ITEM 1A. RISK FACTORS

Our operations involve various risks that could have adverse consequences, including those described below. This Item 1A. includes forward-looking statements. You should refer to our discussion of the qualifications and limitations on forward-looking statements in this Form 10-K.

Risks related to investments through acquisitions, construction, development, and joint ventures

Development, redevelopment and construction risks could affect our profitability. We intend to continue to develop and redevelop apartment communities. These activities can include long planning and entitlement timelines and can involve complex and costly activities, including significant environmental remediation or construction work in high-density urban areas. These activities may expose us to the following risks, among others:

•we have recently abandoned, and may in the future abandon, opportunities that we have already begun to explore for a number of reasons, including changes in local market conditions or increases in construction or financing costs or we may impair land held for development, and as a result, we may fail to recover expenses already incurred in exploring those opportunities;

•occupancy rates and rents at a community may fail to meet our original expectations for a number of reasons, including changes in market and economic conditions beyond our control and the development by competitors of competing communities;

•we may be unable to obtain, or experience delays in obtaining, necessary zoning, occupancy or other required governmental or third party permits and authorizations, which could result in increased costs, or the delay or abandonment of opportunities;

•we may incur costs that exceed our original estimates due to increased material, labor or other costs or supply chain disruptions, including as a result of tariffs or changes in immigration laws or their enforcement, which could impact our overall return from our development, redevelopment or construction activity;

•we may be unable to complete construction of a community on schedule or for the originally projected cost resulting in increased construction and financing costs;

•we may incur liabilities to third parties during the development process, for example, in connection with managing existing improvements on the site prior to tenant terminations and demolition (such as commercial space) or in connection with providing services to third parties (such as the construction of shared infrastructure or other improvements); and

•we may incur liability if our communities are not constructed in compliance with the accessibility provisions of the Americans with Disabilities Acts, the Fair Housing Act or other federal, state or local requirements. Noncompliance could result in imposition of fines, an award of damages to private litigants and a requirement that we undertake structural modifications to remedy the noncompliance.

Refer to our "Risks related to liquidity and financing" section below for additional construction and development risks related to financing.

Attractive investment opportunities may not be available, which could adversely affect our profitability. We expect that other real estate investors, including insurance companies, pension and investment funds, other REITs and other well-capitalized investors, will compete with us to acquire existing properties and to develop new properties. This competition could increase prices for properties of the type we would likely pursue and adversely affect our profitability for new investments.

Acquisitions may not yield anticipated results. Our business strategy of acquiring communities involves the following risks, among others: (i) acquisitions may not perform as we expected; (ii) our estimate of the costs of operating, repositioning or redeveloping an acquisition may be inaccurate; and (iii) acquisitions may subject us to unknown liabilities.

Failure to succeed in new markets, or with new brands and community formats, or in activities other than the development, ownership and operation of residential rental communities may have adverse consequences. We have engaged, and may continue from time to time to engage in development, acquisition and operating activity outside of our pre-existing market areas. Our historical experience in our existing markets in developing, owning and operating rental communities does not ensure that we will be able to operate successfully in new markets. We may be exposed to a variety of risks when we enter a new market, including an inability to accurately evaluate local apartment market conditions and an inability to obtain land for development or to identify appropriate acquisition opportunities. In order to more rapidly expand in our new markets, we have relied on third party developers to source and manage developments and on third party general contractors to manage construction more than we have in our existing markets. Relying on third parties to assist with and/or oversee development and

construction creates additional and different risks than when we manage these activities directly, including that the third party may not perform to our standards, may breach contractual arrangements, or may incur liquidity constraints.

We also may engage or have an interest in for-sale activity, such as the sale of our remaining residential condominium at The Park Loggia, a mixed-use development located in New York, New York. We may be unsuccessful at developing real estate with the intent to sell or in selling condominiums at originally underwritten values, or at all, as a disposition strategy for an asset, which could have an adverse effect on our results of operations.

We provide, through our internally operated shared service center, various back-office, financial administrative support services to a third party for a fee, and we may in the future provide such services to other third parties. There can be no assurance that we will be successful in providing such services, and the provision of such services creates additional sources of risk and potential liability for us with respect to the professional commitments and service levels we undertake when providing such services.

We are exposed to risks associated with investment in technology and environmentally focused venture funds and companies. We have invested in, and may in the future invest in, venture funds that invest in companies seeking innovation through new processes and the application of technology to property operations, development, construction and energy management. We have also invested directly in, and may in the future invest directly in, companies that engage in these activities. While such investments give us a greater understanding of new and emerging technologies, such investments involve risks, including the possibility that our investments will decline substantially in value.

Our investments in technology companies, or in funds that invest in technology companies, are generally held through TRSs pursuant to which we will incur taxable gains upon the disposition of our interests. In addition, the value of these investments may be volatile and declines in value may impact our reported income even if we do not sell the investment.

We are exposed to risks associated with investment in, and management of, joint ventures. At times we invest directly and indirectly in real estate as a partner or a co-venturer with other investors. Joint venture investments (including investments through partnerships or limited liability companies) involve risks, including the possibility that our partner might become insolvent or otherwise refuse to make capital contributions when due; that we may be responsible to our partner for indemnifiable losses or the debt and obligations of an investment; that our investments may lose all or some of their value; that our partner might have business goals that are inconsistent with ours which may result in the venture or investment being unable to implement certain decisions that we consider beneficial; that our partner may be in a position to take action or withhold consent contrary to our instructions or requests; that, in cases where we are the general partner or managing member, our partners holding a majority of the equity interests may remove us from such role in certain cases involving cause; and that we may be liable and/or our status as a REIT may be jeopardized if either the investments, or the REIT entities associated with the investments, fail to comply with various tax or other regulatory matters. Frequently, we and our partner may each have the right to trigger a buy-sell or similar arrangement that could cause us to sell our interest, acquire our partner's interest or force a sale of the asset, which could occur at a time when we otherwise would not have initiated such a transaction or on terms that are not most advantageous to us.

Mezzanine debt and preferred equity investments could cause us to incur expenses, which could adversely affect our results of operations. We make mezzanine loans to borrowers and obtain preferred equity interests in projects owned by third party sponsors as part of our SIP. Some of these instruments may have some recourse to their borrower or sponsor, while others are limited to the collateral securing the loan or the right to remove the sponsor as manager of the venture in preferred equity investments. In the event of a default under these obligations, we may elect to take possession of the collateral securing these interests, or remove a sponsor from management of a preferred equity investment. Borrowers of mezzanine loans may contest our enforcement actions, including foreclosure, assignment in lieu of foreclosure, or other remedies, and sponsors may contest our removal actions. In addition, borrowers and sponsors may seek bankruptcy protection against such enforcement and/or bring claims for lender liability in response to actions to enforce their obligations to us. Declines in the value of the underlying properties may prevent us from realizing an amount equal to our investment upon foreclosure or other remedies even if we make substantial improvements or repairs to maximize such properties' investment potential.

We cannot be certain that our estimate of future credit losses will be adequate over time because of unanticipated adverse changes in the economy or events adversely affecting specific properties, assets, tenants, borrowers, industries in which our tenants and borrowers operate or markets in which our tenants and borrowers or their properties are located. The ultimate resolutions may differ from our expectation, and we could suffer losses that would have a material adverse effect on our financial performance, the trading price of our securities and our ability to pay dividends and distributions.

We are exposed to risks associated with real estate assets that are subject to ground leases that may restrict our ability to finance, sell or otherwise transfer our interests in those assets, limit our use and expose us to loss if such agreements are breached by us or terminated. We own assets that are subject to long-term ground leases. These ground leases may impose limitations on our use or improvement of the properties, restrict our ability to finance, sell or otherwise transfer our interests or restrict the leasing of the properties. These restrictions may limit our ability to timely sell or exchange the properties, impair the properties’ value or negatively impact our ability to operate the properties. In addition, we could lose our interests in the properties if the ground leases are breached by us, terminated or lapse. As we get closer to the lease termination dates, the values of the properties could decrease if we are unable to agree upon an extension of the lease with the lessor. Certain of these ground leases have payments subject to annual escalations and/or periodic fair market value adjustments which could adversely affect our financial condition or results of operations.

Land we hold with no current intent to develop may be subject to future impairment charges. We own land parcels that we do not currently intend to develop. As discussed in Item 2. "Properties—Other Land and Real Estate Assets," in the event that the fair market value, less the cost to dispose of a parcel, changes such that it is less than the carrying basis of the parcel, we would be subject to an impairment charge, which would reduce our net income.

Our various technology-related initiatives to improve our operating margins and customer experience may fail to perform as expected and may expose us to additional risks. We have developed and may continue to develop initiatives that are intended to serve our customers better and operate more efficiently, including "smart home" technology; use of AI in correspondence with prospective, current and prior residents; and self-service options that are accessible to residents through smart devices or otherwise. Such initiatives have involved and may continue to involve our employees 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 expected, which could adversely affect our business, results of operations, cash flows and financial condition. Furthermore, future regulations could impose restrictions on the use of these technologies or require us to implement costly compliance measures. Competition from companies employing technology-related initiatives more effectively could also negatively impact our business. Finally, public perception of new technologies (including AI), such as concerns about data privacy and algorithmic bias, could affect customer acceptance of technology-driven services, which could harm our reputation and business.

Risks related to liquidity and financing

Capital and credit market conditions may adversely affect our access to various sources of capital and/or the cost of capital, which could impact our business activities, dividends, earnings and common stock price, among other things. In periods when the capital and credit markets experience significant volatility, the amounts, sources and cost of capital available to us may be adversely affected. We use external financing as one source of capital to fund construction and to refinance indebtedness as it matures. If sufficient sources of external financing are not available to us on cost-effective terms, we could be forced to limit our development and redevelopment activity and/or take other actions to fund our business activities and repayment of debt, such as selling assets, reducing our cash dividend or issuing equity or debt securities. If we are able and/or choose to access capital at a higher cost than we have experienced in recent years, our earnings per share and cash flows could be adversely affected. In addition, the price of our common stock may fluctuate significantly and/or decline in a high interest rate environment or a volatile economic environment, or if we dilute the interest of stockholders by issuing additional equity. Further, events involving limited liquidity, defaults, non-performance or other adverse developments that affect the lenders under our Credit Facility, the dealers under our Commercial Paper Program, financial institutions where we have deposits, 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 at reasonable terms or at all or may cause us or our transactional counterparties to be unable to complete transactions as intended, all of which could have a material adverse effect on our financial condition and results of operations.

Insufficient cash flow could affect our debt financing and create refinancing risk. We are subject to the risks associated with debt financing, including the risk that our available cash will be insufficient to meet required payments of principal and interest on our debt. For us to continue to qualify as a REIT, we are required to annually distribute dividends generally equal to at least 90% of our REIT taxable income, which limits the amount of our cash flow available to meet required principal and interest payments. The principal outstanding balance on a portion of our debt will not be fully amortized prior to its maturity. We cannot assure you that we will have sufficient cash flows available to make all required principal payments. Therefore, we expect that we will generally need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that a refinancing will not be done on as favorable terms; either of these outcomes could have a material adverse effect on our financial condition and results of operations.

Rising interest rates could increase interest costs and could affect the market price of our common stock, and efforts to hedge such risk could be ineffective and cause us to incur additional costs. Interest rates have increased in recent years, and may increase further.If interest rates maintain their existing levels or further increase, our interest costs on variable rate debt will rise, and our interest costs on newly issued fixed rate debt may be higher than on our existing debt, unless in each case we have hedged the risk of rising interest rates. In addition, an increase in market interest rates may lead purchasers of our common stock to demand a greater annual dividend yield, which could adversely affect the market price of our common stock.

