*The Geographic Concentration of Our Communities in Certain Markets Could Have an Adverse Effect on Our Operations if a Particular Market is Adversely Impacted by Economic or Other Conditions.*For the six months ended June 30, 2026, approximately 75.0% of our total NOI was generated from communities located in Metropolitan D.C. (17.0%), Boston, MA (11.5%), Orange County, CA (11.2%), the San Francisco Bay Area, CA (9.3%), Dallas, TX (8.8%), New York, NY (6.1%), Tampa, FL (5.1%) and Seattle, WA (5.2%). As a result, if any one or more of these markets is adversely impacted by regional or local economic conditions or real estate market conditions, including new supply, such conditions may have a greater adverse impact on our results of operations than if our portfolio was more geographically diverse. In addition, if one or more of these markets is adversely affected by changes in regional or local regulations, including those related to rent control or stabilization, such regulations may have a greater adverse impact on our results of operations than if our portfolio was more geographically diverse.

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

Property Ownership Through Partnerships and Joint Ventures May Limit Our Ability to Act Exclusively in Our Interest. We have in the past and may in the future develop and/or acquire properties through partnerships and joint ventures, including those in which we own a preferred interest or debt, with other persons or entities when we believe circumstances warrant the use of such structures. As of June 30, 2026, we had active unconsolidated joint ventures and partnerships, including our preferred equity investments, with a total equity investment of $728.8 million. We have in the past, and could in the future, become engaged in a dispute with one or more of our partners which could adversely impact us. Moreover, our partners may have business, economic or other objectives that are inconsistent with our objectives, including objectives that relate to the appropriate timing and terms of any sale or refinancing of a property. In some instances, our partners may have competing interests in our markets that could create conflicts of interest. Also, our partners have in the past failed, and may in the future fail to make capital contributions when due and our partners or the project may otherwise not act or perform as expected, or the property may not be operated in the manner in which we would operate it, any of which may require us to contribute additional capital, acquire our partner’s interest or other property, or take other actions that may negatively impact the project or our return. In addition, we may be responsible to our partners for indemnifiable losses. In general, we and our partners may each have the right to trigger a buy-sell or other similar arrangement, which arrangement or other factors could cause us to sell our interest, or acquire our partner’s interest or other property, at a time when we otherwise would not have initiated such a transaction and may result in the valuation of our interest in the partnership or joint venture (if we are the seller) or of the other partner’s interest in the partnership or joint venture (if we are the buyer) at levels which may not be representative of the valuation that would result from an arm’s length marketing process and could cause us to recognize unanticipated capital gains or losses or the loss of fee income.

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

*The Adoption of, or Changes to, Rent Control, Rent Stabilization, Eviction, Tenants’ Rights and Similar Laws and Regulations in Our Markets Could Have an Adverse Effect on Our Results of Operations and Property Values.*Various state and local governments as well as the federal government have enacted and may continue to enact rent control, rent stabilization, eviction, tenants’ rights, allowable fees, and other matters, as well as any lawsuits against us arising from such laws and regulations, may limit our ability to charge market rents, increase rents, evict delinquent tenants or charge fees, or recover increases in our operating expenses, which could have an adverse effect on our results of operations and the value of our properties. These laws, regulations and policies may apply prospectively or retroactively. For example, in 2023, Montgomery County, Maryland enacted rent control that currently impacts a portion of our portfolio in that market. In 2024, the State of New York passed the Good Cause Eviction Law, which established rent limits on certain market-rate apartments. In the City of New York, the new administration was successful in enacting a freeze on rent increases for covered properties. Although our properties currently have minimal exposure to the city’s allowable annual rent increases, such a freeze, or other measures that seek to increase affordability, would in turn reduce our property values. In 2024, the City of Salinas, California passed a rent stabilization ordinance that impacted all our properties within the city. In 2025, the State of Washington enacted statewide rent control, which initially impacts a portion of our properties within the state. In some cases, the increases in rents allowed by such regulations may not offset increases in expenses, whether such increases in expenses are due to inflation or otherwise. We have seen a recent increase in governments enacting or considering, or being urged to consider, such laws and regulations. Federal, state and local governments or courts also have made, and may make in the future, changes to laws related to allowable fees and rents, eviction and other tenants’ rights laws and regulations (including changes that apply retroactively) that could adversely impact our results of operations and the value of our properties. In addition, the increases in regulations applicable to our business in general may increase our costs of compliance and could have an adverse effect on our financial performance.

Compliance with or Changes in Real Estate Tax and Other Laws and Regulations Could Adversely Affect Our Funds from Operations and Our Ability to Make Distributions to Stockholders. We are subject to federal, state and local laws, regulations, rules and ordinances at locations where we operate regarding a wide variety of matters that could affect, directly or indirectly, our operations. Generally, we do not directly pass through costs resulting from compliance with or changes in real estate tax laws to residential property tenants. We also do not generally pass through increases in income, service or other taxes to tenants under leases. These costs may adversely affect net operating income and the ability to make distributions to stockholders. Similarly, compliance with or changes in (i) laws increasing the potential liability for environmental conditions existing on properties or the restrictions on discharges or other conditions, (ii) laws and regulations regulating housing, such as the Americans with Disabilities Act and the Fair Housing Amendments Act of 1988, or (iii) employment related laws, among others, may result in significant unanticipated expenditures, which could adversely affect our financial condition and results of operations. In addition, changes in federal and state legislation and regulation on climate change may result in increased capital expenditures to improve the energy efficiency of our existing communities and also may require us to spend more on our new development communities without a corresponding increase in revenue. In addition, existing laws could be interpreted in a manner that restricts our ability to use systems that we currently use in our operations and we may face litigation or regulatory risk in connection with such laws. Future compliance with new laws of general applicability, laws applicable to companies in our industry, or laws applicable to public companies generally could increase our costs, including compliance penalties, and could have an adverse effect on our financial performance.

