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.

The new entity will be listed on the New York Stock Exchange and is expected to generate pro forma revenue of $3.6 billion in 2025 and at least $150 million of annual operating synergies by year three.

Mallinckrodt and Endo are merging in a cash and stock deal worth some $6.7 billion, the companies said Thursday. Under the agreement, Endo shareholders are slated to receive a total of $80 million in cash and own 49.9% of the combined company, while Mallinckrodt shareholders will have a 50.1% piece of the pie.
