Pfizer and Allergan speed up $150bn mega-merger talks

By: Sarah Spickernell

Pfizer has hastened discussions with Allergan over a potential acquisition, according to reports.

Ireland-base Allergan confirmed at the end of last month it was in talks to join forces with its US rival, but according to a source close to the matter the decision making process has picked up pace.

Pfizer is said to be negotiating an offer of between $370 and $380 per Allergan share, valuing the company at $150bn. However, the source added a deal was far from certain following news that the US Treasury plans to tighten its tax evasion rules further. Both Allergan and Pfizer declined to comment.

Pfizer is currently headquartered in the US, but being domiciled in Ireland would allow it to avoid paying a large amount of US corporation tax.

If the deal goes ahead, the resulting company would be the largest drugs firm in the world with a market capitalisation of $300bn (£196bn). This would put it ahead of Johnson & Johnson, which has a value of $277bn.

From Allergan's point of view, Pfizer is in a good position in terms of growth. In October, it reported a six per cent increase in revenue to $12.2bn in the third quarter, and improved its full-year outlook on the back of this.

Shares in Allergan, which like Pfizer is listed on the New York Stock exchange, declined 1.33 per cent in pre-market trading in light of the rumours. Pfizer shares fluctuated slightly above and below last night's closing figure.
