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 Adj.EBITDA Margin		(2.5)%		(2.7)%			5.0%			(2.6)%		(3.8)%

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 Alloys


($,000)	Q2 2026		Q1 2026		% Q/Q	Q2 2025		% Y/Y	YTD 2026		YTD 2025		% Y/Y
Shipments in metric tons:		62,915		60,674	3.7%		53,048	18.6%		123,589		95,913	28.9%
Average selling price ($/MT):		1,986		2,016	(1.5)%		2,105	(5.7)%		2,001		2,112	(5.3)%

Silicon-based Alloys Adj.EBITDA Margin		11.6%		5.6%			6.4%			8.6%		4.7%

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 Alloys



($,000)	Q2 2026		Q1 2026		% Q/Q	Q2 2025		% Y/Y	YTD 2026		YTD 2025		% Y/Y

Average selling price ($/MT):		1,270		1,250	1.6%		1,204	5.5%		1,260		1,162	8.4%

Manganese-based Alloys Revenue		107,635		107,179	0.4%		106,178	1.4%		214,824		180,595	19.0%
Manganese-based Alloys Adj.EBITDA		13,014		10,014	30.0%		16,794	(22.5)%		23,028		11,220	105.2%
Manganese-based Alloys Adj.EBITDA Margin		12.1%		9.3%			15.8%			10.7%		6.2%

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.

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.
