Largo Inc. ("Largo" or the "Company") (TSX:LGO) (NASDAQ:LGO), one of the world's largest primary vanadium producers, is pleased to announce the appointment of J. Alberto Arias and Daniel Tellechea as its co-Chief Executive Officers effective immediately and the transition of Mr. Arias to Executive Chairman effective immediately. Mr. David Brace will act as Lead Director.

Largo also announced that Mr. Diogo Silva, who has been with the Company for the past fourteen (14) years, will be appointed Chief Financial Officer, effective December 5, 2025. Mr. Silva will succeed David Harris, who after more than 10 years with Largo, will step down as CFO effective December 5, 2025.

Mr. Arias and Mr. Tellechea will manage the Company through the next phase of operations with their complementary skill sets and focus on the execution of Largo's strategy to continue to reduce costs, diversify revenues and work to refinance its debt.

Mr. Arias commented "I look forward to contributing to Largo my over 30 years of experience, which has been focused on the investing, financial, and operational aspects of the industry. Largo plays a critical role in the supply chain of vanadium for the U.S. and Western Nations since approximately 80% of world's vanadium supply is produced in China and Russia." Mr. Arias added, "Daniel Tellechea has done a remarkable job reducing operating costs to adapt to an extended period of low vanadium prices and the more recent effects of large U.S. tariffs and liquidity constraints. I am excited to work together with Daniel with his invaluable experience in managing mining assets under challenging market conditions."

J. Alberto Arias, through the investment funds he manages, has been invested in the Company since 2010 prior to the mine's construction. Mr. Arias joined the Largo Board in 2011, and has been Largo's Non-Executive Chairman since 2019. Mr. Arias is the founder and portfolio manager of Arias Resource Capital Management, and director of the General Partner to funds managed by Arias Resource Capital that are the Company's largest shareholder. Collectively, shares held by funds managed by Arias Resource Capital and Mr. Arias represent approximately 37.9% of the basic shares outstanding of the Company after the recent financing completed October 22, 2025.

Largo would like to thank Mr. Harris for his valuable contributions to Largo over the past decade at Largo. Mr. Silva is currently the Finance Director of the Company's subsidiary, Largo Vanádio de Maracás S.A. ("LVMSA") and has been instrumental in the Company's negotiations with its lenders to defer debt principal payments until September 2026.
