Definitions and Notes Acquisition and Other Transaction Costs - In the Company’s Reconciliation of Net Income / (Loss) Attributable to SUI Common Shareholders to Core FFO on page 5, “Acquisition and other transaction costs - continuing operations” represent (a) nonrecurring integration expenses associated with acquisitions during the quarters and nine months ended September 30, 2026 and 2025, (b) costs associated with potential acquisitions that will not close, (c) expenses incurred to bring recently acquired properties up to the Company’s operating standards, including items such as tree trimming and painting costs that do not meet the Company’s capitalization policy, and (d) other non-recurring transaction costs. Within this same reconciliation on page 5, “Acquisition and other transaction costs - discontinued operations” primarily represent non-recurring transaction costs that are directly attributable to the Park Holidays Sale and the Safe Harbor Sale and nonrecurring integration expenses associated with previous UK and marina acquisitions. Adjusted Blended Occupancy - Occupancy percentage after adjusting for recently delivered and vacant expansion sites. Asset Impairments - In the Company’s Condensed Consolidated Statements of Operations on page 4, the Company recorded asset impairment charges of $17.2 million for the quarter ended September 30, 2026, primarily consisting of charges to reduce the carrying value of one RV property in Texas, driven by a reduction in projected future cash flows for the impaired property. Capital Expenditures - The Company classifies its investments in properties into the following categories: • Recurring Capital Expenditures - Property recurring capital expenditures are necessary to maintain asset quality, including purchasing and replacing items used to operate the communities. Recurring capital expenditures at the Company’s MH and RV properties include major road, driveway and pool improvements; clubhouse renovations; adding or replacing streetlights; playground equipment; signage; maintenance facilities; manager housing and property vehicles. The minimum capitalized amount is one thousand dollars. • Non-Recurring Capital Expenditures - The following investment and reinvestment activities are non-recurring in nature: • Lot Modifications - consist of expenditures incurred to modify the foundational structures required to set up a new home after a previous home has been removed. These expenditures are necessary to create a revenue stream from a new site renter and often improve the quality of the community. Other lot modification expenditures include land improvements added to annual RV sites to aid in the conversion of transient RV guests to annual contracts. See page 10 for move-out rates. • Growth Projects - consist of revenue-generating or expense-reducing activities at the properties. These include, but are not limited to, utility efficiency and renewable energy projects, site, or amenity upgrades, such as the addition of a garage or shed, and other special capital projects that substantiate an incremental rental increase. • Capital Improvements to Recent Acquisitions - represents capital improvements identified during due diligence from the acquisition date through the third year of ownership needed to bring acquired properties up to the Company’s operating standards. Capital improvements subsequent to acquisition often require 24 to 36 months to complete after closing. At MH and RV properties, capital improvements include upgrading clubhouses; landscaping; new street lighting systems; new mail delivery systems; pool renovations including larger decks, heaters and furniture; new maintenance facilities; lot modifications; and new signage including main signs and internal road signs. • Expansions and Developments - consist primarily of construction costs such as roads, activities, and amenities, and costs necessary to complete site improvements, such as driveways, sidewalks, and landscaping at the Company’s MH and RV communities. Expenditures also include costs to rebuild after damage has been incurred at MH or RV properties. Cash, Cash Equivalents and Restricted Cash - Includes cash and cash equivalents of $40.4 million as of September 30, 2026, that was held in escrow accounts and restricted from general use. Discontinued Operations: Park Holidays Sale - In May 2026, the Company entered into an agreement to sell Park Holidays, which represents a strategic shift in operations that will have a major effect on the Company’s operations and financial results. 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. 3rd Quarter Supplemental Information, Unaudited 14

As previously reported, during the quarter ended June 30, 2026, the Company recorded a non-cash valuation allowance of $1.1 billion against the assets held for sale to reduce the carrying value of the UK business to the estimated fair value less costs to sell. During the quarter ended September 30, 2026, the Company recorded an increase to the valuation allowance and loss on disposal of $50.6 million. Each respective change to the valuation allowance was recorded within Income / (loss) from discontinued operations, net on the Company’s Condensed Consolidated Statements of Operations.

For its presentation of Same Property results on page 9, the Company nets the following utility revenues (which include utility reimbursement revenues from residents) against related utility expenses in Same Property operating expenses (in millions): Quarter Ended September 30, Nine Months Ended September 30, Same Property Portfolio 2026 2025 2026 2025 Utility revenues netted against related utility expenses MH $ 21.4 $ 20.0 $ 61.3 $ 57.1 RV 6.8 6.7 16.8 16.3 Total $ 28.2 $ 26.7 $ 78.1 $ 73.4 Non-GAAP Supplemental Measures Investors and analysts following the real estate industry use non-GAAP supplemental performance measures, including net operating income (“NOI”), Net Debt, earnings before interest, tax, depreciation, and amortization for real estate (“EBITDAre”), and funds from operations (“FFO”) to assess REITs. The Company believes that NOI, EBITDAre, Net Debt, and FFO are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, these non-GAAP measures are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations that measure financial position, performance, and value. 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. EBITDAre provides a further measure to evaluate the Company’s ability to incur and service debt; EBITDAre also provides further measures to evaluate the Company’s ability to fund dividends and other cash needs. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets. • Net Operating Income (“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 the Company believes 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. The Company uses 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 the properties of the Company rather than of the Company overall. The Company believes that NOI provides enhanced comparability for investor evaluation of property performance and growth over time. The Company believes 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 the Company’s financial performance or GAAP net cash provided by operating activities as a measure of the Company’s liquidity; nor is it indicative of funds available for the Company’s cash needs, including its 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 performance and growth of the Company’s Same Property portfolio. Same Property NOI does not include the revenues and expenses related to home sales and ancillary activities at the properties. The Company believes 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. • Earnings before interest, tax, depreciation and amortization for real estate (“EBITDAre”) • EBITDAre - Nareit calculates “EBITDAre” as GAAP net income (loss), plus interest expense, plus income tax expense, plus depreciation and amortization, plus or minus losses or gains on the disposition of depreciated property (including losses or gains on change of control), plus impairment write-downs of depreciated property and of investments in nonconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, and adjustments to reflect the entity’s share of EBITDAre of nonconsolidated affiliates. EBITDAre is a non-GAAP financial measure that the Company uses to evaluate its ability to incur and service debt, fund dividends and other cash needs, and cover fixed costs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. 3rd Quarter Supplemental Information, Unaudited 19

• Recurring EBITDAre - The Company also uses EBITDAre excluding certain gain and loss items that management considers unrelated to measurement of the Company’s performance on a basis that is independent of capital structure (“Recurring EBITDAre”). The Company believes that GAAP net income (loss) is the most directly comparable measure to EBITDAre. EBITDAre is not intended to be used as a measure of the Company’s cash generated by operations or its dividend-paying capacity, and should therefore not replace GAAP net income (loss) as an indication of the Company’s financial performance or GAAP cash flow provided by / used for operating, investing, and financing activities as measures of liquidity. • Funds from Operations (“FFO”) • FFO - Nareit defines FFO 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 the Company’s 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, the Company uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of the Company’s 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. The Company believes that FFO and Core FFO provide enhanced comparability for investor evaluations of period-over-period results. The Company believes 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 the Company’s 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 the Company’s 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. 3rd Quarter Supplemental Information, Unaudited 20
