One of the billionaire heirs behind French drugmaker Ipsen SA has left his $4 billion fortune to a Luxembourg charity and an offshore trust, clouding the outlook for the company’s long-term control and ownership.
The succession plan of Henri Beaufour, a grandson of the firm’s founder who died childless last year at the age of 60, began taking effect earlier this month, according to corporate filings. His holding was transferred to a foundation and new governance structure.
