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 the COVID-19 pandemic’s impact on multifamily rental housing

The national and global impacts of the COVID-19 pandemic (including the impact of new strains of the original virus) continue to evolve. Regulatory measures have at times included varying requirements for social distancing, limitations on landlords' rights with respect to delinquent tenants, and restrictions on travel, congregation and business operations. Business and consumer preferences for work and living arrangements during the pandemic continue to evolve as well. The long-term impact of COVID-19 on the economy remains uncertain. The COVID-19 pandemic continues to present material uncertainty and risk with respect to our performance, financial condition, results of operations and cash flows. Moreover, many of the risk factors set forth in this Form 10-K should be interpreted as heightened risks as a result of the impact of the COVID-19 pandemic. In addition, if in the future there is an outbreak of another highly infectious or contagious disease, the Company and our properties may be subject to similar risks as the risks posed by COVID-19.

Regulatory, business and consumer responses to the COVID-19 pandemic impact our operations.

Operating impacts from the COVID-19 pandemic include the following:

•Numerous state, local, and federal entities imposed restrictions, for varying times and to varying degrees, on our ability to enforce residents’ contractual lease obligations, and this will continue to affect our ability (until a restriction is lifted or expires) to enforce all our remedies (such as pursuing collections and seeking evictions) for the failure to pay rent.

•Consumers whose income has declined, who are working remotely or who cannot freely access neighborhood amenities like restaurants, gyms and entertainment venues, may decide to live in a location other than our markets. For as long as interest rates remain low and health concerns remain, consumers who would otherwise rent a multifamily apartment may opt instead to rent a single family home or purchase a home. Demand from students and demand for corporate apartment homes have been and may continue to be negatively impacted by trends in remote learning and work, and the adoption of new online technologies.

•Various state, local and federal rules required us, in some jurisdictions or for some properties, to waive late fees and certain other customary fees associated with our apartment rental business, and may do so in the future. We have elected at times also to waive these fees even where or when not required, and may do so in the future. These requirements or practices have resulted, and to the extent implemented or continued may in the future result, in foregone revenue.

•Our properties may 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.

•Social distancing and other measures have caused us from time to time to revise the manner in which we meet with prospective residents and serve current residents. For example, prospective residents visiting apartments may do so virtually or on a self-tour rather than being accompanied by a leasing consultant. In addition, in many communities, access to various common areas may be limited. These factors may affect resident satisfaction and leasing velocity.

•There are growing concerns related to the general economy about (i) supply chain constraints caused by business challenges resulting from the pandemic and (ii) inflation caused by both supply chain constraints and governmental fiscal and monetary policies. Supply chain constraints could cause delays in our construction and redevelopment activity, and inflation could cause our construction and operating costs to increase. In the event that our rents and rental revenue do not increase sufficiently to offset increases in construction and operating costs, our operating results would be negatively impacted.

In addition to renting apartment homes directly to residents, we also lease ancillary commercial space at our communities and lease apartment homes to corporate apartment home providers. In 2021, 1.4% of our total revenue was from commercial tenants and 2.1% of our total residential revenue was from corporate apartment home providers. To the extent that the pandemic or any associated government restrictions have adverse impacts on the businesses of our commercial tenants, or demand from corporate apartment home providers, we may experience elevated delinquencies for these tenants. There may also be a greater risk of bankruptcy and default from commercial and corporate apartment home providers.

Emergency orders shutting down non-essential businesses, limiting congregations of people, and requiring social distancing have at times disrupted, and may in the future disrupt, our development and construction activity. To the extent we experience delays in construction, our construction costs may increase 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. Many associates, particularly in overhead positions, are working remotely. This disruption in the normal operations of our workforce, as well as the possibility of illness among our associates or a substantial portion of our workforce, could also adversely affect our operations.

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 home 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 may 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, 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;

•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 includes acquiring as well as developing communities. Our acquisition activities may be exposed to the following risks:

•an acquired property may fail to perform as we expected in analyzing our investment; and

•our estimate of the costs of operating, repositioning or redeveloping an acquired property may prove inaccurate.

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.

10

Table of Contents

We may from time to time commence development activity or make acquisitions outside of our existing market areas if appropriate opportunities arise. 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.

We also may engage or have an interest in for-sale activity, such as the sale of the residential condominiums 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 are exposed to risks associated with investment in, and management of, discretionary real estate investment funds and joint ventures and technology and environmentally focused companies.

At times we invest directly and indirectly in real estate as a partner or a co-venturer with other investors or in technology and environmentally focused companies. 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, at a time when we otherwise would not have initiated such a transaction and on terms that are not most advantageous to us.

Our investments in technology companies, or in funds that invest in technology companies, are generally held through taxable REIT subsidiaries 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 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 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.

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 primarily use external financing 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

11

Table of Contents

repayment of debt, such as selling assets, reducing our cash dividend or issuing equity. 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. We believe that the lenders under our Credit Facility will fulfill their lending obligations thereunder, but if economic conditions deteriorate, the ability of those lenders to fulfill their obligations may be adversely impacted.

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.

If interest rates increase, our interest costs on variable rate debt will rise unless 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.

From time to time we use interest rate derivatives to hedge and manage our exposure to certain interest rate risks. 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 the Company if interest rates decline. The settlement or termination of interest rate hedging contracts may involve material charges to our earnings including net costs, such as transaction fees, settlement costs and/or breakage costs. In addition, our use of interest rate hedging arrangements may expose us to additional risks, including a risk that a counterparty to a hedging arrangement may fail to honor its obligations. Developing and implementing an interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations and there can be no assurance that our hedging activities will be effective.

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 tax-exempt financing, or as a condition to obtaining favorable zoning or 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, 2021, 4.9% 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 and, as a consequence, adversely affect the value of the 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.

Some of our tax-exempt bond financing documents require us to obtain a guarantee from a financial institution of payment of the principal and interest on the bonds. The guarantee may take the form of 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 with a syndicate of commercial banks. 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

12

Table of Contents

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 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.

The phase-out of LIBOR and transition to SOFR as a benchmark interest rate will have uncertain and possibly adverse effects.

