Capstone Partners Advises Sani-Tech West, Inc. on its Sale to 3i Group

Capstone Partners, a leading middle market investment banking firm, advised Sani-Tech West, Inc. (STW), a manufacturer and distributor of medical components, on its sale to CTS Bioprocessing, a portfolio company of 3i Group.

Founded in 1991, STW is a leading U.S.-based manufacturer, distributor and integrator of single-use, high-purity bioprocessing systems and components used in the manufacture of biotechnology and pharmaceutical drugs. Operating in Southern California, STW designs, develops, and manufactures single-use solutions including bottle assemblies, aseptic transfer systems, caps, flasks, tubes and clamps. The Company’s customers include many of the leading domestic and international biotech and pharmaceutical manufacturers.

My team and I were impressed with Capstone’s team from the very beginning. They took the time to understand the company, understood the real value, and then they truly delivered. With their guidance, we prepared a package that made us ready to enter the market at auction and ultimately, we found the perfect strategic buyer. The team guided 3i into a position to take us off the street. Capstone made the process virtually seamless and I could not be happier with the results.

Eric Willams, Head of Capstone’s Healthcare Investment Banking Team, said “It was a real pleasure for our team to work with the management of Sani-Tech West, one of the leading companies in the manufacture of single use, disposable components used in bioprocessing. We were able to find the ideal buyer in 3i’s bioprocessing platform whose complementary products create a world class entrant in the space. Richard Shor and the management team at Sani-Tech West built a highly innovative business that received strong investor interest. Together with 3i, STW has an opportunity to grow to several times its current size.”
