PART I

Item 1. Business

OUR COMPANY

General. Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company”, “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”). We own, manage, lease, develop and selectively acquire office and data center properties. The majority of our portfolio is in locations that support the United States Government (“USG”) and its contractors, most of whom are engaged in national security, defense and information technology (“IT”) related activities servicing what we believe are growing, durable, priority missions (“Defense/IT Locations”). We also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (“Regional Office”). As of December 31, 2021, our properties included the following:

•186 properties totaling 21.7 million square feet comprised of 17.0 million square feet in 160 office properties and 4.7 million square feet in 26 single-tenant data center shells. We owned 19 of these data center shells through unconsolidated real estate joint ventures;

•11 properties under development (eight office properties and three data center shells), including one partially-operational property, that we estimate will total approximately 1.7 million square feet upon completion;

•approximately 720 acres of land controlled for future development that we believe could be developed into approximately 8.9 million square feet and 43 acres of other land; and

•a wholesale data center with a capacity of 19.25 megawatts that we sold on January 25, 2022.

We conduct almost all of our operations and own almost all of our assets through our operating partnership, Corporate Office Properties, L.P. (“COPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which COPT is the sole general partner. COPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”). In addition to owning real estate, COPLP also owns subsidiaries that provide real estate services such as property management, development and construction services primarily for our properties but also for third parties. Some of these services are performed by a taxable REIT subsidiary (“TRS”).

Equity interests in COPLP are in the form of common and preferred units. As of December 31, 2021, COPT owned 98.3% of the outstanding COPLP common units (“common units”) and there were no preferred units outstanding. Common units not owned by COPT carry certain redemption rights. The number of common units owned by COPT is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of COPT, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as that of COPT common shareholders.

COPT’s common shares are publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “OFC”.

We believe that COPT is organized and has operated in a manner that satisfies the requirements for taxation as a REIT under the Internal Revenue Code of 1986, as amended, and we intend to continue to operate COPT in such a manner. If COPT continues to qualify for taxation as a REIT, it generally will not be subject to Federal income tax on its taxable income (other than that of its TRS entities) that is distributed to its shareholders. A REIT is subject to a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its annual taxable income to its shareholders.

Our executive offices are located at 6711 Columbia Gateway Drive, Suite 300, Columbia, Maryland 21046 and our telephone number is (443) 285-5400.

Our Internet address is www.copt.com. We make available on our Internet website free of charge our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as soon as reasonably possible after we file such material with the Securities and Exchange Commission (the “SEC”). In addition, we have made available on our Internet website under the heading “Corporate Governance” the charters for our Board of Trustees’ Audit, Nominating and Corporate Governance, Compensation and Investment Committees, as well as our Corporate Governance Guidelines, Code of Business Conduct and Ethics and Code of Ethics for Financial Officers. We intend to make available on our website any future amendments or waivers to our Code of Business Conduct and Ethics and Code of Ethics for Financial Officers within four business days after any such amendments or waivers. The information on our Internet site is not part of this report.

The SEC maintains an Internet website that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC. This Internet website can be accessed at www.sec.gov.

Business and Growth Strategies

Our primary goal is to deliver attractive total returns to our shareholders. This section sets forth key components of our business and growth strategies that we have in place to support this goal.

Defense/IT Locations Strategy: We specialize in serving the unique requirements of tenants in our Defense/IT Locations properties. These properties are primarily occupied by the USG and contractor tenants engaged in what we believe are high priority security, defense and IT missions. These tenants’ missions pertain more to knowledge- and technology-based activities (i.e., cyber security, research and development and other highly-technical defense and security areas) than to force structure (i.e., troops) and weapon system mass production. Our office and data center shell portfolio is significantly concentrated in Defense/IT Locations, which as of December 31, 2021 accounted for 176 of the portfolio’s 186 properties, representing 87.5% of its annualized rental revenue, and we control developable land to accommodate future growth in these locations. These properties generally have higher tenant renewal rates than is typical in commercial office space due in large part to: their proximity to defense installations or other key demand drivers; the ability of many of these properties to meet Anti-Terrorism Force Protection (“ATFP”) requirements; and significant investments often made by tenants for unique needs such as Sensitive Compartmented Information Facility (“SCIF”), critical power supply and operational redundancy.

In recent years, data center shells have been a growth driver for our Defense/IT Locations. Data center shells are properties leased to tenants to be operated as data centers in which we provide tenants with only the core building and basic power, while the tenants fund the costs for the critical power, fiber connectivity and data center infrastructure. From 2013 through 2021, we placed into service 26 data center shells totaling 4.7 million square feet, and we had an additional three under development totaling 685,000 square feet as of December 31, 2021. We enter into long-term leases for these properties prior to commencing development, with triple-net structures and multiple extension options and rent escalators. Additionally, our tenants’ funding of the costs to fully power and equip these properties significantly enhances the value of these properties and creates high barriers to exit for such tenants.

We believe that our properties and team collectively complement our Defense/IT Locations strategy due to our:

•properties’ proximity to defense installations and other knowledge- and technology-based government demand drivers. Such proximity is generally preferred and often required for our tenants to execute their missions. Specifically, our:

•office properties are proximate to such mission-critical facilities as Fort George G. Meade (which houses over 100 Department of Defense organizations and agencies, including those engaged in signals intelligence, such as U.S. Cyber Command and Defense Information Systems Agency) and Redstone Arsenal (one of the largest defense installations in the United States, housing priority missions such as Army procurement, missile defense, space exploration and research and development, testing and engineering of advanced weapons systems); and

•data center shells are located in Northern Virginia, proximate to the MAE-East Corridor, which is a major Network Access Point in the United States for interconnecting traffic between Internet service providers;

•well-established relationships with the USG and its contractors;

•extensive experience in developing:

•high quality office properties;

•secured, specialized space, with the ability to satisfy the USG’s unique needs (including SCIF and ATFP requirements); and

•data center shells to customer specifications within very condensed timeframes to accommodate time-sensitive tenant demand; and

•depth of knowledge, specialized skills and credentialed personnel in operating highly-specialized properties with complex space and security-oriented needs.

Regional Office Strategy: While Defense/IT Locations are our primary focus, we also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region due to our strong market knowledge in that region. We believe that these submarkets possess the following favorable characteristics: (1) mixed-use, lifestyle-oriented locations with a robust residential and retail base; (2) proximity to public transportation and major transportation routes; (3) an educated workforce; and (4) a diverse employment base. As of December 31, 2021, we owned eight Regional Office properties, representing 11.6% of our office and data center shell portfolio’s annualized rental revenue. These properties were comprised of: three high-rise Baltimore City properties proximate to the city’s waterfront; four Northern Virginia properties proximate to Washington Metropolitan Area Metrorail stations and major interstates; and a newly-developed property in Washington, D.C.’s central business district.

Asset Management Strategy: We aggressively manage our portfolio to maximize the value and operating performance of each property through: (1) proactive property management and leasing; (2) maximizing tenant retention in order to minimize space downtime and additional capital associated with space rollover; (3) increasing rental rates where market conditions permit; (4) leasing vacant space; (5) achievement of operating efficiencies by increasing economies of scale and, where possible, aggregating vendor contracts to achieve volume pricing discounts; and (6) redevelopment when we believe property conditions and market demand warrant. We also continuously evaluate our portfolio and consider dispositions when properties no longer

meet our strategic objectives, or when capital markets and circumstances pertaining to such holdings otherwise warrant, in order to maximize our return on invested capital or support our capital strategy.

We aim to sustainably develop and operate our portfolio to create healthier work environments and reduce consumption of resources by: (1) developing new buildings designed to use resources with a high level of efficiency and low impact on human health and the environment during their life cycles through our participation in the U.S. Green Building Council’s Leadership in Energy and Environmental Design (“LEED”) program (targeting new office properties to meet or exceed LEED Silver certification standards or, when not possible, striving to otherwise incorporate LEED criteria into property designs); (2) adopting select LEED for Building Operations and Maintenance (“LEED O+M: Existing Buildings”) guidelines for much of our portfolio, including cleaning, recycling and energy reduction practices; (3) investing in systems and other equipment that reduce energy consumption; (4) investing in water saving features, such as low-flow toilets and sensor-activated sinks; and (5) participating in the annual Global Real Estate Sustainability Benchmark (“GRESB”) survey, which is widely recognized for measuring the environmental, social and governance (“ESG”) performance of real estate companies and funds. We earned an overall score of “Green Star” on the GRESB survey in each of the last seven years, representing the highest quadrant of achievement on the survey.

Property Development and Acquisition Strategy: We expand our operating portfolio primarily through property developments in support of our Defense/IT Locations strategy, and we have significant land holdings that we believe can further support that growth while serving as a barrier against competitive supply. We pursue development activities as market conditions and leasing opportunities support favorable risk-adjusted returns on investment, and therefore typically prefer properties to be significantly leased prior to commencing development. To a lesser extent, we may also pursue growth through acquisitions, seeking to execute such transactions at attractive yields and below replacement cost.