In 2018, the Alternative Reference Rate Committee (the "AARC") recommended the Secured Overnight Financing Rate (“SOFR”) as the alternative to LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities, published by the Federal Reserve Bank of New York. While we expect LIBOR to be available in substantially its current form until at least the end of June 30, 2023, it is possible that LIBOR will become unavailable prior to that point. Due to the broad use of LIBOR as a reference rate, the impact of this transition on the interest rates charged to the Company could possibly adversely affect our financing costs, including spread pricing on our Credit Facility and variable rate unsecured term loans (the "Term Loans") and certain other floating rate debt obligations, as well as our operations and cash flows. Additionally, although SOFR is the AARC's recommended replacement rate, it is also possible that lenders may instead choose alternative replacement rates that may differ from LIBOR in ways similar to SOFR or in ways that would result in higher interest costs for us. It is not yet possible to predict the magnitude of LIBOR's end on our borrowing costs given the remaining uncertainty about which rate(s) will replace LIBOR.

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.

Potential difficulties in promptly selling real estate at prices we find acceptable 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” section for more information on federal tax law risks.

Risks related to ongoing operations of our communities

Rent control and other changes in applicable laws, or noncompliance with applicable laws, 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

13

Table of Contents

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 other conditions, (ii) rent control or rent stabilization laws or other residential landlord/tenant laws, or (iii) 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.

We have seen a recent increase in states and municipalities implementing, considering or being urged by advocacy groups to consider rent control or rent stabilization laws and regulations or take other actions that could limit the amount by which we can raise rents or charge non-rent fees. For example, in 2019 the State of California adopted statewide rent control for communities older than fifteen years, limiting rent increases to the lesser of 10% or 5% plus local CPI. Also in 2019 the State of New York adopted new rules for rent-controlled and rent-stabilized units that revised and limited 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. Current and future enactments of rent control or rent stabilization laws or other laws regulating multi-family housing may limit our ability to charge market rents, increase rents, 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.

Short-term leases expose us to the effects of declining market rents.

Substantially all 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 on-line 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 markets 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 commercial 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 2021. 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. The presence of competitive alternatives may affect our ability to lease space and the level of rents we can obtain. 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.

Risks related to our REIT or tax status

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 this qualification.

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 taxable REIT subsidiaries that a REIT could not engage in directly. We also use taxable REIT subsidiaries to hold certain assets that we believe would be subject to the 100% prohibited transaction tax if sold at a gain outside of a taxable REIT subsidiary or to engage in activities that generate non-qualifying REIT income. Our taxable REIT subsidiaries are subject to federal income tax as regular corporations.

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.

We may experience regulatory and federal tax barriers to selling apartment communities that could limit financial flexibility.

Federal tax laws may limit our ability to earn a gain on the sale of a community (unless we own it through a subsidiary which will incur a taxable gain upon sale) if we are found to have held, acquired or developed the community primarily with the intent to resell the community, and this limitation may affect our ability to sell communities without adversely affecting returns to our stockholders.

From time to time we dispose of 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 tax consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax deferred basis.

We may be subject to adverse legislative or regulatory tax changes that could reduce the market price of our common stock or debt securities.

15

Table of Contents

At any time, the federal income tax laws governing REITs or the administrative interpretations of those laws may be amended. We cannot predict when or if any new federal income tax law, regulation, or administrative interpretation, or any amendment to any existing federal income tax law, regulation or administrative interpretation, will be adopted, promulgated or become effective and any such law, regulation, or interpretation may take effect retroactively. We and our stockholders and holders of our debt securities could be adversely affected by any such change in, or any new, federal income tax law, regulation or administrative interpretation.

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 the Company's view, economically impractical. Incidents that directly or indirectly damage our communities, both physically and financially, or cause losses that exceed our insurance coverage 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 and severe or inclement weather 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.

•Terrorism and other risk. We have significant investments in large 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 losses arising from 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 the Company's view, economically impractical.

We may incur costs related to climate change.

To the extent that significant changes in the climate occur in areas where our communities are located, we may experience extreme weather and changes in precipitation and temperature, all of which may result in physical damage to or a decrease in demand for properties located in these areas or affected by these conditions. In addition, changes in 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, requiring retrofitting of existing systems) 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 net income.

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 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 the manner in which our communities

16

Table of Contents

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.

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, from time to time we 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 in some instances 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.

17

Table of Contents

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 Securities 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. Maryland law restricts some business combinations and requires compliance with statutory procedures before some mergers and acquisitions may occur, which may delay or prevent offers to acquire us or increase the difficulty of completing any offers, 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.

Changes in U.S. accounting standards may materially and adversely affect the reporting of our operations.

The Company follows 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 issue new accounting pronouncements or 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.

Information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyber attacks.

We collect and hold personally identifiable information of our residents and prospective residents in connection with our leasing and property management activities, and we collect and hold personally identifiable information of our associates in connection with their employment. In addition, we engage third party service providers that may have access to such personally identifiable information in connection with providing necessary information technology and security and other business services to us.

There can be no assurance that we will be able to prevent unauthorized access to this information. Any failure in or breach of our operational or information security systems, or those of our third party service providers, as a result of cyber attacks or information security breaches, could result in a wide range of potentially serious harm to our business operations and financial prospects, including (among others) disruption of our business and operations, disclosure or misuse of confidential or proprietary information (including personal information 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 websites for use by residents and prospective residents, including requirements related to accessibility of our websites to persons with disabilities and our handling and use of data we collect. We could face liabilities for failure to comply with these requirements. New statutes, such as the California Consumer Privacy Act (“CCPA”), and related regulations 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.

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. Our executive officers make important capital allocation decisions or recommendations to our Board of Directors from among the

opportunities identified by our regional offices. There is substantial competition for qualified personnel in the real estate industry, and the loss of our key personnel could adversely affect the Company.

