SUN COMMUNITIES			2021 - PROXY STATEMENT			#

2020 in Review

In 2020, we demonstrated the resilience of our operating model and the desirability of our communities, while further expanding our platform for growth. Despite the challenges presented by the pandemic and the parallel economic impact on regional and national markets, we fared very well. The events of last year amplified the importance of having time-tested procedures and operational protocols in place – which provided us with direction and perspective to confidently navigate a rapidly changing operating environment. We believe the Sun playbook, along with our disciplined approach to capital deployment, created growth opportunities for our Company.

Our initial reaction to COVID-19 was swift and decisive. With no certainty to the duration of the pandemic or the length of time the required closure of 44 of our resorts would continue, we implemented capital conservation strategies, rent hardship programs, team member and guest safety and health protocols and numerous other relief and support measures which can be found in more detail on page 36. In addition, our executives and board members voluntarily forewent their base salaries (except for the minimum amount to comply with certain federal overtime pay rules) and annual board retainer and committee fees for the second quarter of the year.

Our progress in 2020 was underpinned by the dedication of our team and the tailwinds propelling each of our business lines. With this backdrop, our shareholders provided us with the capital to continue our growth initiatives as we completed two sizeable equity raises totaling $1.9 billion. The resilience of our MH and RV resort portfolios allowed us to add over 2,500 revenue producing sites, expand total occupancy by 90 basis points to 97.3 percent, deliver same community NOI growth of 4.0 percent, and Core FFO per share growth of 3.5 percent over the prior year. The demand for affordable housing remained evident throughout the year. Even with the various shelter in place restrictions throughout 2020 and into 2021, applications to live in a Sun Community achieved an all-time high as we received almost 50,000 applications in 2020 and sold nearly 2,900 homes.

Our RV resorts were solid performers even with late openings for 44 of our resorts due to shelter in place restrictions in the second quarter. We experienced record demand in the second half of the year as travelers who wanted an increased level of control and safety chose our resorts for some much-needed respite. This sustained demand translated into an extended season in the fourth quarter where we saw transient RV revenues increase by 18 percent as compared to the same period in 2019.

The stability and resilience of our platform allowed us to continue to pursue our four core investment strategies. The first is reinvestment in our properties to ensure sustained demand and maintain the high quality of our assets. Our second investment strategy is the pursuit of accretive acquisitions – which in 2020 translated to nearly $3.0 billion of investments in MH communities, RV resorts and the addition of another asset class with the acquisition of the Safe Harbor marina portfolio. Third is expansion of our existing communities and resorts where we carefully identify opportunities to add additional sites in properties that exhibit high occupancy and continued strong demand, thereby adding incremental growth and increasing overall returns in assets we already own. Fourth is a greenfield development program where we selectively pursue the construction of new communities and resorts to enhance our long-term growth profile. In 2020, we delivered over 1,300 vacant ground up and expansion sites that will incrementally contribute to our growth in 2021 and beyond.

Our platform for value creation has been expanded with the $2.0 billion acquisition of Safe Harbor, completed in the fourth quarter. This transaction adds a third business line to our platform that shares many of the same characteristics of MH and RV including: high demand but limited supply due to barriers to entry, stable consistent cash flows and resilience through economic cycles. This transaction, along with the subsequent acquisition of seven additional marinas, firmly established Sun as the largest marina owner in the country with 106 marinas across 22 states and also expands our customer base. We anticipate marinas to be a meaningful contributor to our external growth in the coming years given attractive return characteristics and the highly fragmented nature of the sector. The top five marina operators account for less than 5 percent ownership of total marinas providing us with a compelling consolidation opportunity. We have already begun capitalizing on our position as a premier owner by adding $466 million in acquisitions since the close of the transaction. We are excited about our expansion into marinas and are further encouraged by new boater growth where industry sources report a 35 percent increase in first time boat owners year over year. Adding this new outlet for external growth initiatives will support our goal of providing industry-leading growth in the years ahead.

Including Safe Harbor, we invested in 130 operating properties, valued at $3.0 billion which added 45,800 MH and RV sites, and marina wet slips and dry storage spaces to our portfolio. We continued to actively pursue attractive acquisition opportunities of marinas, and MH and RV properties, covering both age-restricted and all age communities.

Equally important to providing superior returns for our shareholders is our commitment to consistently improve our ESG practices. In 2019 we published our inaugural corporate responsibility report and we have continued to augment and add to the programs we initiated at that time. Our priorities include the incorporation of additional renewable energy sources, along with engagement with third party experts to enhance and further develop expected outcomes of our diversity, equity and inclusion efforts.

Highlights of our performance include:

As a reflection of our performance and our ability to generate industry-leading results, we have continually raised our dividend each year since 2016. Concurrently, our stock price has increased on average 19.9 percent per year over the five years ended December 31, 2020, delivering industry leading value to our shareholders as our Core FFO has grown on average 7.7 percent over the same five years.

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.

Compensation Best Practices


			What We Do
R			Pay for Performance: Majority of pay is performance based and not guaranteed.
R			Clawback Policy: We maintain a clawback policy that provides for recovery of incentive compensation in the event of a financial restatement due to material non-compliance with federal securities law.
R			Stock Ownership Guidelines: Executives must comply with stock ownership requirements (6x multiple of salary for CEO; 4x multiple of salary for other executives).
R			Annual Compensation Risk Review: Annually assess risk in compensation programs.
R			Challenging Performance Objectives: Set challenging performance objectives for annual incentives.
R			Double Trigger Change of Control Agreements: An executive is entitled to severance only if, within a specified period following the change of control, he or she is terminated without cause or for good reason, or the successor company does not expressly assume his or her employment agreement.
R			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.


			What We Don't Do
Q			No Hedging: Directors and executive officers are prohibited from hedging their ownership of stock.
Q			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.
Q			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 page 70.

PROPOSAL NO. 1 - ELECTION OF DIRECTORS

SUMMARY

What Am I Voting On?

At the Annual Meeting, eight directors will be elected. The NCG Committee evaluated each nominee in accordance with the committee's charter and our Corporate Governance Guidelines and submitted the nominees to the full Board for approval. All of the nominees were elected to the Board at the 2020 annual meeting, except for Ms. Allen who was appointed to serve as a director by the Board on February 11, 2021. Each of the directors has served continuously from the date of his or her election or appointment to the present time.

The term of each of our directors expires at the Annual Meeting, or 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 2022 annual meeting of shareholders or 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 eight 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.

Board Recommendation: FOR

The Board unanimously recommends that you vote "FOR" each of the eight nominees named below:

In addition to each director's qualifications, experience and skills outlined above and the minimum Board qualifications set forth below under "Consideration of Director Nominees," our NCG Committee looked for certain attributes in each director and based on these attributes, and the mix of attributes of the other incumbent directors, determined that each director should serve on our Board. The NCG Committee does not require that each director possess all of these attributes but rather that the Board is comprised of directors that, taken together, provide us with a variety and depth of knowledge, judgment and experience necessary to provide effective oversight and vision. These attributes include: (a) significant leadership skills as a chief executive officer and / or relevant board member experience, (b) real estate industry experience, (c) transactional experience, especially within the real estate industry, (d) relevant experience in property operations, (e) financial expertise, (f) legal or regulatory experience and (g) legal or regulatory experience in ESG initiatives and implementation.

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

The NCG Committee may solicit recommendations for director nominees from any or all of the following sources: 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 has been recommended to it by a shareholder in compliance with the NCG Committee's procedures for that purpose, and conduct inquiries it deems appropriate into the background of these proposed director candidates. In evaluating proposed director candidates, the NCG 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.

Review of Shareholders' Director Nominees

The NCG Committee's current policy is to review and consider any director candidates who have been recommended by shareholders in compliance with the procedures established from time to time by the NCG Committee. All shareholder recommendations for director candidates must be submitted in writing to our Secretary at Sun Communities, Inc., 27777 Franklin Road, Suite 200, Southfield, MI 48034, who will forward all recommendations to the NCG Committee. All shareholder recommendations for director candidates must be submitted to the Secretary no later than December 1st of the year immediately preceding the year of such annual meeting of shareholders and must include the following information:


}			the shareholder's name, address, number of shares owned, length of period held and proof of ownership,
}			the name, age, business and residential address, educational background, current principal occupation or employment, and principal occupation or employment for the preceding five full fiscal years of the proposed director candidate,
}			a description of the qualifications and background of the proposed director candidate which addresses the minimum qualifications and other criteria for Board membership as approved by the Board from time to time,
}			a description of all arrangements or understandings between the shareholder and the proposed director candidate,
}			the consent of the proposed director candidate to (1) be named in the proxy statement relating to our annual meeting of shareholders and (2) serve as a director if elected at such annual meeting, and
}			any other information regarding the proposed director candidate that is required to be included in a proxy statement filed pursuant to the rules of the SEC.

