Andersen Group (ANDG) secondary offering of 4.3M Class A shares by selling stockholders; company receives zero proceeds

This is a secondary offering by selling stockholders of 4,284,457 Class A shares, expandable to 4,927,125 shares if underwriters exercise their full over-allotment option. Because these are shares offered by selling stockholders (not by the company), proceeds go to the selling stockholders, not to Andersen Group Inc.

Post-offering, Class A common stock (the publicly offered class) will hold only 1.9% of voting power while Class B common stock will hold 98.1%. This dual-class structure means public shareholders will have minimal voting control over corporate governance and major decisions.

Post-offering, there will be 18,399,339 Class A shares outstanding (or 112,887,382 if all Class X Umbrella Units are redeemed) and 94,488,043 Class B shares outstanding, for a total of 112,887,382 shares across both classes. The redemption mechanism for Class X Umbrella Units could significantly increase Class A share count.

The company swung from $134.8 million net income in 2024 to a $130.2 million net loss in 2025, a $265 million deterioration. The prospectus does not explain the cause of this swing in the summary section.

Revenue grew 15% year-over-year to $838.7 million in 2025 and 19% in the first half of 2026 to $458.4 million. The company has delivered 15% revenue CAGR since 2003.

Aggregator holds 88.1% economic interest and 98.7% voting control; public shareholders (via Andersen Group Inc.) hold 11.9% economic interest but only 1.3% voting power. This creates significant separation between economic ownership and voting control.

Adjusted EBITDA Margin (non-GAAP) improved from 20% in 2024 to 27% in 2025, even as GAAP net income swung to a $130.2 million loss. This divergence between GAAP and non-GAAP metrics warrants scrutiny of reconciliation items.

Aggregator currently owns 98.7% of voting power and will retain 98.1% after the offering through Class B common stock ownership. This concentration means Aggregator will continue to control all matters requiring stockholder approval, including director elections and major corporate transactions. Public stockholders will have minimal voting influence.

The company intends to use its controlled-company status to opt out of certain NYSE corporate governance requirements. This means public stockholders may have fewer protections than they would at a non-controlled company subject to full NYSE governance standards.

The company serves 13,500 client groups (up 19% year-over-year) and employs over 2,690 personnel in 28 U.S. locations and five other countries. Over 70% of 2025 revenue came from clients engaged for more than three years.

The company has elected the extended transition period for new accounting standards and reduced disclosure requirements. This means the company will not adopt new accounting standards at the same time as other public companies, which may make financial comparisons more difficult for investors.

This is a secondary offering where existing stockholders are selling their shares. The company itself receives no capital from the offering; all proceeds go to the selling stockholders. The selling stockholders have agreed to reimburse the company for all offering expenses.

The company has never paid dividends and does not expect to pay dividends in the foreseeable future. Class B common stock holders are not entitled to cash dividends. Any future dividends are at the board's discretion and depend on results of operations, capital requirements, and other factors.

The company is a holding company whose sole material asset is its indirect ownership in Andersen Tax Holdings LLC. Its ability to pay dividends depends entirely on distributions from AT Umbrella LLC, which may be restricted by state law, contractual obligations, or debt covenants. Class A stockholders may receive less per share than other Class X Umbrella Unit holders because the company must pay taxes and Tax Receivable Agreement obligations.

The company has a dual-class structure where Class B shares (held entirely by Aggregator) carry ten votes per share while Class A shares (offered to the public) carry one vote per share. After this offering, Aggregator will control 98.1% of the voting power despite holding a minority economic interest. This concentration means public shareholders have minimal ability to influence director elections, amendments to organizational documents, or major corporate transactions including change-of-control events.

The company qualifies as a controlled company under NYSE rules because Aggregator holds over 50% of the voting power. While the company currently has a majority-independent board and an independent compensation committee, it relies on the controlled-company exemption for certain governance matters: the full board (not just the compensation committee) determines CEO compensation, and the company has no nominating committee. The company may in the future reduce board independence or eliminate the compensation committee entirely. Public shareholders lack the governance protections standard at non-controlled companies.

