How we determine this
WashIndex classifies ownership structure from data it can verify: franchise status from SBA loan records, acquisition signatures from customer-review text, and footprint from the per-location index. A specific corporate or private-equity owner is named only where it is publicly established — we do not infer or guess parent companies. Where ownership isn't disclosed, the page says so.
