Explanatory Note

Sun Communities, Inc. is filing this comprehensive Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (this "Annual Report"). This Annual Report contains our audited financial statements for the fiscal years ended December 31, 2023, 2022 and 2021, as well as restated unaudited financial information as of and for the three months ended March 31, 2023, the three and six months ended June 30, 2023 and the three and nine months ended September 30, 2023 (collectively, the "Interim Financial Statements").

Restatement Background

In 2022, we acquired a portfolio of holiday park properties located in the United Kingdom, which we refer to as our Park Holidays business, a reporting unit within our manufactured housing segment. As disclosed in our Current Report on Form 8-K filed with the Securities and Exchange Commission ("SEC") on February 20, 2024, during the course of management's 2023 year-end procedures, we reviewed the controls relating to the valuation of the Park Holidays business and the associated goodwill at March 31, 2023, June 30, 2023 and September 30, 2023. In connection with that review, we concluded that there were triggering events relevant to the valuation of the Park Holidays business, including reduced financial projections and increases in interest rates, that should have been taken into account when preparing the Interim Financial Statements. Management undertook a full review of the valuations and determined that at each of March 31, 2023, June 30, 2023 and September 30, 2023, we should have recognized non-cash impairments to goodwill for the Park Holidays business.
The non-cash goodwill impairments resulted in the following negative adjustments to net income / (loss) in the Interim Financial Statements:

For the three months ended March 31, 2023, non-cash goodwill impairment increased net loss by $15.4 million;
For the three and six month periods ended June 30, 2023, non-cash goodwill impairment changed net income to net loss by the amount of $309.7 million and $325.1 million, respectively;
For the three month period ended September 30, 2023, non-cash goodwill impairment reduced net income by $44.8 million; and for the nine month period ended September 30, 2023, changed net income to net loss by the amount of $369.9 million.

Items Restated in this Form 10-K

This Annual Report reflects changes to the Consolidated Balance Sheets for the periods ended March 31, 2023, June 30, 2023 and September 30, 2023, and the Consolidated Statements of Operations, Comprehensive Loss, Shareholders' Equity and Cash Flows for the quarter and year to date periods ended March 31, 2023, June 30, 2023 and September 30, 2023. Restatements of the summarized consolidated financial information for the quarterly periods are disclosed in Note 22, "Quarterly Financial Data (Unaudited and Restated)," to our accompanying Consolidated Financial Statements.

We do not intend to file amendments to the previously filed Quarterly Reports on Form 10-Q for the quarters ended March 31, 2023, June 30, 2023 and September 30, 2023. Accordingly, investors should rely only on the financial information and other disclosures regarding the restated periods in this Annual Report or in future filings with the SEC, and not on any previously issued or filed reports, earnings releases or similar communications relating to these periods.

See Note 22, "Quarterly Financial Data (Unaudited and Restated)," to our accompanying Consolidated Financial Statements, included in Part II, Item 8 of this Annual Report, for additional information on the restatement and the related consolidated financial statement effects.

Internal Control Considerations

In connection with the restatement, management has assessed the effectiveness of our internal control over financial reporting. Based on this assessment, a material weakness in our internal control over financial reporting was identified, resulting in the conclusion by our principal executive officer and principal financial officer that our disclosure controls and procedures were not effective as of March 31, 2023, June 30, 2023, September 30, 2023, and that our internal control over financial reporting and disclosure controls and procedures were not effective as of December 31, 2023. Management is taking steps to remediate the material weakness in our internal control over financial reporting, as described in Part II, Item 9A, Controls and Procedures of this Annual Report.

SUN COMMUNITIES, INC.
PART I

ITEM 1. BUSINESS

GENERAL OVERVIEW

Sun Communities, Inc., and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership, a Michigan limited partnership (the "Operating Partnership"), Sun Home Services, Inc., ("SHS"), Safe Harbor Marinas, LLC ("Safe Harbor"), and the entities through which we operate our holiday parks business in the United Kingdom ("UK") (collectively, "Park Holidays"), are referred to herein as the "Company," "SUI," "we," "us," or "our."

We are a fully integrated real estate investment trust ("REIT"). We own manufactured housing ("MH") and recreational vehicle ("RV") communities and marinas in the United States ("U.S."), the UK and Canada (marinas and, together with MH and RV, the "properties"). We self-administer, self-manage, and operate or hold an interest in, and develop the majority of our properties, and a select number of our communities are operated by independent third party contractors on our behalf under management agreements. Others are operated by lessees under ground lease arrangements. Together with our affiliates and predecessors, we have been in the business of acquiring, operating, developing and expanding MH and RV communities since 1975 and marinas since 2020.

