2024 Hig hlights |

In 2024, we continued our long track record of creating value through sound capital allocation, focused and proactive revenue generation and expense management while maintaining a conservative balance sheet and taking corporate responsibility into account.

| Capital Allocation* |  |
| • Acquired approximately $1.6 billion of operating properties that were on average five years old and sold approximately $975.6 million of operating properties that were on average 35 years old, continuing to advance our strategy of investing in our Expansion Markets and reducing exposure to older or lower returning assets in selected Established Markets, with approximately 10% of our assets (based on net operating income) now located in our Expansion Markets. Approximately $600.0 million of acquisitions were funded with fixed rate long-term debt (see "Financial" highlights below). These transactions resulted in minimal current period dilution and what we believe to be better long-term growth prospects for the Company. • Substantially completed construction on four projects located in our Expansion Markets of Dallas/Ft. Worth and Denver, totaling approximately $338.0 million of development costs. • Invested approximately $274.0 million in Capital Expenditures to Real Estate for Same Store Properties in 2024, approximately 45% of which was NOI-Enhancing and represented Renovation Expenditures for 3,353 same store apartment units in addition to sustainability and property-level technology spend. • Repurchased 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 in 2024. |  |

| Operational* |  |
| • Increased Same Store Net Operating Income by 3.1% year-over-year, which exceeded the range of our original guidance. • Reported a modest 2.9% increase in same store expenses for the full year of 2024, which was lower than the range of our original guidance and a smaller increase than in 2023, reflecting the Company’s continued success in managing controllable expenses as well as limited real estate tax growth. |  |

*See the Supplemental Appendix beginning on page 80 for definitions of capitalized terms.

2024 Highlights

| Financial |  |

| Sustainability/Corporate Responsibility |  |
| • Recognized for our commitment to sustainability with our inclusion in both the Dow Jones Sustainability World and North America Indices, the first residential REIT to receive this distinction and one of only four U.S. REITs to be included in both indices. • Received the National Association of Real Estate Investment Trust's (“Nareit”) Residential Sector Leader in the Light award, which recognizes REITs that demonstrate leadership in implementing sustainable investment and operating practices, good governance and transparency. • Recognized by Newsweek as one of America’s Most Responsible Companies for the sixth consecutive year. • Named one of Sustainalytics’ Top-Rated ESG Companies, recognized as Regional Top Rated for 2025. • Held our third annual Company-wide Community Giving Month in November 2024 during which our employees participated in 51 events across the country for a total of 1,575 service hours. Collectively, our employees volunteered and donated the equivalent of over 50,000 meals. |  |

Governance of the Company

## Board of Trustees

Our business and affairs are managed under the direction of the Board of Trustees. Members of the Board are kept informed of the Company’s business through discussions with the Chairman, the Lead Trustee, the Chief Executive Officer and other officers, by reviewing materials provided to them and by participating in meetings of the Board and its committees as well as through the tours and presentations described below. Board members have complete access to the Company’s management team and our independent registered public accounting firm.

The Board’s Role in Overseeing Corporate Strategy for Long-Term Value Creation

The Board is deeply involved in the development and oversight of the Company’s long-term strategy: to invest in apartment properties located in strategically targeted markets with the goal of generating consistent and superior risk-adjusted total returns by balancing current cash flow generation with long-term capital appreciation. The Board routinely engages with Company management on the components of this strategy, such as identification of markets, renter preferences, economic, regulatory and political risks, operating focus, use of technology, allocation of capital, employee engagement and the management of corporate responsibility risks and opportunities that affect the Company’s business and the communities within which the Company conducts business.

Market Visits and Trustee Education

To stay connected with local aspects of Company strategy, the Board typically conducts at least one of its regularly scheduled quarterly meetings each year in one of the Company’s markets. At these market-focused meetings, the Board visits apartment communities owned by the Company, with opportunities to engage with and receive presentations from local employees. The Board also tours the market in general to investigate market risk factors, including growth trends, employment levels, environmental, climate and resiliency factors, regulatory issues and other important aspects of Company strategy. The Board’s opportunity to engage with local employees also ensures that the Board remains deeply connected to the Company’s culture. The Board's 2024 market meeting was held in San Francisco, one of the Company's Established Markets. The trustees toured the Company's 340 Fremont and 855 Brannan properties and received presentations from local management on investment, operating and development conditions in the San Francisco market and from outside experts on economic and political conditions. The trustees also toured an office property and received a briefing on office conditions in order to gauge economic recovery in downtown San Francisco.

In addition to market visits, many regular quarterly Board meetings include educational briefings from management regarding a wide variety of strategic initiatives, ranging from technology initiatives and cybersecurity projects to investment policies, customer and marketing activities, human capital initiatives and more, and from outside subject matter experts regarding topics such as the political landscape and the regulatory environment.

The Company also provides an orientation program for new trustees, which includes an overview of duties and our corporate governance policies, opportunities to take tours of Company properties, as well as one-on-one sessions with each member of executive management on the Company’s strategy and industry.

Please see the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 13, 2025 for a detailed discussion of the Company’s strategy, aspects of which are reviewed by the Board at every quarterly meeting.

Board Leadership Structure

Since the Company’s initial public offering in 1993, we have separated the roles of Chairman of the Board and Chief Executive Officer. David J. Neithercut, our former Chief Executive Officer, has served as Chairman since May 2023. See page 20 for biographical information regarding Mr. Neithercut. As our Chairman, Mr. Neithercut

In 2024, the non-employee trustees held five executive sessions, and the independent trustees held one executive session.

While risk management is primarily the responsibility of management, the Board provides overall risk oversight, both directly and through its committees, to identify, assess and prioritize the major risks the Company faces and the policies and procedures for monitoring and controlling such risks. In addition, the Board reviews and sets certain strategies and policies related to risks overseen by the Board's committees on a day-to-day basis, including the Company's sustainability, talent management and cybersecurity strategies. Further, the Lead Trustee engages in consistent and regular communication with the CEO regarding the Board's risk oversight responsibilities.

Each of these committees also meets with and reviews material from management and internal audit (as applicable) and reports to the Board, thereby keeping the entire Board fully informed and in a position to administer its overall risk management oversight responsibilities. All committee materials from management are generally made available to all trustees, not just those who serve on the applicable committee, and all trustees are invited to attend all committee meetings. In addition, at regularly scheduled Board meetings, the Board reviews key matters relating to the Company’s finances, liquidity, operations and investment activity. Furthermore,

Governance of the Company

education sessions relating to risk management topics are regularly provided at the Board meetings by internal and/or external subject matter experts.

Cybersecurity

The Audit Committee oversees our annual enterprise risk management assessment, where we assess key risks within the Company, including security and technology risks and cybersecurity threats. The Audit Committee oversees our ongoing cybersecurity risk management efforts and regularly receives detailed reports from representatives of our IT Security Team addressing a wide range of related topics. At least annually, our IT leadership (and external cybersecurity experts if applicable) reviews key cybersecurity strategies and policies with the full Board, including risk assessments, mitigation strategies, areas of emerging risks, incidents and industry trends and other areas of importance.

Assessment of Board Performance and Board Processes

Recognizing the importance of a rigorous evaluation process to allow boards to assess their performance and identify and address any potential gaps in the boardroom, the Board conducts an annual assessment of the performance of the full Board, individual Board members and Board committees. The Chair of the Corporate Governance Committee, together with the Lead Trustee, are responsible for determining the appropriate means for the evaluation process, which takes place in advance of the annual consideration of trustee nominees.

For the 2024 assessment, the Corporate Governance Committee engaged an independent third party to conduct a confidential and in-depth interview with each of the trustees to solicit their feedback on Board and individual trustee performance. In addition, the independent third party sought and received feedback from members of the executive team on their interactions with the Board and individual trustees. Following that, the independent third party shared with each trustee individually his or her own evaluation and provided the full Board with feedback on the Board and its committees. The Board's annual evaluation process provides a way to track progress in certain areas targeted for improvement from year to year and to identify opportunities to enhance the Board’s and committees’ effectiveness. The assessments confirm whether the current Board leadership and structure continue to be optimal for the Company, affirm whether trustees have sufficient time to devote their attention to the Company notwithstanding their other commitments and are an important factor taken into account by the Corporate Governance Committee in making its recommendations to the Board regarding trustee nominees.

Management Development and Succession

The Board’s goal, through the oversight of the Compensation Committee, is to have an ongoing program for executive leadership development and succession. As reflected in the Company’s Corporate Governance Guidelines, the Compensation Committee discusses the CEO’s recommendations for management development and succession for the Company’s other executives. Additionally, the Compensation Committee oversees long range plans for management development and succession for the CEO.

The Board’s executive succession plan involves conducting regular talent reviews, creating profiles of ideal candidates and selecting potential successors expected to fit the needs of the Company over time. In implementing these plans, the Board believes that, at its core, succession planning: (i) is a board-driven, collaborative and continuous process; (ii) should take into account the Company’s long-term strategic goals; and (iii) involves building a talent-rich organization by attracting and developing the right people. Individuals who are identified as high potential leaders are given exposure and visibility to Board members through formal presentations and informal events.

Governance of the Company

Furthermore, for 2024, all of our executives’ performance assessments for purposes of compensation included development or succession planning-related factors. 25% of the assessment of the CEO’s annual performance and 10% of the assessment of the other executives’ annual performance were based on individual goals (“Individual Goals”) that include development, succession or leadership-oriented goals. In addition to their review of executive development and succession, the Board is regularly updated on key talent indicators for the overall workforce, including development programs.

The long-term employees who now comprise our executive team were identified through this process and given exposure and visibility to the Board over many years, followed by a smooth transition period assisted by their retiring and/or transitioning predecessors. The Board was intensively involved in evaluating each of these executives prior to their promotions and had an extensive opportunity to observe each executive through presentations they gave to the Board and its committees as well as through significant informal contact.

Certain Relationships and Related Transactions

The Company has adopted a Code of Ethics and Business Conduct that applies to all trustees and employees. The purpose of the Code of Ethics and Business Conduct is to promote: (i) honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; (ii) full, fair, accurate, timely and understandable disclosure in periodic reports required to be filed by the Company; and (iii) compliance with all applicable rules and regulations that apply to the Company and its officers, employees and trustees. The Audit Committee has responsibility for reviewing the Company’s written policies relating to the avoidance of conflicts of interest and reviewing any proposed related party transactions.

Trustee Resignation Policies

The Company has a majority vote standard for the election of trustees in uncontested elections with a trustee resignation policy which requires that any trustee nominee who is not elected by a majority of votes cast must promptly tender his or her resignation to the Board. The Board would then decide within 90 days following certification of the shareholder vote, through a process managed by the Corporate Governance Committee and excluding the nominee in question, whether to accept or reject the tendered resignation, or whether other action is recommended. The Board would promptly publicly disclose its decision and rationale.

The Board has adopted a policy that requires each non-employee trustee to submit an offer of resignation from the Board upon a material change in employment or responsibilities. The Corporate Governance Committee has responsibility for assessing whether such change would impair the trustee’s ability to continue to serve effectively on the Board and recommending whether any such offer should be accepted by the Board.

## Share Ownersh ip Guidelines

In keeping with its belief that aligning the financial interests of the Company’s executives and trustees with those of the shareholders will result in enhanced shareholder value, the Board has established the following executive and trustee share ownership guidelines:

Position |  | Minimum Share Ownership
Trustees |  | 5x cash retainer
CEO |  | 6x base salary
Executive Vice Presidents |  | 3x base salary
Senior Vice Presidents |  | 1x base salary

Executives and trustees have five years from appointment or promotion to comply with the ownership requirements. In 2024, all of our trustees, executives and senior officers had met their respective share ownership requirements or were in the permitted time frame to achieve such ownership.

