What Light does

Light S.A. is a publicly traded Brazilian electricity distribution and generation company headquartered in Rio de Janeiro, serving approximately 12 million people across Rio de Janeiro state under a 30-year concession contract renewed by the Brazilian Ministry of Mines and Energy in April 2026. The company operates as a regulated monopoly distributor with rates set by ANEEL, the Brazilian electricity regulator. Its core business segments are electricity distribution (serving residential and commercial customers) and generation and trading. Distribution revenue reached R$323 million in Q4 2025, a 42.5% year-over-year surge, while the generation and trading segment declined 48.2% year-over-year in the same period.

Light's product portfolio centers on regulated utility services. Residential customers access services through "Sua Casa" (Your Home) online portal, while business customers use "Sua Empresa" (Your Business) portal. The company complements its core offering with a mobile self-service app for low-voltage customers on Android and iOS, and Lia, an AI-powered virtual assistant integrated with WhatsApp for automated customer support. Smart metering infrastructure is being deployed in a Brazilian market where smart meter penetration is only 6.5%, representing a significant modernization opportunity.

Light's revenue model is predominantly usage-based regulated tariffs, with annual revenue in the R$2.4-2.9 billion range across recent years. The company entered judicial recovery in May 2023 with approximately R$11 billion in debt across more than 63,000 creditors, primarily due to high energy theft rates. Following a R$1.24 billion capital increase in June 2024, a planned R$2.2 billion debt-to-equity conversion, and the 30-year concession renewal, Light is exiting bankruptcy and recapitalizing for an aggressive capex cycle, with 2025 capital expenditure of R$1.6 billion (up 65.6% from 2024). Major institutional shareholders include BTG Pactual (14.81%) and Samambaia FIA (20.01%).

Expansion highlights5 records

Direct peers

• AES Brasil: Brazilian subsidiary of AES Corporation operating generation, transmission, and distribution businesses under regulated and merchant frameworks. Comparable in operating segments spanning distribution and generation, and as a smaller-cap publicly listed Brazilian utility facing similar capital-structure and regulatory dynamics.
• Cemig (Companhia Energética de Minas Gerais): Integrated Brazilian electric utility with regulated distribution, generation, and transmission operations centered in Minas Gerais. Comparable to Light in regulated distribution scale, generation-segment exposure, and the strategic balancing between regulated and merchant revenue streams.
• Neoenergia: One of Brazil's largest private-sector electric utilities with regulated distribution operations across multiple states. Comparable to Light in regulated distribution scale, concession-based revenue model, and capital-intensive infrastructure profile, though with greater geographic diversification across Brazil.
• Equatorial Energia: Brazilian multi-state electricity distribution and transmission operator that has built a track record of turning around underperforming concessions. Directly comparable as a regulated distribution peer with a similar strategy of acquiring and operationalizing distressed utilities, providing a benchmark for Light's post-restructuring trajectory.
• EDP Energias do Brasil: Brazilian subsidiary of EDP with regulated electricity distribution concessions serving multiple states. Comparable in customer base size, regulated revenue model, and digital-customer-engagement initiatives, making it a relevant operational and investor benchmark for Light.
• CPFL Energia: Major Brazilian electricity distribution company serving millions of customers across São Paulo and the South region under regulated concession contracts. Directly comparable in business model — regulated distribution tariffs, residential and commercial customer mix, and capex-driven growth — with stronger balance sheet and broader geographic reach.
• Enel Brasil (formerly Enel Distribuição Rio): Direct competitor operating electricity distribution concessions in Brazil, including in the Rio de Janeiro metro area. Enel is the closest peer because it competes head-to-head in the same Brazilian regulated distribution market with similar customer scale and operational exposure to non-technical losses. Notably, Enel was excluded from the recent Brazilian concession renewal round, making Light's renewal a structural differentiator.

Broad incumbents

• Engie Brasil: Major Brazilian energy company with significant generation, transmission, and distribution operations. Comparable in scale and integrated business model, particularly relevant given Light's declining generation/trading segment where Engie is a stronger incumbent.
• Eletrobras: Brazil's largest electric utility and a major federally-connected player across generation, transmission, and distribution. While not a direct geographic competitor to Light in Rio de Janeiro, Eletrobras sets the regulatory and operational benchmark for large Brazilian utilities and represents the scale ceiling for the sector.

Regional players

• ISA Cteep: Brazil's largest private-sector electric power transmission operator. While focused on transmission rather than distribution, ISA Cteep shares Light's regulated-utility revenue model, capex-intensive infrastructure profile, and Brazilian regulatory exposure to ANEEL.
