“Following strong growth in our business over several sequential quarters, market conditions in our main products deteriorated through Q3,” said Pedro Larrea, CEO of Ferroglobe. “However, Ferroglobe is still showing solid results overall for the first nine months of 2018, with adjusted EBITDA up 69% year-over-year to $220.9 million, leverage remaining below 2.0x and a comfortable liquidity position.”

Mr. Larrea continued: “In response to the evolving markets for our key products, Ferroglobe has taken swift action to optimize our position across our global production base. In this regard, we are curtailing production in our silicon metal and manganese-based alloys businesses in order to take advantage of our diversified portfolio by optimizing production among our most cost effective plants and geographies. We also continue to look at further measures to control our costs, to draw down inventories, and to enhance our free cash flow profile. That said, we are operating in a volatile environment currently and our financial results may continue to be challenged in the near-term.”

Cash Flow and Balance Sheet

Cash used for operations during Q3 2018 was $7.9 million, with working capital increasing by $36.0 million. Net debt was $510.9 million as of September 30, 2018, up from $475.3 million as of June 30, 2018. “We did not meet our cash flow goals in the third quarter,” said Phillip Murnane,  Ferroglobe’s CFO. “The deterioration in market conditions during the quarter left us with elevated inventories, a key factor in our decision to curtail our production.”

“Generating free cash flow through improvements in operations, reductions in working capital, non-core asset sales, and lowered interest expense remains our top priority” added Mr. Murnane. “Given our Q3 results, our free cash flow targets for the second half of 2018 have become a ‘stretch’  goal.  Regarding the potential refinancing of our $350 million of Senior Notes, we will continue to evaluate the credit markets and will act when the timing is right. In the mean time, our financial position remains strong, with total liquidity of approximately $250 million and no material debt maturities until 2022.”

Sales Prices & Volumes By Product

During Q3 2018, the average selling prices decreased by between 5% and 7% for all of our products quarter-over-quarter, reflecting overall market conditions. However, average selling prices for 2018 are well above 2017 for silicon metal and silicon-based alloys, and at levels that are compatible with historical trends. Manganese-based alloys prices in 2018 have significantly deteriorated, despite persistently high ore prices, a situation that should revert going forward based on historical market precedent.

Sales volumes in Q3 also decreased as compared to Q2, primarily as a consequence of seasonal slowdown in Europe and the impact of changing trade flows.  Activity to date in 2018 shows healthy growth, with volume increases over the same period in the prior year of 7% to 8% in silicon metal and silicon-based alloys. A year-to-year comparison of manganese-based alloys volumes is inapt in light of the Company’s acquisition of new manganese-based alloy assets earlier this year.

Cost of Sales

Cost of sales was $334.5 million for the three months ended September 30, 2018, an increase from $267.4 million for the three months ended September 30, 2017, primarily driven by higher input costs for raw materials and energy and higher volumes. Cost of sales was $999.0 million for the nine months ended September 30, 2018, an increase from $758.8 million for the same period in 2017, primarily driven by higher sales and increases in raw materials and energy prices, particularly manganese ore and electrodes. Cost of goods sold as a percentage of sales increased to 63.5% for the three months ended September 30, 2018 from 59.2% for the three months ended September 30, 2017, whilst for the nine months ended September 30, 2018, cost of sales as a percentage of sales was 59.8% compared to 59.6% for the nine months ended September 30, 2017.

Staff Costs and Other Operating Expenses

Staff costs and other operating expenses for the three months ended September 30, 2018 and the nine months ended September 30, 2018 were $153.2 million and $470.6 million, respectively compared to $133.9 million and $399.7 million for the corresponding periods in 2017. The increases were primarily related to labour costs for the newly acquired manganese-based alloy plants.

Operating Profit

Operating profit was $14.3 million and $180.4 million, respectively for the three and nine month periods ended September 30, 2018, compared to $27.3 million and $41.3 million for the three and nine month periods ended September 30, 2017. Included in the nine months ended September 30, 2018 was a $44.6 million bargain purchase gain related to the Company’s purchase of manganese-based alloy plants mentioned above.

