Itaú: Brazil's biggest private bank still grows profit 18.9% a year

BankFormula: Peter Lynch · Price R$ 38.69 (Friday close)Peter Lynch asked for a score of 1.5. Itaú, Brazil's largest private bank, scores 2.9: profit up 18.9% a year for five years, a 7.5% yield and a P/E of 9.1.
The thesis
Big, mature banks are not supposed to grow 18.9% a year. Itaú did, for five years, with revenue up 17.4% a year and ROE never below 17.4% (21.5% in the last 12 months). Lynch's test adds growth to the dividend yield and divides by the P/E; 1.5 passes. With a 7.5% trailing yield and a P/E of 9.1, Itaú scores 2.9.
What the company does
Itaú Unibanco is Brazil's largest private bank: lending to people and companies, cards, investments and insurance, with operations in other Latin American countries. Management has said it does not want to sit on excess capital, and in December 2025 it paid a R$ 20 billion extraordinary dividend.
Why the formula picked it
Revenue and profit both grew more than 10% a year without the kind of jump the 40% cap screens out, with profit every year and ROE of 21.5%. Only four companies passed. Cemig actually ranked first, at 3.8, but it went to Bazin earlier in the order, so Itaú takes Lynch's slot.
Bear case
The 7.5% trailing yield leans on that one-off December payout, made before the 2026 dividend tax; the five-year average is 2.84%. Even on that lower yield the ratio would still clear 1.5, just with less room. At 1.96× book value, Itaú is the priciest of this week's four on that measure. And a bank's profit turns with the credit cycle: high rates show up in bad loans sooner or later.
What would break the story
Revenue or profit growth falling under 10% a year, ROE under 12%, or the Lynch ratio slipping under 1.5, which a lower yield or a higher P/E would both cause.
