Repligen offers a diverse portfolio of products used to grow cell cultures, measure bioprocess metrics during manufacturing, and purify products downstream. Investors don't have to be technically competent to appreciate the role that the company plays in the high-growth biopharma sector. After all, if biotech companies cannot safely and efficiently manufacture drug products, then they won't be in business very long.
The bioprocessing leader is relatively small compared with the better-known players in the space, such as General Electric's GE Healthcare subsidiary, Samsung BioLogics, Thermo Fisher Scientific, and Sartorius. But Repligen has done a great job making the most of its high-margin niche and geographic proximity to Boston, a world-leading biotech hub.
Investors should have little doubt that the business can maintain its momentum. In 2018, the Food and Drug Administration approved a record 11 monoclonal antibodies (the main category of biologic drug), while more than 400 more were in development across the industry's pipeline. Combine that with gene therapies, other genetic medicines, and cellular medicines that receive billions of dollars in investment across the biopharma sector, and Repligen has "long-term investment" written all over it.
