Vote the WHITE Proxy Card Today

Welcome to our website, SupportCaseys.com. You can find here information pertaining to Casey’s General Stores, Inc. (“Casey’s”) and our annual meeting of shareholders to be held on September 23, 2010. The votes of Casey’s shareholders are very important at this pivotal time in the Company’s history. As you may know, Alimentation Couche-Tard Inc. is attempting to replace Casey’s Board with its hand-picked slate of nominees. We believe Couche-Tard’s nomination of an opposition slate is solely an attempt by Couche-Tard to advance its proposal for a business combination with Casey’s. Under the leadership of our current Board, Casey’s is already creating far greater value for shareholders than is reflected in Couche-Tard’s offer.

We urge all Casey’s shareholders to vote for Casey’s Board nominees using the WHITE proxy card that they have received from Casey’s. You can find voting instructions, biographies of our directors, relevant letters to shareholders, and other useful information on this website. We encourage you to read all the materials carefully and sign-up below to receive updates.

Thank you for your support.

About Casey’s

Casey’s General Stores, Inc. and our wholly owned subsidiaries operate convenience stores under the name “Casey’s General Store”, “HandiMart” and “Just Diesel” in nine Midwestern states, primarily Iowa, Missouri, and Illinois. Our stores carry a broad selection of food (including freshly prepared foods such as pizza, donuts, and sandwiches), beverages, tobacco products, health and beauty aids, automotive products, and other nonfood items. In addition, all of our stores offer gasoline for sale on a self-service basis.

Casey’s has 1,531 stores, as of June 30, 2010. Approximately 61% of all our stores are located in areas with populations of fewer than 5,000 persons, while approximately 14% of our stores are located in communities with populations exceeding 20,000 persons. We seek to meet the needs of residents of smaller towns by combining features of both general store and convenience store operations. Smaller communities often are not served by national-chain convenience stores. We have succeeded at operating Casey’s General Stores in smaller towns by offering, at competitive prices, a broader selection of products than does a typical convenience store. We have also succeeded in meeting the needs of residents in larger communities with these offerings. We currently own most of our real estate, including the Casey’s Distribution Center and Corporate Headquarters facility.

You can find more information about Casey’s at www.caseys.com.

Our Board

Casey’s Board of Directors consists of seven independent members out of eight total directors. The Board has an exceptional track record of creating value for Casey’s shareholders. Under our Board’s leadership, Casey’s has:

Consistently outperformed its peer group’s stock performance and the broader market. In the three year period prior to the public announcement of the Couche-Tard offer, Casey’s stock increased 24% while the convenience store peer group experienced an average decrease of 46% and the S&P 500 decreased 18%;

Continued to have the highest inside-same stores sales margins in the industry, which have enabled us to achieve double-digit annual earnings per share (EPS) growth over the five fiscal years ended April 30, 2010;

Increased our dividend at a compounded annual growth rate of approximately 17.3% over the past five years, and we increased our dividend again at the start of fiscal 2011. The Company’s dividend payout ratio for the fiscal year ended April 30, 2010 was 15%, the highest ratio among industry peers; and,

Achieved positive inside same-store sales growth for 26 consecutive quarters, averaging 5.9% for the five fiscal years ended April 30, 2010, versus the convenience store peer average of 3.5% for the comparable fiscal period.

We urge shareholders to vote the WHITE card “FOR” the Casey’s Board of Directors.

Forward-looking statements represent our expectations or beliefs concerning future events that may not prove to be accurate. The words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “project” and similar expressions are used to identify forward-looking statements. We caution you that these statements are further qualified by important factors that could cause actual results to differ materially from those in the forward-looking statements, including the risk that our cash balances and cash generated from operations and financing activities will not be sufficient for our future liquidity and capital resource needs, competition in the industry in which we operate, changes in the price or supply of gasoline, tax increases or other changes in the price of or demand for tobacco products, potential liabilities and expenditures related to compliance with environmental and other laws and regulations, the seasonality of demand patterns, weather conditions, future actions by Couche-Tard in connection with its unsolicited tender offer to acquire Casey’s, the risk that disruptions or uncertainty from Couche-Tard’s unsolicited tender offer will divert management’s time and harm Casey’s relationships with our customers, employees and suppliers; the increased indebtedness that the Company has incurred to purchase shares of our common stock in our self tender offer; the price at which we ultimately determine to purchase shares of our common stock in our self tender offer and the number of shares tendered in such offer; the price and time at which we may make any additional repurchases of our common stock following completion of our self tender offer as well as the number of shares acquired in such repurchases and the terms, timing, cost and interest rate on any indebtedness incurred to fund such repurchases; and the other risks and uncertainties included from time to time in our filings with the SEC. We further caution you that other factors we have not identified may in the future prove to be important in affecting our business and results of operations. We ask you not to place undue reliance on any forward-looking statements because they speak only of our views as of the statement dates. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
