Accounting Policies [Abstract] | |
Significant Accounting Policies | 1. Significant Accounting Policies Organization Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. As of June 30, 2023, the Company supplies aggregates (crushed stone, sand and gravel) through its network of approximate ly 350 qua rries, mines and distribution yards in 28 states, Canada and The Bahamas. Martin Marietta also provides cement and downstream products and services, namely, ready mixed concrete, asphalt and paving, in vertically-integrated structured markets where the Company also has a leading aggregates position. In addition, the Company has one cement plant that is classified as assets held for sale and reported as discontinued operations as of and for the six months ended June 30, 2023. The Company's Stockton, California cement import terminal, through the date of disposal (see Note 2), was reported as discontinued operations for the three and six months ended June 30, 2023 and 2022, and classified as assets held for sale as of December 31, 2022. 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, ready mixed concrete, asphalt and paving product lines are reported collectively as the “Building Materials” business. The Company’s Building Materials business includes two reportable segments: the East Group and the West Group. BUILDING MATERIALS BUSINESS (continuing operations only) Reportable Segments East Group West Group Operating Locations Alabama, Florida, Georgia, Indiana, Arizona, Arkansas, California, Colorado, Louisiana, Oklahoma, Texas, Utah, Product Lines Aggregates and Asphalt Aggregates, Cement, Ready Mixed Concrete, Asphalt and Paving The Company’s Magnesia Specialties business, which represents a separate reportable segment, has manufacturing facilities in Manistee, Michigan, and Woodville, Ohio. The Magnesia Specialties business produces magnesia-based chemicals products used in industrial, agricultural and environmental applications, and dolomitic lime sold primarily to customers for steel production and soil stabilization. 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 (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, 2022. 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, 2023 are not necessarily indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by U.S. 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, 2022. 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. Revenue Recognition Total revenues include sales of products and services to customers, net of discounts or allowances, if any, and freight and delivery costs billed to customers. Product revenues are recognized when control of the promised good is transferred to unaffiliated customers, typically when finished products are shipped. Intersegment and interproduct revenues are eliminated in consolidation. Service revenues are derived from the paving business and are recognized using the percentage-of-completion method under the cost-to-cost approach. When the Company arranges third-party freight to deliver products to customers, the Company has elected the delivery to be a fulfillment activity rather than a separate performance obligation. Further, the Company acts as a principal in the delivery arrangements and, as required by Accounting Standards Codification (ASC) 606, the related revenues and costs are presented gross in the consolidated statements of earnings and are recognized consistently with the timing of the product revenues. Restricted Cash At December 31, 2022, the Company had restricted cash of $ 0.8 million , which was 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 was restricted from utilizing the cash for purposes other than the purchase of qualified assets for 180 days from receipt of the proceeds from the sale of the exchanged property. Any unused cash at the end of the 180 days was transferred to unrestricted accounts of the Company and used for general corporate purposes. There was no restricted cash at June 30, 2023. 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: June 30, December 31, 2023 2022 (Dollars in Millions) Cash and cash equivalents $ 421.5 $ 358.0 Restricted cash — 0.8 Total cash, cash equivalents and restricted cash $ 421.5 $ 358.8 Restricted Investments At June 30, 2023 and December 31, 2022, the Company had $ 702.3 million and $ 704.6 million , respectively, of restricted investments, representing assets irrevocably transferred to an escrow trust account to satisfy and discharge the Company’s $ 700.0 million of 0.650 % Senior Notes due 2023 (the 2023 Notes) (see Note 4). The assets in the escrow trust account could not be used for any purpose other than to satisfy the remaining interest payments and to repay the principal amount of the 2023 Notes on the maturity date of July 15, 2023. The assets transferred to the escrow trust account were invested in a U.S. Treasury securities fund (see Note 5) and investment returns on those trust assets were for the account of the Company (after satisfaction of all amounts payable in connection with the 2023 Notes). The Company consolidated the trust account on its balance sheets at June 30, 2023 and December 31, 2022 .

