The Company’s Building Materials business includes two reportable segments: East Group and West Group.

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and in Article 10 of Regulation S-X. The Company has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. In the opinion of management, the interim consolidated financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods. The consolidated results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results expected for other interim periods or the full year.

financial statements. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

The preparation of the Company’s consolidated financial statements requires management to make certain estimates and assumptions about future events. As future events and their effects cannot be fully determined with precision, actual results could differ significantly from estimates. Changes in estimates are reflected in the consolidated financial statements in the period in which the change in estimate occurs.

The Company is restricted from utilizing the cash for purposes other than the purchase of qualified assets for a designated period from receipt of the proceeds from the sale of the exchanged assets. There was no restricted cash at December 31, 2024.

The statements of cash flows reflect cash flow changes and balances for cash, cash equivalents and restricted cash on an aggregated basis.

Earnings per Common Share

The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta. The denominator for basic earnings per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is computed assuming that the weighted-average number of common shares is increased by the conversion, using the treasury stock method, of awards to be issued to employees and nonemployee members of the Company’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive.

The following table reconciles the denominator for basic and diluted earnings per common share:

New Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU 2023-09 requires public entities to disclose, on an annual basis, a tabular tax rate reconciliation using both percentages and currency amounts, disaggregated into specified categories. Certain reconciling items are further disaggregated by nature and jurisdiction to the extent those items exceed a specified threshold. Additionally, all entities are required to disclose income taxes paid, net of refunds received, disaggregated by federal, state/local, and foreign taxes and by individual jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. The ASU also requires additional qualitative disclosures. ASU 2023-09 is effective prospectively for annual periods beginning after December 15, 2024, and early adoption and retrospective application are permitted. The ASU will impact the Company's income tax disclosures beginning with the financial statements included in the 2025 Annual Report on Form 10-K, but will have no impact on its results of operations, cash flows or financial condition.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (DISE), which requires public entities to disaggregate any relevant expense caption presented on the face of the income statement within continuing operations into the following required natural expense categories, as applicable: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion and amortization recognized as part of oil- and gas-producing activities or other depletion expenses. These disclosures must be made in a tabular format in the footnotes to the financial statements. The new standard does not change the requirements for the presentation of expenses on the face of the statement of earnings. The ASU is effective prospectively for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, and early adoption and retrospective application are permitted. The ASU will impact the Company's expense disclosures beginning with the financial statements included in the 2027 Annual Report on Form 10-K, but will have no impact on its results of operations, cash flows or financial condition.

Reclassifications

Certain reclassifications have been made in the Company's financial statements of the prior year to conform to the current-year presentation. The reclassifications had no impact on the Company’s previously reported results of operations, financial condition or cash flows.

2.Business Combinations and Divestitures

Business Combinations

Revenues and pretax earnings attributable to operations acquired in the first six months of 2024 (as subsequently described) included in the Company's consolidated statements of earnings and comprehensive earnings were $83 million and $11 million, respectively, for the three months ended June 30, 2024, and $97 million and $12 million, respectively, for the six months ended June 30, 2024. The pretax earnings for both the quarter and year-to-date periods ended June 30, 2024 include a $20 million charge for the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting for the Blue Water Industries LLC transaction.

R.E. Janes Gravel Co. On December 13, 2024, the Company acquired R.E. Janes Gravel Co. (RE Janes), an aggregates bolt-on in Texas. The Company has recorded preliminary fair values of the assets acquired and liabilities assumed, which are subject to additional reviews that are not yet complete. Thus, these amounts are subject to change during the measurement period, which extends no longer than one year from the consummation date, and remains open as of June 30, 2025. Specific accounts subject to ongoing purchase accounting adjustments, include, but are not limited to, property, plant and equipment; goodwill; and other liabilities. The goodwill generated by the transaction is deductible for income tax purposes. The acquisition is reported in the Company's West Group and is immaterial for other business combination disclosures, including pro-forma results of operations.

Divestitures

On February 9, 2024, the Company completed the sale of its South Texas cement business and certain of its related ready mixed concrete operations to CRH Americas Materials, Inc., a subsidiary of CRH plc, for $2.1 billion in cash plus normal customary closing adjustments. Specifically, the divested facilities included the Hunter cement plant in New Braunfels, Texas, related cement distribution terminals and 20 ready mixed concrete plants that served the Austin and San Antonio region. The divestiture provided proceeds the Company used to consummate the BWI Southeast acquisition. The transaction resulted in a pretax gain of $1.3 billion, which is included in Other operating (income) expense, net, on the Company's consolidated statement of earnings and comprehensive earnings for the six months ended June 30, 2024 and is exclusive of transaction expenses incurred due to the divestiture. The divested operations and the gain on divestiture were reported in the West Group.

