References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification (“ASC”). These unaudited Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and in accordance with GAAP. We present interim disclosures and certain information and footnote disclosures as required by SEC rules and regulations. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All significant intercompany transactions have been eliminated in consolidation.

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC on February 25, 2026 (our “2025 Annual Report”). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2025 Annual Report.

Real Estate Held for Sale and Discontinued Operations

In May 2026, we entered into a definitive agreement to sell all of the outstanding equity of our United Kingdom (“UK”) subsidiaries (referred to herein as “Park Holidays” or the “UK business”) to Panther Bidco Limited (the “Park Holidays Sale”). On September 22, 2026, we completed the closing of the Park Holidays Sale and fully divested our investment in the UK business, which represented a strategic shift in operations. Accordingly, the results of the UK business and assets and liabilities included in the disposition have been reflected as discontinued operations through the final transaction closing date. Certain reclassifications have been made to prior period financial statements and related notes in order to conform to current period presentation.

In February 2025, we entered into a definitive agreement to sell our former Safe Harbor Marinas, LLC subsidiary (“Safe Harbor”) for an aggregate purchase price of approximately $5.65 billion, subject to certain adjustments (the “Safe Harbor Sale”). The Safe Harbor Sale represented the sale of our former marina business and a strategic shift in operations. Accordingly, the results of the Safe Harbor business have been reflected as discontinued operations on our Condensed Consolidated Statements of Operations through the final transaction closing date of August 29, 2025.

Unless otherwise noted, the information disclosed in Note 3 through Note 17 refer only to our continuing operations and do not include discussion of balances or activity related to the UK and Safe Harbor businesses, which are each included within discontinued operations. Refer to Note 2, “Discontinued Operations,” for additional information.

Reportable Segments

As a result of the Park Holidays Sale, we revised our reporting structure from a three-segment to a two-segment structure, which consists of (i) manufactured home (“MH”) communities and (ii) recreational vehicle (“RV”) communities. Refer to Note 10, “Segment Reporting,” for additional information.

Park Holidays Sale

In May 2026, we entered into the Park Holidays Sale, which represents a strategic shift in operations that will have a major effect on our operations and financial results. Accordingly, the results of the UK business and assets and liabilities included in the Park Holidays Sale have been reclassified as discontinued operations through the final transaction closing date of September 22, 2026 pursuant to ASC 205-20, “Presentation of Financial Statements: Discontinued Operations.” As of June 30, 2026, we determined that the fair value of the UK business, including costs to sell, was lower than its carrying value. Prior to the second quarter of 2026, the UK business was managed and evaluated on a held-and-used basis. Although management routinely evaluates strategic alternatives and capital allocation opportunities across its portfolio, including opportunities related to its UK operations, no definitive decision had been made to sell the business and we continued to invest in the growth and expansion of the business up until the announcement of the Park Holidays Sale. Accordingly, during the three months ended June 30, 2026, we recorded a non-cash valuation allowance charge of $1.1 billion against the assets held for sale to reduce the carrying value of the UK business to its estimated fair value less costs to sell. The fair value was estimated using the expected sale price as negotiated with the buyer, a market participant assumption and Level 2 fair value input. Costs to sell included estimated incremental, direct costs incurred to transact the Park Holidays Sale. The charge was recorded within Income / (loss) from discontinued operations, net on our Condensed Consolidated Statements of Operations.

During the three months ended September 30, 2026, we completed the closing of the Park Holidays Sale for gross sales proceeds of £772.3 million (or approximately $1.05 billion), after certain customary locked box and other adjustments. The closing of the Park Holidays Sale generated cash proceeds to the Company of approximately $1.03 billion, net of closing and employee separation costs. In conjunction with the closing, we recorded an increase to the valuation allowance and loss on disposal of $50.6 million, primarily driven by settlement of working capital related to the sale. The increase to the valuation allowance and loss on disposal was recorded within Income / (loss) from discontinued operations, net on our Condensed Consolidated Statements of Operations.

In connection with the Park Holidays Sale, we recorded a deferred tax asset within our continuing operations related to loss carryforwards with a corresponding valuation allowance. As of September 30, 2026, the deferred tax asset was $78.9 million, and the net deferred tax asset was $0, after recording a full valuation allowance.

