Further progress on plans to produce Copper, Platinum Group Metals ("PGMs"), Nickel and Cobalt as By-products

• On April 10, 2026, Largo filed a request before the Brazilian Mining Agency ("ANM") to produce and sell copper, platinum group metals, nickel and cobalt as by-products within its existing mining activities at the Maracás Menchen Mine and using its existing ore processing infrastructure.

• The latest assays received from flotation concentrate tests using part of Largo's ilmenite flotation plant continued to yield positive results. Concentrates analyzed externally at a certified laboratory yielded 16.6% copper, 13.4 grams per tonne ("gpt") gold, 22.5 gpt platinum, 22.4 gpt palladium, 69 gpt silver, 0.8% nickel, 0.8% cobalt, and 0.1 gpt rhodium. This new data is the average of the second period of four days of continuous industrial-scale testing using current mine feed from the Maracás Menchen mine. The results of the first four-day test period were reported in the April 1, 2026 Press Release.

Update on Senior Leadership Structure

• Mr. Luis Rendón now serves as sole Chief Operating Officer and Mr. Luânder Peixoto was promoted to serve as Group General Counsel.

Toronto, Ontario--(Newsfile Corp. - April 14, 2026) - Largo Inc. (TSX: LGO) (NASDAQ: LGO) ("Largo" or the "Company"), the world's largest primary vanadium producer, today announces production of 2,616 tonnes of V₂O₅ equivalent from its Maracás Menchen Mine and sales of 2,141 tonnes of V₂O₅ equivalent in the first quarter of 2026. The Company also announced that on April 10, 2026, it filed a request before the ANM to produce and sell copper, PGMs, nickel and cobalt as by-products in its existing mining activities at the Maracás Menchen Mine. Largo also announced that Mr. Luis Rendón now serves as sole Chief Operating Officer and Mr. Luânder Peixoto was promoted to serve as Group General Counsel. Largo wishes to thank Mr. Gordon Babcock for his service as Co-Chief Operating Officer who assisted with implementing operational improvements at the Maracás Menchen Mine.

Mr. Daniel Tellechea, Co-Chief Executive Officer of Largo, commented: "First quarter 2026 production was at the upper end of our guidance range, reflecting continued operating improvements at the Maracás Menchen Mine and the progress made under our operational turnaround initiatives. Improved open pit mine access, higher grade ore availability and more consistent ore processing and chemical plant performance resulted in doubling our vanadium pentoxide production volume in the first quarter versus last year and reinforces our confidence in the operational outlook for the remainder of 2026."

Mr. Alberto Arias, Co-Chief Executive Officer of Largo, added: "The operating results of the first quarter of 2026 reflect a stronger operating base for Largo. We remain focused on translating that production performance into stronger sales, leveraging the recent positive commercial momentum in the vanadium market. Vanadium prices in the U.S. have increased materially year to date and, together with the reduction in U.S. tariff barriers on Brazilian products, have enhanced Largo's ability to actively supply both the high purity market, particularly the aerospace industry, as well as the U.S. ferrovanadium market, where the number of origins able to serve customers remains limited. Against that backdrop, we are focused on increasing high purity vanadium volumes and expanding sales tonnage in the U.S. ferrovanadium markets."

With respect to the outlook for Q2 2026, Mr. Arias stated: "It is important to note that there is a lag in price realization on Largo's reported sales, so an important portion of the recent price increase should be reflected in Q2 2026 sales revenues. In addition, most of the sales of the high-purity inventories accumulated in bonded warehouses in Baltimore as a result of the 50% U.S. tariffs will also be reflected in the second quarter, as invoicing of those sales took place in April 2026 following the U.S. tariff reduction in the middle of the first quarter. As a result, higher pricing momentum in the market should support stronger revenue realization in the second quarter than would have been the case had those units been sold in the first quarter."

Maracás Menchen Mine Operational and Sales Results

ANM Request to Produce and Sell Copper, PGMs, Nickel and Cobalt

The request filed on April 10, 2026 before ANM follows the Company's previously disclosed metallurgical testing and technical evaluation of copper, PGMs, nickel and cobalt-bearing material using part of its existing flotation plant circuits.

Any inclusion of these minerals in the Company's mining activities remains subject to the outcome of the applicable regulatory process in Brazil, as well as any additional technical, environmental and operational assessments that may be required.

As announced on April 1, 2026, externally analyzed concentrate results from four days of continuous industrial-scale testing using current mine feed from the Maracás Menchen Mine yielded 17% copper, 14.3 grams per tonne gold, 16.2 grams per tonne platinum, 13.2 grams per tonne palladium, 69 grams per tonne silver, 0.8% nickel and 0.7% cobalt.

The latest assays results from a second four-day test period using part of Largo's ilmenite flotation plant analyzed externally at a certified laboratory yielded 16.6% copper, 13.4 grams per tonne gold, 22.5 grams per tonne platinum, 22.4 grams per tonne palladium, 69 grams per tonne silver, 0.8% nickel and 0.8% cobalt and 0.1 grams per tonne rhodium.

Mr. Tellechea stated: "The ANM filing marks an important step in advancing Largo's evaluation of copper, PGMs, nickel and cobalt as by-products of our existing operations. It reflects the progress of our technical work to date and supports our broader objective of optimizing the value of our mineral endowment and processing infrastructure over time. As we continue our technical and economic evaluations, this regulatory step helps position the Company to advance the inclusion of copper, PGMs, nickel and cobalt within its mining activities, subject to the applicable review and approval process."

Mr. Arias added: "We believe this filing demonstrates the confidence of our operating team in our ability to produce these critical minerals as a by-product of our existing vanadium mining-processing operations. Producing and selling these concentrates will allow us to potentially generate revenue while we review cost and revenue data for this project. This information is essential to quantify in real-time the benefits of using a portion of our ilmenite flotation infrastructure to produce these copper-PGMs concentrates. This project is part of our strategy to enhance the long-term competitiveness of our vanadium mining operations with by-product credits from Largo mined materials, stockpiles and tailings, as well as to diversify revenues with the addition of copper, gold, platinum, palladium, cobalt and nickel. The recent results showing 0.1 grams per tonne of rhodium in the copper-PGMs concentrates are encouraging, given the high value of rhodium and its unusual occurrence even in well-known PGMs deposits."
