When did Daniel Lau buy into Gran Tierra Energy Inc.?
The filings give report dates, not purchase dates. The earliest filing from Daniel Lau on this page is the Schedule 13G/A, filed 2025-11-14, reporting 9%; its latest, Schedule 13G/A filed 2026-08-12, reports 13.6%. 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%); 12 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.
