Brookfield Business Holding Corporation (BBHC) is a Canadian holding company that owns controlling interests in three operating businesses: CDK Global, BRK Ambiental, and Multiplex. CDK Global is a U.S.-based provider of cloud software to automotive dealerships and OEMs, helping dealerships manage sales, financing, service, and inventory. CDK earns recurring subscription and technology service fees, making it a relatively predictable, high-margin business with high customer switching costs. BRK Ambiental is a Brazilian private water and wastewater utility serving residential and government customers, earning regulated, recurring service fees under long-term concession contracts. Multiplex is a construction services business focused on large-scale, complex commercial and social infrastructure projects, primarily in the U.K. and Australia, earning revenue on fixed-price construction contracts. BBHC operates as a private equity-style holding company — its core model involves acquiring businesses at attractive valuations, improving their operating performance, and recycling capital by selling mature assets and redeploying proceeds into new acquisitions. Brookfield manages BBHC's investment decisions and strategy via a master services agreement, and Brookfield's active operational involvement is central to its value creation approach. BBHC completed a merger with Brookfield Business Partners in March 2026, simplifying its structure into a single publicly traded corporate entity.
