TABLE OF CONTENTS

Explanatory Note

This report combines the Annual Reports on Form 10-K for the year ended December 31, 2025 of Mid-America Apartment Communities, Inc., a Tennessee corporation, and Mid-America Apartments, L.P., a Tennessee limited partnership, of which Mid-America Apartment Communities, Inc. is the sole general partner. Mid-America Apartment Communities, Inc. and its 97.5% owned subsidiary, Mid-America Apartments, L.P., are both required to file annual reports under the Securities Exchange Act of 1934, as amended.

Unless the context otherwise requires, all references in this Annual Report on Form 10-K to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries. Unless the context otherwise requires, all references in this report to “we,” “us,” “our,” or the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P. Unless the context otherwise requires, all references in this report to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P. together with its consolidated subsidiaries. “Common stock” refers to the common stock of MAA, “preferred stock” refers to the preferred stock of MAA, and “shareholders” refers to the holders of shares of MAA’s common stock or preferred stock, as applicable. The common units of limited partnership interest in the Operating Partnership are referred to as “OP Units” and the holders of the OP Units are referred to as “common unitholders.”

As of December 31, 2025, MAA owned 116,878,077 OP Units (97.5% of the total number of OP Units). MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership’s sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership.

We believe combining the Annual Reports on Form 10-K of MAA and the Operating Partnership, including the notes to the consolidated financial statements, into this report results in the following benefits:

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership. We believe it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company. MAA and the Operating Partnership are structured as an umbrella partnership REIT, or UPREIT. MAA’s interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA’s percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners. MAA’s only material asset is its ownership of limited partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership from time to time. The Operating Partnership holds, directly or indirectly, all of the Company’s real estate assets. Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, direct or indirect incurrence of indebtedness and issuance of OP Units.

The presentation of MAA’s shareholders’ equity and the Operating Partnership’s capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA’s shareholders’ equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interests, treasury shares, accumulated other comprehensive income or loss and redeemable common stock. The Operating Partnership’s capital may include common capital and preferred capital of the general partner (MAA), limited partners’ common capital and preferred capital, noncontrolling interests, accumulated other comprehensive income or loss and redeemable common units. Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA’s common stock on the New York Stock Exchange, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed.

In order to highlight the material differences between MAA and the Operating Partnership, this Annual Report on Form 10-K includes sections that separately present and discuss areas that are materially different between MAA and the Operating Partnership, including:

In the sections that combine disclosures for MAA and the Operating Partnership, this Annual Report on Form 10-K refers to actions or holdings as being actions or holdings of the Company. Although the Operating Partnership (directly or indirectly through one of its subsidiaries) is generally the entity that enters into contracts, holds assets and issues debt, management believes this presentation is appropriate for the reasons set forth above and because we operate the business through the Operating Partnership. MAA, the Operating Partnership and its subsidiaries operate as one consolidated business, but MAA, the Operating Partnership and each of its subsidiaries are separate, distinct legal entities.

PART I

Item 1. Business.

Overview

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. We own, operate, acquire and selectively develop apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the U.S. As of December 31, 2025, we maintained full or partial ownership of apartment communities, including communities currently in development, across 16 states and the District of Columbia, summarized as follows:

Our business is conducted principally through the Operating Partnership. MAA is the sole general partner of the Operating Partnership, holding 116,878,077 OP Units, comprising a 97.5% partnership interest in the Operating Partnership as of December 31, 2025. MAA and MAALP were formed in Tennessee in 1993.

Business Objectives

Our primary business objectives are to generate a sustainable, stable and increasing cash flow that will fund our dividends and distributions through all parts of the real estate investment cycle. To achieve these objectives, we intend to continue to pursue the following goals and strategies:

Operations

Our goal is to generate return on investment collectively and in each apartment community by increasing revenues, controlling operating expenses, maintaining high occupancy levels and reinvesting in the income producing capacity of each apartment community as appropriate. The steps taken to meet these objectives include:

We believe in leveraging the strength of our enterprise as a foundation for our operating structure, which capitalizes on local management with specific market knowledge and accountability. Senior management, along with certain centralized asset management functions, are proactively involved in supporting and optimizing property operations and reviewing property management performance through extensive reporting processes and on-site visits. Our significant platform allows us to take advantage of technology that makes information sharing easier on a real-time basis, allows for operating efficiencies and continued expense control, and provides for various expanded revenue management practices to improve the support provided to on-site property operations.

Investment in technology continues to drive operating efficiencies in our business and helps us to better meet the changing needs of our residents. Our residents have the ability to conduct business with us 24 hours a day, seven days a week and complete online leasing applications, leases and renewals through our web-based resident portal. Interacting with our residents through such technology has allowed us to improve resident satisfaction ratings and increase the efficiency of our operating teams. We continue to invest in technology to enable potential residents to examine their future homes both online (virtual touring) or by self-guided tour (self-touring) in addition to the more traditional guided tour.

Acquisitions and Development

Our external growth strategy is to acquire existing apartment communities, utilize our internal development team to develop our own apartment communities and partner with select developers to develop apartment communities that we will own completely after stabilization, which we refer to as a pre-purchase transaction. Acquisitions and development, along with dispositions, help us achieve and maintain our desired product mix, geographic diversification and asset allocation. Portfolio growth allows for maximizing the efficiency of the existing management and overhead structure. We have extensive experience in the acquisition and development of apartment communities. We will continue to evaluate opportunities that arise, and we will utilize this strategy to increase our number of apartment communities in strong and growing markets.

We acquired the following properties during the year ended December 31, 2025:

Development activities may be conducted through wholly-owned entities or through joint ventures with our pre-purchase transaction partners. Typically, fixed price construction contracts are signed with unrelated parties to minimize the risk of increases in construction costs. We may also engage in limited expansion development opportunities on existing communities in which we typically serve as the developer. During the year ended December 31, 2025, we incurred $272.0 million in development costs and completed one development project. For information regarding our development costs, see Note 1 (Organization and Summary of Significant Accounting Policies – Development Costs) to the consolidated financial statements included in this Annual Report on Form 10-K.

The following multifamily projects were under development as of December 31, 2025 (dollars in thousands):

The following multifamily development project was completed during the year ended December 31, 2025 (dollars in thousands):

Dispositions

We sell apartment communities and other assets that no longer meet our long-term strategy or when market conditions are favorable, and we redeploy the proceeds from those sales to acquire, develop and redevelop additional apartment communities and rebalance our portfolio across or within geographic regions. Dispositions also allow us to realize a portion of the value created through our investments and provide additional liquidity. We are then able to redeploy the net proceeds from our dispositions in lieu of raising additional equity or debt capital. In deciding to sell an apartment community, we consider current market conditions and generally solicit competing bids from unrelated parties for these individual properties. We then consider the sales price and other key terms of each proposal. We also consider portfolio dispositions when such a structure is useful to maximize proceeds and efficiency of execution. During the year ended December 31, 2025, we disposed of two multifamily communities totaling 576 units.

Property Redevelopment and Repositioning Activity

We focus on both interior unit upgrades and property amenity and common area upgrades above and beyond routine capital upkeep on our apartment communities that we believe have the ability to support additional rent growth. During the year ended December 31, 2025, we renovated the kitchens and bathrooms of 5,995 apartment units at an average cost of $6,080 per apartment unit, achieving average rental rate increases of 7.0% above the normal market rate for similar but non-renovated apartment units.

We have installed smart home technology (unit entry locks, mobile control of lights and thermostat and leak monitoring) at many of our apartment communities in order to provide additional resident value and increase rent growth. As of December 31, 2025, we had completed installation of Smart Home technology in over 96,000 units across our apartment community portfolio providing an increase in average effective rent per unit of approximately $25 per month since the initiative began during the first quarter of 2019. For a definition of average effective rent per unit, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Trends” in this Annual Report on Form 10-K.

Separately, we continued our WiFi retrofit program at select apartment communities, as well as our property repositioning program to upgrade and reposition the amenity and common areas at select apartment communities for higher and above market rent growth after projects are completed and units are fully repriced. We spent $7.8 million on the WiFi retrofit program and $12.1 million on the property repositioning program during the year ended December 31, 2025.

Portfolio Strategy

Our goal is to maintain a diversified, balanced portfolio that we believe provides the optimal path to maximizing operating performance over the full economic cycle. Maintaining a diverse portfolio includes:

We believe a diverse portfolio performs well during economic up cycles and weathers economic down cycles better than a more homogenous portfolio.

Human Capital

As of December 31, 2025, we employed 2,507 associates. Our associates’ time, energy, creativity and passion are essential to our continued success as a company. With respect to our workforce, we focus on inclusion, providing market-competitive pay and benefits to support our associates’ well-being, encouraging our associates’ growth and development, fostering associate engagement and protecting our associates’ health and safety.

We respect the privilege of providing value to those whose lives we touch. We call this outlook our “Brighter View.” To achieve these objectives, we use our Core Values to guide the way we interact with each other and conduct business by:

These values inform our human capital management approach, including how we recruit, develop and retain our workforce and support an environment where associates feel included and respected.

We maintain policies and practices intended to support a respectful and inclusive workplace and to promote equal employment opportunity and fair treatment. These practices are integrated into and support ongoing operations.

Our Inclusion & Belonging Committee is comprised of associates from across the organization and is intended to support ongoing review of policies, practices, and educational efforts related to inclusion. The committee works collaboratively with our Chief Executive Officer and other members of our executive team to help ensure employment related policies, practices, and educational efforts are consistently applied and in a manner intended to be free from discrimination and bias.

We recruit from a diverse range of sources and talent pools including advertising open positions on job boards that target a broad range of candidate populations. As of December 31, 2025, ethnic/cultural minorities represented approximately 55% of our workforce, 44% of our collective corporate, regional and property leadership positions and 49% of our associates promoted during the year ended December 31, 2025. Also, as of December 31, 2025, females represented approximately 45% of our workforce, 56% of our collective corporate, regional and property leadership positions and 50% of our associates promoted during the year ended December 31, 2025.

