Summary
Summary of the 8-K filed February 12, 2026. Cited figures are marked; the original filing is the authoritative source.
DexCom reported fourth-quarter and full-year 2025 results on February 12, 2026, capping a strong year of growth.
Q4 revenue rose 13% year-over-year to $1.260 billiona (12% organic), with U.S. revenue up 11% and international up 18%. GAAP operating income reached $323.0 million (25.6% margin), up 860 basis points, while non-GAAP operating margin was 26.3%. For the full year, revenue grew 16% to $4.662 billion (15% organic), and GAAP operating income of $911.8 million (19.6% margin) was up 470 basis points.
GAAP diluted EPS for 2025 was $2.09b, versus $1.42 in 2024. Profitability improvement is the central story. Operating leverage is visible in both GAAP and non-GAAP figures, helped by a lower share of operating expenses relative to revenue and strong gross margin (GAAP gross margin of 62.9% in Q4 versus 58.9% a year earlier).
Full-year 2025 other income of $176.6 millionc, which includes a $78.1 million gain from equity investments, flattered net income, so investors should separate that non-operating contribution from core earnings. The company ended the year with $2.00 billion in cash and marketable securities and an undrawn revolving credit facility, giving it flexibility to expand manufacturing capacity and pursue new markets. For 2026, DexCom reiterated revenue guidance of $5.16 to $5.25 billion (about 11% to 13% growth), non-GAAP gross margin of roughly 63% to 64%, and non-GAAP operating margin of roughly 22% to 23%.
It also introduced Adjusted EBITDA margin guidance of roughly 30%d to 31%. The filing notes that organic growth and margin guidance were not reconciled to GAAP because certain items are difficult to predict. The 8-K furnishes the press release under Item 2.02 and is not deemed filed under the Exchange Act.

Under Item 2.02, the press release is furnished as Exhibit 99.1 and is not deemed filed for purposes of Section 18 of the Exchange Act.
