SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 2024
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES NATURE OF OPERATIONS Vulcan Materials Company (the “Company,” “Vulcan,” “we,” “our”), a New Jersey corporation, is the nation’s largest supplier of construction aggregates (primarily crushed stone, sand and gravel) and a major producer of aggregates-intensive downstream products such as asphalt mix and ready-mixed concrete. We operate primarily in the United States, and our principal product — aggregates — is used in most types of public and private construction projects and in the production of asphalt mix and ready-mixed concrete. Our primary focus is serving metropolitan markets in the United States that are expected to experience the most significant growth in population, households and employment. These three demographic factors are significant drivers of demand for aggregates. While aggregates is our focus and primary business, we produce and sell aggregates-intensive asphalt mix and/or ready-mixed concrete products in certain markets. BASIS OF PRESENTATION Our accompanying unaudited condensed consolidated financial statements were prepared in compliance with the instructions to Form 10-Q and Article 10 of Regulation S-X and thus do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements. We prepared the accompanying condensed consolidated financial statements on the same basis as our annual financial statements, except for the adoption of new accounting standards, if any, as described in Note 17. Our Condensed Consolidated Balance Sheet as of December 31, 2023 was derived from the audited financial statement, but it does not include all disclosures required by GAAP. In the opinion of our management, the statements reflect all adjustments, including those of a normal recurring nature, necessary to present fairly the results of the reported interim periods. For further information, refer to the consolidated financial statements and footnotes included in our most recent Annual Report on Form 10-K. Operating results for the three and six month periods ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. Our condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets, liabilities, revenues and expenses. The most significant estimates and assumptions included in the preparation of these financial statements are related to goodwill and long-lived asset impairments, business combinations and purchase price allocation, pension and other postretirement benefits, environmental compliance, claims and litigation including self-insurance, and income taxes (refer to the Critical Accounting Policies included in Item 7 of our most recent Annual Report on Form 10-K). Events that relate to conditions arising after June 30, 2024 will be reflected in management’s estimates for future periods. NONCONTROLLING INTEREST We own an 88% controlling interest in the Orca Sand and Gravel Limited Partnership (Orca) which was formed to develop the Orca quarry in British Columbia, Canada. The remaining 12% noncontrolling interest is held by the Namgis First Nation (Namgis). This noncontrolling interest consists of the Namgis’ share of the fair value equity in the partnership. Our condensed consolidated financial statements recognize the full fair value of all of the subsidiary’s assets and liabilities offset by the noncontrolling interest in total equity. RESTRICTED CASH Restricted cash primarily consists of cash proceeds from the sale of property held in escrow for the acquisition of replacement property under like-kind exchange agreements. The escrow accounts are administered by an intermediary. Cash restricted pursuant to like-kind exchange agreements remains restricted for a maximum of 180 days from the date of the property sale pending the acquisition of replacement property. Restricted cash may also include cash reserved by other contractual agreements (such as asset purchase agreements) for a specified purpose and therefore is not available for use for other purposes. Restricted cash is included with cash and cash equivalents in the accompanying Condensed Consolidated Statements of Cash Flows. INVENTORIES Inventories and supplies are stated at the lower of cost or net realizable value. Inventories are as follows: in millions June 30 December 31 June 30 Finished products $ 514.2 $ 494.4 $ 455.3 Raw materials 58.8 51.2 69.1 Products in process 8.8 6.5 7.2 Operating supplies and other 68.5 63.5 63.0 Total inventories $ 650.3 $ 615.6 $ 594.6 DISCONTINUED OPERATIONS In 2005, we sold substantially all the assets of our Chemicals business to a subsidiary of Occidental Chemical Corporation. The financial results of the Chemicals business are classified as discontinued operations in the accompanying Condensed Consolidated Statements of Comprehensive Income for all periods presented. Results from discontinued operations are as follows: in millions Three Months Ended Six Months Ended 2024 2023 2024 2023 Pretax loss $ (2.7) $ (4.9) $ (5.0) $ (7.9) Income tax benefit 0.7 1.2 1.3 2.1 Loss on discontinued operations, net of tax $ (2.0) $ (3.7) $ (3.7) $ (5.8) Our discontinued operations include charges related to general and product liability costs, including legal defense costs, and environmental remediation costs associated with our former Chemicals business (including certain matters as discussed in Note 8). There were no revenues from discontinued operations for the periods presented. EARNINGS PER SHARE (EPS) Earnings per share are computed by dividing net earnings by the weighted-average common shares outstanding (basic EPS) or weighted-average common shares outstanding assuming dilution (diluted EPS), as set forth below: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Weighted-average common shares outstanding 132.4 133.2 132.4 133.2 Dilutive effect of Stock-Only Stock Appreciation Rights 0.2 0.2 0.2 0.2 Other stock compensation awards 0.5 0.4 0.5 0.3 Weighted-average common shares outstanding, assuming dilution 133.1 133.8 133.1 133.7 All dilutive common stock equivalents are reflected in our earnings per share calculations. In periods of loss, shares that otherwise would have been included in our diluted weighted-average common shares outstanding computation would be excluded. Antidilutive common stock equivalents are not included in our earnings per share calculations. The number of antidilutive common stock equivalents for which the exercise price exceeds the weighted-average market price is as follows: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Antidilutive common stock equivalents 0.1 0.1 0.1 0.1 RECLASSIFICATIONS As a result of a first quarter 2024 change in our internal management reporting structure, prior period segment information has been revised to conform to our current segment reporting structure. This change had no impact on our prior consolidated results of operations, financial position or cash flows (refer to Note 13 for further information).

INCOME TAXES

INCOME TAXES	6 Months Ended
	Jun. 30, 2024
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Our estimated annual effective tax rate (EAETR) is based on full-year expectations of pretax earnings, statutory tax rates and permanent differences between book and tax accounting such as percentage depletion. For interim financial reporting, we calculate our quarterly income tax provision in accordance with the EAETR. Each quarter, we update our EAETR based on our revised full-year expectation of pretax earnings and calculate the income tax provision so that the year-to-date income tax provision reflects the EAETR. Significant judgment is required in determining our EAETR. In the second quarter of 2024, we recorded income tax expense from continuing operations of $94.4 million compared to $92.0 million in the second quarter of 2023. The increase in tax expense was primarily due to less excess tax benefits generated from share-based compensation recognized in the second quarter of 2024. For the first six months of 2024, we recorded income tax expense from continuing operations of $123.4 million compared to $108.6 million for the first six months of 2023. The increase in tax expense was primarily due to a discrete benefit related to a 2022 business disposition recognized in the first six months of 2023. In August 2022, the Inflation Reduction Act (IRA) was signed into law, effective for tax years beginning on or after January 1, 2023. The IRA introduced a corporate alternative minimum tax (CAMT) of 15% applicable to corporations with adjusted financial statement income in excess of $1 billion, as well as certain climate-related tax provisions. We were not subject to CAMT in 2023 and do not anticipate being subject to CAMT in 2024. As discussed in Note 8, in May 2022, Mexican government officials unexpectedly and arbitrarily shut down our Calica operations in Mexico. In 2023, Calica had deferred tax assets (including net operating losses) of $27.4 million against which we have a full valuation allowance recorded. In 2024, we project a $6.6 million increase in deferred tax assets against which a valuation allowance was recorded as a component of the EAETR in the first six months of 2024. A majority of the deferred tax assets relate to a net operating loss (NOL) carryforward which would expire between 2032 and 2034 if not utilized. Should the Mexican government lift the shutdown and/or if we are successful in our North American Free Trade Agreement (NAFTA) claim, we will reevaluate the need for a valuation allowance against the deferred tax assets. We project Alabama NOL carryforward deferred tax assets at December 31, 2024 of $68.4 million against which we have a valuation allowance of $49.5 million. Almost all of the Alabama NOL carryforward would expire between 2024 and 2029 if not utilized. A summary of our deferred tax assets and liabilities is included in Note 9 “Income Taxes” in our Annual Report on Form 10-K for the year ended December 31, 2023.

