See accompanying notes to financial statements. 5 REPLIGEN CORPORATION NOTES TO FINANCIAL STATEMENTS (Unaudited) 1. Basis of Presentation The financial statements included herein have been prepared by Repligen Corporation (the "Company" or "Repligen"), pursuant to the rules and regulations of the Securities and Exchange Commission for quarterly reports on Form 10-Q and do not include all of the information and footnote disclosures required by generally accepted accounting principles. These financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Form 10-K for the year ended March 31, 2001. In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting of only normal, recurring adjustments, necessary to present fairly, the consolidated financial position, results of operations and cash flows of the Company. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the entire year. The preparation of financial statements in conformity with 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. 2. Revenue Recognition The Company generates product revenues from the sale of its Protein A products to customers in the pharmaceutical and process chromatography industries. The Company recognizes revenue related to product sales upon shipment of the product to the customer. Research and development revenue derived from collaborative arrangements is recognized as earned under cost plus fixed-fee contracts, or on a straight-line basis over development contracts, which approximates when work is performed and costs are incurred. Research and development expenses in the accompanying statements of operations include funded and unfunded expenses. In addition, under certain contracts, the Company recognizes revenue from research and development milestones when they are received as long as they are deemed to be substantiated. Licensing and royalties from the Company's licensed technologies are recognized as earned. The Company applies Staff Accounting Bulletin (SAB) No. 101, Revenue Recognition. SAB 101 requires companies to recognize certain upfront nonrefundable fees over the life of the related alliance when such fees are received in conjunction with alliances that have multiple elements. The adoption of SAB No. 101 did not have a significant impact on the Company's financial position on results of operations. 3. Net Loss Per Share The Company applies Statement of Financial Accounting Standards (SFAS) No. 128, Earnings per Share. Basic and diluted net loss per share represents net loss divided by the weighted average 6 number of common shares outstanding during the period. The dilutive effect of the potential common shares consisting of outstanding stock options and warrants is determined using the treasury stock method. Diluted weighted average shares outstanding for the three months ended June 30, 2001 and 2000 exclude the potential common shares issuable upon the exercise of warrants and stock options because to do so would be antidilutive for the periods presented. At June 30, 2001, there were outstanding options to purchase 1,643,341 shares of the Company's common stock at a weighted average exercise price of $2.65 per share and warrants to purchase 424,846 shares of the Company's common stock at a weighted average exercise price of $5.26 per share. At June 30, 2000, there were outstanding options to purchase 1,367,041 shares of the Company's common stock at a weighted average exercise price of $2.33 per share and warrants to purchase 954,782 shares of the Company's common stock at a weighted average exercise price of $3.91 per share. 4. Cash, Cash Equivalents and Marketable Securities The Company applies SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. At June 30, 2001, the Company's cash equivalents and marketable securities are classified as held-to-maturity, as the Company has the positive intent and ability to hold these securities to maturity. The Company considers highly liquid investments purchased with original maturities at the date of acquisition of 90 days or less to be cash equivalents. Marketable securities are accounted for at amortized cost, which approximates fair value. Cash, cash equivalents and marketable securities consist of the following at June 30, 2001 and March 31, 2001: June 30, March 31, 2001 2001 ----------- ----------- Cash and cash equivalents Cash $ 494,814 $ 222,766 Commercial paper and corporate bonds -- 489,719 Money market accounts 11,594,055 15,451,140 ----------- ----------- Total cash and cash equivalents $12,088,869 $16,163,625 =========== =========== Short-term marketable securities Corporate and other debt securities $13,382,135 $ 7,773,427 =========== =========== Long-term marketable securities Corporate and other debt securities $ 2,630,448 $ 5,992,478 =========== =========== 5. Inventories Inventories are stated at the lower of cost (first in, first out) or market and consist of the following at June 30, 2001 and March 31, 2001. June 30, March 31, 2001 2001 -------- -------- Raw materials and work-in-process $681,720 $459,288 Finished goods 229,792 175,435 -------- -------- Total $911,512 $634,723 ======== ======== Work in process and finished goods inventories consist of material, labor, outside processing costs and manufacturing overhead. 7 6. Comprehensive Income The Company applies SFAS No. 130 Reporting Comprehensive Income. SFAS No. 130 establishes standards for reporting and display of comprehensive income and its components in financial statements. Comprehensive income includes all non-owner changes in equity during a period. The Company's comprehensive net loss is the same as its reported net loss for all periods presented. 