Valeant Pharmaceuticals International's ailing chief executive, Michael Pearson, said he was on the road to recovery but was uncertain about when he would return from medical leave.
Pearson, who joined Valeant as CEO in 2010 after a 23-year career at consultancy McKinsey & Co., was hospitalized with severe pneumonia in late December.
"As you know, I unexpectedly entered the hospital in late December to receive treatment for severe pneumonia and some unexpected complications resulted in a longer hospital stay than anticipated," Pearson said in a memo to employees on Monday. "...I look forward to being back at work when able," he said.
Pearson's illness capped a tumultuous year for Valeant as investors turn up the pressure for the Canadian drugmaker to provide a more detailed plan on how it will increase profits in 2016.
