Greenbushes underperforms; Tianqi Lithium remains Neutral

Overview

This J.P. Morgan China lithium industry dashboard focuses on the read-through from Greenbushes' weak performance to Tianqi Lithium. The report points out that lithium prices remain strong amid accumulating supply disruptions, and energy storage battery demand data are still resilient; however, Tianqi's core asset Greenbushes has seen lowered production guidance, record-low plant feed grade, lower recovery rates, and more maintenance shutdowns, making the net impact on FY26E earnings recovery more balanced.

Core views

The core view is that rising lithium prices are a tailwind for Tianqi's refining assets, but Greenbushes, as a core asset representing about 26% of Tianqi's effective interest, faces production and cost pressures that will offset part of the earnings elasticity. The report believes the market has overreacted in Tianqi's share price rebound and therefore maintains Neutral. At the same time, renewal and category adjustments for Yichun lepidolite mines could further tighten domestic feedstock supply and are important variables to watch for lithium prices and industry chain profits.

Analysis framework

The report uses a combination of supply disruption, pricing, inventory, downstream apparent consumption, and company-specific asset exposure analysis: it first tracks Greenbushes' quarterly production, grade, cost, and capex guidance, then estimates the impact on Tianqi's attributable offtake volume; at the same time, it uses lithium carbonate futures, spot prices, lithium salt margins, SMM inventory, and downstream battery demand to assess industry conditions.

Methodology notes

• Event transmissionread-through analysis

  Deriving the impact on Tianqi Lithium from IGO's Greenbushes operating data

  Greenbushes is an important core asset for Tianqi, and changes disclosed by IGO in production, grade, cost, and maintenance shutdowns affect Tianqi's FY26E earnings through attributable offtake volume, feedstock costs, and refining spreads.

• Supply-demand-inventorysupply-demand-inventory tracking

  Simultaneously observing supply disruptions, downstream demand, and inventory changes

  The report places IGO production cuts, renewal risks for lepidolite mines in Yichun, Jiangxi, resilient energy storage battery demand, and consecutive inventory builds in SMM lithium carbonate stocks within the same framework to assess the sustainability of lithium price support.

• Marginsconversion spread and feedstock margin analysis

  Assessing processing profits under linked movements in lithium salt prices and feedstock prices

  In a supply-constrained environment, spodumene input prices often rise in tandem with lithium salt prices, so even if lithium carbonate prices rise, the expansion of refining spreads may still be limited.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Tianqi Lithium-A 002466.SZ

  primary covered target

  Strengths

  Has an effective interest in Greenbushes, and higher lithium prices help restore profitability of refining assets.

  Weaknesses

  Attributable offtake volume from Greenbushes may decline, and rising feedstock prices limit the expansion of processing spreads.

  Comparison

  The report mentions that both Tianqi and Ganfeng have rebounded recently, but believes Tianqi's rebound is relatively fully priced given the negative changes at Greenbushes.

  Risks

  Improvements in Greenbushes' systemic issues may not be linear, creating downside risks to FY26E production and profits.

• Tianqi Lithium-H 9696.HK

  H-share covered target of the same company

  Strengths

  Also benefits from elevated lithium prices and industry supply disruptions.

  Weaknesses

  Affected by the same Greenbushes operating drag as the A-shares, while Hong Kong stock liquidity and valuation may differ.

  Comparison

  The report discloses a Tianqi-H price of HK$60.45, with the same Neutral rating.

  Risks

  Lithium price pullback, continued inventory accumulation, or slower-than-expected Greenbushes recovery.

• Greenbushes

  Tianqi's core upstream asset

  Strengths

  A world-class lithium mine asset with major importance to Tianqi's long-term resource endowment.

  Weaknesses

  3Q26 production did not improve despite CGP3 contribution, grade fell to 1.64% Li2O, and cost guidance was raised.

  Comparison

  Compared with the previous 2%+ plant feed grades and higher production guidance, operating performance this period was clearly weak.

  Risks

  Management says the issues are systemic, and improvement is usually not linear.

• Lithium carbonate/lithium salt prices

  Industry earnings and share price driver

  Strengths

  Supported by accumulating supply disruptions and resilient energy storage demand.

  Weaknesses

  Continuous accumulation in SMM inventory shows supply-demand conditions are not one-sidedly tight.

  Comparison

  Both lithium carbonate spot and futures prices remain elevated, with futures still trading at a premium to spot.

  Risks

  If downstream demand weakens or inventories continue rising, price support may fade.

• Ganfeng Lithium-A/H

  comparable company

  Strengths

  Also a core listed company in China's lithium industry chain, benefiting from rising lithium prices.

  Weaknesses

  The report mainly uses it for share price performance and peer observation, without elaborating on changes in company fundamentals or ratings.

  Comparison

  It has risen 6-9% alongside Tianqi recently, but this report focuses on Greenbushes' differentiated impact on Tianqi.

  Risks

  Industry lithium price volatility and inventory changes also affect valuation.

Impact & implications

In terms of investment implications, strong lithium prices are themselves positive for Tianqi, but Greenbushes production cuts, grade declines, and higher cost guidance mean Tianqi's upstream attributable volume and profit elasticity are lower than what the market might simply extrapolate from rising lithium prices. If supply disruptions in Yichun, Jiangxi materialize, lithium prices may continue to receive support; however, inventories have already accumulated consecutively, with trader inventory builds particularly evident, suggesting an ongoing tug-of-war between price increases and fundamental digestion.

Risks

• Greenbushes production, grade, and recovery rates remain below expectations, leading to declines in Tianqi's attributable offtake volume and earnings.
• Feedstock prices such as spodumene rise in tandem with lithium salt prices, compressing refining spreads.
• Domestic lithium carbonate inventories continue to build; if demand cannot absorb inventory, lithium prices may fall back.
• The outcome of lepidolite mine renewals or category adjustments in Yichun is uncertain and may bring either positive or negative supply-side shocks.
• The share price may have already priced in expectations of rising lithium prices in advance; if fundamental recovery is insufficient, valuation faces pullback risk.
• The report discloses that J.P. Morgan has market-making, liquidity provision, shareholding, client, and potential investment banking business relationships with securities related to Tianqi, so conflict-of-interest disclosures should be noted.

What to watch

• IGO's subsequent quarterly updates on Greenbushes production, grade, recovery rates, maintenance shutdowns, and costs.
• Whether Greenbushes FY26 production guidance is adjusted further, especially whether the 1,375-1,425kt range can be achieved.
• Whether the four lepidolite mines in Yichun, Jiangxi suspend production from May and undergo mineral category adjustments.
• Whether Jianxiawo resumes production, and its impact on the tightness of domestic feedstock supply.
• Whether SMM lithium carbonate inventory continues to build, especially the divergence between trader inventories and downstream battery and cathode material inventories.
• Changes in the spread between lithium carbonate futures and spot, spodumene prices, and lithium salt processing spreads.
• Whether energy storage battery demand data can continue to support elevated lithium prices.
