ChipMOS Q4 2025 jumps as full-year profit falls
ChipMOS TECHNOLOGIES INC. reported strong fourth quarter 2025 results but much weaker full-year profit.
Rhea-AI Filing Summary
ChipMOS TECHNOLOGIES INC. reported strong fourth quarter 2025 results but much weaker full-year profit. Q4 2025 revenue reached NT$6,521.1 million, up 6.1% quarter over quarter and 20.8% year over year, driven by surging demand for high-value memory, especially datacenter and AI applications.
Q4 gross margin improved to 14.3%, and net profit attributable to equity holders rose to NT$499.7 million, or NT$0.72 per basic common share and US$0.46 per basic ADS. For full year 2025, revenue grew 5.5% to NT$23,932.9 million, but net profit attributable to equity holders fell to NT$495.1 million from NT$1,420.0 million, mainly due to foreign exchange losses and higher losses from associates.
The company generated net free cash flow of NT$1,554.8 million and ended 2025 with cash and cash equivalents of NT$14,858.9 million. The board authorized a distribution of NT$1.23 per common share from capital surplus, pending shareholder approval at the May 2026 AGM.
Positive
- Strong Q4 2025 rebound: Revenue rose to NT$6,521.1 million, up 6.1% sequentially and 20.8% year over year, with gross margin improving to 14.3% on higher memory demand and better utilization.
- Healthy cash generation and balance sheet: Net free cash flow reached NT$1,554.8 million in 2025, and cash and cash equivalents totaled NT$14,858.9 million, supporting continued operations and shareholder returns.
- Shareholder distribution proposal: The board authorized a distribution of NT$1.23 per common share from capital surplus, pending shareholder approval at the May 2026 AGM, signaling willingness to return capital.
Negative
- Sharp full-year earnings decline: Net profit attributable to equity holders fell from NT$1,420.0 million in 2024 to NT$495.1 million in 2025, a substantial drop despite modest revenue growth.
- Adverse non-operating impacts: Results were pressured by a swing from NT$243 million in foreign exchange gains in 2024 to NT$460 million in foreign exchange losses in 2025 and higher losses from associates.
Insights
Q4 operations rebounded strongly, but full-year profit was hit by FX and associate losses.
ChipMOS shows a notable operating recovery in Q4 2025. Revenue rose to NT$6,521.1 million, up 20.8% year over year, as memory demand for datacenter and AI strengthened. Gross margin improved to 14.3%, reflecting better utilization, especially in memory.
The full-year picture is weaker. Revenue grew 5.5% to NT$23,932.9 million, but net profit attributable to equity holders dropped from NT$1,420.0 million to NT$495.1 million. Management attributes this mainly to a swing from foreign exchange gains of NT$243 million in 2024 to foreign exchange losses of NT$460 million in 2025, plus higher losses from associates.
Cash generation remains solid, with net free cash flow of NT$1,554.8 million and year-end cash and cash equivalents of NT$14,858.9 million. The proposed NT$1.23 per share distribution from capital surplus, subject to approval at the May 2026 AGM, underscores balance sheet strength despite earnings volatility.
