Nyrstar (Trafigura)

Phase A — Understand the business

Lens 1 · Company Overview

What it is. Nyrstar is one of the world's larger merchant zinc and lead smelting groups — it buys mined zinc/lead concentrate and refines it into metal, earning primarily on the treatment charge (TC): the per-tonne fee a miner pays a smelter to convert concentrate to metal, plus recovery of by-product metals (silver, gold, copper, and — the pivot — antimony, germanium, indium). It is a tolling/processing business, not a mining business (post the US sale it retains essentially no captive mine feed), which makes it a price-taker on both concentrate cost and metal price and a taker on the TC — a structurally thin, cyclical margin. Created 2007 by merging the zinc assets of Zinifex (Australia) and Umicore (Belgium); listed on Euronext Brussels; acquired by Trafigura in 2019 via a debt-for-equity restructuring (Lens 9).

Ownership. The operating business ("NN2 Newco") is ~98%+ owned by Trafigura Group Pte Ltd — the private Singapore-based commodity trader. The listed Nyrstar NV retains a small residual economic interest but no operating control. Effectively: Nyrstar is a captive smelting arm of Trafigura, and Trafigura both markets its metal and supplies much of its concentrate — the ultimate related-party structure (Lens 10).

Assets after the US divestment (all ``, 2025–2026):

• Australia — Hobart Zinc Works (Tasmania), an electrolytic zinc smelter; Port Pirie (South Australia), a primary lead smelter / multi-metals facility (Australia's only lead refinery). ~1,400 Australian employees; Hobart cut output 25% from April 2025; Port Pirie is the antimony by-product host. ~900 positions directly tied to Port Pirie (>800 direct + ~250 contractors, figures overlap across reporting).
• Europe — Budel (Netherlands, HQ, ~300kt/yr electrolytic zinc), Balen/Overpelt (Belgium, zinc + alloys), Auby (France, ~172kt/yr electrolytic zinc). Fully electrified → exposed to European power prices; repeatedly curtailed (up to 50%) on energy costs since 2021.
• United States — SOLD to Korea Zinc, completed 1 April 2026. Clarksville TN (the only primary zinc smelter in the US, ~50 yrs old) + East/Middle Tennessee mines. Trafigura continues to market Clarksville's zinc and supply its concentrate/oxide through 2026 under a transition agreement.
• Total group employees ~4,000.

Contract structure / payment terms. Revenue = (metal sold at LME − concentrate purchase cost) + treatment charges + by-product credits − energy/labour/reagents. No take-or-pay recurring contracts; margin is re-set annually by the benchmark TC negotiation (Korea Zinc↔Teck sets the reference) plus spot. Concentration risk is on the input side and the parent side: Trafigura is both counterparty and owner.

Lens 2 · Supply Chain

Named-stakeholder map (`` throughout):

Upstream (concentrate suppliers → Nyrstar). Zinc/lead concentrate is bought on the open market and, critically, from Trafigura's own trading book — Trafigura sources globally (Teck, Boliden, Vedanta, Newmont/Peñasquito, MMG, Glencore third-party tonnes) and on-sells to Nyrstar. Post-US-sale Nyrstar has almost no captive mine feed (the Tennessee mines went to Korea Zinc), so it is ~fully merchant — maximally exposed to concentrate scarcity. Benchmark TC counterparties are the miners; the 2024 benchmark ($165/t) and 2025 benchmark ($80/t) were set in the Teck ↔ Korea Zinc negotiation.

Midstream (Nyrstar smelting). Concentrate → roasting/leaching/electrolysis (zinc) or sinter/blast furnace + refining (lead at Port Pirie) → SHG zinc metal, lead metal, alloys, sulphuric acid, and by-products: silver, gold, copper, cadmium, indium, germanium (Hobart target), antimony (Port Pirie, live since Feb 2026), bismuth/tellurium (studies). The by-product recovery circuit is the entire critical-minerals story — these metals ride out of the existing lead/zinc process, so the incremental capex is a bolt-on, not a greenfield.

