NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(All tables in thousands, except per share figures and percentages)

(Unaudited)

1. Basis of Presentation of Interim Financial Information

The accompanying unaudited Condensed Consolidated Financial Statements of Heidrick & Struggles International, Inc. and subsidiaries (the "Company") have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Significant items subject to estimates and assumptions include revenue recognition, income taxes, interim effective tax rate and the assessment of goodwill, other intangible assets and long-lived assets for impairment. Estimates are subject to a degree of uncertainty and actual results could differ from these estimates. In the opinion of management, all adjustments necessary to fairly present the financial position of the Company at June 30, 2024 and December 31, 2023, the results of operations for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023 have been included and are of a normal, recurring nature except as otherwise disclosed. These financial statements and notes are to be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 4, 2024.

2. Summary of Significant Accounting Policies

A complete listing of the Company’s significant accounting policies is discussed in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Revenue Recognition

See Note 3, Revenue.

Cost of Services

Cost of services consists of third-party contractor costs related to the delivery of various services in the Company's On-Demand Talent and Heidrick Consulting operating segments.

Research and Development

Research and development expense consists of payroll, employee benefits, stock-based compensation, other employee expenses and third-party professional fees associated with new product development.

Marketable Securities

The Company’s marketable securities consist of available-for-sale debt securities with original maturities exceeding three months.

Restricted Cash

The following table provides a reconciliation of the cash and cash equivalents between the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Cash Flows as of June 30, 2024, and 2023, and December 31, 2023, and 2022:


	June 30,				December 31,
	2024		2023		2023		2022
Cash and cash equivalents	$	189,922	$	217,776	$	412,618	$	355,447

Restricted cash included within other non-current assets	—		41		—		42
Total cash, cash equivalents and restricted cash	$	189,922	$	217,817	$	412,618	$	355,489

Earnings (Loss) per Common Share

Basic earnings (loss) per common share are computed by dividing net income (loss) by weighted average common shares outstanding for the period. Diluted earnings (loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings (loss) per share in periods in which they have an anti-dilutive effect.

The following table sets forth the computation of basic and diluted earnings (loss) per share:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Net income (loss)	$	(5,157)	$	8,982	$	8,875	$	24,568
Weighted average shares outstanding:
Basic	20,259		20,010		20,202		19,958
Effect of dilutive securities:
Restricted stock units	—		516		615		584
Performance stock units	—		111		244		159
Diluted	20,259		20,637		21,061		20,701
Basic earnings (loss) per share	$	(0.25)	$	0.45	$	0.44	$	1.23
Diluted earnings (loss) per share	$	(0.25)	$	0.44	$	0.42	$	1.19

Weighted average restricted stock units and performance stock units outstanding that could be converted into approximately 474,000 and 132,000 common shares, respectively, for the three months ended June 30, 2024, were not included in the computation of diluted earnings (loss) per share because the effects would be anti-dilutive.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets, Current liabilities - Operating lease liabilities and Non-current liabilities - Operating lease liabilities in the Company's Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components. For office leases, the Company accounts for the lease and non-lease components as a single lease component. For equipment leases, such as vehicles and office equipment, the Company accounts for the lease and non-lease components separately.

Goodwill

The goodwill impairment test compares the fair value of a reporting unit to its carrying amount, including goodwill. The Company operates five reporting units: Americas, Europe (which includes Africa), Asia Pacific (which includes the Middle East), On-Demand Talent and Heidrick Consulting. The fair value of each of the Company’s reporting units is determined using a discounted cash flow methodology. An impairment charge is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit.

As a result of triggering events, the Company performed interim goodwill impairment evaluations during the three months ended June 30, 2024, and 2023, when the Company determined that it was more likely than not that the fair value of at least one of its reporting units was less than its respective carrying amount.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions to evaluate the impact of operating and macroeconomic changes on each reporting unit. During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. The discounted cash flow approach is dependent on a number of factors, including estimates of future market growth and trends, forecasted revenue and costs, capital investments, appropriate discount rates, certain assumptions to allocate shared costs, assets and liabilities, historical and projected performance of the reporting unit, and the macroeconomic conditions affecting each of the Company’s reporting units. The assumptions used in the determination of fair value were (1) a forecast of growth in the near and long term; (2) the discount rate; (3) working capital investments; (4) macroeconomic conditions; and (5) other factors. As part of the goodwill impairment evaluation, the Company performed a reconciliation of its market capitalization to the aggregated estimated fair value of all reporting units, including consideration of a control premium.

Based on the results of the 2024 impairment evaluation, the Company determined that the goodwill within the On-Demand Talent and Europe reporting units were impaired, which resulted in impairment charges of $14.8 million and $1.5 million, respectively. Based on the results of the 2023 impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million. The impairment charges are recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income (Loss) for the three and six months ended June 30, 2024, and 2023 and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2024, and 2023. The impairments were non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations; nor did they impact the debt covenants under the Company's credit agreement.

Recently Issued Financial Accounting Standards

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." The standard is intended to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its financial statements.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The standard is intended to improve reportable segment disclosure requirements for public business entities primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit (referred to as the “significant expense principle”). This guidance is effective for annual periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The Company is currently evaluating the impact of this guidance on its financial statements.

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance was intended to provide temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. This guidance is effective March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2024. The new guidance is not expected to have a material effect on the Company's financial statements.

3. Revenue

Executive Search

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Generally, each executive search contract contains one performance obligation which is the process of identifying potentially qualified candidates for a specific client position. In most contracts, the transaction price includes both fixed and variable consideration. Fixed compensation is comprised of a retainer, equal to approximately one-third of the estimated first year compensation for the position to be filled, and indirect expenses, equal to a specified percentage of the retainer, as defined in the contract. The Company generally bills clients for the retainer and indirect expenses in one-third increments over a three-month period commencing in the month of a client’s acceptance of the contract. If actual compensation of a placed candidate exceeds the original compensation estimate, the Company is often authorized to bill the client for one-third of the excess compensation. The Company refers to this additional billing as uptick revenue. In most contracts, variable consideration is comprised of uptick revenue and direct expenses. The Company bills its clients for uptick revenue upon completion of the executive search, and direct expenses are billed as incurred.

