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 are 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 nine months ended September 30, 2022 and 2021, 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 assets in the escrow trust account may not be used for any purpose other than to satisfy the remaining interest payments on the 2023 Notes 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 are invested in a U.S. Treasury securities fund (see Note 7) and investment returns on those trust assets are for the account of the Company (after satisfaction of all amounts payable in connection with the 2023 Notes). The Company has consolidated the trust account on its balance sheet at September 30, 2022.

Revenue Recognition

Total revenues include sales of products and services to customers, net of any discounts or allowances, and freight revenues. Product revenues are recognized when control of the promised good is transferred to the customer, 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. Freight revenues reflect delivery arranged by the Company using a third party on behalf of the customer and are recognized consistently with the timing of the product revenues.

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. For product revenues and freight revenues, customer payment terms are generally 30 days from invoice date. Customer payments for the paving operations are based on a contractual billing schedule and are due 30 days from invoice date.

Future revenues from unsatisfied performance obligations at September 30, 2022 and 2021 were $304.3 million and $183.0 million, respectively, where the remaining periods to complete these obligations ranged from less than one month to 37 months and one month to 21 months, respectively.

Service revenues for the nine months ended September 30, 2022 and 2021 were $252.1 million and $182.7 million, respectively.

Contract Balances. Costs in excess of billings relate to the conditional right to consideration for completed contractual performance and are contract assets on the consolidated balance sheets. Costs in excess of billings are reclassified to accounts receivable when the right to consideration becomes unconditional. Billings in excess of costs relate to customers invoiced in advance of contractual performance and are contract liabilities on the consolidated balance sheets. The following table presents information about the Company’s contract balances:

Business Combinations, Discontinued Operations, Divestitures and Assets and Liabilities Held for Sale

Business Combinations

In October 2021, the Company completed the acquisition of Lehigh Hanson, Inc.’s West Region business (Lehigh West Region) for $2.26 billion. The acquisition was primarily financed using proceeds from the issuance of publicly traded debt. These operations provided a new upstream, materials-led growth platform across several of the nation’s largest and fastest-growing megaregions in California and Arizona. The results from the acquired business are included in the Company’s West Group.

The Company determined the acquisition-date fair values of assets acquired and liabilities assumed. Although the initial accounting for the business combination has been recorded, these amounts are subject to change during the measurement period, which extends no longer than one year from the consummation date, based on additional reviews. Notably, during the quarter ended September 30, 2022, the Company reduced the acquisition-date fair value of intangible assets, other than goodwill, by $119.5 million; increased the acquisition-date fair value of asset retirement obligations and other liabilities assumed by $50.9 million; and increased goodwill by $171.4 million. While the determination of the acquisition-date fair values of assets acquired and liabilities assumed is substantially complete as of September 30, 2022, the measurement period remains open for asset retirement obligations and other liabilities. The Company does not expect any material measurement period adjustments to be recorded during the quarter ending December 31, 2022. Amortization of the goodwill generated by the transaction is deductible for income tax purposes.

The following is a summary of the preliminary estimated fair values of the assets acquired and liabilities assumed as of October 1, 2021 (dollars in millions):

Assets: |  |  |
Inventories |  | $ | 91.2 |
Property, plant and equipment |  |  | 849.9 |
Intangible assets, other than goodwill |  |  | 431.5 |
Goodwill |  |  | 1,213.2 |
Other assets |  |  | 54.4 |
Total assets |  |  | 2,640.2 |
Liabilities: |  |  |
Asset retirement obligations |  |  | 234.7 |
Operating and finance lease liabilities |  |  | 57.5 |
Other liabilities |  |  | 83.4 |
Total liabilities |  |  | 375.6 |
Total consideration |  | $ | 2,264.6 |

In July 2021, the Company acquired the assets of Southern Crushed Concrete (SCC) in the Houston area. SCC was a leading producer of recycled concrete, which is principally used as a base aggregates product in infrastructure, commercial and residential construction applications. The Company determined the acquisition-date fair values of the assets acquired and liabilities assumed. During the quarter ended September 30, 2022, the Company reduced the acquisition-date fair value of intangible assets, other than goodwill, by $64.0 million and increased goodwill by $64.5 million. The measurement period is closed as of September 30, 2022. Amortization of the goodwill generated by the

transaction is deductible for income tax purposes. The results from the acquired business are included in the Company’s West Group, but are immaterial for pro-forma financial statement disclosures.

