QUESTION MARKS - MEMORY AND STORAGE PACKAGING INTEGRATION

Following the strategic acquisition of a majority stake in SanDisk Semiconductor Shanghai, the memory packaging segment represents a significant question mark with high growth potential. The global memory packaging market is rebounding with an estimated 15% growth rate in 2025 driven by surging NAND and DRAM demand for AI workloads. JCET currently holds approximately a 6% global market share in independent memory OSAT services and targets expansion to ~12% through integration of Western Digital-related assets and cross-selling to existing customers.

Key financial and operational parameters for the memory packaging integration are summarized below:

Primary risks include high upfront capital intensity, integration execution risk, customer retention during transition, and short-term margin dilution. Critical success factors are manufacturing yield improvements, qualification cycles with hyperscalers, and price leverage through higher volume.

• Required investments: 2.0 billion RMB in 2025 for advanced packaging lines and automation.
• Breakeven horizon: projected 24-36 months post-majority integration assuming 10-15% CAGR of secured memory demand from existing customers.
• Synergy drivers: cost rationalization, shared R&D, and supply-chain optimization expected to lift margins to industry peer levels.

QUESTION MARKS - ARTIFICIAL INTELLIGENCE EDGE COMPUTING MODULES

The emerging market for AI edge computing packaging is expanding rapidly at an estimated 40% annual growth rate. JCET's current share in this fragmented niche is below 4%, making it a high-risk, high-reward question mark. The segment requires intensive R&D and specialized packaging techniques to meet latency, power, and thermal constraints for edge AI devices.

Strategic actions required:

• Accelerate R&D funding to sustain 12% of segment sales until product-market fit.
• Form design partnerships with global chipset designers to qualify proprietary interconnects.
• Invest in modular manufacturing cells to enable rapid capacity ramp and protect margins.
• Evaluate targeted M&A of boutique OSATs to acquire IP and customer relationships.

QUESTION MARKS - PHOTOVOLTAIC AND GREEN ENERGY PACKAGING SOLUTIONS

JCET is exploring specialized packaging for renewable energy semiconductors where semiconductor content is increasing ~25% annually. The company's current share in this vertical is estimated at ~2%, competing against established industrial specialists. Significant CAPEX and qualification cycles are required to develop high-reliability packaging that endures outdoor environments for 20+ years.

Key considerations and tactical levers:

• Leverage automotive-grade reliability platforms to shorten qualification time for outdoor-rated packages.
• Allocate targeted CAPEX for environmental stress screening, extended life-cycle testing, and IEC/UL certifications.
• Prioritize partnerships with inverter and solar module OEMs to secure design wins and volume commitments.
• Monitor unit economics closely: current low revenue contribution (<2%) necessitates staged investment tied to secured customer contracts.

JCET Group Co., Ltd. (600584.SS) - BCG Matrix Analysis: Dogs

Dogs - legacy and low-growth legacy businesses pose ongoing threats to JCET's portfolio and capital allocation. The following section details three specific Dog-category activities: legacy leadframe packaging for low-end consumer, traditional wire bonding for mature sensors, and basic discrete semiconductor testing services, with quantitative metrics, strategic responses, and near-term financial impacts.

LEGACY LEADFRAME PACKAGING FOR LOW-END CONSUMER: The market is contracting at an annualized rate of -6% as OEMs migrate to advanced substrates (FC, WLP, SiP). This segment currently contributes 4% to JCET's consolidated revenue (2025E), equating to ~RMB 1.2 billion based on group revenue guidance of RMB 30 billion. Market share erosion continues toward lower-cost Southeast Asian competitors; JCET's share in this niche is estimated at 12% versus 22% three years prior.

Key operational and financial implications for legacy leadframe packaging include:

• Compressed EBITDA contribution: segment EBITDA margin ~1.5%-2.5% (2025 estimate).
• Negative return on incremental maintenance CAPEX given low utilization and price pressure.
• Strategic redeployment: CAPEX and R&D prioritized to HPC and automotive packaging where target ROIC >12%.

TRADITIONAL WIRE BONDING FOR MATURE SENSORS: Wire bonding for basic sensors is being cannibalized by integrated MEMS and SiP solutions. The business experienced an 8% YoY revenue decline in 2025. JCET's share in this legacy niche has slipped below 5% as corporate focus shifts to flip-chip and wafer-level packaging. When accounting for rising specialized labor and raw material input costs, the ROI of continuing these legacy lines is negative.

Management actions and risk factors for wire bonding legacy lines:

• Evaluation of module closures to reduce fixed-cost drag; potential one-time impairment of RMB 60-90M.
• Reassignment of technical staff to advanced assembly lines where feasible; severance and retraining costs estimated RMB 10-20M.
• Counterparty risk: loss of OEM contracts as clients redesign to SiP/MEMS.

BASIC DISCRETE SEMICONDUCTOR TESTING SERVICES: Standalone testing for basic discrete devices is a low-growth commodity business, growing ~1% annually. JCET's revenue from this activity has plateaued at

Operational levers applied to this testing segment:

• Selective contract non-renewals to eliminate sub-1% margin accounts.
• Consolidation of test assets into multi-product lines to lift utilization toward corporate target (aim: raise from current ~58% to 80% where possible).
• Redirected capex and engineering resources toward automated, high-value test solutions supporting automotive and HPC customers.