The Company estimates uptick revenue at contract inception, based on a portfolio approach, utilizing the expected value method based on a historical analysis of uptick revenue realized in the Company’s geographic regions and industry practices, and initially records a contract’s uptick revenue in an amount that is probable not to result in a significant reversal of cumulative revenue recognized when the actual amount of uptick revenue for the contract is known. Differences between the estimated and actual amounts of variable consideration are recorded when known. The Company does not estimate revenue for direct expenses as it is not materially different than recognizing revenue as direct expenses are incurred.

Revenue from executive search engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. Revenue from executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill the obligations under the executive search contract. Revenue is generally recognized over a period of approximately six months.

The Company's executive search contracts contain a replacement guarantee which provides for an additional search to be completed, free of charge except for expense reimbursements, should the candidate presented by the Company be hired by the client and subsequently terminated by the client for performance reasons within a specified period of time. The replacement guarantee is an assurance warranty, which is not a performance obligation under the terms of the executive search contract, as the Company does not provide any services under the terms of the guarantee that transfer benefits to the client in excess of assuring that the identified candidate complies with the agreed-upon specifications. The Company accounts for the replacement guarantee under the relevant warranty guidance in Accounting Standards Codification 460 - Guarantees.

On-Demand Talent

The Company enters into contracts with clients that outline the general terms and conditions of the assignment to provide on-demand consultants for various types of consulting projects, which consultants may be independent contractors or temporary employees. The consideration the Company expects to receive under each contract is dependent on the time-based fees specified in the contract. Revenue from on-demand engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. The Company has applied the practical expedient to recognize revenue for these services in the amount to which the Company has a right to invoice the client, as this amount corresponds directly with the value provided to the client for the performance completed to date. For transactions where a third-party contractor is involved in providing the services to the client, the Company reports the revenue and the related direct costs on a gross basis as it has determined that it is the principal in the transaction. The Company is primarily responsible for fulfilling the promise to provide consulting services to its clients and the Company has discretion in establishing

the prices charged to clients for the consulting services and is able to contractually obligate the independent service provider to deliver services and deliverables that the Company has agreed to provide to its clients.

Heidrick Consulting

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Heidrick Consulting enters into contracts with clients that outline the general terms and conditions of the assignment to provide succession planning, executive assessment, top team and board effectiveness and culture shaping programs. The consideration the Company expects to receive under each contract is generally fixed. Most of the Company's consulting contracts contain one performance obligation, which is the overall process of providing the consulting service requested by the client. The majority of the Company's consulting revenue is recognized over time utilizing input methods. Revenue recognition over time for the majority of the Company's consulting engagements is measured by total cost or time incurred as a percentage of the total estimated cost or time on the consulting engagement.

Contract Balances

Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities are classified as current due to the nature of the Company's contracts, which are completed within one year. Contract assets are included within Other current assets on the Condensed Consolidated Balance Sheets.

Unbilled receivables: Unbilled receivables represents contract assets from revenue recognized over time in excess of the amount billed to the client and the amount billed to the client is solely dependent upon the passage of time. This amount includes revenue recognized in excess of billed Executive Search retainers, Heidrick Consulting fees, and On-Demand Talent fees.

Contract assets: Contract assets represent revenue recognized over time in excess of the amount billed to the client, and the amount billed to the client is not solely subject to the passage of time. This amount primarily includes revenue recognized for upticks and contingent placement fees in executive search contracts.

Deferred revenue: Contract liabilities consist of deferred revenue, which is equal to billings in excess of revenue recognized.

The following table outlines the changes in the contract asset and liability balances from December 31, 2023, to June 30, 2024:


	June 30, 2024		December 31, 2023		Change
Contract assets
Unbilled receivables, net	$	19,878	$	15,318	$	4,560
Contract assets	16,112		16,774		(662)
Total contract assets	35,990		32,092		3,898

Contract liabilities
Deferred revenue	$	44,679	$	45,732	$	(1,053)

During the six months ended June 30, 2024, the Company recognized revenue of $36.2 million that was included in the contract liabilities balance at the beginning of the period. The amount of revenue recognized during the six months ended June 30, 2024, from performance obligations partially satisfied in previous periods as a result of changes in the estimates of variable consideration was $19.1 million.

Each of the Company's contracts has an expected duration of one year or less. Accordingly, the Company has elected to utilize the available practical expedient related to the disclosure of the transaction price allocated to the remaining performance obligations under its contracts. The Company has also elected the available practical expedients related to adjusting for the effects of a significant financing component and the capitalization of contract acquisition costs. The Company charges and collects from its clients sales tax and value added taxes as required by certain jurisdictions. The Company has made an accounting policy election to exclude these items from the transaction price in its contracts.

4. Credit Losses

The Company is exposed to credit losses primarily through the provision of its executive search, consulting, and on-demand talent services. The Company’s expected credit loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of clients' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of the amount of accounts receivable that may not be collected is primarily based on historical loss-rate experience. When required, the Company adjusts the loss-rate methodology to account for current conditions and reasonable and supportable expectations of future economic and market conditions. The Company generally assesses future economic conditions for a period of sixty to ninety days, which corresponds with the contractual life of its accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for clients that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of clients' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

The activity in the allowance for credit losses on the Company's trade receivables is as follows:


Balance at December 31, 2023	$	6,954
Provision for credit losses	3,674
Write-offs	(3,051)
Foreign currency translation	366
Balance at June 30, 2024	$	7,943

There were no investments with unrealized losses at June 30, 2024, and December 31, 2023.

5. Property and Equipment, net

The components of the Company’s property and equipment are as follows:


	June 30, 2024		December 31, 2023
Leasehold improvements	$	49,895	$	45,050
Office furniture, fixtures and equipment	15,132		14,775
Computer equipment and software	43,024		38,798
Property and equipment, gross	108,051		98,623
Accumulated depreciation	(59,617)		(62,871)
Property and equipment, net	$	48,434	$	35,752

Depreciation expense for the three months ended June 30, 2024, and 2023, was $2.0 million and $2.2 million, respectively. Depreciation expense for the six months ending June 30, 2024, and 2023, was $4.5 million and $4.2 million, respectively.

6. Leases

The Company's lease portfolio is comprised of operating leases for office space and equipment. The majority of the Company's leases include both lease and non-lease components, which the Company accounts for differently depending on the underlying class of asset. Certain of the Company's leases include one or more options to renew or terminate the lease at the Company's discretion. Generally, the renewal and termination options are not included in the right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal and termination options and, when they are reasonably certain of exercise, includes the renewal or termination option in the lease term.