Equity Residential | 13 | 2025 Proxy Statement

Governance of the Company

The following equity interests count toward fulfillment of the ownership guidelines:

•
Company shares, including restricted shares; and
•
Partnership interests in ERP Operating Limited Partnership (the “Operating Partnership”), the Company's operating partnership (i.e., OP Units and restricted units).

Restricted units are partnership interests that are convertible on a one-for-one basis into OP Units subject to certain vesting and other tax restrictions. Restricted shares and restricted units are collectively referred to in this Proxy Statement as “Share Awards.”

## Securities Trading Policy and Prohibition against Hedging and Pledging of Company Equity Securities

The Company’s Securities Trading Policy sets forth guidelines and restrictions applicable to trustees and employees of the Company regarding transactions involving Company equity securities that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations and the exchange listing standards applicable to us. Pursuant to this policy, the Company imposes a trading moratorium on all trustees and officers at a vice president level and above in advance of earnings releases, and otherwise trustees and all employees are restricted from trading whenever they have knowledge of material non-public information such as material transactions or significant cybersecurity incidents. Among other things, this policy prohibits our trustees and executives from selling any Company equity securities if the security is not owned by the individual at the time of sale (commonly called a "short sale"). This policy further prohibits trustees and employees from (i) purchasing financial instruments that are designed to hedge or offset any decrease in the market value of their Company equity securities, (ii) engaging in short-term speculation in Company securities or (iii) engaging in any transaction in which he or she profits if the value of Company securities falls. In addition, this policy prohibits trustees and executives from holding Company securities in a margin account or pledging Company securities as collateral for a loan. The policy is available on the Company’s website at www.equityapartments.com in the Investor section under “Corporate Governance.”

## Political Contribu tions Policy

The Company has a robust policy governing political expenditures. Under the policy approved by the Board, any political spending by the Company must be legitimately linked to the Company’s business purposes and strategic intent, approved by the Chief Executive Officer, and reviewed annually by the Corporate Governance Committee. The policy, together with a disclosure on the amount spent under the policy during the previous calendar year, is available on the Company’s website at www.equityapartments.com in the Investor section under “Corporate Governance.”

## Shareholder Ri ght to Amend Bylaws

In response to a shareholder proposal and following significant engagement with shareholders holding more than 50% of the Company’s outstanding shares in the aggregate, Article XIV of the Company’s Bylaws was amended in 2017 to permit shareholders to amend the Bylaws by the affirmative vote of the holders of a majority of the outstanding common shares of the Company pursuant to a proposal submitted for approval at a duly called annual meeting or special meeting of shareholders by a shareholder, or group of up to five shareholders, owning 1% or more of the Company’s outstanding common shares continuously for at least one year. A shareholder proposal submitted under Article XIV may not alter or repeal (i) Article XII of the Bylaws, which provides for indemnification of trustees and officers of the Company or (ii) Article XIV of the Bylaws, which addresses procedures for amendment of the Bylaws, without the approval of the Board. The foregoing is a summary of Article XIV of the Company’s Bylaws and is qualified in its entirety by the text of that section. Since the adoption of the aforementioned amendment to Article XIV of the Company’s Bylaws, the trustees serving on the Board’s

Corporate Governance Committee have received an average voting approval percentage of nearly 97%, which the Company believes is an indication of its shareholders’ overwhelming support for this provision.

## Shareholder Engagement

The Company views shareholder engagement as a continuous process, with members of the management team and in some cases members of the Board periodically conducting extensive outreach to shareholders. In February 2025, we held an Investor Day in New York where we showcased our portfolio optimization strategy, innovative operations platform, strong culture, disciplined balance sheet management and longer-term return prospects and at which more than 80 investors and analysts participated in the event in person, with an additional 115 participating via webcast. Over the last twelve months, we spoke with investors who collectively held nearly 40% of our shares (or approximately 60% of shares held by non-indexed investors) and reached out to many more. At these one-on-one investor meetings, the management team updated investors on a range of topics and also gained an understanding of the perspectives and concerns of each investor. The Board and management team carefully consider the feedback from these meetings when evaluating our investment strategy as well as our corporate responsibility and executive compensation disclosures and practices, among other items.

## Board Composition and Trus tee Nomination Procedures

Trustee Qualifications

The Company’s Corporate Governance Guidelines set forth the Board’s policies for the desired attributes of trustees and the Board as a whole. The Board will seek to ensure that a substantial majority of its members are independent within the NYSE listing standards. Each member of the Board must possess the individual qualities of integrity and accountability, informed judgment, financial literacy and high performance standards and must be committed to representing the long-term interests of the Company and its shareholders.

The Board values diversity in its broadest sense, reflecting, but not limited to, diversity by profession, geography, gender, ethnicity, skills and experience, and believes that as a group, the nominees bring a deep range of thought and perspectives to the Board’s deliberations that improves decision-making, risk oversight and innovation. As a general matter, the Board does not believe it should create a mandatory retirement age for trustees or establish term limits for trustee service, instead preferring to rely upon its evaluation procedures as the primary method of ensuring that each trustee continues to act in a manner consistent with the best interests of the Company and its shareholders.

Identifying and Evaluating Nominees

The Corporate Governance Committee regularly assesses the appropriate number of trustees comprising the Board, and whether any vacancies on the Board are expected due to retirement or otherwise. The Corporate Governance Committee considers suggestions of potential trustee candidates made by current Board members, shareholders, professional search firms or other persons. Occasionally the Corporate Governance Committee will conduct searches through professional search firms, and in 2023, a retained third party search firm identified potential trustee candidates, resulting in one of the new trustee appointments in March 2024.

The Corporate Governance Committee considers those factors it deems appropriate in evaluating trustee candidates, which include judgment, strength of character, familiarity with businesses and organizations comparable in size or scope to the Company, breadth of experience and skill relative to other Board members and specialized knowledge or expertise. The evaluation also includes a critical review of annual performance assessments, as previously described. Furthermore, as also described above, the evaluation includes a review of whether trustee candidates have time available to devote to Board service. Of particular importance to the Company’s strategy are skills and experience relating to real estate; finance and capital markets; innovation, technology and cybersecurity risks; marketing and consumer insight; risk management; corporate responsibility; political and reputational risk; and corporate leadership in general.

Governance of the Company

Each of the members of the Corporate Governance Committee, as well as all or substantially all of the other trustees, including the Chief Executive Officer, interview potential candidates that the Corporate Governance Committee has deemed qualified and appropriate. If the Corporate Governance Committee determines that a potential candidate meets the needs of the Board, and has the qualifications as set forth in the Company’s Corporate Governance Guidelines, it will recommend the nomination of the candidate to the Board.

Shareholder Nominees

The Corporate Governance Committee will consider properly submitted shareholder nominees for election to the Board and will apply the same evaluation criteria in considering such nominees as it would to persons nominated under any other circumstance. A shareholder wishing to submit to the Corporate Governance Committee a potential nominee for election to the Board for its consideration should follow the following procedures:

Pursuant to the Company’s Bylaws, a shareholder of the Company who is a shareholder of record at the record date set by the Board for the purpose of determining shareholders entitled to vote at the annual meeting, at the time of giving notice (as described in this paragraph) and at the time of the annual meeting, and who is entitled to vote at such meeting, may nominate individuals for election to the Board if the shareholder complies with the following requirements. First, the shareholder must give the Corporate Secretary of the Company timely written notice of nomination. Generally, notice will be timely if it is delivered not earlier than the 150th day, nor later than 5:00 p.m., Central Time, on the 120th day, prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting. Accordingly, for the Company’s annual meeting in the year 2026, the Corporate Secretary must receive the notice not earlier than November 16, 2025 and not later than 5:00 p.m., Central Time, on December 16, 2025. The notice must set forth certain information as to each individual the shareholder proposes to nominate, information with respect to Company security ownership by the shareholder giving such notice, and, to the extent known by the shareholder giving notice, the name and address of any other shareholder supporting the nominee for election. The foregoing is a summary of Article II, Section 13 of the Bylaws of the Company and is qualified in its entirety by the text of that section. Shareholders who intend to solicit proxies in support of trustee nominees other than the Company's nominees must also comply with the additional requirements of Rule 14a-19(b) of the Securities Exchange Act of 1934 (the "Exchange Act").

The Company’s shareholders also possess the right to nominate candidates to the Board through proxy access provisions of the Company’s Bylaws. The Bylaws permit a shareholder, or group of up to 20 shareholders, owning 3% or more of the Company’s outstanding common shares continuously for at least three years, to include in the Company’s annual meeting proxy materials trustee nominations for up to 20% of the seats on the Board, subject to the other terms and conditions of the Bylaws. The foregoing is a summary of Article II, Section 16 of the Bylaws of the Company and is qualified in its entirety by the text of that section. Electronic copies of the Bylaws are available on the Company’s website at www.equityapartments.com in the Investor section under “Corporate Governance,” and hard copies are available free of charge by writing to Equity Residential, Two North Riverside Plaza, Suite 500, Chicago, Illinois 60606, Attn: Corporate Secretary or by contacting Investor Relations by phone (1-888-879-6356) or e-mail (investorrelations@eqr.com).

Board Refreshment

The Corporate Governance Committee seeks to maintain a board that as a whole possesses the independence, objectivity and mix of skills and experience to provide comprehensive and effective oversight of the Company’s strategic, operational and compliance risks. The Committee believes that succession planning and ongoing board refreshment are important to maintain an appropriate mix of skills and provide fresh perspectives while leveraging the institutional knowledge and historical perspective of the Board’s longer-tenured trustees. In keeping with the Committee's overall strategy for trustee succession and refreshment, since 2015 the Board has added seven new independent trustees in place of nine trustees who departed the Board due to retirement or death (including one trustee retiring in June of this year).

# Compensation Dis cussion and Analysis |

This Compensation Discussion and Analysis (“CD&A”) provides a detailed description of our executive compensation philosophy, objectives and components, the compensation decisions made under those components, and the performance metrics and other relevant factors the Compensation Committee used in making those decisions.

At our 2024 Annual Meeting of Shareholders, our 2023 Executive Compensation Program was approved by approximately 90% of the votes cast on the matter. Furthermore, since our current compensation structure was put in place in 2015 following significant shareholder outreach, our shareholders have approved it annually by an average of 93% of the votes cast and never with less than 90% support. We believe our shareholders’ overwhelming support for the Company’s compensation program reflects the strong alignment between executive pay and performance.

The Company’s 2024 Executive Compensation Program, which applied to Mr. Parrell and his direct reports, is based on a strong performance-oriented compensation philosophy to align executive and shareholder interests and is designed to attract, retain and motivate talented executives.

What We Do |  Do engage an independent compensation consultant to advise the Compensation Committee, which is comprised solely of independent trustees  Do have a strong pay for performance compensation philosophy with 91% of Chief Executive Officer pay and an average of 83% of other NEO pay tied solely to performance  Do require our Annual Incentive Plan to be primarily subject to objective performance metrics that align with the Company’s business strategy and the long-term interests of our shareholders  Do enhance executive retention with time-based, multi-year vesting schedules for equity incentive awards  Do align the long-term interests of our executives with those of our shareholders by awarding a significant percentage of compensation in the form of Long-Term Incentive Plan Awards, which are subject to quantitative performance metrics with three-year forward-looking performance periods  Do have meaningful share ownership guidelines for our executives and trustees  Do have a clawback policy for incentive-based executive compensation  Do have double-trigger vesting provisions in the event of a change in control under the Share Incentive Plan  Do include corporate responsibility-related goals in determining executive compensation

What We Don’t Do | X No employment agreements with any of our executives X No compensation incentives that encourage excessive risk taking X No repricing of Option Awards allowed X No hedging of Company shares allowed X No pledging of Company shares allowed by executives or trustees X No excise tax gross-ups in any new change in control agreements X No excessive perks to our executives

Compensation Discussion and Analysis

## Executive Compen sation Program

The Company’s Executive Compensation Program consists of three components: Annual Salary, Annual Incentive Plan and Long-Term Incentive Plan.

