An Ogier team led by partners Simon Dinning and Nick Williams has advised Japan's Takeda Pharmaceutical on its £46 billion (over £63 billion including Shire's debt) acquisition of Shire, creating one of the world's largest pharmaceutical firms.
The deal is the largest ever foreign takeover by a Japanese company.
The Ogier team advised on the Jersey law aspects of the deal, which was effected by way of the scheme of arrangement in Jersey, the highest value scheme to pass before the Royal Court in Jersey.
The scheme became effective on 8 January 2019.
Ogier worked alongside lead bidder counsel Linklaters on the deal.
Simon Dinning was supported by senior associate Kevin Grové. Nick Williams (head of Dispute Resolution in Jersey) was assisted by senior associate James Angus.
Simon said: "We were delighted to have been involved in acting for Takeda, with Linklaters, on this very significant transaction.
"We have seen an increasing use of Jersey schemes of arrangement for very large international M&A transactions. We have a leading position in this market and can blend our offshore and onshore experience in this area."
