Dunkin’ Brands Reports Second Quarter 2012 Results

CANTON, Mass. (July 26, 2012) – Dunkin’ Brands Group, Inc. (Nasdaq: DNKN), the parent company of Dunkin’ Donuts (DD) and Baskin-Robbins (BR), today reported results for the second quarter ended June 30, 2012. “Tomorrow marks our one-year anniversary as a publicly-traded company. We believe our strong performance to date clearly demonstrates the platform for growth that we laid out at the time of our IPO,” said Nigel Travis, Chief Executive Officer, Dunkin’ Brands Group, Inc., and President, Dunkin’ Donuts U.S. “For the quarter, our franchised business model continued to generate consistent revenue growth and high-margins, resulting in a 32 percent increase in adjusted earnings per share. Additionally, our focus on store-level economics, best-in-class product and marketing innovation, and operational execution drove comparable store sales increases across all business segments. We also continued to capitalize on our significant growth prospects in the U.S. and internationally and by the end of the quarter had more than 17,000 restaurants worldwide.”

Global system-wide sales growth in the second quarter was primarily attributable to Dunkin’ Donuts U.S. comparable store sales growth (which includes stores open 54 weeks or more), global store development, and growth in Baskin-Robbins international sales.

Dunkin’ Donuts U.S. comparable store sales growth in the second quarter was driven by increased average ticket and higher traffic. The growth resulted from strong beverage sales growth led by cold beverages including Black Cocoa Crème Iced Coffee as part of the Men in Black™3 promotion and a national $0.99 Iced Tea offer; differentiated breakfast sandwich offerings such as the new Breakfast Burrito in Steak and Veggie varieties as well as the continuation of the Angus Steak, Egg and Cheese Breakfast Sandwich; continued growth in Bakery Sandwiches; sales of Dunkin’ Donuts K-Cup portion packs; and the “What Are You Drinkin’”^® marketing campaign.

Baskin-Robbins U.S. comparable store sales growth was driven by new product news around the return of signature Flavors of the Month including Lunar Cheesecake as part of the Men in Black™3 promotion, and Strawberry Lemonade; Mother’s and Father’s Day custom cake sales; and new beverages such as the Triple Chocolate Cappy Blast and Tropical Banana Smoothie.

In the second quarter, Dunkin’ Brands franchisees and licensees opened 140 net new restaurants across the globe. This includes 87 net new Baskin-Robbins International locations, 29 net new Dunkin’ Donuts International locations, 19 net new Dunkin’ Donuts U.S. locations, and 5 net new Baskin-Robbins U.S. locations. Additionally, Dunkin’ Donuts U.S. franchisees remodeled 156 restaurants during the quarter.

Revenues grew by 9.8 percent compared to the second quarter of 2011, primarily from increased royalty income driven by the increase in system-wide sales.

Operating income decreased $15.7 million, or 25.3 percent, from the second quarter of 2011 primarily as a result of a $20.7 million increase in the legal reserve related to the Bertico litigation and $3.7 million of costs related to the closing of the Peterborough, Ontario, Canada ice cream manufacturing plant, offset by the increase in revenues. Adjusted operating income increased $9.7 million, or 14.0 percent, from the second quarter of 2011 primarily as a result of the increase in revenues and continued general and administrative expense leverage.

Net income increased by $1.3 million compared to the second quarter of 2011 as a result of a decrease in interest expense associated with the refinancings completed last year and the repayment of our debt with the proceeds from our initial public offering, offset by the decrease in operating income. Adjusted net income increased by $15.6 million compared to the second quarter of 2011 as a result of the increase in adjusted operating income and the decrease in interest expense, offset by a corresponding increase in tax expense.

Company Updates

“We have made significant progress in driving supply chain efficiencies for both Dunkin’ Donuts and Baskin-Robbins while maintaining our high product quality,” said Neil Moses, Dunkin’ Brands Chief Strategy Officer. “Our decision to close our Baskin-Robbins plant in October is in keeping with this strategy. Moving our international ice cream production to a trusted, long-term dairy manufacturing partner is aligned with our asset-light model and is expected to generate significant annual savings for the Company. Most importantly, this transition will enable us to provide better support for our growing international Baskin-Robbins business.”

Fiscal Year 2012 Targets

As described below, the Company is increasing certain targets and reaffirming others that it has previously provided regarding its 2012 performance.

On the strength of this performance, we are increasing both our 2012 adjusted earnings per share and our global restaurant development targets,” said Paul Carbone, Dunkin’ Brands Chief Financial Officer. “Our highly-leverageable, franchised business model and significant white space growth opportunities uniquely position us to continue to grow our business and deliver shareholder value despite an increasingly challenging economic environment.”

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; 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 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.

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 pro forma common share, which present operating results on a basis adjusted for certain items and/or reflecting the conversion of our previously outstanding Class L common stock into shares of common stock. 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 pro forma common 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.”

On August 1, 2011, the Company completed an initial public offering in which the Company sold 22,250,000 shares of common stock at an initial public offering price of $19.00 per share. Immediately prior to the offering, each share of the Company’s Class L common stock converted into 2.4338 shares of common stock. The number of common shares used in the calculation of diluted adjusted earnings per pro forma common share for the three months ended June 25, 2011 gives effect to the conversion of all outstanding shares of Class L common stock at the conversion factor of 2.4338 common shares for each Class L share, as if the conversion was completed at the beginning of the fiscal period. The calculation of diluted adjusted earnings per pro forma common share also includes the dilutive effect of common restricted shares and stock options, using the treasury stock method. Diluted adjusted earnings per pro forma common share is calculated using adjusted net income, as defined above. See the attached table “Dunkin’ Brands Group, Inc. Diluted Adjusted Earnings per Pro Forma Common Share” for further detail.

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

The Company uses “System-wide 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 system-wide sales are driven by changes in average comparable store sales and changes in the number of restaurants.

5

The Company uses “DD U.S. comparable store sales growth,” “BR U.S. comparable store sales growth” and “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.
