Organization

Martin Marietta Materials, Inc. (the Corporation or Martin Marietta) is engaged principally in the building materials business, including aggregates, cement, ready mixed concrete and asphalt and paving product lines, collectively reported as the Building Materials business. The aggregates product line is sold and shipped from a network of more than 270 quarries and distribution facilities in 26 states, Nova Scotia and the Bahamas. The cement, ready mixed concrete and asphalt and paving product lines are located in strategic, vertically integrated markets, predominately Texas and Colorado. Building materials are used for construction of highways and other infrastructure projects, and in the nonresidential and residential construction industries. Aggregates and cement products are also used in the railroad, agricultural, utility and environmental industries.

Effective January 1, 2017, the Corporation reorganized the operations and management reporting structure of its Texas-based aggregates, cement and ready mixed concrete product lines, resulting in a change to its reportable segments. As a result, the cement product line is reported in the West Group. The Corporation’s Building Materials business includes three reportable segments: the Mid-America Group, the Southeast Group and the West Group.

Basis of Presentation

The accompanying unaudited consolidated financial statements of the Corporation have been prepared in accordance with generally accepted accounting principles 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 adoption of two new accounting standards described below, the Corporation has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2016. 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, 2017 are not indicative of the results expected for other interim periods or the full year. The consolidated balance sheet at December 31, 2016 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by generally accepted accounting principles 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 Corporation’s Annual Report on Form 10-K for the year ended December 31, 2016.

New Accounting Pronouncements

Share-Based Payment Accounting

Effective January 1, 2017, the Corporation adopted Accounting Standards Update (ASU) 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), which simplifies certain aspects of accounting guidance and requirements for share-based transactions. ASU 2016-09 requires shares withheld for employees’ income tax obligations to be presented as a financing activity in the Statement of Cash Flows, with retrospective presentation. For the quarter ended March 31, 2016, the Corporation reclassified $26,000 from operating activities to financing activities on the Statement of Cash Flows. Additionally, excess tax benefits from stock-based compensation transactions are presented as an operating activity with retrospective presentation. The Corporation previously presented excess tax benefits from stock-based compensation transactions as a financing activity and, for the quarter ended March 31, 2016, reclassified $1,278,000 to operating activities on the Statement of Cash Flows. ASU 2016-09 also requires excess tax benefits and tax deficiencies to be recognized prospectively as income tax benefits or expense in the period awards vest or are exercised. For the three months ended March 31, 2017, the Corporation recognized excess tax benefits of $2,270,000.

New Accounting Pronouncements

Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

In March 2017, the Financial Accounting Standards Board (FASB) issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07), which revises the accounting for periodic pension and postretirement expense. ASU 2017-07 requires net periodic benefit cost, with the exception of service cost, to be presented retrospectively as nonoperating expense. As permitted by ASU 2017-07, the Corporation used the pension and other postretirement benefit plan disclosures for the prior comparative periods as a practical expedient to estimate amounts for retrospective application. Service cost will remain a component of earnings from operations and represent the only cost of pension and postretirement expense eligible for capitalization, notably in the Corporation’s inventory standards. The Corporation early adopted this standard effective January 1, 2017. For the three months ended March 31, 2016, the Corporation reclassified $616,000, $1,512,000 and $126,000 from cost of sales; selling, general and administrative costs; and other operating income and expenses, respectively, to nonoperating expense.

Pending Accounting Pronouncements

Revenue Recognition Standard

The FASB issued an accounting standards update that amends the accounting guidance on revenue recognition. The new standard intends to provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices and improve disclosure requirements. The new standard is effective January 1, 2018 and can be applied on a full retrospective or modified retrospective approach. The Corporation has completed its initial assessment of the provisions of the new standard and, at this time, does not expect the impact to be material to its results of operations.

Lease Standard

In February 2016, the FASB issued a new accounting standard, Accounting Codification Standard 842 – Leases, 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 on the balance sheet and provides guidance on the recognition of lease expense and income. The new standard is effective January 1, 2019 and must be applied on a modified retrospective approach. The Corporation is currently assessing the impact of the updated standard on the Corporation’s financial statements. The Corporation believes the updated standard will have a material effect on its balance sheet but has not quantified the impact at this time.

Reclassifications

Prior-year information has been reclassified to conform to the presentation of the Corporation’s current reportable segments and for the adoption of the two accounting pronouncements aforementioned.

