Rhea-AI Filing Summary

Ferroglobe PLC reported a smaller net loss but weaker profitability in Q1 2026. Sales reached $347.7 million, up 5.6% from Q4 2025 and 13.2% year over year, driven mainly by higher volumes in silicon-based and manganese-based alloys.

Net loss attributable to the parent narrowed sharply to $7.1 million (basic and diluted loss per share $0.04) from $81.0 million in the prior quarter, largely because Q4 2025 included sizable fair value losses on long-term energy contracts, impairments and extra depreciation. However, adjusted EBITDA fell to $3.3 million from $14.6 million as higher logistics and raw material costs outpaced pricing.

By segment, silicon metal revenue declined to $84.1 million with negative adjusted EBITDA of $2.3 million, while silicon-based alloys and manganese-based alloys generated revenues of $122.3 million and $107.2 million, respectively, with positive but lower margins. Total cash was $96.4 million and net debt $54.6 million as of March 31, 2026, after negative operating cash flow and higher working capital.

Insights

Revenue grew and losses shrank, but margins, cash flow and silicon metal remain weak.

Ferroglobe lifted Q1 2026 sales to $347.7 million, with strong shipment growth in silicon-based and manganese-based alloys. The headline loss improved to $7.1 million as prior-quarter energy contract losses, impairments and extra depreciation rolled off.

Underlying profitability deteriorated, with adjusted EBITDA dropping to $3.3 million from $14.6 million. Silicon metal swung to an adjusted EBITDA loss of $2.3 million, while silicon-based alloy margins compressed despite higher volumes. Management cited higher logistics, manganese ore and coal costs and competitive pricing, especially in silicon metal.

Liquidity remains adequate but trended weaker. Total cash declined to $96.4 million and net debt increased to $54.6 million, with negative operating cash flow of $5.6 million and free cash flow of $16.4 million outflow. Subsequent quarters will show whether expected pricing improvements and cost control can restore margins and stabilize cash generation.

Sales $347.7 million Q1 2026 consolidated revenue, up 5.6% Q/Q and 13.2% Y/Y
Net loss attributable to parent $7.1 million Q1 2026, versus $81.0 million loss in Q4 2025
Adjusted EBITDA $3.3 million Q1 2026, down from $14.6 million in Q4 2025
Silicon metal revenue $84.1 million Q1 2026 segment revenue, down 12.9% from prior quarter
Silicon-based alloys revenue $122.3 million Q1 2026, up 18.1% Q/Q with 18.3% shipment growth
Manganese-based alloys revenue $107.2 million Q1 2026, up 15.7% Q/Q; adjusted EBITDA $10.0 million
Total cash $96.4 million Balance as of March 31, 2026, down from $123.0 million at year-end 2025
Net debt $54.6 million As of March 31, 2026, up $24.8 million from prior quarter
Adjusted EBITDA financial
"Adjusted EBITDA declined to $3.3 million in the first quarter of 2026"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
free cash flow financial
"Free cash flow 2 | $ | (16.4) | $ | (18.5) |"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
fair value loss financial
"absence of the $40.2 million fair value loss related to long term energy contracts"
power purchase agreements financial
"Excluding the impact of power purchase agreements, raw materials and energy consumption"
A power purchase agreement is a long-term contract in which a buyer agrees to purchase electricity from a specific generator at a set price and schedule, much like a multi-year subscription for energy. For investors, these contracts matter because they lock in predictable revenue and price terms, reducing exposure to volatile wholesale power markets and making project cash flows and financing risks easier to evaluate.
net debt financial
"resulting in net debt of $54.6 million as of March 31, 2026"
Net debt is the total amount a company owes after subtracting the cash and assets it has that can be used to pay off that debt. It shows how much debt is truly a burden, helping investors understand if a company is financially healthy or heavily borrowed. Think of it like calculating how much money you owe after using your savings to pay part of it.

Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “We delivered a strong increase in first quarter ferroalloy shipment volumes in both the EU and the U.S, driven primarily by recently enacted trade measures. While volumes improved, pricing did not keep pace with higher costs, particularly in logistics and raw materials, resulting in margin compression. We view these cost pressures as temporary and expect pricing conditions to improve in the second half of the year.  

“We see significant opportunities to diversify both our footprint and product mix, directly supporting our long-term strategic growth strategy. In Venezuela, we own four furnaces with more than 100,000 tons of incremental capacity, with the flexibility to produce across all our core product segments. Beyond this, we are actively evaluating which critical materials are most economically viable to produce, leveraging our established Western footprint and past production experience. The newly signed U.S. and EU strategic partnership on critical materials signals a structural shift, strengthening our position as markets increasingly prioritize secure, domestic supply chains for strategic materials,” concluded Dr. Levi.

Consolidated Sales

In the first quarter of 2026, Ferroglobe reported sales of $347.7 million, a 5.6% increase from the prior quarter and a 13.2% increase from the comparable prior-year period. This improvement was mainly driven by higher sales volumes of silicon-based alloys and manganese-based alloys, as well as a higher average selling price for manganese-based alloys, partially offset by lower volumes and average selling price for silicon metals. Silicon-based alloys prices remained stable during the quarter. Sales of silicon metal decreased by $12.4 million from the prior quarter, while silicon-based alloys and manganese-based alloys increased by $18.7 million and $14.5 million, respectively, compared with the prior quarter.

Silicon metal revenue in the first quarter was $84.1 million, a decrease of 12.9% from the prior quarter. The average selling price decreased 6.9%, driven by lower pricing in the U.S. and Europe amid a more competitive market environment and cautious customer purchasing in key end-markets, particularly in Europe, partially offset by a slight increase in South Africa. Shipments decreased 6.4%, primarily reflecting lower volumes in EMEA, partially offset by higher volumes in the U.S. Adjusted EBITDA decreased to $(2.3) million in the first quarter, compared with $0.9 million in the prior quarter, reflecting lower realized pricing and shipments, partially offset by strong cost performance in Canada. Adjusted EBITDA margin decreased to (2.7%) in the first quarter from 0.9% in the prior quarter.

