FORWARD-LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements, which are based on current expectations, estimates and projections about the industry and markets in which MAA operates and beliefs of and assumptions made by MAA management, involve known and unknown risks, uncertainties and other factors that could significantly affect the financial results of MAA. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and variations of such words and similar expressions are intended to identify such forward-looking statements, which are not historical in nature. In this presentation, forward-looking statements include, but are not limited to, statements about forecasted operating results, anticipated revenue and expense growth, expected acquisition and disposition activity, the outlook for multifamily supply, the outlook for job growth, anticipated capital raising and financing activities, anticipated occupancy rates, anticipated lease pricing, estimated development funding, the anticipated timing of completion of current development projects and the stabilization of such projects, MAA’s future development projects, the anticipated stabilization of communities in lease-up, the anticipated scope of MAA’s future redevelopment activities and projected redevelopment costs, incremental rent growth and incremental revenue, anticipated dividends, interest rate and other economic expectations, and other information that is not historical. All statements that address operating performance, events or developments that MAA anticipates or expects will occur in the future are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although MAA believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, MAA can give no assurance that its expectations will be achieved, and therefore actual outcomes and results may differ materially from what is expressed, implied or forecasted in such forward-looking statements. Some of the factors that may affect outcomes and results include, but are not limited to: inability to generate sufficient cash flows due to market conditions, changes in supply and/or demand, competition, uninsured losses, changes in tax and housing laws, or other factors; exposure as a multifamily-focused REIT to risks inherent in investments in a single industry and sector; adverse changes in real estate markets; failure of new acquisitions to achieve anticipated results or be efficiently integrated; failure of development communities to be completed, if at all, within budget and on a timely basis or to lease-up as anticipated; unexpected capital needs; changes in operating costs, including real estate taxes, utilities and insurance costs; losses from catastrophes in excess of our insurance coverage; level and volatility of interest or capitalization rates or capital market conditions; the effect of any rating agency actions; inability to attract and retain qualified personnel; cyberliability or potential liability for breaches of our privacy or information security systems; adverse legislative or regulatory tax changes; adverse legal proceedings; compliance costs associated with laws requiring access for disabled persons; and those additional risks and factors discussed in reports filed with the Securities and Exchange Commission by MAA from time to time, including those discussed under the heading “Risk Factors” in MAA’s most recently filed Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. MAA undertakes no duty to update any forward-looking statements appearing in this presentation. REGULATION G This presentation contains certain non-GAAP financial measures within the meaning of the Securities Exchange Act of 1934, as amended. MAA’s definitions of these non-GAAP financial measures, among other terms, and reconciliations to the most directly comparable GAAP measures, can be found in the accompanying Appendix and under the “Financial Results” navigation tab on the “For Investors” page of MAA’s website at www.maac.com.

EXPECTED FFO/SHARE SUPPLY/DEMAND OPERATIONS 2019 unusual or non-cash items not expected to recur in 2020: $0.17 per Share through 9/30/19 YTD from the valuation of the preferred derivative ($0 assumed in Q4) $0.08 per Share of land gains through 9/30/19 YTD with an additional $0.02 per Share assumed in Q4 $0.03 per Share through 9/30/19 YTD of net non-cash gain on RETV ($0 assumed in Q4) $0.02 per Share through 9/30/19 YTD of casualty gains ($0 assumed in Q4) In total, for full year 2019 $0.32 per Share of unusual or non-cash items expected to be included in FFO/Share, implying normalized FFO/Share guidance of $6.18 per Share for 20191 New Supply: Supply has been elevated the last couple of years; capital availability and permitting suggest there is no reason to believe that changes anytime soon As of now, the supply picture for 2020 appears to look similar to 2019: elevated from historical levels but not materially accelerating or decelerating from 2019 deliveries Platform: Legacy MAA and Post are now fully synchronized on the operating platform – execution related to revenue management, property staffing levels, and other on-site operations are similar across the entire portfolio. Any remaining performance variances are market/sub-market driven and related to the level of supply being delivered into the market, which is still weighted more toward the A assets, (typically more urban), than B assets (typically more suburban)2: Job Growth: Job growth has been strong, particularly in the Sun Belt region of the country Expectations are that job growth will moderate some from the level seen in 2019 However, the expectation is that job growth in MAA’s footprint will still outperform the national average 9/30/2019 YTD Effective Rent Growth A to A+ Assets 3.0% B to B+ Assets 3.8% Turnover: Turnover has remained near record lows in 2019; it increased slightly from Q2 to Q3 of 2019 We expect some increase in turnover in 2020 An increase in turnover would impact vacancy loss and turn costs, and shift more of the leasing toward new leases and less on renewals Real Estate Taxes/Insurance: Our preliminary forecast for real estate taxes (>35% of operating expenses) is growth of 4.0% to 5.0% The 7/1/2019 renewal increase for insurance was approximately 12% and the current market continues to be favorable to insurers. MAA is considering a move to Core FFO guidance for 2020 to provide more meaningful comparisons 2020 Considerations 1 Based on the FFO per Share guidance at the midpoint, normalized FFO should not be considered as an alternative to Net income available for common shareholders; MAA believes that normalized FFO guidance is helpful in understanding forecasted operating performance; see Appendix for a reconciliation of normalized FFO per Share guidance to Net income available for common shareholders. 2 Average effective rent/unit for 3Q 2019 of higher than $1,300 for A to A+ and $1,300 or lower for B to B+ for total multifamily portfolio

