Nubank reported net profit of $894.8 million for the fourth quarter of 2025, a 50% increase from $552.6 million in the same quarter a year earlier, as the Brazilian digital bank continued to translate its exceptional growth in the customer base into accelerating bottom-line performance. Total revenue for the fourth quarter rose 45% year-on-year to $4.86 billion, the company said in its earnings release, with the combination of higher lending income and expanding fee revenue driving the top-line momentum.
The combined customer base across Nubank's operations in Brazil, Mexico, and Colombia reached 131 million, reinforcing the group's position as one of the largest financial institutions in Latin America by customer count and among the largest digital banks anywhere in the world. The scale of the franchise, built entirely through digital channels without the branch infrastructure that traditional banking incumbents have relied on for decades, represented a competitive position that established lenders in the region have found extremely difficult to replicate at comparable cost.
LOAN PORTFOLIO GROWS 40% TO $32.7 BILLION
Nubank's total loan portfolio expanded 40% year-on-year to $32.7 billion, reflecting strong demand for the company's credit products across all three of its operating geographies. The expansion of the loan book was the principal driver of revenue growth, as interest income from lending activities accounted for a substantial portion of the 45% increase in total quarterly revenue. The growth rate of the portfolio indicated that Nubank continued to deepen its penetration of the credit markets in Brazil, Mexico, and Colombia, particularly among the large segment of consumers who had previously been underserved or entirely excluded from the formal banking system.
The 50% year-on-year increase in net profit, achieved simultaneously with a 40% expansion of the loan book, demonstrated that Nubank's credit quality management was keeping pace with its volume growth. The company has been refining its proprietary credit scoring and risk management models over several years, applying machine learning techniques to large datasets of transaction and behavioural information to improve underwriting precision. The profitability trajectory in the quarter suggested those models were generating adequate risk-adjusted returns even as the loan book scaled rapidly.
US REGULATORY APPROVAL OPENS NEW MARKET
Nubank received its first regulatory approval from United States authorities in January 2026, a development that the company's earnings release highlighted as opening the door to an eventual market entry into the United States. The approval represented a strategically significant milestone for a company that had until that point operated exclusively in Latin America, and it was seen by analysts as a signal of management's ambition to apply the group's digital-first model in one of the world's largest, most competitive, and most profitable consumer financial services markets.
The fourth-quarter result presented Nubank as a company operating with strong operational momentum across all of its key metrics. With net profit up 50% to $894.8 million, total revenue rising 45% to $4.86 billion, 131 million customers across three countries, a loan portfolio of $32.7 billion growing at 40%, and freshly obtained regulatory approval to pursue expansion into the United States, the Brazilian fintech closed the 2025 financial year having established itself as a genuinely global-scale financial services group rather than simply a Latin American digital banking challenger.