As most of the Company's leases do not provide an implicit interest rate, the Company utilizes an incremental borrowing rate based on the information available at the commencement date of the lease in determining the present value of lease payments. The Company has a centrally managed treasury function and, therefore, a portfolio approach is applied in determining the incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a fully collateralized basis over a similar term in an amount equal to the total lease payments in a similar economic environment.

As of June 30, 2024, office leases have remaining lease terms that range from less than one year to 11.7 years, some of which also include options to extend or terminate the lease. Most office leases contain both fixed and variable lease payments. Variable lease costs consist primarily of rent escalations based on an established index or rate and taxes, insurance, and

common area or other maintenance costs, which are paid based on actual costs incurred by the lessor. The Company has elected to utilize the available practical expedient to not separate lease and non-lease components for office leases.

As of June 30, 2024, equipment leases, which are comprised of vehicle and office equipment leases, have remaining terms that range from less than one year to 4.7 years, some of which also include options to extend or terminate the lease. The Company's equipment leases do not contain variable lease payments. The Company separates the lease and non-lease components for its equipment leases. Equipment leases do not comprise a significant portion of the Company's lease portfolio.

Lease cost components included within Operating expenses - General and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income were as follows:

Investments, Assets Designated for Retirement and Pension Plans and Associated Liabilities

The Company has a U.S. non-qualified deferred compensation plan that consists primarily of U.S. marketable securities and mutual funds. The aggregate cost basis for these investments was $42.8 million and $37.2 million as of June 30, 2024, and December 31, 2023, respectively.

The Company also maintains a pension plan for certain current and former employees in Germany. The pensions are individually fixed Euro amounts that vary depending on the function and the eligible years of service of the employee. The Company’s investment strategy is to support its pension obligations through reinsurance contracts. The BaFin—German Federal Financial Supervisory Authority—supervises the insurance companies and the reinsurance contracts. The BaFin requires each reinsurance contract to guarantee a fixed minimum return. The Company’s pension benefits are fully reinsured by group insurance contracts with ERGO Lebensversicherung AG, and the group insurance contracts are measured in accordance with BaFin guidelines (including mortality tables and discount rates) which are considered Level 2 inputs.

The following tables provide a summary of the fair value measurements for each major category of investments, assets designated for retirement and pension plans and associated liabilities measured at fair value:

Contingent Consideration and Compensation

The former owners of certain of the Company's acquired businesses are eligible to receive additional cash consideration based on the attainment of certain operating metrics in the periods subsequent to acquisition. Contingent consideration and compensation are valued using significant inputs that are not observable in the market, which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of contingent consideration and compensation using a variation of the income approach, known as the real options method. The significant unobservable inputs utilized in the real options method include (1) revenue forecasts; (2) operating expense forecasts; (3) the discount rate; and (4) volatility.

The following table provides a reconciliation of the beginning and ending balance of Level 3 liabilities for the six months ended June 30, 2024:


	Earnout		Contingent Compensation
Balance at December 31, 2023	$	(38,601)	$	(18,878)

Earnout accruals of $39.7 million and $38.6 million were recorded within Non-current liabilities - Other non-current liabilities as of June 30, 2024, and December 31, 2023, respectively. Contingent compensation accruals of $4.0 million and $6.0 million are recorded within Current liabilities - Accrued salaries and benefits as of June 30, 2024, and December 31, 2023, respectively, and contingent compensation accruals of $14.4 million and $12.9 million are recorded within Non-current liabilities - Accrued salaries and benefits as of June 30, 2024, and December 31, 2023, respectively.

Goodwill

Goodwill represents the difference between the purchase price of acquired businesses and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. During the three months ended June 30, 2024, an interim goodwill impairment evaluation was conducted to determine the fair value of the Company's reporting units. As a result of this evaluation, the Company recorded impairment charges in the On-Demand Talent and Europe reporting units of $14.8 million and $1.5 million, respectively. The fair value of the reporting units is valued using significant inputs that are not observable in the market which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of its reporting units using discounted cash flow models.

Other Investments

The Company holds an equity investment that does not have a readily determinable fair value for which the Company uses the measurement alternative prescribed in FASB Accounting Standards Codification Topic 321, Investments-Equity Securities. As of June 30, 2024, the Company held equity investments under the measurement alternative of $11.0 million which are presented in Other non-current assets in the Condensed Consolidated Balance Sheets. There were no impairments or changes resulting from observable transactions for these investments in the three and six months ended June 30, 2024 and no adjustments have been made to the carrying values as of June 30, 2024. There were no equity investments as of December 31, 2023.

8. Acquisitions

On February 1, 2023, the Company acquired Atreus Group GmbH ("Atreus"), a leading provider of executive interim management in Germany. The Company paid $33.4 million in the first quarter of 2023, with a subsequent purchase price adjustment payment of $12.1 million in the fourth quarter of 2023. The former owners of Atreus are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $30.0 million and $40.0 million, to be paid in 2026 based on the achievement of certain revenue and operating income milestones for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $32.0 million as of the acquisition date for the earnout liability. The Company recorded $11.3 million for customer relationships, $5.4 million for software, $2.5 million for a trade name and $62.4 million of goodwill. Goodwill is primarily related to the acquired workforce and strategic fit and is not deductible for tax purposes.

On April 1, 2023, the Company acquired businessfourzero, a next generation consultancy specializing in developing and implementing purpose-driven change. In connection with the acquisition, the Company paid $9.5 million in the second quarter of 2023 with a subsequent purchase price adjustment payment of $2.2 million paid in the third quarter of 2023. The former owners of businessfourzero are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $4.0 million and $8.0 million, to be paid in 2026 based on the achievement of certain revenue and operating income metrics for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $4.3 million as of the acquisition date for the earnout liability.

