First Quarter 2024 Results

Revenue, Gross Profit and Contribution ex-TAC

Revenue increased by 1% year-over-year in Q1 2024, or 3% at constant currency, to $450 million (Q1 2023: $445 million). Gross profit increased by 20% year-over-year in Q1 2024 to $217 million (Q1 2023: $182 million). Gross profit as a percentage of revenue, or gross profit margin, was 48% (Q1 2023: 41%). Contribution ex-TAC in the first quarter increased 15% year-over-year, or increased 17% at constant currency, to $254 million (Q1 2023: $221 million).

•Retail Media revenue increased 34%, or 33% at constant currency, reflecting continued strength in Retail Media onsite. Retail Media Contribution ex-TAC increased 34%, or 34% at constant currency, driven by continued strength in Retail Media onsite, new client integrations and growing network effects of the platform.

•Performance Media revenue was down 2%, or flat at constant currency, and Performance Media Contribution ex-TAC increased 11%, or increased 13% at constant currency, driven by the continued traction of Commerce Audiences as more clients adopt full funnel activation.

Net Income (Loss) and Adjusted Net Income

Net income was $9 million in Q1 2024 (Q1 2023: net loss of $12 million). Net income allocated to shareholders of Criteo was $7 million, or $0.12 per share on a diluted basis (Q1 2023: net loss available to shareholders of $12 million, or $0.21 per share on a diluted basis).

Adjusted net income, a non-GAAP financial measure, was $47 million, or $0.80 per share on a diluted basis (Q1 2023: $28 million, or $0.50 per share on a diluted basis).

Adjusted EBITDA and Operating Expenses

Adjusted EBITDA was $71 million, representing an increase of 83% year-over-year (Q1 2023: $39 million). This reflects higher Contribution ex-TAC over the period and effective cost management. Adjusted EBITDA as a percentage of Contribution ex-TAC, or Adjusted EBITDA margin, was 28% (Q1 2023: 18%).

Operating expenses increased by 1% year-over-year to $207 million (Q1 2023: $205 million), mostly driven by planned growth investments partially offset by cost efficiencies. Non-GAAP operating expenses were flat at $155 million (Q1 2023: $155 million).

Cash Flow, Cash and Financial Liquidity Position

Cash flow from operating activities was $14 million in Q1 2024 (Q1 2023: $42 million).

Free Cash Flow, defined as cash flow from operating activities less acquisition of intangible assets, property, plant and equipment and change in accounts payable related to intangible assets, property, plant and equipment, was $1 million in Q1 2024 (Q1 2023: $9 million).

Cash and cash equivalents, and marketable securities, decreased $70 million compared to December 31, 2023 to $289 million, after spending $62 million on share repurchases in the first three months of 2024.

As of March 31, 2024, the Company had total financial liquidity of approximately $805 million, including its cash position, marketable securities, revolving credit facility and treasury shares reserved for M&A.

2024 Business Outlook

The following forward-looking statements reflect Criteo’s expectations as of May 2, 2024.

Fiscal year 2024 guidance:

•We now expect Contribution ex-TAC to grow high-single-digit at constant currency, compared to our previous guidance of mid-single-digit growth at constant currency.

•We now expect an Adjusted EBITDA margin of approximately 31% of Contribution ex-TAC, compared to our previous guidance of 29% to 30% of Contribution ex-TAC.

Second quarter 2024 guidance:

•We expect Contribution ex-TAC between $261 million and $265 million, or year-over-year growth at constant-currency of +10% to +12%.

•We expect Adjusted EBITDA between $70 million and $74 million.

The guidance for the second quarter and fiscal year ending December 31, 2024 assumes the following exchange rates for the main currencies impacting our business: a U.S. dollar-euro rate of 0.915, a U.S. dollar-Japanese Yen rate of 149, a U.S. dollar-British pound rate of 0.785, a U.S. dollar-Korean Won rate of 1,342 and a U.S. dollar-Brazilian real rate of 4.95.

The guidance assumes that no additional acquisitions are completed during the second quarter of 2024 or the fiscal year ended December 31, 2024.

