GigaDevice Semiconductor’s shares soar as the company benefits from a global memory supercycle, strong earnings forecasts, and investor optimism driven by China’s push for technological autonomy.
GigaDevice Semiconductor’s shares rose sharply on Monday, extending a rally that has already made the stock one of the strongest performers in China’s chip sector this year. The Shanghai-listed shares closed at 444 yuan, after trading on heavy volume and touching an intraday high of 444 yuan, as investors continued to price in tight memory-chip supply and a strong first-half earnings update.
The move came against a broader backdrop of investor enthusiasm for Chinese semiconductor names tied to artificial intelligence and domestic supply-chain substitution. The South China Morning Post has noted that GigaDevice and Montage Technology have benefited from the global memory supercycle and from Beijing’s push for greater technological self-sufficiency, while also attracting additional attention through their Hong Kong listings.
At the operational level, the company remains centred on flash memory, microcontrollers, sensors and analogue chips. It is best known for NOR Flash and SLC NAND, and it has built a sizeable position in China’s general-purpose MCU market. Industry analysts say the current pricing environment has favoured suppliers in mature-node memory categories because large global manufacturers have redirected capacity towards high-bandwidth memory and advanced 3D NAND for AI data centres.
That shift has created a supply gap that has supported both prices and volumes for GigaDevice, according to TrendForce. The research group said in April that the company had already reported 2025 revenue above 9 billion yuan for the first time, and that the wider market reallocation towards advanced nodes was leaving room for niche players to benefit in the short term.
The company’s own guidance, issued in early July, pointed to a dramatic rise in profit for the first half of 2026. It forecast revenue of about 11.5 billion yuan and net profit attributable to shareholders of roughly 6.9 billion yuan, alongside a strong contribution from its storage business and steady microcontroller shipments. The projection also included fair-value gains on securities investments, underscoring that not all of the expected uplift is purely operational.
Those expectations followed a strong first quarter, when revenue reached 4.188 billion yuan and net profit climbed to 1.46 billion yuan, while gross margin improved materially. Full-year 2025 revenue had already risen to 9.203 billion yuan, with profit up nearly 50%, according to the company’s reported results. Market commentary from Hong Kong and mainland sources suggests investors are now waiting for the formal half-year figures, which are due in mid to late August, to test whether the rally is supported by continued earnings momentum.
