Dunkin’ Brands Reports First Quarter 2012 Results

CANTON, Mass. (April 26, 2012) – Dunkin’ Brands Group, Inc. (Nasdaq: DNKN), the parent company of Dunkin’ Donuts (DD) and Baskin-Robbins (BR), today reported results for the first quarter ended March 31, 2012. “We’re pleased with the performance of the business in the first quarter during which we had continued strong revenue and operating income growth. Our core Dunkin’ Donuts U.S. segment is thriving with 7.2 percent comp store sales growth and accelerating net development compared to the first quarter of 2011,” said Nigel Travis, Chief Executive Officer, Dunkin’ Brands Group, Inc., and President, Dunkin’ Donuts U.S. “We also recently announced several exciting strategic developments including an agreement with The Coca-Cola Company to serve its products in Dunkin’ Donuts and Baskin-Robbins restaurants in the U.S., an agreement with NBA star LeBron James to serve as a brand ambassador in select Southeast Asia markets for both brands, and signing a partnership with Dallas Cowboys Owner Jerry Jones and Hall of Fame quarterback Troy Aikman to develop Dunkin’ Donuts restaurants in the Dallas/Fort Worth region.”

Consolidated Key Highlights

(amounts and percentages may not recalculate due to rounding)

Worldwide system-wide sales growth in the first 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 gains in the first quarter were driven by increased average ticket and higher traffic resulting from strong beverage sales growth including gains across all cold beverages; differentiated breakfast and afternoon sandwich offerings such as the Angus Steak, Egg and Cheese Breakfast Sandwich and the Turkey, Bacon and Cheddar, and Ham and Cheese 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 Valentine’s Day Cake Bites, a new “More Flavors, More Fun” advertising campaign, and improved operational execution.

In the first quarter, Dunkin’ Brands franchisees and licensees opened 82 net new restaurants across the globe. This includes 45 net new Dunkin’ Donuts U.S. locations and 49 net new Baskin-Robbins International locations. Both Baskin-Robbins U.S. and Dunkin’ Donuts International experienced declining store counts in the first quarter. Additionally, Dunkin’ Donuts U.S. franchisees remodeled 108 restaurants during the quarter.

Revenues grew by 9.5 percent compared to the first quarter of 2011, primarily from increased royalty income driven by the increase in system-wide sales.

Operating income and adjusted operating income increased $10.4 million, or 23.1 percent, and $10.4 million, or 19.8 percent, respectively, from the first quarter of 2011 primarily as a result of the increase in revenues and higher income from our joint ventures.

Net income and adjusted net income increased by $27.7 million and $21.1 million, respectively, compared to the first quarter of 2011 as a result of the increase in operating income and 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.

Company Updates & Fiscal Year 2012 Targets

On March 5, 2012, the Company’s Board of Directors approved the initiation of a quarterly cash dividend with the first quarter cash dividend of $0.15 per share paid on March 28, 2012 to shareholders of record as of the close of business on March 19, 2012. The Company today announced that the Board of Directors declared a second quarter cash dividend of $0.15 per share, payable on May 16, 2012 to shareholders of record as of the close of business on May 7, 2012.

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

Forward-looking statements reflect management’s analysis as of the date of this press release. Important factors that could cause actual results to differ materially from our expectations are more fully described in our other filings with the Securities and Exchange Commission, including under the section headed “Risk Factors” in our most recent annual report on Form 10-K. 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 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 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 March 26, 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.

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.
