Net Debt to Adjusted EBITDA [1] See page 21 for definitions of non-GAAP measures 20 20

Definitions for non-GAAP financial measures CORE EBITDA Core EBITDA is the sum of net earnings (loss) before interest expense and income taxes. It also excludes recurring non-cash charges for depreciation and amortization, asset impairments, amortization of acquired unfavorable contract backlog, and unrealized (gain) loss on undesignated commodity hedges. Core EBITDA also excludes litigation expense, settlement for New Market Tax Credit transactions, non-cash stock-based compensation, loss on debt extinguishments, gains on sale of assets, acquisition settlements, acquisition and integration related costs, and purchase accounting effect on inventory. The adjustment “litigation expense” represents a provision recorded in the three months ended November 30, 2024 related to the judgment in the Pacific Steel Group litigation and, with respect to subsequent periods, interest expense on the judgment amount. The adjustment “settlement for New Markets Tax Credit transaction” represents the recognition of deferred revenue from 2016 and 2017 resulting from the Company’s participation in the New Markets Tax Credit program provided for in the Community Renewal Tax Relief Act of 2000 during the development of a micro mill, spooler and T-post shop located in eligible zones as determined by the Internal Revenue Service. Core EBITDA should not be considered an alternative to earnings (loss) from continuing operations or net earnings (loss), or as a better measure of liquidity than net cash flows from operating activities, as determined by GAAP. However, we believe that Core EBITDA provides relevant and useful information, which is often used by analysts, creditors and other interested parties in our industry as it allows: (i) comparison of our earnings to those of our competitors; (ii) a supplemental measure of our ongoing core performance; and (iii) the assessment of period-to-period performance trends. Additionally, Core EBITDA is the target benchmark for our annual and long-term cash incentive performance plans for management. Core EBITDA may be inconsistent with similar measures presented by other companies. ADJUSTED EBITDA Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA is the sum of the Company’s net earnings (loss) before interest expense, income taxes, depreciation and amortization expense, asset impairments, amortization of acquired unfavorable contract backlog, and unrealized (gain) loss on undesignated commodity hedges. Adjusted EBITDA should not be considered as an alternative to net earnings (loss), or any other performance measure derived in accordance with GAAP. However, we believe that adjusted EBITDA provides relevant and useful information to investors as it allows: (i) a supplemental measure of our ongoing performance and (ii) the assessment of period-to-period performance trends. Management uses adjusted EBITDA to evaluate our financial performance. Adjusted EBITDA may be inconsistent with similar measures presented by other companies. During the fourth fiscal quarter of 2025, the Company modified its method of calculating adjusted EBITDA to exclude the impact of unrealized gains and losses on undesignated commodity derivatives. This change was primarily driven by heightened volatility in copper forward markets, which introduced significant non-cash fluctuations unrelated to core operations. By removing this volatility, the revised metric provides a more representative view of operating performance and cash-generating capability. Accordingly, the Company evaluated the impact of this change on prior-period disclosures and has recast adjusted EBITDA, core EBITDA, core EBITDA margin, adjusted earnings and adjusted earnings per diluted share for all periods presented in this presentation. FREE CASH FLOW CONVERSION - NORMALIZED Free Cash Flow Conversion – Normalized is a non-GAAP financial measure. It is calculated as Core EBITDA (as defined above) less income tax expense, which is calculated using a 25% assumed tax rate applied to net earnings before interest expense and income taxes, and estimated maintenance capital expenditures. Maintenance capital expenditures represent an estimate of the capital required to sustain ongoing operations and exclude strategic or growth-related investments. Free Cash Flow Conversion – Normalized should not be considered an alternative to net cash flows from operating activities as determined by GAAP. However, we believe this metric provides relevant and useful information to investors and other stakeholders as it reflects the Company’s ability to convert earnings into recurring, sustainable cash flows available for capital allocation. Free Cash Flow Conversion – Normalized may be inconsistent with similar measures presented by other companies. NET DEBT Net debt is defined as total debt less cash and cash equivalents. NET LEVERAGE Net leverage is defined as net debt divided by trailing 12 month adjusted EBITDA from continuing operations. 21
