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. 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 six months ended June 30, 2021 and 2020, the diluted per-share computations reflect the number of common shares outstanding to include the number of additional shares that would have been outstanding if the potentially dilutive common shares had been issued.

Restricted Cash

At June 30, 2021 and December 31, 2020, the Company had restricted cash of $17.2 million and $97.1 million, respectively, 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 the qualified assets for a designated period from receipt of the proceeds from the sale of the exchanged property. Any unused cash at the end of the designated period will be transferred to unrestricted accounts of the Company and can then be used for general corporate purposes. The Company has until November 22, 2021 to use the remaining restricted cash to purchase qualified assets under Section 1031.

In connection with Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230), the statement of cash flows reflects 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:

New Accounting Pronouncement

In March 2020, the FASB issued Accounting Standards Update (ASU) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”, an optional guidance for a limited period of time to ease the transition from the London interbank offered rate (“LIBOR”) to an alternative reference rate. The

For the Quarter Ended June 30, 2021

(UNAUDITED) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Continued)

ASU intends to address certain concerns relating to accounting for contract modifications and hedge accounting. These optional expedients and exceptions to applying U.S. GAAP, assuming certain criteria are met, are allowed through December 31, 2022, and any amendments should be applied on a prospective basis. The Company does not expect the transition from LIBOR to have a material impact on its consolidated financial statements.

2.	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 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 June 30, 2021 and 2020 were $215.5 million and $202.7 million, respectively, where the remaining periods to complete these obligations ranged from one month to 21 months and one month to 14 months, respectively.

Service revenues for the six months ended June 30, 2021 and 2020 were $82.2 million and $108.5 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:

(Dollars in Millions)	June 30, 2021		December 31, 2020
Costs in excess of billings	$	12.1	$	2.2
Billings in excess of costs	$	9.9	$	14.0

Revenues recognized from the beginning balance of contract liabilities for the three months ended June 30, 2021 and 2020 were $5.4 million and $4.1 million, respectively, and for the six months ended June 30, 2021 and 2020 were $9.4 million and $6.6 million, respectively.

Retainage, which primarily relates to the paving services, represents amounts that have been billed to customers but payment withheld until final acceptance by the customer of the performance obligation. Included in other current assets on the Company’s consolidated balance sheets, retainage was $8.6 million and $10.6 million at June 30, 2021 and December 31, 2020, respectively.

Policy Elections. 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 the accounting standard, the related revenues and costs are presented gross and are included in the consolidated statements of earnings.

3.	Business Combination

On April 30, 2021, the Company completed the acquisition of Tiller Corporation (Tiller), a leading aggregates and hot mix asphalt supplier in the Minneapolis/St. Paul region, one of the largest and fastest growing midwestern metropolitan areas, which complements the Company’s existing product offerings in the surrounding areas. Additionally, Tiller sells asphalt solely as a materials provider, and does not offer paving or other associated services. The Company financed the acquisition using available cash and borrowings under its credit facilities. The Company has recorded preliminary fair values of the assets acquired and liabilities assumed, which are subject to asset verification and a normal post-closing working capital adjustment. Therefore, the measurement period for accounts receivable; property, plant and equipment; intangible assets, including goodwill; and accounts payable remains open as of June 30, 2021. The impact of the acquisition is not material to the Company’s operating results; therefore, pro forma financial information is not included. The operations are reported in the Company’s East Group.

(Continued)

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility), which expires on September 22, 2021. The Trade Receivable Facility, with Truist Bank, Regions Bank, PNC Bank, N.A., The Bank of Tokyo-Mitsubishi UFJ, 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 0.85% for borrowings funded by conduit lenders and one-month LIBOR, plus 1.00%, 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. There was $240 million outstanding under the Trade Receivable Facility at June 30, 2021, and no borrowings outstanding at December 31, 2020.

The Company has a $700 million five-year senior unsecured revolving facility (the Revolving Facility) with JPMorgan Chase Bank, N.A., as Administrative Agent, Truist Bank, Deutsche Bank Securities, Inc., and Wells Fargo Bank, N.A., as Co-Syndication Agents, and the lenders party thereto. 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 Revolving Facility at June 30, 2021 or December 31, 2020. The Revolving Facility requires the Company’s ratio of consolidated debt-to-consolidated earnings before interest, taxes, depreciation and amortization (EBITDA), as defined by the Revolving Facility, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio 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 3.75x. 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 co-borrower, may be reduced by the Company’s unrestricted cash and cash equivalents in excess of $50 million, such reduction not to exceed $200 million, for purposes of the covenant calculation. The Company was in compliance with this covenant at June 30, 2021.

