Santiago, Chile. November 22, 2017.- Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM) reported today earnings for the nine months ended September 30, 2017 of US$317.2 million (US$1.21 per ADR), an increase from US$197.4 million (US$0.75 per ADR) for the nine months ended September 30, 2016. Gross profit ⁽³⁾ reached US$546.4 million (34.5% of revenues) for the nine months ended September 30, 2017, higher than US$406.2 million (29.3% of revenues) recorded for the nine months ended September 30, 2016. Revenues totaled US$1,582.5 million for the nine months ended September 30, 2017, representing an increase of 14.2% compared to US$1,385.5 million reported for the nine months ended September 30, 2016.

The Company also announced earnings for the third quarter of 2017, reporting net income of US$112.9 million (US$0.43 per ADR) compared to US$55.8 million (US$0.21 per ADR) for the third quarter of 2016. Gross profit for the third quarter of 2017 reached US$188.5 million, higher than the US$145.7 million recorded for the third quarter of 2016. Revenues totaled US$558.7 million, an increase of approximately 10.8% compared to the third quarter of 2016, when revenues amounted to US$504.0 million.

SQM’s Chief Executive Officer, Patricio de Solminihac, stated: “The results we published for the first nine months of 2017 are a result of our strong position in all of the markets in which we are present. In the specialty plant nutrient business line strong sales volumes were due to strong demand growth along with decreased supply from our competition. Our operations team has been able to increase production in an efficient way, allowing us to increase our volumes while maintaining the supply and demand equilibrium in the market. Our sales volumes increased almost 9% during the first nine months of this year compared to the same period last year. In the potassium chloride market, our sales volumes surpassed 1.0 million MT during the first nine months of the year. Sales volumes for 2017 could surpass 1.3 million MT, a decrease compared to last year, but higher than our previous expectations.”

“In the lithium market, we continue to see strong demand growth and we saw prices continue to increase during the third quarter, surpassing US$13,000/ton, thus increasing another 8% compared to the second quarter. We believe this pricing trend should continue for the remainder of this year, and through the beginning of 2018. We continue to move forward with our new lithium projects. Our projects in Chile remain on time, and we expect to complete our lithium hydroxide and lithium carbonate expansions by the middle of 2018. In Argentina, we are investing in the first stage of the 25,000 MT expected to be online in 2019, and in Australia we finalized the documentation required to move forward with the joint venture with Kidman Resources.”

“In the iodine market, we have been working over the past several years to increase our sales volumes in line with our corporate strategy and operational plan. Market share has returned to levels greater than 30%, and we believe sales volumes will surpass 12,500 MT this year. Given these increase sales volumes, we are increasing our iodine production capacity to reach just over 14,000 MT as we want to ensure the supply is available to meet the demand of the future. With prices slightly higher than prices seen during the second quarter, we are optimistic about our future in the iodine market.”

Average prices during the third quarter reached US$20/kg, also increasing compared to the second quarter. This is in line with our expectations that prices reached a bottom during the first half of the year, and have been slowly increasing in recent months.

Demand in the iodine market is expected to grow about 3% during 2017, led by the x-ray contrast media and the pharmaceutical industry.

Gross profit for the Iodine and Derivatives segment accounted for approximately 7% of SQM’s consolidated gross profit for the nine months ended September 30, 2017.

Lithium and Derivatives

Revenues for lithium and derivatives totaled US$465.2 million during the nine months ended September 30, 2017, an increase of 37.7% compared to US$337.9 million recorded for the nine months ended September 30, 2016.

Revenues for lithium and derivatives during the third quarter of 2017 increased 15.6% compared to the third quarter of 2016. Total revenues amounted to US$167.8 million during the third quarter of 2017, compared to US$145.1 million in the third quarter of 2016.

Lithium demand growth continues to be strong and should surpass 14% this year. The average prices during the second half of 2017 should be higher than prices reported during the first half of the year.

Sales volumes were higher during the third quarter 2017 when compared to the previous quarters of 2017. We believe that sales volumes for the year will be similar to sales volumes seen during 2016.

Gross profit for the Lithium and Derivatives segment accounted for approximately 61% of SQM’s consolidated gross profit for the nine months ended September 30, 2017.

Potassium: Potassium Chloride & Potassium Sulfate (MOP & SOP)

Potassium chloride and potassium sulfate revenues for the nine months ended September 30, 2017 totaled US$301.0 million, similar to revenues reported during the nine months ended September 30, 2016, which totaled US$296.1 million.

Potassium chloride and potassium sulfate revenues remained flat in the third quarter of 2017, reaching US$113.0 million, compared to US$114.4 million for the third quarter of 2016.

Potassium Chloride and Potassium Sulfate Revenues	MUS$		113.0		114.4		-1.4	-1	%

In line with our previous statement, sales volumes decreased 3.7% in the nine months ended September 30, 2017 compared to the same period of 2016. Sales volumes seen in the third quarter 2017 decreased 12.4% compared to the third quarter 2016, as our continuous focus on lithium production results in reduced potassium chloride production in 2017.

We saw average prices in the potassium chloride and potassium sulfate business line show a growth of approximately 5.6% during the nine months ended September 30, 2017 when compared to the same period of 2016, reaching US$278/MT, similar to the average prices seen in the second quarter 2017.

Industrial Nitrates	Th. MT		19.2		16.3		3.0	18	%
Industrial Chemicals Revenues	MUS$		14.6		12.8		1.8	14	%

Revenues in the industrial chemicals business line increased as a result of higher sales volumes of solar salts ⁽⁵⁾ seen in the first quarter of 2017, which reached 45,000 MT. We expect solar salts sales volumes to be strong during the fourth quarter, surpassing 90,000 MT for the year. Average prices during the nine months ended September 30, 2017 decreased 2.9% compared to the nine months ended September 30, 2016.

Gross profit for the Industrial Chemicals segment accounted for approximately 5% of SQM’s consolidated gross profit for the nine months ended September 30, 2017.

The Chilean corporate tax rate was 25.5% during the 2017 period and 24.0% during the 2016 period.

Other

The EBITDA margin was approximately 41% for the nine months ended September 30, 2017. EBITDA margin for the nine months ended September 30, 2016 was approximately 38%. The EBITDA margin for the third quarter of 2017 was approximately 40%.

Notes:

Net income refers to the comprehensive income attributable to controlling interests.

EBITDA = gross profit - administrative expenses + depreciation and amortization. EBITDA margin = EBITDA/revenues.

Gross profit corresponds to consolidated revenues less total costs, including depreciation and amortization and excluding administrative expenses.

A significant portion of SQM’s costs of goods sold 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 report, 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.

Solar salts are a mix of 60% sodium nitrate and 40% potassium nitrate used for thermal energy storage.
