• Steel product margins over scrap continued to expand on a y/y basis in North America, but have compressed in Europe − Margins were up $147 per ton y/y in North America, down $9 per ton y/y in Europe • Downstream average selling price increased $51 per ton from the prior quarter, a reflection of ongoing repricing of CMC’s backlog driven by higher priced new contracts • Downstream backlog volume grew on a year-over-year basis for sixth consecutive quarter • North America controllable costs per ton of finished steel were relatively flat sequentially and up y/y − Early signs that per unit costs for certain inputs may have peaked • Energy costs in Europe segment increased from the first quarter of FY 2022, but were likely a source of competitive advantage given: − Hedged position provided large cost offset − Electricity rates in the Polish market have experienced less volatility compared to Western European countries • Q1 results in Europe negatively impacted by higher energy costs per ton, selling higher cost inventory into a declining price environment, and a weakening Polish Zloty • Q2 financial results are expected to be good compared to historical standards • Finished steel shipments should follow a normal seasonal pattern; historically down from Q1 • Volumes in North America should be supported by a robust downstream backlog, as well as end market strength • Volumes in Europe could be impacted by negative economic sentiment and broad uncertainty during the winter months surrounding the ongoing energy crisis • Margins over scrap in both North America and Europe are likely to decline from first quarter levels Pe rf or m an ce D riv er s O ut lo ok Q1 Operational Update Q1 FY23 Supplemental Slides │ January 9, 2023 12

Definitions for non-GAAP financial measures Q1 FY23 Supplemental Slides │ January 9, 2023 27 ADJUSTED EARNINGS Adjusted earnings is a non-GAAP financial measure that is equal to earnings before debt extinguishment costs, certain gains on sale of assets, asset impairments, purchase accounting effect on inventory, mill operational start-up costs, acquisition and integration related costs and other, including the estimated income tax effects thereof. Adjusted earnings should not be considered as an alternative to net earnings or any other performance measure derived in accordance with GAAP. However, we believe that adjusted earnings provides relevant and useful information to investors as it allows: (i) a supplemental measure of our ongoing core performance and (ii) the assessment of period-to-period performance trends. Management uses adjusted earnings to evaluate our financial performance. Adjusted earnings may be inconsistent with similar measures presented by other companies. Adjusted earnings per diluted share (or adjusted EPS) is defined as adjusted earnings on a diluted per share basis. CORE EBITDA Core EBITDA is the sum of net earnings before interest expense and income taxes. It also excludes recurring non-cash charges for depreciation and amortization, asset impairments, and amortization of acquired unfavorable contract backlog. Core EBITDA also excludes debt extinguishment costs, non-cash equity compensation, certain gains on sale of assets, certain facility closure costs, acquisition settlement costs, labor cost government refunds, acquisition and integration related costs, mill operational start-up costs, CMC Steel Oklahoma incentives, severance, and purchase accounting effect on inventory. 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.
