Tandem Diabetes Care Completes Acquisition of Insulin Patch Pump Developer, AMF Medical

SAN DIEGO – January 23, 2023 — Tandem Diabetes Care, Inc. (NASDAQ: TNDM), a global insulin delivery and diabetes technology company, today announced the completion of its previously announced acquisition of AMF Medical SA, the privately held Swiss developer of the Sigi™ Patch Pump. The Sigi Patch Pump, designed to be an ergonomic, rechargeable patch pump that reduces the burden of managing diabetes through its use of pre-filled insulin cartridges, is under development and not commercially available.

“AMF Medical's compelling technology aligns well with our strategic vision to include a patch pump in Tandem’s portfolio of differentiated offerings,” said John Sheridan, Tandem Diabetes Care President and Chief Executive Officer. “In addition to this innovative technology, the talented AMF team joining our Tandem family shares our commitment to simplify diabetes management and brings decades of experience from the diabetes device, life sciences, and watch-making industries.”

“AMF Medical was founded to develop a patch pump that is not only simple to use for people with diabetes, but also optimized for scale manufacturing,” said Peter Ryser, AMF Medical’s Chairman and Co-Founder. “We are thrilled that our work will be carried forward by a mission-driven company like Tandem,” added Antoine Barraud, Co-Founder and Co-CEO, noting that “Tandem not only shares our deep-rooted dedication to diabetes technology, but has created an incredibly user-focused culture that is very well aligned with our company values.”

Baker & McKenzie LLP and Bass, Berry & Sims PLC served as legal advisors to Tandem Diabetes Care. SVB Securities LLC served as exclusive financial advisor and Homburger AG served as legal advisor to AMF Medical.
