Hindustan Zinc quarterly profit more than doubles, cuts FY2027 cost outlook

The significance here lies less in the earnings beat — higher metal prices flatter every producer — than in the cost guidance cut, which points to structural gains from rising output and by-product credits rather than a one-off price tailwind. That distinction matters for anyone tracking zinc supply economics, since lower unit costs can sustain margins even if prices cool. The open question is whether the by-product revenue strength and volume growth persist into FY2027, or whether the lowered forecast rests on assumptions that shift with prices.
