Insights

Demand softness drives lower sales; cost mix cushions EBITDA.

Ferroglobe delivered Q3 sales of $311.7M amid weak end-markets and low‑priced imports into the EU. Despite volumes declining across categories, pricing firmed slightly, and product mix plus cost actions supported $18.3M in adjusted EBITDA. Segment detail shows silicon metal and silicon‑based alloys margins improving even as revenue fell.

Cash generation remained intact: operating cash flow was $20.8M and free cash flow $1.6M. Liquidity appears stable with total cash of $121.5M and adjusted gross debt of $126.7M, yielding modest net debt. Working capital decreased quarter over quarter, helped by lower receivables.

Management referenced a strong preliminary U.S. antidumping/countervailing decision and expected EU trade measures, which could influence 2026 conditions; actual impact depends on final outcomes and market demand. The quarterly dividend of $0.014 per share continues, while share repurchases paused due to the current environment.

Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “Market conditions remained challenging in the third quarter, with continued weak demand across our end markets, further pressured by aggressively low-priced imports to the EU. Encouragingly, the strong preliminary decision in the U.S. silicon metals antidumping and countervailing duty case bodes well for 2026. At the same time, we expect the final EU trade measures to be announced later this month. Together, these trade measures should help domestic producers regain market share. As the leading domestic producer in both Europe and the U.S., we are optimistic that 2026 market conditions will be significantly more favorable for Ferroglobe.

“We are further strengthening our partnership with Coreshell through a recently signed joint development agreement as they advance silicon anode technology in EV batteries. Pilot battery deliveries to leading OEMs have already begun, a key milestone toward commercialization. I’m also excited to announce that Coreshell won the prestigious Startup World Cup, a global competition featuring over 1000 regional competitors across more than 20 countries,” concluded Dr. Levi.

Consolidated Sales

In the third quarter of 2025, Ferroglobe reported sales of $311.7 million, a 19.4% decrease from the prior quarter and a 28.1% decrease from the comparable prior-year period. This decrease compared to the prior quarter was mainly driven by lower sales volumes, partially offset by higher pricing across our product portfolio. Sales of silicon metal, silicon-based alloys and manganese-based alloys decreased by $31.1 million, $19.3 million and $21.7 million, respectively, compared with the prior quarter.

Manganese-based alloy revenue in the third quarter was $84.4 million, a decrease of 20.5% from the prior quarter. The average selling price increased by 0.8%, while shipments decreased by 21.1% compared to the prior quarter due to reduced carbon steel production and weakness in the construction and automotive sectors. Adjusted EBITDA for the manganese-based alloys portfolio decreased to $4.4 million for the third quarter, compared with $16.8 million in the prior quarter. The


adjusted EBITDA margin decreased due to weaker European steel demand, higher raw material costs and lower fixed cost absorption.

Raw materials and energy consumption for production

Raw materials and energy consumption for production was $180.4 million in the third quarter of 2025, compared to $253.2 million in the prior quarter, a decrease of 28.7%. As a percentage of sales, raw materials and energy consumption for production declined to 57.9% in the third quarter of 2025, compared to 65.5% in the second quarter. The decrease in costs as a percentage of sales was driven by enhanced operational efficiency, targeted cost optimization, and a more profitable product mix, improving overall profitability despite lower volumes.

Net (Loss) Attributable to the Parent

In the third quarter of 2025, net loss attributable to the parent was $12.8 million, or $(0.07) per diluted share, compared to a net loss attributable to the parent of $10.5 million, or $(0.06) per diluted share in the prior quarter. The quarterly result weakened compared to the previous quarter, reflecting lower sales volumes and reduced operating performance, partly mitigated by cost efficiencies and a favorable product mix. The Company reported adjusted diluted earnings per share of $(0.02) for the third quarter, compared with adjusted earnings per share of $(0.08) in the prior quarter.


Adjusted EBITDA

Adjusted EBITDA was $18.3 million for the third quarter of 2025 compared to $21.6 million for the prior quarter. Adjusted EBITDA was slightly down versus the previous quarter, reflecting ongoing market softness and reduced sales volumes, partially mitigated by operational efficiency improvements.

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

Total cash was $121.5 million as of September 30, 2025, down $14.1 million from $135.5 million as of June 30, 2025. Adjusted gross debt increased by $1.5 million to $126.7 million, resulting in net debt of $5.2 million as of September 30, 2025, a decrease of $15.6 million from the prior quarter.

During the third quarter, cash flows from operating activities were $20.8 million, and net cash used in investing activities was $18.4 million. Cash used in financing activities was $15.8 million as a result of principal repayments on financing facilities in the U.S., South Africa, Norway, France and Spain of $17.3 million, lease payments of $3.4 million, dividend payments of $2.6 million, interest payments of $2.2 million, and the principal repayments of other financing liabilities of $0.6 million, partially offset by net cash proceeds from the sale of short-term commercial paper totaling $10.4 million.

Total working capital was $421.6 million as of September 30, 2025, a decrease of $19.2 million from $440.8 million on June 30, 2025. The decrease in our working capital balance during the quarter was due to a $63.9 million decrease in trade receivables and other receivables, partially offset by increases of $43.4 million in inventories and a $1.3 million decrease in trade and other payables.

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “Despite a challenging market, we generated positive free cash flow and adjusted EBITDA in the third quarter. Our strong working capital management and prudent expense control enabled us to maintain a solid cash position. Due to the current business environment, the company abstained from


share repurchases during the quarter. However, we remain committed to returning cash to shareholders through dividends and opportunistic share repurchases.”

Capital Returns

During the third quarter, Ferroglobe did not repurchase shares and paid a quarterly cash dividend of $ 0.014 per share on September 29, 2025. Our next cash dividend of $0.014 per share will be paid on December 29, 2025, to shareholders of record as of December 22, 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," “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 November 5, 2025 accompanying this presentation, which is incorporated by reference herein.