We lease individual parcels of land ("sites"), with utility access for the placement of manufactured homes and RVs to our MH and RV customers. Our MH communities are designed to offer affordable housing to individuals and families, while also providing certain amenities. In the UK, our MH communities are referred to as holiday parks and are predominantly located at irreplaceable seaside locations in the south of England. Our RV communities are designed to offer affordable vacation opportunities to individuals and families complemented by a diverse selection of high-quality amenities.

The majority of our marinas are concentrated in coastal regions. Our marinas offer wet slip and dry storage space leases, end-to-end service (such as routine maintenance, repair and winterization), fuel sales and other high-end amenities. These services and amenities offer convenience and resort-quality experiences to our members and guests.

As of December 31, 2023, we owned and operated, directly or indirectly, or had an interest in, a portfolio of 667 developed properties located in the U.S., the UK and Canada, including 353 MH communities, 179 RV communities and 135 marinas. As of December 31, 2023, the properties contained an aggregate of 227,340 developed sites comprised of 118,430 developed MH sites, 32,390 annual RV sites (inclusive of both annual and seasonal usage rights), 28,490 transient RV sites, and 48,030 wet slips and dry storage spaces. Additionally, we own or control land to support developing and expanding over 17,980 additional MH and RV sites suitable for development.

Through SHS, a taxable REIT subsidiary, we market, sell, and lease new and pre-owned homes to current and future residents in our MH communities. The operations of SHS support and enhance our occupancy levels, property performance and cash flows.

Our executive and principal property management office is located at 27777 Franklin Road, Suite 300, Southfield, Michigan 48034 and our telephone number is (248) 208-2500. We also have principal offices in Dallas, Texas, and in Bexhill-on-Sea, East Sussex, UK. We have regional property management offices throughout the U.S. We employed an aggregate of 6,780 full and part time employees as of December 31, 2023.

Our website address is www.suninc.com and we make available, free of charge, on or through our website all of our periodic reports, including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and current reports on Form 8-K, as soon as reasonably practicable after we file such reports with the SEC. Additionally, the SEC maintains a website at https://www.sec.gov, that contains reports, proxy information statements and other information about us.

SUN COMMUNITIES, INC.
STRUCTURE OF THE COMPANY

The Company is a REIT and the general partner of the Operating Partnership. As the sole general partner of the Operating Partnership, we generally have the power to manage and have complete control over the conduct of the Operating Partnership's affairs and all decisions or actions made or taken by us as the general partner pursuant to the partnership agreement are generally binding upon all of the partners and the Operating Partnership.

The Operating Partnership is structured as an umbrella partnership REIT ("UPREIT"). We conduct substantially all of our operations through the Operating Partnership, which, directly or indirectly through other subsidiaries, owns substantially all of our assets. This UPREIT structure enables us to comply with certain complex requirements under the federal tax rules and regulations applicable to REITs, and to acquire properties in transactions that defer some or all of the sellers' tax consequences. The financial results of the Operating Partnership and our other subsidiaries are consolidated in our Consolidated Financial Statements. The financial results of the Operating Partnership include certain activities that do not necessarily qualify as REIT activities under the Internal Revenue Code of 1986, as amended (the "Code"). We have formed taxable REIT subsidiaries, as defined in the Code, to engage in such activities. We use taxable REIT subsidiaries to offer certain services to our residents and engage in activities that would not otherwise be permitted under the REIT rules if provided directly by us or by the Operating Partnership. The taxable REIT subsidiaries include our home sales business, SHS, which provides manufactured home sales, leasing, and other services to current and prospective tenants of our properties. Currently, all of our UK operations are conducted through taxable REIT subsidiaries.

Under the partnership agreement, the Operating Partnership is structured to make distributions with respect to certain of the Operating Partnership units ("OP units") at the same time that distributions are made to our common shareholders. The Operating Partnership is structured to permit limited partners holding certain classes or series of OP units to exchange those OP units for shares of our common stock (in a taxable transaction) and achieve liquidity for their investment.

