Casey’s Opens 28 Stores in the Quarter, Positioned Well for Future Growth

Ankeny, IA, March 11, 2013—Casey’s General Stores, Inc. (Nasdaq symbol CASY) today reported $0.40 in diluted earnings per share for the third quarter of fiscal 2013 ended January 31, 2013 compared to $0.43 for the same period a year ago. Year-to-date diluted earnings per share was $2.26 versus $2.44 for the same period last year. “The quarter was adversely impacted by a challenging cigarette environment,” said Chairman and CEO Robert J. Myers. “However we did experience improved cigarette sales throughout the third quarter and continue to drive prepared food sales with several operational initiatives being implemented within our store base.”

Gasoline—The Company’s annual goal is to increase same-store gallons sold 1% with an average margin of 14.0 cents per gallon. For the third quarter, same-store gallons sold were up 0.6% with an average margin of 13.8 cents per gallon. “The retail price of fuel was in-line with the prior year’s third quarter, which helped improve same-store gallons sold,” said Myers. For the first nine months of the fiscal year, total gallons sold were up 3.6% with an average margin of 14.6 cents per gallon. Year-to-date same-store gallons sold were flat compared to prior year.

Grocery and Other Merchandise—Casey’s annual goal is to increase same-store sales 6.2% with an average margin of 32.7%. For the quarter, same-store sales were up 3.2% with an average margin of 31.7%. “Cigarette sales stabilized in the third quarter due to retail price adjustments made throughout the fiscal year,” stated Myers. “Although these adjustments adversely impacted our overall margin, the margin decline was partially offset by a more favorable product mix within the grocery and other merchandise category.” For the nine months ended January 31, 2013, same-store sales were up 1.3% with an average margin of 32.9%. Total sales for the year are up 4.3% and gross profit increased 6.2% to $354.7 million.

Prepared Food and Fountain—The goal for fiscal 2013 is to increase same-store sales 11% with an average margin of 61.1%. For the quarter, same-store sales were up 11.6% with an average margin of 60.6%. “An increase in cheese prices coupled with some other input cost increases pulled the margin back this quarter,” said Myers. “Fortunately same-store sales continue to perform well due in part to expanded 24-hour operations, pizza delivery, and major remodels.” For the year, same-store sales were up 10.2% with an average margin of 62.2%. Year-to-date, total sales were up 14.8% and gross profit rose 17.7% to $265.1 million.

Operating Expenses—Year to date, operating expenses increased 11.1% to $569.3 million. For the third quarter, operating expenses were up 12.2%. Included in the third quarter results was a $1.1 million impairment charge stemming from the planned closure of several stores in a recent acquisition. “The majority of the operating expense increase for both the quarter and year were from newly built, acquired and replaced stores over the past two fiscal years, along with the continued roll-out of 24-hour stores, pizza delivery, and major remodels,” stated Myers. Store-level operating expenses for locations not impacted by the initiatives were up approximately 3.8% for the quarter and 4% for the first nine months.

Expansion—The annual goal is to increase the total number of stores 4-6%. Through the first nine months of the fiscal year, the Company opened 18 newly constructed stores and 21 acquired stores. The Company also replaced 22 stores. “We will continue to update and improve our existing store base while maintaining our steady growth of new and acquired stores,” said Myers. Casey’s currently has 21 new stores and 12 replacement stores under construction, as well as 10 stores under written agreement to acquire. The Company also has 50 new sites and 25 replacement sites under contract to purchase.

Dividend—At its March meeting, the Board of Directors declared a quarterly dividend of $0.165 per share. The dividend is payable May 15, 2013 to shareholders of record on May 1, 2013.
