ChipMOS Technologies Inc.. (NASDAQ:IMOS) shares climbed 6.8% in premarket trading on Tuesday after the company delivered third-quarter 2025 results that far exceeded analyst projections, showing solid revenue growth and a sharp rebound in profitability.

The semiconductor testing and packaging specialist reported earnings per ADS of $0.33, tripling the consensus forecast of $0.11, while revenue reached $201.7 million, ahead of expectations of $198.1 million. This represents a 1.2% increase year-over-year and a 7.1% sequential rise from the prior quarter.

Operational efficiency also improved, with the overall utilization rate rising to 66%, compared to 65% in Q2. The company’s gross profit more than doubled — up 101% quarter-over-quarter — supported by stronger demand and foreign exchange gains of $2.8 million, a sharp turnaround from the $22.7 million loss reported in the previous quarter.

ChipMOS reported a net free cash inflow of $50 million for the first nine months of 2025 and closed the quarter with $426 million in cash, underscoring a healthy balance sheet amid ongoing volatility in the semiconductor sector.

The upbeat results mark a notable recovery from Q2, when the company posted a net loss of $0.49 per basic ADS, largely driven by foreign exchange losses.
