Growing CGM Market Size
The global continuous glucose monitoring market was valued at $10.9 billion in 2024 and is projected to grow to $47.1 billion by 2034. This represents a compound annual growth rate in the mid-to-high teens.
Multiple independent analyses confirm robust market growth projections. The CGM market is expected to reach nearly $29 billion by 2030, according to industry forecasts.
Several factors drive this expansion. Increasing diabetes prevalence, technological improvements, expanding insurance coverage, physician adoption, and growing patient awareness all contribute.
As market leader, Dexcom is positioned to capture a disproportionate share of this growth. However, maintaining share requires continued innovation and competitive vigilance.
Weaknesses: Internal Challenges and Vulnerabilities
Regulatory and Quality Control Issues
In March 2025, the FDA issued a warning letter to Dexcom following inspections of its San Diego and Mesa facilities. The letter cited significant quality system regulation violations.
Most seriously, the FDA stated that G6 and G7 CGM systems were “adulterated” because Dexcom made unauthorized changes to a critical sensor component. The company changed the sensor coating material without securing proper FDA approval.
Internal testing revealed that sensors with the unauthorized coating performed worse on every accuracy metric Dexcom measured. This raised serious concerns about patient safety and data reliability.
While Dexcom stated it does not anticipate material impact on manufacturing capacity or 2025 revenue, the reputational damage is significant. Trust in accuracy is fundamental to CGM adoption.
The company has responded with corrective actions. However, these issues demonstrate potential gaps in quality management systems that must be addressed systematically.
Class Action Lawsuits and Legal Exposure
Multiple class action lawsuits have been filed against Dexcom related to the FDA warning letter and alleged sensor failures. By late 2025, multiple law firms reported active case filings in state and federal courts.
Lawsuits claim that G6 and G7 systems failed to provide accurate readings or critical alerts, leading to severe injuries and death. Plaintiffs allege the company failed to warn about risks and produced a defective product.
Dexcom faces a securities fraud class action with a deadline that passed in December 2025. Allegations center on misleading investors about product quality and regulatory compliance.
Legal costs and potential settlements could be substantial. More importantly, these lawsuits generate negative publicity that could impact physician recommendations and patient confidence.
Leadership Transition and Organizational Changes
In July 2025, Dexcom announced CEO succession plans. Long-time CEO Kevin Sayer took a leave of medical absence in September 2024.
Jake Leach, previously Executive Vice President, was promoted to President and COO in February 2025, then became interim CEO.
While Leach brings deep company experience, leadership transitions create uncertainty. Vision, strategy execution, and stakeholder relationships all face potential disruption.
The company also implemented workforce reductions associated with organizational realignment during 2025. These restructuring efforts suggest internal challenges in optimizing operations at scale.
Maintaining innovation velocity and market execution during this transition period requires careful management. Any stumbles could provide openings for competitors.
Manufacturing and Supply Chain Complexity
Dexcom plans to cease G6 CGM production after July 1, 2026. This transition from G6 to G7 represents a major manufacturing shift.
While G7 offers improved user experience, the transition creates operational complexity. The company must manage inventory levels, customer migration, insurance approvals, and global rollout timing.
Any production issues with G7 could leave gaps if G6 manufacturing winds down prematurely. Balancing this transition requires precise forecasting and flexible manufacturing capacity.
The FDA warning letter also highlighted manufacturing process deficiencies related to change control and validation procedures. Addressing these systemic issues while scaling production adds complexity.
Building new manufacturing facilities and expanding capacity requires significant capital investment. Execution risks include construction delays, equipment validation, regulatory approvals, and workforce training.
Gross Margin Pressure
Dexcom’s GAAP gross profit margin was 60.5% in Q3 2025, up from 59.7% in Q3 2024. However, non-GAAP gross margin declined to 61.3% from 63.0% year-over-year.
Full-year 2025 non-GAAP gross margin guidance of ~61% represents compression from historical levels. Several factors contribute to this pressure.
The Stelo over-the-counter product operates at lower margins than prescription CGM. As Stelo grows as a percentage of revenue, blended margins face headwinds.
Competitive pricing pressure from Abbott and others limits pricing power. International expansion into lower-price markets also creates margin mix effects.
Manufacturing scale improvements and cost reductions can offset some margin pressure. However, maintaining healthy margins while expanding market access presents an ongoing challenge.
Threats: External Challenges and Competitive Dynamics
Intense Competition from Abbott Laboratories
Abbott’s FreeStyle Libre franchise represents Dexcom’s most formidable competitor. Abbott’s Diabetes Care revenue grew nearly 20% on an organic basis in 2024.
In Q2 2025, Abbott’s CGM sales exceeded $1.90 billion, growing 19.6% organically. Momentum was particularly strong in the United States.
Abbott dominates the flash glucose monitoring segment. The FreeStyle Libre 3 offers competitive accuracy, smaller form factor, and aggressive pricing.
In October 2025, Walmart became the first U.S. retailer to sell Abbott’s Lingo continuous glucose monitor in physical stores. This retail availability across 3,500+ Walmart locations dramatically improves consumer access.
While Dexcom held an estimated 74% share of the U.S. CGM market in 2024, Abbott’s aggressive expansion threatens this position. The over-the-counter market will intensify competitive dynamics.
Emerging Competitors and New Entrants
Beyond Abbott, several companies are developing competitive CGM systems. Medtronic’s Guardian 4 system offers real-time monitoring with integration into insulin pump systems.
