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. Other than the required adoption of two new accounting pronouncements described below, 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, 2017. In the opinion of management, the interim consolidated financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods. The consolidated results of operations for the three- and nine-months ended September 30, 2018 are not indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2017 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, 2017.

New Accounting Pronouncements

Revenue from Contracts with Customers

Effective January 1, 2018, the Company adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which changes the evaluation and accounting for revenue recognition under contracts with customers and enhances financial statement disclosures. The Company implemented ASU 2014-09 using the modified retrospective approach. The adoption had an immaterial impact on the Company’s financial position and results of operations but required new disclosures (see Note 2).

Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments

Effective January 1, 2018, the Company adopted ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15), which provides clarification or additional guidance on certain transactions and its classification on the statement of cash flows on a retrospective basis. The adoption had an immaterial impact on the Company’s statement of cash flows.

Pending Accounting Pronouncement

Lease Standard

In February 2016, the Financial Accounting Standards Board (FASB) issued a new accounting standard, Accounting Standards Codification 842 – Leases (ASC 842), intending to improve financial reporting of leases and to provide more transparency into off-balance sheet leasing obligations. The guidance requires virtually all leases, excluding mineral interest leases, to be recorded as right-to-use assets and lease liabilities on the balance sheet and provides guidance on the recognition of lease expense and income. Effective January 1, 2019, with early adoption permitted, ASC 842 requires the modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. 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 will adopt the new standard effective January 1, 2019 and will use the effective date as the date of initial application. As such, financial information will not be updated 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 expects to elect 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 plans to elect the practical expedients pertaining to the use of hindsight and to land easements. The standard provides policy election options for recognition exemption for short-term leases and separation of lease and non-lease components. The Company will elect the short-term lease recognition exemption and expects to elect not to separate lease and non-lease components for all underlying asset classes with the exceptions of railcars and fleet leases.

Although the Company has not determined the full impact of ASC 842, the Company expects the adoption of ASC 842 to have a material impact on its financial statements, specifically right-to-use assets and lease liabilities on the balance sheet and note disclosures pertaining to leasing activities.

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 participating securities. The denominator for basic earnings per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings per common share are computed assuming that the weighted-average number of common shares is increased by the conversion, using the treasury stock method, of awards to be issued to employees and nonemployee members of the Company’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive. For the three- and nine-months ended September 30, 2018 and 2017, 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.

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. Under the revenue-cost approach, recognized contract revenue is determined by multiplying the total estimated contract revenue by the estimated percentage of completion. Contract costs are recognized as incurred. The percentage of completion is determined on a contract-by-contract basis using project costs incurred to date as a percentage of total estimated project costs. The Company believes the revenue-cost approach is appropriate as the use of asphalt in a paving contract is relatively consistent with the performance of the paving service. Paving contracts, notably with governmental entities, may contain performance bonuses based on quality specifications. Given the uncertainty of meeting the criteria until the performance obligation is completed, performance bonuses are recognized as revenues when and if determined to be achieved. Performance bonuses are not material to the Company’s consolidated results of operations for the three- and nine-months ended September 30, 2018 and 2017. 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 September 30, 2018 and 2017 were $111,721,000 and $107,953,000, respectively, where the remaining periods to complete these obligations ranged from one month to 27 months and one month to 21 months, respectively.

Sales Taxes. The Company is deemed to be an agent when collecting sales taxes from customers. Sales taxes collected are initially recorded as liabilities until remitted to taxing authorities and are not reflected in the consolidated statements of earnings as revenues and expenses.

Revenue by Category. The following table presents the Company’s total revenues by category for each reportable segment:

Services revenues, which include paving operations located in Colorado, were $162,944,000 and $179,553,000 for the nine-months ended September 30, 2018 and 2017, 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)	September 30, 2018		December 31, 2017		September 30, 2017
Costs in excess of billings	$	5,581	$	1,310	$	8,727

2.	Revenue Recognition (continued)

Revenues recognized from the beginning balance of contract liabilities for the three-months ended September 30, 2018 and 2017 were $6,203,000 and $4,439,000, respectively, and for the nine-months ended September 30, 2018 and 2017 were $6,816,000 and $8,231,000, 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 $8,733,000, $9,029,000 and $7,680,000 at September 30, 2018, December 31, 2017 and September 30, 2017, respectively.

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- and nine-months ended September 30, 2018 and 2017.

