Didier Scemama's questions to ASML HOLDING (ASML) leadership

Didier Scemama's questions to ASML HOLDING (ASML) leadership • Q3 2025

Question

Didier Scemama questioned ASML's perspective on recent HBM capacity announcements from SK Hynix and Samsung, which imply a significant increase in EUV tool demand for HBM, and whether ASML has sufficient EUV low NA capacity by 2030 to meet such potential demand. He also asked about the portion of ASML's current backlog that extends beyond 2026, potentially explaining hesitation for strong 2026 growth.

Answer

CEO Christophe Fouquet expressed caution regarding translating large announcements into concrete capacity needs but highlighted the importance of a broadening customer base to avoid supply limitations. He confirmed ASML has been preparing for growth and has no concerns about meeting demand. CFO Roger Dassen stated that a 'reasonable number' of the current backlog pertains to beyond 2026, including a 'pretty strong' High NA contingent, which makes precise 2026 projections difficult.

Didier Scemama's questions to ASML HOLDING (ASML) leadership • Q2 2025

Question

Didier Scemama of Bank of America inquired why the potential removal of an AI chip export ban to China would be a positive for ASML and asked if the strength in DUV demand from China was driven by customers pulling in orders ahead of further restrictions. He also asked for color on High-NA bookings.

Answer

EVP & CFO Roger Dassen explained that lifting restrictions is a positive for the entire semiconductor ecosystem's global reach, which benefits ASML indirectly. He stated that China's DUV demand remains strong and is aligning with its share of the backlog, not necessarily indicating a new pull-in dynamic. He also confirmed the quarter's EUV bookings included High-NA orders but could not provide specifics at the customers' request.

Didier Scemama's questions to ASML HOLDING (ASML) leadership • Q1 2025

Question

Sought confirmation on calculated Low-NA EUV ASPs and gross margins, and asked for reasons behind the increased 2025 revenue forecast for China and the outlook for China's Installed Base Management (IBM) revenue.

Answer

The calculated ASP of ~€227M is correct but high; a blended rate of ~€220M is better for modeling. Low-NA gross margin is above the corporate average, but specifics are not disclosed. The China revenue forecast was raised to over 25% due to resilient and stronger-than-expected demand for mainstream DUV systems.

Didier Scemama's questions to LOGITECH INTERNATIONAL (LOGI) leadership

Didier Scemama's questions to LOGITECH INTERNATIONAL (LOGI) leadership • Q1 2026

Question

Didier Scemama from Bank of America inquired about the consumer reaction to recent price increases and the sustainability of the strong growth observed in the Video Collaboration (VC) business.

Answer

CEO Hanneke Faber explained it was too early to gauge consumer reaction to pricing, as increases were only fully implemented at the end of the quarter. She noted the price negotiations temporarily affected Americas' net sales but are now complete. Regarding VC, she acknowledged the 13% growth was strong but may have been slightly inflated by some customer pull-in ahead of tariffs and inventory replenishment in the EU, though underlying demand remains robust.

Question

Didier Scemama asked if the positive inventory effect on Q1 gross margins would extend into Q2, questioned the margin phasing for the rest of the year, and sought confirmation that the 90-day tariff pause includes PC peripherals.

Both he and CEO Hanneke Faber stated it was too premature to comment on the margin outlook for subsequent quarters. Hanneke Faber also confirmed their Q1 guidance already incorporates the current tariff landscape, including the 90-day pause.

Didier Scemama's questions to INFINEON TECHNOLOGIES (IFNNY) leadership

Didier Scemama's questions to INFINEON TECHNOLOGIES (IFNNY) leadership • Q2 2025

Question

Didier Scemama asked about the mechanics of the revised full-year margin guidance, the assumptions behind the tariff-induced revenue reduction, and the outlook for the AI business.

Answer

CFO Sven Schneider explained the margin revision was due to volume reduction from the tariff guesstimate, higher underutilization charges, a significant negative currency effect translating to a €150-170 million segment result headwind, and some pricing pressure in industrial components. He clarified the tariff impact is a ~€400 million "guesstimate" and not based on order book changes. CMO Andreas Urschitz confirmed the €600 million AI revenue target for the current year and €1 billion for the next.
