                      IMMUNOMEDICS ANNOUNCES SECOND QUARTER
                               FISCAL 2006 RESULTS

Morris Plains, NJ, February 14, 2006 - Immunomedics, Inc. (Nasdaq: IMMU), a
biopharmaceutical company focused on developing monoclonal antibodies, today
reported revenues of $0.5 million and a net loss of $8.8 million, or $0.16 per
share, for the second quarter of fiscal year 2006, which ended December 31,
2005. This compares to revenues of $1.0 million and a net loss of $6.4 million,
or $0.12 per share, for the same period last year. For the first half of the
2006 fiscal year, the Company reported revenues of $0.9 million and a net loss
of $17.4 million, or $0.32 per share. This compares to revenue of $2.1 million
and a net loss of $10.6 million, or $0.20 per share, for the same period last
year. The increase in net loss for the three-month period was primarily due to
increased interest expense from the Company's outstanding 5% senior convertible
notes issued in April 2005, and reduced sales revenue from diagnostic imaging
products. The increased interest expense includes the amortization of the debt
issuance costs and debt discounts, and a $1.0 million charge resulting from the
change in the market value of the derivative interest liability associated with
the make-whole interest provision relating to the 5% senior convertible notes.
The increase in the net loss for the six-month period was due to these factors
as well as higher levels of R&D spending, primarily to support the Phase III
trials evaluating epratuzumab in patients with lupus. Additionally, the 2004
results included a net litigation settlement gain of $1.2 million.

During this second quarter, the Company received $0.5 million in tax benefits
through the New Jersey Technology Tax Certificate Transfer Program. At December
31, 2005, the Company had $14.6 million in cash and marketable securities, in
addition to $3.2 million of restricted securities that collateralize the New
Jersey Economic Development Authority financing completed in May 2003 for the
construction of the Company's expanded manufacturing facilities.

"The implementation of our cost savings program during this quarter has allowed
us to maintain our operating loss at a level similar to that of the same period
last year. To further conserve capital for our research and development
programs, we have deferred certain executive's salaries, the executive bonus
program and continue to evaluate the deferral of non-essential expenditures. At
the same time we are working diligently on establishing a global corporate
partner for the further clinical development and commercialization of
epratuzumab," commented Gerard G. Gorman, Vice President, Finance, and Chief
Financial Officer.

As reported previously during the second quarter of fiscal year 2006, other
developments of note were as follows:

o     The Company provided details of the ALLEVIATE trial designs, testing
      epratuzumab in patients with lupus, at the Lazard Capital Markets Annual
      Life Sciences Conference.

o     The Company presented updated clinical results for epratuzumab in
      Sjogren's syndrome at the 2005 annual scientific meeting of American
      College of Rheumatology/Association of Rheumatology Health Professionals.

o     At the 47th Annual Meeting of American Society of Hematology, the Company
      reported preclinical results on a new therapeutic, advances in lymphoma
      therapy with a humanized anti-CD20 antibody, and results with the
      combination of epratuzumab and rituximab in patients with lymphoma.

o     The Company presented at the Rodman & Renshaw Techvest 7th Annual
      Healthcare Conference during which a corporate overview was provided.

o     The Company published an article on a new diagnostic assay for pancreatic
      cancer in the Journal of Clinical Oncology.

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. Our lead product candidate, epratuzumab, is currently in two pivotal
Phase III trials for the treatment of patients with moderate and severe lupus
(ALLEVIATE A and B). 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. We believe that our
portfolio of intellectual property, which includes approximately 90 patents
issued in the United States, and more than 250 other issued patents worldwide,
protects our product candidates and technologies. Visit our web site at
