Richard Smith, CEO and chairman of Equifax, abruptly retired Tuesday following a data breach at the credit-reporting service that affected the personal information of 143 million people.
Equifax shares traded up 0.8 percent Tuesday afternoon. They have fallen 26 percent in September after the company revealed the breach.
The announcement was made Tuesday by Mark Feidler, a current board member, who will serve as nonexecutive chairman. Paulino do Rego Barros Jr., president of company's Asia Pacific region, has been appointed as interim CEO.
Smith, who was 57 as of the company's proxy statement in March, became CEO and chairman in 2005 after 22 years at General Electric in senior roles in various divisions. He is to appear at a hearing of the Senate Banking Committee on Oct. 4 and is the only person scheduled to testify. He is also scheduled to testify next week at a hearing of the House Energy and Commerce Committee.
