Shares of ASMPT (00522) plunged 5.04% in intraday trading, as investors reacted to the company's disappointing third-quarter results for 2025. The semiconductor equipment manufacturer reported a net loss of HK$268.6 million, a stark contrast to the profit recorded in the same period last year, despite showing growth in revenue and new orders.

The substantial loss was primarily attributed to HK$371 million in restructuring costs and inventory write-offs related to the voluntary liquidation of its subsidiary, Advanced Semiconductor Equipment (Shenzhen) Co., Ltd. (AEC). This one-time expense overshadowed the company's otherwise improving operational metrics, including a 9.5% year-over-year increase in revenue to HK$3.66 billion and a 14.2% rise in new orders to HK$3.621 billion.

Looking ahead, ASMPT provided an optimistic outlook for the fourth quarter, projecting revenue between US$470 million and US$530 million. This guidance represents a sequential growth of 6.8% at the midpoint and a 14.3% year-over-year increase. Analysts at Huatai Securities noted that while the one-time factory closure costs significantly impacted Q3 results, the upbeat Q4 revenue guidance and continued progress in advanced packaging products for 2026 remain positive factors for the company's long-term prospects.