Subsequent Events

On July 25, 2025, the Company acquired Premier Magnesia, LLC (Premier), a privately-owned producer and distributor of magnesia-based products, using cash on hand and credit facility borrowings. Premier is the largest producer of natural magnesite and magnesium sulfate, or Epsom salt, in the United States, with facilities in Nevada, North Carolina, Indiana and Pennsylvania. This transaction expands the Company's product offerings to new and existing customers and enhances the Company's Magnesia Specialties business. The Company is in the process of determining the acquisition-date fair values of assets acquired and liabilities assumed.

On August 3, 2025, the Company entered into a definitive agreement with Quikrete Holdings, Inc. (Quikrete) for the exchange of certain assets. Under the terms of the agreement, Martin Marietta will receive aggregates operations producing approximately 20 million tons annually in Virginia, Missouri, Kansas and Vancouver, British Columbia, as well as $450 million of cash. In exchange, Quikrete will receive the Company’s Midlothian cement plant, related cement terminals and North Texas ready mixed concrete assets. The transaction is expected to close in the first quarter of 2026, subject to regulatory approvals and other customary closing conditions.

The Company has a credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent, Deutsche Bank Securities, Inc., PNC Bank, Truist Bank and Wells Fargo Bank, N.A., as Syndication Agents, and the lenders party thereto (the Credit Agreement), which provides for an $800 million five-year senior unsecured revolving facility (the Revolving Facility) with a maturity date of December 21, 2029. Borrowings under the Revolving Facility bear interest, at the Company’s option, at rates based upon the Secured Overnight Financing Rate (SOFR) or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. Any outstanding principal amounts, together with interest accrued thereon, are due in full on that maturity date. There were no borrowings outstanding under the Revolving Facility as of June 30, 2025 and December 31, 2024. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. At June 30, 2025 and December 31, 2024, the Company had $3 million of outstanding letters of credit issued under the Revolving Facility.

The Credit Agreement requires the Company’s ratio of consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio any debt incurred in connection with certain acquisitions during the quarter or three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 4.00x. Additionally, if no amounts are outstanding under the Revolving Facility or the Company's trade receivable securitization facility (discussed below), consolidated debt, as defined, which includes debt for which the Company is a guarantor, shall be reduced in an amount equal to the lesser of $500 million or the sum of the Company’s unrestricted cash and temporary investments, for purposes of the covenant calculation. The Company was in compliance with the Ratio at June 30, 2025.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility) that matures on September 17, 2025. The Trade Receivable Facility, with Truist Bank, Regions Bank, First-Citizens Bank & Trust Company, and certain other lenders that may become a party to the facility from time to time, is backed by eligible trade receivables, as defined. Borrowings are limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold or contributed to the wholly-owned, special-purpose subsidiary. The Company continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned, special-purpose subsidiary. Borrowings under the Trade Receivable Facility bear interest at a rate equal to the Adjusted Term Secured Overnight Financing Rate (Adjusted Term SOFR), as defined, plus 0.8%. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. Subject to certain conditions, including lenders providing the requisite commitments, the Trade Receivable Facility may be increased to a borrowing base not to exceed $500 million. There were no borrowings outstanding under the Trade Receivable Facility as of June 30, 2025 and December 31, 2024.

6.Financial Instruments

The Company’s financial instruments include temporary cash investments, restricted cash, accounts receivable, accounts payable, publicly-registered long-term notes and debentures.

Temporary cash investments are placed primarily in money market funds, money market demand deposit accounts and Eurodollar time deposit accounts with financial institutions. The Company’s cash equivalents have maturities of less than three months. Due to the short maturity of these investments, they are carried on the consolidated balance sheets at cost, which approximates fair value.

Restricted cash at June 30, 2025 is held in a trust account with a third-party intermediary. Due to the short-term nature of this account, the carrying value of restricted cash approximates its fair value.

(Continued)

Accounts receivable are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. However, accounts receivable are more heavily concentrated in certain states, namely Texas, North Carolina, Colorado, California, Georgia, Florida, Minnesota, Arizona, South Carolina, and Iowa. The carrying values of accounts receivable approximate their fair values.

Accounts payable represent amounts owed to suppliers and vendors. The estimated carrying value of accounts payable approximates its fair value due to the short-term nature of the payables.

The carrying value and fair value of the Company’s debt were $5.4 billion and $4.9 billion, respectively, at June 30, 2025 and $5.4 billion and $4.8 billion, respectively, at December 31, 2024. The estimated fair value of the Company’s publicly-registered long-term debt was estimated based on Level 1 of the fair value hierarchy using quoted market prices.

