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.
In 2015, we began a comprehensive transformational initiative (" 2020 Vision ") to drive long-term, profitable growth through an industry-based, go-to-market approach. Through this initiative, we centralized key functional areas and industry groups, strengthened our sales capabilities, and initiated investments in service delivery tools and processes to help support standard operating practices that we believe remain foundational to our long-term success.
As part of the transformation initiative, we also evaluated all of our service offerings and sold our Security and Government Services businesses, which did not align with our long-term focus on specialized industry groups.
