have a material adverse effect on our results of operations, financial condition and cash flows.

Insider or employee cyber and security threats, including as a result of social engineering and phishing attempts, are increasingly a concern for all companies, including ours. We are continuously working to install new networks and to upgrade our existing networks, building operating and information technology systems, and to train employees against phishing, malware and other cyber risks to ensure that we are protected, to the greatest extent possible, against cybersecurity risks and incidents. However, such upgrades, new technology and training may not be sufficient to protect us from all risks.

We are continuously developing and enhancing our controls, processes, and practices designed to protect our systems, computers, software, data, and networks from attack, damage, or unauthorized access. This continued development and enhancement will require us to expend additional resources, including to investigate and remediate any information security vulnerabilities that may be detected. Although we make efforts to maintain the security and integrity of these types of information technology networks and related systems, and despite various measures we have implemented to manage the risk of a security breach or disruption, there can be no assurance that our security efforts and measures will be effective or that

14

attempted security breaches or disruptions would not be successful or damaging. Even the most well protected information, networks, systems and facilities remain potentially vulnerable because the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases are designed to not be detected. Accordingly, we may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures, and thus it is impossible for us to entirely mitigate this risk.

Further, one or more of our tenants could experience a cyber incident which could impact their operations and ability to perform under the terms of their lease with us.

Uninsured losses or losses in excess of our insurance coverage could adversely affect our financial condition and our cash flow, and there can be no assurance as to future costs and the scope of coverage that may be available under insurance policies.

We carry comprehensive general liability, fire, rental loss, environmental, cybersecurity, and umbrella liability coverage on all of our properties and earthquake, wind, and flood coverage on properties in areas where such coverage is warranted. We believe the policy specifications and insured limits of these policies are adequate and appropriate given the relative risk of loss, the cost of the coverage, and industry practice. However, we may be subject to certain types of losses, those that are generally catastrophic in nature, such as losses due to wars, conventional or cyber terrorism, armed hostilities, chemical, biological, nuclear and radiation (“CBNR”) acts of terrorism and, in some cases, earthquakes, hurricanes, and flooding, either because such coverage is not available or is not available at commercially reasonable rates. If we experience a loss that is uninsured or that exceeds policy limits, we could lose a significant portion of the capital we have invested in the damaged property, as well as the anticipated future revenue from the property. Inflation, changes in building codes and ordinances, environmental considerations, and other factors also might make it impractical or undesirable to use insurance proceeds to replace a property after it has been damaged or destroyed. In addition, if the damaged properties are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged. Furthermore, we may not be able to obtain adequate insurance coverage at reasonable costs in the future, as the costs associated with property and casualty renewals may be higher than anticipated.

In addition, insurance risks associated with potential terrorist acts could sharply increase the premiums we pay for coverage against property and casualty claims. Under the Terrorism Risk Insurance Act, which is currently effective through December 31, 2027, United States insurers cannot exclude conventional (non-CBNR) terrorism losses and must make terrorism insurance available under their property and casualty insurance policies. However, this legislation does not regulate the pricing of such insurance. In some cases, lenders may insist that commercial property owners purchase coverage against terrorism as a condition of providing financing. Such insurance policies may not be available at a reasonable cost, which could inhibit our ability to finance or refinance our properties. In such instances, we may be required to provide other financial support, either through financial assurances or self-insurance, to cover potential losses. We may not have adequate coverage for such losses.

Should one of our insurance carriers become insolvent, we would be adversely affected.

We carry several different lines of insurance, placed with several large insurance carriers. If any one of these large insurance carriers were to become insolvent, we would be forced to replace the existing insurance coverage with another suitable carrier, and any outstanding claims would be at risk for collection. In such an event, we cannot be certain that we would be able to replace the coverage at similar or otherwise favorable terms. Replacing insurance coverage at unfavorable rates and the potential of uncollectible claims due to carrier insolvency could adversely impact our results of operations and cash flows.

Our joint venture investments could be adversely affected by a lack of sole decision-making authority and our reliance on joint venture partners’ financial condition.

From time to time we may enter into strategic joint ventures with institutional investors to acquire, develop, or improve properties, thereby reducing the amount of capital required by us to make investments and diversifying our capital sources for growth. Such joint venture investments involve risks not otherwise present in a wholly-owned property, development, or redevelopment project, including the following:

•in these investments, we may not have exclusive control over the development, financing, leasing, management, and other aspects of the project, which may prevent us from taking actions that are opposed by our joint venture partners;

•joint venture agreements often restrict the transfer of a co-venturer’s interest or may otherwise restrict our ability to sell the interest when we desire or on advantageous terms;

•we may not be in a position to exercise sole decision-making authority regarding the property or joint venture, which could create the potential risk of creating impasses on decisions, such as acquisitions or sales;

15

•such co-venturer may, at any time, have economic or business interests or goals that are, or that may become, inconsistent with our business interests or goals;

•such co-venturer may be in a position to take action contrary to our instructions, requests, policies or objectives, including our current policy with respect to maintaining our qualification as a REIT;

•the possibility that our co-venturer in an investment might become bankrupt, which would mean that we and any other remaining co-venturers would generally remain liable for the joint venture’s liabilities;

•our relationships with our co-venturers are contractual in nature and may be terminated or dissolved under the terms of the applicable joint venture agreements and, in such event, we may not continue to own or operate the interests or assets underlying such relationship or may need to purchase such interests or assets at a premium to the market price to continue ownership;

•disputes between us and our co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and board of directors from focusing their time and efforts on our business and could result in subjecting the properties owned by the applicable joint venture to additional risk; or

•we may, in certain circumstances, be liable for the actions of our co-venturers, and the activities of a joint venture could adversely affect our ability to qualify as a REIT, even though we do not control the joint venture.

Any of the above might subject a property to liabilities in excess of those contemplated and thus reduce the returns to our investors.

Costs of complying with governmental laws and regulations may reduce our net income and cash flows.

All real property and the operations conducted on real property are subject to federal, state, and local laws and regulations relating to environmental protection and human health and safety. In addition, under the Americans with Disabilities Act ("ADA"), places of public accommodation must meet certain federal requirements related to access and use by disabled persons. Tenants’ ability to operate and to generate income to pay their lease obligations may be affected by permitting and compliance obligations arising under such laws and regulations. Some of these laws and regulations may impose joint and several liability on tenants, owners, or operators for the costs to investigate or remediate contaminated properties, regardless of fault or whether the acts causing the contamination were legal. Noncompliance with ADA could result in the imposition of fines by the federal government or the award of damages to private litigants. In addition, the presence of hazardous substances, or the failure to properly remediate these substances, may hinder our ability to sell, rent, or pledge such property as collateral for future borrowings.

Compliance with new laws or regulations or stricter interpretation of existing laws by agencies or the courts may require us to incur material expenditures or may impose additional liabilities on us, including environmental liabilities. In addition, there are various local, state, and federal fire, health, life-safety, and similar regulations with which we may be required to comply, and which may subject us to liability in the form of fines or damages for noncompliance. Although we believe that our properties are currently in material compliance with these regulatory requirements, we have not conducted an audit or investigation of all of our properties to determine our compliance, and we cannot predict the ultimate cost of compliance. Any material expenditures, liabilities, fines, or damages we must pay will reduce our net income and cash flows.

As the present or former owner or operator of real property, we could become subject to liability for environmental contamination, regardless of whether we caused such contamination.

Under various federal, state, and local environmental laws, ordinances, and regulations, a current or former owner or operator of real property may be liable for the cost to remove or remediate hazardous or toxic substances, wastes, or petroleum products on, under, from, or in such property. These costs could be substantial and liability under these laws may attach whether or not the owner or operator knew of, or was responsible for, the presence of such contamination. As a result, our tenants’ operations, the existing condition of land when we buy it, operations in the vicinity of our properties such as the presence of underground storage tanks or activities of unrelated third parties may affect our properties. Even if more than one party may have been responsible for the contamination, each liable party may be held entirely responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a property for damages based on personal injury, natural resources, or property damage and/or for other costs, including investigation and clean-up costs, resulting from the environmental contamination. The presence of contamination on one of our properties, or the failure to properly remediate a contaminated property, could give rise to a lien in favor of the government for costs it may incur to address the contamination, or otherwise adversely affect our ability to sell or lease the property or borrow using the property as collateral. In addition, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which property may be used or businesses may be operated, and these restrictions may require substantial expenditures or prevent us from entering into leases with prospective tenants.

16

Some of our properties are adjacent to or near other properties that have contained or currently contain underground storage tanks used to store petroleum products or other hazardous or toxic substances. In addition, certain of our properties are on, adjacent to, or near sites upon which others, including former owners or tenants of our properties, have engaged, or may in the future engage, in activities that have released or may have released petroleum products or other hazardous or toxic substances.

The cost of defending against claims of liability, of remediating any contaminated property, or of paying personal injury claims could reduce our net income and cash flows.

We could become subject to liability for adverse environmental conditions in the buildings on our property.

Some of our properties have building materials that contain asbestos. Environmental laws require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, adequately inform or train those who may come into contact with asbestos, and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements. In addition, environmental laws and the common law may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos.

Our properties also may contain or develop harmful mold or suffer from other air quality issues. Any of these materials or conditions could result in liability for personal injury and costs of remediating adverse conditions, which could have an adverse effect on our results of operations or cash flows.

As the owner of real property, we could become subject to liability for a tenant’s failure to comply with environmental requirements regarding the handling and disposal of regulated substances and wastes or for non-compliance with health and safety requirements, which requirements are subject to change.

Some of our tenants may handle regulated substances and wastes as part of their operations at our properties. Environmental laws regulate the handling, use, and disposal of these materials and subject our tenants, and potentially us, to liability resulting from non-compliance with these requirements. The properties in our portfolio also are subject to various federal, state, and local health and safety requirements, such as state and local fire requirements. If we or our tenants fail to comply with these various requirements, we might incur governmental fines or private damage awards. Moreover, we do not know whether or the extent to which existing requirements or their enforcement will change or whether future requirements will require us to make significant unanticipated expenditures, either of which could materially and adversely impact our financial condition, results of operations or cash flows. If our tenants become subject to liability for noncompliance, it could affect their ability to make rental payments to us.

We face risks associated with the physical effects of climate change.

The physical effects of climate change could have a material adverse effect on our properties, operations, and business. The majority of our portfolio of properties is located along the Eastern coast of the United States. Our markets could experience increases in rainfall, storm intensity, larger flood zones, water shortages, hurricanes, changing temperature averages or extremes, or rising sea-levels as a result of global climate change. Over time, these conditions could result in physical damage to our buildings or a decline in demand for office space in our buildings. Climate change could also indirectly negatively impact our business by causing increased costs associated with energy, storm cleanup, or property and casualty or flood insurance premiums, deductibles, claims or liabilities, or a decrease in or unavailability of coverage, for properties in areas subject to severe weather.

We may face risks associated with the transition to a lower-carbon economy.

Transitioning to a lower-carbon economy may entail extensive policy, legal, technological, and market changes to address mitigation and adaption requirements related to climate change. Depending on the nature, speed, and focus of these changes, transition risks may pose varying levels of financial and reputational risk to us or our tenants. Policy action around climate change such as implementing carbon-pricing mechanisms to reduce green house gas emission, shifting energy use toward lower emission sources, adopting energy-efficiency solutions, encouraging greater water efficiency measures, and promoting more sustainable land-use practices can result in financial impacts to both us and our tenants, including additional costs of auditing and reporting such data. Alterations to third-party certifications/ratings may impact investor or tenant demand and consequential valuation for buildings with lower scoring. Climate related litigation claims can result in financial and reputational damage. Technology improvements or innovations that support the transition to a lower-carbon, energy efficient economic system and shifts in supply and demand for certain commodities, products, and services as climate-related risks and opportunities are increasingly taken into account may affect the strength and competitiveness of our tenants' business, and ultimately their ability to meet their rental obligations to us. Climate change has also been identified as a potential source of

17

reputational risk tied to changing customer or community perceptions of an organization's contribution to or detraction from the transition to a lower-carbon economy.

We depend on key personnel, each of whom would be difficult to replace.

Our continued success depends to a significant degree upon the continued contributions of certain key personnel, each of whom would be difficult to replace. Our ability to retain our management team, or to attract suitable replacements should any member of the management team leave, is dependent on the competitive nature of the employment market. The loss of services of one or more key members of our management team could adversely affect our results of operations and slow our future growth. While we have planned for the succession of each of the key members of our management team, our succession plans may not effectively prevent any adverse effects from the loss of any member of our management team. We have not obtained and do not expect to obtain “key person” life insurance on any of our key personnel.

We may be subject to litigation, which could have a material adverse effect on our financial condition.

From time to time, we may be subject to legal action arising in the ordinary course of our business or otherwise. Such action could distract key personnel from management of the company and result in additional expenses which, if uninsured, could adversely impact our earnings and cash flows, thereby impacting our ability to service our debt and make distributions to our stockholders. There can be no assurance that our insurance policies will fully cover any payments or legal costs associated with any potential legal action. Further, the ultimate resolution of such action could impact the availability or cost of some of our insurance coverage, which could adversely impact our results of operations and cash flows, expose us to increased risks that would be uninsured, or adversely impact our ability to attract officers and candidates for our board of directors.

If our disclosure controls or internal controls over financial reporting are not effective, investors could lose confidence in our reported financial information.

The design and effectiveness of our disclosure controls and procedures and our internal control over financial reporting may not prevent all errors, misstatements, or misrepresentations. Although management will continue to review the effectiveness of our disclosure controls and procedures and our internal control over financial reporting, there can be no guarantee that these processes will be effective in accomplishing all control objectives all of the time. Deficiencies, including any material weakness, in our internal control over financial reporting which may occur in the future could result in misstatements of our results of operations, restatements of our financial statements, a decline in the trading price of our common stock, or otherwise materially adversely affect our business, reputation, results of operations, financial condition, or liquidity.

Risks Related to Our Organization and Structure

Our organizational documents contain provisions that may have an anti-takeover effect, which may discourage third parties from conducting a tender offer or seeking other change of control transactions that could involve a premium price for our common stock or otherwise benefit our stockholders.

Our charter and bylaws contain provisions that may have the effect of delaying, deferring, or preventing a change in control of our company (including an extraordinary transaction such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for our common stock or otherwise be in the best interest of our stockholders. These provisions include, among other things, restrictions on the ownership and transfer of our stock, advance notice requirements for stockholder nominations for our board of directors and other business proposals, and our board of directors’ power to classify or reclassify unissued shares of common or preferred stock and issue additional shares of common or preferred stock.

In order to preserve our REIT status, our charter limits the number of shares a person may own, which may discourage a takeover that could result in a premium price for our common stock or otherwise benefit our stockholders.

Our charter, with certain exceptions, authorizes our board of directors to take such actions as are necessary and desirable to preserve our qualification as a REIT for federal income tax purposes. Unless exempted by our board of directors, no person may actually or constructively own more than 9.8% (by value or number of shares, whichever is more restrictive) of the outstanding shares of our common stock or the outstanding shares of any class or series of our preferred stock, which may inhibit large investors from desiring to purchase our stock. This restriction may have the effect of delaying, deferring, or preventing a change in control, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for our common stock or otherwise be in the best interest of our stockholders.

18

Our board of directors can take many actions without stockholder approval.

Our board of directors has overall authority to oversee our operations and determine our major corporate policies. This authority includes significant flexibility. For example, our board of directors can do the following:

•within the limits provided in our charter, prevent the ownership, transfer, or accumulation of stock in order to protect our status as a REIT or for any other reason deemed to be in our best interest and the interest of our stockholders;

•issue additional shares of stock without obtaining stockholder approval, which could dilute the ownership of our then-current stockholders;

•amend our charter to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue, without obtaining stockholder approval;

•classify or reclassify any unissued shares of our common or preferred stock and set the preferences, rights and other terms of such classified or reclassified shares, without obtaining stockholder approval;

•employ and compensate affiliates;

•direct our resources toward investments, which ultimately may not appreciate over time;

•change creditworthiness standards with respect to our tenants;

•change our investment or borrowing policies; and

•determine that it is no longer in our best interest to attempt to qualify, or to continue to qualify, as a REIT.

Any of these actions could increase our operating expenses, impact our ability to make distributions, or reduce the value of our assets without giving our stockholders the right to vote.

Our charter permits our board of directors to issue stock with terms that may subordinate the rights of our common stockholders, which may discourage a third party from acquiring us in a manner that could result in a premium price for our common stock or otherwise benefit our stockholders.

Our board of directors may, without stockholder approval, issue authorized but unissued shares of our common or preferred stock and amend our charter to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue. In addition, our board of directors may, without stockholder approval, classify or reclassify any unissued shares of our common or preferred stock and set the preferences, rights and other terms of such classified or reclassified shares. Thus, our board of directors could authorize the issuance of preferred stock with terms and conditions that could have priority with respect to distributions and amounts payable upon liquidation over the rights of the holders of our common stock. Such preferred stock also could have the effect of delaying, deferring, or preventing a change in control, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for our common stock, or otherwise be in the best interest of our stockholders.

Our board of directors could elect for us to be subject to certain Maryland law limitations on changes in control that could have the effect of preventing transactions in the best interest of our stockholders.

Certain provisions of Maryland law may have the effect of inhibiting a third party from making a proposal to acquire us, or these certain provisions may also impede a change of control under certain circumstances that otherwise could provide the holders of shares of our common stock with the opportunity to realize a premium over the then-prevailing market price of such shares, including:

•“business combination” provisions that, subject to limitations, prohibit certain business combinations between us and an “interested stockholder” (defined generally as any person who beneficially owns 10% or more of the voting power of our outstanding voting stock or any affiliate or associate of ours who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of our then outstanding stock) or an affiliate thereof for five years after the most recent date on which the stockholder becomes an interested stockholder and thereafter impose supermajority voting requirements on these combinations; and

•“control share” provisions that provide that “control shares” of our company (defined as shares which, when aggregated with other shares controlled by the stockholder, except solely by virtue of a revocable proxy, entitle the stockholder to exercise one of three increasing ranges of voting power in electing candidates for the board of directors) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of “control shares”) have no voting rights except to the extent approved by our stockholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

Our bylaws contain a provision exempting any acquisition by any person of shares of our stock from the control share acquisition statute, and our board of directors has adopted a resolution exempting any business combination with any person from the business combination statute. As a result, these provisions currently will not apply to a business combination or

19

control share acquisition involving our company. However, our board of directors still has the ability to opt into the business combination provisions and the control share provisions of Maryland law in the future.

Our charter, our bylaws, the limited partnership agreement of our operating partnership, and Maryland law also contain other provisions that may delay, defer, or prevent a transaction or a change of control that might involve a premium price for our common stock or otherwise be in the best interest of our stockholders. In addition, the employment agreements with certain of our executive officers contain, and grants under our incentive plan also may contain, change-in-control provisions that might similarly have an anti-takeover effect, inhibit a change of our management, or inhibit in certain circumstances tender offers for our common stock or proxy contests to change our board.

Our rights and the rights of our stockholders to recover claims against our board of directors and officers are limited, which could reduce our recovery and our stockholders’ recovery against them if they negligently cause us to incur losses.

Maryland law provides that a director or officer has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in our best interest and with the care that an ordinarily prudent person in a like position would use under similar circumstances. Our charter eliminates our board of directors’ and officers’ liability to us and our stockholders for money damages except for liability resulting from actual receipt of an improper benefit or profit in money, property, or services or active and deliberate dishonesty established by a final judgment and which is material to the cause of action. Our charter and bylaws require us to indemnify our board of directors and officers to the maximum extent permitted by Maryland law for any claim or liability to which they may become subject or which they may incur by reason of their service as members of the board of directors or officers, except to the extent that the act or omission of the director or officer was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty, the director or officer actually received an improper personal benefit in money, property, or services, or, in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. As a result, we and our stockholders may have more limited rights against our board of directors and officers than might otherwise exist under common law, which could reduce our and our stockholders’ recovery from these persons if they act in a negligent manner. In addition, we may be obligated to fund the defense costs incurred by our board of directors and officers (as well as by our employees and agents) in some cases.

Risks Related to Tax Matters

Our failure to qualify as a REIT could adversely affect our operations and our ability to make distributions.

We are owned and operated in a manner intended to qualify us as a REIT for U.S. federal income tax purposes; however, we do not have a ruling from the IRS as to our REIT status. In addition, we own all of the common stock of a subsidiary that has elected to be treated as a REIT, and if our subsidiary REIT were to fail to qualify as a REIT, it is possible that we also would fail to qualify as a REIT unless we (or the subsidiary REIT) could qualify for certain relief provisions. Our qualification and the qualification of our subsidiary REIT as a REIT will depend on satisfaction, on an annual or quarterly basis, of numerous requirements set forth in highly technical and complex provisions of the Code for which there are only limited judicial or administrative interpretations. A determination as to whether such requirements are satisfied involves various factual matters and circumstances not entirely within our control. The fact that we hold substantially all of our assets through our operating partnership and its subsidiaries further complicates the application of the REIT requirements for us. No assurance can be given that we, or our subsidiary REIT, will qualify as a REIT for any particular year.

If we, or our subsidiary REIT, were to fail to qualify as a REIT in any taxable year for which a REIT election has been made, the non-qualifying REIT would not be allowed a deduction for dividends paid to its stockholders in computing its taxable income and would be subject to U.S. federal income tax on its taxable income at corporate rates. Moreover, unless the non-qualifying REIT were to obtain relief under certain statutory provisions, the non-qualifying REIT also would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification is lost. This treatment would reduce our net earnings available for investment or distribution to our stockholders because of the additional tax liability to us for the years involved. As a result of such additional tax liability, we might need to borrow funds or liquidate certain investments on terms that may be disadvantageous to us in order to pay the applicable tax.

20

Failure of our operating partnership to be treated as a disregarded entity or a partnership would have serious adverse consequences to our stockholders.

If the IRS were to successfully challenge the tax status of the operating partnership or any of its subsidiary partnerships or real estate ventures for federal income tax purposes, the operating partnership or the affected partnership or real estate venture would be taxable as a corporation. In such event, we would cease to qualify as a REIT and the imposition of a corporate tax on the operating partnership, subsidiary partnership, or real estate venture would reduce the amount of cash available for distribution from the operating partnership to us and ultimately to our stockholders.

Changes in tax laws may eliminate the benefits of REIT status, prevent us from maintaining our qualification as a REIT, or otherwise adversely affect our stockholders.

New legislation, regulations, administrative interpretations or court decisions could change the tax laws or interpretations of the tax laws regarding qualification as a REIT, or the federal income tax consequences of that qualification, in a manner that is materially adverse to our stockholders. In particular, the Tax Cuts and Jobs Act ("H.R. 1"), which was effective for us for tax year 2018, made many significant changes to the U.S. federal income tax laws. A number of the changes that affected noncorporate taxpayers will expire at the end of 2025 unless Congress acts to extend them. These changes impacted us, our stockholders, and our tenants in various ways and the IRS continues to issue clarifying guidance with respect to certain of the provisions of H.R. 1, any of which may be adverse or potentially adverse compared to prior law. Additional changes to tax laws are likely to continue to occur in the future. Accordingly, there is no assurance that we can continue to operate with the current benefits of our REIT status or that a change to the tax laws will not adversely affect the taxation of our stockholders. If there is a change in the tax laws that prevents us from qualifying as a REIT, that eliminates REIT status generally, or that requires REITs generally to pay corporate level income taxes, our results of operations may be adversely affected and we may not be able to make the same level of distributions to our stockholders, and changes to the taxation of our stockholders could have an adverse effect on an investment in our common stock. Investors are urged to consult with their own tax advisor with respect to the impact of recent legislation on ownership of shares and the status of legislative, regulatory, or administrative developments and proposals, and their potential effect on ownership of shares.

Even if we qualify as a REIT, we may incur certain tax liabilities that would reduce our cash flow and impair our ability to make distributions.

Even if we maintain our status as a REIT, we may be subject to U.S. federal income taxes or state taxes, which would reduce our cash available for distribution to our stockholders. For example, we will be subject to federal income tax on any undistributed REIT taxable income. Further, if we fail to distribute during each calendar year at least the sum of (a) 85% of our ordinary income for such year, (b) 95% of our net capital gain income for such year, and (c) any undistributed taxable income from prior periods, we will be subject to a 4% excise tax on the excess of the required distribution over the sum of (i) the amounts actually distributed by us, plus (ii) retained amounts on which we pay income tax at the corporate level. If we realize net income from foreclosure properties that we hold primarily for sale to customers in the ordinary course of business, we must pay tax thereon at the highest corporate income tax rate, and if we sell a property, other than foreclosure property, that we are determined to have held for sale to customers in the ordinary course of business, any gain realized would be subject to a 100% “prohibited transaction” tax. The term “prohibited transaction” generally includes a sale or other disposition of property (other than foreclosing property) that is held primarily for sale to customers in the ordinary course of a trade or business. The determination as to whether or not a particular sale is a prohibited transaction depends on the facts and circumstances related to that sale. We cannot guarantee that sales of our properties would not be prohibited transactions unless we comply with certain safe-harbor provisions. The need to avoid prohibited transactions could cause us to forgo or defer sales of properties that might otherwise be in our best interest to sell. In addition, we own interests in certain taxable REIT subsidiaries that are subject to federal income taxation and we and our subsidiaries may be subject to state and local taxes on our income or property.