SUN COMMUNITIES, INC.
As of December 31, 2023, we owned 95.4% of all of the OP Units and the limited partners of the Operating Partnership own the rest. The following table sets forth:

The various series of OP units and the number of units of each series outstanding as of December 31, 2023;
The relative ranking of the various series of OP units with respect to rights to the payment of distributions and the distribution of assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Operating Partnership;
The number of shares of our common stock issuable upon the exchange, directly or indirectly, of each OP unit of the applicable series;
The annual distribution rate on each series of OP units; and
Information regarding the terms of redemption rights for each series of OP units, as applicable.

REAL PROPERTY OPERATIONS

Throughout this report, we use the terms resident to represent a "resident" in the U.S. and a "customer" in the UK.

An MH community is a residential subdivision with sites for the placement of manufactured homes, related improvements and amenities. Manufactured homes are detached single-family homes that are produced off-site by manufacturers and installed on site within the community. Manufactured homes are available in a wide array of designs, providing owners with a level of customization generally unavailable in multi-family housing complexes. Modern MH communities contain improvements similar to other garden-style residential developments, including centralized entrances, paved streets, curbs, gutters and parkways. In addition, these communities also often provide a number of amenities, such as a clubhouse, a swimming pool, basketball courts, shuffleboard courts, tennis courts and laundry facilities.

An RV community is a resort with sites for the placement of RVs for varied lengths of time. RV communities may also provide vacation rental homes and may include a number of amenities such as restaurants, golf courses, swimming pools, water parks, tennis courts, fitness centers, planned activities and spacious social facilities.

From 2021 to 2023, we rebranded 151 RV communities under the "Sun Outdoors" umbrella guided by our belief that the Sun Outdoors brand supports our competitive advantage in the outdoor market. Implementation consisted of the conversion of the communities' digital presence (website, social media, reservation software and other internal systems) and the replacement of signage at the communities. Sun Outdoors offers RV sites, vacation rentals and tent camping with world-class amenities in the U.S. and Canada.

A marina is a specially-designed harbor that can be located on oceans, lakes, bays or rivers and typically includes dry storage systems that provide storage solutions for the placement of vessels ranging in size from small boats to super yachts for varied lengths of time. Dry storage systems also allow for the required maintenance of the vessels that we store. Marinas also provide ancillary services, such as fuel stations, ship stores, restaurants, swimming pools, cabin and lodging rentals, boat rentals, tennis courts, fitness centers, shower and laundry facilities, planned activities and other services to create a robust member experience.

Renters at our MH and RV communities lease the site on which a manufactured home, RV or vacation rental home is located. We typically own the underlying land, utility connections, streets, lighting, driveways, common area amenities, and other capital improvements and are responsible for enforcement of community guidelines and maintenance. In certain MH and RV communities, we do not own all of the underlying land and operate the communities pursuant to ground leases. Certain communities provide water and sewer service through public or private utility companies, while other communities provide these services to residents from on-site facilities. Each owner of a home within our properties is responsible for the maintenance of the home and leased site. As a result, our capital expenditure needs tend to be less significant relative to multi-family rental apartment complexes.

Renters at our marinas lease the wet slip or dry storage space on which a vessel is stored. We typically own the underlying land, building improvements, dock improvements, site improvements and other on-site amenity structures. Because we own the facilities and improvements on the land or submerged land at those marinas, we are responsible for the capital improvements and maintenance. In certain marinas, we do not own all of the underlying land and operate the marinas pursuant to ground leases.

We compete with other available MH and RV communities, and alternative forms of housing (such as on-site constructed homes, apartments, condominiums and townhouses) as they provide housing alternatives to potential tenants of MH and RV communities. We also compete with other available marinas in the U.S.

PROPERTY MANAGEMENT

Our property management strategy emphasizes intensive, detail-oriented, hands-on management by dedicated, on-site MH and RV community and marina managers. We believe our focus on creating an exceptional resident, guest and member experience creates a competitive advantage. It enables us to continually monitor and address concerns, the performance of competitive properties and local market conditions. As of December 31, 2023, of our 6,780 employees, 1,192 were located on-site as property managers, and of those, 99.3% were full-time employees.

