On March 22, 2023, the Company entered into an Unsecured Credit Facility Agreement, which was amended on July 31, 2023 (“2023 Credit Facility”), with Argentum Cedit Virtuti GCV (the “Lender”), the parent of Allseas Investments S.A. (“Allseas Investments”) and an affiliate of Allseas, pursuant to which, the Company could borrow from the Lender up to $25 million in the aggregate, from time to time, subject to certain conditions. All amounts drawn under the 2023 Credit Facility bore interest based on the 6-month Secured Overnight Financing Rate, 180-day average plus a margin of 4.0% per annum payable in cash semi-annually (or plus a margin of 5% if paid-in-kind at maturity, at the Company’s election) on the first business day of each of June and January. The Company had to pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remained undrawn under the 2023 Credit Facility. The Company had the ability to settle certain charges under the 2023 Credit Facility in cash or in equity at the discretion of the Company. The 2023 Credit Facility also contained customary events of default. On March 24, 2025, the Company entered into a Letter Agreement with the Lender, pursuant to which the 2023 Credit Facility was cancelled with the only obligation remaining being the underutilization fees amounting to $2 million.

As at March 31, 2026, the total amount payable to Allseas and its affiliates was $34.1 million of which $32.1 million related to the development of the nodule collection system and $2 million related to the underutilization fees payable on the 2023 Credit facility.

These amounts were recorded in accrued liabilities in the consolidated balance sheet which can be settled in cash or equity at the Company’s discretion (Note 11) (December 31, 2025: $34.2 million, recorded as accrued liabilities). As at March 31, 2026, Allseas and its affiliates owned 56.1 million common shares of the Company (2025: 56.1 million TMC common shares) which constituted 13.0% (December 31, 2025: 13.3%) of total common shares outstanding.

Subsequent to March 31, 2026, the Company entered into a Contract for Development Work and Commercial Production with Allseas Deepsea Marine Contractors, a wholly owned subsidiary of Allseas, as further described in Note 19.