REVENUES

REVENUES	6 Months Ended
	Jun. 30, 2024
Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES Revenues are measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales taxes and other taxes we collect are recorded as liabilities until remitted and thus are excluded from revenues. Costs to obtain and fulfill contracts (primarily asphalt construction paving contracts) are immaterial and are expensed as incurred when the expected amortization period is one year or less. Our segment total revenues by geographic market for the three and six month periods ended June 30, 2024 and 2023 are disaggregated as follows (the decrease in Gulf Coast market concrete revenues is primarily attributable to the sale of concrete operations in Texas in November 2023; see Note 16 for additional information): Three Months Ended June 30, 2024 in millions Aggregates Asphalt Concrete Total East revenues $ 461.7 $ 63.0 $ 82.4 $ 607.1 Gulf Coast revenues 885.6 64.6 2.5 952.7 West revenues 266.2 223.6 82.4 572.2 Segment sales $ 1,613.5 $ 351.2 $ 167.3 $ 2,132.0 Intersegment sales (117.6) 0.0 0.0 (117.6) Total revenues 1 $ 1,495.9 $ 351.2 $ 167.3 $ 2,014.4 Three Months Ended June 30, 2023 in millions Aggregates Asphalt Concrete Total East revenues $ 451.7 $ 60.8 $ 95.4 $ 607.9 Gulf Coast revenues 879.1 64.5 152.7 1,096.3 West revenues 250.0 212.1 95.4 557.5 Segment sales $ 1,580.8 $ 337.4 $ 343.5 $ 2,261.7 Intersegment sales (148.8) 0.0 0.0 (148.8) Total revenues 1 $ 1,432.0 $ 337.4 $ 343.5 $ 2,112.9 Six Months Ended June 30, 2024 in millions Aggregates Asphalt Concrete Total East revenues $ 800.6 $ 85.7 $ 158.3 $ 1,044.6 Gulf Coast revenues 1,642.0 107.1 4.5 $ 1,753.6 West revenues 462.3 344.6 152.7 $ 959.6 Segment sales $ 2,904.9 $ 537.4 $ 315.5 $ 3,757.8 Intersegment sales (197.7) 0.0 0.0 $ (197.7) Total revenues 1 $ 2,707.2 $ 537.4 $ 315.5 $ 3,560.1 Six Months Ended June 30, 2023 in millions Aggregates Asphalt Concrete Total East revenues $ 795.0 $ 82.5 $ 183.3 $ 1,060.8 Gulf Coast revenues 1,668.1 110.7 288.9 2,067.7 West revenues 414.3 313.9 156.5 884.7 Segment sales $ 2,877.4 $ 507.1 $ 628.7 $ 4,013.2 Intersegment sales (251.4) 0.0 0.0 (251.4) Total revenues 1 $ 2,626.0 $ 507.1 $ 628.7 $ 3,761.8 The geographic markets are defined by states/countries as follows: East market — Arkansas, Delaware, Illinois, Kentucky, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Tennessee, Virginia and Washington D.C. Gulf Coast market — Alabama, Florida, Georgia, Louisiana, Mississippi, Oklahoma, South Carolina, Texas, U.S. Virgin Islands, Freeport (Bahamas), Puerto Cortés (Honduras) and Quintana Roo (Mexico) West market — Arizona, California, Hawaii, New Mexico and British Columbia (Canada) Total revenues are primarily derived from our p roduct sales of aggregates (crushed stone, sand and gravel, sand and other aggregates), asphalt mix and ready-mixed concrete, and include freight & delivery costs that we pass along to our customers to deliver these products. We also generate service revenues from our asphalt construction paving business and service revenues related to our aggregates business, such as landfill tipping fees. Our total service revenues were $70.2 million (3.5% of total revenues) and $69.7 million (3.3% of total revenues) for the three months ended June 30, 2024 and 2023, respectively, and $106.7 million ( 3.0% of total revenues) and $104.8 million (2.8% of total revenues) for the six months ended June 30, 2024 and 2023, respectively. Our products typically are sold to private industry and not directly to governmental entities. Although approximately 40% to 55% of our aggregates shipments have historically been used in publicly funded construction (such as highways, airports and government buildings), a relatively small portion of our sales are made directly to federal, state, county or municipal governments/agencies. Therefore, although reductions in state and federal funding can curtail publicly funded construction, the vast majority of our business is not directly subject to renegotiation of profits or termination of contracts with local, state or federal governments. PRODUCT REVENUES Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs at a point in time when our aggregates, asphalt mix and ready-mixed concrete are shipped/delivered and control passes to the customer. Revenue for our products is recorded at the fixed invoice amount, and payment is due by the 15 th day of the following month. We do not offer discounts for early payment. Freight & delivery generally represents pass-through transportation costs we incur (including our administrative costs) and pay to third-party carriers to deliver our products to customers and are accounted for as a fulfillment activity. Likewise, the costs related to freight & delivery are included in cost of revenues. Freight & delivery revenues are as follows: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Total revenues $ 2,014.4 $ 2,112.9 $ 3,560.1 $ 3,761.8 Freight & delivery revenues 1 (258.5) (264.5) (480.3) (490.4) Total revenues excluding freight & delivery $ 1,755.9 $ 1,848.4 $ 3,079.8 $ 3,271.4 1 Includes freight & delivery to remote distribution sites. CONSTRUCTION PAVING SERVICE REVENUES Revenue from our asphalt construction paving business is recognized over time using the percentage-of-completion method under the cost approach. The percentage of completion is determined by costs incurred to date as a percentage of total costs estimated for the project. Under this approach, recognized contract revenue equals the total estimated contract revenue multiplied by the percentage of completion. Future revenues from unsatisfied performance obligations (including contracts with an expected duration of 1 year or less) at June 30, 2024 and 2023 were $271.6 million and $130.2 million, respectively. The remaining period to complete the obligations at June 30, 2024 ranged from 1 month to 54 months. The increase in future revenues from unsatisfied performance obligations is primarily due to acquisitions completed during the second quarter of 2024 (refer to Note 16 for further information). Our construction contracts are unit priced, and an account receivable is recorded for amounts invoiced based on actual units produced. Contract assets for estimated earnings in excess of billings, contract assets related to retainage provisions and contract liabilities for billings in excess of costs are immaterial. Variable consideration in our construction paving contracts is immaterial and consists of incentives and penalties based on the quality of work performed. Our construction paving contracts may contain warranty provisions covering defects in equipment, materials, design or workmanship that generally run from nine months to one year after project completion. Due