President Jair Bolsonaro announced the 71-year-old Luna would take the helm of Petroleo Brasileiro SA, as the firm is formally known, in a Facebook post in February.
Petrobras shares fell sharply when Luna's predecessor, Roberto Castello Branco, was forced out after the group hiked domestic fuel prices several times in February, angering Bolsonaro.
Petrobras also said in a securities filing that minority shareholders proposed a new candidate for the board, banker Jose Joao Abdalla Filho, owner of Banco Classico and energy and agribusiness companies. His name was proposed by investment funds holding Petrobras shares.
In a securities filing, Petrobras said it asked the ministry about information that "should have been released to the market." The ministry has yet to respond, Petrobras said.
Bolsonaro's remarks on Wednesday helped wipe out gains in Petrobras' preferred and ordinary shares and they closed that session virtually flat. The preferred shares closed 0.08% down. The selling continued on Thursday.
Shares in Petroleo Brasileiro SA, as the company is officially known, plunged 22% on Monday, wiping out 71 billion reais ($13 billion) in market value.
The decline in 1P reserves was mainly caused by the 32% price drop in hydrocarbon prices, Ecopetrol said.
The Brent price used for valuation in 2020 was $43 per barrel, compared with $63 per barrel in 2019, implying a decrease of 215 million boe, the company said.
ANP said aviation gasoline produced by Petroleo Brasileiro SA in January did not meet required standards and that its auditors have been at the Presidente Bernardes refinery investigating the issue since Feb. 3
We all agree that the recovery is fragile, there are still more uncertainties, but we are cautiously optimistic that the recovery will materialise this year.
This year the way we see it is a year of recovery, whether it's going to be the end of the year where we are supposed to reach the balance or the beginning of 2022.
Branco said in the Wednesday edition of daily Valor Econômico that the claims amount to a personal "professional offense" against him and the government's economic policymakers.
As graduated economists ... we learned over 40 years ago that price controls are part of a museum of ineffective weapons to fight inflation.