7. Disclosures about Segments of an Enterprise and Significant Customers 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. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision making group, in order to allocate resources and assess performance. To date, the Company has viewed its operations and manages its business as principally 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. The following table represents the Company's revenue by geographic area: Three Months Ended June 30, 2001 2000 ---- ---- US 58% 59% Europe 40% 40% Other 2% 1% ---- ---- Total 100% 100% During the three months ended June 30, 2001, there was one customer who accounted for approximately 70% of the Company's revenues. During the three months ended June 30, 2000, there were two customers who accounted for approximately 24% and 36% of the Company's revenues. Two customers accounted for 60% and 14%, respectively, of the Company's accounts receivable at June 30, 2001. Three customers accounted for 53%, 26% and 10%, respectively, of the Company's accounts receivable at March 31, 2001. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview We are developing innovative therapeutic products for debilitating pediatric diseases including autism, leukemia, metabolic and immune system diseases based on naturally occurring peptides and proteins. Our lead therapeutic products are secretin for autism, CTLA4-Ig for stem cell transplantation and uridine for mitochondrial disease. Our product candidates have the potential to produce clinical benefits not attainable with any existing drug, in diseases for which there are few alternatives. 8 Autism is a developmental disorder characterized by poor communicative and social skills, repetitive and restricted behaviors and in some patients, gastrointestinal problems and irregular sleep patterns. Secretin is a hormone produced in the small intestine which regulates the function of the pancreas as part of the process of digestion. A form of secretin derived from pigs is approved by the United States Food and Drug Administration ("FDA") for use in diagnosing problems with pancreatic function. Recent anecdotal reports indicate that secretin may have beneficial effects in autism, including improvements in sleep, digestive function, communicative and social behavior. Following media reports of the potential benefits of secretin, more than 2,000 autistic children have been treated with the pig-derived hormone. We have recently completed an FDA-approved, Phase 2 clinical trial on a human, synthetic form of secretin in order to evaluate its potential benefits. Results from the trial indicated that the parents of secretin-treated children rated their child's symptoms to be improved compared to children who received a placebo, a result that was statistically significant. We have also identified two biological markers that defined a group of patients. A statistically significant treatment effect of secretin was demonstrated in the 64 patients, or 51% of the total patient population, with normal levels of both biological markers. In this subgroup, there was a statistically significant effect of secretin by four endpoints including improvement in social function as determined with the Autism Diagnostic Observation Schedule, overall symptom improvements as determined by the Clinical Global Impression Scale ("CGI") by both a professional and independently a parent and an increase in receptive language as determined by the MacArthur Communicative Development Inventory. In February 2000, we were issued a broad U.S. patent covering the use of secretin in the treatment of autism. We are currently prosecuting additional patent applications in the United States, Europe and Japan. There are currently no drugs approved by the FDA for the treatment of autism. We are also developing a product named "CTLA4-Ig," which has been shown to suppress unwanted immune responses in animal models of organ transplants and autoimmune diseases, such as lupus or multiple sclerosis, in which the immune system mistakenly attacks the body. Our product candidate is a derivative of a natural protein whose role is to turn-off an immune response. In animal models of organ transplantation and autoimmune diseases, CTLA4-Ig has been shown to block the rejection of a transplanted organ or the effects of the autoimmune disease. Initial clinical testing of CTLA4-Ig has been carried out in patients receiving a bone marrow transplant, which is a potential cure for several diseases of the immune system, including leukemia, myeloma, lymphoma and sickle cell anemia. Despite the clinical success of bone marrow transplants, a significant number of patients experience a severe and potentially life-threatening complication known as Graft Versus Host Disease, in which the newly transplanted immune system attacks the host (i.e., the patient). In June 1999, results from a Phase 1 clinical trial reported that treatment of bone marrow from a family member with Repligen's CTLA4-Ig prevented Graft Versus Host Disease in eight of eleven transplant patients. In October 2000, the FDA approved the initiation of a Phase 2 clinical trial evaluating CTLA4-Ig in patients receiving stem cell transplant for leukemia or other malignancies. For more information on our intellectual property rights to CTLA4-Ig, please see "Legal Proceedings." In December 2000, the Company licensed from the University of California, San Diego (UCSD) rights to a U.S. patent application