Paulo Misk, President and CEO of Largo, stated: "Despite operational challenges faced in 2022, we continue to prioritize and focus on the steady state operation of our Maracás Menchen Mine in Brazil. To ensure normal operating performance throughout 2023, our operational team performed mitigation efforts to rectify rain-related impacts and preventive maintenance measures during the operational downtime in December 2022 and January 2023."

He continued: "In the coming year, we expect to meet our planned objectives to fully realize the value of our tier one vanadium company, including annual guidance for 2023, the completion of our ilmenite concentration plant, and the delivery of our inaugural VRFB for Enel in the second quarter of 2023." He concluded: "While our negotiation with Ansaldo continues, LCE's senior management continue to maintain their efforts on core development and system improvements required to support the current and future needs of the long duration energy storage sector. We are pleased to see a strengthening in vanadium demand, driven by strong high purity aerospace inquiries and new VRFB deployments, which has led to price increases in recent months."

Maracás Menchen Mine Operational and Sales Results

Q4, FY 2022 and Other Highlights

• Quarterly Operational Results Impacted by a Mining Contractor Change, Mine Sequencing and Heavy Rainfall: In Q4 2022, V₂O₅ production from the Maracás Menchen Mine of 2,004 tonnes was in line with the 2,003 tonnes produced in Q4 2021. As a result of the Company's mining contractor transition and corrective maintenance at the leaching and deammoniator areas, 804 tonnes of V₂O₅ were produced in October 2022. Production of 605 tonnes in November 2022 was affected by changes in mining sequence and 596 tonnes in December 2022 was affected by heavy rains at the Company's operations. Annual V₂O₅ production was 10,436 tonnes in 2022, being largely in line with the 10,319 tonnes produced in 2021. Lower annual production was due to preventative and corrective maintenance at Company's plant facility in Maracás in Q1 2022, a planned kiln and cooler refractory refurbishment in Q3 2022 and heavy rainfall in December. In Q4 2022, global recoveries³ averaged 74.7% as compared to the 76.0% averaged in Q4 2021. The Company achieved an annual average global V₂O₅ recovery³ rate of 79.1% in 2022. The Company mined 1,359,927 tonnes of ore with an effective V₂O₅ grade² of 1.11% in 2022 compared to 1,248,967 tonnes with an effective V₂O₅ grade² of 1.12% in 2021. The impact on the Company's global recovery³ and mined ore in 2022 is primarily due to the reasons mentioned above.
• Rainfall Impact and Mitigation Efforts - Impacts to January 2023 Production and Sales Expected: Despite rain-related mitigation efforts implemented at the end of 2021, the Company's Maracás Menchen Mine experienced approximately 36% more rainfall in December 2022 compared to December 2021, and more than 76% more rainfall on a single day during the same comparative month. This resulted in approximately 16 days of operational downtime in December 2022 and January 2023, during which time the Company performed preventative maintenance measure such as kiln refractory and electrostatic precipitator ("ESP") repairs, previously planned for February 2023. In 2021, the Company constructed a diversion channel surrounding the Campbell Pit and upgraded its pumping system capacity to mitigate rainwater accumulation inside the pit. In December 2022, the diversion channel successfully mitigated rain from entering the pit downstream, however, unexpected levels of heavy rainfall caused significant rainfall accumulation inside the pit. The Company plans to further upgrade its pumping system capacity and expects to build additional mined material stockpiles in 2023 to mitigate impacts to mining operations going forward. As a result of these rain-related impacts in December 2022 and January 2023, the Company expects Q1 2023 production and sales ranges of 1,900 - 2,200 tonnes and 2,300 - 2,500 tonnes, respectively.
• Annual Sales Results Within Guidance - Vanadium Prices Reflect Increase in Demand: In Q4 2022, V₂O₅ equivalent sales were 2,774 tonnes (inclusive of 118 tonnes of purchased material), representing a 4% decrease over Q4 2021. Total V₂O₅ equivalent sales were 11,091 tonnes (inclusive of 1,057 tonnes of purchased material) in 2022, representing a 3% decrease over 2021. Lower sales in Q4 were impacted by the effects of lower production. Stronger vanadium prices exiting the quarter reflected an increase in demand from the high purity aerospace sector and continued growth in VRFB deployments, particularly in China. The average benchmark price per lb of V₂O₅ in Europe was $9.44 exiting the quarter, representing an increase of approximately 20% from the lows of 2022. As of January 20, 2023, the benchmark price per lb of V₂O₅ in Europe was $10.08.
• Inaugural VRFB Deployment Progress: During Q4 2022, LCE continued to make additional progress on the delivery of the Enel Green Power España ("EGPE") contract. Substantially all of the hardware is either in transit or ready for installation at the deployment site in Spain. The remaining items to be shipped are six of the twelve electrolyte storage containers, which will be shipped in February 2023 and installed in March 2023. Additionally, the Company expects the installation and interconnection of the AC and DC power systems to be completed in Q1 2023. The hot commissioning of the VRFB system as well as provisional acceptance, which requires the completion of as-build drawings, manuals, final punch-list items, and operational testing by EGPE is expected to be completed in Q2 2023.
• New Debt Facilities Secured in Brazil: In December 2022, the Company secured an additional debt facility of $20.0 million with a bank in Brazil. The facility is for three years, with a 360-day grace period and equal principal repayments due every six months until maturity following the grace period. In addition to a fee of 0.7%, accrued interest at a rate of 8.20% p.a. is to be paid every six months until maturity. In January 2023, the Company secured two additional debt facilities with banks in Brazil. The first facility of $15.0 million is for two years, with a 180-day grace period and equal principal repayments due every three months until maturity following the grace period. In addition, accrued interest at a rate of 6.85% p.a. is to be paid every three months. The second facility of $10.0 million is for three years, with a 360-day grace period and equal principal repayments due every six months until maturity following the grace period. In addition to a fee of 0.7%, accrued interest at a rate of 8.36% p.a. is to be paid every six months. A portion of the December 2022 debt facility was used in December 2022 to repay the Company's existing $15.0 million debt facility secured in April 2022 and due for repayment in April 2023, with the remaining debt facilities primarily being used to address working capital pressures caused by ongoing capex projects in the first six months of 2023.