Downstream (Nyrstar → end customer). Metal is marketed by Trafigura (again the parent) into galvanizing (steel — the dominant zinc end-use, ~60% of demand), die-casting, batteries (lead-acid), brass/alloys; by-products flow to semiconductors/optics (Ge, Ga), flame retardants + defence + solar (Sb), electronics (In, Bi). US Clarksville zinc is marketed by Trafigura through 2026 even post-sale.

Chokepoints / single-source dependencies. (1) Trafigura is a single point of dependence on both ends — supplier of concentrate and marketer of metal and owner and lender. (2) European power — Budel/Balen/Auby are electricity-cost hostages; a power spike curtails them within days. (3) The benchmark TC — a single annual number, set by other parties, largely determines whether the smelters are cash-positive. (4) Concentrate availability — the 2024 spot TC went negative (−$50 to −$20/t cif China, Aug 2024), i.e. smelters briefly paid miners for the right to process, a direct margin-killer for a pure merchant like Nyrstar.

Lens 3 · Competitive Advantages (moats)

Blunt read: the moat is thin-to-absent at the asset level, and situational at the strategic level.

• Cost-curve position — POOR. Nyrstar's European smelters are among the higher-cost, most power-exposed in the world (fully electrified, EU carbon-cost pass-through, no indirect-cost compensation parity vs non-EU). Its Australian smelters are loss-making enough to require A$240m of government money to stay open. A smelter with no cost advantage and no captive feed has negative durable moat — it is the marginal tonne that shuts first in a downcycle. Contrast Boliden, which owns mines (Tara, Aitik) feeding its own smelters (Odda, Rönnskär) and runs an 18%+ EBITDA margin.
• The one real, but externally-granted, moat: irreplaceability as Western sovereign infrastructure. Clarksville was "the sole primary zinc smelter in the US"; Port Pirie is "Australia's only lead refinery"; Hobart could be the West's germanium source. You cannot quickly rebuild a smelter (Korea Zinc's replacement won't reach commercial ops until 2029). That scarcity is why three governments are paying to keep the doors open. But this is a moat the state confers, not one the company earned — it is a subsidy-dependent option, not pricing power. It converts to value only if (a) governments keep paying and (b) the critical-minerals by-products actually ramp and sell.
• Bargaining power — WEAK on commercial terms, STRONG on political terms. Over suppliers/customers: weak (price-taker, and its counterparty is its own parent). Over governments: currently strong — "close us and you lose your only domestic smelter" is real leverage, evidenced by two bailout tranches in ten months.

Verdict on moat: the durable competitive advantage is near-zero economically; the entire bull case rests on a policy moat (Western supply-chain security) that is contingent, subsidised, and — per Lens 12 — partially undermined by China lifting its export ban in Nov 2025.

Lens 4 · Segments

segments.csv is empty (headers only) — no research-layer segment data exists; the operating business does not publish segment P&L. All figures /, coarse:

Trend: the segment mix is being actively shrunk (US sold, Europe curtailed) and re-pointed from bulk zinc toward higher-value by-product critical minerals — but that transition is 1–3 years from meaningful revenue and gated on government-funded feasibility studies. n/a — not disclosed on any segment-level revenue/EBITDA split.

Phase B — Measure performance

+private note: Phase B swaps the operating-battery's consensus-beat framing for funding/valuation trajectory + traction, since there is no reported quarterly P&L, no consensus, and no stock.