In April 2021, the Company completed the acquisition of Tiller Corporation (Tiller), a leading aggregates and hot mix asphalt supplier in the Minneapolis/St. Paul area, which is one of the largest and fastest-growing midwestern metropolitan areas. The Tiller acquisition complemented the Company’s existing product offerings in the surrounding areas. Amortization of the goodwill generated by the transaction is deductible for income tax purposes. The results from the acquired business are included in the Company’s East Group, but are immaterial for pro-forma financial statement disclosures.

Discontinued Operations

Discontinued operations include the cement and California ready mixed concrete businesses acquired as part of the Lehigh West Region acquisition.

Discontinued operations include the following:

|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 30, 2022 |
|  | (Dollars in Millions) |
Total revenues |  | $ | 62.4 |  |  | $ | 268.8 |

Income tax expense |  |  | 1.3 |  |  |  | 6.5 |
Earnings from discontinued operations, net of income tax expense |  | $ | 4.1 |  |  | $ | 14.3 |

Total cash provided by operating and investing activities for the discontinued operations was $200.9 million, including $249.9 million of proceeds from divestitures and $13.2 million of cash used for capital expenditures, for the nine months ended September 30, 2022. Non-cash items related to operating and investing activities for the discontinued operations were immaterial for the nine months ended September 30, 2022.

Divestitures

On August 9, 2022, the Company announced a definitive agreement to sell the Tehachapi, California cement plant and related distribution terminals for $350.0 million in cash, subject to regulatory approval and customary closing conditions.

In June 2022, the Company completed the sale of the Redding, California cement plant, related cement distribution terminals and 14 California ready mix operations for $235.0 million in cash. In addition, on July 15, 2022, the Company sold its interest in a joint venture that operates a cement distribution terminal for $15.0 million. These businesses were previously classified as assets held for sale.

In April 2022, the Company divested its Colorado and Central Texas ready mixed concrete operations to Smyrna Ready Mix Concrete LLC. This opportunity 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 $151.9 million, which is included in Other operating income, net, for the nine months ended September 30, 2022 and is inclusive of expenses incurred due to the divestiture. The divested operations and the gain on divestiture are all reported in the West Group.

On September 29, 2022, the Company satisfied and discharged the 2023 Notes. In connection with the satisfaction and discharge, the Company irrevocably deposited with Regions Bank (the Trustee) funds in an amount sufficient to satisfy all remaining principal and interest payments on the 2023 Notes. Holders of the 2023 Notes will receive payment of principal on the scheduled maturity date of the 2023 Notes and payment of interest at the per annum rate (and on the dates) set forth in the 2023 Notes indenture. 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 in respect of 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 remain on the Company’s consolidated balance sheet at September 30, 2022 and will continue to accrete to their par value over the period until maturity in July 2023. Additionally, the related trust assets are included in Restricted investments (to satisfy discharged debt and related interest) on the Company’s consolidated balance sheet at September 30, 2022.

During the nine months ended September 30, 2022, the Company repurchased $67.7 million (par value) of its Senior Notes.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility). On September 21, 2022, the Company extended the maturity to 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, and is limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold by the Company 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 million. There were no borrowings outstanding under the Trade Receivable Facility at September 30, 2022 and December 31, 2021.

The Company has a $800 million five-year senior unsecured revolving facility (the Revolving Facility) 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). Borrowings under the Revolving Facility bear interest, at the Company’s option, at rates based upon LIBOR 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 at September 30, 2022 or December 31, 2021. 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 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 such 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 both the Revolving Facility and the Trade Receivable Facility, consolidated debt, including debt for which the Company is a guarantor (see Note 10), may 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 this covenant at September 30, 2022.

