Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K. The Company’s business experiences seasonal fluctuations in revenue and net income, with a more significant portion of revenue typically realized in the first and third quarters of each year predominantly due to timing of major tax filing deadlines. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial condition, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2026.
The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include but are not limited to the assessment of the recoverability of goodwill and intangible assets, valuation and expected lives of tangible and intangible assets, allowance for credit losses, and certain accrued liabilities. Changes in circumstances could cause actual results to differ materially from these estimates. The Company has consistently applied the accounting policies for the periods presented as described in the consolidated financial statements contained in the annual report for the year ended December 31, 2025.
The unaudited condensed consolidated financial statements include the results of the Company and its subsidiaries. As the Reorganization Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. Prior to the Reorganization Transactions, Andersen Group Inc. had no operations. All significant intercompany transactions and balances have been eliminated during consolidation.
Principles of Consolidation and Noncontrolling Interest
Principles of Consolidation and Noncontrolling Interest
The accompanying unaudited condensed consolidated financial statements include the accounts of AT Umbrella LLC and its 100% wholly owned subsidiaries. AT Umbrella LLC is a Variable Interest Entity (“VIE”), as defined in ASC Topic 810 (“ASC 810”), Consolidation. ASC 810 requires the consolidation of VIEs in which the entity is defined as the primary beneficiary of the VIE. To be a primary beneficiary, an entity must have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, among other factors. The Company has assessed its variable interests in this entity and determined that the Company is the primary beneficiary of AT Umbrella LLC and its subsidiaries. In completing the assessment, the Company identified the activities that it considers most significant to the economic performance of this entity and determined that the Company has the power to direct those activities. As a result, AT Umbrella LLC and its subsidiaries’ financial position and results of operations are consolidated in the Company’s unaudited condensed consolidated balance sheet and unaudited condensed consolidated statement of operations.
All significant intercompany balances and transactions have been eliminated in consolidation. The assets and liabilities of AT Umbrella LLC represent substantially all of the consolidated assets and liabilities of Andersen Group, Inc. Andersen Group, Inc., has not had any material operations on a standalone basis since its inception, and all of the operations of the Company are carried out by AT Umbrella LLC and its subsidiaries.
A noncontrolling interest in a consolidated subsidiary represents the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company. Redeemable noncontrolling interest was classified as temporary equity at December 31, 2025 because the Class X Umbrella Units contained certain redemption features that were not solely within the control of the Company. On March 24, 2026, an amendment to the AT Umbrella LLC Limited Liability Company Agreement was executed. The amendment modified the redemption provisions of Class X Umbrella Units held by Aggregator, which allow for the Company to elect for settlement in cash instead of settlement in the Company's Class A common stock. Under the revised terms, the Company may elect to redeem Class X Umbrella Units held by Aggregator for cash only if the cash proceeds are sourced from a qualifying offering of its Class A common stock. As a result of these changes, the redeemable noncontrolling interest was prospectively reclassified from temporary equity into permanent equity as the conditions for temporary equity classification are no longer met. See Note 11 for further information on the redeemable noncontrolling interest and the related accounting policies prior to the reclassification from temporary equity into permanent equity.
The presentation of net income is modified to present earnings and other comprehensive income attributed to controlling and noncontrolling interests.
The noncontrolling interest on the unaudited condensed consolidated statement of operations represents the portion of earnings or loss attributable to the ownership interests in AT Umbrella LLC held by Aggregator. Net income or loss attributable to noncontrolling interests is allocated in accordance with the contractual distribution rights of the holders under AT Umbrella LLC's Limited Liability Company Agreement. Those contractual rights reflect the relative participation of Class X holders and, when applicable, LTIP Unit holders. LTIP Unit holders participate only after the applicable contractual hurdle amounts are satisfied, and certain LTIP awards include catch-up provisions that may affect the allocation of earnings after those hurdle amounts are met.
