Criteo S A : Investor Presentation Q3 2023

This presentation contains "forward-looking" statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that are based on our management's beliefs and assumptions and on information currently available to them. All statements other than present and historical facts and conditions contained in this presentation, including statements regarding our possible or assumed future results of operations and financial position, plans and objectives for future operations, business strategies, financing plans, projections, competitive position, industry environment, potential growth opportunities, potential market opportunities, potential acquisition opportunities, expected growth in commerce media and advertising spend generally, and the effects of competition and other actions by our counterparties, are forward-looking statements. Importantly, at this time, there is still uncertainty regarding the integration of our acquisitions of IPONWEB and Brandcrush and the timing and scope of proposed changes to and enhancements of the Chrome browser announced by Google. In addition, macroeconomic conditions including inflation and rising interest rates in the U.S. have impacted Criteo's business, financial condition, cash flow and results of operations. The dynamic nature of the aforementioned circumstances, among other matters, means that what is said in this presentation could materially change at any time.

Forward-looking statements include all statements that are not historical facts and can be identified by terms such as "anticipates," "believes," "can," "could," "estimates," "expects" "intends," "is designed to," "may," "might," "objectives," "plans," "potential," "predicts," "projects," "seeks," "should," "will," "would" or similar expressions and the negatives of those terms. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Forward-looking statements represent our management's beliefs and assumptions only as of the date of this presentation, and nothing in this presentation should be regarded as a representation by any person that these beliefs or assumptions will take place or occur. You should read the Company's most recent Annual Report on Form 10-K filed on February 24, 2023, and in subsequent Quarterly Reports on Form 10-Q, including the Risk Factors set forth therein and the exhibits thereto, as well as future filings and reports by the Company, completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future.

This presentation includes certain non-GAAP financial measures as defined by SEC rules, including forward-looking measures. As required by Regulation G, we have provided a reconciliation of those measures to the most directly comparable GAAP measures, which is available in the Appendix slides. Reconciliations also are available in our earnings release for the third quarter 2023, which is available on our website at www.criteo.com. Reconciliations of our forward-lookingnon-GAAP measures to the closest corresponding GAAP measure are not available without reasonable efforts due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures, which could have a potentially significant impact on our future U.S. GAAP results.