to the nature of our construction paving projects, including contract owner inspections of the work during construction and prior to acceptance, we have not experienced material warranty costs for these short-term warranties. VOLUMETRIC PRODUCTION PAYMENT DEFERRED REVENUES In 2013 and 2012, we sold a percentage interest in certain future aggregates production for net cash proceeds of $226.9 million. These transactions, structured as volumetric production payments (VPPs): ▪ relate to eight quarries in Georgia and South Carolina ▪ provide the purchaser solely with a nonoperating percentage interest in the subject quarries’ future aggregates production ▪ contain no minimum annual or cumulative guarantees by us for production or sales volume, nor minimum sales price ▪ are both volume and time limited (we expect the transactions will last approximately 20 more years, limited by volume rather than time) We are the exclusive sales agent for, and transmit quarterly to the purchaser the proceeds from the sale of, the purchaser’s share of aggregates production. Our consolidated total revenues exclude the revenue from the sale of the purchaser’s share of aggregates. The proceeds we received from the sale of the percentage interest were recorded as deferred revenue on the balance sheet. We recognize revenue on a unit-of-sales basis (as we sell the purchaser’s share of production) relative to the volume limitations of the transactions. Given the nature of the risks and potential rewards assumed by the buyer, the transactions do not reflect financing activities. Changes in our deferred revenue balances (current and noncurrent) are as follows: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Deferred revenue balance at beginning of period $ 151.1 $ 159.8 $ 152.8 $ 161.8 Revenue recognized from deferred revenue (2.2) (2.4) (3.9) (4.4) Deferred revenue balance at end of period $ 148.9 $ 157.4 $ 148.9 $ 157.4 Based on expected sales from the specified quarries, we expect to recognize $7.5 million of VPP deferred revenue as income during the twelve-month period ending June 30, 2025 (reflected in other current liabilities in our June 30, 2024 Condensed Consolidated Balance Sheet).

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as described below: Level 1: Quoted prices in active markets for identical assets or liabilities Level 2: Inputs that are derived principally from or corroborated by observable market data Level 3: Inputs that are unobservable and significant to the overall fair value measurement Our assets subject to fair value measurement on a recurring basis are summarized below: in millions June 30 December 31 June 30 Level 1 Fair Value Rabbi Trust Mutual funds $ 31.5 $ 31.7 $ 29.7 Total $ 31.5 $ 31.7 $ 29.7 Level 2 Fair Value Interest rate swaps $ 0.0 $ (0.3) $ (2.0) Rabbi Trust Money market mutual fund 0.8 0.5 0.8 Total $ 0.8 $ 0.2 $ (1.2) We have two Rabbi Trusts for the purpose of providing a level of security for the employee nonqualified retirement and deferred compensation plans and for the directors' nonqualified deferred compensation plans. The fair values of these investments are estimated using a market approach. The Level 1 investments include mutual funds for which quoted prices in active markets are available. Level 2 investments are stated at estimated fair value based on the underlying investments in the fund (high-quality, short-term, U.S. dollar-denominated money market instruments). Net gains of the Rabbi Trusts’ investments were $1.0 million and $2.0 million for the six months ended June 30, 2024 and 2023, respectively. The portions of the net gains related to investments still held by the Rabbi Trusts at June 30, 2024 and 2023 were $0.9 million and $2.1 million, respectively. Interest rate swaps are measured at fair value using quoted market prices or pricing models that use prevailing market interest rates as of the measurement date. These interest rate swaps are more fully described in Note 6. The carrying values of our cash equivalents, restricted cash, accounts and notes receivable, short-term debt, trade payables and accruals, and all other current liabilities approximate their fair values because of the short-term nature of these instruments. Additional disclosures for derivative instruments and interest-bearing debt are presented in Notes 6 and 7, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS During the normal course of operations, we are exposed to market risks including interest rates, foreign currency exchange rates and commodity prices. From time to time, we use derivative instruments to balance the cost and risk of such expenses. We do not use derivative instruments for trading or other speculative purposes. In March 2023, we issued $550.0 million of 5.80% fixed-rate debt maturing in March 2026. Concurrently, we entered into fixed-to-floating interest rate swap agreements designated as fair value hedges in the amount of $550.0 million. Under these swap agreements, we received a fixed interest rate of 5.80% (matches the fixed rate we paid on the $550.0 million of debt) and paid daily compound Secured Overnight Financing Rate (SOFR) plus 0.241%. These swap agreements terminated in March 2024, coinciding with the redemption of the debt. The changes in the fair value of these swaps designated as fair value hedges were recorded in interest expense and were perfectly offset by changes in the fair value of the related debt also recorded in interest expense. These swaps were recognized at fair value in the accompanying Condensed Consolidated Balance Sheets as follows: in millions Balance Sheet Location June 30 December 31 June 30 Fair Value Hedges 1 Interest rate swaps Other current/noncurrent assets $ 0.0 $ 3.9 $ 5.1 Interest rate swaps Other current/noncurrent liabilities 0.0 (4.2) (7.1) Interest rate swaps net liability $ 0.0 $ (0.3) $ (2.0) 1 See Note 5 for further discussion of fair value determination. In 2007, 2018 and 2020, we entered into interest rate locks of future debt issuances to hedge the risk of higher interest rates. These interest rate locks were designated as cash flow hedges. The gain/loss upon settlement of these cash flow hedges is deferred (recorded in accumulated other comprehensive income (AOCI)) and amortized to interest expense over the term of the related debt. This amortization was reflected in the accompanying Condensed Consolidated Statements of Comprehensive Income as follows: in millions Income Statement Three Months Ended Six Months Ended 2024 2023 2024 2023 Cash Flow Hedges Loss reclassified from AOCI Interest expense $ (0.6) $ (0.5) $ (1.1) $ (1.1) For the twelve-month period ending June 30, 2025, we estimate that $2.3 million of the $18.6 million net of tax loss in AOCI will be reclassified to interest expense.

