Andersen Group Reports Third Quarter Revenue Growth of 18.7% to $337.3 Million

Andersen Group Inc. (NYSE: ANDG) today reported strong financial results for the third quarter ended September 30, 2026, with revenue increasing 18.7% to $337.3 million, driven by continued double-digit growth and an expanding contribution from acquisitions. Revenue increased across all reported service lines and geographic regions, underscoring the strength of Andersen’s diversified business model and continued demand for its professional services. Consolidated net income determined in accordance with U.S. generally accepted accounting principles (“GAAP”) was $68.0 million, compared with $111.1 million in the third quarter of 2025.

The results reinforce Andersen’s strategy of combining sustained organic expansion with disciplined acquisitions to build a larger, more diversified global professional services platform. During the quarter, the Company continued expanding its international footprint and specialized capabilities while maintaining strong adjusted profitability and generating substantial operating cash flow. With eight acquisitions and business combinations completed through September 30, and an expanding base of client relationships and professional expertise, Andersen is positioning itself for continued growth. Reflecting this outlook, the Company introduced full-year 2027 revenue guidance of $1.275 billion to $1.325 billion, representing approximately 30% growth at the midpoint over its updated 2026 revenue guidance. These forward-looking estimates are subject to the risks and uncertainties described under “Special Note Regarding Forward-Looking Statements.”

These forward-looking estimates are subject to the risks and uncertainties described under “Special Note Regarding Forward-Looking Statements.”

Management Commentary

“Our third-quarter results demonstrate the strength of Andersen’s two complementary growth engines: strong organic expansion and disciplined acquisitions,” said Mark L. Vorsatz, Chairman and CEO of Andersen Group Inc. “We are not simply adding revenue through acquisitions, but building a more valuable global platform by combining specialized expertise, expanding client relationships and creating new opportunities for growth. We believe this strategy positions Andersen to deliver sustained revenue and earnings growth and long-term shareholder value.”

Financial Performance and Profitability

For the third quarter of 2026, Andersen reported consolidated GAAP net income of $68.0 million, compared with $111.1 million in the prior-year period. Net loss attributable to Andersen Group Inc. was $9.0 million, or $0.55 per basic and diluted Class A common share, reflecting the allocation of earnings to noncontrolling interests and the financial effects of the Company’s December 2025 IPO and related reorganization.

The year-over-year GAAP comparison reflects changes in the Company’s ownership structure and income tax treatment, along with equity-based compensation charges associated with its post-IPO compensation arrangements.

Equity-based compensation expense totaled $47.5 million in the third quarter, compared with $6.9 million in the prior-year period. For the first nine months, equity-based compensation totaled $141.4 million, compared with $136.5 million a year earlier. These non-cash expenses are excluded from the Company’s Adjusted EBITDA² and Adjusted Net Income² measures.

Adjusted Net Income² for the third quarter was $115.7 million, compared with $126.2 million in the prior-year quarter, a decline of 8.3%, reflecting higher post-reorganization income tax and interest expenses. For the first nine months, Adjusted Net Income³ increased 5.9% to $222.0 million from $209.5 million.

The Company’s underlying adjusted operating performance remained strong, with third-quarter Adjusted EBITDA³ increasing 18.8% year over year and its quarterly Adjusted EBITDA margin² remaining essentially unchanged at 45.8%.

Continuing Expansion Through Acquisitions

During the third quarter, Andersen completed acquisitions and business combinations in Canada and Switzerland, bringing the total number of completed transactions through September 30, 2026, to eight.

These transactions contributed $16.2 million in recognized revenue during the first nine months and added approximately 388 full-time equivalent employees. The $37.2 million in annual acquired revenue represents the acquired businesses’ revenue for the twelve months preceding their respective acquisitions and differs from revenue recognized in Andersen’s consolidated financial statements.

Beyond their direct financial contributions, the acquisitions are designed to expand Andersen’s geographic presence, deepen its professional expertise and create additional opportunities to serve clients across tax, consulting, legal, valuation and advisory services. The Company expects integration, cross-selling and increased operating scale to be important components of its long-term acquisition strategy.

Balance Sheet and Cash Flow

Andersen maintained a strong liquidity position at September 30, 2026, with $193.6 million in unrestricted cash and cash equivalents and net working capital of $301.5 million. Working capital is not a measure defined by GAAP and may not be comparable to similarly titled measures used by other companies.

Net cash provided by operating activities for the first nine months totaled $142.8 million, while capital expenditures were $13.7 million.

The Company had no borrowings outstanding under its $50 million revolving credit facility. Separately, it had $287.7 million of subordinated, related-party Capital Account Notes and Holdover Note obligations outstanding in connection with its IPO and reorganization.

Executive Summary

Revenue for the three months ended September 30, 2026 was $337.3 million, representing 18.7% year-over-year growth as compared to $284.3 million for the three months ended September 30, 2025. Revenue for the nine months ended September 30, 2026 was $795.7 million, representing 19.1% year-over-year growth as compared with $668.3 million for the nine months ended September 30, 2025. Revenue growth in 2026 was driven by strong execution and continued demand across our core markets, client growth, higher volume and service line expansion along with inorganic growth from acquisitions closed in the second and third quarters of 2026. There were no large one-time 2026 revenue items, and all of our service lines grew revenues year-over-year.

