(Nasdaq: ENZN) announced today that it has revised its revenue guidance for the fiscal year (FY) ending June 30, 2005 based on reduced expectations for North American sales of ABELCET(R) (amphotericin B lipid complex injection), the Company's antifungal product. The revised expectations reflect weaker-than-anticipated demand for ABELCET and increasingly competitive market conditions. Enzon currently expects North American sales of ABELCET of $55 million to $60 million for the FY ending June 30, 2005, as compared to the Company's prior guidance of $69 million to $73 million. As a result of the revised ABELCET guidance, the Company now expects combined product sales for its four internally marketed products of $100 million to $115 million for the FY ending June 30, 2005, as compared to Enzon's prior guidance of $110 to $125 million.