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, Lease-Up 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. The following is a description of each category:

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

•Same Store for the year ended December 31, 2021 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 respective prior year period. For the year ended December 31, 2021, Same Store communities are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2020, are not conducting or are not probable to conduct substantial redevelopment activities and are not held for sale or probable for disposition to unrelated third parties within the current year. 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, 2021, or which were acquired subsequent to January 1, 2020. Other Stabilized includes stabilized operating communities in Charlotte, North Carolina and Dallas, Texas, the two new expansion markets we entered in 2021, but excludes communities that are conducting or are probable to conduct substantial redevelopment activities within the current year, as defined below.

•Lease-Up is composed of consolidated communities where construction has been complete for less than one year and that do not have stabilized occupancy.

•Redevelopment is composed of consolidated communities where substantial redevelopment is in progress or is probable to begin during the current year. Redevelopment is considered substantial when (i) capital invested during the reconstruction effort 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, or were under construction and were completed during the current year. These communities may be partially or fully complete and operating.

Unconsolidated Development is composed of communities that are either currently under construction, or were under construction and were completed during the current year, in which we have an indirect ownership interest through our investment interest in an unconsolidated joint venture. 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) We remove a community from our Same Store portfolio if we believe that planned activity for the upcoming year will result in that community's expected operations not being comparable to the prior year, including (i) when we intend to undertake a significant capital renovation, such that the community will be classified as a Redevelopment community; (ii) when we intend to dispose of a community; or (iii) when a significant casualty loss occurs.

(2) Community was moved from the Same Store portfolio to the Other Stabilized portfolio as a result of a casualty loss that occurred during the year and impacted operations.

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, 2022, 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.

Our Current Communities are located in the following geographic markets:

North Carolina — 3 — 500 — % 0.6 %

Charlotte, NC — 3 — 500 — % 0.6 %

We manage and operate substantially all of our Current Communities. During the year ended December 31, 2021, we completed construction of nine communities containing 2,752 apartment homes and sold 11 operating communities containing 2,933 apartment homes. The age of our Current Communities, on a weighted average basis according to number of apartment homes, is 19.7 years. When adjusted to reflect redevelopment activity, as if redevelopment were a new construction completion date, the weighted average age of our Current Communities is 10.6 years.

Of the Current Communities, as of January 31, 2022, we owned (directly or through wholly-owned subsidiaries):

•266 operating communities, including 259 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 April 2106, and three of the land leases are used to support tax advantaged structures that ultimately allow us to purchase the land upon lease expiration.

Table of Contents

•A general partnership interest in Archstone Multifamily Partners AC LP (the “U.S. Fund”), subsidiaries of which own three operating communities.

•A membership interest in four 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 three ventures that each hold a fee simple interest in an operating community, one of which is consolidated for financial reporting purposes.

•A general partnership interest in one partnership structured as a “DownREIT,” which is consolidated and owns one community. In this partnership, one of our wholly-owned subsidiaries is the general partner. Limited partners are entitled to receive an initial distribution before any distribution is made to the general partner. The distributions per unit paid to the holders of units of limited partnership interests are equal to our current common stock dividend amount. The limited partnership interests have the right to present all or some of their units for redemption for a cash amount based on the fair value of our common stock. In lieu of a cash redemption by the partnership, we may elect to acquire any unit presented for redemption for one share of our common stock. At January 31, 2022, there were 7,500 DownREIT partnership units outstanding.

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, a membership interest in two limited liability companies that each hold an interest in an Unconsolidated Development Community, and a wholly-owned mixed-use project with for-sale condominiums.

Development Communities

As of December 31, 2021, 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 5,386 apartment homes and 40,000 square feet of commercial space to our portfolio for a total capitalized cost, including land acquisition costs, of approximately $2,140,000,000. 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.

(2)AVA Hollywood at La Pietra Place contains 19,000 square feet of commercial space.

Unconsolidated Development Communities

During 2020, we entered into a joint venture to develop, own, and operate AVA Arts District, an apartment community located in Los Angeles, CA, which is currently under construction and expected to contain 475 apartment homes and 56,000 square feet of commercial space when completed. We own a 25.0% interest in the venture and contributed our total required equity investment of $30,436,000. The venture has secured a $167,147,000 variable rate construction loan to fund approximately 60% of the development of AVA Arts District, of which $11,581,000 has been drawn as of December 31, 2021. We have guaranteed the construction loan on behalf of the venture, and any obligations under the construction loan guarantee, except for obligations arising from our misconduct, are required capital contributions of the partners based on ownership interest.

In addition, we have a 50.0% interest in Avalon Alderwood MF Member, LLC, a joint venture to develop, own, and operate Avalon Alderwood Mall, a 328 apartment home community located in Lynnwood, WA. Avalon Alderwood Mall, which is currently under construction, began leasing in 2021 with physical occupancy of 8% as of December 31, 2021.

As of December 31, 2021, we had an indirect interest in the following Unconsolidated Development Communities.

Development Rights

At December 31, 2021, we had $147,546,000 in acquisition and related capitalized costs for direct interests in seven land parcels we own. In addition, we had $40,414,000 in capitalized costs (including legal fees, design fees and related overhead costs) related to (i) 14 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 three Development Rights that are additional development phases of existing stabilized operating communities we own and which will be constructed on land currently adjacent to or directly associated with those operating communities for which we own the land. Collectively, the land held for development and associated costs for deferred development rights relate to 24 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 8,070 apartment homes to our portfolio. Substantially all of these apartment homes will offer features like those offered by the communities we currently own.

The properties comprising 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 2021, we incurred a charge of $3,231,000 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.

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

Land Acquisitions

We select land for development and follow established procedures that we believe minimize both the cost and the risks of development. During 2021, we acquired the following land parcels for an aggregate investment of $174,224,000.

(2)Construction on this land parcel commenced during 2021.

Disposition Activity

We sell assets when they do not meet our long-term investment strategy or when real estate markets allow us to realize a portion of the value created over our periods of ownership, 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 retain the cash proceeds on our balance sheet until it is redeployed into acquisition, development or redevelopment activity. On occasion, 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, 2021 to January 31, 2022, we sold our interest in nine wholly-owned operating communities, containing 2,404 apartment homes, with an aggregate gross sales price of $867,200,000.

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 10% of the second $25,000,000 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. 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.