The Revolving Facility expires on December 5, 2024, 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 June 30, 2021 and December 31, 2020.

7.	Financial Instruments

The Company’s financial instruments include temporary cash investments, restricted cash, accounts 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.

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

Page 19 of 52

For the Quarter Ended June 30, 2021

(UNAUDITED) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Continued)

consolidated total revenues in the three-month periods ended June 30, 2021 and 2020. The estimated fair values of accounts receivable approximate their carrying amounts due to the short-term nature of the accounts.

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 $2.87 billion and $3.22 billion, respectively, at June 30, 2021 and $2.63 billion and $3.08 billion, respectively, at December 31, 2020. The estimated fair value of the publicly-registered long-term notes was estimated based on Level 2 of the fair value hierarchy 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. For the six months ended June 30, 2021, the effective income tax rate was 21.2%. For the six months ended June 30, 2020, the effective income tax rate of 20.2% reflected a $6.9 million discrete benefit from financing third-party railroad track maintenance. In exchange, the Company received a federal income tax credit and deduction.

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

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

	Pension						Postretirement Benefits
	Three Months Ended June 30,

The service cost component of net periodic benefit cost (credit) is included in Cost of revenues – products and services and Selling, general and 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

Legal 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 co-borrower with an unconsolidated affiliate for a $12.5 million revolving line of credit agreement with Truist Bank, of which $5.8 million was outstanding as of June 30, 2021 and has a maturity date of March 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, due December 31, 2022, outstanding from this unconsolidated affiliate as of June 30, 2021 and December 31, 2020. The interest rate is one-month LIBOR plus a current spread of 1.75%.

(Continued)

In the normal course of business, the Company provides certain third parties with standby letter of credit agreements guaranteeing its payment for certain insurance claims, contract performance and permit requirements. At June 30, 2021, the Company was contingently liable for $32.4 million in letters of credit, of which $2.6 million were issued under the Company’s Revolving Facility.

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-related 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-related expenses; and other nonrecurring income and expenses excluded from the Company’s evaluation of business segment performance and resource allocation. All long-term debt and related interest expense are held at Corporate.

The following table displays selected financial data for the Company’s reportable segments. Total revenues, as presented on the consolidated statements of earnings and comprehensive earnings, exclude intersegment revenues, which represent sales from one segment to another segment and are eliminated in consolidation.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

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

OVERVIEW

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 310 quarries, mines and distribution yards in 26 states, Canada and The Bahamas. In the southwestern and western United States, 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. The Company also provides asphalt in Minnesota, subsequent to a business combination in the quarter ended June 30, 2021. 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
Reportable Segments	East Group	West Group
Operating Locations	Alabama, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maryland, Minnesota, Missouri, eastern Nebraska, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, West Virginia, Nova Scotia and The Bahamas	Arkansas, Colorado, Louisiana, western Nebraska, Oklahoma, Texas, Utah, Washington and Wyoming

Product Lines	Aggregates and Asphalt	Aggregates, Cement, Ready Mixed Concrete, Asphalt and Paving

Facility Types	Quarries, Mines, Plants and Distribution Facilities	Quarries, Mines, Plants and Distribution Facilities

Modes of Transportation	Truck, Railcar and Ship	Truck and Railcar

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 and paving 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 and southwest. 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.

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, 2020. There were no changes to the Company’s critical accounting policies during the six months ended June 30, 2021.

RESULTS OF OPERATIONS

Earnings before interest; income taxes; depreciation, depletion and amortization; the earnings/loss from nonconsolidated equity affiliates; acquisition-related expenses; and the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting (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 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 attributable to Martin Marietta to Adjusted EBITDA is as follows:

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-to-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. The following reconciles reported average selling price to mix-adjusted ASP and corresponding variances.

Aggregates End-Use Markets

Aggregates shipments to the infrastructure market declined, primarily driven by weather-related project delays in key geographies and the timing of projects. The infrastructure market accounted for 34% of second-quarter aggregates shipments.

Aggregates shipments to the nonresidential market increased 17%, driven by robust demand in heavy industrial projects of scale, across our geographic footprint. The nonresidential market represented 36% of second-quarter aggregates shipments.

