AutoAlliance (Thailand) Co., Ltd. (AAT) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from AutoAlliance Thailand (Wikipedia), AutoAlliance (Thailand) Co., Ltd. company website and Production Facility in Thailand, AutoAlliance (Thailand), Celebrates its 25th Anniversary (Mazda Newsroom). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of AutoAlliance (Thailand) Co., Ltd. (AAT) where a holder stated one, and are missing where no holder did.
