Sterlite Technologies delivered its strongest Q1 FY27, with revenue up 87% YoY to 1,910 crore and EBITDA of 397 crore (20.8% margin), driving net profit to 197 crore. The company also reported an all-time high open order book of 18,618 crore and completed a 1,500 crore QIP that enabled full net-debt elimination, underpinning a stronger balance sheet for AI-driven infrastructure growth. Management attributed the turnaround to higher-margin data center solutions, product mix improvement, and demand from hyperscalers and telecom operators, while highlighting progress in data center connectivity and AI data-center contracts. Operating efficiency and leverage supported margin expansion, and debt deleveraging alongside order book strength suggest robust visibility for future revenue. The results align with STL's strategic push into optical networking, enterprise data center connectivity, and global telecom deployments as AI builds out infrastructure. Overall, STL posted a landmark quarter, signaling a sustained upcycle in its core segments and underlining the impact of strategic financing on its balance sheet.
