SQM - The Atacama Moat: World's Cheapest Lithium at the Bottom of the Cycle

SQM at a Glance

Sociedad Química y Minera de Chile S.A. is one of the world's largest producers of lithium, iodine, potassium nitrate, and specialty plant nutrients. Its flagship operation is the Salar de Atacama in northern Chile - the world's most productive lithium brine deposit, sitting at over 4,500 meters of altitude in the driest desert on earth. Unlike hard-rock lithium mining, which involves crushing spodumene ore and intensive chemical processing, SQM's brine operation uses the desert sun to evaporate naturally occurring lithium-rich saltwater into progressively concentrated pools - a vastly simpler and cheaper process. That geological accident is the source of SQM's structural cost advantage and its dominant position in the global supply chain.

SQM is not a pure-play lithium miner. Its iodine business - where Chile commands over 60% of global supply - has been delivering double-digit revenue growth in 2024, driven by demand from X-ray contrast media and LCD manufacturing. Its potassium nitrate segment for specialty agriculture is quietly resilient. These businesses provide a critical revenue floor when lithium prices are suppressed. In the second quarter of 2024, iodine revenues rose 22% year-over-year. That is not what a company in crisis looks like.

The Anatomy of the Collapse

To understand why SQM is interesting at $37, you need to understand why lithium did what it did - because the story of the 2022–2024 collapse is a textbook commodity cycle, not a structural technology problem.

It began with genuine, extraordinary demand. Electric vehicle sales accelerated sharply through 2021 and 2022, driven by government incentives, falling battery costs, and a surge in post-pandemic consumer spending. Lithium carbonate spot prices - sitting at roughly $7,000 per metric ton in early 2021 - hit over $80,000 per metric ton by November 2022. A tenfold increase in under two years.

At those prices, every lithium project that was economically marginal suddenly looked like a gold mine. Miners everywhere - in Chile, Argentina, Australia, China - rushed capital into capacity expansion. Meanwhile, EV growth rates, which had been extraordinary, began to normalize. Europe's EV sales slipped as government incentives were reduced in Germany and France. US growth slowed to a 7% quarterly rate in early 2024. China continued to grow strongly, but not fast enough to absorb the incoming supply wave.

The result was a spectacular oversupply. Prices that peaked above $80,000 declined to roughly $10,000 by mid-2024 - a 87% collapse. The narrative shifted from "lithium shortage crisis" to "lithium glut." Company revenues cratered. SQM's revenue fell 37% year-over-year in Q2 2024. Albemarle announced plans to shut half its Australian processing capacity. The pendulum had swung all the way to the other extreme.

This is the pattern. High prices attract excessive investment. Oversupply drives prices down. Low prices make new investment uneconomical and force existing capacity offline. Demand, still growing on the secular EV trend, eventually catches up to reduced supply. Prices recover. The cycle resets. It happened in oil in 2015–2016. It happened in iron ore. It will happen in lithium - the only question is the timing.

What makes SQM particularly compelling in this moment is precisely what makes commodity cycle investing difficult: you are buying maximum pessimism. The market is pricing SQM as though the oversupply is permanent, EV growth has peaked structurally, and the lithium cycle will not recover. Every one of those assumptions deserves serious scrutiny.

Profit at the Trough - Reading the Numbers

The most revealing thing about SQM right now is not that it is struggling. It is how little it is struggling at these conditions. The Q2 2024 profit flow diagram tells that story precisely.

SQM Q2 2024 Financial Flow as of June 28, 2024 - Revenue $1.38B → Net Income $213.6M (16.5% margin)

At first glance, the picture appears stressed: COGS consumes 70.3% of revenue ($908.7M), a significantly elevated ratio compared to the boom-era margins SQM enjoyed when lithium was at $50,000+ per metric ton. But read the numbers more carefully and a different story emerges.

Even after that elevated cost ratio - which directly reflects the compressed lithium price environment - SQM generates gross profit of $383.9M, an operating income of $309.8M (23.9% margin), and ultimately net income of $213.6M at a 16.5% net margin. This is not a company bleeding cash. This is a company running profitably at the bottom of its worst pricing cycle in a decade.

The tax line ($72.4M, 25.21% rate) is now normalized following the one-time $1.1 billion accounting adjustment in Q1 2024 related to the Chilean lithium mining tax from prior years. That Q1 distortion - which had no significant cash impact (most of it was already paid in previous years) - caused an alarming headline net loss of $870 million. That overhang is gone. Q2 demonstrates what SQM's ongoing earnings power looks like: approximately $200M+ per quarter in net income at trough lithium pricing.

Now ask yourself: if SQM earns $213M in a single quarter when lithium is at $10,000 per metric ton and COGS is running at 70% of revenue, what do those numbers look like when lithium recovers to $20,000? The Sankey diagram shows you the mechanical leverage: the cost base is largely fixed - brine evaporation is solar-powered and the Atacama doesn't charge rent. Revenue dollars above $10,000 per ton flow through at dramatically higher margins. A doubling of the lithium price could more than triple SQM's earnings per share.
