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.



05_photo_Sun Communities 2025_T1_letter.jpg
Dear Fellow Shareholders,
Throughout 2024 Sun aimed to simplify our business, focus on our portfolio’s durable income streams, and improve our balance sheet. We made notable progress throughout the year and added to our achievements with the February 2025 announcement of the agreement to sell Safe Harbor Marinas to Blackstone Infrastructure. Safe Harbor was an excellent investment for Sun and the sale at this time allows us to achieve several of our strategic objectives, most notably refocusing on our core MH and RV segments and meaningfully improving our leverage profile, while realizing a very attractive return. Sun returns to being a pure-play owner and operator of best-in-class manufactured housing and RV communities, supported by a strong balance sheet.
2024 Results
In 2024, Sun once again delivered strong results in our Manufactured Housing segment, demonstrating the ongoing demand for attainable housing. On the RV side we have remained focused on continuing to increase the contribution from real property and annual income streams. For the full year, approximately 70% of our revenue producing site gains came from RV transient to annual conversions. We also worked to better align expenses with their respective revenue streams. In the UK, positive sales momentum continued, with strong unit sales which in turn drive real property income.
A key priority for Sun has been focusing on our core portfolio through the selective disposition of non-strategic assets and reduction of capital expenditures. For 2024 and through our fourth quarter earnings release on February 26, 2025, we completed total dispositions of approximately $570 million including $180 million in the fourth quarter and year to date 2025. We also reduced non-recurring capital expenditures, which decreased nearly 50%, from 2023 to 2024.
Governance and CEO Retirement
We further enhanced our governance through board refreshment. Over the last 12 months, we added two new members to our board of directors, had two longer serving Board members step down, and announced additional planned refreshment. In March 2025, we announced the nomination of Mark A. Denien as an independent director candidate for election at the upcoming annual meeting of shareholders. Additionally, in November 2024, Gary announced his intention to retire in 2025. The board search committee continues its comprehensive search process and we will provide an update at the appropriate time.
In Closing
We are confident in the favorable dynamics and durable income streams of our core businesses and are encouraged with our outlook. Furthermore, we continue to implement our operating initiatives which focus on maximizing top-line revenue growth to drive bottom-line operational results. We have a clear strategic direction, focused on realizing the full potential of our portfolio and platform.
Thank you for your continued support.
Sincerely,

On February 24, 2025, we entered into a purchase agreement to sell Safe Harbor for an aggregate purchase price of approximately $5.65 billion, subject to certain adjustments (the "Safe Harbor Sale"). While the Safe Harbor Sale is anticipated to close in the second quarter of 2025, it may not be completed on the anticipated timeline, or at all. The closing of the Safe Harbor Sale is subject to the satisfaction or waiver of certain customary conditions to closing. The transfer of subsidiaries owning approximately 25 of Safe Harbor's properties (the "Delayed Consent Subsidiaries") is further subject to the receipt of certain third-party consents and the Delayed Consent Subsidiaries therefore may be transferred in one or more subsequent closings, and is subject to certain conditions to closing.

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 FFO per Share, Core FFO per Share, Recurring EBITDA, North America and UK 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 C for more detail on these terms and reconciliations of these non-GAAP financial measures to GAAP measures.
2024 REVIEW
In 2024, we continued a strategic initiative to simplify our business model and capital structure in order to streamline the organization and focus on our fundamental strengths. During the year ended December 31, 2024, we sold 25 operating properties and three development properties for a total gross sales price of $476.8 million and commenced an internal restructuring plan. The property dispositions have strengthened our financial position by enabling us to reduce debt while also exiting non-core markets. The restructuring plan has enabled us to identify actionable expense savings in 2025. While reshaping our portfolio and operations for future growth, we also continued to generate strong combined North America and UK Same Property NOI growth of 4.3% in 2024, including growth of 6.7% for the MH segment, 5.4% for the Marina segment and 9.0% for the UK segment. Our 2024 Core FFO per Share was $6.81 and, based on 10-year TSRs, our common stock outperformed many of the leading real estate and market indices. We believe that our simplification initiative will position our Company to focus on our best in class portfolio and deliver reliable earnings growth going forward.

The amendment to our 2015 Equity Incentive Plan extends the term of the plan to December 31, 2035. If not extended, the 2015 Equity Incentive Plan will expire on July 20, 2025.

The Board believes that the 2015 Equity Incentive Plan serves a critical role in attracting and motivating valuable employees that will be essential to the future success of the Company.

Proxy Summary
EXECUTIVE COMPENSATION HIGHLIGHTS
Philosophy and Objectives
Our executive officer compensation program supports our commitment to provide superior shareholder value. This program is designed to:
Attract, retain and reward executives who have the motivation, experience and skills necessary to lead us effectively and encourage them to make career commitments to us;
Base executive compensation levels on our overall financial and operational performance and the individual contribution of an executive officer to our success;
Create a link between the performance of our stock and executive compensation; and
Position executive compensation levels to be competitive with other similarly situated public companies, especially those in the real estate industry.
Elements of Compensation
The elements of 2024 executive compensation, as well as the compensation mix for our CEO, is shown below:

The above time restricted stock award, representing 13.5% of total executive compensation, is calculated based on the grant date fair value in accordance with FASB ASC Topic 718.
The compensation mix for our CEO in the table above reflects a smaller percentage of equity pay compared to historical practice, as the Compensation Committee determined to award Mr. Shiffman only 5,000 shares in 2024 in light of the Company's performance. The 2024 award represented a significant decline compared to Mr. Shiffman's average award of 81,667 shares per year over the prior three years. In 2023, Mr. Shiffman's compensation mix included 91.8% of compensation in the form of equity, which is a more representative reflection of historical practice related to compensation mix for our CEO.

Proxy Summary
Compensation Best Practices
What We DoWhat We Don't Do
Pay for Performance: Majority of pay is performance based and not guaranteed.
Clawback Policy: We maintain an Executive Compensation Recovery (Clawback) Policy that requires recovery of erroneously awarded compensation in the event of an accounting restatement due to material non-compliance with any financial reporting requirement under federal securities laws.
Stock Ownership Guidelines: Executives must comply with stock ownership requirements (6x multiple of salary for Chairman and CEO; 4x multiple of salary for other executives).
Annual Compensation Risk Review: Annually assess risk in compensation programs.
Challenging Performance Objectives: Set challenging performance objectives for annual incentives.
Double Trigger Change of Control Agreements: An executive is entitled to severance only if, within a specified period following a change of control, he or she is terminated without cause or resigns for good reason, or the successor company does not expressly assume his or her employment agreement.
Use of Independent Consultant: The Compensation Committee has retained an independent compensation consultant that performs no other consulting services for the Company and has no conflicts of interest.
No Hedging: Directors and executive officers are prohibited from hedging their ownership of the Company's stock.
Pledging: Directors and executive officers are prohibited from pledging any of the Company’s securities as collateral for indebtedness unless the NCG Committee has first reviewed and approved the terms of the pledge.
No Excise Tax Gross Ups: The Company will not enter into any new agreements, or materially amend any existing employment agreements, with its executives that provide excise tax gross-ups in the event of a change of control of the Company.
Additional details about each of our executive officers can be found on pages 19-23 and 92-94.

SUMMARY
What Am I Voting On?
Nine 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. All of the nominees were elected to the Board at the 2024 annual meeting. Each of the directors has served continuously from the date of his or her election or appointment to the present time.
Stephanie W. Bergeron will not stand for re-election, as Ms. Bergeron will retire from the Board on the date of the Annual Meeting, as a result of the Board's focus on refreshment. Furthermore, Clunet R. Lewis informed the Board that he intends to retire from the Board no later than the Company's 2026 annual meeting of shareholders. Ms. Bergeron and Mr. Lewis expect to actively serve on the Board until their respective retirement dates.
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 2026 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 nine 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 nine nominees.

BOARD COMPOSITION AND REFRESHMENT
Thoughtful consideration is continuously given to the composition of our Board in order to maintain an appropriate mix of qualifications, experience and skills, introduce fresh perspectives, and broaden and diversify the view and expertise represented on the Board. As a result of our focus on refreshment, the Company appointed two new directors to the Board in early 2024, Jerome W. Ehlinger and Craig A. Leupold, each of whom was subsequently re-elected to continue serving on the Board at the 2024 annual meeting. Furthermore, Ronald A. Klein and Arthur A. Weiss, two of the longer-tenured directors, retired from the Board during 2024. Additionally, Stephanie W. Bergeron informed the Board that she will not stand for re-election at the Annual Meeting, and Clunet R. Lewis informed the Board that he intends to retire from the Board no later than the Company's 2026 annual meeting of shareholders. Ms. Bergeron and Mr. Lewis expect to actively serve on the Board until their respective retirement dates.
The Board has nominated Mark A. Denien, former Executive Vice President and Chief Financial Officer of Duke Realty Corporation, for the seat currently held by Ms. Bergeron. If Mr. Denien is appointed to the Board, it would mark the Company’s third new independent director appointment since the beginning of 2024. Mr. Denien brings over 30 years of experience in real estate transactions, capital markets, strategy development, regulatory compliance, risk management, and acquisitions. If elected at the Annual Meeting, the Board intends to appoint Mr. Denien to serve as a member of the Audit Committee. The Board believes that Mr. Denien will bring valuable experience, judgment, and talents to the Board.
To further focus on refreshment, there were several changes to committee memberships amongst the current Board members in 2024 to help facilitate new perspectives and viewpoints and the Board expects to make further changes to the committees after the Annual Meeting. See "Committees of the Board" beginning on page 32.

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 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.

Corporate Governance
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.
Board Meetings and Attendance
The Board meets quarterly, or more often as necessary.
The Board met eighteen times during 2024 and took various actions by written consent.
All directors attended at least 75% of the meetings of the Board and each committee on which they served.
While the Board does not have a formal policy, all directors are encouraged to attend annual meetings of shareholders. All of our then-serving Board members attended the 2024 annual meeting.

The Board of Directors attend training sessions on diverse topics on an annual basis, which have included:

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 actively oversee and monitor management of the most significant risks to the Company. 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.

