Retirement of Non-Executive Director

Comet Ridge Limited (ASX:COI) (Comet or the Company) wishes to advise the retirement of Mr Shaun Scott from his role as Non-Executive Director with effect from today.

Mr Scott joined the Board in October 2019 and was appointed Chair of the Remuneration Committee and a member of the Audit Committee in November 2019 and later was appointed Chair of the Audit Committee in November 2025. Mr Scott is retiring from the Board due to recent personal and business commitments which no longer allow him to dedicate the necessary time and focus on the role.

On Mr Scott's retirement, Chairman James McKay said, "On behalf of the Board, I would like to thank Shaun for his substantial contribution to Comet Ridge over the past seven years. Shaun's extensive resources industry experience, having been the CEO of Arrow Energy, has been a significant asset to the Board with his expertise in business strategy, negotiations, financial and risk management. I know I speak for my fellow directors when I say we have thoroughly enjoyed working with Shaun. I wish him all the very best for the future."

About Comet Ridge

Comet Ridge Limited (ASX: COI) is a publicly listed Australian energy company focused on the development of natural gas resources for the strained east coast Australian market. The company has tenement interests and a suite of prospective projects in Queensland. Our flagship Mahalo Gas Hub project consists of low cost, sales spec natural gas blocks, close to Gladstone, containing low $\mathrm{CO}_{2}$ Gas Reserves. Our exploration assets offer further upside amid increasing domestic and international demand for natural gas as a source for cleaner energy and as a key manufacturing feedstock that makes thousands of products, used daily.

Comet Ridge plans to transition its Mahalo Gas Hub assets into meaningful gas supply into the east coast gas market, commencing with Mahalo North and the larger Mahalo Gas Project, in joint venture with Santos QNT Pty Ltd (as the Development Operator). These projects will be further supplemented by planned development of gas resources from Comet Ridge's other $100\%$ held permits, Mahalo East, Mahalo Far East and the newly awarded Mahalo Far East Extension.
