Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms Equity Residential Established Markets includes Boston, New York, Washington, D.C., Seattle, San Francisco and Southern California (Los Angeles, Orange County and San Diego). Expansion Markets includes Denver, Atlanta, Dallas/Ft. Worth and Austin. FFO and Normalized FFO: Funds From Operations (“FFO”) – Nareit defines FFO (December 2018 White Paper) as net income (computed in accordance with GAAP), excluding gains or losses from sales and impairment write-downs of depreciable real estate and land when connected to the main business of a REIT, impairment write-downs of investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity and depreciation and amortization related to real estate. Adjustments for partially owned consolidated and unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. Expected FFO per share is calculated on a basis consistent with actual FFO per share and is considered an appropriate supplemental measure of expected operating performance when compared to expected EPS. The Company believes that FFO and FFO available to Common Shares and Units are helpful to investors as supplemental measures of the operating performance of a real estate company, because they are recognized measures of performance by the real estate industry and by excluding gains or losses from sales and impairment write-downs of depreciable real estate and excluding depreciation related to real estate (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO and FFO available to Common Shares and Units can help compare the operating performance of a company’s real estate between periods or as compared to different companies. Normalized Funds From Operations ( Normalized FFO or NFFO ) – Normalized FFO begins with FFO and excludes: • the impact of any expenses relating to non-operating real estate asset impairment; • pursuit cost write-offs; • gains and losses from early debt extinguishment and preferred share redemptions; • gains and losses from non-operating assets; and • other miscellaneous items. Expected Normalized FFO per share is calculated on a basis consistent with actual Normalized FFO per share and is considered an appropriate supplemental measure of expected operating performance when compared to expected EPS. The Company believes that Normalized FFO and Normalized FFO available to Common Shares and Units are helpful to investors as supplemental measures of the operating performance of a real estate company because they allow investors to compare the Company's operating performance to its performance in prior reporting periods and to the operating performance of other real estate companies without the effect of items that by their nature are not comparable from period to period and tend to obscure the Company's actual operating results. 17

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms Equity Residential FFO, FFO available to Common Shares and Units, Normalized FFO and Normalized FFO available to Common Shares and Units do not represent net income, net income available to Common Shares or net cash flows from operating activities in accordance with GAAP. Therefore, FFO, FFO available to Common Shares and Units, Normalized FFO and Normalized FFO available to Common Shares and Units should not be exclusively considered as alternatives to net income, net income available to Common Shares or net cash flows from operating activities as determined by GAAP or as a measure of liquidity. The Company's calculation of FFO, FFO available to Common Shares and Units, Normalized FFO and Normalized FFO available to Common Shares and Units may differ from other real estate companies due to, among other items, variations in cost capitalization policies for capital expenditures and, accordingly, may not be comparable to such other real estate companies. FFO available to Common Shares and Units and Normalized FFO available to Common Shares and Units are calculated on a basis consistent with net income available to Common Shares and reflects adjustments to net income for preferred distributions and premiums on redemption of preferred shares in accordance with GAAP. The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units are collectively referred to as the Noncontrolling Interests – Operating Partnership . Subject to certain restrictions, the Noncontrolling Interests – Operating Partnership may exchange their OP Units for Common Shares on a one-for-one basis. The following table presents reconciliations of EPS to FFO per share and Normalized FFO per share for Consolidated Statements of Funds From Operations and Normalized Funds From Operations.

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms Equity Residential Net Operating Income (“NOI”) – NOI is the Company’s primary financial measure for evaluating each of its apartment properties. NOI is defined as rental income less direct property operating expenses (including real estate taxes and insurance). The Company believes that NOI is helpful to investors as a supplemental measure of its operating performance because it is a direct measure of the actual operating results of the Company's apartment properties. NOI does not include an allocation of property management expenses either in the current or comparable periods.

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms AvalonBay Communities Commercial represents results attributable to the non-apartment components of the Company's mixed-use communities and other non-residential operations. Development is composed of consolidated communities that are either currently under construction or were under construction and were completed during the current year. These communities may be partially or fully complete and operating. Established Regions include markets located in New England, the New York/New Jersey Metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California. Expansion Regions include markets located in Raleigh-Durham and Charlotte, North Carolina, Southeast Florida, Dallas and Austin, Texas, and Denver, Colorado. Economic Occupancy is defined as total possible Residential revenue less vacancy loss as a percentage of total possible Residential revenue. Total possible Residential revenue (also known as “gross potential”) is determined by valuing occupied units at contract rates and vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant apartments at their Market Rents, Economic Occupancy takes into account the fact that apartment homes of different sizes and locations within a community have different economic impacts on a community’s gross revenue. FFO and Core FFO are generally considered by management to be appropriate supplemental measures of our operating and financial performance. FFO is calculated by the Company in accordance with the definition adopted by Nareit. FFO is calculated by the Company as Net income or loss attributable to common stockholders computed in accordance with GAAP, adjusted for gains or losses on sales of previously depreciated operating communities, cumulative effect of a change in accounting principle, impairment write-downs of depreciable real estate assets, write-downs of investments in affiliates due to a decrease in the value of depreciable real estate assets held by those affiliates and depreciation of real estate assets, including similar adjustments for unconsolidated partnerships and joint ventures, including those from a change in control. FFO can help one compare the operating and financial performance of a real estate company between periods or as compared to different companies because adjustments such as (i) gains or losses on sales of previously depreciated property or (ii) real estate depreciation may impact comparability between companies as the amount and timing of these or similar items can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates. Core FFO is the Company's FFO as adjusted for non-core items outlined in the table below. By further adjusting for items that we do not consider to be part of our core business operations, Core FFO can help with the comparison of core operating performance of the Company between periods. A reconciliation of Net income attributable to common stockholders to FFO and to Core FFO is as follows (dollars in thousands): 22

