NU has shown steady quarterly revenue growth from $3.25 billion in early 2025 to $5.52 billion in Q2 2026, with expanding gross profit margins and operating income ratios. The net income margin improved from around 13.4% in 2023 to over 19.2% in Q2 2026, signaling enhanced profitability. Operating expenses have increased moderately but are well controlled relative to revenue scale.

Revenue growth has been driven primarily by organic expansion in lending and payment volumes powered by increased customer base and higher engagement per user. Rising interest income from loan portfolios has been a key driver given increasing lending balances. Cost of revenue, while rising, has grown at a slower rate, supporting gross margin improvements.

Gross profit margins improved slightly to approximately 45.3% in Q2 2026 compared to mid-40s historically. Operating income ratio rose to about 22.4% recently from roughly 20% in 2023, reflecting operational leverage benefits and efficient SG&A expenses control. Net margins are healthy at 19.2%, supported by stable tax expenses and controlled interest expenses.

Earnings demonstrate strong quality with consistent operating income growth and effective cost management. The sizeable interest income relative to interest expense contributes positively while maintaining conservative provisioning. The absence of large non-recurring items suggests sustainable earnings power.

NU’s revenue grew approximately 67% year-over-year from $11.1 billion in 2024 to $15.9 billion in 2025, and Q2 2026 revenue shows a 22% increase over Q2 2025. This robust top-line expansion illustrates strong underlying demand and successful market penetration in Latin America.

Net income has escalated from about $1.97 billion in 2024 to $2.87 billion in 2025, marking a 46% increase. Sequential quarterly EPS has risen steadily from $0.12 in Q1 2025 to $0.22 in Q2 2026, reflecting strong bottom-line momentum.

Key growth contributors include expanding loan book sizes, increased customer adoption of digital banking products, cumulative network effects in payments, and higher interest income driven by rising lending volumes and interest rate environment.

Growth is primarily organic and driven by expanding market share in underbanked populations rather than acquisitive strategies, reflecting high sustainability. The scalability of its digital platform supports long-term margin expansion.

Gross margins have hovered near 45%, with operating margins improving from around 20% to 22% in recent quarters, while net margins approached 19% as of the latest reporting period.

ROE and ROA metrics, though not specifically provided, can be inferred as improving given net income growth relative to steady share counts and capital deployment focused on technology and credit expansion.

Given ongoing scale benefits and technology-driven efficiencies, margins appear sustainable unless offset by increased credit losses or regulatory pressures in core markets.
