Table of Contents Item 1. BUSINESS

General

UDR is a self-administered real estate investment trust, or REIT, that owns, operates, acquires, renovates, develops, redevelops, disposes of, and manages multifamily apartment communities in targeted markets located in the United States. At December 31, 2023, our consolidated real estate portfolio consisted of 168 communities located in 21 markets, consisting of 55,550 completed apartment homes, which are held directly or through our subsidiaries, including the Operating Partnership and the DownREIT Partnership, and consolidated joint ventures. In addition, we have an ownership interest in 10,045 completed or to-be-completed apartment homes through unconsolidated joint ventures or partnerships, including 5,618 apartment homes owned by entities in which we hold preferred equity investments. At December 31, 2023, the Company was developing two wholly-owned communities totaling 415 homes, of which 56 have been completed.

UDR has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, which we refer to in this Report as the “Code.” To continue to qualify as a REIT, we must continue to meet certain tests which, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets, and that we distribute at least 90% of our REIT taxable income (other than our net capital gains) to our stockholders annually. As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on our net income to the extent we distribute such net income to our stockholders annually. In 2023, we declared total distributions of $1.68 per common share and paid dividends of $1.64 per common share.

UDR was formed in 1972 as a Virginia corporation. In June 2003, we changed our state of incorporation from Virginia to Maryland. Our corporate offices are located at 1745 Shea Center Drive, Suite 200, Highlands Ranch, Colorado and our telephone number is (720) 283-6120. Our website is www.udr.com. The information contained on our website, including any information referred to in this Report as being available on our website, is not a part of or incorporated into this Report.

As of December 31, 2023, there were 189.9 million units in the Operating Partnership (“OP Units”) outstanding, of which 176.4 million OP Units (including 0.1 million of general partnership units), or 92.9%, were owned by UDR and 13.5 million OP Units, or 7.1%, were owned by outside limited partners. As of December 31, 2023, there were 32.4 million units in the DownREIT Partnership (“DownREIT Units”) outstanding, of which 21.4 million, or 66.0%, were owned by UDR and its subsidiaries and 11.0 million, or 34.0%, were owned by outside limited partners. The consolidated financial statements of UDR include the noncontrolling interests of the unitholders in the Operating Partnership and DownREIT Partnership.

Human Capital Management

As of December 31, 2023, our team at UDR comprises 1,397 full-time associates and 13 part-time associates, all of whom are dedicated to the success of our organization. Within this workforce, 991 associates are focused on roles directly associated with our communities, while the remaining associates contribute to various corporate functions. Our commitment to social responsibility extends to the entire employee lifecycle, encompassing recruitment, onboarding, development, engagement, and retention. Our overarching objective is to enhance the associate experience, foster diversity, and maintain a motivated workforce that fuels our growth and talent retention. This dedication to our UDR culture and values directly influences improved engagement, productivity, and the overall success of our organization.

Our UDR culture is defined by choice, transparency, and trust, empowering our associates to make decisions that align with their individual interests and benefit the Company as a whole. By prioritizing and enhancing the associate experience, we hope to enhance engagement levels, leading to increased customer satisfaction, higher employee 4

Table of Contents retention, and superior results. We report to our Board of Directors at least annually with respect to our human capital initiatives, including evaluations and analyses.

Associate Compensation

Attracting, nurturing, and retaining top-tier, diverse talent across our organization is essential to our long-term success. An integral part of this process is our commitment to fair and attractive compensation practices. We continue to utilize our compensation market data tool that enables us to access near real-time market insights. This tool has been helpful in helping us to make informed decisions and adjust our salary ranges accordingly, helping us to remain competitive and attract and retain top talent. By staying up-to-date with the latest trends in the job market, we seek to provide fair and competitive compensation packages to our associates. We also conduct annual assessments of pay equity across various dimensions, such as gender, age, and ethnicity, for each job title. Our compensation programs are designed to include performance-driven bonuses. These metrics are presented annually to our executive leadership and Board of Directors for oversight purposes.

Associate Growth and Development

We firmly believe that frequent training is essential for associate job satisfaction, effectiveness, career progression, and retention. New associates participate in a comprehensive two-day onboarding process that covers our culture, values, mission, and administrative procedures. We offer a wide range of training opportunities tailored to individual needs.

In addition to mandatory regulatory training (e.g., harassment, cybersecurity, fair housing), associates can opt to receive management development training through programs like the ULEAD and the Level Up! Career Mobility Programs. These initiatives equip our associates with valuable skills for career advancement. In total, over 6,000 courses are available to our associates, spanning topics such as leasing skills, property maintenance, customer service, project management, and system applications. In 2023, our associates collectively invested 13,924 hours in training, averaging 10 hours per full time associate. We also implemented improved controls around timely completion of required courses. By the end of 2023, 95% of associates had completed annual technology IT security training, while 95% had completed fair housing, harassment, diversity and inclusion, and business ethics training.

Certifications play a crucial role in career progression in the apartment industry. We actively encourage our associates to pursue professional certifications that align with their interests and benefit the Company. These certifications range from master's degree programs to certified property manager programs to technical licenses. We offer partial tuition reimbursement to support associates in attaining these certifications. Each UDR associate participates in an annual performance review with their direct supervisor, providing feedback on career development and engagement levels.

Additionally, in 2023, the Company hired a Vice President of Organizational Development and Succession Planning. Organizational development and succession planning are critical components of the Company's long-term strategy as they help UDR to have the right talent in the right positions to drive success and growth.

Diversity and Inclusion

We prioritize respect, fairness, and the promotion of diverse perspectives, which contribute to our Company's growth and success. Our commitment extends to fostering a diverse and inclusive workplace environment that facilitates the development and advancement of all associates.

As of December 31, 2023, our workforce is comprised of 60% male and 40% female associates, with an ethnic composition of 53% White, 26% Hispanic/Latino, 13% Black, 2% Asian, and 6% Other. Our management team (including resident services managers and more senior job classifications) reflects a gender balance of 57% male and 43% female, with an ethnic breakdown of 61% White and 39% non-White. Over the three-year period ending December 31, 2023, 520 promotions occurred, with 48% of those promoted to resident services manager, director, or more senior job classifications being female and 26% non-White.

We provide resources, webinars, trainings, workshops, and tools to educate our associates on DEI-related topics. Our commitment to promoting diversity and inclusion remains as we strive to create a healthy and diverse work environment and attract candidates from all backgrounds, ethnicities, and genders. 5

Associate Engagement and Outreach

Throughout 2023, we placed greater emphasis on increasing associate engagement and focused efforts on achieving this goal.  We implemented a quarterly pulse survey program and several measures aimed at improving communication, making data-driven decisions, and promoting collaboration between our operations and corporate teams. Centralizing information, creating an HR Monthly Newsletter, and initiating internal publications and recognition programs for associates were among the initiatives we undertook to facilitate better communication and foster a sense of community.

The quarterly pulse surveys we implemented in 2023 give us valuable insights into associate engagement, views on UDR culture, and work-life balance, among other key performance indicators. We find these surveys to be incredibly helpful and plan to continue conducting them to receive ongoing feedback.

We believe that our associates should be active in their communities, and we support their efforts. In 2023, UDR provided 1,041 hours of paid time off to associates for volunteer work with over 20 local organizations. We also organized food, clothing, and blood drives, as well as initiatives to promote non-profit organizations and causes, fostering a culture of giving back.

Employee Health, Wellness and Benefits

The health, wellness, and safety of our associates are paramount to UDR. We maintain an inclusive culture by prioritizing the well-being of our associates. Our monthly Wellness Newsletter covers a range of topics, including preventative care, fitness, mental health, and healthy eating habits.

In 2023, we reduced the benefits waiting period from two months to one month. In addition, we enhanced our behavioral health support mobile application, providing associates with 24/7 access to a care team of coaches and mental health professionals via text-based chats and self-guided activities at no additional cost to associates. This program was also expanded in 2023 to provide support to teen-age children for parents with teen-aged children. Finally, a new associate resource program was introduced, providing our associates with a comprehensive set of tools to assist them in every aspect of their life. This resource provides professional counseling and expert referrals for a wide array of personal and work-related concerns.

Our commitment to associate benefits is underscored by a third-party benefits survey, conducted in 2023, where 77% of respondents believed that UDR offered benefits meeting their needs. Utilizing feedback from this survey and our engagement survey, we enhanced the Lifestyle Spending Account. The Lifestyle Spending Account provides flexibility by allowing associates to allocate $1,000 annually to various health, wellness, and lifestyle categories. Furthermore, we implemented a 401(k) auto-enrollment for new hires at 3% of their salary that started in January 2024. We also provide a comprehensive set of employee benefits, including health, dental, and vision insurance coverage for all associates.

Reporting Segments

We report in two segments: Same-Store Communities and Non-Mature Communities/Other.

Our Same-Store Communities segment represents those communities acquired, developed, and stabilized prior to January 1, 2022, and held as of December 31, 2023. These communities were owned and had stabilized occupancy and operating expenses as of the beginning of the prior year, there is no plan to conduct substantial redevelopment activities, and the communities are not classified as held for disposition at year end. A community is considered to have stabilized occupancy once it achieves 90% occupancy for at least three consecutive months.

Our Non-Mature Communities/Other segment represents those communities that do not meet the criteria to be included in Same-Store Communities, including, but not limited to, recently acquired, developed and redeveloped communities, and the non-apartment components of mixed use properties. For additional information regarding our operating segments, see Note 16, Reportable Segments, in the Notes to the UDR Consolidated Financial Statements included in this Report. 6

Table of Contents Business Objectives

Our principal business objective is to maximize the economic returns of our apartment communities in a sustainable manner to provide our stockholders with the greatest possible total return and value. To achieve this objective, we intend to continue to pursue the following goals and strategies:

own and operate a diversified portfolio of apartments in targeted markets in the United States, which are characterized by strong total income growth, high working age population growth, relatively robust rental versus single-family home affordability and favorable demand/supply ratio for multifamily housing, thus enhancing stability and predictability of returns to our stockholders;
manage real estate cycles by taking an opportunistic approach to buying, selling, renovating, redeveloping, and developing apartment communities;
--- ---
empower site associates to manage our communities efficiently and effectively;
--- ---
measure and reward associates based on specific performance targets; and
--- ---
manage our capital structure with the intent of lowering our relative cost of capital to enhance profitability and predictability of liquidity, earnings and dividends.
--- ---

2023 Highlights

Commitment to Shareholders

● In July 2023, the Company marked its 51^st^ year as a REIT and, in October 2023, paid its 204^th^ consecutive quarterly dividend. The Company’s annualized declared 2023 dividend of $1.68 represented a 10.5% increase over the previous year.

Property Operations

Net income attributable to common stockholders was $439.5 million as compared to $82.5 million in the prior year. The increase was primarily driven by higher gains from dispositions of real estate, higher total net operating income (“NOI”), and higher interest income and other income/(expense) primarily due to realized and unrealized gains from our direct investment in SmartRent, Inc. (“SmartRent”) and higher interest income driven by higher notes receivable balances. These were partially offset by higher depreciation expense primarily due to communities acquired and completion of developments in 2023 and 2022, and higher interest expense primarily due to higher average interest rates and higher overall debt balances.
Total revenues increased 7.3% over the prior year primarily due to overall market rent growth and communities acquired and completion of developments during 2023 and 2022, partially offset by dispositions of real estate in 2023.
--- ---
We achieved Same-Store revenue growth of 5.6% and Same-Store NOI growth of 6.0%.
--- ---

Investing and Developments

● We acquired six operating communities located in Dallas, Texas, and Austin, Texas, for approximately $354.6 million.

We contributed four wholly-owned operating communities to a newly formed joint venture in exchange for a 51.0% interest in the venture. We received approximately $247.9 million in cash proceeds from our joint venture partner at formation and we recognized gains of $325.9 million from the partial sale of the operating communities. The joint venture also acquired an operating community located in Norwood, Massachusetts, from a third party for $114.3 million.

● We completed the development of one community located in Washington, D.C., with a total of 300 apartment homes. 7

Table of Contents ● We recognized a gain of $25.3 million from the sale of an operating community located in Hillsboro, Oregon.

● We funded an additional $21.8 million to two of our Developer Capital Program preferred equity investments.

● We funded an additional $85.3 million to five of our notes receivable investments.

Balance Sheet

● We amended our Working Capital Credit Facility to extend the maturity date from January 12, 2024 to January 12, 2025, plus a one-year extension option.

● We repurchased 0.6 million shares of common stock for approximately $25.0 million.

ESG Report

We published our 2023 ESG Report on our website, which discloses our environmental and social initiatives, programs, and performance. The report’s ESG disclosures were, to the extent applicable, prepared in accordance with the Global Reporting Initiative (GRI) Standards (core), the Sustainability Accounting Standards Board (SASB) standards, and the Task Force for Climate-related Financial Disclosure (TCFD) framework.

Refer to Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, for further information on the Company’s activities in 2023.

Our Strategic Vision

Our strategic vision is to be the multifamily public REIT of choice for investors. We intend to realize this vision by executing on our strategic objectives, which are:

1. Maintaining a Diversified Portfolio and Allocating Capital to Accretive Investment Opportunities
2. Maintaining a Strong Balance Sheet
--- ---
3. Consistently Driving Operating Excellence
--- ---
4. Advancing a Strong Corporate Culture and Striving for High Resident Satisfaction
--- ---

Maintaining a Diversified Portfolio and Allocating Capital to Accretive Investment Opportunities

We believe greater portfolio diversification, as defined by geographic concentration, location within a market (i.e., urban or suburban) and property quality (i.e., A or B), reduces the volatility of our same-store growth throughout the real estate cycle, appeals to a wider renter and investor audience, lessens the market risk associated with owning a homogenous portfolio, and provides more opportunities for accretive external growth when appropriate. Diversified characteristics of our portfolio include:

our consolidated apartment portfolio includes 168 communities located in 21 markets throughout the U.S., including both coastal and sunbelt locations;
our communities that are located proximate to each other within a market provide enhanced economics; and
--- ---
our mix of urban/suburban communities is approximately 31%/69% and our mix of A/B quality properties is approximately 44%/56%.
--- ---

We are focused on increasing our presence in markets with favorable job formation and income growth, high propensity to rent, strong relative affordability for rental versus homeownership, and a favorable demand/supply ratio for multifamily housing. Portfolio investment decisions consider internal analyses and third-party research.

Acquisitions and Dispositions

When evaluating potential acquisitions, we consider a wide variety of factors, including:

high working age population growth, relatively robust rental versus single-family home affordability, measured long-term new supply growth, overall potential for strong total income growth;

Table of Contents Development Activities

Our objective in developing a community is to create value while improving the quality of our portfolio. How demographic trends, economic drivers, and multifamily fundamentals and valuations have trended over the long-term and our portfolio strategy generally govern our review process on where and when to allocate development capital. At December 31, 2023, the Company was developing two wholly-owned communities located in Addison, Texas and Tampa, Florida, totaling 415 homes, of which 56 have been completed, with a budget of $187.5 million, in which we have an investment of $160.4 million. The communities are estimated to be completed in the second quarter of 2024.

Redevelopment Activities

Our objective in redeveloping a community is twofold: we aim to grow rental rates while also producing a higher yielding and more valuable asset through asset quality improvement. During the year ended December 31, 2023, we incurred $123.3 million in major renovations, which included major structural changes and/or architectural revisions to existing buildings. As of December 31, 2023, the Company had no communities at which it was conducting substantial redevelopment activities.

Joint Venture and Partnership Activities

We have entered into, and may continue in the future to enter into, joint ventures (including limited liability companies or partnerships) through which we own an indirect economic interest of less than 100% of the community or communities owned directly by such joint ventures. Our decision to either hold an apartment community in fee simple or have an indirect interest in the community through a joint venture is based on a variety of factors and considerations, including: (i) the economic and tax terms required by the seller of land or a community; (ii) our desire to diversify our portfolio of communities by market, submarket and product type; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) our projections, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture vehicle is used. Each joint venture agreement is individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture agreement.

Maintaining a Strong Balance Sheet

We maintain a capital structure that we believe allows us to proactively source potential investment opportunities in the marketplace. We have structured our debt maturity schedule to be able to opportunistically access both secured and unsecured debt markets when appropriate.

As part of our plan to finance our activities, we utilize proceeds from debt and equity offerings and refinancings to extend maturities, pay down existing debt, fund development and redevelopment activities, and acquire apartment communities.

Consistently Driving Operational Excellence

Investment in new technologies continues to drive operating efficiencies in our business and helps us to better meet the changing needs of our business and our residents. Our residents can conduct business with us 24 hours a day, 7 days a week, including completing online leasing applications and renewals and submitting maintenance or other requests throughout our portfolio using our web-based resident internet portal or, increasingly, a smart-device application.

As a result of transforming our operations through technology, residents’ satisfaction has improved, and our operating teams have become more efficient. Web-based technologies have also resulted in declining marketing and advertising costs, improved cash management, and better pricing management of our available apartment homes.

Table of Contents Competitive Conditions

Competition for new residents is generally intense across our markets. Some competing communities offer amenities that our communities do not have. Competing communities can use rental concessions or lower rents to obtain temporary competitive advantages. Also, some competing communities are larger or newer than our communities. The competitive position of each community is different depending upon many factors, including sub-market supply and demand. In addition, other real estate investors compete with us to acquire existing properties, redevelop existing properties, and to develop new properties. These competitors include insurance companies, pension and investment funds, public and private real estate companies, investment companies and other public and private apartment REITs, some of which may have greater resources, or lower capital costs, than we do.

We believe that, in general, we are well-positioned to compete effectively for residents and investments. We believe our competitive advantages include:

a fully integrated organization with property management, development, redevelopment, acquisition, marketing, sales and financing expertise;
scalable operating and support systems, which include automated systems to meet the changing needs of our residents and to effectively focus on our internet-based marketing efforts;
--- ---
access to diversified sources of capital;
--- ---
geographic diversification with a presence in 21 markets across the country; and
--- ---
significant presence in many of our major markets that allows us to be a local operating expert.
--- ---

Moving forward, we will continue to improve lease management, improve expense control, increase resident retention efforts and align employee incentive plans with metrics that impact our bottom-line performance. We believe this plan of operation, coupled with the portfolio’s strengths in targeting renters across a geographically diverse platform, should position us for continued operational upside.

Communities

At December 31, 2023, our consolidated real estate portfolio included 168 communities with a total of 55,550 completed apartment homes. The overall quality of our portfolio generally enables us to raise rents and to attract residents with higher levels of disposable income who are more likely to absorb such rents.

At December 31, 2023, the Company was developing two wholly-owned communities located in Addison, Texas, and Tampa, Florida, totaling 415 homes, of which 56 have been completed, with a budget of $187.5 million, in which we have an investment of $160.4 million. The communities are estimated to be completed in the second quarter of 2024.

At December 31, 2023, the Company had no communities at which it was conducting substantial redevelopment activities.

Same-Store Community Comparison

We believe that one pertinent quantitative measurement of the performance of our portfolio is tracking the results of our Same-Store Communities’ NOI, which is total rental revenue, less rental and other operating expenses excluding property management. Our Same-Store Community population is comprised of operating communities which we own and have stabilized occupancy, revenues and expenses as of the beginning of the prior year.

Net income attributable to common stockholders was $439.5 million as compared to $82.5 million in the prior year. The increase was primarily driven by higher gains from dispositions of real estate, higher total NOI, and higher interest income and other income/(expense) primarily due to realized and unrealized gains from our direct investment in SmartRent, Inc. (“SmartRent”) and higher interest income driven by higher notes receivable balances, partially offset by higher depreciation expense due to communities acquired and completion of developments in 2023 and 2022, and higher interest expense primarily due to higher average interest rates and higher overall debt balances. 11

Table of Contents For the year ended December 31, 2023, our Same-Store NOI increased by $58.8 million compared to the prior year. Our Same-Store Community properties provided 93.1% of our total NOI for the year ended December 31, 2023. The increase in NOI for the 51,368 Same-Store apartment homes, or 92.5% of our portfolio, was primarily driven by an increase in market rental rates, an increase in reimbursement, ancillary and fee income and a decrease in insurance expense, partially offset by the impact from rent concessions, higher bad debt, higher vacancy loss, higher repair and maintenance expense, higher utility expense and higher real estate tax expense.

Revenue growth in 2024 may be impacted by adverse developments affecting the general economy, inclusive of economic conditions as a result of a recession, reduced occupancy rates, increased rental concessions, new supply, increased bad debt and other factors which may adversely impact our ability to increase rents.

Tax Matters

UDR has elected to be taxed as a REIT under the Code. To continue to qualify as a REIT, UDR must continue to meet certain tests that, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets, and that we distribute at least 90% of our REIT taxable income (other than net capital gains) to our stockholders annually. Provided we maintain our qualification as a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on our net income to the extent such net income is distributed to our stockholders annually. Even if we continue to qualify as a REIT, we will continue to be subject to certain federal, state and local taxes on our income and property.

We may utilize our taxable REIT subsidiary (“TRS”) to engage in activities that REITs may be prohibited from performing, including the provision of management and other services to third parties and the conduct of certain nonqualifying real estate transactions. Our TRS generally is taxable as a regular corporation, and therefore, subject to federal, state and local income taxes.

Inflation

Inflation primarily impacts our results of operations as a result of wage pressures and increases in utilities and repair and maintenance costs. In addition, inflation could also impact our general and administrative expenses, the interest on our debt if variable or refinanced in a high-inflationary environment, our cost of capital, and our cost of development, redevelopment, maintenance or other operating activities. However, the majority of our apartment leases have initial terms of 12 months or less, which in an inflationary environment, and absent other factors such as increased supply, generally enables us to compensate for inflationary effects by increasing rents on our apartment homes. Although an extreme or sustained escalation in costs could have a negative impact on our residents and their ability to absorb rent increases, we do not believe this had a material impact on our results for the year ended December 31, 2023.

Environmental Matters

Various environmental laws govern certain aspects of the ongoing operation of our communities. Such environmental laws include those regulating the existence of asbestos-containing materials in buildings, management of surfaces with lead-based paint (and notices to residents about the lead-based paint), use of active underground petroleum storage tanks, and waste-management activities. The failure to comply with such requirements could subject us to a government enforcement action and/or claims for damages by a private party.

To date, compliance with federal, state and local environmental protection regulations has not had a material effect on our capital expenditures, earnings or competitive position. We have a property management plan for hazardous materials. As part of the plan, Phase I environmental site investigations and reports have been completed for each property we acquire. In addition, all proposed acquisitions are inspected prior to acquisition. The inspections are conducted by qualified environmental consultants, and we review the issued report prior to the purchase or development of any property. Nevertheless, it is possible that the environmental assessments will not reveal all environmental liabilities, or that some material environmental liabilities exist of which we are unaware. In some cases, we have abandoned otherwise economically attractive acquisitions because the costs of removal or control of hazardous materials have been prohibitive or we have been unwilling to accept the potential risks involved. We do not believe we will be required to engage in any large-scale abatement at any of our properties. We believe that through professional environmental inspections and testing for asbestos, lead paint and other hazardous materials, coupled with a relatively conservative posture toward accepting known environmental risk, we can minimize our exposure to potential liability associated with environmental hazards. 12

Table of Contents Federal legislation requires owners and landlords of residential housing constructed prior to 1978 to disclose to potential residents or purchasers of the communities any known lead paint hazards and imposes treble damages for failure to provide such notification. In addition, lead based paint in any of the communities may result in lead poisoning in children residing in that community if chips or particles of such lead based paint are ingested, and we may be held liable under state laws for any such injuries caused by ingestion of lead based paint by children living at the communities.

We are unaware of any environmental hazards at any of our properties that individually or in the aggregate may have a material adverse impact on our operations or financial position. We have not been notified by any governmental authority, and we are not otherwise aware, of any material non-compliance, liability, or claim relating to environmental liabilities in connection with any of our properties. We do not believe that the cost of continued compliance with applicable environmental laws and regulations will have a material adverse effect on us or our financial condition or results of operations. Future environmental laws, regulations, or ordinances, however, may require additional remediation of existing conditions that are not currently actionable. Also, if more stringent requirements are imposed on us in the future, the costs of compliance could have a material adverse effect on our results of operations and our financial condition.

Insurance

We carry comprehensive general liability coverage on our communities, with limits of liability customary within the multi-family apartment industry to insure against liability claims and related defense costs. We are also insured, with limits of liability customary within the multi-family apartment industry, against the risk of direct physical damage on a replacement cost basis, including loss of rental income during the reconstruction period.

Item 1A. RISK FACTORS

There are many factors that affect the business and the results of operations of the Company, some of which are beyond its control. The following is a description of important factors that may cause the Company’s actual results in future periods to differ materially from those currently expected or discussed in forward-looking statements set forth in this Report relating to our financial results, operations and business prospects. Forward-looking statements and such risks, uncertainties and other factors speak only as of the date of this Report, and we expressly disclaim any obligation or undertaking to update or revise any forward-looking statement contained herein, to reflect any change in our expectations with regard thereto, or any other change in events, conditions or circumstances on which any such statement is based, except to the extent otherwise required by law.

Risks Related to Our Real Estate Investments and Our Operations

Unfavorable Apartment Market and Economic Conditions Could Adversely Affect Occupancy Levels, Rental Revenues and the Value of Our Real Estate Assets. Unfavorable market conditions in the areas in which we operate or unfavorable economic conditions generally, may significantly affect our occupancy levels, our rental rates and collections, the value of our properties and our ability to acquire or dispose of apartment communities on economically favorable terms. Our ability to lease our properties at favorable rates is adversely affected by the increase in supply in the multifamily and other rental markets and is dependent upon the overall level in the economy, which is adversely affected by, among other things, job losses and unemployment levels, recession, debt levels, housing markets, stock market volatility and uncertainty about the future. Some of our major expenses generally do not decline when related rents decline. We would expect that declines in our occupancy levels and rental revenues would cause us to have less cash available to pay our indebtedness and to distribute to our stockholders, which could adversely affect our financial condition or the market value of our securities. Factors that have in the past and may in the future affect our occupancy levels, our rental revenues, and/or the value of our properties include the following, among others:

downturns in global, national, regional and local economic conditions, particularly increases in unemployment;
declines in mortgage interest rates, making alternative housing options more affordable;
--- ---
government or builder incentives with respect to home ownership, making alternative housing options more attractive;
--- ---
local real estate market conditions, including oversupply of, or reduced demand for, apartment homes;
--- ---
declines in the financial condition of our tenants, which may make it more difficult for us to collect rents from some tenants;
--- ---
changes in market rental rates;
--- ---
our ability to renew leases or re-lease space on favorable terms;
--- ---
the timing and costs associated with property improvements, repairs or renovations;
--- ---
changes in household formation; and
--- ---
rent control or stabilization laws, or other laws regulating or impacting rental housing, which could prevent us from raising rents to offset increases in operating costs or otherwise impact us.
--- ---

The Geographic Concentration of Our Communities in Certain Markets Could Have an Adverse Effect on Our Operations if a Particular Market is Adversely Impacted by Economic or Other Conditions. For the year ended December 31, 2023, approximately 73.3% of our total NOI was generated from communities located in Metropolitan D.C. (14.9%), Boston, MA (11.3%), Orange County, CA (10.9%), Dallas, TX (8.6%),the San Francisco Bay Area, CA (8.2%), New York, NY (7.7%), Seattle, WA (6.3%) and Tampa, FL (5.4%). As a result, if any one or more of these markets is adversely impacted by regional or local economic conditions or real estate market conditions, such conditions may have a greater adverse impact on our results of operations than if our portfolio was more geographically diverse. In addition, if one or more of these markets is adversely affected by changes in regional or local regulations, including those related to rent control or stabilization, such regulations may have a greater adverse impact on our results of operations than if our portfolio was more geographically diverse. 14

Table of Contents We May Be Unable to Renew Leases or Relet Apartment Units as Leases Expire, or the Terms of Renewals or New Leases May Be Less Favorable Than Current Leases. When our residents decide to leave our apartments, whether because their leases are not renewed or they leave prior to their lease expiration date, we may not be able to relet their apartment units. Even if leases are renewed or we can relet the apartment units, the terms of renewal or reletting may be less favorable than current lease terms. Furthermore, because the majority of our apartment leases have initial terms of 12 months or less, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms. If we are unable to promptly renew the leases or relet the apartment units, or if the rental rates upon renewal or reletting are lower than expected rates, then our results of operations and financial condition may be adversely affected. If residents do not experience increases in their income or if they experience decreases in their income or job losses, we may be unable to increase or maintain rent and/or delinquencies may increase.

We Face Certain Risks Related to Our Retail and Commercial Space. Certain of our properties include retail or commercial space that we lease to third parties. The long-term nature of our retail and commercial leases (generally five to ten years with market-based or fixed-price renewal options) and the characteristics of many of our tenants (generally small and/or local businesses) may subject us to certain risks. The longer-term leases could result in below market lease rates over time, particularly in an inflationary environment. We may require guarantees and other credit support which may prove to be inadequate or uncollectable, and the failure rate of small and/or local businesses may be higher than average. We may not be able to lease new space for rents that are consistent with our projections or for market rates. Also, when leases for our retail or commercial space terminate either at the end of the lease or because a tenant leaves early, the space may not be relet or the terms of reletting, including the cost of allowances and concessions to tenants, may be less favorable than the prior lease terms or we may incur additional expenses related to modifications of the spaces in order to satisfy new tenants. Our properties compete with other properties with retail or commercial space. The presence of competitive alternatives may adversely affect our ability to lease space and the level of rents we can obtain. Our retail or commercial tenants have experienced in the past, and may experience in the future, financial distress or bankruptcy, or may fail to comply with their contractual obligations, seek concessions in order to continue operations, or cease their operations, which could adversely impact our results of operations and financial condition.

We Face Risks Related to Inflation/Deflation. Substantial inflationary or deflationary pressures could have a negative effect on rental rates and property operating expenses. The U.S. economy has recently experienced high rates of inflation, which has increased our operating expenses due to higher third party vendor costs and increased our interest expense due to higher interest rates on our variable rate debt. Although the short-term nature of our apartment leases may, absent other factors, enable us to compensate for inflationary effects by increasing rents on our apartment homes, an extreme or sustained escalation in costs could have a negative impact on our residents and their ability to absorb rent increases. The general risk of inflation is that interest on our debt, general and administrative expenses, materials costs, labor costs, and other expenses increase at a rate faster than increases in our rental rates, which could adversely affect our financial condition or results of operations.