Aggregates shipments to the residential market increased 8%. Low available resale inventory and underbuilt conditions continue to drive robust residential construction activity. The residential market accounted for 25% of second-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of second-quarter aggregates shipments. Volumes to this end use decreased, driven by lower ballast shipments to the Class I western railroads.

Building Materials Business Product Lines

Second-quarter aggregates shipments and pricing increased 3.3% and 2.9%, respectively, compared with prior-year quarter. Organic aggregates shipments and pricing increased 1.5% and 3.4%, respectively. East Group shipments increased 7.0% reflecting strong construction activity in the Carolinas, Georgia, Florida and Maryland across all three primary end-use markets, coupled with incremental volumes from the Tiller operations, which more than offset the weather-induced project delays in the Midwest. Pricing increased 3.6% in the East Group, reflecting favorable geographic mix. West Group shipments decreased 3.6%, despite robust underlying demand, due to significant rainfall in both Texas and Colorado. West Group’s pricing increased 0.7%, reflecting a lower percentage of higher-priced commercial rail-shipped volumes. Pricing in the West Group increased 2.4% on a mix-adjusted basis. Aggregates product gross margin decreased 150 basis points to 34.0%, driven by higher diesel costs of $12.2 million and a $6.1 million increase in cost of revenues from the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting.

Cement pricing improved 6.8%, or 4.2% on a mix-adjusted basis, following annual price increases that went into effect April 1, 2021. Cement shipments decreased 1.9% despite robust demand and construction activity throughout the Texas Triangle, due to extreme precipitation from late April through mid-June. Product gross margin declined 870 basis points to 31.0%, driven by the timing of planned outages at the Hunter plant as well as higher energy and raw materials costs.

Ready mixed concrete shipments increased 8.2%, or 2.3% organically, driven by incremental volume from large projects and operations acquired in August 2020. This growth more than offset weather-related shipment declines. Pricing increased 1.2% in second quarter 2021 compared with second quarter 2020, reflecting geographic mix from a lower percentage of higher-priced Colorado shipments. Product gross margin decreased 350 basis points to 7.1%, driven primarily by higher raw material and diesel costs. Asphalt shipments increased 67.6% as incremental volume from the acquired Tiller operations more than offset weather-related shipment declines in Colorado. Pricing increased 4.9% due to price increases in Colorado as well as mix impact from higher priced Tiller asphalt sales, both contributing to asphalt and paving products and services gross margin improvement of 80 basis points.

Aggregates Product Line End-Use Markets

For the six months ended June 30, 2021, aggregates shipments to the infrastructure market accounted for 33% of aggregates volumes and declined 8% compared to the prior-year period, primarily attributable to weather-impacted project delays and timing of projects.

Aggregates shipments to the nonresidential market increased 9%, driven by robust warehouse and data center activity. The nonresidential market represented 36% of year-to-date aggregates shipments.

Aggregates shipments to the residential market increased 8%, reflecting sustained robust housing demand. The residential market accounted for 26% of year-to-date aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of year-to-date aggregates shipments. Volumes to this end use decreased 20%, driven by lower ballast shipments to Class I railroads.

Building Materials Business Product Lines

For the six months ended June 30, 2021, aggregates shipments increased 0.6%, reflecting strong construction activity in the Carolinas, Georgia, Florida and Maryland, offset by weather-induced delays in the Midwest, Texas and Colorado. Pricing increased 3.1% compared with the prior-year period which led to a 140-basis-point improvement in aggregates product gross margin to 28.7%. Aggregates shipments declined 0.4% and pricing increased 3.4% on an organic basis.

For the six months ended June 30, 2021, cement pricing increased 4.2% and shipments decreased 0.8% compared with the prior-year period. On a mix-adjusted basis, pricing increased 3.0%. Higher kiln maintenance costs, storm-related incremental costs and inefficiencies caused by weather-related shut downs coupled with an increase in energy and raw material costs contributed to a decline in cement product gross margin to 22.7%.

Ready mixed concrete shipments increased 16.1%, or 9.6% organically, driven by incremental volume from large projects and operations acquired in August 2020, partially offset by weather-related delays. Ready mixed concrete pricing for the six months ended June 30, 2021 decreased 0.2%, reflecting a lower percentage of shipments from Colorado, which carry higher average selling prices. Asphalt shipments improved 53.1% compared with the prior-year period, attributable to incremental volumes from the acquired Tiller operations. Asphalt pricing increased 5.3% reflecting increased pricing and favorable mix impact from Tiller operations.

