Expert Insights

From a fundamental perspective, DexCom’s G7 rollout represents a critical moat-widening initiative for the company, as its 15-day wear time addresses a key patient pain point relative to competing 10-day CGM products, even as peers ramp up their own next-generation offerings. Our channel checks indicate G7 now makes up 62% of DexCom’s U.S. prescription CGM volume as of Q1, up from 41% in Q4 2025, with adoption expected to rise to 75% by the end of 2026. While pricing mix headwinds from pharmacy channel expansion and emerging market entry are dragging average selling prices (ASPs) down ~2.7% sequentially, the 17% sequential volume lift from expanded access is more than offsetting ASP pressure, putting the company on track to hit consensus revenue targets. On the profitability front, we forecast gross margins will expand 85 basis points (bps) YoY in Q1, driven by lower freight costs and higher-margin G7 product mix, though operating expenses will rise 18% YoY due to ongoing capacity buildout for G7 and Stelo, plus R&D investment in the company’s upcoming 30-day CGM prototype. This dynamic will limit operating margin expansion to just 25 bps YoY, in line with consensus forecasts. While DexCom’s Zacks Rank 2 rating signals solid long-term upside, its 0.00% Earnings ESP means short-term investors should not price in a high probability of an earnings beat. For traders seeking medical product stocks with stronger near-term earnings beat potential, we highlight three peers with favorable ESP and Zacks Rank combinations: Microbot Medical (MBOT, Earnings ESP +8.70%, Zacks Rank 2), which beat earnings in two of the past four quarters for an average surprise of 7.53%; Henry Schein (HSIC, Earnings ESP +0.28%, Zacks Rank 3), which beat estimates in three of the past four quarters for an average surprise of 2.14%; and IDEXX Laboratories (IDXX, Earnings ESP +0.77%, Zacks Rank 3), which has beaten estimates in four consecutive quarters for an average surprise of 6.11%. For long-term investors, DexCom’s current valuation of 72x 2026 consensus EPS, a 157% premium to the broader medtech sector average of 28x, is justified by its projected 16% annual revenue CAGR through 2029, driven by G7 adoption, Stelo’s OTC total addressable market (TAM) expansion, and international reimbursement gains. Any post-earnings dip on a neutral or modest earnings miss would present an attractive entry point for investors with a 3+ year investment horizon, as the company’s core CGM market position remains structurally strong amid rising global diabetes prevalence.
