1. Includes 2.6 kt, 3.7 kt, 3.5 kt, 13.7 kt and 10.1 kt from Hindustan Zinc Alloys (100% subsidiary of HZL) in 4QFY26, 4QFY25, 3QFY26, FY26 and FY25 respectively.

4QFY26:

• Best ever quarterly mined metal production at 315 kt driven by higher ore production & better grades.
• Record quarterly refined metal production at 282 kt driven by additional capacity unlocked by the debottlenecking projects at Chanderiya & Dariba, improved operational efficiency & higher plant availability.
• Silver production at 176 metric tonnes, up 11% QoQ in line with lead production.
• Wind power generation at 56 MU, in line with wind velocity.

FY26:

• Highest ever mined metal production at 1114 kt, in line with higher ore production and better grades.
• Best achieved refined zinc production at 851 kt, up 3% YoY driven by commissioning of debottlenecking projects & 160 ktpa roaster along with Pyro operations on zinc-lead mode for full year.
• Refined lead production at 197 kt, down 13% YoY, primarily on account of Pyro operations ran partially on lead mode in the previous period & lower plant availability.
• Silver production at 627 metric tonnes, in line with lead production and lower silver input from mines in accordance with the mining sequence.

• Wind power generation at 372 MU, up 7% YoY in line with wind velocity.
