Nu Holdings Ltd. Reports Second Quarter 2026 Financial Results São
Paulo, Brazil, August 13, 2026 — Nu Holdings Ltd. (NYSE: NU) (“Nu” or the “Company”), the largest digital
bank in Latin America, today released its fi nancial results for the second quarter ended June 30, 2026, prepared in accordance with
IFRS, as well as complementary managerial results. The fi nancial statements and earnings presentation are available on the Company’s
Investor Relations website at www.investors.nu, along with details of the earnings conference call to be held today at 6:00 p.m. Eastern
Time / 7:00 p.m. Brasília time. "Thirteen years ago we started with a simple hypothesis: that a bank built on technology, with
no branches and no legacy to defend, could serve hundreds of millions of people better, and at a fraction of the cost. This is no longer
a hypothesis, and we are now generating more than a billion dollars in quarterly net income. Earlier this month, we launched our bank
in Mexico, becoming the largest digital bank in the country with 16 million customers. That completes our transformation there, unlocking
capabilities we did not have before. In Brazil, we are evolving our structure, adding a full banking license to our operations. We also
launched Croma for our Super Core customers, taking the same primary banking playbook upmarket into an even larger profi t pool. Underpinning
all of it, NuFormer, our foundation model for fi nancial behavior, now powers underwriting, customer service, and growth decisions across
the company," says David Vélez, founder and global CEO of Nubank. Q2’26 Results Snapshot Below are the Q2’26 performance
highlights of Nu Holdings Ltd. Unless otherwise noted, all the growth rates presented herein are on an FX neutral basis (FXN) 1 : Operating
Highlights: ● Customer growth - Nu added approximately 4 million customers in Q2'26, reaching a total of 139 million customers
globally. In Brazil, Nu reached almost 118 million customers. In Mexico, Nu reached 15.8 million customers (and 16 million as of July,
2026), and in Colombia, Nu surpassed 5 million customers, continuing its steady pace of net additions. ● Engagement and activity
rates - ARPAC reached approximately $17 in Q2'26, growing sequentially quarter-over-quarter (QoQ) once again. Monthly activity rate expanded
sequentially to 83.5%, with Brazil surpassing 86% for the fi rst time. 1 FX neutral measures were calculated to present what such measures
in preceding periods/years would have been had exchange rates remained stable from these preceding periods/years until the date of the
Company’s more recent fi nancial information. 1 ● Efficiency Ratio - Efficiency Ratio increased to 19.5% in Q2'26 from 17.6%
in Q1'26 (21.3% in Q2'25), as real estate and marketing expenses shifted from the fi rst quarter into the second, alongside our continued
investments in international expansion. ● Asset Quality - Leading indicator 15-90 NPL ratio improved 16 bps to 4.8% in Q2'26, with
the majority of the improvement coming from seasonality, partially offset by intentional expansions into higher-risk, higher-return segments.
Product mix and other minor effects were broadly neutral. 90+ NPLs increased 35 bps to 6.9%, largely refl ecting the seasonal migration
of fi rst-quarter early delinquencies. Financial Highlights: ● Revenue, Net Interest Income (NII) and Risk-adjusted NIM - Nu's
Q2'26 gross revenue reached nearly $5.9 billion, up 39% YoY. NII reached $3.7 billion, up 9% QoQ, and Net Interest Margin expanded 180
bps to 22.9%, refl ecting portfolio growth, the mix shift toward unsecured lending, and the intentional risk expansions communicated
last quarter. Cost of Credit declined 9% QoQ to $1.7 billion, largely refl ecting the normal second-quarter improvement in early delinquencies.
As a result, Risk-adjusted NIM expanded 290 bps to 12.4%, from 9.5% in Q1'26. ● Profi tability - Gross profi t reached $2.4 billion,
up 43% YoY and 25% QoQ. Credit's contribution to gross profi t rose to 41% as it normalized in line with its expected seasonal pattern,
with fees at 25% and fl oat at 34% — all three growing in absolute dollars. Net Income reached $1.1 billion for the fi rst time
in Nubank's history, up 17% QoQ and 49% YoY. ROE closed the quarter at 33%. ● Balance Sheet and Funding - Total credit portfolio
expanded 37% YoY and 5% QoQ to $39.4 billion, with credit cards at $26 billion, unsecured lending at $10.3 billion, and secured lending
at $3.1 billion. Total deposits reached $45.3 billion, up 18% YoY and 6% QoQ, recovering Q1's seasonal outfl ows. Brazil closed at $36.4
billion, Mexico at $5.7 billion, and Colombia at $3.3 billion. In Mexico, deposits declined modestly again this quarter as part of a
deliberate deposit-optimization strategy, improving cost of funding while maintaining ample liquidity, with Mexico's loan-to-deposit
ratio at just 35%. Consolidated cost of deposits held at 88% of interbank rates, 3 p.p. lower than a year ago. Business highlights: ●
Deepening and Broadening Leadership in Brazil: Nu reached almost 118 million customers in Brazil, with the monthly activity rate surpassing
86% for the fi rst time. Nu already serves most of the Mass Market segment and is the primary bank for a high share of those customers.
It is also moving upmarket, where Ultravioleta continues to deepen primary banking relationships in the High Income segment. In July,
Nu launched Croma for Super Core customers, offering a dedicated experience, enhanced credit, and broader benefi ts designed to reward
customers for concentrating more of their fi nancial lives with Nu. Beyond consumers, Nu serves more small businesses than any other
fi nancial institution in Brazil. ● Becoming Mexico's Largest Digital Bank: With its August launch, Nu became Mexico's largest
digital bank, completing its shift from a credit-fi rst fi ntech to a full-scale institution. Customer behavior, technology, and regulation
are now all moving in the same direction: SPEI transfers below $5 grew more than 60% in the fi rst half, while new central bank rules
introduced in June, mandatory for all institutions by year-end, will standardize the payment experience across rails and strengthen network
effects. Nu reaches 16.5% of Mexico's adult population, comparable to Brazil in 2020, but cohorts monetize earlier, with ARPAC of $12.3
against $5.6 in Brazil at the same stage. Taken together, these forces create one of the most compelling opportunities Nu has seen in
Mexico. 2 ● Scaling NuFormer and Broadening AI Across the Business: Nu continues to advance NuFormer, its foundation model for
fi nancial behavior, building on one of its greatest advantages: over a decade of transaction history across more than 100 million customers.
The latest generation quadrupled context length, training speed, and inference speed, while reducing the cost of running models in production.
NuFormer is in production across three portfolios — credit cards in Brazil and Mexico, and unsecured lending in Brazil —
with SME and Colombian cards now in testing. Beyond underwriting, AI agents handle more than 60% of customer support conversations in
Brazil at or above human parity, and Nu is using AI to optimize decisions across credit, deposits, and growth. ● Credit as a Superpower,
Underpinned by Customer Primacy: Nu leads the Brazilian market in Primary Banking Relationships (PBR), and that leadership, combined
with the analytical rigor of its underwriting models and the quality of the data those relationships generate, creates a structural credit
edge. Credit performance has been steady across every income band, with 90+ delinquency improving in each since July 2025 while the peer
bank segments deteriorated, and the widest differentiation in Mass Market and Super Core. Customers with Nu as their PBR show delinquency
roughly half the portfolio average, reinforcing that customer primacy is both a growth and a credit advantage. 3 3 Key Operating and