We may use interest rate derivatives to manage our exposure to fluctuations in interest rates, such as by entering into interest rate contracts. For example, when we anticipate issuing debt securities, we may seek to limit our exposure to fluctuations in interest rates prior to debt issuance by entering into interest rate hedging contracts. Although these agreements may partially protect against rising interest rates, they also may reduce the benefits to us if interest rates decline. The interest rate derivatives we use, primarily to manage interest rate risk for our anticipated debt issuance activity, could result in a material charge to earnings if we do not issue the anticipated debt, or are otherwise unsuccessful in our hedging activities. In addition, our use of hedging arrangements may expose us to additional risks, including a risk that a counterparty to a hedging arrangement may default on the contract. There can be no assurance that our hedging activities will be effective at reducing the risks associated with interest rate fluctuations.

Bond financing and zoning and other compliance requirements could limit our income, restrict the use of communities and cause favorable financing to become unavailable. We have financed some of our apartment communities with obligations issued by local government agencies because the interest paid to the holders of this debt is generally exempt from federal income taxes, which typically provides a more favorable interest rate for us. These obligations are commonly referred to as "tax-exempt bonds" and generally must be secured by mortgages on our communities. As a condition to obtaining (i) tax-exempt financing, (ii) favorable zoning or (iii) an agreement relating to property taxes in some jurisdictions, we will commit to make some of the apartments in a community available to households whose income does not exceed certain thresholds (e.g., 50% or 80% of area median income), or who meet other qualifying tests. As of December 31, 2024, 4.1% of our apartment homes at current operating communities were under income limitations such as these. These commitments, which may or may not expire, may limit our ability to raise rents, adversely affecting the value of communities subject to these restrictions. If we fail to observe these commitments, we could lose benefits (such as reduced property taxes) or face liabilities including liability for the benefits we received under tax exempt bonds, tax credits or agreements related to property taxes.

Our tax-exempt bonds may require us to obtain a guarantee from a financial institution of payment of the principal and interest on the bonds, such as a letter of credit, surety bond, guarantee agreement or other additional collateral. If the financial institution defaults in its guarantee obligations, or if we are unable to renew the applicable guarantee or otherwise post satisfactory collateral, a default will occur and the community could be foreclosed upon if we do not redeem the tax exempt bonds.

Risks related to indebtedness. We have a Credit Facility and Commercial Paper Program with a syndicate of commercial banks as well as secured and unsecured notes. Our organizational documents do not limit the amount or percentage of indebtedness that may be incurred. Accordingly, subject to compliance with outstanding debt covenants, we could incur more debt, resulting in an increased risk of default on our obligations and an increase in debt service requirements that could adversely affect our financial condition and results of operations.

The mortgages on properties that are subject to secured debt, our Credit Facility, Commercial Paper Program and the indentures under which a substantial portion of our debt was issued contain customary restrictions, requirements and other limitations, as well as certain financial and operating covenants including maintenance of certain financial ratios. Maintaining compliance with these restrictions could limit our flexibility. A default in these requirements, if uncured, could result in a requirement that we repay indebtedness, which could materially adversely affect our liquidity and increase our financing costs. Refer to Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" for further discussion.

A substantial portion of our debt is subject to prepayment penalties or premiums that we will be obligated to pay in the event that we elect to prepay the debt prior to the earlier of (i) its stated maturity or (ii) another stated date. If we elect to prepay a significant amount of outstanding debt, our prepayment penalties or payments under these provisions could materially adversely affect our results of operations.

Failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity and access to capital markets. There are two major debt rating agencies that routinely evaluate and rate our debt. Their ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, amount of real estate under development, and sustainability of cash flow and earnings, among other factors. If market conditions change, 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.

The form, timing and/or amount of dividend distributions in future periods may vary and be impacted by our revenue generation, other liquidity needs and economic and other considerations. The form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on our rental revenue, actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

We may experience barriers to selling apartment communities that could limit financial flexibility. Difficulties in selling real estate at prices we find acceptable in a timely manner may limit our ability to quickly change or reduce the apartment communities in our portfolio in response to changes in economic, regulatory, or other conditions. Federal tax laws may also limit our ability to sell properties when desired. See "Risks related to our REIT or tax status or reliance on various tax regulations" section for more information on federal tax law risks. In addition, the capitalization rates/disposition yields at which apartment communities may be sold could also be higher than historic rates, thereby reducing our potential proceeds from sale.

Increased scrutiny and changing expectations from regulators, investors, associates, residents and others regarding our environmental, social and governance practices and reporting, including those related to workplace inclusion and diversity (collectively, "Corporate Responsibility" or "CR"), could impact our business practices, cause us to incur additional costs and expose us to new risks. Corporate Responsibility practices and ratings are important to some investors and other stakeholders who may have differing and conflicting views as to their preferred approach to CR matters. Expectations regarding CR may impact our business practices and the price of our securities. Changing practices have in the past and may in the future include expanded mandatory and voluntary reporting, diligence, and disclosure on topics such as climate change, human capital, inclusion and diversity, labor, and risk oversight, and these could expand the nature, scope, and complexity of matters that we are required to control, assess and report on, which may prove difficult, expensive and time consuming. In addition, the adoption of increased government regulations and changes in investor preference related to CR matters may result in changes to our business practices, including increasing expenses or capital expenditures. We have communicated certain initiatives regarding CR matters and we may in the future communicate revised or additional initiatives. If our initiatives are unsuccessful or we fail to satisfy the expectations of investors, residents, employees and other stakeholders, our reputation could be adversely affected. In recent years, corporate initiatives relating to environmental, social and governance matters, including workplace inclusion and diversity, have attracted negative commentary and regulatory attention in the broader business sector. Legislation, regulatory initiatives, litigation, legal opinions, federal executive orders and increased scrutiny related to CR matters could expose the Company to additional compliance obligations, costs, and potential liabilities.

Risks related to operations of our communities

Laws, regulations and orders imposing rent control or rent stabilization, or limiting our rights as a landlord, could adversely affect our operations and revenue. A number of states and municipalities have implemented or are seeking to implement rent control or rent stabilization laws and regulations or take other actions that could limit or delay our ability to raise rents, use algorithmic pricing tools, charge non-rent fees, screen and evict tenants for non-payment of rent or other lease violations. For example, the State of California has statewide rent control for communities older than fifteen years, limiting rent increases to the lesser of 10% or 5% plus local CPI, and the State of New York has rules for rent-controlled and rent-stabilized units that limit the way rent increases are calculated for renewal leases, basing increases solely on rent actually paid and eliminating the ability to increase the renewal rent to a higher "registered rent." Furthermore, in California the Governor has the ability to enact local or statewide states of emergency which limit our ability to increase new and renewal rents more than 10% over the rent in place on the date such state of emergency was declared, which has impacted some of our California communities. We have seen an increase in state and local governments in our markets implementing, considering or being urged by various constituencies to consider regulations of the types described above. Additionally, various federal agencies have engaged in efforts aimed at increasing fairness in the rental market. Current and future enactments of rent control or rent stabilization laws or other laws regulating rental housing may limit our ability to charge market rents, increase rents, use algorithmic pricing tools, charge non-rent fees, screen and evict tenants or recover increases in our operating expenses and could make it more difficult for us to dispose of properties in certain circumstances. Expenses associated with our investment in these communities, such as debt service, real estate taxes, insurance and maintenance costs, are generally not reduced when circumstances cause a reduction in rental income from the community.

We face risks related to multifamily rental antitrust, regulatory scrutiny and new litigation. Lawsuits, government investigations and proposed legislation relating to antitrust matters in the multifamily rental market are ongoing and may impact the Company, whether or not we are found directly liable for an antitrust violation. For example, a purported class action has been brought by private litigants against RealPage, Inc., a provider of revenue management systems, and numerous multifamily rental companies; while we were originally named as a defendant, the Company was voluntarily dismissed without prejudice from this case after explaining to plaintiffs’ counsel why the Company believed that these cases were without merit as they pertained to the Company. Subsequently, on November 1, 2023, the District of Columbia filed a lawsuit in the Superior Court of the District of Columbia against RealPage, Inc. and 14 owners and/or operators of multifamily housing in the District of Columbia, including the Company, alleging that the defendants violated the District of Columbia Antitrust Act by unlawfully agreeing to use RealPage, Inc. revenue management systems and sharing sensitive data (the “D.C. Antitrust Litigation”). While we were initially dismissed from this case, the court later granted the District of Columbia leave to amend its original complaint, and the Company has filed a new motion to dismiss which has not been ruled on as of the date of this filing. Further, on January 15, 2025, the Office of the Attorney General of the State of Maryland filed a suit similar to the D.C. Antitrust Litigation in which a number of owners and/or operators of multifamily properties in the State of Maryland, including the Company, have been named (the “Maryland Antitrust Litigation”). While the Company intends to vigorously defend against the D.C. Antitrust Litigation and the Maryland Antitrust Litigation, given the early stage of the lawsuits, the Company is unable to predict the outcome or estimate the amount of loss, if any, that may result from the lawsuits. The Company is also aware that other governmental investigations and lawsuits regarding antitrust matters in the multifamily industry are ongoing, including an antitrust lawsuit brought by the U.S. Department of Justice, along with the attorneys general of ten states, against other multifamily rental providers to which the Company is not a party. Jurisdictions other than the District of Columbia and Maryland, or additional federal agencies, may also bring suits against multifamily rental providers. Regardless of whether the Company remains named in the D.C. Antitrust Litigation, the Maryland Antitrust Litigation or any other lawsuits or becomes the focus of any governmental investigation, the Company may incur substantial costs related to these lawsuits or investigations, whether as a defendant or as a third-party witness. As well, settlements by RealPage, Inc. or other defendants in such cases could impact the multifamily industry in ways that have an adverse effect on the Company. In addition, state and federal legislation has been introduced (and in San Francisco adopted) to regulate the use by multifamily apartment rental companies of third party algorithmic revenue management systems, and if legislation of this type passes, the impact on the Company is difficult to predict. Lawsuits, government investigations and new legislation related to antitrust matters may, among other things, be costly to comply with, result in negative publicity, require significant management time and attention and subject us to remedies or burdensome requirements that adversely affect our business.

Noncompliance with applicable laws in the building and operation of our communities could adversely affect our operations or expose us to liability. We must develop, construct and operate our communities in compliance with federal, state and local laws and regulations, some of which may conflict with one another or be subject to limited judicial or regulatory interpretations. These laws and regulations may include zoning laws, building codes, landlord/tenant laws and other laws generally applicable to business operations. Noncompliance with laws could expose us to liability. Lower revenue growth or significant unanticipated expenditures may result from our need to comply with changes in (i) laws imposing remediation requirements or

14

Table of Contents

other conditions, or (ii) other governmental rules and regulations or enforcement policies affecting the development, use and operation of our communities, including changes to building codes and fire and life-safety codes.

Short-term leases expose us to the effects of declining market rents. Most of our apartment leases are for a term of one year or less. Because these leases generally permit the residents to leave at the end of the lease term without penalty, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.

Competition could limit our ability to lease apartment homes or increase or maintain rents. Our apartment communities compete with other apartment operators as well as rental housing alternatives, such as single-family homes for rent and short term furnished offerings such as those available from extended stay hotels or through online listing services. In addition, our residents and prospective residents also consider, as an alternative to renting, the purchase of a new or existing condominium or single-family home. Competitive residential housing could adversely affect our ability to lease apartment homes and to increase or maintain rental rates.

Unfavorable changes in market and economic conditions could adversely affect occupancy, rental rates, operating expenses, and the overall market value of our real estate assets. Local conditions in our regions significantly affect occupancy, rental rates and the operating performance of our communities, and may be adversely affected by the following risks:

•corporate restructurings and/or layoffs, and industry slowdowns;

•an oversupply of, or a reduced demand for, apartment homes;

•a decline in household formation or employment or lack of employment growth;

•the inability or unwillingness of residents to pay rent increases; and

•economic conditions that could cause an increase in our operating expenses, such as increases in property taxes, utilities, compensation of on-site associates and routine maintenance.