Lens 5 · Funding & valuation trajectory (+private swap for "Earnings Result")

There is no earnings print. The relevant "result" is balance-sheet solvency and the subsidy drip:

• Negative equity. Nyrstar's FY2024 statutory accounts (published Apr 2025) showed negative equity of €−8.4m and the H1-2025 accounts (Sept 2025) a debt-to-equity ratio of −124.4%. Reading: the entity is technically balance-sheet insolvent and solvent only because Trafigura stands behind it. (Absolute debt figures in the public stubs are unreliable/immaterial because most funding is intercompany Trafigura lending — n/a — not disclosed on a clean net-debt number.)
• Loss-making, confirmed by the parent. Trafigura's own 2026 half-year commentary states Nyrstar "remained loss-making" and operated "in highly difficult market conditions".
• The de-facto capital raises are government bailouts, not equity rounds:
• Aug 2025 — A$135m (Federal A$57.5m + South Australia A$55m + Tasmania A$22.5m).
• Jun 2026 — A$105m successor tranche after the first expired 1 May 2026.
• Cumulative A$240m+ three-government support in ten months.
• US$80m Port Pirie modernisation investment tied to competitiveness/critical-metals.
• The real "valuation event": the US asset sale. Nyrstar monetised its best assets — Clarksville + the TN mines — to Korea Zinc, completed 1 April 2026, for an "undisclosed sum". This is the single largest cash inflow and simultaneously the removal of the crown jewel. n/a — price not disclosed (the buyer's new-build is $6.6bn capex/$7.4bn all-in, but that is greenfield, not the price paid for Nyrstar's existing assets).

Balance-sheet flags: negative equity, intercompany-funded, subsidy-dependent, actively selling assets. This is a distressed-going-concern profile, not a growth-round profile.

Lens 6 · Founder / management voice (sentiment trend) (+private swap for "Earnings Calls")

No earnings calls. Proxy signal = Trafigura's public framing + government/company statements over time:

• 2019 (acquisition): Trafigura frames Nyrstar as a distressed rescue and "very substantial shareholder dilution".
• 2021–2024: repeated European curtailment announcements — the tone is defensive/reactive (energy, TCs).
• 2025: Hobart 25% cut "in direct response to deteriorating market conditions and financial losses" (Mar 2025); first bailout (Aug 2025). Tone shifts to "critical minerals to Western allies" — a deliberate re-narration from "loss-making smelter" to "sovereign strategic asset" to justify subsidy.
• 2026: first commercial antimony shipment (Feb 2026) framed as a milestone; US sale completed (Apr); second bailout + a mandated Joint Review with the three governments to set "the long-term pathway" and a pre-feasibility/feasibility study on critical-minerals production (Jun 2026).

Sentiment trend read: management/parent language has migrated from apologetic-curtailment → strategic-sovereignty. The "Joint Review" language is the tell to watch — governments are no longer writing blank cheques; they now want a defined pathway, i.e. the subsidy is becoming conditional. What they've stopped saying: any pretence that the smelters are viable on unsubsidised commercial economics.

Lens 7 · Cap table & peer marks (+private swap for "Comps")

Cap table: trivial — ~98%+ Trafigura, residual listed Nyrstar NV stub. No tier-1 VC syndicate, no crossover funds, no secondary market (it's a subsidiary). The only "syndicate" that matters is the Trafigura balance sheet + three sovereign governments — an unusual but genuinely IPO-proximity-negating cap table.

Peer comparison (economic scale, since no multiples exist for a private): multiples on Nyrstar itself = n/a (private, negative equity, no traded security). Peer set for context (``, 2025–2026):

The comp table's message: the survivors in zinc smelting are integrated (own the mine that feeds the smelter, capturing the mining margin when TCs collapse). Nyrstar, having sold its US mines, is now the least-integrated, highest-cost, only-loss-making name in the peer set. Its relative position deteriorated with the very transaction (US sale) that raised cash.

