VISION
We are an inspired, engaged and collaborative team committed to providing extraordinary service to our residents, customers and each other.
CULTURE
Live the Golden RuleDo the right thingWe over me
Treat others the way you want to be treated – we don’t just practice it, we live it. The exceptional experiences we deliver wouldn’t be possible without understanding our impact on others. We operate with respect, empathy and consideration at all times. It’s not a suggestion, it’s our moral obligation.We choose honesty and integrity in all our actions, making the best, most educated decisions we can. Sometimes the right thing is the easy thing, or the popular thing. Other times it isn’t. We don’t get sidetracked when things go wrong, and we don’t shy away from doing what is right.We work as a collaborative and collective unit. No one person operates alone, and we keep the wider team in mind when making decisions about individual work. We know we need each other to produce an unmatched experience for our residents and customers. What’s more, we trust each other enough to sacrifice our own goals for those of the team.
Nothing changes if nothing changesMindset is everythingKeep it simple
Mindset is the guiding force behind all our actions. We can’t always decide what happens to us, but we can always decide how to handle it. Bad experiences don’t bring down our whole day. We learn, we grow and we become resilient. We are successful because we choose to be, every day and every step of the way.Let’s not overcomplicate things. Can a clearer word explain your point? Use it. Can fewer steps streamline your work? Do it. We lead with what is most important, shedding complexity as we go. Simplicity isn’t effortless, but it does make things a bit easier.
We don’t sit still for long. We are constantly transforming both our industry and our company. That means we are open and flexible, using what works now to develop what works next. Even if it ain’t broke, we still make it better. Lots of folks will say it hasn’t been done – we say it hasn’t been done yet.
Be yourself & thrive
Inclusion, diversity, equity and accessibility are at the heart of who we are and what we do. Our biggest competitive advantage is the variety of individual perspectives we all bring to Sun. We support and celebrate what makes us unique, creating a space where all can succeed.

Dear Fellow Shareholders,
2023 marked our 30th year as a public company and we are incredibly proud of the best-in-class portfolio we have created and of the talented Sun team members who operate it. With 667 properties comprising nearly 180,000 developed sites and approximately 48,000 wet slips and dry storage spaces in the U.S., Canada and the United Kingdom ("UK"), we are the largest publicly traded owner-operator of manufactured housing ("MH") and recreational vehicle ("RV") communities, and marina properties. The compelling supply and demand fundamentals that underpin MH, RV and marinas, combined with Sun’s unmatched operational platform, generated another year of strong property-level results. On the demand side, the number of people needing quality, well-located, attainably priced housing, as well as the large number of RV and boat owners, represent a demand base that vastly exceeds the supply of available sites and slips. Meanwhile, there is very limited new supply due in part to zoning and other regulatory considerations.
These market conditions, combined with our high-quality properties and operational excellence, make our business highly resilient, a fact we have demonstrated by generating over 20 years of positive same-property NOI growth through economic cycles. We remain focused on our best-in-class portfolio and team, and simplifying our operations to position Sun for steady earnings growth.
Strong core NOI growth
During 2023, Sun achieved another year of strong property-level results, with total Same Property NOI increasing 7.3% over 2022, driven by a 6.2% increase in real property revenue and property expense growth of 4.2%. MH Same Property NOI, which represents roughly 53% of total Same Property NOI, grew 6.8% over the prior year. Same Property RV NOI represents 26% of total Same Property NOI and grew 4.8% during the year.
During 2023, MH and RV Same Property blended occupancy, which adjusts for the delivery and lease-up of expansion sites, increased by 230 basis points to end the year at 98.9%. The increase was largely driven by transient to annual RV site conversions of more than 2,100 sites. Since the start of 2020 when we began to strategically focus on transient-to-annual RV site conversions, we have completed nearly 7,000 conversions, representing a 24% increase in the number of annual sites. We expect to continue growing occupancy through additional transient site conversions and through select, accretive expansion activity.
Marina Same Property NOI increased by 11.7% during 2023, exceeding our expectations. Demand to access our unparalleled network of marinas remains strong, and at year end approximately 89% of our marinas had a wait list for at least one slip size.
In the UK, real property NOI was in line with our expectations, demonstrating the strong value proposition our holiday parks represent. The value of owning a holiday home in a Park Holidays property was demonstrated by the average resident tenure increasing to approximately eight years. Demand for UK home sales showed signs of stabilizing during the second half of the year. UK homes sales and margins were in line with our guidance, which reflected certain economic headwinds, including higher inflation and interest rates. Looking ahead to 2024, we anticipate the UK’s 2023 results represent a solid foundation from which to grow.
Sharpening our focus and simplifying our story
From 2010 through 2022, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV and marina properties. With the benefit of our expanded portfolio, we have now shifted our strategy toward optimizing the value of our existing businesses through achieving strong rental rate growth and operating efficiencies. We remained disciplined in pursuing only the most strategic and synergistic new acquisition and expansion opportunities.
2024 Proxy Statement
1


To simplify our business and reduce leverage, we have made strong progress toward monetizing assets no longer deemed to be strategic. We resolved the UK note and we now have the experienced Park Holidays team managing all assets we own in the UK. We sold our investment in the common stock of Ingenia, an owner/operator of MH and RV communities in Australia, recycled capital out of our consumer loan receivables portfolio, divested our interest in Campspot, and meaningfully reduced the number of properties owned in joint ventures, using the proceeds to pay down debt. During the first two months of 2024, we reduced our floating rate debt exposure further with proceeds from a $500 million unsecured bond offering and from closing on the sale of two MH properties.
Advancing our ESG platform
Throughout 2023, we demonstrated our ongoing commitment to ESG through increases in learning & development hours, volunteerism and investor engagements. We expanded our environmental reporting to be inclusive of all material direct and indirect impacts from our operations. With these expansions, and our ESG priorities for 2024, we aim to set our carbon goal baseline in 2025.
2024 and beyond
As we move further into 2024, our primary goals are to continue simplifying our operations to harness the earnings power of our portfolio, and to continue strengthening our investment grade balance sheet. By remaining disciplined in pursuing new acquisitions and developments, further deleveraging, and maximizing the efficiency of our operating platform, we are confident in Sun’s strategic position to accelerate earnings growth in the coming years.
Thank you
As a valued member of the Sun community, we hope you share our pride in our many accomplishments, as well as our excitement for our continued achievement. Thank you for your continued support.
Sincerely,

NOTE ON NON-GAAP MEASURES
This document includes information about certain non-GAAP supplemental performance measures that we use as key measures of the Company’s performance and for other purposes, such as to assist in determining the compensation of our NEOs. These non-GAAP measures include FFO, NOI and EBITDA, and derivations of such measures, including Core FFO, Core FFO per Share, Recurring EBITDA, Same Property NOI and TTM Recurring EBITDA. We believe these non-GAAP measures are appropriate given their wide use by and relevance to investors and analysts following the real estate industry. See Appendix A for more detail on these terms and reconciliations of these non-GAAP financial measures to GAAP measures.
2023 REVIEW
The strong Same Property NOI growth we generated across all segments in 2023 continued to demonstrate the resiliency of our best-in-class portfolio. Our 2023 Core FFO per Share of $7.10 was in-line with our expectations and, based on five-year and 10-year TSRs, our common stock outperformed many of the leading real estate and market indices. As importantly, during 2023 we completed transactions and capital recycling opportunities that simplified our operations and positioned our Company to deliver reliable earnings growth going forward.

Spotlight on Engaging Team Members in Volunteerism
We over me is one of Sun’s seven core culture statements, and we enjoy living it every day by using our time, talent and treasures to strengthen the communities in which we operate and live. We track the volunteer hours recorded by our team members each year as a tangible metric that quantifies how deep and wide the We over me culture has permeated our company. The 73% increase in reported volunteer hours by Sun team members in MH, RV and Marina locations in North America in 2023, was a testament to the success of Sun’s approach to empowering local teams and pairing them with the resources and leadership support to pursue volunteerism.
We attribute the recent increase in volunteer hours in part to the Sun Unity program. This program focuses on driving volunteerism across all levels of our Company, rather than from senior leadership, by creating and promoting peer-driven volunteer opportunities. Ambassadors work with local community members, nonprofits, and their regional leaders to identify the needs of their area and then determine how Sun can contribute its resources and people to create positive change.
Spotlight on Supplier ESG Assessment
During 2023, our ESG and Sourcing Teams piloted an assessment of our major suppliers’ ESG practices and commitments. The assessment included 10 key suppliers to our North American MH and RV properties. The assessments reviewed alignment to Sun’s Code of Vendor and Supplier Conduct and availability of potential ESG metrics from our supply chain. The assessment found that all 10 suppliers were in compliance with all elements of our Code of Vendor and Supplier Conduct, which includes policies governing human rights and labor practices as well as pursuing environmental best practices.
We intend to expand the assessment to additional key suppliers within our entire portfolio in 2024.

SUMMARY
What Am I Voting On?
Ten directors will be elected at the Annual Meeting. The NCG Committee evaluated each nominee in accordance with the committee’s charter and our Corporate Governance Guidelines and submitted the nominees to the Board for approval. Except for Jerome W. Ehlinger and Craig A. Leupold, who were appointed to serve as directors by the Board on February 15, 2024, through the Annual Meeting, all of the nominees were elected to the Board at the 2023 annual meeting. Each of the directors has served continuously from the date of his or her election or appointment to the present time.
Messrs. Ehlinger and Leupold were identified by the Company and appointed to the Board following constructive discussion the Company held with Land and Buildings Investment Management LLC, a shareholder of the Company, as part of a Board refreshment initiative. In addition, Ronald A. Klein will not stand for re-election. He will continue to serve on the Board of Directors until the date of the Annual Meeting, and one of the ten nominees, other than Mr. Ehlinger and Mr. Leupold, will resign or retire from the Board no later than December 31, 2024, as a result of the Board 's focus on refreshment.
The term of each of our directors expires at the Annual Meeting, and when his or her successor is duly elected and qualified or upon his or her earlier resignation or removal. Each director elected at the Annual Meeting will serve for a term commencing on the date of the Annual Meeting and continuing until our 2025 annual meeting of shareholders and until his or her successor is duly elected and qualified or until his or her earlier resignation or removal. In the absence of directions to the contrary, proxies will be voted in favor of the election of the ten nominees named below.
Vote Required
A majority of the votes cast at the Annual Meeting is required for the election of each director. Abstentions will not be counted in determining which nominees received a majority of votes cast since abstentions do not represent votes cast for or against a candidate. Brokers are not empowered to vote on the election of directors without instruction from the beneficial owner of the shares and thus broker non-votes likely will result. Because broker non-votes are not considered votes cast for or against a candidate, they will not be counted in determining which nominees receive a majority of votes cast. 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 of common stock to approve the election of any substitute nominee proposed by the Board.

The Board unanimously recommends that you vote “FOR” each of the ten nominees.