Eversense 365, an implantable CGM with 12-month sensor life, represents a disruptive alternative to disposable systems. If widely adopted, long-duration implantable sensors could reshape market dynamics.
Smaller companies like Senseonics and international players continue developing alternatives. Innovation from unexpected sources could disrupt established market positions.
Technology giants like Apple reportedly have long-term interest in non-invasive glucose monitoring. While technical challenges remain significant, breakthrough innovations from well-funded technology companies could transform the market overnight.
The proliferation of competitors and alternatives creates pricing pressure and fragments market share. Dexcom must continuously innovate to maintain technological leadership and justify premium positioning.
Reimbursement and Healthcare Policy Risks
While Medicare and private insurance coverage has expanded, reimbursement remains uncertain. Policy changes could dramatically impact market access and economics.
Medicare coverage determinations occur periodically. Restrictive criteria changes or reimbursement rate reductions would limit the addressable market or compress margins.
Private payers continually evaluate cost-effectiveness. Some insurers designate preferred CGM brands based on cost. Anthem’s designation of Dexcom as preferred represents a win, but such decisions can reverse.
International reimbursement environments vary widely. Many countries have limited CGM access or strict eligibility criteria. Expanding global coverage requires navigating diverse healthcare systems and demonstrating cost-effectiveness.
Healthcare reform efforts could reshape diabetes device coverage. Value-based care models might favor lower-cost alternatives unless Dexcom demonstrates superior outcomes justifying premium pricing.

Technology Disruption and Non-Invasive Monitoring
The holy grail of glucose monitoring is accurate, non-invasive measurement. Multiple companies and research teams are pursuing optical, electromagnetic, and other approaches.
While no non-invasive technology has achieved commercial viability for diabetes management, breakthroughs could render subcutaneous sensors obsolete. The risk seems distant but not impossible.
Smartphone-based monitoring applications and algorithms continue improving. While they cannot replace hardware sensors currently, software innovations could reduce reliance on specialized devices.
Artificial intelligence and machine learning increasingly enable predictive glucose modeling. If algorithms can reliably forecast glucose levels hours ahead, the value proposition of continuous monitoring shifts.
Dexcom must stay ahead of technological curves. Being disrupted by fundamentally new approaches would be catastrophic. Significant R&D investment in next-generation sensing modalities is essential.
Macroeconomic Headwinds and Healthcare Spending
Economic slowdowns impact healthcare spending, particularly for devices not perceived as immediately life-saving. While insulin-dependent diabetes patients require CGM, the vast type 2 non-insulin market is more discretionary.
Insurance coverage decisions reflect healthcare cost pressures. Economic downturns often trigger stricter coverage criteria and greater cost-consciousness among payers and patients.
The Stelo over-the-counter product faces direct consumer spending decisions. In difficult economic times, $99-$149 monthly costs may seem prohibitive for people managing type 2 diabetes without insulin.
Foreign exchange fluctuations impact international revenue and margins. A strong U.S. dollar reduces translated revenue from overseas markets. In Q3 2025, organic revenue growth excluded $11.4 million of foreign exchange impact.
Supply chain disruptions, inflation in raw materials, and labor cost increases all pressure margins. While Dexcom’s financial position provides cushion, sustained cost inflation without pricing power could compress profitability.
Strategic Initiatives for 2026 and Beyond
Manufacturing Excellence and Quality Systems
Addressing the FDA warning letter deficiencies represents the most immediate strategic priority. Dexcom must demonstrate robust quality management systems and manufacturing controls.
This requires investing in quality infrastructure, personnel training, process documentation, and validation protocols. Regaining full FDA confidence is essential for maintaining market credibility.
Simultaneously, the company must scale production to meet growing demand. Building new facilities and expanding capacity in San Diego, Mesa, and potentially new locations requires careful execution.
The transition from G6 to G7 manufacturing must be managed smoothly. Any supply disruptions would damage customer relationships and provide competitive openings.
International Market Development
With international revenue representing only 30% of total revenue, geographic expansion offers substantial growth potential. Europe, Asia-Pacific, Latin America, and other regions are underpenetrated.
Securing favorable reimbursement in key markets like Germany, France, United Kingdom, Japan, and Australia will drive volume. Each country requires tailored clinical evidence, health economic data, and regulatory strategies.
The Dexcom ONE+ value-tier product addresses price-sensitive markets. Expanding this portfolio internationally without cannibalizing premium G7 sales requires careful positioning.
Building local commercial infrastructure, including sales teams, customer support, and distribution networks, enables sustainable international growth. Partnerships with local distributors can accelerate market entry.
Type 2 Diabetes Non-Insulin Market Penetration
The type 2 non-insulin market represents Dexcom’s largest single growth opportunity. Converting even a small percentage of this population would drive substantial revenue.
Generating clinical evidence demonstrating benefits for non-insulin users strengthens reimbursement cases. Studies showing A1C improvements, weight loss support, and medication optimization justify coverage.
Physician education programs familiarize primary care doctors and endocrinologists with CGM benefits beyond insulin management. Many providers remain unaware of use cases for non-insulin patients.
Direct-to-consumer marketing for Stelo builds awareness and drives over-the-counter purchases. Digital marketing, retail presence, and patient testimonials all contribute to adoption.
Expanding insurance coverage for type 2 non-insulin users through pharmacy benefit managers and commercial payers will dramatically accelerate penetration. Each coverage decision unlocks millions of potential users.
