HSINCHU, Oct. 8, 2026 /PRNewswire-FirstCall/ -- ChipMOS TECHNOLOGIES INC. ("ChipMOS" or the "Company") (Taiwan Stock Exchange: 8150 andNasdaq: IMOS), an industry leading provider of outsourced semiconductor assembly and test services ("OSAT"), today reported its unaudited consolidated revenue for the month of September 2026 and for the third quarter ended September 30, 2026. All U.S. dollar figures cited in this press release are based on the exchange rate of NT$31.85 to US$1.00 as of September 30, 2026.

The Company noted its third quarter 2026 revenue represents a record high, with revenue growth driven by sustained AI-related demand outpacing available memory supply. While the Company continues to invest in footprint expansion, new capacity is being deployed to meet existing customer forecasts and long-term supply agreements, as structural supply constraints persist and demand broadens across most of the Company's memory and storage end markets.
