Panama Ties Any Cobre Panamá Deal to Ending First Quantum's Arbitration

First Quantum Minerals Ltd. (TSX: FM) said on 30 September 2026 that a Ministerial Commission appointed by Panama's government has submitted its studies and an audit report on Cobre Panamá, containing seventeen recommendations. The shares fell 15.3 per cent.

The commission's lead recommendation, quoted in the company's release, is the "formal opening of negotiations with Cobre Panamá / First Quantum to assess the feasibility of a new agreement." The agreement contemplated in the report would resolve the international arbitrations now running between the company and Panama, and would allow an orderly closure of the project at no cost to the Panamanian state. The report also recommends transparent administration of the resource for citizens, fixed funding for the environmental plan out of state revenue, an autonomous institution to govern the asset with professional management, and technical management kept away from political cycles. Termination of the pending arbitrations is listed as a mandatory condition.

Panama's president, José Raúl Mulino, said the same day that he would study the report before deciding, according to wire coverage of his remarks. Nothing has been signed, and the company's release does not claim otherwise.

The recommendation is to talk, and the condition is to drop the claims

Two things in the report point in opposite directions, and the share price reflects the tension between them rather than a resolution of it.

The first is that Panama has, for the first time since the 2023 shutdown, put a formal negotiating track on paper. A government commission telling a president to open talks is further than the file has moved in three years.

The second is the price attached. The commission's framework has the arbitrations ending as a condition of the deal, and the object of the negotiation it describes is an orderly closure rather than a return to commercial mining. Read together, the recommendation is not "reopen the mine." It is "negotiate the terms on which the mine is wound down, and drop the lawsuits first."

First Quantum's own response was measured. The company said it would engage in good faith toward a legal framework for Cobre Panamá that is "fair, transparent, durable, and aligned with Panama's Constitution and laws," and that a new agreement must respect Panama's sovereignty and the government-led process. It said it awaits guidance on next steps. It did not accept, reject or characterise the closure language.

An arbitration claim is a lawsuit a company files against a country

This is the part that decides how much the report costs First Quantum, and it is unfamiliar territory for most people who own copper shares.

When a company invests in a foreign country, it is usually protected by a treaty between that country and the company's home state, or by the contract that governs the investment. If the host government then does something that the treaty forbids, such as expropriating the asset without compensation, the company cannot simply sue in the host country's own courts. Instead the treaty lets it take the government to an international arbitration tribunal: a private panel of arbitrators, sitting outside the country, whose award is enforceable against the state's assets abroad.

First Quantum began such proceedings after Panama's Supreme Court ruled the mine's 2023 concession contract unconstitutional and the government ordered the operation shut. The claims are not a side issue. For a company whose asset has been idle for three years, a live arbitration is the mechanism that converts a political loss into a financial recovery, and it is the only instrument the company holds that Panama cannot unilaterally cancel.

That is why the commission's mandatory condition is the centre of the document. Ending the arbitrations means giving up the enforceable claim in exchange for whatever the negotiated agreement provides. Whether that trade is favourable depends entirely on terms that do not yet exist. The report recommends the condition; it does not say what Panama would pay for it, and the company's release contains no number.

The mine is not idle, and that complicates the closure language

A detail from the company's own reporting sits awkwardly beside the word closure. Cobre Panamá is currently operating, at small scale and under licence from the same government.

In its second-quarter results released 28 July 2026, First Quantum reported that Panama authorised a Processing Program on 7 April 2026, that the first of three milling circuits was commissioned in May, and that stockpile processing began. The company reported producing 3,216 tonnes of copper concentrate in the quarter, processing 2.1 million tonnes of ore at an average head grade of 0.23 per cent copper with 67 per cent recoveries.

According to the same results, the recoverable copper still sitting in the stockpile is roughly 70,000 tonnes, and the company guided to 30,000 to 40,000 tonnes of copper from Panama in 2026, against a group-wide guidance range of 405,000 to 475,000 tonnes. The programme's capital cost was estimated at US$250 million, of which US$60 million had been spent as at 30 June 2026. Employment at the site had risen to about 3,000 people by quarter end.

The same results disclosed an independent environmental audit finding 87.7 per cent overall compliance, with 361 of 370 commitments fulfilled and seven partial compliances, mostly in biodiversity management and restoration.

So the asset being negotiated over is a partly restarted operation with three thousand people at it, not a mothballed pit. That does not contradict the commission's recommendation, and it should not be read as evidence that the government intends a full restart. It does mean the practical distance between "orderly closure" and "continued operation" is smaller today than the words suggest, and that the negotiation has a running facility to argue about rather than a hypothetical one.

Copper rose on the day the shares fell

Separating the company from the commodity is the first test of any single-day move in a producer this size, and here the separation is clean.

Copper traded at US$6.57 a pound on 30 September 2026, up 0.35 per cent on the day, per Trading Economics market data. First Quantum closed at C$38.23 on the Toronto exchange, down C$6.89 or 15.3 per cent from the previous close of C$45.12, on 10,215,257 shares traded on the TSX and 16,236,746 across all Canadian venues, per TMX Money data read after the close on 30 September 2026. These are 15-minute delayed secondary market figures and are not verified against SEDAR+ filings.

The intraday range says more than the closing figure. The stock opened at C$45.67, printed a low of C$28.00 and a high of C$46.10, and finished at C$38.23. A low of C$28.00 is a 38 per cent drawdown from the previous close, and the recovery to C$38.23 means the market's first response to the report was considerably worse than where it settled. The volume-weighted average price for the session was C$39.658, above the close.

Copper rose; First Quantum lost roughly C$5.6 billion of market value, from a previous-close capitalisation of about C$37.6 billion to C$31.89 billion at the close, on 834,206,731 shares outstanding. None of that is a copper story.

The security also trades in Frankfurt under the symbol IZ1, WKN 904604, ISIN CA3359341052, per Deutsche Börse's listing record. The Toronto line carried the volume on the day.

The debt is on its own schedule

Whatever Panama decides, the balance sheet keeps its own calendar, and it is the reason a political headline moves this equity as violently as it does.

First Quantum reported net debt of US$5,407 million at 30 June 2026, up US$123 million in the quarter, driven by US$322 million of capital expenditure and US$199 million of taxes paid. Group sales revenue for the quarter was US$1,522 million and EBITDA was US$400 million. C1 cash cost was US$2.48 a pound excluding Cobre Panamá and US$2.54 a pound including it; all-in sustaining cost was US$4.27 a pound. All figures are from the 28 July 2026 second-quarter release and are stated in US dollars.

Against that, the copper price at US$6.57 a pound is comfortably above the company's all-in sustaining cost, and the operating business outside Panama is profitable. The market value that disappeared on 30 September was not an earnings revision. It was a repricing of the probability, and the eventual terms, of the Panamanian outcome.

Two dates are now fixed. The president has the report and has said he will study it. First Quantum reports third-quarter results on 28 October 2026, and that release is the next scheduled occasion on which the company must describe the arbitrations and Cobre Panamá in its own words rather than in a summary of someone else's document.

What the commission's report does not contain is a number. It sets a condition, not a settlement. Until one side puts a figure beside the word arbitration, everything about the size of this outcome is still being guessed at, including by the people who traded it between C$28.00 and C$46.10 on 30 September 2026.