The Company does not have any controlling interest in, and is not the primary beneficiary of, any other member firm of Andersen Global. Accordingly, these entities are considered related parties solely as a result of the memberships in the Swiss verein discussed above. These member firm entities are not consolidated in the Company’s unaudited condensed consolidated financial statements.
Variable Interest Entity One of the non-U.S. Andersen Global member firms is a VIE. The Company has assessed its variable interests in this entity and determined that the Company is not the primary beneficiary. In completing the assessment, the Company identified activities it considers most significant to the economic performance of this entity and determined that the Company does not have the power to direct those activities. As a result, that entity’s financial position and results of operations are not consolidated in the Company’s unaudited condensed consolidated balance sheet and unaudited condensed consolidated statement of operations. The Company's carrying value and exposure to loss is comprised of loans to the VIE included in loans and notes receivable from affiliates, net of allowance for credit losses and amounts due from the VIE included in prepaid expenses and other current assets.
Segment Information
Segment Information
ASC Topic 280, Segment Reporting establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise where discrete financial information is available and evaluated regularly by the Chief Operating Decision Maker (“CODM”), in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer (“CEO”). The Company operates in one segment based upon the financial information used by its CODM in evaluating the financial performance of its business and allocating resources. The single segment represents the Company’s core business of providing tax, valuation, financial advisory and related consulting services to its clients. See Note 18 for further information on the Company’s reporting segment.
Amounts Payable to Related Parties Pursuant to Tax Receivable Agreement
Amounts Payable to Related Parties Pursuant to Tax Receivable Agreement
In connection with the IPO and Reorganization Transactions, the Company entered into the TRA with certain pre-IPO owners that provides for the payment to certain holders of Class X Umbrella Units who are or may become parties to the TRA from time to time 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company realizes or is deemed to realize (determined by using assumptions regarding combined state and local income tax rates) as a result of (i) any increase in tax basis in the assets of AT Umbrella LLC and its flow-through subsidiaries resulting from purchases of Class X Umbrella Units from such Class X Umbrella Unit holders with the proceeds of the IPO or resulting from exchanges of Class X Umbrella Units for at Andersen Group Inc.’s election, shares of Class A common stock or cash in the future; and (ii) certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments that are made under the TRA. The TRA will make certain simplifying assumptions regarding the determination of the cash savings that are realized or are deemed to realize from the covered tax attributes, which may result in payments pursuant to the TRA in excess of those that would result if such assumptions were not made. No party to the TRA will reimburse the Company for any payments previously made if such basis increases or other benefits are subsequently disallowed, except that excess payments made to the TRA parties will be netted against future payments that would otherwise be made under the TRA, if any, after determination of such excess. The Company accounts for amounts payable under the TRA in accordance with ASC Topic 450, Contingencies. As such, subsequent changes in the fair value of the TRA liability between reporting periods are recognized in the consolidated statement of operations.
The Company has not yet incurred a liability in connection with the TRA.
Earnings per Share
Earnings per Share
Basic earnings per share is calculated by dividing net income by the weighted-average number of shares of the Company’s Class A common stock outstanding for the period, without consideration for potential dilutive shares of common stock. Shares of Class B common stock and RSUs are not entitled to receive any distributions or dividends and are therefore excluded from this presentation since they are not participating securities. Diluted earnings per share is computed by dividing net income attributable to holders of Class A common stock by the weighted average number of shares of Class A common stock outstanding, plus the effect of all dilutive securities as calculated using the if-converted and treasury stock methods, as appropriate.

Participating securities exist at AT Umbrella LLC, a non-wholly owned consolidated subsidiary of the Company. As such, the Company applies the more dilutive of the treasury stock or if-converted methods and the two-class method to allocate undistributed earnings or losses of AT Umbrella LLC. In doing so, the Company determines the portion of AT Umbrella LLC’s earnings attributable to the Company and accordingly reflects in earnings available to common stockholders in the Company’s calculation of basic and diluted earnings per share.
