Sherritt Reports Second Quarter 2024 Results; Metals and Power Deliver Strong Performance; Net Direct Cash Cost Significantly Improved

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Sherritt International Corporation ("Sherritt", the "Corporation") (TSX: S), a world leader in using hydrometallurgical processes to mine and refine nickel and cobalt metals deemed critical for the energy transition today reported its financial results for the three and six months ended June 30, 2024. All amounts are in Canadian dollars unless otherwise noted.

Leon Binedell, President and CEO of Sherritt commented, "We are encouraged by the strong operational turnaround and improved performance delivered by both our Metals and Power businesses in line with our plans developed last year in response to the market decline and operational challenges experienced. At Metals, nickel, cobalt and fertilizer production benefitted from improved operating reliability and increased mixed sulphides availability as we begin to see the positive impacts of the slurry preparation plant commissioned earlier this year. Notably, our net direct cash cost of US$5.75 per pound was a significant improvement and with our continued focus on operating stability, margin improvement and cash generation, we see the potential to realize further cost improvements ahead. At Power, we continue to achieve increased production and improved utilization. We are pleased to announce an additional well is scheduled to be drilled this year which will increase our output further. The additional supply of gas in Power has resulted in a materially higher dividend of $5.1 million received in Canada this quarter and we expect to continue receiving higher dividends going forward."

Mr. Binedell continued, "With nickel and cobalt both facing headwinds and prices considered at or near the bottom, our lower operating costs and the advancements in operational improvements we have made, place us in a strong position to weather these near-term market uncertainties unlike many non-Chinese linked suppliers which have already announced their exit from the market. Once these near-term market uncertainties abate, we will ultimately capitalize on the future growth opportunities ahead with strong demand expected over the medium-term for the responsibly sourced critical minerals we produce."

SECOND QUARTER 2024 SELECTED DEVELOPMENTS

• Sherritt's share ⁽¹⁾ of finished nickel and cobalt production at the Moa Joint Venture ("Moa JV") was 3,383 tonnes and 342 tonnes, respectively.
• Sherritt's share of finished nickel and cobalt sales was 3,791 tonnes and 390 tonnes, respectively. Nickel sales volumes exceeded production volumes on continued strong spot sales which are expected to continue in the second half of the year, driving progress on reducing nickel inventory.
• Net direct cash cost ("NDCC") ⁽²⁾ was US$5.75/lb benefitting from lower mining, processing and refining costs per pound of nickel sold ("MPR/lb"), the largest component of NDCC ⁽²⁾ , which improved 15% compared to Q2 2023. Compared to Q1 2024, NDCC ⁽²⁾ continued to improve as expected decreasing by 21%.
• Received $5.1 million of dividends in Canada from Energas during the quarter. Based on current 2024 guidance estimates for production volumes, unit operating costs ⁽²⁾ and spending on capital ⁽²⁾ disclosed in the Outlook section of the MD&A, Sherritt expects total dividends in Canada from Energas to exceed $10.0 million in 2024 ⁽³⁾ .
• Electricity production was 205 GWh benefitting from increased gas supply from the two wells that went into production at the end of Q2 2023.
• Electricity unit operating cost ⁽²⁾ was $42.74/MWh reflecting timing of higher scheduled maintenance, partly offset by higher sales volume.
• 2024 guidance for production volumes, unit operating costs/NDCC ⁽¹⁾ and spending on capital ⁽¹⁾ remain unchanged.
• Net loss from continuing operations was $11.5 million, or $(0.03) per share primarily due to lower average-realized prices ⁽²⁾ for nickel, cobalt and fertilizers, partly offset by higher nickel sales volumes.
• Adjusted net loss from continuing operations ⁽²⁾ was $10.0 million or $(0.03) per share, which primarily excludes a non-cash $5.3 million revaluation loss on the net receivable pursuant to the Cobalt Swap ⁽⁴⁾ on updates to valuation assumptions and a $3.4 million unrealized gain on nickel put options.
• Adjusted EBITDA ⁽²⁾ was $13.0 million.
• Available liquidity in Canada as at June 30, 2024 was $55.9 million supported by $27.0 million received from the Moa JV as full repayment of short-term working capital advances primarily offset by $7.8 million used for operating activities at Power to support scheduled maintenance activities, a $9.4 million interest payment on Second Lien Notes and a $10.8 million payment on rehabilitation and closure costs related to legacy Oil and Gas assets in Spain.
• Sherritt's syndicated revolving-term credit facility was amended to extend its maturity by one year from April 30, 2025 to April 30, 2026 and change the EBITDA-to-Interest Expense covenant as defined in the agreement. There were no other significant changes to the terms, financial covenants or restrictions.
• Purchased put options on 3,876 tonnes of nickel, or 646 tonnes per month, at an exercise price of US$8.16/lb at a cost of $2.2 million for a six-month period starting from June 1, 2024. Any settlements will be paid in cash monthly based on the average monthly nickel price on the London Metal Exchange ("LME"). The economic hedging strategy provides Sherritt with full exposure to upward changes in nickel prices, while protecting against downward changes in nickel prices by providing a minimum price of US$8.16/lb on approximately 25% of expected nickel production from the Moa JV during the six-month period. In July, Sherritt received $0.4 million upon settlement of the June 2024 in-the-money put option.
• Opportunistically repurchased $1.5 million of 10.75% unsecured PIK option notes ("PIK Notes") at a 50% discount.
• Released the Corporation's 2023 Sustainability Report marking the 16th year of sustainability reporting and outlining significant progress made during the year toward its ESG goals and highlighting achievements made during the year including maintaining conformity with the LME's Track B Responsible Sourcing Requirements.
• Completed a 10% workforce reduction at its Corporate office in Q2 2024 in addition to the Canada-wide restructuring completed in Q1 2024. Annual cost savings from these cumulative employee and other cost reductions are expected to be $15.0 million per year.
• Phase two of the Moa JV expansion continues with commissioning and ramp up expected in the first half of 2025.
• Advanced the mixed hydroxide precipitate processing project ("MHP Project") with the commencement of an engineering study and continued batch test work and process flowsheet development, which yielded very positive results for metal recoveries and impurity removals.

