Sherritt Announces Cost-Cutting Initiatives and Changes to Executive Management, Reports 2023 Production Results

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

Sherritt International Corp. ("Sherritt" or the "Corporation") (TSX:S) today announced that in line with the Corporation's ongoing commitment to cost optimization, the need to improve operations and in response to market conditions, a number of organization-wide cost cutting initiatives and changes to its executive management have been completed resulting in a more cost efficient and adaptable organization anchored in delivering value through its core businesses while retaining expertise and capabilities to pursue future growth opportunities spurred by the energy transition. Further, Sherritt provided an update on its fourth quarter and full year 2023 production results and its expansion program at the Moa Joint Venture (Moa JV).

Corporate Restructuring

During the second half of 2023, the Corporation conducted an in-depth internal review which identified its Metals and Technologies divisions as primary opportunities to optimize through restructuring. Metals has been streamlined to deliver value in the near-term while ensuring safe and effective operations. Technologies has been restructured to a reduced scale in line with a narrower focus to deliver essential support and enhancements to internal operations and business development. Business development will primarily focus on near-term partnerships and development opportunities to expand midstream processing capacity of critical minerals for the electric vehicle supply chain which Sherritt has been working to advance given its differentiated and specialized technical expertise in hydrometallurgical processing. As a result of the changes made, the workforce across the Corporation's Canadian operations is being reduced by approximately 10%, with annual employee cost savings of $13 million expected to be realized.

To align with this restructuring, the Corporation is announcing changes to its executive management team to consolidate operational leadership with the appointment of Elvin Saruk as Chief Operating Officer, responsible for leading both Sherritt's Metals and its Power and Oil and Gas divisions. Mr. Saruk has more than 30 years of experience with Sherritt including at the senior executive level managing large-scale operations, overseeing complex high pressure acid leach (HPAL) mining and processing projects and strengthening partner relations while overseeing operations in Cuba. Prior to this appointment, Mr. Saruk was Senior Vice-President, Oil and Gas and Power and Head of Growth Projects, most recently responsible for leading the Moa Joint Venture's expansion program and growing production at the Corporation's Power division during 2023. Along with this change, Dan Rusnell Senior Vice President, Metals has left the organization.

"We would like to thank Dan for his years of service and valuable contributions to Sherritt. We wish him the very best in the future," said Leon Binedell, President and CEO of Sherritt.

Mr. Binedell continued, "Our comprehensive, organization-wide restructuring and cost-cutting program is the outcome of a robust internal assessment and a necessary endeavour to improve Metals operations following a disappointing 2023 and reduce non-essential expenditures in the currently depressed metal price environment which Sherritt has extensive experience navigating. As a result of our cost-cutting program, we have had to make the difficult decision to reduce headcount across the organization and we would like to express our sincere gratitude to all affected employees for their dedication and the contributions they have made."

Mr. Binedell added, "We are pleased to announce Elvin's appointment as Chief Operating Officer, expanding his responsibilities and building off the momentum he has achieved in successfully advancing the Moa Joint Venture's expansion program and significantly increasing electricity production in our Power division. We look forward to the value Elvin will deliver in his expanded role.

Today's announcement reflects our objectives to respond to market realities and proactively pursue opportunities, including optimizing costs, improving profitability and liquidity and growth opportunities to enhance and diversify our business."

2023 Production Results

Metals

Full year 2023 finished nickel and finished cobalt production were slightly below their respective revised annual guidance ranges as a result of fourth quarter production being impacted by lower availability of Moa mixed sulphides due to heavier than normal rainfalls requiring processing of lower grade and quality stockpiled materials. Full year 2023 Metals net direct cash costs (NDCC)¹ per pound of nickel sold are expected to be within the previously disclosed guidance range.

Power

Full year 2023 electricity production exceeded revised guidance. Unit operating costs¹ are expected to be within the previously disclosed guidance range.

Sherritt expects to report its full operational and financial results for the fourth quarter and year ended December 31, 2023 on February 7, 2024 after market close. The Corporation's 2024 guidance for production, NDCC, unit operating costs¹ and spending on capital¹ will also be provided with year-end 2023 results and will incorporate the restructuring changes to the Corporation outlined above.

Expansion Advancing on Budget and on Schedule

Sherritt's low cost and low capital intensity two-phase Moa JV expansion program remains on budget and on schedule. The Slurry Preparation Plant (SPP) is mechanically complete and pre-commissioning is ongoing with ore feed to the plant expected to commence later in January. Phase one of the expansion is expected to reduce ore haulage distances, lower carbon intensity from mining and increase annual mixed sulphide precipitate (MSP) production of contained nickel and cobalt through increased throughput over the mine's long life. With the completion of phase two of the Moa expansion, annual MSP production is targeted to increase by 6,500 tonnes of contained nickel and cobalt (100% basis) 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.

¹ Non-GAAP and Other Financial Measures

Unit operating cost/net direct cash cost (NDCC) and spending on capital are non-GAAP financial measures. Management uses these measures to monitor the financial performance of the Metals, Power and other operating divisions. Management 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 operations. These measures are intended to provide additional information, not to replace International Financial Reporting Standards (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.

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 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 JV prior to payment and includes adjustments to accruals.