We Are Subject to Certain Risks Associated with Selling Apartment Communities, Which Could Limit Our Operational and Financial Flexibility. We periodically dispose of apartment communities that no longer meet our strategic objectives, but adverse market conditions may make it difficult to sell apartment communities we own. We cannot predict whether we will be able to sell any property for the price or on the terms we set, or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser or to close the sale of a property. Furthermore, we may be required to expend funds to correct defects or to make improvements before a property can be sold or the purchase price may be reduced to cover any cost of correcting defects or making improvements. These conditions may limit our ability to dispose of properties and to change our portfolio in order to meet our strategic objectives, which could in turn adversely affect our financial condition, results of operations or our ability to fund other activities in which we may want to engage such as the purchase of properties, development or redevelopment, or funding the Developer Capital Program. We are also subject to the following risks in connection with sales of our apartment communities, among others:

a significant portion of the proceeds from some property sales may be held by intermediaries in order for such sales to qualify as like-kind exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended, or the “Code,” so that any related capital gain can be deferred for federal income tax purposes. As a result, we may not have immediate access to all of the cash proceeds generated from our property sales; and
federal tax laws limit our ability to profit on the sale of communities or interests in communities that we have owned for less than two years, and this limitation may prevent us from selling communities when market conditions are favorable.

15

Table of Contents Competition Could Limit Our Ability to Lease Apartment Homes or Increase or Maintain Rents. Our apartment communities compete with numerous housing alternatives in attracting residents, including other apartment communities, condominiums and single-family rental homes, as well as owner occupied single- and multi-family homes. Competitive housing in a particular area, including new supply, could adversely affect our ability to lease apartment homes and increase or maintain rents, which could materially and adversely affect our results of operations and financial condition.

We May Not Realize the Anticipated Benefits of Past or Future Acquisitions, and the Failure to Integrate Acquired Communities and New Personnel Successfully Could Create Inefficiencies. We have acquired in the past, and if presented with attractive opportunities we intend to acquire in the future, apartment communities that meet our investment criteria. Our acquisition activities and their success are subject to the following risks, among others:

we may be unable to obtain financing for acquisitions on favorable terms, or at all, which could cause us to delay or even abandon potential acquisitions;
even if we are able to finance an acquisition, cash flow from the acquisition may be insufficient to meet our required principal and interest payments on the debt used to finance the acquisition;
--- ---
even if we enter into an acquisition agreement for an apartment community, we may not complete the acquisition for a variety of reasons after incurring certain acquisition-related costs;
--- ---
we may incur significant costs and divert management attention in connection with the evaluation and negotiation of potential acquisitions, including potential acquisitions that we subsequently do not complete;
--- ---
when we acquire an apartment community, we may invest additional amounts in it with the intention of increasing profitability, and these additional investments may not produce the anticipated improvements in profitability;
--- ---
the expected occupancy rates, rental rates and expenses may differ from actual results; and
--- ---
we may be unable to quickly and efficiently integrate acquired apartment communities and new personnel into our existing operations, and the failure to successfully integrate such apartment communities or personnel will result in inefficiencies that could materially and adversely affect our expected return on our investments and our overall profitability.
--- ---

Competition Could Adversely Affect Our Ability to Acquire Properties. In the past, other real estate investors, including insurance companies, pension and investment funds, developer partnerships, investment companies and other public and private apartment REITs, have competed with us to acquire existing properties and to develop new properties, and such competition in the future may limit attractive investment opportunities, which could adversely affect our ability to grow or acquire properties profitably or with attractive returns.

Development and Construction Risks Could Impact Our Profitability. In the past we have selectively pursued the development and construction of apartment communities, and we intend to do so in the future as appropriate opportunities arise. Development activities have been, and in the future may be, conducted through wholly-owned affiliated companies or through joint ventures with unaffiliated parties. Our development and construction activities are subject to the following risks, among others:

we may be unable to obtain construction financing for development activities on favorable terms, or at all, which could cause us to delay or even abandon potential developments;
we may experience supply chain constraints, which could result in increased development costs or delay initial occupancy dates for all or a portion of a development community;
--- ---
we may be unable to obtain, or face delays in obtaining, necessary zoning, land-use, building, occupancy and other required governmental or quasi-governmental permits and authorizations, which could result in increased development costs, delay initial occupancy dates for all or a portion of a development community, and require us to abandon our activities entirely with respect to a project for which we are unable to obtain permits or authorizations;
--- ---
costs may be higher or yields may be less than anticipated as a result of delays in completing projects, costs that exceed budget, defaults by our counterparties, and/or higher than expected concessions for lease-up and lower rents than expected;
--- ---

16

Table of Contents

we may abandon development opportunities that we have already begun to explore, and we may fail to recover expenses already incurred in connection with exploring such development opportunities;
we may be unable to complete construction and lease-up of a community on schedule, or we may incur development or construction costs that exceed our original estimates, and we may be unable to charge rents that would compensate for any increase in such costs;
--- ---
occupancy rates, rents and concessions at a newly developed community may fluctuate depending on a number of factors, including market and economic conditions, preventing us from meeting our expected return on our investment and our overall profitability goals; and
--- ---
when we sell communities or properties that we developed or renovated to third parties, we may be subject to warranty or construction defect claims that are uninsured or exceed the limits of our insurance.

An Epidemic, Pandemic or Other Health Crisis, and Measures Intended to Prevent the Spread of Such an Event, Could Have a Material Adverse Effect on our Business, Results of Operations, Cash Flows and Financial Condition. We face risks related to an epidemic, pandemic or other health crisis, which have impacted, and in the future could impact, the markets in which we operate and could have a material adverse effect on our business, results of operations, cash flows and financial condition. The impact of an epidemic, pandemic or other health crisis, and measures to prevent the spread of such an event, could materially and adversely affect our business in a number of ways. Our rental revenue and operating results depend significantly on the occupancy levels at our properties and the ability of our residents and retail and commercial tenants to meet their rent obligations to us, which have been in certain cases, and could in the future be, adversely affected by, among other things, job losses, furloughs, store closures, lower incomes, uncertainty about the future as a result of an epidemic, pandemic or other health crisis and related governmental actions, including eviction moratoriums, shelter-in-place orders, prohibitions or limits on charging certain fees, and limitations on collections and or rent increases, which have affected, and, if such restrictions are not lifted, or are reinstated, or new restrictions imposed, may continue to **** affect our ability to collect rent or enforce legal or contractual remedies for the failure to pay rent, which have negatively impacted, and may continue to negatively impact, our ability to remove residents or retail and commercial tenants who are not paying rent and our ability to rent their units or other space to new residents or retail and commercial tenants, respectively. In addition, the federal government has in the past allocated, and federal, state or local governments may in the future allocate, funds to rent relief programs. In certain locations, the funds available may not be sufficient to pay all past due rent and reallocation of such funds may result in markets in which we operate not having access to the funds anticipated. Further, certain of our residents with past due rent have not qualified, and may not in the future qualify, to participate in such programs. In addition, some of such programs have required, and programs in the future may require, the forgiveness of a portion of the past due rent or agreeing to other limitations that may adversely affect our business in order to participate or may only provide funds to pay a portion of the past due rent. In addition, while certain locations have adopted programs that may reimburse past due rent owed by residents who have left a community, such programs have only been adopted in a minority of our markets. It is uncertain how any rent relief programs will impact our business in the future.

State, local, and federal governments also have increased, and may in the future increase, property taxes or other taxes or fees, or may enact new taxes or fees, in order to increase revenue in connection with an epidemic, pandemic or other health crisis, which has in the past increased, and may in the future increase, our expenses. Our development and construction projects, including those in our Developer Capital Program, also have been and could in the future be adversely affected by factors related to an epidemic, pandemic or other health crisis. An epidemic, pandemic or other health crisis, or related impacts thereof also could adversely affect the businesses and financial conditions of our counterparties, including our joint venture partners, participants in the Developer Capital Program, and general contractors and their subcontractors, and their ability to satisfy their obligations to us and to complete transactions or projects with us as intended.

Bankruptcy or Defaults of Our Counterparties Could Adversely Affect Our Performance. We have relationships with and we execute transactions with or receive services from many counterparties, such as general contractors engaged in connection with our development activities, borrowers, or joint venture partners, among others. As a result, bankruptcies or defaults by these counterparties or their subcontractors have resulted in, and in the future could result in, services not being provided as expected, projects not being completed on time, on budget, or at all, or contractual obligations to us not being satisfied. Further, volatility in the financial markets and economic weakness could affect the counterparties’ ability to complete transactions with us as intended. Either circumstance could result in disruptions to our operations that may adversely affect our financial condition and results of operations. 17

Table of Contents Property Ownership Through Partnerships and Joint Ventures May Limit Our Ability to Act Exclusively in Our Interest. We have in the past and may in the future develop and/or acquire properties through partnerships and joint ventures, including those in which we own a preferred interest, with other persons or entities when we believe circumstances warrant the use of such structures. As of December 31, 2023, we had active unconsolidated joint ventures and partnerships, including our preferred equity investments, with a total equity investment of $952.9 million. We have in the past, and could in the future, become engaged in a dispute with one or more of our partners which could adversely impact us. Moreover, our partners may have business, economic or other objectives that are inconsistent with our objectives, including objectives that relate to the appropriate timing and terms of any sale or refinancing of a property. In some instances, our partners may have competing interests in our markets that could create conflicts of interest. Also, our partners have in the past failed and may in the future fail to make capital contributions when due and our partners or the project may otherwise not act or perform as expected, which may require us to contribute additional capital or take other actions that may negatively impact the project or our return. In addition, we may be responsible to our partners for indemnifiable losses. In general, we and our partners may each have the right to trigger a buy-sell or other similar arrangement, which arrangement or other factors could cause us to sell our interest, or acquire our partner’s interest or other property, at a time when we otherwise would not have initiated such a transaction and may result in the valuation of our interest in the partnership or joint venture (if we are the seller) or of the other partner’s interest in the partnership or joint venture (if we are the buyer) at levels which may not be representative of the valuation that would result from an arm’s length marketing process and could cause us to recognize unanticipated capital gains or losses or the loss of fee income.

We may also be subject to other risks in connection with partnerships or joint ventures, including (i) a deadlock if we and our partner are unable to agree upon certain major and other decisions (which could result in litigation or disposing of an asset at a time at which we otherwise would not sell the asset), (ii) limitations on our ability to liquidate our position in the partnership or joint venture without the consent of the other partner, and (iii) requirements to provide guarantees in favor of lenders with respect to the indebtedness of the joint venture.

We May Not be Permitted to Dispose of Certain Properties or Pay Down the Indebtedness Associated with Those Properties When We Might Otherwise Desire to do so Without Incurring Additional Costs. In connection with certain property acquisitions, we have agreed with the sellers that we will not dispose of the acquired properties or reduce the mortgage indebtedness on such properties for significant periods of time unless we pay certain of the resulting tax costs of the sellers or dispose of the property in a transaction in which a gain is not recognized for federal income tax purposes by such sellers, and we may enter into similar agreements in connection with future property acquisitions. These agreements could result in us retaining properties that we would otherwise sell or not paying down or refinancing indebtedness that we would otherwise pay down or refinance. However, subject to certain conditions, we retain the right to substitute other property or debt to meet these obligations to the sellers.

We Could Incur Significant Insurance Costs and Some Potential Losses May Not Be Adequately Covered by Insurance. We have a comprehensive insurance program covering our properties and operating activities with limits of liability, deductibles and self-insured retentions that we believe are comparable to similarly situated companies, including within the multifamily industry. We believe the policy specifications and insured limits of these policies are adequate and appropriate. There are, however, certain types of extraordinary losses that may not be adequately covered under our insurance program. In addition, we will sustain losses due to insurance deductibles, self-insured retention, uninsured claims or casualties, or losses in excess of applicable coverage.

If an uninsured loss or a loss in excess of insured limits occurs, we could lose all or a portion of the capital we have invested in a property, as well as the future revenue from the property. In such an event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. Material losses in excess of insurance proceeds may occur in the future. If one or more of our properties were to experience a catastrophic loss, it could seriously disrupt our operations, delay revenue and result in large expenses to repair or rebuild the property. Such events could materially and adversely affect our financial condition and results of operations.

The cost of insuring our apartment communities and our operations is a component of expense. Insurance premiums and the terms and conditions of insurance policies are subject to significant fluctuations and changes, which are generally outside of our control. We insure our properties and our operations with insurance companies that we believe have a good rating at the time our policies are put into effect. The financial condition of one or more insurance companies that insure us may be negatively impacted, which could result in their inability to pay on future insurance claims. Their inability to pay future claims may have a negative impact on our financial results. In addition, the failure, or exit or partial exit from an insurance market, of one or more insurance companies or other changes in insurance markets in general may affect our ability to obtain insurance coverage in the amounts that we seek, or at all, increase the 18

Table of Contents costs to renew or replace our insurance policies, cause us to self-insure a portion of the risk, or increase the cost of insuring properties.

Failure to Succeed in New Markets May Limit Our Growth. We have acquired in the past, and we may acquire in the future if opportunities we believe are appropriate arise, apartment communities that are outside of our existing markets. Entering into new markets may expose us to a variety of risks, and we may not be able to operate successfully in new markets. These risks include, among others:

inability to accurately evaluate local apartment market conditions and local economies;
inability to hire and retain key personnel;
--- ---
lack of familiarity with local governmental and permitting procedures; and
--- ---
inability to achieve budgeted financial results.
--- ---

Failure to Succeed with New Initiatives May Limit Our Ability to Grow NOI. We have in the past developed and may in the future develop initiatives that are intended to drive operating efficiencies and grow NOI, including smart home technologies and self-service options that are accessible to residents through smart devices or otherwise. Such initiatives in the past have involved and in the future may involve our associates having new or different responsibilities and processes. We may incur significant costs and divert resources in connection with such initiatives, and these initiatives may not perform as projected, which could adversely affect our results of operations and the market price of our common stock.

Potential Liability for Environmental Contamination Could Result in Substantial Costs. Under various federal, state and local environmental laws, as a current or former owner or operator of real estate, we could be required to investigate and remediate the effects of contamination of currently or formerly owned real estate by hazardous or toxic substances, often regardless of our knowledge of or responsibility for the contamination and solely by virtue of our current or former ownership or operation of the real estate. In addition, we could be held liable to a governmental authority or to third parties for property damage and for investigation and clean-up costs incurred in connection with the contamination or we could be required to incur additional costs to change how the property is constructed or operated due to presence of such substances. These costs could be substantial, and in many cases environmental laws create liens in favor of governmental authorities to secure their payment. The presence of such substances or a failure to properly remediate any resulting contamination could materially and adversely affect our ability to borrow against, sell or rent an affected property.

In addition, our properties are subject to various federal, state and local environmental, health and safety laws, including laws governing the management of wastes and underground and aboveground storage tanks. Noncompliance with these environmental, health and safety laws could subject us to liability. Changes in laws could increase the potential costs of compliance with environmental laws, health and safety laws or increase liability for noncompliance. This may result in significant unanticipated expenditures or may otherwise adversely affect our financial condition and results of operations.

As the owner or operator of real property, we may also incur liability based on various building conditions. For example, buildings and other structures on properties that we currently own or operate or those we acquire or operate in the future contain, may contain, or may have contained, asbestos-containing material, or ACM, or other hazardous substances. Environmental, health and safety laws require that ACM and other hazardous substances be properly managed and maintained and may impose fines or penalties on owners, operators or employers for non-compliance with those requirements.

These requirements include special precautions, such as removal, abatement or air monitoring, if ACM would be disturbed during maintenance, renovation or demolition of a building, potentially resulting in substantial costs. In addition, we may be subject to liability for personal injury or property damage sustained as a result of exposure to ACM or other hazardous substances or releases of ACM or other hazardous substances into the environment.

We cannot assure you that costs or liabilities incurred as a result of environmental or building condition issues will not adversely affect our financial condition and results of operations.

Our Properties May Contain or Develop Harmful Mold or Suffer from Other Indoor Air Quality Issues, Which Could Lead to Liability for Adverse Health Effects or Property Damage or Cost for Remediation. When excessive 19

Table of Contents moisture accumulates in buildings or on building materials, mold growth may occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can also stem from inadequate ventilation, chemical contamination from indoor or outdoor sources, and other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants can be alleged to cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly remediation program to contain or remove the mold or other airborne contaminants or to increase ventilation, which could adversely affect our results of operations and cash flows. In addition, the presence of significant mold or other airborne contaminants could expose us to liability from our tenants or others for property damage or personal injury.

Compliance or Failure to Comply with the Americans with Disabilities Act of 1990 or Other Safety Regulations and Requirements Could Result in Substantial Costs. The Americans with Disabilities Act of 1990, as amended (the “Americans with Disabilities Act”) generally requires that public buildings, including our properties, be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. Claims have been asserted, and in the future claims may be asserted, against us with respect to some of our properties or operations under the Americans with Disabilities Act. If, under the Americans with Disabilities Act, we are required to make substantial alterations and capital expenditures in one or more of our properties or otherwise related to our operations, including the removal of access barriers, it could adversely affect our financial condition and results of operations. In addition, if claims arise, we may expend resources and incur costs in investigating and resolving such claims even if we or our property was in compliance with the law.

Our properties are subject to various federal, state and local regulatory requirements, such as state and local fire and life safety requirements and federal, state and local accessibility requirements in addition to those imposed by the Americans with Disabilities Act. If we fail to comply with these requirements, we could incur fines or private damage awards. We do not know whether existing requirements will change or whether compliance with future requirements will require significant unanticipated expenditures that could adversely affect our financial condition or results of operations.

The Adoption of, or Changes to, Rent Control, Rent Stabilization, Eviction, Tenants’ Rights and Similar Laws and Regulations in Our Markets Could Have an Adverse Effect on Our Results of Operations and Property Values. Various state and local governments as well as the Federal government have enacted and may continue to enact rent control, rent stabilization, or limitations, and similar laws, regulations and policies that could limit our ability to raise rents or charge certain fees, including laws or court orders, either of which could have a retroactive effect. For example, in June 2019, the State of New York enacted new rent control regulations known as the Housing Stability and Tenant Protection Act of 2019 and, in October of 2019, the State of California enacted the Tenant Protection Act of 2019. We have seen a recent increase in governments enacting or considering, or being urged to consider, such laws and regulations. Federal, state and local governments or courts also have made, and may make in the future, changes to laws related to allowable fees and rents, eviction and other tenants’ rights laws and regulations (including changes that apply retroactively) that could adversely impact our results of operations and the value of our properties. Laws and regulations regarding rent control, rent stabilization, eviction, tenants’ rights, and similar matters, as well as any lawsuits against us arising from such laws and regulations, may limit our ability to charge market rents, increase rents, evict delinquent tenants or charge fees, or recover increases in our operating expenses, which could have an adverse effect on our results of operations and the value of our properties.

Compliance with or Changes in Real Estate Tax and Other Laws and Regulations Could Adversely Affect Our Funds from Operations and Our Ability to Make Distributions to Stockholders. We are subject to federal, state and local laws, regulations, rules and ordinances at locations where we operate regarding a wide variety of matters that could affect, directly or indirectly, our operations. Generally, we do not directly pass through costs resulting from compliance with or changes in real estate tax laws to residential property tenants. We also do not generally pass through increases in income, service or other taxes to tenants under leases. These costs may adversely affect net operating income and the ability to make distributions to stockholders. Similarly, compliance with or changes in (i) laws increasing the potential liability for environmental conditions existing on properties or the restrictions on discharges or other conditions, (ii) laws and regulations regulating housing, such as the Americans with Disabilities Act and the Fair Housing Amendments Act of 1988, or (iii) employment related laws, among others, may result in significant unanticipated expenditures, which could adversely affect our financial condition and results of operations. In addition, changes in federal and state legislation and regulation on climate change may result in increased capital expenditures to improve the energy efficiency of our existing communities and also may require us to spend more on our new development communities 20

Table of Contents without a corresponding increase in revenue. In addition, existing laws could be interpreted in a manner that restricts our ability to use systems that we currently use in our operations and we may face litigation or regulatory risk in connection with such laws. Future compliance with new laws of general applicability, laws applicable to companies in our industry, or laws applicable to public companies generally could increase our costs and could have an adverse effect on our financial performance.

Risk of Litigation. From time to time, we are involved in legal proceedings, lawsuits, and other claims with respect to our properties or operations. For example, we are currently a defendant in a consolidated class action lawsuit and a lawsuit filed by the District of Columbia involving RealPage, which is one of our vendors.^^An unfavorable resolution of any litigation may have a material adverse effect on our business, results of operations and financial condition. Additionally, litigation may result in substantial costs and expenses and significantly divert the attention of management.

Risk of Damage from Catastrophic Weather and Natural Events. Our communities are located in areas that have experienced, and in the future may experience, catastrophic weather and other natural events from time to time, including mudslides, fires, hurricanes, tornadoes, floods, deep freezes, snow or ice storms, or other severe inclement weather. These adverse weather and natural events could cause damage or losses that may be greater than insured levels. In the event of a loss in excess of insured limits, we could lose our capital invested in the affected community, as well as anticipated future revenue from that community. We would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community. Any such loss could adversely affect our financial condition and results of operations.

Risk of Potential Climate Change. To the extent significant changes in the climate in areas where our communities are located occur, we may experience extreme weather conditions and changes in precipitation and temperature or water levels, all of which could result in physical damage to, and/or a decrease in demand for, our communities located in these areas or communities that are otherwise affected by these changes. Should the impact of such climate changes be material in nature, or occur for lengthy periods of time, our financial condition and results of operations could be adversely affected.

Risk of Earthquake Damage. Some of our communities are located in areas subject to earthquakes, including in the general vicinity of earthquake faults. We cannot assure you that an earthquake would not cause damage or losses greater than insured levels. In the event of a loss in excess of insured limits, we could lose our capital invested in the affected community, as well as anticipated future revenue from that community. We may also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community. Any such loss could adversely affect our financial condition and results of operations. Insurance coverage for earthquakes can be costly due to limited industry capacity. As a result, we may experience shortages in desired coverage levels if market conditions are such that insurance is not available or the cost of insurance makes it, in management’s view, economically impractical.

Risk of Accidental Death or Injury Due to Fire, Natural Disasters or Other Hazards. The accidental death or injury of persons living in our communities due to fire, natural disasters, other hazards, or acts or omissions of third parties could have an adverse effect on our business and results of operations. Our insurance coverage may not cover all losses associated with such events, and we may experience difficulty marketing communities where any such events have occurred, which could have an adverse effect on our financial condition and results of operations.

Actual or Threatened Terrorist Attacks May Have an Adverse Effect on Our Business and Operating Results and Could Decrease the Value of Our Assets. Actual or threatened terrorist attacks and other acts of violence, destruction or war could have an adverse effect on our business and operating results. Attacks or other similar actions that directly impact one or more of our apartment communities could significantly affect our ability to operate those communities and thereby impair our ability to achieve our expected results. Further, our insurance coverage may not cover all losses caused by a terrorist attack or similar events. In addition, the adverse effects that such violent acts and threats of future attacks could have on the U.S. economy could similarly have an adverse effect on our financial condition and results of operations.

Mezzanine Loan or Other Loan Assets Involve Greater Risks of Loss than Senior Loans Secured by Income-Producing Properties. We have originated in the past and may in the future originate mezzanine loans, which take the form of subordinated loans secured by second mortgages on the underlying property, which may be under development, or subordinated loans secured by a pledge of the ownership interests of either the entity owning the property, which may be under development, or a pledge of the ownership interests of the entity that owns the interest in the entity owning the property, which may be under development, or loans that are not secured. Mezzanine loans may involve a higher degree 21

Table of Contents of risk than a senior mortgage secured by real property, because the security for the loan may lose all or substantially all of its value as a result of foreclosure by the senior lender and because it is in second position and there may not be adequate equity in the property and unsecured loans involve higher risk by virtue of being unsecured. In the event of a bankruptcy of the entity providing the pledge of its ownership interests as security, we may not have full recourse to the assets of such entity, or the assets of the entity may not be sufficient to satisfy our mezzanine loan. If a borrower defaults on our loan or debt senior to our loan, or in the event of a borrower bankruptcy, our mezzanine or other loan will be satisfied only after the senior debt. As a result, we may not recover some of or all our investment. In addition, mezzanine loans typically have higher loan-to-value ratios than conventional mortgage loans, resulting in less equity in the property and increasing the risk of loss of principal. Further, foreclosing on our security interest may be delayed or otherwise impacted by the existence of the senior loan, the senior lender’s decision regarding whether to enforce its remedies, or the timing of the senior lender’s foreclosure or enforcement of other remedies with respect to such loan. If there is a default on the senior debt or an inability to refinance the senior debt, we may contribute additional capital or take other actions that we would not otherwise pursue absent such default or failure. In addition, in the event of a default or other changes in the circumstances of an investment, including a change in the value of the applicable property, we may be required to change the manner in which the investment is accounted for, including our ability to recognize earnings, or recognize an allowance for loan loss or a loss on consolidation.

Risk Related to Preferred Equity Investments. We have made in the past and may in the future make preferred equity investments in corporations, limited partnerships, limited liability companies or other entities that have been formed for the purpose of directly or indirectly acquiring, developing and/or managing real property. Generally, we will not have the ability to control the daily operations of the entity, and we will not have the ability to select or remove a majority of the members of the board of directors, managers, general partner or partners or similar governing body of the entity or otherwise control its operations. Although we would seek to maintain sufficient influence over the entity to achieve our objectives, our partners may have interests that differ from ours and may be in a position to take actions without our consent that are inconsistent with our interests. Further, if our partners were to fail to invest additional capital in the entity when required, which has happened in the past, or otherwise do not perform as expected, we may have to invest additional capital to protect our investment. Our partners have in the past failed, and may in the future fail, to develop or operate the real property, operate the entity, refinance property indebtedness or sell the real property in the manner intended and as a result the entity may not be able to redeem our investment or pay the return expected to us in a timely manner or at all. In addition, we may not be able to dispose of our investment in the entity in a timely manner or at the price at which we would want to divest or at all. Further, the entity may need to refinance third-party debt on terms that are inconsistent with our interests or are terms on which we would not elect to incur debt, or the entity may default on third-party debt. To the extent the entity defaults on third-party debt or is unable to refinance such debt or a portion thereof, we may acquire such debt or otherwise take action, including contributing additional capital, to protect our position that we would not take absent the default or inability to refinance. Such activities have in the past involved and may in the future involve foreclosing on the security interest in the property secured by such debt or seeking a deed-in-lieu of foreclosure or similar remedy, and such activities may involve delays or create other risks, including the risk of claims from our partners. In the event that such an entity fails to meet expectations, defaults on its debt, or becomes insolvent or the investment or the underlying property otherwise does not perform as expected, we may lose all or part of our investment in the entity, be delayed in recovering our investment or the expected returns or directly or indirectly take over the property or the management thereof at a time at which we would not done so absent the failure to meet expectations or the default. In addition, in the event of a default or other changes in the circumstances of an investment, including a change in the value of the applicable property, we may be required to change the manner in which the investment is accounted for, including our ability to recognize earnings, or recognize an impairment or a loss on consolidation.

Risks Related to Ground Leases. We have entered into in the past and may in the future enter into, as either landlord or tenant, a long-term ground lease with respect to a property or a portion thereof. Such ground leases may contain a rent reset provision that requires both parties to agree to a new rent or is based upon factors, for example fair market rent, that are not objective and are not within our control. We may not be able to agree with the counterparty to a revised rental rate, or the revised rental rate may be set by external factors, which could result in a different rental rate than we forecasted. In the past we have had disagreements with respect to revised rental rates and certain of such disagreements have gone to arbitration (for resolution as provided in the applicable lease agreement) and have been resolved in a manner adverse to us. In addition, the other party may not perform as expected under the ground lease or there may be a dispute with the other party to the ground lease. Any of these circumstances could have an adverse effect on our business, financial condition or operating results. 22

Table of Contents We May Experience a Decline in the Fair Value of Our Assets and Be Forced to Recognize Impairment Charges, Which Could Adversely Impact Our Financial Condition, Liquidity and Results of Operations and the Market Price of Our Common Stock. A decline in the fair value of our assets may require us to recognize an impairment against such assets under generally accepted accounting principles as in effect in the United States (“GAAP”) if we were to determine that, with respect to any assets in unrealized loss positions, we do not have the ability and intent to hold such assets for a period of time sufficient to allow for recovery to the amortized cost of such assets. If such a determination were to be made, we would recognize unrealized losses through earnings and write down the amortized cost of such assets to a new cost basis, based on the fair value of such assets on the date they are considered to be impaired. Such impairment charges reflect non-cash losses at the time of recognition; subsequent disposition or sale of such assets could further affect our future losses or gains, as they are based on the difference between the sale price received and adjusted amortized cost of such assets at the time of sale. If we are required to recognize asset impairment charges in the future, these charges could adversely affect our financial condition, liquidity, results of operations and the market price of our common stock.

Any Material Weaknesses Identified in Our Internal Control Over Financial Reporting Could Have an Adverse Effect on the Market Price of Our Common Stock. Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate and report on our internal control over financial reporting. If we fail to maintain the adequacy of our internal controls over financial reporting, including any failure to implement required new or improved controls as a result of changes to our business or otherwise, or if we experience difficulties in their implementation, our business, results of operations and financial condition could be materially and adversely affected and we could fail to meet our reporting obligations. In addition, if we have one or more material weaknesses in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, which in turn could have an adverse effect on the market price of our common stock.

