Tax advisory firm Andersen Group is targeting a valuation of up to $1.75bn in its initial public offering (IPO) in the US. 

In September 2025, the company filed a registration statement with US Securities and Exchange Commission (SEC) to list its shares on New York Stock Exchange (NYSE) under the symbol ANDG.  

The IPO aims to offer 11 million shares at an estimated price range between $14 and $16 per share, with the goal of raising up to $176m. 

A thirty-day option will be available for underwriters to buy as many as 1,650,000 additional shares at the IPO price, excluding underwriting fees and commissions.  

Morgan Stanley and UBS Investment Bank have been appointed as lead book-running managers for this offering.  

Deutsche Bank Securities, Truist Securities and Wells Fargo Securities are also involved as book-running managers, while Baird and William Blair are listed as additional book-running managers. 

Andersen Group operates in the US with a focus on tax, valuation and financial advisory services for individuals, family offices, business entities and alternative investment funds.  

Its network extends internationally through member and collaborating firms delivering tax, legal, valuation and consulting services in more than 180 countries at more than 1,000 sites, employing upwards of 3,000 partners and 50,000 staff. 

The firm’s background is linked to Arthur Andersen’s closure in 2002 following its involvement with Enron.  

Arthur Andersen was convicted of obstruction of justice related to the Enron case; however, this conviction was later overturned by the Supreme Court.  

After Arthur Andersen ceased operations, HSBC acquired a portion of its tax division through Wealth & Tax Advisory Services (WTAS). 

This entity subsequently separated from HSBC in a management buyout before adopting the Andersen Tax name in 2014.  

This rebranding marked the start of what is now known as Andersen Group.
