Casey’s Counters Tough Gas Market with

Improved Store Sales

Ankeny, Iowa, December 7, 2004—Casey’s General Stores, Inc. (Nasdaq symbol CASY) today reported basic earnings of $0.22 per share for the second quarter of fiscal 2005 ended October 31, 2004, down from $0.32 a year ago. Earnings year to date were $0.54 compared with $0.60 the previous midyear. “Despite the challenging gasoline environment, we are pleased with our achievements in the second quarter, especially with the gains made inside our stores,” said Chairman and CEO Ronald M. Lamb.

Gasoline—Casey’s gasoline goal is to increase same-store gallons sold at least 2% with an average margin of at least 10.5 cents. “We gained ground on same-store gallons sold in the quarter. Rising wholesale prices, however, lowered our average margin to 9.7 cents from 11.9 cents for the same period a year ago,” Lamb explained. “The lower margin held our gasoline gross profit to $25.2 million, down from $30 million.” As of midyear, gallons sold increased to 522.9 million, the average margin was above goal at 10.8 cents, and gasoline gross profit was $56.3 million.

Grocery & Other Merchandise (G&OM)—The G&OM goal is to increase same-store sales 2.9% with an average margin over 32%. Year to date, total sales were up 5.5% to $384.2 million with an average margin of 31%, same-store sales increased 3.3%, and gross profit rose 2.8% to $119.3 million. Lamb stated, “We are responding to changes cigarette manufacturers made in their wholesale programs, and analysis of point-of-sale data is adding significantly to our success at managing merchandise effectively.”

Prepared Food & Fountain (PF&F)—The goal for PF&F is to increase same-store sales 6% with an average margin over 60%. For the year to date, total sales rose 11.7% to $105.9 million with an average margin of 59.6%, same-store sales climbed 7.4%, and gross profit was up 7.7% to $63.1 million. Lamb gave new menu and fountain offerings and better inventory control as reasons for greater profitability. “We’ve experienced exceptional growth the past six quarters,” Lamb added, “and we are confident there is more growth ahead.”

Point of Sale (POS)—The Company intends to have over 900 stores with full POS by fiscal year-end. At midyear, the total was 740. “Our accelerated installation rate will enable us to exceed this goal,” said Lamb. “We now are developing a platform for implementing the data warehouse and business intelligence software we tested in the first quarter. We believe the additional refinements in our data analysis processes gained from this initiative will enhance operational efficiencies.”

Operating Expenses—The Company’s goal for operating expenses is to hold the percentage increase to no more than the percentage increase in inside sales. Year to date, total inside sales were up 6.8% to $490.1 million while operating expenses were up 8.2% to $168 million. Total gross profit rose 3.5% to $240.2 million. “A substantial rise in the number of credit card transactions and higher credit card totals for gasoline led to a 30% increase in bank charges,” Lamb elaborated, “but overall we are managing our expenses well. Our ongoing priority is to increase gross profit.”

Expansion—The Company’s final goal is to acquire at least 43 stores and build 15 new stores to achieve 3.5% total store growth. As of October 31, Casey’s had constructed 5 new stores, completed 4 acquisitions, signed written agreements for another 25, and negotiated preliminary agreements for 5 more stores. “We anticipate closing the majority of our written agreements in the next quarter,” Lamb stated. “There continue to be ample acquisition opportunities, and we are aggressively pursuing them.”

At its December meeting, the Board of Directors declared a quarterly dividend of $0.04 per basic share. The dividend is payable February 15, 2005 to shareholders of record on February 1, 2005.
