StoneCoNarrow moat

StoneCo sells Brazilian small businesses the machinery of getting paid. It started with the card terminal — the little box on the counter — and built outward: acquiring the transaction, advancing the merchant the money early, holding the deposit, and increasingly lending against the revenue it can already see. The customer is the corner shop, the hairdresser, the restaurant: five million or so businesses that Brazil's big banks served badly for decades, which is the entire reason StoneCo exists.

The money arrives in three related streams. Payments is the volume — roughly R$560.9 billion of transactions processed in 2025 — earning a take rate on each. Financial income is the prepayment business: merchants get their card receivables early and StoneCo keeps the discount, which makes a meaningful share of profit a function of Brazilian interest rates. And banking is the newer, stickier stream: about 3.7 million active banking clients holding roughly R$11 billion of deposits¹, with a credit book rebuilt to about R$2.8 billion at the end of 2025 after an earlier attempt failed badly.

StoneCo has also been subtracting. The Linx software business, bought in 2021 for reasons that never fully justified the price, was sold to TOTVS for an enterprise value around R$3.05 billion² — leaving a company deliberately narrower than the one that went public: payments, banking and credit for merchants, and nothing else.

The returns are real and the market does not believe them. Return on equity above 26%, and a share price at a mid-single-digit multiple of earnings³ — a valuation that prices Brazil's country risk, Pix's assault on payment economics, and the memory of the 2021 credit disaster, all at once.

The pages that follow take those two facts separately. The Moat examines the distribution engine, the financial operating system, payments scale and the credit-underwriting data — the case for why this is a real franchise rather than a cheap stock. The Future Bets follow what management is actually doing about the doubt: rebuilding credit carefully, unifying merchants into one account, absorbing an interest-rate headwind it cannot control, and returning about a quarter of the company's market value to shareholders in a single year. Its four revenue lines are taken in turn in The Revenue Lines.
