Table of Contents EXPLANATORY NOTE This report combines the reports on Form 10-Q for the quarterly period ended March 31, 2024 of Equity Residential and ERP Operating Limited Partnership. Unless stated otherwise or the context otherwise requires, references to “EQR” mean Equity Residential, a Maryland real estate investment trust (“REIT”), and references to “ERPOP” mean ERP Operating Limited Partnership, an Illinois limited partnership. References to the “Company,” “we,” “us” or “our” mean collectively EQR, ERPOP and those entities/subsidiaries owned or controlled by EQR and/or ERPOP. References to the “Operating Partnership” mean collectively ERPOP and those entities/subsidiaries owned or controlled by ERPOP. The following chart illustrates the Company’s and the Operating Partnership’s corporate structure: EQR is the general partner of, and as of March 31, 2024 owned an approximate 97.0% ownership interest in, ERPOP. The remaining 3.0% interest is owned by limited partners. As the sole general partner of ERPOP, EQR has exclusive control of ERPOP’s day-to-day management. Management operates the Company and the Operating Partnership as one business. The management of EQR consists of the same members as the management of ERPOP. The Company is structured as an umbrella partnership REIT (“UPREIT”) and EQR contributes all net proceeds from its various equity offerings to ERPOP. In return for those contributions, EQR receives a number of OP Units (see definition below) in ERPOP equal to the number of Common Shares it has issued in the equity offering. The Company may acquire properties in transactions that include the issuance of OP Units as consideration for the acquired properties. Such transactions may, in certain circumstances, enable the sellers to defer in whole or in part, the recognition of taxable income or gain that might otherwise result from the sales. This is one of the reasons why the Company is structured in the manner shown above. Based on the terms of ERPOP’s partnership agreement, OP Units can be exchanged with Common Shares on a one-for-one basis because the Company maintains a one-for-one relationship between the OP Units of ERPOP issued to EQR and the outstanding Common Shares. The Company believes that combining the reports on Form 10-Q of EQR and ERPOP into this single report provides the following benefits: • enhances investors’ understanding of the Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business; • eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both the Company and the Operating Partnership; and • creates time and cost efficiencies through the preparation of one combined report instead of two separate reports. Table of Contents The Company believes it is important to understand the few differences between EQR and ERPOP in the context of how EQR and ERPOP operate as a consolidated company. All of the Company’s property ownership, development and related business operations are conducted through the Operating Partnership and EQR has no material assets or liabilities other than its investment in ERPOP. EQR’s primary function is acting as the general partner of ERPOP. EQR also issues equity from time to time, the net proceeds of which it is obligated to contribute to ERPOP. EQR does not have any indebtedness as all debt is incurred by the Operating Partnership. The Operating Partnership holds substantially all of the assets of the Company, including the Company’s ownership interests in its joint ventures. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity offerings by EQR (which are contributed to the capital of ERPOP in exchange for additional partnership interests in ERPOP (“OP Units”) (on a one-for-one Common Share per OP Unit basis) or additional preference units in ERPOP (on a one-for-one preferred share per preference unit basis)), the Operating Partnership generates all remaining capital required by the Company’s business. These sources include the Operating Partnership’s working capital, net cash provided by operating activities, borrowings under its revolving credit facility and/or commercial paper program, the issuance of secured and unsecured debt and partnership interests, and proceeds received from disposition of certain properties and joint venture interests. Shareholders’ equity, partners’ capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership. The limited partners of the Operating Partnership are accounted for as partners’ capital in the Operating Partnership’s financial statements and as noncontrolling interests in the Company’s financial statements. The noncontrolling interests in the Operating Partnership’s financial statements include the interests of unaffiliated partners in various consolidated partnerships. The noncontrolling interests in the Company’s financial statements include the same noncontrolling interests at the Operating Partnership level and limited partner OP Unit holders of the Operating Partnership. The differences between shareholders’ equity and partners’ capital result from differences in the equity issued at the Company and Operating Partnership levels. To help investors understand the differences between the Company and the Operating Partnership, this report provides separate consolidated financial statements for the Company and the Operating Partnership; a single set of consolidated notes to such financial statements that includes separate discussions of each entity’s debt, noncontrolling interests and shareholders’ equity or partners’ capital, as applicable; and a combined Management’s Discussion and Analysis of Financial Condition and Results of Operations section that includes discrete information related to each entity. This report also includes separate Part I, Item 4, Controls and Procedures , sections and separate Exhibits 31 and 32 certifications for each of the Company and the Operating Partnership in order to establish that the requisite certifications have been made and that the Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 U.S.C. §1350. In order to highlight the differences between the Company and the Operating Partnership, the separate sections in this report for the Company and the Operating Partnership specifically refer to the Company and the Operating Partnership. In the sections that combine disclosure of the Company and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of the Company. Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because the Company is one business and the Company operates that business through the Operating Partnership. As general partner with control of ERPOP, EQR consolidates ERPOP for financial reporting purposes, and EQR essentially has no assets or liabilities other than its investment in ERPOP. Therefore, the assets and liabilities of the Company and the Operating Partnership are the same on their respective financial statements. The separate discussions of the Company and the Operating Partnership in this report should be read in conjunction with each other to understand the results of the Company on a consolidated basis and how management operates the Company.

