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.

Changchuan's profit surge and first dividend keep the stock in focus

First-half profit guidance up 139%-167% on tester demand Changchuan expects net profit of 900 million to 1 billion yuan for the first half, up 139%-167%, as sales of digital testers grow strongly. This is the core reason the stock is moving: the company is selling more of its main product into the AI and chip-building boom, and profit is rising fast.
This is the single biggest new fundamental driver of the stock's value.
Semiconductor equipment demand outlook strong, stock jumps 12% Industry group SEMI sees global chip-equipment sales rising 23.2% in 2026 to a record, helped by AI and memory spending. Changchuan rose over 12% in a sector rally. More demand for chip-making tools means more orders for Changchuan's testers, supporting the share price.
It shows the industry backdrop that lifts demand for Changchuan's products.
First-ever interim dividend signals confidence Changchuan announced its first interim cash dividend since listing, joining a wave of A-share companies returning cash to shareholders. A first dividend tells investors the company is confident about its cash flow and earnings, which can attract income-focused buyers and support the stock.
It is a new shareholder-return signal that can draw buyers.
Private placement shares list below issue price, interim profit confirmed New shares from a 3.13 billion yuan private placement listed on August 7 at 280.11 yuan, but the stock traded below that price, a mild negative signal. The August 28 interim report confirmed net profit of 964 million yuan, matching the earlier guidance, so the good news was already priced in.
It gives the counterweight: new share supply and a confirmed, not surprising, result.