Director Compensation

Mr. Shiffman, who is our Chairman of the Board and Chief Executive Officer, 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 2020, the Compensation Committee, as part of its review of director compensation, reduced both cash and noncash payments to directors to better align director compensation with that of peers while continuing to appropriately compensate and incentivize directors to maximize shareholder value. The changes for 2020 include:


}			Reduction of Lead Independent Director cash compensation by 38 percent from $40,000 to $25,000.
}			Reduction of Audit Committee member cash compensation by 41 percent from $42,500 to $25,000 per member.
}			Reduction of Audit Committee chair cash compensation by 37 percent from $47,500 to $30,000.
}			No Increase in compensation for Compensation Committee, NCG Committee or Executive Committee members.
}			Reduction of the number of restricted shares awarded to each director to 1,700 restricted shares in 2020 as compared to 3,000 restricted shares in 2019, a 43 percent decrease.

Approved total cash compensation to non-employee directors for 2020 as compared to 2019 was reduced by 9 percent. As part of our COVID-19 expense mitigation efforts in the second quarter of 2020, all directors forewent their second quarter compensation, a 25 percent reduction from their approved 2020 cash compensation. As a result, the total cash compensation to the Board was reduced by 32 percent for 2020 as compared to 2019. The adjustments to both cash and noncash director compensation components in 2020 resulted in the total compensation payable to each individual Board member decreasing as compared with 2019.

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, 2020, each director 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, 2020, the value of average company stock ownership by the Company's non-employee directors was 41 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 2015 to 2020 the total director compensation as a percentage of the Company's total market capitalization declined by 64 percent.

One of the Company's objectives is to provide affordable housing solutions, regardless of geographic location, to residents within our communities. Ensuring there are adequate lending platforms and financing partners is critical for homeowners to be able to finance their manufactured homes. The MH Finance Committee of the Board plays a key role in providing expertise and a network of resources across the real estate and financial services industries to the Company's management in helping meet this objective. Mr. Klein is the Chair of the MH Finance Committee. For nearly two decades, Mr. Klein was the Chief Executive Officer and a director of Origen Financial, Inc., formerly a publicly traded Mortgage REIT that originated, serviced and securitized manufactured home loans. Mr. Klein, as Chair of the MH Finance Committee, has been instrumental in providing oversight and guidance to management in connection with manufactured housing finance matters. In particular, he has been actively involved in the Company's manufactured housing finance joint venture, GTSC, LLC. GTSC is in the business of acquiring, holding, financing, securitizing and selling loans secured, directly or indirectly, by manufactured homes located in the Company's communities. Mr. Klein has broad and deep experience in the origination, servicing, sale and securitization of manufactured housing loans, and has valuable insight into the manufactured housing finance industry and capital markets. Mr. Klein meets at least weekly with management to provide guidance, advice and direction to support the Company's manufactured housing finance activities, and is regularly updated as to GTSC's business, including oversight of negotiations and the structuring of various transactions. The Compensation Committee determined that the retainer fee of $100,000 for Mr. Klein as Chair of the MH Finance Committee is appropriate in light of his significant efforts and because he provides knowledge, experience and a skill set that the Company otherwise does not have. In 2020, the Company paid Mr. Klein a retainer fee of $75,000 for his service as chair of the MH Finance Committee because he forewent his retainer fee for the second quarter as part of the company's COVID-19 cost mitigation efforts.

Mr. Lewis' total director compensation had been the highest compensation for our non-employee directors for several years prior to 2018, due to his service on all standing committees (Audit, Compensation, and NCG), as chair of our Audit Committee, as our Lead Independent Director, and as chair of special committees charged with reviewing corporate structure strategies. In 2020, Mr. Lewis's overall cash compensation paid decreased 40 percent from what he received in 2019, as a result of 2020 compensation committee adjustments described above, and a 25 percent decrease due to COVID-19 related adjustments.

The following table provides compensation for each non-employee member of the Board for the year ended December 31, 2020. The actual compensation reflects our reduction in cash fees from the approved amounts as each of our non-executive directors forwent cash fees in the second quarter of 2020 due to the COVID-19 pandemic.

	Meghan G. Baivier	$	95,625	$	251,549	$	347,174	7,500
	Stephanie W. Bergeron	$	95,625	$	251,549	$	347,174	7,500

		$	658,125	$	1,509,294	$	2,167,419	45,000

(1)The fair value associated with these awards was measured using the closing price of our common stock as of the grant date. Each non-employee director was granted 1,700 shares of restricted stock that will vest on January 8, 2023. For additional information on the valuation assumptions with respect to these grants, refer to Note 10, "Share-Based Compensation," in the Consolidated Financial Statements of our 2020 Annual Report on Form 10-K.

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) February 13, 2020, which was the date these guidelines were last amended, or (ii) the date he or she becomes a director.
}			Until he or she complies with the guidelines, or if he or she fails to comply due to a reduction in our stock price, he or she must retain at least 50 percent of all shares of restricted stock as they vest (not including any newly vested shares sold or withheld to pay applicable taxes).

As of March 12, 2021, each of our directors was in compliance with the stock ownership guidelines.

CORPORATE GOVERNANCE

Effective corporate governance is essential for maximizing long-term value creation for our shareholders. Our beliefs have been grounded in a values-based ethically led organization; this foundation continues to guide our decisions and leadership.

Our governance structure is set forth in our Corporate Governance Guidelines and other key governance documents. These guidelines are reviewed at least annually and updated as appropriate in response to evolving best practices, regulatory requirements, feedback from our annual Board evaluations, and recommendations made by our shareholders and proxy advisors, all with the goal of supporting and effectively overseeing our ongoing strategic growth.

The Company is governed by a Board and Committees of the Board that meet throughout the year.

Board of Directors

Our current directors are Gary A. Shiffman, Tonya Allen, Meghan G. Baivier, Stephanie W. Bergeron, Brian M. Hermelin, Ronald A. Klein, Clunet R. Lewis and Arthur A. Weiss. Under our charter, each of our directors serves for a one-year term or until his or her successor is duly elected and qualified.

The Board is elected by 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 governance 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.

The Board meets quarterly, or more often as necessary. The Board met ten times during 2020 and took various actions by written consent. All directors attended at least 75 percent of the Board and each committee on which they served. All of our then-serving board members attended the 2020 annual meeting.

Board's Role in Risk Oversight

The Board oversees and implements its risk management function several different ways. Specifically, the Audit Committee directs our risk assessment and ERM policies with the Chief Financial Officer and other senior accounting staff, our internal auditor and our independent accountants in conjunction with its review of our financial statements.

Annually, our senior management and executive management teams identify, consolidate and prioritize risks facing the Company. Risk mitigation activities to prevent, mitigate and monitor key risks are formalized and response activities are planned or being planned in the event a risk event does occur. Key risks analyzed include macroeconomic (e.g., economic conditions or access to capital markets) issues, strategic (e.g., acquisitions or regulatory changes) issues and operational (e.g., succession planning, privacy / identity management, data recovery and cybersecurity) issues. As requested, the Company's ERM committee presents to the full Board, who take an active role in risk oversight. From time to time, the Audit Committee discusses with senior management the Company's risk appetite and strategies, risk culture and risk-related business processes.

In addition, the Board discusses the general risks we face, the risk factors disclosed in our annual and periodic reports and our risk management policies with our executive management team from time to time throughout the year. In the event that a specific risk is identified, the Board or the Audit Committee directs management to assess, evaluate and provide remedial recommendations to the Board or the Audit Committee. These efforts have included formalizing the Company's succession planning for executives and key employees, documenting and reviewing emergency preparedness plans to facilitate rapid response to a range of threats and cyber-security risk mitigation plans.

We address potential, cybersecurity breaches and disruptions and disclosure of confidential information by implementing a variety of security measures intended to protect the confidentiality and security of this information including (among others) engaging reputable, recognized firms to help us design and maintain our information technology and data security systems, including testing and verification of their proper and secure operations on a periodic basis. We also maintain cyber risk insurance to provide some coverage for certain risks arising out of data and network breaches. Our senior leadership regularly updates the Board of Directors on security matters and meets at least annually to review program progress and plans, incidents if any, and emerging risks.

