indicates the clear winner per row. Ties and missing data are not highlighted.
How winners are chosen
Lower is better for investment, liquid capital, franchise fee, royalty and ad-fund rates, SBA charge-off rate, and owner turnover.
Higher is better for disclosed revenue and owner earnings, verdict score, total units, net unit growth, and franchisee contacts. For the letter grade, A ranks highest.
A row is highlighted only when one brand clearly leads. Ties are never highlighted, and missing data never counts as a win. Some rows (earnings-metric type, loan counts, contract terms) are informational and have no winner.
