Summary of Key Points
On July 27, Changxin Technology (688825.SH) made its debut on the STAR Market, closing with a market value of 3.28 trillion yuan on its first day—surpassing Industrial and Commercial Bank of China to become the largest A-share company on that day, and trading volume exceeded 140 billion yuan, setting a new record. The company reported a significant increase in net profit for the first quarter (24.762 billion yuan in parent company earnings), which is two-thirds of its cumulative losses. However, the market is more concerned about two core issues: Will capacity expansion alleviate the shortage of general-purpose DRAM (common memory)? And in a market dominated by Samsung, SK Hynix, and Micron, can Changxin secure a fourth-place position?
There are clear differences in the approaches taken by China and the United States to develop storage chips: The U.S. focuses on "research and development barriers plus manufacturing localization" (with Micron receiving government subsidies to build domestic factories), while China relies on "absorbing technical heritage and long-term capital investment" (Changxin acquired technology from Qimonda, and Hefei's state-owned assets have provided continuous support). Changxin's capacity expansion will improve the supply of general-purpose DRAM in the medium term but may not lower prices immediately; in the field of HBM (core memory for AI servers), it is unlikely to challenge the three giants in the short term. To secure a fourth-place position, Changxin must overcome three major hurdles: price cycles, technological catch-up, and customer validation. Nevertheless, as the first large-scale DRAM manufacturer from mainland China in a decade, it has indeed added another "Chinese card" to the game board.
Detailed Analysis
1. The Rapid Rise After Listing: Not Just a Hype, but a Bet on the Future of Domestic Substitution
Changxin's 465% increase in value on its first day and market value exceeding that of ICBC may seem exaggerated, but it reflects the high expectations for domestic storage autonomy:
- Real Demand Support: China imports over $420 billion in chips annually, with a significant portion being storage chips. The emergence of Changxin means local companies no longer have to rely entirely on the three giants, providing downstream manufacturers (such as those in the smartphone and PC industries) with more options and reducing supply chain risks.
- Sign of Profitability: The first-quarter net profit of 24.7 billion yuan, although mainly due to price increases in memory, demonstrates that Changxin can be profitable—a critical breakthrough for domestically produced storage, which has long been loss-making.
- Capital Confidence: The company raised 57.9 billion yuan through listing, which will be used for technology upgrades and research and development, indicating market confidence in its ability to expand production and catch up with technology.
In short, the 3-trillion-yuan market value is a bet on the possibility that China can produce high-quality memory on its own.
2. Will Capacity Expansion Lower Memory Prices? It Depends
There are two scenarios:
- General Purpose DRAM: There is potential for price relief in the medium term, but not in the short term.
- HBM: HBM, used in AI servers, is currently beyond Changxin's reach due to high technical barriers. The three giants dominate this market.
3. Different Paths for China and the U.S. in Storage Chip Development
The global storage chip market has been monopolized by American and Korean companies for over a decade, with different strategies adopted by China and the U.S.:
- U.S.: Localizing Manufacturing with Subsidies: Micron received $6.1 billion in government subsidies to invest $250 billion in domestic factories by 2035, aiming for 40% of DRAM production in the U.S. It also holds 60,000 patents to protect its technology. However, new factories will only start producing in 2027, limiting short-term supply flexibility.
- China: Leveraging Technical Heritage and Long-Term Capital: Changxin acquired some technology from the bankrupt German company Qimonda and received significant support from Hefei's government (14.4 billion yuan out of a total investment of 18 billion yuan). China's advantages include a large domestic market and strong engineering capabilities, but it faces challenges such as accessing advanced equipment (e.g., EUV lithography machines) and needing time for customer validation.
4. Can Changxin Secure a Fourth Place?
Changxin has three key assets, but it must overcome price cycles:
- China's Large Market: With annual chip imports of $420 billion, there is room for domestic substitution.
- Technological Innovation: Changxin is researching Bonded DRAM, which could potentially bypass EUV lithography limitations and achieve near-advanced manufacturing processes. However, this is still in the research phase and has not been verified in mass production.
- Industrial Capital Support: Hefei's government and other investors have invested heavily over the past decade, providing sufficient funds for expansion.
In summary, while Changxin has made significant progress, it needs to prove its profitability and ability to sustain growth during a price cycle (e.g., 2-3 years) to secure its position in the DRAM industry.
Final Remark
Changxin's listing marks a shift from having storage chips to being competitive in this field. While China has added another player, whether it can truly establish itself as a leader depends on its ability to navigate market cycles, catch up with technology, and build strong customer relationships.
