The Building Materials business includestwo reportable segments: East Group (comprised of the East and Southwest divisions) and West Group (comprised of the Central and West divisions). All comparative prior-period information presented in the related notes to the financial statements reflects the updated reportable segments.

The Company also operates a Specialties business, which represents a separate reportable segment. The Specialties business produces high-calcium lime, dolomitic lime and industrial mineral products, serving a diverse range of end markets, including domestic steel manufacturing, infrastructure, heavy nonresidential construction, glass manufacturing, and environmental solutions. The Specialties business also produces high-purity natural and synthetic magnesia-based products, including magnesium sulfate, magnesium oxide and magnesium hydroxide, used in environmental, industrial, agricultural, construction, consumer and specialty applications.

Basis of Presentation and Use of Estimates

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q and 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, 2025. 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 nine months ended September 30, 2026 are not necessarily indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2025 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete 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, 2025.

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.

Restricted Cash

At September 30, 2026, the Company had restricted cash of $12 million, which is invested in an account designated for the purchase of like-kind exchange replacement assets under Section 1031 of the Internal Revenue Code and related IRS procedures (Section 1031). The Company is restricted from utilizing the cash for purposes other than the purchase of qualified assets for a designated period (generally 180 days) from receipt of the proceeds from the sale of the exchanged assets. Any unused cash at the end of the designated period is transferred to unrestricted accounts of the Company and used for general corporate purposes. There wasno restricted cash at December 31, 2025.

The statements of cash flows reflect cash flow changes and balances for cash, cash equivalents and restricted cash on an aggregated basis. The following table reconciles cash, cash equivalents and restricted cash as reported on the consolidated balance sheets to the aggregated amounts presented on the consolidated statements of cash flows:

Consolidated Comprehensive Earnings and Accumulated Other Comprehensive Earnings (Loss)

Consolidated comprehensive earnings attributable to Martin Marietta are as follows:

The components of the changes in accumulated other comprehensive earnings (loss), net of tax, are as follows:

The $48 million, net of tax, other comprehensive earnings before reclassifications in the Pension and Postretirement Benefit Plans for thenine months ended September 30, 2026 reflects the remeasurement of the funded status of the Company’s qualified pension plan, required because of a curtailment event (see Note H).

Changes in net noncurrent deferred tax assets related to accumulated other comprehensive earnings (loss) are as follows:

Reclassifications out of accumulated other comprehensive earnings (loss) are as follows:

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 from continuing operations per common share:

New Accounting Pronouncement

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 certain expense captions 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.

Thenew 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 affect 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 for prior periods 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.

NOTE D: INVENTORIES, NET

NOTE E: DEBT

1 Borrowings bear interest, at the Company’s option, at either the Term Secured Overnight Financing Rate (Term SOFR Rate) or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. The Term Facility interest rate is 5.02% at September 30, 2026.

2 Borrowings bear interest, at the Company’s option, at rates based upon the Term SOFR Rate or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. The Revolving Facility interest rate is 4.80% at September 30, 2026.

3 Borrowings bear interest at a rate equal to the Adjusted Term SOFR Rate, as defined, plus 0.70%. The Trade Receivable Facility interest rate is 4.38% and 4.57% at September 30, 2026 and December 31, 2025, respectively.

Senior Notes

On August 14, 2026, the Company issued an aggregate principal amount of $5.5 billion of senior notes (collectively, the August 2026 Senior Notes). The Company used the net proceeds, together with borrowings under a $1.5 billion senior

unsecured term loan facility described below, to pay the cash consideration for the business combination with LNA (see Note B).

The August 2026 Senior Notes are carried net of original issue discount, which is being amortized by the effective interest method over the life of the issue. The principal amount, effective interest rate and maturity dates for each of the tranches are as follows:

The August 2026 Senior Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future senior indebtedness and rank senior in right of payment to the Company’s future subordinated indebtedness. The August 2026 Senior Notes of each series are redeemable at the Company's option, in whole or in part, prior to their respective par call dates, as defined, at a make-whole redemption price, and, on or after their respective par call dates and prior to their respective maturity dates, at a price equal to 100% of the principal amount. In either case, accrued and unpaid interest to, but excluding, the applicable redemption date is also payable. Upon a change-of-control repurchase event, the Company would be required to make an offer to repurchase all outstanding August 2026 Senior Notes at a repurchase price equal to 101% of the principal amount of the August 2026 Senior Notes, plus any accrued and unpaid interest.

