CAPITAL MARKETS UPDATE MAY 2018 2 FORWARD LOOKING STATEMENTS This presentation contains forward - looking statements within the meaning of Section 27 A of the Securities Act of 1933 , as amended, and Section 21 E 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 uncertainties 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 2018 operating results, expected benefits and synergies from the merger with Post Properties, Inc . and the timing of those benefits and synergies, the anticipated value of current development projects and lease - up communities, estimated costs of property development, 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 and incremental rent growth, 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 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 ; litigation and compliance costs associated with laws requiring access for disabled persons ; difficulty in integrating MAA’s and Post Properties’ merger ; 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 .

As an owner and operator of real estate, MAA considers Adjusted EBITDA re to be an important measure of performance from core operations because Adjusted EBITDA re does not include various income and expense items that are not indicative of operating performance. MAA's computation of Adjusted EBITDA re may differ from the methodology utilized by other companies to calculate Adjusted EBITDA re . Adjusted EBITDA re 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 w ith business goals, certain capital expenditures related to commercial properties have been reclassified out of recurring capital expenditures fo r c omparative purposes. AFFO should not be considered as an alternative to Net income available for MAA common shareholders. As an owner a nd operator of real estate, MAA considers AFFO to be an important measure of performance from operations because AFFO measures the ability t o c ontrol revenues, expenses and recurring capital expenditures. Same Store NOI Same Store NOI represents total operating revenues less total property operating expenses, excluding depreciation, for all propert ies classified within the Same Store Portfolio during the period. Same Store NOI should not be considered as an alternative to Net income av ail able for MAA common shareholders.

EBITDA For purposes of calculations in this release, Earnings Before Interest, Income Taxes, Depreciation and Amortization, or EBITDA, i s c omposed of net income plus depreciation and amortization, interest expense, and income taxes.

As an owner and operator of real estate, MAA considers EBITDA re to be an important measure of performance from core operations because EBITDA re does not include various expense items that are not indicative of operating performance. While MAA's definition of EBITDA re is in accordance with NAREIT's definition, it may differ from the methodology utilized by other companies to calculate EBITDA re . EBITDA re 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 consider s F AD to be an important measure of performance from core operations because FAD measures the ability to control revenues, expenses and tota l c apital expenditures. Funds From Operations (FFO) FFO represents net income available for MAA common shareholders (computed in accordance with U.S. generally accepted accounting p rin ciples, or GAAP) excluding extraordinary items, asset impairment, gains or losses on disposition of real estate assets, plus net inco me attributable to noncontrolling interest, depreciation and amortization of real estate assets, and adjustments for joint ventures to reflect FFO on the same ba sis. 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 the 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. 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 pe rfo rmance in that FFO excludes depreciation and amortization of real estate assets. MAA believes that GAAP historical cost depreciation of rea l e state assets is generally not correlated with changes in the value of those assets, whose value does not diminish predictably over time, as h ist orical cost depreciation implies. Gross Assets Gross Assets represents Total assets plus Accumulated depreciation and accumulated depreciation for Assets held for sale, whi ch is included in "Assets held for sale" on the Consolidated Balance Sheets.

Net Debt Net Debt represents Unsecured notes payable and Secured notes payable less Cash and cash equivalents and 1031(b) proceeds inc lud ed in "Restricted cash" on the Consolidated Balance Sheets. MAA believes Net Debt is a helpful tool in evaluating its debt positio n. Net Operating Income (NOI) Net Operating Income represents Rental and other property revenues less Total property operating expenses, excluding deprecia tio n, for all properties held during the period, regardless of their status as held for sale. NOI should not be considered as an alternativ e t o Net income available for MAA common shareholders. MAA believes NOI by market is a helpful tool in evaluating the operating performance wit hin MAA's markets because it measures the core operations of property performance by excluding corporate level expenses and other items no t related to property operating performance. Recurring Adjusted EBITDA re Recurring Adjusted EBITDA re represents Adjusted EBITDA re 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 EBITDA re is an important performance measure as it adjusts for certain items that by their nature are not comparable over periods and therefore tend t o o bscure actual operating performance. MAA's definition of Recurring Adjusted EBITDA re may differ from the methodology utilized by other companies to calculate Recurring Adjusted EBITDA re . Recurring Adjusted EBITDA re should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance.
