AI Summary

6.0
Neutral

TMDX remains a compelling growth story, but investors should now demand proof that its logistics and international investments can convert 20%+ revenue growth into recovering margins and free cash flow before adding exposure, as rising leverage and a heavier cost base raise the downside if utilization lags.
