Tandem Diabetes Care Investment Narrative Recap

To own Tandem Diabetes Care, you need to believe in the long term adoption of its automated insulin delivery ecosystem across both type 1 and type 2 diabetes. The August 2025 t:slim X2 device correction and related securities investigation add headline and legal risk, but do not fundamentally alter the near term product pipeline catalyst or the broader shift toward connected pump therapy, unless they eventually impair physician or patient confidence in the brand.
