Ventling brings vast experience and expertise in corporate finance to the Perspecta board. He retired from Ernst & Young LLP (EY) in 2015 after serving more than 31 years in both client serving and executive leadership roles.

"Mike brings an extensive background in accounting, auditing and transactions. His demonstrated experience driving shareholder value and highly relevant board and audit committee experience make him an invaluable addition to our board.”

From 2006 to 2010, Ventling was EY’s vice chair and managing partner for the Americas geographic area, running a $700 million U.S.-based business unit. Prior to that role, he held various executive positions in general management, quality and risk management on a national and global scale. During his initial 20 years with EY, Ventling gained experience in audit, tax and transaction advisory services.

Ventling has prior public company board and audit committee experience at CSRA Inc., from 2015 until it was sold to General Dynamics in April 2018.

In addition, the company announced today that Biggs C. Porter resigned from the board effective October 9, 2018 to return to full-time employment.
