Adjusted EBITDA for the third quarter of 2026 was $358 million, which the company described as a record. Revenue rose 19% compared with the same quarter of the previous year, showing growth in both the top line and the earnings measure.

Because the figures are presented on a 100% basis, they include the full output of the operations in which Capstone holds an interest. Readers comparing the quarter with the company's reported share should refer to the attribution details in the full release.

Mantoverde and Portfolio Changes

The company completed the sulphide concentrator tie-in for its Mantoverde Optimized Project during the quarter. The tie-in connects new processing capacity into the existing operation, and the company describes it as a key project milestone.

Capstone also entered into a definitive agreement to divest its Cozamin operation. The company said the sale will optimise its portfolio and further strengthen its balance sheet. In a separate step, it continued to consolidate the Mantoverde-Santo Domingo district through the acquisition of San Pietro.

Strategic Direction

The release presents the Mantoverde and San Pietro steps as part of a plan to build out the district around Mantoverde. The company's chief executive described the quarter as one of significant progress, a description the release uses for the company's own activities.

The divestment and acquisition are described in the release as separate transactions, and the financial terms of each are reported only in summary. Readers will need the full filings to measure the effect on the balance sheet.

Final Word

Capstone's third-quarter 2026 results combine record adjusted EBITDA and 19% revenue growth with progress on the Mantoverde Optimized Project and a reshaping of the portfolio through the planned sale of Cozamin. The San Pietro acquisition adds to the company's holdings in the Mantoverde-Santo Domingo district. Subsequent reports will show how these changes are reflected in production and revenue.