Capital Strategy: Our capital strategy is aimed at maintaining continuous access to capital irrespective of market conditions in the most cost-effective manner by:

•maintaining an investment grade rating to enable us to use debt comprised of unsecured, primarily fixed-rate debt (including the effect of interest rate swaps) from public markets and banks;

•using secured nonrecourse debt from institutional lenders and banks;

•managing our debt by monitoring, among other things: (1) the relationship of certain measures of earnings to our debt level and to certain capital costs; (2) the timing of debt maturities to ensure that maturities in any one year do not exceed levels that we believe we can refinance; (3) our exposure to changes in interest rates; and (4) our total and secured debt levels relative to our overall capital structure;

•monitoring capacity available under revolving credit facilities and equity offering programs to provide liquidity to fund investment activities;

•raising equity through issuances of common shares, joint venture structures for certain investments and, to a lesser extent, issuances of common equity in COPLP and preferred equity;

•recycling proceeds from sales of interests in properties to fund our investment activities and/or reduce overall debt;

•paying dividends at a level that is at least sufficient for us to maintain our REIT status; and

•continuously evaluating the ability of our capital resources to accommodate our plans for growth.

Industry Segments

As of December 31, 2021, our operations included the following reportable segments: Defense/IT Locations; Regional Office; Wholesale Data Center; and Other. Our Defense/IT Locations segment included the following sub-segments:

•Fort George G. Meade and the Baltimore/Washington Corridor (“Fort Meade/BW Corridor”);

•Northern Virginia Defense/IT Locations (“NoVA Defense/IT”);

•Lackland Air Force Base in San Antonio, Texas;

•locations serving the U.S. Navy (“Navy Support”). Properties in this sub-segment as of December 31, 2021 were proximate to the Washington Navy Yard in Washington, D.C., the Naval Air Station Patuxent River in Maryland and the Naval Surface Warfare Center Dahlgren Division in Virginia;

•Redstone Arsenal in Huntsville, Alabama; and

•data center shells in Northern Virginia (including 19 owned through unconsolidated real estate joint ventures).

As of December 31, 2021, Defense/IT Locations comprised 176 of our office and data center shell portfolio’s properties, representing 89.4% of its square feet in operations, while Regional Office comprised eight of the portfolio’s properties, or 9.9% of its square feet in operations. Our Wholesale Data Center segment is comprised of one property in Manassas, Virginia that we sold on January 25, 2022.

For information relating to our reportable segments, refer to Note 16 to our consolidated financial statements, which are included in a separate section at the end of this Annual Report on Form 10-K beginning on page F-1.

Human Capital

Our Workforce: As of December 31, 2021, our workforce was comprised of 405 employees based in Maryland, where we are headquartered, Texas, Virginia, Alabama and Washington, D.C. Our workforce has varying expertise, and includes:

•Building Technicians (178 employees), of which approximately 1% were female and approximately 34% of minority race. Building technicians are skilled trades professionals who perform mechanical maintenance, maintain our operating systems and service our buildings; and

•Office Staff, outlined below, of which approximately 57% were female and approximately 28% of minority race:

•Operations Management (68 employees): Property managers and support staff who service our tenant customer needs.

•Asset Management and Leasing (11 employees): Customer-facing leaders who drive the financial performance of our assets.

•Development and Construction (29 employees): Project managers and support staff who drive our development pipeline and interior design.

•Finance and Accounting (64 employees): Professionals who manage our financial activities.

•Company Support Functions (42 employees): Includes Human Resources, Investor Relations, Investments, Legal, Marketing, Information Technology, Facility Security and Corporate Administrative Support.

•Senior Leadership (13 employees): Our business line and Company leaders, including our Named Executive Officers, who interface with our Board of Trustees and shareholders and manage our business strategy, functional activities, risk and overall success.

In support of our Defense/IT Locations strategy, approximately one-third of our employees carry government credentials.

We operate in markets in which we compete for human capital. We rely on our employees to drive our success and we support them with a variety of programs to enhance their workplace engagement and job fulfillment.

Culture and Workforce Engagement: We develop and reinforce our culture by emphasizing our core values, illustrated by the actiiVe acronym. actiiVe stands for: Accountability, Commitment, Teamwork, Integrity, Innovation, Value Creation and Excellence. These values are intended to serve as a compass to our workforce to inform behavior and fuel our success.

We believe in equal opportunity, engagement and ethics. All employees must adhere to our Code of Business Conduct. We survey our workforce annually to measure engagement, use the feedback to enhance engagement and believe that this has helped us achieve annual “best workplace” honors for over a decade.

Compensation Program: Our compensation philosophy is driven by accountability, which results in a pay-for-performance structure. Our compensation program includes: base salary; an annual cash bonus program based on the achievement of individual, business unit and company objectives; health and welfare benefits; a retirement savings plan with a company match; financially-supported learning programs; and employee recognition programs. We also grant common equity to all new full-time employees and provide our senior management team and high performers with the ability to earn additional grants to align their interests with those of our shareholders and to incent retention.

Wellbeing and Safety: We view wellbeing as including five pillars: Physical, Emotional, Career, Financial and Community. We design programs to support each of these pillars. We directly incent wellbeing behaviors through a points-driven program each year. Employees who achieve the points threshold receive reductions in medical premiums or contributions to their health savings accounts. We believe this program enhances employee wellbeing and reduces medical costs.

Safety is a key part of our employee wellbeing, largely weighted in the Physical pillar. Recognizing this, we conduct job-tailored safety training on an ongoing basis. We also monitor our workers’ compensation claims to measure the effectiveness of our safety program.

With wellbeing and safety in mind, in response to the COVID-19 pandemic, we continue to focus on safety in the operations of our properties and workplaces through various protocols, including extensive communication with employees, contact tracing and the use of company-provided personal protective equipment.

Talent Development: We aim to attract, retain and develop our top talent throughout the employment cycle in order to enhance our talent pool. During 2021, our workforce size did not change significantly, with 49 new hires and 50 departures (an attrition rate of approximately 12%).

We offer robust learning programs to all employees, including educational assistance for college-level and vocational degree programs, and cover all expenses for licenses and certifications, management and leadership courses, key skills training and industry and professional conferences. Further, we offer internship programs to facilitate teaching and learning from others.

Community Engagement: We encourage employee engagement with our communities to facilitate personal growth and connection and to enhance our citizenship within our communities. We provide a platform for employees to engage with communities by contributing time, effort, money and expertise, which includes providing employees eight hours of paid time per year to engage in volunteer activities to serve our community directly in a company-organized team or individual format. Our employees select community non-profits for Corporate giving grants and for volunteer time contributions. We empower our employees to become involved and fuel our success in community partnerships.

Competition

The commercial real estate market is highly competitive. Numerous commercial landlords compete with us for tenants. Some of the properties competing with ours may be newer or in more desirable locations, or the competing properties’ owners may be willing to accept lower rents. We also compete with our own tenants, many of whom have the right to sublease their space. The competitive environment for leasing is affected considerably by a number of factors including, among other things, changes in economic conditions and supply of and demand for space. These factors may make it difficult for us to lease existing vacant space and space associated with future lease expirations at rental rates that are sufficient to produce acceptable operating cash flows.

We occasionally compete for the acquisition of land and commercial properties with many entities, including other publicly-traded commercial REITs. Competitors for such acquisitions may have substantially greater financial resources than ours. In addition, our competitors may be willing to accept lower returns on their investments or may be willing to incur higher leverage.

We also compete with many entities, including other publicly-traded commercial office REITs, for capital. This competition could adversely affect our ability to raise capital we may need to fulfill our capital strategy.

In addition, we compete with many entities for talent. If there is an increase in the costs for us to retain employees or if we otherwise fail to attract and retain such employees, our business and operating results could be adversely effected.

Item 1A. Risk Factors

Set forth below are risks and uncertainties relating to our business and the ownership of our securities. These risks and uncertainties may lead to outcomes that could adversely affect our financial position, results of operations, cash flows or ability to make expected distributions to our shareholders. You should carefully consider each of these risks and uncertainties, along with all of the information in this Annual Report on Form 10-K and its Exhibits, including our consolidated financial statements and notes thereto for the year ended December 31, 2021 included in a separate section at the end of this report beginning on page F-1.

Risks Associated with the Real Estate Industry and Our Properties

Our performance and asset value are subject to risks associated with our properties and with the real estate industry. Real estate investments are subject to various risks and fluctuations in value and demand, many of which are beyond our control. Our performance and the value of our real estate assets may decline due to conditions in the general economy and the real estate industry, which could adversely affect our financial position, results of operations, cash flows or ability to make expected distributions to our shareholders. These conditions include, but are not limited to:

•downturns in national, regional and local economic environments, including increases in the unemployment rate and inflation or deflation;

•competition from other properties;

•trends in office real estate that may adversely affect future demand, including remote work and flexible work arrangements, open workspaces and coworking spaces;

•deteriorating local real estate market conditions, such as oversupply, reduction in demand and decreasing rental rates;

•declining real estate valuations;

•adverse developments concerning our tenants, which could affect our ability to collect rents and execute lease renewals;

•government actions and initiatives, including risks associated with the impact of prolonged government shutdowns and budgetary reductions or impasses, such as a reduction of rental revenues, non-renewal of leases and/or reduced or delayed demand for additional space by our strategic customers;

•increasing operating costs, including insurance, utilities, real estate taxes and other expenses, some of which we may not be able to pass through to tenants;

•increasing vacancies and the need to periodically repair, renovate and re-lease space;

•increasing interest rates and unavailability of financing on acceptable terms or at all;

•unavailability of financing for potential purchasers of our properties;

•adverse changes resulting from the COVID-19 pandemic, and similar pandemics, along with restrictive measures instituted to prevent spread, on our business, the real estate industry and national, regional and local economic conditions;

•adverse changes in taxation or zoning laws;

•potential inability to secure adequate insurance;

•adverse consequences resulting from civil disturbances, natural disasters, terrorist acts or acts of war;

•adverse consequences due to the impact of climate change; and

•potential liability under environmental or other laws or regulations.

