Largo Resources Ltd. (" Largo " or the " Company ") ( TSX: LGO ) ( NASDAQ: LGO ) today announces its second quarter 2021 financial results highlighted by revenues of $54.3 million and net income of $8.4 million.

Strategic Updates

During the second quarter, the Company hosted an investor-oriented virtual ‘Battery Day' during which the Company discussed its transformational strategic shift to the production of vanadium based electrical energy storage systems. The Company believes that moving to vertically integrate its financially strong vanadium operations with its superior long duration energy storage technology will present a higher value market opportunity for the Company's vanadium products in the future and will also create a unique competitive advantage for Largo in the rapidly growing long duration energy storage market.

Aligned with its belief in the opportunities expected to arise in the transition to VRFB production, the Company announced the appointment of Mr. Ian Robertson as Co-Chair of the Board of Directors of the Company and as Interim President of LCE. During the quarter, the Company continued to augment its strategic, commercial, technical and manufacturing teams including the appointment of Mr. Salvatore Minopoli as VP of LCE Operations.

During the quarter, LCE secured a facility in Massachusetts, U.S. for its global headquarters, including its product development and stack manufacturing centre, which is sufficiently sized to support a manufacturing capacity of energy systems representing up to 1.4 gigawatt hours of storage per year. The team moved into the office facility in May 2021 and building modifications are underway for the installation and commissioning of the stack manufacturing capacity and test equipment required to support the business plan.

On July 20, 2021, the Company announced that LCE had entered into its first VCHARGE± VRFB sales contract with EGPE and has now received notice to proceed for this installation. Under the contract, LCE is obligated to deliver a five hour, 6.1 MWh VCHARGE± system for a project in Spain with expected commissioning in Q4 2022.

With respect to continued VRFB deployments, LCE is focused on obtaining the required regulatory certification to support expected 2022 project sales, with certifications on track to be received by the end of Q4 2021. In addition, the Company is progressing with establishing the supply chain and resources required to deliver on the anticipated project deployment timelines and cost targets.

Ian Robertson, Co-Chair of Largo, stated: "During our Battery Day we confirmed our belief that vertically integrating our highly efficient vanadium production capacity with our superior vanadium based energy storage technology will present a more financially and societally valuable proposition for the Company. I am pleased with the recently announced milestone energy storage system sales contract with a world-class partner and remain confident that it represents validation of the transformational opportunity to generate substantial long-term value for the Company. Looking ahead, we see the planned change in our name to "Largo Inc." as evidence of the Company's confidence in the significant opportunity that exists for Largo to profitably participate in the growing long duration energy storage market. We expect to proceed with the Company's name change and extensive rebrand in late Q3 2021."

Paulo Misk, President and Chief Executive Officer for Largo, stated: "Continued momentum across all key markets resulted in increased vanadium demand and strong revenue growth for the Company in Q2 2021. This has led to a substantial increase in revenues per lb ² sold of 119% over Q2 2020 and contributed to healthy cash flow generation, building upon our solid cash position. Following the additional debt funding obtained in Q2 2021 of $15 million, the Company exited the quarter with a cash balance of $80.7 million. We will continue to capitalize on the strong demand in the vanadium markets we serve with the goal of improving profit margins going forward."

Operational and Financial Updates

A summary of the Company's operational and financial performance for the second quarter 2021 is provided below:

Financial

Maracás Menchen Mine Production and Sales

Q2 2021 Financial Results

The Company recorded net income of $8.4 million and basic earnings per share of $0.13 in Q2 2021, compared with a net loss of $7.0 million in Q2 2020.

During Q2 2021, the Company recognized revenues of $54.3 million from sales of 3,027 tonnes of V ₂ O ₅ equivalent (Q1 2020 - 1,018 tonnes). This represents a 546% increase in revenues over Q2 2020 ($8.4 million). Revenues per pound sold ² were $8.14 in Q2 2021 compared to $3.72 per pound sold in Q2 2020, representing an increase of 119%.