We take a comprehensive approach to supporting our associates’ physical and emotional health as well as their financial and professional well-being. Our associates are eligible for many benefit plans and programs for which we pay part or all of the cost, such as medical, dental and vision insurance, life and disability insurance, various wellness programs and an employee assistance program. In addition, we offer several supplemental and voluntary benefit plans, paid sick leave, paid vacation and other paid time off benefits to support our associates’ overall well-being. We strive to maintain an equitable compensation program for performance, designed to reward competitive levels of compensation based on employee contributions, performance and qualifications. We offer a 401(k) savings plan with an employer match as well as educational support for savings strategies. We also offer discounted rent to associates, parental leave and financial assistance with adoption expenses as well as grant up to three scholarships for associates’ dependents each year. Our training and development programs are designed to provide continuous learning for associates in the flow of their workday. Additionally, we encourage and provide financial assistance to our eligible associates to seek education and certification outside of the company through both apartment associations and accredited educational institutions. We encourage our associates to “embrace opportunities” including developing skills and knowledge needed for increased responsibilities as they promote within the company.

We place an emphasis on communication in an effort to ensure associates feel informed and connected as an organization. We utilize a variety of communication channels to provide associates with timely information that is relevant to their role in the company, to company-wide initiatives and to their professional interests. We also believe the best way to gain in-depth insight into our associates’ outlook on their experience at MAA is to provide regular, frequent, and trusted opportunities to safely share feedback. From there, we are able to develop and continuously improve our work environment to enhance job satisfaction. We regularly conduct surveys with all associates to measure associate engagement and capture topical feedback to guide current programs, projects and progress. We are also driven to prove that we are listening to feedback given, and that real action and improvements are executed as a result. Lastly, we conduct an annual review process to provide an opportunity for each associate to build mutual understanding with leadership, gain self-discovery and learn about possible avenues for growth. We encourage a work environment where ideas, problems and solutions can be discussed with immediate managers and other management personnel.

Capital Structure

We use a combination of debt and equity sources to fund our business objectives. We focus on maintaining access, flexibility and low costs, which we believe allows us to proactively support normal business operations and source potential investment opportunities in the marketplace. We structure our debt maturities to avoid disproportionate exposure in any given year. Our primary debt financing strategy is to access the unsecured debt markets to provide our debt capital needs, but we also maintain a limited amount of secured debt and maintain our access to both the secured and unsecured debt markets for maximum flexibility. We also believe that we have significant access to the equity capital markets.

We intend to target our total debt, net of cash held, to a range of approximately 30% to 36% of our adjusted total assets (as defined in the covenants for the unsecured senior notes issued by MAALP). Our charter and bylaws do not limit our debt levels and our Board of Directors can modify this policy at any time. We may issue new equity to maintain our debt within the target range. Covenants for our unsecured senior notes limit our total debt to 60% or less of our adjusted total assets. As of December 31, 2025, our total debt was 30.2% of our adjusted total assets.

We intend to target the ratio of our net debt to Adjusted EBITDAre to a range of 4.5x to 5.5x. We monitor our debt levels to a ratio of net debt to Adjusted EBITDAre in order to maintain our investment grade credit ratings. We believe this is an important factor in the management of our debt levels to maintain an optimal capital structure, and it is also considered in the assignment of our credit ratings. Adjusted EBITDAre is measured on a trailing twelve-month basis. As of December 31, 2025, our net debt to Adjusted EBITDAre ratio was 4.3x. For additional information on net debt and Adjusted EBITDAre, including reconciliations of the most directly comparable U.S. generally accepted accounting principles, or GAAP, measures to both net debt and Adjusted EBITDAre, see “Management’s Discussion and Analysis of Financial Condition and Results of Operation - Non-GAAP Financial Measures - Net Debt, EBITDA, EBITDAre, and Adjusted EBITDAre” in this Annual Report on Form 10-K.

We continuously review opportunities for lowering our cost of capital. We plan to continue using unsecured debt to take advantage of the lower cost of capital and flexibility provided by these markets. We will evaluate opportunities to repurchase shares when we believe that our share price is significantly below our net present value. We also look for opportunities where we can acquire or develop apartment communities, selectively funded or partially funded by sales of equity securities, when appropriate opportunities arise. We focus on improving the net present value of our investments by generating cash flow from our portfolio of assets above the estimated total cost of debt and equity capital. We routinely make new investments when we believe it will be accretive to shareholder value over the life of the investments.

Competition and Market Demand

Our apartment communities are located in areas that include other apartment communities. Occupancy and rental rates are affected by the number of competitive apartment communities as well as demand for housing in a particular area. The owners of competing apartment communities may have greater resources than us, and the managers of these apartment communities may have more experience than our management. Moreover, single-family rental housing, manufactured housing, condominiums and the new and existing home markets provide housing alternatives to potential residents of apartment communities. Competition for new residents is generally intense across all of our markets. Some competing apartment communities offer features that our apartment communities do not have or may be deemed to be in a more desirable location within the market. Competing apartment communities can use concessions or lower rents to obtain temporary competitive advantages. Also, some competing apartment communities are newer than our apartment communities, may have different amenities or otherwise be more attractive to a prospective resident. The competitive position of each apartment community is different depending upon many factors including submarket supply and demand. In addition, other real estate investors compete with us to acquire existing properties and to develop new properties. These competitors include insurance companies, pension and investment funds, public and private real estate companies, investment companies and other public and private apartment REITs, some of which may have greater resources, greater ability to utilize leverage or lower capital costs than we do.

We believe, however, that we are generally well-positioned to compete effectively for residents and acquisition and development opportunities. We believe our competitive advantages include:

Moving forward, we plan to continue our focus on optimizing lease expiration management, current and prospective resident engagement, expense control and resident retention efforts and also to align employee incentive plans with our performance. We also plan to continue to make capital improvements to both our apartment communities and individual units on a regular basis to maintain a competitive position. We believe this plan of operation, coupled with the portfolio’s strengths in targeting residents across a geographically diverse platform, should position us for continued operational growth.

For information regarding trends in market demand, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Trends” in this Annual Report on Form 10-K.

Environmental Matters

As a part of our standard apartment community acquisition and development processes, we generally obtain environmental studies of the sites from outside environmental engineering firms. The purpose of these studies is to identify potential sources of contamination at the site and to assess the status of environmental regulatory compliance. These studies generally include historical reviews of the site, reviews of certain public records, preliminary investigations of the site and surrounding properties, inspection for the presence of asbestos, poly-chlorinated biphenyls and underground storage tanks followed by the preparation and issuance of written reports. Depending on the results of these studies, more invasive procedures, such as soil sampling or ground water analysis, may be performed to investigate potential sources of contamination. These studies must be satisfactorily completed before we take ownership of an acquisition or development property; however, no assurance can be given that the studies or additional documents reviewed identify all significant environmental risks. See “Risk Factors – Environmental problems are possible and can be costly” and “Risk Factors – Compliance or failure to comply with laws and regulations could have an adverse effect on our operations and the values of our properties” in this Annual Report on Form 10-K.

Should any potential environmental risks or conditions be discovered during our due diligence process, the potential costs of remediation will be assessed carefully and factored into the cost of acquisition, assuming the identified risks and factors are deemed to be manageable and within reason. As of the date of this Annual Report on Form 10-K, we are not aware of any existing conditions that we believe would be considered a material environmental liability. Nevertheless, it is possible that the studies do not reveal all environmental risks or that there are material environmental liabilities of which we are not aware. Moreover, no assurance can be given concerning future laws, ordinances or regulations, or the potential introduction of hazardous or toxic substances by neighboring properties or residents.

Government Regulations

We must own, operate, manage, acquire, develop and redevelop our properties in compliance with numerous federal, state and local laws and regulations, some of which may conflict with one another or are subject to limited judicial or regulatory interpretations. These laws and regulations include landlord-tenant laws, employment laws, antitrust and other competition laws, laws benefiting disabled persons, privacy laws, tax laws, environmental laws, zoning laws, building codes and other laws regulating housing or that are generally applicable to our business and operations. Noncompliance with laws and regulations could expose us to liability, such as the imposition of fines by the government or the award of damages to private litigants, and could require us to make significant unanticipated expenditures, such as making modifications to our existing apartment communities or increasing construction costs for development communities. Compliance with the various laws and regulations we are subject to did not have a material effect on our capital expenditures, results of operations and competitive position for the year ended December 31, 2025 as compared to prior periods.

For additional information, see “Risk Factors – Environmental problems are possible and can be costly” and “Risk Factors – Compliance or failure to comply with laws and regulations could have an adverse effect on our operations and the values of our properties” in this Annual Report on Form 10-K.

Qualification as a Real Estate Investment Trust

MAA has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code. To continue to qualify as a REIT, MAA must continue to meet certain tests which, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets and that we distribute at least 90% of our REIT taxable income (other than our net capital gains) to our shareholders annually. If MAA maintains its qualification as a REIT, MAA generally will not be subject to U.S. federal income taxes at the corporate level on its net income to the extent it distributes such net income to its shareholders annually. Even if MAA continues to qualify as a REIT, it will continue to be subject to certain federal, state and local taxes on its income and its property. For the year ended December 31, 2025, MAA paid total distributions of $6.06 per share of common stock to its shareholders, which was above the 90% REIT distribution requirement.

Website Access to Our Reports

MAA and the Operating Partnership file combined periodic reports with the SEC.

Item 1A. Risk Factors.

