1. What Is CXMT?

ChangXin Memory Technologies ($CXMT) is China's only large-scale integrated DRAM designer and manufacturer. DRAM (Dynamic Random-Access Memory) is the type of volatile memory used to temporarily store data being processed by smartphones, personal computers, and servers. Alongside NAND flash, DRAM forms one of the two core pillars of the global memory industry.

The company was founded in 2016 in Hefei, Anhui Province, originally under the name Project 506, an initiative launched by the Hefei municipal government. The project received substantial backing from the local industrial investment fund, with an initial commitment of approximately US$7.2 billion for its manufacturing facilities. During its early development, the company was also known as Innotron and Ruili Integrated Circuit. Today, its headquarters remain in Hefei, while it operates three 12-inch wafer fabrication plants across Hefei and Beijing.

The company is led by Zhu Yiming, a graduate of Tsinghua University and the founder of GigaDevice, China's leading NOR flash manufacturer that went public in 2016. In 2018, Zhu took over as Chairman and CEO of CXMT, publicly pledging not to receive a salary until the company became profitable. He continues to lead both companies simultaneously.

Together with YMTC, China's leading NAND flash producer, CXMT is widely regarded as one of the country's two strategic memory champions, representing the two most critical segments of China's semiconductor self-sufficiency ambitions.

CXMT deserves close attention because DRAM had long been one of the largest missing pieces in China's semiconductor industry. For more than three decades, almost no new DRAM manufacturer had successfully established itself globally. The market has been dominated by Samsung, SK hynix, and Micron, which collectively control more than 90% of global DRAM market share. As the world's largest importer of semiconductor chips, China's ability to establish a domestic DRAM producer of meaningful scale carries enormous strategic significance.

2. Growth Journey and Product Portfolio

CXMT took only nine years to grow from a startup into the world's fourth-largest DRAM manufacturer.

In 2019, the company successfully shipped China's first domestically developed 8Gb DDR4 DRAM chip, a milestone widely regarded as the moment China's DRAM industry moved "from zero to one."

In November 2023, CXMT introduced China's first domestically developed LPDDR5 chip, paving the way for its expansion into the mid-range and premium smartphone memory markets.

The year 2025 marked another major milestone as DDR5 entered commercial shipments while LPDDR5X moved into mass production.

CXMT's global market share expanded rapidly from 3.97% in Q2 2025 to 7.67% in Q4 2025, nearly doubling within just six months. This represents one of the fastest market share gains ever recorded in the DRAM industry during a major growth cycle.

Its current product portfolio includes:

DDR5 (servers and PCs): Commercial shipments began in early 2025 using the G4 process platform, offering speeds of up to 8000 Mbps and capacities reaching 24Gb.
LPDDR5X (premium smartphones): Entered mass production in 2025, delivering speeds of up to 10,667 Mbps, approximately 66% faster than the previous generation.
LPDDR5 / LPDDR4X (mainstream smartphones): Already in mass production and contributed roughly 70% of first-half 2025 revenue.
DDR4 (legacy generation): Production phase-out was announced in Q3 2025, with complete discontinuation expected by mid-2026 as manufacturing capacity shifts toward DDR5.
HBM2 / HBM2E (AI accelerators): Sampling began during the first half of 2025, with mass production targeted for 2026.
HBM3 (high-end AI memory): Mass production is planned for late 2026, targeting approximately 60,000 wafers per month, representing around 20% of the company's total manufacturing capacity.

CXMT is executing an aggressive product upgrade strategy by gradually phasing out lower-margin DDR4 products, prioritizing DDR5 and LPDDR5X, while accelerating its expansion into HBM, the highest-margin segment of the AI memory market. Supported by this product transition and a sharp rise in average selling prices, revenue from the company's DDR product line increased by 515% during 2025.

On the manufacturing side, CXMT has successfully commercialized four process generations, ranging from G1 to G4.

Its latest G4 platform is based on an approximately 16nm-class process, reducing die size by roughly 20% compared with the previous G3 (~18nm) generation.

By comparison, the industry's leading manufacturers are already producing sixth-generation 10nm-class (1-gamma) DRAM, typically around 11-12nm, with some products utilizing EUV lithography. This places CXMT approximately two to three technology generations behind the industry's global leaders.

Manufacturing capacity has expanded dramatically over the past several years:

Approximately 20,000 wafers per month in 2019.
Around 200,000 wafers per month by the end of 2024.
Approximately 240,000 wafers per month by the end of 2025.
A target of 300,000 wafers per month in 2026.

This production scale positions CXMT as the world's fourth-largest DRAM manufacturer by capacity.

The company's major customers include Alibaba Cloud, Tencent, ByteDance, Lenovo, Xiaomi, Honor, OPPO, vivo, and Transsion. Meanwhile, its DDR5 server memory products are currently undergoing qualification with several of China's leading cloud service providers.

3. Financial Performance and IPO Plan

CXMT has followed a rare financial trajectory, recording losses for nine consecutive years before delivering an explosive turnaround thanks to the memory cycle. Revenue increased from RMB 8.29 billion in 2022 to RMB 9.09 billion in 2023, RMB 24.18 billion in 2024, and RMB 61.80 billion (approximately US$9 billion) in 2025. The company also reported its first-ever annual net profit of RMB 1.88 billion.

