(Nasdaq: ATSI) developer, manufacturer and marketer of state-of-the-art cardiac surgery products and services, today announced a definitive agreement under which ATS will acquire all the outstanding shares of privately-held 3F Therapeutics in a stock for stock transaction. Based in Irvine, California, 3F Therapeutics is an early stage medical device company at the forefront of the emerging field of minimally invasive beating heart tissue valve replacement. The acquisition of 3F Therapeutics is viewed as a major step in executing ATS Medical's longstanding vision of obtaining a leadership position in all segments of the cardiac surgery market. Under the terms of the definitive agreement, ATS Medical will acquire 3F Therapeutics by issuing nine million shares of ATS common stock to 3F shareholders. In addition, 3F shareholders will be issued up to an additional 10 million shares of ATS stock upon the achievement of milestones. ATS Medical will assume the 3F balance sheet that includes an estimated $10 million in cash as of December 1, 2005, to fund future development. It is anticipated that the proposed acquisition will be completed in the second quarter of 2006. The proposed acquisition is subject to various terms and conditions, including ATS shareholder approval. Piper Jaffray & Co. has served as financial advisor to ATS and UBS Securities LLC acted as financial advisor to 3F in connection with the transaction. "The joining of ATS Medical and 3F Therapeutics firmly establishes ATS Medical as a leader and creates the most advanced heart valve therapy product portfolio in the world," said Michael Dale, Chairman, President and CEO of ATS Medical. "We are tremendously excited about how this transaction strengthens our Company's position in the heart valve therapy space and further heightens our growth potential in the cardiac surgery market. It is a significant milestone toward achieving our long-term goal of building ATS Medical's annual revenue to a level in excess of $100 million." 3F Therapeutics was founded in 1998 with a focus similar to that of ATS Medical, on serving the needs of the cardiac surgeon. 3F Therapeutics' fundamentally unique heart valve product design concepts are intended to improve on the performance of existing heart valves by mimicking natural valves. With the belief that there is not a single solution for each heart valve implant, 3F Therapeutics has worked toward offering cardiac surgeons several biological tissue heart valve options from which to choose. Its first product, the 3F Aortic Bioprosthesis(TM), has been commercially released in Europe and the U.S. FDA submission process is underway. According to Walter A. Cuevas, President and CEO of 3F Therapeutics, "The 3F Therapeutics product pipeline addresses all segments of the existing $600 million tissue valve market and our development program and intellectual property support the creation of a new off pump, beating heart valve replacement segment in the years to come." Cuevas continued, "We believe ATS and 3F together can ultimately satisfy all unmet patient and cardiac surgeon needs in the heart valve therapy space." ATS expects to continue 3F Therapeutics' operating activities at the Irvine, California facility. Currently, ATS Medical has approximately 31 million common shares outstanding. On Monday, January 23, the company announced fourth quarter and full year 2005 revenue of $9.9 million and $34.6 million respectively which was in-line with the guidance management previously provided.
