Drugmaker Perrigo won’t confirm whether its CEO will take the top job at troubled Valeant Pharmaceuticals.

The Wall Street Journal has reported that Valeant is finalizing a contract with Perrigo Chairman and CEO Joseph Papa and could announce the hire this week. Perrigo said it would not comment on “speculation or market rumor.” Valeant is under scrutiny for its strategy of buying small drugmakers, then raising prices sharply on older, offpatent drugs. In March, Valeant said it would replace CEO Michael Pearson after billions evaporated from the company’s worth.