We have limited continuing involvement with Park Holidays primarily with respect to providing a continuation of certain IT services through no later than May 31, 2027 under a transition services agreement. Revenue earned from this arrangement during the three months ended September 30, 2026 was not material.

(4) Includes redeemable equity interests related to joint ventures that primarily operate and maintain solar energy equipment in select communities in the U.S. In August 2026, we acquired the noncontrolling equity interest in a joint venture for a total purchase price of $0.1 million, which resulted in us owning 100% ownership in the joint venture. The acquisition was accounted for as an equity transaction with the difference between the purchase price and the acquired noncontrolling interest of $2.8 million recorded as an increase to Additional Paid-in Capital on the Condensed Consolidated Balance Sheets.

Universal Shelf Registration Statement

We have filed a universal shelf registration statement on Form S-3 with the SEC, which provides for the registration of unspecified amounts of equity and debt securities. The authorized number of shares of our capital stock is 380,000,000 shares, of which 360,000,000 shares are common stock and 20,000,000 shares are preferred stock. As of September 30, 2026, we had 119,941,693 shares of common stock issued and outstanding and no shares of preferred stock were issued and outstanding.

At the Market Offering Sales Agreement

We have entered into an At the Market Offering Sales Agreement (the “ATM”) with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock. Through September 30, 2026, we had entered into and settled forward sales agreements under the ATM for an aggregate gross sales price of $524.8 million, leaving $725.2 million available for sale under the ATM.

Stock Repurchase Program

In May 2026, our Board of Directors authorized a stock repurchase program (the “Stock Repurchase Program”) under which we may repurchase up to $1.0 billion in shares of our outstanding common stock through May 27, 2027. The Stock Repurchase Program renews our previous stock repurchase program and provides us with continued flexibility to repurchase shares of our common stock. Under the Stock Repurchase Program, we may repurchase shares of our common stock from time to time in open market transactions, through privately negotiated transactions, through one or more accelerated repurchases, or otherwise, in accordance with the terms set forth in Rule 10b5-1 and Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and other applicable legal requirements. The Stock Repurchase Program does not obligate us to repurchase any specific number of shares, and we may initiate, suspend, or discontinue purchases under the Stock Repurchase Program at any time.

We account for stock repurchases in accordance with ASC 505, “Equity,” by allocating the repurchase price to Common stock, Additional paid-in capital, and Distributions in excess of accumulated earnings on the Condensed Consolidated Balance Sheets. Under Maryland corporate law, our state of incorporation, there is no concept of treasury shares. As a result, all repurchased shares are retired and returned to the status of authorized but unissued shares upon settlement. During the three months ended September 30, 2026, we repurchased and retired 2.4 million shares of our outstanding common stock for $293.3 million. During the nine months ended September 30, 2026, we repurchased and retired 3.8 million shares of our outstanding common stock for $464.5 million. As of September 30, 2026, we had $595.5 million remaining authorized for purchase under this program.

Accumulated Other Comprehensive Income

Redemption of Preferred OP Units

Subject to certain limitations, holders can redeem certain series of preferred OP units for cash, provided that the applicable contractual requirements are met. The preferred OP units were redeemed for a total net cash payment, inclusive of all distributions on the redeemed units that were accrued and unpaid as of the redemption date, in accordance with the terms and conditions set forth in the redemption agreement.

9. Share-Based Compensation

As of September 30, 2026, we had two share-based compensation plans: the Sun Communities, Inc. 2015 Equity Incentive Plan (as amended, the “2015 Equity Incentive Plan”) and the First Amended and Restated 2004 Non-Employee Director Option Plan (as amended, the “2004 Non-Employee Director Option Plan”). Outstanding awards include time-based and performance-based restricted stock awards (“RSAs”) and performance-based restricted stock units (“RSUs”). We believe granting equity awards will provide certain executives, key employees, and directors additional incentives to promote our financial success and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future. Time-based awards for directors generally vest over three years. Time-based awards for key employees and executives generally vest over three years to five years. Market and performance condition awards for executives generally vest after three years. For RSAs, award recipients receive non-forfeitable distribution payments on unvested shares. For RSUs, award recipients receive forfeitable distribution equivalents on unvested units with payment upon vesting.

