Is SQM a Buy? What to Consider in 2026

Last updated June 2026

Short answer

There is no universal answer to whether SQM is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for Sociedad Quimica y Minera, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.

Sociedad Quimica y Minera de Chile, known as SQM, is a Chilean mining and chemicals company and one of the world's largest producers of lithium, a critical material for electric-vehicle and energy-storage batteries. SQM extracts lithium from brine in Chile's Atacama Desert, one of the lowest-cost and highest-quality lithium resources globally, under a concession with the Chilean state agency. Beyond lithium, SQM is a leading producer of specialty plant nutrients (potassium nitrate and specialty fertilizers), iodine (used in X-ray contrast media and other applications, where SQM is a global leader), and industrial chemicals. The company makes money selling these commodities and specialty products into global markets, with lithium being the most cyclical and most watched segment. SQM's fortunes are heavily tied to lithium prices, which swing sharply with EV demand and supply additions. Headquartered in Santiago, Chile, it trades in the US via American Depositary Receipts.

The case for Sociedad Quimica y Minera

1. Low-cost Atacama lithium resource.

SQM's brine operations in Chile's Atacama Desert are among the lowest-cost lithium sources in the world, giving it a structural cost advantage over higher-cost hard-rock (spodumene) producers. In a cyclical commodity, being low on the cost curve means SQM can stay profitable when prices fall and capture outsized margins when prices rise, supporting resilience through lithium cycles.

2. EV and energy-storage demand growth.

Long-term demand for lithium is tied to the global shift to electric vehicles and grid-scale battery storage. If EV adoption and renewable-energy storage continue expanding over the coming decade, structural lithium demand grows, and SQM is positioned as a major supplier with expansion capacity to meet it.

3. Diversification across iodine and specialty nutrients.

SQM is a global leader in iodine and a major producer of specialty plant nutrients and potassium nitrate. These businesses are less volatile than lithium and provide cash flow that cushions the swings in the lithium segment. Iodine in particular has steady demand from medical and industrial uses, adding stability to the overall portfolio.

4. Expansion and the Codelco partnership.

SQM has pursued capacity expansions and entered a public-private partnership framework with Codelco, Chile's state copper miner, to extend and develop Atacama lithium operations under the country's national lithium policy. Securing long-term access to the resource underpins SQM's ability to grow volumes over the coming years.

The risks to weigh

SQM's earnings are highly cyclical and dominated by volatile lithium prices, which have swung dramatically as supply additions outpaced demand at times, crushing margins. A large wave of new lithium supply globally can keep prices depressed for extended periods. As a Chilean producer, SQM faces sovereign and regulatory risk: the state controls the Atacama concession, royalties and tax terms can change, and national lithium policy reshapes who controls future production. Currency, political, and resource-nationalism risks in Chile are real. EV-demand growth could disappoint or shift toward chemistries that use less lithium. The stock tends to trade with commodity sentiment, making it volatile.

Valuation context (as of early 2026)

Revenue (TTM): ~$4 to 5 billion, highly variable with lithium prices
Lithium revenue share: the largest segment, swinging with commodity prices
Operating margin: wide swings; very high in lithium upcycles, compressed in downcycles
Iodine position: global market leader, a steadier earnings contributor
Dividend: variable, tied to a payout of fluctuating earnings
Cost position: among the lowest-cost lithium producers globally
P/E (TTM): highly variable across the commodity cycle

SQM is a commodity producer whose valuation and earnings track the lithium cycle. In upcycles margins and profits surge; in downcycles they compress sharply. The qualitative profile is a low-cost, diversified miner leveraged to long-term EV-battery demand but exposed to lithium-price volatility and Chilean policy. Earnings multiples are noisy and best read across a full cycle.

How to decide for yourself

Rather than asking whether SQM is a buy in the abstract, it tends to help to answer four questions:

Thesis: do you believe the case above, and is it still true today?
Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
Overlap: check whether you already hold SQM indirectly through an index or sector ETF before adding more.
