A capacity ramp with thin room for error
- Ichor is tied mainly to wafer fab equipment, especially etch, deposition, and EUV tools.
- Management noted the current footprint can support up to $3 billion in annual revenue with modest investments.
- The company substantially completed its geographic footprint restructuring in the second quarter of 2026.
- Execution risk remains as external flow control shortages pushed some second quarter revenue into the third quarter.
- Two customers, Lam Research and Applied Materials, made up 76% of 2025 sales.
- The company expects gross margin to improve by 100 basis points in both the third and fourth quarters of 2026.
Demand is ahead of capacity
The bull case starts with a fast demand ramp. Management noted that second half revenue volumes are expected to be at least 25% higher than the first half. The company substantially completed its geographic footprint restructuring in the second quarter of 2026, setting a path to 20% gross margins. With modest investments, the current global footprint can support up to $3 billion in annual revenue.
The bigger prize is mix. Ichor has long assembled important subsystems for other tool makers. Now it wants more of the parts inside those systems to be Ichor branded. The target is to exit 2026 delivering 35% Ichor branded content within the systems it builds, up from 25% at the end of 2025.
The bear case centers on supply chain issues and end market drags. External flow control shortages pushed some revenue from the second quarter into the third quarter. Additionally, EUV lithography orders are expected to stay soft through the third quarter as customers work down inventory. Silicon carbide demand also remains structurally weak.
The stock needs proof over promises. If gross margin expands in the second half of 2026 and supply constraints clear, the thesis gets stronger. If customer demand rises but Ichor cannot secure external parts to ship finished systems, the ramp could stall.
The plumbing inside chip tools
Ichor makes fluid delivery subsystems. In plain English, these are the gas and chemical control systems inside machines that make chips. They must move exact amounts of gases and liquids during steps like etch, deposition, cleaning, and polishing.
The customers are big semiconductor equipment makers. They outsource work to suppliers like Ichor because the parts are complex, must be extremely clean, and have to fit tightly into new tool designs. Ichor makes money when those customers build more tools and order more subsystems and components.
The weakness in the model is power. A few customers drive most of sales, and those customers can push on price, quality, delivery time, and volume. The 2025 Form 10-K reported Lam Research and Applied Materials together accounted for 76% of total sales.
Management is trying to improve that model by adding more proprietary parts, such as valves, fittings, substrates, and seals. If those parts qualify at customers and ship in volume, Ichor can keep more value inside each system. The company believes its newly aligned operations in Mexico and Malaysia will boost margins regardless of the proprietary mix.
From systems to owned parts
Gas delivery systems
These systems deliver and control specialty gases in semiconductor tools. They are core to Ichor's long customer relationships in etch and deposition.
Chemical delivery systems
These systems blend and dispense liquid chemicals used in chip manufacturing steps such as cleaning, electroplating, and polishing.
Precision machining
Ichor machines high-precision parts used in its own systems and customer products. The commercial space segment recently received a new official qualification for a growing part family.
Weldments and specialty joining
The company provides weldments, brazing, and surface treatment work. Management noted this segment is beginning to recover after a period of contraction.
Valves and flow control products
Valves are a key part of the proprietary content plan. Ichor achieved full customer qualification to manufacture its valve line in Mexico early in 2026.
Substrates, fittings, and seals
These parts can raise Ichor branded content inside the systems it builds. All manufacturing steps for the substrate line are now performed within Mexico.
A customer-heavy mix
The 2025 Form 10-K notes Ichor derived over 90% of sales from semiconductor capital equipment. The shares below use 2025 customer concentration, with Lam Research and Applied Materials combined.
What could break the ramp
Supply chain constraints
High impact · High oddsExternal flow control supply shortages pushed some second quarter 2026 revenue into the third quarter. If outside parts remain scarce, Ichor cannot fully capitalize on surging customer demand.
Two-customer dependence
High impact · High oddsLam Research and Applied Materials made up 76% of 2025 sales. If either customer cuts orders, delays a tool program, or forces lower pricing, Ichor has limited room to offset the hit quickly.
Margin ramp misses
High impact · Medium oddsIchor expects gross margin to hit 20% as Mexico and Malaysia operations ramp. The risk is that outside supply costs, training, labor, or transfer delays last longer than planned.
USMCA and tariff change
High impact · Medium oddsIchor has expanded its Mexico footprint, and the 2025 Form 10-K says those operations benefit from USMCA exemptions. The scheduled July 2026 USMCA joint review could alter those benefits.
EUV inventory drag
Medium impact · High oddsThe lithography, or EUV, part of demand remains weak while customers digest inventory through the third quarter of 2026. Management expects an order pickup in the fourth quarter, but that timing is not guaranteed.
In one breath
What does Ichor Holdings actually make?
Ichor makes gas and chemical delivery systems used inside semiconductor manufacturing tools. These systems help move exact amounts of gases and liquids during chipmaking steps.
Why does proprietary content matter for Ichor?
Proprietary content means more Ichor branded parts inside each system it builds. If customers qualify those parts, Ichor can capture more value instead of only assembling parts from others.
Why is customer concentration such a big issue?
Ichor sells to a small group of very large chip equipment makers. In 2025, Lam Research and Applied Materials together made up 76% of sales, so one customer change can move the whole company.
What is the main 2026 catalyst for Ichor?
The key catalyst is margin expansion in the second half of 2026 as Mexico and Malaysia ramp. Investors will also watch proprietary component beta units, EUV orders, and the recent USMCA review.
