Andersen Group Inc. (NYSE: ANDG) grows 2025 revenue 14.6% but reports GAAP net loss

Rhea-AI Filing Summary

Andersen Group Inc. reported record 2025 results with full-year revenue of $838.7 million, up 14.6% from 2024, and fourth-quarter revenue of $170.3 million, up 19.6%. Growth was broad-based across all service lines, with only about $1.0 million from inorganic sources.

IPO- and restructuring-related costs drove a GAAP net loss of ($130.2 million) versus net income of $134.8 million in 2024, but 2025 Adjusted Net Income rose to $217.0 million and Adjusted EBITDA to $226.3 million, a 27.0% margin. The company completed a December IPO of 12,650,000 Class A shares at $16.00, generating net proceeds of $188.2 million and ending 2025 with cash and cash equivalents of $250.3 million. Client groups grew to 12,350 and employees to 2,296, while attrition remained around 14.2%. Andersen also initiated 2026 guidance and highlighted ongoing investments in platform expansion, technology, automation and AI.

Positive

• Robust underlying growth and margins: 2025 revenue increased 14.6% to $838.7 million and Adjusted EBITDA reached $226.3 million, expanding Adjusted EBITDA Margin to 27.0% from 19.5% in 2024.
• Strengthened liquidity via IPO: December’s IPO of 12,650,000 Class A shares at $16.00 generated $188.2 million in net proceeds, helping boost year-end cash and cash equivalents to $250.3 million.

Negative

• Large one-time charges and GAAP loss: Equity restructuring and IPO-related equity compensation drove a $130.2 million GAAP net loss and a stockholders’ deficit of $134.7 million for 2025.
• Higher obligations, including related-party debt and distributions: Notes payable to related parties reached $350.1 million (current and noncurrent), and $264.9 million of pre-IPO distributions were declared, with $52.7 million still payable at year-end 2025.

Insights

Equity research analyst

Strong revenue and cash from IPO offset by heavy one-time GAAP charges.

Andersen delivered solid underlying expansion: 2025 revenue grew 14.6% to $838.7 million, with Adjusted EBITDA of $226.3 million and a 27.0% margin. Client groups, large-account count and headcount all increased, indicating healthy demand and capacity.

GAAP results swung to a $130.2 million net loss, driven mainly by $193.2 million of equity restructuring costs and substantial equity-based compensation tied to the IPO. These charges also created a stockholders’ deficit, while new notes payable to related parties increased leverage.

The December IPO raised net proceeds of $188.2 million, lifting year-end cash and cash equivalents to $250.3 million. Management is emphasizing disciplined growth, acquisitions and technology and AI investments. Future filings discussing 2026 guidance and post-IPO capital deployment will be key to understanding the durability of current margin levels.

Exhibit 99.1

Andersen Reports Record Fourth-Quarter and Full-Year 2025 Financial Results and Initiates 2026 Guidance

San Francisco, Mar. 17, 2026 — Andersen Group Inc. (NYSE: ANDG) today released financial results for the fourth quarter and full year ended December 31, 2025.

Andersen delivered strong top-line growth in 2025, with full-year revenue of $838.7 million, up 14.6% from $731.6 million in 2024. Fourth-quarter revenue of $170.3 million grew 19.6% year-over-year, compared with $142.4 million in the prior year period. Revenue growth was broad-based across all service lines, driven by customer additions, higher volume, and service line expansion. No large one-time items contributed to 2025 revenue. Total inorganic revenue for full-year 2025 amounted to approximately $1.0 million. Expenses related to the initial public offering, including equity restructuring costs and certain components of equity-based compensation led to a (net loss) for full-year 2025 of ($130.2) compared with net income of $134.8 million in 2024. Adjusted net income for the full-year 2025 was $217.0 million as compared with $136.4 million in 2024.

• Record Fourth Quarter: Andersen delivered a robust fourth quarter, driven by strong demand across core services, with consistent growth in the Tax practice and accelerating momentum in Consulting and Global Mobility.

• Fourth-Quarter 2025 Revenue: $170.3 million, up 19.6% compared with $142.4 million in fourth-quarter 2024.

• Full-Year 2025 Revenue: $838.7 million, up 14.6% compared with $731.6 million in prior year.

• 2026 Guidance: Revenue expected to be approximately $955 million to $970 million, a growth rate of approximately 14% to 15%, including inorganic revenue of approximately $33 million; Adjusted EBITDA projected at $213 million to $220 million with margins of approximately 22% to 23%. 

• Strategic Investment Focus: 2026 will reflect continued investment in talent, technology, automation, AI, and integration of firms to be acquired during the year, resulting in an anticipated net loss and negative EPS for the full year.

• Long-Term Growth: Positioned for sustained revenue growth and expanding margins, supported by a large addressable market, strong competitive positioning, scalable operating model, and selective inorganic expansion.

• Commitment to Shareholder Value: Maintaining flexibility to deploy capital strategically to strengthen and expand the multi-dimensional platform, and enhance long-term shareholder value.

Mark L. Vorsatz, Global Chairman and CEO of Andersen, said:

“Our fourth quarter capped a record year for the firm, and underscores the strength of our global, multi-dimensional platform and the continued demand for high-value advisory services. We are entering 2026 with strong momentum, and a clear focus on disciplined growth – investing in the expansion of our platform, integrating high-quality firms across key markets, and deploying technology, automation and AI to enhance efficiency and scale our services. These investments position us to further strengthen our market leadership while driving sustained revenue growth and increased profitability over time.”

Initial Public Offering

On December 18, 2025, we completed our initial public offering (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. 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.