(Continued)

The Revolving Facility expires on December 21, 2026, with any outstanding principal amounts, together with interest accrued thereon, due in full on that date. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. The Company had $2.6 million of outstanding letters of credit issued under the Revolving Facility at September 30, 2022 and December 31, 2021.

7.
Financial Instruments

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

Temporary cash investments are placed primarily in money market funds, money market demand deposit accounts and Eurodollar time deposits. The Company’s cash equivalents have original 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 fair value of restricted cash approximates its carrying 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 estimated fair value of the restricted investments approximate their carrying value. The Company is restricted from accessing the investments, which will be used to settle the 2023 Notes and related interest payments.

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 September 30, 2022 and December 31, 2021. The estimated fair values of accounts receivable approximate their carrying amounts due to the short-term nature of the accounts.

Notes receivable are primarily promissory notes with customers and are not publicly traded. Management estimates that the fair value of notes receivable approximates the carrying amount.

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

The carrying values and fair values of the Company’s long-term debt were $5.04 billion and $4.23 billion, respectively, at September 30, 2022 and $5.10 billion and $5.45 billion, respectively, at December 31, 2021. The estimated fair value of the publicly-registered long-term notes was estimated using quoted market prices. The estimated fair values of other borrowings approximate their carrying amounts as the interest rates reset periodically.

8.
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 22.1% and 20.6% for the nine months ended September 30, 2022 and 2021, respectively. The higher 2022 effective income tax rate versus 2021 was driven by the impact of the divestiture of the Colorado and Central Texas ready mixed concrete businesses.

The Company records interest accrued in relation to unrecognized tax benefits as income tax expense. Penalties, if incurred, are recorded as operating expenses in the consolidated statements of earnings and comprehensive earnings.

9.
Pension and Postretirement Benefits

During the nine months ended September 30, 2022, the Company amended its qualified pension plan and provided an enhanced benefit for eligible hourly active participants who retire subsequent to April 30, 2022. The amendment required a pension remeasurement. The Company elected the use of a practical expedient to perform the pension remeasurement as of February 28, 2022, the month-end closest to the approval of the plan amendment. The discount rate for the remeasurement was 3.75% compared with 3.23% prior to the remeasurement. The enhanced benefit and remeasurement resulted in higher pension expense for full-year 2022 compared with the initial estimate of the annual pension expense for the qualified plan.

The estimated components of the recorded net periodic benefit cost (credit) for pension and postretirement benefits are as follows:

|  | Pension |  |  | Postretirement Benefits |

The service cost component of net periodic benefit (credit) cost is included in Cost of revenues – products and services and Selling, general & administrative expenses. All other components are included in Other nonoperating income, net, in the consolidated statements of earnings and comprehensive earnings.

10. Commitments and Contingencies

L egal and Administrative Proceedings

The Company is engaged in certain legal and administrative proceedings incidental to its normal business activities, including matters relating to environmental protection. 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 as a whole, based on currently available facts.

Borrowing Arrangements with Affiliate

The Company is a guarantor with an unconsolidated affiliate for a $15.0 million revolving line of credit agreement with Truist Bank that has a maturity date of March 2024, of which $3.6 million was outstanding at September 30, 2022. The affiliate has agreed to reimburse and indemnify the Company for any payments and expenses the Company may incur from this agreement. The Company holds a lien on the affiliate’s membership interest in a joint venture as collateral for payment under the revolving line of credit.

In addition, the Company has a $6.0 million interest-only loan receivable, due December 31, 2024, outstanding from this unconsolidated affiliate at September 30, 2022 and December 31, 2021. The interest rate is one-month LIBOR plus a current spread of 1.63%.

Letters of Credit

In the normal course of business, the Company provides certain third parties with standby letter of credit agreements guaranteeing payment for certain insurance claims, contract performance and permit requirements. At September 30, 2022, the Company was contingently liable for $21.8 million in letters of credit.