7.Income Taxes

The Company's effective income tax rate reflects the effect of federal and state income taxes on earnings and the impact of differences in book and tax accounting arising primarily from the permanent tax benefits associated with the statutory depletion deduction for mineral reserves. The effective income tax rates were 20.5% and 25.0% for the six months ended June 30, 2025 and 2024, respectively. The higher 2024 effective income tax rate versus 2025 was driven by the impact of the February 2024 divestiture of the South Texas cement business and certain related ready mixed concrete operations, which reflected the write off of certain nondeductible goodwill and was treated as a discrete tax event.

The Company invests in renewable energy investment entities which qualify for tax credits and other tax benefits (RETC projects) and are accounted for under the proportional amortization method. For the six months ended June 30, 2025, the Company's annualized effective tax rate includes the proportional amortization of these investments of $46 million, offset by $42 million of tax credits and $8 million of other tax benefits. The proportional amortization and related tax credits and benefits for the six months ended June 30, 2024 were immaterial.

As of June 30, 2025, the Company has committed to equity contributions of $45 million for tax equity investments related to RETC projects. These commitments, which are expected to be paid in 2025, are recorded in Other current liabilities on the consolidated balance sheet. On July 1, 2025, the Company entered into an agreement to invest an additional $45 million for RETC projects by the end of 2025.

The Internal Revenue Service has provided certain disaster tax relief for North Carolina businesses affected by Hurricanes Debby and Helene, which allows the Company to defer estimated federal and certain state income, payroll and excise tax payments for the period from August 2024 through September 2025. The deferred obligation will be due September 25, 2025. The Company had deferred income tax payments of $150 million under this provision as of June 30, 2025.

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (OBBBA) that, among other provisions, makes 100% bonus depreciation permanent, restores the ability to expense domestic research expenditures, and modifies the taxation of foreign earnings. The OBBBA is not expected to have a material impact on the Company’s annual estimated income tax rate, but will result in a reclassification between current taxes payable and deferred tax liabilities which will be reflected in the period ending September 30, 2025.

8.Pension Benefits

The net periodic benefit cost for pension benefits includes the following components:

Three Months Ended June 30, Six Months Ended June 30,

Amortization of:
Prior service cost 1 2 3 3
Actuarial loss 1
Net periodic benefit cost $ 4 $ 6 $ 10 $ 11

The components of net periodic benefit cost, other than service cost, are included in the line item Other nonoperating income, net, in the consolidated statements of earnings and comprehensive earnings. Based on the roles of the employees, service cost is included in the Cost of revenues or Selling, general and administrative expenses line items in the consolidated statements of earnings and comprehensive earnings.

9.Commitments and Contingencies

Legal and Administrative Proceedings

The Company is engaged in certain legal and administrative proceedings incidental to its normal business activities, including proceedings relating to environmental matters. The Company considers various factors in assessing the probable outcome of each matter, including but not limited to the nature of existing legal proceedings and claims, the asserted or possible damages, the jurisdiction and venue of the case and whether it is a jury trial, the progress of the case, existing law and precedent, the opinions or views of legal counsel and other advisers, the Company’s experience in similar cases and the experience of other companies, the facts available to the Company at the time of assessment, and how the Company intends to respond to the proceeding or claim. The Company’s assessment of these factors may change over time as proceedings or claims progress. The Company believes the probability is remote that the outcome of any currently pending legal or administrative proceeding will result in a material loss to the Company's financial condition, results of operations or cash flows, as a whole, based on currently available facts.

Letters of Credit

In the normal course of business, the Company provides certain third parties with standby letter of credit agreements guaranteeing its payment for certain insurance claims, contract performance and permit requirements. At June 30, 2025, the Company was contingently liable for $32 million in letters of credit.

10.Segments

The Building Materials business is comprised of four divisions that represent individual operating segments. These operating segments are consolidated into two reportable segments, the East Group and the West Group, for financial reporting purposes, as they meet the aggregation criteria. The Magnesia Specialties business represents an individual operating and reportable segment.

The Company’s Chief Operating Decision Maker (CODM) is the Chair, President and Chief Executive Officer. The CODM reviews results by reportable segment on a quarterly basis and allocates resources to achieve the Company’s strategic objectives based on an evaluation of each reportable segment’s performance. This evaluation is largely based on segment earnings from operations, as management believes this is the best metric of segment profitability and operating performance. Segment earnings from operations is also a measure in the determination of incentive compensation targets and awards. Segment earnings from operations includes revenues less cost of revenues; selling, general and administrative expenses; other operating income and expenses, net; and exclude interest income and expense; other nonoperating income and expenses, net; and income tax expense.

The significant expense categories shown below align with the segment-level information regularly provided to the CODM. Other costs of revenues for each reportable segment mainly include repairs and maintenance, contract services, supplies and royalties.

