Hindustan Zinc’s $903/ton Zinc COP and FY27 Silver Plan

Hindustan Zinc Limited — Q4 & Full Year FY26 Earnings Call (held Apr 24, 2026)

1. Overall Tone of Management: Optimistic

• Management repeatedly emphasizes record performance and structural strength, e.g., “record-breaking fourth quarter,” “lowest quarterly zinc cost… since underground transition,” “all-time high financial performance.”
• Forward-looking language is confident: “we are confident in sustaining this strong performance” and “poised to invest decisively.”
• Even when discussing uncertainty, they frame it as manageable via cost leadership and hedging discipline.

2. Key Themes from Management Commentary

• Operational excellence & scale-up
• Crossed 1.1 million tons mined metal and sustained 1+ million refined metal for the 4th consecutive year.
• Q4: 315 KT mined and 282 KT refined; “highest ever mined and refined metal production.”
• Cost leadership (structural, not cyclical)
• Q4 zinc COP (ex-royalty): $903/ton, “lowest… since underground transition.”
• Full year COP: $959/ton, “five-year low” and below guidance of $1,000.
• Silver as the profitability engine
• Silver production: 176 tons in Q4; full year 627 tons (noted as impacted by mining sequence).
• Precious metals contributed 45% to overall profitability.
• Active inventory/price optimization: sold 12,000 tons lead concentrate; MIC/silver-equivalent sales used to enhance contribution.
• Growth projects progressing (2x expansion + fertilizer + technology)
• Debari integrated zinc smelter: 250 KTPA—site mobilization complete; engineering largely finalized.
• Rampura Agucha tailings reprocessing: groundwork commenced.
• Hot Acid Leaching: commissioning expected 2Q FY27 (first-of-its-kind).
• Fertilizer project: commissioning expected early 2Q FY27.
• Market & macro framing
• India remains resilient (GDP FY27 ~6.4%–6.9%).
• Base metals “relatively resilient”; medium-term outlook “constructive” due to structural demand and limited supply growth.
• ESG/sustainability & multi-metal narrative
• S&P Global Sustainability Yearbook: top 1% for 9th consecutive year.
• Chanderiya smelter: Zinc Mark and Copper Mark certification.
• Secured mineral blocks: potash, tungsten, rare earths with “clear timelines.”

3. Q&A Analysis

Theme A: Hedging strategy (zinc & silver)

• Core questions
• Hedge quantities for Q1 FY27 and FY27 full year.
• Whether hedging levels are sufficient given silver volatility.
• Hedging “loss/delta” and policy boundaries (10%–20%, max 12 months).
• Management response
• Q1 FY27 hedges: Zinc 20 KT (Apr–Jun avg $3,100); Silver 25 tons (avg $57).
• FY27 hedges: Zinc 71 KT (avg $3,225); Silver 59 tons (avg $60).
• Policy reiterated: hedge 10%–20%, “comfortable with 10%,” and not beyond 12 months.
• Hedging delta disclosed: Q4 delta ~INR1,100 cr; full year delta ~INR1,500 cr (framed as “delta,” not “loss”).
• Notable / evasive / strong points
• Strong clarification that hedging is not a mistake and is strategy-driven (“not worthwhile to experiment and do the hedging beyond 10%”).
• Some pushback on silver hedging timing: management admits after Q3 they did not hedge anything, but attributes it to policy rather than error.

Theme B: Silver production guidance & run-rate

• Core questions
• How to think about silver run-rate after Q4 (176 tons) vs FY27 guidance (680 ±10 tons).
• Whether silver can “spike” to 700–725 tons and what conditions drive it.
• Management response
• They will follow guidance: 680 tons for FY27.
• Explanation: silver output is constrained by zinc-rich ore economics and production mode; if zinc prices fall, they can tilt toward more lead/silver.
• Explicit condition: silver production spike to 700+ if zinc falls to ~$2,800–$3,000/ton (with silver ~$60/oz).
• They also cite that they already have MIC/silver-equivalent inventory: “we have got MIC in our hand… guidance of 680… already at 664 level”.
• Notable / evasive / strong points
• The “mutual exclusivity” logic is unusually direct: higher silver production is linked to zinc price weakness and zinc/lead mode decisions.
• Guidance appears conservative vs Q4 run-rate, but management provides a clear economic rationale.

