Tianjin Jiuri New Materials Co., Ltd. was founded in 1998. The Company has a registered capital of RMB 161,227,251 and total assets of RMB 4.145 billion. It focuses on the R&D, production, and sales of photocurable materials such as photoinitiators and monomers, as well as semiconductor chemical materials including photoresists and photosensitizers. The Company is listed on the STAR Market of the Shanghai Stock Exchange (stock abbreviation: Jiuri New Materials, stock code: 688199.SH).

The Company’s headquarters is equipped with a modern R&D center, which hosts a “National Enterprise Technology Center,” a “National Postdoctoral Research Workstation,” and the “Tianjin Photoinitiator Technology Engineering Center.” With strong technical expertise and research capabilities, the Company has established the “Nankai University – Jiuri New Materials Joint Research Institute” in collaboration with Nankai University, as well as the “Advanced Photosensitive Materials Joint R&D Center” with the Greater Bay Area Innovation Institute of Hunan University. These initiatives provide robust support for the Company’s continuous innovation and the translation of research results into practical applications. As of June 30, 2026, the Company and its subsidiaries hold a number of patented and non‑patented technologies, including 141 invention patents and 52 utility model patents. The Company has led the formulation of 5 industry standards for photoinitiators and participated in the remaining 7 (out of a total of 12 industry standards in the photoinitiator sector). In addition, the Company has participated in the development of 5 national standards, of which 5 pertain to the photosensitive materials industry and 1 to feed additives, and has also contributed to several group standards.

The Company has been selected to lead a number of national and provincial or ministerial key projects, and has won many honors and titles, such as National Key New Products, Chinese Patent Excellence Award, Tianjin Patent Gold Award, Tianjin Science and Technology Progress Award, Tianjin Famous Trademarks, and Tianjin Specialized and Sophisticated Products. The Company has also been certified as a national high-tech enterprise, a national manufacturing single champion demonstration enterprise，a state service-oriented manufacture leading enterprise，a national specialized and sophisticated enterprise (little giant), and a leading enterprise of strategic emerging industries in Tianjin.

The Company has multiple subsidiaries, including Shandong Jiuri, Hunan Jiuri, Inner Mongolia Jiuri, Jiurui Xianghe, Jiuyuan Technology, Hong Kong Jiuri, Jiuri Semiconductor, Dajing Information, and Dajing New Materials, among others. Among these, Hunan Jiuri, Inner Mongolia Jiuri, and Shandong Jiuri serve as production bases for photocurable materials. Specifically, Jiuri Semiconductor functions as the Company’s R&D platform for semiconductor chemical materials such as photoresist and photosensitizer, while Dajing Information and Dajing New Materials serve as production bases for such materials.

Adhering to a global business strategy, the Company focuses on photocuring materials as its core business while prioritizing semiconductor materials as a key growth area. Since 2020, we have strategically expanded into photoresist and related raw materials through acquisitions and investments. In 2021, we established a dedicated R&D platform for semiconductor chemicals to advance photoresist and photosensitizer development. In 2022, we commenced production of a 600‑ton‑per‑year photosensitizer facility, marking a significant breakthrough in domestic supply of critical materials for g/i‑line and display photoresists. In late 2024, our 4,500‑ton‑per‑year photoresist project entered trial production. Today, we have built an integrated full‑industry chain covering the entire value chain—from photosensitizers, monomers, resins, and auxiliary reagents to finished photoresist products—for both display and semiconductor upstream sectors.
