Strategic Analysis of Micron Technology's Acquisition of Powerchip Semiconductor Manufacturing Corporation (PSMC)'s Tongluo Fab

Based on the latest market data and transaction information, I will conduct a systematic and comprehensive analysis of Micron Technology’s strategic layout for acquiring Powerchip Semiconductor Manufacturing Corporation (PSMC)'s fab.

---

• Acquisition Price:
  $1.8 billion (approx. NT$56.9 billion)
• Target Assets:
  PSMC’s Miaoli Tongluo P5 wafer fab, including approximately 300,000 square feet of clean room space
• Transaction Timeline:
  Completion expected in Q2 2026, with phased transfer within 18 months after the formal contract is signed
• Supporting Agreement:
  The two parties will establish a long-term DRAM advanced packaging wafer foundry partnership

Manish Bhatia, Executive Vice President of Global Operations at Micron, stated that this acquisition can complement Micron’s existing layout in Taiwan. The Tongluo fab is geographically close to the Taichung plant, which helps enhance overall operational synergies [1][2]. This marks Micron’s latest major layout amid the AI memory capacity expansion wave, and is also a key step in PSMC’s promotion of its fourth transformation.

According to the latest data from Omdia, the total wafer output of the world’s three major DRAM original manufacturers is expected to reach 18 million wafers in 2026, a year-on-year increase of approximately 5%. However, this capacity expansion rate is still insufficient to meet market demand [3][4].

Manufacturer	2025 Capacity (10,000 wafers)	2026 Capacity (10,000 wafers)	YoY Growth	Main Capacity Source
Samsung Electronics	759	793	+5%	Pyeongtaek Plant
SK Hynix	597	648	+8%	Cheongju M15X Plant
Micron Technology	360	360	~0%	Existing Facilities

1. Priority Allocation of HBM Resources:
   Suppliers allocate approximately 60% of advanced process capacity to HBM and server DRAM, leading to tight supply of DRAM for PCs and mobile devices
2. New Process Conversion Losses:
   Samsung is facing temporary capacity losses during the transition to the 10nm 6th generation (1c) process
3. Long New Plant Cycle:
   Samsung’s Pyeongtaek P4 plant is not expected to start production until after 2027, and SK Hynix’s Yongin Cluster will not be put into operation until after 2027 at the earliest

• Record Low Demand Satisfaction Rate:
  Currently, DRAM suppliers’ demand satisfaction rate for customers is only around 60%, and that for server-specific DRAM is even below 50%, indicating a 40-50% supply gap in the market [3][4]
• Continuous Price Surge:
  TrendForce predicts that DRAM contract prices in Q1 2026 will rise by 55-60% quarter-on-quarter, and the growth rate for server-specific DRAM will exceed 60%
• AI Demand Dominates Growth:
  The demand for high-performance DRAM in AI servers is experiencing explosive growth, and the HBM market size is expected to grow from $2.9 billion in 2024 to $15.7 billion in 2032

The global DRAM market will remain in short supply in 2026, and this supply-demand imbalance is expected to persist throughout the year. The gap is not expected to be substantially alleviated until Samsung’s Pyeongtaek P4 plant and SK Hynix’s Yongin Cluster are put into operation in 2027-2028. Until then, suppliers will maintain strong pricing power and substantial profits.

As the world’s third-largest DRAM manufacturer, Micron’s capacity plan for 2026 is relatively conservative, with annual output expected to remain at 3.6 million wafers, similar to 2025. Its main new capacity will be released in 2027-2028. However, Micron is making up for the lag in capacity expansion through a diversified strategy:

1. Technology Innovation-Driven:
   Micron has sold out all its 2025 HBM capacity and signed most of its 2026 supply agreements
2. U.S. Local Capacity Expansion:
   Investing $10 billion to build an advanced wafer fab in New York State
3. Strategic Acquisition to Strengthen Capabilities:
   Quickly acquire mature production capacity in Taiwan by acquiring PSMC’s Tongluo fab