11. Line of Credit

On February 24, 2023, the Company entered into the Second Amendment (the “Second Amendment”) to the Credit Agreement, dated as of October 26, 2018 (the “Credit Agreement” and, as amended by the First Amendment to Credit Agreement, dated as of July 13, 2021, and the Second Amendment, the "Amended Credit Agreement") by and among the Company, Bank of America, N.A., as administrative agent, and the lenders party thereto. The Second Amendment changed the interest rate benchmark, from LIBOR to the Secured Overnight Financing Rate (“SOFR”). At the Company's option, borrowings under the Amended Credit Agreement will bear interest at one-, three- or six-month term SOFR, or an alternate base rate as set forth in the Amended Credit Agreement, in each case plus an applicable margin. Additionally, the Amended Credit Agreement provides the Company with a committed unsecured revolving credit facility in an aggregate amount of $200 million, increased in the Second Amendment from $175 million as set forth in the original version of the Credit Agreement, which includes a sublimit of $25 million for letters of credit and a sublimit of $10 million for swingline loans, with a $75 million expansion feature. The Amended Credit Agreement matures on July 13, 2026.

Borrowings under the Amended Credit Agreement may be used for working capital, capital expenditures, permitted acquisitions, restricted payments and for other general corporate purposes of the Company and its subsidiaries. The obligations under the Amended Credit Agreement are guaranteed by certain of the Company’s subsidiaries.

As of June 30, 2024, and December 31, 2023, the Company had no outstanding borrowings. As of such dates, the Company was in compliance with the financial and other covenants under the Amended Credit Agreement and no event of default existed.

12. Stock-Based Compensation and Common Stock

On May 23, 2024, the stockholders of the Company approved an amendment and restatement of the Company's Fourth Amended and Restated 2012 Heidrick & Struggles GlobalShare Program (as so amended, the "Fifth A&R Program") to increase the number of shares of common stock reserved for issuance under the plan by 649,000 shares, among other things. The Fifth A&R Program provides for grants of stock options, stock appreciation rights, restricted stock units, performance stock units, and other stock-based compensation awards that are valued based upon the grant date fair value of the awards. These awards may be granted to directors, selected employees and independent contractors.

As of June 30, 2024, 4,744,660 awards have been issued under the Fifth A&R Program, including 792,136 forfeited awards, and 834,082 shares remain available for future awards assuming performance stock units vest at maximum levels. The Fifth A&R Program provides that no awards can be granted after the first annual meeting of the Company's stockholders to occur on or after May 23, 2034.

The Company measures its stock-based compensation costs based on the grant date fair value of the awards and recognizes these costs over the requisite service period.

A summary of information with respect to stock-based compensation is as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Salaries and benefits (1)	$	2,429	$	806	$	5,870	$	3,403
General and administrative expenses	1,050		810		1,050		810
Income tax benefit related to stock-based compensation included in net income	958		445		1,907		1,160

(1) Includes $0.1 million of expense and $0.7 million of income related to cash-settled restricted stock units for the three months ended June 30, 2024, and 2023, respectively, and $0.9 million and $0.1 million of expense related to cash-settled restricted stock units for the six months ended June 30, 2024, and 2023, respectively.

Restricted Stock Units

Restricted stock units granted to employees are subject to ratable vesting over a three-year or four-year period dependent upon the terms of the individual grant. Compensation expense related to service-based restricted stock units is recognized on a straight-line basis over the vesting period.

Non-employee members of the Board of Directors may elect to receive restricted stock units or shares of common stock annually pursuant to the Fifth A&R Program as part of their annual compensation. Based on their respective elections, the Company issued 16,752 and 16,134 restricted stock units for services provided by the non-employee directors during the three months ended June 30, 2024, and 2023, respectively. Restricted stock units issued to non-employee directors remain unvested until the respective non-employee directors retire from the Board of Directors.

Restricted stock unit activity for the six months ended June 30, 2024, is as follows:


	Number of Restricted Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2023	686,741	$	30.33
Granted	292,447	33.42
Vested and converted to common stock	(193,056)	33.08
Forfeited	(7,091)	30.15
Outstanding on June 30, 2024	779,041	$	30.81

As of June 30, 2024, there was $10.6 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.4 years.

Performance Stock Units

The Company grants performance stock units to certain of its senior executives. The majority of performance stock units are subject to cliff vesting at the end of a three-year period. The vesting will vary between 0% and 200% based on the attainment of certain performance and market conditions over the three-year vesting period. Half of the award is based on the achievement of adjusted operating margin or Adjusted EBITDA margin thresholds and half of the award is based on the Company's total shareholder return, relative to a peer group. The fair value of the awards subject to total shareholder return metrics is determined using the Monte Carlo simulation model. A Monte Carlo simulation model uses stock price volatility and other variables to estimate the probability of satisfying the performance conditions and the resulting fair value of the award. The performance stock units are expensed on a straight-line basis over the three-year vesting period.

Certain of the Company's senior executives are granted performance stock units that are subject to ratable vesting over a four-year period. The vesting will vary between 0% and 100% of the shares subject to the performance stock units based on the attainment of specified stock price hurdles over the vesting period. The fair value of the awards subject to such stock price hurdles is determined using the Monte Carlo simulation model. The performance stock units are expensed on a straight-line basis over the derived service period, which ranges from one to four-years.

Performance stock unit activity for the six months ended June 30, 2024, is as follows:


	Number of Performance Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2023	239,625	$	41.91
Granted	273,536	32.64
Vested and converted to common stock	(104,154)	44.18
Forfeited	(720)	27.82
Outstanding on June 30, 2024	408,287	$	35.14

As of June 30, 2024, there was $8.3 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.6 years.

Phantom Stock Units

Phantom stock units are grants of phantom stock with respect to shares of the Company's common stock that are settled in cash and are subject to various restrictions, including restrictions on transferability, vesting and forfeiture provisions. Shares of phantom stock that do not vest for any reason will be forfeited by the recipient and will revert to the Company.

Phantom stock units are subject to vesting over a three-year or four-year period, and such vesting is subject to certain other conditions, including continued service to the Company. As a result of the cash-settlement feature of the awards, the Company classifies the awards as liability awards, which are measured at fair value at each reporting date and the vested portion of the award is recognized as a liability to the extent that the service condition is deemed probable. The fair value of the phantom stock awards on the balance sheet date is determined using the closing share price of the Company's common stock on that date.

The Company recorded phantom stock-based compensation expense of less than $0.1 million of expense and $0.7 million of income related to cash-settled restricted stock units for the three months ended June 30, 2024, and 2023, respectively, and $0.9 million and $0.1 million of expense related to cash-settled restricted stock units for the six months ended June 30, 2024, and 2023, respectively.

