1. Basis of Presentation

Sun Communities, Inc., and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the "Operating Partnership"), Sun Home Services, Inc. ("SHS"), and our Park Holidays subsidiaries and the other entities through which we operate our business in the United Kingdom ("UK") are referred to herein as the "Company," "SUI," "us," "we," or "our."

We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB establishes accounting principles generally accepted in the United States of America ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification ("ASC"). These unaudited 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 Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited 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 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, 2024 as filed with the SEC on February 28, 2025 (our "2024 Annual Report"). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2024 Annual Report.

Real Estate Held for Sale and Discontinued Operations

In February 2025, we entered into a definitive agreement to sell Safe Harbor Marinas LLC ("Safe Harbor") for an aggregate purchase price of approximately $ 5.65 billion, subject to certain adjustments (the "Safe Harbor Sale"). In April 2025, we completed the initial closing of the Safe Harbor Sale. The subsequent closing of the transfer of subsidiaries owning 15 of Safe Harbor's properties (the "Delayed Consent Subsidiaries") with an aggregate agreed value of approximately $ 250.0 million was further subject to the receipt of certain third-party consents. On August 29, 2025, we completed the final closing of the Delayed Consent Subsidiaries and fully divested our investment in the Safe Harbor business. As a result, the results of the Marina business and assets and liabilities included in the disposition are presented as held for sale and 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. Unless otherwise noted, the information disclosed in Note 3 through Note 20 refers only to our continuing operations and do not include discussion of balances or activity related to Safe Harbor, which is included within discontinued operations. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," for additional information related to Safe Harbor and the Safe Harbor Sale.

Reportable Segments

As a result of the Safe Harbor Sale, we revised our reporting structure from a four -segment to a three -segment structure, which consists of (i) manufactured home ("MH") communities, (ii) recreational vehicle ("RV") communities, and (iii) communities in the United Kingdom ("UK"). Refer to Note 13, "Segment Reporting," for additional information.

Furthermore, service, retail, dining and entertainment revenues and expenses have been renamed as ancillary revenues and expenses to more appropriately reflect the nature of this activity for our continuing operations, after reclassifying the Marina results to discontinued operations. There was no impact to prior period net income, stockholders' equity, or cash flows due to the change in naming convention.

2. Assets Held for Sale and Discontinued Operations

In February 2025, we entered into an agreement to sell Safe Harbor, which represents a strategic shift in operations that is expected to have a major effect on our operations and financial results. Accordingly, the results of the Marina business and assets and liabilities included in the Safe Harbor Sale have been presented as discontinued operations through the final transaction closing date of August 29, 2025 under ASC 205-20, " Presentation of Financial Statements: Discontinued Operations ."

During the three months ended June 30, 2025, we completed the initial closing of the Safe Harbor Sale, which generated pre-tax cash proceeds of approximately $ 5.25 billion, net of transaction costs. Subsequent to the initial closing through June 30, 2025, we completed the sale of six Delayed Consent Subsidiaries for $ 136.7 million. In connection with the closings of the Safe Harbor Sale and the six Delayed Consent Subsidiaries, we recorded a gain on sale of $ 1.4 billion within Income from discontinued operations, net during the three months ended June 30, 2025. During the three months ended September 30, 2025, we completed the sale of the remaining nine Delayed Consent Subsidiaries for $ 117.5 million and recorded a gain on sale of $ 15.4 million within Income from discontinued operations, net.

The proceeds and related gain from the closing of the Safe Harbor Sale may be adjusted in future periods based on provisions in the agreement that allow for adjustments for working capital amounts and other miscellaneous items subsequent to the final transaction closing date of August 29, 2025.

7. Collateralized Receivables and Transfers of Financial Assets

We previously completed various transactions with an unrelated entity involving our installment notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivables. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivables. However, we are subject to certain recourse provisions requiring us to purchase the underlying manufactured homes collateralizing such notes at a price calculated based on the agreed upon terms, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement which precludes establishing legal isolation, and therefore these transferred loans do not meet the requirements for sale accounting under ASC 860, " Transfers and Servicing ."

The transaction has been accounted for in accordance with ASC 860-30, with the transferred assets classified as Collateralized receivables, net and the cash proceeds received from this transaction classified as Secured borrowings on collateralized receivables within the Consolidated Balance Sheets. We have elected to apply the fair value option to the collateralized receivables and related secured borrowings under ASC 820, " Fair Value Measurements and Disclosures ."

The following table sets forth certain information regarding collateralized receivables and the related secured borrowings (in millions, except interest rates and maturities):


	Collateralized Receivables						Secured Borrowings on Collateralized Receivables
	September 30, 2025			December 31, 2024			September 30, 2025			December 31, 2024
Gross Balance	$	46.5		$	52.0		$	41.7		$	47.3

Carrying Balance	$	45.4		$	51.2		$	45.4		$	51.2
Net Weighted Average Interest Rates	8.5		%	8.6		%	8.5		%	8.6		%
Weighted Average Years to Maturity	12.6 years			13.2 years			12.6 years			13.2 years

The collateralized receivables earn interest income and the secured borrowings accrue interest expense in equal amounts. The amount of interest income and interest expense recognized during the three and nine months ended September 30, 2025 was $ 1.0 million and $ 3.0 million, respectively, and during the three and nine months ended September 30, 2024 was $ 1.1 million and $ 3.5 million, respectively. Refer to Note 17, "Fair Value Measurements," for additional details.

