DXCM: Expanding Reimbursement Will Drive Gains Despite Market Uncertainty

Key Takeaways

• Expanded reimbursement and international coverage unlock new patient segments, fueling sustained revenue growth while diversifying global revenue streams.
  
• Advances in product innovation, digital integration, and operational efficiencies drive higher margins, recurring revenues, and increased patient loyalty.
  
• DexCom faces rising pricing and competitive pressures, innovation risks, supply chain issues, and leadership transition challenges that threaten margins, growth, and market differentiation.

Catalysts

A medical device company, focuses on the design, development, and commercialization of continuous glucose monitoring (CGM) systems in the United States and internationally.

• The recent expansion of insurance reimbursement for type 2 non-insulin diabetes patients-now covering nearly 6 million lives across the three largest U.S. PBMs-opens a large, previously untapped segment of DexCom's addressable market, driving new patient growth and supporting robust multi-year revenue expansion.
  
• Growing global recognition of CGM efficacy, with recent clinical trial evidence and expanded coverage in international markets (e.g., France, Japan, and Ontario, Canada), positions DexCom to penetrate underpenetrated regions and diversify revenue streams, creating sustainable top-line growth.
  
• The rapid adoption of digital health, including remote monitoring, and increased integration of DexCom's CGMs with EHRs (e.g., Epic) and health wearables (like Oura), enhances differentiation, strengthens recurring device and software revenues, and increases patient retention, supporting both revenue growth and higher net margins.
  
• DexCom's continued software and hardware innovation-such as AI-powered features, generative AI in health tracking, and the upcoming launch of the 15-day G7 system-positions the company for premium pricing, improved user experience, and operating leverage, contributing to operating margin and earnings growth.
  
• Operating scale improvements (inventory normalization, manufacturing automation, and logistics efficiencies) are expected to reduce COGS and improve gross margins over the coming quarters, further boosting net income and free cash flow.

DexCom Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming DexCom's revenue will grow by 14.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 13.3% today to 21.9% in 3 years time.
• Analysts expect earnings to reach $1.4 billion (and earnings per share of $3.49) by about September 2028, up from $571.5 million today. However, there is some disagreement amongst the analysts with the more bearish ones expecting earnings as low as $1.1 billion.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 35.3x on those 2028 earnings, down from 53.8x today. This future PE is greater than the current PE for the US Medical Equipment industry at 29.7x.
• Analysts expect the number of shares outstanding to grow by 0.4% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.58%, as per the Simply Wall St company report.

DexCom Future Earnings Per Share Growth

Risks

• Proposed CMS competitive bidding for CGM devices may result in significant pricing pressure for DexCom's key Medicare fee-for-service segment (15% of revenue), potentially leading to squeezed net margins and reduced revenue growth from 2027 onward.
  
• Intensifying competition, particularly from major rivals integrating with insulin pumps and the emergence of dual
• or multi-analyte sensors, could erode DexCom's market share in its core type 1 diabetes patient base, pressuring both revenue and net margins.
  
• There is risk of plateauing in technological innovation as DexCom projects such as G8 and non-glucose analyte sensing remain in development, which, if delayed or superseded by alternative, possibly non-invasive, technologies, may threaten long-term product differentiation and future revenue streams.
  
• Ongoing supply chain challenges (evident from recent inventory shortages, heavy reliance on expedited shipping, and the need to rebuild finished goods inventory) expose DexCom to higher operational costs and potential lost sales, adversely impacting gross and operating margins.
  
• Transition in senior leadership (from long-term CEO Kevin Sayer to Jake Leach in 2026) introduces execution risk around the continuation and scale-up of DexCom's global growth and innovation strategies, with potential negative impacts on earnings if operational or strategic missteps occur during or after the transition.

Valuation

• The analysts have a consensus price target of $102.083 for DexCom based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $115.0, and the most bearish reporting a price target of just $83.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $6.5 billion, earnings will come to $1.4 billion, and it would be trading on a PE ratio of 35.3x, assuming you use a discount rate of 7.6%.
• Given the current share price of $78.4, the analyst price target of $102.08 is 23.2% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
