**Special Note Regarding Forward-Looking Statements**

This Quarterly Report on Form 10-Q (this Quarterly Report) includes forward-looking statements that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding our future operating results and financial position, our business strategy and plans, market growth, and our objectives for future operations, are forward-looking statements. The words "believe," "may," "will," "estimate," "continue," "anticipate," "design," "intend," "expect," "could," "plan," "potential," "predict," "seek," "should," "would," or the negative version of these words and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, strategy, short- and long-term business operations and objectives, and financial needs. Forward-looking statements contained in this Quarterly Report include, but are not limited to, statements about:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount and timing of any payments under the Tax Receivable Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other statements regarding our future operations, financial condition, prospects and business strategies.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this Quarterly Report.

These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including those described in Part I, Item 1A "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2025. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

------

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance or achievements. The forward-looking statements made in this Quarterly Report are given only as of the date on which the statements are made. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this Quarterly Report or to conform these statements to actual results or to changes in our expectations, except as required by law.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into or review of all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should read this Quarterly Report and the documents that we reference in this Quarterly Report and have filed with the SEC as exhibits to this Quarterly Report with the understanding that our actual future results, performance, and events and circumstances may be materially different from what we expect.

**ANDERSEN GROUP INC. AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1. Organization and Business Description**

Andersen Group Inc. was formed on April 16, 2025 for the purpose of facilitating an initial public offering ("IPO") and other related transactions in order to operate the business of AT Umbrella LLC. Andersen Group Inc. is a holding company, and its sole material asset is its indirect ownership interests in Andersen Tax Holdings LLC through its ownership of approximately 11.4% of the Class X Umbrella Units in AT Umbrella LLC, which in turn owns all ownership interests in Andersen Tax Holdings LLC and its 100% wholly owned subsidiaries (collectively, the "Company"). The Company is a national professional services firm focused on providing a wide range of tax, valuation, financial advisory, and related consulting services (including certain services acting as a registered investment adviser). As of March 31, 2026, the Company has 27 offices in 15 states and the District of Columbia.

Prior to the Company completing its IPO and Up-C restructuring (the "Reorganization" or "Reorganization Transactions"), the Company historically conducted business through Andersen Tax Holdings LLC and its subsidiaries, including Andersen Tax LLC. Andersen Tax Holdings LLC was formed on December 31, 2007, to execute the acquisition of an existing business by MD Management LLC and MD Investment LLC (collectively, the "Management Holdcos"). On June 26, 2013, Andersen Tax LLC became a member firm in Andersen Global, a Swiss verein established under articles 60-79 of the Swiss Civil Code. Each member firm provides services in a defined geographic area and is subject to the laws and professional regulations of the particular country or countries in which it operates. The Articles of Association of Andersen Global provide for the autonomy of its member firms and specifically require each member firm to retain and remain solely responsible for its own legal obligations to third parties and its partners or managing directors and employees, arising before or after the formation of Andersen Global, including all debts and obligations.

***Initial Public Offering***

On December 18, 2025, the Company completed its IPO of 12,650,000 shares of Class A common stock at an offering price of $16.00 per share, including 1,650,000 shares of Class A common stock issued pursuant to the underwriters' over-allotment option. The Company received net proceeds of $188.2 million, net of underwriting discounts and commissions of $14.2 million, but before deducting offering costs of $9.9 million. The Company used the proceeds to purchase 12,650,000 newly-issued membership units of AT Umbrella LLC ("Class X Umbrella Units") at a price per unit equal to the IPO price, net of underwriting discounts and commissions.

***Summary of the Reorganization and Other Transactions Completed in Connection with the IPO***

In connection with the IPO, a series of transactions comprised of a reorganization, offering and other financing transactions were completed. The following summarizes the Reorganization Transactions that were completed as of the date of IPO:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Andersen Group Inc. amended and restated its certificate of incorporation, pursuant to which it is authorized to issue two series of common stock, Class A and Class B. Class A common stock has one vote per share and is entitled to economic rights. Class B common stock has ten votes per share and is not entitled to economic rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Management Holdcos merged into Andersen Aggregator LLC ("Aggregator"). Existing common units and profits interest units were converted to Class X Aggregator Units. A percentage of the new Class X Aggregator Units were subject to vesting conditions for active managing directors who perform services for Andersen Tax LLC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AT Umbrella LLC was formed. Andersen Aggregator LLC contributed 100% of its equity interests in Andersen Tax Holdings LLC to AT Umbrella LLC in exchange for Class X Umbrella Units. Immediately after this contribution, AT Umbrella LLC became the managing member of Andersen Tax Holdings LLC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Andersen Group Inc. issued to Andersen Aggregator LLC 98,302,500 shares of Class B common stock in exchange for the payment by Aggregator of the aggregate par value of the Class B common stock that is received.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Management Holdcos issued to each of their members a promissory note in a principal amount equal to such member's and its related transferee's aggregated capital account balance in respect of such Management Holdco as of December 16, 2025, with repayment over a seven-year period for each family of related notes with a principal

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

balance of at least $550,000, either a three- or seven-year period for each family of related notes with a principal balance of less than $550,000 and a period of between two to seven years for notes issued to certain retiring and retired managing director members of the Management Holdcos (the "Member Notes"). Additionally, AT Umbrella LLC issued corresponding notes to Aggregator (the "Capital Account Notes") with aggregate principal amounts of approximately $187.8 million, equal to the sum of the aggregate principal amounts of the Member Notes, to be paid over the same two- to seven-year period, respectively. The Capital Account Notes accrue interest between 6.31% to 7.50%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In connection with the reorganization of the Management Holdcos, Aggregator issued Class H Aggregator Units entitling certain retiring and retired managing director members of the Management Holdcos subject to certain terms and conditions, to certain cash distributions paid over a period of up to seven years relating to payment of certain post-service obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AT Umbrella LLC issued to Aggregator a promissory note in a principal amount of approximately $162.3 million with repayment occurring over an eight-year period relating to payment of the above-mentioned post-service obligations to certain retiring and retired managing director members of the Management Holdcos (the "Holdover Note"). The Holdover Note accrues interest at 7.63%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Andersen Group Inc. entered into a Tax Receivable Agreement ("TRA") with Aggregator concurrent with the Reorganization Transactions, which requires the Company to pay to certain holders of Class X Umbrella Units who are or may become parties to the TRA (the "TRA Parties") from time to time 85% of the amount of tax benefits, if any, that are actually realized (or in some circumstances that are deemed to realize) 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 exchanges of Class X Umbrella Units for 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 the Company will make under the TRA.

Class X Umbrella Units held by pre-IPO common unitholders and profits interest units at AT Umbrella LLC ("LTIP Units") are exchangeable for Class A common stock from Andersen Group Inc.

The Reorganization Transactions were accounted for as a transaction between entities under common control. As a result, the financial statements for periods prior to the IPO and the Reorganization have been adjusted to combine the previously separate entities for presentation purposes. As the managing member, Andersen Group Inc. operates and controls all of the business and affairs, and through AT Umbrella LLC and its subsidiaries, conducts the business of Andersen Tax LLC. Andersen Group Inc. consolidates AT Umbrella LLC and its subsidiaries in its consolidated financial statements and reports a redeemable noncontrolling interest related to the Class X Umbrella Units held by the pre-IPO common unitholders and the LTIP Units in the consolidated financial statements.

The following summarizes the other transactions completed in connection with the IPO:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AT Umbrella LLC granted LTIP Units to Aggregator in connection with the earlier appointment of additional managing directors during 2025, and Aggregator issued corresponding Aggregator LTIP Units to such managing directors. Andersen Group Inc. issued to Aggregator shares of Class B common stock equal in number to the maximum number of Class X Umbrella Units issuable upon exchange of such LTIP Units issued to Aggregator in exchange for the payment by Aggregator of the aggregate par value of the Class B common stock that is received. LTIP Units in AT Umbrella are economically similar to stock options. Each LTIP Unit has a per unit hurdle price, which is economically similar to the exercise price of a stock option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Andersen Group Inc. granted 5,440,720 restricted stock units (RSUs) under the 2025 Equity Incentive Plan concurrent with the IPO.

**Note 2. Summary of Significant Accounting Policies**

***Significant Accounting Policies***

There have been no material changes in the Company's significant accounting policies as of and for the three months ended March 31, 2026, as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 filed with the Securities and Exchange Commission ("SEC") on March 27, 2026.

***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***

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.