The NCG Committee oversees succession planning for the Board, 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.
In November 2024, Gary A. Shiffman informed the Board of his intention to retire in 2025, following over 40 years of dedicated service to the Company. Accordingly, the Board established a CEO Succession Planning Committee to plan for the orderly transition of the CEO position upon Mr. Shiffman's retirement in 2025. The CEO Succession Planning Committee is led by Co-Chairs and current Board members Jeff T. Blau and Tonya Allen.
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.
The Compensation Committee considers succession planning input from the Board and the NCG Committee when determining compensation packages for the Board and NEOs.

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 standard to ensure the consistent application of security principles, policy statements, and controls. By adhering to this industry standard, we manage and mitigate material risks from threats to our systems and data through the following actions:
Partnering with reputable, recognized security firms
Conducting regular internal and external audits and risk assessments
Providing ongoing employee security awareness training
Conducting tabletop exercises
Running anti-phishing campaigns and simulated phishing exercises
Deploying tools for continuous vulnerability monitoring
Performing penetration testing and continuous system monitoring activities
Conducting recovery simulations for core systems and data centers
Our comprehensive policies and procedures address critical areas including:
Vulnerability management
Business continuity planning
Encryption of sensitive data
Backup and recovery
Physical security
User access controls
Vendor risk management
Teleworking protocols
Mobile device management
Comprehensive system monitoring
These initiatives collectively reinforce our commitment to safeguarding information and ensuring the resilience of our security infrastructure.
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.

Corporate Governance
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 Chief Information Officer and the Director of Information Security are directly responsible for managing cyber risk on a daily basis. The Chief Information Officer reports to the Chief Administrative Officer, who oversees the Company’s overall information technology strategy and governance. Executive oversight, spearheaded by the Chief Administrative Officer, is designed to create strategic alignment across the organization.
The Information Security Management Committee (ISMC) and Enterprise Risk Management Committee (ERM) 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.
Board’s Role in Oversight of Human Capital Management and Culture
The Board is actively engaged in overseeing the Company’s people and culture strategy. The NCG Committee reviews and reports back to the Board on a broad range of human capital management topics, including corporate culture, diversity, inclusion, talent acquisition, retention, employee satisfaction, engagement and succession planning. We report on human capital matters at each regularly scheduled NCG Committee meeting and periodically throughout the year, and annually at a regularly scheduled Board meeting.
Board’s Role in Oversight of Sustainability
As part of the Company's corporate governance, our Board is responsible to our stakeholders for the oversight of the Company. The NCG Committee oversees the implementation of new initiatives, plus the refinement of our Environment, Social and Governance-related reporting and materials. We believe in maintaining transparency and strong governance based on the highest ethical standards.
Committees of the Board
Each of the following Committees of the Board plays an active role in oversight of our sustainability strategy:
NCG Committee
Reviews the Environment, Social and Governance strategy, initiatives and policies developed by management, and receives updates on significant Environment, Social and Governance activities
Aligns implementation and reporting across all portfolios
Compensation Committee
Designs executive compensation to take into consideration the achievement of sustainability goals

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 Chief Executive Officer. 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. Gary A. Shiffman currently serves as our Chairman of the Board and Chief Executive Officer. The Board believes that combining the Chairman and Chief Executive Officer 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 the MH and RV 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, currently is in the best position, as Chairman and Chief Executive Officer, 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 at this time because it allows one person to speak for, and lead, the Company and the Board, and that splitting the roles of Chairman and Chief Executive Officer may cause the Company’s leadership to be less effective.
On November 5, 2024, Mr. Shiffman informed the Board of his intent to retire as CEO by no later than December 31, 2025. Upon Mr. Shiffman’s retirement as CEO, the Board intends to separate the Chairman and CEO roles and will determine which director will serve as Chairman of the Board.
Independence of Non-Employee Directors
The Board 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, 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 2024, 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.

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 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.

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.
The current policy was adopted and approved in March 2022. All related party transactions disclosed below were approved by the NCG Committee, which determined that each such transaction was in the best interests of the Company and included pricing and other terms that are fair to the Company.

OVERVIEW
Gary A. Shiffman, who is our Chairman 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 2024, the Compensation Committee, as part of its review of director compensation, made no change to the directors' cash fee structure or the committee fees. For 2025, all Board and committee fees have been reduced by 20% from 2024 amounts. 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, 2024, 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, 2024, the value of average company stock ownership by the Company’s non-employee directors was 24 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 2019 to 2024 the total director compensation as a percentage of the Company’s total market capitalization has increased by 40%. As a result, we have reduced all Board and committee fees in 2025 to better align director compensation expense with the Company's market capitalization.

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 10, 2025, each of our non-employee directors was in compliance with the stock ownership guidelines.

SUMMARY
What Am I Voting On?
The second proposal to be considered at the Annual Meeting will be a non-binding advisory vote on executive compensation. Section 14A of the Exchange Act requires us to allow shareholders an opportunity to cast a non-binding advisory vote on executive compensation as disclosed in this Proxy Statement. 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 2024 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.

Sun Communities, Inc.

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.

The Board unanimously recommends that you vote “FOR” the executive compensation of our NEOs as disclosed in this Proxy Statement.

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 2024, 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 $6.81. Total North America Same Property NOI (MH, RV and Marina) as compared to 2023 grew by 4.1% during 2024, driven by a 4.6% increase in real property revenues and operating expense growth of 5.7%. In addition, UK Same Property NOI grew by 9.0% as compared to 2023. Occupancy gains contributed to our strong operating results; the 3,210 Revenue Producing Sites we added during the year compared to an increase of 3,270 sites during 2023. Same Property blended occupancy for MH and RV was 98.2% at December 31, 2024, up 40 basis points from year-end 2023. Adjusting for expansion sites delivered and leased, Same Property adjusted blended occupancy for MH and RV increased by 160 basis points year over year, to 99.0% at December 31, 2024. In addition, we effectively managed our balance sheet, capital resources and leverage by monetizing non-strategic assets valued at $476.8 million and paying down total debt of $424.5 million. This reduced our Net Debt to Trailing Twelve-Months Recurring EBITDA ratio to 6.0x at December 31, 2024 (from 6.1x at December 31, 2023), and reduced our percentage of floating rate debt to 8.6% at December 31, 2024 (from 16.4% at December 31, 2023).
From 2010 through 2022, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV, Marina and UK properties. With the benefit of our expanded portfolio, beginning in 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. This strategy continued in 2024 as we divested non-strategic assets in conjunction with our intent to simplify our operations and capital structure.
To simplify our business and reduce our exposure to variable rate debt, we made strong progress toward monetizing assets no longer deemed to be strategic. During 2024, we sold 25 properties and three development properties for a total gross sales price of $476.8 million. Net proceeds from the dispositions were used to strengthen our balance sheet by reducing our total debt. We further strengthened our capital structure in 2024 by entering into and settling forward sale agreements with respect to 2,713,571 shares of common stock for total net proceeds of $361.7 million.
During 2024, we announced an internal restructuring plan and a leadership refreshment initiative. The restructuring plan has enabled us to identify actionable expense savings in 2025 of approximately $15 million - $20 million on an annual run rate basis, which we expect will enhance Core FFO per Share growth going forward. To oversee the restructuring and the execution of these initiatives, John B. McLaren returned to the Company full-time as President. Mr. McLaren brings a proven track record from his 22 years of experience with the Company, including 14 years as the former COO. During his time as COO, Mr. McLaren oversaw the acquisition and integration of approximately 350 MH and RV communities and brought a performance driven approach with a focus on bottom-line operational results.
Furthermore, on November 5, 2024, Gary A. Shiffman informed the Board of his intent to retire as CEO by no later than December 31, 2025.
We achieved a 10-year TSR of 168.9% outperforming the MSCI U.S. REIT (“RMS”) and U.S. REIT Residential indices during the same period.

Compensation Discussion and Analysis
Performance Highlights
When determining compensation for the year ended December 31, 2024, 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, Marina, and UK
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, 2023.
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.
G&A growth, net of add-backsGrowth in general and administrative expenses, net of dead deal costs, integration costs related to the new ERP implementation and other non-recurring expenses, compared to the prior year.
Net Debt / TTM Recurring EBITDARatio of the carrying value of debt, plus unamortized premiums, discounts, and deferred financing costs, less unrestricted cash and cash equivalents, compared to Recurring EBITDA for the trailing twelve months.
Sustainability initiatives
Performance is based on implementation and progress towards long-term commitments, including diversity, equity and inclusion goals and long-term carbon reduction goals.
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
Simplification of Operations and Capital Structure
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. In 2024, we continued a strategic initiative to simplify our business model and capital structure in order to streamline the organization and focus on our fundamental strengths in key markets.
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 9,200 transient RV sites, increasing its annual RV sites by nearly 23%.
In 2023 and 2024, we shifted our strategy toward optimizing the value of our existing businesses and simplifying our business model and capital structure. 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. We believe that our simplification initiative will position our Company to focus on our best in class portfolio and deliver reliable earnings growth going forward.
During the last five years, we have acquired properties valued in excess of $6.7 billion as detailed in the table below:

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
7513
Net Debt to Recurring EBITDA
7544
Recurring EBITDA to Interest
7575
(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
2024 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 2024 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, 2024, as 92% of shareholders supported our 2023 executive compensation program. See the Advisory Vote on Executive Compensation section, under the Compensation Processes on page 78 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.
NEO Compensation and Performance Alignment
Introduction
The Company’s compensation program is designed to closely align the interests of our executives with those of our shareholders, emphasizing a strong relationship between pay and performance. This approach is reflected in our compensation program structure, which has remained largely unchanged since 2018 and has been consistently supported by our shareholders. Our compensation program should reward executives for strong performance when exhibited, while payouts should be muted in years when the Company does not meet rigorous levels of performance objectives. Whereas Company executives garnered above target payouts in years when performance was outstanding, the relatively low bonus and performance-based equity payouts in the past couple of years that continued in 2024 reflect a well aligned pay-for-performance construct that accounts for the Company’s subpar performance in recent years.
Total Shareholder Return
In comparison to the two most directly comparable indices, the MSCI U.S. REIT Index (RMS) and the Dow Jones Equity All REIT Index, each of which the Company is a constituent of, our 10-year TSR has performed exceptionally well. 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 compared to the REIT indices over time as evidenced in the chart below.