The Company did not include earnings per unit for the pre-IPO period as part of its financial statements. All earnings prior to the completion date of the IPO, were entirely allocable to the noncontrolling interest and, as a result, earnings per share information is not applicable for reporting periods prior to this date, including the three months ended March 31, 2025. Consequently, only earnings per share for net earnings for the three months ended March 31, 2026 are presented.
Recently Issued Accounting Pronouncements
Recently Issued Accounting Pronouncements
Changes to U.S. GAAP are established by the Financial Accounting Standard Board ("FASB") in the form of Accounting Standards Updates ("ASUs") to the FASB Accounting Standards Codification ("Codification"). ASUs issued which are not specifically listed below were assessed and have already been adopted in a prior period or determined to be either not applicable or are not expected to have a material impact on the Company’s consolidated financial statements and related disclosures.
In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which added a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. The guidance is effective for all entities for annual periods beginning after December 15, 2025. The Company adopted ASU 2025-05 as of January 1, 2026 and such adoption did not have a significant impact on the Company's condensed consolidated financial statements.
Recent Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. Early adoption is permitted. Upon adoption, the guidance may be applied prospectively or retrospectively. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. As an emerging growth company, the Company has elected the extended transition period for complying with new or revised accounting standards and this ASU has not yet been adopted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement (Topic 220): Reporting Comprehensive Income - Expense Disaggregation Disclosures, Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires public business entities to disclose, in interim and annual reporting periods, additional information about certain expenses in the consolidated financial statements. The amendments in this ASU will be effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted and is effective on either a prospective basis or retrospective basis. The Company is currently evaluating the potential impact that the adoption of this standard will have on its consolidated financial statements.
In May 2025, the FASB issued ASU No. 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“VIE”), which provides clarifying guidance on determining the accounting acquirer in certain transactions involving VIEs. The update aims to improve consistency and comparability in financial reporting. The guidance will be effective for all entities for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. Upon adoption, the guidance will be applied prospectively. The Company is currently evaluating the potential impact that the adoption of this standard will have on its consolidated financial statements.
In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements in Accounting for Internal-Use Software, which replaced the “project stage” model with a principles-based framework for cost recognition and capitalization of internal-use software. The update requires companies to capitalize internal-use software costs when management authorizes and commits funding for the software project and when it is probable the project will be completed and the software will be used to perform the function intended. The guidance will be effective for all entities for annual periods beginning after December 15, 2027, including interim periods within those annual periods. Early adoption is permitted. Upon adoption, the guidance may be applied prospectively or retrospectively. The Company is currently evaluating the potential impact that the adoption of this standard will have on its consolidated financial statements.
In September 2025, the FASB issued ASU No. 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration From a Customer in a Revenue Contract. ASU 2025-07 introduces guidance for applying derivative
accounting to contracts that include features tied to the operations or activities of one of the parties to the contract. It also aims to reduce diversity in how share-based payments are accounted for in revenue contracts. ASU 2025-07 will be effective for the annual periods beginning after December 15, 2026 with early adoption permitted. The Company is currently evaluating the potential impact that the adoption of this standard will have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow- Scope Improvements. The amendments in this ASU do not change the fundamental nature of interim reporting or expand or reduce current interim disclosure. The amendments in this ASU clarify the guidance in ASC Topic 270 by providing a comprehensive list of required interim disclosures and codifying a disclosure principle that requires the Company to disclose events and changes that occur after the end of the most recent annual reporting period that have a material impact on its consolidated financial statements. The amendments in this ASU are effective for interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-12, Codification Improvements (Topic 815). The amendments in this ASU update the FASB Accounting Standards Codification for a broad range of Topics arising from technical corrections, unintended application of the Codification, clarifications, and other minor improvements. The amendments in this ASU are effective for all entities for annual periods beginning after December 15, 2026, and interim periods within those annual periods. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements.