Committees of the Board of Directors

Several important functions of the Board may be performed by committees that are comprised of members of the Board. Our bylaws authorize the formation of these committees and grant the Board the authority to prescribe the functions of each committee and the standards for membership of each committee. In addition, the Board appoints the members of each committee. The Board has five standing committees: an Audit Committee, a Compensation Committee, an NCG Committee, an Executive Committee and a MH Finance Committee.

Board Leadership Structure and Independence of Non-Employee Directors

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, from time to time, 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 manufactured home industry and provides for the most efficient leadership of our Board and the Company. The Board believes that Mr. Shiffman, rather than an independent director, is in the best position, as Chairman and 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 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.

Although the Board believes that it is more effective to have one person serve as our Chairman and Chief Executive Officer at this time, it also recognizes the importance of strong independent leadership on the Board. Accordingly, in addition to maintaining a significant majority of independent directors (as described below) 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 consist of members who are independent. There are different measures of director independence under the NYSE independence rules, under Section 16 of the Exchange Act. The Board has reviewed information about each of our non-employee directors and determined that Tonya Allen, Meghan G. Baivier, Stephanie W. Bergeron, Brian M. Hermelin, Ronald A. Klein and Clunet R. Lewis are independent directors. The independent directors meet on a regular basis in executive sessions without management participation. In 2020, 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 Committee Interlocks and Insider Participation

Brian M. Hermelin, Ronald A. Klein and Clunet R. Lewis served as members of the Compensation Committee of our Board during 2020. None of the members of the Compensation Committee has been or will be one of our officers or employees. We do not have any interlocking relationships between our executive officers and the Compensation Committee and the executive officers and compensation committees of any other entities, nor has any such interlocking relationship existed in the past.

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 2004. 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. Except for the Company's use of the airplane described below, which the NCG Committee ratified after such use, the NCG Committee provided prior approval of all such transactions in accordance with the Company's policy.

Environmental, Social and Governance

We believe that commitment to environmental, social and governance stewardship is paramount to creating value for our shareholders, residents and guests, team members and the communities, resorts and marinas in which we live and serve.

In 2020, we prepared a report describing our progress and initiatives regarding sustainability and other ESG matters. For the most recent information regarding our ESG initiatives and related matters, please visit the "ESG" section of our corporate website at www.suncommunities.com/investor-relations/.

Environmental

Current Environmental Initiatives – We are fully committed to reducing our environmental impact across the scope of our operations and through the services we deliver to our residents and guests. We continue to identify opportunities to invest in energy-efficient technology, water efficiency, and waste reduction strategies throughout our communities, resorts and corporate headquarters. By conserving natural resources, reducing our carbon footprint, and participating in efforts to protect the environment through our Sun Unity program, we are striving to achieve our environmental sustainability goals.

} Waste Reduction: Minimize waste through source reduction, reuse and recycling.

•Our waste-reducing initiatives and recycling programs are aimed at minimizing our environmental footprint. Recycling programs in place at 101 communities and resorts, provide residents the opportunity to reduce their environmental footprint. Main office team members participate in paper reduction and recycling programs, as well as electronic equipment and battery recycling.

•Paperless Initiatives: In an effort to reduce paper usage and create efficiency for our customers, we have transitioned several of our paper-based processes to an electronic format. This resulted in estimated paper savings of 1,802,315 pages in 2020.

} Energy conservation: Conserve energy through energy efficiency measures.

•LED Lights Program: At the end of 2020, 95 percent, or over 400 communities and resorts were retrofitted with LED lights. When all of our existing communities and resorts are retrofitted, we expect to save between 30 and 40 million kilowatt hours across the portfolio per year.

•Smart Thermostats Program: Through December 31, 2020, we completed installation of ENERGY STAR certified smart thermostats at 312 locations. Through use of smart scheduling, there is an anticipated savings of 12 percent on heating and 15 percent on cooling costs. We estimate our smart thermostat program will reduce our energy usage by over 5 Million kWh per year and save us over $600,000 per year. We intend to monitor and improve this program during 2021.

•Solar Energy Program: We Invested over $35.0 million in solar energy construction projects covering 32 property locations in California and Arizona. We also Investigated the potential of solar energy solutions in all new ground-up developments and key properties across our portfolio.

} Water Reduction: Conserve water through water efficiency programs.

•We replaced over 40,000 water submeters to a real-time automatic meter reading system to monitor usage, detect leaks, and identify opportunities to further reduce water consumption.

•We reduced water consumption by retrofitting communities with water-efficient shower heads, faucets, toilets and irrigation systems.

Manufactured Housing Industry Environmental Impact – We are uniquely positioned to reduce the environmental impacts across our business through our role in acquiring, developing and expanding manufactured home communities and RV resorts. Manufactured homes are more energy efficient and produce less greenhouse gas emissions and waste than conventional site–homes.


SUN COMMUNITIES			2021 - PROXY STATEMENT			33


SUN COMMUNITIES			2021 - PROXY STATEMENT			#


SUN COMMUNITIES			2021 - PROXY STATEMENT			#

As the nation's premier owner and operator of manufactured housing communities and vacation destinations, we partner with home manufacturers to promote energy and water efficiency, indoor environmental quality and resource efficiency throughout the manufacturing process.

} To drive sustainability and operational efficiency, we only partner with manufacturers that use resources effectively.

} Assembly lines used in the production of manufactured homes allow reduced waste generation through precise cutting and effective machine utilization. Efficiencies that are gained through the manufactured housing development process translate to monetary savings that are passed to us, and ultimately to our resident homeowners and renters.

} Heating and cooling systems in manufactured houses can be up to 30 percent more efficient than standard homes, and manufactured houses feature strict insulation requirements and low-E glass windows. These factors lead to reduced dependency on public utilities for electric and gas services, environmental footprint, and utility cost savings for our residents, as compared to single family standard homes.

Social

We initiate social responsibility efforts largely through our "Sun Unity" program, where we join together to give back to the communities in which we live and serve. Community is woven into the fabric of what we do. The Sun Unity program focuses on:

Sun team members – We are committed to upholding our core values of commitment, intensity, empowerment, accountability and service to all of our stakeholders. These stakeholders include team members, residents and guests, shareholders, and the communities and resorts in which we operate:

} Diversity, equity and inclusion: We believe everyone is unique and are committed to promoting and celebrating those differences. We strive to create an inclusive environment that challenges, inspires, rewards, and transforms our team to be the best and understand the important role diversity plays in fulfilling that goal.

In 2020, we engaged with external stakeholders and third-party expertise to enhance and further develop our implementation of and expected outcomes of our diversity, equity and inclusion efforts.

} Hiring Military Members and Veterans: As of December 31, 2020, active military and veterans made up eight percent of our workforce, an example of our targeted diversity efforts. We honor our military team members by donating to a charitable organization and presenting them with an annual challenge coin. Sun has also made significant charitable contributions to support Homes for Our Troops.

} Training:

•Safety and governance training – We actively seek opportunities to minimize health, safety, and environmental risks to our team members and the residents in the communities and resorts we serve by utilizing safe operating procedures and practices. As part of our commitment to safety, we oversee annual safety training programs for all MH and RV employees to provide tools and safeguards for accident prevention. Our managers are responsible for ensuring that team members receive the appropriate training to perform their jobs safely. 100 percent of Sun team members, other than Safe Harbor employees, received safety training. We plan on ensuring all employees at our recently acquired marinas receive similar training in the future. In addition to safety training, all MH and RV employees are required to complete annual training on key governance topics, including fair housing, harassment-free workplace, diversity and inclusion, and cybersecurity and data protection.

•Road to Success – This training program is available to community and resort managers, assistant managers, and sales managers. This is a hybrid training approach that includes online courses, one-on-one coaching, and in-person training at the main office. It covers a variety of topics that include leadership, communication, culture and daily operations. All content delivered within this program is facilitated in collaboration with our operational leaders, skilled trainers and experienced team members. An average of over 100 team members participate in Road to Success training each year.

•Executive Manager Certification Program – This six-month development program is designed for community and resort managers to increase their knowledge of operations, leadership experience and professional skills supporting future career growth. Participants are challenged with written tests, stretch assignments, live oral exams, mentoring, presentations and interaction with executive leadership. The experience provided gives managers the opportunity to build on their ability to collaborate, manage complex problems and mentor.

•Sun University – Our dedicated Learning and Development team created, and also maintains, Sun University, our corporate training platform. Team member participation is encouraged through various industry-specific conferences, certification courses and other professional development programs. Training and content provided through Sun University has led to an increase in the knowledge of, and accountability for, our daily operations, policies, procedures and professional development. Sun University offers approximately 350 training options through books, online courses, webinars and live sessions.

