The Silver production and refining segment exhibits high growth potential and dominant market positioning. As of December 2025, Hindustan Zinc has solidified its status as the world's third-largest silver producer with an annual production capacity reaching 800 metric tonnes. The segment's profitability is exceptional, contributing approximately 38%-40% to the company's total earnings before interest and tax (EBIT) following a 178% surge in silver prices year-over-year. Market demand remains robust, driven by the clean energy transition where silver is a critical component for photovoltaic cells in solar panels. To capitalize on this momentum the company is executing a demerger strategy to unlock value and has prioritized high-grade silver mining areas to increase second-half FY2026 output to over 380 tonnes.

Value-added zinc alloys represent a high-growth vertical within the core metals portfolio. This segment now contributes approximately 22% to total business revenue, reflecting a strategic shift toward specialized products such as Continuous Galvanizing Grade (CGG) and Die Casting Alloys. The market for these alloys is expanding in line with India's domestic steel production trajectory toward an estimated 300 million tonnes by 2030, increasing demand for high-quality galvanizing materials. Hindustan Zinc recently commissioned a 30 KTPA zinc alloy plant, secured new BIS certifications, and is seeing EBITDA margins for these specialized products exceed the company's standard 51% average. Significant CAPEX is being allocated to expand roaster capacity to 160 KTPA to support scalable alloy output.

EcoZen, the Green Zinc brand, is a pioneer in the low-carbon metals market and qualifies as a Star due to high growth prospects and premium positioning. Launched as Asia's first low-carbon zinc product, EcoZen reports a carbon footprint of less than 1 tCO2/t of metal - roughly 75% lower than the global industry average. This product targets environmentally conscious global supply chains, notably in electronics and electric vehicle components where Scope 3 emission reductions are increasingly mandatory. The company has secured a 530 MW Renewable Energy Round-the-Clock (RE-RTC) power delivery agreement to scale production of these green minerals. Renewable energy usage has increased to 19% of the power mix as of late 2025, supporting double-digit annual demand growth for low-carbon metals.

Critical minerals and rare earth exploration is an emerging Star segment aligned with national strategic priorities. Hindustan Zinc has secured one of India's first potash concessions and is actively advancing exploration in lithium and other battery-critical minerals. The market for these commodities is expected to grow at a CAGR exceeding 20% as India scales semiconductor and EV battery manufacturing. The board-approved Rs 12,000 crore expansion plan aims to double integrated production capacity and includes facilities dedicated to minor metal recovery. By leveraging existing mining and processing infrastructure, the company aims to capture significant share of the nascent critical minerals market in South Asia.

Strategic actions and enablers for Star segments:

• Operational: Prioritize high‑grade zones and ramp-up mining tonnage for silver; optimize smelter throughput to support 800 tpa capacity.
• Investment: Allocate targeted CAPEX (Rs 12,000 crore program) to expand roaster and downstream alloy capacity, and to build minor metal recovery lines.
• Commercial: Execute demerger and branding strategies (EcoZen differentiation) to capture premium pricing and attract ESG‑sensitive contracts.
• Energy & sustainability: Scale RE-RTC power delivery to increase renewables share well beyond 19% and certify low-carbon footprints for export markets.

Risk-management metrics and KPIs to monitor:

• Production KPIs: tpa achieved vs. capacity (silver 800 tpa; alloys 30 KTPA baseline; roaster target 160 KTPA).
• Financial KPIs: EBIT % contribution by segment (silver 38%-40%; alloys ~22% revenue share), segmental EBITDA margins (specialty alloys >51%).
• Price exposure: Sensitivity of segment EBIT to metal price moves (silver price volatility impact after +178% YoY).
• Sustainability KPIs: CO2e/t for EcoZen (<1 tCO2/t target); % renewable energy in power mix (target >19%).
• Project delivery: Adherence to Rs 12,000 crore capex timetable and demerger milestones.

Hindustan Zinc Limited (HINDZINC.NS) - BCG Matrix Analysis: Cash Cows

Cash Cows

Primary zinc mining and smelting remains the company's most dominant and stable revenue generator. As of December 2025, Hindustan Zinc maintains a commanding 77% market share in India's primary zinc market, effectively operating as a near-monopoly. The segment reported a record-breaking FY2025 revenue of Rs 34,083 crore, supported by a 4-year low cost of production at approximately $1,052 per tonne. With an industry-leading EBITDA margin of 51% and a Return on Capital Employed (ROCE) of 58%, this business unit generates massive free cash flow of over $1.6 billion annually. The company's vast reserves of 453.2 million tonnes ensure a mine life of over 25 years, providing long-term stability for dividend payouts.

