Sterlite Technologies shares rose as much as 5 % to a 52‑week and intraday high of ₹955.35 on the National Stock Exchange on Thursday, 1 October, after the company announced a long‑term supply agreement worth $1.2 billion with an international hyperscale partner. The deal, which will span from calendar year 2026 to 2030, focuses on the allocation of optical connectivity products and is expected to generate a total potential value of approximately $1.2 billion over its tenure.

The share price climbed to ₹955.35, up 5 % from Wednesday’s closing price of ₹909.90. At about 2:50 PM the scrip traded 4.09 % higher at ₹947.10, while the intraday low had fallen to ₹84.60. The rally was driven by buying interest following the announcement of the long‑term supply agreement, which is expected to secure a steady stream of optical connectivity orders for the next five years in the coming years.

Under the long‑term supply agreement, Sterlite Technologies will supply optical connectivity products as per customer specifications, with the contract valid until December 2030. The international hyperscale partner will issue purchase orders periodically during the contract period. The agreement establishes a reciprocal risk‑sharing framework, defining mutual capped financial liabilities for both parties in case of demand or supply capacity shortfalls or failures to ensure continuity and mitigate operational risks.

In a separate regulatory filing dated September 24, Sterlite Technologies announced it had strengthened its Neuralis portfolio by launching pre‑terminated fiber trunk assemblies to power hyperscale data centres. The new assemblies range from 48F to 6912F and are a high‑density cabling portfolio purpose‑built for hyperscale and enterprise data centres, addressing an unprecedented surge in bandwidth demand driven by AI, cloud, and high‑performance computing workloads across global infrastructure projects.

Sterlite Tech’s stock has surged 15 % in the past week and 37 % over the month, with a year‑to‑date gain exceeding 826 %. The company’s market capitalisation stood at ₹48,694.09 crore as of 1 October 2026, according to NSE data. The shares have touched a year‑low of ₹84.60 and reached a 52‑week high of ₹955.35, reflecting the market’s confidence in the long‑term supply agreement and the company’s expanded fibre offerings for future growth.
