Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “The first quarter results reflect an inflection point for our business which is underpinned by solid supply-demand fundamentals across all products in our portfolio. The overall pace of recovery is certainly stronger than what we were expecting and there is now reason to believe these robust conditions will continue for the remainder of the year.” Dr. Levi added, “Ferroglobe has been making progress on multiple fronts. Given the operational and financial improvements we have been pursuing as part of the strategic plan, the Company is well positioned to capitalize on this opportunity and accelerate the path to profitability.”

Cash Flow and Balance Sheet

Cash generated from operations during Q1 2020 was $18.3 million and free cash flow was $9.1 million.

Working capital decreased by $5.9 million, from $339.6 million as of March 31, 2021 to $333.7 million at December 31, 2020. The decrease is mainly driven by continued improvement in inventory, despite the increase in overall activity during the quarter.

Gross debt was $419 million as of March 31, 2021, down from $455 million as of December 31, 2020, primarily as a result of a repayment of our prior Asset Based Loan ($31.3), as part of the overall refinancing, as well as the senior unsecured notes coupon payment ($16.4).

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “This quarter’s results reinforce the leverage to pricing of our business platform. With an improved top-line, driven primarily by higher prices, coupled with our continued effort on driving down costs, we did see some recovery in our margin, although we are far from the full potential of this Company.” Ms. García-Cos added, “Funding for the initial tranche of debt under the new comprehensive refinancing structure comes at an opportune time. The incremental cash provides the ability to fund the execution of the transformation plan, as well as invest in the business in order to capitalize on this strong market backdrop.”

As of March, 28, 2021, the Company announced the agreement in principle on terms of capital raise, extension of bond maturity and entry into a Lock-Up agreement. The transaction involves three, inter-conditional elements: the raising of $40 million of new equity, $60 million of new senior secured notes and the extension of maturity and amendment of the terms of the existing 2022 Senior Notes. The Lock-Up Agreement binds its parties to support and implement the aforementioned transaction, subject to its terms and conditions.

COVID-19

COVID-19 has been and continues to be a complex and evolving situation, with governments, public institutions and other organizations imposing or recommending, and businesses and individuals implementing, at various times and to varying degrees, restrictions on various activities or other actions to combat its spread, such as restrictions and bans on travel or transportation; limitations on the size of in-person gatherings, restrictions on freight transportations, closures of, or occupancy or other operating limitations on work facilities, and quarantines and lock-downs.

As a result of this pandemic and the strict confinement and other public health measures taken around the world, the demand of our products in the second and third quarters of 2020 was reduced significantly compared with the first and fourth quarters of the year. During the fourth quarter of 2020, demand level for our products increased to levels similar to those prior to the outbreak. In first quarter of 2021, demand for our products has increased even further than in the fourth quarter of 2020. However, COVID-19 has negatively impacted, and will in the future negatively impact to an extent we are unable to predict, our revenues.

The main source of finance for the Company are the Senior Notes (the “Notes”) amounting $350,000 thousand due March 1, 2022. The Indenture governing the Notes includes provisions which, in the event of a change of control, would require the Company to offer to redeem the outstanding Notes at a cash purchase price equal to 101% of the principal amount of the Notes, plus any accrued and unpaid interest. Based on the provisions cited above, a change of control as defined in the indenture is unlikely to occur, but the matter it is not within the Company’s control. If a change of control were to occur, the Company may not have sufficient financial resources available to satisfy all of its obligations. Management is pursuing additional sources of financing to increase liquidity to fund operations.

Beginning in 2020, we engaged in discussions with the Ad Hoc Group Noteholders to put forward a plan to refinance the Notes and restructure our balance sheet. On March 27, 2021, Ferroglobe entered into a Lock-Up Agreement with members of an “Ad Hoc-Group”, being existing note holders representing in aggregate approximately 60% of the Notes, to issue additional $60m Notes and with Tyrus Capital (“Tyrus”) as backstop provider in respect of a $40 million equity raise forming part of the transaction. The principal elements of the restructuring, as set forth below, are inter-conditional and must be completed by September 28, 2021, unless extended by agreement.

Management acknowledges that the events and conditions relating to the uncertainty over the completion of the restructuring of the Notes, the potential repayment of the outstanding balance of the Notes should a change of control occur, and the difficulties in forecasting net cash flows in the current economic conditions because of the Covid-19 pandemic, together in aggregate give rise to a material uncertainty that may cast substantial doubt on the ability of the Company to continue as a going concern for a period of twelve months following the date our consolidated financial statements are issued. Notwithstanding the material uncertainty described above, management believes that the Group has adequate resources and considers it likely that the exchange of the Notes and additional capital will be completed, that will allow the Group to continue in operational existence for the foreseeable future. The consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as going concern.

Subsequent events

On April 21, 2021, the Company obtained the agreement in principle of 95.92% (by value) of the noteholders to restructure the Senior Notes and extend their maturity to December 2025. In light of this, the Company agreed an amendment to the Lock-Up Agreement to allow it to proceed to implement the transaction by way of an exchange offer instead of an English law scheme of  arrangement. Although over 96% of the noteholders have now contractually agreed to support the transaction, there can nonetheless be no assurance that the proposed restructuring will be completed.

On April 30, 2021, Mr. José María Alapont resigned from the Board of Directors. Subsequently, on May 13, 2021, Ferroglobe appointed four new board directors and appointed Mr. Bruce Crockett as the Lead Independent Director.

On May 10, 2021, the Company filed a Form F-3 with the United States Securities and Exchange Comission to register a total amount of $40 million in securities. It describes the general terms of these securities and the general manner in which these securities will be offered.

