SAO PAULO/RIO DE JANEIRO - Brazilian state-run oil giant Petrobras on Thursday posted a net loss of 2.6 billion reais ($470 million) for the second quarter of 2024, the firm said as it announced lower-than-expected results and a reduction in investment estimates.

Despite the results, the firm's board approved a 13.57 billion-real ($2.45 billion) payout to shareholders in dividends and interest on equity, equivalent to 1.05 reais per share.

The payout will be made using 6.4 billion reais out of funds from 2023 extraordinary dividends that were withheld by the board in March, Petrobras said in a securities filing, leaving the fund with around 15.5 billion reais.

The net loss - the firm's first since the third quarter of 2020 - was a result of a one-off 11.9 billion reais tax charge and the devaluation of the real, among other non-recurring items, said the firm.

The tax payments should help the Brazilian government to balance its budget as the administration of President Luiz Inacio Lula da Silva seeks new sources of revenue to meet its fiscal targets for this year and 2025.

This is the first quarter under new Petrobras Chief Executive Magda Chambriard, who was put in charge by Lula with the mission to speed up investments, in order to boost Brazil's economy and generate local jobs.

The company's net recurring profit fell 46.5% in the second quarter to 15.7 billion reais, missing analysts' expectations of 22.3 billion reais, according to LSEG data.

Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) fell 12.3% in the period, to 49.7 billion reais, below an LSEG poll estimate of 63.3 billion reais.

Petrobras also lowered its planned investments for this year to between $13.5 billion and $14.5 billion, from a planned $18.5 billion for 2024.

Its new forecasts include an estimated $11.1 billion to $12.1 billion earmarked for the exploration and production segment. The fresh forecast will not impact its oil and gas production curve, the firm said.

Despite the lower-than-expected financial results, the firm's net revenue showed an increase of 7.4%, to 122.26 billion reais.
