Vulcan Materials CO

NOTE 6: 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 prior periods, 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:

For the twelve-month period ending March 31, 2026, we estimate that $2.4 million of the $17.3 million net of tax loss in AOCI will be reclassified to interest expense.

NOTE 7: DEBT

Debt is detailed as follows:

1 Borrowings on the bank line of credit and commercial paper are classified as short-term if we intend to repay within twelve months and as long-term if we have the intent and ability to extend payment beyond twelve months.

Discounts and debt issuance costs are amortized using the effective interest method over the terms of the respective notes resulting in $1.4 million and $3.5 million of net interest expense for these items for the three months ended March 31, 2025 and 2024, respectively.

LINE OF CREDIT AND COMMERCIAL PAPER PROGRAM

Our $1,600.0 million commercial paper program was established in August 2022 and matures in November 2029. Commercial paper borrowings bear interest at rates determined at the time of borrowing and as agreed between us and the commercial paper investors. As of March 31, 2025, we had $550.0 million in long-term commercial paper borrowings with a 4.69% effective interest rate.

Our $1,600.0 million unsecured line of credit was amended in November 2024 to extend the maturity date from August 2027 to November 2029. Our line of credit contains covenants customary for an unsecured investment-grade facility. As of March 31, 2025, we were in compliance with the line of credit 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 March 31, 2025, 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 March 31, 2025, our available borrowing capacity under the line of credit was $1,576.1 million. Utilization of the borrowing capacity was as follows:

▪None was borrowed

▪$23.9 million was used to support standby letters of credit

TERM DEBT

All of our $4,990.7 million (face value) of term debt (which includes $550.0 million of commercial paper) is unsecured. All of the covenants in the debt agreements are customary for investment-grade facilities. As of March 31, 2025, we were in compliance with all term debt covenants.

In November 2024, we issued $500.0 million of 4.95% senior notes due 2029, $750.0 million of 5.35% senior notes due 2034 and $750.0 million of 5.70% senior notes due 2054. Total proceeds of $1,975.0 million (net of discounts and transaction costs), together with cash on hand, were used to provide liquidity for acquisitions in 2024 and debt maturing in 2025.

In March 2025, we redeemed the $400.0 million senior notes due April 2025 using cash on hand.

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 ofone year, renew automatically and can only be modified or canceled with the approval of the beneficiary. Except for $9.6 million of letters of credit related to acquisitions completed in 2024, 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 March 31, 2025 are summarized by purpose in the table below:

NOTE 8: 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 $624.9 million as of March 31, 2025.

As summarized by purpose in Note 7, our standby letters of credit totaled $33.5 million as of March 31, 2025.

As described in Note 9, our asset retirement obligations totaled $429.5 million as of March 31, 2025.

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:

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 court granted the motion to enter the Consent Decree in December 2024. Occidental thereafter filed an appeal challenging the entry of the Consent Decree. The appeal remains pending. 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. 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 and Occidental have settled their claims against each other; 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 inthree 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 inone of thethree 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. In 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 appealed those judgments. In December 2024, the Court of Appeal affirmed the dismissal of most of those damage claims but remanded the dispute to the District Court for further adjudication of an indemnity claim under one of the agreements. Vulcan and Texas Brine have each sought discretionary review of the Court of Appeal's December 2024 rulings. We cannot at this time reasonably estimate the range of liability, if any, that could result from Texas Brine's indemnity claim or should the Louisiana Supreme Court exercise jurisdiction to review any of the December 2024 appellate court rulings. At this time, we also cannot reasonably estimate a range of liability pertaining to the claims brought by the State of Louisiana.

