Four straight years of revenue decline, a wrecked balance sheet, and a not-cheap 3.2x sales — the turnaround isn't priced in your favor.

Revenue $86.5M · FY2025

HBIO is a shrinking business wearing a growth-company multiple. Revenue has fallen every year since FY2021 — $119M → $113M → $112M → $94.1M → $86.5M — with FY2025 down another 8.1%, and there's no evidence in the numbers of a bottom. Management's answer is a strategic pivot (NAMs, organoid/3D biology, SoHo telemetry, MeshMEA/Incub8) plus a portfolio and headcount rationalization, but that's a narrative about a future business, not the one in the filing. At $6.15 the stock trades at 3.2x trailing sales for a franchise that is contracting, which is the wrong direction for that multiple to be justified.

The headline -$56.7M net loss overstates the operational damage — $47.95M of it is a non-cash goodwill impairment (55.4% of revenue), and ex-impairment the operating line is roughly breakeven. Operating cash flow was actually positive at $6.73M (up 367%), gross margin held at a healthy 57.7%, recurring revenue is 55% of the mix, and the December 2025 refinancing pushed out the current debt portion (from prior year to $0). Those facts are why this is a sell and not an avoid: the company isn't in an imminent liquidity spiral.
