GRINM to fully own two silicon wafer units; AI demand lifts materials

AI and advanced packaging drive semiconductor material demand AI computing power and advanced packaging are boosting demand for silicon wafers and other materials. Industry experts say domestic substitution is now a necessity, with key segments moving from testing to mass supply. This lifts GRINM's sales outlook and supports its stock price.
This is the core demand driver that directly benefits GRINM as a semiconductor materials supplier.
Major asset restructuring to acquire remaining stakes in two silicon wafer firms GRINM plans to buy the remaining 71.89% of Shandong GRINM Aisi and 14.98% of Shandong GRINM Semiconductor, making them wholly owned. This simplifies the structure and boosts earnings per share. Trading resumes September 14 after a suspension.
This is the biggest company-specific event, directly affecting GRINM's ownership and future profits.
Global wafer demand strong; production lines nearly full GlobalWafers says its silicon wafer production lines are almost fully loaded and it is negotiating new long-term contracts. This signals tight supply and rising prices for wafers, which benefits GRINM as a wafer maker.
This provides concrete evidence of strong industry demand and pricing power for GRINM's products.

Shijia Photon's 2.8B yuan raise and 45% profit jump ride AI optical demand

2.8 billion yuan private placement for optical chip capacity Shijia Photon plans to raise up to 2.8 billion yuan by selling new shares, funding high-speed AWG chips, laser chips and optical interconnect parts, plus working capital. This gives the company money to expand output for AI data centers, supporting future sales and earnings growth.
It is the period's biggest company-specific capital action and directly funds growth capacity.
First-half profit up 45.3%, revenue up 50.66% First-half 2026 revenue reached 1.495 billion yuan, up 50.66%, with net profit of 315 million yuan, up 45.3%. Management said AI computing demand drove rapid data communications market growth and more orders than a year earlier, confirming the business is expanding fast.
It is the clearest evidence that AI demand is already converting into actual sales and profit.
AI computing demand outruns supply, lifting optical names Domestic AI computing demand jumped 417% year-on-year in early 2026 while supply grew only 128%, leaving high-end chips scarce and expensive. As an optical component supplier in that chain, Shijia Photon benefits from this shortage and the resulting rush to build AI infrastructure.
It explains the broad industry force pushing demand toward Shijia Photon's products.
Semiconductor supply chain rally lifts STAR-listed shares A broad semiconductor rally, helped by HBM memory demand forecasts and new AI model releases, pushed Shijia Photon up 10-12% in a single session. This reflects strong investor appetite for AI-linked chip stocks, though such sharp daily swings can reverse quickly.
It shows the market sentiment currently amplifying the stock, while noting the risk of fast reversals.