2023 Production, Sales and Cost Guidance

Tables summarizing the Company's 2023 production, sales and cost guidance is provided below. It is expected that the Company will incur higher cash operating costs excluding royalties⁴ in the first half of 2023 as a result of lower sales in H1 2023, a result of previously noted rain-related operational impacts in Q4 2022 and Q1 2023. In H1 2023, the Company anticipates cash operating costs excluding royalties⁴ to be above the average cost guidance provided for 2023 with H2 2023 being closer to the lower end.

2023 Capital Expenditures Guidance

In 2023, the Company plans to invest approximately $50.5 million on capital expenditures of which approximately $4.0 million has been carried over from the 2022 capital expenditures budget. The $48.0 million capital expenditure budget includes approximately $12.5 million for sustaining capital requirements, $12.5 million for capitalized stripping, $18.0 million to finalize the construction of the Company's ilmenite concentration plant and $2.5 million for the installation of an additional dry magnetic separator to assist with the Company's mining operations in Brazil.

Management has made the decision to postpone the Company's existing plans to further develop its titanium dioxide ("TiO₂") pigment plant until additional funds are made available, either internally or externally. At this time, the Company is exploring alternative debt financing or strategic association options with advisors and will provide an update as things progress.

Non-GAAP⁵ 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 and sales, 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 conversion costs, product acquisition costs, distribution 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. This measure differs to the new total cash costs non-GAAP measure the Company uses to measure its overall performance (see Company's latest Management Discussion and Analysis). 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.