RESIDENTIAL ERP OPERATING LIMITED PARTNERSHIP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 1. Business Equity Residential (“EQR”) is an S&P 500 company focused on the acquisition, development and management of residential properties located in and around dynamic cities that attract affluent long-term renters, a business that is conducted on its behalf by ERP Operating Limited Partnership (“ERPOP”). EQR is a Maryland real estate investment trust (“REIT”) formed in March 1993 and ERPOP is an Illinois limited partnership formed in May 1993. References to the “Company,” “we,” “us” or “our” mean collectively EQR, ERPOP and those entities/subsidiaries owned or controlled by EQR and/or ERPOP. References to the “Operating Partnership” mean collectively ERPOP and those entities/subsidiaries owned or controlled by ERPOP. Unless otherwise indicated, the notes to consolidated financial statements apply to both the Company and the Operating Partnership. EQR is the general partner of, and as of March 31, 2024 owned an approximate 97.0 % ownership interest in, ERPOP. All of the Company’s property ownership, development and related business operations are conducted through the Operating Partnership and EQR has no material assets or liabilities other than its investment in ERPOP. EQR issues equity from time to time, the net proceeds of which it is obligated to contribute to ERPOP, but does not have any indebtedness as all debt is incurred by the Operating Partnership. The Operating Partnership holds substantially all of the assets of the Company, including the Company’s ownership interests in its joint ventures. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. As of March 31, 2024, the Company, directly or indirectly through investments in title holding entities, owned all or a portion of 299 properties located in 10 states and the District of Columbia consisting of 79,688 apartment units. The ownership breakdown includes (table does not include any uncompleted development properties): Properties Apartment Units Wholly Owned Properties 285 76,628 Partially Owned Properties – Consolidated 14 3,060 299 79,688 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) and certain reclassifications considered necessary for a fair presentation have been included. Operating results for the quarter ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The balance sheets at December 31, 2023 have been derived from the audited financial statements at that date but do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. For further information, including definitions of capitalized terms not defined herein, refer to the consolidated financial statements and footnotes thereto included in the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023 . 18 Table of Contents Income and Other Taxes EQR has elected to be taxed as a REIT. This, along with the nature of the operations of its operating properties, resulted in no provision for federal income taxes at the EQR level. In addition, ERPOP generally is not liable for federal income taxes as the partners recognize their allocable share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level. Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes. The Company has elected taxable REIT subsidiary (“TRS”) status for certain of its corporate subsidiaries and, as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses. Recent Accounting Pronouncements In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules that will require certain climate-related information in registration statements and annual reports. In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. The new rules include a requirement to disclose material climate-related risks, descriptions of board and management oversight and risk management activities, the material impacts of these risks on a registrant’s strategy, business model and outlook, and any material climate-related targets or goals, as well as material effects and costs of severe weather events and other natural conditions and greenhouse gas emissions. Prior to the stay of the new rules, they would have been effective for annual periods beginning January 1, 2025, except for the greenhouse gas emissions disclosures, which would have been effective for annual periods beginning January 1, 2026. The Company is currently evaluating the impact of the new rules on its disclosures. In December 2023, the Financial Accounting Standards Board (“FASB”) issued an amendment to the income tax standards which requires disclosure enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. The new standard will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact of adopting the standard on its consolidated results of operations and financial position. In November 2023, the FASB issued an amendment to the segment reporting standards which requires disclosure for each reportable segment, on an interim and annual basis, the significant expense categories and amounts that are regularly provided to the chief operating decision maker and included in each reported measure of a segment’s profit or loss. Additionally, it requires disclosure of the title and position of the individual or the name of the group or committee identified as the chief operating decision maker. The new standard will be effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025 on a retrospective basis. The Company is currently evaluating the impact of adopting the standard on its consolidated results of operations and financial position. In March 2020, the FASB issued an amendment to the reference rate reform standard which provides the option for a limited period of time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on contract modifications and hedge accounting. The new standard was effective for the Company upon issuance and elections could be made through December 31, 2024. The Company elected to apply the hedge accounting expedients and application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. 3. Equity, Capital and Other Interests The Company refers to “Common Shares” and “Units” (which refer to both OP Units and restricted units) as equity securities for EQR and “General Partner Units” and “Limited Partner Units” as equity securities for ERPOP. To provide a streamlined and more readable presentation of the disclosures for the Company and the Operating Partnership, several sections below refer to the respective terminology for each with the same financial information and separate sections are provided, where needed, to further distinguish any differences in financial information and terminology. 19 Table of Contents The following table presents the changes in the Company’s issued and outstanding Common Shares and Units for the quarters ended March 31, 2024 and 2023: 2024 2023 Common Shares Common Shares outstanding at January 1, 379,291,417 378,429,708 Common Shares Issued: Conversion of OP Units 7,967 144,567 Exercise of share options 82,742 173,249 Employee Share Purchase Plan (ESPP) 32,496 27,393 Restricted share grants, net 177,581 123,304 Common Shares Other: Repurchased and retired ( 652,452 ) — Common Shares outstanding at March 31, 378,939,751 378,898,221 Units Units outstanding at January 1, 11,581,306 12,429,737 Restricted unit grants, net 159,283 229,913 Conversion of OP Units to Common Shares ( 7,967 ) ( 144,567 ) Units outstanding at March 31, 11,732,622 12,515,083 Total Common Shares and Units outstanding at March 31, 390,672,373 391,413,304 Units Ownership Interest in Operating Partnership 3.0 % 3.2 % The following table presents the changes in the Operating Partnership’s issued and outstanding General Partner Units and Limited Partner Units for the quarters ended March 31, 2024 and 2023: 2024 2023 General and Limited Partner Units General and Limited Partner Units outstanding at January 1, 390,872,723 390,859,445 Issued to General Partner: Exercise of EQR share options 82,742 173,249 EQR’s Employee Share Purchase Plan (ESPP) 32,496 27,393 EQR’s restricted share grants, net 177,581 123,304 Issued to Limited Partners: Restricted unit grants, net 159,283 229,913 General Partner Other: OP Units repurchased and retired ( 652,452 ) — General and Limited Partner Units outstanding