Most smaller companies that are in there growth phase will payout little or nothing in the form of dividends so their payout ratios are usually near zero. Older larger companies tend to have less internal growth potential and tend to pay out a larger portion of their earnings in the form of dividends.
One unique situation are the REITs and BDCs which by law payout 90% or more of their earnings. These companies generally have little or no internal growth potential and are generally just finance companies. They borrow money at low interests rates and then loan it out at a higher interest rate. The spread between the two rates is their profit margin and as long as they payout 90% or more of their earnings they don't have to pay any taxes.