The company estimates it will pay approximately $1,037.4 million over 15 years to certain Class X Umbrella Unit holders under the Tax Receivable Agreement, with annual payments ranging from $56.7 million to $100.5 million. These payments represent 85% of tax savings the company realizes from basis step-ups when Class X Umbrella Units are exchanged for Class A common stock. The company notes it could make payments greater than actual cash tax savings and may not be able to recoup those payments.

The company has issued Class H Aggregator Units that entitle holders to aggregate cash distributions of approximately $208.3 million over up to seven years, representing post-service obligations to retiring and retired Managing Directors. AT Umbrella LLC issued a promissory note (the HO Note) in the principal amount of approximately $162.3 million with an 8-year repayment period and 7.63% interest to fund a portion of these payments.

Executive officers, directors, and selling stockholders are locked up for 90 days after this prospectus date, though underwriters may waive the restriction early. After the lock-up expires, up to 94,488,043 additional shares of Class A common stock (issuable upon redemption of Class X Umbrella Units and LTIP Units held by Aggregator) will become eligible for sale, subject to vesting and transfer restrictions. The CEO has an additional 18-month lock-up from the IPO date. Large-scale selling after lock-up expirations could depress the stock price.

The company has never paid dividends and does not plan to pay them in the foreseeable future. Any future dividends are at the board's sole discretion and depend on financial condition, results, cash needs, capital requirements, and contractual or legal restrictions. Investors seeking current income will not receive it from this stock; returns depend entirely on share-price appreciation.

AT Umbrella LLC issued notes (CA Notes) to Aggregator with aggregate principal of approximately $187.8 million, corresponding to Member Notes issued to Management Holdco members for their capital account balances as of December 16, 2025. These notes have repayment periods ranging from two to seven years and accrue interest between 6.31% and 7.50%.

Class X Aggregator Units held by members vest based on prior service years, ranging from 5% vested (fewer than 2 years of service) to 50% vested (greater than 10 years of service) at the time of the IPO. Unvested units vest at 20% per year over five years of continued employment. Members can only redeem units up to a cumulative limit of 20% per 12-month period after the IPO, restricting liquidity for unit holders.

The company has opted out of Delaware's standard anti-takeover statute (Section 203) but adopted similar restrictions in its charter. These provisions block business combinations with any holder of 15%+ voting stock for three years unless the board pre-approved the transaction or the holder acquired 85%+ of voting stock. The charter exempts Aggregator and its affiliates from these restrictions, meaning the controlling investor can transact freely while other large holders face a three-year freeze-out.

The board can issue up to 100 million preferred shares with any rights (including super-voting rights) without stockholder approval. This blank-check preferred stock is a standard anti-takeover tool that allows the board to dilute or block an unwanted acquirer by issuing preferred shares to a friendly party or with terms that make a takeover prohibitively expensive.

After the Triggering Event (likely when Aggregator's ownership falls below a threshold), removing a director requires both cause and a 75% supermajority vote. Before the Triggering Event, directors can be removed without cause by a simple majority. This high threshold post-Triggering Event entrenches the board and makes it nearly impossible for public stockholders to remove directors even if they control a majority of votes.

After the Triggering Event, amending key governance provisions (special meeting rules, business combination restrictions, charter/bylaw amendment thresholds) requires a 75% supermajority. This locks in the anti-takeover and board-entrenchment provisions even if public stockholders gain majority voting power, since they would need three-quarters of all votes to change the rules.

The charter requires all Securities Act claims (including IPO disclosure claims) to be brought in federal court, despite the Securities Act granting concurrent state/federal jurisdiction. The Delaware Supreme Court upheld such provisions, but the company acknowledges uncertainty whether federal courts will enforce it. This provision benefits the company, directors, and underwriters by channeling claims to a single forum and may limit stockholders' choice of venue.