Phantom stock unit activity for the six months ended June 30, 2024, is as follows:


			Number of Phantom Stock Units
Outstanding on December 31, 2023			187,301
Granted			33,247
Vested			—
Forfeited			—
Outstanding on June 30, 2024			220,548

As of June 30, 2024, there was $1.6 million of pre-tax unrecognized compensation expense related to unvested phantom stock units, which is expected to be recognized over a weighted average of 2.5 years.

Common Stock

Non-employee members of the Board of Directors may elect to receive restricted stock units or shares of common stock annually pursuant to the Fifth A&R Program as part of their annual compensation, which is typically issued in the second quarter each year. The Company issued 12,564 and 16,134 shares of common stock for services provided by the non-employee directors during the three months ended June 30, 2024, and 2023, respectively.

On February 11, 2008, the Company's Board of Directors authorized management to repurchase shares of the Company's common stock with an aggregate purchase price of up to $50 million (the "Repurchase Authorization"). From time to time and as business conditions warrant, the Company may purchase shares of its common stock on the open market or in negotiated or block trades. No time limit has been set for completion of this program. There were no repurchases of common stock during the three or six months ended June 30, 2024. During the three and six months ended June 30, 2023, the Company purchased 36,000 shares of common stock for $0.9 million. Prior to 2023, the most recent purchase of the Company's shares of common stock occurred during the year ended December 31, 2012. As of June 30, 2024, the Company has purchased 1,074,670 shares of its common stock pursuant to the Repurchase Authorization for a total of $29.2 million and $20.8 million remains available for future purchases under the Repurchase Authorization.

16. Segment Information

The Company has five operating segments. The Executive Search business operates in the Americas, Europe (which includes Africa) and Asia Pacific (which includes the Middle East), and the Heidrick Consulting and On-Demand Talent businesses operate globally.

In 2023, the Company changed its measure of segment profitability from operating income to Adjusted EBITDA. The following tables include Adjusted EBITDA, which is the measure of segment profitability reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance. For segment purposes, reimbursements of out-of-pocket expenses classified as revenue and other operating income are reported separately and, therefore, are not included in the results of each segment. The Company believes that analyzing trends in revenue before reimbursements (net revenue), analyzing operating expenses as a percentage of net revenue, and analyzing Adjusted EBITDA and Adjusted EBITDA margin more appropriately reflect its core operations.

The Company evaluates performance and allocates resources based on the chief operating decision maker’s review of (1) net revenue and (2) Adjusted EBITDA, which is defined as net income before interest, other income or expense, income 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, impairment charges and restructuring charges. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of revenue in the same period.

17. Guarantees

The Company has utilized letters of credit to support certain obligations, primarily for its office lease agreements. The letters of credit were made to secure the respective agreements and are for the terms of the agreements, which extend through 2033. For each letter of credit issued, the Company would have to use cash to fulfill the obligation if there is a default on a payment. The maximum amount of undiscounted payments the Company would be required to make in the event of default on all outstanding letters of credit is approximately $4.8 million as of June 30, 2024. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

18. Commitments and Contingencies

Litigation

The Company has contingent liabilities from various pending claims and litigation matters arising in the ordinary course of the Company’s business, some of which involve claims for damages that are substantial in amount. Some of these matters are covered in part by insurance. Based upon information currently available, the Company believes the ultimate resolution of such claims and litigation will not have a material adverse effect on its financial condition, results of operations or liquidity.

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements. Forward-looking statements are not historical facts or guarantees of future performance, but instead represent only our beliefs, assumptions, expectations, estimates, forecasts and projections regarding future events, many of which, by their nature, are inherently uncertain and outside our control. 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. These statements include statements other than historical information or statements of current condition and may relate to our future plans and objectives and results. By identifying these statements for you in this manner, we are alerting you to the possibility that our actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements.

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 and the conflict in Israel and the Gaza strip, the risks of an expansion or escalation of those conflicts and our ability to quickly and completely recover from any disruption to our business; 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; and the fact that we have anti-takeover provisions that make an acquisition of us difficult and expensive.

Executive Overview

Our Business. Heidrick & Struggles International, Inc. (the "Company," "we," "us," or "our") is a human capital leadership advisory firm providing executive search, consulting and on-demand talent services to businesses and business leaders worldwide to help them to improve the effectiveness of their leadership teams. We provide our services to a broad range of clients through the expertise of 500 consultants located in major cities around the world. The Company and its predecessors have been leadership advisors for more than 70 years.

Our service offerings include the following:

Executive Search. We partner with our clients, respected organizations across the globe, to help them build and sustain the best leadership teams in the world, with a specialized focus on the placement of top-level senior executives. Through our unique relationship-based, data-driven approach, we help our clients find the right leaders, set them up for success, and accelerate their and their team’s performance.

We believe focusing on top-level senior executives provides the opportunity for several competitive advantages including access to and influence with key decision makers, increased potential for recurring search and consulting engagements, higher

fees per search engagement, enhanced brand visibility, and a leveraged global footprint. Working at the top of client organizations also facilitates the attraction and retention of high-caliber consultants who desire to serve top industry executives and their leadership needs. Our executive search services derive revenue through the fees generated for each search engagement, which generally are based on the annual compensation for the placed executive. We provide our executive search services primarily on a retained basis.

We employ a global approach to executive search built on better insights, more data and faster decision making facilitated by the use of our Heidrick Leadership Framework and Heidrick Connect. Our Heidrick Leadership Framework allows clients to holistically evaluate a candidate's pivotal experience and expertise, leadership capabilities, agility and potential, and culture fit and impact, thereby allowing our clients to find the right person for the role. We supplement our Heidrick Leadership Framework through a series of additional online tools including our Leadership Accelerator, Leadership Signature and Culture Signature assessments. Heidrick Connect, a completely digital, always available client experience portal, allows our clients to access talent insights for each engagement, including the Heidrick Leadership Framework and other internally developed assessment tools. In response to working remotely, our Executive Search teams employed Heidrick Connect to operate effectively and efficiently while engaging virtually with our clients. Additionally, we have introduced upgrades to Heidrick Connect, resulting in greater flexibility, increased productivity and the ability to deliver more insights to our clients.

