📰 What's Happening

In Q1 FY27 (August 2026 filing), revenue surged 129% YoY to ₹690 crores and PAT grew 191% YoY to ₹58.5 crores, driven by strong order execution and new capacity ramp-up. The order book reached INR3,688 crores as of August 11, 2026, with ₹435 crores from data centre orders. Management targets INR4,500 crores revenue for FY27 and INR7,500 crores for FY28, supported by new CCV lines, LV cable expansion, and a 6th CCV line approval targeted for August 2026. EBITDA margin improved to 12.3% in Q1 FY27 from prior quarters, reflecting operating leverage. Board appointed Umeshkumar Chhaya as Whole-time Director effective August 13, 2026, pending shareholder approval at the upcoming AGM, enhancing leadership continuity.

EPS₹0.38₹0.53₹0.94₹1.15₹1.11

Revenue growth has accelerated sharply from ₹302 crores (Jun 2025) to ₹690 crores (Jun 2026), with OPM expanding from 7.8% to 9.5% and PAT growing at a faster pace than revenue, indicating improving operating leverage. Despite volatile historical margins, the current trajectory reflects management’s focus on margin expansion through scale and mix, supported by a backlog of high-margin orders. The shift from negative ROE and ROCE to positive operational momentum is now visible in execution, though sustainability depends on margin discipline amid rising capacity.

🔮 Management Outlook & What's Next

Management has provided forward guidance of INR4,500 crores revenue for FY27 and INR7,500 crores for FY28, targeting 11%-13% EBITDA margins. These targets are underpinned by new capacity additions, including commissioning of a new CCV line by December 2027 and expansion into LV cables in FY27-28. The 6th CCV line is expected to be approved by August 2026, signaling a structured capex cycle. Management emphasizes export growth, customer concentration reduction to 20%, and AI-driven efficiency gains as key levers to sustain momentum amid macro uncertainties.

The balance sheet shows a significant reduction in net borrowings from ₹610 crores (Mar 2026) to ₹2,537 crores in total assets with equity at ₹53 crores and reserves negative at ₹-657 crores, indicating high leverage and capital intensity. However, the company is not deleveraging aggressively — instead, it is financing growth through debt, likely tied to order book execution. The shift in depreciation reclassification from PPE reconciliation suggests improved accounting clarity post-restructuring, but the capital base remains thin relative to asset growth, warranting close monitoring of debt servicing capacity.

⚠️ Risk Factors

1. Execution risk in scaling new capacity (CCV lines, LV cables) without margin erosion or delays. 2. Customer concentration risk persists despite reduction efforts, with top customers still representing 20% of revenue. 3. High leverage and negative reserves raise concerns about financial resilience if order book growth stalls. 4. Dependence on government and infrastructure spending exposes the company to policy and execution delays in public projects.
