Buyback and dividend support, but 135M yuan lawsuit clouds outlook

Chairman proposes buyback and interim dividend The chairman proposed a 10-20 million yuan share buyback and a 0.2 yuan per 10 shares interim dividend. These moves signal confidence and return cash to shareholders, which can support the stock price by reducing shares outstanding and attracting income-focused investors.
This is the first news of capital return actions that directly boost investor sentiment and support the stock price.
H1 profit jumps 64% on higher revenue First-half net profit rose 64.22% year-on-year to 13.67 million yuan, with revenue up 32.83%. Strong earnings growth shows the business is expanding, which typically lifts the stock price as investors expect continued profitability.
This is the first report of actual financial results, a key fundamental driver of the stock price.
Board approves buyback at up to 8 yuan per share The board approved a buyback of 10-20 million yuan at a maximum price of 8 yuan per share, for employee incentives. This puts a floor under the stock price and shows management believes shares are undervalued, which can attract buyers.
This is the formal approval of the buyback, a concrete step that reinforces the earlier proposal and supports the stock.
Subsidiary sued for 135 million yuan A wholly owned subsidiary faces a 135 million yuan construction contract lawsuit. The amount is large relative to the company's 13.67 million yuan half-year profit, creating uncertainty and potential financial liability that could weigh on the stock price.
This is a new legal risk that could hurt the company's finances and investor confidence, a clear counterweight to the positive news.

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.
