        <footnote id="F1">On June 15, 2023, the reporting person elected to receive a grant of Series 2023D restricted limited partnership interests (&quot;RUs&quot;) in ERP Operating Limited Partnership (the &quot;OP&quot;), the OP of Equity Residential (the &quot;Company&quot;), in connection with the Company's annual grant of long-term compensation for prospective service from the 2023 Annual Meeting of Shareholders to the 2024 Annual Meeting of Shareholders.</footnote>
        <footnote id="F2">RUs are a class of partnership interest that automatically convert into an equal number of limited partnership interests of the OP (&quot;OP Units&quot;) when the capital account related to the RUs reaches a specified target for federal income tax purposes (provided such target is reached within ten years of issuance).  Subject to the vesting requirements of the grant and certain other restrictions, OP Units are exchangeable by the holder for common shares of the Company on a one-for-one basis or the cash value of such shares, at the Company's option.  The RUs reflected in this report also include any OP Units into which such RUs automatically convert.</footnote>
        <footnote id="F3">The RUs are scheduled to vest on June 15, 2024.  In addition, the RUs (including any OP Units into which they may automatically convert) are subject to a holding restriction until June 15, 2025.</footnote>
