ASML wins TSMC, Samsung commitments for next-gen EUV

The commitments validate ASML's multi-year bet on high-NA EUV, effectively locking in its roadmap with the two largest foundry customers. This reduces near-term demand uncertainty for its most advanced systems, though the disclosed lack of financial terms leaves margin and volume visibility unclear. The significance extends beyond ASML: it signals that leading-edge chipmakers are aligning on a specific lithography path, which could shape capital expenditure cycles across the semiconductor supply chain. Whether rival technologies or cost pressures alter these commitments later is the open question.
