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. Other than the required adoption of Accounting Standards Codification 842 – Leases (ASC 842), 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, 2018. 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, 2019 are not indicative of the results expected for other interim periods or the full year.

December 31, 2018 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by U.S. GAAP for complete financial statements. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

New Accounting Pronouncement

Leases

Effective January 1, 2019, the Company adopted ASC 842, which requires virtually all leases, excluding mineral interest leases, to be recorded as right-of-use (ROU) assets and lease liabilities on the balance sheet and provides guidance on the recognition of lease expense and income. ASC 842 requires the modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. It further states that an entity may use either 1) its effective date or 2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company used the effective date as the date of initial application. As such, financial information and disclosures required under ASC 842 will not be provided for dates and periods prior to January 1, 2019.

The new standard provides a number of practical expedients for transition and policy elections for ongoing accounting. The Company elected the “package of practical expedients”, which permits the Company to not reassess its prior conclusions about lease identification, lease classification and initial direct costs. The Company elected the practical expedients pertaining to the use of hindsight and to land easements. Applying the hindsight practical expedient resulted in longer lease terms for many leases. The standard provides policy election options for recognition exemption for short-term leases and separation of lease and non-lease components. The Company elected the short-term lease recognition exemption and elected not to separate lease and non-lease components for all underlying asset classes with the exceptions of railcars and fleet vehicle leases. The Company determines lease and non-lease components based on observable information, including rates provided by the lessor.

The adoption of ASC 842 resulted in the recognition of ROU assets and lease liabilities of $502.5 million and $501.6 million, respectively, for operating leases and $10.9 million and $12.1 million, respectively, for finance leases. The adoption did not have a material impact on the Company’s consolidated statement of earnings or consolidated statement of cash flows.

Subsequent to the date of adoption, the Company determines if a contract is or contains a lease at inception of the agreement. Operating and finance leases are recognized as ROU assets and the related obligations are recognized as current or noncurrent liabilities on the Company’s consolidated balance sheets. Leases with an initial lease term of one year or less are not recorded on the balance sheet.

ROU assets, which represent the Company’s right to use an underlying asset, and lease liabilities, which represent the Company’s obligation to make lease payments arising from the lease, are recognized based on the present value of the future lease payments over the lease term at commencement date. The ROU asset also includes any lease payments made at or before commencement date and any initial direct costs incurred and excludes lease incentives. Certain of the Company’s leases contain renewal and/or termination options. The Company recognizes renewal or termination options as part of its ROU assets and lease liabilities when the Company has the unilateral right to renew or terminate and it is reasonably certain these options will be exercised. The Company determines the present value of lease payments based on the implicit rate, which may be explicitly stated in the lease if available or the Company’s estimated collateralized incremental borrowing rate based on the term of the lease. For operating leases, lease expense is recognized on a straight-line basis over the lease term.

(Continued)

Some leases require the Company pay non-lease components, which may include taxes, maintenance, insurance and certain other expenses applicable to the leased property, and are primarily considered variable costs. The Company generally accounts for lease and non-lease components as a single amount. However, for railcars and fleet vehicle leases, the Company separately accounts for the lease and non-lease components.

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; foreign currency translation adjustments; and the amortization of the value of terminated forward starting interest rate swap agreements into interest expense, 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 Materials, Inc. 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

(Continued)

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, 2019 and 2018, 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:

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 revenue-cost approach. Freight revenues reflect delivery arranged by the Company using a third party on behalf of the customer and are recognized consistent 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 20 months. 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, 2019 and 2018 were $149.4 million and $88.1 million, respectively, where the remaining periods to complete these obligations ranged from one month to 21 months and one month to 20 months, respectively.

Service revenues, which include paving operations located in Colorado, were $9.9 million and $11.1 million for the three months ended March 31, 2019 and 2018, 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 Thousands) |  | March 31, 2019 |  | December 31, 2018 |
Costs in excess of billings |  | $ | 2,238 |  | $ | 1,975 |
Billings in excess of costs |  | $ | 5,814 |  | $ | 6,743 |

Revenues recognized from the beginning balance of contract liabilities for the three months ended March 31, 2019 and 2018 were $3.8 million and $4.2 million, respectively.

