TORONTO -- (Business Wire)

Sherritt International Corporation (“Sherritt” or the “Corporation”) (TSX:S) today announced its fourth quarter and full year 2025 production results. During the fourth quarter 2025, Sherritt received $7.7 million of dividends in Canada from Energas S.A. (“Energas”) bringing the total to $26.0 million for the year, double the $13.0 million received in 2024.

Dr. Peter Hancock, Interim Chief Executive Officer of Sherritt commented. “Since my appointment in December, I have worked with our joint venture partner on a comprehensive operational turnaround at Moa to address the challenges we saw in 2025 and support a return to consistent operational performance at the site. Our efforts aim to strengthen the productivity and reliability of the mine’s operations amid heightened geopolitical uncertainty and ultimately pave the way for us to realize the full benefit from our expansion. Our Power division demonstrates what focused operational improvements can achieve with our dividends doubling this year to $26 million. We will be applying the same operational discipline at Moa to replicate that success in the years ahead.”

2025 Production Results

Metals

Finished nickel and cobalt production were at the lower ends of their revised 2025 guidance ranges. In the fourth quarter 2025, continued lower-than-expected production of mixed sulphides at Moa impacted feed availability at the refinery. This was primarily due to below-plan mined ore volumes, lower leach train availability, a delay in commodity procurement, national grid power outages and periods of reduced operating rates following Hurricane Melissa. As well, Sherritt did not acquire additional third-party feed given high payabilities in the intermediate market. Full year 2025 net direct cash cost (“NDCC”)¹ was within the guidance range originally disclosed at the start of the year of US$5.75 to US$6.25 per pound of nickel sold benefiting from higher cobalt by-product credits from higher average-realized cobalt prices and ongoing cost optimization initiatives.

Power

Electricity production was slightly below the low end of its 2025 guidance range. While capable of producing more, during the fourth quarter 2025, the Varadero and Boca de Jaruco facilities were required by the government agency Unión Eléctrica (“UNE”) to operate in frequency control for periods to help stabilize the national power grid, thus restricting output. Energas was fully compensated for this reduction resulting in no impact to Power’s Adjusted EBITDA¹, earnings from operations or dividends from Energas to Sherritt in Canada during the year. Full year 2025 unit operating cost¹ was at the lower end of the 2025 guidance range of US$23.00 to US$24.50 per MWh.

Operational Update

In response to the operational challenges encountered at the Moa mine in 2025, coupled with heightened geopolitical uncertainty, Sherritt is collaborating with its joint venture partner to review the existing recovery plan and identify additional opportunities to improve the mine’s performance and reliability against a backdrop of ongoing adverse operating conditions.

The operational review will aim to stabilize the site and gradually restore production of mixed sulphides to pre-2025 levels. Following stabilization of the site, the ramp up of the Moa JV expansion program will be reassessed and optimized to realize the full benefit.

Sherritt is actively monitoring recent regional geopolitical developments and is working closely with its joint venture partner to anticipate and respond to potential risks. Sherritt has a track record of navigating complex operating environments throughout the 30-year history of the Moa Joint Venture.

Sherritt expects to provide a further operational update when it reports its financial results for the fourth quarter and year ended December 31, 2025 on February 10, 2026 after market close. The Corporation’s 2026 guidance for production, NDCC¹, unit operating costs¹, spending on capital¹ and estimated distributions under the Cobalt Swap agreement and dividends from Energas will also be provided. Guidance for Power electricity production will reflect the expected impact of the Varadero facility operating in frequency control which is expected for most of 2026.

Non-GAAP and Other Financial Measures

Adjusted EBITDA, 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 IFRS^® Accounting Standards measures, and do not have a standard definition under IFRS Accounting Standards and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS Accounting Standards. As these measures do not have a standardized meaning, they may not be comparable to similar measures provided by other companies.

For a complete discussion of Non-GAAP and other financial measures, including reconciliations to the most directly comparable IFRS Accounting Standards as presented in the financial statements, see the Corporation’s most recent Management’s Discussion and Analysis for the three months ended September 30, 2025 available on Sherritt’s website and SEDAR+.

Adjusted EBITDA

The Corporation defines Adjusted EBITDA as earnings/loss 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.

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.

Unit operating costs/Net direct cash cost

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 by-product and other revenue; cobalt gain/loss pursuant to the Cobalt Swap; realized gain/loss on natural gas swaps; royalties/territorial contributions; 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.

Unit operating costs for nickel and electricity are key measures that management and investors use to monitor cost performance. NDCC of nickel is a widely-used performance measure for nickel producers which represents the direct cash cost associated with the mining, processing, refining and sale of finished nickel, net of by-product credits. 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.

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 JV prior to payment and includes adjustments to accruals.
