Delhi: The rapid expansion of artificial intelligence, data centres and energy infrastructure in the United States is creating new opportunities for companies supplying the equipment and materials needed for these projects. The trend is also drawing attention to Indian companies such as Sterlite Technologies and Welspun Corp.
Sterlite Technologies has delivered an extraordinary stock return of around 690% over the one-year period ending October 1, 2026. Welspun Corp has also recorded significant gains during the same period. Although the two companies operate in different industries, rising demand from the US has emerged as an important growth factor for both.
Sterlite Technologies Sees Strong Data Centre Growth
Sterlite Technologies was incorporated in July 2001 and manufactures optical fibre, fibre strand, cables and connectors. The company has a market capitalisation of approximately ₹49,110 crore and accounts for around 8% of the global optical fibre cable market outside China.
The company faced pressure in its core business in previous years. Its operating margin declined from 17% in FY21 to 10% in FY25, while it reported losses in both FY24 and FY25.
However, the rapid expansion of AI-driven data centres has opened up a new growth opportunity. High-speed fibre networks are essential for transferring huge volumes of data between thousands of chips operating inside modern data centres.
Data Centre Revenue and Order Book
According to Sterlite Technologies’ June 2026 quarter figures, data centre-related revenue accounted for 21% of total revenue, compared with just 1% in FY26. North America’s contribution also increased to 54% from 39%.
During the June 2026 quarter, the company reported sales of ₹1,910 crore, EBITDA of ₹385 crore and net profit of ₹197 crore. In the corresponding quarter a year earlier, sales stood at ₹1,019 crore, EBITDA was ₹132 crore and net profit was ₹10 crore.
Sterlite secured new orders worth around ₹13,100 crore during the June 2026 quarter. Its open order book subsequently reached a record ₹18,618 crore.
In May, the company announced a product award letter worth approximately $1.11 billion from a global hyperscaler, with deliveries planned between FY27 and FY29. Later, in a BSE filing dated October 1, 2026, Sterlite disclosed a long-term supply agreement worth around $1.2 billion with a hyperscale partner, extending until December 2030.
Sterlite Stock Gains Nearly 690%
Sterlite Technologies’ shares were trading at around ₹122 in October 2025. By the market close on October 1, 2026, the stock had climbed to approximately ₹955, translating into a gain of nearly 690% in one year.
The sharp rally, however, has also pushed the company’s valuation considerably higher. Based on the provided data, Sterlite’s price-to-earnings ratio is around 208 times, compared with an industry median of approximately 59 times.
The company’s 10-year median P/E stands at 23 times, while the industry’s 10-year median is around 24 times. This indicates that valuation-related risks have increased following the substantial rise in the stock price.
Welspun Corp Gets Major US Order
Welspun Corp operates in a different segment and is among the world’s leading manufacturers of large-diameter steel pipes. Its products are used for transporting oil, gas and water over long distances.
The company has operations in India, the United States and Saudi Arabia and supplies products to more than 50 countries. It also owns the Sintex brand.
On September 25, 2026, Welspun Corp informed the BSE that its US subsidiary, Welspun Tubular LLC, had secured an order worth approximately $412.5 million, equivalent to more than ₹3,600 crore.
The company described the contract as its largest order ever in terms of volume, length and value. The pipes will be produced at its Little Rock facility in the US and supplied during FY28 and FY29.
Following the contract, Welspun Corp’s global order book reached a record $47 billion, or approximately ₹39,500 crore. In January 2026, the company’s order book was ₹23,460 crore, highlighting the sharp increase over the following nine months.
Welspun Corp Profit Jumps in Q1 FY27
Welspun Corp reported a net profit of ₹1,048 crore for the June 2026 quarter, almost 200% higher than the ₹349 crore recorded in the same quarter of the previous year.
However, the latest quarterly profit included a one-time gain of ₹548 crore from the sale of the company’s stake in its Saudi subsidiary, EPIC.
The company’s stock has also delivered strong returns across different periods. It has gained approximately 205% over one year, 560% over three years and 1,705% over five years.
