PART I

 

Item 1. BUSINESS.

The following discussion of our business contains forward-looking statements that involve risks and uncertainties. When used in this report, the words “intend,” “anticipate,” “believe,” “estimate,” “plan” and “expect” and similar expressions as they relate to us are included to identify forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements and are a result of certain factors, including those set forth under “Certain Factors that May Affect Future Results” and elsewhere in this Annual Report on Form 10-K.

We are developing novel therapeutics for the treatment of diseases of the central nervous system. We also own intellectual property on two biological therapies which may provide future revenues to support our product development efforts in neurological diseases. We also are a leading manufacturer of Protein A which is used in the production of many therapeutic monoclonal antibodies.

Our business strategy is to maintain full commercial rights to our product candidates through “proof of principle” clinical studies after which we may seek corporate partners for further development and marketing. We partially fund the development of our proprietary therapeutic product candidates with the profits derived from the sales of our commercial products. This will enable us to independently advance our product candidates while at the same time minimize our operating losses.

We were incorporated in May 1981, under the laws of the State of Delaware. Our principle executive offices are at 41 Seyon Street, Waltham, Massachusetts 02453 and our telephone number is (781) 250-0111.

Currently Marketed Products

We currently sell two products: Protein A, which is used in the production of monoclonal antibodies, and SecreFlo®, a synthetic form of the hormone secretin, which is used as an aid in the diagnosis of certain diseases of the pancreas.

Protein A Products for Antibody Manufacturing

Protein A is widely used in the purification of therapeutic monoclonal antibodies. Most therapeutic monoclonal antibodies are manufactured by the fermentation of mammalian cells that express the monoclonal antibody. The monoclonal antibody is typically produced by a process in which an impure fermentation broth containing the desired monoclonal antibody is passed over a solid support to which Protein A has been chemically attached or “immobilized”. The immobilized Protein A binds the monoclonal antibody while other impurities are washed away. The monoclonal antibody is then recovered from the support in a substantially purified form.

We manufacture and market several products based on recombinant forms of Protein A. Our primary customers incorporate our Protein A products into their proprietary monoclonal antibody purification systems that they sell directly to the biotechnology and pharmaceutical industry. In February 2005 we announced an amended and expanded Supply Agreement (“the Agreement”) with GE Healthcare (“GEHC”), the leading supplier of purification products to the biopharmaceutical industry and the largest consumer of Protein A. The Agreement calls for Repligen to be the primary supplier of Protein A to GEHC through 2010. We are also collaborating with GEHC to scale-up the production of a modified form of Protein A which may provide additional value to the producers of monoclonal antibodies. The majority of our product sales for the last three years have been sales of Protein A products.

Sales of therapeutic monoclonal antibodies have increased from $300 million in 1997 to approximately $15 billion in 2005. This growth is based on the increasing use of therapeutic antibodies, including Erbitux® for colon

Table of Contents

cancer, Synagis® for RSV infection and Remicade® for Crohn’s disease and arthritis. There are more than 150 additional monoclonal antibodies in various stages of clinical testing which may lead to additional growth of the antibody market and in turn, increased demand for Protein A.

SecreFlo® for Pancreatic Diagnosis

In October 1999, we licensed exclusive commercial rights to a diagnostic product based on a synthetic form of porcine (pig-derived) secretin, which we market as SecreFlo®, from ChiRhoClin, Inc. (“ChiRhoClin”), a private company. ChiRhoClin is our sole supplier of SecreFlo®. SecreFlo® is approved by the U.S. Food and Drug Administration (“FDA”) as an aid in the diagnosis of chronic pancreatitis and gastrinoma (a form of cancer) and as an aid during endoscopic retrograde cholangiopancreatography (“ERCP”), a gastrointestinal procedure. In 2004 we terminated our agreement with ChiRhoClin for breach and filed an arbitration proceeding against ChiRhoClin for their alleged failure to meet certain obligations related to product and clinical development. In May 2005 we announced the settlement of the arbitration proceeding through an agreement by which we will continue to sell SecreFlo® for the next few years.

Intellectual Property on Monoclonal Antibody and Antibody Fusion Products

Erbitux®

Erbitux® is a monoclonal antibody developed by ImClone Systems (“Imclone”) which was approved by the FDA in February 2004 for the treatment of certain forms of colon cancer and in March 2006 for the treatment of head and neck cancer. We believe that Erbitux® is manufactured with a cell line created by a company whose assets were subsequently acquired by Repligen. This cell line contains certain patented genetic technologies (“DNA enhancers”) which increase the productivity of a cell line. This patent is assigned to MIT and exclusively licensed to Repligen. Imclone previously announced that it had manufactured approximately $1 billion of Erbitux® as of February 2004. Imclone recently reported that nearly all of this pre-approval stockpile of Erbitux® was exhausted by the end of December 2005. In May 2004, Repligen and MIT filed a lawsuit against Imclone alleging that Imclone has infringed our patent rights in its production of Erbitux®. Our patent expired in May 2004 and we have applied for a 5 year term extension for the patent, or until May 2009.

CTLA4-Ig

CTLA4 is a key regulator of the activity of the immune system. CTLA4 “turns off” the immune system after it has successfully cleared a bacterial or viral infection by blocking the activation of T-cells, the immune cells responsible for initiating an immune response. In the 1990’s our collaborators at the University of Michigan and the U.S. Navy demonstrated in animal models that a fusion protein consisting of fragments of CTLA4 and an antibody (“CTLA4-Ig”) could be used to block organ transplant rejection and to treat certain autoimmune diseases. Additional animal and human studies by many other groups have confirmed that CTLA4-Ig may be useful in treating diseases such as rheumatoid arthritis, multiple sclerosis, lupus, psoriasis and organ transplant rejection. CTLA4-Ig’s mechanism of action is different from the current therapies for autoimmune disease or organ transplant rejection, thus it may provide a treatment for patients who are refractory to existing therapies.

In February 2004, we were issued a U.S. patent covering the use of CTLA4-Ig for the treatment of rheumatoid arthritis, multiple sclerosis and lupus. This patent is in force until 2021. In August 2004 we were issued a European patent covering the use of CTLA4-Ig for the treatment of autoimmune disease including rheumatoid arthritis as well as organ transplant rejection. This patent is in force until 2013.

In December 2005, the FDA approved Bristol-Myers Squibb Corporation’s (“Bristol”) application to market CTLA4-Ig, under the brand name Orencia®, for treatment of rheumatoid arthritis. Bristol started commercial sales of Orencia® in February 2006.

In January 2006, Repligen and The University of Michigan jointly filed a complaint against Bristol in the United States District Court for the Eastern District of Texas for infringement of U.S. Patent No. 6,685,941. The

patent, entitled “Methods of Treating Autoimmune Disease via CTLA4-Ig,” covers methods of using CTLA4-Ig to treat rheumatoid arthritis, as well as other therapeutic methods. Repligen has exclusive rights to this patent from its owners, the University of Michigan and the U.S. Navy.

Development Stage Products for Neuropsychiatric Disorders

Secretin

Secretin is a well-known hormone produced in the small intestine that regulates the function of the pancreas as part of the process of digestion. More recently, secretin and its receptor have been found in the central nervous system, suggesting a possible role as a neurotransmitter. We are evaluating secretin as a treatment for schizophrenia and for improvement of MRI imaging of the pancreas.

Schizophrenia is a serious, disabling and chronic mental disorder that affects 2 million people in the United States. Schizophrenia is characterized by thought disorders such as delusions or hallucinations, as well as social withdrawal, lack of initiative, and cognitive deficits. Current antipsychotic drugs are effective in reducing thought disorders in some patients but have limited effects on the social withdrawal or cognitive symptoms. The total cost for the care and treatment of patients with schizophrenia in the United States in 2002 was over $60 billion.

We have completed enrollment in a follow-on study to assess the impact of RG1068, synthetic human secretin, on a surrogate marker for a cognitive deficit characteristic of patients with schizophrenia. This study was conducted to determine if the preliminary finding that secretin may have had an impact on a cognitive deficit in schizophrenia is reproducible and related to drug treatment. This was an investigator initiated study conducted by Indiana University Hospital School of Medicine. Twenty-eight patients were assigned to one of two double blind treatment groups, and received either subcutaneous saline or subcutaneous RG1068. Additional assessments were made on the patients to investigate the effects of RG1068 on information processing and affect modulation. A preliminary review of the blinded data suggests that while there may be an effect of drug treatment, further analysis of the data will be necessary to understand the potential impact of secretin on this patient population.

Secretin has gained acceptance especially in Europe for use with abdominal MRI imaging to improve visualization of pancreaticobiliary structures and to increase diagnostic sensitivity relative to unenhanced abdominal MRI. MRI technology images stationary water thus the use of secretin during MRI harnesses the natural biologic properties of secretin, which signals the release of water-rich fluids into the ducts of the pancreas. Improvement in the detection and delineation of normal and abnormal structures with MRI is attractive for patient care as it can obviate the need for more risky invasive procedures.

In June, we initiated a clinical trial to evaluate the use of RG1068 as an agent to improve the detection of structural abnormalities of the pancreatic ducts during MRI imaging of the pancreas. This is a multi-center, baseline controlled, single dose study in which 80 patients with a history of pancreatitis will receive a secretin-enhanced MRI and an unenhanced MRI of the pancreas. This study will assess the sensitivity and specificity of secretin-enhanced MRI to improve the ability to detect pancreatic duct abnormalities relative to unenhanced MRI as well as the safety of secretin in combination with MRI. This study is being initiated at approximately 8-10 clinical sites. Discussions with the FDA have resulted in a consensus on the design of a clinical study to support this indication including patient selection, study operations and endpoints.

Uridine

Uridine is a biological compound essential for the synthesis of DNA and RNA, the basic hereditary material found in all cells, and numerous other factors essential for cell metabolism. Uridine is synthesized by the power plant of the human cell known as the mitochondria. The rationale for uridine therapy in CNS disorders is supported by pre-clinical and clinical research. Researchers at McLean Hospital previously demonstrated that

Table of Contents

uridine is active in a well-validated animal model of depression. Recent reports indicate that certain genes that encode for mitochondrial proteins are significantly down-regulated in the brains of bipolar patients. This new insight suggests that the symptoms of bipolar disorder may be linked to dysregulation of energy metabolism of the brain.

Bipolar disorder, also known as manic depression, is marked by extreme changes in mood, energy and behavior in which a person can alternate between mania (highs) and depression (lows). Bipolar disorder affects more than 2 million adults in the United States. Current drug therapy for bipolar disorder includes the use of lithium and anti-depressants. However side effects are frequent and troublesome, and patients do not respond fully, leading to frequent recurrences of mania and depression.

In March 2006 we initiated a Phase 2 clinical trial of RG2417, an oral formulation of uridine, in patients with bipolar depression. This Phase 2 study is a multi-center, dose escalating study in which 80 patients will receive either RG2417 or a placebo for 6 weeks. Patients will be evaluated for the safety and effectiveness of RG2417 on the symptoms of bipolar depression. This study is being conducted under a development agreement with the Stanley Medical Research Institute, under which Repligen will receive approximately $1,200,000 in funding. The Stanley Medical Research Institute is the largest nonprofit provider of funding for research on schizophrenia and bipolar disorder in the United States.

Repligen previously completed a 6-week Phase 1 clinical trial of a prodrug of uridine (RG2133) in patients with bipolar disorder or major depression. The results demonstrated that administration of RG2133 in this patient population appeared to be safe, did not induce mania, and provided early evidence of a clinical effect of the drug. The trial evaluated 19 patients and was carried out by investigators at McLean Hospital, the largest psychiatric clinical care, teaching and research affiliate of Harvard Medical School.

Repligen’s Business Strategy

Our business strategy is to maintain full commercial rights to our product candidates through “proof of principle” clinical studies after which we may seek corporate partners for further development and marketing. We partially fund the development of our proprietary therapeutic product candidates with the profits derived from the sales of our commercial products. This will enable us to independently advance our product candidates while at the same time minimize our operating losses.

Sales and Marketing

We sell our Protein A products primarily through value-added resellers including GEHC and Applied Biosystems, Inc., as well as through distributors in certain foreign markets. We market SecreFlo® directly to gastroenterologists in the United States.

Significant Customers and Geographic Reporting

Customers for our Protein A products include chromatography companies, diagnostics companies, biopharmaceutical companies and laboratory researchers. During fiscal year 2006, the customers that accounted for more than 10% of our total revenue were GEHC and Applied Biosystems, Inc. During fiscal year 2005, the customers that accounted for more than 10% of our total revenue were GEHC, Applied Biosystems, Inc. and Cardinal Healthcare. During fiscal 2004, the customers that accounted for more than 10% of our total revenue were GEHC and Cardinal Healthcare.

Of our fiscal 2006 revenue, 48% is attributable to U.S. customers and 52% is attributable to foreign customers, of which 75% is attributable to two customers. Of our fiscal 2005 revenue, 43% is attributable to U.S. customers and 56% is attributable to foreign customers, of which 77% is attributable to three customers. Of our fiscal 2004 revenue, 50% is attributable to U.S. customers and 50% is attributable to foreign customers, of which 54% is attributable to two customers.

