RBA vs ACM Comparison

RB Global has evolved into a leading global marketplace that connects buyers and sellers of commercial assets and vehicles. It is the result of the 2023 combination of Ritchie Bros. and IAA. Ritchie Bros.' roots were as an auctioneer facilitating transactions of commercial, construction, and transportation equipment (excavators, bulldozers, forklifts, and commercial trucks and trailers). However, it has evolved into an omnichannel marketplace. IAA has similar roots, though primarily focused on the salvage auction segment for consumer automobiles. The group provides ancillary services including title processing, transportation/towing, financing, data and appraisal, and so on. Its activities are international, though skewing approximately two-thirds to North America.

Aecom is one of the largest global providers of design, engineering, construction, and management services. It serves a broad spectrum of end markets including infrastructure, water, transportation, and energy. Based in Los Angeles, Aecom has a presence in over 150 countries and employs 51,000. The company generated $16.1 billion in sales in fiscal 2024.
