Horizon Pharma to Buy Raptor Pharmaceutical for $800 Million

San Diego – September 15, 2016 – Cooley advised Horizon Pharma on its agreement to acquire Raptor Pharmaceutical for approximately $800 million. The transaction is expected to close in the fourth quarter.

“The proposed acquisition of Raptor furthers our commitment to helping people with rare diseases and is a significant step in advancing our strategy to expand our rare disease business,” said Timothy P Walbert, chairman, president and CEO of Horizon.

Horizon, headquartered in Dublin, Ireland, is a specialty biopharmaceutical company focused on improving patients' lives by identifying, developing, acquiring and commercializing differentiated products that address unmet medical needs. The company markets a portfolio of products in arthritis, inflammation and orphan diseases.

Cooley has a longstanding relationship with Horizon, including taking the company public in 2011.
