iST stated that consolidated revenue for Q3 2025 reached NT$1.276 billion, up 5.95% from the previous quarter and 14.31% from the same period last year. Operating net income for Q3 2025 was NT$ 84 million, and net income attributable to the parent company reached NT$74 million, translating to EPS of NT$1.00.
For the first three quarters of 2025, iST’s consolidated revenue totaled NT$3.611 billion, an increase of 11.51% and net income attributable to the parent company reached NT$312 million, translating to EPS of NT$4.20.
The company noted that this quarter’s profitability was slightly impacted by expenses related to the expansion and R&D investments of two newly launched technology services. This is considered a “cost-first, benefit-later” stage, as both projects represent iST’s strategic investments for future growth and demonstrate its strong commitment to technological leadership.
Among them, the “2nm ALD Novel Material Validation Platform” is a newly developed service targeting the advancement of semiconductor process nodes. As leading foundries continue to adopt 3D transistor structures, demand for ALD (Atomic Layer Deposition) tools and novel materials is expected to rise rapidly, driving growth across the supply chain. iST has proactively extended its analytical capabilities to the material domain, offering a “materials-to-chip” end-to-end validation workflow covering novel material selection, film deposition, and thin-film quality evaluation. This platform enables material suppliers and foundries to accelerate novel material development and shorten time-to-market.
The second new service, “Silicon Photonics and CPO Validation Solutions,” focuses on optoelectronic integration for high-performance computing and AI server applications. By combining optical/electrical testing, reliability verification, and structural analysis—and through collaboration with optical inspection leader Enlitech—iST successfully addressed the industry’s long-standing challenge of quantifying optical loss and yield in CPO packaging, allowing customers to identify risks earlier in the design phase and improve overall yield.
iST emphasized that these two new services mark some of the most forward-looking technical investments in recent years. Although they require substantial upfront capital and R&D spending, they are expected to become key revenue and profit growth engines in the coming years.
Looking ahead, iST stated that verification demand related to AI and high-performance computing (HPC) remains a major driver of growth. This year, the company has secured validation and SLT (System Level Test) projects for high-end computing chips from global AI leaders, reinforcing iST’s strong technological edge in AI and advanced packaging while laying the foundation for continued growth into next year. As both new service platforms—ALD novel material validation and Silicon Photonics/CPO testing—are now in the expansion phase with related investments booked this year, short-term costs will temporarily rise. However, as equipment ramps up and customer qualification projects progress, contributions to revenue and profit are expected to begin in 2026.
Meanwhile, iST’s subsidiary ProPowertek, which focuses on AI power component wafer thinning technology, has also made solid progress. Partnering with major power device customers, ProPowertek has passed stringent verifications by top AI server OEMs and is now in stable mass production. Although still operating at a loss, the deficit has significantly narrowed, and iST remains confident that ProPowertek will achieve breakeven—and possibly profitability—in the near future.
Beyond its strong technological progress, iST also excelled in sustainability and talent development this quarter. The company received both the “Master Entrepreneur Award” and the “Corporate Excellence Award” at the 2025 Asia Pacific Enterprise Awards (APEA), recognizing its excellence in management, innovation, and sustainability.
Furthermore, iST was honored with three awards from HR Asia, including “Best Companies to Work for in Asia,” “Most Caring Company Award,” and “Diversity, Equity & Inclusion Award.” These accolades highlight iST’s long-term commitment to employee well-being and its dedication to building a happy, inclusive workplace.