Employees

As of June 6, 2006 we had 43 employees. Of those employees, 30 were engaged in research, development and manufacturing and 13 in administrative and marketing functions. Fifteen of our employees hold doctorates or other advanced degrees. Each of our employees has signed a confidentiality agreement. None of our employees are covered by collective bargaining agreements.

Patents, Licenses and Proprietary Rights

Our policy is to seek patent protection for our therapeutic product candidates. We pursue patent protection in the United States and file corresponding patent applications in relevant foreign jurisdictions. We believe that patents are an important element in the protection of our competitive and proprietary position, but other elements, including trade secrets, orphan drug status and know-how, may also be important. We own or have exclusive rights to more than 15 issued U.S. patents and corresponding foreign equivalents. The terms of such patents expire at various times between 2009 and 2021. No patent material to our business expires before 2009. In addition, we have rights to more than 20 U.S. pending patent applications and corresponding foreign applications. The invalidation of key patents owned or licensed by us or the failure of patents to issue on pending patent applications could create increased competition, with potential adverse effects on our business prospects. For each of our license agreements where we license the rights to patents or patent applications, the license will terminate on the day that the last to expire patent covered by each such license agreement expires.

We also rely upon trade secret protection for our confidential and proprietary information. Our policy is to require each of our employees, consultants, business partners and significant scientific collaborators to execute confidentiality agreements upon the commencement of an employment, consulting or business relationship with us. These agreements generally 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 employees and consultants, the agreements generally provide that all inventions conceived by the individual in the course of rendering services to Repligen shall be our exclusive property.

Secretin

We are currently prosecuting patent applications for the use of secretin for the treatment of anxiety disorders and schizophrenia in the United States and key foreign markets. In March 2003, the University of North Carolina (“UNC”) filed patent applications claiming the use of secretin for the treatment of certain behavioral disorders, including schizophrenia. In March 2004, we exclusively licensed UNC’s rights in this area, which is unrelated to SecreFlo®.

CTLA4-Ig

We are the exclusive licensee of all CTLA4-Ig patent rights owned by the University of Michigan (“Michigan”). In February 2004, U.S. Patent No. 6,685,941 (“the ‘941 patent”) issued, to which we own the exclusive rights through license agreements with Michigan and the U.S. Navy. The ‘941 patent has claims that cover the use of CTLA4-Ig to treat rheumatoid arthritis, multiple sclerosis and certain other autoimmune disorders and is assigned to the University of Michigan and the U.S. Navy. The ‘941 patent expires in 2021. In August 2004, we were granted a European patent which claims the use of CTLA4-Ig in the treatment of autoimmune disease including rheumatoid arthritis as well as organ transplant. This patent will remain in force until 2013. Under the European system third parties can file oppositions to patents during the nine months following grant of a European patent. On May 4, 2005, Bristol filed an opposition to our European patent which initiates the opposition process and we have answered Bristol’s opposition papers. The European Patent Office (EPO) will next schedule a hearing to allow both sides to orally present their case, following which a ruling will be made. The ruling will either uphold the patent claims as granted, modify the claims, or rescind the claims.

Table of Contents

Any ruling may be appealed, in whole or in part. Regardless of an opposition or any outcome during the opposition process, a granted European patent is held to be in effect and valid for its natural term or until such time as all final appeals are exhausted or waived. We intend to vigorously defend our granted European patent through the opposition process.

Uridine

In November 2000 and December 2000, Repligen entered into two license agreements (the “UCSD Uridine License Agreements”) with the University of California, San Diego (“UCSD”) for certain patent applications pertaining to the use of uridine and uridine derivatives for the treatment of mitochondrial disease and purine autism. On June 21, 2001, Pro-Neuron, Inc. filed a complaint (the “Pro-Neuron Complaint”) against the Regents of the University of California (the “Regents”) and Repligen in the Superior Court of California, County of San Diego seeking to void the UCSD Uridine License Agreement relating to treatment of mitochondrial disease entered into between Repligen and the UCSD. Pro-Neuron, Inc. subsequently amended the complaint to include the UCSD Uridine License Agreement related to purine autism and claims for misappropriation of trade secrets.

In June 2003, Repligen agreed to restructure the UCSD License Agreements to exclude the field of acylated pyrimidines, including triacetyluridine.

In April 2004, a U.S. patent was issued to Repligen and University of California, which claims methods of treating certain developmental disorders, including certain forms of autism, with uridine compositions which expires in October 2020. Foreign equivalents of this patent are pending. A patent with similar claims has recently issued in Australia.

Protein A

We own a U.S. patent covering recombinant Protein A, which expires in 2009, as well as significant know-how in the manufacture of high-purity Protein A. We also own a U.S. patent covering modified forms of Protein A, which was non-exclusively licensed to Amersham Biosciences (now GEHC) in 1998 as part of a ten year agreement, which was amended and extended in 2005 until 2010, covering the supply of Protein A to GEHC.

In addition to its utility in monoclonal antibody manufacturing, Protein A may also be useful in human therapy based on its activity as a B-cell toxin. Repligen has exclusively licensed rights from the University of California, San Diego to a United States patent application which claims a variety of potential therapeutic uses of Protein A. Foreign equivalents of this patent application are also pending.

Research and Development

For the past three years, we have devoted substantially all of our resources to the research and development of therapeutic product candidates and our commerical products and product candidates discussed herein. We spent $5,163,000 in fiscal 2006, $5,037,000 in fiscal 2005, and $6,484,000 in fiscal 2004 on company-sponsored research and development activities.

Competition

Our Protein A and SecreFlo® products compete on the basis of quality, performance, cost effectiveness, and application suitability with numerous established technologies. Additional products using new technologies that may be competitive with our products may also be introduced. Many of the companies selling or developing competitive products have financial, manufacturing and distribution resources significantly greater than ours.

The field of drug development is characterized by rapid technological change. New developments are expected to continue at a rapid pace in both industry and academia. There are many companies, both public and

 

7


Table of Contents

private, including large pharmaceutical companies, chemical companies and specialized biotechnology companies, engaged in developing products competitive with products that we have under development. Many of these companies have greater capital, human resources, research and development, manufacturing and marketing experience than we do. They may succeed in developing products that are more effective or less costly than any that we may develop. These competitors may also prove to be more successful than we are in production and marketing. In addition, academic, government and industry-based research groups compete intensely with us in recruiting qualified research personnel, in submitting patent filings for protection of intellectual property rights and in establishing corporate strategic alliances. We cannot be certain that research, discoveries and commercial developments by others will not render any of our programs or potential products noncompetitive.

Manufacturing

Protein A for Antibody Manufacturing

We manufacture Protein A products from recombinant strains of bacteria. We manufacture Protein A for GEHC under a ten-year supply agreement which was initiated in December 1998. In February 2005, we announced an amended and expanded Supply Agreement with GEHC, the leading supplier of purification products to the biopharmaceutical industry and the largest consumer of Protein A. While third parties carry out certain fermentation and certain recovery operations, the purification, immobilization, packaging and quality control testing of Protein A are conducted at our facilities. We maintain an active quality assurance effort to support the regulatory requirements of our customers. We purchase raw materials from more than one commercially established company and believe that the necessary raw materials are currently commercially available in sufficient quantities necessary to meet market demand.

SecreFlo® (synthetic porcine secretin)

SecreFlo® our diagnostic secretin product, is purchased from ChiRhoClin who contracts with third parties for the synthesis of the drug substance and the drug product. This company is our sole supplier for this product. Under the terms of a settlement agreement, ChiRhoClin is obligated to deliver a certain amount of SecreFlo® to Repligen over the next few years. After depletion of all supplies of SecreFlo®, including those to be delivered under the settlement agreement, Repligen will cease marketing and selling SecreFlo®. (For more information about the settlement agreement with ChiRhoClin, please see “Item 3 Legal Proceedings.”)

Therapeutic Product Candidates

We currently rely, and will continue to rely, for at least the next few years, upon contract manufacturers for both the procurement of raw materials and the production of our product candidates for use in our clinical trials. Our product candidates will need to be manufactured in a facility by processes that comply with the FDA’s good manufacturing practices and other similar regulations. It may take a substantial period of time to begin manufacturing our products in compliance with such regulations. If we are unable to establish and maintain relationships with third parties for manufacturing sufficient quantities of our product candidates and their components that meet our planned time and cost parameters, the development and timing of our clinical trials may be adversely affected.

We purchase raw materials from more than one commercially established company. Our necessary raw materials are currently commercially available in quantities that far exceed the scale required to complete all of our future planned clinical trials.

Government Regulation

The development of drug candidates is subject to regulation in the United States by the FDA and abroad by foreign equivalents. Product development and approval within the FDA regulatory framework usually takes a significant number of years and involves the expenditure of substantial capital resources. Timelines for development are uncertain.

Table of Contents

Before clinical testing in the United States of any drug candidate may begin, FDA requirements for preclinical efficacy and safety must be completed. Required toxicity testing typically involves characterization of the drug candidate in several animal species. Safety and efficacy data are submitted to the FDA as part of an Investigational New Drug Application (“IND”) and are reviewed by the FDA prior to the commencement of human clinical trials.

Clinical trials involve the administration of the drug to human volunteers or patients under the supervision of a qualified investigator, usually a physician, with an FDA-approved protocol. Human clinical trials are typically conducted in three sequential phases:

 

    Phase 1 clinical trials represent the initial administration of the investigational drug to a small group of human subjects to test for safety (adverse effects), dose tolerance, absorption, biodistribution, metabolism, excretion and clinical pharmacology and, if possible, to gain early evidence regarding efficacy.

 

    Phase 2 clinical trials typically involve a small sample of the actual intended patient population and seek to assess the efficacy of the drug for specific targeted indications, to determine dose tolerance and the optimal dose range, and to gather additional information relating to safety and potential adverse effects.

 

    Once an investigational drug is found to have some efficacy and an acceptable safety profile in the targeted patient population, Phase 3 clinical trials are initiated to establish further clinical safety and efficacy of the investigational drug in a broader sample of the general patient population at multiple study sites in order to determine the overall risk-benefit ratio of the drug and to provide an adequate basis for product approval. The Phase 3 clinical development program consists of expanded, large-scale studies of patients with the target disease or disorder to obtain definitive statistical evidence of the efficacy and safety of the proposed product.

All data obtained from a comprehensive development program are submitted in a New Drug Application (“NDA”) to the FDA and the corresponding agencies in other countries for review and approval. The NDA includes information pertaining to clinical studies and the manufacture of the new drug. Review of an NDA by the FDA can be a time-consuming process and the FDA may request that we submit additional data or carry out additional studies.

Item 1A. RISK FACTORS

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

Investors should carefully consider the risk factors described below before making an investment decision.

If any of the events described in the following risk factors occur, our business, financial condition or results of operations could be materially harmed. In that case the trading price of our common stock could decline, and Investors may lose all or part of their investment. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial may also become important factors that affect Repligen.

This annual report on Form 10-K contains forward looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this annual report on Form 10-K.

We are dependent on others to develop, conduct clinical trials for, manufacture, market and sell our principal products.

We conduct some of our development activities, and conduct most of our commercialization activities, through collaborations. These collaborations include academic researchers as well as contracts with vendors. Our collaborations are heavily dependent on the efforts and activities of our collaborative partners. Our existing and any future collaborations may not be technically or commercially successful. For example, if any of our collaborative partners were to breach or terminate an agreement with us, reduce its funding or otherwise fail to conduct the collaboration successfully, we may need to devote additional internal resources to the program that is the subject of the collaboration, scale back or terminate the program or seek an alternative partner, any of which could lead to delays in development and/or commercialization of our products.

If our clinical trials are not successful, we will not be able to develop and commercialize any related products.

In order to obtain regulatory approvals for the commercial sale of our future products, we and our collaborative partners will be required to complete extensive clinical trials in humans to demonstrate the safety and efficacy of the products. We have limited experience in conducting clinical trials.

The submission of an IND may not result in FDA authorization to commence clinical trials. If clinical trials begin, we or our collaborative partners may not complete testing successfully within any specific time period, if at all, with respect to any of our products. Furthermore, we, our collaborative partners, or the FDA, may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to unacceptable health risks. Clinical trials, if completed, may not show any potential product to be safe or effective. Thus, the FDA and other regulatory authorities may not approve any of our potential products for any indication.

The rate of completion of clinical trials is dependent in part upon the rate of enrollment of patients. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the study, and the existence of competitive clinical trials. Delays in planned patient enrollment may result in increased costs and delays in completion of clinical trials.

We may not obtain regulatory approvals; the approval process is costly and lengthy.

We must obtain regulatory approval for our ongoing development activities and before marketing or selling any of our future products. We may not receive regulatory approvals to conduct clinical trials of our products or to manufacture or market our products. In addition, regulatory agencies may not grant such approvals on a timely basis or may revoke previously granted approvals.

