• Total market cap: ~RMB 89.44 billion (RMB 6.67 × 13.409 billion shares, convertible bonds fully converted)
• Margin of safety: -28% (base-case fair floor of RMB 4.8 vs. current price); probability-weighted fair value ~RMB 5.61, current price ~19% above it
• 52-week range: RMB 4.23–9.19 (current price down 27% from the peak, +14.6% YTD)

I. Summary of Key Conclusions

Tongling Nonferrous Metals is China's second-largest copper smelter (1.9548 million tonnes of cathode copper in 2025), with mine self-sufficiency of only ~10%; its earnings essentially consist of a combination of "smelting treatment charges + price elasticity of self-mined copper + sulfuric acid/gold-silver by-products." 2026H1 net profit attributable to the parent of RMB 2.993 billion (+107.9%) hit a record high, but this is a cyclical peak reading, occurring when the LME copper price sits at the 100th historical percentile, long-term TC has gone to zero, and by-product prices have surged: operating cash flow for the same period was only RMB 54 million, free cash flow has been negative for three consecutive years, and RMB 38.5 billion of inventory (35.2% of total assets) took RMB 2.4 billion of impairment charges. Using a mid-cycle copper price of USD 11,500–12,500, normalized net profit is ~RMB 5.5–6.2 billion, implying a base-case fair value of RMB 4.8–6.4; the current price of RMB 6.67 is ~19% above this, with valuation at historical highs (PB near the 95th percentile of the past 10 years) but not extreme. The core variable is the Mirador Phase II Mining Contract—construction is complete yet it remains suspended due to Ecuador's political situation; it is both the largest option and the largest overhang on valuation. Given both quality (ROIC ~4.7%, below cost of capital) and price (modestly overvalued, no margin of safety), we assign Neutral (Hold): do not chase the rally; wait for valuation digestion from a copper price pullback or option realization from a Phase II contract signing.

II. Investment Opportunity Assessment

Three things that will genuinely change in the next 6–12 months: ① Copper price path—The ICSG balance has flipped to a small surplus in 2026 (96,000 tonnes) with an expanding surplus in 2027 (377,000 tonnes); Goldman Sachs forecasts a 2026 average price of USD 12,650 and raised its year-end forecast to USD 13,735 in August; bullish and bearish evidence coexist and direction is undetermined. ② Mirador Phase II Mining Contract—negotiations on the text are complete but stalled on Ecuadorian politics and approval processes; signing would eliminate the largest overhang (probability ~0.55, 2026Q4–2027H1). ③ 2027 long-term TC negotiations (settled in 2026Q4)—after TC went to zero for the first time in history in 2026, CSPT production cuts of 10%+ may force a recovery window for TC.

Ranking of primary stock price drivers: Copper price path (197,700 tonnes of self-mined ore × ±USD 1,000/tonne ≈ ±RMB 1.0–1.2 billion net profit, while also determining the direction of inventory impairment/reversal) > Mirador Phase II signing > TC/RC negotiations.

Expectation gap: Sell-side coverage is extremely thin (only 1–3 firms), with contradictory estimates—THS shows 3 firms at ~RMB 5.735 billion for 2026E net profit; Guosen Securities at RMB 7.02/11.08/11.43 billion for 2026–2028E (assuming RMB 105,000/tonne copper through 2028); investing.com shows 1 firm with a target of RMB 5.00. This report's base case (copper price falling back to a USD 11,500–12,500 center, Phase II signed in 2027 with ramp-up in 2028) corresponds to 2027–28E net profit of RMB 5.5–6.8 billion—within the market's distribution range, at the conservative end. The expectation gap state is mixed: the market has partially priced in peak normalization, but the bullish narrative that "the copper price center has systematically shifted up due to supply deficits" is backed by the IEA's 30% gap by 2035; neither side has a certainty anchor.

Validation catalysts: Formal signing announcement of the Phase II mining contract (the only valid confirmation); impairment reversals and OCF repair in the 2026 Q3 report; results of 2026Q4 long-term TC negotiations. Falsification conditions: LME quarterly average holding above USD 13,000 through 2027 (peak normalization becomes reality, falsifying this report's center assumption); or copper price breaking below USD 9,000 combined with another Phase II delay (bear case realized).

III. Investment Thesis

C1 — Weak earnings quality: book profits not converted into cash (Confidence 0.75)

2026H1 net profit attributable to parent was RMB 2.993 billion, while operating cash flow was only RMB 54 million (OCF/net profit 0.02); OCF/net profit deteriorated from 2.40 in 2023 to -0.09 in 2025; free cash flow was negative for 2024/-2.97 billion, 2025/-3.42 billion, 2026H1/-4.35 billion. Profits have accumulated largely in inventory (RMB 38.46 billion, 35.2% of total assets), and during the copper price surge the company took RMB 2.40 billion in inventory impairment provisions (reducing total profit by RMB 2.113 billion, ~71% of attributable net profit for the period).

