**　Two consecutive daily limit-ups: Datongnan—company has limited BOPP capacitor film production capacity**

Datongnan has issued an anomaly announcement stating that due to the rise in oil prices, the prices of the company’s raw materials have seen fluctuations. Although cost pressures can be effectively passed on to downstream customers, they still have a certain impact on the company’s net profit. The company has actively taken countermeasures, striving to reduce the effects of raw-material price fluctuations on production and operations by optimizing procurement channels, negotiating with suppliers, and signing long-term cooperation agreements, among other measures. Currently, the company’s raw-material supply is stable, and its production and operating activities are proceeding normally and in an orderly manner, with no production disruption or major operating risk caused by the increase in raw-material prices. Given that the company’s BOPP capacitor film production capacity is limited, the current focus is mainly on meeting the steady demand of existing core customers; the extent of impact of the coating business extending into the industrial chain on the company’s net profit will depend on multiple factors, such as market demand, product sales prices, and cost control. Therefore, there is a certain degree of uncertainty.

After the implementation of the delisting risk warning, the company’s stock will trade on the risk warning board.

The Hubei Regulatory Bureau proposes to decide: to issue a warning to Santy Cableways and impose a fine of 10.5 million yuan; to issue a warning to the relevant responsible persons and impose a fine; to impose a fine of 11 million yuan on Ai Luming and take a lifelong ban from the securities market.

Dianhun Network: Plans to invest RMB 49.2 million to acquire 51% equity interest in Shanghai Manhun

Dianhun Network announced that the company plans to invest a total of RMB 49.2 million through equity transfer and capital increase to obtain a 51% equity interest in Shanghai Manhun Huanxin Planning & Design Co., Ltd. (abbreviated as “Shanghai Manhun”). After the transaction is completed, Shanghai Manhun will become a controlling subsidiary of the company and will be included in the company’s consolidated financial statements. Shanghai Manhun is a domestically leading enterprise in the secondary-dimension (anime/game) derivative products sector, focusing on the development, production, and sales of IP derivative products. This transaction achieves actual control over Shanghai Manhun. On the one hand, it can quickly integrate scarce IP resources and mature channel resources, advance the company’s strategic layout in the new growth track of secondary-dimension derivative products that is a key area of state cultivation, build a “games + IP derivative products” dual-engine driving model, and optimize the company’s revenue structure. On the other hand, by integrating Shanghai Manhun’s business layout in Japan and cooperative resources, it can open up a channel for the overseas deployment of IP derivative products, accelerating the international dissemination of China’s game IP.