Stock Repurchase Program

In May 2025, 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 April 30, 2026. Under the Stock Repurchase Program, we may repurchase shares of our common stock 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 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. Through September 30, 2025, we repurchased and retired 4.0 million shares of our outstanding common stock for $ 500.3 million. As of September 30, 2025, we had $ 499.7 million remaining authorized for purchase under this program.

13. 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 March 31, 2025, we revised our reporting structure from four segments to three segments as a result of the Safe Harbor Sale, consisting of (i) MH communities, (ii) RV communities, and (iii) the UK. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," for additional details regarding discontinued operations. Beginning with the three months ended March 31, 2025, we report our financial results consistent with our realigned operating segments and have recast prior period amounts to conform to the way we internally manage our business and monitor segment performance.

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.

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

14. Income Taxes

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

Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT during the three and nine months ended September 30, 2025.

As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on the ordinary taxable income we distribute to our shareholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates. Even if we qualify as a REIT, we may be subject to certain state and local income taxes, as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state, and local income taxes. However, we have a valuation allowance on our taxable REIT subsidiaries' deferred tax assets. During the three months ended June 30, 2025, we released a valuation allowance of $ 17.7 million to partially offset the Safe Harbor Marina gain on sale. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," for additional details related to the Safe Harbor Sale. We are also subject to local income taxes in Canada and the United Kingdom due to certain properties located in those jurisdictions. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside of the U.S. As currently structured, we are not subject to United Kingdom withholding taxes on distributions from our United Kingdom properties. We also may be subject to Australian withholding taxes on dividends from our Australian subsidiaries.

15. Earnings / (Loss) Per Share

Earnings / (loss) per share ("EPS") is computed by dividing net earnings / (loss) by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted EPS using the more dilutive of the treasury stock method and the two-class method for stock option and restricted common shares, the treasury stock method for forward equity sales and the if converted method for convertible units. Our potentially dilutive securities include our potential common shares related to our forward equity offerings, our unvested restricted common shares, and our Operating Partnership outstanding common 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 stock common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing EPS. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average number of shares outstanding during the period. The two-class method determines EPS by (1) dividing the sum of distributed earnings and undistributed earnings allocated to common shareholders by the weighted average number of shares of common stock outstanding for the period; and (2) dividing the sum of distributed earnings and undistributed earnings allocated to participating securities by the weighted average number of shares of participating securities for the period. The remaining potential dilutive common shares do not contain rights to distributions and are included in the computation of diluted EPS.

16. Derivative Financial Instruments

We utilize treasury rate lock contracts, interest rate swaps, and forward swaps for interest rate risk management purposes. We have also periodically entered into forward swaps to hedge foreign currency exchange risk exposures. We do not enter into derivative instruments for speculative purposes. As of September 30, 2025 and December 31, 2024, we held 5 and 11 derivative contracts, respectively, which have each been designated as cash flow hedges under ASC 815, " Derivatives and Hedging ." The risk being hedged is the interest rate risk related to forecasted debt issuance transactions, and the benchmark interest rates used is the SOFR Rate. The unrealized gains or losses on the derivative instruments are recorded in AOCI and are reclassified to Interest expense on the Consolidated Statements of Operations during the same period in which the hedged transaction affects earnings. We estimate that $ 3.5 million will be reclassified as a reduction to Interest expense over the next 12 months for all of our outstanding cash flow hedges.

Derivative Contract Activity

During the three months ended June 30, 2025, we entered into six forward swap contracts with a notional amount totaling $ 1.0 billion (equivalent to £ 768.0 million) to hedge a planned repayment of a GBP debt borrowing. In conjunction with the repayment of the debt borrowing during the same period, we settled the forward swap contracts and recognized a gain of $ 14.4 million, which was recorded within Gain / (loss) on foreign currency exchanges on the Consolidated Statements of Operations.

During the three months ended June 30, 2025, we also terminated three interest rate swap contracts with an aggregate notional amount of $ 150.0 million in conjunction with the settlement of outstanding debt obligations on our Senior Credit Facility. We recorded a loss on termination of $ 1.3 million, which was recorded to Other income / (expense), net on the Consolidated Statements of Operations.

During the three months ended June 30, 2025, three forward swaps with a notional amount totaling $ 646.4 million (equivalent to £ 500.0 million) expired upon reaching their respective maturity dates.

