SONIC REPORTS THIRD QUARTER EARNINGS

Significant Progress Achieved on Refranchising Initiative

OKLAHOMA CITY (June 23, 2009) – Sonic Corp. (NASDAQ: SONC), the nation's largest chain of drive-in restaurants, today announced results for the third fiscal quarter of 2009, which ended on May 31, 2009.  Key aspects of the company's third quarter report included:

·   Net income per diluted share for the quarter totaled $0.27, a slight decline from the same quarter last year;

·   System-wide same-store sales declined 5.4% for the third quarter; same-store sales at partner drive-ins (those in which the company owns a majority interest) declined 7.7% in the quarter;

·   System-wide new drive-in openings totaled 34 compared with 41 in the third quarter last year, reflecting primarily the company's recent decision to moderate partner drive-in development; franchisees opened 32 drive-ins versus 35 drive-ins in the same period last year; and

·   The refranchising of 177 partner drive-ins during the quarter, including 82 in which the company retained a minority interest in the operations; these transactions bring to 194 the total number of drive-ins refranchised through the first nine months of fiscal 2009.

"The challenging consumer environment continued to affect our sales performance in the third quarter," said Clifford Hudson, Chairman and Chief Executive Officer.  "We continue to strive for greater balance in our menu, emphasizing promotions that will drive traffic, loyalty and check.  Our June promotion, featuring a free upgrade to a Route 44 drink with any combo meal, is designed to boost combo sales, which are an important component in driving higher check amounts.  This promotion, together with other premium product promotions and our newly implemented Everyday Value Menu, is intended to improve sales over the summer with a balance of traffic and check."

Hudson noted the recent refranchising of 177 partner drive-ins was a key accomplishment in the third quarter.  These transactions increase the mix of franchised drive-ins to approximately 86% of the chain versus 80% at the beginning of the fiscal year.  "The speed with which we have been able to implement our refranchising initiative, along with the solid pace of our development in spite of current pressures on the credit markets, reflects the ongoing confidence our franchisees have in our brand," he said.

Hudson added, "We believe this change in our business model ultimately will benefit our partner drive-in performance by allowing greater focus on a smaller base, and will benefit our stockholders by reducing the operational and financial risks of our business.  Increased franchise royalty and rental revenue will provide a more consistent and recurring cash flow model for our company."  Hudson noted that the company has a strong cash position and solid cash flow from operations.  Sonic will continue to consider opportunistic purchases of outstanding debt to strengthen its balance sheet, or other stockholder-value initiatives, using available cash and proceeds from its refranchising efforts.

Income Statement Overview

For the third quarter ended May 31, 2009, revenues declined 10% to $191.9 million from $213.0 million in the year-earlier period, reflecting lower restaurant sales at partner drive-ins as well as the impact of refranchising on the company's revenue mix.  Net income for the quarter was $16.8 million or $0.27 per diluted share, declining slightly from $17.2 million or $0.28 per diluted share in the same quarter last year.  For the first nine months of the fiscal year, revenues declined 6% to $545.0 million from $577.8 million in the prior year.  Net income on a year-to-date basis was $32.6 million or $0.53 per diluted share compared with $40.1 million or $0.64 per diluted share for the comparable period last year.

The non-GAAP adjustments outlined below are intended to supplement the presentation of the company's financial results in accordance with GAAP.  The company believes that the presentation of these items provides useful information to investors and management regarding the underlying business trends and the performance of the company's ongoing operations and is helpful for period-to-period and company-to-company comparisons, which management believes will assist investors in analyzing the financial results of the company and predicting future performance.

During the third quarter ended May 31, 2009, the company recognized a $10.8 million pre-tax gain from refranchising partner drive-ins, which was partially offset by a $7.5 million pre-tax impairment charge.  Excluding these special items, net income and net income per diluted share for the third quarter declined 15% and 14%, respectively.

During the nine months ended May 31, 2009, the company recognized a $10.9 million pre-tax gain from refranchising partner drive-ins and a $6.4 million gain from the purchase of debt at a discount, which was partially offset by a $7.9 million pre-tax impairment charge.  Excluding these special items, net income and net income per diluted share for the nine months declined 33% and 31%, respectively.

Same-Store Sales

For the third fiscal quarter ended May 31, 2009, system-wide same-store sales declined 5.4% versus a decline of 0.4% for the same quarter last year, reflecting 4.9% lower same-store sales at franchise drive-ins and a 7.7% decline at partner drive-ins.  For the first nine months of fiscal 2009, system-wide same-store sales declined 4.3% versus an increase of 1.5% in the prior-year period.  The decline in system-wide same-store sales reflected 3.7% lower same-store sales at franchise drive-ins and a 6.8% decline at partner drive-ins.

Development

System-wide drive-in openings totaled 34 in the third quarter, including 32 franchise drive-ins, versus 41 new drive-in openings during the third quarter of fiscal 2008, including 35 by franchisees.  For the first nine months of fiscal 2009, system-wide drive-in openings totaled 100, including 90 franchise drive-ins, versus 111 in the year-earlier period, including 95 franchise drive-ins.  Sonic expects to open approximately 130 to 135 drive-ins during fiscal 2009.

Concluding Comments

"While our sales were lower than we expected in the third quarter, we believe our continued emphasis on distinctive promotions that drive traffic, loyalty and check – in concert with our unique quality and customer service experience – will improve sales over the long run," Hudson said.  "Sonic has always been about choice, with a diverse and unique menu selection that stands out among quick-service restaurants, and we know our customers expect value alongside the signature premium selections we offer.  So the long-term interests of our brand – and those of our company and franchisees – demand that we remain patient with the implementation of new menu strategies, especially considering the volatile consumer environment we face.   This is the right course for Sonic in terms of building our brand, laying the foundation for national expansion, and positioning our company for future growth when the recession subsides."