11. Business Segments

The Building Materials business contains two reportable segments: the East Group and the West Group. The Company also has a Magnesia Specialties segment. The Company’s evaluation of performance and allocation of resources are based primarily on earnings from operations. Consolidated earnings from operations include total revenues less cost of revenues; selling, general and administrative expenses; acquisition and integration expenses; other operating income and expenses, net; and exclude interest expense; other nonoperating income and expenses, net; and income taxes. Corporate loss from operations primarily includes depreciation; expenses for corporate administrative functions; acquisition and integration expenses; and other nonrecurring income and expenses not reported in one of the operating segments. All long-term debt and related interest expense are held at Corporate.

OVERVIEW

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. As of September 30, 2022, the Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 350 quarries, 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 has a leading aggregates position. In addition, the Company has one cement plant, cement distribution terminals and ready mixed concrete operations in California that are classified as assets held for sale and reported as discontinued operations as of and for the nine months ended September 30, 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 and 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, Iowa, Kansas, Kentucky, Maryland, Minnesota, Missouri, Nebraska, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, West Virginia, Nova Scotia and The Bahamas |  | Arizona, Arkansas, California, Colorado, Louisiana, Oklahoma, Texas, Utah, Washington and Wyoming
Product Lines |  | Aggregates and Asphalt |  | Aggregates, Cement, Ready Mixed Concrete, Asphalt and Paving Services
Facility Types |  | Quarries, Mines, Asphalt Plants and Distribution Facilities |  | Quarries, Mines, Cement Plants, Asphalt Plants, Ready Mixed Concrete Plants and Distribution Facilities
Modes of Transportation |  | Truck, Rail and Ship |  | Truck and Rail

The Building Materials business is significantly affected by weather patterns and seasonal changes. 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. Operations concentrated in the northern and midwestern United States generally experience more severe winter weather conditions than operations in the Southeast, Southwest and West. Excessive rainfall, and conversely excessive drought, 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.

(Continued)

The Company has a Magnesia Specialties business with 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 in the steel and mining industries.

CRITICAL ACCOUNTING POLICIES

The Company outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2021. There were no changes to the Company’s critical accounting policies during the nine months ended September 30, 2022.

RESULTS OF OPERATIONS

Earnings from continuing operations before interest; income taxes; depreciation, depletion and amortization; the earnings/loss from nonconsolidated equity affiliates; acquisition and integration expenses; the impact of selling acquired inventory after markup to fair value as part of acquisition accounting; and the nonrecurring gain on the divestiture of certain ready mixed concrete operations (Adjusted EBITDA) is an indicator used by the Company and investors to evaluate the Company’s operating performance from period to period. 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, earnings from operations or cash provided by operating activities. However, the Company’s management believes that Adjusted EBITDA may provide additional information with respect to the Company’s performance and is a measure used by management to evaluate the Company’s performance. Because 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.

A reconciliation of net earnings from continuing operations attributable to Martin Marietta to Adjusted EBITDA is as follows:

Adjusted consolidated earnings from operations and adjusted earnings per diluted share from continuing operations represent non-GAAP financial measures and exclude acquisition and integration expenses; the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting; and the impact of the nonrecurring gain on the divestiture of certain ready mixed concrete operations. Management presents these measures for investors to evaluate and forecast the Company’s results, as the impact of these items are nonrecurring.

Mix-adjusted average selling price (mix-adjusted ASP) excludes the impacts of product, geographic and other mix from the current-period average selling price and is a non-GAAP measure. Mix-adjusted ASP is calculated by comparing current-period shipments to like-for-like shipments in the comparable prior period. Management uses this metric to evaluate the effectiveness of the Company’s pricing increases and believes this information is useful to investors as it provides same-on-same pricing trends.

Aggregates End-Use Markets

Organic aggregates shipments to the infrastructure market remained flat, reflecting increased highway construction activity in North Carolina, Colorado, Georgia and Indiana which was offset by project delays and projects coming to completion in Texas. The infrastructure market accounted for 36% of third-quarter organic aggregates shipments.

Organic aggregates shipments to the nonresidential market increased 2%, driven by several large manufacturing, data center and energy projects in Georgia, North Carolina, Iowa and Texas. The nonresidential market represented 35% of third-quarter organic aggregates shipments.

