The statements in this presentation that are not historical statements, are forward-looking statements. These forward-looking statements can generally be identified by phrases such as we or our management “expects,” “anticipates,” “believes,” “estimates,” “future,” “intends,” “may,” “plans to,” “ought,” “could,” “will,” “should,” “likely,” “appears,” “projects,” “forecasts,” “outlook” or other similar words or phrases, as well as by discussions of strategy, plans or intentions. Our forward-looking statements are based on management’s expectations and beliefs as of the date of this presentation. Although we believe that our expectations are reasonable, we can give no assurance that these expectations will prove to have been correct, and actual results may vary materially. Except as required by law, we undertake no obligation to update, amend or clarify any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, new information or circumstances or any other changes. Important factors that could cause actual results to differ materially from our expectations include those described in our filings with the Securities and Exchange Commission, including, but not limited to, in Part I, Item 1A, “Risk Factors” of our annual report on Form 10-K for the fiscal year ended August 31, 2023, as well as the following: changes in economic conditions which affect demand for our products or construction activity generally, and the impact of such changes on the highly cyclical steel industry; rapid and significant changes in the price of metals, potentially impairing our inventory values due to declines in commodity prices or reducing the profitability of downstream contracts within our vertically integrated steel operations due to rising commodity pricing; excess capacity in our industry, particularly in China, and product availability from competing steel mills and other steel suppliers including import quantities and pricing; the impact of the Russian invasion of Ukraine on the global economy, inflation, energy supplies and raw materials; increased attention to environmental, social and governance (“ESG”) matters, including any targets or other ESG or environmental justice initiatives; operating and start-up risks, as well as market risks associated with the commissioning of new projects could prevent us from realizing anticipated benefits and could result in a loss of all or a substantial part of our investments; impacts from global public health crises on the economy, demand for our products, global supply chain and on our operations; compliance with and changes in existing and future laws, regulations and other legal requirements and judicial decisions that govern our business, including increased environmental regulations associated with climate change and greenhouse gas emissions; involvement in various environmental matters that may result in fines, penalties or judgments; evolving remediation technology, changing regulations, possible third-party contributions, the inherent uncertainties of the estimation process and other factors that may impact amounts accrued for environmental liabilities; potential limitations in our or our customers' abilities to access credit and non-compliance with their contractual obligations, including payment obligations; activity in repurchasing shares of our common stock under our share repurchase program; financial and non-financial covenants and restrictions on the operation of our business contained in agreements governing our debt; our ability to successfully identify, consummate and integrate acquisitions and realize any or all of the anticipated synergies or other benefits of acquisitions; the effects that acquisitions may have on our financial leverage; risks associated with acquisitions generally, such as the inability to obtain, or delays in obtaining, required approvals under applicable antitrust legislation and other regulatory and third-party consents and approvals; lower than expected future levels of revenues and higher than expected future costs; failure or inability to implement growth strategies in a timely manner; the impact of goodwill or other indefinite-lived intangible asset impairment charges; the impact of long-lived asset impairment charges; currency fluctuations; global factors, such as trade measures, military conflicts and political uncertainties, including changes to current trade regulations, such as Section 232 trade tariffs and quotas, tax legislation and other regulations which might adversely impact our business; availability and pricing of electricity, electrodes and natural gas for mill operations; our ability to hire and retain key executives and other employees; our ability to successfully execute leadership transitions; competition from other materials or from competitors that have a lower cost structure or access to greater financial resources; information technology interruptions and breaches in security; our ability to make necessary capital expenditures; availability and pricing of raw materials and other items over which we exert little influence, including scrap metal, energy and insurance; unexpected equipment failures; losses or limited potential gains due to hedging transactions; litigation claims and settlements, court decisions, regulatory rulings and legal compliance risks; risk of injury or death to employees, customers or other visitors to our operations; and civil unrest, protests and riots.

25 Definitions for non-GAAP financial measures ADJUSTED EARNINGS Adjusted earnings is a non-GAAP financial measure that is equal to earnings before settlement of New Market Tax Credit transactions, asset impairments, mill operational commissioning costs, including the estimated income tax effects thereof. The adjustment for mill operational commissioning costs represents costs incurred during the final stages of testing and commissioning of the Company’s third micro mill, until the point at which the micro mill is fully operational. The adjustment for settlement of 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. 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, and asset impairments. Core EBITDA also excludes settlement of New Market Tax Credit transactions, non-cash equity compensation, and mill operational commissioning costs. The adjustment for mill operational commissioning costs represents costs incurred during the final stages of testing and commissioning of the Company’s third micro mill, until the point at which the micro mill is fully operational. The adjustment for settlement of 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), 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 before interest expense, income taxes, depreciation and amortization expense, asset impairments. Adjusted EBITDA 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 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.
