Sterlite Tech. (532374) Jul 2026 Filing Analysis

North America increased from 25% of revenue in H1 FY25 to 33% in H1 FY26, an 8 percentage-point expansion. In the later baseline, the Americas represented 53.5% of revenue, confirming that this became the company's largest and fastest-growing geographic market. This is a major positive geographic shift, driven by telecom, broadband and data-centre demand. (5 expanding)

Order visibility was strong in Q2 FY26, with the open order book rising from Rs. 4,888 Cr in Q1 FY26 to Rs. 5,188 Cr in Q2 FY26, a 6.1% quarterly increase. Rs. 820 Cr was scheduled for execution in Q3 FY26 and Rs. 4,368 Cr thereafter. The later baseline shows a much larger Rs. 18,618 Cr order book, indicating substantial expansion in visibility over time. (5 expanding)

The digital business generated Rs. 65 Cr in Q2 FY26 revenue and Rs. 1 Cr EBITDA, implying roughly 3.8% of total Q2 revenue. In the later baseline, revenue was Rs. 72 Cr in Q1 FY27, still about 3.8% of consolidated revenue, with Rs. 2 Cr EBITDA. Therefore, the segment expanded in absolute revenue and EBITDA while retaining a small, stable share of the company. (5 expanding across 2 engines)

Order intake more than doubled year-on-year to Rs. 1,340 crore in Q2 FY26. The company also reported multi-year European supply agreements, renewed US Tier-1 telecom inflows, and several data-centre opportunities in the pipeline. The latest quarter therefore shows a clear acceleration in demand signals. (4 accelerating, 1 new trend across 5 signals, 1 leading indicator)

The total order book increased by Rs. 300 crore quarter-on-quarter, from Rs. 4,888 crore in Q1 FY26 to Rs. 5,188 crore in Q2 FY26. This indicates positive and improving near-term revenue visibility, although the available history is too short to establish a longer acceleration pattern. (5 accelerating across 5 signals)

Tariff pressure intensified in the latest reported quarter. Management said the US tariff reset reduced reported EBITDA margin by around 300 basis points, or 3.1% of EBITDA, and that STL bore most of the cost on fixed-price contracts. At the same time, underlying operational EBITDA improved from 11.2% in Q2 FY25 to 14.4% in Q1 FY26 and 16.7% in Q2 FY26. Therefore, the structural margin trend improved, but the immediate external cost shock remained material. Compared with the later Sep 2026 baseline, the risk remains high because the baseline still requires a large expansion from 13.2% FY26 EBITDA margin to at least 27% by FY29.

The older January 2026 evidence showed recovery rather than deterioration: Q3 revenue was INR 1,257 crore and 9M revenue increased 12% year on year to INR 3,311 crore. Optical Networking revenue also grew to INR 3,115 crore for 9M, supported by orders and data-centre demand. However, the business remained cycle-dependent, with optical networking contributing roughly 94% of 9M revenue. Compared with the later baseline, where optical networking was still about 96% of quarterly revenue, the concentration remained high. The risk is therefore stable, not resolved. (2 stable, 2 high-severity)

The order book increased from INR 4,888 crore in Q1 FY26 to INR 5,188 crore in Q2 FY26, but only INR 820 crore was scheduled for Q3 FY26 while INR 4,368 crore was scheduled for FY26 and beyond. This creates execution and timing risk: a substantial majority of the backlog was not due for immediate delivery. Management also acknowledged supply-timing challenges to the US during the quarter. Compared with the later baseline, where about 88% of the much larger order book was scheduled for Q3 FY27 and beyond, the risk remains material and appears more pronounced in the later period.
