This diversification became a major growth engine, insulating the company from the worst memory price crashes. This strategic foresight is why we see them still posting strong numbers today.

The second major moment was the 2016 corporate consolidation. By having ChipMOS Taiwan acquire its parent company, ChipMOS TECHNOLOGIES (Bermuda) Limited, they streamlined a complex corporate structure. This move made the company more transparent and efficient for global investors, culminating in the current IMOS ticker on NASDAQ representing the core operating entity. It was a clean-up that mattered to the balance sheet.

Looking at the near-term, the company's ability to manage capital and generate profit is clear in the 2025 numbers. For the third quarter of 2025, the company reported a net profit of NT$352.2 million, reversing a loss from the previous quarter, plus they saw a significant 101% expansion in gross profit compared to Q2 2025. This kind of turnaround shows operational discipline.

Here's the quick math on their recent performance:

• October 2025 revenue hit NT$2,177.4 million (or US$70.8 million), a 22.0% increase year-over-year.
• The Board approved a capital reduction in November 2025, canceling 12,717,000 common shares, which represents 1.77% of the share capital.
• The cash balance as of Q3 2025 stood at a healthy NT$12,977.0 million.

These actions-consolidation, diversification, and prudent capital management-are the keys to understanding ChipMOS's trajectory from a joint venture to a global OSAT leader.