Theme C: Cost of production (COP) trajectory & drivers

• Core questions
• Why Q4 COP was low vs full-year guidance; whether COP will rise in Q1 or later.
• Impact of natural gas shortage; RE proportion impact on COP.
• Management response
• Q4 benefit attributed to higher mining grade (7.9% vs full-year ~7.5%); grade sensitivity: 10 bps impacts $7.
• Geopolitical input-cost uncertainty acknowledged; they’ve “factored certain portion.”
• Gas shortage: only marginally higher cost (~$11/ton); no production impact.
• RE ramp: FY26 ~18%; FY27 expected 30%–35%.
• Notable / evasive / strong points
• They avoid quarter-wise COP guidance (“we don’t give guidance quarter-wise”), but still provide directional expectations.

Theme D: Other operating income/expenses jump (accounting & sustainability)

• Core questions
• Why “other expenses” jumped sequentially; what drives the ~INR600 cr both sides and whether it will continue/increase.
• Management response
• Accounting mechanics: ancillary “waste-to-wealth” agreements where residue sales hit other operating income, while purchases/WIP hit other expenditure.
• Amount: ~INR600 cr both sides (full-year basis).
• Forward: expected to increase to INR1,200–1,500 cr annually (both sides).
• Notable / evasive / strong points
• Clear accounting explanation; however, the “increase” forecast is qualitative and could materially affect reported expense/income optics.

Theme E: Capex execution & expansion phasing

• Core questions
• Status of phase 2 expansion plan; ordering timelines; whether delays exist.
• Smelter location (Rajasthan only) and mine renewal comfort (2030).
• Management response
• Phase plan changed: instead of multiple smelters, they consolidated into one location where ~600–700 KTPA smelter can be put; with the 250 KTPA, total becomes ~1.0 million ton smelter (and ~1.35–1.4 million ton metal).
• Ordering timeline: conceptual plan/layout and engineering; orders expected around June for mills; board announcement after feasibility in July timeframe.
• Mine renewal comfort: “first right of refusal” (premium may change, but “just by bidding people cannot take it away”).
• Notable / evasive / strong points
• They admit the earlier target to clear orders by January was missed (“slightly late”), but justify consolidation as cost-reducing.

Theme F: Dividend, brand fee/strategic services fee

• Core questions
• Why FY27 dividend declared early; dividend policy vs capex.
• Brand fee/strategic services fee amounts and contract validity.
• Management response
• Dividend: board declared first interim dividend similar to last year; dividend not dependent on current quarter profit; based on retained earnings.
• Brand fee/strategic services fee: contract valid till 2030; FY27 amount ~INR1,300 cr vs FY26 ~INR1,100 cr; settled end-of-year.
• Dividend policy: “minimum 30% of PAT… stays as of now regardless of capex.”
• Notable / evasive / strong points
• Strong correction: “we don’t have anything called royalty fee” (brand & strategic services fee only).

4. Guidance / Outlook

Explicit guidance (quantitative)

• FY27 production guidance
• Mined metal: 1,150 KTPA ± 10 KT
• Refined metal: 1,100 KTPA ± 10 KT
• Refined silver: 680 tons ± 10 tons
• FY27 zinc COP (ex-royalty)
• $975 to $1,000 per ton
• FY27 capex
• $500m to $600m (towards announced growth projects)
• FY27 renewable energy share
• 30% to 35%
• Hedging
• Q1 FY27: Zinc 20 KT, Silver 25 tons
• FY27: Zinc 71 KT, Silver 59 tons
• Fertilizer project commissioning
• Hot Acid Leaching commissioning: 2Q FY27
• Fertilizer commissioning: early 2Q FY27
• Ancillary business accounting
• Other operating income/expense: expected to rise from ~INR600 cr to ~INR1,200–1,500 cr annually (qualitative but with numbers)

Implicit signals (qualitative)

• Management expects resilient demand and “constructive medium-term outlook” for zinc/silver.
• They imply cost improvement potential if RE share rises further (they previously stated incremental RE reduces cost; reiterated in Q&A).
• Silver guidance is framed as economics-driven (zinc-rich ore + zinc price levels), not purely operational constraint.

5. Standout Statements (direct / revealing)

• Cost leadership claim
• “lowest quarterly zinc cost of production excluding royalty since underground transition at $903 per ton.”
• Silver profitability importance
• “precious metal portfolio… contributing 45.0% to the overall profitability.”
• Silver guidance economics
• “That can happen when the zinc prices fall to say $2,800 to $3,000 per ton… then… 700 tons plus.”
• Hedging policy boundary
• “we will not be going beyond 12 months… hedge between 10% to 20%.”
• “we stopped hedged after the 10% hedging.”
• Expansion consolidation
• “instead of doing that, why not bring everything together in one place? … design has been finalized.”
• Mine renewal comfort
• “we are comfortable because we have the first right of refusal.”
• Dividend policy
• “minimum 30% is the policy that stays as of now regardless of capex.”

