PART I

|------- | --------

Introduction

Immunomedics is a New Jersey-based biopharmaceutical company primarily 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, cytokines 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 also been one of the first companies to test antibody combinations as a possibly improved method of cancer therapy, and as a result have also embarked on the development of bispecific (bifunctional) monoclonal
antibodies targeting two distinct antigens on the same cancer cells.

We have exclusively licensed our product candidate,
epratuzumab, to UCB S.A., or UCB, for the treatment of all autoimmune disease indications worldwide. Epratuzumabs most advanced clinical testing is for the treatment of systemic lupus erythematosus, or SLE (lupus), and in non-Hodgkins
lymphoma, or NHL. At present, there is no cure for lupus and no new lupus drug had been approved in the U.S. in over 50 years until the recent approval of belimumab. We have retained rights to epratuzumab in oncology indications, subject to
UCBs buy-in option, and are advancing trials in lymphoma and in childhood acute lymphoblastic leukemia, or ALL, in cooperation with study groups in the U.S. and Europe. In addition, we have exclusively licensed our product candidate,
veltuzumab, in the subcutaneous formulation, to Nycomed GmbH, or Nycomed, for the treatment of all non-cancer indications worldwide. We have retained the rights to develop, manufacture and commercialize veltuzumab in the field of oncology.

During the last fiscal year, we have completed a clinical trial evaluating milatuzumab, our anti-CD74 antibody, as a therapy
for patients with multiple myeloma, or MM, and we have initiated a National Cancer Institute or NCI grant-supported study combining unlabeled veltuzumab with yttrium-90, or Y-90 labeled epratuzumab tetraxetan in patients with diffuse large B-cell
lymphoma, the aggressive form of NHL. We are also conducting a Phase Ib/II clinical trial of Y-90 clivatuzumab tetraxetan (hPAM4) combined with gemcitabine for treating patients with newly diagnosed advanced pancreatic cancer and a
dose-escalation study of, milatuzumab, conjugated with the potent chemotherapeutic, doxorubicin, in patients with MM. Milatuzumab-doxorubicin is the first product candidate from our antibody-drug conjugate, or ADC, program to have entered into human
testing. In addition, milatuzumab, as a single unconjugated antibody, is being evaluated as a therapy for patients with chronic lymphocytic leukemia, or CLL, and in combination with veltuzumab in NHL patients. In the first half of fiscal 2012, we
plan to begin a new study examining the safety and tolerability of our second ADC, labetuzumab-SN-38, in patients with colorectal cancer.

Our foremost clinical goals for fiscal year 2012 are the following:



| | 1. | Complete Phase Ib/II trial of Y-90 clivatuzumab tetraxetan + gemcitabine in advanced, inoperable, untreated pancreatic cancer;
| | -- | ------------------------------------------------------------------------------------------------------------------------------



| | 2. | Complete protocol design for 2 Phase III registration trials of Y-90 clivatuzumab tetraxetan + gemcitabine in patients with pancreatic cancer for a planned trial launch
in the second half of fiscal year 2012;
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Continue Phase I trial of doxorubicin-milatuzumab in MM patients;
| | -- | -----------------------------------------------------------------



| | 4. | Enroll patients with colorectal cancer into the Phase I trial of labetuzumab-SN-38, and launch a Phase III registration trial of veltuzumab in NHL if funding can be
secured.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We also have a majority ownership in IBC Pharmaceuticals, Inc., or IBC, which is developing a novel
Dock-and-Lock methodology, or DNL, with us for making fusion proteins and multifunctional antibodies, as



1



---

well as a new method of delivering imaging and therapeutic agents selectively to disease, especially different solid cancers (colorectal, lung, pancreas, breast, etc.), by proprietary,
antibody-based, pretargeting methods. The first DNL product to enter the clinic was TF2, which is in two early Phase I studies in patients with colorectal cancer.

We believe that our portfolio of intellectual property, which includes approximately 179 patents active in the United States and more than 400 other patents issued worldwide, protects our product
candidates and technologies.

Therapeutic Product Candidates

We currently have antibody product candidates in clinical development targeting B-cell NHL, other B-cell mediated diseases, and various
solid tumors. All of our therapeutic product candidates are humanized antibodies, which means that the portion of the antibody that is derived from mouse (murine) DNA sequences is generally less than 10%.

We believe that each of our antibodies has therapeutic potential either when administered as a naked antibody or when conjugated with
therapeutic radioisotopes (radiolabeled), chemotherapeutics, cytokines or other toxins to create unique and potentially more effective treatment options. The attachment of various compounds to antibodies is intended to allow the delivery of these
therapeutic agents to tumor sites with better specificity than conventional radiation therapy or chemotherapy approaches. This treatment method is designed to reduce the total exposure of the patient to the therapeutic agents, which ideally
minimizes debilitating side effects. We are currently focusing our efforts on unlabeled, or naked antibodies and antibodies conjugated with drugs, cytokines, or toxins, and on the use of radioisotopes, such as Y-90, and Iodine-131,
sometimes referred to as I-131.

We also have a number of other product candidates that target solid tumors and hematologic
malignancies, as well as other diseases, in various stages of pre-clinical development, although it is too early to assess which of these, if any, will merit further evaluation in clinical trials. In an effort to permit an effective use of our
resources, our clinical development focus has been reduced to six different antibodies in a limited number of indications.

CD22 Program: Epratuzumab

Our most advanced therapeutic product candidate, epratuzumab, is a humanized antibody which targets CD22, an antigen found on the surface of B-lymphocytes, a type of white blood cells. In contrast to some
other B-cell antibodies, it appears that epratuzumab does not work by ablating all B cells, but instead by modulating them. Epratuzumab does not evoke substantial anti-epratuzumab antibodies in NHL patients, even after repeated dosing, making it a
potentially good candidate for treating patients with a chronic, autoimmune disease. As noted above, we have licensed epratuzumab to UCB for the treatment of all autoimmune disease indications worldwide. We have retained the rights for oncology
indications for which UCB has been granted a buy-in option.

In December 2010, UCB initiated two Phase III clinical trials in
SLE. This autoimmune disease is chronic and potentially fatal, with a variable and unpredictable course. It can affect any part of the body, but most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys and nervous system, and
is characterized by periods of flares, or exacerbations, interspersed with periods of improvement or remission. Although the exact function of CD22 is not fully understood, it is known to be involved in B-cell development, function and survival. B
cells are known to contribute to SLE symptoms by producing antibodies against the bodys own tissues, causing the bodys immune system to turn on itself, attacking cells and tissue, and resulting in inflammation and tissue damage.

---

The two pivotal trials are multi-center, placebo-controlled, randomized, double-blind
studies designed to confirm the clinical efficacy and safety of epratuzumab in the treatment of patients with moderate to severe general SLE, in addition to continuing standard of care treatments. Each study will last a maximum of 54 weeks after
first dose and will randomize 780 patients in the study, with approximately 130 planned investigational sites per study. Top-line results from these trials are expected in the first half of calendar 2014.

UCB launched these pivotal studies based on encouraging results from the Phase IIb study they completed in fiscal year 2010. A total of
227 lupus patients were randomized into this study, 30% with moderate disease activity and 70% with severe disease activity in multiple organ systems. Patients received 1 of 5 epratuzumab treatments or placebo. The primary endpoint of the Phase IIb
study was to measure efficacy at week 12 post therapy based on a comprehensive composite clinical activity index emphasizing BILAG.

Overall, all epratuzumab treatment groups had higher responder rates than placebo, with the 600 mg weekly group and the 2,400 mg combined group reaching statistical significance. Moreover, difference in
responder rates between the epratuzumab 600 mg weekly and 1,200 mg every other week groups and placebo were observed as early as week 8 after treatment, with further improvement at week 12.

Epratuzumab has received Fast Track Product designation from the U.S. Food and Drug Administration, or FDA, for the treatment of patients
with moderate or severe SLE.

Yttrium-90 Clivatuzumab Tetraxetan Program

Yttrium-90 clivatuzumab tetraxetan, or hPAM4 labeled with Y-90, is our therapeutic product candidate for patients with pancreatic
cancer. It is a humanized monoclonal antibody that recognizes a protein called mucin, which is highly specific for pancreatic cancer. Preclinical studies in mice with transplanted human pancreatic cancer demonstrated that the antibody labeled with
Y-90 has activity by itself, as well as in combination with gemcitabine, a radiosensitizing chemotherapeutic that is commonly used to treat patients with this disease. A Phase I dose-escalation (single dose), multi-center, trial of Y-90-clivatuzumab
tetraxetan given alone in relapsed, advanced pancreatic cancer patients has been published in the June 2011 issue of Clinical Cancer Research.

Our current study is a Phase Ib/II, open-label, dose escalation trial of yttrium-90 clivatuzumab tetraxetan administered as fractionated, multi-doses, in combination with gemcitabine as frontline therapy
for patients with Stage III or Stage IV pancreatic cancer. We have recently amended the protocol to allow greater flexibility for repeated dosing cycles.

Results from the initial cohort of 42 patients treated with low-dose gemcitabine at 200 mg/m2were reported as an oral presentation at the June 2011 Society of Nuclear Medicine (SNM) annual meeting. In previous
clinical studies, gemcitabine at such low doses were tolerated and active when given with external radiation therapy.

Of the
42 patients enrolled into this open-label study, 38 (5 Stage III and 33 Stage IV) received at least one cycle of treatments with clivatuzumab and gemcitabine. Overall, the disease control rate, which includes complete response (CR), partial response
(PR) and stable disease (SD), by CT-based RECIST criteria, was 58%, including 6 patients (16%) with PR and 16 patients (42%) with SD as best response. One patient had SD after first treatment cycle that converted to a PR after receiving a
second treatment cycle; but otherwise, the best responses all occurred following the first treatment cycle. These results indicate that there is evidence of anti-tumor activity with this combination therapy.

In terms of survival benefits, the 38 treated patients have a median overall survival (OS) of 7.7 months with 58%
(22/38) having survived for at least 6 months and 26% (10/38) for 1 year or more. Five patients remain alive 15 to 25 months from their start of treatment. Higher Y-90 doses appear to improve survival, where 22 patients treated at the two
highest dose levels (12.0 to 15.0 mCi/m2x 3) had a median
OS of 8.0 months, with 3 patients still alive at 21 to 25 months.

Assessing the impact of retreatment, the 13 retreated
patients had a median OS of 11.8 months compared to 5.4 months for the 25 patients who did not receive more than one treatment cycle.

Yttrium-90 clivatuzumab tetraxetan has Orphan Drug status in both the U.S. and the European
Union, and fast-track status in the U.S. for the treatment of pancreatic cancer.

CD20 Program: Veltuzumab

Similar to CD22, CD20 is an antigen that is expressed on B-lymphocytes. Constructed using the same donor frameworks as
epratuzumab, veltuzumab is an anti-CD20 monoclonal antibody having 90-95% human antibody sequences. Current biological therapy with monoclonal antibodies for NHL includes rituximab ($6.5 billion world-wide sales in 2010 of which 85% were from
oncology), a chimeric antibody comprised of one-third mouse and two-thirds human protein that binds to the CD20 antigen.

We
have licensed veltuzumab to Nycomed, who is responsible for all costs associated with current and future clinical development, manufacturing and commercialization of veltuzumab, in the subcutaneous formulation, for all non-cancer indications
worldwide. Under the terms of the Nycomed Agreement, we retain the right to develop veltuzumab in the field of oncology and have the right to co-promote veltuzumab for the immune thrombocytopenia purpura, or ITP, indication in the United States. In
July 2011, Nycomed initiated its first study of veltuzumab in patients with rheumatoid arthritis, or RA. In June, 2011, we received a third milestone payment from Nycomed related to the clinical development of veltuzumab in patients with RA.

The RA study is a Phase 2 multi-center, double-blind 4-arm trial aimed at comparing three different dose levels of veltuzumab
to placebo. Three hundred patients with moderate to severe RA will be randomized to receive 4 weekly subcutaneous injections of veltuzumab at 80, 160 or 320 mg or placebo. Primary endpoint is efficacy, safety and tolerability of veltuzumab at week
24, with durability of the clinical response and safety of veltuzumab at week 48 as the secondary endpoint

We have also
completed an open-label, multi-center, Phase I/II trial using the subcutaneous formulation of veltuzumab in NHL and CLL. The results in NHL have been published in the April 2011 issue of Haematologica. We are evaluating plans to initiate a Phase III
registration trial for veltuzumab in NHL. Additional funding will be needed before we can proceed with this plan. However, we are continuing the study in CLL after amending it with a different dosing schedule.

CD74 Program: Milatuzumab

CD74 is a transmembrane protein that is highly expressed in MM and other B-cell lymphomas and leukemias, and in certain solid tumors. It actively directs transport from the cell surface to an endosomal
compartment and, as such, is a unique target for antibody-drug conjugate therapy. Also, recent evidence supports a role for CD74 as a signaling molecule in B-cell lymphoma survival. We have observed high expression of CD74 in human NHL, CLL and MM
clinical specimens and cell lines, and have developed milatuzumab, a naked humanized antibody targeting the CD74 antigen, using the same constant regions of the heavy and light chains as epratuzumab, for the therapy of MM, NHL and CLL.

For CLL, an early phase clinical trial evaluating milatuzumab as a single agent is continuing patient accrual, and in NHL milatuzumab is
being administered in combination with veltuzumab in an investigator-sponsored study.

In MM, we are advancing the doxorubicin
conjugate to take advantage of the rapid internalization property of milatuzumab when bound to CD74. A Phase I clinical trial of this drug conjugate is currently enrolling patients with advanced MM at several study sites. The protocol has been
amended to allow for adjusted doses and multiple treatment cycles after hematologic toxicity was encountered at initial dose levels.

Antibody-targeted selective delivery of anticancer drugs against antigens expressed on cancer cells can potentially improve the therapeutic index of anticancer drugs. This product candidate is the
Companys first antibody-drug conjugate to have been entered into human studies.

Yttrium-90 Epratuzumab Tetraxetan Program

Yttrium-90 epratuzumab tetraxetan is our radiolabeled CD22 antibody product candidate for patients with NHL. Radioimmunotherapy, or RAIT,
combines the targeting power of monoclonal antibodies with the cell-damaging ability of localized radiation. When infused into a patient, these radiation-carrying antibodies circulate in the body until they locate and bind to the surface of specific
cells, and then deliver their cytotoxic radiation more directly to the cells. This therapy mainly selects cancer cells, may have fewer side effects than chemotherapy, and may be administered on an outpatient basis in the U.S.

A multi-center Phase I/II study evaluating fractionated dosing of Y-90 epratuzumab tetraxetan (two or three weekly infusions of Y-90
epratuzumab tetraxetan) in 64 adult patients with relapsed/refractory NHL was published in the August 2010 Journal of Clinical Oncology.

The radiolabeled antibody is currently being investigated in a Phase I/II clinical trial for the therapy of patients with aggressive NHL in combination with veltuzumab. This trial, expected to enroll up
to 70 patients, is supported by the NCI, Small Business Innovation Research, or SBIR, grant program.

Labetuzumab-SN-38
Program

Labetuzumab is our proprietary humanized antibody that targets the antigen known as carcinoembryonic antigen,
or CEA. The CEA antigen is abundant at the site of virtually all cancers of the colon and rectum, and is associated with many other solid tumors, such as breast and lung cancers. We have conjugated the antibody with SN-38, the active metabolite of
irinotecan, a FDA approved drug for metastatic colorectal cancer treatment. Although SN-38 is about 3 orders of magnitude more potent than irinotecan, it cannot be given directly to patients because of its toxicity and poor solubility. By linking
SN-38 to labetuzumab, the potent cancer drug can be delivered selectively to tumors, thereby increasing the amount reaching the tumors and minimizing damage to normal tissues and organs.

A Phase I trial to investigate the safety of labetuzumab-SN-38 in patients with colorectal cancer is anticipated to begin patient accrual
at the Memorial Sloan-Kettering Cancer Center in the first half of fiscal year 2012.

Diagnostic Imaging Products

We have continued to transition our focus away from the development and commercialization of new
diagnostic imaging products in order to accelerate the development of our therapeutic product candidates, although we continue to manufacture and commercialize LeukoScan® in territories where regulatory approvals have previously been granted. LeukoScan is indicated for diagnostic imaging to determine the location and extent of
infection/inflammation in bone in patients with suspected osteomyelitis, including patients with diabetic foot ulcers.

Research and
Development Programs

We have historically invested heavily in our research and development programs, spending
approximately $25.4 million for these programs during fiscal year ended June 30, 2011, $19.9 million for fiscal year ended June 30, 2010 and $21.5 million during fiscal year ended June 30, 2009. The expense increase during the 2011
fiscal year resulted primarily from the decrease of research and development expense reimbursement, higher spending for clinical trials and higher patent-related expenses. The expense reduction during the 2010 fiscal year resulted primarily from the
increased level of expense reimbursement received during the year and lower patent-related expenses, partially offset by increased purchases of materials and supplies, higher spending for clinical trials as well as increased salaries and employee
benefits. The above discussion is a brief summary of our principal research and development programs as of August 15, 2011.

Other Antibody-Directed Therapy Approaches

Our majority-owned subsidiary, IBC Pharmaceuticals, Inc., or IBC, has been working on the development of novel cancer therapeutics,
including radioimmunotherapeutics using patented pretargeting technologies with proprietary, bispecific antibodies. They include tumor-targeting antibodies with multiple binding-arms and new carrier peptides that allow attachment of different kinds
of therapeutic and diagnostic isotopes.

One of the new bispecific antibodies is TF2, an antibody constructed using our
proprietary protein engineering platform technology, called Dock-and-Lock, or DNL. It specifically targets the carcinoembryonic antigen, or CEA (specifically CEACAM5) expressed in many human cancers, including colorectal cancer. Unlike conventional
antibodies which can only attach to the receptor, TF2 has been modified to contain an additional binding site that recognizes a radioisotope-carrying peptide. This allows the separate administration of TF2 before the delivery of radioisotope, a
concept known as pretargeting.

TF2 is currently in two investigator-sponsored studies in the U.S. and Europe for pretargeted
imaging and radioimmunotherapy of colorectal cancer. We plan to initiate our own study of TF2 in patients with metastatic colorectal cancer. Patient enrollment into the Phase I trial is expected to begin in the first half of fiscal year 2012.

Our preclinical experience with TF2 pretargeted radiation therapy was encouraging. In animals bearing
CEA-expressing human colonic tumors, pretargeted therapy with TF2 and a small peptide extended median survival from 13 days in untreated animals to 65 days in one model, representing a 5-fold increase in survival, and from 25 days to 48 days in
another model, an almost 2-fold increase in survival. Bone marrow and kidney toxicities were temporary and mild with body weight remaining greater than 93% of baseline in all animals.

The ultimate goal of IBC is to offer cancer patients a more individualized treatment by combining improved molecular imaging with
targeted therapy. Demonstrated tumors localization in imaging studies may predict a more appropriate group of patients that would respond to the subsequent therapy.

Peptides

Since the pretargeting methods being developed with IBC are
showing very high tumor/normal tissue ratios, we have been working on creating a new class of agents using both traditional gamma-emitting isotopes, such as technetium-99m (Tc-99m), and positron-emitting isotopes, such as fluorine-18 (F-18) and
gallium-68 (Ga-68). In 2008, we developed a facile method for the radiolabeling of peptides with F-18, and published the results in the June 2009 issue of the Journal of Nuclear Medicine.

In the new labeling method F-18 was first allowed to react with aluminum in solution, which occurred instantaneously and in a
quantitative manner to form an aluminum-F-18 complex. The complex was then bound or chelated to a chemical group attached to a peptide. By manipulating the chemical structure of the group that the aluminum-F-18 complex attaches to in the peptide, we
were able to improve the yield of the reaction to 87%. The entire process is rapid, requiring only 5 minutes. This is the first method of binding F-18 to peptides via an aluminum conjugate.

The method has since been successfully applied to a bispecific antibody pretargeting study in animals injected with human colonic cancer.
Moreover, F-18 labeled peptides were shown to be stable enough to produce exceptional PET images of receptor-expressing tumors in animals by labeling of specific peptides binding such receptors. Our goal is to improve the labeling process to the
point where we will be capable of radiolabeling peptides and proteins at clinical-scale using single-vial kits, then license the platform technology to companies on a product-by-product basis.

To that end, we have improved the labeling method such that commercial F-18 in saline solution can be used and the labeling of
temperature-sensitive and insensitive peptides or proteins, including antibodies, were

---

achieved. More importantly, as reported by our scientists at the June 2011 annual meeting of SNM, the entire process, which can be validated with USP F-18 in saline, takes approximately 30
minutes and may be reduced to 20 minutes with automation.

In related work, similar synthetic methods have also been used to
prepare peptides that can be radiolabeled with Tc-99m, Ga-68, Indium-111, Lutetium-177, and Yttrium-90, which are being applied to the bispecific pretargeting technology that is being developed through IBC.

