History The company was founded in 1899 as The American Rolling Mill Company (ARMCO) in Middletown, Ohio, where it operated a production facility. George Matthew Verity (1865–1942) was a founder and its first president. In 1922, it opened a second production facility, Ashland Works in Ashland, Kentucky. In 1971, Armco Steel purchased Kansas City-based engineering firm Burns & McDonnell; however, in 1985, employees of Burns & McDonnell secured a loan to buy the company from Armco. In 1978, Armco Steel was renamed Armco, Inc. It moved its headquarters to New Jersey in 1985. In 1982, a recession threatened the U.S. steel industry. Several of the nation’s steel companies reported losses for the first half of the year, while other companies, like Armco, were barely breaking even. In 1989, it entered into a limited partnership with Kawasaki Steel Corporation, which contributed several of its production facilities to the company. While the company achieved over $1 billion in annual sales in the early 1990s, it was not profitable. The company then hired the 65 year old Tom Graham and Richard M. Wardrop, Jr. to improve its finances. These