Finally, on May 12, 2021, the Company entered into a Note Purchase Agreement with the members of the “Ad Hoc Group” relating to the issuance of an initial $40 million of aggregate $60 million new senior secured notes. The conditions precedent to the Note Purchase Agreement have been satisfied and the initial $40 million is in the process of being settled.

Sales Prices & Volumes By Product

During Q1 2021, total product average selling prices increased by 9.3% versus Q4 2020. Q1 average selling prices of silicon metal increased 1.1%, silicon-based alloys prices increased 8.9%, and manganese-based alloys prices increased 13.8%.

Sales volumes in Q1 growth by 2.4% versus the prior quarter. Q1 sales volumes of silicon metal increased 11.6%, silicon-based alloys increased 7.4%, and manganese-based alloys decreased 7.6% versus Q4 2020.

Cost of Sales

Cost of sales was $250.2 million in Q1 2021, a decrease from $272.6 million in the prior quarter. Cost of sales as a percentage of sales decreased to 69.2% in Q1 2021 versus 85.1% for Q4 2020. This decrease is mainly due to improved production costs driven by attractive energy rates, continued efficiency, and higher fixed cost absorption.

Other Operating Expenses

Other operating expenses amounted to $36.8 million in Q1 2021, an increase from $29.1 million in the prior quarter. Mainly consequence of a one-off input in Q4 2020 driven by a reclassification to cost of sales to conform the group presentation.

Net Loss Attributable to the Parent

In Q1 2021, net loss attributable to the Parent was $67.4 million, or ($0.40) per diluted share, compared to a net loss attributable to the Parent of $139.1 million, or ($0.82) per diluted share in Q4 2020.

Adjusted EBITDA

In Q1 2021, adjusted EBITDA was $22.1 million, or 6.1% of sales, compared to adjusted EBITDA of $5.5 million, or 1.7% of sales in Q4 2020. The increase in the Q1 2021 Adjusted EBITDA is primarily driven by increased realized pricing, improved costs and the avoidance of one-off, non-recurring costs during the quarter.

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”, “target”, “will” and words of similar meaning or the negative thereof.

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.

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 referenced herein or any future periods.

All information in this press release is as of the date of its release. Ferroglobe does not undertake any obligation to update publicly any of the forward-looking statements contained herein to reflect new information, events or circumstances arising

after the date of this press release. You should not place undue reliance on any forward-looking statements, which are made only as of the date of this press release.

Non-IFRS Measures

Adjusted EBITDA, adjusted EBITDA margin, adjusted net profit, adjusted profit per share, working capital and net debt, 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," “aim,” “target,” 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 not 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. Adjusted EBITDA, adjusted EBITDA margin, adjusted net profit, adjusted profit per share, working capital and net debt, are non-IFRS financial metrics that, we believe, are pertinent measures of Ferroglobe’s 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 May 17, 2021 accompanying this presentation, which is incorporated by reference herein. 2

I.Q1 2021 Business Review

I KEY HIGLIGHTS Ferroglobe • Q1-21 results: • • • • Sales of $361.4 million,compared to $320.5 million in Q4-20 and $311.2 million in Q1-20 Adjusted EBITDA of $22.1 million compared to $5.5 million in Q4-20 and ($17.6) million in Q1-20 Net loss of ($68.5) million,compared to a net loss of ($139.8) million in Q4-20 and net loss of ($49.1) in Q1-20 Positive operating cash flow of $18.3 million in Q1-21 • Key drivers impacting quarterly results: • • • Strong pace of recovery supporting higher shipments and pricing across product portfolio Improved production costs driven by better energy terms, continued efficiency,and higher fixed cost absorption One-time costs associated with repurchase of previously sold C02 credits • Working capital • $333.7 million at the end of Q1-21,a decrease of $5.9 million, from the year end 2020 balance of $339.6 million • Despite the increase in activity in the quarter, the working capital has remained stable mainly driven by a tight control on inventory levels Gross debt reduction of $36.5 million during the quarter,with a balance of $418.6 million, from the Dec. 31,2020 balance of $455.1 million • Net debt increased by $10.8 million with a balance of $334.3 million as of Mar. 31,2021 from the Dec.31,2020 balance of $323.5 million Cash balance of $84 million as of Mar. 31,2021. The reduction in cash is due to the repayment of the prior asset based loan in the United States, and corresponding payments for ancillary services as part of the comprehensive refinancing,coupled with the payment of the coupon tied to the senior unsecured notes • • 6

Additionally, in Q4 staff costs were reduced by the COVID assistance to employment in the US and Canada Operating loss of ($7.7) million is an improvement of 92%, compared to Q4-20 Net finance expense has decreased by 20% in Q1 as Q4 had a higher expense due to refinancing of the securitization program Negative impact of FX by $9.3m in Q1-21 driven the strengthening of the USD against the EUR

ADJUSTED EBITDA BRIDGE Q1-21 to Q4-20 ($m) • Volume: increase of 2% — increased activity in silicon metal and silicon-based alloys, partially offset with decrease in Mn-based alloys • Pricing: average realized pricing increased by 12%, quarter-over-quarter — improved pricing across all product categories • Costs: benefited from lower electricity prices and increased fixed cost absorption due to higher production • Head Offices: The variance is mainly due to the timing of external services rather than an overspend for the year • Non-recurring items driven mainly by fair market value adjustment in relation to the CO2 price • Non-core business for the quarter is mainly driven by a better result in mining operations ($0.9 million) 12
