SCCO · CIK 1001838
What Southern Copper Corporation told the SEC could break it.
Southern Copper is overwhelmingly a bet on one metal: copper generated about 75.9% of its revenue over the past three years (the rest molybdenum, silver and zinc), so its results swing with copper prices — which are heavily driven by demand from China, the world's largest refined-copper consumer. Trade policy has become a sharp, specific risk on top of that: the U.S. imposed a 50% tariff on semi-finished copper products and copper-intensive derivatives effective August 2025, and a subsequent 15% global tariff and a February 2026 Supreme Court limit on emergency tariff powers have added market volatility for its products and stock. Its operations are also geographically concentrated in Peru and Mexico, with roughly $10.2 billion of planned Mexican investment dependent on ongoing talks with that government — concentrating its permitting and political risk in two countries.

In its own words
What could break it.
Commodity & input dependence
- copper (~76% of revenue), with prices driven by China demand; moly/silver/zinc by-productshigh
Southern Copper derived ~75.9% of revenue from copper over the last three years (plus molybdenum, silver and zinc), so results are highly sensitive to copper prices — which are heavily influenced by demand from China, the world's largest refined-copper consumer.
“Over the last three years, approximately 75.9% of our revenues were generated from the sale of copper; 10.9% from molybdenum; 5.7% from silver; and 3.6% from zinc.”
Regulatory & policy
- US 50% tariff on semi-finished copper products (Aug 2025) + 15% global tariffhigh
On July 30, 2025 the US announced a 50% tariff on semi-finished copper products and copper-intensive derivatives (effective Aug 1, 2025); a subsequent declared 15% global tariff and the Feb 20, 2026 Supreme Court limit on emergency tariff powers have produced market volatility for Southern Copper's products and stock.
“On July 30, 2025, the U.S. announced a 50% tariff on semi-finished copper products and copper-intensive derivative products, which became effective on August 1, 2025. Additionally, reciprocal tariffs with China have been suspended until November 10, 2026.”

Geographic concentration
- mining operations concentrated in Peru and Mexicomedium
Southern Copper's mines, smelters and refineries are concentrated in Peru and Mexico, with ~$10.2 billion of planned Mexican investments dependent on ongoing discussions with the current administration — concentrating operational, permitting and political risk in those two countries.
“We are having ongoing discussions with the current administration to continue rolling out SCC's Mexican investments for $10.2 billion.”
