Irving, TX - October 15, 2026 - CMC (NYSE: CMC) (the "Company") today announced financial results for its fiscal fourth quarter and fiscal year ended August 31, 2026.

CEO Commentary

“Fiscal 2026 marked a transformational step forward for CMC. We continued to build organizational strength and enhance margin durability in our early-stage construction portfolio through our precast acquisitions, our successful TAG program, and our key growth investments, including our West Virginia micro mill. We also established a clear roadmap to fiscal 2029, setting ambitious and achievable targets with a focus on delivering long-term shareholder value,” said Peter Matt, President and Chief Executive Officer. "Our fourth quarter core EBITDA performance delivered solid year-over-year growth, driven by strong execution of our North American steel franchise and continued momentum of enterprise-wide TAG benefits. While broader demand conditions remain supportive, residential softness weighed on precast results in the period. With backlogs near record levels, a differentiated portfolio of solutions, and multiple value creation levers, we are well-positioned to deliver strong financial results and achieve our strategic goals in fiscal 2027."

1 Net leverage adjusted for acquisitions is a non-GAAP financial measure and is defined as net debt divided by modified consolidated EBITDA, both of which are also non-GAAP financial measures. Net debt is calculated as total debt minus cash and cash equivalents. Modified consolidated EBITDA is calculated as adjusted EBITDA for the trailing 12-month period, adjusted to (a) eliminate the impact of approximately $15.4 million of interest expense related to the judgment in the Pacific Steel Group litigation, (b) eliminate actual results from the precast business since the respective acquisition dates and (c) include $212 million of annualized EBITDA contribution from the precast business. Reconciliations to the most directly comparable measures prepared and presented in accordance with GAAP can be found in the financial tables that follow.

Adjusted earnings per diluted share $ 2.09  $ 1.73  $ 1.37  20.8  % 52.6  %

For the fourth quarter of fiscal 2026, the Company reported consolidated net earnings of $212.5 million or $1.91 per diluted share, up from $1.35 in the prior year period, due in part to a lower effective tax rate. Adjusted earnings were $233.6 million, or $2.09 per diluted share, an increase of 52.6% on a per-share basis versus the comparable prior year period.

Consolidated core EBITDA for the fiscal fourth quarter increased 35.1% year-over-year to $393.7 million, while core EBITDA margins expanded 100 basis points to 14.8%, driven by metal margin expansion and the inclusion of the higher-margin precast business. Relative to the fiscal third quarter, 11.3% core EBITDA growth was led by the North America Steel Group, where stronger margins and volume growth drove 60 basis points of core EBITDA margin expansion.

Business Segments - Fiscal Fourth Quarter 2026 Review

North America Steel Group

Fourth quarter North America Steel Group adjusted EBITDA increased 32.6% year-over-year to $317.5 million, while adjusted EBITDA margin increased to 16.4%, up from 14.8% in the prior year period. Segment performance reflects a combination of higher average selling price for steel products, merchant bar-led volume growth, and ongoing benefits from the Company’s TAG program.

Compared with the prior year period, metal margins increased $84 per ton to $652. Sequentially, metal margins improved by $42 per ton, driven primarily by a $32 per ton increase in average selling price while scrap costs declined $10 per ton. Sequential pricing growth reflects a balanced supply-demand environment, continued momentum in rebar and MBQ pricing, and ongoing commercial discipline.

Finished goods shipment volumes for the North America Steel Group increased 5.3% versus the prior year period. Merchant bar shipment volumes surged 27.5% year-over-year, and 16.0% sequentially, driven by continued strength in industrial applications, including data center-related activity, as well as our expanded merchant bar production capabilities at the Arizona 2 micro mill. Taken together, rebar and downstream product shipment volumes were essentially flat year-over-year and up 4.4% sequentially, reflecting our commercial discipline as well as our

(CMC Fourth Quarter Fiscal 2026 - 3)

differentiated capabilities that position us well to meet the complexity associated with large-scale megaproject demand.