During the three months ended June 30, 2025, we released net accumulated gains of $ 8.7 million from AOCI to earnings in conjunction with the settlement of the 2029 and 2033 Note Redemptions and the repayment of certain mortgage term loans. The debt instruments were previously classified as hedged transactions under ASC 815, " Derivatives and Hedging ," and the extinguishment of the related debt obligations resulted in the discontinuation of the cash flow hedge relationship. The net accumulated gains were recorded to Other income / (expense), net on the Consolidated Statements of Operations.

17. Fair Value Measurements

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

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

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical, or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets or can be corroborated by observable market data; and

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

The carrying values of cash, cash equivalents, and restricted cash, other receivables, and accounts payable approximate their fair market 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 6, "Notes and Other Receivables," and Note 7, "Collateralized Receivables and Transfers of Financial Assets," for additional information.

Notes Receivable from Real Estate Developers and Operators

Notes receivable from real estate developers and operators are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs including interest rates and counterparty performance (Level 3). The carrying values of the notes generally approximate their fair market values either due to the nature of the note and / or the note being secured primarily by underlying real estate and other collateral and / or personal guarantees. Refer to Note 6, "Notes and Other Receivables," for additional information.

Derivative Assets and Liabilities - Interest Rate Derivatives

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

Secured Debt

Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on management estimates and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 10, "Debt and Line of Credit," for additional information.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(Unaudited)

Secured borrowings on collateralized receivables - recorded at fair value and adjusted based on the same interest rates as the related collateralized receivables (Level 3). Refer to Note 7, "Collateralized Receivables and Transfers of Financial Assets," and Note 10, "Debt and Line of Credit," for additional information.

Unsecured Debt

Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 10, "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, 2025.

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, 2025 and 2024 (in millions):

Fair Value Measurements on a Nonrecurring Basis

As of September 30, 2025, 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. During the nine months ended September 30, 2025, due to a contemplated change in strategic plan for certain assets, as well as a reduction in projected future cash flows and deteriorating NOI trends for certain other assets, we recognized the following asset impairment charges (in millions, except for number of properties):


Period	Fair Value Level		Number of Properties	Segment	Asset Impairment Charges (1)			Aggregate Estimated Fair Value
Three months ended September 30, 2025	3	(2)	6	RV	$	165.0		$	22.9
Three months ended June 30, 2025	3	(3)	3	UK	$	132.7	(4)	$	8.9
Three months ended June 30, 2025	3	(3)	3	RV	$	32.2		$	86.4
Three months ended March 31, 2025	3	(5)	7	MH / RV	$	20.5		$	93.4

(1) Recorded in Asset impairments on the Consolidated Statements of Operations.

(2) 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 %.

(3) The non-recurring fair value measurement was driven by our contemplated change in strategic plan for the properties and was determined using an income 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.

(4) Recorded a deferred tax benefit of $ 29.5 million in conjunction with the impairment.

(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, 2025. As such, our estimates of fair value could differ significantly from the actual carrying value.

18. Commitments and Contingencies

Legal Proceedings - Class Action Litigation

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

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

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

Other Legal Proceedings

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

Catastrophic Event-Related Charges

Hurricanes Helene and Milton - In September and October 2024, Hurricane Helene and Hurricane Milton, respectively, made landfall in Florida and subsequently impacted several of our properties in the Southeastern and Mid-Atlantic region of the U.S. Estimated property insurance recoveries, excluding business interruption recoveries, of $ 39.5 million related to Hurricane Helene and Hurricane Milton, were recorded in Notes and other receivables, net, on the Consolidated Balance Sheets as of September 30, 2025. The table below sets forth changes in estimated property insurance recoveries, excluding business interruption recoveries (in millions):


	Nine Months Ended September 30, 2025
Total estimated insurance receivable - December 31, 2024	$	16.7
Change in estimated property insurance recoveries	33.4
Proceeds received from insurer	( 10.6 )
Total estimated insurance receivable - September 30, 2025	$	39.5

Hurricane Ian - In September 2022, Hurricane Ian primarily affected three RV properties in the Fort Myers area, comprising approximately 2,500 sites. We maintain property, casualty, flood, and business interruption insurance for our community portfolio, subject to customary deductibles and limits.

Estimated property insurance recoveries of $ 11.3 million related to Hurricane Ian, were recorded in Notes and other receivables, net, on the Consolidated Balance Sheets as of September 30, 2025. The table below sets forth changes in estimated property insurance recoveries, excluding business interruption recoveries (in millions):


	Nine Months Ended September 30, 2025
Total estimated insurance receivable - December 31, 2024	$	49.2
Change in estimated property insurance recoveries	1.4
Proceeds received from insurer	( 39.3 )
Total estimated insurance receivable - September 30, 2025	$	11.3

We are actively working with our insurance providers on claims for business interruption recoveries. During the nine months ended September 30, 2025 we received and recognized $ 10.7 million, net of deductibles, as business interruption recoveries for lost earnings from Hurricane Ian. The related communities are under redevelopment and we have gradually started to lease developed sites at these communities to customers. However, we currently cannot estimate a date when operating results will be restored to pre-hurricane levels. Our business interruption insurance policy provides for up to 60 months of coverage from the date of restoration.

