Down 12% This Year, Nubank Plans a ‘100b Pivot’ And Investors Are Taking

Quick Read

• Nu Holdings (NU) reported Q4 2025 net income of $895M (+62% YoY), full-year revenue of $15.77B, and achieved an efficiency ratio of 19.9%—the first time below 20%—while serving 131M customers and receiving conditional OCC approval for a U.S. national bank charter. SoFi Technologies (SOFI) has declined 35.45% year-to-date, suggesting broader sector de-rating pressures on high-growth digital banks.

• Nu’s fully digital model and AI credit-decisioning system (nuFormer) deliver world-class operational efficiency far below the U.S. banking industry average of 11x P/E, but analyst price target cuts from Bank of America and UBS reflect concerns that valuation premiums in high-growth fintech are contracting.

Nu Holdings (NYSE:NU) is down 12.73% year-to-date as of March 23, 2026, and trading near $14.70, yet the business underneath looks nothing like a company in trouble. Nubank just printed $895 million in net income for Q4 2025, received conditional OCC approval for a U.S. national bank charter on January 29, 2026, and now serves 131 million customers across Latin America. That gap between price and business performance is exactly what Reddit investors are debating.

The Efficiency Number That Changes the Conversation

Nubank’s Q4 2025 efficiency ratio came in at 19.9%, the first time it has fallen below 20%. That metric measures how much revenue is consumed by operating costs. Most major U.S. banks operate with efficiency ratios well above Nubank’s, and Nubank’s ratio has collapsed from 78% in Q4 2021 to 20% recently. It’s a fully digital model that eliminates branch costs entirely, and its AI credit-decisioning model, nuFormer, delivers a 3x improvement in accuracy over traditional underwriting machine learning.

Full-year 2025 revenue reached $16.3 billion with record net income of $2.9 billion, up from $1.97 billion in FY 2024, while adjusted return on equity hit 33% for Q4.