Reconciliations of Contribution ex-TAC, Adjusted EBITDA and Adjusted EBITDA margin guidance to the closest corresponding U.S. GAAP measures are not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures; in particular, the measures and effects of equity awards compensation expense specific to equity compensation awards that are directly impacted by unpredictable fluctuations in our share price. The variability of the above charges could potentially have a significant impact on our future U.S. GAAP financial results.

Non-GAAP Financial Measures

This press release and its attachments include the following financial measures defined as non-GAAP financial measures by the U.S. Securities and Exchange Commission ("SEC"): Contribution ex-TAC, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted diluted EPS, Free Cash Flow and Non-GAAP Operating Expenses. These measures are not calculated in accordance with U.S. GAAP.

Contribution ex-TAC is a profitability measure akin to gross profit. It is calculated by deducting traffic acquisition costs from revenue and reconciled to gross profit through the exclusion of other costs of revenue. Contribution ex-TAC is not a measure calculated in accordance with U.S. GAAP. We have included Contribution ex-TAC because it is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions. In particular, we believe that this measure can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Contribution ex-TAC provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Adjusted EBITDA is our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, and certain acquisition costs. Adjusted EBITDA and Adjusted EBITDA margin are key measures used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. In particular, we believe that Adjusted EBITDA and Adjusted EBITDA margin can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors and the market generally in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Adjusted Net Income is our net income adjusted to eliminate the impact of equity awards compensation expense, amortization of acquisition-related assets, certain restructuring, integration and transformation costs, certain acquisition costs, and the tax impact of these adjustments. Adjusted Net Income and Adjusted diluted EPS are key measures used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that Adjusted Net Income and Adjusted diluted EPS can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted Net Income and Adjusted diluted EPS provide useful information to investors and the market generally in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Free Cash Flow is defined as cash flow from operating activities less acquisition of intangible assets, property, plant and equipment and change in accounts payable related to intangible assets, property, plant and equipment. Free Cash Flow Conversion is defined as free cash flow divided by Adjusted EBITDA. Free Cash Flow and Free Cash Flow Conversion are key measures used by our management and board of directors to evaluate the Company's ability to generate cash. Accordingly, we believe that Free Cash Flow and Free Cash Flow Conversion permit a more complete and comprehensive analysis of our available cash flows.

Non-GAAP Operating Expenses are our consolidated operating expenses adjusted to eliminate equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, and certain acquisition and integration costs. The Company uses Non-GAAP Operating Expenses to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short-term and long-term operational plans, and to assess and measure our financial performance and the ability of our operations to generate cash. We believe Non-GAAP Operating Expenses reflects our ongoing operating expenses in a manner that allows for meaningful period-to-period comparisons and analysis of trends in our business. As a result, we believe that Non-GAAP Operating Expenses provides useful information to investors in understanding and evaluating our core operating performance and trends in the same manner as our management and in comparing financial results across periods. In addition, Non-GAAP Operating Expenses is a key component in calculating Adjusted EBITDA, which is one of the key measures the Company uses to provide its quarterly and annual business outlook to the investment community.

Please refer to the supplemental financial tables provided in the appendix of this press release for a reconciliation of Contribution ex-TAC to gross profit, Adjusted EBITDA to net income, Adjusted Net Income to net income, Free Cash Flow to cash flow from operating activities, and Non-GAAP Operating Expenses to operating expenses, in each case, the most comparable U.S. GAAP measure. Our use of non-GAAP financial measures has limitations as an analytical tool, and you should not consider such non-GAAP measures in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: 1) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; and 2) other companies may report Contribution ex-TAC, Contribution ex-TAC margin, Adjusted EBITDA, Adjusted Net Income, Free Cash Flow, Non-GAAP Operating Expenses or similarly titled measures but calculate them differently or over different regions, which reduces their usefulness as comparative measures. Because of these and other limitations, you should consider these measures alongside our U.S. GAAP financial results, including revenue and net income.

(1) The Retail Media Platform, introduced in June 2020, is a strategic building block of Criteo’s Commerce Media Platform and is reported under the retail media segment. It is a self-service solution providing transparency, measurement and control to brands and retailers. In all arrangements running on this platform, Criteo recognizes revenue on a net

basis, whereas revenue from arrangements running on legacy Retail Media solutions were accounted for on a gross basis.