•Health and Wellness – Our "SunFit Wellness" program provides access to fitness centers, personal trainers, group exercise classes, healthy living information and opportunities to our team members.

Sun residents and guests – To meet the demands of our residents and guests, we offer a diverse range of communities and vacation destinations. At our family-friendly communities, we provide affordable and welcoming neighborhood environments for residents of all ages. Our active age – 55-and-over communities provide the perfect place for retirement living, offering a selection of beautiful homes in exceptional locations to fit every budget. All of our vibrant manufactured home communities offer abundant amenities and services, fostering an active lifestyle, while creating a sense of community. There are also endless possibilities and quality experiences at our vacation destinations, offering unique locations across the U.S. and southern Ontario.

} Our customer service philosophy follows the golden rule, to "treat others the way you want to be treated," and is supported through our strategic approach to customer service for residents and guests at all of our locations.

Community engagement – As a nationwide provider of affordable housing, we believe Sun has a responsibility not only to our employees and residents, but also to the communities in which we live and work. These social responsibility efforts are initiated through our Sun Unity Program, where we come together as a team and give back to these communities for greater impact. 2020 Sun Unity Initiatives included the following efforts:

} Team Member Engagement – The "give back" spirit fostered at our main office also extends to our communities and vacation destinations throughout the U.S. and Canada. At the property level, events are coordinated to involve our residents and guests because together we can make a greater impact. In 2020, through individual and company donations, we were able to support over 115 charitable causes. Here are just a few highlights of Sun Unity events:

•Division 3 / MI – Community managers and leadership in West Michigan volunteered time to pack 1,500 meals for children in need at "Kids' Food Basket" - a non-profit that works to nourish children living at or near the poverty level by providing them with critical meals. Leading up to the event, several communities involved residents by hosting food collection drives for donation and decorating sac supper bags with pictures and inspirational messages.

•River Run RV Resort / CO – Together, our River Run team members and guest volunteers in Colorado volunteered time and resources during the holidays to distribute meals and toiletry bags to 130 individuals in need. Those individuals either have been displaced by fires or didn't have a place to go for the holiday. This was done in partnership with a local charity, "Mountain Family Center."

•Hill Country Cottage and RV Resort / FL – Residents and guest of Hill Country Cottage and RV Resort "flocked" together to raise awareness of and funds for breast cancer assistance through their flamingo flocking event in which residents flocked lawns with lawn ornament flamingos. All funds raised were donated to "Pink Warrior Advocates," a local non-profit directing assisting those that have been diagnosed with breast cancer in Hill Country and the surrounding areas.

•The Ridge and Palm Key Village / FL – The Ridge and Palm Key Village are just two of several locations that pulled together resources to ensure residents had what they needed during the holiday season. Together with local vendors and businesses, the team packed up nonperishable food items to create complete meal kits, resulting in feeding 143 families.

•Rock Crusher Canyon RV Resort / FL – Residents, guests and team members gathered at Rock Crusher Canyon RV Resort for a fun day of raffles, food, baked goods and a craft sale to support "Citrus Country Foundation for Animal Protection." Funds raised were donated to help the foundation continue its mission of ensuring the well-being of animals, primarily within the shelter environment.

} Community Level Engagement

•Sun Unity Scholarship Program – The Sun Scholarship Program was launched in 2017 to support our commitment to investing in the future of our residents and guests. In 2020, Sun awarded scholarships to 40 students in 10 states and over 30 colleges / universities across the U.S. and Canada, with a $10,000 scholarship presented to the top two recipients. Since its launch, our scholarship program has supported over 200 students in their journey toward continued education.

•Together, Sun and our team members donated and matched a total of over $20,000 in 2020 for charitable organizations supporting disaster relief, food security and racial justice and equity.

•Development and Outreach – We engage in community improvement and development programs that align with Sun's vision and goals and are committed to providing opportunities across the locations in which we live and serve.

} American Heart Association – In 2019, we teamed up with the American Heart Association to raise awareness with our team members, guests and residents about Hands-Only CPR. Together, we set out on a mission to provide these lifesaving skills to all property managers by the end of 2020. In 2019, there were four field training sessions completed along with one main office session. Team members who received the training were then equipped to host a training session at their location for our residents and guests, or other team members to participate. As of December 31, 2020, 423 team members received Hands-Only CPR training.

Our Response to COVID-19

} COVID-19 Response: To support the health and well-being of our team members and their families, we provide a variety of resources to assist in navigating the challenges of the COVID-19 pandemic.

} SunStrong – When the pandemic hit hard, our communities came together like we have never seen before.

PROPOSAL NO. 2 - ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

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 2020 executive compensation programs and policies and the compensation paid to our NEOs listed in the Summary Compensation Table below.

"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.

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.

Board Recommendation: FOR

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

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 continue to provide outsized total shareholder returns to our investors. Our executive officers are compensated based on pay for performance and alignment with shareholders' interests. When determining 2020 compensation, the Compensation Committee took into account the level of achievement of certain key financial performance metrics, including but not limited to, TSR, Core FFO, leverage, collection of rents, risk management, ESG initiatives and portfolio growth through acquisitions, joint ventures and development. They also considered the extraordinary efforts of the executive team to lead the Company through the global pandemic while increasing our value creation opportunities through the expansion into marina operations, a new business segment.

During 2020, we continued our track record of delivering industry-leading results for our shareholders, despite a global pandemic and state and local government restrictions on our RV operations throughout the year. We generated Same Community NOI growth of 4.0 percent, added over 2,500 RPS, and delivered annual Core FFO per share growth of 3.5 percent. Our total portfolio achieved a 97.3 percent occupancy level as of December 31, 2020, with our MH portfolio finishing the year at a 96.6 percent occupancy level. Our successful execution of our operational and financial plans has helped us mitigate the impact of COVID-19.

We had a very active and successful year of sourcing and acquiring operating MH communities, RV resorts and marinas. In 2020, we acquired Safe Harbor for $2.0 billion, our largest acquisition to date. The Safe Harbor portfolio was comprised of 99 marinas located in prime coastal markets with over 38,300 total wet slips and dry storage spaces. The marina business shares many of the same characteristics of MH and RV including limited supply, stable cash flows and resilience. Including Safe Harbor, we invested in 130 operating properties, valued at $3.0 billion which added 45,800 MH and RV sites and marina wet slips and dry storage spaces to our portfolio. This represents the largest single year total acquisition value completed in our history. Over 83 percent of our operating asset acquisitions in 2020 were marinas, with the balance comprised of MH communities and RV resorts. We continued to actively pursue attractive acquisition opportunities of marinas, and MH and RV properties, covering both age-restricted and all age communities.

During 2020, we continued our 10-year trend of outperforming many of the leading real estate and market indices. Highlights of our performance include:

Total Shareholder Return

We continued to deliver outstanding performance in 2020. We performed better than the SNL U.S. REIT residential and the MSCI US REIT (RMS) indices on a one-year TSR, and outperformed all disclosed market indices on a three-year and five-year TSRs. We stand out as a leader amongst REITs for delivering TSR results. These TSR results are indicative of our executive team's strategic planning, leadership, execution and dedication to the Company. The execution of our strategic vision has resulted in prolonged TSR outperformance over time as evidenced in the charts below.

Exceptional Growth

Through a thoughtful and disciplined approach, our leadership team has executed a series of acquisition and capital market transactions which have repositioned and transformed our portfolio and created a strong and flexible balance sheet, while generating significant returns for our shareholders.

For over a decade, our executive team has executed on a strategic plan to deliver outsized results by utilizing our operational expertise to create a best-in-class platform of MH communities and RV resorts with a broader geographic range and re-balancing our all-age and age-restricted holdings. The strategy included increasing our ownership of RV resorts, downsizing our exposure in the Midwest and elevating our presence along the east coast of the United States, as well as advancing west to California and Arizona.

In 2020, we entered in the marina business, with the acquisition of Safe Harbor for $2.0 billion, our largest acquisition to date. The Safe Harbor portfolio was comprised of 99 marinas primarily located in prime coastal markets with over 38,300 total wet slips and dry storage spaces. We believe this line of business provides another avenue to generate growth as the asset class shares many of the same compelling characteristics of our MH and RV businesses, such as limited supply, strong demand, stable cash flows and resilience.

Construction Activities

In 2020, we deployed additional capital through the construction of expansion sites and ground-up development projects.

Ground-up Developments – During the year ended December 31, 2020, we completed the construction of over 1,000 MH and RV sites at four ground-up development communities and one redevelopment located in Colorado, North Carolina and South Carolina.

