Who owns Amber International Holding?
Amber International Holding trades in the U.S. through ADRs, certificates that represent shares of a non-U.S. company. Form 13F counts ADRs while the company reports ordinary shares, so we do not compute percentages. Holders reporting more than 5% of the ordinary shares to the SEC (Schedules 13D/13G): Yuao Wu (Michael), 76.4% (13D filed Mar 19, 2025), Yuao Wu, 19.1% (13D/A filed Oct 28, 2026), HSG Holding, 9.5% (13G filed Jun 17, 2026), Temasek Holdings (Private), 7.1% (13G filed Jun 5, 2026) and Paradigm Fund, 7.1% (13G filed Jun 5, 2026).

The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.
Insiders (Form 4)
Open-market purchases, excluding 10b5-1 plans. Officers and directors only; joint filers of the same purchase count as one. 10% owners with no role are shown separately. 0 = nobody bought; “no data” = we do not have its Form 4 filings.

This list may be incomplete: we hold 13D and 13G filings made since Dec 23, 2024. A holder above 5% that has not filed anything since then is not shown here.

This company filed no 8-K forms in the last year. Foreign companies listed in the US (ADRs) report material events on forms 6-K and 20-F, and ETFs and funds do not file 8-Ks. If it is a foreign company listed in the US through ADRs (American Depositary Receipts), what trades are bank-issued certificates that represent shares from its home market.