Key evidence:

• Tongling Nonferrous 2026 interim report, consolidated cash flow statement: "Net cash flow from operating activities 54,389,983.22" (RMB 0.054 billion vs. RMB 2.993 billion attributable to parent)
• Tongling Nonferrous "Announcement on Provision of Asset Impairment" 2026-08-28: "Inventory impairment provisions of RMB 2,399.2117 million this period, write-offs of RMB 260.1856 million… total reduction of reported profit of RMB 2,112.6002 million"
• Tongling Nonferrous 2025 annual report, cash flow change explanation: OCF -RMB 227 million (-116.35%), "mainly due to substantially increased inventory this period"

It should be noted that inventory expansion has a passive component from rising copper prices (SHFE copper +31.4%) and production/sales expansion; a substantial portion of the RMB 2.4 billion impairment is the inventory-based clearing of smelting losses on purchased concentrate under negative TC and constitutes conservative provisioning; the RMB 2.614 billion of closing impairment provisions constitutes a reversal option at high copper prices. But the balance sheet structure of "profits that don't generate cash + rolling expansion of RMB 34.36 billion in interest-bearing debt" will be severely penalized by the market in a downturn—this is the core quality-level discount.

C2 — The 2026H1 profit doubling is a cyclical peak reading, not a sustainable center (Confidence 0.70)

All three earnings pillars are at cyclical highs: ① On smelting TC, 2026 copper concentrate long-term TC/RC went to zero for the first time in history and spot TC is deeply negative (reported range USD -40 to -88/tonne), meaning smelting of ~1.76 million tonnes of purchased concentrate is "loss-making on core smelting"; ② mine self-sufficiency is only ~10.1% (197,700/1,954,800 tonnes), so each ±USD 1,000 in copper price affects net profit by ~±RMB 1.0–1.2 billion; ③ on by-products, sulfuric acid gross margin is 75.6% and gold/silver prices are at historical highs, making them the main profit source of the smelting segment. The current LME copper price of ~USD 14,200 sits at the 100th historical percentile and has never held that level for more than a quarter; the 2026H1 SHFE copper average of RMB 101,964/tonne (~USD 12,700) is already in the high range.

Key evidence:

• Tongling Nonferrous 2026 interim report, MD&A: "Long-term copper concentrate TC went to zero this year, spot TC fell deeply negative, smelting processing income was substantially eroded… by-products such as sulfuric acid and precious metals ran at high prices and became the main profit source of the smelting segment"
• Tongling Nonferrous 2025 annual report: 2025 revenue +18.69%, attributable net profit -14.02%—"revenue up but profit down" in a rising copper price year (Note: the company attributes this mainly to a one-off income tax increase of +112.57% due to adjusted dividend arrangements of overseas subsidiaries, but the structural backdrop of low TC squeezing smelting margins is real)
• ICSG 2026-04 forecast: refined copper surplus of 96,000 tonnes in 2026 and 377,000 tonnes in 2027; Goldman Sachs 2026 average price forecast of USD 12,650 with an expected pullback from highs

C3 — Mirador Phase II is the core valuation option, but realization is suspended (Confidence 0.55)

Phase II construction is essentially complete (cumulative investment of RMB 4.478 billion), originally planned to start up in early 2026, but due to Ecuadorian political turbulence and frequent personnel changes at the responsible authorities, the Mining Contract remained unsigned as of August 2026 and the startup timing is undetermined. If signed: Phase II at full capacity would add ~100,000–140,000 tonnes/year of mined copper (Phase I+II combined design capacity ~200,000 tonnes of copper metal/year, 46.2 million tonnes/year of mining and processing), lifting company self-sufficiency from ~10% to 15–25%; annualized incremental attributable profit at full capacity of ~RMB 1.0–2.5 billion (70% equity basis; requires deducting the additional extraction under Ecuador's "government take no less than 52% of total revenue" backstop clause, with a 2–3 year ramp-up). Guosen measured Mirador Phase I at ~RMB 36,000 net profit per tonne in 2026H1, with Phase II mining/processing costs ~70% of Phase I—the per-tonne profit assumption is not aggressive.

Key evidence:

• Tongling Nonferrous 2026 interim report, major subsidiary matters: "No further material progress on signing of the Mining Contract; it remains unsigned, and Phase II startup timing is temporarily undetermined"
• SZSE Interactive (互动易) 2026-08-31: "Phase II formal startup can only proceed after its Mining Contract is signed… Phase I and Phase II of the Mirador copper mine will together have a copper ore processing capacity of 46.2 million tonnes/year, with design capacity expected to produce copper concentrate corresponding to ~200,000 tonnes of copper metal per year"

C4 — Current price is above mid-cycle fair value, but only modestly (Confidence 0.60)

Based on assumptions of a mid-cycle copper price of USD 11,500–12,500, TC recovering to USD 30–50, and by-products falling from highs, normalized attributable net profit is ~RMB 5.5–6.2 billion (EPS ~RMB 0.41–0.46), implying a base-case fair value of RMB 4.8–6.4 (2027–28E EPS RMB 0.41–0.51 × 11–13x). The current price of RMB 6.67 is ~19% above the base-case midpoint and ~19% above the probability-weighted fair value (~RMB 5.61), modestly above the upper end of the base range. PB of 2.35 sits at the 95th percentile of the past 10 years (94th over 5 years), but only the ~41st percentile within the copper sector (sector median 2.6x)—valuation is at historical highs but not extreme within the sector; PE(TTM) of 22.55x is at a cyclical earnings high, so its percentile is for reference only. Sensitivity note: each ±USD 2,000 shift in the mid-cycle copper price anchor changes normalized net profit by ~±RMB 2.0 billion and moves the fair value range by ~±RMB 1.5–2—this report's conclusions are highly sensitive to the copper price assumption, which is the essence of our divergence from the market.

