Largo Reports Third Quarter 2023 Production and Sales Results and Begins Hot Commissioning of its 6.1 MWh Vanadium Redox Flow Battery; Production and Cost Guidance Remains Unchanged

Q3 2023 and Other Highlights

• V₂O₅ production of 2,163 tonnes (4.8 million lbs¹) vs. 2,906 tonnes produced in Q3 2022, including 644 tonnes in July, 775 tonnes in August and 744 tonnes in September
• Global V₂O₅ recovery rate³ of 76.9% in Q3 2023 vs. 80.7% in Q3 2022
• V₂O₅ equivalent sales of 2,385 tonnes vs. 2,796 tonnes sold in Q3 2022
• The average benchmark price per lb of V₂O₅ in Europe was $8.03, a 2.5% decrease from the average of $8.23 seen in Q3 2022
• Ramp up of its new ilmenite concentration plant continues with ilmenite concentrate production of 350 tonnes in August and 700 tonnes in September
• Largo Clean Energy ("LCE") completed site acceptance testing of its Enel Green Power España ("EGPE") 6.1 MWh vanadium redox flow battery ("VRFB") deployment and submitted results to EGPE, with the expectation of completing the hot commissioning phase of the battery; Provisional acceptance is expected in Q4 2023
• 2023 production, sales, cost and capital expenditures guidance remain unchanged

Largo Inc. ("Largo" or the "Company") (TSX: LGO) (NASDAQ: LGO) today announces quarterly production of 2,163 tonnes (4.8 million lbs¹) and sales of 2,385 tonnes of vanadium pentoxide ("V₂O₅") equivalent, respectively, in Q3 2023.

Daniel Tellechea, Interim CEO and Director of Largo, stated: "Despite production setbacks in the third quarter caused by the previously reported accident in our chemical plant and delays in the ramp of our new magnetic separator in the crushing plant, Largo remains steadfast in its commitment to rectifying operations in the fourth quarter and has maintained its production, cost and capex guidance for 2023. Our top priority is safety and returning production to a more normalized level through the strengthening of operational efficiencies at the mine and crushing plant." He continued: "On the Largo Clean Energy front, we are pleased that hot commissioning and provisional acceptance of the EGPE 6.1 MWh VRFB deployment are in the final stages of completion, marking an exciting step towards the conclusion of LCE's inaugural vanadium battery project. Furthermore, the review of strategic alternatives to unlock and fully maximize the value of LCE remains ongoing and has garnered interest from various parties thus far. While near-term vanadium demand and prices are challenging on the back of weak demand from the steel sector, we are optimistic about future demand projections, particularly driven by an explosive growth of future VRFB deployments in the coming years."

Maracás Menchen Mine Operational and Sales Results

Q3 2023 and Other Additional Highlights

• Despite higher mining throughput in Q3 2023 (447,165 tonnes) compared with Q3 2022 (351,450 tonnes), V₂O₅ production from the Maracás Menchen Mine was impacted in July and August as a result of the accident at the chemical plant in July, while production in September was affected by the lack of availability of the crushing circuit in September. Mitigative measures to increase production levels in future quarters, including increasing crusher availability and recommissioning evaporation sections of the chemical plant are underway. High purity V₂O₅ equivalent production represented 38% of the total quarterly production in Q3 2023.

• The global recovery³ achieved in Q3 2023 was 76.9%, representing a 5% decrease from the 80.7% achieved in Q3 2022 and 5% lower than the 81.0% achieved in Q2 2023. The global recovery³ in July was 78.8%, with 77.7% achieved in August and 73.6% achieved in September. Lower recovery levels achieved during the quarter relate production impacts mentioned previously. The Company produced 87,447 tonnes of concentrate with an effective grade² of 2.94%.

• V₂O₅ equivalent sales of 2,385 tonnes (inclusive of 256 tonnes of purchase material) were in line with expectations for Q3 2023 but represented a 17% decrease in tonnes sold over Q3 2022. The Company's sales remain geographically diversified, with North America and Europe each representing approximately one third of total sales, and South America and Asia representing the remaining third. Spot demand was soft in Q3 2023, primarily due to adverse conditions in the Chinese and European steel industries. However, strong demand for high purity vanadium products continued.

• Effective Monday, October 9, 2023, Mr. Celio Pereira assumed the role of Chief Operating Officer (COO) of Largo Vanádio de Maracás S/A ("LVMSA"). This decision follows the departure of Álvaro Resende, to whom the Company thanks for his many years of service. Celio's appointment is a testament to his excellent track record and the trust and confidence placed in him by the Board and management of Largo. Celio brings to LVMSA over 8 years of operational and technical expertise, honed during his tenure at the Maracás Menchen Mine. He will be instrumental in implementing a culture of safety and operational efficiency at the mine. Following this operational restructuring, the Company expects an enhancement in operational efficiencies at the crushing and milling circuits, as well as the increasing throughput to the ilmenite plant.
