FERROGLOBE APPOINTS PHILLIP MURNANE CHIEF FINANCIAL OFFICER

LONDON, June 25, 2018 (GLOBE NEWSWIRE) – Ferroglobe PLC (NASDAQ: GSM) ("Ferroglobe" or the "Company"), the world's leading producer of silicon metal, and a leading silicon- and manganese-based specialty alloys producer, is pleased to announce that it has appointed Phillip Murnane Chief Financial Officer ("CFO"), effective July 9, 2018.

Mr. Murnane succeeds Joe Ragan, who has chosen to step down from his position to pursue other personal and professional interests with a view to being closer to his family in the United States. Mr. Ragan has agreed with the Company that he will remain engaged and working with management until the end of 2018 to provide for a seamless transition in leadership and responsibilities.

Javier Lopez Madrid, Ferroglobe's Executive Chairman, commented, "Phil brings a unique combination of financial expertise and profound operational leadership to Ferroglobe, and we are thrilled to have him join our senior management team. His finance and risk management acumen, particularly in metals and mining, combined with his proven track record of delivering corporate initiatives on a global scale, will be critical in supporting our growth and increasing shareholder value over the long-term."

Pedro Larrea, Ferroglobe's Chief Executive Officer, said, "Joe has been an integral part of Ferroglobe for the past five years, leading its successful integration, strengthening the balance sheet, and positioning the Company with a healthy financial structure for continued growth. We thank him for his dedication and support, and wish him the very best in his future endeavors."

Mr. Ragan added, "I am very proud of what we have accomplished during my time at Ferroglobe – building the Company into a world class speciality metal business. While choosing to leave was a difficult decision, I depart confidently knowing that Phil is the ideal individual to take on the role of CFO and help the Company achieve its long-term financial and strategic goals."

Mr. Murnane brings to Ferroglobe over 15 years of experience in senior financial and operational leadership positions across the commodities sector, including management roles within the Noble Group, Glencore and Centrica. Most recently, he was at Noble Group Limited, where latterly he held a dual role as Chief Operating Officer of the Americas and EMEA and of Global Energy. Prior to Noble Group, he served as Finance Director at Glencore International. Previously, he worked with Centrica plc in their upstream assets and midstream trading business. Mr. Murnane began his career working in the Enterprise Risk Services group at Deloitte. He holds a Bachelor of Commerce and a Bachelor of Economics from Australian National University and is a Member of the Institute of Chartered Accountants of Australia.
