iST stated that driven by the continuous demand for AI high-speed transmission, the company delivered a stellar performance for 2025. Consolidated revenue reached the NT$4.843 billion milestone, setting a historic record high. Full-year operating net profit stood at NT$353 million, with net profit attributable to the parent reaching NT$367 million and EPS at NT$4.81. Although 2025 H2 profitability fluctuated due to front-loaded R&D expenses for strategic positioning and capital expansion, the company’s overall operational health remains robust, demonstrating strong market resilience.
Regarding Q4 performance, iST pointed out that gross profit reached NT$315 million, achieving both QoQ and YoY growth. This indicates that the product mix continues to optimize under the influx of high-end verification orders such as AI, driving steady growth in gross profit.
iST explained that while annual revenue hit a record high, profitability did not rise proportionally due to two temporary strategic factors:
First, the strategic deployment of next-generation technologies. In anticipation of the 2026 surge in 2nm ALD new material verification and the mass production of CPO (Co-Packaged Optics) Silicon Photonics, iST proactively expanded its R&D capabilities and facilities throughout 2025. While these front-loaded investments led to higher depreciation and R&D expenses—temporarily weighing on short-term profitability—they serve as the essential cornerstone for securing iST’s future technical leadership.
Secondly, the optimization of capital structure. iST completed a capital increase in Q4 2025 to bolster working capital and refine its financial health. Although the expanded share base resulted in a temporary dilution of EPS, iST emphasizes that this move is a strategic step to sharpen its global competitiveness on the “International Stage.” While this causes a mathematical impact in the short term, it is designed to drive superior long-term shareholder value.
To accelerate subsidiary Prosperity Power Technology Inc. (ProPowertek) entry into capital markets, iST’s Board approved a plan to divest shares and waive participation in ProPowertek ‘s capital increase, inviting strategyic investors. iST’s direct and indirect shareholding in ProPowertek will adjust from 74.58% to 36.83%. This adjustment signifies ProPowertek’s operational maturity and allows iST to focus on its core verification business while both entities maximize group value through resource integration.
Looking ahead to 2026, iST is confident. Growth will be driven by three core engines: 2nm Advanced Processes, AI High-Performance Computing (HPC), and Silicon Photonics. As leading foundries commence 2nm mass production, iST has secured its position in ALD technology and verification analysis. Simultaneously, iST has captured key ASIC verification orders from global CSP giants. With the Silicon Photonics CPO platform developed in collaboration with Enlitech, significant revenue contributions are expected in 2026. Following the strategic consolidation in 2025, iST expects to return to a high-growth trajectory in 2026.
