Renault reported an 8 billion euro ($9.7 billion) loss for 2020 which, combined with gloomy take on the market, sent its shares down more than 5% in late morning trading.

"We are in the midst of a battle to try to manage a difficult year in terms of supply chains, of components," Chief Executive Luca de Meo told reporters. "This is all the collateral damage of the Covid pandemic... we will have a fairly volatile year."

De Meo, who took over last July, is looking at ways to boost profitability and sales at Renault while pushing ahead with cost cuts. There were early signs of improving momentum as margins inched up in the second half of 2020.

The group gave no financial guidance for this year, although it said it might reach a target of achieving 2 billion euros in costs cuts by 2023 ahead of time, possibly by December.

Executives said they were confident the carmaker could be profitable in the second half of 2021, but that they lacked sufficient market visibility to provide a forecast.

Renault struck a cautious note, saying it was focused on its recovery but warned orders had faltered in early 2021 as pandemic restrictions continued in some countries.

The group is facing new challenges as the European Union tightens emissions regulations and after rivals PSA and Fiat Chrysler joined forces to create Stellantis, the world's fourth-biggest automaker.

The auto industry endured a tough 2020 but a swift rebound in premium car sales in China helped companies such as Volkswagen and Daimler to weather the storm.

Auto companies globally have since been hit by a shortage of semiconductors that has forced production cuts worldwide.

"The beginning of the year has shown some signs of weakness," De Meo told analysts, but added the chip shortage should be resolved by the second half of 2021. "We have taken the necessary measures to anticipate and overcome challenges."

Renault estimated the chip shortage could reduce its production by about 100,000 vehicles this year.

SHARP HIT

The group was already loss-making in 2019, but took a sharp hit in 2020 during lockdowns to fight the pandemic, which also hurt its Japanese partner Nissan.

Analysts polled by Refinitiv had expected a 7.4 billion euro loss for 2020. The group posted negative free cash flow for 2020.

The 2018 arrest of Carlos Ghosn, who formerly lead the alliance between Renault and Nissan, plunged the automakers into turmoil.

In a further sign that the companies have been working to repair the alliance, De Meo told journalists that Renault and Nissan will announce new joint products together in the coming weeks or months.

Renault has begun to raise prices on some car models, and group operating profit, which was negative for 2020 as a whole, improved in the last six months of the year, reaching 866 million euros or 3.5% of revenue.

Analysts at Jefferies said the operating performance was better than expected. Sales were still falling in the second half, but less sharply.

Renault is slashing jobs and trimming its range of cars, allowing it to slice spending in areas like research and development as it focuses on redressing its finances. It is also pivoting more towards electric cars as part of its revamp.

It was already struggling more than some rivals with sliding sales before the pandemic, after years of a vast expansion drive it is now trying to rein in, focusing on profitable markets.

De Meo told journalists on Friday that the French carmaker will make three new higher-margin models at its Palencia plant in Spain, where manufacturing costs are lower, between 2022 and 2024.