**ANDERSEN GROUP INC. AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

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.

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. As of March 31, 2026 and December 31, 2025, the total carrying value of these items was $0.2 million and $0.2 million, respectively. As of March 31, 2026 and December 31, 2025, the Company's maximum exposure to loss related to the loans receivable and amounts due from the VIE was $7.7 million and $6.9 million, respectively, excluding the allowance for credit loss on the loans receivable from the VIE.

***Emerging Growth Company Status***

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies.

The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is no longer an emerging growth company or affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these unaudited condensed consolidated financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards based on public company effective dates.

***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***

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***

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***

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.

Substantially all revenue was from services provided in the United States for the three months ended March 31, 2026 and 2025.

***Remaining Performance Obligations***

The revenue recognition standard provides exemptions to the requirements for disclosure of the total transaction price allocated to unsatisfied performance obligations as of the reporting date for performance obligations within contracts of one year or less. The majority of the Company's contracts with clients have a duration of one year or less. For contracts with a stated duration exceeding one year, these agreements allow both the Company and the client to cancel or terminate without substantial penalty. Therefore, the contract duration does not extend beyond the goods and services already transferred when cancellation or termination rights exist without substantial penalty. As such, the Company does not disclose the total transaction price allocated to unsatisfied performance obligations.

***Contract Balances***

In the three months ended March 31, 2026, the Company recognized revenue of approximately $7.8 million that was included in deferred revenue on the consolidated balance sheet as of December 31, 2025. In the three months ended March 31, 2025, the Company recognized revenue of approximately $9.8 million that was included in deferred revenue on the consolidated balance sheet as of December 31, 2024. The opening balance of deferred revenue on January 1, 2025 was $15.6 million.

***Revolving Line of Credit***

In the normal course of business, the Company maintains a $20.0 million revolving line of credit (the "Credit Agreement") with a financial institution. The Credit Agreement is collateralized by substantially all the assets of the Company.

The Credit Agreement includes a sublimit of $5.0 million for standby letters of credit, and the interest rate for cash borrowing under the Credit Agreement is the Prime rate with a floor of 5.0%. As of March 31, 2026 and December 31, 2025, the Company had outstanding standby letters of credit of $1.3 million and $1.3 million, respectively. The Company had no cash borrowings as of March 31, 2026 and December 31, 2025. The Company's outstanding letter of credit is subject to a commitment fee of 1.5% per annum. These fees are included in sales, general and administrative expenses and are immaterial for the three months ended March 31, 2026 and 2025.

In February 2026, the Company amended the Credit Agreement to extend through June 2026. The extension also modified certain terms relating to covenant requirements.

During the three months ended March 31, 2026 and 2025, the Company had no uncured events of default with respect to the financial covenants required by the Credit Agreement.

***Capital Account Notes***

In connection with the reorganization of the Management Holdcos, Aggregator issued Class X Aggregator Units to equity holders of the Management Holdcos who were current Managing Directors and related persons and issued Member Notes representing the undistributed capital account balance payable to all equity holders of the Management Holdcos who had an outstanding capital account balance.

On December 16, 2025, AT Umbrella LLC issued corresponding Capital Account Notes, which are promissory notes to Aggregator with aggregate principal amounts of $187.8 million. The Capital Account Notes are amortized over two to seven years and bear annual interest rates between 6.31% to 7.50%. Payments are made quarterly, consisting of both principal and accrued interest.

The Company may prepay the outstanding principal amounts partially or in full at any time without penalty or premium. Early partial prepayments are applied to reduce the last maturing principal installments first.

In the event of default, including non-payment, breach of representations, or insolvency events, the noteholder may declare the entire principal, accrued interest, and other amounts immediately due and payable. Furthermore, the obligations under the Capital Account Notes are subordinated to AT Umbrella LLC's senior indebtedness.

The Capital Account Notes are governed under the laws of the State of Delaware and are subject to additional terms and conditions as outlined in the original agreements.

***Holdover Note***

In connection with the reorganization of the Management Holdcos, Aggregator issued Class H Aggregator Units entitling certain retiring and retired managing director members of the Management Holdcos subject to certain terms and conditions, to certain cash distributions paid over a period of up to seven years relating to payment of certain post-service obligations.

On December 16, 2025, AT Umbrella LLC issued to Aggregator the Holdover Note in a principal amount of $162.3 million with repayment occurring over an eight-year period relating to payment of the above-mentioned post-service obligations to certain retiring and retired managing director members of the Management Holdcos. The Holdover Note bears interest at a rate of 7.63%. Payments are made quarterly, consisting of both principal and accrued interest.

The Company may prepay the outstanding principal amount partially or in full at any time without penalty or premium. Early partial prepayments are applied to reduce the last maturing principal installments first.

The Company did not incur material loan issuance costs in connection with the Capital Account Notes and Holdover Note.

The fair value of the debt obligations is approximated by the principal amount of the loans as of March 31, 2026. The fair value of the debt obligations is estimated using a discounted cash flow methodology, which includes significant unobservable inputs used in the fair value measurement process for items valued utilizing Level 3 techniques. The Company incurred approximately $6.2 million in interest expense with respect to the Capital Account Notes and Holdover Note during the three months ended March 31, 2026.

**Note 10. Employee Compensation and Benefits**

***Deferred Compensation***

Effective January 1, 2023, the Company established a deferred compensation plan for non-partner employees holding the title of Director who are eligible once they have five or more years of service as a Director. On an annual basis, eligible participants are granted an award payable in equal installments starting in March of the following five years. The annual award is based on each eligible participant's years of service at the Director level and on income allocated to the Management Holdcos prior to the IPO, and to Aggregator after the IPO.

**Note 11. Redeemable Noncontrolling Interest**

In connection with the Reorganization Transactions, Class X Umbrella Units were issued to Aggregator. Aggregator also owns all outstanding shares of the Company's Class B common stock. Under the Limited Liability Company Agreement of AT Umbrella LLC (the "AT Umbrella LLC Agreement"), Aggregator had the right from time to time to cause AT Umbrella LLC to redeem any or all of its Class X Umbrella Units (and cancel paired shares of the Company's Class B common stock), in exchange for, at Andersen Group Inc.'s election, either cash (based on the volume-weighted average market price of a share of the Company's Class A common stock) or shares of Class A common stock, and such exchange, at Andersen Group Inc.'s election, may have been effected as a direct exchange of cash or Class A common stock for Class X Umbrella Units (and the cancellation of paired shares of the Company's Class B common stock) in lieu of such redemption. The redemption election was not considered to be within the control of the Company because the holder of Class B common stock controlled the Company through direct representation on its board of directors. As a result, the noncontrolling interests in AT Umbrella LLC was classified as redeemable noncontrolling interests outside of permanent equity at December 31, 2025.

Redeemable noncontrolling interest was recorded at the greater of the carrying value or redemption amount. In determining the measurement method of redemption value, the Company elected to accrete changes to the redemption value over the period from the date of issuance to the earliest redemption date. The resulting changes to accrete to the redemption value were recorded in equity. If the Company had an accumulated deficit, changes were recorded against additional paid-in-capital until there was no additional paid-in capital balance, and then charges were recorded against accumulated deficit. Changes in the redemption value were considered to be changes in accounting estimates and were accounted for prospectively.

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. 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 the Company's 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.

Changes to the value of the redeemable noncontrolling interest during the three months ended March 31, 2026 are summarized as follows (in thousands):

---

***Distributions to Members Related to Their Income Tax Liabilities***

As a limited liability company treated as a partnership for income tax purposes, AT Umbrella LLC does not incur significant federal, state or local income taxes, as these are primarily the obligations of its members. Under the AT Umbrella LLC Agreement, the AT Umbrella LLC is required to distribute cash, to the extent that it has cash available, on a pro rata basis to its members to the extent necessary to cover the members' tax liabilities, if any, with respect to each member's share of the AT Umbrella LLC's taxable earnings. During the three months ended March 31, 2026, the Company paid distributions totaling $6.3 million to Aggregator in satisfaction of member tax liabilities.

***AT Umbrella LLC Agreement***

As of March 31, 2026, 12,650,000 Class X Umbrella Units are held by Andersen Group Inc. corresponding to 12,650,000 shares of Andersen Group Inc. Class A common stock issued and outstanding as of such date. The remaining 98,826,563 Class X Umbrella Units outstanding as of March 31, 2026 correspond to 97,850,000 shares of Andersen Group Inc.