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

Third-Party Expectations Relating to Environmental, Social and Governance Factors May Impose Additional Costs and Expose Us to New Risks. There is a focus from certain investors, tenants, employees, and other stakeholders concerning corporate responsibility, specifically related to environmental, social and governance factors. In addition, there has been increased focus on such matters by various regulatory authorities, including the SEC and the state of California and other states or jurisdictions, and the activities and expense required to comply with new laws, regulations or standards may be significant. In addition, the standards or expectations of various stakeholders or regulators may differ from each other and it may not be possible to comply with all of such standards or expectations. Some investors may use these factors to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our policies relating to corporate responsibility are inadequate. Third-party providers of corporate responsibility ratings and reports on companies have increased in number, resulting in varied and in some cases inconsistent standards. In addition, the criteria by which companies’ corporate responsibility practices are assessed and the regulations applicable thereto are evolving, which could result in greater expectations of us and cause us to undertake costly initiatives or activities to satisfy such new criteria or regulations. Further, if we elect not to or are unable to satisfy such new criteria or do not meet the criteria of a specific third-party provider or investor, some investors may conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational damage in the event that our corporate responsibility procedures or standards do not meet the standards set by various constituencies.

In addition, the standards or expectations of various stakeholders or regulators may differ from each other and it may not be possible to comply with all of such standards or expectations. Some investors may use these factors to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our policies relating to corporate responsibility are inadequate. Third-party providers of corporate responsibility ratings and reports on companies have increased in number, resulting in varied and in some cases inconsistent standards. In addition,

In addition, we have communicated certain initiatives and goals regarding environmental, social and governance matters, and we may in the future communicate revised or additional initiatives or goals. We could fail, or be perceived to fail, in our achievement of such initiatives or goals, or we could be criticized for the scope of such initiatives or goals. In addition, certain locations have enacted, and others may in the future enact, sustainability regulations pertaining to buildings, including existing buildings.

the criteria by which companies’ corporate responsibility practices are assessed and the regulations applicable thereto are evolving, which could result in greater expectations of us and cause us to undertake costly initiatives or activities to satisfy such new criteria or regulations. Further, if we elect not to or are unable to satisfy such new criteria or do not meet the criteria of a specific third-party provider or investor, some investors may conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational damage in the event that our corporate responsibility procedures or standards do not meet the standards set by various constituencies. Furthermore, if our competitors’ corporate responsibility performance is perceived to be greater than ours, potential or current investors may elect to invest in our competitors instead. In addition, we have communicated certain initiatives and goals regarding environmental, social and governance matters, and we may in the future communicate revised or additional initiatives or goals.

Changing Interest Rates Could Increase Interest Costs and Adversely Affect Our Cash Flows and the Market Price of Our Common Stock. We currently have, and expect to incur in the future, interest-bearing debt, including unsecured commercial paper, at rates that vary with market interest rates. As of June 30, 2026, we had approximately $693.0 million of variable rate indebtedness outstanding, which constitutes approximately 11.9% of total outstanding indebtedness as of such date, and we have from time to time experienced increases in the interest rates on such indebtedness, which has increased our interest expense and adversely impacted our results of operations and cash flows. In addition, as a result of higher interest rates, the costs of hedging transactions have increased significantly and may continue to increase. Continued increases in interest rates would further increase our interest expenses and increase the costs of refinancing existing indebtedness and of issuing new debt, including unsecured commercial paper. The effect of any prolonged interest rate increases could negatively impact our ability to service our indebtedness, make distributions to security holders, make acquisitions and develop properties.

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

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

Limitations on Share Ownership and Limitations on the Ability of Our Stockholders to Effect a Change in Control of Our Company Restrict the Transferability of Our Stock and May Prevent Takeovers That are Beneficial to Our Stockholders. One of the requirements for maintenance of our qualification as a REIT for U.S. federal income tax purposes is that no more than 50% in value of our outstanding capital stock may be owned by five or fewer individuals, including entities specified in the Code, during the last half of any taxable year. Our charter contains ownership and transfer restrictions relating to our stock primarily to assist us in complying with this and other REIT ownership requirements; however, the restrictions may have the effect of preventing a change of control which does not threaten our REIT status. These restrictions include a provision that generally limits ownership by any person of more than 9.9% of the value of our outstanding equity stock, unless our board of directors exempts the person from such ownership limitation, provided that any such exemption shall not allow the person to exceed 13% of the value of our outstanding equity stock. Absent such an exemption from our board of directors, the transfer of our stock to any person in excess of the applicable ownership limit, or any transfer of shares of such stock in violation of the

These provisions of our charter may have the effect of delaying, deferring or preventing someone from taking control of us, even though a change of control might involve a premium price for our stockholders or might otherwise be in our stockholders’ best interests.
