2026-08-04 — China lithography roadmap review; DUV pace confirmed, EUV prototype still chipless

• A same-day roadmap review confirms China’s domestic tool-maker Shanghai Aishengna is on pace for roughly 5 immersion DUV machines a year, and notes China’s separate Shenzhen-based EUV prototype effort has produced no usable chips yet.

2026-08-02 — CXMT’s LPDDR6 push shows a DUV performance ceiling (unverified)

• TechTimes reports CXMT nearing LPDDR6 memory production but flags a 12.8 Gbps vs. 14.4 Gbps performance gap attributed to China’s DUV-only (no EUV) manufacturing ceiling — thin: article body was blocked (403), headline only. ⟨crawl 2026-08-04⟩

2026-07-30 — Domestic 7nm scanner forecast lands much later than the breaking story implied

• An AI Futures Project forecast (June 2026) puts a commercially viable Chinese domestic 7nm immersion scanner between 2032 and 2038 (median 2035) — far beyond the “delivered this year” framing of the 2026-07-28 breaking story below.

2026-07-29 — The reverse-engineering ceiling, explained

• A full-text policy piece (War on the Rocks) lays out why China’s EUV reverse-engineering push can’t just leapfrog ASML: ASML’s EUV machines have 100,000+ components (700,000 at subsystem level) from ~5,000 suppliers, cost ~$180M (standard) to ~$380M (High-NA), and depend on tacit, path-dependent systems-integration knowledge that component-level reverse engineering (reported use of former ASML engineers, per a Dec-2025 report) doesn’t capture — plus supply-chain chokepoints entirely outside China’s reach: Japanese photoresist makers JSR/TOK/Shin-Etsu, Tokyo Electron’s near-monopoly on EUV photoresist coaters/developers, Hoya/AGC on mask blanks, KLA on metrology, and Lasertec’s near-monopoly on actinic mask inspection. ASML also runs ~10,000 field-support engineers who need close to a year of training each — a services moat on top of the hardware one. ⟨crawl 2026-08-04⟩

2026-07-28 — Shanghai Aishengna named as China’s first domestic immersion-DUV maker

• Shanghai Aishengna Electronic Technology Group (state-owned, founded 2023, 7B yuan/$1B registered capital, absorbing engineering teams from Huawei-affiliated startup Yuliangsheng and state scanner maker SMEE) is confirmed as the maker behind China’s first domestically-produced immersion DUV lithography tools — ~5 units targeted for 2026, ~20 for 2027, with first deliveries to SMIC, Hua Hong, and CXMT this year for production-line validation (SMIC reportedly testing a unit since 2025-09). The tool prints 28nm-class features in a single exposure (7nm-class only via multi-patterning) — consistently described as “a generation behind” ASML, which still holds an estimated ~98.7% of the global immersion-lithography market. This is the same story this repo’s china-duv-lithography thread already tracks; the identity and detail here are fresher.

2026-06-24 — Dutch government still irritated over MATCH Act’s reach

• Dutch government reported “irritated” by new US ASML restriction plans, continuing pushback that began with April’s royal visit to Washington below. (NL Times) ⟨crawl 2026-08-04⟩

2026-06-19/21 — ASML denies an EUV tool ever reached China

• ASML publicly denied allegations behind the Lutnick inquiry (below): the company states none of its 314 operational EUV machines worldwide (plus 26 decommissioned) are located in China, calling the allegations “false and reputation-damaging.” A confirmed violation would breach the multilateral Wassenaar Arrangement. No source found confirms a resolution either way as of this crawl (2026-08-04) — the matter appears to remain open. (TechTimes, Asia Times) ⟨crawl 2026-08-04⟩

2026-07-15 — Q2 2026 earnings: guidance raised again, and Intel ships the first High-NA logic chips