The process of obtaining FDA and other required regulatory approvals is lengthy and expensive. The time required for FDA and other clearances or approvals is uncertain and typically takes a number of years, depending on the complexity and novelty of the product. Our analysis of data obtained from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. Any delay in obtaining or failure to obtain required clearance or approvals could materially adversely affect our ability to generate revenues from the affected product. We have only limited experience in filing and prosecuting applications necessary to gain regulatory approvals.

We are also subject to numerous foreign regulatory requirements governing the design and conduct of the clinical trials and the manufacturing and marketing of our future products. The approval procedure varies among countries. The time required to obtain foreign approvals often differs from that required to obtain FDA approvals. Moreover, approval by the FDA does not ensure approval by regulatory authorities in other countries (or vice versa).

All of the foregoing regulatory risks also are applicable to development, manufacturing and marketing undertaken by our collaborative partners or other third parties.

Even if we obtain marketing approval, our products will be subject to ongoing regulatory review which will be expensive and may affect our ability to successfully commercialize our products.

Even if we or our collaborative partners receive regulatory approval of a product, such approval may be subject to limitations on the indicated uses for which the product may be marketed, which may limit the size of the market for the product or contain requirements for costly post-marketing follow-up studies. The manufacturers of our products for which we or our collaborative partners have obtained marketing approval will be subject to continued review and periodic inspections by the FDA and other regulatory authorities. The subsequent discovery of previously unknown problems with the product, clinical trial subjects, or with a manufacturer or facility may result in restrictions on the product or manufacturer, including withdrawal of the product from the market.

If we or our collaborative partners fail to comply with applicable regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

If we are unable to obtain, maintain and enforce patents for our products, we will not be able to succeed commercially.

We must obtain and maintain patent and trade secret protection for those of our products and processes for which patent protection is available in order to protect them from unauthorized use and to produce a financial return consistent with the significant time and expense required to bring our products to market. Our success will depend, in part, on our ability to:

 

    obtain and maintain patent protection for our products and manufacturing processes;

 

    preserve our trade secrets;

 

    operate without infringing the proprietary rights of third parties; and

 

    secure licenses from others on acceptable terms.

We cannot be sure that any patent applications relating to our products that we will file in the future or that any currently pending applications will issue on a timely basis, if ever. Since patent applications in the United States filed prior to November 2000 are maintained in secrecy until patents issue and since publication of discoveries in the scientific or patent literature often lag behind actual discoveries, we cannot be certain that we were the first to make the inventions covered by each of our pending patent applications or that we were the first to file patent applications for such inventions. Even if patents are issued, the degree of protection afforded by such patents will depend upon the:

 

    scope of the patent claims;

 

11


Table of Contents
    validity and enforceability of the claims obtained in such patents; and

 

    our willingness and financial ability to enforce and/or defend them.

The patent position of biotechnology and pharmaceutical firms is often highly uncertain and usually involves complex legal and scientific questions. Moreover, no consistent policy has emerged in the United States and in many other countries regarding the breadth of claims allowed in biotechnology patents. Patents which may be granted to us in certain foreign countries may be subject to opposition proceedings brought by third parties or result in suits by us, which may be costly and result in adverse consequences for us.

In some cases, litigation or other proceedings may be necessary to assert claims of infringement, to enforce patents issued to us or our licensors, to protect trade secrets, know-how or other intellectual property rights we own or to determine the scope and validity of the proprietary rights of third parties. Such litigation could result in substantial cost to us and diversion of our resources. An adverse outcome in any such litigation or proceeding could have a material adverse effect on our business, financial condition and results of operations.

If our competitors prepare and file patent applications in the United States that claim technology also claimed by us, we may be required to participate in interference proceedings declared by the U.S. Patent and Trademark Office to determine priority of invention, which would result in substantial costs to us.

We are currently and may in the future be involved in expensive patent litigation or other intellectual property proceedings which could result in liability for damages or stop our development and commercialization efforts.

There has been substantial litigation and other proceedings regarding the complex patent and other intellectual property rights in the pharmaceutical and biotechnology industries. We are a party to, and in the future may become a party to, patent litigation or other proceedings regarding intellectual property rights.

Other types of situations in which we may become involved in patent litigation or other intellectual property proceedings include:

 

    We may initiate litigation or other proceedings against third parties to seek to invalidate the patents held by such third parties or to obtain a judgment that our products or services do not infringe such third parties’ patents.

 

    We may initiate litigation or other proceedings against third parties to seek to enforce our patents against infringement.

 

    If our competitors file patent applications that claim technology also claimed by us, we may participate in interference or opposition proceedings to determine the priority of invention.

 

    If third parties initiate litigation claiming that our processes or products infringe their patent or other intellectual property rights, we will need to defend against such claims.

The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the cost of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. If a patent litigation or other intellectual property proceeding is resolved unfavorably to us, we or our collaborative partners may be enjoined from manufacturing or selling our products and services without a license from the other party and be held liable for significant damages. We may not be able to obtain any required license on commercially acceptable terms or at all.

Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time, attention and resources.

Table of Contents

For more information about the legal proceeding in which we are involved, please see “Legal Proceedings.”

We may become involved in litigation or other proceedings with collaborative partners, which may be time consuming, costly and could result in delays in our development and commercialization efforts.

We conduct some of our development activities, and conduct most of our commercialization activities, through collaborations with collaborative partners. Therefore, any disputes with such partners that lead to litigation or similar proceedings may result in us incurring legal expenses, as well as facing potential legal liability. Such disputes, litigation or other proceedings are also time consuming and may cause delays in our development and commercialization efforts.

We have limited sales and marketing experience and capabilities.

We have limited sales, marketing and distribution experience and capabilities. We may, in some instances, rely significantly on sales, marketing and distribution arrangements with our collaborative partners and other third parties. In these instances, our future revenues will be materially dependent upon the success of the efforts of these third parties.

If in the future we determine to perform sales, marketing and distribution functions ourselves, we would face a number of additional risks, including:

 

    we may not be able to attract and build a significant marketing staff or sales force;

 

    the cost of establishing a marketing staff or sales force may not be justifiable in light of any product revenues; and

 

    our direct sales and marketing efforts may not be successful.

We have limited manufacturing capabilities and will be dependent on third party manufacturers.

We have limited manufacturing experience and no commercial or pilot scale manufacturing facilities for the production of pharmaceuticals. In order to continue to develop pharmaceutical products, apply for regulatory approvals and, ultimately, commercialize any products, we may need to develop, contract for, or otherwise arrange for the necessary manufacturing capabilities.

We currently rely upon third parties to produce material for preclinical and clinical testing purposes and expect to continue to do so in the future. We also expect to rely upon third parties, including our collaborative partners, to produce materials required for the commercial production of certain of our products if we succeed in obtaining necessary regulatory approvals. We believe that there is no proprietary aspect to the manufacture of our products. However, there are only a limited number of manufacturers that operate under the FDA’s regulations for good manufacturing practices which are capable of and/or approved to manufacture our products. Timing for the initiation of new manufacturers is uncertain, and, if we are unable to arrange for third party manufacturing of our products on a timely basis, or to do so on commercially reasonable terms, we may not be able to complete development of our products or market them. We currently rely upon third parties for fermentation relating to our Protein A products.

We believe that there is no proprietary aspect to the manufacture of our commercial products. However, timing for the initiation of new manufacturers is uncertain, and, if we are unable to arrange for third party manufacturing of our products on a timely basis, or to do so on commercially reasonable terms, we may not be able to complete development of our products or market them. To the extent that we enter into manufacturing arrangements with third parties, we are dependent upon these third parties to perform their obligations in a timely manner. If such third party suppliers fail to perform their obligations, we may be adversely affected in a number of ways, including:

 

    we may not be able to meet commercial demands for our products;

 

13


Table of Contents
    we may not be able to initiate or continue clinical trials of products that are under development;

 

    we may be delayed in completing our clinical trials of products under development; and

 

    we may be delayed in submitting applications for regulatory approvals for our products.

The manufacture of products by us and our collaborative partners and suppliers is subject to regulation by the FDA and comparable agencies in foreign countries. Delay in complying or failure to comply with such manufacturing requirements could materially adversely affect the marketing of our products.

We rely on a single supplier (ChiRhoClin) for our SecreFlo® product

We rely on a single supplier (ChiRhoClin) for our SecreFlo® product. Under the terms of our settlement agreement, ChiRhoClin is obligated to deliver a certain amount of SecreFlo® to Repligen over the next few years. After depletion of all supplies of SecreFlo®, including those to be delivered under the settlement agreement, Repligen will cease marketing and selling SecreFlo®. In the event that we are unable to acquire additional products, our revenues may be negatively impacted. (For more information about the settlement agreement regarding SecreFlo®, please see “Legal Proceedings.”)

If we are unable to continue to hire and retain skilled personnel, then we will have trouble developing and marketing our products.

Our success depends largely upon the continued service of our management and scientific staff and our ability to attract, retain and motivate highly skilled technical, scientific, management, regulatory compliance and marketing personnel. Potential employees with an expertise in the field of molecular biology, biochemistry, regulatory affairs and/or clinical development of new drug and biopharmaceutical manufacturing are not generally available in the market and are difficult to attract and retain. We also face significant competition for such personnel from other companies, research and academic institutions, government and other organizations who have superior funding and resources to be able to attract such personnel. The loss of key personnel or our inability to hire and retain personnel who have technical, scientific or regulatory compliance backgrounds could materially adversely affect our product development efforts and our business.

The market may not be receptive to our products upon their introduction.

The commercial success of our products that are approved for marketing will depend upon their acceptance by the medical community and third party payors as being clinically useful, cost effective and safe. All of the products that we are developing are based upon new technologies or therapeutic approaches. As a result, it is hard to predict market acceptance of our products.

Other factors that we believe will materially affect market acceptance of our products and services include:

 

    the timing of receipt of marketing approvals and the countries in which such approvals are obtained;

 

    the safety, efficacy and ease of administration of our products;

 

    the success of physician education programs;

 

    the availability of government and third party payor reimbursement of our products; and

 

    competition from products which may offer better safety, efficacy or lower cost.

We compete with pharmaceutical and biotechnology companies who are capable of developing new approaches that could make our products and technology obsolete.

The market for therapeutic and commercial products is intensely competitive, rapidly evolving and subject to rapid technological change. Pharmaceutical and biotechnology companies may have substantially greater

 

14


Table of Contents

financial, manufacturing, marketing, and research and development resources than we have. New approaches by these competitors may make our products and technologies obsolete or noncompetitive.

We have incurred substantial losses, we expect to continue to incur operating losses and we will not be successful until we reverse this trend.

We have incurred operating losses in each year since our founding in 1981. We expect to continue to incur operating losses for the foreseeable future.

While we generate revenue from product sales, this revenue is not sufficient to cover the costs of our clinical trials and drug development programs. We plan to continue to invest in key research and development activities. As a result, we will need to generate significant revenues in order to achieve profitability. We cannot be certain whether or when this will occur because of the significant uncertainties that affect our business.

If we do not obtain additional capital for our drug development programs, we will be unable to develop or discover new drugs.

We need additional long-term financing to develop our drug development programs through the clinical trial process as required by the FDA and to develop our commercial products business. We also need additional long-term financing to support future operations and capital expenditures, including capital for additional personnel and facilities. If we spend more money than currently expected for our drug development programs and our commercial products business, we will need to raise additional capital by selling debt or equity securities, by entering into strategic relationships or through other arrangements. We may be unable to raise any additional amounts on reasonable terms or when they are needed due to the volatile nature of the biotechnology marketplace. If we are unable to raise this additional capital, we may have to delay or postpone critical clinical studies or abandon other development programs.

Our stock price could be volatile, which could cause you to lose part or all of your investment.

The market price of our common stock, like that of the common stock of many other development stage biotechnology companies, is highly volatile. In addition, the stock market has experienced extreme price and volume fluctuations. This volatility has significantly affected the market prices of securities of many biotechnology and pharmaceutical companies for reasons frequently unrelated to or disproportionate to the operating performance of the specific companies. These broad market fluctuations may adversely affect the market price of our common stock.

Anti-takeover provisions may deter a third party from acquiring us, limiting our stockholders’ ability to profit from such a transaction.

Our Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock, of which 40,000 have been reserved for issuance in connection with our stockholder rights plan, and to determine the price, rights, preferences and privileges of those shares without any further vote or action by our stockholders. We also adopted a “poison pill” stockholder rights plan that will dilute the stock ownership of acquirers of our common stock upon the occurrence of certain events. This stockholder rights plan could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock.

We are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which prohibits us from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person becomes an interested stockholder, unless the business combination is approved in a prescribed manner. This provision could have the effect of delaying or preventing a change of control of the Company. Section 203 and the stockholder rights plan may have the effect of deterring hostile takeovers or delaying or preventing changes in our management, including transactions in which stockholders might otherwise receive a premium for their shares over then current market prices.

Changes in the securities laws and regulations have increased, and are likely to continue to increase our costs.

The Sarbanes-Oxley Act of 2002, which became law in July 2002, has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of that Act, the SEC and the Nasdaq have promulgated new rules and listing standards covering a variety of subjects. Compliance with these new rules and listing standards have increased our legal costs and financial and accounting costs, and we expect these increased costs to continue. Likewise, these developments may make it more difficult for us to attract and retain qualified members of our board of directors, particularly independent directors.

