Marriott Vacations Worldwide Reports First Quarter Financial Results

ORLANDO, Fla. – May 4, 2017 – Marriott Vacations Worldwide Corporation (NYSE: VAC) today reported first quarter financial results and reaffirmed its guidance for the full year 2017. Due to the change in the company’s financial reporting calendar beginning in 2017, the first quarter of 2017 included the period from December 31, 2016 through March 31, 2017 (91 days) compared to the 2016 first quarter, which included the period from January 2, 2016 to March 25, 2016 (84 days). Prior year results have not been restated for the change in the company’s reporting calendar.

First quarter 2017 highlights:

“I couldn’t be more pleased with our start to 2017. In the first quarter, adjusted EBITDA grew over 20 percent to over $62 million, and contract sales, on a year-over-year comparable basis, grew nearly 16 percent,” said Stephen P. Weisz, president and chief executive officer. “Our first quarter was a continuation of the strong performance we delivered in the fourth quarter of 2016 and gives us confidence that we will achieve 2017 full year contract sales growth of 9 to 15 percent, net income of $139 million to $148 million, and adjusted EBITDA of $276 million to $291 million.”

Non-GAAP financial measures, such as adjusted net income, adjusted EBITDA, adjusted fully diluted earnings per share, and adjusted development margin are reconciled and adjustments are shown and described in further detail on pages A-1 through A-11 of the Financial Schedules that follow.

First Quarter 2017 Results

As a result of a change in the company’s financial reporting calendar, financial results for the first quarter 2017 include the impact of seven additional days of operations.

Company Results

First quarter 2017 company net income was $33.7 million, a $9.3 million increase from the first quarter of 2016. These results were driven by $8.6 million of higher resort management and other services revenues net of expenses, $4.5 million of higher development margin, $2.2 million of lower acquisition related transaction costs, $1.7 million of higher financing revenues net of expenses and consumer financing interest expense, and $1.2 million of lower interest expense, partially offset by $2.7 million of higher royalty fees, $2.2 million of higher general and administrative costs, and $0.8 million of lower rental revenues net of expenses.

Total company vacation ownership contract sales were $193.8 million, $40.3 million, or 26.3 percent, higher than the first quarter of 2016. These results were driven by $37.8 million of higher contract sales in the company’s North America segment and $2.5 million of higher contract sales in the company’s Asia Pacific segment. Excluding the estimated impact of the change in the company’s financial reporting calendar, total company vacation ownership contract sales would have increased 15.7 percent.

Development margin was $28.9 million, a $4.5 million increase from the first quarter of 2016. Development margin percentage was 16.8 percent compared to 17.6 percent in the prior year quarter. The increase in development margin reflects $8.3 million from higher contract sales volumes net of expenses, $3.1 million from lower product costs and $1.6 million related mainly to lower usage of plus points for sales incentives, partially offset by $3.3 million related to unfavorable revenue reportability year-over-year, $3.0 million of higher marketing and sales costs primarily from ramping up the company’s new sales distributions, $1.4 million from higher sales reserve activity mainly associated with a 7.6 percentage point increase in financing propensity, and $0.8 million of higher other development and inventory costs. Adjusted development margin percentage, which excludes the impact of revenue reportability year-over-year, was 17.9 percent in the first quarter of 2017 compared to 17.3 percent in the first quarter of 2016.

Rental revenues totaled $85.3 million, a $5.0 million increase from the first quarter of 2016. Rental revenues net of expenses were $14.8 million, a $0.8 million decrease from the first quarter of 2016.

Resort management and other services revenues totaled $74.3 million, a $10.6 million increase from the first quarter of 2016. Resort management and other services revenues, net of expenses, totaled $32.5 million, an $8.6 million, or 36.1 percent, increase from the first quarter of 2016.

Financing revenues totaled $32.1 million, a $2.9 million increase from the first quarter of 2016. Financing revenues, net of expenses and consumer financing interest expense, were $21.0 million, a $1.7 million, or 9.0 percent, increase from the first quarter of 2016.