Dock-and-Lock Platform Technology

Together with IBC, we have developed a platform technology, called the Dock-and-Lock technology, or DNL, which has the potential for making a considerable number of bioactive molecules of increasing
complexity. DNL utilizes the natural interaction between two human proteins, cyclic AMP-dependent protein kinase, or PKA, and A-kinase anchoring proteins, or AKAPs. The region that is involved in such interaction for PKA is called the dimerization
and docking domain, or DDD, which always is produced in pairs. Its binding partner in AKAPs is the anchoring domain, or AD. When mixed together, DDD and AD will bind with each other spontaneously to form a binary complex, a process termed docking.
Once docked, certain amino acid residues incorporated into DDD and AD will react with each other to lock them into a stably-tethered structure. The outcome of the DNL method is the exclusive generation of a stable complex, in
a quantitative manner that retains the full biological activities of its individual components. Diverse drugs, chemical polymers, proteins, peptides, and nucleic acids are among suitable components that can be linked to either DDD or AD. Since DDD
always appears in pairs, any component that is linked to DDD will have two copies present in the final products. A description of the DNL platform technology was published in the September 15, 2007, Supplement issue of Clinical Cancer
Research.

The DNL method judiciously combines conjugation chemistry and genetic engineering to enable the creation of
novel human therapeutics, and the potential construction of improved recombinant products over those currently on the market. Novel DNL-derived agents that we have created include PEGylated and antibody-conjugated cytokines, mono- and bispecific
multi-valent antibodies, ribonuclease-based immunotoxins, protein complexes for the delivery of small interfering ribonucleic acids and dendrimer-based nanoparticles that are targetable with antibodies.

As with all candidate therapeutic molecules developed by IBC or Immunomedics, the safety and potential efficacy cannot be predicted until
sufficient trials in humans have been conducted.

Patents and Proprietary Rights

Our Patents

We have accumulated a sizeable portfolio of patents and patent applications in the course of our research, which we believe constitutes a very valuable business asset. The major patents relate primarily

Our Licenses

We have obtained licenses from various parties for rights to use, develop and commercialize proprietary technologies and compounds. Currently, we have the following licenses:



| |  |  | Medical Research Council, or MRCWe entered into a license agreement with MRC in May 1994, whereby we have obtained a license for certain patent
rights with respect to the genetic engineering on monoclonal antibodies. Our agreement does not require any milestone payments, nor have we made any payments to MRC to date. Our agreement with MRC, which expires at the expiration of the last of the
licensed patents in 2020, provides for future royalty payments to be made based on a percentage of product sales.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Center for Molecular Medicine and Immunology, or CMMIWe have entered into a license agreement with CMMI in December 2004, whereby we have
licensed certain rights with respect to patents and patent applications owned by CMMI. Dr. Goldenberg, our Chief Medical Officer, Chief Scientific Officer and Chairman of our Board of Directors, is the founder, President and member of the Board
of Trustees of CMMI. No license or milestone payments are required under this agreement. Under the license agreement, which expires at the expiration of the last of the licensed patents in 2023, CMMI will receive future royalty payments in the low
single digits based on a percentage of sales of products that are derived from the CMMI patents. Under the license agreement we are able to decide which patent related expenses we will support. For the fiscal years ended June 30, 2011, 2010 and
2009, we have made payments for CMMI legal expenses regarding patent-related matters of $61,000, $49,000 and $29,000, respectively; however any inventions made independently of us by CMMI are the property of CMMI.

Our Trademarks

The mark IMMUNOMEDICS is registered in the U.S. and nineteen foreign countries and a European Community Trademark has been granted. Our logo is also registered in the U.S. and in two foreign
countries. The mark IMMUSTRIP is registered in the U.S. and Canada. The mark LEUKOSCAN is registered in the U.S. and nine foreign countries, and a European Community Trademark has been granted. In addition, we have applied
for registration in the U.S. for several other trademarks for use on products now in development or testing, and for corresponding foreign and/or European Community Trademarks for certain of those marks. The marks EPRATUCYN and
VELTUCYN have been allowed in the U.S., and International Trademark Registrations and Canadian applications which claim priority to the respective U.S. applications have been filed for EPRATUCYN and VELTUCYN. The
International Registrations request registration in China, Japan and the European Union. Applications have been filed in the U.S. for CLIVATUCYN and MILATUCYN.

Our Trade Secrets

We also rely upon unpatented trade secrets, and there is no assurance that others will not independently develop substantially equivalent
proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technology, or that such rights can be meaningfully protected. We require our employees, consultants, outside scientific collaborators, sponsored
researchers and other advisers to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. These agreements provide that all confidential information developed or made known to the individual during
the course of the individuals relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of our employees, the agreement provides that all inventions conceived by such
employees shall be our exclusive property. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for our trade secrets in the event of unauthorized use or disclosure of such information.

Third Party Rights

Our success also depends in part on our ability to gain access to third party patent and proprietary rights and to operate our business without infringing on third party patent rights. We may be required
to obtain licenses to patents or other proprietary rights from third parties to develop, manufacture and commercialize our product candidates. Licenses required under third-party patents or proprietary rights may not be available on terms acceptable
to us, if at all. If we do not obtain the required licenses, we could encounter delays in product development while we attempt to redesign products or methods or we could be unable to develop, manufacture or sell products requiring these licenses at
all.

Strategic Partnering and Relationships

Nycomed GmbH

During fiscal year 2011, under the terms of the
Nycomed Agreement, we received a milestone payment of $10.0 million from Nycomed related to the clinical development of veltuzumab in RA. The Nycomed Agreement also provides us with an option to co-promote veltuzumab for the treatment of ITP in the
United States. We received two milestone payments of $5.0 million each during fiscal 2010, related to the clinical development of the ITP and RA indications. An initial cash payment of $40.0 million was received in fiscal 2009 upon the signing of
the agreement.

Nycomed is a privately owned pharmaceutical company which agreed to be acquired by Takeda Pharmaceutical
Company Limited. Nycomed provides medicines for hospitals, specialists and general practitioners, as well as over-the-counter medicines in selected markets. Nycomed stated that, as veltuzumab is the first anti-CD20 with a subcutaneous
administration tested in clinical trials, it has the potential to contribute to an improved safety profile versus the currently intravenously administered anti-CD20s. The subcutaneous formulation of veltuzumab should avoid infusion-related side
effects and increase patient and physician convenience. Nycomed believes that anti-CD20s antibodies are considered to be one of the strongest growing segments within the RA market and offer additional market potential by extending into other
autoimmune and inflammatory diseases.

UCB, S.A.

Under the terms of the UCB Agreement, UCB is solely responsible for the development, manufacturing and commercialization of epratuzumab
for the treatment of all autoimmune indications and for the continuation of ongoing clinical trials in SLE. Initially, Immunomedics was responsible for supplying epratuzumab for the completion of clinical trials relating to SLE, the Sjogrens
Phase II Clinical Trial and the SLE Open Label Study as defined in the UCB Agreement. In August 2009, UCB relieved us of our remaining obligation to supply UCB with any further supplies. Therefore, during fiscal 2010 we recorded as revenue the
remainder of the $31.1 million of deferred revenue from UCB.

Other Collaborations

On July 24, 2009, we entered into a partnership and cross-licensing agreement with Alexis Biotech Ltd., London, England, to jointly develop targeted vaccines against cancers that include melanoma and
chronic lymphocytic leukemia, and infectious diseases, such as AIDS. The development will combine the DNL technology with the proprietary HLA-antibody targeting technology from Alexis Biotech. Under the terms of the agreement, there were no payments
exchanged between parties. Both companies will share in the development costs and we will have first worldwide commercialization rights to products derived from the partnership. There are no near term material cash commitments as a result of this
agreement.

On August 12, 2010, we entered into a license and collaboration agreement with GE Healthcare LTD. The
collaboration agreement is for the evaluation of labeling techniques based on our patented F-18 peptide labeling method and is to determine whether our proprietary labeling technology meets with GE Healthcares application needs. The
collaboration agreement provides for payments to Immunomedics for research services regarding novel diagnostic agents and labeling technologies and expense reimbursement for the project, for which we received $101,000. No additional payments are
expected at present for services to be rendered unless specifically requested. This agreement will remain in force for a period of two years.

We conduct research on a number of our programs in collaboration with CMMI and its clinical unit, the Garden State Cancer Center. CMMI performs contracted pilot and pre-clinical trials in scientific areas
of importance to us and also conducts basic research and pre-clinical evaluations in a number of areas of potential interest to us. Dr. David M. Goldenberg, our Chairman of the Board, Chief Scientific Officer and Chief Medical Officer, is
the President and a Member of the Board of Trustees of CMMI.

The following table indicates the new research grant awards we
received from the National Institute of Health (NIH) during the 2011 fiscal year.

We also collaborate with numerous other academic and research centers. Our academic collaborators have
included such institutions as the Erasme University Hospital, Brussels, Belgium; University of Nijmegen, The Netherlands; Institut national de la sante et de la recherche medicale, or INSERM, Nantes, France; University Medical Center Göttingen,
Germany; St. Bartholomews Hospital, London, England; New York Presbyterian Hospital  Weill Cornell Medical College; University of Ohio Cancer Center; M.D. Anderson Cancer Center; and Roswell Park Cancer Institute. We believe such
academic research collaboration may identify new and improved products and techniques for diagnosing and treating various cancers and infectious diseases.

Government Regulation

Regulatory Compliance

Our research and development activities, including testing in laboratory animals and in humans, our manufacture of antibodies, as well as
the handling, labeling and storage of the product candidates that we are developing, are all subject to stringent regulation, primarily by the FDA in the U.S. and by comparable authorities in other countries. If for any reason we are unable to
comply with applicable requirements there will likely occur various adverse consequences, including one or more delays in approval, or even the refusal to approve, product licenses or other applications, the suspension or termination of clinical
investigations, the



10



---

revocation of approvals previously granted, as well as fines, criminal prosecution, recall or seizure of products, injunctions against shipping products and total or partial suspension of
production and/or refusal to allow us to enter into governmental supply contracts.

The process of obtaining requisite FDA
approval is costly and time consuming even in the best of circumstances. For a new human drug or biological product to be marketed in the United States, current FDA requirements include: (i) the successful conclusion of pre-clinical tests to
gain preliminary information on the products safety; (ii) the filing with the FDA of an IND to conduct human clinical trials for drugs or biologics; (iii) the successful completion of human clinical investigations to establish the
safety and efficacy of the product candidate for its intended indication; and (iv) the filing and then acceptance and approval by the FDA of a New Drug Application, or NDA, for a drug product, or a Biological License Application, or BLA, for a
biological product, in either case to allow commercial distribution of the drug or biologic.

Orphan Drug Act

To date, we have successfully obtained Orphan Drug designation by the FDA under the Orphan Drug Act of 1983 for
epratuzumab for non-Hodgkins lymphoma, yttrium-90 labeled PAM4 for pancreatic cancer, labetuzumab for ovarian, pancreatic and small cell lung cancers, and milatuzumab for multiple myeloma and chronic lymphocytic leukemia. There can be no
assurance, however, that our competitors will not receive approval of other different drugs or biologics for treatment of the diseases for which our products and product candidates are targeted.

Other Regulatory Considerations

We are also subject to regulation under the Occupational Safety and Health Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act, The Clean Air Act, and other current and
potential future federal, state, or local regulations. Our research and development activities involve the controlled use of hazardous materials, chemicals, biological materials and various radioactive compounds. We believe that our procedures
comply with the standards prescribed by state and federal regulations; however, the risk of injury or accidental contamination cannot be completely eliminated.

We are subject to the U.S. Foreign Corrupt Practices Act, which prohibits corporations and individuals from engaging in certain activities to obtain or retain business or to influence a person working in
an official capacity. Under this act, it is illegal to pay, offer to pay, or authorize the payment of anything of value to any foreign government official, government staff member, political party or political candidate in an attempt to obtain or
retain business or to otherwise influence a person working in an official capacity. Our present and future business has been and will continue to be subject to various other laws and regulations.

Pricing Controls

The levels of revenues and profitability of biopharmaceutical companies may be affected by the continuing efforts of government and third party payers to contain or reduce the costs of health care through
various means. For example, in certain foreign markets, pricing reimbursement or profitability of therapeutic and other pharmaceutical products is subject to governmental control. In the U. S., there have been, and we expect that there will continue
to be, a number of federal and state proposals to implement similar governmental pricing control. While we cannot predict whether any such legislative or regulatory proposals will be adopted, the adoption of such proposals could have a material
adverse effect on our business, financial condition and profitability.

Third Party Reimbursement

In addition, in the U. S. and elsewhere, sales of therapeutic and other pharmaceutical products are dependent in part on the availability
of reimbursement to the consumer from third party payers such as government and private insurance plans. Third party payers are increasingly challenging the prices charged for medical products



11



---

and services. We cannot assure you that any of our products will be considered cost effective and that reimbursement to the consumer will be available or will be sufficient to allow us to sell
our products on a competitive and profitable basis.

Competition

Competition in the biopharmaceutical industry is intense and based significantly on scientific and technological factors such as the
availability of patent and other protection for technology and products, the ability to commercialize technological developments and the ability to obtain governmental approval for testing, manufacturing and marketing. We compete with specialized
biopharmaceutical firms in the United States, Europe and elsewhere, as well as a growing number of large pharmaceutical companies. A number of companies, including Biogen Idec, Roche, GlaxoSmithKline, Human Genome Sciences, Seattle Genetics, Merck
Serono, Genmab, Amgen Inc., Bristol-Myers Squibb, Bayer Healthcare Pharmaceuticals, Pfizer, AstraZeneca and Eli Lilly are engaged in the development of therapeutic autoimmune and oncology products. For example, Human Genome Sciences and their
corporate partner, GlaxoSmithKline recently received approval from the FDA for their human monoclonal antibody against B-lymphocyte stimulator or BlyS, for the therapy of patients with SLE. Many of these companies have significantly greater
financial, technical and marketing resources than we do. Many major pharmaceutical companies have developed or acquired internal biotechnology capabilities or made commercial arrangements with other biopharmaceutical companies. These companies, as
well as academic institutions, governmental agencies and private research organizations, also compete with us in recruiting and retaining highly qualified scientific, technical and professional personnel and consultants. Our ability to compete
successfully with other companies in the biopharmaceutical field will also depend to a considerable degree on the continuing availability of capital to us.

Marketing, Sales and Distribution

At present we have
only limited marketing and sale capabilities as we focus our efforts on developing our therapeutic product candidates. We will continue to manufacture and market LeukoScan® with our sales force and provide technical support directly to customers. We also have agreements with third parties to market LeukoScan® that provide customer support and distribution of the products.

Our European operations are headquartered in Darmstadt, Germany. We have also established sales representation in
most major European markets. We service other markets through the appointment of local organizations that provide sales and marketing support as well as local product redistribution. We have a distribution agreement with Logosys Logistik GmbH,
whereby Logosys packages and distributes LeukoScan® in the European Union.

Manufacturing

We
operate a bioreactor facility at our Morris Plains, New Jersey location. This facility is used for the production of all of our therapeutic product candidates for clinical trials, and potentially for commercial quantities as well.

We manufacture LeukoScan® for commercial sale at our facility in Morris Plains, New Jersey. The Committee on Proprietary Medicinal Products of the European Commission approved the
manufacturing facility and product manufacturing processes for LeukoScan in May 1998. We also perform antibody processing and purification of all our therapeutic product candidates at this facility. We have scaled-up our antibody purification and
fragmentation manufacturing processes for our diagnostic imaging agents to permit us to produce commercial levels of product. In April 2005, we entered into an agreement with BAG GmbH, Lich, Germany for the final formulation, fill and lyophilization
of Leukoscan®.

As part of the Nycomed Agreement we were obligated for the manufacture and sale to Nycomed of veltuzumab for a supply level indicated in the Nycomed Agreement at a price as defined in the Nycomed
Agreement. In December 2009, we completed our obligations to supply Nycomed with veltuzumab. As part of



12



---

the UCB Agreement we were responsible for the manufacture of epratuzumab for the completion of the ongoing clinical trials relating to SLE, and if requested by UCB (and within our production
capacity), to manufacture and supply the initial commercial launch of epratuzumab for the treatment of SLE and for certain future clinical trials for another autoimmune disease indication, if necessary. In August 2009, UCB relieved us of our
obligations to supply UCB with epratuzumab.

Manufacturing Regulatory Considerations

In addition to regulating and auditing human clinical trials, the FDA regulates and inspects equipment, facilities and processes used in
the manufacturing of such products prior to providing approval to market a product. If after receiving clearance from the FDA, a material change is made in manufacturing equipment, location, or process, additional regulatory review may be required.
We must also adhere to current Good Manufacturing Practice and product-specific regulations enforced by the FDA through its facilities inspection program. The FDA also conducts regular, periodic visits to re-inspect equipment, facilities, and
processes following the initial approval. If, as a result of these inspections, the FDA determines that our equipment, facilities or processes do not comply with applicable FDA regulations and conditions of product approval, the FDA may seek civil,
criminal or administrative sanctions and/or remedies against us, including the suspension of our manufacturing operations.

LeukoScan® and certain of our other imaging agents are derived from
the fluids produced in mice. Regulatory authorities, particularly in Europe, have expressed concerns about the use of these fluids for the production of monoclonal antibodies. These regulatory authorities may determine that our quality control
procedures for these products are inadequate. In the event we have to discontinue the use of mouse fluids, we may not have the resources at the time to acquire the necessary manufacturing equipment and expertise that we will need to make the changes
in our development programs.

Employees

As of August 15, 2011, we employed 121 persons on a full-time basis, of whom 23 were in research and development departments, 17 of whom were engaged in clinical research and regulatory affairs, 56
of whom were engaged in operations and manufacturing and quality control, and 25 of whom were engaged in finance, administration, sales and marketing. Of these employees, 59 hold M.D., Ph.D. or other advanced degrees. We believe that while we have
been successful to date in attracting skilled and experienced scientific personnel, competition for such personnel continues to be intense and there can be no assurance that we will continue to be able to attract and retain the professionals we will
need to grow our business. Our employees are not covered by a collective bargaining agreement and we believe that our relationship with our employees is excellent.

|Item 1A. | Risk Factors
|-------- | ------------

Factors That May Affect Our Business and Results of Operations

Our
business is subject to certain risks and uncertainties, each of which could materially adversely affect our business, financial condition, cash flows and results of operations.

Risks Relating to Our Business, Operations and Product Development

We have a long history of operating losses and it is likely that our operating expenses will continue to exceed our revenues for the
foreseeable future.

We have incurred significant operating losses since our formation in 1982. As of June 30,
2011, we had an accumulated deficit of approximately $217.9 million. We continue to spend our cash resources to fund our research and development programs and, subject to adequate funding, we expect these expenses to increase for the foreseeable
future. Our only significant sources of revenue in recent years have been derived from our existing licensing agreements with UCB and Nycomed. The timing of when we are able to record licensing fee revenue from such agreements has varied
historically and may result in quarterly or annual profits or losses that are not necessarily reflective of our business operations or related cash flows. For example, for the year ended June 30, 2010, we were profitable primarily because of
the recognition during the period of all remaining $31.1 million of deferred revenue resulting from our 2006 agreement with UCB. Whereas, during the 2010 fiscal year, we used $7.1 million in cash to fund operations. There can be no assurance that we
will be profitable in future quarters or other periods. Additionally, the only product sales we have earned to date have come from the limited sales of our diagnostic imaging products. In addition, we have made the strategic decision to de-emphasize
sales of our diagnostic products and focus on our therapeutic pipeline. We have never had product sales of any therapeutic product. We expect to experience significant operating losses as we invest further in our research and development activities
while simultaneously attempting to develop and commercialize our other therapeutic product candidates. If we are unable to develop commercially viable therapeutic products or to license them to third parties, it is likely that we will never achieve
significant revenues or become profitable, either of which would jeopardize our ability to continue as a going concern.

Our most advanced therapeutic product candidates are still only in the clinical development stage, and will require us to raise
capital in the future in order to fund further expensive and time-consuming studies before they can even be submitted for final regulatory approval.

Our most advanced therapeutic product candidates are still in the clinical development stage and will not be available for commercial sale any time soon, if ever. In order to complete the clinical
development process for each of our product candidates, it will be necessary to invest significant financial resources, and devote a great deal of time and effort, just to reach the point where an application for final FDA or foreign regulatory
approval can be submitted. In addition, we will need to raise additional capital to finance the costly process of obtaining approval for any of our current products should we get to that stage of product development. Given the current downturn in
the economy, however, financing may not be available to us when we need it or on terms acceptable to us.

