About Inter&Co We are Inter, the Super App for your financial life

João Vitor Menin CEO Global Inter&Co Message from the Global C E O GRI2-22 In 2024, we had many reasons to celebrate: Inter achieved extraordinary milestones, expanding its client base to over 36 million. These results are the outcome of our consistent strategy based on pioneering spirit, innovation, technology, efficiency, and the creation of solutions that not only meet but exceed the expectations of our clients. Each of our seven business verticals played an important role in building a truly integrated ecosystem, where everything connects in a natural way. What makes our strategy special is how it works in practice: when we expand our product and service offerings, we are able to provide an increasingly better experience for our clients. In turn, these clients become more satisfied, engaged, and use more of our products, strengthening the connections within our ecosystem. This movement creates a virtuous circle, generating scale and efficiency gains. The results we achieve are constantly reinvested in innovation, new products, and improving the client experience. It is this dynamic that allows us to maintain a consistent and sustainable growth path. More than just numbers, we build a business model that continuously strengthens itself, in which each new client and each new product contribute to a more robust and complete ecosystem. This is how we continue to evolve and create value for all our stakeholders. Guided by our innovative DNA, we expanded our portfolio with the launch of products aimed at simplifying and transforming the relationship of clients with their finances. Among them, we highlight Forum, Digital Consignment and Consumer Finance 2.0. These initiatives not only strengthen our ecosystem's proposition but also generated record results: we added 4.2 million active clients, reaching increasingly higher levels of engagement. In 2024, we continued to execute our 60/30/30 strategic plan, balancing growth, profitability, and long-term value creation, which has brought us to this point with intentionality and robustness. With every step, we are consolidating a more global ecosystem, in which technology remains as the foundation of our business. We have expanded our financial solutions and payment offerings to people in different countries, always seeking to combine practicality, convenience, and savings in a single place. Looking ahead to 2025, our vision for the future is clear: to continue creating value for all our stakeholders while consolidating ourselves as a global Super App that unites, in a single platform, products and services that make everyday life easier for people in many places around the world. With this purpose, we continue to innovate, making our clients’ financial lives increasingly simple, smart, and connected. 4Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

At Inter, innovation transcends being simply a strategic choice – it represents the very core of our identity and purpose." Among its many remarkable achievements, a particularly significant milestone in 2022 was the comprehensive corporate reorganization that facilitated the migration of Banco Inter S.A.'s entire shareholder base from B3 S.A. – Brasil, Bolsa, Balcão (B3) in Brazil to the newly established holding company Inter&Co, Inc., which subsequently secured its listing on Nasdaq in the United States. This strategic corporate restructuring substantially expanded Inter's access to the international investment community through one of the world's most prestigious and largest stock exchanges, which serves as the trading hub for a major concentration of global technology industry leaders. On June 23, 2022, subsequent to the migration of Banco Inter's shareholder base to Inter&Co, the company's securities became listed on the Nasdaq Stock Market, the United States exchange, trading under the symbol INTR. Concurrently, Brazilian Depositary Receipts (BDRs) backed by Inter&Co's Class A ordinary shares commenced trading on B3 S.A. – Brasil, Bolsa, Balcão (B3) under the symbol INBR32. The transaction facilitated Inter's strengthening of its position as a Global Technology Company and the reinforcement of its corporate governance structure, guaranteeing evaluation processes and metrics that recognize and reward sustainable long-term growth. 6 About Inter&Co GRI2-2; 2-6 Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

Our technology 17 With this foundation, we fully leverage digital advantages to maintain a highly scalable and replicable operation, with cost efficiency and implementation speed in various markets and products, enabling our ecosystem’s network effect to become stronger over time. Information processing We were the first bank in Latin America to operate 100% in the cloud – a model that brings several advantages, such as scalability and automation, but also poses a challenge: to build an application capable of supporting the large volume of requests generated by the simultaneous navigation of millions of clients. To address this, in 2020 we developed our own API Gateway, a tool capable of processing about 2 million requests per minute at a cost ten times lower than what was offered by the market at the time. With fast response times – about one second – and high customization potential, the Inter API Gateway delivers a smooth browsing experience for clients, efficiently processing a large volume of data: +3.400 Microservices available +191k Cash-in transactions (such as PIX, transfers, deposits, and others) performed per hour on the Super App +25 Petabytes of data stored in the data lake 17,5 million daily logins recorded, on average, from December 1 to 31, 2024 We go beyond what a bank or services platform can offer – at our core, we are now a technology company, prepared to leverage all the advantages of machine learning, artificial intelligence, and digital infrastructure to provide clients with a pleasant, intuitive, and increasingly personalized experience.