**ANDERSEN GROUP INC. AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

Company, this obligation applies to shares of Class A common stock or other economic equity securities, and for Aggregator, to Class X Aggregator Units or exchangeable equity instruments. Concurrently, any net proceeds received from these equity issuances by the Company or Aggregator must be contributed to AT Umbrella LLC, unless otherwise used to fund specific expenses. Similar parity is maintained in equity transactions such as repurchases or redemptions involving the Company, Aggregator, or AT Umbrella LLC.

**Note 13. Equity-Based Compensation**

*2025 Equity Incentive Plan*

On December 6, 2025, the board of directors of Andersen Group Inc. approved the Company's 2025 Equity Incentive Plan. The 2025 Equity Incentive Plan provides for the grant of nonstatutory stock options (NSOs), stock appreciation rights (SARs), restricted shares, restricted stock units (RSUs) and other equity-based awards. As of March 31, 2026 the Company has reserved 12,290,828 shares of Class A common stock in connection with the 2025 Equity Incentive Plan. On the first day of each January during the term of the 2025 Equity Incentive Plan, beginning on January 1, 2026 and ending on (and including) January 1, 2035, the number of shares of Class A common stock that may be issued under the 2025 Equity Incentive Plan will increase by a number of shares equal to the lesser of (a) 5% of the outstanding shares of all classes of common stock on the last day of the immediately preceding fiscal year or (b) such lesser number of shares (including zero) that the plan administrator determines for purposes of the annual increase for that fiscal year. The Company will recognize forfeitures as they occur.

Concurrently with the IPO, the Company granted new RSUs to employees. The RSUs granted in 2025 have a time-based vesting requirement wherein 1/6th of the total number of RSUs subject to the award will vest on each annual anniversary of the vesting commencement date, subject to the recipient's continuous service as an employee to the Company, a parent, subsidiary or affiliate through the applicable vesting date. Upon vesting, the RSUs are convertible into Class A common stock; unvested RSUs are not considered outstanding shares of Class A common stock. The fair value of the RSUs was based on the fair value of a share of Class A common stock at the time of grant, which equates to a weighted-average grant date fair value of $16.00 per unit.

The following table summarizes the information about RSU activity of Andersen Group Inc. during the three months ended March 31, 2026:

---

| | |
|:---|:---|
| | **Number of Units** |
| **Outstanding as of December 31, 2025** | **5419378** |
| Granted |  |
| Vested |  |
| Forfeited | (258375) |
| **Outstanding as of March 31, 2026** | **5161003** |

---

Total compensation expense for RSUs was approximately $3.6 million for the three months ended March 31, 2026, of which $2.8 million is included in cost of services and $0.8 million is included in sales, general and administrative expense in the consolidated statement of operations. The unamortized compensation cost related to RSUs of $78.4 million as of March 31, 2026 is expected to be recognized over a weighted-average period of approximately 5.7 years.

*AT Umbrella LLC LTIP Units*

Concurrently with the IPO, AT Umbrella LLC issued AT Umbrella LLC LTIP Units to Aggregator in connection with an earlier appointment of additional Managing Directors during 2025, and Aggregator issued corresponding Aggregator LTIP Units to such Managing Directors representing such claim to AT Umbrella LLC LTIP Units. Andersen Group Inc. issued to Aggregator shares of Class B common stock equal in number to the maximum number of Class X Umbrella Units issuable upon exchange of such LTIP Units issued to Aggregator in exchange for the payment by Aggregator of the aggregate par value of the Class B common stock that is received.

AT Umbrella LLC LTIP Units are economically similar to stock options. Each LTIP Unit has a per-unit hurdle price, which is economically similar to the exercise price of a stock option. LTIP Units designated as "Catch-Up Units" are subject to a provision allowing their holder to receive additional distributions after satisfying the hurdle amount of the unit.

------

**ANDERSEN GROUP INC. AND SUBSIDIARIES**

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

Once the hurdle amount is surpassed, a catch-up adjustment ensures that the holder of the Catch-Up Unit receives distributions equivalent to what they would have received if the hurdle amount had not been applied, up to the agreed-upon cumulative amount. All LTIP Units are designated as Catch-Up Units.

LTIP Units generally vest 1/5th on each annual anniversary of the vesting commencement date over a five-year period, subject to the recipient's continuous service as an employee of the Company or one of its subsidiaries.

The following table summarizes information around AT Umbrella LLC LTIP Units:

---

| | |
|:---|:---|
| | **Number of Units** |
| **Outstanding as of December 31, 2025** | **976,563** |
| Granted |  |
| Exercised |  |
| Forfeited |  |
| **Outstanding as of March 31, 2026** | **976,563** |

---

The fair value of the LTIP Units was based on the fair value of a share of Class A common stock of Andersen Group Inc. at the time of grant, which equates to a weighted-average grant date fair value of $16.00 per unit. The LTIP Units granted in 2025 are subject to a hurdle amount of $16.00 per unit, which was specified at issuance and represents the threshold over which an LTIP Unit is allocated income or is entitled to distributions.

Total equity-based compensation expense for LTIP Units was approximately $0.9 million for the three months ended March 31, 2026, which is included in cost of services in the consolidated statement of operations. The unamortized compensation cost related to LTIP Units of $12.9 million as of March 31, 2026 is expected to be recognized over a weighted-average period of approximately 4.7 years.

*Class X Aggregator Units*

In connection with the Reorganization Transactions described in Note 1, Andersen Tax LLC incurred compensation expenses as a result of the exchange of common units and PIUs of the Management Holdcos for new Class X Aggregator Units with Managing Directors of Andersen Tax LLC, of which a portion of the new interests are subject to vesting conditions. These Class X Aggregator Units generally vest 1/5th on each annual anniversary of their vesting commencement dates.

The following table summarizes information around Class X Aggregator Units subject to vesting conditions:

---

| | |
|:---|:---|
| | **Number of Units** |
| **Outstanding as of December 31, 2025** | **44745250** |
| Granted |  |
| Vested | (232500) |
| Forfeited | (340000) |
| **Outstanding as of March 31, 2026** | **44172750** |

---

The portion of units subjected to service-based vesting conditions results in incremental compensation expense to be recognized over the requisite service period. The Company incurred $41.1 million of compensation expense for Class X Aggregator Units for the three months ended March 31, 2026, of which $37.5 million was recognized in cost of services and $3.6 million was recognized in sales, general and administrative expenses on the consolidated statement of operations. The unamortized compensation cost related to Class X Aggregator Units of $662.2 million as of March 31, 2026 is expected to be recognized over a weighted-average period of approximately 4.5 years. The grant date weighted average fair value associated with all Class X Aggregator Units was $16.00 per unit. The overall value of the Class X Aggregator Units was derived from the value of the Class A common stock for which the units may be exchanged.

**Note 14. Earnings Per Share**

Due to the impact of the Reorganization Transactions, the Company's capital structure for the period prior to the IPO is not comparable. As a result, the presentation of earnings per share for the periods prior to such transactions is not meaningful and only earnings per share for the period subsequent to the IPO is presented herein.

The Company computes earnings per share ("EPS") of Class A common stock. Basic EPS is computed by dividing net income attributable to common stockholders by the weighted average number of shares of Class A common stock outstanding. The Company's Class B common stock and RSUs are nonparticipating securities because holders are not entitled to dividends or dividend equivalent payments.

For the calculation of diluted EPS, net income attributable to common stockholders for basic EPS is adjusted by the effect of dilutive securities. Diluted EPS attributable to common stockholders is computed by dividing the resulting net income attributable to common stockholders by the weighted-average number of common stock outstanding, adjusted to give effect to dilutive elements including RSUs and convertible Class X Umbrella Units and LTIP Units to the extent these are dilutive.

The following table presents the calculation of basic and diluted earnings per share for the three months ended March 31, 2026 (in thousands, except share and per share amounts):

---

| | |
|:---|:---|
| **Numerator:** | |
| Net income | $17738 |
| Net income attributable to noncontrolling interest | 17244 |
| Net income attributable to Andersen Group Inc. stockholders, basic | $494 |
| Net income attributable to Andersen Group Inc. stockholders, diluted | $494 |
| **Denominator:** |  |
| Weighted average number of shares of Class A common stock outstanding, basic | 12650000 |
| Effect of dilutive RSUs | 1768886 |
| Effect of dilutive LTIP Units | 395835 |
| Weighted average number of shares of Class A common stock outstanding, diluted | 14814721 |
| **Earnings per share:** |  |
| Earnings per share attributable to Class A common stockholders, basic | $0.04 |
| Earnings per share attributable to Class A common stockholders, diluted | $0.03 |

---

The effect of the Company's potentially dilutive Class X Umbrella Units were not included in the calculation of diluted earnings per share as the effect would be anti-dilutive. At March 31, 2026, 97,850,000 Class X Umbrella Units with a potentially dilutive impact were outstanding.

