DineEquity, Inc. Reports Third Quarter Results

Completes Applebee’s Refranchising Initiative

Significantly Reduces Total Debt by $167 Million

GLENDALE, Calif., October 30, 2012 — DineEquity, Inc. (NYSE: DIN), the parent company of Applebee’s Neighborhood Grill & Bar and IHOP Restaurants, today announced financial results for the third quarter of 2012.

“We are pleased with our results for the third quarter, which was highlighted by the great progress we made against our long-term strategic goals.  Earlier this month, we achieved a significant milestone with the completion of our transition to a fully-franchised restaurant system.  Our more efficient business model continued to generate strong free cash flow, enabling further debt reduction as we optimize our G&A structure to create additional value for our stockholders,” said Julia A. Stewart, Chairman and Chief Executive Officer of DineEquity, Inc.  “Our strategy at Applebee’s yielded solid performance in the third quarter, where our revitalization initiatives continue to fuel momentum.  We continued the hard work already underway at IHOP to restore same-restaurant sales growth. Most importantly, we have strong alignment with our IHOP franchisees to execute on our plan for improvement.”

Third Quarter 2012 Financial Highlights

·                  Total debt was reduced by $167.2 million in the third quarter of 2012 as a result of net cash proceeds and financing obligation reductions from the refranchise and sale of Applebee’s company-operated restaurants and free cash flow.  The Company reduced Term Loan balances by $106.1 million and financing and capital lease obligations by $61.1 million.

·                  Adjusted net income available to common stockholders was $18.9 million, representing adjusted earnings per diluted share of $1.03 for the third quarter of 2012. This compares to $19.1 million, or adjusted earnings per diluted share of $1.04, for the same quarter in 2011. The decrease in adjusted earnings was due to, as expected, lower segment profit caused by the execution of our strategy to refranchise Applebee’s company-operated restaurants. This item was partially offset by lower cash interest expense. (See “Non-GAAP Financial Measures” below.)

·                  GAAP net income available to common stockholders was $58.7 million, or earnings per diluted share of $3.14 for the third quarter of 2012, compared to $15.5 million, or earnings per diluted share of $0.85, for the same quarter in 2011.  The increase was primarily due to a higher gain on the refranchise and sale of Applebee’s company-operated restaurants and lower interest expense. These items were partially offset by higher income taxes, an increase in general and

administrative expenses, and, as expected, lower segment profit due to the refranchise and sale of Applebee’s company-operated restaurants.

·                  Consolidated general and administrative expenses were $48.7 million for the third quarter of 2012 compared to $38.7 million in the third quarter of 2011.  The increase was primarily due to a $9 million non-recurring litigation settlement and net severance charges associated with the Company’s previously announced restructuring initiative to lower general and administrative expenses by approximately $10 million to $12 million on an annualized basis.  These items were partially offset by the savings in employee compensation associated with the workforce reduction.

·                  Applebee’s company-operated restaurant operating margin was 15.5% for the third quarter of 2012 compared to 14.2% for the same quarter in 2011, an increase of 130 basis points.  The increase was primarily due to cessation of depreciation on restaurants held for sale, the refranchising of lower margin company-operated restaurants, and lower advertising expense.  These items were partially offset by higher labor expense and commodity inflation.

First Nine Months of 2012 Highlights

·                  Total debt was reduced by $255.5 million in the first nine months of 2012 as a result of net cash proceeds and financing obligation reductions from the refranchise and sale of Applebee’s company-operated restaurants and free cash flow.  The Company reduced Term Loan balances by $175.2 million, Senior Notes by $3.6 million, and financing and capital lease obligations by $76.7 million.

·                  Adjusted net income available to common stockholders was $62.6 million in the first nine months of 2012, representing adjusted earnings per diluted share of $3.44. This compares to $61.7 million, or adjusted earnings per diluted share of $3.37, for the same period in 2011.  The increase in adjusted earnings was due to lower cash interest expense, partially offset by, as expected, lower segment profit due to the refranchise and sale of Applebee’s company-operated restaurants and lower income taxes. (See “Non-GAAP Financial Measures” below.)

·                  GAAP net income available to common stockholders was $104.3 million in the first nine months of 2012, or earnings per diluted share of $5.66, compared to $43.4 million, or earnings per diluted share of $2.38 for the same period in 2011.  The increase was primarily due to a higher gain on the refranchise and sale of Applebee’s company-operated restaurants, lower impairment and closure charges, and lower interest expense.  These items were partially offset by higher income tax expense, an increase in general and administrative expenses, and, as expected, lower segment profit due to refranchising.

·                  EBITDA was $226.3 million for the first nine months of 2012. (See “Non-GAAP Financial Measures” below.)

·                  For the first nine months of 2012, cash flows from operating activities were $68.1 million, capital expenditures were $13.5 million, and free cash flow was $64.9 million.  (See “Non-GAAP Financial Measures” below.)

