2023 Third Quarter Results

Consolidated net revenue was $263.2 million in the 2023 third quarter compared to consolidated net revenue of $255.2 million in the 2022 third quarter. The Company experienced growth in On-Demand Talent, Heidrick Consulting, and Executive Search in Europe, partially offset by declines in Executive Search in Asia Pacific and the Americas.

On a sequential basis, 2023 third quarter operating income was $22.1 million compared to $13.6 million in the 2023 second quarter. Adjusted operating income was $22.1 million compared to $20.8 million in the 2023 second quarter, and adjusted operating margin was 8.4% compared to 7.7% in the 2023 second quarter. Adjusted operating income in the 2023 second quarter reflects the exclusion of a non-cash impairment charge of $7.2 million. Adjusted EBITDA was $32.3 million in the 2023 third quarter compared to $36.4 million in the 2023 second quarter, and 2023 third quarter adjusted EBITDA margin was 12.3% compared to 13.4% in the 2023 second quarter. 2023 third quarter net income was $15.0 million compared to $9.0 million in the 2023 second quarter. This generated diluted earnings per share in the 2023 third quarter of $0.73, compared to $0.44 in the 2023 second quarter. Adjusted net income of $15.0 million and adjusted diluted earnings per share of $0.73 in the 2023 third quarter were consistent with 2023 second quarter results.

Executive Search net revenue was $198.8 million compared to net revenue of $212.8 million in the 2022 third quarter reflecting a decrease in the volume of executive search confirmations. Net revenue decreased 7.9%, or $16.8 million on a constant currency basis from the 2022 third quarter. Net revenue decreased 7.9% in the Americas (down 8.1% on a constant currency basis), increased 8.4% in Europe (up 1.0% on a constant currency basis), and decreased 21.6% in Asia Pacific (down 19.8% on a constant currency basis) when compared to the prior year third quarter.

The Company had 417 Executive Search consultants at September 30, 2023, compared to 389 at September 30, 2022. Productivity, as measured by annualized Executive Search net revenue per consultant, was $1.9 million compared to $2.2 million in the 2022 third quarter, reflecting a higher number of consultants combined with lower

revenue. Average revenue per executive search was approximately $153,000 compared to $155,000 in the prior year period. The number of search confirmations decreased 5.1% compared to the year-ago period.

On-Demand Talent net revenue was $41.1 million, an increase of 76.6% compared to net revenue of $23.2 million in the 2022 third quarter, primarily due to the acquisition of Atreus Group GmbH (“Atreus”), partially offset by a decrease in the volume of legacy on-demand projects.

Heidrick Consulting net revenue was $23.3 million compared to net revenue of $19.1 million in the 2022 third quarter due to organic growth coupled with the acquisition of businessfourzero. The Company had 90 Heidrick Consulting consultants at September 30, 2023, compared to 72 at September 30, 2022.

Consolidated salaries and benefits decreased $4.3 million, or 2.5%, to $167.2 million compared to $171.5 million in the 2022 third quarter. Year-over-year, fixed compensation expense increased $9.2 million due to increases in base salaries and payroll taxes, expenses related to the deferred compensation plan, separation costs, and talent acquisition and retention costs, partially offset by decreases in stock compensation, and retirement and benefits. Variable compensation decreased $13.5 million due to lower bonus accruals related to decreased consultant productivity. Salaries and benefits expense was 63.5% of net revenue for the quarter compared to 67.2% in the 2022 third quarter.

General and administrative expenses increased $5.4 million, or 16.7%, to $37.6 million compared to $32.2 million in the 2022 third quarter. The increase was due to intangible amortization and accretion, increases in expenses related to office occupancy, and marketing, as well as the acquisitions of Atreus and businessfourzero, partially offset by a decrease in business development travel. As a percentage of net revenue, general and administrative expenses were 14.3% for the 2023 third quarter compared to 12.6% in the 2022 third quarter.