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

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

19. Leases

Lessee Accounting

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

As of September 30, 2025, future minimum lease payments with our residents or customers would not exceed 12 months. We do not have any operating leases with real estate operators on our properties.

Failed Sale Leaseback

In connection with our acquisition of Park Holidays, we assumed ground lease arrangements for certain UK properties that we concluded to be failed sale-leaseback transactions under ASC 842, " Leases ." As of March 31, 2025, we maintained these ground lease arrangements for 32 UK properties. The arrangements have maturities ranging from 2117 through 2197 with an option to repurchase for £ 1.00 at the end of the term. The obligation related to the underlying ground leases has been recorded as a financial liability in Other Liabilities on the Consolidated Balance Sheets.

During the three and nine months ended September 30, 2025, we repurchased the titles to six and 27 UK properties, respectively, that were previously controlled via ground leases for cash payments of $ 101.2 million and $ 300.4 million, respectively, inclusive of taxes and fees. The ground lease terminations reduced our financial liability by $ 298.1 million in 2025. We recorded long-term lease termination gains of $ 19.2 million and $ 45.2 million, respectively, during the three and nine months ended September 30, 2025, which were recorded within Other income / (expense), net on the Consolidated Statements of Operations. In conjunction with the ground lease terminations, we recorded a receivable of $ 16.1 million for Value-added Taxes as of September 30, 2025. Our receivable for Value-added Taxes as of June 30, 2025 of $ 31.4 million was subsequently collected during the three months ended September 30, 2025. Refer to Note 22, "Subsequent Events" for additional activity subsequent to September 30, 2025.

The financial liability was $ 86.6 million and $ 355.9 million as of September 30, 2025 and December 31, 2024, respectively. The following table presents the future minimum rental payments for this financial liability as of September 30, 2025 (in millions):

20. Recent Accounting Pronouncements

Recent Accounting Pronouncements - Not Yet Adopted

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

In December 2023, the FASB issued ASU 2023-09, " Income Taxes (Topic 740): Improvements to Income Tax Disclosures ," which requires disclosure of specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, this amendment requires certain disclosure of income taxes paid disaggregated by federal, state and foreign taxes, and the amount of income taxes paid disaggregated by individual jurisdiction in which income taxes paid meet a quantitative threshold. The new guidance is intended to enhance the transparency and decision usefulness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024 and will be effective for our annual reporting for the year ending December 31, 2025. Early adoption is permitted and the amendments should be applied prospectively. We are currently evaluating the provisions of this amendment and the impact on our Consolidated Financial Statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, " Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40) ," which requires disaggregated disclosure of certain expense captions into specified categories within the footnotes to the financial statements. This ASU is effective for fiscal years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the provisions of this amendment and the impact on our Consolidated Financial Statements and related disclosures.

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 2024 Annual Report.

OVERVIEW

We are a fully integrated REIT. As of September 30, 2025, we owned and operated, directly or indirectly, or had an interest in, a portfolio of 501 developed properties located in the U.S., Canada, and the United Kingdom including 284 MH communities, 164 RV communities, and 53 UK communities.

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.

SAFE HARBOR SALE

In April 2025, we completed the initial closing of the Safe Harbor Sale, which generated approximately $5.25 billion of pre-tax cash proceeds, net of transaction costs, with a gain on sale of $1.4 billion. Pursuant to the terms of the transaction agreement, 15 Delayed Consent Subsidiaries representing approximately $250.0 million of value were not part of the initial closing. Subsequent to the initial closing through June 30, 2025, we completed the sale of six Delayed Consent Subsidiaries for $136.7 million. On August 29, 2025, we completed the sale of the remaining nine Delayed Consent Subsidiaries for $117.5 million and fully divested our investment in the Safe Harbor business.

The Safe Harbor Sale accelerates our strategy of focusing on our core MH and RV segments and significantly enhances our leverage profile and financial flexibility. Since the closing of the Safe Harbor Sale, we have deployed the cash proceeds from the Safe Harbor Sale to implement a balanced, tax-efficient capital allocation plan aimed at optimizing shareholder value through significantly lower leverage, greater financial flexibility to drive sustainable cash flow growth, and a thoughtful capital return strategy.

Refer to Part 1, Item 1A, "Risk Factors – Risks Related to the Safe Harbor Sale" in our Annual Report on Form 10-K for the year ended December 31, 2024, Note 2, "Assets Held for Sale and Discontinued Operations," in our accompanying Consolidated Financial Statements for additional details related to the Safe Harbor Sale.

Chief Executive Officer Transition

Charles D. Young began serving as the our Chief Executive Officer and as a Director on October 1, 2025 . Mr. Young succeeds Gary Shiffman, who previously announced his retirement from the role of CEO after a distinguished 40 years leading Sun Communities. The Company and Mr. Young entered into an employment agreement under which Mr. Young 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.

