Sherritt Reports Q1 Results and Successful Implementation of the Cobalt Swap

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE U.S.

Sherritt International Corp. ("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 months ended March 31, 2023. All amounts are in Canadian currency unless otherwise noted.

"We are pleased with our continued accomplishments in the first quarter of this year," said Leon Binedell, President and CEO of Sherritt International. "The effectiveness of the Cobalt Swap was proven with almost 75% of cobalt volume for the year received to date. We expect to receive the entire US$114 million through cobalt and cash distributions by mid-year, and all cash receipts from the sale of cobalt distributions to be received before the end of the year."

Mr. Binedell continued, "In addition, we published our NI 43-101 Technical Report for the Moa JV which more than doubles reserves and extends the life of mine to 26 years. This technical report underpins and validates our long-term strategy for producing low cost, high purity nickel and cobalt."

SELECTED Q1 2023 DEVELOPMENTS

• Net earnings from continuing operations was $13.6 million, or $0.03 per share in Q1 2023, compared to net earnings from continuing operation of $16.4 million, or $0.04 per share, in Q1 2022.
• Adjusted EBITDA⁽¹⁾ in the quarter was $40 million compared to $59 million in Q1 2022.
• In accordance with the Cobalt Swap:
  • The Moa JV distributed 1,280 tonnes (100% basis) of the 2,082 annual maximum volume (61%) of finished cobalt with an in-kind value of $58 million (100% basis);
  • GNC's 50% share of the distribution ($29 million) was redirected to Sherritt to settle the GNC receivable;
  • Sherritt sold 696 tonnes, $30 million, of cobalt to third parties during the quarter; and
  • Sherritt received $19 million in cash from the sale of cobalt.
• Filed a National Instrument 43-101 technical report for the Moa JV which indicates that current reserves estimates are sufficient to extend the life of mine to 2048 with an after-tax NPV (8%) of US$1.5 billion (100% basis) in the alternative case based on recent analyst nickel, cobalt and input commodity price forecasts.
• Sherritt's share of finished nickel and cobalt production at the Moa Joint Venture (Moa JV) was 3,483 tonnes and 367 tonnes, 10% and 18% lower, respectively, than the prior year quarter.
• Net direct cash cost (NDCC)⁽¹⁾ was US$6.46/lb in Q1 2023 compared to US$3.42/lb in Q1 2022 primarily due to materially lower realized cobalt prices, placing Sherritt in the second cost quartile for HPAL nickel producers.
• Power production increased 15% to 158 GWh compared to Q1 2022 as a result of additional gas supply.

DEVELOPMENTS SUBSEQUENT TO QUARTER END

• Successfully completed the drilling and testing of a new gas well for CUPET in the Puerto Escondido field in Cuba and commenced drilling on a second well. The additional gas will be provided to Energas for use in power production starting in Q2.
• In accordance with the Cobalt Swap, subsequent to quarter-end:
  • The Moa JV distributed an additional 240 tonnes of cobalt (100% basis) with an in-kind value of $9 million;
  • GNC's 50% share of the distribution ($5 million) was redirected to Sherritt to settle the GNC receivable;
  • Sherritt sold 152 tonnes, $7 million, of cobalt to third-parties; and
  • Sherritt received $13 million in cash from the sale of cobalt.

Q1 2023 FINANCIAL HIGHLIGHTS

Cash and cash equivalents as at March 31, 2023 were $138.3 million, up from $123.9 million at December 31, 2022. During Q1 2023, Sherritt received $18.8 million in cash from the sale of cobalt to third-parties (Cobalt Swap); generated $15.7 million from the Fort Site primarily due to strong fertilizer pre-sales, offset by a $24.4 million payment for share-based compensation. In addition, Energas paid $6 million (33?% basis) to GNC, in Cuban pesos, in accordance with the Cobalt Swap. During the quarter, Sherritt drew $18.0 million on its revolving credit facility.

Of the $138.3 million of cash and cash equivalents, $45.4 million was held in Canada, including cash received under the Cobalt Swap. The remaining amounts were held in Cuba and other countries.

Subsequent to the quarter-end, Sherritt paid $9.4 million in interest on its second lien notes. At the interest payment date, the Corporation was not required to make a mandatory redemption of second lien notes as it did not meet the minimum liquidity threshold as defined in the indenture agreement.

REVIEW OF OPERATIONS

Reportable segment update

As a result of the Cobalt Swap transaction, effective January 1, 2023, the former "Moa JV and Fort Site" reportable segment and the "Metals Other" reportable segment were combined into one new "Metals" segment, reflecting the Corporation's 50% interest in the operations of the Moa Joint Venture, its 100% interest in the utility and fertilizer operations (Fort Site), and the 100% interest in subsidiaries established to market and sell Moa Joint Venture's nickel and cobalt production and the Corporation's cobalt inventory received under the Cobalt Swap (Metals Marketing). Information for the prior period was restated for comparative purposes to reflect the new Metals reportable segment.