Lens 8 · Funding / product / price catalysts (+private swap for "Stock-Price Catalysts")

Events that moved the story (no stock to move; ``):

• Jul 2019 — Trafigura restructuring completed; Nyrstar becomes a Trafigura subsidiary (bondholders recover ~50c).
• 2021 / 2022 — European energy crisis; up-to-50% curtailments, Budel care-and-maintenance episodes.
• Mar–Apr 2025 — Hobart −25%; FY24 negative-equity accounts published.
• Aug 2025 — first A$135m three-government bailout.
• Dec 2025 — Korea Zinc agrees to buy Nyrstar US + announces $6.6–7.4bn TN super-smelter with US Dept. of War / Commerce / CHIPS Act / JPMorgan backing.
• Feb 2026 — first commercial Australian antimony shipment from Port Pirie.
• 1 Apr 2026 — US sale to Korea Zinc completed.
• Jun 2026 — second A$105m bailout + mandated government Joint Review.

Pattern: the value inflections for Nyrstar are policy and transaction events, not commodity beats — bailouts, a sovereign-backed divestment, and a subsidy review. This name trades (conceptually) on government decisions and Trafigura's capital allocation, far more than on the zinc price.

Phase C — Judge people & books

Lens 9 · Management

• Structure. Nyrstar sits inside Trafigura's Operating Assets division, created Oct 2024 and led by Jiri Zrust. Group-level authority is Richard Holtum, Trafigura CEO (took over as group CEO in the 2024–25 leadership transition from Jeremy Weir). Matt Howell is CEO of Nyrstar Australia — the operating face for the bailout negotiations. There is no independent Nyrstar plc board with skin in the game — governance runs up into Trafigura's private partnership.
• Track record. Trafigura is a genuinely elite commodity trader (2024/25 annual results described as "strong and steady"; one of the largest metals/energy traders globally). But its record as an industrial-asset operator is mixed-to-poor — Nyrstar has been loss-making for much of Trafigura's ownership and required state rescue. Trading ≠ smelting; the skill that made Trafigura rich (moving molecules and managing basis risk) is not the skill that turns a high-cost smelter cash-positive.
• Skin in the game / ownership. ~98%+ Trafigura ownership → total alignment of the parent, but no public minority to protect and no insider-ownership signal to read (insider-transactions.csv n/a). The relevant question is not "do managers own stock" but "how long will Trafigura fund losses before it walks?" The US sale answers part of it: Trafigura will monetise and exit the pieces it can (US → Korea Zinc) and externalise the losses it can't (Australia/Europe → taxpayers).
• Capital-allocation history. The defining moves: (1) 2019 debt-for-equity takeover at a distressed price — shrewd for Trafigura, brutal for old bondholders/shareholders; (2) years of curtailment rather than closure — optionality preservation; (3) 2026 sale of the best assets (US) to a better-capitalised strategic (Korea Zinc) — rational asset-rotation, but it hollows out the residual; (4) leaning on governments to fund the rump. This is competent parent-level capital allocation that is value-extractive from Nyrstar-the-standalone-entity — Trafigura keeps the trading flows and offloads the industrial risk.
• Founder vs professional manager. Neither — it's a subsidiary of a private trading house. Implication: decisions optimise Trafigura group economics (concentrate flow, metal marketing, risk-shedding), not Nyrstar minority value. Any outside stakeholder in Nyrstar is a passenger on Trafigura's steering.
• Red flags: the entire operation is one giant related-party structure — the owner is also the concentrate supplier and the metal marketer (Lens 10). Plus the parent's own conduct record (below) is materially adverse.

Lens 10 · Forensic Red Flags

financials.csv empty; no filings on disk. Forensic read is structural + parent-level (``):

1. Related-party everything (the headline forensic flag). Trafigura owns Nyrstar, supplies its concentrate, markets its metal, and lends it money. Transfer pricing on concentrate purchases and metal offtake is effectively unobservable to any outside party — margin can be located wherever the group prefers it for tax/optics. For an outside analyst this makes Nyrstar's standalone P&L close to uninterpretable without Trafigura's internal books. Treat any standalone Nyrstar profitability figure with maximum skepticism.
2. Negative equity / going concern. €−8.4m equity (FY24), −124.4% D/E (H1-25). Solvent only via parent support letters. A going-concern dependency on a single related party.
3. Subsidy-as-revenue. A material share of what keeps the Australian sites cash-neutral is government grants (A$240m+), not operating cash flow — a non-recurring, politically-contingent income source dressed into the P&L.
4. By-product accounting optionality. As the antimony/germanium pivot ramps, watch for by-product credits being used to flatter smelting economics; the metals are real but small, and their recovery cost allocation is discretionary.