Proposal No. 1 – Election of Directors
CONSIDERATION OF DIRECTOR NOMINEES
Board Membership Criteria
The Board has established criteria for Board membership. These criteria include the following specific, minimum qualifications that the NCG Committee believes must be met by an NCG Committee-recommended director nominee for a position on the Board:
the candidate must have experience at a strategic or policy making level in a business, government, non-profit or academic organization of high standing;
the candidate must be highly accomplished in his or her field, with superior credentials and recognition;
the candidate must be well regarded in the community and must have a long-term reputation for high ethical and moral standards;
the candidate must have sufficient time and availability to devote to our affairs, particularly in light of the number of boards on which the candidate may serve; and
the candidate’s principal business or occupation must not be such as to place the candidate in competition with us or conflict with the discharge of a director’s responsibilities to us or to our shareholders.
In addition to the minimum qualifications for each nominee set forth above, the NCG Committee will recommend director candidates to the full Board for nomination, or present director candidates to the full Board for consideration, to help ensure that:
a majority of the Board shall be “independent” as defined by the NYSE rules;
each of its Audit, Compensation, and NCG Committees shall be comprised entirely of independent directors; and
at least one member of the Audit Committee shall have such experience, education and qualifications necessary to qualify as an “audit committee financial expert” as defined by the rules of the SEC.
Identifying and Evaluating Nominees
When the NCG Committee identifies qualified candidates and recommends director nominees to serve on the Board, the NCG Committee considers whether the Board has an adequate distribution and representation of relevant skills, backgrounds and experience. In addition to professional accomplishments and expertise, the Board may consider diversity of background, experience and thought in evaluating and recommending qualified candidates to serve on the Board. The NCG Committee and the Board believe that diversity (including diversity of gender, race and ethnicity) is highly important because a variety of ideas and points of view can contribute to more effective decision-making.
The NCG Committee may solicit recommendations for director nominees from non-management directors, executive officers, third-party search firms or any other source it deems appropriate. The NCG Committee will review and evaluate the qualifications of any proposed director candidate that it is considering or that has been recommended to it by a shareholder in compliance with the NCG Committee’s procedures, and conduct inquiries it deems appropriate into the background of these proposed director candidates. In evaluating proposed director candidates, the NCG Committee considers the following qualifications that it believes nominees should have:
proven real estate and / or REIT experience;
track record of strong management and leadership capabilities at a successful organization;
sufficient time to devote to Board responsibilities; and
independence from the Company and its current directors and employees.
When nominating a sitting director for re-election, the NCG Committee will consider the director’s performance on the Board and the director’s qualifications in respect to the criteria set forth above. Other than circumstances in which we are legally required by contract or otherwise to provide third parties with the ability to nominate directors, the NCG Committee will evaluate all proposed director candidates based on the same criteria and in substantially the same manner, with no regard to the source of the initial recommendation of the proposed director candidate.

Lewis and Arthur A. Weiss. Under our charter, each of our directors serves for a one-year term and until his or her successor is duly elected and qualified, or until his or her earlier resignation or removal.
Messrs. Ehlinger and Leupold were identified by the Company and appointed to the Board following constructive discussion the Company held with Land and Buildings Investment Management LLC, a shareholder of the Company, as part of a Board refreshment initiative. In addition, Ronald A. Klein will not stand for re-election. He will continue to serve on the Board of Directors until the date of the Annual Meeting, and one of the ten nominees, other than Mr. Ehlinger and Mr. Leupold, will resign or retire from the Board no later than December 31, 2024, as a result of the Board's focus on refreshment.
The Board is elected by our shareholders to oversee and provide guidance on the Company’s business and affairs. It is the ultimate decision-making body of the Company except for those matters reserved for shareholders by law or pursuant to the Company’s governing documents. The Board oversees management’s activities in connection with proper safeguarding of the assets of the Company, maintenance of appropriate financial and other internal controls, compliance with applicable laws and regulations and proper governance. The Board is committed to sound corporate governance policies and practices that are designed and routinely assessed to enable the Company to operate its business responsibly, with integrity, and to position the Company to compete more effectively, sustain its success and build long-term shareholder value.

Role of the Board of Directors
Board's Role in Oversight of Strategy
One of the Board’s primary responsibilities is oversight of management’s execution of the Company’s goals and objectives. Throughout the year, management and the Board review and discuss the Company's detailed strategic plans, including changes from previous strategic positions, market and economic outlook, industry and regulatory trends, areas of focus for each functional area, expected financial implications, potential stakeholder impacts, resource requirements, human capital development, and risk and stress test scenarios, among other topics.
The Board and its committees regularly receive updates from management and actively engage in discussions regarding execution of the Company’s strategy, variables impacting results and changes to the strategic plan.
In addition to its regularly scheduled Board and committee meetings and ongoing interaction with the management team, Board members periodically visit properties representing various geographies and asset types. The Board believes these on-site visits provide additional insight into the Company’s markets, operations, residents and guests, human capital management, technology usage and allocation of capital investments, and allow for better oversight of and more thoughtful input into the Company’s strategies.
Board’s Role in Oversight of Risk Management

The Board and committees of the Board, together with members of executive and senior management, regularly review risk management in key areas of our business including, but not limited to, financial, strategic, operational, technology and compliance matters. Management and the Company’s outside advisors also periodically meet with the Board and its committees to provide detailed updates on specific areas of risk oversight.
Additionally, the Board reviews the results of our ERM efforts and receives periodic ERM updates from the ERM Committee, as described below.

The NCG Committee oversees succession planning for both the Board and CEO, routinely obtaining input from and updating the full Board on succession plan reviews. The NCG Committee also oversees succession planning and associate development of executive and senior management positions to ensure adequate bench strength is developed and available to meet the long-term needs of the Company. The CEO and other executive management periodically update the NCG Committee and the Board on senior management succession plans including associate development plans and areas of risk.
The Board has exposure to internal succession candidates on an ongoing basis, generally meeting with executives both inside and outside of Board meetings and also periodically meeting with key senior managers.

Oversight of Cybersecurity
Risk Management
Our business operations rely on the consistent availability of our communication platforms, enterprise applications, and related systems. We have implemented protocols to ensure the secure collection, storage, and transmission of data and invest in the development and enhancement of controls designed to prevent, detect, and respond to unauthorized access, computer viruses, malware, data exfiltration and other threats.
We have established an Information Security Management Committee to manage information security in accordance with the ISO 27001:2013 standard to ensure the consistent application of security principles, policy statements, and controls. In adhering to this industry standard, we manage and mitigate material risks from threats to our systems and data by partnering with reputable, recognized security firms, and conducting ongoing internal and external information security audits, risk assessments, anti-phishing campaigns, penetration testing exercises, systems monitoring activities, employee training, and cyber incident response exercises. Company policies include standards and procedures for vulnerability management, business continuity planning, encryption of sensitive data, physical security, user access controls, vendor risk management, teleworking, mobile device management, and system monitoring.
Comprehensive contingency and recovery plans are in place to ensure the ongoing provision of services to customers in the event of a cybersecurity incident. These are tested on a regular basis against scenarios of varying degrees by both internal and external resources.
To manage vendor risk, we conduct ongoing risk assessments based on the vendor’s published Systems and Operational Controls (SOC) reports, information provided in vendor security questionnaires, and any publicly available information including ongoing litigation or external disclosures.
Governance
Senior leadership provides the Board of Directors with ongoing security updates, which include notable changes to program plans, changes to the risk environment, information regarding material incidents that may have occurred, third-party audit reports on recent assessments of our security controls, and details regarding forward-looking plans and strategies to mitigate cyber risk. The Audit Committee of the Board of Directors provides oversight and is responsible for assessing risks to our business, in accordance with its charter. The Audit Committee engages in regular conversations with senior leadership about our security systems in order to monitor and mitigate risks from cybersecurity incidents, in accordance with our security principles and protocols.
The Senior Vice President of Information Technology and the Director of Information Security bear direct responsibility for daily management of cyber risk. Oversight from the executive team, led by the Chief Administrative Officer, ensures strategic alignment. With a wealth of executive leadership spanning over 20 years in both public and private sectors, these individuals collectively possess more than 75 years of invaluable experience in information technology and security.
The Information Security Management Committee (ISMC) and ERM Committee meet regularly to provide oversight of cyber risk management functions. Committee composition includes members from cross-functional departments, including technology, innovation, human resources, accounting & finance, internal audit, operations, and executive management. Various members of these committees hold industry certifications representing expertise in information security risk and compliance management, including the Certified Information Technology Professional (CITP), Certified Information Systems Security Professional (CISSP), Certified Information Security Auditor (CISA), and Certified in Risk and Information Systems Control (CRISC) designations.
Oversight of Emergency Preparedness
We develop, maintain and walk through emergency preparedness plans that address risks associated with man-made and natural events such as hurricanes, earthquakes, floods, droughts, wildfires, data center disruption and workforce displacement. Contingency plans for disaster recovery and incident response plans are in place and are reviewed and updated on a recurring basis. We also conduct risk assessments at multiple levels in the organization to identify potential emergency scenarios (risk events) and evaluate actions necessary to mitigate the risk and implement them. We design workforce recovery capabilities into our technology infrastructure, tools and services, with the goal of ensuring a permanent, extended or temporary loss of our facilities does not significantly impact our operations. Executive management, department heads and personnel across the organization are regularly involved in our preparedness planning and implementations.

Corporate Governance
Board Structure
Leadership Structure
The Board and the NCG Committee assess and revise our leadership structure from time to time. The Board does not have a fixed policy regarding the separation of the offices of Chairman and CEO. The Board believes that it should maintain the flexibility to select the Chairman and its Board leadership structure, based on the criteria that it deems to be in the best interests of the Company and its shareholders. Mr. Shiffman currently serves as our Chairman, President and CEO. The Board believes that combining the Chairman and CEO positions is the right corporate governance structure for us at this time as it most effectively utilizes Mr. Shiffman’s extensive experience and knowledge regarding the Company and our industries, and provides for the most efficient leadership of our Board and the Company. The Board believes that Mr. Shiffman, rather than an independent director, is in the best position, as Chairman and CEO, to lead Board discussions regarding our business and strategy and to help the Board respond quickly and effectively to the many business challenges affecting the Company. The Board also believes that this structure is preferable because it allows one person to speak for, and lead, the Company and the Board, and that splitting the roles of Chairman and CEO may cause the Company’s leadership to be less effective.
Independence of Non-Employee Directors
Although the Board believes that it is more effective to have one person serve as our Chairman, President and CEO at this time, it also recognizes the importance of strong independent leadership on the Board. Accordingly, in addition to maintaining a significant majority of independent directors and independent Board committees, the Board appoints a Lead Independent Director on an annual basis to serve for a term of one year. Clunet R. Lewis is currently serving as Lead Independent Director. The Lead Independent Director calls and presides at the executive sessions of our independent directors, acts as a liaison between our management team and the Board and is responsible for identifying, analyzing and making recommendations to the Board with respect to certain strategic and extraordinary matters. The Board believes that its Lead Independent Director structure, including the duties and responsibilities described above, provides the same independent leadership, oversight, and benefits for the Company and the Board that would be provided by an independent Chairman.
The NYSE rules require that a majority of the Board consists of members who are independent. There are different measures of director independence under the NYSE independence rules and under the federal securities laws. The Board has reviewed information about each of our non-employee directors and determined that Tonya Allen, Meghan G. Baivier, Stephanie W. Bergeron, Jeff T. Blau, Jerome W. Ehlinger, Brian M. Hermelin, Ronald A. Klein, Craig A. Leupold and Clunet R. Lewis are independent directors. The independent directors meet on a regular basis in executive sessions without management participation. In 2023, the executive sessions occurred after many of the regularly scheduled meetings of the entire Board and may occur at such other times as the independent directors deem appropriate or necessary.