**Note 17. Income Taxes**

Andersen Group Inc. is taxed as a C corporation and is subject to U.S. federal, state and local income taxes on its share of allocable partnership income. Andersen Group Inc.'s sole material asset is its ownership in AT Umbrella LLC, which is a limited liability company that is taxed as a partnership for U.S. federal and certain state and local income tax purposes. AT Umbrella LLC's allocable share of taxable income and related tax credits, if any, are passed through to its members, including Andersen Group Inc., and are included in the members' tax returns.

Prior to Andersen Group Inc.'s investment in AT Umbrella LLC, the Company was a multi-member limited liability company taxed as a partnership and generally not subject to U.S. federal and state taxes. However, certain state and local jurisdictions impose an entity level income tax and these amounts are reflected as income taxes in the consolidated financial statements. Each member of the limited liability company is responsible for reporting and paying income tax on their share of income or loss to the extent required by federal and state income tax regulations.

In calculating the provision for interim income taxes in accordance with ASC Topic 740, Income Taxes, an estimated annual effective tax rate is applied to year-to-date ordinary income. At the end of each interim period, the Company estimates the effective tax rate expected to be applicable for the full fiscal year. The Company also records the tax impact of certain discrete, unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effects of changes in tax laws or rates on deferred tax balances, in the interim period in which they occur.

For the three months ended March 31, 2026 and 2025, the Company recorded an income tax provision of $2.8 million and $4.1 million, respectively on pre-tax income of $20.6 million and $54.7 million respectively.

The Company's effective tax rate for the three months ended March 31, 2026 was 13.7% compared to 7.5% for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2026 differed from the U.S. statutory rate of 21% primarily due to non-controlling interest as Andersen Group Inc. is only subject to income tax on its allocable share of partnership income from AT Umbrella LLC and state and local income taxes. The effective tax rate for the three months ended March 31, 2025 differed from the U.S. statutory rate of 21% primarily related to income not subject to entity level tax as the Company is taxed as a partnership, compensation expense recorded for accounting purposes related to profit interest units that are not deductible for tax purposes and certain state and local entity level taxes.

The Company regularly assesses the need for a valuation allowance related to its deferred tax assets. In making such assessment, the Company considered both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on a weighing process of available evidence, whether it is more-likely-than-not that

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

its deferred tax assets will not be realized. As of March 31, 2026, the Company continued to conclude that substantially all of its investment in AT Umbrella LLC is not realizable on a more-likely-than-not basis as the investment in AT Umbrella LLC is capital in nature.

**Note 18. Segment Reporting**

The Company conducts business as a single operating segment for its range of tax, valuation, financial advisory, and related consulting services. In reaching this conclusion, management considers the definition of the Chief Operating Decision Maker ("CODM"), how the business is defined by the CODM, the nature of the information provided to the CODM, and how that information is used to make operating decisions, allocate resources, and assess performance. The Company's CODM is the chief executive officer. The results of operations provided to and analyzed by the CODM are at the consolidated level which is the level that the CODM manages the business, allocates resources, makes key resource decisions, and assesses performance.

The key measure of segment profit and loss that the CODM uses to allocate resources and assess performance is the Company's net income or loss. The measure is used to benchmark the Company's results against forecasts. The table below shows a reconciliation of the Company's net income, including the significant expense categories regularly provided to and reviewed by the CODM, as computed under U.S. GAAP to the Company's total net income or loss in the unaudited condensed consolidated statements of operations (in thousands):

(1)Non-personnel and other operating costs primarily include the provision for credit losses and costs such as occupancy, business development, training, recruiting, and annual discretionary bonus compensation.

Assets provided to the CODM are consistent with those reported on the consolidated balance sheets with particular emphasis on the Company's available liquidity, including its cash, cash equivalents, and financial instruments owned, reduced by current liabilities.

Substantially all long-lived assets are maintained in, and the majority of income and losses are attributable to the United States of America.

**Note 19. Subsequent Events**

*Capital Account and Holdover Notes*

After the reporting date, in April 2026, the Company pre-paid its Capital Account Notes and Holdover Note obligations in the amount of $19.4 million and made a quarterly scheduled payment of $4.2 million, see Note 9, "Long-Term Debt-Capital Account Notes" and Note 9, "Long-Term Debt-Holdover Note" for additional information.

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

*Distributions*

After the reporting date of March 31, 2026, the Company effected distributions to its pre-IPO owners in an aggregate amount of $12.8 million, related to undistributed capital and allocated income declared payable prior to the Reorganization Transactions. The Company also made a tax distribution to Aggregator in the amount of $11.2 million.

*Inorganic Growth*

In May 2026, the Company announced it closed the acquisition of tax firms in Ireland and New Zealand, a tax firm and a consulting firm in Nigeria, and a tax firm and a law firm in Uruguay, expanding its presence across key developed and high-growth markets as it continues to scale its global platform.

Due to the limited amount of time since the dates of the closed acquisitions, the initial accounting for the business combinations is incomplete, and therefore the Company is unable to disclose the information required by ASC 805, Business Combinations. The Company will include relevant disclosures as required in the second quarter of 2026.

In addition, Andersen signed agreements for the acquisition of a tax firm in Switzerland and a business combination in Canada, both expected to close in the third quarter of 2026, subject to the satisfaction of certain closing conditions.

**Overview**

We are a leading provider of independent tax, valuation and financial advisory services to individuals, wealthy families, businesses and institutional clients in the United States. From our roots as a tax advisory firm, we have strategically expanded our business to build an integrated platform of service offerings that enables us to solve our clients' most complex challenges. We have achieved this by delivering market-leading technical expertise combined with practical advice, supported by our unique firm culture, integrated services offerings and our relationship with Andersen Global, a Swiss association of over 300 member and collaborating firms.

Refer to the Annual Report on Form 10-K for the year ended December 31, 2025 for further discussion of our business and strategies as well as factors that currently impact our operations.

**Recent Developments**

***Inorganic Growth Opportunities***

Andersen's relationships with over 400 Andersen Global and Andersen Consulting member and collaborating firms provide opportunities for domestic and international expansion through closer partnerships and, future acquisitions and future business combinations. In May 2026, the Company announced it closed the acquisition of tax firms in Ireland and New Zealand, a tax firm and a consulting firm in Nigeria, and a tax firm and a law firm in Uruguay, expanding its presence across key developed and high-growth markets as it continues to scale its global platform. In addition, Andersen signed agreements for the acquisition of a tax firm in Switzerland and a business combination in Canada, both expected to close in the third quarter of 2026, subject to the satisfaction of certain closing conditions.

***Executive Summary***

Revenue for the three months ended March 31, 2026 was $240.7 million, representing 15.7% year-over-year growth, driven by strong execution and continued demand across our core markets, as compared with $208.1 million of revenue for the three months ended March 31, 2025. Growth in 2026 was supported by client growth, higher volume and service line expansion. There were no large one-time 2026 revenue items, and all of our service lines grew revenues in the three months ended March 31, 2026 as compared with the three months ended March 31, 2025.

**Key Financial and Operational Metrics**

We monitor the following key financial and business metrics to evaluate our business, measure our performance and make strategic decisions:

***Revenue and Components of Revenue***

We generate our revenue from providing tax and financial advisory services to our clients. During the three months ended March 31, 2026 and 2025, the substantial majority of our revenue was generated on a time and materials basis and, to a lesser extent, on a fixed fee basis and contingent fee basis. In the future, our revenue and profitability could vary materially depending on changes in the nature of services provided, as well as the stage of performance at which the right to receive fees is finally determined. We provide services in four primary areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Private Client Services***. We provide comprehensive tax and financial services for individuals and families, addressing complex client matters such as multigenerational wealth, charitable giving and trust and estate planning.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Business Tax Services***. We offer a broad range of scalable, integrated tax-related consulting and compliance services for businesses, helping organizations with managing their tax planning, compliance and reporting needs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Alternative Investment Funds***. We deliver comprehensive tax and financial-related services for alternative investment funds, including family offices, funds of funds, hedge funds, private equity funds, venture capital funds and real estate investment trusts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Valuation Services***. We provide clients with independent valuation expertise that helps clients navigate tax laws and regulations and comply with regulatory requirements.