Clinical trials
involve the administration of a product candidate to patients who are already extremely ill, making patient enrollment often difficult and expensive. Moreover, even in ideal circumstances where the patients can be enrolled and then followed for the
several months or more required to complete the study, the trials can be suspended, terminated or otherwise fail for any number of reasons, including:



| |  |  | later-stage clinical trials may raise safety or efficacy concerns not readily apparent in earlier trials;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | unforeseen difficulties in manufacturing the product candidate in compliance with all regulatory requirements and in the quantities needed to complete
the trial may be cost-prohibitive;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



15

| |  |  | while underway, the continuation of clinical trials may be delayed, suspended or terminated due to modifications to the clinical trials protocols
based on interim results obtained;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our collaboration partner may suspend or cease trials in their sole discretion;
| | - |  | -------------------------------------------------------------------------------



| |  |  | during the long trial process alternative therapies may become available which make further development of the product candidate impracticable; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if we are unable to obtain the additional capital we need to fund all of the clinical trials we foresee, we may be forced to cancel or otherwise
curtail some important trials.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any failure or substantial delay in successfully completing clinical trials
for our product candidates, particularly the ongoing trials for our most advanced product candidates, epratuzumab and veltuzumab, could severely harm our business and results of operation.

Should the clinical development process be successfully completed, our ability to derive revenues from the sale of therapeutics
will depend upon our first obtaining FDA as well as foreign regulatory approvals, all of which are subject to a number of unique risks and uncertainties.

Even if we are able to demonstrate the safety and efficacy of our product candidates in clinical trials, if we fail to gain timely approval to commercialize our product candidates from the FDA and other
foreign regulatory authorities, we will be unable to generate the revenues we will need to build our business. These approvals may not be granted on a timely basis, if at all, and even if and when they are granted they may not cover all the
indications for which we seek approval. For example, while we may develop a product candidate with the intention of addressing a large, unmet medical need, the FDA may only approve the use of the drug for indications affecting a relatively small
number of patients, thus greatly reducing the market size and our potential revenues. The approvals may also contain significant limitations in the form of warnings, precautions or contraindications with respect to conditions of use, which could
further narrow the size of the market. In certain countries, even if the health regulatory authorities approve a drug, it cannot be marketed until pricing for the drug is also approved. Finally, even after approval can be obtained, we may be
required to recall or withdraw a product as a result of newly discovered safety or efficacy concerns, either of which would have a materially adverse effect on our business and results of operations.

In order to fund future operations, we will need to raise significant amounts of additional capital. Because it can be difficult
for a small-cap company like ours to raise equity capital on acceptable terms and given the continued downturn in the economy, we cannot assure you that we will be able to obtain the necessary capital when we need it, or on acceptable terms, if at
all.

Even if our technologies and product candidates are superior, if we lack the capital needed to bring our future
products to market, we will never be successful. We have obtained the capital necessary to fund our research and development programs to date primarily from the following sources:



| |  |  | $40.0 million from Nycomed in fiscal 2009 to license the rights to develop, manufacture and commercialize veltuzumab for the treatment of all
non-cancer indications, and $10.0 million in milestone payments in both fiscal years 2011 and 2010 under the terms of this agreement with Nycomed;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | $38.0 million from UCB in fiscal 2006 to license the rights to develop, manufacture and commercialize epratuzumab for the treatment of all autoimmune
disease indications;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | approximately $259.0 million from the public and private sale of our debt and equity securities through June 30, 2011; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | limited product sales of
CEA-Scan® and LeukoScan®, licenses, grants and interest income from our investments.
| | - |  | -------------------------------------------------------------------------------------------------------------

---

Based on our expected cash utilization rate, we believe we have adequate cash to fund our
operations and research and development programs through the next twelve months. We are also evaluating plans to initiate a Phase III registration trial of veltuzumab in non-Hodgkins lymphoma and a Phase III registration trial for clivatuzumab
in pancreatic cancer. We will need to obtain additional funding in the event we decide to begin these trials.

We will need to
raise additional capital in order to obtain the necessary regulatory approvals and then commercialize our therapeutic product candidates. Our capital requirements are dependent on numerous factors, including:



| |  |  | the rate at which we progress our research programs and the number of product candidates we have in pre-clinical and clinical development at any one
time;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cost of conducting clinical trials involving patients in the United States, Europe and possibly, elsewhere;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | our need to establish the manufacturing capabilities necessary to produce the quantities of our product candidates we project we will need;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the time and costs involved in obtaining FDA and foreign regulatory approvals;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the cost of first obtaining, and then defending, our patent claims and other intellectual property rights;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the success of Nycomed and UCB in meeting the clinical development and commercial milestones for veltuzumab and epratuzumab, respectively; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to enter into licensing and other collaborative agreements to help off-set some of these costs.
| | - |  | -----------------------------------------------------------------------------------------------------------

There may be additional cash requirements for many reasons, including, but not limited to, changes in our research and development plans,
the need for unexpected capital expenditures or costs associated with any acquisitions of other businesses and assets or technologies that we may choose to undertake. If we deplete our existing capital resources, we will be required to either obtain
additional capital quickly, or else significantly reduce our operating expenses and capital expenditures, either of which could have a material adverse effect on us.

Our ability to raise future capital on acceptable terms will depend not only upon our operating performance, but also on conditions in the public and private debt and equity markets, as well as the
overall performance of other companies in the biopharmaceutical and biotechnology sectors. Because of the current downturn in the economy and adverse conditions in the public and private debt and equity markets, financing may not be available to us
when we need it on terms we find acceptable, if at all. Furthermore, the terms of any such debt or equity financing may include covenants which limit our future ability to manage the business, contain preferences, privileges and rights superior to
those enjoyed by holders of our common stock or cause substantial dilution to our existing stockholders.

If we, or our
collaboration partners, cannot successfully and efficiently manufacture the compounds that make up our products and product candidates, our ability, and the ability of our collaboration partners, to sell products and conduct clinical trials will be
impaired.

Our ability to conduct our pre-clinical and clinical research and development programs depends, in large
part, upon our ability to manufacture our proprietary compounds in accordance with FDA and other regulatory requirements. While we have completed construction on the major expansion of our manufacturing facilities in New Jersey in anticipation of
our current and future needs, we have limited historical experience in manufacturing these compounds in significant quantities, and we may not be able to do so in the quantities required to commercialize these products. Any interruption in
manufacturing at this site, whether by natural acts or otherwise, could significantly and adversely affect our operations, and delay our research and development programs.



17



---

We and our collaboration partners also depend on third parties to provide certain raw
materials, manufacturing and processing services. All manufacturers of pharmaceutical products must comply with current Good Manufacturing Practice regulations, or cGMPs, required by the FDA and other regulatory agencies. Such regulations address,
among other matters, controls in manufacturing processes, quality control and quality assurance requirements and the maintenance of proper records and documentation. The FDA and other regulatory agencies routinely inspect manufacturing facilities.
The FDA generally will issue a notice on Form 483 if it finds issues with respect to its inspections. Certain of our contract manufacturers have received Form 483 notices. If our manufacturing facility or those facilities of our partners and our
respective contract manufacturers or processors do not comply with applicable cGMPs and other regulatory requirements, we may be subject to product liability claims, we may be unable to meet clinical demand for our products, and we could suffer
delays in the progress of clinical trials for products under development.

We are dependent upon Nycomed for the final
development and commercialization of veltuzumab for the treatment of all non- cancer indications worldwide and upon UCB for the final development and commercialization of epratuzumab for the treatment of autoimmune disease indications worldwide and
they may not be successful.

We have licensed the exclusive worldwide rights of two of our most advanced therapeutic
compounds,veltuzumab (to Nycomed) andepratuzumab (to UCB). As a result, Nycomed and UCB are solely responsible, and we are depending upon them, for completing the clinical development of these compounds,obtaining all
necessary regulatory approvals, and then commercializing and manufacturing the compounds for sale. If they do not fully perform their responsibilities under our agreements, or if the clinical trials to be conducted are not initiated, successful or
are terminated by them for any other reason, our ability to commercialize these product candidates in the future, as well as other product candidates we have in development which are closely related to them,would be severely jeopardized. In
such event, it is likely we would never receive any additional milestone payments or royalties that we are eligible to receive under our agreements with Nycomed and UCB, and our ability to fund the development and testing of our other product
candidates would be adversely affected.

We may not successfully establish and maintain collaborative and licensing
arrangements, which could adversely affect our ability to develop and commercialize our product candidates. Our future collaboration partners may not adequately perform their responsibilities under our agreement, which could adversely affect our
development and commercialization program.

A key element of our business strategy is to develop, market and
commercialize our product candidates through collaborations with more established pharmaceutical companies. We may not be able to maintain or expand these licenses and collaborations or establish additional licensing and collaboration
arrangements necessary to develop and commercialize our product candidates. Even if we are able to maintain or establish licensing or collaboration arrangements, these arrangements may not be on favorable terms and may contain provisions that
will restrict our ability to develop, test and market our product candidates. Any failure to maintain or establish licensing or collaboration arrangements on favorable terms could adversely affect our business prospects, financial condition or
ability to develop and commercialize our product candidates.

We expect to rely at least in part on third party collaborators
to perform a number of activities relating to the development and commercialization of our product candidates, including the manufacturing of product materials, the design and conduct of clinical trials for our product candidates, and potentially
the obtaining of regulatory approvals and marketing and distribution of any successfully developed products. Our collaborative partners may also have or acquire rights to control aspects of our product development and clinical programs. As
a result, we may not be able to conduct these programs in the manner or on the time schedule we currently contemplate. In addition, if any of these collaborative partners withdraw support for our programs or product candidates or otherwise impair
their development our business could be negatively affected. To the extent we undertake any of these activities internally, our expenses may increase.

In addition, our success depends on the performance of our collaborators of their responsibilities under these arrangements. Some potential collaborators may not perform their obligations in a timely
fashion or in a manner



18



---

satisfactory to us. Because such agreements may be exclusive, we may not be able to enter into a collaboration agreement with any other company covering the same product field during the
applicable collaborative period. In addition, our collaborators competitors may not wish to do business with us at all due to our relationship with our collaborators. If we are unable to enter into additional product discovery and
development collaborations, our ability to sustain or expand our business will be significantly diminished.

Our future
success will depend upon our ability to first obtain and then adequately protect our patent and other intellectual property rights, as well as avoiding the infringement of the rights of others.

Our future success will be highly dependent upon our ability to first obtain and then defend the patent and other intellectual property
rights necessary for the commercialization of our product candidates. We have filed numerous patent applications on the technologies and processes that we use in the U.S. and certain foreign countries. Although we have obtained a number of issued
U.S. patents to date, the patent applications owned or licensed by us may not result in additional patents being issued. Moreover, these patents may not afford us the protection we need against competitors with similar technologies or products.

The successful development of therapeutic products frequently requires the application of multiple technologies that may be
subject to the patent or other intellectual property rights of third parties. Although we believe it is likely we will need to license technologies and processes from third parties in the ordinary course of our business, we are not currently aware
of any material conflict involving our technologies and processes with any valid patents or other intellectual property rights owned or licensed by others. In the event that a third party was to claim such a conflict existed, they could sue us for
damages as well as seek to prevent us from commercializing our product candidates. It is possible that a third party could successfully claim that our products infringe on their intellectual property rights. Uncertainties resulting from the
litigation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Any patent litigation or other proceeding, even if resolved in our favor, would require
significant financial resources and management time.

Some of our competitors may be able to sustain these costs more
effectively than we can because of their substantially greater financial and managerial resources. If a patent litigation or other proceeding is resolved unfavorably to us, we may be enjoined from manufacturing or selling our products without a
license from the other party, in addition to being held liable for significant damages. We may not be able to obtain any such license on commercially acceptable terms, if at all.

In addition to our reliance on patents, we attempt to protect our proprietary technologies and processes by relying on trade secret laws,
nondisclosure and confidentiality agreements and licensing arrangements with our employees and other persons who have access to our proprietary information. These agreements and arrangements may not provide meaningful protection for our proprietary
technologies and processes in the event of unauthorized use or disclosure of such information. In addition, our competitors may independently develop substantially equivalent technologies and processes or otherwise gain access to our trade secrets
or technology, either of which could materially and adversely affect our competitive position.

We face substantial
competition in the biotechnology industry and may not be able to compete successfully against one or more of our competitors.

The biotechnology industry is highly competitive, particularly in the area of diagnostic and therapeutic oncology and autoimmune disease products. In recent years, there have been extensive technological
innovations achieved in short periods of time, and it is possible that future technological changes and discoveries by others could result in our products and product candidates quickly becoming uncompetitive or obsolete. A number of companies,
including Biogen Idec, Roche, GlaxoSmithKline, Human Genome Sciences, Seattle Genetics, Trubion Pharmaceuticals, Zymogenetics, Merck Serono, Genmab, Amgen Inc., Bristol-Myers Squibb, Bayer Healthcare Pharmaceuticals, Pfizer, AstraZeneca and Eli
Lilly, are engaged in the development of therapeutic



19



---

autoimmune and oncology products. For example, Human Genome Sciences and their corporate partner, GlaxoSmithKline recently received approval from the FDA for their human monoclonal antibody
against B-lymphocyte stimulator or BlyS, for the therapy of patients with SLE. Many of these companies have significantly greater financial, technical and marketing resources than we do. In addition, many of these companies have more established
positions in the pharmaceutical industry and are therefore better equipped to develop, commercialize and market oncology and autoimmune disease products. Even some smaller competitors may obtain a significant competitive advantage over us if they
are able to discover or otherwise acquire patentable inventions, form collaborative arrangements or merge with larger pharmaceutical companies.

We expect to face increasing competition from universities and other non-profit research organizations. These institutions carry out a significant amount of research and development in the field of
antibody-based technologies and they are increasingly aware of the commercial value of their findings. As a result, they are demanding greater patent and other proprietary rights, as well as licensing and future royalty revenues.

We may be liable for contamination or other harm caused by hazardous materials that we use in the operations of our business.

In addition to laws and regulations enforced by the FDA, we are also subject to regulation under various other
foreign, federal, state and local laws and regulations. Our manufacturing and research and development programs involve the controlled use of viruses, hazardous materials, chemicals and various radioactive compounds. The risk of accidental
contamination or injury from these materials can never be completely eliminated, and if an accident occurs we could be held liable for any damages that result, which could exceed our available resources.

The nature of our business exposes us to significant liability claims, and our insurance coverage may not be adequate to cover any
future claims.

The use of our compounds in clinical trials and any future sale exposes us to liability claims that
could be substantial. These claims might be made directly by healthcare providers, medical personnel, patients, consumers, pharmaceutical companies and others selling or distributing our compounds. While we currently have product liability insurance
that we consider adequate for our current needs, we may not be able to continue to obtain comparable insurance in the future at an acceptable cost, if at all. If for any reason we cannot maintain our existing or comparable liability insurance, our
ability to clinically test and market products could be significantly impaired. Moreover, the amount and scope of our insurance coverage, as well as the indemnification arrangements with third parties upon which we rely, may be inadequate to protect
us in the event of a successful product liability claim. Any successful claim in excess of our insurance coverage could materially and adversely affect our financial condition and operating results.

The loss of any of our key employees could adversely affect our operations.

We are heavily dependent upon the talents of Dr. Goldenberg, our Chairman of the Board, Chief Scientific Officer and Chief Medical
Officer, and Ms. Sullivan, our President and Chief Executive Officer, as well as certain other key personnel. If Dr. Goldenberg, Ms. Sullivan or any of our other key personnel were to unexpectedly leave our Company, our business and
results of operations could be materially and adversely affected. In addition, as our business grows we will need to continue to attract additional management and scientific personnel. Competition for qualified personnel in the biotechnology and
pharmaceutical industries is intense and we may not be successful in our recruitment efforts. If we are unable to attract, motivate and retain qualified professionals, our operations could be materially and adversely affected.

Certain potential for conflicts of interest, both real and perceived, exist which
could result in expensive and time-consuming litigation.

Certain members of our senior management and Board of
Directors have relationships and agreements, both with us as well as among themselves and their respective affiliates, which create the potential for both real, as well as perceived, conflicts of interest. These include Dr. David M.
Goldenberg, our Chairman, Chief Scientific Officer and Chief Medical Officer, Ms. Cynthia L. Sullivan, our President and Chief Executive Officer (who is also the wife of Dr. Goldenberg), and certain companies with which we do
business, including the Center for Molecular Medicine and Immunology and the Garden State Cancer Center (which operates as the clinical arm of CMMI to facilitate the translation of CMMIs research efforts in the treatment of patients),
collectively defined as CMMI. For example, Dr. Goldenberg is the President and a Trustee of CMMI, a not-for-profit cancer research center that we use to conduct certain research activities. For the fiscal year ended June 30, 2011, we have
incurred $0.3 million of research expenses for activities conducted by CMMI on our behalf. Further, Dr. Goldenbergs employment agreement with us permits him to devote more of his time working for CMMI than for us, and other key personnel
of our company also have research collaborations with CMMI. Dr. Goldenberg is also a minority stockholder, director and officer of our majority-owned subsidiary, IBC. Dr, Goldenberg is the primary inventor of new intellectual property for
Immunomedics and IBC and is largely responsible for allocating ownership between the two companies.

As a result of these and
other relationships, the potential for both real and perceived conflicts of interest exists and disputes could arise over the allocation of funds, research projects and ownership of intellectual property rights. In addition, in the event that we
become involved in stockholder litigation regarding these potential conflicts, we might be required to devote significant resources and management time defending the company from these claims, which could adversely affect our results of operations.

Given that autoimmune and cancer therapeutics such as the ones we are developing can cost upwards of $20,000 per
treatment, even if our product candidates become available for sale it is likely that federal and state governments, insurance companies and other payers of health care costs will try to first limit the use of these drugs to certain patients, and
may be reluctant to provide a level of reimbursement that permits us to earn a significant profit on our investment, if any.

Our ability to successfully commercialize therapeutic products will depend, in significant part, on the extent to which hospitals and physicians can obtain appropriate reimbursement levels for the cost of
our products and related treatment. Third-party payers are increasingly challenging the prices charged for diagnostic and therapeutic products and related services. In addition, legislative proposals to reform health care or reduce government
insurance programs may result in lower prices or the actual inability of prospective customers to purchase our products. Furthermore, even if reimbursement is available, it may not be available at price levels sufficient for us to realize a positive
return on our investment.

A portion of our funding has come from federal government grants and research contracts. Due
to reductions in funding, we may not be able to rely on these grants or contracts as a continuing source of funds.

During the last few years, we have generated revenues from awards made to us by the NIH to partially fund some of our programs. We cannot
rely on grants or additional contracts as a continuing source of funds. Funds available under these grants and contracts must be applied by us toward the research and development programs specified by the government rather than for all our programs
generally. The governments obligation to make payments under these grants and contracts is subject to appropriation by the U.S. Congress for funding in each year. It is possible that Congress or the government agencies that administer these
government research programs will continue to decide to scale back these programs or terminate them due to their own budgetary constraints, as they have recently been doing. Additionally, these grants and research contracts are subject to adjustment
based upon the results of periodic audits performed on behalf of the granting authority. Consequently, the government may not award grants or research contracts to us in the future, and any amounts that we derive from existing



21



---

awards may be less than those received to date. In those circumstances, we would need to provide funding on our own, obtain other funding, or scale back or terminate the affected program. In
particular, we cannot assure you that any currently-contemplated or future efforts to obtain funding for our product candidate programs through government grants or contracts will be successful, or that any such arrangements which we do conclude
will supply us with sufficient funds to complete our development programs without providing additional funding on our own or obtaining other funding.

Risks Related to Government Regulation of our Industry

Legislative
or regulatory reform of the healthcare system may affect our ability to sell our products profitably.

In both the
United States and certain foreign jurisdictions, there have been a number of legislative and regulatory proposals to change the healthcare system in ways that could impact our ability to sell our future products and profitability. On March 23,
2010, President Obama signed into law the Patient Protection and Affordable Care Act (PPACA), which includes a number of health care reform provisions and requires most U.S. citizens to have health insurance. Effective January 1, 2010, the new
law increases the minimum Medicaid drug rebates for pharmaceutical companies, expands the 340B drug discount program, and makes changes to affect the Medicare Part D coverage gap, or donut hole. The law also revises the definition of
average manufacturer price for reporting purposes (effective October 1, 2011), which could increase the amount of the Companys Medicaid drug rebates to states, once the provision is effective. The new law also imposes a
significant annual fee on companies that manufacture or import branded prescription drug products (beginning in 2010). Substantial new provisions affecting compliance also have been added, which may require modification of business practices with
health care practitioners.

The reforms imposed by the new law will significantly impact the pharmaceutical industry; however,
the full effects of PPACA cannot be known until these provisions are implemented and the Centers for Medicare & Medicaid Services and other federal and state agencies issue applicable regulations or guidance. Moreover, in the coming years,
additional change could be made to governmental healthcare programs that could significantly impact the success of our future products, and we could be adversely affected by current and future health care reforms.

Our industry and we are subject to intense regulation from the U.S. Government and such other governments and quasi-official
regulatory bodies where our products are and product candidates may be sold.

