Question · Q4 2025
Michael Pollock from Wolfe Research posed a two-part question on gross margin: first, why the 2026 guide of 270 basis points expansion doesn't fully recover the 2025 one-timers (scrap, freight, recall) and account for 15-day product credit, and the current status of scrap and freight overhangs; second, the U.S. hardware mix of G6 vs. G7 10-day in 2025, and the projected mix including G7 15-day by end of 2026.
Answer
Jereme Sylvain, CFO of Dexcom, clarified that the one-timer impact was slightly less than estimated, with improvements playing through, but Q1 will see some spillover. He noted that the Ireland facility turning on in Q4 will shift fixed costs from OpEx to COGS, causing a gross margin decline in that quarter. Jake Leach, President and CEO of Dexcom, stated that the vast majority of the U.S. base is now on G7, with rapid declines in G6 users. He expects G6 to phase out towards mid-2026, with G7 15-day driving upgrades.