A Breach of Information Technology Systems On Which We Rely Could Materially and Adversely Impact Our Business, Financial Condition, Results of Operations and Reputation. We rely on information technology systems, including the internet and networks and systems and software developed, maintained and controlled by third party vendors and other third parties, to process, transmit and store information and to manage or support our business processes. Third party vendors may collect and hold personally identifiable information and other confidential information of our tenants, prospective tenants and employees. We also maintain such information and financial and business information regarding us and persons and entities with which we do business on our information technology systems. While we take steps, and generally require third party vendors to take steps, to protect the security of the information maintained in our and third party vendors’ information technology systems, including associate training and testing and the use of commercially available systems, software, tools and monitoring to provide security for processing, transmitting and storing of the information, it is possible that our or our third party vendors’ security measures will not be able to prevent human error or the systems’ or software’s improper functioning, or the loss, misappropriation, disclosure or corruption of personally identifiable information or other confidential or sensitive information, including information about our tenants and employees. Cybersecurity breaches, including physical or electronic break-ins, computer viruses, malware, phishing scams, attacks by hackers, breaches due to employee error or misconduct, and similar breaches, can create system disruptions, shutdowns or unauthorized access to information maintained on our information technology systems or the information technology systems of our third party vendors or other third parties or otherwise cause disruption or negative impacts to occur to our business and adversely affect our financial condition and results of operations. While we maintain cyber risk insurance to provide some coverage for certain risks arising out of cybersecurity breaches, there is no assurance that such insurance would cover all or a significant portion of the costs or consequences associated with a cybersecurity breach or other occurrence or that such insurance will continue to be available at rates that we consider reasonable or at all. We have in the past experienced cybersecurity breaches on our information technology systems or relating to software that we utilize, and, while none to date have been material, we expect such breaches may occur in the future. As the techniques used to obtain unauthorized access to information technology systems become more varied and sophisticated and the occurrence of such breaches becomes more frequent, we and our third party vendors and other third parties may be unable to adequately anticipate these techniques or breaches or implement appropriate preventative measures. Any failure to prevent cybersecurity breaches and maintain the proper function, security and availability of our or our third party vendors’ and other third parties’ information technology systems could interrupt our operations, damage our reputation and brand, damage our competitive position, make it difficult for us to attract and retain residents or other tenants, and subject us to liability claims or regulatory penalties that could adversely affect our business, financial condition and results of operations.

Our Business and Operations Would Suffer in the Event of Information Technology System Failures. Despite system redundancy and the existence of disaster recovery plans for our information technology systems, our information 23

Table of Contents technology systems and the information technology systems maintained by our third party vendors are vulnerable to damage arising from any number of sources beyond our or our third party vendors’ control, including energy blackouts, natural disasters, terrorism, war, and telecommunication failures. Any failure to maintain proper function and availability of our or third parties’ information technology systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could adversely affect our business, financial condition and results of operations.

A Failure to Keep Pace with Developments in Technology Could Impair our Operations or Competitive Position. Our business continues to demand the use of sophisticated systems, software and technology. These systems, software and technologies must be refined, updated and replaced on a regular basis in order for us to meet our business requirements and our residents’ demands and expectations. If we are unable to do so on a timely basis or at a reasonable cost, or fail to do so, our business could suffer. Also, we may not achieve the benefits that we anticipate from any new system, software or technology, and a failure to do so could result in higher than anticipated costs or could adversely affect our results of operations.

Social Media Presents Risks. The use of social media could cause us to suffer brand damage or unintended information disclosure. Negative posts or communications about us on a social networking website could damage our reputation. Further, employees or others may disclose non-public information regarding us or our business or otherwise make negative comments regarding us on social networking or other websites, which could adversely affect our business and results of operations. As social media evolves, we will be presented with new risks and challenges.

Our Success Depends on Our Senior Management. Our success depends upon the retention of our senior management, whose continued service is not guaranteed. We may not be able to find qualified replacements for the individuals who make up our senior management if their services should no longer be available to us. The loss of services of one or more members of our senior management team could have a material adverse effect on our business, financial condition and results of operations.

Changes in U.S. Accounting Standards May Materially and Adversely Affect Our Reported Results of Operations. Accounting for public companies in the United States is in accordance with GAAP, which is established by the Financial Accounting Standards Board (the “FASB”), an independent body whose standards are recognized by the SEC as authoritative for publicly held companies. Uncertainties posed by various initiatives of accounting standard-setting by the FASB and the SEC, which create and interpret applicable accounting standards for U.S. companies, may change the financial accounting and reporting standards or their interpretation and application of these standards that govern the preparation of our financial statements. These changes could have a material impact on our reported financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in potentially material restatements of prior period financial statements.

Third-Party Expectations Relating to Environmental, Social and Governance Factors May Impose Additional Costs and Expose Us to New Risks. There is an increasing focus from certain investors, tenants, employees, and other stakeholders concerning corporate responsibility, specifically related to environmental, social and governance factors. In addition, there is an increased focus on such matters by various regulatory authorities, including the SEC and the state of California, and the activities and expense required to comply with new laws, regulations or standards may be significant. Some investors may use these factors to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our policies relating to corporate responsibility are inadequate. Third-party providers of corporate responsibility ratings and reports on companies have increased in number, resulting in varied and in some cases inconsistent standards. In addition, the criteria by which companies’ corporate responsibility practices are assessed and the regulations applicable thereto are evolving, which could result in greater expectations of us and cause us to undertake costly initiatives or activities to satisfy such new criteria or regulations. Further, if we elect not to or are unable to satisfy such new criteria or do not meet the criteria of a specific third-party provider or investor, some investors may conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational damage in the event that our corporate responsibility procedures or standards do not meet the standards set by various constituencies. Furthermore, if our competitors’ corporate responsibility performance is perceived to be greater than ours, potential or current investors may elect to invest in our competitors instead. In addition, we have communicated certain initiatives and goals regarding environmental, social and governance matters, and we may in the future communicate revised or additional initiatives or goals. We could fail, or be perceived to fail, in our achievement of such initiatives or goals, or we could be criticized for the scope of such initiatives or goals. If we fail to satisfy the expectations of investors, tenants and other stakeholders, our initiatives are not executed as planned, or we do not satisfy our goals, our reputation and financial results could be adversely affected. 24

Table of Contents Risks Related to Our Indebtedness and Financings

Changing Interest Rates Could Increase Interest Costs and Adversely Affect Our Cash Flows and the Market Price of Our Common Stock. We currently have, and expect to incur in the future, interest-bearing debt, including unsecured commercial paper, at rates that vary with market interest rates. As of December 31, 2023, we had approximately $479.7 million of variable rate indebtedness outstanding, which constitutes approximately 8.3% of total outstanding indebtedness as of such date, and we have experienced increases in the interest rates on such indebtedness, which has increased our interest expense and adversely impacted our results of operations and cash flows. In addition, as a result of rising interest rates, the costs of hedging transactions have increased significantly and may continue to increase. Continued increases in interest rates would further increase our interest expenses and increase the costs of refinancing existing indebtedness and of issuing new debt, including unsecured commercial paper. The effect of prolonged interest rate increases could negatively impact our ability to service our indebtedness, make distributions to security holders, make acquisitions and develop properties.

Insufficient Cash Flow Could Affect Our Debt Financing and Create Refinancing Risk. We are subject to the risks normally associated with debt financing, including the risk that our operating income and cash flow could be insufficient to make required payments of principal and interest, could restrict or limit our ability to incur additional debt, or could restrict our borrowing capacity under our line of credit due to debt covenant restraints. Sufficient cash flow may not be available to make all required debt payments and satisfy our distribution requirements to maintain our status as a REIT for federal income tax purposes. In addition, the amounts under our line of credit may not be available to us and we may not be able to access the commercial paper market if our operating performance falls outside the constraints of our debt covenants. We are also likely to need to refinance substantially all of our outstanding debt as it matures. We may not be able to refinance existing debt, or the terms of any refinancing may not be as favorable as the terms of the existing debt, which could create pressure to sell assets or to issue additional equity when we would otherwise not choose to do so. In addition, our failure to comply with our debt covenants could result in a requirement to repay our indebtedness prior to its maturity, which could have a material adverse effect on our financial condition and cash flow, increase our financing costs and impact our ability to make distributions to our stockholders.

Failure to Generate Sufficient Income Could Impair Debt Service Payments and Distributions to Stockholders. If our apartment communities do not generate sufficient revenue to meet rental expenses, our ability to make required payments of interest and principal on our debt and to pay dividends or distributions to our stockholders will be adversely affected. The following factors, among others, may affect the income generated by our apartment communities:

the national and local economies;
local real estate market conditions, such as an oversupply of apartment homes;
--- ---
tenants’ or prospective tenants’ perceptions of the safety, convenience, and attractiveness of our communities and the neighborhoods where they are located;
--- ---
our ability to provide adequate management, maintenance and insurance;
--- ---
rental expenses, including real estate taxes and utilities;
--- ---
competition from other apartment communities or alternative housing options;
--- ---
changes in interest rates and the availability of financing;
--- ---
changes in governmental regulations and the related costs of compliance; and
--- ---
changes in tax and housing laws, including the enactment of rent control laws or other laws regulating multifamily housing.
--- ---

Expenses associated with our investment in an apartment community, such as debt service, real estate taxes, insurance, labor costs and maintenance costs, are generally not reduced when circumstances cause a reduction in revenue from that community. If a community is mortgaged to secure payment of debt and we are unable to make the mortgage payments, we could sustain a loss as a result of foreclosure on the community or the exercise of other remedies by the mortgage holder.

Our Debt Level May Be Increased. Our ability to incur debt is limited by covenants in our bank and other credit agreements. We manage our debt to be in compliance with these debt covenants, but subject to compliance with these 25

Table of Contents covenants, we may increase the amount of our debt at any time without a concurrent improvement in our ability to service the additional debt.

Financing May Not Be Available and Could Be Dilutive. Our ability to execute our business strategy depends on our access to an appropriate blend of debt financing, including unsecured lines of credit, construction loans and other forms of secured debt, commercial paper and other forms of unsecured debt, and equity financing, including common and preferred equity. We and other companies in the real estate industry have experienced limited availability of financing from time to time, including due to disruptions and uncertainty in the equity and credit markets and regulatory changes directly or indirectly affecting financing markets, for example the changes in terms on construction loans brought about by the Basel III capital requirements and the associated “High Volatility Commercial Real Estate” designation, which has adversely impacted the availability of loans, including construction loans, and the proceeds of and the interest rates thereon. Restricted lending practices could impact our ability to obtain financing or refinancing for our properties. If we issue additional equity securities to finance developments and acquisitions instead of incurring debt, the interests of our existing stockholders could be diluted.

Failure To Maintain Our Current Credit Ratings Could Adversely Affect Our Cost of Funds, Related Margins, Liquidity, and Access to Capital Markets. Moody’s and Standard & Poor’s routinely evaluate our debt and have given us ratings on our senior unsecured debt, commercial paper program and preferred stock. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, and sustainability of cash flows and earnings. Due to changes in these factors and market conditions, we may not be able to maintain our current credit ratings, which could adversely affect our cost of funds and related margins, liquidity, and access to capital markets, including our ability to access the commercial paper market.

Disruptions in Financial Markets May Adversely Impact the Availability and Cost of Credit and Have Other Adverse Effects on Us and the Market Price of Our Common Stock. Our ability to make scheduled payments on, or to refinance, our debt obligations will depend on our operating and financial performance, which in turn is subject to prevailing economic conditions and to financial, business and other factors beyond our control. The global equity and credit markets have experienced in the past, and may experience in the future, periods of extraordinary turmoil and volatility. These circumstances may materially and adversely impact liquidity in the financial markets at times, making terms for certain financings less attractive or in some cases unavailable. Disruptions and uncertainty in the equity and credit markets, including as a result of bank failures and uncertainty in the banking sector generally, may negatively impact our ability to refinance existing indebtedness and access additional financing for acquisitions, development of our properties and other purposes at reasonable terms or at all, which may negatively affect our business and the market price of our common stock. We also rely on the financial institutions that are parties to our revolving credit facility and other credit facilities. If these institutions become capital constrained, tighten their lending standards or become insolvent or if they experience excessive volumes of borrowing requests from other borrowers within a short period of time, they may be unable or unwilling to honor their funding commitments to us, which would adversely affect our ability to draw on our revolving credit facility. If we are not successful in refinancing our existing indebtedness when it becomes due, we may be forced to dispose of properties on disadvantageous terms, which might adversely affect our ability to service other debt and to meet our other obligations. A prolonged downturn in the financial markets may cause us to seek alternative sources of potentially less attractive financing and may require us to adjust our business plan accordingly. These events also may make it more difficult or costly for us to raise capital through the issuance of our common or preferred stock.

A Change in U.S. Government Policy or Support Regarding Fannie Mae or Freddie Mac Could Have a Material Adverse Impact on Our Business. While in recent years we have decreased our borrowings from Fannie Mae and Freddie Mac, Fannie Mae and Freddie Mac are a major source of financing to participants in the multifamily housing markets including potential purchasers of our properties. Potential options for the future of agency mortgage financing in the U.S. have been, and may in the future be, suggested that could involve a reduction in the amount of financing Fannie Mae and Freddie Mac are able to provide, limitations on the loans that the agencies may make, which may not include loans secured by properties like our properties, or the phase out of Fannie Mae and Freddie Mac. While we believe Fannie Mae and Freddie Mac will continue to provide liquidity to our sector, should they discontinue doing so, have their mandates changed or reduced or be disbanded or reorganized by the government, or if there is reduced government support for multifamily housing generally, it may adversely affect interest rates, capital availability, development of multifamily communities and the value of multifamily residential real estate and, as a result, may adversely affect our business and results of operations.

The Soundness of Financial Institutions Could Adversely Affect Us. We have relationships with many financial institutions, including lenders under our credit facilities, and, from time to time, we execute transactions with 26

Table of Contents counterparties in the financial services industry. Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, could result in losses or defaults by these institutions or counterparties or could lead to market-wide liquidity problems. Disruptions and uncertainty with respect to financial institutions, including as a result of bank failures and liquidity concerns, may negatively impact our ability to refinance existing indebtedness and access additional financing for acquisitions, development of our properties and other purposes at reasonable terms or at all, which may negatively affect our business and the market price of our common stock. In addition, in the event that the volatility of the financial markets adversely affects our financial institutions or other counterparties, we or other parties to the transactions with us may be unable to complete transactions as intended, which could adversely affect our results of operations.

Interest Rate Hedging Contracts May Be Ineffective and May Result in Material Charges. From time to time when we anticipate issuing debt securities, we may seek to limit our exposure to fluctuations in interest rates during the period prior to the pricing of the securities by entering into interest rate hedging contracts. We may do this to increase the predictability of our financing costs. Also, from time to time we may rely on interest rate hedging contracts to limit our exposure under variable rate debt to unfavorable changes in market interest rates. If the terms of new debt securities are not within the parameters of, or market interest rates fall below that which we incur under a particular interest rate hedging contract, the contract is ineffective. Furthermore, the settlement of interest rate hedging contracts has involved and may in the future involve material charges. In addition, our use of interest rate hedging arrangements may expose us to additional risks, including a risk that a counterparty to a hedging arrangement may fail to honor its obligations. Developing an effective interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations. There can be no assurance that our hedging activities will have the desired beneficial impact on our results of operations or financial condition. Termination of these hedging agreements typically involves costs, such as transaction fees or breakage costs.

Risks Related to Tax Laws

We Would Incur Adverse Tax Consequences if We Failed to Qualify as a REIT. We have elected to be taxed as a REIT under the Code. Our qualification as a REIT requires us to satisfy numerous requirements, some on an annual and quarterly basis, established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. We intend that our current organization and method of operation will enable us to continue to qualify as a REIT, but we may not so qualify or we may not be able to remain so qualified in the future. In addition, U.S. federal income tax laws governing REITs and other corporations and the administrative interpretations of those laws may be amended at any time, potentially with retroactive effect. Future legislation, new regulations, administrative interpretations or court decisions could adversely affect our ability to qualify as a REIT or adversely affect our stockholders.

If we fail to qualify as a REIT in any taxable year, we would be subject to federal income tax on our taxable income at regular corporate rates, and would not be allowed to deduct dividends paid to our stockholders in computing our taxable income. Also, unless the Internal Revenue Service granted us relief under certain statutory provisions, we could not re-elect REIT status until the fifth calendar year after the year in which we first failed to qualify as a REIT. The additional tax liability from the failure to qualify as a REIT would reduce or eliminate the amount of cash available for investment or distribution to our stockholders. This would likely have a significant adverse effect on the value of our securities and our ability to raise additional capital. In addition, we would no longer be required to make distributions to our stockholders. Even if we continue to qualify as a REIT, we will continue to be subject to certain federal, state and local taxes on our income and property.

Certain of our subsidiaries have also elected to be taxed as REITs under the Code, and are therefore subject to the same risks in the event that any such subsidiary fails to qualify as a REIT in any taxable year.

Dividends Paid by REITs Generally Do Not Qualify for Reduced Tax Rates. In general, the maximum U.S. federal income tax rate for dividends paid to individual U.S. stockholders is 20%. Unlike dividends received from a corporation that is not a REIT, our regular dividends (i.e., dividends other than capital gain dividends) paid to individual stockholders generally are not eligible for the reduced rates. However, individual U.S. stockholders generally may deduct 20% of such regular dividends under Section 199A of the Code, reducing the effective tax rate applicable to such dividends (although such provision will expire after 2025 absent future legislation). 27

Table of Contents We Conduct a Portion of Our Business Through Taxable REIT Subsidiaries, Which Are Subject to Certain Tax Risks. We have established or invested in and conduct a portion of our business through taxable REIT subsidiaries. Despite our qualification as a REIT, taxable REIT subsidiaries must pay income tax on their taxable income. In addition, we must comply with various tests to continue to qualify as a REIT for federal income tax purposes, and our income from and investments in taxable REIT subsidiaries generally do not constitute permissible income and investments for certain of these tests. While we will attempt to ensure that our dealings with taxable REIT subsidiaries will not adversely affect our REIT qualification, we cannot provide assurance that we will successfully achieve that result. Furthermore, we may be subject to a 100% penalty tax, we may jeopardize our ability to retain future gains on real property sales, or taxable REIT subsidiaries may be denied deductions, to the extent our dealings with taxable REIT subsidiaries are not deemed to be arm’s length in nature or are otherwise not respected.

REIT Distribution Requirements Limit Our Available Cash. As a REIT, we are subject to annual distribution requirements, which limit the amount of cash we retain for other business purposes, including amounts to fund our growth. We generally must distribute annually at least 90% of our net REIT taxable income, excluding any net capital gain, in order for our distributed earnings not to be subject to corporate income tax. We intend to make distributions to our stockholders to comply with the requirements of the Code. However, differences in timing between the recognition of taxable income and the actual receipt of cash could require us to sell assets or borrow funds on a short-term or long-term basis to meet the 90% distribution requirement of the Code.

Certain Property Transfers May Generate Prohibited Transaction Income, Resulting in a Penalty Tax on Gain Attributable to the Transaction. From time to time, we may transfer or otherwise dispose of some of our properties. Under the Code, any gain resulting from transfers of properties that we hold as inventory or primarily for sale to customers in the ordinary course of business would be treated as income from a prohibited transaction and subject to a 100% penalty tax. Since we acquire properties for investment purposes, we do not believe that our occasional transfers or disposals of property are prohibited transactions. However, whether property is held for investment purposes is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. The Internal Revenue Service may contend that certain transfers or disposals of properties by us are prohibited transactions. If the Internal Revenue Service were to argue successfully that a transfer or disposition of property constituted a prohibited transaction, then we would be required to pay a 100% penalty tax on any gain allocable to us from the prohibited transaction and we may jeopardize our ability to retain future gains on real property sales. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT for federal income tax purposes.

Changes to the U.S. Federal Income Tax Laws, including the Enactment of Certain Tax Reform Measures, Could Have an Adverse Impact on Our Business and Financial Results. In recent years, numerous legislative, judicial and administrative changes have been made to the U.S. federal income tax laws applicable to investments in real estate and REITs, and it is possible that additional legislation may be enacted in the future. There can be no assurance that future changes to the U.S. federal income tax laws or regulatory changes will not be proposed or enacted that could impact our business and financial results. The REIT rules are regularly under review by persons involved in the legislative process and by the Internal Revenue Service and the U.S. Treasury Department, which may result in revisions to regulations and interpretations in addition to statutory changes. If enacted, certain of such changes could have an adverse impact on our business and financial results.

We cannot predict whether, when or to what extent any new U.S. federal tax laws, regulations, interpretations or rulings will impact the real estate investment industry or REITs. Prospective investors are urged to consult their tax advisors regarding the effect of potential future changes to the federal tax laws on an investment in our shares.

We May Be Adversely Affected by Changes in State and Local Tax Laws and May Become Subject to Tax Audits from Time to Time. Because we are organized and qualify as a REIT, we are generally not subject to federal income taxes, but we are subject to certain state and local taxes. From time to time, changes in state and local tax laws or regulations may result in an increase in our tax liability. A shortfall in tax revenues for states and local jurisdictions in which we own apartment communities may lead to an increase in the frequency and size of such changes. If such changes occur, we may be required to pay additional state and local taxes. These increased tax costs could adversely affect our financial condition and the amount of cash available for the payment of distributions to our stockholders. In the normal course of business, we or our affiliates (including entities through which we own real estate) may also become subject to federal, state or local tax audits. If we (or such entities) become subject to federal, state or local tax audits, the ultimate result of such audits could have an adverse effect on our financial condition and results of operations. 28

Table of Contents The Operating Partnership and the DownREIT Partnership Intend to Qualify as Partnerships, but Cannot Guarantee That They Will Qualify. The Operating Partnership and the DownREIT Partnership intend to qualify as partnerships for federal income tax purposes, and we intend to take that position for all income tax reporting purposes. If classified as partnerships, the Operating Partnership and the DownREIT Partnership generally will not be taxable entities and will not incur federal income tax liability. However, the Operating Partnership and the DownREIT Partnership would be treated as corporations for federal income tax purposes if they were “publicly traded partnerships,” unless at least 90% of their income was qualifying income as defined in the Code. A “publicly traded partnership” is a partnership whose partnership interests are traded on an established securities market or are readily tradable on a secondary market (or the substantial equivalent thereof). Although neither the Operating Partnership’s nor the DownREIT Partnership’s partnership units are traded on an established securities market, because of the redemption rights of their limited partners, the Operating Partnership’s and DownREIT Partnership’s units held by limited partners could be viewed as readily tradable on a secondary market (or the substantial equivalent thereof), and the Operating Partnership and the DownREIT Partnership may not qualify for one of the “safe harbors” under the applicable tax regulations. Qualifying income for the 90% test generally includes passive income, such as real property rents, dividends and interest. The income requirements applicable to REITs and the definition of qualifying income for purposes of this 90% test are similar in most respects. The Operating Partnership and the DownREIT Partnership may not meet this qualifying income test. If either the Operating Partnership or the DownREIT Partnership were to be taxed as a corporation, it would incur substantial tax liabilities, and we would then fail to qualify as a REIT for tax purposes, unless it qualified for relief under certain statutory savings provisions, and our ability to raise additional capital would be impaired. In addition, even if the 90% test were met if the Operating Partnership or the DownREIT Partnership were a publicly traded partnership, there could be adverse tax impacts for certain limited partners.

Qualifying as a REIT Involves Highly Technical and Complex Provisions of the Code. Our qualification as a REIT involves the application of highly technical and complex Code provisions for which only limited judicial and administrative authorities exist. Even a technical or inadvertent violation could jeopardize our REIT qualification. Moreover, new legislation, court decisions or administrative guidance, in each case possibly with retroactive effect, may make it more difficult or impossible for us to qualify as a REIT. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our ability to satisfy the REIT income and asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination and for which we will not obtain independent appraisals, and upon our ability to successfully manage the composition of our income and assets on an ongoing basis. In addition, our ability to satisfy the requirements to qualify as a REIT depends in part on the actions of third parties over which we have no control or only limited influence, including in cases where we own an equity interest in an entity that is classified as a partnership for U.S. federal income tax purposes.

Risks Related to Our Organization and Ownership of Our Stock

Changes in Market Conditions and Volatility of Stock Prices Could Adversely Affect the Market Price of Our Common Stock. The stock markets, including the New York Stock Exchange (“NYSE”), on which we list our common stock, have experienced significant price and volume fluctuations. As a result, the market price of our common stock has been, and in the future could be similarly volatile, and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. In addition to the risks listed in this “Risk Factors” section, a number of factors could negatively affect the price per share of our common stock, including:

general market and economic conditions;
actual or anticipated variations in our quarterly operating results or dividends or our payment of dividends in shares of our stock;
--- ---
changes in our funds from operations or earnings estimates;
--- ---
difficulties or inability to access capital or extend or refinance existing debt;
--- ---
decreasing (or uncertainty in) real estate valuations;
--- ---
changes in market valuations of similar companies;
--- ---
publication of research reports about us or the real estate industry;

--- ---

Many of the factors listed above are beyond our control. These factors may cause the market price of shares of our common stock to decline, regardless of our financial condition, results of operations, business or prospects.

We May Change the Dividend Policy for Our Common Stock in the Future. The decision to declare and pay dividends on our common stock, as well as the timing, amount and composition of any such future dividends, will be at the sole discretion of our board of directors and will depend on our earnings, funds from operations, liquidity, financial condition, capital requirements, contractual prohibitions or other limitations under our indebtedness, the annual distribution requirements under the REIT provisions of the Code, state law and such other factors as our board of directors considers relevant. Any change in our dividend policy could have an adverse effect on the market price of our common stock.

Maryland Law May Limit the Ability of a Third Party to Acquire Control of Us, Which May Not be in Our StockholdersBest Interests. Maryland business statutes may limit the ability of a third party to acquire control of us. As a Maryland corporation, we are subject to various Maryland laws which may have the effect of discouraging offers to acquire our Company and of increasing the difficulty of consummating any such offers, even if our acquisition would be in our stockholders’ best interests. The Maryland General Corporation Law restricts mergers and other business combination transactions between us and any person who acquires beneficial ownership of shares of our stock representing 10% or more of the voting power without our board of directors’ prior approval. Any such business combination transaction could not be completed until five years after the person acquired such voting power, and generally only with the approval of stockholders representing 80% of all votes entitled to be cast and 66 2/3% of the votes entitled to be cast, excluding the interested stockholder, or upon payment of a fair price. Maryland law also provides generally that a person who acquires shares of our equity stock that represents 10% (and certain higher levels) of the voting power in electing directors will have no voting rights unless approved by a vote of two-thirds of the shares eligible to vote.

Limitations on Share Ownership and Limitations on the Ability of Our Stockholders to Effect a Change in Control of Our Company Restrict the Transferability of Our Stock and May Prevent Takeovers That are Beneficial to Our Stockholders. One of the requirements for maintenance of our qualification as a REIT for U.S. federal income tax purposes is that no more than 50% in value of our outstanding capital stock may be owned by five or fewer individuals, including entities specified in the Code, during the last half of any taxable year. Our charter contains ownership and transfer restrictions relating to our stock primarily to assist us in complying with this and other REIT ownership 30

Table of Contents requirements; however, the restrictions may have the effect of preventing a change of control which does not threaten our REIT status. These restrictions include a provision that generally limits ownership by any person of more than 9.9% of the value of our outstanding equity stock, unless our board of directors exempts the person from such ownership limitation, provided that any such exemption shall not allow the person to exceed 13% of the value of our outstanding equity stock. Absent such an exemption from our board of directors, the transfer of our stock to any person in excess of the applicable ownership limit, or any transfer of shares of such stock in violation of the ownership requirements of the Code for REITs, will be considered null and void, and the intended transferee of such stock will acquire no rights in such shares. These provisions of our charter may have the effect of delaying, deferring or preventing someone from taking control of us, even though a change of control might involve a premium price for our stockholders or might otherwise be in our stockholders’ best interests*.*

Item 1C. Cybersecurity

Given the prevalence of cybersecurity threats, cybersecurity represents a critical component of the Company’s overall approach to risk management. The Company’s cybersecurity policies, standards and practices are integrated into the Company’s enterprise risk management (“ERM”) approach, and cybersecurity risks are among the core enterprise risks that are subject to oversight by the Company’s Board of Directors (the “Board”). The Company’s cybersecurity policies, standards and practices are derived from recognized frameworks established by the National Institute of Standards and Technology (“NIST”) and other applicable industry standards, and the Company is working to obtain NIST certification. Many members of the Company’s cybersecurity team are certified by and have received training from the International Information Security Consortium (“IISC”). The Company generally approaches cybersecurity threats through a cross-functional, multilayered approach, with specific the goals of: (i) identifying, attempting to prevent and mitigating cybersecurity threats to the Company; (ii) preserving the confidentiality, security and availability of the information that we collect and store to use in our business; (iii) protecting the Company’s intellectual property; (iv) protecting personally identifiable data and maintaining the confidence of our customers, clients and business partners; and (v) providing appropriate public disclosure of cybersecurity risks and incidents when required.

Risk Management and Strategy

Consistent with overall ERM policies and practices, the Company’s cybersecurity program focuses on the following areas:

Vigilance: The Company operates cybersecurity threat functions 24/7 with the specific goal of identifying, attempting to prevent and mitigating cybersecurity threats and responding to cybersecurity incidents in accordance with our established incident response and recovery plans.
Systems Safeguards: The Company deploys systems safeguards that are designed to protect the Company’s information systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls, which are evaluated and improved through ongoing vulnerability assessments and cybersecurity threat intelligence.
--- ---
Collaboration: The Company utilizes collaboration mechanisms established with public and private entities, including intelligence and enforcement agencies, industry **** groups and third-party service providers, to identify, assess and respond to cybersecurity risks.
--- ---
Third-Party Risk Management: The Company maintains a risk-based approach to identifying and overseeing cybersecurity risks presented by third parties, including vendors, service providers and other external users of the Company’s systems, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems. Third-party vendors are assessed against a standardized vendor risk assessment process before being engaged and the Company requests vendors to annually recertify that their security controls comply with established industry standards and applicable legal requirements.

Insider Threat Management: In order to try to mitigate cybersecurity threats to our systems, the Company attempts to provide associates with the minimum access to our systems required in order for a given associate to perform his or her assigned duties. We also perform reviews of access to both our administrative and financial systems as part of our annual compliance procedures, and, when duties and resources allow, rotate job responsibilities.
Training: Upon employment and at least annually thereafter the Company provides mandatory training for our associates regarding cybersecurity threats, which reinforces the Company’s information security policies, standards and practices, and such training is scaled to reflect the roles, responsibilities, and information systems access of such personnel. The Company’s cybersecurity team performs regular phishing tests for associates and provides remedial training for associates who fail such tests. In addition, members of our cybersecurity team received specialized cybersecurity training.
--- ---
Incident Response and Recovery Planning: The Company has established and maintains incident response and recovery plans that address the Company’s response to a cybersecurity incident and the recovery from a cybersecurity incident, and such plans are assessed and evaluated on a regular basis. All meaningful cybersecurity incidents are reported to the Company’s legal department by our cybersecurity team.
--- ---
Governance, Communication, Coordination and Disclosure: The Company utilizes a cross-functional approach to address the risk from cybersecurity threats, involving management personnel from the Company’s technology, operations, legal, risk management, internal audit and other key business functions, third-party vendors and consultants, as well as the members of the Board and the Audit and Risk Management Committee of the Board (the “Audit Committee”) in an ongoing dialogue regarding cybersecurity threats and incidents, while also implementing controls and procedures for the escalation of cybersecurity incidents when appropriate so that decisions regarding the disclosure and reporting of such incidents can be made by management in a timely manner. Our Senior Vice President – Chief Technology Officer reports on our cybersecurity posture to the Audit Committee quarterly and the Board is updated at least annually.
--- ---

A key part of the Company’s strategy for managing risks from cybersecurity threats is the ongoing assessment and testing of the Company’s processes and practices through auditing, assessments, tabletop exercises, vulnerability testing and other exercises focused on evaluating the effectiveness of our cybersecurity measures. The Company engages third parties, including legal counsel, to perform assessments on our cybersecurity measures, including information security maturity assessments, penetration testing inclusive of our resident facing apps and devices, audits and independent reviews of our information security control environment and operating effectiveness. The material results of such assessments, audits and reviews are reported to the Audit Committee and the Board, and the Company adapts its cybersecurity policies, standards, processes, and practices as necessary based on the information provided by the assessments, audits, and reviews.^^In addition, in 2023 outside legal counsel conducted an exercise regarding preparation for cyber events attended by our Chairman and Chief Executive Officer, President and Chief Financial Officer and other members of senior management.

