Hindustan Zinc Limited reported its highest-ever quarterly performance for Q4 FY26, with a 68% increase in net profit to ₹5,033 crore, driven by robust zinc and silver prices, record production, and lower operational costs. Revenue surged 49% to a record ₹13,544 crore, with earnings before interest, tax, depreciation, and amortisation (Ebitda) rising 61% to ₹7,747 crore. The Ebitda margin improved to 57% from 53% a year earlier. The company achieved record mined metal production of 315 kilotonnes and refined metal output of 282 kilotonnes. Hindustan Zinc's zinc production costs fell to ₹903 per tonne, solidifying its status as one of the lowest-cost producers globally. Silver production also rose 11% sequentially, contributing significantly to overall profitability. For the full fiscal year, Hindustan Zinc reported a 20% increase in revenue to ₹40,844 crore and a 34% rise in net profit to ₹13,832 crore. The company is focused on future growth, with plans for several projects, including a 510 kilotonnes per annum fertiliser plant and a 250 ktpa integrated refined zinc expansion, both expected to be completed by FY29.