Corporate Governance
Compensation Policies and Practices as They Relate to Risk Management
The Compensation Committee has reviewed the Company's compensation policies and practices and believes that any risks arising from such policies and practices are not likely to have a material adverse impact on the Company. Additionally, the Compensation Committee reviewed the relationship between our risk management policies and practices and the various components of our NEOs' compensation.
For the base salary component, the Compensation Committee determined that the following limits the incentive for risky behavior that would have a material adverse effect on the Company: (a) base salary is relatively small compared to other components of the NEOs' total compensation; and (b) the NEOs and employees receive copies of both the Company's Employee Handbook and all governing documents which describe the required standards of personal and professional conduct, with which all NEOs and employees must comply with at all times.
For the annual incentive award component, the Compensation Committee determined that the following limits the incentive for risky behavior that would have a material adverse effect on the Company: (a) performance based annual incentive awards provide a balance between the short-term and long-term goals and objectives of the Company; and (b) annual incentive awards are awarded at the discretion of the Compensation Committee.
For the equity compensation component, the Compensation Committee determined that the following limits the incentive for risky behavior that would have a material adverse effect on the Company: (a) the Company’s governing documents, including the Stock Ownership Guidelines and Executive Compensation Recovery (Clawback) Policy, properly align shareholder interests with the interests of the NEOs; (b) the Compensation Committee establishes the grants and terms of the Company’s restricted stock; and (c) the Compensation Committee grants both time restricted and performance restricted awards to better align with the interest of the Company’s shareholders.
Additionally, Gary A. Shiffman, the Company’s Chairman of the Board, President and CEO, meets regularly with the Compensation Committee to discuss the Company’s compensation policies and practices. Additional steps the Company has taken include maintaining an anonymous hotline to report concerns, issues or potential violations of its code of conduct, company policies or laws.
Compensation Committee Interlocks and Insider Participation
Brian M. Hermelin, Ronald A. Klein and Clunet R. Lewis served as members of the Compensation Committee of our Board during 2023. None of the members of the Compensation Committee have been, or will be, one of our officers or employees. We do not have any interlocking relationships between our executive officers and the Compensation Committee and the executive officers and compensation committees of any other entities, nor has any such interlocking relationship existed in the past.

Underwood, the CEO of Safe Harbor.
Other Board Policies and Processes
Board Evaluations
The Board believes annual performance reviews are essential for ensuring overall effectiveness, including fulfillment of its oversight responsibilities, strategic planning and communications. For 2023, the Board evaluation process was executed through detailed questionnaires. The NCG Committee administered Board wide questionnaires, reviewed the results of the evaluations and the recommendations and shared its findings with the Board to help direct the Board's activities and governance in the following year. In addition, each committee of the Board administered and performed its own review of the annual committee self-assessment to help direct the committees' activities and governance in the following year.

The results of the annual committee's self-assessment are reviewed by the committee to help direct committees' activities and governance in the following year.
Certain Relationships and Related Party Transactions
Policies and Procedures for Approval of Related Party Transactions
None of our executive officers or directors (or any family member or affiliate of such executive officer or director) may enter into any transaction or arrangement with us that reasonably could be expected to give rise to a conflict of interest without the prior approval of the NCG Committee.
Any such transaction or arrangement must be promptly reported to the NCG Committee or the full Board. Any such disclosure provided by an executive officer or director is reviewed by the NCG Committee and approved or disapproved.
In determining whether to approve such a transaction or arrangement, the NCG Committee takes into account, among other factors, whether the transaction was on terms no less favorable to us than terms generally available to third parties and the extent of the executive officer’s or director’s involvement in such transaction or arrangement.

OVERVIEW
Gary A. Shiffman, who is our Chairman, President and CEO, receives no additional compensation for his service as a director. The discussion below pertains to our non-employee directors.
Compensation Processes
Our Compensation Committee annually assesses the total compensation for non-employee directors relative to the compensation provided by similarly sized REITs and by our peer group. The Compensation Committee benchmarks our director compensation to that of our peers by comparing the aggregate total compensation of all of our non-employee directors to the aggregate total compensation of all of the non-employee directors of each of our peers. We believe the aggregate total compensation of all of our directors is more relevant to the interests of our shareholders than per-director compensation.
In 2023, the Compensation Committee, as part of its review of director compensation, made no change to the directors' cash fee structure or the Committees' fees. The Compensation Committee believes that the director compensation is fair, reasonable and in line with that of our peers and remains appropriate to incentivize directors to maximize shareholder value.
In an effort to align the interests of the Board with those of its shareholders, the Company’s directors are subject to a Stock Ownership Guideline Policy. Under this policy, as of December 31, 2023, each director who has been with the Company for more than five years was required to own shares of our stock with a value equal to eight times his or her annual Board cash retainer (exclusive of committee and Lead Independent Director fees). As of December 31, 2023, the value of average company stock ownership by the Company’s non-employee directors was 31 times the amount of the Board annual cash retainer, and each then-serving director was in compliance with the policy.
The Company also monitors its total director compensation expense, as a function of various company metrics, to assure that the total expense is consistent with the Company’s growth and overall shareholder value. The total director compensation expense, as compared to the Company’s total market capitalization, at year end, is a relevant factor to shareholder interests. From 2018 to 2023 the total director compensation as a percentage of the Company’s total market capitalization has declined by 20%.

Director Stock Ownership Guidelines
In an effort to align the interests of the Company’s management with those of its shareholders, the Company has adopted a policy under which its non-employee directors are subject to equity ownership guidelines. Under these guidelines, each director is required to:
Own shares of our stock with a value equal to eight times his or her annual cash retainer (exclusive of chair or committee fees).
Achieve compliance with these guidelines by five years from the later of: (i) November 2, 2021, which was the date these guidelines were last amended or (ii) the date he or she becomes a director.
Retain at least 50% of all shares of restricted stock as they vest (not including any newly vested shares sold or withheld to pay applicable taxes) until he or she complies with the guidelines, or if he or she fails to comply due to a reduction in our stock price.
As of March 18, 2024, each of our non-employee directors was in compliance with the stock ownership guidelines.

The following proposal, commonly known as a “say-on-pay” proposal, gives shareholders the opportunity to approve, reject or abstain from voting with respect to our fiscal 2023 executive compensation programs and policies and the compensation paid to our NEOs listed in the Summary Compensation Table below.
Shareholders are being asked to approve the following resolution at the Annual Meeting:
“RESOLVED, that the compensation paid to our NEOs, as disclosed pursuant to the SEC’s rules and regulations, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion, is hereby approved on an advisory basis.”
As discussed in the “Compensation Discussion and Analysis” section below, the primary objectives of our executive compensation program are to attract and retain a skilled executive team to manage, lead and direct our personnel and capital to obtain the best possible economic results. The compensation of our executive officers reflects the success of our management team in attaining certain operational goals, which leads to the success of the Company and serves the best interests of our shareholders.
This proposal allows our shareholders to express their opinions regarding the decisions of the Compensation Committee on the prior year’s annual compensation to the NEOs. Your non-binding advisory vote will serve as an additional tool to guide the Board and the Compensation Committee in continuing to improve the alignment of our executive compensation programs with our interests and the interests of our shareholders and is consistent with our commitment to high standards of corporate governance.

Proposal No. 2 – Non-Binding Advisory Vote to Approve Named Executive Officer Compensation
Vote Required
Advisory approval of this say-on-pay proposal requires the affirmative vote of holders of a majority of all the votes cast at the Annual Meeting. Abstentions will not be counted as votes cast for the say-on-pay proposal and do not represent votes cast for or against the advisory approval of the proposal. Brokers are not empowered to vote on the say-on-pay proposal without instruction from the beneficial owner of the shares and thus broker non-votes likely will result. Since broker non-votes are not considered votes cast on the say-on-pay proposal, they will not be counted in determining whether the say-on-pay proposal is approved. Because the vote on this proposal is non-binding and advisory in nature, it will not affect any compensation already paid or awarded to any NEO and will not be binding on or overrule any decisions by the Board; it will not create or imply any additional fiduciary duty on the part of the Board; and it will not restrict or limit the ability of shareholders to make proposals for inclusion in proxy materials related to executive compensation. To the extent there is any significant vote against our NEO compensation as disclosed in this Proxy Statement, the Compensation Committee will evaluate whether any actions are necessary to address the concerns of shareholders. The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our NEOs, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Compensation Discussion and Analysis
EXECUTIVE SUMMARY
The goals and objectives of our executive compensation program are to attract and retain a skilled executive team to manage, lead and direct our personnel and capital resources to achieve the best possible economic results, and to provide outsized TSRs to our investors. Our executive officers are compensated based on pay for performance and alignment with shareholders’ interests.
During 2023, we continued to demonstrate the resiliency of our best-in-class portfolio through our ability to generate reliable, strong Same Property NOI growth across all segments, and by achieving full year Core FFO per Share of $7.10, which was in line with our expectations. Total Same Property NOI (MH, RV and Marina) as compared to 2022 grew 7.3% (6.8% for MH, 4.8% for RV and 11.7% for Marina) during 2023, driven by a 6.2% increase in real property revenues and operating expense growth of 4.2%. Occupancy gains contributed to our strong operating results; the 3,268 Revenue Producing Sites we added during the year represented an 11.8% increase over the prior year gains. Same Property blended occupancy for MH and RV was 97.9% at December 31, 2023, up 50 basis points from year-end 2022. Adjusting for expansion sites delivered and leased, Same Property adjusted blended occupancy for MH and RV increased by 230 basis points year over year, to 98.9% at December 31, 2023. In addition, we effectively managed our balance sheet, capital resources and leverage by raising $836.9 million of fixed rate debt during 2023, using the proceeds to reduce floating rate debt.
From 2010 through 2022, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV and Marina properties. With the benefit of our expanded portfolio, during 2023 we shifted our strategy toward optimizing the value of our existing businesses through achieving strong rental rate growth and operating efficiencies. We remained disciplined in pursuing only the most strategic and synergistic new acquisition and expansion opportunities.
To simplify our business and reduce our exposure to variable rate debt, during the fourth quarter of 2023, we made strong progress toward monetizing assets no longer deemed to be strategic. We resolved the UK note receivable that we had put into receivership at the end of the third quarter of 2023, resulting in us taking ownership of three additional real estate assets. As a result, we now have the experienced Park Holidays team managing all assets we own in the UK. Additionally, we sold our investment in the common stock of Ingenia Communities Group (“Ingenia”), an owner / operator of MH and RV communities in Australia. We also recycled capital out of our consumer loan receivables portfolio, divested our interest in Campspot, and meaningfully reduced the number of properties owned in joint ventures, using the proceeds to pay down variable rate debt.
We achieved a 10-year TSR of 323.1% outperforming the MSCI U.S. REIT (“RMS”), Russell 1000, U.S. REIT Residential and S&P 500 indexes during the same period. In addition, we had a five-year TSR of 47.5%, outperforming the RMS and the Dow Jones all Equity REIT indices.