4

SUN COMMUNITIES, INC.
Our MH and RV property managers in the U.S. and Canada are overseen by our Chief Operating Officer, four Senior Vice Presidents of Operations and Sales, 11 Divisional Vice Presidents and 43 Regional Vice Presidents. Each Regional Vice President oversees one to 16 properties and is responsible for regular property inspections, oversight of property operations and sales functions, semi-annual market surveys of competitive communities and interaction with local manufactured home dealers. Each property manager performs regular inspections in order to monitor the physical condition of properties and to effectively address tenant concerns. In addition to an on-site manager, each district or property has on-site maintenance personnel and management support staff. We hold mandatory training sessions for all new property management personnel to ensure that policies and procedures are executed effectively and professionally. All of our property management personnel participate in on-going training to ensure that changes to policies and procedures are implemented consistently. Our internal training program has led to increased knowledge and accountability for daily operations and policies and procedures.

Park Holidays' MH and RV property managers are overseen by a Chief Executive Officer of Park Holidays, a Chief Operating Officer, and two Regional Operations Directors.

Our marina business is overseen by a Chief Executive Officer of Safe Harbor, two Executive Vice Presidents of Operations, two Senior Vice Presidents of Operations and 15 Regional Vice Presidents who are responsible for regular marina inspections and oversight of operations.

HOME SALES AND RENTALS

We are engaged in the marketing, selling and leasing of new and pre-owned homes to current and future residents in our MH communities through SHS in the U.S. and Park Holidays in the UK. Because tenants often purchase a home already on-site within a community, the services SHS and Park Holidays provide enhance occupancy and property performance. Additionally, because many of the homes on the properties are sold through SHS and Park Holidays, better control of home quality in our communities can be maintained than if sales services were conducted solely through third-party brokers.

SHS also leases homes to prospective tenants. As of December 31, 2023, SHS's portfolio consists of over 10,230 occupied leased homes. New and pre-owned homes are purchased for our Rental Program. Leases associated with our Rental Program generally have a term of one year. The Rental Program requires management of costs associated with repair and refurbishment of these homes as the tenants vacate and the homes are re-leased. In 2023, we received over 51,200 applications to live in our MH and RV properties, providing a significant "resident onboarding" system that allows us to market the purchase of a home to qualified applicants. Through our Rental Program, we demonstrate our product and lifestyle to the renters, while monitoring their payment history and converting qualified renters to owners.

Park Holidays also rents homes for short-stays to allow people to experience the community park and facilities. Their short-stay experiences may, in turn, lead guests to ultimately purchase a home in a Park Holidays community. Holiday makers drive the pipeline for future home sales opportunities.

Our home sales and leasing operations compete with other national, and local MH dealers and MH community owners and other holiday park owners in the U.S. and UK.

MARINA MEMBER BASE

We are engaged in the marketing and leasing of wet slips and dry storage spaces and have approximately 48,000 members throughout our marina network as of December 31, 2023.

SUN COMMUNITIES, INC.
SITE LEASES OR USAGE RIGHTS

Typical tenant leases for MH sites in the U.S. are year-to-year or month-to-month, renewable upon the consent of both parties, or, in some instances, as provided by statute. Certain of our leases, mainly at our Florida and California properties, are tied to the consumer price index or other indices as they relate to rent increases. Generally, market rate adjustments are made on an annual basis. These leases are cancellable for non-payment of rent, violation of community rules and regulations or other specified defaults. During the five calendar years ended December 31, 2023, on average less than 1.0% of the homes in our MH communities have been removed by their owners and 6.1% of the homes have been sold by their owners to a new owner who then assumes rental obligations as a community resident. On average, our residents remain in our communities for approximately 15 years. Site license fees for MH sites in the UK are for a term of 20, 30 or 40 years depending on the product originally purchased. The holiday homeowner must pay an annual site fee for their holiday home to remain on the property. On average, Park Holidays homeowners remain in the communities for over seven years.

Typical resident agreements for RV sites are year-to-year or from move-in date until the end of the current calendar year. Generally, increases and market rate adjustments are made on an annual basis. These agreements are cancellable for non-payment of rent, violation of community rules and regulations or other specified defaults.

Leases for wet slips and dry storage spaces at our marinas are year-to-year, season-to-season, month-to-month, or transient by night, renewable upon the consent of both parties. On average, our members maintain leases in our marinas for approximately 8.3 years.

ACQUISITIONS

During the year ended December 31, 2023, we acquired one MH community with 68 sites and 72 development sites, and one marina with 24 wet slips and dry storage spaces, for a total purchase price of approximately $107.0 million.

EXPANSION / DEVELOPMENT

During the year ended December 31, 2023, we acquired four land parcels located in the U.S. and one land parcel in the UK for the potential development of over 1,350 sites, expanded our existing communities by over 440 sites and delivered 360 sites at five ground-up development properties.