DEVELOPMENTS SUBSEQUENT TO THE QUARTER

Subsequent to the quarter end:

• The Moa JV received approval for US$12 million of foreign currency financing from a Cuban bank to support international payments related to construction of the Sixth Leach Train, the primary component of phase two of the expansion project.
• Elected not to pay cash interest due July 2024 of $3.5 million and added the payment-in-kind interest to the principal amount owed to noteholders on its 10.75% unsecured PIK notes.

Q2 2024 FINANCIAL HIGHLIGHTS

Cash and cash equivalents as at June 30, 2024 were $132.3 million, decreasing from $144.4 million as at March 31, 2024.

As at June 30, 2024, total available liquidity in Canada, which is composed of cash and cash equivalents in Canada of $25.5 million and available credit facilities of $30.4 million was $55.9 million decreasing from $67.9 million as at March 31, 2024 as expected. Available liquidity in Canada during the quarter was supported by $27.0 million received from the Moa JV as full repayment of short-term working capital advances, and $5.1 million of dividends from Energas received in Canada. These receipts were primarily offset by $7.8 million used for operating activities at Power primarily to support scheduled maintenance activities, a $9.4 million interest payment on Second Lien Notes and a $10.8 million payment on rehabilitation and closure costs related to legacy Oil and Gas assets in Spain. The receipt of the Moa JV advance repayment is reflected in cash provided by investing activities.

Moa JV's cash and cobalt distributions to the Corporation are determined based on available cash in excess of liquidity requirements. Determinants of liquidity include anticipated nickel and cobalt prices, planned spending on capital at the Moa JV including growth capital, working capital needs, expected financing and other expected liquidity requirements. Available cash is also impacted by changes in working capital primarily related to changes in inventory, and timing of receipts and payments, including receipts on nickel and cobalt sales subsequent to shipment. Based on the midpoint of the Moa JV's 2024 guidance ranges for production volumes, unit operating costs ⁽¹⁾ and spending on capital ⁽¹⁾ disclosed in the Outlook section of the MD&A, and the first half 2024 nickel and cobalt average reference prices of US$8.00/lb and US$13.50/lb, respectively, Sherritt expects to receive approximately $50.0 million in Cobalt Swap distributions (including both Sherritt's share and GNC's redirected share). As defined by the agreement, any short fall in the annual minimum payment amount will be added to the following year. With the full repayment of the short-term working capital advances to the Moa JV received in the second quarter of 2024, Sherritt expects the joint venture will commence dividends pursuant to the Cobalt Swap during the fourth quarter of 2024. Refer to the risks related to Sherritt's corporate structure in the Corporation's 2023 Annual Information Form for further information on risks related to distributions from the Moa JV.

