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 our Park Holidays subsidiaries and the other entities through which we operate our business in the United Kingdom ("UK") are referred to herein as the "Company," "SUI," "us," "we," 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."), Canada, and the UK (marinas and, together with MH and RV, the "properties"). We self-administer, self-manage, 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 operating, acquiring, developing, and expanding MH and RV communities since 1975, marinas since 2020, and communities in the UK since 2022.

For our MH and RV businesses, we lease individual parcels of land, or 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. Our RV communities are designed to offer affordable vacation opportunities to individuals and families complemented by a diverse selection of high-quality amenities. Through SHS, a taxable REIT subsidiary, we market, sell, and lease new and pre-owned homes to current and future residents in our MH and RV communities. The operations of SHS support and enhance our occupancy levels, property performance, and cash flows.

The majority of our marinas are concentrated in coastal regions and 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.

In the UK, our communities are referred to as "holiday parks" and are located predominantly at irreplaceable seaside destinations in the south of England. We sell homes to holiday homeowners who lease a pitch at one of our properties through a site fee license arrangement. In addition, we sell new and pre-owned homes to current and prospective customers. We also provide vacation opportunities to individuals and families complemented by high-quality amenities.

As of December 31, 2024, we owned and operated, directly or indirectly, or had an interest in, a portfolio of 645 developed properties located in the U.S., Canada, and the UK, including 288 MH communities, 166 RV communities, 138 marinas, and 53 UK communities. As of December 31, 2024, the properties contained an aggregate of 225,150 developed sites comprised of 97,430 developed MH sites, 32,100 annual RV sites (inclusive of both annual and seasonal usage rights), 24,830 transient RV sites, 17,690 UK annual sites, 4,340 UK transient RV sites, and 48,760 wet slips and dry storage spaces. Additionally, we own or control land to support developing and expanding nearly 16,570 additional MH and RV sites suitable for development.

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 6,590 full and part time employees as of December 31, 2024.

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.

SAFE HARBOR SALE

On February 24, 2025, we entered into a purchase agreement (the "Purchase Agreement") to sell Safe Harbor for an aggregate purchase price of approximately $5.65 billion, subject to certain adjustments (the "Safe Harbor Sale"). While the Safe Harbor Sale is anticipated to close in the second quarter of 2025, it may not be completed on the anticipated timeline, or at all. The closing of the Safe Harbor Sale is subject to the satisfaction or waiver of certain customary conditions to closing, including: (i) all applicable waiting periods (and any extensions thereof) required under the HSR Act shall have expired or been terminated, and (ii) the absence of any law, order, injunction or ruling issued by a court or other governmental authority permanently restraining, enjoining or making illegal the Safe Harbor Sale. Each party's obligation to consummate the Safe Harbor Sale is also conditioned upon the accuracy of the other party's representations and warranties (generally subject, other than for certain fundamental representations and warranties, to a material adverse effect standard) and the other party's having performed in all material respects its obligations under the Purchase Agreement. The transfer of subsidiaries owning approximately 25 of Safe Harbor's properties (the "Delayed Consent Subsidiaries") with an aggregate agreed value of up to approximately $769 million is further subject to the receipt of certain third-party consents and the Delayed Consent Subsidiaries therefore may be transferred in one or more subsequent closings, and is subject to certain conditions to closing.

The Purchase Agreement also contains certain customary termination rights for the parties, including mutual consent of the parties or, subject to certain conditions, by either us or the buyer, if the closing of the Safe Harbor Sale has not occurred prior to August 24, 2025, or if a governmental authority has issued a final, non-appealable order permanently restraining, enjoining, preventing, or otherwise prohibiting, or making illegal, the consummation of the Safe Harbor Sale. The Purchase Agreement may also be terminated by either party if, subject to certain conditions, the other party is in breach of the Purchase Agreement and such breach would prevent the satisfaction of its closing conditions and is incapable of or has not been cured within a given time period, or if a party fails to close following the satisfaction of the closing conditions, subject to certain limitations. In the following circumstances further described in the Purchase Agreement, in connection with the termination of the Purchase Agreement, the buyer will be required to pay us a termination fee (the "Buyer Termination Fee") of $565 million upon termination of the Purchase Agreement, which circumstances are (i) if we terminate the Purchase Agreement as a result of an uncured material breach of the Purchase Agreement by the buyer, or (ii) as a result of the buyer's failure to close when otherwise obligated pursuant to the Purchase Agreement.

Refer to Part I, Item 1A, "Risk Factors – Risks Related to the Safe Harbor Sale" and Note 20, "Subsequent Events," in our accompanying Consolidated Financial Statements.

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.

REAL PROPERTY OPERATIONS AND COMPETITION

MH and RV Segments

An MH community is a residential subdivision with sites for the placement of manufactured homes, related improvements, and amenities. Our MH communities are designed to offer affordable housing to individuals and families, while also providing certain 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, swimming pools, 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 amenities such as restaurants, golf courses, swimming pools, water parks, tennis courts, fitness centers, planned activities, and spacious social facilities. We operate the majority of our RV communities under the "Sun Outdoors" brand, which we believe supports our competitive advantage in the outdoor market. Sun Outdoors offers RV sites, vacation rentals, and tent camping with world-class amenities, primarily in the U.S.

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 contractual ground lease arrangements. 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.

We compete with other 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.

Marina Segment

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 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 marinas in the U.S. Through the marketing and leasing of wet slips and dry storage spaces, we have approximately 49,000 members throughout the marina network as of December 31, 2024.

UK Segment

In the UK, we sell homes to holiday homeowners who lease a pitch at one of our properties through a site fee license arrangement. In addition, we sell new and pre-owned homes to current and prospective customers. We also provide vacation opportunities to individuals and families complemented by high-quality amenities. The holiday park industry in the UK is highly fragmented.

SUN COMMUNITIES, INC.
PROPERTY MANAGEMENT

Our property management strategy emphasizes intensive, detail-oriented, hands-on management by dedicated, on-site MH, RV, and UK community managers as well as 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, 2024, of our 6,590 employees, 1,286 were located on-site as property managers, and of those, 99.4% were full-time employees. We also selectively utilize third-party managers to oversee the operations at certain of our RV properties to further enhance the efficiency of our property management strategy. As of December 31, 2024, approximately 49 of our RV properties were managed by third-party managers.

Our MH and RV property managers in the U.S. and Canada are overseen by our Chief Operating Officer ("COO"), and a team of Senior Vice Presidents, Divisional Vice Presidents, and Regional Vice Presidents. Each Regional Vice President typically oversees nine to 15 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.

Our marina business is overseen by a Chief Executive Officer ("CEO") of Safe Harbor and a team consisting of Executive Vice Presidents of Operations, Senior Vice Presidents of Operations, and Regional Vice Presidents who are responsible for regular marina inspections and oversight of operations.

Our UK business is overseen by the CEO of Park Holidays, a COO, and several Regional Operations Directors who are responsible for all on-site operations in the UK.

HOME SALES AND RENTALS

We market, sell, and lease new and pre-owned homes to current and future residents in our MH and RV communities through SHS in the U.S., and to current and future holiday homeowners through our subsidiaries in the UK. Because tenants and holiday homeowners often purchase a home already on-site within a community, the services SHS and our UK subsidiaries 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, 2024, SHS's portfolio consists of over 11,210 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 2024, we received over 36,600 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 in the U.S. and other holiday park owners in the UK.

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, 2024, on average less than 1.0% of the homes in our MH communities have been removed by their owners and 5.7% of the homes have been sold by their owners to a new owner who then assumes rental obligations as a community resident. During the three years ended December 31, 2024, on average, our residents remain in our communities for approximately 19 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 7.5 years.

ACQUISITION AND DISPOSITION STRATEGY

From 2010 through 2022, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV, marina, and UK properties. With the benefit of our expanded portfolio, beginning in 2023, we shifted our strategy toward optimizing the value of our existing businesses through achieving strong rental rate growth and operating efficiencies, while still pursuing select new acquisition and expansion opportunities. This strategy continued in 2024 as we determined to divest non-strategic assets and focus on simplification of our operations and capital structure.

During the year ended December 31, 2024, we sold 10 MH properties, 13 RV properties, two UK properties, and three MH development properties with an aggregate of 6,526 sites for a gross sale price of approximately $476.8 million, and received total cash consideration of approximately $326.7 million, net of settlement of the associated mortgage debt of $93.5 million. We also selectively acquired three marinas and three marina expansion assets with an aggregate of 925 wet slips and dry storage spaces for an aggregate purchase price of approximately $63.8 million.

REGULATIONS AND INSURANCE

General

MH, RV, marina, and UK 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 employee retention and talent development practices. We are committed to building a culture that inspires and supports the growth of our employees, serves our communities, and shapes a more competitive business.

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.

We believe we are a stronger organization when our workforce represents a broad range of ideas and experiences. As of December 31, 2024, 39% of our employees were female, 26% of our employees (excluding those in Canada and the UK) were racially or ethnically diverse, and 43% of our employees were aged 50 years and older, with approximately 10% being aged 60 years and older.

Training and Resources

We offer training and resources on cybersecurity, fair housing and anti-discrimination laws and regulation, sexual harassment and discrimination, and leadership development. We are committed to providing a total compensation package that is market-based, performance driven, fair, and internally equitable. We conduct ongoing pay equity analyses to ensure that our employees are compensated fairly. Our goal is to be competitive both within the general employment market as well as with our competitors in the real estate industry.

Our Code of Conduct and Business Ethics is grounded in our commitment to do the right thing. It serves as the foundation for our approach to ethics and compliance. Our anti-corruption compliance program is focused on conducting business in a fair, ethical, and legal manner. We do not tolerate harassing, discriminatory or retaliatory conduct, as such conduct is inconsistent with our policies, practices, and philosophy.

We actively seek opportunities to minimize health, safety, and environmental risks to our team members, residents, and customers we serve in our communities by utilizing safe operating procedures in compliance with safety and health laws, providing ongoing role appropriate training, conducting regular inspections and reviews, and providing the appropriate tools and safeguards for accident prevention and risk management.

•If we fail to qualify as a REIT, among other things, our taxable income would be subject to federal income tax at a regular corporate rate.
•The Operating Partnership could be classified as a "publicly traded partnership" which would subject it to taxation as a corporation and lead to substantial tax liabilities.
•Compliance with the complex requirements and tests that are applied to REITs may limit our operational flexibility.

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 SAFE HARBOR SALE

The Safe Harbor Sale may not be completed on the anticipated timeline or at all, which could adversely affect the Company's business plans.

On February 24, 2025, we entered into the Purchase Agreement to sell Safe Harbor for an aggregate purchase price of approximately $5.65 billion, subject to certain adjustments. The closing of the Safe Harbor Sale is subject to the satisfaction or waiver of certain customary conditions to closing, including: (i) all applicable waiting periods (and any extensions thereof) required under the HSR Act shall have expired or been terminated, and (ii) the absence of any law, order, injunction or ruling issued by a court or other governmental authority permanently restraining, enjoining, or making illegal the Safe Harbor Sale. Each party's obligation to consummate the Safe Harbor Sale is also conditioned upon the accuracy of the other party's representations and warranties (generally subject, other than for certain fundamental representations and warranties, to a material adverse effect standard) and the other party's having performed in all material respects its obligations under the Purchase Agreement. The transfer of the Delayed Consent Subsidiaries is further subject to the receipt of certain third-party consents and the Delayed Consent Subsidiaries therefore may be transferred in one or more subsequent closings, and is subject to certain conditions to closing.


11
SUN COMMUNITIES, INC.
The Purchase Agreement also contains certain customary termination rights for the parties, including mutual consent of the parties or, subject to certain conditions, by either us or the buyer, if the closing of the Safe Harbor Sale has not occurred prior to August 24, 2025, or if a governmental authority has issued a final, non-appealable order permanently restraining, enjoining, preventing, or otherwise prohibiting, or making illegal the consummation of the Safe Harbor Sale. The Purchase Agreement may also be terminated by either party if, subject to certain conditions, the other party is in breach of the Purchase Agreement and such breach would prevent the satisfaction of its closing conditions and is incapable of or has not been cured within a given time period, or if a party fails to close following the satisfaction of the closing conditions, subject to certain limitations. In the following circumstances further described in the Purchase Agreement, in connection with the termination of the Purchase Agreement, the buyer will be required to pay us the Buyer Termination Fee of $565 million upon termination of the Purchase Agreement, which circumstances are (i) if we terminate the Purchase Agreement as a result of an uncured material breach of the Purchase Agreement by the buyer, or (ii) as a result of the buyer's failure to close when otherwise obligated pursuant to the Purchase Agreement.

If the closing conditions to the initial closing are not satisfied or waived, or if the Purchase Agreement is terminated in accordance with its terms, the Safe Harbor Sale will not be consummated. Similarly, if the closing conditions to the transfer of any Delayed Consent Subsidiary, including receipt of the required consents, are not satisfied, the sale of such Delayed Consent Subsidiary may not be consummated. Even if the closing conditions for the initial closing or subsequent closings are ultimately satisfied, their satisfaction may take longer than expected, which could delay the completion of the Safe Harbor sale or the sale of one or more of the Delayed Consent Subsidiaries. Any such delay or failure to complete the Safe Harbor Sale or the sale of the Delayed Consent Subsidiaries could materially and adversely affect the Company's business and the price of our common stock, and could require the Company to seek alternative strategies for Safe Harbor. We also cannot provide any assurances that the conditions required to be satisfied to receive the Buyer Termination Fee will be satisfied upon a termination of the Purchase Agreement.

The pendency of the Safe Harbor Sale could adversely affect the business and operations of the Company and / or Safe Harbor.

In connection with the pending Safe Harbor Sale, some clients of Safe Harbor may delay or defer decisions, which could adversely affect the revenues, earnings, funds from operations, cash flows and expenses of Safe Harbor and the Company, regardless of whether the Safe Harbor Sale is completed. Similarly, current and prospective employees of Safe Harbor may experience uncertainty about their future roles, which may adversely affect the Company's ability to attract and retain key personnel during the pendency of the Safe Harbor Sale. In addition, due to operating covenants in the Purchase Agreement, Safe Harbor may be unable (without the other party's prior written consent), during the pendency of the Safe Harbor Sale, to pursue strategic transactions, undertake certain significant financing transactions and otherwise pursue other actions, even if such actions would prove beneficial, which could have an adverse effect on the Company's business and financial condition.

We will have broad discretion in the use of proceeds from the Safe Harbor Sale.

We anticipate using the net proceeds from the Safe Harbor sale to support a combination of debt paydown, distributions to shareholders, and reinvestment in our core businesses. Our Board and management will have broad discretion in the application of the net proceeds, and shareholders will be relying on the judgment of our Board and management regarding the use of these proceeds. The Company may ultimately use the proceeds for different purposes than what is currently intended. The use of those proceeds, including any distributions that may be made, may have adverse tax consequences, both for us and our shareholders, and, in certain cases, if any distributions are made, shareholders may recognize taxable income in excess of the cash they receive. The tax consequences of any such distributions will vary depending on each shareholder's particular circumstances, and shareholders are urged to consult their own tax advisors regarding the specific tax consequences applicable to them. In addition, the Company's failure to apply these funds effectively could have an adverse effect on its business and financial condition.

We may be unable to realize the anticipated benefits of the Safe Harbor Sale, once completed, or to do so within the anticipated time frame.

A number of risks and challenges may arise from the Safe Harbor Sale that may cause us to be unable to realize the anticipated benefits therefrom, including, but not limited to, purchase price adjustments; unexpected costs, charges or expenses; diversion of management's attention; unexpected operational inefficiencies; adverse tax consequences for us; the duration of time to closing the Safe Harbor Sale (and / or the subsequent closings contemplated thereby); the potential retention of certain properties and other matters. We cannot predict the scope or nature of these risks, or the timeframe in which we will be able to realize the anticipated benefits of the Safe Harbor Sale. These risks could have an adverse effect on the Company's business and financial condition, as well as the Company's ability to accurately predict future performance.

Our actual business and operating results may differ materially from our guidance or other forward-looking statements.

Guidance and other forward-looking statements are necessarily speculative in nature, and it can be expected that some or all of the assumptions of such information furnished by us will not materialize or will vary significantly from our actual results. Our guidance and forward-looking statements are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to business, economic, regulatory and competitive uncertainties, and contingencies, many of which are beyond our control, and are based upon specific assumptions with respect to future business decisions, some of which will change, and are solely based on the facts and circumstances presented at the time such information is provided. The likelihood of differences between our guidance and other forward-looking statements and the actual results from our business and operations are significantly higher during the pendency of a significant transaction, such as the Safe Harbor Sale, for which there are many assumptions and uncertainties that could impact our business and operating results, including with respect to certainty, timing, proceeds (and the uses thereof), and other factors, including those described elsewhere in this Annual Report on Form 10-K. Refer to Part I, Item 1, "Business - Cautionary Statement Regarding Forward-Looking Statements."

MATERIAL RISKS RELATING TO OUR MH, RV, MARINA, AND UK BUSINESSES

General economic conditions and the concentration of our MH, RV, Marina, and UK 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.

As of December 31, 2024, 148 of our MH, RV, and UK communities and marinas, representing 22.4% of developed sites, are located in Florida; 92 communities, representing 16.6% of developed sites, are located in Michigan; 53 communities, representing 9.8% of developed sites, are located in the UK; 49 communities, representing 6.8% of developed sites, are located in California; and 32 communities, representing 5.8% of developed sites, are located in Texas. As of December 31, 2024, we have revenue concentrations of marinas in Florida, Rhode Island and Georgia of approximately 31.9%, 8.9% and 8.0%, respectively. As a result of the geographic concentration of our MH, RV, and UK 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 revenues generated by our properties:

•the international, national and local economic climate which may be adversely impacted by, among other factors, plant closings, industry slowdowns and inflation;
•local real estate market conditions such as the oversupply of MH or RV sites or a reduction in demand for MH or RV sites in an area, and an oversupply of, or a reduced demand for, manufactured homes;
•increased operating costs, including insurance premiums, real estate taxes and utilities;
•competition from other available MH and RV communities and alternative forms of housing (such as apartment buildings and site-built single-family homes), and other marinas;
•a decrease in the number of people interested in the RV lifestyle or boating;
•outbreaks of disease and related restrictions on business operations;
•changes in foreign currency exchange rates, including between the U.S. dollar and each of the Canadian dollar, Australian dollar and pound sterling;
•the number of repossessed homes in a particular market;

13
SUN COMMUNITIES, INC.
•the difficulty facing potential purchasers in obtaining affordable financing as a result of heightened lending criteria;
•an increase or decrease in the rate of manufactured home repossessions which provide aggressively priced competition to new manufactured home sales;
•the lack of an established MH dealer network;
•the housing rental market which may limit the extent to which rents may be increased to meet increased expenses without decreasing occupancy rates;
•the perceptions by prospective tenants of the safety, convenience and attractiveness of our MH properties and the neighborhoods where they are located;
•zoning or other environmental regulatory restrictions;
•our ability to effectively manage, maintain and insure our properties; and
•the enactment of rent control laws or laws taxing the owners of manufactured homes.

We may not be able to integrate or finance our expansion and development activities.

We build and develop new MH and RV communities and marinas and we expand existing communities and marinas. Our construction and development pipeline may be exposed to the following risks which are in addition to those risks associated with the ownership and operation of established MH and RV communities and marinas:

•we may not be able to obtain financing with favorable terms for development which may make us unable to proceed with the development;
•we may be unable to obtain, or face delays in obtaining, necessary zoning, building and other governmental permits and authorizations, which could result in increased costs and delays, and even require us to abandon development of the property entirely if we are unable to obtain such permits or authorizations;
•we may abandon development opportunities that we have already begun to explore and as a result we may not recover expenses already incurred in connection with exploring such development opportunities;
•we may be unable to complete construction and lease-up of a property on schedule resulting in increased debt service expense and construction costs;
•we may incur construction and development costs for a property which exceed our original estimates due to increased materials, labor or other costs, which could make completing the development uneconomical and we may not be able to increase rents to compensate for the increase in development costs which may impact our profitability;
•we may be unable to secure long-term financing on completion of development resulting in increased debt service and lower profitability;
•occupancy rates and rents at a newly developed property may fluctuate depending on several factors, including market and economic conditions, which may result in the property not being profitable; and
•climate change may cause new marina developments to be paused or restricted.

If any of the above risks occur, our business and results of operations could be adversely affected.

Competition affects occupancy levels and rents, which could adversely affect our revenues.

The MH, RV, and marina industries are highly-fragmented. There are many international, national and regional competitors in the markets we currently serve and in new markets that we may enter. Our properties are located in developed areas that include other MH or RV communities, and marinas. The number of competitive communities and marinas in a particular area could have a material adverse effect on our ability to lease sites and increase rents charged at our properties or at any newly acquired properties. We may be competing with others with greater resources. In addition, other forms of multi-family residential properties, such as private and federally funded or assisted multi-family housing projects and single-family housing, provide housing alternatives to potential tenants of MH or RV communities.

SUN COMMUNITIES, INC.
The cyclical and seasonal nature of the RV, Marina, and UK segments may lead to fluctuations in our operating results.

The RV, Marina, and UK segments can experience cycles of growth and downturn due to seasonality patterns. Results of operations in any one period may not be indicative of results in future periods. In the RV segment, certain properties maintain higher occupancy during the summer months, while other properties maintain higher occupancy during the winter months. The RV segment typically shows a decline in demand over the winter months, yet usually produces higher growth in the spring and summer months due to higher use by vacationers. In the Marina segment, demand for wet slip storage increases during the summer months as customers contract for the summer boating season, which also drives non-storage revenue streams such as service, fuel and on-premise restaurants or convenience storage. Demand for dry storage increases during the winter season as seasonal weather patterns require boat owners to store their vessels on dry docks or within covered racks. In the UK segment, vacation rental sites generally produce higher revenues between March and October. Our results on a quarterly basis can fluctuate due to this cyclicality and seasonality.

We may not be able to integrate or finance our acquisitions and our acquisitions may not perform as expected.

We have acquired and intend to continue to selectively acquire MH, RV, and marina properties. Our acquisition activities and their success are subject to the following risks:

•we may be unable to acquire a desired property because of competition from other well-capitalized real estate investors, including both publicly traded REITs and institutional investment funds;
•even if we enter into an acquisition agreement for a property, it is usually subject to customary conditions to closing, including completion of due diligence investigations to our satisfaction, which may not be satisfied;
•even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price;
•we may be unable to finance acquisitions on favorable terms;
•acquired properties may fail to perform as expected;
•acquired properties may be located in new markets where we face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area, and unfamiliarity with local governmental and permitting procedures; and
•we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations.