Differences between the recognition of taxable income and the actual receipt of cash could require us to sell assets or borrow funds on a short-term or long-term basis to meet the distribution requirements of the Code.

We intend to make distributions to our stockholders to comply with the requirements of the Code for REITs and to minimize or eliminate our corporate tax obligations; however, differences between the recognition of taxable income and the actual receipt of cash could require us to sell assets or borrow funds on a short-term or long-term basis to meet the distribution requirements of the Code. Certain types of assets generate substantial disparity between taxable income and available cash, such as real estate that has been financed through financing structures which require some or all of available cash flows to be used to service borrowings. In addition, changes made by H.R. 1 will require us to accrue certain income for U.S. federal income tax purposes no later than when such income is taken into account as revenue on our financial statement (subject to an exception for certain income that is already subject to a special method of accounting under the Code). This could cause us to recognize taxable

21

income prior to the receipt of the associated cash. H.R. 1 also includes limitations on the deductibility of certain compensation paid to our executives, certain interest payments, and certain net operating loss carryforwards, each of which could potentially increase our taxable income and our required distributions. Under H.R. 1, federal net operating losses incurred in taxable years beginning after December 31, 2017 can be carried forward indefinitely. Net operating losses of a REIT may not be carried back to any taxable year, regardless of whether the taxpayer qualified as a REIT in such taxable year. In addition, for taxable years beginning after December 31, 2017, H.R. 1 limits the deduction of net operating losses to 80% of current year taxable income (determined without regard to the deduction for dividends paid). Additionally, Section 163(j) of the Code, as amended by H.R. 1, limits the deductibility of net interest expense paid or accrued on debt properly allocable to a trade or business to 30% of “adjusted taxable income,” subject to certain exceptions, plus the taxpayer’s business interest income for the tax year. As a result, the requirement to distribute a substantial portion of our taxable income could cause us to: (1) sell assets in adverse market conditions, (2) borrow on unfavorable terms, or (3) distribute amounts that would otherwise be invested in future acquisitions, capital expenditures, or repayment of debt, in order to comply with REIT requirements. Any such actions could increase our costs and reduce the value of our common stock. Further, we may be required to make distributions to our stockholders when it would be more advantageous to reinvest cash in our business or when we do not have funds readily available for distribution. Compliance with REIT qualification requirements may, therefore, hinder our ability to operate solely on the basis of maximizing profits.

Distributions made by REITs do not qualify for the reduced tax rates that apply to certain other corporate distributions.

The maximum federal income tax rate for certain dividends paid by domestic corporations to individuals, trusts and estates is generally 20%. Dividends paid by REITs, however, (other than distributions we properly designate as capital gain dividends or as qualified dividend income) are taxed at the normal income tax rate applicable to the individual recipient (currently a maximum rate of 37%) rather than the 20% preferential rate, subject to a deduction equal to 20% of the amount of certain “qualified REIT dividends” (generally, dividends received by a REIT stockholder that are not designated as capital gain dividends or qualified dividend income) that is available to noncorporate taxpayers through 2025, which has the effect of reducing the maximum effective income tax rate on qualified REIT dividends to 29.6%. The more favorable rates applicable to regular corporate dividends could cause investors who are individuals to perceive investments in REITs to be relatively less attractive than investments in non-REIT corporations that make distributions, particularly after the scheduled expiration of the 20% deduction applicable to qualified REIT dividends on December 31, 2025.

A recharacterization of transactions undertaken by our operating partnership may result in lost tax benefits or prohibited transactions, which would diminish cash distributions to our stockholders, or even cause us to lose REIT status.

The IRS could recharacterize transactions consummated by our operating partnership, which could result in the income realized on certain transactions being treated as gain realized from the sale of property that is held as inventory or otherwise held primarily for the sale to customers in the ordinary course of business. In such event, the gain would constitute income from a prohibited transaction and would be subject to a 100% tax. If this were to occur, our ability to make cash distributions to our stockholders would be adversely affected. Moreover, our operating partnership may purchase properties and lease them back to the sellers of such properties. While we will use our best efforts to structure any such sale-leaseback transaction such that the lease will be characterized as a “true lease,” thereby allowing us to be treated as the owner of the property for federal income tax purposes, we can give stockholders no assurance that the IRS will not attempt to challenge such characterization. In the event that any such sale-leaseback transaction is challenged and recharacterized as a financing transaction or loan for U.S. federal income tax purposes, deductions for depreciation and cost recovery relating to such property would be disallowed. If a sale-leaseback transaction were so recharacterized, the amount of our adjusted REIT taxable income could be recalculated, which might cause us to fail to meet the distribution requirement for a taxable year. We also might fail to satisfy the REIT qualification asset tests or income tests and, consequently, lose our REIT status. Even if we maintain our status as a REIT, an increase in our adjusted REIT taxable income could cause us to be subject to additional federal and state income and excise taxes. Any federal or state taxes we pay will reduce our cash available for distribution to our stockholders.

We face possible adverse changes in state and local tax laws regarding the treatment of REITs and their stockholders, which may result in an increase in our tax liability.

From time to time, changes in state and local tax laws or regulations are enacted, including changes to a state’s treatment of REITs and their stockholders, which may result in an increase in our tax liability. Any shortfall in tax revenues for states and municipalities may lead to an increase in the frequency and size of such changes. If such changes occur, we may be required to pay additional taxes on our assets or income. These increased tax costs could adversely affect our financial condition and results of operations and the amount of cash available for distributions to our stockholders.

22

Property taxes may decrease returns on real estate.

Real property owned by us will be subject to real property taxes and, in some instances, personal property taxes or franchise taxes. Such real and personal property taxes and franchise taxes may increase as property tax or franchise tax rates change and as the properties are assessed or reassessed by taxing authorities. An increase in property taxes on or franchise taxes related to our real property could affect adversely our financial condition, results of operations, cash flow and ability to make distributions to stockholders and could decrease the value of that real property.

Risks Associated with Debt Financing

We have incurred and are likely to continue to incur mortgage and other indebtedness, which may increase our business risks.

As of December 31, 2023, we had total outstanding indebtedness of approximately $2.1 billion, including $197.0 million of mortgage debt. Although the instruments governing our indebtedness limit our ability to incur additional indebtedness, these restrictions are subject to a number of qualifications and exceptions and, under certain circumstances, debt incurred in compliance with these restrictions could be substantial. We may incur additional indebtedness to acquire properties or other real estate-related investments, to fund property improvements, and other capital expenditures or for other corporate purposes.

Significant borrowings by us increase the risks of investors' willingness to make an investment in us. Our ability to make payments on our indebtedness and to fund our operations, working capital and capital expenditures, depends on our ability to generate cash in the future. Our cash flow is subject to general economic, industry, financial, competitive, operating, legislative, regulatory and other factors, many of which are beyond our control. Our failure to pay amounts due with respect to any of our indebtedness may constitute an event of default under the instrument governing that indebtedness, which could permit the holders of that indebtedness to require the immediate repayment of that indebtedness in full. Moreover, any acceleration of, or default, with respect to any of our indebtedness could, in turn, constitute an event of default under other debt instruments or agreements, thereby resulting in the acceleration and required repayment of that other indebtedness.

Periodically, we may need to refinance all or a portion of our indebtedness on or before maturity. Our ability to refinance our indebtedness or obtain additional financing will depend on, among other things our financial condition, results of operations and market conditions at the time; and restrictions in the agreements governing our indebtedness. As a result, we may not be able to refinance our indebtedness on commercially reasonable terms, or at all. If we do not generate sufficient cash flow from operations, and additional borrowings or refinancings or proceeds of assets sales or other sources of cash are not available to us, we may not have sufficient cash to enable us to meet all of our obligations. Accordingly, if we cannot service our indebtedness, we may have to take actions such as seeking additional equity financing, delaying capital expenditures or strategic acquisitions and alliances. Any of these events or circumstances could have a material adverse effect on our financial condition, results of operations, cash flows, the trading price of our securities and our ability to satisfy our debt service obligations.

Rising interest rates may make it difficult for us to finance or refinance properties, which could reduce the number of properties we can acquire, our net income, and the amount of cash distributions we can make.

If debt financing is unavailable at reasonable rates, we may not be able to finance the purchase of properties. If we place mortgage debt on properties, we run the risk of being unable to refinance the properties when the loans become due, or of being unable to refinance on favorable terms. If interest rates are higher when we refinance our properties, our income could be reduced. If any of these events occur, our cash flow could be reduced. This, in turn, could reduce cash available for distribution to our stockholders and may hinder our ability to raise more capital by issuing more stock or by borrowing more money.

Agreements governing our existing indebtedness contain, and future financing arrangements will likely contain, restrictive covenants relating to our operations, which could limit our ability to make distributions to our stockholders.

We are subject to certain restrictions pursuant to the restrictive covenants of our outstanding indebtedness, which may affect our distribution and operating policies and our ability to incur additional debt. Loan documents evidencing our existing indebtedness contain, and loan documents entered into in the future will likely contain, certain operating covenants that limit our ability to mortgage a property or discontinue insurance coverage. In addition, the agreements governing our existing indebtedness contain financial covenants, including certain coverage ratios and limitations on our ability to incur secured and unsecured debt, make dividend payments, sell all or substantially all of our assets, and engage in mergers and consolidations and certain acquisitions. Covenants under our existing indebtedness do, and under any future indebtedness likely will, restrict our ability to pursue certain business initiatives or certain acquisition transactions. In addition, failure to meet any of these covenants, including the financial coverage ratios, could cause an event of default under or accelerate some or all of our indebtedness, which would have a material adverse effect on us.

23

Increases in interest rates would cause the amount of our variable-rate debt payments to also increase and could limit our ability to make distributions to our stockholders.

Currently, any outstanding draws on our $600 Million Unsecured 2022 Line of Credit and our variable-rate debt instruments which are not subject to hedging under interest rate swap agreements represent our exposure to interest rate changes. In addition, any outstanding draws under the $600 Million Unsecured 2022 Line of Credit are subject to Adjusted SOFR locks of various length. However, increases in interest rates could increase our interest costs associated with this variable rate debt to the extent our current locks expire and new balances are drawn under the facility. Such increases would reduce our cash flows and could impact our ability to make distributions to our stockholders. In addition, if we are required to repay existing debt during periods of higher interest rates, we may need to sell one or more of our investments in order to repay the debt, which might not permit realization of the maximum return on such investments.

Changes in interest rates could have adverse effects on our cash flows as a result of our interest rate derivative contracts.

We have entered into various interest rate derivative agreements to effectively fix our exposure to interest rates under certain of our existing debt facilities. To the extent interest rates are higher than the fixed rate in the respective contract, we would realize cash savings as compared to other market participants. However, to the extent interest rates are below the fixed rate in the respective contract, we would make higher cash payments than other similar market participants, which would have an adverse effect on our cash flows as compared to other market participants.

Additionally, there is counterparty risk associated with entering into interest rate derivative contracts. Should market conditions lead to insolvency or make a merger necessary for one or more of our counterparties, or potential future counterparties, it is possible that the terms of our interest rate derivative contracts will not be honored in their current form with a replacement counterparty. The potential termination or renegotiation of the terms of the interest rate derivative contracts as a result of changing counterparties through insolvency or merger could result in an adverse impact on our results of operations and cash flows.

A downgrade in our credit ratings, the credit ratings of the Operating Partnership or the credit ratings of our or the Operating Partnership's unsecured debt securities could materially adversely affect our business and financial condition.

The credit ratings assigned to us, to the Operating Partnership and to our and their unsecured debt securities could change based upon, among other things, our results of operations and financial condition. If any of the credit rating agencies that have rated us, the Operating Partnership or our or their unsecured debt securities downgrades or lowers these credit ratings, or if any credit rating agency indicates that it has placed any such rating on a so-called “watch list” for possible downgrading or lowering or otherwise indicates that its outlook for that rating is negative, it could have a material adverse effect on our costs (including by increasing interest expense as a result of increases in the state interest rate spreads over reference rates or increased interest rate step-ups on certain of our or the Operating Partnership's debt instruments) and availability of capital, which could in turn have a material adverse effect on our financial condition, results of operations, cash flows and our ability to satisfy our debt service obligations.

General Risks

Any change in our dividend policy could have a material adverse effect on the market price of our common stock.

Distributions are authorized and determined by our board of directors in its sole discretion and depend upon a number of factors, including:

•cash available for distribution;

•our results of operations and anticipated future results of operations;

•our financial condition, especially in relation to our anticipated future capital needs of our properties;

•the level of reserves we establish for future capital expenditures;

•the distribution requirements for REITs under the Code;

•the level of distributions paid by comparable listed REITs;

•our operating expenses; and

•other factors our board of directors deems relevant.

24

We expect to continue to pay quarterly distributions to our stockholders; however, we bear all expenses incurred by our operations, and our funds generated by operations, after deducting these expenses, may not be sufficient to cover desired levels of distributions to our stockholders. Any change in our dividend policy could have a material adverse effect on the market price of our common stock.

There are significant price and volume fluctuations in the public markets, including on the exchange which we listed our common stock.

The U.S. stock markets, including the NYSE on which our common stock is listed, have historically experienced significant price and volume fluctuations. The market price of our common stock may be highly volatile and could be subject to wide fluctuations and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. If the market price of our common stock declines significantly, stockholders may be unable to resell their shares at or above their purchase price. We cannot assure stockholders that the market price of our common stock will not fluctuate or decline significantly in the future. Some of the factors that could negatively affect our stock price or result in fluctuations in the price or trading volume of our common stock include, but are not limited to, the following:

•changes in the perceived demand for office space;

•actual or anticipated variations in our quarterly operating results;

•changes in our earnings estimates or publication of research reports about us or the real estate industry, although no assurance can be given that any research reports about us will be published or the accuracy of such reports;

•changes in our dividend policy;

•future sales of substantial amounts of our common stock by our existing or future stockholders;

•increases in market interest rates, which may lead purchasers of our stock to demand a higher yield;

•changes in market valuations of similar companies;

•adverse market reaction to any increased indebtedness we incur in the future;

•change in the credit ratings assigned to us, the Operating Partnership or our or their unsecured debt securities;

•additions or departures of key personnel;

•actions by institutional stockholders;

•material, adverse litigation judgments;

•speculation in the press or investment community;

•general market and economic conditions; and

•the realization of any of the other risk factors described in this report.

Future offerings of debt securities, which would be senior to our common stock upon liquidation, or equity securities, which would dilute our existing stockholders and may be senior to our common stock for the purposes of distributions, may adversely affect the market price of our common stock.

We may attempt to increase our capital resources by making additional offerings of debt or equity securities, including medium term notes, senior or subordinated notes and classes of preferred or common stock. Upon liquidation, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings will receive a distribution of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock or both. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future offerings reducing the market price of our common stock and diluting their proportionate ownership.

Market interest rates may have an effect on the value of our common stock.

One of the factors that investors may consider in deciding whether to buy or sell our common stock is our dividend distribution rate as a percentage of our share price, relative to market interest rates. If market interest rates continue to increase, prospective investors may desire a higher yield on our common stock or seek securities paying higher dividends or yields. It is likely that the public valuation of our common stock will be based primarily on our earnings and cash flows and not from the underlying appraised value of the properties themselves. As a result, interest rate fluctuations and capital market conditions can affect the market value of our common stock. For instance, if interest rates continue to rise, it is possible that the market price of our common stock will decrease, because potential investors may require a higher dividend yield on our common stock as market rates on interest-bearing securities, such as bonds, rise.

25

If securities analysts do not publish research or reports about our business or if they downgrade our common stock or our sector, the price of our common stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We do not control these analysts. Furthermore, if one or more of the analysts who do cover us downgrades our shares or our industry, or the stock of any of our competitors, the price of our shares could decline. If one or more of these analysts ceases coverage of our company, we could lose attention in the market, which in turn could cause the price of our common stock to decline.

The failure of any bank in which we deposit our funds could reduce the amount of cash we have available to pay distributions and make additional investments.

The Federal Deposit Insurance Corporation only insures amounts up to $250,000 per depositor. We have cash and cash equivalents and restricted cash deposited in certain financial institutions in excess of federally insured levels. Recently, we have seen the abrupt failure of more than one regional bank. Although we hold cash primarily in the top ten banks in the United States and we did not experience any loss related to the recent bank failures, if any of the banking institutions in which we deposit funds ultimately fails, we may lose amounts of our deposits over federally insured levels. The loss of our deposits could reduce the amount of cash we have available to distribute, to pay down maturing debt, or to invest, and could result in a decline in the value of our stockholders' investment.

ITEM 1B.    UNRESOLVED STAFF COMMENTS

There were no unresolved SEC staff comments as of December 31, 2023.

ITEM 1C.    CYBERSECURITY

Cybersecurity Risk Management and Strategy

To identify and assess material risks from cybersecurity threats, our enterprise risk management program considers cybersecurity threats alongside other company risks as part of our overall risk assessment process. In addition, we perform an external, specific cybersecurity risk assessment every eighteen months. Included in our management of cybersecurity risk is our annual review of our Incident Response Plan/Policy, involving employees from all responsibility levels of the company. Our Chief Financial and Administrative Officer has primary responsibility for overseeing our information systems and information technology resources, including risks from cybersecurity threats. To assist our Chief Financial and Administrative Officer in discharging these responsibilities, we have a standing management committee to address information technology and cybersecurity risk matters comprised of our Chief Financial and Administrative Officer, the principal of a third-party, managed security service provider (an “MSSP”), our Vice President of Risk Management, our Chief Accounting Officer, our Senior Vice President of Human Resources and certain other members of our information technology staff and property management. This committee meets on a quarterly basis, with additional meetings held as-needed throughout the year, to:

•monitor emerging data protection laws and implement changes to our processes designed to comply with these laws;

•identify and assess material risks from cybersecurity threats;

•provide guidance on our cybersecurity strategy development and implementation;

•ensure that regular risk assessments and appropriate mitigation strategies are in place;

•ensure the performance of regular vulnerability and penetration testing and remediation of findings;

•oversee the implementation and management of cybersecurity-related tools such as security information and event management systems; and

•review relevant service organization controls reports for the MSSP that serves as our Security Operation Center; and

•require training and security awareness programs for our employees.

Our Vice President of Risk Management monitors and tests these initiatives on a periodic basis. Additionally, our Chief Financial and Administrative Officer partners with the MSSP and our information technology staff throughout the organization to manage material risks from cybersecurity threats, as well as to provide managerial and operational support for our information systems and information technology resources on a daily basis.

26

We also maintain an incident response plan to coordinate the actions we take to prepare for, detect, respond to and recover from cybersecurity incidents, which include processes to triage, assess severity for, escalate, contain, investigate, and remediate the incident, as well as to comply with potentially applicable legal obligations and mitigate brand and reputational damage. The incident response plan is tested annually, with tabletop exercises to assess the validity of the plan and to make necessary modifications, as needed, on a bi-annual basis.

We utilize external risk advisory and accounting firms to perform an audit focusing on entity-level, application and information technology general computer controls annually, as well as the full cybersecurity risk assessment mentioned above. Audit results and the risk assessments are reviewed by our Chief Financial and Administrative Officer, the principal of the MSSP, and our Vice President of Risk Management. Any exceptions are addressed with a remediation plan and implemented with appropriate resources. Audit results, risk assessments and remediation plans are discussed with the Audit Committee of the board of directors, who has responsibility for cybersecurity risk oversight, each quarter until all points are fully resolved.

We also identify and oversee cybersecurity risk from third-party service providers through our vendor management policy, which requires increasing levels of due diligence and required insurance coverages in proportion to each provider's access to our information systems.

Although we have never experienced a material information security breach nor have we incurred any expenses related to such a breach, we take a proactive approach to managing information security risk. Our process for managing existing and new service providers evaluates the degree to which such service providers will interface with our systems. This process dictates minimum insurance requirements and increased security documentation and protocols as interaction with our systems increases. We also have an information security training and compliance program which includes cybersecurity updates, notices, reminders, and simulated cyber-attacks emailed to all employees bi-weekly and that all employees are required to participate in at least annually. Further, we have a documented business continuity plan that is updated and tested on an annual basis and we carry an information security risk insurance policy.

See "We face risks related to the occurrence of cyber incidents, or a deficiency in our cybersecurity, which could negatively impact our business by causing a disruption to our operations, a compromise or corruption of our confidential information, and/or damage to our business relationships, all of which could negatively impact our financial results” included as part of the risk factors described in Item 1A of this Annual Report on Form 10-K for additional information on the potential impact any cybersecurity incident may have on our business, results of operations, financial condition and cash flows.

Cybersecurity Governance

The Audit Committee of the board of directors oversees cybersecurity risk and is comprised of three independent members with diverse expertise including, risk management, technology, and finance, equipping them to oversee cybersecurity risks effectively. The chair of our Audit Committee holds a Certificate in Cybersecurity Oversight from the National Association of Corporate Directors and has previous work experience at a large retailer with point-of-sale cybersecurity exposure. The Audit Committee receives quarterly updates summarizing on-going information technology and cybersecurity initiatives from our Chief Financial and Administrative Officer and reviews the results of our annual risk assessment and regular cyber risk assessment upon completion. Any significant issues identified are reported to the Audit Committee of the board of directors on a quarterly basis.

As described above, our management team is responsible for the day-to-day assessment and management of material risks from cybersecurity threats through our Chief Financial and Administrative Officer, our standing management committee on information technology and cybersecurity risk matters and the MSSP. This group would be notified through our Incident Response Plan/Policy and appropriate actions undertaken in accordance with the plan document if a cyber attack were to occur.

Our Vice President of Risk Management is a Certificated Information Systems Auditor (CISA) and a Certified Internal Auditor (CIA) and holds a Certificate in Risk Management Assurance (CRMA). Personnel from the MSSP hold several certifications, including but not limited to: Certified Information Systems Security Professional ("CISSP"); ITIL Foundations; Fortinet Certified Network Security Administration and Professional; Microsoft Certified IT Professional, Technology Specialist, Solutions Associate; and Citrix Certified Administrator/Citrix Presentation Server 4.0. The external risk advisory and accounting firms that we use to perform our audits and assessments described above utilize personnel qualified as one or more of the following to perform our audits and assessments: Certified Information Systems Auditor (CISA), CISSP, Certified Information Security Manager (CISM), and Certified Information Technology Professional (CITP).

PART II

ITEM 5.    MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information and Holders

Our common stock is listed on the New York Stock Exchange under the symbol “PDM.” As of February 16, 2024, there were 7,277 common stockholders of record of our common stock.

Distributions

We intend to make distributions each taxable year equal to at least 90% of our REIT taxable income (not including a return of capital for federal income tax purposes). One of our primary goals is to pay regular quarterly distributions to our stockholders. The amount of distributions paid and the taxable portion thereof in prior periods are not necessarily indicative of amounts anticipated in future periods.

The amount of distributions to common stockholders is determined by our board of directors and is dependent upon a number of factors, including funds deemed available for distribution, based principally on our current and future projected operating cash flows reduced by outstanding debt service and capital requirements necessary to maintain our existing portfolio, our future capital needs, our future sources of liquidity, and the annual distribution requirements necessary to maintain our status as a REIT under the Code. Our board of directors declared a quarterly dividend of $0.21 per common share for the first and second quarter of 2023, and a quarterly dividend of $0.125 per common share for the third and fourth quarter of 2023.

During the year ended December 31, 2023, we had a board-authorized stock repurchase program in place that allowed management to repurchase shares of our common stock when they believed such purchases would be a prudent use of capital. No shares were repurchased during the year ended December 31, 2023. As of December 31, 2023, approximately $150.5 million of share repurchase capacity remained; however, this plan expired in February 2024 with no additional purchases.

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):

	December 31, 2023		December 31, 2022
Capital expenditures for redevelopment/renovations	$	57,630	$	59,435
Other capital expenditures, including building and tenant improvements	100,561		61,924
Total capital expenditures (1)	$	158,191	$	121,359

(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.

34

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

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.

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.

(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

42

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.

(3)Presented net of related operating expenses incurred to earn such management fee revenue.

(4)Acquisitions include 1180 Peachtree Street in Atlanta, Georgia, purchased during the third quarter of 2022.

(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, 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

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

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 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows, and estimated fair values of our financial instruments depend in part upon prevailing market interest rates. Market risk is the exposure to loss resulting from changes in interest rates, foreign currency, exchange rates, commodity prices, and equity prices. As of December 31, 2023, our potential for exposure to market risk includes interest rate fluctuations in connection with borrowings under our $600 Million Unsecured 2022 Line of Credit, the remaining $100 million outstanding on the $200 Million 2022 Unsecured Term Loan Facility, and the $215 Million Unsecured 2023 Term Loan. As a result, the primary market risk to which we believe we are exposed is interest rate risk. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control contribute to interest rate risk, including changes in the method pursuant to which SOFR rates are determined.

Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flow primarily through a low-to-moderate level of overall borrowings, as well as managing the variability in rate fluctuations on our outstanding debt. As such, all of our debt as of December 31, 2023, other than those variable rate facilities mentioned above, is currently based on fixed or effectively-fixed interest rates to hedge against volatility in the credit markets. We do not enter into derivative or interest rate transactions for speculative purposes, as such all of our debt and derivative instruments were entered into for purposes other than trading purposes.

Our financial instruments consist of both fixed and variable-rate debt. As of December 31, 2023, our consolidated principal outstanding for aggregate debt maturities consisted of the following (in thousands):

	2024				2025				2026				2027			2028			Thereafter			Total
Maturing debt:
Variable rate repayments	$	315,000		(2)	$	—			$	59,000		(4)	$	—		$	—		$	—		$	374,000
Variable rate average interest rate (1)	6.71		%		—		%		6.45		%		—		%	—		%	—		%	6.67		%
Fixed rate repayments	$	53,317			$	253,588		(3)	$	3,738			$	3,895		$	781,495		$	600,000		$	1,696,033
Fixed rate average interest rate (1)	4.43		%		4.78		%		4.10		%		4.10		%	8.05		%	2.95		%	5.63		%

(1)See Note 3 to our accompanying consolidated financial statements for further details on our debt structure.

(2)Includes a balance of $100 million on the $200 Million Unsecured Term Loan Facility which was repaid on January 30, 2024. Also includes the $215 Million Unsecured 2023 Term Loan, $190 million of which was repaid on January 30, 2024, with the remaining $25 million extended to January 31, 2025. See Note 3 to our accompanying consolidated financial statements for more details.

(3)Includes the $250 Million Unsecured 2018 Term Loan. The facility has a stated variable rate; however, Piedmont's interest rate swap agreements as of December 31, 2023 effectively fix, exclusive of changes to Piedmont's credit rating, the full principal balance to 4.79% through the maturity date of the loan.

46

(4)Piedmont may extend the term for up to one additional year (through two available six month extensions to a final extended maturity date of June 30, 2027) provided Piedmont is not in default and upon payment of extension fees.

The estimated fair value of our debt above as of December 31, 2023 and 2022 was approximately $2.0 billion and $1.8 billion, respectively. Our interest rate swap agreements in place as of December 31, 2023 and December 31, 2022, respectively, carried a notional amount of $250 million and a weighted-average fixed interest rate of 3.49%, exclusive of our corporate credit rating spread.

As of December 31, 2023, our total outstanding debt subject to fixed, or effectively fixed, interest rates totaling approximately $1.7 billion has an average effective interest rate of approximately 5.63% per annum with expirations ranging from 2024 to 2032. A change in the market interest rate impacts the net financial instrument position of our fixed-rate debt portfolio but has no impact on interest incurred or cash flows for that portfolio.

As of December 31, 2023, we had a $59.0 million outstanding balance on our $600 Million Unsecured 2022 Line of Credit. Our $600 Million Unsecured 2022 Line of Credit currently has a stated rate of Adjusted SOFR plus 1.04% per annum (based on our current corporate credit rating), resulting in a total interest rate of 6.45%. Our $200 Million Unsecured Term Loan Facility had a stated rate of Adjusted SOFR plus 1.25% per annum (based on our current corporate credit rating), resulting in a total interest rate of 6.70%. Our $215 Million Unsecured 2023 Term Loan had a stated rate of Adjusted SOFR plus 1.30% per annum (based on our current corporate credit rating), resulting in a total interest rate of 6.71%.To the extent that we borrow funds in the future under the $600 Million Unsecured 2022 Line of Credit or potential future variable-rate lines of credit, we would have exposure to increases in interest rates, which would potentially increase our cost of debt. Additionally, a 1.0% increase in variable interest rates on our outstanding borrowings as of December 31, 2023 would increase interest expense approximately $3.7 million on a per annum basis.

ITEM 9A.    CONTROLS AND PROCEDURES

Management’s Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

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

Report of Management on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, as a process designed by, or under the supervision of, the principal executive and principal financial officers, or persons performing similar functions, and effected by the board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that:

•pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and disposition of our assets;

47

•provide reasonable assurance that the transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of management and/or members of the board of directors; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of human error and the circumvention or overriding of controls, material misstatements may not be prevented or detected on a timely basis. In addition, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with policies or procedures may deteriorate. Accordingly, even internal controls determined to be effective can provide only reasonable assurance that the information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized, and represented within the time periods required.

Our management has assessed the effectiveness of our internal control over financial reporting at December 31, 2023. To make this assessment, we used the criteria for effective internal control over financial reporting described in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management believes that, as of December 31, 2023, our system of internal control over financial reporting was effective.

Piedmont’s independent registered public accounting firm has issued an attestation report on the effectiveness of Piedmont’s internal control over financial reporting, which appears in this Annual Report.

Changes in Internal Control Over Financial Reporting

There have been no significant changes in our internal control over financial reporting during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 20, 2024, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Piedmont Office Realty Trust, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Piedmont Office Realty Trust, Inc. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes and the schedule listed in the Index at Item 15(a) (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenues - Refer to Note 2 to the financial statements

Critical Audit Matter Description

Rental and tenant reimbursement income consists of revenue from leases with the Company’s tenants, as well as reimbursements for services prescribed by such leases. The Company recognizes fixed base rental payments, as well as any fixed portions of reimbursement income, on a straight-line basis over the term of the related lease. The timing of rental revenue recognition is largely dependent on whether the Company is the owner of tenant improvements at the leased property. In determining whether the Company or the tenant owns such tenant improvements, the Company considers a number of factors, including, among other things: 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

F-2

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 significant residual value that could benefit the landlord at the end of the lease term.

The determination of whether the Company or its tenant owns the tenant improvements and the timing and amount of revenue recognition requires the exercise of significant judgment by management based on the facts and circumstances of the specific lease arrangement and is not based on any one factor. Auditing management’s conclusions with respect to these matters often is complex and requires subjective judgment.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s determination of the owner of the tenant improvements and the related impact on the timing and amount of revenue recognition, included the following, among others:

•We tested the effectiveness of controls over revenue recognition, including the determination of the owner of tenant improvements and the timing and amounts of rental revenues to be recognized over the term of the related lease.

•We selected a sample of lease agreements and performed the following to evaluate the appropriateness of management’s conclusions regarding the owner of the tenant improvements and the timing and amount of revenue recognition:

◦Evaluated the reasonableness and consistency of the factors considered by management to determine the owner of the tenant improvements and compared such factors to the terms in the lease agreement or other supporting documents.

◦Tested tenant improvement costs (including the amounts funded by the Company or the tenant) by reconciling the amounts recorded by the Company to invoices or other supporting documents and evaluated whether the costs were consistent with the terms of the lease agreement and the Company’s ownership determination.

◦Tested the timing and amounts recognized as rental income, including any amortization of deferred revenue or lease incentives, by independently calculating such rental income amounts to be recognized and comparing it to the amounts recorded by the Company.

Valuation of Goodwill – Refer to Note 2 to the financial statements

Critical Audit Matter Description

The Company assesses its goodwill for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate it is more likely than not that the fair value of a reporting unit may be less than its carrying value. If the Company concludes that the fair value of a reporting unit is less than its carrying value, then the Company recognizes an 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). The Company’s 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. Total goodwill as of December 31, 2023, was approximately $53 million. During the year ended December 31, 2023, the Company recorded a goodwill impairment loss of approximately $29 million.

Auditing the goodwill impairment assessment required a high degree of auditor judgment and increased extent of effort due to the significant estimation uncertainty in certain assumptions used to determine the fair value of each reporting unit. Specifically, the capitalization rate and discount rate assumptions selected by the Company to determine the fair value of each reporting unit are inherently subjective, and changes in these assumptions could have a significant impact on a reporting unit’s estimated fair value.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the capitalization rate and discount rate assumptions used in determining the fair value of each of the Company’s reporting units included the following, among others:

•We tested the effectiveness of internal controls related to management’s goodwill impairment evaluation, including those related to the selection of the capitalization rates and discount rates used in the valuation of each reporting unit.

F-3

•We selected a sample of properties and performed the following to evaluate the appropriateness of management’s conclusions regarding the discount rate and terminal cap rate assumptions:

◦We evaluated the reasonableness of the capitalization rates and discount rates used by management to estimate the fair value of its reporting units based on independent market data, focusing on geographic location and other property characteristics.

◦We developed independent estimates of capitalization rates and discount rates and compared those to the rates used by management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2023, 2022, AND 2021

1.    Organization

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

As of December 31, 2023, Piedmont owned 51 in-service office properties and one redevelopment asset, primarily located in major U.S. Sunbelt office markets. As of December 31, 2023, the in-service office properties comprised approximately 16.6 million square feet (unaudited) and were 87.1% leased.

2.    Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements of Piedmont are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Piedmont, Piedmont’s wholly-owned subsidiaries, any variable interest entity ("VIE") of which Piedmont or any of its wholly-owned subsidiaries is considered to have the power to direct the activities of the entity and the obligation to absorb losses/right to receive benefits, or any entity in which Piedmont or any of its wholly-owned subsidiaries owns a controlling interest. In determining whether Piedmont or Piedmont OP has a controlling interest, the following factors, among others, are considered: equity ownership, voting rights, protective rights of investors, and participatory rights of investors.

Piedmont owns a majority interest in four properties through three joint ventures. Two of these joint ventures, 1201 and 1225 Eye Street, NW Associates, own the 1201 and 1225 Eye Street buildings, respectively, in Washington, D.C. The other joint venture, Piedmont-CNL Towers Orlando, LLC, owns CNL Center I and II, in Orlando, Florida. All three joint venture investments are consolidated under the voting model. Accordingly, Piedmont’s consolidated financial statements include the accounts of 1201 Eye Street, NW Associates, LLC, 1225 Eye Street, NW Associates, LLC, and Piedmont-CNL Towers Orlando, LLC.

All inter-company balances and transactions have been eliminated upon consolidation.

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

Use of Estimates

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

F-10

Real Estate Assets

Piedmont classifies its real estate assets as long-lived assets held for use or as long-lived assets held for sale. Held for use assets are stated at cost, as adjusted for any impairment loss, less accumulated depreciation. Held for sale assets are carried at lower of depreciated cost or estimated fair value, less estimated costs to sell. Piedmont generally reclassifies assets as held for sale once a sales contract has been executed and earnest money has become non-refundable.

Amounts capitalized to real estate assets consist of the cost of acquisition or construction, any tenant improvements or major improvements, betterments that extend the useful life of the related asset, and transaction costs associated with the acquisition of an individual asset that does not qualify as a business combination. All repairs and maintenance are expensed as incurred. Additionally, Piedmont capitalizes interest and other costs such as taxes and insurance while the development, or redevelopment, of a real estate asset is in progress.

Piedmont’s real estate assets are depreciated or amortized using the straight-line method over the following useful lives:

Buildings	40 years
Building improvements	5-25 years
Land improvements	20-25 years
Tenant allowances	Lease term
Furniture, fixtures, and equipment	3-10 years
Intangible lease assets	Lease term

Piedmont continually monitors events and changes in circumstances that could indicate that the carrying amounts of the real estate and related intangible assets of operating properties in which Piedmont has an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, management assesses 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 values, 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, management adjusts such assets to the respective estimated fair values and recognizes an impairment loss. Estimated fair values are calculated based on the following information, depending upon availability, in order of preference: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of undiscounted cash flows, including estimated sales value (which is based on key assumptions such as estimated market rents, lease-up periods, estimated lease terms, and capitalization and discount rates) less estimated selling costs.

Fair Value of Assets and Liabilities of Acquired Properties

Upon the acquisition of real properties, Piedmont records the fair value of properties (plus any related acquisition costs) allocated based on relative fair value as tangible assets, consisting of land and building, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based on their estimated fair values. Piedmont's property acquisitions typically qualify as asset acquisitions under Accounting Standards Codification ("ASC") 805, Business Combinations.

The estimated fair values of the tangible assets of an acquired property are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and building based on management’s determination of the estimated fair value of these assets. Management relies on a sales comparison approach using closed land sales and listings in determining the land value, and determines the as-if-vacant estimated fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates the cost to execute similar leases including leasing commissions, legal, and other related costs.

The estimated fair values of above-market and below-market in-place leases are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of market rates for the corresponding in-place leases, measured over a period equal to the remaining terms of the leases, taking into consideration the probability of renewals for any

F-11

below-market leases. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental revenues over the remaining terms of the respective leases.

The estimated fair values of in-place leases include an estimate of the direct costs associated with obtaining the acquired or "in place" tenant, estimates of opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease. The amount capitalized as a direct cost associated with obtaining a tenant includes commissions, tenant improvements, and other direct costs and is estimated based on management’s consideration of current market costs to execute a similar lease. These direct lease origination costs are included in deferred lease costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These lease intangibles are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases.

Gross intangible assets and liabilities, inclusive of amounts classified as real estate assets held for sale, recorded as of December 31, 2023 and 2022, respectively, are as follows (in thousands):

	December 31, 2023		December 31, 2022
Intangible Lease Assets:
Above-Market In-Place Lease Assets	$	868	$	1,147
In-Place Lease Valuation	$	169,786	$	203,927
Intangible Lease Origination Costs (included as component of Deferred Lease Costs)	$	235,820	$	285,777
Intangible Lease Liabilities (Below-Market In-Place Leases)	$	78,736	$	93,372

For the years ended December 31, 2023, 2022, and 2021, respectively, Piedmont recognized amortization of intangible lease costs in the accompanying consolidated statements of operations, as follows (in thousands):

	2023		2022		2021

(1)Included as a component of Deferred Lease Costs in the accompanying consolidated balance sheets.

F-12

Cash and Cash Equivalents

Piedmont considers all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents include cash and short-term investments. The majority of Piedmont’s cash and cash equivalents are held at major commercial banks and at times may exceed the Federal Deposit Insurance Corporation limit of $250,000. Short-term investments consist of investments in money market accounts stated at cost, which approximates estimated fair value, and available-for-sale securities associated with Piedmont's non-qualified deferred compensation program carried at estimated fair value.

Tenant Receivables and Straight-line Rent Receivables

Tenant receivables are comprised of rental and reimbursement billings due from tenants, and straight-line rent receivables representing the cumulative amount of future adjustments necessary to present rental income on a straight-line basis. Piedmont evaluates the collectibility of its operating lease receivables on a tenant/lease-specific basis and recognizes changes in the collectibility assessment of its operating lease receivables as a reduction of rental and tenant reimbursement revenues.

Allowance for Doubtful Accounts

As detailed above, Piedmont records contra-revenue adjustments to reduce tenant and straight-line rent receivables to their net realizable value when collectibility is in question. During the year ended December 31, 2020 Piedmont also established an allowance for doubtful accounts due to the general uncertainty regarding collectibility of certain tenant receivables during the COVID-19 pandemic. The majority of this allowance was ultimately not used and was reversed during the two years ended December 31, 2023. A roll forward of the allowance for doubtful accounts for the years ended December 31, 2023, 2022, and 2021 is as follows:

	Balance at Beginning of Period		Additions/Reversals as Decrease/(Increase) to Revenue		Write-offs		Balance at End of Period
Year Ended December 31,
2023	$	1,000	$	(1,000)	$	—	$	—
2022	$	4,000	$	(3,000)	$	—	$	1,000
2021	$	4,553	$	35	$	(588)	$	4,000

Restricted Cash and Escrows

Restricted cash and escrows principally relate to the following types of items:

•escrow accounts held by lenders to pay future real estate taxes, insurance, debt service, and tenant improvements;

•net sales proceeds from property sales held by qualified intermediary for potential Section 1031 exchange;

•earnest money paid in connection with future acquisitions; and

•security and utility deposits paid by tenants per the terms of their respective leases.

Restricted cash and escrows are generally reclassified to other asset or liability accounts upon being used to purchase assets, satisfy obligations, or settle tenant obligations.

Prepaid Expenses and Other Assets

Prepaid expenses and other assets are primarily comprised of the following items:

•prepaid property taxes, insurance and operating costs;

•receivables which are unrelated to tenants, for example, insurance proceeds receivable from insurers related to casualty losses; and

•equipment, furniture and fixtures, and tenant improvements for Piedmont’s corporate office and property management office space, net of accumulated depreciation.

Prepaid expenses and other assets will be expensed as utilized or depreciated in the case of Piedmont's corporate assets. Balances without a future economic benefit are expensed as they are identified.

F-13

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 Piedmont's reporting units. (See Note 14 below for further detail). Piedmont tests the carrying value of the goodwill assigned to each of its reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate 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 its goodwill impairment assessment, Piedmont compares the estimated fair value of each of its reporting units to the reporting unit’s carrying value. If Piedmont concludes that the fair value of a reporting unit is less than its carrying value, then Piedmont 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. Piedmont also makes assumptions 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.

As a result of impairment assessments performed during the years ended December 31, 2023 and 2022 Piedmont determined that portions of its goodwill related to various reporting units were impaired, and recorded goodwill impairment charges in each period as further described in Note 6 below.

Interest Rate Derivatives

Piedmont has periodically entered into interest rate derivative agreements to hedge its exposure to changing interest rates. As of December 31, 2023 and 2022, all of Piedmont's interest rate derivatives were designated as effective cash flow hedges and carried on the balance sheet at estimated fair value. Piedmont reassesses the effectiveness of its derivatives designated as cash flow hedges on a regular basis to determine if they continue to be highly effective and if the forecasted transactions remain highly probable. Piedmont does not use derivatives for trading or speculative purposes.

The changes in estimated fair value of interest rate swap agreements designated as effective cash flow hedges are recorded in other comprehensive income (“OCI”), and subsequently reclassified to earnings when the hedged transactions occur. The estimated fair value of the interest rate derivative agreement is recorded as interest rate derivative asset or as interest rate derivative liability in the accompanying consolidated balance sheets. Amounts received or paid under interest rate derivative agreements are recorded as reductions or additions to interest expense in the consolidated statements of operations as incurred. Additionally, when Piedmont settles forward starting swap agreements, any gain or loss is recorded as accumulated other comprehensive income and is amortized to interest expense over the term of the respective notes on a straight line basis (which approximates the effective interest method). Further, Piedmont classifies cash flows from the settlement of hedging derivative instruments in the same category as the underlying exposure which is being hedged. Settlements resulting from the hedge of Piedmont's exposure to interest rate changes are classified as operating cash flows in the accompanying consolidated statements of cash flows.

Deferred Lease Costs

Deferred lease costs are comprised of costs and incentives incurred to acquire operating leases. In addition to direct costs, deferred lease costs also include intangible lease origination costs related to in-place leases acquired as part of a property acquisition.

Deferred lease costs are amortized on a straight-line basis over the terms of the related underlying leases in the accompanying consolidated statements of operations as follows:

•Approximately $56.1 million, $57.9 million, and $56.4 million of deferred lease costs are included in amortization expense for the years ended December 31, 2023, 2022, and 2021, respectively; and

•Approximately $4.4 million, $4.2 million, and $3.9 million, of deferred lease costs related to lease incentives granted to tenants are included as an offset to rental and tenant reimbursement revenue for the years ended December 31, 2023, 2022, and 2021, respectively.

F-14

Upon receipt of an early lease termination notice, Piedmont recognizes any unamortized deferred lease costs ratably over the revised remaining term of the lease after giving effect to the termination notice. If there is no remaining lease term and no other obligation to provide the tenant space in the property, then any unamortized tenant-specific costs are recognized immediately.

Debt

When mortgage debt is assumed upon the acquisition of real property, Piedmont adjusts the loan to relative fair value with a corresponding adjustment to building and other intangible assets assumed as part of the purchase. The fair value adjustment is amortized to interest expense over the term of the loan using the effective interest method. Amortization of such fair value adjustments was approximately $0, $0, and $0.3 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Piedmont records premiums and discounts on debt issuances as an increase/decrease to the principal amount of the loan in the accompanying consolidated balance sheets, and amortizes such premiums or discounts as a component of interest expense over the life of the underlying loan facility using the effective interest method. Piedmont recorded discount amortization of approximately $0.7 million, $0.6 million and $0.5 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Piedmont presents all debt issuance costs as an offset to the principal amount of debt in the accompanying consolidated balance sheets. Piedmont amortizes these costs to interest expense on a straight-line basis (which approximates the effective interest rate method) over the terms of the related financing arrangements. Piedmont recognized amortization of such costs for the years ended December 31, 2023, 2022, and 2021 of approximately $4.7 million, $2.8 million, and $2.7 million, respectively.

Deferred income

Deferred income is primarily comprised of the following items:

•prepaid rent from tenants;

•tenant reimbursements related to operating expense or property tax expenses which may be due to tenants as part of an annual operating expense reconciliation; and

•tenant improvement allowance overages or improvements funded by the tenant where Piedmont owns the underlying improvements.

Deferred income related to prepaid rents from tenants will be recognized as rental income in the period it is earned. Amounts related to operating expense reconciliations or property tax expense are relieved when the tenant's reconciliation is completed in accordance with the underlying lease, and payment is issued to the tenant. Tenant improvement allowance overages or improvements paid for by the tenant, where Piedmont owns all of the underlying improvements, are recorded as deferred income and amortized on a straight-line basis into rental and tenant reimbursement revenue over the term of the respective leases.

Shares-in-trust

To date, Piedmont has not issued any shares-in-trust; however, under Piedmont’s charter, it has authority to issue a total of 150,000,000 shares-in-trust, which would be issued only in the event that there is a purported transfer of, or other change in or affecting the ownership of, Piedmont’s capital stock that would result in a violation of the ownership limits that are included in Piedmont’s charter to protect its REIT status.

Preferred Stock

To date, Piedmont has not issued any shares of preferred stock; however, Piedmont is authorized to issue up to 100,000,000 shares of one or more classes or series of preferred stock. Piedmont’s board of directors may determine the relative rights, preferences, and privileges of any class or series of preferred stock that may be issued, and can be more beneficial than the rights, preferences, and privileges attributable to Piedmont’s common stock.

F-15

Common Stock

Under Piedmont’s charter, it has authority to issue a total of 750,000,000 shares of common stock with a par value of $0.01 per share. Each share of common stock is entitled to one vote and participates in distributions equally. Piedmont previously had a board-authorized stock repurchase program, which expired in February 2024, under which it repurchased its own shares from time to time in the open market, in accordance with applicable securities laws.

Equity Securities Issued At-The-Market

Under Piedmont's at-the-market stock offering program ("ATM program"), Piedmont may offer and sell shares of its common stock from time to time in “at-the-market” offerings with an aggregate gross sales price of up to $250 million. In connection with the ATM Program, Piedmont may, at its discretion, enter into forward equity sale agreements. The use of a forward equity sale agreement would allow Piedmont to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date, allowing Piedmont to better align such funding with its capital needs. Sales of shares of Piedmont’s common stock through its banking relationships, if any, will be made in amounts and at times to be determined by Piedmont from time to time, but Piedmont has no obligation to sell any of the shares in the offering and may suspend sales in connection with the offering at any time. Sales of Piedmont's common stock under forward equity sale agreements, if undertaken, meet the derivatives and hedging guidance scope exception to be accounted for as equity instruments based on the following assessments: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for Piedmont's own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to Piedmont's own stock.

Underwriting commissions and offering costs incurred in connection with all common equity offerings, including any potential issuances under Piedmont's ATM Program, are reflected as a reduction of additional paid-in capital.

Dividends

As a REIT, Piedmont is required by the Internal Revenue Code of 1986, as amended (the “Code”), to make distributions to stockholders each taxable year equal to at least 90% of its annual taxable income, computed without regard to the dividends-paid deduction and by excluding net capital gains attributable to stockholders (“REIT taxable income”).

Noncontrolling Interest

Noncontrolling interest is the equity interest of consolidated entities that is not owned by Piedmont. Noncontrolling interest is adjusted for the noncontrolling partners' share of contributions, distributions, and earnings (losses) in accordance with the respective partnership agreement. Earnings allocated to such noncontrolling partners are recorded as income applicable to noncontrolling interest in the accompanying consolidated statements of operations.

Revenue Recognition

Piedmont's revenues consist of the following:

Rental and tenant reimbursement income - consists of revenue from leases with Piedmont's tenants, as well as reimbursements for services prescribed by such leases. Piedmont evaluates contracts at commencement to determine if the contract contains a lease. If a contract is determined to contain a lease, the lease is evaluated to determine whether it is an operating, sales-type, or a direct financing lease. All of Piedmont's leases where Piedmont is the lessor are for the lessee's use of space in Piedmont's commercial office properties and are classified as operating leases.

In most lease arrangements, Piedmont finances improvements to leased space and is deemed the owner of the tenant improvements. The determination of who owns the improvements, whether payments to tenants constitute lease incentives or tenant improvements, and the timing of revenue recognition requires the exercise of significant judgment based on the facts and circumstances of the specific lease arrangement and is not based on any one factor. When evaluating whether Piedmont or its tenant owns the improvements, management considers a number of factors, including, among other things:

•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;

F-16

•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.