Annual Salary

For 2024, annual salaries of executives, the first component of the program, were set at levels competitive with other large companies engaged in the real estate industry with which the Company competes for executive talent. As it does annually, the Compensation Committee reviewed base salaries for the executives to determine whether any adjustments were necessary to reflect market conditions or changes in responsibilities.

Annual Incentive Plan

The second component of the program in 2024 was an Annual Incentive Plan, which allowed the executive to earn from 0% to 200% of target annual incentive by performance against pre-defined and pre-weighted annual goals (75% of which were objective measurable metrics for Mr. Parrell and 65% of which were objective measurable metrics for the other executives) established by the Compensation Committee. The goals were comprised of Corporate Goals, which were shared by all executives, and business unit goals (“Business Unit Goals”) for all executives other than Mr. Parrell, which were unique to each executive. These goals were pre-established, with all Corporate Goals and many Business Unit Goals measured objectively. In determining where to set Threshold, Target and Maximum performance levels for each Corporate Goal, the Compensation Committee set the Maximum levels to require higher performance relative to Target compared to the difference in performance between Target and Threshold. In other words, the Maximum level is a stretch goal, which is harder to achieve on a relative basis.

Individual Goals for each executive were pre-established by Mr. Parrell and approved by the Compensation Committee. Individual Goals were assessed subjectively and were intended to move the Company and/or business unit forward in terms of organizational structure, improve on such practices as enterprise-wide innovative thinking and the advancement of technology, data and analytics in the business, provide for appropriate leadership and succession management or otherwise address developmental needs of individuals or groups within the organization.

The Annual Incentive Plan rewarded achievement of these goals based on the Compensation Committee’s quantitative and qualitative assessment of the executives’ contributions to that performance. Performance against each goal was assessed against Threshold, Target and Maximum performance levels, equating to payouts at 50%, 100% and 200%, respectively, and each goal was assigned a weighting relative to the other annual goals. Results between Threshold and Target or between Target and Maximum were based on interpolation. Performance below Threshold would have earned 0%, and performance that exceeded the Maximum would be capped at the Maximum level. The total annual incentive earned by an executive was the sum of the weighted annual incentive amounts earned with respect to each goal.

To further encourage executive retention and align the interests of our executives with our shareholders, more than half of the annual incentive earned was paid in “Performance Equity Grants” comprised of Share Awards and/or Option Awards. These Share Awards cliff vest, in full, on the three-year anniversary of the grant date, and Option Awards vest ratably over three years, all subject to continuous employment and retirement provisions.

The remaining portion of the annual incentive earned was paid in cash (the “Performance Bonus”) and/or, at the executive’s option, in the form of immediately vested restricted units or Option Awards.

Total: |  | 100% |  |  | 100% |

Long-Term Incentive Plan

The third component of the program in 2024 was the Long-Term Incentive Plan (“LTI Plan”), which allows the executive to earn from 0% to 200% of a target number of Share Awards, as determined by the Company’s relative Total Shareholder Return (“TSR”) and achievement of Net Debt to Normalized EBITDAre (defined below) and Normalized Funds From Operations (“Normalized FFO”) per share over a forward-looking three-year performance period compared to pre-established quantitative performance metrics. The LTI Plan aligns the interests of our executives directly with the interests of our shareholders. We refer to such awards subject to settlement under the LTI Plan as “LTI Awards.” LTI Awards cliff vest, in full, following the three-year anniversary of the grant date, after determination of performance by the Compensation Committee and subject to continuous employment and retirement provisions. The LTI Awards were granted to executives in January 2024, at the target dollar amounts

Compensation Discussion and Analysis

shown on page 33, covering the three-year performance period from January 1, 2024 through December 31, 2026, with the following pre-established quantitative performance metrics and potential payout levels:

|  |  | Performance Level (1)
% of Award |  | Metric |  | Threshold |  | Target |  | Maximum
35.0% |  | Performance of Company relative to weighted average TSR of companies in the FTSE Nareit Equity Apartments Index (“Nareit Apartment Index”) (2) |  | (400) bps |  | 0 bps |  | 400 bps
20.0% |  | Performance of Company relative to weighted average TSR of companies in the FTSE Nareit Equity REIT Index (“Nareit Equity Index”) (2) |  | (500) bps |  | 0 bps |  | 500 bps
22.5% |  | Net Debt to Normalized EBITDAre (3) |  | 6.00x |  | 5.00x to 4.00x |  | 3.00x
22.5% |  | Normalized FFO per share (4) |  | $3.80 |  | $3.84-$3.86 |  | $3.93

(1)
Performance results with respect to each metric at Threshold, Target and Maximum equate to payouts of 50%, 100% and 200%, respectively. Results between Threshold and Target or between Target and Maximum are based on interpolation. Performance below Threshold earns 0% and above Maximum is capped at the Maximum level.
(2)
TSR performance relative to the companies that comprise the Nareit Apartment Index and Nareit Equity Index is measured using the weighted index basis points approach, which measures Company performance using the number of basis points above or below the weighted average of the respective index. The Company's TSR represents the compounded annual return of an investment in common shares of the Company over the performance period, with the beginning share price being the average of the last 20 trading days prior to the beginning of the performance period and the ending share price being the average of the last 20 trading days of the performance period. The TSR of each of the companies comprising the Nareit Apartment Index and Nareit Equity Index over the performance period is calculated generally using the same methodology as that used for the calculation of the Company’s TSR.
(3)
Generally, Threshold performance on the Net Debt to Normalized EBITDAre metric will not be less than the highest end of the range set forth in the Company’s most recent leverage policy approved by the Board. “Net Debt” means the Company’s total debt less cash and cash equivalents and mortgage principal reserves/sinking funds as calculated in the Company’s quarterly earnings release. “Normalized EBITDAre” means the Company’s “Normalized Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate” as defined in the Company’s most recent quarterly earnings release at any given time. The achievement of this metric will be determined on a quarterly basis, and the average of the twelve quarters of each computation in the Company’s quarterly earnings releases will be used in the final determination of the LTI Award.
(4)
No later than March 31 of each calendar year in the performance period, the Compensation Committee will establish the Threshold, Target and Maximum performance level metrics for such calendar year. The Threshold, Target and Maximum Normalized FFO per share performance level metrics for 2024 were established by the Compensation Committee in March 2024. The midpoint of the Target range was equal to the midpoint of the Company’s range for Normalized FFO per share expectations for the year, as announced on January 30, 2024 as part of the Company’s public earnings release. See page 37 for more information on Normalized FFO per share and its significance to the Company. The achievement of this metric will be determined on an annual basis and the average of the three years will be used in the final determination of the LTI Award.

The Compensation Committee, as promptly as practicable following the conclusion of the performance period, shall determine the resulting settlement, if any, of LTI Awards compared against the performance metrics established for the period.

Executives participating in the LTI Plan elect prior to the start of the performance period to settle the LTI Award in restricted shares and/or restricted units. With respect to an award that will be settled in the form of restricted shares, the Company does not pay the grantee any dividends on such shares during the performance period. Once the number of restricted shares to be issued, if any, has been determined, the Company will make a cash payment to the grantee in an amount equal to all dividends that would have been paid on those restricted shares had they been outstanding and entitled to dividends during the performance period.

For income tax reasons, grantees of awards that will be settled in the form of restricted units: (i) will be issued restricted units at the time of grant at the maximum amount but such units will be subject to forfeiture (other than the hereinafter described partial distributions paid thereon, which are not subject to forfeiture) at the end of the performance period depending on actual performance and (ii) will be paid a distribution in the amount of 10% of any distributions paid on OP Units during the performance period. Once the final resulting number of restricted

units, if any, has been determined, the Operating Partnership will make a cash payment to the grantee in an amount equal to all distributions that would have been paid on those restricted units had they been outstanding and entitled to distributions during the performance period, less any previously paid partial distributions.

Compensation Risks

The Compensation Committee reviewed the elements of the Company’s compensation to determine whether they encourage excessive risk taking and concluded that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks, and that any risks arising from the Company’s compensation policies are not reasonably likely to have a material adverse effect on the Company.

Pay Mix

The Compensation Committee believes that as the responsibilities of our executives increase, the proportion of their total compensation that is at risk and dependent on performance should also increase. Accordingly, a significant portion of our executives’ total target compensation was outside of base salary and therefore determined on the basis of performance: approximately 91% for Mr. Parrell and an average of 83% for the other NEOs. Furthermore, 50% of Mr. Parrell’s target compensation and an average of 29% of the target compensation

Company Highlights

Acquired ~$1.6B of operating properties (avg. age 5 years) and disposed of ~$975.6M of operating properties (avg. age 35 years) | 1.9% increase in dividend rate year-over-year | 20.7% 2024 total shareholder return | Included in both the Dow Jones Sustainability World and North America Indices, the first residential REIT to receive this distinction

Driven by our corporate purpose of “Creating communities where people thrive,” in 2024 we continued our long track record of creating value through sound capital allocation, focused and proactive revenue generation and expense management while maintaining a conservative balance sheet and taking corporate responsibility into account. In doing so, we:(1)

•
Exceeded the range of our original guidance for growth in year-over-year Same Store Net Operating Income ("NOI") and reached the high end of our original guidance for growth in year-over-year same store revenue, driven by strong demand.
•
Increased our dividend by 1.9% in March 2024, reflecting the strength of the Company's business.
•
Acquired approximately $1.6 billion of operating properties for prices that we believe were generally at a discount to replacement cost and that were on average five years old with a weighted average Acquisition Cap Rate of 5.1% and sold approximately $975.6 million of operating properties that were on average 35 years old at a weighted average Disposition Yield of 5.4%, which we believe improved portfolio quality and long-term returns. These transactions continued to advance our strategy of investing in our Expansion Markets and reducing exposure to older or lower returning assets in selected Established Markets, with approximately 10% of our assets (based on NOI) now located in our Expansion Markets.
•
Issued $600.0 million in 10-year unsecured debt with a 4.65% coupon, at the time the lowest 10-year coupon rate issued by a REIT since 2022, and an all-in effective yield of 4.9%.
•
Substantially completed construction on four projects located in our Expansion Markets of Dallas/Ft. Worth and Denver, totaling approximately $338.0 million of development costs.
•
Reported a modest 2.9% increase in same store expenses for the full year of 2024, which was lower than the range of our original guidance and a smaller increase than in 2023, reflecting the Company’s continued success in managing controllable expenses as well as limited real estate tax growth.
•
Invested approximately $274.0 million in Capital Expenditures to Real Estate for Same Store Properties in 2024, approximately 45% of which was NOI-Enhancing and represented Renovation Expenditures for 3,353 same store apartment units in addition to sustainability and property-level technology spend.
•
Enhanced our balance sheet, liquidity and financial flexibility to support our business objectives and growth through increasing the maximum size of our unsecured commercial paper program from $1.0 billion to $1.5 billion.
•
Reported same store Turnover of 42.5% for the full year of 2024, the lowest in the Company's history, demonstrating the depth of demand from its residents.
•
Were recognized for our commitment to sustainability with our inclusion in both the Dow Jones Sustainability World and North America Indices, the first residential REIT to receive this distinction and one of only four U.S. REITs to be included in both indices.
•
Received Nareit’s Residential Sector Leader in the Light award, which recognizes REITs that demonstrate leadership in implementing sustainable investment and operating practices, good governance and transparency.

