(2) Free cash flow is calculated as operating cash flow less capital expenditures

Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “2024 was a successful year for Ferroglobe with many accomplishments. We achieved an adjusted EBITDA per our guidance and generated strong free cash flow, which was used to repay our senior secured notes. This strong free cash flow and balance sheet enabled us to initiate the capital return program, including dividends and share repurchases, while positioning the company for growth. We are optimistic that, while there are uncertainties in the markets, demand will begin improving in the second half of 2025.”

“Material progress has been made in implementing trade measures with the US Department of Commerce, imposing strong final anti-dumping and countervailing duties on Russian ferrosilicon imports while continuing to investigate the cases against Brazil, Kazakhstan, and Malaysia. The European Commission initiated its safeguard investigation into the imports of silicon metals, silicon alloys and manganese alloys into the EU.

Consolidated Sales

In the fourth quarter of 2024, Ferroglobe reported sales of $367.5 million, a decrease of 15.2% over the prior quarter and a decrease of 2.2% from the comparable prior year period. This decrease compared to the prior quarter was primarily attributable to lower sales volumes in our portfolio of products, partially offset by higher tons sold in manganese-based alloys. Sales of silicon metal, silicon-based alloys and manganese-based alloys declined by $32.2 million, $16.7 million and $11.2 million, respectively, compared with the prior quarter.

For the full year 2024, sales were $1,644 million versus $1,650 million in the prior year, a decrease of 0.4%. This decrease was mainly driven by a 17.6% decrease in silicon-based alloys revenue, partially offset by a 28.4% increase in Manganese-Based Alloys revenues.

U.S. Silicon Metal Producers File Petitions to Stop Unfairly Traded Imports from Angola, Australia, Laos, Norway, and Thailand

WASHINGTON, DC, April 24, 2025 – Ferroglobe USA, Inc. (“Ferroglobe”) and Mississippi Silicon LLC (“Mississippi Silicon”), representing all American silicon metal production, today filed petitions with the U.S. Department of Commerce (“Commerce”) and U.S. International Trade Commission (“ITC”) asking both agencies to investigate unfairly priced and subsidized silicon metal imports from Angola, Australia, Laos, Norway, and Thailand that are causing material injury to U.S. industry.

Silicon metal is a highly refined raw material composed almost entirely of elemental silicon. Silicon metal is critical to the production of multiple products related to national security, including aluminum, silicones, and polysilicon, which is then used in semiconductor, solar, and electronics applications.

The antidumping and countervailing duty petitions detail unfair trade practices to sell silicon metal at less than fair value and allege dumping margins of up to 337.84%, as well as numerous subsidies. The petitions detail the extensive injury suffered by the U.S. industry and its workers, and request relief in the form of special duties on all associated imports.

“American silicon metal producers can compete with anyone in the world, but these imports are not playing by the rules and are devastating the domestic industry and its workers as a result,” said Eddie Boardwine, Chief Executive Office of Mississippi Silicon. “However, our country’s trade laws are there to defend American manufacturing when faced with unfair trade. On behalf of our employees, customers, and community, we look forward to seeing those laws enforced and a return to fair competition in the U.S. market.”

~~Silicon-Based~~The ~~Alloys~~cases filed today cover all forms and sizes of silicon metal, which contains at least 85.00 percent but less than 99.99 percent silicon, and less than 4.00 percent iron, by actual weight.

The next steps in these investigations will be the initiation of Commerce’s antidumping and countervailing duty investigations by May 14, 2025. A preliminary ITC determination is expected by June 9, 2025.

Manganese-based Alloys Adj.EBITDA Margin		9.0%		31.0%			39.5%			16.3%		14.7%

Manganese-based alloy revenue in the fourth quarter was $78.5 million, a decrease of 12.5% over the prior quarter and an increase of 29.8% from the year-ago period. The average realized selling price decreased by 16.7% and total shipments increased by 5.0%. Adjusted EBITDA for the manganese-based alloys portfolio decreased to $7.1 million in the fourth quarter of 2024, a decrease of 74.5% compared with $27.9 million in the prior quarter. The decrease in adjusted EBITDA margin was mainly driven by lower selling prices and higher manganese ore costs.

