Immunomedics Announces Third Quarter Fiscal 2007 Results

      MORRIS PLAINS, N.J., May 8 /PRNewswire-FirstCall/ -- Immunomedics, Inc.
(Nasdaq: IMMU), a biopharmaceutical company focused on developing monoclonal
antibodies to treat cancer and other serious diseases, today reported revenues
of $0.9 million and a net loss of $5.1 million, or $0.08 per share, for the
third quarter of fiscal year 2007, which ended March 31, 2007. This compares to
revenues of $1.3 million and a net loss of $5.7 million, or $0.10 per share, for
the same period last year. Revenues for the three-month period ended March 31,
2007 did not include any amortization of deferred revenues derived from the May
2006 agreement with UCB, due to the decision by UCB to begin new clinical trials
for the treatment of systemic lupus erythematosus ("SLE"). As a result of this
decision, Immunomedics has discontinued the amortization of the deferred revenue
until a determination can be made as to how the UCB decision will impact the
Company's obligations under the UCB agreement. The decrease in net loss for the
three-month period in 2007 was primarily due to higher interest income combined
with lower interest and operating expenses.

      For the first nine months of the 2007 fiscal year, the Company reported
revenues of $7.7 million and a net loss of $12.1 million, or $0.20 per share.
This compares to revenue of $2.2 million and a net loss of $23.1 million, or
$0.42 per share, for the same period last year. Recognition of deferred revenue
from the UCB agreement for the first six months of the 2007 fiscal year
contributed to the decrease in net loss for the nine-month period in 2007, as
well as increased sales of LeukoScan in Europe, and higher interest income. The
current period's results also benefited from reduced operating and interest
expenses.

      At March 31, 2007, the Company had $27.7 million in cash and marketable
securities. On May 7, 2007, the Company closed on its previously announced $24
million registered direct offering of common stock. After payment of fees and
expenses, the net proceeds to the Company are expected to be approximately $22.3
million.

      "We are pleased that our financial results for the third quarter of the
2007 fiscal year were in line with our expectations. Although we have recently
bolstered our cash position with a sale of our common stock, licensing remains
an important means for us to raise capital," commented Gerard G. Gorman, Senior
Vice President, Finance and Business Development, and Chief Financial Officer.
"We are committed to identifying a potential partner for the licensing of hA20
for all indications on a worldwide basis."

      About Immunomedics

      Immunomedics is a New Jersey-based biopharmaceutical company focused on
the development of monoclonal, antibody-based products for the targeted
treatment of cancer, autoimmune and other serious diseases. We have developed a
number of advanced proprietary technologies that allow us to create humanized
antibodies that can be used either alone in unlabeled or "naked" form, or
conjugated with radioactive isotopes, chemotherapeutics or toxins, in each case
to create highly targeted agents. Using these technologies, we have built a
pipeline of therapeutic product candidates that utilize several different
mechanisms of action. We have licensed our lead product candidate, epratuzumab,
to UCB, S.A. for the treatment of all autoimmune disease indications worldwide.
We have retained the rights for epratuzumab in oncology indications for which
UCB has been granted a buy-in option. UCB has development, manufacture and
commercialization rights, and is responsible for all clinical trials evaluating
epratuzumab for the treatment of patients with moderate and severe lupus. At
present, there is no cure for lupus and no new lupus drug has been approved in
the U.S. in the last 40 years. The Company is conducting clinical trials with
hA20 in patients with non-Hodgkin's lymphoma, epratuzumab as a potential
therapeutic for patients with lymphoma and leukemia, 90Y-epratuzumab for the
therapy of patients with lymphoma, 90Y-hPAM4 for pancreas cancer therapy and
hCD74 as a therapy for patients with multiple myeloma. We believe that our
portfolio of intellectual property, which includes approximately 108 patents
issued in the United States, and more than 250 other issued patents worldwide,
protects our product candidates and technologies. We also have a majority
ownership in IBC Pharmaceuticals, Inc., which is developing a novel Dock and
Lock (DNL) methodology, and a new method of delivering imaging and therapeutic
agents selectively to disease, especially different solid cancers (colorectal,
lung, pancreas, etc.), by proprietary, antibody-based, pretargeting methods. For

form a part of this press release.