In addition to the other information contained in this Annual Report on Form 10-K, we have identified the following risks and uncertainties that may have a material adverse effect on our business prospects, financial condition or results of operations. Investors should carefully consider the risks described below before making an investment decision. Our business faces significant risks and the risks described below may not be the only risks we face. Additional risks that are not presently known to us, that we currently believe are immaterial or that could apply generically to any company may also significantly impact our business operations. If any of these risks occur, our business prospects, financial condition or results of operations could suffer, the market price of our stock and the trading price of our debt securities could decline and you could lose all or part of your investment in our stock or debt securities.

Risks Related to Our Real Estate Investments and Our Operations

Unfavorable market and economic conditions could adversely affect occupancy levels, rental revenues and the value of our properties.

General economic conditions in the U.S. have fluctuated in recent years, and concerns persist regarding negative macroeconomic conditions, such as inflation and the labor market. Unfavorable market and economic conditions may significantly affect our occupancy levels, our rental rates and collections, the value of our properties and our ability to acquire or dispose of properties on economically favorable terms. Our ability to lease our properties at favorable rates is adversely affected by the increase in supply in the multifamily and other rental markets and is dependent upon the overall level in the economy, which is adversely affected by, among other things, job losses and unemployment levels, personal debt levels, a downturn in the housing market, stock market volatility, inflationary conditions and uncertainty about the future. Some of our major expenses generally do not decline when rents decline. We would expect that declines in our occupancy levels, rental revenues and/or the values of our properties would cause us to have less cash available to make payments on our debt and to make distributions, which could adversely affect our financial condition or the market value of our securities. Factors that may affect our occupancy levels, our rental revenues and/or the value of our properties include the following, among others:

Failure to generate sufficient cash flow could limit our ability to make payments on our debt and to make distributions.

Our ability to make payments on our debt and to make distributions depends on our ability to generate cash flow in excess of operating costs and capital expenditure requirements and/or to have access to the markets for debt and equity financing. Our funds from operations may be insufficient because of factors that are beyond our control. Such factors could include:

At times, we have relied on external funding sources to fully fund the payment of distributions to shareholders and our capital investment program, including our property developments. While we have sufficient liquidity to permit distributions at current rates through additional borrowings, if necessary, any significant and sustained deterioration in operations could result in our financial resources being insufficient to make payments on our debt and to make distributions at the current rate, in which event we would be required to reduce the distribution rate. Any decline in our funds from operations could adversely affect our ability to make distributions or to meet our loan covenants and could have a material adverse effect on our stock price or the trading price of our debt securities.

We are dependent on a concentration of our investments in a single asset class, making our results of operations more vulnerable to a downturn or slowdown in the multifamily sector or other economic factors.

As of December 31, 2025, substantially all of our investments are concentrated in the multifamily sector. As a result, we will be subject to risks inherent in investments in a single type of property. A downturn or slowdown in the demand for multifamily housing will have more pronounced effects on our results of operations and on the value of our assets than if we had diversified our investments into more than one asset class.

Our operations are concentrated in the Southeast, Southwest and Mid-Atlantic regions of the U.S.; we are subject to general economic conditions in the regions in which we operate.

As of December 31, 2025, approximately 41.2% of our portfolio (based on the number of completed apartment units) was located in our top five markets: Atlanta, Georgia; Dallas, Texas; Austin, Texas; Charlotte, North Carolina; and Orlando, Florida. In addition, our overall operations are concentrated in the Southeast, Southwest and Mid-Atlantic regions of the U.S. Our performance could be adversely affected by economic conditions in, and other factors relating to, these geographic areas, including supply and demand for apartments in these areas, zoning and other regulatory conditions and competition from other communities and alternative housing options. In particular, our performance is disproportionately influenced by job growth and unemployment. To the extent the economic conditions, job growth and unemployment in any of these markets deteriorate or any of these areas experiences natural disasters, the value of our portfolio, our results of operations and our ability to make payments on our debt and to make distributions could be adversely affected.

Substantial competition may adversely affect our revenues and limit our acquisition and development opportunities.

There are numerous alternative housing options within the market area of each of our communities that compete with us for residents, including other apartment communities, condominiums and single-family homes. Competitive housing in a particular area, particularly new supply (and especially during lease up efforts), could adversely affect our ability to retain residents, rent our apartments and increase or maintain rents, which could materially adversely affect our results of operations and financial condition. Similarly, some of our competitors may have loan covenants or fund requirements that encourage decisions on occupancy targets or rental rates that vary from decisions based on market conditions, which could require us to react in ways that may negatively affect our performance.

We also face competition from other businesses for acquisition and development opportunities. The activities of these competitors could cause us to pay higher prices for new properties than we otherwise would have paid or may prevent us from purchasing desired properties at all, which could have a material adverse effect on us and our ability to make payments on our debt and to make distributions.

Failure to succeed in new markets may have adverse consequences on our performance.

We may make acquisitions or pursue developments outside of our existing market areas if appropriate opportunities arise. Our historical experience in our existing markets does not ensure that we will be able to operate successfully in new markets, should we choose to enter them. We may be exposed to a variety of risks if we choose to enter new markets, including an inability to accurately evaluate local market conditions and local economies, an inability to identify appropriate acquisition or development opportunities, an inability to hire and retain key personnel and a lack of familiarity with local governmental and permitting procedures. In addition, we may abandon opportunities to enter new markets that we have begun to explore for any reason and may, as a result, fail to recover expenses already incurred.

Environmental problems are possible and can be costly.

Under various federal, state and local laws, ordinances and regulations, a current or previous owner or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances in, on, around or under such property. Such laws often impose such liability without regard to whether the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. The presence of, or failure to properly remediate, hazardous or toxic substances or petroleum product releases may adversely affect the owner’s or operator’s ability to sell or rent the affected property or to borrow using the property as collateral. Persons who arrange for the disposal or treatment of hazardous or toxic substances may also be liable for the costs of removal or remediation of hazardous or toxic substances at a disposal or treatment facility, whether or not the facility is owned or operated by the person. Certain environmental laws impose liability for the release of asbestos-containing materials into the air, and third parties may also seek recovery from owners or operators of real property for personal injury associated with asbestos-containing materials and other hazardous or toxic substances. Federal and state laws also regulate the operation and subsequent removal of certain underground storage tanks. In connection with the current or former ownership (direct or indirect), operation, management, development or control of real property, we may be considered an owner or operator of such apartment communities or as having arranged for the disposal or treatment of hazardous or toxic substances and, therefore, may be potentially liable for removal or remediation costs, as well as certain other costs, including governmental fines, and claims for injuries to persons and property.

Our current policy is to obtain a Phase I environmental study on each apartment community that we seek to acquire or develop, which generally does not involve invasive techniques such as soil or ground water sampling, and to proceed accordingly. However, there can be no assurance that the Phase I environmental studies or other environmental studies undertaken with respect to any of our current or future apartment communities will reveal:

Certain environmental laws impose liability on a previous owner of property to the extent that hazardous or toxic substances were present during the prior ownership period. A transfer of the property does not relieve an owner of such liability. Thus, we may have liability with respect to apartment communities previously sold by our predecessors or by us. There have been a number of lawsuits against owners and operators of multifamily apartment communities alleging personal injury and property damage caused by the presence of mold in residential real estate. Some of these lawsuits have resulted in substantial monetary judgments or settlements. Insurance carriers have reacted to these liability awards by excluding mold-related claims from standard policies and pricing mold endorsements separately. We have obtained a separate pollution insurance policy that covers mold-related claims and have adopted programs designed to minimize the existence of mold in any of our apartment communities as well as guidelines for promptly addressing and resolving reports of mold. To the extent not covered by our pollution policy, the presence of mold could expose us to liability from residents and others if property damage or health concerns, or allegations thereof, arise.

Our business and operations are subject to physical and transition risks related to climate change.

Many of our apartment communities are located in areas, such as coastal regions, that have historically been vulnerable to extreme weather events. To the extent climate change causes changes in weather patterns, areas where many of our communities are located could experience more frequent and intense extreme weather events and rising sea levels, which may cause significant damage to our properties, disrupt our operations and adversely impact our residents and rental revenue. Over time, such conditions could result in reduced demand for housing in areas where our communities are located, as well as higher costs for mitigating or repairing damage related to the effects of climate change, some which may not be fully covered by insurance. Similarly, these conditions may also negatively impact the types, pricing and terms of insurance we are able to procure.

Changes in federal, state and local laws and regulations on sustainable buildings could result in increased operating costs and capital expenditures for us to meet mandated levels of energy efficiency and/or greenhouse gas emissions performance with respect to our existing communities and could also require us to spend more on our new development communities without a corresponding increase in rental revenues. For example, various laws and regulations have been implemented or are under consideration to mitigate the effects of climate change caused by greenhouse gas emissions. Among other things, “green” building codes may seek to reduce emissions through the imposition of standards for design, construction materials, water and energy efficiency and waste management. The imposition of such requirements could increase the costs of maintaining or improving our existing communities (for example by requiring retrofits of existing communities to improve their energy efficiency and/or resistance to inclement weather) and developing new communities without creating corresponding increases in rental revenues, which would have an adverse impact on our operating results and could adversely impact the value of our properties. Additionally, if non-compliant with building efficiency standards, our existing communities may decrease in value.

Operations from new acquisitions, development projects, redevelopment activities, and platform initiatives may fail to perform as expected.

We intend to continue to acquire, develop and redevelop apartment communities as part of our business strategy. Newly acquired, developed or renovated properties may not perform as we expect. We may also overestimate the revenue (or underestimate the expenses) that a new or repositioned property may generate. The occupancy rates and rents at these properties may fail to meet our expectations underlying our investment.

In addition, with respect to acquisitions, we may be unable to quickly and efficiently integrate acquired apartment communities and new personnel into our existing operations, and the failure to successfully integrate those apartment communities or personnel would result in inefficiencies that could adversely affect our expected return on our investments. Likewise, we may acquire properties that are subject to liabilities or that have problems relating to environmental condition, state of title, physical condition or compliance with zoning laws, building codes or other legal requirements. In each case, our acquisition may be without any, or with only limited, recourse with respect to unknown liabilities or conditions, and we may be obligated to pay substantial sums to settle or cure it, which could adversely affect our cash flow and operating results.

