6.5
Positive

BLLN now looks more like a multi-vertical diagnostics platform than a one-product growth story, with 84% YoY revenue growth and raised guidance supporting the upside case, but the investment hinges on proving reimbursed adoption and margin leverage fast enough to justify its rich low-200s P/E.
