Financial and Operating Results – Highlights

Q4 & Full Year 2023 Notes and Other Highlights

• The Company recorded a net loss of $32.4 million in 2023 compared with a net loss of $2.2 million in 2022, largely driven by a 13% decrease in revenues and an increase in certain expenses, most notably a 3% increase in operating costs, a 506% increase in finance costs, a 195% increase in exploration and evaluation costs and a write down of vanadium assets of $4.9 million.
• In 2023, the Company saw increased direct mine and production costs, primarily due to an increase in total ore mined in 2023, the cost impacts of low ore availability experienced earlier in the year and plant shutdowns for corrective maintenance during 2023. The Company's direct mine and production costs decreased in Q4 2023 as compared with Q4 2022, reflecting the impact of the cost saving and operational improvement initiatives implemented at the mine, as well as the softening of prices for critical consumables.
• The Company continues to actively work towards achieve higher levels of operational efficiency to better manage its costs as it navigates lower grades of ore mined as compared with prior years. In Q4 2023, V ₂ O ₅ equivalent production was 28% higher than the 2,163 tonnes produced in Q3 2023 and 38% higher than the 2,004 tonnes produced in Q4 2022. The global recovery ⁷ achieved in Q4 2023 was 79.4%, an increase of 6.3% from the 74.7% achieved in Q4 2022 and 3.3% higher than the 76.9% achieved in Q3 2023. The total ore mined in Q4 2023 was 473,958 tonnes, an increase of 45% in comparison with Q4 2022. 1,752,982 tonnes of ore were mined in 2023, an increase of 29% as compared with 2022. Actions were taken to increase crushing availability and normal production levels were recovered in Q4 2023. Total ore crushed in Q4 2023 was 8% higher than in Q3 2023 and 35% higher than in Q4 2022. For 2023, total ore crushed was 9% higher than in 2022.
• For 2023, total professional, consulting and management fees decreased by 9% from 2022 and other general and administrative expenses decreased by 18% from 2022, both as a result of reduced activity and headcount at LCE as a result of the initiation of the strategic review. Additionally, technology start-up costs decreased by 52% in 2023 compared with 2022 primarily due to a write down of battery components inventory in Q4 2022 of $6.4 million and a decrease in activities at LCE in Q4 2023 as the installation of its battery project nears conclusion.
• In 2021, the Company signed a 10-year exclusive off-take agreement with Gladieux Metals Recycling (" GMR ") for the purchase of all standard and high purity grade vanadium products GMR produces. The Company is committed to the purchase of a minimum of 360 tonnes of V ₂ O ₅ in 2024 and its onward distribution to customers.
• Subsequent to Q4 2023, production in January 2024 was 582 tonnes of V ₂ O ₅ equivalent with 276 tonnes of V ₂ O ₅ equivalent produced in February 2024. Lower production achieve in the first two months of Q1 2024 is attributable to the Company's previously announced kiln refractory maintenance. Subsequent to Q4 2023, sales in January 2024 were 1,072 tonnes of V ₂ O ₅ equivalent, with 1,065 sold in February 2024.

Non-GAAP ⁸ Measures

The Company uses certain non-GAAP measures in this press release, which are described in the following section. Non-GAAP financial measures and non-GAAP ratios are not standardized financial measures under IFRS, the Company's GAAP, and might not be comparable to similar financial measures disclosed by other issuers. 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. Management believes that non-GAAP financial measures, when supplementing measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company.

Revenues Per Pound Sold

This press release refers to revenues per pound sold, a non-GAAP performance measure that is used to provide investors with information about a key measure used by management to monitor the performance of the Company.

This measure, along with cash operating costs and total cash costs, is 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 and sales activities. This revenues per pound sold measure does not have any standardized meaning prescribed by IFRS and differs from measures determined in accordance with IFRS. This measure is 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. This measure is not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.

The following table provides a reconciliation of this measure per pound sold to revenues as per the Q4 2023 and annual unaudited condensed interim consolidated financial statements.

Cash Operating Costs Excluding Royalties Per Pound

The Company's press release refers to cash operating costs excluding royalties per pound, which are non-GAAP ratios based on cash operating costs and cash operating costs excluding royalties, which are non-GAAP financial measures, 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.

Cash operating costs excluding royalties is calculated as cash operating costs less royalties. Cash operating costs per pound and cash operating costs excluding royalties per pound are obtained by dividing cash operating costs and cash operating costs excluding royalties, respectively, by the pounds of vanadium equivalent sold that were produced by the Maracás Menchen Mine. Cash operating costs, cash operating costs excluding royalties, cash operating costs per pound and cash operating costs excluding royalties per pound, along with revenues, are considered to be key indicators of the Company's ability to generate operating earnings and cash flow from its Maracás Menchen Mine. These measures differ from measures determined in accordance with IFRS, and are not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.

The following table provides a reconciliation of cash operating costs and cash operating costs excluding royalties, cash operating costs per pound and cash operating costs excluding royalties per pound for the Maracás Menchen Mine to operating costs as per the 2023 annual consolidated financial statements.

EBITDA and Adjusted EBITDA

The Company's press release refers to earnings before interest, tax, depreciation and amortization, or "EBITDA", and adjusted EBITDA, which are non-GAAP financial measures, in order to provide investors with information about key measures used by management to monitor performance. EBITDA is used as an indicator of the Company's ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures.

Adjusted EBITDA removes the effect of inventory write-downs, impairment charges (including write-downs of vanadium assets), insurance proceeds received, movements in legal provisions, non-recurring employee settlements and other expense adjustments that are considered to be non-recurring for the Company. The Company believes that by excluding these amounts, which are not indicative of the performance of the core business and do not necessarily reflect the underlying operating results for the periods presented, it will assist analysts, investors and other stakeholders of the Company in better understanding the Company's ability to generate liquidity from its core business activities.

EBITDA and adjusted EBITDA are intended to provide additional information to analysts, investors and other stakeholders of the Company and do not have any standardized definition under IFRS. These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures exclude the impact of depreciation, costs of financing activities and taxes, and the effects of changes in operating working capital balances, and therefore are not necessarily indicative of operating profit or cash flow from operating activities as determined under IFRS. Other companies may calculate EBITDA and adjusted EBITDA differently.

The following table provides a reconciliation of EBITDA and adjusted EBITDA to net income (loss) as per the 2023 annual consolidated financial statements.