Corporate loss from operations primarily includes depreciation and amortization; expenses for corporate administrative functions; acquisition, divestiture and integration expenses; and other nonrecurring income and expenses not attributable to operations of the Company's operating segments.

The following tables display selected financial data for the Company’s reportable segments. Revenues, as presented on the consolidated statements of earnings and comprehensive earnings, reflect the elimination of intersegment revenues, which represent sales from one segment to another segment and are immaterial. Income tax expense is not allocated to the Company's reportable segments.

Earnings from operations for the West Group for the six months ended June 30, 2024 included a $1.3 billion gain and $16 million in transaction expenses on the divestiture of the South Texas cement business and certain of its related ready mixed concrete operations (see Note 2) and a noncash asset and portfolio rationalization charge of $50 million (see Note 13).

Performance Obligations. Performance obligations are contractual promises to transfer or provide a distinct good or service for a stated price. The Company’s product sales agreements are single-performance obligations that are satisfied at a point in time. Performance obligations within paving service agreements are satisfied over time, primarily ranging from one day to two years. Customer payments for the paving operations are based on a contractual billing schedule and are typically "paid-when-paid", meaning the Company is paid once the customer is paid.

Future revenues from unsatisfied performance obligations at June 30, 2025 and 2024 were $252 million and $377 million, respectively, where the remaining periods to complete these obligations ranged from one month to 30 months and one month to 18 months, respectively.

Service Revenues. Service revenues were $102 million and $117 million for the three months ended June 30, 2025 and 2024, respectively, and reported in the West Group. Service revenues for the six months ended June 30, 2025 and 2024 were $137 million and $143 million, respectively. Service revenues include paving services located in California through its April 2025 divestiture date and Colorado.

13.Other Operating (Expense) Income, Net

Other operating income, net, is comprised generally of gains and losses on divestitures and the sale of assets; asset and portfolio rationalization charges; recoveries and losses related to certain customer accounts receivable; recoveries and losses on the resolution of contingency accruals; rental, royalty and services income; and accretion expense and depreciation expense related to asset retirement obligations. For the six months ended June 30, 2024, other operating income, net, included a $1.3 billion pretax gain on the divestiture of the South Texas cement business and certain of its related ready mixed concrete operations, which was partially offset by a $50 million pretax, noncash asset and portfolio rationalization charge.

The noncash asset and portfolio rationalization charge for the six months ended June 30, 2024 relates to the Company's decision to discontinue usage of certain long-haul distribution facilities to transport aggregates products into Colorado as the Albert Frei & Sons, Inc. acquisition completed in January 2024 provides more economical, local aggregates supply. This charge, which is reported in the West Group, reflects the Company's evaluation of the recoverability of certain long-lived assets, including property, plant and equipment and operating lease right-of-use assets, for the cessation of these railroad operations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

OVERVIEW

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. As of June 30, 2025, the Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 390 quarries, mines and distribution yards in 28 states, Canada and The Bahamas. Martin Marietta also provides cement and downstream products, namely, ready mixed concrete, asphalt and paving services, in certain vertically-integrated structured markets where the Company has a leading aggregates position. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement and ready mixed concrete and asphalt and paving product lines are reported collectively as the Building Materials business.

The Company’s Building Materials business includes two reportable segments: East Group and West Group.

Facility Types Quarries, Mines, Asphalt Plants and<br><br>Distribution Facilities Quarries, Cement Plant, Asphalt Plants, Ready Mixed Concrete Plants and<br><br>Distribution Facilities
Modes of Transportation Truck, Railcar, Ship and Barge Truck and Railcar

The Building Materials business is significantly affected by weather patterns, seasonal changes and other climate-related conditions. Production and shipment levels for aggregates, cement, ready mixed concrete and asphalt materials correlate with general construction activity levels, most of which occur in the spring, summer and fall. Thus, production and shipment levels vary by quarter. Excessive rainfall, drought, wildfire and extreme hot and cold temperatures can also jeopardize production, shipments and profitability in all markets served by the Company. Due to the potentially significant impact of weather on the Company’s operations, current-period results are not necessarily indicative of expected performance for other interim periods or the full year.

The Company has a Magnesia Specialties business with manufacturing facilities in Manistee, Michigan, and Woodville, Ohio. The Magnesia Specialties business produces magnesia-based products used in a wide range of industrial, agricultural and environmental applications, as well as dolomitic lime, which is primarily used as a fluxing agent in domestic steel production and as a key raw material in the Company's magnesia-based products. Dolomitic lime is also used in various other end use applications including soil stabilization.

CRITICAL ACCOUNTING POLICIES

The Company outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2024. There were no changes to the Company’s critical accounting policies during the six months ended June 30, 2025.