at March 31, 390,672,373 391,413,304 Limited Partner Units Limited Partner Units outstanding at January 1, 11,581,306 12,429,737 Limited Partner restricted unit grants, net 159,283 229,913 Conversion of Limited Partner OP Units to EQR Common Shares ( 7,967 ) ( 144,567 ) Limited Partner Units outstanding at March 31, 11,732,622 12,515,083 Limited Partner Units Ownership Interest in Operating Partnership 3.0 % 3.2 % The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units, are collectively referred to as the “Noncontrolling Interests – Operating Partnership” and “Limited Partners Capital,” respectively, for the Company and the Operating Partnership. Subject to certain exceptions (including the “book-up” requirements of restricted units), the Noncontrolling Interests – Operating Partnership/Limited Partners Capital may exchange their Units with EQR for Common Shares on a one-for-one basis. The carrying value of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital (including redeemable interests) is allocated based on the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total in proportion to the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total plus the total number of Common Shares/General Partner Units. Net income is allocated to the Noncontrolling Interests – Operating Partnership/Limited Partners Capital based on the weighted average ownership percentage during the period. The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Noncontrolling Interests – Operating Partnership/Limited Partners Capital requesting an exchange of their Noncontrolling Interests – Operating Partnership/Limited Partners Capital with EQR. Once the Operating Partnership elects not to redeem the Noncontrolling Interests – Operating Partnership/Limited Partners Capital for cash, EQR is obligated to deliver Common Shares to the exchanging holder of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital. 20 Table of Contents The Noncontrolling Interests – Operating Partnership/Limited Partners Capital are classified as either mezzanine equity or permanent equity. If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Noncontrolling Interests – Operating Partnership/Limited Partners Capital are differentiated and referred to as “Redeemable Noncontrolling Interests – Operating Partnership” and “Redeemable Limited Partners,” respectively. Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer’s control to deliver registered shares. Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet. The Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period. EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital that are classified in permanent equity at March 31, 2024 and December 31, 2023. The carrying value of the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners is allocated based on the number of Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners in proportion to the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total. Such percentage of the total carrying value of Units/Limited Partner Units which is ascribed to the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners is then adjusted to the greater of carrying value or fair market value as described above. As of March 31, 2024 and 2023, the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners have a redemption value of approximately $ 298.2 million and $ 323.6 million, respectively, which represents the value of Common Shares that would be issued in exchange for the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners. The following table presents the changes in the redemption value of the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners for the quarters ended March 31, 2024 and 2023, respectively (amounts in thousands): 2024 2023 Balance at January 1, $ 289,248 $ 318,273 Change in market value 8,815 5,946 Change in carrying value 156 ( 668 ) Balance at March 31, $ 298,219 $ 323,551 Net proceeds from EQR Common Share and Preferred Share (see definition below) offerings and proceeds from exercise of options for Common Shares are contributed by EQR to ERPOP. In return for those contributions, EQR receives a number of OP Units in ERPOP equal to the number of Common Shares it has issued in the equity offering (or in the case of a preferred equity offering, a number of preference units in ERPOP equal in number and having the same terms as the Preferred Shares issued in the equity offering). As a result, the net proceeds from Common Shares and Preferred Shares are allocated for the Company between shareholders’ equity and Noncontrolling Interests – Operating Partnership and for the Operating Partnership between General Partner’s Capital and Limited Partners Capital to account for the change in their respective percentage ownership of the underlying equity. The Company’s declaration of trust authorizes it to issue up to 100,000,000 preferred shares of beneficial interest, $ 0.01 par value per share (the “Preferred Shares”), with specific rights, preferences and other attributes as the Board of Trustees may determine, which may include preferences, powers and rights that are senior to the rights of holders of the Company’s Common Shares.

Other EQR and ERPOP currently have an active universal shelf registration statement for the issuance of equity and debt securities that automatically became effective upon filing with the SEC in May 2022 and expires in May 2025. Per the terms of ERPOP’s partnership agreement, EQR contributes the net proceeds of all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis) or preference units (on a one-for-one preferred share per preference unit basis). The Company has an At-The-Market (“ATM”) share offering program which allows EQR to issue Common Shares from time to time into the existing trading market at current market prices or through negotiated transactions, including under forward sale arrangements. The current program matures in May 2025 and gives us the authority to issue up t o 13.0 million shares, all of which remain available for issuance as of March 31, 2024. During the quarter ended March 31, 2024 , the Company repurchased and subsequently retired approximately $ 38.5 million ( 652,452 shares at a weighted average price per share of $ 58.95 ) of its Common Shares in the open market under its share repurchase program. Concurrent with these transactions, ERPOP repurchased and retired the same amount of OP Units previously issued to EQR.

Investments in Partially Owned Entities The Company has invested in various entities with unrelated third parties which are either consolidated or accounted for under the equity method of accounting (unconsolidated). Consolidated Variable Interest Entities (“VIEs”) In accordance with accounting standards for consolidation of VIEs, the Company consolidates ERPOP on EQR’s financial statements. As the sole general partner of ERPOP, EQR has exclusive control of ERPOP’s day-to-day management. The limited partners are not able to exercise substantive kick-out or participating rights. As a result, ERPOP qualifies as a VIE. EQR has a controlling financial interest in ERPOP and, thus, is ERPOP’s primary beneficiary. EQR has the power to direct the activities of ERPOP that most significantly impact ERPOP’s economic performance as well as the obligation to absorb losses or the right to receive benefits from ERPOP that could potentially be significant to ERPOP. The Company has various equity interests in certain joint ventures that have been deemed to be VIEs, and the Company is the VIEs’ primary beneficiary. As a result, the joint ventures are required to be consolidated on the Company’s financial statements.