These governmental and other regulatory
risks include:



| |  |  | Clinical development is a long, expensive and uncertain process, delay and failure can occur at any stage of our clinical trials;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our clinical trials are dependent on patient enrollment and regulatory approvals, we do not know whether our planned trials will begin on time, or at
all, or will be completed on schedule or at all;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The FDA or other regulatory authorities do not approve a clinical trial protocol or place a clinical trial on hold;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | If the clinical development process is completed successfully, our ability to derive revenues from the sale of therapeutics will depend on our first
obtaining FDA or other comparable foreign regulatory approvals, each of which are subject to unique risks and uncertainties;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | There is no assurance that we will receive FDA or corollary foreign approval for any of our product candidates for any indication; we are subject to
government regulation for the commercialization of our product candidates;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have not received regulatory approval in the United States or any foreign jurisdiction for the commercial sale of any of our product candidates; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



22

| |  |  | We may be liable for contamination or other harm caused by hazardous materials used in the operations of our business.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

Risks Related to Our Securities

Our common stock may be delisted from the NASDAQ Global Market, or NASDAQ.

If the bid price of our common stock falls below $1.00 for an extended period, or we are unable to continue to meet NASDAQs listing maintenance standards for any other reason, our common stock could
be delisted from the NASDAQ.

If our stock is not accepted for listing on the NASDAQ, we will make every possible effort to
have it listed on the Over the Counter Bulletin Board, or the OTC Bulletin Board. If our common stock were to be traded on the OTC Bulletin Board, the Securities Exchange Act of 1934, as amended, and related Securities and Exchange Commission, or
SEC, rules would impose additional sales practice requirements on broker-dealers that sell our securities. These rules may adversely affect the ability of stockholders to sell our common stock and otherwise negatively affect the liquidity, trading
market and price of our common stock.

If our common stock would not be able to be traded on the OTC Bulletin Board, we would
make every effort to have it available for trading on the National Quotation Bureaus Pink Sheets, or the Pink Sheets. The Pink Sheets market consists of security firms who act as market makers in the stocks, usually, of very small companies.
The bid and asked prices are not quoted electronically, but are quoted daily in hard copy which is delivered to firms that subscribe. Stocks that trade in the Pink Sheets are usually not as liquid as those that trade in electronic
markets and, often time, the difference between the bid and the asked prices are substantial. As a result, if our common stock were traded on the Pink Sheets, there would likely be a further negative affect on the liquidity, trading market and price
of our common stock even compared to that we might suffer if we were traded on the OTC Bulletin Board.

As a result of the
above, we cannot assure you that our common stock will be listed on a national securities exchange, a national quotation service, the OTC Bulletin Board or the Pink Sheets; or if it is to be listed, whether or not there would be an interruption in
the trading of our common stock. We believe that the listing of our stock on a recognized national trading market, such as the NASDAQ, is an important part of our business and strategy. Such a listing helps our stockholders by providing a readily
available trading market with current quotations. Without that, stockholders may have a difficult time getting a quote for the sale or purchase of our stock, the sale or purchase of our stock would likely be made more difficult and the trading
volume and liquidity of our stock would likely decline. The absence of such a listing may adversely affect the acceptance of our common stock as currency or the value accorded it by other parties. In that regard, listing on a recognized national
trading market will also affect the companys ability to benefit from the use of its operations and expansion plans, including for use in licensing agreements, joint ventures, the development of strategic relationships and acquisitions, which
are critical to our business and strategy and none of which is currently the subject of any agreement, arrangement or understanding, with respect to any future financing or strategic relationship it may undertake. The delisting from NASDAQ would
result in negative publicity and would negatively impact our ability to raise capital in the future.

If we were
delisted from the NASDAQ, we may become subject to the trading complications experienced by Penny Stocks in the over-the-counter market.

Delisting from the NASDAQ may depress the price of our common stock such that we may become a penny stock. The SEC generally defines a penny stock as an equity security that has a market price of less
than $5.00 per share or an exercise price of less than $5.00 per share, subject to specific exemptions. The market price of our common stock is currently less than $5.00 per share. Penny Stock rules require, among other things, that any
broker engaging in a purchase or sale of our securities provide its customers with: (i) a risk disclosure document, (ii) disclosure of market quotations, if any, (iii) disclosure of the compensation of the broker and its salespersons
in the transaction and (iv) monthly account statements showing the market values of our securities held in the customers accounts.



23



---

A broker would be required to provide the bid and offer quotations and compensation
information before effecting the transaction. This information must be contained on the customers confirmation. Generally, brokers are less willing to effect transactions in penny stocks due to these additional delivery requirements. These
requirements may make it more difficult for stockholders to purchase or sell our common stock. Because the broker, not us, prepares this information, we would not be able to assure that such information is accurate, complete or current.

The market price of our common stock has fluctuated widely in the past, and is likely to continue to fluctuate widely based on a
number of factors, many of which are beyond our control.

The market price of our common stock has been, and is likely
to continue to be, highly volatile. Furthermore, the stock market and the market for stocks of relatively small biopharmaceutical companies like ours have from time to time experienced, and likely will again experience, significant price and volume
fluctuations that are unrelated to actual operating performance.

From time to time, stock market analysts publish research
reports or otherwise comment upon our business and future prospects. Due to a number of factors, we may fail to meet the expectations of securities analysts or investors and our stock price would likely decline as a result. These factors include:



| |  |  | announcements by us, our current collaboration partner, any future alliance partners or our competitors of pre-clinical studies and clinical trial
results, regulatory developments, technological innovations or new therapeutic products, product sales, new products or product candidates and product development timelines;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the formation or termination of corporate alliances;
| | - |  | ----------------------------------------------------



| |  |  | developments in patent or other proprietary rights by us or our respective competitors, including litigation;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | developments or disputes concerning our patent or other proprietary rights, and the issuance of patents in our field of business to others;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | government regulatory action;
| | - |  | -----------------------------



| |  |  | period-to-period fluctuations in the results of our operations; and
| | - |  | -------------------------------------------------------------------



| |  |  | developments and market conditions for emerging growth companies and biopharmaceutical companies, in general.
| | - |  | -------------------------------------------------------------------------------------------------------------

In addition, Internet chat rooms have provided forums where investors make predictions about our business and prospects,
oftentimes without any real basis in fact, that readers may trade on.

In the past, following periods of volatility in the
market prices of the securities of companies in our industry, securities class action litigation has often been instituted against those companies. If we face such litigation in the future, it would result in substantial costs and a diversion of
managements attention and resources, which could negatively impact our business.

At August 23, 2011, we had
75,469,911 shares of common stock outstanding 6,458,725 additional shares reserved for the exercise of outstanding options and restricted stock units and 4,733,293 additional shares of common stock authorized for issuance and remaining to be granted
under our stock option plans.

Our principal stockholder can significantly influence all matters requiring the approval
by our stockholders.

As of June 30, 2011, Dr. Goldenberg, our Chairman and Chief Scientific Officer and
Chief Medical Officer, together with certain members of his family, including Ms. Cynthia L. Sullivan, our President and Chief Executive Officer, who is Dr. Goldenbergs wife, and other affiliates, controlled the right to vote
approximately



24



---

11% of our fully diluted common stock. As a result of this voting power, Dr. Goldenberg has the ability to significantly influence the outcome of substantially all matters that may be put to
a vote of our stockholders, including the election of our directors.

We have adopted anti-takeover provisions that may
frustrate any unsolicited attempt to acquire our company or remove or replace our directors and executive officers.

Provisions of our certificate of incorporation, our by-laws and Delaware corporate law could make it more difficult for a third party to
acquire control of our company in a transaction not approved by our Board of Directors. For example, we have adopted a stockholder rights plan that makes it more difficult for a third party to acquire control of our company without the support of
our Board of Directors. In addition, our Board of Directors may issue up to ten million shares of preferred stock and determine the price, rights, preferences and privileges, including voting and conversion rights, of these shares without any
further vote or action by our stockholders. The issuance of preferred stock could have the effect of delaying, deterring or preventing an unsolicited change in control of our company, or could impose various procedural and other requirements that
could make it more difficult for holders of our common stock to effect certain corporate actions, including the replacement of incumbent directors and the completion of transactions opposed by the incumbent Board of Directors. The rights of the
holders of our common stock would be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future.

We are also subject to Section 203 of the Delaware General Corporation Law, or DGCL, which prohibits us from engaging in a business combination with any interested stockholder (as defined
in Section 203 of the DGCL) for a period of three years from the date the person became an interested stockholder, unless certain conditions are met.

There are limitations on the liability of our directors, and we may have to indemnify our officers and directors in certain instances.

Our certificate of incorporation limits, to the maximum extent permitted under Delaware law, the personal liability of our directors for
monetary damages for breach of their fiduciary duties as directors. Our bylaws provide that we will indemnify our officers and directors and may indemnify our employees and other agents to the fullest extent permitted by law. These provisions may be
in some respects broader than the specific indemnification provisions under Delaware law. The indemnification provisions may require us, among other things, to indemnify such officers and directors against certain liabilities that may arise by
reason of their status or service as directors or officers (other than liabilities arising from willful misconduct of a culpable nature), to advance their expenses incurred as a result of any proceeding against them as to which they could be
indemnified and to obtain directors and officers insurance. Section 145 of the DGCL provides that a corporation may indemnify a director, officer, employee or agent made or threatened to be made a party to an action by reason of the
fact that he or she was a director, officer, employee or agent of the corporation or was serving at the request of the corporation, against expenses actually and reasonably incurred in connection with such action if he or she acted in good faith and
in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Delaware law
does not permit a corporation to eliminate a directors duty of care and the provisions of our certificate of incorporation have no effect on the availability of equitable remedies, such as injunction or rescission, for a directors breach
of the duty of care.

We believe that our limitation of officer and director liability assists us to attract and retain
qualified employees and directors. However, in the event an officer, a director or the board of directors commits an act that may legally be indemnified under Delaware law, we will be responsible to pay for such officer(s) or director(s) legal
defense and potentially any damages resulting therefrom. Furthermore, the limitation on director liability may reduce the likelihood of derivative litigation against directors and may discourage or deter stockholders from instituting litigation
against directors for breach of their fiduciary duties, even though such an action, if successful, might benefit our stockholders and us. Given the difficult environment and potential for incurring



25



---

liabilities currently facing directors of publicly-held corporations, we believe that director indemnification is in our and our stockholders best interests because it enhances our ability
to attract and retain highly qualified directors and reduce a possible deterrent to entrepreneurial decision-making.

Nevertheless, limitations of director liability may be viewed as limiting the rights of stockholders, and the broad scope of the
indemnification provisions contained in our certificate of incorporation and bylaws could result in increased expenses. Our board of directors believes, however, that these provisions will provide a better balancing of the legal obligations of, and
protections for, directors and will contribute positively to the quality and stability of our corporate governance. Our board of directors has concluded that the benefit to stockholders of improved corporate governance outweighs any possible adverse
effects on stockholders of reducing the exposure of directors to liability and broadened indemnification rights.

We are
exposed to potential risks from legislation requiring companies to evaluate controls under Section 404 of the Sarbanes-Oxley Act.

The Sarbanes-Oxley Act requires that we maintain effective internal controls over financial reporting and disclosure controls and procedures. Among other things, we must perform system and process
evaluation and testing of our internal controls over financial reporting to allow management to report on, and our independent registered public accounting firm to attest to, our internal controls over financial reporting, as required by
Section 404 of the Sarbanes-Oxley Act. Compliance with Section 404 requires substantial accounting expense and significant management efforts. Our testing, or the subsequent review by our independent registered public accounting firm, may
reveal deficiencies in our internal controls that would require us to remediate in a timely manner so as to be able to comply with the requirements of Section 404 each year. If we are not able to comply with the requirements of Section 404
in a timely manner each year, we could be subject to sanctions or investigations by the SEC, the NASDAQ GMS or other regulatory authorities that would require additional financial and management resources and could adversely affect the market price
of our common stock.

We do not intend to pay dividends on our common stock. Until such time as we pay cash dividends
our stockholders must rely on increases in our stock price for appreciation.

We have never declared or paid dividends
on our common stock. We intend to retain future earnings to develop and commercialize our products and therefore we do not intend to pay cash dividends in the foreseeable future. Until such time as we determine to pay cash dividends on our common
stock, our stockholders must rely on increases in our common stocks market price for appreciation.

At August 23,
2011, we had 75,469,911 shares of common stock outstanding, 6,458,725 additional shares reserved for the exercise of outstanding options and restricted stock units and 4,733,293 additional shares of common stock authorized for issuance and remaining
to be granted under our stock option plan.

Our headquarters is located at 300 American Road, Morris Plains, New Jersey 07950, where we lease approximately 85,000 square feet of commercial office space. In June 2009, we amended the lease agreement
to add an additional 11,000 square feet of commercial office space to lease the entire facility, which we took occupancy on April 1, 2011. On February 11, 2011, we extended the lease facility for an additional ten years, expiring in
October 2031. The current base annual rate is $0.8 million, which is a fixed rate through October 2016 and increases thereafter every five years. Our manufacturing, regulatory, medical, research and development laboratories, and our finance,
marketing and executive offices are currently located in this facility.

We have subleased approximately 1,400 square feet to CMMI for their operations. We operate a 7,500 square-foot, manufacturing facility within our Morris Plains headquarters, which consists of
four independent antibody manufacturing suites, several support areas, and a quality control laboratory. See Item 1 Business, Manufacturing. In addition, our European subsidiary, Immunomedics GmbH, leases executive office space in
Darmstadt, Germany.



|Item 3. | Legal Proceedings
|------- | -----------------

Former Investment Advisor/BrokerAuction Rate Securities Matter

On April 15, 2009, we initiated an arbitration proceeding before the Financial Industry Regulatory Authority (FINRA) against our former investment advisor/broker, Banc of America
Investment Services, Inc. and Banc of America Securities, LLC. In the arbitration, we claim that the respondents violated the New Jersey Uniform Securities Law, the North Carolina Securities Act, and certain FINRA rules by, among other things,
making false representations and/or material omissions concerning auction rate securities, or ARS, inappropriately advising investment in ARS, and failing to supervise their employees. We continue to seek relief pursuant to the New Jersey Uniform
Securities Law and the North Carolina Securities Act for the difference between the par value of our ARS and the amount we received when we sold the ARS on the secondary market, ($2.9 million). Also, we continue to seek consequential damages,
punitive damages, and other relief. The FINRA arbitration hearing in this matter began in September 2010 and is scheduled to resume in September 2011.

Other than as set forth above, the Companys management knows of no other material existing or pending legal proceedings or claims against the Company, nor is the Company involved as a plaintiff in
any material proceeding or pending litigation. To the Companys knowledge, no director, officer or affiliate of the Company, and no owner of record or beneficial owner of more than five percent (5%) of the Companys securities,
or any associate of any such director, officer or security holder is a party adverse to the Company or has a material interest adverse to the Company in reference to pending litigation.

The SEC encourages companies to disclose forward-looking information so that investors can better understand a companys future
prospects and make informed investment decisions. This Annual Report on Form 10-K contains such forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements may be made directly
in this Annual Report, and they may also be made a part of this Annual Report by reference to other documents filed with the Securities and Exchange Commission, or SEC, which is known as incorporation by reference.

Words such as may, anticipate, estimate, expects, projects,
intends, plans, believes and words and terms of similar substance used in connection with any discussion of future operating or financial performance, are intended to identify forward-looking statements. All
forward-looking statements are managements present expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking
statements. These risks and uncertainties include, among other things: our inability to further identify, develop and achieve commercial success for new products and technologies; the possibility of delays in the research and development necessary
to select drug development candidates and delays in clinical trials; the risk that clinical trials may not result in marketable products; the risk that we may be unable to obtain additional capital through strategic collaborations, licensing,
convertible debt securities or equity financing in order to continue our research and development programs as well as secure regulatory approval of and market our drug candidates; our dependence upon pharmaceutical and biotechnology collaborations;
the levels and timing of payments under our collaborative agreements; uncertainties about our ability to obtain new corporate collaborations and acquire new technologies on satisfactory terms, if at all; the development of competing products; our
ability to protect our proprietary technologies; patent-infringement claims; and risks of new, changing and competitive technologies and regulations in the United States and internationally. Please also see the discussion of risks and uncertainties
under Item 1A. Risk Factors Factors That May Affect Our Business and Results of Operations in this Annual Report on Form 10-K.

In light of these assumptions, risks and uncertainties, the results and events discussed in the forward-looking statements contained in this Annual Report or Form 10-K or in any document incorporated by
reference might not occur. Stockholders are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this Annual Report or Form 10-K or the date of the document incorporated by reference in this

section.

Overview

We are a biopharmaceutical company primarily 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, cytokines or
toxins, in each case to create highly targeted agents. Using these technologies, we have built a broad pipeline of therapeutic product candidates that utilize several different mechanisms of action. We have also been one of the first companies to
test antibody combinations as a possibly improved method of cancer therapy, and as a result have also embarked on the development of bispecific (bifunctional) monoclonal antibodies targeting two distinct antigens on the same cancer cells. We believe
that our portfolio of intellectual property, which includes approximately 179 active patents in the U.S. and more than 400 other issued patents worldwide, protects our product candidates and technologies.

We have continued to transition our focus away from the development and commercialization of diagnostic imaging products in order to
accelerate the development of our therapeutic product candidates, although we



31



---

manufacture and commercialize our LeukoScan® product in
territories where regulatory approvals have previously been granted. LeukoScan is indicated for diagnostic imaging for determining the location and extent of infection/inflammation in bone in patients with suspected osteomyelitis, including patients
with diabetic foot ulcers.

From inception in 1982 through June 30, 2011, we had an accumulated deficit of approximately
$217.9 million. In the absence of increased revenues from the sale of current or future products and licensing activities (the amount, timing, nature or source of which cannot be predicted), our losses will continue as we conduct our research and
development activities. These activities are budgeted to expand over time and will require further resources if we are to be successful. As a result, our operating losses are likely to be substantial over the next several years.

The development and commercialization of successful therapeutic products is subject to numerous risks and uncertainties including,
without limitation, the following:



| |  |  | the type of therapeutic compound under investigation and nature of the disease in connection with which the compound is being studied;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability, as well as the ability of our partners, to conduct and complete clinical trials on a timely basis;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | the time required for us to comply with all applicable federal, state and foreign legal requirements, including, without limitation, our receipt of the
necessary approvals of the U.S. Food and Drug Administration, or FDA;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the financial resources available to us during any particular period; and
| | - |  | -------------------------------------------------------------------------



| |  |  | many other factors associated with the commercial development of therapeutic products outside of our control. (See Risk Factors under Item 1A in
this Annual Report on Form 10-K for other factors.)
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Critical Accounting Policies

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S., which require
management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ
from these estimates. The following discussion highlights what we believe to be the critical accounting policies and judgments made in the preparation of these consolidated financial statements.

Revenue Recognition

We have accounted for revenue arrangements that include multiple deliverables as a separate unit of accounting if: a) the delivered item has value to the customer on a standalone basis, b) there is
objective and reliable evidence of the fair value of the undelivered items and c) if the right of return exists, delivery of the undelivered items is considered probable and substantially in the control of the vendor. If these criteria are not met,
the revenue elements must be considered a single unit of accounting for purposes of revenue recognition. We have concluded that the License and Collaboration Agreement dated July 11, 2008, or the Nycomed Agreement, with Nycomed GmbH, and the
Development, Collaboration and License Agreement dated May 9, 2006 with UCB, S.A., or the UCB Agreement, should be accounted for as a single unit of accounting. In October 2009, the Financial Accounting Standards Board issued Accounting
Standards Update ASU 2009-13Multiple-Deliverable Revenue Arrangements, which replaced the concept of allocating revenue consideration amongst deliverables in a multiple-element revenue arrangement according to the fair value with an allocation
based on selling price. Effective July 1, 2010, we applied ASU 2009-13 to our revenue arrangements containing multiple deliverables that were entered into or which significantly modified existing arrangements, of which there were



32



---

none. We will allocate revenue consideration, excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement
containing multiple deliverables. Selling prices are determined using fair value, when available, or our estimate of selling price when fair value is not available for a given unit of accounting. The adoption did not result in a material change in
either the units of accounting or a change in the pattern or timing of revenue recognition since we have not entered into any new arrangements nor have we had significant modifications to our existing arrangements.

We amortized the $40.0 million payment received as part of the Nycomed Agreement over the expected obligation period, which was
originally estimated to be December 2009. During the 2010 fiscal year, this amortization period was changed to March 2010, when all obligations under this agreement were completed.

We also concluded that the $38.0 million payment received from UCB should be amortized over the expected obligation period of the UCB
Agreement. During the first quarter of the 2010 fiscal year, we were relieved by UCB of our remaining obligation to provide UCB with any further supplies. We, therefore, amortized the remainder of the upfront payment of $31.1 million received from
UCB as revenue in the first quarter of the 2010 fiscal year.

In order to determine the revenue recognition for contingent
milestones, we evaluate the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (FASB) guidance on the milestone method of revenue recognition at the inception of a collaboration agreement. The criteria
requires that (i) we determine if the milestone is commensurate with either our performance to achieve the milestone or the enhancement of value resulting from our activities to achieve the milestone, (ii) the milestone be related to past
performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent milestones can be considered as substantive milestones and will be
recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements. During the 2011 and 2010 fiscal years, we recorded revenues in both
years of $10.0 million for milestone payments under the terms of the Nycomed Agreement.

