Nu Holdings: Why Profit Quality Matters More Than Customer Count

Nu Holdings' real strength lies in revenue per customer, return on equity, and managing credit risk—not just growing its user base.

Nu Holdings has eclipsed $1 billion in quarterly profits, a milestone no one expected to arrive this fast given its digital banking roots. But the real story isn’t the sheer number of customers—it’s in the details of profit quality. The rise in Average Revenue Per Active Customer from $13 to $17 shows Nu isn’t just signing up users; it’s extracting more value from each one. Meanwhile, a 33% return on equity is exceptional, especially for a company scaling fast in Latin America’s tricky credit environment. Yet, the uptick in non-performing loans to nearly 7% signals caution. If this trend accelerates, it could quickly erode profitability. For South African investors, Nu’s results offer a useful contrast when looking at local banks like Capitec or Standard Bank, who grapple with similar credit risks but lack Nu’s rapid revenue growth per customer. The USD/ZAR may also react if Nu’s LatAm success encourages broader investor interest in emerging market fintech. Still, rising credit risk is the wild card here. this is just our opinion and not financial advice

How I would invest

Watch Nu carefully—its profit quality story is compelling, but rising loan defaults add risk. Avoid jumping in; wait for clearer signs that credit quality has stabilized before buying.

How strongly I feel

6/10

Nu Holdings, a digital bank serving 139 million customers across Brazil, Mexico, and Colombia, achieved its first quarterly profit above $1 billion in Q2 2026. Rather than focusing on customer count, investors should monitor three key metrics: Average Revenue Per Active Customer (ARPAC) which reached $17 (up from $13 year-over-year), Return on Equity at 33% annualized, and the 90+ day non-performing loan ratio at 6.9%. These metrics indicate whether the company can increase customer value, generate efficient returns on capital, and maintain manageable credit risk as its lending portfolio grows.
