NEWS RELEASE

April 23, 2018

Sun Communities, Inc. Reports 2018First Quarter Results

Southfield, Michigan, April 23, 2018– Sun Communities, Inc. (NYSE: SUI) (the “Company”), a real estate investment trust (“REIT”) that owns and operates, or has an interest in, manufactured housing (“MH”) and recreational vehicle (“RV”) communities, today reported its first quarter results for 2018.

Financial Results for the Three Months Ended March 31, 2018

For the three months ended March 31, 2018, total revenues increased $23.5 million, or 10.0 percent, to $257.9 million compared to $234.4 million for the same period in 2017. Net income attributable to common stockholders was $30.0 million, or $0.38 per diluted common share, for the three months ended March 31, 2018, as compared to net income attributable to common stockholders of $21.1 million, or $0.29 net income per diluted common share, for the same period in 2017.

Non-GAAP Financial Measures and Portfolio Performance

• Core Funds from Operations (“Core FFO”)⁽¹⁾for the three months ended March 31, 2018, was $1.14 per diluted share and OP unit (“Share”) as compared to $1.10 in the prior year, an increase of 3.6 percent.

• Same Community⁽²⁾ Net Operating Income (“NOI”)⁽¹⁾ increased by 5.3 percent for the three months ended March 31, 2018, as compared to the same period in 2017.

• Recurring EBITDA⁽¹⁾increased by 8.0 percent for the three months ended March 31, 2018, as compared to the same period in 2017.

• Home sales volumes increased 1.3 percent for the three months ended March 31, 2018, as compared to the same period in 2017. New home sales volumes increased 39.5 percent to 106 for the three months ended March 31, 2018, as compared to 76 in the same period in 2017.

• Revenue producing sites increased by 616 sites for the three months ended March 31, 2018, as compared to a 687 site increase in the same period in 2017.

“Our positive results in the first quarter of 2018 were driven by solid occupancy gains, strong home sales and rentals, and a robust winter RV season,” said Gary A. Shiffman, Chairman and Chief Executive Officer. “Our continued revenue growth underscores the ongoing demand for Sun’s communities. Furthermore, we delivered 246 new expansion sites in the quarter, which should contribute to our growth as they become revenue producing sites over time. Finally, our well positioned balance sheet supports an active pipeline of acquisition opportunities as we continue to pursue single asset and small portfolio investments. These combined elements are essential to Sun’s ability to generate superior total shareholder return over time.”

OPERATING HIGHLIGHTS

Community Occupancy

Total portfolio occupancy was 95.8 percent at March 31, 2018, compared to 95.9 percent at March 31, 2017. The slight decline in occupancy was primarily attributable to recently completed but vacant MH expansion sites.

During the three months ended March 31, 2018, revenue producing sites increased by 616 sites, as compared to a 687 revenue producing site increase during the first quarter of 2017.

Same Community⁽²⁾ Results

For the 336 stabilized communities owned and operated by the Company since January 1, 2017, NOI⁽¹⁾ for the three months ended March 31, 2018 increased 5.3 percent over the same period in 2017, as a result of a 5.7 percent increase in revenues and a 6.6 percent increase in operating expenses.  Operating expenses during the quarter increased primarily due to higher than expected insurance and utility expenses. Same Community occupancy⁽³⁾ increased to 97.6 percent at March 31, 2018 from 95.4 percent at March 31, 2017.

Home Sales

During the three months ended March 31, 2018, the Company sold 837 homes as compared to 826 homes sold during the same period in 2017, a 1.3 percent increase.

Rental homes sales, which are included in total home sales, were 234 and 240 for the three months ended March 31, 2018 and 2017, respectively.

BALANCE SHEET AND CAPITAL MARKETS ACTIVITY

Debt Transactions

During the quarter ended March 31, 2018, the Company repaid four collateralized term loans totaling $24.4 million with a weighted average interest rate of 6.36 percent, releasing three encumbered communities. The loans were due to mature in March 2019.

As of March 31, 2018, the Company had $3.1 billion of debt outstanding. The weighted average interest rate was 4.45 percent and the weighted average maturity was 8.5 years. The Company had $15.2 million of unrestricted cash on hand. At period-end the Company’s net debt to trailing twelve month Recurring EBITDA⁽¹⁾ ratio was 6.2 times.

Equity Transactions

After quarter end, the Company issued 220,000 shares of common stock through its At-the-Market equity sales program at a weighted average price of $91.31 per share. Net proceeds from the sales were $19.8 million.

2018 Distributions

As previously announced, the Company increased its annual distribution by 6.0 percent to $2.84 per common share from $2.68 per common share. The increase began with the distribution declared in March 2018 that was paid after quarter end.

GUIDANCE 2018

The Company affirms full year 2018 net income per diluted share to be in the range of $1.26 to $1.42 and Core FFO⁽¹⁾per Share to be in the range of $4.48 to $4.58. The Company anticipates second quarter 2018 net income per diluted share to be in the range of $0.24 to $0.28 and Core FFO⁽¹⁾per Share to be in the range of $1.03 to $1.06.

The Company is adjusting its 2018 Same Community NOI⁽¹⁾growth guidance for the year by 25 basis points to 6.75 percent to 7.25 percent from the prior range of 7.0 percent to 7.5 percent. Guidance does not include prospective acquisitions or capital markets activity.

