DineEquity, Inc. Reports Second Quarter 2008 Same-Store Sales

Results for Its IHOP and Applebee’s Businesses

GLENDALE, Calif., July 10, 2008 —   DineEquity, Inc. (NYSE: DIN), franchisor and operator of Applebee’s Neighborhood Grill & Bar and IHOP Restaurants, today reported same-store sales results for the second quarter ended June 30, 2008 for its IHOP and Applebee’s business units.  IHOP’s system-wide same-store sales increased 2.6% for the second quarter 2008 and increased 3.2% for the first six months of fiscal 2008.  Applebee’s system-wide domestic same-store sales decreased 1.7% for the second quarter 2008 and decreased 0.6% for the first six months of fiscal 2008.

Julia A. Stewart, DineEquity’s chairman and chief executive officer, said, “We are pleased to report IHOP’s 22^nd consecutive quarter of same-store sales growth as we continue our year-long celebration of  IHOP’s 50^th birthday.  IHOP’s growth was supported primarily by unique limited-time offers such as Tour de French Toast and Discover America Pancakes.  Additionally, during the second quarter 2008, we introduced new advertising to support IHOP’s non-breakfast offerings, and teamed up with Minor League Baseball^TM for a cross-country promotional road tour.

“While we are on track with our plans to re-energize the Applebee’s brand, we experienced a challenging second quarter 2008.  We are still in the early stages of implementing brand and operational improvements, which we believe will ultimately lead to longer-term, sustainable same-store sales growth within the Applebee’s system.  We have built a solid foundation with our recently completed brand positioning and customer targeting projects.  We have rolled out a new advertising campaign built around the theme ‘It’s a Whole New Neighborhood.’  We are establishing a pipeline of new and appealing, value-oriented offerings based on our guests’ favorite items, and will begin to promote these promising performers in the second half of the year.  Applebee’s second quarter 2008 same-store sales results reflected traffic declines at company-operated restaurants, which offset an increased average guest check that was primarily driven by an effective pricing increase of nearly 3%, favorable mix-shift, and the benefit of sales contests employed at company-operated restaurants,” Stewart said.

IHOP’s system-wide same-store sales increase of 2.6% for the second quarter 2008 reflected a higher average guest check and modestly positive guest traffic growth.  As of June 30, 2008, there were 1,361 IHOP restaurants operating system-wide in 49 states, Canada and Mexico, 10 of which were company-operated in IHOP’s dedicated research and development market of Cincinnati, Ohio.

Same-store-sales for Applebee’s domestic franchised restaurants decreased 1.8% for the second quarter 2008 and decreased 0.9% for the first six months of fiscal 2008.  Same-store-

sales for Applebee’s Company-operated restaurants decreased 1.5% for the second quarter 2008 and increased 0.3% for the first six months of fiscal 2008.  As of June 30, 2008, there were 1,993 Applebee’s restaurants operating system-wide in 49 states, 17 international countries, and one U.S. territory, of which 509 were company-owned.

DineEquity reiterated its expectations of producing system-wide same-store sales growth at IHOP in the range of 2% to 4% for fiscal 2008.  The Company revised its system-wide domestic same-store sales growth expectations for Applebee’s to range between negative 1% and positive 1% for fiscal 2008 versus its previous growth expectations in the range of 1% to 2% for fiscal 2008.

Stewart said, “Our revised same-store sales outlook for Applebee’s takes into consideration the early stage implementation of our brand re-energizing and operational improvement strategies and our same-store sales performance in the first half of 2008.  Our outlook also reflects conservative performance expectations for Applebee’s value-oriented strategies that we expect to employ in the second half of the year.”

DineEquity will release full second quarter 2008 financial results Tuesday, July 29, 2008 before the market opens, and will host an investor conference call to discuss its second quarter 2008 financial results on the same day at 11:00 a.m. Eastern Time (8:00 a.m. Pacific Time).  To participate on the call, please dial (888) 680-0869 and reference pass code 35984516.
