DXCM does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.
13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

View Full Filing (SEC EDGAR)DexCom issued a press release on July 30, 2026, announcing its financial results for the quarter ended June 30, 2026, plus certain other information, and disclosed it under Item 2.02 of an 8-K. The press release is attached as Exhibit 99.1, but it is "furnished" rather than "filed" with the SEC, so it does not carry the same legal liability as a formal filing. The excerpt doesn't include the actual revenue or profit figures, so you'd need the press release itself for the numbers.
