Hindustan Zinc, a subsidiary of Vedanta Limited, on Friday released its fiscal first quarter earnings report with profit at Rs 2,234 crore, surpassing estimates. This was 4.73 per cent lower than Rs 2,345 crore recorded during the first quarter of FY25. It posted revenue from operations at Rs 7,771 crore, posting a decline of 4.42 per cent as against Rs 8,130 crore reported during the corresponding quarter of previous financial year. The drop in revenue was attributed to lower volumes and lower zinc and lead commodity prices partly offset by higher silver prices, stronger dollar, and higher by-product realisations.