The executive search industry consists of several thousand executive search firms worldwide. Executive search firms are generally separated into two broad categories: retained search and contingency search. Retained executive search firms fulfill their clients’ senior leadership needs by identifying potentially qualified candidates and assisting clients in evaluating and assessing these candidates. Retained executive search firms generally are compensated for their services regardless of whether the client employs a candidate identified by the search firm and are generally retained on an exclusive basis. Typically, retained executive search firms are paid a retainer for their services equal to approximately one-third of the estimated first year compensation for the position to be filled. In addition, if the actual compensation of a placed candidate exceeds the estimated compensation, executive search firms often are authorized to bill the client for one-third of the excess. In contrast, contingency search firms are compensated only upon successfully placing a recommended candidate.

We are a retained executive search firm. Our search process typically consists of the following steps:

Key Performance Indicators

We manage and assess our performance through various means, with primary financial and operational measures including net revenue, Adjusted EBITDA (defined below; non-GAAP) and Adjusted EBITDA margin (defined below; non-GAAP). These non-GAAP financial measures should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP (defined below). Executive Search and Heidrick Consulting performance is also measured using consultant headcount. Specific to Executive Search, confirmed search (confirmation) trends, consultant productivity and average revenue per search are used to measure performance. Productivity is as measured by annualized Executive Search net revenue per consultant.

Revenue is driven by market conditions and a combination of the number of executive search engagements, consulting projects, on-demand projects and the average revenue per search or project. With the exception of compensation expense and cost of sales, incremental increases in revenue do not necessarily result in proportionate increases in costs, particularly operating and administrative expenses, thus creating the potential to improve Adjusted EBITDA and Adjusted EBITDA margin.

The number of consultants, confirmation trends, number of searches or projects completed, productivity levels and the average revenue per search or project will vary from quarter to quarter, affecting net revenue, Adjusted EBITDA and Adjusted EBITDA margin.

Consolidated Adjusted EBITDA and Adjusted EBITDA margin and total Executive Search Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP financial measures and have limitations as analytical tools. They should not be viewed as a substitute for financial information determined in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP. In addition, they may not necessarily be comparable to non-GAAP performance measures that may be presented by other companies.

We believe the presentation of these non-GAAP financial measures provides meaningful supplemental information and, when presented together with financial measures that have been determined in accordance with GAAP, a more complete understanding of our ongoing operating results, including underlying trends. These non-GAAP financial measures are used by management in their financial and operating decision making because management believes they reflect our ongoing business in a manner that allows for meaningful period-to-period comparison and evaluation. We also believe that these non-GAAP financial measures, when considered together with our GAAP financial measures, provide management and investors with additional information for comparison of our operating results with the operating results of other companies.

Our Compensation Model

At the consultant level, there are fixed and variable components of compensation. Individuals are rewarded for their performance based on a system that directly ties a portion of their compensation to the amount of net revenue for which they are responsible. A portion of the reward may be based upon individual performance against a series of non-financial measures. Credit towards the variable portion of a consultant’s compensation is earned by generating net revenue for winning and executing work. Each quarter, we review and update the expected annual performance of all consultants and accrue variable compensation accordingly. The amount of variable compensation that is accrued for each consultant is based on a tiered payout model. Overall, Company performance determines the amount available for total variable compensation. The more net revenue that is generated by the consultant, the higher the percentage credited towards the consultant’s variable compensation and thus accrued by our Company as expense.

The mix of individual consultants who generate revenue can significantly affect the total amount of compensation expense recorded, which directly impacts operating margin. As a result, the variable portion of the compensation expense may fluctuate significantly from quarter to quarter. The total variable compensation is discretionary and is based on Company-wide financial targets approved by the Human Resources and Compensation Committee of the Board of Directors. We pay annual bonuses in the first half of the year following the year in which they are earned.

General. We continually evaluate our liquidity requirements, capital needs and availability of capital resources based on our operating needs. We believe that our available cash balances, funds expected to be generated from operations and funds available under our committed revolving credit facility will be sufficient to finance our operations for at least the next 12 months and the foreseeable future, as well as to finance the cash payments associated with our cash dividends and stock repurchase program.

We pay annual bonuses in the first half of the year following the year in which they are earned. Employee bonuses are accrued throughout the year and are based on our performance and the performance of the individual employee.

Lines of credit. On February 24, 2023, the Company entered into the Second Amendment (the “Second Amendment”) to the Credit Agreement, dated as of October 26, 2018 (the “Credit Agreement” and, as amended by the First Amendment to Credit Agreement, dated as of July 13, 2021, and the Second Amendment, the "Amended Credit Agreement") by and among the Company, Bank of America, N.A., as administrative agent, and the lenders party thereto. The Second Amendment changed the interest rate benchmark, from the London Interbank Offered Rate to the Secured Overnight Financing Rate (“SOFR”). At the Company's option, borrowings under the Amended Credit Agreement will bear interest at one-, three- or six-month term SOFR, or an alternate base rate as set forth in the Amended Credit Agreement, in each case plus an applicable margin. Additionally,

the Amended Credit Agreement provides the Company with a committed unsecured revolving credit facility in an aggregate amount of $200 million, increased in the Second Amendment from $175 million as set forth in the original version of the Credit Agreement, which includes a sublimit of $25 million for letters of credit and a sublimit of $10 million for swingline loans, with a $75 million expansion feature. The Amended Credit Agreement matures on July 13, 2026.

Cash, cash equivalents and marketable securities. Cash, cash equivalents and marketable securities at June 30, 2024, December 31, 2023, and June 30, 2023, were $296.9 million, $478.2 million and $239.0 million, respectively. The $296.9 million of cash, cash equivalents and marketable securities at June 30, 2024, includes $141.2 million held by our foreign subsidiaries. A portion of the $141.2 million is considered permanently reinvested in these foreign subsidiaries. If these funds were required to satisfy obligations in the U.S., the repatriation of these funds could cause us to incur additional U.S. income taxes or foreign withholding taxes.

Cash flows used in operating activities. Cash used in operating activities was $140.9 million for the six months ended June 30, 2024, primarily reflecting a decrease in accrued expenses of $124.7 million and an increase in accounts receivable of $55.8 million, partially offset by net income net of non-cash charges of $37.8 million. The decrease in accrued expenses is primarily due to cash bonus payments related to 2023 of $289.8 million, partially offset by 2024 bonus accruals.

Cash used in operating activities was $290.1 million for the six months ended June 30, 2023, primarily reflecting a decrease in accrued expenses of $273.8 million and an increase in accounts receivable of $60.0 million, partially offset by net income net of non-cash charges of $49.8 million. The decrease in accrued expenses is primarily due to cash bonus payments related to 2022 and prior year cash bonus deferrals of $422.0 million, partially offset by 2023 bonus accruals.

