The thesis, from the filings

SolarWindow Technologies, Inc. earns about -111% on invested capital, but has diluted owners by 5% 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.