▪1,1,1-TRICHLOROETHANE LITIGATION (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. Vulcan faces liabilities related to 1,1,1-trichloroethane stabilized with 1,4-dioxane ("TCA"). We are one of the defendants in cases filed in both state and federal courts, includingone case filed by the State of New Jersey. According to the various complaints, the plaintiffs seek damages including, but not limited to, unspecified compensatory damages associated with the remediation of water wells allegedly contaminated with 1,4-dioxane, natural resource damages, disgorgement of profits from the sale of TCA, punitive damages, as well as penalties and attorney's fees under various 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 under a Cleanup and Abatement Order (CAO) to include 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 treatment system is fully operational. In October 2024, the RWQCB made a request under the CAO for a work plan to install additional monitoring wells and optimize and expand the existing on-site remediation system. This request complements expansion discussions with the EPA and other stakeholders, as part of the Alternative Design Work Plan (ADWP) which was submitted in January 2025. Currently-anticipated costs of these on-site source control activities, including those associated with this work plan, 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 oftwo 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 draft Supplemental Report in March 2023 and a draft ADWP in May 2023. Similar to the PDI Evaluation Report, the draft Supplemental Report and draft 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 thetwo wells proposed by the EPA. In conjunction with its review of the draft Supplemental Report, the EPA held an initial meeting with stakeholders, including LADWP, in November 2023. Since that time, Vulcan has participated in several additional meetings and responded to several rounds of comments. After receiving final comments from the LADWP, EPA and the RWQCB, Vulcan submitted a final Supplemental Report to the EPA in April 2025.

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 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 Vulcan and the third party, which claims indemnity from Vulcan. 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 and recent settlement discussions, 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 constructingtwo 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 NHW system commenced operation in late 2024, and the NHC system is expected to commence operation in 2025. Both systems will 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" under the caption "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 2025.

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.

NOTE 9: 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 ARO liability is accreted through charges to operating expenses. If the ARO liability 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:

ARO operating costs are reported in cost of revenues. ARO liabilities are reported within other noncurrent liabilities in our accompanying Condensed Consolidated Balance Sheets.

Reconciliations of the carrying amounts of our ARO liabilities are as follows:

The increase in ARO liabilities from the prior year primarily relates to acquisitions completed in 2024 (see Note 16) and cost adjustments for a number of aggregates properties in California that are being reclaimed for alternative uses post mining.

NOTE 10: BENEFIT PLANS

PENSION PLANS

We sponsortwo 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:

The contributions to pension plans for the three months ended March 31, 2025 and 2024, 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:

DEFINED CONTRIBUTION PLANS

In addition to our pension and postretirement plans, we sponsor seven 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 $17.0 million and $30.4 million for the three months ended March 31, 2025 and 2024, respectively.

NOTE 11: OTHER COMPREHENSIVE INCOME

Comprehensive income comprises two subsets: net earnings and other comprehensive income (OCI). The components of OCI are presented in the accompanying Condensed Consolidated Statements of Comprehensive Income, net of applicable taxes.

Amounts in accumulated other comprehensive income (loss) (AOCI), net of tax, are as follows:

Changes in AOCI, net of tax, for the three months ended March 31, 2025 are as follows:

Amounts reclassified from AOCI to earnings are as follows:

NOTE 12: EQUITY

Our capital stock consists solely of common stock, par value $1.00 per share, of which 480,000,000 shares may be issued. Holders of our common stock are entitled toone vote per share. We may also issue 5,000,000 shares of preferred stock, butno shares have been issued. The terms and provisions of such shares will be determined by our Board of Directors upon any issuance of preferred shares in accordance with our Certificate of Incorporation.

There wereno shares held in treasury as of March 31, 2025, December 31, 2024 and March 31, 2024.

Our common stock purchases (all of which were open market purchases) and subsequent retirements for the year-to-date periods ended are as follows:

1 The amount paid to purchase shares in excess of the par value and related excise taxes are recorded in retained earnings.

As of March 31, 2025,6,647,118 shares may be purchased under the current authorization of our Board of Directors.

Changes in total equity are summarized below:

NOTE 13: SEGMENT REPORTING

Our operating segments are based on our internal management reporting structure. Our chief operating decision maker, the Chairman and Chief Executive Officer, evaluates our operating results through reportable segment gross profit. This financial metric is used to review operating trends, perform analytical comparisons between periods and monitor budget-to-actual variances on a monthly basis in order to assess performance and allocate resources.

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.

SEGMENT FINANCIAL DISCLOSURE

1 Includes product sales (crushed stone, sand and gravel, sand and other aggregates), freight & delivery costs that we pass along to our customers, and service revenues (see Note 4) related to our aggregates business.