Retainage, which primarily relates to the paving services, represents amounts that have been billed to customers but payment withheld until final acceptance of the performance obligation by the customer. Included on the Company’s consolidated balance sheets, retainage was $5.4 million and $7.5 million at March 31, 2019 and December 31, 2018.

Warranties. The Company’s construction contracts generally contain warranty provisions typically for a period of nine months to one year after project completion and cover materials, design or workmanship defects. Historically, the Company has not experienced material costs for warranties. The ready mixed concrete product line carries longer warranty periods, for which the Company has accrued an estimate of warranty cost based on experience with the type of work and any known risks relative to the project. In total, warranty costs were not material to the Company’s consolidated results of operations for the three months ended March 31, 2019 and March 31, 2018.

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.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility). The Trade Receivable Facility, with SunTrust 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 one-month London Interbank Offered Rate, or LIBOR, plus 0.725%, subject to change in the event that this rate no longer reflects the lender’s cost of lending. The Trade Receivable Facility, which contains a cross-default provision to the Company’s other debt agreements, matures on September 25, 2019.

The Company has a $700 million five-year senior unsecured revolving facility (the Revolving Facility), which expires on December 5, 2023, with JPMorgan Chase Bank, N.A., as Administrative Agent, Branch Banking and Trust Company (BB&T), Deutsche Bank Securities, Inc., SunTrust Bank 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. 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 3.50 x 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 3.75 x. Additionally, if no amounts are outstanding under both 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 Ratio at March 31, 2019.

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 $2.3 million of outstanding letters of credit issued under the Revolving Facility at March 31, 2019 and December 31, 2018.

The Floating Senior Rate Notes due 2019 are classified as noncurrent long-term debt on the consolidated balance sheets as of March 31, 2019 and December 31, 2018 as the Company has the ability and intent to refinance the notes on a long-term basis.

5. | Financial Instruments

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

Cash equivalents 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.

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 total revenues. The estimated fair values of accounts receivable approximate their carrying amounts due to the short-term nature of the receivables.

Notes receivable are not publicly traded. Management estimates that the fair value of notes receivable approximates the carrying amount due to the short-term nature of the receivables.

Accounts payable represent amounts owed to suppliers and vendors. The estimated fair value of accounts payable approximates its 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 $3.16 billion and $3.13 billion, respectively, at March 31, 2019 and $3.12 billion and $3.01 billion, respectively, at December 31, 2018. 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 value 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 from the net permanent tax benefits associated with the statutory depletion deduction for mineral reserves. Additionally, for the three months ended March 31, 2019, the effective income tax rate includes a $13.2 million discrete benefit from a change in the tax status of a subsidiary from a partnership to a corporation, contributing to an overall tax benefit of $5.0 million.

8. | Commitments and Contingencies

Legal and Administrative Proceedings

The Company is engaged in certain legal and administrative proceedings incidental to its normal business activities. In the opinion of management and counsel, based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings, including those pertaining to environmental matters, relating to the Company and its subsidiaries, will have a material adverse effect on the overall results of the Company’s operations, its cash flows or its financial position.

Borrowing Arrangements with Affiliate

The Company is a co-borrower with an unconsolidated affiliate for a $15.5 million revolving line of credit agreement with BB&T, of which $12.8 million was outstanding as of March 31, 2019 and has a maturity date of March 2020. 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, 2019 and December 31, 2018. 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, 2019, the Company was contingently liable for $36.1 million in letters of credit, of which $2.3 million were issued under the Company’s Revolving Facility.

Employees

The Company maintains collective bargaining agreements relating to the union employees within the Building Materials business and Magnesia Specialties segment. Of the Magnesia Specialties segment, 100% of its hourly employees are represented by labor unions. The Manistee collective bargaining agreement expires in August 2019. The Woodville collective bargaining agreement expires June 2022.

