[6-K] CHEMICAL & MINING CO OF CHILE INC Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Sociedad Química y Minera de Chile (SQM) reported net income of US$404.4 million (US$1.42 per share) for the nine months ended September 30, 2025, reversing a net loss of US$(524.5) million (US$(1.84) per share) a year earlier. Revenues for the period were US$3,252.4 million, down 5.9% year-on-year, while gross profit declined to US$904.1 million, or 27.8% of revenues.

In the third quarter, net income rose 35.8% to US$178.4 million, with revenues up 8.9% to US$1,173.0 million and gross profit up 23.1% to US$345.8 million. Lithium and derivatives drove results, with Q3 segment revenues up 21.4% to US$603.7 million on record sales volumes and a modest price recovery from Salar de Atacama operations.

Iodine and derivatives posted higher revenues supported by strong prices, and specialty plant nutrition delivered modest volume and revenue growth. Potassium revenues fell sharply as SQM deliberately reduced potash output to favor lithium in the Salar de Atacama. The company updated its 2025–2027 capex plan to US$2.7 billion and highlighted Chinese antitrust approval for its Atacama partnership with Codelco.

Insights

Equity analyst – lithium and chemicals

SQM shows strong Q3 rebound, lithium volume records, and strategic capex reset.

SQM has shifted from a nine‑month net loss of US$(524.5) million in 2024 to net income of US$404.4 million in 2025, despite revenues slipping 5.9% to US$3,252.4 million. Q3 performance was notably stronger: revenues rose 8.9% to US$1,173.0 million, net income increased 35.8% to US$178.4 million, and adjusted EBITDA climbed to US$404.1 million with a 34.5% margin.

Lithium is the main driver. Q3 lithium and derivatives revenues rose 21.4% to US$603.7 million, with total volumes up 43% year-on-year. Management reports record lithium sales volumes, a realized average price from Salar de Atacama near US$8.8 per kilogram, and a quarter‑over‑quarter price uptick after two years of declines. Australian spodumene volumes and initial lithium hydroxide output add a second growth leg.

Strategically, SQM updated its 2025–2027 capex plan to US$2.7 billion, spread evenly, including seawater pipeline completion, Chilean lithium expansions, and Mt. Holland and Andover investments subject to final decisions. Potassium revenues dropped 43% for nine months as the company reallocates brine capacity to lithium, which aligns operations with higher‑value products. Chinese SAMR approval for the Atacama partnership with Codelco provides an important regulatory step for long‑term lithium development.

Santiago, Chile - November 18, 2025 - Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) reported today net income for the nine months ended September 30, 2025, of US$404.4 million or US$1.42 per share, compared to a loss of US$(524.5) million or US$(1.84) per share reported for the same period last year.

Gross profit(1) reached US$904.1 million (27.8% of revenues) for the nine months ended September 30, 2025, lower than US$1,033.3 million (29.9% of revenues) recorded for the nine months ended September 30, 2024. Revenues totaled US$3,252.4 million for the nine months ended September 30, 2025, representing a decrease of 5.9% compared to US$3,455.0 million reported for the nine months ended September 30, 2024.

The Company also announced net income for the third quarter of 2025 of US$178.4 million or US$0.62 per share, an increase of 35.8% compared to US$131.4 million or US$0.46 per share for the third quarter of 2024. Gross profit for the third quarter of 2025 reached US$345.8 million, 23.1% higher than the US$280.8 million reported for the third quarter of 2024. Revenues totaled US$1,173.0 million for the third quarter of 2025, an increase of 8.9% compared to US$1,076.9 million for the third quarter of 2024.

SQM’s Chief Executive Officer, Ricardo Ramos, stated, “As anticipated, during the third quarter we observed an improved pricing environment in lithium compared to the previous quarter. Although the lithium market has shown to be volatile, we are optimistic, as our realized average prices increased for the first time after two years1, and we expect this upward trend to continue through the fourth quarter supported by strong demand for lithium, not only from electric vehicles (EV) but also from energy storage systems (ESS).”