Consistently High “Say-on-Pay” Support Since 2018 Redesign of Compensation Program
The Company’s executive compensation program has received strong shareholder support, as evidenced by consistently high “Say-on-Pay” support. Since 2018 when the Compensation Committee created the current iteration of our executive compensation program, shareholder support for the program has remained robust, with an average approval rating of 92.7%; in the most recent vote that occurred at our 2024 annual meeting, shareholders voted in a consistent matter in which approximately 92% of shareholder votes were “For” our executive pay program; in light of this continued strong support, the Compensation Committee has maintained a similar program design for this year. This endorsement reflects the alignment between our compensation practices and shareholder preferences.

Large Emphasis on “At-Risk” Pay
A key characteristic of our compensation structure is that it is highly performance-based and “at-risk.” A relatively small portion of total compensation is provided in the form of base salary, with the remainder being "at-risk," meaning that it is either directly linked to the Company's performance and the achievement of specific financial, strategic, and individual goals, or its value is tied to stock price. At target levels, our NEOs have an overall average of 78.4% of their pay “at risk.”

Compensation Discussion and Analysis
Best In Class Design
The equity component of our program is predominantly performance-based – all of the performance portion is tied to relative total shareholder return (“TSR”) performance. Moreover, performance hurdles for equity awards are designed to require outperformance, where target pay will result from 55th percentile performance, further reinforcing our commitment to driving superior long-term results. Our program also incorporates an absolute TSR modifier, which reduces the potential of funding for executives if returns in a given performance period are negative. These best practices have been in place since 2018 and ensure a direct alignment in terms of executive pay and shareholder value performance.

ABSOLUTE TSR MODIFIER
100% of the performance-based portion of the long-term incentive award is based on TSR
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
Base Salaries: No Changes in Three Years
Importantly, the Company has kept executive compensation consistent and stable over the years, which includes not making any changes to base salaries for any of our NEOs who have served continuously in the past three years. This continuity demonstrates our focus on maintaining a compensation structure that prioritizes performance-based incentives while minimizing unnecessary changes, further reinforcing the strength and stability of our pay-for-performance program.

Annual Incentive Award Program: Rigorous Goals and Lowest Cash Payouts in a Decade
In line with our strong pay-for-performance philosophy, 2024 annual incentive awards (paid in 2025) reflect the lowest payouts in a decade, at an overall average of 41% of target. These payouts directly correspond with our financial, operational, and strategic performance exhibited across 2024 and reflects a rigorous framework that demonstrates a commitment to ensuring that executive compensation is closely aligned with performance.

Compensation Discussion and Analysis
Long-Term Incentive Awards: Largest Pay Component and 100% Aligned with Investors; Second Consecutive Year of No Payouts for Market Performance Awards
The largest portion of executive pay is in the form of equity and the majority, or 60%, is tied directly to total shareholder return performance. The two most recently completed performance-based equity award cycles (2021-2023 and 2022-2024) have resulted in no payouts to executives, further reinforcing the alignment of pay-for-performance. Furthermore, the current performance cycles for 2023-2025 and 2024-2026 are also tracking at 0% payouts as of December 31, 2024, however, there is time remaining for each of these awards and the final results may vary. This continued alignment underscores that our NEOs are incentivized to focus on long-term value creation, ensuring their interests remain closely tied to those of our shareholders.
Below we have shown how, for each of the last four fiscal years, all market performance equity has paid out or is tracking to pay out at $0 compared to the grant date fair value of each year and what is included in the Summary Compensation Table.

Chairman and CEO Pay
In order to further demonstrate the alignment of pay and performance for the Company’s Chairman and Chief Executive Officer, the chart below contains a comparison of the amount of pay that is required to be reported in the Summary Compensation Table and the amount of “realized pay.” "Realized pay" for a given year includes base salary, bonus payout, and the fair value of equity awards granted in the year based on performance equity tracking at 0% and time-based shares valued based on the Company's stock price as of December 31, 2024.
Over the most recent three years, the amount of “realized pay” is approximately 49% of the value of pay disclosed in the Summary Compensation Table. Furthermore, the Compensation Committee significantly decreased the value of Mr. Shiffman’s equity grant in 2024, whereby the value of reported pay in the Summary Compensation Table was approximately 80% less than the amount in 2023 and approximately 90% less than the amount reported in 2022. The significant decrease in equity value granted to Mr. Shiffman in 2024 was concluded upon by the Compensation Committee in order to further align pay with the Company's performance.

2024 EXECUTIVE COMPENSATION
For 2024 performance, the compensation mix for our CEO and other NEOs is shown below:
CEO
118
Other NEOs
131
The annual incentive represents the 2024 annual performance incentive paid in 2025 and the long-term incentive award represents awards issued in 2024, valued at the grant date fair value. The compensation mix for our CEO in the table above reflects a smaller percentage of equity pay compared to historical practice, as the Compensation Committee determined to award Mr. Shiffman only 5,000 shares in 2024 in light of the Company's performance. The 2024 award represented a significant decline compared to Mr. Shiffman's average award of 81,667 shares per year over the prior three years. In 2023, Mr. Shiffman's compensation mix included 91.8% of compensation in the form of equity, which is a more representative reflection of historical practice.
2024 Base Salary
Base salary is generally based on factors such as an individual officer’s level of responsibility, prior years’ compensation, comparison to compensation of other officers and compensation provided at competitive companies and companies of similar size.
Along with peer company benchmarking, the Compensation Committee considered the overall growth in the Company’s total capitalization, the number of MH and RV communities, marinas, and UK communities that the Company owns and operates, the number of employees under management and the corresponding expansion of responsibilities for these executive officers when determining their base salaries.
The base salaries of the NEOs for the year ended December 31, 2024, were paid in accordance with their employment agreements.

Compensation Discussion and Analysis
In setting the 2024 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 2024 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.
In setting the 2024 compensation elements, the Compensation Committee considered and relied on the above analysis. As part of its review of the 2024 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.
2024 Annual Incentive Award
This represents the cash incentive awarded for 2024 performance and paid in 2025.
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.
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.
Annual Incentive Award Structure
For 2024, the threshold, target and maximum incentive opportunities for Fernando Castro-Caratini, Bruce D. Thelen, and Aaron Weiss as a percentage of salary were revised from 2023 to better align the incentive opportunity ranges with peers. For Gary A. Shiffman, the incentive opportunity was unchanged from 2023. The table below provides salary and incentive opportunities as the basis for determination of our 2024 annual incentive awards.

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 North America and UK 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 2024, the Company generated Core FFO per Share of $6.81, despite inflationary pressures and higher interest rates. The Company also achieved strong North America and UK Same Property Combined NOI growth of 4.3% due to the compelling fundamentals of constrained supply and resilient demand that underpin the Company’s businesses, bolstered by the operational excellence of the Company's property management teams, partially offset by a decline in our RV segment due to an increase in supplies and repair expense and other expenses.
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 2024 corporate performance goals. From 2010 through 2023, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV, Marina and UK properties. Beginning in 2023, and prioritizing our focus in 2024, 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, operating efficiencies, and simplification of our operations and capital structure. During 2024, and in order to further align leadership with shareholders, the Compensation Committee removed the Developments and Expansions metric from the predefined 2024 executive annual incentive plan for purposes of computing the 2024 cash incentive amount for Messrs. Shiffman, Castro-Caratini, Thelen and Aaron Weiss. Additionally, to further align leadership with the Company's strategic priorities related to expense management and debt reduction, the Compensation Committee added non-recurring G&A expense and the ratio of Net Debt to Trailing Twelve Month Recurring EBITDA as two new metrics for 2024.
Sustainability initiatives continue to be a focus within the Company. Our team continues to enhance our sustainability protocols and reporting and during 2024 accomplished the following:
Established 2022 as the base year for long-term carbon reduction goals;
Generated 17,236 MWh of solar energy on site, a 48% year over year increase;
Completed an assessment of 7 additional key suppliers for environment and social alignment;
Reported over 17,500 volunteer hours by team members;
Participated in two voluntary environment, social and governance benchmarks;
Achieved a B rating with CDP;
Held over 200 investor engagement meetings

Aaron Weiss - Disposition Bonus:
In addition to the 2024 Annual Incentive Award above, Mr. Aaron Weiss participated in a disposition incentive cash bonus plan designed to align with the Company’s strategic disposition program approved by the Board. The disposition program was a key strategic objective that helped to simplify the Company's operations and capital structure and advanced shareholder interests. The program added increased responsibilities to Mr. Aaron Weiss' workload, and the Compensation Committee determined that the disposition bonus was warranted to compensate him for such an important task.
Performance Objectives
The goal of the disposition program was to dispose of a minimum of $200-$300 million of (i) identified non-core MH and RV assets at favorable valuations and (ii) certain undeveloped land parcels acquired for development that no longer met the Company’s return thresholds in the current cost of capital environment.
Performance Achievements
The resulting outcome for 2024 included the following accomplishments:
Sold 10 US MH properties, 13 Canadian RV properties, two UK MH properties, and three land parcels for approximately $476.8 million;
Achieved an approximately 5% blended cap rate on the sale of the operating assets;
Realized approximately $424.5 million in net proceeds used for debt payoff; and
Executed a purchase and sale agreement on the remaining Blue Water joint venture RV assets in December for approximately $92.9 million, and closed in January 2025, furthering the Company’s business simplification objectives.
Mr. Aaron Weiss was entitled to a cash bonus of $600,000, which was paid in January 2025, based on the successful outcomes noted above, far exceeding the Company’s initial expectations for the strategic disposition program. The disposition bonus has been included with the 2024 Annual Incentive Award payout above, for a total annual incentive award of $895,313 for Mr. Aaron Weiss in the Summary Compensation Table.

Compensation Discussion and Analysis
2024 Long-Term Equity Incentive Awards
This represents the equity award for 2023 performance granted in 2024.
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 other 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.

INVESTOR ALIGNMENT
TARGET TO OUTPERFORM
ABSOLUTE TSR MODIFIER
100% of the performance-based portion of the long-term incentive award is based on TSR
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 2023 performance were granted in 2024 and therefore included in 2024 summary compensation disclosure; awards for 2024 performance are granted in 2025 and therefore will be included in the 2025 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).

Compensation Discussion and Analysis
Long-Term Incentive Awards Granted in 2024
In March 2024, the Compensation Committee granted each of Mr. Shiffman, Mr. Castro-Caratini, Mr. Thelen, 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, for the year ended December 31, 2023, we achieved a 10-year TSR of 323.1%, outperforming the MSCI U.S. REIT (RMS), Russell 1000, Dow Jones Equity ALL REIT and S&P 500 indices during the same period. In addition, we achieved a 5-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 RV, and 11.7% for Marina; and the successful execution of our capital recycling strategy and business simplification strategies.

