Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “While market conditions remained challenging in the fourth quarter, we are encouraged by the clear progress on trade enforcement that is reshaping the competitive landscape. The strong preliminary decision in the U.S. silicon metal antidumping and countervailing duty case, together with the finalization of EU trade measures, meaningfully strengthen the outlook for 2026. These actions should enable domestic producers to regain market share and support healthier market conditions.

“As a leading domestic producer in both Europe and the U.S., and with a strong balance sheet, disciplined cost control, and a competitive long-term French energy agreement in place, we are optimistic that 2026 will mark a substantial improvement in market conditions and financial performance for Ferroglobe,” concluded Dr. Levi.

Consolidated Sales

In the fourth quarter of 2025, Ferroglobe reported sales of $329.4 million, a 5.7% increase from the prior quarter and a 10.4% decrease from the comparable prior-year period. The sequential improvement was mainly driven by higher sales volumes of silicon-based alloys and manganese-based alloys, partially offset by lower silicon metal volumes and lower pricing of silicon-based alloys and manganese-based alloys. Silicon metal prices remained stable during the quarter. Sales of silicon metal decreased by $2.5 million, while silicon-based alloys and manganese-based alloys increased by $11.2 million and $8.2 million, respectively, compared with the prior quarter.

For the full year 2025, sales were $1,335 million versus $1,644 million in the prior year, a decrease of 18.8%. This decrease was mainly driven by a 40.8% and 1.4% decrease in silicon metal and silicon-based alloys revenue, respectively, partially offset by a 7.5% increase in manganese-based alloys revenues.

Silicon Metal Adj.EBITDA Margin		0.9%		11.7%			10.4%			0.8%		14.9%

Silicon metal revenue in the fourth quarter was $96.5 million, a decrease of 2.5% from the prior quarter. The average selling price increased 0.2%, driven by higher pricing in the U.S. and South Africa, partially offset by softer pricing in Europe, where demand remained subdued, particularly in the chemical sector. Shipments decreased 2.8% mainly reflecting lower volumes in the U.S., partially offset by higher volumes in EMEA. Adjusted EBITDA decreased to $0.9 million in the fourth quarter, compared with $11.6 million in the prior quarter, primarily due to lower volumes and reduced fixed cost absorption, mainly related to furnace shutdowns in France.

Silicon-based alloy revenue in the fourth quarter was $103.6 million, an increase of 12.2% from the prior quarter. The average selling price decreased by 6.0%, primarily due to lower pricing in the U.S. and Europe, partially offset by higher pricing in South Africa. Shipments increased by 19.3% reflecting a broad-based volume improvement across regions, with the strongest increase in EMEA. In Europe, safeguard measures implemented on certain ferroalloy imports began to reduce import pressure and supported order activity late in the quarter. Adjusted EBITDA increased to $15.5 million in the fourth quarter of 2025, up 25.1% compared with $12.4 million in the prior quarter, driven by higher volumes. Adjusted EBITDA margin improved to 15.0% in the fourth quarter, compared with 13.4% in the prior quarter, highlighting the benefits of stronger volume leverage and continued cost discipline.

Manganese-based Alloys Adj.EBITDA Margin		9.4%		5.2%			9.0%			6.8%		16.3%

Manganese-based alloy revenue in the fourth quarter was $92.7 million, an increase of 9.7% from the prior quarter. The average selling price decreased by 5.5%, reflecting broadly lower pricing in the U.S. and EMEA. Shipments increased by 16.1% compared to the prior quarter driven by a significant volume increase in Europe. In EMEA, safeguard measures for

certain ferroalloy imports began to ease import pressure and supported improved order flows during the quarter. Adjusted EBITDA for the manganese-based alloys portfolio increased to $8.7 million for the fourth quarter, compared with $4.4 million in the prior quarter, driven by higher volumes and improved fixed cost absorption. Adjusted EBITDA margin improved to 9.4% in the fourth quarter, compared with 5.2% in the prior quarter, highlighting stronger operating leverage.

Raw materials and energy consumption for production

Raw materials and energy consumption for production totaled $261.6 million in the fourth quarter of 2025, compared with $180.4 million in the third quarter, representing an increase of 45.0%. As a percentage of sales, these costs rose to 79.4% in the fourth quarter of 2025, up from 57.9% in the prior quarter. The increase in costs as a percentage of sales was primarily driven by temporary production curtailments in France, which reduced fixed-cost absorption and increased unit costs, as well as a $40.2 million fair-value loss related to changes in the valuation of our long-term energy contracts, principally in France. Excluding the impact of power purchase agreements, raw materials and energy consumption for production represented 67.2% of revenue.

For the full year 2025, raw materials and energy consumption for production totaled $933.5 million, representing 69.9% of sales, compared with $1,027.0 million, or 62.5% of sales, in 2024. The increase in costs as a percentage of sales was primarily driven by lower realized pricing, a higher energy cost environment throughout the year, and a $41.9 million fair-value loss related to changes in the valuation of our long-term energy contracts, principally in France. In addition, lower production levels in France reduced fixed-cost absorption, further increasing unit costs.

Net (Loss) Attributable to the Parent

In the fourth quarter of 2025, net loss attributable to the parent was $81.0 million, or $(0.43) per diluted share, compared to a net loss attributable to the parent of $12.8 million, or $(0.07) per diluted share in the prior quarter. The quarterly results reflect lower realized pricing, a $40.2 million fair-value loss related to our long-term French energy contracts, higher underlying energy costs, and the impact of temporary production curtailments in France, which reduced fixed cost absorption, offset by higher shipment volumes in our alloy portfolio, ongoing cost efficiencies and a favorable product mix. The Company reported adjusted diluted earnings per share of $(0.06) for the fourth quarter, compared with adjusted earnings per share of $(0.02) in the prior quarter.

