Consolidated Financial Highlights

Consistent execution of brand-specific strategic initiatives drove RBI outperformance in the second quarter. TH trailing twelve month NRG of 230 along with comparable sales growth of 5.5% drove TH system-wide sales growth of 8.4%. Strength in Dark Roast coffee and the CREAMY CHOCOLATE CHILL™ beverage as well as growth in the lunch daypart contributed to TH outperformance. At BK, trailing twelve month NRG of 720 in conjunction with second quarter comparable sales growth of 6.7% led to BK system-wide sales growth of 11.6%. BK comparable sales growth was largely driven by innovative product launches including the A.1.^® Hearty Mozzarella Bacon Cheeseburger, Extra Long Pulled Pork Sandwich and Chicken Fries.

TH Segment Results ⁽²⁾

Comparable sales growth and NRG for the trailing twelve month period contributed to TH system-wide sales growth of 8.4% in the second quarter. TH comparable sales grew 5.5%, with comparable sales growth for TH Canada and TH U.S. markets at 5.4% and 7.0%, respectively.

TH Total Revenues declined 4.3% versus the prior year pro forma amount to $763.2 million, primarily as a result of FX headwinds. Excluding the impact of FX movements, TH Total Revenues increased 7.9% compared to prior year pro forma results. Year-over-year, TH Adjusted EBITDA grew 22.8% on an organic basis (excluding the impact of FX movements) as a result of top-line growth, operating leverage and cost discipline.

BK Segment Results

Comparable sales growth and acceleration of net restaurant openings at BK helped drive system-wide sales growth of 11.6%. BK achieved comparable sales growth of 6.7% with positive same-store sales in all markets. U.S. and Canada and Latin America and the Caribbean notably outperformed with comparable sales growth of 7.9% and 8.5%, respectively. BK top-line growth was largely attributable to comparable sales growth and the addition of 720 net new restaurants for the trailing twelve month period.

Cash and Liquidity

As of June 30, 2015 total debt was $8.9 billion and net debt was $8.2 billion. Our cash balance of $0.7 billion was down $0.3 billion versus the prior quarter, primarily as a result of our debt refinancing in May, in which we paid down $1.55 billion of our Term Loan with $0.3 billion of cash and the proceeds from the $1.25 billion issuance of 4.625% First Lien Senior Notes due January 15, 2022.

Key Business Metrics

We evaluate our restaurants and assess our business based on the following operating metrics.

System-wide sales growth refers to the change in sales at all company-owned and franchise restaurants in one period from the same period in the prior year. Comparable sales growth refers to the change in restaurant sales in one period from the same prior year period for restaurants that have been open for thirteen months or longer. Company-owned restaurants refranchised during a quarterly period are included with franchise restaurants for the purpose of calculating comparable sales growth for the quarter. Comparable sales and sales growth are measured on a constant currency basis, which means that results exclude the effect of foreign currency translation and are calculated by translating prior year results at current year monthly average exchange rates. We analyze key operating metrics on a constant currency basis as this helps identify underlying business trends, without distortion from the effects of currency movements (“FX Impact”).

System-wide sales represent sales at all Company restaurants and franchise restaurants. We do not record franchise sales as revenues; however, our franchise revenues include royalties based on a percentage of franchise sales.

Non-GAAP Financial Measures

(Unaudited)

Below, we define the non-GAAP financial measures, provide a reconciliation of each non-GAAP financial measure to the most directly comparable financial measure calculated in accordance with GAAP, and discuss the reasons that we believe this information is useful to management and may be useful to investors. These measures may differ from similarly captioned measures of other companies in our industry.

Non-GAAP Measures:

To supplement its condensed consolidated financial statements presented on a U.S. Generally Accepted Accounting Principles (“GAAP”) basis, RBI reports the following non-GAAP financial measures: EBITDA, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, Organic revenue growth and Organic Adjusted EBITDA growth.

EBITDA is defined as earnings (net income or loss) before interest, (gain) loss on early extinguishment of debt, taxes, and depreciation and amortization and is used by management to measure operating performance of the business.

Adjusted EBITDA is defined as EBITDA excluding the impact of share-based compensation and non-cash incentive compensation expense, (income) loss from equity method investments, net of cash distributions received from equity method investments, other operating (income) expenses, net, and all other specifically identified costs associated with non-recurring projects, including acquisition accounting impact on cost of sales and Tim Hortons transaction and restructuring costs. Adjusted EBITDA is used by management to measure operating performance of the business, excluding specifically identified items that management believes do not directly reflect our core operations, and represents our measure of segment income.

Adjusted Net Income is defined as net income excluding the impact of those same items excluded from Adjusted EBITDA and also excluding franchise agreement amortization, amortization of deferred financing costs and original issue discount, interest expense and loss (gain) on extinguished debt. Adjusted Diluted EPS is calculated by dividing Adjusted Net Income by the number of diluted shares of RBI during the reporting period. Adjusted Net Income and Adjusted Diluted EPS are used by management to evaluate the core operating performance of the business.

Revenue growth and Adjusted EBTIDA growth, on an organic basis, are non-GAAP measures that exclude FX Impact. Management believes that organic growth is an important metric for measuring the core operating performance of the business as it excludes the impact of foreign currency exchange rates. Organic growth is calculated by dividing this period’s financial results by the average monthly exchange rates for the prior period.