Risks related to the impact of a pandemic, epidemic or other health crisis on multifamily rental housing. The national and global impacts of a health crisis, such as the COVID-19 pandemic, may present material uncertainty and risk with respect to our financial condition, results of operations and cash flows. State, local, and federal entities may impose restrictions, for varying times and to varying degrees (as experienced during the COVID-19 pandemic), on our ability to enforce residents’ contractual lease obligations, and this may affect our ability to enforce all of our remedies (such as pursuing collections, imposing late fees and seeking evictions) for the failure to pay rent and may result in foregone revenue. Our properties could also incur significant costs or losses related to shelter-in-place or stay-at-home orders, quarantines, infection, clean-up costs or other related factors, which may cause residents to move to locations other than our markets. Moreover, many of the risk factors set forth in this Form 10-K could be interpreted as heightened risks due to the impact of a pandemic, epidemic or other health crisis.

Further, emergency orders such as shutting down non-essential businesses, may disrupt our development and construction activity which may increase our construction costs and we may not achieve, on the schedule we originally planned, the cash flows that we expect when we begin leasing a completed property. We may also delay the start of construction of additional development communities which, if constructed and leased as originally planned, would have been a source of future additional cash flow.

The same factors as described immediately above may also impact our workforce. A disruption in the normal operations of our workforce, including impacts of illness among a substantial portion of our workforce, could also adversely affect our operations.

Risks related to commercial leasing operations. Although we are primarily in the multifamily rental business, we also own and lease ancillary commercial space. Gross rental revenue provided by leased commercial space in our portfolio represented 1.4% of our total revenue in 2024. The long term nature of our commercial leases and characteristics of many of our tenants (small, local businesses) may subject us to certain risks. We may not be able to lease new space for rents that are consistent with our projections or at market rates. Also, when leases for our existing commercial space expire, 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 current lease terms. Our properties compete with other properties with commercial space. If our commercial tenants experience financial distress or bankruptcy, they 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.

Inflation and related volatility in the economy could negatively impact our residents and our results of operations. Although it has declined from its 2022 peak, inflation has remained elevated in 2023 and 2024 compared to pre-pandemic years, and may continue at the present level or increase. Inflation and its related impacts, including increased prices for services and goods and higher interest rates and wages, and any policy interventions by the U.S. government, could negatively impact our residents’

15

Table of Contents

ability to pay rents or our results of operations. Most of our apartment leases are for a term of one year or less, which we believe mitigates our exposure to inflation by permitting us to set rents commensurate with inflation (subject to rent regulations to the extent they apply and assuming our current or prospective residents will accept and can pay commensurate increased rents, of which there can be no assurance). However, inflation could outpace any increases in rent and adversely affect us. In addition, property taxes can be impacted by inflationary changes because taxes in some jurisdictions are regularly reassessed based on changes in the fair value of our properties. We may not be able to mitigate the effects of inflation and related impacts, and the duration and extent of any prolonged periods of inflation, and any related adverse effects on our results of operations and financial condition, are unknown at this time. Inflation may also cause increased volatility in financial markets, which could affect our ability to access the capital markets or impact the cost or timing at which we are able to do so.

Inflation, either caused by tariffs recently imposed or threatened by the new presidential administration or due to other causes, may also increase the costs to complete our development projects, including costs of materials, labor and services from third-party contractors and suppliers. Higher construction costs could adversely impact our investments in real estate assets and our expected yields on development projects.

Risks related to our REIT or tax status or reliance on various tax regulations

Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to stockholders. If we fail to qualify as a REIT for federal income tax purposes, we will be subject to regular federal corporate income tax on our taxable income. In addition, unless we are entitled to relief under applicable statutory provisions, we would be ineligible to make an election for treatment as a REIT for the four taxable years following the year we lose our qualification. The additional tax liability resulting from the failure to qualify as a REIT would significantly reduce or eliminate the amount of funds available for distribution to our stockholders. Furthermore, we would no longer be required to make distributions to our stockholders. Thus, our failure to qualify as a REIT could also impair our ability to expand our business and raise capital and would adversely affect the value of our common stock.

We believe that we are organized and qualified as a REIT, and we intend to operate in a manner that will allow us to continue to qualify as a REIT. However, we cannot assure you that we are qualified as a REIT, or that we will remain qualified in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are only limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control. Our qualification as a REIT depends on our satisfaction of certain asset, income, organizational, distribution, shareholder ownership and other requirements on a continuing basis. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of such qualification. Additionally, our expanding range of investments (such as investments in mezzanine loans, preferred equity, and technology and environmentally focused venture funds and companies) may add additional REIT compliance challenges, some of which may involve determinations or circumstances that may be beyond our control.

Even if we qualify as a REIT, we will be subject to certain federal, state and local taxes on our income and property and on taxable income that we do not distribute to our stockholders. In addition, we hold certain assets and engage in certain activities through our TRSs that a REIT could not engage in directly. We also use TRSs to hold certain assets that we believe would be subject to the 100% prohibited transaction tax if sold at a gain outside of a TRS or to engage in activities that generate non-qualifying REIT income. Our TRSs are subject to federal income tax as regular corporations.

Legislative or other actions affecting REITs could have a negative effect on us or our stockholders. The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service ("IRS") and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive legislation, could adversely affect us or our stockholders. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect our ability to qualify as a REIT, the federal income tax consequences of such qualification, or the federal income tax consequences of an investment in our Company. Also, the law relating to the tax treatment of other entities, or an investment in other entities, could change, making an investment in such other entities more attractive relative to an investment in a REIT.

Our ownership of TRSs is subject to certain restrictions, and we will be required to pay a 100% penalty tax on certain income or deductions if transactions with our TRSs are not conducted on arm’s-length terms. We have established several TRSs. The TRSs must pay federal income tax on their taxable income as regular corporations. While we will attempt to ensure that our dealings with our TRSs do not adversely affect our REIT qualification, we cannot provide assurances that it will successfully achieve that result. Furthermore, we may be subject to a 100% penalty tax, to the extent dealings between us and

16

Table of Contents

our TRSs are not deemed to be arm’s-length in nature. We intend that our dealings with our TRSs will be on an arm’s-length basis. No assurances can be given, however, that the IRS will not assert a contrary position.

Failure of one or more of our subsidiaries to qualify as a REIT could adversely affect our ability to qualify as a REIT. We have owned and may in the future own interests in subsidiaries that have elected (or will elect) to be taxed as REITs under the Code. These subsidiary REITs were or will be subject to the REIT qualification requirements and other limitations that are applicable to us. If any of our subsidiary REITs were to fail to qualify as a REIT, then (i) the subsidiary REIT would become subject to federal income tax, (ii) our ownership of shares in such subsidiary REIT would cease to be a qualifying asset for purposes of the asset tests applicable to REITs, and (iii) it is possible that we could also fail to qualify as a REIT.

The tax imposed on REITs engaging in "prohibited transactions" may limit our ability to engage in transactions which would be treated as sales for federal income tax purposes. We may transfer or otherwise dispose of some of our properties. Under the Code, unless certain exceptions apply, any gain resulting from transfers of properties that we hold as inventory or primarily for sale to customers in the ordinary course of business could be treated as income from a prohibited transaction subject to a 100% penalty tax from the gain on the sale of the property, which could potentially adversely impact our status as a REIT unless we own the property through a TRS. Since we acquire properties for investment purposes, we do not believe that our occasional transfers or disposals of property should be treated as prohibited transactions. However, whether property is held for investment purposes depends on the facts and circumstances surrounding the particular transaction. The IRS may contend that certain of our transfers or disposals of properties are prohibited transactions. If the IRS were to argue successfully that a transfer or disposition of property was a prohibited transaction, then we would be required to pay a 100% penalty tax on any gain allocable to it from the prohibited transaction, and our ability to retain proceeds from real property sales may be jeopardized.

We may face risks in connection with Section 1031 exchanges. We may dispose of real properties in transactions intended to qualify as "like-kind exchanges" under Section 1031 of the Code. If a transaction intended to qualify as a Section 1031 exchange is later determined to be taxable, we may face adverse consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of real properties on a tax-deferred basis.

We may choose to pay dividends in our own stock, in which case, stockholders may be required to pay tax in excess of the cash they receive. We may distribute taxable dividends that are payable in part in our stock. Taxable stockholders receiving such dividends will be required to include the full amount of the dividend as income to the extent of our current and accumulated earnings and profits for federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of the cash dividend received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, the trading price of our stock would experience downward pressure if a significant number of our stockholders sell shares of our stock in order to pay taxes owed on dividends.

Risks that may not be insured in full or in part

We are exposed to risks that are either uninsurable, not economically insurable or in excess of our insurance coverage, including risks discussed below. Insurance coverage for various risks can be costly and in limited supply. 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 our view, economically impractical. Incidents that directly or indirectly damage our communities, both physically and financially, or cause losses that exceed our insurance coverage (including amounts payable by our captive insurance company) could have a material adverse effect on our business, financial condition and results of operations including increased maintenance, repair, and delays in construction. In addition, we would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community which could have a material adverse effect on our business and our financial condition and results of operations. The following risks are uninsurable or insurance coverage is limited due to premium rates (See Item 2. "Properties—Insurance and Risk of Uninsured Losses"):

•Earthquake risk. As further described in Item 2. "Properties—Insurance and Risk of Uninsured Losses," many of our West Coast communities are located in the general vicinity of active earthquake faults. Insurance coverage for earthquakes can be costly and in limited supply.

•Climate, severe or inclement weather or natural disaster risk. Many of our markets, particularly those located in coastal cities, are exposed to risks associated with inclement or severe weather including those arising from climate change such as hurricanes, severe winter storms and coastal flooding. Many of our properties are also located in areas,

17

Table of Contents

such as Southern California or Texas, that are exposed to risks of drought, wildfire or other natural disasters, including those arising from climate change. For example, in Southern California, a series of wildfires affected the Los Angeles metropolitan area and San Diego in January 2025, forcing over 200,000 people to evacuate and resulting in the destruction or damage of thousands of homes and structures. Additionally, the 2024 hurricane season was particularly severe and saw landfall of two major hurricanes in Florida and significant damage from flooding in North Carolina. Although none of these events caused material damage to our properties, similar disasters could occur in the future.

•Terrorism and other risk. We have significant investments in metropolitan markets such as Metro New York/New Jersey and Washington, D.C., which have in the past been or may in the future be the target of actual or threatened terrorist attacks. We carry commercial general liability insurance, property insurance and terrorism insurance with respect to our communities on terms and in amounts we consider commercially reasonable. There are, however, certain types of losses (such as from acts of war) we do not insure, in full or in part, because they are either uninsurable or we believe the cost of insurance is economically impractical.

We may incur costs related to climate change. We may experience physical climate change impacts including extreme weather, sea level rise, the effects of declines in available water supplies and changes in precipitation, temperature and wildfire exposure, all of which may result in damage to, disruption of services at, and/or a decrease in demand for properties located in areas affected by these conditions. Should the impact of these conditions be material or occur for lengthy periods of time, our financial condition or results of operations may be adversely affected, and it may negatively impact the types and pricing of insurance we are able to procure.

In addition, we may experience transition risks associated with climate change. The implementation of new or changes in existing federal, state and local regulations based on concerns about climate change could result in increased capital expenditures or operating expenses on our existing properties (for example, required retrofitting of existing systems or increased utility costs) and our new development properties (for example, to improve energy efficiency, reduce greenhouse gas emissions and/or improve resistance to inclement weather) without a corresponding increase in revenue, resulting in adverse impacts to our results of operations. Further, laws and regulations at the federal, state and local level requiring climate-related disclosures, including the rules promulgated by the SEC and the legislation recently enacted in the state of California, may increase compliance and data collection costs if, and when, such laws and regulations become effective.

