ABM INDUSTRIES INC /DE/

ABM Industries Incorporated, which operates through its subsidiaries (collectively referred to as ABM, we, us, our, or the Company ), is a leading provider of facility maintenance, engineering and infrastructure solutions with a mission to make a difference, every person, every day . Our history dates back to 1909, when American Building Maintenance Company began as a window washing company in San Francisco with one employee. In 1985, we were incorporated in Delaware under the name American Building Maintenance Industries, Inc., as the successor to the business originally founded in 1909. In 1994, we changed our name to ABM Industries Incorporated. Since that time, we have grown into a multi-segment facility solutions company, primarily through strategic acquisitions and new service offerings, increasing our revenue to more than $8.5 billion. The acquisitions of OneSource and Linc Group in the early 2000s established ABM as a leader in the commercial janitorial market and also enhanced our ability to be a full-service facility solutions provider with new service offerings, including lighting, mechanical, and electrical technical solutions. With demand increasing for industry-specific service providers, the acquisition of Air Serv established Aviation as our first industry group. In recent years, we have strategically acquired companies in the United Kingdom ( UK ) and the Republic of Ireland ( Ireland ), which expanded our janitorial and technical solutions businesses overseas.
