Casey’s Increases Earnings over 50%

Ankeny, Iowa, September 8, 2009—Casey’s General Stores, Inc. (Nasdaq symbol CASY) today reported earnings per share of $0.87 for the first quarter of fiscal 2010 ended July 31, 2009. For the same quarter a year ago, earnings per share were $0.57. “Strong gas margins and enhanced profitability inside the stores were the primary reasons for the record quarter,” said President and CEO Robert J. Myers. “Lower retail fuel prices also brought about significant relief in our operating expenses.”

Gasoline—Casey’s annual goal is to increase same-store gasoline gallons sold 2% with an average margin of 11 cents per gallon. The quarter’s same-store gallons sold were up 3.2% with an average margin of 15.7 cents per gallon. The average retail price per gallon was $2.35, down 38% from the same period a year ago. “We believe lower retail prices were a factor in exceeding our same-store sales goal,” stated Myers. “Our gasoline margin continues to benefit from a more responsive pricing environment.” Total gallons sold rose to 335.8 million from 318.2 million; gross profit was $52.7 million compared with $49.6 million.

Grocery & Other Merchandise—The Company’s goal is to increase same-store sales 8.9% with an average margin of 33.9%. Same-store sales for the quarter were up 6.4%, with an average margin of 34.3% compared to 34% last year. Gross profit rose 9.2% to $102 million. “We are pleased with this category’s performance despite experiencing one of the coldest summers on record, which particularly affected beverage and beer sales,” said Myers. “The gain in gross profit was primarily due to higher cigarette revenue attributable to the federal excise tax increase, along with an improved pack-versus-carton sales ratio.” Total sales were up 8.4% to $297.4 million.

Prepared Food & Fountain—The goal is to increase same-store sales 7.5% with an average margin of 62%. Same-store sales for the quarter were up 6.6% and the average margin was 63.8%, up approximately 330 basis points from the prior year. “Lower cheese costs, which we have locked in through October, helped increase total gross profit in this category over 17% from the same period a year ago,” Myers stated. “We expanded our coffee and fountain offerings and continue to roll out our made-to-order sub sandwich program.” Total sales for the category increased 11.1% to $95.2 million.

Operating Expenses—For the quarter, operating expenses declined 0.3% to $132.4 million. “Credit card fees and transportation costs combined were down almost $5 million compared to the first quarter a year ago.” said Myers. “We are encouraged by the great start to fiscal 2010 and will remain diligent in our efforts to control expenses throughout the year.”

Expansion—The goal for fiscal 2010 is to increase the total number of Casey’s stores 4%. By the end of the first quarter, the Company opened 5 newly constructed stores and replaced an additional 5 stores. There were no acquired stores opened during the quarter. “We have now incorporated the new store design in 61 locations, with 8 new sites and 13 replacement sites currently under construction,” said Myers.

Dividend—At its September meeting, the Board of Directors declared a quarterly dividend of $0.085 per share, reflecting the increase approved in June. The dividend is payable November 16, 2009 to shareholders of record on November 2, 2009.