Compensation Discussion and Analysis
Performance Highlights
When determining compensation for the year ended December 31, 2023, the Compensation Committee took into account the level of achievement of certain key financial performance metrics, including but not limited to the following:
Financial Performance MetricRationale
Core FFO growth
FFO is a standard operating performance measure for REITs and is defined by Nareit as GAAP net income (loss), excluding gains (or losses) from sales of certain real estate assets, plus real estate related depreciation and amortization, impairments of certain real estate assets and investments, and after adjustments for nonconsolidated partnerships and joint ventures. Core FFO is a primary operating measure in our publicly-reported earnings results, and is defined as FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business.
Same Property combined NOI Growth - MH, RV & MarinaNOI is calculated by deducting direct property operating expenses from property operating revenues, thereby providing a measure of the actual operating performance of our properties. Same Properties are primarily those properties that we have owned and operated continuously since January 1, 2022.
Combined Operations / Sales CNOI - MH & RVNOI is calculated by deducting direct property operating expenses from property operating revenues, thereby providing a measure of the actual operating performance of our properties. CNOI excludes certain items that have been deemed to be outside of Mr. Thelen's control.
RPS Gains - MH & RVRevenue producing site gains represent the number of sites that we are able to fill during a period, net of the number of sites lost. By increasing Revenue Producing Sites, we increase our portfolio occupancy and can maximize generation of revenues and shareholder returns.
Development and expansion activitiesConstruction of ground-up developments and expansions of our existing communities provide for continued revenue growth through occupancy gains.
ESG initiatives
Performance is based on implementation and progress towards long-term commitments, including our DEI Roadmap, Carbon Neutral by 2035 and Net Zero Emissions by 2045, as well as integration of all business operations.
Individual goals / Compensation
Committee discretion
The Compensation Committee reviews each executive officer’s annual accomplishments in order to evaluate the specific contributions of each executive to our success and properly align pay and performance.

Compensation Discussion and Analysis
Exceptional Growth
Our leadership team has executed a series of acquisition and capital market transactions that have repositioned our portfolio. These activities have bolstered our strong and flexible balance sheet while generating significant growth in Core FFO per share and significant returns for our shareholders.
For over a decade, our executive team has executed on a strategic plan to deliver outsized results by utilizing our operational expertise to create a best-in-class platform of MH and RV communities with a broader geographic range and re-balancing our all-age and age-restricted holdings. Tactics our leadership has embraced include increasing our portfolio diversification by elevating our presence along the east coast of the U.S.; expanding west to California and Arizona; opportunistically entering the Marina business in 2020, and expanding our MH platform overseas with the acquisition of Park Holidays in the UK in 2022. Since 2020, our executive team has also focused on converting transient RV sites in order to grow MH and RV combined occupancy year over year, increase the percentage of real property rents derived from steady, annual lease income, and benefit from the higher operating margins associated with non-transient sites. Since 2020, the Company has converted nearly 6,900 transient RV sites, increasing its annual RV sites by nearly 25%.
In 2023, we shifted our strategy toward optimizing the value of our existing businesses. By focusing on realizing the consistent growth our portfolio generates, by remaining disciplined in pursuing external growth opportunities, and by further enhancing our investment grade balance sheet by deleveraging, our leadership is confident in our Company’s strategic positioning to re-accelerate Core FFO per Share growth.
During the last five years, we have acquired properties valued in excess of $7.5 billion as detailed in table below:

Total1185013496,445 $7,501.8 
Development and Expansion Activities
We have been focused selectively on property ground-up developments and expansion opportunities adjacent to our existing properties. During 2023, we deployed additional capital through the construction of ground-up development projects and expansion sites and acquisition of land for future development.
Ground-up Developments – We completed the construction of 360 MH and RV sites at five ground-up development properties. In total we have completed the development of 4,356 MH and RV ground-up development sites within the past five years.
Expansions – We expanded over 440 sites at 14 MH and RV properties in 2023. In total we have completed the development of 3,730 MH and RV expansion sites within the past five years. We continue to expand our properties by utilizing our inventory of owned and entitled land. We have approximately 17,980 MH and RV sites suitable for future development.
During the year ended December 31, 2023, we acquired four land parcels located in the U.S. and one land parcel in the UK for the potential development of over 1,350 sites for an aggregate purchase price of $35.8 million.

Compensation Discussion and Analysis
Strong and Flexible Balance Sheet
While optimizing our portfolio, we are also focused on maintaining a strong and flexible balance sheet. Through a series of capital market activities and with cash generated from operations, we have maintained conservative leverage levels, coverage ratios and liquidity as shown below:
Net Debt to Enterprise Value
7290
Net Debt to Recurring EBITDA
7321
Recurring EBITDA to Interest
7352
(1)Our Net Debt to Recurring EBITDA ratio for 2020 is elevated due to the acquisition of Safe Harbor late in 2020 which had the impact of including all of its debt and only two months of its EBITDA. Our ratio normalized during 2021 as Safe Harbor’s EBITDA is fully presented in our operating results.
(2)Net Debt to Recurring EBITDA ratio for 2021 does not factor a full year contribution from $1.4 billion of acquisitions completed during the course of 2021 and $705.4 million net proceeds received in 2022 from the settlement of outstanding forward sale agreements, which was used to repay borrowings outstanding under our senior credit facility, and for working capital and general corporate purposes.
(3)Net Debt to Recurring EBITDA ratio for 2022 does not factor a full year contribution of EBITDA from $2.2 billion of acquisitions completed during the course of 2022.
(4)Net Debt to Recurring EBITDA ratio for 2023 does not factor a full year contribution from $107.0 million of acquisitions completed during the course of 2023, but includes $53.9 million of secured borrowings on collateralized receivables, a transferred asset transaction which has been classified as collateralized receivables. The cash received from this transaction has been classified as a secured borrowing and remeasured at fair value. The cash received was used to repay borrowings outstanding under our senior credit facility.

Executive Compensation Highlights and Key Decisions
2023 Executive Compensation Program
Our executive compensation program is grounded in a compensation philosophy aimed at achieving strong alignment between executive compensation, the Company's long-term strategic goals and our shareholders’ interests.
The Compensation Committee considers the results of the non-binding advisory vote by shareholders on executive compensation, or the “say-on-pay” proposal, presented to shareholders at our 2023 annual meeting when evaluating our executive compensation program. The Compensation Committee made no direct changes to the Company’s executive compensation program as a result of the say-on-pay vote for the year ended December 31, 2023, as 84% of shareholders supported our 2022 executive compensation program. See the Advisory Vote on Executive Compensation section, under the Compensation Processes on page 84 for additional information.
When reviewing incentive structures, the Compensation Committee deeply values the continued interest of, and feedback from, our shareholders on our executive compensation program and is committed to ensure shareholder's perspectives are thoughtfully taken into account.

Compensation Discussion and Analysis
Annual Incentive Performance Metric - Marc Farrugia
Mr. Farrugia serves as the Executive Vice President and Chief Administrative Officer of the Company. For the year ended December 31, 2023, the CEO reviewed Mr. Farrugia's overall responsibilities, his individual performance during the year, the Company’s performance or other criteria deemed relevant to the Compensation Committee, and the annual incentives of the other executive officers and Mr. Farrugia's overall compensation, and made a recommendation of Mr. Farrugia's incentive compensation to the Compensation Committee. The Compensation Committee considered the CEO's recommendation and independently reviewed Mr. Farrugia's performance and exercised its sole discretion in awarding incentive compensation to Mr. Farrugia.
Total Shareholder Return
We outperformed the S&P 500, the MSCI U.S. REIT (RMS), the Russell 1000, U.S. REIT Residential and S&P 500 indices on 10-year TSRs. We stand out as a leader among REITs for delivering TSR results. We also produced a five-year TSR of 47.5%, outperforming the MSCI U.S. REIT (RMS) and the Dow Jones all Equity REIT indices. These results are indicative of our executive team’s strategic planning, leadership, execution and dedication to the Company. The execution of our strategic vision has resulted in prolonged TSR outperformance over time as evidenced in the charts below.

Chairman and CEO Compensation
In determining the compensation structure for Mr. Shiffman and his total compensation amount, the Compensation Committee takes into account many factors. As one of the longest-tenured CEOs in the REIT industry, Mr. Shiffman has delivered significant value to shareholders over a three-decade span. This is evidenced by the Company’s TSR over the period, which is 3,760%, among many other achievements.

Compensation Discussion and Analysis
An important aspect of Mr. Shiffman’s compensation package is the link between company performance and pay; our executives’ pay should be directionally aligned with the performance of the Company so that they are strongly incentivized to deliver shareholder value and financially rewarded for doing so. In 2023, 85% of Mr. Shiffman’s pay was awarded in the form of equity, and of that amount, 60% of the total number of restricted shares awarded was performance-based.

2021 - 2023 Market Equity Award - Grant Date Fair Value vs Realized Value
4947802450366
Consistent with prior practices, we remain committed to a highly oriented pay-for-performance equity program in which a majority of share grants continue to be tied to rigorous shareholder return-based goals. In light of headwinds faced by the Company in 2022 and 2023, our TSR was negative in both of those years, the second time in Mr. Shiffman’s tenure with two consecutive years of negative returns (the first being 2007-2008 during the Great Recession). As a result, Mr. Shiffman’s performance-based equity incentive award, granted in 2021, did not vest at December 31, 2023 (see chart above) and his 2023 pay is at its lowest level since 2019 (see the below chart). These are deliberate and logical outcomes of our stated alignment between pay and performance. In addition, the realized value of his equity awards will ultimately be lower than is reflected in the Summary Compensation Table if performance hurdles are not met. His cash bonus payout is also at its lowest amount since 2016.

Mr. Shiffman’s total compensation opportunity range for 2024 is at its lowest level in a decade. This decline is a result of the Compensation Committee's decision to reduce the number of equity incentive shares awarded to Mr. Shiffman from 75,000 in 2023 to 5,000 in 2024 (see chart below). In total, the decline from 2023 pay to the 2024 total compensation opportunity includes a reduction worth over $8.7 million entirely attributable to the reduction in the equity incentive awarded in 2024 relating to 2023 performance.

In setting the 2022 compensation elements and levels for the NEOs, the Compensation Committee considered several main compensation components including base salary, target annual non-equity incentive and long-term incentive awards (collectively “total remuneration”) on an actual and target basis, as well as per individual and in aggregate, across the team, as well as other factors. The Compensation Committee selected our peer group and similarly sized REITs to compare and benchmark our executive compensation based on a number of quantitative and qualitative factors including, but not limited to, revenues, total assets, market capitalization, industry, sub-industry, location, TSR history, executive compensation components and peer decisions made by other companies. Noting that the Company has only one publicly traded direct business peer of similar size, the Compensation Committee, in consultation with Ferguson Partners Consulting, LP ("FPC"), an executive compensation consulting firm engaged by us, strove to formulate our 2022 peer group of publicly traded companies that include the following characteristics: public manufactured housing REITs, industry and business strategies, size, operational intensity and complexity, competition and other considerations such as companies that cited us as a compensation peer, with an emphasis on relative size.