Expansions – We have been focused on expansion opportunities adjacent to our existing communities, and we have developed nearly 5,000 MH and RV expansion sites within the past four years. We added over 300 MH and RV expansion sites at eight properties in 2020. We continue to expand our MH and RV properties utilizing our inventory of owned and entitled land, available for development in 82 communities.

Strong and Flexible Balance Sheet

While transforming our portfolio, we are also focused on maintaining a strong and flexible balance sheet. Through a series of capital market activities we have reduced our leverage, improved our coverage ratios and expanded our liquidity as shown below:

(1)Our Net Debt to Recurring EBITDA ratio is elevated due to the acquisition of Safe Harbor late in 2020 which had the impact of including all of Safe Harbor's debt and only two months of its EBITDA. This ratio will normalize as Safe Harbor's EBITDA is fully presented in our operating results during 2021.

Changes to Executive Compensations Due to COVID-19 Impact

Our executive team has led the company through unprecedented disruption and successfully serviced our residents and guests to the extent possible given government mandated lockdown and restrictions.

In light of the disruption and uncertainty caused by the ongoing COVID-19 pandemic, each of our then existing NEOs forewent his or her base salary (except for the minimum amount to comply with certain federal overtime pay rules) for the second quarter of 2020.

The Compensation Committee met in July to consider the impact of the COVID-19 pandemic on our daily operations and the metrics included in our executive annual incentive program. At their September meeting, the Compensation Committee made revisions to the predefined 2020 executive annual incentive plan for purposes of computing the 2020 cash incentive amount for Mr. Shiffman, Mr. McLaren and Ms. Dearing. Core FFO growth, Recurring EBITDA growth, Same community NOI growth and CNOI were removed from the plan as the pandemic caused adverse impacts, beyond the control of management, which could not have been contemplated when the goals were set in February 2020. The impacts of the pandemic, including the required closure of 44 of our RV resorts for an extended period of time, caused the metrics to be unattainable despite the cost saving measures implemented by management to offset the lost revenue. Rental collection and crisis management metrics were added as they became key metrics relevant to the successful operation of the Company and regularly discussed in calls and virtual meetings with investors subsequent to the onset of the pandemic. The executive team implemented capital preservation strategies including the temporary cessation of certain expansion and development construction activities. This decision led the Compensation Committee to review and revise the metric related to site construction goals by approximately 50 percent. The Compensation Committee determined that achieving construction of approximately half of the originally set targets would be a challenging goal considering the complexity of re-starting construction projects and the uncertainty related to labor, materials and resources. The weighting of each metric within the annual incentive plan, as adjusted, was changed to place emphasis on the measures expected to be key contributors to the successful overall performance of the Company during this unusually challenging year.

Refer to the "Our Response to COVID-19" on page 36 above for additional detail of COVID-19 response.

Compensation Best Practices


			What We Do
R			Pay for Performance: Majority of pay is performance based and not guaranteed.
R			Clawback Policy: We maintain a clawback policy that provides for recovery of incentive compensation in the event of a financial restatement due to material non-compliance with federal securities law.
R			Stock Ownership Guidelines: Executives must comply with stock ownership requirements (6x multiple of salary for CEO; 4x multiple of salary for other executives).
R			Annual Compensation Risk Review: Annually assess risk in compensation programs.
R			Challenging Performance Objectives: Set challenging performance objectives for annual incentives.
R			Double Trigger Change of Control Agreements: An executive is entitled to severance only if, within a specified period following the change of control, he or she is terminated without cause or for good reason, or the successor company does not expressly assume his or her employment agreement.
R			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.


			What We Don't Do
Q			No Hedging: Directors and executive officers are prohibited from hedging their ownership of stock.
Q			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.

Q			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.

Compensation Philosophy and Objectives

The 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 the Company's compensation program are integrated to support our compensation philosophy and objectives.

(1)Fixed compensation component that provides a minimum level of cash to compensate the executive officer for the scope and complexity of the position. Amounts based on an evaluation of the executive officer's experience, position and responsibility as well as intended to be competitive in the marketplace to attract and retain executives.

(2)Variable cash compensation component that provides incentive to the executive officer based on the Compensation Committee's assessment of both annual corporate and individual performance. Measures of corporate performance principally focused on Core FFO and other key operating metrics.

(3)Variable equity compensation component focused on executive retention that provides longer-term motivation with the effect of linking stock price performance to executive compensation.

Bruce D. Thelen

Mr. Thelen's annual cash incentive is based on his overall performance. The basis for his long-term incentive compensation is consistent with that of Mr. Shiffman, Mr. McLaren and Ms. Dearing described above.

Baxter R. Underwood

Mr. Underwood's annual cash incentive is based on his overall performance as determined by the Safe Harbor Executive Committee. He is eligible to participate in an equity incentive program for Safe Harbor's employees under which in any year he may be granted restricted shares of our common stock based on Safe Harbor's performance in the prior calendar year, as measured against certain metrics relating to Safe Harbor's "same-store" growth and acquisitions.

Compensation Processes

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 when determining levels of compensation. In order to implement our executive compensation philosophy, 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

For all NEOs except Mr. Underwood, the Compensation Committee makes all decisions regarding the compensation of executive officers, including cash-based and equity-based incentive compensation programs. The Compensation Committee reviews the performance and determines the annual incentive compensation of the Chief Executive Officer. Together the Compensation Committee and the Chief Executive Officer review the performance of the other executive officers. The Chief Executive Officer 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 executive officers.

The Safe Harbor Executive Committee determines Mr. Underwood's annual cash incentive based on certain goals and objectives. Mr. Underwood is eligible to participate in an equity incentive program for Safe Harbor's employees under which in any year he may be granted restricted shares of our common stock based on Safe Harbor's performance in the prior calendar year, as measured against certain metrics relating to Safe Harbor's "same-store" growth and acquisitions. The Compensation Committee reviews and ratifies Mr. Underwood's incentive compensation.

Role of the Compensation Consultant

In 2020, we engaged, FPL Associates, LP, or FPL, 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. All executive compensation services provided by FPL were conducted under the direction or authority of the Compensation Committee.

Use of Comparative Market Data in Compensation Decisions

As requested by the Compensation Committee, FPL reviewed the most recent publicly available information for companies in our peer group and focused on several main compensation components: base salary, target annual non-equity incentive, and long-term incentive awards (collectively "total remuneration") both on an actual and target basis as well as per individual and in aggregate across the team. The Compensation Committee, in its discretion in setting the compensation elements and levels for the NEOs other than Mr. Underwood, took into consideration this data, as well as other factors.

With the assistance of FPL, we select our peer group 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. From time to time, our peer group is updated based on most recent publicly available market information and the aforementioned factors and application of judgment.

Advisory Vote on Executive Compensation and Compensation Decisions

Advisory Vote on Executive Compensation

The Compensation Committee also considered the results of the advisory vote by shareholders on executive compensation, or the "say-on-pay" proposal, presented to shareholders at our 2020 annual meeting. Last year's say-on-pay proposal received strong shareholder support, at approximately 95 percent of the shares voted approving the executive compensation received in 2019. We will continue to offer an annual non-binding advisory vote on the executive compensation.

Compensation Decisions

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, 2020 continued to focus on the factors described above.

2020 Executive Compensation

For 2020 performance, the compensation mix for our CEO and other NEOs is shown below:

https://cdn.kscope.io/4cccd9f90419812ce1092b9ff32731cf-compensationmix1.jpg

2020 Base Salary (paid in 2020)

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 communities, resorts and marinas 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.

2020 Annual Incentive Award (cash incentive for the 2020 performance award paid 2021)

The annual incentive awards motivate the executive officers to maximize our annual operating and financial performance and reward participants based on annual performance.

Gary A. Shiffman, John B. McLaren and Karen J. Dearing

The Compensation Committee annually reviews performance measures for determining award levels, including growth in key metrics and individual goals to Mr. Shiffman, Mr. McLaren and Ms. Dearing. In each case, actual performance is measured against targets established by the Compensation Committee.

