Gran Tierra Energy Inc.
An oil and gas explorer that finds and produces crude oil and natural gas from underground reserves, Gran Tierra has long been a major presence in South America's fields. Headquartered in Calgary, Alberta, the firm was renamed in 2005 during a share exchange and has built its business around wells in Colombia, Ecuador, and Canada. Its Spanish name "Gran Tierra" simply means "Great Land" — a fitting nod to the terrain beneath its drilling sites.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: +4.09M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
