BE Semiconductor Industries N.V. Announces Temporary Disruption at Shah Alam, Malaysia

Production Facility. Q4-21 Order Update

Duiven, the Netherlands, December 20, 2021 - BE Semiconductor Industries N.V. (the "Company" or "Besi") (Euronext Amsterdam: BESI; OTC markets: BESIY, Nasdaq International Designation), a leading manufacturer of assembly equipment for the semiconductor industry, today announced that extended, record rainfall affecting its main production facility in Shah Alam, Malaysia caused flooding of the assembly floor for die attach systems. As a result, the final assembly of approximately 60 die attach systems with a value of approximately € 25 million was halted temporarily. All of such systems were scheduled for shipment in the fourth quarter of 2021. The rainfall stopped on Sunday, December 19 and permitted remediation work to commence immediately thereafter. All Besi APac employees are safe.

Besi believes that delays resulting from this weather event could cause its anticipated revenue for the fourth quarter of 2021 to decline by approximately 15-20% versus Q3-21 as compared to prior guidance of a decrease of 5-15%. The impact of the flooding will have minimal effect on Besi's planned ramping of hybrid bonding system production scheduled for the first half of 2022.

First estimates of one-time costs associated with materials and labor necessary to repair or reproduce any systems affected are in the range of € 4-6 million and will be taken as a charge to fourth quarter 2021 earnings. Estimated costs to repair the affected building and production related equipment are not expected to exceed € 2 million.

In addition, Besi also announced that its orders for the fourth quarter of 2021 will approximate € 180-€ 190 million versus the € 157.3 million recorded in the fourth quarter of 2020. Current order strength reflects favorable demand trends for its advanced packaging portfolio in its traditionally weakest quarter of the year.