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 27, 2018, the Company successfully completed its acquisition of Bluegrass Materials Company (Bluegrass), the largest privately-held, pure-play aggregates company in the United States. The final purchase price was $1,617,357,000, inclusive of the working capital true up. Bluegrass’ operations include 23 active sites with more than 125 years of reserves, collectively, in Georgia, South Carolina, Tennessee, Maryland, Kentucky and Pennsylvania. 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 reached an agreement with the U.S. Department of Justice (DOJ), approved by the federal district court for the District of Columbia, which resolved all competition issues with respect to the acquisition. Under the terms of the agreement with the DOJ, Martin Marietta divested its heritage Forsyth aggregates quarry north of Atlanta, Georgia, and the legacy Bluegrass Beaver Creek aggregates quarry in western Maryland. In connection with the sale of its Forsyth quarry, the Company recognized a pretax gain of $14,785,000, which is included in acquisition-related expenses, net, in the consolidated statements of earnings and comprehensive earnings. There was no gain or loss on the Beaver Creek divestiture.

The Bluegrass acquisition was a stock transaction wherein the Company acquired 100% of the voting interest of the owners. The Company acquired accounts receivable; inventories; property, plant and equipment, which primarily consists of mineral reserves; intangible assets; prepaid and other assets; and assumed accounts payable; accrued liabilities and deferred tax liabilities, net. The Company did not assume any of Bluegrass’ outstanding debt.

3.	Business Combination (continued)

The Company has determined preliminary 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 consummation date based on additional reviews, such as asset verification and 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, but are not limited to, property, plant and equipment; goodwill; and deferred income tax liabilities. Therefore, the measurement period remains open as of September 30, 2018. The following is a summary of the estimated fair values of the assets acquired and the liabilities assumed (dollars in thousands).

Assets:
Cash	$	1,159
Receivables		25,479
Inventory		46,156
Other current assets		1,029
Property, plant and equipment		1,522,386
Intangible assets, other than goodwill		19,125
Goodwill		239,360
Total assets		1,854,694

Liabilities:
Accounts payable and accrued expenses		17,893
Deferred income tax liabilities, net		210,443
Noncontrolling interest		9,001
Total liabilities		237,337

Total consideration	$	1,617,357

Goodwill represents the excess purchase price over the fair values of assets acquired and liabilities assumed and reflects projected operating synergies from the transaction, including expected overhead savings. It has not yet been determined if any of the goodwill generated by the transaction will be deductible for income tax purposes.

Total revenues and earnings from operations attributable to acquired operations included in the consolidated earnings statements for the three-months ended September 30, 2018 were $68,656,000 and $11,531,000, respectively, and for the nine-months ended September 30, 2018 were $115,007,000 and $18,276,000, respectively.

Acquisition-related expenses were $89,000 and $27,710,000 for the three- and nine-months ended September 30, 2018, respectively.

On April 17, 2018, the Company, through a wholly-owned special-purpose subsidiary, increased its trade receivable securitization facility (the Trade Receivable Facility) to $400,000,000. 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, of $465,217,000, $338,784,000 and $402,754,000 at September 30, 2018, December 31, 2017 and September 30, 2017, respectively. 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 Inter-bank 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. On September 25, 2018, the Company extended the maturity date of Trade Receivable Facility, which contains a cross-default provision to the Company’s other debt agreements, to September 25, 2019.

On April 16, 2018, the maturity date, the Company repaid the $300,000,000 of the 6.6% Senior Notes with cash on hand.

6.	Long-Term Debt (continued)

The Company has a $700,000,000 five-year senior unsecured revolving facility (the Revolving Facility) 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. 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 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 $50,000,000, such reduction not to exceed $200,000,000, for purposes of the covenant calculation. The Company was in compliance with this Ratio at September 30, 2018.

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 $2,301,000 of outstanding letters of credit issued under the Revolving Facility at September 30, 2018 and December 31, 2017 and $1,963,000 at September 30, 2017.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. The amortization of the terminated value of the forward starting interest rate swap agreements was complete with the maturity of the related debt in April 2018. For the nine-months ended September 30, 2018, the Company recognized $458,000 as additional interest expense. For the three- and nine-months ended September 30, 2017, the Company recognized $369,000 and $1,089,000, respectively, as additional interest expense.

7.	Financial Instruments

The Company’s financial instruments include cash equivalents, accounts receivable, notes receivable, bank overdrafts, 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. However, accounts receivable are more heavily concentrated in certain states (namely, Texas, Colorado, North Carolina, Iowa and Georgia). 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.

