During the fourth quarter of 2023 and the first and second quarter of 2024, the Company's cash operating costs excluding royalties per pound¹ were impacted by certain non-recurring items, mainly the impact of write-downs of the Company's produced vanadium finished product inventories due to the declining price environment. These write-downs do not fully represent the Company's ongoing operational efficiency or the success of its cost reduction initiatives, especially when presented on a cost per pound basis. When these adjustments are excluded, the underlying unit costs more accurately demonstrate Largo's sustained focus on optimizing its cost structure.

The table below provides a detailed breakdown of the Company's cash operating costs per pound sold¹:

Daniel Tellechea, Director and Interim CEO of Largo, commented: "We believe it is important to communicate to our stakeholders that the Company's ongoing efforts to streamline operations and reduce costs are beginning to bear fruit, as evidenced by the declining trend in our unitary cash costs at the Maracás Menchen Mine. Despite the impact of non-recurring items in recent quarters, our team remains laser-focused on achieving further efficiencies, ensuring that Largo is well-positioned to navigate current market challenges and deliver long-term value to our shareholders."

Non-GAAP² 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.

Cash Operating Costs Per Pound

The Company's press release refers to cash operating costs per pound and 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 its plan and prior periods, and to 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 Q2 2024 unaudited condensed interim consolidated financial statements.

¹ The cash operating costs excluding royalties and adjusted cash operating costs excluding royalties are reported on a non-GAAP basis. Refer to the "Non-GAAP Measures" section of this press release.
