Shanghai OnStar Telematics Co., Ltd. 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 GM, SAIC and OnStar Announce China Telematics JV (The Auto Channel, 2007), Shanghai OnStar Breaks the 200,000th Subscriber Mark (PR Newswire, 25 February 2011) and General Motors Form 10-K Exhibit 21, subsidiaries and joint ventures as of 31 December 2025. 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.
- General Motors Company. FY2025 10-K China JV ownership table: 'Shanghai OnStar Telematics Co., Ltd. (Shanghai OnStar) 40%' direct GM interest at both 31 Dec 2025 and 31 Dec 2024; the 10-K separately notes 'SGM also has interests in Shanghai OnStar (20%)', i.e. SGM (itself 50% GM-owned) holds a further 20% of Shanghai OnStar, making GM's total look-through economic interest larger than the 40% direct figure recorded here.

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 Shanghai OnStar Telematics Co., Ltd. where a holder stated one, and are missing where no holder did.