Further, we intend to continue to implement platform initiatives across our apartment communities as part of our business strategy. Once implemented, platform initiatives may not perform as we expect. We may also overestimate the revenue (or expense savings) that such platform initiatives may generate.

Our implementation of long-standing succession planning could have adverse effects.

To reduce the risk of disruption from the planned retirement and unexpected departure of long-term employees and board members, we engage in succession planning to identify and develop in-house candidates for leadership and key executive positions within the company, recruit talented associates to fill areas of expertise needed within the company, and continually assess the needs of MAA’s Board of Directors to ensure stable governance of the company. In the last few years, we have transformed our executive team by elevating several internal candidates to key leadership positions. Such significant change over a relatively short period of time could result in unintended negative effects, such as creating employee dissatisfaction that could affect retention of other key employees or impacting short-term strategic initiatives, which could adversely affect our business.

We are subject to certain risks associated with selling apartment communities, which could limit our operational and financial flexibility.

We plan to sell apartment communities that no longer meet our long-term strategy. However, adverse market conditions could limit our ability to sell properties when we want and to change our portfolio promptly to meet our strategic objectives. Likewise, federal tax laws applicable to REITs limit our ability to profit on the sale of properties, and this limitation could prevent us from selling properties when market conditions are favorable. From time to time, we may 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 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.

Development and construction risks could impact our profitability.

As of December 31, 2025, we had eight development communities under construction representing 2,522 units once complete. We may make further investments in these and other development communities as opportunities arise and may do so through joint ventures with unaffiliated parties. Our development and construction activities are subject to the following risks:

Increasing real estate taxes, utilities and insurance premiums, as well as changes in the terms and conditions of our insurance policies, may negatively impact operating results.

As a result of our substantial real estate holdings, the cost of real estate taxes, utilities and insurance for our apartment communities represents a significant component of expense. These costs are subject to substantial increases and fluctuations, which can be widely outside of our control. For example, the current and potential impacts of climate change, along with the increased risk of extreme weather events and natural disasters have caused significant increases in our property insurance premiums and may adversely affect the availability and terms of coverage in the future. Additionally, “social inflation” has caused the cost of general liability claims to rise at a rate well above general economic inflation, primarily due to a trend in increasing litigation costs related to unpredictable jury verdicts for plaintiffs seeking large monetary relief for their injuries. Premises liability is of particular concern for multifamily apartment owners. In general, these factors have pressured insurance premiums and made it more challenging to obtain appropriate coverage at reasonable rates without assuming higher levels of self-retained risk. If the costs associated with real estate taxes, utilities and insurance premiums continue to rise without being offset by corresponding increases in rental revenues or, in the case of insurance, strategic self-retention of risk, our operating results could be negatively impacted, potentially affecting our ability to meet debt obligations and make distributions.

Short-term leases expose us to the effects of declining market rents, and we may be unable to renew leases or relet units as leases expire.

Our apartment leases are generally for a term of approximately one year. The short-term nature of these leases generally serves to reduce our risk to adverse effects of inflation as our leases allow for adjustments in the rental rate at the time of renewal, which may enable us to seek rent increases. However, since our leases typically permit the residents to leave at the end of the lease term without penalty, our revenues are impacted by declines in market rents more quickly than if our leases were for longer terms. If we are unable to promptly renew the leases or relet the units, or if the rental rates upon renewal or reletting are significantly lower than expected rates, then our financial condition and results of operations may be adversely affected.

We rely on information technology systems in our operations, and any breach or security failure of those systems could materially adversely affect our business, financial condition, results of operations and reputation.

We rely on proprietary and third-party information technology systems to process, transmit and store information and to manage or support our business processes. We store and maintain confidential financial and business information regarding us and persons with whom we do business on our information technology systems. We also 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 employees in connection with their employment. In addition, we engage third-party service providers that may collect and hold personally identifiable information of our residents, prospective residents and employees in connection with providing business services to us, including web hosting, property management, leasing, accounting, payroll and benefit services. The protection of the information technology systems on which we rely is critically important to us. As described in more detail under the heading "Cybersecurity" in this Annual Report on Form 10-K, we take steps, and generally require third-party service providers to take steps, to protect the security of the information maintained in our and our service providers’ information technology systems, including the use of systems, software, tools and monitoring to provide security for processing, transmitting and storing of the information. However, we face risks associated with breaches or security failures of the information technology systems on which we rely, which could result from, among other incidents, cyber-attacks or cyber-intrusions over the internet, malware, computer viruses or employee error or misconduct. This risk of a data breach or security failure, particularly through cyber-attacks or cyber-intrusion, has generally increased due to the rise in new technologies, such as ransomware and generative artificial intelligence, and the increased sophistication and activities of the perpetrators of attempted attacks and intrusions, including as a result of the intensification of state-sponsored cybersecurity attacks during periods of geopolitical conflict, such as the ongoing conflicts involving Ukraine and in the Middle East.

The security measures put in place by us and our service providers cannot provide absolute security and there can be no assurance that we or our service providers will not suffer a data security incident in the future, that unauthorized parties will not gain access to sensitive information stored on our or our service providers’ systems, that such access will not, whether temporarily or permanently, impact, interfere with or interrupt our operations, or that any such incident will be discovered in a timely manner. Even the most well-protected information, networks, systems and facilities remain potentially vulnerable as the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases are designed to not be detected and, in fact, may not be detected. The rapid evolution and increased adoption of artificial intelligence technologies, by us and our third-party service providers, may also heighten our cybersecurity risks by making cyber attacks more difficult to detect, contain and mitigate. In addition, third-party information technology providers may not provide us with fixes or updates to hardware or software in a manner as to avoid an unauthorized loss or disclosure or to address a known vulnerability, which may subject us to known threats or downtime as a result of those delays. Accordingly, we and our service providers may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures. Further, we may be required to expend significant additional resources to continue to enhance information security measures and internal processes and procedures or to investigate and remediate any information security vulnerabilities.

A data security incident could compromise our or our service providers’ information technology systems, and the information stored by us or our service providers, including personally identifiable information of residents, prospective residents and employees, could be accessed, misused, publicly disclosed, corrupted, lost or stolen. Any failure to prevent a data breach or a security failure of our or our service providers’ information technology systems could interrupt our operations, result in downtime, divert our planned efforts and resources from other projects, damage our reputation and brand, damage our competitive position, make it difficult for us to attract and retain residents, subject us to liability claims or regulatory penalties and could materially and adversely affect our business, financial condition or results of operations. Similarly, if our service providers fail to use adequate security or data protection processes, or use personal data in an unpermitted or improper manner, we may be liable for certain losses and it may damage our reputation.

A failure to keep pace with developments in technology could impair our operations or competitive position.

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

Compliance or failure to comply with laws and regulations could have an adverse effect on our operations and the values of our properties.

We must own, operate, manage, acquire, develop and redevelop our properties in compliance with numerous federal, state and local laws and regulations, some of which may conflict with one another or are subject to limited judicial or regulatory interpretations. These laws and regulations include landlord-tenant laws, employment laws, laws benefitting disabled persons, antitrust and other competition laws, privacy laws, tax laws, environmental laws, zoning laws, building codes and other laws regulating housing or that are generally applicable to our business and operations. Noncompliance with laws and regulations could expose us to liability, such as the imposition of fines by the government or the award of damages to private litigants, and could require us to make significant unanticipated expenditures, such as making modifications to our existing apartment communities or increasing construction costs for development communities.

As our industry becomes increasingly regulated, we do not know whether the legal requirements we are subject to will change or whether new requirements will be imposed. For example, privacy laws continue to evolve, with several states passing new data privacy laws that govern the collection, processing, use, security and disclosure of information about state residents, such as the Texas Data Privacy and Security Act. In addition, there are legislative efforts underway at the local, state and federal levels related to tenant screening limitations, affordable housing mandates, increased eviction notice periods, mandatory alternative dispute resolution and access to legal counsel for unrepresented tenants. Likewise, we have seen an increase in governments implementing, considering or being urged by tenant advocacy groups to consider rent control or rent stabilization laws and regulations and other tenants’ rights laws and regulations. New or changed legal requirements implemented in the markets in which we operate could require us to make significant unanticipated expenditures and could also limit our ability to recover increases in operating expenses, impose limitations on our ability to charge market rents or increase rents or charge certain fees, impose limitations on our ability to enforce remedies for the failure to pay rent or otherwise adversely impact our operations. Therefore, any such new or changed legal requirements could have a significant adverse impact on our results of operations and the value of our properties.

Legal proceedings that we become involved in from time to time could adversely affect our business.

As an owner, operator and developer of multifamily apartment communities, we may become involved in various legal proceedings, including, proceedings related to commercial, development, employment, competition, environmental, securities, shareholder, tenant or tort legal issues, some of which could result in a class action lawsuit. For example, we recently entered into a settlement agreement to settle lawsuits filed by plaintiffs individually and on behalf of a purported class of plaintiffs alleging that RealPage, Inc. and many of the largest owners and operators of apartment communities in the country, including us, conspired to artificially inflate multifamily residential rental prices above competitive levels using RealPage’s revenue management software in violation of state and federal antitrust laws. Similarly, other lawsuits alleging violations of antitrust and other laws have been filed by the District of Columbia and the Commonwealth of Kentucky against RealPage and a number of large apartment community owners and operators, including us. For more detail on these legal proceedings, see Note 11 to the consolidated financial statements included in this Annual Report on Form 10-K.

