South African power company Eskom Holdings has shortlisted three candidates for chief executive officer to lead the loss-making utility out of its debt crisis, according to three people familiar with the process. Andy Calitz, who started his career as an electrical engineer at Eskom, made the cut, according to two of the people who declined to be identified because the information isn’t public. Another is former CEO Jacob Maroga, one of the people said. They didn’t identify the third person on the list.
