Net income attributable to common shareholders was $0.7 million, or $0.01 per diluted common share, compared to net income attributable to common shareholders of $24.8 million, or $0.23 per diluted common share, for the same period in 2021.

Non-GAAP Financial Measures and Portfolio Performance

•Core Funds from Operations ("Core FFO")(1)for the quarter ended March 31, 2022, was $1.34 per diluted share and OP unit ("Share") as compared to $1.26 in the corresponding period in 2021, a 6.3 percent increase.

•Same Property(2) Net Operating Income ("NOI")(1) for the Company's MH and RV properties increased by 7.7 percent for the quarter ended March 31, 2022, as compared to the corresponding period in 2021.

•Same Property(2) NOI for the Company's marina properties increased by 1.2 percent for the quarter ended March 31, 2022, as compared to the corresponding period in 2021.

•Acquisitions totaled $1.6 billion during and subsequent to the quarter ended March 31, 2022, including 41 properties in the United Kingdom ("UK") and four marinas in the United States.

"Our strong first quarter performance builds on the momentum of last year as we delivered 6.3 percent growth in Core FFO per Share," said Gary A. Shiffman, Chairman and CEO. "With sustained tailwinds, the demand for attainable housing and outdoor vacationing continues to reach new levels, and with our best-in-class offering, Sun is uniquely positioned to meet these customer needs. We are pleased to have completed the acquisition of Park Holidays and already have a growing pipeline of acquisition opportunities in the UK. Furthermore, we have been active in the capital markets as we amended and upsized our Senior Credit Facility, issued $600 million of senior notes with a favorable rate lock, and settled forward equity sale agreements, all of which enhanced our balance sheet position. Over the years, Sun has delivered consistent and cycle tested organic cash flow growth, and today the number of compelling investment opportunities is more exciting than ever across our MH, RV and marina platforms."

BALANCE SHEET, CAPITAL MARKETS ACTIVITY AND OTHER ITEMS

Debt

As of March 31, 2022, the Company had approximately $6.1 billion in debt outstanding. The weighted average interest rate was 3.0 percent and the weighted average maturity was 8.1 years. At March 31, 2022, the Company's net debt to trailing twelve month Recurring EBITDA(1) ratio was 5.9 times. The Company had $90.4 million of unrestricted cash on hand.

Senior Credit Facility Amendment

On April 7, 2022, in conjunction with the closing of the Park Holidays acquisition, Sun Communities Operating Limited Partnership (the "Operating Partnership") as borrower, and the Company, as guarantor, and certain lenders entered into Amendment No. 1 to the Fourth Amended and Restated Credit Agreement and Other Loan Documents (the "Credit Facility Amendment"), which amended the Operating Partnership's Senior Credit Facility.

The Credit Facility Amendment increased the aggregate amount of the Operating Partnership's Senior Credit Facility to $4.2 billion with the ability to upsize the total borrowings by an additional $800 million, subject to certain conditions. The increased aggregate amount under the Senior Credit Facility consists of the following: (a) a revolving loan in the amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, Pounds sterling, Euros, Canadian dollars and Australian dollars, subject to certain limitations. The Credit Facility Amendment extends the maturity date of the revolving loan facility to April 7, 2027, assuming the Operating Partnership's exercise of each of its two six-month extension options, and, further, the Credit Facility Amendment extends the maturity date of the term loan facility to April 7, 2025, which may not be extended.

Prior to the amendment, the Senior Credit Facility permitted aggregate borrowings of up to $2.0 billion, with an accordion feature that allowed for additional commitments of up to $1.0 billion, subject to the satisfaction of certain conditions.

The Senior Credit Facility bears interest at a floating rate based on Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Daily RFR Rate, the Australian Bank Bill Swap Bid Rate (BBSY), the Daily SONIA Rate or the Canadian Dollar Offered Rate, as applicable, plus, in all cases, a margin which can range from 0.725 percent to 1.6 percent, subject to certain adjustments. As of March 31, 2022, the margin based on the Operating Partnership's credit ratings would have been 0.85 percent on the revolving loan facility and 0.95 percent on the term loan facility.

Senior Unsecured Notes

On April 12, 2022, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 4.2 percent and a 10-year term, due April 15, 2032 (the "2032 Notes"). The net proceeds from the offering were $592.3 million after deducting underwriters' discounts and estimated offering expenses. The Company used the net proceeds from the offering to repay borrowings outstanding under its Senior Credit Facility.

iv

In connection with the 2032 Notes issuance, the Company settled four 10-year Treasury rate locks totaling $600.0 million and received a settlement payment of $35.3 million. This lowers the effective interest rate on the 2032 Notes from 4.2 percent to 3.6 percent.

Equity Transactions

Forward Share Settlements

In April 2022, the Company settled forward sale agreements with respect to 1,200,000 shares of common stock under its at the market offering sales program sold during the fourth quarter 2021, and 4,025,000 shares of common stock in connection with its November 2021 registered forward equity offering. The aggregate net proceeds from the settlement of these forward sale agreements was $934.9 million. The Company used the net proceeds to repay borrowings outstanding under its Senior Credit Facility.

Footnotes and Definitions

(1)Investors in and analysts following the real estate industry utilize funds from operations ("FFO"), net operating income ("NOI"), and earnings before interest, tax, depreciation and amortization ("EBITDA") as supplemental performance measures. The Company believes that FFO, NOI and EBITDA are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, FFO, NOI and EBITDA are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations used to measure financial position, performance and value.

•FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of generally accepted accounting principles ("GAAP") depreciation and amortization of real estate assets.

•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.

•EBITDA provides a further measure to evaluate ability to incur and service debt and to fund dividends and other cash needs.

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 depreciable operating property, plus real estate related depreciation and amortization, real estate related impairments, 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, impairment and excluding 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. The Company also uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our 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 performance measure or GAAP cash flow from operations as a liquidity measure. 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.

NOI is derived from 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 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.

EBITDA as defined by NAREIT (referred to as "EBITDAre") is calculated 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.

1st Quarter 2022 Supplemental Information 25 Sun Communities, Inc.

Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. 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.

(2)Same Property results for our MH and RV properties reflect constant currency for comparative purposes. Canadian currency figures in the prior comparative period have been translated at 2022 average exchange rates.

(3)The Same Property MH and RV blended occupancy for 2022 is derived from 124,118 developed sites, of which 121,526 were occupied. The Same Property adjusted MH and RV blended occupancy percentage is derived from 123,346 developed sites, of which 121,526 were occupied. The number of developed sites excludes RV transient sites and nearly 1,100 recently completed but vacant MH expansion sites.

The Same Property adjusted MH and RV blended occupancy percentage for 2021 has been adjusted to reflect incremental period-over-period growth from newly rented expansion sites and the conversion of transient RV sites to annual RV sites.

(4)The effect of certain anti-dilutive convertible securities is excluded from these items.