Discounts and debt issuance costs are amortized using the effective interest method over the terms of the respective notes resulting in $4.5 million and $3.7 million of net interest expense for these items for the six months ended June 30, 2024 and 2023, respectively. DELAYED DRAW TERM LOAN, LINE OF CREDIT AND COMMERCIAL PAPER PROGRAM In June 2021, we entered into a $1,600.0 million unsecured delayed draw term loan which was fully drawn in August 2021 upon the acquisition of U.S. Concrete. The delayed draw term loan was paid down to $1,100.0 million in September 2021 with cash on hand, paid down to $550.0 million in August 2022 using the proceeds from the issuance of commercial paper as described below and fully repaid in March 2023 using proceeds from the issuance of 5.80% senior notes as described below. In 2022, we established a $1,600.0 million commercial paper program through which we borrowed $550.0 million that was used to partially repay the delayed draw term loan. As of June 30, 2024, we had $95.0 million in short-term commercial paper borrowings and $550.0 million in long-term commercial paper borrowings. Commercial paper borrowings bear interest at rates determined at the time of borrowing and as agreed between us and the commercial paper investors. Our $1,600.0 million unsecured line of credit matures in August 2027 and contains covenants customary for an unsecured investment-grade facility. As of June 30, 2024, we were in compliance with the covenants. Borrowings on the line of credit bear interest, at our option, at either SOFR plus a margin or Truist Bank’s base rate plus a margin. The margins are determined by our credit ratings. Standby letters of credit, which are issued under the line of credit and reduce availability, are charged a fee equal to the margin for SOFR borrowings plus 0.175%. We also pay a commitment fee on the daily average unused amount of the line of credit that ranges from 0.090% to 0.225% determined by our credit ratings. As of June 30, 2024, the margin for SOFR borrowings was 1.125%, the margin for base rate borrowings was 0.125% and the commitment fee for the unused amount was 0.100%. As of June 30, 2024, our available borrowing capacity under the line of credit was $1,504.8 million. Utilization of the borrowing capacity was as follows: ▪ None was borrowed ▪ $95.2 million was used to support standby letters of credit TERM DEBT All of our $3,486.1 million (face value) of term debt (which includes $645.0 million of commercial paper) is unsecured. All of the covenants in the debt agreements are customary for investment-grade facilities. As of June 30, 2024, we were in compliance with all term debt covenants. In March 2023, we issued $550.0 million of 5.80% senior notes due 2026. Total proceeds of $546.6 million (net of discounts and transaction costs), together with cash on hand, were used to repay the $550.0 million delayed draw term loan. We redeemed these notes at par in March 2024 using cash on hand and recognized noncash expense of $2.3 million with the acceleration of unamortized deferred debt issuance costs. STANDBY LETTERS OF CREDIT We provide, in the normal course of business, certain third-party beneficiaries with standby letters of credit to support our obligations to pay or perform according to the requirements of an underlying agreement. Such letters of credit typically have an initial term of one year, renew automatically and can only be modified or canceled with the approval of the beneficiary. Our standby letters of credit are issued by banks that participate in our $1,600.0 million line of credit and reduce the borrowing capacity thereunder. Our standby letters of credit as of June 30, 2024 are summarized by purpose in the table below: in millions Risk management insurance $ 80.3 Reclamation/restoration requirements 14.9 Total standby letters of credit $ 95.2

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Certain of our aggregates reserves are burdened by volumetric production payments (nonoperating interest) as described in Note 4. As the holder of the operating interest, we have responsibility to bear the cost of mining and producing the reserves attributable to this nonoperating interest. As stated in Note 2, our lease liabilities totaled $580.7 million as of June 30, 2024. As summarized by purpose in Note 7, our standby letters of credit totaled $95.2 million as of June 30, 2024. As described in Note 9, our asset retirement obligations totaled $334.1 million as of June 30, 2024. LITIGATION AND ENVIRONMENTAL MATTERS We are subject to occasional governmental proceedings and orders pertaining to occupational safety and health or to protection of the environment, such as proceedings or orders relating to noise abatement, air emissions or water discharges. As part of our continuing program of stewardship in safety, health and environmental matters, we have been able to resolve such proceedings and to comply with such orders without any material adverse effects on our business. We have received notices from the United States Environmental Protection Agency (EPA) or similar state or local agencies that we are considered a potentially responsible party (PRP) at a limited number of sites under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund) or similar state and local environmental laws. Generally, we share the cost of remediation at these sites with other PRPs or alleged PRPs in accordance with negotiated or prescribed allocations. There is inherent uncertainty in determining the potential cost of remediating a given site and in determining any individual party's share in that cost. As a result, estimates can change substantially as additional information becomes available regarding the nature or extent of site contamination, remediation methods, other PRPs and their probable level of involvement, and actions by or against governmental agencies or private parties. We have reviewed the nature and extent of our involvement at each Superfund site, as well as potential obligations arising under other federal, state and local environmental laws. While ultimate resolution and financial liability is uncertain at a number of the sites, in our opinion, based on information currently available, the ultimate resolution of claims and assessments related to these sites will not have a material effect on our consolidated results of operations, financial position or cash flows, although amounts recorded in a given period could be material to our results of operations or cash flows for that period. Amounts accrued for environmental matters (measured on an undiscounted basis) are presented below: in millions June 30 December 31 June 30 Continuing operations $ 33.7 $ 32.6 $ 32.8 Retained from former Chemicals business 8.3 8.3 8.3 Total accrued environmental remediation costs $ 42.0 $ 40.9 $ 41.1 We are a defendant in various lawsuits in the ordinary course of business. It is not possible to determine with precision the outcome, or the amount of liability, if any, under these lawsuits, especially where the cases involve possible jury trials with as yet undetermined jury panels. In addition to these lawsuits in which we are involved in the ordinary course of business, certain other material legal proceedings are more specifically described below: ▪ LOWER PASSAIC RIVER STUDY AREA (DISCONTINUED OPERATIONS and SUPERFUND SITE) — The Lower Passaic River Study Area is part of the Diamond Shamrock Superfund Site in New Jersey. Vulcan and approximately 70 other companies are parties (collectively the Cooperating Parties Group, CPG) to a May 2007 Administrative Order on Consent (AOC) with the EPA to perform a Remedial Investigation/Feasibility Study (draft RI/FS) of the lower 17 miles of the Passaic River (River). The draft RI/FS was submitted recommending a targeted hot spot remedy; however, the EPA issued a record of decision (ROD) in March 2016 that calls for a bank-to-bank dredging remedy for the lower 8 miles of the River. The EPA estimates that the cost of implementing this proposal is $1.38 billion. In September 2016, the EPA entered into an Administrative Settlement Agreement and Order on Consent with Occidental Chemical Corporation (Occidental) in which Occidental agreed to undertake the remedial design for this bank-to-bank dredging remedy and to reimburse the United States for certain response costs. Efforts to investigate and remediate the River have been underway for many years and have involved hundreds of entities that have had operations on or near the River at some point during the past several decades. We formerly owned a chemicals operation near the mouth of the River, which was sold in 