Exhibit 99.1

ASX Announcement

28 October 2025

Financial support transaction

Coronado Global Resources Inc. (ASX: CRN) (“Coronado”) announces today that it proposes to enter into a transaction with Stanwell Corporation Ltd (“Stanwell”) that will improve Coronado’s short- and long-term financial viability.

This arrangement will also support local jobs, secure over 10% of Queensland’s energy needs, encourage more investment into Australian coal and will provide greater employment certainty for 2,500 people and their families in Central Queensland.

The transaction, which is currently non-binding and subject to completion of due diligence, long-form documents and approvals during November, will provide near- and long-term liquidity support for Coronado. The existing New Coal Supply Agreement (“NCSA”) will remain in place and the end date will be extended from 2037 to 2043 and allow Stanwell a wider, more flexible, nomination range of 1.2 to 2.24 million tonnes per year.

The current asset-based loan in place with Highland Park XII Pte. Ltd (an affiliate of Oaktree Capital Management, L.P.) will be replaced by Stanwell. A US$265M, 5 year facility, with an interest rate between 9 to 12% that provides significant covenant flexibility will be available at closing. Stanwell will have a first priority security over Coronado’s working capital assets and a second priority security over all other fixed assets for the asset-based loan, and retain its lower ranking security over all assets for Coronado's NCSA obligations. From the beginning of 2026, Stanwell will waive the rebate payments for the remaining term of the Amended Coal Supply Agreement (“ACSA”).

Ongoing financial support to Coronado, when required, will consist of Stanwell making prepayments for future NCSA coal to a maximum of the discounts that Stanwell would have received under the ACSA and NCSA nominations. This will only be provided in months when Coronado’s cash balance is below US$250M. The prepayments will bear a competitive fixed interest rate, the capitalisation of which is capped.

In months when Coronado’s cash balance is above US$300M, Coronado will deliver nominated NCSA tonnes that have been prepaid for by Stanwell at no cost and thereby reduce the prepayment balance.

If dividends are declared, Coronado will be required to maintain liquidity of at least US$300 million after such dividend payments, any required repurchases of its senior notes and an equal or higher reduction of amounts that have been prepaid by Stanwell, depending on the prepayment balance. This will cause appropriate de-leveraging of Coronado’s balance sheet for a cyclical commodity business.

This announcement was authorised for release in accordance with the Disclosure Policy of Coronado Global Resources Inc.
