Strong cash flow generation continues to support liquidity

Working capital decreased by $11.6 million¹ during the quarter, primarily a result of the increased securitization of receivables. Year-to-date the company has increased total working capital by $8.6 million¹due to the recovery cycle. Ferroglobe continued to generate positive cash flows. During the third quarter, the company generated operating cash flows of $67.4 million¹, free cash flow of $52.7 million¹, with total free cash flow of $58.5 million¹ year to date.

Ferroglobe's net debt was $394.3 million¹ at the end of Q3 2017, down compared to $434.6 million at the end of Q2 2017.

¹As of September 30, 2017, the balance sheet includes the securitized accounts receivables under the Company's new global accounts receivables securitization program which began in July 2017. As such, $120.1M is included in debt and accounts receivables in the balance sheet as of September 30, 2017, which reflects the receivables sold into the program. However, the impact of the securitization is included in the calculation of certain key metrics, such as net debt, working capital, cash flows from operations and free cash flow in order make such metrics comparable.

Recent developments

The trade cases in the United States and the favorable demand environment have allowed Ferroglobe to return to close to full capacity utilization. The Selma facility (Alabama, US) has restarted operations, and the remainder of Ferroglobe's European and North American plants are running at full capacity. Facilities in Argentina and South Africa are at 50% and 65% utilization, respectively, as a result of unfavorable local conditions, but are planning to restart full operations in the near future. Ferroglobe's plant in Venezuela has halted operations since May, as the company awaits further developments in the country.

In the ongoing trade cases that Ferroglobe filed in the U.S., the Department of Commerce ("DOC") issued preliminary determinations on August 7, 2017 imposing countervailing duties on silicon metal imports from Australia, Brazil and Kazakhstan. The duties imposed ranged from 3.69% to 120%. The DOC made preliminary determinations on October 5, 2017 in the antidumping cases against Australia, Brazil and Norway. The antidumping duties imposed ranged from 3.74% to 134.92%. Now more than 63% of silicon metal imports into the U.S. are subject to cash deposit requirements.

On November 2, 2017, the Canadian International Trade Tribunal ("CITT") determined that dumped silicon metal imports from Laos and Thailand, subsidized imports from Norway, and dumped and subsidized imports from Brazil, Kazakhstan and Malaysia had not caused injury and were not threatening to cause injury to the sole Canadian producer, Quebec Silicon Limited Partnership and QSIP Canada ULC ("Quebec Silicon").

The CITT issued its reasons for decision on November 17, 2017. We believe the CITT made several critical errors regarding, among others, the impact and relevance of global price declines on Canadian market pricing and the basis on which silicon metal is negotiated and sold to customers in Canada. Ferroglobe intends to appeal the CITT's decision to the Federal Court of Appeal.

We note this decision has no relevance for or impact on the ongoing antidumping and countervailing duty cases in the United States against silicon metal imports from Australia, Brazil, Kazakhstan and Norway because these are different proceedings in different jurisdictions, based on different facts and different legal standards.

On November 21, Ferroglobe announced that it has entered into an agreement for the acquisition of a 100% interest in Glencore's manganese alloys plants in Dunkirk (France) and Mo I Rana (Norway). The parties expect the transaction to close in the first quarter of 2018, subject to obtaining certain regulatory approvals in France, Germany and Poland and other customary conditions.

Ferroglobe will review the results for the third quarter of 2017 during a conference call at 9:00 a.m. Eastern Time on Tuesday, November 28, 2017.

Forward-Looking Statements

This release contains "forward-looking statements" within the meaning of U.S. securities laws. Forward-looking statements are not historical facts but are based on certain assumptions of management and describe the Company's future plans, strategies and expectations. Forward-looking statements often use forward-looking terminology, including words such as "anticipate", "believe", "could", "estimate", "expect", "forecast", "guidance", "intends", "likely", "may", "plan", "potential", "predicts", "seek", "will" and words of similar meaning or the negative thereof.

Forward-looking statements contained in this press release are based on information presently available to the Company and assumptions that we believe to be reasonable, but are inherently uncertain. As a result, Ferroglobe's actual results, performance or achievements may differ materially from those expressed or implied by these forward-looking statements, which are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors that are, in some cases, beyond the Company's control.

Forward-looking financial information and other metrics presented herein represent the Company's goals and are not intended as guidance or projections for the periods presented herein or any future periods.