Contract revenue from collaborative
research agreements is recorded when earned based on the performance requirements of the contract. Revenue from non-refundable upfront license fees and certain guaranteed payments where we continue involvement through collaborative development are
deferred and recognized as revenue over the period of continuing involvement. We estimate the period of continuing involvement based on the best available evidential matter available to us at each reporting period. If our estimated time frame for
continuing involvement changes, this change in estimate could impact the amount of revenue recognized in future periods.

Research and development costs that are reimbursable under collaboration agreements are recognized as a reduction of research and
development expenses. We record these reimbursements as a reduction of research and development expenses as our partner in the collaboration agreement has the financial risks and responsibility for conducting these research and development
activities.

Revenue from product sales is recorded when there is persuasive evidence that an arrangement exists, delivery has
occurred, the price is fixed and determinable and collectability is reasonably assured. Allowances, if any, are established for uncollectible amounts based on historical trends, estimated product returns and discounts. Since allowances are recorded
based on managements estimates, actual amounts may be different in the future.

Auction Rate Securities

We held a number of interest bearing auction rate securities, or ARS, that represent investments in pools of assets.
These ARS investments were intended to provide liquidity via an auction process that resets the applicable interest rate at predetermined calendar intervals, allowing investors to either roll over their holdings or gain immediate liquidity by
selling such interests at par. ARS have long-term scheduled maturities, but have



33



---

interest rates that are typically reset at pre-determined intervals (every 28 days for the securities purchased by us), at which time the securities can typically be purchased or sold,
creating a liquid market. In an active market for such investments, the rate reset for each instrument is an opportunity to accept the reset rate or sell the instrument at its face value in order to seek an alternative investment. In the past, the
auction process had allowed investors to roll over their holdings or obtain immediate liquidity by selling the securities at par. The auctions failed during fiscal 2008 and have not settled in an active market since that time. The uncertainties in
the credit markets affected our holdings in ARS investments as the auctions for these securities had failed to settle on their respective settlement dates.

As a result of our assessment of a number of factors, including without limitation, market conditions and the credit quality of these securities, we determined that the estimated fair value did not
approximate par value, although we continued to earn interest on our ARS at the maximum contractual rate. Utilizing a discounted cash flow model we determined that the change in the estimated fair value of our remaining investments in ARS for the
year ended June 30 2009 resulted in other than temporary impairment charge of $2.4 million which was recorded as other expense in the Consolidated Statement of Operations. We recorded an unrealized gain on ARS of $0.2 million for the year ended
June 30, 2010 which was recorded as part of the consolidated statement of comprehensive income. During the 2010 and 2009 fiscal years we used a discounted cash flow model to determine the estimated fair value of our investment in ARS. During
the 2011 fiscal year we sold our remaining ARS.

The ARS that were held were AAA rated collateralized by student loans,
guaranteed by the U.S. Government under the Federal Family Education Loan Program and backed by insurance companies. During the 2011, 2010 and 2009 fiscal years we sold the remaining ARS to brokers in a secondary market that resulted in
realized gains of $0.5 million, $0.9 million and $0.1 million, respectively. We no longer have any investments in ARS.

Foreign Currency Risks

For subsidiaries outside of the United States that operate in a local currency environment, income and expense items are translated to United States dollars at the monthly average rates of exchange
prevailing during the year, assets and liabilities are translated at the period-end exchange rates, and equity accounts are translated at historical exchange rates. Translation adjustments are accumulated in a separate component of
stockholders equity and are included in the determination of comprehensive loss. Transaction gains and losses are included in the determination of net (loss) income.

Stock Based Compensation

We currently have an Employee Share Option
Plan, or the Plan, which permits the grant of share options and shares to our employees for up to 8 million shares of common stock. A summary of this plan is provided in Note 7 to the consolidated financial statements. We believe that such
awards better align the interests of our employees with those of our shareholders. Option awards are generally granted with an exercise price equal to the market price of our stock at the date of grant; those option awards generally vest based on
four years of continuous service and have seven year contractual terms. Certain options provide for accelerated vesting if there is a change in control (as defined in the Plan).

The fair value of each option granted during the years ended June 30, 2011, 2010 and 2009 is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average assumptions in the following table:



|                                |  |                      |  |                |  |

The weighted average fair value at the date of grant for options granted during the years
ended June 30, 2011, 2010 and 2009 were $2.53, $2.59 and $1.88 per share, respectively. We used historical data to estimate forfeitures. The expected term of options granted represents the period of time that options granted are expected to be
outstanding. Expected stock price volatility was calculated on ten-year daily stock trading history. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

We have a total of 1,727,578 shares underlying non-vested options and restricted stock grants outstanding as of June 30,
2011. As of June 30, 2011 and 2010, there was $3.4 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is being recognized over a weighted-average period
of 2.68 years. The weighted average remaining contractual terms of the exercisable shares is 3.09 years and 3.62 years as of June 30, 2011 and 2010, respectively.

Reimbursement of Research & Development Costs

Research and
development costs that are reimbursable under collaboration agreements are included as a reduction of research and development expenses. We record these reimbursements as a reduction of research and development expenses as our partner in the
collaboration agreement has the financial risks and responsibility for conducting these research and development activities.

Impairment of Assets

We review our long-lived assets for impairment, when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of possible
impairment is based upon our judgment of our ability to recover the asset from the expected future undiscounted cash flows of the related operations. Actual future cash flows may be greater or less than estimated. Based on our review, we believe
there is no impairment at June 30, 2011.

Life Insurance Policies

The Company has various life insurance policies on Dr. Goldenberg, which are for the benefit of the Company. When the Company is the
beneficiary of the policy, and there are no other contractual arrangements between the Company and Dr. Goldenberg, the Company recognizes the amount that could be realized under the insurance arrangement as an asset in the balance sheet.

Results of Operations

Fiscal Year 2011 compared to Fiscal Year 2010

Revenues for the
fiscal year ended June 30, 2011 were $14.7 million as compared to $60.9 million for the fiscal year ended June 30, 2010, representing a decrease of $46.2 million or 76%. The current fiscal year does not reflect any license fee revenues
from either the UCB Agreement or the Nycomed Agreement, which had amounted to $31.1 million and $14.5 million, respectively, for the 2010 fiscal year. In August 2009, we received notice from UCB relieving us of our responsibilities for the
manufacturing of epratuzumab, the only remaining obligation under the UCB agreement, thus allowing us to record as revenue the full amount of the remaining deferred license fee revenue. In March 2010, we had completed amortization of the remaining
upfront fees deferred under the Nycomed Agreement. During both the 2011 and 2010 fiscal years we recognized as revenue the receipt of $10.0 million for milestone payments under the terms of the Nycomed Agreement. Product sales for the year ended
June 30, 2011 were $3.6 million, as compared to $3.1 million for the same period in 2010, representing an increase of $0.5 million or 16% due primarily to higher sales volume of LeukoScan in Europe over the previous year. Research and
development revenues for the year ended June 30, 2011 were $1.0 million as compared to $2.1 million for the same period in 2010, a decrease of $1.1 million or 52% due to the timing and size of the grant programs in the current year.

Total operating expenses for the fiscal year ended June 30, 2011
were $33.7 million as compared to $27.0 million in the fiscal year ended June 30, 2010, representing an increase of $6.7 million or 25%. Research and development expenses for the fiscal year ended June 30, 2011 increased by $5.5 million,
or 28%, to $25.4 million from $19.9 million in fiscal year ended June 30, 2010 due primarily to a $4.8 million decrease of research and development expense reimbursement, $0.9 million of higher spending for clinical trials, and $0.5 million for
higher patent-related expenses, partially offset by reduced materials and lab supplies. Reimbursement of research and development expenses for the 2011 fiscal year declined to approximately $2.0 million compared to $6.8 million in fiscal 2010 and is
expected to continue to decline subsequent to June 30, 2011. Cost of goods sold for fiscal year ended June 30, 2011 decreased by $0.6 million or 56% to $0.4 million from $1.0 million in fiscal year ended June 30, 2010. During the
year-ended June 30, 2010, cost of goods sold increased $0.6 million as a result of the inventory reserve on certain of our Leukoscan® work-in-process inventories which were deemed to be unsaleable due to a third-party manufacturers process deviation that resulted in product that did not meet
our quality control standards. Excluding the impact of an inventory reserve adjustment for work-in-process, gross profit margins were 89% for the year ended June 30, 2010 compared to 88% for the year ended June 30, 2011.

Sales and marketing expenses remained unchanged at $0.8 million for both the 2011 and 2010 fiscal years. General and administrative
expenses for fiscal year 2011 increased by $1.8 million or 33% from $5.4 million in fiscal year 2010 to $7.1 million in fiscal year 2011. This increase is primarily attributable to increased legal expenses of $2.0 million pertaining primarily to the
FINRA arbitration hearing related to our ARS and other legal matters, as well as increased employee related costs of $0.2 million. This was partially offset by the recognition in fiscal year 2010 of $0.7 million of additional incentive compensation
to our Chairman in accordance with his employment agreement, resulting from our profitability for the 2010 fiscal year.

On
October 29, 2010, we received notification from the Department of the Treasury that we had been awarded a total cash grant of approximately $2.9 million under the QTDP program administered under Section 48D of the Internal Revenue Code, of
which approximately $2.5 million relates to qualifying expenses we had previously incurred during the 2010 fiscal year and the cash was received during the second quarter of fiscal 2011. The remainder of the grant of approximately $0.4 million was
received during the first quarter of fiscal 2012 based on qualifying expenses we had incurred during the 2011 fiscal year. We recognized the full $2.9 million of the grant as of the date of notification since we had already incurred all of the
qualifying expenses.

A gain of $0.5 million was reported for the year ended June 30, 2011 on the sales and redemptions
of ARS with a carrying value of $9.0 million (par value of $11.0 million), as compared to a $0.9 million gain on the sale of ARS that had a carrying value of $9.0 million (par value of $11.3 million) for the same period in 2010. See discussion in
Note 3 to the consolidated financial statements for more information on our investments in auction rate securities.

Interest
and other income of $0.5 million for the year ended June 30, 2011 decreased by $0.3 million from $0.8 million for the same period in 2010. This decline was primarily the result of lower rates of return on investments and lower cash balances
during the 2011 fiscal year. This decline for the 2011 fiscal year included the lower level of the amortization of the discount for the ARS of $0.1 million as compared to $0.5 million for the previous fiscal year.

For the 2010 fiscal year, we recorded a tax benefit of $1.0 million as a result of our sale of approximately $12.8 million of New Jersey
state net operating losses or NOLs. There were no comparable sales of NOLs in fiscal 2011. For both the 2011 and 2010 fiscal years we recorded a Federal income tax provision of $0.1 million. The 2010 fiscal year provision was offset by a
Federal tax refund received for the fiscal year 2007 alternative minimum tax paid, (as provided by the Federal Troubled Asset Relief Program). In addition, for the fiscal year 2010 we recorded a $0.2 million reduction of tax obligations of our
foreign subsidiaries. For the 2011 fiscal year, we recorded a $50,000 tax provision for our foreign subsidiaries.

Net (loss)
allocable to Immunomedics, Inc. common stockholders for fiscal year 2011 is $(15.1) million, or $(0.20) per share as compared to net income of $37.0 million, or $0.49 per share, in fiscal year 2010.

Fiscal Year 2010 compared to Fiscal Year 2009

Revenues for the fiscal year ended June 30, 2010 were $60.9 million as compared to $30.0 million for the fiscal year ended
June 30, 2009, representing an increase of $30.9 million or 103%. The increase for the year ended June 30, 2010 is primarily the result of recording license fee revenue of $31.1 million for the UCB Agreement. There was no corresponding
revenue for UCB in 2009. In August 2009, we received notice from UCB relieving us of our responsibilities for the manufacturing of epratuzumab, the only remaining obligation under the UCB agreement, thus allowing us to record the full amount of the
remaining deferred license fee revenue. Product sales for the year ended June 30, 2010 were $3.1 million, as compared to $3.5 million for the same period in 2009, representing a decrease of $0.4 million or 11% due to lower sales volume of
LeukoScan in Europe over the previous year. Research and development revenues for the year ended June 30, 2010 were $2.1 million as compared to $1.0 million for the same period of 2009, an increase of $1.1 million or 110% due to the timing and
size of the grant programs in the current year.

Total operating expenses for the fiscal year ended
June 30, 2010 were $27.0 million as compared to $27.5 million in the fiscal year ended June 30, 2009, representing a decrease of $0.5 million or 2%. Research and development expenses for the fiscal year ended June 30, 2010 decreased
by $1.6 million, or 7%, to $19.9 million from $21.5 million in fiscal year ended June 30, 2009 due primarily to $4.2 million of increased expense reimbursement from Nycomed (which did not continue at the same level in fiscal 2011) and $1.2
million of lower patent-related expenses, partially offset by $2.0 million of higher levels of materials, supplies and testing for Nycomed related production, $1.0 million of higher spending for clinical trials as well as $0.5 million from higher
headcount and related salaries and employee benefits. Cost of goods sold for fiscal year ended June 30, 2010 increased by $0.7 million or 233% to $1.0 million from $0.3 million in fiscal year ended June 30, 2009. During the year-ended
June 30, 2010, cost of goods sold increased $0.6 million as a result of the inventory reserve on certain of our
Leukoscan® work-in-process inventories which were deemed to be unsaleable due to a third-party
manufacturers process deviation that resulted in product that did not meet our quality control standards. Excluding the impact of the inventory reserve adjustment for work-in-process, the gross profit margins were 89% for the year-ended
June 30, 2010 compared to 92% for the year ended June 30, 2009. The decline in the gross profit percentage in fiscal year 2010 was primarily due to lower sales volume and unfavorable currency impact.

Sales and marketing expenses for the 2010 and 2009 fiscal years were $0.8 million. General and administrative expenses for fiscal year
2010 increased by $0.4 million or 8% from $5.0 million in fiscal year 2009 to $5.4 million in fiscal year 2010. This increase is primarily attributable to an increase of $0.4 million in additional incentive compensation due to Dr. David M.
Goldenberg in accordance with his employment agreement.

A gain of $0.9 million was reported for the year ended June 30,
2010 on the sales and redemptions of ARS with a carrying value of $9.0 million (par value of $11.3 million), as compared to a $2.4 million temporary impairment charge on marketable securities associated with our investments in auction rate
securities for the year ended June 30, 2009, partially offset by a $69,000 gain on the settlement of ARS. See discussion in Note 3 to the consolidated financial statements for more information on our investments in auction rate securities.

Interest and other income decreased by $0.4 million from $1.2 million in fiscal year 2009 to $0.8 million in fiscal year
2010. This decline was primarily the result of lower rates of return on investments and lower cash balances during the year. This decline in fiscal year 2010 was partially offset by an increase of $77,000 for the amortization of the discount for the
auction rate securities over the previous year.

For fiscal years 2010 and 2009, we recorded a tax benefit of $1.0 million and
$1.4 million, respectively, as a result of our sale of approximately $12.8 million and $17.2 million of New Jersey state net operating losses, respectively. For the fiscal year 2010, we recorded a Federal income tax provision of $0.1 million, which
was offset by a similar Federal tax refund received for the fiscal year 2007 alternative minimum tax paid, (as

provided by the Federal Troubled Asset Relief Program). In addition, for the fiscal year 2010 we recorded a $0.2 million reduction of tax obligations of our foreign subsidiaries. For the fiscal
year 2009, we recorded a Federal income tax provision of $0.2 million and our foreign subsidiaries recorded a foreign tax provision of $0.3 million.

Net income allocable to Immunomedics, Inc. common stockholders for fiscal year 2010 is $37.0 million, or $0.49 per share as compared to $2.3 million, or $0.03 per share, in fiscal year 2009.

Research and Development Expenses

Research and development expenses for our product candidates in development were $25.4 million for the fiscal year ended June 30, 2011, $19.9 million for the fiscal year ended June 30, 2010 and
$21.5 million for the fiscal year ended June 30, 2009. Research and development expenses increased by $5.5 million in fiscal year 2011, or 28%, as compared to fiscal 2010. Research and development expenses decreased by $1.6 million in fiscal
2010, or 7%, as compared to fiscal 2009.

We do not track expenses on the basis of each individual compound under
investigation or through clinical trials and therefore we do not provide a breakdown of such historical information in that format. We evaluate projects under development from an operational perspective, including such factors as results of
individual compounds from laboratory/animal testing, patient results and enrollment statistics in clinical trials. It is important to note that multiple product candidates are often tested simultaneously. It is not possible to calculate each
antibodys supply costs. There are many different development processes and test methods that examine multiple product candidates at the same time. We have, historically, tracked our costs in the categories discussed below, specifically
research costs and product development costs and by the types of costs outlined below.

Our research
costs consists of outside costs associated with animal studies and costs associated with research and testing of our product candidates prior to reaching the clinical stage. Such research costs primarily include personnel costs, facilities,
including depreciation, lab supplies, funding of outside contracted research and license fees. Our product development costs consist of costs from preclinical development (including manufacturing), conducting and administering clinical trials and
patent expenses.

The following table sets forth a breakdown of our research and development expenses by those associated with
research and those associated with product development for the periods indicated.

Research Costs

Research costs decreased by $0.5 million or 7% for the year ended June 30, 2011 compared to 2010. Research costs increased by $0.6 million or 10% for the year ended June 30, 2010 compared to
2009. The changes in research costs primarily relate to the following:

Personnel costs were $2.7 million for both 2011 and
2010, with salary increases in 2011 offset by employee turnover. Personnel costs in 2010 were $2.7 million, an increase of $0.1 million or 3% as compared to 2009 due primarily to salary increases.

---

The use of outside research and testing services in 2011 was $0.2 million, a decrease of
$0.3 million or 60% compared to 2010. This decrease was primarily the result of outside research and testing procedures that were unnecessary for 2011. The use of outside research and testing services in 2010 were $0.5 million, a decrease of $0.1
million or 17% compared to 2009. This decrease resulted from the level of spending for outside services that was not required from Federal grant program activities that were necessary in the previous year.

Lab supplies and chemical reagent costs were $0.7 million in both 2011 and in 2010. Lab supplies and chemical reagent costs were $0.7
million in 2010, an increase of $0.1 million or 17% from 2009. This increase was a result of the increased level of activities from the previous year.

Indirect administrative and support services that are allocated to research based on research spending levels decreased by $0.4 million or 29% to $1.0 million in fiscal year 2011, primarily resulting from
the decline of research spending as compared to product development spending, resulting in a lower allocation percentage of general and administrative costs. Indirect administrative and support services that are allocated to research based on
research spending levels increased by $0.3 million or 27% to $1.4 million in fiscal year 2010 as compared to 2009, primarily resulting from employee related costs.

Product Development Costs

Product development costs for the year
ended June 30, 2011 in total increased by $6.0 million or 45% as compared to 2010. Product development costs for the year ended June 30, 2010 in total decreased by $2.2 million or 14% as compared to 2009. The changes in product development
costs primarily relate to the following:

In 2011, 2010 and 2009 the Company has benefited from cost efficiencies realized on
labor and overhead as a result of continued efforts on the development of veltuzumab for Nycomed, for which the Company has been reimbursed. In fiscal 2011 the level of reimbursement received from Nycomed declined $4.8 million from $6.8 million
received in 2010 to $2.0 million received in 2011. For fiscal 2010 the Company received $4.2 million of reimbursed product manufacturing expenses higher than the $2.6 million that was received in the fiscal year 2009. The Company does not expect the
reimbursement from Nycomed for 2012 to continue at the 2011 level.

Clinical trial expenses in fiscal year 2011 were $2.8
million, an increase of $0.9 million or 47% over 2010, a result of increased patient enrollment for clivatuzumab tetraxetan (hPAM4) and milatuzumab clinical trials. Clinical trial expenses in fiscal year 2010 were $1.9 million, an increase of
$1.0 million or 111% over 2009, a result of the increased patient enrollment in clinical trials in 2010, primarily for the clivatuzumab tetraxetan (hPAM4) trials.

Personnel costs in 2011 were $6.2 million, an increase of $0.4 million or 7% as compared to 2010, primarily due to salary increases and higher staffing levels. Personnel costs in 2010 were $5.8 million,
an increase of $0.4 million or 7% as compared to 2009, primarily due to salary increases and higher staffing levels.

Patent
expenses for 2011 were $2.0 million, an increase of $0.5 million or 33% from 2010. This increase was the result of higher professional fees incurred for patent litigation defense. Patent expenses for 2010 were $1.5 million, a reduction of $1.2
million or 44% from 2009. This reduction was primarily due to the completion of patent related expenses for legal actions during the 2010 fiscal year, resulting in lower professional fees.

Lab supplies and chemical reagent costs were $2.0 million in 2011, a decrease of $0.5 million or 20% over 2010. This reduction was
primarily the result of reduced levels of production of veltuzumab as requested by Nycomed, partially offset by higher levels of clinical trial participation. Lab supplies and chemical reagent costs were $2.5 million in 2010, an increase of $0.7
million or 39% over 2009. The increase in 2010 was primarily due to manufacturing development requirements for veltuzumab product as part of the Nycomed Agreement and increased requirements to higher levels of clinical trial participation.