9. | Business Segments

The Building Materials business contains three reportable business segments: Mid-America Group, Southeast Group and 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, net; other operating income and expenses, net; and exclude interest expense; other nonoperating income and expenses, net; and taxes on income. Corporate loss from operations primarily includes depreciation on capitalized interest; unallocated expenses for corporate administrative functions; acquisition-related expenses, net; and other nonrecurring income and expenses excluded from the Company’s evaluation of business segment performance and resource allocation. All debt and related interest expense are held at Corporate.

The following table displays selected financial data for the Company’s reportable business segments. The Bluegrass Materials Company (Bluegrass) operations, acquired in April 2018, are located in the Mid-America Group and Southeast Group. Total revenues, as well as the consolidated statements of earnings and comprehensive earnings, exclude intersegment revenues which represent sales from one segment to another segment, which are eliminated.

In April 2018, the Company acquired Bluegrass, the largest privately-held, pure-play aggregates company in the United States for $1.62 billion. These operations complement the Company’s existing southeastern footprint in its Mid-America and Southeast Groups and provide new growth platforms within Maryland and Kentucky.

The Company determined fair values of the assets acquired and liabilities assumed. Although 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, such as completion of deferred tax estimates based on the determination of the historic tax basis in assets acquired. Specific accounts subject to ongoing purchase accounting adjustments include goodwill and deferred income tax liabilities, net. Therefore, the measurement period remains open as of March 31, 2019. The following is a summary of the preliminary estimated fair values of the assets acquired and the liabilities assumed (dollars in thousands):

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 more than 300 quarries, mines and distribution yards to its customers in 31 states, Canada, the Bahamas and the Caribbean Islands. In the western United States, Martin Marietta also provides cement and downstream products, namely, ready mixed concrete, asphalt and paving services, 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 conducts its Building Materials business through three reportable business segments: Mid-America Group, Southeast Group and West Group.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

First Quarter Ended March 31, 2019

(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 and year-to-date results are not indicative of expected performance for other interim periods or the full year.

Earnings before interest, income taxes, depreciation and amortization (EBITDA) is a widely accepted financial indicator of a company’s ability to service and/or incur indebtedness. EBITDA is not defined by generally accepted accounting principles and, as such, should not be construed as an alternative to net earnings, operating earnings or operating cash flow. However, the Company’s management believes that EBITDA may provide additional information with respect to the Company’s performance or ability to meet its future debt service, capital expenditures or working capital requirements. Because EBITDA excludes some, but not all, items that affect net earnings and may vary among companies, EBITDA as presented by the Company may not be comparable to similarly titled measures of other companies.

A reconciliation of net earnings attributable to Martin Marietta Materials, Inc. to consolidated EBITDA is as follows:

(2) Heritage aggregates operations exclude acquisitions that have not been included in prior-year operations for the comparable period.

(3) 2018 shipments include the Forsyth, Georgia operation, which was divested in April 2018.

(4) Total aggregates operations include acquisitions from the date of acquisition and divestitures through the date of disposal.

First-quarter operating results demonstrate the robust underlying demand that was masked in 2018 by weather, contractor capacity and logistics disruptions. While winter weather traditionally limits the ability of outdoor contractors to perform work, the Company experienced relatively better weather during the first three months of 2019. This allowed contractors to begin addressing backlogs with an earlier-than-normal start to the construction season. The notable exception was in the Company’s second-largest state by revenues, Colorado, which experienced one of its harshest winters on record, delaying the onset of meaningful construction activity.

Aggregates shipments to the infrastructure market increased 2% as modestly improved weather, particularly in the Southeast, allowed contractors to advance transportation-related projects earlier in the construction season. Following more than a decade of underinvestment, management remains confident that infrastructure demand is poised for meaningful growth. Funding provided by the Fixing America’s Surface Transportation Act (FAST Act), combined with

numerous state and local transportation initiatives, has resulted in an acceleration in lettings and contract awards in key states, including Texas, Colorado, North Carolina, Georgia and Florida. For the quarter, the infrastructure market represented 33% of aggregates shipments, which is below the Company’s most recent ten-year average of 46% but consistent with first-quarter historical trends.

Aggregates shipments to the nonresidential market increased 33%, driven by both commercial and heavy industrial construction activity. The Company continued to benefit from robust distribution center, warehouse, data center and wind turbine projects in key geographies, including Texas, the Carolinas, Georgia and Iowa. The nonresidential market represented 37% of first-quarter aggregates shipments.

