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.

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;

•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.

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.

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;

•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;

•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.

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.

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.

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.

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.

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.

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.
