Sterlite Technologies shifts focus from fibre shipping to high-value data centre and AI infrastructure solutions, sparking debate on whether this marks a lasting re-rating amid extraordinary quarterly growth and a swelling order book.
Sterlite Technologies is betting that its business is no longer defined by simply shipping more fibre and cable. After a sharp improvement in margins in the June quarter, the company is presenting itself as a higher-value supplier to data centres and AI infrastructure, a shift that has quickly become the central question for investors: is this the start of a lasting re-rating, or just an unusually strong quarter?
The latest numbers suggest the transformation is real, but not yet fully proven. ICICI Direct reported that revenue in the June quarter rose 87.4% from a year earlier to Rs1,910 crore, while EBITDA climbed 184% to Rs397 crore and the margin widened to 20.8%, up from 13.7% a year earlier. Net profit came in at Rs197 crore, compared with Rs10 crore in the same quarter last year. Kotak Neo said revenue also increased 31.3% sequentially, underlining how sharply the business improved after the previous quarter.
That performance followed a stronger finish to the previous financial year. The company ended FY26 with revenue of Rs4,745 crore, EBITDA of Rs628 crore and a margin of 13.2%, according to the figures cited in the lead report. The leap in the June quarter has therefore become more than a simple earnings beat: it has opened a debate about whether Sterlite has crossed into a structurally different phase, with a more profitable mix of business than it has historically carried.
The order book is doing much of the work in supporting that argument. Cofacto said Sterlite’s order book rose to Rs18,618 crore by the end of the June quarter, up from Rs7,309 crore at the end of FY26. The company also announced a $1.11 billion multi-year contract for optical connectivity products aimed at next-generation AI data centres, alongside more than $100 million of hyperscaler orders for its Neuralis line. That is important because the business is not merely selling more of the same products; it is increasingly pitching higher-value solutions for dense, power-hungry data-centre networks.
According to the company’s own commentary, the Data Centre segment accounted for 21% of revenue in the June quarter, up from 1% in FY26, and management has indicated that this share could rise sharply over the current financial year. The lead report said the enterprise and data-centre business made up 19% of revenue in FY26 and that management had been aiming for 30% in FY27. In the earnings call transcript published by StockAnalysis, the group chief financial officer said the margin target had been revised upwards to 23%, while also pointing to a possible 50% revenue contribution from data centres this fiscal year. Taken together, those figures show how quickly the company is trying to reposition itself around faster-growing infrastructure spending.
The valuation debate, however, remains severe. With a market capitalisation of about Rs50,223 crore, the stock was trading at around 207 times consolidated earnings on the lead report’s figures, a level that leaves very little room for disappointment. The company’s annual profit in FY26 was only Rs56 crore, but if the June quarter’s Rs197 crore profit were repeated across a full year, the implied run-rate would be much higher. Even then, the shares would still command a demanding multiple, which is why investors are focusing less on one quarter and more on whether the new margin profile can be repeated.
Balance-sheet strength gives Sterlite some breathing room. Cofacto reported that the company raised Rs1,500 crore through a qualified institutional placement after the quarter, helping it move to a net debt-free position. That reduces execution risk and gives management more flexibility to deliver on the enlarged order book. Still, the market will eventually care less about promises and more about conversion: how much of that pipeline becomes revenue, how much of it stays high margin, and whether the company can protect returns as the mix shifts.
For now, the story is compelling but unfinished. The June quarter showed that Sterlite can earn more from each rupee of sales than it could in the past, helped by product mix, operating leverage and a larger contribution from data centres. The next few quarters will show whether that is the new normal or simply the most favourable stretch the company has had in years.
