The company completed its Initial Public Offering (IPO) in January 2025, raising approximately $190.4 million in net proceeds, alongside a concurrent private placement of $15.6 million. The company is classified as an Emerging Growth Company and a Smaller Reporting Company.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 63% year-over-year in Q3 and 52% year-over-year for the nine-month period. This growth was driven by a 68% increase in New Patient Starts (NPS) to 5,334 in Q3 2025 (vs. 3,180 in Q3 2024) and higher recurring sales of single-use products.
• Channel Mix Shift: There is a strategic shift toward the Pharmacy Benefit Plan (PBP) channel. PBP sales represented 23% of net sales in Q3 2025, up from 13% in Q3 2024. While PBP sales initially generate negative gross margin due to lower upfront device revenue, they are expected to yield higher lifetime value through recurring single-use product sales.
• Expense Increases: Operating expenses rose significantly due to headcount expansion in sales, marketing, and R&D to support commercialization and new product development (patch pump, bihormonal system). Stock-based compensation expense increased to $4.5 million in Q3 2025 from $2.0 million in Q3 2024.
• Liquidity Position: Following the January 2025 IPO, the company's cash, cash equivalents, and investments grew to $274.0 million, providing a runway through the first half of 2028.

Guidance, Outlook, and Risks

• Outlook: Management expects expenses to continue increasing as the company scales commercial operations and invests in R&D for a patch pump and a bihormonal system (insulin + glucagon). The company anticipates continued growth in new patient starts and a favorable long-term economic impact from the PBP channel mix.
• Regulatory Status: The iLet is subject to a mandatory FDA post-market surveillance order (Section 522), requiring a one-year prospective study of 1,875 users. Enrollment began in April 2025, with a final report due to the FDA by June 2027.
• Key Risks:
  • Single Product Dependence: All revenue is derived from the iLet and related single-use products.
  • Supply Chain: Reliance on single-source suppliers for critical components (infusion sets, pump motors, cartridge connectors).
  • Reimbursement: Success depends on maintaining coverage and reimbursement rates across DME and PBP channels.
  • Profitability: The company has incurred significant losses since inception and expects to continue doing so for the foreseeable future.

Investor Verification Checklist

• Verify the runway calculation based on the $274 million cash balance against the projected burn rate of ~$42 million per quarter in operating cash outflows.
• Monitor the gross margin trajectory as the PBP channel mix increases, specifically watching for the point where cumulative PBP margins turn positive.
• Review the post-market surveillance study progress and any FDA communications regarding the Section 522 order.
• Assess the single-source supplier risk for infusion sets (Unomedical), motors (Maxon), and connectors (PMC) and any contingency plans disclosed.
• Track New Patient Starts (NPS) trends and the percentage of patients transitioning from Multiple Daily Injections (MDI) to the iLet.
