Organization

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 290 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’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.

Basis of Presentation

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and in Article 10 of Regulation S-X. The Company has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, the interim consolidated financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods. The consolidated results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by U.S. GAAP for complete financial statements.

consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

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

Reclassifications

As of January 1, 2021, the Company reclassified accrued income taxes from Other current liabilities to Accrued other taxes on the Company’s consolidated balance sheet. Prior-year information has been reclassified to conform to current year presentation. The reclassification had no impact on the Company’s previously reported results of operations, financial position or cash flows.

Consolidated Comprehensive Earnings/Loss and Accumulated Other Comprehensive Loss

Consolidated comprehensive earnings/loss and accumulated other comprehensive loss consist of consolidated net earnings or loss; adjustments for the funded status of pension and postretirement benefit plans; and foreign currency translation adjustments; and are presented in the Company’s consolidated statements of earnings and comprehensive earnings.

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 months ended March 31, 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.

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

Restricted Cash

As of March 31, 2021 and December 31, 2020, the Company had restricted cash of $40.9 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 June 15, 2021 to use the 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:

	March 31,		December 31,
	2021		2020
	(Dollars in Millions)
Cash and cash equivalents	$	313.9	$	207.3
Restricted cash		40.9		97.1
Total cash, cash equivalents and restricted cash presented in the consolidated statements of cash flows	$	354.8	$	304.4

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 March 31, 2021 and 2020 were $172.8 million and $212.7 million, respectively, where the remaining periods to complete these obligations ranged from one month to 19 months and one month to 21 months, respectively.

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 to the wholly-owned special-purpose subsidiary by the Company. 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 London Interbank Offered Rate, or 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 were no borrowings outstanding under the Trade Receivable Facility at March 31, 2021 or 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 March 31, 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 March 31, 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 March 31, 2021 and December 31, 2020.

5.	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

(UNAUDITED) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Continued)

consolidated total revenues in the three month period ended March 31, 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 $2.63 billion and $2.92 billion, respectively, at March 31, 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.

6.	Income Taxes

The effective income tax rate reflects the effect of federal and state income taxes on earnings and the impact of differences in book and tax accounting arising primarily from the permanent tax benefits associated with the statutory depletion deduction for mineral reserves. For the three months ended March 31, 2021, the effective income tax rate was 19.5%. For the three months ended March 31, 2020, the effective income tax rate of 0.6% 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.

7.	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 March 31,
	2021			2020			2021			2020

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) and expenses, net, in the consolidated statements of earnings and comprehensive earnings.

8.	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 $7.8 million was outstanding as of March 31, 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 March 31, 2021 and December 31, 2020. The interest rate is one-month LIBOR plus a current spread of 1.75%.

Letters of Credit

In the normal course of business, the Company provides certain third parties with standby letter of credit agreements guaranteeing its payment for certain insurance claims, contract performance and permit requirements. At March 31, 2021, the Company was contingently liable for $32.0 million in letters of credit, of which $2.6 million were issued under the Company’s Revolving Facility.

9.	Business Segments

The Building Material 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

First Quarter Ended March 31, 2021

(Continued)

RESULTS OF OPERATIONS

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.

Earnings before interest; income taxes; depreciation, depletion and amortization; and the earnings/loss from nonconsolidated equity affiliates (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 consolidated 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 all end-use markets were broadly impacted by winter weather in most of the Company’s divisions that more than offset increased residential and nonresidential construction activity in the East Division.

Aggregates shipments to the infrastructure market declined, primarily driven by weather-related project delays and the timing of projects. The infrastructure market accounted for 30% of first-quarter aggregates shipments, below the Company’s most recent ten-year annual average of 43%.

Aggregates shipments to the nonresidential market declined, driven by reduced wind energy construction in the Midwest and lower energy-sector demand in Texas and Colorado. Additionally, the completion of certain projects and the delayed start of new projects due to weather hindered shipments to this end use. Further, the COVID-19 pandemic negatively impacted office and retail development. The nonresidential market represented 37% of first-quarter aggregates shipments.

Aggregates shipments to the residential market increased 9%. Low available inventory along with low interest rates continues to drive robust residential construction activity. The residential market accounted for 27% of first-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 6% of first-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

First-quarter aggregates shipments declined 3.0% compared with prior-year quarter. East Group shipments increased 0.2%, reflecting strong residential and nonresidential construction activity in the Carolinas, Georgia, Florida and Maryland, which more than offset the Midwest’s later start to the construction season, as compared with the prior year, as well as reduced wind energy construction activity. West Group shipments decreased 7.7%, despite robust underlying demand, due to unfavorable winter weather conditions in both Texas and Colorado and reduced energy-sector demand. Pricing increased 3.4%, or 2.5% on a mix-adjusted basis. In the East Group, pricing increased 3.9%, with improvements in both the East and Central divisions. Geographic mix limited the West Group’s pricing growth to 1.9%. Aggregates product gross margin increased 490 basis points to 21.3%, driven by pricing gains and lower overall costs for contract services and internal freight.

Cement shipments increased 0.3% despite the historic winter storm that effectively shut down the Company’s cement operations for 11 days in February. Notably, the Midlothian facility in North Texas experienced double-digit shipment growth for the quarter, demonstrating the robust demand in the Dallas/Fort Worth metroplex that more than offset weather-related impacts and reduced energy-sector activity in the South and West Texas. Pricing improved 1.5%, as lower sales of higher-priced oil-well specialty cement products into West Texas disproportionately impacted overall pricing growth. On a mix-adjusted basis, cement pricing increased 2.2%. Product gross margin declined 1,160 basis points to 14.0%, driven by storm-related incremental costs and inefficiencies caused by the weather-related shut downs.

