Largo Reports Fourth Quarter and Full Year 2021 Operational Results; Sales Exceeds Lower End of Guidance Despite Rain-Related Production Disruption in November-December; Provides 2022 Guidance

Largo Inc. ("Largo" or the "Company") (TSX: LGO) (NASDAQ: LGO) today announces annual production of 10,319 tonnes (22.7 million lbs¹) of vanadium pentoxide (“V₂O₅”) and sales 11,393 tonnes of V₂O₅ equivalent from its Maracás Menchen Mine in 2021.

Paulo Misk, President and CEO of Largo, stated: “Despite encountering global logistical delays throughout the year and heavy rains in Brazil in Q4 2021, our team adapted to the challenges presented and managed to exceed the lower range of the Company’s vanadium sales guidance in 2021. I am also pleased to report the Company had a strong finish to the year with V₂O₅ equivalent sales of 1,029 tonnes in December. Abnormally elevated levels of rainfall in November and December significantly impacted operational results at the MaracásMenchen Mine in Q4 2021 which our operations team worked diligently to implement an effective divert channel system that is expected to prevent heavy rainfall impacts in the future. The Company returned to normalized production levels following the planned 6-day maintenance shutdown which took place early in January.”

He concluded: “Looking ahead, the Company remains focused on completing a significant milestone following the delivery of its first VCHARGE VRFB to Enel in Q3 2022 and will begin executing Phase 1 of its operational plan as presented in the Company’s recently released technical report for the Maracás complex in Brazil. We believe the expected incremental cash flows generated by the production and sale of ilmenite concentrate and TiO₂ pigment and future planned expansion of vanadium production will provide clear value creation upside to our shareholders going forward. 2022 will undoubtedly present new challenges for our team but we remain focused on the tremendous growth opportunity that exists in our profitable vanadium business and our vanadium-based energy storage business from the deployment of additional VRFB systems expected in the years ahead.”

Q4 and FY 2021 Operational Highlights

• Operational Results Largely Impacted by Heavy Rainfall in Maracás: Production from the MaracásMenchen Mine was 2,003 tonnes of V₂O₅ in Q4 2021, representing a decrease of 40% over Q4 2020, which was historically the Company’s strongest production quarter. Lower quarterly production was due to heavy rainfall at the Company’s Maracás operation in November and December. Annual V₂O₅ production was 10,319 tonnes in 2021, being 13% lower than 2020. Lower annual production was due to the commissioning and ramp up activities associated with the Company’s kiln and cooler upgrades in Q1 2021 and heavy rainfall in November and December. In Q4 2021, global recoveries³ averaged 76.0% as compared to the 80.6% averaged in Q4 2020. The Company achieved an annual average global V₂O₅ recovery³ rate of 79.7% in 2021, representing a 2.0% decrease over the 81.4% averaged in 2020. The Company mined 1,248,967 tonnes of ore with an effective V₂O₅ grade² of 1.00% in 2021 compared to 1,087,518 tonnes with an effective V₂O₅ grade² of 1.29% in 2019. The decrease in global recoveries³ and mined ore in 2021 is primarily due to the impacts mentioned above.
• Lower End of Annual Sales Guidance Met: In Q4 2021, V₂O₅ equivalent sales were 2,899 tonnes, representing a 23% decrease over Q4 2020. Total V₂O₅ equivalent sales of 11,393 tonnes in 2021 exceeded the lower end of the Company’s 2021 annual sales guidance (11,200 – 11,800 tonnes) and were 11% higher than total sales in 2020. The Company continued to navigate challenges presented by global logistical delays in Q4 2021, which have impacted all aspects of the Company’s supply chain.
• Summary of Rainfall Effects and Drainage Improvements: During November and December, higher than expected rain volume of approximately 580 millimeters fell in Maracás, representing an increase of 690% over monthly rainfall average (2014 – 2020) and 360% over the rainfall average for the Q4 period (2014 – 2020). Following impacts in Q4 2021 from abnormally higher rainfall levels, the Company installed a rainwater diversion system surrounding the Campbell Pit and has revamped its pumping system. The Company expects that these actions will prevent future impacts to operations from higher-than-expected rainfall.
• Vanadium Trioxide (“V₂O₃”) Plant: In Q4 2021, the Company completed the ramp up of its V₂O₃ plant and provided samples to prospective clients for product specification analysis. The Company expects to begin shipping V₂O₃ to customers in Q1 2022.

