In the longer term, the consumer goods giant has also set out to grow its underlying revenue by 3%-5%, keeping profits ahead of sales growth and achieving savings of €2bn.
Restructuring is estimated to cost around €1bn for 2021 and 2022 and lower thereafter, the group said.

The company ended the year with €20.9bn of net debt including €5.5bn of cash and cash equivalents.

China has normalised in many categories, while economic activity in India picked up particularly in the final quarter, the group said.

“Fundamentally Unilever’s ability to keep thriving despite operating in a highly competitive marketplace is down to the strength of its brands, distribution power and marketing expertise."
“Achieving a target of underlying sales progression of 3% to 5% a year will take hard work and the shape of the business is likely to keep changing as it focuses on more prosperous areas. That means a mixture of acquisitions and disposals in the coming years.”
