"A strong fourth quarter concluded an incredibly productive year for Sun Communities, where we made meaningful progress in each of our internal and external growth initiatives," said Gary A. Shiffman, Chairman and CEO. "Robust demand for the attainable housing and outdoor experiences that Sun provides resulted in compelling organic growth, driving an 11.2 percent same community NOI increase for the year, further building on our demonstrated strength throughout the pandemic. We expanded our portfolio, completing $1.4 billion of high-quality acquisitions across manufactured housing communities, RV resorts and marinas and opened four new ground-up development properties. We also continued to grow our pipeline for future growth with land purchases for greenfield development and site expansions. We are particularly excited to be entering the UK market with our announced planned acquisition of Park Holidays, a leading holiday park platform with irreplaceable seaside communities. With a proven track record of execution, accretive growth and favorable tailwinds supporting ongoing demand, we are continuing to invest in our platform in order to realize additional opportunities of accelerated growth and create shareholder value for years to come."

The net proceeds from the offering were approximately $595.5 million after deducting underwriters' discounts and estimated offering expenses.

Amended Senior Credit Facility

The Company has obtained commitments from its lender group to amend, extend and upsize its senior credit facility simultaneously with, and conditioned on, the closing of the Park Holidays Acquisition. The proposed amendment (the "Proposed Loan Amendment") would provide for borrowings on the following terms:

•Up to an aggregate of $4.2 billion in total borrowings with the ability to upsize the total borrowings by an additional $800.0 million (subject to certain conditions), an increase from the existing total borrowing limit of $2.0 billion with the ability to upsize the total borrowings by an additional $1.0 billion (subject to certain conditions);

•A revolving loan facility of up to $3.05 billion, and a term loan facility of $1.15 billion, to fund the business of the Company and all its subsidiaries;

•The ability to draw funds from the combined facilities in U.S. dollars, British pounds, Euros, Canadian dollars and Australian dollars, subject to certain limitations;

•An extension of the maturity date of the revolving loan facility to the fifth anniversary of the date of the Proposed Loan Amendment, assuming the exercise of two six-month extension options;

•A maturity date for the term loan facility of the third anniversary of the date of the Proposed Loan Amendment; and

•Interest at a floating rate based on Term SOFR, the Adjusted Eurocurrency Rate, the Australian Bank Bill Swap Bid Rate (BBSY), the Daily SONIA Rate or the Canadian Dollar Offered Rate plus a margin which can range from 0.725 percent to 1.600 percent. As of February 18, 2022, the margin based on the Company's credit ratings would have been 0.850 percent on the proposed revolving loan facility and 0.950 percent on the proposed term loan facility.

The closing of the Proposed Loan Amendment is subject to, among other things, the completion of the Park Holidays Acquisition, the negotiation and execution of definitive documentation acceptable to the Company's lender group and customary closing contingencies. There can be no assurance that the Company will be able to

vi

successfully enter into the Proposed Loan Amendment on the terms described above or at all. If the Proposed Loan Amendment is not entered into, the Company may use its previously announced £950 million bridge loan commitment entered into in November 2021 to fund all or a portion of the purchase price for the Park Holidays Acquisition.

Equity Transaction

Public Equity Offerings

In November 2021, the Company entered into two forward sale agreements (the "November 2021 Forward Sale Agreements") relating to an underwritten registered public offering of 4,025,000 shares of the Company's common stock at a public offering price of $185.00 per share. The offering closed on November 18, 2021. The Company did not initially receive any proceeds from the sale of shares of its common stock by the forward purchaser or its affiliates. The Company intends to use the net proceeds, if any, received upon the future settlement of the November 2021 Forward Sale Agreements, which it expects to occur no later than November 18, 2022, to fund a portion of the total consideration for the Park Holidays Acquisition, to repay borrowings outstanding under its senior credit facility, to fund possible future acquisitions of properties and/or for working capital and general corporate purposes.

At the Market Offering

On December 17, 2021, the Company entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with certain sales agents and forward sellers pursuant to which it may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of its common stock. The sales agents and forward sellers are entitled to compensation in an agreed amount not to exceed 2.0 percent. Upon entering into the Sales Agreement, the Company simultaneously terminated the At the Market Offering Sales Agreement, dated June 4, 2021 (the "June 2021 Sales Agreement"), which the Company entered into in connection with a prior "at the market" offering program.

During the quarter ended December 31, 2021, the Company entered into forward sale agreements with respect to 1,712,709 shares of common stock under the June 2021 Sales Agreement for $335.1 million prior to the termination of the agreement. Year to date, the Company entered into forward sale agreements with respect to 1,820,109 shares of common stock for $356.5 million under the June 2021 Sales Agreement (the "ATM Forward Sale Agreements" and together with the November 2021 Forward Sale Agreements, the "Outstanding Forward Sale Agreements"). The ATM Forward Sale Agreements were not settled as of December 31, 2021, but the Company expects to settle them no later than September 2022. The Company intends to use the net proceeds, if any, received upon the future settlement of the ATM Forward Sale Agreements, to fund a portion of the total consideration for the Park Holidays Acquisition, to repay borrowings outstanding under its senior credit facility, to fund possible future acquisitions of properties and/or for working capital and general corporate purposes.

2022 Distributions

The Company's Board of Directors has approved setting the 2022 annual distribution rate at $3.52 per common share, an increase of $0.20, or 6.0 percent, over the current $3.32 per common share for 2021. This increase will begin with the first quarter distribution to be paid in April 2022. While the Board of Directors has adopted the new annual distribution policy, the amount of each quarterly distribution on the Company's common stock will be subject to approval by the Board of Directors.

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. Further, 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.

4th Quarter 2021 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 Community results reflect constant currency for comparative purposes. Canadian currency figures in the prior comparative period have been translated at 2021 average exchange rates.

(3)The Same Community MH and RV blended occupancy for 2021 is derived from 119,883 developed sites, of which 117,707 were occupied. The Same Community adjusted MH and RV blended occupancy percentage is derived from 119,002 developed sites, of which 117,707 were occupied. The number of developed sites excludes RV transient sites and nearly 900 recently completed but vacant MH expansion sites.

The Same Community adjusted MH and RV blended occupancy percentage for 2020 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.

(5)Revenue producing site net gains do not include occupied sites acquired during that year.