For the full year 2025, net loss attributable to the parent was $170.7 million, or $(0.91) per diluted share, compared to a net profit attributable to the parent of $23.5 million, or $0.12 per diluted share for the full year 2024.

Adjusted EBITDA

Adjusted EBITDA was $14.6 million for the fourth quarter of 2025 compared to $18.3 million for the prior quarter. Adjusted EBITDA was slightly down versus the previous quarter, primarily by higher energy-related costs and lower fixed cost absorption associated with temporary production curtailments, partially offset by stronger volumes and continued cost efficiency initiatives.

For the full year 2025, adjusted EBITDA was $27.6 million, or 2.1% of sales, compared to adjusted EBITDA of $153.8 million, or 9.4% of sales, for the full year 2024. The reduction is largely related to lower realized pricing across the portfolio and a weaker performance in silicon metal, driven by a significant decline in volumes. These impacts were partially offset by higher shipment volumes in manganese-based alloys and silicon-based alloys, supported by improved demand and customer restocking in key steel related end markets.

Total cash was $123.0 million as of December 31, 2025, up $1.5 million from $121.5 million as of September 30, 2025. Adjusted gross debt increased by $26.1 million to $152.8 million, resulting in net debt of $29.8 million as of December 31, 2025, an increase of $24.6 million from the prior quarter.

During the fourth quarter, cash flows used in operating activities were $4.3 million, and net cash used in investing activities was $13.1 million. Cash provided in financing activities was $18.6 million as a result of principal proceeds from financing facilities in South Africa, France and Spain totaling $28.2 million, net cash proceeds from the sale of short-term commercial paper totaling $3.1 million, partially offset by lease payments of $6.5 million, dividend payments of $2.6 million, interest payments of $2.9 million, and the principal repayments of other financing liabilities of $0.7 million.

For the full year 2025, the Company generated $51.5 million of operating cash flow, used $73.1 million of cash in investing activities and generated $3.4 million in financing activities.

Total working capital was $427.5 million as of December 31, 2025, an increase of $5.9 million from $421.6 million at the end of the prior quarter. The increase in our working capital balance during the quarter was due to a decrease of $79.9 million in trade and other payables and an increase of $7.8 million in trade receivables, partially offset by $63.2 million and $18.5 decrease in inventories and other receivables, respectively.

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “Our performance reflects a strong emphasis on financial discipline and balance sheet strength. We generated positive adjusted EBITDA in the fourth quarter, while ending the period with $123 million in total cash and modest net debt. This solid financial position provides the flexibility to manage near-term volatility, invest selectively in growth opportunities, and support our increased dividend as we enter 2026.”

Capital Returns

During the fourth quarter, Ferroglobe did not repurchase shares and paid a quarterly cash dividend of $ 0.014 per share on December 29, 2025. Our next cash dividend of $0.015 per share will be paid on March 30, 2026, to shareholders of record as of March 23, 2026.

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," “should," "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, the impacts of the Ukraine-Russia conflict; increases in energy prices, disruptions in the supply of power and changes in governmental regulation of the power sector and the effect on costs of production; the outcomes of pending or potential litigation; operating costs, customer losses and business disruptions (including, without limitation, difficulties in maintaining relationships with employees, customers, clients or suppliers) that may be greater than expected; the retention of certain key employees; the current and anticipated competitive landscape; our ability to adapt products and services to changes in technology or the marketplace; our ability to maintain and grow relationships with customers and clients; the historic cyclicality of the metals industry and the attendant swings in market price and demand; the availability of raw materials and transportation; costs associated with labor disputes and stoppages; our ability to maintain our liquidity and to generate sufficient cash to service indebtedness; the integration and development of prior and future acquisitions; the availability and cost of maintaining adequate levels of insurance; our ability to protect trade secrets, trademarks and other intellectual property; equipment failures, delays in deliveries or catastrophic loss at any of our manufacturing facilities, which may not be covered under any insurance policy; exchange rate fluctuations; changes in laws protecting U.S., Canadian and European Union companies from unfair foreign competition (including antidumping and countervailing duty orders and laws) or the measures currently in place or expected to be imposed under those laws; compliance with, or potential liability under, environmental, health and safety laws and regulations (and changes in such laws and regulations, including in their enforcement or interpretation); risks from international operations, such as foreign exchange fluctuations, tariffs, duties and other taxation, inflation, increased costs, political risks and our ability to maintain and increase business in international markets; risks associated with mining operations, metallurgical smelting and other manufacturing activities; our ability to manage price and operational risks including industrial accidents and natural disasters; our ability to acquire or renew permits and approvals; potential losses due to unanticipated cancellations of service contracts; risks associated with potential unionization of employees or work stoppages that could adversely affect our operations; changes in tax laws (including under applicable tax treaties) and regulations or to the interpretation of such tax laws or regulations by governmental authorities; changes in general economic, business and political conditions, including changes in the financial markets; uncertainties and challenges surrounding the implementation and development of new technologies; risks related to potential cybersecurity breaches; risks related to our capital structure; risks related to our ordinary shares; our foreign private issuer status, the loss of which would require us to comply with the Exchange Act’s domestic reporting regime, and cause us to incur significant legal, accounting and other expenses; our incorporation in the United Kingdom, the laws of which govern our corporate affairs and may differ from those applicable to companies incorporated in the U.S.; and our failure to maintain an effective system of internal control over financial reporting. 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. EBITDA, 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 17, 2026 accompanying this presentation, which is incorporated by reference herein.