Metals

Metals revenue in Q1 2023 of $176.5 million was down 6% from $187.6 million in the same period last year. Approximately $15 million of cobalt revenue in Q1 2023 is attributable to the additional cobalt received and sold by Sherritt pursuant to the Cobalt Swap. Excluding the impact of the additional Cobalt Swap volume sold, total revenue was 14% lower primarily due to materially lower cobalt average-realized prices⁽¹⁾. Fertilizer revenue was 18% lower as a result of lower volume and average-realized price. Nickel revenue was relatively unchanged as the higher average-realized prices offset lower sales volume.

In Q1 2023 the average-realized prices for nickel and cobalt were $16.47/lb and $19.11/lb, 11% higher and 54% lower, respectively, compared to the same period in the prior year. Nickel sold at a slight premium to the reference price, while cobalt prices continued to reflect near-term softness in the market. Both nickel and cobalt average-realized prices benefited from a weaker Canadian dollar relative to the U.S. dollar.

Mixed sulphides production at the Moa JV in Q1 2023 was 3,750 tonnes, down 9% from the 4,126 tonnes produced in Q1 2022. The variance was primarily related to lower ore grade and unplanned leach train maintenance due to feed characteristics. As the Moa JV continues to advance mine development to new ore bodies in 2023, some of the operational challenges related to feed characteristics in Q1 will be reduced.

Sherritt's share of finished nickel and cobalt production in Q1 2023 totaled 3,483 tonnes and 367 tonnes, 10% and 18% lower than amounts produced in Q1 2022, respectively. Q1 2023 finished production was impacted by lower mixed sulphide feed availability at the refinery.

Fertilizer production for the three months ended March 31, 2023 was 8% lower compared to Q1 2022, in line with metals production.

NDCC⁽¹⁾ per pound of nickel sold increased to US$6.46/lb in Q1 2023 from US$3.42/lb in Q1 2022 placing Sherritt in the second cost quartile for HPAL nickel producers. The higher NDCC was primarily due to materially lower cobalt prices, higher MPR costs, and lower net fertilizer by-product credits. Higher MPR costs primarily relate to higher opening inventory costs, lower production volumes, and higher diesel prices. Input commodity prices were lower in Q1 2023 compared to Q4 2022 and are expected to remain lower than 2022 throughout the current year. The impact of the Cobalt Swap on NDCC was not significant.

Sustaining spending on capital⁽¹⁾ in Q1 2023 was $5.9 million, down by 62% from $15.7 million in Q1 2022 primarily due to timing of spending at both the Moa JV and Fort Site including the receipt of mining equipment in Moa in the prior year.

Growth spending on capital, which represents spending on the Joint Venture's expansion program, was $3.7 million, most of which was related to spending on the slurry preparation plant (SPP).

The increase in free cash flow⁽¹⁾ resulted in higher ending cash balances at the Moa JV in Q1 2023 as cash distributions to shareholders will not occur until the annual maximum cobalt volume distribution under the Cobalt Swap has been met. Cobalt Swap and normal course cash distributions are expected to commence mid-year 2023.

Moa JV expansion program update

Progress for the expansion program in Q1 2023 included:

Slurry Preparation Plant:

The SPP construction continues to progress and remains on budget and on time for expected completion in early 2024;

• structural steel is 80% erected and field assembly of major equipment is near completion with piping, electrical and instrumentation installation to commence in May; and
• the slurry and water return pipelines are 25% complete and are expected to be finished in Q4 2023.

Processing Plant:

The processing plant expansion is progressing on schedule for an expected year end-2024 completion;

• the Joint Venture received approval of the feasibility study from the Cuban authorities in Q1 for the Moa processing plant expansion;
• all significant contracts for long lead items for the Sixth Leach Train have been awarded or are in the process of being awarded and a detail project execution schedule is being finalized;
• engineering for the Fifth Sulphide Precipitation Train is ongoing and will be completed in Q2 2023; and
• preliminary engineering has been completed on the acid storage tanks and currently awaiting Cuban authorities' approval to construct.

