Shares in Marmite maker Unilever have slumped by 8% after US rival Kraft Heinz abandoned its £115bn offer to swallow up the consumer goods giant.
The deal proposed by the American maker of Heinz ketchup and Philadelphia cheese would have brought together some of the world’s best-known brands.
Shares in Anglo-Dutch group Unilever – which also makes Persil, Dove soap and PG Tips – had surged on Friday when details of the approach first emerged.
It would have been the biggest ever acquisition of a UK-listed company.
But Unilever immediately rejected the offer, saying it “fundamentally undervalues” the company.
It had been forced to disclose the offer publicly at an earlier stage than planned after rumours circulated among traders.
Heinz purchased Kraft in a previous mega-deal in 2015.
Kraft’s previous takeover of Cadbury’s in 2010 attracted controversy when it reneged on a pledge to keep open a plant near Bristol, resulting in hundreds of job losses.
That division of the US giant has since been spun off as a separate company, Mondelez.
Kraft Heinz is controlled by billionaire US investor Warren Buffett and Brazilian investment firm 3G Capital.
George Salmon, equity analyst at Hargreaves Landsdown, said: “The deal going through was far from a formality.
“However, it is still surprising to see it shelved just one business day after the initial news broke.
“The deal was set to top £100bn, so the size premium would always have been a consideration – especially since Warren Buffett, one of the biggest names behind the bid, hardly has a reputation for paying anything other than the price he sees fit.”
