ITEM 2.     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 the accompanying Notes, along with our 2025 Annual Report.

OVERVIEW

We are a fully integrated REIT. As of June 30, 2026, we owned and operated, directly or indirectly, or held an interest in, a portfolio of 455 developed properties located in the U.S. and Canada including 295 MH communities and 160 RV communities. At that date, we also owned, operated, or held an interest in a portfolio of 54 UK properties, which were classified within discontinued operations as of June 30, 2026.

We have been in the business of operating, acquiring, developing and expanding MH and RV communities since 1975. 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. In the U.S., we are also engaged in the marketing, selling and leasing of 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.

Over the past several years, we have shifted our strategy toward optimizing the value of our core business through achieving strong rental rate growth and operating efficiencies, while also pursuing select new acquisition opportunities that meet our capital investment criteria. In 2025, the Safe Harbor Sale advanced our strategy of focusing on our core business and enhanced our leverage profile and financial flexibility. We believe we are positioned for organic growth in 2026 with expected rental rate increases, occupancy gains, and expense management as we focus on increasing long-term value for shareholders.

PARK HOLIDAYS SALE

During the three months ended June 30, 2026, we announced the Park Holidays Sale. The Park Holidays Sale represents the expected disposition of our UK business and a strategic shift in operations. Accordingly, the results of the UK business and assets and liabilities included in the disposition are presented as held for sale and as discontinued operations for all periods presented herein. Unless otherwise noted, all amounts, percentages, and discussions below reflect only the results of operations and financial condition of our continuing operations. The Park Holidays Sale is subject to receipt of regulatory approval from the UK Financial Conduct Authority, and is expected to close in the second half of 2026.

The Park Holidays Sale accelerates our strategy of focusing on our core North American MH and RV portfolio and enhances our liquidity and credit profile. After the closing of the Park Holidays Sale, the majority of our total NOI will be generated by Real Property NOI from properties located within the U.S.

SIGNIFICANT ACCOUNTING POLICIES

We have identified significant accounting policies that, as a result of the judgments, uncertainties, and complexities of the underlying accounting standards and operations involved could result in material changes to our financial condition or results of operations under different conditions or using different assumptions. Details regarding significant accounting policies are described fully in our Annual Report on Form 10-K for the year ended December 31, 2025.

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 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.

SUN COMMUNITIES, INC.

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 property 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 net cash provided by 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.

Same Property NOI - This is a key 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, 2025. Same properties exclude ground-up development properties, acquired properties, properties classified as discontinued operations, properties impacted by catastrophic weather events, and properties sold after December 31, 2024. 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 ancillary 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, real estate related depreciation and amortization, gains (or losses) from change in control, impairments of certain real estate assets and investments, and adjustments for nonconsolidated 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 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 to FFO, 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") to evaluate our performance. These adjustments include acquisition and other transaction costs, gains and losses from the early extinguishment of debt, costs related to catastrophic weather events, net of insurance recoveries, gains and losses on foreign currency exchanges, and other miscellaneous non-comparable items, such as restructuring costs.

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. Certain financial information has been revised to reflect reclassifications in prior periods to conform to current period presentation.

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 net operating income ("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, 2025, we owned and operated, directly or indirectly, or had an interest in, a portfolio of 513 developed properties located in the U.S., Canada, and the UK including 294 MH communities, 166 RV communities, and 53 UK communities.

23

SUN COMMUNITIES, INC.

We have been in the business of operating, acquiring, developing and expanding MH and RV communities since 1975, and communities in the United Kingdom 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 are also engaged in the marketing, selling and leasing of 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. In the United Kingdom, our UK 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.

In 2025, we continued our portfolio optimization and simplification strategy by completing the Safe Harbor Sale for total net cash proceeds of $5.5 billion, generating a total gain on sale of $1.5 billion. The Safe Harbor Sale accelerates our strategy of focusing on our core business and significantly enhances our leverage profile and financial flexibility. We have deployed the majority of the cash proceeds from the Safe Harbor Sale to implement a capital allocation plan that reflects a balanced, tax-efficient approach to optimize shareholder value through significantly lower leverage, greater financial flexibility to drive sustainable cash flow growth, and a thoughtful capital return strategy. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," in our accompanying Consolidated Financial Statements for additional details related to the Safe Harbor Sale.

