Material Changes vs. Prior Period
- Revenue Growth: Sales increased 5.5% year-over-year, driven by higher pump shipments (29,000+ units vs. ~28,000 in Q1 2025) and improved average selling prices. U.S. sales grew 6.8%, while international sales grew 3.1%.
- Profitability Improvement: The operating loss narrowed significantly from $120.9 million to $17.4 million. This improvement was primarily due to the absence of a $75.2 million one-time acquired in-process research and development (IPR&D) charge and $11.2 million in restructuring/impairment charges incurred in Q1 2025.
- Gross Margin Expansion: Gross margin improved to 55% from 51%, attributed to favorable product mix, foreign currency impacts, and lower material costs.
- Debt Financing: In February 2026, the company issued $300 million in 0.00% Convertible Senior Notes due 2032, netting $291.2 million in proceeds. This increased total long-term convertible debt on the balance sheet by approximately $292 million compared to the prior year-end.
- Reimbursement Strategy: The company is transitioning to a "pay-as-you-go" pharmacy channel model in the U.S., which initially reduces upfront pump revenue but aims to increase recurring supply revenue over the customer lifecycle.
Guidance, Outlook, and Risks
- Strategic Outlook: Management expects the pharmacy channel strategy to eventually offset the decrease in upfront pump sales with higher supply sales. The company is expanding direct sales operations in select European countries.
- Product Pipeline: Future developments include a next-generation Mobi patch pump leveraging Sigi Patch Pump technology, extended-wear infusion sets, and dual glucose-ketone sensor integration.
- Liquidity: As of March 31, 2026, the company held $570.3 million in cash and short-term investments, deemed sufficient to fund operations for at least the next 12 months.
- Key Risks:
- Reimbursement Uncertainty: Risks associated with the transition to pharmacy benefits and potential changes in CMS competitive bidding processes.
- Debt Service: Significant indebtedness ($616 million principal) requires cash for interest payments (on 2029 notes) and potential conversion settlements.
- Regulatory & Supply Chain: Dependence on third-party suppliers (including for CGM integration with Dexcom and Abbott) and potential regulatory delays or recalls.
- Profitability: The company has an accumulated deficit of $1.27 billion and cannot assure sustained profitability.
Investor Verification Checklist

- Assess the sustainability of gross margin improvements amidst potential supply chain inflation and material cost fluctuations.
- Review the status of direct sales expansion in Europe and its impact on distributor relationships.
- Track the progress of the next-generation Mobi patch pump and regulatory approvals for new features.