Our Southeast Florida communities are in wind exposed locations that 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.

29

Table of Contents

Our communities 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 are subject to certain coverage limitations and exclusions. 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.

We also maintain certain casualty policies (general liability, umbrella/excess and workers compensation) for construction related risks that have various exclusions and deductibles that, in management’s view, are commercially reasonable.

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 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 exclusion 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 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, 2022 there were 431 holders of record of an aggregate of 139,752,486 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 2022, we announced that our Board of Directors declared a dividend on our common stock for the first quarter of 2022 of $1.59 per share, consistent with our previous quarterly dividend. The dividend will be payable on April 15, 2022 to all common stockholders of record as of March 31, 2022.

Executive Overview

2021 Financial Highlights

Net income attributable to common stockholders for the year ended December 31, 2021 was $1,004,299,000, an increase of $176,669,000, or 21.3%, over the prior year. The increase is primarily attributable to increases in real estate sales and related gains, as well as increased NOI in the current year from Development and newly acquired communities. These amounts were partially offset by a decrease in NOI from Same Store and communities sold in 2020 and 2021, and an increase in depreciation expense in the current year.

Same Store NOI attributable to our apartment rental operations, including parking and other ancillary residential revenue ("Residential"), for the year ended December 31, 2021 was $1,370,282,000, a decrease of $66,283,000, or 4.6%, from the prior year. The decrease was due to a decrease in rental revenue of $45,643,000, or 2.2%, as well as an increase in property operating expenses of $20,300,000, or 3.2%, over 2020.

During 2021, we raised approximately $2,138,184,000 of gross capital through the issuance of unsecured notes; sale of common shares under our fifth continuous equity program ("CEP V"); and the sale of nine consolidated operating communities, condominiums at The Park Loggia and other real estate. This amount does not include our share of proceeds from joint venture dispositions. We believe that our current capital structure will continue to provide financial flexibility to access capital on attractive terms.

We believe our development activity will continue to create long-term value. During 2021, we:

•Completed the construction of nine consolidated apartment communities containing an aggregate of 2,752 apartment homes and 29,000 square feet of commercial space, for an aggregate total capitalized cost of $1,070,000,000.

•Started the construction of 10 consolidated apartment communities containing an aggregate of 3,010 apartment homes, which are expected to be completed for an estimated total capitalized cost of $1,246,000,000.

We also achieved portfolio growth through acquisitions, acquiring seven consolidated apartment communities containing an aggregate of 1,932 apartment homes and 90,000 square feet of commercial space for an aggregate purchase price of $724,500,000.

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; borrowings under our Credit Facility; secured debt; the issuance of corporate securities (which could include unsecured debt, preferred equity and/or common equity); the sale of apartment communities; or through the formation of joint ventures. See the discussion under "Liquidity and Capital Resources."

COVID-19 Pandemic

In response to the COVID-19 pandemic, we adjusted our business operations to address the safety of and financial impacts on our residents and associates, including, in certain jurisdictions (i) providing flexible lease renewal options, (ii) creating payment plans for residents who are impacted by COVID-19 and (iii) waiving late fees and certain other customary fees associated with apartment rentals. To the extent still implemented, we may discontinue these measures at any time except where required by law.

The impact on our consolidated results of operations from COVID-19 for future periods will depend, among other factors, on (i) the effect on the multifamily industry and the general economy of measures taken by businesses and the government to address COVID-19 and any variants and relieve the economic distress of consumers, such as governmental limitations on the ability of multifamily owners to evict residents who are delinquent in the payment of their rent, and (ii) the preferences of consumers and businesses for living and working arrangements both during and after the pandemic.

The COVID-19 pandemic continues to impact our collections and associated outstanding receivables, with the impact partially mitigated by payments received under government rent relief programs. The following table presents, for our 2021 Same Store communities for the periods presented, the percentages of the following charges to residents that we have collected, including (i) apartment base rent and (ii) other rentable items, such as parking and storage rent, along with pet and other recurring fees in accordance with residential leases (collectively, "Collected Residential Revenue," which excludes transactional fees). Included in collections are $28,286,000 of aggregate rent relief payments received for our Same Store portfolio during the year ended December 31, 2021.

_________________________

(1)Collections are for our 2021 Same Store communities and exclude commercial revenue, which was 1.0% of our 2021 Same Store total revenue.

(2)The Collected Residential Revenue percentage as of the last day in the respective quarter.

(3)The percentage of Collected Residential Revenue as of January 31, 2022.

(4)Collected Residential Revenue for January 2022 as of January 31, 2022 was 93.0%.

The collection rates are based on resident activity as reflected in our property management systems and are presented to provide information about collections trends during the COVID-19 pandemic. Prior to the COVID-19 pandemic, the collections information provided was not routinely produced for internal use by senior management or publicly disclosed by the Company and is a result of analysis that is not subject to internal controls over financial reporting. This information is not prepared in accordance with GAAP, does not reflect GAAP revenue or cash flow metrics and may be subject to adjustment in preparing GAAP revenue and cash flow metrics. Additionally, this information should not be interpreted as predicting the Company’s financial performance, results of operations or liquidity for any period. As of December 31, 2021 and 2020, the outstanding rent receivable balance for residential and commercial tenants, net of reserves, was $18,594,000 and $18,159,000, respectively.

Communities Overview

As of December 31, 2021 we owned or held a direct or indirect ownership interest in 297 apartment communities containing 87,992 apartment homes in 12 states and the District of Columbia, of which 17 consolidated communities were under development and one community was under redevelopment. We have an indirect interest in 12 of the 297 apartment communities which were owned by entities that were not consolidated for financial reporting purposes, including two that are being developed within joint ventures. In addition, we held a direct or indirect ownership interest in Development Rights to develop an additional 24 communities that, if developed as expected, will contain an estimated 8,070 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

34

Table of Contents

communities, Other Stabilized communities, Lease-Up 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. Lease-Up communities are consolidated communities where construction has been complete for less than one year and does not have stabilized occupancy. Redevelopment communities are consolidated communities where substantial redevelopment is in progress or is probable to begin during the fiscal year. Unconsolidated communities are communities in which we have an indirect ownership interest through our investment interest in an unconsolidated entity. 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 year-over-year operating performance is primarily affected by both overall and individual geographic market conditions and apartment fundamentals and is 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. In addition, as discussed above under “Executive Overview - COVID-19 Pandemic” and elsewhere in this report, the COVID-19 pandemic continues to affect our business, and may continue to do so. See also Part I, Item 1A, “Risk Factors.” Discussion of our operating results for 2020 and comparison to 2019 can be found in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's Form 10-K filed with the SEC on February 25, 2021. A comparison of our operating results for 2021 and 2020 follows (dollars in thousands).