Our business may be affected by adverse economic conditions. Our business may be affected by adverse economic conditions in the United States economy or real estate industry as a whole or by the local economic conditions in the markets in which our properties are located, including the impact of high unemployment, inflation or deflation and constrained credit. Adverse economic conditions could increase the likelihood of tenants encountering financial difficulties, including bankruptcy, insolvency or general downturn of business, and as a result could increase the likelihood of tenants defaulting on their lease obligations to us. Such conditions could also decrease our likelihood of successfully renewing tenants at favorable terms or leasing vacant space in existing properties or newly-developed properties. In addition, such conditions could disrupt the operations, or profitability, of our business or increase the level of risk that we may not be able to obtain new financing for development activities, refinancing of existing debt, acquisitions or other capital requirements at reasonable terms, if at all.

We may suffer adverse consequences as a result of our reliance on rental revenues for our income. We earn revenue from leasing our properties. Certain of our operating costs do not necessarily fluctuate in relation to changes in our rental revenue. This means that these costs will not necessarily decline and may increase even if our revenues decline.

For new tenants or upon expiration of existing leases, we generally must make improvements and pay other leasing costs for which we may not receive increased rents. We also make building-related capital improvements for which tenants may not reimburse us.

If our properties do not generate revenue sufficient to meet our operating expenses and capital costs, we may need to borrow additional amounts to cover these costs. In such circumstances, we would likely have lower profits or possibly incur losses. We may also find in such circumstances that we are unable to borrow to cover such costs, in which case our operations could be adversely affected.

In addition, the competitive environment for leasing is affected considerably by a number of factors including, among other things, changes due to economic factors such as supply and demand. These factors may make it difficult for us to lease existing vacant space and space associated with future lease expirations at rental rates that are sufficient to meet our short-term capital needs.

We rely on the ability of our tenants to pay rent and would be harmed by their inability to do so. Our performance depends on the ability of our tenants to fulfill their lease obligations by paying their rental payments in a timely manner. As a result, we would be harmed if one or more of our major tenants, or a number of our smaller tenants, were to experience financial difficulties, including bankruptcy, insolvency, prolonged government shutdown or general downturn of business.

We may be adversely affected by developments concerning our major tenants or the USG and its contractors, including prolonged shutdowns of the government and actual, or potential, reductions in government spending targeting knowledge- and technology-based activities. As of December 31, 2021, our 10 largest tenants accounted for 63.6% of our total annualized rental revenue, the three largest of these tenants accounted for 50.5%, and the USG, our largest tenant, accounted for 35.6%. We calculate annualized rental revenue by multiplying by 12 the sum of monthly contractual base rents (ignoring free rent in effect and rent associated with tenant funded landlord costs) and estimated monthly expense reimbursements under active leases in our portfolio as of December 31, 2021; with regard to properties owned through unconsolidated real estate joint ventures, we include the portion of annualized rental revenue allocable to our ownership interest. For additional information regarding our tenant concentrations, refer to the section entitled “Concentration of Operations” within the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Most of our leases with the USG provide for a series of one-year terms. The USG may terminate its leases if, among other reasons, the United States Congress fails to provide funding. We would be harmed if any of our largest tenants fail to make rental payments to us over an extended period of time, including as a result of a prolonged government shutdown, or if the USG elects to terminate some or all of its leases and the space cannot be re-leased on satisfactory terms.

As of December 31, 2021, 87.5% of our office and data center shell properties’ total annualized rental revenue was from Defense/IT Locations, and we expect to maintain a similarly high revenue concentration from properties in these locations. A reduction in government spending targeting the activities of the government and its contractors (such as knowledge- and technology-based defense and security activities) in these locations could adversely affect our tenants’ ability to fulfill lease obligations, renew leases or enter into new leases and limit our future growth from properties in these locations. Moreover, uncertainty regarding the potential for future reduction in government spending targeting such activities could also decrease or delay leasing activity from tenants engaged in these activities.

Our future ability to fuel growth through data center shell development may be adversely affected should we suffer a loss of future development opportunities with our data center shell customer. Data center shells have been a significant growth driver for us in recent years, enabling us to develop and place into service fully-occupied, single-tenant properties, with long-term leases and rent escalators. These properties have garnered the interest of outside investors, enabling us to raise capital by selling ownership interests through joint venture structures in recent years at favorable profit margins, and to apply the proceeds towards other development opportunities. Our data center shell activity is concentrated with one customer. If that customer no longer chooses to allocate development opportunities to us, we may have limited opportunities to continue to use data center shells as a growth driver and possible source of future capital.

We may suffer economic harm in the event of a decline in the real estate market or general economic conditions in the Mid-Atlantic region, particularly in the Greater Washington, DC/Baltimore region, or in particular business parks. Most of our properties are located in the Mid-Atlantic region of the United States, particularly in the Greater Washington, DC/Baltimore region. Many of our properties are also concentrated in business parks in which we own most of the properties. Consequently, our portfolio of properties is not broadly distributed geographically. As a result, we would be harmed by a decline in the real estate market or general economic conditions in the Mid-Atlantic region, the Greater Washington, DC/Baltimore region or the business parks in which our properties are located.

We would suffer economic harm if we were unable to renew our leases on favorable terms. When leases expire, our tenants may not renew or may renew on terms less favorable to us than the terms of their original leases. If a tenant vacates a property, we can expect to experience a vacancy for some period of time, as well as incur higher leasing costs than we would likely incur if a tenant renews. As a result, we may be harmed if we experience a high volume of tenant departures at the end of their lease terms.

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 coworking spaces. These practices enable businesses to reduce their space requirements. These trends, some of which could accelerate as a result of changes in work practices during the COVID-19 pandemic, could erode demand for commercial office space and, in turn, place downward pressure on occupancy, rental rates and property valuations.

We may encounter a significant decline in the value of our real estate. The value of our real estate could be adversely affected by general economic and market conditions connected to a specific property or property type, a market or submarket, a broader economic region or the office real estate industry. Examples of such conditions include a broader economic recession, declining demand and decreases in market rental rates and/or market values of real estate assets. If our real estate assets significantly decline in value, it could result in our recognition of impairment losses. Moreover, a decline in the value of our real estate could adversely affect the amount of borrowings available to us under future credit facilities and other loans.

We may not be able to compete successfully with other entities that operate in our industry. The commercial real estate market is highly competitive. Numerous commercial properties compete with our properties for tenants; some of the properties competing with ours may be newer or in more desirable locations, or the competing properties’ owners may be willing to accept lower rates than are acceptable to us. In addition, we compete for the acquisition of land and commercial properties with many entities, including other publicly-traded REITs; competitors for such acquisitions may have substantially greater financial resources than ours, or may be willing to accept lower returns on their investments or incur higher leverage.

Real estate investments are illiquid, and we may not be able to dispose of properties on a timely basis when we determine it is appropriate to do so. Real estate investments can be difficult to sell and convert to cash quickly, especially if market conditions, including real estate lending conditions, are not favorable. Such illiquidity could limit our ability to fund capital needs or quickly change our portfolio of properties in response to changes in economic or other conditions. Moreover, under certain circumstances, the Internal Revenue Code imposes penalties on a REIT that sells property held for less than two years and limits the number of properties it can sell in a given year.

We may be unable to successfully execute our plans to develop additional properties. Although the majority of our investments are in operating properties, we also develop and redevelop properties, including some that are not fully pre-leased. When we develop or redevelop properties, we assume a number of risks, including, but not limited to, the risk of: actual costs exceeding our budgets; conditions or events occurring that delay or preclude our ability to complete the project as originally planned or at all; projected leasing not occurring; and not being able to obtain financing to fund property development activities.

We may suffer adverse effects from acquisitions of commercial real estate properties. We may pursue acquisitions of existing commercial real estate properties as part of our property development and acquisition strategy. Acquisitions of commercial properties entail risks, such as the risk that we may not be in a position, or have the opportunity in the future, to make suitable property acquisitions on advantageous terms and/or that such acquisitions fail to perform as expected.

We may pursue selective acquisitions of properties in regions where we have not previously owned properties. These acquisitions may entail risks in addition to those we face with acquisitions in more familiar regions, such as our not sufficiently anticipating conditions or trends in such regions and therefore not being able to operate the acquired properties profitably.

In addition, we may acquire properties that are subject to liabilities in situations where we have no recourse, or only limited recourse, against the prior owners or other third parties with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it. Examples of unknown liabilities with respect to acquired properties include, but are not limited to:

•liabilities for remediation of disclosed or undisclosed environmental contamination;

•claims by tenants, vendors or other persons dealing with the former owners of the properties;

•liabilities incurred in the ordinary course of business; and

•claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.

Data center space in certain of our office properties may be difficult to reposition for alternative uses. Certain of our office properties contain data center space, which is highly specialized space containing extensive electrical and mechanical systems that are uniquely designed to run and maintain banks of computer servers. Data centers are subject to obsolescence risks. If we need to reposition such space for another use, the renovations required to do so could be difficult and costly, and we may, as a result, deem such renovations to be impractical.