Key Financial and Operational Metrics

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

Inorganic Growth

Inorganic growth is an increasing part of the Company’s growth story and for this reason, we are providing additional disclosures:

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, future acquisitions and future business combinations. In the second quarter of 2026, the Company closed the acquisitions 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 the third quarter of 2026, Andersen closed the acquisition of a tax firm in Switzerland and a business combination in Canada. In the third quarter of 2026, the Company entered into definitive agreements for the acquisitions of a tax and legal firm in Mexico (“Andersen in Mexico”), a tax firm in the United Kingdom (“Andersen in the United Kingdom”), a valuation advisory firm in the Netherlands, an investment banking firm in South Africa and six consulting firms in the United States. In the fourth quarter of 2026, the Company entered into a definitive agreement for the acquisition of Andersen in Italy, a multidisciplinary corporate advisory law firm. All the transactions that signed in the third quarter of 2026 closed in the fourth quarter of 2026, except for the acquisitions of Andersen in Mexico, the investment banking firm in South Africa and Andersen in Italy, which are expected to close in the first quarter of 2027, subject to the satisfaction of certain closing conditions.

On November 10, 2026, the Company entered into definitive agreements for the acquisitions of a consulting firm in the United States, two consulting firms in India, a consulting firm in Spain and Andersen in Poland. All five transactions are expected to close in the first quarter of 2027, subject to the satisfaction of certain closing conditions.

Revenue

We generate our revenue from providing tax and financial advisory services to our clients. During the three and nine months ended September 30, 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:

• 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.

• Business 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.

• 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.

• 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 September 30, 2026, our revenue increased by 18.7% to $337.3 million from $284.3 million during the three months ended September 30, 2025. During the nine months ended September 30, 2026, our revenue increased by 19.1% to $795.7 million from $668.3 million during the nine months ended September 30, 2025. Revenue consists of professional services revenue and reimbursable expenses, which primarily includes contracted costs from third parties 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:

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 28 offices as of September 30, 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. In the second and third quarters of 2026, we also expanded internationally as part of our inorganic growth strategy.

Revenue by region was:

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. We evaluate our portfolio of client groups and client engagements on a periodic basis using a variety of quality-based metrics and may, from time-to-time, modify, consolidate or discontinue client relationships or client engagements.

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:

Our workforce, which excludes temporary staff, consists of predominantly client serving professionals, and grew to 2,930 total employees as of September 30, 2026. As of September 30, 2026, our annualized attrition rate, excluding international acquisitions, increased by 1.6 percentage points to 15.8% from 14.2% as of December 31, 2025.

As of September 30, 2026, our workforce had a balanced distribution of tenure, reflecting a blend of experienced professionals and newer talent. Our 2,930 total employees included 366 Managing Directors as of September 30, 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.

We have not provided a reconciliation of our full-year 2027 Adjusted EBITDA guidance to net income (loss), the most directly comparable GAAP financial measure, because we cannot do so without unreasonable efforts. We cannot reliably predict or estimate, with reasonable certainty, the amount or timing of certain items excluded from Adjusted EBITDA that would be included in net income (loss). These items include, among other items, non-cash equity-based compensation expense, which depends on the timing and amount of future grants and changes in the market price of our Class A common stock; transaction costs related to planned mergers, acquisitions and business combinations; and non-recurring equity restructuring costs. These items are uncertain, depend on factors outside management’s control and may be significant. As a result, we are unable to provide a reconciliation of forward-looking Adjusted EBITDA guidance or estimate the probable significance of the unavailable information, which could materially affect our future GAAP results.

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. 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 between periods.

In the second quarter of 2026, we revised our definition of Adjusted Net Income and Adjusted Net Income Margin to exclude all non-cash equity-based compensation, and in the last twelve months ended September 30, 2026, non-cash equity-based compensation expenses for LTIP Units and restricted stock units were added to conform to the current presentation. The change is intended to provide a more meaningful measure of our underlying operating performance by excluding equity-based compensation charges which are non-cash in nature and do not reflect our core operating results. The additional adjustments are consistent with our treatment of other equity-based compensation expenses and are intended to provide greater consistency in presentation. We applied the revised definition consistently to current and comparative periods, where applicable, to enhance period-to-period comparability. The impact of the revision is not material to previously disclosed figures.

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, non-cash equity-based compensation expense and non-recurring equity restructuring costs. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue.

In the second quarter of 2026, we revised our definition of Adjusted EBITDA and Adjusted EBITDA Margin to exclude all non-cash equity-based compensation, and in the last twelve months ended September 30, 2026, non-cash equity-based compensation expenses for LTIP Units and restricted stock units were added to conform to the current presentation. The change is intended to provide a more meaningful measure of our underlying operating performance by excluding equity-based compensation charges which are non-cash in nature and do not reflect our core operating results. The additional adjustments are consistent with our treatment of other equity-based compensation expenses and are intended to provide greater consistency in presentation. We applied the revised definition consistently to current and comparative periods, where applicable, to enhance period-to-period comparability. The impact of the revision is not material to previously disclosed figures.
