Andersen Files Confidential Draft for IPO, Revives Consulting Legacy

Andersen Group has formally taken a significant step toward becoming a publicly traded company, announcing the confidential submission of a draft registration statement on Form S-1 with the Securities and Exchange Commission. The proposed initial public offering (IPO) marks a pivotal chapter for the modern-day successor to the former accounting titan Arthur Andersen.

While the number of shares to be offered and the price range remain undisclosed, the IPO is expected to proceed following the SEC's review process and is subject to prevailing market conditions. The move signals Andersen’s readiness to scale its global operations and deepen its footprint across core service lines.

This development follows February’s announcement to relaunch Andersen Consulting—an iconic name originally spun off from Arthur Andersen in 2000 before evolving into Accenture. Unlike its ill-fated predecessor, which collapsed in the early 2000s under the weight of high-profile accounting scandals, the reimagined Andersen has deliberately distanced itself from auditing. Instead, it focuses on tax, legal, and valuation services, all of which are expected to remain intact post-IPO.

Founded in 2002 as WTAS by CEO Mark Vorsatz and 22 former Arthur Andersen partners, the firm rebranded to Andersen Tax in 2014 after acquiring the Andersen trademarks and copyrights. Under Vorsatz’s leadership, Andersen has grown from a U.S.-based tax firm into a global enterprise with more than 19,000 professionals and operations in over 500 locations worldwide. In the U.S. alone, the firm employs over 2,000 professionals across 24 cities.

The consulting arm—Andersen Consulting—will deliver a broad suite of services, including human capital management, cybersecurity, business transformation, strategy, technology, artificial intelligence, and sustainability. Its current client portfolio features an impressive array of global brands such as Abbott, BMW, Cisco, Heineken, IKEA, ING, LEGO, Mercedes-Benz, Michelin, Microsoft, Pizza Hut/Sapphire, T-Mobile, and Toyota.

The IPO positions Andersen to expand its influence in the professional services market while leveraging the legacy of a once-dominant brand, reimagined for a modern, diversified service economy.
