This announcement was made by Jerry A. Grundhofer, president and chief executive officer of Firstar Corporation, following the regularly scheduled board of directors meeting. Grundhofer commented, "Firstar's three-for-one stock split should make the price of our stock more accessible and desirable to a broader range of investors. We anticipate that the stock split will increase the liquidity and marketability of our stock and increase Firstar's total shareholder base. The share repurchase authorization gives the corporation flexibility to maintain our strong capital position and return any excess capital to shareholders. As a result of the stock split, shareholders of record on March 31, 1999 will receive an additional two shares of Firstar common stock for each share they currently own. The payable date for the stock split is April 15, 1999. Following the stock split, the number of outstanding common shares of Firstar stock will triple to approximately 655 million shares with the company's stock price and per share earnings reflecting the expanded number of shares. Firstar Corporation's last stock split was announced December 10, 1996, when the company declared a three-for-one split. Additionally, shareholders of record on March 31, 1999 will be paid a regular quarterly dividend of $0.30 per common share on April 15, 1999 based on pre- split shares. Firstar Corporation anticipates that the repurchases for the stock repurchase plan will be made periodically throughout the next two years. The common shares may be repurchased in the open market or in privately negotiated transactions.
