Argan, Inc. (NYSE: AGX) ("Argan" or the "Company") announces today that Rainer H. Bosselmann, Founder, Chairman and Chief Executive Officer retired effective August 16, 2022. The Board of Directors of Argan (the "Board") has appointed David H. Watson to succeed Mr. Bosselmann as President and Chief Executive Officer ("CEO") and Mr. Watson will also join the Board.

"On behalf of the Board, the management team, and Argan's employees, we want to thank Rainer for his leadership and significant, positive impact over almost two decades with the organization," said James Quinn, Argan's lead independent board member. "A steadfast and conservative leader, Rainer founded Argan in 2003 and fostered the management team that is in place today. During his tenure, he played a significant role in transforming the Company from a small, $30 million company to an international business with annual revenues and a market cap that exceed $500 million today. He built up the balance sheet, focused on margins, empowered employees throughout the organization and returned to shareholders approximately $175 million in dividends and $75 million in share repurchases. In addition, Rainer was instrumental in the evolution of Argan with the transformative acquisition of Gemma Power Systems in 2006. The Board is sincerely grateful to Rainer for his dedication to Argan and positive impact on shareholder value. We are all thankful that he has agreed to continue serving as a member of the Board."

"David has worked closely with me as Chief Financial Officer ("CFO") of Argan for almost seven years and the transition should be seamless," said Mr. Bosselmann. "He has a deep understanding of our businesses, good rapport with investors and a strong track record of leadership and execution."

"I want to thank Rainer and the Board for their confidence in me as I step into this role," said Mr. Watson. "These are big shoes to fill and I pledge to work tirelessly with all of our employees to build on past successes and to lead the Company into its future."

With Mr. Watson taking on the President and CEO position, long time Corporate Controller, Richard H. Deily, will step into the CFO position. Mr. Deily joined the Company in October 2007 and has worked closely with Mr. Watson and Mr. Bosselmann over the years. Additionally, current Board member William F. Leimkuhler has been appointed Chairman of the Board.
