BFLYButterfly Network, Inc.
Is the business good?
The checks split: margins widening, but 3 of 9 health tests passed.
Weak, deteriorating fundamentals. Nine pass/fail tests of year-over-year health from the filings.
Operating margin has widened over the past few years, the business is getting more profitable per dollar of sales.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
