Martin Marietta Materials Inc

A building-materials maker whose crushed stone, sand, gravel, and cement go into highways, homes, and airports across the U.S., Canada, and the Bahamas. Its name traces to a 1961 merger between aerospace pioneer Glenn L. Martin and the American-Marietta Corporation, while its quarries trace back to a 1939 stone company founded by two brothers in Raleigh, North Carolina. The company was spun off in the 1990s from the aerospace giant that later became Lockheed Martin.