These tenant improvements are recorded as capital assets by Piedmont and depreciated, typically over the lease term. Payments made by tenants for tenant improvements owned by Piedmont are treated as deferred income and amortized into rental and tenant reimbursement revenue over the lease term.

The timing of rental revenue recognition is largely dependent on our conclusion as to whether Piedmont, or its tenant, is the owner of tenant improvements at the leased property. When Piedmont owns the tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as Piedmont's asset are substantially complete. In some instances, Piedmont may cede control of the leased space to the tenant to be responsible for tenant-owned improvements for the space. In such arrangements, payments made by Piedmont to its tenant are treated as lease incentives and amortized as a reduction to rental and tenant reimbursement revenue over the lease term, which typically begins once the tenant takes possession of the unimproved space.

Lease payments are typically comprised of both fixed base rental payments and separately billed variable lease payments for reimbursement of services performed by Piedmont for the tenant as prescribed by the lease. Fixed base rental payments, as well as any fixed portion of reimbursement income, are recognized on a straight-line basis over the lease term. Tenant reimbursements are recognized as revenue in the period that the related operating cost is incurred. Rents and tenant reimbursements collected in advance are recorded as deferred income in the accompanying consolidated balance sheets.

Property management fee revenue - consists of revenue earned by Piedmont related to operating and managing office properties owned by other third-parties. Such income is within the scope of ASC 606, Revenue from Contracts with Customers ("ASC 606"). Because property management services represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed), property management fee revenue is recognized over time. Any variable consideration transferred as part of these management agreements is recognized in the quarter that the underlying cash receipts are collected, consistent with the allocation objective of allocating the transaction price in an amount that depicts the amount of consideration to which Piedmont expects to be entitled in exchange for transferring the promised service to the customer.

Other property related income - consists of all other property related income from Piedmont's customers (tenants) that is not derived from a contract meeting the definition of a lease and is therefore also within the scope of ASC 606. Examples of such income include parking revenue and income from licenses with unrelated third-parties to place antennae and/or fiber optic cables in or on Piedmont's buildings. These services also represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed); therefore, revenue related to these licenses is also recognized over time.

Gains on the sale of real estate assets, like all non-lease related revenue, are subject to a five-step model requiring that Piedmont identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue upon satisfaction of the performance obligations. In circumstances where Piedmont contracts to sell a property with material post-sale involvement, such involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post-sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized as gain on sale of real estate assets. Property dispositions with no continuing involvement will continue to be recognized upon closing of the sale. In circumstances where Piedmont extends seller financing as part of a sale of real estate assets, Piedmont assesses the collectibility of the notes receivable as of each reporting period end. Notes receivable that are deemed to be uncollectible or fully in default are reduced to their net realizable value, which approximates their fair value.

F-17

Stock-based Compensation

Piedmont has issued stock-based compensation in the form of deferred stock units to its employees and board of directors. For employees, Piedmont's Long-term Incentive Compensation ("LTIC") program is comprised of an annual deferred stock unit component (the "Annual Deferred Stock Unit" program) and a multi-year performance share component (the "Performance Share" program). All awards granted during the three years ended December 31, 2023 pursuant to both the Annual Deferred Stock Unit and Performance Share programs, as well as director's awards, were classified as equity awards and expensed on a straight-line basis over the vesting period, with issuances recorded as a reduction to additional paid in capital. Forfeitures are recorded when they occur. Awards granted prior to the three-year service period (2020-2022) pursuant to the Performance Share component of the LTIC program were classified as liability awards and remeasured at fair value as of the end of each reporting period during the service period, with issuances recorded as a reduction to accrued expense. Compensation expense recognized related to both of these award types is recorded as property operating costs for those employees whose job is related to property operations and as general and administrative expense for all other employees and board of directors in the accompanying consolidated statements of operations.

Net Income/(Loss) Available to Common Stockholders Per Share

Net income/(loss) per share-basic is calculated as net income/(loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income/(loss) per share-diluted is calculated as net income/(loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including the dilutive effect of nonvested restricted stock. The dilutive effect of nonvested restricted stock is calculated using the treasury stock method to determine the number of additional common shares that would become outstanding if the remaining unvested restricted stock awards vested. Further, Piedmont has elected to use the "end of the reporting period" convention when using the treasury stock method to calculate the dilutive effect of any shares issued pursuant to forward equity sale agreements in connection with Piedmont's ATM Program described above. Under this methodology, the assumed sale proceeds are calculated using the closing price of Piedmont's stock as of the end of the respective reporting period.

Income Taxes

Piedmont has elected to be taxed as a REIT under the Code, and has operated as such, beginning with its taxable year ended December 31, 1998. To qualify as a REIT, Piedmont must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income. As a REIT, Piedmont is generally not subject to federal income taxes, subject to fulfilling, among other things, its taxable income distribution requirement. However, Piedmont is subject to federal income taxes related to the operations conducted by its taxable REIT subsidiary which have been provided for in the financial statements. These operations resulted in approximately $39,000, $10,000, and $379,000 in income tax recoveries for the years ended December 31, 2023, 2022, and 2021, respectively, as a component of other income/(expense) in the accompanying consolidated statements of operations. Further, Piedmont is subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in property operating costs in the accompanying consolidated financial statements.

Recent Accounting Pronouncements

Segment Expense Disclosure

The Financial Accounting Standards Board (the "FASB") has issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures ("ASU 2023-07). ASU 2023-07 requires expanded disclosure of significant segment expenses which are regularly provided to the chief operating decision maker ("CODM"); all entities that have a single reportable segment must provide existing segment disclosures; disclosure of the title and position of the CODM; and entities must disclose the amounts and a qualitative description of "other segment items", representing the difference between segment revenue less segment expenses reported in segment profit or loss. ASU 2023-07 is effective for Piedmont beginning with the Form 10-K for the year ended December 31, 2024, and subsequent interim periods thereafter. Piedmont is currently evaluating the potential impact of adoption; however, Piedmont does not anticipate any material impact to its consolidated financial statements as a result of adoption of ASU 2023-07.

Income Tax Disclosure

The FASB has issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures ("ASU 2023-09). ASU 2023-09 requires expanded disclosure of tax information, including a rate reconciliation and the amounts of

Piedmont is currently evaluating the potential impact of adoption; however, Piedmont does not anticipate any material impact to its consolidated financial statements as a result of adoption of ASU 2023-09.

3.    Debt

During the year ended December 31, 2023, Piedmont entered into a new, one-year, $215 million, floating-rate, unsecured term loan facility (the “$215 Million Unsecured 2023 Term Loan”) and issued $600 million in aggregate principal amount of 9.250% senior notes due July 20, 2028 (the “$600 Million Unsecured Senior Notes due 2028”).

The $600 Million Unsecured Senior Notes due 2028 are fully and unconditionally guaranteed by Piedmont. Interest is payable semi-annually on January 20 and July 20 of each year commencing January 20, 2024, and is subject to adjustment if Piedmont's corporate credit rating with either Moody’s Investors Services Inc. or S&P Global Ratings falls below investment grade (i.e. BBB-/Baa3). The $600 Million Unsecured Senior Notes due 2028 are subject to typical covenants that, subject to certain exceptions, include: (a) a limitation on the ability of Piedmont and Piedmont OP to, among other things, incur additional secured and unsecured indebtedness; (b) a limitation on the ability of Piedmont and Piedmont OP to merge, consolidate, sell, lease or otherwise dispose of their properties and assets substantially as an entirety; and (c) a requirement that Piedmont maintain a pool of unencumbered assets.

Also during the year ended December 31, 2023, Piedmont:

•fully repaid its $350 Million Unsecured Senior Notes that matured on June 1, 2023;

•redeemed and repaid (using proceeds from the $600 Million Unsecured Senior Notes due 2028) approximately $350 million of its $400 Million Senior Notes due 2024 through a tender offer, resulting in the recognition of an approximately $0.8 million of loss on early extinguishment of debt; and,

•repaid $100 million of the $200 Million Unsecured 2022 Term Loan Facility, scheduled to mature in December 2024.

On January 30, 2024, Piedmont:

•entered into a new, three-year, $200 Million unsecured syndicated bank term loan, due January 30, 2027 at Adjusted Daily Secured Overnight Financing Rate ("SOFR") plus 130 basis points;

•paid off the remaining $100 million of the $200 Million Unsecured 2022 Term Loan Facility;

•repaid $190 million of the $215 Million Unsecured 2023 Term Loan that was scheduled to mature on January 31, 2024; and,

•extended the remaining $25 million of the $215 Million Unsecured 2023 Term Loan to January 31, 2025.

As a result of the above refinancing activity, as of the date of this filing, Piedmont has approximately $325 million of unsecured debt with final maturities over the next three years.

Finally, during the year ended December 31, 2023, Piedmont amended its $250 million, floating-rate, unsecured term loan facility (the "$250 Million Unsecured 2018 Term Loan") to convert the reference interest rate from LIBOR to SOFR, along with the various other related amendments necessary to affect this conversion.

A summary of Piedmont's consolidated principal outstanding for aggregate debt maturities of its indebtedness as of December 31, 2023, is provided below (in thousands):

2024	$	368,317
2025	253,588
2026	62,738
2027	3,895
2028	781,495

Total	$	2,070,033

Piedmont’s weighted-average interest rate as of December 31, 2023 and 2022, for the aforementioned borrowings was approximately 5.82% and 3.89%, respectively. Piedmont made interest payments on all indebtedness, including interest rate swap cash settlements, of approximately $81.0 million, $66.1 million, and $49.4 million during the years ended December 31, 2023, 2022, and 2021, respectively. Also, Piedmont capitalized interest of approximately $7.0 million, $4.2 million, and $3.7 million for the years ended December 31, 2023, 2022, and 2021, respectively. As of December 31, 2023, Piedmont believes it was in compliance with all financial covenants associated with its debt instruments. See Note 5 for a description of Piedmont’s estimated fair value of debt as of December 31, 2023.

4.    Derivative Instruments

Risk Management Objective of Using Derivatives

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

Cash Flow Hedges of Interest Rate Risk

Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for Piedmont making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

As of December 31, 2023, Piedmont was party to a total of eight interest rate swap agreements which are designated as effective cash flow hedges and fully hedge the variable cash flows covering the entire outstanding balance of the $250 Million Unsecured 2018 Term Loan through the maturity of the loan in March 2025. The maximum length of time over which Piedmont is hedging its exposure to the variability in future cash flows related to these interest rate swap agreements is 15 months.

During the year ended December 31, 2021, Piedmont entered into, and subsequently settled, one forward starting interest rate swap agreement with a notional value of $50 million to hedge the risk of changes in the interest-related cash flows associated with the issuance of the $300 Million Unsecured Senior Notes due 2032 (see Note 3). The settlement resulted in a gain of approximately $0.6 million, which was recorded as accumulated OCI and is being amortized as an offset to interest expense over the following ten years.

F-21

A detail of Piedmont’s interest rate derivatives outstanding as of December 31, 2023 is as follows:

Interest Rate Derivatives:	Number of Swap Agreements	Associated Debt Instrument	Notional Amount (in millions)		Effective Date	Maturity Date
Interest rate swaps	2	$250 Million Unsecured 2018 Term Loan	$	100	3/29/2018	3/31/2025
Interest rate swaps	3	$250 Million Unsecured 2018 Term Loan	75		12/2/2022	3/31/2025
Interest rate swaps	3	$250 Million Unsecured 2018 Term Loan	$	75	12/12/2022	3/31/2025
Total			$	250

Piedmont presents its interest rate derivatives on its consolidated balance sheets on a gross basis as interest rate swap assets and interest rate swap liabilities. A detail of Piedmont’s interest rate derivatives on a gross and net basis as of December 31, 2023 and 2022, respectively, is as follows (in thousands):

Interest rate swaps classified as:	December 31, 2023		December 31, 2022
Gross derivative assets	$	3,032	$	4,183
Gross derivative liabilities	—		—
Net derivative assets	$	3,032	$	4,183

The gain/(loss) on Piedmont's interest rate derivatives, including previously settled forward starting interest rate swaps, that was recorded in OCI and the accompanying consolidated statements of operations as a component of interest expense for the years ended December 31, 2023, 2022, and 2021, respectively, was as follows (in thousands):

Interest Rate Swaps in Cash Flow Hedging Relationships:	2023		2022		2021
Amount of gain recognized in OCI	$	2,626	$	8,202	$	2,994
Amount of previously recorded gain/(loss) reclassified from OCI into Interest Expense	$	3,365	$	(1,273)	$	(2,952)
Total amount of Interest Expense presented in the consolidated statements of operations	$	(101,258)	$	(65,656)	$	(51,292)
Total amount of Loss on Early Extinguishment of Debt presented in the consolidated statements of operations	$	(820)	$	—	$	—

Piedmont estimates that approximately $1.3 million will be reclassified from OCI as a decrease in interest expense over the next twelve months. Piedmont did not recognize any hedge ineffectiveness on its cash flow hedges during the three years ended December 31, 2023.

See Note 5 for fair value disclosures of Piedmont's derivative instruments.

Credit-risk-related Contingent Features

Piedmont has agreements with its derivative counterparties that contain a provision whereby if Piedmont defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Piedmont could also be declared in default on its derivative obligations. If Piedmont were to breach any of the contractual provisions of the derivative contracts, it could be required to settle its liability obligations under the agreements at their termination value of the estimated fair values plus accrued interest. However, as of December 31, 2023, all of Piedmont's interest rate swap agreements are in an asset position. Additionally, Piedmont has rights of set-off under certain of its derivative agreements related to potential termination fees and amounts payable under the agreements, if a termination were to occur.

5.    Fair Value Measurements of Financial Instruments

Piedmont considers its cash and cash equivalents, tenant receivables, notes receivable, restricted cash and escrows, accounts payable and accrued expenses, interest rate swap agreements, and debt to meet the definition of financial instruments. The following table sets forth the carrying and estimated fair value for each of Piedmont’s financial instruments, as well as its level within the GAAP fair value hierarchy, as of December 31, 2023 and 2022, respectively (in thousands):

	December 31, 2023					December 31, 2022
Financial Instrument	Carrying Value		Estimated Fair Value		Level Within Fair Value Hierarchy	Carrying Value		Estimated Fair Value		Level Within Fair Value Hierarchy
Assets:
Cash and cash equivalents (1)	$	825	$	825	Level 1	$	16,536	$	16,536	Level 1

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

Piedmont's debt was carried at book value as of December 31, 2023 and 2022; however, Piedmont's estimate of its fair value is disclosed in the table above. Piedmont uses widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of the debt facilities, including the period to maturity of each instrument, and uses observable market-based inputs for similar debt facilities which have transacted recently in the market. Therefore, the estimated fair values determined are considered to be based on significant other observable inputs (Level 2). Scaling adjustments are made to these inputs to make them applicable to the remaining life of Piedmont's outstanding debt. Piedmont has not changed its valuation technique for estimating the fair value of its debt.

Piedmont’s interest rate swap agreements presented above, and as further discussed in Note 4, are classified as “Interest rate swaps” in the accompanying consolidated balance sheets and were carried at estimated fair value as of December 31, 2023 and 2022. The valuation of these derivative instruments was determined using widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of the derivatives, including the period to maturity of each instrument, and uses observable market-based inputs, including interest rate curves and implied volatilities. Therefore, the estimated fair values determined are considered to be based on significant other observable inputs (Level 2). In addition, Piedmont considered both its own and the respective counterparties’ risk of nonperformance in determining the estimated fair value of its derivative financial instruments by estimating the current and potential future exposure under the derivative financial instruments as of the valuation date. The credit risk of Piedmont and its counterparties was factored into the calculation of the estimated fair value of the interest rate swaps; however, as of December 31, 2023 and 2022, this credit valuation adjustment did not comprise a material portion of the estimated fair value. Therefore, Piedmont believes that any unobservable inputs used to determine the estimated fair values of its derivative financial instruments are not significant to the fair value measurements in their entirety, and does not consider any of its derivatives to be Level 3 financial instruments.

6.    Impairment Charges

Goodwill Impairment Charges

During the years ended December 31, 2023 and 2022, Piedmont considered the decline in its stock price to be an indicator of impairment and performed several interim impairment assessments of its goodwill balance. These assessments involved comparing the estimated fair value of each of its reporting units (see Note 14) to the reporting unit’s carrying value, inclusive of the goodwill balance allocated to the reporting unit. Estimation of the fair value of each reporting unit involved the projection of discounted future cash flows using certain assumptions that are subjective in nature, including assumptions regarding future market rental rates and the number of months it may take to re-lease a property subsequent to the expiration of current lease agreements, as well as future property operating expenses, among other factors.

Based on the interim impairment assessments performed during the years ended December 31, 2023 and 2022, Piedmont determined that the carrying values of its Boston, Minneapolis, New York, and Northern Virginia/Washington D.C. reporting units (inclusive of each segment's assigned goodwill balance) exceeded the estimated fair value of each respective reporting unit and recorded goodwill impairment charges of approximately $29.4 million and $16.0 million, respectively, in the accompanying consolidated statement of operations. As the carrying value (inclusive of the assigned goodwill balance) of the Boston, Minneapolis, and Northern Virginia/Washington D.C. reporting units exceeded the estimated fair value of each respective reporting unit by an amount greater than the goodwill balance assigned to each unit, the charges for the Boston, Minneapolis, and Northern Virginia/Washington D.C. reporting units were equal to the goodwill balance that had been assigned to each segment. As this was not the case for the New York segment, the charge related to the New York reporting unit, was calculated based on the amount by which the carrying amount of the New York segment (inclusive of the assigned goodwill balance) exceeded the fair value of the New York reporting unit.

The fair value measurements used in the evaluations described above are considered to be Level 3 valuations within the fair value hierarchy as defined by GAAP as the measurements involve projections of discounted future cash flows, which are derived from unobservable assumptions, the most subjective of which are capitalization rates and discount rates for each respective reporting unit. The ranges of discount rates and the capitalization rate used for each segment in the above analyses, at the respective time the analyses were performed, were as follows:

		Range of Discount Rates		Range of Capitalization Rates
Reporting Unit	Valuation Date	Low	High	Low	High
Boston	December 31, 2023	8.25%	9.75%	8.25%	9.00%
Minneapolis	September 30, 2023	8.50%	9.25%	8.50%	9.00%
New York	December 31, 2023	9.50%	9.50%	9.00%	9.00%
Northern Virginia/Washington D.C.	December 31, 2022	8.50%	9.50%	8.25%	9.25%

Impairment Losses on Real Estate Assets

Piedmont recorded the following impairment losses on real estate assets for the years ended December 31, 2023, 2022, and 2021 (in thousands):

	2023		2022		2021
9320 Excelsior Boulevard	$	—	$	10,000	$	—
Two Pierce Place	—		—		41,000
Total impairment loss on real estate assets	$	—	$	10,000	$	41,000

Management shortened the intended hold period for each of the above buildings and in doing so, determined that the carrying value would not be recovered from the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. As a result, Piedmont recognized a loss on impairment calculated as the difference between the carrying value of the asset and the estimated fair value less costs to sell. The estimated fair values were determined based on net contract prices with unrelated, third-party purchasers for each respective building. The fair value measurements used in the evaluation of the non-financial assets above are considered to be Level 1 valuations within the fair value hierarchy as defined by GAAP, as there are direct observations and transactions involving the assets by unrelated, third-party purchasers. The Two Pierce Place building was subsequently sold during the year ended December 31, 2022.

7.    Commitments and Contingencies

Commitments Under Existing Lease Agreements

As a recurring part of its business, Piedmont is typically required under its executed lease agreements to fund tenant improvements, leasing commissions, and building improvements. In addition, certain agreements contain provisions that require Piedmont to issue corporate or property guarantees to provide funding for capital improvements or other financial obligations. As of December 31, 2023, Piedmont had one individually significant unrecorded tenant allowance commitment greater than $10 million. These commitments will be capitalized as the related expenditures are incurred.

Contingencies Related to Tenant Audits/Disputes

Certain lease agreements include provisions that grant tenants the right to engage independent auditors to audit their annual operating expense reconciliations. Such audits may result in different interpretations of language in the lease agreements from that made by Piedmont, which could result in requests for refunds of previously recognized tenant reimbursement revenues, resulting in financial loss to Piedmont. There were no such reductions during the three years ended December 31, 2023.

Litigation

Piedmont is from time to time a party to legal proceedings, which arise in the ordinary course of its business. None of these ordinary course legal proceedings are reasonably likely to have a material adverse effect on results of operations or financial condition. Piedmont is not aware of any such legal proceedings contemplated by governmental authorities.

8.    Stock Based Compensation

Annually, the Compensation Committee of Piedmont's Board of Directors has granted deferred stock award units to certain employees at its discretion. Employee awards typically vest ratably over three or four years. In addition, Piedmont's independent directors receive an annual grant of deferred stock award units for services rendered and such awards vest over a one year service period.

Certain management employees' long-term equity incentive program is split between these deferred stock award units described above and a multi-year performance share program whereby actual awards are contingent upon Piedmont's total stockholder return ("TSR") performance relative to the TSR of a peer group of office REITs. The target incentives for these employees, as well as the peer group to be used for comparative purposes, are predetermined by the board of directors, advised by an outside compensation consultant. The number of shares earned, if any, are determined at the end of the multi-year performance period (or upon termination) and vest immediately. In the event that a participant's employment is terminated prior to the end of the multi-year period, in certain circumstances the participant may be entitled to a pro-rated award based on Piedmont's TSR relative performance as of the termination date. The grant date fair value of the multi-year performance share awards is estimated using the Monte Carlo valuation method and is recognized ratably over the performance period.

(2)Includes a special, one-time deferred stock award to Piedmont's Chief Executive Officer effective July 1, 2019, the date of his promotion to the position, which vests in ratable installments over a five year period beginning July 1, 2020.

(3)Estimated based on Piedmont's cumulative TSR for the respective performance period through December 31, 2023. Share estimates are subject to change in future periods based upon Piedmont's relative TSR performance compared to its peer group of office REITs.

During the years ended December 31, 2023, 2022, and 2021, Piedmont recognized approximately $8.1 million, $8.8 million and $11.0 million of compensation expense related to stock awards, of which approximately $8.1 million, $7.7 million and $9.7 million related to the amortization of unvested shares and potential stock awards and the fair value adjustment for liability awards, respectively. During the year ended December 31, 2023, a total of 275,740 shares (net of shares surrendered upon vesting to satisfy required minimum tax withholding obligations) were issued to employees and independent directors. As of December 31, 2023, approximately $11.4 million of unrecognized compensation cost related to unvested and potential stock awards remained, which Piedmont will record in its consolidated statements of operations over a weighted-average vesting period of approximately one year.

9.    Earnings Per Share

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

Net income/(loss) per share-basic is calculated as net income/(loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income/(loss) per share-diluted is calculated as net income/(loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including unvested deferred stock awards. Diluted weighted average number of common shares reflects the potential dilution under the treasury stock method that would occur if the remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Unvested and potential stock awards which are determined to be anti-dilutive are not included in the calculation of diluted weighted average common shares. For each of the years ended December 31, 2023, 2022, and 2021, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of approximately 1,030,824, 421,005, and 1,114,025, respectively.

The following table reconciles the denominator for the basic and diluted earnings per share computations shown on the consolidated statements of income for the years ended December 31, 2023, 2022, and 2021, respectively (in thousands):

	2023	2022	2021
Weighted-average common shares—basic	123,659	123,351	123,978

Weighted-average common shares—diluted	123,659	123,524	123,978

10.    Operating Leases

Piedmont’s real estate assets are leased to tenants under operating leases for which the terms vary, including certain provisions to extend the lease term, options for early terminations subject to specified penalties, and other terms and conditions as negotiated. Piedmont retains substantially all of the risks and benefits of ownership of the real estate assets leased to tenants. Amounts required as security deposits vary depending upon the terms of the respective leases and the creditworthiness of the tenant; however, generally they are not significant. Exposure to credit risk exists to the extent that tenant receivables exceed this amount. Security deposits liabilities related to tenant leases are included in accounts payable, accrued expenses, and accrued capital expenditures in the accompanying consolidated balance sheets.

The future minimum rental income from Piedmont’s investment in real estate assets under non-cancelable operating leases as of December 31, 2023 is presented below (in thousands):

Years ending December 31:
2024	$	424,131
2025	401,657

Total Rental and Tenant Reimbursement Revenue	$	555,313	$	545,741	$	514,619

Operating leases where Piedmont is the lessee relate primarily to office space in buildings owned by third parties and managed by Piedmont. Piedmont's right to use asset and corresponding lease liability, using Piedmont's incremental borrowing rate as the lease discount rate, was approximately $0.1 million for the year ended December 31, 2023 and approximately $0.2 million for the year ended December 31, 2022. For the three years ended December 31, 2023, Piedmont recognized approximately $0.1 million of operating lease costs, respectively. As of December 31, 2023, the lease term of Piedmont's right of use asset is one year, and the discount rate is 3.86%.

