The group has hiked its provision for the recall by 45% to €725m

The Dutch health technology group warned supply chain woes would hit profits and that a ventilator recall needed to be expanded.

Shares in Philips plunged 15%, its worst intra-day drop in over 20 years, after the Dutch health technology group warned supply chain woes would hit profits and a ventilator recall needed to be expanded.

Philips recalled up to 4m of its breathing-aid machines last year amid concerns that a type of foam used in the devices could degrade and become toxic.