During the nine months ended September 30, 2026, we granted performance-based RSUs to certain executives that provide the right to receive shares of our common stock at a future date. The performance-based RSUs vest at up to 200% of the target number of units, with the ultimate number of shares to be issued based on the total shareholder return of the Company’s common stock and / or operating performance metrics, measured over a three-year performance period. In accordance with ASC 718, “Compensation-Stock Compensation,” the fair value of RSUs subject to a market condition was measured using a Monte Carlo valuation model and the fair value of RSUs subject to a performance condition was measured based on the expected probability that the underlying units will vest using actual results and the forecast for the respective key performance metric during the performance period.

During the nine months ended September 30, 2026, we granted the RSUs listed below. We did not grant any RSUs during the nine months ended September 30, 2025:

Modifications

During the nine months ended September 30, 2026, we modified certain unvested RSAs to accelerate the vesting terms such that the respective awards vested in connection with the termination or retirement of the eligible grantees (“accelerated vestings”). We accounted for the accelerated vestings as modifications under ASC 718, “Compensation-Stock Compensation,” and recognized compensation expense based on the incremental fair value of the modified awards. Accordingly, during the nine months ended September 30, 2026, we recognized accelerated share-based compensation expense of $13.8 million within General and administrative expense related to 88,546 time-based RSAs and 94,200 performance-based RSAs previously subject to a market condition.

The vesting requirements for 307,574 and 189,679 restricted shares granted to our executives, directors, and employees were satisfied during the nine months ended September 30, 2026 and 2025, respectively.

We recognized total share-based compensation costs from our continuing operations within General and administrative expense on the Condensed Consolidated Statements of Operations of $6.3 million and $6.9 million during the three months ended September 30, 2026 and 2025, and $32.0 million and $21.7 million during the nine months ended September 30, 2026 and 2025, respectively.

10. Segment Reporting

ASC 280, “Segment Reporting,” establishes standards for the way that business enterprises report information about operating segments in their financial statements. As described in Note 1, “Basis of Presentation,” effective during the three months ended June 30, 2026, we have revised our reporting structure from three reportable segments to two reportable segments, which consists of (i) MH communities, and (ii) RV communities. The segment reporting structure reflects how the chief operating decision maker (“CODM”), a committee comprised of our Chief Executive Officer, President and Chief Operating Officer, and Chief Financial Officer, manages the business, makes operating decisions, allocates resources, and evaluates operating performance.

Each segment is primarily evaluated based on Net Operating Income (“NOI”). The CODM uses NOI to allocate resources (including employees, property, and financial or capital resources) for each segment predominately in the annual budgeting and forecasting process. The CODM considers budget-to-actual variances on a monthly basis for this profit measure when making decisions about allocating capital and personnel to the segments. The CODM also uses NOI for evaluating product pricing and segment profit and in the compensation of certain employees. The CODM reviews balance sheet information at a consolidated level.

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

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

11. Earnings / (Loss) Per Share

Earnings / (loss) per share (“EPS”) is computed by dividing net income / (loss) by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted EPS using the more dilutive of the treasury stock method and the two-class method for restricted common shares, the treasury stock method for RSUs and forward equity sales, and the if converted method for convertible units. Our potentially dilutive securities include our unvested restricted common shares and RSUs, and our Operating Partnership outstanding common and preferred OP units, which, if converted or exercised, may impact dilution.

Diluted EPS considers the impact of potentially dilutive securities except when the potential common shares have an anti-dilutive effect. Our unvested restricted common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing EPS.

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

We have excluded certain potentially dilutive securities from the computation of diluted EPS because the inclusion of those securities would have been anti-dilutive for the periods presented. For the nine months ended September 30, 2026, all outstanding convertible securities were dilutive and included in the computation of diluted EPS. The following table presents the outstanding securities that were excluded from the computations of diluted EPS for the three months ended September 30, 2026 and the three and nine months ended September 30, 2025 (in thousands):

12. Derivative Financial Instruments and Hedging Activities

We have historically utilized treasury rate lock contracts, interest rate swaps, and forward swaps for interest rate risk management purposes. We have also periodically entered into forward swaps and forward contracts to hedge foreign currency exchange risk exposures. We do not enter into derivative instruments for speculative purposes.