RESULTS OF OPERATIONS

Earnings before interest; income taxes; depreciation, depletion and amortization; earnings/loss from nonconsolidated equity affiliates; acquisition, divestiture and integration expenses; the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting (the Inventory Markup); nonrecurring gain on divestiture; and noncash asset and portfolio rationalization charge, or Adjusted EBITDA, is an indicator used by the Company and investors to evaluate the Company’s operating performance from period to period. The Company has elected to add back, for purposes of its Adjusted EBITDA calculation, acquisition, divestiture and integration expenses and the Inventory Markup only for transactions with consideration of $2.0 billion or more and expected acquisition, divestiture and integration expenses of at least $15 million.

Adjusted EBITDA is not defined by accounting principles generally accepted in the United States (GAAP) and, as such, should not be construed as an alternative to net earnings attributable to Martin Marietta, earnings from operations or operating cash flow. Since Adjusted EBITDA excludes some, but not all, items that affect net earnings and may vary among companies, Adjusted EBITDA as presented by the Company may not be comparable with similarly titled measures of other companies.

The following table presents a reconciliation of net earnings attributable to Martin Marietta to Adjusted EBITDA:

Building Materials Business

The following table presents shipment data for the Building Materials business:

Three Months Ended June 30,
2025 2024 % Change
(In Millions)
Aggregates tons 52.7 53.0 (0.6 )%
Cement tons 0.5 0.5 (11.5 )%
Ready Mixed Concrete cubic yards 1.2 1.2 (1.2 )%
Asphalt tons 2.3 2.5 (6.6 )%

Second-quarter aggregates shipments decreased 0.6% to 52.7 million tons as wet weather in May 2025 and continued residential market softness across Southeast, Southwest and Midwest markets more than offset contributions from acquisitions. Pricing momentum continued as average selling price (ASP) increased 7.4% to $23.21 per ton.

Aggregates gross profit increased 9% from the prior-year quarter to $430 million and gross margin expanded 94 basis points to 33%, driven by organic pricing growth in excess of cost increases. Aggregates gross profit per ton increased 10% to $8.16. 2024 aggregates gross profit included a $20 million Inventory Markup charge associated with the Blue Water Industries LLC acquisition (the BWI Southeast acquisition; see Note 2 to the unaudited consolidated financial statements).

Cement and ready mixed concrete revenues decreased 6% to $245 million compared with the prior-year quarter due primarily to slower residential demand. Gross profit decreased 25% to $54 million due to higher ready mix raw material costs.

Asphalt and paving revenues decreased 7% from the prior-year quarter to $228 million, driven by lower asphalt shipments in Colorado and Minnesota and the sale of the California paving business in April 2025. Gross profit decreased 8% to $33 million due to reduced operating leverage stemming from lower shipments.

Aggregates End-Use Markets

Aggregates shipments to the infrastructure market increased 1% quarter-over-quarter as volumes to several highway and Hurricane Helene relief projects were offset by inclement weather in several of the Company's key markets. The infrastructure market accounted for 37% of second-quarter aggregates shipments.

Aggregates shipments to the nonresidential market were flat, reflecting contributions from distribution and data centers in the Southeast and Southwest, offset by delayed project starts in Texas. The nonresidential market represented 35% of second-quarter aggregates shipments.

Aggregates shipments to the residential market decreased 4%, driven by continued general softness in single-family housing resulting from affordability headwinds. The residential market accounted for 23% of second-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of second-quarter aggregates shipments. Volumes to this end use market were flat quarter-over-quarter.

Magnesia Specialties Business

Magnesia Specialties second-quarter revenues of $90 million increased 12% while gross profit increased 32% to $36 million, and gross margin improved 605 basis points to 40% due to higher prices, improved lime shipments and operational reliability and efficiency gains.

Consolidated Operating Results

Consolidated SG&A for the second quarter of 2025 was 6.0% of revenues compared with 6.7% in the prior-year quarter resulting from lower stock compensation expense.

Net earnings attributable to Martin Marietta were $328 million, or $5.43 per diluted share, in 2025 compared with $294 million, or $4.76 per diluted share, in 2024. 2024 included an after-tax charge of $15 million, or $0.24 per diluted share, for the Inventory Markup and an after-tax charge of $16 million, or $0.26 per diluted share, for acquisition and integration expenses related to the BWI Southeast acquisition.

