[425] Criteo S.A. Business Combination Communication

Rhea-AI Filing Summary

Criteo (CRTO) plans a strategic redomiciliation, moving its home jurisdiction to Luxembourg and replacing its ADS structure with a direct listing of ordinary shares on Nasdaq. Management says this aims to simplify legal complexity, enhance capital allocation flexibility, and broaden the shareholder base, including positioning for potential inclusion in major US stock indices.

The company expects completion in the third quarter of 2026, subject to the prior consultation of Criteo’s works council and shareholder approval. A subsequent move to the United States is intended, potentially as early as the first quarter of 2027, to further expand access to US capital markets. Leadership stated they do not see any material costs related to the process and intend to isolate related costs in reporting. Forward‑looking statements and risks were outlined, and a Form S‑4 with proxy/prospectus materials is expected for shareholder consideration.

Capital markets and governance analyst

CRTO outlines a two-step domicile shift with stated structural benefits.

Criteo plans to redomicile to Luxembourg with a direct Nasdaq listing of ordinary shares, replacing ADSs. Management cites simpler legal mechanics, greater flexibility in capital allocation, and a broader investor base, including potential eligibility for major US indices.

The timeline targets Q3 2026 for the Luxembourg step, subject to works council consultation and shareholder approval, with an intended US redomiciliation potentially by Q1 2027. Leadership said they do not see material costs and will separately disclose related items.

Risks disclosed include failure to secure shareholder approval, thresholds tied to withdrawal rights, listing contingencies, legal or regulatory actions, and possible costs or taxes. Actual impact depends on approvals and execution across the stated milestones.

The following excerpts relating to the intended redomiciliation are transcribed from the company’s Q3 2025 earnings call.

Michael Komasinski: * * * This morning, we also announced our intention to redomicile Criteo to Luxembourg and replace our current ADS structure with a direct listing of our ordinary shares on Nasdaq. We view this as an important strategic step toward unlocking significant and sustainable shareholder value, which reflects our commitment to ensuring Criteo has the optimal corporate structure. It is expected to offer significant advantages over our existing structure, including eliminating most of the legal complexities currently applicable to Criteo, enhancing flexibility in capital allocation, and broadening our shareholder base, and Sarah will provide additional details on this shortly. * * *

Sarah Glickman: * * * Before I close, I’d like to touch briefly on our intention to redomicile to Luxembourg and list our ordinary shares directly on Nasdaq. This change is designed to enhance our capital management flexibility, eliminating restrictions that Criteo currently faces in relation to share repurchases and position us for potential inclusion in major US stock indices. We believe it would expand our access to passive capital, triggering associated benchmarking from actively managed funds and broadening our shareholder base. We expect this process to be completed in the third quarter of 2026 subject to the prior consultation of Criteo’s works council and shareholder approval. Looking ahead, we intend to pursue a subsequent redomiciliation to the United States potentially as early as the first quarter of 2027 to further broaden our access to US capital markets. * * *

* * *

Tim Nollen: * * * as you move your domicile to Luxembourg and into the U.S., are there any financial implications we should be aware of, the cost to do this, the tax implications, reporting, anything like that? * * *

Sarah Glickman: * * * we don’t see any material costs related to that. And we will isolate those within our findings so you can see what those costs are. * * *
