Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
MDxHealth SA doesn’t file a US annual report (10-K), so we haven’t checked it.
A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.

Everything above is arithmetic on public filings. The deep dive reads the last ten years of annual reports, the proxy statements, and the earnings calls, then argues the case the way Buffett, Klarman, and Hohn would, and checks every claim against the source.
