SHERRITT ANNOUNCES THE RETIREMENT OF ITS CHAIRMAN

Sir Richard Lapthorne, chairman of Sherritt International Corp.'s board of directors, has advised the corporation that his previously announced retirement will be effective today due to personal reasons.

Mr. Lapthorne has served as chairman of the board since June, 2019. Over that time, the corporation has undergone significant transformation, strengthening its balance sheet, advancing operational capabilities and navigating an extended period of commodity price volatility.

"Serving as chairman of Sherritt has been a profound responsibility and privilege," said Mr. Lapthorne. "With the corporation now well positioned for long-term growth, this is the right time to begin a leadership transition. I have every confidence in the board and executive team to continue building on the momentum we have established."

During Mr. Lapthorne's tenure as chairman, Sherritt completed two major debt restructurings, implemented a disciplined capital strategy and made critical investments to extend the life of key operations. These efforts have enabled the corporation to deliver improved future cash flow, enhance operational efficiency and position itself as a reliable supplier of critical minerals.

"On behalf of the corporation, I want to thank Sir Richard for his leadership," said Leon Binedell, president and chief executive officer of Sherritt. "His guidance helped steer Sherritt through market turbulence and into a position of great potential. We are deeply grateful for his service."
