After months of eyeing possible acquisition targets, Canada’s Valeant Pharmaceuticals International decided to narrow its sights on Bausch & Lomb.

Laval, Quebec–based Valeant said Monday that it has agreed to acquire the contact lens maker in a cash deal worth $8.7 billion. The transaction’s terms call for Valeant to pay $4.5 billion to a group of Bausch & Lomb investors led by private equity firm Warburg Pincus, with the remaining $4.2 billion earmarked to pay off the target’s debt.