1974. The major risk drivers in the River have been identified to include dioxins, PCBs, DDx and mercury. We did not manufacture any of these risk drivers and have no evidence that any of these were discharged into the River by Vulcan. In August 2017, the EPA informed certain members of the CPG, including Vulcan and others, that it planned to use the services of a third-party allocator with the expectation of offering cash-out settlements to some parties in connection with the bank-to-bank remedy identified in the ROD. This voluntary allocation process established an impartial third-party expert recommendation for use by the government and the participants as the basis of possible settlements, including settlements related to future remediation actions. The final allocation recommendations, which are subject to confidentiality provisions, were submitted to the EPA for its review and consideration in late December 2020. Certain PRPs, including Vulcan, thereafter received a joint confidential settlement demand from the EPA/Department of Justice (DOJ). Vulcan and certain of the other PRPs that received the joint confidential settlement demand (the Settling Defendants) reached an agreement to settle with the EPA/DOJ and negotiated a Consent Decree. The Consent Decree has been lodged with the court. Vulcan’s portion of the settlement is within the immaterial loss recorded for this matter in 2015. In July 2018, Vulcan, along with more than 100 other defendants, was sued by Occidental in United States District Court for the District of New Jersey, Newark Vicinage. Occidental is seeking cost recovery and contribution under CERCLA for costs related to the River. This lawsuit is currently stayed pending adjudication of the Consent Decree. In another related proceeding, Occidental filed a lawsuit in March 2023 against Vulcan and 39 other defendants in United States District Court for the District of New Jersey, Newark Vicinage seeking cost recovery and contribution under CERCLA for costs related to the upper 9 miles of the River. It is unknown at this time how the settlement and approval of the Consent Decree with the EPA/DOJ would affect the Occidental lawsuits. ▪ TEXAS BRINE MATTER (DISCONTINUED OPERATIONS) — During operation of its former Chemicals Division, Vulcan leased the right to mine salt out of an underground salt dome formation in Assumption Parish, Louisiana from 1976 - 2005. Throughout that period, Texas Brine Company (Texas Brine) was the operator contracted by Vulcan to mine and deliver the salt as brine. We sold our Chemicals Division in 2005 and transferred our rights and interests related to the salt and mining operations to the purchaser, a subsidiary of Occidental Chemical Company (Occidental), and we have had no association with the leased premises or Texas Brine since that time. In August 2012, a sinkhole developed in the vicinity of the Texas Brine mining operations. Numerous lawsuits were filed thereafter in state court in Assumption Parish, Louisiana. Other lawsuits, including class action litigation, were filed in the United States District Court for the Eastern District of Louisiana in New Orleans. In these lawsuits, the main plaintiffs sued numerous defendants, including Texas Brine, Occidental and Vulcan, alleging various damages including, but not limited to, property damages; a claim by the State of Louisiana for response costs and civil penalties; physical damages to oil and gas pipelines and storage facilities (pipelines); and business interruption losses. All such claims have been settled except for the claims by the State of Louisiana. Our insurers to date have funded these settlements in excess of our self-insured retention amount. Additionally, Texas Brine, Occidental and Vulcan sued each other in various state and federal court forums. Vulcan and Occidental have since dismissed all of their claims against one another; Texas Brine’s and Occidental’s claims against each other are pending in arbitration; and Texas Brine’s and Vulcan’s claims against each other are pending in state and federal court. In general, Texas Brine alleges that the sinkhole was caused, in whole or in part, by our negligent or fraudulent actions or failure to act; that we breached the salt lease with Occidental, as well as an operating agreement and related contracts with Texas Brine; that we were strictly liable for certain property damages in our capacity as a former lessee of the salt lease; and that we violated the agreement under which we sold our Chemicals Division to Occidental. Texas Brine’s claims against Vulcan include claims for past and future response costs, lost profits and investment costs, indemnity payments, attorneys’ fees, other litigation costs, and judicial interests. Texas Brine also recently filed a lawsuit against Vulcan seeking indemnity for potential exposure Texas Brine may have to Occidental in the related arbitration, the State of Louisiana, and for ongoing and future Louisiana regulatory matters. In August 2022, we removed the lawsuit to federal court. The state court held a joint bench trial (judge only) in 2017 in three cases brought by pipeline companies claiming damages to their facilities as a result of the sinkhole. This “Phase 1” trial was limited in scope to comparative fault and liability for causing the sinkhole. In December 2017, the trial court issued a ruling allocating fault as follows: Occidental 50%, Texas Brine (and its wholly-owned subsidiary) 35% and Vulcan 15%. In December 2020, the Louisiana Court of Appeal, First Circuit reversed the judgment in part in one of the three jointly tried cases, allocating 55% of the fault to Texas Brine (and its wholly-owned subsidiary); 30% to Occidental; and affirming the 15% fault allocation to Vulcan. In May 2021 and April 2022, the Court of Appeal issued judgments in the other two pipeline cases, adopting the same fault allocation. The Louisiana Supreme Court has declined to review the judgments, resulting in final judgments regarding fault allocations in those matters. In the second quarter of 2022, we recorded an immaterial loss related to the claims brought by Texas Brine. In August 2022, Vulcan and Texas Brine commenced a joint “Phase 2” bench trial in the same three pipeline cases where fault was allocated. Prior to trial, the trial court granted various motions by Vulcan seeking dismissal of Texas Brine’s contract-based claims and hundreds of millions of dollars in alleged damages. Thus, the Phase 2 trial addressed the claims that remained pending between Texas Brine and Vulcan after that motion practice. During the Phase 2 trial, Texas Brine and Vulcan reached a negotiated joint stipulation as to the amount of Texas Brine’s damages for its surviving tort claims at issue in the trial. After applying Vulcan’s 15% fault allocation, Vulcan’s stipulated financial responsibility for the damages at issue in the trial is within the immaterial loss recorded during the second quarter of 2022. I n December 2022, the trial court entered a judgment in the pipeline cases reflecting this stipulation. Texas Brine moved to assess all trial costs against Vulcan. Texas Brine and Vulcan thereafter reached a settlement, wherein Vulcan agreed to pay a portion of Texas Brine's trial costs, the amount of which was within the remaining immaterial loss recorded in the second quarter of 2022. The December 2022 Phase 2 judgment did not address numerous of Texas Brine’s claims seeking hundreds of millions of dollars in damages that were dismissed prior to trial. Texas Brine has appealed those judgments. We cannot at this time reasonably estimate the range of liability, if any, that could result if an appellate court reverses any of the trial court’s decisions. At this time, we also cannot reasonably estimate a range of liability pertaining to the claims brought by the State of Louisiana. ▪ NEW YORK WATER DISTRICT CASES AND NEW JERSEY NATURAL RESOURCE DAMAGES CASE (DISCONTINUED OPERATIONS) — During the operation of our former Chemicals Division, which was divested to Occidental in 2005, Vulcan manufactured a chlorinated solvent known as 1,1,1-trichloroethane (TCA). We are a defendant in 29 cases allegedly involving TCA. We are a defendant in 28 cases brought by New York water providers, and in one case brought by the State of New Jersey, all involving TCA stabilized with 1,4-dioxane. The cases in New York are filed in the United States District Court for the Eastern District of New York. According to the various complaints, the plaintiff-water providers serve customers in a number of New York counties (Nassau, Suffolk, Orange, Putnam, Sullivan, Ulster, Washington and Westchester) and seek