Oi

What Oi does

Oi S.A. is a publicly traded Brazilian telecommunications company headquartered in Rio de Janeiro, listed on the B3 exchange. Founded in the 1960s as a fixed-line operator (sources cite 1963 in firmographics and 1999 in corporate history), Oi historically competed with Vivo, Claro, and TIM across mobile, broadband, pay-TV, and long-distance voice services. After years of debt accumulation and failed restructuring, Oi filed for Chapter 11 bankruptcy protection in February 2023 and was declared bankrupt by a Rio de Janeiro court on November 11, 2025; a subsequent appellate ruling temporarily suspended the insolvency declaration while restructuring continues. During this period Oi divested major assets: the Oi TV subscription business was sold to Mileto Tecnologia in February 2025, the Oi Fibra broadband operation was transferred to NIO, the 27.2% stake in fiber-optic infrastructure company V.tal was sold to BTG Pactual for R$4.5 billion in April 2026, and 8,000 telecom towers were divested to Highline.

The company's strategic center of gravity is now Oi Soluções, a B2B technology integrator serving 43,000+ large enterprises and government institutions across all 27 Brazilian states. The portfolio combines AI (IAGO platform), cloud infrastructure management (Cloud Hub, Veeam Backup integrated with AWS), full-spectrum cybersecurity (VulneraPro Bug Bounty — first in Brazil — plus MDR, SIEM, MSS Firewall, WAF, CASB, EDR, PAM), unified communications (UC4X Cloud PBX, Hub Omnichannel), IoT/Big Data services, and managed connectivity (IP Connect, SD-WAN, IP Connect Satélite). The November 2025 completion of the UCS platform further consolidates legacy interconnection into a 100% cloud-hosted architecture across two digital stations.

Oi generates revenue primarily through recurring enterprise and government contracts (subscription-based with pay-as-you-go components), supplemented by legacy fixed-line telephony in COLR-regulated localities (R$94.90/month unlimited calls plan) and rural satellite internet in underserved regions. Cloud contracts exceeded R$62 million in 2025, with the cybersecurity portfolio growing 38% in revenue terms in 2024. Distribution is split between direct enterprise sales teams, consultant-led engagements, AWS Marketplace for cloud reselling, and contact centers for residential and SMB accounts. The company has closed physical retail stores. Oi holds Expert Partner status with Fortinet and is an AWS Public Sector Solution Provider. Operating status remains under bankruptcy trustee supervision, with key restructure mechanics (BTG Pactual DIP financing of $300 million in September 2023, V.tal asset sale finalization) reshaping the business around the Oi Soluções enterprise core.
