Guojin Securities predicts that in Q1 2026, TGCF's HVLP copper foil will continue to show a growth trend both sequentially and year-on-year.

In the first quarter of 2026, TGCF achieved revenue of 1.842 billion yuan, a year-on-year increase of 32%, with a net profit attributable to the parent company of 106 million yuan, a year-on-year increase of 2138%, and a net profit attributable to the parent company after deducting non-recurring gains and losses of 102 million yuan, a year-on-year increase of 2237%.