(1) Percent change is not meaningful.

Net income attributable to common stockholders increased $176,669,000, or 21.3%, to $1,004,299,000 in 2021 over 2020, primarily due to an increase in gains on consolidated and unconsolidated real estate dispositions in the current year, partially offset by a decrease in Same Store NOI and an increase in depreciation expense in the current year.

Table of Contents

NOI is considered by management 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 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. 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), corporate-level property management and other indirect operating expenses, 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 investments in unconsolidated entities, depreciation expense, income tax expense (benefit), casualty and impairment loss, gain on sale of communities, gain on other real estate transactions, net, net for-sale condominium activity and net operating income from real estate assets sold or held for sale.

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 fund cash needs. Residential NOI represents results attributable to the Company's apartment rental operations, including parking and other ancillary residential revenue. Reconciliations of NOI and Residential NOI for the years ended December 31, 2021 and 2020 to net income for each year are as follows (dollars in thousands):

For the year ended

Loss on extinguishment of debt, net 17,787 9,333

Income from investments in unconsolidated entities (38,585) (6,422)

The Residential NOI changes for 2021 as compared to 2020 consists of changes in the following categories (dollars in thousands):

Full Year

Development / Redevelopment 44,307

The decrease in our Residential Same Store NOI in 2021 is due to a decrease in rental revenue of $45,643,000, or 2.2% and an increase in property operating expenses of $20,300,000, or 3.2%, over 2020.

Rental and other income decreased $5,676,000, or 0.2%, in 2021 compared to the prior year primarily due to decreased rental rates, amortization of concessions at our Same Store communities and decreased rental income from dispositions, partially offset by additional rental income generated from development completions and development under construction and in lease-up and acquisitions, increased occupancy at our Same Store communities and a decrease in commercial uncollectible lease revenue.

As discussed elsewhere in this report, the COVID-19 pandemic, and direct and indirect related economic, regulatory and operating impacts, are likely to continue to adversely affect our rental revenue. Deteriorating financial conditions among our residents and commercial tenants, as well as regulations that limit our ability to evict residents and tenants, may continue to result in higher than normal uncollectible lease revenue. The pandemic may also continue to depress demand among consumers for our apartments for a variety of other reasons, including (i) if consumers decide to live in markets that are less costly than ours for one or more reasons, such as a decline in their income, remote working arrangements, or if they cannot freely access neighborhood amenities like restaurants, gyms and entertainment venues; (ii) that consumers who would otherwise rent may seek home ownership; and (iii) ongoing downward pressures on demand for certain types of housing (e.g., corporate apartment homes) or by certain consumers (e.g. students or consumers who require seasonal job-related demand such as in the entertainment industry).

Consolidated Communities—The weighted average number of occupied apartment homes for consolidated communities increased to 75,744 apartment homes for 2021, as compared to 73,724 homes for 2020. The weighted average monthly rental revenue per occupied apartment home decreased to $2,518 for 2021 as compared to $2,593 in 2020.

Same Store rental revenue decreased $35,671,000, or 1.7%, for the year ended December 31, 2021, compared to the prior year.

•Residential rental revenue decreased $45,643,000, or 2.2%, for the year ended December 31, 2021, compared to the prior year, including an offsetting decrease in uncollectible lease revenue of $2,227,000. See below for a table detailing the change in Same Store Residential rental revenue by market for the year ended December 31, 2021, including the attribution of the change between rental rates and Economic Occupancy (as defined below).

•As a result of the pandemic, we increased our use of residential concessions during 2021 and 2020 relative to concessions granted prior to 2020. Concessions for our Same Store communities granted in 2021 decreased from the prior year by $6,209,000 to $42,237,000. Concessions granted in 2021 remain at elevated levels relative to years prior to the COVID-19 pandemic. Concessions are amortized on a straight-line basis over the life of the respective leases (generally one year) and contributed to the overall decline in our Same Store rental revenue in 2021. The amortization of residential concessions for our Same Store communities increased by $38,190,000 in 2021 as compared to the prior year, and the remaining net unamortized balance of residential concessions as of December 31, 2021 and 2020 was $14,209,000 and $30,272,000, respectively.

•Commercial rental revenue increased $9,972,000, or 87.9%, for the year ended December 31, 2021, compared to the prior year due to a reduction in uncollectible lease revenue of $11,826,000, for the year ended December 31, 2021.

(1) Economic occupancy takes into account the fact that apartment homes of different sizes and locations within a community have different economic impacts on a community's gross revenue. 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 leased rates and vacant homes at market rents. Vacancy loss is determined by valuing vacant units at current market rents.

Direct property operating expenses, excluding property taxes increased $20,465,000, or 4.6%, in 2021 as compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities, as well as the timing of repairs and maintenance projects previously delayed due to the COVID-19 pandemic.

Same Store Residential direct property operating expenses, excluding property taxes, represents 99.9% of total Same Store operating expenses for the year ended December 31, 2021. Residential direct property operating expenses, excluding property taxes, increased $14,759,000, or 3.7%, in 2021 as compared to the prior year, primarily due to the timing of repairs and maintenance projects previously delayed due to the COVID-19 pandemic.

Property taxes increased $9,900,000, or 3.6%, in 2021 as compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities and increased assessments for the Company's stabilized portfolio, partially offset by decreased property taxes from dispositions.

