“Our business performed well in the second quarter with strong top-line results in both Canada and the U.S. We overcame softness early in the quarter in Canada and delivered strong same-store sales growth in both Canada and the U.S. We continue to focus on executing our strategic plan, taking advantage of market opportunities and our strengths, to grow our business and respond to our guests’ needs,” said Paul House, executive chairman, and president and CEO.

Consolidated Results

All percentage increases and decreases represent year-over-year changes for the second quarter of 2011 compared to the second quarter of 2010, unless otherwise noted.

Systemwide sales⁽⁴⁾ grew 7.2% on a constant currency basis in the second quarter. Total revenues grew 9.8% to $702.8 million compared to $639.9 million last year. Our total revenue growth was driven by distribution sales that outpaced systemwide sales growth, due to higher commodity pricing primarily related to coffee. Rents and royalties benefited from same-store sales growth and new restaurant growth. Franchise fees were slightly lower, down 1.7% during the quarter.

Costs and expenses were higher year-over-year primarily due to two factors. Increased cost of sales reflected the impacts of the bakery disposition and the significantly higher underlying cost of coffee. General and administrative expenses were negatively impacted by the $6.3 million charge, including advisory and other related costs and expenses pertaining to the separation agreement with the former president and CEO.

Second quarter operating income declined 4.4% to $143.2 million compared to $149.9 million last year, due primarily to the lost contribution from Maidstone Bakeries in the comparable period results and the impact of the separation agreement previously noted. Systemwide sales growth benefited higher rents and royalties and distribution income in both Canada and the U.S. Absent costs related to the separation agreement and the net $12.4 million negative year-over-year impact of the sale of Maidstone Bakeries, operating income would have increased 8.9%.

Net income attributable to Tim Hortons increased by 1.5% to $95.5 million in the second quarter, compared to $94.1 million last year, benefiting from a slightly lower effective tax rate during the quarter.

In the second quarter EPS rose 8.3% to $0.58, compared to $0.54 last year. Our EPS benefited from higher share repurchases related to net proceeds used from our Maidstone Bakeries joint venture sale. We spent approximately $206 million to repurchase 4.6 million shares in the second quarter, contributing to the cumulative reduction of our average diluted outstanding shares by 6.2% from the comparable period. The separation agreement relating to the former president and CEO negatively impacted EPS by $0.03. Absent this charge, EPS would have increased by 13.5%.

Segmented Performance Commentary

Canada

Same-store sales in the Canadian segment grew by 3.8% as a result of average cheque growth, which benefited from favourable pricing and product mix, resulting in two-year cumulative same-store sales growth of more than 10%. Successful menu initiatives such as Real Fruit Smoothies, which helped grow our cold beverage category, contributed to product mix changes in the quarter. Same-store sales were softer in April reflecting the partial shift of the Easter holiday, but strengthened sequentially as the quarter progressed.

2

During the second quarter we opened 24 restaurants in Canada, the majority of which were standard restaurants.

Canadian segment operating income in the second quarter grew 3.8% to $156.4 million compared to $150.7 million last year. Higher systemwide sales growth and higher distribution income were partially offset by the lost earnings contribution from Maidstone Bakeries. Higher distribution income was due in part to the temporary positive impact from the timing of coffee pricing and underlying costs in our supply chain, which we expect will reverse in the second half of 2011 and have a neutral effect on the year.

United States

Our U.S. segment continued its same-store sales performance momentum with year-over-year growth of 6.6%, and two-year cumulative growth of just under 10%. Higher average cheque drove much of our growth, benefiting from pricing in the system, and to a lesser extent, from favourable product mix. Targeted advertising and promotional efforts to increase brand awareness contributed to this strong performance.

We continue to focus restaurant development and enhanced advertising in our core growth markets. During the second quarter, we opened 10 new locations in the U.S., including a mix of standard, non-standard and self-serve kiosks.

The U.S. segment had second quarter operating income of $4.0 million, growing 12.0% compared to $3.6 million last year. Continued profitability improvement reflects higher rents and royalties and distribution income from continued systemwide sales growth. Planned incremental investments in advertising and marketing, and leveraging savings from previous closures in the New England region, also contributed to our overall U.S. segment performance.

Information on non-GAAP Measure

Operating income attributable to Tim Hortons Inc. is a non-GAAP measure. Operating income attributable to Tim Hortons Inc. excludes operating income attributable to noncontrolling interests. Prior to the adoption of a new accounting standard at the beginning of 2010, operating income was, for the most part, unaffected by noncontrolling interests, which was not the case post-adoption. This new accounting standard required the consolidation of variable interest entities of which we are considered to be the primary beneficiary, including Maidstone Bakeries up to the date of sale on October 29, 2010, as well as, on average, approximately 257 and 274 non-owned restaurants year-to-date 2011 and 2010, respectively. Previously, we did not consolidate Maidstone Bakeries and we consolidated approximately 120 non-owned restaurants, on average, in accordance with the prior accounting standard. Management believes that operating income attributable to Tim Hortons Inc. provides important information for comparison purposes to prior periods and for purposes of evaluating the Company’s operating income performance without the effects of the accounting standard.

The presentation of this non-GAAP measure is made with operating income, the most directly comparable U.S. GAAP measure. We present information excluding amounts related to this accounting standard as it is more reflective of the way we analyze our year-over-year results and how we manage and measure our performance internally. Therefore, this measure provides a more consistent view of management’s perspectives on underlying performance than the closest equivalent U.S. GAAP measure. The reconciliation of operating income, a GAAP measure, to operating income attributable to Tim Hortons Inc., a non-GAAP measure, is set forth in the table below.