Fair Value Measurements The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments on listed market prices and third-party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may seek to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments. The Company may also use derivatives to manage commodity prices in the daily operations of the business. A three-level valuation hierarchy exists for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: • Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The following table summarizes the inputs to the valuations for each type of fair value measurement: Fair Value Measurement Type Valuation Inputs Employee holdings (other than Common Shares) within the supplemental executive retirement plan (the “SERP”) Quoted market prices for identical assets. These holdings are included in other assets and other liabilities on the consolidated balance sheets. Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Quoted market price of Common Shares. Mortgage notes payable and private unsecured debt (including its commercial paper and line of credit, if applicable) Indicative rates provided by lenders of similar loans. Public unsecured notes Quoted market prices for each underlying issuance. Derivatives Readily observable market parameters such as forward yield curves and credit default swap data. The fair values of the Company’s financial instruments (other than mortgage notes payable, unsecured notes, commercial paper, line of credit and derivative instruments), including cash and cash equivalents and other financial instruments, approximate their carrying or contract value. The following table provides a summary of the carrying and fair values for the Company’s mortgage notes payable and unsecured debt (including its commercial paper and line of credit, if applicable) at March 31, 2024 and December 31, 2023, respectively (amounts in thousands): March 31, 2024 December 31, 2023 Carrying Value Estimated Fair Value (Level 2) Carrying Value Estimated Fair Value (Level 2) Mortgage notes payable, net $ 1,633,870 $ 1,498,775 $ 1,632,902 $ 1,509,706 Unsecured debt, net 5,575,859 5,100,252 5,757,548 5,346,488 Total debt, net $ 7,209,729 $ 6,599,027 $ 7,390,450 $ 6,856,194 27 Table of Contents The following tables provide a summary of the fair value measurements for each major category of assets and liabilities measured at fair value on a recurring basis and the location within the accompanying consolidated balance sheets at March 31, 2024 and December 31, 2023, respectively (amounts in thousands): Fair Value Measurements at Reporting Date Using Description Balance Sheet Location 3/31/2024 Quoted Prices in Active Markets for Identical Assets/Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Supplemental Executive Retirement Plan Other Assets $ 103,917 $ 103,917 $ — $ — Liabilities Supplemental Executive Retirement Plan Other Liabilities $ 103,917 $ 103,917 $ — $ — Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Mezzanine $ 298,219 $ — $ 298,219 $ — Fair Value Measurements at Reporting Date Using Description Balance Sheet Location 12/31/2023 Quoted Prices in Active Markets for Identical Assets/Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Supplemental Executive Retirement Plan Other Assets $ 108,478 $ 108,478 $ — $ — Liabilities Supplemental Executive Retirement Plan Other Liabilities $ 108,478 $ 108,478 $ — $ — Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Mezzanine $ 289,248 $ — $ 289,248 $ — The following tables provide a summary of the effect of cash flow hedges on the Company’s accompanying consolidated statements of operations and comprehensive income for the quarters ended March 31, 2024 and 2023, respectively (amounts in thousands): March 31, 2024 Type of Cash Flow Hedge Amount of Gain/(Loss) Recognized in OCI on Derivative Location of Gain/(Loss) Reclassified from Accumulated OCI into Income Amount of Gain/(Loss) Reclassified from Accumulated OCI into Income Derivatives designated as hedging instruments: Interest Rate Contracts: Forward Starting Swaps $ — Interest expense $ ( 610 ) Total $ — $ ( 610 ) March 31, 2023 Type of Cash Flow Hedge Amount of Gain/(Loss) Recognized in OCI on Derivative Location of Gain/(Loss) Reclassified from Accumulated OCI into Income Amount of Gain/(Loss) Reclassified from Accumulated OCI into Income Derivatives designated as hedging instruments: Interest Rate Contracts: Forward Starting Swaps $ ( 9,780 ) Interest expense $ ( 1,095 ) Total $ ( 9,780 ) $ ( 1,095 ) 28 Table of Contents As of March 31, 2024 and December 31, 2023 , there were approximately $ 6.3 million and $ 5.7 million in deferred gains, net, included in accumulated other comprehensive income (loss), respectively, related to previously settled and/or unsettled derivative instruments, of which an estimated $ 2.2 million may be recognized as additional interest expense during the twelve months ending March 31, 2025. Other The Company has invested in various equity securities without readily determinable fair values and has elected to measure them using the measurement alternative in accordance with the applicable accounting standards for equity securities. These investments are carried at cost less any impairment and adjusted to fair value if there are observable price changes for an identical or similar investment of the same issuer.

Contingencies Litigation and Legal Matters The Company, as an owner of real estate, is subject to various federal, state and local laws. Compliance by the Company with existing laws has not had a material adverse effect on the Company. However, the Company cannot predict the impact of new or 30 Table of Contents changed laws or regulations on its current properties or on properties that it may acquire in the future. The Company is involved in various pending and threatened legal proceedings which arise in the ordinary course of business. The Company evaluates these litigation matters on an ongoing basis, but in no event less than quarterly, in assessing the adequacy of its accruals and disclosures. For legal proceedings in which it has been determined that a loss is both probable and reasonably estimable, the Company records new accruals and/or adjusts existing accruals that represent its best estimate of the loss incurred based on the facts and circumstances known at that time. As of March 31, 2024 and December 31, 2023, the Company’s litigation accruals approximated $ 45.6 million and $ 17.1 million, respectively, and are included in other liabilities in the consolidated balance sheets. Actual losses may differ materially from the amounts noted above and the ultimate outcome of these legal proceedings is generally not yet determinable. As of March 31, 2024 and December 31, 2023, the Company does not believe there is any litigation pending or threatened against it that, either individually or in the aggregate and inclusive of the matters accrued for as noted above, may reasonably be expected to have a material adverse effect on the Company and its financial condition. The Company has been named as a defendant in a number of cases filed in late 2022 and 2023 alleging antitrust violations by RealPage, Inc., a seller of revenue management software products, and various owners and/or operators of multifamily housing, including us, that have utilized these products. The complaints allege collusion among the defendants to illegally fix and inflate the pricing of multifamily rents and seek monetary damages, injunctive relief, fees and costs. All of the cases except for one have been consolidated into a single putative class action in the United States District Court for the Middle District of Tennessee. On December 28, 2023, motions to dismiss this consolidated action, filed by RealPage, Inc. as well as us and our multifamily co-defendants, were denied by the Court and the case is proceeding. Another case with similar allegations has been filed by the District of Columbia against RealPage, Inc. and a number of multifamily owners and/or operators, including us. We believe these various lawsuits are without merit and we intend to vigorously defend against them. As these proceedings are in the early stages, it is not possible for the Company to predict the outcome nor is it possible to estimate the amount of loss, if any, which may be associated with an adverse decision in any of these cases. The Company is named as a defendant in a class action in the United States District Court for the Northern District of California filed in 2016 which alleges that the amount of late fees charged by the Company were improperly determined under California law. The plaintiffs are seeking monetary damages and other relief. On April 8, 2024, the Court issued certain findings of facts and conclusions of law that are adverse to the Company’s legal position. At this time, the Company is continuing to defend the action. While the resolution of this matter cannot be predicted with certainty, the Company does not believe that the eventual outcome will have a material adverse effect on the Company and its financial condition. 