Executive summary

  • Achieved strong revenue growth in Q3 FY26, with consolidated revenue at INR 1,257 crore, up 26% year-over-year and 22% sequentially, driven by both volume and value-added product sales, especially in optical networking and digital segments.

  • Maintained global leadership in optical networking, with 8% market share outside China and significant innovation in next-gen fiber technologies and AI-ready data center solutions.

  • EBITDA margin moderated to 10.3% in Q3 FY26 due to US tariff headwinds, but operational EBITDA improved sequentially over the last five quarters.

  • Net loss after tax from continuing operations was INR 17 crore for the quarter, impacted by exceptional items and tariff resets.

  • Order intake rose 40.3% year-over-year to INR 4,263 crore for 9M FY26, with large-scale data center and Tier-1 North American telco wins.

  • Targeting 30% revenue contribution from enterprise and data center business within 12–18 months, up from current 20%.

  • Margin recovery anticipated as mitigation measures for tariffs take effect and new contracts reflect higher costs.

  • Focused on scaling AI-ready and high-value fiber solutions, with new product launches in G.654.E and hollow core fiber expected to drive future growth.

  • Management is actively appealing a significant US litigation verdict and the ultimate financial impact is currently indeterminable.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