We may be subject to possible environmental liabilities. We are subject to various Federal, state and local environmental laws, including air and water quality, hazardous or toxic substances and health and safety. These laws can impose liability on current and prior property owners or operators for the costs of removal or remediation of hazardous substances released on a property, even if the property owner was not responsible for, or even aware of, the release of the hazardous substances. Costs resulting from environmental liability could be substantial. The presence of hazardous substances on our properties may also adversely affect occupancy and our ability to sell or borrow against those properties. In addition to the costs of government claims under environmental laws, private plaintiffs may bring claims for personal injury or other reasons. Additionally, various laws impose liability for the costs of removal or remediation of hazardous substances at the disposal or treatment facility; anyone who arranges for the disposal or treatment of hazardous substances at such a facility is potentially liable under such laws.

Although most of our properties have been subject to varying degrees of environmental assessment, many of these assessments are limited in scope and may not include or identify all potential environmental liabilities or risks associated with the property. Identification of new compliance concerns or undiscovered areas of contamination, changes in the extent or known scope of contamination, discovery of additional sites, human exposure to the contamination or changes in cleanup or compliance requirements could result in significant costs to us.

We may be adversely affected by natural disasters and the effects of climate change. Natural disasters, including earthquakes and severe storms could adversely impact our properties. We could also over time be adversely impacted by the effects of climate change on our properties, including the potential for more frequent or destructive severe weather events and rising sea levels. Such events could adversely affect our properties in a number of ways, including, but not limited to: declining demand for space; our ability to operate them effectively and profitably; their valuations; and our ability to sell them or use them as collateral for future debt. We could also be adversely affected by regulatory changes made in response to climate change that increase our costs to operate and develop properties.

Terrorist attacks or incidents related to social unrest may adversely affect the value of our properties, our financial position and cash flows. We have significant investments in properties located in large metropolitan areas or near military installations. Future terrorist attacks or incidents related to social unrest could directly or indirectly damage our properties or cause losses that materially exceed our insurance coverage. After such an attack or incident, tenants in these areas may choose to relocate their businesses to areas of the United States that may be perceived to be less likely targets of future terrorist activity or unrest, and fewer customers may choose to patronize businesses in these areas. This in turn would trigger a decrease in the demand for space in these areas, which could increase vacancies in our properties and force us to lease space on less favorable terms.

We may be subject to other possible liabilities that would adversely affect our financial position and cash flows. Our properties may be subject to other risks related to current or future laws, including laws relating to zoning, development, fire and life safety requirements and other matters. These laws may require significant property modifications in the future and could result in the levy of fines against us. In addition, although we believe that we adequately insure our properties, we are subject to the risk that our insurance may not cover all of the costs to restore a property that is damaged by a fire or other catastrophic events, including acts of war or, as mentioned above, terrorism.

We may be subject to increased costs of insurance and limitations on coverage. Our portfolio of properties is insured for losses under our property, casualty and umbrella insurance policies. These policies include coverage for acts of terrorism. Future changes in the insurance industry’s risk assessment approach and pricing structure may increase the cost of insuring our properties and decrease the scope of insurance coverage. Most of our loan agreements contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs, or at all, in the future. In addition, if lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance and/or refinance our properties and execute our growth strategies.

We may suffer economic harm as a result of the actions of our partners in real estate joint ventures and other investments. We may invest in certain entities in which we are not the exclusive investor or principal decision maker. Investments in such entities may, under certain circumstances, involve risks not present when a third party is not involved, including the possibility that the other parties to these investments might become bankrupt or fail to fund their share of required capital contributions. Our partners in these entities may have economic, tax or other business interests or goals that are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives. Such investments may also lead to impasses on major decisions, such as whether or not to sell a property, because neither we nor the other parties to these investments may have full control over the entity. In addition, we may in certain circumstances be liable for the actions of the other parties to these investments.

Our business could be adversely affected by a negative audit by the USG. Agencies of the USG, including the Defense Contract Audit Agency and various agency Inspectors General, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The USG also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies. Any costs found to be misclassified may be subject to repayment. If an audit or investigation uncovers improper or illegal activities, we may be subject to civil or criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the USG. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.

Risks Associated with Financing and Other Capital-Related Matters

We are dependent on external sources of capital for growth. Because COPT is a REIT, it must distribute at least 90% of its annual taxable income to its shareholders. Due to this requirement, we are not able to significantly fund our investment activities using retained cash flow from operations. Therefore, our ability to fund these activities is dependent on our ability to access debt or equity capital. Such capital could be in the form of new debt, common shares, preferred shares, common or preferred units in COPLP, joint venture funding or sales of interests in properties. These capital sources may not be available on favorable terms or at all. Moreover, additional debt financing may substantially increase our leverage and subject us to covenants that restrict management’s flexibility in directing our operations. Our inability to obtain capital when needed could have a material adverse effect on our ability to expand our business and fund other cash requirements.

We often use our Revolving Credit Facility to initially finance much of our investing activities and certain financing activities. Our lenders under this and other facilities could, for financial hardship or other reasons, fail to honor their commitments to fund our requests for borrowings under these facilities. If lenders default under these facilities by not being able or willing to fund a borrowing request, it would adversely affect our ability to access borrowing capacity under these facilities.

We may suffer adverse effects as a result of the indebtedness that we carry and the terms and covenants that relate to this debt. As of December 31, 2021, we had $2.3 billion in debt, the future maturities of which are set forth in Note 10 to our consolidated financial statements. Payments of principal and interest on our debt may leave us with insufficient cash to operate our properties or pay distributions to COPT’s shareholders required to maintain COPT’s qualification as a REIT. We are also subject to the risks that:

•we may not be able to refinance our existing indebtedness, or may only be able to do so on terms that are less favorable to us than the terms of our existing indebtedness;

•in the event of our default under the terms of our Revolving Credit Facility, COPLP could be restricted from making cash distributions to COPT unless such distributions are required to maintain COPT’s qualification as a REIT, which could result in reduced distributions to our equityholders or the need for us to incur additional debt to fund such distributions; and

•if we are unable to pay our debt service on time or are unable to comply with restrictive financial covenants for certain of our debt, our lenders could foreclose on our properties securing such debt and, in some cases, other properties and assets that we own.

Most of our unsecured debt is cross-defaulted, which means that failure to pay interest or principal on the debt above a threshold value will create a default on certain of our other debt.

If interest rates were to rise, our debt service payments on debt with variable interest rates would increase.

Our operations likely will not generate enough cash flow to repay all of our debt without additional borrowings, equity issuances and/or property sales. If we cannot refinance, extend the repayment date of, or otherwise raise funds required to repay, debt by its maturity date, we would default on such debt.

Our organizational documents do not limit the amount of indebtedness that we may incur. Therefore, we may incur additional indebtedness and become more highly leveraged, which could harm our financial position.

We may suffer adverse effects from changes in the method of determining LIBOR or the replacement of LIBOR with an alternative interest rate. Our variable-rate debt and interest rate swaps use as a reference rate the London Interbank Offered Rate (“LIBOR”), as calculated for the U.S. dollar (“USD-LIBOR”). In March 2021, the Financial Conduct Authority (“FCA”), the regulatory body in the United Kingdom that oversees LIBOR, announced that USD LIBOR will not be published after June 30, 2023. The FCA also established the spread that may be used to automatically convert contracts from LIBOR to the Secured Overnight Financing Rate (“SOFR”). As a result, banking regulators have encouraged banks to discontinue new LIBOR-based debt issuances by December 31, 2021. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form. The value of our debt or interest rate swaps tied to LIBOR, as well as interest rates on our current or future indebtedness, may also be impacted if LIBOR is limited or discontinued. The method of transitioning to an alternative reference rate may potentially be challenging, especially if we cannot agree with the respective counterparty about how to make the transition.

While we expect LIBOR to be available in substantially its current form until at least the end of June 30, 2023, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified. Alternative rates and other market changes related to the replacement of LIBOR, including the introduction of financial products and changes in market practices, may lead to risk modeling and valuation challenges, such as adjusting interest rate accrual calculations and building a term structure for an alternative rate. The introduction of an alternative rate also may create additional basis risk and increased volatility as alternative rates are phased in and utilized in parallel with LIBOR. Adjustments to systems and mathematical models to properly process and account for alternative rates will also be required, which may result in additional costs to us.

A downgrade in our credit ratings would materially adversely affect our business and financial condition. Our Senior Notes are currently rated investment grade by the three major rating agencies. These credit ratings are subject to ongoing evaluation by the credit rating agencies and can change. Any downgrades of our ratings or a negative outlook by the credit rating agencies would have a materially adverse impact on our cost and availability of capital and also could have a materially adverse effect on the market price of our common shares. In addition, since the variable interest rate spread and facility fees on certain of our debt, including our Revolving Credit Facility and a term loan facility, is determined based on our credit ratings, a downgrade in our credit ratings would increase the payments required on such debt.

We have certain distribution requirements that reduce cash available for other business purposes. Since COPT is a REIT, it must distribute at least 90% of its annual taxable income, which limits the amount of cash that can be retained for other business purposes, including amounts to fund development activities and acquisitions. Also, due to the difference in time between when we receive revenue and pay expenses and when we report such items for distribution purposes, it is possible that we may need to borrow funds for COPT to meet the 90% distribution requirement.

