• Further extension of on-market share buy-back program for 12 months
• Buy-back program to run from 1 December 2025 to 30 November 2026
• Extent, timing, and price of buy-backs subject to market conditions

Mount Gibson Iron Limited ('Mount Gibson' or 'the Company') has announced a further extension of its on-market share buy-back program. The Company had previously extended the buy-back program for 12 months, commencing 1 October 2025 to 30 September 2026. As the Company has not acquired any further shares during this extended period, and nearly two months has passed, the Company is required to issue a further notice to ASIC of the share buy-back program or the program will lapse. The Company has taken steps to do this on the basis that the further extended period will be on the same basis as before but for the period 1 December 2025 to 30 November 2026. The further extended share buy-back program will be conducted in the ordinary course of trading in accordance with the terms specified in the accompanying updated Appendix 3C. The extent to which the Company buys back shares, the timing of any buy-back purchases, and the price at which shares are bought back, are each subject to a range of factors including market conditions. The Company does not expect to be in the market at all times during the balance of the potential buy-back period, and any buy-back will occur at the Company's discretion. There can be no certainty that the Company will buy-back all of the 10% of issued shares available under the extended share buy-back program.