Key evidence:

• This report's scenario analysis (copper price sensitivity: 197,700 tonnes self-mined ore × USD 1,000 × FX 7.1 × 1.13 VAT × 75% after-tax ≈ RMB 1.19 billion, ~RMB 1.02 billion after minority interest share)
• This report's valuation data (2026-08-31): PB 2.35 (95th percentile, 10-year); PE(TTM) 22.55 (75th percentile, 5-year)
• Sell-side anchors: Guosen Securities on 2026-08-30 gave 2027E attributable net profit of RMB 11.08 billion (implying 8.2x); consensus FY2027 forward PE ~10x; Jiangxi Copper TTM 14.4x—this report's 11–13x exit multiple takes the mid-cycle lower end between peers and history

C5 — Real hedges exist, but their magnitude is insufficient to reverse the risk-reward (Confidence 0.55)

Three positive hedges: ① Inventory impairment reversal—closing impairment provision balance of RMB 2.614 billion; at copper prices of USD 13,000–14,000, ~40–50% qualifies for write-off, with after-tax profit elasticity of ~RMB 0.8–0.9 billion; ② Tongguan Copper Foil's HVLP high-end products ramping—AI-server-driven high-end copper foil demand +260% in 2026, processing fees raised 30–50%, attributable profit elasticity ~RMB 0.2–0.3 billion/year, plus the "AI materials" narrative carries option value on valuation; ③ the H-share issuance builds an internationalization platform. However, the H-share issuance also brings ~9–13% potential dilution and A/H price spread pull (A shares fell 3.55% the day after the announcement); net of offsets, these hedges cannot fill the ~19% premium of the current price over mid-cycle fair value.

Key evidence:

• Tongling Nonferrous "Preliminary Announcement on Planning an H-Share Issuance and Listing on the Main Board of the Hong Kong Stock Exchange" 2026-09-01: "Relevant details have not been determined… there is considerable uncertainty as to whether it can pass deliberation, filing, and review procedures and ultimately be implemented"
• Tongling Nonferrous 2026 interim report, core competitiveness analysis: "Successfully broke foreign technological and market monopolies on key products such as heat-resistant oxygen-free copper strip and HVLP series copper foil"; annual copper foil capacity of 80,000 tonnes
• SZSE Interactive 2026-06-26: "When inventory with impairment provisions is subsequently sold externally, the provisions will be written off simultaneously, reducing current operating costs and thereby positively repairing current profit"

IV. Core Financial Data and Latest Earnings Review

Note: For stock items (cash + cash-like assets, interest-bearing debt, debt-to-asset ratio), the 2026H1 column reflects 2026-06-30 balance sheet figures; certain 2026Q1 items were not separately disclosed and are marked "—".

Reasons for metric changes (YoY ≥ ±20%):

• 2026H1 revenue +59.98%: increased production/sales volumes of main products and rising sales prices (SHFE copper spot average RMB 101,964/tonne, +31.4% YoY)—company interim report income statement change analysis
• 2026H1 attributable net profit +107.93%: rising copper prices, high by-product (sulfuric acid/gold-silver) prices, and rising copper foil processing fees acting in concert
• 2026H1 asset impairment losses -RMB 2.399 billion (vs. -RMB 95 million prior year): increased inventory impairment provisions; impairment announcement confirms RMB 2.113 billion reduction in total profit
• 2026H1 investment income -RMB 212 million (-488%): increased losses on derivatives unwinding
• 2026H1 finance costs +153.95%: reduced FX gains
• 2026H1 minority interest income RMB 1.105 billion (+791%): CRCC-Tongguan (Mirador, 70%-owned) net profit of RMB 2.185 billion on higher volumes and prices
• 2025FY attributable net profit -14.02%: adjusted dividend arrangements of overseas subsidiaries drove income tax expense +112.57% (one-off tax factor)
• 2025FY operating cash flow -116.35%, turning negative: substantially increased inventory (inventory +65.29% to RMB 30.781 billion)
• 2026Q1 recurring net profit -50.27% vs. attributable +19.12%: non-recurring gains of +RMB 780 million (including +RMB 929 million in derivative fair value changes), causing divergence between attributable and recurring profit

Latest Earnings Review (2026H1)

2026H1 revenue was RMB 121.715 billion (+59.98%), attributable net profit RMB 2.993 billion (+107.93%), recurring profit RMB 3.071 billion (+119.44%)—all record highs, falling in the upper-middle of the July 14 profit preannouncement range (RMB 2.65–3.15 billion), with Q2 attributable net profit of RMB 1.654 billion rising sequentially. Versus market expectations: sell-side coverage is extremely thin; 3 institutions on THS estimate ~RMB 5.735 billion for 2026E attributable net profit—H1 has achieved 52%, with high probability of full-year delivery; Guosen's 2026E of RMB 7.02 billion would require ~RMB 4.0 billion from H2, dependent on copper prices holding near USD 14,000. The results themselves were in line to slightly ahead of expectations, but two discounts must be noted: first, weak earnings quality (OCF near zero; pre-impairment profit higher but not cash-realized); second, the earnings mix includes sulfuric acid (75.6% gross margin) and gold/silver by-products at historically high prices, and large two-way disturbance from inventory impairment/reversal—sustainability of single-quarter readings is questionable.