Silicon-based alloy revenue in the first quarter was $122.3 million, an increase of 18.1% from the prior quarter. The average selling price was stable, as higher realizations in Europe were largely offset by softer pricing in the U.S. and South Africa, where market conditions remained competitive. Shipments increased 18.3%, reflecting a broad-based improvement across regions, with the most significant increase in the U.S., supported by improved demand and customer restocking in steel and foundry applications. Adjusted EBITDA decreased to $6.8 million in the first quarter of 2026, down from $15.5 million in the prior quarter, primarily reflecting higher production costs, which more than offset the benefit from higher volumes. Adjusted EBITDA margin decreased to 5.6% in the first quarter, compared with 15.0% in the prior quarter.

Manganese-based alloy revenue in the first quarter was $107.2 million, an increase of 15.7% from the prior quarter. The average selling price increased 9.0%, driven by higher pricing in Europe, partially offset by a slight decrease in the U.S. Shipments increased 6.1%, reflecting solid volume growth in Europe as steel-related demand for domestic manganese alloys improved. Adjusted EBITDA increased to $10.0 million in the first quarter, compared with $8.7 million in the prior quarter,


supported by higher volumes and prices, offset by higher manganese ore, energy, and transportation costs. Adjusted EBITDA margin was 9.3%, broadly in line with 9.4% in the prior quarter.

Raw materials and energy consumption for production

Raw materials and energy consumption for production decreased to 64.3% of sales in the first quarter of 2026, compared with 79.4% in the prior quarter. This improvement was primarily driven by the absence of the $40.2 million fair value loss related to long term energy contracts recognized in the fourth quarter of 2025, as well as the recognition of a positive fair value adjustment of $5.5 million in the first quarter of 2026. Improved production levels and better fixed cost absorption also contributed to the sequential improvement. Excluding the impact of power purchase agreements, raw materials and energy consumption represented 65.9% of revenue in the first quarter of 2026, compared with 67.2% in the prior quarter.

Net (Loss) Attributable to the Parent

In the first quarter of 2026, net loss attributable to the parent was $7.1 million, or $(0.04) per diluted share, compared to a net loss attributable to the parent of $81.0 million, or $(0.43) per diluted share, in the prior quarter. The quarter over quarter improvement was primarily driven by the absence of the $40.2 million negative fair value remeasurement impacts related to long-term energy contracts recorded in the fourth quarter, as well as the absence of an impairment charge of $17.7 million and additional depreciation of $12.6 million recognized in the prior quarter. Results in the first quarter of 2026 also benefited from improved operating leverage, partially offset by higher selling-related expenses associated with increased sales volumes. The Company reported adjusted diluted earnings per share of $(0.07) for the first quarter of 2026, compared with $(0.06) in the prior quarter.


Adjusted EBITDA

Adjusted EBITDA declined to $3.3 million in the first quarter of 2026, compared to $14.6 million for the prior quarter. The prior quarter benefited from a one time positive impact of approximately $12 million related to the modification of a lease liability agreement. During the first quarter of 2026, operating performance improved, supported by stronger volumes and continued cost efficiency initiatives, partially offset by higher selling and distribution costs.

(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 $96.4 million as of March 31, 2026, a decrease of $26.6 million from $123.0 million as of December 31, 2025. Adjusted gross debt decreased by $1.8 million to $151.0 million, resulting in net debt of $54.6 million as of March 31, 2026. This represents an increase of $24.8 million from the prior quarter.

During the first quarter, cash flows used in operating activities were $5.6 million, and net cash used in investing activities was $17.1 million. Cash used in financing activities was $3.3 million as a result of lease payments of $3.9 million, dividend payments of $2.8 million, interest payments of $2.4 million, and the principal repayments of other financing liabilities of $0.7 million, partially offset proceeds from financing facilities in South Africa, France and Spain totaling $3.4 million, net cash proceeds from the sale of short-term commercial paper totaling $3.1 million.

Total working capital was $431.2 million as of March 31, 2026, an increase of $3.7 million from $427.5 million at the end of the prior quarter. The increase in our working capital balance during the quarter was primarily driven by increases of


$28.1 million in inventories, $20.9 million in trade receivables, and $16.8 million in other receivables, partially offset by a $62.1 million increase in trade and other payables.

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “We delivered solid sales in the first quarter, with revenue increasing almost 6%, driven by higher volumes in our silicon-based alloy and manganese-based alloy segments.  However, lower silicon metal prices and margin compression in silicon-based alloys impacted profitability, resulting in adjusted EBITDA of $3.3 million, compared with $14.6 million in the fourth quarter. The conflict in Iran created a challenging operating environment during the quarter, with higher transportation, logistics, and raw material costs, primarily manganese ore and coal, without a corresponding improvement in our realized prices. While these pressures affected adjusted EBITDA and resulted in negative free cash flow, we maintained disciplined capital expenditure management. Importantly, we ended the quarter with a solid liquidity position, including $96.4 million of total cash and a manageable net debt level of $54.6 million.”

Capital Returns

During the first quarter, Ferroglobe repurchased 5,140 shares at an average price of $3.90 per share and paid a quarterly cash dividend of $ 0.015 per share on March 30, 2026. Our next cash dividend of $0.015 per share will be paid on June 29, 2026, to shareholders of record as of June 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 May 5, 2026 accompanying this presentation, which is incorporated by reference herein.

FAQ

How did Ferroglobe (GSM) perform financially in Q1 2026?