We may incur costs due to environmental contamination or non-compliance. Under various public health laws and regulations, we may be required, regardless of knowledge or responsibility, to investigate and remediate the presence or effects of hazardous or toxic substances such as asbestos, lead paint, chemical vapors from soils or groundwater, petroleum product releases, and natural substances such as methane and radon gas. We may be held liable under these laws or common law to a governmental entity or to third parties for property, personal injury or natural resources damages and for investigation and remediation costs incurred as a result of the contamination. These damages and costs may be substantial and may exceed any insurance coverage we have for such events. The presence of these substances, or the failure to properly remediate or contain the contamination, may adversely affect our ability to borrow against, develop, sell or rent the affected property. In addition, some environmental laws create or allow a government agency to impose a lien on the contaminated site in favor of the government for damages and costs it incurs as a result of the contamination.

The development, construction and operation of our communities are subject to environmental, health and safety regulations and permitting under various federal, state and local laws, regulations and ordinances, which regulate matters including wetlands protection, storm water runoff and wastewater discharge. These laws and regulations may impose restrictions on how our communities may be developed, and noncompliance with these laws and regulations may subject us to fines and penalties and may subject us to liability in connection with personal injury.

Certain laws and regulations govern the removal, encapsulation or disturbance of asbestos containing materials ("ACMs") when such materials are in poor condition or in the event of renovation or demolition of a building. These laws and the common law may impose liability for release of ACMs and may allow third parties to seek recovery from owners or operators of real properties for personal injury associated with exposure to ACMs. We are not aware that any ACMs were used in the construction of the communities we developed. ACMs were, however, used in the construction of a number of the communities that we have acquired. Although we implement an operations and maintenance program at each of the communities at which ACMs are detected, we may fail to adequately observe such program or a disturbance of ACMs may occur nevertheless, exposing us to liability. We are aware that some of our communities have lead paint and have implemented an operations and maintenance program at each of those communities.

18

Table of Contents

All of our stabilized operating communities, and all of the communities that we are currently developing, have been subjected to at least a Phase I or similar environmental assessment, which generally does not involve invasive techniques such as soil or groundwater sampling. These assessments, together with subsurface assessments conducted on some properties, have not revealed, and we are not otherwise aware of, any environmental conditions that we believe would have a material adverse effect on our business, assets, financial condition or results of operations. In connection with our ownership, operation and development of communities, we may undertake substantial remedial action in response to the presence of subsurface or other contaminants, including contaminants in soil, groundwater and soil vapor beneath or affecting our buildings. In some cases, an indemnity exists upon which we may be able to rely if environmental liability arises from the contamination or remediation costs exceed estimates. There can be no assurance, however, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that environmental liability arises.

Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Certain molds may lead to adverse health effects, including allergic or other reactions. We cannot provide assurance that mold or excessive moisture will be detected and remediated in a timely manner. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities that may exceed any applicable insurance coverage.

Additionally, we have occasionally been involved in developing, managing, leasing and operating various properties for third parties. Consequently, we may be considered to have been an operator of such properties and, therefore, potentially liable for removal or remediation costs or other potential costs which relate to the release or presence of hazardous or toxic substances or petroleum products at such properties.

We cannot assure you that:

•the environmental assessments described above have identified all potential environmental liabilities;

•no prior owner created any material environmental condition not known to us or the consultants who prepared the assessments;

•no environmental liabilities have developed since the environmental assessments were prepared;

•the condition of land or operations in the vicinity of our communities, such as the presence of underground storage tanks, will not affect the environmental condition of our communities;

•future uses or conditions, including, without limitation, changes in applicable environmental laws and regulations, will not result in the imposition of environmental liability; and

•no environmental liabilities will arise at communities that we have sold for which we may have liability.

General Risk Factors

The ability of our stockholders to control our policies and effect a change of control of our company is limited by certain provisions of our charter and bylaws and by Maryland law. There are provisions in our charter and bylaws that may discourage a third party from making a proposal to acquire us. These provisions include the following:

Our charter authorizes our Board of Directors to issue up to 50,000,000 shares of preferred stock without stockholder approval and to establish the preferences and rights, including voting rights, of any series of preferred stock issued. This could allow the Board to issue one or more classes or series of preferred stock that could discourage or delay a tender offer or a change in control.

To maintain our qualification as a REIT for federal income tax purposes, not more than 50% in value of our outstanding stock may be owned, directly or indirectly, by or for five or fewer individuals at any time during the last half of any taxable year. To maintain this qualification, and/or to address other concerns about concentrations of ownership of our stock, our charter generally prohibits ownership (directly, indirectly by virtue of the attribution provisions of the Code, or beneficially as defined in Section 13 of the Exchange Act) by any single stockholder of more than 9.8% of the issued and outstanding shares of any class or series of our stock. In general, under our charter, pension plans and mutual funds may directly and beneficially own up to 15% of the outstanding shares of any class or series of stock. Under our charter, our Board of Directors may in its sole discretion waive or modify the ownership limit for one or more persons, but it is not required to do so even if such waiver would not affect our qualification as a REIT. These ownership limits may prevent or delay a change in control and, as a result, could adversely affect our stockholders' ability to realize a premium for their shares of common stock.

As a Maryland corporation, we are subject to the provisions of the Maryland General Corporation Law which restricts some business combinations and requires compliance with statutory procedures before some mergers and acquisitions may occur,

19

Table of Contents

which may delay or prevent offers to acquire us even if they are in our stockholders' best interests. In addition, other provisions of the Maryland General Corporation Law permit the Board of Directors to make elections and to take actions without stockholder approval (such as classifying our Board such that the entire Board is not up for re-election annually) that, if made or taken, could have the effect of discouraging or delaying a change in control.

Litigation could adversely affect our business. We are and may in the future become involved in legal proceedings, claims, actions, inquiries and/or investigations in connection with our operations, which may result in defense costs, settlements, fines and/or judgments against us, some of which are not, or cannot be, covered by insurance, including risks related to the multifamily rental antitrust litigation discussed elsewhere in this Form 10-K. Legal proceedings and other claims, if decided adversely to or settled by us, and not covered by insurance, could result in liability material to our financial condition, results of operations or cash flows. Likewise, regardless of outcome, legal proceedings and other claims may result in substantial costs and expenses, affect the availability or cost of some of our insurance coverage and significantly divert the attention of our management. With respect to any legal proceeding or other claim, there can be no assurance that we will be able to prevail, or achieve a favorable settlement or outcome, or that our insurance and/or any contractual indemnities will be enough to cover all of our defense costs or any resulting liabilities.

Changes in U.S. accounting standards may materially and adversely affect the reporting of our operations. We follow accounting principles generally accepted in the United States ("GAAP"). GAAP is established by the Financial Accounting Standards Board ("FASB"), an independent body whose standards are recognized by the SEC as authoritative for publicly held companies. The FASB and the SEC create and interpret accounting standards and may change the interpretation and application of these standards that govern the preparation of our financial statements. These changes could have a material impact on our reported consolidated results of operations and financial position.

We rely on information technology in our operations, and any breach, interruption or security failure of that technology, or any non-compliance with applicable laws with respect to the use of that technology, could have a negative impact on our business, results of operations, financial condition and/or reputation. We rely on information technology, including the internet, to process, transmit and store electronic information, and to manage or support a variety of business processes, including financial transactions, personally identifiable information ("PII"), and tenant and lease data. Our business requires us and some of our vendors to use and store PII and other confidential and sensitive information of our residents and employees. Privacy and information security laws and regulations for PII continue to evolve and may be inconsistent from one jurisdiction to another. Compliance with all such laws and regulations may increase our operating costs and adversely impact our ability to market our properties and services.

Information security risks have generally increased in recent years due to the rise in new technologies, such as ransomware and generative artificial intelligence, and the increased sophistication and activities of perpetrators of cyber-attacks, including as a result of the intensification of state-sponsored cybersecurity attacks during periods of geopolitical conflict. Cyber-attacks can include third parties gaining access to data using stolen or inferred credentials, computer malware, viruses, spamming, phishing attacks, ransomware, and other deliberate attacks and attempts to gain unauthorized access to our or our vendors’ data or information technology systems. Although our and our vendors' information technology systems are essential to the operation of our business and our ability to perform day-to-day operations, even the most well-protected information, networks, systems and facilities remain potentially vulnerable because the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases are designed not to be detected and, in fact, may not be detected. Accordingly, we may be unable to implement adequate security barriers or other preventative measures, and thus it is impossible for us to entirely mitigate this risk. These threats, in turn, may lead to increased costs to protect our information systems, detect and respond to threats, and recover from cyber incidents. Our insurance program may not be adequate to cover all losses relating to such events.

There can be no assurance that we will be able to prevent unauthorized access to PII or to our network or business systems in general. Any failure in or breach of our operational or information security systems, or those of our vendors, as a result of cyber-attacks or other security incidents, could materially adversely impact our operations and financial position, including disruption of our operations caused by an inability to access network systems, disclosure or misuse of confidential or proprietary information (including PII of our residents and/or associates), damage to our reputation, and/or potentially significant legal and/or financial liabilities and penalties.

Various laws and regulations and interpretations thereof, as well as agreements with payment processors, require, or may require, us to comply with rules related to our business and our websites used by residents and prospective residents, including requirements related to accessibility of our websites to persons with disabilities and our handling and use of data, including personal data, that we collect. We could face liabilities for failure to comply with these requirements. Privacy laws and

20

Table of Contents

regulations, such as the California Consumer Privacy Act as amended by the California Privacy Rights Act and the Texas Data Privacy and Security Act, related regulations and other U.S. state privacy laws, are evolving and may be subject to differing interpretations. We could incur costs to comply with stricter and more complex data privacy, data collection and information security laws and standards.

Any material weaknesses identified in our internal control over financial reporting could have an impact on our Company. Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate and report on our internal control over financial reporting. One or more material weaknesses in our internal control over financial reporting could result in misstatements of our results of operations and related restatements, a decline in the price/value of our securities, or otherwise materially adversely affect our business, reputation, results of operations, financial condition or liquidity.

Our success depends on key personnel whose continued service is not guaranteed. Our success depends in part on our ability to attract and retain the services of executive officers and other personnel. There is substantial competition for qualified personnel in the real estate industry, and the loss of our key personnel could adversely affect us.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

We have implemented and maintain a risk management framework designed to identify, assess, and mitigate risks from cybersecurity threats. We assess our cybersecurity program ("CSP"), as part of our enterprise risk management program, against the National Institute of Standards and Technology’s Cybersecurity Framework ("NIST CSF") and also use as a model the Center for Internet Security ("CIS") control framework’s Implementation Group 2 ("IG2"). We perform annual assessments against NIST CSF benchmarks and focus on continuous improvement over those criteria. We use a list of factors based on business risk tolerance and external compliance requirements to determine if a business asset, data, system, process, or service provider should be included within the scope of the CSP.Prior to contracting with an outside vendor that hosts our data, such as Company information, or PII of our associates or residents, or that integrates with our systems, our policy is to conduct a cybersecurity risk assessment, which includes, as appropriate, a due diligence questionnaire completed by the vendor, a System and Organization Controls 1 ("SOC1") report from major vendors and a review of the vendor’s scope of access to our IT systems and data.

We utilize third-party service providers to enhance our CSP, including engaging them annually to assess our CSP against the NIST CSF. We use one or more third-party managed security solution providers, who provide us with threat intelligence information and managed threat detection and response capabilities. We have also engaged a third party to assist with associate cybersecurity training. Additionally, we have engaged outside breach response legal counsel to assist the Company with cybersecurity counseling and incident response.

