​

Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “Our second quarter results reflect solid execution of our strategy despite a challenging pricing environment. Strong volume growth, positive free cash flow generation, and further debt reduction reinforce the resilience of our operating platform and our disciplined approach to capital allocation.

​

“At the same time, we continue to advance the development of our critical materials strategy by leveraging our existing industrial footprint, metallurgical expertise, and established customer relationships to create new avenues for growth. Combined with increasing support for Western supply chains and domestic production, we believe Ferroglobe is uniquely positioned to benefit from the growing focus on critical materials, industrial security, and onshoring initiatives across the U.S. and Europe,” concluded Dr. Levi.

​

Consolidated Sales

​

In the second quarter of 2026, Ferroglobe reported sales of $378.6 million, an 8.9% increase from the prior quarter and a 2.1% decrease from the comparable prior-year period. The sequential improvement was mainly driven by higher sales volumes of silicon metal and silicon-based alloys, as well as higher average selling prices for manganese-based alloys, partially offset by lower sales volumes for manganese-based alloys and lower average selling prices for silicon metal and silicon-based alloys. Sales of silicon metal increased by $21.7 million, silicon-based alloys increased by $2.6 million, and manganese-based alloys increased by $0.5 million compared with the prior quarter.

​

Silicon metal revenue in the second quarter was $105.8 million, an increase of 25.8% from the prior quarter. The average selling price decreased by 5.9%, driven by lower pricing across the U.S. and EMEA, as elevated market availability and cautious customer purchasing continued to weigh on realized prices, particularly in Europe. Shipments increased 33.7%, reflecting higher volumes in both EMEA and the U.S. Adjusted EBITDA decreased to $(2.7) million in the second quarter, as compared with $(2.3) million in the prior quarter, primarily due to lower realized pricing. Adjusted EBITDA margin improved to (2.5%) in the second quarter from (2.7%) in the prior quarter.

​

Silicon-based alloy revenue in the second quarter was $124.9 million, an increase of 2.2% from the prior quarter. The average selling price decreased by 1.5%, as higher realized prices in South Africa were more than offset by softer pricing in Europe and the U.S. amid subdued steel demand and ample market availability. Shipments increased 3.7%, primarily reflecting stronger volumes in Europe, partially offset by lower volumes in South Africa and the U.S. Adjusted EBITDA increased to $14.5 million in the second quarter of 2026, compared with $6.8 million in the prior quarter, primarily driven by improved operating costs and higher shipments, partially offset by lower realized pricing. Adjusted EBITDA margin increased to 11.6% in the second quarter, compared with 5.6% in the prior quarter.

​

Manganese-based alloy revenue in the second quarter was $107.6 million, an increase of 0.4% from the prior quarter. The average selling price increased by 1.6%, reflecting higher pricing in both Europe and the U.S. In Europe, pricing was

​

supported by the impact of EU safeguard measures and additional duties on certain imports, despite continued weakness in underlying demand. Shipments decreased 1.2%, primarily reflecting lower volumes in Europe, partially offset by a modest increase in the U.S. Adjusted EBITDA increased to $13.0 million in the second quarter, compared with $10.0 million in the prior quarter, primarily reflecting higher realized pricing, improved operating performance, and a more favorable sales mix, partially offset by higher manganese ore, energy, and transportation costs. Adjusted EBITDA margin increased to 12.1% in the second quarter, compared with 9.3% in the prior quarter.

​

Raw materials and energy consumption for production

​

Raw materials and energy consumption for production decreased to 51.5% of sales in the second quarter of 2026, compared with 64.3% in the prior quarter. This improvement was primarily driven by the recognition of a $59.9 million positive fair value adjustment related to long-term energy contracts, compared with a $5.5 million gain recognized in the first quarter of 2026. Excluding the impact of power purchase agreements, raw materials and energy consumption represented 67.3% of sales in the second quarter of 2026, compared with 65.9% in the prior quarter, primarily reflecting pressure on realized selling prices across most product categories and changes in the sales mix, while raw material and energy costs did not decline at the same pace, resulting in a narrowing of the price-cost spread.

​

Net Profit (Loss) Attributable to the Parent

​

In the second quarter of 2026, net profit attributable to the parent was $60.4 million, or $0.32 per diluted share, compared to a net loss attributable to the parent of $7.1 million, or $(0.04) per diluted share, in the prior quarter. The return to profitability primarily reflected a $59.9 million positive fair value adjustment related to long-term energy contracts, as well as improved operating performance, partially offset by higher selling expenses associated with increased sales volumes. The Company reported breakeven adjusted diluted earnings per share for the second quarter of 2026, compared with an adjusted diluted loss per share of $(0.07) in the prior quarter.

​

Adjusted EBITDA

​

Adjusted EBITDA increased to $13.1 million in the second quarter of 2026, compared with $3.3 million in the prior quarter. The sequential improvement reflected stronger shipment volumes and improved operating performance across the portfolio, supported by continued cost efficiency initiatives. These benefits were partially offset by higher selling and distribution costs.

| (1) | Total cash is comprised of restricted cash and cash and cash equivalents

(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 $93.2 million as of June 30, 2026, a decrease of $3.2 million from $96.4 million as of March 31, 2026. Adjusted gross debt decreased by $20.1 million to $130.9 million, resulting in net debt of $37.7 million as of June 30, 2026, representing a decrease of $16.9 million from the prior quarter.

​

During the second quarter, cash flows provided by operating activities were $37.0 million, and net cash used in investing activities was $13.6 million. Cash used in financing activities was $25.9 million as a result of lease payments of $3.9 million, dividend payments of $2.8 million, interest payments of $3.7 million, the principal repayments of other financing liabilities of $4.6 million, and financing facilities payments in South Africa, France and Spain totaling $11.4 million, partially offset by net cash proceeds from the sale of short-term commercial paper totaling $0.5 million.

​

Total working capital was $398.4 million as of June 30, 2026, a decrease of $32.8 million from $431.2 million at the end of the prior quarter. The decrease in our working capital balance during the quarter was primarily driven by a decrease of $12.8

​

million in inventories, $7.8 million in other receivables and an increase of $20.7 million in trade and other payables, partially offset by an $8.6 million increase in trade receivables.
​

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “The second quarter reflected a meaningful improvement in operating performance, with adjusted EBITDA increasing to $13.1 million, from $3.3 million in the first quarter, free cash flow of $20.4 million, and net debt declining to $37.7 million. Higher shipment volumes, disciplined working capital management, and continued cost control drove solid cash generation and further strengthened our balance sheet. With ample liquidity, reduced leverage, and a consistent dividend, we remain focused on maintaining financial flexibility while supporting the growth opportunities emerging from our core business and strategic critical materials initiatives.”

​

Capital Returns

​

During the second quarter, Ferroglobe did not repurchase shares and paid a quarterly cash dividend of $ 0.015 per share on June 30, 2026. Our next cash dividend of $0.015 per share will be paid on September 29, 2026, to shareholders of record as of September 22, 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 August 5, 2026 accompanying this presentation, which is incorporated by reference herein.