unspecified compensatory damages associated with the remediation of water wells allegedly contaminated with 1,4-dioxane. They are also seeking punitive damages. The New Jersey case, filed in state court in Mercer County (Trenton) in March 2023, seeks recovery for the entire State of New Jersey based on alleged damages to surface water, ground water and other natural resources. In the New Jersey case, the plaintiff seeks unspecified compensatory damages to restore the allegedly contaminated natural resources to a condition with zero 1,4-dioxane. The plaintiff also seeks disgorgement of profits from the sale of TCA in New Jersey, as well as penalties and attorneys’ fees under various New Jersey statutes. We will vigorously defend these cases on substantive and procedural grounds. At this time, we cannot determine the likelihood of loss, or reasonably estimate a range of loss, if any, pertaining to the above-referenced cases. ▪ HEWITT LANDFILL MATTER (SUPERFUND SITE) — In September 2015, the Los Angeles Regional Water Quality Control Board (RWQCB) issued a Cleanup and Abatement Order directing Calmat Co., a Vulcan subsidiary (hereinafter "Vulcan") to assess, monitor, cleanup, and abate wastes that have been discharged to soil, soil vapor, and/or groundwater at the former Hewitt Landfill in Los Angeles. Following an onsite and offsite investigation and pilot scale testing, the RWQCB approved a corrective action that includes leachate recovery, storm water capture and conveyance improvements, and a groundwater pump, treat and reinjection system. Certain on-site source control measures have been implemented, and the new treatment system is fully operational. Currently-anticipated costs of these on-site source control activities have been fully accrued. We are also engaged in an ongoing dialogue with the EPA, Honeywell, and the Los Angeles Department of Water and Power (LADWP) regarding the potential contribution of the Hewitt Landfill to groundwater contamination in the North Hollywood Operable Unit (NHOU) of the San Fernando Valley Superfund Site. The EPA and Vulcan entered into an AOC and Statement of Work having an effective date of September 2017 for the design of two extraction wells south of the Hewitt Landfill to protect the North Hollywood West (NHW) well field located within the NHOU. In November 2017, we submitted a Pre-Design Investigation (PDI) Work Plan to the EPA, which sets forth the activities and schedule for collection of data in support of our evaluation of the need for an offsite remedy. In addition, this evaluation was expanded as part of the PDI to include the evaluation of a remedy in light of LADWP’s Rinaldi-Toluca (RT) wellfield project. PDI investigative activities were completed between the first and third quarters of 2018, and in December 2018 we submitted a Draft PDI Evaluation Report to the EPA. The Draft PDI Evaluation Report summarizes data collection activities conducted pursuant to the Draft PDI Work Plan and provides model updates and evaluation of remediation alternatives for offsite areas. The EPA provided a final set of comments to the Draft PDI Evaluation Report in October 2020. The final set of comments included a request that Vulcan revise and develop a final PDI Evaluation Report. The final comments further provided a proposal for an alternative approach for offsite remediation (as opposed to installation of offsite extraction wells) and development of a Supplemental PDI Evaluation Report (Supplemental Report) that would require the EPA to modify the remedy in the record of decision as it relates to the Hewitt Landfill. In December 2020, we submitted the Final PDI Evaluation Report, which included responses to the EPA’s comments. At the EPA's request, we submitted a Supplemental Report in March 2023 and an Alternative Design Work Plan (ADWP) in May 2023. Similar to the PDI Evaluation Report, the Supplemental Report and ADWP identified expansion of the onsite Hewitt remedy in conjunction with the offsite treatment being performed by LADWP as the preferred option for addressing contamination in offsite areas, instead of the two wells proposed by the EPA. In conjunction with its review of the Supplemental Report, the EPA held an initial meeting with stakeholders, including LADWP, in November 2023 and has requested additional meetings to determine a path forward. In December 2019, Honeywell agreed with LADWP to build a water treatment system (often referred to as the Cooperative Containment Concept or CCC or the second interim remedy) that will provide treated groundwater in the NHOU to LADWP for public water supply purposes. Honeywell contends that some of the contamination to be remediated by the treatment system it is building originated from the Hewitt Landfill and that Vulcan should fund some portion of the costs that Honeywell has incurred and will incur in developing and implementing the second interim remedy. During the fourth quarter of 2021, we completed a partial settlement with Honeywell related to certain of the costs that Honeywell has incurred for an immaterial amount. In March 2023, Honeywell filed a lawsuit against Vulcan and a third party alleging that Honeywell has incurred more than $11 million in costs to resolve its liability to the EPA and that it estimates that it will spend in excess of $100 million to construct and operate its water treatment system. Honeywell seeks an "equitable share of necessary response costs" from the defendants. Discussions are ongoing with Honeywell regarding the reasonable costs Honeywell has incurred. We are also gathering and analyzing data and developing technical information to determine the extent of possible contribution by the Hewitt Landfill to the groundwater contamination in the area. Based on this technical information, we have accrued an immaterial amount for our contribution of costs anticipated to be incurred by Honeywell. This work is also intended to assist in identification of other PRPs that may have contributed to groundwater contamination in the area. Further, LADWP is constructing two new production and treatment facilities at city wellfields located near the Hewitt Landfill — the NHW wellfield and the RT wellfield (also referred to as the NHW treatment system and North Hollywood Central (NHC) treatment system, respectively). LADWP has alleged that the Hewitt Landfill is one of the primary sources of contamination at the NHW treatment system and one of the sources of contamination at the NHC treatment system. According to information available on the California State Water Resources Control Board (SWRCB) website, the capital cost of the NHW treatment system is estimated at $92 million, and the capital cost of the NHC treatment system is estimated at $245 million. The systems are expected to commence operations in 2024 for NHW and 2025 for NHC and will thereafter incur costs for operation and maintenance. LADWP has applied for and received substantial funding to contribute to both treatment systems from grants of Proposition 1 bond funding from the SWRCB. According to information available on the SWRCB website, the bond money obtained for the NHW treatment system is $46 million, and the bond money obtained for the NHC treatment system is $95 million. We anticipate continued discussions with LADWP regarding its potential claims. In conjunction with those discussions, we are engaging in further efforts to gather and analyze records and data in order to assess the extent of possible contribution by the Hewitt Landfill to the groundwater contamination in the area, consistent with the parallel request by the EPA, and the reasonableness of LADWP’s remediation efforts. This work is also intended to assist in identification of other PRPs that may have contributed to groundwater contamination in the area of the NHW and RT wellfields. Together, these efforts will allow us to analyze our anticipated equitable contribution to LADWP’s remediation efforts. Among other factors, we anticipate that any equitable contribution should take into account the on-site source control and other measures implemented by Vulcan at the former Hewitt Landfill, the relative contribution and duration of any contaminants originating from the Hewitt Landfill to the LADWP systems, and the cost effectiveness of the LADWP systems. At this time, we cannot reasonably estimate a range of a loss to Vulcan pertaining to LADWP’s potential contribution claim. ▪ NAFTA ARBITRATION — In September 2018, our subsidiary Legacy Vulcan, LLC (Legacy Vulcan), on its own behalf, and on behalf of our Mexican subsidiary Calizas Industriales del Carmen, S.A. de C.V. (Calica), served the United Mexican