If any of the above risks occur, our business and results of operations could be adversely affected.

In addition, we may acquire properties subject to liabilities and we may be left with no, or limited, recourse, with respect to unknown liabilities. As a result, we may have to pay substantial sums to settle any liabilities asserted against us based upon ownership of newly acquired properties, which could adversely affect our cash flows.

Investments through joint ventures involve risks not present in properties in which we are the sole owner.

We have invested and may continue to invest as a joint venture partner in joint ventures. These investments involve risks, including, but not limited to, the possibility the other joint venture partner may have business goals which are inconsistent with ours, possess the ability to take or force action or withhold consent contrary to our requests, fail to provide capital or fulfill its obligations, or become insolvent and require us to assume and fulfill the joint venture's financial obligations. Conflicts arising between us and our joint venture partners may be difficult to manage or resolve and it could be difficult to manage or otherwise monitor the existing business arrangements. We and our joint venture partners may each have the right to initiate a buy-sell arrangement, which could cause us to sell our interest, or acquire a joint venture partner's interest, at a time when we otherwise would not have entered into such a transaction. Each joint venture agreement is individually negotiated, and our ability to operate, finance or dispose of a property in our sole discretion may be limited to varying degrees depending on the terms of the applicable joint venture agreement.

Many of our properties are located in areas that experience extreme weather conditions and natural disasters and climate change may adversely affect our business.

Extreme weather or weather-related conditions and other natural disasters, including hurricanes, flash floods, sea-level rise, droughts, tornadoes, wildfires or earthquakes, may interrupt our operations, damage our properties and reduce the number of customers who utilize our properties in the affected areas. Many of our properties are on coastlines that are subject to hurricane seasons, flash flooding and sea level rise; in areas adversely affected by wildfires, such as the western U.S.; and in earthquake-prone areas, such as the West Coast. If there are prolonged disruptions at our properties due to extreme weather or natural disasters, our results of operations and financial condition could be materially adversely affected.

While we maintain insurance coverage that may cover certain of the costs and loss of revenue associated with the effect of extreme weather and natural disasters at our properties, our coverage is subject to deductibles and limits on maximum benefits. We cannot assure you that we will be able to fully collect, if at all, on any claims resulting from extreme weather or natural disasters.

If any of our properties are damaged or if their operations are disrupted as a result of extreme weather or natural disasters, or if extreme weather or natural disasters adversely impact general economic or other conditions in the areas in which our properties are located or from which they draw their tenants and customers, our business, financial condition and results of operations could be materially adversely affected.

Significant changes in the climate could exacerbate extreme weather conditions or natural disasters that may occur in areas where our properties are located, all of which may result in additional physical damage to, or a decrease in demand for, properties located in these areas or affected by these conditions. If the impact of climate change is material in nature, including significant property damage to or destruction of our properties, or occurs for lengthy periods of time, our financial condition or results of operations may be adversely affected.

While they are unpredictable, the impacts of climate change may change residential migration and vacation trends, which could reduce demand for our properties. If the areas in which our properties are located become less desirable places to live or vacation, the value of our properties and their ability to generate revenue may be materially adversely affected.

In addition, changes in federal, state, local and foreign legislation and regulation based on concerns about climate change, as well as voluntary measures we take to combat climate change, could result in increased capital expenditures at our properties. For example, these could include expenditures to improve energy efficiency, improve resistance to inclement weather and provide for infrastructure improvement to support existing and emerging low-carbon technologies. These expenditures may not result in a corresponding increase in revenue, resulting in material adverse impacts to our financial results.

Marinas may not be readily adaptable to other uses.

Marinas are specific-use properties and may contain features or assets that have limited alternative uses. These properties may also have distinct operational functions that involve specific procedures and training. If the operations of any of our marinas become unprofitable due to industry competition, operational execution or otherwise, then it may not be feasible to operate the property for another use, and the value of certain features or assets used at the property, or the property itself, may be impaired. Should any of these events occur, our financial condition, results of operations and cash flows could be adversely impacted.

We may be unable to obtain, renew or maintain permits, licenses and approvals necessary for the operation of our Marinas.

The U.S. Army Corps of Engineers, the Coast Guard and other governmental bodies control much of the land located beneath and surrounding many of our marinas and lease such land to Safe Harbor under leases that typically range from five to 50 years. As a result, it is unlikely that we can obtain fee-simple title to the land on or near these marinas. If these governmental authorities terminate, fail to renew, or interpret in ways that are materially less favorable any of the permits, licenses and approvals necessary for the operation of these properties, then our financial condition, results of operations and cash flows could be adversely impacted.

Some marinas must be dredged from time to time to remove silt and mud that collect in harbor-areas in order to ensure that boat traffic can safely enter the harbor. Dredging and disposing of the dredged material can be very costly and require permits from various governmental authorities. If the permits necessary to dredge marinas or dispose of the dredged material cannot be timely obtained after the acquisition of a marina, or if dredging is not practical or is exceedingly expensive, the operations of such property would be materially and adversely affected.

SUN COMMUNITIES, INC.
We may incur liability under environmental laws arising from conditions at properties we acquire or operations at the properties we own and operate.

Under various federal, state, local and foreign laws, ordinances and regulations, an owner or operator of real estate is liable for the costs of removal or remediation of certain hazardous substances at, on, under, or in such property. Such hazardous substances may be used at or located on our properties, especially our marinas. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous substances. The presence of such substances, or the failure to properly remediate such substances, may adversely affect the owner's ability to sell or rent the property, to borrow using the property as collateral or to develop the property. Persons who arrange for the disposal or treatment of hazardous substances also may be liable for the costs of removal or remediation of such substances at a disposal or treatment facility owned or operated by another person. In addition, certain environmental laws impose liability for the management and disposal of asbestos-containing materials and for the release of such materials into the air. These laws may result in fines or penalties and may permit third parties to seek recovery from owners or operators of real properties for personal injury associated with asbestos-containing materials.

As the purchaser of properties we acquire, or in connection with the operation of properties we own or manage, we may be liable for removal or remediation costs, governmental fines and injuries to persons and property. When we arrange for the treatment or disposal of hazardous substances at landfills or other facilities owned by other persons, we may be liable for the removal or remediation costs at such facilities.

As part of our standard acquisition due diligence, we subject our properties to a Phase I or similar environmental assessment as well as limited compliance evaluations (which involve general inspections without soil sampling or ground water analysis) completed by independent environmental and engineering consultants. In some cases, where these evaluations have recommended further, invasive investigations, those have also been conducted. While these environmental evaluations have not revealed any significant environmental liability that would have a material adverse effect on our business, they cannot reflect conditions arising after the studies were completed. No assurances can be given that existing environmental studies reveal all environmental liabilities, that any prior owner or operator of a property or neighboring owner or operator did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist with respect to any one or more properties.

Moreover, we cannot be sure that future laws, ordinances or regulations will not impose any material environmental liability, or that the current environmental condition of our properties will not be affected by tenants and occupants of the properties, by the condition of land or operations in the vicinity of our properties (such as the presence of underground storage tanks), or by unrelated third parties. Environmental liabilities that we may incur could have an adverse effect on our financial condition, results of operations and cash flows.

We are subject to additional risks from our international investments.

We have significant ownership in the UK through our ownership of Park Holidays and other subsidiaries. Our investments in the UK and any other international investments we may acquire, subjects us to additional risks, including:

•the laws, rules and regulations applicable in such jurisdictions outside of the U.S., including those related to property ownership by foreign entities, consumer and data protection, privacy, network security, encryption, payments and restricting us from removing profits earned from activities within the country to the U.S. (i.e., nationalization of assets located within a country);
•complying with a wide variety of foreign laws;
•fluctuations in exchange rates between foreign currencies and the U.S. dollar, and exchange controls;
•limited experience with local business and cultural factors that differ from our usual standards and practices;
•changes in the availability, cost and terms of mortgage funds and other borrowings resulting from varying national economic policies or changes in interest rates;
•reliance on local management;
•challenges in establishing effective controls and procedures to regulate operations in different regions and to monitor and ensure compliance with applicable regulations, such as applicable laws related to corrupt practices, employment, licensing, construction, climate change or environmental compliance;
•unexpected changes in regulatory requirements, tax, tariffs, trade barriers and other laws within jurisdictions outside the U.S. or between the U.S. and such jurisdictions;
•potentially adverse tax consequences with respect to our properties;

17
SUN COMMUNITIES, INC.
•the impact of regional or country-specific business cycles and economic instability, including deterioration in political relations with the U.S., instability in, or further withdrawals from, the European Union or other international trade alliances or agreements;
•the impact of disruptions in global, regional or local supply chains, including disruptions occurring as a result of outbreaks of disease; and
•political instability, uncertainty over property rights, civil unrest, drug trafficking, political activism or the continuation or escalation of terrorist activities.

If we are unable to adequately address these risks, they could have a significant adverse effect on our operations.

We depend on Safe Harbor's management to operate our marina business.

Safe Harbor's operations are separate from our other operations. The successful operation of our marinas depends on our ability to retain key employees with experience in the marina business, including Baxter R. Underwood, who is the Chief Executive Officer of Safe Harbor. The loss of services of Mr. Underwood or other key employees could have a material adverse effect on our ability to operate Safe Harbor. Although Mr. Underwood has entered into an employment and non-competition agreement, upon certain events he will have the option to eliminate the non-competition covenant by foregoing certain compensation and other benefits. We do not currently maintain or contemplate obtaining any "key-man" life insurance on any of the key employees of Safe Harbor.

Public health crises, such as outbreaks of disease, could materially and adversely affect our financial condition, operating results and cash flows.

A public health crisis, such as the COVID-19 pandemic, could have material and adverse effects on our ability to successfully operate our business and on our financial condition. The government and societal responses to public health crises are highly uncertain and we cannot predict with confidence the impact a public health crisis would have on our operations and financial condition.

Rent control legislation may harm our ability to increase rents.

National, state and local rent control laws in certain jurisdictions may limit our ability to increase rents at our MH properties to recover increases in operating expenses and the costs of capital improvements. Enactment of such laws has been considered from time to time in other jurisdictions. Certain properties are located, and we may purchase additional properties, in markets that are either subject to rent control or in which rent-limiting legislation exists or may be enacted.

RISKS RELATED TO OUR DEBT FINANCINGS

Our significant amount of debt could limit our operational flexibility or otherwise adversely affect our financial condition, and we may incur more debt in the future.

We have a significant amount of debt. As of December 31, 2024, we had approximately $7.4 billion of total debt outstanding, consisting of approximately $3.3 billion in collateralized term loans and debt that is secured by mortgage liens on 137 of our properties, $2.7 billion of senior unsecured notes and $1.4 billion on our line of credit and other debt. Including the impact of hedge activity, as of December 31, 2024, approximately 91% of our total debt was fixed rate financing and approximately 9% of our total debt was floating rate financing. If we fail to meet our obligations under our secured debt, the lenders would be entitled to foreclose on all or some of the collateral securing such debt which could have a material adverse effect on us and our ability to make expected distributions, and could threaten our continued viability.

We are subject to the risks normally associated with debt financing, including the following risks:

•our cash flows may be insufficient to meet required debt payments, or we may need to dedicate a substantial portion of our cash flows to pay our debt rather than to other areas of our business;
•our existing debt may limit our operating flexibility due to financial and other restrictive covenants, including restrictions on incurring additional debt;
•it may be more difficult for us to obtain additional financing for our operations, working capital requirements, capital expenditures, debt service or other general requirements;
•increases in interest rates will increase the costs of our floating rate debt and make obtaining new debt more expensive;
•we may be more vulnerable in the event of adverse economic and industry conditions or a downturn in our business;

18
SUN COMMUNITIES, INC.
•we may be placed at a competitive disadvantage compared to our competitors that have less debt; and
•we may not be able to refinance at all or on favorable terms, as our debt matures.

If any of the above risks occurred, our financial condition and results of operations could be materially adversely affected.

Despite our current debt levels, we may incur substantially more debt in the future. If new debt is added to our current debt levels, an even greater portion of our cash flows will be needed to satisfy our debt service obligations. As a result, the related risks that we now face could intensify and increase the risk of a default on our debt.

Covenants in our credit agreements and senior unsecured note indentures could limit our flexibility and adversely affect our financial condition.

The terms of our financing agreements and other debt require us to comply with a number of customary financial and other covenants. These covenants may limit our flexibility in our operations, and breaches of these covenants could result in defaults under the instruments governing the applicable debt even if we have satisfied our payment obligations. Our financing agreements contain certain cross-default provisions that could be triggered in the event that we default on our other debt. These cross-default provisions may require us to repay or restructure our senior credit facility in addition to any mortgage or other debt that is in default. If our properties were foreclosed upon, or if we are unable to refinance our debt at maturity or meet our payment obligations, the amount of our distributable cash flows and our financial condition would be adversely affected.

Our senior credit facility contains various financial covenants including, but not limited to a maximum leverage ratio, a minimum fixed charge coverage ratio and a maximum secured leverage ratio. In addition to our senior credit facility, our senior unsecured notes also contain various covenants including an aggregate debt test, a secured debt test, a debt service test, and a maintenance of total unencumbered assets test. These covenants may restrict our ability to pursue certain business initiatives or certain transactions that might otherwise be advantageous. Furthermore, failure to meet certain of these financial covenants could cause an event of default under and / or accelerate some or all of such debt which could have a material adverse effect on us.

An increase in market interest rates could raise our interest costs on existing and future debt or adversely affect our stock price, and a decrease in interest rates may lead to additional competition for the acquisition of real estate or adversely affect our results of operations.

Our interest costs for any new debt and our current debt obligations may rise if interest rates increase. This increased cost could make the financing of any new acquisition more expensive, as well as lower our current period earnings. Rising interest rates could limit our ability to refinance existing debt when it matures or cause us to pay higher interest rates upon refinancing. In addition, an increase in interest rates could decrease our customers' access to credit, thereby decreasing the demand for manufactured homes and recreational vehicles. An increase in market interest rates may lead prospective purchasers of our common stock to expect a higher dividend yield, which could adversely affect the market price of our common stock. Decreases in interest rates may lead to additional competition for the acquisition of real estate due to a reduction in desirable alternative income-producing investments. Increased competition for the acquisition of real estate may lead to a decrease in the yields on real estate targeted for acquisition. In such circumstances, if we are not able to offset the decrease in yields by obtaining lower interest costs on our borrowings, our results of operations may be adversely affected.

Our hedging strategies may not be successful in mitigating our risks associated with interest rates and could reduce the overall returns on your investment.

We use various derivative financial instruments to provide a level of protection against interest rate risks, but no hedging strategy can protect us completely. These instruments involve risks, such as the risk that the counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes, that a court could rule that such agreements are not legally enforceable and that we may have to post collateral to enter into hedging transactions, which we may lose if we are unable to honor our obligations. These instruments may also generate income that may not be treated as qualifying REIT income for purposes of the REIT income tests. In addition, the nature and timing of hedging transactions may influence the effectiveness of our hedging strategies. Poorly designed strategies or improperly executed transactions could actually increase our risk and losses. Moreover, hedging strategies involve transaction and other costs. We cannot assure you that our hedging strategy and the derivatives that we use will adequately offset the risk of interest rate volatility or that our hedging transactions will not result in losses that may reduce the overall return on your investment.

A downgrade in our credit ratings could have material adverse effects on our business and financial condition.

We intend to manage our operations to maintain our investment grade credit ratings from S&P Global and Moody's. These ratings are based on a number of factors, which include assessments of our financial strength, liquidity, capital structure, asset quality, and sustainability of cash flows and earnings. Changes in these factors could lead to a downgrade of our ratings, resulting in an adverse impact on our cost and availability of capital, which could in turn have a material adverse impact on our financial condition, results of operations and liquidity.

TAX RISKS RELATED TO OUR STATUS AS A REIT

We may suffer adverse tax consequences and be unable to attract capital if we fail to qualify as a REIT.

We believe that since our taxable year ended December 31, 1994, we have been organized and operated, and intend to continue to operate, so as to qualify for taxation as a REIT under the Code. Although we believe that we have been and will continue to be organized and have operated and will continue to operate so as to qualify for taxation as a REIT, we cannot be assured that we have been or will continue to qualify as a REIT. Qualification as a REIT involves the satisfaction of numerous requirements on an annual and quarterly basis established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status.

If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates. Moreover, unless entitled to relief under certain statutory provisions, we also would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification was lost. This treatment would reduce our net earnings available for investment or distribution to shareholders because of the additional tax liability to us for the years involved. In addition, distributions to shareholders would no longer be required to be made.

Federal, state and foreign income tax laws governing REITs and related interpretations may change at any time, and any such legislative or other actions affecting REITs could have a negative effect on us.

Federal, state and foreign income tax laws governing REITs, or the administrative interpretations of those laws may be amended at any time. Changes to tax laws, regulations or administrative interpretations, which may be applied retroactively, could adversely affect us. We cannot predict whether, when, in what forms, or with what effective dates, the tax laws, regulations and administrative interpretations applicable to us may be changed. Such changes could significantly affect either our ability to qualify for taxation as a REIT or the income tax consequences to us.

We intend for the Operating Partnership to be taxed as a partnership, but we cannot guarantee that it will qualify.

We believe that the Operating Partnership has been organized as a partnership and will qualify for treatment as such under the Code. However, if the Operating Partnership is deemed to be a "publicly traded partnership," it will be treated as a corporation instead of a partnership for federal income tax purposes unless at least 90% of its income is qualifying income as defined in the Code. The income requirements applicable to REITs and the definition of "qualifying income" for purposes of this 90% test are similar in most respects. Qualifying income for the 90% test generally includes passive income, such as specified types of real property rents, dividends and interest. We believe that the Operating Partnership has and will continue to meet this 90% test, but we cannot guarantee that it has or will. If the Operating Partnership were to be taxed as a regular corporation, it would incur substantial tax liabilities, we would fail to qualify as a REIT for federal income tax purposes and our ability to raise additional capital could be significantly impaired.

Partnership tax audit rules could have a material adverse effect on us.

Under the rules applicable to U.S. federal income tax audits of partnerships, subject to certain exceptions, any audit adjustment to items of income, gain, loss, deduction or credit of a partnership (and a partner's allocable share thereof) is determined, and taxes, interest, and penalties attributable thereto are assessed and collected, at the partnership level. Unless the partnership makes an election or takes certain steps to require the partners to pay their tax on their allocable shares of the adjustment, it is possible that partnerships in which we directly or indirectly invest, including the Operating Partnership, would be required to pay additional taxes, interest and penalties as a result of an audit adjustment. We, as a direct or indirect partner of the Operating Partnership and other partnerships, could be required to bear the economic burden of those taxes, interest and penalties even though the Company, as a REIT, may not otherwise have been required to pay additional corporate-level tax. These rules are significant for collecting tax in partnership audits and there can be no assurance that these rules will not have a material adverse effect on us.

SUN COMMUNITIES, INC.
Our ability to accumulate cash may be restricted due to certain REIT distribution requirements.

In order to qualify as a REIT, we must distribute to our shareholders at least 90% of our REIT taxable income (calculated without any deduction for dividends paid and excluding net capital gain) and to avoid federal income taxation, our distributions must not be less than 100% of our REIT taxable income, including capital gains. As a result of the distribution requirements, we do not expect to accumulate significant amounts of cash. Accordingly, these distributions could significantly reduce the cash available to us in subsequent periods to fund our operations and future growth.

Our taxable REIT subsidiaries, or TRSs, are subject to special rules that may result in increased taxes.

As a REIT, we must pay a 100% penalty tax on certain payments that we receive if the economic arrangements between us and any of our TRSs are not comparable to similar arrangements between unrelated parties. The Internal Revenue Service may successfully assert that the economic arrangements of any of our inter-company transactions are not comparable to similar arrangements between unrelated parties. This would result in unexpected tax liability which would adversely affect our cash flows.

Dividends payable by REITs do not qualify for the reduced tax rates applicable to certain dividends.

The maximum federal tax rate for certain qualified dividends payable to domestic shareholders that are individuals, trusts and estates is 20%. Dividends payable by REITs, however, are generally not eligible for this reduced rate, although the Tax Cut and Jobs Act permits a 20% deduction equal to the amount of qualifying REIT dividends received, thus bringing the maximum federal tax rate on qualifying REIT dividends to 29.6%. While this rule does not adversely affect the taxation of REITs or dividends paid by REITs, the more favorable rates applicable to regular qualified corporate dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less competitive than investments in stock of non-REIT corporations that pay dividends, which could adversely affect the comparative value of the stock of REITs, including our common stock and any preferred stock. The 20% deduction on REIT dividends is scheduled to expire on January 1, 2026, absent further extension or amendment of the statute.

Prospective investors should consult their own tax advisors regarding the effect of this change on their effective tax rate with respect to REIT dividends.

Complying with REIT requirements may cause us to forego otherwise attractive opportunities.

To remain qualified as a REIT for federal income tax purposes, we must continually satisfy requirements and tests under the tax law concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our shareholders and the ownership of our stock. In order to meet these tests, we may be required to forego or limit attractive business or investment opportunities and distribute all of our net earnings rather than invest in attractive opportunities or hold larger liquid reserves. Therefore, compliance with the REIT requirements may hinder our ability to operate solely to maximize profits.

RISKS RELATED TO OUR STRUCTURE

Certain provisions in our governing documents may make it difficult for a third-party to acquire us.

9.8% Ownership Limit. In order to qualify and maintain our qualification as a REIT, not more than 50% of the outstanding shares of our capital stock may be owned, directly or indirectly, by five or fewer individuals. Thus, ownership of more than 9.8%, in number of shares or value, of the issued and outstanding shares of our capital stock by any single shareholder has been restricted, with certain exceptions, for the purpose of maintaining our qualification as a REIT under the Code. Such restrictions in our charter do not apply to Milton M. Shiffman, Gary A. Shiffman and Robert B. Bayer; trustees, personal representatives and agents to the extent acting for them or their respective estates; or certain of their respective relatives.

The 9.8% ownership limit, as well as our ability to issue additional shares of common stock or shares of other stock (which may have rights and preferences over the common stock), may discourage a change of control of the Company and may also: (a) deter tender offers for the common stock, which offers may be advantageous to shareholders; and (b) limit the opportunity for shareholders to receive a premium for their common stock that might otherwise exist if an investor were attempting to assemble a block of common stock in excess of 9.8% of our outstanding shares or otherwise effect a change of control of the Company.


21
SUN COMMUNITIES, INC.
Preferred Stock. Our charter authorizes the Board of Directors to issue up to 20,000,000 shares of preferred stock, none of which is currently outstanding, and to establish the preferences and rights (including the right to vote and the right to convert into shares of common stock) of any shares issued. The power to issue preferred stock could have the effect of delaying or preventing a change in control of the Company even if a change in control were in the shareholders' interest.

