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.

Ireland’s Mallinckrodt will buy U.S. drugmaker Endo in a cash-and-stock deal valued at $6.7 billion. The companies said Thursday that Endo shareholders will receive a total of $80 million in cash and own nearly 50% of the combined company. Mallinckrodt shareholders will have a stake of slightly more than 50%.