Market conditions remain solid, with demand strength across the energy build-out, semiconductor manufacturing, industrial manufacturing, and key public infrastructure markets. These conditions have contributed to a healthy and growing backlog, with downstream backlog volumes increasing 5.0% sequentially and 15.5% year-over-year. Similarly, backlog pricing continues to trend higher, reflecting disciplined execution, healthy demand, and our differentiated market position across core end markets.

Construction Solutions Group

Construction Solutions Group ("CSG") fourth quarter net sales increased 94.5% to $431.4 million and adjusted EBITDA of $101.7 million was up 100.9% year-over-year. Adjusted EBITDA margin of 23.6% was up 80 basis points relative to the prior year period. In the period, precast sales and adjusted EBITDA were $190.8 million and $57.0 million, respectively. Precast adjusted EBITDA fell below management's prior expectations, primarily due to regional residential softness, which reduced volumes and created regional margin mix headwinds. Precast shipments decreased year-over-year with weakness in the Southeast that more than offset strong shipment growth in the Mid-Atlantic. Underlying precast demand remains healthy, with strong momentum in non-residential and infrastructure end markets. In the fourth quarter, bookings were up year-over-year and up 12.6% sequentially. Backlog increased roughly 3% from the prior year and nearly 4% from the fiscal third quarter, and average selling price continued to move higher, reflecting solid market fundamentals. These indicators reinforce our confidence in the outlook for the precast business and its ability to deliver higher growth, greater earnings stability, and stronger returns for CMC in 2027.

Tensar delivered results that were largely consistent with both the prior quarter and the year-ago period, capping off a strong fiscal 2026 in which profitability increased approximately 50%. Performance was driven by favorable construction activity across several key end markets, including data centers, energy, and infrastructure. Construction Services and Impact Metals also delivered strong revenue and adjusted EBITDA growth year on year. Performance Reinforcing Steel's results were lower due to a significant unplanned outage at Galvabar that impacted shipments during the quarter. Encouragingly, bookings, backlogs and pricing trends for that business remain strong, and the operational flexibility coming from the second Galvabar line, which will be commissioned later in calendar 2026, will further enhance our ability to serve demand and support future growth.

Europe Steel Group

For the fourth quarter, Europe Steel Group generated adjusted EBITDA of $15.6 million, versus $39.1 million in the prior year period, with the year-over-year comparison impacted by a $30.7 million CO₂ credit recognized in the prior year, while no credit was recognized in the current period. Metal margin expanded by $32 per ton year-over-year as average selling price increased $44 per ton and outpaced scrap costs, which increased $12 per ton over the same period. Finished goods shipment volumes for the Europe Steel Group increased 0.8% as lower rebar volumes were more than offset by strong growth in merchant bar and wire rod. Improved trade policies via the

(CMC Fourth Quarter Fiscal 2026 - 4)

EU Carbon Border Adjustment Mechanism ("CBAM") as well as the tariff-rate quota ("TRQ") system implemented July 1, 2026 are supporting a more constructive operating environment. Combined with gradually improving end-market demand trends, these developments reinforce our confidence in a return to mid-cycle performance levels.

Balance Sheet & Capital Allocation

As of August 31, 2026, cash, cash equivalents and restricted cash totaled $778.9 million and available liquidity was over $2.0 billion. Net leverage adjusted for acquisitions ended the quarter at 1.9x reflecting strong cash generation and balance sheet discipline.

During the quarter, CMC repurchased 383,333 shares of common stock valued at $26.7 million in the aggregate. As of August 31, 2026, $702.1 million remained available under the current share repurchase authorization.

On October 13, 2026, the board of directors declared a quarterly dividend of $0.20 per share of CMC common stock payable to stockholders of record on October 28, 2026. The dividend, to be paid on November 11, 2026, will mark the 248th consecutive quarterly payment by the Company.

Outlook

Mr. Matt added, “We expect fiscal 2027 will be another strong year for CMC, supported by a healthy and balanced market backdrop and the growing contribution from our value creation levers, including TAG, our growth investments, and an evolving early-stage construction portfolio. Our focus remains on delivering profitable growth, improving free cash flow generation, enhancing shareholder returns, and, above all, continuing to advance our strategic agenda for a stronger CMC."