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 Corporation’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 Corporation’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive. For the three months ended March 31, 2017 and 2016, the diluted per-share computations reflect a change in 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:

4.	Long-Term Debt (continued)

The Corporation, through a wholly-owned special-purpose subsidiary, has a $300,000,000 trade receivable securitization facility (the Trade Receivable Facility), which matures on September 27, 2017. 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 $362,693,000, $333,302,000 and $327,734,000 at March 31, 2017, December 31, 2016 and March 31, 2016, respectively. These receivables are originated by the Corporation and then sold to the wholly-owned special-purpose subsidiary by the Corporation. The Corporation 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 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 contains a cross-default provision to the Corporation’s other debt agreements.

The Corporation has a credit agreement 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 Credit Agreement), which provides a $700,000,000 five-year senior unsecured revolving facility (the Revolving Facility). The Credit Agreement requires the Corporation’s ratio of consolidated debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined by the Credit Agreement, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Corporation 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 Corporation is a co-borrower, may be reduced by the Corporation’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 Corporation was in compliance with this Ratio at March 31, 2017.

Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Corporation under the Revolving Facility. At March 31, 2017, December 31, 2016 and March 31, 2016, the Corporation had $2,507,000 of outstanding letters of credit issued under the Revolving Facility.

Current maturities of long-term debt and short-term facilities consist of borrowings under the Trade Receivable Facility as well as the current portions of the other notes.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three months ended March 31, 2017 and 2016, the Corporation recognized $356,000 and $332,000, respectively, as additional interest expense. The ongoing amortization of the terminated value of the forward starting interest rate swap agreements will increase annual interest expense by approximately $1,400,000 until the maturity of the 6.6% Senior Notes in 2018.

5.	Financial Instruments

The Corporation’s financial instruments include cash equivalents, accounts receivable, notes receivable, bank overdraft, 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 Corporation’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.

The bank overdraft represents amounts to be funded to financial institutions for checks that have cleared the bank. The estimated fair value of the bank overdraft 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.

The carrying values and fair values of the Corporation’s long-term debt were $1,846,294,000 and $1,937,310,000, respectively, at March 31, 2017; $1,686,189,000 and $1,752,338,000, respectively, at December 31, 2016; and $1,752,757,000 and $1,817,950,000, respectively, at March 31, 2016. 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.

6.	Income Taxes

The Corporation’s effective income tax rate for the three months ended March 31, 2017 was 25.6%. The effective income tax rate reflects the effect of federal and state income taxes and the impact of differences in book and tax accounting arising from the net permanent benefits associated with the statutory depletion deduction for mineral reserves and the domestic production deduction. For the three months ended March 31, 2017, as a result of the adoption of ASU 2016-09 (see Note 1), the effective income tax rate reflects the excess tax benefit related to the vesting and exercise of stock-based compensation awards, which are treated as discrete events. As previously stated in Note 1, this requirement of the ASU is prospective and therefore, prior year results are not comparable.

The Corporation 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.

8.	Commitments and Contingencies

Legal and Administrative Proceedings

The Corporation 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 Corporation and its subsidiaries, will have a material adverse effect on the overall results of the Corporation’s operations, its cash flows or its financial position.

Borrowing Arrangements with Affiliate

The Corporation is a co-borrower with an unconsolidated affiliate for a $25,000,000 revolving line of credit agreement with BB&T Bank. The affiliate has agreed to reimburse and indemnify the Corporation for any payments and expenses the Corporation may incur from this agreement. The Corporation 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 Corporation has a $6,000,000 interest-only loan, due December 31, 2019, outstanding from this unconsolidated affiliate as of March 31, 2017, December 31, 2016 and March 31, 2016. The interest rate is one-month LIBOR plus 1.75%.

Employees

Approximately 10% of the Corporation’s employees are represented by a labor union. All such employees are hourly employees. The Corporation maintains collective bargaining agreements relating to the union employees with the Aggregates business and Magnesia Specialties segments. For the Magnesia Specialties segment located in Manistee, Michigan and Woodville, Ohio, 100% of its hourly employees are represented by labor unions. The Manistee collective bargaining agreement expires in August 2019, and the Woodville collective bargaining agreement expires in May 2018.

9.	Business Segments

The Building Materials business contains three reportable business segments: Mid-America Group, Southeast Group and West Group. The Corporation also has a Magnesia Specialties segment. The Corporation’s evaluation of performance and allocation of resources are based primarily on earnings from operations. Consolidated earnings from operations include net sales less cost of sales, 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 consolidated loss from operations primarily includes depreciation on capitalized interest, expenses for corporate administrative functions, acquisition-related expenses, net, and other nonrecurring and/or non-operational income and expenses excluded from the Corporation’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 continuing operations for the Corporation’s reportable business segments. Total revenues and net sales in the table below, as well as the consolidated statements of earnings and comprehensive earnings, exclude intersegment sales which represent net sales from one segment to another segment which are eliminated.

