Key Highlights

  • A final Investment decision was taken on the P2000 expansion at Pilgangoora, with about A$1.9 billion committed.
  • Spodumene concentrate production was a record 267.6 thousand tonnes, up 25% on the June quarter.
  • The realised price fell 14% to US$1,809 per tonne, while sales fell 11% to 223.6 thousand tonnes.
  • Sales were partly delayed by a 15 thousand tonne shipment that slipped into October following delays at Port Hedland.

Why would a lithium producer commit about A$1.9 billion to expansion in a market where its own realised price fell in the latest quarter? PLS Group (ASX:PLS) did exactly that on 16 October 2026, when it took a final investment decision on the P2000 expansion of its Pilgangoora operation in Western Australia. The Quarterly Report released on 28 October 2026 shows the context: record production, a lower realised price, falling Revenue and a large cash balance. The decision is a bet on lithium Demand over the medium term, funded by a Balance Sheet that gives the company room to act while competitors hold back. The period-specific figures provide context for the company’s operating performance and execution priorities.

The September 2026 quarter

According to PLS's quarterly activities report as summarised from the ASX filing, spodumene concentrate production was a record 267.6 thousand tonnes, up 25% from 214.3 thousand tonnes in the June quarter. Sales were 223.6 thousand tonnes, down 11% from 249.9 thousand tonnes, partly because a 15 thousand tonne shipment slipped into October following delays at Port Hedland.

The realised price was US$1,809 per tonne on a CIF China basis at about 5.2% lithium oxide content, or US$2,077 per tonne on a 6% lithium oxide basis. Both were down 14% on the previous quarter. The price was US$1,754 per tonne as at 26 October. Revenue was A$563 million, down 24%, and included a provisional pricing adjustment of negative A$69 million at 30 September, estimated at negative A$88 million by 26 October.

The company expects costs to rise over the rest of FY27 because of wet-season effects and other pressures. The cash balance was A$2,217 million at 30 September, down from A$2,290 million, after a A$161 million final FY26 Dividend and A$42 million spent on tenements near Colina. Net cash was A$1,277 million and total Liquidity A$2,717 million. On 26 October the company also completed an issue of US$700 million of 8% senior notes due 2032.

The P2000 expansion

P2000 lifts Pilgangoora's capacity to about two million tonnes per year of spodumene concentrate. The company reported a final investment decision of about A$1.9 billion, with first production expected in the September quarter of calendar 2029. Feasibility study outputs show an incremental post-tax net present value of A$2.7 billion at an 8% real discount rate and a post-tax internal rate of return of 29.5%, based on a long-term price assumption of US$1,620 per tonne on a 6% lithium oxide basis. A power purchase agreement with Fortescue, signed on 28 October, is expected to reduce P2000 unit costs by about A$15 to A$20 per tonne.

These are company projections, and the returns depend heavily on the long-term price assumption. The current realised price of US$1,809 per tonne is above that assumption, but spodumene prices have been very volatile, and a project completed in 2029 will be exposed to the price at that time. The investment also raises the Capital commitments: FY27 Capital Expenditure guidance was revised to A$1,130 million to A$1,195 million, including A$500 million for P2000 growth and A$185 million for infrastructure such as the access road, village, mine services Facility and power agreement.

FY27 guidance and other projects

The Ngungaju plant restarted in July as planned, performed in line with expectations and reached full operational status by the end of October. At the Colina project in Brazil, the feasibility study remains on schedule for the December quarter of 2027, and the company has begun infill resource drilling on newly acquired tenure. A mid-stream demonstration plant is expected to produce its first lithium phosphate product in the December quarter of 2026.

PLS also holds an 18% interest in a joint venture with POSCO in South Korea, which operates a lithium hydroxide plant at Gwangyang. In the quarter it ran on a moderated single-train basis, producing 3,520 tonnes of lithium hydroxide, of which 98% met battery-grade specification, and selling 3,376 tonnes to customers in Europe, Korea, Japan and China. PLS has a Call Option to increase its interest to 30% and a Put Option in certain circumstances.

Business model and competitive position

PLS mines and processes hard-rock lithium, selling spodumene concentrate to converters, mainly in China, who turn it into chemicals for batteries. Its revenue depends on Volume sold, the spodumene price and dollar. Pilgangoora is among the world's larger hard-rock lithium resources, which gives it scale and, as the quarter's cost figure shows, relatively low unit costs.

Risks

Lithium price Volatility and the uncertain long-term price assumption behind P2000.

Cost pressure, including wet-season effects and inflation, with costs expected to rise.

Execution risk on a large expansion, including budget and schedule.

Provisional pricing exposure, which can reduce reported revenue after quarter end.

Policy and demand risk for electric vehicles and energy storage.

What to watch

The December quarter should show whether the shipment that slipped is sold, how the price has moved and whether costs rise as guided. Other dated milestones include the first lithium phosphate product from the demonstration plant in the December quarter of 2026, the Colina feasibility study in the December quarter of 2027 and the first P2000 production in the September quarter of calendar 2029.

PLS is investing through a weak price period from an encouraging financial position. Whether that proves wise will depend on lithium demand in 2029 and beyond, which no one can know.