Were recognized by Newsweek as one of America’s Most Responsible Companies for the sixth consecutive year, a list of top performing companies in corporate social responsibility matters in the U.S.
•
Were named one of Sustainalytics’ Top-Rated ESG Companies for 2025, recognized as Regional Top Rated for 2025.

These highlights were some of the key drivers of performance against the Annual Incentive Plan metrics, as detailed below.

Annual Incentive Plan – Corporate Goal Results

Corporate Goal #1: Annual Growth in Same Store Net Operating Income
Threshold – 50% 1.00% | Target – 100% 1.50%-2.00% | Maximum – 200% 3.00% | 2024 Results 3.10% | % of Target Achieved 200.00%
Why is this metric important? The Company’s primary financial measure for evaluating the operating performance of its apartment properties is NOI, which 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. Comparing NOI on a “same store” basis (i.e., looking at the exact same set of stabilized apartment properties over the periods being compared) helps investors compare the Company’s operating results to the marketplace. Target: The 2024 Target for Corporate Goal #1 was for the Company to achieve 2024-over-2023 Same Store NOI growth of 1.50%-2.00%. The Target represents a range around the midpoint of the Company’s range for Same Store NOI growth expectations for the year, as announced on January 30, 2024 as part of the Company’s public earnings release. Performance: Actual year-over-year Same Store NOI growth in 2024 was 3.10%, resulting in an achievement of 200.00% of Target. Good demand for our apartments, excellent expense controls even in an inflationary climate, rental rate gains and resident retention were major contributors to the Company’s outperformance on this metric.

Corporate Goal #2: Normalized Funds from Operations per Share
Threshold – 50% $3.80 | Target – 100% $3.84-$3.86 | Maximum – 200% $3.93 | 2024 Results $3.89 | % of Target Achieved 142.86%
Why is this metric important? FFO is widely acknowledged by the REIT industry as being a helpful measure of the operating performance of a real estate company, because it excludes depreciation and gains or losses relating to sales of depreciated real estate. The Company uses “Normalized FFO,” which further excludes other items that by their nature are not comparable from period to period and tend to obscure actual operating results, as a method to compare the operating performance of the Company over a given time period to that of other companies and other time periods in a consistent manner. Target: The 2024 Target for Corporate Goal #2 was for the Company to achieve Normalized FFO of $3.84-$3.86 per share. The midpoint of the Target range was equal to the midpoint of the Company’s range for Normalized FFO per share expectations for the year, as announced on January 30, 2024 as part of the Company’s public earnings release. Performance: Actual Normalized FFO for 2024 was $3.89 per share, resulting in an achievement of 142.86% of Target. The Company’s generation of $3.89 in Normalized FFO per share outperformed the Target primarily as a result of the higher than expected Same Store NOI growth described above.

Corporate Goal #3: Corporate Responsibility
Threshold – 50% | Target – 100% | Maximum – 200% | 2024 Results | % of Target Achieved
10 points | 14 points | 20 points | 17 points | 150.00%
Why is this metric important? Consistent with the Company’s purpose and commitment to the incorporation of corporate responsibility concepts in all aspects of the Company’s business, this goal includes objective performance factors across the corporate responsibility spectrum. Performance Levels: The 2024 Target for Corporate Goal #3 was for the Company to achieve 14 points across seven different objective, predetermined factors. Each factor comprising the categories of (i) sustainability, (ii) inclusion, employee engagement and customer satisfaction (collectively, "engagement") and (iii) accountable leadership was assigned a score of 1 (did not achieve target), 2 (achieved target) or 3 (exceeded target) and were added together to produce an overall score for Corporate Goal #3. The sustainability component consisted of publishing an annual Corporate Responsibility Report pursuant to reporting standards consistent with GRI, the Sustainability Accounting Standards Board and the Task Force on Climate-related Financial Disclosures and earning industry-leading third-party recognition; and outperforming the midpoint of scores received by a select set of peers on the GRESB Real Estate Assessment, the S&P Global Corporate Sustainability Assessment ("CSA") and the Carbon Disclosure Project ("CDP") assessment. The engagement component consisted of achieving a score on survey questions measuring employee perception of the Company’s commitment and accountability with respect to inclusion equal to the median of Qualtrics', our survey vendor's, book of business; achieving a score on employee engagement through an annual third-party anonymous survey of our workforce equal to the median of the property management sector as determined by Workforce Science Associates, a vendor that works with Qualtrics; and achieving an overall customer satisfaction rating of 4.0 on "Welcome Home" and check-up surveys completed by our residents. The accountable leadership component consisted of achieving at least 95% manager compliance on employee Code of Ethics training; and achieving at least 95% manager compliance on employee anti-harassment training. Performance: Actual scoring in 2024 was 17 points overall, resulting in an achievement of 150.00%. The sustainability component received a score of 5 points (1 above target) as a result of being recognized as an industry leader in corporate responsibility and receiving scores on the GRESB Real Estate Assessment, the CSA and the CDP assessment, on average, consistent with the midpoint of our selected peers' scores. Notably, the Company outperformed its peers on the CSA, leading to its inclusion in the Dow Jones Sustainability World and North America Indices. The engagement component received a score of 7 points (1 above target) as a result of our inclusion score of 84.4% placing us above the Qualtrics' book of business median score, our engagement score being equal to the median score of the property management sector as determined by Workforce Science Associates' book of business, and our customer satisfaction rating being slightly above our target. The accountable leadership component received a score of 5 points (1 above target) as a result of a strong compliance push, achieving almost 100% compliance with Code of Ethics training and 95% compliance with anti-harassment training.

Corporate Goal #4: Normalized G&A and Property Management Costs
Threshold – 50% $187.5M | Target – 100% $184.0M-$185.0M | Maximum – 200% $179.5M | 2024 Results $189.4M | % of Target Achieved 0.00%
Why is this metric important? The Company believes that looking at general and administrative (“G&A”) and property management costs enables investors to analyze the efficiency of the Company’s stewardship of its capital. This metric, which the Company normalizes to exclude certain non-comparable or duplicative charges (such as costs relating to accounting rule changes), includes the personnel and other overhead costs incurred by the Company to generally manage its operations, investments, finance and legal activities. The Company monitors this metric carefully as it is a measure of efficiency in managing its business. Target: The ultimate 2024 Target for Corporate Goal #4 was for the Company to limit its normalized G&A and property management costs to between $184.0 and $185.0 million. Performance: Actual G&A and property management costs totaled $189.4 million, resulting in an achievement of 0.00% of Target. The Company's incurrence of $189.4 million in G&A and property management costs underperformed primarily as a result of increased legal expenses related to unanticipated litigation. Excluding the unanticipated litigation expenses, G&A and property management costs generally grew in line with management's expectations.

Annual Incentive Plan – Performance of the Chief Executive Officer

To determine the amounts of Mr. Parrell’s 2024 Performance Bonus and Performance Equity Grant, the Compensation Committee calculated results on the Corporate Goals, as delineated above, and assigned a score to his Individual Goals. The independent trustees of the Board then approved such calculations, scores and overall compensation.

Mr. Parrell’s Individual Goals for 2024, which were assigned by the Compensation Committee, included capital allocation, innovation and technology initiatives, investor perception and understanding, advancement of the Company's corporate responsibility strategy and initiatives, succession planning across the organization, as well as impacting political and regulatory matters important to the Company.

In reviewing Mr. Parrell’s performance on his Individual Goals, the Compensation Committee noted the following accomplishments:

•
Steering the Company's capital allocation strategy of investing in our Expansion Markets, with approximately 10% of our assets (based on NOI) now located in our Expansion Markets, and reducing exposure to older or lower returning assets in selected Established Markets, resulting in acquisitions of approximately $1.6 billion of operating properties for prices that we believe were generally at a discount to replacement cost and that were on average five years old with a weighted average Acquisition Cap Rate of 5.1% and dispositions of approximately $975.6 million of operating properties that were on average 35 years old at a weighted average Disposition Yield of 5.4%, which the Company believes improved portfolio quality and long-term returns. Together with the funding of $600.0 million in fixed rate long-term debt at an attractive rate, these transactions resulted in minimal current period dilution;
•
Also as part of the Company's capital allocation strategy, (i) efficiently executing the Company's spend on Capital Expenditures to Real Estate, approximately 45% of which was NOI-Enhancing; and (ii) executing additional share buybacks at an attractive price point and while maintaining the Company's liquidity, scale and balance sheet strength;

A comparison of this result to prior years illustrates the true variability of the Company’s Executive Compensation Program. The total percentage of target achieved for the 2018-2020, 2019-2021, 2020-2022(1) and 2021-2023 LTI Plans were 61.23%, 85.74%, 25.83% and 95.56%, respectively.

(1)
No changes were made to the 2020-2022 LTI Plan notwithstanding that the performance metrics were set approximately 60 days prior to the start of the COVID-19 pandemic.

The Company's TSR performance relative to the Nareit Apartment Index and the Nareit Equity Index collectively represent 55% of the outcome of the 2022-2024 LTI Plan. The above chart does not include Net Debt to Normalized EBITDAre and Normalized FFO per share, which collectively represent 45% of the 2022-2024 LTI Plan. These are measures the executives directly impact and which the Board believes are important to shareholder performance.

(1)
Annual salary equates to 100.00% achievement.
(2)
As a comparison, Mr. Parrell’s equivalent total achieved compensation as a percentage of target achieved for 2021, 2020 and 2019 was 125.38%, 55.96% and 121.61%, respectively.
(3)
As a comparison, Mr. Garechana’s equivalent total achieved compensation as a percentage of target achieved for 2021, 2020 and 2019 was 120.27%, 69.18% and 113.95%, respectively.
(4)
As a comparison, Mr. Manelis’ equivalent total achieved compensation as a percentage of target achieved for 2021, 2020 and 2019 was 120.98%, 72.56% and 117.71%, respectively.
(5)
As a comparison, Mr. Brackenridge's equivalent total achieved compensation as a percentage of target achieved for 2021 and 2020 was 125.66% and 68.85%, respectively. Mr. Brackenridge was not a participant in the 2019 LTI Plan. Thus, there are limited historical percentages of target achieved for comparison purposes.
(6)
As a comparison, Mr. Fenster’s equivalent total achieved compensation as a percentage of target achieved for 2021, 2020 and 2019 was 120.50%, 75.51% and 115.14%, respectively.

Compensation Discussion and Analysis

## Benchma rking

To measure the Company’s executive compensation for competitiveness in the industry, the Compensation Committee engaged Ferguson Partners Consulting (“Ferguson Partners”), a nationally recognized independent compensation consultant, to conduct an analysis that benchmarked the Company’s executive compensation against a peer group of other large REITs (by capitalization).

The Compensation Committee believes that the use of peer market data is important in developing a competitive compensation program. The Compensation Committee and Ferguson Partners consider qualitative factors (such as tenure and experience in the role), internal equity and external market data in making both individual and plan-level compensation decisions. While the Compensation Committee does not target a specific percentile range within the peer group, this benchmarking data provides a reference point in determining if pay components and program designs are reasonable when ultimately making compensation decisions.

The Compensation Committee reviews the peer group annually to ensure the included companies still serve as appropriate comparisons to the Company. Target compensation and incentive opportunity levels are continuously evaluated and are adjusted when appropriate, to ensure market comparability.