REGULATIONS AND INSURANCE

General

MH, RV and marina properties are subject to various laws, ordinances and regulations, including regulations relating to recreational facilities such as swimming pools, clubhouses and other common areas. Each property has the necessary operating permits and approvals.

Insurance

With increased insurance claims across the industry and other market conditions, it has been more difficult to obtain insurance, in particular property insurance covering named windstorms, business interruption, flood and earthquake insurance. With fewer insurers willing to provide policies, and policies increasingly including lower coverage limits, higher deductibles and higher premiums, we have changed our insurance purchasing philosophy and strategy resulting in us self-insuring a greater risk to offset insurance market fluctuations. Our management believes that the properties are covered by adequate comprehensive liability, fire, property, business interruption, general liability, and (where appropriate) flood and earthquake insurance through a combination of our self-insurance partially covering our risk and insurance provided by reputable companies with commercially reasonable deductibles and limits. We maintain a blanket policy that covers all of our properties. We have obtained title insurance insuring fee title to the properties in an aggregate amount which we believe to be adequate. Claims made to our insurance carriers that are determined to be recoverable are classified in other receivables as incurred.

SUN COMMUNITIES, INC.
HUMAN CAPITAL

Human capital management is key to our success and focuses on diversity, equity and inclusion, employee retention and talent development practices. We are committed to building an equitable and inclusive culture that inspires and supports the growth of our employees, serves our communities and shapes a more sustainable business. The most significant measures and objectives that we focus on in managing our business and our related human capital initiatives include the following:

Culture

We foster a growth culture that is grounded in our vision and culture statements: We are an inspired, engaged and collaborative team committed to providing extraordinary service to our residents, guests and team members. Together as one team, we embrace the following seven key behaviors that make our company a great place to work:

Live the Golden Rule: Treat others the way you want to be treated;
Do the right thing;
We over me;
Nothing changes if nothing changes;
Mindset is everything;
Keep it simple; and
Be yourself and thrive.

Leadership, Talent, Training and Development

We expect our leaders to be role models and lead in a way that enables our organization to achieve success. Our strategy is anchored in promoting the right internal talent and hiring the right external talent for career opportunities across our organization. We are focused on hiring and developing talent that mirrors the markets we serve, and investing in learning opportunities and capabilities that equip our workforce with the skills they need while improving engagement and retention.

Our internal training program offers over 310 courses to our team members on a range of topics, including leadership, communication, inclusion and diversity, software and operations. Our internal training program has led to increased knowledge and accountability for daily operations and policies and procedures. In 2023, team members logged nearly 85,700 hours of training.
We hold ongoing training sessions for all property management personnel to ensure that policies and procedures are executed effectively, professionally and consistently.

We are dedicated to attracting, developing and retaining our talent, focusing our efforts on ensuring that the returning seasonal team member pipeline remains robust each year and our annual talent management processes focus on the professional development of salaried team members. As of December 31, 2023, nearly 12% of our employees had over 10 years' tenure.

Our compensation philosophy, aimed to apply merit-based, equitable compensation practices, is designed to attract and retain top talent. For eligible team members, we offer competitive salary, health, welfare, retirement and pet insurance benefits, tuition reimbursement and rent / vacation discounts at our properties.

Inclusion, Diversity, Equity and Accessibility ("IDEA")

We make it a priority to recognize and appreciate the diverse characteristics that make individuals unique in an atmosphere that promotes and celebrates individual and collective achievement. We believe it's not just about gender or race, but about being diverse in thoughts, life and work experiences. Our inclusive environment challenges, inspires, rewards and transforms our team to be the best. We do not tolerate harassing, discriminatory or retaliatory conduct as such conduct is prohibited and inconsistent with our policies, practices and philosophy. We continue to put our resources and energy into strategies and initiatives to create a more equitable environment.

SUN COMMUNITIES, INC.
Workforce Diversity

We believe we are a stronger organization when our workforce represents a diversity of ideas and experiences. We value and embrace diversity in our employee recruiting, hiring and development practices. As of December 31, 2023, 40% of our employees were female, 23% of our employees (excluding those in Canada and the UK) were racially or ethnically diverse, and 44% of our employees were aged 50 years and older, with approximately 24% being aged 60 years and older.