Governance

The Board, in coordination with the Audit Committee, oversees the management of risks from cybersecurity threats, including the policies, standards, processes and practices that the Company’s management implements to address risks from cybersecurity threats. The Board and the Audit Committee each receive presentations and reports on cybersecurity risks, which address a wide range of topics including, for example, recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the threat environment, new tools and vendors being used by the Company related to cybersecurity, technological trends and information security considerations arising with respect to the Company’s peers and third parties. The Board and the Audit Committee also receive information regarding any cybersecurity incident when appropriate, as well as ongoing updates regarding such incident until it has been addressed. At least once each year the Board and the Audit Committee at least quarterly discuss the Company’s approach to cybersecurity risk management with the Company’s Chief Technology Officer.

The Company’s Chief Technology Officer is the member of the Company’s management that is principally responsible for overseeing the Company’s cybersecurity risk management program, in partnership with other business leaders across the Company. The Chief Technology Officer and our Vice President, Information Security work in coordination with the other members of the Information Security Management System Committee (“ISMS”), which includes department heads and IT personnel. The Chief Technology Officer also provides monthly reports regarding 32

Table of Contents information technology including cybersecurity to our senior management including our Chairman and Chief Executive Officer, President and Chief Financial Officer, Senior Vice President – Chief Investment Officer, Senior Vice President – Operations, Senior Vice President – Chief Accounting Officer, Senior Vice President – Acquisitions and Dispositions, and Senior Vice President – General Counsel. The Company’s Chief Technology Officer has served in various roles in information technology and information security for over 23 years. The Chief Technology Officer holds an undergraduate degree in computer science and a master’s degree in business administration. The Company’s Vice President, Information Security holds an undergraduate degree in computer science and management science, has attained a professional certification of Certified Information Systems Security Professional (CISSP) from the IISC and has served in various roles in information technology and information security for over 15 years. In addition, our Vice President, Information Security is a member of InfraGard.

The Company’s Chief Technology Officer and Vice President, Information Security, in coordination with the ISMS, work collaboratively across the Company to implement a program designed to protect the Company’s information systems from cybersecurity threats and to promptly respond to any cybersecurity incidents. To facilitate the success of this program, our IT security team and, when necessary, multidisciplinary teams throughout the Company are deployed to address cybersecurity threats and to respond to cybersecurity incidents in accordance with the Company’s incident response and recovery plans. Through the ongoing communications from these teams, the Chief Technology Officer and the Vice President, Information Security monitor the prevention, detection, mitigation, and remediation of cybersecurity incidents, and report such incidents to the ISMS and other members of management and the Audit Committee or the Board when appropriate.

To date the Company has not been materially affected by a cybersecurity incident or cybersecurity threat and no incident has occurred that is reasonably likely to affect the Company, including its business strategy, results of operations, or financial condition. 33

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

Capital Stock

Common Stock

UDR, Inc.’s common stock has been listed on the New York Stock Exchange (“NYSE”) under the symbol “UDR” since May 7, 1990.

On February 16, 2024, there were 2,659 holders of record of the 329,224,105 outstanding shares of our common stock.

We have determined that, for federal income tax purposes, approximately 88% of the distributions for 2023 represented ordinary income, 10% represented long-term capital gain and 2% represented unrecaptured section 1250 gain.

UDR pays regular quarterly distributions to holders of its common stock. Future distributions will be at the discretion of our Board of Directors and will depend on our actual funds from operations, financial condition and capital requirements, the annual distribution requirements under the REIT provisions of the Code, and other factors.

Series E Preferred Stock

The Series E Cumulative Convertible Preferred Stock (“Series E”) has no stated par value and a liquidation preference of $16.61 per share. Subject to certain adjustments and conditions, each share of the Series E is convertible at any time at the holder’s option into 1.083 shares of our common stock. The holders of the Series E are entitled to vote on an as-converted basis as a single class in combination with the holders of common stock at any meeting of our stockholders for the election of directors or for any other purpose on which the holders of common stock are entitled to vote. The Series E has no stated maturity and is not subject to any sinking fund or any mandatory redemption. In connection with a special dividend (declared on November 5, 2008), the Company reserved for issuance upon conversion of the Series E additional shares of common stock to reflect the number of shares a holder of the Series E would have received if the holder had converted the Series E immediately prior to the record date for this special dividend.

Distributions declared on the Series E for the years ended December 31, 2023 and 2022 were $1.8192 per share, or $0.4548 per quarter, and $1.6456 per share, or $0.4114 per quarter, respectively. The Series E is not listed on any exchange. At December 31, 2023, a total of 2.7 million shares of the Series E were outstanding.

Series F Preferred Stock

We are authorized to issue up to 20.0 million shares of our Series F Preferred Stock (“Series F”). The Series F may be purchased by holders of limited partnership interests in the Operating Partnership and the DownREIT Partnership at a purchase price of $0.0001 per share. Certain OP/DownREIT unitholders were entitled to subscribe for and purchase one share of the Series F for each OP/DownREIT Unit held.

As of December 31, 2023, a total of 11.9 million shares of the Series F were outstanding. Holders of the Series F are entitled to one vote for each share of the Series F they hold, voting together with the holders of our common stock, on each matter submitted to a vote of security holders at a meeting of our stockholders. The Series F does not entitle its holders to any other rights, privileges or preferences.

Distribution Reinvestment and Stock Purchase Plan

We have a Distribution Reinvestment and Stock Purchase Plan under which holders of our common stock may elect to automatically reinvest their distributions and make additional cash payments to acquire additional shares of our common stock. Stockholders who do not participate in the plan continue to receive distributions as and when declared. As of February 16, 2024, there were approximately 1,703 participants in the plan. 35

Table of Contents Unregistered Sales of Equity Securities

From time to time we issue shares of our common stock in exchange for OP Units tendered to the Operating Partnership for redemption in accordance with the provisions of the Operating Partnership’s limited partnership agreement. Under the terms of the Operating Partnership’s limited partnership agreement, the holders of OP Units have the right to require the Operating Partnership to redeem all or a portion of the OP Units held by the holder in exchange for a cash payment based on the market value of our common stock at the time of redemption. However, the Operating Partnership’s obligation to pay the cash amount is subject to the prior right of the Company to acquire such OP Units in exchange for either the cash amount or the number of shares of our common stock equal to the number of OP Units being redeemed.

During the three months ended December 31, 2023, we did not issue any shares of our common stock upon redemption of OP Units in reliance upon an exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933.

Purchases of Equity Securities

In January 2008, UDR’s Board of Directors authorized a 15 million share repurchase program. Under the share repurchase program, UDR may repurchase shares of our common stock in open market purchases, block purchases, privately negotiated transactions or otherwise.

Business Overview

We are a self-administered real estate investment trust, or REIT, that owns, operates, acquires, renovates, develops, redevelops, disposes of, and manages multifamily apartment communities in targeted markets located in the United States. We were formed in 1972 as a Virginia corporation. In June 2003, we changed our state of incorporation from Virginia to Maryland. Our subsidiaries include the Operating Partnership and the DownREIT Partnership. Unless the context otherwise requires, all references in this Report to “we,” “us,” “our,” “the Company,” or “UDR” refer collectively to UDR, Inc., its consolidated subsidiaries and its consolidated joint ventures.

At December 31, 2023, our consolidated real estate portfolio included 168 communities in 13 states plus the District of Columbia totaling 55,550 apartment homes. In addition, we have an ownership interest in 10,045 completed or to-be-completed apartment homes through unconsolidated joint ventures or partnerships, including 5,618 apartment homes owned by entities in which we hold preferred equity investments. The Same-Store Community apartment home population for the year ended December 31, 2023, was 51,368.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles (“GAAP”) requires management to use judgment in the application of accounting policies, including making estimates and assumptions. A critical accounting policy is one that is both important to our financial condition and results of operations as well as involves some degree of uncertainty. Estimates are prepared based on management’s assessment after considering all evidence available. Changes in estimates could affect our financial position or results of 39

Table of Contents operations. Below is a discussion of the accounting policies that we consider critical to understanding our financial condition or results of operations where there is uncertainty or where significant judgment is required. A discussion of our significant accounting policies, including further discussion of the accounting policies described below, can be found in Note 2, Significant Accounting Policies, to the Notes to the UDR, Inc. Consolidated Financial Statements included in this Report.

Cost Capitalization

In conformity with GAAP, we capitalize those expenditures that materially enhance the value of an existing asset or substantially extend the useful life of an existing asset. Expenditures necessary to maintain an existing property in ordinary operating condition are expensed as incurred.

In addition to construction costs, we capitalize costs directly related to the predevelopment, development, and redevelopment of a capital project, which include, but are not limited to, interest, real estate taxes, insurance, and allocated development and redevelopment overhead related to support costs for personnel working on the capital projects. We use our professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. These costs are capitalized only during the period in which activities necessary to ready an asset for its intended use are in progress and such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. As each home in a capital project is completed and becomes available for lease-up, the Company ceases capitalization on the related portion. The costs capitalized are reported on the Consolidated Balance Sheets as Total real estate owned, net of accumulated depreciation. Amounts capitalized during the years ended December 31, 2023, 2022, and 2021 were $23.2 million, $31.3 million, and $21.0 million, respectively.

Investment in Unconsolidated Entities

We may enter into various joint venture agreements and/or partnerships with unrelated third parties to hold or develop real estate assets. We must determine for each of these ventures whether to consolidate the entity or account for our investment under the equity method of accounting. We determine whether to consolidate a joint venture or partnership based on our rights and obligations under the venture agreement, applying the applicable accounting guidance. The application of the rules in evaluating the accounting treatment for each joint venture or partnership is complex and requires substantial management judgment. We evaluate our accounting for investments on a regular basis including when a significant change in the design of an entity occurs. Throughout our financial statements, and in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, we use the term “joint venture” or “partnership” when referring to investments in entities in which we do not have a 100% ownership interest.

We continually evaluate our investments in unconsolidated joint ventures when events or changes in circumstances indicate that there may be an other-than-temporary decline in value. We consider various factors to determine if a decrease in the value of the investment is other-than-temporary. These factors include, but are not limited to, age of the venture, our intent and ability to retain our investment in the entity, the financial condition and long-term prospects of the entity, and the relationships with the other joint venture partners and its lenders. The amount of loss recognized is the excess of the investment’s carrying amount over its estimated fair value. If we believe that the decline in fair value is temporary, no impairment is recorded. The aforementioned factors are taken as a whole by management in determining the valuation of our investment property. Should the actual results differ from management’s judgment, the valuation could be negatively affected and may result in a negative impact to our Consolidated Financial Statements.

Impairment of Long-Lived Assets

Quarterly or when changes in circumstances warrant, we will assess our real estate properties for indicators

of impairment. The judgments regarding the existence of impairment indicators are based on certain factors. Such factors include, among other things, operational performance, market conditions, the Company’s intent and ability to hold the related asset, as well as any significant cost overruns on development properties.

If a real estate property has indicators of impairment, we assess whether the long-lived asset’s carrying value exceeds the community’s undiscounted future cash flows, which is representative of projected net operating income (“NOI”) plus the residual value of the community. Our future cash flow estimates are based upon historical results adjusted to reflect our best estimate of future market and operating conditions and our estimated holding periods. If such indicators of impairment are present and the carrying value exceeds the undiscounted cash flows of the community, an impairment loss is recognized equal to the excess of the carrying amount of the asset over its estimated fair value. Our estimates of fair value represent our best estimate based primarily upon unobservable inputs related to rental rates, 40

Table of Contents operating costs, growth rates, discount rates, capitalization rates, industry trends and reference to market rates and transactions.

For long-lived assets to be disposed of, impairment losses are recognized when the fair value of the asset less estimated cost to sell is less than the carrying value of the asset. Properties classified as real estate held for disposition generally represent properties that are actively marketed or contracted for sale with the closing expected to occur within the next twelve months. Real estate held for disposition is carried at the lower of cost, net of accumulated depreciation, or fair value, less the cost to sell, determined on an asset-by-asset basis. Expenditures for ordinary repair and maintenance costs on held for disposition properties are charged to expense as incurred. Expenditures for improvements, renovations, and replacements related to held for disposition properties are capitalized at cost. Depreciation is not recorded on real estate held for disposition.

Real Estate Investment Properties

We purchase real estate investment properties from time to time and record the fair value to various components, such as land, buildings, and intangibles related to in-place leases, based on the fair value of each component. In making estimates of fair values for purposes of allocating purchase price, we utilize various sources, including independent appraisals, our own analysis of recently acquired and existing comparable properties in our portfolio and other market data. The fair value of buildings is determined as if the buildings were vacant upon acquisition and subsequently leased at market rental rates. As such, the determination of fair value considers the present value of all cash flows expected to be generated from the property including an initial lease-up period. We determine the fair value of in-place leases by assessing the net effective rent and remaining term of the lease relative to market terms for similar leases at acquisition. In addition, we consider the cost of acquiring similar leases, the foregone rents associated with the lease-up period, and the carrying costs associated with the lease-up period. The fair value of in-place leases is recorded and amortized as amortization expense over the remaining average contractual lease period.

REIT Status

We are a Maryland corporation that has elected to be treated for federal income tax purposes as a REIT. A REIT is a legal entity that holds interests in real estate and is required by the Code to meet a number of organizational and operational requirements, including a requirement that a REIT must distribute at least 90% of our REIT taxable income (other than our net capital gain) to our stockholders. If we were to fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at the regular corporate rates and may not be able to qualify as a REIT for four years. Based on the net earnings reported for the year ended December 31, 2023 in our Consolidated Statements of Operations, we would have incurred federal and state GAAP income taxes if we had failed to qualify as a REIT. 41

These communities were owned and had stabilized occupancy and operating expenses as of the beginning of the prior year, there is no plan to conduct substantial redevelopment activities, and the communities are not classified as held for disposition at year end. A community is considered to have stabilized occupancy once it achieves 90% occupancy for at least three consecutive months. 42

Table of Contents Our Non-Mature Communities/Other segment represents those communities that do not meet the criteria to be included in Same-Store Communities, including, but not limited to, recently acquired, developed and redeveloped communities, and the non-apartment components of mixed use properties.

Liquidity and Capital Resources

Liquidity is the ability to meet present and future financial obligations either through operating cash flows, sales of properties, borrowings under our credit agreements, and/or the issuance of debt and/or equity securities. Our primary source of liquidity is our cash flow from operations, as determined by rental rates, occupancy levels, and operating expenses related to our portfolio of apartment homes, and borrowings under our credit agreements. We routinely use our working capital credit facility, our unsecured revolving credit facility and issuances of commercial paper to temporarily fund certain investing and financing activities prior to arranging for longer-term financing or the issuance of equity or debt securities. During the past several years, proceeds from the sale of real estate have been used for both investing and financing activities as we continue to execute on maintaining a diversified portfolio.

We expect to meet our short-term liquidity requirements generally through net cash provided by property operations and borrowings under our credit agreements and our unsecured commercial paper program. We expect to meet certain long-term liquidity requirements such as scheduled debt maturities, the repayment of financing on development activities, and potential property acquisitions, through net cash provided by property operations, secured and unsecured borrowings, the issuance of debt or equity securities, and/or the disposition of properties. We believe that our net cash provided by property operations and borrowings under our credit agreements and our unsecured commercial paper program will continue to be adequate to meet both operating requirements and the payment of dividends by the Company in accordance with REIT requirements. Likewise, the budgeted expenditures for improvements and renovations of certain properties are expected to be funded from property operations, borrowings under credit agreements, the issuance of debt or equity securities, and/or dispositions of properties.

We have a shelf registration statement filed with the Securities and Exchange Commission, or “SEC,” which provides for the issuance of common stock, preferred stock, depositary shares, debt securities, guarantees of debt securities, warrants, subscription rights, purchase contracts and units to facilitate future financing activities in the public capital markets. Access to capital markets is dependent on market conditions at the time of issuance.

In July 2021, the Company entered into an ATM sales agreement under which the Company may offer and sell up to 20.0 million shares of its common stock, from time to time, to or through its sales agents and may enter into separate forward sales agreements to or through its forward purchasers. Upon entering into the ATM sales agreement, the Company simultaneously terminated the sales agreement for its prior at-the-market equity offering program, which was entered into in July 2017. During the year ended December 31, 2023, the Company did not sell any shares of common stock through its ATM program. As of December 31, 2023, we had 14.0 million shares of common stock available for future issuance under the ATM program.

In connection with any forward sales agreement under the Company’s ATM program, the relevant forward purchasers will borrow from third parties and, through the relevant sales agent, acting in its role as forward seller, sell a number of shares of the Company’s common stock equal to the number of shares underlying the agreement. The Company does not initially receive any proceeds from any sale of borrowed shares by the forward seller.

During the year ended December 31, 2023, the Company repurchased 0.6 million shares of its common stock at an average price of $40.13 per share for total consideration of approximately $25.0 million under its share repurchase program.

Future Capital Needs

Future development and redevelopment expenditures may be funded through unsecured or secured credit facilities, unsecured commercial paper, proceeds from the issuance of equity or debt securities, sales of properties, joint ventures, and, to a lesser extent, from cash flows provided by property operations. Acquisition activity in strategic markets may be funded through joint ventures, by the reinvestment of proceeds from the sale of properties, through the issuance of equity or debt securities, the issuance of operating partnership units and the assumption or placement of secured and/or unsecured debt.

During 2024, we have approximately $97.6 million of secured debt maturing, inclusive of principal amortization, and $423.7 million of unsecured debt maturing. We anticipate repaying the debt due in 2024 with cash 43

During 2023, we incurred gross interest costs of $191.0 million, of which $10.1 million was capitalized.

We do not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources that are material.

Guarantor Subsidiary Summarized Financial Information

UDR has certain outstanding debt securities that are guaranteed by the Operating Partnership. With respect to this debt, as further outlined below, the Operating Partnership fully and unconditionally guarantees payment of any principal, premium and interest in full to the holders thereof. The Operating Partnership is a subsidiary of UDR, through which UDR conducts a significant portion of its business and holds a substantial amount of its assets. UDR also conducts business through other subsidiaries, including its taxable REIT subsidiaries. In addition to its ownership interest in the Operating Partnership, UDR holds interests in subsidiaries and joint ventures, owns and operates properties, issues securities from time to time and guarantees debt of certain of its subsidiaries. UDR, as the sole general partner of the Operating Partnership, owns 100 percent of the Operating Partnership’s general partnership interests and approximately 95 percent of its limited partnership interests and, by virtue thereof, has the ability to control all of the day-to-day operations of the Operating Partnership. UDR has concluded that it is the primary beneficiary of, and therefore consolidates, the Operating Partnership.

The Operating Partnership is the subsidiary guarantor of certain of our registered debt securities, including the $300 million of medium-term notes due September 2026, $300 million of medium-term notes due July 2027, $300 million of medium-term notes due January 2028, $300 million of medium-term notes due January 2029, $600 million of medium-term notes due January 2030, $600 million of medium-term notes due August 2031, $400 million of medium-term notes due August 2032, $350 million of medium-term notes due March 2033, $300 million of medium-term notes due in June 2033 and $300 million of medium-term notes due November 2034.

The Operating Partnership fully and unconditionally guarantees payment of any principal, premium and interest in full to the holders of the notes described above. The guarantee forms part of the indenture under which the notes were issued. If, for any reason, we do not make any required payment in respect of the notes when due, the Operating Partnership will cause the payment to be made to, or to the order of, the applicable paying agent on behalf of the trustee. Holders of the notes may enforce their rights under the guarantee directly against the Operating Partnership without first making a demand or taking action against UDR or any other person or entity. The Operating Partnership may, without the consent of the holders of the notes, assume all of our rights and obligations under the notes and, upon such assumption, we will be released from our liabilities under the indenture and the notes. 44

Table of Contents ​

The notes are UDR’s unsecured general obligations and rank equally with all of UDR’s other unsecured and unsubordinated indebtedness outstanding from time to time. As a result, our payment of amounts due on the notes is subordinated to all of our existing and future secured obligations to the extent of the value of the collateral pledged toward any such secured obligation. Our payment of amounts due on the notes also is effectively subordinated to all liabilities, whether secured or unsecured, of any of our non-guarantor subsidiaries because, in the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding with respect to such subsidiaries, we, as an equity holder of such subsidiaries, would not receive distributions from such subsidiaries until claims of any creditors of such subsidiaries are satisfied.

The following tables present the summarized financial information for the Operating Partnership as of December 31, 2023 and 2022, and for the years ended December 31, 2023, 2022, and 2021.

Statements of Cash Flows

The following discussion explains the changes in Net cash provided by/(used in) operating activities, Net cash provided by/(used in) investing activities, and Net cash provided by/(used in) financing activities that are presented in our Consolidated Statements of Cash Flows for the years ended December 31, 2023 and 2022.

Operating Activities

For the year ended December 31, 2023, our Net cash provided by/(used in) operating activities was $832.7 million compared to $820.1 million for 2022. The increase in cash flow from operating activities was primarily due to an increase in net operating income (“NOI”), primarily driven by higher revenue per occupied home, and NOI from additional operating communities, partially offset by a decrease in operating distributions from our unconsolidated joint ventures and changes in operating assets and liabilities. 45

Table of Contents Investing Activities

For the year ended December 31, 2023, Net cash provided by/(used in) investing activities was $(289.1) million compared to $(929.5) million for 2022. The decrease in cash used in investing activities was primarily due to a decrease in acquisitions, an increase in proceeds from sales of real estate, a decrease in spend for development of real estate assets, and a decrease in cash investments in unconsolidated joint ventures, partially offset by an increase in spend for capital expenditures and a decrease in distributions received from unconsolidated joint ventures and partnerships.

Acquisitions

In February 2023, the Company took title to a 136 apartment home operating community located in San Francisco, California, through a foreclosure proceeding. The community was previously owned by a consolidated joint venture of the Company. (See Note 5, Joint Ventures and Partnerships for more information).

In August 2023, the Company acquired a portfolio of six operating communities totaling 1,753 apartment homes, which included four operating communities in Dallas, Texas and two operating communities in Austin, Texas, for a purchase price of $354.6 million. The Company acquired the portfolio with a combination of cash, the assumption of six mortgage loans with an outstanding principal balance of approximately $209.4 million (fair value of $191.7 million), and the issuance of 3.6 million OP Units to the seller valued at $141.4 million. The OP Units were valued based on the closing price per share of UDR’s common stock on the date of acquisition in accordance with GAAP. The Company increased its real estate assets owned by approximately $344.8 million, recorded $9.8 million of in-place lease intangibles, and recorded a $17.6 million debt discount in connection with the below-market debt assumed.

In April 2022, the Company acquired a to-be-developed parcel of land located in Fort Lauderdale, Florida for approximately $16.0 million.

In June 2022, the Company acquired a 433 apartment home operating community located in Danvers, Massachusetts for approximately $207.5 million. The Company increased its real estate assets owned by approximately $203.7 million and recorded $3.8 million of in-place lease intangibles.

In June 2022, the Company acquired three contiguous to-be-developed parcels of land located in Dallas, Texas for approximately $90.2 million.

In June 2022, the Company acquired a to-be-developed parcel of land, which included two operating retail components, located in Riverside, California for approximately $29.0 million. The Company increased its real estate assets owned by approximately $28.2 million and recorded $0.8 million of in-place lease intangibles.

Dispositions

In January 2023, the Company sold the retail component of a development community located in Washington D.C. for gross proceeds of approximately $14.4 million, resulting in a gain of less than $0.1 million. The gross proceeds were received ratably throughout the development of the community and are reflected as a reduction of capital expenditures.

In June 2023, the Company contributed four wholly owned operating communities, totaling 1,328 apartment homes located in various markets, to a newly formed joint venture in exchange for a 51.0% interest in the venture. The contribution resulted in the Company no longer retaining a controlling interest in the communities, and the Company deconsolidated the operating communities. The Company received approximately $247.9 million in cash proceeds from our joint venture partner at formation. The transaction was accounted for as a partial sale and resulted in a gain of approximately $325.9 million, which was recorded in Gain/(loss) on sale of real estate owned on the Consolidated Statement of Operations, which consisted of the gain on the partial sale and the initial measurement of our retained interest at fair value. (See Note 5, Joint Ventures and Partnerships for further discussion.)

In December 2023, the Company sold an operating community located in Hillsboro, Oregon with a total of 276 apartment homes for gross proceeds of $78.6 million, resulting in a gain of approximately $25.3 million.

In November 2022, the Company sold an operating community located in Orange County, California with a total of 90 apartment homes for gross proceeds of $41.5 million, resulting in a gain of approximately $25.5 million.

Table of Contents We plan to continue to pursue our strategy of exiting markets where long-term growth prospects are limited and redeploying capital to primary locations in markets we believe will provide the best investment returns.

Capital Expenditures

We capitalize those expenditures that materially enhance the value of an existing asset or substantially extend the useful life of an existing asset. Expenditures necessary to maintain an existing property in ordinary operating condition are expensed as incurred.

For the year ended December 31, 2023, total capital expenditures of $303.7 million or $5,567 per stabilized home, which in aggregate include recurring capital expenditures and major renovations, were spent across our portfolio, excluding development, as compared to $234.0 million or $4,373 per stabilized home for the prior year.

The increase in total capital expenditures was primarily due to:

an increase of 46.7%, or $39.3 million, in major renovations, which includes major structural changes and/or architectural revisions to existing buildings;
an increase of 25.6%, or $18.5 million, in NOI enhancing improvements, such as kitchen and bath remodels and upgrades to common areas; and
--- ---
an increase of 15.9%, or $11.8 million, in recurring capital expenditures, which includes asset preservation and turnover-related expenditures.
--- ---

The following table outlines capital expenditures and repair and maintenance costs for all of our communities, excluding real estate under development, for the years ended December 31, 2023 and 2022 (dollars in thousands except Per Home amounts):

Average home count (d) **** 54,476 **** 53,514 1.8 %
(a) NOI enhancing improvements are expenditures that result in increased income generation or decreased expense growth.
--- ---
(b) Major renovations include major structural changes and/or architectural revisions to existing buildings.
--- ---
(c) Total capital expenditures includes amounts capitalized during the year. Cash paid for capital expenditures is impacted by the net change in related accruals.
--- ---
(d) Average number of homes is calculated based on the number of homes outstanding at the end of each month.
--- ---

We intend to continue to selectively add NOI enhancing improvements, which we believe will provide a return on investment in excess of our cost of capital. Our objective in redeveloping a community is twofold: we aim to meaningfully grow rental rates while also achieving cap rate compression through asset quality improvement.

Consolidated Real Estate Under Development and Redevelopment

At December 31, 2023, our development pipeline consisted of two wholly-owned communities located in Addison, Texas and Tampa, Florida, totaling 415 homes, of which 56 have been completed, with a budget of $187.5 million, in which we have a gross carrying value of $160.4 million. The communities are estimated to be completed in the second quarter of 2024. During 2023, we incurred $159.3 million for development costs, a decrease of $38.7 million as compared to costs incurred in 2022 of $198.0 million. 47

Table of Contents At December 31, 2023, the Company had no communities at which it was conducting substantial redevelopment activities.

Unconsolidated Joint Ventures and Partnerships

The Company recognizes income or losses from our investments in unconsolidated joint ventures and partnerships consisting of our proportionate share of the net income or losses of the joint ventures and partnerships. In addition, we may earn fees for providing management services to the communities held by the unconsolidated joint ventures and partnerships.

The Company’s Investment in and advances to unconsolidated joint ventures and partnerships, net, are accounted for under the equity method of accounting. For the year ended December 31, 2023:

we made cash investments totaling $71.4 million in our unconsolidated joint ventures and partnerships;
our proportionate share of the net income/(loss) of the joint ventures and partnerships was $4.7 million, which included a $24.3 million loss due to the consolidation of one of our preferred equity investment joint venture (described below); and
--- ---
we received cash distributions of $30.3 million, of which $15.9 million were operating cash flows and $14.4 million were investing cash flows.
--- ---

We evaluate our investments in unconsolidated joint ventures and partnerships when events or changes in circumstances indicate that there may be an other-than-temporary decline in value. We consider various factors to determine if a decrease in the value of the investment is other-than-temporary. The Company did not recognize any other-than-temporary impairments in the value of its investments in unconsolidated joint ventures or partnerships during the years ended December 31, 2023 and 2022.

Financing Activities

For the years ended December 31, 2023 and 2022, Net cash provided by/(used in) financing activities was $(538.9) million and $111.2 million, respectively.

The following significant financing activities occurred during the year ended December 31, 2023:

repurchased 0.6 million shares of common stock at an average price of $40.13 per share for approximately $25.0 million;
received net proceeds of $108.1 million on our unsecured commercial paper program;

Table of Contents Credit Facilities and Commercial Paper Program

The Company has a $1.3 billion unsecured revolving credit facility (the “Revolving Credit Facility”) and a $350.0 million unsecured term loan (the “Term Loan”). The credit agreement for these facilities ( the “Credit Agreement”) allows the total commitments under the Revolving Credit Facility and the total borrowings under the Term Loan to be increased to an aggregate maximum amount of up to $2.5 billion, subject to certain conditions, including obtaining commitments from one or more lenders. The Revolving Credit Facility has a scheduled maturity date of January 31, 2026, with two six-month extension options, subject to certain conditions. The Term Loan has a scheduled maturity date of January 31, 2027.