 

Item 1B. NONE

 

Item 2. PROPERTIES.

We lease approximately 25,000 square feet of space in Waltham, Massachusetts, of which approximately 10,000 square feet is manufacturing and laboratory space. The remaining space is used as office space. Our lease expires in January 2013, with options to extend for two five-year periods. During fiscal 2006, we incurred aggregate rental costs for our facility, excluding maintenance, taxes and utilities, of approximately $394,000. Our space is adequate for our current use and for the foreseeable future.

 

Item 3. LEGAL PROCEEDINGS.

Bristol-Myers Squibb Company

In January 2006, Repligen Corporation and The University of Michigan jointly filed a complaint against Bristol in the United States District Court for the Eastern District of Texas for infringement of U.S. Patent No. 6,685,941 (“the ‘941 patent”) for the commercial sale of Orencia®. The ‘941 patent, entitled “Methods of Treating Autoimmune Disease via CTLA4-Ig,” covers methods of using CTLA4-Ig to treat rheumatoid arthritis, as well as other therapeutic methods. Repligen has exclusive rights to this patent from its owners, the University of Michigan and the U.S. Navy. In February, Bristol answered the complaint and counterclaimed seeking a declaratory judgment that the ‘941 patent is invalid and unenforceable and that Bristol does not infringe the patent.

ImClone Systems, Inc.

In May 2004, Repligen Corporation and The Massachusetts Institute of Technology (“MIT”) filed an action for patent infringement in the United States District Court for the District of Massachusetts against ImClone Systems, Inc. (“Imclone”) for infringement of U.S. Patent No. 4,663,281 (“the ‘281 patent”) based on Imclone’s manufacture and sale of the cancer drug Erbitux®. The technology claimed by the ‘281 patent, which was invented by researchers at MIT, covers certain genetic elements (DNA enhancers) that increase protein production in a mammalian cell. Repligen is the exclusive licensee of the ‘281 patent from MIT. Damon Biotech, a predecessor of Repligen, developed the cell line which is used to manufacture Erbitux® in 1990 for the National Cancer Institute and incorporated the DNA enhancer technology which is the basis of the ‘281 patent. Repligen seeks relief, including compensation in the form of royalties for the material Imclone manufactured prior to the expiration of the ‘281 patent in May of 2004.

In February 2006, the Court heard oral arguments on summary judgment motions brought by plaintiffs Repligen and MIT and defendant Imclone on the issue of exhaustion of patent rights. The Court may: 1) rule in plaintiffs’ favor, dispose of Imclone’s patent exhaustion defense and set the case for trial; 2) deny both parties’ motions and set the case for trial; or 3) rule in Imclone’s favor and enter judgment against plaintiffs in the case, subject to appeal.

Table of Contents

Repligen and MIT have also filed an application for patent term extension for the ‘281 patent, which if granted will extend the term of the patent to May 2009.

ChiRhoClin, Inc.

In February 2004, Repligen terminated the September 1999 Licensing Agreement with ChiRhoClin, its supplier of SecreFlo®, based on ChiRhoClin’s alleged failure to meet its obligations under the Licensing Agreement.

On April 9, 2004, Repligen filed an arbitration demand against ChiRhoClin with the American Arbitration Association in New York seeking to recover payments made to ChiRhoClin and additional damages. In this arbitration demand, Repligen alleged that ChiRhoClin breached several of its obligations under the September 1999 Licensing Agreement including failure to use best efforts to obtain various FDA approvals and to manufacture and supply SecreFlo®, in a timely manner. In June 2004, ChiRhoClin filed a counterclaim alleging that Repligen had wrongfully terminated the Licensing Agreement.

On May 9, 2005, Repligen entered into a Settlement Agreement (the “Agreement”) with ChiRhoClin, Inc., in full settlement of the arbitration proceedings described above. Under the terms of the Agreement, Repligen received a payment of $750,000 and will be entitled to continue to market SecreFlo®, for the next several years under a royalty structure more favorable to Repligen than under the Licensing Agreement. ChiRhoClin is obligated to deliver a certain amount of SecreFlo®, to Repligen over the next few years. This payment of $750,000 was recorded as “Accrued Liabilities” as of June 30, 2005. The adoption of EITF 02-16 Accounting by a Customer (Including a Reseller) for Certain Consideration Received from a Vendor has resulted in the reduction of cost of goods sold as future inventory purchased from ChiRhoClin is sold. After depletion of all supplies of SecreFlo® provided by ChiRhoClin, including those to be delivered under the Agreement, Repligen will cease marketing and selling a secretin product supplied by ChiRhoClin. ChiRhoClin will pay Repligen a per unit royalty on all sales by ChiRhoClin of its secretin products subject to certain time and/or volume limits. Repligen is not required to pay approximately $1,170,000 of unremitted royalties to ChiRhoClin related to sales from February 2004 to March 2005. This amount which was accrued at March 31, 2005 was recorded as other income in the quarter ended June 30, 2005. Repligen has received security for ChiRhoClin’s performance under the Agreement.

Other

From time to time, the Company may be subject to other legal proceedings and claims in the ordinary course of business. Repligen is not currently aware of any such proceedings or claims that it believes will have, individually or in the aggregate, a material adverse effect on the business, financial condition or results of operations.

 

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matters were submitted to a vote of the security holders of the Company through the solicitation of proxies or otherwise, during the last quarter of the fiscal year ended March 31, 2006.

Recent Sales of Unregistered Securities

On March 1, 2006, we engaged CEOcast, Inc. to render investor relations services. In exchange and as consideration for CEOcast Inc.’s investor relations services, we issued 25,000 restricted shares of common stock to CEOcast Inc. We recorded the value of these shares as determined using Black-Scholes option pricing model as selling, general and administrative expense in fiscal year 2006 in the accompanying statements of operations. No underwriters were involved in the issuance of this restricted common stock. The shares were issued pursuant to Section 4(2) of the Securities Act of 1933, as amended since the shares were issued to a single entity and based on other facts. The restrictions on the shares will lapse on March 1, 2007.

Overview

We are a biopharmaceutical company focused on the development of novel therapeutics for diseases that affect the central nervous system. A number of drug development programs are currently being conducted to evaluate our naturally occurring drug candidates in diseases such as schizophrenia, bipolar disorder and neurodegeneration. In addition, we sell two commercial products, Protein A for monoclonal antibody purification and SecreFlo® for assessment of pancreatic disorders. In fiscal 2006, we experienced significant growth in sales and profits from our commercial products business. Our business strategy is to deploy the profits from our current commercial products and any revenue that we may receive from our patents to enable us to invest in the development of our product candidates in the treatment area of neuropsychiatric diseases while at the same time minimize our operating losses.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

While our significant accounting polices are more fully described in notes to our financial statements, we have identified the policies and estimates below as critical to our business operations and the understanding of our results of operations. The impact and any associated risks related to these policies on our business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition” and “Results of Operations” where such policies affect our reported and expected financial results.

Revenue Recognition

We apply Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) to our revenue arrangements. We generate product revenues from the sale of our Protein A products to customers in the pharmaceutical and process chromatography industries and from the sale of SecreFlo® to hospital-based gastroenterologists. In accordance with SAB No. 104, we recognize revenue related to product sales upon delivery of the product to the customer as long as there is persuasive evidence of an arrangement, the sales price is fixed or determinable and collection of the related receivable is reasonably assured.

During the fiscal year 2006 ended March 31, 2006, we received $310,000 of cash from a sponsored research and development project under an agreement with the Stanley Medical Research Institute. Research revenue is recognized for costs plus fixed-fee contracts as costs are incurred. During fiscal 2004 we generated non-product revenues from sponsored research and development projects under a Small Business Innovation Research (“SBIR”)

Phase I grant. Research expenses in the accompanying statements of operations include funded and unfunded expenses. Additionally, during fiscal year 2006, the Company earned and recognized approximately $72,000 in royalty revenue from ChiRhoClin, Inc.

Impairment Analysis of Long-lived Assets

We review our long-term assets for impairment at each reporting period in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”.

During fiscal 2003, under the terms of our September 1999 Licensing Agreement with ChiRhoClin, Inc. we made a milestone payment to ChiRhoClin that consisted of $1,250,000 in cash and 696,223 shares of our common stock. We recorded the fair value of the shares issued, $2,576,025, and the cash paid of $1,250,000, as a long-term intangible asset. Beginning in April 2002, we began to amortize this intangible asset to cost of revenue over the remaining term of the license, approximately seven years. We amortized $510,130 during the year ended March 31, 2004.

At March 31, 2004, as a result of a dispute with ChiRhoClin, we recorded an impairment charge of $2,413,244 in our results of operations for the year ended March 31, 2004. During the year ended March 31, 2005, we amortized the remaining balance of this long-term intangible asset of $392,520 to cost of goods sold. This long-term intangible asset was fully amortized at March 31, 2005.

Inventory

We value inventory at cost or, if lower, fair market value. We determine cost using the first-in, first-out method. We regularly review our inventories and record a provision for excess and obsolete inventory based on certain factors that may impact the realizable value of our inventory. Factors we consider include expected sales volume, production capacity and expiration dates. We write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected requirements to cost of goods sold.

Accrued Liabilities

We prepare our financial statements in accordance with accounting principles generally accepted in the United States. These principles require that we estimate accrued liabilities. This process involves identifying services, which have been performed on our behalf, and estimating the level of service performed and the associated cost incurred for such service as of each balance sheet date. Examples of estimated expenses for which we accrue expenses include fees paid to our contract manufacturers in conjunction with the production of clinical materials and service fees paid to organizations for their performance in conducting our clinical trials. In the event that we do not identify certain costs which have begun to be incurred or we under or over-estimate the level of services performed or the costs of such services, our reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services are often judgmental. We make these judgments based upon the facts and circumstances known to us in accordance with generally accepted accounting principles. Repligen was not required to pay approximately $1,170,000 of accrued but unremitted royalties to ChiRhoClin related to sales of Secreflo® from February 2004 to March 2005. This amount was recorded as other income in the quarter ended June 30, 2005.

RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations should be read in conjunction with the accompanying financial statements and the related footnotes thereto.

Revenues

Total revenue for fiscal 2006, 2005 and 2004 were $12,911,000, $9,360,000 and $6,914,000. Revenues for the years ending March 31, 2006, 2005 and 2004 were primarily comprised of sales of our commercial products, Protein A and SecreFlo®. During the fiscal year ended March 31, 2006, 2005 and 2004 sales of our commercial products were:

 

     Year ended March 31    % Change  
     2006    2005    2004    2006 vs. 2005     2005 vs. 2004  
     (in thousands, except percentages)             

Protein A

   $ 10,540    $ 7,134    $ 4,976    48 %   43 %

SecreFlo®

     1,989      2,189      1,867    -9 %   17 %

Other product revenue

Product revenue

   $ 12,529    $ 9,360    $ 6,843    34 %   37 %

Substantially all of our products based on recombinant Protein A are sold to customers who incorporate our manufactured products into their proprietary antibody purification systems to be sold directly to the pharmaceutical industry. Monoclonal antibodies are a well-established class of drug with applications in rheumatoid arthritis, asthma, Crohn’s disease and a variety of cancers. Sales of Protein A are therefore impacted by the timing of large-scale production orders and on the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations.

During fiscal 2006, Protein A sales increased by $3,406,000 as a result of a rise in the demand for our Protein A products. During the fourth quarter of fiscal 2005, a supply agreement with GEHC was amended to expand the scope of manufacturing and extend the term of the agreement through 2010. During fiscal 2004, manufacturing problems experienced by one of our significant customers negatively impacted our sales of Protein A. We anticipate that sales of Protein A will continue to grow during the next year, but at a reduced rate and will continue to be subject to quarterly fluctuations due to timing of large-scale production orders.

Sales of SecreFlo® decreased $200,000 in fiscal 2006 due to competition with our sole supplier of SecreFlo® and as a result of a reduction in sales and marketing efforts. Sales increased $322,000 in fiscal 2005 from $1,867,000 in fiscal 2004 during which a delay in the delivery of a new lot of SecreFlo® from the manufacturer negatively impacted sales. The settlement in fiscal 2005 with our sole supplier of SecreFlo® provides for continued supply during fiscal 2007.

During the fiscal year 2006, we received $310,000 of cash from a sponsored research and development project under an agreement with the Stanley Medical Research Institute. Research revenue is recognized for costs plus fixed-fee contracts as costs are incurred. Additionally, during fiscal year 2006, we earned and recognized approximately $72,000 in royalty revenue from ChiRhoClin, Inc. During fiscal 2004, we generated $71,000 of non-product revenues from sponsored research and development projects under a Small Business Innovation Research (“SBIR”) Phase I grant.

Costs and Operating expenses

Total costs and operating expenses for fiscal 2006, 2005 and 2004 were approximately $14,131,000, $13,522,000 and $16,855,000, respectively.