Changes in net noncurrent deferred tax assets related to accumulated other comprehensive loss are as follows: Pension and Postretirement Benefit Plans Three Months Ended Six Months Ended June 30, June 30, 2023 2022 2023 2022 (Dollars in Millions) Balance at beginning of period $ 49.8 $ 80.2 $ 50.1 $ 69.7 Tax effect of other comprehensive (earnings) loss ( 0.4 ) ( 0.7 ) ( 0.7 ) 9.8 Balance at end of period $ 49.4 $ 79.5 $ 49.4 $ 79.5 Reclassifications out of accumulated other comprehensive loss are as follows: Three Months Ended Six Months Ended Affected line items in the consolidated June 30, June 30, statements of earnings 2023 2022 2023 2022 and comprehensive earnings (Dollars in Millions) Pension and postretirement Amortization of: Prior service cost $ 1.6 $ 1.2 $ 2.8 $ 2.1 Actuarial loss — 1.1 — 1.9 1.6 2.3 2.8 4.0 Other nonoperating income, net Tax effect ( 0.4 ) ( 0.6 ) ( 0.7 ) ( 1.0 ) Income tax expense Total $ 1.2 $ 1.7 $ 2.1 $ 3.0 Earnings per Common Share The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta, reduced by dividends and undistributed earnings attributable to certain of the Company’s stock-based compensation arrangements. If there is a net loss, no amount of the undistributed loss is attributed to unvested participating securities. 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. For the three and six months ended June 30, 2023 and 2022, the diluted per-share computations reflect the number of common shares outstanding including the number of additional shares that would have been outstanding if the potentially dilutive common shares had been issued. The following table reconciles the denominator for basic and diluted earnings from continuing operations per common share: Three Months Ended Six Months Ended June 30, June 30, 2023 2022 2023 2022 (In Millions) Basic weighted-average common shares outstanding 61.9 62.4 62.0 62.4 Effect of dilutive employee and director awards 0.2 0.1 0.2 0.2 Diluted weighted-average common shares outstanding 62.1 62.5 62.2 62.6 Reclassifications As of June 30, 2023, the Company combined products and services revenues and freight revenues into total revenues, and combined cost of revenues - products and services and cost of revenues - freight into total cost of revenues on the Company's consolidated statements of earnings and comprehensive earnings. Prior-year information has been reclassified to conform to the current-year presentation. The reclassifications had no impact on the Company’s previously reported results of operations, financial position or cash flows. |