Lead production and refining provides consistent cash flows with high market maturity. Hindustan Zinc is the largest integrated lead producer in India, benefiting from steady demand in the automotive and industrial battery sectors. Global lead market growth is modest at a 1.7% CAGR, yet the company's integrated model allows it to maintain high profitability through vertical integration, low unit costs and product mix optimization. The segment contributes materially to overall refined metal output - consolidated refined metal production reached a historic high of 1,052 KT in the latest fiscal year. Cash generated from lead operations is frequently reinvested into higher-growth segments like silver and fertilizers.

• Refined metal production (FY2025): 1,052 KT (all metals combined)
• Global lead market CAGR: 1.7%
• Role: Stable, low-growth revenue contributor; source of internal funding for growth initiatives

Captive power generation and waste heat recovery units serve as internal cost-saving engines. The company operates a robust portfolio of captive thermal and solar power plants, including 40.70 MW of solar and 48.46 MW of waste heat recovery capacity. These units ensure a reliable energy supply for smelting operations, shielding the company from volatile grid electricity prices and reducing operational energy consumption by over 100,000 GJ in FY2025. By achieving 100% renewable power at the Pantnagar Metal Plant, Hindustan Zinc has optimized its cost structure to remain in the lowest quartile of the global cost curve. This internal infrastructure materially supports the high margins seen in the core metals business.

Sulphuric acid and other smelting by-products generate steady ancillary income with minimal additional investment. As a by-product of the zinc and lead smelting process, sulphuric acid is sold to domestic chemical and fertilizer industries, contributing to the 'other' revenue segment. The company has optimized its fumer plants to reduce waste and increase recovery of these by-products, saving nearly 40,000 tonnes of jarosite waste annually. This segment benefits from the high utilization rates of the core smelters and provides a consistent stream of high-margin revenue. Integration of these by-products into the upcoming fertilizer project will further enhance value extraction from this cash-generating unit.

• Sulphuric acid: Regular off-take to chemical & fertilizer sectors
• Jarosite waste reduction: ~40,000 tonnes saved annually
• Integration: By-products to feed planned fertilizer project, increasing margin capture

Hindustan Zinc Limited (HINDZINC.NS) - BCG Matrix Analysis: Question Marks

Question Marks - New fertilizer manufacturing project: Hindustan Zinc is investing Rs 1,700-1,800 crore to construct a 0.5 million tonne per annum DAP/NPK plant in Rajasthan, targeted for commissioning by December 2026. India imports roughly 60% of DAP demand (est. ~3.0-3.5 million tonnes p.a.), presenting a potential addressable market of ~Rs 15,000-20,000 crore annually for DAP/NPK combined; Hindustan Zinc projects segment revenues of Rs 2,000-2,500 crore p.a. on full ramp-up. Key value drivers include integration of sulphuric acid by‑product streams for low-cost sulphur supply and captive sulphuric acid production to reduce feedstock costs. Primary risks: volatile elemental sulphur and phosphoric acid feedstock prices, time-to-commission execution risk (Dec 2026 target), and incumbent domestic players with established offtake and distribution networks.

Question Marks - Zinc‑based battery R&D: Hindustan Zinc is allocating R&D and pilot CAPEX into zinc‑air and zinc‑nickel battery chemistries to target stationary and niche mobility energy storage markets. Global energy storage market CAGR projections vary by segment (utility-scale storage CAGR ~20-25% to 2030; distributed storage higher in emerging markets). Zinc battery commercialization remains at pilot to early demonstration phase with negligible market share as of late 2025. Estimated near‑term R&D and pilot investment: Rs 100-300 crore over 3-5 years (company disclosures and comparable metal‑to‑battery initiatives). ROI uncertainty is high due to technology scale-up risk, cycle life and energy density gaps versus Li‑ion, and need for cell manufacturing partnerships. Strategic rationale: leverage zinc supply chain and mining-to-metal integration to provide low‑cost cells if technical hurdles (cycle stability, power density, manufacturing yields) are resolved.

• Estimated R&D & pilot CapEx: Rs 100-300 crore (3-5 years)
• Commercialization status (Dec 2025): pilot / early demo; market share: <1%
• Market growth (relevant): utility & distributed energy storage CAGR ~20-25% to 2030
• Main technical risks: cycle life, energy density, scale-up costs

Question Marks - International mining asset acquisitions: Hindustan Zinc has signalled interest in acquiring critical mineral assets in Southeast Asia and neighboring regions to diversify resource base beyond Rajasthan. These exploratory acquisition plans as of December 2025 lack finalized targets; potential targets include polymetallic and critical minerals (e.g., nickel, cobalt, manganese, battery‑grade zinc concentrates). Potential transaction sizes under consideration range from small bolt‑on assets (USD 50-200 million) to transformational buys (>USD 500 million). Expected benefits: resource diversification, access to new commodity streams, vertical integration for battery raw materials. Key downsides: elevated regulatory, permitting and geopolitical risk; integration complexity; FX exposure; and capital allocation trade‑offs versus high‑return domestic projects.

