Andersen Group Inc. is a U.S.-focused provider of independent tax, valuation and financial advisory services, built on the legacy Andersen brand and founded in 2002. It reported $838.7 million of revenue in 2025, up from $731.6 million in 2024, but swung to a net loss of $(130.2) million driven primarily by issuance of new profits interest units and equity restructuring costs versus net income of $134.8 million a year earlier.
The company employs over 2,300 people across 26 U.S. locations and accesses more than 50,000 professionals globally through Andersen Global.