2 Includes product sales as well as service revenues (see Note 4) from our asphalt construction paving business.

SEGMENT FINANCIAL DISCLOSURE (CONTINUED)

1 Depreciation, Depletion, Accretion & Amortization (DDA&A) for each segment is included in cost of revenues.

2 Capital expenditures include changes in accruals for purchases of property, plant & equipment. Capital expenditures exclude property, plant & equipment obtained by business acquisitions.

3 Certain temporarily idled assets are included within a segment's Identifiable Assets, but the associated DDA&A is shown within Other in the DDA&A section above as the related DDA&A is excluded from segment gross profit.

4 The increase in total identifiable assets is primarily due to acquisitions completed in 2024 (see Note 16 for additional information).

NOTE 14: SUPPLEMENTAL CASH FLOW INFORMATION

Supplemental information referable to our Condensed Consolidated Statements of Cash Flows is summarized below:

1 Excludes changes in accruals.

NOTE 15: 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 wereno charges for goodwill impairment in the three-month periods ended March 31, 2025 and 2024. Accumulated goodwill impairment losses amount to $390.2 million ($252.7 million in our former Cement segment and $137.5 million in our Concrete segment).

Changes in the carrying amount of goodwill by reportable segment from December 31, 2024 to March 31, 2025 are shown below:

NOTE 16: ACQUISITIONS AND DIVESTITURES

BUSINESS ACQUISITIONS

2025 BUSINESS ACQUISITIONS — Through the three months ended March 31, 2025, we completedno business acquisitions.

2024 BUSINESS ACQUISITIONS — Through the three months ended March 31, 2024, we acquired operations in North Carolina for cash consideration of $12.3 million. For the full year 2024, including adjustments made in the current year, we acquired the following operations for total consideration of $2,299.0 million ($2,261.4 million cash and $37.6 million noncash):

▪Alabama — aggregates, asphalt mix and construction paving operations

▪California — aggregates, asphalt and ready-mixed concrete operations

▪North Carolina — aggregates operations

▪South Carolina — aggregates operations

▪Texas — asphalt mix and construction paving operations

While none of these acquisitions were individually material, our fourth quarter acquisitions of Wake Stone Corporation (Wake Stone) and Superior Ready Mix, L.P. (Superior) were collectively material. The unaudited pro forma financial information in the table below summarizes the results of operations for Vulcan, Wake Stone and Superior as if they were combined as of January 1, 2023. The pro forma financial information does not reflect any cost savings, operating efficiencies or synergies as a result of these acquisitions. Consistent with the assumed acquisition date of January 1, 2023, the pro forma information excludes transactions between Vulcan, Wake Stone and Superior. The following pro forma information also includes: 1) charges directly attributable to the acquisitions, including acquisition related expenses; 2) cost of sales related to the sale of acquired inventory marked up to fair value; 3) depreciation, depletion, amortization & accretion expense related to the mark up to fair value of acquired assets; 4) interest expense reflecting the new debt structure; and 5) tax effects of the business combination:

The unaudited pro forma results above may not be indicative of the results that would have been obtained had these acquisitions occurred at the beginning of 2023, nor does it intend to be a projection of future results.

The fair value of consideration transferred for the Wake Stone and Superior acquisitions and the preliminary amounts (pending final appraisals of intangible assets and property, plant & equipment as well as working capital adjustments) of assets acquired and liabilities assumed are summarized below:

As a collective result of the Wake Stone and Superior acquisitions, as well as other immaterial acquisitions completed in 2024, we recognized $279.7 million of amortizable intangible assets and $370.4 million of goodwill. The amortizable intangible assets will be amortized against earnings over a weighted-average of approximately 20 years and will be deductible for income tax purposes over 15 years. The $370.4 million of goodwill primarily represents deferred tax liabilities generated from carrying over the seller's tax basis in the assets acquired as well as synergies expected to be realized from acquiring established businesses 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. Of the total goodwill recognized, $60.0 million will be deductible for income tax purposes.

DIVESTITURES AND PENDING DIVESTITURES

In 2025, we sold:

▪First quarter — non-strategic aggregates locations in rural West Texas with limited reserves resulting in an immaterial gain

We hadno significant divestitures through the three months ended March 31, 2024.

No material assets met the criteria for held for sale at March 31, 2025, December 31, 2024 or March 31, 2024.