Regulatory findings (required sub-section). Read companies/nyrstar/regulatory/regulatory-findings.md (Step 0 output):

• SEC (EDGAR EFTS — LR + AAER): total_sec_findings: 0. Nyrstar has no CIK, is private, and is not required to file — no EDGAR enforcement search possible.
• 10-K Item 3 (Legal Proceedings): n/a — no 10-K exists (private).
• Non-SEC / parent-level (web search — material and adverse):
• Trafigura convicted of bribery in Switzerland, 31 Jan 2025 (Angola oil contracts): Swiss Federal Criminal Court (Bellinzona) fined Trafigura CHF 3m (~$3.3m) over ~$5m paid to a foreign official and ordered it to set aside $145m for compensation claims; ex-COO Mike Wainwright convicted (32-month sentence, 12 to serve). First-ever Swiss conviction of a company for foreign bribery.
• Trafigura ~$1.1bn Mongolia fraud provision, Oct 2024: internal + forensic review found employees manipulated data to inflate payments/conceal debts over ~5 years in its Mongolian petroleum unit; ~$143.7m of allegedly corrupt profit.
• (Historically Trafigura also settled the 2006 Côte d'Ivoire Probo Koala toxic-waste matter — legacy, but part of a pattern.)
• Nyrstar-specific enforcement: no material regulatory/legal action found against the Nyrstar operating entity itself via web search as of 2026-07-06.
• Net: No enforcement action against Nyrstar, but the controlling parent has a live, recent, adjudicated corruption record ($1.1bn fraud provision + a criminal bribery conviction inside 24 months). For a wholly-owned subsidiary whose every commercial term is set by that parent, this is a first-order governance red flag, not a footnote.

---

Phase D — Project & stress-test

Lens 11 · IPO-readiness & path-to-tradeable (+private swap for "Forward Projection")

Path to a tradeable security: effectively nil on any near horizon. Reasons:

• Nyrstar is a Trafigura subsidiary, not a pre-IPO independent. There is no S-1 path, no crossover round, no secondary market. Trafigura's disposition strategy is visibly to sell/partner assets piecemeal (US → Korea Zinc) and run the rest — not to IPO Nyrstar.
• The residual entity is negative-equity and loss-making — un-IPO-able as-is.
• The only routes to "tradeable exposure" are indirect: (a) buy Korea Zinc (KRX:010130) — which now owns the actual US Ga/Ge crown jewel and the US-government backing; (b) buy an integrated peer (Boliden, Nexa) for clean listed zinc-smelter exposure; or (c) trade zinc/antimony/germanium directly. Nyrstar itself is not investable by a public-markets participant.

IPO-readiness score (reframed): 1/5 — early/captive, no independence catalyst, structurally not heading to public markets. Milestones that would change this (none imminent): a Trafigura decision to spin/IPO the smelting arm (no signal); the Australian critical-minerals feasibility studies converting to funded, cash-generative antimony/germanium capacity (1–3 yr, gated on the government Joint Review); a full commercial de-subsidy that proves standalone viability (no evidence yet).

Brier forecast (logged conceptually, not via forecast.ts per --watchlist rule): P(Nyrstar operating business lists as an independent public company by end-2028) ≈ 0.05. P(Port Pirie antimony reaches ≥5,000 t/yr run-rate by end-2028 — the company's own target) ≈ 0.40. No forecast.ts row created (breadth-mode rule + no committed base case worth scoring).

