Andersen Group Business Summary

Andersen Group Inc (ANDG) is a premier professional services firm that generates revenue through fee-based independent tax, valuation, and financial advisory services. Following its December 2025 initial public offering on the New York Stock Exchange, the company has structured its operations into four primary segments: Tax, Valuation, Financial Advisory, and a newly launched Consulting practice. Unlike its larger peers, Andersen intentionally avoids audit and attest services to eliminate regulatory conflicts of interest, catering specifically to high-net-worth individuals, family offices, private equity funds, and multinational corporations. The company competes directly with Big Four firms such as Deloitte, EY, KPMG, and PwC, as well as mid-market players like RSM and CBIZ Inc. Andersen distinguishes itself as the leading global, non-audit alternative, leveraging a platform that spans over 180 countries through its Andersen Global network. The firm was founded in 2002 as WTAS by a group of 23 former Arthur Andersen partners led by Mark Vorsatz, who currently serves as Chairman and CEO. The leadership team includes Chief Financial Officer Neal Livingstone, formerly of Freshfields and Dentons; U.S. Country Managing Director Daniel DePaoli; and Chief Legal Officer William Deckelman, who previously served as General Counsel at DXC Technology. Technology and digital transformation initiatives are overseen by Paul Ernst, an industry veteran appointed in 2025 to lead global technology integration. The company’s Board of Directors features high-profile figures including Lead Independent Director Robert V. Gunderson, Jr. (founding partner of Gunderson Dettmer), Ronald L. Olson (partner at Munger, Tolles & Olson and longtime Berkshire Hathaway director), and John R. Joyce (former CFO of IBM).