Same Store Residential property taxes represents 98.8% of total Same Store property taxes for the year ended December 31, 2021. For Same Store, property taxes increased $5,541,000, or 2.3%, in 2021 as compared to the prior year, primarily due to increased assessments across the portfolio, increased rates in California and Metro NY/NJ and the expiration of certain property tax incentive programs in New York City in the current year, partially offset by successful appeals in 2021 in New York, California and Florida.

Expensed transaction, development and other pursuit costs, net of recoveries primarily reflect costs incurred for development pursuits not yet considered probable for development, as well as the abandonment of Development Rights and costs related to abandoned acquisition and disposition pursuits and any recoveries of costs incurred. These costs can be volatile, particularly in periods of increased acquisition pursuit activity, periods of economic downturn or when there is limited access to capital, and therefore 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 $9,168,000, or 73.9%, in 2021 as compared to the prior year. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City.

Interest expense, net increased $6,264,000, or 2.9%, in 2021 as compared to the prior year. This category includes interest costs offset by capitalized interest pertaining to development and redevelopment activity, amortization of premium/discount on debt, interest income and any mark to market impact from derivatives not in qualifying hedge relationships. The increase in 2021 was primarily due to a decrease in capitalized interest and an increase in the amount of unsecured indebtedness, partially offset by lower overall effective rates on unsecured indebtedness and a combination of a decrease in variable rates on, and amounts of, secured indebtedness.

Loss on extinguishment of debt, net reflects (i) prepayment penalties and (ii) the write-off of unamortized deferred financing costs, premiums/discounts and deferred hedging losses from our debt repurchase and retirement activity. The losses on extinguishment of debt, net of $17,787,000 and $9,333,000 in 2021 and 2020, respectively, were primarily due to the repayments of unsecured notes during each of those years.

Depreciation expense increased $51,265,000, or 7.2%, in 2021 as 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 (“G&A”) increased $9,268,000, or 15.4%, in 2021 as compared to the prior year, primarily due to legal settlement proceeds that were present in the prior year, coupled with increases in the current year of compensation related expenses, including executive transition costs, during the year ended December 31, 2021.

Casualty and impairment loss for the year ended December 31, 2021 of $3,119,000 consists of a $1,971,000 charge recognized for the damages across several communities in our East Coast markets related to severe storms and a $1,148,000 charge recognized for property and casualty damages resulting from a fire at an operating community.

Income from investments in unconsolidated entities increased $32,163,000 in 2021 as compared to the prior year, due to unrealized gains on property technology investments recognized in the current year and the gain on the sale of the final two communities in Archstone Multifamily Partners AC JV LP (the "AC JV"), partially offset by the gain on the sale of a community in Archstone Multifamily Partners AC LP (the "U.S. Fund") in the prior year.

Gain on sale of communities increased in 2021 as 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 and the market conditions in the local area. The gains of $602,235,000 and $340,444,000 in 2021 and 2020, respectively, were primarily due to the sale of nine wholly-owned operating communities in both 2021 and 2020.

Gain on other real estate transactions, net represents the impact from the sale of land parcels and other tangible and intangible real estate assets, and increased $1,657,000, or 376.6%, in 2021 due to the sale of residential entitlements.

Net for-sale condominium activity is a net expense of $977,000 for the year ended December 31, 2021 and a net gain of $2,551,000 for the year ended December 31, 2020, and is comprised of the net gain before taxes on the sale of condominiums at The Park Loggia less the associated marketing, operating and administrative costs. During the year ended December 31, 2021, we sold 53 residential condominiums at The Park Loggia, for gross proceeds of $135,458,000, resulting in a gain in accordance with GAAP of $3,110,000. During the year ended December 31, 2020, we sold 70 residential condominiums at The Park Loggia for gross proceeds of $216,372,000, resulting in a gain in accordance with GAAP of $8,213,000. In addition, we incurred $4,087,000 and $5,662,000 for the years ended December 31, 2021 and 2020, respectively, in marketing, operating and administrative costs.

Income tax (expense) benefit of $5,733,000 for the year ended December 31, 2021 was related to activity generated through our taxable REIT subsidiaries ("TRS") and was comprised primarily of tax expense for condominium sales at The Park Loggia and other ancillary real estate. Income tax benefit for the year ended December 31, 2020 was primarily due to tax losses as well as provisions of the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act").

Reconciliation of FFO and Core FFO

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 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 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. In calculating FFO, we exclude gains or losses related to dispositions of previously depreciated property and exclude real estate depreciation, which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates. 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. By further adjusting for items that are not considered by us to be part of our core business operations, Core FFO can help with the comparison of the core operating performance of the Company 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;

•gains or losses from early extinguishment of consolidated borrowings;

•development pursuit write-offs and expensed transaction costs, net of recoveries;

•third-party business interruption insurance proceeds and the related lost NOI that is covered by the expected third party business interruption insurance proceeds;

•property and casualty insurance proceeds and legal settlement activity;

•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;

•severance related costs;

•executive transition compensation costs;

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

•income taxes; and

•other non-core items.

FFO and Core FFO do not represent 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. In addition, FFO and Core FFO as calculated by other REITs may not be comparable to our calculations of FFO and Core FFO.

FFO and Core FFO also do not represent 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. Additionally, it is not necessarily indicative of cash available to fund cash needs. A presentation of GAAP-based cash flow metrics is included in our Consolidated Financial Statements included elsewhere in this report.

The following is a reconciliation of net income attributable to common stockholders to FFO attributable to common stockholders and to Core FFO attributable to common stockholders for the years ended December 31, 2021 and 2020 (dollars in thousands, except per share data).

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;

•debt service and principal payments either at maturity or opportunistically before maturity;

•normal recurring operating expenses and corporate overhead expenses; and

•investment in our operating platform, including strategic investments.

42

Table of Contents

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 cash in escrow of $543,788,000 at December 31, 2021, an increase of $230,256,000 from $313,532,000 at December 31, 2020. The following discussion relates to changes in cash, cash equivalents and cash in escrow due to operating, investing and financing activities, which are presented in our Consolidated Statements of Cash Flows included elsewhere in this report.