Artificial Intelligence Just three months after the launch of ChatGPT by OpenAI, we made InterGPT available to all employees: an internal generative AI capable of creating images, assisting developers, and answering questions.

The channel is managed by a third-party company, ensuring the confidentiality of the whistleblower, the accused, and all those involved in the investigation, as well as the content of the complaints. Reports can be made 24 hours a day, 7 days a week, anonymously or not, through a link on the intranet, the institutional website or via phone: • 0800 887 0077 – residents in Brazil • 1-800-246-4924 – residents in the United States and Canada We are committed to creating a work environment free from harassment, intimidation, abuse, or threats, both among employees and in interactions with society. All reports received are analyzed by the Compliance area, based on the principles of confidentiality, impartiality, and secrecy, and are supported by and report to the Ethics Subcommittee. In addition to the Ethics Channel, our employees have other communication channels with the Compliance area for advice and clarification on appropriate business conduct in different corporate situations, such as email, a dedicated Compliance channel on the Slack platform (accessible to all employees), and during both in- person and e-learning training sessions. Consequence Management We have a Disciplinary Actions Policy that aims to inform, guide and discipline the expected conduct of Administrators, employees and third parties, when applicable, in addition to determining disciplinary measures for cases of violations of the Code of Conduct and Ethics, internal standards and applicable regulations¹. 28 These measures may have an advisory or disciplinary nature, including from warnings to suspension, dismissal for just cause, and when applicable, civil and criminal procedures. In 2024, no cases of discrimination were reported through the Ethics Channel. ¹Note: Laws or jurisdictional regulations applicable to complainants: CMN Resolution No. 4,859/2020; Decree No. 11,129/2022; Law No. 12,846/2013 – Anti- corruption Law; FCPA – Foreign Corrupt Practices Act - 18 US Code § 201 – Bribery of public officials and witnesses; DOJ Publications – Department of Justice; United Kingdom Bribery Act 2010..

Ombudsman In line with our approach of putting the client at the center of the business, welcoming their feedback transparently, independently, and efficiently, we have an Ombudsman area dedicated to quickly identifying any negative impacts, activating the responsible areas, and ensuring an appropriate response for these stakeholders, thus promoting continuous process and experience improvement. Requests can be received through internal channels (phone, chat, email, and website form) and, when necessary, through external channels, such as the Central Bank, Consumidor.gov, Procon, B3, CVM, among others. The Ombudsman prioritizes internal resolution of issues, mitigating clients’ need to resort to external channels. The analysis of feedback follows a flow established for identification and handling: complaint receipt, CRM registration, analysis, and referral to the business areas. After receiving feedback, a response is prepared and sent to the client and regulatory agencies, when necessary. By implementing measures such as automating feedback via APIs and RPAs, 95% of requests are registered automatically, accelerating the process of registering and classifying complaints. The Ombudsman uses metrics such as record volume, reasons for complaints, and proposed solutions, in addition to ongoing feedback from clients and internal areas, to implement process and user journey improvements, ensuring that complaint mechanisms are effective and meet their needs. Externally, we maintain a permanent commitment to transparent and constructive dialogue with clients, shareholders, and business partners. That’s why we provide other service channels, such as chat, phone, and email, enabling the submission of questions, concerns, and suggestions. 29Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

Information security is a fundamental pillar for us, being essential to protecting both client privacy and our data and systems, ensuring business continuity. We maintain a strong commitment to complying with current legislation and our internal standards, implementing robust mechanisms and controls based on market-recognized frameworks, such as ISO 27002 (Information Security Management), CIS Controls (set of priority controls for cyber defense), and the NIST Cybersecurity Framework (National Institute of Standards and Technology). All information assets receive the appropriate level of protection, according to their importance and ownership. Information created or derived from business processes is regarded as organizational property and requires specific and continuous protection. The maturity of information security at Inter is continuously monitored, with oversight of the performance of various operational controls and action plans. The results of these analyses are discussed in technical and executive forums, promoting strategic decisions and the direction of new investments. We also maintain a compliance index, measured monthly, composed of indicators from different areas, including privacy and information security. Among the main items monitored are phishing attempts (digital fraud), data mapping, and incidents involving the incorrect transmission of information. Non-compliance with these indicators is treated as a relevant operational risk. Data Security and Privacy GRI3-3: Information security and data privacy; 418-1; Data protection strategies We adopt two main pillars in our data protection strategy: Vulnerability analysis: regularly conducted by internal specialists, who perform detailed assessments to identify weaknesses in systems and applications. Penetration testing: real-world attack simulations, executed both by internal teams and in partnership with specialized companies, to identify vulnerabilities under conditions close to the real risk environment. The results are analyzed by the offensive security team and forwarded for immediate correction by the responsible areas. Vulnerability management is based on methodologies such as OWASP Risk Rating (Open Worldwide Application Security Project) and MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge). This process provides a clear view of our security posture and facilitates strategic decisions for remediations and investments. 30 Our Ecosystem Our Ecosystem The principles that guide information handling at Inter: Confidentiality Integrity Availability Authenticity Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

