The Swedish carmaker, founded by China's Geely and Volvo Cars, posted an operating loss of $196.4 million, down from $292.9 million a year ago, while revenue rose to $435.4 million from $212.9 million.

Polestar, which listed on the Nasdaq exchange in June via a merger with a special-purpose acquisition company (SPAC), said rising costs for raw materials used to make its batteries had not yet fully hit because of set contracts.

Chief Financial Officer Johan Malmqvist told Reuters Polestar would face higher costs in the fourth quarter, while price increases for its cars this summer had been slow to kick in.

"The full extent of that will then... partly offset the raw material costs," he said, adding that the carmaker expected to raise prices further.

Malmqvist said because much of Polestar's cost base is in China, unfavourable exchange rates hit the company in the third quarter and will continue in the fourth.

Supply chain bottlenecks, including a global semiconductor shortage, have made it increasingly difficult for carmakers to meet targets.

But Chief Executive Thomas Ingenlath said Polestar was on track to deliver 50,000 cars in 2022.

The company delivered 9,215 vehicles in the third quarter, while deliveries for the first nine months of 2022 rose 100% to about 30,400 cars.

Ingenlath said the remaining 20,000 cars needed to meet its target have been produced.

"We are now in a fairly comfortable position of 'only' having to deliver these cars and not worry anymore about the production", the CEO said.
