SEWAME TECHNOLOGY STOCK TRADING SERIOUSLY ABNORMAL FLUCTUATIONS ANNOUNCEMENT, Recently, the company has noticed the spread of false rumors on the platform about the company and its subsidiaries' products "electronic hydrocarbon resins" and "LCD color photoresists", which has attracted investors' attention. The company has verified the relevant content and, in order to avoid misleading investors, now clarifies that the company's electronic-grade hydrocarbon resin products are mainly used in the M6~M8 grade high-speed copper-clad board field. The products for M9 grade or higher are currently only in the research and development stage and have not yet been mass-produced. The high-end electronic new materials industry generally has characteristics such as long customer validation cycles and difficulty in market development, resulting in significant uncertainties in business expansion. In the short term, the contribution of the company's overall performance is limited. At the current stage, the company has no plans to expand the production capacity of hydrocarbon resins. Investors are advised to pay close attention to the potential investment risks related to this matter.