Certain provisions of Maryland law could inhibit changes in control, which may discourage third parties from conducting a tender offer or seeking other change of control transactions that could involve a premium price for our common stock or that our shareholders otherwise believe to be in their best interest.

Certain provisions of the Maryland General Corporation Law ("MGCL") may have the effect of inhibiting a third-party from making a proposal to acquire us or of impeding a change of control under circumstances that otherwise could provide the holders of shares of our capital stock with the opportunity to realize a premium over the then-prevailing market price of such shares, including:

•"Business combination" provisions that, subject to limitations, prohibit certain business combinations between us and an "interested shareholder" (defined generally as any person who beneficially owns 10% or more of the voting power of our shares or an affiliate thereof or an affiliate or associate of ours who was the beneficial owner, directly or indirectly, of 10% or more of the voting power of our then outstanding voting stock at any time within the two-year period immediately prior to the date in question) for five years after the most recent date on which the shareholder becomes an interested shareholder, and thereafter impose fair price and / or supermajority and shareholder voting requirements on these combinations; and
•"Control share" provisions that provide that "control shares" of our company (defined as shares that, when aggregated with other shares controlled by the shareholder, entitle the shareholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a "control share acquisition" (defined as the direct or indirect acquisition of ownership or control of issued and outstanding "control shares") have no voting rights except to the extent approved by our shareholder by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

The provisions of the MGCL relating to business combinations do not apply, however, to business combinations that are approved or exempted by our Board of Directors prior to the time that the interested shareholder becomes an interested shareholder. As permitted by the statute, our Board of Directors has by resolution exempted Milton M. Shiffman, Robert B. Bayer and Gary A. Shiffman, their affiliates and all persons acting in concert or as a group with the foregoing, from the business combination provisions of the MGCL and, consequently, the five-year prohibition and the supermajority vote requirements will not apply to business combinations between us and these persons. As a result, these persons may be able to enter into business combinations with us that may not be in the best interests of our shareholder without compliance by our company with the supermajority vote requirements and the other provisions of the statute.

Also, pursuant to a provision in our bylaws, we have exempted any acquisition of our stock from the control share provisions of the MGCL. However, our Board of Directors may, by amendment to our bylaws, opt into the control share provisions of the MGCL at any time in the future.

Additionally, Subtitle 8 of Title 3 of the MGCL permits our Board of Directors, without shareholder approval and regardless of what is currently provided in our charter or bylaws, to elect to be subject to certain provisions relating to corporate governance that may have the effect of delaying, deferring or preventing a transaction or a change of control of our company that might involve a premium to the market price of our common stock or otherwise be in our shareholders' best interests. These provisions include a classified board; two-thirds vote to remove a director; that the number of directors may only be fixed by the Board of Directors; that vacancies on the board as a result of an increase in the size of the board or due to death, resignation or removal can only be filled by the board, and the director appointed to fill the vacancy serves for the remainder of the full term of the class of director in which the vacancy occurred; and a majority requirement for the calling by shareholders of special meetings. Other than a classified board, the filling of vacancies as a result of the removal of a director and a majority requirement for the calling by shareholders of special meetings, we are already subject to these provisions, either by provisions of our charter and bylaws unrelated to Subtitle 8 or by reason of an election to be subject to certain provisions of Subtitle 8. In the future, our Board of Directors may elect, without shareholder approval, to make us subject to the provisions of Subtitle 8, to which we are not currently subject.

Our Board of Directors has power to adopt, alter or repeal any provision of our bylaws or make new bylaws, provided, however, that our shareholders may alter or repeal any provision of our bylaws and adopt new bylaws if any such alteration, repeal or adoption is approved by the affirmative vote of a majority of all votes entitled to be cast on the matter.

GENERAL RISK FACTORS

Ineffective succession planning for our CEO may impact the execution of our strategic plan.

On November 5, 2024, Gary A. Shiffman, our Chairman and CEO, informed the Board of Directors of his intent to retire as CEO following the expected appointment of his successor by the end of the year ending December 31, 2025. We may not effectively or appropriately identify suitable succession candidates for Gary A. Shiffman, which could have a material adverse effect on our business, financial condition and results of operations. Management continues to strengthen our team and the Board of Directors has established a CEO Succession Planning Committee to conduct a comprehensive search process to identify a new CEO, but there can be no assurance that such planning will be capable of implementation or that our efforts will be successful.

We have identified a material weakness in our internal controls over financial reporting 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. As described in Part II, Item 9A, "Controls and Procedures," management identified a material weakness as of December 31, 2024 relating to the lack of an effective risk assessment process that defined clear financial reporting objectives, that identified and evaluated risks of misstatement due to errors over certain financial reporting processes, or that developed internal controls to mitigate those risks. As part of management's evaluation of this material weakness, it has been identified that certain other deficiencies in control activities have materialized as a result of the deficiency in the Company's risk assessment.

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 updated controls have operated for a sufficient period of time and management has concluded, through testing, that such controls are 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 weaknesses in our internal control over financial reporting that management has concluded exist or existed in connection with preparing our financial statements for the years ended December 31, 2024 and 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.


23
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 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," and Note 6, "Goodwill and Other Intangible Assets," 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 UK reporting segment that we recognized during the years ended December 31, 2024 and 2023.

Our share price could be volatile and could decline, resulting in a substantial or complete loss on our shareholders' investment.
Our common stock has experienced significant price and volume fluctuations. In the future, the market price of our common stock and preferred stock could be similarly volatile, and investors in our common stock and preferred stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. The price of our common stock and preferred stock could be subject to wide fluctuations in response to a number of factors, including:

•issuances of other equity securities in the future, including new series or classes of preferred stock;
•our operating performance and the performance of other similar companies;
•our ability to maintain compliance with covenants contained in our debt facilities and our unsecured notes;
•actual or anticipated variations in our operating results, funds from operations, cash flows or liquidity;
•changes in expectations of future financial performance or changes in our earnings estimates or those of analysts;
•changes in our distribution policy;
•publication of research reports about us or the real estate industry generally;
•increases in market interest rates that lead purchasers of our common stock and preferred stock to demand a higher dividend yield;
•changes in foreign currency exchange rates, including between the U.S. dollar and each of the Canadian dollar, Australian dollar and pound sterling;
•changes in market valuations of similar companies;
•outbreaks of disease, and related restrictions on business operations;
•adverse market reaction to the amount of our debt outstanding at any time, the amount of our debt maturing in the near-term and medium-term and our ability to refinance our debt, or our plans to incur additional debt in the future;
•additions or departures of key management personnel;
•speculation in the press or investment community;
•equity issuances by us, or share resales by our shareholders or the perception that such issuances or resales may occur;
•actions by institutional shareholders;
•litigation or threatened litigation, which may divert our management's time and attention, require us to pay damages and expenses or restrict the operation of our business;
•failure to qualify and maintain our qualification as a REIT; and
•general market and economic conditions.

24
SUN COMMUNITIES, INC.
Many of the factors listed above are beyond our control. Those factors may cause the market price of our common stock or preferred stock to decline significantly, regardless of our financial condition, results of operations and prospects. It is impossible to provide any assurance that the market price of our common stock or preferred stock will not fall in the future, and it may be difficult for holders to resell shares of our common stock or preferred stock at prices they find attractive, or at all. In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management's attention and resources.

Substantial sales or issuances of our common or preferred stock could cause our stock price to fall.

The sale or issuance of substantial amounts of our common stock or preferred stock, whether directly by us or in the secondary market, the perception that such sales could occur or the availability of future issuances of shares of our common stock, preferred stock, OP units or other securities convertible into or exchangeable or exercisable for our common stock or preferred stock, could materially and adversely affect the market price of our common stock or preferred stock and our ability to raise capital through future offerings of equity or equity-related securities. In addition, we may issue capital stock that is senior to our common stock in the future for a number of reasons, including to finance our operations and business strategy, to adjust our ratio of debt to equity or for other reasons.

Based on the applicable conversion ratios then in effect, as of February 21, 2025, in the future we may issue to the limited partners of the Operating Partnership, up to approximately 5.3 million shares of our common stock in exchange for their OP units. The limited partners may sell such shares pursuant to registration rights, if available, or an available exemption from registration. As of February 21, 2025, there were no outstanding options to purchase shares of our common stock under our equity incentive plans, and we had the authority to issue restricted stock awards or options to purchase up to an additional 2.8 million shares of our common stock pursuant to our equity incentive plans. In addition, we have entered into an At the Market Offering Sales Agreement to sell shares of common stock. As of December 31, 2024, we have remaining capacity to sell up to an additional $725.2 million of common stock under this agreement. No prediction can be made regarding the effect that future sales of shares of our common stock or our other securities will have on the market price of shares.

Our business operations may not generate the cash needed to make distributions on our capital stock or to service our debt, and we may adjust our common stock distribution policy.

Our ability to make distributions on our common stock and preferred stock, and payments on our debt and to fund planned capital expenditures will depend on our ability to generate cash in the future. We cannot assure you that our business will generate sufficient cash flows from operations or that future borrowings will be available to us in an amount sufficient to enable us to make distributions on our common stock or preferred stock, to pay our debt or to fund our other liquidity needs.

The decision to declare and pay distributions on shares of our common stock in the future, as well as the timing, amount and composition of any such future distributions, will be at the sole discretion of our Board of Directors in light of conditions then existing, including our earnings, financial condition, capital requirements, debt maturities, the availability of debt and equity capital, applicable REIT and legal restrictions, general overall economic conditions and other factors. Any change in our distribution policy could have a material adverse effect on the market price of our common stock.

We rely on key management.

We depend on the efforts of our executive officers, including Gary A. Shiffman, John B. McLaren, Bruce D. Thelen, Fernando Castro-Caratini, Marc Farrugia, Aaron Weiss and Baxter R. Underwood. The loss of services of one or more of these executive officers could have a temporary adverse effect on our operations. We do not currently maintain or contemplate obtaining any "key-man" life insurance on our executive officers.

Cybersecurity breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

We rely intensively on information technology to account for tenant transactions, manage the privacy of tenant data, communicate internally and externally, and analyze our financial and operating results. In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and that of our tenants, clients, vendors and employees in our facilities and on our network. In addition, we engage third party service providers that may have access to such information in connection with providing necessary information technology and security and other business services to us. This information may include personally identifiable information such as social security numbers, banking information and credit card information.


25
SUN COMMUNITIES, INC.
We address potential breaches or disclosure of this 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.

Despite our security measures, our information technology and infrastructure, as well as that of our third-party vendors, may be vulnerable to attacks by hackers (including through malware, ransomware, computer viruses and email phishing schemes) or breached due to employee error, malfeasance, fire, flood or other physical event, or other disruptions. Any such breach or disruption could compromise our or a third-party vendor's network and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could:

•result in legal claims or proceedings,
•disrupt our operations, including our ability to service our tenants and our ability to analyze and report our financial and operating results,
•decrease our revenues,
•damage our reputation,
•cause a loss of confidence,
•increase our insurance premiums, or
•have other material adverse effects on our business.

We depend on continuous access to the internet to use our cloud-based applications. Damage to, or failure of our information technology systems, including as a result of any of the reasons described above, could adversely affect our results of operations as we may incur significant costs or data loss. We continually assess new and enhanced information technology solutions to manage the risk of system failure or interruption.

Losses in excess of our insurance coverage or uninsured losses could adversely affect our operating results and cash flows and upon renewal of our insurance policies, our coverage may change and our costs may increase, including our assumption of a greater proportion of risk through self-insurance.

We have a significant concentration of MH and RV properties and marinas on coastlines and in other areas where natural disasters or other catastrophic events such as hurricanes, flash floods, sea-level rise, droughts, tornadoes, wildfires or earthquakes could negatively impact our operating results and cash flows. We maintain comprehensive liability, fire, property, business interruption, general liability, and (where appropriate) flood and earthquake insurance, and other lines of insurance we have determined to be appropriate for our business through a combination of self-insurance partially covering the risk and insurance provided by reputable companies with commercially reasonable deductibles and limits. We believe the policy specifications and insured limits are appropriate and adequate given the relative risk of loss, the cost of the coverage and industry practice. However, certain types of losses including, but not limited to, riots or acts of war, may be either uninsurable or not economically insurable. In the event an uninsured loss occurs, we could lose both our investment in and anticipated profits and cash flows from the affected property. We would also continue to be obligated to repay any mortgage debt or other obligations related to the community. If an uninsured liability to a third party were to occur, we would incur the cost of defense and settlement with, or court ordered damages to, that third party. A significant uninsured property or liability loss could have a material adverse effect on our business and our financial condition and results of operations.

We renew our insurance policies annually. As a result of increased insurance claims across the industry and other market conditions, it has been more difficult to obtain insurance, but in particular property insurance covering named windstorms, business interruption, flood and earthquake insurance. There are fewer insurers willing to provide policies, and policies increasingly include lower coverage limits, higher deductibles and higher premiums. These conditions may cause us to change the types and amounts of insurance we carry and may provide us with reduced coverage and / or higher costs. This has resulted in a change in our insurance purchasing philosophy and strategy which has resulted in the assumption of greater risks to offset insurance market fluctuations.

Expanding social media platforms present new challenges.

Social media outlets continue to grow and expand, which presents us with new risks. Adverse content about us and our properties on social media platforms could result in damage to our reputation or brand. Improper posts by employees or others could result in disclosure of confidential or proprietary information regarding our operations.

26
SUN COMMUNITIES, INC.
Our operations are subject to regulation under various federal, state, local and foreign laws and regulations that may expose us to significant costs and liabilities.

Our properties and the operations at them are subject to regulation under various federal, state, local and foreign laws and regulations. Compliance with laws and regulations that govern our operations may require expenditures and modifications of development plans and operations that could have a detrimental effect on the operations of our properties and our financial condition, results of operations and cash flows. There can be no assurance that the application of laws, regulations or policies, or changes in such laws, regulations and policies, will not occur in a manner that could have a detrimental effect on any property.

We may be adversely impacted by fluctuations in foreign currency exchange rates.

Our current and future investments in and operations of Canadian, Australian, and UK properties are or will be exposed to the effects of changes in the Canadian dollar, Australian dollar and pound sterling, respectively, against the U.S. dollar. Changes in foreign currency exchange rates cannot always be predicted; as a result, substantial unfavorable changes in exchange rates could have a material adverse effect on our financial condition and results of operations.

Deterioration in general economic conditions in the United States, and globally, including the effect of prolonged periods of inflation, could harm our business and results of operations.

Our business and results of operations could be adversely affected by changes in national or global economic conditions. These conditions include but are not limited to inflation, deflation, rising interest rates, availability of capital markets, energy availability and costs, the negative impacts caused by outbreaks of disease and public health crises, negative impacts resulting from military conflicts and the effects of governmental initiatives to manage economic conditions.

Risk Management

Our business operations rely on the consistent availability of our communication platforms, enterprise applications, and related systems. We have implemented protocols to ensure the secure collection, storage, and transmission of data and have invested in the development and enhancement of controls designed to prevent, detect, and respond to unauthorized access, computer viruses, malware, data exfiltration, and other threats.

We have established an Information Security Management Committee to manage information security in accordance with the ISO 27001 standard to ensure the consistent application of security principles, policy statements and controls. By adhering to this industry standard, we manage and mitigate material risks from threats to our systems and data through the following actions:

•Partnering with reputable, recognized security firms
•Conducting regular internal and external audits and risk assessments
•Providing ongoing employee security awareness training
•Conducting tabletop exercises
•Running anti-phishing campaigns and simulated phishing exercise
•Deploying tools for continuous vulnerability monitoring
•Performing penetration testing and continuous system monitoring activities
•Conducting recovery simulations for core systems and data centers

Our comprehensive policies and procedures address critical areas including:

•Vulnerability management
•Business continuity planning
•Encryption of sensitive data
•Backup and recovery

SUN COMMUNITIES, INC.
•Physical security
•User access controls
•Vendor risk management
•Teleworking protocols
•Mobile device management
•Comprehensive system monitoring

These initiatives collectively reinforce our commitment to safeguarding information and ensuring the resilience of our security infrastructure. Comprehensive contingency and recovery plans are in place to ensure the ongoing provision of services to customers in the event of a cybersecurity incident. These are tested on a regular basis against scenarios of varying degrees by both internal and external resources.

To manage vendor risk, we conduct ongoing risk assessments based on the vendor's published Systems and Operational Controls ("SOC") reports, information provided in vendor security questionnaires, and any publicly available information including ongoing litigation or external disclosures.

As of the time of this filing, we are not aware of any cybersecurity incidents that have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial conditions. Refer to "Risk Factors" in Part I, Item 1A in this Annual Report on Form 10-K under the heading "Cybersecurity breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer," for additional discussion about cybersecurity related risks.

Governance

Senior leadership provides the Board of Directors with ongoing security updates, which include notable changes to program plans, changes to the risk environment, information regarding material incidents that may have occurred, third-party audit reports on recent assessments of our security controls, and details regarding forward-looking plans and strategies to mitigate cyber risk. The Audit Committee of the Board of Directors provides oversight and is responsible for assessing risks to our business, in accordance with its charter. The Audit Committee engages in regular conversations with senior leadership about our security systems in order to monitor and mitigate risks from cybersecurity incidents, in accordance with our security principles and protocols.

The Chief Information Officer (CIO) and the Director of Information Security are directly responsible for managing cyber risk on a daily basis. The CIO reports to the Chief Administrative Officer (CAO), who oversees the Company's overall information technology strategy and governance. Executive oversight, spearheaded by the CAO, ensures strategic alignment across the organization. With a wealth of leadership in both public and private sectors, these individuals collectively possess years of invaluable experience in information technology and security.

The Information Security Management Committee (ISMC) and Enterprise Risk Management Committees (ERM) meet regularly to provide oversight of cyber risk management functions. Committee composition includes members from cross-functional departments, including technology, innovation, human resources, accounting and finance, internal audit, operations and executive management. Various members of these committees hold industry certifications representing expertise in information security risk and compliance management, including the Certified Information Technology Professional (CITP), Certified Information Systems Security Professional (CISSP), Certified Information Security Auditor (CISA), and Certified in Risk and Information Systems Control (CRISC) designations.

ITEM 2. PROPERTIES

As of December 31, 2024, our properties were located in the U.S., the UK and Canada, and consisted of 288 MH communities, 166 RV communities, 138 marinas, and 53 UK communities.

As of December 31, 2024, our properties contained an aggregate of 225,150 developed sites comprised of 97,430 developed MH sites, 32,100 annual RV sites (inclusive of both annual and seasonal usage rights), 24,830 transient RV sites, 17,690 UK annual sites, 4,340 UK transient RV sites, and 48,760 wet slips and dry storage spaces. There are 16,570 additional MH, RV, and UK sites suitable for development. Most of our properties include amenities oriented toward family and retirement living. Of our 645 properties, 316 properties have 300 or more developed sites, with the largest having 2,340 developed MH and RV sites. See "Real Estate and Accumulated Depreciation, Schedule III," included in our Consolidated Financial Statements, for detail on properties that are encumbered.

As of December 31, 2024, our MH and RV properties had an occupancy rate of 97.0% excluding transient RV sites. Since January 1, 2020, our MH and RV properties have a five-year average annual turnover of homes (where the home is moved out of the community) of approximately 3.4% and a five-year average annual turnover of residents (where the resident-owned home is sold and remains within the community, typically without interruption of rental income) of approximately 6.3%. The average renewal rate for residents in our Rental Program was 68.1% for the year ended December 31, 2024.

We believe that our properties' high amenity levels, customer service loyalty, and customer retention program contribute to low turnover and generally high occupancy rates. All of the properties provide residents with attractive amenities with most offering a clubhouse, a swimming pool and laundry facilities. Many of the properties offer additional amenities such as sauna / whirlpool spas, tennis courts, shuffleboard, basketball courts and / or exercise rooms. Many RV communities offer incremental amenities including golf, pro shops, restaurants, zip lines, waterparks, watersports, and thematic experiences.

Our MH and RV communities are principally located in the midwestern, southern and southeastern regions of the U.S., in the south of England in the UK and in Canada. Our marinas are principally located in the northeastern, southern, mid-Atlantic, western and midwestern regions of the U.S., with the majority of such marinas concentrated in coastal regions, and others located in various inland regions. We believe that geographic diversification helps to insulate the portfolio from regional economic influences. We have concentrated our properties within certain areas of the regions in order to achieve economies of scale in management and operations.

The following tables set forth certain information relating to our MH, RV, and UK properties as of December 31, 2024. The occupancy percentage includes MH sites and annual RV sites and excludes transient RV sites.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and accompanying footnotes thereto included in this Annual Report on Form 10-K. In addition to the results presented in accordance with GAAP below, we have provided NOI and FFO information as supplemental performance measures. Refer to Non-GAAP Financial Measures in this Item 7 for additional information.

OVERVIEW AND OUTLOOK
We are a fully integrated REIT. As of December 31, 2024, we owned and operated, directly or indirectly, or had an interest in, a portfolio of 645 developed properties located in the U.S., Canada, and the UK including 288 MH communities, 166 RV communities, 138 marinas and 53 UK communities.

We have been in the business of acquiring, operating, developing and expanding MH and RV communities since 1975, marinas since 2020, and communities in the UK since 2022. We lease individual parcels of land, or sites, with utility access for the placement of manufactured homes and RVs to our MH, RV, and UK customers. Our MH communities are designed to offer affordable housing to individuals and families, while also providing certain amenities. In the U.S., we also market, sell, and lease new and pre-owned homes to current and future residents in our MH communities. The rental program operations within our MH communities support and enhance our occupancy levels, property performance, and cash flows. 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. In the UK, our Park Holidays communities are referred to as "holiday parks" and are located predominantly at irreplaceable seaside destinations in the south of England. We provide holiday home sales and associated site license activities to holiday homeowners in our communities.

Historically, a large component of our growth was driven by acquisitions as we opportunistically purchased high-quality MH, RV, Marina, and UK properties. With the benefit of our expanded portfolio, beginning in 2023, we shifted our strategy toward optimizing the value of our existing businesses through achieving strong rental rate growth and operating efficiencies, while still pursuing select new acquisition and expansion opportunities. This strategy continued in 2024 as we determined to divest non-strategic assets and focus on simplification of our operations and capital structure. During the year ended December 31, 2024, we sold 25 properties and three development properties for a total gross sales price of $476.8 million and commenced an internal restructuring initiative. We remain focused on maximizing Real property income, Same Property NOI growth, and Core FFO per share growth, which we believe will enhance long-term shareholder value.