11.    Property Dispositions and Assets Held for Sale

14.    Segment Information

Piedmont's President and Chief Executive Officer has been identified as Piedmont's chief operating decision maker ("CODM"), as defined by GAAP. The CODM evaluates Piedmont's portfolio and assesses the ongoing operations and performance of its properties utilizing the following geographic segments: Atlanta, Dallas, Orlando, Northern Virginia/Washington, D.C., Minneapolis, New York, and Boston. These operating segments are also Piedmont’s reportable segments. As of December 31, 2023, Piedmont also owned two properties in Houston that do not meet the definition of an operating or reportable segment as the CODM does not regularly review these properties for purposes of allocating resources or assessing performance. Further, Piedmont does not maintain a significant presence or anticipate further investment in this market. These two properties are the primary contributors to accrual-based net operating income ("NOI") included in "Other" below. During the periods presented, there have been no material inter-segment transactions. The accounting policies of the reportable segments are the same as Piedmont's accounting policies.

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

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

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

DEFERRED STOCK AWARD AGREEMENT

This Deferred Stock Award Agreement (this “Agreement”) evidences a Deferred Stock Award made pursuant to the Piedmont Office Realty Trust, Inc. Second Amended and Restated 2007 Omnibus Incentive Plan (the “Plan”) to ______________, who shall be referred to as “Employee,” with respect to ______________ phantom stock units (“Units”), each Unit corresponding to one share of common stock of Piedmont Office Realty Trust (“Stock”). This Deferred Stock Award is made effective as of ______________, which shall be referred to as the “Award Date.”

PIEDMONT OFFICE REALTY TRUST

TERMS AND CONDITIONS

§ 1.    Plan and Deferred Stock Award Agreement. Employee’s right to receive any or all of the shares of Stock subject to this Deferred Stock Award is subject to all of the terms and conditions set forth in this Agreement and in the Plan. If a determination is made that any term or condition set forth in this Agreement is inconsistent with the Plan, the Plan shall control. All of the capitalized terms not otherwise defined in this Agreement shall have the same meaning as in the Plan. A copy of the Plan will be made available to Employee upon written request to the Chief Financial Officer of the Company.

§ 2.    Stockholder Rights. During the deferral period, Employee shall have no rights as a stockholder with respect to any shares of Stock subject to this Deferred Stock Award. Employee’s rights as a stockholder shall only arise when employee’s Units have become vested and nonforfeitable under § 3 and such shares of Stock have been transferred on the Company’s books and records to Employee.

§ 3.    Vesting and Forfeiture.

(a)    General Vesting Rule. Subject to § 3(b), Employee’s Units will vest and become nonforfeitable as follows:

(1)    one-fourth of the Units will vest and become nonforfeitable on the first anniversary of the Award Date, provided Employee has remained continuously employed by the Company or a Subsidiary through such date.

(2)    another one-fourth of the Units will vest and become nonforfeitable on each subsequent anniversary of the Award Date thereafter until Employee becomes fully vested in all Units, provided Employee has remained

continuously employed by the Company or a Subsidiary from the Award Date through the respective anniversary of the Award Date.

(b)    Special Vesting Rules.

(1)    All of Employee’s Units automatically will vest and become nonforfeitable if (after Employee has signed this Deferred Stock Award Agreement) (A) Employee incurs a Termination of Service with the Company or a Subsidiary as a result of Employee’s (i) death, (ii) Permanent Disability (as defined in § 3(d)(4)), (iii) Lay Off (as defined in § 3(d)(2)), (iv)Retirement (as defined in § 3(d)(3)), (v) termination by the Company or a Subsidiary without Cause or (B) there is a Change in Control (as defined in § 3(d)(5)).

(2)    An Employee on an approved leave of absence, as described in Section 16(b) of the Plan, other than due to vacation, jury duty or military leave (an “Approved Leave”), will not continue to vest in any Units during or after such Approved Leave, provided, however, that if immediately after the end of such Approved Leave Employee returns to Active Service (as defined in § 3(d)(1) with the Company or its Subsidiaries for a continuous period of at least 90 days, such Employee will be vested in such Units in the same amount as such Employee would have been vested if such Employee had never taken such Approved Leave. For the avoidance of doubt, an Employee on an approved leave of absence due to vacation, jury duty or military leave shall continue to vest in any Units during such leave in accordance with § 3(a) until the Employee has a Termination of Service.

(c)    Forfeiture. If Employee incurs a Termination of Service with the Company or a Subsidiary for any reason before Employee’s interest in all of the Units have become vested and nonforfeitable under this § 3, after including any vesting under the Special Vesting Rules as described in § 3(b), then Employee shall forfeit all Units which have not become so vested and nonforfeitable before the date of such Termination of Service.

(d)    Definitions.

(1)    Active Service. The term “Active Service” under § 3(b) means an Employee that is working Employee’s typical regular schedule at the Company and not on an Approved Leave.

(2)    Lay Off. The term “Lay Off” under § 3(b) means the elimination of Employee’s job with the Company or a Subsidiary resulting in a Termination of Service if there is no offer of continued employment at a comparable position.

(3)    Retirement. The term “Retirement” under §3(b) means a Termination of Service with the Company or a Subsidiary after Employee reaches age 62, other than for Cause.

(4)    Permanent Disability. The term “Permanent Disability” under § 3(b) means Employee is awarded long-term disability benefits under the Company’s long-term disability plan.

(5)    Change in Control. The term “Change in Control” shall have the meaning given to such term in the Plan; provided, however, that, if Employee shall attain the age of 62 on or prior to the vesting of any tranche of the Deferred Stock Award pursuant to § 3(a)(2), with respect to any such tranche, the term

“Change in Control” means a “change in control event,” as defined in Section 14(c)(i) of the Plan that also qualifies as a “change in control event” as defined in Treas. Reg. Section 1.409A-3(i)(5)(i).

(e)    Termination of Service. Employee shall be treated as incurring a Termination of Service for employment purposes as of the last date Employee is paid Employee’s normal salary for services actually rendered, exclusive of any period covered by severance.

§ 4.    Settlement; Tax Liability. Employee shall have the right (subject to applicable tax withholdings effected in accordance with Section 13 of the Plan) to receive shares of Stock subject to this Deferred Stock Award on the date Employee’s Units vest and become nonforfeitable under § 3; provided, however, that, if Employee is age 62 or older, Employee shall have the right to receive shares of Stock subject to this Deferred Stock Award upon the earlier of the applicable vesting date, as set forth in § 3(b), or Employee’s Termination of Service other than a Termination of Service for Cause. Employee may (in accordance with Section 13 of the Plan) choose to make payment of the applicable tax withholdings by 1) a cash payment and thereby receive the total number of shares Employee has the right to receive, or 2) a reduction in Stock pursuant to Section 13 (b) of the Plan.

The Company shall cause any shares of Stock which Employee has a right to receive under § 3 (subject to applicable tax withholdings effected in accordance with Section 13 of the Plan) to be transferred to Employee on the Company’s books and records and delivered to Employee within sixty (60) days after the date on which Employee has the right to receive such shares, the specific date of such transfer to be determined by the Committee. Notwithstanding the foregoing, if Employee’s Termination of Service due to Retirement qualifies as a “separation from service” within the meaning of Code Section 409A and Employee is a “specified employee” within the meaning of Code Section 409A on such Termination of Service, settlement under this § 4 will be delayed until the expiration of the Delay Period in accordance with § 13.

During the period Employee is employed by the Company or a Subsidiary, shares received by Employee under this Agreement, as well as any other shares of Company stock owned by Employee, will be subject to certain trading “blackout” periods (which prohibit the sale or purchase of Company shares). Blackout periods can relate to the announcement of Company earnings or any other material, non-public information. Additionally, shares of Company stock held by Employees may be subject to “lock-up” agreements (which will prohibit the sale by Employees of Company stock for specified periods) as part of offerings of new Company shares on a public exchange.

Anything to the contrary notwithstanding, instead of distributing shares of Stock subject to this Deferred Stock Award, Company may, in its sole discretion, elect to make a lump sum cash payment to Employee equal to the number of shares of Stock to which Employee would otherwise be entitled to receive under this Agreement, multiplied by the Fair Market Value of a share of Stock determined on the date Employee’s Units vest and become nonforfeitable under § 3. Subject to applicable tax withholdings, such lump sum cash payment will be paid to Employee within sixty (60) days after Employee’s Units vest and become nonforfeitable under § 3.

§ 5.    Dividend Equivalents. Each Unit granted hereunder is granted in tandem with a corresponding right to receive an amount equal to each cash and stock dividend that is made by the Company in respect of a share of Stock corresponding to such Unit (a “Dividend Equivalent”). Any such amounts shall be accrued, and shall be paid in a single

lump sum within sixty (60) days after the date on which Employee has the right to receive such share of Stock, the specific date of such transfer to be determined by the Committee in accordance with § 4. Any such Dividend Equivalent shall terminate upon the forfeiture of, or the payment with respect to such Unit, as applicable. Any Dividend Equivalents will be treated as separate payments from the underlying Units for purposes of Section 409A.

§ 6.    Nontransferable. No rights under this Agreement shall be transferable by Employee, except as provided in Section 12 of the Plan.

§ 7.    Other Laws. The Company shall have the right to refuse to transfer shares of Stock subject to this Deferred Stock Award to Employee if the Company acting in its absolute discretion determines that the transfer of such shares is (in the opinion of the Company’s legal counsel) likely to violate any applicable law or regulation.

§ 8.    No Right to Continue Employment or Service. Neither the Plan , this Agreement, nor any related material shall give Employee the right to continue in the employment or other service of the Company or a Subsidiary or shall adversely affect the right which the Company or any Subsidiary has under applicable law to terminate Employee’s employment with or without cause at any time.

§ 9.    Clawback/Recoupment. Notwithstanding any other provision of this Agreement, the Deferred Stock Award shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) the Company's Clawback Policy and any other clawback, forfeiture or other similar policy adopted by the Board or the Committee and as in effect from time to time; and (ii) applicable law or stock exchange listing requirement. By accepting the Deferred Stock Award, Employee is deemed to have acknowledged and consented to the Company’s Clawback Policy and the Company's application, implementation and enforcement of any clawback, forfeiture or other similar policy adopted by the Board or the Committee, whether adopted prior to or following the date of the Award Date, and any provision of applicable law or stock exchange listing requirement relating to reduction cancellation, forfeiture or recoupment, and to have agreed that the Company may take such actions as may be necessary to effectuate any such policy, requirement or applicable law, without further consideration or action.

§ 10.    Governing Law. The Plan and this Agreement shall be governed by the laws of the State of Maryland, applied without regard to conflicts of law principles.

§ 11.    Binding Effect. This Agreement shall be binding upon the Company and Employee and their respective heirs, executors, administrators and successors.

§ 12.    Headings and Sections. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. All references to sections (§) in this Agreement shall be to sections (§) of this Agreement, unless reference to a section of the Plan is specifically made.

§ 13.    409A Compliance. The parties intend that payments under this Agreement comply with or be exempt from Code Section 409A and the Company shall have complete discretion to interpret and construe this Agreement and any associated documents in any manner that establishes an exemption from (or compliance with) the requirements of Code Section 409A. If for any reason, such as imprecision in drafting, any provision of this Agreement does not accurately reflect its intended establishment of an exemption from (or compliance with) Code Section 409A, as demonstrated by consistent interpretations or other evidence of intent, such provision shall be considered

ambiguous as to its exemption from (or compliance with) Code Section 409A and shall be interpreted by the Company in a manner consistent with such intent, as determined in the discretion of the Company. A termination of employment or other Termination of Service shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Code Section 409A upon or following a termination of employment or other Termination of Service unless such termination is also a “separation from service” within the meaning of Code Section 409A, and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment,” “Termination of Service” or like terms shall mean a “separation from service” from the Company. The determination of whether and when a separation from service has occurred for proposes of this Agreement shall be made in accordance with the presumptions set forth in Section 1.409A-1(h) of the Treasury Regulations. Any provision of this Agreement to the contrary notwithstanding, if at the time of Employee’s separation from service, the Company determines that Employee is a “specified employee,” within the meaning of Code Section 409A, then to the extent any payment that Employee is entitled to under this Agreement on account of Employee’s separation from service would be considered nonqualified deferred compensation under Code Section 409A, such payment shall be paid at the date which is the earlier of (i) six (6) months and one day after Employee’s separation from service and (ii) the date of Employee’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this §13 shall be paid to Employee in a lump-sum. The Company makes no representation or warranty and shall have no liability to Employee or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Code Section 409A, but do not satisfy an exemption from, or the conditions of, Code Section 409A.

Employee has signed this Agreement to evidence Employee’s acceptance of this Deferred Stock Award and all of the terms and conditions of such Award.

(c)    Special Vesting Rules.

(1)    All of Employee’s Units automatically will vest and become nonforfeitable if (after Employee has signed this Deferred Stock Award Agreement) (A) Employee incurs a Termination of Service with the Company or a Subsidiary as a result of Employee’s (i) death, (ii) Permanent Disability (as defined in § 3(e)(4)), (iii) Lay Off (as defined in § 3(e)(2)), (iv)Retirement (as defined in § 3(e)(3)), (v) termination by the Company or a Subsidiary without Cause (or (B) there is a Change in Control (as defined in § 3(e)(5)).

(2)    An Employee on an approved leave of absence, as described in Section 16(b) of the Plan, other than due to vacation, jury duty or military leave (an “Approved Leave”), will not continue to vest in any Units during or after such Approved Leave, provided, however, that if immediately after the end of such Approved Leave Employee returns to Active Service (as defined in § 3(e)(1) with the Company or its Subsidiaries for a continuous period of at least 90 days, such Employee will be vested in such Units in the same amount as such Employee would have been vested if such Employee had never taken such Approved Leave. For the avoidance of doubt, an Employee on an approved leave of absence due to vacation, jury duty or military leave shall continue to vest in any Units during such leave in accordance with § 3(a) until the Employee has a Termination of Service.

(d)    Forfeiture. If Employee incurs a Termination of Service with the Company or a Subsidiary for any reason before Employee’s interest in all of the Units have become vested and nonforfeitable under this § 3, after including any vesting under the Special Vesting Rules as described in § 3(c), then Employee shall forfeit all Units which have not become so vested and nonforfeitable before the date of such Termination of Service.

Reg. Section 1.409A-3(i)(5)(i).

(f)    Termination of Service. Employee shall be treated as incurring a Termination of Service for employment purposes as of the last date Employee is paid Employee’s normal salary for services actually rendered, exclusive of any period covered by severance.

Any Dividend Equivalents will be treated as separate payments from the underlying Units for purposes of Section 409A.

§ 6.    Nontransferable. No rights under this Agreement shall be transferable by Employee, except as provided in Section 12 of the Plan.

§ 7.    Other Laws. The Company shall have the right to refuse to transfer shares of Stock subject to this Deferred Stock Award to Employee if the Company acting in its absolute discretion determines that the transfer of such shares is (in the opinion of the Company’s legal counsel) likely to violate any applicable law or regulation.

§ 8.    No Right to Continue Employment or Service.

§ 9.    Clawback/Recoupment.

The parties intend that payments under this Agreement comply with or be exempt from Code Section 409A and the Company shall have complete discretion to interpret and construe this Agreement and any associated documents in any manner that establishes an exemption from (or compliance with) the requirements of Code Section 409A. If for any reason, such as imprecision in drafting, any provision of this Agreement does not accurately reflect its intended establishment of an exemption from (or compliance with) Code Section 409A, as demonstrated by consistent interpretations or other evidence of intent, such provision shall be considered ambiguous as to its exemption from (or compliance with) Code Section 409A and shall be interpreted by the Company in a manner consistent with such intent, as determined in the discretion of the Company.

The parties intend that payments under this Agreement comply with or be exempt from Section 409A and the Company shall have complete discretion to interpret and construe this Agreement and any associated documents in any manner that establishes an exemption from (or compliance with) the requirements of Section 409A.

§ 3.    Performance Level & Payouts.

(a)    Determination of Payout. The Performance Levels and percentage of the Target Amount earned by an Participant for a Performance Cycle will be determined based upon the Company’s Total Shareholder Return (“TSR”) relative to the TSR of the companies in the Peer Group. Following the end of the Performance Cycle, the Committee shall review, and in its sole discretion, determine the extent to which the Performance Levels were in fact satisfied for the Performance Cycle, if at all. Based upon the Company’s Peer Group Percentile Ranking, an Participant will earn a percentage of the Target Amount as set forth in the following chart:

Performance Level	Peer Group Percentile Ranking	Percentage of Target Amount Payable
Maximum	75th percentile or above	200%
Target	Median	100%
Threshold	25th percentile	50%
Below Threshold	below 25th percentile	0%

If the Peer Group Percentile Ranking is between the Threshold and Target Performance Levels or between the Target and Maximum Performance Levels, the percentage of Target Amount earned shall be determined by linear interpolation. Notwithstanding the foregoing, if the Peer Group Percentile Ranking is below the Threshold Performance Level, but the Committee determines that the Company’s absolute TSR for the Performance Cycle was 10% or greater, then 50% of the Target Amount will be payable to Participant. In all cases, the shares of Stock payable with respect to the Performance Cycle shall be a whole number, and any fractional shares shall be rounded to the nearest whole number by rounding-down for fractions less than one-half and rounding-up for fractions equal to or greater than one-half. No cash settlements shall be made with respect to fractional shares eliminated by rounding.

(b)    Absolute TSR Modifier.Notwithstanding anything to the contrary contained in § 3(a), if (i) the Company’s absolute TSR for the Performance Cycle is negative, and (ii) the relative Performance Level for the applicable Performance Cycle is determined to be above the Target Performance Level, the Percentage of the Target Amount Payable shall be reduced according to the following schedule:

Absolute TSR for the Performance Cycle	Reduction in Percentage of Target Amount Payable
-0.01%	10%
<= -15.0%	30%
The absolute TSR modifier will reduce payouts on a linear basis between -10% and -30%, but in no event shall the resulting payout be reduced to less than the Performance Share Award that is payable at the Target Performance Level.

The adjustment in this § 3(b) shall not apply if the relative Performance Level for the applicable Performance Cycle is determined to be at or below the Target Performance Level.

(c)    Definitions.

(i)    Average Price. The term “Average Price” means, with respect to the beginning of a Performance Cycle, the average of the Closing Stock Price for the last 10 trading days preceding the start of the applicable Performance Cycle and the first 10 trading

days of the applicable Performance Cycle, and with respect to the end of an Performance Cycle, the average of the Closing Stock Price for the last 10 trading days preceding the end of the applicable Performance Cycle and the first 10 trading days after the end of the applicable Performance Cycle. Notwithstanding the forgoing, in the event an Participant has a Termination of Service during a Performance Cycle in accordance with § 3(d), Average Price on the date of Participant’s Termination of Service means the average of the Closing Stock Price for the last 10 trading days preceding the date of Participant’s Termination of Service and the first 10 trading days following the date of Participant’s Termination of Service.

(ii)    Closing Stock Price. The term “Closing Stock Price” means, with respect to Stock, the closing sales price per share on the applicable date quoted on the NYSE, or if there are no sales on such date, for the last preceding date on which there were sales of Stock, as determined by the Committee. With respect to the stock of a company in the Peer Group, “Closing Stock Price” means, the closing sales price per share on the applicable date as quoted or reported on such national securities exchange or NASDAQ, or if there are no sales on such date, for the preceding date on which there were sales of stock, as determined by the Committee.

(iii)    Good Reason. The term “Good Reason” means, unless otherwise specified in Participant’s employment agreement, any of the following: (A) the failure of the Company to pay or cause to be paid Participant’s base salary or annual bonus when due; (B) a material diminution in Participant’s status, including, title, position, duties, authority or responsibility; (C) a material adverse change in the criteria to be applied by the Company with respect to Participant’s target annual bonus as compared to the prior fiscal year (unless Participant has consented to such criteria); (D) the relocation of the Company’s executive offices to a location outside of the Atlanta, Georgia metropolitan area without the consent of Participant; (E) the failure to provide Participant with incentive awards that are reasonably and generally comparable to awards granted to other executive officers (other than the CEO) of the Company; or (F) the occurrence of a Change in Control. Notwithstanding the foregoing, (1) Good Reason (a) shall not be deemed to exist unless Participant gives to the Company a written notice identifying the event or condition purportedly giving rise to Good Reason within ninety (90) days after the time at which Participant first becomes aware of the event or condition and (b) shall not be deemed to exist at any time after the Board has determined that there exists an event or condition which could serve as the basis of a termination of Participant’s employment for Cause so long as the Board gives notice to Participant of such determination within thirty (30) days of such determination and such notice is given within one hundred and twenty (120) days after the time at which the Board first becomes aware of the event or conditions constituting Cause; and (2) if there exists an event or condition that constitutes Good Reason, the Company shall have thirty (30) days from the date notice of Good Reason is given to cure such event or condition and, if the Company does so, such event or condition shall not constitute Good Reason hereunder; and if the Company does not cure such event or condition within such 30-day period, Participant shall have ten (10) business days thereafter to give the Company notice of termination of employment on account thereof

(specifying a termination date no later than ten (10) days from the date of such notice of termination).

(iv)    Participant. means an employee, consultant, or Non-Employee Director of the Company, as selected by the Committee in its discretion.

(v)    Peer Group. The term “Peer Group” means the peer group of REIT companies selected by the Committee.

(vi)    Peer Group Percentile Ranking. The term “Peer Group Percentile Ranking” means a comparison of the Company’s TSR to the TSR of other companies in the Peer Group, expressed on a percentile basis.

(vii)    Performance Level. The term “Performance Level” means the Threshold, Target or Maximum Performance Level specified in § 3(a).

(viii)    Performance Cycle. The term “Performance Cycle” means the three-year period beginning on January 1 of the calendar year with respect to which a Performance Share Award is granted.

(ix)    Permanent Disability. The term “Permanent Disability” means the Participant is awarded long-term disability benefits under the Company’s long-term disability plan; provided, however, that if the Performance Share Award is subject to Section 409A of the Code, the term “Permanent Disability” shall have the meaning set forth in Section 409A(a)(2)(c) of the Code.

(x)    Retirement. The term “Retirement” under § 3(d) means a Termination of Service with the Company or a Subsidiary after Participant reaches age 62, other than for Cause.

(xi)    Target Amount. The term “Target Amount” means the number of shares of the Stock with respect to which the Performance Share Award relates assuming achievement of the Target Performance Level. The Target Amount shall be determined by dividing the dollar value established by the Committee with respect to an Participant’s Performance Share Award by the closing price of the Stock on the Award Date.

(xii)    Total Shareholder Return. The term “Total Shareholder Return,” or “TSR,” means the Average Price at the end of a Performance Cycle, minus the Average Price at the beginning of a Performance Cycle, plus any dividends paid during the Performance Cycle, all divided by the Average Price at the beginning of the Performance Cycle; provided, however, that if an Participant terminates employment during a Performance Cycle in accordance with § 3(d), TSR means the Average Price on the date of Participant’s termination of employment, minus the Average Price at the beginning of Performance Cycle, plus any dividends paid during the Performance Cycle until the date of Participant’s termination of employment, all divided by the Average Price at the beginning of the Performance Cycle. If, during a Performance Cycle a Peer Group company (A) is acquired by or merged into another entity, and in either case is not the surviving entity following such merger or acquisition; (B) ceases to be a publicly-traded REIT as the result of a transaction to go private; or (C) publicly announces its intention to change its investment thesis to an asset class other than office, the Peer Group company, upon approval by the Committee, shall be removed from the Peer Group. If, during a Performance Cycle, a Peer Group company declares bankruptcy or is delisted from the securities exchange on which it is traded, such Peer Group company’s TSR shall be set at -100%.

(d)    Termination of Service. Except as otherwise provided in this Section § 3(d), Participant shall not be entitled to any portion of the Performance Share Award if Participant incurs a

Termination of Service before the end of the Performance Cycle. Participant shall be treated as incurring a Termination of Service for employment purposes as of the last date Participant is paid Participant’s normal salary for services actually rendered, exclusive of any period covered by severance. Notwithstanding the foregoing, in the event of Participant’s Termination of Service during a Performance Cycle due to (i) termination by the Company without Cause or by Participant for Good Reason, (ii) Participant’s death or Permanent Disability, (iii) the expiration of Participant’s employment agreement due to non-renewal by the Company, (iv) Retirement or (v) a Change in Control, Participant will be entitled to payment of a portion of Participant’s Performance Share Award for such Performance Cycle based on the Company’s TSR relative to the TSR of the companies in the Peer Group determined as of the date of Participant’s Termination of Service. The percentage of the Target Amount earned pursuant to § 3 will then be multiplied by a fraction, the numerator of which equals the number of days during such Performance Cycle that such Participant was actively employed by the Company, and the denominator of which equals 1,095 days, or total days in the Performance Cycle. Such payment will be paid by the Company 90 days after such Participant’s Termination of Service.