Aggregates shipments to the residential market increased 8%, driven by weather-deferred homebuilding activity in the Carolinas, Georgia and Florida. Despite the recent slowdown in housing unit starts at the national level, the residential construction outlook across the Company’s geographic footprint remains positive for both single- and multi-family housing, driven by favorable demographics, job growth, land availability, steady interest rates and efficient permitting. On a national level, housing starts remain below the 50-year annual average of 1.5 million despite notable population gains. The residential market accounted for 23% of first-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 7% of first-quarter aggregates shipments. Volumes to this sector decreased 9%, driven by reduced agricultural lime shipments from a depressed farm economy. Additionally, ballast shipments declined due to lower maintenance spending by western Class I railroads.

The average selling price by product line for the Building Materials business is as follows:

Cement shipments and pricing increased 7.3% and 3.8%, respectively, as these operations benefitted from solid underlying demand in Texas, a new Houston-area sales yard and enhanced product line. Extended maintenance outages, including the acceleration of maintenance activities originally planned for later in the year, and higher transportation costs contributed to the 1,270-basis-point reduction in product gross margin to 13.9%.

Ready mixed concrete shipments decreased 3.8%, driven by cold and wet winter weather in Colorado. Overall, ready mixed concrete prices improved 0.5% for the quarter, led by a 3.0% increase in Colorado. Restructuring initiatives implemented in 2018 have improved profitability for the Southwest ready mixed concrete business despite relatively flat shipments. Colorado asphalt shipments declined while pricing improved 3.9%.

Magnesia Specialties Business

Magnesia Specialties reported record first-quarter total products revenue of $69.2 million, an increase of 6.6%, compared with $64.9 million, attributable to continued benefit from strong domestic steel production and increased global demand for magnesia chemical products. Products gross profit was $26.6 million compared with $25.1 million. Product gross margin was relatively flat at 38.5% as pricing gains and production efficiencies were offset by higher costs for supplies and contract services. Earnings from operations were $22.6 million compared with $21.2 million.

(1) | Inclusive of cost increases/decreases, product and geographic mix and other operating impacts

Aggregates product gross margin increased 550 basis points to 18.0%, reflecting improved operating leverage from increased shipment and production levels. Extended cement maintenance outages, including the acceleration of maintenance activities originally planned for later in the year, and higher rail freight costs contributed to the 1,270-basis-point reduction in product gross margin to 13.9%.

Consolidated Operating Results

Consolidated SG&A was 8.3% of total revenues compared with 8.7% in the prior-year quarter. Earnings from operations for the quarter were $69.2 million in 2019 compared with $39.1 million in 2018.

Among other items, other operating income (expenses), net, includes gains and losses on the sale of assets; recoveries and writeoffs 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 $4.8 million in 2019 and expense of $0.5 million in 2018. The 2019 amount reflects the reversal of a $4.2 million purchase accounting accrual related to the Texas Industries, Inc. acquisition and higher gains on the sales of assets.

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 first quarter, other nonoperating income, net, was $1.6 million and $8.5 million in 2019 and 2018, respectively. The decrease in 2019 is primarily due to higher interest income in 2018.

Income Tax Benefit

For the three months ended March 31, 2019, the effective income tax rate includes a $13.2 million discrete benefit from a change in the tax status of a subsidiary from a partnership to a corporation, contributing to an overall tax benefit of $5.0 million.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the three months ended March 31 was $117.9 million in 2019 compared with $105.0 million in 2018. 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, |
|  | 2019 |  |  | 2018 |
|  | (Dollars in Thousands) |
Depreciation |  | $ | 78,069 |  |  | $ | 69,151 |
Depletion |  |  | 5,925 |  |  |  | 3,141 |
Amortization |  |  | 5,217 |  |  |  | 4,529 |
|  | $ | 89,211 |  |  | $ | 76,821 |

The seasonal nature of construction activity impacts the Company’s quarterly operating cash flow when compared with the full year. Full-year 2018 net cash provided by operating activities was $705.1 million.

