Overview
ASM International supplies wafer-processing deposition and thermal equipment plus aftermarket services. Q2 2026 revenue reached EUR1.003B: rounded category disclosures imply 79.2% equipment and 20.8% Spares & Services. The strongest demonstrated equipment advantages are accumulated materials/process know-how and layer-by-layer qualification: ASM reports greater than 55% ALD share, disclosed molybdenum-ALD wins at 1.4nm, and was selected by another DRAM customer for Epi in Q2. These advantages are strongest in ALD and Epi and are not assumed across every smaller equipment niche. The prior patent-count moat is removed because a large portfolio alone does not establish an IP choke point, and the service network is not double-counted beside the installed-base aftermarket moat.

Q2 2026 equipment revenue was EUR794.3M versus EUR208.7M for Spares & Services. Revenue shares are normalized to the rounded two-category subtotal so they sum exactly to 1. ASM does not disclose ALD, Epi, vertical-furnace, PECVD/CVD, or SiC-Epi revenue separately. The moat scores are best supported in ALD and Epi; smaller equipment niches are not assumed to have equal strength. The ALD >55% disclosure is retained as a sourced submarket fact rather than encoded as an overall equipment-market share.

Learning Curve Yield
Strength
Durability
Confidence
Evidence
ASM has accumulated materials, precursor, reactor, and process-integration know-how across successive device generations. Its company-reported greater-than-55% ALD share and current advanced-node wins support a strong advantage, but public disclosures do not provide customer yield comparisons that would justify a maximum score.
Learning Curve Yield moat: definition, examples, and stocks
Erosion risks
- Applied Materials, Tokyo Electron, Lam Research, and other rivals closing performance gaps
- Customers qualifying multiple suppliers to reduce dependence and increase price leverage
- Architecture or materials transitions moving critical deposition steps away from ASM strengths
Leading indicators
- ALD share and layer wins at new logic/foundry nodes
- ALD and Epi wins in DRAM and HBM process flows
- R&D intensity and new process or precursor introductions
Counterarguments
- The greater-than-55% ALD share is company-reported and does not establish the same advantage in every product line
- Large customers have the resources and incentive to qualify alternative tools

Durability
Confidence
Evidence
Deposition tools and recipes are qualified layer-by-layer for specific device nodes. Yield and integration risk make replacement difficult during a production cycle, but positions must be re-won as customers move to new architectures and nodes.
Design In Qualification moat: definition, examples, and stocks
Erosion risks
- Customers standardizing process flows to enable easier multi-sourcing
- Node delays or architecture shifts reducing the value of existing qualifications
- Competitors winning the next qualification cycle before high-volume production
Leading indicators
- New-node layer wins and tool-of-record positions
- Customer selections in DRAM, HBM, and advanced packaging
- Evaluation-tool placements and time to production qualification
Counterarguments
- Qualification protects a position for a process generation, not indefinitely
- Mature-node and standardized applications can support multiple qualified suppliers
Spares and services
Aftermarket spares, upgrades, and services for ASM wafer-processing equipment
Q2 2026 Spares & Services revenue was EUR208.7M. The revenue share is normalized against the rounded equipment-plus-services subtotal and therefore sums exactly with the equipment share.

Strength
Durability
Confidence
Evidence
Each installed ASM tool creates recurring demand for OEM spares, upgrades, process support, and outcome-based services. The installed base is the barrier; global field coverage is an enabling capability and is not scored again as a separate moat.
Installed Base Consumables moat: definition, examples, and stocks
Erosion risks
- Customers self-maintaining mature tools or qualifying third-party parts
- Fab-utilization declines reducing transactional spares demand
- Service-price concessions negotiated alongside future equipment awards
Leading indicators
- Spares & Services growth relative to equipment revenue and installed-base growth
- Outcome-based service adoption
- Fab utilization and third-party parts penetration
Counterarguments
- Some customers can self-service or use third parties for non-critical components
- The service network supports delivery but is not independently shown to be harder to replicate than peers' networks
Evidence
leading >55% market share in ALD
This is a company-reported lower bound for the ALD submarket, not an overall equipment-market share estimate.
world-class expertise in precursor innovation and atomistic process technology
Management directly identifies the materials and process capabilities supporting leading-edge logic and HBM applications.
recent wins in our Mo ALD offerings at the 1.4nm node
A specific next-node application win is direct evidence that qualification occurs by material layer and process generation.
selected by another DRAM customer for our Epi solution
A new customer selection supports the existence of product-specific evaluation and qualification in Epi.
single-wafer CVD offerings with some innovative solutions that are being qualified in memory and advanced packaging
Current qualification activity extends beyond ALD and Epi, although commercial scale is not yet disclosed.