---

Expenses for outside testing were $0.9 million in 2011, a decrease of $0.2 million or 18%
from 2010. This decline was primarily the result of reduced testing involving Nycomed related production. Expenses for outside testing were $1.1 million in 2010, an increase of $0.6 million or 120% from 2009. This increase was the result of
increased testing for process validations and product safety testing for Nycomed related manufacturing.

Indirect
administrative and support services that are allocated to development based on development spending levels increased by $0.2 million or 8% to $2.7 million in fiscal year 2011, primarily resulting from increased product development spending,
resulting in a higher allocation percentage of general and administrative costs. Indirect administrative and support services that are allocated to development based on development spending levels increased by $0.2 million or 9% to $2.5 million in
fiscal year 2010, primarily resulting from employee related costs.

Completion of clinical trials may take several years or
more. The length of time varies according to the type, complexity and the disease indication of the product candidate. We estimate that clinical trials of the type we generally conduct are typically completed over the following periods:

|Phase III      |  |                           | 2-5 Years | 

The duration and cost of clinical trials through each of the clinical phases may vary significantly over
the life of a particular project as a result of, among other things, the following factors:



| |  |  | the length of time required to recruit qualified patients for clinical trials;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the duration of patient follow-up in light of trials results;
| | - |  | -------------------------------------------------------------



| |  |  | the number of clinical sites required for trials; and
| | - |  | -----------------------------------------------------



| |  |  | the number of patients that ultimately participate.

Liquidity and Capital Resources

Since its inception in 1982,
Immunomedics principal sources of funds have been the private and public sale of debt and equity securities and revenues from licensing. There can be no assurance that Immunomedics will be able to raise the additional capital it will need to
complete its pipeline of research and development programs, on commercially acceptable terms, if at all. If the Company were unable to raise capital on acceptable terms, its ability to continue its business would be materially and adversely
affected.

Discussion of Cash Flows

Cash flows from operating activities.Net cash used in operating activities for the year ended June 30, 2011 was $11.9
million, compared to cash used in operations of $7.1 million for the year ended June 30, 2010. The increase in the current years cash flow used for operations is primarily the result of higher research and development expenses as a result
of the reduced level of research and development expense reimbursements and increased legal and clinical trial expense levels.

For fiscal 2010, net cash used in operating activities was $7.1 million as compared to $21.3 million provided by operations for fiscal
2009. This decline in the cash flow provided by operations was primarily the result of the $40.0 million upfront payment from the signing of the Nycomed Agreement that occurred in fiscal year 2009 resulting in positive cash flow from operations that
year. This decline is partially offset by the receipt of $10.0 million milestone payments earned from the Nycomed Agreement in fiscal 2010.

Cash flows from investing activities.Net cash provided by investing activities was
$9.2 million for both the 2011 and 2010 fiscal years. In fiscal year 2011, $9.5 million was received from the sales of certain auction rate securities and $0.3 million was received from the proceeds of an insurance claim, which were partially offset
by $0.6 million for capital expenditures. In fiscal year 2010, $9.9 million of proceeds were received from the sales and redemptions of certain auction rate securities, which were partially offset by $0.7 million of capital expenditures. In fiscal
year 2009, proceeds of $0.7 million were received from the redemptions of certain auction rate securities, offset by $0.6 million of capital expenditures.

Cash flows from financing activities.Net cash provided by financing activities for the year ended June 30, 2011 was $0.2 million, resulting from the exercise of employee stock options. For
fiscal year ended June 30, 2010, $26,000 was provided by financing activities, which was comprised of $0.2 million from the exercise of stock options, offset by the settlement of 47,000 employee stock options for $0.1 million.

At June 30, 2011, we had a working capital of $24.7 million, representing a decrease of $3.9 million from the $28.6 million working
capital at June 30, 2010. This decline in working capital was caused by $11.9 million of cash used in operations offset in part by $8.2 million in proceeds received from the sale of non-current auction rate securities.

At June 30, 2010, we had a working capital of $28.6 million, representing an increase of $48.8 million from the $20.2 million
working capital deficit at June 30, 2009. This increase in working capital in fiscal 2010 was primarily a result of the recognition in fiscal year 2010 of $45.7 million of deferred revenue from the UCB and Nycomed Agreements which were
classified as current liabilities as of June 30, 2009 and the cash proceeds from the sales and redemptions of $9.9 million of auction rate securities during the 2010 fiscal year. Partially offsetting this increase in working capital was our use
of cash in operations of $7.1 million during the year.

Our cash and cash equivalents of $27.1 million at June 30, 2011
represented a decrease of $2.4 million from $29.5 million at June 30, 2010. The decline for fiscal year 2011 was primarily attributable to our use of cash in operations, partially offset by the sales and redemptions of $9.9 million of certain
ARS. Our cash and cash equivalents of $29.5 million at June 30, 2010 represented an increase of $2.1 million from $27.4 million at June 30, 2009. The increase for fiscal year 2010 was primarily attributable to the sales and redemptions of
$9.9 million of certain ARS, partially offset by our use of cash in operations.

Other Liquidity Matters

We have $27.1 million of unrestricted cash and cash equivalents at June 30, 2011. Based on our expected cash
utilization rate, we believe we have sufficient funds to continue our operations and research and development programs for at least the next twelve months. During fiscal 2012, cash expenditures for our current research and development programs will
be at a higher level than in fiscal year 2011 due to increased spending for research and development, lower reimbursement from Nycomed and increased clinical trial activities, while a number of new clinical studies are supported by the Company and
our corporate partners, offset in part by lower legal and professional fees. We are also evaluating plans to initiate a Phase III registration trial of veltuzumab in non-Hodgkins lymphoma and a Phase III registration trial of clivatuzumab in
pancreatic cancer. We will need to secure additional funding to advance veltuzumab and clivatuzumab into these Phase III trials.

We expect research and development activities to continue to expand over time and we do not believe we will have adequate cash to complete our research and development compounds in our development
pipeline in line with our corporate strategy. As a result, we will continue to require additional financial resources in order to continue our research and development programs, clinical trials of product candidates and regulatory filings. Our
ability to raise capital through public and private debt or equity financings may be negatively impacted by the recent downturn in the economy. There can be no assurances that financing will be available when we need it on terms acceptable to us, if
at all.



41



---

We continue to evaluate various programs to raise additional capital and to seek additional
revenues from the licensing of our proprietary technologies. There can be no assurance that we will be able to raise the additional capital we will need on commercially acceptable terms, if at all. If we are unable to raise capital on acceptable
terms, our ability to continue our business would be materially and adversely affected. At the present time, we are unable to determine whether any of these future activities will be successful and, if so, the terms and timing of any definitive
agreements.

Actual results could differ materially from our expectations as a result of a number of risks and uncertainties,
including the risks described in Item 1A Risk Factors, Factors That May Affect Our Business and Results of Operations, and elsewhere in this Annual Report on Form 10-K. Our working capital and working capital requirements are
affected by numerous factors and such factors may have a negative impact on our liquidity. Principal among these are the success of product commercialization and marketing products, the technological advantages and pricing of our products, the
impact of the regulatory requirements applicable to us, and access to capital markets that can provide us with the resources when necessary to fund our strategic priorities.

Contractual Commitments

Our major contractual obligations relate to
an operating lease for our facility and employment contracts in effect for our Chairman of the Board, Chief Medical Officer and Chief Scientific Officer and the President/Chief Executive Officer. We have identified and quantified the significant
commitments in the following table for the fiscal years ending June 30:

rate of $0.8 million, which has a fixed rate through October 2015 and increases thereafter every five years. The lease amendments included an additional 11,000 square feet, enabling us to lease the entire facility.

|(2) | Included are amounts due under employment contracts with David M. Goldenberg, our Chief Medical Officer and Chief Scientific Officer, through 2016 and Cynthia Sullivan,
our President and Chief Executive Officer through 2014. The five-year employment contract with David M. Goldenberg was entered into effective July 1, 2011. This contract also included a minimum royalty agreement, a percentage of the
consideration the Company receives from licensing agreements, sales of intellectual properties and disposition of undeveloped assets, as disclosed in the employment agreement. The amounts included above are only the minimum payments and do not
include possible adjustments to existing salaries, additional incentive compensation or potential bonus payments as set forth in the employment contract.

Recently Issued Accounting Pronouncements

In October 2009, the Financial
Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU 2009-13Multiple-Deliverable Revenue Arrangements (ASU 2009-13). ASU 2009-13 amends Accounting Standards Codification, or ASC 605-25Revenue
RecognitionMultiple-Element Arrangements. The update replaces the concept of allocating revenue consideration amongst deliverables in a multiple-element revenue arrangement according to fair value with an allocation based on selling price. ASU
2009-13 also establishes a hierarchy for determining the selling price of revenue deliverables sold in multiple element revenue arrangements. The selling price used for each deliverable will be based on vendor-specific objective evidence, or VSOE if
available, third-party evidence if VSOE is not available, or managements estimate of an elements



42



---

stand-alone selling price if neither VSOE nor third-party evidence is available. The amendments in this update also require an allocation of selling price amongst deliverables be performed based
upon each deliverables relative selling price to total revenue consideration, rather than on the residual method previously permitted. We prospectively adopted ASU 2009-13 on July 1, 2010. We will apply ASU 2009-13 to our revenue
arrangements containing multiple deliverables that were entered into or significantly modified on or after July 1, 2010, of which there were none. We will allocate revenue consideration, excluding contingent consideration, based on the relative
selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Selling prices are determined using fair value, when available, or our estimate of selling price when fair value is not available
for a given unit of accounting. The adoption did not result in a material change in either the units of accounting or a change in the pattern or timing of revenue recognition since we have not entered into any new arrangements nor have we had
significant modifications to our existing arrangements.

In June 2011, the FASB issued ASU 2011-05, an amendment of the
Codification Topic 220, Comprehensive Income, or ASU 2011-05. ASU 2011-05 increases the prominence of items reported in other comprehensive income and facilitates convergence of GAAP and International Financial Reporting Standards by eliminating the
option to present components of other comprehensive income as part of the statement of changes in stockholders equity. ASU 2011-05 requires that all nonowner changes in stockholders equity be presented either in a single continuous
statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present: (i) each component of net income along with total net income; (ii) each component of other comprehensive
income along with a total for other comprehensive income; and (iii) a total amount for comprehensive income. In the two-statement approach, an entity is required to present components of net income and total net income in the statement of net
income. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive
income. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the entity is required to present on the face of the financial statements
reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. ASU 2011-05 does not
change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 does not change the option for an entity to present components of other comprehensive
income either net of related tax effects or before related tax effects, and the tax effect for each component must be disclosed in the notes to the financial statements or presented in the statement in which other comprehensive income is presented.
ASU 2011-05 does not affect how earnings per share is calculated or presented. ASU 2011-05 will be effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011, with earlier adoption
permitted. The new guidance will be effective for us beginning July 1, 2012 and will have presentation changes only.

In
January 2010, the FASB issued ASC Update No. 2010-06 Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements which updated guidance to amend the disclosure requirements related to
recurring and nonrecurring fair value measurements. This update requires new disclosures on significant transfers of assets and liabilities between Level 1 and Level 2 of the fair value hierarchy (including the reasons for these transfers) and the
reasons for any transfers in or out of Level 3. This update also requires a reconciliation of recurring Level 3 measurements about purchases, sales, issuances and settlements on a gross basis.

In addition to these new disclosure requirements, this update clarifies certain existing disclosure requirements. For example, this
update clarifies that reporting entities are required to provide fair value measurement disclosures for each class of assets and liabilities rather than each major category of assets and liabilities. This update also clarifies the requirement for
entities to disclose information about both the valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. This update will become effective for us with the interim and annual reporting period beginning
January 1, 2011, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which



43



---

will become effective for us with the interim and annual reporting period beginning January 1, 2012. We will not be required to provide the amended disclosures for any previous periods
presented for comparative purposes. Other than requiring additional disclosures, adoption of this update will not have a material effect on our financial statements.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

The following discussion about our exposure to market risk of financial instruments contains forward-looking statements under the Private
Securities Litigation Reform Act of 1995. Actual results may differ materially from those described due to a number of factors, including uncertainties associated with general economic conditions and conditions impacting our industry.

We have not entered into and do not expect to enter into, financial instruments for trading or hedging purposes. We do not currently
anticipate entering into interest rate swaps and/or similar instruments. One of our primary market risk exposure with regard to financial instruments is to changes in interest rates, which would impact interest income earned on such instruments. A
one percent change (100 basis points) in interest rates on our investments would have impacted interest income by a nominal amount for the year ended June 30, 2011.

We also may be exposed to fluctuations in foreign currencies in regards to certain agreements with service providers relating to certain clinical trials that are in process. Depending on the strengthening
or weakening of the U.S. dollar, realized and unrealized currency fluctuations could be significant.

Report of Independent Registered Public Accounting Firm

The Board of Directors and
Stockholders

Immunomedics, Inc.

We have audited the accompanying consolidated balance sheets of Immunomedics, Inc. and subsidiaries as of June 30, 2011 and 2010, and the related consolidated statements of operations and
comprehensive (loss) income, stockholders equity (deficit) and cash flows for each of the three years in the period ended June 30, 2011. Our audits also included the financial statement schedule listed in the Index at Item 15(a).
These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all
material respects, the consolidated financial position of Immunomedics, Inc. and subsidiaries at June 30, 2011 and 2010, and the consolidated results of their operations and their cash flows for each of the three years in the period ended
June 30, 2011, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related consolidated financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with
the standards of the Public Company Accounting Oversight Board (United States), Immunomedics, Inc.s internal control over financial reporting as of June 30, 2011, based on criteria established in Internal Control Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated August 24, 2011 expressed an unqualified opinion thereon.

IMMUNOMEDICS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Business Overview

Immunomedics, Inc., a Delaware corporation (Immunomedics or the Company) is
a biopharmaceutical company focused on the development of monoclonal antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases. The Company has continued to transition its focus away from the development and
commercialization of diagnostic imaging products in order to accelerate the development of its therapeutic product candidates, although the Company manufactures and commercializes its LeukoScan® product in territories where regulatory approvals have previously been granted in Europe, Canada and in certain other markets outside the U.S. LeukoScan is indicated
for diagnostic imaging for determining the location and extent of infection/inflammation in bone in patients with suspected osteomyelitis, including patients with diabetic foot ulcers. The Company has two foreign subsidiaries, Immunomedics B.V. in
the Netherlands and Immunomedics GmbH in Darmstadt, Germany, to assist the Company in managing sales efforts and coordinating clinical trials in Europe. In addition, included in the accompanying financial statements is the majority-owned U.S.
subsidiary, IBC Pharmaceuticals, Inc. (IBC), which has been working since 1999 on the development of novel cancer radiotherapeutics using patented pre-targeting technologies with proprietary, bispecific antibodies.

Immunomedics is subject to significant risks and uncertainties, including, without limitation, our inability to further identify, develop
and achieve commercial success for new products and technologies; the possibility of delays in the research and development necessary to select drug development candidates and delays in clinical trials; the risk that clinical trials may not result
in marketable products; the risk that the Company may be unable to successfully finance and secure regulatory approval of and market its drug candidates; its dependence upon pharmaceutical and biotechnology collaborations; the levels and timing of
payments under its collaborative agreements; uncertainties about the Companys ability to obtain new corporate collaborations and acquire new technologies on satisfactory terms, if at all; the development of competing products; its ability to
protect its proprietary technologies; patent-infringement claims; and risks of new, changing and competitive technologies and regulations in the United States and internationally. For more detail regarding such risks and uncertainties please refer
to Risk Factors in Item 1A.

As of June 30, 2011, the Company had cash and cash equivalents totaling
$27.1 million. Based on the Companys expected cash utilization rate, the Company believes it has sufficient funds to continue its operations and research and development programs for at least the next twelve months. During fiscal 2012, the
Company expects that cash expenditures for its current research and development programs will be at a higher level than in fiscal year 2011 due to increased spending for research and development, lower reimbursement from Nycomed and increased
clinical trial activities, while a number of new clinical studies are supported by the Company and its corporate partners, offset in part by lower legal and professional fees. The Company is evaluating plans to initiate a Phase III registration
trial of veltuzumab in non-Hodgkins lymphoma and a Phase III registration trial of clivatuzumab in pancreatic cancer. The Company will need to secure additional funding to advance veltuzumab and clivatuzumab into these Phase III trials. The
Company does not believe, as currently funded, it will have adequate cash on hand to complete its pipeline of research and development programs in accordance with its corporate strategy. Immunomedics is actively considering financing alternatives to
fund these programs as market conditions permit, potentially through equity or debt financings and through collaborative agreements. The Company continues to evaluate various financing options to raise additional capital and to seek additional
revenues from the licensing of its proprietary technologies.

Since its inception in 1982, Immunomedics principal
sources of funds have been the private and public sale of debt and equity securities and revenues from licensing. There can be no assurance that Immunomedics will be able to raise the additional capital it will need to complete its R&D programs
on commercially acceptable terms, if at all. If the Company were unable to raise capital on acceptable terms, its ability to continue its business would be materially and adversely affected.

2. Summary of Significant Accounting Policies

Principles of Consolidation and Presentation

The consolidated financial statements include the accounts of Immunomedics and its majority-owned subsidiaries. Noncontrolling interests
in consolidated subsidiaries in the consolidated balance sheets represent minority stockholders proportionate share of the equity (deficit) in such subsidiaries. All significant intercompany balances and transactions have been eliminated in
consolidation.

Correction of a Prior Period Error

During the third quarter of fiscal year 2011, the Company corrected an error in its condensed consolidated financial statements regarding
the financial reporting for noncontrolling interests related to its IBC Pharmaceuticals Inc. subsidiary in its consolidated financial statements. Beginning July 1, 2009, the Companys consolidated financial statements did not report the
net loss incurred by noncontrolling interest, which should have been specifically identified in the balance sheet, statement of operations and the statement of changes in stockholders equity. The amounts related to errors identified in the
financial reporting resulted in an immaterial understatement of net income attributable to common stockholders during the fiscal year ended June 30, 2010, and an immaterial overstatement in net loss attributable to common stockholders for the
six month period ended December 31, 2010. Since the Company determined that the errors were not material to the consolidated financial statements in the periods in which they originated or the period in which they were corrected, the Company
recorded the total correction of $0.1 million during the three-month period ended March 31, 2011.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reported period. Actual results could differ from those estimates.

Foreign Currencies

For subsidiaries outside of the United States that operate in a local currency environment, income and expense items are translated to
United States dollars at the monthly average rates of exchange prevailing during the year, assets and liabilities are translated at year-end exchange rates and equity accounts are translated at historical exchange rates. Translation adjustments are
accumulated in a separate component of stockholders equity in the Consolidated Balance Sheets and are included in the determination of comprehensive income (loss) in the Consolidated Statements of Stockholders Equity (Deficit).
Transaction gains and losses are included in the determination of net (loss) income in the Consolidated Statements of Operations. As of June 30, 2011 and 2010, the cumulative unrealized foreign currency translation gain included in other
comprehensive income was approximately $0.4 million and $0.1 million, respectively.

Accounts Receivable

Credit is extended to customers based upon an evaluation of the customers financial condition. Accounts receivable are recorded at
net realizable value. Past due balances are based on contractual terms.

Allowance for Doubtful Accounts

The Company utilizes a specific identification accounts receivable reserve methodology based on a review of outstanding balances and
previous activities to determine the allowance for doubtful accounts. The Company charges off uncollectible receivables at the time the Company determines the receivable is no longer collectible. The Company does not require collateral or other
security to support financial instruments subject to credit risk. The impact on the operating profit (loss) for a one percentage point change in the allowance for doubtful accounts is less than $1,000.

Concentration of Credit Risk

Cash, cash equivalents and marketable securities are financial instruments that potentially subject the Company to concentration of credit
risk. Immunomedics periodically invests its cash in debt instruments of financial institutions and corporations with strong credit ratings. Immunomedics has established guidelines relative to diversification and maturities that are designed to help
ensure safety and liquidity. These guidelines are periodically reviewed to take advantage of trends in yields and interest rates.

Estimated Fair Value of Financial Instruments

The Company has categorized its financial assets, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy as set forth below. The Company does not have any
financial liabilities that are required to be measured at fair value on a recurring basis. If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input
that is significant to the fair value measurement of the instrument.

Financial assets recorded on the consolidated balance
sheets as of June 30, 2011 and 2010 are categorized based on the inputs to the valuation techniques as follows (in thousands):



| |  |  | Level 1Financial assets whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market which
the company has the ability to access at the measurement date (examples include active exchange-traded equity securities and most U.S. Government and agency securities).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2Financial assets whose value are based on quoted market prices in markets where trading occurs infrequently or whose values are
based on quoted price`s of instruments with similar attributes in active markets.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3Financial assets whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant
to the overall fair value measurement. These inputs reflect managements own assumptions about the assumptions a market participant would use in pricing the asset.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Reimbursement of Research and Development Costs

Research and development costs that are reimbursable under collaboration agreements are included as a reduction of research and
development expenses. The Company records these reimbursements as a reduction of research and development expenses as the Companys partner in the collaboration agreement has the financial risks and responsibility for conducting these research
and development activities.

