The Shenzhen Stock Exchange issued a query letter to Shenzhen Weiteou New
Materials Co. after a recent sharp share rise, noting abnormal volatility on May
20 and a daily-limit up on June 4. The exchange flagged frequent roadshows from
Apr 25–May 21 (seven investor-relations records) and repeated Q&A references to
optical modules and advanced packaging. It asked the company to disclose: the
amount of solder paste required at each optical-module production stage,
corresponding unit prices and amounts, and share of module price; and for each
of the company’s main products, their application in the three production
stages, the main customers by stage, sales in the past year and in the most
recent reporting period, gross margin, and order backlog amount.