• Cross‑cutting financial impacts: aggregate incremental CapEx (fertilizer + batteries + potential acquisitions) could exceed Rs 2,000-3,000 crore over 2024-2027 depending on deal activity and R&D scaling.
• Decision levers: successful fertilizer commissioning with sulphuric acid integration would materially de‑risk and free cash flow to fund other Question Mark initiatives; failure or delays would intensify capital allocation pressure.

Hindustan Zinc Limited (HINDZINC.NS) - BCG Matrix Analysis: Dogs

Question Marks - Dogs: Traditional jarosite waste disposal is a declining and high-cost operational burden. Historically, Hindustan Zinc generated large volumes of jarosite smelting waste (estimated legacy inventory >2.5 million tonnes across multiple legacy sites as of FY2023) that required expensive land-filling, long-term environmental monitoring and remediation. Annual maintenance, monitoring and compliance for legacy jarosite sites is estimated at INR 120-180 crore per annum, producing zero revenue while consuming capex and working capital. The company's transition to fumer (fuming) technology and circular economy initiatives (metal recovery pilots yielding up to 60-75% incremental zinc/iron recovery from treated residues) is actively phasing out the "business of waste" in favor of revenue-generating metal recovery.

As the company targets zero waste to landfill and a 5x water-positive status, traditional disposal methods are being replaced by more efficient processes, including residue beneficiation, solvent extraction-electrowinning (SX-EW) application to secondary streams, and partnerships for residue valorisation. Remaining legacy waste sites contribute negative EBITDA and are classified operationally as non-core liabilities with multi-year remediation schedules tied to statutory closure plans and ESG commitments.

High-cost legacy thermal power assets are being de-emphasized in favor of renewables. Captive thermal plants commissioned in the 1990s-2000s (aggregate installed thermal capacity ~200-300 MW across operations historically) relied on domestically/ imported coal and have increasingly become uneconomic versus renewable PPAs. Average variable costs for these thermal units have been reported in the range INR 5.5-7.5/kWh versus solar and wind PPA rates of INR 2.5-3.5/kWh secured in recent contracts, compressing thermal unit ROI and raising marginal cost of production for zinc and silver concentrate processing.

Regulatory carbon costs (current effective carbon pricing equivalent estimates and carbon tax exposures approximated at INR 25-40/tonne CO2e in sensitivity scenarios) plus internal shadow carbon pricing under Net Zero 2050 planning reduce the net present value of these assets. Hindustan Zinc aims to source ~70% of its electricity from renewable sources by FY2028 via on-site solar + wind and long-term renewable energy agreements - a shift that implies progressive retirement, retrofit (SCR, efficiency upgrades) or conversion of older thermal capacity.

Non-core minor metal residues with low recovery rates are being divested or outsourced. Certain smelting and hydrometallurgical residues contain trace precious and minor base metals (silver, indium, cadmium, lead traces) but at concentrations below in-house economic thresholds (typical contained value

Strategic partnerships (e.g., Runaya Green Tech and other specialized recyclers) and tolling agreements have been implemented to outsource processing of low-value residues, thus freeing capital and internal smelting capacity for high-purity silver and zinc production. Outsourcing improves capital efficiency (reduced incremental capex requirement estimated at INR 300-500 crore over a 3-5 year window) and reduces operational complexity while maintaining compliance with circular economy KPIs.

Key operational and financial risks related to these "dog" segments include:

• Residual remediation liabilities: projected cash outflows for closure and monitoring of legacy sites over 10-20 years.
• Stranded asset risk: declining ROI on thermal plants leading to potential write-downs and accelerated depreciation.
• Price and technology risk: falling renewable tariffs and improved residue recovery tech compress the economics of legacy disposal and small-scale in-house recovery.
• Regulatory and ESG compliance costs: higher capex and opex to meet evolving environmental norms and investor-driven ESG metrics.

Metrics to monitor for these Question Mark / Dog areas:

• Annual remediation and monitoring expenditure (INR crore).
• Volume of jarosite and legacy residues (tonnes) versus tonnes processed for recovery.
• Percentage of power from renewables (%) and PPA price (INR/kWh).
• Marginal cost of production (INR/kg Zn) attributable to legacy assets.
• Third-party recovery throughput (tonnes) and tolling revenue/costs (INR crore).
