Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) slipped 36% to 3.197 billion reais.
Net operating revenue reached 8.033 billion reais, down 13%.
The earnings results were mainly hit by a reduction of 1.941 billion reais in transmission revenues, which are readjusted
by inflation indexes, the company said.
Eletrobras is going through a major overhaul after the Brazilian government privatized its largest utility through a $6.5 billion public offering. Last month, the firm offered voluntary layoffs to over 2,000 people, or about 22% of its workforce.
