Risk factors and legal proceedings
The risks Gran Tierra Energy names in Item 1A of its 10-K filed Mar 4, 2026: 28 risks under these headings, as written.88
- Risks Related to our Business
- Prices and markets for oil and natural gas are unpredictable and tend to fluctuate significantly, which could cause temporary suspension of production and reduce our value
- Estimates of oil and natural gas reserves may be inaccurate and our actual revenues may be lower than estimated
- Unless we are able to replace our reserves and production, and develop and manage oil and natural gas reserves and production on an economically viable basis, our financial condition and results of operations will be adversely impacted
- Exploration for oil and natural gas, and development of new formations, is risky
- Drilling activities may encounter sour gas
- Possible shortage of fresh water and surface and groundwater licenses
- Crown land tenure obligations, interpretations and freehold offset royalty obligations
- Unforeseen title defects
- Indigenous rights and stakeholder opposition in Canada
- Restrictions on development activities to protect wildlife
- Joint Venture partner alignment
The other 20 risks
- We are vulnerable to risks associated with geographically concentrated operations
- Social disruptions or community disputes in Colombia and Ecuador may delay production and result in lost revenue
- Security concerns in Colombia, Ecuador or Azerbaijan may disrupt our operations
- A substantial portion of our revenue is generated outside of Canada and the United States, and if we determine to, or are required to, repatriate earnings from foreign jurisdictions, we could be subject to taxes
- Certain acquisitions could adversely affect our financial results
- The threat and impact of cybersecurity incidents may adversely impact our operations and could result in information theft, data corruption, operational disruption, and/or financial loss
- We may be adversely affected by global epidemics or public health crises
- Risks Related to our Financial Condition
- Our business requires significant capital expenditures, and we may not have the resources necessary to fund these expenditures
- Public and investor sentiment towards climate change, fossil fuels and other sustainability and human capital matters could adversely affect our cost of capital and the price of our common stock
- Anti-greenwashing rules introduce risk into making certain environmental-related disclosures
- Foreign currency exchange rate volatility may affect our financial results
- Legal and Regulatory Risks
- We are dependent on obtaining and maintaining permits and licenses from various governmental authorities
- Environmental regulation and risks may adversely affect our business
- We may be exposed to liabilities under anti-bribery laws and a finding that we violated these laws could have a material adverse effect on our business
- If the United States imposes sanctions on Colombia, Ecuador or Canada in the future, our business may be adversely affected
- Regulations related to emissions and the impact of any changes in climate could adversely impact our business, including demand for our products, our financial condition and results of operations
- Reduction, elimination or expiration of government subsidies
- Carbon taxes and environmental compliance costs
- Risks Related to Ownership of our Common Stock
- Shares of our Common Stock are listed on the NYSE American, the Toronto Stock Exchange (“TSX”) and the London Stock Exchange (“LSE”) and investors seeking to take advantage of price differences between such markets may create unexpected volatility in market prices
- The market price of our Common Stock may be volatile
Legal proceedings
We have several lawsuits and claims pending. The outcome of the lawsuits and disputes cannot be predicted with certainty. We believe the resolution of these matters would not have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. We record costs as they are incurred or become probable and determinable.