11.	Business Combinations

In the first quarter 2016, the Corporation acquired the outstanding stock of Rocky Mountain Materials and Asphalt, Inc., and Rocky Mountain Premix Inc. The acquisition provides more than 500 million tons of mineral reserves and expands the Corporation’s presence along the Front Range of the Rocky Mountains, home to 80% of Colorado’s population. The acquired operations are reported through the West Group.

In July 2016, the Corporation acquired the remaining interest in Ratliff Ready-Mix, L.P. (“Ratliff”), which operates ready mixed concrete plants in central Texas. Prior to the acquisition, the Corporation owned a 40% interest in Ratliff which was accounted for under the equity method. The Corporation was required to re-measure the existing 40% interest to fair value upon closing of the transaction, resulting in a gain of $5,863,000, which was recorded in other nonoperating income in third quarter 2016. These operations are reported in the West Group. The Corporation recorded preliminary fair values of the assets acquired and liabilities assumed; however, deferred income taxes and goodwill are subject to change upon review of the seller’s final tax return.

The impact of these acquisitions on the operating results was not considered material; therefore, pro forma financial information is not included.

RESULTS OF OPERATIONS

First Quarter Ended March 31, 2017

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

OVERVIEW

Martin Marietta Materials, Inc. (the Corporation or Martin Marietta) is a leading supplier of building materials, including aggregates, cement, ready mixed concrete and asphalt and paving (collectively herein referred to as the Building Materials business). The aggregates product line is sold and shipped from a network of more than 270 quarries and distribution facilities in 26 states, Nova Scotia and the Bahamas. The cement, ready mixed concrete and asphalt and paving product lines are located in strategic, vertically-integrated markets, predominately Texas and Colorado. The Corporation’s annual consolidated net sales and earnings from operations are predominately derived from its Building Materials business which sells to all sectors of the public infrastructure, environmental industries, nonresidential and residential construction industries, as well as agriculture, railroad ballast, chemical, utility and other uses. The Building Materials business’ products are used primarily by commercial customers principally in domestic construction of highways and other infrastructure projects and for nonresidential and residential building development.

Effective January 1, 2017, the Corporation reorganized the operations and management reporting structure of its Texas-based aggregates, ready mixed concrete and cement product lines, resulting in a change to its reportable segments. The Corporation currently conducts its Building Materials business through three reportable business segments: Mid-America Group, Southeast Group and West Group.

BUILDING MATERIALS BUSINESS
Reportable Segments	Mid-America Group	Southeast Group	West Group
Operating Locations	Indiana, Iowa, northern Kansas, Kentucky, Maryland, Minnesota, Missouri, eastern Nebraska, North Carolina, Ohio, South Carolina, Virginia, Washington and West Virginia	Alabama, Florida, Georgia, Tennessee, Nova Scotia and the Bahamas	Arkansas, Colorado, southern Kansas, Louisiana, western Nebraska, Nevada, Oklahoma, Texas, Utah and Wyoming

Product Lines	Aggregates (crushed stone, sand and gravel)	Aggregates (crushed stone, sand and gravel)	Aggregates (crushed stone, sand and gravel), cement (Portland and specialty cements), ready mixed concrete and asphalt and paving

Plant Types	Quarries and Distribution Facilities	Quarries and Distribution Facilities	Quarries, Plants and Distribution Facilities

Modes of Transportation	Truck and Rail	Truck, Rail and Water	Truck and Rail

The Corporation also has a Magnesia Specialties segment that produces magnesia-based chemicals products used in industrial, agricultural and environmental applications and dolomitic lime sold primarily to customers in the steel industry.

RESULTS OF OPERATIONS

First Quarter Ended March 31, 2017

(Continued)

CRITICAL ACCOUNTING POLICIES

The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2016. There were no changes to the Corporation’s critical accounting policies during the three months ended March 31, 2017.

