On Tuesday, ASM International NV (AS:ASMI) shares climbed after the Dutch chipmaker raised its Q4 sales guidance, probably due to a reduction in the expected impact of US export restrictions on revenue from China.

The company now anticipated that the regulations would negatively impact 15% – 25% of sales to China, down from its initial projection of 40% or more, following extensive clarifications and internal reviews.

Reportedly, the new turnover projection in China, along with a little higher conversion of backlog into shipments in other regions, led ASMI to upgrade its current quarter sales outlook to €630 million – €660M, up from its prior estimate of €600M – €630M (€1 = $1.038). ASMI will report its results for February’s final three-month period of its 2022 fiscal year.

Washington’s export restrictions prohibit American companies from shipping parts needed for semiconductor manufacturing in China. US citizens and companies are also barred from giving their support directly or indirectly to Chinese businesses that operate in advanced chip-making.

Notably, equipment sales to China are vital for ASMI. It accounts for more than a sixth of its total revenue in the year’s first nine months.