Ferguson Partners performed its annual executive compensation study in 2024, which showed that the total target compensation of our Chief Executive Officer and the remaining executive team generally aligns with the market median of the peer group data.

The Compensation Committee conducted a conflict of interest assessment for 2024 services and concluded that no conflict of interest existed with respect to the work of Ferguson Partners.

## Compensation C lawback Policy

In 2023, the Board amended the Company's incentive-based executive compensation clawback policy to conform with newly issued SEC rules and NYSE listing standards regarding executive recoupment policies. If the Company is required to restate its financial results due to material noncompliance with any financial reporting requirement under the U.S. securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, the result of which is that any incentive-based compensation received by an executive during the three completed fiscal years immediately preceding the date on which the Company was required to prepare a restatement (the “Awarded Compensation”) would have been lower (the “Actual Compensation”) had it been calculated based on such restated results, the Compensation Committee must seek to recover for the benefit of the Company all of the difference between the Awarded Compensation and the Actual Compensation, computed without regard to any taxes paid. The policy is available on the Company’s website at www.equityapartments.com in the Investor section under “Corporate Governance.” The policy is not part of or incorporated into this Proxy Statement.

## Policies and Practices Related to the Timing of Certain Equity Awards

Each January, the Compensation Committee, and subsequently the Board, reviews and approves the aggregate dollar value of the equity compensation to be awarded (inclusive of Share Awards and Option Awards) to executives under the Annual Incentive Plan. The grant of approved equity awards then occurs two business days after the Company has made public its fourth-quarter earnings release on Form 8-K. Share Awards and Option Awards under our Annual Incentive Plan are granted to our executives at the same time as Share Awards and Option Awards are granted to our other employees. Each June, the Compensation Committee, and subsequently the Board, reviews and approves the aggregate dollar value of the equity compensation to be awarded (inclusive of Share Awards and Option Awards) to our trustees, which is granted on the date of the annual meeting of shareholders for service through the next annual meeting of shareholders. The number of awards granted is calculated based on (i) the closing price of the common shares on the NYSE on the grant date (or a discount thereto in the case of restricted units) for Share Awards and (ii) the Black-Scholes option value as of the grant date for Option Awards.

We may grant equity awards, including Option Awards, to eligible employees outside of our annual award cycle for new hires, promotions, recognition, retention, or other purposes. In determining when to grant “off-cycle” Option Awards, the Compensation Committee generally would seek to do so at a time when the Company is not expected to be in possession of material non-public information regarding our business.

During 2024, the Company did not (i) time the disclosure of material non-public information for the purpose of affecting the value of executive compensation, or (ii) grant any Option Awards to any of its NEOs in any period beginning four business days prior to the filing of a periodic report on Form 10-Q, Form 10-K or current report on Form 8-K that discloses material non-public information, and ending one business day after the filing of such Form 10-Q, Form 10-K or Form 8-K.

Share Awards and Option Awards. The dollar amount shown is the grant date fair value of the Share Awards and Option Awards granted under the Company’s Annual Incentive Plan during the listed years for services performed in the prior year and the target grant date fair value of the LTI Awards granted under the LTI Plan during the listed years and which are settled at the end of the applicable three-year performance period. As further described in the CD&A, the actual amounts paid out at the end of the respective three-year performance periods may range from 0% to 200% of the target number of LTI Awards. The settlement of the awards under the 2022 LTI Plan is described on pages 43-46 in the CD&A. The grant date fair value of the 2024 LTI Awards, if earned at the 200% maximum level, for each of the NEOs is: $10,349,950 for Mr. Parrell; $2,219,884 for Mr. Garechana; $2,639,918 for Mr. Manelis; $2,219,962 for Mr. Brackenridge; and $1,102,420 for Mr. Fenster. Assumptions used in the calculation of grant date fair value for the primary grant of Share Awards and Option Awards for 2024, 2023 and 2022 are included in footnote 11 of the audited financial statements included in the Company’s Annual Report on Form 10-K for 2024.

(1)
Represents the 2024 grant of Share Awards and Option Awards for services performed in 2023 which were approved by the Board on January 22, 2024. The Share Awards vest in full on the third anniversary of the grant date, subject to continuous employment and retirement provisions. The Option Awards were granted at an exercise price of $60.96, the closing price of the common shares on the grant date, and vest in approximately equal installments over three years, subject to continuous employment and retirement provisions.
(2)
Represents the threshold (50%), target (100%) and maximum (200%) number of LTI Awards approved by the Board on December 14, 2023 and granted in January 2024 for the 2024-2026 performance period. The target number of LTI Awards is derived by dividing the grant date fair value of such awards by the Monte Carlo value as of the date of the award of $59.70 per restricted unit and $62.64 per restricted share. For additional information regarding the terms of LTI Awards, including vesting schedule and dividends, see the CD&A.
(3)
The grant date fair value of the Share Awards was calculated based on a price of (i) $57.55 per restricted unit, a 5.6% reduction to the closing price of the Company’s common shares on the grant date to take into account various risks associated with restricted units, such as book-up risk, and (ii) $60.96 per restricted share, the closing price of the common shares on the grant date. The grant date fair value of the Option Awards was calculated using a Black-Scholes option value as of the date of the award of $11.01 per option. The grant date fair value of the LTI Awards reflects the value of the number of LTI Awards if earned at Target, using a Monte Carlo value as of the date of the award of $59.70 per restricted unit and $62.64 per restricted share. See footnote 11 of the audited financial statements included in the Company’s Annual Report on Form 10-K for 2024 for additional discussion of the assumptions used in calculating grant date fair value of the LTI Awards and the Option Awards.

## Pension Benefits

The Company does not have a pension plan for its executives and therefore, there are no pension benefits to disclose.

## Nonqualified Defe rred Compensation

The following table shows the current value of the compensation previously earned and deferred by the NEOs to the Company’s employee-funded SERP during 2024. As the Company does not make contributions to the SERP and does not guarantee any investment return, the balances shown are comprised entirely of contributions made by the NEOs from their salary, Performance Bonus or Performance Equity Grants for prior years and the earnings on those amounts.

All amounts contributed by a NEO in prior years have been reported in the Summary Compensation Tables in our previously filed proxy statements in the year earned to the extent he was a NEO in such year for purposes of the SEC’s executive compensation disclosure rules.

The SERP allows all Company employees with annual total cash compensation of $155,000 or more to defer receipt of up to 25% of their base salary and up to 100% of their cash Performance Bonus and incentive compensation. Any of this deferred cash compensation is deposited by the Company directly with the independent trustee of the SERP and invested, at the option of the participant, in a limited number of independent mutual funds. The SERP also allows the same eligible employees to defer receipt of restricted shares. Deferral

elections are generally made by eligible employees during an open enrollment period each year for amounts to be earned or granted in the following year. Benefits under the SERP will be paid out, in either a lump sum or in annual installments, upon certain events such as termination of employment, disability, death, change in control or, in some cases, a one-time distribution at or after age 50.

## Potential Payments Upon Termination of Employment or Change in Control

Change in Control Agreements

The Company has Change in Control Agreements (the “CIC Agreements”) with Messrs. Parrell, Garechana, Manelis, Brackenridge and Fenster that entitle them to receive certain severance payments upon termination of employment following a Change in Control. As a condition to receiving the payments and benefits under the CIC Agreement, each NEO must execute a general release of claims in favor of the Company.

The Company adopted the CIC Agreements to help ensure that the Company’s executives maintain neutrality in their decision-making process and act in the best interests of shareholders in the event of a potential merger or acquisition. A “Change in Control” will generally be deemed to have occurred upon a third party’s acquisition of 30% or more of the Company’s common shares or assets, whether through purchase, merger or consolidation.

In the event that Mr. Parrell is dismissed without Cause or resigns for Good Reason (each as defined in the CIC Agreements) during the three-year period following a Change in Control, he will be entitled to all accrued but unpaid compensation, a prorated bonus and an incentive compensation grant through the date of termination and a lump sum cash severance payment equal to a 2.25 multiple of his annual base salary plus the average of his annual Performance Bonus for the last three calendar years. In the event that Messrs. Garechana, Manelis, Brackenridge or Fenster is dismissed without Cause or resigns for Good Reason during the two-year period following a Change in Control, such NEO will be entitled to all accrued but unpaid compensation, a prorated bonus and long-term incentive compensation grant through the date of termination and a lump sum cash severance payment equal to a 2.25 multiple of the NEO's annual base salary plus the NEO's target annual Performance Bonus and target Performance Equity Grant. Each NEO is also entitled to continued medical, dental, life and disability benefits for 2.25 years.

Pursuant to the Company’s 2019 Share Incentive Plan (the “Share Incentive Plan”), an employee, including NEOs, will receive accelerated vesting of unvested Option Awards and Share Awards upon the termination of such employee (other than for Good Cause (as defined in the Share Incentive Plan)) at or within 24 months following a Change in Control. In the event a Change in Control occurs prior to the end of the performance period under any incomplete LTI Plan, each such LTI Award will be valued as though the performance period had ended on the date of the Change in Control to determine the actual number of restricted shares issued and/or restricted units retained by each NEO, with accelerated vesting to occur only upon a termination as described in the previous sentence or as a result of death or disability as described below.

If any payments made to Mr. Parrell would result in an excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (“IRC”), he would become entitled to receive a tax reimbursement that would put him in the same financial position after-tax that he would have been in if the excise tax did not apply to such amounts. The Company will not enter into any new agreements with its executives that include excise tax gross-up provisions with respect to payments contingent upon a Change in Control, and has not since March 2009.

If any payments or benefits received or to be received by Messrs. Garechana, Manelis, Brackenridge or Fenster would subject the NEO to the excise tax imposed by the IRC, the NEO’s payments and benefits will be reduced to the extent necessary to avoid such excise tax, but only if such a reduction of pay or benefits would result in a greater net after-tax amount for the NEO. If not, the NEO’s payments and benefits would be subject to excise tax. This provision is commonly referred to as a “modified cutback.”

Executive Compensation

Executive Severance Plan

The Company has an Executive Severance Plan (the "Severance Plan") applicable to Messrs. Parrell, Garechana, Manelis, Brackenridge and Fenster that entitles them to receive certain severance payments in the event of a termination of employment by the Company without Cause (and other than as a result of the NEO's death or disability) or by the NEO for Good Reason (each as defined in the Severance Plan and each event, a “Qualifying Termination”).

The Company adopted the Severance Plan to provide a standardized and typical framework for severance arrangements that will provide increased certainty for the Company's executives and the Company in the event of a non-change in control severance. The Severance Plan is expected to assist the Company with the retention and recruitment of key executives, provide the Company with important protections and reduce costs in the event of a dispute.

As a condition to becoming eligible for benefits under the Severance Plan, a NEO must enter into a participation notice and agreement. Receipt of benefits under the Severance Plan is also subject to the NEO's execution and non-revocation of a general release of claims in favor of the Company and continued compliance with the restrictive covenants related to post-employment non-solicitation and non-competition for 24 months for the Chief Executive Officer or 18 months for the other NEOs following a Qualifying Termination and indefinite covenants covering trade secrets, confidentiality and non-disparagement.

In the event of a Qualifying Termination with respect to Mr. Parrell, he will be entitled to all accrued but unpaid compensation; a lump sum prorated cash payment based on his target annual Performance Bonus and target Performance Equity Grant; and a cash severance payment equal to a 2.0 multiple of his annual base salary plus his target annual Performance Bonus, payable in equal monthly installments over 24 months.

In the event of a Qualifying Termination with respect to Messrs. Garechana, Manelis, Brackenridge or Fenster, such NEO will be entitled to all accrued but unpaid compensation; a lump sum prorated cash payment based on his target annual Performance Bonus and target Performance Equity Grant; and a cash severance payment equal to a 1.5 multiple of his annual base salary plus his target annual Performance Bonus, payable in equal monthly installments over 18 months.