Training and Resources

We offer training and resources on diversity, equity and inclusion to our employees. Diversity education and training programs for our team focus on unconscious bias, gender identity and transitions, generational differences, religion in the workplace, and self-awareness and self-assessments.

Pay Equity

We are committed to providing a total compensation package that is market-based, performance driven, fair and internally equitable. Our goal is to be competitive both within the general employment market as well as with our competitors in the real estate industry, with our strongest performers being paid more.

Compensation for each position is determined by utilizing reliable third-party compensation surveys to obtain current market data. Additionally, position descriptions and compensation are routinely reviewed for market competitiveness.
On an annual basis, the performance of all team members is evaluated and merit increases are allocated based on performance. This process ensures equitable performance review and corresponding pay practices that attract, retain and reward top talent.

Business Integrity

Our Code of Conduct and Business Ethics is grounded in our commitment to do the right thing. It serves as the foundation of our approach to ethics and compliance, and our anti-corruption compliance program is focused on conducting business in a fair, ethical and legal manner.

Workplace Health and Safety

We actively seek to minimize health, safety and environmental risks to our team members, residents, and guests by utilizing safe operating procedures and practices:

As part of our commitment to safety, we oversee annual safety training programs for 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;
All team members participate in safety training during the onboarding process, and thereafter, team members in the field complete an annual safety training course; and
We uphold a safe workplace by complying with safety and health laws and regulations, maintaining internal requirements and remediating risks. Senior leadership review safety concerns throughout the year on regular site visits, and we also conduct comprehensive safety inspections annually on a subset of properties on a rolling basis.

SUN COMMUNITIES, INC.
ENVIRONMENTAL, SOCIAL AND GOVERNANCE ("ESG"): OUR COMMITMENT TO A SUSTAINABLE FUTURE

We continue to embrace a company-wide commitment to ESG practices and procedures implemented through executive commitments, sponsorship of various programs and our everyday business practices.

Environmental

The International Energy Agency ("IEA") estimates that the energy usage related to operating buildings (commercial and residential) accounts for 26% of global energy-related emissions. In recognition of the impact buildings have on global annual greenhouse gas ("GHG") emissions, in 2022 we adopted goals to achieve Carbon Neutrality by 2035 inclusive of ISO 14064:1 ("ISO 14064") categories 1, 2, 3 and 4, and Net Zero Emissions by 2045 (inclusive of all five ISO 14064 categories).

The main tactics we intend to use to achieve our commitment will be seen across all our properties as we work toward achieving our climate change goals through various means, including:

Renewable Energy – Expanding the use of renewable energy throughout our portfolio through additional on-site energy generation, and the consideration for purchase of off-site generated energy and Renewable Energy Certificates (RECs);
Energy Efficient Buildings – Increasing the use of certified energy efficient manufactured homes, including ENERGY STAR®, in our communities as well as energy-efficient lighting and building control systems;
Waste – Reducing total waste and increasing diversion from landfills by evaluating all disposal options locally available, including recycling, and adopting the best solution(s) at each property; and
Material Procurement – Partnering with our supply chain and consultants to collect emissions data on products and services.

During 2023, we completed a top ESG priority by expanding our data coverage to encompass our UK operations and Marina segment. Through collection of primary source data (e.g., utility bills and invoices) and accepted estimation methods, we were able to complete full reporting of all direct and indirect source emissions.

We are fully committed to reducing our environmental impact through investments in energy-efficiency technology, water conservation initiatives and waste reduction strategies implemented across the scope of our operations and through the services we deliver to our residents and guests.

Social

In addition to our commitments and practices discussed above, in the "Human Capital" section, we recognize the important social opportunity we have to provide housing that is both affordable and sustainable. Our business contributes to a vitally important function in our economy by providing high-quality, affordable housing that accommodates all-age and age-restricted communities. Our homes provide more space at less cost per square foot compared to other options.

According to Zillow.com's September 2023 rent index, the average MH site rent in a Sun community is approximately 50% less than the monthly cost of other rental options.

By providing safe, well-located and affordable communities, Sun is expanding the opportunity for home ownership, despite an ever-increasing housing affordability gap.

Another way we support the communities in which we operate is through volunteerism and sponsorship efforts. In 2023, our team members reported approximately 16,000 volunteer hours, an increase of 72% compared to the prior year.

