Mallinckrodt and Endo, drugmakers which recently emerged from bankruptcy after a wave of U.S. opioid lawsuits, announced plans Thursday to join forces in a deal valued at $6.7 billion. Mallinckrodt Chief Executive Siggi Olafsson said the companies' operations and products complement each other.

Dublin-headquartered Mallinckrodt is taking over smaller rival Endo and planning to list the combined firm on the New York Stock Exchange, the two drugmakers said Thursday.

As per the Thursday release, Endo will be folded into Mallinckrodt, which will then continue as the holding entity for the combined companies. Post-merger, the company will be listed on the New York Stock Exchange and is projected to generate around $3.6 billion in revenue this year.
