AB Volvo expects its first-quarter operating income to take a hit from uncertainty caused by the Russia-Ukraine war.

It will set aside provisions worth 4 billion crowns ($423.2m) to cover that, the Swedish truck maker said today.

Russia's six-week long incursion in Ukraine has seen more than 4 million people flee abroad, killed or injured thousands, turned cities into rubble and led to sweeping sanctions on its leaders and companies.

"The Volvo Group has total assets of about 9 billion crowns related to Russia, of which about 6 billion crowns is cash items that could be materialised over the coming years," it said in a statement.

"In the first quarter 2022, assets amounting to approximately 4 billion crowns will be provided for and have a negative impact on operating income, primarily in the Financial Services segment," it added.

Volvo in February suspended all sales, service and production in Russia, which last year accounted for about 3% of its net group sales of about 372.2 billion crowns.

The company's production site in Kaluga, near Moscow, has a capacity to produce 15,000 vehicles per year and employed over 600 people.

Shares in the company have lost a quarter of their value since the start of the year as shortages of components and freight capacity led to production disruptions and increased costs, denting profits
