William O’Brien, president of BATS Global Markets, has left the company.
No reason was given for his departure. Joe Ratterman, CEO of BATS Global Markets, added the title of president, the company announced Tuesday.
Mr. O’Brien was named president of BATS on Jan. 31 when BATS’ merger with stock exchange operator Direct Edge closed. Mr. O’Brien had been CEO of Direct Edge.
Mr. Ratterman had been president and CEO of BATS before the merger.
In a letter to clients dated Tuesday and obtained by Pensions & Investments, Mr. Ratterman wrote: “BATS Global Markets remains a strong, stable company that is committed to its long-term mission of making markets better. We believe we have the global team in place to continue to realize this vision while helping all of our customers to achieve their business objectives.”
Randy Williams, BATS spokesman, said the company would not comment further.