Divestitures, Discontinued Operations and Assets and Liabilities Held for Sale | 2. Divestitures, Discontinued Operations and Assets and Liabilities Held for Sale Divestitures Since October 1, 2021, the California cement businesses have been classified as assets held for sale on the Company’s consolidated balance sheets; the associated financial results have been reported as discontinued operations on the consolidated statements of earnings. On May 3, 2023, the Company divested its Stockton cement import terminal in California. On June 30, 2022, the Company completed the sale of the Redding, California cement plant, related cement distribution terminals and 14 California ready mix operations for $ 235 million in cash. These businesses were previously classified as assets held for sale and their associated financial results were reported as discontinued operations. On April 1, 2022, the Company divested its Colorado and Central Texas ready-mixed concrete operations to Smyrna Ready Mix Concrete LLC. This transaction optimized the Company’s aggregates-led portfolio and improved its ability to generate more attractive margins over the long term by reducing both business cyclicality and exposure to raw material cost inflation. The transaction resulted in a pretax gain of $ 151.7 million, which was included in Other operating income, net , and was inclusive of expenses incurred due to the divestiture. The divested operations and the gain on divestiture were all reported in the West Group. Discontinued Operations On April 26, 2023, the Company terminated its agreement with CalPortland Company regarding the sale of the Company’s Tehachapi, California cement plant to CalPortland in light of the parties being unable to timely obtain the necessary approval by the U.S. Federal Trade Commission. The Company is exploring the potential sale of the Tehachapi plant to other buyers. For the three and six months ended June 30, 2023 , discontinued operations included the Company's Tehachapi, California cement plant and California ready mixed concrete operations as well as the Stockton, California cement import terminal through the May 3, 2023 divestiture. Discontinued operations for the three and six months ended June 30, 2022 also included the Company's Redding, California cement plant, related cement distribution terminals and 14 California ready mix operations that were sold in June 2022 (hereinafter, the Redding transaction). Financial results for the Company's discontinued operations are as follows: Three Months Ended Six Months Ended June 30, June 30, 2023 2022 2023 2022 (Dollars in Millions) Total revenues $ 34.5 $ 111.7 $ 59.2 $ 206.4 Pretax (loss) earnings from operations $ ( 1.4 ) $ 20.5 $ ( 18.5 ) $ 16.4 Pretax gain (loss) on divestiture and sales of assets 2.3 ( 1.0 ) 2.3 ( 1.0 ) Pretax earnings (loss) 0.9 19.5 ( 16.2 ) 15.4 Income tax expense (benefit) 0.2 6.2 ( 4.0 ) 5.2 Earnings (loss) from discontinued operations, net of $ 0.7 $ 13.3 $ ( 12.2 ) $ 10.2 Total cash provided by operating and investing activities for discontinued operations was $ 42.5 million for the six months ended June 30, 2023 , which included $ 57.5 million of proceeds from a divestiture and sales of assets and $ 3.8 million of cash used for capital expenditures. Total cash provided by operating and investing activities for the six months ended June 30, 2022 was $ 224.2 million, which included $ 235.0 million of proceeds from divestitures and $ 13.2 million of cash used for capital expenditures. Assets and Liabilities Held for Sale Assets and liabilities held for sale at June 30, 2023 primarily included a cement plant in Tehachapi, California and certain investment properties. At December 31, 2022 , assets and liabilities held for sale also included the Stockton, California cement import terminal that was sold in May 2023 and the California ready mixed concrete plants not sold as part of the Redding transaction.

In connection with the satisfaction and discharge, the Company irrevocably deposited funds with Regions Bank, as trustee under the indenture governing the 2023 Notes, in an amount sufficient to satisfy all remaining principal and interest payments on the 2023 Notes. The Company utilized existing cash resources to fund the satisfaction and discharge. As a result of the satisfaction and discharge of the 2023 Notes, the obligations of the Company under the indenture with respect to the 2023 Notes have been terminated, except those provisions of the indenture that, by their terms, survive the satisfaction and discharge. Because the discharge did not represent a legal defeasance, the 2023 Notes remained on the Company’s consolidated balance sheets at June 30, 2023 and December 31, 2022 and continued to accrete to their par value over the period until maturity. Additionally, the related trust assets were included in Restricted investments (to satisfy discharged debt and related interest) on the Company’s consolidated balance sheets at June 30, 2023 and December 31, 2022. On July 17, 2023, Regions Bank satisfied the remaining principal and interest payments and the 2023 Notes are considered repaid in full. 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 a $ 800.0 million five-year senior unsecured revolving facility (the Revolving Facility) with a maturity date of December 21, 2027 . 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. There were no borrowings outstanding under the Credit Agreement as of June 30, 2023 and December 31, 2022. Any outstanding principal amounts, together with interest accrued thereon, are due in full on that maturity date. 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, 2023 and December 31, 2022, the Company had $ 2.6 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 by the Revolving Facility, for the trailing-twelve months (the Ratio) to not exceed 3.50 x 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 4.00 x. 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 (see Note 8), shall be reduced in an amount equal to the lesser of $ 500.0 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, 2023. The Company, through a wholly-owned special-purpose subsidiary, has a $ 400.0 million trade receivable securitization facility (the Trade Receivable Facility), that matures on September 20, 2023 . The Trade Receivable Facility, with Truist Bank, Regions Bank, PNC Bank, N.A., MUFG Bank, Ltd., New York Branch, 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 asset-backed commercial paper costs of conduit lenders plus 0.65 % for borrowings funded by conduit lenders and Adjusted Term Secured Overnight Financing Rate (Adjusted Term SOFR), as defined, plus 0.7 %, subject to change in the event that this rate no longer reflects the lender’s cost of lending, for borrowings funded by all other lenders. 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 $ 500.0 million. There were no borrowings outstanding under the Trade Receivable Facility at June 30, 2023 and December 31, 2022 . |

