Andersen Group Inc. (ANDG) is registering a secondary offering of 4,284,457 shares of Class A common stock for resale by selling stockholders at $44.00 per share, with an underwriters’ option for up to an additional 642,668 shares. Andersen Group will not receive any proceeds; all net proceeds of about $180.0 million before expenses go to the selling stockholders.
The offering reflects redemptions of Class X Aggregator and Class X Umbrella Units paired with Class B shares into Class A shares. Andersen has a dual-class structure where Class A has one vote and non-economic Class B has ten votes per share; Aggregator will hold about 98.1% of combined voting power after the offering, so the company remains a NYSE “controlled company.”
The firm provides tax, valuation and financial advisory services and does not perform audits. Revenue grew from $731.6 million in 2024 to $838.7 million in 2025 and to $458.4 million for the six months ended June 30, 2026. Results swung from $134.8 million net income in 2024 to a $130.2 million net loss in 2025, then to $7.6 million net income for the first half of 2026, while Adjusted EBITDA Margin was 27% in 2025 and in the first half of 2026.