Operating costs of $35.0 million in Q2 2021 (Q2 2020 - $9.6 million) include direct mine and production costs of $19.6 million (Q2 2020 - $2.2 million), conversion costs of $2.4 million (Q1 2020 - $nil), product acquisition costs of $3.7 million (Q1 2020 - $2.4 million), royalties of $2.4 million (Q2 2020 - $1.3 million), distribution costs of $1.3 million (Q1 2020 - $0.3 million) and depreciation and amortization of $5.6 million (Q2 2020 - $2.0 million). The increase in direct mine and production costs is primarily attributable to the increase in sales of V ₂ O ₅ equivalent sold in Q2 2021. Operating costs in Q2 2021 were partially offset by a margin on iron ore sales of $0.1 million (Q2 2020 - $nil). Further, conversion costs relate to the costs incurred in converting quantities of V ₂ O ₅ into ferrovanadium for delivery to customers and distribution costs relate to the costs incurred in delivering products to customers. In Q2 2020, the Company only sold V ₂ O ₅ and had only just begun shipping products to its customers.

Cash operating costs excluding royalties ¹ were $3.39 per lb in Q2 2021, compared with $1.89 for Q2 2020. The increase seen in Q2 2021 compared with Q2 2020 is largely due to a decrease in the global recovery ⁵ , with 79.9% achieved in Q2 2021, compared with 80.8% achieved in Q2 2020, and the impact of higher costs arising from the planned shutdown in Q1 2021.

Professional, consulting and management fees were $4.4 million in Q2 2021, compared with $1.2 million in Q2 2020. The increase is primarily attributable to costs incurred in Q2 2021 in connection with LCE that was not operational in Q2 2020. In addition, the Company's Corporate segment incurred increased legal and regulatory costs in Q2 2021 in relation to the Nasdaq listing process and U.S. regulatory requirements.

The foreign exchange gain in Q2 2021 increased from Q2 2020 by 184% to $3.1 million. This is primarily attributable to a weakening of the U.S. dollar against the Brazilian real by approximately 12% since March 31, 2021 on U.S. dollar denominated cash and liabilities in Brazil and a strengthening of the Canadian dollar against the U.S. dollar by approximately 2% since March 31, 2021 on Canadian dollar denominated assets.

Cash provided by operating activities of $19.1 million in Q2 2021 is an increase from cash used in operating activities of $63.6 million in Q2 2020. This is primarily due to an increase in cash provided before working capital items of $15.2 million and a net increase in working capital items of $67.6 million. The net movement in working capital items is largely driven by increases in amounts receivable and inventory balances in Q2 2021 and a payment to the Company's former off-take partner in Q2 2020 in partial settlement of trade payables.

Q2 2021 Operational Results

Total production from the Maracás Menchen Mine was 3,070 tonnes of V ₂ O ₅ , representing an increase of 20% over Q2 2020 and a 55% increase over Q1 2021. This increase is attributable to the kiln upgrades and cooler improvements implemented in January 2021, as well as the impact of preventative maintenance in the chemical plant in Q2 2020. V ₂ O ₅ production in April 2021 was 1,092 tonnes, with 1,075 tonnes produced in May and 903 tonnes produced in June. The lower production in June was due to a reduction in the total material mined that occurred during the transition between mining contractors that was completed by the end of Q2 2021. Subsequent to Q2 2021, production in July was 1,068 tonnes of V ₂ O ₅ .

The global recovery ⁵ achieved in Q2 2021 was 79.9%, 1% lower than the 80.8% achieved in Q2 2020 and 3% higher than the 77.4% achieved in Q1 2021. The global recovery in April was 78.8%, with 78.5% achieved in May and 82.0% achieved in June. The Company expects the global recovery ⁵ to stabilize at the levels seen in 2020 upon the completion of the commissioning and ramp up period for the kiln improvements implemented in Q1 2021.

In Q2 2021, 340,734 tonnes of ore were mined with an effective grade ⁴ of 1.15% of V ₂ O ₅ . The ore mined in Q2 2021 was 32% higher than in Q2 2020. The Company produced 98,372 tonnes of concentrate with an effective grade ⁴ of 3.23%.

Non-GAAP ⁶ Measures

The Company uses certain non-GAAP financial performance measures in its press release and MD&A, which are described in the following section.

Revenues Per Pound

The Company's 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 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 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 Q2 2021 unaudited condensed interim consolidated financial statements.

1. As per note 19 of the Company's Q2 2021 unaudited condensed interim consolidated financial statements.

Cash Operating Costs Per Pound

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 later in this section).

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.

In addition, the Company's press release refers to cash operating costs excluding royalties. This is a non-GAAP performance measure and is calculated as cash operating costs less royalties, as disclosed in the following table.

The following table provides a reconciliation of cash operating costs per pound for the Maracás Menchen Mine to operating costs as per the Q2 2021 unaudited condensed interim consolidated financial statements.