Operating Activities—Net cash provided by operating activities decreased to $1,203,170,000 in 2021 from $1,219,615,000 in 2020, primarily due to a decrease in NOI.

Investing Activities—Net cash used in investing activities totaled $624,053,000 in 2021. The net cash used was primarily due to:

•acquisition of seven operating communities for $771,692,000;

•investment of $654,861,000 in the development and redevelopment of communities; and

•capital expenditures of $153,235,000 for our operating communities and non-real estate assets.

These amounts were partially offset by:

•net proceeds from the disposition of nine operating communities and ancillary real estateof $850,230,000; and

•net proceeds from the sale of for-sale residential condominiums of $124,532,000.

Financing Activities—Net cash used in financing activities totaled $348,861,000 in 2021. The net cash used was primarily due to:

•payment of cash dividends in the amount of $888,344,000;

•repayment of unsecured notes in the amount of $462,147,000; and

•mortgage notes repayments and principal amortization payments in the amount of $109,562,000.

These amounts were partially offset by:

•proceeds from the issuance of unsecured notes in the amount of $1,098,643,000; and

•the issuance of common stock in the amount of $31,874,000 primarily through CEP V.

Variable Rate Unsecured Credit Facility

We have a $1,750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the “Credit Facility”) which matures in February 2024. The Credit Facility bears interest at varying levels based on (i) the London Interbank Offered Rate (“LIBOR”) 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.) and (ii) the rating levels issued for our unsecured notes. The current stated pricing for drawn borrowings is LIBOR plus 0.775% per annum (0.88% at January 31, 2022), assuming a one month borrowing rate. The annual facility fee for the Credit Facility remained at 0.125%, resulting in a fee of $2,188,000 annually based on the $1,750,000,000 facility size and based on our current credit rating.

43

Table of Contents

We had no borrowings outstanding under the Credit Facility and had $6,969,000 outstanding in letters of credit that reduced our borrowing capacity as of January 31, 2022. In addition, we had $39,581,000 outstanding in additional letters of credit unrelated to the Credit Facility as of January 31, 2022.

The phase-out of LIBOR and expected transition to SOFR as a benchmark interest rate will have uncertain and possibly adverse effects on our LIBOR borrowings. See Item 1A. “Risk Factors” for further discussion.

Financial Covenants

We are subject to financial covenants contained in the Credit Facility, Term Loans 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, 2021.

In addition, some of our secured borrowings include yield maintenance, defeasance, or prepayment penalty provisions, which would 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 secured borrowings are generally consistent with other similar types of debt instruments issued during the same time period in which our borrowings were secured.

Continuous Equity Offering Program

In May 2019, we commenced CEP V under which 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 engaged sales agents for CEP V who receive compensation of up to 1.5% of the gross sales price for shares sold. 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 2021 and through January 31, 2022, we sold 122,343 shares of common stock at an average sales price of $226.15 per share, for net proceeds of $27,253,000 under this program. In addition, at December 31, 2021, we were party to a forward contract under CEP V to sell 68,577 shares of common stock for approximate proceeds of $16,000,000 net of offering fees and discounts based on the initial forward price, with settlement of the forward contract to occur on one or more dates not later than December 31, 2022. The final proceeds will be determined on the date(s) of settlement after adjustments for our dividends and a daily interest factor. As of January 31, 2022, we had $705,961,000 remaining authorized for issuance under this program, after consideration of the forward contract.

Forward Interest Rate Swap Agreements

The following derivative activity occurred during the year ended December 31, 2021:

•We terminated $150,000,000 of forward interest rate swap agreements for which hedge accounting was ceased in 2020, receiving a payment of $6,962,000. We recognized $2,894,000 of these proceeds as a gain in 2020 and $2,654,000 of these proceeds as a gain during the year ended December 31, 2021, included in interest expense, net on the accompanying Consolidated Statements of Comprehensive Income.

•In conjunction with the issuance of our $700,000,000 2.05% unsecured notes due 2032 in September 2021, we settled $200,000,000 of forward interest rate swap agreements, entered into in 2021, designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a net payment of $2,211,000. We have deferred these amounts in accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets, and are recognizing the impact as a component of interest expense, net, over the term of the respective hedged debt.

•We entered into an additional $150,000,000 of new forward interest rate swap agreements executed to reduce the impact of variability in interest rates on a portion of our expected debt issuance activity in 2022.

At the maturity of the remaining outstanding swap agreements, we expect to cash settle the contracts and either pay or receive cash for the then current fair value. Assuming that we issue 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.

Stock Repurchase Program

In July 2020, our Board of Directors approved a new 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 "2020 Stock Repurchase Program"). Purchases of common stock under the 2020 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, market conditions and other corporate liquidity requirements and priorities. The 2020 Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. During 2021 and through January 31, 2022, we had no repurchases of shares under this program. As of January 31, 2022, we had $316,148,000 remaining authorized for purchase under this program.

Future Financing and Capital Needs—Debt Maturities and Material Obligations

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. 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, additional debt financing that is secured by mortgages on individual communities or groups of communities or borrowings 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, especially in light of the uncertain impacts of the COVID-19 pandemic on capital markets.

The following debt activity occurred during 2021:

•In January 2021, we repaid $27,795,000 principal amount of 5.37% fixed rate secured debt at par in advance of the April 2021 maturity date.

•In September 2021, we repaid $450,000,000 principal amount of our 2.95% unsecured notes in advance of the September 2022 scheduled maturity, recognizing a loss on debt extinguishment of $17,890,000, composed of a prepayment penalty of $12,147,000, and the non-cash write off of unamortized deferred hedging losses and unamortized deferred financing costs of $5,743,000.

•In September 2021, we issued $700,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement for proceeds net of underwriting fees of approximately $694,617,000, before

considering the impact of other offering costs. The notes mature in January 2032 and were issued at a 2.05% interest rate. The notes were issued under our green bond framework, and we have allocated or will allocate the net proceeds, in whole or in part, to one or more new or existing eligible green projects.

•In November 2021, we repaid an aggregate of $73,060,000 principal amount of fixed rate secured debt with a weighted average interest rate of 3.79% at par in advance of the November 2036 maturity date.

