Equifax CEO Richard Smith will testify about a massive data breach that impacted up to 143 Americans to the Senate Banking Committee on October 4.

The company's shares have plummeted more than 30 percent amid letters from members of Congress about the hack and requests for answers. Smith had already agreed to testify before a U.S. House panel on October 3.
