The thesis, from the filings

WINDTREE THERAPEUTICS INC /DE/ earns about -303% on invested capital, but has diluted owners by 211% over 5 years — worth asking whether the growth reaches owners. The cash-flow models don't apply cleanly here — the ledger says why below. Whether it’s worth owning at today’s price is the last question — and yours to answer, below.