Marriott Vacations Worldwide Reports First Quarter 2017 Financial Results / 3

Net income was $33.7 million, compared to net income of $24.4 million in the first quarter of 2016, an increase of $9.3 million, or 38.1 percent. Adjusted EBITDA was $62.1 million in the first quarter of 2017, a $10.5 million, or 20.3 percent, increase from $51.6 million in the first quarter of 2016.

Segment Results

North America

North America vacation ownership contract sales were $177.4 million in the first quarter of 2017, an increase of $37.8 million, or 27.1 percent, from the prior year period, reflecting higher sales from existing sales centers driven by the success of our new marketing programs, as well as the continued ramp-up of new sales centers. VPG increased $195, or 5.6 percent, to $3,691 in the first quarter of 2017 from the first quarter of 2016. Total tours in the first quarter of 2017 increased 23.6 percent, reflecting a 23.9 percent increase in first time buyer tours and a 23.5 percent increase in owner tours. Excluding the estimated impact of the change in the company’s financial reporting calendar, vacation ownership contract sales and tours would have increased 16.9 percent and 13.5 percent, respectively.

First quarter 2017 North America segment financial results were $105.7 million, an increase of $16.1 million from the first quarter of 2016. The increase was driven primarily by $8.3 million of higher resort management and other services revenues net of expenses, $4.4 million of higher development margin, $2.8 million of higher financing revenues, and $2.3 million of lower acquisition related transaction costs, partially offset by $1.0 million of higher royalty fees and $0.4 million of lower rental revenues net of expenses.

Development margin was $30.2 million, a $4.4 million increase from the first quarter of 2016. Development margin percentage was 19.2 compared to 20.6 percent in the prior year quarter. The increase in development margin reflects $8.2 million from higher contract sales volumes net of expenses, $2.3 million from lower product costs and $1.6 million related mainly to lower usage of plus points for sales incentives, partially offset by $3.2 million related to unfavorable revenue reportability year-over-year, $3.1 million of higher marketing and sales costs primarily from ramping up the company’s new sales distributions, $0.9 million from higher sales reserve activity mainly associated with a 9.2 percentage point increase in financing propensity, and $0.5 million of higher other development and inventory costs. Adjusted development margin percentage, which excludes the impact of revenue reportability, was 20.7 percent in the first quarter of 2017, slightly above the first quarter of 2016.

Asia Pacific

Total vacation ownership contract sales in the segment were $11.9 million, an increase of $2.5 million, or 26.7 percent, from the first quarter of 2016, due primarily to the opening of the new sales location in Surfers Paradise, Australia in the second quarter of 2016. Segment financial results were $1.1 million, relatively flat to the first quarter of 2016. Excluding the estimated impact of the change in the company’s financial reporting calendar, vacation ownership contract sales would have increased 16.0 percent.

Europe

First quarter 2017 contract sales were $4.4 million and segment financial results were $0.7 million, both relatively flat to the first quarter of 2016.

The company had $692.1 million in gross debt outstanding at the end of the first quarter, a decrease of $54.4 million from year-end 2016, consisting primarily of $684.0 million in gross non-recourse securitized notes.

NON-GAAP FINANCIAL MEASURES

In our press release and schedules, and on the related conference call, we report certain financial measures that are not prescribed by United States generally accepted accounting principles (“GAAP”). We discuss our reasons for reporting these non-GAAP financial measures below, and the financial schedules reconcile the most directly comparable GAAP financial measure to each non-GAAP financial measure that we report (identified by a double asterisk (“**”) on the preceding pages). Although we evaluate and present these non-GAAP financial measures for the reasons described below, please be aware that these non-GAAP financial measures have limitations and should not be considered in isolation or as a substitute for revenues, net income, earnings per share or any other comparable operating measure prescribed by GAAP. In addition, these non-GAAP financial measures may be calculated and / or presented differently than measures with the same or similar names that are reported by other companies, and as a result, the non-GAAP financial measures we report may not be comparable to those reported by others.

Adjusted Net Income. We evaluate non-GAAP financial measures, including Adjusted Net Income, Adjusted EBITDA, and Adjusted Development Margin, that exclude certain items in the quarters ended March 31, 2017 and March 25, 2016 because these non-GAAP financial measures allow for period-over-period comparisons of our on-going core operations before the impact of these items. These non-GAAP financial measures also facilitate our comparison of results from our on-going core operations before these items with results from other vacation ownership companies.

