Casey’s Reports Record Year

Ankeny, Iowa, June 13, 2006—Casey’s General Stores, Inc. (Nasdaq symbol CASY) today reported earnings for the fourth quarter and the fiscal year ended April 30, 2006. Chairman and CEO Ronald M. Lamb announced, “We had a very solid quarter, earning $0.22 per share from continuing operations. For the year, we reached an all-time high of $1.25 per share. Casey’s annual sales were up 25.4%, and gross profit rose 15.2%.

Gasoline—The Company’s annual goal was to increase same-store gasoline gallons sold 2% with an average margin of 10.5 cents per gallon. “The category’s results surpassed our expectations for the year,” said Lamb. Same-store gallons sold were up 4.4% for the twelve months and 0.5% for the quarter. Lamb added, “Our average margin for fiscal 2006 was 11.5 cents per gallon, reflecting the market volatility that affected the entire industry.” The average margin for the quarter was 10.6 cents per gallon.

Grocery & Other Merchandise—The annual goal was to increase same-store sales 3% with an average margin of 31.5%. “We outperformed the sales and margin goal for the year by capitalizing on increased store traffic brought in by the lottery and enhancing our point-of-sale technology,” Lamb explained. Same-store sales were up 5.7% with an average margin of 31.9% for the twelve months. For the quarter, same-store sales were up 4.2% with an average margin of 31.3%.

Prepared Food & Fountain—The annual goal was to increase same-store sales 5.5% with an average margin of 60.5%. Lamb said, “This category was outstanding. We increased same-store sales 7.4% for the year and achieved an average margin of 63%. Same-store sales for the quarter also were up 7.4%, and the margin was 60.9%.” Lamb credited introducing profitable new products and using POS data to align menu items with customer demand and to manage inventory for the excellent results. “Expanding our fountain selections should add to our success in fiscal 2007,” Lamb commented.

Operating Expenses—Casey’s annual goal was to hold the percentage increase in operating expenses to less than the percentage increase in gross profit. Lamb said, “The goal was challenging every quarter all year long as bank fees continually increased along with the retail price of gasoline, but our strategies for growing gross profit worked extremely well.” Operating expenses for the year were up 10.6% while gross profit grew 15.2%. For the quarter, operating expenses increased 8.8% and gross profit was up 11.4%.

Expansion—The Company’s annual goal was to acquire 30 stores (in addition to the Gas ‘N Shop acquisition) and to build 10 new stores. “We actually built 15 stores,” Lamb stated, “because there were good opportunities in areas where there weren’t attractive potential acquisitions. We acquired 49 stores from Gas ‘N Shop and closed 10 of them that were in direct competition with our own stores in nearby locations. We acquired an additional 18 stores and at April 30 had written agreements for 6 more stores.” The Company completed expansion of its distribution center, gaining the capacity to serve at least 1,000 more stores.

Fiscal 2007 Goals—Lamb presented Casey’s goals for the new fiscal year:

• Increase same-store gasoline gallons sold 2% with an average margin of 10.8 cents per gallon.

• Increase same-store grocery & other merchandise sales 3.9% with an average margin of 32.2%.

• Increase same-store prepared food & fountain sales 7.9% with an average margin of 63.4%.

• Hold the percentage increase in operating expenses to less than the percentage increase in gross profit.

• Acquire 50 stores and build 10 new stores.

Dividend—At its June meeting, the Board of Directors increased the Company’s quarterly dividend to $0.05 per share. The dividend is payable on August 15, 2006 to shareholders of record on August 1, 2006.
