Here are 1-3 brief analogies to describe Gran Tierra Energy (GTE):

• Like a smaller EOG Resources, but focused on conventional oil exploration and production in Latin America (mainly Colombia).

• Similar to Barrick Gold, but they explore for and produce oil in Latin America instead of gold globally.

• A significantly smaller ConocoPhillips, concentrated on conventional oil fields in Latin America.

• Crude Oil: Gran Tierra Energy explores for, develops, and produces crude oil primarily in Colombia and Ecuador for sale in international markets.
• Natural Gas: The company also produces natural gas, often in conjunction with oil production, which is sold to regional markets.

Gran Tierra Energy (GTE) is an oil and gas exploration and production company. As such, it sells its crude oil and natural gas primarily to other companies rather than directly to individuals.

According to Gran Tierra Energy's 2023 Annual Information Form, its major customers include:

• Ecopetrol S.A. (BVC: ECOPETROL, NYSE: EC) - This national oil company of Colombia accounted for approximately 53% of Gran Tierra Energy's total revenue in 2023.
• An international crude oil marketing and trading company - This unnamed company accounted for approximately 28% of Gran Tierra Energy's total revenue in 2023. Public companies often do not disclose the names of all significant customers, especially trading firms, due to commercial confidentiality.

Natural Gas

• Colombia:
  • The Colombian gas sector is a mature market, with consumption reported at 1.263 billion cubic feet per day (bcfd) in December 2023. Average gas demand over the past six years has been around 960 million cubic feet per day (MMcfd).
  • In 2020, domestic dry natural gas consumption in Colombia was 413 billion cubic feet (Bcf).
• Ecuador:
  • Ecuador's natural gas market is less developed compared to its oil sector.
  • In 2020, Ecuador's natural gas production was approximately 12 billion cubic feet per day. Marketed production was 310 million cubic meters (Cub m mn) in December 2023.

  • Latin America's annual natural gas consumption is projected to reach 275 billion cubic meters (Bm³) by 2050, up from approximately 150 Bm³ in 2023.

Natural Gas Liquids (NGLs)

  • The Natural Gas Liquids market in Latin America was valued at USD 877.11 million in 2024 and is projected to grow to USD 1361.5 million by 2031.
• Colombia:

• Increased Production from Development Drilling: Gran Tierra Energy has outlined plans to significantly increase its production through an active development drilling program. For 2025, the company forecasts production of 47,000-53,000 barrels of oil equivalent per day (BOEPD), representing a 44% increase from 2024 production levels at the midpoint. This includes drilling 10 to 14 net development wells, with a focus on the Cohembi oil field in Colombia's Suroriente block (5-7 gross wells) and continuing appraisal programs in Ecuador, particularly in the highly prospective Arawana/Zabaleta productive trend (2-3 appraisal wells).
• High-Impact Exploration Success: The company is allocating a significant portion of its capital program (20-30% in 2025) to high-impact exploration activities, with plans to drill 6 to 8 exploration wells in Colombia and Ecuador. Recent successes, such as the Conejo A-1 and A-2 wells and a new discovery at Chanangue-1 in Ecuador, are expected to transition into development phases, further boosting production. The fulfillment of exploration commitments in Ecuador in 2025 positions the company to focus on increasing production into the development phase for long-term growth in the region.
• Enhanced Oil Recovery (EOR) and Field Optimization: Gran Tierra is committed to optimizing its existing assets through continued waterflood expansion activities and gas-to-power generation upgrades. Notably, the Cohembi waterflood project has already demonstrated significant success, more than doubling output, and total field production recently exceeded 9,000 barrels per day. These efforts aim to reduce unit costs, offset natural declines, and increase overall recovery from mature fields like Acordionero.
• Strategic Acquisitions and Portfolio Longevity: The strategic acquisition in Canada contributed to a substantial increase in Q3 2025 production. Gran Tierra's ongoing strategy involves profitably growing reserves and production across its diversified asset base in Colombia, Ecuador, and Canada, pursuing new growth opportunities, and investing in infrastructure projects to maximize long-term value. The company's focus on portfolio longevity and a robust portfolio of conventional and unconventional oil and gas assets are expected to sustain future growth.
