MUMBAI, India, July 24, 2026 /PRNewswire/ -- 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. For Q1 FY'27, the Company reported the highest-ever revenues of INR 1,910 Cr and EBITDA of INR 397 Cr, a YoY growth of ~87% and ~184%, respectively. The open order book stands 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.

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)'.
