            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.