V. Business Model and Earnings Quality

Model sketch: Asset-heavy copper smelting as the core (buying concentrate to earn processing fees, cathode copper capacity of 2.2 million tonnes) + owned mines (197,700 tonnes of copper in self-mined concentrate, ~10.1% self-sufficiency) + copper processing/foil (80,000 tonnes capacity, 72.38% control of Tongguan Copper Foil) + by-products (6.2185 million tonnes of sulfuric acid, 20.51 tonnes of gold, 579.55 tonnes of silver). Revenue has no recurring character and the smelting business has no pricing power—TC/RC is set by miners, as evidenced by long-term TC going to zero in 2026; profit elasticity depends on the mining end and by-product prices.

Cash content test of earnings: OCF/net profit attributable to parent for 2023–2026H1 was 2.40 → 0.49 → -0.09 → 0.02; FCF/net profit was 1.39 → -1.06 → -1.41 → -1.45—both breaking below the 0.8/0.5 warning thresholds with deteriorating trends. Interpretation: for a smelter with ~RMB 170 billion in revenue in a year when copper rose +31%, inventory expansion has a passive component, but three consecutive years of negative FCF, interest-bearing debt rising from RMB 21.96 billion to RMB 34.36 billion, and a large gap between cash of RMB 5.25 billion and short-term borrowings of RMB 17.82 billion are hard facts—expansion relies on external financing (share issuance + convertible bonds in 2023, H-share plans in 2026). Recurring earnings test: 2025 recurring profit of RMB 3.461 billion > attributable RMB 2.415 billion (gap mainly from one-off income tax and derivative fair value changes of -RMB 1.706 billion); 2026Q1 attributable RMB 1.338 billion > recurring RMB 559 million (derivatives +RMB 929 million)—attributable and recurring profit repeatedly diverge, so statement predictability is poor. The company's own reported figures show no aggressive add-back issues (SBC not applicable).

Return on capital: Estimated 2025 ROIC ~4.7% (NOPAT RMB 3.526 billion / interest-bearing debt RMB 28.37 billion + equity RMB 46.50 billion), below a 9% WACC—the smelting-dominated earnings structure currently fails to earn the cost of capital; 2025 ROE of 6.8% is also at the low end of the sector (Zijin at 31.8% in the same period).

Maintenance CapEx: CapEx/depreciation was 1.63 in 2024 and 1.06 in 2025—the ratio fell as Mirador Phase II, green intelligent copper-based new materials, and other projects were placed into service in 2025–2026, but 2026H1 CapEx of RMB 4.406 billion (+76%) rose again; the expansion phase is not yet over.

Red flags: ① Inventory of RMB 38.46 billion is 35.2% of total assets, with RMB 2.4 billion of impairment provisions taken in 2026H1; ② derivatives notional position of RMB 33.961 billion, or 89.23% of net assets (RMB 8.206 billion, 22.19% at end-2025), with margin and basis risk amplified by price volatility; ③ minority interests divert profit—CRCC-Tongguan (70%-owned) net profit of RMB 2.185 billion in 2026H1, with minority interest income at 27% of net profit; ④ customer/supplier concentration is not high (top five customers 25.36%, top five suppliers 35.30%)—no concern on this item.

VI. Management Assessment

Consistency between words and actions: ① The 2026-07-14 earnings preannouncement guided for net profit attributable to parent of RMB 26.5–31.5 billion → actual was RMB 29.93 billion, in the upper-middle of the range; delivered. ② Mirador Phase II was originally planned to start production in early 2026 → as of August 2026, the Mining Contract had still not been signed; not delivered (constrained by Ecuador's political situation and not fully within the company's control, but the company already flagged this risk in its 2025 annual report). ③ The 2026 plan for 227,600 tonnes of copper in self-produced copper concentrate and 2.108 million tonnes of cathode copper has not yet come due. Verdict: pragmatic, preannouncement caliber credible; overseas project execution is subject to the external political environment—investors should apply a discount to its timelines.

Shareholder friendliness: Payout ratio 36.9% (2023) → 45.5% (2024) → 55.5% (2025); the 2026 interim dividend proposal is RMB 805 million (RMB 0.6 per 10 shares, 26.9% of H1 net profit attributable to parent), a favorable trend; buybacks of RMB 200 million (0.41%, for convertible bond conversion) are small in scale. On the dilution side, however: 2.140 billion shares issued in 2023 plus convertible bonds to acquire 70% of CRCC Tongguan; +740 million shares from conversions during 2024–2025; and in September 2026, planning for an H-share issuance (size undetermined)—persistent reliance on equity financing. Verdict: dividends improving but expansion relies on external financing; neutral-to-friendly.

Risk signals: ① In June 2025, the dividend arrangement of overseas subsidiary ECSA was adjusted, driving that year's income tax up 112.57% and net profit attributable to parent down 14%—a one-off tax erosion; the company called it "safeguarding capital security." ② In 2026H1, sales of silver ingots to related party Zhongke Tongdu reached RMB 1.352 billion, exceeding the approved quota of RMB 1.2 billion. ③ The Board Secretary concurrently serves as Chief Accountant, conflicting with new regulatory rules; the company says it will "strive to separate the positions." ④ The controlling shareholder's 2.146 billion restricted shares nominally unlock on 2026-09-14, but release is conditional on completion of the 2023–2027 performance commitment assessment (actual selling pressure deferred to at earliest 2027).

