Sterlite Technologies' Rs 3,000 crore expansion signals bullish AI infrastructure growth

Sterlite Technologies experiences a surge in market confidence following a significant Rs 3,000 crore capacity expansion plan and bullish revenue forecasts driven by booming AI and data centre demand, positioning itself as a key player in AI infrastructure growth by FY29.

Sterlite Technologies won a sharp market endorsement on Friday, 4 September 2026, after pairing a Rs 3,000 crore manufacturing expansion with a far more ambitious message about where it wants to be by FY29. Shares hit the 5% upper circuit as the company said it would lift installed capacity by about half, while its Lakshya roadmap set out a target of Rs 20,000 crore in revenue and an EBITDA margin above 27% by the end of the period.

The spending plan follows a board decision taken on 3 September and is aimed at enlarging capacity at an existing manufacturing facility rather than building a new site. Sterlite said current utilisation is about 70%, expects the extra capacity to come on stream by the end of FY29 and plans to fund the project from internal accruals and, if needed, debt. It has declined to disclose the present installed base, saying that figure is commercially sensitive in a competitive market. (business-standard.com)

The backdrop is a quarter in which the company delivered the strongest set of numbers in its history. For the three months to 30 June 2026, revenue rose 87% year on year to Rs 1,910 crore and 33% from the March quarter, while profit after tax climbed to Rs 197 crore from Rs 10 crore a year earlier and Rs 59 crore in the preceding quarter. EBITDA reached Rs 397 crore, up from Rs 140 crore a year before and Rs 218 crore in Q4 FY26, taking margin to 20.8%, its highest level in nearly 20 quarters. The company also said it had become net debt-free after completing a Rs 1,500 crore qualified institutional placement. (economictimes.indiatimes.com)

Management has been explicit about what it believes is driving that shift. In the company’s July results statement, managing director Ankit Agarwal said: “Q1 FY’27 has been the strongest quarter in STL’s history.” He linked the performance to demand from hyperscalers and telecom operators buying AI-ready digital infrastructure, while the company said better product mix, operating leverage and a greater contribution from data-centre work had helped margins. Sterlite also said its intellectual-property portfolio now exceeds 785 patents and that a patent dispute win in Europe had reinforced its position in the UK and European optical-connectivity markets.

That AI and data-centre angle is central to the investment case. The company has already disclosed a multi-year contract worth $1.11 billion to supply optical connectivity products for next-generation AI data centres, and The Economic Times reported that the June quarter also included multiple hyperscaler orders worth more than $100 million for Neuralis, its data-centre connectivity suite, as well as a strategic long-haul dark-fibre micro-cable order. Financial Express, citing CLSA, said data centres accounted for 21% of first-quarter revenue, up from just 1% in FY26, a change that helps explain why investors are treating Sterlite less as a conventional telecom supplier and more as an AI-infrastructure play.

A separate agreement announced at the end of August adds more texture to that demand picture. Business Standard reported that Sterlite had signed a roughly $288 million long-term deal with a leading hyperscaler to supply high-density optical fibre cable products from calendar 2027 to 2029, with purchase orders to be released periodically. The contract includes a reciprocal risk-sharing framework with capped liabilities if either demand falls short or supply capacity is constrained, and it can be extended for a further two years by mutual consent. Financial Express also pointed to other recently secured business, including a $210 million order from an international telecom infrastructure company and a Rs 960 crore order from a domestic telecom operator.

Brokerage commentary has amplified the rally, though even bullish estimates vary depending on when they were published. Moneycontrol said CLSA retained an “Outperform” rating with a Rs 950 target price, implying about 33% upside from the 4 September trading level, while Financial Express had put the same target at 46% upside on 27 August, before the latest share surge. CLSA’s broader thesis is that Sterlite should benefit from a steep rise in fibre demand as North America’s data-centre capacity grows from 63GW to 126GW by 2030 and India’s from 1.6GW to 10GW, with the brokerage forecasting revenue and EBITDA growth of 14% to 21% a year between FY27 and FY29.

For now, the company has given investors a rare combination of near-term earnings momentum and a long-dated build-out story. Sterlite’s open order book stood at Rs 18,618 crore at the end of June, which Business Standard also described as more than $2 billion of visibility, and the company says demand is coming from cloud companies, telecom operators and enterprise customers across its global footprint. The next test is execution: whether a net debt-free company can deliver a 50% capacity increase by FY29 without eroding the margin gains that have turned a once-cyclical fibre business into a proxy for AI infrastructure spending.
