Santiago, Chile. August 23, 2017.- Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) reported earnings today for the six months ended June 30, 2017 of US$204.4 million (US$0.78 per ADR), an increase from US$141.6 million (US$0.54 per ADR), representing a 44.3% increase compared to the earnings reported for the six months ended June 30, 2016. Gross profit ⁽²⁾ reached US$357.8 million (35.0% of revenues) for the six months ended June 30, 2017, higher than US$260.5 million (29.6% of revenues) recorded for the six months ended June 30, 2016. Revenues totaled US$1,023.9 million for the six months ended June 30, 2017, representing an increase of 16.2% compared to US$881.5 million reported for the six months ended June 30, 2016.

The Company also announced earnings for the second quarter of 2017, reporting net income of US$101.2 million (US$0.38 per ADR) compared to US$83.1 million (US$0.32 per ADR) for the second quarter 2016. Gross profit for the second quarter 2017 reached US$179.9 million; higher than the US$146.9 million recorded for the second quarter 2016. Revenues totaled US$505.7 million, an increase of approximately 3.3% compared to the second quarter 2016, when revenues amounted to US$489.6 million.

SQM’s Chief Executive Officer, Patricio de Solminihac, stated, “We are pleased with the results we published today. The EBITDA for this first half of the year was US$433 million. Sales volumes in the specialty plant nutrition business line were the strongest reported in recent history. As anticipated, the sales volumes in the potassium chloride business line were down compared to the second quarter last year; we are still expecting that sales volumes in this business line will be between 1.2 and 1.3 million MT this year as we maximize lithium production. Also as anticipated, potassium chloride prices have stabilized at higher levels than last year.”

“In the lithium market, we continue to see strong demand growth. We expect the average price in the second half to be higher than the average price seen during the first half of this year. We continue to move forward with our new projects; in Chile, the lithium hydroxide expansion and the lithium carbonate expansion are expected to be completed by the middle of 2018. In Argentina, we are working on the hydrogeological model with the corresponding drilling, a key component of the final development stage. Finally, during July, we announced a 50/50 joint venture with Kidman Resources to develop a 40,000 MT lithium project in western Australia, the high-quality Mount Holland project. These initiatives are in line with our strategic plan to continue developing lithium projects where our competitive advantages and expertise add significant value to a growing and attractive market.”

“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. This year our market share should return to levels seen before the price boom period. During the first half of 2017, we saw sales volumes reach the highest levels reported during any six-month period. As anticipated, these higher sales volumes have come with lower prices, but given our current cost position, margins are healthy. Because of the higher sales volumes we have seen in recent quarters, and expectations that this trend will continue in the future, we are adding new iodine capacity in Nueva Victoria. We expect that this expansion will bring our total capacity to approximately 14,000 MT, and it is expected to be operational in mid-2018.”

Segment Analysis

Specialty Plant Nutrition (SPN)

Revenues from our Specialty Plant Nutrition business line for the six months ended June 30, 2017 totaled US$325.7 million, slightly lower than the US$332.2 million reported for the six months ended June 30, 2016.

Second quarter 2017 revenues reached US$189.5 million, similar to the US$191.1 million reported in the second quarter 2016.

*Includes trading of other specialty fertilizers.

We saw an increase in the sales volumes in this market during the first half of 2017, and we believe that sales volumes in 2017 will surpass sales volumes in 2016 resulting from decreased supply from the competition and increased demand, specifically in the water-soluble market. We have the capacity to supply market growth, and will continue to ensure market needs are met as we increase our nitrates capacity; we remain confident in the future of the potassium nitrate and specialty fertilizer markets.

SPN gross profit ⁽³⁾ accounted for approximately 18% of SQM’s consolidated gross margin for the six months ended June 30, 2017.

Iodine and Derivatives

Revenues from sales of iodine and derivatives during the six months ended June 30, 2017 totaled US$129.1 million, an increase of 8.8% compared to US$118.6 million reported for the six months ended June 30, 2016.

Iodine and derivatives revenues for the second quarter 2017 amounted to US$62.8 million, an increase of 4.2% compared to US$60.3 million recorded during the second quarter 2016.

Iodine and Derivative Sales Volumes and Revenues:

		6M2017		6M2016		2017 /2016
Iodine and Derivatives	Th. MT		6.6		4.9		1.7	34	%
Iodine and Derivatives Revenues	MUS$		129.1		118.6		10.5	9	%

		2Q2017		2Q2016		2017/2016
Iodine and Derivatives	Th. MT		3.2		2.6		0.7	25	%
Iodine and Derivatives Revenues	MUS$		62.8		60.3		2.5	4	%

Iodine revenues during the second quarter were higher to revenue seen during the same period last year. Average prices during the second quarter reached US$20/kg. Our competitive cost position is s allowing us to see healthy margins in this business.

As a result of our strategy in the iodine and derivatives business line, we have been steadily increasing our sales volumes over the past several years. Sales volumes between 2014 and 2016 increased over 16%, thus increasing our market share during that period. During the first half of 2017, we saw sales volumes reach 6,600 MT, the highest levels reported for any six-month period. We believe that 2017 sales volumes could increase over 15% compared to last year, surpassing 12,000 MT.