Financial Instruments Disclosure [Abstract] | |
Financial Instruments | 5. Financial Instruments The Company’s financial instruments include temporary cash investments, restricted cash, restricted investments, accounts receivable, note 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 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. Restricted investments are held in a fund that invests solely in U.S. Treasury securities. The estimated fair value of the fund is valued at net asset value, which the fund seeks to maintain at one dollar per share. As such, the carrying value of the restricted investments approximates its fair value. The Company is restricted from accessing the investments, which will be used to settle the 2023 Notes and related interest payments. Investment returns on those trust assets are for the account of the Company if there are any remaining after satisfaction of all amounts payable in connection with the 2023 Notes. Accounts receivable are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. No single customer accounted for 10 % or more of consolidated accounts receivable at June 30, 2023 and December 31, 2022. The carrying values of accounts receivable approximate their fair values. Note receivable is a promissory note with an unconsolidated affiliate (see Note 8) and is not publicly traded. Management estimates that the carrying value of the note receivable approximates its fair value. 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 long-term debt were $ 5.04 billion and $ 4.41 billion, respectively, at June 30, 2023 and $ 5.04 billion and $ 4.36 billion, respectively, at December 31, 2022. 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. |

Income Taxes | 6. Income Taxes The 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 20.9 % and 22.6 % for the six months ended June 30, 2023 and 2022 , respectively. The higher 2022 effective income tax rate versus 2023 was driven by the impact of the divestiture of the Colorado and Central Texas ready mixed concrete businesses. |

Organization | Organization Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. As of June 30, 2023, the Company supplies aggregates (crushed stone, sand and gravel) through its network of approximate ly 350 qua rries, mines and distribution yards in 28 states, Canada and The Bahamas. Martin Marietta also provides cement and downstream products and services, namely, ready mixed concrete, asphalt and paving, in vertically-integrated structured markets where the Company also has a leading aggregates position. In addition, the Company has one cement plant that is classified as assets held for sale and reported as discontinued operations as of and for the six months ended June 30, 2023. The Company's Stockton, California cement import terminal, through the date of disposal (see Note 2), was reported as discontinued operations for the three and six months ended June 30, 2023 and 2022, and classified as assets held for sale as of December 31, 2022. 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, ready mixed concrete, asphalt and paving product lines are reported collectively as the “Building Materials” business. The Company’s Building Materials business includes two reportable segments: the East Group and the West Group. BUILDING MATERIALS BUSINESS (continuing operations only) Reportable Segments East Group West Group Operating Locations Alabama, Florida, Georgia, Indiana, Arizona, Arkansas, California, Colorado, Louisiana, Oklahoma, Texas, Utah, Product Lines Aggregates and Asphalt Aggregates, Cement, Ready Mixed Concrete, Asphalt and Paving The Company’s Magnesia Specialties business, which represents a separate reportable segment, has manufacturing facilities in Manistee, Michigan, and Woodville, Ohio.