Leadership Change

In November 2024, Gary A. Shiffman informed the Board of his intent to retire as CEO by no later than December 31, 2025. The Board of Directors has established a CEO Succession Planning Committee to conduct a comprehensive search process to identify a new CEO.

Catastrophic Event - Hurricanes Helene and Milton

In September and October 2024, Hurricane Helene and Hurricane Milton, respectively, made landfall in Florida and subsequently impacted several of our properties in the Southeastern and Mid-Atlantic regions of the U.S. During the year ended December 31, 2024, we recognized charges of $13.9 million for debris removal and clean-up at several of our MH and RV communities, and charges of $4.4 million for impaired assets at several of our marinas, which were recorded within Catastrophic event-related charges, net on the Consolidated Statements of Operations. We maintain property, casualty, flood, and business interruption insurance for our properties, subject to customary deductibles and limits.

EXECUTIVE SUMMARY

2024 General Overview

Key operational and financial highlights included the following:

•Total revenues for 2024 were $3.2 billion, consistent with 2023 total revenues.
•Net income attributable to SUI common shareholders was $89.0 million, as compared to a net loss attributable to SUI common shareholders of $213.3 million in the prior year, driven primarily by Same Property NOI generation and gains on dispositions of assets.
•Achieved annual Core FFO of $6.81 per diluted share and OP unit.
•Achieved Real property Same Property NOI growth of 6.7% for MH, 5.4% for Marina and 9.0% for the UK over 2023. For the RV segment, we experienced a decline in Same Property NOI growth of 2.8%, driven by lower than anticipated real property - transient revenues and an increase in supplies and repair expenses and other expenses.
•Increased Same Property adjusted blended occupancy for MH and RV by 160 basis points to 99.0% as compared to 97.4% in 2023.
•Entered into and settled all outstanding forward sale agreements with respect to 2,713,571 shares of common stock under our At the Market Offering Sales Agreement. Net proceeds of $361.7 million were used to repay borrowings outstanding under our senior credit facility.
•Closed an offering of underwritten senior unsecured notes of $500.0 million for net proceeds of $495.4 million of which a majority of the net proceeds were used to reduce floating-rate debt.
•Completed the disposition of non-strategic properties valued at $476.8 million in aggregate, including an exit from two states.
•Reduced our Net debt / trailing twelve month recurring EBITDA ratio to 6.0x as of December 31, 2024 (from 6.1x in the prior year) and reduced floating rate debt exposure to 8.6% as of December 31, 2024 (from 16.4% as of December 31, 2023).

Property Operations

Occupancy in our MH and annual RV properties, as well as our ability to increase rental rates, directly affect revenues. Our revenue streams are predominantly derived from customers renting our sites on a long-term basis. Our Same Property communities continue to achieve revenue and occupancy increases which drive continued NOI growth. Our Same Property marinas and UK communities achieved revenue increases which contributed to our NOI growth.

Acquisition Activity

During the year ended December 31, 2024, we acquired three marinas and three marina expansion assets with an aggregate of 925 wet slips and dry storage spaces for an aggregate purchase price of approximately $63.8 million. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for details of our acquisition activities.

SUN COMMUNITIES, INC.
Disposition Activity

Management continually evaluates properties within the portfolio for potential disposition opportunities. When a given property no longer fits our desired growth profile, we seek to redeploy capital to properties and geographies fit to provide greater future returns. From time to time, strategic reductions to the portfolio are necessary to reduce exposure to less desirable locations and support our long-term positioning. In 2024, we expanded our disposition program as part of our strategy to focus on simplification of our operations and capital structure.

During the year ended December 31, 2024, we sold 25 communities located in the U.S, Canada, and the U.K., with 6,526 sites for $426.6 million. In addition, we sold three development properties in the U.S. for total consideration of $50.2 million. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for details on the disposition activities.

Markets

Our MH and RV properties are largely concentrated in the U.S. in Florida, Michigan, Texas, and California, which collectively contain 63.9% of our total MH and RV sites. We have expanded our market share in multiple states through acquisitions and increased our property holdings in high-growth areas of the U.S. including retirement and vacation destinations. The age demographic of RV communities is attractive, as the population of retirement age adults in the U.S. is growing. RV communities have become a trending vacation opportunity not only for the retiree population, but as an affordable vacation alternative for families and millennials.

The majority of our marinas are concentrated in coastal regions, and other marinas are located in various inland regions. Our Marina properties are largely concentrated in the U.S. in Florida and California, which collectively contain 23.6% of our total wet slips and dry storage spaces.

Our UK properties are located in irreplaceable coastal destination locations that are a short drive from London and other urban locations. Our UK properties are largely concentrated in England, which contain 93.3% of our total holiday parks.

NON-GAAP FINANCIAL MEASURES
In addition to the results reported in accordance with GAAP in our "Results of Operations" below, we have provided information regarding net operating income ("NOI") and funds from operations ("FFO") as supplemental performance measures. We believe NOI and FFO are appropriate measures given their wide use by and relevance to investors and analysts following the real estate industry. 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 GAAP depreciation / amortization of real estate assets. In addition, NOI and FFO are commonly used in various ratios, pricing multiples / yields and returns and valuation calculations used to measure financial position, performance and value.

NOI

Total Portfolio NOI - NOI is derived from property operating revenues minus property operating expenses and real estate taxes. NOI is a non-GAAP financial measure that we believe 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. We use 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 our properties rather than of the Company overall. We believe that NOI provides enhanced comparability for investor evaluation of properties' performance and growth over time.

We believe 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 our financial performance or GAAP cash flow from operating activities as a measure of our liquidity; nor is it indicative of funds available for our cash needs, including our 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.


51
SUN COMMUNITIES, INC.
Same Property NOI - This is a management tool used when evaluating the performance and growth of our Same Property portfolio. We define same properties as those we have owned and operated continuously since January 1, 2023. Same properties exclude ground-up development properties, acquired properties and properties sold after December 31, 2022. The Same Property data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions or unique situations. Same Property NOI does not include the revenues and expenses related to home sales, and service, retail, dining and entertainment activities at the properties. We believe that Same Property NOI is helpful to investors as a supplemental comparative performance measure of the income generated from the Same Property portfolio from one period to the next.

FFO

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 certain real estate assets, plus real estate related depreciation and amortization, impairments of certain real estate assets and investments, and after adjustments for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of our operating performance. By excluding gains and losses related to sales of previously depreciated operating real estate assets, real estate related to impairment, and real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period-over-period, reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from GAAP net income (loss). Management believes the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful.

Core FFO - In addition, we use FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business ("Core FFO").

We believe that FFO and Core FFO provide enhanced comparability for investor evaluations of period-over-period results. We believe that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a financial performance measure or GAAP cash flow from operating activities as a measure of our liquidity. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Furthermore, FFO is not intended as a measure of a REIT's ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO is calculated in accordance with our interpretation of standards established by Nareit, which may not be comparable to FFO reported by other REITs that interpret the Nareit definition differently.

Seasonality of Revenue

The RV, Marina, and UK segments are seasonal and the results of operations in any one period may not be indicative of results in future periods.

In the RV segment, certain properties maintain higher occupancy during the summer months, while other properties maintain higher occupancy during the winter months. Based on the location of our properties with transient RV sites, our portfolio generally produces higher revenues between April and September than between October and March. In the UK segment, vacation rental sites generally produce higher revenues between March and October. The following table presents the seasonality of real property-transient revenue for the years ended December 31, 2024, 2023, and 2022:

In the Marina segment, the majority of our wet slip and dry storage space leases have annual terms that are billed seasonally. Wet slip storage increases during the summer months for the boating season, whereas dry storage increases during the winter season as weather patterns require boat owners to store their vessels on dry docks or within covered racks.

Real Property Operations - Same Property Portfolio

Same Property refers to properties that we have owned for at least the preceding year, exclusive of properties recently completed or under construction, and other properties as determined by management. The Same Property data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions or unique situations.

In order to evaluate the growth of the Same Property portfolio, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Property portfolio is the reclassification of utility revenues from real property revenue to operating expenses. A significant portion of our utility charges are re-billed to our residents. Additionally, for the MH, RV, and UK segments, the amounts in the tables below reflect constant currency for comparative purposes. Additionally, prior period Canadian dollar and pound sterling currency figures have been translated at 2024 average exchange rates for constant currency comparability.

NOI - North America
For the year ended December 31, 2024, the 34.4% decrease in NOI is primarily driven by a 22.0% decrease in total home sales volume as compared to the same period in 2023, primarily driven by the impact of Hurricanes Helene and Milton on volumes in the southeast region of the U.S., and fewer available sites to sell homes on in conjunction with reduced expansion and development activity, as well as a 360 basis point decrease in margins, driven by the decrease in home sales volumes causing home sales revenue to decline at a faster rate than home cost and selling expenses.

NOI - UK
For the year ended December 31, 2024, the 1.8% increase in NOI is primarily driven by a 3.2% increase in total home sales volume, partially offset by a 1.7% reduction in average selling price, as compared to the same period in 2023.

N/M = Percentage change is not meaningful. N/A = Not applicable.

Service, retail, dining and entertainment, net - for the year ended December 31, 2024, decreased primarily due to lower transient demand in the RV and Marina segments leading to a reduction in revenue generation from service, retail, dining and entertainment activities, as well as increased costs related to service and retail activities in our Marina segment.

Interest income - for the year ended December 31, 2024, decreased primarily due to having a lower receivable balance outstanding with real estate operators than during the same period in 2023. Refer to Note 4, "Notes and Other Receivables," in our accompanying Consolidated Financial Statements for additional information.

Brokerage commissions and other, net - for the year ended December 31, 2024, decreased primarily due to a decrease in business interruption recoveries recognized in 2024 as compared to the same period in 2023, a decrease in the number of brokered home sales reducing total brokerage commissions as compared to the same period in 2023, and a decrease in dividend income as a result of the sale of our publicly traded marketable securities in Ingenia Communities Group ("Ingenia") in 2023. Refer to Note 16, "Commitments and Contingencies," in our accompanying Consolidated Financial Statements for additional information.

Catastrophic event-related charges, net - for the year ended December 31, 2024, increased, primarily due to charges of $18.3 million for debris removal and clean-up and impaired assets at several of our MH, RV, and marina properties due to Hurricanes Helene and Milton, and incremental asset impairment and debris removal charges, net of insurance recoveries, of $5.6 million driven by flooding at an RV community in New Hampshire.


63
SUN COMMUNITIES, INC.
Asset impairments - for the year ended December 31, 2024, increased due to impairment charges of $24.1 million related to non-continuing expansion and development properties within our MH and RV segments, and impairment charges of $21.1 million related to a portfolio of four RV communities and two development properties that were classified as held for sale and subsequently sold.

LIQUIDITY AND CAPITAL RESOURCES

Short-term Liquidity

Our principal short-term liquidity demands historically have been, and are expected to continue to be, distributions to our shareholders and the unit holders of the Operating Partnership, property acquisitions, development and expansion of our properties, capital improvement of our properties, the purchase of new and pre-owned homes, and debt repayment. We intend to meet our short-term liquidity requirements through available cash balances, cash flow generated from operations, draws on our senior credit facility, and the use of debt and equity offerings under our shelf registration statement. Refer to Note 8, "Debt and Line of Credit," Note 9, "Equity and Temporary Equity" and Note 20, "Subsequent Events," in our accompanying Consolidated Financial Statements for additional information and related activity subsequent to December 31, 2024.

We intend to continue to strengthen our capital and liquidity positions by focusing on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We take a disciplined approach to selecting the optimal mix of financing sources to meet our liquidity demands and minimize our overall cost of capital. Our investment grade credit ratings remain unchanged from the initial rating. We plan to continue to capitalize on our unsecured bond market access to optimize our cost of capital and increase our financial flexibility.

Current market and economic conditions, including relating to, among other things, interest rates, currency fluctuations, equity valuations and inflation, may adversely affect our ability to obtain debt and equity capital in the short term on attractive terms.

Since our initial public offering in 1993, we have demonstrated operational reliability and cash flow strength throughout economic cycles. Our current objectives include streamlining our operations with an emphasis on our reliable real property income. We recognize the headwinds we are facing from a challenging macroeconomic environment and are re-aligning our strategy to focus on our proven, durable income streams. We are positioned for ongoing organic growth with expected rental rate increases, occupancy gains and expense management. In 2025, we expect rental rate growth that exceeds headline inflation with ongoing focus on expense management to continue generating strong organic cash flow growth.

Given a macroeconomic backdrop of sustained higher interest rates, we intend to prioritize debt reduction as our primary use of free cash flow from our operations and of proceeds from equity issuances and selective capital recycling. In addition, we are reducing our development activity considering the more challenging macroeconomic and capital market environment. Capital spending besides projects that are underway will be solely focused on the most strategic opportunities. We also attempt to manage interest rate risks by using interest rate hedging instruments and by monitoring our overall leverage levels. We engage in certain hedging transactions to limit our exposure from the adverse effects of changes in interest rates on borrowing costs of our loans.

Acquisitions, Dispositions, Development and Expansion Activities

Subject to market conditions, we intend to selectively identify opportunities to expand our development pipeline and acquire existing properties. We finance acquisitions through available cash, secured financing, draws on our senior credit facility, the assumption of existing debt on properties and the issuance of debt and equity securities. Given the higher interest rate environment, we continue to selectively pursue acquisition and development opportunities that meet our underwriting criteria.

During the year ended December 31, 2024, we acquired three marinas and three marina expansion assets with an aggregate of 925 wet slips and dry storage spaces for an aggregate purchase price of approximately $63.8 million. In conjunction with two of the marina acquisitions, we issued an aggregate of 262,599 common OP units as part of the consideration transferred. During the same period, we entered into a ground lease that can support one marina with eight wet slips and dry storage spaces.

We have commenced a targeted disposition program to divest non-strategic assets in an effort to simplify management and reduce total debt. During and subsequent to the year ended December 31, 2024, we sold 10 MH properties, 17 RV properties, two UK properties, and three MH development properties with an aggregate of 7,341 sites for a gross sale price of approximately $569.7 million, and received total cash consideration of approximately $419.3 million, net of settlement of the associated mortgage debt of $93.5 million. The net proceeds were used to repay borrowings outstanding under the senior credit facility.

During the year ended December 31, 2024, we acquired two land parcels located in the U.S. for an aggregate purchase price of $12.9 million. The parcels can accommodate the potential development of over 1,100 sites. We also acquired two land parcels located in the U.K. for an aggregate purchase price of $11.6 million. We also expanded two of our existing communities by over 70 sites and delivered nearly 100 sites at two ground-up development properties.


66
SUN COMMUNITIES, INC.
We plan to selectively expand our properties utilizing our inventory of owned and entitled land. We have 16,570 MH and RV sites suitable for future development.

Refer to Note 3, "Real Estate Acquisitions and Dispositions," in our accompanying Consolidated Financial Statements for additional details on acquisitions and dispositions completed to date.

Total Non-Recurring Capital Expenditure and Related Activities537.2 915.7 
Total Capital Expenditure and Related Activities$652.9 $1,003.0 

Recurring Capital Expenditures

Property recurring capital expenditures are necessary to maintain asset quality, including purchasing and replacing items used to operate the communities and marinas. Recurring capital expenditures at our MH, RV, and UK properties include major road, driveway and pool improvements; clubhouse renovations; adding or replacing streetlights; playground equipment; signage; maintenance facilities; manager housing; and property vehicles. Recurring capital expenditures at our marinas include dredging, dock repairs and improvements, and equipment maintenance and upgrades. The minimum capitalized amount is five hundred dollars.

Non-Recurring Capital Expenditures and Related Activities

Lot modifications - consist of expenditures incurred to modify the foundational structures required to set a new home after a previous home has been removed. These expenditures are necessary to create a revenue stream from a new site renter and often improve the quality of the community. Other lot modification expenditures include land improvements added to annual RV sites to aid in the conversion of transient RV guests to annual contracts.

Growth projects - consist of revenue generating or expense reducing activities at the properties. These include, but are not limited to, utility efficiency and renewable energy projects, site, slip or amenity upgrades such as the addition of a garage, shed or boat lift, and other special capital projects that substantiate an incremental rental increase.

Rebranding - includes new signage at our RV communities and the costs of building an RV mobile application and updated website.

Capital improvements to recent acquisitions - often require 24 to 36 months to complete after closing and include upgrading clubhouses; landscaping; new street light systems; new mail delivery systems; pool renovations including larger decks, heaters and furniture; new maintenance facilities; lot modifications; and new signage including main signs and internal road signs.

Expansion and development expenditures - consist primarily of construction costs such as roads, activities, and amenities, and costs necessary to complete site improvements, such as driveways, sidewalks, and landscaping at our MH, RV, and UK communities. Expenditures also include costs to rebuild after damage has been incurred at our properties, and research and development.


67
SUN COMMUNITIES, INC.
Rental program - consists of investment in the acquisition of homes intended for the rental program and the purchase of vacation rental homes at our RV communities. Expenditures for these investments depend upon the condition of the markets for repossessions and new home sales, rental homes, and vacation rental homes.

Cash Flow Activities

Our cash flow activities are summarized as follows (in millions):

Year Ended
December 31, 2024December 31, 2023December 31, 2022
Net Cash Provided By Operating Activities$861.0 $790.5 $734.9 
Net Cash Used For Investing Activities$(267.4)$(919.5)$(3,062.6)
Net Cash Provided By / (Used For) Financing Activities$(571.6)$80.3 $2,348.6 
Effect of Exchange Rate Changes on Cash, Cash Equivalents and Restricted Cash$(0.8)$1.0 $(8.7)

Cash, cash equivalents and restricted cash increased by $21.2 million from $42.7 million as of December 31, 2023, to $63.9 million as of December 31, 2024.

Operating activities - Net cash provided by operating activities increased by $70.5 million to $861.0 million for the year ended December 31, 2024, compared to $790.5 million for the year ended December 31, 2023. The increase in operating cash flow was primarily due to beneficial changes in inventory, other assets, and other liabilities, and improved Same Property operating performance at our MH properties, marinas, and UK properties, partially offset by reduced operating performance at our RV properties during the year ended December 31, 2024 as compared to the corresponding period in 2023.

Our net cash flows provided by operating activities from continuing operations may be adversely impacted by, among other things:

•the market and economic conditions in our current markets generally, and specifically in the metropolitan areas of our current markets;
•lower occupancy and rental rates of our properties;
•increases in other operating costs, such as wage and benefit costs, supplies and repairs, real estate taxes and utilities;
•substantial increases in insurance premiums;
•decreased sales of manufactured homes;
•current volatility in economic conditions and the financial markets; and
•the effects of outbreaks of disease and related restrictions on business operations.

See "Risk Factors" in Part I, Item 1A in this Annual Report on Form 10-K.

Investing activities - Net cash used for investing activities decreased by $652.1 million to $267.4 million for the year ended December 31, 2024, compared to $919.5 million for the year ended December 31, 2023. The decrease in Net cash used for investing activities was primarily driven by a decrease in cash deployed to invest in existing properties and proceeds received from the disposition of 10 MH properties, 13 RV properties, two UK properties, and three MH development properties during the year ended December 31, 2024 as compared to the corresponding period in 2023. Refer to the Consolidated Statements of Cash Flows for detail on the net cash used for investing activities during the years ended December 31, 2024 and 2023. Refer to Note 3, "Real Estate Acquisitions and Dispositions" and Note 20, "Subsequent Events," in our accompanying Consolidated Financial Statements for additional information on acquisitions and investment activity subsequent to December 31, 2024.

Financing activities - Net cash used for financing activities was $571.6 million for the year ended December 31, 2024, compared to net cash provided by financing activities of $80.3 million for the year ended December 31, 2023. The change in Net cash provided by / (used for) financing activities was primarily driven by cash disbursed to settle mortgage debt and repay borrowings outstanding under the senior credit facility, partially offset by proceeds from the issuance of equity during the year ended December 31, 2024, as compared to the net issuance of debt during the corresponding period in 2023, as part of our strategy to optimize the strength of our balance sheet. Refer to the Consolidated Statements of Cash Flows for detail on the net cash provided by / (used for) financing activities during the years ended December 31, 2024 and 2023. Refer to Note 8, "Debt and Line of Credit" in our accompanying Consolidated Financial Statements for additional information.


68
SUN COMMUNITIES, INC.
We are exposed to interest rate variability associated with our outstanding floating rate debt and any maturing debt that has to be refinanced. Interest rate movements impact our borrowing costs and, while as of December 31, 2024, approximately 91% of our total debt was fixed rate financing, including the impact of hedge activity, increases in interest costs are likely to adversely affect our financial results.

Equity and Debt Activity

At the Market Offering Sales Agreement

During May 2024, we renewed our 2021 At the Market Offering Sales Agreement ("ATM") with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock. During the three months ended September 30, 2024, we entered into forward sale agreements with respect to 2,713,571 shares of common stock under the ATM. We completed the physical settlement of these shares for an aggregate gross sales price of $364.3 million and received net proceeds of $361.7 million, or $133.31 per share. The net proceeds were used to repay borrowings outstanding under the senior credit facility. Through December 31, 2024, we had entered into and settled forward sales agreements under the ATM for an aggregate gross sales price of $524.8 million, leaving $725.2 million available for sale under the ATM.

Senior Unsecured Notes

The following table sets forth certain information regarding our outstanding senior unsecured notes (in millions, except for statistical information). All senior unsecured notes include interest payments on a semi-annual basis in arrears.

(1) In January 2024, the Operating Partnership issued $500.0 million of senior unsecured notes with an interest rate of 5.5% and a five-year term, due January 15, 2029 (the "2029 Notes"). Interest on the 2029 Notes is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on July 15, 2024. The net proceeds from the offering were $495.4 million, after deducting underwriters' discounts and offering expenses. We used the majority of the net proceeds to repay borrowings outstanding under our senior credit facility.

The obligations of the Operating Partnership to pay principal, premiums, if any, and interest on our senior unsecured notes are guaranteed on a senior basis by Sun Communities, Inc. The guarantee is full and unconditional, and the Operating Partnership is a consolidated subsidiary of the Company. Under Rule 3-10 of Regulation S-X, as amended, subsidiary issuers of obligations guaranteed by its parent company are not required to provide separate financial statements, provided that the subsidiary obligor is consolidated into the parent company's consolidated financial statements, the parent guarantee is "full and unconditional" and, subject to certain exceptions, the alternative disclosure required by Rule 13-01 is provided, which includes narrative disclosure and summarized financial information. Accordingly, separate consolidated financial statements of the Operating Partnership have not been presented. Furthermore, as permitted under Rule 13-01(a)(4)(vi), we have excluded the summarized financial information for the Operating Partnership as the assets, liabilities, and results of operations of the Operating Partnership are not materially different from the corresponding amounts presented in our consolidated financial statements and management believes such summarized financial information would be repetitive and not provide incremental value to investors.

