    Managing Tariff Headwinds and Strategic Market Focus

    Q3 FY26 EBITDA margins were impacted by tariff-related headwinds, reducing reported margins by approximately 760 bps. Management is actively mitigating this through negotiations with customers to pass on costs, ramping up US production, and hoping for a resolution of the India-U.S. bilateral trade agreement. The company's strategic focus on FTTx, data centers, and 5G is creating a strong multiyear demand tailwind, with North America and APAC (ex-China) being key growth markets.