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, 2024.

SUN COMMUNITIES, INC.

NON-GAAP FINANCIAL MEASURES

In addition to the results reported in accordance with GAAP in our "Results of Operations" below, we have provided information regarding net operating income ("NOI") and funds from operations ("FFO") as supplemental performance measures. We believe NOI and FFO are appropriate measures given their wide use by and relevance to investors and analysts following the real estate industry. NOI provides a measure of rental operations and does not factor in depreciation, amortization, and non-property specific expenses such as general and administrative expenses. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation / amortization of real estate assets. In addition, NOI, and FFO are commonly used in various ratios, pricing multiples / yields and returns, and valuation calculations used to measure financial position, performance, and value.

NOI

Total Portfolio NOI - NOI is derived from property operating revenues minus property operating expenses and real estate taxes. NOI is a non-GAAP financial measure that we believe is helpful to investors as a supplemental measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. We use NOI as a key measure when evaluating performance and growth of particular properties and / or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense, and non-property specific expenses such as general and administrative expenses, all of which are significant costs. Therefore, NOI is a measure of the operating performance of our properties rather than of the Company overall. We believe that NOI provides enhanced comparability for investor evaluation of 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 cash flow from operating activities as a measure of our liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions. Because of the inclusion of items such as interest, depreciation, and amortization, the use of GAAP net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level.

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.

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.

SUN COMMUNITIES, INC.

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

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

Seasonality of Revenue

The RV 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. During the nine months ended September 30, 2025, we recognized aggregate Real property - transient revenue from our segments of $30.5 million in the first quarter, $81.4 million in the second quarter and $133.5 million in the third quarter.

During the year ended December 31, 2024, we recognized Real property - transient revenue as follows:


	Real property - transient revenue (in millions)		During the Three Months Ended

Real Property Operations - North America Same Property Portfolio

Same Property data includes all properties that we have owned and operated continuously since January 1, 2024, exclusive of properties recently completed or under construction, acquired properties, properties classified as discontinued operations, other properties as determined by management, 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. In order to evaluate the growth of the Same Property portfolio, management has classified certain items differently than our GAAP statement. 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. Additionally, prior period Canadian currency figures have been translated at 2025 average exchange rates for constant currency comparability.

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, 2025 and 2024 (in millions, except for statistical information):

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 Safe Harbor Sale, draws on our senior credit facility, and the use of debt and equity offerings under our shelf registration statement.

We take a disciplined approach to selecting the optimal mix of financing sources to meet our liquidity demands and minimize our overall cost of capital. During the three months ended June 30, 2025, we completed the initial closing of the Safe Harbor Sale, which generated pre-tax cash proceeds of approximately $5.25 billion, net of transaction costs. Subsequent to the initial closing through August 29, 2025, we completed the sale of 15 Delayed Consent Subsidiaries for $254.2 million and fully divested our investment in the Safe Harbor business. The Safe Harbor Sale advances our strategy of focusing on our core MH and RV segments and enhances our leverage profile and financial flexibility. We have deployed 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. 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 controlling 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 recognize the headwinds we are facing from a challenging macroeconomic environment and are re-aligning our strategy to focus on our proven, durable income streams. We are positioned for ongoing organic growth with expected rental rate increases, occupancy gains, and expense management. For the remainder of 2025, 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.

In connection with cash proceeds generated from the Safe Harbor Sale, through September 30, 2025, we initiated the following capital allocation decisions:

• Repaid approximately $3.3 billion of debt, including $1.6 billion of outstanding borrowings under our senior credit facility, as well as $737.7 million in secured mortgage debt, and $956.5 million in unsecured notes, inclusive of prepayment costs.

• Returned capital to shareholders, including the payment of a special cash distribution of $4.00 per share, totaling $521.3 million, and the initiation of our Stock Repurchase Program.

• Repurchased 4.0 million shares of our common stock at an average cost of $125.74 per share for a total of $500.3 million.

• Targeted reinvestment in strategic growth by allocating $629.5 million into 1031 exchange escrow accounts to fund potential future MH and RV acquisitions. Refer to the "Acquisitions, Dispositions, Development, and Expansion Activities" section below for acquisitions that closed subsequent to September 30, 2025.

• Initiated other opportunistic financial enhancements, including deploying cash of $323.6 million to repurchase the titles to 28 UK properties that were previously controlled via ground leases through October 30, 2025. We have also contractually agreed to repurchase the titles to an additional five UK properties for approximately $63.0 million, which we expect to close by the end of the first quarter of 2026.

Refer to Note 1, "Basis of Presentation," and Note 2, "Assets Held for Sale and Discontinued Operations," for additional details related to the Safe Harbor Sale. Refer to Note 19, "Leases," for additional details related to the UK long-term lease terminations. Refer to Note 21, "Subsequent Events," for additional details related to acquisitions that closed subsequent to September 30, 2025.

