TYSJ: Plans to change its stock abbreviation to "Tianyi New Materials"

TYSJ announced that the company will hold the 35th meeting of the third board of directors on May 23, 2025, to review and approve the proposal to change the company's stock abbreviation from "TYSJ" to "TYSJ New Materials," while the full name and stock code of the company remain unchanged. The reason for the change is that the company has formed four major business segments: rail transit, photovoltaic new energy, automotive, and aerospace. The stock abbreviation "TYSJ New Materials" more clearly reflects the company's business type and more accurately represents the current characteristics of the company's business development and technological innovation
