Altice and Teads say the acquisition rationale is the strategic combination of their assets — citing, for example, the advantage of being able to link Altice's "unique first party data-sets" (aka the personal data of the 50 million subscribers to its broadband and mobile services) with Teads' "relationships with 94 of the top 100 advertisers globally" and "partnerships with 500+ premium publishers globally and 8,000 vertically specialized publishers."