12. Reportable Segments Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the chief operating decision maker. The chief operating decision maker decides how resources are allocated and assesses performance on a recurring basis at least quarterly. The Company’s primary business is the acquisition, development and management of multifamily residential properties, which includes the generation of rental and other related income through the leasing of apartment units to residents. The chief operating decision maker evaluates the Company’s operating performance geographically by market and both on a same store and non-same store basis. While the Company does maintain a non-residential presence, it accounts for less than 5.0 % of total revenues for the quarter ended March 31, 2024 and is designed as an amenity for our residential residents. The chief operating decision maker evaluates the performance of each property on a consolidated residential and non-residential basis. The Company’s geographic consolidated same store operating segments represent its reportable segments. The Company’s development activities are other business activities that do not constitute an operating segment and as such, have been aggregated in the “Other” category in the tables presented below. All revenues are from external customers and there is no customer who contributed 10% or more of the Company’s total revenues during the quarters ended March 31, 2024 and 2023, respectively. The primary financial measure for the Company’s rental real estate segment is net operating income (“NOI”), which represents rental income less: 1) property and maintenance expense and 2) real estate taxes and insurance expense (all as reflected in the accompanying consolidated statements of operations and comprehensive income). 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. Revenues for all leases are reflected on a straight-line basis in accordance with GAAP for the current and comparable periods. 31 Table of Contents The following table presents a reconciliation of NOI from our rental real estate for the quarters ended March 31, 2024 and 2023, respectively (amounts in thousands): Quarter Ended March 31, 2024 2023 Rental income $ 730,818 $ 705,088 Property and maintenance expense ( 134,630 ) ( 137,579 ) Real estate taxes and insurance expense ( 108,927 ) ( 106,669 ) Total operating expenses ( 243,557 ) ( 244,248 ) Net operating income $ 487,261 $ 460,840 The following tables present NOI from our rental real estate for each segment for the quarters ended March 31, 2024 and 2023, respectively, as well as total assets and capital expenditures at March 31, 2024 (amounts in thousands): Quarter Ended March 31, 2024 Quarter Ended March 31, 2023 Rental Income Operating Expenses NOI Rental Income Operating Expenses NOI Same store (1) Los Angeles $ 119,267 $ 37,825 $ 81,442 $ 113,489 $ 37,311 $ 76,178 Orange County 31,101 6,927 24,174 29,372 6,694 22,678 San Diego 25,824 5,880 19,944 24,234 5,814 18,420 Subtotal - Southern California 176,192 50,632 125,560 167,095 49,819 117,276 Washington, D.C. 116,387 36,528 79,859 110,255 37,153 73,102 San Francisco 109,313 34,967 74,346 107,286 34,246 73,040 New York 123,964 51,275 72,689 118,045 49,488 68,557 Boston 80,451 23,738 56,713 76,878 24,163 52,715 Seattle 73,832 21,277 52,555 72,778 20,221 52,557 Denver 17,808 5,447 12,361 17,596 5,474 12,122 Other Expansion Markets 18,718 8,041 10,677 18,370 8,397 9,973 Total same store 716,665 231,905 484,760 688,303 228,961 459,342 Non-same store/other Non-same store (2) 12,948 6,092 6,856 4,903 2,860 2,043 Other (3) 1,205 5,560 ( 4,355 ) 11,882 12,427 ( 545 ) Total non-same store/other 14,153 11,652 2,501 16,785 15,287 1,498 Totals $ 730,818 $ 243,557 $ 487,261 $ 705,088 $ 244,248 $ 460,840 (1) For the quarters ended March 31, 2024 and 2023 , same store primarily includes all properties acquired or completed that were stabilized prior to January 1, 2023, less properties subsequently sold, which represented 77,373 apartment units.

Business Objectives and Operating and Investing Strategies The Company’s and the Operating Partnership’s overall business objectives and operating and investing strategies have not changed from the information included in the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023. 34 Table of Contents Results of Operations 2024 Transactions In conjunction with our business objectives and operating and investing strategies, the following table provides a rollforward of the transactions that occurred during the quarter ended March 31, 2024: Portfolio Rollforward ($ in thousands) Properties Apartment Units Sales Price Disposition Yield 12/31/2023 302 80,191 Dispositions: Consolidated Rental Properties (3 ) (504 ) $ (248,500 ) (5.5 %) Configuration Changes — 1 3/31/2024 299 79,688 Dispositions • The consolidated properties disposed of during the quarter ended March 31, 2024 were located in the Boston, Orange County and San Francisco markets and the sales generated an Unlevered IRR of 13.1%. Developments • The Company commenced construction on one consolidated apartment property during the quarter ended March 31, 2024, located in the Boston market, consisting of 440 apartment units totaling approximately $232.2 million of expected development costs; and • The Company spent approximately $31.4 million during the quarter ended March 31, 2024, primarily for consolidated and unconsolidated development projects. See Notes 4 and 5 in the Notes to Consolidated Financial Statements for additional discussion regarding the Company’s real estate investments and investments in partially owned entities. Comparison of the quarter ended March 31, 2024 to the quarter ended March 31, 2023 The following table presents a reconciliation of diluted earnings per share/unit for the quarter ended March 31, 2024 as compared to the same period in 2023: Quarter Ended March 31 Diluted earnings per share/unit for period ended 2023 $ 0.56 Property NOI 0.06 Corporate overhead (1) (0.01 ) Net gain/loss on property sales 0.22 Non-operating asset gains/losses 0.02 Depreciation expense (0.03 ) Other (0.05 ) Diluted earnings per share/unit for period ended 2024 $ 0.77 (1) Corporate overhead includes property management and general and administrative expenses. The Company’s primary financial measure for evaluating each of its apartment communities is net operating income (“NOI”). NOI represents 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. 35 Table of Contents The following tables present reconciliations of net income per the consolidated statements of operations to NOI, along with rental income, operating expenses and NOI per the consolidated statements of operations allocated between same store and non-same store/other results (amounts in thousands): Quarter Ended March 31, 2024 2023 $ Change % Change Net income $ 305,032 $ 220,071 $ 84,961 38.6 % Adjustments: Property management 35,458 31,466 3,992 12.7 % General and administrative 15,720 16,165 (445 ) (2.8 )% Depreciation 225,695 215,830 9,865 4.6 % Net (gain) loss on sales of real estate properties (188,185 ) (100,209 ) (87,976 ) 87.8 % Interest and other income (9,329 ) (1,538 ) (7,791 ) 506.6 % Other expenses 31,738 8,995 22,743 252.8 % Interest: Expense incurred, net 67,212 66,401 811 1.2 % Amortization of deferred financing costs 1,918 1,979 (61 ) (3.1 )% Income and other tax expense (benefit) 304 298 6 2.0 % (Income) loss from investments in unconsolidated entities 1,698 1,382 316 22.9 % Total NOI $ 487,261 $ 460,840 $ 26,421 5.7 % Rental income: Same store $ 716,665 $ 688,303 $ 28,362 4.1 % Non-same store/other 14,153 16,785 (2,632 ) (15.7 )% Total rental income 730,818 705,088 25,730 3.6 % Operating expenses: Same store 231,905 228,961 2,944 1.3 % Non-same store/other 11,652 15,287 (3,635 ) (23.8 )% Total operating expenses 243,557 244,248 (691 ) (0.3 )% NOI: Same store 484,760 459,342 25,418 5.5 % Non-same store/other 2,501 1,498 1,003 