 

      2006    2005    2004    2006 vs. 2005     2005 vs. 2004  

Costs and operating expenses:

   $ 3,551    $ 3,888    $ 3,248    -9 %   20 %

Research and development

     5,163      5,037      6,484    3 %   -22 %

Selling, general and administrative

     5,417      4,597      4,710    18 %   -2 %

Impairment of long lived asset

     —        —        2,413      -100 %
                                 

Total operating expenses

   $ 14,131    $ 13,522    $ 16,855    5 %   -20 %

The decrease in cost of product revenue of $337,000 in fiscal 2006 is attributable to a decrease in royalty and amortization fees of $1,236,000 associated with SecreFlo®, partially offset by an increase of $688,000 in direct materials and increased personnel costs of $189,000. This reduction in SecreFlo® related expenses is due to the settlement agreement in May of 2005 with ChiRhoClin while the increase in material costs and personnel is a result of higher sale levels. During fiscal 2005, the increase in costs of product revenue of $640,000 was directly attributable to higher product sales and a charge of approximately $200,000 for excess and expired inventory. Gross profit is positively impacted in periods when product sales are higher because there is more absorption of fixed costs. We anticipate that higher product sales and the aforementioned settlement with ChiRhoClin will result in the similar margins for fiscal 2007.

Research and development expenses for fiscal 2006, 2005 and 2004 were approximately $5,163,000, $5,037,000 and $6,484,000, respectively. Research and development costs primarily include costs of internal personnel, external research collaborations, clinical trials and the costs associated with the manufacturing and testing of clinical materials. We currently have ongoing research and development programs that support our product candidates of secretin and uridine. In addition, we are involved with a number of early stage programs that may or may not be further developed. Due to the small size of the Company and the fact that these various programs share personnel and fixed costs such as facility costs, depreciation, and supplies, we do not track our expenses by program.

Each of our research and development programs is subject to risks and uncertainties, including the requirement to seek regulatory approvals that are outside of our control. For example, our clinical trials may be subject to delays based on our inability to enroll patients at the rate that we expect to meet the schedule for our planned clinical trials. Moreover, the product candidates identified in these research programs, particularly in our early stage programs must overcome significant technological, manufacturing and marketing challenges before they can be successfully commercialized. For example, results from our preclinical animal models may not be replicated in our clinical trials with humans. As a result of these risks and uncertainties, we are unable to predict with any certainty the period in which material net cash inflows from such projects could be expected to commence or the completion date of these programs.

These risks and uncertainties also prevent us from estimating with any certainty the specific timing and future costs of our research and development programs, although historical trends within the industry suggest that expenses tend to increase in later stages of development. Collaborations with commercial vendors and academic researchers accounted for 36%, 37% and 43% of our research and development expenses in the fiscal years ended March 31, 2006, 2005 and 2004, respectively. The outsourcing of such services provides us flexibility to discontinue or increase spending depending on the success of our research and development programs.

During fiscal 2006, research and development expenses increased by $126,000. This increase is largely attributable to higher clinical trial expenses of $192,000, increased personnel expenses of $124,000 and increased license expense of $59,000, offset by decreased expenses associated with our external research of $222,000. During fiscal 2005, costs of clinical trials decreased by $736,000, clinical materials decreased by $124,000, external collaborations costs decreased by $90,000 and staffing costs decreased by $239,000.

Table of Contents

Future research and development expenses are dependent on a number of variables, including the cost and design of clinical trials and external costs such as manufacturing of clinical materials. We expect our research and development expenses in fiscal 2007 to increase due to an increase in clinical trials and may further increase if we acquire an additional product candidate.

Selling, general and administrative expenses (SG&A) include the associated costs with selling our commercial products and costs required to support our research and development efforts including legal, accounting, patent, shareholder services and other administrative functions. In addition, SG&A expenses have historically included costs associated with various litigation matters.

During fiscal 2006, SG&A costs increased by approximately $820,000. This increase was a result of increased personnel expenses of $291,000, increased professional expenses of $271,000, increased legal expenses of $176,000 and increased marketing costs of $27,000. During fiscal 2005, SG&A costs decreased by approximately $113,000, a result of decreased costs in shareholder services of $212,000 and marketing expenses of $174,000 offset by increased legal costs of $292,000 and external costs relating to compliance with the Sarbanes-Oxley Act of 2002 of $151,000. We expect SG&A expenses to increase in FY2007 due to litigation and personnel expenses.

Impairment of long-lived asset

During fiscal 2004, we recognized a non-cash charge of $2,413,000 associated with the termination of the SecreFlo® license agreement. (See “Legal Proceedings” and Note 3 of Notes to Financial Statements.)

Investment income

Investment income includes income earned on invested cash balances. Investment income for fiscal 2006, 2005 and 2004 was approximately $750,000, $428,000 and $390,000, respectively. The increase of $322,000 or 75% in fiscal 2006 is attributable to a higher interest rates compared to fiscal 2005. The increase of $38,000 or 10% in fiscal 2005 was attributable to higher interest rates earned as compared to fiscal 2004. We expect interest income to vary based on changes in the amount of funds invested and fluctuation of interest rates.

Other income

During the year ended March 31, 2006, Repligen entered into a Settlement Agreement with ChiRhoClin, Inc., in full settlement of their arbitration proceedings. As a result of the settlement, we determined that we were not required to pay approximately $1,170,000 of previously accrued but unremitted royalties to ChiRhoClin related to SecreFlo® sales from February 2004 to March 2005. This amount, which was accrued at March 31, 2005, was reversed at the time of settlement and is recorded as other income in the fiscal year ended March 31, 2006. Other income for the year ended March 31, 2005 consists of $750,000 in proceeds from a legal settlement from Pro-Neuron received in November 2004.

Liquidity and Capital Resources

We have financed our operations primarily through sales of equity securities and revenues derived from product sales and grants. Our revenue for the foreseeable future will be limited to our product revenue related to Protein A and SecreFlo®. Given the uncertainties related to pharmaceutical product development, we are currently unable to reliably estimate when, if ever, our therapeutic product candidates or our patents will generate revenue and cash flows.

At March 31, 2006 we had cash and marketable securities of $23,408,000 compared to $23,523,000, at March 31, 2005. Restricted cash of $200,000 is not included in cash and marketable securities for either 2006 or 2005.

Operating Activities

In fiscal 2006, our operating activities provided cash of $415,000 as a result of our net profit of $697,000 and non-cash charges such as depreciation, amortization and stock compensation charges. Sources of cash included a decrease in accounts receivable of approximately $176,000 due to improved cash collections and a reduction in prepaid expenses of approximately $134,000. Uses of cash included an increase in inventories of approximately $832,000 which was a result of purchases related to a manufacturing process conversion and an increase in accrued liabilities of approximately $328,000.

In fiscal 2005, our cash used in operations decreased from 2004 levels as a result of our reduced net loss before non-cash charges such as depreciation, amortization and stock compensation charges. This reduced loss benefited from the significant increase in our product sales, the receipt of $750,000 from a legal settlement and reduced research and development expenses. Increased product sales in fiscal 2005 also reduced our inventory levels. Accounts receivable decreased from 2004 levels due to improved cash collections. In addition, as a result of a dispute with our supplier of SecreFlo® we recorded a royalty obligation but did not pay, therefore, increasing accrued expenses.

Investing Activities

In fiscal 2006, our purchases of property, plant and equipment were $877,000 of which $142,000 was financed through capital leases. We expect to incur greater than $1,000,000 of capital investment primarily to expand our Protein A manufacturing facility in the next twelve months. In fiscal 2005, our purchases of property and equipment were $86,000 of which $34,000 was financed through capital leases. Purchases and redemptions of marketable securities account for the remainder of the fluctuation during fiscal 2006 and fiscal 2005. We generally place our marketable security investments in high quality credit instruments as specified in our investment policy guidelines.

Financing Activities

In fiscal 2006, exercises of stock options provided cash proceeds of $340,000. In fiscal 2005, exercises of stock options provided cash proceeds of $31,000, a decrease from fiscal year 2004’s proceeds of $155,000.

Off-Balance Sheet Arrangements

We do not have any special purpose entities or off-balance sheet financing arrangements.

(1) The above amounts represent principal payments only while principal and interest are payable through a fixed monthly payment of approximately $4,000 and a fixed annual payment of $52,000.
(2) This amount represents minimum commitments due under a third-party manufacturing agreement.
(3) These amounts include payments for license, supply and consulting agreements.

Capital Requirements

Our future capital requirements will depend on many factors, including the following:

 

    the success of our clinical studies;

 

    the scope of and progress made in our research and development activities;

 

    our ability to acquire additional product candidates;

 

    the success of any proposed financing efforts; and

 

    the ability to sustain sales and profits of our commercial products.

Absent an acquisition of a product candidate, we believe our current cash balances are adequate to meet our cash needs for at least the next twenty-four months. We expect to incur an increased level of expense in fiscal 2007 compared to those incurred in fiscal 2006. This is due to anticipated increases in clinical study expenses and legal fees for litigation in process currently, as well as increased personnel expenses. Our future capital requirements include, but are not limited to, continued investment in our research and development programs, capital expenditures primarily associated with purchases of equipment and continued investment in our intellectual property portfolio.

We plan to continue to invest in key research and development activities. After the discontinuation of our Phase III trial in autism, we began a review of technology and product candidates that would complement our existing portfolio of development programs. We continue to seek to acquire such potential assets that may offer us the best opportunity to create value for our shareholders. In order to acquire such assets, we may need to seek additional financing to fund these investments. This may require the issuance or sale of additional equity or debt securities. The sale of additional equity may result in additional dilution to our stockholders. Should we need to secure additional financing to acquire a product, fund future investment in research and development, or meet our future liquidity requirements, we may not be able to secure such financing, or obtain such financing on favorable terms because of the volatile nature of the biotechnology marketplace.

Net Operating Loss Carryforwards

At March 31, 2006, we had net operating loss carryforwards of approximately $106,290,000 and research and development credit carryforwards of approximately $5,590,000 to reduce future federal income taxes, if any. The net operating loss and tax credit carryforwards have expired and will continue to expire at various dates,

Table of Contents

beginning in fiscal year 2007, if not used. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service and may be limited in the event of certain changes in the ownership interest of significant stockholders. We did not record a tax provision in the fiscal year 2006 statement of operations as we did not generate taxable income.

Effects of Inflation

Our assets are primarily monetary, consisting of cash, cash equivalents and short-term investments. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture and fixtures and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources.

Recent Accounting Pronouncements

Stock-Based Compensation

In December 2004, the FASB issued SFAS No. 123R, “Share-Based Payment—An Amendment of FASB Statements No. 123 and 95 (“SFAS No. 123R”)”, which requires all companies to measure compensation cost for all share-based payments, including employee stock options, at fair value, effective for public companies for annual periods beginning after November 15, 2005. Generally, the approach in SFAS No. 123R is similar to the approach described in SFAS No. 123. However, SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative.

As of April 1 2006, we plan on adopting SFAS No. 123(R) using the “modified-prospective method,” which is a method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of Statement No. 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of SFAS No. 123(R) that remain unvested on the effective date. We apply the Black-Scholes valuation model in determining the fair value of share-based payments to employees, which will then be amortized on a straight-line basis. We expect the adoption of SFAS No. 123(R) to have a material effect on our financial statements, in the form of additional compensation expense, on a quarterly and annual basis. We expect to record total compensation expense of approximately $810,000 during fiscal 2007 as a result of the adoption of SFAS No. 123(R). However, the actual expense recorded as a result of the adoption of SFAS No. 123(R) may differ materially from the $810,000 as a result of changes in the number of options granted annually by Repligen’s Board of Directors, the price of our common stock, volatility of our stock price, the estimate of the expected life of options granted and risk free interest rates as measured at the grant date.

Accounting Changes and Error Corrections

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FASB Statement No. 3” (SFAS No. 154). SFAS No. 154 changes the requirements for the accounting for and reporting of a change in accounting principle. SFAS No. 154 applies to all voluntary changes in accounting principle. It also applies to changes required by an accounting pronouncement in the unusual instance that the pronouncement does not include specific transition provisions. When a pronouncement includes specific transition provisions, those provisions should be followed. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in fiscal years after the date the statement was issued. The Company will apply the provisions of SFAS No. 154 starting January 1, 2006 on a prospective basis. The Company does not believe that there will be a material effect on its financial condition or results of operations from the adoption of the provisions of SFAS No. 154.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have investments in commercial paper, U.S. Government and agency securities as well as corporate bonds and other debt securities. As a result, we are exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer or otherwise.

We generally place our marketable security investments in high quality credit instruments, as specified in our investment policy guidelines. A hypothetical 100 basis point decrease in interest rates would result in an approximate $101,000 decrease in the fair value of our investments as of March 31, 2006. However, the conservative nature of our investments mitigates our interest rate exposure, and our investment policy limits the amount of our credit exposure to any one issue, issuer, (with the exception of U.S. treasury obligations) and type of instrument. We do not expect any material loss from our marketable security investments due to interest rate fluctuations and therefore believe that our potential interest rate exposure is limited. We intend to hold these investments to maturity, in accordance with our business plans.