We may issue additional common or preferred equity that dilutes our shareholders’ interests. We may issue additional common shares or new issuances of preferred shares without shareholder approval. Similarly, we may issue additional common units, or issue preferred units, in COPLP for contributions of cash or property without approval by our shareholders. Our existing shareholders’ interests could be diluted if such additional issuances were to occur.

A number of factors could cause our security prices to decline. As is the case with any publicly-traded securities, certain factors outside of our control could influence the value of our equity security issuances. These conditions include, but are not limited to:

•market perception of REITs in general and office REITs in particular;

•market perception regarding our major tenants and sector concentrations;

•the level of institutional investor interest in us;

•general economic and business conditions;

•prevailing interest rates;

•our financial performance;

•our underlying asset value;

•market perception of our financial condition, performance, dividends and growth potential; and

•adverse changes in tax laws.

We may be unable to continue to make distributions to our shareholders at expected levels. We expect to make regular quarterly cash distributions to our shareholders. However, our ability to make such distributions depends on a number of factors, some of which are beyond our control. Some of our loan agreements contain provisions that could, in the event of default, restrict future distributions unless we meet certain financial tests or such payments or distributions are required to maintain COPT’s qualification as a REIT. Our ability to make distributions at expected levels is also dependent, in part, on other matters, including, but not limited to:

•continued property occupancy and timely receipt of rent from our tenants;

•the amount of future capital expenditures and expenses for our properties;

•our leasing activity and future rental rates;

•the strength of the commercial real estate market;

•our ability to compete;

•governmental actions and initiatives, including risks associated with the impact of a prolonged government shutdown or budgetary reductions or impasses;

•our costs of compliance with environmental and other laws;

•our corporate overhead levels;

•our amount of uninsured losses; and

•our decision to reinvest in operations rather than distribute available cash.

In addition, we can make distributions to holders of our common shares only after we make preferential distributions to holders of any outstanding preferred equity.

Our ability to pay distributions may be limited, and we cannot provide assurance that we will be able to pay distributions regularly. Our ability to pay distributions will depend on a number of things discussed elsewhere herein, including our ability to operate profitably and generate cash flow from our operations. We cannot guarantee that we will be able to pay distributions on a regular quarterly basis in the future. Additionally, the terms of some of our debt may limit our ability to make some types of payments and distributions in the event of certain default situations. This may limit our ability to make some types of payments, including payment of distributions on common or preferred shares, unless we meet certain financial tests or such payments or distributions are required to maintain COPT’s qualification as a REIT. As a result, if we are unable to meet the applicable financial tests, we may not be able to pay distributions in one or more periods. Furthermore, any new common or preferred shares that may be issued in the future for raising capital, financing acquisitions, share-based compensation arrangements or otherwise will increase the cash required to continue to pay cash distributions at current levels.

We may experience significant losses and harm to our financial condition if financial institutions holding our cash and cash equivalents file for bankruptcy protection. We believe that we maintain our cash and cash equivalents with high quality financial institutions. We have not experienced any losses to date on our deposited cash. However, we may incur significant losses and harm to our financial condition in the future if we were holding large sums of cash in any of these financial institutions at a time when they filed for bankruptcy protection.

Risks Associated with COVID-19 and Similar Pandemics

We may suffer further adverse effects from the COVID-19 pandemic, and similar pandemics, along with restrictive measures instituted to prevent spread. Since first being declared a pandemic by the World Health Organization in early March 2020, the coronavirus, or COVID-19, continues to spread world- and nation-wide as of the date of this filing. Since the beginning of 2021, the United States has significantly increased the proportion of the population that has received COVID-19 vaccines, and there is increased confidence that spread of COVID-19 can, to a large extent, be contained through vaccinations and wearing masks indoors in public. As a result, most restrictive measures that were previously instituted by governments and other authorities to control spread have been gradually lifted and an increased proportion of the population has resumed a return to normal activities. However, there continues to be significant uncertainty regarding the duration and extent of the pandemic due to factors such as the continuing spread of the virus, the pace of world- and nation-wide vaccination efforts, the continued emergence of new variants of the virus and the efficacy of vaccines against such variants.

COVID-19, and any similar pandemics should they occur, along with measures instituted to prevent spread, may adversely affect us in many ways, including, but not limited to:

•disruption of our tenants’ operations, which could adversely affect their ability, or willingness, to sustain their businesses and/or fulfill their lease obligations;

•our ability to maintain occupancy in our properties and obtain new leases for unoccupied and new development space at favorable terms or at all;

•shortages in supply of products or services from our and our tenants’ vendors that are needed for us and our tenants to operate effectively, and which could lead to increased costs for such products and services;

•access to debt and equity capital on attractive terms or at all. Severe disruption and instability in the global financial markets or deteriorations in credit and financing conditions may affect our or our tenants’ ability to access capital necessary to fund operations, refinance debt or fund planned investments on a timely basis, and may adversely affect the valuation of financial assets and liabilities;

•our and our tenants’ ability to continue or complete planned development, including the potential for delays in the supply of materials or labor necessary for development; and

•an increase in the pace of businesses implementing remote work arrangements over the long-term, which would adversely effect demand for office space.

The extent of the effect on our operations, financial condition and cash flows will be dependent on future developments, including the duration and extent of the pandemic, the prevalence, strength and duration of restrictive measures and the resulting effects on our tenants, potential future tenants, the commercial real estate industry and the broader economy, all of which are uncertain and difficult to predict. Moreover, some of the risks described in other risk factors set forth in this Annual Report on Form 10-K may be more likely to impact us as a result of COVID-19, and any similar pandemics should they occur, and the responses to curb spread, including, but not limited to: downturns in national, regional and local economic environments; deteriorating local real estate market conditions; and declining real estate valuations.

Other Risks

Our business could be adversely affected by security breaches through cyber attacks, cyber intrusions or otherwise. We face risks associated with security breaches and other significant disruptions of our information technology networks and related systems, which are essential to our business operations. Such breaches and disruptions may occur through cyber attacks or cyber intrusions over the Internet, malware, computer viruses, attachments to e-mails or by actions of persons inside our organization, including those with access to our systems. Because of our concentration on serving the USG and its contractors with a general focus on national security and information technology, we may be more likely to be targeted by cyber attacks, including by governments, organizations or persons hostile to the USG. We have preventative, detective and responsive measures in place to maintain the security and integrity of our networks and related systems that have to date enabled us to avoid breaches and disruptions that were individually, or in the aggregate, material. We also have insurance coverage in place in the event of significant future losses from breaches and disruptions. However, despite our activities to maintain the security and integrity of our networks and related systems, there can be no absolute assurance that these activities will be effective in mitigating these risks. A security breach involving our networks and related systems could disrupt our operations in numerous ways, including compromising the confidential information of our tenants, customers, vendors and employees, which could damage our relationships with such parties, and disrupting the proper functioning of our networks and systems on which much of our operations depend.

Our business could be adversely impacted if we are unable to attract and retain highly-qualified personnel. Our ability to operate effectively and succeed in the future is dependent in large part on our employees. Our Defense/IT Locations strategy in particular relies on the knowledge, specialized skills and credentialed personnel on our teams that serve those properties’ unique needs. We face very intense competition for highly-qualified personnel in the labor market. We also occasionally face even greater competition for personnel with certain skill sets or qualifications. As a result, we may not be successful in retaining our existing talent or attracting, training and retaining new personnel with the requisite skills. We may also find that we need to further increase compensation costs in response to this competition. Our business could be harmed by the loss of key employees, a significant number of employees or a significant number of employees in a specialized area of the Company.

We have certain provisions or statutes that may serve to delay or prevent a transaction or a change in control that would be advantageous to our shareholders from occurring. COPT’s Declaration of Trust limits ownership of its common shares by any single shareholder to 9.8% of the number of the outstanding common shares or 9.8% of the value of the outstanding common shares, whichever is more restrictive. COPT’s Declaration of Trust also limits ownership by any single shareholder of our common and preferred shares in the aggregate to 9.8% of the aggregate value of our outstanding common and preferred shares. We call these restrictions the “Ownership Limit.” COPT’s Declaration of Trust allows our Board of Trustees to exempt shareholders from the Ownership Limit. The Ownership Limit and the restrictions on ownership of our common shares may delay or prevent a transaction or a change of control that might involve a premium price for our common shares or otherwise be in the best interest of our shareholders.

Subject to the requirements of the New York Stock Exchange, our Board of Trustees has the authority, without shareholder approval, to issue additional securities on terms that could delay or prevent a change in control. In addition, our Board of Trustees has the authority to reclassify any of our unissued common shares into preferred shares. Our Board of Trustees may issue preferred shares with such preferences, rights, powers and restrictions as our Board of Trustees may determine, which could also delay or prevent a change in control.

In addition, various Maryland laws may have the effect of discouraging offers to acquire us, even if the acquisition would be advantageous to shareholders. Resolutions adopted by our Board of Trustees and/or provisions of our bylaws exempt us from

such laws, but our Board of Trustees can alter its resolutions or change our bylaws at any time to make these laws applicable to us.

