On June 14, 2021, the Company received investment grade ratings of BBB and Baa3 with a stable outlook from S&P Global and Moody's, respectively.

The net proceeds from the offering were $592.4 million, after deducting underwriters' discount and estimated offering expenses.

Credit Agreement

On June 14, 2021, SCOLP, as borrower, and the Company, as guarantor, entered into a new credit agreement with certain lenders. The new credit agreement combines and replaces SCOLP's $750.0 million credit facility which was scheduled to mature May 21, 2023, and the $1.8 billion credit facility of the Company's marina subsidiary, Safe Harbor Marinas, LLC (the "Safe Harbor Facility") which was scheduled to mature on October 11, 2024. The Safe Harbor Facility was terminated in connection with the execution of the new credit agreement and all amounts due and outstanding were repaid on or prior to the date of the New Credit Agreement. The Company recognized a loss on extinguishment of debt in its Consolidated Statement of Operations related to the termination of these prior credit facilities of $0.2 million and $7.9 million, respectively.

Pursuant to the New Credit Agreement, SCOLP may borrow up to $2.0 billion under a revolving loan (the "New Credit Facility") to fund the business of SCOLP and all its subsidiaries. The New Credit Facility has a four-year term ending June 14, 2025. Subject to the satisfaction of certain conditions, the term may be extended for two additional six-month periods, and additional borrowings not to exceed $1.0 billion is permitted. However, the maturity date with respect to $500.0 million of available borrowing under the New Credit Facility is October 11, 2024, which may not be extended. The New Credit Facility bears interest at a floating rate based on the Adjusted Eurocurrency Rate or Australian Bank Bill Swap Bid Rate (BBSY), plus a margin which can range from 0.725 percent to 1.400 percent. As of June 30, 2021, the margin based on our credit ratings was 0.850 percent on the New Credit Facility. The Company had $190.3 million of borrowings on the New Credit Facility as of June 30, 2021.

In May and June 2021, the Company completed the physical settlement of the remaining 4,050,000 shares offered under the forward sale agreement pursuant to the Company's March 2021 equity offering of 8,050,000 shares. Net proceeds of $539.7 million after deducting expenses related to the offering, were used to acquire assets and pay down the Safe Harbor 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. 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.

2nd Quarter 2021 Supplemental Information 24 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 MH and RV blended occupancy is derived from 119,933 developed sites, of which 117,536 were occupied. The 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. The adjusted MH and RV blended occupancy percentage for 2021 is derived from 118,907 developed sites, of which 117,536 were occupied. The number of developed sites excludes RV transient sites and over 1,000 recently completed but vacant MH expansion sites.

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

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

(6)Other expense, net was as follows (in thousands):

(7)Other acquisition related costs represent the 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. These costs also include nonrecurring integration expenses associated with a new acquisition.

(8)Line of credit and other debt includes borrowings under the Company's $2.0 billion New Credit Facility and a $12.0 million MH floor plan facility. The effective interest rate on the MH floor plan facility was 7.0 percent for the quarters ended June 30 and March 31, 2021, and 6.0 percent for the quarters ended December 31, September 30 and June 30, 2020. However, the Company pays no interest if the floor plan balance is repaid within 60 days.

(9)Same Community results net $16.8 million and $14.3 million of certain utility revenue against the related utility expense in property operating and maintenance expense for the three months ended June 30, 2021 and 2020, respectively. Same Community results net $33.2 million and $29.1 million of utility revenue against the related utility expense in property operating and maintenance expense for the six months ended June 30, 2021 and 2020, respectively.

(10)Same Community supplies and repair expense excludes $0.5 million and $0.9 million for the three and six months ended June 30, 2020, respectively, of expenses incurred for recently acquired properties to bring the 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.

(11)Monthly base rent per site pertains to annual RV sites and excludes transient RV sites.

(12)Calculated using actual results without rounding.

(13)MH and RV acquisitions and other is comprised of eight properties acquired and five properties that the Company has an interest in, but does not operate in 2021, 23 properties acquired in 2020, two Florida Keys properties that require redevelopment as a result of damage sustained from Hurricane Irma in 2017, seven recently opened ground-up developments, one property undergoing redevelopment, four properties previously classified as held for sale and other miscellaneous transactions and activity.

2nd Quarter 2021 Supplemental Information 25 Sun Communities, Inc.

(14)Includes MH and annual RV sites, and excludes transient RV sites, as applicable.

(15)As of June 30, 2021, total portfolio MH occupancy was 96.7 percent inclusive of the impact of nearly 1,200 recently constructed but vacant MH expansion sites, and annual RV occupancy was 100.0 percent.

(16)Total sites for development were comprised of approximately 77.9 percent for expansion, 19.8 percent for greenfield development and 2.3 percent for redevelopment.

(17)Property recurring capital expenditures are necessary to maintain asset quality, including purchasing and replacing assets used to operate the communities, resorts and marinas. Recurring capital expenditures at our MH and RV properties include items such as: major road, driveway, pool improvements; clubhouse renovations; adding or replacing street lights; playground equipment; signage; maintenance facilities; manager housing and property vehicles. Recurring capital expenditures at our marinas include items such as: dredging, dock repairs and improvements, and equipment maintenance and upgrades. The minimum capitalized amount is five hundred dollars.

(18)Lot modification capital expenditures are MH expenditures necessary to improve the asset quality of the community. These costs are incurred when an existing older home moves out, and the site is prepared for a new home, more often than not, a multi-sectional home. These activities, which are mandated by strict manufacturer's installation requirements and state building code, include items such as new foundations, driveways, and utility upgrades.

(19)Capital expenditures related to acquisitions represent the purchase price of existing operating properties (including marinas) and land parcels to develop expansions or new properties. These costs for the six months ended June 30, 2021 include $70.7 million of capital improvements identified during due diligence that are necessary to bring the communities, resorts and marinas to the Company's operating standards. For the years ended December 31, 2020 and 2019, these costs were $40.6 million and $50.7 million, respectively. These include items such as: upgrading clubhouses; landscaping; new street light systems; new mail delivery systems; pool renovation including larger decks, heaters, and furniture; new maintenance facilities; and new signage including main signs and internal road signs. These are considered acquisition costs and although identified during due diligence, often require 24 to 36 months after closing to complete.

(20)Expansion and development expenditures consist primarily of construction costs and costs necessary to complete home and RV site improvements, such as driveways, sidewalks and landscaping at our MH communities and RV resorts.

(21)Growth projects consist of revenue generating or expense reducing activities at MH communities, RV resorts and marinas. This includes, but is 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.
