MUMBAI, India, July 24, 2026 — STL (NSE: STLTECH), a leading connectivity solutions provider for AI-ready digital infrastructure, today announced its financial results for the quarter ended 30 June 2026.

Key Highlights

• Record order book of INR 18,618 Cr
• EBITDA and PAT hit a record INR 397 Cr and INR 197 Cr, respectively
• Achieved 'net debt-free' balance sheet

Financial Performance

For Q1 FY'27, the Company reported the highest-ever revenues of INR 1,910 Cr and EBITDA of INR 397 Cr, representing year-on-year growth of approximately 87% and 184%, respectively. The order book stood at INR 18,618 Cr at the end of the quarter.

STL reported a robust EBITDA margin of 20.8% in Q1 FY27, the highest level achieved in nearly 20 quarters, driven by an improved product mix and operating leverage. Margin resilience was further supported by a higher contribution from the Data Center (DC) business, reflecting the Company's increasing alignment with the AI-led data center buildout.

Strengthened Balance Sheet

To further strengthen its position, the Company recently secured a Qualified Institutions Placement (QIP) of INR 1,500 Cr. The successful fund raise enabled the Company to become net debt free while providing the capital required to accelerate its next phase of growth. Reflecting this strengthened balance sheet and improved credit profile, CRISIL revised its rating outlook to 'Stable', while ICRA upgraded the Company's credit rating to 'AA (Stable)'.

Key Order Wins

• Secured multiple hyperscaler orders worth $100 Mn+ for the Neuralis portfolio — STL's integrated data center solutions
• Secured a strategic order to supply long-haul, dark-fibre High Density Micro-cables to a major connectivity infrastructure provider

Innovation, Research and Development

• AI-DC Portfolio: Neuralis, a purpose-built connectivity suite for AI-Data Centers, enabling ultra-high-density cabling for GPU-intensive workloads
• CONCAT: A pre-connectorized, plug-and-play solution that reduces onsite labour and installation costs
• US Conec-certified MMC Pre-Terminated solutions: Delivering a 3X increase in cabling density to power the 800G+ future of AI data centers

Decisive Win in Europe Patent Dispute

This win reinforces the strength of STL's IP portfolio, which now stands at 785+ patents, underscoring the Company's sustained investment in innovation and its ability to protect and monetize its technology as it scales globally. It also further strengthens STL's position in Optical Connectivity markets across the UK and Europe.

Management Commentary