Although we have not experienced any material cybersecurity incidents, a future incident could materially affect us. We rely on information technology to process, transmit and store electronic information, and to manage or support a variety of business processes, including financial transactions, PII, and resident and lease data. Our business requires us and some of our vendors to use and store PII and other confidential and sensitive information of our residents and associates. Any failure in or breach of our operational or information security systems or those of our vendors as a result of cyber-attacks or other security incidents could materially adversely impact our operations and financial position, including disruption of our operations caused by an inability to access network systems, disclosure or misuse of confidential or proprietary information (including PII of our residents and/or associates), damage to our reputation, and/or potentially significant legal and/or financial liabilities and penalties.

You should carefully review Part I, Item 1A. "Risk Factors" of this Form 10-K for a discussion of the risks to the Company related to cybersecurity.

Governance

Our cybersecurity team is led by our Senior Director of Cybersecurity, who has over 15 years of experience with IT and cybersecurity. The cybersecurity team reports to our Senior Vice President-Information Technology. The Senior Director of Cybersecurity and the Senior Vice President-Information Technology are part of, and work with, a management Cybersecurity Steering Committee ("CSC"), which meets regularly. The CSC works to ensure strategic alignment of the CSP with our

21

Table of Contents

business objectives and priorities. The CSC is chaired by the Senior Director of Cybersecurity and is composed of our Chief Financial Officer, Chief Operating Officer, General Counsel and senior members of our finance, legal, IT, risk management and internal audit teams. The Company has designated an incident response team and defined criteria to guide responses to cybersecurity incidents.

The Audit Committee of our Board of Directors provides Board-level oversight of risks from cybersecurity threats. In addition to providing periodic reports, at least annually the Senior Director of Cybersecurity and the Senior Vice President-Information Technology meet with the Audit Committee regarding cybersecurity risks and assessments and related Company policies and initiatives. The Audit Committee and management have adopted a policy that categorizes cybersecurity incidents and sets out incident escalation procedures to the full Board of Directors.

ITEM 2. PROPERTIES

Our real estate investments consist primarily of current operating apartment communities ("Current Communities"), consolidated and unconsolidated communities in various stages of development ("Development" communities and "Unconsolidated Development" communities) and Development Rights (as defined below). Our Current Communities are further classified as Same Store communities, Other Stabilized communities, Redevelopment communities and Unconsolidated communities. While we generally establish the classification of communities on an annual basis, we update the classification of communities during the calendar year to the extent that our plans with regard to the disposition or redevelopment of a community change, or if something occurs that materially impacts the operations of a community such as a casualty loss. The following is a description of each category:

Current Communities are categorized as Same Store, Other Stabilized, Redevelopment or Unconsolidated according to the following attributes:

•Same Store is composed of consolidated communities where a comparison of operating results from the prior year to the current year is meaningful as these communities were owned and had stabilized occupancy as of the beginning of the prior year. For the year ended December 31, 2024, Same Store communities are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2023, did not conduct substantial redevelopment activities and are not held for sale as of December 31, 2024. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 90% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

•Other Stabilized is composed of completed consolidated communities that we own and that are not Same Store but which have stabilized occupancy, as defined above, as of January 1, 2024, or which were acquired subsequent to January 1, 2023. Other Stabilized excludes communities that are conducting or conducted substantial redevelopment activities within the current year, as defined below.

•Redevelopment is composed of consolidated communities where substantial redevelopment occurred or is in progress. Redevelopment is considered substantial when (i) capital invested is expected to exceed the lesser of $5,000,000 or 10% of the community's pre-redevelopment basis and (ii) physical occupancy is below or is expected to be below 90% during, or as a result of, the redevelopment activity.

•Unconsolidated is composed of communities that we have an indirect ownership interest in through our investment interest in an unconsolidated joint venture.

Development is composed of consolidated communities that are either currently under construction, were under construction and were completed during the current year or where construction has been complete for less than one year and that do not have stabilized occupancy. These communities may be partially or fully complete and operating.

Development Rights are development opportunities in the early phase of the development process where we either have an option to acquire land or enter into a leasehold interest, where we are the buyer under a long-term conditional contract to purchase land, where we control the land through a ground lease or own land to develop a new community, or where we are the designated developer in a public-private partnership. We capitalize related pre-development costs incurred in pursuit of new developments for which we currently believe future development is probable.

We currently lease our corporate headquarters located in Arlington, Virginia, as well as our other regional and administrative offices, under operating leases.

(1) Communities were removed from our Same Store portfolio if we believed that planned activity for the upcoming year would result in that community's expected operations not being comparable to the prior year, including (i) when we intended to undertake a significant capital renovation, such that the community was classified as a Redevelopment community; (ii) when we intended to dispose of a community; or (iii) when a significant casualty loss occurred.

Current Communities

Our Current Communities include garden-style apartment communities consisting of multi-story buildings of stacked flats and/or townhome apartments in landscaped settings, as well as mid and high rise apartment communities consisting of larger elevator-served buildings of four or more stories, frequently with structured parking. As of January 31, 2025, our Current Communities consisted of the following:

Number ofcommunities Number ofapartment homes

As discussed in Item 1. "Business," we operate under four core brands: Avalon, AVA, eaves by Avalon and Kanso. We believe that this branding differentiation allows us to target our product offerings to multiple customer groups and submarkets within our existing geographic footprint.

We also have an extensive and ongoing maintenance program to continually maintain and enhance our communities and apartment homes. The aesthetic appeal of our communities, and a service-oriented property management team that is focused on the specific needs of residents, enhances market appeal. We believe our mission of "Creating a Better Way to Live" helps us achieve higher rental rates and occupancy levels while minimizing resident turnover and operating expenses.

Table of Contents

Our Current Communities are located in the following geographic markets:

We manage and operate substantially all of our Current Communities. During the year ended December 31, 2024, we completed construction of nine communities containing 2,981 apartment homes, acquired six communities containing 1,441 apartment homes and sold eight operating communities containing 1,532 apartment homes.

Of the Current Communities, as of January 31, 2025, we owned (directly or through wholly-owned subsidiaries):

•275 operating communities, including 268 with a full fee simple or absolute ownership interest, and seven that are on land subject to a land lease. The land leases have various expiration dates from July 2046 to May 2123, and three of the land leases are used to support tax advantaged structures that ultimately allow us to purchase the land upon lease expiration. The Company has purchase options for all land leases expiring prior to 2062.

•A membership interest in five limited liability companies. One of the ventures, the NYTA MF Investors LLC, through subsidiaries owns a fee simple interest in three operating communities and a leasehold interest in two additional operating communities. The other four ventures each hold a fee simple interest in an operating community.

In addition to our Current Communities, we also hold, directly or through wholly-owned subsidiaries, a full fee simple ownership interest in our wholly-owned Development Communities.

As part of the Archstone Acquisition in 2013 (as defined in Item 1. "Business" in the Company's Form 10-K filed with the SEC on February 22, 2019), we acquired, and still own, 14 assets that had previously been contributed by third parties on a tax-deferred basis to an Archstone partnership in which the third parties received ownership interests. To protect the tax-deferred nature of the contribution, the third parties are entitled to cash payments if we trigger tax obligations to the third parties by selling, or failing to maintain sufficient levels of secured financing on, the contributed assets. Our tax protection payment obligations with respect to these assets don’t expire until the death of a third party who contributed ownership interests to the Archstone partnership. After review and investigation of Archstone’s tax and accounting records, we estimate that, had we sold or taken other triggering actions in 2024 with respect to all 14 assets, the aggregate amount of the tax protection payments that would have been triggered would have been approximately $43,815,000. At the present time, we do not intend to take actions that would cause us to be required to make tax protection payments with respect to any of these assets.

Development Communities

As of December 31, 2024, we owned or held a direct interest in 17 Development Communities under construction. We expect these Development Communities, when completed, to add a total of 6,004 apartment homes and 59,000 square feet of commercial space to our portfolio for a total capitalized cost, including land acquisition costs, of approximately $2,253,000,000. We cannot assure you that we will meet our schedule for construction completion or that we will meet our budgeted costs, either individually, or in the aggregate. You should carefully review Item 1A. "Risk Factors" for a discussion of the risks associated with development activity and our discussion under Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" (including the factors identified under "Forward-Looking Statements") for further discussion of development activity.

The following table presents a summary of the Development Communities.

Unconsolidated Operating Communities

As of December 31, 2024, we had investments in the following unconsolidated real estate entities accounted for under the equity method of accounting. See Note 5, "Investments," of the Consolidated Financial Statements included elsewhere in this report. For joint ventures holding operating apartment communities as of December 31, 2024, detail of the real estate and associated indebtedness underlying our unconsolidated investments is presented in the following table (dollars in thousands).

(1)We have not guaranteed the debt of these unconsolidated investees with the exception of the construction loan associated with the Arts District Joint Venture. We bear no responsibility for the repayment unless otherwise disclosed.

(2)Borrowing on this community is comprised of two mortgage loans. The interest rate is the weighted average interest rate as of December 31, 2024.

(3)Borrowing on this dual-branded community is comprised of a single mortgage loan. This dual-branded community is subject to a leasehold interest which is not included in the total capitalized cost.

(4)AVA Arts District completed development during the year ended December 31, 2024 and achieved stabilized residential operations. Itcontains 57,000 square feet of commercial space. The venture had drawn $155,968 of the $167,147 maximum borrowing capacity of the construction loan as of December 31, 2024. While we guarantee 30% of the venture's construction loan, any amounts payable under the guarantee are obligations of the venture partners in proportion to their ownership interest.

(5)In addition to leasehold assets, there were net other assets of $38,506 as of December 31, 2024 associated with our unconsolidated real estate investments which are primarily cash and cash equivalents.

We had an equity interest of 28.6% in the Archstone Multifamily Partners AC LP (the "U.S. Fund") and because we achieved a threshold return for the fund, during the year ended December 31, 2023, we recognized income of $1,519,000 for our promoted interest, which is included in income from unconsolidated investments on the accompanying Consolidated Statements of Comprehensive Income. The U.S. Fund sold its final three communities in 2022 and completed its dissolution in 2023.

Development Rights

At December 31, 2024, we had $151,922,000 in acquisition and related capitalized costs for direct interests in seven land parcels we own. In addition, we had $43,675,000 in capitalized costs (including legal fees, design fees and related overhead costs) related to (i) 17 Development Rights for which we control the land parcel, typically through a conditional agreement or option to purchase or lease the land, as well as (ii) costs incurred for four Development Rights that we expect to construct as additional phases of our existing stabilized operating communities on land we own. Collectively, the land held for development and associated costs for deferred development rights relate to 28 Development Rights for which we expect to develop new apartment communities in the future. The Development Rights range from those beginning design and architectural planning to those that have completed site plans and drawings and can begin construction almost immediately. We estimate that the successful completion of all of these communities would ultimately add approximately 8,801 apartment homes to our portfolio. Substantially all of these apartment homes will offer features like those offered by the communities we currently own.

The Development Rights are in different stages of the due diligence and regulatory approval process. The decisions as to which of the Development Rights to invest in, if any, or to continue to pursue once an investment in a Development Right is made, are business judgments that we make after we perform financial, demographic and other analyses. In the event that we do not proceed with a Development Right, we generally would not recover any of the capitalized costs incurred in the pursuit of those communities, unless we were to recover amounts in connection with the sale of land; however, we cannot guarantee a recovery. Pre-development costs incurred in the pursuit of Development Rights, for which future development is not yet considered probable, are expensed as incurred. In addition, if the status of a Development Right changes, making future development no longer probable, any unrecoverable capitalized pre-development costs are charged to expense. During 2024, we incurred a charge of $18,341,000 for expensed transaction, development and other pursuit costs, net of recoveries, which include development pursuits that were not yet probable of future development at the time incurred, or for pursuits that we determined were no longer probable of being developed. The amount for 2024 includes a write-off of $8,947,000 related to one Development Right in Northern California that we determined was no longer probable.