67.0 % Total NOI $ 487,261 $ 460,840 $ 26,421 5.7 % Note: See Note 12 in the Notes to Consolidated Financial Statements for detail by reportable segment/market. • The increase in same store rental income is primarily driven by healthy demand and modest supply across most of our markets. • The increase in same store operating expenses is due primarily to: • Real estate taxes – A $3.4 million increase due to escalation in rates and assessed values including an approximately 1.0% contribution to growth from 421-a tax abatement burnoffs in New York City. Once the burnoffs are completed, previously rent-restricted apartment units will transition to market; • Other on-site operating expenses – A $1.2 million increase primarily driven by higher property-related legal expenses; • Insurance – A $0.9 million increase due to higher premiums on property insurance renewal due to conditions in the insurance market that while less difficult than recent years, remain challenging; • Utilities – A $2.0 million decrease from electric primarily driven by lower commodity prices; and • Repairs and maintenance – A $0.7 million decrease due primarily to lower resident Turnover compared to the same period of 2023, moderation of previous wage/staffing pressures and a benefit from a relatively easy comparable period. • Non-same store/other NOI results consist primarily of properties acquired in calendar year 2023, operations from the Company’s development properties, other corporate operations and operations prior to disposition from 2023 and 2024 sold properties. • The increase in consolidated total NOI is primarily a result of the Company’s higher NOI from same store properties, largely due to improvement in same store revenues as noted above and the Company's continued focus on same store expense efficiency. See the Same Store Results section below for additional discussion of those results. See the reconciliation table of net income per the consolidated statements of operations to NOI above for the dollar and percentage changes related to the comparison discussions provided below. 36 Table of Contents Property management expenses include off-site expenses associated with the self-management of the Company’s properties as well as management fees paid to any third-party management companies. The increase during the quarter ended March 31, 2024 as compared to the prior year period is primarily attributable to increases in payroll-related costs, information technology expenses and legal and professional fees. General and administrative expenses, which include corporate operating expenses, decreased during the quarter ended March 31, 2024 as compared to the prior year period, primarily due to decreases in payroll-related costs, partially offset by increases in workforce/contractors costs. Depreciation expense, which includes depreciation on non-real estate assets, increased during the quarter ended March 31, 2024 as compared to the prior year period, primarily as a result of additional depreciation expense on properties acquired in 2023 and a development property placed in service during 2023, partially offset by lower depreciation from properties sold in 2023 and 2024. Net gain on sales of real estate properties increased during the quarter ended March 31, 2024 as compared to the prior year period, primarily as a result of the sale of three consolidated apartment properties for a higher gain in 2024 as compared to the sale of seven consolidated apartment properties in the same period in 2023. Interest and other income increased during the quarter ended March 31, 2024 as compared to the prior year period, primarily due to a net unrealized gain of $7.1 million on various investment securities as well as short-term investment income on cash and restricted deposit accounts due to a higher rate environment and higher overall invested balances, partially offset by decreases in insurance/litigation settlement proceeds received during 2023 as compared to 2024. Other expenses increased during the quarter ended March 31, 2024 as compared to the prior year period, primarily due to increases in litigation accruals, partially offset by decreases in data transformation project costs that occurred during 2023 but not during 2024. Interest expense, including amortization of deferred financing costs, increased during the quarter ended March 31, 2024, as compared to the prior year period, primarily due to higher rates on floating debt as compared to the prior year period. The effective interest cost on all indebtedness, excluding debt extinguishment costs/prepayment penalties, for the quarter ended March 31, 2024 was 3.89% as compared to 3.86% for the prior year period. The Company capitalized interest of approximately $3.1 million and $3.4 million during the quarters ended March 31, 2024 and 2023, respectively. Loss from investments in unconsolidated entities increased during the quarter ended March 31, 2024 as compared to the prior year period, primarily as a result of losses incurred on our unconsolidated development properties which recently started lease-up activities. Same Store Results Properties that the Company owned and were stabilized for all of both of the quarters ended March 31, 2024 and 2023 (the “First Quarter 2024 Same Store Properties”), which represented 77,373 apartment units, drove the Company’s results of operations. Properties are considered “stabilized” when they have achieved 90% occupancy for three consecutive months. Properties are included in same store when they are stabilized for all of the current and comparable periods presented. The following table provides comparative total same store results and statistics for the First Quarter 2024 Same Store Properties: First Quarter 2024 vs. First Quarter 2023 Same Store Results/Statistics Including 77,373 Same Store Apartment Units (includes Residential and Non-Residential) ($ in thousands except for Average Rental Rate) Results Statistics Description Revenues Expenses NOI Average Rental Rate Physical Occupancy Turnover Q1 2024 $ 716,665 $ 231,905 $ 484,760 $ 3,077 96.3 % 8.6 % Q1 2023 $ 688,303 $ 228,961 $ 459,342 $ 2,975 95.9 % 9.1 % Change $ 28,362 $ 2,944 $ 25,418 $ 102 0.4 % (0.5 %) Change 4.1 % (1) 1.3 % 5.5 % 3.4 % 37 Table of Contents Note: Same store revenues for all leases are reflected on a straight-line basis in accordance with GAAP for the current and comparable periods. (1) Non-Residential contributed 0.20% to quarterly same store revenue growth primarily due to improved collectibility expectations for certain Non-Residential tenants, resulting in the reinstatement of their respective straight-line receivable balances in the first quarter of 2024. The following table provides results and statistics related to our Residential same store operations for the quarters ended March 31, 2024 and 2023: First Quarter 2024 vs. First Quarter 2023 Same Store Residential Results/Statistics by Market Increase (Decrease) from Prior Year Markets/Metro Areas Apartment Units Q1 2024 % of Actual NOI Q1 2024 Average Rental Rate Q1 2024 Weighted Average Physical Occupancy % Q1 2024 Turnover Average Rental Rate Physical Occupancy Turnover Los Angeles 14,135 17.5 % $ 2,922 95.5 % 9.6 % 5.2 % 0.0 % (0.4 %) Orange County 3,718 5.2 % 2,900 96.1 % 7.4 % 5.9 % (0.1 %) (0.1 %) San Diego 2,878 4.3 % 3,103 96.1 % 8.0 % 5.7 % 0.7 % (1.7 %) Subtotal – Southern California 20,731 27.0 % 2,943 95.7 % 9.0 % 5.4 % 0.1 % (0.5 %) Washington, D.C. 14,716 16.9 % 2,665 97.1 % 7.0 % 5.0 % 0.5 % (0.4 %) San Francisco 11,345 15.8 % 3,281 96.4 % 9.5 % 1.2 % 0.7 % 0.1 % New York 8,536 14.1 % 4,592 97.0 % 6.5 % 3.7 % 0.2 % (1.0 %) Boston 7,077 11.0 % 3,557 95.7 % 7.4 % 4.6 % 0.2 % (0.6 %) Seattle 9,266 10.4 % 2,569 96.1 % 9.7 % (0.6 %) 1.0 % (1.4 %) Denver 2,505 2.6 % 2,415 96.3 % 10.1 % 1.6 % 0.0 % (1.0 %) Other Expansion Markets 3,197 2.2 % 1,973 95.5 % 13.3 % 0.1 % 0.6 % 0.9 % Total 77,373 100.0 % $ 3,077 96.3 % 8.6 % 3.4 % 0.4 % (0.5 %) Note: The above table reflects Residential same store results only. Residential operations account for approximately 96.0% of total revenues for the quarter ended March 31, 2024. During the quarter ended March 31, 2024, the Company had strong performance in its operating business, with