Organic aggregates shipments to the residential market decreased 3%. Despite overall underbuilt conditions, several markets experienced a slowdown in this end use due to affordability concerns and logistical challenges. The residential market accounted for 24% of third-quarter organic aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of third-quarter organic aggregates shipments. Volumes to this end use increased 4%, driven by increased ballast shipments.

Building Materials Business

Third-quarter organic aggregates shipments were flat, due to logistical constraints and cement shortages as well as inclement weather in certain key markets. Organic pricing increased 11.9%, or 11.3% on a mix-adjusted basis, over the prior-year quarter as the Company continued to benefit from price increases. Including acquired operations, total aggregates shipments and pricing grew 5.6% and 11.6%, respectively. East Group total shipments were flat, as strong underlying demand was negatively impacted by logistical bottlenecks and weather-related disruptions. East Group pricing increased 11.5%. West Group total shipments improved 15.6%, driven primarily by contributions from acquired operations and strong Texas demand, partially offset by historically wet weather in North Texas in the month of August. West Group pricing, inclusive of acquisitions, increased 12.2%. West Group organic pricing increased 12.4%, or 13.2% on a mix-adjusted basis. Third-quarter aggregates product gross profit improved 12.8% to $330.3 million, while product gross margin declined 170 basis points to 32.5%, primarily due to increased energy, internal freight and repairs and maintenance costs.

Cement shipments of 1.1 million tons increased 2.3% driven by continued strong demand. Pricing increased 21.4%, or 20.6% on a mix-adjusted basis, following multiple price increases in Texas. Cement product gross profit grew to $67.7 million, an increase of 35.8%, and product gross margin expanded 380 basis points to 41.5%, as pricing gains more than offset higher energy costs in the period.

On an organic basis, ready mix shipments were down 16.8%, largely due to significant rainfall in Texas during August as well as the completion of certain large projects. Organic pricing increased 20.3% due to multiple price increases implemented during the year. Ready mix product revenues and gross profit from continuing operations declined 29.1% and 40.3%, respectively, driven primarily by the divestiture of the Company’s Colorado and Central Texas ready mixed concrete businesses on April 1, which was partially offset by acquired operations in Arizona.

Including contributions from the acquired West Coast operations, total asphalt shipments and pricing increased 31.3% and 26.1%, respectively. On an organic basis, total asphalt shipments and pricing increased 4.3% and 22.0%, respectively. Total asphalt and paving products and services gross profit increased to a record $50.5 million. However, continued acceleration of liquid asphalt, or bitumen, costs contributed to products and services gross margin compression of 360 basis points in the third quarter.

Magnesia Specialties Business

Magnesia Specialties third-quarter product revenues decreased 4.0% to $69.0 million, driven largely by lower demand in the steel industry for dolomitic lime products. Product gross profit declined 22.9% to $21.6 million, as higher energy costs, particularly natural gas, depressed gross margin in the quarter.

Consolidated Operating Results

Consolidated SG&A for third quarter 2022 was 5.2% of total revenues compared with 5.5% in the prior-year quarter, a 30-basis-point improvement.

Among other items, other operating income, net, includes gains and losses on the sale of assets; recoveries and write-offs related to customer accounts receivable; rental, royalty and services income; and accretion expense, depreciation expense and gains and losses related to asset retirement obligations. For the third quarter, consolidated other operating income, net, was income of $14.8 million in 2022 and $8.4 million in 2021, with the increase driven by higher gains on sales of surplus land and other assets.

Earnings from operations for the quarter were $405.9 million in 2022 compared with $356.9 million in 2021, with the increase driven by year-over-year price increases, partially offset by higher costs for energy, supplies, and freight.

Aggregates End-Use Markets

Organic aggregates shipments to the infrastructure market increased 4%, primarily driven by increased highway construction activity across many of the Company’s key markets. The infrastructure market accounted for 35% of year-to-date organic aggregates shipments.

Organic aggregates shipments to the nonresidential market increased 1%, driven by several large warehouse projects in the Central and Southwest Divisions, partially offset by several large projects in the West Division that were not replaced in the current period. The nonresidential market represented 35% of year-to-date organic aggregates shipments.

