TRANSTECH (09963) announced that it entered into a Procurement Framework Agreement with Tianjin Yinhu on January 16, 2026. Under this agreement, TRANSTECH has consented to purchase, and Tianjin Yinhu has agreed to sell, optical fiber preforms within the stipulated annual cap. The board of directors believes that sourcing optical fiber preforms from Tianjin Yinhu will enable the Group to capitalize on relevant market opportunities and aligns with its business strategy, as demonstrated in the following aspects: the Group maintains a close relationship with Tianjin Yinhu, providing an ideal foundation for negotiating more favorable commercial terms; Tianjin Yinhu offers products of exceptional quality at reasonable prices, granting it a significant competitive edge in the domestic market; amid the continuously growing market demand for optical fiber preforms, Tianjin Yinhu can guarantee a stable and reliable supply of raw materials to TRANSTECH for the duration of the contract; and TRANSTECH's former supplier of optical fiber preforms 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 existing equipment and production processes.