Item 9A. CONTROLS AND PROCEDURES.

(a) Disclosure Controls and Procedures.

The Company’s management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, our chief executive officer and chief financial officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, on a timely basis, and is accumulated and communicated to the Company’s management, including the Company’s chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Management’s Annual Report on Internal Control Over Financial Reporting.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles and includes those policies and procedures that:

 

    pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

 

   

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

    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. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the company’s internal control over financial reporting as of March 31, 2006. In making this assessment, management used the criteria established in Internal Control-Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management concluded that, as of March 31, 2006 our internal control over financial reporting is effective based on those criteria. Our management’s assessment of the effectiveness of our internal control over financial reporting as of March 31, 2006 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report appearing in Item 9a of this Form 10-K.

(c) Attestation Report of the Independent Registered Public Accounting Firm.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Repligen Corporation

We have audited management’s assessment, included in the accompanying Report of Management on Internal Control Over Financial Reporting, that the Company maintained effective internal control over financial reporting as of March 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Repligen Corporation’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. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of 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, evaluation of management’s assessment, testing and evaluating the design and operating effectiveness of internal control 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 the 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 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, management’s assessment that the Company maintained effective internal control over financial reporting as of March 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2006, based on the COSO criteria.

We also have audited, in accordance with the standards the Public Company Accounting Oversight Board (United States), the balance sheets of Repligen Corporation as of March 31, 2006 and 2005, and the related statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended March 31, 2006 and our report dated June 8, 2006, expressed an unqualified opinion thereon.

(1) These amounts represent hypothetical gains that could be achieved from the exercise of respective options and the subsequent sale of the Common Stock underlying such options if the options were exercised immediately prior to the end of the option term. These gains are based on assumed rates of stock price appreciation of 5% and 10% compounded annually from the date the respective options were granted to their expiration dates. The gains shown are net of the option exercise price, but do not include deductions for taxes or other expenses associated with the exercise of the options or sale of the underlying shares. The actual gains, if any, on the stock option exercises will depend on the future performance of the Common Stock, the optionholder’s continued employment through the option period, the date on which the options are exercised, and the date on which the underlying shares of Common Stock are sold. These rates of appreciation are mandated by the rules of the SEC and do not represent Repligen’s estimate or projection of the future Common Stock price.
(2) The option holder may exercise the option to purchase 20% of these shares of Common Stock as of May 13, 2006 and an additional 20% per year on the next four anniversaries thereof.
(3) The option holder may exercise the option to purchase 25% of these shares of Common Stock as of February 27, 2007 and an additional 25% on the next three anniversaries thereof.

(3) The dollar values have been calculated by determining the difference between the fair market value of the securities underlying the options and the exercise price of the options. The fair market value of in-the-money options was calculated on the basis of the closing price per share for Common Stock on the Nasdaq National Market of $3.70 on March 31, 2006. Of the 1,280,000 options outstanding and held by the Named Executive Officers, 732,000 of these options were in the money as of March 31, 2006.

Compensation of Directors

Drs. Schimmel and Rich, the Co-Chairmen of the Board of Directors, are compensated pursuant to consulting agreements described below and receive no separate compensation for attendance at meetings or otherwise as directors.

Under the terms of the Plan as currently in effect, each non-employee director, beginning on September 10, 2003, is granted an option to purchase 15,000 shares of Common Stock at an option price equal to the fair market value of the Common Stock on the date of grant, determined in accordance with the terms of the Plan (the “Annual Board Options”). These options vest in full on the first anniversary of the date of the grant, provided such person is still a director on such anniversary. Additionally, each newly-elected, non-employee director who joins the Board is entitled to receive an option to purchase 24,000 shares of Common Stock on the date he or she joins the Board (an “Initial Board Option” and together with the Annual Board Options, the “Board Options”). These Initial Board Options vest equally over a three-year period from the date of grant. Board Options have a term of ten years, subject to early termination in the event of death, removal or resignation from the Board. No director would be entitled to receive Board Options covering more than an aggregate of 150,000 shares of Common Stock, excluding expired unexercised options.

Each non-employee director (other than Drs. Rich and Schimmel) receives $5,000 per quarter and $1,500 plus expenses for each board meeting they attend. In addition, the Chairman of the Audit Committee receives $2,500 plus expenses for each meeting attended and each other Audit Committee member receive $1,000 plus expenses for each meeting in which they participate.

Repligen paid Drs. Schimmel and Rich $49,200 and $43,200, respectively, during the fiscal year ended March 31, 2006 pursuant to consulting agreements, which have similar terms. These agreements are automatically extended for successive one-year terms unless terminated by either party at least 90 days prior to the next anniversary date. During the term of each of the consulting agreements, and for a period of up to one year thereafter, if Repligen pays the director a lump sum (equal to 90% of the consulting fees paid for the preceding 12 months), such director will not have a business relationship with companies engaged in a business substantially similar to Repligen or with companies that compete with Repligen, except under limited circumstances. Dr. Schimmel’s agreement continues until September 30, 2006 and Dr. Rich’s agreement continues until October 31, 2006. Drs. Schimmel and Rich have advised Repligen that they have no present intention of terminating their agreements.

Executive Employment Agreements

On March 14, 1996, Repligen entered into a letter of agreement with Drs. Herlihy, Rusche, and Witt in connection with Repligen’s acquisition and merger with Glycan Pharmaceuticals, Inc. (the “Herlihy Agreement,” the “Rusche Agreement,” and the “Witt Agreement,” respectively). Under the terms of the Herlihy Agreement, Dr. Herlihy is entitled to a minimum salary of $160,000 per annum, subject to periodic increases at the discretion of the Board of Directors. Additionally, Dr. Herlihy is eligible for participation in all of Repligen’s welfare, profit sharing, retirement and savings plans on the same basis as other employees of Repligen. Dr. Herlihy received a stock option to purchase 100,000 shares of the Common Stock at $1.25 per share, vesting at 20% per annum over five years pursuant to the Herlihy Agreement. Dr. Herlihy’s employment may be terminated, with or without cause, by either party upon 30 days prior written notice. In such event, Dr. Herlihy would be entitled to continue receiving his salary for a period of eight months or until he finds other employment, whichever occurs first. In addition, 50% of any unvested options owned by Mr. Herlihy vest immediately upon notice of termination of employment or a change in control of Repligen.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee currently consists of Dr. Schimmel and Mr. Hennessey. No member of the Compensation Committee is a current or former employee of Repligen. There are no Compensation Committee interlocks between Repligen and any other entities involving any of the executive officers or directors of such entities. No interlocking relationship exists between any member of our Board of Directors or our Compensation Committee and any member of the Board of Directors or compensation committee of any other company and no such interlocking relationship has existed in the past.

Compensation Committee Report To Stockholders

The Compensation Committee is comprised of two independent members of the Board of Directors. As stated above, the Compensation Committee is responsible (among other duties and responsibilities) for (1) discharging the Board’s responsibilities relating to the compensation of the Company’s executive officers (including the Named Executive Officers), (2) administering the Company’s incentive compensation and stock plans (currently, the Amended and Restated 2001 Repligen Corporation Stock Plan (the “Plan”), and (3) producing an annual report on executive compensation for inclusion in the Company’s proxy statement in accordance with applicable rules and regulations. The Committee is responsible for reviewing and making recommendations to management on company-wide compensation programs and practices, for taking final action with respect to the individual salary, bonus and equity arrangements of the Company’s Chief Executive Officer and other senior officers, and for recommending, subject to approval by the full Board, new equity-based plans and any material amendments thereto (including increases in the number of shares of Common Stock available for grant as options or otherwise thereunder) for which stockholder approval is required or desirable.

Compensation Philosophy

The ultimate goal of Repligen’s compensation program is to motivate each employee to enhance stockholder value, to provide a fair reward for this effort, and to stimulate each employee’s professional and personal growth. Key elements of this philosophy include:

 

    salaries that are competitive with other biopharmaceutical and biotechnology companies with which the Company competes for talent, determined by comparing the Company’s pay practices with these companies; and

 

38


Table of Contents
    equity based incentives for all permanent employees to ensure that they are motivated over the long-term to respond to the Company’s business challenges and opportunities as owners and not just as employees.

Executive Compensation

The Company’s executive compensation consists of three key components: base salary, annual bonus awards and stock incentives. Each of these components is intended to complement the other, and taken together, to satisfy the Company’s compensation objectives. The Compensation Committee’s objective is to set executive compensation at competitive levels with other biopharmaceutical and biotechnology companies.

Each executive officer (except the Chief Executive Officer whose performance is reviewed by the Compensation Committee) has an annual performance review with the Chief Executive Officer who makes recommendations on salary increases, promotions and stock option grants to the Compensation Committee. The recommended salary increases are based on the average salary increases expected in the biotechnology industry. In general, the Committee has set total executive compensation at levels that are within the 50th to 60th percentile based upon independent industry surveys.

Annual cash bonuses are voted after the end of each fiscal year and calculated as a percentage of an executive officer’s base salary as determined by the criteria set forth below. Stock options are also awarded from time to time based upon the same criteria and are intended both to retain and reward the executive and to provide further incentive for him or her to continue contributing to the long-term success of Repligen.

Performance Criteria

Since Repligen is still in the process of developing its proprietary products and because of the highly volatile nature of biotechnology stocks in general, it is not appropriate to use the traditional performance standards, such as profit levels and stock performance, to measure the success of Repligen and an individual’s contribution to that success.

Accordingly, the compensation of executive officers (including the Chief Executive Officer) is based, for the most part, on the achievement of certain goals by Repligen as a whole and the individual (and his or her business unit) concerned. The Compensation Committee therefore examines three specific areas in formulating the compensation packages of its the Named Executive Officers. Criteria and specific goals within each category are as follows:

Company Performance:

 

    The extent to which key research, clinical, product manufacturing, product sales and financial objectives of Repligen have been met during the preceding fiscal year;

 

    The development, acquisition and licensing of key technology; and

 

    The achievement by Repligen of certain milestones, whether specified in agreements with third party collaborators or determined internally.

Executive Performance:

 

    An executive’s involvement in and responsibility for the development and implementation of strategic planning and the attainment of strategic objectives of Repligen;

 

    The participation by an executive in the relationship between Repligen and the investment community;

 

    The involvement of an executive in personnel recruitment, retention and morale; and

 

    The responsibility of the executive in working within budgets, controlling costs and other aspects of expense management.

 

39

Other Factors:

 

    The necessity of being competitive with companies in the pharmaceutical and biotechnology industries, taking into account relative company size, stage of development, performance and geographic location as well as individual responsibilities and performance.

Dr. Herlihy’s Compensation

Dr. Herlihy is eligible to participate in the same executive compensation plans available to Repligen’s other executive officers. In May of 2006, Dr. Herlihy’s salary level was reviewed and the Committee decided to increase his annual salary to $334,000 and the Committee decided to award a cash bonus of $66,744. The Committee set Dr. Herlihy’s total compensation in accordance with Repligen’s executive compensation philosophy, based on his performance against the performance criteria outlined above (including his contributions to Repligen’s results during the fiscal year ended March 31, 2006 and the importance of his leadership to Repligen’s future success) and believes that his compensation is competitive, fair, and consistent with Repligen’s results for the fiscal year ended March 31, 2006.

Item 14. PRINCIPAL ACCOUNTING FEES AND SERVICES

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected the firm of Ernst & Young LLP (“Ernst & Young”), independent certified public accountants, to serve as independent auditors for the fiscal year ending March 31, 2007. Ernst & Young has served as the Company’s independent certified public accountants since 2002. In accordance with standing policy, Ernst & Young LLP periodically changes the personnel who work on the audit of Repligen.

Fees

The following sets forth the aggregate fees billed by Ernst & Young to the Company during the fiscal year ended March 31, 2006 and 2005:

Audit Fees

Fees paid for audit services were approximately $190,000 for the fiscal year ended March 31, 2006 and $169,000 for fiscal year ended March 31, 2005. These included fees associated with the annual audit, the reviews of the Company’s quarterly reports on Form 10-Q, and fees related to filings with the SEC. Included in these fees, $90,000 and $93,000 in FY06 and FY05 respectively were for audit services related to our compliance with Section 404 of the Sarbanes-Oxley Act of 2002 regarding our internal control over financial reporting.

Audit Related Fees

Ernst & Young LLP billed no fees for the last two years for assurance and related services that are reasonably related to the performance of the audit or review of the financials and are not otherwise reported above.

Tax Fees

Total fees paid for tax services was $12,500 for fiscal year ended March 31, 2006 and $12,500 for fiscal year ended March 31, 2005, consisting of tax compliance and preparation fees.

All Other Fees

Ernst & Young LLP billed no additional fees for the fiscal year ended March 31, 2006 and 2005.