Cash flows provided by (used in) investing activities. Cash used in investing activities was $65.2 million for the six months ended June 30, 2024, primarily due to purchases of marketable securities and investments of $115.3 million, and capital expenditures of $16.5 million, partially offset by proceeds from the sale of marketable securities and investments of $66.6 million.

Cash provided by investing activities was $197.9 million for the six months ended June 30, 2023, due to proceeds from sales of marketable securities and investments of $268.1 million, partially offset by payments for the acquisitions of Atreus and businessfourzero of $35.7 million, purchases of marketable securities and investments of $27.7 million, and capital expenditures of $6.8 million.

Cash flows used in financing activities. Cash used in financing activities was $10.1 million for the six months ended June 30, 2024, consisting of dividend payments of $6.4 million and employee tax withholding payments on equity transactions of $3.7 million.

Cash used in financing activities was $47.2 million for the six months ended June 30, 2023, due to the Business Talent Group earnout payment of $35.9 million, dividend payments of $6.2 million, and employee tax withholding payments on equity transactions of $4.1 million.

Off-Balance Sheet Arrangements. We do not have material off-balance sheet arrangements, special purpose entities, trading activities of non-exchange traded contracts or transactions with related parties.

Contractual obligations. Our lease portfolio is comprised of operating leases for office space and equipment. As of June 30, 2024, we had aggregate future lease payment obligations of $96.2 million, with $18.0 million payable within 12 months. Associated with our lease portfolio, we have asset retirement obligations for the retirement of tangible long-lived assets related to our obligation at the end of the lease term to return office space to the landlord in its original condition. As of June 30, 2024, we had asset retirement obligations of $2.8 million, with $0.7 million payable within 12 months.

In addition to lease-related contractual obligations, we also have liabilities related to certain employee benefit plans. These liabilities are recorded in our Consolidated Balance Sheet at June 30, 2024. The obligations related to these employee benefit

plans are described in Note 12, Employee Benefit Plans, and Note 13, Pension Plan and Life Insurance Contract, in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 4, 2024. As of June 30, 2024, we did not have a liability for uncertain tax positions.

Application of Critical Accounting Policies and Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our Condensed Consolidated Financial Statements, which have been prepared using accounting principles generally accepted in the United States of America. Our significant accounting policies are discussed in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on March 4, 2024, and in Note 2, Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. If actual amounts are ultimately different from previous estimates, the revisions are included in our results of operations for the period in which the actual amounts become known.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or if changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. Management believes its critical accounting policies that reflect its more significant estimates and assumptions relate to revenue recognition, income taxes, interim effective tax rate and assessment of goodwill and other intangible assets for impairment. See Application of Critical Accounting Policies and Estimates in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 4, 2024.

Recently Issued and Adopted Financial Accounting Standards

The information presented in Note 2, Summary of Significant Accounting Policies, to our Condensed Consolidated Financial Statements within this Quarterly Report on Form 10-Q is incorporated herein by reference.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Currency market risk. With our operations in the Americas, Europe, and Asia Pacific, we conduct business using various currencies. Revenue earned in each country is generally matched with the associated expenses incurred, thereby reducing currency risk to earnings. However, because certain assets and liabilities are denominated in currencies other than the U.S. dollar, changes in currency rates may cause fluctuations in the valuation of such assets and liabilities. As the local currency of our subsidiaries has generally been designated as the functional currency, we are affected by the translation of foreign currency financial statements into U.S. dollars. A 10% change in the average exchange rate for currencies of all foreign countries in which we operate would have increased or decreased our net income by approximately $0.3 million for the six months ended June 30, 2024. For financial information by segment, see Note 16, Segment Information, in the Notes to Condensed Consolidated Financial Statements within this Quarterly Report on Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES

(a)Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rules 13a-15(e) and 15d-15(e), that are designed to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Any system of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Management of the Company, with the participation of the principal executive officer and the principal financial officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 30, 2024. Based on the evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2024.

(b) Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting as defined in the Exchange Act Rules 13a-15(f) and 15d-15(f) that occurred during the three months ended June 30, 2024, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The information presented in Note 18, Commitments and Contingencies, to our Condensed Consolidated Financial Statements is incorporated herein by reference.