In 2020, the Compensation Committee met in July to consider the impact of the COVID-19 pandemic on our daily operations and the metrics included in our executive annual incentive program. At their September meeting, the Compensation Committee made revisions to the predefined 2020 executive annual incentive plan for purposes of computing the 2020 cash incentive amount for Mr. Shiffman, Mr. McLaren and Ms. Dearing. Core FFO growth, Recurring EBITDA growth, Same community NOI growth and CNOI were removed from the plan as the pandemic caused adverse impacts, beyond the control of management, which could not have been contemplated when the goals were set in February 2020. The impacts of the pandemic, including the required closure of 44 of our RV resorts for an extended period of time, caused the metrics to be unattainable despite the cost saving measures implemented by management to offset the lost revenue. Rental collection and crisis management metrics were added as they became key metrics relevant to the successful operation of the Company and regularly discussed in calls and virtual meetings with investors subsequent to the onset of the pandemic. The executive team implemented capital preservation strategies including the temporary cessation of certain expansion and development construction activities. This decision led the Compensation Committee to review and revise the metric related to site construction goals by approximately 50 percent. The Compensation Committee determined that achieving construction of approximately half of the originally set targets would be a challenging goal considering the complexity of re-starting construction projects and the uncertainty related to labor, materials and resources. The weighting of each metric within the annual incentive plan, as adjusted, was changed to place emphasis on the measures expected to be key contributors to the successful overall performance of the Company during this unusually challenging year. Full base salaries, without regard to salaries forewent during the second quarter of 2020, were used as the basis for annual incentive award calculations.

Individual Goals for Mr. Shiffman – Were focused on strategic leadership of the organization and communication of our mission and values, implementation of systems and processes that assure physical, financial and human resources of our organization, providing strategic planning and guidance for growth through acquisitions and expansions and opportunistically accessing capital markets to fund growth and strengthen the balance sheet. The Compensation Committee determined that for 2020, Mr. Shiffman achieved maximum payout for his individual goals and awarded him $207,551 as a result.

Individual Goals for Mr. McLaren – Were focused on operational execution of the organization associated with our communities and effectively leading our organization to ensure that we maintain being a premiere provider of MH and RV resorts. The Compensation Committee determined that for 2020, Mr. McLaren achieved maximum payout and awarded him $157,500 for his achievements.

Individual Goals for Ms. Dearing – Were focused on evaluation and implementation of strategies associated with our capital requirements and structure including debt and equity transactions, effectively leading our accounting, tax and information technology departments, and creating and communicating along with the other executive officers, our strategic vision. The Compensation Committee determined that for 2020, Ms. Dearing achieved maximum payout for her individual goals and awarded her $127,500 as a result.

As noted previously, the Compensation Committee met in July and again in September to discuss potential revisions to the executive annual incentive plan due to the impact of COVID-19 on the operations of the organization and certain of its financial metrics. At the September meeting, and after significant discussion, the Compensation Committee revised the plan to add metrics being followed closely by management and investors, while removing metrics which were most significantly impacted by the state and local operating restrictions imposed on many of our RV resorts. The weightings of some of the original plan metrics were also changed and the incentive opportunity multipliers were set at reduced levels for new and certain revised metrics. The revised executive annual incentive plan was completed prior to the $2.0 billion acquisition of Safe Harbor and approximately $850.0 million of other RV, MH and marina properties.

After year end, the Compensation Committee met again to review the overall executive compensation program. The Compensation Committee considered the transformative acquisition of Safe Harbor and the executives' commitment and efforts, far in excess of normal circumstances, which were required to successfully navigate through the impact and challenges of COVID-19 in order to perform the significant amount of due diligence, evaluation and inspection of the Safe Harbor properties. This crucial effort was necessitated as a result of the short period of preemptive exclusivity provided by the seller to Sun before marketing the opportunity to the broader market. In recognition of this accomplishment, the Compensation Committee determined it appropriate to revise the annual incentive plan and award a supplemental cash incentive award to each of the executives as noted in the table below.

The table below shows the payout levels achieved by key metric for each of Mr. Shiffman, Mr. McLaren and Ms. Dearing based on the actual results achieved as described above.

The CEO reviews Mr. Thelen's individual contribution and makes an incentive compensation recommendation to the Compensation Committee. Mr. Thelen's maximum annual incentive award opportunity is 100 percent of his base salary. After consideration of the recommendation of the CEO, the Compensation Committee approved an annual incentive award of $382,500 for Mr. Thelen.

Baxter R. Underwood

Mr. Underwood is responsible for managing Safe Harbor. The Safe Harbor Executive Committee reviews Mr. Underwood's individual contribution to the success of Safe Harbor and the Company to determine his annual incentive award. Mr. Underwood's maximum annual incentive award opportunity is 100 percent of his base salary. Mr. Underwood is eligible to participate in an equity incentive program for Safe Harbor's employees under which in any year he may be granted restricted shares of our common stock based on Safe Harbor's performance in the prior calendar year, as measured against certain metrics relating to Safe Harbor's "same-store" growth and acquisitions. The Compensation Committee reviews and ratifies Mr. Underwood's incentive compensation.

In light of his receipt of restricted stock in connection with our acquisition of Safe Harbor and that he was employed by us for only two months of the year, for his service in 2020 Mr. Underwood did not receive a cash incentive and did not receive any restricted stock under the Safe Harbor equity incentive program.

2020 Long-Term Incentive Awards (Equity Awards for the 2019 performance awarded in 2020)

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

Gary A. Shiffman, John B. McLaren and Karen J. Dearing

} Key Considerations

In February 2020, the Compensation Committee granted Mr. Shiffman, Mr. McLaren and Ms. Dearing long-term incentive awards for their 2019 performance as detailed in the tables below. In determining the long-term incentive awards, the Compensation Committee considered the overall financial performance of the Company during 2019, as well as the executive's achievement of his or her individual goals and implementation of the strategic goals of the organization. In particular, we achieved one-year TSR of 50.9 percent compared to 25.8 percent achieved by the MSCI US REIT (RMS) Index. Additional factors included, but were not limited to, Core FFO growth of 7.4 percent compared to 2018, 7.3 percent growth in Same Community NOI compared to 2018, 2.8 percent growth in RPS gains over the prior year 2018, reduction of our net debt to recurring EBITDA leverage ratio to 5.5 times from 5.6 times in 2018 and the acquisition of 47 communities for approximately $815.2 million in 2019.

2021 Long Term Incentive Awards (Equity Awards for the 2020 performance awarded in 2021)

Gary A. Shiffman, John B. McLaren and Karen J. Dearing

In March 2021, the Compensation Committee granted Mr. Shiffman, Mr. McLaren and Ms. Dearing long-term incentive awards for their 2020 performance as detailed in the tables below. In determining the long-term incentive awards, the Compensation Committee considered the overall financial performance of the Company during 2020, as well as the executive's achievement of his or her individual goals, implementation of the strategic goals of the organization, exceptional management during the COVID-19 pandemic and the acquisition and integration of approximately $3.0 billion of properties, including Safe Harbor.

In particular, we achieved one-year TSR of 3.6 percent compared to (7.6) percent achieved by the MSCI US REIT (RMS) Index. Additional factors included, but were not limited to, Core FFO(1) growth of 3.5 percent compared to 2019, and 4.0 percent growth in Same Community NOI compared to 2019.

In recognition of the acquisition of Safe Harbor, the largest acquisition in the Company's history, which was completed during a year with unprecedented management and operational challenges, the Compensation Committee elected to grant a special award to Mr. Shiffman, Mr. McLaren and Ms. Dearing of 10,000 restricted shares each. This transformative acquisition added a new business line, diversified our customer base and also provides for long term external growth opportunities due to the unconsolidated nature of the marina business. Although a certain level of property acquisition is contemplated in the Company's compensation plans, an acquisition of this magnitude and impact is not, and therefore the Compensation Committee granted additional restricted shares subject to certain time and performance vesting metrics as detailed below:

Baxter R. Underwood

In light of Mr. Underwood's 2020 restricted stock award received in connection with the acquisition of Safe Harbor, Mr. Underwood did not participate in the 2021 equity compensation pool that was approved for the employees of Safe Harbor based on 2020 performance and therefore did not receive an equity award in 2021.

CEO Pay Ratio

Median Employee Compensation

As of October 30, 2020, we employed over 5,300 talented individuals in full-time, part-time, seasonal and temporary positions in the United States and Canada. These employees can be categorized into the following areas:


}			Approximately 81 percent of our employees support operations at over 530 communities, resorts, and marinas in positions including but not limited to office assistants, member services specialists, coordinators, housekeepers, groundskeepers and dock hands. These employees are primarily paid on an hourly basis. The median annual total compensation for these employees in 2020 was $26,469.
}			The operational support employees described above are overseen by managers who are led by regional, divisional and senior vice presidents who account for 9.8 percent of our workforce. The median annual total compensation for these employees in 2020 was $78,416.
}			Approximately 9.2 percent 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 2020 was $74,898.