At September 30, 2026 and December 31, 2025, we did not have any outstanding derivative contracts. For previously settled cash flow hedges of interest rate risk, the unrealized gains or losses on the derivative instruments are recorded in AOCI and are reclassified to Interest expense on the Condensed Consolidated Statements of Operations during the same period in which the hedged transaction affects earnings. We estimate that $3.5 million will be reclassified as a reduction to Interest expense, net over the next 12 months.

Derivative Contract Activity

During the nine months ended September 30, 2026, we entered into foreign exchange forward contracts with a notional amount totaling $1.1 billion, which each expired upon reaching their respective maturity dates. These forward contracts were entered into as economic hedges of foreign currency exposure to the British pound in connection with the anticipated receipt of cash from the closing of the Park Holidays Sale.

The following table presents the gains recorded in earnings on derivative instruments that were utilized as economic hedges and not designated as hedging instruments (in millions):

13. Fair Value Measurements

Assets by Hierarchy Level

The table below sets forth our financial assets and liabilities (in millions) that required disclosure of fair value on a recurring basis as of September 30, 2026 and December 31, 2025. The carrying values of cash, cash equivalents and restricted cash, other receivables and accounts payable approximate their fair values since their maturities are less than one year. These financial instruments are classified as Level 1 in the hierarchy and are excluded from the table below.

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

Installment Notes Receivable on Manufactured Homes and Collateralized Receivables

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

Notes Receivable from Real Estate Operators

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

Secured Debt

Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on management estimates and on quoted rates, rates currently prevailing for comparable loans, and instruments of comparable maturities (Level 2). Refer to Note 7, “Debt and Line of Credit,” for additional information.

SUN COMMUNITIES, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(Unaudited)

Secured borrowings on collateralized receivables is recorded at fair value and adjusted based on the same interest rates as the related collateralized receivables (Level 3). Refer to Note 7, “Debt and Line of Credit,” for additional information.

Unsecured Debt

Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on quoted rates, rates currently prevailing for comparable loans, and instruments of comparable maturities (Level 2). Refer to Note 7, “Debt and Line of Credit,” for additional information.

Other Financial Liabilities

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

Level 3 Reconciliation, Measurements, and Transfers

We review the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. Availability of secondary market activity and consistency of pricing from third-party sources impacts our ability to classify securities as Level 2 or Level 3. There were no transfers into or out of Level 3 during the nine months ended September 30, 2026.

The following tables summarize changes to our financial instruments carried at fair value and classified within Level 3 of the fair value hierarchy for the three and nine months ended September 30, 2026 and 2025 (in millions):

Fair Value Measurements on a Nonrecurring Basis

As of September 30, 2026, assets measured at fair value on a non-recurring basis consisted of real estate assets that have been written down to an estimated fair value for impairment purposes. We review the carrying value of long-lived assets to be held for use for impairment quarterly or whenever events or changes in circumstances indicate a possible impairment. The fair value measurements were determined by using a market and / or income approach, as applicable, and unobservable Level 3 inputs. During the nine months ended September 30, 2026 and 2025, we recognized the following asset impairment charges (in millions, except for number of properties):

PeriodFair Value LevelNumber of PropertiesSegmentAsset Impairment ChargesAggregate Estimated Fair Value

(5)

7MH / RV$20.5 $93.4 

(1) The non-recurring fair value measurement was driven by a reduction in projected future cash flows for the impaired property and was determined using an income and market approach. The analysis was based upon market conditions, expectations for future growth and comparable transactions, and utilized unobservable quantitative inputs, including a capitalization rate of 8.5% and a discount rate of 10.5%.

(2) The non-recurring fair value measurement was driven by our contemplated change in strategic plan for the properties and was determined using a market approach. The fair value methodology included a probability weighted holding period and estimated sale price for the assets based on current market conditions and comparable transactions in the applicable geographic location.

(3) We also recorded other miscellaneous impairment charges of $3.8 million at several properties, primarily due to changes in strategy related to development projects and property damages.

