Ur-Energy Announces Retirement of CEO John Cash, Names President Matthew Gili as Successor

LITTLETON, CO / ACCESS Newswire / October 13, 2025 / Ur-Energy Inc. (NYSE American:URG)(TSX:URE) ("Ur-Energy" or the "Company") today announced, as part of the Company's long-term leadership succession planning, that John W. Cash, who has been with Ur-Energy since 2007 and has served as Chief Executive Officer (CEO) since 2022, will resign as CEO on December 12, 2025. Matthew D. Gili, the Company's President, will succeed Mr. Cash as CEO and will also join the Board of Directors on December 13, 2025. Mr. Cash will continue to serve as Chairman of the Board of Directors. He will also continue working closely with the management team as a strategic advisor following his retirement to support a seamless leadership transition and ongoing Company growth.

During his time as CEO of Ur-Energy, Mr. Cash has been instrumental in securing a robust contract book of uranium sales agreements which facilitated the Company's 2022 decision to return to commercial production at the Company's Lost Creek project and the 2024 decision to construct the Company's second in situ recovery project, Shirley Basin, which is expected to commence operations in early 2026. Previously, Mr. Cash led the permitting and licensure of the Lost Creek Mine, which ultimately became a leading low-cost uranium producer, its expansion into LC East and the Shirley Basin Mine.

Mr. Cash stated, "After 18 years with Ur-Energy and 31 years in the uranium exploration and mining industry, it is time for me to retire from day-to-day management. Ur-Energy's strong executive team and Board have been an absolute pleasure to work with over the past nearly two decades. The Company is well-positioned for significant growth, and I look forward to utilizing my years of experience in the industry while continuing as Ur-Energy's Chairman of the Board and as an engaged strategic advisor."

Mr. Cash continued, "Over the past several months, Matt Gili has demonstrated his skills in leading safe operations, and I am confident that Matt and his highly experienced management team will lead the Company into its best days as we all enjoy the burgeoning nuclear renaissance."

He added, "I don't plan on leaving the nuclear industry. I will be forming a non-profit with the objective of exposing young adults to opportunities in science and the nuclear industry. For the nuclear industry to respond to growing demand and realize its full potential, we must attract and retain a qualified workforce across the entire fuel cycle. As a long-time participant and beneficiary of the nuclear industry, I feel it is incumbent on me to be a part of that effort."
