## No Match in Current: If any REIT previously acquired by us failed to qualify as a REIT for U.S. federal income tax purposes, we would incur adverse tax consequences and our financial condition and results of operations would be materially adversely affected.

*This section from the 2024 filing does not have a high-confidence textual match in 2025. It may have been removed, merged, or substantially reworded.*

In the past, we have acquired companies that operated in a manner intended to allow them to qualify as REITs for U.S. federal income tax purposes. If any such REIT previously acquired by MAA, referred to as a Merged REIT, is determined to have lost its REIT status at any time prior to its merger with MAA, MAA would be subject to serious adverse tax consequences, including: •MAA would be required to pay U.S. federal income tax at regular corporate rates on the taxable income of such Merged REIT without the benefit of the dividends paid deduction for the taxable years that the Merged REIT did not qualify as a REIT and for which the statute of limitations period remains open; and MAA would be required to pay U.S. federal income tax at regular corporate rates on the taxable income of such Merged REIT without the benefit of the dividends paid deduction for the taxable years that the Merged REIT did not qualify as a REIT and for which the statute of limitations period remains open; and •MAA would be required to pay any federal alternative minimum tax liability of the Merged REIT and any applicable state and local tax liability, in each case, for all taxable years that remain open under the applicable statute of limitations periods. MAA would be required to pay any federal alternative minimum tax liability of the Merged REIT and any applicable state and local tax liability, in each case, for all taxable years that remain open under the applicable statute of limitations periods. MAA is liable for any tax liability of a Merged REIT with respect to any periods prior to the merger of such Merged REIT with MAA. If a Merged REIT failed to qualify as a REIT, then in the event of a taxable disposition by MAA of an asset previously held by the Merged REIT during a specified period of up to five years following the merger of the Merged REIT with MAA, MAA will be subject to corporate income tax with respect to any built-in gain inherent in such asset as of the date of such merger. In addition, unless an applicable statutory relief provision applies, if a Merged REIT failed to qualify as a REIT for a taxable year, then the Merged REIT would not have been entitled to re-elect to be taxed as a REIT until the fifth taxable year following the year during which it was disqualified. Furthermore, if both MAA and a Merged REIT were "investment companies" under the "investment company" rules set forth in Section 368 of the Code at the time of the merger of MAA and such Merged REIT, the failure of MAA or such Merged REIT to have qualified as a REIT at the time of their merger could result in such merger being treated as taxable for federal income tax purposes. As a result of all these factors, the failure by a Merged REIT to have qualified as a REIT could jeopardize MAA's qualification as a REIT and require the Operating Partnership to provide material amounts of cash to MAA to satisfy MAA's additional tax liabilities and, therefore, could have a material adverse effect on MAA's business prospects, financial condition or results of operations and on MAA's ability to make payments on our debt and to make distributions. 23

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

**Key changes:**

- Reworded sentence: "Many of our apartment communities are located in areas, such as coastal regions, that have historically been vulnerable to extreme weather events."
- Reworded sentence: "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."

**Prior (2024):**

Many of our apartment communities are located along or near coastal areas that have historically been subject to the risk of 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. Over time, such conditions could result in reduced demand for housing in areas where our communities are located and increased costs related to further developing our communities to mitigate the effects of climate change or repairing damage related to the effects of climate change that may or may not be fully covered by insurance. Likewise, such conditions also may 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/or capital expenditures to improve the energy efficiency of 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 usage and 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. 12

**Current (2025):**

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. 12 12 12

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

**Key changes:**

- Reworded sentence: "For example, we are currently a defendant, among other companies, in lawsuits filed by plaintiffs individually and on behalf of a purported class of plaintiffs alleging that RealPage, Inc."

**Prior (2024):**

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. As described in more detail in Note 11 to the consolidated financial statements included in this Annual Report on Form 10-K, we are currently a defendant, among other companies, in lawsuits filed by plaintiffs individually and on behalf of a purported class of plaintiffs alleging that RealPage, Inc. and lessors of multifamily residential real estate, including us, conspired to artificially inflate the prices of multifamily residential real estate above competitive levels. 15 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.

For example, we are currently a defendant, among other companies, in 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 the prices of multifamily rents above competitive levels using RealPage's revenue management software in violation of state and federal antitrust laws. Similarly, another lawsuit alleging violations of the District of Columbia's antitrust laws has been filed by the District of Columbia against RealPage and a number of large apartment community owners and operators, including us. For more detail on these lawsuits, see Note 11 to the consolidated financial statements included in this Annual Report on Form 10-K. 15 15 15 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.
