Hindustan Zinc Q2 FY27: Record Profits, Lower Costs and a Silver Surge

Hindustan Zinc reported its Q2 FY27 results recently, and the quarter turned out to be its strongest on record. Revenue grew 77% year on year, net profit more than doubled, and the cost of producing zinc fell to its lowest level in recent memory. 
 

At the current market price of ₹538, the company’s market capitalisation stands at: approximately ₹22,732 crore.
Here is a breakdown of the quarter, what the company is planning next, and what retail investors should keep an eye on.

Hindustan Zinc reported a strong set of numbers across the board in Q2 FY27 (July to September 2026). Here is a quick look at the key figures:
 

• Revenue growth: ₹15,093 crore, up 77% from the same quarter last year, driven by stronger metal prices and higher production volumes across zinc and silver.

• Operating profit: ₹9,285 crore, up 108% year on year, with an operating margin of 62%. In simple terms, the company kept ₹62 of every ₹100 it earned as operating profit, which is an extremely healthy number for any commodities business.

• Net profit: ₹6,412 crore, up 142% from Q2 last year, marking the highest quarterly profit the company has ever reported.

• Production cost: The cost of producing one tonne of zinc dropped 29% to $703, prompting management to revise the full year cost guidance down to $825 to 850 per tonne from the earlier estimate of $975 to 1,000.

• Silver output: 173 tonnes in Q2, up 20% from last year, with silver contributing roughly 45% of total profits in the first half of FY27, making it nearly as important to earnings as zinc itself.

• Cash generation: Free cash flow before growth capex stood at ₹6,389 crore, which gives the company enough internal funding to support its expansion projects without needing to stretch the balance sheet.

What stands out is that costs fell sharply at the same time as metal prices and production volumes went up, and that combination created a compounding effect on profits. This is why the bottom line grew far faster than the top line.

One important thing to note here is that part of this cost reduction came from strong realisations on sulphuric acid, which is a byproduct generated during zinc smelting that the company sells. If sulphuric acid prices soften in the coming quarters, the cost picture could look less favourable, so the $703 number, while impressive, is not entirely within the company's direct control.

Three things are shaping the company's direction from Q2FY27 management guidance:
 

• Zinc expansion: The company is building a project that would add 250,000 tonnes per year of integrated zinc capacity, with engineering and procurement nearly complete and mine development already underway. Full year capex for FY27 is guided at ₹5,000 crore, with most of the spending expected in the second half as construction ramps up, and this remains the primary medium term growth driver for the company.

  
   

• Silver growth: Management is targeting 680 tonnes of silver production for FY27, and with 320 tonnes already produced in the first half, the company is well on track. Silver’s global demand is being driven by solar panels, electronics and electric vehicles, and Hindustan Zinc gives investors indirect exposure to that structural shift.

• Supply dynamics: The broader commodity environment currently favours producers, with global refined zinc supply expected to fall short of demand by about 180,000 tonnes in 2026, which should keep prices firm. Silver is expected to remain in deficit for the sixth straight year, with a shortfall of roughly 1,440 tonnes, largely because demand from the solar energy buildout is outpacing new mine supply.

To manage price volatility, the company has hedged 40,000 tonnes of zinc in Q3 at $3,476 per tonne and 36,000 tonnes in Q4 at $3,698 per tonne, while silver is hedged only for Q3 at $68 per ounce. Beyond these positions, realisations are fully exposed to whatever the market does.

On the sustainability front, renewable energy accounted for 27% of power consumption in Q2 and management is targeting 35% by Q3 FY27, which should help reduce dependence on conventional energy and support operating costs over time.

• Cost sustainability: A meaningful portion of the cost improvement this quarter came from strong sulphuric acid realisations, and if those prices drop, the production cost will rise even if nothing else changes. Investors should look at the cost of production excluding sulphuric acid benefits to understand how sustainable the current margins really are.

• Silver volatility: Silver prices have historically been volatile and the company's hedging covers only Q3 at $68 per ounce, which means a sharp correction in silver would directly hit nearly half of the company's earnings given that silver now contributes roughly 45% of profits.

• Geopolitical pressures: Management has flagged that supply chain disruptions and input cost inflation from ongoing geopolitical tensions could add roughly $50 per tonne to production costs, partially offsetting the cost gains made this quarter.

• Expansion execution: The 250,000 tonne zinc expansion is still in progress, and mining projects of this scale are prone to delays and cost overruns. Until the project is commissioned and operating at scale, the growth it promises remains a possibility rather than a certainty.

Hindustan Zinc delivered a quarter that checked nearly every box: record profits, sharply lower production costs, a growing silver business and a supportive commodity environment. The company is investing in growth and generating enough cash internally to fund it.
 

Will this solid performance continue? That depends on commodity prices holding up, the zinc expansion being delivered on schedule, and cost discipline continuing even without the sulphuric acid tailwind. If those pieces come together, there is a genuine case for sustained earnings improvement, but if any of them change, the current margins may prove to be a one off event than baseline.