Basis of Presentation and Use of Estimates | 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 (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, 2022. 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, 2023 are not necessarily indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by U.S. 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, 2022. 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. |
Revenue Recognition | Revenue Recognition Total revenues include sales of products and services to customers, net of discounts or allowances, if any, and freight and delivery costs billed to customers. Product revenues are recognized when control of the promised good is transferred to unaffiliated customers, typically when finished products are shipped. Intersegment and interproduct revenues are eliminated in consolidation. Service revenues are derived from the paving business and are recognized using the percentage-of-completion method under the cost-to-cost approach. When the Company arranges third-party freight to deliver products to customers, the Company has elected the delivery to be a fulfillment activity rather than a separate performance obligation. Further, the Company acts as a principal in the delivery arrangements and, as required by Accounting Standards Codification (ASC) 606, the related revenues and costs are presented gross in the consolidated statements of earnings and are recognized consistently with the timing of the product revenues. |
Restricted Cash | Restricted Cash At December 31, 2022, the Company had restricted cash of $ 0.8 million , which was 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 was restricted from utilizing the cash for purposes other than the purchase of qualified assets for 180 days from receipt of the proceeds from the sale of the exchanged property. Any unused cash at the end of the 180 days was transferred to unrestricted accounts of the Company and used for general corporate purposes. There was no restricted cash at June 30, 2023. 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: June 30, December 31, 2023 2022 (Dollars in Millions) Cash and cash equivalents $ 421.5 $ 358.0 Restricted cash — 0.8 Total cash, cash equivalents and restricted cash $ 421.5 $ 358.8 |

The assets in the escrow trust account could not be used for any purpose other than to satisfy the remaining interest payments and to repay the principal amount of the 2023 Notes on the maturity date of July 15, 2023. The assets transferred to the escrow trust account were invested in a U.S. Treasury securities fund (see Note 5) and investment returns on those trust assets were for the account of the Company (after satisfaction of all amounts payable in connection with the 2023 Notes). The Company consolidated the trust account on its balance sheets at June 30, 2023 and December 31, 2022 . |

Changes in net noncurrent deferred tax assets related to accumulated other comprehensive loss are as follows: Pension and Postretirement Benefit Plans Three Months Ended Six Months Ended June 30, June 30, 2023 2022 2023 2022 (Dollars in Millions) Balance at beginning of period $ 49.8 $ 80.2 $ 50.1 $ 69.7 Tax effect of other comprehensive (earnings) loss ( 0.4 ) ( 0.7 ) ( 0.7 ) 9.8 Balance at end of period $ 49.4 $ 79.5 $ 49.4 $ 79.5 Reclassifications out of accumulated other comprehensive loss are as follows: Three Months Ended Six Months Ended Affected line items in the consolidated June 30, June 30, statements of earnings 2023 2022 2023 2022 and comprehensive earnings (Dollars in Millions) Pension and postretirement Amortization of: Prior service cost $ 1.6 $ 1.2 $ 2.8 $ 2.1 Actuarial loss — 1.1 — 1.9 1.6 2.3 2.8 4.0 Other nonoperating income, net Tax effect ( 0.4 ) ( 0.6 ) ( 0.7 ) ( 1.0 ) Income tax expense Total $ 1.2 $ 1.7 $ 2.1 $ 3.0 |
Earnings per Common Share | Earnings per Common Share The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta, reduced by dividends and undistributed earnings attributable to certain of the Company’s stock-based compensation arrangements. If there is a net loss, no amount of the undistributed loss is attributed to unvested participating securities. 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. For the three and six months ended June 30, 2023 and 2022, the diluted per-share computations reflect the number of common shares outstanding including the number of additional shares that would have been outstanding if the potentially dilutive common shares had been issued. The following table reconciles the denominator for basic and diluted earnings from continuing operations per common share: Three Months Ended Six Months Ended June 30, June 30, 2023 2022 2023 2022 (In Millions) Basic weighted-average common shares outstanding 61.9 62.4 62.0 62.4 Effect of dilutive employee and director awards 0.2 0.1 0.2 0.2 Diluted weighted-average common shares outstanding 62.1 62.5 62.2 62.6 |

Prior-year information has been reclassified to conform to the current-year presentation. The reclassifications had no impact on the Company’s previously reported results of operations, financial position or cash flows. |