Bank overdrafts, when applicable, represent amounts to be funded to financial institutions for checks that have cleared the bank. The estimated fair value of bank overdrafts approximates its carrying value due to the short-term nature of the overdraft.

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.

7.	Financial Instruments (continued)

The carrying values and fair values of the Company’s long-term debt were $3,209,698,000 and $3,144,615,000, respectively, at September 30, 2018; $3,027,203,000 and $3,144,902,000, respectively, at December 31, 2017; and $1,722,540,000 and $1,830,750,000, respectively, at September 30, 2017. The estimated fair value of the publicly-registered long-term notes was estimated based on Level 1 of the fair value hierarchy using quoted market prices. The estimated fair value of other borrowings, which primarily represents variable-rate debt, was based on Level 2 of the fair value hierarchy using quoted market prices for similar debt instruments, and approximates their carrying amounts as the interest rates reset periodically.

8.	Income Taxes

The Company’s effective income tax rate for the nine-months ended September 30, 2018 was 18.3%. 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. For the nine-months ended September 30, 2018, the effective income tax rate also reflects a permanent net income tax benefit of $15,454,000 resulting primarily from (i) the Company making additional contributions of $125,000,000 for a total of $150,000,000 discretionary contributions to its qualified pension plan during the quarter ended September 30, 2018, which is deductible on the Company’s 2017 income tax return; and (ii) changes in the Company’s method of accounting for income tax purposes to accelerate the deduction of various expenses. Prior to the quarter ended September 30, 2018, the Company had included an estimate of $25,000,000 of discretionary pension plan contributions in its 2017 tax provision. The tax benefit resulted from the difference in the federal tax rate at which the deductions were claimed versus the tax rate at which the deferred tax assets were recorded at year end as a result of the Tax Reform Act (2017 Tax Act), net of the correlative effects of reduced deductions for domestic production deduction and percentage depletion. The enactment of the 2017 Tax Act reduced the federal statutory corporate income tax rate from 35% to 21% beginning in 2018. Therefore, the effective income tax rate of 26.2% for the nine-months ended September 30, 2017 is not comparable.

The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (SAB 118) to address situations when a registrant does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. As such, due to the timing of the enactment date and the Company’s reporting periods, the Company recognized provisional amounts for the remeasurement of deferred tax assets and liabilities, including the tax benefit mentioned above, and transition tax on undistributed foreign earnings as of September 30, 2018. In accordance with SAB 118, the Company may record additional provisional amounts during the measurement period not to extend beyond one year of the enactment date. The Company will complete its analysis after the filing of its federal and state corporate income tax returns in the fourth quarter.

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.

In the quarter ended September 30, 2018, the Company made $150,000,000 of discretionary contributions to its qualified pension plan. No additional contributions to the qualified pension plan are expected to be made for the remainder of 2018. The Company currently estimates that it will contribute a total of $12,400,000 for the year ending December 31, 2018 to satisfy required payments under the unfunded nonqualified pension plans.

10.	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 $15,500,000 revolving line of credit agreement with BB&T with 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 $6,000,000 interest-only loan, due December 31, 2019, outstanding from this unconsolidated affiliate as of September 30, 2018, December 31, 2017 and September 30, 2017. The interest rate is one-month LIBOR plus 1.75%.

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.

11.	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 is held at Corporate.

The following table displays selected financial data for the Company’s reportable business segments. The acquired Bluegrass operations 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.

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:

RESULTS OF OPERATIONS

Third Quarter Ended September 30, 2018

(Continued)

Volume growth accelerated during the quarter’s first two months, reflecting strong underlying product demand, most notably in Texas, North Carolina, Georgia and Iowa. Despite clear market strength, extreme weather temporarily hindered construction activity. Record precipitation in Texas, compounded by disruptions from Hurricane Florence in the Carolinas, adversely impacted September’s aggregates shipment, production and overall efficiency levels.

Heritage aggregates volume and pricing improved 3.8% and 2.9%, respectively, excluding the third-quarter 2017 shipments from the Company’s Forsyth, Georgia, quarry that was divested in April 2018.

