ChangXin Technology Seeks RMB 29.5 Billion in STAR Market IPO to Fund Chip Expansion
ChangXin Technology Group, the parent company of China's leading domestic memory chipmaker ChangXin Memory Technologies (CXMT), has had its application accepted for an initial public offering on the Shanghai STAR Market. The company plans to raise RMB 29.5 billion (US$4.07 billion), marking the second-largest fundraising effort in the board’s history, trailing only the RMB 53.2 billion (US$7.34 billion) raised by Semiconductor Manufacturing International Corp. (SMIC).
Market speculation regarding the company's valuation has reached as high as RMB 1 trillion yuan, reflecting its status as a critical component in China’s semiconductor supply chain amid a global supply crunch. The targeted fundraising underscores the capital-intensive nature of the memory sector; ChangXin noted that global rivals such as Samsung Electronics Co. and Micron Technology Inc. maintain annual capital expenditures in the tens of billions of dollars. Micron recently raised its 2026 capital expenditure forecast to US$20 billion to expand capacity.
In a significant financial disclosure, ChangXin Technology projected a turnaround from previous losses to profitability in 2025. The company stated in inquiry responses that it expects full-year net income to range between RMB 2 billion yuan and RMB 3.5 billion yuan. This shift signals to investors that its aggressive investments in capacity and research and development are beginning to yield financial returns as the memory market enters a recovery cycle.
The IPO proceeds are designated for upgrading wafer production lines, advancing DRAM technology, and funding forward-looking research. By securing substantial capital, ChangXin aims to accelerate its "leapfrog" development strategy to narrow the technological gap with international competitors while expanding its footprint in both the mobile and server markets.
Pivot to Profitability
ChangXin Technology’s financial performance has shown rapid growth, with revenue for the first nine months of 2025 surging nearly 100% year-on-year to RMB 32.08 billion yuan. This performance exceeds the company's full-year revenue for 2024, indicating that its investments are translating into sales at an accelerated pace.
The projected 2025 profit marks a recovery from a net loss of RMB 19.2 billion yuan in 2023. The company attributed previous losses to a cyclical downturn in the DRAM industry, which depressed prices and forced significant inventory writedowns totaling RMB 11.5 billion yuan.
Looking ahead, ChangXin management expressed optimism for steady profitability in 2026, contingent on average selling prices remaining at September 2025 levels and continued production volume growth. The company cites a "super cycle" in the memory market and improved yields as key drivers for this positive outlook.
Closing the Technology Gap
Approximately RMB 13 billion yuan—more than 44% of the total funds raised—will be allocated to DRAM technology upgrades. ChangXin employs a "leapfrog research and development" strategy, having completed mass production of its first through fourth-generation technology platforms.
Despite this progress, a gap remains between ChangXin and global leaders. Mainstream international manufacturers are currently utilizing the 1b (fifth-generation 10nm) process for HBM3e products and are advancing towards the 1y (sixth-generation) process. The fresh capital is intended to accelerate the iteration of next-generation processes, specifically targeting improvements in etching, thin film deposition, and cleaning technologies to bring ChangXin closer to the global cutting edge.
Market Position and Client Base
ChangXin currently ranks as the largest DRAM manufacturer in China and the fourth largest globally, following SK Hynix Inc., Samsung, and Micron. Counterpoint Research predicts that ChangXin’s DRAM shipments will grow by 50% in 2025, potentially increasing its global market share from 6% in the first quarter to 8% by the fourth quarter.
Mobile terminal products remain the company's primary revenue source. Its client list includes major smartphone manufacturers such as Xiaomi, Vivo Mobile Communication, and OPPO.
Concurrently, the company is pivoting toward the AI infrastructure market. While ChangXin has not yet achieved large-scale mass production of High Bandwidth Memory (HBM), revenue from AI-related server products—specifically high-performance DDR5—is expanding. In the first three quarters of 2025, server products accounted for nearly 10% of revenue, helping to improve overall gross margins.
Ownership and Governance
The IPO filing reveals that ChangXin Technology has no actual controller. The shareholding structure is diversified, with the largest shareholder, Qinghui Jidian (managed by founder Zhu Yiming), holding 21.67%. Other key shareholders include ChangXin Integrated (11.71%) and the National Integrated Circuit Industry Investment Fund Phase II (8.73%).
The company is also backed by strategic investors including Alibaba Group and Xiaomi. ChangXin maintains that its governance structure relies on a balance of power among shareholders and board members, noting that significant decisions require consensus and that historical voting records show a diversity of opinions among directors.