covering novel methods for the treatment of mitochondrial disease. Mitochondria are small bodies found in every cell, which produce energy for cellular processes. Mitochondrial diseases are characterized by impaired function of many tissues particularly skeletal muscles (weakness, poor motor skills), the nervous system (seizures, poor cognition) and dysfunction of the heart and kidney. Uridine is a naturally occurring substance required by all cells for the synthesis of RNA, DNA and other essential factors. Mitochondria are the only cellular (non-dietary) source of uridine and its synthesis is often impaired in patients with mitochondrial disease. In a Phase 1 study at UCSD, daily 9 administration of uridine or a derivative of uridine was well tolerated by the patients and produced symptom improvements in some patients. Repligen intends to extend these observations in a randomized, placebo-controlled clinical study in collaboration with UCSD and other clinical centers. For more information on our intellectual property rights to uridine and related compounds for the treatment of mitochondrial disease, please see "Legal Proceedings." We develop, manufacture and market products for the production of therapeutic antibodies. We currently market a line of products for the purification of antibodies based on a naturally occurring protein, Protein A, which can specifically bind to antibodies. Repligen owns composition of matter patents for recombinant Protein A in the United States and in Europe. In December 1998, we entered into a ten-year agreement to supply recombinant Protein A to Amersham Pharmacia Biotech, a leading supplier to the biopharmaceutical market. In October 1999, Repligen obtained a license from ChiRhoClin, Inc., a private company, to commercialize two diagnostic secretin products. These products are synthetic, injectable forms of the natural hormone which has been traditionally been used by gastroenterologists to assess the function of the pancreas. New Drug Applications (NDAs) have been filed for both products. The NDA for the synthetic porcine (pig-derived) product has been reviewed by the FDA which indicated that it could be approved for marketing in the United States upon satisfactory response by ChiRhoClin to a request for additional data concerning the product's manufacturing. Both synthetic products have been granted orphan drug status by the FDA. If the FDA approves either product, the license agreement obligates Repligen to pay ChiRhoClin future milestones in cash, Repligen common stock, and royalties. We cannot be certain that the FDA will approve either product. Results of Operations Revenues Total revenues for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $713,000 and $661,000 respectively, an increase of $52,000 or 8%. Product revenues for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $713,000 and $556,000, respectively, an increase of $157,000 or 28%. This increase is largely attributable to the timing of large-scale production orders of Protein A. Research and development revenues for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $0 and $30,000, respectively, a decrease of $30,000 or 100%. During fiscal 2001, a non-recurring licensing payment was received. Other revenues for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $0 and $75,000, respectively, a decrease of $75,000 or 100%. The revenue recognized in the first quarter of fiscal 2001 was a termination fee paid by a sublessee. Costs and Expenses Total costs and expenses for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $2,400,000 and $2,144,000, respectively, an increase of $256,000 or 12%. Research and development expenses for the three month period ended June 30, 2001 and June 30, 2000, were approximately $1,426,000 and $1,083,000, respectively, an increase of $343,000 or 32%. During the three months ended June 30, 2001, research and development expenses increased as a result of an increase in costs associated with our drug development programs, offset by a decrease in costs associated with patent application acquisition. 10 Selling, general and administrative expenses for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $617,000 and $731,000, respectively, a decrease of $114,000 or 16%. Increased spending on personnel and associated costs and increased legal costs during the three month period ended June 30, 2001 was offset by non-cash charges incurred for warrants issued to consultants during the three month period ended June 30, 2000. Cost of products sold for the three month periods ended June 30, 2001 and June 30, 2000, were approximately $356,000 and $330,000, respectively, an increase of $26,000 or 8%. Gross margin for products sold in the three month periods ended June 30, 2001 and 2000 were 50% and 41%, respectively. This increase in gross margin is due primarily to the product mix of product sales. Investment and Interest Income Investment income for the three month periods ended June 30, 2001 and June 30, 2000, was approximately $344,000 and $513,000, respectively, a decrease of $169,000 or 33%. This decrease during the three months ended June 30, 2001 is attributable to lower average funds available for investment and a lower interest rate environment. Liquidity and Capital Resources We have financed our operations primarily through private placements of common stock and revenues derived from product sales, collaborative research agreements, government grants, and payments received pursuant to licensing and royalty agreements. Total cash, cash equivalents and