States (Mexico) a Notice of Intent to Submit a Claim to Arbitration under Chapter 11 of the North American Free Trade Agreement (NAFTA). This NAFTA claim relates to the treatment of a portion of our quarrying operations in Quintana Roo, Mexico arising from, among other measures, Mexico’s failure to comply with a legally binding zoning agreement and relates to other unfair, arbitrary and capricious actions by Mexico’s environmental enforcement agency. We assert that these actions are in breach of Mexico’s international obligations under NAFTA and international law. As required by Article 1118 of NAFTA, we sought to settle this dispute with Mexico through consultations. Notwithstanding our good faith efforts to resolve the dispute amicably, we were unable to do so and filed a Request for Arbitration with the International Centre for Settlement of Investment Disputes (ICSID) in December 2018. In January 2019, ICSID registered our Request for Arbitration. A hearing on the merits took place in July 2021. While we awaited the final resolution from the tribunal, we continued to engage with government officials to pursue an amicable resolution of the dispute. On May 5, 2022, Mexican government officials unexpectedly and arbitrarily shut down Calica’s remaining operations in Mexico. On May 8, 2022, Legacy Vulcan filed an application in the NAFTA arbitration seeking provisional measures and leave to file an ancillary claim in connection with this latest shutdown (see Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Known Trends or Uncertainties). In July 2022, the NAFTA arbitration tribunal granted Legacy Vulcan’s application and ordered Mexico not to take any action that might further aggravate the dispute between the parties or render the resolution of the dispute potentially more difficult. A hearing on the merits of the ancillary claim took place in August 2023. We expect that the NAFTA arbitration tribunal will issue a decision on the claim and ancillary claim during 2024. At this time, there can be no assurance whether we will be successful in our NAFTA claim and ancillary claim, and we cannot quantify the amount we may recover, if any, under this arbitration proceeding if we are successful. It is not possible to predict the ultimate outcome of these and other legal proceedings in which we are involved, and a number of factors, including developments in ongoing discovery or adverse rulings, or the verdict of a particular jury, could cause actual losses to differ materially from accrued costs. No liability was recorded for claims and litigation for which a loss was determined to be only reasonably possible or for which a loss could not be reasonably estimated. Legal costs incurred in defense of lawsuits are expensed as incurred. In addition, losses on certain claims and litigation described above may be subject to limitations on a per occurrence basis by excess insurance, as described in our most recent Annual Report on Form 10-K.

Asset Retirement Obligation Disclosure [Abstract]
ASSET RETIREMENT OBLIGATIONS	ASSET RETIREMENT OBLIGATIONS Asset retirement obligations (AROs) are legal obligations associated with the retirement of long-lived assets resulting from the acquisition, construction, development and/or normal use of the underlying assets, including legal obligations for land reclamation. Recognition of a liability for an ARO is required in the period in which it is incurred at its estimated fair value. The associated asset retirement costs are capitalized as part of the carrying amount of the underlying asset and depreciated over the estimated useful life of the asset. The liability is accreted through charges to operating expenses. If the ARO is settled for a value other than the carrying amount of the liability, we recognize a gain or loss on settlement. ARO operating costs related to accretion of the liabilities and depreciation of the assets are as follows: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Accretion $ 3.6 $ 3.4 $ 7.1 $ 6.9 Depreciation 2.8 2.2 5.2 4.3 Total ARO operating costs $ 6.4 $ 5.6 $ 12.3 $ 11.2 ARO operating costs are reported in cost of revenues.

Retirement Benefits [Abstract]
BENEFIT PLANS	BENEFIT PLANS PENSION PLANS We sponsor two qualified, noncontributory defined benefit pension plans, the Vulcan Materials Company Pension Plan (VMC Pension Plan) and the CMG Hourly Pension Plan (CMG Pension Plan). The VMC Pension Plan has been closed to new entrants since 2007, and benefit accruals ceased in 2005 for hourly participants and in 2013 for salaried participants. The CMG Pension Plan is closed to new entrants other than through one small union, and benefits continue to accrue equal to a flat dollar amount for each year of service. In addition to these qualified plans, we sponsor three unfunded, nonqualified pension plans. The following table sets forth the components of net periodic pension benefit cost: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Service cost $ 0.7 $ 0.6 $ 1.4 $ 1.3 Interest cost 8.2 8.5 16.4 17.0 Expected return on plan assets (7.1) (6.9) (14.1) (13.8) Amortization of prior service cost 0.3 0.4 0.5 0.7 Amortization of actuarial loss 1.2 1.4 2.5 2.8 Net periodic pension benefit cost $ 3.3 $ 4.0 $ 6.7 $ 7.9 Pretax reclassifications from AOCI included in net periodic pension benefit cost $ 1.5 $ 1.8 $ 3.0 $ 3.5 The contributions to pension plans for the six months ended June 30, 2024 and 2023, as reflected on the Condensed Consolidated Statements of Cash Flows, pertain to benefit payments under nonqualified plans for both periods. POSTRETIREMENT PLANS In addition to pension benefits, we provide certain healthcare and life insurance benefits for some retired employees. Substantially all of our salaried employees and, where applicable, certain of our hourly employees may become eligible for these benefits if they reach a qualifying age and meet certain service requirements. Generally, Company-provided healthcare benefits end when covered individuals become eligible for Medicare benefits, become eligible for other group insurance coverage or reach age 65, whichever occurs first. The following table sets forth the components of net periodic other postretirement benefit cost: Three Months Ended Six Months Ended in millions 2024 2023 2024 2023 Service cost $ 0.6 $ 0.5 $ 1.2 $ 1.0 Interest cost 0.5 0.5 1.1 1.0 Amortization of prior service cost 0.4 0.4 0.7 0.7 Amortization of actuarial gain (0.2) (0.4) (0.4) (0.8) Net periodic postretirement benefit cost $ 1.3 $ 1.0 $ 2.6 $ 1.9 Pretax reclassifications from AOCI included in net periodic postretirement benefit cost (credit) $ 0.2 $ 0.0 $ 0.3 $ (0.1) DEFINED CONTRIBUTION PLANS In addition to our pension and postretirement plans, we sponsor four defined contribution plans. Substantially all salaried and non-union hourly employees are eligible to be covered by one of these plans. Under these plans, we match employees’ eligible contributions at established rates. Expense recognized in connection with these matching obligations totaled $48.1 million and $41.1 million for the six months ended June 30, 2024 and 2023, respectively.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING Our operating segments are based on our internal management reporting structure. We continually assess our internal management reporting structure and the financial information evaluated by our Chief Operating Decision Maker (CODM) to determine whether any changes have occurred that would impact segment reporting. During the first quarter of 2024, we reorganized the financial information provided to our CODM to allocate resources and evaluate operating performance. As a result, we report our calcium operation within our Aggregates reporting segment to align with our new reporting structure. All prior period segment information has been revised to conform to the current presentation. This change in our reporting segments had no impact on previously reported consolidated financial results. We have three operating (and reportable) segments organized around our principal product lines: Aggregates, Asphalt and Concrete. The vast majority of our activities are domestic. We sell a relatively small amount of construction aggregates outside the United States. Our Asphalt and Concrete segments are primarily supplied with their aggregates requirements from our Aggregates segment. These intersegment sales are made at local market prices for the particular grade and quality of product used in the production of asphalt mix and ready-mixed concrete and are excluded from total revenues. Management reviews earnings from these reporting segments principally at the gross profit level.