Net Loss Attributable to the Parent

As a result of the various factors described above, we reported a net loss attributable to the Parent of $1.2 million, or ($0.01) per diluted share, for the three months ended September 30, 2018 and a net loss attributable to the Parent of $3.3 million, or ($0.02) for the three months ended September 30, 2017. We reported net income of $102.9 million, or $0.60 per diluted share, for the nine months ended September 30, 2018, compared to a net loss of $7.0 million, or ($0.04) per diluted share for the nine months ended September 30, 2017.

Adjusted EBITDA

Adjusted EBITDAof $45.0 million, or 8.5% of sales, for the three months ended September 30, 2018 was lower than adjusted EBITDA of $56.1 million, or 12.4% of sales, for the three months ended September 30, 2017. Adjusted EBITDA of $220.9 million, or 13.2% of sales for the nine months ended September 30, 2018, was higher than adjusted EBITDA of $130.9 million, or 10.3% of sales for the nine months ended September 30, 2017.

Other recent developments

In light of financial performance in Q3 2018, near-term market outlook and the Company’s continued focus on cash generation and deleveraging its balance sheet, no interim dividend has been declared or is payable in respect of Q3 2018.

On August 21, 2018 the Company announced a $20 million programme for the purchase of its ordinary shares. 2,894,049 ordinary shares in the Company have been purchased under the programme, of which 1,152,958 shares have been cancelled and 1,741,091 are held in Treasury. The average price paid per share was $6.89. The programme closed on November 7, 2018.

Ferroglobe’s Executive Chairman, Javier López Madrid, has advised the Company that, on October 3, 2018, the Supreme Court of Spain (Tribunal Supremo) substantially confirmed the ruling of the Spanish High Court (Audiencia Nacional) in the case related to the misuse of corporate credit cards by 65 former directors and executives of Bankia S.A and/or Caja Madrid, including Mr López Madrid. The proceeding against Mr López Madrid relates to expenditure totalling €34,807.81 incurred between 2010 and 2012 and has been previously disclosed by the Company in its regulatory filings and its press release of March 16, 2017. Mr. López Madrid has advised the Company that, pursuant to the legal framework applicable to this case, he has applied for a suspension or a replacement of his sentence with the payment of a fine of €7,120.  The Company’s Board of Directors has closely monitored the developments in this case, agreed that Mr. López Madrid remain as a director of the Company and continues to support him in his role as Executive Chairman.

Forward-looking statements contained in this press release are based on information currently available to the Company and assumptions that management 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.

Non-IFRS Measures

EBITDA, adjusted EBITDA, adjusted diluted profit per ordinary share and adjusted profit are non-IFRS financial metrics that, we believe, are pertinent measures of Ferroglobe’s 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 and non-IFRS Financial Metrics This presentation contains forward-looking statements within the meaning of Section 27A of the United States Securities Act of 1933, as amended, and Section 21E of the United States Securities Exchange Act of 1934, as amended. Forward-looking statements are not historical facts but are based on certain assumptions of management and describe our future plans, strategies and expectations. 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 Ferroglobe PLC (“we,” “us,” “Ferroglobe,” the “Company” or the “Parent”) 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 Ferroglobe will not successfully integrate the businesses of Globe Specialty Metals, Inc. and Grupo FerroAtlántica SAU, that we will not realize estimated cost savings, value of certain tax assets, synergies and growth, and/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 Ferroglobe are, we believe, pertinent non-IFRS financial metrics that Ferroglobe utilizes to measure its success. The Company has included these financial metrics to provide supplemental measures of its performance. We believe 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 such non-IFRS financial measures and the comparable IFRS financial measures, refer to the press release dated November 26, 2018 accompanying this presentation, which is incorporated by reference herein.

