2025 Third Quarter Results

Consolidated net revenue increased 15.9%, or $44.3 million, to $322.8 million in the 2025 third quarter compared to consolidated net revenue of $278.6 million in the 2024 third quarter (up 14.2%, or $39.7 million on a constant currency basis). The revenue increase was driven by year-over-year growth in each of the Company’s lines of business — Executive Search, On-Demand Talent, and Heidrick Consulting.

2025 third quarter net income was $17.6 million and diluted earnings per share was $0.83 compared to net income of $14.8 million and diluted earnings per share of $0.71 in the 2024 third quarter.

The higher revenue versus the year-ago period was driven by increases of 20.8% in the Americas (up 20.7% on a constant currency basis), 18.0% in Europe (up 12.1% on a constant currency basis), partially offset by a decrease in Asia Pacific of 3.9% (down 3.1% on a constant currency basis) when compared to the 2024 third quarter.

Adjusted EBITDA increased $6.5 million, or 12.8%, to $57.2 million in the 2025 third quarter compared to $50.7 million in the 2024 third quarter, and 2025 third quarter adjusted EBITDA margin was 23.9% compared to 24.8% in the 2024 third quarter.

Adjusted EBITDA was $2.8 million in the 2025 third quarter compared to $1.8 million in the 2024 third quarter, and Adjusted EBITDA margin was 5.6% compared to 3.8% in the 2024 third quarter.

Heidrick Consulting net revenue increased $4.9 million, or 17.6%, to $32.8 million in the 2025 third quarter compared to net revenue of $27.9 million in the 2024 second quarter (up $4.3 million, or 15.4% on a constant currency basis).

Non-GAAP Financial Measures

To supplement the financial results presented in accordance with generally accepted accounting principles in the United States (“GAAP”), Heidrick & Struggles presents certain non-GAAP financial measures. A “non-GAAP financial measure” is defined as a numerical measure of a company’s financial performance that excludes or includes amounts different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of comprehensive income, balance sheets or statements of cash flow of the Company.

Non-GAAP financial measures used within this earnings release are adjusted EBITDA, adjusted EBITDA margin, and net revenue excluding the impact of exchange rate fluctuations (referred to as constant currency). These measures are presented because management uses this information to monitor and evaluate financial results and allocate resources. Management believes this information is also useful for investors to evaluate the comparability of financial information presented. Reconciliations of these non-GAAP financial measures to the most directly comparable measures calculated and presented in accordance with GAAP are provided as schedules attached to this release.

Adjusted EBITDA refers to net income before interest, taxes, depreciation and amortization, as adjusted, to the extent they occur, for earnout accretion, earnout fair value adjustments, contingent compensation, deferred compensation plan income or expense, certain reorganization costs, transaction fees, impairment charges and restructuring charges.

Adjusted EBITDA margin refers to adjusted EBITDA as a percentage of net revenue in the same period.

The Company evaluates its results of operations on both an as reported and a constant currency basis. The constant currency presentation is a non-GAAP financial measure, which excludes the impact of fluctuations in foreign currency exchange rates. The Company believes providing constant currency information provides valuable supplemental information regarding its results of operations, consistent with how it evaluates its performance. The Company calculates constant currency percentages by converting its financial results in a local currency for a period using the average exchange rate for the prior period to which it is comparing. This calculation may differ from similarly titled measures used by other companies.


Safe Harbor Statement

This press release contains forward-looking statements within the meaning of the federal securities laws, including statements regarding guidance for the third quarter of 2025. The forward-looking statements are based on current expectations, estimates, forecasts, and projections about the industry in which we operate and management's beliefs and assumptions. Forward-looking statements may be identified by the use of words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “outlook,” “projects,” “forecasts,” “aim” and similar expressions. Forward-looking statements are not guarantees of future performance, rely on a number of assumptions, and involve certain known and unknown risks and uncertainties that are difficult to predict, many of which are beyond our control. Factors that may cause actual outcomes and results to differ materially from what is expressed, forecasted or implied in the forward-looking statements include, among other things, our ability to attract, integrate, develop, manage, retain and motivate qualified consultants and senior leaders; our ability to prevent our consultants from taking our clients with them to another firm; our ability to maintain our professional reputation and brand name; our clients’ ability to restrict us from recruiting their employees; our heavy reliance on information management systems; risks arising from our implementation of new technology and intellectual property to deliver new products and services to our clients; our dependence on third parties for the execution of certain critical functions; the fact that we face the risk of liability in the services we perform; the fact that data security, data privacy and data protection laws and other evolving regulations and cross-border data transfer restrictions may limit the use of our services and adversely affect our business; any challenges to the classification of our on-demand talent as independent contractors; the fact that increased cybersecurity requirements, vulnerabilities, threats and more sophisticated and targeted cyber-related attacks could pose a risk to our systems, networks, solutions, services and data; the fact that our net revenue may be affected by adverse macroeconomic or labor market conditions, including impacts of inflation and effects of geopolitical instability; the aggressive competition we face; the impact of foreign currency exchange rate fluctuations; our ability to access additional credit; social, political, regulatory, legal and economic risks in markets where we operate, including the impact of the ongoing war in Ukraine, the conflict between Israel and Hamas and any broader regional conflict in the Middle East, the risks of an expansion or escalation of those conflicts and our ability to quickly and completely recover from any disruption to our business; the impact from actions by the U.S. presidential administration and Congress; unfavorable tax law changes and tax authority rulings; our ability to realize the benefit of our net deferred tax assets; the fact that we may not be able to align our cost structure with net revenue; any impairment of our goodwill, other intangible assets and other long-lived assets; our ability to maintain an effective system of disclosure controls and internal control over our financial reporting and produce accurate and timely financial statements; our ability to execute and integrate future acquisitions; the fact that we have anti-takeover provisions that make an acquisition of us difficult and expensive; risks and uncertainties relating to the transactions contemplated by the Merger Agreement (as defined below), including the occurrence of any event, change, or other circumstance that could give rise to the right of one or both of the parties to terminate the Merger Agreement; the possibility that the Merger and the related transactions do not close when expected or at all because required regulatory, stockholder, or other approvals and other conditions to closing are not waived, received or satisfied on a timely basis or at all; the risk that the benefits from the Merger may not be fully realized; and the diversion of management’s attention and time to the Merger from ongoing business operations and opportunities. We caution the reader that the list of factors may not be exhaustive. For more information on the factors that could affect the outcome of forward-looking statements, refer to our Annual Report on Form 10-K for the year ended December 31, 2024, under the heading "Risk Factors" in Item 1A, and any subsequent Company filings with the Securities and Exchange Commission ("SEC").
