Daniel Lau bought GTE once, on Dec 18, 2025

Daniel Lau is a director and 10% beneficial owner of Gran Tierra Energy Inc. (GTE), a publicly traded oil and gas exploration and production company.( He first reported his insider ownership on a Section 16 Form 3 filing, disclosing direct holdings of 240,000 common shares of Gran Tierra Energy and additional indirect holdings through private investment funds and companies where he is a director and controlling shareholder.( Subsequent Form 4 disclosures show that Lau has been an active net buyer of GTE stock; on December 18, 2025, he purchased 360,000 additional common shares at a weighted average price of approximately $3.95 per share, bringing his reported beneficial ownership to over 3.9 million shares held directly and indirectly.( In these filings, he disclaims beneficial ownership of certain indirectly held securities except to the extent of his pecuniary interest, consistent with standard U.S. securities law practice for control persons of investment entities.(

Lau’s indirect holdings are primarily structured through private investment funds managed by an investment advisory firm for which he is a control person, as well as companies where he serves as a director and controlling shareholder, underscoring his role as a sophisticated institutional investor and significant stakeholder in Gran Tierra Energy.( Public filings and insider trading databases identify him specifically as an individual large shareholder/10% owner rather than a corporate entity, and his trading record in GTE reflects a concentrated focus on this single issuer.( Detailed information about his broader career background and education is not provided in the available SEC-related and market data sources, which primarily document his governance role at Gran Tierra Energy and his substantial equity ownership position.(