(e)    [Special Vesting. A Participant on an approved leave of absence, as described in Section 16(b) of the Plan, other than due to vacation, jury duty or military leave (an “Approved Leave”) at the end of the Performance Cycle will not vest and earn the percentage (if any) of Participant’s Performance Share Award during or after such Approved Leave, provided, however, that if immediately after the end of such Approved Leave Participant returns to Active Service with the Company or its Subsidiaries for a continuous period of at least 90 days, such Participant will be vested in and earn the percentage of Participant’s Performance Share Award in the same amount as such Participant would have if such Participant had not been on Approved Leave at the end of the Performance Cycle. For purposes of this § 3(e), “Active Service” means a Participant that is working Participant’s typical regular schedule at the Company and not on an Approved Leave. For the avoidance of doubt, a Participant on an approved leave of absence due to vacation, jury duty or military leave at the end of the Performance Cycle shall earn the percentage (if any) of Participant’s Performance Share Award that is earned with respect to a Performance Cycle on such date in accordance with § 3.]

§ 4.    Settlement; Tax Liability. Subject to § 3(d) hereof, the percentage (if any) of Participant’s Performance Share Award that is earned with respect to a Performance Cycle as provided in § 3 hereof shall be paid by the Company in the calendar year after the end of such Performance Cycle [or, if applicable, the calendar year vested and earned in accordance with § 3(e)]. Payments hereunder shall be made in shares of Stock, cash, or a combination thereof, in accordance with the Plan, as determined by the Committee in its sole discretion. Notwithstanding the foregoing, if Participant’s Termination of Service due to Retirement qualifies as a “separation from service” within the meaning of Code Section 409A and Participant is a “specified employee” within the meaning of Code Section 409A on such Termination of Service, settlement under this § 4 will be delayed until the expiration of the Delay Period in accordance with §15.

§ 5.    Holding Period. Corporate officers are required to hold any shares of Stock transferred to Participant accordance with § 4 for a minimum period of twelve (12) months before the shares of Stock can be sold, transferred, pledged, assigned or otherwise disposed of, except if the corporate officer incurs a Termination of Service.

§ 6.    Dividend Equivalents. The Performance Share Award granted hereunder is granted in tandem with a corresponding right to receive an amount equal to each cash and stock dividend that is made by the Company in respect of a share of Stock corresponding to such Performance Share Award (a “Dividend Equivalent”) that has a record date during the Performance Cycle.

Any such amounts shall be accrued, and, to the extent the portion of the Performance Share Award to which such Dividend Equivalent relates becomes earned and vested,shall be paid in a single lump sum within sixty (60) days after the date on which Participant has the right to receive such share of Stock, the specific date of such transfer to be determined by the Committee in accordance with § 4. Any such Dividend Equivalent shall terminate upon the forfeiture of, or the payment with respect to such Unit, as applicable. Any Dividend Equivalents will be treated as separate payments from the underlying Units for purposes of Section 409A.

§ 7.    Unfunded Promise. The Performance Share Award constitutes a contingent and unsecured promise of the Company and Participant has only the rights of a general unsecured creditor of the Company, including, but not limited to, any rights in respect of settlement of the Performance Share Award.

§ 8.    Nontransferable. No rights under this Agreement shall be transferable by Participant, except as provided in Section 12 of the Plan.

§ 9.    Other Laws. The Company shall have the right to refuse to transfer shares of Stock subject to this Performance Share Award to Participant if the Company acting in its absolute discretion determines that the transfer of such shares is (in the opinion of the Company’s legal counsel) likely to violate any applicable law or regulation.

§ 10.    No Right to Continue Employment or Service. Neither the Plan , this Agreement, nor any related material shall give Participant the right to continue in the employment or other service of the Company or a Subsidiary or shall adversely affect the right which the Company or any Subsidiary has under applicable law to terminate Participant’s employment with or without cause at any time.

§ 11.    Clawback/Recoupment. Notwithstanding any other provision of this Agreement, the Performance Share Award shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) the Company's Clawback Policy and any other clawback, forfeiture or other similar policy adopted by the Board or the Committee and as in effect from time to time; and (ii) applicable law or stock exchange listing requirement. By accepting the Performance Share Award, Participant is deemed to have acknowledged and consented to the Company’s Clawback Policy and the Company's application, implementation and enforcement of any clawback, forfeiture or other similar policy adopted by the Board or the Committee, whether adopted prior to or following the date of the Award Date, and any provision of applicable law or stock exchange listing requirement relating to reduction cancellation, forfeiture or recoupment, and to have agreed that the Company may take such actions as may be necessary to effectuate any such policy, requirement or applicable law, without further consideration or action.

§ 12.    Governing Law. The Plan and this Agreement shall be governed by the laws of the State of Maryland, applied without regard to conflicts of law principles.

§ 13.    Binding Effect. This Agreement shall be binding upon the Company and Participant and their respective heirs, executors, administrators and successors.

§ 14.    Headings and Sections. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. All references to sections (§) in this Agreement shall be to sections (§) of this Agreement, unless reference to a section of the Plan is specifically made.

§ 15.    409A Compliance. The parties intend that payments under this Agreement comply with or be exempt from Section 409A and the Company shall have complete discretion to interpret and construe this Agreement and any associated documents in any manner that establishes an exemption from (or compliance with) the requirements of Section 409A. If for any reason, such as imprecision in drafting, any provision of this Agreement does not accurately reflect its intended establishment of an exemption from (or compliance with) Section 409A, as

demonstrated by consistent interpretations or other evidence of intent, such provision shall be considered ambiguous as to its exemption from (or compliance with) Section 409A and shall be interpreted by the Company in a manner consistent with such intent, as determined in the discretion of the Company. A termination of employment or other Termination of Service shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Section 409A upon or following a termination of employment or other Termination of Service unless such termination is also a “separation from service” within the meaning of Section 409A, and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment,” “Termination of Service” or like terms shall mean a “separation from service” from the Company. The determination of whether and when a separation from service has occurred for proposes of this Agreement shall be made in accordance with the presumptions set forth in Section 1.409A-1(h) of the Treasury Regulations. Any provision of this Agreement to the contrary notwithstanding, if at the time of Participant’s separation from service, the Company determines that Participant is a “specified employee,” within the meaning of Section 409A, then to the extent any payment that Participant is entitled to under this Agreement on account of Participant’s separation from service would be considered nonqualified deferred compensation under Section 409A, such payment shall be paid at the date which is the earlier of (i) six (6) months and one day after Participant’s separation from service and (ii) the date of Participant’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this § 15 shall be paid to Participant in a lump-sum. The Company makes no representation or warranty and shall have no liability to Participant or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A, but do not satisfy an exemption from, or the conditions of, Section 409A.

Participant has signed this Agreement to evidence Participant’s acceptance of this Performance Share Award and all of the terms and conditions of such Award.

(b)    “Board” shall mean the Board of Directors of the Company.

(c)    “Clawback Eligible Incentive Compensation” shall mean, in connection with an Accounting Restatement and with respect to each individual who served as an Executive Officer at any time during the applicable performance period for any Incentive-based Compensation (whether or not such Executive Officer is serving at the time the Erroneously Awarded Compensation is required to be repaid to the Company Group), all Incentive-based Compensation Received by such Executive Officer (i) on or after October 2, 2023, (ii) after beginning service as an Executive Officer, (iii) while the Company has a class of securities listed on a national securities exchange or a national securities association and (iv) during the applicable Clawback Period.

(j)    “Executive Officer” shall mean (i) the Company’s current and former president, principal financial officer, principal accounting officer (or if there is no principal accounting officer, the controller), any vice-president in charge of a principal business unit, division or function (such as sales, administration, or finance), any other officer who performs a policy-making function for the Company, or any other person who performs similar policy-making functions for the Company, as determined by the Committee in accordance with Federal securities laws, SEC rules or the rules of any national securities exchange or national securities association on which the Company’s securities are listed. Identification of an executive officer for purposes of this Policy includes at a minimum executive officers identified pursuant to 17 C.F.R. 229.401(b).

(k)    “Financial Reporting Measures” shall mean measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and all other measures that are derived wholly or in part from such measures. Stock price and total shareholder return (and any measures that are derived wholly or in part from stock price or total shareholder return) shall for purposes of this Policy be considered Financial Reporting Measures. For the avoidance of doubt, a Financial Reporting Measure need not be presented in the Company’s financial statements or included in a filing with the SEC.

(l)    “Incentive-based Compensation” shall mean any compensation that is granted, earned or vested based wholly or in part upon the attainment of a Financial Reporting Measure.

(n)    “Received” shall, with respect to any Incentive-based Compensation, mean actual or deemed receipt, and Incentive-based Compensation shall be deemed received in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive-based Compensation award is attained, even if payment or grant of the Incentive-based Compensation occurs after the end of that period.

(o)    “Restatement Date” shall mean the earlier to occur of (i) the date the Board, a committee of the Board or the officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the issuer is required to prepare an Accounting Restatement, or (ii) the date of court, regulator or other legally authorized body directs the issuer to prepare an Accounting Restatement.

(p)    “SEC” shall mean the U.S. Securities and Exchange Commission.

4.    Repayment of Erroneously Awarded Compensation.

(a)    In the event of an Accounting Restatement, the Committee shall determine the amount of any Erroneously Awarded Compensation for each Executive Officer in connection with such Accounting Restatement and thereafter, provide each Executive Officer with a written notice containing the amount of Erroneously Awarded Compensation and a demand for repayment or return, as applicable. For Incentive-based Compensation based on (or derived from) stock price or total shareholder return where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the applicable Accounting Restatement, the amount shall be determined by the Committee based on a reasonable estimate of the effect of the Accounting Restatement on the stock price or total shareholder return upon which the Incentive-based Compensation was Received (in which case, the Company shall maintain documentation of such determination of that reasonable estimate and provide such documentation to the NYSE).

(b)    The Committee shall take such action as it deems appropriate to recover Erroneously Awarded Compensation reasonably promptly after such obligation is incurred and shall have broad discretion to determine the appropriate means of recovery of such Erroneously Awarded Compensation based on all applicable facts and circumstances. The Committee may seek recoupment in the manner it chooses, in its sole discretion, which may include, without limitation, one or a combination of the following: (i) direct reimbursement from the Executive Officer of Incentive-based Compensation previously paid, (ii) deduction of the recouped amount from unpaid compensation otherwise owed by the Company to the Covered Executive, (iii) set-off, (iv) rescinding or cancelling vested or unvested equity or cash based awards, and (v) any other remedial and recovery action permitted by law, as determined by the Committee. For the avoidance of doubt, except as set forth in Section 4(d) below, in no event may the Company Group accept an amount that is less than the amount of Erroneously Awarded Compensation in satisfaction of an Executive Officer’s obligations hereunder.

(c)    To the extent that an Executive Officer fails to repay all Erroneously Awarded Compensation to the Company Group when due (as determined in accordance with Section 4(b) above), the Company shall, or shall cause one or more other members of the Company Group to, take all actions reasonable and appropriate to recover such Erroneously Awarded Compensation from the applicable Executive Officer. The applicable Executive Officer shall be required to reimburse the Company Group for any and all expenses reasonably incurred (including legal fees) by the Company Group in recovering such Erroneously Awarded Compensation in accordance with the immediately preceding sentence.

(d)    Notwithstanding anything herein to the contrary, the Company shall not be required to take the actions contemplated by Section 4(b) above if the following conditions are met and the Committee determines that recovery would be impracticable:

(i)    The direct expenses paid to a third party to assist in enforcing the Policy against an Executive Officer would exceed the amount to be recovered, after the Company has made a reasonable attempt to recover the applicable Erroneously Awarded Compensation, documented such attempts and provided such documentation to the NYSE.

(ii)    Recovery would violate home country law where that law was adopted prior to November 28, 2022, provided that, before determining that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on violation of home country law, the Company has obtained an opinion of home country counsel, acceptable to the NYSE, that recovery would result in such a violation and a copy of the opinion is provided to the NYSE;or

(iii)    Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company Group, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

5.    Reporting and Disclosure. The Company shall file all disclosures with respect to this Policy in accordance with the requirement of the Federal securities laws, including the disclosure required by the applicable SEC filings.

6.    Indemnification Prohibition. No member of the Company Group shall be permitted to indemnify any Executive Officer against (i) the loss of any Erroneously Awarded Compensation that is repaid, returned or recovered pursuant to the terms of this Policy, or (ii) any claims relating to the Company Group’s enforcement of its rights under this Policy. Further, no member of the Company Group shall enter into any agreement that exempts any Incentive-based Compensation from the application of this Policy or that waives the Company Group’s right to recovery of any Erroneously Awarded Compensation and this Policy shall supersede any such agreement (whether entered into before, on or after the Effective Date).

7.    Interpretation. The Committee is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate, or advisable for the administration of this Policy. This Policy shall be binding and enforceable against all Executive Officers and their beneficiaries, heirs, executors or other legal representatives.

8.    Effective Date. This Policy shall be effective as of the Effective Date.

9.    Amendment; Termination. The Committee may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary, including as and when it determines that it is legally required by any Federal securities laws, SEC rules or the rules of any national securities exchange or national securities association on which the Company’s securities are listed. The Committee may terminate this Policy at any time. Notwithstanding anything in this Section 9 to the contrary, no amendment or termination of this Policy shall be effective if such amendment or termination would (after taking into account any actions taken by the Company contemporaneously with such amendment or termination) cause the Company to violate any Federal securities laws, SEC rules or the rules of any national securities exchange or national securities association on which the Company’s securities are listed.

10.    Other Recoupment Rights; No Additional Payments. The Committee intends that this Policy will be applied to the fullest extent of the law. This Policy shall be incorporated by reference into and shall apply to all incentive, bonus, equity, equity-based and compensation plans, agreements, and awards outstanding as of the Effective Date or entered into on or after the Policy’s Effective Date. The Committee may require that any employment agreement, equity award agreement, or any other agreement entered into on or after the Effective Date shall, as a condition to the grant of any benefit thereunder, require an Executive Officer to agree to abide by the terms of this Policy. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment that may be available to the Company Group under applicable law, regulation or rule or pursuant to the terms of any similar policy in any employment agreement, equity award agreement, or similar agreement and any other legal remedies available to the Company Group.

11.    Entire Agreement. This Policy supersedes, replaces and merges any and all previous agreements and understandings regarding the Company’s policy on the recovery of compensation, and this Policy constitutes the entire agreement between the Company and the Executive Officers with respect to such terms and conditions.

12.    Successors. This Policy shall be binding and enforceable against all Executive Officers and their beneficiaries, heirs, executors, administrators or other legal representatives.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements of Piedmont are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Piedmont, Piedmont’s wholly-owned subsidiaries, any variable interest entity ("VIE") of which Piedmont or any of its wholly-owned subsidiaries is considered to have the power to direct the activities of the entity and the obligation to absorb losses/right to receive benefits, or any entity in which Piedmont or any of its wholly-owned subsidiaries owns a controlling interest. In determining whether Piedmont or Piedmont OP has a controlling interest, the following factors, among others, are considered: equity ownership, voting rights, protective rights of investors, and participatory rights of investors.

Piedmont owns a majority interest in four properties through three joint ventures. Two of these joint ventures, 1201 and 1225 Eye Street, NW Associates, own the 1201 and 1225 Eye Street buildings, respectively, in Washington, D.C. The other joint venture, Piedmont-CNL Towers Orlando, LLC, owns CNL Center I and II, in Orlando, Florida. All three joint venture investments are consolidated under the voting model. Accordingly, Piedmont’s consolidated financial statements include the accounts of 1201 Eye Street, NW Associates, LLC, 1225 Eye Street, NW Associates, LLC, and Piedmont-CNL Towers Orlando, LLC.

All inter-company balances and transactions have been eliminated upon consolidation.

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

Use of Estimates

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

Real Estate Assets

Piedmont classifies its real estate assets as long-lived assets held for use or as long-lived assets held for sale. Held for use assets are stated at cost, as adjusted for any impairment loss, less accumulated depreciation. Held for sale assets are carried at lower of depreciated cost or estimated fair value, less estimated costs to sell. Piedmont generally reclassifies assets as held for sale once a sales contract has been executed and earnest money has become non-refundable.

Amounts capitalized to real estate assets consist of the cost of acquisition or construction, any tenant improvements or major improvements, betterments that extend the useful life of the related asset, and transaction costs associated with the acquisition of an individual asset that does not qualify as a business combination. All repairs and maintenance are expensed as incurred. Additionally, Piedmont capitalizes interest and other costs such as taxes and insurance while the development, or redevelopment, of a real estate asset is in progress.

Piedmont’s real estate assets are depreciated or amortized using the straight-line method over the following useful lives:

Buildings	40 years
Building improvements	5-25 years
Land improvements	20-25 years
Tenant allowances	Lease term
Furniture, fixtures, and equipment	3-10 years
Intangible lease assets	Lease term

Piedmont continually monitors events and changes in circumstances that could indicate that the carrying amounts of the real estate and related intangible assets of operating properties in which Piedmont has an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, management assesses 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 values, 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, management adjusts such assets to the respective estimated fair values and recognizes an impairment loss. Estimated fair values are calculated based on the following information, depending upon availability, in order of preference: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of undiscounted cash flows, including estimated sales value (which is based on key assumptions such as estimated market rents, lease-up periods, estimated lease terms, and capitalization and discount rates) less estimated selling costs.

Fair Value of Assets and Liabilities of Acquired Properties

Upon the acquisition of real properties, Piedmont records the fair value of properties (plus any related acquisition costs) allocated based on relative fair value as tangible assets, consisting of land and building, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based on their estimated fair values. Piedmont's property acquisitions typically qualify as asset acquisitions under Accounting Standards Codification ("ASC") 805, Business Combinations.

The estimated fair values of the tangible assets of an acquired property are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and building based on management’s determination of the estimated fair value of these assets. Management relies on a sales comparison approach using closed land sales and listings in determining the land value, and determines the as-if-vacant estimated fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates the cost to execute similar leases including leasing commissions, legal, and other related costs.

The estimated fair values of above-market and below-market in-place leases are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of market rates for the corresponding in-place leases, measured over a period equal to the remaining terms of the leases, taking into consideration the probability of renewals for any

below-market leases. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental revenues over the remaining terms of the respective leases.

The estimated fair values of in-place leases include an estimate of the direct costs associated with obtaining the acquired or "in place" tenant, estimates of opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease. The amount capitalized as a direct cost associated with obtaining a tenant includes commissions, tenant improvements, and other direct costs and is estimated based on management’s consideration of current market costs to execute a similar lease. These direct lease origination costs are included in deferred lease costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These lease intangibles are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases.

Gross intangible assets and liabilities, inclusive of amounts classified as real estate assets held for sale, recorded as of December 31, 2023 and 2022, respectively, are as follows (in thousands):

	December 31, 2023		December 31, 2022

(1)Included as a component of Deferred Lease Costs in the accompanying consolidated balance sheets.

Cash and Cash Equivalents

Piedmont considers all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents include cash and short-term investments. The majority of Piedmont’s cash and cash equivalents are held at major commercial banks and at times may exceed the Federal Deposit Insurance Corporation limit of $250,000. Short-term investments consist of investments in money market accounts stated at cost, which approximates estimated fair value, and available-for-sale securities associated with Piedmont's non-qualified deferred compensation program carried at estimated fair value.

Tenant Receivables and Straight-line Rent Receivables

Tenant receivables are comprised of rental and reimbursement billings due from tenants, and straight-line rent receivables representing the cumulative amount of future adjustments necessary to present rental income on a straight-line basis. Piedmont evaluates the collectibility of its operating lease receivables on a tenant/lease-specific basis and recognizes changes in the collectibility assessment of its operating lease receivables as a reduction of rental and tenant reimbursement revenues.

Allowance for Doubtful Accounts

As detailed above, Piedmont records contra-revenue adjustments to reduce tenant and straight-line rent receivables to their net realizable value when collectibility is in question. During the year ended December 31, 2020 Piedmont also established an allowance for doubtful accounts due to the general uncertainty regarding collectibility of certain tenant receivables during the COVID-19 pandemic. The majority of this allowance was ultimately not used and was reversed during the two years ended December 31, 2023. A roll forward of the allowance for doubtful accounts for the years ended December 31, 2023, 2022, and 2021 is as follows:

	Balance at Beginning of Period		Additions/Reversals as Decrease/(Increase) to Revenue		Write-offs		Balance at End of Period
Year Ended December 31,
2023	$	1,000	$	(1,000)	$	—	$	—
2022	$	4,000	$	(3,000)	$	—	$	1,000
2021	$	4,553	$	35	$	(588)	$	4,000

Restricted Cash and Escrows

Restricted cash and escrows principally relate to the following types of items:

•escrow accounts held by lenders to pay future real estate taxes, insurance, debt service, and tenant improvements;

•net sales proceeds from property sales held by qualified intermediary for potential Section 1031 exchange;

•earnest money paid in connection with future acquisitions; and

•security and utility deposits paid by tenants per the terms of their respective leases.

Restricted cash and escrows are generally reclassified to other asset or liability accounts upon being used to purchase assets, satisfy obligations, or settle tenant obligations.

Prepaid Expenses and Other Assets

Prepaid expenses and other assets are primarily comprised of the following items:

•prepaid property taxes, insurance and operating costs;

•receivables which are unrelated to tenants, for example, insurance proceeds receivable from insurers related to casualty losses; and

•equipment, furniture and fixtures, and tenant improvements for Piedmont’s corporate office and property management office space, net of accumulated depreciation.

Prepaid expenses and other assets will be expensed as utilized or depreciated in the case of Piedmont's corporate assets. Balances without a future economic benefit are expensed as they are identified.

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 Piedmont's reporting units. (See Note 14 below for further detail). Piedmont tests the carrying value of the goodwill assigned to each of its reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate 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 its goodwill impairment assessment, Piedmont compares the estimated fair value of each of its reporting units to the reporting unit’s carrying value. If Piedmont concludes that the fair value of a reporting unit is less than its carrying value, then Piedmont 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. Piedmont also makes assumptions 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.

As a result of impairment assessments performed during the years ended December 31, 2023 and 2022 Piedmont determined that portions of its goodwill related to various reporting units were impaired, and recorded goodwill impairment charges in each period as further described in Note 6 below.

Interest Rate Derivatives

Piedmont has periodically entered into interest rate derivative agreements to hedge its exposure to changing interest rates. As of December 31, 2023 and 2022, all of Piedmont's interest rate derivatives were designated as effective cash flow hedges and carried on the balance sheet at estimated fair value. Piedmont reassesses the effectiveness of its derivatives designated as cash flow hedges on a regular basis to determine if they continue to be highly effective and if the forecasted transactions remain highly probable. Piedmont does not use derivatives for trading or speculative purposes.

The changes in estimated fair value of interest rate swap agreements designated as effective cash flow hedges are recorded in other comprehensive income (“OCI”), and subsequently reclassified to earnings when the hedged transactions occur. The estimated fair value of the interest rate derivative agreement is recorded as interest rate derivative asset or as interest rate derivative liability in the accompanying consolidated balance sheets. Amounts received or paid under interest rate derivative agreements are recorded as reductions or additions to interest expense in the consolidated statements of operations as incurred. Additionally, when Piedmont settles forward starting swap agreements, any gain or loss is recorded as accumulated other comprehensive income and is amortized to interest expense over the term of the respective notes on a straight line basis (which approximates the effective interest method). Further, Piedmont classifies cash flows from the settlement of hedging derivative instruments in the same category as the underlying exposure which is being hedged. Settlements resulting from the hedge of Piedmont's exposure to interest rate changes are classified as operating cash flows in the accompanying consolidated statements of cash flows.

Deferred Lease Costs

Deferred lease costs are comprised of costs and incentives incurred to acquire operating leases. In addition to direct costs, deferred lease costs also include intangible lease origination costs related to in-place leases acquired as part of a property acquisition.

Deferred lease costs are amortized on a straight-line basis over the terms of the related underlying leases in the accompanying consolidated statements of operations as follows:

•Approximately $56.1 million, $57.9 million, and $56.4 million of deferred lease costs are included in amortization expense for the years ended December 31, 2023, 2022, and 2021, respectively; and

•Approximately $4.4 million, $4.2 million, and $3.9 million, of deferred lease costs related to lease incentives granted to tenants are included as an offset to rental and tenant reimbursement revenue for the years ended December 31, 2023, 2022, and 2021, respectively.

Upon receipt of an early lease termination notice, Piedmont recognizes any unamortized deferred lease costs ratably over the revised remaining term of the lease after giving effect to the termination notice. If there is no remaining lease term and no other obligation to provide the tenant space in the property, then any unamortized tenant-specific costs are recognized immediately.