John B. McLaren
On November 6, 2024, we appointed John B. McLaren as our President in part to oversee a comprehensive restructuring effort to more effectively align the Company's cost structure and deliver sustainable earnings growth. Mr. McLaren served as our Strategic Advisor of Residential Communities from January 2023 to November 2024, with duties focused on our UK operations and integrating new MH developments. Pursuant to his appointment as President, Mr. McLaren was granted 50,000 shares of restricted common stock, 20,000 of which will vest in equal annual installments over five years ("time based shares"), and 30,000 of which are subject to performance vesting after three years based on pending market performance criteria ("market based shares"). In accordance with ASC 718, we concluded that the grant date for the time-based shares was November 6, 2024. In contrast, for the market based shares, we concluded that the grant date had not occurred as of December 31, 2024, due to the pending market performance criteria, and the market based shares will be accounted for as a 2025 award and included in Mr. McLaren's 2025 Summary Compensation Table within the 2026 Proxy Statement. The Company will not grant Mr. McLaren any additional restricted stock awards in 2025 or 2026 for his service as President.

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 2024 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 2024 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.

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.
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 2024 annual meeting when evaluating our executive compensation program. Last year’s say-on-pay proposal received strong shareholder support, with 92% of the shares voted approving the 2023 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, 2024 continued to focus on the factors described below.

Compensation Discussion and Analysis
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
The number of shares owned for purposes of meeting the ownership guidelines include the Company's common stock, time based restricted stock, and performance based restricted stock, regardless of the restrictions or the risk of forfeiture. Additionally, shares owned also includes operating partnership units of Sun Communities Operating Limited Partnership.
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).

Compensation Discussion and Analysis
As of March 10, 2025, each of our NEOs was in compliance with the stock ownership guidelines.
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 IRC 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 IRC 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 2024, we made payments of $5,906,749 to Mr. Shiffman, $1,060,243 to Mr. McLaren, $907,132 to Mr. Castro-Caratini, $820,072 to Mr. Thelen, and $666,822 to Aaron Weiss that were subject to Section 162(m).
409A Considerations
We have also taken into consideration Section 409A of the IRC 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 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.
As an owner and self-operator of the majority of our 645 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. While it has retained third-party property managers for a limited number of properties, 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, 2024, the annual total compensation of the employee who represents our median compensated employee (other than our CEO) was $40,086. The annual total compensation of our CEO, as reported in the Summary Compensation Table above, was $1,968,121. Based on this information, our CEO pay ratio for 2024 was 49:1.
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.

Executive Compensation Tables
Determining the Median Employee
Employee Population
We used our employee population data as of October 30, 2024 as the reference date for identifying our median employee. As of this date, we employed approximately 8,550 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, 2024, 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, 2024, 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 2024 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 2024 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% of our employees support operations at over 600 communities and marinas as of October 30, 2024, 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 2024 was $34,869.
The operational support employees described above are overseen by managers who are led by regional, divisional and senior vice presidents who account for approximately 7.2% of our workforce in the aggregate. The median annual total compensation for these employees in 2024 was $89,137.
Approximately 12.8% 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 2024 was $80,861.
Annual total compensation for the identified median employee, a facilities assistant, was $40,086 for 2024.
Annual Total Compensation of our CEO
We used the amount reported in the “Total” column of our 2024 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 2024.

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 through 2024), than the figures disclosed in the summary compensation table. This is particularly true for our PEO, whose equity awards made up approximately 82% of total compensation for 2020 through 2023, 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, 2023 and 2024. 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, Marina, and UK), effective management of general and administrative expense growth and leverage, and sustainability initiatives, and had previously considered acquisitions and expansions and developments. Our program also includes 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$6.81FFO 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 C for the reconciliation of Net Income to Core FFO
Same Property combined NOI growth - MH, RV, Marina, and UK4.3%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, 2023Refer to (1) Appendix C 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. McLaren, Mr. Castro-Caratini, Mr. Thelen 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, 2025. 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.

The Board unanimously recommends that you vote “FOR” the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2025.

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, 2025. Grant Thornton has audited our consolidated financial statements since 2003, served as the Company’s independent accountants for the year ended December 31, 2024, 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 2024 and 2023 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, 2024 and 2023 were as follows:
CategoryDecember 31, 2024December 31, 2023

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 12 formal meetings during the year ended December 31, 2024.
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, 2024;
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, 2024, 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.

SUMMARY
What Am I Voting On?
Introduction
The fourth proposal to be considered at the Annual Meeting will be the approval of the Second Amendment to our 2015 Equity Incentive Plan, as amended (the “2015 Plan”), the form of which is attached to this Proxy Statement as Appendix A. On March 12, 2025, our Board approved and declared the proposed amendment advisable. The proposed amendment is subject to approval by our shareholders.
If the shareholders approve the proposal, the 2015 Plan will be amended to extend the term of the 2015 Plan to December 31, 2035. We are not seeking shareholder approval for an increase in the number of shares available for issuance under the 2015 Plan. We believe, as amended, the 2015 Plan will be an essential element of our competitive compensation package.
The Company operates in a competitive market and its success depends in large part on its ability to attract, retain and reward talented and competent employees. To be able to do so, the Company must offer competitive compensation. The Board believes that the 2015 Plan serves a critical role in attracting and motivating valuable employees that will be essential to the future success of the Company.
Additionally, our Board believes that equity awards align the interests of our employees and other service providers and shareholders by giving our employees and other service providers an ownership stake in the Company, motivate our employees and other service providers to achieve outstanding performance, and provide an effective means of rewarding service providers for their contributions to our success. If shareholders do not approve this proposal, we will be unable to continue our equity incentive program after the 2015 Plan expires on July 20, 2025, which could prevent us from successfully attracting and retaining the highly skilled talent which is essential to our business.
The material features of the 2015 Plan are summarized below. This description is qualified in its entirety by reference to the 2015 Plan, as previously amended, which is attached as Appendix B to this Proxy Statement.
2025 Proxy Statement
101

Proposal No. 4 – Approval of an Amendment to the Company's 2015 Equity Incentive Plan
to Extend the Term of the Plan to December 31, 2035
Summary of the 2015 Plan
The following summary of the 2015 Plan is qualified in its entirety by the specific language of the 2015 Plan.
General. The purpose of the 2015 Plan is to provide certain key employees of the Company with an additional incentive to promote the Company’s financial success and to provide an incentive which the Company may use to induce able persons to enter into or remain in the employment of the Company or a subsidiary of the Company by providing such persons an opportunity to acquire or increase his or her direct proprietary interest in the operations and future of the Company.
Administration; No Repricing. The administrator of the 2015 Plan shall be a committee of three or more directors of the Company with authority to act as provided in Rule 16b−3 promulgated by the SEC under Section 16 of the Exchange Act, as currently in effect and as it may be amended from time to time, and any successor rule, and shall be elected or appointed by the Board of the Directors. Until changed by the Board, the Administrator shall be the Compensation Committee of the Board. Subject to other terms and conditions of the 2015 Plan, the administrator has the full and final authority to, among other things,: (i) designate participants in the 2015 Plan; (ii) determine the options and / or stock-based rights granted to participants; (iii) determine the maximum number of shares of common stock subject to any award; and (iv) establish the terms and conditions of each award. Neither the Board nor the administrator will have the authority to take any of the following actions unless our shareholders have approved such action: (i) reduce the purchase price or exercise price of any outstanding option or stock appreciation right; (ii) subject to certain exceptions related to capital events, cancel any outstanding option or stock appreciation right in exchange for, or replace any outstanding option or stock appreciation right with, cash, another award or any other consideration from us unless specifically provided for by the terms of the 2015 Plan; or (iii) take any other action that is treated as a repricing under generally accepted accounting principles.
Shares Issuable. The maximum number of shares of the common stock that may be issued under the 2015 Plan through awards is 4,750,000 shares of our common stock. The aggregate number of shares actually issued or transferred by the Company upon the exercise of incentive stock options may not exceed 1,000,000 shares. In order that the applicable rules relating to incentive stock options be satisfied, the 2015 Plan provides that the number of shares that may be issued upon the exercise of incentive stock options will not exceed this aggregate share limit. The aggregate number of shares to be issued under the 2015 Plan, will be adjusted in accordance with the terms of the 2015 Plan, in connection with a recapitalization or sale or merger. If an award under the 2015 Plan is forfeited, expires or is settled for cash, then any shares subject to such award may, to the extent of such forfeiture, expiration or cash settlement, be used again for new grants under the 2015 Plan. However, shares of the our common stock tendered or held back upon exercise of an option or settlement of an award to cover the exercise price or tax withholding will not be available for issuance under the 2015 Plan. Awards granted under the 2015 Plan upon the assumption or substitution of outstanding grants from acquired companies shall not reduce the number of shares available for awards unless issued under the 2015 Plan. See "Equity Compensation Plan Information" on page 108 for information about securities previously authorized for issuance under the 2015 Plan.
Participation. Participants in the 2015 Plan shall be officers who are employees of Sun Communities, Inc., or a subsidiary and other employees of the Sun Communities, Inc., or a subsidiary, as the administrator, in its sole discretion, may designate from time to time to receive an award. In addition, the administrator may grant awards under the 2015 Plan to non−employees who, in the judgment of the administrator, render significant services to us, on such terms and conditions as the administrator deems appropriate and consistent with the intent of the 2015 Plan. As of March 10, 2025, approximately 440 employees of the Company and its subsidiaries were eligible to participate in the 2015 Plan.
Minimum Vesting. No award may vest prior to the first anniversary of its due date, subject to certain limited exceptions set forth in the 2015 Plan.
Incentive Stock Options, Non-qualified Stock Options or Performance-Based Options. Under the 2015 Plan, the administrator may grant incentive stock options, non−qualified stock options or performance based options. The exercise price per share of common stock of each option awarded may never be less than the fair market value of such shares on the date the administrator grants an award, provided, however, that in the case of an incentive option granted to a participant who at the time of the grant owns (as defined in Section 424(d) of the IRC) stock in the Company or a subsidiary of the Company or possessing more than ten percent (10%) of the total combined voting power of all classes of stock of any such entity (a “10% Shareholder”), the exercise price must be at least one hundred and ten percent (110%) of the fair market value of our common stock. Subject to terms in the 2015 Plan, no option may be exercisable prior to the first anniversary of the date of grant and no shares of our common stock shall vest under an option prior to the first anniversary of the date of grant. No participant may be granted incentive stock options under the 2015 Plan (or any other of our incentive plans) which would result in stock with an aggregate fair market value (measured on the date of grant) of more than $100,000 first becoming exercisable in any one calendar year, or which would entitle such participant to purchase a number of shares greater than the maximum number permitted by Section 422 of the IRC, as in effect on the date of grant.

