DineEquity, Inc. Reports First Quarter Fiscal 2016 Results

Company Reiterates Financial Performance Guidance for Fiscal 2016

First Quarter 2016 Summary

·Adjusted EPS (Non-GAAP) of $1.58

·GAAP EPS of $1.37

·Domestic system-wide comparable same-restaurant sales increased 1.5% at IHOP and decreased 3.7% at Applebee’s

·Generated strong free cash flow of approximately $39 million

·Returned a combined total of approximately $37 million to shareholders in share repurchases and a first quarter cash dividend

GLENDALE, Calif., May 5, 2016 — DineEquity, Inc. (NYSE: DIN), the parent company of Applebee’s Neighborhood Grill & Bar® and IHOP® restaurants, today announced financial results for the first quarter of fiscal 2016.

“We continued to generate strong free cash flow in the first quarter and returned the majority of it to our shareholders. We’re aggressively executing our plan to get Applebee’s back on track, including the most transformative platform launch in the brand’s history in the coming weeks.  We remain focused on building on IHOP’s momentum through the implementation of several strategic initiatives that address all aspects of enhancing the guest experience,” said Julia A. Stewart, Chairman and Chief Executive Officer of DineEquity, Inc.

Ms. Stewart concluded, “We are confident in the steps currently being taken to drive positive and sustainable sales and traffic at both brands, while remaining committed to returning the majority of free cash flow to our shareholders.”

First Quarter of Fiscal 2016 Financial Results

·Adjusted net income available to common stockholders was $29.1 million, or adjusted earnings per diluted share of $1.58, for the first quarter of 2016.  This compares to $31.1 million, or adjusted earnings per diluted share of $1.64, for the same period of 2015.  The decline in adjusted net income was mainly due to the expected increase in general and administrative expenses and the impact on gross profit from the sale of the remaining Applebee’s company-operated restaurants in the third quarter of 2015.  The decline was partially offset by fewer weighted average shares outstanding. (See “Non-GAAP Financial Measures” below.)

·GAAP net income available to common stockholders was $25.2 million for the first quarter of 2016, or earnings per diluted share of $1.37.  This compares to net income available to common stockholders of $28.0 million, or earnings per diluted share of $1.47, for the first quarter of 2015.  The decline was primarily due to the expected increase in general and administrative expenses and the impact on gross profit from the sale of the remaining Applebee’s company-operated restaurants in the third quarter of 2015.  These items were partially offset by fewer weighted average shares outstanding and a decline in closure and impairment charges.

·General and administrative expenses were $39.4 million for the first quarter of 2016.  This compares to $34.2 million for the same period of 2015.  The expected increase was mainly due to $2.1 million of non-recurring costs associated with the consolidation of our restaurant support center announced on September 3, 2015, higher personnel costs and an increase in costs for travel in the first quarter of 2016 compared to the first quarter of 2015.

Same-Restaurant Sales Performance

First Quarter of Fiscal 2016

·IHOP’s domestic system-wide same restaurant sales increased 1.5% for the first quarter of 2016 compared to the same period in 2015.

·Applebee’s domestic system-wide same-restaurant sales decreased 3.7% for the first quarter of 2016 compared to the first quarter of 2015.

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),” “free cash flow,” and “segment EBITDA.”  “Adjusted EPS” is computed for a given period by deducting from net income or loss available to common stockholders for such period the effect of any closure and impairment charges, any gain or loss related to debt extinguishment, any intangible asset amortization, any non-cash interest expense, any gain or loss related to the disposition of assets, and other items deemed not reflective of current operations.  This is presented on an aggregate basis and a per share (diluted) basis.  “Free cash flow” for a given period is defined as cash provided by operating activities, plus receipts from notes and equipment contracts receivable, less capital expenditures.  Management utilizes free cash flow to determine the amount of cash remaining for general corporate and strategic purposes and for the return of cash to stockholders pursuant to our capital allocation strategy, after the receipts from notes and equipment contracts receivable, and the funding of operating activities, capital expenditures and debt service. 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 and free cash flow 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 months ended March 31, 2016 and 2015, 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. 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, and, where applicable, rental payments under leases that  may be partially 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.

(a)   “Effective Restaurants” are the weighted average number of restaurants open in a given fiscal 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 franchisees and area licensees as well as those owned by the Company.

(b)   “System-wide” sales are retail sales at Applebee’s restaurants operated by franchisees and IHOP restaurants operated by franchisees and area licensees, as reported to the Company, in addition to retail sales at company-operated restaurants.  Sales at restaurants that are owned by franchisees and area licensees are not attributable to the Company. Unaudited reported sales for Applebee’s domestic franchise restaurants, IHOP franchise restaurants and IHOP area license restaurants for the three months ended March 31, 2016 and 2015 were as follows:

IHOP area license restaurant sales	75.3		$	75.0
Total	$	2,003.2	$	2,022.2

(c)   “Sales percentage change” reflects, for each category of restaurants, the percentage change in sales in any given fiscal period compared to the prior fiscal period for all restaurants in that category.

(d)   “Domestic same-restaurant sales percentage change” reflects the percentage change in sales, in any given fiscal period, compared to the same weeks in the prior year for domestic restaurants that have been operated throughout both fiscal periods that are being compared and have been open for at least 18 months. Because of new unit openings and restaurant closures, the domestic restaurants open throughout both fiscal periods being compared may be different from period to period. Same-restaurant sales percentage change does not include data on IHOP area license restaurants located in Florida.
