Nu Holdings is delivering rapid revenue and earnings growth, but rising delinquencies and a still-developing credit book keep the risk profile elevated. The report supports a Buy case on scale, profitability, and balance sheet strength.
Nu Holdings Ltd. (NU) combines exceptional growth with a balance sheet that can support further expansion. Revenue rose 43.7% year over year, earnings increased 55.9%, free cash flow reached $3.5B in 2025, and the company held $19.4B of cash at March 31, 2026 against $3.1B of debt. The shares trade at a cited reference price of $13.93, compared with an analyst consensus target of $17.98.
The central investment case is operating leverage across a large Latin American customer base. NU surpassed 135 million customers in the first quarter of 2026, reached 115 million in Brazil, crossed 15 million in Mexico, and approached 5 million in Colombia. Brazil generated roughly 7% of the addressable profit pool identified by management, while Mexico remained below 1%, leaving a substantial runway for deeper product penetration.
The main restraint is execution risk in credit. The loan portfolio grew 40% year over year to $37.2B in Q1 2026, while the 15-to-90-day nonperforming loan ratio rose to 5.0%. Late-stage 90-plus-day delinquencies eased to 6.5%, but the earnings history shows only 1 beat in 8 quarters, including a 30.0% EPS miss on August 13, 2026. For a moderate-risk investor, that combination supports a Buy rating, but not an invitation to treat every quarter as a victory lap.
Nu Holdings Ltd. operates the Nubank digital banking platform across Brazil, Mexico, Colombia, the Cayman Islands, and the United States. Its products include accounts, credit cards, unsecured and secured lending, payments, investments, insurance, cryptocurrency services, travel, mobile connectivity, and small-business banking. Founder David Vélez serves as chairman and chief executive officer.
The company has moved well beyond its original credit-card identity. Annual revenue increased from $7.7B in 2023 to $11.1B in 2024 and $15.9B in 2025. Net income increased from $1.0B to $2.0B and then $2.9B across those same years. Quarterly revenue reached $5.0B in the first quarter of 2026, while quarterly net income reached $872.1M in the financial statements.
NU listed on the New York Stock Exchange on December 9, 2021. Institutional ownership stands at 81.2%, with BlackRock holding 339.9 million shares and Morgan Stanley brokerage accounts holding 141.6 million shares. Short interest represents 0.04% of the float, so the stock's investment case rests on business execution rather than a meaningful short squeeze.
Brazil remains NU's economic engine. Management estimates that the consumer and small-business products it serves address a profit pool above $100B annually. NU's disclosed share is roughly 7%, despite its position as Brazil's largest private financial institution by customer count. The disclosed product shares are uneven: NU holds 18% of the card profit pool, 8% of unsecured lending, 4% of deposit net interest income, and less than 1% of investments and insurance.
Mexico is the most important geographic inflection point. NU grew its Mexican customer base from just over 2 million to 15 million in four years, nearly doubled ARPAC, reduced its efficiency ratio by 78 percentage points, and reached its first quarter of IFRS profitability in Q1 2026. Management estimates the Mexican profit pool for its targeted products above $40B, while NU's share remains below 1%.
Colombia is smaller but still expanding. The company approached 5 million customers in Q1 2026, and deposits continued to grow there during the quarter. Brazil, Mexico, and Colombia therefore contribute three different stages of the same model: mature scale in Brazil, an earnings inflection in Mexico, and earlier customer expansion in Colombia.
Small-business banking adds another cross-sell opportunity. NU said it had built a base of more than 5 million Brazilian SME customers at $0 customer acquisition cost and had crossed 2 million SME credit cards. New secured and unsecured lending products extend the relationship beyond the consumer account, while the company is moving from microbusinesses toward companies with more than 10 to 15 employees.