During the three months ended March 31, 2026, our revenue increased by 15.7% to $240.7 million from $208.1 million during the three months ended March 31, 2025. Revenue consists of professional services revenue and reimbursable expenses, which primarily include travel and out-of-pocket costs that are billable to clients.

*Revenue by Service Line*

We have built a multidimensional independent advisory firm with the ability to provide differentiated services across tax and financial services to address our clients' most complex challenges. This is reflected in the revenue contribution of our services lines:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Private Client Services  | 51.2% | 50.1% |
| Business Tax Services | 33.5% | 34.4% |
| Alternative Investment Funds | 10.4% | 10.7% |
| Valuation Services | 4.9% | 4.8% |

---

The percentage of revenue by service line has largely remained stable over the past five years.

------

*Revenue by Geographic Region*

Since our founding, we have expanded our geographic reach across the United States, serving clients from 27 offices as of March 31, 2026. While our offices are primarily situated in major metropolitan areas, our expansive presence across the United States allows us to adapt to regional market fluctuations and capitalize on localized opportunities. Geographic revenue contribution is derived from the assigned office of each employee working on an engagement. This regional allocation typically aligns with the region in which the client is located, but in some cases, the client may be in a region different from the location of the office or employees.

Revenue by U.S. region was:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| East | 42.1% | 39.8% |
| Central | 16.4% | 17.0% |
| West | 41.5% | 43.2% |

---

***Clients***

Client groups will often comprise multiple client engagements with different entities or individuals, such as multiple subsidiaries of an entity, multiple principals within a single private equity fund or multiple individuals or trusts within a single wealthy family. Across our client groups, we had over 18,970 client engagements during the three months ended March 31, 2026, representing an increase of approximately 2% from the over 18,600 client engagements we served during the three months ended March 31, 2025.

Our clients are distributed across a substantial number of individuals, wealthy families and trusts and business enterprises within a wide range of industries, including financial services, consumer products, healthcare, hospitality, manufacturing, pharmaceutical and biotech, private equity, real estate, technology and venture capital. By serving a diverse range of clients across a diverse range of industries, we believe we can capitalize on growth opportunities in expanding sectors while offsetting potential slowdowns in others.

***People Metrics***

Compensation represents the largest portion of our operating expenses. As a result, we monitor our total number of employees and growth in employees:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Managing Directors | 323 | 312 |
| Non-Managing Directors | 1948 | 1897 |
| **Total Employees** | 2271 | 2209 |

---

Our workforce, which excludes temporary staff, consists of predominantly client serving professionals, and grew to 2,271 total employees as of March 31, 2026. During the three months ended March 31, 2026, attrition, excluding involuntary terminations, increased by 1.5% to 15.7% from 14.2% during the three months ended March 31, 2025.

As of March 31, 2026, our workforce had a balanced distribution of tenure, reflecting a blend of experienced professionals and newer talent. Our 2,271 total employees included 323 Managing Directors as of March 31, 2026.

**Non-GAAP Financial Measures**

We use certain non-GAAP financial measures to supplement our financial measures prepared in accordance with accounting principles generally accepted in the United States ("GAAP"), which include EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and Adjusted Net Income Margin ("Non-GAAP Financial Measures"). We believe that the Non-GAAP Financial Measures, when taken collectively, may be helpful to investors because they provide consistency and comparability with past financial performance. We also believe that the Non-GAAP Financial Measures can enhance an investor's understanding of our financial and operating performance from period to period, because they exclude certain items relating to income tax expense, interest, depreciation and amortization, equity-based

------

compensation, and transaction costs which are not necessarily reflective of our ongoing operations and performance. However, the Non-GAAP Financial Measures are presented for supplemental informational purposes only, have limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Some of the limitations of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin include that they exclude certain tax payments that may reduce cash available to us, do not reflect any cash capital expenditure requirements for the assets being depreciated and amortized that may have to be replaced in the future, and do not reflect changes in, or cash requirements for, our working capital needs. Some of the limitations of Adjusted Net Income and Adjusted Net Income Margin include that they exclude the impact of expenses related to transaction activities, certain equity restructuring expenses and certain components of equity-based compensation.

Other companies, including companies in the professional services industry, may calculate similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, any of which could reduce the usefulness of our Non-GAAP Financial Measures as tools for comparison. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these Non-GAAP Financial Measures to their most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

The following table summarizes the Non-GAAP Financial Measures (along with the most directly comparable GAAP measures) for the periods indicated:

---

(1)These are non-GAAP financial measures. See below for a reconciliation to the most directly comparable GAAP financial measure.

***Adjusted Net Income and Adjusted Net Income Margin***

We define Adjusted Net Income as net income plus expenses related to transaction activities, including costs related to planned mergers, acquisitions, and business combinations, non-recurring equity restructuring costs and non-cash equity-based compensation expense associated with equity interests that were issued in anticipation of, and in connection with, the IPO. We define Adjusted Net Income Margin as Adjusted Net Income divided by revenue. We believe Adjusted Net Income and Adjusted Net Income Margin enhance an investor's understanding of our financial and operating performance because they exclude transaction-related costs allowing for greater transparency into what measures we use in operating our business and measuring our performance. In addition, these measures enable comparison of financial trends and results

(1)Transaction costs include certain legal, accounting and consulting costs incurred related to planned mergers, acquisitions, and business combinations during the three months ended March 31, 2026 and certain legal, accounting and consulting costs incurred for public company readiness not eligible for capitalization and related to the planned restructuring during the three months ended March 31, 2025.

(2)Equity-based compensation expense associated with the vesting of Class X Aggregator Units consists of non-cash expenses associated with the vesting of Class X Aggregator Units, which were part of the Reorganization Transactions and described in Note 13, "Equity-based Compensation—Class X Aggregator Units" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report. We recognized $37.5 million of non-cash equity-based compensation expense associated with Class X Aggregator Units in cost of services and $3.6 million in sales, general and administrative expense during the three months ended March 31, 2026.

***EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin***

We define EBITDA as net income plus income tax expense, interest expense, and depreciation and amortization less interest income. We define Adjusted EBITDA as EBITDA with adjustments to exclude results from expenses related to transaction activities, including costs related to planned mergers, acquisitions, and business combinations and non-cash equity-based compensation expense associated with equity interests that were issued in anticipation of, and in connection with, the IPO. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue.

------

(2)Equity-based compensation expense associated with the vesting of Class X Aggregator Units consists of non-cash expenses associated with the vesting of Class X Aggregator Units, which were part of the Reorganization Transactions and described in Note 13, "Equity-based Compensation—Class X Aggregator Units" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report. We recognized $37.5 million of non-cash equity-based compensation expense associated with Class X Aggregator Units in cost of services and $3.6 million in sales, general and administrative expense during the three months March 31, 2026.

**Components of Our Results of Operations**

***Revenue***

The substantial majority of our revenue is recognized on a time and materials basis. Each of our professionals is assigned an hourly billing rate based on several factors, such as classification, experience level, location, market conditions, area of expertise, and service line. Time related to the performance of all services is maintained in a time and billing system. However, we may enter into service arrangements that are not based on a time and materials basis, such as fixed price or contingent fee arrangements, although to date such arrangements have not represented a material portion of our revenue. Our engagements may also provide for adjustments, refunds, or discounts under specific circumstances that are reflected in the transaction price.

***Operating Expenses***

Our operating expenses consist of the following:

*Cost of Services*

Cost of services primarily consist of direct expenses related to the production of deliverables under client assignments. This includes personnel costs for revenue-generating personnel, such as wages, equity-based compensation, benefits and incentive compensation, and sub-consultant costs, software costs and an allocation of non-personnel costs such as occupancy costs.

*Sales, General and Administrative*

Sales, general and administrative expenses primarily consist of personnel costs such as wages, equity-based compensation, benefits and incentive compensation related to support and administrative functions, and non-personnel costs such as professional fees, business development, occupancy, advertising, recruiting and training costs.

*Equity-Based Compensation*

In connection with the IPO and the Reorganization Transactions, we incurred substantial equity-based compensation expense with respect to (1) RSUs and Aggregator LTIP Units that we granted in connection with the IPO, (2) the exchange of the profits interest units granted in 2025 for unvested Class X Aggregator Units as part of the Reorganization Transactions, and (3) the exchange of Management Holdco units for unvested Class X Aggregator Units as part of the Reorganization Transactions. We expect to incur equity-based compensation expense with respect to equity-based awards we intend to grant in the future, including RSUs under our equity incentive plan and Aggregator LTIP Units. Our equity-based compensation is described further in Note 13, "Equity-based Compensation" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report.