Conservative capital structure — company positioned to pursue growth opportunities Focus on deleveraging the balance sheet Reduction in net leverage, leverage below target of 2x in Q1 2018, Q2 2018 and Q3 2018 Continued commitment to further lowering leverage, will not meet 1.5x by year end Refinancing of the “9.375% 2022 Senior Notes” will continue to be evaluated and we will act when the timing is right Solar-grade silicon plant construction and ramp up adjustments to balance cash flows Design changes to increase capacity will result in capex increase by ~10% to €58.5 million (long term benefit) However, the decision to delay ramp up will allow a reduction in total capex deployment to €46 million in 2018 +2019 (near term cash management) — €30 million in 2018 — €16 million in 2019 In light of financial performance in Q3 2018, near-term market outlook and the Company’s continued focus on cash generation and deleveraging its balance sheet, no interim dividend has been declared or is payable in respect of Q3 2018 Q3 2018 Performance Remain Focused on Generating Cash-flow Reported EBITDA of $45.0 million, -66% vs reported EBITDA of $130.9 million in Q2 2018 Adjusted EBITDA of $45.0 million for the quarter, -48% vs Adjusted EBITDA of $89.3 million in Q2 2018 Net Loss of -$2.9 million for the quarter and Adjusted Net Profit of $0.1m for the quarter, or $0.00 on a fully diluted per share basis Working capital increased to $443.3 million during the quarter, primarily driven by build in finished inventory Operating cash flow of $-7.9 million and free cash flow of $-33.7 million for the quarter Net debt of $510.9 million at end of Q3 2018, up from $475.3 million at the end of Q2 2018 — largely attributable to the working capital build Net Debt to LTM EBITDA ratio remains below 2x Delivering value for shareholders and positioning Ferroglobe for the long-term

However, silicon metal industry sentiment of oversupply may impact short term decisions Quarterly Global Silicon Metal Supply/Demand Trends Factors Impacting the Supply-Demand Dynamics in the Near Term Most previously idled capacity has restarted over the past 18 months Higher than usual level of inventories at customers through Q2 and Q3 Low prices of aluminium scrap in North America affecting demand for silicon metal Major producers running close to capacity Oversupply projected by analysts in the short term, although limited to around 50,000 tons/year worldwide Cost inflation leading marginal producers towards loss-making situation Source: CRU (‘000 t)

Ferroglobe has taken action to optimize its global production footprint – Silicon Metal Ferroglobe Silicon Metal Capacity (´000 tons Annualized) -40k tons -36k tons (‘000 t) Rationale for Capacity Cutbacks Expected Results Inventories above desired level Suboptimal operation, with multiple facilities running at reduced load Potential of having loss making facilities: Selma (being idled), Mendoza Loss making production of CaSi and foundry products in Argentina transferred to more efficient Château-Feuillet (France) plant Loss making production of FeSi in Furnace 3 at Sabón (Spain) transferred to more efficient Laudun (France) plant Cost savings, by closing Selma and concentrating production in more efficient plants: $5.4 million Potential to increase Silicon Metal capacity, if needed, by running Furnace 3 at Sabón Source: Ferroglobe Silicon Metal capacity reductions: Selma, AL (2 furnaces) Beverly, OH (1 furnace) Château-Feuillet, France: 2 furnaces Laudun, France: 1 furnace 218 127 59 178 91 59 0 50 100 150 200 250 Europe North America South Africa March 2018 Pro Forma for planned changes

Rationale for Capacity Cutbacks Expected Results Inventories above desired level. Loss making facilities Cost optimization across the platform Reduction of stock levels. EBITDA improvements around $2.3m in Q4. Flexibility to increase production in Q1 or Q2 if market conditions improve.

Outlook for 2019 Contracting season progressing slower than usual — customers trying to make case for lower prices while producers faced with increasing costs and seeing stable demand Some lingering impact of aluminum scrap in North America and auto emissions issue in Europe starting to play a role Maintaining disciplined commercial approach Silicon Metal Ferrosilicon — preference for short term, quarterly contracts, particularly in Europe, or for indexed in the case of the bigger customers — consistent with the past Increased volume expected in the ferrosilicon specialty grades with good momentum in the order book Foundry business growth continues Normal pace of contracting, with some very significant orders already booked Some signs of price recovery in ferromanganese Strong demand of refined products, with higher margin Secured some very significant orders from the most relevant customers Improved production cost through a stricter choice of manganese ore mix Silicon-Based Alloys Mn-Based Alloys Commercial outlook across our portfolio for 2019

Challenges faced in Q3 likely to continue in the near-term Strong liquidity and balance sheet with a focus on positive free cash flow in 2019 Fundamental asset value based on strong market position and platform diversification Closing remarks
