On Monday, the chief executive of Dutch health technology company Philips blamed "chips and ships" as it cut its financial outlook with a shortage of electronic components and a lack of shipping containers hampering production and delivery.
Shares in Belgium's Umicore also fell after the catalytic converter maker cut its 2021 core profit outlook due to the chip shortages.
Analysts at Jefferies, meanwhile, point to the risks stemming from staff shortages and the possible need to increase wages at a wide range of European companies, from Fresenius Medical Care to game video editor Ubisoft and the UK's Royal Mail.