Debt

When mortgage debt is assumed upon the acquisition of real property, Piedmont adjusts the loan to relative fair value with a corresponding adjustment to building and other intangible assets assumed as part of the purchase. The fair value adjustment is amortized to interest expense over the term of the loan using the effective interest method. Amortization of such fair value adjustments was approximately $0, $0, and $0.3 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Piedmont records premiums and discounts on debt issuances as an increase/decrease to the principal amount of the loan in the accompanying consolidated balance sheets, and amortizes such premiums or discounts as a component of interest expense over the life of the underlying loan facility using the effective interest method. Piedmont recorded discount amortization of approximately $0.7 million, $0.6 million and $0.5 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Piedmont presents all debt issuance costs as an offset to the principal amount of debt in the accompanying consolidated balance sheets. Piedmont amortizes these costs to interest expense on a straight-line basis (which approximates the effective interest rate method) over the terms of the related financing arrangements. Piedmont recognized amortization of such costs for the years ended December 31, 2023, 2022, and 2021 of approximately $4.7 million, $2.8 million, and $2.7 million, respectively.

Deferred income

Deferred income is primarily comprised of the following items:

•prepaid rent from tenants;

•tenant reimbursements related to operating expense or property tax expenses which may be due to tenants as part of an annual operating expense reconciliation; and

•tenant improvement allowance overages or improvements funded by the tenant where Piedmont owns the underlying improvements.

Deferred income related to prepaid rents from tenants will be recognized as rental income in the period it is earned. Amounts related to operating expense reconciliations or property tax expense are relieved when the tenant's reconciliation is completed in accordance with the underlying lease, and payment is issued to the tenant. Tenant improvement allowance overages or improvements paid for by the tenant, where Piedmont owns all of the underlying improvements, are recorded as deferred income and amortized on a straight-line basis into rental and tenant reimbursement revenue over the term of the respective leases.

Shares-in-trust

To date, Piedmont has not issued any shares-in-trust; however, under Piedmont’s charter, it has authority to issue a total of 150,000,000 shares-in-trust, which would be issued only in the event that there is a purported transfer of, or other change in or affecting the ownership of, Piedmont’s capital stock that would result in a violation of the ownership limits that are included in Piedmont’s charter to protect its REIT status.

Preferred Stock

To date, Piedmont has not issued any shares of preferred stock; however, Piedmont is authorized to issue up to 100,000,000 shares of one or more classes or series of preferred stock. Piedmont’s board of directors may determine the relative rights, preferences, and privileges of any class or series of preferred stock that may be issued, and can be more beneficial than the rights, preferences, and privileges attributable to Piedmont’s common stock.

Common Stock

Under Piedmont’s charter, it has authority to issue a total of 750,000,000 shares of common stock with a par value of $0.01 per share. Each share of common stock is entitled to one vote and participates in distributions equally. Piedmont previously had a board-authorized stock repurchase program, which expired in February 2024, under which it repurchased its own shares from time to time in the open market, in accordance with applicable securities laws.

Equity Securities Issued At-The-Market

Under Piedmont's at-the-market stock offering program ("ATM program"), Piedmont may offer and sell shares of its common stock from time to time in “at-the-market” offerings with an aggregate gross sales price of up to $250 million. In connection with the ATM Program, Piedmont may, at its discretion, enter into forward equity sale agreements. The use of a forward equity sale agreement would allow Piedmont to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date, allowing Piedmont to better align such funding with its capital needs. Sales of shares of Piedmont’s common stock through its banking relationships, if any, will be made in amounts and at times to be determined by Piedmont from time to time, but Piedmont has no obligation to sell any of the shares in the offering and may suspend sales in connection with the offering at any time. Sales of Piedmont's common stock under forward equity sale agreements, if undertaken, meet the derivatives and hedging guidance scope exception to be accounted for as equity instruments based on the following assessments: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for Piedmont's own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to Piedmont's own stock.

Underwriting commissions and offering costs incurred in connection with all common equity offerings, including any potential issuances under Piedmont's ATM Program, are reflected as a reduction of additional paid-in capital.

Dividends

As a REIT, Piedmont is required by the Internal Revenue Code of 1986, as amended (the “Code”), to make distributions to stockholders each taxable year equal to at least 90% of its annual taxable income, computed without regard to the dividends-paid deduction and by excluding net capital gains attributable to stockholders (“REIT taxable income”).

Noncontrolling Interest

Noncontrolling interest is the equity interest of consolidated entities that is not owned by Piedmont. Noncontrolling interest is adjusted for the noncontrolling partners' share of contributions, distributions, and earnings (losses) in accordance with the respective partnership agreement. Earnings allocated to such noncontrolling partners are recorded as income applicable to noncontrolling interest in the accompanying consolidated statements of operations.

Revenue Recognition

Piedmont's revenues consist of the following:

Rental and tenant reimbursement income - consists of revenue from leases with Piedmont's tenants, as well as reimbursements for services prescribed by such leases. Piedmont evaluates contracts at commencement to determine if the contract contains a lease. If a contract is determined to contain a lease, the lease is evaluated to determine whether it is an operating, sales-type, or a direct financing lease. All of Piedmont's leases where Piedmont is the lessor are for the lessee's use of space in Piedmont's commercial office properties and are classified as operating leases.

In most lease arrangements, Piedmont finances improvements to leased space and is deemed the owner of the tenant improvements. The determination of who owns the improvements, whether payments to tenants constitute lease incentives or tenant improvements, and the timing of revenue recognition requires the exercise of significant judgment based on the facts and circumstances of the specific lease arrangement and is not based on any one factor. When evaluating whether Piedmont or its tenant owns the improvements, management considers a number of factors, including, among other things:

•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.

These tenant improvements are recorded as capital assets by Piedmont and depreciated, typically over the lease term. Payments made by tenants for tenant improvements owned by Piedmont are treated as deferred income and amortized into rental and tenant reimbursement revenue over the lease term.

The timing of rental revenue recognition is largely dependent on our conclusion as to whether Piedmont, or its tenant, is the owner of tenant improvements at the leased property. When Piedmont owns the tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as Piedmont's asset are substantially complete. In some instances, Piedmont may cede control of the leased space to the tenant to be responsible for tenant-owned improvements for the space. In such arrangements, payments made by Piedmont to its tenant are treated as lease incentives and amortized as a reduction to rental and tenant reimbursement revenue over the lease term, which typically begins once the tenant takes possession of the unimproved space.

Lease payments are typically comprised of both fixed base rental payments and separately billed variable lease payments for reimbursement of services performed by Piedmont for the tenant as prescribed by the lease. Fixed base rental payments, as well as any fixed portion of reimbursement income, are recognized on a straight-line basis over the lease term. Tenant reimbursements are recognized as revenue in the period that the related operating cost is incurred. Rents and tenant reimbursements collected in advance are recorded as deferred income in the accompanying consolidated balance sheets.

Property management fee revenue - consists of revenue earned by Piedmont related to operating and managing office properties owned by other third-parties. Such income is within the scope of ASC 606, Revenue from Contracts with Customers ("ASC 606"). Because property management services represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed), property management fee revenue is recognized over time. Any variable consideration transferred as part of these management agreements is recognized in the quarter that the underlying cash receipts are collected, consistent with the allocation objective of allocating the transaction price in an amount that depicts the amount of consideration to which Piedmont expects to be entitled in exchange for transferring the promised service to the customer.

Other property related income - consists of all other property related income from Piedmont's customers (tenants) that is not derived from a contract meeting the definition of a lease and is therefore also within the scope of ASC 606. Examples of such income include parking revenue and income from licenses with unrelated third-parties to place antennae and/or fiber optic cables in or on Piedmont's buildings. These services also represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed); therefore, revenue related to these licenses is also recognized over time.

Gains on the sale of real estate assets, like all non-lease related revenue, are subject to a five-step model requiring that Piedmont identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue upon satisfaction of the performance obligations. In circumstances where Piedmont contracts to sell a property with material post-sale involvement, such involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post-sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized as gain on sale of real estate assets. Property dispositions with no continuing involvement will continue to be recognized upon closing of the sale. In circumstances where Piedmont extends seller financing as part of a sale of real estate assets, Piedmont assesses the collectibility of the notes receivable as of each reporting period end. Notes receivable that are deemed to be uncollectible or fully in default are reduced to their net realizable value, which approximates their fair value.

Stock-based Compensation

Piedmont has issued stock-based compensation in the form of deferred stock units to its employees and board of directors. For employees, Piedmont's Long-term Incentive Compensation ("LTIC") program is comprised of an annual deferred stock unit component (the "Annual Deferred Stock Unit" program) and a multi-year performance share component (the "Performance Share" program). All awards granted during the three years ended December 31, 2023 pursuant to both the Annual Deferred Stock Unit and Performance Share programs, as well as director's awards, were classified as equity awards and expensed on a straight-line basis over the vesting period, with issuances recorded as a reduction to additional paid in capital. Forfeitures are recorded when they occur. Awards granted prior to the three-year service period (2020-2022) pursuant to the Performance Share component of the LTIC program were classified as liability awards and remeasured at fair value as of the end of each reporting period during the service period, with issuances recorded as a reduction to accrued expense. Compensation expense recognized related to both of these award types is recorded as property operating costs for those employees whose job is related to property operations and as general and administrative expense for all other employees and board of directors in the accompanying consolidated statements of operations.

Net Income/(Loss) Available to Common Stockholders Per Share

Net income/(loss) per share-basic is calculated as net income/(loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income/(loss) per share-diluted is calculated as net income/(loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including the dilutive effect of nonvested restricted stock. The dilutive effect of nonvested restricted stock is calculated using the treasury stock method to determine the number of additional common shares that would become outstanding if the remaining unvested restricted stock awards vested. Further, Piedmont has elected to use the "end of the reporting period" convention when using the treasury stock method to calculate the dilutive effect of any shares issued pursuant to forward equity sale agreements in connection with Piedmont's ATM Program described above. Under this methodology, the assumed sale proceeds are calculated using the closing price of Piedmont's stock as of the end of the respective reporting period.

Income Taxes

Piedmont has elected to be taxed as a REIT under the Code, and has operated as such, beginning with its taxable year ended December 31, 1998. To qualify as a REIT, Piedmont must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income. As a REIT, Piedmont is generally not subject to federal income taxes, subject to fulfilling, among other things, its taxable income distribution requirement. However, Piedmont is subject to federal income taxes related to the operations conducted by its taxable REIT subsidiary which have been provided for in the financial statements. These operations resulted in approximately $39,000, $10,000, and $379,000 in income tax recoveries for the years ended December 31, 2023, 2022, and 2021, respectively, as a component of other income/(expense) in the accompanying consolidated statements of operations. Further, Piedmont is subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in property operating costs in the accompanying consolidated financial statements.

Recent Accounting Pronouncements

Segment Expense Disclosure

The Financial Accounting Standards Board (the "FASB") has issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures ("ASU 2023-07). ASU 2023-07 requires expanded disclosure of significant segment expenses which are regularly provided to the chief operating decision maker ("CODM"); all entities that have a single reportable segment must provide existing segment disclosures; disclosure of the title and position of the CODM; and entities must disclose the amounts and a qualitative description of "other segment items", representing the difference between segment revenue less segment expenses reported in segment profit or loss. ASU 2023-07 is effective for Piedmont beginning with the Form 10-K for the year ended December 31, 2024, and subsequent interim periods thereafter. Piedmont is currently evaluating the potential impact of adoption; however, Piedmont does not anticipate any material impact to its consolidated financial statements as a result of adoption of ASU 2023-07.

Income Tax Disclosure

The FASB has issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures ("ASU 2023-09). ASU 2023-09 requires expanded disclosure of tax information, including a rate reconciliation and the amounts of

annual income taxes paid (net of refunds received), segregated by federal, state, and local jurisdictions.

Debt Disclosure [Abstract]

Debt

Debt

During the year ended December 31, 2023, Piedmont entered into a new, one-year, $215 million, floating-rate, unsecured term loan facility (the “$215 Million Unsecured 2023 Term Loan”) and issued $600 million in aggregate principal amount of 9.250% senior notes due July 20, 2028 (the “$600 Million Unsecured Senior Notes due 2028”).

The $600 Million Unsecured Senior Notes due 2028 are fully and unconditionally guaranteed by Piedmont. Interest is payable semi-annually on January 20 and July 20 of each year commencing January 20, 2024, and is subject to adjustment if Piedmont's corporate credit rating with either Moody’s Investors Services Inc. or S&P Global Ratings falls below investment grade (i.e. BBB-/Baa3). The $600 Million Unsecured Senior Notes due 2028 are subject to typical covenants that, subject to certain exceptions, include: (a) a limitation on the ability of Piedmont and Piedmont OP to, among other things, incur additional secured and unsecured indebtedness; (b) a limitation on the ability of Piedmont and Piedmont OP to merge, consolidate, sell, lease or otherwise dispose of their properties and assets substantially as an entirety; and (c) a requirement that Piedmont maintain a pool of unencumbered assets.

Also during the year ended December 31, 2023, Piedmont:

•fully repaid its $350 Million Unsecured Senior Notes that matured on June 1, 2023;

•redeemed and repaid (using proceeds from the $600 Million Unsecured Senior Notes due 2028) approximately $350 million of its $400 Million Senior Notes due 2024 through a tender offer, resulting in the recognition of an approximately $0.8 million of loss on early extinguishment of debt; and,

•repaid $100 million of the $200 Million Unsecured 2022 Term Loan Facility, scheduled to mature in December 2024.

On January 30, 2024, Piedmont:

•entered into a new, three-year, $200 Million unsecured syndicated bank term loan, due January 30, 2027 at Adjusted Daily Secured Overnight Financing Rate ("SOFR") plus 130 basis points;

•paid off the remaining $100 million of the $200 Million Unsecured 2022 Term Loan Facility;

•repaid $190 million of the $215 Million Unsecured 2023 Term Loan that was scheduled to mature on January 31, 2024; and,

•extended the remaining $25 million of the $215 Million Unsecured 2023 Term Loan to January 31, 2025.

As a result of the above refinancing activity, as of the date of this filing, Piedmont has approximately $325 million of unsecured debt with final maturities over the next three years.

Finally, during the year ended December 31, 2023, Piedmont amended its $250 million, floating-rate, unsecured term loan facility (the "$250 Million Unsecured 2018 Term Loan") to convert the reference interest rate from LIBOR to SOFR, along with the various other related amendments necessary to affect this conversion.

The following table summarizes the terms of Piedmont’s indebtedness outstanding as of December 31, 2023 and 2022, including net discounts/premiums and unamortized debt issuance costs (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

Risk Management Objective of Using Derivatives

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

Cash Flow Hedges of Interest Rate Risk

Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for Piedmont making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

As of December 31, 2023, Piedmont was party to a total of eight interest rate swap agreements which are designated as effective cash flow hedges and fully hedge the variable cash flows covering the entire outstanding balance of the $250 Million Unsecured 2018 Term Loan through the maturity of the loan in March 2025. The maximum length of time over which Piedmont is hedging its exposure to the variability in future cash flows related to these interest rate swap agreements is 15 months.

During the year ended December 31, 2021, Piedmont entered into, and subsequently settled, one forward starting interest rate swap agreement with a notional value of $50 million to hedge the risk of changes in the interest-related cash flows associated with the issuance of the $300 Million Unsecured Senior Notes due 2032 (see Note 3). The settlement resulted in a gain of approximately $0.6 million, which was recorded as accumulated OCI and is being amortized as an offset to interest expense over the following ten years.

A detail of Piedmont’s interest rate derivatives outstanding as of December 31, 2023 is as follows:

Interest Rate Derivatives:	Number of Swap Agreements	Associated Debt Instrument	Notional Amount (in millions)		Effective Date	Maturity Date
Interest rate swaps	2	$250 Million Unsecured 2018 Term Loan	$	100	3/29/2018	3/31/2025
Interest rate swaps	3	$250 Million Unsecured 2018 Term Loan	75		12/2/2022	3/31/2025
Interest rate swaps	3	$250 Million Unsecured 2018 Term Loan	$	75	12/12/2022	3/31/2025
Total			$	250

Piedmont presents its interest rate derivatives on its consolidated balance sheets on a gross basis as interest rate swap assets and interest rate swap liabilities. A detail of Piedmont’s interest rate derivatives on a gross and net basis as of December 31, 2023 and 2022, respectively, is as follows (in thousands):

Interest rate swaps classified as:	December 31, 2023		December 31, 2022
Gross derivative assets	$	3,032	$	4,183
Gross derivative liabilities	—		—
Net derivative assets	$	3,032	$	4,183

The gain/(loss) on Piedmont's interest rate derivatives, including previously settled forward starting interest rate swaps, that was recorded in OCI and the accompanying consolidated statements of operations as a component of interest expense for the years ended December 31, 2023, 2022, and 2021, respectively, was as follows (in thousands):

Interest Rate Swaps in Cash Flow Hedging Relationships:	2023		2022		2021
Amount of gain recognized in OCI	$	2,626	$	8,202	$	2,994
Amount of previously recorded gain/(loss) reclassified from OCI into Interest Expense	$	3,365	$	(1,273)	$	(2,952)
Total amount of Interest Expense presented in the consolidated statements of operations	$	(101,258)	$	(65,656)	$	(51,292)
Total amount of Loss on Early Extinguishment of Debt presented in the consolidated statements of operations	$	(820)	$	—	$	—

Piedmont estimates that approximately $1.3 million will be reclassified from OCI as a decrease in interest expense over the next twelve months. Piedmont did not recognize any hedge ineffectiveness on its cash flow hedges during the three years ended December 31, 2023.

See Note 5 for fair value disclosures of Piedmont's derivative instruments.

Credit-risk-related Contingent Features

Piedmont has agreements with its derivative counterparties that contain a provision whereby if Piedmont defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Piedmont could also be declared in default on its derivative obligations. If Piedmont were to breach any of the contractual provisions of the derivative contracts, it could be required to settle its liability obligations under the agreements at their termination value of the estimated fair values plus accrued interest. However, as of December 31, 2023, all of Piedmont's interest rate swap agreements are in an asset position. Additionally, Piedmont has rights of set-off under certain of its derivative agreements related to potential termination fees and amounts payable under the agreements, if a termination were to occur.

Fair Value Disclosures [Abstract]

Fair Value Measurements of Financial Instruments

Fair Value Measurements of Financial Instruments

Piedmont considers its cash and cash equivalents, tenant receivables, notes receivable, restricted cash and escrows, accounts payable and accrued expenses, interest rate swap agreements, and debt to meet the definition of financial instruments. The following table sets forth the carrying and estimated fair value for each of Piedmont’s financial instruments, as well as its level within the GAAP fair value hierarchy, as of December 31, 2023 and 2022, respectively (in thousands):

	December 31, 2023					December 31, 2022
Financial Instrument	Carrying Value		Estimated Fair Value		Level Within Fair Value Hierarchy	Carrying Value		Estimated Fair Value		Level Within Fair Value Hierarchy
Assets:
Cash and cash equivalents (1)	$	825	$	825	Level 1	$	16,536	$	16,536	Level 1
Tenant receivables, net (1)	$	7,915	$	7,915	Level 1	$	4,762	$	4,762	Level 1
Restricted cash and escrows (1)	$	3,381	$	3,381	Level 1	$	3,064	$	3,064	Level 1

Debt, net	$	2,054,596	$	1,953,447	Level 2	$	1,983,681	$	1,825,723	Level 2

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

Piedmont's debt was carried at book value as of December 31, 2023 and 2022; however, Piedmont's estimate of its fair value is disclosed in the table above. Piedmont uses widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of the debt facilities, including the period to maturity of each instrument, and uses observable market-based inputs for similar debt facilities which have transacted recently in the market. Therefore, the estimated fair values determined are considered to be based on significant other observable inputs (Level 2). Scaling adjustments are made to these inputs to make them applicable to the remaining life of Piedmont's outstanding debt. Piedmont has not changed its valuation technique for estimating the fair value of its debt.

Piedmont’s interest rate swap agreements presented above, and as further discussed in Note 4, are classified as “Interest rate swaps” in the accompanying consolidated balance sheets and were carried at estimated fair value as of December 31, 2023 and 2022. The valuation of these derivative instruments was determined using widely accepted valuation techniques including discounted cash flow analysis based on the contractual terms of the derivatives, including the period to maturity of each instrument, and uses observable market-based inputs, including interest rate curves and implied volatilities. Therefore, the estimated fair values determined are considered to be based on significant other observable inputs (Level 2). In addition, Piedmont considered both its own and the respective counterparties’ risk of nonperformance in determining the estimated fair value of its derivative financial instruments by estimating the current and potential future exposure under the derivative financial instruments as of the valuation date. The credit risk of Piedmont and its counterparties was factored into the calculation of the estimated fair value of the interest rate swaps; however, as of December 31, 2023 and 2022, this credit valuation adjustment did not comprise a material portion of the estimated fair value. Therefore, Piedmont believes that any unobservable inputs used to determine the estimated fair values of its derivative financial instruments are not significant to the fair value measurements in their entirety, and does not consider any of its derivatives to be Level 3 financial instruments.

Impairment Charges

Impairment Charges

Goodwill Impairment Charges

During the years ended December 31, 2023 and 2022, Piedmont considered the decline in its stock price to be an indicator of impairment and performed several interim impairment assessments of its goodwill balance. These assessments involved comparing the estimated fair value of each of its reporting units (see Note 14) to the reporting unit’s carrying value, inclusive of the goodwill balance allocated to the reporting unit. Estimation of the fair value of each reporting unit involved the projection of discounted future cash flows using certain assumptions that are subjective in nature, including assumptions regarding future market rental rates and the number of months it may take to re-lease a property subsequent to the expiration of current lease agreements, as well as future property operating expenses, among other factors.

Based on the interim impairment assessments performed during the years ended December 31, 2023 and 2022, Piedmont determined that the carrying values of its Boston, Minneapolis, New York, and Northern Virginia/Washington D.C. reporting units (inclusive of each segment's assigned goodwill balance) exceeded the estimated fair value of each respective reporting unit and recorded goodwill impairment charges of approximately $29.4 million and $16.0 million, respectively, in the accompanying consolidated statement of operations. As the carrying value (inclusive of the assigned goodwill balance) of the Boston, Minneapolis, and Northern Virginia/Washington D.C. reporting units exceeded the estimated fair value of each respective reporting unit by an amount greater than the goodwill balance assigned to each unit, the charges for the Boston, Minneapolis, and Northern Virginia/Washington D.C. reporting units were equal to the goodwill balance that had been assigned to each segment. As this was not the case for the New York segment, the charge related to the New York reporting unit, was calculated based on the amount by which the carrying amount of the New York segment (inclusive of the assigned goodwill balance) exceeded the fair value of the New York reporting unit.

The fair value measurements used in the evaluations described above are considered to be Level 3 valuations within the fair value hierarchy as defined by GAAP as the measurements involve projections of discounted future cash flows, which are derived from unobservable assumptions, the most subjective of which are capitalization rates and discount rates for each respective reporting unit. The ranges of discount rates and the capitalization rate used for each segment in the above analyses, at the respective time the analyses were performed, were as follows:

		Range of Discount Rates		Range of Capitalization Rates
Reporting Unit	Valuation Date	Low	High	Low	High
Boston	December 31, 2023	8.25%	9.75%	8.25%	9.00%
Minneapolis	September 30, 2023	8.50%	9.25%	8.50%	9.00%
New York	December 31, 2023	9.50%	9.50%	9.00%	9.00%
Northern Virginia/Washington D.C.	December 31, 2022	8.50%	9.50%	8.25%	9.25%

Impairment Losses on Real Estate Assets

Piedmont recorded the following impairment losses on real estate assets for the years ended December 31, 2023, 2022, and 2021 (in thousands):

	2023		2022		2021
9320 Excelsior Boulevard	$	—	$	10,000	$	—
Two Pierce Place	—		—		41,000
Total impairment loss on real estate assets	$	—	$	10,000	$	41,000

Management shortened the intended hold period for each of the above buildings and in doing so, determined that the carrying value would not be recovered from the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. As a result, Piedmont recognized a loss on impairment calculated as the difference between the carrying value of the asset and the estimated fair value less costs to sell. The estimated fair values were determined based on net contract prices with unrelated, third-party purchasers for each respective building. The fair value measurements used in the evaluation of the non-financial assets above are considered to be Level 1 valuations within the fair value hierarchy as defined by GAAP, as there are direct observations and transactions involving the assets by unrelated, third-party purchasers. The Two Pierce Place building was subsequently sold during the year ended December 31, 2022.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Commitments Under Existing Lease Agreements

As a recurring part of its business, Piedmont is typically required under its executed lease agreements to fund tenant improvements, leasing commissions, and building improvements. In addition, certain agreements contain provisions that require Piedmont to issue corporate or property guarantees to provide funding for capital improvements or other financial obligations. As of December 31, 2023, Piedmont had one individually significant unrecorded tenant allowance commitment greater than $10 million. These commitments will be capitalized as the related expenditures are incurred.

Contingencies Related to Tenant Audits/Disputes

Certain lease agreements include provisions that grant tenants the right to engage independent auditors to audit their annual operating expense reconciliations. Such audits may result in different interpretations of language in the lease agreements from that made by Piedmont, which could result in requests for refunds of previously recognized tenant reimbursement revenues, resulting in financial loss to Piedmont. There were no such reductions during the three years ended December 31, 2023.