The flagship product is the integrated Nubank account and card ecosystem. Customers can use Nu personal accounts for transfers, bill payment, spending, saving, investing, and borrowing, while the Nu credit and prepaid card connects transaction activity with credit underwriting. NuPay extends the account into online purchases, and Nu Shopping adds a marketplace inside the application.
The credit engine is producing the strongest growth. NU's total credit portfolio reached $37.2B in Q1 2026, up 40% year over year. Credit cards grew 36%, unsecured lending grew 53% to $10.0B, and secured lending grew 38% while retaining an 8% mix. Total deposits reached $42.4B, up 22%, creating a funding base for the expanding loan book.
The product's strength is the monetization ladder. NU acquires a customer through a simple account or card, observes transaction behavior, then adds credit, savings, investment, insurance, or SME services. That design explains why ARPAC has expanded sequentially in every reported quarter since management began disclosing it.
NU's competitive advantage rests on scale, first-party data, internal technology, and a low-cost operating model. Management reported close to 100% employee use of AI tools, engineering throughput up more than 50% year over year, testing cycles 90% faster, and weekly token consumption nearly 10 times higher than at the start of 2026.
The company has moved its proprietary NuFormer models into credit-card decisioning in Brazil and Mexico and unsecured lending in Brazil. NU said it can value, price, and approve a personal loan in under one second using predictive net present value. AI Private Banker functions, including financial insights, payments, credit advice, and debt resolution, serve more than 15 million monthly active users.
The moat is strongest when AI improves underwriting and customer economics at the same time. NU has 135 million customers generating transaction data, a cloud-native core banking system, unified internal data, and a stated ability to move from experiment to production in days rather than quarters. Those assets can support better credit selection, faster product launches, and lower service costs.
NU has no branch-heavy operating footprint. Its platform is cloud native, its core banking systems were built internally, and its customer service, underwriting, payments, and product distribution run through the application. The company reported a Q1 2026 efficiency ratio of 17.6%, with a core ratio of 16.6% after excluding return-to-office, international expansion, and AI infrastructure investments.
The operating model also depends on deposits and funding discipline. The consolidated cost of deposits was 88% of the interbank rate in Q1 2026. Management expects the full-year 2026 efficiency ratio to land near 20%, while the maximum U.S. investment headwind in each of 2026 and 2027 is expected to remain below 100 basis points of the consolidated ratio.
Physical supply-chain risk is less relevant than technology, regulatory, funding, and data risks. NU's 20-F filing identified expected credit loss measurement as a critical audit matter because the process uses probability of default, loss given default, exposure at default, and macroeconomic variables including GDP, inflation, unemployment, and policy rates.
The global retail banking market is projected at $3.8T in 2026 and $5.2T by 2031, implying a 6.5% compound annual growth rate. Online banking represented 71.5% of 2025 retail banking revenue in the cited market research. That shift favors NU's mobile-first distribution model, although digital access also makes customer relationships easier to fragment.
Latin American fintech is growing faster than the broader banking pool. McKinsey estimates that fintech revenue in the region has expanded at roughly 40% annually over five years, with lending growing about 50% annually since 2021. The growth opportunity is attractive, but the same figures explain why NU faces intense competition from digital banks, payments platforms, and established institutions.
NU's own market data supports a long runway. Brazil's targeted consumer and SME profit pool exceeds $100B, Mexico's exceeds $40B, and NU's reported share is still roughly 7% in Brazil and below 1% in Mexico. The investment case does not require immediate global dominance. It requires continued share gains in markets where NU already has substantial customer distribution.

NU serves mass-market consumers, emerging middle-income customers, entrepreneurs, and small businesses. In Mexico, less than half of adults hold a formal credit product, according to management's Q1 2026 presentation. That customer profile gives NU room to add users who have historically had limited access to formal banking.
Engagement is high relative to the size of the base. Consolidated monthly activity held at 83% in Q1 2026, while Brazil approached 100 million monthly active customers. The company also reported ARPAC of around $16 per active customer. That combination of activity and monetization matters more than customer count alone because a large inactive base would carry little economic value.
The SME customer is an especially efficient extension of the consumer relationship. NU's more than 5 million Brazilian SME customers were largely cross-sold from its existing base, and the company had issued more than 2 million SME cards. A shared consumer and business relationship can increase retention and create multiple revenue streams from the same customer acquisition expense.
In Brazilian consumer credit, NU competes with Itaú Unibanco (ITUB), Banco Bradesco (BBD), Banco Santander Brasil (BSBR), Caixa Econômica Federal, and Banco do Brasil (BDORY). In investments, the named competitors include BTG Pactual (BPAC3), Banco Inter (INTR), Banco C6, and XP Inc. (XP).
Payments competition includes Mercado Pago, PicPay, PagBank (PAGS), StoneCo (STNE), and other digital platforms. NU therefore competes across several overlapping categories rather than against one direct peer. Its edge is the combination of account, card, credit, payments, and savings products inside one app.
Traditional banks retain scale, funding relationships, and established regulatory infrastructure. Digital competitors can move quickly and offer simple interfaces. NU's disclosed cost-to-serve and general and administrative expense per active customer were about 85% below Brazilian incumbents in its 2024 filing, while its Q1 2026 efficiency ratio remained near 18%. That cost advantage is a meaningful defense, but it must persist as the loan book becomes larger and more complex.
Brazilian household leverage is a central macro risk because NU is expanding cards and unsecured lending. Management said employment remained strong and pointed to an income tax exemption for earnings up to BRL 5,000 per month as a tailwind for disposable income and debt service capacity. These factors support borrowers, but they do not eliminate the effect of higher unemployment or weaker household income.
Credit performance also has a direct connection to macro variables. NU's audited expected credit loss framework incorporates GDP, inflation, unemployment, and the basic interest rate. A change in any of those inputs can affect provisions even before delinquency fully appears in reported results.
The regional policy environment creates both opportunity and risk. Mexico's underpenetrated banking market helped NU reach 15 million customers and break-even, while Colombia's deposits continued to grow. The U.S. expansion is being treated as a measured option, with management limiting the expected operating expense impact to less than 100 basis points of the consolidated efficiency ratio in each of 2026 and 2027.
$19.4B of cash versus $3.1B of debt leaves Nu with ample flexibility, and free cash flow reached $3.5B in 2025 even as the loan book expanded.

Its 135 million customers, $37.2B credit portfolio, $42.4B deposit base, $3.5B of 2025 free cash flow, and 17.6% Q1 efficiency ratio show a platform that is already profitable rather than merely promising. Brazil still contributes most of the economic foundation, while Mexico and Colombia provide additional expansion paths.
The investment decision comes down to whether underwriting discipline can keep pace with loan growth. Late-stage delinquencies eased to 6.5%, coverage reached 16.2% of the portfolio, and management attributed the Q1 allowance increase primarily to portfolio growth and seasonality. Those facts support the Buy rating, but the 1/8 earnings beat rate demands position sizing discipline. At prices near the cited $13.93 reference, NU offers a credible medium-term growth opportunity with our fair value estimate of $17.50.
