Financial Summary & Operating Metrics (in millions, except per share amounts and percentages)

* “Adjusted EBITDA” and “Free cash flow” are non-GAAP measures as defined by the Securities and Exchange Commission (the “SEC”).

DISCUSSION OF RESULTS

Second Quarter 2012 Consolidated Operating Results

Consolidated revenue for the second quarter ended June 30, 2012 was $118.7 million, an increase of 12.4% from $105.6 million for the second quarter of 2011.

Net income for the three months ended June 30, 2012 was $10.1 million, an increase of 34.0% from net income of $7.5 million for the same period of 2011. The year-over-year increase in net income reflects a $1.8 million increase in operating income resulting largely from strong gross profit contribution from our Management and Rental segment in the quarter and favorable non-operating foreign currency fluctuations of $1.6 million. Additionally, during the quarter we recorded a $0.6 million non-cash, pre-tax charge associated with the extinguishment of our term

2

loan in connection with entering into our amended and restated $500 million revolving credit facility.  Second quarter 2012 diluted earnings per share was $0.18 compared to diluted earnings per share of $0.13 for the same period of 2011.

Adjusted EBITDA (defined below) was $37.3 million for the quarter ended June 30, 2012, compared to Adjusted EBITDA of $34.9 million for the same period of 2011.  Adjusted EBITDA for the quarter excludes the impact of non-cash compensation as well as other non-operating income and expenses primarily consisting of non-operating foreign currency exchange net gains of $1.0 million and the aforementioned $0.6 million loss on extinguishment of debt.

Business Segment Results

Membership and Exchange

Membership and Exchange segment revenue for the three months ended June 30, 2012 was $89.7 million, an increase of 2.7% from the comparable period in 2011.

For the second quarter of 2012, transaction revenue was $49.1 million, an increase of 3%, and membership revenue was $32.5 million, consistent with the same period in 2011.

Total active Interval Network members at June 30, 2012 were approximately 1,860,000, an increase of 3.0% from June 30, 2011. Average revenue per member for the second quarter of 2012 was $45.11, largely consistent with the same period in 2011. During the second quarter of 2012, Interval affiliated 16 vacation ownership resorts in domestic and international markets.

Membership and Exchange segment Adjusted EBITDA was $34.7 million in the second quarter, an increase of 1.1% from the second quarter of 2011.

Management and Rental

Management and Rental segment revenue for the three months ended June 30, 2012 was $28.9 million, including $13.6 million of management fee and rental revenue (defined below). Management fee and rental revenue grew by 99.7% on a year-over-year basis. The improvement in management fee and rental revenue was primarily due to the incremental contribution from Vacation Resorts International (VRI) subsequent to our acquisition, higher revenue generated by Trading Places International (TPI) and improvement in RevPAR at Aston.

Aston RevPAR for the quarter ended June 30, 2012 was $117.49 compared to $95.12 for the

3

same period in 2011, driven by a 12.4% and 9.9% improvement in occupancy and average daily rate, respectively, during the quarter.

In the second quarter of 2012, Management and Rental segment Adjusted EBITDA was $2.6 million, compared to $0.6 million in the prior year period.

Capital Resources and Liquidity

As of June 30, 2012, our cash and cash equivalents totaled $121.1 million, compared to $195.5 million as of December 31, 2011. Our total debt outstanding was $285.5 million, net of unamortized bond discount, as of June 30, 2012 compared to $340.1 million as of December 31, 2011. During the second quarter, we entered into an amended and restated $500 million revolving credit facility at an initial interest rate of LIBOR plus 1.75%, replacing an existing $50 million revolving credit facility and term loan with an original principal amount of $150 million, and extinguished the term loan by repaying $51 million of remaining principal outstanding utilizing cash on-hand. There have been no borrowings under the revolving credit facility through June 30, 2012.

Additionally, in July 2012, we issued an irrevocable Notice of Redemption to redeem all of the 9.5% senior notes, which have an outstanding principal balance of $300 million, on September 4, 2012 at 100% of the principal amount plus accrued and unpaid interest to the redemption date.

For the first half of 2012, our capital expenditures totaled $7.3 million, or 3.0% of revenue, net cash provided by operating activities was $50.2 million and free cash flow (defined below) was $42.9 million. Total interest paid during the six months ended June 30, 2012 was $15.0 million.

Dividend

The Board of Directors of Interval Leisure Group has declared a $0.10 per share dividend payable September 20, 2012 to shareholders of record on September 6, 2012.

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 and free

4

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 prepared in accordance with generally accepted accounting principles (GAAP). In addition, Adjusted EBITDA (with certain additional add-backs) is used to calculate compliance with certain financial covenants in ILG’s credit agreement. Management believes that these non-GAAP measures improve the transparency of our disclosures, provide meaningful presentations of our results from our business operations 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 GAAP results to the non-GAAP measures, is available in the financial tables that accompany this press release.
