CXMT starts G5 production. CXMT Corporation stock sits 11.34 percent below its high

CXMT Corporation (ISIN CNE100007WP2) said its fifth-generation DRAM platform entered mass production on September 20, 2026, according to Reuters. The milestone places process scale, product density and manufacturing economics at the center of the investment case for the Shanghai-listed memory-chip maker.

G5 raises chip density

Reuters reported on September 20, 2026, that CXMT's G5 platform uses an 11.95-nanometre active-area half-pitch and can produce at least 50.00 percent more gross chip dies per wafer than its fourth-generation platform. The company also introduced two 24-gigabit LPDDR5X products, each holding 50.00 percent more data than the previous equivalent products.

The comparison is meaningful for production economics, but it is not the same as a yield figure. Reuters said the die count is measured before defective units are excluded, so actual output and manufacturing efficiency still depend on final testing results.

Revenue jumps in first half

CXMT reported operating revenue of CNY 150.31 billion in the first half of 2026, up 873.64 percent from the first half of 2025, while net profit attributable to shareholders reached CNY 77.61 billion. Global Times linked the increase to tight DRAM supply, higher product prices and stronger sales volume.

The scale of the comparison changes how G5 is read. A 873.64 percent revenue increase provides financial momentum, while the 50.00 percent wafer-die improvement offers an operating metric that could support cost competitiveness if CXMT converts the process claim into reliable shipment volumes.

Stock remains below yearly high

CXMT was last at CNY 54.79 on the Shanghai Stock Exchange on September 30, 2026 at 3:00 p.m. CST, versus a prior close of CNY 55.55. The 52-week range was CNY 38.11 to CNY 61.80, placing the latest quoted price 11.34 percent below the high.

The company identifies itself as SSE 688825 and describes its business as DRAM design, research and development, manufacturing and sales. Its product portfolio includes LPDDR6, DDR5 and LPDDR5X, while the September 20 G5 announcement adds a concrete manufacturing milestone to that existing product strategy.