Organic aggregates shipments to the residential market remained flat compared with strong prior-year activity, but slowed in the third quarter. The residential market accounted for 25% of year-to-date organic aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of year-to-date organic aggregates shipments. Volumes to this end use increased 4%, driven by increased ballast shipments for a large project and increased agricultural lime shipments.

Building Materials Business

Year-to-date organic aggregates shipments increased 2.0%, reflecting healthy underlying public product demand partially constrained by logistics-related bottlenecks and inclement weather in certain key markets. Organic aggregates pricing increased 9.4%, or 8.6% on a mix-adjusted basis. Inclusive of acquired operations, aggregates shipments grew 8.9% and pricing also increased 8.9%, both compared with the comparable prior-year period. East Group total shipments remained flat, reflecting healthy construction activity that was offset by logistical bottlenecks and weather-related disruptions, while pricing increased 8.5%. West Group total shipments increased 25.2%, driven by robust underlying demand in Texas and shipments from acquired operations. West Group pricing, inclusive of acquisitions, increased 11.0%, while organic West Group pricing increased 11.5%, or 9.7% on a mix-adjusted basis, reflecting price increases and a larger percentage of shipments from higher-priced distribution yards. Aggregates product gross margin decreased 290 basis points to 27.9%, as the impact from year-over-year price increases were more than offset by higher costs for energy, fuel, supplies, repairs and contract services.

Texas cement shipments increased 10.3% year-to-date, supported by robust product demand. Cement pricing improved 16.1%, or 15.5% on a mix-adjusted basis, benefitting from multiple price increases. Product gross margin expanded 380 basis points to 32.1% compared with the prior-year period, as shipment and pricing growth more than offset energy and other cost headwinds.

Organic ready mixed concrete shipments decreased 5.4%. Organic pricing grew 15.2% in the first nine months of 2022 compared with 2021. Consolidated ready mixed concrete shipments decreased 17.4%, primarily reflecting the impact of divested operations, partially offset by contributions from acquired ready mix operations in Arizona, and pricing increased 9.4%. Product gross margin declined 120 basis points to 7.3%, driven primarily by higher raw material costs which more than offset price increases.

Organic asphalt shipments increased 2.6%. Organic asphalt pricing increased 19.7%. Including contributions from the acquired West Coast operations, total asphalt shipments and pricing increased 46.1% and 25.5%, respectively. Product and services gross margin decreased 630 basis points to 11.0%, driven by higher liquid asphalt and energy costs.

Magnesia Specialties Business

Magnesia Specialties product revenues increased 3.5% to $214.4 million for the nine months ended September 30, 2022, driven by robust global demand for magnesia-based chemical products. Product gross profit was $74.3 million compared with $84.4 million. Product gross margin decreased 610 basis points to 34.6%, as higher costs for energy, supplies and raw materials more than offset pricing growth.

Consolidated Operating Results

Consolidated SG&A for nine months ended September 30 was 6.3% of total revenues in 2022 and 2021.

Among other items, other operating income, net, includes gains and losses on the sale of assets; recoveries and write-offs related to customer accounts receivable; rental, royalty and services income; accretion expense, depreciation expense and gains and losses related to asset retirement obligations. For the nine months ended September 30, consolidated other operating income, net, was income of $177.4 million in 2022 and $28.2 million in 2021. The increase in other operating income, net, was primarily attributable to the $151.9 million gain on the divestiture of the Colorado and Central Texas ready mixed concrete operations. Other operating income, net, for the nine months ended September 30, 2021 included a $12.3 million gain on the sale of the Company’s former corporate headquarters.

Earnings from operations for the nine months ended September 30 were $944.4 million in 2022 compared with $763.7 million in 2021, with the increase driven by the $151.9 million gain on the divestiture of the Colorado and Central Texas

ready mixed concrete operations and year-over-year price increases, partially offset by higher costs for energy, fuel, supplies, freight and personnel.