• ASML’s Q2 2026 results: €9.3B net sales, €2.9B net income (31.3% margin), 54.0% gross margin, €7.59 EPS, 86 new + 5 used systems sold, system mix Logic 51%/Memory 49%, free cash flow €1.3B. Full-year 2026 guidance raised to €43-45B net sales, 54-56% gross margin (up from April’s €36-40B/51-53%); Q3 2026 guided €11.0-12.0B revenue, 55-57% gross margin. Quarterly net-bookings disclosure appears to have quietly stopped — H1 order intake was only characterized as “very strong.” 2027 EUV order coverage called “close to being fully covered,” with a planned 30% capacity increase for both low-NA EUV and DUV immersion systems. (ASML press release / GlobeNewswire) ⟨crawl 2026-08-04⟩
• Same day: Intel Foundry became the first company anywhere to ship high-volume commercial logic made with ASML’s High-NA EUV tool — select layers of Intel 18A-node Core Ultra Series 3 (“Panther Lake”) chips, with yields on those “dual-qualified” layers already matching the established (lower-NA) platform. This is a production-readiness milestone on select layers, not a full-chip High-NA process yet. (ASML press release, corroborated by SiliconANGLE/Tom’s Hardware/ TechTimes) ⟨crawl 2026-08-04⟩
• CFO Roger Dassen, same call: “We still look at China as approximately 20% of our total net sales, so that percentage hasn’t changed” — attributed to domestic-led logic-chip demand moving in sync with global demand. This sits against a reported H1 2026 actual of 16% (down from 19% in Q1, 36% in Q4 2025) — the two figures aren’t reconciled by any source found; both are carried rather than picked.

2026-04-15 — Q1 2026: guidance set with export-control risk already priced in

• CEO Christophe Fouquet, Q1 2026 results: full-year guidance set at €36-40B net sales, 51-53% gross margin, with Fouquet stating directly that “the bandwidth in our 2026 guidance accommodates potential outcomes of ongoing discussions around export controls” — guidance was built with the fight below already in mind.

2026-04-02/08 — The MATCH Act: a real legislative vehicle targeting DUV, not just EUV

• The MATCH Act (Multilateral Alignment of Technology Controls on Hardware Act) was introduced in both chambers — House sponsor Rep. Michael Baumgartner; Senate companion S. 4281 (Sens. Pete Ricketts, Andy Kim, co-sponsored by Senate Democratic Leader Chuck Schumer). It would classify all DUV immersion lithography tools (not just EUV) as “covered semiconductor manufacturing equipment,” give Commerce 150 days to certify the Netherlands and Japan have matched US-style country-wide controls, or else unilaterally extend US jurisdiction via the Foreign Direct Product Rule. It later passed the House Foreign Affairs Committee (a countrywide cryogenic-etch ban was stripped first; DUV restrictions survived), reported as the “largest export control markup in the history of Congress.” One analysis judges it will pass the House this year but not become law in the 119th Congress, with the Senate side possibly folded into the NDAA instead. ASML shares reportedly fell ~3.44% on the initial news. (Yahoo Finance, TechWireAsia, NBC News, ChinaTalk, Manufacturing Dive) ⟨crawl 2026-08-04⟩
• Dutch PM Rob Jetten named ASML export controls as a primary reason for King Willem-Alexander and Queen Máxima’s April 2026 state visit to Washington, including a White House dinner with President Trump — talks described as “constructive but without consensus.” (NL Times, MarketScreener, MLQ News) ⟨crawl 2026-08-04⟩
• Around the same period, Commerce Secretary Howard Lutnick began privately questioning senior ASML executives over a concern that an EUV lithography system may have reached China in violation of export controls — see ASML’s denial above (2026-06-19/21).

2025-09-09 — ASML leads Mistral AI’s Series C, becomes its largest shareholder

• ASML invested €1.3B (~$1.5B) as lead investor in Mistral AI’s Series C, taking an ~11% fully-diluted stake and valuing Mistral at ~$13.8-14B — ASML’s largest single shareholder. ASML CFO Roger Dassen holds the company’s seat on Mistral’s Strategic Committee, confirmed still active into 2026. As of this crawl (2026-08-04): Mistral is reportedly “in talks” for a new round at $23B valuation ($3.5B raise), but no source confirms whether ASML is participating — status unresolved.

2024-12-05 — The standing US legal mechanism (background)

• BIS’s Foreign-Produced Direct Product Rule update set a 0% de-minimis threshold for certain lithography equipment, giving the US jurisdiction leverage over ASML indirectly via Cymer, its San Diego-based excimer-laser subsidiary — the active legal mechanism underneath the 2026 fight above, unchanged this crawl window.