Pursuant to our portfolio optimization strategy, we completed targeted, growth-oriented investment and acquisition opportunities in 2025, while also continuing our targeted disposition program to divest non-strategic assets in an effort to simplify management and maintain financial flexibility. During the year ended December 31, 2025, we acquired 11 MH and three RV properties for total cash consideration of $457.0 million and repurchased the titles to all 32 UK properties that were previously controlled via ground leases for total cash consideration of $386.8 million. Also during the year, we sold four MH properties, three RV properties, and three development land parcels in the U.S. and UK for a gross sale price of $202.6 million. The property dispositions have strengthened our financial position by enabling us to reduce debt while also exiting non-core markets. 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 Transition

Charles D. Young began serving as our CEO and as a Director on October 1, 2025. Mr. Young succeeds Gary Shiffman, who retired as our CEO after a distinguished 40 years leading Sun Communities. We entered into an employment agreement with Mr. Young under which he will serve as our CEO for a five year term, which is automatically renewable thereafter for successive one-year terms unless either party timely terminates the agreement. Refer to the Form 8-K filed with the SEC on July 23, 2025 for additional details related to Mr. Young's employment agreement.

Mr. Shiffman will continue to serve as the Chairman of our Board of Directors. Refer to the Form 8-K filed with the SEC on December 16, 2025 for additional details related to Mr. Shiffman's transition services agreement.

EXECUTIVE SUMMARY

2025 General Overview

Key operational and financial highlights included the following:

•Completed the disposition of the Safe Harbor Marinas business for an aggregate purchase price of $5.65 billion.

•Acquired 11 MH and three RV properties for total cash consideration of $457.0 million, which was primarily sourced from 1031 exchange escrow accounts to minimize the tax impact from the Safe Harbor Sale.

•Repurchased 4.3 million shares of our common stock at an average cost of $125.62 per share for a total of $539.1 million.

•Completed the redemption of $956.5 million in outstanding unsecured senior notes, inclusive of prepayment costs of $56.5 million.

•Completed the repayment of $1.6 billion under our senior credit facility and $737.7 million of secured mortgage debt, inclusive of prepayments costs of $45.9 million.

•Entered into a new $2.0 billion multi-currency revolving credit facility that matures on January 31, 2030.

•Completed the repurchase of titles to 32 UK properties that were previously controlled via ground leases, reducing our financial liability by $355.9 million.

•Total revenues from continuing operations for 2025 were $2.3 billion, consistent with 2024 total revenues.

•Net income from continuing operations was $0.6 million in 2025, as compared to $32.9 million in 2024.

•Net income attributable to SUI common shareholders was $1.4 billion, as compared to a net income attributable to SUI common shareholders of $89.0 million in the prior year, driven primarily by a total gain of $1.5 billion from the Safe Harbor Sale in 2025.

•Achieved annual Core FFO of $6.68 per diluted share and OP unit.

•Achieved real property Same Property NOI growth of 8.9% for MH and 3.5% for the UK over 2024. For the RV segment, we experienced a decline in Same Property NOI growth of 1.4%, driven by lower than anticipated real property - transient revenues.

•Increased Same Property adjusted blended occupancy for MH and RV by 40 basis points to 99.1% as compared to 98.7% in 2024.

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.

(1) Occupancy percentage includes annual RV sites and excludes transient RV sites.

(2) Occupancy percentage excludes recently completed but vacant expansion sites.

25

SUN COMMUNITIES, INC.

Markets

Our MH and RV properties are largely concentrated in the U.S. in Florida, Michigan, Texas, and California, which collectively contain 64.7% 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.

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 93.2% of our total holiday parks.

The following table identifies our largest MH and RV markets by total sites:

The following table identifies our holiday park markets in the UK by total sites:

(1) Occupancy percentage excludes transient RV sites. Percentage calculated by dividing revenue producing sites by developed sites. A revenue producing site is defined as a site that is occupied by a paying resident or reserved by a customer with annual or seasonal usage rights. A developed site is defined as an adequately sized parcel of land that has road and utility access which is zoned and licensed (if required) for use as a home site.

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 NOI and FFO as supplemental performance measures. We believe NOI and FFO are appropriate measures given their wide use by and relevance to investors and analysts. Investors and analysts following the real estate industry use these supplemental non-GAAP measures to assess REITs. 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 net income for the effects of GAAP depreciation / amortization of real estate assets and gains or losses on real estate dispositions. 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 property 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 net cash provided by 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.

Same Property NOI - This is a key 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, 2024. Same properties exclude ground-up development properties, acquired properties, properties classified as discontinued operations, and properties sold after December 31, 2023. 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 ancillary 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. For the UK segment, we present Same Property NOI growth rate information on a constant currency basis to provide a framework for assessing how our underlying properties performed after excluding the effects of changes in exchange rates. We believe that the presentation of UK Same Property NOI on a constant currency basis helps to improve the ability to understand our performance because it excludes the effects of foreign currency volatility which are not indicative of our core operating results in the region.

