Definitions and Notes

Acquisition and Other Transaction Costs - In the Company's Reconciliation of Net Loss Attributable to SUI Common Shareholders to Core FFO on page 6, 'Acquisition and other transaction costs' represent (a) nonrecurring integration expenses associated with acquisitions during the quarters ended March 31, 2024 and 2023, (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 other non-recurring transaction costs, and (d) other non-recurring transactions.

Capital Expenditures and Investment Activity - 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 and marinas. Recurring capital expenditures at the Company's MH, RV and UK properties include major road, driveway and pool improvements; clubhouse renovations; adding or replacing streetlights; playground equipment; signage; maintenance facilities; manager housing and property vehicles. Recurring capital expenditures at the marinas include dredging, dock repairs and improvements, and equipment maintenance and upgrades. The minimum capitalized amount is five hundred dollars.

•Non-Recurring Capital Expenditures - The following investment and reinvestment activities are non-recurring in nature:

•Lot Modifications - Lot modification capital expenditures are incurred to modify the foundational structures required to set 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 13 for move-out rates.

•Growth Projects - 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, slip or amenity upgrades, such as the addition of a garage, shed or boat lift, and other special capital projects that substantiate an incremental rental increase.

•Rebranding - Rebranding includes new signage at the Company's RV communities and costs of building an RV mobile application and updated website.

•Acquisitions - Total acquisition investments represent the purchase price paid for operating properties (detailed for the current calendar year on page 14), the purchase price paid for land parcels for future ground-up development and expansions activities, and any capital improvements identified during due diligence 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, RV and UK properties, capital improvements include upgrading clubhouses; landscaping; new street light 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. Capital improvements at Marina properties primarily include improvements to rooms, renovation of restaurant facilities, pools and fitness centers.

For the quarter ended March 31, 2024, the components of total acquisition investment are as follows (in millions):

The Same Property data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions or unique situations.

Secured borrowings on collateralized receivables - This is a transferred asset transaction which has been classified as collateralized receivables and the cash received from this transaction has been classified as secured borrowings. The interest income and interest expense accrue at the same amount. The Company elected to fair value the collateralized receivables and the secured borrowings under ASC 820, "Fair Value Measurements and Disclosures." As a result, the balance of collateralized receivables and related secured borrowings are net of fair value adjustments.

Securities - The Company had the following securities outstanding as of March 31, 2024:

Non-GAAP Supplemental Measures

Investors and analysts following the real estate industry use non-GAAP supplemental performance measures, including net operating income ("NOI"), earnings before interest, tax, depreciation and amortization ("EBITDA") and funds from operations ("FFO") to assess REITs. The Company believes that NOI, EBITDA and FFO are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, NOI, EBITDA 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 provides a measure of rental operations that does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses.

1st Quarter Supplemental Information 23

EBITDA provides a further measure to evaluate ability to incur and service debt; EBITDA 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 - The Company calculates NOI by subtracting property operating expenses and real estate taxes from operating property revenues. 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 properties 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 cash flow from 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. 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. Same Property NOI does not include the revenues and expenses related to home sales, service, retail, dining and entertainment activities at the properties.

•Earnings before interest, tax, depreciation and amortization ("EBITDA")

◦EBITDAre - Nareit refers to EBITDA as "EBITDAre" and calculates it 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.

◦Recurring EBITDA - 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 EBITDA"). 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 from operating, investing and financing activities as measures of liquidity.

1st Quarter Supplemental Information 24

•Funds from Operations ("FFO")

◦FFO - Nareit defines FFO 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 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"). The Company believes that Core FFO provides 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.