healthy demand across all of our markets supported by a continuing solid job market and high employment for our target affluent renter demographic. Supply has also been modest in most of our existing coastal markets. As expected, our East Coast and Southern California markets performed better than San Francisco, Seattle and our expansion markets (Denver, Atlanta, Dallas/Ft. Worth and Austin). Key performance drivers thus far during 2024 included: • Pricing – Pricing (net of Leasing Concessions) improved seasonally and was generally consistent with expectations, with particular strength in New York and Washington, D.C., and improvement in San Francisco and Seattle. • Physical Occupancy – Physical Occupancy of 96.3% for the first quarter of 2024 was stronger than anticipated due to the low move-out activity discussed below. • Percentage of Residents Renewing and Turnover – The Percentage of Residents Renewing was high at 61.1% for the first quarter of 2024, which helped translate into the lowest quarterly same store Turnover in our history of 8.6%. We believe this reflects both the strength of demand and quality of our product and team. The Company continued to make progress in move-out activity related to delinquent residents during the quarter ended March 31, 2024, especially in our Los Angeles market, which put modest pressure on pricing and Physical Occupancy in that market. While the eviction process remains challenging and we have more progress to make in reducing delinquencies in our portfolio, we have made significant strides already and timeframes for processing evictions have recently improved. Overall, the fundamentals of our business remain healthy. Long-term, we expect elevated single family home ownership costs, positive household formation trends, manageable competitive new supply in our established coastal markets and the overall deficit in housing across the country to buffer the impact on our business from the risks of potential economic weakness. We also see our affluent resident base as being resilient to economic uncertainty, including elevated inflation, due to higher levels of disposable income and lower relative rent-to-income ratios. 38 Table of Contents Liquidity and Capital Resources With approximately $2.3 billion in readily available liquidity, a strong balance sheet, limited near-term debt maturities, very strong credit metrics and ample access to capital markets, the Company believes it is well positioned to meet its future obligations and take advantage of opportunities. See further discussion below. Statements of Cash Flows The following table sets forth our sources and uses of cash flows for the quarters ended March 31, 2024 and 2023 (amounts in thousands): Quarter Ended March 31, 2024 2023 Cash flows provided by (used for): Operating activities $ 421,031 $ 393,279 Investing activities $ 136,006 $ 43,723 Financing activities $ (500,472 ) $ (355,089 ) The following provides information regarding the Company’s cash flows from operating, investing and financing activities for the quarter ended March 31, 2024. Operating Activities Our operating cash flows are primarily impacted by NOI and its components, such as Average Rental Rates, Physical Occupancy levels and operating expenses related to our properties. Cash provided by operating activities for the quarter ended March 31, 2024 as compared to the prior year period, increased by approximately $27.8 million as a direct result of the NOI and other changes discussed above in Results of Operations . Investing Activities Our investing cash flows are primarily impacted by our transaction activity (acquisitions/dispositions), development spend and capital expenditures. For the quarter ended March 31, 2024, key drivers were: • Disposed of three consolidated rental properties, receiving net proceeds of approximately $247.3 million; • Invested $25.5 million primarily in consolidated development projects; • Invested $73.5 million in capital expenditures to real estate; and • Invested $7.8 million primarily in unconsolidated development joint venture entities as well as unconsolidated investments in real estate technology funds/companies for various technology initiatives. Financing Activities Our financing cash flows primarily relate to our borrowing activity (debt proceeds or repayment), distributions/dividends to shareholders/unitholders and other Common Share activity. For the quarter ended March 31, 2024, key drivers were: • Issued Common Shares related to share option exercises and ESPP purchases and received net proceeds of $6.0 million; • Paid dividends/distributions on Common Shares, Preferred Shares, Units (including OP Units and restricted units) and noncontrolling interests in partially owned properties totaling approximately $262.8 million; • Repurchased and retired 652,452 Common Shares, at a weighted average purchase price of $58.95 per share, for an aggregate purchased amount of approximately $38.5 million. See Note 3 in the Notes to Consolidated Financial Statements for further discussion; and • Repurchased and retired 402,500 Series K Preferred Shares/Preference Units with a liquidation value of approximately $20.1 million for total cash consideration of approximately $21.8 million, inclusive of premiums and accrued dividends through the redemption date. See Note 3 in the Notes to Consolidated Financial Statements for further discussion. 39 Table of Contents Short-Term Liquidity and Cash Proceeds The Company generally expects to meet its short-term liquidity requirements, including capital expenditures related to maintaining its existing properties and scheduled unsecured note and mortgage note repayments, through its working capital, net cash provided by operating activities and borrowings under the Company’s revolving credit facility and commercial paper program. Currently, the Company considers its cash provided by operating activities to be adequate to meet operating requirements and payments of distributions. The following table presents the Company’s balances for cash and cash equivalents, restricted deposits and the available borrowing capacity on its revolving credit facility as of March 31, 2024 and December 31, 2023 (amounts in thousands): March 31, 2024 December 31, 2023 Cash and cash equivalents $ 44,535 $ 50,743 Restricted deposits $ 152,025 $ 89,252 Unsecured revolving credit facility availability $ 2,270,562 $ 2,086,585 Credit Facility and Commercial Paper Program The Company has a $2.5 billion unsecured revolving credit facility maturing October 26, 2027. The Company has the ability to increase available borrowings by an additional $750.0 million by adding lenders to the facility, obtaining the agreement of existing lenders to increase their commitments or incurring one or more term loans. The interest rate on advances under the facility will generally be the Secured Overnight Financing Rate (“SOFR”) plus a spread (currently 0.715%), or based on bids received from the lending group, and the Company pays an annual facility fee (currently 0.125%). Both the spread and the facility fee are dependent on the Company’s senior unsecured credit rating and other terms and conditions per the agreement. See Note 8 in the Notes to Consolidated Financial Statements for additional discussion of the Company’s credit facility. The Company may borrow up to a maximum of $1.0 billion under its commercial paper program subject to market conditions. The notes will be sold under customary terms in the United States commercial paper note market and will rank pari passu with all of the Company’s other unsecured senior indebtedness. The Company limits its utilization of the revolving credit facility in order to maintain liquidity to support its $1.0 billion commercial paper program along with certain other obligations. The following table presents the availability on the Company’s unsecured revolving credit facility as of April 25, 2024 (amounts in thousands): April 25. 