COPT’s failure to qualify as a REIT would have adverse tax consequences, which would substantially reduce funds available to make distributions to our shareholders. We believe that COPT has qualified for taxation as a REIT for Federal income tax purposes since 1992. We plan for COPT to continue to meet the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. The determination that COPT is a REIT requires an analysis of various factual matters and circumstances that may not be totally within our control. For example, to qualify as a REIT, at least 95% of COPT’s gross income must come from certain sources that are specified in the REIT tax laws. COPT is also required to distribute to shareholders at least 90% of its annual taxable income. The fact that COPT holds most of its assets through COPLP and its subsidiaries further complicates the application of the REIT requirements. Even a technical or inadvertent mistake could jeopardize COPT’s REIT status. Furthermore, Congress and the Internal Revenue Service might make changes to the tax laws and regulations and the courts might issue new rulings that make it more difficult or impossible for COPT to remain qualified as a REIT.

If COPT fails to qualify as a REIT, it would be subject to Federal income tax at regular corporate rates. Also, unless the Internal Revenue Service granted us relief under certain statutory provisions, COPT would remain disqualified from being a REIT for four years following the year it first fails to qualify. If COPT fails to qualify as a REIT, it would have to pay significant income taxes and would therefore have less money available for investments or for distributions to our shareholders. In addition, if COPT fails to qualify as a REIT, it would no longer be required to pay distributions to shareholders. As a result of all these factors, COPT’s failure to qualify as a REIT could impair our ability to expand our business and raise capital and would likely have a significant adverse effect on the value of our shares.

We may be adversely impacted by changes in tax laws. At any time, U.S. federal tax laws or the administrative interpretations of those laws may be changed. We cannot predict whether, when or to what extent new U.S. federal tax laws, regulations, interpretations or rulings will be issued. In addition, while REITs generally receive certain tax advantages compared to entities taxed as C corporations, it is possible that future legislation could result in REITs having fewer tax advantages, and therefore becoming a less attractive investment alternative. As a result, changes in U.S. federal tax laws could negatively impact our operating results, financial condition and business operations, and adversely impact our shareholders.

Occasionally, changes in state and local tax laws or regulations are enacted that may result in an increase in our tax liability. Shortfalls 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, revenue or income.

Our tenants and contractual counterparties could be designated “Prohibited Persons” by the Office of Foreign Assets Control. The Office of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) maintains a list of persons designated as terrorists or who are otherwise blocked or banned (“Prohibited Persons”). OFAC regulations and other laws prohibit us from conducting business or engaging in transactions with Prohibited Persons. If a tenant or other party with whom we conduct business is placed on the OFAC list or is otherwise a party with whom we are prohibited from doing business, we would be required to terminate our lease or other agreement with them.

(1)This percentage is based upon all rentable square feet or megawatts under lease terms that were in effect as of December 31, 2021.

(2)Annualized rental revenue is the monthly contractual base rent as of December 31, 2021 (ignoring free rent then in effect and rent associated with tenant funded landlord assets) multiplied by 12, plus the estimated annualized expense reimbursements under existing leases. With regard to properties owned through unconsolidated real estate joint ventures, we include the portion of annualized rental revenue allocable to our ownership interest. We consider annualized rental revenue to be a useful measure for analyzing revenue sources because, since it is point-in-time based, it does not contain increases and decreases in revenue associated with periods in which lease terms were not in effect; historical revenue under generally accepted accounting principles does contain such fluctuations. We find the measure particularly useful for leasing, tenant and segment analysis. Our calculation of annualized rental revenue per occupied square foot excludes revenue of our reportable segments from leases not associated with our buildings.

(3)Represents properties owned through unconsolidated real estate joint ventures. The amounts reported above reflect 100% of the properties’ square footage but only reflect the portion of annualized rental revenue that was allocable to our ownership interest.

(1)Refer to definition provided on first page of Item 2 of this Annual Report on Form 10-K.

(2)Includes only ground leases.

(3)We sold this property on January 25, 2022. The annualized rental revenue of its scheduled lease expirations as of December 31, 2021 was as follows: $17.2 million in 2022; $2.4 million in 2023; $11,000 in 2024; $2.7 million in 2025; $27,000 in 2026; $29,000 in 2027; and $238,000 in 2028.

With regard to the office and data center shell portfolio leases reported above as expiring in 2022, we believe that the weighted average annualized rental revenue per occupied square foot for such leases as of December 31, 2021 was, on average, approximately 1.0% to 3.0% higher than estimated current market rents for the related space, with specific results varying by market.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

You should refer to our consolidated financial statements and the notes thereto as you read this section.

This section contains “forward-looking” statements, as defined in the Private Securities Litigation Reform Act of 1995, that are based on our current expectations, estimates and projections about future events and financial trends affecting the financial condition and operations of our business. Forward-looking statements can be identified by the use of words such as “may,” “will,” “should,” “could,” “believe,” “anticipate,” “expect,” “estimate,” “plan” or other comparable terminology. Forward-looking statements are inherently subject to risks and uncertainties, many of which we cannot predict with accuracy and some of which we might not even anticipate. Although we believe that the expectations, estimates and projections reflected in such forward-looking statements are based on reasonable assumptions at the time made, we can give no assurance that these expectations, estimates and projections will be achieved. Future events and actual results may differ materially from those discussed in the forward-looking statements. Important factors that may affect these expectations, estimates and projections include, but are not limited to:

•adverse changes in the real estate markets, including, among other things, increased competition with other companies;

•our ability to borrow on favorable terms;

•changes in our plans for properties or views of market economic conditions or failure to obtain development rights, either of which could result in recognition of significant impairment losses;

•our ability to satisfy and operate effectively under Federal income tax rules relating to real estate investment trusts and partnerships;

•possible adverse changes in tax laws;

•the dilutive effects of issuing additional common shares;

•our ability to achieve projected results;

•security breaches relating to cyber attacks, cyber intrusions or other factors; and

•environmental requirements.

We undertake no obligation to publicly update or supplement forward-looking statements.

Overview

Our 2021 was highlighted by:

•strong leasing results, including our:

•fourth consecutive year with development leasing in excess of one million square feet; and

•seventh consecutive year with a portfolio-wide tenant retention rate in excess of 70%;

•the refinancing of most of our debt, resulting in new unsecured debt issuances with lengthened and staggered future maturity timing and lower interest rates;

•capital raised from selling interests in data center shells through a newly-formed joint venture;

•our entry into a contract to sell our largest real estate investment and enable us to exit the wholesale data center business; and

•operating results that were not significantly affected by the COVID-19 pandemic.

We leased 3.9 million square feet in 2021, representing our fifth consecutive year with leasing in excess of 3.0 million. This leasing included:

•1.2 million square feet of development leasing in Defense/IT Locations, including 727,000 square feet in our Redstone Arsenal sub-segment;

•2.1 million square feet of renewal leasing, resulting in a portfolio-wide tenant retention rate of 74.2%. Strong tenant retention is key to our asset management strategy in order to maximize revenue (by avoiding downtime) and minimize leasing capital; and

•616,000 square feet of vacant space leasing, most of which was concentrated in the Fort Meade/BW Corridor sub-segment.

We believe that our 2021 leasing benefited from a continued:

•healthy defense spending environment, with bipartisan support for funding our national defense. We believe that successive increases in defense spending since 2016, including, most recently, in the National Defense Authorization Act for Fiscal Year 2022, have enhanced the USG and defense contractor tenants’ ability to invest in facility planning. This environment has helped fuel leasing demand, as has continued prioritization of spending allocations towards technology and innovation programs benefiting our Defense/IT Locations, including cyber, space, unmanned systems and artificial intelligence; and

•demand for data center shells. Our leasing included two new data center shells in Northern Virginia, the largest data center market in the world, and represented further expansion of our relationship with an existing customer. As of year end, we held land that would accommodate an additional 913,000 square feet in future data center shell development.

We believe these conditions bolstered tenant confidence levels for entering into long-term lease commitments, as evidenced by weighted average lease terms on our 2021 leasing of: 13.4 years on development leasing; 5.4 years on renewal leasing; and 8.2 years on vacant space leasing. Future leasing demand for our Defense/IT Locations could be delayed or diminish if this bipartisan support for funding national defense does not continue or if appropriations legislation to fund approved defense budgets face extended delays (including the USG’s 2022 fiscal year defense budget, which was authorized but was awaiting appropriations as of the date of this filing).

In 2021, we placed into service 766,000 square feet in eight newly-developed properties that were 87% leased as of December 31, 2021. These properties were predominantly Defense/IT Locations, the largest of which was a 348,000 square foot, 100% leased property in our NoVA Defense/IT sub-segment. We ended the year with 1.7 million square feet in properties under development that were 96% leased in aggregate, most of which were in our Redstone Arsenal and Data Center Shells sub-segments. Most of these properties were 100% leased and all but two were more than 80% leased. For further disclosure regarding our development underway as of year end, please refer to Item 2 of this Annual Report on Form 10-K.

We ended 2021 with lower leased and occupied percentages for our office and data center shell portfolio relative to December 31, 2020 (which was our highest year end portfolio-wide occupancy since 2001) due primarily to a property in our Redstone Arsenal sub-segment vacated by its tenant in late 2021 and newly-developed vacant space placed in service (most of which was in a Regional Office property). We ended 2021 with our office and data center shell portfolio 94.2% leased (compared to 94.8% as of December 31, 2020) while our Same Properties were 93.4% leased (compared to 93.8% as of December 31, 2020). Our year end portfolio-wide office and data center shell occupancy was 92.4% (compared to 94.1% as of December 31, 2020) and Same Properties occupancy was 91.3% (compared to 92.9% as of December 31, 2020).