Definitions of Non-GAAP Financial Measures Adjusted EBITDAre For purposes of calculations in this release, Adjusted Earnings Before Interest, Income Taxes, Depreciation and Amortization for real estate, or Adjusted EBITDAre, is composed of EBITDAre adjusted for net gain or loss on non-depreciable asset sales, insurance and other settlement proceeds and gain or loss on debt extinguishment. As an owner and operator of real estate, MAA considers Adjusted EBITDAre to be an important measure of performance from core operations because Adjusted EBITDAre does not include various income and expense items that are not indicative of operating performance. MAA's computation of Adjusted EBITDAre may differ from the methodology utilized by other companies to calculate Adjusted EBITDAre. Adjusted EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial performance.   Adjusted Funds From Operations (AFFO) AFFO is composed of FFO less recurring capital expenditures. In order to better align the classification of capital expenditures with business goals, certain capital expenditures related to commercial properties have been reclassified out of recurring capital expenditures and revenue enhancing capital expenditures for comparative purposes. AFFO should not be considered as an alternative to Net income available for MAA common shareholders. As an owner and operator of real estate, MAA considers AFFO to be an important measure of performance from operations because AFFO measures the ability to control revenues, expenses and recurring capital expenditures.   EBITDA For purposes of calculations in this release, Earnings Before Interest, Income Taxes, Depreciation and Amortization, or EBITDA, is composed of net income plus depreciation and amortization, interest expense, and income taxes. As an owner and operator of real estate, MAA considers EBITDA to be an important measure of performance from core operations because EBITDA does not include various expense items that are not indicative of operating performance. EBITDA should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial performance.   EBITDAre For purposes of calculations in this release, Earnings Before Interest, Income Taxes, Depreciation and Amortization for real estate, or EBITDAre, is composed of EBITDA, as defined above, excluding the gain or loss on sale of depreciable asset sales and plus adjustments to reflect MAA's share of EBITDAre of unconsolidated affiliates. As an owner and operator of real estate, MAA considers EBITDAre to be an important measure of performance from core operations because EBITDAre does not include various expense items that are not indicative of operating performance. While MAA's definition of EBITDAre is in accordance with NAREIT's definition, it may differ from the methodology utilized by other companies to calculate EBITDAre. EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial performance. Funds Available for Distribution (FAD) FAD is composed of FFO less total capital expenditures, excluding development spending and property acquisitions. FAD should not be considered as an alternative to Net income available for MAA common shareholders. As an owner and operator of real estate, MAA considers FAD to be an important measure of performance from core operations because FAD measures the ability to control revenues, expenses and total capital expenditures.