Compensation Discussion and Analysis
Additionally, in 2022, we engaged Alliance Advisors to assess the use of ESG linked metrics within senior management’s executive incentive plans. The analysis indicated that the adoption of ESG metrics in executive compensation programs at S&P 500 companies is now a widespread practice, as companies want to signal the importance of ESG priorities and be responsive to investor expectations. Most companies in the real estate sector tie ESG performance metrics to executive pay. Alliance Advisors reviewed proxy statements of a group of our compensation peers to assess the use of ESG linked metrics within senior management’s executive incentive plans. Of the 21 peers evaluated, the majority include at least one ESG metric within their executive compensation programs, with varying degrees of robustness. The majority of the metrics were qualitative in nature. Based on the above, the Compensation Committee felt comfortable with how the company uses ESG metrics in executive compensation decisions.
In setting the 2023 compensation elements, the Compensation Committee considered and relied on the above analysis. As part of its review of the 2023 executive compensation, the Compensation Committee reviewed executive compensation in comparison to the executive compensation provided by similarly sized REITs and our peer group, the Company's growth in market capitalization, revenues, and number of employees as well as the Compensation Committee's evaluation of the performance of the executive team in effectively implementing corporate growth strategies and driving shareholder value. The Compensation Committee made no change to the current compensation structure as the Compensation Committee believes that the current executive compensation is fair, reasonable and in line with that of similarly sized REITs and our peers, and remains adequate to appropriately incentivize our executives to maximize shareholder value.
2023 Annual Incentive Award
This represents the cash incentive awarded for 2023 performance and paid in 2024.
The annual incentive awards motivate the executive officers to maximize our annual operating and financial performance and reward participants based on annual performance. The Compensation Committee annually reviews performance measures for determining award levels, including growth in key metrics and individual goals. In each case, actual performance is measured against targets established by the Compensation Committee.
In setting the 2023 compensation elements and levels for the NEOs, the Compensation Committee made a change to the current compensation structure to better align executive compensation with that of similarly sized REITs and our peers, and ensure it remains adequate to appropriately incentivize our executives to maximize shareholder value. The Compensation Committee slightly modified the weighing of the elements of the annual incentive award, allocating more weight to corporate performance metrics and reducing the weight of individual goals. As a result, the Compensation Committee increased the weight of the corporate performance goals from 75% to 85% and decreased the weight of the individual goals from 25% to 15%.
The Compensation Committee, in its sole and absolute discretion, reserves the right to make adjustments to calculated results for certain transactions and other extraordinary matters, including but not limited to, acquisitions, divestitures, debt and equity transactions and other capital or unusual transactions, which may have an unexpected adverse or beneficial impact, when determining achievement of that performance target.

Mr. Thelen’s primary responsibility is to oversee the operations and home sales within the Company’s MH and RV communities. His annual incentive award for 2023 was based on his 2023 overall performance, as measured against goals and objectives set for him and his contribution to the Company's success, as determined by the Compensation Committee.

Annual Incentive Award Results
Corporate Performance Goals and Results
When setting corporate performance goals, the Compensation Committee considers factors relevant to current year expectations. Financial results from prior years may be used as a reference point, but the Compensation Committee focuses on setting rigorous annual goals that reflect current business conditions and expectations which will result in an appropriate pay for performance outcome for the specific year.
Core FFO growth and Same Property NOI growth targets are evaluated each year in relation to our budgets and related guidance communicated to the marketplace. Targets are set based on low-, mid- and high-levels of expected performance. In 2023, the Company generated Core FFO per Share of $7.10, despite inflationary pressures and higher interest rates. The Company also achieved strong Same Property Combined (MH, RV and Marina) NOI growth of 7.3% (6.8% for MH, 4.8% for RV and 11.7% for Marina), due to the compelling fundamentals of constrained supply and resilient demand that underpin the Company’s MH, RV and Marina businesses, bolstered by the operational excellence of the Company's property management teams.
The Compensation Committee sets a range of activity that is reasonably expected to be achieved in a normal operating year. The Compensation Committee took into consideration all then known facts in setting the 2023 corporate performance goals. From 2010 through 2022, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV and Marina properties. In 2023, with the benefit of our expanded portfolio, we shifted our strategy toward optimizing the value of our existing businesses through achieving strong rental rate growth and operating efficiencies. During 2023 and in order to further align leadership with shareholders, the Compensation Committee removed the MH and RV investment activity metric from the predefined 2023 executive annual incentive plan for purposes of computing the 2023 cash incentive amount for Mr. Shiffman, Mr. Castro-Caratini, Mr. Thelen and Aaron Weiss.
ESG initiatives continue to be of significant focus within the Company, leading the Compensation Committee to place increased weighting on this performance metric during 2023. Our team continues to enhance our ESG protocols and reporting and during 2023 accomplished the following ESG achievements:
Provided education to team members and key supply chain partners on our Carbon Neutrality goals;
Improved the completeness of our GHG inventory with the addition of capital goods, investments, and fugitive emissions;
Generated 11,630 mwh of solar energy on site, a 44% year over year increase;
Completed an ESG assessment with 10 key suppliers;
Reported over 16,000 volunteer hours by team members, a 73% increase over 2022;
Increased overall learning and development hours by 19.7% over the prior year;
Participated in three voluntary ESG benchmarks;
Achieved a three-point improvement of our GRESB score; and
Held over 240 investor engagement meetings, a 37% increase from 2022.
While certain 2023 executive goals were set at levels below 2022 targets or actuals, they were viewed as rigorous. For example, while 2023 Core FFO growth was set at a materially lower level than the 2022 target, it was viewed as rigorous, and in fact, performance fell below the threshold and resulted in a zero payout for that metric.

2023 Long-Term Equity Incentive Awards
This represents the equity award for 2022 performance granted in 2023.
Long-term equity incentive awards are provided to the executive officers in order to increase their personal stake in our success and motivate them to enhance our long-term value while better aligning their interests with those of other shareholders. Equity awards are generally awarded in the form of restricted stock although stock options may also be utilized. The value of the restricted shares awarded is the price of a share of our stock as of the close of business on the grant date. On an annual basis the Compensation Committee reviews and approves the equity incentives to be issued to each of the executive officers for the prior year’s performance. There is no established target for long-term equity incentive awards for any of the executive officers. Rather, the Compensation Committee reviews this component of each executive officer’s total compensation on an annual basis. Our executive officers (as well as our employees that receive restricted stock awards) receive distributions on the restricted stock awards that have been granted to date, including restricted stock awards that have not vested.
Long-Term Equity Incentive Awards Structure
Long-term equity incentive awards focus on executive retention to provide longer-term motivation with the effect of linking stock price performance to executive compensation.

The Company must outperform the MSCI U.S. REIT Index by achieving relative performance at the 55th percentile to earn the target award
The Company utilizes an absolute TSR modifier whereby payouts are capped at target if our absolute TSR is negative
The equity incentive award granted during the current year is determined based on prior year performance. Equity incentive awards for current year performance will be granted next year (e.g., awards for 2022 performance were granted in 2023 and therefore included in 2023 summary compensation disclosure; awards for 2023 performance are granted in 2024 and therefore will be included in the 2024 summary compensation disclosure).
The equity incentive award is granted based on a 60/40 split with 60% of the value in market / performance-vesting restricted shares and 40% of the value in time-vesting restricted shares. Key metrics used for market / performance shares include TSR over three years relative to the MSCI REIT index (RMS).

Long-Term Incentive Awards Granted in 2023 (Based on 2022 Performance)
In February 2023, the Compensation Committee granted each of Mr. Shiffman, Mr. Castro-Caratini, Mr. Thelen, Mr. Farrugia and Aaron Weiss long-term incentive awards for their 2022 performance as detailed in the table below. In determining the long-term incentive awards, the Compensation Committee considered the overall financial performance of the Company during 2022, as well as the executive’s achievement of his individual goals and the implementation of the strategic goals of the organization. In particular, for the year ended December 31, 2022, we achieved five-year and 10-year TSRs of 73.1% and 396.9%, respectively, outperforming the S&P 500, the MSCI U.S. REIT (RMS), the Russell 1000, U.S. REIT Residential and the FTSE indices. Additional factors included, but were not limited to, Core FFO growth of 12.9% compared to 2021, Same Property combined NOI growth (MH, RV and Marina) of 5.8% (5.4% for MH and RVs and 7.7% for marinas), total revenue increase of 30.7% compared to 2021, and the acquisition and successful integration of 69 properties, totaling over 27,000 sites, wet slips and dry storage spaces, and sites for expansion valued at $2.2 billion, inclusive of Park Holidays, the second largest owner and operator of holiday parks in the UK.

2024 Long-Term Equity Incentive Awards (Based on 2023 Performance)
This represents the equity award for 2023 performance granted in 2024.
In February 2024, the Compensation Committee granted each of Mr. Shiffman, Mr. Castro-Caratini, Mr. Thelen, Mr. Farrugia and Aaron Weiss long-term incentive awards for their 2023 performance as detailed in the table below. In determining the long-term incentive awards, the Compensation Committee considered the overall financial performance of the Company during 2023, as well as the executive’s achievement of his individual goals and the implementation of the strategic goals of the organization. In particular, the Company achieved a 10-year TSR of 323.1%, outperforming the RMS, Russell 1000, U.S. REIT Residential and S&P 500 indices during the same period. We also produced a five-year TSR of 47.5%, outperforming the MSCI U.S. REIT (RMS) and the Dow Jones all Equity REIT indices. Additional factors included, but were not limited to, Core FFO per Share of $7.10 being in line with our expectations; strong total Same Property NOI growth of 7.3% driven by Same Property NOI growth of 6.8% for MH, 4.8% for RVs and 11.7% for marinas; and the successful execution of capital recycling strategy and business simplification strategies.

Compensation Discussion and Analysis
COMPENSATION PROCESSES
When determining levels of compensation, the Compensation Committee considers: (a) internal equity among executive officers; (b) market data for the positions held by these executives; (c) each executive’s duties, responsibilities and experience level; (d) each executive’s performance and contribution to our success; and (e) cost to us. The Compensation Committee exercises its independent discretion in reviewing and approving the executive compensation program as a whole, as well as specific compensation levels for each executive officer. Final aggregate compensation determinations for each fiscal year are made after the end of the fiscal year and after financial statements for the year become available. At that time, the Compensation Committee determines the annual incentive award, if any, for the past year’s performance, and makes decisions on awards of equity-based compensation.
Role of Executive Officers in Compensation Decisions
The Compensation Committee makes all decisions regarding the compensation of NEOs, including cash-based and equity-based incentive compensation programs. The Compensation Committee reviews the performance and determines the annual incentive compensation of the CEO. Together the Compensation Committee and the CEO review the performance of the other NEOs. The CEO can recommend certain compensation incentives, including equity award amounts, to the Compensation Committee, which can exercise its discretion in approving or modifying such recommendations for other NEOs.
Role of the Compensation Consultant
From time to time, we engage FPC, a nationally known executive compensation consulting firm specializing in the public REIT industry, to help us evaluate the elements and levels of our executive compensation, including base salaries, annual cash incentive awards and annual equity-based incentives for our NEOs, and to determine our peer group for examining executive compensation. All executive compensation services provided by FPC are conducted under the direction or authority of the Compensation Committee.
Use of Comparative Market Data in Compensation Decisions
In setting the 2022 compensation elements and levels for the NEOs, the Compensation Committee considered several main compensation components including base salary, target annual non-equity incentive and long-term incentive awards (collectively “total remuneration”) on an actual and target basis, as well as per individual and in aggregate, across the team, as well as other factors. The Compensation Committee selected our peer group and similarly sized REITs to compare and benchmark our executive compensation based on a number of quantitative and qualitative factors including, but not limited to, revenues, total assets, market capitalization, industry, sub-industry, location, TSR history, executive compensation components and peer decisions made by other companies.
Noting that the Company has only one publicly traded direct business peer of similar size, the Compensation Committee, in consultation with FPC, strove to formulate our 2022 peer group of publicly traded companies that includes the following characteristics, placing an emphasis on relative size:
Guiding Factors for Selecting SUI Peers
Public Manufactured Housing REITs
There are two other public REITs (only one of which is of similar size to the Company) that are classified by Nareit within the manufactured homes sub-sector of the FTSE Nareit Residential Index.
Industry and business strategyCompanies with similar business models, philosophies, and investment criteria, including companies that are classified within the broader FTSE Residential Index.
SizeCompanies which are similar in size and scope, with the primary measure being total capitalization (debt plus equity) and leasable units under management.
Operational intensity and complexityCompanies with a comparable number of leasing units administered and similar complexity of diverse business activities and geographic reach.
Competition
Companies that we compete with for executive talent, and companies that we compete with for investors and which key analysts name as a peer.
Other considerations
Companies that cite us as a compensation peer.