Other nonoperating income, net, includes interest income; pension and postretirement benefit cost excluding service cost; foreign currency transaction gains and losses; equity earnings or losses from nonconsolidated affiliates; and other miscellaneous income and expenses. For the nine months ended September 30, other nonoperating income, net, was $40.1 million and $23.8 million in 2022 and 2021, respectively. The 2022 amount included a $12.0 million pretax gain related to repurchases of the Company’s debt.

Income Tax Expense

For the nine months ended September 30, 2022 and 2021, the effective income tax rates for continuing operations were 22.1% and 20.6%, respectively. The higher 2022 effective income tax rate versus 2021 was driven by the impact of the divestiture of the Colorado and Central Texas ready mixed concrete businesses.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the nine months ended September 30, 2022 and 2021 was $560.7 million and $780.3 million, respectively, driven by increased cash taxes and changes in working capital. Operating cash flow is primarily derived from consolidated net earnings before deducting depreciation, depletion and amortization, and the impact of changes in working capital. Depreciation, depletion and amortization were as follows:

|  | Nine Months Ended |
|  | September 30, |
|  | 2022 |  |  | 2021 |
|  | (Dollars in Millions) |
Depreciation |  | $ | 296.9 |  |  | $ | 262.1 |
Depletion |  |  | 45.9 |  |  |  | 29.5 |
Amortization |  |  | 37.5 |  |  |  | 28.4 |
Total |  | $ | 380.3 |  |  | $ | 320.0 |

The seasonal nature of construction activity impacts the Company’s interim operating cash flow when compared with the full year. Full-year 2021 net cash provided by operating activities was $1.14 billion.

During the nine months ended September 30, 2022 and 2021, the Company paid $309.1 million and $321.3 million, respectively, for capital investments. In October 2022, the Company entered into a commitment for 691 railcars at an aggregate value of $75.8 million.

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. The Company repurchased 418,336 shares of common stock during the first nine months of 2022 at an aggregate cost of $150.0 million. At September 30, 2022, 13,102,616 shares of common stock can be purchased under the Company’s repurchase authorization.

During the nine months ended September 30, 2022, the Company repurchased $67.7 million (par value) of its Senior Notes, resulting in a pretax gain of $12.0 million.

RESULTS OF OPERATIONS

(Continued)

On September 29, 2022, the Company satisfied and discharged its 0.650% Senior Notes due 2023 (the 2023 Notes). In connection with the satisfaction and discharge, the Company irrevocably deposited with Regions Bank (the Trustee) funds in an amount sufficient to satisfy all remaining principal and interest payments on the 2023 Notes. The funds are invested in a fund that invests exclusively in U.S. Treasury securities and are classified as Restricted investments (to satisfy discharged debt and related interest) on the consolidated balance sheet at September 30, 2022. Holders of the 2023 Notes will receive payment of principal on the scheduled maturity date and payment of interest at the per annum rate (and on the dates) set forth in the 2023 Notes indenture. 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 in respect of the 2023 Notes have been terminated, except those provisions of the indenture that, by their terms, survive the satisfaction and discharge. The 2023 Notes remain on the Company’s consolidated balance sheet at September 30, 2022 and will continue to accrete to their par value over the period until maturity in July 2023.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility). On September 21, 2022, the Company extended the maturity of the Trade Receivable Facility to September 20, 2023. 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 expires in December 2026. The Revolving Facility requires the Company’s ratio of consolidated 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, may 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 September 30, 2022.

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. There were no amounts outstanding under the Trade Receivable Facility or the Revolving Facility at September 30, 2022.

Cash on hand and restricted investments, 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 the repurchase of shares of the Company’s common stock and allow for payment of dividends for the foreseeable future. At September 30, 2022, the Company had $1,197.4 million 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.

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law in March 2020 and provided liquidity support for businesses. Through the CARES Act, the Company deferred payment of $27.6 million, representing the 6.2% employer share of Social Security taxes for the period from March 27, 2020 through December 31, 2020. Half of the deferred obligation was repaid in 2021 and the remaining half is due December 31, 2022. There will be no interest assessed on amounts deferred.