Moa JV Life of mine/Updated NI 43-101 Technical Report

On March 31, 2023, Sherritt filed an updated National Instrument 43-101 Technical Report for the Moa Joint Venture indicating that current reserves are estimated to support a 26-year life of mine. Other highlights include:

• Proven and Probable reserves increased to 1,182 kt of nickel and 144 kt of cobalt, an increase of 110% and 129%, respectively;
• the life of mine extends to 2048, an increase of 14 years, with total estimated metal recovery of 724 kt of nickel and 85 kt of cobalt;
• over the next 10 years, average annual finished metal production of 30 kt of nickel and 3.3 kt of cobalt from Moa is expected, excluding the impact of the Moa JV expansion program and refining third-party feeds;
• favourable economics in the base case scenario supports an after-tax NPV (8%) of US$812 million (100% basis) using conservative prices of US$7.12/lb nickel and US$21.32/lb cobalt;
• significant upside in an alternative case increases the after-tax NPV (8%) to US$1.5 billion (100% basis) using recent analyst commodity price forecasts of US$9.00/lb nickel, US$23.50/lb cobalt and higher input commodity prices.
• NPV scenarios exclude the upside impact from the Moa JV expansion. Once completed by the end of 2024, the full expansion is expected to result in a higher NPV but shorten the life of mine by 3-5 years.

Power

Revenue for Q1 2023 of $10.3 million was 14% higher than Q1 2022 primarily due to higher production resulting in higher sales of 158 GWh compared to 137 GWh in the prior year period. Higher production was primarily due to greater equipment availability as a result of maintenance activities completed in the prior year. Q1 2023 revenue also benefited from higher average-realized price⁽¹⁾ due to the impact of a stronger U.S. dollar relative to the Canadian dollar compared to Q1 2022.

Unit operating costs⁽¹⁾ for the three months ended March 31, 2023 were $19.37/MWh, up 23%, from Q1 2022 primarily as a result of the timing of maintenance spending, partly offset by higher electricity production and sales volume. The Moa Swap has been beneficial in providing the Power business with the liquidity required to effectively manage maintenance spending and the operation of the business.

The Power business unit had $0.7 million spending on capital⁽¹⁾ in Q1 2023. Spending on capital is primarily driven by timing of maintenance activities.

Subsequent to the quarter end, Sherritt successfully completed the drilling and testing of a new gas well for CUPET in the Puerto Escondido field and commenced drilling on a second well. The additional gas will be provided to Energas for use in power production starting in Q2.

Technologies

During the three months ended March 31, 2023, Technologies continued to provide technical support, process optimization and technology development services to the Moa JV and the Fort Site and continued to support the Moa JV's expansion strategy. These activities included establishing an updated mineral reserves estimate and life of mine plan utilizing economic cut-off grade, finalizing the updated NI 43-101 Technical Report, supporting on-going process plant improvements and debottlenecking work at Moa and the Fort Site locations. Technologies also continued to progress on its commercialization activities around proprietary technologies and innovative industry solutions. As well in the quarter, Technologies:

• received a Natural Resources Canada (NRCan) funding commitment of $0.8 million to evaluate the possibility of using mixed hydroxide precipitate (MHP) as an additional feed material for producing high purity nickel and cobalt metals at the Fort Saskatchewan refinery;
• signed an agreement with Aurora Hydrogen to support the development of turquoise hydrogen production technology, including Aurora building a demonstration plant at the Sherritt Technologies facility. Hydrogen gas is used as a reagent at Sherritt's refinery; and
• signed an agreement with a major mining company to conduct batch testing on specific laterite opportunities to test applicability of Sherritt's next generation laterite (NGL) technology and advanced a proposal on the potential to jointly develop the technology.

For descriptions of ongoing commercialization projects, see the Corporation's MD&A for the year ended December 31, 2022 available on Sherritt's website of on SEDAR.com.

OUTLOOK

2023 guidance for production volumes, unit operating costs and spending on capital remains unchanged. Sherritt continues to monitor the volatility in cobalt prices. NDCC guidance is based on a US$23.50/lb cobalt reference price. If the Q1 2023 average reference price of US$17.56/lb were to persist through the remainder of the year, NDCC guidance could increase by approximately US$0.85/lb, assuming all other assumptions remain constant.

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 condensed consolidated financial statements for the three months ended March 31, 2023.

Combined revenue

The Corporation uses combined revenue as a measure to help management assess the Corporation's financial performance across its operations. Combined revenue includes the Corporation's consolidated revenue and revenue of the Moa JV on a 50% basis, which is accounted for using the equity method for accounting 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 earnings (loss) from operations and joint venture, which excludes net finance 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.

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 earnings (loss) 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 division. The average-realized price for power excludes by-product 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.

The tables below reconcile revenue per the financial statements to average-realized price:

Unit operating cost/NDCC

With the exception of Metals, which uses NDCC, unit operating cost is generally calculated by dividing cost of sales as reported in the financial statements, less depreciation, depletion and amortization in cost of sales, the impact of impairment losses, gains and losses on disposal of property, plant, and equipment and exploration and evaluation assets and certain other non-production related costs, by the number of units sold.