Information security governance We also have a dedicated privacy area and a designated DPO (Data Protection Officer) in Brazil, as described in the Privacy Policy available on our website. Our contracts with suppliers include specific data protection clauses that make direct reference to the Company’s Privacy Policy, establishing the responsibility of contracted companies to follow all established guidelines. We conduct periodic internal audits to verify compliance with the Privacy Policy and hire external audits carried out by specialized partners to identify additional opportunities for improvement. The IT Services department also performs annual audits of our most critical suppliers, assessing aspects such as data protection, privacy, and information security. We also invest heavily in ongoing training for employees, with periodic information security awareness programs. The training covers topics such as secure authentication, social engineering, phishing attack identification, handling sensitive data, incident reporting, and security practices in both physical and digital environments. 31Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

ESG We have more than 36 million clients and 4,000 employees

Employees We believe in people’s potential and the positive impact they can generate when they operate in an environment that values autonomy, belonging, and the encouragement of individual development. That’s why our employees’ organizational culture promotes experimentation, proactivity, and collaboration in daily routines—essential elements to achieve collective goals and to build innovative solutions. Cultural guidelines: Feedback An open culture, made of people who know how to listen to others and speak their minds, combining empathy and assertiveness. Spark A culture of curiosity and passion, where one always goes beyond. 33 Focus A culture of focused people, who know where they are going, and who value efficiency and excellence. Do together A culture of boldness to accomplish, experiment and take risks, with collaboration and resilience. All our employees are covered by Collective Labor Agreements and have their free right of association respected. We also value building an environment free from discrimination of any nature, whether based on race, gender, religion, age or sexual orientation.

The year 2024 marked our transition into a new cycle, focusing on performance, operational efficiency, and the delivery of sustainable results— especially considering record revenue, profitability, and client base. In this context, people play a central role in executing our strategy. To sustain the accelerated growth of operations and maintain our focus on profitability, we reorganized ourselves based on more strategic allocation of resources, recognizing that human capital is essential to strengthen the operation and drive results. After the institutional restructuring in 2023— which included a 19.9% reduction in headcount— in 2024, hiring resumed in key areas such as IT, Branding, Risk, and Tax teams. The goal was to strengthen operations, increase profitability, and support the continuous growth of our client base.

Individual performance 35 Performance of business areas (not applicable to Compliance, Internal Controls, and Risk Management areas) Performance of the Inter Group companies as a whole. We understand compensation as one of the main pillars of people management, serving not only as a mechanism to attract and retain talent, but also as a strategic tool for engagement, performance, and recognition of employees. At Inter&Co, the determination of individual compensation for employees and Senior Management follows the Remuneration Management Policy and current salary table, reviewed periodically with the support of specialized consultants and based on market salary surveys. Governance on the topic is handled by the People and Compensation Committee, responsible for the management and annual review of the policy, ensuring its adequacy and competitiveness. Updates and improvements are validated by the Board of Directors. Variable compensation We have variable compensation programs, paid annually to all employees under the CLT regime and Senior Management members, with the following objectives: • Make compensation more attractive and competitive, aligned with the organization’s strategic objectives • Recognize the individual effort of employees who achieve expected results • Value teamwork in building and evolving Inter&Co • Reward professionals with technical and behavioral skills essential for their roles • Stimulate team engagement in business strategies • Accelerate employees’ personal and professional growth Compensation GRI2-19;2-20; 202-1 Criteria for variable compensation 1 2 3 4 Relationship between the above-mentioned performances and the risks assumed by the Executives.