Acquisitions, Dispositions, Development, and Expansion Activities

Subject to market conditions, we intend to selectively identify opportunities to expand our development pipeline and acquire existing properties. We finance acquisitions through available cash, secured financing, draws on our senior credit facility, the assumption of existing debt on properties, and the issuance of debt and equity securities. As of September 30, 2025, we had allocated restricted cash of $629.5 million into 1031 exchange escrow accounts to fund potential future MH and RV acquisitions. In October 2025, we acquired 11 MH and three RV properties for total cash consideration of $457.0 million. Given the higher interest rate environment, we continue to selectively pursue acquisition and development opportunities that meet our underwriting criteria.

SUN COMMUNITIES, INC.

We have continued a targeted disposition program to divest non-strategic assets in an effort to simplify management and maintain financial flexibility. During the nine months ended September 30, 2025, we sold three MH properties, three RV properties, and one MH and one RV development land parcel for a gross sale price of approximately $182.2 million.

We plan to selectively expand our properties utilizing our inventory of owned and entitled land. We have 15,860 MH and RV sites suitable for future development. Refer to Note 5, "Real Estate Acquisitions and Dispositions," in our accompanying 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, 2025		September 30, 2024
Net Cash Provided By Operating Activities	$	641.3	$	550.0
Net Cash Provided By / (Used For) Investing Activities	$	(127.9)	$	22.8
Net Cash Provided By / (Used For) Financing Activities	$	606.4	$	(542.7)

Cash, cash equivalents and restricted cash increased by $1.1 billion from $57.1 million as of December 31, 2024, to $1.2 billion as of September 30, 2025.

Operating activities - Net cash provided by operating activities increased by $91.3 million to $641.3 million for the nine months ended September 30, 2025, compared to $550.0 million for the nine months ended September 30, 2024. The increase in operating cash flow was primarily due to growth in Same Property operating performance at our MH and UK properties, partially offset by the timing of changes in inventory, other assets, and other liabilities, and reduced operating performance at our RV properties during the nine months ended September 30, 2025 as compared to the corresponding period in 2024.

SUN COMMUNITIES, INC.

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 2024 Annual Report, and Part II, Item 1A of our Quarterly Report on Form 10-Q for the three months ended March 31, 2025.

Investing activities - Net cash used for investing activities was $127.9 million for the nine months ended September 30, 2025, compared to net cash provided by investing activities of $22.8 million for the nine months ended September 30, 2024. The change in Net cash provided by / (used for) investing activities was primarily driven by a decrease in proceeds received from the disposition of MH and RV properties, and partially offset by the settlements of notes receivable from real estate developers during the nine months ended September 30, 2025 as compared to the corresponding period in 2024.

Financing activities - Net cash provided by financing activities was $606.4 million for the nine months ended September 30, 2025, compared to net cash used for financing activities of $542.7 million for the nine months ended September 30, 2024. The change in Net cash provided by / (used for) financing activities was primarily driven by a net capital transfer of $5.5 billion from Safe Harbor to the Company in conjunction with the Safe Harbor Sale, partially offset by an increase in cash deployed to settle debt obligations and distribute cash to shareholders through share repurchases and a special cash dividend paid in May 2025 during the nine months ended September 30, 2025 as compared to the corresponding period in 2024. Refer to Note 10, "Debt and Line of Credit," and Note 11, "Equity and Temporary Equity," in our accompanying Consolidated Financial Statements for additional information.

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


	Nine Months Ended
	September 30, 2025		September 30, 2024
Net cash provided by operating activities - discontinued operations	$	56.4	$	193.0
Net cash provided by / (used for) investing activities - discontinued operations	$	5,511.9	$	(188.4)
Net cash provided by / (used for) financing activities - discontinued operations	$	(5,573.5)	$	3.8

Cash, cash equivalents and restricted cash for discontinued operations decreased by $6.8 million from $6.8 million as of December 31, 2024, to zero as of September 30, 2025.

Operating activities - Net cash provided by operating activities for discontinued operations decreased by $136.6 million to $56.4 million for the nine months ended September 30, 2025, compared to $193.0 million for the nine months ended September 30, 2024. The decrease in net cash provided by operating activities for discontinued operations was due to a reduction in owned marinas, due to the closing of the Safe Harbor Sale during the nine months ended September 30, 2025 as compared to the corresponding period in 2024.

Investing activities - Net cash provided by investing activities for discontinued operations was $5.5 billion for the nine months ended September 30, 2025, compared to net cash used for investing activities for discontinued operations of $188.4 million for the nine months ended September 30, 2024. The change in net cash provided by / (used for) investing activities for discontinued operations is driven by cash proceeds received from the closing of the Safe Harbor Sale.

Financing activities - Net cash used for financing activities for discontinued operations was $5.6 billion for the nine months ended September 30, 2025, compared to net cash provided by financing activities for discontinued operations of $3.8 million for the nine months ended September 30, 2024. The change in net cash provided by / (used for) financing activities for discontinued operations is driven by the net capital transfer of $5.5 billion from Safe Harbor to the Company in conjunction with the Safe Harbor Sale.