VII. Segment Breakdown (2026H1)

Profit drivers: By gross profit, copper products contributed about RMB 6.4 billion (~57%), chemicals (sulfuric acid) about RMB 3.0 billion (~27%), and gold and other by-products about RMB 1.7 billion (~15%)—copper products, at 80% of revenue, remain the largest gross profit contributor by sheer volume, but sulfuric acid, at only 3.3% of revenue, delivered just over a quarter of gross profit with a 75.6% gross margin, serving as the profit pillar of the smelting segment in a zero-processing-fee environment. The gap between the highest and lowest segment gross margins is about 69 percentage points: sulfuric acid is an inevitable co-product of smelting with virtually no incremental raw material cost, while copper product margins have been compressed to 6.6% by TC going to zero—the spread itself is a microcosm of the "mining strong, smelting weak" value distribution. If sulfuric acid/gold and silver prices fall from highs, the smelting segment will lose its main hedge (2025 gross margins: gold and other by-products 22.47%, chemicals 58.78%; both climbed further in 2026H1, highly volatile).

VIII. Accounting Techniques and Cross-Period Consistency

Accounting red flags: ① Abrupt change in inventory write-down provisions (medium): 2026H1 provision of RMB 2.40 billion (2025H1 only RMB 95 million; full-year 2025 RMB 724 million), occurring during a period of sharply rising copper prices, exceeding 30% of the prior year's audited net profit absolute value—investors questioned hidden profits; the company denied this and explained the reversal mechanism. ② Abnormally volatile effective tax rate (medium): 30.9% (2024) → 51.1% (2025) → 37.0% (2026H1), stemming from the one-off tax impact of the ECSA dividend arrangement adjustment. ③ Large swings in derivatives fair-value gains/losses (medium): -RMB 1.706 billion in 2025, +RMB 1.032 billion in 2026Q1; repeated divergence between attributable and non-GAAP (ex-non-recurring) figures. ④ Related-party transactions exceeding quota (low): silver ingot sales to Zhongke Tongdu of RMB 1.352 billion > approved quota of RMB 1.2 billion. ⑤ RMB 1.133 billion of pre-acquisition-date profit from business combination under common control in 2023 non-recurring items (low), inflating current book profit.

Cross-period consistency: ① OCF/net profit attributable to parent: 2.40 → 0.49 → -0.09 → 0.02—the company consistently explained "substantially increased inventories" in each period. ② Inventory/total assets 23.03% → 30.72% → 35.19%, rising year by year—unexplained by the company. ③ Abnormally high effective tax rate—the company's explanation is consistent (overseas dividend arrangement). ④ Minority interest share of net profit: 7.9% → 27.0—no dedicated explanation (inferrable from CRCC Tongguan's profit surge, but that is inference). ⑤ Repeated divergence between attributable and non-GAAP profits—unexplained by the company.

Summary: No classic financial fraud pattern found (no goodwill, low customer concentration, standard unqualified audit opinion), but there are many sources of noise in the financials (derivatives, impairments, tax rate, minority interests); poor earnings predictability is a genuine valuation discount. Inventory (RMB 38.5 billion, 35% of total assets) and the direction of impairment provisions/reversals are items to monitor quarter by quarter.

IX. Resource Stock Deep Dive

Reserves and production: Mine-held copper metal resources of about 7.36 million tonnes (end-2025, company caliber, not classified per JORC/RC standards); 2025 added about 380,000 tonnes of resources, consumed about 238,600 tonnes, a reserve replacement ratio of ~159%; exploration spend of RMB 109 million; in 2026H1, acquired the Jiguanshan–Hucun copper-gold-molybdenum exploration rights (intangible assets +65.33%). Production: copper in self-produced concentrate: 2024 155,200 t → 2025 197,700 t (+27.4%) → 2026 plan 227,600 t; cathode copper 2025 1.9548 million tonnes (No. 2 in China); sulfuric acid 6.2185 million tonnes, gold 20.51 tonnes, silver 579.55 tonnes. Mirador (70% held via CRCC Tongguan): Phases I and II combined mining/processing capacity of 46.2 million tonnes/year, designed for ~200,000 tonnes of copper metal/year; Phase II built but not yet commissioned. The company does not disclose reserves/grade/mine life by mine—insufficient disclosure granularity, pending verification.

Unit economics: C1/AISC/unit full cost not disclosed. TC/RC is the core smelting price—2026 long-term contracts at zero, spot deeply negative (reported range of -$40 to -$88/tonne); the company has not disclosed its realized processing fees. Its position on the cost curve cannot be located; the company says it relies on scale, recovery rates, and comprehensive by-product recovery to hedge the inversion. Mining-side reference: Guosen measured Mirador Phase I at ~RMB 36,000 net profit per tonne in 2026H1; Phase II mining/processing costs are ~70% of Phase I's.