Magnesia Specialties Business

For the six months ended June 30, 2021, Magnesia Specialties reported product revenues of $135.2 million compared with $108.8 million for the prior-year period. Lower lime and periclase shipments to the steel industry due to COVID-19-induced shutdowns of domestic auto manufacturers in the prior year resulted in lower revenues for 2020. Product gross profit was $56.3 million compared with $44.3 million, primarily driven by higher volumes and revenues. Product line

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 six months ended June 30, consolidated other operating income, net, was income of $19.8 million and expense of $8.0 million in 2021 and 2020, respectively. The 2021 amount is primarily attributable to the gains on the sales of several properties of $16.5 million. The 2020 amount reflected higher credit loss expenses and increased asset reclamation costs.

Other nonoperating income, net, includes interest income; pension and postretirement benefit cost, excluding service cost; foreign currency transaction gains and losses; equity in earnings or losses of nonconsolidated affiliates and other miscellaneous income. For the six months ended June 30, other nonoperating income, net, was $18.2 million in 2021 and $1.9 million in 2020. The 2021 amount reflected lower pension expense of $7.8 million compared with the prior year. The 2020 amount included an expense of $5.6 million to finance third-party railroad track maintenance.

Income Tax Expense

For the six months ended June 30, 2021, the effective income tax rate was 21.2%. For the six months ended June 30, 2020, the effective income tax rate of 20.2% reflected a $6.9 million discrete benefit from financing third-party railroad track maintenance. In exchange, the Company received a federal income tax credit and deduction.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the six months ended June 30, 2021 and 2020 was $441.2 million and $373.2 million, respectively.

The Company has a $700 million five-year senior unsecured revolving facility (the Revolving Facility), which expires on December 5, 2024. 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 3.50x 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 3.75x. 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 co-borrower, may be reduced by the Company’s unrestricted cash and cash equivalents in excess of $50 million, such reduction not to exceed $200 million, for purposes of the covenant calculation.

RESULTS OF OPERATIONS

(Continued)

The Ratio is calculated as debt, including debt for which the Company is a co-borrower, divided by consolidated EBITDA, as defined by the Company’s Revolving Facility, for the trailing-twelve months. Consolidated EBITDA is generally defined as earnings before interest expense, income tax expense, and depreciation and amortization expense. Additionally, stock-based compensation expense is added back and interest income is deducted in the calculation of consolidated EBITDA. During periods that include an acquisition, pre-acquisition adjusted EBITDA of the acquired company is added to consolidated EBITDA as if the acquisition occurred on the first day of the calculation period. Certain other nonrecurring items, if they occur, can affect the calculation of consolidated EBITDA.

At June 30, 2021, the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, for the trailing-twelve months was 1.95 times and was calculated as follows:

	July 1, 2020 to
	June 30, 2021
	(Dollars in Millions)
Earnings from continuing operations attributable to Martin Marietta	$	768.5
Add back:
Interest expense		112.7
Income tax expense		184.7
Depreciation, depletion and amortization expense		402.8
Stock-based compensation expense		31.1
Acquisition-related expenses		18.2
EBITDA related to acquired operations (Pre-acquisition July 1, 2020 to April 30, 2021)⁽¹⁾		34.6
Deduct:
Interest income		(0.2	)
Consolidated EBITDA, as defined by the Company’s Revolving Facility	$	1,552.4
Consolidated net debt, as defined and including debt for which the Company is a co-borrower, at June 30, 2021	$	3,027.6
Consolidated net debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, at June 30, 2021 for the trailing-twelve months EBITDA	1.95 times

⁽¹⁾ Inclusive of one-time, non-recurring and transaction-related expenses.

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 was $240 million outstanding under the Trade Receivable Facility and no borrowings under the Revolving Facility as of June 30, 2021.

Cash on hand, along with the Company’s projected internal cash flows and availability of financing resources, including its access to debt and equity capital markets, is expected to continue to be sufficient to provide the capital resources necessary to support anticipated operating needs, cover debt service requirements, address near-term debt maturities, meet capital expenditures and discretionary investment needs, fund certain acquisition opportunities that may arise, allow the repurchase of shares of the Company’s common stock and allow for payment of dividends for the foreseeable future. At June 30, 2021, the Company had $857.4 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. Further, as of June 30, 2021, the Company does not have any publicly-traded debt that matures prior to 2023.

