Tandem Diabetes Care Inc (TNDM) Q3 2026 Earnings Call Highlights: Record Revenue
Tandem Diabetes Care (TNDM) reported Q3 2026 earnings, with CFO Lee Vospler forecasting mid-to-high single-digit 2027 revenue growth, below consensus. CEO John Sheridan expects Mobi Tubeless FDA approval in Q4 2026 and a pivotal trial for a fully closed-loop system to begin in Q4 2026. The company saw 26% international growth, driven by new product launches and strong execution. Tandem also announced a CEO transition, with Jeanette Bankes set to take over.
