The thesis, from the filings

BillionToOne, Inc. earns about 2% on equity, but has diluted owners by 117% over 3 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.

Management signal · capital allocation
+117% shares · 3y