As of June 30, 2021, the Company had restricted cash of $17.2 million for the purchase of like-kind exchange replacement assets under Section 1031 of the Internal Revenue Code and related IRS procedures (Section 1031) available to use until November 22, 2021.

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 will be due December 31, 2021 and the remaining half will be due December 31, 2022. There will be no interest assessed on amounts deferred.

TRENDS AND RISKS

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. The Company’s recent proxy statement for the annual meeting of shareholders also contains important information. These and other materials that have been filed with the SEC are accessible through the Company’s website at www.martinmarietta.com and are also available at the SEC’s website at www.sec.gov. You may also write or call the Company’s Corporate Secretary, who will provide copies of such reports.

Investors are cautioned that all statements in this Form 10-Q that relate to the future involve risks and uncertainties, and are based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. These statements, which are forward-looking statements under the Private Securities Litigation Reform Act of 1995, provide the investor with the Company’s expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “anticipate,” “expect,” “should be,” “believe,” “will,” and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of management’s forward-looking statements here and in other publications may turn out to be wrong.

The Company’s outlook is subject to various risks and uncertainties, and is based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. Factors that the Company currently believes could cause actual results to differ materially from the forward-looking statements in this Form 10-Q (including the outlook) include, but are not limited to: the ability of the Company to face challenges, including those posed by the COVID-19 pandemic and implementation of any such related response plans; fluctuations in COVID-19 cases in the United States and the extent that geography of outbreak primarily matches the regions in which the Company’s Building Materials business principally operates; the resiliency and potential declines of the Company’s various construction end-use markets; the potential negative impact of the COVID-19 pandemic on the Company’s ability to continue supplying heavy-side building materials and related services at normal levels or at all in the Company’s key regions; the duration, impact and severity of the impact of the COVID-19 pandemic on the Company, including the markets in which the Company does business, its suppliers, customers or other business partners as well as

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The COVID-19 pandemic continues to impact the global and domestic economy. The Company’s operations have to date been considered “essential” operations under applicable governmental orders that restrict activities in an effort to prevent further outbreak of COVID-19. As such, the Company is conducting business with certain modifications, including engaging medical experts to screen those who may have had COVID-19 exposure before allowing access to sites; enhancing the cleaning and disinfection of equipment and common areas, including engaging third-party specialists to disinfect work spaces; and issuing a quarantine policy requiring employees with COVID-19 symptoms to stay home for at least 10 days, among other things. The Company continues to actively monitor the situation and may take further actions that alter its business operations including any that may be required by federal, state or local authorities or that the Company determines are in the best interests of its employees, customers, suppliers, vendors, communities and other stakeholders.

Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues. Remote working trends are reducing miles driven, which is having a negative impact on various revenue streams that fund roadway projects. Further, delays or cancellations of projects in the nonresidential and residential construction markets, which combined accounted for 62% of aggregates shipments for the six months ended June 30, 2021, could occur if companies and consumers are unable to obtain financing for construction projects or if consumer confidence continues to be eroded by economic uncertainty.

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

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

Variable-Rate Borrowing Facilities. At June 30, 2021, the Company had a $700 million Revolving Facility and a $400 million Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $240 million, which was the collective outstanding balance at June 30, 2021, would increase interest expense by $2.4 million on an annual basis.

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, 2020. As of June 30, 2021, discount rates were approximately 30 basis points higher than the rate selected as of December 31, 2020, the most recent measurement date. Unless an event requires an interim remeasurement, the Company will next remeasure its pension obligation and funded status as of December 31, 2021. Changes in the discount rate and pension asset values will impact 2022 pension expense.

Energy Costs. Energy costs, including diesel fuel, natural gas, electricity, coal and liquid asphalt, represent significant production costs of the Company. The cement operations and Magnesia Specialties business have fixed price agreements covering a majority of their 2021 coal requirements. Energy expense for the six months ended June 30, 2021 increased approximately 19% compared with the prior-year period, due to increased natural gas, diesel, electricity and gasoline costs in 2021; however, any future energy prices cannot be reliably predicted. A hypothetical price change of 19% would change full year 2021 energy expense by $44 million as compared with 2020, assuming constant volumes.

FORM 10-Q

(Continued)

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 2020 cement product revenues of $453 million, a hypothetical 10% change in sales price would impact cement product revenues by $45.3 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. A hypothetical 10% change in cement costs in 2021 compared with 2020, assuming constant volumes, would change the ready mixed concrete product line cost of revenues by $25.5 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 mix business.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. As of June 30, 2021, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and the operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2021. 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.