In Power, based on 2024 guidance estimates for production volumes, unit operating costs ⁽¹⁾ and spending on capital ⁽¹⁾ disclosed in the Outlook section of the MD&A, Sherritt expects total dividends in Canada from Energas to exceed $10.0 million in 2024. Refer to the risks related to Sherritt's corporate structure in the Corporation's 2023 Annual Information Form for further information on risks related to dividends in Canada from Energas.

During the quarter, Sherritt purchased put options on 3,876 tonnes of nickel, or 646 tonnes per month, at an exercise price of US$8.16/lb at a cost of $2.2 million for a six-month period starting from June 1, 2024. Any settlements will be paid in cash monthly based on the average monthly nickel price on the LME. The economic hedging strategy provides Sherritt with full exposure to upward changes in nickel prices, while protecting against downward changes in nickel prices by providing a minimum price of US$8.16/lb on approximately 25% of expected nickel production from the Moa JV during the six-month period. In July, Sherritt received $0.4 million upon settlement of the June 2024 in-the-money put option.

Sherritt's syndicated revolving-term credit facility was amended to extend its maturity by one year from April 30, 2025 to April 30, 2026 and change the EBITDA-to-Interest Expense covenant as defined in the agreement. The amendment included terms to transition the interest rate of bankers' acceptance plus 4.00% to CORRA plus 4.00%. There were no other significant changes to the terms, financial covenants or restrictions.

At the Second Lien Note interest payment date in April 2024, the Corporation was not required to make a mandatory redemption of Second Lien Notes as it did not have Excess Cash Flow as defined in the Second Lien Notes indenture agreement for the two-quarter period ended December 31, 2023. Additionally, for the two-quarter period ended June 30, 2024, the Corporation did not have Excess Cash Flow as defined in the Second Lien Notes indenture agreement and, therefore, will not be required to make a mandatory redemption with its October 2024 interest payment.

As at June 30, 2024, the Corporation was in compliance with all its debt covenants.

Subsequent to the quarter end:

• The Moa JV received approval for US$12 million of foreign currency financing from a Cuban bank to support international payments related to construction of the Sixth Leach Train, the primary component of phase two of the expansion project.
• Elected not to pay cash interest due July 2024 of $3.5 million and added the payment-in-kind interest to the principal amount owed to noteholders on its PIK notes.

REVIEW OF OPERATIONS

Metals

Revenue

Metals revenue in Q2 2024 was $150.6 million compared to $185.6 million in Q2 2023. Revenue in the current year period was lower primarily due to lower average-realized prices ⁽¹⁾ for nickel, cobalt and fertilizer and the timing of receipts and sales of cobalt by Sherritt under the Cobalt Swap agreement, partly offset by higher nickel sales volumes. In Q2 2024 the average-realized prices ⁽¹⁾ for nickel, cobalt and fertilizers were $11.25/lb, $14.32/lb and $574.70/tonne, 17%, 12% and 19% lower, respectively, compared to the same period in the prior year.

Nickel revenue in Q2 2024 was $94.0 million compared to $95.5 million in Q2 2023. Finished nickel sales volumes in Q2 2024 were 19% higher than Q2 2023 and exceeded production volumes as Metals continued reducing its inventory with strong spot sales which are expected to continue in the second half of the year, driving progress on reducing nickel inventory.

Cobalt revenue in Q2 2024 was $12.3 million compared to $38.4 million in Q2 2023. Lower revenue was primarily due to the timing of receipts and sales of cobalt under the Cobalt Swap and lower average-realized prices ⁽¹⁾ . For more information regarding the timing of Cobalt Swap distributions in 2024, refer to the Cobalt Swap sales section below.