Our production comes mainly from our facility in Nueva Victoria, the largest and most efficient plant in the world. This year, the difference between our projected sales volumes and our production capacity will come from our strategic inventories. Over the past several quarters we have been consuming part of these inventories, and we are now working on debottlenecking and expanding our iodine production capacity to reach just over 14,000 MT by mid-2018. We believe that the total investment will be approximately US$30 million. We have also been working on the exploration, engineering and permitting of a new greenfield project in Chile to ensure that future market demand is met. Construction will begin depending on market conditions.

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

Lithium and Derivatives

Revenues from lithium and derivatives business line totaled US$297.4 million during the six months ended June 30, 2017, an increase of 54.3% compared to US$192.8 million recorded for the six months ended June 30, 2016.

Revenues for lithium and derivatives during the second quarter 2017 increased 32.7% compared to the second quarter 2016. Total revenues amounted to US$151.1 million during the second quarter of 2017, compared to US$113.9 million in the second quarter of 2016.

Lithium and Derivatives Sales Volumes and Revenues:

		6M2017		6M2016		2017/2016
Lithium and Derivatives	Th. MT		23.8		23.0		0.8	3	%
Lithium and Derivatives Revenues	MUS$		297.4		192.8		104.7	54	%

		2Q2017		2Q2016		2017/2016
Lithium and Derivatives	Th. MT		11.5		12.1		-0.6	-5	%
Lithium and Derivatives Revenues	MUS$		151.1		113.9		37.2	33	%

Lithium demand remains strong, and we still believe demand growth could be around 14% this year. We believe that market prices will trend up during the remainder of the 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 slightly lower during the second quarter 2017 when compared to the first quarter 2017, but we still believe that sales volumes for the year will remain similar to sales volumes seen during 2016.

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

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

Potassium chloride and potassium sulfate revenues for the six months ended June 30, 2017 totaled US$188.0 million, a 3.5% increase compared to the six months ended June 30, 2016, when revenues amounted to US$181.6 million.

Potassium chloride and potassium sulfate revenues decreased 18.9% in the second quarter of 2017, reaching US$78.9 million, compared to US$97.3 million for the second quarter of 2016.

Potassium Chloride & Potassium Sulfate Sales Volumes and Revenues:

		6M2017		6M2016		2017/2016
Potassium Chloride and Potassium Sulfate	Th. MT		676.3		660.3		15.9	2	%
Potassium Chloride and Potassium Sulfate Revenues	MUS$		188.0		181.6		6.3	3	%

		2Q2017		2Q2016		2017/2016
Potassium Chloride and Potassium Sulfate	Th. MT		281.1		375.1		-94.0	-25	%
Potassium Chloride and Potassium Sulfate Revenues	MUS$		78.9		97.3		-18.4	-19	%

We saw a 2.4% increase in sales volumes in the six months ended June 30, 2017 compared to the same period of 2016. These increased sales volumes are attributable to the higher sales volumes seen in the first quarter of 2017 when compared to the same period in 2016. However, sales volumes seen in the second quarter 2017 decreased 25.1% compared to the second quarter 2016, in line with what we have reported previously about our focus on lithium production and a decrease in potassium chloride production in 2017.

We saw average prices in the potassium chloride and potassium sulfate business line show a slight growth of approximately 1.1% during the six months ended June 30, 2017 when compared to the same period in 2016, reaching US$278/MT. The average price recovery trend in 2017 resulted in average prices increasing approximately 1.8% in the second quarter of 2017 when compared to first quarter of 2017.

As previously reported, our focus on lithium production will lead to a decrease in potassium chloride production in 2017, resulting in lower potassium sales volumes of approximately 20%.

Gross profit for potassium chloride and potassium sulfate accounted for approximately 8% of SQM’s consolidated gross margin for the six months ended June 30, 2017.

Industrial Chemicals

Industrial chemicals revenues for the six months ended June 30, 2017 reached US$66.4 million, 117.5% higher than US$30.5 million recorded for the six months ended June 30, 2016.

Revenues for the second quarter of 2017 totaled US$14.7 million, an increase of 8.3% compared to the revenue figures for second quarter of 2016 of US$13.6 million.

Industrial Chemicals Sales Volumes and Revenues:

		6M2017		6M2016		2017/2016
Industrial Nitrates	Th. MT		84,0		37,3		46,7	125	%
Industrial Chemicals Revenues	MUS$		66,4		30,5		35,9	118	%

Industrial Nitrates	Th. MT		19,3		16,9		2,4	14	%
Industrial Chemicals Revenues	MUS$		14,7		13,6		1,1	8	%

Revenues in the industrial chemicals business line increased as a result of higher sales volumes, led by solar salts ⁽⁴⁾ sales, which reached approximately 45,000 MT in the first quarter of 2017. Average prices during the six months ended June 30, 2017 slightly decreased compared to the six months ended June 30, 2016.

Gross profit for the Industrial Chemicals segment accounted for approximately 6% of SQM’s consolidated gross margin for the six months ended June 30, 2017.

Notes:

	1)	Net income refers to the comprehensive income attributable to controlling interests.
	2)	Gross profit corresponds to consolidated revenues less total costs, including depreciation and amortization and excluding administrative expenses.
	3)	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.
	4)	Solar salts are a mix of 60% sodium nitrate and 40% potassium nitrate used for thermal energy storage.
	5)	EBITDA = gross profit - administrative expenses + depreciation and amortization. EBITDA margin = EBITDA/revenues.
