ASML's China Exposure Hinges on MATCH Act Loopholes as Buyback Programme Rolls On

ASML investors are juggling two very different storylines this week: a US legislative fight that will determine how much of its China business survives, and a steady drumbeat of share repurchases that puts real cash behind the company's own confidence.

A Bill With a Carve-Out

The MATCH Act, introduced in April, has been folded into the US defence budget for fiscal year 2027, according to a Korea Times report. The draft now awaits full Senate deliberation and reconciliation between the House and the Senate. If the Netherlands and Japan align their export controls with Washington's, equipment from ASML and Tokyo Electron could fall within its scope.

One provision would exempt shipments to existing, foreign-operated plants in China — potentially covering Samsung's NAND fab in Xi'an and SK hynix's DRAM and NAND sites in Wuxi and Dalian. Whether servicing work would also be captured remains unresolved. Such carve-outs could shield ASML's business with those facilities, provided they survive into the final statute and the export rules that follow. For shareholders, both the political deal and the precise reach of the rules matter.

The pressure from Washington may stretch further than the bill itself. Media reports suggest the US could push the Netherlands to halt nearly all ASML shipments of chipmaking equipment to China. The MATCH Act would also prod allies toward restricting older DUV tools.

Should investors sell immediately? Or is it worth buying ASML Holding?

China Still Looms Large

China accounted for 23% of ASML's system sales in the third quarter of 2026, up from 14% in the prior quarter — a reminder of how much is at stake. That regional split covers system sales only, not group revenue.

ASML has never shipped an EUV scanner to China; Dutch authorities blocked those exports in 2019. Older DUV scanners already require a national export licence, so any tightening would hit a segment where deliveries are still possible on approval. Chinese memory makers CXMT and YMTC have reportedly stockpiled enough ASML DUV equipment to cover their expansion plans for the next three years, a hedge against further restrictions.

Buyback Adds a Tangible Thread

Alongside the policy noise, ASML disclosed on Monday the repurchase of 422,800 shares for a total of EUR 562,800,515. The transactions, executed last week, fall under the company's 2026–2028 buyback programme.

The stock gained 2.3% yesterday, carried by a broader rally in chip equipment makers and a recovery in semiconductor and AI shares. That move has put the durability of the investment case under the microscope: further gains look plausible only if announced fab projects move from intention to firm commitment. Samsung Electronics and SK hynix have both unveiled plans, and the market is watching for them to harden.

What Could Break the Narrative

The chief risk sits in how early those fab plans are. Delays in fleshing them out or getting them built would sap the investment thesis, leaving a rally built on expectations more exposed to a rethink. A fading recovery across the wider AI and semiconductor complex would cost ASML part of its tailwind — especially painful if progress on the announced plants stalls at the same time. In that scenario, the buybacks would stand as a company-level positive while the investment outlook weakened.

For now, the combination of concrete corporate action and a friendlier industry backdrop supports the recovery, so long as both keep pointing the same way. The next real catalysts are further details on the Samsung and SK hynix projects and fresh buyback disclosures showing how the programme is being executed. On the policy side, the question is which tools, customers and services the final rules capture — a broad ban would hurt ASML far more than a framework that preserves exemptions for foreign-operated fabs.
