Tharisa's +85% PGM basket rewrites the model — and the cash is already funding a strategic pivot
H1 FY2026 EBITDA +138%, EPS +532%, a now-fundable underground build, Zimbabwe fiscal stability in reach, and a U.S. ADR: the co-producer is converting a price windfall into growth capital.
THA.JO · Earnings Call · 2026-05-25
The headline number hides the real move
Tharisa's interim result for the six months to 31 March 2026 is not a routine beat. Revenue rose 28% to $359.4 million and EBITDA jumped 138.1% to $104.3 million, but the figure that rewrites the model is the PGM basket, which averaged $2,599 per ounce — up 85.3% from the comparable period — while PGMs themselves were flat in volume terms and chrome only mildly firmer. The earnings flow-through is enormous: EPS hit $0.158, up 532%, and the Board raised the interim dividend to $0.025 per share (a 15.9% payout). CFO Michael Jones was uncharacteristically direct about where the credit belongs: “the star performer, the PGM prices making a significant contribution to our increase in EBITDA” — Michael Jones, Chief Financial Officer (CFO) · 2026-05-25.
The co-product math and an unusual prill split
The reason the basket move lands so hard on the P&L is Tharisa's co-production model, running a prill split that is unusually rhodium-heavy — rhodium is roughly 10% of production but, as Jones showed, contributes about 35% of revenue on the back of very strong prices. That skew compresses costs when management recasts the business as a pure PGM producer:
we then say we're an all-in cost producer of only platinum to compare to some of our peers, we get a negative cost of $2,822.
Read with the all-in sustaining cost of $268 per ounce (before Karo) against a basket near $2,800, the margin geometry is striking — and management is confident it persists. Phoevos Pouroulis argues the deficit narrative is structural: “we're still forecasting deficits across all 5 key elements, rhodium, platinum, palladium, ruthenium and uridium” — Phoevos Pouroulis, Chief Executive Officer (CEO) · 2026-05-25, with new demand vectors — AI data centers, high-speed processing, e-glass — layered on top of a slower-than-expected transition away from internal combustion engines.
The genuine risk: fuel, freight, and the Middle East
For all the upside, the call is punctuated by a real cost and supply threat that aligns Tharisa with a global theme. Diesel constitutes 10.9% of all-in on-mine costs, and the transcript repeatedly circles back to the Gulf conflict. On supply security, Pouroulis is measured: “as the war broke out, our #1 risk was security of supply” — Phoevos Pouroulis, Chief Executive Officer (CEO) · 2026-05-25 — mitigated with a Tier-1 oil trader, secondary and tertiary suppliers, and added bunkering — while the stated goal of a ~10% reduction in fuel per cubic metre moved is a concrete consumption lever. The freight costs story is the other side of the same coin: chrome's inland logistics and freight rose 6.8% to $86.5 per tonne, and management notes the chrome price has already adjusted to compensate for the freight spike. Export routing is being rebalanced toward rail (22% of cargoes this half, up from almost nothing), with Maputo handling 60% of volumes.
Capital deployment: funding Karo, the underground, and a U.S. listing
The strategic content of this report, though, is in how the windfall is being spent. Peak funding for the Underground development has been cut by $45 million on the back of stronger prices, and the full $179 million in facilities is now secured. On Karo Platinum — $241 million invested to date, roughly 15 months from first ore in mill — the gating item has always been fiscal certainty, and Pouroulis reports the negotiation is effectively settled: “we have agreement and alignment with the government who are our partners in the project with a 15% interest” — Phoevos Pouroulis, Chief Executive Officer (CEO) · 2026-05-25, with the focus now on the fiscal stability provisions that lenders require around ForEx convertibility. A DFI-backed, shorter-dated funding package is said to be well advanced.
Simultaneously, the company is courting a broader shareholder base — a Level 1 ADR with JPMorgan (live from 8 June), and explicit optionality to migrate to an LSE premium listing to capture "heightened interest from the U.S. and European strategic investors" around critical minerals. Less conventional, and the most company-unique thread, is the commercialization push through Arxo Metals: the Flow battery — an iron-chromium redox system using Tharisa's own chrome to make electrolyte — has passed factory acceptance testing on a megawatt-class unit, with Tharisa's own mine as first customer and a second unit headed to Europe.
Why it matters
Strip away the commodity surge and Tharisa is quietly executing a three-part transformation: self-funding a 60-year underground life extension, de-risking the Zimbabwe growth engine, and building a technology/hydromet vertical that monetizes its own ore. The countercyclical chrome-PGM pairing, which management credits for resilience through weak PGM years, now has both legs of the pair working at once — and the board has shown it will return capital even mid-build. The risk is symmetrical: a diesel shock or a stalled Karo sign-off would dent the narrative quickly, and the valuation discount the company highlights on EV/EBITDA versus FTSE 250 peers reflects that. But after this half, the story is no longer about price alone — it is about what the price has paid for.
