The accompanying audited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and include all normal recurring adjustments necessary to present fairly the consolidated balance sheets and the consolidated statements of earnings, comprehensive income, cash flows and stockholders' equity for the periods indicated. Any reference in this Form 10-K to a year refers to the fiscal year ended August 31st of that year, unless otherwise stated.

CMC is an innovative solutions provider helping build a stronger, safer and more sustainable world. Through an extensive manufacturing network principally located in the United States ("U.S.") and Central Europe, CMC offers products and technologies to meet the critical reinforcement needs of the global construction sector. CMC’s solutions support early-stage construction across a wide variety of applications, including infrastructure, non-residential, residential, industrial and energy generation and transmission.

The North America Steel Group segment is composed of a vertically integrated network of recycling facilities, steel mills and fabrication operations located in the U.S. The recycling facilities process ferrous and nonferrous scrap metals (collectively referred to as "raw materials") for use by manufacturers of metal products. The steel mill operations consist of six electric arc furnace ("EAF") mini mills, three EAF micro mills and one rerolling mill. The steel mills manufacture finished long steel products including reinforcing bar ("rebar"), merchant bar, light structural and other special sections and wire rod, as well as semi-finished billets for rerolling and forging applications (collectively referred to as "steel products" in the context of the North America Steel Group segment). The fabrication operations primarily fabricate rebar and steel fence posts and offer post-tension cable products (collectively referred to as "downstream products" in the context of the North America Steel Group segment). The general strategy in the North America Steel Group segment is to optimize the Company's vertically integrated value chain to maximize profitability by obtaining the lowest possible input costs and highest possible selling prices. The Company operates the recycling facilities to provide low-cost scrap to the steel mills and the fabrication operations to optimize the steel mill volumes. The North America Steel Group segment's products are sold to steel mills and foundries, as well as construction, fabrication and other manufacturing industries.

The Emerging Businesses Group segment consists of CMC Construction Services products ("construction products"), Tensar products and solutions (collectively referred to as "ground stabilization solutions"), CMC Impact Metals, performance reinforcing steel products (collectively referred to as "downstream products" in the context of the Emerging Businesses Group segment) and CMC Bridge Systems.

•Tensar sells geogrids and Geopier foundation systems. Geogrids are polymer-based products used for ground stabilization, soil reinforcement and asphalt optimization in construction applications, including roadways, public infrastructure and industrial facilities. Geopier foundation systems are rammed aggregate pier and other foundation solutions that increase the load-bearing characteristics of ground structures and working surfaces and can be applied in soil types and construction situations where traditional support methods are impractical or would make a project infeasible.

•CMC's group of performance reinforcing steel offerings include innovative products such as Galvabar (galvanized rebar with a zinc alloy coating that provides corrosion protection and post-fabrication formability), ChromX (designed for high-strength capabilities, corrosion resistance and a service life of more than 100 years) and CryoSteel (a cryogenic reinforcing steel that exceeds minimum performance requirements for strength and ductility at extremely low temperatures).

•Through the Company's licensing agreement with InQuik Inc., CMC Bridge Systems is the authorized provider of InQuik Bridges in the U.S. CMC Bridges are a patented prefabricated and modular system for constructing reinforced concrete bridge components off-site, which are then installed on-site with poured concrete for a cast-in-place structure.

The strategy in the Emerging Businesses Group segment is to provide construction-related solutions and value-added products with strong underlying growth fundamentals to serve domestic and international markets adjacent to those served by the vertically integrated operations in the North America Steel Group segment and the Europe Steel Group segment. To execute this strategy, the Company (i) develops proprietary products and solutions that deliver high value to customers by reducing costs and construction time, (ii) provides concrete-related construction products, equipment, and services and (iii) produces reinforcing steel products with increased strength, durability and corrosion resistance to support sustainable concrete construction.

The Europe Steel Group segment is composed of a vertically integrated network of recycling facilities, an EAF mini mill and fabrication operations located in Poland. The scrap metal recycling facilities process ferrous scrap metals for use almost exclusively by the mini mill. The steel products manufactured by the mini mill include rebar, merchant bar and wire rod as well as semi-finished billets. The products manufactured by this segment's fabrication operations include fabricated rebar, wire mesh, welded steel mesh, wire rod, cold-rolled rebar, cold-rolled wire rod, assembled rebar cages and other fabricated rebar by-products (collectively referred to as "downstream products" in the context of the Europe Steel Group segment). The strategy in the Europe Steel Group segment is to optimize profitability of the products manufactured by the mini mill and is executed in the same manner as in the North America Steel Group segment. The Europe Steel Group segment's products are sold primarily to fabricators, manufacturers, distributors and construction companies.

The preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and reported amounts of net sales and expenses during the reporting period. Significant items subject to such estimates and assumptions include revenue recognition, income taxes, inventories, acquisitions, goodwill and other intangible assets, long-lived assets, derivative financial instruments and contingencies. Actual results could differ significantly from these estimates and assumptions.

Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration received or expected to be received in exchange for those goods or services. The Company's performance obligations arise from (i) sales of raw materials, steel products, downstream products, construction products and ground stabilization solutions and (ii) installation services performed by its fabrication operations. The shipment of products to customers is considered a fulfillment activity, and amounts billed to customers for shipping and freight are included in net sales, and the related costs are included in cost of goods sold. Net sales are presented net of taxes remitted to taxing authorities.

The majority of the Company's revenue is recognized at a point in time concurrent with the transfer of control, which usually occurs, depending on shipping terms, upon shipment or customer receipt. Certain revenue from sales of downstream products in the North America Steel Group segment is recognized over time, as discussed below. Remaining revenue from sales of downstream products in the North America Steel Group segment is recognized based on the amount the Company has a right to invoice as a practical expedient.

Each of the North America Steel Group segment's fabrication contracts represents a single performance obligation. For contracts where the Company provides fabricated rebar and installation services, revenue is recognized over time using an input measure of progress based on contract costs incurred to date compared to total estimated contract costs ("input measure"). This input measure provides a reasonable depiction of the Company’s progress toward satisfaction of the performance obligation, as there is a direct relationship between costs incurred by the Company and the transfer of the fabrication and installation services. Revenue from fabrication contracts where the Company does not provide installation services is recognized over time using an output measure of progress based on tons shipped compared to total estimated tons ("output measure"). This output measure provides a reasonable depiction of the transfer of contract value to the customer, as there is a direct relationship between the units shipped by the Company and the transfer of the fabricated rebar. If total estimated costs on any contract are greater than the net contract revenues, the Company recognizes the entire estimated loss in the period the loss becomes known. The cumulative effect of revisions to estimates related to net contract revenues, costs to complete or total planned quantity is recorded in the period in which such revisions are identified.

The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records an asset when revenue is recognized prior to invoicing and a liability when revenue is recognized subsequent to invoicing. Payment terms and conditions vary by contract type, although the Company generally requires customers to pay 30 days after the Company satisfies the performance obligations. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the contracts do not include a significant financing component.

The Company maintains an allowance for doubtful accounts for accounts receivable it estimates will not be collected based on market conditions, customers' financial condition and other factors. Historically, these allowances have not been material. The Company reviews and sets credit limits for each customer. The Europe Steel Group segment uses credit insurance to ensure payment in accordance with the terms of sale. Generally, collateral is not required. Approximately 15% and 13% of total receivables at August 31, 2025 and 2024, respectively, were financially assured.

Inventories are stated at the lower of cost or net realizable value. Cost is determined by the weighted average cost method. Adjustments to inventory may be due to changes in price levels, assumptions about market conditions, obsolescence, damage, physical deterioration and other causes. Adjustments required to reduce the carrying value of inventory to net realizable value are recorded as a charge to cost of goods sold within the consolidated statements of earnings.

Elements of cost in finished goods inventory, in addition to the cost of material, include depreciation, utilities, consumable production inputs, maintenance, production, wages and transportation costs. Additionally, the costs of departments that support production, including materials management and quality control, are allocated to inventory.

The Company evaluates impairment of its property, plant and equipment to be held and used whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. For each asset or asset group held for use with indicators of impairment, the Company compares the undiscounted net cash flows to be generated from the use and eventual disposition of the asset or asset group with its net carrying value. If the net carrying value of the asset or asset

group exceeds the estimated undiscounted net future cash flows, the excess of the net carrying value over the estimated fair value is charged to impairment loss. Property, plant and equipment held for sale are reported at the lower of the carrying amount or the estimated sales price, less estimated costs to sell.