Proposal No. 4 – Approval of an Amendment to the Company's 2015 Equity Incentive Plan
to Extend the Term of the Plan to December 31, 2035
Stock Appreciation Rights. Stock appreciation rights may also be issued under the 2015 Plan. Each stock appreciation right will entitle the holder to receive, upon exercise, a payment from us of an amount equal to the incremental value of the stock appreciation rights. The incremental value of a single share of common stock is an amount equal to the remainder derived from subtracting (i) the exercise price for the right established in the award agreement from (ii) the fair market value of a share of common stock on the date of exercise. The terms of any stock appreciation right granted under the 2015 Plan, including the exercise price which may never be less than the fair market value of the underlying share of common stock on the date of grant, will be set forth in an award agreement. Notwithstanding any other provision of the 2015 Plan, any stock appreciation right awarded to an individual who is then subject to Section 16 of the Exchange Act, must comply with the exemption requirements of Rule 16b−3.
Duration. Options and stock appreciation rights shall terminate after the first to occur of the following events: (i) the expiration date of the award as provided in the award agreement; or (ii) termination of the award as provided in Section 8.02 of 2015 Plan; or (iii) in the case of an incentive stock option, the 10th anniversary of the date of grant, unless the participant is a 10% shareholder in which case on the fifth anniversary of the date of grant; or (iv) solely in the case of tandem stock appreciation rights, upon the expiration date of the related option.
Restricted Share Rights. The administrator may grant to any participant an award of a restricted share right entitling such person to receive shares of our common stock (“Restricted Stock”) in such quantity, and on such terms, conditions and restrictions (whether based on performance standards, periods of service or otherwise) as the administrator shall determine on or prior to the date of grant of such award. The administrator shall establish a period of time during which the holder of the restricted share right will not be permitted to sell, assign, transfer, pledge or otherwise encumber or dispose of any shares of Restricted Stock. Subject to Section 8.07 of the 2015 Plan, a restriction period will commence on the date of grant and will not expire prior to the first anniversary of the date of grant.
Transfer Restrictions. Generally, a participant’s rights and interest under the 2015 Plan may not be assigned or transferred other than by will or the laws of descent and distribution. Notwithstanding the foregoing, or any other provision of the 2015 Plan, a participant who holds non−qualified stock options may transfer such options to his or her spouse, lineal ascendants, lineal descendants, or to a duly established trust for the benefit of one or more of these individuals.
Tax Considerations. The grant of options under the 2015 Plan will have no income tax consequences for either us or the participant (unless the option is freely transferable and has a readily ascertainable market value). Upon the exercise of an option to purchase common stock by a participant, the participant will recognize ordinary income and we will be entitled to a deduction in an amount equal to the excess of the fair market value of common stock purchased over the purchase price. Such ordinary income is not subject to withholding of tax by us. The subsequent sale or exchange of common stock acquired pursuant to the exercise of an option would generally give rise to capital gain or loss.
Participants in the 2015 Plan are responsible for the payment of any federal, state or local taxes that we are required by law to withhold with respect to any amount payable and / or shares issuable under a participant’s award. Participants may elect to meet tax withholding obligations by authorizing us to withhold the appropriate number of shares of common stock, the fair market value of which is equal to such amount, or, in the case of the cash payment, the amount of cash, as is determined by us to be sufficient to satisfy applicable tax withholding requirements. Alternatively, participants may elect to direct payment to us in cash of the amount of any taxes required to be withheld with respect to such award.
Amendment; No Repricing. The Board shall have complete power and authority to amend the 2015 Plan at any time and to add any other stock based award or other incentive compensation programs to the 2015 Plan as it deems necessary or appropriate and no approval by our shareholders or by any other person, committee or entity of any kind shall be required to make any amendment; provided, however, that the Board shall not, without the requisite affirmative approval of our shareholders, (i) make any amendment which requires shareholder approval under any applicable law, including Rule 16b−3 or the IRC, or applicable NYSE rules or which, unless approved by the requisite approval of our shareholders, would cause, result in or give rise to “applicable employee remuneration” within the meaning of Section 162(m) of the IRC, with respect to any performance-based option; (ii) reduce the purchase price or exercise price of any outstanding the option or stock appreciation right; (iii) subject to certain exceptions related to capital events, cancel any outstanding option or stock appreciation right in exchange for, or replace any outstanding option or stock appreciation right with, cash, another award or any other consideration from the Company unless specifically provided for by the terms of the 2015 Plan; or (iv) take any other action that is treated as a repricing under generally accepted accounting principles. No termination or amendment of the 2015 Plan may, without the consent of the participant to whom any award shall theretofore have been granted under the 2015 Plan, adversely affect the right of such individual under such award.
Termination. The Board shall have the right and the power to terminate the 2015 Plan at any time. If not terminated earlier, the 2015 Plan will terminate when all shares authorized under the 2015 Plan have been issued. If not terminated earlier, the 2015 Plan will terminate on July 20, 2025; provided that if our shareholders approve this proposal to extend the term of the 2015 Plan, the plan termination date will be extended to December 31, 2035. No award shall be granted under the 2015 Plan after the termination of the 2015 Plan, but the termination of the 2015 Plan shall not have any other effect and any award outstanding at the time of the termination of the 2015 Plan and may be exercised after termination of the 2015 Plan at any time prior to the expiration date of such award to the same extent such award would have been exercisable if the 2015 Plan had not been terminated.

New Plan Benefits. Because awards under the 2015 Plan will be granted in the administrator's discretion, we cannot determine the dollar value or number of shares of our common stock that will in the future be awarded under the 2015 Plan if it is approved by the shareholders at the Annual Meeting.
The amounts included in the following table are grants or awards received by or allocated to each of the persons or groups listed during the fiscal year ended December 31, 2024. The award amounts listed below do not purport to forecast or predict future award amounts under the 2015 Plan to the listed persons or groups and are not indicative of awards that may be granted to such persons, groups, or positions under the 2015 Plan in the event the shareholders approve it at the Annual Meeting.

Vote Required
Adoption and approval of the amendment to the 2015 Plan to extend the term of the 2015 Plan to December 31, 2035, requires approval by the affirmative vote by a majority of all the votes cast in person or by proxy at the Annual Meeting. Abstentions will not be counted as votes cast for this proposal and do not represent votes cast for or against the approval of the amendment to the 2015 Plan. Brokers are not empowered to vote on this 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 this proposal, they will not be counted in determining whether the amendment to the 2015 Plan is approved.
The Board unanimously recommends that you vote “FOR” the approval of the amendment to the 2015 Plan.

These reports are made on documents referred to as Forms 3, 4 and 5. We have reviewed the copies of the reports filed for our directors and executive officers.

What is the Purpose of the Annual Meeting?

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.
What are the Board’s Recommendations?
The Board recommends that you vote using the enclosed proxy card or voting instruction form:
FOR the election of each of the nominees for director;
FOR the non-binding approval of the executive compensation as disclosed in this Proxy Statement;
FOR the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2025; and
FOR the approval of the amendment to our 2015 Equity Incentive Plan to extend the term of the plan to December 31, 2035.

With respect to any other matter that properly comes before the Annual Meeting or any adjournment or postponement thereof, the representatives holding proxies will vote in their own discretion.
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 13, 2025. We encourage shareholders to access the meeting prior to the start time.

General Information
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 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 (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.com/investor-relations.
If you are eligible to attend the 2025 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 127,590,334 shares of common stock were outstanding and entitled to vote held by 686 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. In such case, 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.
How do I Vote?
Your vote is important. Shareholders have a choice of voting over the Internet (either before or during the Annual Meeting), by telephone, or using a traditional proxy card.

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.
2025 Proxy Statement
111

General Information
Proposal No. 1: The affirmative vote by a majority of all the votes cast at the Annual Meeting is necessary for the election of nine directors to serve until our 2026 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 2025.
Proposal No. 4: The affirmative vote by a majority of all the votes cast at the Annual Meeting is required for the approval of the amendment to our 2015 Equity Incentive Plan to extend the term of the plan to December 31, 2035.
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.” 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 nine nominees for the Board, “FOR” the executive compensation as disclosed in this Proxy Statement, “FOR” the ratification of the selection of Grant Thornton as our independent registered public accounting firm for 2025, and “FOR” the approval of the amendment to our 2015 Equity Incentive Plan, 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.
Who is Soliciting My Proxy and What is the Cost?
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 $19,500. 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.
OTHER MATTERS
The Board knows of no other matters to be presented for shareholder action at the Annual Meeting. If any other matters are properly presented at the Annual Meeting for action, it is intended that the persons named in the accompanying proxy and acting thereunder will vote in accordance with their best judgment on such matters.

(e)amend, modify or supplement the terms of any outstanding Award, provided, that, no such amendment, modification or supplement may cause an Award to violate Section 409A of the Code or, without the written consent of the Participant, impair the Participant’s vested rights under an Award Agreement.

