Stock extends rally in Monday’s trade

Shares of Sterlite Technologies Ltd (STLTECH) extended their sharp upward move in Monday’s session, rising 5% to an intraday high of ₹463.45. The move adds to a year-to-date surge of 352.37% in 2026, based on the stock’s rise from ₹102.45 on January 1. Market attention has been focused on a large international contract win disclosed by the company in an exchange filing. The order relates to optical connectivity products used in data centre infrastructure.

What triggered the latest move

The rally followed an announcement made last Friday that Sterlite Technologies received a Product Award Letter (PAL) from an international hyperscale partner. The PAL covers a multi-year supply of optical connectivity products. Sterlite said the total potential value of the contract over its tenure is estimated at about ₹10,622 crore, based on prevailing selling prices of the products being supplied. The supply agreement is described as running through FY29 and is linked to artificial intelligence data centre infrastructure in the United States.

Contract details disclosed by the company

Sterlite’s exchange filing said the contract will be executed over a multi-year period by the year ended March 2029. Separate contract updates also indicate supplies are slated across FY27 to FY29, consistent with the overall execution window ending in March 2029. The counterparty was described as a US-based hyperscale partner, without naming the customer. The products covered fall under optical connectivity used in high-capacity network infrastructure for data centres.

Brokerage action: CLSA raises target price

Following the order announcement, CLSA raised its target price on Sterlite Technologies by 60% to ₹655 from ₹405, while maintaining an Outperform rating. CLSA described the contract as a major validation for Sterlite’s AI data centre optical products business. The brokerage also said the deal could drive a 49% EBITDA CAGR over the coming years, as per the note referenced in market coverage. The target revision and the size of the order contributed to investor focus on the stock.
