The firm, which advised on the Jersey aspects of the deal, say that the deal is the largest ever foreign takeover by a Japanese company.
Their work, which involved working alongside lead bidder counsel Linklaters, resulted in a scheme that became effective on 8 January. It was passed through the Jersey’s Royal Court, and is believed to be the highest value scheme to have come before it.
Mr Dinning said the firm was “delighted” to have acted for Takeda alongside Linklaters on what he described as a “very significant transaction”.
Mourant were also involved in the deal, advising Shire, a client they have advised for over 10 years.
