HWM
Howmet Aerospace
Summary
What they do:
Manufacture precision-cast nickel superalloy components — turbine blades, vanes, and structural castings — for jet engines and gas turbines, sitting in Layer 21 as a critical supplier to GE Vernova, Siemens Energy, and other turbine OEMs whose gas turbines generate electricity for data centers.
Why they matter:
Gas turbines are the fastest path to new grid-scale power for data centers, and Howmet makes the parts that operate in the hottest, most stressed sections of every turbine. With 70%+ market share in superalloy castings, 18–24 month qualification cycles, and manufacturing complexity that takes 3–5 years to replicate, Howmet is as close to irreplaceable as any supplier in the AI power chain.
Recent performance:
Q4 2025 revenue $2.17B (+14.6% YoY). Gas turbine revenue up 32% in Q4, 25% for the full year. Record adjusted EBITDA $653M, margin 30.1%. 2026 guidance: ~10% revenue growth, adj EPS ~$4.45, EBITDA ~$2.76B. Stock at ~$256, market cap ~$103B.
Our Verdict
Consensus fortress industrial with the strongest moat in the AI power supply chain — 70%+ market share in superalloy castings with 18-24 month qualification barriers, but $103B market cap at 57x forward earnings prices in perfection.

Inside every gas turbine — the kind that GE Vernova builds to power data centers — there are hundreds of metal components operating in the hottest, most corrosive section of the machine. Turbine blades spin at 15,000+ RPM in gas streams exceeding 2,000°F. The metal must withstand temperatures that would melt conventional steel, resist oxidation, and maintain dimensional precision measured in thousandths of an inch. Howmet Aerospace manufactures these components.
The company operates four business segments. Engine Products (the largest) makes airfoils, structural castings, and rings for jet engines and gas turbines — this is the core AI-relevant business. Fastening Systems makes aerospace-grade fasteners. Engineered Structures makes titanium and aluminum structural components. Forged Wheels makes commercial vehicle wheels. Together, FY2025 revenue exceeded $8B, with Q4 reaching $2.17B (+14.6% YoY).
The gas turbine business is the story that matters for AI infrastructure. Gas turbine component revenue grew 32% in Q4 2025 and 25% for the full year, driven by surging electricity demand from data centers. GE Vernova, Siemens Energy, and Mitsubishi Power are all ramping turbine production to meet utility and hyperscaler demand. Howmet has secured new contracts with four major turbine customers, and the order backlog extends years. Every additional GW of gas turbine capacity ordered means millions of dollars in Howmet component orders — and gas turbine lead times of 4–5 years mean this demand is locked in.
Manufacturing is concentrated in foundries across the US, UK, Hungary, and Mexico. Superalloy casting is not a process you can outsource to a generic manufacturer — it requires specialized equipment (vacuum induction melting furnaces, directional solidification furnaces), decades of metallurgical process knowledge, and individual part qualifications with each OEM customer. Building a new facility from scratch takes 3–5 years and hundreds of millions of dollars. Capacity is fully utilized.
Supply Chain Dependencies
The Catch
Howmet's moat is one of the widest in the taxonomy, but the stock price already reflects it. At $103B market cap, investors are paying 57x forward earnings for a business growing 10%. The gas turbine tailwind is real, but it's now consensus — every data center power analyst has written about it. The risk is not that the business breaks (it won't) but that the growth rate disappoints relative to the price paid. A deceleration from 15% to 8% revenue growth would be operationally fine but could send the stock down 25–30% as the multiple compresses. Additionally, the long-term risk from alternative power technologies (nuclear, advanced renewables, potentially fusion) could gradually reduce gas turbine demand over a 15–20 year horizon — and at 57x earnings, you're implicitly betting on decades of dominance.
If They Win
If gas turbine demand for data center power grows 30%+ annually through 2030, if commercial aerospace production reaches 600+ narrowbody aircraft/year, if Howmet's supply constraint enables sustained pricing power, and if margins expand to 33%+ — Howmet becomes the TSMC of power generation components. Revenue compounds to $12B+, EBITDA to $4B+, and the company earns its way into the $150B+ market cap that the bull case requires. Every AI data center, every natural gas power plant, every jet engine contains hundreds of Howmet components that took decades to qualify and cannot be replaced. The moat doesn't just hold — it widens as demand outstrips capacity and qualification barriers become more valuable in a supply-constrained world.
