Afluente Transmissão de Energia Elétrica S.A

What it is

Afluente Transmissão plans, builds, and operates electric power transmission lines, substations, and control centres in Brazil, running seven substations across the state of Bahia — Tomba, Funil, Brumado II, Itagibá, Ford, Pólo, and Camaçari — with an installed capacity of 600 MVA and 489.1 kilometres of transmission line.

Transmission is one of the more predictable corners of energy: revenue is set by Brazil’s electricity regulator (ANEEL) under a formula called the Annual Permitted Revenue (RAP), which is periodically adjusted and does not depend on how much electricity consumers actually use, only on whether the lines are available.

Who owns it

Afluente sits inside the portfolio of Neoenergia, one of the largest electricity holding companies in Brazil, which holds approximately 87.84% of its shares. The structured data shows insiders controlling 98.675% of the total share count, meaning the free float available to outside investors is roughly 1.3% — wafer-thin (our calculation).

Afluente T was born in 2009 from a corporate split within the Neoenergia group, when the transmission assets were carved out of Afluente Geração e Transmissão de Energia Elétrica, itself created to take on the power-line assets previously held by Coelba, the Bahia state electricity distributor that Neoenergia also controlled. Neoenergia is in turn majority-owned by Spanish energy giant Iberdrola.

Who runs it

The board of Afluente is chaired by Eduardo Capelastegui Saiz, who has served as a board member of Neoenergia since June 2022 and as its chief executive since July 2022, and previously spent sixteen years overseeing Iberdrola’s South American assets.

Shares have traded on B3 under the code AFLT3 since 25 October 2010, with the company registered at CVM under code 22179. Because Afluente is run as a tightly held subsidiary, day-to-day management is integrated into Neoenergia’s operational structure; a separately named chief executive for Afluente itself is not disclosed in available sources.

The money, in plain words

Afluente earns more than 51 cents of net profit from every real of regulated revenue — a net margin of 51.4% — which is exceptional even by the standards of regulated utilities, where margins above 20% are already considered strong. For every real shareholders have put in, the company earns about 12.7 back each year — a return on equity of 12.7%, solid for an asset-heavy regulated business (all figures: EODHD structured data).

Full-year 2024 revenue was R$86.0m (US$17 mn) (~$16.5m), producing net profit of R$34.0m (US$7 mn) (~$6.5m); by fiscal 2025 revenue had fallen to R$49.2m (US$9 mn) (~$9.4m) and net profit to R$23.8m (US$5 mn) (~$4.6m) — a 42.8% revenue decline year-on-year (our calculation), likely reflecting a RAP tariff reset cycle rather than a loss of physical assets. The balance sheet carries essentially no financial debt and almost no cash (R$2,000 (US$384)on hand per the latest filing), with equity of R$247.3m (US$48 mn) (~$47.5m) against total assets of R$343.7m (US$66 mn) (~$66.0m) (our calculation from EODHD balance data).

What it is doing now

As recently as June 2026, the board convened a meeting and issued a shareholder notice, with filings recorded on B3 on 19 June 2026 — consistent with a normal distribution of interest on equity to shareholders.

Neoenergia, as controlling parent, has invested in a new Asset Monitoring Centre (CMAT) in Campinas, São Paulo, opened in March 2025, aimed at improving efficiency and reliability across its transmission portfolio, which includes Afluente.

What to watch

• RAP reset cycle. The 42.8% revenue drop in fiscal 2025 versus 2024 is the dominant financial risk; investors need to track ANEEL’s next tariff review to know when — and by how much — permitted revenue recovers (our calculation).
• Liquidity. The near-zero free float and very low trading volume are critical factors for any investor who may need to exit a position quickly.
• Parent strategy. Neoenergia has shown an active strategy of asset rotation and modernisation across its transmission holdings — any decision to consolidate or delist Afluente would reshape the minority investment case entirely.
• Iberdrola link. Afluente’s fate ultimately follows Iberdrola’s capital-allocation decisions for Latin America; any strategic shift at the Spanish parent ripples straight down to this small listed subsidiary.
