Acquisition and Other Transaction Costs - In the Company's Reconciliation of Net 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 quarter ended March 31, 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 Safe Harbor Sale and nonrecurring integration expenses associated with previous marina acquisitions.

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, 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. 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 11 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.
- Rebranding - includes new signage at the Company's RV communities and costs of building an RV mobile application and updated website.
- 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, RV, and UK 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, RV, and UK communities. Expenditures also include costs to rebuild after damage has been incurred at MH, RV, or UK properties.

Cash, Cash Equivalents and Restricted Cash - Includes cash and cash equivalents of $14.6 million as of March 31, 2026, that was held in escrow accounts and restricted from general use. The restricted cash and cash equivalents include $9.6 million that has been designated to fund potential future MH and RV acquisitions under 1031 exchange transactions.

Discontinued Operations - In 2025, the Company entered into the Safe Harbor Sale, which represented a strategic shift in operations. Accordingly, the results of the Safe Harbor business have been reflected as discontinued operations on our Consolidated Statements of Operations through the final transaction closing date of August 29, 2025. Prior periods have been recast to reflect this presentation.

Enterprise Value - Equals total equity market capitalization, plus total indebtedness reported on the Company's balance sheet and less unrestricted cash and cash equivalents.

GAAP - U.S. Generally Accepted Accounting Principles.

Home Sales Contribution to FFO - The reconciliation of NOI from home sales to FFO from home sales for the quarter ended March 31, 2026 is as follows (in millions):

⁽¹⁾ During the quarter ended December 31, 2025, the Company received a settlement of $80.2 million from an insurance provider to settle all claims related to property, casualty, flood, and business interruption insurance recoveries from Hurricane Ian. The Company concluded that $36.5 million of the total settlement pertained to business interruption recoveries through 2027, which the Company recorded as a contingent gain per ASC 450. To better reflect the underlying economics of the transaction, the Company has elected to defer the business interruption recovery gain and recognize income ratably through 2027 for our presentation of Core FFO.

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 in equal amounts. The Company has elected to record the collateralized receivables and secured borrowings at fair value 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.

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 and does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses.

EBITDA provides a further measure to evaluate the Company's 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 - 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. For the UK segment, the Company presents Same Property NOI growth rate information on a constant currency basis to provide a framework for assessing how its underlying properties performed after excluding the effects of changes in exchange rates. The Company believes that the presentation of UK Same Property NOI on a constant currency basis helps to improve the ability to understand its performance because it excludes the effects of foreign currency volatility which are not indicative of the Company's core operating results in the region.

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 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, 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") 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.