Compensation Discussion and Analysis
Additionally, in 2022, we engaged Alliance Advisors to assess the use of ESG linked metrics within senior management’s executive incentive plans. The analysis indicated that the adoption of ESG metrics in executive compensation programs at S&P 500 companies is now a widespread practice, as companies want to signal the importance of ESG priorities and be responsive to investor expectations. In 2021, 73% of S&P 500 companies linked executive compensation to some form of ESG performance, an increase from 66% in 2020. Most companies in the real estate sector tie ESG performance metrics to executive pay. Alliance Advisors reviewed proxy statements of a group of our compensation peers to assess the use of ESG linked metrics within senior management’s executive incentive plans. Of the 21 peers evaluated, the majority include at least one ESG metric within their executive compensation programs, with varying degrees of robustness. The majority of the metrics were qualitative in nature. Based on the above, the Compensation Committee felt comfortable with how the Company uses ESG metrics in executive compensation decisions.
In setting the 2023 compensation elements, the Compensation Committee considered and relied on the above analysis. As result, our peer group composition for our 2023 compensation remained unchanged from that disclosed in 2022 and includes the companies shown in the table below:

In January 2024, we engaged FPC to analyze the competitiveness of the Company’s executive compensation practices in a benchmarking study. Its analysis focused on the magnitude of pay as well as the structural design of the program. The key takeaways and findings for this study informed the Compensation Committee in setting the 2024 compensation elements and levels for the NEOs.

Compensation Discussion and Analysis
Advisory Vote on Executive Compensation
The advisory vote by shareholders on executive compensation plays a role in our executive compensation decision-making process.
The Compensation Committee considered the results of the advisory vote by shareholders on executive compensation, or the “say-on-pay” proposal, presented to shareholders at our 2023 annual meeting when evaluating our executive compensation program. Last year’s say-on-pay proposal received strong shareholder support, with 84% of the shares voted approving the 2022 executive compensation.
The Compensation Committee made no direct changes to the Company’s executive compensation program as a result of the say-on-pay vote and our executive compensation program for the year ended December 31, 2023 continued to focus on the factors described below.
The chart below shows our say-on-pay results over the last three years:

ADDITIONAL EXECUTIVE COMPENSATION POLICIES AND PRACTICES
Risks Arising from Compensation Policies and Practices
Our senior management has assessed the enterprise-wide risks facing us and has implemented processes and procedures to mitigate such risks. In connection with such ERM processes, our compensation programs were assessed, including program features that could potentially encourage excessive or imprudent risk taking and the specific aspects of our compensation policies and procedures which mitigate some of the material risks that might otherwise arise from such policies and procedures. Following this review, our management, Compensation Committee and Board affirmatively determined that there were no risks arising from the compensation policies and practices that are reasonably likely to have a material adverse effect on us.
Anti-Hedging Policy
We have adopted an Anti-Hedging Policy under which our directors and executive officers who are subject to reporting requirements under Section 16 of the Exchange Act are prohibited from trading in any interest relating to the future price of the Company’s securities, such as a put, call or short sale.
Pledging Guidelines
We have adopted pledging guidelines under which our directors and executive officers are prohibited from pledging any Company securities as collateral for indebtedness unless the NCG Committee has first reviewed and approved the terms of the pledge.
Insider Trading Policy
We have adopted an Insider Trading Policy under which all directors, officers, employees and affiliates of the Company are prohibited from purchasing, selling, or providing such information or recommending a transaction involving the Company's securities when such individual(s) are aware of material nonpublic information of the Company and make a trade on the basis of such information.
Executive Stock Ownership Guidelines
In an effort to align the interests of our management with those of our shareholders, we have adopted a policy under which our executive officers who are subject to reporting requirements under Section 16 of the Exchange Act are subject to equity ownership guidelines. Under these guidelines, each executive officer is required to own shares of our stock with a value equal to a multiple of his or her annual base salary as follows:
PositionMultipleAnnual Base Measure
Chairman and CEO6xBase salary
President and other executive officers4xBase salary
Covered individuals are required to achieve compliance with these guidelines by five years from the later of the date of:
November 2, 2021, which was the date these guidelines were last amended;
promotion to the covered position; or
start of employment with the Company.
Until he or she complies with the guidelines, or if he or she fails to comply due to a reduction in stock price, each covered individual must retain at least 50% of all shares of restricted stock as they vest (not including any newly vested shares sold or withheld to pay applicable taxes).
As of March 18, 2024, each of our NEOs satisfied the requirements of these stock ownership guidelines.
2024 Proxy Statement

Compensation Discussion and Analysis
Executive Compensation Recovery (Clawback) Policy
We have adopted an Executive Compensation Recovery (Clawback) Policy which covers each of the NEOs and other executive officers. Under this policy, in the event of an accounting restatement of the Company’s financial statements due to the Company’s material noncompliance with any financial reporting requirement under U.S. securities laws, the Company shall seek to promptly recover from any covered executive officer the amount of incentive-based compensation received by such executive officer in excess of the amount of incentive-based compensation that would have been received by such executive officer if the calculation was determined based on the accounting restatement. Incentive-based compensation received by a covered executive during the three completed fiscal years immediately preceding the restatement date is subject to potential clawback.
Tax and Accounting Implications
Deductibility of Executive Compensation
Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) limits the deductibility on our tax return of compensation over $1.0 million to any of our NEOs.
We believe that, because we qualify as a REIT under the Code and therefore are not subject to federal income taxes on our income to the extent distributed, the payment of compensation that does not satisfy the requirements of Section 162(m) has not and will not generally affect our net income. However, to the extent that compensation does not qualify for deduction under Section 162(m), a larger portion of shareholder distributions may be subject to federal income taxation as dividend income rather than return of capital.
We do not believe that Section 162(m) has materially affected or will materially affect the taxability of shareholder distributions, although no assurance can be given in this regard due to the variety of factors that affect the tax position of each shareholder.
For these reasons, Section 162(m) is not a significant factor in the Compensation Committee’s compensation policy and practices. In 2023, we made payments of $13,400,315 to Mr. Shiffman, $1,096,539 to Mr. Castro-Caratini, $909,755 to Mr. Thelen, $645,160 to Mr. Farrugia, and $775,559 to Aaron Weiss that were subject to Section 162(m).
409A Considerations
We have also taken into consideration Section 409A of the Code in the design and implementation of our compensation programs. If an executive is entitled to nonqualified deferred compensation benefits that are subject to Section 409A, and such benefits do not comply with Section 409A, then the benefits are taxable in the first year they are not subject to a substantial risk of forfeiture. In such a case, the executive is subject to regular federal income tax, interest and an additional federal income tax of 20% of the benefit includible in income.
Option Awards
In response to Item 402(x)(1) of Regulation S-K, the Company does not currently grant new awards of stock options, stock appreciation rights, or similar option-like instruments. Accordingly, the Company has no specific policy or practice on the timing of awards of such options in relation to the disclosure of material nonpublic information by the Company. In the event the Company determines to grant new awards of such options, the Board will evaluate the appropriate steps to take in relation to the foregoing.

CEO PAY RATIO
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee. We consider the pay ratio specified below to be a reasonable estimate, calculated in a manner that is intended to be consistent with the requirements of Item 402(u) of Regulation S-K. Our pay ratio is provided to assist in evaluating our compensation practices and may not be meaningful when compared against other companies as impacts of varying organizational structures on employment bases and their respective compensation practices, as well as the methodology, assumptions and estimates each company uses in determining its median employee, may impact the pay ratios among and within industries.

Sun Communities, Inc.

Executive Compensation Tables
As an owner and self-operator of the majority of our 667 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 to manage most or all of their properties. Rather than outsourcing property management, the Company’s strategy generally involves 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.
For the year ended December 31, 2023, the annual total compensation of the employee who represents our median compensated employee (other than our CEO) was $38,263. The annual total compensation of our CEO, as reported in the Summary Compensation Table above, was $10,946,746. Based on this information, our CEO pay ratio for 2023 was 286:1.
Over the last three years, shareholders have approved our executive compensation program by an average of 90% support of the votes cast. As set forth in the Compensation Discussion and Analysis, we believe our shareholders’ overwhelming support for the Company’s compensation program reflects the strong alignment between our CEO’s pay and performance.
This information is being provided for compliance purposes. Neither the Compensation Committee nor the management of the Company used the pay ratio measure in making compensation decisions.
Determining the Median Employee
Employee Population
We used our employee population data as of October 30, 2023 as the reference date for identifying our median employee. As of this date, we employed approximately 8,500 talented individuals in full-time, part-time, seasonal and temporary positions worldwide, other than our CEO, all considered in determining our median employee.
We included employees if they were employed by the Company or any of its subsidiaries, on October 30, 2023, and classified as full-time, part-time, temporary and seasonal, and foreign employees (where foreign employee population is greater than 5% of total). We excluded active employees that made less than $500.
Methodology for Determining Our Median Employee
To identify the median employee from our considered population, we used base compensation payroll records as of October 30, 2023, after annualization of compensation for applicable part-time and full-time employees. Base compensation does not include every element of compensation, but does reasonably reflect annual compensation for our employee population.
Annual Total Compensation of Median Employee
With respect to the annual total compensation of the median employee, we calculated such employee’s compensation for 2023 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, pursuant to SEC rules, and consistent with the calculation of compensation for our CEO as reported in our 2023 Summary Compensation Table above. As such, we included commissions, bonuses, stock grants, overtime, and employer contributions to our qualified 401(k) retirement plan.
Our considered population can be categorized into the following areas:
Approximately 80.0% of our employees support operations at over 600 communities and marinas as of October 30, 2023, in positions including, but not limited to, office assistants, member services specialists, housekeepers, groundskeepers and dock hands. These employees are primarily paid on an hourly basis. The median annual total compensation for these employees in 2023 was $33,519.
The operational support employees described above are overseen by managers who are led by regional, divisional and senior vice presidents who account for approximately 7.5% of our workforce in the aggregate. The median annual total compensation for these employees in 2023 was $91,367.
Approximately 12.5% of our workforce is comprised of corporate employees located primarily at our main offices. These employees include our executive management team as well as our finance, human resources, marketing and information technology professionals. The median annual total compensation for these employees in 2023 was $73,462.
Annual total compensation for the identified median employee, an office coordinator, calculated on a basis consistent with the Summary Compensation Table above and excluding our CEO, was $38,263 for 2023.
Annual Total Compensation of our CEO
We used the amount reported in the “Total” column of our 2023 Summary Compensation Table included in this Proxy Statement, which includes the value of benefits provided to our CEO under non-discriminatory benefit plans available to all employees during 2023.