Inventory

Inventory, which consists of the finished product and work in process of LeukoScan, is stated at the lower of average cost (which approximates first-in, first-out) or market, and includes materials, labor
and manufacturing overhead. An inventory reserve is recorded for finished product that is not deemed to be saleable, if necessary. During fiscal 2010, the Company performed and completed its standard quality control testing procedures for certain
batches of LeukoScan work-in-process inventory (total value of $0.6 million). When the results of the quality control testing became available in April 2010, it was determined that due to a third-party manufacturers process deviation the
product did not meet the Companys quality control standards. The Company therefore established an inventory reserve for this specific work-in-process inventory, which was physically discarded by June 30, 2011. There were no inventory
reserves recorded in fiscal year 2011.

Property and Equipment

Property and equipment are stated at cost and are depreciated on a straight-line basis over the estimated useful lives (5-10 years) of the
respective assets. Leasehold improvements are capitalized and amortized over the lesser of the initial life of the lease or the estimated useful life of the asset. Immunomedics reviews long-lived assets for impairment whenever events or changes in
business circumstances occur that indicate that the carrying amount of the assets may not be recoverable. Immunomedics assesses the recoverability of long-lived assets held and to be used based on undiscounted cash flows, and measures the
impairment, if any, using discounted cash flows. To date the Company has not taken any impairment charges on property and equipment.

Revenue Recognition

The Company has accounted for revenue arrangements
that include multiple deliverables as a separate unit of accounting if: a) the delivered item has value to the customer on a standalone basis, b) there is objective and reliable evidence of the fair value of the undelivered items and c) if the right
of return exists, delivery of the



53



---

undelivered items is considered probable and substantially in the control of the vendor. If these criteria are not met, the revenue elements must be considered a single unit of accounting for
purposes of revenue recognition. The Company has concluded that the License and Collaboration Agreement dated July 11, 2008, or the Nycomed Agreement, with Nycomed GmbH, and the Development, Collaboration and License Agreement dated May 9,
2006 with UCB, S.A., or the UCB Agreement, should be accounted for as a single unit of accounting. In October 2009, the Financial Accounting Standards Board issued Accounting Standards Update ASU 2009-13  Multiple-Deliverable Revenue
Arrangements, which replaced the concept of allocating revenue consideration amongst deliverables in a multiple-element revenue arrangement according to the fair value with an allocation based on selling price. Effective July 1, 2010, the
Company applied ASU 2009-13 to its revenue arrangements containing multiple deliverables that were entered into or which significantly modified existing arrangements, of which there were none. The Company will allocate revenue consideration,
excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Selling prices are determined using fair value, when available, or the
Companys estimate of selling price when fair value is not available for a given unit of accounting. The adoption did not result in a material change in either the units of accounting or a change in the pattern or timing of revenue recognition
since the Company has not entered into any new arrangements nor has the Company had significant modifications to its existing arrangements.

The Company amortized the $40.0 million payment received as part of the Nycomed Agreement over the expected obligation period, which was originally estimated to be December 2009. During the 2010 fiscal
year this amortization period was changed to March 2010, when all obligations under this agreement were completed.

The
Company also concluded that the $38.0 million payment received from UCB should be amortized over the expected obligation period of the UCB Agreement, which was initially estimated to end in November 2009. During the first quarter of the 2010 fiscal
year, the Company was relieved by UCB of its remaining obligation to supply UCB with any further supplies. The Company therefore amortized the remainder of the upfront payment of $31.1 million received from UCB as revenue in the first quarter of the
2010 fiscal year.

Payments received under contracts to fund certain research activities are recognized as revenue in the
period in which the research activities are performed. Payments received in advance that are related to future performance are deferred and recognized as revenue when the research projects are performed. Upfront nonrefundable fees associated with
license and development agreements where the Company has continuing involvement in the agreement are recorded as deferred revenue and recognized over the estimated service period. If the estimated service period is subsequently modified, the period
over which the upfront fee is recognized is modified accordingly on a prospective basis.

In order to determine the revenue
recognition for contingent milestones, the Company evaluates the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (FASB) guidance on the milestone method of revenue recognition at the inception of a
collaboration agreement. The criteria requires that (i) the Company determines if the milestone is commensurate with either its performance to achieve the milestone or the enhancement of value resulting from the Companys activities to
achieve the milestone, (ii) the milestone be related to past performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent
milestones can be considered as substantive milestones and will be recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements.
During the 2011 and the 2010 fiscal years, the Company recorded revenues for each year of $10.0 million for milestone payments under the terms of the Nycomed Agreement.

Revenue from the sale of diagnostic products is recorded when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable and collectability is
reasonably assured. Allowances, if any, are established for uncollectible amounts, estimated product returns and discounts.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

The Company uses the asset and liability method to account
for income taxes, including the recognition of deferred tax assets and deferred tax liabilities for the anticipated future tax consequences attributable to differences between financial statements amounts and their respective tax bases. The Company
reviews its deferred tax assets for recovery. A valuation allowance is established when the Company believes that it is more likely than not that its deferred tax assets will not be realized. Changes in valuation allowances from period to period are
included in the Companys tax provision in the period of change.

Benefits received resulting from the sale of the
Companys State of New Jersey net operating losses (NOL) in fiscal years 2010 and 2009 were recognized as a tax benefit when the NOL is approved for sale by the State of New Jersey. There were no sales of NOL in fiscal year 2011.

The Company does not have an accrual for uncertain tax positions as of June 30, 2011 or 2010. The U.S. Federal
statute of limitation remains open for the fiscal years 2006 onward. State income tax returns are generally subject to examination for a period of 3-5 years after filing of the respective return.

Net (Loss) Income Per Share Allocable to Common Stockholders

Basic net (loss) income per share is based upon the number of weighted average number of shares of common stock and vested restricted
shares outstanding. Diluted net income per share is based upon the weighted average number of shares of common stock and dilutive potential shares of common stock outstanding. During fiscal 2011, no potential shares of common stock were included in
the calculation since their affect would be antidilutive due to the operating loss. Potential shares of common stock resulted from the assumed exercise of outstanding stock options, with exercise prices less than the average market price of the
Companys common stock during the years ended June 30, 2010 and 2009, calculated under the treasury stock method.

Comprehensive (Loss) Income

Comprehensive (loss) income consists of net (loss) income, net unrealized (losses) gains on securities available for sale and foreign currency translation adjustments and is presented in the Consolidated
Statements of Operations and Comprehensive (Loss) Income.

Stock-Based Compensation

The Companys 2006 Stock Incentive Plan (the Plan) permits the grant of options and shares to its employees for up to
8 million shares of common stock. A summary of this plan is provided in Note 7. The Company believes that such awards better align the interests of its employees with those of its shareholders. Option awards are generally granted with an
exercise price equal to the market price of the Companys stock at the date of grant; those option awards generally vest based on four years of continuous service and have seven year contractual terms. Certain options provide for accelerated
vesting if there is a change in control (as defined in the Plan).

The fair value of each option granted during the years ended June 30, 2011, 2010 and
2009 is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions in the following table:



|                                |  |                      |  |               |  |

|Expected dividend yield         |  | 0%                   |  | 0%            |  | 0%           
|Expected option term (years)    |  | 5.42                 |  | 5.78          |  | 5.31         
|Expected stock price volatility |  | 88%                  |  | 92%           |  | 92%          
|Risk-free interest rate         |  | 2.33%  2.86%        |  | 2.77%  3.32% |  | 1.92%  3.71%

The weighted average fair value at the date of grant for options granted during the years ended
June 30, 2011, 2010 and 2009 were $2.53, $2.59 and $1.88 per share, respectively. The Company uses historical data to estimate forfeitures. The expected term of options granted represents the period of time that options granted are expected to
be outstanding. Expected stock price volatility was calculated on ten-year daily stock trading history. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of
grant.

The Company has 1,727,578 non-vested options and restricted stock shares outstanding. As of June 30, 2011, 2010
and 2009 there was $3.4 million, $3.4 million and $4.3 million, respectively, of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is being recognized over a
weighted-average period of 2.68 years. The weighted average of remaining contractual terms of the exercisable shares is 3.09 and 3.62 years as of June 30, 2011 and 2010, respectively.

Qualifying Therapeutic Discovery Project Program

On October 29, 2010, the Company was notified that it had been awarded a total cash grant of approximately $2.9 million under the Qualifying Therapeutic Discovery Project program administered under
section 48D of the Internal Revenue Code, of which approximately $2.5 million relates to qualifying expenses the Company had previously incurred during the 2010 fiscal year which was received during the second quarter of fiscal 2011. The remainder
of the grant of approximately $0.4 million will be received during the first quarter of fiscal 2012 based on qualifying expenses the Company has incurred during the 2011 fiscal year. The Company recognized the full $2.9 million of the grant as of
the date of notification since the Company has already incurred all of the qualifying expenses. Since this program is non-recurring in nature, the Company elected to classify this payment as other income in the Condensed Consolidated Statements of
Operations for the year ended June 30, 2011.

Financial Instruments

The carrying amounts of cash and cash equivalents, other current assets and current liabilities approximate fair value due to the
short-term maturity of these instruments. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

In October 2009, the Financial Accounting Standards Board, or FASB issued Accounting Standard Update, or ASU 2009-13  Multiple-Deliverable Revenue Arrangements (ASU 2009-13). ASU 2009-13 amends
Accounting Standards Codification, or ASC 605-25  Revenue Recognition  Multiple-Element Arrangements. The update replaces the concept of allocating revenue consideration amongst deliverables in a multiple-element revenue arrangement
according to fair value with an allocation based on selling price. ASU 2009-13 also establishes a hierarchy for determining the selling price of revenue deliverables sold in multiple element revenue arrangements. The selling price used for each
deliverable will be based on vendor-specific objective evidence, or VSOE if available, third-party evidence if VSOE is not available, or managements



56



---

estimate of an elements stand-alone selling price if neither VSOE nor third-party evidence is available. The amendments in this update also require an allocation of selling price amongst
deliverables be performed based upon each deliverables relative selling price to total revenue consideration, rather than on the residual method previously permitted. The Company prospectively adopted ASU 2009-13 on July 1, 2010. The
Company will apply ASU 2009-13 to its revenue arrangements containing multiple deliverables that were entered into or significantly modified on or after July 1, 2010, of which there were none. The Company will allocate revenue consideration,
excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Selling prices are determined using fair value, when available, or our
estimate of selling price when fair value is not available for a given unit of accounting. The adoption did not result in a material change in either the units of accounting or a change in the pattern or timing of revenue recognition since the
Company has not entered into any new arrangements now has it had significant modifications to its existing agreements.

In
June 2011, the FASB issued ASU 2011-05, an amendment of the Codification Topic 220, Comprehensive Income, or ASU 2011-05. ASU 2011-05 increases the prominence of items reported in other comprehensive income and facilitates convergence of GAAP and
International Financial Reporting Standards by eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders equity. ASU 2011-05 requires that all nonowner changes in
stockholders equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present: (i) each component of net income along with
total net income; (ii) each component of other comprehensive income along with a total for other comprehensive income; and (iii) a total amount for comprehensive income. In the two-statement approach, an entity is required to present
components of net income and total net income in the statement of net income. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for
other comprehensive income, along with a total for comprehensive income. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the entity is required
to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other
comprehensive income are presented. ASU 2011-05 does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 does not change the option
for an entity to present components of other comprehensive income either net of related tax effects or before related tax effects, and the tax effect for each component must be disclosed in the notes to the financial statements or presented in the
statement in which other comprehensive income is presented. ASU 2011-05 does not affect how earnings per share is calculated or presented. ASU 2011-05 will be effective retrospectively for fiscal years, and interim periods within those years,
beginning after December 15, 2011, with earlier adoption permitted. The new guidance will be effective for the Company beginning July 1, 2012 and will have presentation changes only.

In January 2010, the FASB issued ASC Update No. 2010-06 Fair Value Measurements and Disclosures (Topic 820): Improving
Disclosures about Fair Value Measurements which updated guidance to amend the disclosure requirements related to recurring and nonrecurring fair value measurements. This update requires new disclosures on significant transfers of assets and
liabilities between Level 1 and Level 2 of the fair value hierarchy (including the reasons for these transfers) and the reasons for any transfers in or out of Level 3. This update also requires a reconciliation of recurring Level 3 measurements
about purchases, sales, issuances and settlements on a gross basis.

In addition to these new disclosure requirements, this
update clarifies certain existing disclosure requirements. For example, this update clarifies that reporting entities are required to provide fair value measurement disclosures for each class of assets and liabilities rather than each major category
of assets and liabilities. This update also clarifies the requirement for entities to disclose information about both the valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. This update will become
effective for the Company with the interim and annual reporting period beginning January 1, 2011, except for the



57



---

requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which will become effective for the Company with the interim and annual reporting
period beginning January 1, 2012. The Company will not be required to provide the amended disclosures for any previous periods presented for comparative purposes. Other than requiring additional disclosures, adoption of this update will not
have a material effect on the Companys financial statements.

3. Auction Rate Securities

The Companys securities, for which there is not the positive intent and ability to hold to maturity, are classified as
available-for-sale and are carried at fair value. Unrealized holding gains and losses, which are deemed to be temporary, on securities classified as available-for-sale are classified as a separate component of accumulated other comprehensive loss.
Immunomedics considered all of its auction rate securities, or ARS to be available-for-sale. Immunomedics did not hold any ARS at June 30, 2011. ARS at June 30, 2010 consisted of the following as shown below (in thousands):

ARS are debt instruments that represent investments in pools of assets. These ARS investments are
intended to provide liquidity via an auction process that resets the applicable interest rate at predetermined calendar intervals, allowing investors to either roll over their holdings or gain immediate liquidity by selling such interests at par.
ARS that were held had long-term scheduled maturities, ranging from 2032 to 2046, but with interest rates that were typically reset at pre-determined intervals, (every 28 days for the securities purchased by the Company), at which time the
securities would typically be purchased or sold, creating a liquid market. When there was an active market for such investments, the reset rate for each instrument was an opportunity to accept the rates that reset or sell the instrument at its face
value in order to seek an alternative investment. In the past, the auction process has allowed investors to roll over their holdings or obtain immediate liquidity by selling the securities at par. During fiscal 2008 the auctions failed and have not
settled in an active market since that time.

As a result of the Companys assessment of a number of factors, including
without limitation, market conditions and the credit quality of these securities, the Company determined that the estimated fair value of the remaining ARS was less than par value, although the Company continued to earn interest on its ARS at the
maximum contractual rate. The Company used a discounted cash flow model to determine the estimated fair value of its remaining non-current investment in ARS of $11.0 million as of June 30, 2010. Utilizing this discounted cash flow model and the
value of the ARS sold subsequent to June 30, 2010, the Company determined that the change in the estimated fair value of its investments in ARS for the year ended June 30, 2010 resulted in an unrealized gain of $0.2 million which was
reported in the Consolidated Statement of Comprehensive Income. Utilizing the same discounted cash flow model for the year ended June 30, 2009, the Company determined that the estimated fair value of its investments in ARS decreased and
recorded an additional other than temporary impairment charge of $2.4 million to reduce the value of the ARS to their estimated fair value which was recorded as other expense in the Consolidated Statement of Operations.

The ARS held were AAA rated collateralized by student loans guaranteed by the U.S. government under the Federal Family Education Loan
Program and backed by insurance companies. There are no ARS held by the Company as of June 30, 2011.

During the
years ended June 30, 2011, 2010 and 2009, the Company sold or redeemed the ARS for $9.5 million, $9.9 million and $0.7 million, respectively, to brokers in the secondary market, resulting in realized gains of $0.5 million, $0.9 million and $0.1
million, respectively.

7. Stockholders Equity

Preferred Stock

The Certificate of Incorporation of the Company
authorizes 10,000,000 shares of preferred stock, $.01 par value per share. The preferred stock may be issued from time to time in one or more series, with such distinctive serial designations, rights and preferences as shall be determined by the
Board of Directors. For each of the fiscal years ended June 30, 2011, 2010 and 2009 the Company has had no preferred stock outstanding.



59



---

Common Stock

During the years ended June 30, 2010 and 2009, the Company settled 47,000 and 204,000 respectively, employee stock options at the
market price per share at the time of the settlement, for a total settlement value of $0.1 million and $0.2 million, respectively. These settlements were from employees who were exercising their stock options which were available under the 2002
Employee Share Option Plan. Included in the employee group that settled their stock options during the 2009 fiscal year were the Chairman of the Board and the Chief Executive Officer of the Company who elected to settle and receive cash payments
(net of taxes), in lieu of shares of the Companys common stock upon the exercise of their options to purchase 150,000 and 15,000 shares of common stock, respectively. These transactions resulted in net cash payments to the Chairman of the
Board and to the Chief Executive Officer of $74,000 and $7,400, respectively.

Stockholders Rights Plan

In February 2002, the Companys Board of Directors declared a dividend of one new right per share pursuant to the
2002 Stockholder Rights Plan (the 2002 Rights Plan) adopted by the Board of Directors. The 2002 Rights Plan involved the distribution of one Right as a dividend on each outstanding share of the Companys common stock to
each holder of record on March 15, 2002. The 2002 Rights Plan provides that if a third party acquires more than 15% of the Companys common stock without prior approval of the Board of Directors, all of the stockholders of the Company
(other than the acquiring party) will be entitled to buy either shares of a special series of our Preferred Shares, or shares of the Companys common stock with a market value equal to double the Exercise Price for each Right they hold. Under
these circumstances, the Board of Directors may instead allow each such Right (other than those held by the acquiring party) to be exchanged for one share of the Companys common stock. The exercise or exchange of these Rights would have a
substantial dilutive effect on the acquiring party. The Companys Board of Directors retains the right at all times to discontinue the 2002 Rights Plan through redemption of all rights or amend the 2002 Rights Plan in any respect. The Rights
will expire on March 1, 2012 (unless extended or unless the Rights are earlier redeemed by the Company as described in the 2002 Rights Plan). No shareholder has exercised this right as of June 30, 2011.

Stock Incentive Plans

The Immunomedics, Inc. 2006 Stock Incentive Plan (2006 Stock Incentive Plan) was created with the intention to promote the interests of the Company, by providing eligible persons with the
opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Company as an incentive to remain with the organization. Under the plan there are 12,000,000 shares of common stock authorized for issuance,
which was comprised of 6,736,625 shares of common stock previously available under the 2002 Employee Share Option Plan (the 2002 Plan) and an additional 5,263,375 shares of common stock.

The 2006 Stock Incentive Plan is divided into three separate equity incentive programs. These incentive programs consist of:



| |  |  | Discretionary Grant Program under which eligible persons may be granted options to purchase shares of common stock or stock appreciation rights tied to
the value of the common stock;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock Issuance Program under which eligible persons may be issued shares of common stock pursuant to restricted stock awards, restricted stock shares,
performance shares or other stock-based awards which vest upon completion of a designated service period or the attainment of pre-established performance milestones, or such shares of common stock may be a fully-vested bonus for services rendered;
and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Automatic Grant Program under which eligible non-employee Board members will automatically receive grants at designated intervals over their period of
continued Board service.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company believes that such awards better align the interests of its employees
with those of its shareholders. Option awards are generally granted with an exercise price equal to the market price of the



60



---

Companys stock at the date of grant; those option awards generally vest based on four years of continuous service and have seven year contractual terms. Certain options provide for
accelerated vesting if there is a change in control (as defined in the Plan). At June 30, 2011, 4,578,293 stock options were still available for future grant and shares of common stock were reserved for possible future issuance upon exercise of
stock options both currently outstanding and which may be issued in the future.

Each of the Companys outside Directors
who had been a Director prior to July 1st of each year is granted, at the annual shareholder meeting of each year, an option to purchase shares of the Companys common stock at fair market value on the grant date, the number of options to
be issued is at the discretion of the Companys Board of Directors. For fiscal years 2011, 2010 and 2009 stock options to purchase 80,000 (including 25,000 of restricted stock), 104,167 (including 29,167 of restricted stock) and 75,000
(including 25,000 of restricted stock), respectively, were granted to these Directors. When an outside Director is elected to the Board of Directors, they are awarded options for 20,000 shares of the Companys common stock.

Information concerning options for the years ended June 30, 2011, 2010 and 2009 is summarized as follows:

8. Earnings Per Share

Basic earnings per share are calculated using the weighted average number of outstanding shares of common stock including vested restricted shares. Diluted earnings per share computations, as calculated
under the treasury stock method, include the weighted average number of shares of additional outstanding common stock issuable for stock options and restricted stock whether or not currently exercisable. Diluted earnings per share for the periods
presented do not include securities if their effect was antidilutive.

