What’s driving Sterlite Technologies’ stock price?

STL is a global leader in digital connectivity infrastructure, serving telcos, data centers, citizen networks and large enterprises. The company’s portfolio spans fiber to fiber optic cables, specialty cables and connectivity products. STL is India's No. 1 end-to-end optical manufacturer with over 8 per cent global optical fiber cable market outside of China. And with more than 30-plus years of leadership, close to almost 800 patents and 10+ zero waste manufacturing facilities worldwide, STL is truly leading the next wave of global digital infrastructure. 

STL on May 22, 2026 announced the receipt of a multiyear Product Award Letter (PAL) valued at more than $1 billion. Under this agreement, through one of its subsidiaries, STL will supply optical connectivity products to a hyperscaler for AI Data Centre build-outs. Under this agreement, STL, through its optical solutions, will support building AI data center infrastructure in the US for this hyperscaler.  READ | Auto stocks to buy: Analysts back Maruti, TVS, M&M, TaMo after May sales 

India data center expansion is emerging as one of the most compelling structural tailwinds of optical fiber, and STL is uniquely positioned to capture it, the management said in Q4 earnings conference call. 

Installed capacity is set to grow to 5x from 1.4 gigawatts in 2025 to 8 gigawatts by 2030. What makes this cycle particularly powerful is the breadth of commitment that hyperscalers like Google and Microsoft are deploying tens of billions of dollars. Indian conglomerates like Adani and Reliance are anchoring gigawatt campuses, and even domestic majors like TCS are laying out long term capacity plans, STL said. 

“This is a diversified and resilient demand base. A supportive policy environment, state incentives, power availability and benefits and tax holidays extending 2047 is further derisking and accelerating the build-out. Every dollar of data center capex has a direct multiplier of fiber intensity across DCI, metro and long-haul networks with optical cable demand projected to grow at 11 per cent compound annual growth rate (CAGR) through 2030. This is not a cyclical uptick. It is a durable high visibility growth opportunity playing out right here in our home market in India”, the company said. 

According to CRU, global optical cable demand growth for 2026 has been upgraded to about 6.8 per cent year-on-year, following stabilization in 2025, led by mainly the North America's data center build-out and improved execution in China. Importantly, demand is now consistently outpacing domestic supply in North America, keeping the lead times tight, STL said.