Governance

Aligning Company policies and procedures with the interests of all stakeholders is always a priority for Sun. Among the best practices and policies described in our annual ESG reports and on our website, www.suninc.com, our Code of Conduct and Business Ethics policy serves as the foundation for our approach to ethics and compliance, and our anti-corruption compliance program is focused on conducting business in a fair, ethical and legal manner. Additionally, our publicly available policies outline the expectations we have of supply chain vendors and service providers with whom we partner to operate our properties.

ITEM 1A. RISK FACTORS

Our prospects are subject to certain uncertainties and risks. Our future results could differ materially from current results, and our actual results could differ materially from those projected in forward-looking statements as a result of certain risk factors. These risk factors include, but are not limited to, those set forth below, other one-time events, and important factors disclosed previously and from time to time in our other filings with the SEC.

RISKS RELATED TO THE RESTATEMENT OF OUR PRIOR FINANCIAL STATEMENTS

We have identified a material weakness in our internal control over financial reporting which resulted in a material misstatement in certain of our previously issued interim unaudited consolidated financial statements, and we cannot provide assurances that this weakness will be effectively remediated or that additional material weaknesses will not occur in the future.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

During the preparation of this Annual Report, we identified a material weakness in our internal control over financial reporting relating to the design of management's review controls over assessments of goodwill impairment for our Park Holidays business. As a result of this weakness, we concluded that our disclosure controls and procedures were not effective as of March 31, 2023, June 30, 2023 and September 30, 2023 and that our internal control over financial reporting and disclosure controls and procedures were not effective as of December 31, 2023. We have restated our interim unaudited consolidated financial statements as of March 31, 2023, June 30, 2023 and September 30, 2023 in this Annual Report.

We are actively engaged in the planning for, and implementation of, remediation efforts to address this material weakness but there can be no assurance that those efforts will be successful. A material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively. If we do not remediate this material weakness in a timely manner, or if additional material weaknesses in our internal control over financial reporting are discovered, they may adversely affect our ability to record, process, summarize and report financial information timely and accurately and our financial statements may contain material misstatements or omissions. In addition, we may experience delays or be unable to meet our reporting obligations or to comply with SEC rules and regulations, which could result in investigations and sanctions by regulatory authorities. Any of these results may, among other adverse consequences, cause investors to lose confidence in our reported financial information, incur the expense of remediation, result in regulatory scrutiny, litigation, investigations or enforcement actions, limit our ability to access the capital markets, lead to a decline in our stock price, and otherwise have a material adverse effect on our business, financial condition, results of operations and cash flows.

For more information relating to the Company's internal control over financial reporting, the material weakness described above and the remediation activities undertaken by us, see "Controls and Procedures" in Part II, Item 9A, of this Annual Report on Form 10-K.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report financial results, which could result in a loss of investor confidence and adversely affect the market price of our common stock.

We are required to establish and maintain internal control over financial reporting and disclosure controls and procedures. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles. Disclosure controls and procedures are processes designed to ensure that information required to be disclosed is communicated to management and reported in a timely manner. We cannot be certain that we will successfully maintain adequate control over our financial reporting and disclosure controls and procedures. See "Controls and Procedures" in Part II, Item 9A, of this Annual Report on Form 10-K for a discussion of the material weakness in our internal control over financial reporting that management has concluded exist in connection with preparing our financial statements for the year ended December 31, 2023. Deficiencies, including any material weakness, in our internal control over financial reporting that may occur could result in misstatements or restatements of our financial statements or a decline in the price of our securities. In addition, to the extent we make additional significant acquisitions, our internal controls will become more complex and may require significantly more resources to ensure that our disclosure controls and procedures remain effective. Acquisitions can pose challenges in implementing the required processes, procedures and controls in the operations of the companies that we acquire. Companies that are acquired by us may not have disclosure controls and procedures or internal control over financial reporting that are as thorough or effective as those required by the securities laws that currently apply to us.
12

SUN COMMUNITIES, INC.
Moreover, the existence of any material weakness or significant deficiency in our internal controls and procedures has required and would require management to devote significant time and incur significant expense to remediate any such material weaknesses or significant deficiencies and management may not be able to remediate any such material weaknesses or significant deficiencies in a timely manner. If we cannot provide reliable financial reports, our reputation and operating results could be materially adversely affected, which could also cause investors to lose confidence in our reported financial information, which in turn could result in a reduction in the trading price of our common stock.

We have concluded that certain of our previously issued interim unaudited consolidated financial statements should not be relied upon and have restated certain of our previously issued financial statements, which was time-consuming and expensive and could expose us to additional risks that could have a negative effect on us.