Our median employee, a maintenance technician, was identified from base compensation payroll records as of October 30, 2020, 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.

Total annual compensation for the identified median employee, on a basis consistent with the Summary Compensation Tables requirements and excluding our CEO, was $29,100 for 2020. As a result of the CEO and median employee compensation per above, our CEO pay ratio for 2020 was 572:1.

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 processes and procedures to mitigate such risks. In connection with such enterprise risk management process, 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 its 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 Policy

We have adopted a pledging policy 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.

Position

Annual Base Measure

Chairman and CEO

Base salary

President and other executive officers

Base salary

Covered individuals are required to achieve compliance with these guidelines by five years from the later of the date of:


}			February 13, 2020, which was the date these guidelines were last amended,
}			promotion to the covered position, or
}			start of employment with the Company.

Stock Retention Requirements: Until he or she complies with the guidelines, or if he or she fails to comply due to a reduction in stock price, he or she must retain at least 50 percent of all shares of restricted stock as they vest (not including any newly vested shares sold or withheld to pay applicable taxes).

As of March 12, 2021, each of our NEOs satisfied the requirements of these stock ownership guidelines.

Employment Agreements

Gary A. Shiffman

We and Mr. Shiffman have entered into an employment agreement effective March 29, 2021, under which he serves as our Chief Executive Officer. This agreement supersedes Mr. Shiffman's previous employment agreement, which governed the terms of his compensation in 2020. The initial term of Mr. Shiffman's employment agreement is for five years and is automatically renewable thereafter for successive one-year terms unless either party timely terminates the agreement.

Mr. Shiffman’s annual base salary under his new employment agreement is $900,000, which is the 50th percentile base salary for 2020 of chief executive officers of publicly-traded REITs with market capitalizations over $10 billion, as reported in the 2020 NAREIT Compensation Survey. The annual base salary under his previous employment agreement was $691,837. In addition to his base salary, we may pay Mr. Shiffman an annual incentive in an amount determined by the Compensation Committee, based on individual goals and objectives for Mr. Shiffman, the Company's performance or other criteria the Compensation Committee deems relevant. Although annual incentives are not subject to predetermined contractual caps and are not required to be determined by reference to any pre-determined contractual criteria, the Compensation Committee regularly sets specific performance criteria pursuant to a written plan for Mr. Shiffman adopted before or shortly after the beginning of each year.

The non-competition clauses of Mr. Shiffman's employment agreement generally preclude him from engaging, directly or indirectly, in the same business as the Company, including the development, ownership, leasing, management, financing, or sales of MH communities, RV resorts, manufactured homes or marinas anywhere in the continental U.S. or Canada during the period he is employed by us and for a period of up to 24 months following the period he is employed by us; provided, however, that if Mr. Shiffman is terminated without cause, as defined in his employment agreement, the period of non-competition will be reduced to 12 months following the period he is employed by us.

The annual base salary under his previous employment agreement was $525,000. In addition to his base salary, we may pay Mr. McLaren an annual incentive in an amount determined by the Compensation Committee, based on individual goals and objectives for Mr. McLaren, the Company's performance or other criteria the Compensation Committee deems relevant. Although annual incentives are not subject to predetermined contractual caps and are not required to be determined by reference to any pre-determined contractual criteria, the Compensation Committee regularly sets specific performance criteria pursuant to a written plan for Mr. McLaren adopted before or shortly after the beginning of each year.

The non-competition clauses of Mr. McLaren's employment agreement generally preclude him from engaging, directly or indirectly, in the same business as the Company, including the development, ownership, leasing, management, financing, or sales of MH communities, RV resorts, manufactured homes or marinas anywhere in the continental U.S. or Canada during the period he is employed by us and for a period of up to 24 months following the period he is employed by us; provided, however, that if Mr. McLaren is terminated without cause, as defined in his employment agreement, the period of non-competition will be reduced to 12 months following the period he is employed by us.

Under certain circumstances associated with the termination of this employment, Mr. Underwood may elect to forgo severance compensation and certain benefits in exchange for a release of his obligations under his non-competition clauses.

Clawback

Incentive compensation paid or payable to each of our executive officers will not be deemed to be fully earned and vested, and must be repaid to the extent such incentive compensation becomes subject to clawback pursuant to the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act, any rules promulgated thereunder or the rules and regulations of the NYSE. Our executive officers' incentive-based compensation, including equity-based incentive compensation, is also subject to our Executive Compensation Clawback Policy, under which the Compensation Committee may seek recoupment of incentive compensation if any of our executive officers engages in fraud, willful misconduct or gross negligence that directly caused or otherwise directly contributed to the need for a material restatement of our financial results in order to comply with federal securities laws.

SUN COMMUNITIES			2021 - PROXY STATEMENT			72

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, Ms. Dearing and Mr. Underwood 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 or her employment agreement, or in the case of Mr. Underwood, if we elect not to renew his employment agreement, he or she 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 or her non-competition and confidentiality covenants, each such executive is entitled to continued payment of his base salary for up to 18 months after termination. Under the terms of their previous employment agreements, each of Ms. Dearing and Mr. McLaren was entitled to continued payment of his or her base salary for up to 12 months after any such termination.

If Mr. Shiffman's, Mr. McLaren's, Ms. Dearing's or Mr. Underwood's employment is terminated due to death or disability, he or she or his or her successors and assigns, is entitled to any accrued but unpaid salary, incentive compensation and benefits through the effective date of termination. In addition, Mr. Shiffman, Mr. McLaren, Ms. Dearing and Mr. Underwood are 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 Mr. Shiffman, Mr. McLaren, Ms. Dearing or Mr. Underwood without "cause" (as defined in his or her employment agreement) within two years after the date of such change of control,
}			any of Mr. Shiffman, Mr. McLaren, Ms. Dearing or Mr. Underwood terminates his or her employment for "good reason" (as defined in his or her employment agreement) within two years after the date of such change of control,
}			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 Mr. Shiffman, Mr. McLaren, Ms. Dearing or Mr. Underwood, or
}			in the case of Mr. Underwood, there are less than two years remaining under the term of his employment agreement,

then we are obligated to pay Mr. Shiffman, Mr. McLaren, Ms. Dearing, or Mr. Underwood as applicable, an amount equal to 2.99 times his or her then current base salary (less, in the case of Mr. Shiffman, Mr. McLaren, and Ms. Dearing, amounts paid between the change of control event and the triggering event), and to continue to provide him or her 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 Mr. Shiffman, Mr. McLaren, Ms. Dearing or Mr. Underwood, will become fully vested and immediately exercisable and any stock options may be exercised by him or her 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.

Tax and Accounting Implications

Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code") limits the deductibility on our tax return of compensation over $1.0 million to any of our NEOs.

We believe that, because we qualify as a REIT under the Code and therefore are not subject to federal income taxes on our income to the extent distributed, the payment of compensation that does not satisfy the requirements of Section 162(m) has not and will not generally affect our net income. However, to the extent that compensation does not qualify for deduction of 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 2020, we paid $15,524,949 to Mr. Shiffman, $6,046,977 to Mr. McLaren, $5,176,049 to Ms. Dearing, that were subject to Section 162(m).

409A Considerations

We have also taken into consideration Code Section 409A in the design and implementation of our compensation programs. If an executive is entitled to nonqualified deferred compensation benefits that are subject to Section 409A, and such benefits do not comply with Section 409A, then the benefits are taxable in the first year they are not subject to a substantial risk of forfeiture. In such case, the executive is subject to regular federal income tax, interest and an additional federal income tax of 20 percent of the benefit includible in income.

PROPOSAL NO. 3 - RATIFICATION OF SELECTION OF GRANT THORNTON LLP

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 as our independent registered public accounting firm. The Audit Committee has selected and appointed Grant Thornton LLP as our independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2021. Grant Thornton LLP 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 our best interests 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 LLP 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 LLP. 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 LLP. In the absence of your voting instructions, your broker or nominee may vote your shares for this proposal in its discretion.

Board Recommendation: FOR

The Board unanimously recommends that you vote "FOR" the ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm for 2021.

Report of the Audit Committee

The Board maintains an Audit Committee comprised of four directors. The directors who serve on the Audit Committee are all "independent" for purposes of the NYSE listing standards. The Audit Committee held four formal meetings during the year ended December 31, 2020.

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, LLP, our independent auditors, for the fiscal year ended December 31, 2020;

• 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, 2020, be filed with the SEC.

The Audit Committee has considered and determined that the level of fees of Grant Thornton LLP for provision of services other than the audit services is compatible with maintaining the auditor's independence.