•In November 2021, 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 $396,976,000, before considering the impact of other offering costs. The notes mature in December 2028 and were issued at a 1.90% interest rate. The notes were issued under our green bond framework, and we have allocated or will allocate the net proceeds, in whole or in part, to one or more new or existing eligible green projects.

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 amounts outstanding related to communities classified as held for sale, for debt outstanding at December 31, 2021 and 2020 (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.

(4)Financed by variable rate debt, but interest rate is capped through an interest rate protection agreement.

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 $14,879,000 for 2022, $14,642,000 for 2023 and $372,346,000 thereafter.

Future Financing and Capital Needs—Portfolio and Capital Markets Activity

In 2022, we expect to meet our liquidity needs from one or more of a variety of internal and external sources, which may include (i) real estate dispositions, (ii) cash balances on hand as well as cash generated from our operating activities, (iii) borrowing capacity under our Credit Facility and (iv) secured and unsecured debt financings. Additional sources of liquidity in 2022 may include the issuance of common and preferred equity. 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.

Before beginning new construction or reconstruction activity in 2022, including activity related to communities owned by unconsolidated joint ventures, we plan to source sufficient capital to complete these undertakings, although we cannot assure you that we will be able to obtain such financing. In the event that financing cannot be obtained, we may have to abandon Development Rights, write off associated pre-development costs that were capitalized and/or forego reconstruction activity. In such instances, we will not realize the increased revenues and earnings that we expected from such Development Rights or reconstruction activity and significant losses could be incurred.

47

Table of Contents

From time to time we use joint ventures to hold or develop individual real estate assets. We generally employ joint ventures primarily to mitigate asset concentration or market risk and secondarily as a source of liquidity. We may also use joint ventures related to mixed-use land development opportunities and new markets where our partners bring development and operational expertise and/or experience to the venture. Each joint venture or partnership agreement has been individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture or partnership agreement. We cannot assure you that we will achieve our objectives through joint ventures.

In addition, we may invest, through mezzanine loans or other preferred equity investments, in multifamily development projects being undertaken by third parties. In these cases, we do not expect to acquire the underlying real estate but rather to earn a return on our investment (through interest or fixed rate preferred equity returns) and a return of the invested capital generally following completion of construction either on or before a set due date. As of January 31, 2022, we have not made any such investments but are pursuing opportunities.

In evaluating our allocation of capital within our markets, we sell assets that do not meet our long-term investment criteria or when capital and real estate markets allow us to realize a portion of the value created over our ownership periods and redeploy the proceeds from those sales to develop and redevelop communities. Because the proceeds from the sale of communities may not be immediately redeployed into revenue-generating assets that we develop, redevelop or acquire, the immediate effect of a sale of a community for a gain is to increase net income, but reduce future total revenues, total expenses and NOI until such time as the proceeds have been redeployed into revenue generating assets. We believe that the temporary absence of future cash flows from communities sold will not have a material impact on our ability to fund future liquidity and capital resource needs.

Investments

We invest in consolidated real estate entities, unconsolidated investments in real estate ventures and direct and indirect investments in technology and environmentally focused companies through investment management funds.

Consolidated Investments

During the year ended December 31, 2021, we acquired the following communities, which includes acquisitions marking our entry in the Texas and North Carolina expansion markets, containing 90,000 square feet of commercial space (dollars in thousands). See Note 5, "Investments," for further discussion.

Avalon Lakeside Flower Mound, TX 425 $ 117,000

Avalon Fort Lauderdale Fort Lauderdale, FL 243 $ 150,000

During the year ended December 31, 2021, we sold nine wholly-owned operating communities containing 2,404 apartment homes and 30,000 square feet of commercial space (dollars in thousands). See Note 6, "Real Estate Disposition Activities," for further discussion.

Unconsolidated Investments

During the year ended December 31, 2021, we had the following investment activity related to our unconsolidated real estate and technology and environmentally focused investments. See Note 5, "Investments," for further discussion.

•Archstone Multifamily Partners AC JV LP (the "AC JV") sold its final two communities, Avalon North Point and Avalon North Point Lofts, located in Cambridge, MA, for $325,000,000. Our proportionate share of the gain in accordance with GAAP was $23,305,000. In conjunction with the disposition of Avalon North Point, the AC JV repaid a $111,653,000 loan made by equity investors in the venture at par.

•Arts District Joint Venture was formed to develop, own, and operate AVA Arts District, an apartment community located in Los Angeles, CA, which is currently under construction and expected to contain 475 apartment homes and 56,000 square feet of commercial space when completed. We have a 25.0% ownership interest in the venture. As of December 31, 2021, excluding costs incurred in excess of equity in the underlying net assets of the venture, we have an equity investment of $30,436,000 in the venture. In addition to the equity contributions, the venture borrowed $11,581,000 under its $167,147,000 of the construction loan during the year ended December 31, 2021.

•Avalon Alderwood MF Member, LLC (“Avalon Alderwood Mall”) was formed to develop, own, and operate Avalon Alderwood Mall, an apartment community located in Lynnwood, WA, which is currently under construction and expected to contain 328 apartment homes when completed. We have a 50.0% ownership interest in the venture. As of December 31, 2021, we have an equity investment of $55,054,000 in the venture, which represents substantially all of our required equity contributions.

•We invested $17,277,000 in various property technology and environmentally focused companies directly and indirectly through investment management funds. We have $39,890,000 of outstanding equity commitments to these investment management funds, with the timing and amount for these commitments to be fulfilled dependent on if, and when, investment opportunities are identified by the respective funds. During the year ended December 31, 2021, we recognized income and unrealized gains of $15,908,000 related to these investments, included as a component of Income from investments in unconsolidated entities on the Consolidated Statements of Comprehensive Income.

Supplemental U.S. Federal Income Tax Considerations

The following discussion supplements and updates the disclosures under “Certain U.S. Federal Income Tax Considerations and Consequences of Your Investment" in the prospectus dated February 25, 2021 contained in our Registration Statement on Form S-3 filed with the SEC on February 25, 2021.
