In 2021 this company reached a US$1.2 billion settlement with investors who saw the company's stock price plummet from more than $250 a share in 2015 to below $10 two years later. The investors alleged that the securities were artificially inflated due to the concealment of Valeant's "unsustainable and deceptive" price gouging practices wherein Valeant acquired pre-existing drugs, some of them life-saving medicines, and then dramatically raised prices to boost short-term profitability. The settlement is the largest securities class action settlement ever against a US pharmaceutical manufacturer.