The Audit Committee of the Board of Directors has implemented procedures under the Company’s Audit Committee Pre-Approval Policy for Audit and Non-Audit Services (the “Pre-Approval Policy”) to ensure that all audit and permitted non-audit services provided to the Company are approved by the Audit Committee. Specifically, the Audit Committee pre-approves the use of Ernst & Young for specific audit and non-audit services, within approved monetary limits. If a proposed service has not been pre-approved pursuant to the Pre-Approval Policy, then it must be specifically pre-approved by the Audit Committee before Ernst & Young may provide it. Any pre-approved services exceeding the limits pre-approved by the Audit Committee must again be pre-approved by the Audit Committee. Following the effectiveness of the rules regarding audit committee pre-approval, all of the audit-related, tax and all other services provided by Ernst & Young to the Company in the fiscal year ended March 31, 2006 were approved by the Audit Committee by means of a specific pre-approval or pursuant to the procedures contained in the Pre-Approval Policy. All non-audit services provided in the fiscal year ended March 31, 2006 were reviewed with the Audit Committee, which concluded that the provisions of such services by Ernst & Young was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions.

In connection with the audits for the period ending March 31, 2006, there were no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP, would have caused them to refer to such disagreement in connection with their report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Repligen Corporation

We have audited the accompanying balance sheets of Repligen Corporation as of March 31, 2006 and 2005, and the related statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended March 31, 2006. These financial statements 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 financial position of Repligen Corporation as of March 31, 2006 and 2005, and the results of its operations, and its cash flows for each of the three years in the period ended March 31, 2006, in conformity with U.S. generally accepted accounting principles.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Repligen Corporation’s internal control over financial reporting as of March 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated June 8, 2006 expressed an unqualified opinion thereon.

REPLIGEN CORPORATION

NOTES TO FINANCIAL STATEMENTS

 

1. Organization and Nature of Business

Repligen Corporation is a biopharmaceutical company focused on the development of novel therapeutics for the treatment of diseases of the central nervous system. A number of drug development programs are currently being conducted to evaluate the Company’s naturally occurring drug candidates in diseases such as schizophrenia, bipolar disorder and neurodegeneration. In addition, Repligen sells two commercial products, Protein A for monoclonal antibody purification and SecreFlo® for assessment of pancreatic disorders.

The Company’s business strategy is to deploy the profits from its commercial products and any revenue that it may receive from its patents to enable the Company to invest in the development of product candidates in the treatment area of neuropsychiatric diseases.

The Company is subject to a number of risks typically associated with companies in the biotechnology industry. Principally those risks are associated with the Company’s dependence on collaborative arrangements, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with the U.S. Food and Drug Administration and other governmental regulations and approval requirements, as well as the ability to grow the Company’s business and obtain adequate funding to finance this growth.

 

2. Summary of Significant Accounting Policies

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 reporting period. Actual results could differ from those estimates.

Reclassifications

The Company has reclassified certain prior-year information to conform to the current year’s presentation. Interest receivables of $317,328 and $393,767 were reclassified from marketable securities to other current assets on the balance sheet and statement of cash flows in FY2005 and FY2004 respectively. The Company is also presenting cost of revenue as an operating expense in the statement of operations in FY 2005 and 2004.

Revenue Recognition

The Company applies Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) to its revenue arrangements. The Company generates product revenues from the sale of its Protein A products to customers in the pharmaceutical and process chromatography industries, and from the sale of SecreFlo® to hospital-based gastroenterologists. In accordance with SAB No. 104, the Company recognizes revenue related to product sales upon delivery of the product to the customer as long as there is persuasive evidence of an arrangement, the price is fixed or determinable and collection of the related receivable is reasonably assured.

During the fiscal year ended March 31, 2006, the Company received $310,000 of cash from a sponsored research and development project under an agreement with the Stanley Medical Research Institute. Research revenue is recognized for costs plus fixed-fee contracts as costs are incurred. During fiscal 2004, the Company generated non-product revenues from sponsored research and development projects under a Small Business Innovation Research (“SBIR”) Phase I grant. Research expenses in the accompanying statements of operations include funded and unfunded expenses. Additionally, during fiscal year 2006, the Company earned and recognized approximately $72,000 in royalty revenue from ChiRhoClin, Inc.

Risks and Uncertainties

The Company evaluates its operations periodically to determine if any risks and uncertainties exist that could impact its operations in the near term. The Company does not believe that there are any significant risks which have not already been disclosed in the financial statements. However, the Company does rely on a single supplier for SecreFlo® materials. (See Note 11). Although alternate sources of supply exist for these items, loss of certain suppliers could temporarily disrupt operations. The Company attempts to mitigate these risks by working closely with key suppliers, identifying alternate sources and developing contingency plans.

Comprehensive Income

The Company applies Statement of Financial Accounting Standards (SFAS) No. 130, “Reporting Comprehensive Income.” SFAS No. 130 requires disclosure of all components of comprehensive income on an annual and interim basis. Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from nonowner sources. The Company’s comprehensive income (loss) is equal to its reported net income (loss) for all periods presented.

Cash Equivalents & Marketable Securities

The Company applies SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” At March 31, 2006, the majority of the Company’s cash equivalents and marketable securities are classified as held-to-maturity investments as the Company has the positive intent and ability to hold to maturity. As a result, these investments are recorded at amortized cost. Marketable securities are investments with original maturities of greater than 90 days. Long-term marketable securities are investment grade securities with maturities of greater than one year.

At March 31, 2006 marketable securities also include investment grade auction rate securities, which provide higher yields than money market and other cash equivalent investments. Auction rate securities have long-term underlying maturities, but have interest rates that are reset every 90 days or less, at which time the securities can typically be purchased or sold, which creates a highly liquid market for these securities. The Company does not intend to hold these securities to maturity, but rather to use the securities to provide liquidity as necessary. Auction rate securities are classified as available-for-sale and reported at fair value. Due to the reset feature and their carrying value equaling their fair value, there are no gross unrealized gains or losses from these short-term investments.

Cash equivalents and marketable securities consist of the following at March 31, 2006 and 2005:

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments which represent cash, marketable securities, and accounts receivable generally approximate fair value due to the short-term nature of these instruments.

Concentrations of Credit Risk and Significant Customers

Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash and cash equivalents, marketable securities and accounts receivable. The Company’s cash equivalents and marketable securities are invested in financial instruments with high credit ratings and by policy limits the amount of its credit exposure to any one issue, issuer, (with the exception of U.S. treasury obligations) and type of instrument. At March 31, 2006, the Company has no items such as those associated with foreign exchange contracts, options contracts or other foreign hedging arrangements.

Concentration of credit risk with respect to accounts receivable is limited to customers to whom the Company makes significant sales. The Company maintains reserves for the potential write-off of accounts receivable. To date, the Company has not written off any significant accounts. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition.

Revenue from significant customers as a percentage of the Company’s total revenue is as follows:

 

     Years Ended March 31,  
     2006      2005      2004  

Customer A

   49 %    54 %    43 %

Customer B

   * %    10 %    11 %

Customer C

   26 %    13 %    * %

* Represents less than 10% of total revenue.

Significant accounts receivable balances as a percentage of the Company’s total trade accounts receivable balances are as follows:

 

     As of March 31,  
       2006          2005    

Customer A

   25 %    51 %

Customer B

Customer C

   11 %    13 %

Customer D

   25 %    * %

* Did not represent a significant percentage of total trade accounts receivable at March 31, 2005.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market. Work-in-process and finished goods inventories consist of material, labor, outside processing costs and manufacturing overhead. Inventories at March 31, 2006 and 2005 consist of the following:

 

     As of March 31,
     2006    2005

Raw materials

   $ 600,948    $ 172,336

Depreciation and Amortization

Depreciation and amortization are calculated using the straight-line method over the estimated useful life of the asset as follows:

 

Description

  

Estimated Useful Life

Leasehold improvements

   Shorter of term of the lease or estimated useful life

Equipment

   3-5 years

Furniture and fixtures

   5 years

The Company recorded depreciation and amortization of property, plant and equipment expense of $398,434, $363,738 and $376,505 in 2006, 2005 and 2004, respectively. Depreciation of assets under capital leases is included in depreciation and amortization. The amount of depreciation recorded for assets under capital lease agreements for fiscal years 2006, 2005, and 2004 was $16,268, $4,721 and $0, respectively.

Earnings Per Share

The Company applies the provisions of Statement of Financial Accounting Standard (“SFAS”) No. 128, “Presenting Earnings Per Share.” Basic earnings per share for the periods ended March 31, 2006, 2005 and 2004 were computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method in accordance with SFAS No. 128. Dilutive potential common shares include outstanding stock options.

Basic and diluted weighted average shares outstanding were as follows:

 

     Twelve Months Ended March 31,
     2006    2005    2004

Weighted average common shares outstanding

   30,125,041    30,061,812    29,686,373

Dilutive common stock options

   565,900    —      —  
              

Weighted average common shares outstanding, assuming dilution

   30,690,941    30,061,812    29,686,373
              

For the year ended March 31, 2006, options to purchase 955,400 shares, were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares.

Diluted weighted average shares outstanding for 2005 and 2004 do not include the potential common shares from warrants and stock options because to do so would have been antidilutive. Accordingly, basic and diluted net loss per share is the same. The number of potential common shares excluded from the calculation of diluted earnings per share during the years ended March 31, 2005 and 2004 was 2,166,900 and 2,305,746, respectively.

Segment Reporting

The Company applies SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” SFAS No. 131 establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information for those segments to be presented in interim financial reports issued to stockholders. SFAS No. 131 also establishes standards for related disclosures about products and services and geographic areas. The chief operating decision maker, or decision-making group, in making decisions how to allocate resources and assess performance, identifies operating segments as components of an enterprise about which separate discrete financial information is available for evaluation. To date, the Company has viewed its operations and manages its business as one operating segment. As a result, the financial information disclosed herein represents all of the material financial information related to the Company’s principal operating segment.

Stock Based Compensation

The Company accounts for its stock-based compensation under SFAS No. 123 “Accounting for Stock-Based Compensation.” The Company continues to apply the intrinsic value method proscribed by APB No. 25 for employee stock options awards and elected the disclosure-only alternative for the same under SFAS No. 123. The Company follows the disclosure provisions of Statement of Financial Accounting Standards No. 148 (SFAS 148), “Accounting for Stock-Based Compensation—Transition and Disclosure, and amendment of FASB Statement No. 123.” SFAS 148 requires prominent disclosures in both annual and interim financial statements regarding the method of accounting for stock-based employee compensation and the effect of the method used to report results.

The Company has computed the pro forma disclosures required under SFAS Nos. 123 and 148 for all stock options granted to employees using the Black-Scholes option-pricing model prescribed by SFAS No. 123. The assumptions used and the weighted average information for the years ended March 31, 2006, 2005 and 2004 are as follows:

 

     Years Ended March 31,  
     2006      2005      2004

Recent Accounting Pronouncements

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued FASB Statement No. 123 (revised 2004), “Share-Based Payment,” which is a revision of SFAS No. 123. Statement 123(R) supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and amends FASB Statement No. 95, “Statement of Cash Flows.” Generally, the approach in Statement 123(R) is similar to the approach described in SFAS 123. However, Statement 123(R) requires all share-based payments to employees, including grants of employee share options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative.

The Company will adopt Statement 123(R) on April 1, 2006.

Statement 123(R) permits public companies to adopt its requirements using one of two methods:

1. A “modified prospective” method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of Statement 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of Statement 123 for all awards granted to employees prior to the effective date of Statement 123(R) that remain unvested on the effective date; or

2. A “modified retrospective” method which includes the requirements of the modified prospective method described above, but also permits entities to restate based on the amounts previously recognized under Statement 123 for purposes of pro forma disclosures either (a) all prior periods presented or (b) prior interim periods of the year of adoption.

The Company has determined to utilize the “modified prospective” method in adopting SFAS 123(R). The Company currently anticipates recognizing approximately $800,000 in the fiscal year ending March 31, 2007, approximately $600,000 in the fiscal year ending March 31, 2008 and $600,000 thereafter of compensation expense related to unvested share options currently held by employees as a result of adopting SFAS 123(R). Compensation expense could be increased to the extent additional share options are granted in the future.

Had the Company adopted SFAS 123(R) in prior fiscal years, the impact of that standard would have approximated the impact of SFAS 123 as described in the disclosure of pro forma net income (loss) and earnings per share in Note 2.

Table of Contents

The FASB recently issued Statement No. 154, “Accounting Changes and Error Corrections,” (SFAS 154), which is a replacement of APB Opinion No. 20, “Accounting Changes,” and FASB Statement No. 3, “Reporting Accounting Changes in Interim Financial Statements.” (SFAS 3). SFAS 154 applies to all voluntary changes in accounting principle, and changes the requirements for accounting for and reporting of a change in accounting principle. SFAS 154 requires retrospective application to prior periods’ financial statements of a voluntary change in accounting principle unless it is impracticable. APB 20 previously required that most voluntary changes in accounting principle be recognized by including in net income of the period of the change the cumulative effect of changing to the new accounting principle. SFAS 154 requires that a change in method of depreciation, amortization, or depletion for long-lived, non-financial assets be accounted for as a change in accounting estimate that is effected by a change in accounting principle. APB 20 previously required that such a change be reported as a change in accounting principle. SFAS 154 carries forward many provisions of APB 20 without change, including the provisions related to the reporting of a change in accounting estimate, a change in the reporting entity, and the correction of an error. SFAS 154 also carries forward the provisions of SFAS 3 that govern reporting accounting changes in interim financial statements. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Earlier application is permitted for accounting changes and corrections of errors made occurring in fiscal years beginning after June 1, 2005. SFAS 154 does not change the transition provisions of any existing accounting pronouncements, including those that are in a transition phase as of the effective date of SFAS 154.