Our compensation "actually paid" is heavily influenced by the fair value of equity awards from year to year. As stock price volatility and fluctuations in the stock market impact the valuations of our awards, our resulting compensation “actually paid” to our PEO and our Non-PEO NEOs can be higher or lower (or even negative, as shown for 2022), than the figures disclosed in the summary compensation table. This is particularly true for our PEO, whose equity awards make up approximately 85% of total compensation for 2023 (83% for 2022, 81% for 2021 and 83% for 2020), and therefore have a significant impact on our overall "actually paid" compensation.

Description of the Relationship Between Pay Versus Performance
The graphs below compare the compensation actually paid to our PEO and the average of the compensation actually paid to Non-PEO NEOs, with (i) our cumulative TSR, (ii) the TSR of the Dow Jones U.S. Real Estate Residential Index, (iii) our Net Income, and (iv) our Core FFO, for the years ended December 31, 2020, 2021, 2022 and 2023. TSR amounts reported in the graph assume an initial fixed investment of $100 and that all dividends were reinvested.
Our program is structured to pay for performance, with an annual incentive award that is largely tied to Core FFO Growth, Same Property Combined NOI Growth (of MH, RV and Marina), MH, RV and marina acquisitions, expansions and developments, and ESG initiatives, along with long-term incentives that are primarily performance-based and align with investor interests as performance is solely predicated on our TSR performance versus that of the MSCI U.S. REIT Index with an absolute TSR modifier that caps our payouts if our return is negative. As such, our compensation paid and performance are strongly aligned, as shown in the graphs below:

Core FFO growth(3.4)%FFO is a standard operating performance measure for REITs and is defined by Nareit as GAAP net income (loss), excluding gains (or losses) from sales of certain real estate assets, plus real estate related depreciation and amortization, impairments of certain real estate assets and investments, and after adjustments for nonconsolidated partnerships and joint ventures. Core FFO is a primary operating measure in our publicly-reported earnings results, and is defined as FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business. Refer to Appendix for the reconciliation of Net Income to Core FFO
Same Property combined NOI growth - MH, RV and Marina7.3%NOI is calculated by deducting direct property operating expenses from property operating revenues, thereby providing a measure of the actual operating performance of our properties. Same Properties are primarily those properties that we have owned and operated continuously since January 1, 2022Refer to (1) Appendix for the reconciliation of Net Income to NOI and (2) table below for the breakdown of NOI

CHANGE OF CONTROL
AND SEVERANCE PAYMENTS
Under their employment agreements, we are obligated to make severance and change of control payments to Mr. Shiffman, Mr. Castro-Caratini, Mr. Thelen, Mr. Farrugia and Aaron Weiss under certain circumstances.
If the employment of any such executive is terminated by us without “cause” or by the executive for “good reason” as defined in his employment agreement, he is entitled to any accrued but unpaid salary, incentive compensation and benefits through the effective date of termination. In addition, subject to the execution of a general release and continued compliance with his non-competition and confidentiality covenants, each such executive is entitled to continued payment of his base salary for up to 18 months after termination.
If the applicable executive's employment is terminated due to death or disability, he, or his successors and assigns, is entitled to any accrued but unpaid salary, incentive compensation and benefits through the effective date of termination. In addition, each executive is entitled to a continuation of salary for up to 24 months after death or disability.
If there is a change of control of the Company (as defined in each executive’s employment agreement) and any of the following occurs or is applicable:
we or a successor entity terminate the employment of the applicable executive without “cause” (as defined in his employment agreement) within two years after the date of such change of control;
the applicable executive terminates his employment for “good reason” (as defined in his employment agreement) within two years after the date of such change of control; or
if the form of such change of control transaction is a sale by the Company of all or substantially all of its assets and the Company or its successor does not expressly assume the employment agreement of the applicable executive
then we are obligated to pay the applicable executive, an amount equal to 2.99 times his then current base salary (less amounts paid between the change of control event and the triggering event), and to continue to provide him health and insurance benefits for up to one year. In addition, in the case of any such triggering event, all stock options or other stock-based compensation awarded to each NEO will become fully vested and immediately exercisable and any stock options may be exercised by him at any time within one year after the triggering event.
Under any of the foregoing events of termination or a change of control, all stock options and other stock-based compensation awarded to the applicable executive shall become fully vested and immediately exercisable.

SUMMARY
What Am I Voting On?
The third proposal to be considered at the Annual Meeting will be the ratification of the selection of Grant Thornton LLP ("Grant Thornton") as our independent registered public accounting firm. The Audit Committee has selected and appointed Grant Thornton as our independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2024. Grant Thornton has audited our consolidated financial statements since 2003. Although ratification by shareholders is not required by law or by our bylaws, the Audit Committee believes that submission of its selection to shareholders is a matter of good corporate governance. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if the Audit Committee believes that such a change would be in the best interests of the Company and our shareholders. If our shareholders do not ratify the appointment of Grant Thornton, the Audit Committee will take that fact into consideration, together with such other factors it deems relevant, in determining its next selection of independent auditors.
It is anticipated that a representative of Grant Thornton will attend the Annual Meeting, will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.
Vote Required
A majority of the votes cast at the Annual Meeting is required to ratify the selection of Grant Thornton. Abstentions will not count as votes cast for this proposal and do not represent votes cast for or against the ratification of the selection of Grant Thornton. In the absence of your voting instructions, your broker or nominee may vote your shares for this proposal in its discretion.
https://cdn.kscope.io/00302446c1499c06817e14eff2e9822a-Image_206.jpg 
The Board unanimously recommends that you vote “FOR” the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2024.

Proposal No. 3 – Ratification of Selection of Grant Thornton LLP
ENGAGEMENT OF GRANT THORNTON LLP
The Audit Committee is directly responsible for the appointment, compensation, retention, and oversight of the independent accountants. The Audit Committee has appointed Grant Thornton as our independent accountants to audit the consolidated financial statements of the Company for the year ending December 31, 2024. Grant Thornton has audited our consolidated financial statements since 2003, served as the Company’s independent accountants for the year ended December 31, 2023, and reported on the Company’s consolidated financial statements for the year.
The Audit Committee annually reviews Grant Thornton’s independence and performance in determining whether to retain Grant Thornton or engage another independent registered public accounting firm as our independent accountants. As part of that annual review, the Audit Committee considers, among other things, the following:
the quality and efficiency of the current and historical services provided to us by Grant Thornton;
Grant Thornton’s capability and expertise in handling the breadth and complexity of our company’s operations;
the quality and candor of Grant Thornton’s communications with the Audit Committee;
Grant Thornton’s qualifications and performance;
Grant Thornton’s independence from us;
the appropriateness of Grant Thornton’s fees; and
Grant Thornton’s tenure as our Company’s independent accountants, including the benefits of having a long-tenured auditor.
FEES PAID TO INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Auditor Fees Policy
The Audit Committee has a policy on the pre-approval of audit and non-audit services to be provided by our independent auditors. The policy requires that all services provided by the independent auditors to us, including audit services, audit-related services, tax services and other services, must be pre-approved by the Audit Committee. In some cases, pre-approval is provided by the full Audit Committee for up to a year, and relates to a particular category or group of services and is subject to a particular budget. In other cases, specific pre-approval is required. All of the services provided by our independent auditor in 2023 and 2022 including services related to audit, audit-related fees, tax fees and all other fees described below, were approved by the Audit Committee under its pre-approval policies.
Auditor Fees
Aggregate fees for professional services rendered by Grant Thornton, our independent auditors, for the years ended December 31, 2023 and 2022 were as follows:
CategoryDecember 31, 2023December 31, 2022
Audit Fees: For professional services rendered for the audit of our financial statements, the audit of internal controls relating to Section 404 of the Sarbanes-Oxley Act, the reviews of quarterly financial statements, consents and comfort letters$3,296,100 $1,960,223

The Board maintains an Audit Committee comprised of four directors. The directors who serve on the Audit Committee are all “independent” for purposes of the NYSE listing standards. The Audit Committee held four formal meetings during the year ended December 31, 2023.
In accordance with its written charter, the Audit Committee assists the Board with fulfilling its oversight responsibility regarding quality and integrity of our accounting, auditing and financial reporting practices. In discharging its oversight responsibilities regarding the audit process, the Audit Committee:
reviewed and discussed the audited financial statements with management and Grant Thornton, our independent auditors, for the fiscal year ended December 31, 2023;
discussed with the independent auditors those matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC; and
received and reviewed the written disclosures and the letter from the independent auditors required by the Independence Standards Board’s Standard No. 1 (Independence Discussions with Audit Committees), and discussed with the independent auditors any relationships that may impact their objectivity and independence.
Based upon the review and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, be filed with the SEC.
The Audit Committee has considered and determined that the level of fees of Grant Thornton for provision of services other than the audit services is compatible with maintaining the auditor’s independence.

ABOUT THE ANNUAL MEETING
This year our Annual Meeting will be a completely virtual meeting. There will be no physical meeting location. The meeting will only be conducted via a live webcast.
What is the Purpose of the Annual Meeting?
At the Annual Meeting, shareholders will vote on the following proposals:
Proposal No. 1 — Elect ten directors to serve until our 2025 Annual Meeting of Shareholders and until their successors shall have been duly elected and qualified, or their earlier resignation or removal;
Proposal No. 2 — Non-binding advisory vote on executive compensation; and
Proposal No. 3 — Ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2024.
In addition, shareholders shall consider any other business properly brought before the Annual Meeting.
We have sent these proxy materials to you because our Board is requesting that you allow your shares of our common stock to be represented at the Annual Meeting by the proxies named in the enclosed proxy card. This Proxy Statement contains information that we are required to provide you under the rules of the SEC and that is designed to assist you in voting your shares of common stock.
Why are you holding a virtual Annual Meeting?
The Annual Meeting will be held in a virtual meeting format only. We have designed our virtual format to enhance, rather than constrain, shareholder access, participation and communication. Our goal for the Annual Meeting is to enable the largest number of shareholders to participate in the meeting, while providing substantially the same access and possibilities for exchange with the Board and our senior management as an in-person meeting. We believe that this approach represents best practices for virtual shareholder meetings. For example, the virtual format allows shareholders to communicate with us in advance of, and during, the Annual Meeting so they can ask questions of our Board or management. During the live Q&A session of the Annual Meeting, we may answer questions as they come in and address those asked in advance, to the extent relevant to the business of the Annual Meeting, as time permits.
How do I attend and vote shares at the virtual Annual Meeting?
The Annual Meeting will begin at 11:00 a.m. EDT on May 14, 2024. We encourage shareholders to access the meeting prior to the start time. Please allow ample time for check-in, which will begin at 10:45 a.m. EDT. In order to participate in the Annual Meeting live via the Internet, you must log in at www.virtualshareholdermeeting.com/SUI2024 and be sure to enter the 16-digit number found on your proxy card, voting instruction form or notice you previously received. You may vote during the Annual Meeting by following the instructions available on the meeting website during the meeting. You may also attend the meeting and vote online at the meeting if you have obtained a legal proxy from your bank or broker.
On the day of the Annual Meeting, if you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Shareholder Meeting login page.
Even if you plan to attend the live webcast of the Annual Meeting, we encourage you to vote in advance by Internet, telephone or mail so that your vote will be counted even if you later decide not to attend the virtual Annual Meeting. We will provide a physical location for shareholders to attend the meeting via the webcast if requested by a shareholder in writing by contacting the Secretary at Sun Communities, Inc., 27777 Franklin Road, Suite 300, Southfield, MI 48034. Please note that no members of management or the Board will be in attendance at the physical location.