Ready mixed concrete volume increased 26.5%, led by double-digit growth in Texas from large projects and incremental volume from operations acquired in August 2020. This growth more than offset weather-related shipment declines in Colorado. Pricing declined 2.0% in the first quarter, reflecting geographic mix from a lower percentage of higher-priced Colorado shipments. Product gross margin improved 520 basis points to 8.3%, driven primarily by higher shipments and improved delivery costs. Asphalt pricing increased 7.9% while a return to more normal winter weather conditions in Colorado contributed to the 36.2% decrease in asphalt shipments.

Magnesia Specialties Business

Magnesia Specialties first-quarter product revenues increased 8.9% to $65.3 million, reflecting improved demand for chemicals and lime products. Product gross profit was $28.4 million compared with $26.1 million. Product gross margin was 43.5%, flat compared with prior-year quarter. First-quarter earnings from operations were $23.5 million in 2021 compared with $21.7 million in 2020.

Consolidated Operating Results

Consolidated SG&A for first quarter 2021 was 8.1% of total revenues compared with 8.2% in the prior-year quarter. During first-quarter 2021, the Company incurred $0.9 million in COVID-19 related expenses for enhanced personal protective equipment, as well as cleaning and sanitizing protocols across the Company’s operations, which are recorded in SG&A. Earnings from operations for the quarter were $99.3 million in 2021 compared with $57.8 million in 2020.

Among other items, other operating (income) and expenses, 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 first quarter, consolidated other operating (income) expenses, net, was income of $5.6 million in 2021 and expense of $5.6 million in 2020. The year-over-year change reflects higher gains on assets sales and lower credit losses.

Other nonoperating (income) and expenses, 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 first quarter, other nonoperating (income) and expenses, net, was income of $9.5 million and expense of $2.0 million in 2021 and 2020, respectively. The 2021 amount reflected lower pension expense of $3.3 million. Additionally, the 2020 expense included a $5.6 million charge to finance third-party railroad maintenance.

Income Tax Expense

For the three months ended March 31, 2021, the effective income tax rate was 19.5%. For the three months ended March 31, 2020, the effective income tax rate of 0.6% 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

For the three months ended March 31, cash provided by operating activities was $191.9 million in 2021 compared with $106.7 million in 2020. 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:

	Three Months Ended
	March 31,
	2021		2020
	(Dollars in Millions)
Depreciation	$	84.7	$	83.1
Depletion		6.8		7.0
Amortization		7.1		4.9
Total	$	98.6	$	95.0

The seasonal nature of construction activity impacts the Company’s quarterly operating cash flow when compared with the full year. Full-year 2020 net cash provided by operating activities was $1,050.1 million.

During the three months ended March 31, 2021, the Company paid $110.3 million for capital investments.

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 did not repurchase any shares of common stock during the first three months of 2021. At March 31, 2021, 13,520,952 shares of common stock were remaining under the Company’s repurchase authorization.

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 and complements the Company’s existing Central Division’s product offerings in the surrounding areas. The Company financed the acquisition using available cash and borrowings under its credit facilities.

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.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

First Quarter Ended March 31, 2021

(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 March 31, 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 1.74 times and was calculated as follows:

	April 1, 2020 to
	March 31, 2021
	(Dollars in Millions)
Earnings from continuing operations attributable to Martin Marietta	$	760.4
Add back:
Interest expense		115.7
Income tax expense		183.8
Depreciation, depletion and amortization expense		393.2
Stock-based compensation expense		28.4

Deduct:
Interest income		(0.3	)
Consolidated EBITDA, as defined by the Company’s Revolving Facility	$	1,481.2
Consolidated net debt, as defined and including debt for which the Company is a co-borrower, at March 31, 2021	$	2,571.7
Consolidated net debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, at March 31, 2021 for the trailing-twelve months EBITDA	1.74 times

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 borrowings under the credit facilities as of March 31, 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 when the repurchase program is resumed and allow for payment of dividends for the foreseeable future. Any future significant strategic acquisition for cash would likely require an appropriate balance of newly-issued equity with debt in order to maintain a composite investment-grade credit rating. At March 31, 2021, the Company had $1,097.4 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 March 31, 2021, the Company does not have any publicly-traded debt that matures prior to 2024.

As of March 31, 2021, the Company had restricted cash of $40.9 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 June 15, 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 the 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.

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 having non-operational personnel working remotely; limiting site access to necessary employees and critical third parties; 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 14 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 and stay-at-home orders and other guidelines 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 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 residential construction market accounted for 24% of the Company’s aggregates shipments in 2020 and 27% in the first three months of 2021.

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

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 March 31, 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. There were no borrowings outstanding on either facility at March 31, 2021.

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 March 31, 2021, discount rates were approximately 70 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, 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 three months ended March 31, 2021 decreased approximately 4% compared with the prior-year period, due to lower electricity, diesel and coal costs in 2021; however, any future energy prices cannot be reliably predicted. A hypothetical price change of 4%, which represents the quarter-over-quarter change in the Company’s energy expense, would change full year 2021 energy expense by $9 million as compared with 2020, assuming constant volumes.

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 March 31, 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 March 31, 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.
