Banco Mercantil undervalued growth bank.
Banco Mercantil (BMEB4) is a bank focused on serving retirees (50+). It won the 2024 INSS auction, giving it a competitive advantage in distributing retirement benefits. Its physical branches allow it to offer high-margin products like 'Meu Mais' health assistance, driving strong revenue growth. The bank trades at a low multiple (4x earnings, 40% ROE, 40% growth) but faces a temporary increase in provisions due to technical issues with private payroll loans (consignado privado). Management is conservative and provisioning more than peers. The bank has a small market share outside its core regions, indicating large expansion potential. The main risk is low liquidity; once liquidity improves, the market will better recognize the bank's value.
