Pfizer to buy Allergan in Biggest Drug Merger

On Monday, Pfizer and Botox-maker Allergan announced the two companies have entered into a definitive merger agreement worth $160 billion. “The proposed combination of Pfizer and Allergan will create a leading global pharmaceutical company with the strength to research, discover and deliver more medicines and therapies to more people around the world,” says Ian Read, chairman and CEO of Pfizer. “Allergan’s businesses align with and enhance Pfizer’s businesses, creating best-in-class, sustainable, innovative and established businesses that are poised for growth. Through this combination, Pfizer will have greater financial flexibility that will facilitate our continued discovery and development of new innovative medicines for patients, direct return of capital to shareholders, and continued investment in the United States, while also enabling our pursuit of business development opportunities on a more competitive footing within our industry.”

The acquisition, which would create the world's largest drugmaker and shift Pfizer's headquarters to Ireland, would also be the biggest-ever instance of a U.S. company re-incorporating overseas to lower its taxes. Under the terms of the proposed transaction, the businesses of Pfizer and Allergan will be combined under Allergan plc, which will be renamed “Pfizer plc.” The companies expect that shares of the combined company will be listed on the New York Stock Exchange and trade under the “PFE” ticker. Upon the closing of the transaction, the combined company is expected to maintain Allergan’s Irish legal domicile. Pfizer plc will have its global operational headquarters in New York and its principal executive offices in Ireland. “The combination of Allergan and Pfizer is a highly strategic, value-enhancing transaction that brings together two biopharma powerhouses to change lives for the better,” says Brent Saunders, CEO of Allergan. “This bold action is the next chapter in the successful transformation of Allergan allowing us to operate with greater resources at a much bigger scale. Joining forces with Pfizer matches our leading products in seven high growth therapeutic areas and our robust R&D pipeline with Pfizer’s leading innovative and established businesses, vast global footprint and strength in discovery and development research to create a new biopharma leader.” The deal enhances offerings from both Pfizer's faster-growing branded products business, with additions like Botox, and its older established products unit.