For fiscal years 2010 and 2009, the Company recorded a state tax benefit of $1.0 million and $1.4
million, respectively, as a result of its sale of approximately $12.8 million and $17.2 million, of New Jersey State NOL, respectively. There were no sales of NOL for fiscal year 2011.

A valuation allowance is provided when it is more likely than not that some portion or all
of the deferred tax assets will not be realized. The valuation allowances for fiscal years 2011 and 2010 have been applied to offset the deferred tax assets in recognition of the uncertainty that such tax benefits will be realized as the Company
continues to incur losses. The differences between book income and tax income primarily relate to the recognition of income resulting from depreciation and stock compensation expenses.

At June 30, 2011, the Company has available net operating loss carry forwards for federal income tax reporting purposes of
approximately $179.5 million and for state income tax reporting purposes of approximately $38.3 million, which expire at various dates between fiscal 2011 and 2029. Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended, the
annual utilization of a companys net operating loss and research credit carry forwards may be limited if the Company experiences a change in ownership of more than 50 percentage points within a three-year period. As a result of certain
financing arrangements, the Company may have experienced such ownership changes. Accordingly, the Companys net operating loss carry forwards available to offset future federal taxable income arising before such ownership changes may be
limited. Similarly, the Company may be restricted in using its research credit carry forwards arising before such ownership changes to offset future federal income tax expense. Of the deferred tax asset valuation allowance related to the net
operating loss carry forwards, approximately $22.3 million relates to a tax deduction for non-qualified stock options.

At
June 30, 2011, the Company did not have any material unrecognized tax benefits and the Company does not anticipate that its unrecognized tax benefits will significantly change in the next twelve months. The Company will recognize potential
interest and penalties related to income tax positions as a component of the provision for income taxes on the consolidated statements of operations in any future periods in which the Company must record a liability. The Company is no longer subject
to federal, state, or foreign income tax assessments for years prior to 2009.

10. Related Party Transactions

Certain of the Companys affiliates, including members of its senior management and Board of Directors, as well as their respective
family members and other affiliates, have relationships and agreements among themselves as well as with the Company and its affiliates, that create the potential for both real, as well as perceived, conflicts of interest. These include
Dr. David M. Goldenberg, the Companys Chairman, Chief Medical Officer and Chief Scientific Officer, Ms. Cynthia L. Sullivan, the President and Chief Executive Officer, who is the wife of Dr. David M. Goldenberg,
and certain companies with which the Company does business, including the Center for Molecular Medicine and Immunology (CMMI) and IBC Pharmaceuticals, Inc.

Dr. David M. Goldenberg

Dr. David M. Goldenberg
was an original founder of Immunomedics in 1982 and continues to play a critical role in its business. He currently serves as Chairman of the Board of Directors, Chief Medical Officer and Chief Scientific Officer, and is married to our President and
Chief Executive Officer, Cynthia L. Sullivan. Dr. Goldenberg is a party to a number of agreements with the Company involving not only his services, but intellectual property owned by him. In addition, Dr. Goldenberg performs services for
The Center for Molecular Medicine and Immunology, a not-for-profit specialized cancer research center.

License Agreement.

Pursuant to a License Agreement between Immunomedics and Dr. Goldenberg, certain patent applications owned by
Dr. Goldenberg were licensed to Immunomedics at the time of Immunomedics formation in exchange for a royalty in the amount of 0.5% of the first $20.0 million of annual net sales of all products covered by any of such patents and 0.25% of
annual net sales of such products in excess of $20.0 million. Five of the licensed U.S. patents have since expired. In November 1993 the ownership rights of Immunomedics were extended as part of Dr. Goldenbergs employment agreement, with
Immunomedics agreeing to diligently pursue all ideas, discoveries, developments and products, into the entire medical field, which, at any time during his past or

continuing employment by Immunomedics (but not when performing services for CMMI  see below), Dr. Goldenberg has made or conceived or hereafter makes or conceives, or the making or
conception of which he has materially contributed to or hereafter contributes to, all as defined in the Employment Agreement.

Employment Agreement.

On December 17, 2008, the Company entered into the Second Amended and Restated Employment Agreement (effective beginning July 1, 2007 with the previous employment agreement) with
Dr. Goldenberg for his service to the Company as the Chief Scientific Officer and Chief Medical Officer (the Goldenberg Agreement), which terminated June 30, 2011. The Goldenberg Agreement covered aspects of his compensation as
well as duties and responsibilities of his employment at Immunomedics. Under the Goldenberg Agreement, Dr. Goldenbergs annual base salary was a minimum of $500,000, which was reviewed annually for appropriate increases by the Board of
Directors of the Company. Dr. Goldenberg was also eligible to participate in any Companys incentive compensation plan in place for its senior level executives and was eligible to receive an annual discretionary bonus based upon certain
performance standards to be determined by the Compensation Committee. Dr. Goldenbergs annual bonus target was 30% of his annual base salary, subject to achievement of performance goals, with a potential payout from 0 to 150% of the target
amount. Dr. Goldenberg will also be eligible to receive equity compensation awards under the Companys 2006 Stock Incentive Plan, at the discretion of the Compensation Committee. On July 1, 2011, the Company entered into the Third
Amended and Restated Employment Agreement with Dr. Goldenberg, (see Note 15 below).

Dr. Goldenberg is also eligible
to receive certain additional incentive compensation during the agreement term. Beginning with the 2008 fiscal year, for any fiscal year in which the Company records an annual net loss, Dr. Goldenberg shall receive a sum equal to 0.75% of the
consideration the Company receives from any licensing agreement, sale of intellectual property or similar transaction with any third party, with certain exceptions as defined in the Goldenberg Agreement. For any fiscal year in which the Company
records net income, Dr. Goldenberg shall receive a sum equal to 1.50% of the Companys Annual Net Revenue as defined in the Goldenberg Agreement for each such fiscal year, and thereafter throughout the non-competition period, as described
in the Agreement.

Dr. Goldenberg is also eligible to receive royalty payments on royalties received by the Company. For
each fiscal year the Company shall pay Dr. Goldenberg a sum equal to a percentage of the annual royalties the Company receives on each of the products for which Dr. Goldenberg is an Inventor, and all products using, related to or derived
from products for which Dr. Goldenberg is an Inventor. The percentage of royalties that the Company will pay to Dr. Goldenberg on each patented product will be determined based on the percentage of royalties that the Company must pay to
external third parties.

Dr. Goldenberg is also eligible to receive minimum payments of $150,000 to Dr. Goldenberg
during each of the fiscal years, payable in equal quarterly payments, as an advance against the amounts due as additional incentive compensation, royalty payments and dispositions of undeveloped assets. In the event the Company completes a
disposition of the Companys undeveloped assets for which Dr. Goldenberg was an Inventor, the Company will pay Dr. Goldenberg a sum equal to at least twenty percent or more of the consideration the Company receives from each
disposition. The Companys obligation to compensate Dr. Goldenberg upon dispositions of undeveloped assets applies to all dispositions completed within the contract term or within three years thereafter.

In accordance with the terms of the Goldenberg Agreement, additional compensation of $0.9 million and $0.4 million was earned by
Dr. Goldenberg for the fiscal years ended June 30, 2010 and 2009, respectively as a result of the Companys profitability for those fiscal years. For the 2011 fiscal year the minimum payments received by Dr. Goldenberg under the
employment agreement was $150,000.

Finally, it is a condition to his employment agreement that Dr. Goldenberg be
permitted to continue his involvement with CMMI, as discussed in greater detail below. Dr. Goldenberg also is compensated by IBC Pharmaceuticals as discussed in greater detail in these notes to the Consolidated Financial Statements.

Cynthia L. Sullivan

On December 31, 2006, the Company and Cynthia L. Sullivan entered into an Amended and Restated Employment Agreement pertaining to
Ms. Sullivans service as the Companys President and Chief Executive Officer. On December 17, 2008, the Company and Ms. Sullivan entered into the Second Amended and Restated Employment Agreement (the Sullivan
Agreement) in order to comply with Section 409A of the Internal Revenue Code, which changed the income tax treatment of nonqualified deferred compensation and imposed new requirements on both the terms and operation of such compensation.
On June 15, 2010, the Company and Ms. Sullivan entered into the Third Amended and Restated Employment Agreement (the Amended Sullivan Agreement).

The Amended Sullivan Agreement, terminated on December 31, 2010, was automatically extended for up to a one-year period. Ms. Sullivan is also eligible to participate in the Companys
incentive compensation plan in place for its senior level executives. In addition, Ms. Sullivan will be eligible to receive an annual discretionary bonus determined by the Compensation Committee of the Board based upon certain performance
standards to be determined by the Compensation Committee. Under the Amended Sullivan Agreement, Ms. Sullivans annual bonus target was 30% of her annual base salary, subject to achievement of performance goals, with a potential payout from
0 to 150% of the target amount. Ms. Sullivan also is eligible to receive equity compensation awards under the Companys 2006 Stock Incentive Plan, or any such successor equity compensation plan as may be in place from time to time. On
July 1, 2011, the Company entered into the Fourth Amended and Restated Employment Agreement with Ms. Sullivan, see Note 15 below.

Relationships with The Center for Molecular Medicine and Immunology

The Companys product development has involved, to varying degrees, CMMI, for the performance of certain basic research and patient
evaluations, the results of which are made available to the Company pursuant to a collaborative research and license agreement. CMMI, which is funded primarily by grants from the National Cancer Institute (NCI), was located in Belleville, New
Jersey. The Company subleases approximately 1,400 square feet of the Immunomedics Morris Plains facility to CMMI. Dr. Goldenberg is the founder, current President and a member of the Board of Trustees of CMMI. Dr. Goldenbergs
employment agreement permits him to devote such time as is necessary to fulfill his duties to the CMMI and IBC Pharmaceuticals, Inc, provided that such duties do not materially interfere with his ability to perform any of his obligations under the
Goldenberg Agreement. Certain of the Companys consultants have employment relationships with CMMI, and Dr. Hans Hansen, the Companys emeritus executive officer, is an adjunct member of CMMI. Despite these relationships, the Company
believes CMMI is independent of Immunomedics, and CMMIs management and fiscal operations are the responsibility of CMMIs Board of Trustees.

The Company has reimbursed CMMI for expenses incurred on behalf of the Company, including amounts incurred pursuant to research contracts, in the amount of approximately $0.3 million, $0.4 million and
$0.3 million during the years ended June 30, 2011, 2010 and 2009, respectively. In fiscal years ended June 30, 2011, 2010 and 2009 the Company incurred $61,000, $49,000 and $29,000, respectively, of legal expenses for patent related
matters for patents licensed to Immunomedics from CMMI. The Company may decide whether or not to support them. However, any inventions made independently of the Company at CMMI are the property of CMMI.

License Agreements

Nycomed GmbH

On July 11, 2008, the Company entered into a License and Collaboration Agreement (the Nycomed Agreement) with Nycomed
GmbH (Nycomed) providing Nycomed a worldwide license to develop, manufacture and commercialize veltuzumab, the Companys humanized anti-CD20 antibody, veltuzumab in the subcutaneous formulation, for the treatment of all non-cancer
indications. The Company retains the rights to develop, manufacture and commercialize veltuzumab in the field of oncology.

Under the terms of the Nycomed Agreement, Immunomedics received a non-refundable initial cash payment of $40.0 million on August 21,
2008. Immunomedics could also receive up to $580.0 million in regulatory and sales potential cash milestone payments, based on the successful development of veltuzumab by Nycomed and the achievement of specified product sales thresholds. These
potential milestone payments include clinical development and regulatory filings ($97.0 million), regulatory approvals ($123.0 million) to be achieved in Europe ($37.0 million), the U.S. ($75.0 million) and Japan ($11.0 million), and up to $360.0
million associated with the achievement of certain sales thresholds. The Company could also receive an escalating double digit royalty based on annual net sales, if any, by Nycomed, its affiliates or sublicenses under the Nycomed Agreement during
the royalty term. During each of the 2011 and the 2010 fiscal years, the Company received $10.0 million payments as a result of Nycomed achieving certain clinical milestones under the terms of the Nycomed Agreement. No other clinical milestones or
royalty payments were achieved. There can be no assurance that the other clinical, regulatory or sales milestones will be achieved and therefore there can be no assurance that the Company will receive any future payments.

As the Company had continuing obligations under the Nycomed Agreement, the Company initially recorded the $40.0 million non-refundable
payment as deferred revenue. The Company amortized to revenue this non-refundable payment as it fulfilled its obligations under the Nycomed Agreement, which was completed in March 2010. The Company recognized as License Fee Revenue $14.5 million and
$25.5 million for the years ended June 30, 2010 and 2009, respectively.

Nycomed is solely responsible for the development, manufacturing and commercialization of
veltuzumab, for the subcutaneous formulation, for all non-cancer indications. The Companys major obligations were to complete the research and development activities as specified in the Nycomed Agreement and to manufacture and supply
veltuzumab to Nycomed for the quantity of materials for the period of time specified in the Nycomed Agreement. The Company completed its manufacturing and supply obligations and its responsibilities in the Phase I/II study in ITP during the
2010 fiscal year.

For the years ended June 30, 2011, 2010 and 2009, the Company has received reimbursements for
manufactured materials requested by Nycomed aggregating $1.7 million, $6.3 million and $2.5 million, respectively, as outlined in the Nycomed Agreement. The Company does not expect the reimbursement from Nycomed for fiscal 2012 to continue at the
fiscal 2011 level.

UCB, S.A.

On May 9, 2006, the Company entered into an agreement with UCB, S.A., the UCB Agreement, providing UCB an exclusive worldwide license to develop, manufacture, market and sell epratuzumab for the
treatment of all autoimmune disease indications. Under the terms of the UCB Agreement, the Company received from UCB a non-refundable cash payment totaling $38.0 million. The Company recorded the $38.0 million non-refundable payment as deferred
revenue and was to amortize the $38.0 million payment received over the expected obligation period, originally estimated to end in November 2009.

In addition to the upfront payment, the Company is entitled to receive up to $145.0 million in cash payments and $20.0 million in equity investments in milestone payments contingent on regulatory
approvals based on the successful development of epratuzumab by UCB and is entitled to receive up to $135.0 million related to the achievement of specified product sales thresholds. These potential milestone payments of $165.0 million relate for
regulatory approvals to be achieved in Europe ($40.0 million), the U.S. ($60.0 million) and Japan ($20.0 million) and up to $45.0 million for potential regulatory approvals for autoimmune disease indications not in clinical trials at the time of the
UCB Agreement. The Company will also receive product royalties based upon a percentage of aggregate annual net sales under the UCB Agreement during the product royalty term, which percentage is subject to reduction under certain circumstances. No
clinical milestones or royalty payments were achieved through June 30, 2011. There can be no assurance that these regulatory or sales achievements will be met and therefore there can be no assurance that the Company will receive such future
payments.

During the 2007 fiscal year, UCB decided to stop further new patient enrollment into the Systemic Lupus
Erythematosus, or SLE, clinical trials designed and initiated by the Company. During the 2008 fiscal year, UCB established new protocols under which new clinical trials for the treatment of SLE would be conducted and subsequently terminated the then
existing SLE clinical trials. As a result of the UCB decision to terminate the two previous Phase III SLE trials, the Company ceased amortizing to revenue the deferred revenue recorded with the receipt of the up front payments from UCB at the
inception of the license agreement until such time as the obligation period could be determinable.

On August 4, 2009,
Immunomedics received a letter dated July 30, 2009 from UCB stating that UCB has relieved the Company of its remaining obligation under the UCB Agreement, to supply UCB with additional epratuzumab if requested. As this was the only obligation
remaining for Immunomedics under the terms of the UCB Agreement, the Company recorded the $31.1 million deferred revenue under the UCB Agreement as licensing fee revenue during fiscal 2010. The Company did not recognize any License Fee Revenues
under this agreement for the 2011 or the 2009 fiscal years.

12. Commitments and Contingencies

Dr. Goldenbergs annual bonus target is 50% of his annual base salary, subject to achievement of performance goals, with a potential payout from 0 to 150% of the target amount. As part of this agreement a $150,000 annual minimum payment is
required to be paid in the aggregate against all Revenue Incentive Compensation and Royalty Payments.

On July 1, 2011,
the Company and Cynthia L. Sullivan entered into the Fourth Amended and Restated Employment Agreement pertaining to Ms. Sullivans service as the Companys President and Chief Executive Officer (see Note 15). Ms. Sullivans
annual base salary under this new agreement is $558,600, which shall be reviewed annually for appropriate increases by the Board of Directors or the Compensation Committee. Ms. Sullivan is also eligible to participate in the Companys
incentive compensation plan in place for its senior level executives. Ms. Sullivans annual bonus target is 50% of her base salary, subject to achievement of performance goals, with a potential payout from 0 to 150% of the target amount.

Operating Lease

Immunomedics is obligated under an operating lease for facilities used for research and development, manufacturing and office space. In June 2009, the Company amended the agreement which increased the
leased space at the facility by 11,000 square feet, which became effective April 1, 2011. With this additional space the Company occupies the entire facility. In February 2011, the Company renewed the lease for an additional term of 10 years
expiring in October 2031 at a base annual rate of $0.8 million, which is fixed through October 2016 and increases thereafter every five years. The Company subleases approximately 1,400 square feet to CMMI for their operations. Rental expense related
to this lease was approximately $0.7 million for each of the 2011, 2010 and 2009 fiscal years.

Including the extension of the
facility lease as described above, the minimum lease commitments for facilities are as follows for fiscal years (in thousands):



|           |  |   |        | 
|---------- |  | - | ------ | 
|2012       |  | $ | 771    | 
|2013       |  | $ | 838    |

|2016       |  | $ | 838    | 
|Thereafter |  | $ | 16,076 | 

Legal Matters

Immunomedics is a party to various claims and litigation arising in the normal course of business, which includes some or all of certain of its patents. While it is not possible to determine the outcome
of these matters, the Company believes that the resolution of all such matters will not have a material adverse effect on its consolidated financial position or liquidity, but could possibly be material to its consolidated results of operations in
any one accounting period.

The following is a summary of a particular claim that is outstanding:

Former Investment Advisor/Broker

On April 15, 2009, the Company initiated arbitration before the Financial Industry Regulatory Authority (FINRA) against its former investment advisor/broker (Banc of America Investment
Services, Inc. and Banc of America Securities, LLC). In the arbitration, the Company claims that the respondents violated the New Jersey Uniform Securities Law, the North Carolina Securities Act, and certain FINRA rules by, among other things,
making false representations and/or material omissions concerning ARS, inappropriately advising investment in ARS, and failing to supervise their employees. The Company continues to seek relief pursuant to the New Jersey Uniform Securities Law and
the North Carolina Securities Act for the difference between the par value of its ARS and the amount the Company received when it sold the ARS on the secondary market, ($2.9 million). The Company has also requested compensatory damages,
consequential damages, punitive damages, and other relief. The arbitration hearing began in September 2010 and is scheduled to resume in September 2011.

13. Geographic Segments

Immunomedics manages its operations as one line of
business of researching, developing, manufacturing and marketing biopharmaceutical products, particularly antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases, and it currently reports as a single
industry segment. Immunomedics markets and sells its products in the United States and throughout Europe.

|Item 9. | Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

|Item 9A. | Controls and Procedures
|-------- | -----------------------

Disclosure Controls and Procedures:We maintain controls and procedures designed to ensure that we are able to collect the information we are required to disclose in the reports we file with the
SEC, and to record, process, summarize and disclose this information within the time periods specified in the rules promulgated by the SEC. Our Chief Executive and Chief Financial Officers are responsible for establishing and maintaining these
disclosure controls and procedures and as required by the rules of the SEC, to evaluate their effectiveness. Based on their evaluation of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K,
our Chief Executive and Chief Financial Officers believe that these procedures are functioning effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934
is (i) recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and (ii) accumulated and communicated to our management, including our chief executive officer and chief financial
officer, as appropriate to allow timely decisions regarding disclosures.

Managements Report on Internal Control Over
Financial Reporting:Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control
over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our
internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of
Immunomedics; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are
being made only in accordance with authorizations of our management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have
a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial
reporting as of June 30, 2011. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on its assessment
and those criteria, our management has concluded we maintained effective internal control over financial reporting as of June 30, 2011.

Our independent registered public accounting firm has issued an attestation report on the effectiveness of Immunomedics internal control over financial reporting.

Changes in internal controls: Such evaluation did not identify any changes in our internal controls over financial reporting that
occurred during the three month period ended June 30, 2011 that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of

Immunomedics, Inc.

We have
audited Immunomedics Inc.s internal control over financial reporting as of June 30, 2011, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (the COSO criteria). Immunomedics Inc.s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included
in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys
internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions
and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that
receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Immunomedics Inc. maintained, in all material respects, effective internal control over financial reporting as of
June 30, 2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated balance sheets of Immunomedics, Inc. and subsidiaries as of June 30, 2011 and 2010 and the related consolidated statements of operations and comprehensive income (loss),
shareholders equity (deficit) and cash flows for each of the three years in the period ended June 30, 2011 of Immunomedics, Inc. and our report dated August 24, 2011 expressed an unqualified opinion.