Fertilizer revenue in Q2 2024 was $34.8 million compared to $45.0 million in Q2 2023. In addition to lower average-realized prices ⁽¹⁾ , sales volumes for Q2 2024 were 4% lower compared to Q2 2023.

Cobalt Swap sales

For 2024, Cobalt Swap distributions are anticipated to start in the fourth quarter of the year whereas in 2023, Sherritt had received 100% of the annual maximum amount of cobalt (2,082 tonnes) and had sold approximately 85% of that cobalt by the end the first half of the year.

While the timing of receipts and sales of cobalt under the Cobalt Swap results in variances in cobalt sales volumes, revenue and cost of sales for Sherritt, they do not have a material impact on earnings from operations, average-realized prices ⁽¹⁾ , cobalt by-product credits, or NDCC ⁽¹⁾ as the variance in revenue and costs of Sherritt's share of cobalt under the Cobalt Swap is offset by Sherritt's share of revenue and costs of the Moa JV and the cost of cobalt sold on volumes of cobalt redirected from GNC ⁽²⁾ is determined based on the in-kind value of cobalt calculated as the cobalt reference price from the month preceding distribution less a mutually agreed selling cost adjustment.

Moa JV's cash and cobalt distributions to the Corporation are determined based on available cash in excess of liquidity requirements. Determinants of liquidity include anticipated nickel and cobalt prices, planned spending on capital at the Moa JV including growth capital, working capital needs, expected financing and other expected liquidity requirements. Available cash is also impacted by changes in working capital primarily related to changes in inventory, and timing of receipts and payments, including receipts on nickel and cobalt sales subsequent to shipment. Based on the midpoint of the Moa JV's 2024 guidance ranges for production volumes, unit operating costs ⁽¹⁾ and spending on capital ⁽¹⁾ disclosed in the Outlook section of the MD&A, and the first half 2024 nickel and cobalt average reference prices of US$8.00/lb and US$13.50/lb, respectively, Sherritt expects to receive approximately $50 million in Cobalt Swap distributions (including both Sherritt's share and GNC's redirected share). As defined by the agreement, any short fall in the annual minimum payment amount will be added to the following year. With the full repayment of the short-term working capital advances to the Moa JV received in the second quarter of 2024, Sherritt expects the joint venture will commence dividends pursuant to the Cobalt Swap during the fourth quarter of 2024. Refer to the risks related to Sherritt's corporate structure in the Corporation's 2023 Annual Information Form for further information on risks related to distributions from the Moa JV.

Production

Mixed sulphides production at the Moa JV in Q2 2024 was 4,095 tonnes, up 8% from the Q2 2023 primarily due to lower unplanned maintenance and improved ore quality being fed to the processing plant following the completion of the new Slurry Preparation Plant ("SPP") in Q1 2024.

During the second quarter of 2024, the annual refinery maintenance shutdown occurred and has been factored into the Corporation's 2024 guidance with higher production expected in the second half of the year. The planned annual maintenance shutdown also took place during the second quarter in 2023.

Sherritt's share of finished nickel and cobalt production in Q2 2024 was 3,383 tonnes and 342 tonnes, each 4% and 3% higher, respectively, than Q2 2023, primarily as a result of improved mixed sulphides availability.

Fertilizer production in Q2 2024 of 60,355 tonnes was 16% higher compared to Q2 2023 in line with higher nickel production, implementation of operational improvements, and due to the unplanned ammonia plant maintenance that occurred in the prior year period.

NDCC ⁽¹⁾

NDCC ⁽¹⁾ per pound of nickel sold was US$5.75/lb in Q2 2024 compared to US$7.22/in Q2 2023. NDCC ⁽¹⁾ significantly improved as expected, primarily as a result of lower MPR/lb and lower third-party feed costs partly offset by lower cobalt and net fertilizer by-product credits ⁽³⁾ . MPR/lb was 15% lower in Q2 2024 compared to Q2 2023 primarily due to lower sulphur and natural gas prices, lower purchased sulphuric acid, lower maintenance costs and the impact of higher nickel production and sales volumes. In Q2 2024 lower average-realized prices ⁽¹⁾ and sales volumes for cobalt and fertilizers resulted in lower by-product credits.