The biggest highlight came in Q1 2026. Revenue reached RMB 50.80 billion, up 719% year over year, while net profit attributable to shareholders surged to RMB 24.76 billion. Profit from a single quarter exceeded more than twice the company's total net profit for the whole of 2025. Operating cash flow reached RMB 42.57 billion. Management forecasts first-half 2026 revenue of RMB 110 to 120 billion, with net profit expected to range between RMB 50 and 57 billion.

Gross margin also improved dramatically, rising from negative 112.71% in 2023 to 40.99% in 2025, slightly surpassing Samsung's semiconductor division during the same period. This improvement was driven by two major factors: a higher-value product mix through the transition to DDR5 and LPDDR5X, and the sharp recovery in DRAM prices during the current upcycle.

CXMT's fundraising history demonstrates strong backing from both the Chinese government and major technology companies. Its latest funding round in June 2025 included participation from Alibaba Cloud at a valuation of RMB 158.4 billion. Other investors include the National Integrated Circuit Industry Investment Fund Phase II (Big Fund II) with an 8.73% stake, Anhui provincial investment funds, Tencent, Xiaomi, and GigaDevice.

STAR Market IPO Plan:

July 2024: IPO guidance filing submitted.
October 2025: Guidance process completed.
December 30, 2025: Application accepted by the Shanghai Stock Exchange under its accelerated pre-review mechanism.
May 27, 2026: Listing committee approval obtained and registration submitted on the same day.
Target fundraising: Up to RMB 29.5 billion (approximately US$4.3 billion) through the issuance of up to 10.622 billion shares, representing at least 10% of the company's post-listing equity.

The IPO proceeds will be allocated as follows:

RMB 7.5 billion for fab upgrades.

RMB 13 billion for next-generation DRAM technology development.

RMB 9 billion for future research and development.

This is expected to become the largest mainland China IPO since 2022 and the second-largest listing in STAR Market history after SMIC. Some market participants have speculated that CXMT's post-listing valuation could reach RMB 2 to 3 trillion. However, such estimates represent a substantial premium over its latest private valuation of RMB 158.4 billion and should therefore be viewed with caution.

4. The DRAM Industry and the AI Opportunity

The DRAM industry has one of the longest and most competitive histories in semiconductors. It originated in the United States during the 1970s, shifted to Japan in the 1980s, and has been dominated by South Korea since the 1990s. Every downturn eliminated numerous manufacturers, eventually leaving only Samsung, SK hynix, and Micron controlling more than 90% of the global market for decades.

DRAM is a highly standardized commodity whose pricing fluctuates significantly based on supply and demand. Following the 2017 to 2018 supercycle, the industry experienced severe downturns in both 2019 and 2023. Beginning in 2024, however, explosive AI data center demand fundamentally changed market dynamics. Leading manufacturers redirected production capacity toward HBM and high-end server DRAM, resulting in shortages of conventional DRAM products. TrendForce estimates that AI applications will consume approximately 20% of global DRAM wafer capacity by 2026.

Global DRAM industry revenue reached approximately US$165 billion in 2025, representing a 73% increase from the previous year. The broader memory market, including both DRAM and NAND, is projected to reach US$551.6 billion in 2026 before potentially peaking at US$842.7 billion in 2027. Memory revenue in 2026 is expected to exceed twice the revenue of the global foundry industry, which is forecast at US$218.7 billion. This would mark the first time in semiconductor history that the memory sector generates such a large revenue advantage.

CXMT stands out as one of the biggest beneficiaries of the conventional DRAM shortage created by competitors shifting their resources toward AI memory products. At the same time, China's semiconductor import substitution strategy provides a powerful policy tailwind, allowing CXMT to compete with structural support that extends beyond a normal industry cycle.

5. Competitive Landscape

According to Q4 2025 data, the global DRAM revenue market share was distributed as follows:

Samsung (South Korea): 36.0%
SK hynix (South Korea): 32.1%
Micron (United States): 22.4%
CXMT (China): 7.67%
Taiwanese manufacturers (Nanya, Winbond, etc.): Approximately 2%

CXMT has effectively pushed smaller DRAM manufacturers into marginal positions and established itself as the industry's legitimate fourth major player. However, its revenue remains only around one-third of Micron's, while its manufacturing technology still trails leading competitors by approximately two to three generations.

SK hynix has emerged as the biggest winner of the current memory cycle thanks to its dominant position in HBM. Micron, meanwhile, faced setbacks following China's cybersecurity review in 2023, causing part of domestic demand to shift toward CXMT. Fujian Jinhua serves as a cautionary example after being prosecuted by the United States and losing access to advanced manufacturing equipment. YMTC, China's leading NAND producer and CXMT's strategic counterpart, is also preparing for its own STAR Market listing.

Importantly, CXMT does not need to surpass the global leaders worldwide. Simply replacing imported DRAM within China, the world's largest DRAM consumption market, would provide enough demand to sustain a company several times larger than it is today.
