ChipMOS TECHNOLOGIES INC. reports 2025 consolidated results under both Taiwan IFRSs and IFRSs as issued by the IASB, highlighting differences caused by tax and accounting treatments. Under Taiwan IFRSs, net profit attributable to equity holders was NT$495,117 thousand, with basic and diluted EPS of NT$0.70 and NT$0.69.
