Shares surged nearly 10% to $15.29 after Nu Holdings, Latin America's largest digital bank, posted record second-quarter results that blew past Wall Street expectations on virtually every metric. The consensus had called for $0.20 per share on estimated revenue of $5.39 billion . Nu delivered far more: revenue of $5.88 billion, up 39% year over year, and net income of $1.06 billion — a 49% increase — with return on equity at 33% . The question now is whether this quarter marks a permanent shift in earning power or the peak of a favorable credit cycle.
• A Billion-Dollar Quarter Silences the Skeptics — For Now
For years, Nu's investment case rested on a promise: acquire customers cheaply, serve them at a fraction of traditional bank costs, then deepen the relationship. Q2 looks like the quarter where that model became "a visibly scaled earnings machine."
Gross profit rose 43% year over year to $2.44 billion , growing faster than revenue — a sign the company is extracting more from each dollar earned. Risk-adjusted net interest margin expanded to 12.4%, up sharply from 9.9% a year ago .
• 139 Million Customers, but Mexico Is the Growth Story to Watch
Nu added roughly 4 million customers, reaching 139 million globally . Mexico hit 15.8 million (16 million as of July), and Colombia surpassed 5 million . Critically, monthly activity rates climbed to 83.5%, with Brazil topping 86% for the first time — meaning customers are not just signing up but actively using the platform. Mexico recently received full banking authorization, which unlocks deposit-taking and lending products that could dramatically boost revenue per customer there.
• Credit Quality Is the Risk Investors Cannot Ignore
Asset quality was mixed: the early-warning delinquency ratio (loans 15–90 days past due) improved to 4.8%, but loans more than 90 days overdue rose to 6.9% — up from 6.5% a year earlier. Credit card balances jumped 35% to $26 billion, while unsecured lending surged 45% to $10.3 billion . Rapid loan growth in higher-risk segments can inflate profits today while seeding losses tomorrow.
• The Valuation Gap Is Narrowing Fast
One fair-value estimate pegs the stock at roughly $16, close to today's post-rally price , while the analyst consensus target sits at $17.59, with a wide range from $10 to $22 . At around 17 times forward earnings, Nu trades at a steep premium to traditional Latin American banks. Sustaining that premium demands more billion-dollar quarters — not just one.
