• The Tandem Mobi insulin pump is the world's smallest durable automated insulin delivery (AID) system.
• We believe our offering of remote software updates for insulin pumps is a competitive advantage that allows us to bring our customers clinical and lifestyle enhancements within their warranty cycle without having to purchase a new pump.
• We are pursuing additional regulatory and pre-commercial activities, such as securing in-country registrations and reimbursement, before launching Tandem Mobi outside the United States.
• We are preparing to serve t:slim X2 customers for their cartridges and infusion sets beginning in the fourth quarter of 2025 through the pharmacy channel.
• We expect our expenses will continue to increase as we pursue our objectives and make investments in our business.

Industry Context

The diabetes management industry is highly competitive and subject to rapid technological change. Tandem Diabetes Care operates within this dynamic environment, offering advanced automated insulin delivery systems like the t:slim X2 and the new Tandem Mobi. The market is influenced by the introduction of new devices and treatments from competitors such as Beta Bionics, Insulet, Medtronic, Sequel, and Ypsomed. A significant trend impacting the insulin therapy market is the ongoing adoption and expanded use of GLP-1 class drugs for diabetes and obesity, which has likely had a negative impact on the insulin therapy market. Regulatory changes, such as the proposed competitive bidding process and monthly rental payment models by CMS for medical equipment including insulin pumps and CGMs, could significantly alter reimbursement landscapes. The company's strategy to expand into the pharmacy channel for product distribution reflects an adaptation to evolving healthcare reimbursement models.

Comparison to Industry Standards

• Tandem Mobi, at approximately half the size of the t:slim X2, is positioned as the world's smallest durable automated insulin delivery (AID) system, offering a competitive advantage in discretion and flexibility compared to larger pump systems from competitors like Medtronic and Insulet (Omnipod).
• The company's Control-IQ+ technology, and its predecessor Control-IQ, have demonstrated improved clinical outcomes across demographics, supported by multiple studies including four publications in the New England Journal of Medicine, suggesting strong clinical efficacy comparable to or exceeding industry benchmarks.
• The remote software update capability for the t:slim X2 pump is a competitive differentiator, allowing for continuous enhancements without new pump purchases, a feature not universally offered by all competitors.
• The company's expansion into the pharmacy channel for Tandem Mobi and planned expansion for t:slim X2 supplies aims to broaden access and compete with models like Insulet's Omnipod, which is already widely available through pharmacy benefits.
• The impact of GLP-1 drugs on the insulin therapy market is a broader industry trend affecting all insulin pump manufacturers, potentially reducing the addressable market for intensive insulin therapy devices.

Corporate Governance

Legal Proceedings

• Entered into a Settlement, Mutual Release and Cross-License Agreement with F. Hoffmann-La Roche AG and its subsidiaries on May 21, 2025, resolving all actual or potential patent disputes, including actions before the Unified Patent Court in France and Germany. This resulted in a $20.0 million litigation and settlement expense.
• The company is involved in various other legal proceedings, regulatory matters, and disputes arising from normal business activities, including intellectual property, data privacy, employment, regulatory, product liability, and contractual matters.
• As of June 30, 2025, the company believes it is not currently a party to any legal proceedings for which a material loss was considered probable or reasonably estimable, but acknowledges that legal proceedings can have an adverse impact due to defense and settlement costs, and diversion of management time.

Stakeholder Impact

• Shareholders: Experienced significant dilution risk from potential future capital raises and a substantial decrease in total stockholders' equity. The widening net loss and increased cash burn could negatively impact stock price volatility.
• Employees: Affected by restructuring activities in the first quarter of 2025, leading to lower employee-related expenses in R&D. The company faces challenges in retaining and motivating key personnel amidst intense industry competition.
• Customers: Benefit from new product approvals like the Tandem Mobi CE Mark and planned expansion into the pharmacy channel for supplies, potentially improving access and choice. However, changes in reimbursement policies (e.g., CMS proposals) could impact affordability and access.
• Suppliers: The company's dependence on a limited number of third-party suppliers creates risks for supply continuity and cost management, potentially impacting the company's ability to meet customer demand.
• Creditors: The company's significant indebtedness from convertible senior notes requires substantial cash for debt service, and any inability to generate sufficient cash flow could affect its ability to repay obligations.

Next Steps

• Pursue additional regulatory and pre-commercial activities for Tandem Mobi outside the United States, including securing in-country registrations and reimbursement.
• Prepare to serve t:slim X2 customers for their cartridges and infusion sets through the pharmacy channel beginning in the fourth quarter of 2025.
• Continue enhancing features and capabilities of t:slim X2 and Tandem Mobi insulin pump platforms, including adding a tubeless infusion site option for Tandem Mobi users.
• Advance development efforts for Sigi, the ergonomic and rechargeable patch pump, extended wear infusion technology, and algorithm advancement towards fully closed-loop technology.
• Expand commercial resources for the growing installed customer base.
• Make investments in the development, improvement, and acquisition of manufacturing, testing, and packaging equipment to support business growth and increase capacity.
• Potentially enter into additional financings (equity or debt) to fund future capital requirements.

Key Dates

Recommendation

While Tandem Diabetes Care demonstrated revenue growth and improved gross margins, the significant widening of net losses due to substantial one-time expenses (litigation settlement, IPR&D, restructuring, and impairment charges) and increased cash burn from operations present considerable financial headwinds. The company's strategic product advancements, such as the Tandem Mobi CE Mark and pharmacy channel expansion, offer long-term potential. However, the immediate financial performance, coupled with ongoing risks related to competition, reimbursement changes, and the need for future capital, suggests a 'hold' recommendation. Investors should monitor the company's ability to integrate acquisitions, manage operating expenses, and achieve profitability as these one-time costs subside and new products gain market traction, before considering a more aggressive stance.
