TRANSTECH (09963) announced that it signed a "Procurement Framework Agreement" with Tianjin Yinhu on January 16, 2026. According to the agreement, TRANSTECH agrees to purchase, and Tianjin Yinhu agrees to sell, optical fiber preforms within the stipulated annual ceiling.

The board of directors believes that procuring optical fiber preforms from Tianjin Yinhu will enable the Group to capitalize on market opportunities and aligns with the Group's business strategy, as evidenced by the following factors: the Group maintains a close relationship with Tianjin Yinhu, providing an ideal foundation for negotiating more favorable commercial terms; Tianjin Yinhu's products are of excellent quality and reasonably priced, giving them a significant competitive advantage in the domestic market; at a time of continuously growing market demand for optical fiber preforms, Tianjin Yinhu can provide a stable and reliable supply of raw materials to TRANSTECH during the contract period; and TRANSTECH's previous optical fiber preform supplier was a Japanese company that has ceased supply due to insufficient production capacity. In contrast, Tianjin Yinhu possesses similar production equipment and technology, and its products are perfectly compatible with TRANSTECH's equipment and production processes.
