JCET Technology's 2025 results beat expectations; UBS maintains Buy

Overview

This report is UBS's earnings review on JCET Group (600584.SS). The report argues that the company's 2025 attributable net profit declined YoY but still beat expectations, mainly supported by Q425 gross margin improvement, optimized product mix, and high utilization at domestic plants. UBS remains constructive on the company's investment and growth potential in advanced packaging, AI-related applications, and 2.5D OSAT.

Core views

Key views include: first, 2025 results beat expectations, with Q425 gross margin reaching 15.3%, the highest since Q422; second, downstream application mix improved, as consumer electronics, computing, automotive, and industrial & medical all grew YoY in H225, while communications-related applications declined; third, the advanced packaging subsidiary JCAP delivered 20% revenue growth and 48% profit growth, outperforming the group overall; fourth, the company plans 2026 capex of close to Rmb10bn, signaling a positive outlook for new business lines and advanced packaging; fifth, UBS maintains a Buy rating, but lowers the target price slightly to Rmb56.70 due to a lower 2026E BVPS.

Analysis framework

The report uses earnings decomposition, downstream application revenue-mix analysis, subsidiary operating-performance analysis, capex plan assessment, and a P/BV valuation framework. Based on 2025 annual results, UBS cut 2026-27E earnings estimates, mainly because expense assumptions were raised, including higher R&D spending, while essentially maintaining its 2028E earnings forecast.

Methodology notes

• Valuation methodsP/BV

  Price-to-book valuation

  UBS's target price is based on P/BV valuation, with the target P/BV maintained at 3.3x; the target price cut mainly reflects a lower 2026E BVPS driven by downward earnings revisions.

• earnings_reviewprofit_forecast_revision

  Earnings forecast revision

  Based on 2025 results, UBS cut 2026-27E earnings by 9.6% and 4.7%, respectively, mainly due to higher expense and R&D assumptions, while essentially keeping the 2028E earnings forecast unchanged.

  Core coverage name

  Strengths

  2025 results beat expectations, with clear progress in advanced packaging and AI-related products, and higher 2026 capex supporting new business lines.

  Weaknesses

  2025 attributable net profit still declined YoY, 2026-27E earnings were cut, and pressure from expenses and R&D spending increased.

  Comparison

  JCAP outperformed the group overall; the company is a major player in the global OSAT market and was the world's third-largest OSAT company by revenue in 2022.

  Risks

  Semiconductor cycle weakness, margin pressure from intensifying competition, and loss of overseas customer share due to geopolitics.

Impact & implications

The report implies that JCET Technology's investment thesis is gradually shifting from traditional communications and smartphone-related businesses toward computing, automotive, industrial & medical, AI-related applications, and advanced packaging. Higher capex may add near-term cost pressure, but it also strengthens the long-term growth path. If the share of high-growth applications continues to rise, the revenue mix from computing applications may increase further and support the company's valuation.

Risks

• The global semiconductor industry is highly cyclical, and a broad slowdown in demand could weigh on the company's earnings.
• More new entrants in China's OSAT industry could intensify competition and compress gross margins.
• Geopolitical factors may reduce the company's share among overseas customers.
• Higher capex, R&D, and expense investment may pressure near-term profitability.

What to watch

• The rollout pace and allocation of the nearly Rmb10bn 2026 capex.
• Mass-production and customer qualification progress for advanced packaging, 2.5D OSAT, XDFOI chiplet, and SiPh optical engine products.
• Whether the revenue share of high-growth applications such as computing, automotive, and industrial & medical continues to rise.
• Whether the decline in communications-related application revenue stabilizes.
• Whether gross margin can sustain the Q425 improvement trend.