Legal proceedings, if decided adversely to or settled by us, and not covered by insurance, could result in liability material to our financial condition, results of operations or cash flows. Likewise, regardless of outcome, legal proceedings could result in substantial costs and expenses, result in operational changes in our business, affect the availability or cost of some of our insurance coverage and significantly divert the attention of our management. There can be no assurance that we will be able to prevail in, or achieve a favorable settlement of, any pending or future legal proceedings to which we become subject. In addition, other multifamily apartment owners could become involved in legal proceedings, the outcome of which could affect the way we conduct our business.

Extreme weather or natural disasters may cause significant damage to our properties.

Many of our apartment communities are located in areas that may be subject to extreme weather and natural disasters, such as floods, tornados, hurricanes, earthquakes, wildfires and major winter storms, the likelihood or frequency of which events could increase in part based on the impact of climate change. Such events may cause significant damage to our properties, disrupt our operations, and adversely impact our residents and rental revenue. There can be no assurances that such conditions will not have a material adverse effect on our properties, operations or business.

We may incur losses that are not covered by our insurance.

We have a comprehensive insurance program covering our properties and operations with limits of liability, deductibles and self-insured retentions that we negotiated with our insurance carriers. While we believe the terms and insured limits of these policies are appropriate for our business, there are certain types of losses, generally of a catastrophic nature, such as losses due to environmental matters, extreme weather or natural disasters, that are uninsurable or not economically insurable, or that may be insured subject to limitations, and therefore may be uninsured. We exercise our discretion in determining amounts, coverage limits, deductibles and self-insured retention provisions of our insurance, with a view to maintaining what we believe is appropriate insurance at a reasonable cost and on suitable terms.

Despite our insurance coverage, we may incur material losses due to uninsured risks, deductibles, self-insured retentions and/or losses in excess of coverage limits. In the event of a substantial loss, our insurance coverage may not be sufficient to cover the full current market value or current replacement cost of our lost investment or any settlement, fine or judgment against us resulting from legal proceedings. Inflation, changes in building codes and ordinances, environmental considerations and other factors also might make it infeasible to use insurance proceeds to replace a property after it has been damaged or destroyed. In addition, certain casualties or losses incurred may expose us in the future to higher insurance premiums.

We insure our properties and operations with insurance carriers that we believe have a good rating at the time our policies are put into effect. However, the financial condition of one or more of our insurance carriers may be negatively impacted, which would result in their inability to cover the full amount of any insured losses for which we submit a claim. Any such inability to pay future claims could have an adverse impact on our operating results. In addition, the failure, or exit or partial exit from an insurance market, of one or more insurance carriers may adversely affect our ability to obtain insurance in the amounts that we seek, increase our costs to renew or replace our insurance policies, or cause us to self-insure a greater portion of the risk.

Our financial condition, results of operations and cash flows could be materially adversely affected by factors relating to disease outbreaks and other public health events.

The U.S. has experienced, and may experience in the future, outbreaks of contagious diseases that affect public health and public perception of health risk. Our rental revenues and operating results depend significantly on the occupancy levels at our properties and the ability of our residents and commercial tenants to meet their rent obligations to us, which could be adversely affected by such disease outbreak or other public health events. For example, in response to the COVID-19 pandemic, extraordinary actions were taken by federal, state and local governmental authorities to combat the spread of COVID-19, including issuance of “stay-at-home” directives and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. These measures, while intended to protect human life, led to significantly reduced economic activity and a surge in unemployment throughout the U.S., including the markets where our properties are located, and they materially affected our ability to lease our properties and collect rental revenues.

The impact of a disease outbreak or other public health event on our business, financial condition, results of operations and cash flows is difficult to predict and, as was demonstrated by the COVID-19 pandemic, will depend on a number of factors, including the duration and scope of the event in the U.S. and any associated governmental directives; our residents’ and commercial tenants’ ability or willingness to pay rent in full on a timely basis; federal, state, local and industry-initiated efforts that may adversely affect the ability of landlords, including us, to collect rent and customary fees, adjust rental rates and enforce remedies for the failure to pay rent; the regulatory focus on landlords as distinguished from other providers of essential services; and the extent of the impact on our development and redevelopment programs and activities due to governmental directives or other restrictions, labor shortages, supply chain disruptions and escalating labor and material costs.

To the extent a disease outbreak or other public health event adversely affects our business, financial condition, results of operations and cash flows, it may also have the effect of heightening many of the other risks described in this Annual Report on Form 10-K.

Acts of violence could decrease the value of our assets and could have an adverse effect on our business and results of operations.

Our apartment communities could directly or indirectly be the location or target of actual or threatened terrorist attacks, crimes, shootings or other acts of violence, the occurrence of which could impact the value of our communities through damage, destruction, loss or increased security costs, as well as result in operational losses due to reduced rental demand, and the availability of insurance may be limited or may be subject to substantial costs. If such an incident were to occur at one of our apartment communities, we may also become subject to significant liability claims. In addition, the adverse effects that actual or threatened terrorist attacks could have on national economic conditions, as well as economic conditions in the markets in which we operate, could similarly have a material adverse effect on our business and results of operations.

Risks Related to Our Indebtedness and Financing Activities

Our substantial indebtedness could adversely affect our financial condition and results of operations.

As of December 31, 2025, the amount of our total debt was $5.4 billion. We may incur additional indebtedness in the future in connection with, among other things, our acquisition, development and operating activities.

The degree of our leverage creates significant risks, including that:

If any one of these events was to occur, our financial condition and results of operations could be materially and adversely affected.

We may be unable to renew, repay or refinance our outstanding debt, which could negatively impact our financial condition and results of operations.

We are subject to the normal risks associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest, the risk that either secured or unsecured indebtedness will not be able to be renewed, repaid or refinanced when due or that the terms of any renewal or refinancing will not be as favorable as the existing terms of such indebtedness. If we are unable to refinance our indebtedness on acceptable terms, if at all, we might be forced to dispose of one or more of our apartment communities on disadvantageous terms, which might result in losses to us. Such losses could have a material adverse effect on us and our ability to make payments on our debt and to make distributions. Furthermore, if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose upon the property, appoint a receiver and receive an assignment of rents and leases or pursue other remedies, all with a consequent loss of our revenues and asset value. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering our ability to meet the REIT distribution requirements of the Code.

Rising interest rates could adversely affect our results of operations and cash flows.

We have incurred and expect in the future to incur indebtedness that bears interest at variable rates. Interest rates increased significantly in 2022 and 2023, and while the Federal Reserve began cutting its benchmark interest rate in 2024, interest rates remain elevated. To the extent the current interest rate environment continues or interest rates increase further, we could experience higher interest expense on our variable-rate debt or increase interest rates when refinancing maturing fixed-rate debt, which could have a material adverse effect on us and our ability to make payments on our debt and to make distributions or cause us to be in default under certain debt instruments. In addition, the current interest rate environment, or any further increase in interest rates, may lead holders of shares of our common stock to demand a higher yield on their shares from distributions by us, which could adversely affect the market price for our common stock. Any increase in the federal funds rate due to key economic indicators, such as the unemployment rate or inflation, may cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the debt markets on favorable terms. Any continued adverse economic conditions could have a material adverse effect on our business, financial condition and results of operations.

We may incur additional debt in the future, which may adversely impact our financial condition.

We currently fund the acquisition and development of apartment communities partially through borrowings (including our commercial paper program and revolving credit facility) as well as from other sources such as sales of apartment communities which no longer meet our investment criteria. In addition, we may fund other of our capital requirements through debt. Our organizational documents do not contain any limitation on the amount of indebtedness that we may incur, and we may incur more debt in the future. Accordingly, subject to limitations on indebtedness set forth in various loan agreements and the indentures governing our unsecured senior notes, we could become more highly leveraged, resulting in an increase in debt service and an increased risk of default on our obligations, which could have a material adverse effect on our financial condition, our ability to access debt and equity capital markets in the future and our ability to make payments on our debt and to make distributions.

The restrictive terms of certain of our indebtedness may cause acceleration of debt payments.

As of December 31, 2025, we had outstanding borrowings of $5.4 billion. Our indebtedness contains financial covenants as to interest coverage ratios, maximum secured debt, maintenance of unencumbered asset value, and total debt to gross assets, among others, and cross default provisions with other material debt. Our ability to comply with these financial covenants may be affected by changes in our operating and financial performance, changes in general business and economic conditions, adverse regulatory developments or other events adversely impacting us. In the event that an event of default occurs, our lenders may declare borrowings under the respective loan agreements to be due and payable immediately, which could have a material adverse effect on our financial condition and our ability to make payments on our debt and to make distributions.

A downgrade in our credit ratings could have a material adverse effect on our business, financial condition and results of operations.

We have a significant amount of unsecured debt outstanding. We are currently assigned corporate credit ratings from each of the three ratings agencies based on their evaluation of our creditworthiness. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality and sustainability of cash flows and earnings. If our credit ratings are downgraded or other negative action is taken, we could be required to pay additional interest and fees on our outstanding borrowings. In addition, a downgrade may adversely impact our ability to borrow secured and unsecured debt, increase our borrowing costs and otherwise limit our access to capital, which could adversely affect our business, financial condition and results of operations.

Financing may not be available and could be dilutive.

Our capital requirements depend on numerous factors, including the occupancy and turnover rates of our apartment communities, development and capital expenditures, costs of operations and potential acquisitions. We cannot accurately predict the timing and amount of our capital requirements. If our capital requirements vary materially from our plans, we may require additional financing sooner than anticipated.