You should carefully review Item 1A. "Risk Factors," for a discussion of the risks associated with Development Rights.

Acquisition & Disposition Activity

We buy and sell assets based on our long-term investment criteria and target portfolio allocation. We also dispose of assets when capital and real estate markets allow us to realize a portion of the value created over our ownership periods, and we generally redeploy the proceeds from those sales to develop, redevelop and acquire communities. Pending such redeployment, we will generally use the proceeds from the sale of these communities to reduce amounts outstanding under our Credit Facility or Commercial Paper Program or retain the cash proceeds on our balance sheet until it is redeployed into acquisition, development or redevelopment activity. At times, we will set aside the proceeds from the sale of communities into a cash escrow account to facilitate a tax-deferred, like-kind exchange transaction. From January 1, 2024 to January 31, 2025, (i) we acquired six wholly-owned communities containing 1,441 apartment homes for an aggregate purchase price of $460,100,000 and (ii) we sold our interest in nine wholly-owned communities, containing 1,634 apartment homes, with an aggregate gross sales price of $791,300,000.

Insurance and Risk of Uninsured Losses

We maintain commercial general liability insurance and property insurance with respect to all of our communities, with insurance policies issued by a combination of third party insurers as well as a wholly-owned captive insurance company. These policies, along with other insurance policies we maintain, have policy specifications, insured and self-insured limits, exclusions and deductibles that we consider commercially reasonable. We utilize a wholly-owned captive insurance company to insure certain types and amounts of risks, which include property damage and resulting business interruption losses, general liability insurance and other construction related liability risks. The captive is utilized to insure other limited levels of risk, which may be in part reinsured by third party insurance. There are, however, certain types of losses (including, but not limited to, losses arising from nuclear liability, pandemic or acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in management’s view, economically impractical. You should carefully review the discussion under Part I, Item 1A. "Risk Factors" of this Form 10-K for a discussion of risks associated with an uninsured property or casualty loss.

Our communities are insured for certain property damage and business interruption losses through a combination of community specific insurance policies and/or a master property insurance program which covers the majority of our communities. This master property program provides a $400,000,000 limit for any single occurrence and annually in the aggregate, subject to certain sub-limits and exclusions. Under the master property program, we are subject to various deductibles per occurrence, as well as additional self-insured retentions. In addition to our potential liability for the various policy self-insured retentions and deductibles, our captive insurance company is directly responsible for 100% of the first $25,000,000 of losses (per occurrence) and an additional $5,000,000 of losses (per occurrence) incurred by the master property insurance policy. Our master property insurance program includes coverage for losses resulting from customary perils, including but not limited to wildfires and windstorms. Limits, deductibles, self-insured retentions and coverages may increase or decrease annually during the insurance renewal process, which occurs on different dates throughout the calendar year.

Many of our West Coast communities are located within the general vicinity of active earthquake faults. Many of our communities are near, and thus susceptible to, the major fault lines in California, including the San Andreas Fault, the Hayward Fault or other geological faults that are known or unknown. We cannot assure you that an earthquake would not cause damage or losses greater than our current insured levels. We procure property damage and resulting business interruption insurance coverage with a loss limit of $175,000,000 for any single occurrence and in the annual aggregate for losses resulting from earthquakes, subject to deductibles and self-insured retentions. However, for any losses resulting from earthquakes at communities located in California or Washington, the loss limit is $200,000,000 for any single occurrence and in the annual aggregate, subject to deductibles and self-insured retentions. A portion of coverage is included in the aforementioned self-insurance limits underwritten through the captive.

Our Southeast Florida communities could be impacted by significant storm events like hurricanes. We include coverage for losses arising from these types of weather events within our master property insurance program. We cannot assure you that a significant storm event would not cause damage or losses greater than our current insured levels.

Our communities and construction sites are insured for third-party liability losses through a combination of community specific insurance policies and/or coverage provided under a master commercial general liability and umbrella/excess insurance program. The master commercial general liability and umbrella/excess insurance policies cover the majority of our communities and construction sites and are subject to certain coverage limitations and exclusions, which we believe are commercially reasonable. After applicable self-insured retentions borne by us, our captive insurance company is directly responsible for the first $2,000,000 of losses (per occurrence) covered by the master general liability insurance policy.

Just as with office buildings, transportation systems and government buildings, apartment communities could become targets of terrorism. Our communities are insured for terrorism related losses through the Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA") program. This coverage extends to most of our casualty exposures (subject to deductibles and insured limits) and certain property insurance policies. We have also purchased private-market insurance for property damage due to terrorism with limits of $600,000,000 per occurrence and in the annual aggregate that includes certain coverages (not covered under TRIPRA) such as domestic-based terrorism. This insurance, often referred to as "non-certified" terrorism insurance, is subject to deductibles, limits and exclusions.

An additional consideration for insurance coverage and potential uninsured losses is mold growth or other environmental contamination. Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities. For further discussion of the risks and our related prevention and remediation activities, please refer to the discussion under Part I, Item 1A. "Risk Factors - We may incur costs due to

32

Table of Contents

environmental contamination or non-compliance" elsewhere in this report. We cannot provide assurance that we will have coverage under our existing policies for property damage or liability to third parties arising as a result of exposure to mold or a claim of exposure to mold at one of our communities.

We also maintain other insurance programs that provide coverage for events including but not limited to employee dishonesty, loss of data, and liability associated with management of certain employee benefit plans. These policies are subject to maximum loss limits and include coverage limitations or exclusions that may preclude us from fully recovering.

The amount or types of insurance we maintain may not be sufficient to cover all losses and we may change our policy limits, coverages, and self-insured retentions or deductibles at any time.

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

Our common stock is traded on the NYSE under the ticker symbol AVB. On January 31, 2025, there were 663 holders of record of an aggregate of 142,254,778 shares of our outstanding common stock. The number of holders does not include individuals or entities who beneficially own shares but whose shares are held of record by a broker or clearing agency, but does include each such broker or clearing agency as one record holder.

At present, we expect to continue our policy of paying regular quarterly cash dividends. However, the form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

In February 2025, we announced that our Board of Directors declared a dividend on our common stock for the first quarter of 2025 of $1.75 per share, a 2.9% increase over the Company's prior quarterly dividend of $1.70 per share. The dividend will be payable on April 15, 2025 to all common stockholders of record as of March 31, 2025.

Executive Overview

2024 Financial Highlights

Net income attributable to common stockholders for the year ended December 31, 2024 was $1,081,994,000, an increase of $153,169,000, or 16.5%, from the prior year. The increase was primarily attributable to increases in NOI from communities over the prior year, increases in real estate sales and related gains, and increases in income from unconsolidated investments.

Same Store NOI attributable to our apartment rental operations, including parking and other ancillary residential revenue ("Residential"), for the year ended December 31, 2024 was $1,828,266,000, an increase of $48,643,000, or 2.7%, over the prior year. The increase was due to an increase in Same Store Residential revenue of $87,854,000, or 3.4%, partially offset by an increase in Same Store Residential property operating expenses of $39,211,000, or 5.0%, over 2023.

During 2024, excluding the equity capital raised through forward sales of our common shares not yet settled, we raised approximately $1,130,366,000 of gross capital through the sale of wholly-owned real estate and the issuance of unsecured notes. We believe that our current capital structure will continue to provide financial flexibility to access capital on attractive terms.

We believe our portfolio management activity through dispositions, development and acquisitions will continue to create long-term value. During 2024, we:

•sold eight wholly-owned communities containing an aggregate of 1,532 apartment homes and 24,000 square feet of commercial space for $726,200,000;

•completed the construction of nine wholly-owned communities containing an aggregate of 2,981 apartment homes for an aggregate total capitalized cost of $1,286,000,000;

•started the construction of nine wholly-owned communities which in the aggregate are expected to contain 2,921 apartment homes when completed, which are expected to be completed for an estimated total capitalized cost of $1,053,000,000; and

•acquired six wholly-owned communities containing an aggregate of 1,441 apartment homes for an aggregate purchase price of $460,100,000.

During 2024, we issued $400,000,000 principal amount of fixed rate unsecured notes and repaid $300,000,000 principal amount of our fixed rate unsecured notes.

We believe that our balance sheet strength, as measured by our current level of indebtedness, our current ability to service interest and other fixed charges, and our current moderate use of financial encumbrances (such as secured financing), provide us with adequate access to liquidity from the capital markets. We expect to be able to meet our reasonably foreseeable liquidity needs, as they arise, through a combination of one or more of the following sources: existing cash on hand; operating cash flows; the settlement of the outstanding equity forwards; borrowings under our Credit Facility and Commercial Paper Program; the issuance of corporate securities (which could include unsecured debt, preferred equity and/or additional common equity after considering the outstanding equity forwards); the sale of apartment communities; secured debt; or through the formation of joint ventures. See the discussion under "Liquidity and Capital Resources."

Communities Overview

As of December 31, 2024, we owned or held a direct or indirect ownership interest in 306 communities containing 93,518 homes in 12 states and the District of Columbia, of which 17 communities were under development. We have an indirect interest in nine of the 306 communities which were owned by entities that were not consolidated for financial reporting purposes. In addition, we held a direct or indirect ownership interest in Development Rights to develop an additional 28 communities that, if developed as expected, will contain an estimated 8,801 apartment homes.

Our real estate investments consist primarily of Current Communities, Development communities, Unconsolidated Development communities and Development Rights. Our Current Communities are further classified as Same Store communities, Other Stabilized communities, Redevelopment communities and Unconsolidated communities.

Same Store communities are consolidated communities that were owned and had stabilized occupancy as of the beginning of the prior year, allowing for a meaningful comparison of operating results between years. Other Stabilized communities are generally all other completed consolidated communities that have stabilized occupancy at the beginning of the current year or were acquired during the year. Redevelopment communities are consolidated communities where substantial redevelopment is in progress or is probable to begin during the current year. Unconsolidated communities are communities in which we have an indirect ownership interest through our investment interest in an unconsolidated joint venture. A more detailed description of our reportable segments and other related operating information can be found in Note 8, "Segment Reporting," of our Consolidated Financial Statements.

Although each of these categories is important to our business, we generally evaluate overall operating, industry and market trends based on the operating results of Same Store communities, for which a detailed discussion can be found in "Results of Operations" as part of our discussion of overall operating results. We evaluate our current and future cash needs and future operating potential based on acquisition, disposition, development, redevelopment and financing activities within Other Stabilized, Redevelopment and Development communities. Discussions related to current and future cash needs and financing activities can be found under “Liquidity and Capital Resources.”

NOI of our current operating communities is one of the financial measures that we use to evaluate the performance of our communities. NOI is affected by the demand and supply dynamics within our markets, our rental rates and occupancy levels and our ability to control operating costs. Our overall financial performance is also impacted by the general availability and cost of capital and the performance of newly developed, redeveloped and acquired apartment communities.

Results of Operations

Our results of operations are driven by our operating platform and are primarily affected by both overall and individual geographic market conditions and apartment fundamentals and are reflected in changes in Same Store NOI; NOI derived from acquisitions, development completions and development under construction and in lease-up; loss of NOI related to disposed communities; and capital market and financing activity. See also Part I, Item 1A, "Risk Factors." Discussion of our operating results for 2023 and comparison to 2022 can be found in Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Form 10-K filed with the SEC on February 23, 2024. A comparison of our operating results for 2024 and 2023 follows (dollars in thousands).

(1) Percent change is not meaningful.

Net income attributable to common stockholders increased $153,169,000, or 16.5%, to $1,081,994,000 in 2024 from 2023, primarily due to increases in (i) NOI from communities, (ii) real estate sales and related gains, and (iii) income from unconsolidated investments in the current year.

