Bear-case history
Risks carried through the record.
high
Zinc International acquisition uncertainty
Management provided no update on the Zinc International acquisition, indicating no progress; regulatory hurdles may persist.
Potential increase in brand fee or royalty rates
Analyst raised concern about brand fee (currently 2%) and possible royalty rate changes; management declined to comment on future changes.
Project execution delays
While management expressed confidence in project timelines, any delays in commissioning of alloy plant, roaster, or fertilizer plant could impact growth targets.
Supreme Court ruling on mining cess
The Supreme Court reserved judgment on whether states can levy additional surcharge/cess on mining. A retrospective application could increase costs, though management believes the impact is immaterial.
Global zinc price volatility
Zinc prices declined from Q1 highs due to lack of Chinese stimulus, European slowdown, and geopolitical uncertainties. Management expects prices to recover only by Q4 FY25.
Silver production dip due to WIP accumulation
Sellable silver production dropped 7% YoY in Q1 due to WIP accumulation from late mode of pyro operation. While management expects liquidation, any delay could impact silver volume guidance.
Lower silver grades impacting production
Silver grades at SK mine are 5-10 ppm lower YoY, leading to lower Q1 silver output; recovery depends on H2 debottlenecking.
Fumer capacity running below target
Fumer is operating at 20mt/month vs 33mt capacity due to Chinese visa issues and lower input; may delay silver ramp-up.
Potential royalty increase on mines
Analyst raised concern about royalty increases as mine leases expire around 2030; management acknowledged worst-case scenarios but did not quantify.
Brand fee increase and promoter stake sale
Brand fee rose from 2% to 3% of revenue, while Vedanta reduced stake; analyst questioned linkage, management declined to comment on ownership moves.
Global zinc demand weakness
Muted global demand due to sluggish economies in US, China, and Europe could pressure prices and volumes.
Coal price volatility
Thermal coal prices are fluctuating; any sustained increase could impact cost guidance.
NCLT approval for general reserve conversion pending
The conversion of general reserve to retained earnings is still awaiting NCLT order, with next hearing on Nov 8.
DAP project execution risk
Fertilizer project depends on rock phosphate availability from RSMM and imports; commissioning timeline is 18-24 months.
Fumer ramp-up delays
The fumer plant faced technical difficulties and visa issues for Chinese experts; a long shutdown is planned to rectify design inefficiencies.
Supreme Court mining royalty judgment
A retrospective liability of INR 83 crore was provided as an exceptional item; further clarity on quantification is awaited.
Mine lease expiries in 2030
Zawar and Rampura Agucha mine leases expire in 2030; management has not provided a clear cost escalation scenario for renewal auctions.
Geopolitical and macro uncertainty
US elections and geopolitical tensions could impact metal prices; management expects zinc to remain around $3,000/ton near-term.
Execution delays in growth projects
Roaster 6 commissioning delay impacted H1 production; similar delays in 250ktpa smelter or tailings plant could affect volume ramp-up.
Silver grade decline at SK Mine
Current silver grade is ~90 ppm, lower than historical levels, limiting silver production growth despite price tailwinds.
Hedging limits upside in a rising price environment
Management hedges 10-20% of production; current hedges at $2,872/ton for zinc and $37/oz for silver cap gains if prices rise further.
Demerger uncertainty
Management believes demerger would unlock value but no timeline provided; regulatory or shareholder hurdles could delay.
Global zinc demand weakness
Zinc demand remains subdued in Europe and the US, with Chinese stimulus not yet boosting prices as expected.
Business restructuring plan delayed
The board-approved restructuring plan is pending agreement from government nominee directors; management expects closure by March/April 2024.
Domestic coal availability volatility
Domestic coal availability declined from 45% in Q2 to 30-31% in Q3, though power plant modifications allow higher ash coal usage.
Silver production guidance miss
Silver production guidance revised down to 700-710 tons from 750-775 tons due to Fumer shutdown and geotechnical issues at SK mine.
Chinese visa issues impacting Fumer operations
Visa challenges for Chinese partners have hindered Fumer operations; management is hopeful but uncertain about resolution.
Geotechnical issues at SK mine
Geotechnical challenges at SK mine affected mine sequencing and silver output; management says they have mechanisms to address but risks remain.
Execution risk in expansion projects
Large capex plans ($2-2.5 billion) for expansion to 2 million tons carry execution and funding risks, though management has a phased approach.
Commodity price volatility
Zinc and silver prices are subject to global macroeconomic and geopolitical factors; a sharp decline could impact revenue and margins.
Execution risk on 2x growth capex projects
The 250 ktpa smelter and tailing reprocessing plant involve significant capex and regulatory clearances; delays could affect growth timeline.
Hedging strategy may limit upside
Hedging 10%-20% of volumes at lower prices (e.g., silver at $37-$39/oz) could cap gains if prices continue to rally.
Mine development cost inflation
As mines go deeper, mine development costs are increasing (15 km vs 14 km YoY), which could pressure cost structure if not offset by efficiencies.
Lease expiry of major mines by 2030
Rampura Agucha and Zawar mines have leases expiring in 2030, accounting for 65% of current output. Auction terms and royalty impact are uncertain.
Execution risk in expansion to 2 million tons
Management plans to double capacity to 2 million tons in 2.5-3 years, but this requires significant capital and regulatory approvals.
Delay in silver business demerger
The demerger is delayed due to government's disinvestment process, potentially postponing value unlocking of $3-4 billion.
Commodity price volatility
Despite recent rally, zinc prices remain sensitive to global demand and supply disruptions, impacting revenue and margins.
LME price volatility and trade tensions
Recent U.S. tariff actions have introduced short-term volatility in zinc and silver prices, which could impact realizations.
Silver production below historical levels
Silver guidance of 700-710 tons is lower than FY24's actual output, constrained by lower grades and a shift to zinc production.
Mine lease renewal uncertainty post-2030
Several key mines (Agucha, Zawar, RD) have leases expiring around 2030; management expressed confidence but no policy clarity was provided.
Cost guidance may be optimistic
FY26 cost guidance of $1,025-$1,050/ton is higher than Q4's $994/ton; management attributes this to grade normalization, but execution risk remains.
Geopolitical volatility impacting input costs
Rising diesel, propane, chemical, and explosive costs due to global uncertainties could push production costs above guidance.
Silver production constrained by zinc price dynamics
Higher zinc prices incentivize zinc maximization over lead-silver production, limiting silver output growth despite strong silver prices.
Hedging losses on silver and zinc
Hedging at lower prices resulted in a delta loss of ₹1,100 crore in Q4 and ₹1,500 crore for FY26, reducing potential revenue upside.
Execution risk in expansion projects
Delays in commissioning the Hot Acid Leaching plant (now Q2 FY27) and the 1 million ton smelter plan could impact growth timelines.