·                  Applebee’s company-operated restaurant operating margin was 16.8% for the first nine months of 2012 compared to 14.4% for the same period in 2011.  The increase of 240 basis points was primarily due to lower depreciation expense, improved control of waste, and the refranchising of lower margin company-operated restaurants.  These items were partially offset by commodity inflation, new menu related expense, and higher labor expense.

Refranchise and Sale of Applebee’s Company-Operated Restaurants

During the third quarter of 2012, DineEquity completed the sale of 33 and 65 Applebee’s company-operated restaurants to American Franchise Capital, LLC and TSFR Apple Venture, respectively.  After-tax net proceeds of approximately $87 million were used to retire debt.

On October 3, 2012, DineEquity completed the sale of 39 Applebee’s company-operated restaurants located in Virginia to Potomac Family Dining Group, LLC.  After-tax net proceeds of approximately $24 million were used to further reduce debt.

DineEquity has now completed its Applebee’s refranchising program and transitioned to a 99% franchised restaurant system and is now considered to be fully franchised.  As a result, DineEquity’s business model is less capital intensive with higher operating margins and the Company expects to have cash flow with substantially reduced volatility over time.  The Company currently retains 23 Applebee’s company-operated restaurants in the Kansas City area for test market purposes.

Same-Restaurant Sales Performance

Third Quarter 2012

·                  Applebee’s domestic system-wide same-restaurant sales increased 2.0% for the third quarter of 2012 compared to the third quarter of 2011.  The increase in same-restaurant sales reflected a higher average guest check, partially offset by a decline in traffic compared to the third quarter of 2011.

·                  IHOP’s domestic system-wide same restaurant sales decreased 2.0% for the third quarter of 2012 compared to the third quarter of 2011.  The decline in same-restaurant sales reflected a decline in traffic, partially offset by a slightly higher average guest check compared to the third quarter of 2011.

First Nine Months of 2012

·                  Applebee’s domestic system-wide same-restaurant sales increased 1.3% in the first nine months of 2012 compared to the same period in 2011.  The increase in same-restaurant sales was mainly driven by a higher average guest check, partially offset by a decline in traffic compared to the first nine months of 2011.

·                  IHOP’s domestic system-wide same-restaurant sales declined 1.3% in the first nine months of 2012 compared to the same period in 2011.  The decline in same-restaurant sales reflected a decline in traffic, partially offset by a higher average guest check compared to the first nine months of 2011.

Non-GAAP Financial Measures

This news release includes references to the Company’s non-GAAP financial measures “adjusted net income available to common stockholders (adjusted EPS),” “EBITDA,” “free cash flow,” and “segment EBITDA.” “Adjusted EPS” is computed for a given period by deducting from net income (loss) available to common stockholders for such period the effect of any impairment and closure charges, any gain or loss related to debt extinguishment, any intangible asset amortization, any non-cash interest expense, any debt modification costs, any one-time litigation settlement charges, any general and administrative restructuring costs, net of savings, any gain or loss related to the disposition of assets, and any state income tax impact of deferred taxes due to refranchising incurred in such period. This is presented on an aggregate basis and a per share (diluted) basis. The Company defines “EBITDA” for a given period is defined as income before income taxes less interest expense, loss on retirement of debt, depreciation

and amortization, impairment and closure charges, non-cash stock-based compensation, gain/loss on disposition of assets and other charge backs as defined by its credit agreement. “Free cash flow” for a given period is defined as cash provided by operating activities, plus receipts from notes and equipment contracts receivable (“long-term notes receivable”), less dividends paid and capital expenditures. “Segment EBITDA” for a given period is defined as gross segment profit plus depreciation and amortization as well as interest charges related to the segment. Management utilizes EBITDA for debt covenant purposes and free cash flow to determine the amount of cash remaining for general corporate and strategic purposes after the receipts from long-term notes receivable, and the funding of operating activities, capital expenditures and preferred dividends. Management believes this information is helpful to investors to determine the Company’s adherence to debt covenants and the Company’s cash available for these purposes. Adjusted EPS, EBITDA, free cash flow and segment EBITDA are supplemental non-GAAP financial measures and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with United States generally accepted accounting principles.

Restaurant Data

The following table sets forth, for the three and nine months ended September 30, 2012 and 2011, the number of effective restaurants in the Applebee’s and IHOP systems and information regarding the percentage change in sales at those restaurants compared to the same periods in the prior year. “Effective restaurants” are the number of restaurants in a given period, adjusted to account for restaurants open for only a portion of the period. Information is presented for all effective restaurants in the Applebee’s and IHOP systems, which includes restaurants owned by the Company, as well as those owned by franchisees and area licensees. Sales at restaurants that are owned by franchisees and area licensees are not attributable to the Company. However, we believe that presentation of this information is useful in analyzing our revenues because franchisees and area licensees pay us royalties and advertising fees that are generally based on a percentage of their sales, as well as rental payments under leases that are usually based on a percentage of their sales. Management also uses this information to make decisions about future plans for the development of additional restaurants as well as evaluation of current operations.