Based on the Company’s current credit rating, the Revolving Credit Facility has an interest rate equal to Adjusted SOFR plus a margin of 75.5 basis points and a facility fee of 15 basis points, and the Term Loan has an interest rate equal to Adjusted SOFR plus a margin of 83.0 basis points. Depending on the Company’s credit rating, the margin under the Revolving Credit Facility ranges from 70 to 140 basis points, the facility fee ranges from 10 to 30 basis points, and the margin under the Term Loan ranges from 75 to 160 basis points. Further, the Credit Agreement includes sustainability adjustments pursuant to which the applicable margin for the Revolving Credit Facility and the Term Loan were reduced by **** two **** basis points upon the Company receiving certain green building certifications, which is reflected in the margins noted above.

As of December 31, 2023, we had no outstanding borrowings under the Revolving Credit Facility, leaving $1.3 billion of unused capacity (excluding $2.3 million of letters of credit at December 31, 2023), and $350.0 million of outstanding borrowings under the Term Loan.

The Company has a working capital credit facility, which provides for a $75.0 million unsecured revolving credit facility (the “Working Capital Credit Facility”) with a scheduled maturity date of January 12, 2025. In November 2023, the Company amended the Working Capital Credit Facility to extend the maturity date from January 12, 2024 to January 12, 2025, plus a one-year extension option. Based on the Company’s current credit rating, the Working Capital Credit Facility has an interest rate equal to Adjusted SOFR plus a margin of 77.5 basis points. Depending on the Company’s credit rating, the margin ranges from 70 to 140 basis points.

As of December 31, 2023, we had $4.6 million of outstanding borrowings under the Working Capital Credit Facility, leaving $70.4 million of unused capacity.

The bank revolving credit facilities and the term loan are subject to customary financial covenants and limitations, all of which we were in compliance with at December 31, 2023.

The Company has an unsecured commercial paper program. Under the terms of the program, the Company may issue unsecured commercial paper up to a maximum aggregate amount outstanding of $700.0 million. The notes are sold under customary terms in the United States commercial paper market and rank pari passu with all of the Company’s other unsecured indebtedness. The notes are fully and unconditionally guaranteed by the Operating Partnership. As of December 31, 2023, we had issued $408.1 million of commercial paper, for one month terms, at a weighted average annualized rate of 5.7%, leaving $291.9 million of unused capacity.

Interest Rate Risk

We are exposed to interest rate risk associated with variable rate notes payable and maturing debt that has to be refinanced. We do not hold financial instruments for trading or other speculative purposes, but rather issue these financial instruments to finance our portfolio of real estate assets and operations. Interest rate sensitivity is the relationship between changes in market interest rates and the fair value of market rate sensitive assets and liabilities. Our earnings are affected as changes in short-term interest rates impact our cost of variable rate debt and maturing fixed rate debt. We had $479.7 million in variable rate debt that is not subject to interest rate swap contracts as of December 31, 2023. If market interest rates for variable rate debt increased by 100 basis points, our interest expense would increase by $5.0 million based on the average balance outstanding during the year.

These amounts are determined by considering the impact of hypothetical interest rates on our borrowing cost. This analysis does not consider the effects of the adjusted level of overall economic activity that could exist in such an environment or actions we may take to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no change in our financial structure. 49

Table of Contents The Company also utilizes derivative financial instruments to manage interest rate risk and generally designates these financial instruments as cash flow hedges. See Note 14, Derivatives and Hedging Activities, in the Notes to the UDR Consolidated Financial Statements included in this Report for additional discussion of derivative instruments.

A presentation of cash flow metrics based on GAAP is as follows (dollars in thousands):

Results of Operations

The following discussion explains the changes in results of operations that are presented in our Consolidated Statements of Operations for the years ended December 31, 2023 and 2022.

Net Income/(Loss) Attributable to Common Stockholders

Net income/(loss) attributable to common stockholders was $439.5 million ($1.34 per diluted share) for the year ended December 31, 2023, as compared to $82.5 million ($0.26 per diluted share) for the prior year. The increase resulted primarily from the following items, all of which are discussed in further detail elsewhere within this Report:

gains on the sale of real estate of $351.2 million from the partial sale of four operating communities located in various markets and the sale of an operating community located in Hillsboro, Oregon, during the year ended December 31, 2023, as compared to a gain of $25.5 million from the sale of one operating community located in Orange County, California, during the year ended December 31, 2022;
an increase in total property NOI of $74.4 million primarily due to higher revenue per occupied home and NOI from additional operating communities, partially offset by a decrease in weighted average physical occupancy and an increase in property operating expenses; and
--- ---
an increase in interest income and other income/(expense), net of $24.7 million primarily due to realized and unrealized gains/(losses) of $3.5 million from our direct investment in SmartRent during the year ended December 31, 2023, as compared to $(15.7) million during the year ended December 31, 2022, and $11.0 million of higher interest income from our notes receivables, partially offset by a $5.9 million gain from the sale of a technology investment in 2022.

This was partially offset by:

an increase in net income attributable to redeemable noncontrolling interests in the Operating Partnership and DownREIT Partnership of $24.5 million primarily attributed to the noncontrolling interests’ share of the gain from the partial sale of four operating communities located in various markets and an operating community located in Hillsboro, Oregon during the year ended December 31, 2023, as compared to the noncontrolling interests’ share of the gain from the sale of an operating community located in Orange County, California during the year ended December 31, 2022;

Table of Contents Apartment Community Operations

Our net income results are primarily from NOI generated from the operation of our apartment communities. The Company defines NOI, which is a non-GAAP financial measure, as rental income less direct property rental expenses. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. Rental expenses include real estate taxes, insurance, personnel, utilities, repairs and maintenance, administrative and marketing. Excluded from NOI is property management expense, which is calculated as 3.25% of property revenue, and land rent. Property management expense covers costs directly related to consolidated property operations, inclusive of corporate management, regional supervision, accounting and other costs.

Management considers NOI a useful metric for investors as it is a more meaningful representation of a community’s continuing operating performance than net income as it is prior to corporate-level expense allocations, general and administrative costs, capital structure and depreciation and amortization.

Although the Company considers NOI a useful measure of operating performance, NOI should not be considered an alternative to net income or net cash flow from operating activities as determined in accordance with GAAP. NOI excludes several income and expense categories as detailed in the reconciliation of NOI to Net income/(loss) attributable to UDR, Inc. below.

The following table summarizes the operating performance of our total property NOI for each of the periods presented (dollars in thousands):

Same-Store Communities

Our Same-Store Community properties (those acquired, developed, and stabilized prior to January 1, 2022 and held on December 31, 2023) consisted of 51,368 apartment homes and provided 93.1% of our total NOI for the year ended December 31, 2023.

NOI for our Same-Store Community properties increased 6.0%, or $58.8 million, for the year ended December 31, 2023 compared to the same period in 2022. The increase in property NOI was attributable to a 5.6%, or $79.3 million, increase in property rental income, which was partially offset by a 4.7%, or $20.5 million, increase in operating expenses. The increase in property rental income was primarily driven by a 6.1%, or $80.9 million, increase in rental rates, and a 6.4%, or $9.7 million, increase in reimbursement and ancillary and fee income, partially offset by a $4.9 million increase in bad debt based on probability of collection and a $3.4 million impact from higher concessions. Weighted average physical occupancy decreased by 0.1% to 96.7% and total monthly income per occupied home increased 5.7% to $2,501.

The increase in operating expenses was primarily driven by a 10.3%, or $8.3 million, increase in repair and maintenance expense due to an increase in the cost per home of those that were turned during the year, the impact of inflation on third party vendor costs, and weather-related events, a 10.6%, or $6.2 million, increase in utilities, which was primarily due an increase in energy costs, a 3.2%, or $5.7 million, increase in real estate taxes due to higher assessed valuations, and a 6.9%, or $2.0 million, increase in administrative and marketing expense, partially offset by a $2.5 million decrease in insurance expense primarily due to a decrease in the impact from claims.

The operating margin (property net operating income divided by property rental income) was 69.6% and 69.3% for the years ended December 31, 2023 and 2022, respectively.

Non-Mature Communities/Other

UDR’s Non-Mature Communities/Other represent those communities that do not meet the criteria to be included in Same-Store Communities, which include communities recently developed or acquired, redevelopment properties, sold or held for disposition properties, and non-apartment components of mixed use properties.

The remaining 6.9%, or $77.1 million, of our total NOI during the year ended December 31, 2023 was generated from our Non-Mature Communities/Other. NOI from Non-Mature Communities/Other increased by 25.3%, or $15.6 million, for the year ended December 31, 2023 as compared to the same period in 2022. The increase was primarily attributable to a $17.1 million increase in NOI from stabilized, non-mature communities, primarily due to development communities completed in 2023 and 2022 and becoming stabilized, and a $3.5 million increase in non- 52

Table of Contents residential/other NOI due to changes in straight-line rent as a result of a decrease in tenant rent concessions during 2023, partially offset by a $6.7 million decrease in sold and held for disposition communities NOI due to the partial sale of four operating communities and the sale of one operating community in 2023, and one operating community held for disposition at December 31, 2023, as compared to the sale of one operating community in 2022.

Real estate depreciation and amortization

For the years ended December 31, 2023 and 2022, the Company recognized real estate depreciation and amortization of $676.4 million and $665.2 million, respectively. The increase in 2023 as compared to 2022 was primarily due to communities acquired and completions of developments in 2023 and 2022, partially offset by communities sold in 2023 and assets that became fully depreciated in 2023 and 2022.

Gain/(Loss) on Sale of Real Estate Owned

During the year ended December 31, 2023, the Company recognized a gain of $351.2 million from the partial sale of four operating communities located in various markets and the sale of an operating community located in Hillsboro, Oregon.

During the year ended December 31, 2022, the Company recognized a gain of $25.5 million from the sale of one operating community located in Orange County, California.

Income/(Loss) from Unconsolidated Entities

During the year ended December 31, 2023, the Company recognized income/(loss) from unconsolidated entities of $4.7 million, which was primarily due to net income from our operating joint ventures and preferred equity investments, partially offset by a $24.3 million loss on consolidation of one of our preferred equity investments.

During the year ended December 31, 2022, the Company recognized income/(loss) from unconsolidated entities of $4.9 million, which was primarily due to net income from our operating joint ventures and preferred equity investments and $10.6 million of net variable upside participation recorded on the sale of a DCP community, partially offset by $(35.5) million of investment income/(loss) from RETV I, which primarily related to unrealized gains/(losses) from one portfolio investment held by RETV I, SmartRent.

Interest expense

For the years ended December 31, 2023 and 2022, the Company recognized interest expense of $180.9 million and $155.9 million, respectively. The increase in 2023 as compared to 2022 was primarily due to an increase in average interest rates and higher overall debt balances during the year ended December 31, 2023 as compared to 2022.

Interest income and other income/(expense), net

For the years ended December 31, 2023 and 2022, the Company recognized interest income and other income/(expense), net of $17.8 million and $(6.9) million, respectively. The increase of $24.7 million was primarily due to realized and unrealized gains/(losses) of $3.5 million from our direct investment in SmartRent during the year ended December 31, 2023, as compared to $(15.7) million during the year ended December 31, 2022, and $11.0 million of higher interest income from our notes receivables, partially offset by a $5.9 million gain from the sale of a technology investment in 2022.

Noncontrolling Interest

For the years ended December 31, 2023 and 2022, the Company recognized net income attributable to redeemable noncontrolling interests in the Operating Partnership and DownREIT Partnership of $30.1 million and $5.6 million, respectively. The increase in 2023 as compared to 2022 was primarily attributed to the noncontrolling interests’ share of the gains from the partial sale of four operating communities located in various markets and a gain form the sale of an operating community located in Hillsboro, Oregon during the year ended December 31, 2023, as compared to the noncontrolling interests’ share of a gain from the sale of an operating community in Orange County, California during the year ended December 31, 2022.

Inflation 53

Table of Contents Inflation primarily impacts our results of operations as a result of wage pressures and increases in utilities and repair and maintenance costs. In addition, inflation could also impact our general and administrative expenses, the interest on our debt if variable or refinanced in a high-inflationary environment, our cost of capital, and our cost of development, redevelopment, maintenance or other operating activities. However, the majority of our apartment leases have initial terms of 12 months or less, which in an inflationary environment, and absent other factors such as increased supply, generally enables us to compensate for inflationary effects by increasing rents on our apartment homes. Although an extreme or sustained escalation in costs could have a negative impact on our residents and their ability to absorb rent increases, we do not believe this had a material impact on our results for the year ended December 31, 2023.

Funds from Operations, Funds from Operations as Adjusted, and Adjusted Funds from Operations

Funds from Operations

Funds from operations (“FFO”) attributable to common stockholders and unitholders is defined as Net income/(loss) attributable to common stockholders (computed in accordance with GAAP), excluding impairment write-downs of depreciable real estate related to the main business of the Company or of investments in non-consolidated investees that are directly attributable to decreases in the fair value of depreciable real estate held by the investee, gains and losses from sales of depreciable real estate related to the main business of the Company and income taxes directly associated with those gains and losses, plus real estate depreciation and amortization, and after adjustments for noncontrolling interests, and the Company’s share of unconsolidated partnerships and joint ventures. This definition conforms with the National Association of Real Estate Investment Trust’s (“Nareit”) definition issued in April 2002 and restated in November 2018. Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry investors and analysts have considered the presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Thus, Nareit created FFO as a supplemental measure of a REIT’s operating performance. In the computation of diluted FFO, if OP Units, DownREIT Units, unvested restricted stock, unvested LTIP Units, stock options, and the shares of Series E Cumulative Convertible Preferred Stock are dilutive, they are included in the diluted share count.

Management considers FFO a useful metric for investors as the Company uses FFO in evaluating property acquisitions and its operating performance, and believes that FFO should be considered along with, but not as an alternative to, net income and cash flow as a measure of the Company’s activities in accordance with GAAP. FFO does not represent cash generated from operating activities in accordance with GAAP and is not necessarily indicative of funds available to fund our cash needs.

Funds from Operations as Adjusted

FFO as Adjusted (“FFOA”) attributable to common stockholders and unitholders is defined as FFO excluding the impact of non-comparable items including, but not limited to, acquisition-related costs, prepayment costs/benefits associated with early debt retirement, impairment write-downs or gains and losses on sales of real estate or other assets incidental to the main business of the Company and income taxes directly associated with those gains and losses, casualty-related expenses and recoveries, severance costs and legal and other costs.

Management believes that FFOA is useful supplemental information regarding our operating performance as it provides a consistent comparison of our operating performance across time periods and enables investors to more easily compare our operating results with other REITs. FFOA is not intended to represent cash flow or liquidity for the period, and is only intended to provide an additional measure of our operating performance. We believe that Net income/(loss) attributable to common stockholders is the most directly comparable GAAP financial measure to FFOA. However, other REITs may use different methodologies for calculating FFOA or similar FFO measures and, accordingly, our FFOA may not always be comparable to FFOA or similar FFO measures calculated by other REITs. FFOA should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or as an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity.

Adjusted Funds from Operations

Adjusted FFO (“AFFO”) attributable to common stockholders and unitholders is defined as FFOA less recurring capital expenditures on consolidated communities that are necessary to help preserve the value of and maintain 54

Table of Contents functionality at our communities. Therefore, management considers AFFO a useful supplemental performance metric for investors as it is more indicative of the Company’s operational performance than FFO or FFOA.

AFFO is not intended to represent cash flow or liquidity for the period, and is only intended to provide an additional measure of our operating performance. We believe that Net income/(loss) attributable to common stockholders is the most directly comparable GAAP financial measure to AFFO. Management believes that AFFO is a widely recognized measure of the operations of REITs, and presenting AFFO enables investors to assess our performance in comparison to other REITs. However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not always be comparable to AFFO calculated by other REITs. AFFO should not be considered as an alternative to net income/(loss) (determined in accordance with GAAP) as an indication of financial performance, or as an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

To the Stockholders and the Board of Directors of UDR, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of UDR, Inc. (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income/(loss), changes in equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and the financial statement schedule listed in the Index at Item 15(a)^^(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

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

Basis for Opinion

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

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

Critical Audit Matters

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

Indicators of Impairment of Real Estate Owned and Investment in Unconsolidated Joint Ventures
Description of the Matter At December 31, 2023, the Company’s real estate owned, net and investment in and advances to unconsolidated joint ventures, net were approximately $9.8 billion and $952.9 million, respectively. As more fully described in Note 2 to the consolidated financial statements, the Company periodically evaluates these assets for indicators of impairment, and this includes, among other things, judgments based on factors such as operational performance, market conditions, the Company’s intent and ability to hold each asset, as well as any significant cost overruns on development or redevelopment communities. During 2023, the Company did not recognize an impairment related to real estate

owned, net or any other than temporary impairments related to its investment in unconsolidated joint ventures.<br><br>Auditing the Company’s evaluation for indicators of impairment was complex due to a high degree of subjectivity in the identification of events or changes in circumstances that may indicate an impairment of its real estate owned or that the value of its investment in unconsolidated joint ventures may be other than temporarily impaired. Differences or changes in these judgments could have a material impact on the Company’s analysis.
How We Addressed the Matter in Our Audit We tested the Company’s internal controls over the asset impairment evaluation process. This included testing controls over management’s determination and review of the considerations used in the impairment indicator analysis.<br><br>Our procedures with regards to the Company’s evaluation for indicators of impairment included, among others, testing the completeness and accuracy of management’s impairment analysis and evaluating management’s judgments determining whether indicators of impairment were present. For example, we performed inquires of management, considered historical operating results and the current market conditions, performed an independent assessment using both internally and externally available information, read the minutes of the meetings of the Board of Directors, and reviewed the Company’s development and redevelopment costs.
Accounting for acquisitions of real estate investment properties
Description of the Matter During 2023, the Company acquired real estate investment properties which were accounted for as asset acquisitions. The aggregate increase in real estate and other assets due to these acquisitions was approximately $354.6 million. As more fully described in Note 3 to the consolidated financial statements, the total consideration was allocated to land, land improvements, buildings and improvements, and real estate intangible assets based on their relative fair value.<br><br>Auditing the Company’s acquisition of real estate investment properties is complex and requires a higher degree of auditor judgment due to the significant assumptions that are utilized in the determination of the relative fair values of the assets acquired. The significant assumptions used in management’s analysis to estimate the fair value of these components includes capitalization rates, market comparable prices for similar land parcels, and market rental rates.
How We Addressed the Matter in Our Audit We tested the Company’s internal controls over the acquisition of real estate investment properties and the resulting purchase price allocations. This included testing controls over management’s identification of the assets acquired and liabilities assumed and evaluating the methods and significant assumptions used by the Company to develop such estimates.<br><br>Our testing of the fair values of the assets acquired included, among others, evaluating the selection of the Company's valuation model and testing the significant assumptions discussed above as well as the completeness and accuracy of the underlying data. For example, we compared management’s assumptions to observable market transactions and replacement costs associated with the fair value of the land and buildings and improvements. We involved our real estate valuation specialists to assist in evaluating the significant assumptions listed above. In addition, we performed sensitivity tests on the significant assumptions to evaluate the change in the fair value resulting from changes in the assumptions.

To the Stockholders and the Board of Directors of UDR, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited UDR, Inc.’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) **** (the COSO criteria). In our opinion, UDR, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income/(loss), changes in equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes, and the financial statement schedule listed in the accompanying Index at Item 15(a) and our report dated February 20, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

  1. CONSOLIDATION AND BASIS OF PRESENTATION

Organization and Formation

UDR, Inc. (“UDR,” the “Company,” “we,” or “our”) is a self-administered real estate investment trust, or REIT, that owns, operates, acquires, renovates, develops, redevelops, and manages apartment communities in targeted markets located in the United States. At December 31, 2023, our consolidated apartment portfolio consisted of 168 communities with a total of 55,550 apartment homes located in 21 markets. In addition, the Company has an ownership interest in 10,045 completed or to-be-completed apartment homes through unconsolidated joint ventures or partnerships, including 5,618 apartment homes owned by entities in which we hold preferred equity investments.

Basis of Presentation

The accompanying consolidated financial statements of UDR include its wholly-owned and/or controlled subsidiaries (see Note 4, Variable Interest Entities and Note 5, Joint Ventures and Partnerships, for further discussion). All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying consolidated financial statements include the accounts of UDR and its subsidiaries, including United Dominion Realty, L.P. (the “Operating Partnership” or the “OP”) and UDR Lighthouse DownREIT L.P. (the “DownREIT Partnership”). As of December 31, 2023 and 2022, there were 189.9 million and 186.1 million units, respectively, in the Operating Partnership (“OP Units”) outstanding, of which 176.4 million, or 92.9% and 176.3 million, or 94.7%, respectively, were owned by UDR and 13.5 million, or 7.1% and 9.8 million, or 5.3%, respectively, were owned by outside limited partners. As of December 31, 2023 and 2022, there were 32.4 million units in the DownREIT Partnership (“DownREIT Units”) outstanding, of which 21.4 million, or 66.0% and 21.1 million, or 65.1%, respectively, were owned by UDR and its subsidiaries and 11.0 million, or 34.0% and 11.3 million, or 34.9%, respectively, were owned by outside limited partners. The consolidated financial statements of UDR include the noncontrolling interests of the unitholders in the Operating Partnership and DownREIT Partnership.

The Company evaluated subsequent events through the date its financial statements were issued. No significant recognized or non-recognized subsequent events were noted other than those in Note 3, Real Estate Owned and Note 5, Joint Ventures and Partnerships.

  1. SIGNIFICANT ACCOUNTING POLICIES

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which requires disclosure enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. The ASU is effective for the Company for the year ended December 31, 2025. The Company is currently evaluating the effect that the ASU will have on the consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07*,* Segment Reporting (Topic 280) – Improvements to Reportable Segments Disclosures. ASU 2023-07 requires expanded disclosures of a public entity’s reportable segments, and requires more enhanced information regarding a reportable segment’s expenses on an interim and annual basis. The ASU is effective for the Company for the year ended December 31, 2024, and interim periods commencing in 2025. Early adoption is permitted. The Company is currently evaluating the effect that the ASU will have on the consolidated financial statements and related disclosures.

Real Estate

Real estate assets held for investment are carried at historical cost and consist of land, land improvements, buildings and improvements, furniture, fixtures and equipment and other costs incurred during their development, acquisition and redevelopment.

F - 11

UDR, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

Expenditures for ordinary repair and maintenance costs are charged to expense as incurred. Expenditures for improvements, renovations, and replacements related to the acquisition and/or improvement of real estate assets are capitalized and depreciated over their estimated useful lives if the expenditures qualify as a betterment or the life of the related asset will be substantially extended beyond the original life expectancy.

UDR purchases real estate investment properties and records the tangible and identifiable intangible assets and liabilities acquired based on their estimated fair value. The primary, although not only, identifiable intangible asset associated with our portfolio is the value of existing lease agreements. When recording the acquisition of a community, we first assign fair value to the estimated intangible value of the existing lease agreements and then to the estimated value of the land, building and fixtures assuming the community is vacant. The Company estimates the intangible value of the lease agreements by determining the lost revenue associated with a hypothetical lease-up. Depreciation on the building is based on the expected useful life of the asset and the in-place leases are amortized over their remaining average contractual life. Property acquisition costs are capitalized as incurred if the acquisition does not meet the definition of a business.

Quarterly or when changes in circumstances warrant, UDR will assess our real estate properties for indicators of impairment. The judgments regarding the existence of impairment indicators are based on certain factors. Such factors include, among other things, operational performance, market conditions, the Company’s intent and ability to hold the related asset, as well as any significant cost overruns on development properties.

If a real estate property has indicators of impairment, we assess whether the long-lived asset’s carrying value exceeds the community’s undiscounted future cash flows, which is representative of projected net operating income (“NOI”) plus the residual value of the community. Our future cash flow estimates are based upon historical results adjusted to reflect our best estimate of future market and operating conditions and our estimated holding periods. If such indicators of impairment are present and the carrying value exceeds the undiscounted cash flows of the community, an impairment loss is recognized equal to the excess of the carrying amount of the asset over its estimated fair value. Our estimates of fair value represent our best estimate based primarily upon unobservable inputs related to rental rates, operating costs, growth rates, discount rates, capitalization rates, industry trends and reference to market rates and transactions.

For long-lived assets to be disposed of, impairment losses are recognized when the fair value of the asset less estimated cost to sell is less than the carrying value of the asset. Properties classified as real estate held for disposition generally represent properties that are actively marketed or contracted for sale with the closing expected to occur within the next twelve months. Real estate held for disposition is carried at the lower of cost, net of accumulated depreciation, or fair value, less the cost to sell, determined on an asset-by-asset basis. Expenditures for ordinary repair and maintenance costs on held for disposition properties are charged to expense as incurred. Expenditures for improvements, renovations, and replacements related to held for disposition properties are capitalized at cost. Depreciation is not recorded on real estate held for disposition.

For the years ended December 31, 2023, 2022 and 2021, we did not record any impairments on our real estate properties.

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets which are 30 to 55 years for buildings, 10 to 35 years for major improvements, and 3 to 10 years for furniture, fixtures, equipment, and other assets.

Predevelopment, development, and redevelopment projects and related costs are capitalized and reported on the Consolidated Balance Sheets as Total real estate owned, net of accumulated depreciation. The Company capitalizes costs directly related to the predevelopment, development, and redevelopment of a capital project, which include, but are not limited to, interest, real estate taxes, insurance, and allocated development and redevelopment overhead related to support costs for personnel working on the capital projects. We use our professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. These costs are capitalized only during the period in which activities necessary to ready an asset for its intended use are in progress and such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. These costs, excluding the direct costs of development and redevelopment and capitalized interest, for the years ended December 31, 2023, 2022, and 2021 were $13.1 million, $17.9 million and $11.3 million, respectively. During the years ended December 31, 2023, F - 12

2022, and 2021, total interest capitalized was $10.1 million, $13.4 million and $9.7 million, respectively. As each home in a capital project is completed and becomes available for lease-up, the Company ceases capitalization on the related portion and depreciation commences over the estimated useful life.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand, demand deposits with financial institutions and short-term, highly liquid investments. We consider all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. The majority of the Company’s cash and cash equivalents are held at major commercial banks.

Restricted Cash

Restricted cash primarily consists of escrow deposits held by lenders for real estate taxes, insurance and replacement reserves, and security deposits.

Real Estate Sales Gain Recognition

For sale transactions resulting in a transfer of a controlling financial interest of a property, the Company generally derecognizes the related assets and liabilities from its Consolidated Balance Sheets and records the gain or loss in the period in which the transfer of control occurs. If control of the property has not been transferred by the Company, the criteria for derecognition are not met and the Company will continue to recognize the related assets and liabilities on its Consolidated Balance Sheets.

Sale transactions to entities in which the Company sells a controlling financial interest in a property but retains a noncontrolling interest are accounted for as partial sales. Partial sales resulting in a change in control are accounted for at fair value and a full gain or loss is recognized. Therefore, the Company will record a gain or loss on the partial interest sold, and the initial measurement of our retained interest will be accounted for at fair value.

Sales of real estate to joint ventures or other noncontrolled investees are also accounted for at fair value and the Company will record a full gain or loss in the period the property is contributed.

To the extent that the Company acquires a controlling financial interest in a property that it previously accounted for as an equity method investment, the Company will not remeasure its previously held interest if the acquisition is treated as an asset acquisition. The Company will include the carrying amount of its previously held equity method interest along with the consideration paid and transaction costs incurred in determining the amounts to allocate to the related assets and liabilities acquired on its Consolidated Balance Sheets. When treated as an asset acquisition, the Company will not recognize a gain or loss on consolidation of a property.

Allowance for Credit Losses

The Company accounts for allowance for credit losses under the current expected credit loss (“CECL”) impairment model for its financial assets, including trade and other receivables, held-to-maturity debt securities, loans and other financial instruments, and presents the net amount of the financial instrument expected to be collected. The CECL impairment model excludes operating lease receivables. The CECL impairment model requires an estimate of expected credit losses, measured over the contractual life of an instrument, that considers forecasts of future economic conditions in addition to information about past events and current conditions. Based on this model, we analyze the following criteria, as applicable in developing allowances for credit losses: historical loss information, the borrower’s ability to make scheduled payments, the remaining time to maturity, the value of underlying collateral, projected future performance of the borrower and macroeconomic trends.

The Company measures credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. If the Company determines that a financial asset does not share risk characteristics with the Company’s other financial assets, the Company evaluates the financial asset for expected credit losses on an individual basis. Allowance for credit losses are recorded as a direct reduction from an asset’s amortized cost basis. Credit losses and recoveries are recorded inInterest income and other income/(expense), net on the Consolidated Statements of F - 13

Operations. Recoveries of financial assets previously written off are recorded when received. For the years ended December 31, 2023, 2022 and 2021, the Company recorded net credit recoveries/(losses) of $(0.7) million, $(0.1) million and $0.6 million, respectively, on the Consolidated Statements of Operations.

The Company has made the optional election provided by the standard not to measure allowance for credit losses for accrued interest receivables as the Company writes off any uncollectible accrued interest receivables in a timely manner. The Company periodically evaluates the collectability of its accrued interest receivables. A write-off is recorded when the Company concludes that all or a portion of its accrued interest receivable balance is no longer collectible.

Notes Receivable

Notes receivable relate to financing arrangements which are typically secured by assets of the borrower that may include real estate assets. Certain of the loans we extend may include characteristics such as options to purchase the project within a specific time window following expected project completion. These characteristics can cause the loans to fall under the definition of a variable interest entity (“VIE”), and thus trigger consolidation consideration. We consider the facts and circumstances pertinent to each loan, including the relative amount of financing we are contributing to the overall project cost, decision making rights or control we hold, and our rights to expected residual gains or our obligations to absorb expected residual losses from the project. If we are deemed to be the primary beneficiary of a VIE due to holding a controlling financial interest, the majority of decision making control, or by other means, consolidation of the VIE would be required. The Company has concluded that it is not the primary beneficiary of the borrowing entities of the existing loans.

Additionally, we analyze each loan arrangement that involves real estate development to consider whether the loan qualifies for accounting as a loan or as an investment in a real estate development project. The Company has evaluated its real estate loans, where appropriate, for accounting treatment as loans versus real estate development projects, as required by ASC 310-10. For each loan, the Company has concluded that the characteristics and the facts and circumstances indicate that loan accounting treatment is appropriate.