NOI. We define NOI as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), property management and other indirect operating expenses, net of corporate income, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, loss on extinguishment of debt, net, general and administrative expense, income from unconsolidated investments, depreciation expense, income tax expense (benefit), casualty and impairment loss, gain on sale of communities, other real estate activity and net operating income from real estate assets sold or held for sale. Management considers NOI to be an important and appropriate supplemental performance measure to net income because it helps both investors and management to understand the core operations of a community or communities prior to the allocation of any corporate-level property management overhead or financing-related costs. NOI reflects the operating performance of a community and allows for an easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or group of assets.

NOI does not represent cash generated from operating activities in accordance with GAAP, and NOI should not be considered an alternative to net income as an indication of our performance. NOI should also not be considered an alternative to net cash flow from operating activities, as determined by GAAP, as a measure of liquidity, nor is NOI indicative of cash available to

The 2.7% increase in our Same Store Residential NOI in 2024 is due to an increase in Residential revenue of $87,854,000, or 3.4%, partially offset by an increase in Residential property operating expenses of $39,211,000, or 5.0%, over 2023.

Increases in inflation can result in an increase in our operating costs both at our communities and at the corporate level. Most of our apartment leases are for a term of one year or less. In an inflationary environment, this may allow us to realize increased rents upon renewal of existing leases or the beginning of new leases. Short-term leases generally reduce our risk from the adverse effect of inflation, although these leases also permit residents to leave at the end of their lease term. In addition, inflation could cause our construction costs and cost of other capitalized expenditures to increase, impacting the expected economic return of, and expected operating results for, current and planned development activity.

Rental and other income increased $146,489,000, or 5.3%, in 2024 compared to the prior year primarily due to the increased revenue from our Same Store communities, discussed below.

Consolidated Communities —The weighted average number of occupied apartment homes for consolidated communities increased to 79,240 apartment homes for 2024, compared to 77,667 homes for 2023. The weighted average monthly revenue per occupied apartment home increased to $3,081 for 2024 compared to $2,955 in 2023.

Same Store Communities — The following table presents the change in Same Store Residential revenue, including the

For the year ended December 31,

_________________________________

(1) Economic Occupancy is defined as gross potential revenue less vacancy loss, as a percentage of gross potential revenue. Gross potential revenue is determined by valuing occupied homes at contract rates and vacant homes at market rents. Vacancy loss is determined by valuing vacant units at market rents. Economic Occupancy considers that apartment homes of different sizes and locations within a community have different economic impacts on a community's gross revenue.

The following table details the increase in Same Store Residential revenue by component for the year ended December 31, 2024, compared to the prior year:

For the year ended

Residential revenue

Lease rates 2.2 %

Economic Occupancy (0.1) %

Other rental revenue 0.9 %

Uncollectible lease revenue (excluding rent relief) 0.5 %

Rent relief (0.1) %

Total Residential revenue 3.4 %

The increase for Same Store Residential revenue for the year ended December 31, 2024, as compared to the prior year was impacted by uncollectible lease revenue, inclusive of amounts received from government rent relief programs. Same Store uncollectible lease revenue decreased for the year ended December 31, 2024 as compared to the prior year by $10,582,000, resulting in a 0.4% increase in Same Store Residential revenue. Uncollectible lease revenue was impacted by a decrease in government rent relief of $3,967,000 for the year ended December 31, 2024 from the prior year. Adjusting to remove the impact of rent relief, uncollectible lease revenue as a percentage of Same Store Residential revenue decreased to 1.8% in the year ended December 31, 2024 from 2.4% in the year ended December 31, 2023.

We use concessions periodically as a means to increase leasing velocity, providing our new and existing residents an upfront incentive to enter into a new lease, or extend an existing lease. During 2024, concessions granted for our Same Store communities increased over the prior year by $562,000 to $17,288,000. We amortize concessions on a straight-line basis over the life of the respective leases (generally one year), reducing the income recognized over the lease term. For the year ended December 31, 2024, amortized concessions increased by $927,000, partially offsetting the increase in revenue as compared to the prior year. The remaining net unamortized balance of Same Store residential concessions as of December 31, 2024 and 2023 was $2,358,000 and $187,000, respectively.

Management, development and other fees decreased $641,000, or 8.3%, in 2024, compared to the prior year, primarily due to reduced third-party development fees, partially offset by an increase in fees for third-party back-office, financial administrative support services in the current year.

Direct property operating expenses, excluding property taxes, increased $36,818,000, or 6.8%, in 2024 compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities as well as increased Residential operating expenses at our Same Store communities as discussed below, partially offset by dispositions.

Same Store Residential direct property operating expenses, excluding property taxes, increased $25,326,000, or 5.0%, in 2024 compared to the prior year, primarily due to the implementation of our bulk internet offering, increased trash removal costs, water and sewer costs, and repairs and maintenance costs.

Property taxes increased $20,817,000, or 6.8%, in 2024 compared to the prior year, primarily due to increases for our Same Store Residential portfolio and the addition of newly developed and acquired apartment communities, partially offset by decreased property taxes from dispositions.

Same Store Residential property taxes increased $13,885,000, or 4.9%, in 2024 compared to the prior year, primarily due to increased assessments across the portfolio, a higher level of successful appeals in the prior year and the expiration of property tax incentive programs primarily at certain of our properties in New York City. The expiration of property tax incentive programs represents $5,364,000 or 39% of the 4.9% increase in property taxes for the year ended December 31, 2024.

Property management and other indirect operating expenses, net of corporate income increased $27,690,000, or 19.5%, in 2024, primarily due to costs related to our shared services model and increased costs related to investments in technology and process related spend for initiatives to improve future efficiency in services for residents and prospects, and increased advocacy costs.

Expensed transaction, development and other pursuit costs, net of recoveries includes costs incurred for write downs and abandonment of Development Rights and development pursuits not yet considered probable for development, as well as costs related to abandoned acquisition and disposition pursuits, offset by any recoveries of costs incurred. In periods of increased acquisition and pursuit activity, periods of economic downturn or when there is limited access to capital, these costs can be volatile and may vary significantly from year to year. In addition, the timing for potential recoveries will not always align with the timing for expensing an abandoned pursuit. Expensed transaction, development and other pursuit costs, net of recoveries, decreased $15,138,000 in 2024 compared to the prior year due to a decrease in write-offs for development rights that we determined are no longer probable. The amount for 2024 includes a write-off of $8,947,000 related to one Development Right in Northern California, and the amount for 2023 includes write-offs of $27,455,000 related to seven Development Rights in Northern and Southern California and the Mid-Atlantic that we determined were no longer probable.

Interest expense, net increased $20,597,000, or 10.0%, in 2024 compared to the prior year. This category includes interest costs adjusted for capitalized interest related to development and redevelopment activity, amortization of premium/discount on debt, deferred hedging gains and losses from qualifying hedges, interest income and any mark-to-market impact from derivatives not in qualifying hedge relationships. The increase in 2024 was primarily due to increases in amounts of unsecured indebtedness and decreases in interest income compared to the prior year due to lower cash amounts invested. The increases in 2024 are also due to decreased capitalized interest compared to the prior year.

Depreciation expense increased $29,888,000, or 3.7%, in 2024 compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities, partially offset by dispositions.

General and administrative expense increased $1,163,000, or 1.5%, in 2024 as compared to the prior year, primarily due to an increase in legal and professional fees, partially offset by decreased compensation expense, including severance.

Casualty and impairment loss for the year ended December 31, 2024 of $2,935,000 was due to flooding and water damage at communities in California from extensive rainfall and a fire at a community in New Jersey.

Income from unconsolidated investments increased $37,228,000 in 2024 compared to the prior year, primarily due to realized and unrealized property technology investments gains, partially offset by the recognition of $1,519,000 of our promoted interest associated with the achievement of a threshold return with the U.S. Fund in the prior year.

Gain on sale of communities increased in 2024 compared to the prior year. The amount of gain realized in a given period depends on many factors, including the number of communities sold, the size and carrying value of the communities sold, expected operating performance of the communities and the market conditions in the local area. The gains of $363,300,000 and $287,424,000 in 2024 and 2023, respectively, were primarily due to the sale of eight and four wholly-owned communities in 2024 and 2023, respectively.

Income tax expense of $10,153,000 for 2023 was primarily related to The Park Loggia.

Non-GAAP Financial Measures — Reconciliation of FFO and Core FFO

FFO and FFO adjusted for non-core items, or "Core FFO," as defined below, are generally considered by management to be appropriate supplemental measures of our operating and financial performance.

Consistent with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts® ("Nareit"), we calculate Funds from Operations Attributable to Common Stockholders ("FFO") as net income or loss attributable to common stockholders computed in accordance with GAAP, adjusted for:

•gains or losses on sales of previously depreciated operating communities;

•cumulative effect of a change in accounting principle;

•impairment write-downs of depreciable real estate assets;

•write-downs of investments in affiliates due to a decrease in the value of depreciable real estate assets held by those affiliates;

•depreciation of real estate assets; and

•similar adjustments for unconsolidated partnerships and joint ventures, including those from a change in control.

FFO can help with the comparison of the operating and financial performance of a real estate company between periods or as compared to different companies because the adjustments such as (i) gains or losses on sales of previously depreciated property or (ii) real estate depreciation may impact comparability as the amount and timing of these or similar items can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates. By further adjusting for items that we do not consider part of our core business operations, Core FFO can help with the comparison of our core operating performance year over year. We believe that, in order to understand our operating results, FFO and Core FFO should be considered in conjunction with net income as presented in the Consolidated Statements of Comprehensive Income included elsewhere in this report.

We calculate Core FFO as FFO, adjusted for:

•joint venture gains (if not adjusted through FFO), non-core costs and promoted interests from partnerships;

•casualty and impairment losses or gains, net on non-depreciable real estate or other investments;

•gains or losses from early extinguishment of consolidated borrowings;

•expensed transaction, development and other pursuit costs, net of recoveries;

•legal recoveries, settlement proceeds, and certain legal costs;

•property and casualty insurance proceeds;

•gains or losses on sales of assets not subject to depreciation and other investment gains or losses;

•advocacy contributions, representing payments to promote our business interests;

•hedge ineffectiveness or gains or losses from derivatives not designated as hedges for accounting purposes;

•changes to expected credit losses associated with the lending commitments under the SIP;

•severance related costs;

•executive transition compensation costs;

•net for-sale condominium activity, including gains, marketing, operating and administrative costs and imputed carry cost; and

•income taxes.

FFO and Core FFO do not represent (i) net income in accordance with GAAP, and therefore should not be considered an alternative to net income, which remains the primary measure, as an indication of our performance, or (ii) cash generated from operating activities in accordance with GAAP, and therefore should not be considered an alternative to net cash flows from operating activities, as determined by GAAP, as a measure of liquidity. In addition, FFO and Core FFO are not necessarily indicative of cash available to fund cash needs and may not be comparable to FFO and Core FFO as calculated by other REITs.

Liquidity and Capital Resources

We employ a disciplined approach to our liquidity and capital management. When we source capital, we take into account both our view of the most cost-effective alternative available and our desire to maintain a balance sheet that provides us with flexibility. Our principal focus on near-term and intermediate-term liquidity is to ensure we have adequate capital to fund:

•development and redevelopment activity in which we are currently engaged or in which we plan to engage;

•the minimum dividend payments on our common stock required to maintain our REIT qualification under the Code;

•regularly scheduled principal and interest payments and principal payments either at maturity or opportunistically before maturity;

•normal recurring operating and corporate overhead expenses; and

•investment in our operating platform, including strategic investments.