The Company’s cost of services was $30.7 million, or 11.7% of net revenue for the quarter, compared to $17.8 million, or 7.0% of net revenue in the 2022 third quarter. This related to an increase in the volume of On-Demand Talent projects driven by the acquisition of Atreus.

The Company’s research and development expenses were $5.6 million, or 2.1% of net revenue for the quarter compared to $5.4 million, or 2.1%, of net revenue for the third quarter 2022.

Operating income was $22.1 million for the quarter compared to $28.3 million in the 2022 third quarter. Operating income margin was 8.4% versus 11.1% in the 2022 third quarter. Adjusted operating income in the 2023 third quarter was $22.1 million and adjusted operating income margin was 8.4% compared to 2022 third quarter adjusted operating income of $27.8 million and adjusted operating margin of 10.9%. Adjusted operating income in the 2022 third quarter reflects an adjustment to exclude a reduction in the fair value of an On-Demand Talent earnout by $0.5 million.

Adjusted EBITDA was $32.3 million compared to $33.3 million in the 2022 third quarter. Adjusted EBITDA margin was 12.3%, compared to 13.0% in the 2022 third quarter. In Executive Search, adjusted EBITDA was $51.9 million compared to $51.5 million in the prior year period. In On-Demand Talent, adjusted EBITDA was a loss of $0.6 million versus income of $0.2 million in the prior year period. In Heidrick Consulting, adjusted EBITDA was a loss of $2.2 million compared to a loss of $5.2 million in the prior year period.

Net income was $15.0 million and diluted earnings per share was $0.73, with an effective tax rate of 37.5%. This compares to net income of $20.8 million and diluted earnings per share of $1.02, with an effective tax rate of 29.5% in the 2022 third quarter. Adjusted net income was $15.0 million and adjusted diluted earnings per share was $0.73, with an adjusted effective tax rate of 37.5% compared to 2022 third quarter adjusted net income of $20.5 million and adjusted diluted earnings per share of $1.00, which reflects the aforementioned earnout fair value adjustment.

Net cash provided by operating activities was $109.5 million, compared to $138.5 million in the 2022 third quarter. Cash, cash equivalents and marketable securities at September 30, 2023 was $334.0 million compared to $456.0 million at September 30, 2022 and $621.6 million at December 31, 2022. The Company’s cash position typically builds throughout the year as employee bonuses are accrued, mostly to be paid out in the first half of the year.

Dividend

The Board of Directors declared a 2023 fourth quarter cash dividend of $0.15 per share payable on November 21, 2023, to shareholders of record at the close of business on November 7, 2023.

2023 Fourth Quarter Outlook

The Company expects 2023 fourth quarter consolidated net revenue of between $240 million and $260 million, which may be impacted by external factors, such as the foreign exchange and interest rate environments, foreign conflicts, inflation and macroeconomic constraints on pricing actions. In addition, this outlook is based on the average currency rates in September 2023 and reflects, among other factors, management's assumptions for the anticipated volume of new Executive Search confirmations, On-Demand Talent projects, and Heidrick Consulting assignments, consultant productivity, consultant retention, and the seasonality of the business along with the current backlog.

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 operating income, adjusted operating income margin, adjusted net income, adjusted diluted earnings per share, adjusted effective tax rate, adjusted EBITDA, adjusted EBITDA margin, and consolidated 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 trends. 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 operating income is operating income excluding goodwill impairment and earnout fair value adjustments.

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

Adjusted net income and adjusted diluted earnings per share are net income and diluted earnings per share excluding goodwill impairment and earnout fair value adjustments, net of tax.

Adjusted effective tax rate is effective tax rate excluding goodwill impairment and earnout fair value adjustments, net of tax.

Adjusted EBITDA refers to earnings before interest, taxes, depreciation, intangible amortization, equity-settled stock compensation expense, earnout accretion, earnout fair value adjustments, acquisition contingent compensation,

deferred compensation plan income and expense, reorganization costs, impairment charges, restructuring charges, and other non-operating income (expense).

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.
