Andersen Group Inc. (ANDG)

Andersen is a leading provider of independent tax, valuation, and financial advisory services to individuals and family offices, businesses, and institutional clients across the United States, founded in 2002 by former Arthur Andersen professionals and built on that firm's traditions and culture. The company has deliberately avoided audit and financial statement attestation services, allowing it to offer a comprehensive suite of non-audit services without auditor independence restrictions. Its primary service offerings include Private Client Services (income tax planning, trust and estate planning, charitable giving, family office advisory, and wealth management for high-net-worth individuals and families), Tax Services (M&A transaction services, state and local tax, international tax, and tax technology automation for businesses), Alternative Investments (tax and financial services for family offices, hedge funds, private equity, venture capital funds, real estate funds, and funds-of-funds), and Valuation Services (tax valuation, financial reporting valuation, and fixed asset/real estate valuation), supported by a U.S. National Tax Office staffed with former IRS and Treasury professionals.

The company serves a diverse client base spanning industries such as financial services, consumer products, healthcare, hospitality, manufacturing, pharmaceuticals/biotech, private equity, real estate, technology, and venture capital, with low client concentration (top ten client groups representing about 5% of revenue) and high client retention (over 70% of 2025 revenue from clients of more than three years). As of December 31, 2025, Andersen employed over 2,300 professionals across 26 U.S. locations and served approximately 12,350 client groups, with global reach facilitated through its founding membership in Andersen Global, a Swiss association of over 300 member and collaborating firms comprising more than 50,000 professionals in over 180 countries. The firm's growth strategy centers on expanding existing client relationships, attracting new clients, broadening service offerings (including consulting, investment banking, global mobility, and international legal services), pursuing selective acquisitions and business combinations, and expanding internationally by leveraging the Andersen brand and its Andersen Global network.