Lens 12 · Bull vs Bear

Bull case. Nyrstar is the residual physical Western smelting capacity the US/EU/Australia have belatedly decided they cannot lose. Clarksville was the only US primary zinc smelter; Port Pirie is Australia's only lead refinery; Hobart is a credible Western germanium source. That irreplaceability has already extracted A$240m+ of government money and a sovereign-backed $7.4bn replacement build (for the US assets). The antimony ramp is real and live (first commercial shipment Feb 2026; 2,000→5,000 t/yr path), landing exactly as the West scrambles for non-Chinese antimony (defence, solar). If the by-product critical-minerals pivot converts — germanium/indium at Hobart, antimony/bismuth at Port Pirie — high-cost bulk-zinc smelters get re-rated as strategic critical-minerals refineries with government co-funding and premium by-product pricing. Trafigura's balance sheet backstops it through the cycle. This is a real option — but it is an option on someone else (governments) paying and something unproven (the pivot) working.

Bear case (2–3 permanent-impairment risks).

1. The crown jewel is already gone. The genuinely investable Western Ga/Ge asset (Tennessee) was sold to Korea Zinc. What's left is the high-cost, subsidy-dependent rump. You cannot buy the good part through Nyrstar — and even if you could, you can't buy Nyrstar.
2. China lifted the export ban (Nov 2025). China suspended its Ga/Ge/antimony export prohibition to the US until 27 Nov 2026. The scarcity-panic that drove antimony +~200% and made these by-products strategically precious is partially deflated; if Chinese supply keeps flowing, the price premium underwriting the whole pivot erodes, and the Western-supply-security narrative loses urgency (and with it, political willingness to subsidise indefinitely).
3. Structural cost/TC unviability. These smelters lose money on unsubsidised commercial terms. Zinc TCs collapsed ($274→$165→$80/t 2023→2025) and 2026 benchmark predictions range from negative to low-single-digit positive. A merchant smelter with no captive feed and no cost advantage is the marginal, first-to-close tonne. The A$240m only buys time.
4. Subsidy is now conditional. The Jun-2026 tranche came with a mandated Joint Review — governments want a defined long-term pathway. That is the sound of the cheque-book starting to close.

Pre-mortem (18 months out, thesis broke): it's Jan 2028. The Australian Joint Review concluded the smelters are not viable without permanent subsidy; the government declined a third open-ended bailout after the China export-ban suspension eased critical-minerals anxiety and zinc slid into its forecast surplus; the antimony ramp stalled below target on feed/funding; Trafigura, having already extracted the US sale proceeds and unwilling to fund a bottomless pit, put Hobart and/or Port Pirie into care-and-maintenance. The "critical-minerals refiner" re-rating never arrived because the metals were too small and too late.

Are multiples too high? n/a — no multiple exists. But the implied narrative valuation embedded in headlines ("Western critical-minerals champion") is far too generous relative to the reality (negative-equity subsidised smelter that sold its best asset).

Contrarian view (what the market refuses to see): the market is conflating the buyer's story (Korea Zinc's US-government-backed $7.4bn super-smelter — genuinely exciting) with the seller (Nyrstar). Nyrstar sold the future and kept the liability. The correct trade expression of "Western critical minerals" here is long Korea Zinc / long antimony-germanium exposure, not any notion of Nyrstar as the vehicle.