Core FFO⁽¹⁾ per Share estimates assume certain gain and loss items that management considers unrelated to the operational and financial performance of our core business will be adjusted from FFO⁽¹⁾. The estimates and assumptions presented above represent a range of possible outcomes and may differ materially from actual results. The estimates and assumptions are forward looking based on the Company’s current assessment of economic and market conditions, as well as other risks outlined below under the caption “Forward-Looking Statements.”

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, and after adjustments for unconsolidated 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

1st Quarter 2018 Supplemental Information     21          Sun Communities, Inc.

property and of investments in unconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, and adjustments to reflect the entity’s share of EBITDAre of unconsolidated 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. 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 2018 actual exchange rates.

(3) The Same Community occupancy percentage for 2018 is derived from 102,732 developed sites, of which 100,219 where occupied. The number of developed sites excludes RV transient sites and approximately 1,800 recently completed but vacant MH expansion sites. The Same Community occupancy percentage for 2017 has been adjusted to reflect incremental period-over-period growth from filled expansion sites and the conversion of transient RV sites to annual RV sites.

(4) This is a transferred asset transaction which has been classified as collateralized receivables and the cash received from this transaction has been classified as a secured borrowing. The interest income and interest expense accrue at the same rate and amount.

(5) In January 2018, new accounting guidance became effective, which clarified the definition of a business with the objective of assisting entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. Under previous guidance, substantially all of the Company’s property acquisitions were accounted for as business combinations with identifiable assets and liabilities measured at fair value, and acquisition related costs expensed as incurred and reported as Transaction costs. Under the new guidance, the Company expects that substantially all of its future property acquisitions will be accounted for as asset acquisitions. The purchase price of these properties will be allocated on a relative fair value basis and direct acquisition related costs will be capitalized as part of the purchase price. Acquisitions costs that do not meet the criteria for capitalization will be expensed as incurred and reported as General and administrative costs.

(6) Other income / (expense), net for the three months ended March 31, 2018 was comprised primarily of a foreign currency translation loss of $2.5 million. For the three months ended March 31, 2017, the balance was comprised primarily of a foreign currency translation gain of $0.8 million.

(7) These 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.

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

(9) Core FFO⁽¹⁾ for the three months ended March 31, 2018, includes an adjustment of $0.3 million for estimated loss of earnings in excess of the applicable business interruption deductible in relation to our Florida Keys communities that require redevelopment due to damages sustained from Hurricane Irma in September 2017, as previously announced.

(10) The renter’s monthly payment includes the site rent and an amount attributable to the home lease. Site rent is reflected in Real Property NOI. For purposes of management analysis, site rent is included in Rental Program revenue to evaluate the incremental revenue gains associated with implementation of the Rental Program, and to assess the overall growth and performance of the Rental Program and financial impact on the Company’s operations.

(11) Lines of credit includes the Company’s MH floor plan facility. The effective interest rate on the MH floor plan facility was 7.0 percent for all periods presented. However, the Company pays no interest if the floor plan balance is repaid within 60 days.

(12) Same Community results net $7.9 million and $7.6 million of utility revenue against the related utility expense in property operating and maintenance expense for the three months ended March 31, 2018 and 2017, respectively.

1st Quarter 2018 Supplemental Information     22          Sun Communities, Inc.

(13) Same Community property operating and maintenance expense for the three months ended March 31, 2017, excludes $0.8 million 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.

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

(15) Calculated using actual results without rounding.

(16) Acquisitions and other is comprised of nine properties acquired in 2017, three Florida Keys properties that require redevelopment as a result of damage sustained from Hurricane Irma in 2017, one property undergoing redevelopment, and one property that we have an interest in but do not operate.

(17) Includes MH and annual RV sites, and excludes transient RV sites, as applicable. Total sites for development were comprised of approximately 81.6 percent for expansion, 12.6 percent for greenfield development and 5.8 percent for redevelopment.

(18) At March 31, 2018, total portfolio MH occupancy was 94.7 percent (including the impact of approximately 1,800 recently completed but vacant expansion sites) and annual RV occupancy was 100.0 percent.

(19) Recurring capital expenditures are necessary to maintain asset quality, including purchasing and replacing assets used to operate the community. These capital expenditures 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. The minimum capitalized amount is five hundred dollars.

(20) Lot modification capital expenditures 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.

(21) Capital expenditures related to acquisitions represent the purchase price of existing operating communities and land parcels to develop expansions or new communities. These costs for the three months ended March 31, 2018 include $6.8 million of capital improvements identified during due diligence that are necessary to bring a community to the Company’s standards. 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.

(22) Expansion and development expenditures consist primarily of construction costs and costs necessary to complete home site improvements.

(23) Capital costs related to revenue generating activities consist primarily of garages, sheds, sub-metering of water, sewer and electricity. Revenue generating attractions at our RV resorts are also included here and, occasionally, a special capital project requested by residents and accompanied by an extra rental increase will be classified as revenue producing.

(24) Net leased sites do not include occupied sites acquired during that year.

Certain financial information has been revised to reflect reclassifications in prior periods to conform to current period presentation.
