Discussions between Atos SE (ENXTPA:ATO) and Czech billionaire Daniel Kretinsky's EP Equity Investment S.à r.l. around the sale of the struggling French company's legacy IT services business have hit a roadblock, according to people familiar with the matter. Atos Chairman Jean-Pierre Mustier was due to meet the Czech billionaire the second week of January, but has been postponing the meeting since then, the people said, asking not to be named discussing private information.