4.02    Shares Subject to Terminated Awards. In the event that any Award at any time granted under the Plan is surrendered to the Company, terminated, forfeited, cancelled (other than in connection with the exercise of a tandem Stock Appreciation Right), expires before it has been fully exercised, or an award of Stock Appreciation Rights is exercised for cash, then all shares of Company Common Stock underlying such portion of the Award shall be added to the remaining number of shares of Company Common Stock available for issuance under the Plan. Shares of Company Common Stock tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding shall not be available for issuance under the Plan. Any shares of Company Common Stock issued by the Company pursuant to its assumption or substitution of outstanding grants from acquired companies shall not reduce the number of shares available for Awards under this Plan unless issued under this Plan.
4.03    Adjustments to Reflect Capital Changes.
(a)    Recapitalization. The number and kind of shares subject to outstanding Awards, the Purchase Price or Exercise Price for such shares, and the number and kind of shares available for Awards subsequently granted under the Plan shall be appropriately adjusted to reflect any stock dividend, stock split, combination or exchange of shares, merger, consolidation or other change in capitalization with a similar substantive effect upon the Plan or the Awards granted under the Plan. The Administrator shall have the power to determine the amount of the adjustment to be made in each case.
(b)    Sale or Reorganization. Upon consummation of a Business Combination in which the outstanding shares of Company Common Stock are exchanged for securities, cash or other property of an unrelated corporation or business entity or in the event of a liquidation of the Company (in each case, a “Transaction”), the Administrator may, in its discretion, take any one or more of the following actions as to outstanding Options: (i) provide that such Options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding entity (or an affiliate thereof), (ii) upon written notice to the holders of the Options, provide that all unexercised Options will terminate immediately prior to the consummation of the Transaction unless exercised by the Option holder within a specified period following the date of such notice, and / or (iii) in the event of a Business Combination under the terms of which holders of the Company Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Business Combination, make or provide for a cash payment to the Option holders equal to the difference between (A) the Merger Price times the number of shares of Company Common Stock subject to such outstanding Options (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise prices of all such outstanding Options, in exchange for the termination of such Options. In the event Options will terminate upon consummation of the Transaction as provided in clause (ii) above, each Option holder shall be permitted, within a specified period determined by the Administrator, to exercise all non-vested Options, subject to the consummation of the Transaction.
(c)    Options to Purchase Stock of Acquired CompaniesAfter any reorganization, merger or consolidation in which the Company or a Subsidiary of the Company shall be a surviving corporation, the Administrator may grant substituted Options under the provisions of the Plan, subject to the applicable requirements described in Section 424 of the Code or Section 1.409A-1(b)(5)(v)(D) of the Treasury regulations, replacing old Options granted under a plan of another party to the reorganization, merger or consolidation, where such party’s stock may no longer be issued following such merger or consolidation. The foregoing adjustments and manner of application of the foregoing provisions shall be determined by the Administrator in its sole discretion. Any adjustments may provide for the elimination of any fractional shares which might otherwise have become subject to any Awards.
Article V.
Participation
5.01    Eligible EmployeesParticipants in the Plan shall be the Officers and other employees of the Company or a Subsidiary as the Administrator, in its sole discretion, may designate from time to time to receive an Award. The Administrator’s designation of a Participant in any year shall not require the Administrator to designate such person to receive an Award in any other year. The Administrator shall consider such factors as it deems pertinent in selecting Participants and in determining the type and amount of their respective Awards.
5.02    Special Provisions for Certain Non-EmployeesNotwithstanding any provision contained in this Plan to the contrary, the Administrator may grant Awards under the Plan to non-employees who, in the judgment of the Administrator, render significant services to the Company or a Subsidiary, on such terms and conditions as the Administrator deems appropriate and consistent with the intent of the Plan.

Article VI.
Option Awards
6.01    Power to Grant OptionsThe Administrator may grant to any Participant Options entitling the Participant to purchase shares of Company Common Stock at a price not less than the Fair Market Value of the shares on the Date of Grant, in such quantity and on such terms and subject to such conditions, not inconsistent with the terms of this Plan, as may be established by the Administrator. The Administrator may designate an Option as an Incentive Stock Option, a Non-Qualified Stock Option or a Performance-Based Option. The terms of any Option granted under this Plan shall be set forth in an Award Agreement. Notwithstanding any provision of this Plan to the contrary, (a) any Option awarded to an individual who is then subject to Section 16 of the Exchange Act must comply with the exemption requirements of Rule 16b-3, and (b) subject to Sections 8.03 and 8.07, no Option may be exercisable prior to the first anniversary of the Date of Grant and no shares of Company Common Stock shall vest under an Option prior to the first anniversary of the Date of Grant.
6.02    Purchase Price of Options. The per share Purchase Price of each share of Company Common Stock which may be purchased upon exercise of any Option granted under the Plan may never be less than the Fair Market Value of such shares on the Date of Grant, provided, however, that in the case of an Incentive Stock Option granted to a Participant who at the time of the grant owns (as defined in Section 424(d) of the Code) stock in the Company or a Subsidiary of the Company possessing more than ten percent (10%) of the total combined voting power of all classes of stock of any such entity (a “10% Stockholder”), the Purchase Price must be at least one hundred and ten percent (110%) of the Fair Market Value of the Company Common Stock on the Date of Grant.
6.03    Designation of Incentive Stock OptionsIf the Administrator designates, at the Date of Grant, that the Option is an Incentive Stock Option under Section 422 of the Code, the following additional provisions apply.
(a)    Incentive Stock Option Share LimitationNo Participant may be granted Incentive Stock Options under the Plan (or any other plans of the Company) which would result in stock with an aggregate Fair Market Value (measured on the Date of Grant) of more than $100,000 first becoming exercisable in any one calendar year, or which would entitle such Participant to purchase a number of shares greater than the maximum number permitted by Section 422 of the Code as in effect on the Date of Grant. If the aggregate Fair Market Value (determined at the Date of Grant) of the shares subject to the Option, which first becomes exercisable in any calendar year and during this period exceeds the limitation of this subsection, so much of the Option that does not exceed the applicable dollar limit will be designated as an Incentive Stock Option and the remainder will be designated as a Non-Qualified Stock Option, but in all other aspects the Award Agreement will remain in full force and effect.
(b)    Other Incentive Stock Option TermsWhenever possible, each provision in the Plan and in every Option granted under this Plan which is designated by the Administrator as an Incentive Stock Option will be interpreted in such a manner as to entitle the Option to the tax treatment afforded by Section 422 of the Code. If any provision of this Plan or any Option designated by the Administrator as an Incentive Stock Option does not to comply with requirements necessary to entitle such Option to such tax treatment, then (i) such provision shall be deemed to have contained from the outset such language as is necessary to entitle the Option to the tax treatment afforded under Section 422 of the Code, and (ii) all other provisions of this Plan and the Award Agreement will remain in full force and effect. If any Award Agreement covering an Option designated by the Administrator to be an Incentive Stock Option under this Plan does not explicitly include any terms required to entitle such Incentive Stock Option to the tax treatment afforded by Section 422 of the Code, all such terms shall be deemed implicit in the designation of such Option and the Option shall be deemed to have been granted subject to all such terms.
6.04    Rights as a StockholderThe Participant or any transferee of an Option pursuant to Section 8.02 or Section 11.05 shall have none of the rights of a stockholder with respect to any shares of Company Common Stock covered by an Option until the Participant or transferee is the holder of record of any such shares, and no adjustment shall be made for dividends and cash or other property or distributions or other rights for which the record date is prior to the date the Participant is the holder of record.
Article VII.
Stock Appreciation Rights
7.01    Power to Grant Stock Appreciation RightsThe Administrator is authorized to grant to any Participant a Stock Appreciation Right that entitles the Participant to receive, upon exercise thereof, a payment from the Company, payable as provided in Section 7.04, of an amount equal to the Incremental Value of the Stock Appreciation Rights. The Incremental Value of a single share of Company Common Stock is an amount equal to the remainder derived from subtracting (i) the Exercise Price for the right established in the Award Agreement from (ii) the Fair Market Value of a share of Company Common Stock on the date of exercise. The terms of any Stock Appreciation Right granted under the Plan, including the Exercise Price which may never be less than the Fair Market Value of the underlying share of Company Common Stock on the Date of Grant, will be set forth in an Award Agreement. Notwithstanding any other provision of the Plan, any Stock Appreciation Right awarded to an individual who is then subject to Section 16 of the Exchange Act must comply with the exemption requirements of Rule 16b-3.
2025 Proxy Statement

Appendix B - Sun Communities, Inc. 2015 Equity Incentive Plan
7.02    Tandem Stock Appreciation RightsThe Administrator may grant to any Participant a Stock Appreciation Right covering any share of Company Common Stock which is, at the Date of Grant, also covered by an Option granted to the same Participant, either prior to or simultaneously with the grant to such Participant of the Stock Appreciation Rights, provided: (i) any Option covering any share of Company Common Stock shall expire and not be exercisable upon the exercise of any Stock Appreciation Rights with respect to the same share; (ii) any Stock Appreciation Rights covering any share of Company Common Stock shall not be exercisable upon the exercise of any related Option with respect to the same share; and (iii) an Option and Stock Appreciation Rights covering the same share of Company Common Stock may not be exercised simultaneously.
7.03    Exercise PriceIn the case of a tandem Stock Appreciation Right, the Exercise Price established under any Stock Appreciation Right, as determined by the Administrator and set forth in the Award Agreement, may not be less than the Purchase Price of the related Option. Upon exercise of a tandem Stock Appreciation Right, the number of shares subject to exercise under a related Option will automatically be reduced by the number of shares of Company Common Stock represented by the Option or portion thereof which is surrendered as a result of the exercise of such Stock Appreciation Right.
7.04    Payment of Incremental ValueAny payment which may become due from the Company by reason of Participant’s exercise of a Stock Appreciation Right may be paid to the Participant as determined by the Administrator (i) all in cash, (ii) all in Company Common Stock, or (iii) in any combination of cash and Company Common Stock. In the event that all or a portion of the payment is made in Company Common Stock, the number of shares of the Company Common Stock delivered in satisfaction of such payment will be determined by dividing the amount of the payment by the Fair Market Value on the date of exercise. The Administrator may determine whether payment upon exercise of a Stock Appreciation Right will be made in cash or in stock, or a combination thereof, upon or at any time prior to the exercise of such Stock Appreciation Right. No fractional share of Company Common Stock will be issued to make any payment; if any fractional shares would be issuable, the mix of cash and Company Common Stock payable to the Participant will be adjusted as directed by the Administrator to avoid the issuance of any fractional share.
Article VIII.
Terms of Options and Stock Appreciation Rights
8.01    Duration of Options and Stock Appreciation RightsOptions and Stock Appreciation Rights shall terminate after the first to occur of the following events:
(a)    Expiration Date of the Award as provided in the Award Agreement; or
(b)    Termination of the Award as provided in Section 8.02; or

8.02    Exercise on Death or Separation from Service.
(a)    Unless otherwise provided in the Award Agreement, in the event of the death, disability or retirement of a Participant while an employee of the Company or a Subsidiary of the Company, the right to exercise all unexpired Awards shall be accelerated and shall vest as of the date of death, disability or retirement (as applicable), and, except as provided in Section 8.02(c) below, the Participant’s Awards may be exercised by the Participant or his Beneficiary at any time within one year after the date of the Participant’s death, disability or retirement, as applicable.
(b)    Unless otherwise provided in the Award Agreement, in the event of Participant’s Separation from Service at any time for any reason other than death, disability, retirement or for Cause, an Award may be exercised, but only to the extent it was otherwise exercisable, on the date of Separation from Service, within ninety days after the date of Separation from Service. In the event of the death of the Participant within the ninety-day period following Separation from Service, his Award may be exercised by his Beneficiary within the one-year period provided in subparagraph 8.02(a) above.
(c)    With respect to an Award which is intended to constitute an Incentive Stock Option, upon Separation from Service, such Award shall be exercisable as provided in Section 422 of the Code.
(d)    In the event that a Participant’s Separation from Service is for Cause, the Participant’s Award Agreements and underlying Awards will terminate immediately upon Separation from Service.