Aggregates shipments to the infrastructure market were flat as large public projects in North Carolina and Texas were weather delayed. The Company remains encouraged by the recent acceleration of state lettings and contract awards. As state Departments of Transportation (DOTs) and contractors continue to address labor constraints, and the broader industry benefits from further regulatory reform, management remains confident that infrastructure demand will continue to improve driven by funding provided by the Fixing America’s Surface Transportation Act (FAST Act) and numerous state and local transportation initiatives. While some contractors are reporting longer lag times between contract awards and project commencement, public construction projects, once awarded, are seen through to completion. Thus, delays from weather or other factors typically serve to extend the duration of the construction cycle for the Company’s single largest end-use market. Aggregates shipments to the infrastructure market comprised 41% of third-quarter aggregates volumes. On a year-to-date basis, the infrastructure market represented 39% of aggregates shipments, remaining below the Company’s most recent five-year average of 43%.

Aggregates shipments to the nonresidential market increased 5%, driven by both commercial and heavy industrial construction activity. Looking ahead, ongoing energy-sector project approvals, supported by higher oil prices, underpin management’s expectation that the next wave of these large projects, particularly along the Gulf Coast, will contribute to increased aggregates demand for the next several years. The nonresidential market represented 33% of third-quarter aggregates shipments.

Aggregates shipments to the residential market increased 7%. Florida, Texas, Colorado, North Carolina, South Carolina and Georgia, six of the Company’s key states, ranked in the top ten nationally for growth in single-family housing unit starts for the trailing twelve months ended August 2018. 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 and efficient permitting. The residential market accounted for 20% of third-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 6% of third-quarter aggregates shipments. Shipments to this sector increased 6%, reflecting improved ballast shipments from the Midwest and Rocky Mountain Divisions.

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

	Three-Months Ended
	September 30,
	2018		2017		% Change

Among other items, other operating income, 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 third quarter, consolidated other operating expense, net, was $3.8 million in 2018 and $6.2 million in 2017. The 2018 amount reflects $7.1 million in restructuring expenses related to the Company’s Southwest ready mixed concrete operations. The 2017 amount includes a $12.4 million expense for repair costs related to certain of the Company’s leased railcars.

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 third quarter, other nonoperating income, net, was $4.2 million and $0.5 million in 2018 and 2017, respectively. The increase in 2018 compared with 2017 primarily reflects higher earnings from nonconsolidated equity investments.

Consolidated Operating Results

For the nine-months ended September 30, 2018 and 2017, consolidated SG&A was 6.5% of total revenues. Earnings from operations for the first nine months were $543.7 million in 2018 compared with $517.0 million in 2017.

For the nine-months ended September 30, consolidated other operating income, net, was $27.0 million in 2018 and $2.6 million in 2017. The increase in other operating income, net, is primarily driven by a $16.9 million gain on the sale of surplus land and a $7.7 million net gain on litigation and related settlements of in 2018 partially offset by $7.1 million in restructuring expenses related to the Company’s Southwest ready mixed concrete operations. The 2017 amount includes a $13.5 million gain on the sale of real estate offset by a $12.4 million expense for repair costs related to certain of the Company’s lease railcars and $6.1 million of expense, including both cash and stock-based compensation components, related to the retirement of a senior executive officer.

For the nine-months ended September 30, 2018, other nonoperating income, net, was $19.9 million, a $13.4 million increase compared with prior year, reflecting higher interest income and lower pension expense.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the nine-months ended September 30 was $441.5 million in 2018 compared with $418.1 million in 2017. Operating cash flow is primarily derived from consolidated net earnings before deducting depreciation, depletion and amortization, and the impact of changes in working capital. Depreciation, depletion and amortization were as follows:

	Nine-Months Ended
	September 30,
	2018		2017
	(Dollars in Thousands)
Depreciation	$	219,019	$	195,009
Depletion		20,576		12,812
Amortization		13,605		13,597
	$	253,200	$	221,418

The seasonal nature of construction activity impacts the Company’s quarterly operating cash flow when compared with the full year. Full-year 2017 net cash provided by operating activities was $657.6 million, reflective of the reclassification of net proceeds and payments of corporate-owned life insurance of $0.3 million from operating activities to investing activities, compared with $418.1 million for the first nine months of 2017.

During the nine-months ended September 30, 2018, the Company paid $262.2 million for capital investments. Full-year capital spending is expected to approximate $375 million.