Non-IFRS Measures

EBITDA, adjusted EBITDA, adjusted diluted profit (loss) per ordinary share and adjusted profit (loss) attributable to the parent are, we believe, pertinent non-IFRS financial metrics that Ferroglobe utilizes to measure its success. Ferroglobe has included these financial metrics to provide supplemental measures of its performance. The Company believes these metrics are important because they eliminate items that have less bearing on the Company's current and future operating performance and highlight trends in its core business that may not otherwise be apparent when relying solely on IFRS financial measures.

Forward-looking statements can generally be identified by the use of forward-looking terminology, including, but not limited to, "may," “could,” “seek,” “guidance,” “predict,” “potential,” “likely,” "believe," "will," "expect," "anticipate," "estimate," "plan," "intend," "forecast," or variations of these terms and similar expressions, or the negative of these terms or similar expressions. Forward-looking statements contained in this presentation are based on information presently available to us and assumptions that we believe to be reasonable, but are inherently uncertain. As a result, our actual results, performance or achievements may differ materially from those expressed or implied by these forward-looking statements, which are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors that are, in some cases, beyond our control. You are cautioned that all such statements involve risks and uncertainties, including without limitation, risks that the businesses of Globe Specialty Metals Inc. and Grupo FerroAtlántica (together, “we,” “us,” “Ferroglobe,” the “Company”) will not be integrated successfully or that we will not realize estimated cost savings, value of certain tax assets, synergies and growth, or that such benefits may take longer to realize than expected. Important factors that may cause actual results to differ include, but are limited to: (i) risks relating to unanticipated costs of integration, including operating costs, customer loss and business disruption being greater than expected; (ii) our organizational and governance structure; (iii) the ability to hire and retain key personnel; (iv) regional, national or global political, economic, business, competitive, market and regulatory conditions including, among others, changes in metals prices; (v) increases in the cost of raw materials or energy; (vi) competition in the metals and foundry industries; (vii) environmental and regulatory risks; (viii) ability to identify liabilities associated with acquired properties prior to their acquisition; (ix) ability to manage price and operational risks including industrial accidents and natural disasters; (x) ability to manage foreign operations; (xi) changes in technology; (xii) ability to acquire or renew permits and approvals; (xiii) changes in legislation or governmental regulations affecting Ferroglobe; (xiv) conditions in the credit markets; (xv) risks associated with assumptions made in connection with critical accounting estimates and legal proceedings; (xvi) Ferroglobe's international operations, which are subject to the risks of currency fluctuations and foreign exchange controls; and (xvii) the potential of international unrest, economic downturn or effects of currencies, tax assessments, tax adjustments, anticipated tax rates, raw material costs or availability or other regulatory compliance costs. The foregoing list is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that affect our business, including those described in the “Risk Factors” section of our Registration Statement on Form F-1, Annual Reports on Form 20-F, Current Reports on Form 6-K and other documents we file from time to time with the United States Securities and Exchange Commission. We do not give any assurance (1) that we will achieve our expectations or (2) concerning any result or the timing thereof, in each case, with respect to any regulatory action, administrative proceedings, government investigations, litigation, warning letters, consent decree, cost reductions, business strategies, earnings or revenue trends or future financial results. Forward- looking financial information and other metrics presented herein represent our key goals and are not intended as guidance or projections for the periods presented herein or any future periods. We do not undertake or assume any obligation to update publicly any of the forward- looking statements in this presentation to reflect actual results, new information or future events, changes in assumptions or changes in other factors affecting forward-looking statements. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements. We caution you not to place undue reliance on any forward-looking statements, which are made only as of the date of this presentation.EBITDA, adjusted EBITDA, adjusted diluted profit (loss) per ordinary share and adjusted profit (loss) attributable to the parent are, we believe, pertinent non-IFRS financial metrics that Ferroglobe utilizes to measure its success. Ferroglobe has included these financial metrics to provide supplemental measures of its performance. The Company believes these metrics are important because they eliminate items that have less bearing on the Company’s current and future operating performance and highlight trends in its core business that may not otherwise be apparent when relying solely on IFRS financial measures. For additional information, including a reconciliation of the differences between the non-IFRS financial measures and the comparable IFRS financial measures, refer to the press release dated August 30, 2017 accompanying this presentation, which is incorporated by reference herein.