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 nonconsolidated 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 to FFO, 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") to evaluate our performance. These adjustments include acquisition and other transaction costs, gains and losses from the early extinguishment of debt, costs related to catastrophic weather events, net of insurance recoveries, gains and losses on foreign currency exchanges, and other miscellaneous non-comparable items.

28

SUN COMMUNITIES, INC.

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. Certain financial information has been revised to reflect reclassifications in prior periods to conform to current period presentation.

RESULTS OF OPERATIONS

Summary Statements of Operations

The following tables reconcile the Net income / (loss) attributable to SUI common shareholders to NOI and summarize our consolidated financial results (in millions):

(1) Excludes properties classified as discontinued operations. During the years ended December 31, 2025, 2024, and 2023 our marina properties generated total NOI of $93.7 million, $322.7 million, and $312.0 million, respectively, which was recorded within Income from discontinued operations, net on the Consolidated Statements of Operations. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," for additional information.

Seasonality of Revenue

The RV 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:

Real Property Operations - Total Portfolio

The following tables reflect certain financial and other information for our real estate operations by segment (in millions, except for statistical information):

N/A = Not applicable.

(1) MH annual sites included 12,518 and 10,923 rental homes in our Rental Program at December 31, 2025 and 2024, respectively. Our investment in occupied rental homes at December 31, 2025 was $921.3 million, an increase of 17.7% from $783.0 million at December 31, 2024.

For the year ended December 31, 2025, the $43.5 million, or 4.3%, increase in Real Property NOI as compared to the same period in 2024, consists of an increase of $56.0 million from Same Property MH, and an increase of $2.7 million from Same Property UK, partially offset by an NOI decrease of $11.1 million, net from properties outside of the Same Property population due to portfolio disposition activity that took place in 2024, primarily driven by the disposition of 10 MH properties for total gross sales proceeds of $349.1 million.

Real Property Operations - North America Same Property Portfolio

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 UK segment, the amounts in the tables below reflect constant currency for comparative purposes.

(1) Same Property results for our UK properties reflect constant currency for comparative purposes. British pound sterling figures in the prior comparative period have been translated at the average exchange rate of $1.3183 USD per GBP, during year ended December 31, 2025. Prior to constant currency adjustments, UK Same Property NOI increased by 7.3% during the year ended December 31, 2025.

(2) Percentages are calculated based on unrounded numbers.

(3) We net certain utility revenues (which include utility reimbursement revenues from residents) against related utility expenses in property operating expenses as follows (in millions):

SUN COMMUNITIES, INC.

(1) Adjusting for recently delivered and vacant expansion sites, Same Property adjusted occupancy decreased by 30 basis points year over year, to 89.7% at December 31, 2025, from 90.0% at December 31, 2024.

(2) Calculated using actual results without rounding.

For the years ended December 31, 2025 and 2024:

•The MH segment's increase in NOI of $56.0 million, or 8.9% when compared to the same period in 2024, is primarily due to an increase in real property (excluding transient) revenue of $62.4 million, or 7.2% and NOI outperformance in our Rental Program. Real property (excluding transient) revenue increased primarily due to a 5.2% increase in monthly base rent.

•The RV segment's decrease in NOI of $4.1 million, or 1.4% when compared to the same period in 2024, is primarily due an increase in Same Property operating expenses of $4.3 million or 1.8% and a decrease in real property transient revenue of $21.1 million or 9.0%, partially offset by an increase in real property (excluding transient) revenue of $21.3 million or 7.5% due to conversions of transient RV sites to annual RV sites. The increase in Same Property operating expenses was primarily due to increases in utilities, real estate taxes, and other expenses.

•The UK segment increase in NOI of $2.7 million, or 3.5% when compared to the same period in 2024 is primarily due to a $4.2 million, or 4.1%, increase in real property (excluding transient) revenue and a $3.4 million, or 7.1%, increase in real property transient revenue; partially offset by an increase in Same Property operating expenses of $4.9 million, or 6.6%. The increase in real property (excluding transient) revenue was primarily due to a 4.1% increase in monthly base rent per site. The increase in Same Property operating expenses was primarily due to increases in payroll wages, utilities, and other expenses.

For the years ended December 31, 2024 and 2023:

•The Same Property data for the comparative period includes all properties that we owned and operated continuously since January 1, 2023, exclusive of ground-up development and redevelopment properties recently completed or under construction, and other properties as determined by management.