Suppliers 36 Respect for human dignity is a pillar of our operations and the minimum we expect from our suppliers and work partners, who must act in compliance with Inter’s Code of Conduct and Ethics. To ensure compliance throughout our value chain, all of Inter’s suppliers undergo Compliance due diligence— which includes analyses related to corruption, integrity, information security, human rights, and conflict of interest—and are monitored annually by the Compliance area. In 2024, there was no identified involvement of any supplier in child labor or conditions analogous to slavery, as verified through the Ministry of Labor and Employment’s list, using compliance tools adopted by the Company. Over the years, we have established our trajectory as Brazil's first digital bank, evolving into a complete financial solutions ecosystem. More than just offering fee-free services, we are committed to promoting inclusion and reducing inequality, expanding public access to the financial system. This commitment goes beyond technological innovation. As we expand our operations, we also strengthen our social responsibility, focusing on generating positive impact. In 2024, this area produced initiatives such as: Programadores do Amanhã (Tomorrow’s Developers) Through a partnership with the Programadores do Amanhã project, we offer a free online programming course aimed at young people aged 16 to 21 in socially vulnerable situations, with priority for Black, Brown, and Indigenous students, as well as a 50% quota reserved for women. The 12-month course goes beyond technical content, including English classes, psychological support, and job market preparation. As part of the partnership, Inter provided financial support and developed an exclusive financial education module to help students gain autonomy and financial planning skills when entering the job market. Altogether, 300 young people participated in the initiative in 2024, with an investment of R$ 518 thousand made by Inter, reinforcing our role as agents of social transformation and promoters of diversity in the technology sector. Support for Rio Grande do Sul In response to the floods that affected more than 400 municipalities in Rio Grande do Sul, we promoted a donation campaign from May 6 to 13. About 25,000 clients donated R$ 1.2 million, which was matched by Inter&Co, totaling R$ 2.5 million transferred to SOS Rio Grande do Sul via the State Government’s official Pix. In addition to the campaign, we suspended the collection of mortgage installments for clients in the region for three months, allowing repayments to resume in August. This measure reaffirms our commitment to social responsibility. Support for impact projects via tax incentive laws In 2024, we allocated more than R$ 10 million to social and incentivized projects throughout Brazil, reaffirming our commitment to human, cultural, and social development. Donations spanned various areas, using incentive laws and programs focused on inclusion and health.

Promoting Financial Education GRI 3-3 – Financial education; 203-2 Financial education is a fundamental pillar of our strategy, which sees the topic as a tool to empower people to make responsible and smart decisions in their financial lives. We consider the acquisition of these skills to be extremely important for achieving quality of life and exercising citizenship. Therefore, the subject is addressed transversally within the company, through informative and personalized content for clients, among other initiatives. In addition to content on Inter’s blog, there are also free courses, features such as the “Bússola do Inter” (Inter’s Compass), with guidance on expenses and income, and the Inter You digital account, aimed at teenagers—all designed to prepare clients to make informed financial decisions. Knowledge to Invest In 2024, we also created a partnership with the National Treasury Department, B3, and the Me Poupe! platform to broaden the public’s knowledge of Treasury Direct. The goal is to show that this is a secure and accessible investment option for all profiles, especially beginners. Currently, about 2.6 million Brazilians invest in Treasury Direct, representing just over 1% of the population. At Inter, this number is already around 350,000 clients, which corresponds to one of the largest market shares, at 13%. The initiative included educational content published on Inter’s social networks and those of Nathalia Arcuri, influencer and founder of Me Poupe!, Brazil’s leading finance personality. In addition to the campaign, clients gained exclusive access to benefits such as the “Xô Dureza” course from Me Poupe+ and tips on financial organization and first investments.

In addition to news, the channel also offers analyses and tips on stocks, investment funds, cryptocurrencies, and other relevant topics, and can be accessed via Spotify and other platforms. Game Show do Inter To encourage conversations about finances, we invited actress and comedian Tatá Werneck to host game shows with celebrities. The first edition brought together artists such as João Vicente, Pequena Lô, and Douglas Silva to promote relaxed and lighthearted conversations about financial management, and to show how Inter can make life easier for its account holders. In the second edition, the host interviewed famous couples and discussed finances in relationships. The initiative was born out of surveys conducted by CNDL, SPC, and the Central Bank, which show that 66% of couples avoid talking about finances, while 21% only discuss the subject in times of difficulty. 37Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

