Its flagship product is the t:slim X2 insulin pump, a subcutaneous device that delivers insulin and can work with other diabetes management devices through interoperable technology. A key feature is Basal-IQ, which uses continuous glucose monitoring data to predict low blood sugar and pause insulin delivery to prevent hypoglycemia. The company generates revenue from selling pumps and accessories like infusion sets and cartridges, as well as software updates and subscriptions for advanced management features, creating recurring income. Tandem differentiates itself with interoperable hardware and software that aim to simplify diabetes care and integrate with other devices, not just sell a single pump. Its goal is to improve diabetes management and quality of life by providing user-friendly, connected insulin delivery and management solutions for patients aged six and older.

Tandem Diabetes expands Mobi insulin pump to Android, aiming for $1.1B in 2026 sales

Tandem Diabetes Care has expanded its Tandem Mobi automated insulin delivery system to compatible Android smartphones in the US, following FDA clearance in November 2025 and a limited release in December. The Android rollout broadens accessibility for Mobi users and strengthens the company's position in smartphone-based diabetes management. The expansion supports Tandem's investment thesis by widening accessibility and reinforcing ecosystem retention, though near-term pressures remain from flat renewal expectations and ongoing losses. Combined with October 2025's integration of t:slim X2 with Abbott's FreeStyle Libre 3 Plus CGM, the move demonstrates a broader connectivity strategy. Tandem's narrative projects $1.2 billion revenue and $14.4 million earnings by 2028, requiring 7.5% yearly revenue growth. The company's 2026 sales guidance stands at approximately $1.065 billion to $1.085 billion.

Tandem hits record 58% margin, plans pharmacy shift and tubeless 'Toby' pump launch

Tandem Diabetes Care reported a record fourth-quarter gross margin of 58%, driven by pricing, rising Mobi volume and early pharmacy channel adoption. The company is transitioning US sales to a pharmacy pay-as-you-go model, creating a near-term $70–$80 million revenue headwind in 2026 but offering materially higher long-term reimbursement—approximately double over four years and four times monthly versus durable medical equipment. Tandem is expanding direct international sales in Switzerland, Austria and the UK, with an expected average selling price uplift of at least 20%. The company plans to submit its tubeless Mobi cartridge, nicknamed "Toby", to the FDA in Q2 for commercial rollout in the second half of the year. The device will be compatible with existing Mobi pumps.
