ASML just gave us a first glimpse into how U.S. chip export curbs will dent its China sales

ASML finally offered a first glimpse into how U.S. restrictions on exports of its advanced chip manufacturing tools to China will impact its sales in the Asian country.

The Netherlands-based chip equipment maker said in its earnings report Tuesday, which was released a day early due to a "technical error," that it expects net sales for 2025 to come in between 30 billion euros and 35 billion euros ($32.7 billion and $38.1 billion). This is at the lower half of the range ASML had guided previously.

ASML is a critical part of the global chip supply chain. The firm's extreme ultraviolet lithography machines are used by many of the world's largest chipmakers — from Nvidia to Taiwan Semiconductor Manufacturing — to produce advanced chips.

While third-quarter net sales at the firm reached 7.5 billion euros — beating expectations — net bookings came in at 2.6 billion euros ($2.83 billion), the company said. That was well below a 5.6 billion euro consensus estimate from LSEG.

ASML shares plunged as much as 16% on Tuesday in response, causing the firm to shed over $50 billion in market capitalization in a single day, according to CNBC calculations using LSEG data.

Beyond the disappointment on bookings — which analysts said was due to weakness in a select number of customers, including Intel and Samsung — AMSL also gave an indication of how geopolitical tensions are putting pressure on its 2025 outlook.

Roger Dassen, ASML's chief financial officer, said on a call with analysts Wednesday that the company expects China sales to drop next year, citing U.S. export restrictions as one of the reasons.

"We all read newspapers, right? We all see that there is speculation around around export control," Dassen said in response to an analyst