During the three months ended March 31, 2019, the Company paid $130.1 million for capital investments. Full-year capital spending is expected to range from $350 million to $400 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 did not repurchase any shares of common stock during the first three months of 2019. At March 31, 2019, 14,147,751 shares of common stock were remaining under the Company’s repurchase authorization.

The $700 million 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 $400 million 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 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 for continuing

operations. 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, 2019, the Company’s ratio of consolidated debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, for the trailing-twelve months was 2.71 times and was calculated as follows:

|  | April 1, 2018 to |

Consolidated net debt, as defined and including debt for which the Company is a co-borrower, at March 31, 2019 |  | $ | 3,185,353 |
Consolidated debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, at March 31, 2019 for the trailing-twelve months EBITDA |  | 2.71 times |

The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. 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. Outstanding amounts on the Trade Receivable Facility have been classified as a current liability on the Company’s consolidated balance sheet.

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. 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, 2019, the Company had

$667.7 million of unused borrowing capacity under its Revolving Facility and Trade Receivable Facility, subject to complying with the related leverage covenant. The Revolving Facility and Trade Receivable Facility expire on December 5, 2023 and September 25, 2019, respectively.

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, 2018. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK

The Company remains confident in its previously announced full-year outlook. The Company’s geographic footprint has attractive underlying market fundamentals, including notable employment gains, population growth and superior state fiscal health – all attributes promoting steady and sustainable construction growth. Supported by robust underlying demand and third-party forecasts, the Company believes the current construction cycle will continue for the foreseeable future and expand further this year for each of the Company’s three primary construction end-use markets.

Based on current trends and expectations, management has reaffirmed its full-year guidance. Aggregates shipments by end-use market compared with 2018 levels are as follows:

| • | Infrastructure shipments to increase in the high-single digits.

| • | Nonresidential shipments to increase in the mid- to high-single digits.

| • | Residential shipments to increase in the mid-single digits.

| • | ChemRock/Rail shipments to be up slightly.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

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.

Management has considered the current economic environment and its potential impact to the Company’s business. Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal and state budget and deficit issues. Further, delays or cancellations of capital 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.

Demand in the residential construction market is affected by interest rates. The Federal Reserve did not change interest rates during the quarter ended March 31, 2019. The federal funds rate at March 31, 2019 was 2.4%. The residential construction market accounted for 22% of the Company’s aggregates product line shipments in 2018.

Aside from these inherent risks from within its operations, the Company’s earnings are also affected by changes in short-term interest rates. However, rising interest rates are not necessarily predictive of weaker operating results. Historically, the Company’s profitability increased during periods of rising interest rates. In essence, the Company’s underlying business generally serves as a natural hedge to rising interest rates.

Variable-Rate Borrowing Facilities. At March 31, 2019, the Company had a $700 million Revolving Facility and a $400 million Trade Receivable Facility. The Company also has $600 million variable-rate senior notes. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $1.03 billion, which was the collective outstanding balance at March 31, 2019, would increase interest expense by $10.3 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, 2018.

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 100% of its 2019 coal requirements. Energy costs for the three months ended March 31, 2019 increased approximately 6% over the prior-year period. A hypothetical 6% change in the Company’s energy prices for the full year 2019 as compared with 2018, assuming constant volumes, would change full year 2019 energy expense by $17.0 million.

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 total revenues for cement for full-year 2019 of $420 million to $450 million, a hypothetical 10% change in sales price would impact net sales by $42.0 million to $45.0 million.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. As of March 31, 2019, 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, 2019.

Changes in Internal Control Over Financial Reporting. Beginning January 1, 2019, the Company implemented Accounting Standard Codification 842, Leases (ASC 842). Although the adoption of the new accounting standard did not materially impact its Consolidated Statement of Earnings and Comprehensive Earnings or Consolidated Statement of Cash Flows for the three months ended March 31, 2019, the Company implemented changes to its internal controls related to the implementation of ASC 842. These changes included a comprehensive lease scoping analysis to identify and evaluate each of its leases and an implementation of a new lease accounting application to calculate values for its right-of-use assets and lease liabilities. There were no other 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.