6. Red Flags / Positive Signals

Positive signals
– Multiple record metrics in the same quarter/year: production, EBITDA, net profit, and lowest COP.
– Clear operational explanations for cost and accounting line items (ancillary agreements).
– Concrete FY27 production and COP guidance with tolerances.
– RE ramp plan quantified (30%–35% FY27) and linked to cost reduction logic.

Red flags
– Silver guidance appears conservative relative to Q4 run-rate; management ties it to zinc price scenarios, which introduces commodity-dependent variability.
– Hedging delta disclosed as large (INR1,100 cr Q4; INR1,500 cr FY), though framed as “delta,” still signals mark-to-market/price movement risk.
– Expansion phasing: admission of being “slightly late” on clearing orders by January; reliance on future ordering windows (June/July) increases execution risk.
– Ancillary business growth forecast (INR1,200–1,500 cr annually) could increase volatility in reported “other” lines.

7. Historical Comparison & Consistency Analysis (vs prior calls)

a. Change in Tone Over Time

• Current (Apr 2026): More Optimistic
• Stronger emphasis on “all-time high” financials and confidence in sustaining performance.
• Prior calls
• Q3 FY26 (Jan 2026): also optimistic, but more focused on “strong quarter” and silver wave; less explicit FY27 cost/volume confidence.
• Q2 FY26 (Oct 2025): optimistic but included revised FY26 refined metal guidance and emphasized “tepid global growth.”
• Q1 FY26 (Jul 2025): optimistic but acknowledged silver volume shortfall drivers (grade/availability) and expected improvement via commissioning.

Shift drivers
– Management now provides full FY27 quantitative guidance (volumes, COP, silver) and shows actual FY26 execution at record levels—reducing uncertainty in narrative.

b. Tracking Past Commitments vs Outcomes

• Silver guidance confidence (Q1 FY26 call, Jul 2025)
• Past statement: expected commissioning/debottlenecking to drive “Q3, Q4 will see much better numbers… help us reach guidance.”
• Outcome by Q4 FY26: silver Q4 176 tons and FY26 silver 627 tons (guidance not explicitly restated here, but management frames FY26 as record profitability with silver contribution).
• Assessment: ✅ Directionally delivered (silver cycle monetized; however FY26 silver was “impacted by change in mining sequence,” suggesting not perfectly smooth).
• Roaster/availability-driven volume recovery (Q2 FY26 call, Oct 2025)
• Past statement: revised FY26 refined metal guidance due to lower availability in H1; expected H2 improvement.
• Outcome by FY26: refined metal 1,048 KT (second highest) and Q4 record refined output.
• Assessment: ✅ Delivered (H2 strength consistent with prior expectations).
• Cost sustainability (Q2 FY26 call, Oct 2025)
• Past statement: COP guidance revised down to around $1,000; sustained COP expected $950–$1,000.
• Outcome by FY26: COP $959 (five-year low) and Q4 $903.
• Assessment: ✅ Delivered.

c. Narrative Shifts

• From “silver rally/visibility” → “silver economics constrained by zinc price”
• Earlier calls leaned into silver upside potential; now management explicitly states silver spikes depend on zinc price falling and production mode economics.
• From “growth projects progressing” → “growth projects with tighter execution milestones”
• Current call provides more specific commissioning windows (Hot Acid Leaching 2Q FY27, fertilizer early 2Q FY27) and FY27 production/cost guidance.
• Ancillary business accounting becomes a bigger narrative
• The “other operating income/expense” mechanism and expected scaling to INR1,200–1,500 cr annually is new emphasis.

d. Consistency & Credibility Signals

• Medium-to-High credibility
• Cost and production execution appears consistent with prior guidance ranges (COP and volumes).
• Hedging policy is consistent across calls: 10%–20%, not beyond 12 months.
• Credibility caveat
• Silver guidance is increasingly framed as commodity-dependent and mode-dependent, which can reduce confidence in “steady run-rate” expectations.

e. Evolution of Key Themes

• Demand/market: stable-to-constructive (India resilient; structural silver deficit narrative strengthened).
• Margins/costs: improving/stable—COP repeatedly framed as structurally low and now anchored by FY26 outcomes.
• Expansion: execution confidence increased, but with some schedule slippage acknowledged (orders late vs January target).
• ESG: consistently highlighted; now includes more certifications and index inclusions.

f. Additional Insights (cross-period intelligence)

• Management’s silver narrative has shifted from “capacity/technology will unlock silver” (earlier) to “silver is constrained by zinc-rich ore economics and production mode,” implying that even with operational capability, economic dispatch may limit silver output in strong zinc price environments.
• The ancillary “waste-to-wealth” agreements appear to be a growing lever for reported income/expense optics—management is proactively explaining accounting to pre-empt analyst confusion.
