Documented cause
Americanas SA was formed in 2021 through the merger of B2W Digital (Americanas.com, Submarino, Shoptime) with Lojas Americanas, creating one of Brazil's largest retail conglomerates backed by 3G Capital partners Jorge Paulo Lemann, Marcel Telles, and Carlos Alberto Sicupira. On January 12, 2023, newly appointed CEO Sergio Rial disclosed R$20B in accounting inconsistencies related to undisclosed supply chain finance obligations — a practice known in Brazil as risco sacado — and resigned after only 10 days in the role. The stock collapsed by over 70% that day. One week later, Americanas SA filed for bankruptcy protection with R$43B in total debts, the largest in Brazilian corporate history. Brazilian federal police arrested former CEO Miguel Gutierrez and other executives in August 2023 in connection with fraud charges.
Lesson
“Supply chain finance can be weaponised to hide liabilities for years without triggering accounting alarms. When a company is owned by legendary investors, auditors and boards ask fewer questions — which is exactly when the most questions should be asked.”
