Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Q3 2025 sales increased 2% year-over-year, driven by improved average selling prices and higher supply volumes, partially offset by a slight decrease in pump shipments (approx. 30,000 pumps shipped in Q3 2025 vs. nearly 21,000 in Q3 2024; note: text indicates "more than 20,000" vs "nearly 21,000" for Q3, but YTD shipments were 88,000 vs prior year trends). International sales grew due to favorable foreign exchange rates.
• Margin Expansion: Gross margin improved to 54% in Q3 2025 from 51% in Q3 2024, attributed to better pricing and reduced non-manufacturing costs.
• Significant One-Time Expenses (YTD): The YTD operating loss widened significantly due to:
  • Acquired IPR&D: A $75.2 million charge related to the revised AMF Medical purchase agreement.
  • Litigation & Settlement: $20.0 million expense related to the Roche Cross-License Agreement.
  • Restructuring & Impairment: Approximately $10.9 million in combined facility impairment and restructuring costs.
• Debt Repayment: The company fully settled the remaining $40.8 million principal of its 2025 Convertible Senior Notes in Q2 2025. As of Q3 2025, only the 2029 Notes remain outstanding.
• Tax Benefit: The company recognized an income tax benefit of $4.0 million in Q3 2025 (vs. expense in 2024) due to the "One Big Beautiful Bill Act" (OBBBA) passed in July 2025, which allowed for immediate expensing of domestic R&D expenditures.

Guidance, Outlook, and Risks

• Strategic Shifts: The company is implementing a multi-channel managed care strategy in the U.S., expanding reimbursement through pharmacy benefits for both pumps and supplies, moving beyond the traditional medical benefit model.
• Product Pipeline: Focus remains on the t:slim X2 and Tandem Mobi. The company received CE Mark approval for Tandem Mobi in May 2025 and is pursuing international launches. Future pipeline includes a next-generation patch pump (Sigi technology) and extended-wear infusion sets.
• Liquidity: Management believes cash, cash equivalents, and short-term investments ($319.1 million) are sufficient to fund operations for at least the next 12 months.
• Key Risks:
  • Reimbursement: Potential changes in CMS competitive bidding processes and payment structures (e.g., monthly rental basis) could impact revenue timing and rates.
  • Competition: Intense competition from Insulet, Medtronic, and others; potential obsolescence from new therapies (e.g., GLP-1 drugs).
  • Regulatory & Safety: Risks of product recalls (noted past recalls in 2024 and 2025) and cybersecurity threats to connected devices.
  • Supply Chain: Dependence on limited third-party suppliers and exposure to tariffs/trade barriers.

Investor Verification Checklist

• Verify the sustainability of the 54% gross margin given the shift to pharmacy benefit reimbursement models.
• Confirm the timeline and regulatory status for the international launch of the Tandem Mobi pump.
• Monitor the impact of the "One Big Beautiful Bill Act" (OBBBA) on future tax provisions and R&D capitalization.
• Assess the progress of the AMF Medical integration and the commercial viability of the Sigi Patch Pump technology.
• Review the company's ability to maintain liquidity given the significant YTD operating loss and ongoing R&D investments.
