Q4 2026	Mass production of HBM4	Supply to NVIDIA and Google	Compete for AI memory market
2028	Full operation of P5	Invest hundreds of billions to trillions of KRW	Double production capacity

• Equivalent to the total capacity of P3 and P4 (“three-story factory” design)
• Expected to be put into production in 2028, but may be further advanced
• Adopt simultaneous construction mode to shorten construction period[4][5]

Samsung has used counter-cyclical capacity expansion strategies to attack competitors multiple times in history[6][7]:

• Expanded capacity against the trend during the 2008 financial crisis, and market share exceeded 40% in 2010
• Continued investment during the industry trough in 2015-2016, laying the foundation for the subsequent AI demand surge
• Obtained excess profits during the industry recovery period through scale advantages

1. AI Demand Surge:
   DRAM demand is expected to grow 26% year-on-year in 2026, while supply will only grow 20%
2. High Prices:
   The price of 32GB DDR5 modules rose from $150 in September to $239 in November (a 60% increase)
3. Competitive Pressure:
   Respond to SK Hynix’s strong challenge in the HBM market (55% vs 30% market share)
4. Strategic Positioning:
   Lock in market share in the AI boom period of 2026-2028 in advance

Risk Type	Trigger Condition	Expected Impact	Probability
Price Downside Risk	Samsung’s capacity release + industry cycle reversal	DDR5 prices drop by 30-40%, gross profit margin comes under pressure	35%
Price War Risk	Samsung regards CXMT as a major threat	The overall profitability of the industry drops by 20-30%	25%
Overcapacity Risk	Early release of P4/P5 + HBM demand falls short of expectations	General DRAM prices come under pressure	40%

Despite facing pressure from Samsung’s capacity expansion, CXMT still has important structural opportunities[1][2][6][7]:

1. HBM Capacity Crowding Effect:
   • The three major manufacturers have shifted about 50% of their capacity to HBM and high-end products
   • Supply of general DRAM (such as DDR4, DDR5) remains tight
   • Creates a market entry window for CXMT

2. Domestic Substitution Demand:
   • Supply chain security has become a core concern of domestic terminal manufacturers
   • Enterprises such as GigaDevice have strengthened cooperation with CXMT (expected transaction volume of $161 million in 2025)
   • Domestic server manufacturers have a strong willingness to diversify supplier risks

3. Super Cycle Dividends:
   • The “super cycle” of the memory industry is expected to last until the end of 2027
   • The overall DRAM price is expected to rise 58% year-on-year in 2026
   • The industry’s return on capital expenditure is at a historical high

---

• Accelerate yield improvement of DDR5 products (target: increase from 70% to 85%)
• Complete the verification process of mainstream server manufacturers
• Establish large-scale mass production capacity for LPDDR5X products

• Develop next-generation 1b nm process technology
• Layout HBM product R&D (maintain technical reserves even if mass production is not possible)
• Promote high-end product lines such as MRDIMM

• Achieve technological synchronization with Samsung and SK Hynix (1c nm process)
• Develop differentiated technologies (such as Processing-in-Memory (PIM))
• Establish a complete IP protection system

Priority	Customer Type	Strategy Focus	Cooperation Depth
Tier 1	Domestic server manufacturers (Inspur, Huawei, ZTE)	Exclusive supply agreements, customized product development	Joint R&D, capacity guarantee
Tier 2	Domestic AI chip manufacturers (Cambricon, Hygon, etc.)	Technological collaboration, solution integration	Early product introduction, reference design
Tier 3	Consumer electronics brands (Xiaomi, OPPO, vivo)	Cost-performance advantage, rapid response	Diversified product portfolio, localized services
Tier 4	Overseas second-tier manufacturers	Differentiated positioning, flexible pricing	Agent channel construction, technical support

• 2026 target: 400,000 wafers per month (33% increase from 2025)
• 2027 target: 500,000 wafers per month
• 2028 target: 600,000 wafers per month (reaching SK Hynix’s current scale)

