SQM reported its 2Q2017 results. The company is a leading producer of lithium, iodine, potassium nitrate, and other specialty plant nutrients. In 1H2017, higher volumes of iodine and specialty plant nutrients outweighed lower prices, while lithium and potassium saw price increases. SQM has several expansion projects underway for lithium, iodine, and potassium production through 2018. It also has lithium projects in Argentina through a joint venture. SQM has a proven track record of generating cash and returning value to shareholders through dividends.
