SEC Filing Summary

Ernst Teunissen, a director at Criteo S.A., reported a series of transactions on July 29, 2026, involving Ordinary Shares. On this date, 12,471 shares were disposed of, followed by the acquisition of 12,471 shares. Following these transactions, the post-transaction shares owned are reported as 0 and then 12,471 respectively. These transactions occurred in conjunction with Criteo S.A.'s conversion from a French public limited liability company to a Luxembourg public limited liability company. This conversion, effective July 29, 2026, resulted in the mandatory exchange of American Depositary Shares (ADSs) for Ordinary Shares. The filing also notes a correction to a previous filing due to a rounding error, adjusting the beneficial ownership amount. Footnote F1 clarifies that prior to conversion, Ordinary Shares may have been represented by ADSs, each representing one Ordinary Share, which were mandatorily exchanged at a one-to-one ratio. Footnote F2 provides details on the conversion, stating that all rights attached to equity awards remain unchanged, except for the right to receive shares of the new Luxembourg entity. Footnote F4 corrects a previous understatement of beneficial ownership by three shares due to a rounding error.
