B3SA3

B3 S.A. – Brasil, Bolsa, Balcão, traded on B3 under the ticker B3SA3, is the main financial and capital markets infrastructure in Brazil and one of the largest global companies in this segment. The company was created in 2017 from the combination of BM&FBOVESPA S.A. – Bolsa de Valores, Mercadorias e Futuros and Cetip S.A. – Mercados Organizados, bringing together in a single organization the activities of stock exchange, derivatives, and registration and custody of fixed-income securities and financing. The merger consolidated a vertically integrated business model with a strong technological base and a focus on operational efficiency and risk management, and marked a consolidation movement of the Brazilian capital market infrastructure into a single listed company whose shares are widely traded on the spot market.

B3’s core activity is the management of organized securities markets, both on-exchange and in the organized over-the-counter environment. The company operates trading, clearing, settlement and registration systems for different asset classes, including equities, private fixed-income securities, interest rate, FX, inflation and commodities derivatives, as well as structured transactions. In these markets, B3 also provides central depository services, taking on book-entry custody and corporate actions processing for assets, and acts as central counterparty in various transactions, positioning itself between buyers and sellers and mitigating settlement risk. This set of activities positions the company as a critical infrastructure for the day-to-day functioning of the Brazilian financial market, with revenues derived from trading, post-trading, custody, registration fees and services associated with issuer listing and public offerings.

B3’s businesses are organized into operating segments that reflect its main revenue lines. In the Listed – Equities and equity instruments segment, the company offers integrated trading, central counterparty, clearing, settlement and depository services for equities, BDRs, options and derivatives on equities and indices. Remuneration in this segment is predominantly based on percentages of the traded financial volume and per-contract revenues in derivatives, in addition to custody and securities lending service fees. In the Listed – Interest rates, currencies and commodities segment, B3 manages financial derivatives contracts linked to Brazilian real interest rates, exchange rates, inflation, as well as commodities derivatives and spot FX, charging registration, exchange, maintenance and settlement fees that make up the revenue per contract. In the OTC segment, the company registers and safekeeps corporate and banking fixed-income instruments, OTC derivatives and other assets, including debentures, promissory notes, CRIs, CRAs, fund shares and agribusiness securities, in addition to operating Tesouro Direto in partnership with the Brazilian National Treasury.

Beyond its direct role in securities markets, B3 has developed an important financing infrastructure arm, focused on auto, real estate and insurance credit. Through integrated electronic systems, the company centralizes information on vehicle liens in the Sistema Nacional de Gravames, offers platforms for sending and making credit information available among financial institutions, traffic authorities and the Central Bank, and maintains a real estate platform dedicated to property appraisal, contract registration and collateral. In this context, it also operates as a registry entity for insurance transactions, accredited by the Superintendence of Private Insurance, through the Insurconnect system. These activities broaden B3’s revenue diversification beyond the strict exchange market, anchored in service contracts with financial agents and fees for registration, maintenance and information queries.

Recent diversification has included expansion into technology, data and analytics, following a trend seen in global exchanges. B3 has consolidated a Technology, Data and Services segment, which encompasses trading workstations, high-capacity connections, servers for trading desks, licensing of OTC registration systems and real-time, delayed or end-of-day market data services. The company began to leverage the intelligence generated by the data that flow through its systems, drawing on acquisitions such as Neoway and Neurotech, specialized in big data, artificial intelligence and machine learning, to offer analytical solutions to financial institutions, credit and retail companies, and KYC, compliance and anti-money laundering services. The creation of the Dimensa joint venture, in partnership with TOTVS, reinforced the supply of software and SaaS solutions for the financial segment, while the B3 Digitas structure and the L4 Venture Builder vehicle expanded its presence in digital assets and in the innovation ecosystem for financial services.

B3 operates in a highly regulated market and is supervised by different governmental bodies. In the securities domain, its activities are mainly regulated by the Brazilian Securities and Exchange Commission, the National Monetary Council and the Central Bank of Brazil, and are framed by Brazilian Payment System legislation for its systemically important clearing and settlement houses. In the insurance, pension and capitalization markets, relevant regulation is issued by the Superintendence of Private Insurance, while activities related to auto financing involve interaction with the National Traffic Secretariat, responsible for registering restrictions on vehicles. As a market operator, registry entity and central securities depository, B3 also holds rulemaking and supervisory powers over participants with access to its systems, establishing rules of conduct, operational standards, mechanisms to mitigate default risk and applying penalties in case of non-compliance with rules, complementing governmental supervision.

B3’s business model is technology-intensive and depends on high-capacity, low-latency platforms. The company invested in the PUMA Trading System, developed in partnership with CME Group, as a multi-market, multi-asset platform for electronic trading of equities, derivatives and private fixed income. Over the years, this system has undergone infrastructure and functionality upgrades, such as processing enhancements, real-time risk assessment models and mechanisms for interaction between order books. In post-trading, the company implemented B3 Clearing, which integrates registration, clearing, settlement and risk management of several asset classes, supported by the RTC software and the CORE risk model, allowing unified treatment of collateral and risk calculation for multiple markets. This integration has resulted in efficiency gains in collateral allocation and reinforced B3’s position as the central infrastructure for the Brazilian capital market.

On the social and stakeholder engagement front, B3 maintains initiatives such as B3 Social, focused on supporting projects in the areas of health, food, micro-entrepreneurship and community businesses, having intensified its activities during the Covid-19 pandemic period. The company also carries out organizational culture projects that value proximity to clients, operational robustness and product development, seeking to align its activities with the evolution of the capital market in the country. Internationally, B3 maintains representative offices in Asia, Europe and North America, focused on institutional relations and promoting products and services to foreign participants. As a listed company with B3SA3 shares traded on B3 itself, the company is part of the universe of issuers it helps regulate and provides the market with a unique case of trading infrastructure that is both the central platform for the functioning of the Brazilian financial system and a listed asset accessible to local and international investors.