marketable securities at June 30, 2001 equaled $28,101,000, a decrease of $1,829,000 from $29,930,000 at March 31, 2001. Repligen's operating activities used cash of approximately $1,802,000 for the three month period ended June 30, 2001, consisting of a net loss from operations of approximately $1,344,000, an increase in inventory of $277,000 and prepaid expenses of $253,000 and a decrease in accounts payable and accrued expenses of $134,000. This use of cash was offset by non-cash charges of $83,000 for depreciation and amortization and decreases in interest receivable of $64,000 and other assets of $57,000. Our investing activities used cash of approximately $2,247,000 for the purchase of marketable securities. Our cash was reduced by capital expenditures of $29,000. Our financing activities provided cash of approximately $3,000 from the proceeds of a stock option exercise. Working capital increased to $26,530,000 at June 30, 2001 from $24,398,000 at March 31, 2001. While we anticipate that the cost of operations will increase as we continue to expand our investment in proprietary product development, we believe we have sufficient funding to satisfy our working capital and capital expenditure requirements for the next twenty-four months. Should we need to secure additional financing to meet our future liquidity requirements, there can be no assurances that we will be able to secure such financing, or that such financing, if available, will be on terms favorable to us. Cautionary Statement Regarding Forward-Looking Statements Statements in this Quarterly Report on Form 10-Q, as well as oral statements that may be made by the Company or by officers, directors or employees of the Company acting on the Company's behalf, that are not historical facts constitute "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934. Such forward-looking statements involve known 11 and unknown risks, uncertainties and other factors that could cause the actual results of the Company to be materially different from the historical results or from any results expressed or implied by such forward-looking statements. The Company's future operating results are subject to risks and uncertainties and are dependent upon many factors, including, without limitation, the Company's ability to (i) meet its working capital and future liquidity needs, (ii) successfully implement its strategic growth strategies, (iii) understand, anticipate and respond to rapidly changing technologies and market trends, (iv) develop, manufacture and deliver high quality, technologically advanced products on a timely basis to withstand competition from competitors which may have greater financial, information gathering and marketing resources than the Company, (v) obtain and protect licensing and intellectual property rights necessary for the Company's technology and product development on terms favorable to the Company, (vi) recruit and retain highly talented professionals in a competitive job market, (vii) realize future revenues, (viii) maintain a timeline for clinical development, (ix) obtain approval from the FDA for clinical trials or product marketing approvals (x) obtain successful results of pending or future clinical trials, (xi) continue to establish collaborative arrangements with third parties, and (xii) compete against the biotechnology and pharmaceutical industries. Further information on potential factors that could affect the Company's financial results are included in filings made by the Company from time to time with the Securities and Exchange Commission included in the section entitled "Risk Factors" contained in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2001 (File No. 0-14656). PART II. OTHER INFORMATION Item 2. LEGAL PROCEEDINGS 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 at the Superior Court of California, County of San Diego seeking to void the License Agreement entered into between Repligen and the University of California, San Diego ("UCSD") in December 2000 (the "UCSD License Agreement"). The Pro-Neuron Complaint, among other things, also requests the court order the Regents assign all rights licensed to Repligen pursuant to the UCSD License Agreement to Pro-Neuron pursuant to the Regent's agreement with Pro-Neuron. UCSD and Repligen believe that the Complaint is without merit and intend to vigorously defend their rights. If Pro-Neuron is successful in this action, Repligen's ability to commercialize uridine for mitochondrial disease may be limited. Repligen and the University of Michigan (the "University") believe that the University is entitled to rights to certain United States patents owned by Bristol-Myers Squibb Company ("BMS"), which patents cover claims for composition and methods of use for CTLA4. On August 31, 2000, Repligen and the University filed a complaint against BMS at the United States District Court for the District of Michigan in Detroit, Michigan seeking correction of inventorship on these patents. A correction of inventorship would result in the University being designated as a co-assignee on any corrected BMS patent. Repligen would then have rights to such technology pursuant to a 2000 License Agreement with the University, a 1995 Asset Acquisition Agreement with Genetics Institute and other related agreements. Repligen's failure to obtain shared ownership rights in the BMS patents may restrict Repligen's ability to commercialize CTLA4-Ig. Repligen and the University have also filed patents related to compositions of matter and methods of use of CTLA4-Ig. 12 Item 6.
