Medtronic, listed on the New York Stock Exchange, could announce as soon as today a stock and cash deal worth between $45bn (£26.5bn) and $50bn to takeover the Dublin-based company, the latest in a bout of pharmaceutical mergers.
The outfit, which had been considering a bid for UK rival Smith & Nephew, is thought to be pursuing the deal to take advantage of Ireland’s lower tax rates.
The deal, first reported by the Wall Street Journal, is set to surpass UK firm Zeneca’s $31.8bn acquisition of Swedish firm Astra in 1998, the largest cross border M&A pharma deal on record, according to data at Thomson Reuters.

Ireland has a 12.5 per cent tax rate while the UK rate is set to fall to 20 per cent. America has a tax rate of 35 per cent.