During 2024, the Company committed to a plan to sell a rebar fabrication facility within the North America Steel Group segment and determined that the disposal group met the criteria to be classified as held for sale. Upon concluding that the disposal group met the held for sale criteria, the Company recorded an impairment charge of $6.6 million to record the disposal group at the lower of its carrying value or fair value less costs to sell.

During 2023, historical and current period operating losses were determined to be triggering events for three long-lived asset groups associated with downstream fabricated rebar operations. The Company reviewed the undiscounted future cash flows for the long-lived asset groups for recoverability, which indicated that the net carrying values of certain right-of-use ("ROU") assets included in one long-lived asset group were not recoverable. Therefore, such ROU assets were evaluated for impairment by comparing the estimated fair values of the ROU assets to their net carrying values, which resulted in a non-cash impairment of $3.5 million during the fourth quarter of 2023, included in asset impairments in the consolidated statement of earnings. Further discussion regarding non-recurring fair value remeasurements is included in Note 11, Fair Value.

The Company capitalizes certain direct internal and external costs for the development of internal-use software based on the stage of development as well as the nature of the costs incurred. Capitalization of qualifying internal-use software costs begins when the preliminary project stage is completed, management with the relevant authority, implicitly or explicitly, authorizes and commits to funding the project and it is probable that the project will be completed and the software will perform as intended. Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete and the software is ready for its intended purpose. Costs incurred in the preliminary project stage and post implementation phases, including costs associated with post-configuration training and repairs and maintenance of the developed technologies, are expensed as incurred.

Software development includes costs associated with a cloud computing arrangement ("CCA"), such as software as a service or other hosting arrangements. If the CCA includes a software license, the software license element of the arrangement is accounted for in the same manner as the acquisition of internal-use software. If the CCA does not include a software license, the service element of the arrangement is accounted for as a service contract. The Company defers certain implementation costs for its CCAs that are service contracts, which are included in prepaids and other current assets and other noncurrent assets in the consolidated balance sheets. The Company amortizes deferred implementation costs in a CCA over the life of the service contract.

The Company's leases are primarily for real property and equipment. The Company determines if an arrangement is a lease at the inception of a contract by assessing whether the Company has the right to direct the use of, and obtain substantially all the economic benefits from, a specific asset identified in the contract. The ROU assets represent the Company's right to use the underlying assets for the lease term, and the lease liabilities represent the obligation to make lease payments arising from the leases. The Company's ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments to be made over the lease term. Certain of the Company's lease agreements contain options to extend the lease. The Company evaluates these options on a lease-by-lease basis, and if the Company determines it is reasonably certain to be exercised, the lease term includes the extension. The Company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments, and lease expense is recognized on a straight-line basis over the lease term. The incremental borrowing rate is the rate of interest the Company could borrow on a collateralized basis over a similar term with similar payments. The Company does not include leases with an initial term of twelve months or less in the ROU asset or lease liability balances.

Certain of the Company's lease agreements include payments for variable costs not determinable upon lease commencement, including mileage, utilities, fuel and inflation adjustments. These variable lease payments are recognized in cost of goods sold and selling, general and administrative ("SG&A") expenses, but are not included in the ROU asset or lease liability balances. The Company's lease agreements do not contain any material residual value guarantees, restrictions or covenants.

Government assistance, including non-monetary grants, herein collectively referred to as grants, is not recognized until there is reasonable assurance that the Company will comply with the conditions of the grant and will receive it. Generally, government grants fall into two categories: grants related to assets and grants related to income.

Grants related to assets are government grants for the purchase, construction or other acquisition of long-lived assets. The Company accounts for grants related to assets by deducting the grant in arriving at the carrying amount of the asset on the consolidated balance sheets. Non-monetary grants are recognized at fair value. The Company recognizes the grant in profit or loss over the life of the depreciable asset as a reduction to depreciation expense. Grants related to non-depreciable assets may require the fulfillment of certain obligations and, in such cases, are recognized in profit or loss over the periods that bear the cost of meeting the obligations. As an example, a grant of land that is conditional upon constructing a building on the site is recognized as a reduction to depreciation expense over the life of the building.

