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, represents EBITDAre further adjusted for items that are not considered part of MAA’s core 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, casualty related (recoveries) charges, net, gain or loss on debt extinguishment, legal costs and settlements, net and COVID-19 related costs. 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 as an indicator of operating performance. Core Adjusted Funds from Operations (Core AFFO) Core AFFO is composed of Core FFO less recurring capital expenditures. Core AFFO should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. As an owner and operator of real estate, MAA considers Core AFFO to be an important measure of performance from operations because Core AFFO measures the ability to control revenues, expenses and recurring capital expenditures. Core Funds from Operations (Core FFO) Core FFO represents FFO as adjusted for items that are not considered part of MAA’s 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 (recoveries) charges, net, gain or loss on debt extinguishment, legal costs and settlements, net, COVID-19 related costs, mark-to-market debt adjustments and other non-core items. While MAA's definition of Core FFO may be similar to others in the industry, MAA’s methodology for calculating Core FFO may differ from that utilized by other REITs and, accordingly, may not be comparable to such other REITs. Core 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 Core FFO is helpful in understanding its 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. 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 as an indicator of operating 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 further adjusted for the gain or loss on sale of depreciable asset sales and 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 as an indicator of operating performance. Funds Available for Distribution (FAD) FAD is composed of Core FFO less total capital expenditures, excluding development spending, property acquisitions, capital expenditures relating to significant casualty losses that management expects to be reimbursed by insurance proceeds and corporate related capital expenditures. FAD should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. 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 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 gain or loss 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 net income attributable to noncontrolling interests 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. 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, Cash and cash equivalents and 1031(b) exchange proceeds included in Restricted cash. 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 and 1031(b) exchange proceeds included in Restricted cash. 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 and amortization, 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 is a helpful tool in evaluating operating performance because it measures the core operations of property performance by excluding corporate level expenses and other items not related to property operating performance. Non-Same Store and Other NOI Non-Same Store and Other NOI represents Rental and other property revenues less Total property operating expenses, excluding depreciation and amortization, for all properties classified within the Non-Same Store and Other Portfolio during the period. Non-Same Store and Other NOI includes all storm-related expenses related to hurricanes. Non-Same Store and Other NOI should not be considered as an alternative to Net income available for MAA common shareholders. MAA believes Non-Same Store and Other NOI is a helpful tool in evaluating operating performance because it measures the core operations of property performance by excluding corporate level expenses and other items not related to property operating performance. Same Store NOI Same Store NOI represents Rental and other property revenues less Total property operating expenses, excluding depreciation and amortization, for all properties classified within the Same Store Portfolio during the period. Same Store NOI excludes storm-related expenses related to hurricanes. 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 operating performance 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 an applicable 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 when achieving 90% average physical occupancy for 90 days. Non-Same Store and Other Portfolio Non-Same Store and Other Portfolio includes recently acquired communities, communities in development or lease-up, communities that have been disposed of or identified for disposition, communities that have experienced a significant casualty loss, stabilized communities that do not meet the requirements defined by the Same Store Portfolio, retail properties and commercial properties. Resident Turnover Resident turnover represents resident move outs excluding transfers within the Same Store Portfolio as a percentage of expiring leases on a rolling twelve month basis as of the end of the reported quarter. Same Store Portfolio MAA reviews its Same Store Portfolio at the beginning of each calendar year, or as significant transactions or events 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 when achieving 90% average physical 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 experienced a significant casualty loss are also excluded from the Same Store Portfolio.