The program was part of the second phase of the “You didn’t know you needed it, until you became Inter” campaign. The show featured couples such as Otaviano Costa and Flávia Alessandra, and Aline Wirley and Igor Rickli. During the games, guests shared their financial choices and tested their harmony in managing their finances. Inter Educa Our financial education portal that offers courses and exclusive content for those wanting to learn about investing, financial markets, and financial education in general. The courses are delivered by experienced professionals and finance market specialists. The platform offers content for different audiences, from beginners to more advanced investors. Content can be accessed through Banco Inter’s Super App. In 2024, we expanded our offering of free courses on the Inter Educa platform with the launch of the course “Do Zero à Automação” (“From Zero to Automation”), an initiative supported by B3. Aimed at beginners, the classes provide a practical introduction to process automation, covering basic concepts through to the application of tools that streamline routine tasks. From there, students can use the automations to start trading on the exchange and to carry out risk management. Bússola do Inter A feature integrated into the Super App that facilitates financial management, allowing clients to intuitively organize and track their finances. The tool offers features such as automatic transaction categorization, detailed visualization of income and expenses, as well as customization of expense categories. With Inter’s Compass, users can view transactions in three categories: Income (revenues such as salary and cashback), Expenses (spending on food, bills, shopping, among others), and General (consolidated balance for the period). In addition, interactive charts help analyze spending distribution, allowing for clearer budget monitoring. Inter You A free digital account designed for teenagers aged 13 to 17, aimed at promoting financial education and fostering autonomy in money management. With this account, users can make Pix transfers, use a debit card, top up their cell phone, shop at Inter Shop, buy Gift Cards, and invest in various options, except Home Broker, Treasury Direct, and Private Pension. Only clients over 18 can apply for a credit card. 38Our Ecosystem Corporate GovernanceCorporate Governance ESGESG Vision for the futureVision for the future AttachmentsAttachments About InterCoAbout Inter&Co

Energy Efficiency GRI302-1; 302-3 We were responsible for revolutionizing the financial sector by becoming the first bank in Brazil to offer a 100%digital checking account. Our business model, which can offer products and services without the need for physical branches, represents much more than innovation: it is a model intrinsically aligned with a low-carbon economy and a strong commitment to sustainability. 39 Inter’sheadquarters, located inBelo Horizonte, Minas Gerais, is anexample of eco-efficiency. The buildingthat housesthe office isdoubly certified by the international Leadership in Energy and Environmental Development (LEED)seal, inthe Goldcategory, and by the Procel energyefficiency seal. In2024, we achieveda reduction of more than87%in the energyintensity rate comparedto the previousyear. The index, whichconsidered the ratio between absolute energyconsumption and Inter’s annual revenue, dropped from1.57to 0.19. This variation reflects ourongoing pursuitof greater operational efficiency and compliance with ESG principles. Renewable energy certification Committed to adoptingsustainable practices inits operations, we have acquired I-REC (International Renewable Energy Certificates), whichensure that all the electricity consumedat ourheadquarters comes fromrenewable sources, specifically hydroelectric. Throughthese certificates, it is possible to track theorigin and amountof renewable energy consumed, ensuring transparency and integrity in theprocess. This initiative reinforces our alignmentwith environmental governance guidelines and energyefficiency. Eco-efficiency Since 2019,we have taken an active stance on the climate agenda. Among the main actions, we highlight:: • Greenhousegas emissions inventory; • Renewable energy certification; • Purchase of recycling credits; • Developmentof energyefficiency projects; • Environmental education initiatives with employeesand clients.

GRI305-1;305-2; 305-3 Compensation of GHG emissions During 2024, we offset our greenhouse gas (GHG) emissions through the acquisition of carbon credits and renewable energy certificates. These instruments support Brazilian projects focused on forest conservation in the Amazon and clean energy generation, contributing concretely to climate change mitigation. Although we have comparatively low emission levels in relation to sector peers, we maintain our commitment to neutralizing emissions, reinforcing our environmental responsibility. The financial contribution to these projects generates positive impacts on the environment as well as on the communities involved, promoting integrated social, economic, and ecological benefits. The purchase of carbon credits enables us to fund environmental projects that reduce their own greenhouse gas emissions elsewhere, acting as a mechanism for offsetting emissions. GHGProtocol The GHG Protocol (Greenhouse Gas Emissions Protocol) is an international initiative that establishes standards for the accounting and reporting of GHG emissions and removals, applicable to both the public and private sectors. Organizations are encouraged to disclose their emissions according to three scopes: • Scope 1 – Direct GHG emissions from sources owned or controlled by the organization; • Scope 2 – Indirect emissions related to electricity purchased for the organization’s operations; • Scope 3 – Indirect emissions associated with the organization’s activities that occur from sources not controlled by it, such as the supply chain, product transport, business travel, and employee commuting. GHG Emissions 40 Since 2019,we havemeasured themain sources of greenhouse gas (GHG) emissions, covering both direct and indirect emissions, and report thedata transparently through the Public EmissionsRegister of theGHG Protocol. Since publishing ourfirst inventory,we havebeen continuously recognized by the GHGProtocol for the transparency and completenessof the information reported. Regardingthe2025 cycle, based on2024 information,our inventorywasrecognized with thesilversealand will be publishedsoon, according to the program’sofficial schedule.