Credit Facilities

The Company's credit facilities contain the following provisions:

On July 15, 2026, the Company entered into a Term Credit Agreement with JPMorgan Chase Bank, N.A. (JPMCB), as administrative agent, and certain financial institutions, as lenders (the Term Credit Agreement), which provides for a three-year senior unsecured term loan facility in an aggregate principal amount of $1.5 billion (the Term Facility). The Term Facility matures three years after the date on which it is funded.

On August 18, 2026, the Company entered into a Credit Agreement with JPMCB, as administrative agent, and Deutsche Bank Securities Inc., Goldman Sachs Bank USA, Morgan Stanley Senior Funding, Inc., PNC Bank, N.A., Truist Bank and Wells Fargo Bank, N.A., as syndication agents, and the issuing lenders party thereto (the Credit Agreement), which provides for a $1.5 billion five-year senior unsecured revolving facility (the Revolving Facility) with a maturity date of August 18, 2031. The Revolving Facility replaces the Company’s predecessor Credit Agreement. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. At September 30, 2026 and December 31, 2025, the Company had $3 million of outstanding letters of credit issued under the Revolving Facility and the predecessor Credit Agreement, respectively.

The Credit Agreement and Term Credit Agreement require the Company's ratio of consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization, as defined, for the trailing twelve months (the Leverage Ratio) to not exceed (a)4.75 x for the first three quarters after closing the LNA transaction, which occurred on August 21, 2026; (b)4.25 x for the next succeeding three quarters; and (c)3.75 x thereafter, provided further that the Company may exclude from the Leverage Ratio debt incurred in connection with certain acquisitions for a period of four quarters so long as the Leverage Ratio calculated without such exclusion does not exceed 4.25 x. Additionally, if there are no amounts outstanding under both the Revolving Facility and the Company’s Trade Receivable Facility, consolidated debt, as defined, is reduced for purposes of the calculation of the Leverage Ratio by the sum of the Company’s unrestricted cash and cash equivalents, such reduction not to exceed $500 million. The Company was in compliance with the Leverage Ratio at September 30, 2026.

On September 15, 2026, the Company amended its Trade Receivable Facility to decrease the facility limit from $600 million to $500 million and extended the maturity to September 15, 2027. Subject to certain conditions, including lenders providing the requisite commitments, the Trade Receivable Facility may be increased to an amount not to exceed $700 million. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements.

NOTE F: FINANCIAL INSTRUMENTS

The Company’s financial instruments include temporary cash investments, restricted cash, accounts receivable, accounts payable, Trade Receivable Facility borrowings, Term Facility borrowings, Revolving Facility borrowings and publicly traded senior notes. The carrying values of temporary cash investments, restricted cash, accounts receivable and accounts payable approximate their fair values.

The carrying value and fair value of the Company’s debt were$12.8 billion and $11.9 billion, respectively, at September 30, 2026 and$5.3 billion and$4.9 billion, respectively, at December 31, 2025. Due to its short-term nature, the carrying value of Trade Receivable Facility borrowings approximates its fair value. The estimated fair values of the Term Facility and the Revolving Facility, which represent variable-rate debt, approximate their carrying amounts as the interest rates reset periodically. The estimated fair value of the Company’s publicly traded senior notes was estimated based on Level 2 of the fair value hierarchy using observable market data.

NOTEG: 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 for continuing operations were 21.2% and 20.0% for the nine months ended September 30, 2026 and 2025, respectively.

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 nine months ended September 30, 2026, the Company's annualized effective tax rate includes the proportional amortization of these investments of $13 million, offset by other tax benefits of $13 million. For the nine months ended September 30, 2025, the Company's annualized effective tax rate included the proportional amortization of these investments of $128 million, offset by $124 million of tax credits and $15 million of other tax benefits. Unfunded commitments related to these tax equity investments as of December 31, 2025 are recorded in Unpaid commitments to limited liability companies on the consolidated balance sheet.

NOTE H: PENSION BENEFITS

In connection with the Company's divestiture of its Midlothian cement plant, related cement distribution terminals, and Texas ready mixed concrete assets (see Note B), certain employees ceased to be active participants in the Company's qualified defined benefit pension plan. This event resulted in a curtailment and required the Company to remeasure its

projected benefit obligation and plan assets. The Company elected a practical expedient and performed the remeasurement as of April 30, 2026, the month-end measurement date nearest to when the affected employees ceased to be active participants in the plan. The discount rate for the remeasurement was 6.21% compared with 6.00% prior to the remeasurement. The Company recognized a curtailment gain of $5 million during the nine months ended September 30, 2026.