Factors affecting our liquidity and capital resources are our cash flows from operations, financing activities and investing activities (including dispositions) as well as general economic and market conditions. Cash flows from operations are determined by operating activities and factors including but not limited to (i) the number of apartment homes currently owned, (ii) rental rates, (iii) occupancy levels, (iv) uncollectible lease revenue levels or interruptions in collections caused by market conditions and (v) operating expenses with respect to apartment homes. The timing and type of capital markets activity in which we engage is affected by changes in the capital markets environment, such as changes in interest rates or the availability of cost-effective capital. Our plans for development, redevelopment, non-routine capital expenditure, acquisition and disposition activity are affected by market conditions and capital availability. We frequently review our liquidity needs, especially in periods with volatile market conditions, as well as the adequacy of cash flows from operations and other expected liquidity sources to meet these needs.

We had cash, cash equivalents and restricted cash of $267,076,000 at December 31, 2024, a decrease of $263,884,000 from $530,960,000 at December 31, 2023. The following discussion relates to changes in cash, cash equivalents and restricted cash due to operating, investing and financing activities.

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

For the year ended December 31,

Net cash used in investing activities $ (996,864) $ (928,955)

Net cash used in financing activities $ (874,898) $ (834,359)

•Net cash provided by operating activities increased primarily due to increases in NOI.

•Net cash used in investing activities was primarily due to (i) the investment of $951,101,000 in the development and redevelopment of communities, (ii) acquisition of six wholly-owned communities for $464,419,000 and (iii) capital expenditures of $198,026,000 for our wholly-owned communities and non-real estate assets. These amounts were partially offset by net proceeds from the disposition of eight wholly-owned communities.

•Net cash used in financing activities was primarily due to (i) payment of cash dividends in the amount of $961,914,000, and (ii) the repayment of the $300,000,000 fixed rate unsecured notes. These amounts were partially offset by the proceeds from the issuance of unsecured notes in the amount of $398,788,000.

Variable Rate Unsecured Credit Facility

The $2,250,000,000 Credit Facility matures in September 2026. The interest rate that would be applicable to borrowings under the Credit Facility is 5.19% at January 31, 2025 and is composed of (i) the Secured Overnight Financing Rate ("SOFR"), applicable to the period of borrowing for a particular draw of funds from the facility (e.g., one month to maturity, three months to maturity, etc.), plus (ii) the current borrowing spread to SOFR of 0.805% per annum, which consists of a 0.10% SOFR adjustment plus 0.705% per annum, assuming a daily SOFR borrowing rate. The borrowing spread to SOFR can vary from SOFR plus 0.63% to SOFR plus 1.38% based upon the rating of our unsecured senior notes. There is also an annual facility commitment fee of 0.12% of the borrowing capacity under the facility, which can vary from 0.095% to 0.295% based upon the rating of our unsecured senior notes. The Credit Facility contains a sustainability-linked pricing component which provides for interest rate margin and commitment fee reductions or increases by meeting or missing targets related to environmental sustainability, specifically greenhouse gas emission reductions, with the adjustment determined annually. The annual determination under the sustainability-linked pricing component occurred in July 2024, maintaining reductions of approximately 0.02% to the interest rate margin and 0.005% to the commitment fee due to our achievement of sustainability targets.

The availability on the Credit Facility as of January 31, 2025 is as follows (dollars in thousands):

Credit Facility commitment $2,250,000

Credit Facility outstanding —

Commercial paper outstanding (170,000)

Letters of credit outstanding (1) (964)

Total Credit Facility available $ 2,079,036

_____________________________________

(1)In addition, we had $47,592 outstanding in additional letters of credit unrelated to the Credit Facility as of January 31, 2025.

Commercial Paper Program

We have a Commercial Paper Program with the maximum aggregate face or principal amount outstanding at any one time not to exceed $500,000,000. Under the terms of the Commercial Paper Program, we may issue, from time to time, unsecured commercial paper notes with varying maturities of less than one year. The Commercial Paper Program is backstopped by our commitment to maintain available borrowing capacity under the Credit Facility in an amount equal to actual borrowings under the Commercial Paper Program. As of January 31, 2025, we had $170,000,000 outstanding under the Commercial Paper Program at a weighted average contractual interest rate of 4.55%.

Secured and Unsecured Borrowings— Financial Covenants and Early Repayment Provisions

We are subject to financial covenants contained in the Credit Facility and the indentures under which our unsecured notes were issued. The principal financial covenants include the following:

•limitations on the amount of total and secured debt in relation to our overall capital structure;

•limitations on the amount of our unsecured debt relative to the undepreciated basis of real estate assets that are not encumbered by property-specific financing; and

•minimum levels of debt service coverage.

We were in compliance with these covenants at December 31, 2024.

In addition, some of our secured and unsecured borrowings include yield maintenance, defeasance, or prepayment penalty provisions, which could result in us incurring an additional charge in the event of a full or partial prepayment of outstanding principal before the scheduled maturity. These provisions in our borrowings are generally consistent with other similar types of debt instruments issued during the same time period in which our borrowings were issued.

Continuous Equity Offering Program

Under our continuous equity program (the "CEP"), we may sell (and/or enter into forward sale agreements for the sale of) up to $1,000,000,000 of our common stock from time to time. Actual sales will depend on a variety of factors to be determined, including market conditions, the trading price of our common stock and our determinations of the appropriate funding sources. We expect that, if entered into, we will physically settle each forward sale agreement on one or more dates prior to the maturity date of that particular forward sale agreement, and to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the forward sale price. However, we may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, we will pay the forward seller, in the form of a reduced initial forward sale price, a commission of up to 1.5% of the sales prices of all borrowed shares of common stock sold. During 2024 and through January 31, 2025, we entered into forward contracts under the CEP to sell 367,113 shares of common stock for approximate proceeds, net of fees, of $80,687,000, based on the gross weighted average price of $223.27 per share, with settlement of the forward contracts to occur on one or more dates not later than December 31, 2025. The final proceeds will be determined on the date(s) of settlement and are subject to certain customary adjustments for our dividends and a daily interest factor. As of January 31, 2025, we had $623,997,000 remaining authorized for issuance under this program, after consideration of the forward contracts.

Forward Equity Offering

In addition to the CEP, during the year ended December 31, 2024, we completed an underwritten public offering of 3,680,000 shares of our common stock at a discount to the closing price of $226.52 per share, net of offering fees, offered in connection with forward contracts entered into with certain financial institutions acting as forward purchasers. Assuming full physical settlement of the forward contracts, which we expect to occur no later than December 31, 2025, we will receive approximate proceeds, net of offering fees and discounts, of $808,606,000, based on the initial forward price. The final proceeds will be determined on the date(s) of settlement and are subject to certain customary adjustments for our dividends and a daily interest factor.

Stock Repurchase Program

We have a stock repurchase program under which we may acquire shares of our common stock in open market or negotiated transactions up to an aggregate purchase price of $500,000,000 (the "Stock Repurchase Program"). Purchases of common stock under the Stock Repurchase Program may be exercised at our discretion with the timing and number of shares repurchased depending on a variety of factors including price, corporate and regulatory requirements and other corporate liquidity requirements and priorities. The Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. During the year ended December 31, 2024 through January 31, 2025, we had no repurchases of shares under this program. As of January 31, 2025, we had $314,237,000 remaining authorized for purchase under this program.

Interest Rate Swap Agreements

The following derivative activity occurred during the year ended December 31, 2024:

•In connection with the issuance of our $400,000,000 unsecured notes in May 2024 maturing in 2034, we terminated $250,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of unsecured notes, receiving $16,839,000 which will be recognized over the life of the unsecured notes as a reduction in the effective interest rate. Of the $250,000,000 forward interest rate swap agreements that terminated, $50,000,000 were entered into during 2024. The Company has deferred these gains in accumulated other comprehensive income on the accompanying Consolidated Balance Sheets, and is recognizing the impact as a component of interest expense, net, over the term of the respective hedged debt.

•In addition to the activity above, we entered into and had outstanding $100,000,000 of forward interest rate swap agreements to reduce the impact of variability in interest rates on a portion of our anticipated future debt issuance activity through December 31, 2025. We expect to cash settle the swaps and either pay or receive cash for the then current fair value. Assuming the Company issues the debt as expected, the hedging impact from these positions will then be recognized over the life of the issued debt as a yield adjustment.

Future Financing and Capital Needs—Debt Maturities and Material Obligations

46

Table of Contents

One of our principal long-term liquidity needs is the repayment of long-term debt at maturity. For both our unsecured and secured notes, a portion of the principal of these notes may be repaid prior to maturity. Early retirement of our unsecured or secured notes could result in gains or losses on extinguishment. We may use capital from a variety of sources to repay debt at maturity, including proceeds received from the dispositions of our operating communities or other direct and indirect investments in real estate and cash from operations. If we do not have funds on hand sufficient to repay our indebtedness as it becomes due, it will be necessary for us to refinance or otherwise provide liquidity to satisfy the debt at maturity. This refinancing may be accomplished by uncollateralized private or public debt offerings, equity issuances, including through the settlement of the outstanding equity forwards, additional debt financing that is secured by mortgages on individual communities or groups of communities or borrowings under our Credit Facility or Commercial Paper Program. In addition, to the extent we have amounts outstanding under the Commercial Paper Program, we are obligated to repay the short-term indebtedness at maturity through either current cash on hand or by incurring other indebtedness, including by way of borrowing under our Credit Facility. Although we believe we will have the capacity to meet our currently anticipated liquidity needs, we cannot assure you that capital from additional debt financing or debt or equity offerings will be available or, if available, that they will be on terms we consider satisfactory.

In May 2024, we issued $400,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement for proceeds net of underwriting fees of approximately $396,188,000, before considering the impact of other offering costs. The notes mature in June 2034 and were issued at a 5.35% interest rate, resulting in a 5.05% effective rate including the impact of offering costs and hedging activity.

The following table details our consolidated debt obligations, including the effective interest rate and contractual maturity dates, and principal payments for periodic amortization and maturities for the next five years, excluding our Credit Facility and Commercial Paper Program and amounts outstanding related to communities classified as held for sale at December 31, 2024 and 2023 (dollars in thousands). We are not directly or indirectly (as borrower or guarantor) obligated in any material respect to pay principal or interest on the indebtedness of any unconsolidated entities in which we have an equity or other interest, other than as disclosed related to the AVA Arts District construction loan (see "Unconsolidated Operating Communities" for further discussion of the construction loan).

In addition to consolidated debt, we have scheduled contractual obligations associated with (i) ground leases for land underlying current operating or development communities and commercial and parking facilities and (ii) office leases for our corporate headquarters and regional offices of $16,433,000 for 2025, $16,843,000 for 2026 and $486,656,000 thereafter.

Future Financing and Capital Needs—Portfolio and Capital Markets Activity

We invest in various real estate and real estate related investments, which include (i) the acquisition, development and redevelopment of communities both wholly-owned and through the formation of joint ventures, (ii) other indirect investments in real estate through the SIP, all as discussed further below and (iii) investments in other real estate-related ventures through direct and indirect investments in property technology and environmentally focused companies and investment management funds.

In 2025, we expect to continue to meet our liquidity needs from one or more of a variety of internal and external sources, which may include (i) settlement of our outstanding equity forward contracts, (ii) real estate dispositions, (iii) cash balances on hand as well as cash generated from our operating activities, (iv) borrowing capacity under the Credit Facility, (v) borrowings under the Commercial Paper Program and (vi) secured and unsecured debt financings. Additional sources of liquidity in 2025 may include the issuance of common and preferred equity, including the issuance of additional shares of our common stock under the CEP. Our ability to obtain additional financing will depend on a variety of factors, such as market conditions, the general availability of credit, the overall availability of credit to the real estate industry, our credit ratings and credit capacity, as well as the perception of lenders regarding our long or short-term financial prospects.
