Who owns Mattel

Mattel disclosed 16 subsidiaries in the 10-K it filed on 2026-02-23. Nothing here is Haven's inference — it is the company's own filing, and you can read it yourself.

Mattel lists only its significant subsidiaries. Regulation S-K lets a filer leave out entities that are immaterial in aggregate, so this is not the whole corporate family — it is the part the company had to disclose.

Names that are not Mattel's own

Entities in the filing that do not carry the Mattel name. These are usually the acquisitions — the brands most people do not know are connected.

Entities carrying the Mattel name

Regional operating and financing companies. Listed so the record can be checked rather than taken on trust.