The Company can repurchase its common stock through open-market purchases pursuant to authority granted by its Board of Directors or through private transactions at such prices and upon such terms as the Chief Executive Officer deems appropriate. The Company repurchased 305,000 shares of common stock during the first nine months of the year for an aggregate purchase price of $60.4 million. At September 30, 2018, 14,364,000 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

(Continued)

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 September 30, 2018, the Company’s ratio of consolidated debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, for the trailing-twelve months was 2.72 times and was calculated as follows:

	October 1, 2017 to
	September 30, 2018
	(Dollars in thousands)
Earnings from continuing operations attributable to Martin Marietta	$	752,804
Add back:
Interest expense		126,976
Depreciation, depletion and amortization expense		325,410
Stock-based compensation expense		29,846
Acquisition-related expenses, net		51,441
Noncash portion of restructuring expenses		5,245
Bluegrass EBITDA - Pre-acquisition adjusted (October 2017 to April 2018)		43,417
Deduct:
Interest income		(7,149	)
Income tax benefit		(129,691	)
Gain on divestiture		(14,785	)
Consolidated EBITDA, as defined by the Company’s Revolving Facility	$	1,183,514
Consolidated net debt, as defined and including debt for which the Company is a co-borrower, at September 30, 2018	$	3,224,046
Consolidated debt-to-consolidated EBITDA, as defined by the Company’s Revolving Facility, at September 30, 2018 for the trailing-twelve months EBITDA	2.72x

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. On April 27, 2018, the Company successfully completed its acquisition of Bluegrass Materials Company (Bluegrass), the largest privately-held, pure-play aggregates company in the United States, for $1.617 billion in cash. The Company financed the Bluegrass acquisition using proceeds from issuances of senior notes in December 2017 and borrowings under credit facilities. 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 September 30, 2018, the Company had $617.7 million of unused borrowing capacity under its Revolving Facility and Trade Receivable Facility, subject to complying with the related leverage covenant. The Revolving Facility expires on December 5, 2021. On April 17, 2018, the Company and its wholly-owned subsidiary amended its Trade Receivable Facility to increase the facility limit to $400 million. On September 25, 2018, the Company extended the maturity of the Trade Receivable Facility to September 25, 2019.

The Company repaid the $300 million of 6.60% Senior Notes with cash on hand on April 16, 2018, the maturity date.

On May 22, 2017, the Company issued $300 million aggregate principal amount of Floating Rate Senior Notes due in 2020 and $300 million aggregate principal amount of 3.450% Senior Notes due in 2027. On December 20, 2017, the Company issued $300 million aggregate principal amount of Floating Rate Senior Notes due 2019, $500 million aggregate principal amount of 3.500% Senior Notes due 2027 and $600 million aggregate principal amount of 4.250% Senior Notes due 2047. The Company repaid $300 million aggregate principal amount of Floating Rate Senior at its maturity in June 2017.

The Company is exposed to the credit markets, through the interest cost related to its variable-rate debt, which included borrowings under its Revolving Facility and Trade Receivable Facility and the obligations in respect of the Floating Rate Notes. The Company is currently rated at an investment-grade level by all three credit rating agencies.

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, 2017. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK

Management has updated its full-year 2018 guidance to reflect current trends and expectations, including the impact of extraordinary weather-related events encountered during the third quarter.

Specifically:

♦

Heritage aggregates average selling price is expected to increase in a range of 3% to 4%.

♦

Heritage aggregates volume is expected to be flat to up to 1% and expected shipments by end-use market, both compared with 2017 levels and excluding 2017 shipments of the Company’s Forsyth, Georgia, quarry that was divested in April 2018, are as follows:

•

Infrastructure shipments to be relatively flat.

•

Nonresidential shipments to increase in the low- to mid-single digits.

•

Residential shipments to increase in the high-single digits.

•

ChemRock/Rail shipments to decrease.

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 has raised rates three times during 2018, increasing the federal funds rate to 2.2%. The residential construction market accounted for 21% of the Company’s aggregates product line shipments in 2017.

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 September 30, 2018, 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 $1.08 billion, which was the collective outstanding balance at September 30, 2018, would increase interest expense by $10.8 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, 2017.

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 2018 coal requirements. Energy costs for the nine-months ended September 30, 2018 increased approximately 13% over the prior-year period. A hypothetical 15% change in the Company’s energy prices for the full year 2018 as compared with 2017, assuming constant volumes, would change full year 2018 energy expense by $37.4 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 2018 of $415 million to $445 million, a hypothetical 10% change in sales price would impact net sales by $41.5 million to $44.5 million.