For the first quarter of fiscal 2027, we continue to expect healthy operating performance across the portfolio with normal seasonal factors and input cost dynamics to impact results sequentially:

•For the North America Steel Group, improved pricing is expected to largely offset higher scrap costs, startup expenses, and a slight seasonal decline in shipments, resulting in adjusted EBITDA that is expected to be nearly flat in comparison to the fourth quarter.

•Within the Construction Solutions Group, adjusted EBITDA is expected to be down sequentially reflecting typical seasonal trends impacting the end market activity of this segment.

•Meaningful sequential growth in adjusted EBITDA is anticipated for the Europe Steel Group with the first quarter benefiting from improving operating conditions and a CO2 credit.

NON-GAAP FINANCIAL MEASURES (UNAUDITED)

This press release contains financial measures not derived in accordance with U.S. generally accepted accounting principles ("GAAP"). Reconciliations to the most comparable GAAP measure are provided below.

Adjusted EBITDA, core EBITDA, core EBITDA margin and adjusted earnings are non-GAAP financial measures. Adjusted earnings per diluted share is defined as adjusted earnings on a diluted per share basis. Core EBITDA margin is defined as core EBITDA divided by net sales. The adjustment "Settlement of New Markets Tax Credit transactions" 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. 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, primarily represents interest expense on the judgment amount. The adjustments “Acquisition and integration related costs” and "Acquisition, integration and financing related costs" represent nonrecurring fees associated with the Foley Products Company, LLC (“Foley”) and Concrete Pipe and Precast, LLC (“CP&P”) acquisitions. The adjustment "Purchase accounting effect on inventory" represents a one time fair value adjustment on inventory associated with the Foley and CP&P acquisitions. The adjustment "Amortization of acquired contract backlog" represents the amortization of the contract backlog intangible asset from the Foley and CP&P acquisitions.

Net leverage adjusted for acquisitions is a non-GAAP financial measure and is defined as net debt divided by modified consolidated EBITDA, both of which are also non-GAAP financial measures. Net debt is calculated as total debt minus cash and cash equivalents. Modified consolidated EBITDA is calculated as adjusted EBITDA for the trailing 12-month period, adjusted to (a) eliminate the impact of approximately $15.4 million of interest expense related to the judgment in the Pacific Steel Group litigation, (b) eliminate actual results from the precast business since the respective acquisition dates and (c) include $212 million of annualized EBITDA contribution from the precast business. The estimated annualized EBITDA contribution from the precast business was derived by annualizing the precast business’s actual results from the respective acquisition dates through August 31, 2026. The calculation also excludes the impact of the purchase accounting effect on inventory. The annualized figure assumes that the precast platform’s results for the post-acquisition period are representative of a full fiscal year. The figure does not reflect actual results the precast platform generated or will generate in any 12-month period, and it was not prepared in accordance with Article 11 of Regulation S-X. Results for future periods may differ materially.

Non-GAAP financial measures should be viewed in addition to, and not as alternatives to, the most directly comparable measures derived in accordance with GAAP and may not be comparable to similar measures presented by other companies. However, we believe that the non-GAAP financial measures provide relevant and useful information to management, investors, analysts, creditors and other interested parties in our industry as they allow: (i) comparison of our earnings to those of our competitors; (ii) a supplemental measure of our underlying business operational performance; and (iii) the assessment of period-to-period performance trends. Furthermore, management believes net leverage adjusted for acquisitions provide useful information to investors, analysts, creditors and other interested parties about the Company's financial condition. Management uses non-GAAP financial measures to evaluate financial performance and, more specifically, uses net leverage adjusted for acquisitions to monitor the Company's balance sheet and make capital allocation decisions. We have not reconciled the forward-looking estimates of TAG-related EBITDA benefits to comparable GAAP measures because applicable information for future periods, on which these reconciliations would be based, is not readily available due to uncertainty regarding, and the potential variability of metal margins, U.S. trade policy, cost levels of key production inputs, construction activity and related product demand and other factors. Accordingly, reconciliations of the forward-looking estimates of TAG-related EBITDA benefits to net earnings are not available at this time without unreasonable effort.