Raw materials and energy consumption for production

Raw materials and energy consumption for production was $250.8 million in the fourth quarter of 2024 versus $255.1 million in the prior quarter, a decrease of 1.7%. As a percentage of sales, raw materials and energy consumption for production was 68.2% in the fourth quarter of 2024, compared to 58.8% in the third quarter. The increase in cost as a percentage of sales was driven by higher energy and raw materials costs, including manganese ore.

For the full-year 2024, raw materials and energy consumption for production were $1,027 million, or 62.5% of sales, versus $879 million, or 53.3% of sales in 2023. The increase in these costs as a percent of sales was mainly driven by lower prices and higher energy costs.

Net (Loss) Income Attributable to the Parent

In the fourth quarter of 2024, net loss attributable to the parent was $46.4 million, or $(0.25) per diluted share, compared to a net income attributable to the parent of $18.8 million, or $0.10 per diluted share in the third quarter. This decrease is primarily attributable to $61.3 million recorded in impairment of the Company’s cash-generating units which were not recorded in the prior period. The Company reported adjusted diluted earnings per share of $0.03 for the fourth quarter, compared with adjusted earnings per share of $0.11 per share in the prior quarter.

For the full year 2024, net profit attributable to the parent was $5.2 million, or $0.03 per diluted share, compared to $82.7 million, or $0.43 per diluted share for the full year 2023.

Adjusted EBITDA

In the fourth quarter of 2024, adjusted EBITDA was $9.8 million, or 2.7% of sales, a decrease of 11.3% compared to adjusted EBITDA of $60.4 million, or 13.9% of sales, from the third quarter of 2024. This was mainly driven by higher costs and reduced pricing.

For the full year 2024, adjusted EBITDA was $153.8 million, or 9.4% of sales, compared to adjusted EBITDA of $315.2 million, or 19.1% of sales, for the full year 2023. The reduction is largely related to lower average sales prices and an increase in energy costs.

(2) Adjusted gross debt excludes bank borrowings on factoring program and impact of leasing standard IFRS16 for each of the periods presented(3) Total working capital comprised of inventories, trade receivables and other receivables minus trade and other payables

The Company’s total cash was $133.3 million as of December 31, 2024, up $12.5 million from $120.8 million as of September 30, 2024.

During the fourth quarter, the Company generated $32.1 million in cash flow from operating activities, used $4.8 million in cash flows from investing activities and used $9.9 million in cash flows from financing activities due to repayments of bank borrowings of $14.8 million, lease payments of $4.5 million, dividend payments of $2.4 million, interest payments of $2.0 million and share repurchases of $1.9 million, partially offset by cash proceeds from promissory notes of $10.3 million and sale-leaseback financing of $6.1 million.

For the full year 2024, the Company generated $243.3 million of operating cash flow and used $66.9 million of cash in investing activities and $175.5 million in financing activities.

Total working capital was $460.8 million on December 31, 2024, down from $528.6 million on September 30, 2024. The $67.8 million decrease in working capital balance during the quarter was due to a $60.6 million decrease in inventories, and a $37.3 million decrease in trade and other receivables, partially offset by a $30.1 million decrease in trade and other payables.

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “We achieved many of our targets in 2024, including paying off our senior secured notes and achieving a net cash positive position, which was $38.9 million, at the end of the year. We reduced our total working capital by approximately $50 million during the year and initiated our capital return program consisting of quarterly dividends and share repurchases.”

Capital Returns

During the fourth quarter, Ferroglobe repurchased 481,578 shares at an average price of $4.02 per share and paid a quarterly cash dividend of $0.013 per share on December 20, 2024. Our next cash dividend of $0.014 per share will be paid on March 26, 2025, to shareholders of record as of March 20, 2025.

NASDAQ: GSM Forward-Looking Statements and Non-IFRS Financial Metrics 2 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 energy and other raw materials; (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 operational risks including industrial accidents and natural disasters; (x) ability to manage a global footprint; (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, 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, adjusted gross debt, net cash 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 February 19, 2025 accompanying this presentation, which is incorporated by reference herein.