The Company and the applicable NEO will share responsibility for the payment of premiums required to maintain medical, dental and vision COBRA continuation coverage for such NEO and his dependents and beneficiaries under the Company's group health insurance plan at substantially the same level as provided immediately prior to a Qualifying Termination, with such NEO paying the same portion of the premium which he had been paying (or such amount as similarly situated active Company executives would pay) and the Company covering the remaining cost, for a period of 24 months for Mr. Parrell or 18 months for the other NEOs.

Each NEO is also entitled to a cash payment equal to the sum of each LTI Award that is incomplete as of the date of Qualifying Termination, with each LTI Award pro rated based on the number of days elapsed under each LTI Plan in relation to the full 36 months in the performance period, valued as if the performance period ended on the date of Qualifying Termination, vested, and paid in equal monthly installments over 24 months for Mr. Parrell or 18 months for the other NEOs. Any unvested Option Awards and Share Awards held by a NEO will immediately vest at the time of a Qualifying Termination, and any vested Option Awards will continue to be exercisable until the expiration of the severance payment period, which is 24 months for Mr. Parrell and 18 months for the other NEOs.

Death, Disability and Retirement Benefits

While the Company has no mandatory retirement age for employees, the Company’s Share Incentive Plans do provide for certain benefits for employees upon voluntary retirement at or after age 62 or upon meeting certain age/length of service requirements. For employees hired prior to January 1, 2009 and who were at least 59 years old as of February 1, 2019 (“age 62 eligible employees”), retirement will mean the voluntary termination of employment (other than for Good Cause (as defined in the Share Incentive Plan)): (i) at or after age 62; or (ii) prior to age 62 after meeting the requirements of the Rule of 70 (defined below). For all other employees, retirement will mean the voluntary termination of employment (other than for Good Cause) after meeting the requirements of the Rule of 70.

The “Rule of 70” is met when an employee’s years of service with the Company (which must be at least 15 years) plus his or her age (which must be at least 55 years) on the date of retirement equals or exceeds 70. In addition, the employee must give the Company at least six months’ advance written notice of his or her intention to retire and sign a release upon termination of employment, releasing the Company from customary claims and agreeing to ongoing non-competition and employee non-solicitation provisions. The Rule of 70 does not apply to trustees.

For age 62 eligible employees who retire at or after age 62 or for trustees who retire at or after age 72, such individual’s unvested Share Awards and Option Awards would immediately vest, and Option Awards would continue to be exercisable for the balance of the applicable 10-year option period. For all other employees (and those age 62 eligible employees who choose to retire prior to age 62), upon retirement under the Rule of 70, such employee’s unvested Share Awards and Option Awards would continue to vest per the original vesting schedule (subject to immediate vesting upon the employee’s death or disability), and Option Awards would continue to be exercisable for the balance of the applicable 10-year option period, subject to the employee’s compliance with the non-competition and employee non-solicitation provisions. If an employee violates these provisions after such retirement, all unvested Share Awards and unvested and vested Option Awards at the time of the violation would be void, unless otherwise approved by the Compensation Committee.

Pursuant to each LTI Plan, if death, disability or a qualifying retirement (either age 62 or the Rule of 70) with respect to a NEO occurs during the first year of the performance period, such NEO's LTI Award will be prorated in the proportion that the number of days employed during such year bears to 365 (or 366 if such year is a leap year). The number of resulting restricted shares and/or restricted units (based on the pro-rated LTI Award) would continue to be determined at the end of the performance period. Vesting is immediate for death, disability and age 62 retirement events, provided the grantee signs a release in a form that is reasonably satisfactory to the Company releasing the Company from customary claims in the case of age 62 retirement. In the event of a Rule of 70 retirement, vesting continues after retirement per the original schedule, provided the grantee signs a release in a form that is reasonably satisfactory to the Company releasing the Company from customary claims and also containing non-competition and employee non-solicitation provisions and complies with such non-competition and employee non-solicitation provisions. None of the NEOs are "age 62 eligible employees" and thus would not receive accelerated vesting under the LTI Plans in the case of retirement.

Pursuant to the Company's Share Incentive Plan, an employee will receive accelerated vesting of unvested Option Awards and Share Awards upon the death or disability of such employee.

Executive Compensation

## CEO Pay Ratio

SEC rules require us to set forth the ratio that annual total compensation for Mr. Parrell bears to the median annual total compensation of the Company’s employees, other than Mr. Parrell. The Company has approximately 2,500 employees located solely within the United States, with approximately 650 located in the Company’s Chicago headquarters and other corporate offices, and the remaining approximately 1,850 serving our residents every day on-site at our communities.

For purposes of calculating annual total compensation under SEC rules, the Company identified a median employee as of December 31, 2023. The median employee was identified by using the same calculation methodology for 2023 total compensation as used for the Chief Executive Officer’s “Total Compensation” as reflected in the Summary Compensation Table, but removing from the calculation any Company matching contributions to the 401(k) plan, as employee participation in such plan varies. This method was consistently applied to all employees other than the Chief Executive Officer, whose compensation is excluded for purposes of identifying the median employee. The Company used its actual employee population as opposed to a statistical sampling or other method.

SEC rules permit us to use the same median employee for up to three years unless there has been a change in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change in our pay ratio disclosure. In the event of such a change, SEC rules permit us to use another employee whose compensation is substantially similar to the original median employee based on the compensation measure used to select the original median employee. The median employee we selected on December 31, 2023 is no longer with the Company. Accordingly, the Company revisited the data from December 31, 2023 and selected a substitute median employee as of December 31, 2024 whose compensation was next closest to the original median employee’s compensation value and calculated 2024 total compensation for such employee using the same methodology as used for Mr. Parrell's Total Compensation as reflected in the Summary Compensation Table. Based on this calculation, the 2024 total compensation for our median employee was $71,418 and the 2024 total compensation for Mr. Parrell as reflected in the Summary Compensation Table was $11,359,954. The ratio of Mr. Parrell’s compensation to that of the median employee is 159:1. Because the SEC rules for identifying the median employee and calculating the pay ratio permit companies to use various methodologies and assumptions, and to apply certain exclusions and to make reasonable estimates that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio that we have reported.

As an owner and self-operator of over 300 apartment properties, the Company employs significantly more on-site property-level employees than real estate companies in other sectors, such as office and retail, or those that hire outside property management companies. Rather than outsourcing property management, the Company’s strategy generally includes self-management of its assets, which aligns the long-term investment interests of our shareholders with our focused management of income, expense and capital expenditures. This alignment of interest allows our employees to act as owners, a strategy that has served our shareholders well in the long-term.

Over the last ten years, shareholders have approved our Executive Compensation Program by an average of 93% support of the votes cast. As set forth in the CD&A, we believe our shareholders’ overwhelming support for the Company’s compensation program reflects the strong alignment between our Chief Executive Officer’s pay and performance.

Relationship of CAP to Company Performance

The following graphs illustrate the relationship between the CAP to our PEO and the average CAP to our non-PEO NEOs, and (i) our cumulative Company TSR and cumulative Peer Group TSR, (ii) our GAAP net income and (iii) our Normalized FFO per share, in each case for the fiscal years ended December 31, 2020, 2021, 2022, 2023 and 2024.

CAP vs. Company TSR and Peer Group TSR

Chart

CAP is determined to a large extent by reference to our share price on the particular day of the valuation of Share Awards and Option Awards per SEC rules. Company TSR and Peer Group TSR illustrated in the graph above are calculated using the measurement period beginning on the last trading day of 2019, through and including the end of the fiscal year for which cumulative Company TSR or cumulative Peer Group TSR is being calculated.

Equity Residential | 63 | 2025 Proxy Statement

Executive Compensation

Net income is impacted by depreciation and gains or losses from sales of real estate, among other items. While dispositions of real estate are part of the Company's overall strategy, the Company believes the operating performance of its real estate from period to period is a more appropriate measure of its value creation. Accordingly, the Company does not consider net income as an appropriate indicator of the Company's performance and thus does not use the measure in determining executive compensation.

The Company believes Normalized FFO per share is an important measure of the Company's performance and thus has included it as a performance metric in determining executive compensation under both its Annual Incentive Plan and LTI Plan. See page 37 for more information on Normalized FFO per share and its significance to the Company. Under the Company's LTI Plan, the results of Normalized FFO per share are determined for each calendar year of the three-year performance period and the average of the three years is used in the final determination of the LTI Award. Thus, a portion of the CAP to the PEO and non-PEO NEOs reflected in the graph above is based on the results of Normalized FFO per share over a three-year period, in addition to the portion based on the Normalized FFO per share reported for each respective calendar year.

Even though Normalized FFO per share is an important measure for the Company, it may not always show a direct relationship to CAP for at least the following reasons, in addition to the timing considerations discussed in the previous paragraph:

•
This measure is only one component of executive compensation and works in conjunction with the other performance measures comprising the Annual Incentive Plan and LTI Plan (most of which appear in the tabular list below).
•
A portion of the amount of the Share Awards and Option Awards granted to the NEOs depends on the difference between the target amount or range of Normalized FFO per share set by the Compensation Committee for the year and actual results for the year. For example:
o
In 2020, target Normalized FFO per share was determined prior to the COVID-19 pandemic and was not changed, resulting in 0% of target being achieved.
o
In 2021, Normalized FFO per share far exceeded the Company's initial expectations because the Company's business did not decline as much as anticipated at the beginning of 2021 when the Company's public guidance (and executive compensation targets) were determined. This was due to

Equity Residential | 64 | 2025 Proxy Statement

Table of Contents

Executive Compensation

management's aggressive efforts to stabilize the business and unexpectedly rapid improvement in some of our business metrics, resulting in 200% of target being achieved.
•
CAP is determined to a large extent by reference to our share price on the particular day of the valuation of Share Awards and Option Awards per SEC rules, as can be seen by the Company TSR reflected in the PVP Table.

In addition, Normalized FFO per share is a measure based on historical performance, whereas TSR measures are based on share prices, which are forward-looking. Our NEOs' compensation includes both types of measures of value creation, which do not always move in sync, especially over a calendar year period.

The below list sets forth the most important financial performance measures used by the Company to link compensation paid to the NEOs in 2024. For additional information regarding the impact these measures have on executive compensation, please see the CD&A.

Effective in June 2024, the compensation of the Company’s trustees (excluding Mr. Parrell) consists of an annual cash retainer and Share Awards and Option Awards with values as follows, calculated for the fiscal year from the 2024 Annual Meeting of Shareholders to the 2025 Annual Meeting of Shareholders:

|  | Fees
Annual Retainer |  |  |  |
Cash |  |  | $90,000 |

Executive – Member |  |  | 4,000 |

The Board generally reviews its compensation every two years and last provided for an increase in June 2024. The Chairman of the Board fee was instituted in June 2023 following the appointment of our current Chairman, Mr. Neithercut, in May 2023 (his predecessor received an LTI Award for his service in lieu of other trustee fees), and did not increase for 2024.

Trustees who are first appointed or elected to the Board after an annual meeting of shareholders receive prorated cash fees and long-term incentive grants for their service until the next annual meeting of shareholders. The Company also reimburses the trustees for travel and other expenses incurred in connection with their activities on behalf of the Company. Trustees do not have pension benefits and are not entitled to any above-market or preferential earnings on nonqualified deferred compensation. Trustees are eligible to purchase shares not to exceed $100,000 per year under the Company’s Employee Share Purchase Plan at the discounted purchase price under such plan. Non-employee trustees do not participate in the Company’s 401(k) plan and do not receive any matching contributions on any trustee compensation.