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms AvalonBay Communities Initial Stabilized Yield represents NOI as a percentage of Total Capital Cost for the first 12 months after Stabilized Operations and is weighted based on the Total Capital Cost of each community. Like-Term Effective Rent Change for an individual apartment home represents the percentage change in effective rent between two leases of the same lease term category for the same apartment. The Company defines effective rent as the contractual rent for an apartment less amortized concessions and discounts. Like-Term Effective Rent Change with respect to multiple apartment homes represents an average. New Move-In Like-Term Effective Rent Change is the change in effective rent between the contractual rent for a resident who moves out of an apartment, and the contractual rent for a resident who moves into the same apartment with the same lease term category. Renewal Like-Term Effective Rent Change is the change in effective rent between two consecutive leases of the same lease term category for the same resident occupying the same apartment. NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), property management and other indirect operating expenses, net of corporate income, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, loss on extinguishment of debt, net, general and administrative expense, income from unconsolidated investments, depreciation expense, income tax (benefit) expense, casualty loss, (gain) loss on sale of communities, other real estate activity and net operating income from real estate assets sold or held for sale. The Company considers NOI to be an important and appropriate supplemental performance measure to net income because it helps both investors and management to understand the core operations of a community or communities prior to the allocation of any corporate-level property management overhead or financing-related costs. NOI reflects the operating performance of a community and allows for an easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or group of assets. Projected NOI, as used within this presentation for certain Development communities and in calculating the Market Cap Rate for dispositions, represents management’s estimate, as of the date of this presentation (or as of the date of the buyer’s valuation in the case of dispositions), of projected stabilized rental revenue minus projected stabilized operating expenses. For Development communities, Projected NOI is calculated based on the first twelve months of Stabilized Operations following the completion of construction. In calculating the Market Cap Rate, Projected NOI for dispositions is calculated for the first twelve months following the date of the buyer’s valuation. Projected stabilized rental revenue represents management’s estimate of projected gross potential minus projected stabilized economic vacancy and adjusted for projected stabilized concessions plus projected stabilized other rental revenue. Projected stabilized operating expenses do not include interest, income taxes (if any), depreciation or amortization, or any allocation of corporate-level property management overhead or general and administrative costs. In addition, projected stabilized operating expenses for Development communities do not include property management fee expense. Projected gross potential for Development communities and dispositions is generally based on leased rents for occupied homes and management’s best estimate of rental levels for homes which are currently unleased, as well as those homes which will become available for lease during the twelve-month forward period used to develop Projected NOI. The weighted average Projected NOI as a percentage of Total Capital Cost is weighted based on the Company’s share of the Total Capital Cost of each community, based on its percentage ownership. 24

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms AvalonBay Communities Residential represents results attributable to the Company's apartment rental operations, including parking and other ancillary Residential revenue. Same Store is composed of consolidated communities where a comparison of operating results from the prior year to the current year is meaningful as these communities were owned and had Stabilized Operations, as defined below, as of the beginning of the respective prior year period. Therefore, for 2026 operating results, Same Store is composed of consolidated communities that have Stabilized Operations as of January 1, 2025, are not conducting or are not probable to conduct substantial redevelopment activities and are not held for sale or probable for disposition within the current year. Stabilized Operations is defined as operations of a community that occur after the earlier of (i) attainment of 90% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment. Suburban (locations) are defined as submarkets having less than 3,500 households per square mile. Total Capital Cost includes all capitalized costs projected to be or actually incurred to develop the respective Development or Redevelopment community, including land acquisition costs, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees, allocated development overhead and other regulatory fees and a contingency estimate, offset by proceeds from the sale of any associated land or improvements, all as determined in accordance with GAAP. Total Capital Cost also includes costs incurred related to first generation commercial tenants, such as tenant improvements and leasing commissions. For Redevelopment communities, Total Capital Cost excludes costs incurred prior to the start of redevelopment when indicated. With respect to communities where development or redevelopment was completed in a prior period or the current period, Total Capital Cost reflects the actual cost incurred, plus any contingency estimate made by management. Total Capital Cost for communities identified as having joint venture ownership, either during construction or upon construction completion, represents the total projected joint venture contribution amount. For joint ventures not in construction, Total Capital Cost is equal to gross real estate cost. Turnover is the annualized number of units turned over during the period, divided by the total number of apartment homes for the respective period, and excludes any third-party managed communities. Urban (locations) are defined as submarkets having 3,500 or more households per square mile. 25