Grants related to income are any grants that are not considered grants related to assets, such as grants to compensate for certain expenses. Grants related to income are recognized in profit or loss on a systematic basis upon meeting the recognition criteria specified in the grants and during the periods when the expenses being compensated by the grants are incurred.

During 2025, 2024 and 2023, the Company was awarded $74.7 million, $29.2 million and $9.5 million, respectively, in government grants related to income as part of the compensation scheme for energy-intensive sectors and sub-sectors established by the Energy Regulatory Office in Poland (the "Poland Compensation Scheme Act" or "PCSA"). The purpose of the PCSA each year was to provide aid to energy-intensive companies to offset indirect costs of rising carbon emission rights included in energy costs. The amount of government assistance awarded by the PCSA each year was dependent upon the Company meeting certain electricity consumption thresholds and the number of other applicants. The government assistance received and recognized under the PCSA each year is not subject to recapture. The PCSA grants were recognized in the Europe Steel Group segment as reductions to cost of goods sold in the consolidated statements of earnings.

During 2025, 2024 and 2023, the Company was awarded $4.0 million, $40.2 million and $4.3 million, respectively, in government grants related to income as part of the annual Polish state aid programs established for rising electricity and natural gas prices (the "Energy Aid Programs"). The Energy Aid Programs were established by the Polish Ministry of Development and Technology to mitigate the effects of sudden increases in electricity and natural gas prices in Poland for companies that met required energy intensity and sectorial conditions and met certain financial metrics. The government assistance received and recognized under the Energy Aid Programs each year is not subject to recapture. The grants from the Energy Aid Programs were recognized in the Europe Steel Group segment as reductions to cost of goods sold in the consolidated statements of earnings.

During 2023, the Company entered into an agreement with the West Virginia Economic Development Authority (the "WVEDA") to permanently finance a portion of the costs to construct the Company's fourth micro mill, which is under development in Berkeley County, West Virginia. Under this agreement, the Company can receive up to $75.0 million in aggregate disbursements in the form of a forgivable loan for eligible costs incurred from June 21, 2023 through June 20, 2027 (the "Completion Date"). Eligible costs include the acquisition of land and buildings, the acquisition and installation of machinery and equipment and necessary construction costs. The Company anticipates receiving disbursements over this period upon achieving certain capital investment and employment thresholds. Amounts received under the agreement are subject to recapture in the event that the Company fails to achieve certain minimum investment and employment thresholds prior to the Completion Date. The Company has determined that amounts received under the agreement are grants related to assets. During 2025 and 2023, the Company received $50.0 million and $5.0 million, respectively, in benefits from the WVEDA as a result of meeting certain investment thresholds; amounts received were recognized in the North America Steel Group segment and the cumulative benefits reduced construction in process in the consolidated balance sheets.

Goodwill and other indefinite-lived intangible assets are tested for impairment annually as of the first day of the Company's fourth quarter, and between annual tests whenever events or circumstances indicate that the carrying value of a reporting unit, including goodwill, or an indefinite-lived intangible asset exceeds its fair value. To evaluate goodwill and other indefinite-lived intangible assets for impairment, the Company may use qualitative assessments to determine whether it is more likely than not that the fair value of a reporting unit, including goodwill, or an indefinite-lived intangible asset is less than its carrying amount. The qualitative assessments consider multiple factors, including the current operating environment, historical and future financial performance and industry and market conditions. If an initial qualitative assessment identifies that it is more likely

than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed. The Company may elect to bypass the qualitative assessment and instead perform a quantitative impairment test to calculate the fair value of the reporting unit in comparison to its associated carrying value.

The Company's reporting units represent an operating segment or one level below an operating segment. When performing a quantitative impairment test, the Company estimates the fair value of its reporting units using a weighting of fair values derived from the income and market approaches. Using the income approach, the Company determines the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into account industry and market conditions. The discount rate is based on a weighted average cost of capital adjusted for the relevant risk associated with the characteristics of the reporting unit. The market approach estimates fair value based on market multiples of earnings derived from comparable publicly traded companies with similar operating and investment characteristics to the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is indicated in the amount that the carrying value exceeds the fair value of the reporting unit, not to exceed the goodwill value for the reporting unit.