GOODWILL	GOODWILL Goodwill is recognized when the consideration paid for a business exceeds the fair value of the tangible and identifiable intangible assets acquired. Goodwill is allocated to reporting units for purposes of testing goodwill for impairment. We test goodwill for impairment on an annual basis or more frequently if events or circumstances change in a manner that would more likely than not reduce the fair value of a reporting unit below its carrying value. There were no charges for goodwill impairment in the six-month periods ended June 30, 2024 and 2023. Accumulated goodwill impairment losses amount to $303.6 million ($252.7 million in our former Cement segment and $50.9 million in our Concrete segment).

None of these acquisitions were material to our results of operations either individually or collectively, and acquisition related expenses were immaterial. The fair value of consideration transferred for these 2024 acquisitions and the preliminary amounts (pending final appraisals of intangible assets and property, plant & equipment) of assets acquired and liabilities assumed are summarized below: in millions Fair Value of Purchase Consideration Cash $ 193.4 Total fair value of purchase consideration $ 193.4 Identifiable Assets Acquired and Liabilities Assumed Accounts and notes receivable, net $ 8.1 Inventories 7.1 Property, plant & equipment 149.9 Intangible assets Contractual rights in place 30.8 Other liabilities assumed (7.4) Net identifiable assets acquired $ 188.5 Goodwill $ 4.9 As a result of the 2024 acquisitions, we recognized $30.8 million of amortizable intangible assets and $4.9 million of goodwill. The amortizable intangible assets will be amortized against earnings over a weighted-average of 15 years and will be deductible for income tax purposes over 15 years. The $4.9 million of goodwill recognized represents synergies expected to be realized from acquiring an established business with assets that have been assembled over a long period of time; the collection of those assets combined with our assets can earn a higher rate of return than either individually. All of the goodwill recognized will be deductible for income tax purposes. 2023 BUSINESS ACQUISITIONS — For the full year 2023, we completed no business acquisitions. DIVESTITURES AND PENDING DIVESTITURES We had no significant divestitures through the three months ended June 30, 2024. In 2023, we sold: ▪ Fourth quarter – concrete operations in Texas resulting in a third quarter impairment charge of $28.3 million and a fourth quarter loss on sale of $13.8 million (the assets were written down to fair value less cost to sell in the third quarter) ▪ Fourth quarter – excess real estate in Virginia resulting in a pretax gain of $65.7 million ▪ Second quarter – real estate associated with a former recycled concrete facility in Illinois resulting in a pretax gain of $15.2 million No material assets met the criteria for held for sale at June 30, 2024 , December 31, 2023 or June 30, 2023.

The new standard is effective for fiscal years beginning after December 15, 2023 and is to be applied retrospectively. We expect to include cost of revenues in our reportable segment disclosures beginning with our Form 10-K for the year ended December 31, 2024 and continue to assess the effects of other provisions of this ASU. In December 2023, the FASB issued ASU 2023-09, “Income Taxes – Improvements to Income Tax Disclosures,” which requires disclosure of specific categories and disaggregation of information in the rate reconciliation table and expands disclosures related to income taxes paid. The new standard is effective for fiscal years beginning after December 15, 2024 and is to be applied prospectively. Disclosures required by this ASU will be included in our Form 10-K for the year ended December 31, 2025.

Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Our accompanying unaudited condensed consolidated financial statements were prepared in compliance with the instructions to Form 10-Q and Article 10 of Regulation S-X and thus do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements. We prepared the accompanying condensed consolidated financial statements on the same basis as our annual financial statements, except for the adoption of new accounting standards, if any, as described in Note 17. Our Condensed Consolidated Balance Sheet as of December 31, 2023 was derived from the audited financial statement, but it does not include all disclosures required by GAAP. In the opinion of our management, the statements reflect all adjustments, including those of a normal recurring nature, necessary to present fairly the results of the reported interim periods. For further information, refer to the consolidated financial statements and footnotes included in our most recent Annual Report on Form 10-K. Operating results for the three and six month periods ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. Our condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets, liabilities, revenues and expenses. The most significant estimates and assumptions included in the preparation of these financial statements are related to goodwill and long-lived asset impairments, business combinations and purchase price allocation, pension and other postretirement benefits, environmental compliance, claims and litigation including self-insurance, and income taxes (refer to the Critical Accounting Policies included in Item 7 of our most recent Annual Report on Form 10-K). Events that relate to conditions arising after June 30, 2024 will be reflected in management’s estimates for future periods.
NONCONTROLLING INTEREST	NONCONTROLLING INTEREST
RESTRICTED CASH	RESTRICTED CASH Restricted cash primarily consists of cash proceeds from the sale of property held in escrow for the acquisition of replacement property under like-kind exchange agreements. The escrow accounts are administered by an intermediary. Cash restricted pursuant to like-kind exchange agreements remains restricted for a maximum of 180 days from the date of the property sale pending the acquisition of replacement property. Restricted cash may also include cash reserved by other contractual agreements (such as asset purchase agreements) for a specified purpose and therefore is not available for use for other purposes. Restricted cash is included with cash and cash equivalents in the accompanying Condensed Consolidated Statements of Cash Flows.

DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS In 2005, we sold substantially all the assets of our Chemicals business to a subsidiary of Occidental Chemical Corporation. The financial results of the Chemicals business are classified as discontinued operations in the accompanying Condensed Consolidated Statements of Comprehensive Income for all periods presented. Results from discontinued operations are as follows: in millions Three Months Ended Six Months Ended 2024 2023 2024 2023 Pretax loss $ (2.7) $ (4.9) $ (5.0) $ (7.9) Income tax benefit 0.7 1.2 1.3 2.1 Loss on discontinued operations, net of tax $ (2.0) $ (3.7) $ (3.7) $ (5.8) Our discontinued operations include charges related to general and product liability costs, including legal defense costs, and environmental remediation costs associated with our former Chemicals business (including certain matters as discussed in Note 8). There were no revenues from discontinued operations for the periods presented.
EARNINGS PER SHARE (EPS)	EARNINGS PER SHARE (EPS) All dilutive common stock equivalents are reflected in our earnings per share calculations. In periods of loss, shares that otherwise would have been included in our diluted weighted-average common shares outstanding computation would be excluded.
RECLASSIFICATIONS	RECLASSIFICATIONS As a result of a first quarter 2024 change in our internal management reporting structure, prior period segment information has been revised to conform to our current segment reporting structure. This change had no impact on our prior consolidated results of operations, financial position or cash flows (refer to Note 13 for further information).
