Samsung strike, China memory makers benefit? Analysts are optimistic about Changjiang Storage and CXMT’s growth potential in 2026

Memory manufacturing giant Samsung Electronics is mired in a strike risk. Supply shortages have sparked a wave of stockpiling in the spot market, with China’s Huaqiangbei DDR4 price quotes jumping 20% week over week. As China accelerates support for its domestic semiconductor industry, Yangtze Memory (YMTC) and CXMT are seizing the moment to expand capacity and push for their IPOs, with analysts bullish that both companies could become the most explosive investment targets this year.

Samsung labor-management negotiations break down, triggering a strike wave; global memory supply tightens

Samsung Electronics in South Korea and its union saw labor-management negotiations break down in the early hours of the 13th. More than 40k union members announced they will begin an 18-day large-scale strike on the 21st, sending further instability through the already tight global memory market.

Global demand for AI servers continues to expand at a high speed. High-bandwidth memory (HBM) and DDR5 supplies were already in a high-tension state of “producing and consuming as fast as possible.” If Samsung suspends production, it will not only directly reduce market supply, but also deal a major blow to customers’ inventory-buying confidence.

An analysis by Economic Daily suggests that the strike’s impact on market psychology could be far greater than the actual reduction in output. The knock-on effect of customers front-loading stockpiles will further amplify the price-rally trend.

China’s Huaqiangbei DDR4 quote jumps 20% in a week; Nanya and Winbond also benefit

As an important indicator and bellwether for global electronics spot component markets, Shenzhen Huaqiangbei felt this shock first. According to the latest data from China memory market research firm China Flash Market (CFM), the spot price this week for DDR4 8Gb 3200 has risen to $18, with a week-over-week increase of as much as 20%.

Meanwhile, NAND Flash wafer prices—previously declining steadily—have broadly stabilized and begun to level off. For server DDR5, 64GB RDIMM monthly gains rose 11%, and 96GB products also moved up 10% in sync, reflecting that AI server demand remains strong.

Nanya Technology (2408) and Winbond (2344), Taiwan’s largest-volume DDR4 shipment players, are also seen as able to benefit from this. As of the time of writing, both companies’ single-day stock prices rose 8.3% and 6.6%, respectively.

China accelerates semiconductor self-reliance; Yangtze Memory’s phase-three plant targets mass production by end-2026

At the same time that internal turmoil at Samsung impacts the global memory market, China is also using this “memory super cycle” to push full speed on its domestic semiconductor supply chain’s independent capability.

Yangtze Memory (YMTC), China’s largest NAND Flash manufacturer, currently has two wafer fabs with total monthly capacity of around 200k wafers. The newly built Wuhan phase-three plant is reportedly already completed and has entered equipment installation. It is expected to begin mass production by the end of 2026, with a target to reach monthly wafer capacity of 50k wafers by 2027.

Previously reported figures indicate that more than 50% of the equipment in the phase-three plant comes from domestic suppliers, including key equipment needed for chip vertical stacking. This shows that under pressure from U.S. export controls, Yangtze Memory has significantly deepened cooperation with China’s domestic equipment makers.

On product-line expansion, Yangtze Memory has also stepped out of its comfort zone in NAND Flash and officially moved into the DRAM market. It has already sent low-power DRAM (LPDDR) samples to customers, with feedback expected by year-end to serve as a basis for subsequent mass-production decisions. CXMT (Changxin Memory) is doing the same, actively expanding capacity with support from Beijing, and together with Yangtze Memory forms a dual-engine for China’s memory independent supply chain.

UBS is optimistic about market-share gains! Analysts name Yangtze Memory and CXMT as strong picks this year

According to a UBS report, Yangtze Memory’s market share in the global NAND Flash market last year reached 11.8%, tying with SanDisk. The gap to SK hynix’s 16%, Kioxia’s 15.9%, and Micron’s 13.3% has continued to narrow, while Samsung holds the lead at 30.4%. UBS predicts that Yangtze Memory’s global market share will surpass 14% in early 2027.

In response, Citrini analyst Zephyr directly pointed out: “Yangtze Memory and CXMT will be among the most explosive trading targets this year.” The rationale is that during the tailwind period of the memory super cycle, both companies benefit in parallel from Samsung’s supply shortfall, government subsidies, and the large capacity potential after rapid capacity expansion.

However, online community discussions note that in the near term, Yangtze Memory and CXMT technically are unlikely to directly threaten Samsung, SK hynix, Micron, and other Tier-1 players. They may instead first take market share from companies like SanDisk and Nanya. If current high memory prices see a correction, and combined with large-scale capacity expansion supported by China’s government subsidies, SanDisk and Nanya could be the ones hit first, facing the greatest competitive pressure.

The U.S. tightens export controls even more, but it becomes a catalyst for China’s semiconductor self-reliance

From a geopolitical perspective, the U.S. continues to escalate export controls on semiconductors to China, which in the short term will make it even harder for China to obtain advanced equipment. Maintenance for existing equipment also faces challenges. However, in the long run, this could instead accelerate China’s push for domestic equipment R&D and create an effect of “forcing self-reliance.” The fact that more than half of the equipment in Yangtze Memory’s phase-three plant has already adopted domestic suppliers is a concrete example of this trend.

With the backdrop of Samsung’s strike, the expanding global memory supply gap, and China’s full support for domestic semiconductors, the rise of Yangtze Memory and CXMT may arrive faster than outsiders expect.
