Ferroglobe PLC (GSM) | The Buildout — AI Infrastructure
The Verdict
Ferroglobe is a Western processor of silicon metal, ferrosilicon, and manganese alloys—intermediate materials for steel, aluminum, chemicals, solar, and semiconductor supply lines. It is positioning itself as a domestic processing answer for critical materials by using existing electric-arc furnace infrastructure. Its AI-infrastructure connection is indirect: silicon metal feeds polysilicon for semiconductors and solar, and its Coreshell stake reaches silicon-anode batteries for robotics and defense.

What We Like
- Trade protection is converting into volumes: Q1 2026 shipments rose 7% sequentially to 177,000 tons, and silicon-based alloys volume hit a near five-year high.
- Manganese safeguards are working: the EU manganese alloy index is up about 25% after November 2025 safeguards and 10% in Q2 2026.
- Critical-materials pipeline now names ferromolybdenum, magnesium, antimony, silver, gallium, and vanadium/chromium alloys, with ferromolybdenum industrial-scale test production completed.
- Venezuela restart path advanced: a U.S. permit application was filed late June 2026 for 120,000 tons/year of flexible capacity across four furnaces, with a decision expected before end Q3.
What We’re Watching
- European silicon metal remains excluded from safeguards and adjusted-EBITDA-negative; Q2 2026 silicon metal adjusted EBITDA was -$2.7M.
- EU ferrosilicon safeguard effectiveness review arrives November 2026; the EU index was down 14% year-to-date despite safeguards.
- Critical-materials economics are undisclosed: market sizes are given, but margins, capex payback, and government support amounts are not quantified.
- Venezuela restart capex, energy cost, and raw-material logistics remain unresolved while the permit decision is pending.
The thesis is strengthening on operational execution: management has delivered furnace conversions, the Coreshell term sheet, U.S. trade-case wins, and ferromolybdenum test production. But the financial proof remains thin—Q1 FY2026 gross margin was 12.5% and reported EBITDA was -$11.6M, while the weakest segment, silicon metal, stays EBITDA-negative. The open question is whether EU silicon metal protection and first critical-materials sales can convert volume momentum into durable margin recovery.
Earnings
Ferroglobe reported Q1 FY2026 revenue of $347.7M, up 5.6% sequentially, with gross margin of 12.5%. Reported EBITDA was -$11.6M, and management's adjusted EBITDA was $3M on 177,000 tons shipped.

The prices that we see today, particularly in Europe, particularly on silicon metal and ferrosilicon are simply unacceptable for everybody.— Marco Levi, Chief Executive Officer, May 6, 2026
Management tone: Management was frustrated on pricing but optimistic on volumes on the Q1 call, then became more specific on strategic projects by the Q2 call while staying blunt about weak European pricing. The CEO openly said EU safeguards are not having their desired impact on the ferrosilicon market.
Management Guidance
No formal numeric guidance update was provided on the latest quarter call. Management expects stable volumes for the balance of 2026.
Trajectory
Revenue has moved from $312M in Q3 FY2025 to $329M in Q4 FY2025 and $347.7M in Q1 FY2026, two consecutive sequential increases. EBITDA improved from -$120.7M in Q4 FY2025 to -$11.6M in Q1 FY2026, but remains negative. The computed signals label revenue trajectory as accelerating while operating and EBITDA margins are still compressing.
The Model
The model projects FY+1 revenue of $1,575M and EBITDA of $76M, a 4.8% margin, rising to FY+2 revenue of $1,700M and EBITDA of $144M, an 8.5% margin. The near-term projection rests on volume recovery and trade-protected pricing, while FY+2 assumes critical-materials commercialization and continued margin expansion.

Projections are the median of 5 independent model runs. The model’s revenue sits 7.7% below analyst consensus.

What Could Go Right — and Wrong
- EU announces and pursues a silicon metal anti-dumping investigation against China and Angola, removing the European price overhang.
- Silicon metal reaches adjusted-EBITDA breakeven in H2 2026 as priced demand improves after U.S. trade-case finalization.
- Venezuela permit is granted before the end of Q3 2026 and the 120,000-ton low-cost restart proceeds.
- Initial commercial critical-materials sales occur before year-end 2026, starting with ferromolybdenum and other alloys.
- November 2026 EU ferrosilicon safeguard review closes the silicon-substitution loophole and restores alloy pricing.
- EU silicon metal investigation is delayed or weak, leaving the segment EBITDA-negative and exposed to Chinese and Angolan imports.
- Ferrosilicon pricing remains blocked; the EU index stays down 14% YTD because silicon metal substitutes for ferrosilicon.
- Critical materials stay pilot-stage; no commercial sales or government support materialize.
- Venezuela permit is denied or delayed, leaving 120,000 tons of capacity stranded.
- Free cash flow remains dependent on working-capital timing; Q2's positive $20M free cash flow was driven by a $28M working-capital release.
Looking Ahead
The next 12 months turn on three visible gates: a U.S. permit decision on Venezuela before the end of Q3 2026, a potential EU Commission silicon metal investigation announcement, and the November 2026 EU ferrosilicon safeguard effectiveness review. Management also targets initial commercial critical-materials activity before year-end 2026 and additional industrial-scale tests later this year.
- Before end Q3 2026Venezuela permit decision — Tests whether the 120,000-ton flexible restart path is viable.
- November 2026EU ferrosilicon safeguard review — Key checkpoint for whether EU alloy pricing can recover from -14% YTD.
- Later 2026Additional critical-alloy tests — Shows whether ferromolybdenum test production can be repeated across other materials.
- Before year-end 2026Initial critical-materials commercial activity — Would convert strategic tests into first revenue and de-risk the platform.
- No date disclosedEU silicon metal investigation announcement — Management expects the EU Commission to publicly announce a China/Angola case.
- End-2027 to 2028Coreshell OEM qualification — Estimated window for pilot battery qualification; drives later silicon metal offtake.

The Company
Ferroglobe is a Western processor of silicon metal, ferrosilicon, and manganese-based alloys. Its products feed aluminum smelters, silicone chemical producers, steelmakers, foundries, polysilicon producers, and semiconductor/electronics applications. The 20-F describes the company as one of the world's largest producers of silicon metal, silicon-based alloys, and manganese-based alloys, with quartz mining, low-ash metallurgical coal mining, and hydroelectric power interests.
Operations span North America, Europe, South Africa, China, and Argentina across its reportable segments. The company uses submerged-arc electric furnaces and can switch some capacity between silicon metal and ferrosilicon; three furnaces were converted to ferrosilicon in 2026. It holds 51% of Bécancour, Canada, and controls assets including Selma, Alabama, idle since December 2023, Polokwane, South Africa, idled for the foreseeable future, and four flexible furnaces in Venezuela.