(4) The non-recurring fair value measurement was driven by a reduction in projected future cash flows and deteriorating NOI trends for the impaired properties and was determined using an income and market approach. The analysis was based upon market conditions, expectations for future growth and comparable transactions, and utilized unobservable quantitative inputs, including capitalization rates ranging from 9.5% to 10.0% and discount rates ranging from 11.0% to 13.0%.

(5) The fair value measurement was driven by pre-construction development costs and determined by estimating discounted cash flows based on the expectation that the development projects are no longer probable of being realized.

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop fair value estimates. The fair value estimates are based on information available as of September 30, 2026. As such, our estimates of fair value could differ significantly from the actual carrying value.

14. Commitments and Contingencies

Legal Proceedings - Class Action Litigation

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

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

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

Other Legal Proceedings

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

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 September 30, 2026, we owned and operated, directly or indirectly, or held an interest in, a portfolio of 452 developed properties located in the U.S. and Canada including 295 MH communities and 157 RV communities.

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 (North American MH / RV) through achieving strong rental rate growth and operating efficiencies, while also pursuing select new acquisition opportunities that meet our capital investment criteria. The Safe Harbor Sale and Park Holidays Sale, which closed in 2025 and 2026, respectively, 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 September 30, 2026, we completed the closing of the Park Holidays Sale for gross sales proceeds of $1.05 billion, inclusive of certain adjustments, generating cash proceeds of $1.03 billion, net of closing and employee separation costs. The Park Holidays Sale represents the 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 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 accelerates our strategy of focusing on our core North American MH and RV portfolio. We intend to continue to utilize the cash proceeds from the Park Holidays Sale primarily to repurchase shares, pay down debt, and for general corporate purposes. Subsequent to the closing of the Park Holidays Sale, the majority of our total NOI is 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 that 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 other 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.

Seasonality of Revenue

The RV segment is 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. Properties may also have varying mixes of transient and annual sites. 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. During the nine months ended September 30, 2026, we recognized aggregate Real property - transient revenue from our RV segment of $28.4 million in the first quarter, $60.4 million in the second quarter, and $103.4 million in the third quarter.

During the year ended December 31, 2025, we recognized Real property - transient revenue as follows:

Real Property Operations - 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.

The following tables reflect certain financial and other information for our Same Property MH and RV portfolios as of and for the three and nine months ended September 30, 2026 and 2025 (in millions, except for statistical information):

Same Property NOI

For the three months ended September 30, 2026 and 2025:

•The MH segment increase in NOI of $11.8 million, or 6.9%, when compared to the same period in 2025 is primarily due to an increase in Real property revenue of $13.5 million, or 5.8% and NOI outperformance in our Rental Program. Real property revenue increased primarily due to a 5.2% increase in monthly base rent.

•The RV segment decrease in NOI of $1.4 million, or 1.3%, when compared to the same period in 2025 is primarily due to a decrease in Transient revenue of $1.0 million, or 1.1% and an increase in Same Property operating expenses of $2.5 million, or 3.2%, partially offset by an increase in Real property (excluding transient) revenue of $2.1 million, or 2.4%. The increase in Same Property operating expenses was primarily due to an increase in supplies and repairs expense.

For the nine months ended September 30, 2026 and 2025:

•The MH segment increase in NOI of $37.5 million, or 7.3%, when compared to the same period in 2025 is primarily due to an increase in Real property revenue of $43.1 million, or 6.2% and NOI outperformance in our Rental Program, partially offset by an increase in Same Property operating expenses of $5.6 million, or 3.1%. Real property revenue increased primarily due to a 5.2% increase in monthly base rent.

•The RV segment increase in NOI of $0.9 million, or 0.4%, when compared to the same period in 2025 is primarily due to an increase in Real property (excluding transient) revenue of $9.3 million, or 4.0%, partially offset by an increase in Same Property operating expenses of $3.9 million, or 2.1%. The increase in Real property (excluding transient) revenue was primarily due to a 3.9% increase in monthly base rent. The increase in Same Property operating expenses was primarily due to increases in supplies and repairs expense and utilities expense, net of reimbursements.

Ancillary, net - for the three months ended September 30, 2026, decreased primarily due to lower transient demand in the RV segment leading to a reduction in revenue generation from ancillary activities of $2.4 million in 2026, compared to the same period in 2025.