The following table presents shipment data for the Building Materials business:

Six Months Ended June 30,
2025 2024 % Change
(In Millions)
Aggregates tons 91.7 89.6 2.3 %
Cement tons 0.9 1.1 (19.5 )%
Ready Mixed Concrete cubic yards 2.3 2.4 (4.0 )%
Asphalt tons 3.0 3.0 (0.9 )%

Year-to-date aggregates shipments increased 2.3%, due to contributions from acquisitions, partially offset by adverse weather across many Southeast, Southwest and Midwest markets. Aggregates average selling price per ton of $23.45 increased 7.2% due to strong realization of the cumulative effects of 2024 and 2025 price increases. Aggregates gross profit improved 15% to $726 million, driven by organic pricing growth in excess of cost increases and margin-accretive acquisitions.

Cement and ready mixed concrete revenues decreased 9% to $477 million, primarily attributable to slower residential demand, weather-driven delays and the February 2024 divestiture of the South Texas cement business and certain of its related ready mixed concrete operations (the Divestiture; see Note 2 to the unaudited consolidated financial statements). Gross profit decreased 25% to $78 million, compared with the prior-year period, reflecting lower revenues and higher raw material costs.

Asphalt and paving revenues increased 2% to $308 million. Gross profit decreased 27% to $11 million, compared with the prior-year period, as the combination of lower asphalt shipments and higher raw materials costs more than offset pricing growth.

Aggregates End-Use Markets

Aggregates shipments to the infrastructure market increased 2% as contributions from operations acquired more than offset weather-driven project delays. The infrastructure market accounted for 35% of year-to-date aggregates shipments.

(Continued)

Aggregates shipments to the nonresidential market increased 2%, reflecting contributions from acquired operations and increased data center shipments that more than offset wet weather in many of the Company's markets. The nonresidential market represented 36% of year-to-date aggregates shipments.

Aggregates shipments to the residential market increased 1%, driven by contributions from acquired operations. The Company continues to experience demand softness in single-family housing within most markets, however, demographic trends and undersupply, particularly in key Sunbelt markets, remain intact. The residential market accounted for 24% of year-to-date aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of year-to-date aggregates shipments. Volumes to this end use market increased 9% year-to-date due to robust agricultural lime and ballast shipments.

Magnesia Specialties Business

Magnesia Specialties year-to-date revenues of $178 million increased 10% and gross profit increased 32% to $74 million, due to improved lime shipments, strong pricing improvement and continued cost discipline.

Consolidated Operating Results

Consolidated SG&A for the six months ended June 30 was 7.6% of revenues compared with 7.8% in the prior-year period.

For the six months ended June 30, consolidated other operating income, net, was $16 million in 2025 and $1.3 billion in 2024. The 2024 amount included a $1.3 billion pretax gain on the Divestiture, which was partially offset by a $50 million pretax, noncash asset and portfolio rationalization charge (the Rationalization Charge; see Note 13 to the unaudited consolidated financial statements).

For the six months ended June 30, other nonoperating income, net, was $20 million and $46 million in 2025 and 2024, respectively, with the decrease resulting from lower interest income.

For the six months ended June 30, 2025 and 2024, the effective income tax rates were 20.5% and 25.0%, respectively. The higher 2024 effective income tax rate versus 2025 was driven by the Divestiture, which reflected the write-off of certain nondeductible goodwill and was treated as a discrete tax event.

For the six months ended June 30, net earnings attributable to Martin Marietta were $444 million, or $7.31 per diluted share, in 2025 compared with $1.3 billion, or $21.66 per diluted share, in 2024. 2024 included an after-tax gain of $976 million, or $15.79 per diluted share, on the Divestiture, an after-tax loss of $37 million, or $0.61 per diluted share, for the Rationalization Charge, an after-tax charge of $15 million, or $0.24 per diluted share, for the Inventory Markup and after-tax acquisition, divestiture and integration expenses of $29 million, or $0.47 per diluted share, related to the BWI Southeast acquisition and the Divestiture.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the six months ended June 30, 2025 and 2024 was $605 million and $173 million, respectively. Operating cash flow is substantially derived from consolidated net earnings before deducting depreciation, depletion and amortization and the impact of changes in working capital requirements. Additionally, in 2024, operating cash flow reflects deducting the nonrecurring gain on the Divestiture and adding back the noncash Rationalization Charge. 2024 operating cash flow also included higher income tax payments resulting from the taxable gain associated with the Divestiture.

The Internal Revenue Service has provided certain disaster tax relief for North Carolina businesses affected by Hurricanes Debby and Helene, which allows the Company to defer estimated federal and certain state income, payroll and excise tax payments for the period from August 2024 through September 2025. The deferred obligation will be due September 25, 2025. The Company deferred income tax payments of $150 million under this provision as of June 30, 2025.

The seasonal nature of construction activity impacts the Company’s interim operating cash flow when compared with the full year. Full-year 2024 net cash provided by operating activities was $1.5 billion.

