ASMPT (SEHK:522) Stock Sinks Despite AI Packaging Margin Surge

ASMPT heads into this earnings season with the stock under pressure, down about 19% over the past week and more than 40% over the past month, yet the latest quarter reads very differently from that price action. Q2 2026 revenue reached HK$4,935.8m and basic earnings per share came in at HK$1.00, helped by strong bookings and a group net margin of 9.6% over the trailing twelve months. For a company long treated as a cyclical packaging supplier, this set of numbers puts the focus firmly on profitability quality and where the valuation now sits after the selloff.

Impressed by ASMPT’s profitability but uneasy about the sharp share price drop and what it might signal for risk? Take a look at our screener of 304 resilient stocks with low risk scores to compare ASMPT with companies that have steadier risk profiles.

Bull Case Stress Test for ASMPT’s AI Packaging Story

Bulls argue that ASMPT’s leadership in advanced packaging for AI and HBM gives it durable growth and stronger margins. Q2 and H1 results go some way to backing that up. Advanced packaging revenue grew 17% year on year and now contributes about 30% of group revenue. Semi solutions, which include TCB and photonics, delivered a Q2 adjusted margin of about 46.5%, well above group levels, while group adjusted gross margin reached 42.5% in Q2. Bookings of US$1.63b for H1 with a book to bill of 1.43 point to healthy demand, helped by repeat Firebird TCB tool orders and strong photonics revenue of about US$75m. The interim dividend of HK$0.97 per share and roughly 50% payout policy indicate that this margin profile is already translating into cash returns rather than remaining only a narrative in presentations.

Bear Case Stress Test on Cyclicality and Competition

Bears worry that ASMPT’s earnings are highly cyclical, overexposed to China and vulnerable to tougher competition as AI packaging matures. The share price has fallen about 19% over 7 days and about 43% over 30 days, which suggests rising concern despite strong Q2 numbers. Revenue from China is 42% of the total, so any policy shifts or local competitor gains would have an impact. Management also highlights risks around HBM4 and HBM5 timing and the need for sustained heavy R&D and capex. A book to bill of 1.43 and lengthening conversion times of 6 to 9 months mean strong H1 bookings could reverse quickly if customers change rollout plans. The announced CEO transition in August 2026 adds another execution risk factor for a business that still depends on semiconductor capex swings.