He added: “During the quarter, we achieved the highest lithium sales volumes in SQM’s history, while maintaining low costs and strong operating efficiency at our Atacama operations. At the same time, the ramp-up of our Australian operations is progressing smoothly and according to plan. As expected, sales of spodumene produced in Australia increased significantly, and we also began lithium hydroxide production in the country. We reached record sales volumes of spodumene concentrate, marking a milestone in the project’s short history.”

Mr. Ramos continued: “Positive results were not limited to lithium. Our Iodine and Plant Nutrition division also delivered solid performance. In iodine, we continue to observe prices at a high level due to current balance between supply and demand. In addition, construction of our seawater pipeline is now more than 80% complete, a key milestone that will enable us to bring additional product to the market if required earlier than expected.”

He added: “In the fertilizer business, we observed healthy demand and firmer prices across most of our key markets.”

SQM S.A. 3Q2025 Earnings release 1

The CEO closed by saying: “Finally, as announced last week by SQM and Codelco, we have obtained authorization from the Chinese antitrust authority (SAMR) for our partnership to jointly develop the Atacama salt flat. This is a major milestone, and we look forward to advancing this joint venture, which will allow Chile to play a leading role in the development of new clean technologies.”

Capex Update

We have reviewed our capital expenditure program for the 2025–2027 period and now estimate total capex at US$2.7 billion. Some investment decisions have been delayed, but we have been able to do so without impacting on our ability to reach the production and sales objectives set for each of our divisions. This capital expenditure plan is expected to be evenly distributed over the three years, with approximately 25% allocated to maintenance.

This capex program considers the investments needed to finalize the seawater pipeline, the Maria Elena iodine production site, along with the expansion of our lithium carbonate and lithium hydroxide capacity in Chile. It is also included the investments needed for the expansion of the Mt. Holland project, along with the initial investments to develop the Andover project, both in Australia. Disbursements related to the latter two projects remain contingent upon reaching final investment decisions with our partners.

SQM S.A. 3Q2025 Earnings release 2

*Reflects SQM’s attributable portion only

During the third quarter, we saw the highest lithium sales volume in our history, mainly driven by a stronger demand growth than previously anticipated. The stronger-than-expected lithium demand growth came not only from the electric vehicle industry, but also from the battery energy storage systems, that already represents more than 20% of the global lithium demand. In addition, we observed lower inventory levels across the entire supply chain, which, together with some supply disruptions seen in recent months, contributed to a shift in the overall price trend.

Our realized average price from the Salar de Atacama operations was close to US$8.8 per kilogram , representing a 3.5% increase compared to the previous quarter. Although the increase was modest, it signals a turning point in pricing in a volatile market.

In Australia, we posted record sales volumes and we expect similar commercial activity in the fourth quarter mainly related to spodumene concentrate. The Kwinana refinery continues its ramp-up, which we expect to be close to nameplate capacity by the end of 2026. Same as with lithium carbonate prices, we have also seen a turning point, that makes us believe that prices in the fourth quarter should be higher than prices reported in the third quarter.

Gross profit(1) for the Lithium and Derivatives segment accounted for 38% of SQM’s consolidated gross profit for the nine months ended September 30, 2025.

Specialty Plant Nutrition (SPN)

Revenues from our Specialty Plant Nutrition business line for the nine months ended September 30, 2025 totaled US$732.4 million, an increase when compared to US$717.3 million reported for the nine months ended September 30, 2024.

*Includes trading of other specialty fertilizers.

During the third quarter of 2025, both sales volumes and revenues slightly increased compared to the same period last year, reflecting healthy demand across our main markets, particularly in the Americas and Europe.

In our SPN business line, we continue to advance our strategy of offering tailor-made solutions to our clients. This has led to a shift in our product mix, with a greater emphasis on specialty blends and high-value plant nutrients, allowing us to both diversify our portfolio and strategically allocate products to the most attractive markets.

Gross profit(1) for SPN segment accounted for 12% of SQM’s consolidated gross profit for the nine months ended September 30, 2025.

