Ferroglobe Update on the U.S.
Antidumping and Countervailing Duty Cases

LONDON, Mar. 23, 2018 (GLOBE NEWSWIRE) -- Ferroglobe PLC (NASDAQ:GSM) ("Ferroglobe" or the "Company") has learned that the U.S. International Trade Commission ("ITC") determined today that the dumped and subsidized imports of silicon metal from Australia and Brazil, the dumped imports from Norway, and the subsidized imports from Kazakhstan are not causing material injury to the U.S. silicon metal industry.
On March 8, 2018, the U.S. Department of Commerce ("DOC") determined that the imports from these countries are being dumped at rates as high as 134.92% and are being subsidized at rates as high as 100%.
As a result of the negative ITC injury determinations, the DOC will not issue antidumping or countervailing duty orders and will terminate its investigations.
At this time, the ITC has not issued the Views of the Commission, which will explain the basis for these decisions.  The final determinations and Commission Views are scheduled to be issued by April 10, 2018.
Ferroglobe disagrees with this outcome.  The company will review the ITC determinations with its counsel and will decide what further steps to take with respect to those determinations.

The ITC's press release regarding the final determinations will be published at:

These investigations were initiated in response to a petition filed by Globe Specialty Metals, Inc., a subsidiary of Ferroglobe, alleging that the imports from Australia, Brazil, and Norway were being dumped (sold at unfairly low import prices) and that the imports from Australia, Brazil, and Kazakhstan were being unfairly subsidized.
