Form 10-K Summary . 48 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: • enhances investors’ understanding of MAA and the Operating Partnership by enabling investors to view the business as a whole in the same manner that management views and operates the business; • eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure in this report applies to both MAA and the Operating Partnership; and • creates time and cost efficiencies through the preparation of one combined report instead of two separate reports. 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. 1 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: • the consolidated financial statements in Item 8 of this report; • certain accompanying notes to the consolidated financial statements, including Note 2 - Earnings per Common Share of MAA and Note 3 - Earnings per OP Unit of MAALP; and Note 8 - Shareholders’ Equity of MAA and Note 9 - Partners’ Capital of MAALP; • the controls and procedures in Item 9A of this report; and • the certifications included as Exhibits 31 and 32 to this report. 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 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. 30 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 fi

This excerpt is only the cover page/header of Sleep Number’s Form 10-Q for the quarter ended April 4, 2026. It contains filing metadata (issuer, ticker, exchange, address) but no financial statements, MD&A, guidance, risks, or operational commentary. As a result, it is not directly actionable for trading beyond confirming the filing exists.

The provided excerpt is only the cover/filing header of SoundHound AI, Inc.’s 10‑Q for the quarter ended 2026‑03‑31. It contains listing/security identifiers (SOUN, SOUNW) but no financial statements, MD&A, guidance, risk updates, liquidity details, or material events. As a result, there is insufficient information to form high-confidence, actionable bullish/bearish theses beyond generic “company filed its 10‑Q” metadata.

The provided excerpt is only the boilerplate cover/filing-status section of Teucrium Commodity Trust’s Form 10‑Q for period ended 2026‑03‑31, with no portfolio holdings, performance, risk, or material updates included. As-is, it contains no actionable investment information beyond confirming the existence of the filing and the issuer/ticker identity (WEAT).

The provided text is only the cover/header portion of Archer Aviation’s Form 10‑Q for the quarter ended 2026‑03‑31 (issuer identity, exchange listing, and securities outstanding). It contains no operating/financial results, guidance, liquidity details, backlog, or risk-factor updates—so it is minimally actionable for trading beyond basic security identifiers and a generic dilution/optionality consideration from warrants.

This excerpt is essentially the cover page of CleanSpark, Inc.’s Form 10-Q for the quarter ended March 31, 2026. It contains identifiers (CIK/file no.), listing venue, and security descriptions (common stock and redeemable warrants with specific exercise terms), but no operating/financial results, guidance, risks, or MD&A detail. Actionability is therefore limited to capital-structure/dilution considerations around the listed warrant.

This excerpt of AST SpaceMobile’s 10‑Q is largely SEC cover-page/boilerplate (registrant info, exchange listing, filing compliance) and contains no financial results, guidance, liquidity, risk-factor updates, or operating metrics. As provided, it does not create a clear tradable catalyst beyond confirming continued reporting/listing status.

This excerpt only includes the cover page of Super Micro Computer, Inc.’s Form 10‑Q for the quarter ended March 31, 2026. It confirms the filing, issuer identity, listing (Nasdaq), and ticker (SMCI), but contains no financial results, guidance, risks, or MD&A content to support a directional investment view.
