Organization and Nature of Business | 1. Organization and Nature of Business Repligen Corporation (the “Company”, “Repligen”, “our” or “we”) (NASDAQ: RGEN) is a global life sciences company that develops and commercializes highly innovative bioprocessing technologies and systems that increase efficiencies and flexibility in the process of manufacturing biological drugs. The Company’s franchises include filtration, chromatography, process analytics and proteins. The Company’s bioprocessing products are sold to major life sciences companies, biopharmaceutical development companies and contract manufacturing organizations worldwide. A majority of the Company’s 19 manufacturing sites are located in the United States (including California, Massachusetts, New Hampshire, New Jersey and New York). Outside the United States, there are manufacturing sites in Estonia, France, Germany, Ireland, the Netherlands, Sweden, and Taiwan. The Company is subject to a number of risks typically associated with companies in the biotechnology industry. These risks principally include the Company’s dependence on key customers, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with the United States (“U.S.”) Food and Drug Association 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.
