ASML's Q1 2026 release from Veldhoven landed with: net sales of €8.8bn, net income of €2.8bn, gross margin of 53.0 per cent, and earnings of €7.15 per share. China accounted for 19 per cent of system sales in the quarter, down from 36 per cent in Q4 2025, a revenue drop of roughly €1.8bn driven by tightened US Deep Ultraviolet lithography export controls. ASML raised its full-year 2026 guidance to €36-40bn. The stock fell 6 per cent on results day, and a bipartisan group of US lawmakers proposed a bill within days of the report to tighten DUV sales to Chinese chipmakers further.
Chief Executive Christophe Fouquet said the 2026 guidance "accommodates potential outcomes of ongoing discussions around export controls", a phrasing that writes export policy into the company's forward numbers as a known risk rather than a contingent one. The raised guidance is the defensible counter-reading: underlying demand for EUV and qualified DUV tools remains strong enough to absorb a seventeen-percentage-point shift in geographic mix, and ASML's near-monopoly position on EUV production is not materially changed by a China revenue reset. On that view the share-price reaction prices political risk rather than operational weakness.
ASML's historical R&D funding model cross-subsidised leading-edge EUV development through mature-node DUV shipments, a significant share of which went to Chinese chipmakers. A seventeen-percentage-point shift in one quarter is a structural step-change rather than a trajectory, and if the proposed US bill becomes law the cross-subsidy shrinks further. European semiconductor sovereignty at the leading edge rests on a firm whose R&D cash flow is being reshaped by export controls set in Washington, and the Commission has no comparable capital instrument to replace the lost Chinese revenue inside the European industrial base.
Brussels has stopped restating the end-of-decade target of twenty per cent global semiconductor market share since the Intel Magdeburg cancellation and the GlobalFoundries Crolles suspension, and Italy's €211m photonic chips state aid is closer to a pivot than a replacement. With ASML's Chinese revenue thinning and no European alternative supplier of EUV scanners, the leading-edge layer of European semiconductor capacity now depends on a single firm whose quarterly numbers are a readout of US trade policy as much as of its own order book.