*Depreciation and Amortization*

Depreciation and amortization primarily consist of depreciation and amortization of our property and equipment, software and acquired intangible assets.

***Interest Income***

Interest income consists of interest earned on cash and cash equivalent balances, investments in held-to-maturity debt securities, and notes receivable from related parties.

------

***Interest Expense***

Interest expense consists primarily of interest related to the CA Notes and the HO Note. We expect to incur lower interest expense in the future related to the CA Notes and the HO Note as principal amounts are paid down.

***Other Income, Net***

Other income, net consists primarily of sublease income and license fee income.

***Income Tax Expense***

Income tax expense consists primarily of current and deferred income tax.

***Net Income Attributable to Noncontrolling Interest***

Net income attributable to noncontrolling interest reflects the income earned or loss incurred attributable to the equity interest Aggregator has in our AT Umbrella LLC subsidiary. See Note 1, "Organization and Business Description" and Note 2, "Summary of Significant Accounting Policies" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for further information. Net income attributable to Andersen Group Inc. represents the income attributable to the shareholders of Andersen Group Inc.

| Revenue | $240746 | $208067 | 15.7% |

---

Our revenue during the three months ended March 31, 2026 increased by $32.7 million, or 15.7%, to $240.7 million, compared to $208.1 million during the three months ended March 31, 2025. Revenue growth was broad-based across all service lines, driven by client additions, higher volume, and service line expansion during the three months ended March 31, 2026 compared to the three months ended March 31, 2025.

Our busiest periods typically align with U.S. tax filing deadlines, particularly the months leading up to April 15th for individual and corporate tax filings and the extension deadlines in October. During these peak times, we typically experience a substantial increase in client engagements and workload, which has historically driven an increase in billable hours and revenue in the first and third quarters of the year.

*Cost of services*

Our cost of services during the three months ended March 31, 2026 increased by $48.4 million, or 41.0%, to $166.4 million compared to $118.0 million during the three months ended March 31, 2025. The increase in cost of services was primarily attributable to $41.2 million in non-cash equity-based compensation in the first quarter of 2026 resulting from new Class X Umbrella Units, LTIP Units and RSUs granted in connection with the IPO and Reorganization Transactions. Other personnel costs increased by $7.3 million as our headcount scaled to meet higher demand for our services. Cost of

------

services as a percentage of revenue increased period-over-period from 56.7% during the three months ended March 31, 2025 to 69.1% for the three months ended March 31, 2026.

*Sales, general and administrative*

Our sales, general and administrative expenses during the three months ended March 31, 2026 increased by $12.6 million, or 35.8%, to $48.0 million compared to $35.4 million during the three months ended March 31, 2025. The increase was primarily related to equity-based compensation costs of $4.4 million resulting from grants of equity-based units in connection with the IPO in December 2025, as well as a $2.2 million increase in salaries and related expenses in connection with our increased headcount year-over-year. We also incurred $1.3 million in increased technology expenses as a result of additional software which was implemented to adhere to various regulatory requirements in connection with the IPO. Sales, general and administrative costs as a percentage of revenue increased period-over-period from 17.0% for the three months ended March 31, 2025 to 19.9% for the three months ended March 31, 2026.

*Depreciation and amortization*

Our depreciation and amortization expenses during the three months ended March 31, 2026 increased by $0.2 million or 8.5%, to $2.3 million compared to $2.1 million during the three months ended March 31, 2025. Depreciation and amortization costs as a percentage of revenue remained relatively consistent period-over-period at 0.9% compared to 1.0%.

Interest income during the three months ended March 31, 2026 increased by $0.7 million, or 56.6%, to $1.9 million, compared to $1.2 million during the three months ended March 31, 2025. The increase was primarily driven by increased interest from money market funds.

---

Interest expense for the three months ended March 31, 2026 was approximately $6.2 million, and was $0.1 million for the three months ended March 31, 2025. The increase was attributable to the CA Notes and HO Note incurred in connection with the IPO and Reorganization Transactions described in Note 1, "Organization and Business Description" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report.

---

For the three months ended March 31, 2026 and 2025, we recorded an income tax provision of $2.8 million and $4.1 million, respectively on pre-tax income of $20.6 million and $54.7 million respectively. Our effective tax rate for the three months ended March 31, 2026 was 13.7% compared to 7.5%, for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2026 differed from the U.S. statutory rate of 21.0% primarily due to non-controlling interest as Andersen Group Inc. is only subject to income tax on its allocable share of partnership income from AT Umbrella LLC and state and local income taxes. The effective tax rate for the three months ended March 31, 2025 differed from the U.S. statutory rate of 21.0% primarily related to income not subject to entity level tax as we were taxed as a partnership and compensation expense recorded for accounting purposes related to profit interest units that are not deductible for tax purposes and certain state and local entity level taxes.

As of March 31, 2026, our conclusion regarding the realizability of our US deferred tax assets did not change and we continued to conclude that substantially all of its investment in AT Umbrella LLC is not realizable on a more-likely-than-not basis as the investment in AT Umbrella LLC is capital in nature.

***Net Income Attributable to Noncontrolling Interest***

The net income attributable to the noncontrolling interest of AT Umbrella LLC for the three months ended March 31, 2026 was $17.2 million, which is 88.6% of the earnings of AT Umbrella LLC for the three months ended March 31, 2026.

**Liquidity and Capital Resources**

Historically, we have generated sufficient cash to fund our operations, capital expenditures and discretionary funding needs through cash generated from our operating activities. As of March 31, 2026, cash and cash equivalents were $206.8 million and investments in treasury securities were $5.1 million.

Our expected liquidity needs may be impacted by discretionary investments, acquisitions and business combinations that we could pursue in the future. However, we could raise additional funds through public or private debt or equity financings in the future to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchase, redeem or exchange shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay dividends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acquire businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expand geographically; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• invest in developing new services.

We believe that our existing cash and cash equivalents, cash flows from operations and the net proceeds from the IPO will be sufficient to meet our current and longer-term working capital, investments and other general corporate funding requirements. Substantially all of our cash is held in the United States where there are no significant regulatory restrictions or material tax effects on the free flow of funds among entities in our corporate structure.

Our working capital management primarily relates to trade accounts receivable, accounts payable, and incentive-based compensation and other assets typically related to activities in the normal course of our business operations. At any specific point in time, working capital is subject to many variables, including seasonality and the timing of cash receipts and payments.

***Tax Receivable Agreement***

In connection with the Reorganization Transactions, the Company entered into a Tax Receivable Agreement (TRA) with certain pre-IPO owners. Under the TRA, we are required to pay to Aggregator 85% of the cash tax savings, if any, that we realize or are deemed to realize as a result of (i) increases in tax basis of AT Umbrella LLC's assets resulting from

------

purchases or exchanges of Class X Umbrella Units for our Class A common stock and (ii) certain other tax benefits, including payments made under the TRA. The TRA includes assumptions that may result in payments exceeding actual tax savings.

These payment obligations are expected to be significant and could reduce the amount of cash available for general corporate purposes, negatively impacting our liquidity. In the event of insufficient cash resources, unpaid amounts will accrue interest until paid.

Our obligations under the TRA could have a material adverse effect on our financial condition and may limit our ability to deploy cash for other strategic purposes. We might need to incur debt to finance payments under the TRA to the extent our cash resources are insufficient and there can be no assurance that we will be able to finance our obligations.

We have not yet incurred a liability in connection with the TRA.

***Distributions***

During the three months ended March 31, 2026, we paid distributions to the Aggregator of $18.1 million related to members' tax obligations, members' undistributed capital and allocated income prior to the IPO and Reorganization Transactions.

The AT Umbrella LLC Agreement requires cash distributions to the holders of economic interests in AT Umbrella LLC (including holders of Class X Umbrella Units, LTIP Units, the CA Notes and the HO Note) for purposes of funding their (or in the case of Aggregator, its members') tax obligations in respect of the taxable income of AT Umbrella LLC that is allocated to them. During the three months ended March 31, 2026, AT Umbrella LLC paid distributions to Aggregator of $6.3 million in satisfaction of member tax liabilities.

