Jointas (集泰股份; Shenzhen: 002909) disclosed zero sales of liquid-cooling silicone oil in the first half of 2026; the product remains in internal validation.

Jointas (集泰股份; Shenzhen: 002909) addressed its liquid-cooling silicone oil in a September 27 abnormal-stock-trading announcement, following two consecutive limit-up sessions reported by the source. The company said the product generated no sales in the first half of 2026.

The company’s broader new-energy business recorded RMB 28.4545 million in first-half revenue, representing 5.88% of total company revenue. That broader segment figure is not liquid-cooling silicone-oil revenue.

The silicone oil remains in internal application validation, with customer validation also required. Small-batch production can begin only after the relevant validation is completed and requirements are met.

The company warned of uncertainty around validation outcomes, small-batch production timing, customer adoption, order acquisition and eventual scaled sales. It also identified downstream policy, market demand, competition and customer-validation progress as factors affecting the broader new-energy business.
