Multinational French labs group Eurofins saw its share price lose almost a quarter of its value on Monday after US investigative research and investment firm Muddy Waters released a report highlighting numerous “oddities and contradictions” which it believes suggest the group is “optimised for malfeasance”. The share price regained most of its lost value after Eurofins published a rebuttal which addressed some of the issues raised in the report. However questions still remain, most pertinently over allegations that the firm’s CEO and founder, Gilles Martin, has been using real estate to “siphon” off money from the company.
