SONIC REPORTS IMPROVED YEAR-END RESULTS
AS EARNINGS PER SHARE INCREASE 14% FOR FISCAL 2003

Record Number of New Drive-In Openings Help Push Revenues and Earnings Higher

OKLAHOMA CITY (October 14, 2003) – Sonic Corp. (NASDAQ/NM: SONC) today reported higher revenues and earnings for the fourth quarter and fiscal year ended August 31, 2003. Highlighting the company’s performance for the quarter and year was an acceleration in the rate of new drive-in openings, which reached a record level in fiscal 2003. New drive-ins not only contributed to the company’s increased sales for the periods, they also pushed franchising income up solidly, since the majority of new Sonic Drive-Ins are developed by franchisees.

        Net income for the fourth quarter of fiscal 2003 increased 8% to $17.5 million from $16.1 million in the same period last year. On a diluted per share basis, net income rose 13% to $0.43 versus $0.38 last year. Revenues for the quarter were up 13% to $135.1 million compared with $120.0 million in the fourth quarter last year.

        Net income for fiscal 2003 rose 10% to $52.3 million from $47.7 million for fiscal 2002. On a diluted per share basis, net income rose 14% to $1.29 versus $1.13 last year. Revenues for the year increased 12% to $446.6 million from $400.2 million in fiscal 2002.

        “We are pleased to announce continued growth in the Sonic brand during the past year, as the chain grew to more than 2,700 locations and produced system-wide sales, which includes both company-owned and franchise stores, of almost $2.4 billion – both up handsomely from a year ago,” said Clifford Hudson, Chairman and Chief Executive Officer. “This performance underscores the strength of our multi-layered growth strategies, as new unit development and its positive impact on franchising income helped compensate for somewhat slower same-store sales than we originally anticipated. Similarly, our ongoing ability to leverage corporate-level expenses helped offset to some extent margin pressures at the drive-in level caused by our planned investment in store management, as well as higher costs for such items as workers’ compensation and health care insurance. Together, these strategies produced strong growth in cash flow to support both development and our share repurchase program, the latter of which, in turn, had a beneficial effect on earnings per share.”

        Sonic’s system-wide same-store sales declined 0.7% in the fourth quarter and were down 0.3% for the full year, reflecting, at least in part, an uncertain economy and tentative consumer spending. After a slow start to the fourth quarter in June, estimated system-wide same store sales improved in July and August, returning to the lower end of the company’s targeted growth range of 1% to 3% as strong increases in traffic counts more than offset a decline in average check amount. This positive sales momentum continued through September and the first part of October, with an estimated increase in system-wide same-store sales that is within the company's targeted range.

        During the fourth quarter, Sonic opened 68 new drive-ins, including 60 by franchisees. This pace was well ahead of the 64 drive-ins opened in the same quarter last year, which included 51 by franchisees. For the full fiscal year, Sonic opened a record 194 new drive-ins, including 159 by franchisees, versus 182 drive-ins opened in fiscal 2002, including 142 by franchisees. “We are gratified by the confidence our operators continue to demonstrate for the Sonic brand, as seen by the record number of franchise store openings during the past year,” Hudson added. “We think this trend – this record pace – will likely continue in the coming year as we plan for an estimated 200 new drive-in openings, including 165 to 170 by our franchisees.”

        Concluding, Hudson said, “As the new fiscal year begins, we think the fundamental health of our business remains quite strong. Moreover, we believe that evolving consumer preferences will work in our favor as we continue our efforts to keep the Sonic brand relevant and compelling to consumers through our unique blend of high quality, differentiated products and superior service. These initiatives will include our ongoing development of new products that keep the brand fresh, as well as media expenditures that will increase from $100 million during fiscal 2002 to an estimated $110 million in the coming year, including significant growth in network cable advertising. Additionally, as we work to build average unit volume, we will continue to pursue our day-part initiatives, including support for our breakfast program, which became available in all Sonic drive-ins during the last year. These initiatives, combined with the outlook for a continued strong development program, its impact on franchising income, and our unique ascending royalty structure, put the fundamentals in place to deliver 15%-16% earnings per share growth in fiscal 2004.”

        For its first fiscal quarter ending November 30, 2003, Sonic estimates that diluted earnings per share will be in the range of $0.29 to $0.30 based on the following assumptions:

• Total revenue growth of 13% to 15% as a result of: 1% to 3% higher system-wide same-store sales; 40-45 new drive-in openings, including 35 to 40 by franchisees; and growth in franchising income resulting from new franchise drive-ins, as well as higher royalties due to the company’s unique ascending royalty rate;

• An increase in restaurant-level costs, as a percentage of sales, of 25 to 50 basis points resulting from slightly higher food and packaging costs, as well as higher labor costs associated with the company’s initiative to build its store-level management infrastructure;

• Continued leverage from the bottom part of the income statement, with corporate overhead expenses expected to grow in the range of 8% to 10% and an anticipated increase in depreciation and amortization of 12% to 14%; and

• Flat to slightly lower interest expense resulting from the use of the company’s cash flow to reduce debt; alternatively, the company may choose to repurchase stock (the company had $50.0 million authorized for that purpose at year’s end).