SUN COMMUNITIES, INC.

Interest income - for the three and nine months ended September 30, 2026, decreased due to a lower cash balance in 2026 after deploying cash to acquire new properties, pay down debt, and repurchase shares of our common stock.

We concluded that $36.5 million of the total settlement pertained to business interruption recoveries through 2027, which we recorded as a contingent gain in accordance with ASC 450, “Contingencies.” To better reflect the underlying economics of the transaction, we have elected to defer the business interruption recovery gain and recognize income ratably through 2027 for our presentation of Core FFO.

LIQUIDITY AND CAPITAL RESOURCES

Short-term Liquidity

Our principal short-term liquidity demands are expected to consist of distributions to our shareholders and the unit holders of the Operating Partnership through cash distributions and share repurchases, property acquisitions, development and expansion of our properties, capital improvement of our properties, and the purchase of new and pre-owned homes. We intend to meet our short-term liquidity requirements through available cash balances, cash flow generated from operations, cash generated from the Park Holidays Sale, draws on our Senior Credit Facility, and the use of debt and equity offerings under our shelf registration statement.

We employ a disciplined approach to selecting the optimal mix of financing sources to meet our liquidity demands and minimize our overall cost of capital. Our strategy centers on strengthening our core business, enhancing our leverage profile, and increasing financial flexibility. We continue to implement a balanced, tax-efficient capital allocation plan designed to optimize shareholder value by reducing leverage, enhancing financial flexibility to drive sustainable cash flow growth, and executing on a thoughtful capital return strategy. We intend to maintain our strong financial position and lower leverage profile by focusing on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and managing overhead costs.

Since our initial public offering in 1993, we have demonstrated operational reliability and cash flow strength throughout economic cycles. Our current objectives include streamlining our operations with an emphasis on our reliable real property income. We are positioned for ongoing organic growth with expected rental rate increases, occupancy gains, and expense management. In 2026, we continue to expect rental rate growth that exceeds headline inflation with ongoing focus on expense management to continue generating strong organic cash flow growth.

On September 22, 2026, we completed the closing of the Park Holidays Sale, generating cash proceeds of approximately $1.03 billion, net of closing and employee separation costs. The Park Holiday Sale resulted in the full divestment of our investment in the UK business, which will enable us to focus on our core North American MH and RV portfolio while further enhancing our financial flexibility. Refer to Note 1, “Basis of Presentation,” and Note 2, “Discontinued Operations,” for additional details related to the Park Holidays Sale.

On a year-to-date basis through September 30, 2026, we initiated the following capital allocation decisions:

•Repurchased 3.8 million shares of our common stock at an average cost of $121.09 per share for a total of $464.5 million.

•Repaid five mortgage term loans of $444.5 million, which were secured by 24 properties.

•Targeted reinvestment in strategic growth by acquiring one MH property for total cash consideration of $17.0 million, which was partially sourced from 1031 exchange escrow accounts to minimize tax impacts.

Subject to market conditions, and given the higher interest rate environment, we intend to selectively identify opportunities to acquire existing properties and expand our development pipeline. We finance acquisitions through available cash, secured financing, draws on our Senior Credit Facility, the assumption of existing debt on properties, and the issuance of debt and equity securities. Refer to Note 3, “Real Estate Acquisitions and Dispositions,” in our accompanying Condensed Consolidated Financial Statements for additional details on acquisitions and dispositions completed to date.

Cash Flow Activities

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

Nine Months Ended September 30,
20262025
Net Cash Provided By Operating Activities$650.7 $574.6 
Net Cash Used For Investing Activities$(137.5)$(68.9)
Net Cash Provided By / (Used For) Financing Activities$(419.6)$597.4 

Cash, cash equivalents and restricted cash for continuing operations increased by $92.6 million from $606.7 million as of December 31, 2025, to $699.3 million as of September 30, 2026.

