MINNEAPOLIS -- American Medical Systems Holdings, Inc. (NASDAQ:AMMD) announced today that its Board of Directors has approved a two-for-one split of the company's common stock in the form of a 100% percent stock dividend. The stock split is subject to shareholder approval of an increase in the number of authorized shares of common stock from 75 million to 200 million. American Medical Systems plans to hold a special meeting of stockholders on March 3, 2005 to approve the increase. If the stockholders approve the increase, all stockholders of record on March 14, 2005 will receive one additional share for each share then held. Distribution of shares is scheduled to be made on or about March 21, 2005.

American Medical Systems also reported preliminary record sales of $60 million for the fourth quarter of 2004, a 27 percent increase over sales of $47.2 million in the comparable quarter of 2003. Preliminary sales in the full year 2004 were $208.8 million, up 24 percent from sales of $168.3 million in 2003. The Company anticipates full year earnings, excluding any one-time items, to be in line with the previously guided range of $0.99 to $1.01 per share.

Martin J. Emerson, President and recently named CEO of American Medical Systems, noted, "We are pleased that the sales momentum of the first three quarters of 2004 was sustained through the fourth quarter. In addition to strong core business growth, sales from our recent TherMatrx acquisition also met our expectations. I look forward to the challenge of continuing the company's strong record of growth in 2005 and beyond."

Douglas W. Kohrs, Chairman of American Medical Systems, commented, "The decision to split the company's stock represents a vote of confidence by our Board of Directors and, along with our financial performance, evidences our success during the past five years in transforming AMS from essentially a two- product company to a leader in providing an array of solutions for the pelvic health needs of men and women."