The following table summarizes our Notes receivable, net as of December 31, 2023 and 2022 (dollars in thousands):

(b) In June 2023, the Company amended the agreement for a preferred equity investment in a joint venture that owns a 471 apartment home operating community located in Philadelphia, Pennsylvania, which resulted in the Company’s investment, inclusive of accrued preferred return, being classified as a note receivable. In connection with the amendment, the Company also advanced $20.0 million to the joint venture, which is also classified as a note receivable (collectively the “Notes”) and was used to pay down the senior construction loan in connection with an extension of the maturity date of the senior construction loan to January 2024. Furthermore, the contractual interest rate on the Notes increased to 9.5% (previously 8.5%) in exchange for eliminating the Company’s upside participation in the joint venture. Interest payments accrue monthly and are due at maturity, but can be paid earlier. The Notes had an original scheduled maturity date in October 2023, with three one-year extension options. In September 2023, the developer extended the maturity date to October 2024. Commencing in October 2023, the

contractual interest rate on the Notes increased to 10.5% when the developer exercised its option to extend the maturity date of the Notes. (See Note 5, Joint Ventures and Partnerships for further discussion.) In January 2024, the joint venture extended the senior construction loan from January 2024 to April 2024.
(c) The Company has a secured note with an unaffiliated third party with an aggregate commitment of $32.5 million, of which $31.5 million was funded as of December 31, 2023. During 2023, the terms of this secured note were amended to increase the aggregate commitment from $31.4 million to $32.5 million and to increase the interest rate from 10.0% to 12.0%. Interest payments are due monthly, with the exception of payments from June 2022 to December 2024, which are accrued and added to the principal balance and will be due at maturity of the note. The additional amount accrued and added to the principal balance was $5.5 million as of December 31, 2023. The note is secured by substantially all of the borrower’s assets and matures at the earliest of the following: (a) the closing of any private or public capital raising in the amount of $5.0 million or greater; (b) an acquisition; (c) acceleration in the event of default; or (d) December 2024.

(e) The Company has a secured mezzanine loan with a third party developer of a 237 apartment home community located in Menifee, California, which is expected to be completed in 2025, with an aggregate commitment of $24.4 million (exclusive of accrued interest), of which $18.6 million was funded during the year ended December 31, 2023. Interest payments accrue for 36 months and are due monthly after the loan has been outstanding for 36 months. The secured mezzanine loan has a scheduled maturity date in December 2026, with two one-year extension options.

(f) The Company and a syndicate of lenders previously entered into a $16.0 million secured credit facility with an unaffiliated third party. During the year ended December 31, 2023, the secured credit facility was amended to provide a new term loan in the amount of $19.0 million, and increase the Company’s commitment from $1.5 million to $3.0 million (exclusive of accrued interest), all of which has been funded. Interest payments will accrue and be due at maturity of the facility. The facility is secured by substantially all of the borrower’s assets and matures at the earliest of the following: (a) acceleration in the event of default; or (b) June 2027.
--- ---

The Company recognized $14.5 million, $3.5 million, and $5.3 million of interest income for the notes receivable described above during the years ended December 31, 2023, 2022, and 2021, respectively, none of which was related party interest. Interest income is included in Interest income and other income/(expense), net on the Consolidated Statements of Operations.

Investment in Joint Ventures and Partnerships

We use the equity method to account for investments in joint ventures and partnerships that qualify as VIEs where we are not the primary beneficiary and other entities that we do not control or where we do not own a majority of the economic interest but have the ability to exercise significant influence over the operating and financial policies of the investee. Throughout these financial statements we use the term “joint venture” or “partnership” when referring to investments in entities in which we do not have a 100% ownership interest. The Company also uses the equity method when we function as the managing partner and our venture partner has substantive participating rights or where we can be replaced by our venture partner as managing partner without cause. For a joint venture or partnership accounted for under the equity method, our share of net earnings or losses is reflected as income/loss when earned/incurred and distributions are credited against our investment in the joint venture or partnership as received.

In determining whether a joint venture or partnership is a VIE, the Company considers: the form of our ownership interest and legal structure; the size of our investment; the financing structure of the entity, including necessity of subordinated debt; estimates of future cash flows; ours and our partner’s ability to participate in the decision making related to acquisitions, disposition, budgeting and financing of the entity; obligation to absorb losses and F - 15

preferential returns; nature of our partner’s primary operations; and the degree, if any, of disproportionality between the economic and voting interests of the entity. As of December 31, 2023, the Company held one investment in a joint venture that qualified as a VIE where we were determined to be the primary beneficiary (See Note 5, Joint Ventures and Partnerships, for further discussion).

We evaluate our investments in unconsolidated joint ventures for events or changes in circumstances that indicate there may be an other-than-temporary decline in value. We consider various factors to determine if a decrease in the value of the investment is other-than-temporary. These factors include, but are not limited to, age of the venture, our intent and ability to retain our investment in the entity, the financial condition and long-term prospects of the entity, the fair value of the property of the joint venture, and the relationships with the other joint venture partners and its lenders. The amount of loss recognized is the excess of the investment’s carrying amount over its estimated fair value. If we believe that the decline in fair value is temporary, no impairment is recorded. The aforementioned factors are taken into consideration as a whole by management in determining the valuation of our equity method investments. Should the actual results differ from management’s judgment, the valuation could be negatively affected and may result in a negative impact to our Consolidated Financial Statements.

Derivative Financial Instruments

The Company utilizes derivative financial instruments to manage interest rate risk and generally designates these financial instruments as cash flow hedges. Derivative financial instruments are recorded on our Consolidated Balance Sheets as either an asset or liability and measured quarterly at their fair value. The changes in fair value for cash flow hedges that are deemed effective are reflected in other comprehensive income/(loss) and for non-designated derivative financial instruments in earnings. The ineffective component of cash flow hedges, if any, is recorded in earnings.

Redeemable Noncontrolling Interests in the Operating Partnership and DownREIT Partnership

Interests in the Operating Partnership and the DownREIT Partnership held by limited partners are represented by OP Units and DownREIT Units, respectively. The income is allocated to holders of OP Units/DownREIT Units based upon net income available to common stockholders and the weighted average number of OP Units/DownREIT Units outstanding to total common shares plus OP Units/DownREIT Units outstanding during the period. Capital contributions, distributions, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the partnership agreements of the Operating Partnership and the DownREIT Partnership.

Limited partners of the Operating Partnership and the DownREIT Partnership have the right to require such partnership to redeem all or a portion of the OP Units/DownREIT Units held by the limited partner at a redemption price equal to and in the form of the Cash Amount (as defined in the partnership agreement of the Operating Partnership or the DownREIT Partnership, as applicable), provided that such OP Units/DownREIT Units have been outstanding for at least one year, subject to certain exceptions. UDR, as the general partner of the Operating Partnership and the DownREIT Partnership may, in its sole discretion, purchase the OP Units/DownREIT Units by paying to the limited partner either the Cash Amount or the REIT Share Amount (generally one share of Common Stock of the Company for each OP Unit/DownREIT Unit), as defined in the partnership agreement of the Operating Partnership or the DownREIT Partnership, as applicable. Accordingly, the Company records the OP Units/DownREIT Units outside of permanent equity and reports the OP Units/DownREIT Units at their redemption value using the Company’s stock price at each balance sheet date.

Income Taxes

Due to the structure of the Company as a REIT and the nature of the operations for the operating properties, no provision for federal income taxes has been provided for at UDR. Historically, the Company has generally incurred only state and local excise and franchise taxes. UDR has elected for certain consolidated subsidiaries to be treated as taxable REIT subsidiaries (“TRS”).

Income taxes for our TRS are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured F - 16

DECEMBER 31, 2023

using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rate is recognized in earnings in the period of the enactment date. The Company’s deferred tax assets/(liabilities) are generally the result of differing depreciable lives on capitalized assets, temporary differences between book and tax basis of assets and liabilities and timing of expense recognition for certain accrued liabilities. As of December 31, 2023 and 2022, UDR’s net deferred tax asset/(liability) was ($0.8) million and $(0.8) million, respectively, and are recorded in Accounts payable, accrued expenses and other liabilities on the Consolidated Balance Sheets.

GAAP defines a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. GAAP also provides guidance on derecognition, classification, interest and penalties, accounting for interim periods, disclosure and transition.

The Company recognizes and evaluates its tax positions using a two-step process. First, UDR determines whether a tax position is more likely than not (greater than 50 percent probability) to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Second, the Company will determine the amount of benefit to recognize and record the amount that is more likely than not to be realized upon ultimate settlement.

The Company invests in assets that qualify for federal investment tax credits (“ITC”) through our TRS. An ITC reduces federal income taxes payable when qualifying depreciable property is acquired. The ITC is determined as a percentage of cost of the assets. The Company accounts for ITCs under the deferral method, under which the tax benefit from the ITC is deferred and amortized as a tax benefit into Tax (provision)/benefit, net on the Consolidated Statements of Operations over the book life of the qualifying depreciable property. The ITCs are recorded in Accounts payable, accrued expenses and other liabilities on the Consolidated Balance Sheets.

UDR had no material unrecognized tax benefit, accrued interest or penalties at December 31, 2023. UDR and its subsidiaries are subject to federal income tax as well as income tax of various state and local jurisdictions. The tax years 2020 through 2022 remain open to examination by tax jurisdictions to which we are subject. When applicable, UDR recognizes interest and/or penalties related to uncertain tax positions in Tax (provision)/benefit, net on the Consolidated Statements of Operations.

Principles of Consolidation

The Company accounts for subsidiary partnerships, joint ventures and other similar entities in which it holds an ownership interest in accordance with the consolidation guidance. The Company first evaluates whether each entity is a VIE. Under the VIE model, the Company consolidates an entity when it has control to direct the activities of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the voting model, the Company consolidates an entity when it controls the entity through ownership of a majority voting interest.

Discontinued Operations

In accordance with GAAP, a discontinued operation represents (1) a component of an entity or group of components that has been disposed of or is classified as held for sale in a single transaction and represents a strategic shift that has or will have a major effect on an entity’s financial results, or (2) an acquired business that is classified as held for sale on the date of acquisition. A strategic shift could include a disposal of (1) a separate major line of business, (2) a separate major geographic area of operations, (3) a major equity method investment, or (4) other major parts of an entity.

We record sales of real estate that do not meet the definition of a discontinued operation in Gain/(loss) on sale of real estate owned on the Consolidated Statements of Operations.

Stock-Based Employee Compensation Plans

The Company measures the cost of employee services received in exchange for an award of an equity instrument based on the award’s fair value on the grant date and recognizes the cost as stock-based compensation expense over the period during which the employee is required to provide service in exchange for the award, which is F - 17

generally the vesting period. For performance based awards, the Company remeasures the fair value based on the estimated achievement of the performance criteria each balance sheet date with adjustments made on a cumulative basis until the award is settled and the final compensation is known. Stock-based compensation expense is only recognized for performance based awards that we expect to vest, which we estimate based upon an assessment of the probability that the performance criteria will be achieved. Stock-based compensation expense associated with awards is updated for actual forfeitures. The fair value for market based awards issued by the Company is calculated utilizing a Monte Carlo simulation and the fair value for stock options issued by the Company is calculated utilizing the Black-Scholes-Merton formula. For further discussion, see Note 10, Employee Benefit Plans.

Advertising Costs

All advertising costs are expensed as incurred and reported on the Consolidated Statements of Operations within the line item Property operating and maintenance. During the years ended December 31, 2023, 2022, and 2021, total advertising expense was $9.2 million, $8.7 million, and $8.3 million, respectively.

Cost of Raising Capital

Costs incurred in connection with the issuance of equity securities are deducted from stockholders’ equity. Costs incurred in connection with the issuance or renewal of debt are recorded based on the terms of the debt issuance or renewal. Accordingly, if the terms of the renewed or modified debt instrument are deemed to be substantially different (i.e. a 10 percent or greater difference in the cash flows between instruments), all unamortized financing costs associated with the extinguished debt are charged to earnings in the current period and certain costs of new debt issuances are capitalized and amortized over the term of the debt. When the cash flows are not substantially different, the lender costs associated with the renewal or modification are capitalized and amortized into interest expense over the remaining term of the related debt instrument and other related costs are expensed. The balance of any unamortized financing costs associated with retired debt is expensed upon retirement. Deferred financing costs for new debt instruments include fees and costs incurred by the Company to obtain financing. Deferred financing costs are generally amortized on a straight-line basis, which approximates the effective interest method, over a period not to exceed the term of the related debt.

Comprehensive Income/(Loss)

Comprehensive income/(loss), which is defined as the change in equity during each period from transactions and other events and circumstances from nonowner sources, including all changes in equity during a period except for those resulting from investments by or distributions to stockholders, is displayed in the accompanying Consolidated Statements of Comprehensive Income/(Loss). For the years ended December 31, 2023, 2022, and 2021, the Company’s other comprehensive income/(loss) consisted of the gain/(loss) (effective portion) on derivative instruments that are designated as and qualify as cash flow hedges, (gain)/loss on derivative instruments reclassified from other comprehensive income/(loss) into earnings, and the allocation of other comprehensive income/(loss) to noncontrolling interests. The (gain)/loss on derivative instruments reclassified from other comprehensive income/(loss) is included in Interest expense on the Consolidated Statements of Operations. See Note 14, Derivatives and Hedging Activity, for further discussion. The allocation of other comprehensive income/(loss) to redeemable noncontrolling interests during the years ended December 31, 2023, 2022, and 2021 was $(0.2) million, $0.9 million, and $0.4 million, respectively.

Forward Sales Agreements

From time to time the Company utilizes forward sales agreements for the future issuance of its common stock. When the Company enters into a forward sales agreement, the contract requires the Company to sell its shares to a counterparty at a predetermined price at a future date. The net sales price and proceeds attained by the Company will be determined on the dates of settlement, with adjustments during the term of the contract for the Company’s anticipated dividends as well as for a daily interest factor that varies with changes in the federal funds rate. The Company generally has the ability to determine the dates and method of settlement (i.e., gross physical settlement, net share settlement or cash settlement), subject to certain conditions and the right of the counterparty to accelerate settlement under certain circumstances.

The Company accounts for the shares of common stock reserved for issuance upon settlement as equity in accordance with ASC 815-40, Contracts in Entity's Own Equity, which permits equity classification when a contract is F - 18

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

considered indexed to the entity’s own stock and the contract requires or permits the issuing entity to settle the contract in shares (either physically or net in shares).

The guidance establishes a two-step process for evaluating whether an equity-linked financial instrument is considered indexed to the entity’s own stock, first, evaluating the instrument’s contingent exercise provisions and second, evaluating the instrument’s settlement provisions. When entering into forward sales agreements, we determined that (i) none of the agreement’s exercise contingencies are based on observable markets or indices besides those related to the market for our own stock price; and (ii) none of the settlement provisions preclude the agreements from being indexed to our own stock.

Before the issuance of shares of common stock, upon physical or net share settlement of the forward sales agreements, the Company expects that the shares issuable upon settlement of the forward sales agreements will be reflected in its diluted income/(loss) per share calculations using the treasury stock method. Under this method, the number of shares of common stock used in calculating diluted income/(loss) per share is deemed to be increased by the excess, if any, of the number of shares of common stock that would be issued upon full physical settlement of the forward sales agreements over the number of shares of common stock that could be purchased by the Company in the open market (based on the average market price during the period) using the proceeds receivable upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period). When the Company physically or net share settles any forward sales agreement, the delivery of shares of common stock would result in an increase in the number of weighted average common shares outstanding and dilution to basic income/(loss) per share. (See Note 8, Income/(Loss) per Share for further discussion.)

Lease Receivables

During the years ended December 31, 2023 and 2022, the Company performed an analysis in accordance with the ASC 842, Leases, guidance to assess the collectibility of its operating lease receivables. This analysis included an assessment of collectibility of current and future rents and whether those lease payments were no longer probable of collection. In accordance with the leases guidance, if lease payments are no longer deemed to be probable over the life of the lease contract, we recognize revenue only when cash is received, and all existing contractual operating lease receivables and straight-line lease receivables are reserved.

As of December 31, 2023, the Company’s multifamily tenant lease receivables balance, net of its reserve, was approximately $9.0 million, including its share from unconsolidated joint ventures. The Company’s retail tenant lease receivables balance (exclusive of straight-line rent receivables), net of its reserve, was approximately $0.3 million, including its share from unconsolidated joint ventures, as of December 31, 2023. As of December 31, 2022, the Company’s multifamily tenant lease receivables balance, net of its reserve, was approximately $8.7 million, including its share from unconsolidated joint ventures. The Company’s retail tenant lease receivables balance (exclusive of straight-line rent receivables), net of its reserve, was approximately $4.3 million, including its share from unconsolidated joint ventures, as of December 31, 2022.

Use of Estimates

The preparation of these financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the dates of the financial statements and the amounts of revenues and expenses during the reporting periods. Actual amounts realized or paid could differ from those estimates.

Market Concentration Risk

The Company is subject to increased exposure from economic and other competitive factors specific to markets where the Company holds a significant percentage of the carrying value of its real estate portfolio. At December 31, 2023, the Company held greater than 10% of the carrying value of its real estate portfolio in each of the Metropolitan D.C. and Boston, Massachusetts markets. F - 19

Developments

At December 31, 2023, the Company was developing two wholly-owned communities totaling 415 homes, of which 56 have been completed, in which we have an investment of $160.4 million. The communities are estimated to be completed in the second quarter of 2024.

Other Activity

In connection with the acquisition of certain properties, the Company agreed to pay certain of the tax liabilities of certain contributors if the Company sells one or more of the properties contributed in a taxable transaction prior to the expiration of specified periods of time following the acquisition. The Company may, however, sell, without being required to pay any tax liabilities, any of such properties in a non-taxable transaction, including, but not limited to, a tax deferred Section 1031 exchange.

Further, the Company has agreed to maintain certain debt that may be guaranteed by certain contributors for specified periods of time following the acquisition. The Company, however, has the ability to refinance or repay guaranteed debt or to substitute new debt if the debt and the guaranty continue to satisfy certain conditions.

Amortization of Intangible Assets

The following table provides a summary of the aggregate amortization for the intangible assets acquired in the acquisition of real estate for each of the next five years and thereafter (in thousands):

Unamortized Balance as of December 31, 2023 2024 2025 2026 2027 2028 Thereafter

For the years ended December 31, 2023 and 2022, $4.2 million and $4.3 million, respectively, of amortization expense was recorded in Depreciation and Amortization on the Consolidated Statement of Operations.

(b) In-place lease intangible assets, net is recorded net of accumulated amortization of $9.5 million in Other assets on the Consolidated Balance Sheets. For the years ended December 31, 2023 and 2022, $7.3 million and $22.5 million, respectively, was recorded in Depreciation and Amortization on the Consolidated Statement of Operations.

  1. VARIABLE INTEREST ENTITIES

The Company has determined that the Operating Partnership and DownREIT Partnership are VIEs as the limited partners lack substantive kick-out rights and substantive participating rights. The Company has concluded that it is the primary beneficiary of, and therefore consolidates, the Operating Partnership and DownREIT Partnership based on its role as the sole general partner of the Operating Partnership and DownREIT Partnership. The Company’s role as community manager and its equity interests give us the power to direct the activities that most significantly impact the economic performance and the obligation to absorb potentially significant losses or the right to receive potentially significant benefits of the Operating Partnership and DownREIT Partnership.

  1. JOINT VENTURES AND PARTNERSHIPS

UDR has entered into joint ventures and partnerships with unrelated third parties to own, operate, acquire, renovate, develop, redevelop, dispose of, and manage real estate assets that are either consolidated and included in Real estate owned on the Consolidated Balance Sheets or are accounted for under the equity method of accounting, and are included in Investment in and advances to unconsolidated joint ventures, net, on the Consolidated Balance Sheets. The Company consolidates the entities that we control as well as any variable interest entity where we are the primary beneficiary. Under the VIE model, the Company consolidates an entity when it has control to direct the activities of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the voting model, the Company consolidates an entity when it controls the entity through ownership of a majority voting interest.

UDR’s joint ventures and partnerships are funded with a combination of debt and equity. Our losses are typically limited to our investment and except as noted below, the Company does not guarantee any debt, capital payout or other obligations associated with our joint ventures and partnerships.

Consolidated joint venture

The Company previously held a preferred equity investment in a joint venture that owned a 136 apartment home community located in San Francisco, California. In 2022, the joint venture was deemed to be a VIE and the Company concluded that it was the primary beneficiary of the VIE, and therefore began consolidating the joint venture. In February 2023, the Company took title to the property pursuant to a foreclosure resulting in it being a wholly-owned community.

The Company has a preferred equity investment in a joint venture that owns a 173 apartment home community located in Oakland, California. In December 2023, the developer informed the Company that it would not fund its share of a capital call and subsequently entered into an agreement to transfer its equity interest in the joint venture to the Company for $1.4 million. As a result, the joint venture was deemed to be a VIE. The Company concluded that it is the primary beneficiary of the VIE, and therefore began consolidating the joint venture, resulting in a $24.3 million loss on consolidation which is recorded in Income/(loss) from unconsolidated entities on the Consolidated Statements of Operations. The consolidated assets and liabilities related to the VIE were initially recorded at fair value during December 2023 and were approximately $68.0 million and $42.5 million, respectively, as of December 31, 2023. The Company took title to the developer’s equity interest in the joint venture in January 2024. (See Note 3, Real Estate Owned for more information).

Unconsolidated joint ventures and partnerships

The Company recognizes earnings or losses from our investments in unconsolidated joint ventures and partnerships consisting of our proportionate share of the net earnings or losses of the joint ventures and partnerships. In addition, we may earn fees for providing management services for the communities held by the unconsolidated joint ventures and partnerships. F - 24

(b) In June 2023, the Company formed a new real estate joint venture, UDR/LaSalle, with LaSalle Investment Management on behalf of an institutional client (“LaSalle”). Four operating communities, located in various markets, were contributed by the Company. The joint venture partner paid the Company approximately $247.9 million at formation of the joint venture. The Company will have the potential to earn a promoted return should certain return hurdles be achieved. Our initial investment was $258.2 million and consisted solely of our equity in the four operating communities contributed to the joint venture.

At December 31, 2023, our preferred equity investment portfolio consisted of 23 communities located in various markets, consisting of 5,618 completed or under development homes. In addition, the Company’s preferred equity investments include four investments that receive a variable percentage of the value created from the project upon a capital or liquidating event. During the year ended December 31, 2023, the Company did not enter into or fund any new preferred equity investments and no preferred equity investments were redeemed.

(g) In June 2023, the agreement for one preferred equity investment was amended, resulting in the Company’s investment, inclusive of accrued preferred return, being classified as a note receivable on the Consolidated Balance Sheet as of December 31, 2023. (See Note 2, Significant Accounting Policies for further discussion.)

As disclosed above, the Company began consolidating one preferred investment in December 2023, resulting in a $24.3 million loss on consolidation classified in Income/(loss) from unconsolidated entities.

As of December 31, 2023 and 2022, the Company had deferred fees of $7.6 million and $8.1 million, respectively, which will be recognized through earnings over the weighted average life of the related properties, upon the disposition of the properties to a third party, or upon completion of certain development obligations.

The Company recognized management fees of $6.8 million, $5.0 million, and $6.1 million during the years ended December 31, 2023, 2022, and 2021, respectively, for management of the communities held by the joint ventures and partnerships. The management fees are included in Joint venture management and other fees on the Consolidated Statements of Operations.

The Company may, in the future, make additional capital contributions to certain of our joint ventures and partnerships should additional capital contributions be necessary to fund acquisitions or operations.

We consider various factors to determine if a decrease in the value of our Investment in and advances to unconsolidated joint ventures, net is other-than-temporary. These factors include, but are not limited to, age of the venture, our intent and ability to retain our investment in the entity, the financial condition and long-term prospects of the entity, and the relationships with the other joint venture partners and its lenders. Based on the significance of the unobservable inputs, we classify these fair value measurements within Level 3 of the valuation hierarchy. The Company did not incur any other-than-temporary impairments in the value of its investments in unconsolidated joint ventures during the years ended December 31, 2023, 2022, and 2021. F - 26

  1. LEASES

Lessee - Ground Leases

UDR has six communities that are subject to ground leases, under which UDR is the lessee, that expire between 2043 and 2103, inclusive of extension options we are reasonably certain will be exercised. All of these leases are classified as operating leases through the lease term expiration based on our election of the practical expedient provided by the leasing standard. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the remaining lease term. We currently do not hold any finance leases. The Company also elected the short-term lease exception provided by the leasing standard and therefore only recognizes right-of-use assets and lease liabilities for leases with a term greater than one year. No leases qualified for the short-term lease exception during the years ended December 31, 2023 and 2022.

As of December 31, 2023 and 2022, the Operating lease right-of-use assets were $190.6 million and $194.1 million, respectively, and the Operating lease liabilities were $185.8 million and $189.2 million, respectively, on our Consolidated Balance Sheets related to our ground leases. The value of the Operating lease right-of-use assets exceeds the value of the Operating lease liabilities due to prepaid lease payments. The calculation of these amounts includes minimum lease payments over the remaining lease term (described further in the table below). Variable lease payments are excluded from the right-of-use assets and lease liabilities and are recognized in earnings in the period in which the obligation for those payments is incurred.

As the discount rate implicit in the leases was not readily determinable, we determined the discount rate for these leases utilizing the Company’s incremental borrowing rate at a portfolio level, adjusted for the remaining lease term, and the form of underlying collateral.

The weighted average remaining lease term for these leases was 42.0 years and 42.6 years at December 31, 2023 and 2022, respectively, and the weighted average discount rate was 5.0% at both December 31, 2023 and 2022.

Future minimum lease payments and total operating lease liabilities from our ground leases as of December 31, 2023 are as follows (dollars in thousands):

Difference between future undiscounted cash flows and discounted cash flows (281,826)
Total operating lease liabilities (discounted) $ 185,836

For purposes of recognizing our ground lease contracts, the Company uses the minimum lease payments, if stated in the agreement. For ground lease agreements where there is a rent reset provision based on a change in an index or a rate (i.e., changes in fair market rental rates or changes in the consumer price index) but that does not include a specified minimum lease payment, the Company uses the current rent over the remainder of the lease term. If there is a contingency upon which some or all of the variable lease payments that will be paid over the remainder of the lease term are based, which is resolved such that those payments now meet the definition of lease payments, the Company will remeasure the right-of-use asset and lease liability on the reset date.

The components of operating lease expenses were as follows (dollars in thousands):

Lessor - Apartment Home, Retail and Commercial Space Leases

UDR’s communities and retail and commercial space are leased to tenants under operating leases. As of December 31, 2023, our apartment home leases generally have initial terms of 12 months or less. As of December 31, 2023, our retail and commercial space leases generally have initial terms of between 5 and 15 years and represent approximately 1% to 2% of our total lease revenue. Our apartment home leases are generally renewable at the end of the lease term, subject to potential changes in rental rates, and our retail and commercial space leases generally have renewal options, subject to associated increases in rental rates due to market-based or fixed-price renewal options and certain other conditions. (See Note 16, Reportable Segments for further discussion around our major revenue streams and disaggregation of our revenue.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

For purposes of classification of the above table, variable rate debt with a derivative financial instrument designated as a cash flow hedge is deemed as fixed rate debt due to the Company having effectively established a fixed interest rate for the underlying debt instrument.

Our secured debt instruments generally feature either monthly interest and principal or monthly interest-only payments with balloon payments due at maturity. As of December 31, 2023, secured debt encumbered approximately 14% of UDR’s total real estate owned based upon gross book value (approximately 86% of UDR’s real estate owned based on gross book value is unencumbered).

(a) At December 31, 2023, fixed rate mortgage notes payable are generally due in monthly installments of principal and interest and mature at various dates from July 2024 through February 2031 and carry interest rates ranging from 2.62% to 4.39%.

The Company will from time to time acquire properties subject to fixed rate debt instruments. In those situations, the Company records the debt at its estimated fair value and amortizes any difference between the fair value and par value to interest expense over the term of the underlying debt instrument.

In August 2023, the Company assumed secured fixed rate mortgage notes payable with an outstanding balance of $209.4 million and a fair value of $191.7 million in connection with the acquisition of six operating communities. The six mortgages had outstanding balances ranging from $28.0 million to $40.0 million and carry interest rates from 3.24% to 4.12% (see Note 3, Real Estate Owned).

(b) During the years ended December 31, 2023, 2022, and 2021, the Company had $3.4 million, $4.5 million, and $3.9 million, respectively, of amortization of the fair market adjustment of debt assumed in the acquisition of properties inclusive of its fixed rate mortgage notes payable, which was included in Interest expense on the Consolidated Statements of Operations. The unamortized fair market adjustment was a net premium of $1.5 million and $22.5 million at December 31, 2023 and 2022, respectively. The change in net premium was primarily due to the assumption of fixed rate mortgages discussed in footnote (a) above.

(c) In December 2023, the Company began consolidating a preferred equity investment which included a secured variable rate senior construction loan with an outstanding balance of $40.0 million. The senior construction loan had an interest rate of 8.33% as of December 31, 2023 (see Note 5, Joint Ventures and Partnerships).

(d) The variable rate mortgage note payable secures a tax-exempt housing bond issue that matures in March 2032. Interest on this note is payable in monthly installments. As of December 31, 2023, the variable interest rate on the mortgage note was 4.08%.

(e) The Company has a $1.3 billion unsecured revolving credit facility (the “Revolving Credit Facility”) and a $350.0 million unsecured term loan (the “Term Loan”). The credit agreement for these facilities ( the “Credit Agreement”) allows the total commitments under the Revolving Credit Facility and the total borrowings under the Term Loan to be increased to an aggregate maximum amount of up to $2.5 billion, subject to certain conditions, including obtaining commitments from one or more lenders. The Revolving Credit Facility has a scheduled maturity date of January 31, 2026, with two six-month extension options, subject to certain conditions. The Term Loan has a scheduled maturity date of January 31, 2027.

Based on the Company’s current credit rating, the Revolving Credit Facility has an interest rate equal to Adjusted SOFR plus a margin of 75.5 basis points and a facility fee of 15 basis points, and the Term Loan has an interest rate equal to Adjusted SOFR plus a margin of 83.0 basis points. Depending on the Company’s credit rating, the margin under the Revolving Credit Facility ranges from 70 to 140 basis points, the facility fee ranges from 10 to 30 basis points, and the margin under the Term Loan ranges from 75 to 160 basis points. Further, the Credit Agreement includes sustainability adjustments pursuant to which the applicable margin for the Revolving Credit Facility and the Term Loan were reduced by **** two **** basis points upon the Company receiving certain green building certifications, which is reflected in the margins noted above.