• Leading HBM3E Technology:
  Micron has obtained certification from AI chip manufacturers such as NVIDIA, accelerating its catch-up with SK Hynix and Samsung in the HBM field
• Supported by High Profit Margins:
  Benefiting from the high ASP (Average Selling Price) of HBM and AI memory, Micron’s gross profit margin has improved significantly, reaching 56% in Q1 FY26, and is expected to jump to 68% in Q2
• High Order Visibility:
  Micron CEO Sanjay Mehrotra clearly stated that the tight memory market will continue beyond 2026, and the company has raised its 2026 capital expenditure to $20 billion

• Samsung’s Pyeongtaek P4 Plant
  will significantly expand capacity after 2027
• SK Hynix’s Yongin Cluster
  will be put into operation after 2027, and plans to invest $13 billion to build an advanced AI chip packaging and testing plant
• The Two Korean Giants
  have deep technical accumulation in the HBM field and lead in market share

Value Dimension	Analysis
Rapid Capacity Acquisition	Directly acquire an existing clean room, avoiding the 18-24 month construction cycle of building a new plant and reducing execution risks
Geographic Synergy	The Tongluo fab is adjacent to the Taichung site, forming a regional manufacturing cluster to improve supply chain efficiency
Advanced Packaging Cooperation	Establish a long-term DRAM advanced packaging foundry partnership with PSMC to improve the layout of post-process HBM manufacturing
Technology Transfer	Micron will authorize PSMC with 1Ynm and 1Znm DRAM process technologies to deepen cooperation

Institutional estimates show that the first phase of Micron’s Tongluo project will contribute capacity equivalent to more than 10% of Micron’s global capacity in Q4 2026 by the second half of 2027 [1]. This means Micron’s effective capacity in 2027 will be significantly increased.

PSMC has achieved its fourth strategic transformation through this transaction:

1. Financial Optimization:
   Obtain $1.8 billion in cash, improve capital structure, and reduce the capital-intensive pressure of a single fab
2. Technology Upgrade:
   Obtain authorization for Micron’s advanced DRAM process technologies to enter next-generation product lines
3. Supply Chain Integration:
   Integrate into Micron’s post-process HBM manufacturing supply chain, and reserve HBM PWF capacity through advance payment
4. Business Focus:
   Focus on high-value-added products (3D AI DRAM, WoW, silicon interposers, silicon capacitors, etc.), and gradually reduce non-AI related businesses

• The impact of Micron’s acquisition of PSMC’s fab on 2026 supply is limited, as capacity contributions will mainly start from the second half of 2027
• The global DRAM market supply-demand pattern remains tight, and the price upward trend continues

• Micron’s Tongluo fab will release capacity, and global DRAM industry supply is expected to increase in 2027
• PSMC will transform into an important link in the AI supply chain, enhancing Taiwan’s key position in the global semiconductor industry
• Micron will quickly catch up in the capacity gap through the acquisition, improving its competitive position against Samsung and SK Hynix

• The global DRAM market will shift from cyclical fluctuations to structural growth, with AI demand becoming the dominant driving force
• The strategic status of HBM will rise to the level of “oil”, promoting the entire memory industry’s revenue to approach $200 billion
• Industry competition will focus on technological innovation rather than simple capacity expansion, making it difficult for latecomers to enter the market

1. Micron’s acquisition of PSMC’s fab is a forward-looking layout to respond to the explosive demand for AI memory, using a “time for space” strategy to quickly obtain mature production capacity
2. The global DRAM market will remain in short supply in 2026, with a clear upward price trend, and suppliers will maintain a high-profit cycle
3. Micron’s technological catch-up and capacity expansion in the HBM field will reshape the global DRAM competition pattern, and the tripartite rivalry will continue

• Risk of a bubble burst in AI infrastructure investment
• A capacity surplus cycle may arrive after 2028
• Potential interference from geopolitical factors on the supply chain
