FOR IMMEDIATE RELEASE

Dunkin’ Brands Reports Fourth Quarter and Full Year 2011 Results

Strong finish to 2011 with fourth quarter adjusted net income* up 36.6% driven by 7.4% Dunkin' Donuts U.S. comp store sales increase

CANTON, Mass. (February 9, 2012) – Dunkin’ Brands Group, Inc. (Nasdaq: DNKN), the parent company of Dunkin’ Donuts (DD) and Baskin-Robbins (BR), today reported results for the fourth quarter and fiscal year ended December 31, 2011, periods that included 14 weeks and 53 weeks, respectively.

“We had a strong finish to the year. Our operational execution, innovative product introductions, and break-through marketing are differentiating us competitively and delivering results,” said Nigel Travis, Chief Executive Officer, Dunkin’ Brands Group, Inc., and President, Dunkin’ Donuts U.S. “We continue to grow our brands globally, adding more than 600 net new Dunkin’ Donuts and Baskin-Robbins locations last year. The long-term agreement we signed with our Dunkin’ Donuts franchisee-owned procurement and distribution cooperative was a significant step forward in support of our goal to accelerate the growth of the brand across the U.S. In 2011, we executed our strategy, remained laser-focused on our priorities, and we believe we have positioned the Company to deliver sustainable long-term growth.”

Fourth quarter highlights include:

Fiscal year 2011 highlights include:

Worldwide system-wide sales growth in the fourth quarter was primarily attributable to Dunkin’ Donuts U.S. comparable store sales growth (which includes stores open 54 weeks or more), global store development, growth in Baskin-Robbins international sales, and the impact of the extra week in 2011.

Dunkin’ Donuts U.S. comparable store sales gains in the fourth quarter were driven by increased average ticket and higher traffic resulting from strong beverage sales growth; differentiated breakfast sandwich limited time offers, including the Smoked Sausage Breakfast Sandwich; 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 holiday cakes and cake bites as well as improvements in operational execution.

In the fourth quarter, Dunkin’ Brands franchisees and licensees opened 120 net new Dunkin’ Donuts locations in the U.S. – with more than 80 percent of net openings located outside of the brand’s core markets – and 184 net Dunkin’ Donuts and Baskin-Robbins locations outside the U.S. Additionally, Dunkin’ Donuts U.S. franchisees remodeled 248 restaurants during the quarter and 636 during fiscal year 2011.

Revenues grew by 12.5 percent, or 7.2 percent on a 13-week basis, in the fourth quarter compared to the fourth quarter of 2010, primarily from increased royalty income driven by the increase in system-wide sales, as well as sales of ice cream products.

Operating income was modestly favorable over the fourth quarter of 2010 as a result of the increase in revenues offset by an $18.8 million net non-cash impairment charge related to the Company’s investment in the South Korean joint venture, driven by the performance of the Dunkin’ Donuts business in that country. Adjusted operating income grew 31.2 percent as a result of the leverage enabled by 12.5 percent revenue growth and minimal expense growth.

Net income increased by $26.8 million compared to the fourth quarter of 2010 as a result of a decrease in loss on debt extinguishment and costs associated with the Company’s refinancing in November 2010, offset by an increase in tax expense. Adjusted net income increased $9.7 million, or 36.6 percent, resulting primarily from increased adjusted operating income and a decrease in interest expense, partially offset by an increase in tax expense.

“We had an outstanding 2011, delivering full-year results which exceeded our long-term targets for both revenue and adjusted operating income,” said Neil Moses, Dunkin’ Brands Chief Financial Officer. “Our asset-light franchised business model produced significant revenue growth, high margins and strong free cash flow – as evidenced by the more than $100 million in cash we generated in 2011. We are excited about our prospects and remain focused on executing our growth strategies and delivering shareholder value.”

These forward-looking statements include all matters that are not historical facts. 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; changes in working relationship 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 the 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; inability to recover our capital costs; changes in political, legal, economic or other factors in international markets; termination of a master franchise agreement or contracts with the U.S. military; currency exchange rates; the impact of food borne-illness or food safety issues or adverse public or medial opinions regarding the health effects of consuming our products; our ability to collect royalty payments from our franchisees and licensees; uncertainties relating to litigation; changes in regulatory requirements to our and our franchisees and licensees ability to comply with current or future regulatory requirements; review and audit of certain of our tax returns; 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 provided certain non-GAAP measurements, adjusted operating income, adjusted operating income margin, adjusted net income, diluted earnings per pro forma common share, 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 Class L common stock into common. 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 measurements 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 earnings per pro forma common share, diluted adjusted earnings per pro forma common share may differ from similar measures reported by other companies. Adjusted operating income, adjusted operating income margin, 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 22,250,000 shares of common stock were sold 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 calculations of diluted earnings per pro forma common share and diluted adjusted earnings per pro forma common share for the fiscal year ended December 31, 2011 and the three months and fiscal year ended December 25, 2010 give 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 respective fiscal period. The calculations of diluted earnings per pro forma common share and diluted adjusted earnings per pro forma common share also include the dilutive effect of common restricted shares and stock options, using the treasury stock method. Shares sold in the offering are included in the diluted earnings per pro forma common share and diluted adjusted earnings per pro forma common share calculations beginning on the date that such shares were actually issued. 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 Earnings and Adjusted Earnings per Pro Forma Common Share” for further detail.

Additionally, the Company has included metrics such as worldwide 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.

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

Fiscal year 2011 and the fourth quarter of 2011 include 53 weeks and 14 weeks, respectively. Certain financial measures and other metrics in this release have been presented on a 52-week and 13-week basis for fiscal year 2011 and the fourth quarter of 2011, respectively, to provide improved comparability to the respective prior year periods. Such financial measures and metrics reflect our estimate of the impact of the additional week on system-wide sales, revenues, and expenses.