Certain items—Quarter Ended March 31, 2017. In our Statement of Income for the quarter ended March 31, 2017, we recorded $0.5 million of net pre-tax items, which included $0.4 million of acquisition costs and $0.1 million of losses and other expense not associated with our on-going core operations.

Certain items—Quarter Ended March 25, 2016. In our Statement of Income for the quarter ended March 25, 2016, we recorded $2.1 million of net pre-tax items, which included $2.6 million of acquisition costs, $0.2 million of income (or $0.5 million of EBITDA) from the operations of the property we acquired in Australia in 2015 that we sold in the second quarter of 2016, and a $0.3 million reversal of litigation settlement expense.

Adjusted Development Margin (Adjusted Sale of Vacation Ownership Products Net of Expenses). We evaluate Adjusted Development Margin (Adjusted Sale of Vacation Ownership Products Net of Expenses) as an indicator of operating performance. Adjusted Development Margin adjusts Sale of vacation ownership products revenues for the impact of revenue reportability, includes corresponding adjustments to Cost of vacation ownership products expense and Marketing and sales expense associated with the change in revenues from the Sale of vacation ownership products, and includes adjustments for certain items as itemized in the discussion of Adjusted Net Income above. We evaluate Adjusted Development Margin because it allows for period-over-period comparisons of our on-going core operations before the impact of revenue reportability and certain items to our Development Margin.

NON-GAAP FINANCIAL MEASURES

Earnings Before Interest Expense, Taxes, Depreciation and Amortization (“EBITDA”) and Adjusted EBITDA. EBITDA is defined as earnings, or net income, before interest expense (excluding consumer financing interest expense), provision for income taxes, depreciation and amortization. For purposes of our EBITDA and Adjusted EBITDA calculations, we do not adjust for consumer financing interest expense because the associated debt is secured by vacation ownership notes receivable that have been sold to bankruptcy remote special purpose entities and is generally non-recourse to us. Further, we consider consumer financing interest expense to be an operating expense of our business. We consider EBITDA and Adjusted EBITDA to be indicators of operating performance, which we use to measure our ability to service debt, fund capital expenditures and expand our business. We also use EBITDA and Adjusted EBITDA, as do analysts, lenders, investors and others, because these measures exclude certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be dependent on a company’s capital structure, debt levels and credit ratings. Accordingly, the impact of interest expense on earnings can vary significantly among companies. The tax positions of companies can also vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the jurisdictions in which they operate. As a result, effective tax rates and provision for income taxes can vary considerably among companies. EBITDA and Adjusted EBITDA also exclude depreciation and amortization because companies utilize productive assets of different ages and use different methods of both acquiring and depreciating productive assets. These differences can result in considerable variability in the relative costs of productive assets and the depreciation and amortization expense among companies. Adjusted EBITDA reflects additional adjustments for certain items, as itemized in the discussion of Adjusted Net Income above, including, beginning with the first quarter of 2016, the exclusion of non-cash share-based compensation expense to address considerable variability among companies in recording compensation expense because companies use share-based payment awards differently, both in the type and quantity of awards granted. Prior period presentation has been recast for consistency. We evaluate Adjusted EBITDA as an indicator of operating performance because it allows for period-over-period comparisons of our on-going core operations before the impact of the excluded items. Together, EBITDA and Adjusted EBITDA facilitate our comparison of results from our on-going core operations before the impact of these items with results from other vacation ownership companies.

Free Cash Flow and Adjusted Free Cash Flow. We evaluate Free Cash Flow and Adjusted Free Cash Flow as liquidity measures that provide useful information to management and investors about the amount of cash provided by operating activities after capital expenditures for property and equipment, changes in restricted cash, and the borrowing and repayment activity related to our securitizations, which cash can be used for strategic opportunities, including acquisitions and strengthening the balance sheet. Adjusted Free Cash Flow, which reflects additional adjustments to Free Cash Flow for the impact of organizational and separation related, litigation, and other cash charges, allows for period-over-period comparisons of the cash generated by our business before the impact of these items. Analysis of Free Cash Flow and Adjusted Free Cash Flow also facilitates management’s comparison of our results with our competitors’ results.