Hedging and price sensitivity: SHFE/LME copper, gold and silver futures + options + forward FX, all exchange-traded, for hedging purposes; notional derivative exposure at end-2026H1 was RMB 33.961 billion (89.23% of net assets); locked volumes and prices undisclosed. Copper price ±10% sensitivity: on a self-produced mine basis of 197,700 tonnes, pretax ~±RMB 2.0 billion; after minority interest sharing and hedging offsets, attributable to parent ~±RMB 1.0–1.2 billion—about ±17–20% of annualized 2026H1 earnings.

Geopolitics and mining rights: Ecuador's political turbulence has kept the Mirador Phase II Mining Contract unsigned (the government system at one point showed "signed," contradicting the company's "no notice received"—confusing information environment); the contract contains a backstop clause that "government take shall be no less than 52% of total revenue" plus an annual payment obligation of 12% of total profit, so the government's extraction rate on incremental profit may exceed the standard tax burden; the Quimi/Tundayme tailings dams are located in a seismically active area, with dam-failure risk warnings (expert reports); Phase I's ~96,000 tonnes account for nearly half of self-produced mine output—if Ecuador's situation affects Phase I, the profit foundation would be shaken. Domestic mining rights renewals are proceeding normally.

NAV perspective: Mining side (7.36 million tonnes resources + 70% Mirador interest): mid-cycle earnings RMB 1.6–1.8 billion × 10–12x ≈ RMB 16.0–21.6 billion; smelting/processing mid-cycle earnings RMB 1.2–1.4 billion × 6–8x (replacement cost basis: 1.95 million tonnes capacity × RMB 5,000–6,000/tonne) ≈ RMB 7.2–11.2 billion; total RMB 23.2–32.8 billion − net debt RMB 27.811 billion ≈ -RMB 4.6 billion to +RMB 5.0 billion, i.e., roughly -RMB 0.34 to +RMB 0.37 per share. Book BVPS of RMB 2.84 is a nominal floor (liquidating smelting assets would carry a large discount, so the realizable floor is lower). The current price of RMB 6.67 is more than RMB 6 above the NAV operating value—the entire premium is a bet on copper prices staying at peak levels and on the Phase II option.

X. Valuation and Odds

Current market data and multiple percentiles (closing price RMB 6.67, 2026-08-31): Market cap RMB 89.44 billion; PE(TTM) 22.55x (75th percentile over 5 years—earnings are at a cyclical high, so percentiles are for reference only); PB 2.35x (94th percentile over 5 years, 95th over 10 years; ~41st percentile within the copper sector); PS(TTM) 0.41x (high smelting revenue share, not pricing-relevant); forward PE (2026E sell-side consensus EPS RMB 0.47) 14.2x. Liquidity normal (average daily turnover ~RMB 1.5–1.9 billion, about 2% of market cap).

Peer comparison:

"Mining feasts, smelting gets the scraps" is evident in the peer table: in the same rising copper price environment, Zijin's ROE is 31.8% vs Tongling's 6.8%; Tongling's PE(TTM) of 22.6x sits at the top of the sector, reflecting precisely its lowest mining share within its earnings structure.

Market-implied expectations: Current market cap of RMB 89.44 billion ÷ 13x mid-cycle reasonable PE ≈ implied normalized attributable profit of ~RMB 6.9 billion—against a 2026H1 annualized base of ~RMB 6.0 billion (SHFE copper average price equivalent to ~USD 12,700), this requires copper to hold at ~USD 12,600–14,700 (excluding Phase II) or ~USD 11,500–12,000 plus a smooth ramp-up of Mirador Phase II. Reality: mid-cycle copper prices of USD 11,500–12,500 correspond to normalized attributable profit of ~RMB 5.5–6.2 billion. Market pricing is somewhat above mid-cycle reality, but the gap is not large—the crux of the disagreement is "whether the copper price center has structurally shifted up due to the supply gap": the IEA warns of a 30% gap by 2035 and Goldman Sachs raised its year-end forecast to USD 13,735 in August (bull evidence), vs the ICSG balance flipping to surplus and the historical fact that 100th-percentile prices have never persisted beyond one quarter (bear evidence).

Three-tier value: Asset floor = book BVPS of RMB 2.84 (NAV operating basis ~RMB 0/share; RMB 27.8 billion of net debt nearly erases mid-cycle operating value); zero-growth EPV = RMB 3.37/share (normalized unlevered EPS of RMB 0.49 ÷ WACC 9% − net debt per share of RMB 2.07; normalized base uses mid-cycle copper at USD 12,000 corresponding to attributable profit of ~RMB 5.9 billion, EPS RMB 0.44, adding back after-tax net interest of ~RMB 0.06); growth option = current price 6.67 − EPV 3.37 ≈ RMB 3.30, about 49% of the current price—roughly half of the current price rests on growth/cyclical options (Mirador Phase II + copper prices holding high), while EPV and the asset floor are both far below the current price; downside protection is thin.

Three scenarios and odds:

Probability-weighted fair value is ~RMB 5.61: the current price is ~19% above it and ~19% above the base-case midpoint; downside to the bear-case midpoint is ~-44%, upside to the bottom of the bull case is ~+14%—odds skew downward but not extremely, with the current price in no-man's-land between the top of the base range and the bottom of the bull case. The anchor for the base-case exit multiple of 11–13x: the mid-cycle lower band between Jiangxi Copper's TTM of 14.4x and the stock's 5-year median PE of 14.6x, cross-checked against Guosen's 2027E 8.2x and consensus forward of ~10x—this report's figure sits between sell-side and the historical center, not self-justified using the company's current multiple.