General Information
How can I ask questions during the Annual Meeting?
Questions may be submitted prior to the meeting at www.proxyvote.com or you may submit questions in real time during the meeting using our Annual Meeting Website. Please note that shareholders will need their unique control number which appears on their Notice of Internet Availability, the proxy card (printed in the box and marked by the arrow), and the instructions that accompanied the proxy materials in order to access these sites. Beneficial shareholders who do not have a control number may gain access to the meeting by logging into their broker, brokerage firm, bank, or other nominee’s website and selecting the shareholder communications mailbox to link through to the Annual Meeting. Instructions should also be provided on the voting instruction card provided by your broker, bank, or other nominee.
Questions submitted in accordance with the Rules of Conduct and Procedures (available on the Annual Meeting Website) will be generally addressed in the order received and we limit each shareholder to one question in order to allow us to answer questions from as many shareholders as possible. Answers to any such questions that are not addressed during the meeting will be published following the meeting on www.suninc.com/investor-relations. Questions regarding personal matters, including general economic, political, or product questions, which are not directly related to the business of the Company are not pertinent to meeting matters and therefore will not be answered. If there are matters of individual concern to a shareholder and not of general concern to all shareholders, or if a question posed was not otherwise answered, we provide an opportunity for shareholders to contact us separately after the Annual Meeting through our Investor Relations website www.suninc/investor-relations.
If you are eligible to attend the 2024 annual meeting but cannot submit your question using www.proxyvote.com or the Annual Meeting Website, please contact our Investor Relations Department at (248) 208-2500 for accommodations.
What can I do if I need technical assistance during the Annual Meeting?
If you encounter any difficulties accessing the virtual Annual Meeting webcast, please call the technical support number that will be posted on the Annual Meeting Website log-in page.
Who is Entitled to Vote?
You will be entitled to vote your shares of common stock on the proposals if you held your shares of common stock at the close of business on the Record Date. As of the Record Date, a total of 124,642,332 shares of common stock were outstanding and entitled to vote held by 738 holders of record. Each share of common stock entitles its holder to cast one vote for each matter to be voted upon.
What is Required to Hold the Annual Meeting?
The presence at the Annual Meeting of the holders of a majority of the shares of common stock outstanding and entitled to vote on the Record Date will constitute a quorum permitting business to be conducted at the Annual Meeting. If you have returned valid proxy instructions or you attend the Annual Meeting, your shares of common stock 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 Annual Meeting. If there is not a quorum at the Annual Meeting, the shareholders entitled to vote at the Annual Meeting, whether present in person or represented by proxy, will only have the power to adjourn the Annual Meeting until such time as there is a quorum. The Annual Meeting may be reconvened without notice to the shareholders, other than an announcement at the prior adjournment of the Annual Meeting, within 120 days after the Record Date, and a quorum must be present at such reconvened Annual Meeting.

FOR the non-binding approval of the executive compensation as disclosed in this Proxy Statement; and
FOR the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2024; and

What Vote is Needed to Approve Each Proposal?
The following are the votes needed in order for each proposal to be approved at the Annual Meeting. For all proposals, a quorum must be present at the Annual Meeting.
Proposal No. 1: The affirmative vote by a majority of all the votes cast at the Annual Meeting is necessary for the election of ten directors to serve until our 2025 annual meeting of shareholders, and until their successors shall have been duly elected and qualified, or until their earlier resignation or removal.
Proposal No. 2: The affirmative vote by a majority of all the votes cast at the Annual Meeting is required for the non-binding approval of the executive compensation of our NEOs as disclosed in this Proxy Statement.
Proposal No. 3: The affirmative vote by a majority of all the votes cast at the Annual Meeting is required for the ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm for 2024.
We will treat abstentions as shares that are present and entitled to vote for purposes of determining the presence or absence of a quorum. Abstentions will not be counted as “votes cast.” Abstention will have the same effect as a vote against proposal No 3. Abstentions will have no effect on any of the other proposals. Broker “non-votes,” or proxies from brokers or nominees indicating that such broker or nominee has not received instructions from the beneficial owner or other entity entitled to vote such shares on a particular matter with respect to which such broker or nominee does not have discretionary voting power, will be treated in the same manner as abstentions for purposes of the Annual Meeting. If you are a beneficial owner whose shares of common stock are held of record by a broker, your broker has discretionary voting authority under NYSE rules to vote your shares on Proposal No. 3 even if the broker does not receive voting instructions from you. However, under NYSE rules, your broker does not have discretionary authority to vote on any of the other proposals without instructions from you, in which case a broker “non-vote” will occur, and your shares of common stock will not be voted on these matters.
How is My Vote Counted?
If the proxy in the form enclosed is duly executed, dated and returned, and it has not been revoked in accordance with the instructions enclosed, the shares of common stock represented by the proxy will be voted by Gary A. Shiffman and Fernando Castro-Caratini, the Board’s proxy agents for the Annual Meeting, in the manner specified in the proxy. If no specification is made, the common stock will be voted “FOR” the election of the ten nominees for the Board, “FOR” the executive compensation as disclosed in this Proxy Statement, and “FOR” the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2024, and at the discretion of Gary A. Shiffman and Fernando Castro-Caratini, the Board's designated representatives for the Annual Meeting, with respect to such other business as may properly come before the Annual Meeting or any adjournment or postponement of the Annual Meeting. It is not anticipated that any matters other than those set forth in this Proxy Statement will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders. In addition, no shareholder proposals or nominations were received on a timely basis, so no such matters may be brought to a vote at the Annual Meeting.
Who is Soliciting My Proxy?
This solicitation of proxies is made by and on behalf of our Board. Proxies may be solicited by personal interview, telephone, facsimile or email or by our directors, officers and employees. Arrangements may also be made with brokerage houses or other custodians, nominees and fiduciaries to forward solicitation material to the beneficial owners of common stock held of record by such persons, and we may reimburse them for reasonable out-of-pocket expenses incurred in forwarding the material.
We have engaged Alliance Advisors LLC as proxy solicitors, and we anticipate fees and expenses will not exceed $12,500. The costs of all proxy solicitation will be borne by us. Alliance Advisors LLC will assist us with voting research, investor outreach and securing votes.
Our principal executive offices are located at 27777 Franklin Road, Suite 300, Southfield, Michigan 48034.

Investors and analysts following the real estate industry use non-GAAP supplemental performance measures, including net operating income ("NOI"), earnings before interest, tax, depreciation and amortization ("EBITDA") and funds from operations ("FFO") to assess REITs. The Company believes that NOI, EBITDA and FFO are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, NOI, EBITDA and FFO are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations used to measure financial position, performance and value. NOI provides a measure of rental operations that does not factor in depreciation, amortization, and non-property specific expenses such as general and administrative expenses. EBITDA provides a further measure to evaluate ability to incur and service debt; EBITDA also provides further measures to evaluate the Company's ability to fund dividends and other cash needs. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets.
NOI
Total Portfolio NOI - The Company calculates NOI by subtracting property operating expenses and real estate taxes from operating property revenues. NOI is a non-GAAP financial measure that the Company believes is helpful to investors as a supplemental measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. The Company uses NOI as a key measure when evaluating performance and growth of particular properties and / or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense and non-property specific expenses such as general and administrative expenses, all of which are significant costs. Therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall. The Company believes that NOI provides enhanced comparability for investor evaluation of properties performance and growth over time.
The Company believes that GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of the Company's financial performance or GAAP cash flow from operating activities as a measure of the Company's liquidity; nor is it indicative of funds available for the Company's cash needs, including its ability to make cash distributions. Because of the inclusion of items such as interest, depreciation and amortization, the use of GAAP net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level.
Same Property NOI - This is a key management tool used when evaluating performance and growth of the Company's Same Property portfolio. The Company believes that Same Property NOI is helpful to investors as a supplemental comparative performance measure of the income generated from the Same property portfolio from one period to the next. Same Property NOI does not include the revenues and expenses related to home sales, service, retail, dining and entertainment activities at the properties.
EBITDA
EBITDAre - Nareit refers to EBITDA as “EBITDAre” and calculates it as GAAP net income (loss), plus interest expense, plus income tax expense, plus depreciation and amortization, plus or minus losses or gains on the disposition of depreciated property (including losses or gains on change of control), plus impairment write-downs of depreciated property and of investments in nonconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, and adjustments to reflect the entity’s share of EBITDAre of nonconsolidated affiliates. EBITDAre is a non-GAAP financial measure that the Company uses to evaluate its ability to incur and service debt, fund dividends and other cash needs and cover fixed costs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs.

2024 Proxy Statement
115

Appendix – Non-GAAP Financial Measures
Recurring EBITDA - The Company also uses EBITDAre excluding certain gain and loss items that management considers unrelated to measurement of the Company’s performance on a basis that is independent of capital structure (“Recurring EBITDA”). The Company believes that GAAP net income (loss) is the most directly comparable measure to EBITDAre. EBITDAre is not intended to be used as a measure of the Company’s cash generated by operations or its dividend-paying capacity, and should therefore not replace GAAP net income (loss) as an indication of the Company’s financial performance or GAAP cash flow from operating, investing and financing activities as measures of liquidity.
FFO
FFO - Nareit defines FFO as GAAP net income (loss), excluding gains (or losses) from sales of certain real estate assets, plus real estate related depreciation and amortization, impairments of certain real estate assets and investments, and after adjustments for nonconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of the Company’s operating performance. By excluding gains and losses related to sales of previously depreciated operating real estate assets, real estate related impairment and real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period-over-period, reflects the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not readily apparent from GAAP net income (loss). Management believes the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful.
Core FFO
Core FFO - In addition to FFO, the Company uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of the Company's core business (“Core FFO”). The Company believes that Core FFO provides enhanced comparability for investor evaluations of period-over-period results.
The Company believes that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a financial performance measure or GAAP cash flow from operating activities as a measure of the Company's liquidity. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Furthermore, FFO is not intended as a measure of a REIT’s ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO is calculated in accordance with the Company’s interpretation of standards established by Nareit, which may not be comparable to FFO reported by other REITs that interpret the Nareit definition differently.