Respectfully Submitted,

Members of the Audit Committee:

Stephanie W. Bergeron (Chair)

Meghan G. Baivier

Brian M. Hermelin

Each share of common stock entitles its holder to cast one vote for each matter to be voted upon.

What is Required to Hold the Annual Meeting?

The presence at the Annual Meeting of the holders of a majority of the shares of common stock outstanding and entitled to vote on the Record Date will constitute a quorum permitting business to be conducted at the Annual Meeting. If you have returned valid proxy instructions or you attend the Annual Meeting, your shares of common stock will be counted for purposes of determining whether there is a quorum, even if you abstain from voting on any or all matters introduced at the Annual Meeting. If there is not a quorum at the Annual Meeting, the shareholders entitled to vote at the Annual Meeting, whether present in person or represented by proxy, will only have the power to adjourn the Annual Meeting until such time as there is a quorum. The Annual Meeting may be reconvened without notice to the shareholders, other than an announcement at the prior adjournment of the Annual Meeting, within 120 days after the Record Date, and a quorum must be present at such reconvened Annual Meeting.

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.


			To vote by Internet: Before the Meeting - go to www.proxyvote.com and follow the instructions there. You will need the 16-digit number included on your proxy card, voter instruction form or notice. During the Meeting - go to www.virtualshareholdermeeting.com/SUI2021. You may attend the meeting via the Internet and vote during the meeting. Have the information that is printed in the box marked by the arrow available and follow the instructions. Voting online during the meeting will replace any previous votes. Even if you plan to attend the meeting virtually, we recommend that you submit your proxy card or voting instructions, or vote by internet, telephone or traditional proxy card by the deadline so that your vote will be counted even if you later decide not to attend the meeting.
			To vote by telephone, shareholders should dial the phone number listed on their voter instruction form and follow the instructions. You will need the 16-digit number included on the voter instruction form or notice.
			If you received a notice and wish to vote by traditional proxy card, you can receive a full set of materials at no charge through one of the following methods: •by internet: www.proxyvote.com; •by phone: (800) 579-1639; or •by email: sendmaterial@proxyvote.com (your material should contain the 16-digit number in the subject line included on the voter instruction form or notice).

The deadline for voting by phone or Internet before the meeting is 11:59 p.m. EDT, on May 18, 2021.

If you complete your proxy via the internet or telephone, or properly sign and return you proxy card, your shares will be voted as you direct. You may specify whether your shares should be voted: (1) for all, some or none of the nominees for director, (2) for or against Proposal No. 2, (3) for or against Proposal No. 3.

We encourage you to provide voting instructions to your brokerage firm by returning a completed proxy. This ensures your shares will be voted at the Annual Meeting according to your instructions. You should receive directions from your brokerage firm about how to submit your proxy to them at the time you receive notice of this Proxy Statement.

Can I Change or Revoke My Proxy?

You may change your proxy at any time before the Annual Meeting by timely delivery of a properly executed, later-dated proxy or by voting at the virtual meeting. You may also revoke your proxy by delivering to our Secretary, so that it is received prior to the time set for commencement of the Annual Meeting, a written notice of revocation bearing a later date than the proxy. However, attendance (without further action) at the Annual Meeting will not by itself constitute revocation or change of a previously granted proxy.

What are the Board's Recommendations?

The Board recommends that you vote:


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 LLP as our independent registered public accounting firm for 2021; and

If no instructions are indicated on your valid proxy, the representative holding your proxy will vote in accordance with the foregoing recommendations of the Board. 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 Can I Receive a Proxy Statement and Annual Report?

Our Proxy Statement and our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC on February 18, 2021, is available electronically via the Internet at www.proxyvote.com. In addition, we will provide without charge to each person to whom this Proxy Statement is delivered, upon written or verbal request, a copy of this Proxy Statement and our Annual Report on Form 10-K for the year ended December 31, 2020, which contains our audited financial statements. Written or telephone requests should be directed to us at 27777 Franklin Road, Suite 200, Southfield, Michigan 48034. Our telephone number is (248) 208-2500.

If you received a notice and wish to vote by traditional proxy card, you can receive a full set of materials at no charge through one of the following methods:

Internet

Call

(800) 579-1639

sendmaterial@proxyvote.com

(your email should contain the 16 digit number in the subject line included on the voter instruction form or notice)

What Vote is Needed to Approve Each Proposal?

Following are the votes needed in order for each proposal to be approved at the Annual Meeting. For all proposals, a quorum must be present at the Annual Meeting.

Proposal No. 1: The affirmative vote by a majority of all the votes cast at the Annual Meeting is necessary for the election of eight directors to serve until our 2022 annual meeting of shareholders, or until their successors shall have been duly elected and qualified.

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 2021.


SUN COMMUNITIES			2021 - PROXY STATEMENT			84

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 do not constitute a vote "for" or "against" any matter being voted on at the Annual Meeting and will not be counted as "votes cast." Therefore, abstentions will have no effect on any of the proposals. Broker "non-votes," or proxies from brokers or nominees indicating that such broker or nominee has not received instructions from the beneficial owner or other entity entitled to vote such shares on a particular matter with respect to which such broker or nominee does not have discretionary voting power, will be treated in the same manner as abstentions for purposes of the Annual Meeting. If you are a beneficial owner whose shares of common stock are held of record by a broker, your broker has discretionary voting authority under NYSE rules to vote your shares on Proposal No. 3 even if the broker does not receive voting instructions from you. However, under NYSE rules, your broker does not have discretionary authority to vote on any of the other proposals without instructions from you, in which case a broker "non-vote" will occur, and your shares of common stock will not be voted on these matters.

How is My Vote Counted?

If the proxy in the form enclosed is duly executed, dated and returned, and it has not been revoked in accordance with the instructions enclosed, the shares of common stock represented by the proxy will be voted by Gary A. Shiffman and Karen J. Dearing, 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 seven nominees for the Board, "FOR" the executive compensation as disclosed in this Proxy Statement, and "FOR" the ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm for 2021, at the discretion of Gary A. Shiffman and Karen J. Dearing, the Board's designated representatives for the Annual Meeting, with respect to such other business as may properly come before the Annual Meeting or any adjournment or postponement of the Annual Meeting. It is not anticipated that any matters other than those set forth in this Proxy Statement will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders. In addition, no shareholder proposals or nominations were received on a timely basis, so no such matters may be brought to a vote at the Annual Meeting.

Who is Soliciting My Proxy?

This solicitation of proxies is made by and on behalf of our Board. Proxies may be solicited by personal interview, telephone, facsimile or email or by our directors, officers and employees. Arrangements may also be made with brokerage houses or other custodians, nominees and fiduciaries to forward solicitation material to the beneficial owners of common stock held of record by such persons, and we may reimburse them for reasonable out-of-pocket expenses incurred in forwarding the material.

We have engaged Alliance Advisors LLC as proxy solicitors, and we anticipate fees and expenses will not exceed $13,000. 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 200, Southfield, Michigan 48034.

APPENDIX A - NON-GAAP FINANCIAL MEASURES

Investors in and analysts following the real estate industry utilize funds from operations ("FFO"), net operating income ("NOI"), and earnings before interest, tax, depreciation and amortization ("EBITDA") as supplemental performance measures. The Company believes that FFO, NOI and EBITDA are appropriate measures given their wide use by and relevance to investors and analysts. NOI provides a measure of rental operations and does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of generally accepted accounting principles ("GAAP") depreciation and amortization of real estate assets. EBITDA provides a further measure to evaluate ability to incur and service debt and to fund dividends and other cash needs. Additionally, FFO NOI and EBITDA are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations used to measure financial position, performance and value.

FFO is defined by the National Association of Real Estate Investment Trusts ("NAREIT") as GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating property, plus real estate related depreciation and amortization, real estate related impairments, 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, impairment and excluding 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. The Company also uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our 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 performance measure or GAAP cash flow from operations as a liquidity measure. 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. Further, 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.

NOI is derived from revenues minus property operating expenses and real estate taxes. 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 GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of the Company's financial performance or GAAP cash flow from operating activities as a measure of our 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.


SUN COMMUNITIES			2021 - PROXY STATEMENT			88

EBITDA as defined by NAREIT (referred to as "EBITDAre") is calculated as GAAP net income (loss), plus interest expense, plus income tax expense, plus depreciated 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 to cover fixed Costs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. 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 divided paying capacity, and should therefore not replace GAAP net income (loss) as an indicated of the Company's financial performance or GAAP cash flow from operating, investing and financing activities as measures of liquidity.