For service provided by the Board from the June 2024 Annual Meeting of Shareholders to the June 2025 Annual Meeting of Shareholders, each trustee (with the exception of Mr. Parrell) received an annual long-term compensation grant of $210,000 on June 20, 2024, which was allocated at the election of the trustee to any combination of Share Awards and Option Awards, utilizing the same valuation criteria as approved by the Board for the annual long-term compensation grants to the Company’s executives. All such Share Awards and Option Awards will vest in full on the first anniversary of the grant date. Trustees are also entitled to certain vesting benefits upon retirement, as described in the “Death, Disability and Retirement Benefits” discussion in “Executive Compensation.” Generally, retirement means termination of service on the Board (other than for good cause) on or after age 72.

The dollar value of the restricted shares was calculated based on the closing price of the Company’s common shares on the grant date of $67.85. The dollar value of the restricted units was calculated based on a price of $62.76 per restricted unit, a 7.5% reduction to the closing price of the Company’s common shares on the grant date to take into account various risks associated with restricted units, such as book-up risk. The Option Awards were granted at an exercise price equal to the closing share price of the common shares on the grant date of $67.85. The grant date fair value of $12.32 per Option Award was calculated using the modified Black-Scholes option pricing model and the following assumptions: an estimated time until exercise of 5 years, a volatility of 23.70%, a risk-free interest rate of 4.26% and a dividend yield of 3.77%.

Each of Ms. Hoff and Ms. Jones was appointed to the Board on March 19, 2024 and received a long-term compensation grant on March 19, 2024, prorated from the date of her appointment to the Board to the 2024 Annual Meeting of Shareholders, in the amount of $48,798, which was comprised of Share Awards that vest in full on the first anniversary of the grant date. The dollar value of the restricted shares was calculated based on the closing price of the Company’s common shares on the grant date of $62.22. The dollar value of the restricted units was calculated based on a price of $57.55 per restricted unit, a 7.5% reduction to the closing price of the Company’s common shares on the grant date to take into account various risks associated with restricted units, such as book-up risk.
(3)
For service as Chairman of the Board from the June 2024 Annual Meeting of Shareholders to the June 2025 Annual Meeting of Shareholders, Mr. Neithercut received a fee of $250,000, which he elected to receive as an Option Award, the terms and value of which were determined in the same manner as Option Awards granted to other trustees as described in footnote (1) to this table.

The Company entered into an Executive Retirement Benefits Agreement with Mr. Neithercut in February 2001 which provides him, after his retirement from the Company, with health and life insurance benefits for the remainder of his life in the same amounts and at the same rates as applicable to any then employed executive. Based on current assumptions, the present value of these payments as of December 31, 2024 is $503,590.

# Audit Committ ee Report |

The Audit Committee reviews the Company’s financial reporting process on behalf of the Board. The Company’s management has the primary responsibility for establishing and maintaining adequate internal financial controls, for preparing the financial statements and for the public reporting process. Ernst & Young LLP (“Ernst & Young”), the Company’s independent registered public accounting firm for 2024, was responsible for expressing opinions on the conformity of the Company’s audited financial statements with generally accepted accounting principles and on the effectiveness of the Company’s internal controls over financial reporting.

In this context, the Audit Committee has reviewed and discussed with management and Ernst & Young the audited financial statements for the year ended December 31, 2024, and Ernst & Young’s evaluation of the Company’s internal controls over financial reporting. The Audit Committee has discussed with Ernst & Young the matters that are required to be discussed by applicable auditing standards. Ernst & Young has provided to the Audit Committee the written disclosures and the letter required by applicable independence standards, and the Audit Committee has discussed with Ernst & Young the firm’s independence. The Audit Committee has concluded that Ernst & Young’s provision of audit and non-audit services to the Company and its affiliates is compatible with Ernst & Young’s independence.

In reliance on the review and discussions referred to above, the Audit Committee recommended to the Board the inclusion of the Company’s audited consolidated financial statements in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, for filing with the SEC.

Introduction

At the Annual Meeting, shareholders will be asked to elect ten trustees to serve until the 2026 Annual Meeting and until their respective successors are duly elected and qualified. Following the recommendation of the Corporate Governance Committee, the Board has nominated all of the Company’s current trustees: Angela M. Aman, Linda Walker Bynoe, Mary Kay Haben, Ann C. Hoff, Tahsinul Zia Huque, Nina P. Jones, David J. Neithercut, Mark J. Parrell, Mark S. Shapiro and Stephen E. Sterrett for election, with the exception of John E. Neal who will not be standing for re-election as a result of his retirement from the Board. Biographies of each of our nominated trustees, which include a brief discussion of the specific experience, qualifications, attributes and skills that led to the Board’s conclusion that such individual should serve as a trustee of the Company, are set forth above in “Governance of the Company – Biographical Information and Qualifications of Trustees.” The process undertaken by the Corporate Governance Committee in recommending qualified trustee candidates is described above under “Governance of the Company – Board Composition and Trustee Nomination Procedures.”

Independence of Trustees

Pursuant to the Company’s Corporate Governance Guidelines, which require that a majority of our trustees be independent within the meaning of the NYSE listing standards, the Board undertook a review of the independence of trustees nominated for election at the upcoming Annual Meeting. The Board reviews the relationships and transactions, if any, during the past year between each trustee or any member of his or her immediate family and the Company as necessary to comply with the definition of independence established by the NYSE. During the period covered by this Proxy Statement, for each trustee identified as independent below, there were no transactions, relationships or arrangements not disclosed pursuant to Item 404(a) of Regulation S-K of the type that would need to be considered in connection with determining the independence of such trustees under the applicable NYSE definition of independence.

As a result of this review, the Board affirmatively determined that all the trustees nominated for election at the Annual Meeting are independent of the Company and its management within the meaning of the NYSE listing standards, with the exception of its Chairman (and former Chief Executive Officer and President of the Company), Mr. Neithercut and its Chief Executive Officer and President, Mr. Parrell. The Board previously determined that Mr. Neal, who is retiring from the Board at the Annual Meeting, was independent of the Company and its management within the meaning of the NYSE listing standards.

General Information about the Trustees and Nominees

Our Declaration of Trust currently provides for the annual election of all trustees. All of the nominees are presently trustees, and each has consented to be named in this Proxy Statement and to serve if elected.

Vote Required

A majority of the votes cast in person or by proxy at the meeting at which a quorum is present is required for the election of trustees in an uncontested election. A majority of the votes cast means that the number of votes affirmatively cast “for” a trustee’s election exceeds the number of votes affirmatively cast "against" that trustee's election (with "abstentions" and broker non-votes not counted as a vote cast either "for" or "against" that trustee's election).

Matters for Shareholder Voting

Although we know of no reason why any nominee would not be able to serve, if any nominee should become unavailable for election, the persons named as proxies will vote your shares to approve the election of any substitute nominee proposed by the Board. If any incumbent trustee does not receive a majority of the votes cast for his or her election, the trustee is required to tender his or her resignation for the consideration of the Board. See “Governance of the Company – Board of Trustees – Trustee Resignation Policies” above.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” EACH OF THE ten TRUSTEE NOMINEES.

## Proposal 2 – Ratification of Se lection of the Company’s Independent Registered Public Accounting Firm

The Audit Committee has selected Ernst & Young as the independent registered public accounting firm to perform the audit of our financial statements and our internal controls over financial reporting for 2025. Ernst & Young has served as the Company’s independent registered public accounting firm since 1996, and the Board recommends that the shareholders ratify the Company’s selection of Ernst & Young as our independent registered public accounting firm. Representatives of Ernst & Young will be at the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Annual Evaluation and Selection of Our Independent Registered Public Accounting Firm

The Audit Committee annually evaluates the performance of the Company’s independent registered public accounting firm, including the senior audit engagement team, and determines whether to reengage the current independent registered public accounting firm or consider other public accounting firms. Factors considered by the Audit Committee in deciding whether to retain Ernst & Young include:

•
Ernst & Young’s deep technical expertise and significant institutional knowledge of the Company’s operations and industry;
•
The quality and candor of Ernst & Young’s communications with the Audit Committee and management;
•
Ernst & Young’s independence;
•
The quality and efficiency of the services provided by Ernst & Young, including input from management on Ernst & Young’s performance and how effectively Ernst & Young demonstrated its independent judgment, objectivity and professional skepticism;
•
External data on audit quality and performance, including recent Public Company Accounting Oversight Board (“PCAOB”) reports on Ernst & Young and its peer firms; and
•
The appropriateness of Ernst & Young’s fees, including the overall relationship between fees for audit and non-audit services, Ernst & Young’s tenure as the Company’s independent registered public accounting firm, including the benefits of a longer tenure, and the controls and processes in place that help ensure Ernst & Young’s continued independence.

Audit Committee Oversight of Our Independent Registered Public Accounting Firm

Oversight includes regular executive sessions with Ernst & Young, discussion with Ernst & Young about the scope of the audit, a comprehensive annual evaluation when determining whether to reengage Ernst & Young and direct involvement by the Audit Committee and its chair in the selection of the engagement partner in connection with the mandated PCAOB partner rotation rules.

Based on this evaluation, the Audit Committee and the Board believe that retaining Ernst & Young to serve as our independent registered public accounting firm for 2025 is in the best interests of the Company and its shareholders.

Fees

Fees billed to the Company by Ernst & Young for the years ended December 31, 2024 and 2023 are as follows:

Type of Fees |  | 2024 |  | 2023
Audit fees (1) |  |  | $2,230,800 |  |  |  | $1,940,000 |
Audit-related fees (2) |  |  | 42,180 |  |  |  | 37,000 |
Tax compliance/preparation fees (3) |  |  | 243,825 |  |  |  | 240,666 |
Tax consulting fees (4) |  |  | 34,225 |  |  |  | 7,825 |
All other fees |  |  | — |  |  |  | — |
Total: |  |  | $2,551,030 |  |  |  | $2,225,491 |

(1)
Audit fees for the audit of our annual financial statements and internal controls over financial reporting, the review of our interim financial statements and for work on securities offerings and other filings with the SEC, including comfort letters, consents and comment letters.
(2)
Fees for audit-related services include services associated with legally required employee benefit plan audits and subscriptions to online accounting and tax information services.
(3)
Tax compliance/preparation fees are incurred for the review or preparation of tax returns, claims for refunds and tax payment compliance.
(4)
Tax consulting fees relate primarily to tax planning advice incident to acquisitions, dispositions, developments, financings and similar issues.

Pre-Approval Policy

The Company’s Audit Committee has reviewed and approved the Company’s engagement of Ernst & Young as its independent registered public accounting firm, and the incurrence of all of the fees described above, for 2024 and 2023 and has selected Ernst & Young as the Company’s independent registered public accounting firm for 2025. The Audit Committee has also adopted an Audit and Non-Audit Services Pre-Approval Policy (the “Pre-Approval Policy”) for all other services Ernst & Young may perform for the Company in 2025. The Pre-Approval Policy details with specificity the audit and permitted non-audit services that are authorized within each of the above-described categories of services and provides for aggregate maximum dollar amounts for such pre-approved services. Any additional services not described or otherwise exceeding the maximum dollar amounts prescribed by the Pre-Approval Policy for 2025 will require the further advance review and approval of the Audit Committee.

