Unasserted legal claim

The Company uses third-party labor providers to support certain operations. In connection with this model, there is an unasserted, labor-related contingency that could, under certain circumstances, give rise to secondary exposure for the Company if the applicable contractor were unable to satisfy any settlement or judgment. As of the reporting date, no claims have been filed or asserted directly against the Company, and the contractor has not indicated any unwillingness or inability to meet its legal obligations. The contractor remains the primary obligor with respect to any such obligations, and any potential exposure to the Company, if ultimately incurred, would be secondary to the contractor’s primary responsibility.

Based on management’s assessment of the information currently available, the Company determined that a loss related to this matter is probable and reasonably estimable. The Company's balance sheets as of June 30, 2026 and December 31, 2025, include other non-current liabilities of $62 and $47, respectively, for this matter.

The Company will continue to monitor developments and update its estimates as additional information becomes available.

Exercise of Mining Rights Option

On June 30, 2026, the Company, through its subsidiary AMBPL, delivered notice of intent to exercise its option to acquire certain mining concessions, exploration permits, and an exploration application held by the GMC Grantors in Brazil (“GMC Option”), as more fully described in the Prospectus. Under the terms of the GMC Option, the aggregate exercise price of approximately US$5.16 million is payable through the issuance of 271,579 REA Shares, based on the $19.00 per share offering price. The Company has not issued the shares required to settle the exercise price, pending execution of a definitive subscription agreement with the GMC Grantors.