1. Scale Effect:
   For every doubling of capacity, unit cost decreases by 15-20%
2. Yield Improvement:
   Increasing from 70% to 85% brings about 10% cost improvement
3. Equipment Localization:
   Domestic substitution of key equipment can reduce equipment costs by 20-30%
4. Material Optimization:
   Cooperate with domestic material suppliers to reduce raw material costs by 15%

Product Field	Competition Intensity	CXMT’s Strategy
HBM Market	Extremely High (led by SK Hynix)	Wait-and-see + technical reserves, no mass production for now
General DDR5	High (Samsung, Micron)	Focus on niche markets (domestic substitution for servers)
LPDDR5X	Medium (led by Apple, Samsung)	Focus on the mid-to-low-end market of the Android camp
Niche DRAM	Low (led by Taiwanese manufacturers)	Seize market share and build brand awareness
Emerging Applications	Low (automotive, IoT, AI edge computing)	Layout in advance

• Supply chain security has become a core concern of domestic terminal manufacturers
• CXMT is the only domestic enterprise with advanced DRAM mass production capacity
• Policy support continues to increase (tax incentives, R&D subsidies, government procurement)

1. Establish a strategic customer reserve pool (lock in the top 20 domestic server and PC manufacturers)
2. Build an ecological alliance (cooperate with domestic CPU/GPU, module manufacturers, and system integrators)
3. Seek policy support (be included in national major projects, priority in government procurement)

• Maintain operating capital reserves of more than 12 months
• Establish a special equipment renewal fund (to cope with technological iteration)
• Optimize capital structure and reduce financial leverage

• Promote the IPO process (current valuation is approximately RMB 140 billion)
• Introduce strategic investors (industrial capital, state-owned capital)
• Seek support from policy bank loans

---

AI demand falls short of expectations, terminal consumption remains weak, and the three major manufacturers release capacity too quickly

• Accelerate collection of customer advance payments to lock in orders
• Moderately reduce capacity utilization and control inventory
• Increase R&D investment to prepare for the next upward cycle
• Seek financial support from the government and strategic investors

Samsung judges that CXMT’s threat has risen significantly, needs to maintain market share, and has serious inventory backlog

• Do not participate in price wars and stick to the bottom line of gross profit margin
• Focus on differentiated products and specific niche markets
• Accelerate technological iteration to narrow the generational gap with Samsung
• Maintain orders through domestic substitution demand

Early release of P4/P5 capacity, HBM demand falls short of expectations, global economic recession

• Adjust the pace of capacity expansion to avoid overcapacity
• Increase the proportion of niche products to improve anti-cycle capabilities
• Accelerate layout in high-end fields such as HBM
• Seek differentiated competitive positioning with Samsung

---

CXMT should adopt the overall strategy of

:

• Short-Term:
  Focus on the domestic substitution market and establish a stable customer base
• Medium-Term:
  Gradually increase market share through technological iteration and capacity expansion
• Long-Term:
  Become the world’s fourth-largest DRAM manufacturer, forming a “four-strong pattern” with Samsung, SK Hynix, and Micron

1. Technological Breakthrough:
   Achieve mass production of 1b nm process as soon as possible to shorten the technological gap with Samsung
2. Customer Binding:
   Establish 3-5 strategic customers for deep-bound long-term cooperation
3. Capacity Expansion:
   Maintain an annual capacity growth rate of more than 30% and use scale effects to reduce costs
4. Financial Soundness:
   Maintain sufficient cash reserves and financing capabilities to enhance anti-cycle capabilities
5. Ecosystem Construction:
   Establish a complete industrial ecosystem to form synergistic effects

Phase	Time Point	Core Goal
Short-Term	2026	Increase DRAM market share to 12%, DDR5 share to 15%
Medium-Term	2027	Achieve break-even and establish complete HBM technical capabilities
Long-Term	2028	Become the world’s fourth-largest DRAM manufacturer with a market share of over 15%

1. If Samsung accelerates capacity expansion, DRAM prices may enter a downward cycle in advance
2. Failure to meet expectations in technology and yield improvement may affect profitability
3. Geopolitical factors may affect equipment procurement and overseas market expansion
4. Funding pressure may restrict expansion speed and R&D investment