Line of Credit

The Operating Partnership (as borrower), SUI (as guarantor), and certain lenders are parties to a credit agreement which governs our senior credit facility.


69
SUN COMMUNITIES, INC.
Prior to March 2024, the aggregate amount of our senior credit facility was $4.2 billion with the ability to upsize the total borrowings by an additional $800.0 million, subject to certain conditions. The aggregate amount under the senior credit facility consisted of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, pound sterling, euros, Canadian dollars and Australian dollars, subject to certain limitations. The maturity date of the revolving loan facility is April 7, 2026. At our option that maturity date may be extended two additional six-month periods.

In March 2024, we terminated the term loan facility and settled the associated $1.1 billion of borrowings outstanding under the term loan by increasing our borrowings under the revolving loan of the senior credit facility. By terminating the term loan, we reduced our aggregate borrowing capacity under the senior credit facility to $3.05 billion under the revolving loan. During the three months ended March 31, 2024, we recognized a Loss on extinguishment of debt in our Consolidated Statements of Operations of $0.6 million related to the termination of the term loan facility. In June 2024, we amended the senior credit facility to replace the Canadian Dollar Offered Rate with the Canadian Overnight Repo Rate Average ("CORRA") as the benchmark rate for borrowings denominated in Canadian dollars, with no other significant changes to the terms of the senior credit facility.

The senior credit facility bears interest at a floating rate based on the Adjusted Term Secured Overnight Financing Rate ("SOFR"), the Adjusted Eurocurrency Rate, the Australian Bank Bill Swap Bid Rate ("BBSY"), the Daily Sterling Overnight Index Average ("SONIA") Rate or the CORRA, as applicable, plus a margin, in all cases, which can range from 0.725% to 1.6%, subject to certain adjustments. As of December 31, 2024, the margins based on our credit ratings were 0.85% on the revolving loan facility.

At the lenders' option, the senior credit facility will become immediately due and payable upon an event of default under the Credit Facility Agreement. We had $1.4 billion and $944.1 million of borrowings outstanding under the revolving loan as of December 31, 2024 and 2023, respectively. The balance is recorded in Unsecured debt on the Consolidated Balance Sheets.

The senior credit facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the senior credit facility, but does reduce the borrowing amount available. We had $11.5 million and $26.2 million outstanding letters of credit at December 31, 2024 and 2023, respectively.

Financial Covenants

Pursuant to the terms of the senior credit facility, we are subject to various financial and other covenants. The most restrictive financial covenants for the senior credit facility are as follows:

CovenantRequirement
As of December 31, 2024
Maximum leverage ratio<65.0%32.0%
Minimum fixed charge coverage ratio>1.402.86
Maximum secured leverage ratio<40.0%11.9%

In addition, we are required to maintain the following covenants with respect to the senior unsecured notes payable:

CovenantRequirement
As of December 31, 2024
Total debt to total assets≤60.0%38.8%
Secured debt to total assets≤40.0%17.2%
Consolidated income available for debt service to debt service≥1.504.28
Unencumbered total asset value to total unsecured debt≥150.0%366.3%

As of December 31, 2024, we were in compliance with the above covenants and do not anticipate that we will be unable to meet these covenants in the near term.

Derivative Transactions

We enter into treasury rate lock contracts, interest rate swaps, and forward swaps for interest rate risk management purposes. We do not enter into derivative instruments for speculative purposes. The risks being hedged are the interest rate risk related to outstanding floating rate debt and forecasted debt issuance transactions, and the benchmark interest rates used are the SOFR and the SONIA Rate.


70
SUN COMMUNITIES, INC.
During the year ended December 31, 2024, we entered into five interest rate swap contracts with an aggregate notional value of $150.0 million to hedge interest rate risk associated with a future debt offering.

During the year December 31, 2024, in connection with the issuance of the 2029 Notes, we settled seven forward swap contracts totaling $255.0 million and paid a net settlement payment of $2.3 million to several counterparties. Refer to Note 14, "Derivative Financial Instruments," in our accompanying Consolidated Financial Statements for additional information.

Long-term Financing and Capital Requirements

Long-term Financing

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, expansion, and development of properties, other nonrecurring capital improvements and Operating Partnership unit redemptions through long-term unsecured and secured debt and the issuance of certain debt or equity securities subject to market conditions. If current market and economic conditions, including relating to, among other things, interest rates, currency fluctuations, equity valuations, and inflation, continue or worsen, our ability to obtain debt and equity capital in the long term on attractive terms may be adversely affected.

As of December 31, 2024, we had unrestricted cash on hand of $47.4 million, $1.6 billion of remaining capacity on the senior credit facility, and a total of 508 unencumbered MH, RV, marina, and UK properties.

From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, issue unsecured notes, obtain other debt financing or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the MH, RV, and marina industries at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those markets could make borrowing more difficult to secure, more expensive or effectively unavailable. In the event our current credit ratings are downgraded, it may become difficult or more expensive to obtain additional financing or refinance existing unsecured debt as maturities become due. Refer to "Risk Factors" in Part I, Item 1A of this Annual Report on Form 10-K. If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

As of December 31, 2024, our net debt to enterprise value was 30.9% (assuming conversion of all common and preferred OP units to shares of common stock). Our debt has a weighted average interest rate of 4.09% and a weighted average years to maturity of 6.2.

Capital Requirements

Our capital requirements as of December 31, 2024 include both short and long term obligations:

Our primary long-term liquidity needs are principal payments on outstanding debt as summarized in the table below:

SIGNIFICANT ACCOUNTING POLICIES AND CRITICAL ACCOUNTING ESTIMATES

Critical Accounting Estimates

Our Consolidated Financial Statements are prepared in accordance with United States of America generally accepted accounting principles, which require the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and resulting balances are reasonable; however, due to inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

Our significant accounting estimates include acquisitions of investment properties, impairments of long-lived assets, and impairments of goodwill. Refer to Note 1, "Significant Accounting Policies," in our accompanying Consolidated Financial Statements for information regarding our critical accounting estimates that affect the Consolidated Financial Statements and that use judgments and assumptions. In certain situations, we discuss the likelihood that materially different amounts could be reported under varied conditions and assumptions.

Goodwill Impairment

In performing goodwill impairment testing, we utilize a third-party valuation specialist to assist management in determining the fair value of our reporting units. The fair value of each reporting unit is estimated based on a combination of discounted cash flows (income approach) and the use of pricing multiples derived from an analysis of comparable public companies multiplied against historical and / or anticipated financial metrics (market approach) for each reporting unit. These calculations contain uncertainties as they require management to make assumptions including, but not limited to, market comparables, future cash flows of the reporting units, and appropriate weighted average cost of capital and long-term growth rates. A decline in the actual cash flows of our reporting units in future periods, as compared to the projected cash flows used in our valuations, could result in the carrying value of the reporting units exceeding their respective fair values. Further, a change in market comparables, discount rate or long-term growth rates, as a result of a change in economic conditions or otherwise, could result in the carrying values of the reporting units exceeding their respective fair values. Refer to Note 6, "Goodwill and Other Intangible Assets," in our accompanying Consolidated Financial Statements for additional information regarding goodwill.

In 2024 and 2023, we performed qualitative and quantitative assessments of our goodwill balance for potential impairment in accordance with ASC 350-20, "Intangibles - Goodwill and Other." As a result of our impairment testing, we determined that the fair value of the Park Holidays reporting unit within the UK reporting segment was below its carrying value in each such year and recorded non-cash goodwill impairment charges of $180.8 million and $369.9 million during the years ended December 31, 2024 and 2023, respectively. The declines in the fair value of the Park Holidays reporting unit were primarily driven by uncertainty in the macroeconomic environment in the region, which began in 2023 and was exacerbated by political changes during the fourth quarter of 2024, leading to a higher weighted average cost of capital, inflationary pressures and changing competitive market dynamics. The uncertainty in the macroeconomic and competitive landscape has caused a decline in projected future cash flows for our Park Holidays business that operates in the region. As a result of the recognized goodwill impairment charges, our goodwill balance at the UK reporting segment is now zero as of December 31, 2024.

Our other reporting units are less sensitive to changes in macroeconomic factors and forecast assumptions than our UK reporting unit due to greater excess of fair value over carrying value. For the Marina reporting unit, we concluded that the fair value exceeded its carrying value by over 7% as part of our annual testing during the fourth quarter of 2024. We did not identify a triggering event in any other reporting unit.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency exchange rates, commodity prices and equity prices.

Interest Rate Risk

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs and interest expense while continuously evaluating all available debt and equity resources, and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability that interest rate changes could have on our future cash flows. From time to time, we employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes.

Our variable rate debt totaled $635.5 million and $1.3 billion as of December 31, 2024 and 2023, respectively, after adjusting for the impact of hedging in place through the use of interest rate swaps. As of December 31, 2024 and 2023, our variable debt bore interest at the Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Australian BBSY rate, the Daily SONIA Rate or the CORRA, and the Eurodollar rate or Prime rate plus a margin. If the above rates increased or decreased by 1.0%, our interest expense would have increased or decreased by $8.1 million and $13.8 million for the years ended December 31, 2024 and 2023, respectively, based on the $811.1 million and $1.4 billion average balances outstanding under our variable rate debt facilities, respectively. Our variable rate debt, interest expense, and average balance outstanding under our variable rate debt facility includes the impact of hedge activity.

Foreign Currency Exchange Rate Risk

Foreign currency exchange rate risk is the risk that fluctuations in currencies against the U.S. dollar will negatively impact our results of operations. We are exposed to foreign currency exchange rate risk as a result of remeasurement and translation of the assets and liabilities of our properties in the UK and Canada, and our joint venture in Australia, into U.S. dollars. Fluctuations in foreign currency exchange rates can therefore create volatility in our results of operations and may adversely affect our financial condition.

At December 31, 2024 and 2023, our shareholder's equity included $672.3 million and $893.9 million from our investments and operations in the UK, Canada, and Australia, which collectively represented 9.3% and 12.5% of total shareholder's equity, respectively. Based on our sensitivity analysis, a 10.0% strengthening of the U.S. dollar against the pound sterling, Canadian dollar and Australian dollar would have caused a reduction of $67.2 million and $89.4 million to our total shareholder's equity at December 31, 2024 and 2023, respectively.

Capital Market Risk

We are exposed to risks related to the equity capital markets, and our related ability to raise capital through the issuance of our common stock or other equity instruments. We are also exposed to risks related to the debt capital markets, and our related ability to finance our business through borrowings under other financing arrangements. As a REIT, we are required to distribute a significant portion of our taxable income annually, which constrains our ability to accumulate operating cash flow and therefore requires us to utilize debt or equity capital to finance our business. We seek to mitigate these risks by monitoring the debt and equity capital markets to inform our decisions on the amount, timing and terms of capital we raise.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Annual Report was made under the supervision and with the participation of our management, including our principal executive officer and principal financial officer.

Based upon this evaluation, our principal executive officer and principal financial officer have concluded that, as of December 31, 2024, our disclosure controls and procedures were not effective as of that date due to a material weakness in internal control over financial reporting relating to our risk assessment process, as described below.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with GAAP. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, misstatements due to error or fraud may not be prevented or detected on a timely basis.

Our management performed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2024, utilizing the criteria discussed in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The objective of this assessment was to determine whether our internal control over financial reporting was effective as of December 31, 2024. Based on management's assessment, we have concluded that our internal control over financial reporting was ineffective as of December 31, 2024, due to the material weakness relating to our risk assessment process described below.

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 our annual or interim financial statements will not be prevented or detected on a timely basis.

Material Weakness - Risk Assessment and Response

As of December 31, 2024, we had a material weakness because we did not have an effective risk assessment and response process ("risk assessment") that defined clear financial reporting objectives, that identified and evaluated risks of misstatement due to errors over certain financial reporting processes, or that developed internal controls to mitigate those risks. As part of management's evaluation of this material weakness, it has been identified that certain other deficiencies in control activities have materialized as a result of the deficiency in the Company's risk assessment. Specifically, as of December 31, 2024, there are deficiencies in the design and implementation of the Company's internal controls due to ineffective risk assessment resulting in the following:

•Inadequate identification and timely consideration of accounting for certain transactions.
•Existence of inappropriate access and insufficient segregation of duties ("SOD") upon implementation of a new integrated enterprise resource planning and general ledger ("ERP") system during 2024.
•Reliance on information and reports from our new ERP used in internal controls over financial reporting without adequately validating their completeness and accuracy.
•Inadequate assessment of the impact our new ERP had on certain processes and related control activities, including investment property, inventory of manufactured homes, and the review and approval of manual journal entries.

These deficiencies relate to both information technology general controls, manual controls, and manual controls dependent upon information technology that could impact the consistency, timeliness and accuracy of financial reporting in accordance with GAAP. These matters did not result in material misstatements to the Consolidated Financial Statements in the current period, but do allow for the reasonable possibility that material misstatements would not be prevented or detected on a timely basis.


75
SUN COMMUNITIES, INC.
Plan for Remediation of the Material Weakness

We have invested considerable time and resources to undertake a number of actions related to the material weakness relating to our risk assessment process and we are in the process of developing and implementing additional actions as part of a detailed plan for remediation. The Audit Committee has continued to actively oversee these remediation plans, monitoring plan progression and ensuring appropriate resources are allocated and implemented to effectively execute management's plan. The actions that we have undertaken are as follows:

•Implemented more frequent communication between those charged with governance and management regarding progression on material weakness remediation. Additionally, an internal control project plan was developed and has begun to be implemented under the monitoring and supervision of the Audit Committee.
•Engaged a third-party accounting and advisory firm to assist us with completing a comprehensive risk assessment and a gap analysis of certain aspects of our risk control matrix, including identification of risks of material misstatement, to assess the potential need for any new controls or controls that need to be redesigned to adequately address the corresponding financial reporting risk.
•Completed a risk-based review of user access to our ERP and when necessary modified roles or user access to eliminate SOD conflicts. We engaged a third-party accounting and advisory firm to confirm the scope and execution of this access review.
•Implemented a third-party software solution to assist management with monitoring user access to our ERP system to identify and prevent user access that violates our established SOD ruleset.
•Identified a complete population of information and reports used in internal controls over financial reporting and began validating the completeness and accuracy of this information and reports generated from our new ERP.

Additionally, management's detailed plan for remediation includes the following:

•Redesigning the review control related to certain manual journal entries.
•Ensuring internal control processes include policies and procedures to ensure that all information used in the performance of internal controls is validated for completeness and accuracy.
•Redesigning or developing new internal controls to address risks, if any, determined to not be adequately mitigated following the completion of the risk assessment and gap analysis currently in process.
•Refining and developing additional SOD rules as needed based on the results of the review of our SOD ruleset by the third-party accounting and advisory firm.

While we believe our remediation efforts above will improve the effectiveness of our internal control over financial reporting, we cannot assure that the measures will be sufficient to remediate the material weakness we have identified or will prevent potential future material weaknesses. In addition, many of the improvements have not operated for a sufficient period of time to be able to conclude on the effectiveness of relevant internal controls. Accordingly, we will continue to monitor, with oversight from our Board of Directors, and evaluate the effectiveness of our internal control over financial reporting and further enhance our plan for remediation as necessary.

Remediation of Previously Disclosed Material Weaknesses

We previously identified and disclosed in Part II, Item 9A, "Controls and Procedures" of our Annual Report on Form 10-K for the year ended December 31, 2023, a material weakness related to the design of management's review controls of potential triggering events related to the evaluation for impairment of goodwill relating to our Park Holidays reporting unit within the UK reporting segment. During 2024 the goodwill at the UK reporting segment was fully impaired. The Company has concluded that there is no longer a risk of material misstatement related to this management review control.

We also previously identified and disclosed in Part I, Item 4, "Controls and Procedures" of our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2024, a material weakness related to the design of management's review controls for evaluating long-lived assets for impairment, relating to certain long-lived asset groupings and properties within the UK reporting segment. As of December 31, 2024, we determined that this previously reported material weakness is a result of the risk assessment material weakness described above and will be covered by the remediation activities described above.

SUN COMMUNITIES, INC.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
Sun Communities, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the "Company") as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income, changes in shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes and financial statement schedule included under Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"), and our report dated February 28, 2025 expressed an adverse opinion.

Basis for opinion
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Potential Impairment of Investment Properties
As described further in Note 1 to the consolidated financial statements, the Company reviews the carrying value of its long-lived assets, which includes its investment properties, for impairment on a quarterly basis or whenever events or changes in circumstances indicate a possible impairment. Events or circumstances that may prompt a test of recoverability may include a significant decrease in the anticipated market price, and adverse change to the extent or manner in which an asset may be used or in its physical condition or other events that may significantly change the value of the long-lived asset.

The Company reviews investment properties for potential impairment and if any impairment indicators are identified, the Company undertakes additional analyses utilizing expected undiscounted future cash flows for identified investment properties. Forecasting of cash flows requires management to make estimates and assumptions about variables such as growth rates, forecasted net operating income, estimated holding period, development and operating expenses during the holding period, and capitalization rates.

We identified the evaluation of recoverability of investment properties when an impairment indicator is identified as a critical audit matter.


F - 2
SUN COMMUNITIES, INC.
The principal consideration for our determination that the evaluation of recoverability of investment properties is a critical audit matter is that auditing management's evaluation of impairment is challenging due to the high degree of subjective auditor judgment necessary in evaluating management's determination of undiscounted cash flows for properties where impairment indicators have been identified. The significant assumptions used in the undiscounted cash flows analysis includes growth rates, forecasted net operating income, estimated holding period, and capitalization rates. These assumptions can be affected by expectations about future market or economic conditions, demand and competition.

Our audit procedures related to evaluating management's determination of undiscounted cash flows for properties where impairment indicators have been identified included the following, among others:

•We evaluated the design and tested the operating effectiveness of the controls that address the evaluation of recoverability, including management's review of the operations and financial performance of investment properties and preparation of undiscounted cash flow analysis.

•When an undiscounted cash flow analysis was necessary, we evaluated the significant assumptions and methods used in developing that analysis. As part of our evaluation, for certain investment properties we assessed the historical accuracy of the Company's estimates and ability to forecast property performance. We also performed sensitivity analyses of certain significant assumptions to evaluate the changes in the undiscounted cash flows of certain properties that would result from changes in the assumptions used by management.

•We utilized an internal valuation specialist to compare the consistency of capitalization rates used by the Company to those used for comparable properties in the market.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
Sun Communities, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the "Company") as of December 31, 2024, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). In our opinion, because of the effect of the material weakness described in the following paragraphs on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2024, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

A material weakness is a deficiency, or combination of control 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. The following material weakness has been identified and included in management's assessment.

The Company has identified a deficiency in a principle associated with the risk assessment component of the COSO framework. Specifically, the control deficiency constitutes a material weakness relating to defining clear financial reporting objectives, that identify and evaluate risks of misstatements due to errors over certain financial reporting processes, or the development of internal controls to mitigate those risks. The risk assessment and response material weakness contributed to other deficiencies in the design and implementation of the Company's internal control:

•Inadequate identification and timely consideration of accounting for certain transactions.

•Existence of inappropriate access and insufficient segregation of duties upon implementation of a new integrated enterprise resource planning ("ERP") and general ledger system during 2024.

•Reliance on information and reports from the Company's ERP used in internal controls over financial reporting without adequately validating their completeness and accuracy.

•Inadequate assessment of the impact of the Company's new ERP on certain processes and related control activities, including investment property, inventory of manufactured homes, and the review and approval of manual journal entries.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated financial statements of the Company as of and for the year ended December 31, 2024. The material weakness identified above was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2024 consolidated financial statements, and this report does not affect our report dated February 28, 2025 which expressed an unqualified opinion on those financial statements.

Basis for opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting
A company's 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 for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Significant Accounting Policies

Business

Sun Communities, Inc., a Maryland corporation, 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., a Michigan corporation ("SHS"), Safe Harbor Marinas, LLC, a Delaware limited liability company ("Safe Harbor") and our Park Holidays subsidiaries and the other entities through which we operate our business in the United Kingdom ("UK") are referred to herein as the "Company," "SUI," "us," "we," or "our."

We are a fully integrated, self-administered and self-managed REIT. As of December 31, 2024, we owned and operated or had an interest in, a portfolio of 645 MH and RV communities and marinas (collectively, the "properties") located in the U.S., Canada, and the UK, including 288 MH communities, 166 RV communities, 138 marinas, and 53 UK communities.

Principles of Consolidation

We consolidate our majority-owned subsidiaries in which we have the ability to control the operations of our subsidiaries and all variable interest entities with respect to which we are the primary beneficiary. We also consolidate entities in which we have a direct or indirect controlling or voting interest. All significant intercompany transactions have been eliminated in consolidation. Any subsidiaries in which we have an ownership percentage equal to or greater than 50%, but less than 100%, or are considered to be a consolidated VIE, represent subsidiaries with a non-controlling interest. The noncontrolling interests in our subsidiaries are allocated their proportionate share of the subsidiaries' financial results. Certain reclassifications have been made to prior period financial statements in order to conform to current period presentation. There was no impact to prior period net income for any of the reclassifications.

We consolidate the Operating Partnership under the guidance set forth in ASC 810, "Consolidation." We evaluated whether the Operating Partnership met the criteria for classification as a variable interest entity ("VIE") or, alternatively, as a voting interest entity and concluded that the Operating Partnership met the criteria of a VIE. Our significant asset is our investment in the Operating Partnership, and consequently, substantially all of our assets and liabilities represent those assets and liabilities of the Operating Partnership. We are the sole general partner and generally have the power to manage and have complete control over the Operating Partnership and the obligation to absorb its losses or the right to receive its benefits.

Total assets related to consolidated VIEs, with the exception of the Operating Partnership, comprised 0.6% and 0.8% of our consolidated total assets at December 31, 2024 and 2023, respectively. Total liabilities comprised less than 1.0% of our consolidated total liabilities at December 31, 2024 and 2023. Equity Interests and Noncontrolling interests related to the consolidated VIEs, on an absolute basis, comprised less than 1.0% of our consolidated total equity at December 31, 2024 and 2023.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions related to the reported amounts included in our Consolidated Financial Statements and accompanying footnotes thereto. Actual results could differ from those estimates.

Investment Property

Investment property is recorded at cost, less accumulated depreciation.