Compared to Q1 2024, NDCC ⁽¹⁾ continued to improve as expected decreasing by 21%. Sherritt maintains its 2024 guidance range for NDCC ⁽¹⁾ at US$5.50 to US$6.00/lb.

Spending on capital ⁽¹⁾

Sustaining spending on capital in Q2 2024 was $7.4 million compared to $13.6 million in Q2 2023. Sustaining spending on capital is lower as a result of timing of spending and consistent with lower annual guidance.

With the SPP completed and operating during Q1, growth spending on capital in Q2 2024 of $0.4 million was primarily related to spending on the second phase of the Moa JV expansion program.

Expansion program and strategic developments

Moa JV expansion program update

Phase two of the Moa JV's expansion program, the Processing Plant, is continuing to advance. During the second quarter of 2024 civil construction and structural erection was completed and piping installation commenced.

Subsequent to the end of the second quarter of 2024, the Moa JV received approval for US$12 million of foreign currency financing from a Cuban bank to support international payments related to construction of the Sixth Leach Train, the primary component of phase two of the expansion project.

Phase two commissioning and ramp up remains scheduled for 2025 with Sherritt expecting to commence the ramp up during the first half of the year. With completion of phase two, annual mixed sulphide precipitate production is expected to further increase toward the combined expansion target, including the new SPP, of approximately 20% of contained nickel and cobalt and is expected to fill the refinery to nameplate capacity to maximize profitability from the joint venture's own mine feed, displacing lower margin third-party feeds and increasing overall finished nickel and cobalt production.

Strategic developments

Sherritt, through its MHP Project, is advancing a flowsheet to produce high-purity nickel and cobalt sulphates and reduce sodium sulphate effluent, a key environmental challenge for the downstream industry. The MHP Project provides a strategic opportunity to expand Sherritt's current business into the production of nickel and cobalt sulphates, a key intermediary product required in the electric vehicle battery supply chain, where a current significant gap exists in North America. Sherritt's technical expertise and innovative processing solutions are key differentiators and enablers towards the Corporation's near-term strategic focus to expand its midstream processing capacity of critical minerals to fill this gap in North America in line with governments' objectives and incentives.

During the quarter, Sherritt commenced an engineering study and continued batch test work and process flowsheet development, which yielded very positive results for metal recoveries and impurity removals. A small scale continuous solvent extraction ("SX") pilot is planned for H2 2024 and process development work is expected to be completed by year end. Sherritt also continued its external engagement with governments and potential customers and funding partners, with a goal to reach agreement on key commercial and project parameters, including site identification, by year end.

Power

Revenue in Q2 2024 was $11.8 million, up 8% compared to Q2 2023, primarily due to higher production. The increase in electricity production is a result of additional gas from two wells that went into production at the end of Q2 2023.

As a key partner in supporting the Cuban government's plans to increase power production, Sherritt continues to work with its Cuban partners to increase gas supply and an additional well is scheduled to be drilled in the third quarter which is expected to provide additional electricity production in the second half of the year.

Unit operating costs ⁽¹⁾ in Q2 2024 were $42.74/MWh compared to $34.13/MWh in Q2 2023 primarily driven by the timing of scheduled maintenance activities which were completed in Q2 2024, partly offset by higher sales volumes.

Spending on capital ⁽¹⁾ in Q2 2023 was $1.5 million primarily driven by maintenance activities.

Sherritt received $5.1 million of dividends in Canada from Energas during the quarter. Based on 2024 guidance estimates for production volumes, unit operating costs ⁽¹⁾ and spending on capital ⁽¹⁾ disclosed in the Outlook section of the MD&A, Sherritt expects total dividends in Canada from Energas to exceed $10.0 million in 2024. Refer to the risks related to Sherritt's corporate structure in the Corporation's 2023 Annual Information Form for further information on risks related to dividends in Canada from Energas.

OUTLOOK

2024 guidance for production volumes, unit operating costs and spending on capital remains unchanged.