Operating activities - Net cash provided by operating activities increased by $76.1 million to $650.7 million for the nine months ended September 30, 2026, compared to $574.6 million for the nine months ended September 30, 2025. The increase in operating cash flow was primarily due to growth in Same Property operating performance at our MH properties, a reduction in interest expense of $57.6 million in the current period due to the settlement of debt obligations in 2025, and favorable timing of changes in inventory, other assets, and other liabilities during the nine months ended September 30, 2026 as compared to the corresponding period in 2025.

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

•the market and economic conditions in our current markets generally, and specifically in the metropolitan areas of our current markets;

•lower occupancy and rental rates of our properties;

•increases in other operating costs, such as wage and benefit costs, supplies and repairs, real estate taxes, and utilities;

•substantial increases in insurance premiums;

•decreased sales of manufactured homes;

•current volatility in economic conditions and the financial markets; and

•the effects of outbreaks of disease and related restrictions on business operations.

See “Risk Factors” in Part I, Item 1A of our 2025 Annual Report, and Part II, Item 1A of our Quarterly Report on Form 10-Q for the three months ended June 30, 2026.

Investing activities - Net cash used for investing activities increased by $68.6 million to $137.5 million for the nine months ended September 30, 2026, compared to $68.9 million for the nine months ended September 30, 2025. The increase in Net cash used for investing activities was primarily driven by an increase in cash deployed to acquire new properties and decreases in cash proceeds received from disposition activity and notes receivable during the nine months ended September 30, 2026 as compared to the corresponding period in 2025.

Financing activities - Net cash used for financing activities was $419.6 million for the nine months ended September 30, 2026, compared to net cash provided by financing activities of $597.4 million for the nine months ended September 30, 2025. The change in Net cash provided by / (used for) financing activities was primarily driven by a net capital transfer of $1.0 billion from Park Holidays to the Company in conjunction with the Park Holidays Sale during the nine months ended September 30, 2026, compared to a net capital transfer of $5.5 billion from Safe Harbor to the Company in conjunction with the Safe Harbor Sale during the nine months ended September 30, 2025, partially offset by a reduction in cash deployed to settle debt obligations in the current period, as compared to the corresponding period in 2025. Refer to Note 2, “Discontinued Operations,” in our accompanying Condensed Consolidated Financial Statements for additional information.

Our cash flow from discontinued operations is summarized as follows (in millions):

Nine Months Ended September 30,
20262025
Net cash provided by operating activities - discontinued operations$39.7 $123.1 
Net cash provided by investing activities - discontinued operations$941.6 $5,452.9 
Net cash used for financing activities - discontinued operations$(1,010.4)$(5,564.5)

Cash, cash equivalents and restricted cash for discontinued operations decreased by $29.4 million from $29.4 million as of December 31, 2025, to zero as of September 30, 2026.

SUN COMMUNITIES, INC.

Operating activities - Net cash provided by operating activities for discontinued operations decreased by $83.4 million to $39.7 million for the nine months ended September 30, 2026, compared to $123.1 million for the nine months ended September 30, 2025. The decrease in Net cash provided by operating activities from discontinued operations was due to the inclusion of operating cash flow from Park Holidays and Safe Harbor during the nine months ended September 30, 2025, compared to a partial year of operating cash flow from Park Holidays during the nine months ended September 30, 2026.

Investing activities - Net cash provided by investing activities for discontinued operations decreased by $4.5 billion to $941.6 million for the nine months ended September 30, 2026, compared to $5.5 billion for the nine months ended September 30, 2025. The decrease in Net cash provided by investing activities for discontinued operations is driven by the proceeds received from the Park Holidays Sale in 2026, compared to the Safe Harbor Sale during the corresponding period in 2025. Refer to Note 2, “Discontinued Operations,” in our accompanying Condensed Consolidated Financial Statements for additional information on acquisitions and investment activity.

Financing activities - Net cash used for financing activities for discontinued operations decreased by $4.6 billion to $1.0 billion for the nine months ended September 30, 2026, compared to $5.6 billion for the nine months ended September 30, 2025. The decrease in Net cash used for financing activities for discontinued operations is driven by a reduced net capital transfer from the Park Holidays Sale in 2026, compared to the Safe Harbor Sale during the corresponding period in 2025. Refer to Note 2, “Discontinued Operations,” in our accompanying Condensed Consolidated Financial Statements for additional information.