SUN COMMUNITIES, INC.

Refer to the Consolidated Statements of Cash Flows for detail on the net cash used for financing activities for discontinued operations during the nine months ended September 30, 2025 and 2024. Refer to Note 2, "Assets Held for Sale and Discontinued Operations," in our accompanying Consolidated Financial Statements for additional information.

The absence of future cash flows from discontinued operations is not expected to significantly impact our liquidity, as the cash proceeds from the Safe Harbor Sale have been allocated to pay down debt, which will generate annualized interest expense savings, and to reinvest in our core MH and RV segments by means of a $629.5 million cash allocation to 1031 exchange escrow accounts as of September 30, 2025. Subsequent to the nine months ended September 30, 2025, we allocated $399.0 million of restricted cash from the 1031 exchange escrow account and $58.0 million of unrestricted cash to acquire 11 MH and three RV communities. Refer to Note 21, "Subsequent Events," for more 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, 2025, approximately 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, 2025, 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 2025, 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 April 30, 2026. Under the Stock Repurchase Program, we may repurchase shares of our common stock 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 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.

All repurchased shares are retired and returned to authorized but unissued status upon settlement. Through September 30, 2025, we repurchased and retired 4.0 million shares of our outstanding common stock for $500.3 million. As of September 30, 2025, we had $499.7 million remaining authorized for purchase under this program.

Total	$	2,700.0	$	1,785.9	$	2,676.3

During the three months ended June 30, 2025, we redeemed the aggregate principal amount of $900.0 million on the 2029 Notes and the 2033 Notes using cash proceeds generated from the Safe Harbor Sale. In accordance with the terms of each series of Notes, the redemption price was inclusive of a customary make-whole premium and accrued and unpaid interest. As a result, during the three months ended June 30, 2025, we recorded charges of $56.5 million to Loss on extinguishment of debt on the Consolidated Statements of Operations in connection with early extinguishment premiums on the 2029 and 2033 Note Redemptions. Refer to Note 16, "Derivative Financial Instruments," for cash flow hedge activity resulting from the redemptions.

SUN COMMUNITIES, INC.

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.

New Credit Agreement

On September 17, 2025, we entered into the New Credit Agreement, which replaced our previous $3.05 billion senior credit facility.

Pursuant to the New Credit Agreement, we may borrow up to $2.0 billion under the New Credit Facility. The New Credit Agreement also permits, subject to the satisfaction of certain conditions, additional borrowings of $1.0 billion. The New 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.

The New Credit Facility offers various interest rates for borrowings under U.S. dollars (at the ABR, Term SOFR, and Daily Effective SOFR), euros (at the Adjusted EURIBOR), pound sterling (at the Daily Simple SONIA Rate), Canadian dollars (at the Term CORRA) and the Daily Simple CORRA), and Australian dollars (at the Australian BBSY Rate,) plus a margin which can range from 0.725% to 1.40% for all interest rates except ABR loans, which can range from 0.000% to 0.400%. As of September 30, 2025, there were no borrowings under the New Credit Facility.

During the three months ended September 30, 2025, we recorded charges of $1.6 million to Loss on extinguishment of debt on the Consolidated Statements of Operations related to the write off of deferred financing costs in connection with the termination of our previous senior credit facility. As of September 30, 2025, we also recorded deferred financing costs of $11.4 million in connection with the New Credit Facility, which was recorded within Other assets, net on the Consolidated Balance Sheets.

The New Credit Facility provides us with the ability to issue up to $100.0 million of letters of credit. We had $10.3 million and $11.5 million of outstanding letters of credit at September 30, 2025 and December 31, 2024, respectively.

SUN COMMUNITIES, INC.

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, 2025 we had unrestricted cash on hand of $542.7 million, $2.0 billion of remaining capacity on the senior credit facility, and a total of 391 unencumbered MH, RV, and UK properties.

From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, issue unsecured notes, obtain other debt financing, or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the MH 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 2024 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, 2025, our net debt to enterprise value was 18.3% (assuming conversion of all common and preferred OP units to shares of common stock). Our debt has a weighted average interest rate of 3.38% and a weighted average maturity of 7.4 years.

Capital Requirements

Certain of our nonconsolidated affiliates, which are accounted for under the equity-method of accounting, have incurred debt. We have not guaranteed the debt of our nonconsolidated affiliates in the arrangements referenced below, nor do we have any obligations to fund this debt should the nonconsolidated affiliates be unable to do so. Refer to Note 9, "Investments in Nonconsolidated Affiliates," in the accompanying Consolidated Financial Statements for additional information about these entities.

GTSC - GTSC maintains a warehouse line of credit with a maximum borrowing capacity of $275.0 million. As of September 30, 2025 and December 31, 2024, the aggregate carrying amount of debt, including both our and our partner's share, incurred by GTSC was $220.0 million (of which our proportionate share is $88.0 million), and $242.9 million (of which our proportionate share is $97.1 million), respectively. The debt bears interest at a variable rate based on a Commercial Paper or adjusted SOFR plus a margin ranging from 1.65% to 2.5% per annum and matures on December 15, 2026.