During the six months ended June 30, 2025 and 2024, the Company paid $412 million and $339 million, respectively, for additions to property, plant and equipment.

In February 2024, the Company received pretax cash proceeds of $2.1 billion from the Divestiture. On April 5, 2024, the Company used $2.05 billion of cash on hand to fund the acquisition of 20 active aggregates operations in Alabama, South Carolina, South Florida, Tennessee, and Virginia from affiliates of Blue Water Industries LLC.

The Company can repurchase its common stock through open-market purchases pursuant to authority granted by its Board of Directors or through private transactions at such prices and upon such terms as the Chief Executive Officer deems appropriate. During the first six months of 2025, the Company repurchased 910,831 shares of common stock at an average price of $494.04 and an aggregate cost of $450 million. At June 30, 2025, 11.0 million shares of common stock remain under the Company’s repurchase authorization.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility) that matures on September 17, 2025. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements.

The Company has an $800 million five-year senior unsecured revolving facility (the Revolving Facility), which matures in December 2029. The Revolving Facility requires the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined, for the trailing-twelve-month period (the Ratio) to not exceed 3.50 times as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio debt incurred in connection with certain acquisitions during the quarter or the three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 4.00 times. Additionally, if there are no amounts outstanding under the Revolving Facility and the Trade Receivable Facility, consolidated debt, including debt for which the Company is a guarantor, shall be reduced in an amount equal to the lesser of $500 million or the sum of the Company’s unrestricted cash and temporary investments, for purposes of the covenant calculation. The Company was in compliance with the Ratio at June 30, 2025. In the event of a default on the Ratio, the lenders can terminate the Revolving Facility and Trade Receivable Facility and declare any outstanding balances as immediately due.

Cash on hand, along with the Company’s projected internal cash flows and availability of financing resources, including its access to debt and equity capital markets, is expected to continue to be sufficient to provide the capital resources necessary to support anticipated operating needs, cover debt service requirements, address near-term debt maturities, meet capital expenditures and discretionary investment needs, fund certain acquisition opportunities that may arise, allow for payment of dividends for the foreseeable future and allow the repurchase of shares of the Company’s common stock. At June 30, 2025, there were no amounts outstanding under the Trade Receivable Facility or under the Revolving Facility, and the Company had $1.2 billion of unused borrowing capacity under its Revolving Facility and Trade Receivable Facility, subject to complying with the related leverage covenant. Historically, the Company has successfully extended the maturity dates of these credit facilities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The Company’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs.

Management has considered the current economic environment and its potential impact to the Company's business. Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues. Further, delays or cancellations of capital projects in the nonresidential and residential construction markets could occur if companies and consumers are unable to obtain affordable financing for construction projects or if consumer confidence is eroded by economic uncertainty.

Demand in the nonresidential and residential construction markets, which combined accounted for 60% of aggregates shipments for the six months ended June 30, 2025, is affected by interest rates. While unchanged since December 31, 2024, the target federal funds rate remains above historical levels.

Aside from these inherent risks from within its operations, the Company’s earnings are also affected by changes in short-term interest rates and changes in enacted tax laws.

Variable-Rate Borrowing Facilities. At June 30, 2025, the Company had an $800 million Revolving Facility and a $400 million Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. There were no borrowings outstanding on either facility at June 30, 2025. However, any future borrowings under the credit facilities or outstanding variable-rate debt are exposed to interest rate risk.

Pension Expense. The Company’s results of operations are affected by its pension expense. Assumptions that affect pension expense include the discount rate and, for the qualified defined benefit pension plan only, the expected long-term rate of return on assets. Therefore, the Company has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Company’s annual pension expense is discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Income Tax. Any changes in enacted tax laws, rules or regulatory or judicial interpretations, or any change in the pronouncements relating to accounting for income taxes could materially impact the Company’s effective tax rate, tax payments, cash flow, financial condition and results of operations.

Energy Costs. Energy costs, including diesel fuel, natural gas, electricity, coal and petroleum coke, represent significant production costs of the Company. The Company may be unable to pass along increases in the costs of energy to customers in the form of price increases for the Company’s products. The cement product line and Magnesia Specialties business each have varying fixed-price agreements for a portion of their 2025 energy requirements. A hypothetical 10% change in the Company’s energy prices in 2025 as compared with 2024, assuming comparable volumes, would change 2025 energy expense by $32 million.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. As of June 30, 2025, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and the operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2025. There were no changes in the Company’s internal control over financial reporting during the most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

EXHIBIT 95

MINE SAFETY DISCLOSURES

The operation of the Company’s domestic aggregates quarries and mines is subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects the Company’s quarries and mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders may be contested and appealed and, as part of that process, are often reduced in severity and amount; they are sometimes dismissed.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act), the Company is required to present information regarding certain mining safety and health citations which MSHA has issued with respect to its aggregates mining operations in its periodic reports filed with the Securities and Exchange Commission (SEC). In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the quarry or mine and types of operations (i.e., underground or surface), (ii) the number of citations issued will vary from inspector to inspector and location to location, and (iii) citations and orders can be contested and appealed, and in that process, may be reduced in severity and amount, and are sometimes dismissed.

