1. Business Role
Fouquet sits between a technology roadmap and a manufacturing commitment. ASML can promise a future scanner capability, but a chipmaker must decide when to design a process around it, prepare a factory and place equipment orders. A missed interface between those plans can make a technically impressive machine commercially late.
His earlier EUV and business responsibilities are relevant because the CEO must connect those interfaces rather than optimize one in isolation. Running ASML involves customer qualification, supplier investment, factory output and support of tools already earning money in customer fabs. These are organizational responsibilities, not evidence that the CEO personally designs each system. [S23]
2. The Business He Inherited
Fouquet inherited a company with a strong production EUV position, a large DUV business and a service network embedded in semiconductor factories. Its commercial relationships were established before he became CEO. Peter Wennink and Martin van den Brink handed over a business whose next challenge was extending those assets without disrupting them. [S24][S46]
High-NA was at a different maturity level from the NXE installed base. Customers needed evidence of imaging, throughput and process readiness before broad insertion. Export restrictions also made market access conditional on licenses rather than customer willingness alone.
The starting point therefore combined market strength with concentrated operational exposure. A few chipmakers could move large amounts of demand; a few specialized suppliers could constrain output. Increasing sales required coordination across that network, not simply hiring a larger sales force.
3. Business Thesis
More output is valuable only when it is qualified output
In the October 2026 results statement, Fouquet linked stronger customer forecasts to plans for additional capacity and emphasized productivity upgrades as another source of wafer output. This is a publicly documented operating priority, not a forecast that every customer order will become revenue. [S4]
The commercial logic is that a customer needs working wafer capacity at a particular time. An upgrade that lifts output on an accepted scanner can matter sooner than an additional machine waiting for installation.
A new generation must improve the customer's process
High-NA's purpose is not simply to sell a more advanced scanner. It is to make selected patterning flows less complex. Whether that creates value depends on the complete manufacturing sequence, including masks, resist, inspection and the process steps replaced. Customer insertion must establish that benefit rather than infer it from optical resolution alone. [S8][S9]
4. Strategic Bets
Expand capacity before all uncertainty disappears
By Q3 2026, management said the currently planned supply for 2027 and 2028 would not fully meet customer demand forecasts. It was investigating additional 2028 expansion. That statement records management's view at the time; it does not make future demand certain. [S4]
The mechanism is long-lead preparation: suppliers, manufacturing space, modules and installation resources must be available before a customer starts a new node. The risk is that customers change their spending plans after ASML has committed resources. Fouquet's leadership can be evaluated on that balance, not on the headline size of an order book alone.
Move High-NA from equipment delivery to production evidence
ASML and Intel reported production use on selected layers for a subset of Panther Lake processors in 2026. Their later million-wafer statement combined certification, development and production activity; it was not a million-wafer tally of commercial output. [S8][S9]
This is a leadership-level commercialization program. Engineers, Intel and the wider ecosystem produced the qualification results. Fouquet's role is overseeing the business conditions in which the program reaches customers, not claiming personal authorship of those results.
Invest in software and engineering productivity
ASML's 2025 Mistral AI partnership included a €1.3 billion investment. It creates an opportunity to apply AI to engineering and operations, but an investment announcement is not proof of realized scanner productivity or a separate software profit stream. [S36]
The bet extends the company's problem-solving capacity. Its commercial result must be assessed through deployed tools and demonstrable improvements, not through a general association with AI.
5. How Those Bets Changed the Business
The most immediate change is operating scale rather than a complete change in customer identity. ASML still sells to chip manufacturers. Its task is to supply more qualified patterning capacity while increasing the contribution of upgrades to that output.
Product scope is also widening. High-NA adds another production option; advanced packaging applies some existing precision capabilities outside the most advanced transistor layers. Neither makes established Low-NA and DUV tools irrelevant. [S12][S52]
The effect on the business is a more demanding portfolio: different generations must improve together. This raises the importance of installation, customer support and supplier readiness alongside research.
6. Resource Allocation
Capacity expansion consumes more than factory capital. It also requires working inventory, supplier commitments, training and field-engineering coverage. Those resources must be sequenced: a completed scanner cannot create capacity if its customer site or support team is unready.
Research must meanwhile support current-product improvements and future technologies. Moving all engineering effort to High-NA would damage the tools on which customers currently depend. Treating the installed base only as maintenance would miss opportunities to release additional wafer output. ASML's disclosed upgrade demand shows why that allocation matters commercially. [S4][S51]
7. Business Model: Before vs. After
| Dimension | At the 2024 handover | Position by October 2026 |
|---|---|---|
| Core buyer | Semiconductor manufacturers | Same buyer structure; stronger demand forecasts |
| EUV portfolio | Established NXE; early EXE deployment | NXE remains important; specific EXE production evidence |
| Installed base | Service and field options | Greater disclosed demand for productivity upgrades |
| Main execution challenge | Technology transition and customer timing | Additional qualified capacity across a constrained network |
| Uncertainty | Adoption, cycles and regulation | Those uncertainties remain despite stronger demand |
This is an interim comparison. Fouquet's tenure is still in progress, so a final legacy cannot be assigned.
8. What Worked / What Remains Unproven
Customer-specific High-NA production evidence and the Q3 2026 upgrade contribution are observable developments. They are stronger evidence than an undated claim that the entire platform is ready everywhere. [S4][S8]
Broader High-NA adoption, sustained capacity execution and the operational benefits of AI collaboration remain separate tests. Supplier bottlenecks, customer spending changes and licensing decisions can constrain outcomes even when technology performs as intended.
9. Business Legacy
Fouquet's eventual legacy will depend on whether ASML can scale without sacrificing customer trust or the next roadmap. The structure he is managing is already institutional: specialist suppliers, customer process knowledge, engineers and a worldwide support organization.
The meaningful outcome would be a stronger ability to deliver successive generations reliably. That would be an organizational achievement under his leadership, not the work of one executive alone.
Career Timeline

Serves as Executive Vice President EUV during an important commercialization period. [S23]
2022–2024 — Chief Business Officer

Common Misconceptions
Fouquet created ASML's EUV business
EUV development and customer adoption began long before his CEO appointment. His responsibility is a subsequent stage of scaling and technology transition.
A demand forecast is a guaranteed shipment
Customers can change node timing, factory plans and investment. Management's capacity statements must retain their date and conditions.
Evidence
- Official governance records establish his roles and succession. [S23][S46]
- The Q3 2026 release records management's capacity and upgrade statements. [S4]
- Customer-specific releases establish the scope of High-NA progress. [S8][S9]
- The Mistral announcement establishes the investment, not a realized operating return. [S36]