Conclusion: Modestly overvalued. Target price range RMB 4.8–6.4 (= base-case fair value), margin of safety -28%. Evaluate quality and price separately: the company is a scale survivor in the smelting shakeout holding a genuine mining option, but ROIC is below the cost of capital, earnings do not convert to cash, and the valuation is at a historical high—the current price already embeds fairly optimistic copper price assumptions; the risk/reward is unattractive.

XI. Industry Landscape and Competitive Structure

Market Size: Global refined copper consumption in 2024 was approximately 27.33 million tonnes (+2.9%), with China at 15.95 million tonnes accounting for 58%; China's refined copper consumption in 2025 was approximately 16.58 million tonnes. Based on an estimated 2025 LME average price of roughly USD 9,500–9,600/tonne, the global refined copper market is worth approximately USD 250–260 billion per year (estimate). Over the past 5 years, the midpoint of global consumption growth has been around 2–3%; ICSG forecasts +1.6% in 2026 and +2% in 2027; S&P Global (Jan 2026) projects that electrification will drive copper demand to 42 million tonnes by 2040 (+50% vs. 2024, implying a CAGR of roughly 2.5%), while the IEA warns that, based on the current project pipeline, the supply gap will reach 30% by 2035. Demand momentum is shifting: the real estate chain's share is declining, with grid investment (the largest single source of domestic demand), new energy vehicles (~80kg of copper per vehicle, 3–4x that of combustion-engine cars), solar/wind, and AI data centers taking over. To be transparent: the copper intensity per MW in AI data centers is significantly higher than in ordinary buildings (the industry commonly cites 25–40 tonnes/MW), but no verifiable primary unit-consumption data was found in this report; AI copper demand currently remains a low-single-digit percentage of global demand—the narrative of "AI repricing copper demand" holds qualitatively, but the quantitative chain awaits verification, and as a smelting-plus-processing company, Tongling Nonferrous has no exclusive positioning in AI-driven incremental demand; its real share variable lies in mining (Mirador Phase II).

Industry Chain and Value Distribution: Mining and beneficiation (mine end) → smelting (TC/RC model) → copper processing → end markets. The mine end is the most profitable link in the entire chain—global mining is highly concentrated (the top 10 mines account for over one-fifth of global mined copper, dominated by BHP/Codelco/Freeport/Glencore), and the 2025–2026 copper concentrate shortage has pushed mines' bargaining power over smelters to an extreme (as marked by long-term TC contracts falling to zero and negative spot values); the smelting segment is technologically mature and capital-intensive but prone to overcapacity, with China's refined copper output of 13.64 million tonnes accounting for 43% of the global total; the processing segment is highly competitive, with low but stable gross margins. Tongling Nonferrous is positioned as "primarily a smelter with weak mine self-sufficiency": it has weak bargaining power against upstream miners (directly hurt by TC falling to zero) and only average bargaining power downstream, selling via long-term contracts plus processing margin pass-through—copper prices surged in 2025 while the company "grew revenue without growing profit," precisely reflecting the mine end extracting value from the smelting segment. There is only one path to improvement: raising mine self-sufficiency (Mirador).

Supply-Demand and Competitive Landscape: On the demand side, electrification plus AI provide long-term support; on the supply side, the mine end faces a triple constraint of declining ore grades (global average grade down roughly 40% since 1991, per BHP), insufficient capex (only about 14 major discoveries in the past decade; new projects typically exceed USD 5 billion with 15+ year cycles), and the IEA judges a 30% gap by 2035 on the existing pipeline; meanwhile, Chinese smelting capacity is at an investment peak and clearly in surplus, creating a structural mismatch of "loose refined copper, tight copper concentrate"—on ICSG's basis, refined copper will show a small surplus of 96,000 tonnes in 2026 (less than 0.4% of consumption) and 377,000 tonnes in 2027. The industry is "de-involuting": CSPT member companies will voluntarily cut smelting operating rates by more than 10% in 2026 (involving over 900,000 tonnes of capacity), and the MIIT's Implementation Plan for High-Quality Development of the Copper Industry (2025–2027) strictly controls disorderly smelting capacity expansion and promotes M&A and consolidation. China's smelting CR5 (Jiangxi Copper, Tongling, Chinalco Copper, Jinchuan, Zijin) is approximately 58%. Substitution risk is moderate: aluminum-for-copper (cables/transformers) and recycled copper supply will persist over the long term.