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

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.

NOTE I: 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 it 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 based on currently available facts.

Other Environmental Matters

The Company’s operations are subject to and affected by federal, state and local laws and regulations relating to the environment, health and safety, and other regulatory matters. Certain of the Company’s operations may, from time to time, involve the use of substances that are classified as toxic or hazardous within the meaning of these laws and regulations. Environmental operating permits are, or may be, required for certain of the Company’s operations, and such permits are subject to modification, renewal and revocation.

The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. Despite these compliance efforts, the risk of environmental remediation liability is inherent in the operation

of the Company’s businesses, as it is with other companies engaged in similar businesses. The Company has no material provisions for environmental remediation liabilities and does not believe such liabilities will have a material adverse effect on its financial condition, results of operations or cash flow.

Letters of Credit

In the normal course of business, the Company provides certain third parties with standby letters of credit guaranteeing payment of certain insurance claims, contract performance and permit requirements. At September 30, 2026, the Company was contingently liable for $44 million in letters of credit.

Surety Bonds

At September 30, 2026, the Company was contingently liable for surety bonds required by certain governments and their related agencies. The bonds are provided in the normal course of business and are principally for certain insurance claims, construction contracts, reclamation obligations and mining permits guaranteeing the Company’s own performance. The Company has indemnified the underwriting insurance company against any exposure under the surety bonds. Based on the Company’s historical experience, no material claims have been made against these financial instruments.

NOTE J: SEGMENTS

The Building Materials business is comprised offour divisions that represent individual operating segments. These operating segments are consolidated intotwo reportable segments, the East Group and the West Group, for financial reporting purposes, as they meet the aggregation criteria (see Note A for 2026 changes to the components of the East Group and West Group reportable segments). The Specialties business represents a separate reportable segment.

The Company’s Chief Operating Decision Maker (CODM) is the Chief Operating 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 (loss) from operations, as management believes this is the best metric of segment profitability and operating performance. Segment earnings (loss) from operations is also a measure used in determining incentive compensation targets and awards. Segment earnings (loss) from operations includes revenues less cost of revenues; selling, general and administrative expenses; other operating income and expenses, net; and excludes 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 raw materials, 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 and reflect continuing operations only. 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.

1 External freight expense is a pass-through for East and West Groups

Assets employed by segment include assets directly identified with those operations, including assets held for sale. Corporate assets consist primarily of cash, cash equivalents and restricted cash; property, plant and equipment used in corporate operations; and other assets not directly identifiable with a reportable segment.

As of December 31, 2025, assets held for sale associated with discontinued operations were predominantly included in the East Group. The decrease in assets employed in the East Group as of September 30, 2026 reflects the February 2026 divestiture of the Company's Texas cement and ready mixed concrete assets and is partially offset by the assets acquired in the QUIKRETE transaction (see Note B) located within the Company's East Division. The increase in assets employed in the West Group as of September 30, 2026 is primarily due to assets acquired in the QUIKRETE transaction located within the Company's Central and West divisions, as well as the NFM acquisition. The increase in assets employed in Specialties as of September 30, 2026 is due to the assets acquired in the LNA transaction (see Note B).

The following tables display property additions for the Company’s reportable segments.

NOTE K: REVENUES AND GROSS PROFIT

The following tables, which are reconciled to consolidated amounts and reflect continuing operations only, provide revenues and gross profit (loss) by line of business: Building Materials (further divided by product line) and Specialties. Interproduct revenues represent sales from the aggregates product line to the Company's other building materials product line, namely, asphalt and paving operations and ready mixed concrete.

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, with performance periods generally ranging fromone day totwo years. Customer payments for the paving operations are generally based on contractual billing schedules and may, in certain circumstances, be contingent upon receipt of payment by the customer.

Future revenues from unsatisfied performance obligations at September 30, 2026 and 2025 were $219 million and $225 million, respectively, and the remaining periods to complete these obligations ranged fromone month to 49 months andone month to 27 months, respectively.

Service Revenues

Service revenues were $123 million and $130 million for thethree months ended September 30, 2026 and 2025, respectively, and reported in the West Group. Service revenues for the nine months ended September 30, 2026 and 2025 were $249 million and $267 million, respe ctively. Service revenues include paving operations in Colorado and British Columbia. The British Columbia paving operations were acquired on February 23, 2026. For 2025, service revenues also included the Company's California paving operations through its April 2025 divestiture date.

NOTE L: SUPPLEMENTAL CASH FLOW INFORMATION