***Promissory Notes***

In connection with the Reorganization Transactions, AT Umbrella LLC issued two types of promissory notes to Aggregator representing (1) the HO Note and (2) the CA Notes. The HO Note were issued at an initial principal amount of $162.3 million and accrues interest at 7.63% payable over eight years. The CA Notes were issued at an aggregate initial principal amount of $187.8 million and accrue interest between 6.31% to 7.50% payable over two to seven years. See Note 9, "Long-Term Debt" and Note 19, "Subsequent Events" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for further information.

***Credit Facility***

We maintain a $20.0 million revolving line of credit, which we refer to as the Credit Agreement, with JPMorgan Chase Bank, N.A., as successor-in-interest to First Republic Bank. The Credit Agreement is collateralized by substantially all of our assets. In February 2026, we amended the Credit Agreement to extend through June 2026. The extension also modified certain terms relating to covenant requirements.

As of March 31, 2026, the Credit Agreement included a sublimit of $5.0 million for standby letters of credit. Borrowings under the Credit Agreement bear interest at the Prime rate with a floor of 5.0%. As of each March 31, 2026 and December 31, 2025, we had outstanding standby letters of credit of $1.3 million. We had no cash borrowings under the Credit Agreement as of March 31, 2026 or December 31, 2025. Our outstanding letter of credit is subject to a commitment fee of 1.5% per annum.

The Credit Agreement includes certain financial and liquidity covenants, which require us to maintain a net after tax profit of not less than $1.00 each year; prohibit us from having certain indebtedness outstanding, subject to certain exceptions; require us to maintain unencumbered liquid assets (other than the security interest granted to the lender) equal to at least (i) the sum of all outstanding indebtedness under the Credit Agreement (collectively, the Liquidity Indebtedness) and (ii) 1.25 times the aggregate amount of all Liquidity Indebtedness; and prohibit us from loaning money to any person, subject to certain exceptions including loans to employees and to member firms of Andersen Global, so long as each such loan is on arm's length terms and (i) matures within seven years, and does not have an outstanding principal balance in excess of $1,000,000 individually or $5,000,000 in the aggregate for loans to employees and (ii) matures within eleven years and does not have an outstanding principal balance in excess of $10,000,000 individually or $15,000,000 in the

------

aggregate for loans to any member firm of Andersen Global. During the three months ended March 31, 2026 and 2025, the Company had no uncured events of default with respect to the financial covenants required by the Credit Agreement.

See Note 9, "Long-Term Debt" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for further information.

***Cash Flows for the Three Months Ended March 31, 2026 and 2025***

Cash flows from operating, investing and financing activities for the three months ended March 31, 2026 and 2025 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** | **Change** |
| | **2026** | **2025** | $**%** |
| | **($ in thousands)** | **($ in thousands)** | **($ in thousands)** |
| Net cash flows (used in) provided by operating activities | $(3867) | $11227 | (134.4)% |
| Net cash flows (used in) provided by investing activities | (395) | 8134 | (104.9) |
| Net cash flows used in financing activities | (39204) | (12136) | 223.0 |
| **Change in cash and cash equivalents** | $**(43466)** | $**7225** |  |

---

***Operating Activities***

Net cash flows used in operating activities were $3.9 million during the three months ended March 31, 2026 compared to net cash flows provided by operating activities of $11.2 million during the three months ended March 31, 2025, a decrease of $15.1 million. The decrease was driven by a decrease in net income during the three months ended March 31, 2026 to $17.7 million compared to $50.6 million during the three months ended March 31, 2025, which was offset by net inflows from non-cash equity based compensation of $45.6 million for the three months ended March 31, 2026. The decrease in net cash flows was also driven by increased outflows from operating assets and liabilities, primarily attributable to an increase in accounts receivable of $91.4 million for the three months ended March 31, 2026 due to revenue growth compared to an increase in accounts receivable of $64.0 million during the three months ended March 31, 2025.

***Investing Activities***

Net cash flows used in investing activities were $0.4 million during the three months ended March 31, 2026 compared to net cash provided by investing activities of $8.1 million during the three months ended March 31, 2025, a decrease of $8.5 million. The decrease was primarily driven by a decrease in proceeds from held-to-maturity debt securities due to the lower balances carried in these investments during the three months ended March 31, 2026.

***Financing Activities***

Net cash flows used in financing activities were $39.2 million during the three months ended March 31, 2026 compared to $12.1 million during the three months ended March 31, 2025, an increase of $27.1 million. Distributions increased during the three months ended March 31, 2026 to $24.4 million compared to $11.3 million during the three months ended March 31, 2025 due to an increase in distributions paid to Aggregator after the Reorganization Transactions and distributions paid to Aggregator in satisfaction of member tax liabilities. The increase was also driven by principal payments of $13.6 million on the CA Notes and the HO Note during the three months ended March 31, 2026.

**Critical Accounting Estimates**

Our critical accounting estimates are disclosed in the Critical Accounting Estimates section in Part II, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the year ended December 31, 2025. Since December 31, 2025, there have been no material changes to our critical accounting estimates.

**Contractual Obligations and Commitments**

***Operating Leases***

Our operating lease commitments include corporate office space. As of March 31, 2026, we had fixed lease payment obligations of $144.2 million, with $6.9 million to be paid during the remainder of 2026 and the remainder thereafter.

***Andersen Global Commitments***

Management of Andersen Global has established a program to allocate certain global management, business development and other costs to its member firms. We fund these costs on behalf of Andersen Global and allocate a portion to be reimbursed by non-U.S. member firms. Our sales, general and administrative expenses in the unaudited condensed consolidated statements of operations include amounts for our share of cost allocations for Andersen Global with respect to global business development initiatives. As of March 31, 2026 and December 31, 2025, amounts due from member firms related to the program included in prepaid expenses and other current assets were $5.2 million and $4.3 million, respectively, and amounts due to member firms related to the program included in other current liabilities were $0.8 million and $0.6 million, respectively. See Note 15, "Transactions with Related Parties—Andersen Global Commitments" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for additional details.

***Other Commitments***

We are party to an agreement to use certain professional services training facilities (the Training Center Agreement) for a limited number of days per year. The minimum future commitment as of March 31, 2026 under the Training Center Agreement is approximately $5.2 million through 2030.

During 2024 and 2025, we signed commitments for software licenses for certain financial accounting systems and cloud hosting services. The contracts require minimum payments of $13.9 million through 2031.

See Note 16, "Commitments and Contingencies" to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for additional details on our commitments.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

There have been no material changes during the period covered by this Quarterly Report on Form 10-Q to the information disclosed in the Quantitative and Qualitative Disclosures About Market Risk section in Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the Securities and Exchange Commission on March 27, 2026.

**Item 4. Controls and Procedures**

**Evaluation of Disclosure Controls and Procedures**

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) that are designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As required by Rule 13a-15(b) under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2026, due to the material weaknesses described in Part II, "Item 9A "Controls and Procedures" in the 2025 Annual Report on Form 10-K, which continue to exist as of March 31, 2026. For additional information on our disclosure controls and procedures, reference the sections titled "Previously Reported Material Weaknesses in Internal Control Over Financial Reporting" and "Efforts to Address Previously Identified Material Weaknesses" in Part II, Item 9A "Controls and Procedures" of the 2025 Annual Report on Form 10-K.

***Changes in Internal Control Over Financial Reporting***

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

***Emerging Growth Company Status***

We are an emerging growth company, as defined in Section 2(a) of the Securities Act of 1933, as amended, and therefore are not required to provide an attestation report of our independent registered public accounting firm on internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002.

**PART II**

**Item 1. Legal Proceedings**

We are currently involved in, and may in the future be involved in, actual and threatened legal proceedings, claims, investigations and government inquiries arising in the ordinary course of our business that cover a wide range of matters, including errors and omissions, intellectual property, data privacy and data protection, torts, securities, labor and employment and contractual rights.

Although the results of the actual and threatened legal proceedings, claims, investigations and government inquiries in which we currently are involved cannot be predicted with certainty, we do not believe that there is a reasonable possibility that the final outcome of these matters will have a material adverse effect on our business or financial results. Regardless of the outcome, however, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, harm to our reputation and brand and other factors. For additional information on risks relating to litigation, reference Part I, Item 1A "Risk Factors—Risks Related to Our Business, Operations and Industry"—If we were to be held liable for alleged errors, omissions, illegal practices or other misconduct in providing our services to clients, our brand and reputation could be harmed and we could incur significant costs, which may exceed available insurance, if any, and which could harm our business" and "Risk Factors—Risks Related to Our Business, Operations and Industry"—Adverse judgments or settlements in legal disputes could result in monetary damages or injunctive relief that could damage our reputation and materially affect our results of operations" in the Company's 2025 Annual Report on Form 10-K.