The Company has provided the information below in response to the SEC’s rules and regulations issued under the provisions of the Dodd-Frank Act. The disclosures reflect U.S. mining operations only, as the requirements of the Dodd-Frank Act and the SEC rules and regulations thereunder do not apply to the Company’s quarries and mines operated outside the United States.

The Company presents the following items regarding certain mining safety and health matters for the three months ended June 30, 2025:

  • Total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under section 104 of the Mine Act for which the Company has received a citation from MSHA (hereinafter, “Section 104 S&S Citations”). If MSHA determines that a violation of a mandatory health or safety standard is likely to result in a reasonably serious injury or illness under the unique circumstance contributed to by the violation, MSHA will classify the violation as a “significant and substantial” violation (commonly referred to as an S&S violation). MSHA inspectors will classify each citation or order written as an S&S violation or not.

  • Total number of orders issued under section 104(b) of the Mine Act (hereinafter, “Section 104(b) Orders”). These orders are issued for situations in which MSHA determines a previous violation covered by a Section 104(a) citation has not been totally abated within the prescribed time period, so a further order is needed to require the mine operator to immediately withdraw all persons (except authorized persons) from the affected area of a quarry or mine.

  • Total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under Section 104(d) of the Mine Act (hereinafter, “Section 104(d) Citations and Orders”). These violations are similar to those described above, but the standard is that the violation could significantly and substantially contribute to the cause and effect of a safety

    Appendix 1

  • or health hazard, but the conditions do not cause imminent danger, and the MSHA inspector finds that the violation is caused by an unwarranted failure of the operator to comply with the health and safety standards.

  • Total number of flagrant violations under section 110(b)(2) of the Mine Act (hereinafter, “Section 110(b)(2) Violations”). These violations are penalty violations issued if MSHA determines that violations are “flagrant”, for which civil penalties may be assessed. A “flagrant” violation means a reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury.

  • Total number of imminent danger orders issued under section 107(a) of the Mine Act (hereinafter, “Section 107(a) Orders”). These orders are issued for situations in which MSHA determines an imminent danger exists in the quarry or mine and results in orders of immediate withdrawal of all persons (except certain authorized persons) from the area of the quarry or mine affected by its condition until the imminent danger and the underlying conditions causing the imminent danger no longer exist.

  • Total dollar value of proposed assessments from MSHA under the Mine Act. These are the amounts of proposed assessments issued by MSHA with each citation or order for the time period covered by the reports. Penalties are assessed by MSHA according to a formula that considers a number of factors, including the mine operator’s history, size, negligence, gravity of the violation, good faith in trying to correct the violation promptly, and the effect of the penalty on the operator’s ability to continue in business.

  • Total number of mining-related fatalities. Mines subject to the Mine Act are required to report all fatalities occurring at their facilities unless the fatality is determined to be “non-chargeable” to the mining industry. The final rules of the SEC require disclosure of mining-related fatalities at mines subject to the Mine Act. Only fatalities determined by MSHA not to be mining-related may be excluded.

  • Receipt of written notice from MSHA of a pattern (or a potential to have such a pattern) of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of other mine health or safety hazards under Section 104(e) of the Mine Act. If MSHA determines that a mine has a “pattern” of these types of violations, or the potential to have such a pattern, MSHA is required to notify the mine operator of the existence of such a thing.

  • Legal actions before the Federal Mine Safety and Health Review Commissions pending as of the last day of period.

  • Legal actions before the Federal Mine Safety and Health Review Commissions initiated during period.

  • Legal actions before the Federal Mine Safety and Health Review Commissions resolved during period.

The Federal Mine Safety and Health Review Commission (the Commission) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. The cases may involve, among other questions, challenges by operators to citations, orders and

Appendix 1

penalties they have received from MSHA, or complaints of discrimination by miners under Section 105 of the Mine Act. Appendix 1 shows, for each of the Company’s quarries and mines identified, as of June 30, 2025, the number of legal actions pending before the Commission, along with the number of legal actions initiated before the Commission during the quarter as well as resolved during the quarter. In addition, Appendix 1 includes a footnote to the column for legal actions before the Commission pending as of the last day of the period, which footnote breaks down that total number of legal actions pending by categories according to the type of proceeding in accordance with various categories established by the Procedural Rules of the Commission.