When estimating the fair value of indefinite-lived intangible assets using a quantitative approach, the Company applies the relief from royalty method, an income approach. Significant inputs to estimate the fair value of the indefinite-lived intangible assets include projected revenue growth rates, royalty rates and discount rates.

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives and are tested for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment charges are recorded on finite-lived intangible assets when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts.

The Company accrues for claims and litigation, including environmental investigation and remediation costs, when they are both probable and the amount can be reasonably estimated. In the event that estimates or assumptions differ from actual results, adjustments are made in subsequent periods to reflect more current information. The Company expenses legal fees as incurred.

Environmental costs are based on estimates regarding the sites for which the Company will be responsible, the scope and cost of work to be performed at each site, the portion of costs that will be shared with other parties and the timing of remediation. Where timing and amounts cannot be reasonably determined, a range is estimated and the lower end of the range is recorded.

The Company recognizes stock-based equity and liability awards at fair value. The fair value of each stock-based equity award is estimated at the grant date using either the Black-Scholes or Monte Carlo pricing model. The total compensation cost for these awards is amortized over the requisite service period using the accelerated method of amortization for grants with graded vesting or the straight-line method for grants with cliff vesting. Stock-based liability awards are measured at fair value at the end of each reporting period and fluctuate based on the price of CMC common stock and performance relative to the targets.

CMC and its U.S. subsidiaries file a consolidated federal income tax return. Deferred income taxes are provided for temporary differences between financial statement and income tax bases of assets and liabilities. The principal differences are described in Note 12, Income Tax. Benefits from income tax credits are recognized as a component of income tax expense in the period earned. The Company records income tax positions based on a more likely than not threshold for sustaining the position upon examination by taxing authorities with full knowledge of all relevant facts. The Company classifies interest and any statutory penalties recognized on a tax position as income tax expense.

The functional currency of the Company's foreign operations is the local currency of each respective country. Translation adjustments are reported as a component of accumulated other comprehensive income or loss. Transactions denominated in currencies other than the functional currency resulted in losses of $9.8 million, $7.7 million and $12.1 million in 2025, 2024 and 2023, respectively.

The Company recognizes derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. Derivatives that are not designated as hedges are adjusted to fair value through net earnings. Changes in the fair value of derivatives that are designated as hedges are recognized depending on the nature of the hedge. For fair value hedges, changes are recognized as an offset against the change in fair value of the hedged balance sheet item. When the derivative is designated as a cash flow hedge and is highly effective, changes are recognized in other comprehensive income (loss).

Gains or losses on derivative instruments are recognized in the consolidated statements of earnings when the instrument is sold, terminated, exercised, or expires, if it is an undesignated hedge or designated as a fair value hedge. If a derivative instrument is designated as a cash flow hedge, the cumulative unrealized gain or loss, which has been recognized in the statement of comprehensive income, is reclassified to the consolidated statements of earnings when the hedged transaction either impacts earnings or is no longer expected to occur.

The Company has established a fair value hierarchy that prioritizes the inputs to the valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement. Level 1 represents unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 represents quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) that are observable, either directly or indirectly. Level 3 represents valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires that an acquirer recognize and measure contract assets and liabilities acquired in a business combination in accordance with ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The Company adopted this standard on a prospective basis for the annual period beginning September 1, 2023. The adoption did not have an impact on the Company's consolidated financial statements at the time of adoption.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 requires, among other updates, enhanced disclosures about significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM"), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective adoption. The Company adopted the amendments in ASU 2023-07 for its fiscal year ended August 31, 2025. Based on the Company's assessment of significant segment expenses regularly provided to the CODM, cost of goods sold and SG&A expenses are now disclosed for each reportable segment. The amendment was applied retrospectively to all prior periods presented. See Note 19, Segment Information, for additional information.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 requires enhanced annual disclosures regarding the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and may be adopted on a prospective or retrospective basis. Early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and disclosures but does not expect it to have a material effect.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"). ASU 2024-03 requires disaggregated income statement expense disclosures related to functional or natural expense line items within continuing operations. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, and permits either prospective or retrospective adoption. Early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal Use Software ("ASU 2025-06"). ASU 2025-06 eliminates accounting consideration of software project development stages and clarifies the threshold applied to begin capitalizing costs. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years, and permits prospective, modified prospective, or retrospective adoption. Early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