Definitions of Non-GAAP Financial Measures Funds From Operations (FFO) FFO represents net income available for MAA common shareholders (calculated in accordance with GAAP) excluding gains or losses on disposition of operating properties and asset impairment, plus depreciation and amortization of real estate assets, net income attributable to noncontrolling interests, and adjustments for joint ventures. Because noncontrolling interest is added back, FFO, when used in this document, represents FFO attributable to the Company. While MAA's definition of FFO is in accordance with NAREIT's definition, it may differ from the methodology for calculating FFO utilized by other companies and, accordingly, may not be comparable to such other companies. FFO should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. MAA believes that FFO is helpful in understanding operating performance in that FFO excludes depreciation and amortization of real estate assets. MAA believes 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. Gross Assets Gross Assets represents Total assets plus Accumulated depreciation and accumulated depreciation for Assets held for sale, which is included in Assets held for sale. MAA believes that Gross Assets can be used as a helpful tool in evaluating its balance sheet positions. MAA believes 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.   Gross Real Estate Assets Gross Real Estate Assets represents Real estate assets, net plus Accumulated depreciation, Assets held for sale, net, accumulated depreciation for Assets held for sale and Cash and cash equivalents. MAA believes that Gross Real Estate Assets can be used as a helpful tool in evaluating its balance sheet positions. MAA believes 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. Net Debt Net Debt represents Unsecured notes payable and Secured notes payable less Cash and cash equivalents. MAA believes Net Debt is a helpful tool in evaluating its debt position. Net Operating Income (NOI) Net Operating Income represents Rental and other property revenues less Total property operating expenses, excluding depreciation, for all properties held during the period, regardless of their status as held for sale. NOI should not be considered as an alternative to Net income available for MAA common shareholders. MAA believes NOI by market is a helpful tool in evaluating the operating performance within MAA's markets because it measures the core operations of property performance by excluding corporate level expenses and other items not related to property operating performance.

Definitions of Non-GAAP Financial Measures Recurring Adjusted EBITDAre Recurring Adjusted EBITDAre represents Adjusted EBITDAre further adjusted to exclude certain items that are not considered part of MAA's core business operations such as acquisition and merger and integration expenses. MAA believes Recurring Adjusted EBITDAre is an important performance measure as it adjusts for certain items that by their nature are not comparable over periods and therefore tend to obscure actual operating performance. MAA's definition of Recurring Adjusted EBITDAre may differ from the methodology utilized by other companies to calculate Recurring Adjusted EBITDAre. Recurring Adjusted EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. Same Store NOI Same Store NOI represents Rental and other property revenues less Total property operating expenses, excluding depreciation, for all properties classified within the Same Store Portfolio during the period. Same Store NOI should not be considered as an alternative to Net income available for MAA common shareholders. MAA believes Same Store NOI is a helpful tool in evaluating the operating performance within MAA's markets because it measures the core operations of property performance by excluding corporate level expenses and other items not related to property operating performance.

Definitions of Other Key Terms Average Effective Rent per Unit Average Effective Rent per Unit represents the average of gross rent amounts after the effect of leasing concessions for occupied units plus prevalent market rates asked for unoccupied units, divided by the total number of units. Leasing concessions represent discounts to the current market rate. MAA believes average effective rent is a helpful measurement in evaluating average pricing. It does not represent actual rental revenue collected per unit. Average Physical Occupancy Average Physical Occupancy represents the average of the daily physical occupancy for the respective period. Development Communities Communities remain identified as development until certificates of occupancy are obtained for all units under development. Once all units are delivered and available for occupancy, the community moves into the Lease-up Communities portfolio. Lease-up Communities New acquisitions acquired during lease-up and newly developed communities remain in the Lease-up Communities portfolio until stabilized. Communities are considered stabilized after achieving at least 90% occupancy for 90 days. Non-Same Store Portfolio Non-Same Store Portfolio includes recent acquisitions, communities that have been identified for disposition, communities that have undergone a significant casualty loss, and stabilized communities that do not meet the requirements defined by the Same Store Portfolio. Same Store Portfolio MAA reviews its Same Store Portfolio at the beginning of each calendar year, or as significant transactions warrant. Communities are generally added into the Same Store Portfolio if they were owned and stabilized at the beginning of the previous year. Communities are considered stabilized after achieving at least 90% occupancy for 90 days. Communities that have been approved by MAA's Board of Directors for disposition are excluded from the Same Store Portfolio. Communities that have undergone a significant casualty loss are also excluded from the Same Store Portfolio. Unencumbered NOI Unencumbered NOI represents NOI generated by unencumbered assets (as defined in MAALP's bond covenants).
