¹ Adjusted operating income, adjusted operating income margin, and adjusted net income are non-GAAP measures reflecting operating income and net income adjusted for amortization of intangible assets, impairment charges, and other non-recurring, infrequent, or unusual charges, net of the tax impact of such adjustments in the case of adjusted net income. Diluted adjusted earnings per share is a non-GAAP measure calculated using adjusted net income. Please refer to “Non-GAAP Measures and Statistical Data” and “Dunkin' Brands Group, Inc. Non-GAAP Reconciliations” for further detail.

Global systemwide sales growth in the second quarter was primarily attributable to global store development and Dunkin' Donuts U.S. comparable store sales growth (which includes stores open 54 weeks or more).

Dunkin' Donuts U.S. comparable store sales growth in the second quarter was driven by increased average ticket and higher traffic resulting from our continued product and marketing innovation. This includes strong beverage growth, led by cold beverage news such as the introduction of Iced Coffee flavors inspired by Baskin-Robbins Ice Cream as well as Berry Blast, Minute Maid® and Hot Chocolate Coolatta flavors; continued momentum across the breakfast sandwich platform highlighted by the national expansion of the Turkey Sausage Breakfast Sandwich in May; growth in donut sales led by a successful National Donut Day program; and growth in afternoon products including new Chicken and Tuna Salad Wraps and new Chicken Sandwiches.

Baskin-Robbins U.S. comparable store sales growth was driven by sales of Flavors of the Month, including Jamoca Heath, Blueberry Shortbread, and Triple Vanilla; increased sales of cakes around Mother's Day, Father's Day and graduation season; and limited time offers on take-home ice cream quarts.

In the second quarter, Dunkin' Brands franchisees and licensees opened 151 net new restaurants around the globe. This includes 63 net new Dunkin' Donuts U.S. locations, 50 net new Baskin-Robbins International locations, 33 net new Dunkin' Donuts International locations, and five net new Baskin-Robbins U.S. locations. Additionally, Dunkin' Donuts U.S. franchisees remodeled 141 restaurants during the quarter.

Revenues for the second quarter increased 5.9 percent compared to the prior year primarily from increased royalty income from the increase in systemwide sales, as well as increased sales of ice cream products.

Operating income for the second quarter increased $30.7 million, or 66.5 percent, from the prior year primarily as a result of a $20.7 million increase in the Bertico litigation reserve in the prior year, the increase in royalty income, and a gain recognized on the sale of 80 percent of our Baskin-Robbins Australia business, offset by a one-time $7.5 million charge related to a third-party product volume guarantee. Adjusted operating income increased $12.2 million, or 15.5 percent, from the second quarter of 2012 also as a result of the increase in royalty income and the gain from the Baskin-Robbins Australia sale.

Net income for the second quarter increased by $22.3 million, or 120.6 percent, compared to the prior year primarily as a result of the $30.7 million increase in operating income, offset by a $4.4 million increase in income tax expense and a $3.2 million increase in interest expense. Adjusted net income increased by $3.6 million, or 8.8 percent, compared to the second quarter of 2012 as a result of the increase in adjusted operating income, offset by increases in interest expense and income tax expense.

Diluted adjusted earnings per share increased by 24.2 percent to $0.41 for the second quarter of 2013, as a result of the increase in adjusted net income, as well as a decline in shares outstanding due to the repurchase of 15 million shares in August 2012 and approximately 400,000 shares repurchased under previous authorizations during the second quarter of 2013.

Dunkin' Donuts U.S. revenues of $128.7 million represented an increase of 4.9 percent year-over-year. The increase in revenue was primarily a result of increased royalty income, offset by a decrease in rental income and franchise renewal fees.

Dunkin' Donuts U.S. segment profit in the second quarter decreased $2.9 million over the prior year to $87.1 million. This decrease was driven by a one-time $7.5 million charge related to a volume guarantee with the franchisee-owned supply chain cooperative regarding sales of cooler beverages in our restaurants, offset by revenue growth.

Dunkin' Donuts International systemwide sales increased 3.5 percent from the prior year period, driven by sales growth in Germany and Southeast Asia, offset by a decline in sales in South Korea. On a constant currency basis, systemwide sales increased by approximately 2 percent.

Dunkin' Donuts International revenues were consistent with the prior year period at $3.9 million, as the increase in royalty income driven by the increase in systemwide sales was offset by a decline in franchise fees.

Segment profit for Dunkin' Donuts International declined 17.9 percent to $1.6 million, primarily from investments in personnel and marketing for the Dunkin' Donuts International business, as well as losses realized from our new joint venture in Spain.

