Promotora de Partes Electricas Automotrices, S.A. de C.V. 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 Resolution CNT-18-99, Promotora de Partes Electricas Automotrices / Gabriel de Mexico (Comision Federal de Competencia), Cableando el norte de Mexico: la evolucion de la industria maquiladora de arneses (Region y Sociedad, SciELO) and Aptiv PLC 2024 Form 10-K, Exhibit 21.1 list of subsidiaries (SEC). 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.
- Aptiv PLC. A Mexican equity-method affiliate named in the FY2025 10-K's list of Aptiv's three most significant equity-method investments (alongside Motional and StradVision), but with no individually itemized carrying value: the 10-K discloses only a single combined 'aggregate investments in affiliates' balance covering Motional, StradVision, this entity and any other smaller affiliates. Per this project's rule against assigning a combined balance to one investee, value_usd is left null. The Q2 2026 10-Q does not mention this entity by name at all (only Motional, StradVision, TTTech Auto and Maxieye are discussed), and the itemized Motional ($1,121m) plus StradVision ($134m) carrying values sum EXACTLY to the 30 Jun 2026 consolidated 'investments in affiliates' balance of $1,255 million, implying this holding's carrying value was immaterial (effectively at or near zero) as of that date; the 40% ownership percentage itself is not stated to have changed and is carried forward from the FY2025 10-K (period 31 Dec 2025) as the latest sourced figure. sourcesource 2
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 Promotora de Partes Electricas Automotrices, S.A. de C.V. where a holder stated one, and are missing where no holder did.