Cycles and Regulation: Historical copper price cycle template—the 2003–2016 supercycle (starting from USD 1,500–2,000, crashing to about USD 2,800 in the 2008 financial crisis, peaking at USD 10,190 in February 2011, bottoming at USD 4,318 in January 2016, with amplitudes of 50–70%); the 2016–2020 mid-cycle (around USD 7,000 in 2018, COVID bottom of USD 4,617 in March 2020); the 2020–2026 cycle (USD 10,845 in March 2022 → USD 11,104 in May 2024 → all-time high of USD 14,527.5 on January 29, 2026). Typical patterns are 2–5 years up and 3–5 years down. Currently (August 2026), LME at about USD 14,200 is in the highest range in history (~100th percentile), only 2–3% below the January peak—historically prices have never held this level for more than a quarter—but what distinguishes this round from prior ones is structural supply constraints and the electrification demand narrative, and institutions diverge widely on the mid-cycle level (Goldman Sachs: 2026 average of USD 12,650 with an expected pullback vs. Guoxin's assumption of RMB 105,000/tonne through 2028). Leading indicators: ① Spot TC/RC (depth of negativity = degree of mine-end tightness; the most critical); ② Inventories across LME/SHFE/COMEX; ③ Refined-vs-scrap copper price spread; ④ SHFE term structure (currently in backwardation with near-month premium; tight physical market); ⑤ ICSG quarterly balance tables; ⑥ CSPT production-cut execution rate. Regulatory direction is broadly positive for the mine end and leading integrated players, negative for small smelters without mines: capacity controls plus voluntary production cuts accelerate smelting consolidation and improve TC/RC expectations; the national resource security strategy encourages overseas expansion (Mirador being the benchmark of Chinese enterprises' first large-scale metal mine in Ecuador).

Company's Industry Positioning: A chaser transitioning toward resource integration. Cathode copper output of 1.9548 million tonnes ranks second in China (Jiangxi Copper first at 2.38 million tonnes), and mine self-sufficiency of roughly 10.1% is low among leading copper companies (Zijin is a pure mining story, with mined copper of 1.085 million tonnes ranking fourth globally). Sources of moat: ① Ultra-large smelting scale and cost competitiveness (a survivor amid industry consolidation; a beneficiary among leaders under CSPT production cuts); ② Mirador's overseas resource positioning—if Phase II comes onstream, self-mined copper could advance toward 310,000 tonnes/year and self-sufficiency rise to 15–25%, shifting the profit structure from "processing fees + by-products" to "mining-led elasticity," allowing the valuation anchor to partially converge toward resource stocks (China Nonferrous at 16.5x); ③ Comprehensive by-product recovery (sulfuric acid/gold/silver) and high-end copper foil (HVLP breaking the foreign monopoly). Risks: persistent negative TCs, uncertainty over Mirador contract signing, and a pullback in copper prices from highs.

XII. Overall Conclusion and Tracking

Overall Assessment: Neutral (wait and see), confidence 0.55, time horizon 12 months. Tongling Nonferrous is a "cycle amplifier": its 10% self-sufficiency structure means its earnings elasticity is weaker than pure mining stocks (Zijin) yet carries an extra layer of copper price and inventory exposure compared with pure processors; the doubling of earnings in 2026H1 is the combined reading of copper prices at the 100th percentile + historically high by-product prices + impairment clean-up. At the current price of RMB 6.67, the stock trades about 19% above the probability-weighted fair value (roughly RMB 5.61) with no margin of safety, and PB is at the 95th percentile of the past 10 years; yet a bearish view equally lacks certainty—the narrative of rising mid-cycle copper prices is backed by the IEA's supply gap, and the Mirador Phase II signing is a genuine re-rating catalyst. Strategically, neither chase nor short; wait for two types of entry triggers—a valuation reset from a copper price pullback below USD 12,000 (at which point the base-case fair value becomes attractive), or an options-style re-rating after the formal signing of the Phase II Mining Contract (at which point the profit structure shift logic must be re-examined). If the LME quarterly average price holds above USD 13,000 into 2027, this report's mid-cycle assumption will be falsified and must be raised upward.

Risk Disclosure: Copper price pullback from historic highs (every USD -1,000 ≈ net profit attributable to parent of RMB -1.0–1.2 billion, plus triggering a second round of impairment on the RMB 38.5 billion inventory); persistent negative TC/RC compounded by falling sulfuric acid/gold/silver by-product prices, leaving the smelting segment without an earnings hedge; failure to sign the Mirador Phase II contract or Ecuador instability affecting Phase I production; H-share issuance dilution and A/H price spread pressure; refinancing dependence given interest-bearing debt of RMB 34.36 billion and a cash-vs-short-term-debt gap of roughly RMB 12.6 billion; margin and basis risks from derivative notional positions of RMB 33.961 billion (89% of net assets); the psychological impact of the controlling shareholder's RMB 2.14 billion-share notional unlock on 2026-09-14 (actual circulation subject to post-performance-commitment review) and the risk of leveraged unwinding given high margin balances (RMB 3.116 billion, 90th percentile over the past year).

Earnings Forecast (this report's basis, for reconciliation anchor): FY2026 revenue of RMB 245.0–256.0 billion, net profit attributable to parent of RMB 5.2–6.2 billion (H1 already achieved RMB 2.993 billion; H2 based on LME USD 12,000–14,000, with impairment reversals and new provisions offsetting in both directions); FY2027 revenue of RMB 250.0–270.0 billion, net profit attributable to parent of RMB 5.0–6.8 billion (copper price mid-cycle of USD 11,500–12,500 + Phase II contribution of RMB 0.5–1.2 billion if signed and ramping in 2028 + TC recovery). This forecast is significantly below Guoxin's 2027E of RMB 11.08 billion (which assumes copper at RMB 105,000/tonne through 2028), and above the implied extrapolation of the 10tonghuashun 3-analyst 2026E consensus mean of RMB 5.735 billion—this will be used for reconciliation at the next earnings release.