We and other companies in the real estate industry have experienced limited availability of financing from time to time. Dislocations and liquidity disruptions in capital and credit markets could impact liquidity in the debt markets, which could result in financing terms that are less attractive to us and/or the unavailability of certain types of debt financing. Likewise, disruptions could impede the ability of our counterparties to perform on their contractual obligations. Should the capital and credit markets experience volatility and the availability of funds again becomes limited, or be available only on unattractive terms, we will incur increased costs associated with issuing debt instruments. In addition, it is possible that our ability to access the capital and credit markets may be limited or precluded by these or other factors at a time when we would like, or need, to do so, which would adversely impact our ability to refinance maturing debt and/or react to changing economic and business conditions. Uncertainty in the credit markets could negatively impact our ability to make acquisitions and make it more difficult or not possible for us to sell properties or may adversely affect the price we receive for properties that we do sell, as prospective buyers may experience increased costs of debt financing or difficulties in obtaining debt financing. Potential continued disruptions in the financial markets could also have other unknown adverse effects on us or the economy generally and may cause the price of our securities to fluctuate significantly and/or to decline. If we issue additional equity securities to obtain additional capital, the interest of our existing shareholders could be diluted.

Risks Related to MAA’s Organization and Ownership of Its Stock

MAA’s ownership limit restricts the transferability of its capital stock.

MAA’s charter limits ownership of its capital stock by any single shareholder to 9.9% of the value of all outstanding shares of its capital stock, both common and preferred, unless approved by its Board of Directors. The charter also prohibits anyone from buying shares if the purchase would result in it losing REIT status. This could happen if a share transaction results in fewer than 100 persons owning all of its shares or in five or fewer persons, applying certain broad attribution rules of the Code, owning 50% or more of its shares. If an investor acquires shares in excess of the ownership limit or in violation of the ownership requirements of the Code for REITs, MAA:

The redemption price may be paid, at MAA’s option, by delivering one OP Unit (subject to adjustment from time to time in the event of, among other things, stock splits, stock dividends or recapitalizations affecting its common stock or certain mergers, consolidations or asset transfers by MAA) issued by the Operating Partnership for each excess share being redeemed.

If an investor acquires shares in violation of the limits on ownership described above, the holder may:

Future offerings of debt or equity securities, which may rank senior to MAA’s stock, may adversely affect the market price of MAA’s stock.

If we decide to issue additional debt securities in the future, which would rank senior to MAA’s common stock, it is likely that they will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Additionally, any equity securities or convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of MAA’s common stock and may result in dilution to owners of MAA’s common stock. We and, indirectly, MAA’s shareholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future offerings. Thus, holders of MAA’s common stock will bear the risk of our future offerings reducing the market price of MAA’s common stock and diluting the value of their stock holdings.

The form, timing and amount of dividend distributions in future periods may vary and be impacted by economic and other considerations.

Though MAA’s Board of Directors has a history of declaring dividends in advance of the quarter they are paid, the form, timing and amount of dividend distributions will be declared, and standing practice changed, at the discretion of the Board of Directors. The form, timing and amount of dividend distributions 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 MAA’s Board of Directors may consider relevant. MAA’s Board of Directors may modify MAA’s dividend policy from time to time.

Provisions of MAA’s charter and Tennessee law may limit the ability of a third party to acquire control of MAA.

Ownership Limit

The 9.9% ownership limit discussed above may have the effect of precluding acquisition of control of MAA by a third party without the consent of MAA’s Board of Directors.

Preferred Stock

MAA’s charter authorizes its Board of Directors to issue up to 20,000,000 shares of preferred stock, 868,000 of which have been designated as 8.50% Series I Cumulative Redeemable Preferred Stock, which we refer to as MAA Series I preferred stock. In addition to the MAA Series I preferred stock, the Board of Directors may establish the preferences and rights of any other series of preferred shares issued. The issuance of preferred stock could have the effect of delaying or preventing someone from taking control of MAA, even if a change in control were in MAA shareholders’ best interests. As of December 31, 2025, 867,846 shares of preferred stock were issued and outstanding, all of which shares were MAA Series I preferred stock.

Tennessee Anti-Takeover Statutes

As a Tennessee corporation, MAA is subject to various legislative acts, which impose restrictions on and require compliance with procedures designed to protect shareholders against unfair or coercive mergers and acquisitions. These statutes may delay or prevent offers to acquire MAA and increase the difficulty of consummating any such offers, even if MAA’s acquisition would be in MAA shareholders’ best interests.

Third-party expectations relating to environmental, social and governance factors may impose additional costs and expose us to new risks.

We have a significant institutional investor base, and there is a heightened focus from institutional investors and other stakeholders on corporate responsibility, specifically related to environmental, social and governance, or ESG, factors. Some institutional investors may use these factors to guide their investment strategies, and many institutional investors focus on positive ESG business practices and may consider a company’s ESG score when making an investment decision. In addition, many institutional investors may use ESG scores to benchmark companies against their peers. 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’ ESG practices are assessed are evolving and inconsistent, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy any new or contradictory criteria. Alternatively, if we elect not to or are unable to satisfy new criteria or do not meet the criteria of a specific third-party provider, some investors may conclude that our ESG business practices are inadequate. We may face reputational damage in the event that our corporate responsibility standards do not meet the standards set by various stakeholders. In addition, in the event that we communicate certain ESG initiatives and goals, we could fail, or be perceived to have failed, in our achievement of our initiatives or goals, or we could be criticized for the scope of our initiatives or goals or the achievement of our initiatives or goals may be costly. If we fail to satisfy the ESG expectations of investors and other stakeholders or our initiatives are not executed as planned, our reputation and financial results and the market price of MAA’s common stock could be adversely affected.

Market interest rates may have an adverse effect on the market value of MAA’s common stock.

The market price of shares of common stock of a REIT may be affected by the distribution rate on those shares, as a percentage of the price of the shares, relative to market interest rates. If market interest rates increase, prospective purchasers of MAA’s common stock may expect a higher annual distribution rate. Higher interest rates would not, however, result in more funds for MAA to distribute and, in fact, would likely increase MAA’s future borrowing costs and potentially decrease funds available for distribution. This could cause the market price of MAA’s common stock to go down.

Changes in market conditions or a failure to meet the market’s expectations with regard to our results of operations and cash distributions could adversely affect the market price of MAA’s common stock.

We believe that the market value of a REIT’s equity securities is based primarily upon the market’s perception of the REIT’s growth potential and its current and potential future cash distributions, and is secondarily based upon the real estate market value of the underlying assets. For that reason, MAA’s common stock may trade at prices that are higher or lower than the net asset value per share. To the extent we retain operating cash flow for investment purposes, working capital reserves or other purposes, these retained funds, while increasing the value of our underlying assets, may not correspondingly increase the market price of MAA’s common stock. In addition, we are subject to the risk that our cash flow will be insufficient to pay distributions to MAA’s shareholders. Our failure to meet the market’s expectations with regard to future earnings and cash distributions would likely adversely affect the market price of MAA’s common stock.

The stock markets, including the NYSE, on which MAA lists its common stock, have, at times, experienced significant price and volume fluctuations. As a result, the market price of MAA’s common stock could be similarly volatile, and investors in MAA’s common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. The market price of MAA’s publicly traded securities may be affected by many factors, including:

In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources.

Risks Related to the Operating Partnership’s Organization and Ownership of OP Units

The Operating Partnership’s existing unitholders have limited approval rights, which may prevent the Operating Partnership’s sole general partner, MAA, from completing a change of control transaction that may be in the best interests of all unitholders of the Operating Partnership and all shareholders of MAA.

MAA may not engage in a sale or other disposition of all or substantially all of the assets of the Operating Partnership, dissolve the Operating Partnership or, upon the occurrence of certain triggering events, take any action that would result in any unitholder realizing taxable gain, without the approval of the holders of a majority of the outstanding OP Units held by holders other than MAA or its affiliates, or Class A OP Units. The right of the holders of our Class A OP Units to vote on these transactions could limit MAA’s ability to complete a change of control transaction that might otherwise be in the best interest of all unitholders of the Operating Partnership and all shareholders of MAA.

In certain circumstances, certain of the Operating Partnership’s unitholders must approve the Operating Partnership’s sale of certain properties contributed by the unitholders.

In certain circumstances, as detailed in the limited partnership agreement of the Operating Partnership, the Operating Partnership may not sell or otherwise transfer certain properties unless a specified percentage of the limited partners who were partners in the limited partnership holding such properties at the time of its acquisition by us approves such sale or transfer. The exercise of these approval rights by the Operating Partnership’s unitholders could delay or prevent the Operating Partnership from completing a transaction that may be in the best interest of all unitholders of the Operating Partnership and all shareholders of MAA.

MAA, its officers and directors have substantial influence over the Operating Partnership’s affairs.

MAA, as the Operating Partnership’s sole general partner and acting through its officers and directors, has a substantial influence on the Operating Partnership’s affairs. MAA, its officers and directors could exercise their influence in a manner that is not in the best interest of the unitholders of the Operating Partnership. Also, as of December 31, 2025, MAA owned approximately 97.5% of the OP Units. As such, MAA has substantial influence on the outcome of substantially all matters submitted to the Operating Partnership’s unitholders for approval.

Insufficient cash flow from operations or a decline in the market price of MAA’s common stock may reduce the amount of cash available to the Operating Partnership to meet its obligations.

The Operating Partnership is subject to the risk that its cash flow will be insufficient to make payments on its debt and to make distributions to its unitholders, which may cause MAA to not have the funds to make distributions to its shareholders. MAA’s failure to meet the market’s expectations with regard to future results of operations and cash distributions would likely adversely affect the market price of its shares and thus potentially reduce MAA’s ability to contribute funds from issuances down to the Operating Partnership, resulting in a lower level of cash available for investment, to make payments on its debt or to make distributions to its unitholders.

Risks Related to Tax Laws

Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to shareholders.

If MAA fails to qualify as a REIT for federal income tax purposes, MAA will be subject to federal income tax on its taxable income at regular corporate rates without the benefit of the dividends paid deduction applicable to REITs. In addition, unless MAA is entitled to relief under applicable statutory provisions, MAA would be ineligible to make an election for treatment as a REIT for the four taxable years following the year in which it loses its 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 MAA’s shareholders. MAA’s failure to qualify as a REIT also could impair its ability to expand its business and raise capital, and would adversely affect the value of MAA’s common stock.