2022 Production, Sales and Cost Guidance

The Company has provided solid production, sales and cost guidance for 2022 and management expects to maintain its global competitive position in the vanadium sector. A table summarizing 2022 production, sales and cost guidance has been provided below:

2022 Capital Expenditures Guidance

In 2022, the Company plans to invest approximately $64.0 million on capital expenditures of which approximately $2.0 million has been carried over from the 2021 capital expenditures budget. The $64.0 million capital expenditure budget includes approximately $9.5 million for sustaining capital requirements, $10.5 million for capitalized stripping, $29.5 million for the construction of the Company’s ilmenite concentration plant, $9.5 million for its TiO₂ processing plant and $2.0 million for additional LCE development. For its ilmenite concentration plant project, the Company’s current capex plans increased by $6.8 million versus its prior estimate (see press release dated March 18, 2021) due to the incorporation of improvements in its ilmenite concentration which should increase ilmenite concentrate grades to above 45% TiO₂ from 40%. The increase in overall capital expenditures versus prior years will allow Largo to advance its planned growth projects to enhance future profitability and market competitiveness. The Company expects to fund these capital expenditure projects through internal cash flows.

Non-GAAP⁶ Measures

The Company uses certain non-GAAP financial performance measures in this press release, which are described in the following section.

Cash Operating Costs

The Company’s press release refers to cash operating costs per pound, a non-GAAP performance measure, in order to provide investors with information about a key measure used by management to monitor performance. This information is used to assess how well the Maracás Menchen Mine is performing compared to plan and prior periods, and also to assess its overall effectiveness and efficiency. Cash operating costs includes mine site operating costs such as mining costs, plant and maintenance costs, sustainability costs, mine and plant administration costs, royalties, general and administrative costs (all for the mine properties segment), but excludes depreciation and amortization, share-based payments, foreign exchange gains or losses, commissions, reclamation, capital expenditures and exploration and evaluation costs. Operating costs not attributable to the mine properties segment are also excluded, including product acquisition costs and inventory write-downs. These costs are then divided by the pounds of vanadium sold that were produced by the Maracás Menchen Mine to arrive at the cash operating costs per pound. Prior to 2020, these costs were divided by the pounds of production from the Maracás Menchen Mine, rather than pounds sold. These measures, along with revenues, are considered to be one of the key indicators of the Company’s ability to generate operating earnings and cash flow from its Maracás Menchen Mine. These cash operating costs measures do not have any standardized meaning prescribed by IFRS and differ from measures determined in accordance with IFRS. These measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures are not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.

¹ Conversion of tonnes to pounds, 1 tonne = 2,204.62 pounds or lbs.

² Effective grade represents the percentage of magnetic material mined multiplied by the percentage of V2O5 in the magnetic concentrate.

³ Global recovery is the product of crushing recovery, milling recovery, kiln recovery, leaching recovery and chemical plant recovery.

⁴ Cash operating costs excluding royalties per pound reported are on a non-GAAP basis. Refer to the “Non-GAAP Measures” section of this press release.

⁵ Includes capitalized waste stripping costs.

⁶ GAAP – Generally Accepted Accounting Principles

⁷ Drilling and engineering work performed on the Campbell Pit, and NAN and GAN deposits, in addition to the inclusion of titanium dioxide (“TiO2”) has resulted in a significant increase in reserves and resources