 

3. Long-Lived Assets

During 2002, under the terms of its September 1999 Licensing Agreement with ChiRhoClin, Inc. Repligen made a milestone payment to ChiRhoClin that consisted of $1,250,000 in cash and 696,223 shares of its common stock. The Company recorded the fair value of the shares issued, $2,576,025, and the cash paid of $1,250,000, as a long-term intangible asset. Beginning in April 2002, the Company began to amortize this intangible asset to cost of revenue over the remaining term of the license, approximately seven years. The Company amortized $510,130 during the year ended March 31, 2004.

The Company reviews its long-term assets for impairment at each reporting period in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”. At March 31, 2004, as a result of a dispute with ChiRhoClin, the Company recorded an impairment charge of $2,413,244 in its statements of operations for the year ended March 31, 2004. During the year ended March 31, 2005, the Company amortized the remaining balance of this long-term intangible asset of $392,520 to cost of goods sold.

 

4. Income Taxes

The Company accounts for income taxes under SFAS No. 109, “Accounting for Income Taxes.” The Company did not record a tax provision in the FY 2006 statement of operations as the Company did not generate taxable income.

At March 31, 2006, the Company had net operating loss carryforwards for income tax purposes of approximately $106,290,000. The Company also had available tax credit carryforwards of approximately $5,590,000 at March 31, 2006 to reduce future federal income taxes, if any. Federal and state net operating losses of approximately $7,689,000, $7,390,000 and $7,050,000 expired in fiscal 2006, 2005 and 2004, respectively. The net operating loss and tax credit carryforwards will continue to expire at various dates. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service and may be limited in the event of certain changes in the ownership interest of significant stockholders.

5. Stockholders’ Equity

 

  (a) Common Stock and Warrants

On March 1, 2006, Repligen engaged CEOcast, Inc. to render investor relations services. In exchange and as consideration for CEOcast Inc.’s investor relations services, Repligen issued 25,000 shares of common stock to CEOcast Inc. The Company recorded the value of these shares as selling, general and administrative expense in fiscal year 2006 in the accompanying statements of operations.

On March 1, 2004, pursuant to a licensing agreement, Repligen issued 17,986 shares of Repligen common stock to the University of North Carolina (“UNC”) and The Stanley Medical Research Institute (“Stanley”), in partial consideration for the assignment by UNC and Stanley to Repligen of a U.S. patent application claiming the use of secretin for treatment of certain behavioral disorders, including schizophrenia. The grant of the shares was recorded as research and development expense in 2004 in the accompanying statements of operations.

At March 31, 2006, the Company has reserved 2,842,859 shares of common stock for incentive and nonqualified stock option plans.

 

  (b) Stock Options

Shareholder Rights Plan

In March 2003, the Company adopted a Shareholder Rights Agreement (the “Rights Agreement”). Under the Rights Agreement, the Company distributed certain rights to acquire shares of the Company’s Series A junior participating preferred stock (the “Rights”) as a dividend for each share of common stock held of record as of March 17, 2003. Each share of common stock issued after the March 17, 2003 record date has an attached Right. Under certain conditions involving an acquisition by any person or group of 15% or more of the common stock, each Right permits the holder (other than the 15% holder) to purchase common stock having a value equal to twice the exercise price of the Right, upon payment of the exercise price of the Right. In addition, in the event of certain business combinations after an acquisition by a person or group of 15% or more of the common stock (20% in the case of a certain stockholder), each Right entitles the holder (other than the 15% holder) to receive, upon payment of the exercise price, common stock having a value equal to twice the exercise price of the Right. The Rights have no voting privileges and, unless and until they become exercisable, are attached to, and automatically trade with, the Company’s common stock. The Rights will terminate upon the earlier of the date of their redemption or March 2013.

 

6. Commitments and Contingencies

Lease Commitments

In 2001, the Company entered into a ten-year lease agreement for its corporate headquarters in Waltham, Massachusetts. In connection with this lease agreement, the Company issued a letter of credit in the amount of $200,000 to its landlord. The letter of credit is collateralized by a certificate of deposit held by the bank that issued the letter of credit. The certificate of deposit is classified as restricted cash in the accompanying balance sheet as of March 31, 2006 and 2005.

Licensing and Research Agreements

The Company licenses certain technologies that are, or may be, incorporated into its technology under several agreements and also has entered into several clinical research agreements which require the Company to fund certain research projects. Generally, the license agreements require the Company to pay annual maintenance fees and royalties on product sales once a product has been established using the technologies. The Company has recorded research and development expense associated with license agreements of $114,000, $55,000, and $298,000, for the years ended March 31, 2006, 2005 and 2004, respectively.

Supply Agreements

The Company has entered into an agreement with a manufacturer for certain components of its Protein A product. The Company has remaining purchase obligations of approximately $35,000 associated with this agreement for the year ended March 31, 2007. The Company relies on a sole manufacturer for its SecreFlo® product. This reliance exposes it to a number of risks, including reduced control over manufacturing capacity, delivery times, inadequate inventory levels which could lead to product shortage or charges for excess or obsolete inventory.

In February 2004, the Company terminated its Licensing Agreement with ChiRhoClin. On May 9, 2005, Repligen entered into a Settlement Agreement with ChiRhoClin, Inc., in full settlement of their arbitration proceedings described below. Repligen determined that it was not required to pay approximately $1,170,000 of unremitted and accrued royalties to ChiRhoClin. This was recorded as other income in the quarter ended June 30, 2005. In February 2004, the Company terminated its Licensing Agreement with ChiRhoClin. On May 9, 2005, Repligen entered into a Settlement Agreement with ChiRhoClin, Inc., in full settlement of their arbitration proceedings described below. Repligen determined that it was not required to pay approximately $1,170,000 of unremitted and accrued royalties to ChiRhoClin. This was recorded as other income in the quarter ended June 30, 2005. Under the terms of the Agreement, Repligen also received a payment of $750,000 and will be entitled to continue to market SecreFlo®, for the next several years under a royalty structure more favorable to Repligen than under the Licensing Agreement. ChiRhoClin is obligated to deliver a certain amount of SecreFlo®, to Repligen over the next few years. This payment of $750,000 was recorded as “Accrued Liabilities” at the time of settlement. The adoption of EITF 02-16 Accounting by a Customer (Including a Reseller) for Certain Consideration Received from a Vendor (EITF 02-16) has resulted in the Company reducing cost of goods sold as future inventory purchased from ChiRhoClin is sold. Other current liabilities as of March 31, 2006 includes $536,350 related to ChiRhoClin settlement which will be relieved as a reduction to cost of good sold as future inventory purchased from ChiRhoClin is sold.

 

9. Employee Benefit Plan

The Repligen Corporation 401(k) Savings and Retirement Plan (the “401(k) Plan”) is a qualified defined contribution plan in accordance with Section 401(k) of the Internal Revenue Code. All employees over the age of 21 who have completed four months of service are eligible to make pre-tax contributions up to a specified percentage of their compensation. Under the 401(k) Plan, the Company may, but is not obligated to match a portion of the employees’ contributions up to a defined maximum. The match is calculated on a calendar year basis. The Company matched $27,278, $34,245, and $34,395, for the fiscal years ended March 31, 2006, 2005, and 2004 respectively. Forfeitures of previous participants funded this contribution and as a result had no impact on the Company’s operations.

 

10. Related Party Transaction

Repligen paid Drs. Schimmel and Rich, the Co-Chairmen of the Board of Directors, $49,200 and $43,200, respectively, during each of the fiscal years ended March 31, 2006, 2005 and 2004 pursuant to consulting agreements, which have similar terms. These agreements are automatically extended for successive one-year terms unless terminated by either party to the agreement at least 90 days prior to the next anniversary date. Dr. Schimmel’s agreement continues until September 30, 2006 and Dr. Rich’s agreement continues until October 31, 2006. Drs. Schimmel and Rich have advised Repligen that they have no present intention of

terminating their agreements. Drs. Schimmel and Rich receive no separate cash compensation for attendance at meetings or otherwise as directors.

 

11. Legal Proceedings

Bristol-Myers Squibb Company

In January 2006, Repligen Corporation and The University of Michigan jointly filed a complaint against Bristol in the United States District Court for the Eastern District of Texas for infringement of U.S. Patent No. 6,685,941 (“the ‘941 patent”) for the commercial sale of Orencia®. The ‘941 patent, entitled “Methods of Treating Autoimmune Disease via CTLA4-Ig,” covers methods of using CTLA4-Ig to treat rheumatoid arthritis, as well as other therapeutic methods. Repligen has exclusive rights to this patent from its owners, the University of Michigan and the U.S. Navy. In February, Bristol answered the complaint and counterclaimed seeking a declaratory judgment that the ‘941 patent is invalid and unenforceable and that Bristol does not infringe the patent. The outcome of this case is undeterminable at this time.

ImClone Systems, Inc.

In May 2004, Repligen Corporation and The Massachusetts Institute of Technology (“MIT”) filed an action for patent infringement in the United States District Court for the District of Massachusetts against ImClone Systems, Inc. (“Imclone”) for infringement of U.S. Patent No. 4,663,281 (“the ‘281 patent”) based on Imclone’s manufacture and sale of the cancer drug Erbitux®. The technology claimed by the ‘281 patent, which was invented by researchers at MIT, covers certain genetic elements (DNA enhancers) that increase protein production in a mammalian cell. Repligen is the exclusive licensee of the ‘281 patent from MIT. Damon Biotech, a predecessor of Repligen, developed the cell line which is used to manufacture Erbitux® in 1990 for the National Cancer Institute and incorporated the DNA enhancer technology which is the basis of the ‘281 patent. Repligen seeks relief, including compensation in the form of royalties for the material Imclone manufactured prior to the expiration of the ‘281 patent in May of 2004.

In February 2006, the Court heard oral arguments on summary judgment motions brought by plaintiffs Repligen and MIT and defendant Imclone on the issue of exhaustion of patent rights. The Court may: 1) rule in plaintiffs’ favor, dispose of Imclone’s patent exhaustion defense and set the case for trial; 2) deny both parties’ motions and set the case for trial; or 3) rule in Imclone’s favor and enter judgment against plaintiffs in the case, subject to appeal.

Repligen and MIT have also filed an application for patent term extension for the ‘281 patent, which if granted will extend the term of the patent to May 2009. The outcome of this case is undeterminable at this time.

ChiRhoClin, Inc.

In February 2004, Repligen terminated the September 1999 Licensing Agreement with ChiRhoClin, its supplier of SecreFlo®, based on ChiRhoClin’s alleged failure to meet its obligations under the Licensing Agreement.

On April 9, 2004, Repligen filed an arbitration demand against ChiRhoClin with the American Arbitration Association in New York seeking to recover payments made to ChiRhoClin and additional damages. In this arbitration demand, Repligen alleged that ChiRhoClin breached several of its obligations under the September 1999 Licensing Agreement including failure to use best efforts to obtain various FDA approvals and to manufacture and supply SecreFlo®, in a timely manner. In June 2004, ChiRhoClin filed a counterclaim alleging that Repligen had wrongfully terminated the Licensing Agreement.

On May 9, 2005, Repligen entered into a Settlement Agreement (the “Agreement”) with ChiRhoClin, Inc., in full settlement of the arbitration proceedings described above. Under the terms of the Agreement, Repligen

Table of Contents

received a payment of $750,000 and will be entitled to continue to market SecreFlo®, for the next several years under a royalty structure more favorable to Repligen than under the Licensing Agreement. ChiRhoClin is obligated to deliver a certain amount of SecreFlo®, to Repligen over the next few years. This payment of $750,000 was recorded as “Accrued Liabilities” as of June 30, 2005. The adoption of EITF 02-16 has resulted in the reduction of cost of goods sold as future inventory purchased from ChiRhoClin is sold. After depletion of all supplies of SecreFlo® provided by ChiRhoClin, including those to be delivered under the Agreement, Repligen will cease marketing and selling a secretin product supplied by ChiRhoClin. ChiRhoClin will pay Repligen a per unit royalty on all sales by ChiRhoClin of its secretin products subject to certain time and/or volume limits. Repligen is not required to pay approximately $1,170,000 of unremitted royalties to ChiRhoClin related to sales from February 2004 to March 2005. This amount which was accrued at March 31, 2005 was recorded as other income in the quarter ended June 30, 2005. Repligen has received security for ChiRhoClin’s performance under the Agreement.

From time to time, the Company may be subject to other legal proceedings and claims in the ordinary course of business. Repligen is not currently aware of any such proceedings or claims that it believes will have, individually or in the aggregate, a material adverse effect on the business, financial condition or results of operations.