We are exposed to interest rate variability associated with potential floating rate debt and any maturing debt that has to be refinanced. Interest rate movements impact our borrowing costs and, while as of September 30, 2026, 100% of our total debt was fixed rate financing, increases in interest costs have the potential to adversely affect our financial results.

Equity and Debt Activity

At the Market Offering Sales Agreement

We have entered into the ATM program with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock. Through September 30, 2026, we had entered into and settled forward sales agreements under the ATM for an aggregate gross sales price of $524.8 million, leaving $725.2 million available for sale under the ATM.

Stock Repurchase Program

In May 2026, our Board of Directors authorized a Stock Repurchase Program under which we may repurchase up to $1.0 billion in shares of our outstanding common stock through May 27, 2027. The Stock Repurchase Program renews our previous stock repurchase program and provides us with continued flexibility to repurchase shares of our common stock. Through September 30, 2026, we repurchased and retired 3.8 million shares of our outstanding common stock for $464.5 million. As of September 30, 2026, we had $595.5 million remaining authorized for purchase under this program. Refer to Note 8, “Equity and Temporary Equity,” in our accompanying Condensed Consolidated Financial Statements for additional information.

Senior Unsecured Notes

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

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

SUN COMMUNITIES, INC.

Credit Agreement

In September 2025, we entered into the Credit Agreement. Pursuant to the Credit Agreement, we may borrow up to $2.0 billion under a Senior Credit Facility. The Credit Agreement also permits, subject to the satisfaction of certain conditions, additional borrowings of $1.0 billion. The Senior Credit Facility’s maturity date is January 31, 2030, and, at our option, may be extended for two additional six-month periods subject to the satisfaction of certain conditions. During the three months ended September 30, 2026, we settled borrowings outstanding of $509.0 million under the Senior Credit Facility using proceeds from the Park Holidays Sale. As of September 30, 2026, there were no borrowings under the Senior Credit Facility. Refer to Note 7, “Debt and Line of Credit,” for additional information.

Financial Covenants

Pursuant to the terms of the Senior Credit Facility and senior unsecured notes payable, we are subject to various financial and other covenants. The most restrictive financial covenants for the Senior Credit Facility and senior unsecured notes payable are as follows:

Financial Covenants

Requirements

As of September 30, 2026

Credit Facility Covenants

Maximum leverage ratio<65.0%14.9%
Minimum fixed charge coverage ratio>1.405.22
Maximum secured leverage ratio<40.0%8.7%

Senior Unsecured Note Covenants

Total debt to total assets≤60.0%28.2%
Secured debt to total assets≤40.0%14.7%
Consolidated income available for debt service to debt service≥1.508.17
Unencumbered total asset value to total unsecured debt≥150.0%599.2%

As of September 30, 2026, we were in compliance with the above covenants and do not anticipate that we will be unable to meet these covenants in the near term.

Long-term Financing and Capital Requirements

Long-term Financing

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

As of September 30, 2026, we had unrestricted cash on hand of $658.9 million, $2.0 billion of remaining capacity on the Senior Credit Facility, and a total of 367 unencumbered MH and RV properties.

From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, issue unsecured notes, obtain other debt financing, or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the MH and RV industries at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional, and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those markets could make borrowing more difficult to secure, more expensive, or effectively unavailable. In the event our current credit ratings are downgraded, it may become difficult or more expensive to obtain additional financing or refinance existing unsecured debt as maturities become due. See “Risk Factors” in Part I, Item 1A of our 2025 Annual Report. If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations, and financial condition would be adversely impacted.

As of September 30, 2026, our debt has a weighted average interest rate of 3.32% and a weighted average maturity of 7.1 years.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Interest Rate Risk

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs, and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability that interest rate changes could have on our future cash flows. From time to time, we employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes. As of September 30, 2026, all of our outstanding debt obligations bore interest at fixed rates, which minimizes the impact of interest rate variability on our results of operations and cash flows in the near term. Additionally, we have exposure to long-term interest rates, which could affect the cost of refinancing existing debt or incurring additional debt in the future.

Capital Market Risk

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

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2026.

Changes in Internal Control over Financial Reporting

There were no changes in internal control over financial reporting during the three months ended September 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
