Exhibit 99.1 Immunomedics Announces First Quarter Fiscal 2004 Results MORRIS PLAINS, N.J., Nov. 13 /PRNewswire-FirstCall/ -- Immunomedics, Inc. (Nasdaq: IMMU) today reported revenues of $1.2 million and a net loss of $5.2 million, or $0.10 per share, for the first quarter of fiscal year 2004, which ended September 30, 2003. This compares to revenues of $3.2 million and a net loss of $2.9 million, or $0.06 per share, for the same period last year. The decline in revenues resulted primarily from the fact that the Company recognized its final portion of the $18.0 million up-front licensing payment from Amgen in the third quarter 2003. At September 30, 2003, the Company had $25.8 million in cash and liquid securities, including $6.1 million of restricted cash associated with the EDA financing completed for the manufacturing facilities. Mr. Gerard G. Gorman, the Company's Vice President, Finance, and Chief Financial Officer, commented: "We are pleased to report that the results for the first fiscal quarter were in line with our expectations. We will continue to assess opportunities to raise additional capital through the further licensing of our products and technologies, the sale of debt and/or equity securities, or some combination of the foregoing as they arise." Other developments of note during the first fiscal quarter of 2004 were as follows: * The Company completed construction of its large-scale antibody manufacturing facility at its headquarters in Morris Plains, New Jersey. * The Company announced that near-term clinical development plans now include the evaluation of two proprietary cancer therapeutic antibodies, humanized CD22 (IMMU-103, epratuzumab) and humanized CD20 (IMMU-106) in the new indication of autoimmune disease therapy. * Programs have been implemented for the near-term commencement of clinical trials with IMMU-106 also in patients with non-Hodgkin's lymphoma, and the development of a new product candidate, humanized PAM4 (IMMU-107), for the therapy of pancreatic cancer. * In September, the Company presented at the Bear Stearns 16th Annual Healthcare Conference and at the UBS Global Life Sciences Conference. "Our investments in research and development and the addition of key personnel to our clinical research and operations departments continue to yield important advances for our Company, with the preclinical and clinical evaluation of new antibodies and the expansion of existing product candidates into new indications," commented Company President and Chief Executive Officer, Cynthia L. Sullivan. "The continued growth of our product pipeline and progress of our clinical agents, together with the completion of our large-scale production facilities, will further facilitate our aggressive development plans for our therapeutic product pipeline," Ms. Sullivan remarked.
