STL Rides AI Wave with Record Growth and Fiber Optic Innovation

MUMBAI, India – April 29, 2026 – Sterlite Technologies Ltd. (STL) has announced a transformative fiscal year, marked by robust financial growth and a strategic pivot that firmly positions it at the heart of the global artificial intelligence boom. The digital infrastructure provider reported a formidable 18.8% year-over-year revenue increase to INR 4,745 Cr for FY26, but the headline figure is a staggering 110% surge in order intake, signaling a powerful growth trajectory fueled by the voracious data demands of AI.

This record performance, which includes a sixth consecutive quarter of improving EBITDA margins, has culminated in an open order book of INR 7,309 Cr. This robust pipeline, underpinned by major deals in North America, Europe, and India, underscores the market's confidence in STL's ability to deliver the foundational connectivity required for next-generation data centres and telecom networks.

Powering the AI Revolution

STL's impressive results are not happening in a vacuum. The company is strategically capitalizing on the explosive growth of the global AI data centre market, an industry projected to expand at a compound annual growth rate (CAGR) of over 25% through the next decade. As businesses and cloud providers race to deploy powerful GPU-based systems for AI workloads, the underlying physical infrastructure—specifically, the high-speed, low-latency optical connectivity—has become a critical bottleneck and a massive market opportunity.

In response, STL has sharpened its focus, leveraging its end-to-end capabilities to emerge as a key enabler in this space. A cornerstone of this strategy is the launch of Neuralis, a purpose-built connectivity suite designed specifically for AI data centres. This solution addresses the unique challenge of wiring thousands of GPUs together in dense configurations, requiring ultra-high-density cabling that can handle immense data traffic with minimal delay. By architecting solutions for GPU-intensive workloads, STL is moving beyond being a simple component supplier to becoming an integrated partner in building the world's AI factories.

Redefining Connectivity with Next-Gen Fiber

At the core of STL's strategy is a relentless drive for innovation in optical physics. The company made significant waves in FY26 by introducing India's first Hollow Core Fibre (HCF) cable. This groundbreaking technology replaces the traditional solid glass core of an optical fiber with an air-filled channel. Because light travels nearly 46% faster through air than glass, HCF drastically reduces latency—a critical metric for high-frequency trading, interconnected data centres, and real-time AI inference.

While still an emerging technology, HCF is gaining traction globally, with major network operators beginning deployments for latency-sensitive routes. By developing this capability in-house, STL not only establishes itself as a deep-tech leader but also gains a significant competitive advantage in the race to build the next generation of the internet.

Further bolstering its innovation portfolio, the company launched a 4-core Multi-Core Fiber (MCF) cable for the UK market, which multiplies the data capacity of a single fiber strand, and CONCAT, a pre-connectorized, plug-and-play solution that slashes installation time and costs. The industry has taken note; both CONCAT and the MCF solution received top honors at the prestigious Lightwave Innovation Reviews during the OFC 2026 conference, affirming their technical excellence and market relevance.

A Financial Turnaround Fueled by Record Orders

The company's strategic initiatives are translating into a strong financial resurgence. FY26 revenue hit INR 4,745 Cr, while EBITDA climbed to INR 628 Cr. The final quarter was particularly strong, with record quarterly revenue of INR 1,441 Cr and a consolidated net profit of INR 59 crore, a stark turnaround from the loss reported in the same period last year. This financial health is a direct result of improved operational efficiency and a product mix increasingly skewed towards high-value solutions.

The most telling indicator of future success is the 110% year-over-year explosion in order intake. This is not just a number on a page; it represents deep partnerships with major global players. Key wins in FY26 include contracts with companies like Colt Technology Services, a global digital infrastructure firm expanding its network to handle AI and cloud traffic, and Netomnia, a rapidly growing UK fiber provider rolling out ultrafast broadband. These collaborations demonstrate that STL's advanced solutions are being integrated into some of the world's most ambitious digital infrastructure projects.

The 'Glass-to-Data Centre' Advantage

Underpinning STL's recent success is its unique 'Glass-to-Data Centre' vertical integration strategy. The company controls the entire value chain, from the complex chemistry of producing high-purity glass for optical fiber to designing and manufacturing sophisticated, pre-configured racks for AI data centres. This comprehensive ownership provides significant advantages, including stringent quality control, supply chain resilience, and the agility to co-create custom solutions with customers.

This vertical integration is the engine of STL's innovation, allowing its material scientists and network engineers to work in tandem to solve the industry's toughest challenges. It is this capability that enables the rapid development of products like Neuralis and Hollow Core Fibre.

"FY26 was a transformative year for us," said Ankit Agarwal, MD, STL, in the company's official announcement. "Our record order intake reflects our ability to co-create with customers and deliver advanced, high-capacity optical connectivity solutions for global hyperscalers and telecom providers. By owning the entire value chain—from glass chemistry to complex AI-DC racks—we are providing the physical foundation for the future of intelligence."

As STL enters FY27, it does so with powerful momentum. With a record order book providing strong revenue visibility and a portfolio of innovative technologies aligned perfectly with the demands of the AI era, the company has solidified its role as a critical architect of the world's digital future.