In August 2021 and March 2023, the Company entered into five interest rate swaps totaling a $350.0 million of notional value, which became effective in July 2022 and in March 2023, to hedge against interest rate risk on all or a F - 32

  1. INCOME/(LOSS) PER SHARE

The following table sets forth the computation of basic and diluted income/(loss) per share for the periods presented (dollars and shares in thousands, except per share data):

Year Ended December 31,
**** 2023 2022 2021
Numerator for income/(loss) per share:
Net income/(loss) $ 474,488 $ 92,579 $ 160,993
Net (income)/loss attributable to redeemable noncontrolling interests in the Operating Partnership and DownREIT Partnership **** (30,104) (5,613) (10,873)
Net (income)/loss attributable to noncontrolling interests **** (31) (42) (104)
Net income/(loss) attributable to UDR, Inc. **** 444,353 86,924 150,016
Distributions to preferred stockholders — Series E (Convertible) **** (4,848) (4,412) (4,229)
Income/(loss) attributable to common stockholders - basic and diluted $ 439,505 $ 82,512 $ 145,787
Denominator for income/(loss) per share:
Weighted average common shares outstanding **** 329,136 321,949 300,579
Non-vested restricted stock awards **** (371) (278) (253)
Denominator for basic income/(loss) per share **** 328,765 321,671 300,326
Incremental shares issuable from assumed conversion of unvested LTIP Units, performance units, unvested restricted stock and shares issuable upon settlement of forward sales agreements **** 339 1,029 1,377
Denominator for diluted income/(loss) per share **** 329,104 322,700 301,703
Income/(loss) per weighted average common share:
Basic $ 1.34 $ 0.26 $ 0.49
Diluted $ 1.34 $ 0.26 $ 0.48

Basic income/(loss) per common share is computed based upon the weighted average number of common shares outstanding. Diluted income/(loss) per common share is computed based upon the weighted average number of common shares outstanding plus the common shares issuable from the assumed conversion of the OP Units and DownREIT Units, convertible preferred stock, stock options, unvested long-term incentive plan units (“LTIP Units”), performance units, unvested restricted stock and continuous equity program forward sales agreements. Only those instruments having a dilutive impact on our basic income/(loss) per share are included in diluted income/(loss) per share during the periods. For the years ended December 31, 2023, 2022, and 2021, the effect of the conversion of the OP Units, DownREIT Units and the Company’s Series E preferred stock was not dilutive and therefore not included in the above calculation.

In July 2021, the Company entered into an ATM sales agreement under which the Company may offer and sell up to 20.0 million shares of its common stock, from time to time, to or through its sales agents and may enter into separate forward sales agreements to or through its forward purchasers. Upon entering into the ATM sales agreement, the Company simultaneously terminated the sales agreement for its prior at-the-market equity offering program, which was entered into in July 2017. During the year ended December 31, 2023, the Company did not sell any shares of common stock through its ATM program. As of December 31, 2023, we had 14.0 million shares of common stock available for future issuance under the ATM program.

In connection with any forward sales agreement under the Company’s ATM program, the relevant forward purchasers will borrow from third parties and, through the relevant sales agent, acting in its role as forward seller, sell a number of shares of the Company’s common stock equal to the number of shares underlying the agreement. The Company does not initially receive any proceeds from any sale of borrowed shares by the forward seller.

The Company generally has the ability to determine the dates and method of settlement (i.e., gross physical settlement, net share settlement or cash settlement), subject to certain conditions and the right of the counterparty to accelerate settlement under certain circumstances. The Company currently expects to fully physically settle each forward sales agreement with the relevant forward purchaser on one or more dates specified by the Company on or prior to the maturity date of that particular forward sales agreement, in which case the Company expects to receive aggregate net F - 36

cash proceeds at settlement equal to the number of shares underlying the particular forward sales agreement multiplied by the relevant forward sale price. However, subject to certain exceptions, the Company may also elect, in its discretion, to cash settle or net share settle a particular forward sales agreement, in which case the Company may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and the Company may owe cash (in the case of cash settlement) or shares of UDR common stock (in the case of net share settlement) to the relevant forward purchaser.

During the year ended December 31, 2023, the Company did not enter into any forward purchase agreements under its continuous equity program.

In June 2022, the Company settled all 4.4 million shares under the outstanding forward sales agreements under its ATM program at a weighted average forward price per share of $52.46, which is inclusive of adjustments made to reflect the then-current federal funds rate, the amount of dividends paid to holders of UDR common stock over the term of the agreements and commissions paid to sales agents of approximately $7.5 million, for net proceeds of $230.9 million.

In March 2022, in connection with an underwritten public offering, the Company entered into forward sales agreements to sell 7.0 million shares of its common stock at an initial forward price per share of $57.565. The actual forward price per share received by the Company upon settlement was determined on the applicable settlement dates based on adjustments made to the initial forward price to reflect the then-current federal funds rate and the amount of dividends paid to holders of UDR common stock over the term of the forward sales agreements. During the year ended December 31, 2022, the Company settled all 7.0 million shares under the forward sales agreements at a weighted average forward price per share of $57.07, which is inclusive of adjustments made to reflect the then-current federal funds rate and the amount of dividends paid to holders of UDR common stock, for net proceeds of $399.5 million.

As described above, during the year ended December 31, 2022, the Company settled all 11.4 million shares in aggregate under previously announced forward sales agreements, including under the ATM program, for net proceeds of $630.4 million. Aggregate net proceeds from such forward sales, after deducting related expenses, were $629.6 million.

During the year ended December 31, 2023, the Company repurchased 0.6 million shares of its common stock at an average price of $40.13 per share for total consideration of approximately $25.0 million under its share repurchase program. During the year ended December 31, 2022, the Company repurchased 1.2 million shares of its common stock at an average price of $41.14 per share for total consideration of approximately $49.0 million under its share repurchase program.

The following table sets forth the additional shares of common stock outstanding by equity instrument if converted to common stock for each of the years ended December 31, 2023, 2022, and 2021 (in thousands):

Distributions are subject to the approval of the Board of Directors and are dependent upon our strategy, financial condition and operating results. UDR’s common distributions for the years ended December 31, 2023, 2022, and 2021 totaled $1.68, $1.52, and $1.45 per share, respectively.

Preferred Stock

The Series E Cumulative Convertible Preferred Stock (“Series E”) has no stated par value and a liquidation preference of $16.61 per share. Subject to certain adjustments and conditions, each share of the Series E is convertible at any time at the holder’s option into one share of our common stock prior to a “Special Dividend” declared in 2008 (1.083 shares after the Special Dividend). The holders of the Series E are entitled to vote on an as-converted basis as a single class in combination with the holders of common stock at any meeting of our stockholders for the election of directors or for any other purpose on which the holders of common stock are entitled to vote. The Series E has no stated maturity and is not subject to any sinking fund or any mandatory redemption.

Distributions declared on the Series E for the years ended December 31, 2023, 2022, and 2021 were $1.82, $1.65, and $1.57 per share, respectively. The Series E is not listed on any exchange. At December 31, 2023 and 2022, a total of 2.7 million and 2.7 million, respectively, shares of the Series E were outstanding.

UDR is authorized to issue up to 20.0 million shares of the Series F Preferred Stock (“Series F”). The Series F may be purchased by certain holders of OP Units and DownREIT Units, at a purchase price of $0.0001 per share. OP/DownREIT Unitholders are entitled to subscribe for and purchase one share of UDR’s Series F for each OP/DownREIT Unit held. During the years ended December 31, 2023 and 2022, 0.2 million and 0.5 million of the Series F shares were forfeited upon the conversion of OP Units and DownREIT Units into Company common stock, respectively.

At December 31, 2023 and 2022, a total of 11.9 million and 12.1 million shares, respectively, of the Series F were outstanding with an aggregate purchase value of $1,187 and $1,210, respectively. Holders of the Series F are entitled to one vote for each share of the Series F they hold, voting together with the holders of our common stock, on each matter submitted to a vote of security holders at a meeting of our stockholders. The Series F does not entitle its holders to dividends or any other rights, privileges or preferences.

Distribution Reinvestment and Stock Purchase Plan

UDR’s Distribution Reinvestment and Stock Purchase Plan allows common and preferred stockholders the opportunity to purchase, through the reinvestment of cash dividends and by making additional cash payments, additional shares of UDR’s common stock. During the year ended December 31, 2023, all shares issued with respect to the plan were acquired through the open market.

  1. EMPLOYEE BENEFIT PLANS

In May 2022, the stockholders of UDR approved an amendment and restatement to the LTIP. The LTIP authorizes the granting of awards which may take the form of options to purchase shares of common stock, stock appreciation rights, restricted stock, dividend equivalents, partnership interests in the Operating Partnership designated as LTIP Units, performance partnership interests in the Operating Partnership designated as Performance Units, other stock-based awards, and any other right or interest relating to common stock or cash incentive awards to Company directors, employees and outside trustees to promote the success of the Company by linking individual’s compensation via grants of share based payment.

LTIP Units and Performance Units are designed to qualify as “profits interests” in the Operating Partnership for federal income tax purposes, meaning that initially they are not economically equivalent in value to a share of our common stock, but over time can increase in value to one-for-one parity with common stock by operation of special tax rules applicable to profits interests. Until and unless such parity is reached, the value that an executive will realize for a given number of vested LTIP Units or Performance Units is less than the value of an equal number of shares of our common stock.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

As of December 31, 2023, 35.0 million shares were reserved on an unadjusted basis for issuance upon the grant or exercise of awards under the LTIP. As of December 31, 2023, there were 10.6 million common shares available for issuance under the LTIP.

The LTIP contains double trigger change of control provisions allowing for the vesting of an award when certain conditions are met upon qualifying events such as a merger where UDR is not the surviving entity. Upon the death or disability of an award recipient, all outstanding instruments will vest and all restrictions will lapse. The LTIP specifies that in the event of a capital transaction, which includes but is not limited to stock dividends, stock splits, extraordinary cash dividends and spin-offs, the number of shares available for grant in totality or to a single individual is to be adjusted proportionately. The LTIP specifies that when a capital transaction occurs that would dilute the holder of the stock award, prior grants are to be adjusted such that the recipient is no worse as a result of the capital transaction.

A summary of UDR’s Performance Units, LTIP Units, restricted stock and option activities during the year ended December 31, 2023 is as follows (shares in thousands):

Restricted Stock Awards

Restricted stock awards are granted to our employees and Company directors. The restricted stock awards are valued based upon the closing sales price of UDR common stock on the date of grant. Compensation expense is recorded under either the straight-line method or graded vesting method over the vesting period, which is generally one to four years. Restricted stock awards earn dividends payable in cash or dividend reinvestment shares. Some of the restricted stock grants are based on the Company’s performance and are subject to adjustment during the initial one to three year performance periods. During the years ended December 31, 2023, 2022, and 2021, we recognized $6.4 million, $5.7 million, and $4.5 million of compensation expense, net of capitalization, related to the amortization of restricted stock awards, respectively. The total remaining compensation cost on unvested restricted stock awards was $5.4 million and had a weighted average remaining contractual life of 2.0 years as of December 31, 2023.

Unit Awards

Unit awards are granted to our employees and Company directors. Compensation expense is recorded under either the straight-line method or graded vesting method over the vesting period, which is generally one to four years. Unit awards earn distributions payable in cash or distribution reinvestment units. Some of the Unit awards are based on the Company’s performance and are subject to adjustment during the initial one to three year performance periods. During the years ended December 31, 2023, 2022, and 2021, we recognized $6.2 million, $15.9 million and $5.9 million, respectively, of compensation expense, net of capitalization, related to the amortization of the awards. The total remaining compensation cost on Unit awards was $3.7 million and had a weighted average remaining contractual life of 1.3 years as of December 31, 2023.

Performance Unit Awards

UDR has granted Performance Units to our employees and Company directors. Subject to certain conditions, each Performance Unit is exercisable into one Operating Partnership common unit. Compensation expense is recorded under either the straight-line method or graded vesting method over the vesting period, which is generally one to four years. Performance Unit awards earn distributions payable in cash equivalent to 2% of regular distributions paid on OP Units. Some of the Performance Unit awards are based on the Company’s performance and are subject to adjustment during the initial one to three year performance periods.

The total remaining compensation cost on unvested Performance Units was $11.6 million as of December 31, 2023.

During the year ended December 31, 2023, no Performance Units were exercised.

The weighted average remaining contractual life on all Performance Units outstanding as of December 31, 2023 is 8.1 years and such Performance Units have a weighted average exercise price of $41.25.

During the years ended December 31, 2023, 2022 and 2021, we recognized $19.8 million, $5.2 million and $11.7 million, respectively, of net compensation expense related to outstanding Performance Units.

Short-Term Incentive Compensation

In January 2023, certain officers of the Company were awarded either a restricted stock grant, an STI Unit grant, or an STI Performance Unit grant, or a combination of all three, under the 2023 Long-Term Incentive Program (“2023 LTI”). All three of the awards represent short-term incentive compensation for the officers. The restricted stock award was valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant in accordance with ASC 718, Compensation - Stock Compensation (“ASC 718”), or $38.59 per share. The STI Unit award was valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant in accordance with ASC 718, or $38.59 per unit, inclusive of a discount due to uncertainty associated with the STI Unit reaching parity with the value of a share of UDR common stock. The STI Performance Unit award was valued for compensation expense purposes on the date of grant in accordance with ASC 718 as determined by the lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 29.0%, an expected life of 5.5 years, an annualized risk-free rate of 4.09%, and an annual dividend yield of 3.3%, or $7.86 per unit, inclusive of a discount due to uncertainty associated with the STI Performance Unit reaching parity with the value of a F - 41

share of UDR common stock. The restricted stock awards, STI Unit awards, and STI Performance Unit awards are primarily based on the Company’s performance and are subject to adjustment based on performance against predefined metrics during the one-year performance period.

In January 2022, certain officers of the Company were awarded STI Unit grants under the 2022 Long-Term Incentive Program (“2022 LTI”). The STI Unit awards represent short-term incentive compensation for the officers and were valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant in accordance with ASC 718, Compensation - Stock Compensation, or $51.10 per unit, inclusive of a discount due to uncertainty associated with the STI Unit reaching parity with the value of a share of UDR common stock. The STI Unit awards are primarily based on the Company’s performance and are subject to adjustment based on performance against predefined metrics during the one-year performance period.

In January 2021, certain officers of the Company were awarded STI Performance Unit grants under the 2021 Long-Term Incentive Program (“2021 LTI”). The STI Performance Unit awards represent short-term incentive compensation for the officers and were valued for compensation expense purposes on the date of grant in accordance with ASC 718, Compensation - Stock Compensation, as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 27.0%, an expected life of 5.5 years, an annualized risk-free rate of 0.49%, and an annual dividend yield of 3.4%, or $5.06 per unit, inclusive of a discount due to uncertainty associated with the STI Performance Unit reaching parity with the value of a share of UDR common stock. The STI Performance Unit awards are primarily based on the Company’s performance and are subject to adjustment based on performance against predefined metrics during the one-year performance period.

Long-Term Incentive Compensation

In January 2023, certain officers of the Company were awarded either a restricted stock grant, an LTIP Unit grant, or an LTIP Performance Unit grant, or a combination of all three, under the 2023 LTI. For all three restricted stock grants, LTIP Unit grants and Performance Unit grants, thirty percent of the 2023 LTI award is based upon FFO as Adjusted over a one-year period and will vest fifty percent on the one-year anniversary and fifty percent on the two-year anniversary. Fifteen percent of the 2023 LTI award is based upon relative FFO as Adjusted over a three-year period and will vest 100% at the end of the three-year performance period. The remaining fifty-five percent of the 2023 LTI award is based on Total Shareholder Return (“TSR”) as measured relative to comparable apartment REITs over a three-year period and as measured relative to the Nareit Equity REITs Total Return Index over a three-year period whereby all three will vest 100% at the end of the three-year performance periods. The portion of the restricted stock grant based upon FFO as Adjusted was valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant or $38.59 per share. Because LTIP Units are granted at the maximum potential payout and there is uncertainty associated with an LTIP Unit reaching parity with the value of a share of UDR common stock, the portion of the LTIP Unit grant based upon the one-year FFO as Adjusted was valued for compensation expense purposes at $17.58 per unit on the grant date, inclusive of an 8.9% discount, and the portion of the LTIP Unit grant based upon the three-year FFO as Adjusted was valued for compensation expense purposes at $18.45 per unit on the grant date, inclusive of a 4.4% discount. Because LTIP Performance Units are granted at the maximum potential payout and there is uncertainty associated with an LTIP Performance Unit reaching parity with the value of a share of UDR common stock, the portion of the LTIP Performance Unit grant based upon the one-year FFO as Adjusted was valued for compensation expense purposes at $4.12 per unit on the grant date, inclusive of an 8.9% discount, a volatility factor of 29.0%, an expected life of 5.5 years, an annualized risk-free rate of 4.09%, and an annual dividend yield of 3.3%, and the portion of the LTIP Unit grant based upon the three-year FFO as Adjusted was valued for compensation expense purposes at $4.29 per unit on the grant date, inclusive of a 4.4% discount, a volatility factor of 27.0%, an expected life of 6.5 years, an annualized risk-free rate of 4.08%, and an annual dividend yield of 3.3%. The portion of the restricted stock grant based upon relative TSR was valued for compensation expense purposes at $44.85 per share for the comparable apartment REITs component and $43.30 per share for the Nareit Equity REITs Total Return Index component on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 36.0%. The portion of the LTIP Unit grant based upon relative TSR was valued for compensation expense purposes at $21.62 per unit, inclusive of a 4.4% discount, for the comparable apartment REITs component and $20.89 per unit, inclusive of a 4.4% discount, for the Nareit Equity REITs Total Return Index component on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 36.0%. The portion of the LTIP Performance Unit grant based upon relative TSR was valued for compensation expense purposes at $6.02 per unit, inclusive of a 4.4% discount, for the comparable F - 42

In January 2022, certain officers of the Company were awarded either a restricted stock grant or an LTIP Unit grant, or a combination of both, under the 2022 LTI. For both restricted stock grants and LTIP Unit grants, thirty percent of the 2022 LTI award is based upon FFO as Adjusted over an approximately one-year period and will vest fifty percent on the one-year anniversary and fifty percent on the two-year anniversary. Fifteen percent of the 2022 LTI award is based upon relative FFO as Adjusted over a three-year period and will vest 100% at the end of the three-year performance period. The remaining fifty-five percent of the 2022 LTI award is based on Total Shareholder Return (“TSR”) as measured relative to comparable apartment REITs over a three-year period and as measured relative to the Nareit Equity REITs Total Return Index over a three-year period whereby both will vest 100% at the end of the three-year performance periods. The portion of the restricted stock grant based upon FFO as Adjusted was valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant or $59.90 per share. Because LTIP Units are granted at the maximum potential payout and there is uncertainty associated with an LTIP Unit reaching parity with the value of a share of UDR common stock, the portion of the LTIP Unit grant based upon the one-year FFO as Adjusted was valued for compensation expense purposes at $27.04 per unit on the grant date, inclusive of a 9.7% discount, and the portion of the LTIP Unit grant based upon the three-year FFO as Adjusted was valued for compensation expense purposes at $28.72 per unit on the grant date, inclusive of a 4.1% discount. The portion of the restricted stock grant based upon relative TSR was valued for compensation expense purposes at $66.83 per share for the comparable apartment REITs component and $68.02 per share for the Nareit Equity REITs Total Return Index component on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 33.0%. The portion of the LTIP Unit grant based upon relative TSR was valued for compensation expense purposes at $31.95 per unit, inclusive of a 4.1% discount, for the comparable apartment REITs component and $32.85 per unit, inclusive of a 4.1% discount, for the Nareit Equity REITs Total Return Index component on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 33.0%.

In January 2021, certain officers of the Company were awarded either a restricted stock grant, an LTIP Unit grant, or an LTIP Performance Unit grant, or a combination of all three, under the 2021 LTI. For all three restricted stock grants, LTIP Unit grants and Performance Unit grants, thirty percent of the 2021 LTI award is based upon FFO as Adjusted over an approximately one-year period and will vest fifty percent on the one-year anniversary and fifty percent on the two-year anniversary. Fifteen percent of the 2021 LTI award is based upon relative FFO as Adjusted over a three-year period and will vest 100% at the end of the three-year performance period. The remaining fifty-five percent of the 2021 LTI award is based on Total Shareholder Return (“TSR”) as measured relative to comparable apartment REITs over a three-year period and as measured relative to the Nareit Equity REITs Total Return Index over a three-year period whereby all three will vest 100% at the end of the three-year performance periods. The portion of the restricted stock grant based upon FFO as Adjusted was valued for compensation expense purposes based upon the closing sales price of UDR common stock on the date of grant or $36.85 per share. Because LTIP Units are granted at the maximum potential payout and there is uncertainty associated with an LTIP Unit reaching parity with the value of a share of UDR common stock, the portion of the LTIP Unit grant based upon the one-year FFO as Adjusted was valued for compensation expense purposes at $16.69 per unit on the grant date, inclusive of a 9.4% discount, and the portion of the LTIP Unit grant based upon the three-year FFO as Adjusted was valued for compensation expense purposes at $17.71 per unit on the grant date, inclusive of a 3.9% discount. Because LTIP Performance Units are granted at the maximum potential payout and there is uncertainty associated with an LTIP Performance Unit reaching parity with the value of a share of UDR common stock, the portion of the LTIP Performance Unit grant based upon the one-year FFO as Adjusted was valued for compensation expense purposes at $2.67 per unit on the grant date, inclusive of a 9.4% discount, a volatility factor of 27.0%, an expected life of 5.5 years, an annualized risk-free rate of 0.49%, and an annual dividend yield of 3.4%, and the portion of the LTIP Unit grant based upon the three-year FFO as Adjusted was valued for compensation expense purposes at $2.85 per unit on the grant date, inclusive of a 3.9% discount, a volatility factor of 26.0%, an expected life of 6.5 years, an annualized risk-free rate of 0.57%, and an annual dividend yield of 3.4%. The portion of the restricted stock grant based upon relative TSR was valued for compensation expense purposes at $40.09 per share for the comparable apartment REITs component and $39.95 per share for the Nareit Equity REITs Total Return Index component on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo F - 43

Profit Sharing Plan

Our profit sharing plan (the “Plan”) is a defined contribution plan covering all eligible full-time employees. Under the Plan, UDR makes discretionary profit sharing and matching contributions to the Plan as determined by the Compensation Committee of the Board of Directors. Aggregate provisions for contributions, both matching and discretionary, which are included in General and administrative on UDR’s Consolidated Statements of Operations for the years ended December 31, 2023, 2022, and 2021, were $1.1 million, $1.7 million, and $1.4 million, respectively.

  1. INCOME TAXES

For 2023, 2022, and 2021, UDR believes that we have complied with the REIT requirements specified in the Code. As such, the REIT would generally not be subject to federal income taxes.

For income tax purposes, distributions paid to common stockholders may consist of ordinary income, qualified dividends, capital gains, unrecaptured section 1250 gains, return of capital, or a combination thereof. Distributions that exceed our current and accumulated earnings and profits constitute a return of capital rather than taxable income and reduce the stockholder’s basis in their common shares. To the extent that a distribution exceeds both current and accumulated earnings and profits and the stockholder’s basis in the common shares, it generally will be treated as a gain from the sale or exchange of that stockholder’s common shares. Taxable distributions paid per common share were taxable as follows for the years ended December 31, 2023, 2022 and 2021 (unaudited):

Year Ended December 31,
2023 2022 2021

The Company’s Tax benefit/(provision), net was $(2.1) million, $(0.3) million and $(1.4) million for the years ended December 31, 2023, 2022 and 2021, respectively. The increase of $1.8 million was primarily attributable to an increase in state taxes, as well as an increase in TRS income of $1.0 million. GAAP defines a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The financial statements reflect expected future tax consequences of income tax positions presuming the taxing authorities’ full knowledge of the tax position and all relevant facts, but without considering time values. GAAP also provides guidance on derecognition, classification, interest and penalties, accounting for interim periods, disclosure and transition.

The Company evaluates our tax position using a two-step process. First, we determine whether a tax position is more likely than not (greater than 50 percent probability) to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Company will then determine the amount of benefit to recognize and record the amount of the benefit that is more likely than not to be realized upon ultimate settlement. As of December 31, 2023 and 2022, UDR has no material unrecognized income tax benefits/(provisions), net.

The Company files income tax returns in federal and various state and local jurisdictions. The tax years 2020 through 2022 remain open to examination by the major taxing jurisdictions to which the Company is subject.

  1. NONCONTROLLING INTERESTS

Redeemable Noncontrolling Interests in the Operating Partnership and DownREIT Partnership

Interests in the Operating Partnership and the DownREIT Partnership held by limited partners are represented by OP Units and DownREIT Units, respectively. The income is allocated to holders of OP Units/DownREIT Units based upon net income attributable to common stockholders and the weighted average number of OP Units/DownREIT Units outstanding to total common shares plus OP Units/DownREIT Units outstanding during the period. Capital contributions, distributions, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the partnership agreements of the Operating Partnership and the DownREIT Partnership.

Limited partners of the Operating Partnership and the DownREIT Partnership have the right to require such partnership to redeem all or a portion of the OP Units/DownREIT Units held by the limited partner at a redemption price equal to and in the form of the Cash Amount (as defined in the partnership agreement of the Operating Partnership or the DownREIT Partnership, as applicable), provided that such OP Units/DownREIT Units have been outstanding for at least one year, subject to certain exceptions. UDR, as the general partner of the Operating Partnership and the DownREIT Partnership may, in its sole discretion, purchase the OP Units/DownREIT Units by paying to the limited partner either the Cash Amount or the REIT Share Amount (generally one share of common stock of the Company for each OP Unit/DownREIT Unit), as defined in the partnership agreement of the Operating Partnership or the DownREIT Partnership, as applicable. Accordingly, the Company records the OP Units/DownREIT Units outside of permanent equity and reports the OP Units/DownREIT Units at their redemption value using the Company’s stock price at each balance sheet date.

Noncontrolling Interests

Noncontrolling interests represent interests of unrelated partners in certain consolidated affiliates, and are presented as part of equity on the Consolidated Balance Sheets since these interests are not redeemable. Net (income)/loss attributable to noncontrolling interests was less than $(0.1) million, less than $(0.1) million, and $(0.1) million during the years ended December 31, 2023, 2022, and 2021, respectively.

  1. FAIR VALUE OF DERIVATIVES AND FINANCIAL INSTRUMENTS

Fair value is based on the price that would be received to sell an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level valuation hierarchy prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below:

Level 1 — Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2 — Observable inputs other than prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated with observable market data.
--- ---
Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

(c) The Company holds a direct investment in a publicly traded real estate technology company, SmartRent. The investment is valued at the market price on December 31, 2023 and 2022. The Company currently classifies the investment as Level 1 in the fair value hierarchy. During the years ended December 31, 2023 and 2022, the Company increased its direct investment in SmartRent due to stock distributions from its unconsolidated real estate technology investments. During the year ended December 31, 2023, the Company sold 4.6 million shares of SmartRent at an average price per share of $3.18 for net proceeds of $14.4 million and recognized a net realized/unrealized gain on sale of $2.5 million recorded in Interest income and other income/(expense), net on the Consolidated Statement of Operations. During the year ended December 31, 2022, the Company did not sell any shares of SmartRent.

Financial Instruments Carried at Fair Value

The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived F - 49

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

from observable market interest rate curves. The fair values of interest rate swaps and caps are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities.

The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2023 and 2022, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. In conjunction with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Redeemable noncontrolling interests in the Operating Partnership and DownREIT Partnership have a redemption feature and are marked to their redemption value. The redemption value is based on the fair value of the Company’s common stock at the redemption date, and therefore, is calculated based on the fair value of the Company’s common stock at the balance sheet date. Since the valuation is based on observable inputs such as quoted prices for similar instruments in active markets, redeemable noncontrolling interests in the Operating Partnership and DownREIT Partnership are classified as Level 2.

Financial Instruments Not Carried at Fair Value

At December 31, 2023, the fair values of cash and cash equivalents, restricted cash, accounts receivable, prepaids, real estate taxes payable, accrued interest payable, security deposits and prepaid rent, distributions payable and accounts payable approximated their carrying values because of the short term nature of these instruments. The estimated fair values of other financial instruments, which includes notes receivable and debt instruments, are classified in Level 3 of the fair value hierarchy due to the significant unobservable inputs that are utilized in their respective valuations.

  1. DERIVATIVES AND HEDGING ACTIVITY

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its debt funding and through the use of derivative financial instruments. Specifically, the Company may enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate F - 50

Table of Contents

UDR, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium.

The changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in Accumulated other comprehensive income/(loss), net on the Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the years ended December 31, 2023, 2022, and 2021, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt.

Amounts reported in Accumulated other comprehensive income/(loss), net on the Consolidated Balance Sheets related to derivatives that will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. Through December 31, 2024, the Company estimates that an additional $6.0 million will be reclassified as a decrease to Interest expense.

As of December 31, 2023, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (dollars in thousands):

**** Number of ****
Product Instruments Notional
Interest rate swaps and caps 6 $ 369,880

Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of GAAP. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. As of December 31, 2023, no derivatives not designated as hedges were held by the Company.

Credit-risk-related Contingent Features

The Company has agreements with its derivative counterparties that contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company’s default on the indebtedness.

The Company has certain agreements with some of its derivative counterparties that contain a provision where, in the event of default by the Company or the counterparty, the right of setoff may be exercised. Any amount payable to one party by the other party may be reduced by its setoff against any amounts payable by the other party. Events that give rise to default by either party may include, but are not limited to, the failure to pay or deliver payment under the derivative agreement, the failure to comply with or perform under the derivative agreement, bankruptcy, a merger without assumption of the derivative agreement, or in a merger, a surviving entity’s creditworthiness is materially weaker than the original party to the derivative agreement.

Contingencies

Litigation and Legal Matters

The Company is subject to various legal proceedings and claims arising in the ordinary course of business. The Company cannot determine the ultimate liability with respect to such legal proceedings and claims at this time. The Company believes that such liability, to the extent not provided for through insurance or otherwise, will not have a material adverse effect on our financial condition, results of operations or cash flows.

  1. REPORTABLE SEGMENTS

GAAP guidance requires that segment disclosures present the measure(s) used by the Chief Operating Decision Maker to decide how to allocate resources and for purposes of assessing such segments’ performance. UDR’s Chief Operating Decision Maker is comprised of several members of its executive management team who use several generally accepted industry financial measures to assess the performance of the business for our reportable operating segments.