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:

		Year Ended December 31,
		2025 (Unaudited)				2024				2023
Revenue:
Revenue (in thousands)		$	838,692			$	731,593			$	639,111
Clients:
Client groups			12,350				11,700				10,700

People Metrics:
Employees			2,296				2,187				2,082
Attrition rate			14.2	%			14.1	%			11.0	%

Revenue Components

We generate our revenue from providing tax and financial advisory services to our clients. During 2025, 2024, and 2023, 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.

2

• 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.

• 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 2025, our revenue increased by 14.6% to $838.7 million from $731.6 million during 2024. During 2024, our revenue increased by 14.5% to $731.6 million from $639.1 million during 2023. 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

The following table shows the revenue contribution of our services lines:

		Year Ended December 31,
		2025 (Unaudited)				2024				2023
Private Client Services			51.5	%			49.8	%			50.2	%
Business Tax Services			34.8				35.7				35.4
Alternative Investment Funds			8.7				9.5				9.3
Valuation Services			5.0				5.0				5.1

Revenue by Geographic Region

Since our founding, we have expanded our geographic reach across the United States, serving clients from 26 offices as of December 31, 2025. 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:

		Year Ended December 31,
		2025 (Unaudited)				2024				2023
East			38.9	%			37.2	%			36.9	%
Central			19				18.5				18
West			42.1				44.3				45.1

Clients

During the year ended December 31, 2025, we performed services for over 12,350 client groups across the United States, representing an increase of approximately 5.6% from over 11,700 client groups during 2024. 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 22,450 client engagements in 2025, representing an increase of 10.6% from the over 20,300 client engagements we served in 2024.

During the year ended December 31, 2025, we had 687 client groups that generated over $250,000 in revenue, as compared to 629 such client groups in 2024. We attribute this growth to strong performance in service delivery, cross-selling services, leveraging our relationships with Andersen Global firms, and client satisfaction initiatives.

Our revenue is also dispersed across a broad range of client groups with no single client group accounting for more than 1% of revenue in 2025 and 2024. Our top 10 client groups accounted for approximately 5% of revenue in each of 2025 and 2024.

People Metrics

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

		Total Employees				Growth Rate				Attrition Rate
Year Ended December 31, 2025 (Unaudited)			2,296				5.0	%			14.2	%
Year Ended December 31, 2024			2,187				5.0				14.1
Year Ended December 31, 2023			2,082				20.2				11.0

Our workforce, which excludes temporary staff, consists of predominantly client serving professionals, and grew to 2,296 total employees as of December 31, 2025, compared to 2,187 as of December 31, 2024. Attrition, excluding involuntary terminations, was 14.2% in 2025, a slight decrease from our 5-year average of approximately 15%.

As of December 31, 2025, our workforce had a balanced distribution of tenure, reflecting a blend of experienced professionals and newer talent. Our 2,296 total employees included 319 Managing Directors as of December 31, 2025.

Non-GAAP Financial Measures

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

Adjusted EBITDA Margin (unaudited)(1)			27.0	%			19.5	%			19.7	%

(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 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 between periods. The following table reflects the reconciliation of net (loss)/income to Adjusted Net Income and Adjusted Net Income Margin for each of the periods indicated:

(1) Transaction costs include certain legal, accounting and consulting costs incurred for public company readiness not eligible for capitalization and related to the restructuring and amounts incurred in advance of planned mergers and acquisitions.

(2) Equity-based compensation expense associated with pre-IPO profits interest unit grants consists of non-cash compensation costs associated with the grants of profits interest units. These units were fully vested upon issuance and therefore a one-time expense was recognized in 2025. We recognized $104.5 million of non-cash equity-based compensation expense associated with pre-IPO profits interest units in cost of services and $32.0 million in sales, general and administrative expense during the year ended December 31, 2025.

(3) 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. We recognized $9.7 million of non-cash equity-based compensation expense associated with Class X Aggregator Units in cost of services and $0.5 million in sales, general and administrative expense during the year ended December 31, 2025.

(4) In connection with the Reorganization Transactions, we incurred certain equity restructuring expenses as a result of the exchange of historical equity interests of the Management Holdcos for new Class H Aggregator Units and/or the combination of Class X Aggregator Units and Member Notes.

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 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 EBITDA Margin as Adjusted EBITDA divided by revenue. The following table is a reconciliation of net (loss) / income to EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin for each of the periods indicated:

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 (collectively, “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, restructuring costs 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.

8

Additionally, we have relied upon the exception in Item 10(e)(1)(i)(B) of Regulation S-K and have not reconciled forward-looking Adjusted EBITDA to its most directly comparable U.S. GAAP measure, net income or loss, because we cannot predict with reasonable certainty the ultimate outcome of certain components of such reconciliations, including market-related assumptions and interest rate changes that are not within our control, or others that may arise, without unreasonable effort. For these reasons, we are unable to assess the probable significance of the unavailable information, which could materially impact the amount of future net income or loss.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this Press Release. These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including the risk that: our future results, and the business activities of our clients, may be adversely affected by volatile, negative or uncertain economic and geopolitical conditions; an inability to respond to the evolving technological environment could materially affect our results of operations; the development and use of AI could harm our business, damage our reputation or give rise to legal or regulatory action; we may be not able to maintain or increase our historical growth, or effectively manage future growth; we may not be able to generate or maintain client demand for our services; we may be unable to expand our service offerings; our success depends substantially on the continued services of our CEO, executive team, Managing Directors and other key personnel; we may be unable to maintain our reputation, brand and firm culture; we may be unable to recruit, train and retain qualified professionals, and to staff client engagements; we may be subject to cybersecurity incidents or attacks; we may be held liable for alleged errors in providing our services; we may be unable to identify potential acquisitions or successfully integrate or manage completed acquisitions, and those risks, uncertainties, and assumptions described in the section titled “Risk Factors” in our prospectus filed with the SEC on December 17, 2025, in Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended

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 Press Release may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.