Baskin-Robbins U.S. revenue declined 2.0 percent from the prior year period to $12.5 million primarily from a decline in rental income due to a decline in the number of leased locations and a decline in refranchising gains, offset by an increase in royalty income driven by a 2.0 percent increase in systemwide sales as a result of comparable store sales growth of 1.6 percent.

Segment profit for the Baskin-Robbins U.S. segment decreased $0.9 million, or 10.2 percent, year-over-year primarily as a result of investments in advertising and other brand-building activities, as well as the decline in total revenues, offset by a decrease in occupancy expense for franchised restaurants consistent with the decline in rental income.

Baskin-Robbins International systemwide sales decreased 3.8 percent from the prior year period driven by an unfavorable impact of exchange rates on sales in Japan, offset by sales growth in South Korea. On a constant currency basis, systemwide sales increased by approximately 4 percent.

Baskin-Robbins International revenues increased 16.0 percent year-over-year to $34.9 million primarily from the sale of ice cream and related products to our new Australian joint venture in conjunction with the sale of 80 percent of our Baskin-Robbins Australia business, as well as increased sales of ice cream products to the Middle East.

Segment profit increased 64.1 percent year-over-year to $19.4 million, primarily resulting from the gain recognized on the sale of the Baskin-Robbins Australia business and an increase in net margin on ice cream driven by the increase in sales, as well as an increase in income from our South Korean joint venture.

Forward-Looking Statements

Certain statements contained herein are not based on historical fact and are “forward-looking statements” within the meaning of the applicable securities laws and regulations.  Generally, these statements can be identified by the use of words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “feel,” “forecast,” “intend,” “may,” “plan,” “potential,” “project,” “should,” “would,” and similar expressions intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.   By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future.  These risk and uncertainties include, but are not limited to: the ongoing level of profitability of franchisees and licensees; our franchisees' and licensees' ability to sustain same store sales growth; changes in working relationships with our franchisees and licensees and the actions of our franchisees and licensees; our master franchisees' relationships with sub-franchisees; the strength of our brand in the markets in which we compete; changes in competition within the quick-service restaurant segment of the food industry; changes in consumer behavior resulting from changes in technologies or alternative methods of delivery; economic and political conditions in the countries where we operate; our substantial indebtedness; our ability to protect our intellectual property rights; consumer preferences, spending patterns and demographic trends; the impact of seasonal changes, including weather effects, on our business; the success of our growth strategy and international development; changes in commodity and food prices, particularly coffee, dairy products and sugar, and other operating costs; shortages of coffee; failure of our network and information technology systems; interruptions or shortages in the supply of products to our franchisees and licensees; the impact of food borne-illness or food safety issues or adverse public or media opinions regarding the health effects of consuming our products; our ability to collect royalty payments from our franchisees and licensees; the ability of our franchisees and licensees to open new restaurants and keep existing restaurants in operation; our ability to retain key personnel; any inability to protect consumer credit card data and catastrophic events.

Except as required by applicable law, we do not undertake to publicly update or revise any of these forward-looking statements, whether as a result of new information, future events or otherwise.

Non-GAAP Measures and Statistical Data

In addition to the GAAP financial measures set forth in this press release, the Company has included certain non-GAAP measurements, adjusted operating income, adjusted operating income margin, adjusted net income, and diluted adjusted earnings per share, which present operating results on a basis adjusted for certain items. The Company uses these non-GAAP measures as key performance measures for the purpose of evaluating performance internally. We also believe these non-GAAP measures provide our investors with useful information regarding our historical operating results. These non-GAAP measures are not intended to replace the presentation of our financial results in accordance with GAAP. Use of the terms adjusted operating income, adjusted operating income margin, adjusted net income, and diluted adjusted earnings per share may differ from similar measures reported by other companies. Adjusted operating income and adjusted net income are reconciled from the respective measures determined under GAAP in the attached table “Dunkin' Brands Group, Inc. Non-GAAP Reconciliation.”

Additionally, the Company has included metrics such as systemwide sales growth and comparable store sales growth, which are commonly used statistical measures in the quick-service restaurant industry and are important to understanding the Company's performance.

The Company uses “systemwide sales growth” to refer to the percentage change in sales at both franchisee- and company-owned restaurants from the comparable period of the prior year. Changes in systemwide sales are driven by changes in comparable store sales and changes in the number of restaurants.

The Company uses “DD U.S. comparable store sales growth,” “BR U.S. comparable store sales growth,” “DD International comparable store sales growth,” and "BR International comparable store sales growth," which are calculated by including only sales from franchisee- and company-owned restaurants that have been open at least 54 weeks and that have reported sales in the current and comparable prior year week.
