iST Reports November 2025 Revenue of NT$401 Million

Hsinchu, Taiwan–December 10, 2025 – Integrated Service Technology Inc. (iST, TWSE:3289), a leading provider of semiconductor verification and analysis services, today reported consolidated revenue of NT$401 million for November 2025, representing an 7.43% increase from a year earlier and an 1.92% rise month over month. Revenue for the first eleven months reached NT$4.406 billion, up 10.87% year on year, underscoring the company’s solid and sustained growth trajectory.

As global AI servers, data centers, and advanced packaging technologies enter a new acceleration cycle, market demand for new materials verification, electro-optical integrated measurements, and high-speed signal testing continues to rise. iST has been strategically expanding three emerging service areas—ALD material selection and thin-film verification, silicon photonics validation, and AI device reliability testing—which are expected to become new growth engines for future operations.

Global investment in AI servers, data-center infrastructure, and advanced packaging technologies continues to accelerate, driving stronger demand for new-material qualification, optoelectronic integration testing, and high-speed signal analysis. In response, iST is building momentum across three strategic service pillars—ALD (Atomic Layer Deposition) novel material selection and thin-film validation service, silicon photonics testing, and AI-related verification—positioning these as key engines for future expansion.

iST said, the company recently introduced ALD material selection and validation services tailored for the sub-2nm technology generation. The comprehensive offering—from material screening and deposition process evaluation to nanoscale thin-film characterization—enables customers to verify structure, interfaces, and quality early in the development cycle, thereby reducing production risks and improving time-to-market. Inquiry volumes continued to rise this month, signaling the industry’s accelerating shift toward next-generation materials.

iST pointed, demand for silicon photonics and CPO (Co-Packaged Optics) validation also showed significant growth in November. In response to the rapidly rising need for 800G/1.6T optical modules and optical-electrical co-packaging driven by AI servers, data center and HPC architectures are rapidly pushing optical communication toward higher bandwidth and better energy efficiency, accelerating the development of next-generation electro-optical integration.

As engineering challenges shift from traditional electronic signals to the complexities of optical-path quality, issues such as coupling loss, waveguide cracks, scattering, and absorption have become critical barriers that impact optical-path stability and packaging yield—key factors limiting the mass production of silicon photonics products.

To help customers identify risks earlier in R&D and before mass production, iST has partnered with Enlitech, Taiwan’s leading optical measurement equipment provider. Leveraging the complementary strengths of “iST in electronics” and “Enlitech in optics,” the companies have jointly established a comprehensive electro-optical measurement platform spanning device-level, wafer-level, and module-level validation.

Through Enlitech’s Night Jar optical inspection module, the platform can precisely reveal optical attenuation locations and anomalies, providing quantitative optical-loss data previously difficult to obtain in the industry. Combined with iST’s subsequent physical failure and structural analysis, engineers can quickly pinpoint and verify defect origins. Several domestic and international customers have recently initiated inquiries regarding this service.

In terms of sustainability performance, iST received multiple recognitions both domestically and internationally this month. At the Global Corporate Sustainability Awards (GCSA) and Taiwan Corporate Sustainability Awards (TCSA), the company earned the GCSA Bronze in Sustainability Reporting, TCSA Gold in Sustainability Reporting, TCSA Talent Development Leadership Award, and TCSA Workplace Well-being Leadership Award, demonstrating the company’s strong commitment to governance, disclosure, and employee care.

iST was also awarded the CommonWealth Magazine Talent Sustainability Award – Champion (Small Enterprises Category) and the CommonWealth ESG Award, affirming the company’s maturity in governance and sustainability practices. Additional honors include Parenting Magazine’s Family-Friendly Workplace Award – Small Enterprise Category, the Ministry of Labor’s Healthy Workforce Sustainability Leadership Award, and ranking within the Top 10% in Occupational Health & Safety Performance Disclosure, highlighting iST’s continuous efforts in talent development and workplace health.
