Sterlite Technologies Limited (STL) has officially informed stock exchanges about securing a major multi-year supply contract from a domestic telecom operator to deliver optical fibre cables.

According to the regulatory notice filed under Regulation 30 of the SEBI Listing Regulations, the order has been awarded by a domestic entity and carries a broad estimated consideration of approximately INR 960 crores. The contract involves a multi-year supply agreement spanning a period of 2 years (covering FY28 and FY29), which can be further extended by another 2 years on mutual agreement. The execution entails providing optical fibre cables strictly built to customer specifications.

Sterlite Technologies Limited is a leading global optical and digital solutions company specializing in advanced connectivity infrastructure, optical networking, and digital integration services. During 2025, the company made substantial headlines by successfully completing the demerger of its Global Services business to focus heavily on core optical and cloud/AI data centre architectures. It launched cutting-edge innovations such as high-density 864F micro cables for hyperscalers and advanced multi-core fibre solutions. The firm has also strengthened its global footprint with key project wins across the UK, US, Europe, and India.

Reflecting its ongoing business transformation, STL reported financial progress across its continuing business units during fiscal 2025, posting total annual revenues of INR 3,996 crores. The company’s EBITDA reached INR 452 crores, bolstered by robust demand in its enterprise connectivity and optical segments. Institutional participation has remained a focal point, with foreign portfolio investors (FPIs) and institutional entities actively adjusting stakes as the company pivots toward high-margin AI data centre and fibre-to-the-home solutions.