8.03    Acceleration of Exercise TimeThe Administrator, in its sole discretion shall have the right (but shall not in any case be obligated) to permit purchase of shares of Company Common Stock under any Award prior to the time such Award would otherwise become exercisable under the terms of the Award Agreement; provided, however, that an Award shall not be exercisable prior to the first anniversary of the Date of Grant except in the case of the Participant’s death, disability or retirement or in connection with a Change of Control Event.
8.04    Extension of Exercise TimeThe Administrator, in its sole discretion, shall have the right (but shall not in any case be obligated) to permit any Award granted under this Plan to be exercised after its Expiration Date or after the period set forth in Section 8.02, subject, however, to the limitations described in Section 8.01 (c) and (d).
8.05    Prohibited Modification or Extension of OptionsNotwithstanding any provision of the Plan or any Award Agreement to the contrary, no Option may be modified, extended or renewed if such modification, extension or renewal would be considered as the granting of a new Option. Thus, an Option that is designated as an Incentive Stock Option may only be modified, extended, or renewed in compliance with section 424(h) of the Code and the related Treasury regulations under section 1.424-1(e), and an Option that is designated as a Non-Qualified Stock Option or a Performance-Based Option may only be modified, extended, or substituted in compliance with Treasury regulations under section 1.409A-1(b)(5)(v).
8.06    Conditions for ExerciseAn Award Agreement may contain such waiting periods, exercise dates and restrictions on exercise (including, but not limited to, periodic installments which may be cumulative) as may be determined by the Administrator at the Date of Grant.
8.07    Change of Control EventUnless otherwise provided in the Award Agreement, and subject to such other terms and conditions as the Administrator may establish in the Award Agreement, upon the occurrence of a Change of Control Event, irrespective of whether or not an Award is then exercisable, all outstanding Options shall automatically become fully vested and exercisable and all restrictions applicable to any other Award shall lapse and be of no further force or effect.
8.08    Exercise Procedures.
(a)    An Option that is exercisable may be exercised, prior to the Expiration Date of the Award, by the Participant’s delivery to the Officer designed in the Award Agreement of written notice of exercise on any business day, at the Company’s principal office, on the form specified by the Administrator. Such notice must specify the number of shares with respect to which the Option is being exercised and must be accompanied by payment in full of the Purchase Price of the shares of Company Common Stock for which the Option is being exercised plus the amount (if any) of federal and / or other taxes which the Company may, in its judgment, be required to withhold with respect to the Option (or portion thereof) being exercised.
(b)    Notwithstanding the prior provision, the Administrator may (but need not) permit payment to be made by delivery to the Company of either (i) shares of Company Common Stock (including shares issuable to the Participant pursuant to the exercise of the Option), (ii) any combination of cash and shares of Company Common Stock, or (iii) such other consideration as the Administrator deems appropriate and in compliance with applicable law (including payment in accordance with a cashless exercise program under which, if so instructed by the Participant, shares of Company Common Stock may be issued directly to the Participant’s broker or dealer upon receipt of the Purchase Price in cash from the broker or dealer.) In the event that any Company Common Stock shall be transferred to the Company to satisfy all or any part of the Purchase Price, the part of the Purchase Price deemed to have been satisfied by such transfer of Company Common Stock shall be equal to the product derived by multiplying the Fair Market Value as of the date of exercise times the number of shares transferred. The Participant may not transfer to the Company in satisfaction of the Purchase Price (y) a number of shares which when multiplied times the Fair Market Value as of the date of exercise would result in a product greater than the Purchase Price or (z) any fractional share of Company Common Stock. Any part of the Purchase Price paid in cash upon the exercise of any Option shall be added to the general funds of the Company and used for any proper corporate purpose. Unless the Administrator shall otherwise determine, any Company Common Stock transferred to the Company as payment of all or part of the Purchase Price upon the exercise of any Option shall be held as treasury shares.
(c)    A Stock Appreciation Right that is exercisable may be exercised, prior to the Expiration Date of the Award, by the Participant’s delivery to the Officer designed in the Award Agreement of written notice of exercise on any business day, at the Company’s principal office, on the form specified by the Administrator. The Administrator will determine whether the appreciation in a Stock Appreciation Right will be paid in the form of cash, shares of Company Common Stock or a combination of the two, in such proportion as the Administrator deems appropriate. For purposes of calculating the number of shares of Company Common Stock to be issued to the Participant, shares of Company Common Stock will be valued at their Fair Market Value on the date of exercise of the Stock Appreciation Right. If shares of Company Common Stock are issued to a Participant, cash will be paid in lieu of any fractional share.

(d)    In the event that an Option or Stock Appreciation Right is being exercised by a Beneficiary, or any other person pursuant to Section 11.05, appropriate proof of the right of such person to exercise the Option or Stock Appreciation Right must be provided to the Company.
Article IX.
Restricted Share Awards
9.01    Power to Grant Restricted Share RightThe Administrator may grant to any Participant an Award of a Restricted Share Right entitling such Participant to receive shares of Company Common Stock (“Restricted Stock”) in such quantity, and on such terms, conditions and restrictions (whether based on performance standards, periods of service or otherwise) as the Administrator shall determine on or prior to the Date of Grant. The terms of any Award of Restricted Stock granted under the Plan shall be set forth in an Award Agreement.

Any attempt to dispose of Restricted Stock in a manner contrary to the restrictions set forth in the Plan or an Award Agreement will be ineffective.
9.03    Forfeiture of Restricted Share RightsSubject to Section 9.05, an Award of a Restricted Share Right will terminate and any unvested shares will be forfeited unless the Participant (a) remains employed by the Company or a Subsidiary until the expiration of the Restriction Period, and (b) satisfies any other conditions set forth in the Award Agreement. If the Award Agreement so provides, in the case of the Participant’s death, disability or retirement prior to the expiration of the Restriction Period, any Restricted Stock will immediately vest and any restrictions will lapse as of the date of the Participant’s death, disability or retirement.
9.04    Delivery of Shares upon VestingUpon the lapse of the restrictions established in the Award Agreement, the Participant shall be entitled to receive, without payment of any cash or other consideration, certificates for the number of shares of Company Common Stock covered by the Award.
9.05    Waiver or Modification of Forfeiture ProvisionsThe Administrator has full power and authority to modify or waive any or all terms, conditions or restrictions (other than the minimum Restriction Period set forth in Section 9.02) applicable to any Restricted Share Right granted to a Participant under the Plan; provided, that, no modification shall, without consent of the Participant, adversely affect the Participant’s rights thereunder and no modification shall reduce the employment requirement to less than one (1) year, except in the case of the Participant’s death, disability or retirement or a Change of Control Event.

Subject to the provisions of the Plan, the Administrator shall have the sole and complete authority to determine the persons to whom and the time or times at which Other Awards shall be made, the number of shares of Company Common Stock or other securities, if any, to be granted pursuant to such Other Awards, and all other conditions of such Other Awards. Any Other Award shall be confirmed by an Award Agreement executed by the Administrator and the Participant, which agreement shall contain such provisions as the Administrator determines to be necessary or appropriate to carry out the intent of this Plan with respect to the Other Award.

Article XI.
Terms Applicable to All Awards
11.01    Award AgreementThe grant and the terms and conditions of the Award shall be set forth in an Award Agreement between the Company and the Participant.

11.02    Plan Provisions Control Award TermsThe terms of the Plan shall govern all Awards granted under the Plan, and in no event shall the Administrator have the power to grant any Award under the Plan which is contrary to any of the provisions of the Plan. In the event any provision of any Award granted under the Plan conflicts with any term in the Plan as constituted on the Date of Grant of such Award, the term in the Plan as constituted on the Date of Grant of such Award shall control.
11.03    Modification of Award After Grant. Except as provided in Section 4.03, the terms of any Award granted under the Plan may not be changed after the granting of such Award without the express written approval of the Participant and the Administrator. No modification may be made to an Award granted to an Officer except in compliance with Rule 16b‑3. No modification to the terms of an Award may result in the direct or indirect reduction in the Purchase Price or the Exercise Price of the stock right below the Fair Market Value of the shares on the Date of Grant.
11.04    Taxes. The Company is entitled to withhold (or secure payment from the Participant in lieu of withholding) the amount sufficient to satisfy any federal, state and local withholding tax requirements with respect to any amount payable and / or shares issuable under a Participant’s Award, or with respect to any income recognized upon a disqualifying disposition of shares received pursuant to the exercise of an Incentive Stock Option, and the Company may defer payment or issuance of the cash or stock upon exercise or vesting of an Award unless indemnified to its satisfaction against any liability for such tax. The amount of such withholding or tax payment shall be determined by the Administrator (the Participant shall provide to the Company such information as the Company may require to determine the amounts) and, unless otherwise provided by the Administrator, will be payable by the Participant at the time of issuance or payment in accordance with the following rules:
(a)    A Participant shall have the right to elect to meet his or her withholding requirement by: (1) having the Company withhold from such Award the appropriate number of shares of Company Common Stock, rounded out to the next whole number, the Fair Market Value of which is equal to such amount, or, in the case of the cash payment, the amount of cash, as is determined by the Company to be sufficient to satisfy applicable tax withholding requirements; or (2) direct payment to the Company in cash of the amount of any taxes required to be withheld with respect to such Award.
(b)    In the event that an Award or property received upon exercise of an Award has already been transferred to the Participant on the date upon which withholding requirements apply, the Participant shall pay directly to the Company the cash amount determined by the Company to be sufficient to satisfy applicable federal, state or local withholding requirements.
(c)    If permitted under applicable federal income tax laws, a Participant may elect to be taxed in the year in which an Award is exercised or received, even if it would not otherwise have become taxable to the Participant. If the Participant makes such an election, the Participant shall promptly notify the Company in writing and shall provide the Company with a copy of the executed election form as filed with the Internal Revenue Service no later than thirty days from the date of exercise or receipt of Restricted Stock. Promptly following such notification, the Participant shall pay directly to the Company the cash amount determined by the Company to be sufficient to satisfy applicable federal, state or local withholding tax requirements.