Iodine and Derivatives

Revenues from sales of iodine and derivatives during the nine months of 2025 totaled US$770.8 million, an increase of 3.8% compared to US$742.8 million reported for the nine months of 2024.

Revenues from sales of iodine and derivatives during the third quarter of 2025, totaled US$244.6 million, an increase of 4.7% compared to US$233.5 million reported for the third quarter of 2024.

Iodine and Derivative Sales Volumes and Revenues:

Iodine and Derivatives Revenues						MUS$						244.6						233.5						11.1						5%

In the third quarter, revenues from our iodine and derivatives business increased by 5% year-on-year, with iodine prices averaging US$72.7 per kilogram (excluding derivatives), remaining relatively flat quarter-on-quarter and up nearly 6% year-on-year.

As mentioned in our previous earnings report, we expect global iodine market demand to remain broadly stable in 2025 compared to 2024 due to customer destocking, and to grow by approximately 3% in 2026 versus 2025. The market continues to be driven primarily by the x-ray contrast media segment, which we estimate is expanding at a steady rate of around 6% per year.

We continue to invest in expanding our production capacity to be ready to meet future demand. Construction of our seawater pipeline is well advanced, and we expect it to be operational during the second or third quarter of 2026, enabling us to unlock additional production capacity.

Gross profit(1) for the Iodine and Derivatives segment accounted for 46% of SQM’s consolidated gross profit for the nine months ended September 30, 2025.

Potassium

Potassium revenues for the nine months ended September 30, 2025, totaled US$116.7 million, lower than revenues reported during the nine months ended September 30, 2024, which totaled US$204.9 million, representing a 43.0% decrease.

Adjusted EBITDA for the third quarter of 2025 was US$404.1 million (Adjusted EBITDA margin of 34.5%), compared to US$327.3 million (Adjusted EBITDA margin of 30.4%) for the third quarter of 2024.

Notes:

(1) A significant portion of SQM’s cost of sales are costs related to common productive processes (mining, crushing, leaching, etc.) which are distributed among the different final products. To estimate gross profit by business line in both periods covered by this release, the Company employed similar criteria on the allocation of common costs to the different business areas. This gross profit distribution should be used only as a general and approximated reference of the margins by business line.

(2) Adjusted EBITDA = EBITDA – Other income – Other gains (losses) - Share of Profit of associates and joint ventures accounted for using the equity method + Other expenses by function + Net impairment gains on reversal (losses) of financial assets – Finance income – Currency differences. EBITDA = Profit for the Period + Depreciation and Amortization Expenses + Finance Costs + Income Tax. Adjusted EBITDA margin = Adjusted EBITDA/revenues. We have included adjusted EBITDA to provide investors with a supplemental measure of our operating performance. We believe adjusted EBITDA is important supplemental measure of operating performance because it eliminates items that have less bearing on our operating performance and thus highlights trends in our core business that may not otherwise be apparent when relying solely on IFRS financial measures. Adjusted EBITDA has important limitations as analytical tool. For example, adjusted EBITDA does not reflect (a) our cash expenditures, or future requirements for capital expenditures or contractual commitments; (b) changes in, or cash requirements for, our working capital needs; (c) the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt; and (d) tax payments. Although we consider the items excluded in the calculation of non-IFRS measures to be less relevant to evaluate our performance, some of these items may continue to take place and accordingly may reduce the cash available to us.

We believe that the presentation of the non-IFRS financial measures described above is appropriate. However, these non-IFRS measures have important limitations as analytical tools, and you should not consider them in isolation, or as substitutes for analysis of our results as reported under IFRS. Because of these limitations, we primarily rely on our results as reported in accordance with IFRS and use EBITDA and adjusted EBITDA only supplementally.

SQM’s updated 2025–2027 capex plan is US$2.7 billion, expected to be evenly distributed over three years, with around 25% for maintenance. It includes completing the seawater pipeline and Maria Elena iodine site, expanding lithium carbonate and lithium hydroxide capacity in Chile, and funding the Mt. Holland expansion and initial Andover project investments in Australia, with the latter two subject to final investment decisions with partners.