Lens 13 · Devil's Advocate (short-seller)

Dismantling the bull case:

• What structurally breaks the money-making? It's already broken — the business loses money at the operating level and survives on grants and parent support. There is no unsubsidised path to positive standalone cash flow at current/forecast TCs shown anywhere in the public record.
• Where is revenue concentrated / what if it shifts? Concentrated in bulk zinc (galvanizing/steel demand, cyclical and softening) with by-product credits. The pivot's incremental revenue (antimony ~2,000 t/yr) is small against a multi-hundred-kt zinc base — even at elevated antimony prices it doesn't move the group P&L to profitability alone. And the input (concentrate) and output (metal) both clear through the parent, so "Nyrstar revenue" is a managed number.
• Why is the moat weaker than bulls think? The only moat is government subsidy + irreplaceability — both externally granted and reversible. Governments have signalled conditionality (Joint Review). Irreplaceability is a closure argument, not a pricing-power argument.
• Most dangerous competitor bulls underestimate: (a) China — by resuming exports it removes the scarcity that justifies the whole Western build-out; (b) Korea Zinc — better-capitalised, US-government-partnered, building the modern replacement; it will out-compete the 50-year-old rump on cost and by-product yield from 2029; (c) integrated peers (Boliden/Nexa) that capture mining margin when TCs vanish.
• Worst capital-allocation / governance: the parent's live corruption record (Swiss bribery conviction Jan 2025; $1.1bn Mongolia fraud provision Oct 2024) and the total related-party structure. An outside stakeholder cannot trust the standalone accounts and is subordinate to a parent that has demonstrably had control failures.
• Assumptions that must hold for the (narrative) price: perpetual government subsidy; successful + timely critical-minerals ramp; sustained non-Chinese premium for Sb/Ge/In; Trafigura's continued willingness to fund. Multiple of these are already weakening.
• Growth disappoints 20–30%: for a negative-equity, subsidy-dependent entity, a 20–30% shortfall on the antimony ramp or a lapsed bailout is not a de-rating — it's care-and-maintenance / closure of one or more sites.
• Single scenario that permanently impairs: governments decline the next bailout after China normalises supply → Trafigura mothballs Hobart/Port Pirie. Plausibility: moderate-and-rising given the conditional Jun-2026 tranche and the Nov-2025 export-ban suspension.

Lens 14 · Management Questions (15, ordered by information value)

1. Post-US-sale, what is the standalone, unsubsidised operating cash flow of the remaining Australian + European smelters at the current benchmark TC — i.e. what is the real burn absent government money?
2. On what transfer-pricing basis does Nyrstar buy concentrate from and sell metal to Trafigura, and how much group margin is recognised at Nyrstar vs the trading book?
3. What is Trafigura's hard limit on funding Nyrstar losses — is there a walk-away threshold, and what triggers care-and-maintenance at each site?
4. What did the Joint Review with the Australian governments conclude (or what is its expected finding), and does any government support extend past end-2026?
5. What is the fully-loaded capex and timeline to reach the 5,000 t/yr antimony target and to bring germanium/indium at Hobart to commercial scale — and its expected IRR at today's (post-ban-suspension) metal prices?
6. How does the China export-ban suspension (to Nov 2026) change the price assumptions and the strategic rationale for the by-product pivot?
7. What are the by-product economics — expected annual revenue and margin from antimony/germanium/indium/bismuth — as a share of group revenue at steady state?
8. Why should any capital provider back the residual Nyrstar rather than Korea Zinc, which now owns the US assets and the government backing?
9. What is the decommissioning/rehabilitation liability at Hobart and Port Pirie, and who bears it in a closure scenario?
10. What LME zinc price and TC level are required for each European smelter to run un-curtailed and cash-positive, given EU carbon and power costs?
11. Is a spin-off or IPO of the smelting business contemplated on any horizon, or is piecemeal asset sale (US-style) the template for the rest?
12. What governance changes followed the parent's Swiss bribery conviction and Mongolia fraud — specifically around related-party controls affecting Nyrstar?
13. What are the contractual terms of the Trafigura-marketing arrangement for Clarksville zinc through 2026 post-sale, and does any residual Nyrstar economic interest survive?
14. What share of workforce and output is contingent on the next subsidy tranche, and what is the closure sequence if it lapses?
15. What is the plan if zinc moves into its forecast 2026–27 surplus and TCs stay near zero — beyond further government appeals?
