Martin Marietta taps insider as finance chief

Building material supplier Martin Marietta MLM on Tuesday appointed insider Michael Petro as its chief financial officer, effective immediately.

He replaces James Nickolas, who stepped down in April after nearly eight years with the company.

Petro, who joined the company in 2015, was most recently its senior vice president of strategy and development.

Raleigh, North Carolina-based Martin Marietta is a supplier of building materials and makes ready-mixed concrete and asphalt.

The company also said Robert Cardin, who has been serving as interim CFO since April, will continue in his role as senior vice president, controller, and chief accounting officer.
