Company history
ABM traces its origins to 1909, when Morris Rosenberg started a one-person window-washing business in San Francisco. The business adopted the name American Building Maintenance Company in 1913 and expanded to Los Angeles, Portland, and Seattle by 1920. It listed on the American Stock Exchange in 1965 and the New York Stock Exchange in 1972.[20] In 1985, the company incorporated in Delaware as American Building Maintenance Industries, Inc.; it changed its name to ABM Industries Incorporated in 1994.[1]
In the early 2000s, acquisitions including OneSource and Linc Group expanded ABM’s janitorial and technical facility-services operations; the Air Serv acquisition established aviation as an industry group.[21] Scott Salmirs became president and CEO in 2015.[22][23] ABM acquired GCA Services Group in 2017, strengthening its education-market presence, followed by Able in 2021, which expanded its facilities and energy-efficiency capabilities, and RavenVolt in 2022, adding microgrid systems to its technical-solutions business.[24][25][26][27][28][29][30] [20][1][21][22][23][24][25][26][27][28][29][30][20][23][25][27][30]
