Oct 8 (Reuters) - Shares in Seven & i Holdings ( SVNDF )

surged 9.5% in morning trading on Wednesday after Bloomberg News

reported Alimentation Couche-Tard ( ANCTF ) upped its acquisition

price offer to $18.19 per share.

The new bid would value the Japanese retailer at 7 trillion

Yen ($47.27 billion) and is 20% higher than Couche-Tard's

previous offer, Bloomberg said, citing people with knowledge of

the matter.

The operator of the 7-Eleven convenience store chain

rejected the original offer last month saying it "grossly

undervalues" its business.
