From Global CEO João Vitor Menin CEO Letter João Vitor Menin Inter&Co Global CEO 2 We are off to a strong start in 2025, delivering record numbers that showcase our ability to continue to grow while increasing profitability. Inter, by design, embodies the transformation of the banking industry in Brazil. From our focus on innovation and efficient digital distribution of financial products and services, to expanding benefits and lowering costs for all our clients, we are building trust and long-term relationships that will be mutually rewarding for years to come. In the first quarter of 2025, we reached 38 million clients in our ecosystem, with 21 million active users. We have added one million new active clients every quarter for the past two years. The scalability of our business model is proven, and we are increasingly integrating AI tools that allow us to continuously customize the client experience, boosting our activation and engagement rates. We are especially excited about the exceptional engagement with Pix, the significant uptake of our loyalty program Loop, and the record number of clients utilizing our credit products. Additionally, we are making progress with innovative loan offerings such as PIX Finance, Buy Now Pay Later, and new digital Private Payroll loans. We continue to deliver growth and profitability, reaching another record level of net income for a single quarter, with EBT of R$358 million—31% growth compared to 1Q24—and ROE of nearly 13%, vs. 9.2% in 1Q24. Other highlights include improvements in asset quality, with NPL decreasing to 4.1% from 4.8% in 1Q24, a result of our ongoing efforts to enhance underwriting standards and collection processes. While growth remains our primary driver, we remain focused on managing expenses as we work toward our 30% efficiency ratio north star. Our growth prospects for 2025 remain robust despite a challenging macro scenario. Our commitment to staying ahead of trends and proactively seizing growth opportunities keeps us confident that 2025 will be a landmark year in our 60/30/30 journey. As always, I am deeply grateful to all our dedicated employees, valued clients, strategic partners, and supportive shareholders. Thank you!

Our activation rate edged up to 57.2% with continued enhancements in hyper-personalization and an updated onboarding process boosted by WhatsApp communication. Tailored offers allow us to better cross-sell and provide products to specific clusters, generating additional revenue and reducing churn. Business accounts increased by 23% YoY, representing 6% of total clients. With an activation rate of 80%, the growth in the segment offers many opportunities to increase cross-selling, especially into secured working capital credit products such as “FGI PEAC” and “Pronampe”. We currently rank in the top 15 and 10 underwriters of these products, respectively, leading among the digital banks1. We have personalized the homepage based on each client’s interactions with Babi, our customer service chatbot, increasing conversion. Location features also help us target clients at the right moment with appropriate services. For example, while traveling, we can offer Global Account products, travel insurance, and gift cards through Intershop. For 2Q25, we are launching a new marketing campaign to continue to increase our brand awareness in addition to targeting credit products such as Pix Finance and the new Private Payroll loan.

On the other hand, our efforts to optimize operations and streamline expenses have allowed us to achieve higher levels of efficiency, decreasing our CTS to R$13.1, a 6% QoQ improvement. In examining cohorts, we observed acceleration in revenue in both new and older cohorts. We surpassed R$116 gross ARPAC in mature cohorts, demonstrating the sustainable long-term relationship we are building with our clients.

We launched Private Payroll loans late March and reached R$197 million portfolio in just 10 days. With our 100% digital approach, this product offers significant opportunity and is a perfect fit with our business model: digital, low-cost distribution, scalable and collateralized, with little to no overlap with other credit products we currently offer. The personal loan portfolio also increased with the revamp of our digital public payroll loan offer. Underwriting grew 72% YoY with the launch of the 100% digital offer and portability. The new digital format has also benefited our repricing strategy, facilitating the refinancing of the existing legacy portfolio. Despite being a seasonally weaker quarter, the Consumer Finance 2.0 portfolio, which includes Pix Financing, BNPL, and Overdraft, reached R$920 million, a 30% growth QoQ, as we continue to scale up the new lines in our platform, for example: 8% of Intershop GMV was converted into BNPL operations during the 1Q25.

Even during a quarter seasonally marked by lower liquidity and consequent higher default rates, we sustained ongoing improvements in our credit quality, a result of enhanced underwriting capabilities and collection process. The NPL ratio over 90 days demonstrated consistent improvement, decreasing by 15 bps during the quarter and 76 bps YoY. NPL formation remained stable at 1.2%, a decrease of 31 bps over the last 12 months. Main improvements came from the credit card portfolio and the new cohorts' performance. Since 3Q24, Stage 3 formation was impacted to converge with CMN Resolution No. 4966/2021, which establishes a minimum cure period for renegotiated portfolios that must remain in Stage 3. Renegotiations after 3Q24 have moved to Stage 3, while the older ones remained in Stage 2, thus explaining the gap between stage 3 and NPL formation since then.

Growth was driven primarily by time deposits, which increased almost 50%. The 1Q’s are typically characterized by lower liquidity in the system, which explains the decrease in transactional deposits compared to the previous quarter. Our active clients have an average of approximately R$2,000 in deposits, a strong indicator of their use of Inter as their main financial institution for daily transactions. Our all-in cost of funding stood at 63.8% of CDI in the quarter, continuing to be an industry leading indicator among Brazilian banks and fintechs6. Nominal cost of funding increased in 1Q25 due to a higher Selic rate as a result of the tightening monetary cycle.

In 1Q25, we achieved R$3.2 billion in total gross revenue and R$1.8 billion in net revenue, a YoY growth of 38% and 31%, respectively. Strong performance in net interest income was primarily driven by ongoing repricing and new liquidity allocation. The growth in fee revenues was affected by seasonal trends during the quarter, particularly due to decreases in TPV and GMV as well as mentioned changes from the CMN Resolution No. 4966/2021.

To sustain this advantage over time, we have established an ROE-driven underwriting framework based on the return on allocated capital. To further optimize our capital structure, we have focused on increasing our capital base at the holding level. In 1Q25 the excess capital at the holding level reached R$1.3 billion. At the banking level (Banco Inter S.A.) the Basel ratio decreased to 14.7%, primarily due to growth in the credit portfolio. On April 30, Banco Inter S.A. successfully issued R$500 million in Subordinated Financial Bills, which will compose the Additional Capital of Banco Inter’s Reference Equity (Tier II).
