Oi S.A.: core business model

Oi S.A. is a large integrated telecommunications group in Brazil, offering fixed-line, broadband, pay TV and corporate data services. The company historically operated one of the country’s largest fixed networks and also participated in the mobile segment before selling its mobile assets to a consortium of competitors as part of an earlier phase of its restructuring strategy, according to Oi group overview as of 10/2025. This divestment aimed to reduce leverage and allow the group to concentrate on infrastructure and fiber-based services.

Following years of high indebtedness and intense competition in Brazilian telecom, Oi sought judicial reorganization in Brazil. The restructuring framework includes plans to streamline operations, dispose of selected assets and prioritize investments in higher-return businesses, especially fiber. The company’s network reaches a broad footprint in Brazil, positioning it to serve both residential and corporate clients across diverse regions, along with wholesale services to other telecom operators, according to Oi financial information as of 11/2025.

Oi’s current business model centers on three main pillars: mass-market fixed broadband through fiber-to-the-home (FTTH), business-to-business (B2B) connectivity for enterprises and public institutions, and monetization of infrastructure assets such as backbone, backhaul and data transport networks. While legacy copper-based fixed voice services still exist, these are generally declining and are managed with an eye toward reducing maintenance costs and migrating customers to newer technologies where feasible, according to the company’s strategic presentations released in late 2025 and early 2026, as summarized by Oi strategy materials as of 01/2026.

Main revenue and product drivers for Oi S.A.

The main revenue driver for Oi S.A. is its fixed broadband business, especially fiber-based broadband delivered via FTTH connections. Fiber broadband offers higher speeds and more reliable service compared with legacy copper lines, and Brazilian households have been increasingly migrating to high-speed plans. Oi’s strategy places fiber at the center of its commercial approach, with specific targets for home passings and connected customers that the company has outlined in its strategic and financial reports, according to Oi results center as of 12/2025.

In addition to residential broadband, corporate and wholesale services represent an important revenue stream. Oi provides data links, VPNs, cloud connectivity and other telecom solutions to businesses and public sector clients, leveraging its backbone network across Brazil. These enterprise contracts typically feature longer terms and can generate relatively stable cash flows compared with highly promotional retail consumer segments, making them valuable within the group’s restructured portfolio. The company has indicated in its presentations that it aims to deepen relationships with corporate clients and expand value-added services on top of basic connectivity, according to Oi corporate services overview as of 09/2025.

Another important element is infrastructure monetization. Oi controls extensive fiber backbone and backhaul networks, which can be used to provide capacity to other telecom operators, internet service providers and content delivery players. Monetizing this infrastructure through wholesale contracts or potential partnerships enables Oi to extract value from its network assets beyond the retail broadband base. The company has also explored structural alternatives, such as selling stakes in infrastructure vehicles or forming joint ventures, to reduce debt while maintaining operational access to the network, as outlined in its restructuring documentation and investor materials, according to Oi releases as of 10/2025.

Legacy services, including fixed voice and some pay TV offerings, continue to contribute revenue but are in structural decline as Brazilian consumers shift to mobile data, over-the-top video and digital voice solutions. Oi’s restructuring plans typically present these segments as cash-management areas where the focus is on preserving margin and limiting capital expenditure, rather than on aggressive growth. Over time, the mix of revenues is expected to tilt further toward fiber and enterprise services, reflecting broader telecom industry trends in Brazil, according to sector commentary referenced in the company’s strategic presentations and local regulatory statistics summarized by Oi market data compilation as of 08/2025.

Why Oi S.A. matters for US investors

For US investors, Oi S.A. represents exposure to Brazil’s telecom and broadband market, which combines emerging-market growth characteristics with regulatory and currency risks. Historically, Oi has been accessible in the United States via over-the-counter instruments and American depositary receipts, although liquidity and availability can vary over time, especially amid restructuring. This means that price movements may be more volatile than those of larger US-listed telecom groups, and investors need to pay close attention to corporate actions and court decisions affecting the capital structure, as highlighted in the company’s communications during its reorganization, according to Oi press releases as of 01/2026.

Brazil is one of the largest telecom markets in Latin America, with a large addressable base for broadband and digital services. US investors seeking geographic diversification sometimes look at Brazilian telecom names as a way to gain exposure to local consumer and enterprise data usage. Oi’s focus on fiber and infrastructure aligns with long-term trends toward higher bandwidth and digitalization. However, unlike some peers with stronger balance sheets, Oi remains in a court-supervised process that introduces additional uncertainty around equity recovery value, dilution and potential future capital measures. This requires careful assessment of restructuring milestones and legal outcomes, according to Oi investor information as of 12/2025.

Currency is another factor for US investors. Oi’s primary listing is in Brazil and its financial statements are denominated in Brazilian real. Any investment from the US is exposed not only to the company’s operational performance and restructuring path, but also to movements in the BRL/USD exchange rate. Periods of macroeconomic volatility in Brazil, including shifts in interest rates and inflation, can have a material impact on the value of Brazilian equities in dollar terms. Investors following Oi typically track macro indicators and regulatory developments alongside company-specific news and court rulings, as seen in the company’s commentary around macro conditions in its earnings releases in 2025, summarized by Oi results center as of 11/2025.

Conclusion

Oi S.A. remains a complex and restructuring-focused telecom story, centered on the Brazilian fixed and broadband markets with an emphasis on fiber and infrastructure assets. The company’s business model has shifted away from mobile operations toward high-speed broadband, enterprise connectivity and network monetization, reflecting both strategic choices and the constraints imposed by its high leverage and court-supervised reorganization. For US investors, the stock offers targeted exposure to Brazilian telecom demand but comes with significant risks tied to the ongoing restructuring process, local macroeconomic conditions and currency fluctuations. Monitoring legal milestones, capital structure changes and execution on fiber and enterprise growth will be key to understanding how the company’s risk-reward profile evolves over time.
