Exhibit 99.1 IMMUNOMEDICS REPORTS FISCAL THIRD QUARTER 2003 RESULTS Morris Plains, NJ, May 8, 2003 - Immunomedics, Inc. (Nasdaq: IMMU) today reported revenues of $5.6 million and net income of $453,000, or $0.01 per share, for the third quarter of fiscal year 2003 which ended March 31, 2003. This compares to revenues of $3.3 million and a net loss of $296,000, or $0.01 per share, for the same period last year. The net income was mainly due to the Company's recognition of previously deferred payments of supply fees from its licensee, Amgen, in the amount of $3.8 million. Income recognition had been deferred until the Company was able to satisfy certain supply obligations that were satisfied in the third quarter. For the first nine months of fiscal year 2003, Immunomedics reported revenues of $12.0 million and a net loss of $4.2 million, or $0.08 per share. This compares to revenues of $10.0 million and a net loss of $1.1 million, or $0.02 per share, for the same period last year. 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 third fiscal quarter were in line with our expectations. At March 31, 2003 we had $28.4 million in cash and liquid securities. The construction of our new manufacturing facility is nearing completion and we intend to refinance the construction costs of $6.3 million with a bank credit facility in the near future to further improve our cash position." Ms. Cynthia L. Sullivan, President and Chief Executive Officer of Immunomedics, added: "Our expanded manufacturing facility will provide the production capacity needed to develop and support our extensive product pipeline. Phase I clinical trials with our humanized alpha-fetoprotein antibody for evaluation in patients with primary liver cancer are now beginning, and we plan to begin additional clinical trials with another therapeutic product candidate before the end of the calendar year. Other developments of note since the start of the third quarter are as follows: o The Company and Amgen announced their continued focus on the development of Immunomedics' proprietary compound, epratuzumab, with particular emphasis on its use in combination with Rituximab. "We are pleased with the focus of this development program to generate additional supportive data for combination therapy and also pleased with Amgen's work with cooperative study groups of the National Cancer Institute to evaluate the benefits of the antibody combination with chemotherapy in aggressive NHL patients," Ms. Sullivan added. o The Company announced that an article published in The Journal of Nuclear Medicine (Vol. 44, No. 1, January 2003) described an improved method of linking yttrium-90 (Y-90) to its antibody, epratuzumab in clinical trials for therapy of NHL. "This improved conjugation method could potentially reduce the side effect of hematological toxicity and should enable higher doses of Y-90 to be administered safely," Ms. Sullivan remarked. o The Company met with investors and analysts at the Raymond James Equity Conference. "Our investments in research and development continue to yield important advances for our Company with the discovery of new antibodies. The continued growth of our research and development capabilities in 2003, together with the completion of our expanded production facilities by year-end, will further facilitate our aggressive development plans for our therapeutic product pipeline," Ms. Sullivan remarked. In a positive development for the Company's majority owned subsidiary, IBC Pharmaceuticals, Inc., two distinguished scientists, Henry N. Wagner, Jr., M. D., and John B. Landis, Ph.D., were elected to the IBC Board of Directors. "Dr. Wagner is, in my view, the best known and most respected nuclear medicine physician-scientist and advocate on an international basis, and Dr. Landis is an exceptional chemist and research executive with a proven track record in the pharmaceutical industry," commented Dr. David M. Goldenberg, founder and Chairman of the Board of Directors of IBC Pharmaceuticals and also of Immunomedics.
