Questions about who owns Burning Rock Biotech Ltd
Who owns Burning Rock Biotech Ltd?
On this page, one holder's latest ownership filing reports 5% or more of Burning Rock Biotech Ltd: Kynam Capital Management, LP (13.97%, Schedule 13G/A, filed 2026-05-15).
When did Kynam Capital Management, LP buy into Burning Rock Biotech Ltd?
The filings give report dates, not purchase dates. The earliest filing from Kynam Capital Management, LP on this page is the Schedule 13G/A, filed 2025-11-14, reporting 11.01%; its latest, Schedule 13G/A filed 2026-05-15, reports 13.97%. That earliest filing is itself an amendment, which updates an earlier report.
Is this an audit or a full list?
Neither. The ownership list on this page covers only Schedule 13D and 13G filings, which holders make once they own 5% or more of a class of shares (an amendment can report a stake that has since fallen below 5%); 4 such filings are shown here. It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