EXHIBIT 95

MINE SAFETY DISCLOSURES

The operation of the Corporation’s domestic aggregates quarries and mines is subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects the Corporation’s quarries and mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders may be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act), the Corporation is required to present information regarding certain mining safety and health citations which MSHA has issued with respect to its aggregates mining operations in its periodic reports filed with the Securities and Exchange Commission (SEC). In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the quarry or mine and types of operations (underground or surface), (ii) the number of citations issued will vary from inspector to inspector and location to location, and (iii) citations and orders can be contested and appealed, and in that process, may be reduced in severity and amount, and are sometimes dismissed.

The Corporation has provided the information below in response to the SEC’s rules and regulations issued under the provisions of the Dodd-Frank Act. The disclosures reflect U.S. mining operations only, as the requirements of the Dodd-Frank Act and the SEC rules and regulations thereunder do not apply to the Corporation’s quarries and mines operated outside the United States.

The Corporation presents the following items regarding certain mining safety and health matters for the three months ended September 30, 2018:

•

Total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under section 104 of the Mine Act for which the Corporation has received a citation from MSHA (hereinafter, “Section 104 S&S Citations”). If MSHA determines that a violation of a mandatory health or safety standard is likely to result in a reasonably serious injury or illness under the unique circumstance contributed to by the violation, MSHA will classify the violation as a “significant and substantial” violation (commonly referred to as an S&S violation). MSHA inspectors will classify each citation or order written as an S&S violation or not.

•

Total number of orders issued under section 104(b) of the Mine Act (hereinafter, “Section 104(b) Orders”). These orders are issued for situations in which MSHA determines a previous violation covered by a Section 104(a) citation has not been totally abated within the prescribed time period, so a further order is needed to require the mine operator to immediately withdraw all persons (except authorized persons) from the affected area of a quarry or mine.

•	Total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under Section 104(d) of the Mine Act (hereinafter, “Section 104(d) Citations and Orders”). These violations are similar to those described above, but the

standard is that the violation could significantly and substantially contribute to the cause and effect of a safety or health hazard, but the conditions do not cause imminent danger, and the MSHA inspector finds that the violation is caused by an unwarranted failure of the operator to comply with the health and safety standards.

•

Total number of flagrant violations under section 110(b)(2) of the Mine Act (hereinafter, “Section 110(b)(2) Violations”). These violations are penalty violations issued if MSHA determines that violations are “flagrant”, for which civil penalties may be assessed. A “flagrant” violation means a reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury.

•

Total number of imminent danger orders issued under section 107(a) of the Mine Act (hereinafter, “Section 107(a) Orders”). These orders are issued for situations in which MSHA determines an imminent danger exists in the quarry or mine and results in orders of immediate withdrawal of all persons (except certain authorized persons) from the area of the quarry or mine affected by its condition until the imminent danger and the underlying conditions causing the imminent danger no longer exist.

•

Total dollar value of proposed assessments from MSHA under the Mine Act. These are the amounts of proposed assessments issued by MSHA with each citation or order for the time period covered by the reports. Penalties are assessed by MSHA according to a formula that considers a number of factors, including the mine operator’s history, size, negligence, gravity of the violation, good faith in trying to correct the violation promptly, and the effect of the penalty on the operator’s ability to continue in business.

•

Total number of mining-related fatalities. Mines subject to the Mine Act are required to report all fatalities occurring at their facilities unless the fatality is determined to be “non-chargeable” to the mining industry. The final rules of the SEC require disclosure of mining-related fatalities at mines subject to the Mine Act. Only fatalities determined by MSHA not to be mining-related may be excluded.

•

Receipt of written notice from MSHA of a pattern (or a potential to have such a pattern) of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of other mine health or safety hazards under Section 104(e) of the Mine Act. If MSHA determines that a mine has a “pattern” of these types of violations, or the potential to have such a pattern, MSHA is required to notify the mine operator of the existence of such a thing.

•	Legal actions before the Federal Mine Safety and Health Review Commissions pending as of the last day of period.

•	Legal actions before the Federal Mine Safety and Health Review Commissions initiated during period.

•	Legal actions before the Federal Mine Safety and Health Review Commissions resolved during period.

The Federal Mine Safety and Health Review Commission (the Commission) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. The cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under Section 105 of the Mine Act. Appendix 1 shows, for each of the Corporation’s quarries and mines identified, as of September 30, 2018, the number of legal actions pending before the Commission, along with the number of legal actions initiated before the Commission during the quarter as well as resolved during the quarter. In addition, Appendix 1 includes a footnote to the column for legal actions before the Commission pending as of the last day of the period, which footnote breaks down that total number of legal actions pending by categories according to the type of proceeding in accordance with various categories established by the Procedural Rules of the Commission.
