PLUGPlug Power Inc.
Is the business good?
The checks split: nothing decisive, though margins compressing.
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating margin has narrowed over the past few years, profitability per dollar of sales is eroding.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