As of December 31, 2021, we had scheduled lease expirations for 1.6 million square feet in 2022, representing 8.2% of our total occupied square feet and 9.4% of our total annualized rental revenue from office and data center shells, including:

•1.3 million square feet in our Defense/IT Locations segment, most of which we believe is mission-critical space to the tenants and therefore expect most of this space to be renewed; and

•327,000 square feet in our Regional Office segment, which included a 140,000 square foot known non-renewal for 2022, and which we believe otherwise carries significantly higher risk of non-renewal than our Defense/IT Locations space.

Please refer to the section below entitled “Occupancy and Leasing” for additional related disclosure.

In 2021, we refinanced most of our debt by issuing $1.4 billion in unsecured senior notes, including:

•$600.0 million of 2.75% Notes due 2031 issued at an initial offering price of 98.95% of their face value on March 11, 2021 for proceeds, after deducting underwriting discounts but before other offering expenses, of $589.8 million. We applied the proceeds from this issuance to purchase or redeem $350.0 million of 3.60% Senior Notes due 2023 and $250.0 million of 5.25% Senior Notes due 2024 for $373.1 million and $282.4 million, respectively, plus accrued interest. In connection with these purchases and redemptions, we recognized a loss on early extinguishment of debt in 2021 of $58.4 million. We used borrowings under our Revolving Credit Facility to fund the net cash outlay resulting from this refinancing;

•$400.0 million of 2.00% Notes due 2029 at an initial offering price of 99.97% of their face value on August 11, 2021 for proceeds, after deducting underwriting discounts but before other offering expenses, of $397.4 million. We used $100.0 million of the proceeds from this issuance to repay a portion of our term loan facility, $89.0 million to pay off a construction loan and most of the remaining proceeds to repay borrowings under our Revolving Credit Facility; and

•$400.0 million of 2.90% Notes due 2033 at an initial offering price of 99.53% of their face value on November 17, 2021 for proceeds, after deducting underwriting discounts but before other offering expenses, of $395.4 million. We used $336.4 million of the proceeds from this issuance to redeem $300.0 million of 5.00% Senior Notes due 2025 and $52.4 million to

pay off a fixed rate mortgage loan. In connection with these debt repayments, we recognized a loss on early extinguishment of debt in 2021 of $41.1 million.

As a result, from September 2020 (when we issued $400 million unsecured senior notes) to year end 2021, we issued $1.8 billion in unsecured senior notes, which enabled us to refinance $1.6 billion in debt, or 81% of our outstanding debt as of June 30, 2020, at weighted average interest rates on the newly-issued debt that were 1.1% lower than the weighted average interest rates on the debt we repaid. This also enabled us to lengthen and stagger the timing of our future debt maturities.

As in recent years, we raised equity in 2021 through the sale of interests in single tenant data center shell properties with the sale of a 90% interest in two such properties based on an aggregate property value of $118.8 million and retained a 10% interest in the properties through B RE COPT DC JV III LLC, a newly-formed joint venture. Our partner in the joint venture acquired the 90% interest from us for $106.9 million, the proceeds from which we used to repay borrowings under our Revolving Credit Facility. We recognized a gain of $40.2 million on this sale. Since 2019, we raised $558 million from the sale of interests in single tenant data center shell properties.

We also in 2021 sold a property that was previously removed from service from our data center shells sub-segment for $30.0 million, the proceeds from which we used to repay borrowings under our Revolving Credit Facility. We recognized a gain of $25.9 million on this sale.

In addition, we entered into a contract in December 2021 to sell 9651 Hornbaker Road in Manassas, Virginia, our largest real estate investment (in terms of book value) and only property in our Wholesale Data Center reportable segment, for $222.5 million. Our entry into this contract positioned us to exit the wholesale data center business and redeploy the resulting proceeds towards funding our Defense/IT Locations development pipeline. We completed this sale on January 25, 2022, resulting in a gain on sale of approximately $29 million, and used substantially all of the proceeds to pay down debt in order to free up borrowing capacity to fund future development.

Due to the collective effect of our 2021 activity, we ended the year with:

•approximately $190 million more debt relative to the end of 2020 that we were positioned to pay down by $216 million in January 2022 using the proceeds from our wholesale data center sale; and

•$724 million in borrowing capacity available under our Revolving Credit Facility to fund our investing and financing activities (which capacity was subsequently increased to $800 million in January 2022 following our pay down of the facility from our wholesale data center sale proceeds).

Net income in 2021 was $21.3 million lower than in 2020 due primarily to:

•lower income due to a $93.3 million increase in loss on early extinguishment of debt due to the extinguishments discussed above and $29.4 million gain on sale of investment in an unconsolidated joint venture that occurred in 2020; offset in part by

•higher income due to a $53.2 million loss on interest rate derivatives recognized in 2020 and $35.4 million increase in gain from sales of real estate due to the gains from the sales discussed above exceeding our gains in 2020.

Net operating income (“NOI”) from real estate operations, our segment performance measure discussed further below, increased $19.0 million from 2020 to 2021 due primarily to:

•a $27.6 million increase from developed and redeveloped properties placed into service; offset in part by

•a net decrease of $10.5 million from dispositions due to our sales of property interests in 2020 and 2021.

NOI from our Same Properties only changed marginally, increasing $1.8 million, or 0.6%, from 2020 to 2021. Our results of operations for these periods were not significantly affected by the COVID-19 pandemic. Additional disclosure comparing our 2021 and 2020 results of operations is provided below.

We discuss significant factors contributing to changes in our net income between 2021 and 2020 in the section below entitled “Results of Operations.” In addition, the section below entitled “Liquidity and Capital Resources” includes discussions of, among other things:

•how we expect to generate cash for short and long-term capital needs; and

•our commitments and contingencies.

We refer to the measures “annualized rental revenue” and “tenant retention rate” in various sections of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Annualized rental revenue is a measure that we use to evaluate the source of our rental revenue as of a point in time. It is

computed by multiplying by 12 the sum of monthly contractual base rents and estimated monthly expense reimbursements under active leases as of a point in time (ignoring free rent then in effect and rent associated with tenant funded landlord assets). Our computation of annualized rental revenue excludes the effect of lease incentives. We consider annualized rental revenue to be a useful measure for analyzing revenue sources because, since it is point-in-time based, it does not contain increases and decreases in revenue associated with periods in which lease terms were not in effect; historical revenue under generally accepted accounting principles in the United States of America (“GAAP”) does contain such fluctuations. We find the measure particularly useful for leasing, tenant, segment and industry analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.

We also refer to the measures “cash rents”, “straight-line rents”, and “committed costs” in the “Occupancy and Leasing” section of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Cash rents include monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). Straight-line rents includes annual minimum rents, net of abatements and lease incentives and excluding rent associated with tenant funded landlord assets, on a straight-line basis over the term of the lease, and estimated annual expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). We believe that cash rents and straight-line rents are useful measures for evaluating the rental rates of our leasing activity, including changes in such rates relative to rates that may have been previously in place, with cash rents serving as a measure to evaluate rents at the time rent payments commence, and straight-line rents serving as a measure to evaluate rents over lease terms. Committed costs includes tenant improvement allowances (excluding tenant funded landlord assets), leasing commissions and estimated turn key costs and excludes lease incentives; we believe this is a useful measure for evaluating our costs associated with obtaining new leases.

With regard to our operating portfolio square footage, occupancy and leasing statistics included below and elsewhere in this Annual Report on Form 10-K, amounts disclosed include total information pertaining to properties owned through unconsolidated real estate joint ventures except for amounts reported for annualized rental revenue, which represent the portion attributable to our ownership interest.

Effects of COVID-19

As of the date of this filing, spread of COVID-19 continues world- and nation-wide. Since the beginning of 2021, the United States has significantly increased the proportion of the population that has received COVID-19 vaccines, and there is increased confidence that spread of COVID-19 can, to a large extent, be contained through vaccinations and wearing masks indoors in public. As a result, most restrictive measures previously instituted to control spread have been gradually lifted and an increased proportion of the population has resumed a return to normal activities. However, there continues to be significant uncertainty regarding the duration and extent of the pandemic due to factors such as the continuing spread of the virus, the pace of world- and nation-wide vaccination efforts, the continued emergence of new variants of the virus and the efficacy of vaccines against such variants.

While the pandemic has adversely impacted the operations of much of the commercial real estate industry, we believe that we have been less susceptible to such impact due to our portfolio’s significant concentration in Defense/IT Locations. These properties are primarily occupied by the USG and contractor tenants engaged in what we believe are high-priority security, defense and IT missions. As a result, most of these properties were designated as “essential businesses,” and therefore exempt from many of the restrictions that otherwise have affected much of the commercial real estate industry. Furthermore, since the tenants in these properties are mostly the USG, or contractors of the USG who continue to be compensated by the USG for their services, we believe that their ability, and willingness, to fulfill their lease obligations have not been disrupted. Our Defense/IT Locations do include tenants serving as amenities to business parks housing our properties (such as restaurant, retail and personal service providers); while these tenants’ operations have been significantly disrupted by COVID-19, our annualized rental revenue from these tenants is not significant. As a result, our results of operations were not significantly affected by the pandemic. For the year ended December 31, 2021, our:

•Same Properties NOI from real estate operations increased marginally relative to 2020, and was only minimally affected by the pandemic-related effect of lower provisions for collectability losses in 2021 relative to 2020; and

•lease revenue collections were not significantly affected by the pandemic. After agreeing to deferred payment arrangements for approximately $2.6 million in lease receivables last year (most of which was repaid by June 30, 2021), we did not agree to significant additional arrangements in 2021.

