DexCom, Inc. price, consensus and EPS surprise
Wrapping up
DexCom delivered a solid second-quarter update, marked by double-digit top-line growth and a confident raise in full-year guidance, as it executes on broadening access to CGM and scaling its innovation engine.
Strong new customer additions on the back of expanded reimbursement for the fast-growing type 2 non-insulin population drove U.S. sales. Meanwhile, momentum in international markets was driven by key coverage wins such as Ontario’s Drug Benefit program in Canada and continued traction for the cost-effective DexCom ONE+ platform across Europe.
On the product front, DexCom is leveraging both hardware and software to to keep its business afloat amid rising competition. The upcoming 15-day G7 sensor, cleared by the FDA, is set to be launched in the second half of 2025, while development on the next-gen G8 platform is underway, promising smaller, multi-analyte-ready wearables. Meanwhile, over 400,000 downloads of DexCom’s new Stelo biosensor app highlight consumer adoption beyond diabetes, with integrations like Oura Ring enabling a more personalized health ecosystem.
DXCM’s new AI-powered Smart Food Logging feature for G7 and Stelo enables users to snap meal photos, automatically log details, and assess glycemic impact — enhancing personalization, improving dietary awareness and simplifying diabetes management.
Margins faced near-term pressure, with gross margin at 60.1% due to expedited logistics costs as inventory was being rebuilt. Still, DexCom reaffirmed its 2025 gross margin guidance of 62% and raised full-year revenue guidance.
Management also flagged a succession plan — current CEO Kevin Sayer will step down in early 2026, passing the reins to long-time executive Jake Leach. The transition comes as DexCom doubles down on expanding CGM access, scaling globally and integrating AI-driven features across its platforms.
While CMS’s proposed competitive bidding program for Medicare CGM could emerge as a future headwind, DexCom believes the 2027 start timeline and its differentiated clinical data give it a strong footing. The company’s CGM sensors are now covered by the three largest pharmacy benefit managers. With access opened to approximately 6 million new lives, DexCom sees this as the first step toward a 25 million-person opportunity. With ample cash reserves and a steadily growing base of prescribers and end-users, the company appears well-positioned to maintain leadership in a rapidly expanding CGM market.
