Sinosun Tech Gets New Owner and AI-Server Repair Acquisition

New controlling shareholder takes over at a premium Xinjiang Chaojun sold its entire 14.18% stake to Jingheheng for 539 million yuan, about 11.31 yuan per share — well above the pre-suspension close of 8.87 yuan. Jingheheng becomes controlling shareholder and Qu Jialin the actual controller. A buyer paying up signals confidence and resets the ownership story.
This is the core completed control change that directly drives the stock's re-rating.
Cross-border move into AI server repair Sinosun plans to buy Bainei Technology via new shares at 6.07 yuan plus cash. Bainei repairs and maintains high-end AI computing equipment — a hot area. This gives the loss-making anti-counterfeiting firm a new growth story and ties it to AI demand, which investors often reward.
The acquisition is the new business catalyst that explains why the stock is moving beyond the control change.
Four years of losses and an unproven pivot Sinosun lost money from 2022 to 2025, with 2025 revenue of only 128 million yuan and a net loss of 18.2 million yuan. Bainei was only set up in December 2024, and the deal is cross-border. The new business is unproven, so the turnaround could fail or take years.
This is the real counterweight: the company's weak financials and the risk that the new business does not deliver.
Same person controls both sides of the deal Qu Jialin is the ultimate controller of both Jingheheng (the buyer) and the Bainei seller. That makes the transactions related-party deals, raising questions about pricing fairness and whether the acquisition truly brings outside value. It could help or hurt depending on how investors judge the terms.
This governance detail shapes how much investors trust the deal and is a key swing factor for the stock.

Fullhan Micro's profit surge and AI-ISP demand drive the story

H1 profit forecast surges over tenfold on price hikes and AI-ISP demand Fullhan Micro expects H1 2026 net profit of 270-350 million yuan, up 1,072%-1,420% year-on-year, with record Q2 revenue and profit. The company raised product prices amid sharply higher storage prices, and all three business segments grew in both volume and price, with positive feedback for its AI-ISP chips. This directly boosts earnings and investor confidence in the stock.
This is the core new fundamental driver behind the stock's move, showing massive profit growth and pricing power.
Interim report confirms 350 million yuan net profit, but cash flow turns negative The actual H1 2026 interim report showed revenue of 1.463 billion yuan and net profit of 350 million yuan, at the top end of the forecast. However, operating cash flow was negative 86.69 million yuan, down 124% year-on-year, a real counterweight. The strong profit supports the stock, but the cash flow weakness is a caution flag for investors.
It confirms the profit surge with actual numbers while also revealing a negative cash flow that could temper enthusiasm.
Subsidiary brings in Hanlian Fund, diluting Fullhan's stake but keeping control Fullhan's subsidiary Xinhang Zhixing will receive 88 million yuan from Hanlian Fund, diluting Fullhan's ownership from 71.43% to 55.71% while retaining control. The cash injection supports the subsidiary's growth, but the dilution slightly reduces Fullhan's share of future profits. The market impact is ambiguous, leaning neutral to slightly positive.
This is a new capital move that affects Fullhan's ownership and future earnings share, with mixed implications.