As discussed in the Explanatory Note, we determined to restate our unaudited consolidated financial statements as of March 31, 2023, June 30, 2023 and September 30, 2023, and that such interim unaudited financial statements should no longer be relied upon. As a result, we have incurred unanticipated costs for accounting and legal fees related to this restatement, and have become subject to a number of additional risks and uncertainties, which may affect investor confidence in the accuracy of our financial disclosures and may raise reputational issues for our business. We expect to continue to face many of the risks and challenges related to the restatement, including the following:

we may fail to remediate material weaknesses in our internal control over financial reporting and other material weaknesses may be identified in the future, which would adversely affect the accuracy and timing of our financial reporting;
the processes undertaken to affect the restatement may not have been adequate to identify and correct all errors in our historical financial statements and, as a result, we may discover additional errors and our financial statements remain subject to the risk of future restatement;
the incurrence of restatement-related expenses; and
diversion of management and other human resources attention from the operation of our business.

We cannot assure that all of the risks and challenges described above will be eliminated and that lost business opportunities can be recaptured or that general reputational harm will not persist. If one or more of the foregoing risks or challenges persist, there may be a material adverse effect on our business, financial condition, results of operations, and cash flows.

We have been and may in the future be required to write down intangible assets, including goodwill, due to impairment, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We have in the past and may in the future be required to write down intangible assets, including goodwill, due to impairment, which would reduce earnings. We periodically calculate the fair value of our intangible assets to test for impairment. This calculation may be affected by several factors, including changes in general economic conditions, including inflation, deflation and energy costs; changes in foreign currency exchange rates; our rental rates and occupancy levels; increases in interest rates and operating costs, including insurance premiums and real estate taxes; the effects of natural disasters; and competitive market forces. Certain events can also trigger an immediate review of goodwill and intangible assets. If the carrying value of our intangible assets exceeds its fair value, the goodwill and other intangible assets are considered impaired, which would result in impairment losses and could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Refer to Note 1, "Significant Accounting Policies," Note 6, "Goodwill and Other Intangible Assets," and Note 22, "Quarterly Financial Data (Unaudited and Restated)", in our accompanying Consolidated Financial Statements, "Controls and Procedures" in Part II, Item 9A, and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of this Annual Report for information on impairments to the goodwill for our Park Holidays portfolio in the UK that we recognized at each of March 31, 2023, June 30, 2023 and September 30, 2023.

MATERIAL RISKS RELATING TO OUR MH, RV AND MARINA BUSINESSES

General economic conditions and the concentration of our MH, RV and marina properties in certain geographic areas may affect our ability to generate revenue.

The market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets, may significantly affect occupancy or rental rates. Occupancy and rental rates, in turn, may significantly affect our revenues, and if our properties do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flows and ability to pay or refinance our debt obligations could be adversely affected.
13

SUN COMMUNITIES, INC.
As of December 31, 2023, 150 of our MH and RV communities and marinas, representing 21.8% of developed sites, are located in Florida; 92 communities, representing 16.5% of developed sites, are located in Michigan; 55 communities, representing 9.4% of developed sites, are located in the UK; 48 communities, representing 6.4% of developed sites, are located in California; and 32 communities, representing 5.7% of developed sites, are located in Texas. As of December 31, 2023, we have revenue concentrations of marinas in Florida, Rhode Island and Georgia of approximately 32.8%, 8.7% and 8.0%, respectively. As a result of the geographic concentration of our MH and RV communities in Florida, Michigan, the UK, California and Texas, and of our marinas in Florida, Rhode Island and Georgia, we are exposed to the risks of downturns in local economies or other local real estate market conditions which could adversely affect occupancy rates, rental rates and property values in these markets.

Our revenue would also be adversely affected if tenants and members were unable to pay rent or if sites were unable to be rented on favorable terms. If we were unable to promptly relet or renew the leases for a significant number of the sites, or if the rental rates upon such renewal or reletting were significantly lower than expected rates, then our business and results of operations could be adversely affected. In addition, certain expenditures associated with each property (such as real estate taxes and maintenance costs) generally are not reduced when circumstances cause a reduction in income from the property. Furthermore, real estate investments are relatively illiquid and, therefore, will tend to limit our ability to vary our portfolio promptly in response to changes in economic or other conditions.

The following factors, among others, may adversely affect the revenue