2024 Unsecured revolving credit facility commitment $ 2,500,000 Commercial paper balance outstanding (414,000 ) Unsecured revolving credit facility balance outstanding — Other restricted amounts (3,438 ) Unsecured revolving credit facility availability $ 2,082,562 Dividend Policy The Company declared a dividend/distribution for the first quarter of 2024 of $0.675 per share/unit, an annualized increase of 2.0% over the amount paid in 2023. All future dividends/distributions remain subject to the discretion of the Company’s Board of Trustees. Total dividends/distributions paid in April 2024 amounted to $263.6 million (excluding distributions on Partially Owned Properties), which consisted of certain distributions declared during the quarter ended March 31, 2024. 40 Table of Contents Long-Term Financing and Capital Needs The Company expects to meet its long-term liquidity requirements, such as lump sum unsecured note and mortgage debt maturities, property acquisitions and financing of development activities, through the issuance of secured and unsecured debt and equity securities (including additional OP Units), proceeds received from the disposition of certain properties and joint ventures, along with cash generated from operations after all distributions. The Company has a significant number of unencumbered properties available to secure additional mortgage borrowings should unsecured capital be unavailable or the cost of alternative sources of capital be too high. The value of and cash flow from these unencumbered properties are in excess of the requirements the Company must maintain in order to comply with covenants under its unsecured notes and line of credit. Of the $28.7 billion in investment in real estate on the Company’s balance sheet at March 31, 2024, $25.6 billion or 89.1% was unencumbered. However, there can be no assurances that these sources of capital will be available to the Company in the future on acceptable terms or otherwise. For additional details, see Item 1A, Risk Factors, of the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023. EQR issues equity and guarantees certain debt of the Operating Partnership from time to time. EQR does not have any indebtedness as all debt is incurred by the Operating Partnership.

Adjustments for partially owned consolidated and unconsolidated partnerships and joint ventures are calculated to reflect funds from operations on the same basis. (2) Normalized funds from operations (“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/preference unit redemptions; • gains and losses from non-operating assets; and • other miscellaneous items. 42 Table of Contents (3) The Company believes that FFO and FFO available to Common Shares and Units / 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 / Units can help compare the operating performance of a company’s real estate between periods or as compared to different companies. The Company also believes that Normalized FFO and Normalized FFO available to Common Shares and Units / 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. FFO, FFO available to Common Shares and Units / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / Units do not represent net income, net income available to Common Shares / Units or net cash flows from operating activities in accordance with GAAP. Therefore, FFO, FFO available to Common Shares and Units / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / Units should not be exclusively considered as alternatives to net income, net income available to Common Shares / Units 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 / Units, Normalized FFO and Normalized FFO available to Common Shares and Units / 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. (4) FFO available to Common Shares and Units / Units and Normalized FFO available to Common Shares and Units / Units are calculated on a basis consistent with net income available to Common Shares / Units and reflects adjustments to net income for preferred distributions and premiums on redemption of preferred shares/preference units 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. Item 3. Quantitative and Qualitat ive Disclosures About Market Risk The Company’s and the Operating Partnership’s market risk has not changed materially from the amounts and information reported in Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk , to the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023.

Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective to ensure that information required to be disclosed by the Operating Partnership in its Exchange Act filings is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. 43 Table of Contents (b) Changes in Internal Control over Financial Reporting: There were no changes to the internal control over financial reporting of the Operating Partnership identified in connection with the Operating Partnership’s evaluation referred to above that occurred during the first quarter of 2024 that have materially affected, or are reasonably likely to materially affect, the Operating Partnership’s internal control over financial reporting. PART II. OTHER INFORMATION Item 1. Lega l Proceedings Other than as disclosed below, there have been no changes to the legal proceedings discussed in Part I, Item 3 of the Company's and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2023. As of March 31, 2024, the Company does not believe there is any litigation pending or threatened against it that, either individually or in the aggregate, may reasonably be expected to have a material adverse effect on the Company and its financial condition. See Note 11 in the Notes to Consolidated Financial Statements for further discussion. The Company is named as a defendant in a class action in the United States District Court for the Northern District of California filed in 2016 which alleges that the amount of late fees charged by the Company were improperly determined under California law. The plaintiffs are seeking monetary damages and other relief. On April 8, 2024, the Court issued certain findings of facts and conclusions of law that are adverse to the Company’s legal position. At this time, the Company is continuing to defend the action. While the resolution of this matter cannot be predicted with certainty, the Company does not believe that the eventual outcome will have a material adverse effect on the Company and its financial condition. Item 1A. R isk Factors There have been no material changes to the risk factors that were discussed in Part I, Item 1A of the Company’s and the Operating Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023. Item 2. Unregistered Sales of Equi ty Securities and Use of Proceeds Unregistered Common Shares Issued in the Quarter Ended March 31, 2024 (Equity Residential) During the quarter ended March 31, 2024, EQR issued 7,967 Common Shares in exchange for 7,967 OP Units held by various limited partners of ERPOP. OP Units are generally exchangeable into Common Shares on a one-for-one basis or, at the option of ERPOP, the cash equivalent thereof, at any time one year after the date of issuance. These shares were either registered under the Securities Act of 1933, as amended (the “Securities Act”), or issued in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act and the rules and regulations promulgated thereunder, as these were transactions by an issuer not involving a public offering. In light of the manner of the sale and information obtained by EQR from the limited partners in connection with these transactions, EQR believes it may rely on these exemptions. 44 Table of Contents Common Shares Repurchased in the Quarter Ended March 31, 2024 The Company repurchased and retired the following Common Shares during the quarter ended March 31, 2024: Period Total Number of Common Shares Purchased (1) Weighted Average Price Paid Per Share (1), (2) Total Number of Common Shares Purchased as Part of Publicly Announced Plans or Programs (1) Maximum Number of Common Shares that May Yet Be Purchased Under the Plans or Programs (1), (3) January 1, 2024 - January 31, 2024 — $ — — 13,000,000 February 1, 2024 - February 29, 2024 652,452 $ 58.95 652,452 12,347,548 March 1, 2024 - March 31, 2024 — $ — — 12,347,548 Total 652,452 $ 58.95 652,452 (1) The Common Shares repurchased during the quarter ended March 31, 2024 represent Common Shares repurchased under the Company’s publicly announced share repurchase program approved by its Board of Trustees.
