SQM is a Chilean mining and chemical company that sells lithium, iodine, specialty plant nutrients, and other industrial chemicals to customers around the world.
SQM is a Chilean company that digs minerals out of the ground and turns them into the ingredients other industries can't do without. Its biggest claim to fame is lithium — the light metal that goes into the batteries powering electric cars and energy storage. But that's only one piece. It also sells iodine, specialty plant nutrients for farmers, and industrial chemicals like potassium nitrate and solar salts. So it's less a single-product miner and more a diversified chemical maker with a handful of very different customers.
Here's why lithium matters so much. EVs and grid batteries need lithium, and SQM is one of the world's lowest-cost producers, pulling it from the brine beneath Chile's Atacama salt flat. That has made it a genuine heavyweight in the global lithium supply chain. Customers include battery makers and car companies, and it competes head-to-head with rivals like Albemarle. In iodine, SQM is the world's dominant producer, and iodine shows up in everything from X-ray contrast to pharmaceuticals and animal feed. The plant nutrients business sells to farmers — potassium nitrate and specialty fertilizers that help crops grow with less waste. The money story is heavily cyclical. When lithium prices soared in 2022–2023, SQM's profits ballooned; when they collapsed in 2024, profits fell hard. That whiplash is the heart of the investment case. A big structural wrinkle: SQM's access to the Atacama is linked to a contract with Chile's state copper company, Codelco, and a new partnership that hands Codelco majority control over the prized lithium operation starting in 2025. So SQM is trading some control for a longer lease on its crown jewel — smart politics, real dilution of ownership.
Beyond the brine, SQM has been expanding into new projects, including lithium in Australia and a growing stake in the battery-metal supply chain, to reduce its dependence on one salt flat and one price cycle. The company pays meaningful dividends when profits are fat and cuts them when they're thin. The honest summary: SQM is a well-run, low-cost resource company whose fortune rises and falls with lithium prices, Chile's shifting resource politics, and the world's appetite for batteries.