Sungenia JV - Sungenia maintains a debt facility agreement with a maximum borrowing capacity of $54.1 million Australian dollars, or $35.8 million converted at the September 30, 2025 exchange rate. As of September 30, 2025 and December 31, 2024, the aggregate carrying amount of the debt, including both our and our partners' share, incurred by Sungenia JV was $24.6 million (of which our proportionate share is approximately $12.3 million), and $25.0 million (of which our proportionate share is $12.5 million), respectively. The debt bears interest at a variable rate based on the Australian BBSY rate plus a margin ranging from 0.95% to 1.4%, subject to adjustment for additional future commitments, per annum and matures on June 30, 2027.

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, 2025, 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.

Foreign Currency Exchange Rate Risk

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

At September 30, 2025 and December 31, 2024, our shareholder's equity included $1.0 billion and $672.3 million from our investments and operations in the United Kingdom, Canada, and Australia which collectively represented 14.2% and 9.3% of total shareholder's equity, respectively. Based on our sensitivity analysis, a 10.0% strengthening of the U.S. dollar against the pound sterling, Canadian dollar, and Australian dollar would have caused a reduction of $103.2 million and $67.2 million to our total shareholder's equity at September 30, 2025 and December 31, 2024, respectively.

Capital Market Risk

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

ITEM 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. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period was made under the supervision and with the participation of our management, including our principal executive officer and principal financial officer.

Based upon this evaluation, our principal executive officer and principal financial officer have concluded that, as of September 30, 2025, our disclosure controls and procedures were not effective as of that date due to a material weakness in internal control over financial reporting relating to our risk assessment process, as described below.

Material Weaknesses in Internal Control Over Financial Reporting

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

As described in Part II, Item 9A "Controls and Procedures" of our 2024 Annual Report, as of December 31, 2024, management identified a material weakness because we did not have an effective risk assessment and response process ("risk assessment") that defined clear financial reporting objectives, that identified and evaluated risks of misstatement due to errors over certain financial reporting processes, or that developed internal controls to mitigate those risks.

Remediation of Material Weaknesses

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

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

Changes in internal control over financial reporting

Except as discussed in the preceding paragraph, there were no changes in internal control over financial reporting during the three months ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Legal Proceedings

We are involved in various legal proceedings. Refer to "Legal Proceedings - Class Action Litigation" and "Other Legal Proceedings" in Part I - Item 1 - Note 18, "Commitments and Contingencies," in our accompanying Notes to the Consolidated Financial Statements.

Environmental Matters

Item 103 of Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions that we reasonably believe will exceed an applied threshold not to exceed $1.0 million. Applying this threshold, there are no environmental matters to disclose for the three months ended September 30, 2025.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors described in Part 1, Item 1A., "Risk Factors," in our 2024 Annual Report and Part II, Item 1A., "Risk Factors," in our Quarterly Report on Form 10-Q for the three months ended March 31, 2025, which could materially affect our business, financial condition, or future results. There have been no material changes to the disclosure on these matters as set forth in such report.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

(1) During the three months ended September 30, 2025, we withheld 449 shares from employees to satisfy estimated statutory income tax obligations related to vesting of restricted stock awards. The value of the common stock withheld was based on the closing price of our common stock on the applicable vesting date.

(2) In April 2025, we announced by press release that 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 April 30, 2026. Under the Stock Repurchase Program, we may repurchase shares of our common stock 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 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. Refer to Note 11, "Equity and Temporary Equity," for additional information regarding our Stock Repurchase Program.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

ITEM 5. OTHER INFORMATION

During the three months ended September 30, 2025, none of our officers or directors, as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934, adopted , modified, or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement, as defined in Item 408 of Regulation S-K.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law. The OBBBA made significant changes to the U.S. federal income tax laws in various areas. Among the notable changes, the OBBBA permanently extended certain provisions that were enacted in the Tax Cuts and Jobs Act of 2017, most of which were set to expire after December 31, 2025. As a result of such extensions, individuals and other non-corporate taxpayers will continue to be entitled to a 20% deduction for certain "qualified REIT dividends" for taxable years after 2025, subject to certain requirements, and the maximum U.S. federal income tax rate on ordinary income for individuals and other non-corporate taxpayers will continue to be 37% after 2025 (before application of the 3.8% Medicare tax on "net investment income"). In addition, the OBBBA also increased the percentage limit under the REIT asset test applicable to securities of one or more taxable REIT subsidiaries from 20% to 25% for 2026 and subsequent taxable years. You are urged to consult with your own tax advisor to determine the effects of the OBBBA and the ownership and disposition of our securities or debt securities of the Operating Partnership on your individual tax situation, including any state, local, or non-U.S. tax consequences.