MAA believes that it is organized and qualified as a REIT, and MAA intends to operate in a manner that will allow it to continue to qualify as a REIT. MAA cannot assure, however, that it is qualified or will remain qualified as a REIT. 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 MAA’s control. 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 qualification as a REIT. Even if MAA qualifies as a REIT, MAA will be subject to various federal, state and local taxes, including property taxes and income taxes on taxable income that MAA does not timely distribute to its shareholders. In addition, MAA may hold certain assets and engage in certain activities that a REIT could not engage in directly through its taxable REIT subsidiaries, or TRS, and those TRS will be subject to federal income tax at regular corporate rates on their taxable income without the benefit of the dividends paid deduction applicable to REITs.

Furthermore, we have a subsidiary that has elected to be treated as a REIT, and if our subsidiary REIT were to fail to qualify as a REIT, it is possible that we also would fail to qualify as a REIT unless we (or the subsidiary REIT) could qualify for certain relief provisions. The qualification of our subsidiary REIT as a REIT will depend on satisfaction, on an annual or quarterly basis, of numerous requirements set forth in highly technical and complex provisions of the Code for which there are only limited judicial or administrative interpretations. A determination as to whether such requirements are satisfied involves various factual matters and circumstances not entirely within our control. The fact that we hold substantially all of our assets through the Operating Partnership and its subsidiaries further complicates the application of the REIT requirements for us. No assurance can be given that our subsidiary REIT will qualify as a REIT for any particular year.

The Operating Partnership may fail to be treated as a partnership for federal income tax purposes.

We believe that the Operating Partnership qualifies, and has so qualified since its formation, as a partnership for federal income tax purposes and not as a publicly traded partnership taxable as a corporation. No assurance can be provided, however, that the Internal Revenue Service, or IRS, will not challenge the treatment of the Operating Partnership as a partnership for federal income tax purposes or that a court would not sustain such a challenge. If the IRS were successful in treating the Operating Partnership as a corporation for federal income tax purposes, then the taxable income of the Operating Partnership would be taxable at regular corporate income tax rates. In addition, the treatment of the Operating Partnership as a corporation would cause MAA to fail to qualify as a REIT. See “Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to shareholders” above.

Certain dispositions of property by us may generate prohibited transaction income, resulting in a 100% penalty tax on any gain attributable to the disposition.

Any gain resulting from a transfer of property that we hold as inventory or primarily for sale to customers in the ordinary course of business would be treated for federal income tax purposes as income from a prohibited transaction that is subject to a 100% penalty tax. Since we acquire properties for investment purposes, we do not believe that our occasional transfers or disposals of property would be considered prohibited transactions. Whether property is held for investment purposes is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. As such, the IRS may contend that certain transfers or disposals of properties by us are prohibited transactions. If the IRS were to argue successfully that a transfer or disposition of property constituted a prohibited transaction, then we would be required to pay a 100% penalty tax on any gain allocable to us from the prohibited transaction. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT for federal income tax purposes. A safe harbor to the characterization of the disposition of property as a prohibited transaction and the resulting imposition of the 100% tax is available; however, we cannot assure that we will be able to comply with such safe harbor in connection with any property dispositions.

Legislative or regulatory income tax changes related to REITs could materially and adversely affect us.

The U.S. federal income tax laws and regulations governing REITs and their shareholders, as well as the administrative interpretations of those laws and regulations, are constantly under review and may be changed at any time, possibly with retroactive effect. No assurance can be given as to whether, when, or in what form changes to the U.S. federal income tax laws applicable to us and MAA’s shareholders may be enacted. Changes to the U.S. federal income tax laws and interpretations of U.S. federal tax laws could adversely affect an investment in MAA’s stock.

Market Information

MAA’s common stock has been listed and traded on the NYSE under the symbol “MAA” since its initial public offering in February 1994. As of February 3, 2026, there were approximately 1,900 holders of record of the common stock. MAA believes it has a significantly larger number of beneficial owners of its common stock.

MAA has a history of declaring dividends to holders of MAA common stock. The timing and amount of future dividends will depend on actual cash flows from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as MAA’s Board of Directors deems relevant. MAA’s Board of Directors may modify MAA’s dividend policy from time to time.

Direct Stock Purchase and Distribution Reinvestment Plan

MAA has established the dividend and distribution reinvestment stock purchase plan, or DRSPP, under which holders of common stock, preferred stock and OP Units can elect to automatically reinvest their distributions in shares of MAA’s common stock. The DRSPP also allows for the optional purchase of MAA’s common stock of at least $250, but not more than $5,000 in any given month. In its absolute discretion, MAA may grant waivers to allow for optional cash payments in excess of $5,000. To fulfill its obligations under the DRSPP, MAA may either issue additional shares of common stock or repurchase common stock in the open market. MAA may elect to sell shares under the DRSPP at up to a 5% discount. During the year ended December 31, 2025, MAA issued 10,006 shares through the DRSPP and no shares were issued at a discount.

Mid-America Apartments, L.P.

Operating Partnership Units

There is no established public trading market for the Operating Partnership’s OP Units. From time to time, we issue shares of MAA’s common stock in exchange for OP Units tendered to the Operating Partnership for redemption in accordance with the provisions of the Operating Partnership’s limited partnership agreement. As of December 31, 2025, there were 119,819,916 OP Units outstanding in the Operating Partnership, of which 116,878,077 OP Units, or 97.5%, were owned by MAA and 2,941,839 OP Units, or 2.5%, were owned by limited partners. Under the terms of the Operating Partnership’s limited partnership agreement, the limited partner holders of OP Units have the right to require the Operating Partnership to redeem all or a portion of the OP Units held by the holder in exchange for one share of MAA common stock per one OP Unit or a cash payment based on the market value of MAA’s common stock at the time of redemption, at the option of MAA. During the year ended December 31, 2025, MAA issued a total of 133,714 shares of common stock upon redemption of OP Units.

At-the-Market Equity Offering Program

MAA has entered into an at-the-money equity offering program, or ATM program, enabling MAA to sell shares of its common stock into the existing market at current market prices from time to time to or through the sales agents under the ATM program. Pursuant to the ATM program, MAA from time to time may also enter into forward sale agreements and sell shares of common stock pursuant to these agreements. Through the ATM program, MAA may issue up to an aggregate of 4.0 million shares of its common stock at such times as determined by MAA. MAA has no obligation to issue shares through the ATM program. During the year ended December 31, 2025, MAA did not sell any shares of common stock under the ATM program. As of December 31, 2025, 4.0 million shares of MAA’s common stock remained issuable under the ATM program.

Stock Repurchase Plan

In December 2015, MAA’s Board of Directors authorized the repurchase of up to 4.0 million shares of MAA common stock, which represented approximately 5.3% of MAA’s common stock outstanding at the time of such authorization. From time to time, we may repurchase shares under this authorization when we believe that shareholder value would be enhanced. Factors affecting this determination include, among others, the share price and expected rates of return. As of December 31, 2025, 206,916 shares have been repurchased under the authorization. See “Purchases of Equity Securities” below.

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

The following discussion analyzes the financial condition and results of operations of both MAA and the Operating Partnership, of which MAA is the sole general partner and in which MAA owned a 97.5% interest as of December 31, 2025. MAA conducts all of its business through the Operating Partnership and its various subsidiaries. This discussion should be read in conjunction with the consolidated financial statements and notes thereto included in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results, performance and achievements may differ materially from those expressed or implied by such forward-looking statements as a result of many factors, including, but not limited to, those under the heading “Risk Factors” in this Annual Report on Form 10-K.

MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. We own, operate, acquire and selectively develop apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the U.S. As of December 31, 2025, we owned and operated 293 apartment communities (which does not include development communities under construction) through the Operating Partnership and its subsidiaries, and had an ownership interest in one apartment community through an unconsolidated real estate joint venture. In addition, as of December 31, 2025, we had eight development communities under construction, and 35 of our apartment communities included retail components. Our apartment communities, including development communities under construction, were located across 16 states and the District of Columbia as of December 31, 2025.

We report in two segments, Same Store and Non-Same Store and Other. Our Same Store segment represents those apartment communities that have been owned and stabilized for at least 12 months as of the first day of the calendar year. Communities are considered stabilized when achieving 90% average physical occupancy for 90 days. Our Non-Same Store and Other segment includes recently acquired communities, communities being developed or in lease-up, communities that have been disposed of or identified for disposition, communities that have incurred a significant casualty loss and stabilized communities that do not meet the requirements to be Same Store communities. Also included in our Non-Same Store and Other segment are non-multifamily activities and expenses related to severe weather events, including hurricanes and winter storms. Additional information regarding the composition of our segments is included in Note 13 to the consolidated financial statements included in this Annual Report on Form 10-K.

Overview

For the year ended December 31, 2025, net income available for MAA common shareholders was $443.2 million as compared to $523.9 million for the year ended December 31, 2024. Results for the year ended December 31, 2025 included $72.1 million of gain related to the sale of depreciable real estate assets, $6.1 million of non-cash gain, net of tax, from investments, $4.6 million in net casualty gain and $1.1 million of non-cash gain related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares, partially offset by $61.9 million of legal costs and settlements. Results for the year ended December 31, 2024 included $55.0 million of gain related to the sale of depreciable real estate assets, $11.2 million of gain on the consolidation of a third-party development, $9.3 million in net casualty gain and $6.1 million of non-cash gain, net of tax, from investments, partially offset by $18.8 million of non-cash loss related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares and $9.4 million of legal costs and settlements. Revenues for the year ended December 31, 2025 increased 0.8% as compared to the year ended December 31, 2024, driven by an 18.9% increase in our Non-Same Store and Other segment. Property operating expenses, excluding depreciation and amortization, for the year ended December 31, 2025 increased by 2.2% as compared to the year ended December 31, 2024, driven by a 2.0% increase in our Same Store segment and 4.3% increase in our Non-Same Store and Other segment. The primary drivers of these changes are discussed in the “Results of Operations” section.