**Item 1A. Risk Factors**

For a discussion of the risk factors affecting the Company, see Risk Factors in Part I, Item 1A of the 2025 Annual Report on Form 10-K.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds**

During the first quarter of 2026, we entered into a definitive agreement for a business combination with one member firm located in the strategically important area of Canada (the "Canada Transaction"). In May 2026, the Company announced it closed the acquisition of tax firms in Ireland and New Zealand, a tax firm and a consulting firm in Nigeria, and a tax firm and a law firm in Uruguay, expanding its presence across key developed and high-growth markets as it continues to scale its global platform ("Closed Transactions"). In addition, in May 2026, Andersen signed an agreement for the acquisition of a tax firm in Switzerland. Andersen's previously announced definitive agreement for a business combination in Canada and the Switzerland acquisition are both expected to close in the third quarter of 2026, subject to the satisfaction of certain closing conditions. As consideration for the Closed Transactions, we issued a total of 822,214 shares of Class A common stock, and expect to issue approximately 108,517 shares of Class A common stock for the Canada Transaction and we expect to issue approximately 32,566 shares of Class A common stock for the Switzerland acquisition (the "Consideration Shares"). The Consideration Shares were valued at $27.8 million for accounting purposes. The initial accounting for the Acquisitions and Business Combinations are incomplete as a result of the timing of these transactions. For more detail regarding these transactions, see Note 19 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. The sale and issuance of the Consideration Shares were made pursuant to transactions not involving an underwriter, and were not or will not be registered under the Securities Act of 1933, as amended (the "Securities Act"), as applicable, in reliance upon Regulation S of the Securities Act.

**Use of Proceeds from Public Offering of Class A Common Stock**

On December 18, 2025, we closed our IPO in which we issued and sold 12,650,000 shares of our Class A common stock, which included the exercise in full by the underwriters of their option to purchase 1,650,000 shares of Class A common stock at a public offering price of $16.00 per share. We received net proceeds of $188.2 million, net of underwriting discounts and commissions of $14.2 million, but before deducting offering costs of $9.9 million.

We currently intend to use the net proceeds from our IPO (including net proceeds received if the underwriters exercise their over-allotment option in full) to acquire a number of newly issued Class X Umbrella Units equal to the number of shares of Class A common stock issued in this offering from AT Umbrella LLC, at a purchase price per Class X Umbrella Unit equal to the initial public offering price of Class A common stock after deducting underwriting discounts and commissions. We currently intend to cause AT Umbrella LLC to use the proceeds it receives from the sale of Class X Umbrella Units to us to pay fees and expenses of approximately $9.6 million in connection with this offering and the

------

reorganization transactions and for other general corporate purposes. We also intend to cause AT Umbrella LLC to use the net proceeds for investments in technology, infrastructure, training and strategic acquisitions of, or investments in, other businesses or technologies that we believe will complement our current business and expansion strategies, although we do not currently have any agreements or commitments for any specific material acquisitions or investments. Pending other use of the net proceeds from this offering, we intend to invest the net proceeds of our IPO in a variety short-term, interest-bearing, investment-grade securities and government securities.

**Item 3. Defaults Upon Senior Securities**

None.

**Item 4. Mine Safety Disclosures**

None.

**Item 5. Other Information**

***Trading Arrangements***

During the quarter ended March 31, 2026, none of our directors or officers (as defined in Rule 16a-1(f) under the Exchange Act) adopted or terminated a "Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408 of Regulation S-K.

VIA EMAIL ONLY

Dear Susan:

This letter sets forth our agreement (the "Letter Agreement") regarding advisory services to be provided

by you to the Board of Directors of Andersen Group Inc. ("AGI") and your eventual service as a director on the Board of AGI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Effective as of July 16, 2025, you will act as an advisor ("Advisor") to the Board of Directors of AGI, a Delaware corporation until such time as you become a director ("Director") on the Board of AGI which shall occur by no later than July 1, 2026, unless either party provides the other with reasonable advance written notice of termination of your services as an Advisor or Director at any time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Remuneration as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a)&nbsp;&nbsp;&nbsp;&nbsp;As an Advisor to AGI, you shall receive 2,500 Profits Interest Units in the MD Entities (defined herein) ("PIUs"), 10% of which shall be in MD Management LLC ("Management") and 90% of which shall be in MD Investment LLC ("Investment"), which entities are indirectly owned by AGI (Management and Investment are collectively the "MD Entities"). Your obligation to purchase the PlUs shall be waived and the grant date of your PlUs shall be July 25, 2025<sup>1</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b)The PlUs shall be fully vested immediately.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c)As an Advisor and Director, you must retain 1/3 of your equity and you cannot convert more than 20% of your PIUs into AGI stock per year (on a cumulative basis).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d)Should you not become a Director by July 1, 2026, AGI or an affiliate shall have the right to repurchase 80% of your PIUs at book value. Should you terminate your services as an Advisor or Director, as applicable: (i) prior to July 1, 2027, AGI or an affiliate shall have the right to repurchase 60% of your PlUs at book value; (ii) prior to July 1, 2028, AGI or an affiliate shall have the right to repurchase 40% of your PlUs at book value; and (iii) prior to July 1, 2029, AGI or an affiliate shall have the right to repurchase 20% of your PlUs at book value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.With respect to your services to be rendered as an Advisor or Director, such services would include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a)Four Board meetings per year with two in person. For the initial year, all in person meetings will be in US. Likely locations would be either San Francisco, Chicago, Boston or New York. Over time, I would expect that we will have one meeting outside the US. All expenses for the meeting will be reimbursed by AGI and would include business class travel and lodging.

<sup>___________________________</sup>

<sup>1</sup> The grant of the PIUs to you shall be subject to your completion and return of all required documentation by no later than July 24, 2025.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b)I would expect that we may have a couple of additional calls per year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c)All in-person meeting, event and call requests will be made with reasonable advance notice, taking into account your other existing commitments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Mutual Confidentiality, including of Personal Information and Other Matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a)AGI and you each agree to cause all non-public information that the other or any officer, employee or designated agent of AGI or you or any of AGl's affiliates may learn about one another, including your personal life, finances, business arrangements or any similar information, to be kept confidential and not to, directly or indirectly, be disclosed, used, copied, published (including on any social media forum) or otherwise disseminated, in any such case without the prior written consent of AGI or you, as appropriate, except as required by applicable law, regulation or legal process. AGI and you also acknowledge and agree that any breach of this covenant would result in irreparable injury and damage to you and AGI, for which money damages would not provide an adequate remedy, and that, in addition to any other remedies you and AGI, respectively, may have at law or in equity, you and AGI, respectively, will be entitled to seek to have such provisions specifically enforced (without posting bond and without the need to prove damages) by any court of competent jurisdiction, including, without limitation, imposition of reasonable attorneys' fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b)AGI shall not (and shall not permit any of its personnel, agents or affiliates to) originate any publicity, news release or other public announcement relating to this Letter Agreement, its terms or the existence of an arrangement between the parties without your prior written consent. Notwithstanding the foregoing, Andersen shall have the right to use your name, biography and picture on the website of AGI or that of any of its affiliates, identifying you as an Advisor to AGI or a Director on its Board, as appropriate, so long as such information is limited to your position as an Advisor or Director, as appropriate, the name, biography, and picture, all to be provided by you.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c)You acknowledge that by virtue of receiving the PlUs, you shall be bound by Section 5.7 of the Limited Liability Company Agreements<sup>2</sup> of the MD Entities; provided, however, that it is acknowledged and agreed that none of the following activities shall be considered a violation of Section 5.7 of the Operating Agreements of the MD Entities: providing advisory or other similar services to any for-profit or not-for-profit organization that either (i) does not engage in any financial services or (ii) may be involved in financial services, but whose primary business is not in direct competition with any primary business of AGI or its affiliate Andersen Tax LLC (examples of which noncompetitive entities include, but are not limited to, investment or commercial banks, asset managers, hedge funds, NGOs, educational institutions and any governmental entity).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d)Subject to the foregoing provision (c), AGI further acknowledges and agrees that you may be engaged in or employed by any other business, trade, profession or other activity, including with respect to any other board positions you may hold.