Impairment of long-lived assets - we review the carrying value of long-lived assets to be held for use for impairment quarterly or whenever events or changes in circumstances indicate a possible impairment. Future events could occur which would cause us to conclude that impairment indicators exist, and significant adverse changes in national, regional, or local market conditions or trends may cause us to change the estimates and assumptions used in our impairment analysis. The results of an impairment analysis could be material to our financial statements. Our primary indicator for potential impairment is based on NOI trends period over period. Circumstances that may prompt a test of recoverability may include a significant decrease in the anticipated market price, an adverse change to the extent or manner in which an asset may be used or in its physical condition or other events that may significantly change the value of the long-lived asset. An impairment loss is recognized when a long-lived asset's carrying value is not recoverable and exceeds estimated fair value.


F - 12
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
We estimate the fair value of our long-lived assets based on discounted future cash flows and any potential disposition proceeds for a given asset. Forecasting cash flows requires management to make estimates and assumptions about such variables as the estimated holding period, rental rates, occupancy, development and operating expenses during the holding period, as well as capitalization rates. Management uses its best judgment when developing these estimates and assumptions.

Real estate held for sale - we periodically classify real estate as held for sale. An asset is classified as held for sale after an active program to sell an asset has commenced and when the sale is probable. Subsequent to the classification of assets as held for sale, no further depreciation expense is recorded. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional information regarding real estate assets held for sale as of December 31, 2024.

Acquisitions - we evaluate acquisitions pursuant to ASC 805, "Business Combinations," to determine whether the acquisition should be classified as either an asset acquisition or a business combination.

Acquisitions for which substantially all of the fair value of the gross assets acquired are concentrated in a single identifiable asset or a group of similar identifiable assets are accounted for as an asset acquisition. The majority of our property acquisitions are accounted for as asset acquisitions. For asset acquisitions, we allocate the purchase price of these properties on a relative fair value basis and capitalize direct acquisition related costs as part of the purchase price. Acquisition costs that do not meet the criteria to be capitalized are expensed as incurred and presented as General and administrative costs in our Consolidated Statements of Operations.

Acquisitions that meet the definition of a business combination are recorded at fair value using a fair value model under which the assets and liabilities are generally recognized at their fair values and the difference between the consideration transferred, excluding transaction costs, and the fair values of the assets and liabilities is recognized as goodwill. For acquisitions that meet the definition of a business combination, we allocate the purchase price of those properties on a fair value basis and expense the acquisition related transaction costs as incurred. Transaction costs are presented as Business combinations expense in our Consolidated Statements of Operations.

For asset acquisitions and business combinations, we allocate the purchase price to net tangible and identified intangible assets acquired based on their fair values. In making estimates of fair values for purposes of allocating purchase price, we utilize an independent third party to value the net tangible and identified intangible assets in connection with the acquisition of the respective property. We provide historical and pro forma financial information obtained about each property, as well as any other information needed in order for the third party to ascertain the fair value of the tangible and intangible assets acquired.

Capitalized Costs

We capitalize certain costs incurred in connection with the development, redevelopment, capital enhancement and leasing of our properties. Management is required to use professional judgment in determining whether such costs meet the criteria for capitalization or immediate expense. The amounts are dependent on the volume and timing of such activities, and the costs associated with such activities:

•Maintenance, repairs, and minor improvements to properties are expensed when incurred.
•Renovations and improvements to our properties are capitalized and depreciated over their estimated useful lives and real estate project costs related to the development of new community or expansion sites are capitalized until the property is substantially complete and available for occupancy.
•Costs incurred to initially renovate pre-owned and repossessed homes that we acquire for our Rental Program are capitalized, and the majority of costs incurred to refurbish the homes at turnover and repair the homes while occupied, are expensed unless they extend the life of the home.
•Renovations and improvements to marinas are capitalized and depreciated over their estimated useful lives.
•Improvements made to docks, buildings, systems, equipment, shorelines, and site improvements are capitalized until the project is substantially complete and available for use.
•Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized based on the anticipated term of occupancy of a resident.
•Costs incurred to develop internal-use software are capitalized and amortized on a straight-line basis over the estimated useful life of the related software (typically one to eight years).
•Costs associated with purchases of furniture, fixtures and equipment, major replacements, and improvements are capitalized and subsequently depreciated over their respective underlying assets estimated useful lives.

F - 13
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
•Costs incurred to obtain new debt financing (i.e. deferred financing costs) are capitalized and amortized over the term of the underlying loan agreement using the effective interest method for senior unsecured notes and the straight-line method (which approximates the effective interest method) for other financing. Deferred financing costs include fees and costs incurred to obtain long-term financing. Unamortized deferred financing costs are written off when debt is retired before the maturity date. Upon amendment of the line of credit or refinancing of mortgage debt, unamortized deferred financing costs and any related discounts or premiums are accounted for in accordance with ASC 470-50-40, "Modifications and Extinguishments."

Cash and Cash Equivalents

We consider all highly liquid investments with a maturity of three months or less from the date of purchase to be cash and cash equivalents. At December 31, 2024 and 2023, $47.4 million and $29.2 million of cash and cash equivalents, respectively, was included as a component of Cash, cash equivalents and restricted cash on the Consolidated Balance Sheets. The maximum amount of credit risk arising from cash deposits in excess of federally insured amounts was approximately $46.4 million and $45.6 million as of December 31, 2024 and 2023, respectively. The maximum amount of credit risk arising from UK's cash deposits in excess of insured amounts through the Financial Services Compensation Scheme ("FSCS") was approximately £0.8 million ($1.0 million) and £1.8 million ($2.3 million) as of December 31, 2024 and 2023, respectively.

Restricted Cash

Restricted cash consists primarily of utility deposits and amounts held in deposit for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. At December 31, 2024 and 2023, $16.4 million and $13.5 million of restricted cash, respectively, was included as a component of Cash, cash equivalents and restricted cash on the Consolidated Balance Sheets. Changes in the restricted cash are reported in our Consolidated Statements of Cash Flows as operating, investing or financing activities based on the nature of the underlying activity. Restricted cash and restricted cash equivalents are included with cash and cash equivalents in the reconciliation of the beginning of period and the end of period cash balance on the Consolidated Statements of Cash Flows.

Inventory

Inventory of manufactured homes is stated at lower of specific cost or net realizable value based on the specific identification method and the balance is separately disclosed on our Consolidated Balance Sheets. Other inventory at our MH and RV properties consists primarily of service and merchandise related items, grocery, food, and beverage products and are stated at the lower of cost or net realizable value. Physical inventory counts are performed where inventory exists. Inventory records are adjusted accordingly to reflect actual inventory counts and any resulting shortage is recognized. Inventory at our marinas consists primarily of boats for sale at certain marinas, boat parts used in our service centers and retail related items such as merchandise used in our ship stores, gasoline and diesel fuel, and food and beverage products. Inventories at our marinas are stated at the lower of cost or net realizable value with cost determined using the First In, First Out ("FIFO") method. Physical inventory counts are performed where inventory exists. Inventory records are adjusted accordingly to reflect actual inventory counts and any resulting shortage is recognized. The other inventory balance is included in Other assets, net on our Consolidated Balance Sheet.

Investments in Nonconsolidated Affiliates

We apply the equity method of accounting to entities in which we do not have a direct or indirect controlling interest or for variable interest entities where we are not considered the primary beneficiary but can exercise significant influence over the entity with respect to its operations and major decisions. Under the equity method of accounting, the cost of an investment is adjusted for our share of the equity in net income or loss from the date of acquisition, reduced by distributions received and increased by contributions made. The income or loss of each entity is allocated in accordance with the provisions of the applicable operating agreements. The allocation provisions in these agreements may differ from the ownership interests held by each investor. Our exposure to losses associated with nonconsolidated affiliates is primarily limited to the carrying value of these investments. Accordingly, distributions from a nonconsolidated affiliate in excess of our carrying value are recognized in earnings. We review the carrying value of our investments in nonconsolidated affiliates for other than temporary impairment whenever events or changes in circumstances indicate a possible impairment. Financial condition, operational performance and other economic trends are among the factors we consider when we evaluate the existence of impairment indicators. Refer to Note 7, "Investments in Nonconsolidated Affiliates," for additional information.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Notes and Other Receivables

Notes receivable - includes installment loans for manufactured homes purchased from us, transferred loans that have not met the requirements for sale accounting which are presented herein as collateralized receivables, and notes receivable from real estate developers and operators. The installment notes receivable and collateralized receivables are collateralized by the underlying manufactured home sold.

Collateralized receivables - represent transferred loans that have not met the requirements for sale accounting under ASC 860, "Transfers and Servicing."

Installment notes receivable on manufactured homes - represent notes receivable for the purchase of manufactured homes primarily located in our communities, which are secured by the underlying manufactured home sold. Interest income is accrued based on the unpaid principal balance of the loans. Past due status of our notes receivable is determined based on the contractual terms of the note. When a note receivable becomes 60 days delinquent, we stop accruing interest on the note receivable. The interest on nonaccrual loans is accounted for on the cash basis until qualifying for return to accrual.

Notes receivable from real estate developers and operators - represent short-term construction loans provided to real estate developers and loans provided to a real estate operator to finance acquisition and development costs.

We elected to fair value our installment notes receivable on manufactured homes, collateralized receivables and notes receivable from real estate developers and operators in accordance with ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("CECL"). Installment notes receivable on manufactured homes and notes receivable from real estate developers and operators are measured at fair value pursuant to FASB ASC 820, "Fair Value Measurements and Disclosures." The fair value is evaluated quarterly, and any fair value adjustments are recorded in Loss on remeasurement of notes receivable on the Consolidated Statement of Operations. Refer to Note 15, "Fair Value Measurements," for additional information regarding the estimates and assumptions used to estimate the fair value of each financial instrument class.

Other receivables - are generally comprised of sale proceeds receivable from home sales near year end, amounts due from marina customers for storage, service and lease payments, amounts due from MH, annual RV, and UK residents for rent, and related charges (utility charges, fees, and other pass-through charges), insurance receivables and various other miscellaneous receivables. Accounts outstanding longer than the contractual payment terms are considered past due.

Accounts receivable from marina customers are stated at amounts due net of an allowance for credit losses. Receivables related to our marina rents are reserved when we believe that collection is less than probable, which is generally 50% for certain receivable balances over 180 days, and 60% after the balance reaches 60 days past due for all other receivables.

Accounts receivable from residents are typically due within 30 days and stated at amounts due from residents net of an allowance for credit losses. We evaluate the recoverability of our receivables whenever events occur or there are changes in circumstances such that management believes it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan and lease agreements. Receivables related to MH community rents are reserved when we believe that collection is less than probable, which is generally after a resident balance reaches 60 to 90 days past due. In the UK, annual rents are noticed in full during the fourth quarter and due by January 31st of the following year. Payment can be made upfront or in monthly installments. Accounts receivables are reviewed regularly for collectability, with related reserves set annually for outstanding receivables. Refer to Note 4, "Notes and Other Receivables," for additional detail on receivables.

Goodwill

We account for goodwill pursuant to ASC 350, "Intangibles—Goodwill and Other." Goodwill is tested for impairment at the reporting unit level. If the fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. We assess our goodwill for impairment on an annual basis, or more frequently if events or changes in circumstances arise and impairment indicators are identified. Events or circumstances that may result in an impairment review include changes in macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events, specific events affecting the reporting unit or a sustained decrease in share prices. Estimating the fair value of individual reporting units requires us to make assumptions and estimates regarding industry, economic, and regulatory conditions in each respective geographic region in which we conduct operations.


F - 15
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
In performing goodwill impairment testing, we utilize a third-party valuation specialist to assist management in determining the fair value of our reporting units. The fair value of each reporting unit is estimated based on a combination of discounted cash flows (income approach) and the use of pricing multiples derived from an analysis of comparable public companies multiplied against historical and / or anticipated financial metrics (market approach) for each reporting unit. These calculations contain uncertainties as they require management to make assumptions including, but not limited to, market comparables, future cash flows of the reporting units, and appropriate weighted average cost of capital and long-term growth rates. A decline in the actual cash flows of our reporting units in future periods, as compared to the projected cash flows used in our valuations, could result in the carrying value of the reporting units exceeding their respective fair values. Further, a change in market comparables, discount rate or long-term growth rates, as a result of a change in economic conditions or otherwise, could result in the carrying values of the reporting units exceeding their respective fair values.

During the year ended December 31, 2024, we performed goodwill impairment assessments. For the Park Holidays reporting unit within the UK reporting segment, we recorded aggregate impairment charges of $180.8 million to write down the carrying value to its respective fair value. In 2024 and 2023, we performed qualitative and quantitative assessments of our goodwill balance for potential impairment. As a result of our impairment testing, we determined that the fair value of the Park Holidays reporting unit was below its carrying value in each year and recorded non-cash goodwill impairment charges of $180.8 million and $369.9 million during the years ended December 31, 2024 and 2023, respectively. Refer to Note 6, "Goodwill and Other Intangible Assets," for additional information on goodwill and goodwill impairment charges.

Goodwill is deductible for income tax purposes. As such, the goodwill portion allocated to our U.S. taxable REIT subsidiaries will reduce their taxable income. However, the resulting tax benefits will be offset by a valuation allowance. Given that REITs do not customarily report any taxable income (due to the dividends paid deduction), we do not expect any significant tax benefits arising from the goodwill allocable to the REIT. Goodwill allocated to the UK taxable REIT subsidiaries is not deductible for UK tax purposes resulting in no tax benefit in the UK. However, it will reduce their U.S. dividends to the REIT in the future.

Other Intangible Assets

Other intangible assets primarily comprise in-place leases (including slip in-place leases), non-competition agreements, trademarks and trade names, customer relationships, and franchise agreements. Other intangible assets are reviewed for impairment on an annual basis or more frequently if indicators of impairment are identified.

Intangible assets with finite lives - we amortize identified intangible assets that are determined to have finite lives over the period the assets are expected to contribute directly or indirectly to the future cash flows of the property or business. Intangible assets that are deemed to have finite lives are amortized on a straight line basis over their useful lives, which range from two months to 27 years.

Trademarks and trade names - we account for trademarks and trade names pursuant to ASC 350, "Intangibles-Goodwill and Other." Some trademarks and trade names have an indefinite useful life and some have a three to 15 year useful life. Trademarks and trade names with finite lives are amortized over their useful life. Trademarks and trade names with indefinite-lives are not amortized. Trademarks and trade names are reviewed for impairment on an annual basis or more frequently if indicators of impairment are identified.

We account for implementation costs in a hosting arrangement in accordance with ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)," which aligns requirements for capitalizing implementation costs in a hosting arrangement as a service contract with internally developed software, and expense capitalized costs of the hosting arrangement over the term of the arrangement.

The carrying amounts of the other identified intangible assets are included in Other intangible assets, net on our Consolidated Balance Sheets. Refer to Note 6, "Goodwill and Other Intangible Assets," for additional information on other intangible assets.

Deferred Taxes

We are subject to certain state taxes that are considered to be income taxes and have certain subsidiaries that are taxed as regular corporations for U.S. (i.e., federal, state, local, etc.) and non-U.S. income tax purposes. Deferred tax assets or liabilities are recognized for temporary differences between the tax basis of assets and liabilities and their carrying amounts in the financial statements and net operating loss carryforwards in certain subsidiaries, including those domiciled in foreign jurisdictions, which may be realized in future periods if the respective subsidiary generates sufficient taxable income. Deferred tax assets and liabilities are measured using currently enacted tax rates. A valuation allowance is established if, based on the available evidence, it is considered more likely than not that some portion or all of the deferred tax assets will not be realized. Refer to Note 12, "Income Taxes," for additional information.

Temporary Equity

Temporary equity includes preferred securities that are redeemable for cash at the holder's option or upon the occurrence of an event that is not solely within our control based on a fixed or determinable price. These securities are not mandatorily redeemable for cash nor do they contain a fixed maturity date. Temporary equity is classified between Liabilities and Shareholders' Equity on the Consolidated Balance Sheets.

Share-Based Compensation

We account for awards of restricted stock in accordance with ASC 718-10, "Compensation-Stock Compensation." ASC 718-10 requires that compensation cost for all stock awards be calculated and amortized over the service period (generally equal to the vesting period). The fair value of restricted stock awards with service vesting is equal to the fair value of our stock on the grant date. Share-based compensation cost for service vesting restricted stock awards is measured based on the closing share price of our common stock on the date of grant. We measure the fair value of awards with performance conditions based on an estimate of shares expected to vest using the closing price of our common stock as of the grant date. If it is not probable that the performance conditions will be satisfied, we do not recognize compensation expense. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation. We recognize compensation cost ratably over each tranche of shares based on the fair value estimated by the model. We also recognize related estimated award forfeitures ratably over each tranche of shares. We estimate forfeitures at the time of grant based on the historical turnover rate of employees and non-employees that are recipients of an award. We update our assumptions annually for the subsequent year awards. Refer to Note 10, "Share-Based Compensation," for additional information.

Fair Value Measurements

Our financial instruments consist primarily of cash, cash equivalents and restricted cash, notes and other receivables, derivative assets and liabilities, debt, and other liabilities. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to ASC 820, "Fair Value Measurements and Disclosures."

ASC 820, "Fair Value Measurements and Disclosures," requires disclosure regarding determination of fair value for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1 - Quoted unadjusted prices for identical instruments in active markets that we have the ability to access;

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable (e.g., interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) in active markets or can be corroborated by observable market data; and

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The unobservable inputs reflect our assumptions about the assumptions that market participants would use.

Refer to Note 15, "Fair Value Measurements," for additional information on methods and assumptions used to estimate the fair value of each financial instrument class.

Revenue Recognition

As a real estate owner and operator, the majority of our revenue consists of Income from real property from site and home leases and wet slip and dry storage space leases that are accounted for pursuant to ASC 842, "Leases." Other revenue streams, such as those generated from home sales and service, retail, dining, and entertainment activities, are accounted for pursuant to ASC 606, "Revenue from Contracts with Customers," except for those that are within the scope of other topics in the FASB ASC. For transactions in the scope of ASC 606, we recognize revenue when control of goods or services transfers to the customer, in the amount that we expect to receive for the transfer of goods or provision of services. Due to the nature and timing of our identified revenue streams, there were no material outstanding performance obligations as of December 31, 2024. Refer to Note 2, "Revenue," for additional information.

Income from real property includes revenue from residents and guests in our communities, who lease the site on which their home or RV is located and either own or lease their home or RV, rental home revenue, wet slip and dry storage space revenue at our marinas, and short-term vacation home and site rentals. Revenues from residents and guests includes revenues from site leases to annual MH residents and annual RV guests, and site rentals to transient RV guests. Resident leases are generally for one-year, but may range from month-to-month to two year terms and are renewable by mutual agreement between the parties, or in some cases, as provided by statute. The majority of our slip and storage space leases have annual terms that are generally billed seasonally and are renewable by mutual agreement between the parties. Revenues from site and home leases and wet slip and dry storage space leases fall under the scope of ASC 842, and are accounted for as operating leases with straight-line recognition. Non-lease components of our site lease contracts, which are primarily provision of utility services at our communities, are accounted for with the site lease as a single lease component per ASC 842. In accordance with the practical expedient criteria to combine lease and non-lease components, we noted that the timing and pattern of transfer for the lease and non-lease components are the same, and the leases qualify as operating leases. Accordingly, we present rental revenues and utility recoveries as a single lease component within Income from real property in the Consolidated Statement of Operations. Rental home revenues which comprise rental agreements whereby we lease homes to residents in our communities, and short-term vacation home and site rentals are accounted for under ASC 842. Additionally, we include collections of real estate taxes from residents and guests within Income from real property. As a lessor, we have a significant amount of variable lease payments that we receive, usually from revenue derived from percentage-based leases. The revenue from these leases is accounted for on an as earned basis. We also have a number of short-term leases that are accounted for on an as earned basis. All our revenues are recognized net of taxes collected from customers and submitted to taxing authorities. Real estate taxes are recorded as a liability when collected and released when payments are remitted to tax authorities.

Revenue from home sales - SHS, our U.S. taxable REIT subsidiary, and Park Holidays, sell manufactured homes to current and prospective residents in our communities. We recognize revenue from home sales pursuant to ASC 606 as manufactured homes are tangible personal property that can be located on any land parcel. Manufactured homes are not permanent fixtures or improvements to the underlying real estate and we therefore do not consider them to be subject to the guidance in ASC 360-20, "Real Estate Sales." In accordance with the core principle of ASC 606, we recognize revenue from home sales at the time of closing when control of the home transfers to the customer. After closing of the sale transaction, we have no remaining performance obligation. As of December 31, 2024 and 2023, we had $24.5 million and $28.2 million, respectively, of receivables from contracts with customers, which consists of home sales proceeds, and are presented as a component of Notes and other receivables, net on our Consolidated Balance Sheets. These receivables represent balances owed to us for previously completed performance obligations for sales of manufactured homes. We report real estate taxes collected from residents and remitted to taxing authorities in revenue.

Service, retail, dining and entertainment revenue - is primarily composed of proceeds from restaurant, golf, merchandise, retail, fuel, service and other activities at our RV communities, marinas, and MH communities in the U.K. Revenues are recognized at the point of sale when control of the good or service transfers to the customer and our performance obligation has been satisfied. In addition, Marina rental income, which includes boat rentals, is earned when the customer takes control of the good or service and is included in Service, retail, dining and entertainment revenue. Sales and other taxes that we collect concurrent with revenue-producing activities are excluded from the transaction price.

Interest income - is earned primarily on our notes receivable, which include installment notes receivables on manufactured homes purchased by us from loan originators and notes receivable from real estate developers and operators. Interest income on these receivables is accrued based on the unpaid principal balances of the underlying loans on a level yield basis over the life of the loans. Interest income is not in the scope of ASC 606. Refer to Note 4, "Notes and Other Receivables," for additional information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Brokerage commissions and other - comprise brokerage commissions for sales of manufactured homes at our communities and brokerage commissions at our marinas, where we act as agent and arrange for a third party to transfer a manufactured home, a park model or a boat to a customer within one of our properties. Brokerage commission revenues are accounted for in accordance with ASC 606 and are recognized on a net basis at closing, when the transaction is completed and our performance obligations have been fulfilled. Other revenues primarily include prepaid rent adjustments, proceeds from business interruption insurance, dividend income and management fees earned from managing third-party-owned holiday parks and third-party-owned marinas.

Advertising Costs

Advertising costs are expensed as incurred. As of December 31, 2024, 2023, and 2022, we had advertising costs of $34.1 million, $33.8 million and $30.9 million, respectively.