Trends

During the year ended December 31, 2025, the change in revenue for our Same Store segment was primarily driven by average effective rent per unit. The average effective rent per unit for our Same Store segment decreased to $1,690 for the year ended December 31, 2025 as compared to $1,698 for the year ended December 31, 2024. This represents a decrease of 0.5% for the year ended December 31, 2025 as compared to the year ended December 31, 2024. Average effective rent per unit represents the average of gross rent amounts, after the effect of leasing concessions, for occupied apartment units plus prevalent market rates asked for unoccupied apartment units, divided by the total number of units. Leasing concessions represent discounts to the current market rate. We believe average effective rent per unit is a helpful measurement in evaluating average pricing; however, it does not represent actual rental revenue collected per unit.

For the year ended December 31, 2025, average physical occupancy for our Same Store segment was 95.6% as compared to 95.5% for the year ended December 31, 2024. Average physical occupancy is a measurement of the total number of our apartment units that are occupied by residents, and it represents the average of the daily physical occupancy for the period.

As of December 31, 2025, resident turnover for our Same Store segment was 40.2% as compared to 42.0% as of December 31, 2024. Resident turnover represents resident move outs, excluding transfers within the Same Store segment, as a percentage of expiring leases on a trailing twelve-month basis as of the end of the reported period.

An important part of our portfolio strategy is to maintain diversity of markets, submarkets, product types and price points in the Southeast, Southwest and Mid-Atlantic regions of the U.S. We have multifamily assets in 38 defined markets, with a presence in approximately 150 submarkets and a mixture of garden-style, mid-rise and high-rise communities. This diversity helps to mitigate exposure to economic issues, including supply and demand factors, in any one geographic market or area. We believe that a well-balanced portfolio, including both urban and suburban locations, with a broad range of monthly rent price points, will provide higher performance and lower volatility throughout the full economic cycle.

Demand for apartments in our markets was solid during 2025, as evidenced by improving occupancy and blended pricing trends, solid traffic patterns and lead volumes along with record low resident turnover. We believe demand for apartments is primarily driven by general economic conditions in our markets and is particularly correlated to job growth, population growth, household formation, in-migration and housing affordability over the long term. We continue to monitor pressures surrounding housing supply, inflation trends and general economic conditions. A worsening of the current environment could contribute to uncertain rent collections going forward, suppress demand for apartments and could drive lower rent growth on new leases and renewals than what we achieved in the year ended December 31, 2025. New supply deliveries, while still elevated by historical standards, continue to be absorbed in a steady manner as the demand for apartment housing remains solid. We believe that we will continue to see a decline in new apartment deliveries in calendar year 2026.

Access to the financial markets remains available for high-credit rated borrowers, such as ourselves. However, overall borrowing costs remain at elevated levels as compared to our in-place fixed rate debt, and we expect this trend to continue. As of December 31, 2025, we had $676.0 million of variable rate debt outstanding under our commercial paper program. Our continued exposure to elevated interest rates is primarily attributable to existing variable-rate borrowings and any future financing activities.

Results of Operations

For the year ended December 31, 2025, we achieved net income available for MAA common shareholders of $443.2 million, a 15.4% decrease as compared to the year ended December 31, 2024, and total revenue growth of $18.1 million, representing a 0.8% increase in property revenues as compared to the year ended December 31, 2024. The following discussion describes the primary drivers of the decrease in net income available for MAA common shareholders for the year ended December 31, 2025 as compared to the year ended December 31, 2024. A discussion of the results of operations for the year ended December 31, 2024 as compared to the year ended December 31, 2023 is found in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 7, 2025, which is available free of charge on the SEC’s website at https://www.sec.gov and on our website at https://www.maac.com, on the “For Investors” page under “Filings and Financials—Annual Reports.”

Property Revenues

The following table reflects our property revenues by segment for the years ended December 31, 2025 and 2024 (dollars in thousands):

The increase in property revenues for our Non-Same Store and Other segment for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was the primary driver of total property revenue growth. The Same Store segment generated a 0.1% decrease in revenues for the year ended December 31, 2025, primarily the result of a decrease in average effective rent per unit of 0.5% as compared to the year ended December 31, 2024. The increase in property revenues from the Non-Same Store and Other segment for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was primarily the result of increased revenues from completed development communities and recently acquired communities.

Property Operating Expenses

Property operating expenses include costs for property personnel, building repairs and maintenance, real estate taxes, insurance, utilities, landscaping and other operating expenses. The following table reflects our property operating expenses by segment for the years ended December 31, 2025 and 2024 (dollars in thousands):

The increase in property operating expenses for our Same Store segment for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was primarily driven by increases in personnel expense of $7.2 million, utilities expense of $5.3 million, building repair and maintenance expense of $2.5 million, and marketing expense of $1.5 million, partially offset by a decrease in property tax expense of $2.2 million. The increase in property operating expenses from the Non-Same Store and Other segment for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was primarily the result of increased expenses from completed development communities and recently acquired communities.

Depreciation and Amortization

Depreciation and amortization expense for the year ended December 31, 2025 was $622.3 million, an increase of $36.7 million as compared to the year ended December 31, 2024. The increase in depreciation and amortization expense for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was primarily driven by the recognition of depreciation expense associated with our completed development communities and capital spend activities made in the normal course of business during the year ended December 31, 2025, partially offset from decreased depreciation expense from communities disposed of during the years ended December 31, 2025 and 2024.

Other Income and Expenses

Property management expenses for the year ended December 31, 2025 were $74.8 million, an increase of $2.7 million as compared to the year ended December 31, 2024. General and administrative expenses for the year ended December 31, 2025 were $54.8 million, a decrease of $1.7 million as compared to the year ended December 31, 2024.

Interest expense for the year ended December 31, 2025 was $185.3 million, an increase of $16.7 million as compared to the year ended December 31, 2024. The increase was due to an increase in our average outstanding debt balance and an increase of nine basis points in our effective interest rate, partially offset by an increase in capitalized interest during the year ended December 31, 2025 as compared to the year ended December 31, 2024.

For the years ended December 31, 2025 and 2024, we disposed of two apartment communities each year, resulting in gains on sale of depreciable real estate assets of $72.0 million and $55.0 million, respectively. During the years ended December 31, 2025 and 2024, we did not dispose of any land parcels.

Other non-operating expense (income) for the year ended December 31, 2025 was $47.2 million of expense as compared to $1.7 million of income for the year ended December 31, 2024. The expense for the year ended December 31, 2025 was primarily driven by $61.9 million of legal costs and settlements, partially offset by $7.5 million of non-cash gain from investments, $4.6 million of net casualty related recoveries and $1.1 million of non-cash gain related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares. The income for the year ended December 31, 2024 was primarily driven by $11.2 million of gain on the consolidation of a third-party development, $9.3 million of net casualty related recoveries, $7.8 million of non-cash gain from investments and miscellaneous income of $1.0 million, partially offset by $18.8 million of non-cash loss related to the fair value adjustment of the embedded derivative in the MAA Series I preferred shares and $9.4 million of legal costs and settlements.

Non-GAAP Financial Measures

Funds from Operations and Core Funds from Operations

Funds from operations, or FFO, a non-GAAP financial measure, represents net income available for MAA common shareholders (computed in accordance with GAAP) excluding gains or losses on disposition of operating properties and asset impairment and gain on consolidation of third-party development, plus depreciation and amortization of real estate assets, net income attributable to noncontrolling interests and adjustments for joint ventures. Because net income attributable to noncontrolling interests is added back, FFO, when used in this Annual Report on Form 10-K, represents FFO attributable to common shareholders and unitholders.

FFO should not be considered as an alternative to net income available for MAA common shareholders or any other GAAP measurement, as an indicator of operating performance or as an alternative to cash flow from operating, investing and financing activities as a measure of liquidity. Management believes that FFO is helpful to investors in understanding our operating performance, primarily because its calculation excludes depreciation and amortization expense on real estate assets and gain on sale of depreciable real estate assets. We believe that GAAP historical cost depreciation of real estate assets is generally not correlated with changes in the value of those assets, whose value does not diminish predictably over time, as historical cost depreciation implies. While our calculation of FFO is in accordance with the National Association of Real Estate Investment Trusts’, or NAREIT’s, definition, it may differ from the methodology for calculating FFO utilized by other REITs and, accordingly, may not be comparable to such other REITs.

Core FFO represents FFO as adjusted for items that are not considered part of our core business operations, such as adjustments related to the fair value of the embedded derivative in the MAA Series I preferred shares; gain or loss on sale of non-depreciable assets; gain or loss on investments, net of tax; casualty related charges and (recoveries), net; gain or loss on debt extinguishment; legal costs, settlements and (recoveries), net; and mark-to-market debt adjustments. Because net income attributable to noncontrolling interests is added back to FFO, Core FFO, when used in this Annual Report on Form 10-K, represents Core FFO attributable to common shareholders and unitholders.

Core FFO should not be considered as an alternative to net income available for MAA common shareholders, or any other GAAP measurement, as an indicator of operating performance or as an alternative to cash flow from operating, investing and financing activities as a measure of liquidity. Management believes that Core FFO is helpful in understanding our core operating performance between periods in that it removes certain items that by their nature are not comparable over periods and therefore tend to obscure actual operating performance from rental activities. While our definition of Core FFO may be similar to others in the industry, our methodology for calculating Core FFO may differ from that utilized by other REITs and, accordingly, may not be comparable to such other REITs.

The following table presents a reconciliation of net income available for MAA common shareholders to FFO and Core FFO for the years ended December 31, 2025 and 2024, as we believe net income available for MAA common shareholders is the most directly comparable GAAP measure (dollars in thousands):