Litigation

Piedmont is from time to time a party to legal proceedings, which arise in the ordinary course of its business. None of these ordinary course legal proceedings are reasonably likely to have a material adverse effect on results of operations or financial condition. Piedmont is not aware of any such legal proceedings contemplated by governmental authorities.

Share-Based Payment Arrangement [Abstract]

Stock Based Compensation

Stock Based Compensation

Annually, the Compensation Committee of Piedmont's Board of Directors has granted deferred stock award units to certain employees at its discretion. Employee awards typically vest ratably over three or four years. In addition, Piedmont's independent directors receive an annual grant of deferred stock award units for services rendered and such awards vest over a one year service period.

Certain management employees' long-term equity incentive program is split between these deferred stock award units described above and a multi-year performance share program whereby actual awards are contingent upon Piedmont's total stockholder return ("TSR") performance relative to the TSR of a peer group of office REITs. The target incentives for these employees, as well as the peer group to be used for comparative purposes, are predetermined by the board of directors, advised by an outside compensation consultant. The number of shares earned, if any, are determined at the end of the multi-year performance period (or upon termination) and vest immediately. In the event that a participant's employment is terminated prior to the end of the multi-year period, in certain circumstances the participant may be entitled to a pro-rated award based on Piedmont's TSR relative performance as of the termination date. The grant date fair value of the multi-year performance share awards is estimated using the Monte Carlo valuation method and is recognized ratably over the performance period.

A rollforward of Piedmont's equity based award activity for the year ended December 31, 2023 is as follows:

	Shares	Weighted-Average Grant Date Fair Value
Unvested and Potential Stock Awards as of December 31, 2022	729,424	$	19.21

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

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

Net income/(loss) per share-basic is calculated as net income/(loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income/(loss) per share-diluted is calculated as net income/(loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including unvested deferred stock awards. Diluted weighted average number of common shares reflects the potential dilution under the treasury stock method that would occur if the remaining unvested and potential stock awards vested and resulted in additional common shares outstanding. Unvested and potential stock awards which are determined to be anti-dilutive are not included in the calculation of diluted weighted average common shares. For each of the years ended December 31, 2023, 2022, and 2021, Piedmont calculated and excluded weighted average outstanding anti-dilutive shares of approximately 1,030,824, 421,005, and 1,114,025, respectively.

Leases [Abstract]

Operating Leases

Operating Leases

Piedmont’s real estate assets are leased to tenants under operating leases for which the terms vary, including certain provisions to extend the lease term, options for early terminations subject to specified penalties, and other terms and conditions as negotiated. Piedmont retains substantially all of the risks and benefits of ownership of the real estate assets leased to tenants. Amounts required as security deposits vary depending upon the terms of the respective leases and the creditworthiness of the tenant; however, generally they are not significant. Exposure to credit risk exists to the extent that tenant receivables exceed this amount. Security deposits liabilities related to tenant leases are included in accounts payable, accrued expenses, and accrued capital expenditures in the accompanying consolidated balance sheets.

The future minimum rental income from Piedmont’s investment in real estate assets under non-cancelable operating leases as of December 31, 2023 is presented below (in thousands):

Years ending December 31:
2024	$	424,131

2027	322,114
2028	275,559
Thereafter	1,079,279
Total	$	2,865,316

Piedmont recognized the following fixed and variable lease payments, which together comprised rental and tenant reimbursement revenue in the accompanying consolidated statements of operations for the years ended December 31, 2023, 2022, and 2021, respectively, as follows (in thousands):

	2023		2022		2021

Total Rental and Tenant Reimbursement Revenue	$	555,313	$	545,741	$	514,619

Operating leases where Piedmont is the lessee relate primarily to office space in buildings owned by third parties and managed by Piedmont. Piedmont's right to use asset and corresponding lease liability, using Piedmont's incremental borrowing rate as the lease discount rate, was approximately $0.1 million for the year ended December 31, 2023 and approximately $0.2 million for the year ended December 31, 2022. For the three years ended December 31, 2023, Piedmont recognized approximately $0.1 million of operating lease costs, respectively. As of December 31, 2023, the lease term of Piedmont's right of use asset is one year, and the discount rate is 3.86%.

Segment Reporting [Abstract]

Segment Information

Segment Information

Piedmont's President and Chief Executive Officer has been identified as Piedmont's chief operating decision maker ("CODM"), as defined by GAAP. The CODM evaluates Piedmont's portfolio and assesses the ongoing operations and performance of its properties utilizing the following geographic segments: Atlanta, Dallas, Orlando, Northern Virginia/Washington, D.C., Minneapolis, New York, and Boston. These operating segments are also Piedmont’s reportable segments. As of December 31, 2023, Piedmont also owned two properties in Houston that do not meet the definition of an operating or reportable segment as the CODM does not regularly review these properties for purposes of allocating resources or assessing performance. Further, Piedmont does not maintain a significant presence or anticipate further investment in this market. These two properties are the primary contributors to accrual-based net operating income ("NOI") included in "Other" below. During the periods presented, there have been no material inter-segment transactions. The accounting policies of the reportable segments are the same as Piedmont's accounting policies.

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

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

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

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation and Principles of Consolidation

The consolidated financial statements of Piedmont are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Piedmont, Piedmont’s wholly-owned subsidiaries, any variable interest entity ("VIE") of which Piedmont or any of its wholly-owned subsidiaries is considered to have the power to direct the activities of the entity and the obligation to absorb losses/right to receive benefits, or any entity in which Piedmont or any of its wholly-owned subsidiaries owns a controlling interest. In determining whether Piedmont or Piedmont OP has a controlling interest, the following factors, among others, are considered: equity ownership, voting rights, protective rights of investors, and participatory rights of investors.

Principles of Consolidation

All inter-company balances and transactions have been eliminated upon consolidation.

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

Use of Estimates

Use of Estimates

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

Real Estate Assets

Real Estate Assets

Piedmont classifies its real estate assets as long-lived assets held for use or as long-lived assets held for sale. Held for use assets are stated at cost, as adjusted for any impairment loss, less accumulated depreciation. Held for sale assets are carried at lower of depreciated cost or estimated fair value, less estimated costs to sell. Piedmont generally reclassifies assets as held for sale once a sales contract has been executed and earnest money has become non-refundable.

Amounts capitalized to real estate assets consist of the cost of acquisition or construction, any tenant improvements or major improvements, betterments that extend the useful life of the related asset, and transaction costs associated with the acquisition of an individual asset that does not qualify as a business combination. All repairs and maintenance are expensed as incurred. Additionally, Piedmont capitalizes interest and other costs such as taxes and insurance while the development, or redevelopment, of a real estate asset is in progress.

Piedmont’s real estate assets are depreciated or amortized using the straight-line method over the following useful lives:

Buildings	40 years
Building improvements	5-25 years
Land improvements	20-25 years
Tenant allowances	Lease term
Furniture, fixtures, and equipment	3-10 years
Intangible lease assets	Lease term

Piedmont continually monitors events and changes in circumstances that could indicate that the carrying amounts of the real estate and related intangible assets of operating properties in which Piedmont has an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present, management assesses 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 values, 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, management adjusts such assets to the respective estimated fair values and recognizes an impairment loss. Estimated fair values are calculated based on the following information, depending upon availability, in order of preference: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of undiscounted cash flows, including estimated sales value (which is based on key assumptions such as estimated market rents, lease-up periods, estimated lease terms, and capitalization and discount rates) less estimated selling costs.

Fair Value of Assets and Liabilities of Acquired Properties

Fair Value of Assets and Liabilities of Acquired Properties

Upon the acquisition of real properties, Piedmont records the fair value of properties (plus any related acquisition costs) allocated based on relative fair value as tangible assets, consisting of land and building, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based on their estimated fair values. Piedmont's property acquisitions typically qualify as asset acquisitions under Accounting Standards Codification ("ASC") 805, Business Combinations.

The estimated fair values of the tangible assets of an acquired property are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and building based on management’s determination of the estimated fair value of these assets. Management relies on a sales comparison approach using closed land sales and listings in determining the land value, and determines the as-if-vacant estimated fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates the cost to execute similar leases including leasing commissions, legal, and other related costs.

The estimated fair values of above-market and below-market in-place leases are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of market rates for the corresponding in-place leases, measured over a period equal to the remaining terms of the leases, taking into consideration the probability of renewals for any

below-market leases. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental revenues over the remaining terms of the respective leases.

The estimated fair values of in-place leases include an estimate of the direct costs associated with obtaining the acquired or "in place" tenant, estimates of opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease. The amount capitalized as a direct cost associated with obtaining a tenant includes commissions, tenant improvements, and other direct costs and is estimated based on management’s consideration of current market costs to execute a similar lease. These direct lease origination costs are included in deferred lease costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These lease intangibles are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases.

Cash and Cash Equivalents

Cash and Cash Equivalents

Piedmont considers all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents include cash and short-term investments. The majority of Piedmont’s cash and cash equivalents are held at major commercial banks and at times may exceed the Federal Deposit Insurance Corporation limit of $250,000. Short-term investments consist of investments in money market accounts stated at cost, which approximates estimated fair value, and available-for-sale securities associated with Piedmont's non-qualified deferred compensation program carried at estimated fair value.

Tenant Receivables and Straight-line Rent Receivables

Tenant Receivables and Straight-line Rent Receivables

Tenant receivables are comprised of rental and reimbursement billings due from tenants, and straight-line rent receivables representing the cumulative amount of future adjustments necessary to present rental income on a straight-line basis. Piedmont evaluates the collectibility of its operating lease receivables on a tenant/lease-specific basis and recognizes changes in the collectibility assessment of its operating lease receivables as a reduction of rental and tenant reimbursement revenues.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

As detailed above, Piedmont records contra-revenue adjustments to reduce tenant and straight-line rent receivables to their net realizable value when collectibility is in question. During the year ended December 31, 2020 Piedmont also established an allowance for doubtful accounts due to the general uncertainty regarding collectibility of certain tenant receivables during the COVID-19 pandemic. The majority of this allowance was ultimately not used and was reversed during the two years ended December 31, 2023.

Restricted Cash and Escrows

Restricted Cash and Escrows

Restricted cash and escrows principally relate to the following types of items:

•escrow accounts held by lenders to pay future real estate taxes, insurance, debt service, and tenant improvements;

•net sales proceeds from property sales held by qualified intermediary for potential Section 1031 exchange;

•earnest money paid in connection with future acquisitions; and

•security and utility deposits paid by tenants per the terms of their respective leases.

Restricted cash and escrows are generally reclassified to other asset or liability accounts upon being used to purchase assets, satisfy obligations, or settle tenant obligations.

Prepaid Expenses and Other Assets

Prepaid Expenses and Other Assets

Prepaid expenses and other assets are primarily comprised of the following items:

•prepaid property taxes, insurance and operating costs;

•receivables which are unrelated to tenants, for example, insurance proceeds receivable from insurers related to casualty losses; and

•equipment, furniture and fixtures, and tenant improvements for Piedmont’s corporate office and property management office space, net of accumulated depreciation.

Prepaid expenses and other assets will be expensed as utilized or depreciated in the case of Piedmont's corporate assets. Balances without a future economic benefit are expensed as they are identified.

Goodwill

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 Piedmont's reporting units. (See Note 14 below for further detail). Piedmont tests the carrying value of the goodwill assigned to each of its reporting units for impairment on an annual basis, or on an interim basis if an event occurs or circumstances change that would indicate 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 its goodwill impairment assessment, Piedmont compares the estimated fair value of each of its reporting units to the reporting unit’s carrying value. If Piedmont concludes that the fair value of a reporting unit is less than its carrying value, then Piedmont 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. Piedmont also makes assumptions 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.

As a result of impairment assessments performed during the years ended December 31, 2023 and 2022 Piedmont determined that portions of its goodwill related to various reporting units were impaired, and recorded goodwill impairment charges in each period as further described in Note 6 below.

Interest Rate Derivatives and Risk Management Objective of Using Derivatives

Interest Rate Derivatives

Piedmont has periodically entered into interest rate derivative agreements to hedge its exposure to changing interest rates. As of December 31, 2023 and 2022, all of Piedmont's interest rate derivatives were designated as effective cash flow hedges and carried on the balance sheet at estimated fair value. Piedmont reassesses the effectiveness of its derivatives designated as cash flow hedges on a regular basis to determine if they continue to be highly effective and if the forecasted transactions remain highly probable. Piedmont does not use derivatives for trading or speculative purposes.

The changes in estimated fair value of interest rate swap agreements designated as effective cash flow hedges are recorded in other comprehensive income (“OCI”), and subsequently reclassified to earnings when the hedged transactions occur. The estimated fair value of the interest rate derivative agreement is recorded as interest rate derivative asset or as interest rate derivative liability in the accompanying consolidated balance sheets. Amounts received or paid under interest rate derivative agreements are recorded as reductions or additions to interest expense in the consolidated statements of operations as incurred. Additionally, when Piedmont settles forward starting swap agreements, any gain or loss is recorded as accumulated other comprehensive income and is amortized to interest expense over the term of the respective notes on a straight line basis (which approximates the effective interest method). Further, Piedmont classifies cash flows from the settlement of hedging derivative instruments in the same category as the underlying exposure which is being hedged. Settlements resulting from the hedge of Piedmont's exposure to interest rate changes are classified as operating cash flows in the accompanying consolidated statements of cash flows.

Risk Management Objective of Using Derivatives

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

Deferred Lease Costs

Deferred Lease Costs

Deferred lease costs are comprised of costs and incentives incurred to acquire operating leases. In addition to direct costs, deferred lease costs also include intangible lease origination costs related to in-place leases acquired as part of a property acquisition.

Deferred lease costs are amortized on a straight-line basis over the terms of the related underlying leases in the accompanying consolidated statements of operations as follows:

•Approximately $56.1 million, $57.9 million, and $56.4 million of deferred lease costs are included in amortization expense for the years ended December 31, 2023, 2022, and 2021, respectively; and

•Approximately $4.4 million, $4.2 million, and $3.9 million, of deferred lease costs related to lease incentives granted to tenants are included as an offset to rental and tenant reimbursement revenue for the years ended December 31, 2023, 2022, and 2021, respectively.

Upon receipt of an early lease termination notice, Piedmont recognizes any unamortized deferred lease costs ratably over the revised remaining term of the lease after giving effect to the termination notice. If there is no remaining lease term and no other obligation to provide the tenant space in the property, then any unamortized tenant-specific costs are recognized immediately.

Debt

Debt

When mortgage debt is assumed upon the acquisition of real property, Piedmont adjusts the loan to relative fair value with a corresponding adjustment to building and other intangible assets assumed as part of the purchase. The fair value adjustment is amortized to interest expense over the term of the loan using the effective interest method.Piedmont records premiums and discounts on debt issuances as an increase/decrease to the principal amount of the loan in the accompanying consolidated balance sheets, and amortizes such premiums or discounts as a component of interest expense over the life of the underlying loan facility using the effective interest method.Piedmont presents all debt issuance costs as an offset to the principal amount of debt in the accompanying consolidated balance sheets. Piedmont amortizes these costs to interest expense on a straight-line basis (which approximates the effective interest rate method) over the terms of the related financing arrangements.

Deferred income and Revenue Recognition

Deferred income

Deferred income is primarily comprised of the following items:

•prepaid rent from tenants;

•tenant reimbursements related to operating expense or property tax expenses which may be due to tenants as part of an annual operating expense reconciliation; and

•tenant improvement allowance overages or improvements funded by the tenant where Piedmont owns the underlying improvements.

Deferred income related to prepaid rents from tenants will be recognized as rental income in the period it is earned. Amounts related to operating expense reconciliations or property tax expense are relieved when the tenant's reconciliation is completed in accordance with the underlying lease, and payment is issued to the tenant. Tenant improvement allowance overages or improvements paid for by the tenant, where Piedmont owns all of the underlying improvements, are recorded as deferred income and amortized on a straight-line basis into rental and tenant reimbursement revenue over the term of the respective leases.

Revenue Recognition

Piedmont's revenues consist of the following:

Rental and tenant reimbursement income - consists of revenue from leases with Piedmont's tenants, as well as reimbursements for services prescribed by such leases. Piedmont evaluates contracts at commencement to determine if the contract contains a lease. If a contract is determined to contain a lease, the lease is evaluated to determine whether it is an operating, sales-type, or a direct financing lease. All of Piedmont's leases where Piedmont is the lessor are for the lessee's use of space in Piedmont's commercial office properties and are classified as operating leases.

In most lease arrangements, Piedmont finances improvements to leased space and is deemed the owner of the tenant improvements. The determination of who owns the improvements, whether payments to tenants constitute lease incentives or tenant improvements, and the timing of revenue recognition requires the exercise of significant judgment based on the facts and circumstances of the specific lease arrangement and is not based on any one factor. When evaluating whether Piedmont or its tenant owns the improvements, management considers a number of factors, including, among other things:

•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.

These tenant improvements are recorded as capital assets by Piedmont and depreciated, typically over the lease term. Payments made by tenants for tenant improvements owned by Piedmont are treated as deferred income and amortized into rental and tenant reimbursement revenue over the lease term.

The timing of rental revenue recognition is largely dependent on our conclusion as to whether Piedmont, or its tenant, is the owner of tenant improvements at the leased property. When Piedmont owns the tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the finished space, which is typically when the improvements being recorded as Piedmont's asset are substantially complete. In some instances, Piedmont may cede control of the leased space to the tenant to be responsible for tenant-owned improvements for the space. In such arrangements, payments made by Piedmont to its tenant are treated as lease incentives and amortized as a reduction to rental and tenant reimbursement revenue over the lease term, which typically begins once the tenant takes possession of the unimproved space.

Lease payments are typically comprised of both fixed base rental payments and separately billed variable lease payments for reimbursement of services performed by Piedmont for the tenant as prescribed by the lease. Fixed base rental payments, as well as any fixed portion of reimbursement income, are recognized on a straight-line basis over the lease term. Tenant reimbursements are recognized as revenue in the period that the related operating cost is incurred. Rents and tenant reimbursements collected in advance are recorded as deferred income in the accompanying consolidated balance sheets.

Property management fee revenue - consists of revenue earned by Piedmont related to operating and managing office properties owned by other third-parties. Such income is within the scope of ASC 606, Revenue from Contracts with Customers ("ASC 606"). Because property management services represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed), property management fee revenue is recognized over time. Any variable consideration transferred as part of these management agreements is recognized in the quarter that the underlying cash receipts are collected, consistent with the allocation objective of allocating the transaction price in an amount that depicts the amount of consideration to which Piedmont expects to be entitled in exchange for transferring the promised service to the customer.

Other property related income - consists of all other property related income from Piedmont's customers (tenants) that is not derived from a contract meeting the definition of a lease and is therefore also within the scope of ASC 606. Examples of such income include parking revenue and income from licenses with unrelated third-parties to place antennae and/or fiber optic cables in or on Piedmont's buildings. These services also represent a performance obligation that is satisfied over the length of the contract, not at any specific point in time, and has the same measure of transfer (time elapsed); therefore, revenue related to these licenses is also recognized over time.

Gains on the sale of real estate assets, like all non-lease related revenue, are subject to a five-step model requiring that Piedmont identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue upon satisfaction of the performance obligations. In circumstances where Piedmont contracts to sell a property with material post-sale involvement, such involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post-sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized as gain on sale of real estate assets. Property dispositions with no continuing involvement will continue to be recognized upon closing of the sale. In circumstances where Piedmont extends seller financing as part of a sale of real estate assets, Piedmont assesses the collectibility of the notes receivable as of each reporting period end. Notes receivable that are deemed to be uncollectible or fully in default are reduced to their net realizable value, which approximates their fair value.

Shares-in-trust, Preferred Stock, Common Stock, Equity Securities Issued At-The-Market, Dividends

Shares-in-trust

To date, Piedmont has not issued any shares-in-trust; however, under Piedmont’s charter, it has authority to issue a total of 150,000,000 shares-in-trust, which would be issued only in the event that there is a purported transfer of, or other change in or affecting the ownership of, Piedmont’s capital stock that would result in a violation of the ownership limits that are included in Piedmont’s charter to protect its REIT status.

Preferred Stock

To date, Piedmont has not issued any shares of preferred stock; however, Piedmont is authorized to issue up to 100,000,000 shares of one or more classes or series of preferred stock. Piedmont’s board of directors may determine the relative rights, preferences, and privileges of any class or series of preferred stock that may be issued, and can be more beneficial than the rights, preferences, and privileges attributable to Piedmont’s common stock.

Common Stock

Under Piedmont’s charter, it has authority to issue a total of 750,000,000 shares of common stock with a par value of $0.01 per share. Each share of common stock is entitled to one vote and participates in distributions equally. Piedmont previously had a board-authorized stock repurchase program, which expired in February 2024, under which it repurchased its own shares from time to time in the open market, in accordance with applicable securities laws.

Equity Securities Issued At-The-Market

Under Piedmont's at-the-market stock offering program ("ATM program"), Piedmont may offer and sell shares of its common stock from time to time in “at-the-market” offerings with an aggregate gross sales price of up to $250 million. In connection with the ATM Program, Piedmont may, at its discretion, enter into forward equity sale agreements. The use of a forward equity sale agreement would allow Piedmont to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date, allowing Piedmont to better align such funding with its capital needs. Sales of shares of Piedmont’s common stock through its banking relationships, if any, will be made in amounts and at times to be determined by Piedmont from time to time, but Piedmont has no obligation to sell any of the shares in the offering and may suspend sales in connection with the offering at any time. Sales of Piedmont's common stock under forward equity sale agreements, if undertaken, meet the derivatives and hedging guidance scope exception to be accounted for as equity instruments based on the following assessments: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for Piedmont's own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to Piedmont's own stock.

Underwriting commissions and offering costs incurred in connection with all common equity offerings, including any potential issuances under Piedmont's ATM Program, are reflected as a reduction of additional paid-in capital.

Dividends

As a REIT, Piedmont is required by the Internal Revenue Code of 1986, as amended (the “Code”), to make distributions to stockholders each taxable year equal to at least 90% of its annual taxable income, computed without regard to the dividends-paid deduction and by excluding net capital gains attributable to stockholders (“REIT taxable income”).

Noncontrolling Interest

Noncontrolling Interest

Noncontrolling interest is the equity interest of consolidated entities that is not owned by Piedmont. Noncontrolling interest is adjusted for the noncontrolling partners' share of contributions, distributions, and earnings (losses) in accordance with the respective partnership agreement. Earnings allocated to such noncontrolling partners are recorded as income applicable to noncontrolling interest in the accompanying consolidated statements of operations.

Stock-based Compensation

Stock-based Compensation

Piedmont has issued stock-based compensation in the form of deferred stock units to its employees and board of directors. For employees, Piedmont's Long-term Incentive Compensation ("LTIC") program is comprised of an annual deferred stock unit component (the "Annual Deferred Stock Unit" program) and a multi-year performance share component (the "Performance Share" program). All awards granted during the three years ended December 31, 2023 pursuant to both the Annual Deferred Stock Unit and Performance Share programs, as well as director's awards, were classified as equity awards and expensed on a straight-line basis over the vesting period, with issuances recorded as a reduction to additional paid in capital. Forfeitures are recorded when they occur. Awards granted prior to the three-year service period (2020-2022) pursuant to the Performance Share component of the LTIC program were classified as liability awards and remeasured at fair value as of the end of each reporting period during the service period, with issuances recorded as a reduction to accrued expense. Compensation expense recognized related to both of these award types is recorded as property operating costs for those employees whose job is related to property operations and as general and administrative expense for all other employees and board of directors in the accompanying consolidated statements of operations.

Net Income/(Loss) Available to Common Stockholders Per Share

Net Income/(Loss) Available to Common Stockholders Per Share

Net income/(loss) per share-basic is calculated as net income/(loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period. Net income/(loss) per share-diluted is calculated as net income/(loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, including the dilutive effect of nonvested restricted stock. The dilutive effect of nonvested restricted stock is calculated using the treasury stock method to determine the number of additional common shares that would become outstanding if the remaining unvested restricted stock awards vested. Further, Piedmont has elected to use the "end of the reporting period" convention when using the treasury stock method to calculate the dilutive effect of any shares issued pursuant to forward equity sale agreements in connection with Piedmont's ATM Program described above. Under this methodology, the assumed sale proceeds are calculated using the closing price of Piedmont's stock as of the end of the respective reporting period.

Income Taxes

Income Taxes

Piedmont has elected to be taxed as a REIT under the Code, and has operated as such, beginning with its taxable year ended December 31, 1998. To qualify as a REIT, Piedmont must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income. As a REIT, Piedmont is generally not subject to federal income taxes, subject to fulfilling, among other things, its taxable income distribution requirement. However, Piedmont is subject to federal income taxes related to the operations conducted by its taxable REIT subsidiary which have been provided for in the financial statements. These operations resulted in approximately $39,000, $10,000, and $379,000 in income tax recoveries for the years ended December 31, 2023, 2022, and 2021, respectively, as a component of other income/(expense) in the accompanying consolidated statements of operations. Further, Piedmont is subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in property operating costs in the accompanying consolidated financial statements.