UDR owns and operates multifamily apartment communities that generate rental and other property related income through the leasing of apartment homes to a diverse base of tenants. The primary financial measures for UDR’s apartment communities are rental income and net operating income (“NOI”). Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. NOI is defined as rental income less direct property rental expenses. Rental expenses include real estate taxes, insurance, personnel, utilities, repairs and maintenance, administrative and marketing. Excluded from NOI is property management expense, which is calculated as 3.25% of property revenue, and land rent. Property management expense covers costs directly related to consolidated property operations, inclusive of corporate management, regional supervision, accounting and other costs. UDR’s Chief Operating Decision Maker utilizes NOI as the key measure of segment profit or loss.

UDR’s two reportable segments are Same-Store Communities and Non-Mature Communities/Other:

Same-Store Communities represent those communities acquired, developed, and stabilized prior to January 1, 2022 and held as of December 31, 2023. A comparison of operating results from the prior year is meaningful as these communities were owned and had stabilized occupancy and operating expenses as of the beginning of the prior year, there is no plan to conduct substantial redevelopment activities, and the community is not classified as held for disposition within the current year. A community is considered to have stabilized occupancy once it achieves 90% occupancy for at least three consecutive months.

F - 53

Table of Contents

UDR, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2023

Non-Mature Communities/Other represent those communities that do not meet the criteria to be included in Same-Store Communities, including, but not limited to, recently acquired, developed and redeveloped communities, and the non-apartment components of mixed use properties.

Management evaluates the performance of each of our apartment communities on a Same-Store Community and Non-Mature Community/Other basis, as well as individually and geographically. This is consistent with the aggregation criteria under GAAP as each of our apartment communities generally has similar economic characteristics, facilities, services, and tenants. Therefore, the Company’s reportable segments have been aggregated by geography in a manner identical to that which is provided to the Chief Operating Decision Maker.

All revenues are from external customers and no single tenant or related group of tenants contributed 10% or more of UDR’s total revenues during the years ended December 31, 2023, 2022, and 2021.

The following is a description of the principal streams from which the Company generates its revenue:

Lease Revenue

Lease revenue related to leases is recognized on an accrual basis when due from residents or tenants in accordance with ASC 842, Leases. Rental payments are generally due on a monthly basis and recognized on a straight-line basis over the noncancellable lease term because collection of the lease payments was probable at lease commencement, inclusive of any periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of lease revenue on a straight-line basis over the lease term.

Lease revenue also includes all pass-through revenue from retail and residential leases and common area maintenance reimbursements from retail leases. These services represent non-lease components in a contract as the Company transfers a service to the lessee other than the right to use the underlying asset. The Company has elected the practical expedient under the leasing standard to not separate lease and non-lease components from its resident and retail lease contracts as the timing and pattern of revenue recognition for the non-lease component and related lease component are the same and the combined single lease component would be classified as an operating lease.

Other Revenue

Other revenue is generated by services provided by the Company to its retail and residential tenants and other unrelated third parties. Revenue is measured based on consideration specified in contracts with customers. The Company recognizes revenue when it satisfies a performance obligation by providing the services specified in a contract to the customer. These fees are generally recognized as earned.

Joint venture management and other fees

The Joint venture management and other fees revenue consists of management fees charged to our equity method joint ventures per the terms of contractual agreements and other fees. Joint venture fee revenue is recognized monthly as the management services are provided and the fees are earned or upon a transaction whereby the Company earns a fee. Joint venture management and other fees are not allocable to a specific reportable segment or segments.

The following table details rental income and NOI for UDR’s reportable segments for the years ended December 31, 2023, 2022, and 2021, and reconciles NOI to Net income/(loss) attributable to UDR, Inc. on the Consolidated Statements of Operations (dollars in thousands): F - 54

Exhibit 10.01 UDR, INC.

1999 LONG-TERM INCENTIVE PLAN

(AS AMENDED AND RESTATED FEBRUARY 19, 2024)

ARTICLE 1

PURPOSE

1.1GENERAL. The purpose of the UDR, Inc. 1999 Long-Term Incentive Plan (the “Plan”) is to promote the success, and enhance the value, of UDR, Inc. (the “Company”), by linking the personal interests of its employees, officers, consultants and directors to those of Company shareholders and by providing such persons with an incentive for outstanding performance. The Plan is further intended to provide flexibility to the Company in its ability to motivate, attract, and retain the services of employees, officers, consultants and directors upon whose judgment, interest, and special effort the successful conduct of the Company’s operation is largely dependent. Accordingly, the Plan permits the grant of incentive awards from time to time to selected employees, officers, consultants and directors.

ARTICLE 2

EFFECTIVE DATE

2.1EFFECTIVE DATE. For tax reasons, the Plan was approved by the Board of Directors in interim stages. First, the Board approved the Plan on March 9, 1999 as it relates to Awards of Restricted Stock and Performance Units only (the “First Effective Date”), and the Plan became effective as of the First Effective Date for the limited purpose of (i) making Awards of Restricted Stock on or prior to May 31, 1999 to non-officer employees of the Company and (ii) making cash Performance Unit Awards under ARTICLE 9 of the Plan with respect to a performance period beginning on January 1, 1999.

On January 25, 2000, the Board approved the Plan for the purpose of (i) making Awards of Restricted Stock on or prior to May 31, 2000 to non-officer employees of the Company,  (ii) making Awards of Restricted Stock on or prior to May 31, 2000 to certain officers of the Company from shares purchased by the Company on the open market, and (iii) making cash Performance Unit Awards under ARTICLE 9 of the Plan with respect to a performance period beginning on January 1, 2000 (the “Second Effective Date”).

On March 20, 2001, the Board approved the Plan as it relates to all types of Awards under the Plan (the “Third Effective Date”) and the Plan became fully effective as of the Third Effective Date. The Plan was approved by the shareholders of the Company on May 8, 2001.

5.4LIMITATION ON AWARDS.

(3)If the Participant terminates employment for any reason other than as provided in paragraph (4) or (5) below, the Incentive Stock Option shall lapse, unless it is previously exercised, three months after the Participant’s termination of employment; provided, however, that if the Participant’s employment is terminated by the Company for cause or by the Participant without the consent of the Company (in either case, as determined by the Company and communicated in writing to the Participant), the Incentive Stock Option shall (to the extent not previously exercised) lapse immediately.

(4)If the Participant terminates employment by reason of his Disability, the Incentive Stock Option shall lapse, unless it is previously exercised, one year after the Participant’s termination of employment.

(5)If the Participant dies while employed, or during the three-month period described in paragraph (3) or during the one-year period described in paragraph (4) and before the Option otherwise lapses, the Option shall lapse one year after the Participant’s death.

Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, limitations on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock). These restrictions may lapse separately or in combination at such times, under such circumstances, in such installments, upon the satisfaction of performance goals or otherwise, as the Committee determines at the time of the grant of the Award or thereafter.

10.3FORFEITURE. Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon termination of employment during the applicable restriction period or upon failure to satisfy a performance goal during the applicable restriction period, Restricted Stock that is at that time subject to restrictions shall be forfeited and reacquired by the Company; provided, however, that the Committee may provide in any Award Agreement that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part restrictions or forfeiture conditions relating to Restricted Stock.

14

​ ​

10.4CERTIFICATES FOR RESTRICTED STOCK. Restricted Stock granted under the Plan may be evidenced in such manner as the Committee shall determine.

ARTICLE 11

DIVIDEND EQUIVALENTS

11.1GRANT OF DIVIDEND EQUIVALENTS. The Committee is authorized to grant Dividend Equivalents to Participants subject to such terms and conditions as may be selected by the Committee. Dividend Equivalents shall entitle the Participant to receive payments equal to dividends with respect to all or a portion of the number of shares of Stock subject to an Award, as determined by the Committee. The Committee may provide that Dividend Equivalents be paid or distributed when accrued or be deemed to have been reinvested in additional shares of Stock, or otherwise reinvested. Dividend Equivalents shall not be granted with respect to Options or SARs. Dividend Equivalents granted with respect to Performance Units may not be paid except to the extent the underlying shares of Stock have been earned.

ARTICLE 12

OTHER STOCK-BASED AWARDS

12.1GRANT OF OTHER STOCK-BASED AWARDS. The Committee is authorized, subject to limitations under applicable law, to grant to Participants such other Awards that are payable in, valued in whole or in part by reference to, or otherwise based on or related to shares of Stock, as deemed by the Committee to be consistent with the purposes of the Plan, including without limitation shares of Stock awarded purely as a “bonus” and not subject to any restrictions or conditions, convertible or exchangeable debt securities, other rights convertible or exchangeable into shares of Stock, and Awards valued by reference to book value of shares of Stock or the value of securities of or the performance of specified Parents or Subsidiaries. The Committee shall determine the terms and conditions of such Awards.

ARTICLE 13

OTHER AWARDS

13.1GRANT OF OTHER CASH-BASED AWARDS. The Committee is authorized, subject to limitations under applicable law, to grant to Participants Awards that are denominated in cash and that may be settled in cash and/or shares of Stock, as deemed by the Committee to be consistent with the purposes of the Plan. The Committee shall determine the terms and conditions of such Awards.

15

​ 13.2LTIP UNITS. The Committee is authorized to grant LTIP Units to Participants in such amounts and subject to such terms and conditions as may be selected by the Committee; provided, however, that LTIP Units may only be issued to a Participant for the performance of services to or for the benefit of the Partnership (a) in the Participant’s capacity as a partner of the Partnership, (b) in anticipation of the Participant becoming a partner of the Partnership, or (c) as otherwise determined by the Committee, provided that the LTIP Units are intended to constitute “profits interests” within the meaning of the Code, including, to the extent applicable, Revenue Procedure 93-27, 1993-2 C.B. 343 and Revenue Procedure 2001-43, 2001-2 C.B. 191. The Committee shall specify the conditions and dates upon which the LTIP Units shall vest and become nonforfeitable. LTIP Units shall be subject to the terms and conditions of the Partnership Agreement and such other restrictions, including restrictions on transferability (including by redemption or conversion), as the Committee may impose. These restrictions may lapse separately or in combination at such times, pursuant to such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter.

ARTICLE 14

PROVISIONS APPLICABLE TO AWARDS

14.1STAND-ALONE, TANDEM, AND SUBSTITUTE AWARDS. Awards granted under the Plan may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for, any other Award granted under the Plan. If an Award is granted in substitution for another Award, the Committee may require the surrender of such other Award in consideration of the grant of the new Award. Notwithstanding the foregoing, as provided in Section 16.1, except as provided in Section 15.1, without the consent of the shareholders, an Award may not be granted in substitution of another Award if the effect is to replace an Option or Stock Appreciation Right with an Award with a lower exercise or grant price. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or at a different time from the grant of such other Awards.

14.2EXCHANGE PROVISIONS. The Committee may at any time offer to exchange or buy out any previously granted Award for a payment in cash, Stock, or another Award (subject to Section 15.1), based on the terms and conditions the Committee determines and communicates to the Participant at the time the offer is made, and after taking into account the tax, securities and accounting effects of such an exchange. Notwithstanding the foregoing, as provided in Section 16.1, except as provided in Section 15.1, without the consent of the shareholders an Award may not be exchanged or bought out if the effect is to lower the exercise price of the Option or the grant price of the Stock Appreciation Right.

14.3TERM OF AWARD. The term of each Award shall be for the period as determined by the Committee, provided that in no event shall the term of any Incentive Stock Option or a Stock Appreciation Right granted in tandem with the Incentive Stock Option exceed a period of ten years from the date of its grant (or, if Section 7.2(e) applies, five years from the date of its grant).

14.4FORM OF PAYMENT FOR AWARDS. Subject to the terms of the Plan and any applicable law or Award Agreement, payments or transfers to be made by the Company or a Parent

16

​ or Subsidiary on the grant or exercise of an Award may be made in such form as the Committee determines at or after the time of grant, including without limitation, cash, Stock, other Awards, or other property, or any combination, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case determined in accordance with rules adopted by, and at the discretion of, the Committee.

14.5LIMITS ON TRANSFER. No right or interest of a Participant in any unexercised or restricted Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Company or a Parent or Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or a Parent or Subsidiary.  No unexercised or restricted Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution or, except in the case of an Incentive Stock Option, pursuant to a domestic relations order that would satisfy Section 414(p)(1)(A) of the Code if such Section applied to an Award under the Plan; provided, however, that the Committee may (but need not) permit other transfers where the Committee concludes that such transferability (i) does not result in accelerated taxation, (ii) does not cause any Option intended to be an incentive stock option to fail to be described in Code Section 422(b), and (iii) is otherwise appropriate and desirable, taking into account any factors deemed relevant, including without limitation, any state or federal tax or securities laws or regulations applicable to transferable Awards.

14.6BENEFICIARIES. Notwithstanding Section 14.5, a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights under the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If no beneficiary has been designated or survives the Participant, payment shall be made to the Participant’s estate. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided the change or revocation is filed with the Committee.

14.7STOCK CERTIFICATES. All Stock issued under the Plan is subject to any stop- transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal or state securities laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate or issue instructions to the transfer agent to reference restrictions applicable to the Stock.

14.8ACCELERATION UPON DEATH OR DISABILITY. Notwithstanding any other provision in the Plan and unless otherwise provided in any Participant’s Award Agreement, upon the Participant’s death or Disability during his employment or service as a director or consultant, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. Any Option or Stock Appreciation Rights Awards shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award Agreement. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options.

17

​ 14.9ACCELERATION UPON RETIREMENT. Notwithstanding any other provision in the Plan and unless otherwise provided in any Participant’s Award Agreement, upon the Participant’s Retirement, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. Any Option or Stock Appreciation Rights Awards shall thereafter remain exercisable until the original expiration date of the Award. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options.

14.10CHANGE OF CONTROL. With respect to Awards granted prior to November 12, 2020, except as otherwise provided in the Award Agreement, upon the occurrence of a Change of Control, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. With respect to Awards granted on or after November 12, 2020, in the event that a Participant’s employment or other service relationship with the Company is terminated by the Company without Cause or by the Participant for Good Reason, in each case on or within twelve (12) months following the date of a Change of Control, any outstanding Awards then held by such affected Participant which are unexercisable or otherwise unvested shall automatically be deemed exercisable or otherwise vested, as the case may be, as of immediately prior to such termination of employment or other service relationship; provided, that in the event the vesting or exercisability of any Award would otherwise be subject to the achievement of performance conditions, such Award that shall become fully vested and immediately exercisable based on the higher of (a) assumed achievement of performance at the target level as set forth in the related Award Agreement or (b) actual performance, to the extent measurable. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options.

14.11EFFECT OF ACCELERATION. In the event of a Change of Control, the Committee may provide (i) (other than in the event of a Change of Control defined in Section 3.1(f)(4) or 3.1(f)(6)) that the Award will expire after a designated period of time to the extent not then exercised, (ii) that the Award will be settled in cash rather than Stock, (iii) that the Award will be assumed by another party to the transaction or otherwise be equitably converted in connection with such transaction, or (iv) any combination of the foregoing. The Committee’s determination need not be uniform and may be different for different Participants whether or not such Participants are similarly situated.

14.12MINIMUM VESTING PERIOD.  Awards granted on or after November 12, 2020 shall not vest over a period of less than one (1) year from the date on which the Award is granted; provided that the following Awards shall not be subject to the foregoing minimum vesting requirement: any (i) awards granted by another entity that are assumed by the Company or awards granted in substitution for outstanding awards granted by another entity, (ii) Awards to directors that vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year’s annual meeting, and (iii) any additional Awards the Committee may grant, up to a maximum of five percent (5%) of the available share reserve authorized for issuance under the Plan; and provided, further, that the foregoing restriction does not apply to the Committee’s discretion to provide for accelerated exercisability or vesting of any Award, including in cases of Retirement, death, Disability or a Change of Control.

18

​ ​

14.13PERFORMANCE GOALS. The Committee may determine that any Award granted pursuant to this Plan to a Participant (including, but not limited to, Participants who are Covered Employees) shall be determined solely on the basis of (a) the achievement by the Company or a Parent or Subsidiary of a specified target return, or target growth in return, on equity or assets, (b) the Company’s total shareholder return (stock price appreciation plus reinvested dividends) relative to a defined comparison group or target over a specific performance period or periods, (c) the Company’s stock price, (d) the achievement by an individual, group of individuals, the Company, or a business unit or division of the Company, Parent or Subsidiary of a specified target, or target growth in, relative to a defined comparison group or otherwise, revenues, net income or earnings per share, or including but not limited to, targets based, in whole or part, on funds from operations (adjusted or otherwise), net asset value, asset quality, same store revenue growth, same store expense growth, net operating income (including, but not limited to, same store net operating income), operating margin, development or redevelopment activities (including, but not limited to, development or redevelopment funds from operations), lease-up activities, funds from operations pay-out ratio, net financial capabilities (including, but not limited to, with respect to cash, liquid receivables, available lines of credit or debt maturities), leverage ratio, balance sheet, credit rating, debt maturity, liquidity, credit capacity, fixed charges (including, but not limited to, fixed charge ratios), debt, net debt, earnings before or after taxes, interest, depreciation, or amortization, transactions (including, but not limited to, consummation of acquisitions, sales, joint ventures or financings), portfolio enhancement, mitigation plans or strategies; (e) the achievement of objectively determinable goals with respect to service or product delivery, service or product quality, sales or marketing (including, but not limited to, web traffic, technology penetration, web platform (including, but not limited to, social networking platform), online leasing, concierge services or call centers), customer retention or satisfaction, expansion of revenue or income streams, sourcing of low cost capital, operational efficiencies, dividend growth, earnings multiple improvement, meeting budgets, staffing, retention, growth, development, engagement, integration, succession and/or reviewing performance of employees, business or strategic plans, investor communications or relations, compliance (including, but not limited to, with respect to accounting, tax, external or regulatory filings, internal financial reporting, audits (including, but not limited to, internal audits) or contract policies), financial planning or analysis; (f) any other goals or objectives selected by the Committee or (g) any combination or subset of the goals set forth in (a) through (f) above. If an Award is made on such basis, the Committee shall establish goals at such time as the Committee may determine and the Committee has the right for any reason to reduce (but not increase) the Award, notwithstanding the achievement of a specified goal. Any payment of an Award granted with performance goals shall be conditioned on the written certification of the Committee in each case that the performance goals and any other material conditions were satisfied.

14.14TERMINATION OF EMPLOYMENT. Whether military, government or other service or other leave of absence shall constitute a termination of employment shall be determined in each case by the Committee at its discretion, and any determination by the Committee shall be final and conclusive. A termination of employment shall not occur (i) in a circumstance in which a Participant transfers from the Company to one of its Parents or Subsidiaries, transfers from a Parent or Subsidiary to the Company, or transfers from one Parent or Subsidiary to another Parent or Subsidiary, or (ii) in the discretion of the Committee as specified at or prior to such occurrence, in the case of a spin-off, sale or disposition of the Participant’s employer from the Company or any Parent or Subsidiary. To the extent that this provision causes Incentive Stock Options to extend

19

​ beyond three months from the date a Participant is deemed to be an employee of the Company, a Parent or Subsidiary for purposes of Section 424(f) of the Code, the Options held by such Participant shall be deemed to be Non- Qualified Stock Options.

ARTICLE 15

CHANGES IN CAPITAL STRUCTURE

15.1GENERAL. In the event of a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination or exchange of shares), the authorization limits under Section 5.1 and 5.4 shall be adjusted proportionately, and the Committee shall adjust Awards to preserve the benefits or potential benefits of the Awards. Action by the Committee shall include: (i) adjustment of the number and kind of shares or other securities which may be delivered under the Plan; (ii) adjustment of the number and kind of shares or other securities subject to outstanding Awards; (iii) adjustment of the exercise price of outstanding Awards; and (iv) any other adjustments that the Committee determines to be equitable. Without limiting the foregoing, in the event a stock dividend or stock split is declared upon the Stock, the authorization limits under Section 5.1 and 5.4 shall be increased proportionately, and the shares of Stock or other securities then subject to each Award shall be increased proportionately without any change in the aggregate purchase price therefor.

ARTICLE 16

AMENDMENT, MODIFICATION AND TERMINATION

16.1AMENDMENT, MODIFICATION AND TERMINATION. The Board or the Committee may, at any time and from time to time, amend, modify or terminate the Plan without shareholder approval; provided, however, that the Board or Committee may condition any amendment or modification on the approval of shareholders of the Company if such approval is necessary or deemed advisable with respect to tax, securities or other applicable laws, policies or regulations.

16.2AWARDS PREVIOUSLY GRANTED. At any time and from time to time, the Committee may amend, modify or terminate any outstanding Award without approval of the Participant; provided, however, that, subject to the terms of the applicable Award Agreement, such amendment, modification or termination shall not, without the Participant’s consent, reduce or diminish the value of such Award determined as if the Award had been exercised, vested, cashed in or otherwise settled on the date of such amendment or termination, and provided further that, except as provided in Section 15.1 or otherwise with the consent of the shareholders, the exercise price of any Option or the grant price of any Stock Appreciation Right may not be reduced. No termination, amendment, or modification of the Plan shall adversely affect any Award previously granted under the Plan, without the written consent of the Participant.

20

ARTICLE 17

GENERAL PROVISIONS

17.1NO RIGHTS TO AWARDS. No Participant or eligible participant shall have any claim to be granted any Award under the Plan, and neither the Company nor the Committee is obligated to treat Participants or eligible participants uniformly.

17.2NO SHAREHOLDER RIGHTS. No Award gives the Participant any of the rights of a shareholder of the Company unless and until shares of Stock are in fact issued to such person in connection with such Award.

17.3WITHHOLDING. The Company or any Parent or Subsidiary shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the Plan. With respect to withholding required upon any taxable event under the Plan, the Committee may, at the time the Award is granted or thereafter, require or permit that any such withholding requirement (up to the maximum statutory withholding rates in the applicable jurisdiction) be satisfied, in whole or in part, by withholding from the Award shares of Stock, all in accordance with such procedures as the Committee establishes.

17.4NO RIGHT TO CONTINUED SERVICE. Nothing in the Plan or any Award Agreement shall interfere with or limit in any way the right of the Company or any Parent or Subsidiary to terminate any Participant’s employment or status as an officer, consultant or director at any time, nor confer upon any Participant any right to continue as an employee, officer, consultant or director of the Company or any Parent or Subsidiary.

17.5UNFUNDED STATUS OF AWARDS. The Plan is intended to be an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company or any Parent or Subsidiary.

17.6INDEMNIFICATION. To the extent allowable under applicable law, each member of the Committee shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which such member may be a party or in which he may be involved by reason of any action or failure to act under the Plan and against and from any and all amounts paid by such member in satisfaction of judgment in such action, suit, or proceeding against him provided he gives the Company an opportunity, at its own expense, to handle and defend the same before he undertakes to handle and defend it on his own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

21

​ 17.7RELATIONSHIP TO OTHER BENEFITS. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or benefit plan of the Company or any Parent or Subsidiary unless provided otherwise in such other plan.

17.8EXPENSES. The expenses of administering the Plan shall be borne by the Company and its Parents or Subsidiaries.

17.9TITLES AND HEADINGS. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

17.10GENDER AND NUMBER. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include the plural.

17.11FRACTIONAL SHARES. No fractional shares of Stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up.

17.12GOVERNMENT AND OTHER REGULATIONS. The obligation of the Company to make payment of awards in Stock, LTIP Units or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Company shall be under no obligation to register under the 1933 Act, or any state securities act, any of the shares of Stock or LTIP Units issued in connection with the Plan. The shares or LTIP Units issued in connection with the Plan may in certain circumstances be exempt from registration under the 1933 Act, and the Company may restrict the transfer of such shares or LTIP Units in such manner as it deems advisable to ensure the availability of any such exemption.

17.13GOVERNING LAW. To the extent not governed by federal law, the Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the Commonwealth of Virginia.

17.14ADDITIONAL PROVISIONS. Each Award Agreement may contain such other terms and conditions as the Committee may determine; provided that such other terms and conditions are not inconsistent with the provisions of this Plan. The foregoing is hereby acknowledged as being the UDR, Inc. 1999 Long-Term Incentive Plan as amended and restated as approved on December 1, 2023 to be effective February 19, 2024.

Exhibit 97.1

UDR, INC.

RECOUPMENT POLICY

In the event of any required accounting restatement of the financial statements of UDR, Inc. (the “Company”) due to the material noncompliance of the Company with any financial reporting requirement under the applicable U.S. federal securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (a “Restatement”), the Company shall recover reasonably promptly from any person, who is or was an “Executive Officer,” as such term is defined in Rule 10D-1 adopted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 303A.14 of the New York Stock Exchange (“NYSE”) Listed Company Manual, of the Company (each, a “Covered Person”) the amount of any “Erroneously Awarded Incentive-Based Compensation” (as defined below). The effective date of Section 303A.14 of the NYSE Listed Company Manual is October 2, 2023 (the “Listing Standard Effective Date”). The effective date of this Policy is December 1, 2023 (the “Policy Effective Date”). As of the Policy Effective date, this Policy will supersede and replace the Company’s Recoupment of Performance-Based Incentives policy.

The amount of Incentive-Based Compensation (as defined below) that must be recovered from a Covered Person pursuant to the immediately preceding paragraph is the amount of “Recoverable Incentive-Based Compensation” (as defined below) received by a Covered Person that exceeds the amount of Recoverable Incentive-Based Compensation that otherwise would have been received had it been determined based on the restated amounts, computed without regard to any taxes paid (referred to as the “Erroneously Awarded Incentive-Based Compensation”). For Recoverable Incentive-Based Compensation based on stock price or total shareholder return, where the amount of Erroneously Awarded Incentive-Based Compensation is not subject to mathematical recalculation directly from the information in a Restatement, the amount must be based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return, as applicable, upon which the Recoverable Incentive-Based Compensation was received, and the Company must maintain documentation of that reasonable estimate and provide such documentation to the NYSE.^^For the purposes of this Policy, Recoverable Incentive-Based Compensation will be deemed to be received in the fiscal period during which the Financial Reporting Measure (as defined below) specified in the applicable Incentive-Based Compensation award is attained, even if the payment or grant occurs after the end of that period.

For purposes of this Policy, “Incentive-Based Compensation” means any compensation that is granted, earned or vested based wholly or in part upon the attainment of a “Financial Reporting Measure,” which means a measure that is determined and presented in accordance with Generally Accepted Accounting Principles which are used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measure. Stock price and total shareholder return are also Financial Reporting Measures for this purpose. For avoidance of doubt, a Financial Reporting

1

Measure need not be presented within the Company’s financial statements or included in a filing with the U.S. Securities and Exchange Commission (the “SEC”).

For purposes of this Policy, “Recoverable Incentive-Based Compensation” means all Incentive-Based Compensation received on or after the Listing Standard Effective Date by a Covered Person: (i) after beginning service as an executive officer; (ii) who served as an Executive Officer at any time during the performance period for the Incentive-Based Compensation; (iii) while the Company has a class of securities listed on a national securities exchange or a national securities association; and (iv) during the three completed fiscal years immediately preceding the date that the Company is required to prepare a Restatement, including any applicable transition period that results from a change in the Company’s fiscal year within or immediately following those three completed fiscal years as specified in Rule 10D-1 under the Exchange Act and Section 303A.14 of the NYSE Listed Company Manual. For this purpose, the Company is deemed to be required to prepare a Restatement on the earlier of: (i) the date the Company’s Board of Directors (the “Board”), or the Company’s officers authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement; or (ii) the date a court, regulator or other legally authorized body directs the Company to prepare a Restatement. The Company’s obligation to recover Erroneously Awarded Incentive-Based Compensation is not dependent on if or when the restated financial statements are filed with the SEC.

The Company shall recover the Erroneously Awarded Incentive-Based Compensation from Covered Persons unless the Compensation and Management Development Committee of the Board (the “Compensation Committee”), or, in the absence of the Compensation Committee, a majority of the independent directors serving on the Board, determines that recovery is impracticable because: (i) the direct expense to a third party to assist in enforcing this Policy would exceed the amount of Erroneously Awarded Incentive-Based Compensation; provided that, the Company must make a reasonable attempt to recover the Erroneously Awarded Incentive-Based Compensation before concluding that recovery is impracticable, document such reasonable attempt to recover the Erroneously Awarded Incentive-Based Compensation and provide such documentation to the NYSE; or (ii) recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the applicable requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

In no event will the Company indemnify any Covered Person for any amounts that are recovered under this Policy. This Policy is in addition to (and not in lieu of) any right of repayment, forfeiture or right of offset against any employees that is required pursuant to any statutory repayment requirement (regardless of whether implemented at any time prior to or following the adoption or amendment of this Policy), including Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”). Any amounts paid to the Company pursuant to Section 304 of the Sarbanes-Oxley Act shall be considered in determining any amounts recovered under this Policy.

2

If a Covered Person fails to repay Erroneously Awarded Incentive-Based Compensation that is owed to the Company under this Policy, the Company shall take all appropriate action to recover such Erroneously Awarded Incentive-Based Compensation from the Covered Person. The application and enforcement of this Policy does not preclude the Company from taking any other action to enforce a Covered Person’s obligations to the Company, including termination of employment or institution of legal proceedings. Nothing in this Policy restricts the Company from seeking recoupment under any other compensation recoupment policy or any other applicable provisions in plans, agreements, awards or other arrangements that contemplate the recoupment of compensation from a Covered Person. The terms of this Policy shall be binding and enforceable against all Covered Persons subject to this Policy and their beneficiaries, heirs, executors, administrators or other legal representatives. If any provision of this Policy or the application of such provision to any Covered Person shall be adjudicated to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Policy, and the invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to render any such provision (or the application of such provision) valid, legal or enforceable.

Each Covered Person shall sign and return to the Company, within 30 calendar days following the later of (i) the Policy Effective Date or (ii) the date the individual becomes a Covered Person, the Acknowledgement Form attached hereto as Exhibit A, pursuant to which the Covered Person agrees to be bound by, and to comply with, the terms and conditions of this Policy.

This Policy shall be interpreted in a manner that is consistent with Rule 10D-1 under the Exchange Act, Section 303A.14 of the NYSE Listed Company Manual and any related rules or regulations adopted by the SEC or the NYSE (the “Applicable Rules”), as well as any other applicable law. To the extent the Applicable Rules require recovery of Incentive-Based Compensation in additional circumstances besides those specified above, nothing in this Policy shall be deemed to limit or restrict the right or obligation of the Company to recover Erroneously Awarded Incentive-Based Compensation to the fullest extent required by the Applicable Rules.