TRENDS AND RISKS

The Company outlined the risks associated with its business in its Annual Report on Form 10-K for the year ended December 31, 2021. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022, which, among other things, implements a 15% minimum tax on book income of certain large corporations, a 1% excise tax on net stock repurchases and several tax incentives to promote clean energy. Based on the Company’s current analysis of the provisions, management does not believe this legislation will have a material impact on the Company’s consolidated financial statements.

OTHER MATTERS

If you are interested in Martin Marietta stock, management recommends that, at a minimum, you read the Company’s current annual report and Forms 10-K, 10-Q and 8-K reports to the Securities and Exchange Commission (SEC) over the past year.

It em 3. Quantitative and Qualitative Disclosures About Market Risk.

The Company’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Demand in the residential and nonresidential construction markets, which combined accounted for 60% of aggregates shipments for the nine months ended September 30, 2022, is affected by interest rates. Since December 31, 2021, the Federal Reserve raised the target federal funds rate 300 basis points, and more increases are expected during the fourth quarter. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs if companies and consumers are unable to obtain financing for construction projects or if consumer confidence is eroded by economic uncertainty.

Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues.

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 September 30, 2022, the Company had an $800.0 million Revolving Facility and a $400.0 million Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. There were no borrowings outstanding on either facility at September 30, 2022. 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, 2021. The Company remeasured its qualified pension plan as of February 28, 2022, to reflect an amendment that increased the pension benefit for qualifying hourly employees. The discount rate at the remeasurement date was approximately 50 basis points higher compared with the discount rate as of December 31, 2021. As of September 30, 2022, discount rates have increased approximately 210 additional basis points since the remeasurement. Unless another event requires an interim remeasurement, the Company will next remeasure its pension obligation and funded status as of December 31, 2022. Changes in the discount rate and pension asset values will impact 2023 pension expense.

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, financial condition and results of operations.

Energy Costs. Energy costs, including diesel fuel, natural gas, electricity, and coal, represent significant production costs of the Company. The Magnesia Specialties business has fixed price agreements covering a majority of its 2022 energy requirements. On a consolidated basis, organic energy expense for the nine months ended September 30, 2022 increased approximately 59% compared with the prior-year period, related to higher prices for diesel, natural gas, electricity and gasoline in 2022. Specifically, the ongoing conflict between Russia and Ukraine has exacerbated already increased diesel prices; however, any future energy prices cannot be reliably predicted. A hypothetical increase of 59% would change consolidated organic full-year 2022 energy expense by $179.3 million as compared with 2021, assuming constant volumes. Further, the full-year 2022 impact on consolidated total profitability and margins would be greater when also considering the energy consumed by operations acquired in 2021.

Commodity Risk. Cement is a commodity, and competition is based principally on price, which is highly sensitive to changes in supply and demand. Prices are often subject to material changes in response to relatively minor fluctuations in supply and demand, general economic conditions and other market conditions beyond the Company’s control. Increases in the production capacity of industry participants or increases in cement imports tend to create an oversupply of such products leading to an imbalance between supply and demand, which can have a negative impact on product prices. There can be no assurance that prices for products sold will not decline in the future or that such declines will not have a material adverse effect on the Company’s business, financial condition and results of operations. Assuming full-year 2021 cement product revenues of $494.5 million, a hypothetical 10% change in sales price would impact full-year cement product revenues by $49.5 million.

Cement is a key raw material in the production of ready mixed concrete. The Company may be unable to pass along increases in the costs of cement and raw materials to customers in the form of price increases for the Company’s products. Assuming annual cement costs are $210 million, an approximate 2021 full year rate for ready mixed concrete continuing operations, a 10% change in cement costs, assuming constant volumes, would change the ready mixed concrete product line cost of revenues by $21.0 million. While increases in cement pricing may negatively impact the profitability of the ready mixed concrete operations, the cement business would benefit, although the positive impact may not reflect a direct correlation to the impact on the ready mixed concrete business.

The Company consumes other raw material and supply commodities in its operations, the costs of which have been negatively impacted by high inflation. The Company periodically implements price increases due to rising costs. However, there is a lag between announced price increases and the time when they are fully realized.

It em 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. As of September 30, 2022, 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 September 30, 2022. 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.
