The press release is self-explanatory. The above information shall also be made available on the Company’s website www.izmoltd.com Kindly take the same on record and acknowledge. Yours faithfully, For IZMO Limited Varun Kumar A S Company Secretary and Compliance Officer Encl: As Above BUSINESS UPDATE RELEASE izmo Microsystems Unveils Silicon Photonics Modules at SEMICON India 2026 Showcasing India’s first production-ready advanced packaging capabilities for Data Center Interconnects and Quantum Infrastructure Bengaluru, India – September 15, 2026 – izmo Limited (NSE: IZMO | BSE: 532341) today announced that its semiconductor subsidiary, izmo Microsystems Pvt. Ltd., will showcase a range of production-stage silicon photonics products and advanced packaging technologies at SEMICON India 2026. The izmo Microsystems exhibit will showcase next-generation silicon photonics packaging, featuring functional products that are currently in production. These include a Quantum Random Number Generator module, a Quantum Key Distribution module packaged for Pramatra, a Thin-Film Lithium Niobate modulator packaged for CCRAFT, and advanced photonic characterization packages developed and manufactured entirely by izmo Microsystems. The showcase highlights izmo Microsystems’ unique position as the first Indian company to undertake the highly specialized packaging required to convert photonic integrated circuits into functional modules - a capability historically restricted to specialized facilities outside of India. By combining package design, precision assembly, and manufacturing under one roof, the company supports customers from initial prototyping through full commercial production. At SEMICON India, izmo Microsystems will also preview its next-generation optical transceiver portfolio, scheduled for commercial launch in 2027. Silicon photonics is an important enabling technology for AI infrastructure, high-performance computing, quantum technologies, defence, aerospace and secure communications. By transmitting data using light rather than electrical signals, it delivers the bandwidth and energy efficiency required to overcome the speed and heat-generation bottlenecks in modern advanced computing. This strategic importance is driving a global optical transceiver market, projected by Research and Markets to exceed US$30 billion by 2030. Demand is being accelerated by the expansion of AI clusters and cloud infrastructure investments in India from hyperscalers like AWS, Microsoft, and Google, creating a requirement for high-speed, energy-efficient optical connectivity. This commercial development program is bolstered by izmo Microsystems’ strategic partnership with the IIT Madras-led CPPICS Photonics Mission, supporting the translation of indigenous photonics research into commercially manufacturable products. Dinanath Soni, Director, izmo Microsystems Pvt. Ltd., said: “SEMICON India gives us an opportunity to showcase silicon photonics products that are manufactured by us and demonstrate the advanced packaging expertise we have built in India. Our strength lies in advanced package design and manufacturing, taking customers from initial development through to production. As the first Indian company to undertake silicon photonics packaging, we are helping establish a domestic capability with applications across AI, high-performance computing, quantum technologies, defence and secure communications. This progress reflects the work of our engineering teams and our collaboration with IIT Madras through CPPICS. Our forthcoming optical transceiver portfolio will build on this expertise to address growing demand in India and international markets.” Through its participation at SEMICON India 2026, izmo Microsystems aims to cement India’s emerging capabilities in advanced packaging and strengthen its engagement with customers, research institutions, and strategic partners.
