(1)  Non-GAAP financial measures. Q1 2025 actual amounts for unit operating cost/NDCC and spending on capital at March 31, 2025 are incorporated by reference to Sherritt’s Management Discussion and Analysis (“MD&A”) for the three months ended March 31, 2025, dated May 13, 2025, which is available on Sherritt’s website (www.Sherritt.com). These amounts can be found in the Q1 2025 Financial Report in the Review of Operations section: Moa Joint Venture and Fort Site – page 11, Power – page 16. The MD&A is also available on SEDAR+ (www.sedarplus.ca). The primary determinants impacting unit operating costs are: for Moa Joint Venture – production levels, cobalt and fertilizer prices and input commodity prices, primarily sulphur; for Power, the primary determinants are production levels and maintenance costs. The primary determinants impacting spending on capital are liquidity, timing of expenditures and foreign exchange rates (as most purchases are denominated in U.S. dollars).