Item 1A. Risk Factors

The business, financial condition and operating results of the Company can be affected by a number of factors, whether currently known or unknown, including but not limited to those described in Part I, Item 1A of the Company's Annual Report on Form 10-K for the year ended December 31, 2023, under the heading “Risk Factors,” any one or more of which could, directly or indirectly, cause the Company’s actual financial condition and operating results to vary materially from past, or from anticipated future, financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect the Company’s business, financial condition, operating results and stock price. There have been no material changes to the Company’s risk factors from those set forth in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 4, 2024.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Cost of Services	Cost of Services Cost of services consists of third-party contractor costs related to the delivery of various services in the Company's On-Demand Talent and Heidrick Consulting operating segments.
Research and Development	Research and Development Research and development expense consists of payroll, employee benefits, stock-based compensation, other employee expenses and third-party professional fees associated with new product development.
Marketable Securities	Marketable Securities The Company’s marketable securities consist of available-for-sale debt securities with original maturities exceeding three months.
Earnings (Loss) per Common Share	Earnings (Loss) per Common Share Basic earnings (loss) per common share are computed by dividing net income (loss) by weighted average common shares outstanding for the period. Diluted earnings (loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings (loss) per share in periods in which they have an anti-dilutive effect.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets, Current liabilities - Operating lease liabilities and Non-current liabilities - Operating lease liabilities in the Company's Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria. Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. For office leases, the Company accounts for the lease and non-lease components as a single lease component. For equipment leases, such as vehicles and office equipment, the Company accounts for the lease and non-lease components separately.
Goodwill	Goodwill Goodwill represents the difference between the purchase price of acquired businesses and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of its goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. These circumstances include a significant change in business climate, attrition of key personnel, changes in financial condition or results of operations, prolonged decline in the Company’s stock price and market capitalization, competition, and other factors. The goodwill impairment test compares the fair value of a reporting unit to its carrying amount, including goodwill. The Company operates five reporting units: Americas, Europe (which includes Africa), Asia Pacific (which includes the Middle East), On-Demand Talent and Heidrick Consulting. The fair value of each of the Company’s reporting units is determined using a discounted cash flow methodology. An impairment charge is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit. As a result of triggering events, the Company performed interim goodwill impairment evaluations during the three months ended June 30, 2024, and 2023, when the Company determined that it was more likely than not that the fair value of at least one of its reporting units was less than its respective carrying amount. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions to evaluate the impact of operating and macroeconomic changes on each reporting unit. During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. The discounted cash flow approach is dependent on a number of factors, including estimates of future market growth and trends, forecasted revenue and costs, capital investments, appropriate discount rates, certain assumptions to allocate shared costs, assets and liabilities, historical and projected performance of the reporting unit, and the macroeconomic conditions affecting each of the Company’s reporting units. The assumptions used in the determination of fair value were (1) a forecast of growth in the near and long term; (2) the discount rate; (3) working capital investments; (4) macroeconomic conditions; and (5) other factors. As part of the goodwill impairment evaluation, the Company performed a reconciliation of its market capitalization to the aggregated estimated fair value of all reporting units, including consideration of a control premium. Based on the results of the 2024 impairment evaluation, the Company determined that the goodwill within the On-Demand Talent and Europe reporting units were impaired, which resulted in impairment charges of $14.8 million and $1.5 million, respectively. Based on the results of the 2023 impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million. The impairment charges are recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income (Loss) for the three and six months ended June 30, 2024, and 2023 and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2024, and 2023. The impairments were non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations; nor did they impact the debt covenants under the Company's credit agreement.
Recently Issued Financial Accounting Standards	Recently Issued Financial Accounting Standards In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." The standard is intended to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its financial statements. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The standard is intended to improve reportable segment disclosure requirements for public business entities primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit (referred to as the “significant expense principle”). This guidance is effective for annual periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The Company is currently evaluating the impact of this guidance on its financial statements. In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance was intended to provide temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. This guidance is effective March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2024. The new guidance is not expected to have a material effect on the Company's financial statements.
Revenue Recognition	Executive Search Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Generally, each executive search contract contains one performance obligation which is the process of identifying potentially qualified candidates for a specific client position. In most contracts, the transaction price includes both fixed and variable consideration. Fixed compensation is comprised of a retainer, equal to approximately one-third of the estimated first year compensation for the position to be filled, and indirect expenses, equal to a specified percentage of the retainer, as defined in the contract. The Company generally bills clients for the retainer and indirect expenses in one-third increments over a three-month period commencing in the month of a client’s acceptance of the contract. If actual compensation of a placed candidate exceeds the original compensation estimate, the Company is often authorized to bill the client for one-third of the excess compensation. The Company refers to this additional billing as uptick revenue. In most contracts, variable consideration is comprised of uptick revenue and direct expenses. The Company bills its clients for uptick revenue upon completion of the executive search, and direct expenses are billed as incurred. The Company estimates uptick revenue at contract inception, based on a portfolio approach, utilizing the expected value method based on a historical analysis of uptick revenue realized in the Company’s geographic regions and industry practices, and initially records a contract’s uptick revenue in an amount that is probable not to result in a significant reversal of cumulative revenue recognized when the actual amount of uptick revenue for the contract is known. Differences between the estimated and actual amounts of variable consideration are recorded when known. The Company does not estimate revenue for direct expenses as it is not materially different than recognizing revenue as direct expenses are incurred. Revenue from executive search engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. Revenue from executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill the obligations under the executive search contract. Revenue is generally recognized over a period of approximately six months. The Company's executive search contracts contain a replacement guarantee which provides for an additional search to be completed, free of charge except for expense reimbursements, should the candidate presented by the Company be hired by the client and subsequently terminated by the client for performance reasons within a specified period of time. The replacement guarantee is an assurance warranty, which is not a performance obligation under the terms of the executive search contract, as the Company does not provide any services under the terms of the guarantee that transfer benefits to the client in excess of assuring that the identified candidate complies with the agreed-upon specifications. The Company accounts for the replacement guarantee under the relevant warranty guidance in Accounting Standards Codification 460 - Guarantees. On-Demand Talent The Company enters into contracts with clients that outline the general terms and conditions of the assignment to provide on-demand consultants for various types of consulting projects, which consultants may be independent contractors or temporary employees. The consideration the Company expects to receive under each contract is dependent on the time-based fees specified in the contract. Revenue from on-demand engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. The Company has applied the practical expedient to recognize revenue for these services in the amount to which the Company has a right to invoice the client, as this amount corresponds directly with the value provided to the client for the performance completed to date. For transactions where a third-party contractor is involved in providing the services to the client, the Company reports the revenue and the related direct costs on a gross basis as it has determined that it is the principal in the transaction. The Company is primarily responsible for fulfilling the promise to provide consulting services to its clients and the Company has discretion in establishing the prices charged to clients for the consulting services and is able to contractually obligate the independent service provider to deliver services and deliverables that the Company has agreed to provide to its clients. Heidrick Consulting Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Heidrick Consulting enters into contracts with clients that outline the general terms and conditions of the assignment to provide succession planning, executive assessment, top team and board effectiveness and culture shaping programs. The consideration the Company expects to receive under each contract is generally fixed. Most of the Company's consulting contracts contain one performance obligation, which is the overall process of providing the consulting service requested by the client. The majority of the Company's consulting revenue is recognized over time utilizing input methods. Revenue recognition over time for the majority of the Company's consulting engagements is measured by total cost or time incurred as a percentage of the total estimated cost or time on the consulting engagement. Contract Balances Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities are classified as current due to the nature of the Company's contracts, which are completed within one year. Contract assets are included within Other current assets on the Condensed Consolidated Balance Sheets. Unbilled receivables: Unbilled receivables represents contract assets from revenue recognized over time in excess of the amount billed to the client and the amount billed to the client is solely dependent upon the passage of time. This amount includes revenue recognized in excess of billed Executive Search retainers, Heidrick Consulting fees, and On-Demand Talent fees. Contract assets: Contract assets represent revenue recognized over time in excess of the amount billed to the client, and the amount billed to the client is not solely subject to the passage of time. This amount primarily includes revenue recognized for upticks and contingent placement fees in executive search contracts. Deferred revenue: Contract liabilities consist of deferred revenue, which is equal to billings in excess of revenue recognized.