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, 2025, 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 additional steelmaking capacity expected to come online from a number of electric arc furnace projects in the U.S.; the impact of geopolitical conditions, including political turmoil and volatility, regional conflicts, terrorism and war on the global economy, inflation, energy supplies and raw materials; 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; operating and startup 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; our ability to successfully execute our TAG operational and commercial excellence program and other transformation initiatives, including the realization of anticipated benefits within the expected timeframes; attention to environmental, social and governance (“ESG”) matters, including any targets or other ESG, environmental justice or regulatory initiatives; 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; availability and pricing of electricity, electrodes and natural gas for mill operations; our ability to hire and retain key executives and other employees; 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, including risks related to the Pacific Steel Group (“PSG”) litigation; risk of injury or death to employees, customers or other visitors to our operations; and civil unrest, protests and riots.

Q 4 F Y 2 0 2 6 S u p p l e m e n t a l S l i d e s 24 Definitions for non-GAAP financial measures ADJUSTED EARNINGS Adjusted earnings is a non-GAAP financial measure that is equal to earnings (loss) before asset impairments and settlement for New Markets Tax Credit transactions, including the estimated income tax effects thereof. 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. Adjusted earnings also excludes litigation expense, unrealized (gain) loss on undesignated commodity hedges and acquisition, integration and financing related costs, amortization of acquired contract backlog and purchase accounting effect on inventory. Adjusted earnings 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 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 (loss) before interest expense and income taxes. It also excludes recurring non-cash charges for depreciation and amortization, asset impairments 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. CONSOLIDATED 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 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. NET DEBT Net debt is defined as total long-term debt plus the current portion of long-term debt, less short-term borrowings (representing outstanding proceeds under the Poland accounts receivable facility), less cash and cash equivalents. NET LEVERAGE ADJUSTED FOR ACQUISITIONS Net leverage adjusted for acquisitions is a non-GAAP financial measure and is defined as net debt divided by modified consolidated EBITDA, both of which are also non-GAAP financial measures. Net debt is calculated as total debt minus cash and cash equivalents. Modified consolidated EBITDA is calculated as adjusted EBITDA for the trailing 12-month period, adjusted to (a) eliminate the impact of interest expense related to the judgment in the Pacific Steel Group litigation, which is $16 million for the Post Precast Closing and $15.4 million for each of Q2’26, Q3’26 and Q4’26, (b) eliminate actual results from the precast business since the respective acquisition dates and (c) include an estimate of annualized EBITDA contribution from the precast business, which is $245 million for the Post Precast Closing, Q2’26 and Q3’26 figures and $212 million for the Q4’26 figure. The annualized EBITDA contribution from the precast business used in the Q4’26 calculation was derived by annualizing the precast business’s actual results from the respective acquisition dates through August 31, 2026. The calculation also excludes the impact of the purchase accounting effect on inventory. The annualized figure used in the Q4’26 calculation assumes that the precast platform’s results for the post-acquisition period are representative of a full fiscal year. The figure does not reflect actual results the precast platform generated or will generate in any 12-month period, and it was not prepared in accordance with Article 11 of Regulation S-X. Results for future periods may differ materially. RETURN ON INVESTED CAPITAL Return on Invested Capital is defined as: 1) after-tax operating profit divided by 2) total assets less cash & cash equivalents less non-interest-bearing liabilities. For annual measures, trailing 5-quarter averages are used for balance sheet figures. During the fourth quarter of 2025, the Company modified its method of calculating adjusted EBITDA to exclude the impact of unrealized gains and losses from undesignated commodity derivatives. This change was primarily driven by heightened volatility in copper forward markets during 2025, 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 recast adjusted EBITDA, core EBITDA, core EBITDA margin, adjusted earnings and adjusted earnings per diluted share for all prior periods to conform to this presentation.