While we do not currently expect that the pandemic will significantly affect our future results of operations, financial condition or cash flows, we believe that the impact will be dependent on future developments, including the duration and extent of the pandemic, the prevalence, strength and duration of restrictive measures and the resulting effects on our tenants, potential future tenants, the commercial real estate industry and the broader economy, all of which are uncertain and difficult to predict. Nevertheless, we believe at this time that there is more inherent risk associated with the operations of our Regional Office properties than our Defense/IT Locations.

While our development leasing and ability to renew leases scheduled to expire have not been significantly affected by the pandemic, we do believe that the impact of the restrictive measures and the economic uncertainty caused by the pandemic impacted our timing and volume of vacant space leasing, and may continue to do so in the future, particularly for our Regional Office properties.

The pandemic enhances the risk of us being able to stay on pace to complete development and begin operations on schedule due to the potential for delays from: jurisdictional permitting and inspections; factories’ ability to provide materials; and possible labor shortages. These types of issues have not significantly affected us to date but could in the future, depending on pandemic related developments.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with GAAP, which require us to make certain estimates and assumptions. A summary of our significant accounting policies is provided in Note 2 to our consolidated financial statements. The following section is a summary of certain aspects of those accounting policies involving estimates or assumptions that (1) involve a significant level of estimation uncertainty and (2) have had or are reasonably likely to have a material impact on our financial condition or results of operations. It is possible that the use of different reasonable estimates or assumptions could result in materially different amounts being reported in our consolidated financial statements. While reviewing this section, refer to Note 2 to our consolidated financial statements, including terms defined therein.

Assessment of Lease Term as Lessor

As discussed above, a significant portion of our portfolio is leased to the USG, and the majority of those leases consist of a series of one-year renewal options (with defined rent escalations upon renewal), and/or provide for early termination rights. Applicable accounting guidance requires us to recognize minimum rental payments on operating leases, net of rent abatements, on a straight-line basis over the term of each lease. We estimate a tenant’s lease term at the lease commencement date and do not subsequently reassess such term unless the lease is modified. When estimating a tenant’s lease term, we use judgment in contemplating the significance of: any penalties a tenant may incur should it choose not to exercise any existing options to extend the lease or exercise any existing options to terminate the lease; and economic incentives to the tenant based on any existing contract, asset, entity or market-based factors associated with the lease. Factors we consider in making this assessment include the uniqueness of the purpose or location of the property, the availability of a comparable replacement property, the relative importance or significance of the property to the continuation of the lessee’s line of business and the existence of tenant leasehold improvements or other assets whose value would be impaired by the tenant vacating or discontinuing use of the leased property. For most of our leases with the USG, our estimates of lease term conclude that exercise of existing renewal options, or continuation of such leases without exercising early termination rights, is reasonably certain as it relates to the expected lease end date. As a result, our recognition of minimum rents on these leases includes the effect of annual rent escalations over our estimate of the lease term (including on one-year renewal options) and our depreciation and amortization of costs incurred on these leases is recognized over the lease term. An over-estimate of the term of these leases by us could result in the write-off of any recorded assets associated with straight-line rental revenue and acceleration of depreciation and amortization expense associated with costs we incurred related to these leases. We had no significant USG leases with lease terms determined to have been over-estimated during the reporting periods included herein.

Impairment of Long-Lived Assets

We assess the asset groups associated with each of our properties for indicators of impairment quarterly or when circumstances indicate that an asset group may be impaired. If our analyses indicate that the carrying values of certain properties’ asset groups may be impaired, we perform a recoverability analysis for such asset groups. If and when our plans change for a property, we revise our recoverability analyses to use the cash flows expected from the operations and eventual disposition of such property using holding periods that are consistent with our revised plans. In our accounting for impairment of long-lived assets, we estimate property fair values based on contract prices, indicative bids, discounted cash flow analyses or comparable sales analyses. We estimate cash flows used in performing impairment analyses based on our plans for the property and our views of market and economic conditions. Our estimates consider items such as current and future market rental and occupancy rates, estimated operating and capital expenditures and recent sales data for comparable properties; most of these items are influenced by market data obtained from real estate leasing and brokerage firms and our direct experience with the properties and their markets. Our determination of appropriate capitalization or discount rates for use in estimating property fair values also requires significant judgment and is typically based on many factors, including the prevailing rate for the market or submarket, as well as the quality and location of the property.

Since asset groups associated with properties held for sale are carried at the lower of their carrying values (i.e., cost less accumulated depreciation and any impairment loss recognized, where applicable) or estimated fair values less costs to sell, decisions by us to sell certain properties will result in impairment losses if the carrying values of the specific properties’ asset groups classified as held for sale exceed such properties’ estimated fair values less costs to sell. Our estimates of fair value

consider matters such as recent sales data for comparable properties and, where applicable, contracts or the results of negotiations with prospective purchasers. These estimates are subject to revision as market conditions, and our assessment of such conditions, change.

Historically, future market rental and occupancy rates have tended to be the most variable assumption in our impairment analyses of properties to be held and used; while changes in these assumptions can significantly affect our estimates of property undiscounted future cash flows in our recoverability analyses, such changes historically have not usually resulted in impairment losses since the resulting recoverability analyses still have tended to exceed the carrying value of the property asset groups. Historically, our recognition of impairment losses has most often occurred due to changes in our estimates of future cash flows resulting from a change in our plans for a property, such as a decision by us to sell or shorten our expected holding period for a property or to not develop a property. Changes in the estimated future cash flows due to changes in our plans for a property or significant changes in our views regarding property market and economic conditions and/or our ability to obtain development rights could result in recognition of impairment losses that could be substantial.

The USG’s concentration increased from 2020 to 2021 due primarily to new properties placed in service in which it is a tenant.

Concentration of Office and Data Center Shell Properties by Segment

The table below sets forth the segment allocation of our annualized rental revenue of office and data center shell properties as of the end of the last three calendar years:


	Percentage of Annualized Rental Revenue of Office and Data Center Shell Properties as of December 31,						Number of Properties as of December 31,
Region	2021		2020		2019		2021	2020	2019
Defense/IT Locations:
Fort Meade/BW Corridor	47.0	%	47.5	%	51.3	%	90	89	88
NoVA Defense/IT	13.3	%	11.2	%	10.9	%	14	13	13

(1)Includes lease terminations and space reductions occurring in connection with lease renewals.

With regard to changes in occupancy from December 31, 2020 to December 31, 2021:

•Total: Decrease was due primarily to a 121,000 square foot property in our Redstone Arsenal sub-segment vacated by its tenant in late 2021 and 137,000 square feet in newly-developed vacant space placed in service (most of which was in a Regional Office property);

•Fort Meade/BW Corridor: Decrease was due primarily to a 63,000 square foot property vacated by its tenant (which was subsequently leased to a new tenant that will take occupancy in 2022) and 46,000 square feet in newly-developed space in a property placed in service;

•NoVA Defense/IT: Increase was due primarily to a 348,000 square foot fully-occupied property placed in service;

•Navy Support: Decreased despite its 76.1% tenant retention rate in 2021 due to minimal leasing of vacant space;

•Redstone Arsenal: Decreased due primarily to a 121,000 square foot property vacated by its tenant in late 2021;

•Regional Office: Decreased due to 81,000 square feet in newly-developed vacant space in a property placed in service, space vacated with its 63.2% tenant retention rate and minimal leasing of vacant space. This segment included properties in Baltimore City, two sub-markets in Northern Virginia and Washington, D.C. We believe that the restrictive measures and economic uncertainty caused by the pandemic impacted leasing demand for this segment, and may continue to do so in the future. As of December 31, 2021, we had scheduled lease expirations in 2022 for 327,000 square feet, or 17.5%, of this segment’s occupied square feet (including a 140,000 square foot space that we know is not renewing in 2022); and

•Other: Included two properties totaling 157,000 square feet in Aberdeen, Maryland.

In 2021, we leased 3.9 million square feet, including 1.2 million square feet of development space in Defense/IT Locations, with weighted average lease terms of 13.4 years.

In 2021, we renewed leases on 2.1 million square feet, representing a tenant retention rate of 74.2%. The cash rents of these renewals (totaling $33.34 per square foot) decreased on average by approximately 2.2% and the straight-line rents (totaling $33.87 per square foot) increased on average by approximately 5.2% relative to the leases previously in place for the space. The renewed leases had a weighted average lease term of approximately 5.4 years, with average escalations per year of 2.3%, and the per annum average committed costs associated with completing the leasing was approximately $2.99 per square foot. The decrease in cash rents on renewals was attributable primarily to per annum rent escalation terms of the previous leases that increased rents over the lease terms by amounts exceeding the increases in the applicable market rental rates.

In 2021, we also completed leasing on 616,000 square feet of vacant space. The cash rents of this leasing totaled $26.95 per square foot and the straight-line rents totaled $27.56 per square foot; these leases had a weighted average lease term of approximately 8.2 years, with average escalations per year of 2.9%, and the per annum average committed costs associated with completing this leasing was approximately $8.60 per square foot.
