First Business Financial Services in Madison plans to issue more stock.

Shareholders of First Business, parent company of First Business Bank, agreed at a special meeting Tuesday to increase the authorized common stock from the current 8 million shares to 25 million and to authorize up to 2.5 million shares of preferred stock, according to papers filed with the U.S. Securities and Exchange Commission.

President and chief executive Corey Chambas said there are no specific plans for the additional shares, but they would be needed if First Business decides to make an acquisition at some time or to apply for funds under the U.S. Treasury's Troubled Asset Relief Program. Chambas said bank officials have not decided if they would take TARP financing even if it were approved.
