Q2 2024 and Other Highlights

• V₂O₅ production of 2,689 tonnes (5.9 million lbs¹) in Q2 2024 vs. 2,639 tonnes produced in Q2 2023 and 56% above production of 1,729 tonnes in Q1 2024; Within the Company’s quarterly production guidance range of 2,400 – 2,900 tonnes of V₂O₅
• Following the successful completion of planned kiln refractory maintenance in Q1 2024, the Company achieved improved production rates in Q2 2024
• Global V₂O₅ recovery rate³ of 74.3% in Q2 2024 vs. 81.0% in Q2 2023
• Ilmenite concentrate production continued to ramp up in Q2 2024 with 8,625 tonnes produced
• V₂O₅ equivalent sales of 1,841 tonnes (inclusive of 128 tonnes of purchased material) in Q2 2024 vs. 2,557 tonnes sold in Q2 2023 due to lack of material availability following lower production in Q1 2024
• In Q2 2024, the Company sold 12,261 tonnes of ilmenite concentrate, exceeding the guidance range of 9,500 to 11,500 tonnes; This increase was primarily due to the anticipated catch-up in sales from Q1 2024
• In Q2 2024, the average benchmark price per lb of V₂O₅ in Europe was $5.93, representing a 30% decrease from the Q2 2023 average of $8.46, driven by continued softer demand in the spot market

TORONTO / Jul 17, 2024 / Business Wire / Largo Inc. ("Largo" or the "Company") (TSX: LGO) (NASDAQ: LGO) today announces quarterly production of 2,689 tonnes (5.9 million lbs¹) and sales of 1,841 tonnes of vanadium pentoxide (“V₂O₅”) equivalent, respectively, in Q2 2024.

Daniel Tellechea, Interim CEO and Director of Largo, stated: “Our second quarter results reflect the successful completion of planned maintenance and a return to expected production levels. Focusing on operational efficiencies remains essential as we work to maintain production targets for the second half of the year, which will support meeting our sales goals. Additionally, our ongoing efforts to ramp up ilmenite production are key to diversifying our revenue streams, especially in the current environment of lower vanadium prices. By continuing to enhance our operational processes and address logistical challenges, we aim to ensure consistent production and reliable supply to our customers going forward.”

Maracás Menchen Mine Operational and Sales Results

Q2 2024 Additional Highlights

• Improved V₂O₅ Production in Q2 2024 Following Completion of Q1 2024 Maintenance: V₂O₅ production from the Maracás Menchen Mine was 753 tonnes in April, 1,012 tonnes in May and 924 tonnes in June for a total of 2,689 tonnes produced in Q2 2024. In Q2 2024, global recoveries³ averaged 74.3%, a decrease of 8% from the 81.0% averaged in Q2 2023. The global recovery³ was impacted by lower magnetic and V₂O₅ grades in the processed ore. The Company mined 568,588 tonnes of ore with an effective V₂O₅ grade² of 0.69% in Q2 2024 compared to 489,892 tonnes with an effective V₂O₅ grade² of 0.86% in Q2 2023 and 604,231 tonnes with an effective V₂O₅ grade² of 0.53% in Q1 2024, representing a 16% increase in total ore mined over the prior comparative quarter. Total ore crushed was 640,008 tonnes in Q2 2024, being 24% higher than Q1 2024 and 44% higher than the 445,026 tonnes crushed in Q2 2023. The Company continues to increase its mined and crushed ore throughput in order to achieve its set production targets in accordance with its 2024 mining plan. The Company also produced 115,075 tonnes of concentrate with an effective grade² of 2.95% in Q2 2024.
• Q2 2024 V₂O₅ Equivalent Sales Align with Material Availability from Q1 2024 Production: In Q2 2024, V₂O₅ equivalent sales of 1,841 tonnes (which includes 128 tonnes of purchase material sold) represented a 28% decrease in tonnes sold over Q2 2023. Lower sales in Q2 2024 were largely a result of decreased material availability from lower production in Q1 2024 due to previously reported and planned maintenance. In Q2 2024, lower spot market demand continued mainly caused by a decreased demand from the Chinese and European steel sectors. The Company produced approximately 26% of its quarterly production as high purity material in Q2 2024. The Company continues to actively manage its logistics and supply chain operations to ensure the delivery of premium products and services to its customers. In Q2 2024, shipment operations from Brazil faced challenges due to congestion and delays, particularly in Asia.