APPENDIX – NON-GAAP AND OTHER FINANCIAL MEASURES

Management uses the measures below to monitor the financial performance of the Corporation and its operating divisions and believes these measures enable investors and analysts to compare the Corporation's financial performance with its competitors and/or evaluate the results of its underlying business. These measures are intended to provide additional information, not to replace IFRS measures, and do not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As these measures do not have a standardized meaning, they may not be comparable to similar measures provided by other companies.

The non-GAAP and other financial measures are reconciled to the most directly comparable IFRS measure as presented in the consolidated financial statements for the three and six months ended June 30, 2024.

Combined revenue

The Corporation uses combined revenue as a measure to help management assess the Corporation's financial performance across its core operations. Combined revenue includes the Corporation's consolidated revenue, less Oil and Gas revenue, and includes the revenue of the Moa JV within the Metals reportable segment on a 50% basis. Revenue of the Moa JV is included in share of earnings of Moa Joint Venture, net of tax, as a result of the equity method of accounting and excluded from the Corporation's consolidated revenue.

Revenue at Oil and Gas is excluded from Combined revenue as the segment is not currently exploring for or producing oil and gas and its financial results relate to ancillary drilling services, provided to a customer and CUPET, and environmental rehabilitation costs for legacy assets, which are not reflective of the Corporation's core operating activities or revenue generation potential. The exclusion of revenue at Oil and Gas from Combined revenue represented a change in the composition of Combined revenue during the three months ended December 31, 2023 to better reflect the Corporation's core operating activities and revenue generation potential and the prior year measure has been restated for comparative purposes.

Management uses this measure to reflect the Corporation's economic interest in its operations prior to the application of equity accounting to help allocate financial resources and provide investors with information that it believes is useful in understanding the scope of Sherritt's business, based on its economic interest, irrespective of the accounting treatment.

The table below reconciles combined revenue to revenue per the financial statements:

Adjusted EBITDA

The Corporation defines Adjusted EBITDA as (loss) earnings from operations and joint venture, which excludes net finance expense, income tax expense and loss from discontinued operations, net of tax, as reported in the financial statements for the period, adjusted for: depletion, depreciation and amortization; impairment losses on non-current non-financial assets and investments; and gains or losses on disposal of property, plant and equipment of the Corporation and the Moa JV. The exclusion of impairment losses eliminates the non-cash impact of the losses.

Earnings/loss from operations at Oil and Gas (net of depletion, depreciation and amortization, if applicable) is deducted from/added back to Adjusted EBITDA as the segment is not currently exploring for or producing oil and gas and its financial results relate to ancillary drilling services, provided to a customer and CUPET, and environmental rehabilitation costs for legacy assets, which are not reflective of the Corporation's core operating activities or cash generation potential. The adjustment for earnings/loss from operations at Oil and Gas (net of depletion, depreciation and amortization, if applicable) represented a change in the composition of Adjusted EBITDA during the three months ended December 31, 2023 to better reflect the Corporation's core operating activities and cash generation potential and the prior year measure has been restated for comparative purposes.

Management uses Adjusted EBITDA internally to evaluate the cash generation potential of Sherritt's operating divisions on a combined and segment basis as an indicator of ability to fund working capital needs, meet covenant obligations, service debt and fund capital expenditures, as well as provide a level of comparability to similar entities. Management believes that Adjusted EBITDA provides useful information to investors in evaluating the Corporation's operating results in the same manner as management and the Board of Directors.

The tables below reconcile (loss) earnings from operations and joint venture per the financial statements to Adjusted EBITDA:

Average-realized price

Average-realized price is generally calculated by dividing revenue by sales volume for the given product in a given segment. The average-realized price for power excludes by-product and other revenue, as this revenue is not earned directly for power generation. Transactions by a Moa JV marketing company, included in other revenue, are excluded.

Management uses this measure, and believes investors use this measure, to compare the relationship between the revenue per unit and direct costs on a per unit basis in each reporting period for nickel, cobalt, fertilizer and power and provide comparability with other similar external operations.

Average-realized price for fertilizer is the weighted-average realized price of ammonia and various ammonium sulphate products.

Average-realized price for nickel and cobalt are expressed in Canadian dollars per pound sold, while fertilizer is expressed in Canadian dollars per tonne sold and electricity is expressed in Canadian dollars per megawatt hour sold.
