SunCoke Energy, Inc. (NYSE: SXC) today reported preliminary third quarter 2014 domestic coke production of 1,090 thousand tons, up 31 thousand tons versus the production of 1,059 thousand tons in second quarter 2014. On a year-over-year basis, production was up an estimated 9 thousand tons versus third quarter 2013 primarily due to higher production at our Granite City facility, reflecting better coal-to-coke yields. Indiana Harbor saw sequential quarter and year-over-year improvement, achieving production within our targeted range in third quarter 2014.

Domestic capacity utilization in third quarter 2014 is estimated to be 102 percent as compared to 101 percent in the same prior year period.