Depreciation and Amortization

Foreign Currency

The assets and liabilities of our operations in the UK, Canada, and Australia, where the functional currency is the pound sterling, Canadian dollar and Australian dollar, respectively, are translated into U.S. dollars using the exchange rate in effect as of the balance sheet date. Income statement amounts are translated at the average exchange rate prevailing during the period. The resulting translation adjustments are recorded as a component of Accumulated other comprehensive income. Foreign currency exchange gains and losses arising from fluctuations in currency exchange rates on transactions and the effects of remeasurement of monetary balances denominated in currencies other than the functional currency are recorded in earnings within Gain / (loss) on foreign currency exchanges on the Consolidated Statements of Operations.

For the years ended, December 31, 2024, 2023, and 2022, we recorded a foreign currency exchange loss of $25.8 million, a loss of $0.3 million and a gain of $5.4 million, respectively, on our Consolidated Statements of Operations.

Derivative Instruments and Hedging Activities

We enter into derivative instruments for risk management purposes to minimize the effect of interest rate changes on future cash outflows related to outstanding floating rate debt and forecasted issuances of long-term debt, and the benchmark interest rates used are the SOFR and the SONIA Rate. Treasury rate lock contracts, interest rate swaps and forward swaps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
We recognize derivative instruments at fair value on a recurring basis on the Consolidated Balance Sheets and classify the derivatives within Level 2 of the fair value hierarchy. We adjust our Consolidated Balance Sheets on a quarterly basis to reflect the current fair market value of the derivative instruments. Refer to Note 15, "Fair Value Measurements," for additional information related to the fair value methodology used for derivative financial instruments.

As of December 31, 2024, all outstanding derivative instruments have been designated as cash flow hedges under ASC Topic 815, "Derivatives and Hedging." These contracts have maturities of 10 years or less. The risks being hedged are the interest rate risk related to outstanding floating rate debt and forecasted debt transactions. We assess the effectiveness of the derivative instruments in hedging the underlying interest rate exposure both at inception and on an ongoing basis. The unrealized gains or losses on the derivative instruments are recorded in Accumulated other comprehensive income and are reclassified to Interest expense on the Consolidated Statements of Operations during the same period in which the hedged transaction affects earnings. We estimate that $6.4 million will be reclassified as a reduction to Interest expense over the next 12 months for all of our outstanding cash flow hedges. Cash flow from these derivative instruments is classified in the same category as the cash flow items being hedged on the Consolidated Statements of Cash Flows. Refer to Note 14, "Derivative Financial Instruments," for additional information regarding derivative activity.

Accounting for Leases

Lessee Accounting

Pursuant to ASC Topic 842, "Leases," we determine if an arrangement is a lease at inception based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Our operating lease agreements are primarily for land and submerged land under non-cancelable operating leases at certain properties, executive office spaces and certain equipment leases. The ROU asset and liabilities are included within Other assets, net and Other liabilities on the Consolidated Balance Sheets.

For operating leases with a term greater than one year, we recognize the ROU assets and liabilities related to the lease payments on the Consolidated Balance Sheets. The lease liabilities are initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. The ROU assets represent our right to use the underlying assets for the term of the lease and the lease liabilities represent our obligation to make lease payments arising for the agreements. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred, less any lease incentives received, and any adjustments to reflect favorable or unfavorable terms of the lease when compared with market terms. The ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus unamortized initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Variable lease payments, except for the ones that depend on an index or rate, are excluded from the calculation of the ROU assets and lease liabilities and are recognized as variable lease expense in the Consolidated Statements of Operations in the period in which they are incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Many of our lessee agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. The lease liability costs are amortized over the straight-line method over the term of the lease. Operating leases with a term of less than one year are recognized as a lease expense over the term of the lease, with no asset or liability recognized on the Consolidated Balance Sheets.

Finance leases where we are the lessee are included in Investment property, net and Other liabilities on our Consolidated Balance Sheets. The lease liabilities are initially measured in the same manner as operating leases and are subsequently measured at amortized cost using the effective interest method. Refer to Note 17, "Leases," for information regarding leasing activities.

Lessor Accounting

Leases to Customers

As detailed in the Revenue Recognition section, our income from real property at our communities and marinas is derived from rental agreements where we are the lessor. ASC 842 limits the definition of initial direct costs to only the incremental costs of signing a lease. Internal sales employees' compensation, payroll-related fringe benefits, certain legal fees rendered prior to the execution of a lease, negotiation costs, advertising and other origination effort costs do not meet the definition of an initial direct cost and therefore, are accounted for as General and administrative expense or Property operating and maintenance expense in our Consolidated Statements of Operations. ASC 842 permits the capitalization of direct commission costs.

Fixed lease income from tenants is recognized on a straight-line basis over the terms of the relevant lease agreement and is included within Income from real property and Brokerage commissions and other revenue, net on the Consolidated Statements of Operations. Variable lease income consists of rent primarily based on a percentage of revenues at the related properties and is included within Income from real property and Brokerage commissions and other, net on the Consolidated Statements of Operations. When collectability is not reasonably assured, the resident is placed on non-accrual status and revenue is recognized when cash payments are received.

Leases to Real Estate Operators

We do not have any operating leases with real estate operators at our MH or UK properties. At our RV communities and marinas, our non-cancellable leases with real estate operators where we are the lessor are classified as operating leases with lease income recognized on a straight line basis over the terms of the relevant lease agreement and is included within Income from real property and Brokerage commissions and other, net.

In addition, in December 2024, we sold one parcel of land in the U.S. for total consideration of $13.0 million and recorded a gain on sale of $10.9 million. In September 2024, we sold two development properties in the U.S. for total consideration of $37.2 million and recorded a gain on sale of $0.6 million. The two development properties were previously classified as held for sale. During the three months ended June 30, 2024, we recognized asset impairment charges of $10.8 million within the MH segment to reduce the carrying value of the two properties to an aggregate fair value of $36.1 million, driven by our change in strategic plan for these properties. The fair value measurement was determined using an income approach and Level 3 inputs based on a probability weighted holding period and estimated sale price for the assets. The asset impairment charges were recorded within Asset impairments on our Consolidated Statements of Operations.

Real Estate Held For Sale

We periodically classify real estate as "held for sale" after an active program to sell an asset has commenced and when the sale is probable. Subsequent to the classification of assets as held for sale, no further depreciation expense is recorded.

In December 2024, we reached an agreement to sell a portfolio of RV properties for total cash consideration of $92.9 million. The total consideration included proceeds from the disposition of four RV properties that we owned and termination of the associated ground leases, along with proceeds from the settlement of a developer note receivable for which three additional developer-owned properties were included in the portfolio of RV properties sold. As a result, the carrying value of total non-financial assets of $47.5 million was reclassified from Investment property, net to Other assets, net as of December 31, 2024. During the year ended December 31, 2024, we recognized asset impairment charges of $12.1 million to reduce the carrying value of the four owned RV properties to an aggregate fair value of $47.5 million. The fair value measurement was determined using a market approach and Level 2 inputs based on the estimated sale price for the assets. The asset impairment charges were recorded within Asset impairments on our Consolidated Statements of Operations. Refer to Note 4, "Notes and Other Receivables" and for additional details related to the developer note receivable. Refer to Note 20, "Subsequent Events" for additional information related to this disposition occurring after December 31, 2024.

2023 Disposition Activity

In August 2023, we sold one MH community located in Maine with 155 developed sites at its net carrying value for cash consideration of $6.8 million. The property was previously classified as held for sale during the three months ended June 30, 2023, with its net carrying value of $13.1 million written down by $6.3 million within Asset impairments on our Consolidated Statements of Operations, to a fair value less cost to sell of $6.8 million.

In February 2023, we sold two parcels of land in the United Kingdom for total consideration of $111.5 million. The consideration consisted of $108.8 million in the form of an operator note receivable that was added to an existing facility with a weighted average interest rate of 11.9% per annum, due May 31, 2023 and subsequently extended to July 31, 2023 as part of the operator's total facility. On the date of sale, the carrying value of the note receivable approximated its fair value due to its short term nature. The dispositions resulted in a loss on sale totaling $2.2 million during the year ended December 31, 2023, net of the release of foreign currency translation losses from Accumulated other comprehensive income ("AOCI") of $11.9 million. The total loss on sale was recorded in Gain / (loss) on dispositions of properties on the Consolidated Statements of Operations. As of December 31, 2023, we have reacquired these two parcels of land at fair value as part of the settlement of the related note receivable, with no remeasurement gain or loss recognized.

In February 2023, the criteria was met to classify Sandy Bay, an operating MH community in the UK, with 730 developed sites, as held for sale. Previously, this property had been under contract. At December 31, 2023, the sale contract was no longer in effect, and due to an unexpected change in circumstance related to the counterparty, we reclassified the property as held for use. In accordance with ASC Topic 360, "Property, Plant, and Equipment," we recorded the property at the lower of the carrying amount before the asset was held for sale, adjusted for depreciation and amortization expense that would have been recognized had the asset been continually classified as held for use, and the fair value at the time of the reclassification. During the three months ended December 31, 2023, we recorded depreciation and amortization expense of $1.3 million in conjunction with the reclassification of the property. The following assets and liabilities, which were previously classified as held for sale within Other assets and Other liabilities, respectively, were reclassified as of December 31, 2023: Investment in property, net of $259.0 million, Inventory of manufactured homes of $4.6 million, Other intangible assets of $1.3 million, and Other liabilities, net of $55.8 million.

Sun NG Resorts Transaction

During the three months ended December 31, 2023, we simplified the structure of certain of our consolidated variable interest entities, including Sun NG RV Resorts, Sun NG Whitewater RV Resorts LLC, Sun NG Beaver Brook LLC and four standalone affiliates (collectively "Sun NG") in a transaction with our joint venture partner in Sun NG. The transaction, which was primarily a non-monetary exchange and resulted in a net cash receipt of $8.2 million, consisted of the following:

•Disposition of our majority equity interest in three consolidated joint venture properties (including Sun NG Whitewater RV Resorts LLC) with a fair value of $166.1 million, which resulted in a gain of $13.2 million.
•Acquisition of all noncontrolling equity interests in 14 consolidated joint venture properties and a significant portion of the noncontrolling equity interest in five stand-alone joint venture properties (including Sun NG Beaver Brook LLC) with a fair value of $149.5 million. This resulted in us owning a 100% controlling interest in 14 of these properties (the "Acquired RV Properties") and a majority interest in the remaining properties. The acquisition of the noncontrolling interest was accounted for as an equity transaction in accordance with ASC Topic 810, "Consolidation," with the difference between the fair value and carrying value of the acquired noncontrolling interest of $125.3 million recorded as a decrease to Additional paid-in capital.
•Settlement of the Series A and Series B preferred equity interests in the Sun NG Resorts joint venture of $35.2 million and $3.9 million, respectively, and issuance of 20,000 Series L preferred OP units valued at $2.0 million. The Series A and Series B preferred equity interests were accounted for as Unsecured debt and Temporary Equity on our Consolidated Balance Sheets, respectively. The Series L preferred OP units were recorded in Noncontrolling Interests in the Consolidated Balance Sheets.
•Disposition of our ownership interest in Rezplot, a nonconsolidated affiliate, and settlement of notes receivable due from Rezplot for $12.2 million. In conjunction with the disposition, we remeasured the investment to its fair value and recorded a gain of $15.3 million.

Refer to Note 7, "Investments in Nonconsolidated Affiliates" related to the sale of our investment in Rezplot, Note 8, "Debt and Line of Credit" related to the settlement of the Series A preferred equity interest, and Note 9, "Equity and Temporary Equity" related to the acquisition of the noncontrolling equity interest in 14 consolidated joint venture properties and issuance of Series L preferred OP units.

Other receivables, net241.6 267.5 
Total Notes and Other Receivables, net$484.0 $421.6 
Installment Notes Receivable on Manufactured Homes

Installment notes receivable are measured at fair value, using indicative pricing models from third party valuation specialists, in accordance with ASC 820, "Fair Value Measurements and Disclosures." The balances of installment notes receivable of $93.9 million (principal of installment notes receivable of $95.2 million less fair value adjustment of $1.3 million) and $19.6 million (principal of installment notes receivable of $20.4 million less fair value adjustment of $0.8 million) as of December 31, 2024 and 2023, respectively, are secured by manufactured homes. The notes represent financing to purchasers of manufactured homes located in our communities and require monthly principal and interest payments. The notes had a net weighted average interest rate (net of servicing costs) and maturity of 6.4% and 18.6 years as of December 31, 2024, and 6.9% and 17.2 years as of December 31, 2023, respectively. Refer to Note 15, "Fair Value Measurements," for additional details.
Notes Receivable from Real Estate Developers and Operators

Notes receivable from real estate developers and operators are measured at fair value, using indicative pricing models from third party valuation specialists, in accordance with ASC 820, "Fair Value Measurements and Disclosures." Refer to Note 15, "Fair Value Measurements," for additional information.

Notes Receivable from Real Estate Operators

The notes receivable from real estate operators consists of a loan provided to a real estate operator to fund the Canadian RV Portfolio disposition (the "Canadian RV Note"), and a fully drawn loan provided to Royale Holdings Group HoldCo Limited, a real estate development owner and operator in the UK, and certain other parties, to fund investing and financing activities (the "UK Note"). The UK Note was fully settled as of December 31, 2024.

The balance on the Canadian RV Note was $42.4 million with a net weighted average interest rate and maturity of 5.0% and two years as of December 31, 2024. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional details related to the Canadian RV Portfolio disposition.

The UK Note was collateralized by a first-priority security interest in three real estate assets and three MH manufacturers in the UK. During the year ended December 31, 2023, we appointed receivers over the real estate assets and acquired these assets through a credit bid. As part of this process, we engaged third party valuation specialists to appraise the real estate assets in accordance with ASC 820. The appraisals were completed using the discounted cash flow method (income approach), with the significant assumptions being development density, estimated absorption rate, home sale price, and discount rate. As of December 31, 2023, the real estate assets appraised at a fair value totaling $263.8 million, and the UK Note balance was reduced by this amount, with an offsetting adjustment to Investment property, net on our Consolidated Balance Sheets.

As of December 31, 2023, the balance remaining on the UK Note, which was in nonaccrual status, collateralized by a first-priority security interest in three MH manufacturers in the UK, was adjusted to fair value totaling $10.8 million (gross notes receivable of $114.3 million, inclusive of accrued interest of $10.4 million, less a fair value adjustment of $103.5 million).

During the three months ended March 31, 2024, we completed a receivership process related to the three MH manufacturers in the UK. The receivers sold such assets for a total consideration of $10.7 million, resulting in cash proceeds of $7.0 million, net of non-cash consideration and fees. The sale of these assets resulted in an incremental fair value remeasurement adjustment of $0.8 million that was recorded in Loss on remeasurement of notes receivable on the Consolidated Statements of Operations.

Other acquisition and construction loans provided to real estate developers total $183.6 million with a net weighted average interest rate and maturity of 8.0% and 1.9 years as of December 31, 2024, and total $123.7 million with a net weighted average interest rate and maturity of 9.2% and 2.6 years as of December 31, 2023. As of December 31, 2024 and 2023, the additional acquisition and construction loans provided to real estate developers had $36.8 million and $39.5 million of undrawn funds, respectively. During the year ended December 31, 2024, we recorded a fair value adjustment loss of $35.2 million, primarily related to the sale of a portfolio of RV communities that closed in January 2025. The fair value adjustment loss reflects the relative fair value of the underlying collateral to the developer note receivable settled in conjunction with the transaction. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional detail related to the disposition and Note 20, "Subsequent Events," for activity subsequent to December 31, 2024.

(2)During the three months ended September 30, 2024, we recorded a charge of $8.9 million to write off a receivable balance related to expected insurance proceeds from a prior litigation matter. We concluded that the loss recovery was no longer probable of being realized and recorded the charge within General and administrative expense on the Consolidated Statements of Operations.

5. Collateralized Receivables and Transfers of Financial Assets

During the three months ended December 31, 2023, we completed a transfer of our installment notes receivable to an unrelated entity and received net cash proceeds of $53.4 million from the third-party servicer, in exchange for relinquishing our right, title and interest in the receivables. During the year ended December 31, 2024, we received a subsequent cash payment of $1.1 million from the servicer in accordance with the terms of the transfer. We have no further obligations or rights with respect to the control, management, administration, servicing or collection of the installment notes receivables. However, we are subject to certain recourse provisions requiring us to purchase the underlying manufactured homes collateralizing such notes at a price calculated based on the agreed upon terms, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement which precluded establishing legal isolation, and therefore these transferred loans do not meet the requirements for sale accounting under ASC 860, "Transfers and Servicing."

The transaction has been accounted for in accordance with ASC 860-30, with the transferred assets classified as Collateralized receivables, net and the cash proceeds received from this transaction classified as Secured borrowings on collateralized receivables within the Consolidated Balance Sheets. We have elected to apply the fair value option to the collateralized receivables and related secured borrowings under ASC 820, "Fair Value Measurements and Disclosures." The balance of collateralized receivables was $51.2 million (gross collateralized receivable of $52.0 million less fair value adjustments of $0.8 million) and $56.2 million (gross collateralized receivable of $59.1 million less fair value adjustments of $2.9 million) as of December 31, 2024 and December 31, 2023, respectively. The balance of secured borrowings on collateralized receivables was $51.2 million (gross secured borrowings of $47.3 million plus fair value adjustments of $3.9 million) and $55.8 million (gross secured borrowings of $53.9 million plus fair value adjustments of $1.9 million) as of December 31, 2024 and December 31, 2023, respectively. The notes represent financing to purchasers of manufactured homes located in our communities and require monthly principal and interest payments. The notes had a net weighted average interest rate and maturity of 8.6% and 13.2 years as of December 31, 2024 and 8.6% and 14.2 years as of December 31, 2023. Refer to Note 15, "Fair Value Measurements," for additional details.

The collateralized receivables earn interest income and the secured borrowings accrue interest expense at the same amount. The amount of interest income and interest expense recognized during the years ended December 31, 2024 and December 31, 2023 was $4.7 million and $0.6 million, respectively.

6. Goodwill and Other Intangible Assets

Our intangible assets include goodwill, in-place leases, non-competition agreements, trademarks and trade names, customer relationships, franchise agreements, and other intangible assets.

Goodwill

The measurement periods for the valuation of assets acquired and liabilities assumed in a business combination end as soon as information on the facts and circumstances that existed as of the acquisition dates becomes available on the earlier of (i) the dates of acquisition, or (ii) 12 months after the acquisition dates. Adjustments in purchase price allocations may require a change in the amounts allocated to goodwill during the periods in which the adjustments are determined. These purchase accounting adjustments are presented under Other in the table below. Changes in the carrying amount of goodwill during the years ended December 31, 2024 and 2023, respectively, by reportable segment were as follows (in millions):

(2) During the years ended December 31, 2024 and 2023, we recorded aggregate non-cash goodwill impairment charges of $180.8 million and $369.9 million within Goodwill impairment on the Consolidated Statements of Operations, respectively. The declines in the fair value of the Park Holidays reporting unit within the UK reporting segment were primarily driven by a deterioration in the macroeconomic environment in the region, leading to a higher weighted average cost of capital, inflationary pressures, and changing competitive market dynamics, causing a decline in projected future cash flows for our Park Holidays business.
(3) During the year ended December 31, 2023, adjustments in purchase price allocations resulted in the recognition of additional goodwill of $60.7 million in the UK segment, related to the Park Leisure business combination.
(4) During the three months ended September 30, 2024, we recorded goodwill of $0.2 million in the Marina segment related to the acquisition of Oak Leaf, primarily attributed to the enterprise value associated with existing operations. The total recognized goodwill of $0.2 million is expected to be deductible for income tax purposes.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Prior to March 2024, the aggregate amount of our senior credit facility was $4.2 billion with the ability to upsize the total borrowings by an additional $800.0 million, subject to certain conditions. The aggregate amount under the senior credit facility consisted of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, pound sterling, euros, Canadian dollars and Australian dollars, subject to certain limitations. The maturity date of the revolving loan facility is April 7, 2026. At our option that maturity date may be extended two additional six-month periods.

In March 2024, we terminated the term loan facility and settled the associated $1.1 billion of borrowings outstanding under the term loan by increasing our borrowings under the revolving loan of the senior credit facility. By terminating the term loan, we reduced our aggregate borrowing capacity under the senior credit facility to $3.05 billion under the revolving loan. During the three months ended March 31, 2024, we recognized a Loss on extinguishment of debt in our Consolidated Statements of Operations of $0.6 million related to the termination of the term loan facility. In June 2024, we amended the senior credit facility to replace the Canadian Dollar Offered Rate with the CORRA as the benchmark rate for borrowings denominated in Canadian dollars, with no other significant changes to the terms of the senior credit facility.

The senior credit facility bears interest at a floating rate based on the Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Australian BBSY, the Daily SONIA Rate or the CORRA, as applicable, plus a margin, in all cases, which can range from 0.725% to 1.6%, subject to certain adjustments. As of December 31, 2024, the margins based on our credit ratings were 0.85% on the revolving loan facility.

At the lenders' option, the senior credit facility will become immediately due and payable upon an event of default under the Credit Facility Agreement. We had $1.4 billion and $944.1 million of borrowings outstanding under the revolving loan as of December 31, 2024 and 2023, respectively. The balance is recorded in Unsecured debt on the Consolidated Balance Sheets.

The senior credit facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the senior credit facility, but does reduce the borrowing amount available. We had $11.5 million and $26.2 million of outstanding letters of credit at December 31, 2024 and 2023, respectively.

Unsecured Term Loan

In October 2019, we assumed a $58.0 million secured term loan facility related to an acquisition. The term loan initially had a four-year term ending October 29, 2023, and bore interest at a floating rate based on the Eurodollar rate or Prime rate plus a margin ranging from 1.2% to 2.05%. Effective July 1, 2021, we amended the agreement to release the associated collateral, extend the term loan facility maturity date to October 29, 2025 and adjust the interest rate margin to a range from 0.8% to 1.6%. In August 2022, we amended the unsecured term loan facility to transition from the Eurodollar rate to SOFR. During the three months ended June 30, 2024, we settled the term loan facility and had no balance outstanding as of December 31, 2024. The outstanding balance was $7.8 million at December 31, 2023 and was recorded in Unsecured debt on the Consolidated Balance Sheets.

Preferred Equity - Sun NG Resorts - Mandatorily Redeemable

In connection with the investment in Sun NG Resorts in June 2018, unrelated third parties purchased $35.3 million of mandatorily redeemable Series A Preferred Equity ("Preferred Equity - Sun NG Resorts") that carried a preferred rate of return of 6.0% per annum and had a seven-year term ending June 1, 2025. In December 2023, we settled the remaining outstanding Preferred Equity - Sun NG Resorts balance of $35.2 million as part of the transaction with our joint venture partners in Sun NG. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional information related to the broader transaction with our joint venture partner in Sun NG.

