Casey’s Continues Strong Performance in the Second Quarter

Ankeny, Iowa, December 6, 2005—Casey’s General Stores, Inc. (Nasdaq symbol CASY) today reported $0.44 in earnings per share from continuing operations for the second quarter of fiscal 2006 ended October 31, 2005. The earnings were up 91.3% from $0.23 for the same quarter a year ago. Earnings from continuing operations year to date were $0.89 per share compared with $0.55 at the previous midyear. Chairman and CEO Ronald M. Lamb stated, “At the six-month mark all three of our business categories were exceeding annual goals for sales and margins, giving the Company a 27.9% increase in total sales and a substantial gross profit gain of 19.9%.”

Gasoline—Casey’s annual goal is to increase same-store gasoline gallons sold 2% with an average margin of 10.5 cents per gallon. On a same-store basis, gallons sold in the second quarter were up 4.3% with an average margin of 13.9 cents; for the year to date, they were up 6% with an average margin of 12.8 cents. Gross profit for the six months rose 30.1% to $72.1 million. Lamb explained that extraordinary market conditions existed during the second quarter: “Hurricane activity caused considerable volatility in wholesale gasoline costs. We adhered to our consistent policy of pricing with the competition and made gains in same-store sales and margin.”

Grocery & Other Merchandise—The annual goal is to increase same-store sales 3% with an average margin of 31.5%. The same-store sales increase was 4.5% for the quarter with an average margin of 33.2% and 6% for the year to date with an average margin of 32.6%. The six-month gross profit grew 14.7% to $135.1 million. “Our strategic focus on aligning product mix with customer demand served us well,” Lamb said, “and the lottery has become a destination item drawing additional customers to our stores.”

Prepared Food & Fountain—The annual goal is to increase same-store sales 5.5% with an average margin of 60.5%. For the quarter, same-store sales were up 4.5% with an average margin of 64.6%. For the six months, same-store sales were up 5.9% with an average margin of 64.3%. The year-to-date gross profit was $74.3 million, a 19% increase. Lamb gave this assessment: “We drove sales and margins by matching menu items to customer preferences, introducing new products, and controlling stales.”

Operating Expenses—It is the annual goal to hold the percentage increase in operating expenses to less than the percentage increase in gross profit. Operating expenses year to date were up 11.1% to $183 million. Lamb stated, “Thanks to our sound management strategies, the 19.9% increase in gross profit to $284.4 million far surpassed the percentage increase in expenses.”

Expansion—The Company is in the final stages of completing the Gas `N Shop purchase agreement. “We’re excited about the Gas ‘N Shop additions,” stated Lamb, “and we’ll begin re-branding the sites to Casey’s General Stores as soon as the transaction is closed. Our team has also targeted numerous individual competitor stores and other regional chains as potential future acquisitions.” The Company’s annual goal is to acquire 30 stores (in addition to the Gas ‘N Shop acquisition) and build 10 new stores. At October 31, 2005, Casey’s had built 7 stores, acquired 14 stores, and signed written agreements to acquire 5 more.

At its November 30, 2005 meeting, the Board of Directors declared a quarterly dividend of $0.045 per share. The dividend is payable February 15, 2006 to shareholders of record on February 1, 2006.