11.05    Limitations on TransferExcept as otherwise provided in this Section 11.05, a Participant’s rights and interest under the Plan may not be assigned or transferred other than by will or the laws of descent and distribution. During the lifetime of a Participant, only the Participant personally (or the Participant’s personal representative or attorney-in-fact) may exercise the Participant’s rights under the Plan. The Participant’s Beneficiary may exercise a Participant’s rights to the extent they are exercisable under the Plan following the death of the Participant. Notwithstanding the foregoing, or any other provision of this Plan, a Participant who holds Non-Qualified Stock Options may transfer such Options to his or her spouse, lineal ascendants, lineal descendants, or to a duly established trust for the benefit of one or more of these individuals. Options so transferred may thereafter be transferred only to the Participant who originally received the Options or to an individual or trust to whom the Participant could have initially transferred the Option pursuant to this Section 11.05. Options which are transferred pursuant to this Section 11.05 shall be exercisable by the transferee according to the same terms and conditions as applied to the Participant.
11.06    General RestrictionNotwithstanding anything to the contrary herein, the Company shall have no obligation or liability to deliver any shares of Company Common Stock under the Plan or to make any other distribution of benefits under the Plan unless such delivery or distribution would comply with all applicable laws, rules and regulations, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations of the New York Stock Exchange and Section 409A of the Code.
11.07    Surrender of AwardsAny Award granted under the Plan may be surrendered to the Company for cancellation on such terms as the Administrator and Participant approve; provided, however, that the Administrator may not, without stockholder approval, permit the exchange or surrender of Awards, whether for cash or other Awards, that would directly or indirectly reprice the surrendered Award. Notwithstanding anything to the contrary contained in the Plan, the Administrator may not, without stockholder approval, grant new Awards to a Participant with Exercise Prices or Purchase Prices, as the case may be, lower than the Exercise Prices or Purchase Prices, as the case may be, of current Awards held by such Participant on the condition that such Participant surrender such current Awards to the Company.
11.08    Maximum Awards. The maximum number of shares of Company Common Stock granted to any employee that is a “covered employee” (within the meaning of Section 162(m) of the Code) under the Plan each year is 200,000 shares of Company Common Stock (subject to adjustment as provided in Section 4.03) or $5,000,000 in the case of Awards settled in cash.

(a)    AmendmentThe Board shall have complete power and authority to amend the Plan at any time and to add any other stock based Award or other incentive compensation programs to the Plan as it deems necessary or appropriate and no approval by the stockholders of the Company or by any other person, committee or entity of any kind shall be required to make any amendment; provided, however, that the Board shall not, without the requisite affirmative approval of stockholders of the Company: (i) make any amendment which requires stockholder approval under any applicable law, including Rule 16b‑3 or the Code or which, unless approved by the requisite affirmative approval of stockholders of the Company, would cause, result in or give rise to “applicable employee remuneration” within the meaning of Section 162(m) of the Code with respect to any Performance-Based Option; (ii) reduce the Purchase Price or Exercise Price of any outstanding Option or Stock Appreciation Right; (iii) except as otherwise provided in Section 4.03, cancel any outstanding Option or Stock Appreciation Right in exchange for, or replace any outstanding Option or Stock Appreciation Right with, cash, another Award or any other consideration from the Company; and / or (iv) take any other action that is treated as a repricing under generally accepted accounting principles. No termination or amendment of the Plan may, without the consent of the Participant to whom any Award shall theretofore have been granted under the Plan, adversely affect the right of such individual under such Award. For the purposes of this section, an amendment to the Plan shall be deemed to have the affirmative approval of the stockholders of the Company if such amendment shall have been submitted for a vote by the stockholders at a duly called meeting of such stockholders at which a quorum was present and the majority of votes cast with respect to such amendment at such meeting shall have been cast in favor of such amendment, or if the holders of outstanding stock having not less than a majority of the outstanding shares consent to such amendment in writing in the manner provided under the Company’s bylaws.
(b)    TerminationThe Board shall have the right and the power to terminate the Plan at any time. If the Plan is not earlier terminated, the Plan shall terminate when all shares authorized under the Plan have been issued. No Award shall be granted under the Plan after the termination of the Plan, but the termination of the Plan shall not have any other effect and any Award outstanding at the time of the termination of the Plan may be exercised after termination of the Plan at any time prior to the Expiration Date of such Award to the same extent such Award would have been exercisable if the Plan had not been terminated.

12.02    No Right To EmploymentNo employee or other person shall have any claim or right to be granted an Award under this Plan. Neither the Plan nor any action taken hereunder shall be construed as giving any employee any right to be retained in the employ of the Company or a Subsidiary of the Company.
12.03    Compliance with Rule 16b‑3It is intended that the Plan be applied and administered in compliance with Rule 16b‑3. If any provision of the Plan would be in violation of Rule 16b‑3 if applied as written, such provision shall not have effect as written and shall be given effect so as to comply with Rule 16b‑3, as determined by the Administrator. The Board is authorized to amend the Plan and to make any such modifications to Award Agreements to comply with Rule 16b‑3, as it may be amended from time to time, and to make any other such amendments or modifications as it deems necessary or appropriate to better accomplish the purposes of the Plan in light of any amendments made to Rule 16b‑3.
12.04    Securities Law RestrictionsThe shares of Company Common Stock issuable pursuant to the terms of any Awards granted under the Plan may not be issued by the Company without registration or qualification of such shares under the Securities Act of 1933, as amended, or under various state securities laws or without an exemption from such registration requirements. Unless the shares to be issued under the Plan have been registered and / or qualified as appropriate, the Company shall be under no obligation to issue shares of Company Common Stock upon exercise of an Award unless and until such time as there is an appropriate exemption available from the registration or qualification requirements of federal or state law as determined by the Administrator in its sole discretion. The Administrator may require any person who is granted an Award hereunder to represent and agree with the Company in writing that if such shares are issuable under an exemption from registration requirements, the shares will be “restricted” securities which may be resold only in compliance with applicable securities laws, and that such person is acquiring the shares issued upon exercise of the Award for investment, and not with the view toward distribution.
12.05    CaptionsThe captions (i.e., all section headings) used in the Plan are for convenience only, do not constitute a part of the Plan, and shall not be deemed to limit, characterize or affect in any way any provisions of the Plan, and all provisions of the Plan shall be construed as if no captions have been used in the Plan.
12.06    SeverabilityWhenever possible, each provision in the Plan and every Award Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of the Plan or any Award Agreement is held to be prohibited or invalid under applicable law, then (a) such provision shall be deemed amended to accomplish the objectives of the provision as originally written to the fullest extent permitted by law, and (b) all other provisions of the Plan and every Award Agreement shall remain in full force and effect.
12.07    No Strict ConstructionNo rule of strict construction shall be implied against the Company, the Administrator, or any other person in the interpretation of any of the terms of the Plan, any Award granted under the Plan or any rule or procedure established by the Administrator.
12.08    Choice of LawAll determinations made and actions taken pursuant to the Plan shall be governed by the laws of Michigan and construed in accordance therewith except to the extent such law is preempted by federal law.
12.09    Section 409A of the Code.
(a)    Awards granted under the Plan are intended to be exempt from Section 409A of the Code. To the extent that the Plan or any Award is not exempt from the requirements of Section 409A, the Plan or such Award is intended to comply with the requirements of Section 409A and shall be limited, construed and interpreted in accordance with such intent. Notwithstanding the foregoing, in no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on a Participant by Section 409A or any damages for failing to comply with Section 409A.
(b)    Notwithstanding anything in the Plan or in any Award Agreement to the contrary, to the extent that any amount or benefit that would constitute non−exempt “deferred compensation” for purposes of Section 409A would otherwise be payable or distributable, or a different form of payment (e.g., lump sum or installment) would be effected, under the Plan or any Award Agreement by reason of the occurrence of a Change of Control Event or the Participant's disability or Separation from Service, such amount or benefit will not be payable or distributable to the Participant, and / or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change of Control Event, disability or Separation from Service meet the description or definition of “change in control event,” “disability” or “separation from service,” as applicable, set forth in Section 409A (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a Change of Control Event, disability or Separation from Service. If this provision prevents the payment or distribution of any amount or benefit, or the application of a different form of payment of any amount or benefit, such payment or distribution shall be made at the time and in the form that would have applied absent the Change of Control Event, disability or Separation from Service, as applicable.

(c)    If any one or more Awards granted under the Plan to a Participant could qualify for any separation pay exemption described in Treas. Reg. Section 1.409A−1(b)(9), but such Awards in the aggregate exceed the dollar limit permitted for the separation pay exemptions, the Administrator shall determine which Awards or portions thereof will be subject to such exemptions.
(d)    Notwithstanding anything in the Plan or in any Award Agreement to the contrary, if any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A would otherwise be payable or distributable under this Plan or any Award Agreement by reason of a Participant's Separation from Service during a period in which the Participant is a “Specified Employee”, then, subject to any permissible acceleration of payment by the Administrator under Treas. Reg. Section 1.409A−3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following the Participant's Separation from Service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s Separation from Service (or, if the Participant dies during such period, within 30 days after the Participant’s death); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of such delay period.

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 net cash provided by 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.

Appendix C – 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 provided by / used for 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. Certain financial information has been revised to reflect reclassifications in prior periods to conform to current period presentation.

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 through 2024), than the figures disclosed in the summary compensation table. This is particularly true for our PEO, whose equity awards made up approximately 82% of total compensation for 2020 through 2023, and therefore have a significant impact on our overall "actually paid" compensation.

Core FFO growth$6.81FFO 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 C for the reconciliation of Net Income to Core FFO
Same Property combined NOI growth - MH, RV, Marina, and UK4.3%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, 2023Refer to (1) Appendix C for the reconciliation of Net Income to NOI and (2) table below for the breakdown of NOI
