Hsinchu, Taiwan – November 3, 2022 - ChipMOS TECHNOLOGIES INC. (“ChipMOS” or the “Company”) (Taiwan Stock Exchange: 8150 and NASDAQ: IMOS), an industry leading provider of outsourced semiconductor assembly and test services (“OSAT”), today reported consolidated financial results for the third quarter ended September 30, 2022, which were adversely impacted by global inflationary pressures, inventory adjustments and macro weakness. All U.S. dollar figures cited in this press release are based on the exchange rate of NT$31.78 against US$1.00 as of September 30, 2022.

All the figures were prepared in accordance with Taiwan-International Financial Reporting Standards (“Taiwan-IFRS”).

Revenue for the third quarter of 2022 was NT$5,254.0 million or US$165.3 million, a decrease of 23.3% from NT$6,851.7 million or US$215.6 million in the second quarter of 2022 and a decrease of 26.6% from NT$7,161.0 million or US$225.3 million for the same period in 2021.

Net non-operating income in third quarter of 2022 was NT$403.3 million or US$12.7 million, compared to NT$308.9 million or US$9.7 million in the second quarter of 2022, and NT$147.5 million or US$4.6 million in the third quarter of 2021. Third quarter 2022 results benefitted from foreign exchange gains of NT$74 million or US$2.3 million and the decrease of loss on valuation of financial assets at fair value through profit or loss of NT$18 million or US$0.6 million compared to the prior quarter. The increase compared to the third quarter of 2021 reflects the higher foreign exchange gains of NT$301 million or US$9.5 million and partially offset by the increase of loss on valuation of financial assets at fair value through profit or loss of NT$44 million or US$1.4 million.
