Transmissora Aliança de Energia Elétrica S.A

What it is

Taesa has been listed on Brazil’s B3 exchange since 2006, trading at the Level 2 corporate-governance standard, with units under the ticker TAEE11. It operates 43 government-issued concessions regulated by Brazil’s energy regulator ANEEL, and is the largest private player in the sector measured by the regulated annual revenue it is permitted to earn.

The business model is simple and durable: Taesa builds and maintains high-voltage power lines; in return, the government guarantees a fixed annual fee — the “permitted revenue” — for the life of each concession, regardless of how much electricity actually flows. Those concessions have a weighted average remaining life of 15.2 years.

Who owns it

The two controlling shareholders are Companhia Energética de Minas Gerais (CEMIG), the Minas Gerais state utility, and ISA Investimentos e Participações do Brasil (ISA Investimentos), the Brazilian arm of Colombian transmission giant ISA; together they hold 63% of the voting interest under a formal shareholders’ agreement. CEMIG holds roughly 21.7% of the total capital, and ISA holds roughly 14.9%.

Individual retail investors, spread across Brazil’s stock exchange, account for about 61% of the free float. The remaining institutional slice — about 26% of shares — is held by funds and asset managers, per EODHD data.

Who runs it

Rinaldo Pecchio Jr. has been CEO since August 2024.

He previously served as Taesa’s own CFO and investor-relations director from May 2023 to February 2025, and held the CEO role on an interim basis from February 2024 before being confirmed permanently.

Catia Cristina Teixeira Pereira became CFO and investor-relations director in February 2025. She came directly from SABESP, the São Paulo state water company, where she had served as CFO since March 2023.

The money, in plain words

Revenue grew 10.6% in 2024 and then 24.4% in 2025 (our calculation), reaching R$4.62bn (~US$897m) — the acceleration driven partly by new lines entering service and partly by inflation-linked contract resets. Taesa keeps R$0.34 (US$0.07)of every real it earns as net profit — a net margin of 34.2% (our calculation) — which is high even for a regulated utility.

For every real shareholders have invested in the company, it earns back about R$0.21 (US$0.04)a year — a return on equity of 20.8% (our calculation), comfortably above the cost of capital in Brazil. The stock trades at 39.3 times earnings, a premium that reflects the predictable, bond-like cash flows investors are willing to pay up for.

The one genuine counterweight is debt: Taesa carries R$10.2bn (~US$1.99bn) in net debt (our calculation), roughly 6.5× its annual net profit. That is normal for an infrastructure company with long, guaranteed concession revenues, but it means rising interest rates in Brazil squeeze the bottom line more than they would for a cash-rich business.

The dividend yield of 8.7% remains one of the highest in the Brazilian utilities sector, reflecting a policy of distributing the great majority of available cash to shareholders.

What it is doing now

The most recent material move is a deal signed in May 2026: Taesa agreed to buy five transmission companies from Energisa for R$1.545bn (~US$300m), at a total enterprise value of R$2.293bn (~US$445m). The assets are located in the states of Tocantins, Pará, and Goiás — all strategic corridors for Brazil’s fast-growing renewable energy build-out in the north and centre-west of the country.

In April 2026, Taesa’s annual general meeting approved the full-year 2025 profit distribution of approximately R$1.12bn (US$217 mn) in dividends, with R$810.9m (US$157 mn) already paid out at R$2.35 (US$0.46)per TAEE11 unit.

What to watch

• CEMIG exit: Brazil’s press has reported CEMIG evaluating a sale of its ~21.7% stake; any such transaction would almost certainly trigger a change-of-control clause and an offer to minority investors, making ownership the single most consequential variable for the share price.
• Interest-rate sensitivity: With net debt of R$10.2bn (US$2.0 bn), every meaningful move in Brazilian benchmark rates affects refinancing costs and, in turn, the dividend Taesa can afford to pay.
• Concession pipeline: New ANEEL auctions add to permitted revenues but also add capital expenditure; how disciplined Taesa is with auction pricing will determine whether returns stay at current levels or dilute.
• Energisa deal close: Regulatory approval from ANEEL for the five newly acquired assets will be watched for timing and any conditions attached.