Temporary Equity

Temporary equity includes preferred securities that are redeemable for cash at the holder's option or upon the occurrence of an event that is not solely within our control based on a fixed or determinable price and other redeemable equity interests. These securities are not mandatorily redeemable for cash nor do they contain a fixed maturity date. The following table sets forth the various series of redeemable preferred OP units and other redeemable equity interests that were outstanding as of December 31, 2024 and 2023, and the related terms, and summarizes the balance included within Temporary Equity on our Consolidated Balance Sheets (in millions, except for statistical information):

10. Share-Based Compensation

As of December 31, 2024, we had two share-based compensation plans: the Sun Communities, Inc. 2015 Equity Incentive Plan (as amended, the "2015 Equity Incentive Plan") and the First Amended and Restated 2004 Non-Employee Director Option Plan (as amended, the "2004 Non-Employee Director Option Plan"). We believe granting equity awards will provide certain executives, key employees and directors with additional incentives to promote our financial success and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future. Time based awards for directors generally vest over three years. Time based awards for key employees and executives generally vest over five years. Market condition awards for executives generally vest after three years. As of December 31, 2024, the number of shares of common stock that may be issued under the 2015 Equity Incentive Plan is 4,750,000. As of December 31, 2024, there were 2,638,822 shares available for future issuance.

Restricted Stock

The majority of our share-based compensation is awarded as service vesting restricted stock grants to executives and key employees. We have also awarded restricted stock to our non-employee directors. We measure the fair value associated with these awards using the closing price of our common stock as of the grant date to calculate compensation cost. Employee awards typically vest over several years and are subject to continued employment by the employee. Award recipients receive non-forfeitable distribution payments on unvested shares of restricted stock.

2004 Non-Employee Director Option Plan

The types of awards that may be granted under the 2004 Non-Employee Director Option Plan are options, restricted stock, and OP units. Only non-employee directors are eligible to participate in this plan. The maximum number of options, restricted stock, and OP units that may be issued under this plan is 375,000 shares. As of December 31, 2024, 121,965 shares remained available for future issuance.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
On November 6, 2024, pursuant to John McLaren's appointment as President, we issued 50,000 shares of restricted common stock, 20,000 of which will vest in equal annual installments over five years ("time based shares"), and 30,000 of which are subject to performance vesting after three years based on certain market performance criteria ("market based shares"). In accordance with ASC 718, we concluded that the grant date for the time based shares was November 6, 2024 and we recognized these shares under the applicable guidance. In contrast, for the market based shares, we concluded that the grant date had not yet occurred as of December 31, 2024 due to the pending terms of the award. Accordingly, we will begin to accrue compensation cost and recognize the market based shares in our share count during the year ending December 31, 2025, once applicable under ASC 718.

11. Segment Reporting

ASC Topic 280, "Segment Reporting," establishes standards for the way that business enterprises report information about operating segments in its financial statements. As described in Note 1, "Significant Accounting Policies," effective January 1, 2024, we expanded our organizational structure from three segments, which consisted of (i) manufactured home ("MH") communities, (ii) recreational vehicle ("RV") communities, and (iii) Marinas to add a fourth segment that includes communities in the United Kingdom ("UK"). The new structure reflects how the chief operating decision maker manages the business, makes operating decisions, allocates resources, and evaluates operating performance. Beginning with the three months ended March 31, 2024, we are reporting our financial results consistent with our newly realigned operating segments and have recast prior period amounts to conform to the way we internally manage our business and monitor segment performance. Certain reclassifications have been made to the prior period financial statements and related notes in order to conform to the current period presentation. There was no impact to prior period net income, shareholders' equity or cash flows for any of the reclassifications.

We group our segments into reportable segments based upon similarities in products and services and geography. Our four reportable segments are: (i) MH communities, (ii) RV communities, (iii) Marinas, and (iv) communities in the UK. Each operating segment has discrete financial information evaluated regularly by our chief operating decision maker in managing the business, making operating decisions, allocating resources, and evaluating operating performance.


F - 38
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
The chief operating decision maker ("CODM") is a committee comprised of our Chief Executive Officer, Chief Operating Officer, and Chief Financial Officer. The CODM uses NOI to allocate resources (including employees, property, and financial or capital resources) for each segment predominately in the annual budgeting and forecasting process. The CODM considers budget-to-actual variances on a monthly basis for both profit measures when making decisions about allocating capital and personnel to the segments. The CODM also uses NOI for evaluating product pricing and segment profit and in the compensation of certain employees. The CODM reviews balance sheet information at a consolidated level.

The MH segment owns, operates, develops, or has an interest in, a portfolio of MH communities in the U.S., and is in the business of acquiring, operating and developing ground-up MH communities to provide affordable housing solutions to residents. The MH segment in the U.S. also provides manufactured home sales and leasing services to tenants and prospective tenants of our communities.

The RV segment owns, operates, develops, or has an interest in, a portfolio of RV communities and is in the business of acquiring, operating and developing group-up RV communities in the U.S. and Canada. It also provides leasing services for vacation rentals within the RV communities.

The Marina segment owns, operates and develops marinas, and is in the business of acquiring and operating marinas in the U.S., with the majority of such marinas concentrated in coastal regions, and others located in various inland regions.

The UK segment owns, operates, develops, or has an interest in, a portfolio of communities, referred to as holiday parks, and is in the business of acquiring, operating and developing communities in the United Kingdom. It also provides home sales and associated site license activities to owners and tenants within the communities.

12. Income Taxes

We have elected to be taxed as a REIT pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended ("Code"). In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT taxable income (calculated without any deduction for dividends paid and excluding capital gains) to its shareholders and meet other tests.

Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the year ended December 31, 2024.

As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on the ordinary taxable income we distribute to our shareholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates. Even if we qualify as a REIT, we may be subject to certain state and local income taxes, as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes. We are also subject to local income taxes in Canada, Puerto Rico, and the UK due to certain properties located in those jurisdictions. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside of the U.S. As currently structured, we are not subject to UK withholding taxes on distributions from our UK properties.

For income tax purposes, distributions paid to common shareholders consist of ordinary income, capital gains, and return of capital. For the years ended December 31, 2024, 2023, and 2022, distributions paid per share were taxable as follows (unaudited / rounded):

Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards, depreciation, interest and basis differences between tax and GAAP. Our deferred tax assets that have a full valuation allowance relate to our taxable REIT subsidiaries.

Our U.S. taxable REIT subsidiaries operating loss carryforwards are $154.5 million, or $32.0 million after tax, including SHS loss carryforwards of $149.4 million, or $31.4 million after tax, as of December 31, 2024. The loss carryforwards will begin to expire in 2025 through 2036 if not offset by future taxable income. In addition, our Canadian subsidiaries have operating loss carryforwards of $0.2 million, or $0.1 million after tax, as of December 31, 2024. The loss carryforwards will begin to expire in 2040 through 2042 if not offset by future taxable income.

Our policy is to report income tax penalties and income tax related interest expense as a component of income tax expense. No interest or penalty associated with any unrecognized income tax provision or benefit was accrued, nor was any income tax related interest or penalty recognized during the years ended December 31, 2024, 2023, and 2022.

13. Earnings / (Loss) Per Share

Earnings / (loss) per share ("EPS") is computed by dividing net earnings / (loss) by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted EPS using the more dilutive of the treasury stock method and the two-class method for stock option and restricted common shares, the treasury stock method for forward equity sales, and the if converted method for convertible units.

From time to time, we enter into forward equity sales agreements, which are discussed in Note 9, "Equity and Temporary Equity." We considered the potential dilution resulting from the forward equity sales agreements on the EPS calculations. At inception, the agreements do not have an effect on the computation of basic EPS as no shares are delivered unless there is a physical settlement. Common shares issued upon the physical settlement of the forward equity sales agreements, weighted for the period these common shares are outstanding, are included in the denominator of basic EPS. To determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement, we calculate the number of weighted-average shares outstanding - diluted in accordance with the treasury stock method.

Our potentially dilutive securities include our potential common shares related to our forward equity offerings, our unvested restricted common shares, and our Operating Partnership outstanding common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units, Series D preferred OP units, Series E preferred OP units, Series F preferred OP units, Series G preferred OP units, Series H preferred OP units, Series J preferred OP units, Series K preferred OP units, and Series L preferred OP units, which, if converted or exercised, may impact dilution.


F - 44
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Diluted EPS considers the impact of potentially dilutive securities except when the potential common shares have an anti-dilutive effect. Our unvested restricted stock common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing EPS. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average number of shares outstanding during the period. The two-class method determines EPS by (1) dividing the sum of distributed earnings and undistributed earnings allocated to common shareholders by the weighted average number of shares of common stock outstanding for the period; and (2) dividing the sum of distributed earnings and undistributed earnings allocated to participating securities by the weighted average number of shares of participating securities for the period. The remaining potential dilutive common shares do not contain rights to distributions and are included in the computation of diluted EPS.

Computations of basic and diluted EPS were as follows (in millions, except per share data):

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value:

Cash, Cash Equivalents and Restricted Cash

The carrying values of cash, cash equivalents and restricted cash approximate their fair market values due to the short-term nature of the instruments. These are classified as Level 1 in the hierarchy.

Marketable Securities

During the year ended December 31, 2023, we sold our 41.8 million share marketable security position in Ingenia, generating $102.5 million of proceeds, net of $1.0 million of underwriting and other fees, with a realized loss of $8.0 million. The proceeds were used to pay down amounts drawn under our senior credit facility.
Installment Notes Receivable on Manufactured Homes and Collateralized Receivables

Installment notes receivable on manufactured homes and collateralized receivables are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs, inclusive of default rates, interest rates and recovery rates (Level 3). Refer to Note 4, "Notes and Other Receivables" and Note 5, "Collateralized Receivables and Transfers of Financial Assets," for additional information.

Notes Receivable from Real Estate Developers and Operators

Notes receivable from real estate developers and operators are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs including interest rates and counterparty performance (Level 3). The carrying values of the notes generally approximate their fair market values either due to the nature of the note and / or the note being secured primarily by underlying real estate and other collateral and / or personal guarantees. Refer to Note 4, "Notes and Other Receivables," for additional information.


F - 49
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Derivatives Assets and Liabilities - Interest Rate Derivatives

Interest rate derivatives are recorded at fair value and consist of interest rate swaps and forward swaps. The fair value of these financial instruments are measured using observable inputs based on the SOFR and SONIA Rates, respectively (Level 2).

Secured Debt

Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Secured borrowings on collateralized receivables - recorded at fair value and adjusted based on the same interest rates as the related collateralized receivables (Level 3). Refer to Note 5, "Collateralized Receivables and Transfers of Financial Assets" and Note 8, "Debt and Line of Credit," for additional information.

Unsecured Debt

Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Line of credit and other unsecured debt - consists primarily of our senior credit facility. We have variable rates on our senior credit facility. The fair value of the debt with variable rates approximates carrying value as the interest rates of these amounts approximate market rates (Level 2). The estimated fair value of our debt as of December 31, 2024 approximated its gross carrying value.

Other Financial Liabilities

We estimate the fair value of contingent consideration liabilities based on valuation models using significant unobservable inputs that generally consider discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 3).

Level 3 Reconciliation, Measurements, and Transfers

We review the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. Availability of secondary market activity and consistency of pricing from third-party sources impacts our ability to classify securities as Level 2 or Level 3. There were no transfers into or out of Level 3 during the years ended December 31, 2024 and 2023.

Fair Value Measurements on a Nonrecurring Basis

We review the carrying value of long-lived assets to be held for use for impairment quarterly or whenever events or changes in circumstances indicate a possible impairment. During the year ended December 31, 2024, we recognized asset impairment charges of $24.1 million due to a strategy shift pertaining to certain development properties and other assets within our MH and RV segments. The fair value measurement was determined by estimating discounted cash flows using certain unobservable Level 3 inputs, based on the expectation that the development projects are no longer probable of being realized. During the year ended December 31, 2024, we also recorded impairment charges of $22.9 million related to properties that were reclassified to held for sale and subsequently sold. The impairment charges were recorded within Asset impairments on the Consolidated Statements of Operations. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional information.


F - 51
SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
During the year ended December 31, 2024, we recorded a goodwill impairment charge of $180.8 million to write down the carrying value of the Park Holidays reporting unit within the UK reporting segment to its fair value. The fair value measurement process utilized both an income approach and a market approach and primarily unobservable Level 3 inputs. After the impairment charge, the fair value of goodwill within the UK reporting segment was $0 as of December 31, 2024. Refer to Note 1, "Significant Accounting Policies," and Note 6, "Goodwill and Other Intangible Assets," for additional information.

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop fair value estimates. The fair value estimates are based on information available as of December 31, 2024. As such, our estimates of fair value could differ significantly from the actual carrying value.

16. Commitments and Contingencies

Legal Proceedings - Class Action Litigation

Since August 31, 2023, several putative class action complaints have been filed in the U.S. District Court for the Northern District of Illinois, Eastern Division, against Datacomp Appraisal Systems, Inc., us, and nine other large MH operators in the U.S. The complaint alleges that the defendants have violated federal antitrust laws by sharing and receiving competitively sensitive non-public information to maintain artificially high site rents. The complaints have been consolidated into the case captioned In re Manufactured Home Lot Rents Antitrust Litigation, No. 1:23-cv-06715.

Plaintiffs seek both injunctive relief and monetary damages, as well as attorneys' fees. We are unable to estimate a range of loss, if any, that could result were there to be an adverse final decision in this litigation. If an unfavorable result were to occur, it is possible that the impact could be material to our results of operations in the periods in which any such outcome becomes probable and estimable.

We believe that the plaintiffs' allegations are without merit and intend to defend against them vigorously. However, litigation is inherently uncertain and there can be no assurance regarding the likelihood that our defense of this litigation will be successful.

Other Legal Proceedings

We are involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

Catastrophic Event-Related Charges

Hurricanes Helene and Milton - In September and October 2024, Hurricane Helene and Hurricane Milton, respectively, made landfall in Florida and subsequently impacted several of our properties in the Southeastern and Mid-Atlantic regions of the U.S. During the year ended December 31, 2024, we recognized charges of $13.9 million for debris removal and clean-up at various MH and RV properties, as well charges of $4.4 million for impaired assets at several of our marinas, which were recorded within Catastrophic-event related charges, net on the Consolidated Statements of Operations. We maintain property, casualty, flood, and business interruption insurance for our properties, subject to customary deductibles and limits.

Hurricane Ian - When Hurricane Ian made landfall on Florida's western coast in September 2022, the storm primarily affected three RV properties in the Fort Myers area, comprising approximately 2,500 sites. These properties sustained significant flooding and wind damage from the hurricane. At other affected MH and RV properties, most of the damage was limited to trees, roofs, fences, skirting and carports. At affected marina properties, docks, buildings, and landscaping sustained wind and water damage. We maintain property, casualty, flood, and business interruption insurance for our community portfolio, subject to customary deductibles and limits.

Estimated property insurance recoveries, excluding business interruption recoveries, of $49.2 million related to Hurricane Ian were recorded in Notes and other receivables, net on the Consolidated Balance Sheets as of December 31, 2024.

Total estimated insurance receivable - December 31, 2024$49.2 

We are actively working with our insurance providers on claims for business interruption recoveries. During the year ended December 31, 2024, we recognized $16.7 million, net of deductibles, for the lost earnings from Hurricane Ian covering the period from September 1, 2023 through May 31, 2024. The business interruption proceeds were recorded within Brokerage commissions and other, net in our Consolidated Statements of Operations. The related communities are under redevelopment and we have gradually started to lease developed sites at these communities to customers. However, we currently cannot estimate a date when operating results will be restored to pre-hurricane levels. Our business interruption insurance policy provides for up to 60 months of coverage from the date of restoration.

During the year ended December 31, 2024, we received an insurance recovery of $1.6 million in excess of previously estimated costs related to damages incurred at certain marinas due to Hurricane Ian. The insurance recovery gain was recorded within Catastrophic event-related charges, net on the Consolidated Statements of Operations.

In December 2023, one of our RV properties with approximately 300 sites sustained property damage due to heavy rainfall and flooding in the North Conway, New Hampshire area. Based on a preliminary review performed by an insurance adjuster, we recognized asset impairment charges of $7.0 million during the year ended December 31, 2023, primarily related to site improvements, vacation rental cabins, and equipment. During the year ended December 31, 2024, we recognized incremental charges of $12.0 million related to the impacted property, comprised of $3.1 million for impaired assets and $8.9 million for debris removal, cleanup, and repairs. We received $6.4 million in insurance proceeds during the nine months ended September 30, 2024 related to the flood event. The charges and related proceeds were recorded within Catastrophic event-related charges, net in our Consolidated Statements of Operations. The foregoing estimates are based on current information available after the preliminary review of the damages incurred. Actual charges and insurance recoveries could differ from these estimates. Any changes to these estimates will be recognized in the period(s) in which they are determined.

The foregoing estimates for each respective event are based on current information available, and we continue to assess these estimates. Actual charges and insurance recoveries could vary significantly from these estimates. Any changes to these estimates will be recognized in the period(s) in which they are determined.

17. Leases

Lessee Accounting

We lease land under non-cancelable operating leases at certain properties expiring at various dates through 2100. The majority of the leases have terms requiring fixed payments plus additional rents based on a percentage of revenues at those properties. We also have other operating leases, primarily office space and equipment expiring at various dates through 2042.

Each of Brian M. Hermelin, Ronald A. Klein, and Arthur A. Weiss indirectly owns less than one percent interest in American Center LLC. Mr. Shiffman is our Chairman of the Board and Chief Executive Officer. Mr. Hermelin is a director of the Company, and Mr. Klein and Mr. Weiss were directors of the Company until their respective retirements in May and December 2024. Under this agreement, we lease approximately 60,261 rentable square feet of permanent space. The lease agreement includes annual graduated rent increases through the initial end date of October 31, 2026. As of December 31, 2024, the average gross base rent was $21.45 per square foot. Each of Mr. Shiffman, Mr. Hermelin, Mr. Klein and Mr. Weiss may have a conflict of interest with respect to his obligations as our officer and / or director and his ownership interest in American Center LLC.

Use of Airplane - Gary A. Shiffman is the beneficial owner of an airplane that we use from time to time for business purposes. During the years ended December 31, 2024, 2023, and 2022, we paid $0.2 million, $0.5 million, and $0.7 million for the use of the airplane, respectively. Mr. Shiffman may have a conflict of interest with respect to his obligations as our officer and director and his ownership interest in the airplane.

Legal Counsel - Arthur A. Weiss is a partner at Taft Stettinius & Hollister LLP, which acts as our general counsel and represents us in various matters. Mr. Weiss was also a member of the Board until his retirement on December 31, 2024.

Tax Consequences Upon Sale of Properties - Gary A. Shiffman holds limited partnership interests in the Operating Partnership which were received in connection with the contribution of properties from partnerships previously affiliated with him. Prior to any redemption of these limited partnership interests for our common stock, Mr. Shiffman will have tax consequences different from those on us and our public shareholders upon the sale of any of these partnerships. Therefore, we and Mr. Shiffman may have different objectives regarding the appropriate pricing and timing of any sale of those properties.

19. Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

On January 1, 2024, we adopted ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." In accordance with the new standard, we have provided enhanced disclosure of significant segment expenses that are regularly provided to the CODM to assess segment performance, an amount and description of the composition for other segment items to reconcile to segment profit or loss, and the title and position of our chief operating decision maker. The adoption of this ASU did not have a material impact on our Consolidated Financial Statements. Refer to Note 11, "Segment Reporting," for additional information.

Recent Accounting Pronouncements - Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative," which adds interim and annual disclosure requirements to the US GAAP codification at the request of the SEC. The new guidance is intended to align GAAP requirements with those of the SEC and to facilitate the application of GAAP for all entities. These disclosure requirements are currently included in either SEC Regulation S-X or SEC Regulation S-K. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited and the amendments should be applied prospectively. If the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K by June 30, 2027, the amendments will be removed from the US GAAP codification and will not be effective.

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires disclosure of specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, this amendment requires certain disclosure of income taxes paid disaggregated by federal, state and foreign taxes, and the amount of income taxes paid disaggregated by individual jurisdiction in which income taxes paid meet a quantitative threshold. The new guidance is intended to enhance the transparency and decision usefulness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted and the amendments should be applied prospectively. We are currently evaluating the provisions of this amendment and the impact on our Consolidated Financial Statements and related disclosures.

In January 2025, we sold a portfolio of four RV properties located in Virginia, Delaware, and Florida, terminated the associated ground leases, and settled a developer note receivable for three developer-owned properties for total cash consideration of $92.9 million. The four RV properties were previously classified as held for sale. Refer to Note 3, "Real Estate Acquisitions and Dispositions," for additional details related to the disposition.

Equity Transaction

In January 2025, we entered into a non-monetary transaction with a real estate developer to settle a note receivable of $23.7 million in exchange for settlement of contingent consideration of $8.4 million in conjunction with one RV property in California and redemption of 200,914 Series G preferred OP units held by the real estate developer. After the redemption, there were 4,898 Series G preferred OP units outstanding.

Safe Harbor Sale

In February 2025, we announced that we had entered into an agreement to sell Safe Harbor for an all-cash purchase price of $5.65 billion, subject to certain post-closing adjustments. While the Safe Harbor Sale is anticipated to close in the second quarter of 2025, the Safe Harbor Sale is subject to certain closing conditions and rights of termination, and it may not be completed on the anticipated timeline or at all. The Safe Harbor Sale is expected to generate approximately $5.5 billion of pre-tax proceeds after transaction costs, which we expect to use to support a combination of debt reduction, distributions to shareholders, and reinvestment in our core businesses.

The Safe Harbor Sale represents the disposition of our Marina reporting segment and a strategic shift in operations. Accordingly, the historical results of the Marina reporting segment and assets and liabilities included in the disposition will be presented in our consolidated financial statements as held for sale and as discontinued operations beginning in the first quarter of 2025. The initial closing of the Safe Harbor Sale is expected to take place during the second quarter of 2025. Upon closing, we expect to realize an estimated gain on sale of approximately $1.3 billion within Income from discontinued operations, net on our Consolidated Statement of Operations. Any such gain on sale may result in the realization of deferred tax assets for which a valuation allowance was recorded as of December 31, 2024. Certain marina properties representing approximately 10% of the total consideration may be transferred and paid for in one or more subsequent closings, subject to receipt of certain third-party approvals.

We have evaluated our Consolidated Financial Statements for subsequent events through the date that this Form 10-K was issued.
