Hurricane Impact

In September 2017, Hurricanes Irma and Maria affected several Vistana and HVO resorts and sales centers, as well as nearly 300 properties within the Interval Network or managed by VRI or Aqua-Aston Hospitality. At June 30, 2018 our Westin St. John Resort Villas in the U.S. Virgin Islands and Hyatt Residence Club Dorado, Hacienda del Mar, in Puerto Rico were closed and expected to reopen early in 2019. Approximately 35 Interval Network properties on the hardest-hit islands remained closed at quarter end.

The table below summarizes our results for the second quarter of 2018 and provides the estimated impact of the hurricanes in these periods:

Second quarter consolidated operating results

Consolidated revenue was $461 million, and excluding the estimated hurricane impact, it would have been $479 million, up 9% over the prior year driven by strong performance in our vacation ownership segment.

Net income attributable to common stockholders was $27 million. Excluding the estimated impact of the hurricanes it would have been $31 million, up 19% compared to the prior year. Diluted earnings per share (EPS) was $0.21, compared to $0.20 in the prior year.

Adjusted net income was $39 million, higher by 26%. Excluding the estimated impact from the hurricanes, it would have been $42 million, up 35% compared to the prior year. Adjusted diluted EPS was $0.31. Excluding the impact from the hurricane it would have been $0.34, higher by 36%.

Adjusted EBITDA increased 13% to $90 million. Excluding the impact from the hurricane, it would have been $95 million, an increase of 19% compared to 2017.

Business segment results

Vacation Ownership

Excluding cost reimbursements, Vacation Ownership segment revenue increased $37 million, to $263 million principally as a result of the following:

·                  $28 million increase in management fee and other revenue predominantly attributable to revenue from the consolidation of our HOAs starting in the fourth quarter of 2017. This increase is largely offset by a corresponding decrease in cost reimbursement revenue.

·                  $5 million increase in resort operations revenue primarily driven by higher available and occupied room nights and average daily rate resulting from the increase in the number of units which came on-line beginning in the second quarter of 2017.

·                  $3 million increase in sales of vacation ownership products principally attributable to higher consolidated contract sales

Vacation Ownership segment operating income more than doubled to $17 million and adjusted EBITDA was higher by $10 million to $41 million. Excluding the impact of the hurricanes, adjusted EBITDA would have increased $14 million to $45 million, 45% higher than 2017.

Exchange and Rental

Exchange and Rental segment revenue was $153 million dollars, relatively consistent with 2017. Excluding cost reimbursements, segment revenue was up 2% to $133 million dollars related to stronger club rental revenue resulting from the above-mentioned increase in available and occupied room nights and average daily rate.

Total Interval Network active members at quarter-end were 1.8 million, consistent with 2017, and average revenue per member was $48.14, up 2%.

Operating income for the segment was $35 million compared to $37 million in 2017 reflecting the adverse impact from the hurricanes and higher professional fees largely due to costs associated with our expected transaction with Marriott Vacations Worldwide. Adjusted EBITDA for the segment was $49 million, consistent with 2017. Excluding the estimated hurricane impact, adjusted EBITDA would have increased by 2%.

Capital Resources and Liquidity

As of June 30, 2018, ILG’s cash and cash equivalents totaled $143 million, compared to $122 million on December 31, 2017, and we had $242 million of eligible unsecuritized receivables.

The principal amount outstanding of long term corporate debt as of June 30, 2018 was $555 million consisting of $350 million 5 5/8% Senior Notes and $205 million drawn under our revolving credit facility.

ILG had $382 million available on its revolving credit facility, net of outstanding letters of credit as of June 30, 2018.

3

Net cash and restricted cash provided by operating activities in the first six months of 2018 was $184 million compared to $82 million. The $102 million increase was principally due to lower inventory spend of $81 million due to development activities at the Westin Nanea Ocean Villas in the prior year period, to higher net cash receipts partly attributable to property insurance proceeds of $42 million related primarily to the damage caused by the 2017 hurricanes on our Westin St. John resort and to lower taxes paid of $4 million. The increases were partly offset by $4 million of higher interest paid (net amounts capitalized).

Net cash used in investing activities was $18 million primarily related to capex associated with resort operations and sales and marketing locations, as well as IT initiatives. Capex in the quarter includes an offsetting $3 million of insurance proceeds for hurricane property damage.

Net cash and restricted cash used in financing activities was $153 million, reflecting $86 million repayments on securitized debt, net payments of $15 million on our revolving credit facility, dividend payments of $43 million, and $9 million withholding tax on the vesting of restricted stock units and shares.

Free cash flow for the six months ended June 30, 2018 was $95 million, compared to $23 million in 2017.  The change is primarily a result of the increase in net cash provided by operating activities, and lower capital expenditures, partially offset by higher net securitization activities, including higher repayments on securitizations.

Dividends

During the first six months of 2018, ILG paid $43 million, or $0.35 cents per share in dividends.

Combination with Marriott Vacations

On April 30, 2018, ILG announced it had entered into an agreement whereby Marriott Vacations Worldwide, Inc. (Marriott Vacations) will acquire ILG for a combination of cash and stock consideration which values the company at approximately $5.1 billion, based on Marriott Vacation’s closing price on April 27, 2018.

ILG shareholders will receive $14.75 per share in cash and the rest in newly issued shares of Marriott Vacations. The combination will result in ILG shareholders owning at closing approximately 43% of the company on a fully-diluted basis, based on a fixed exchange ratio.  Two ILG directors will be appointed to the board of the combined company.

The transaction, which is subject to shareholder approval and other customary closing conditions, is expected to close at the end of August. More information on the transaction can be found on the ILG website, ww.ilg.com.

PRESENTATION OF FINANCIAL INFORMATION

ILG management believes that the presentation of non-generally accepted accounting principles (non-GAAP) financial measures, including, among others, EBITDA, adjusted EBITDA, adjusted net income, adjusted basic and diluted EPS, and free cash flow, serves to enhance the understanding of ILG’s performance. These non-GAAP financial measures should be considered in addition to and not as substitutes for, or superior to, measures of financial performance and liquidity prepared in accordance with generally accepted accounting principles (GAAP). In addition, adjusted EBITDA (with certain different adjustments) is used to calculate compliance with certain financial covenants in ILG’s credit agreement and indenture. Management believes that these non-GAAP measures improve the transparency of our disclosures, provide meaningful presentations of our results from our business operations and liquidity excluding the impact of certain items not related to our core business operations and improve the period to period comparability of results from business operations. These measures may also be useful in comparing our results to those of other companies; however, our calculations may differ from the calculations of these measures used by other companies. More information about the non-GAAP financial measures, including reconciliations of historical GAAP results to the non-GAAP measures, is available in the financial tables that accompany this press release.
