For the second time in a week, Canadian drug maker Valeant Pharmaceuticals has raised its offer to acquire Botox maker Allergan Inc.
The revised offer issued Friday now lifts the proposed deal value to about $53 billion, up from Wednesday's bid of $50 billion. Valeant's original bid last month was for $46 billion, which Allergan called too low.
A spokeswoman for Irvine company did not immediately respond to a request for comment on the latest bid.
Under the terms of the most recent cash-and-stock proposal, Valeant Pharmaceuticals International Inc. said it would pay $72 a share and 0.83 of Valeant stock for the Southern California company. The cash offer is $23.70 higher than the original bid issued April 22.
Valeant retained a provision from its second offer related to future sales of a medication to treat an eye condition. The Canadian company would pay Allergan shareholders up to $25 a share based on a sales target of Darpin, a medication in early stages of development. The company said it would invest up to $400 million and retain Allergan employees to develop the drug.
"We believe our revised offer provides enormous value to both Valeant and Allergan shareholders," said J. Michael Pearson, Valeant's chief executive. "We are very committed to getting this deal done, and are now modifying our offer with the assistance of Pershing Square to increase the economics for all Allergan shareholders."
Shares for both companies closed higher Friday. Valeant shares were up $1.99, or 1.5%, to $131.21. Allergan shares were up $8.96, or 5.7%, to $167.46.
Valeant recently teamed up with activist investor Bill Ackman in an attempt to take over Allergan.
The back-and-forth is being carefully watched by Allergan's 11,600 employees. Analysts have predicted that hundreds or thousands could be out of jobs if the deal goes through and Valeant slashes research and development funding as previously proposed.
The merger, if it goes through, would double the size of Valeant. It would become one of the largest specialty pharmaceutical companies in the world -- and a giant in the eye care and skin care business.