Metals' NDCC is calculated by dividing cost of sales, as reported in the financial statements, adjusted for the following: depreciation, depletion, amortization and impairment losses in cost of sales; cobalt by-product, fertilizer and other revenue; cobalt gain/loss; and other costs primarily related to the impact of opening and closing inventory values, by the number of finished nickel pounds sold in the period, expressed in U.S. dollars.

Unit operating costs for nickel and electricity are key measures that management and investors uses to monitor performance. NDCC of nickel is a widely-used performance measure for nickel producers. Management uses unit operating costs/NDCC to assess how well the Corporation's producing mine and power facilities are performing and to assess overall production efficiency and effectiveness internally across periods and compared to its competitors.

Unit operating cost (NDCC) for nickel is expressed in U.S. dollars per pound sold, while electricity is expressed in Canadian dollars per megawatt hour sold.

The tables below reconcile cost of sales per the financial statements to unit operating cost/NDCC:

Adjusted net earnings/loss from continuing operations and adjusted net earnings/loss from continuing operations per share

The Corporation defines adjusted net earnings/loss from continuing operations as net earnings/loss from continuing operations less items not reflective of operational performance. These adjusting items include, but are not limited to, inventory obsolescence, impairment of assets, gains and losses on the acquisition or disposal of assets, unrealized foreign exchange gains and losses, gains and losses on financial assets and liabilities and other one-time adjustments. While some adjustments are recurring (such as unrealized foreign exchange (gain) loss and revaluations of allowances for expected credit losses (ACL)), management believes that they do not reflect the Corporation's operational performance or future operational performance. Adjusted net earnings/loss from continuing operations per share is defined consistent with the definition above and divided by the Corporation's weighted-average number of common shares outstanding.

Management uses these measures internally and believes that they provide investors with performance measures with which to assess the Corporation's core operations by adjusting for items or transactions that are not reflective of its core operating activities.

The table below reconcile net earnings (loss) from continuing operations and net earnings (loss) from continuing operations per share, both per the financial statements, to adjusted net earnings (loss) from continuing operations and adjusted net earnings (loss) from continuing operations per share, respectively:

Spending on capital

The Corporation defines spending on capital for each segment as property, plant and equipment and intangible asset expenditures on a cash basis adjusted to the accrual basis in order to account for assets that are available for use by the Corporation and the Moa Joint Venture prior to payment and includes adjustments to accruals. The Moa Joint Venture and Fort Site segment's spending on capital includes the Fort Site's expenditures, plus the Corporation's 50% share of the Moa Joint Venture's expenditures, which is accounted for using the equity method for accounting purposes.

Combined spending on capital is the aggregate of each segment's spending on capital or the Corporation's consolidated property, plant and equipment and intangible asset expenditures and the property, plant and equipment and intangible asset expenditures of the Moa Joint Venture on a 50% basis, all adjusted to the accrual basis.

Combined spending on capital is used by management, and management believes this information is used by investors, to analyze the Corporation and the Moa Joint Venture's investments in non-current assets that are held for use in the production of nickel, cobalt, fertilizers, oil and gas and power generation.

The tables below reconcile property, plant and equipment and intangible asset expenditures per the financial statements to combined spending on capital, expressed in Canadian dollars:

Combined free cash flow

The Corporation defines free cash flow for each segment as cash provided (used) by continuing operations for operating activities, less cash expenditures on property, plant and equipment and intangible assets, including exploration and evaluation assets. The Metals segment's free cash flow includes the Fort Site and Metals Marketing's free cash flow, plus the Corporation's 50% share of the Moa JV's free cash flow, which is accounted for using the equity method for accounting purposes. The Corporate segment's cash used by continuing operations for operating activities is adjusted to exclude distributions received from Moa JV.

Combined free cash flow is the aggregate of each segment's free cash flow or the Corporation's consolidated cash provided (used) by continuing operations for operating activities, less consolidated cash expenditures on property, plant and equipment and intangible assets, including exploration and evaluation assets, less distributions received from Moa JV, plus cash provided (used) by continuing operations for operating activities for the Corporation's 50% share of the Moa JV, less cash expenditures on property, plant and equipment and intangible assets for the Corporation's 50% share of the Moa JV. Distributions from the Moa JV excluded from Corporate cash used by continuing operations for operating activities are included in the Adjustment for Moa Joint Venture to arrive at total cash provided (used) by continuing operations for operating activities per the financial statements.

Free cash flow is used by management, and management believes this information is used by investors, to analyze cash flows generated from operations and assess its operations' ability to provide cash or its use of cash, after funding cash capital requirements, to service current and future working capital needs and service debt.