Vote Required

The affirmative vote of holders of a majority of the votes cast in person or by proxy at the meeting at which a quorum is present is required to ratify the selection of Ernst & Young. If this proposal is not approved, the selection of the independent registered public accounting firm will be reconsidered by the Audit Committee and the Board. Because it is difficult and not cost effective to make any change in the independent registered public accounting firm so far into the year, the appointment of Ernst & Young would probably be continued for 2025 unless the Audit Committee or the Board finds additional good reasons for making an immediate change.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE SELECTION OF ERNST & YOUNG AS OUR independent registered public accounting firm FOR 2025.

## Proposal 3 – Approval of Executive Compensation

Each public company is generally required to include in its proxy statement a separate resolution subject to a non-binding shareholder vote to approve the compensation of the Company’s NEOs, as disclosed in its proxy statement, not less frequently than once every three years. This is commonly known as a “Say-on-Pay” proposal or resolution, and the Board currently intends for the Company to hold a non-binding, advisory “Say-on-Pay” vote every year.

In deciding how to vote on this proposal, the Board encourages you to read the “Compensation Discussion and Analysis” and “Executive Compensation” sections above for a detailed description of our executive compensation philosophy and programs and the compensation decisions the Compensation Committee has made under those programs.

The Board recommends that shareholders vote for the following advisory resolution:

RESOLVED, that the compensation of the NEOs, as disclosed in the Company’s Proxy Statement pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure, is hereby APPROVED.

Vote Required

The affirmative vote of holders of a majority of the votes cast in person or by proxy at the meeting at which a quorum is present is required for the approval of this advisory resolution. Although the vote on this advisory proposal is non-binding, the Compensation Committee and the Board value the opinion of shareholders and will take into account the outcome of the vote when considering future executive compensation decisions.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE ADVISORY APPROVAL OF OUR EXECUTIVE COMPENSATION.

## Purpose of the Annual Meeting

Shareholders will vote on the proposals presented at the Annual Meeting. YOUR VOTE IS VERY IMPORTANT. Please vote your shares in advance of the meeting, using one of the methods described below.

## Who Can Vote

You will be entitled to vote your shares on each proposal if you held your shares as of the close of business on March 31, 2025 (the “Record Date”). Each of the shares outstanding on that date is entitled to one vote on each proposal. As of the Record Date, a total of 379,840,678 common shares were outstanding and entitled to vote. We are making this Proxy Statement and our Annual Report available to shareholders electronically via the Internet at www.proxyvote.com. On April 17, 2025, we will begin mailing to our shareholders a notice containing instructions on how to access this Proxy Statement and our Annual Report and how to vote online. If you received that notice, you will not receive a printed copy of the proxy materials unless you request them by following the instructions for requesting such materials contained in the notice.

## Virtual Meeting Matters

The Annual Meeting will be conducted completely in a virtual meeting format, via live audio webcast. By hosting the Annual Meeting in a virtual format, the Company is able to provide the opportunity for participation by a wider group of our shareholders, while reducing costs. This approach also aligns with the Company’s broader sustainability goals. The virtual meeting has been designed to provide shareholders the same rights and opportunities to participate as they would have at an in-person meeting.

Access to the Audio Webcast. To attend the Annual Meeting, log in at www.virtualshareholdermeeting.com/EQR2025. You will need the 16-digit control number which appears on your proxy card, voting instruction form (“VIF”) or Notice Regarding the Availability of Proxy Materials (“Notice”). In the event that you do not have a control number, please contact your bank, broker or other nominee as soon as possible and no later than Thursday, June 19, 2025, so that you can be provided with a control number and gain access to the meeting. The Annual Meeting will begin promptly at 8:00 a.m. Central Time on Thursday, June 26, 2025. Online access to the audio webcast will open approximately 15 minutes prior to the start of the meeting, at 7:45 a.m. Central Time. We encourage shareholders to access the meeting and test the computer audio system prior to the start time.

Submitting Questions. As part of the Annual Meeting, we will hold a live, online Q&A session, during which we intend to answer questions submitted during the meeting in accordance with the Annual Meeting’s Rules of Conduct that are pertinent to the Company and the meeting matters, as time permits. Questions and answers will be grouped by topic and substantially similar questions will be grouped and answered once. In order to ensure all shareholders are responded to, we will limit each shareholder to one question. Shareholders of record at the close of business on the Record Date may submit questions in writing during the Annual Meeting via the meeting website. Detailed guidelines for submitting written questions during the meeting are available at www.virtualshareholdermeeting.com/EQR2025.

Technical Assistance. If you encounter any difficulties accessing or participating in the virtual Annual Meeting, please call the technical support number that will be posted on the Annual Meeting website log-in page.

Information About the Annual Meeting

## How to Vote

Your vote is important and we encourage you to vote promptly. Internet and telephone voting are available 24 hours a day until 11:59 p.m. (Eastern Time) on June 25, 2025, and using either method you will be able to confirm that the vote of your shares has been properly recorded. You may vote in the following ways:

By Internet. You may vote your shares via the Internet at www.proxyvote.com using the control number shown on your Notice, proxy card or VIF. If you vote by Internet, you do not need to return your proxy card or VIF.

By Telephone. You may vote your shares by calling 1-800-690-6903 and using the control number shown on your Notice, proxy card or VIF. If you vote by telephone, you do not need to return your proxy card or VIF.

By Mail. If you are a shareholder of record and received a paper set of materials, you may vote by returning a completed and signed proxy card by mail. If you are a beneficial owner with shares held by a broker, you may vote by returning a completed and signed VIF.

At the Annual Meeting. If you are a shareholder of record or beneficial owner and decide to attend the Annual Meeting virtually, you may vote at www.virtualshareholdermeeting.com/EQR2025 during the meeting. You will be required to use the control number shown on your Notice, proxy card or VIF.

## Quorum for the Meeting

The presence at the meeting in person or by proxy of the holders of a majority of the common shares outstanding on the Record Date will constitute a quorum permitting business to be conducted at the meeting. If you have returned valid proxy instructions or attend the meeting and vote via the Annual Meeting website, your shares will be counted for purposes of determining whether there is a quorum, even if you abstain from voting on any or all matters introduced at the meeting.

## Beneficial Ownership

If your shares are registered directly in your name with the Company’s transfer agent, Computershare, Inc., you are the “shareholder of record” of those shares. A Notice with instructions on how to vote your shares has been provided directly to you by the Company. If your shares are held in “street name” by a broker, you are considered the “beneficial owner” of those shares. You will receive instructions from your broker on how to vote your shares. Other than for Proposal 2, brokers do not have the authority to vote on the proposals unless they have received voting instructions from you. Accordingly, if you do not provide your broker with voting instructions, your shares for Proposals 1 and 3 will not be voted. When a bank, broker or other nominee is unable to vote shares for this reason, it is called a “broker non-vote.”

## Revoking/Changing Your Proxy

You may change or revoke your proxy at any time before the meeting by timely delivery of a properly executed, later-dated proxy (including an Internet or phone vote) or by voting via the Annual Meeting website. The powers of the proxy holders with respect to your shares will be suspended if you attend the meeting and so request, but attendance at the meeting will not by itself revoke a previously granted proxy.

## Managing the Number of Proxy Statements and Annual Reports

To reduce our printing costs and postage fees, the Company adopted a procedure called “householding” which provides that shareholders who have the same address and last name will receive only one Notice, and if paper copies have been requested, only one copy of this Proxy Statement and the Annual Report, unless the Company has received contrary instructions from one or more of the shareholders. If you no longer wish to receive hard copies or multiple copies, or would prefer to receive separate copies of the Notice, Proxy Statement or Annual

Voting results of the Annual Meeting will be disclosed on a Current Report on Form 8-K filed with the SEC within four business days after the Annual Meeting, which will be accessible on the Company’s website at www.equityapartments.com in the Investor section under “Filings – SEC Filings.”

## Votes Required and Effect of Abstentions and Broker Non-Votes

1. | Election of Trustees | Votes cast FOR a nominee exceed votes AGAINST that nominee. | Not counted as votes cast; no impact on outcome.
2. | Ratification of Ernst & Young LLP as the Company’s Independent Registered Public Accounting Firm | Approval by a majority of the votes cast, in person or by proxy, at the meeting. | Abstentions not counted as votes cast; no impact on outcome. No broker non-votes on this matter.
3. | Approval of Executive Compensation | Approval by a majority of the votes cast, in person or by proxy, at the meeting. | Not counted as votes cast; no impact on outcome.

## Proxy Solicitation

The cost of the solicitation of proxies will be borne by the Company. The Company has hired MacKenzie Partners, Inc. to assist in distributing and soliciting proxies and will pay approximately $17,500, plus expenses for these services.

## Other Matters

The Board knows of no other matters to be presented for shareholder action at the Annual Meeting. If any other matters are properly presented at the meeting for action, it is intended that the persons named in the proxies will vote upon such matters in accordance with their discretion.

## Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires those who are trustees, executives and/or beneficial owners of more than 10% of the Company’s outstanding common shares to file reports of ownership and changes in ownership with the SEC. We believe that no such person failed to file any such report or to report any transaction on a timely basis during 2024, except that Mr. Brackenridge inadvertently filed a Form 4 two days late in April 2024 reporting a single sale of shares that was made by a third-party investment advisor pursuant to Mr. Brackenridge's Rule 10b5-1 trading plan.

## Contacting the Board of Trustees

The Board welcomes your questions and comments.

In accordance with our Bylaws as currently in effect, for a shareholder to nominate a trustee or for a proposal of a shareholder to be presented at the Company’s 2026 Annual Meeting, other than a shareholder proposal intended to be included in our proxy statement and submitted pursuant to Rule 14a-8 of the Act, shareholder proposals must be received at our principal executive offices not earlier than November 16, 2025 and not later than 5:00 p.m., Central Time, on December 16, 2025.

See “Governance of the Company – Board Composition and Trustee Nomination Procedures.” Shareholders who intend to solicit proxies in support of trustee nominees other than the Company's nominees must also comply with the additional requirements of Rule 14a-19(b) of the Act.

Acquisition Capit alization Rate or Cap Rate. NOI that the Company anticipates receiving in the next 12 months (or the year two or three stabilized NOI for properties that are in lease-up at acquisition) less an estimate of property management costs/management fees allocated to the project (generally ranging from 2.0% to 4.0% of revenues depending on the size and income streams of the asset) and less an estimate for in-the-unit replacement capital expenditures (generally ranging from $100-$450 per apartment unit depending on the age and condition of the asset) divided by the gross purchase price of the asset. The weighted average Acquisition Cap Rate for acquired properties is weighted based on the projected NOI streams and the relative purchase price for each respective property.

Capital Exp enditures to Real Estate:

Building Improvements. Includes roof replacement, paving, building mechanical equipment systems, exterior siding and painting, major landscaping, furniture, fixtures and equipment for amenities and common areas, vehicles and office and maintenance equipment.

NOI-Enhancing. Primarily includes Renovation Expenditures as well as sustainability and property-level technology expenditures that are intended to increase revenues or decrease expenses.

Recurring. Capital expenditures necessary to help preserve the value of and maintain the functionality at our apartment properties.

Renovation Expenditures. Apartment unit renovation costs (primarily kitchens and baths) designed to reposition these units for higher rental levels in their respective markets.

Replacements. Includes appliances, mechanical equipment, fixtures and flooring (including hardwood and carpeting).

Dispos ition Yield. NOI that the Company anticipates giving up in the next 12 months less an estimate of property management costs/management fees allocated to the project (generally ranging from 2.0% to 4.0% of revenues depending on the size and income streams of the asset) and less an estimate for in-the-unit replacement capital expenditures (generally ranging from $150-$450 per apartment unit depending on the age and condition of the asset) divided by the gross sales price of the asset. The weighted average Disposition Yield for sold properties is weighted based on the projected NOI streams and the relative sales price for each respective property.

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.

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.