RESULTS OF OPERATIONS

Except as indicated, the comparative analysis in this Management’s Discussion and Analysis of Financial Condition and Results of Operations is based on net sales and cost of sales. Gross margin and operating margin calculated as percentages of total revenues represent the most directly comparable financial measures calculated in accordance with generally accepted accounting principles (GAAP). However, gross margin as a percentage of net sales and operating margin as a percentage of net sales represent non-GAAP measures. The Corporation presents these ratios calculated based on net sales, as it is consistent with the basis by which management reviews the Corporation’s operating results. Further, management believes it is consistent with the basis by which investors analyze the Corporation’s operating results given that freight and delivery revenues and costs represent pass-throughs and have no profit mark-up. The following tables present the calculations of gross margin and operating margin for the three months ended March 31, 2017 and 2016 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales.

Earnings before interest, income taxes, depreciation, depletion 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 Corporation’s management believes that EBITDA may provide additional information with respect to the Corporation’s performance or ability to meet its future debt service, capital expenditures or working capital requirements. Because EBITDA exclude some, but not all, items that affect net earnings and may vary among companies, the EBITDA presented by the Corporation 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:

For the quarter, shipments to the infrastructure market comprised 37% of aggregates product line volumes. The percentage of shipments going into the infrastructure market remains below the Corporation’s five-year average, attributable to continued under-investment in the nation’s infrastructure and greater private sector nonresidential and residential investments. Also, infrastructure construction activity saw little first-quarter benefit from the Fixing America’s Surface Transportation, or FAST Act. Management expects increased federal, state and local infrastructure activity as the year progresses and the construction season begins in earnest.

The nonresidential market represented 32% of first-quarter aggregates product line shipments. The light nonresidential market, which consists primarily of office and retail construction, increased for the quarter; however, lower heavy nonresidential activity, which includes industrial building as well as energy and energy-related construction, was lower, resulting in a 5.0% decrease in overall nonresidential shipments. In-line with management’s expectations, the decline in heavy nonresidential was primarily due to the completion in 2016 of several large energy-related projects in the West Group that were not immediately replaced in the first quarter 2017 and also a more typical start to the Mid-America Group’s construction season.

(Continued)

The residential market accounted for 22% of aggregates product line shipments for the first quarter. Volumes to this segment increased 27%, driven by continued strength in housing across the Corporation’s geographic footprint. Florida, Texas, North Carolina and Georgia, key geographies for the Building Materials business, comprised the top four states for single family housing starts as of February 2017. Additionally, on the metro-level, Austin, Atlanta, Charlotte, Dallas, Orlando, Tampa and Raleigh comprised the top seven for single family unit starts, with all but Dallas experiencing double-digit growth.

The ChemRock/Rail market accounted for the remaining 9% of aggregates product line volumes. The volume decline in this market principally reflects reduced ballast shipments.

Aggregates product line shipments were relatively flat compared with a record-breaking first quarter 2016; however, the Southeast Group’s volume increased 16.4%. The Mid-America and West Groups shipment decreases of 1.5% and 3.8%, respectively, are relatively modest against a very strong early 2016. Including shipments from acquired businesses, ready mixed concrete shipments increased 15%. Total cement shipments decreased 5.4%, again, versus a challenging prior year comparison. The cement product line has backlog of approximately $98 million and $90 million as of March 31, 2017 and December 31, 2016, respectively.

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

	Three Months Ended
	March 31,
	2017		2016		% Change
Aggregates (per ton)	$	13.73	$	13.04		5.3	%
Cement (per ton)	$	102.54	$	100.04		2.5	%
Ready Mixed Concrete (per cubic yard)	$	105.84	$	102.45		3.3	%
Asphalt (per ton)	$	37.97	$	42.62		(10.9	)%

Solid pricing growth across the product lines and geographies reinforces management’s view of the healthy, underlying demand fundamentals that underpin the Building Materials business. Aggregates pricing gains of 5.3% led all product lines in the first quarter. The cement product line reported renewed pricing growth in advance of the announced $8.00 per ton price increase effective April 1, 2017.

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 occurs 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 shipments, production and profitability in all markets served by the Corporation. Because of the potentially significant impact of weather on the Corporation’s operations, current period and year to date results are not indicative of expected performance for other interim periods or the full year.

Magnesia Specialties Business

Magnesia Specialties reported first-quarter net sales of $63.3 million compared with $59.5 million, reflecting growth in both the chemicals and lime product lines. Gross profit for the first quarter was $22.3 million compared to $23.0 million and earnings from operations were $19.9 million compared to $20.6 million. Production costs outpaced net sales increases due to higher natural gas prices and planned and unplanned maintenance costs at the Woodville and Manistee plants.

The consolidated gross margin (excluding freight and delivery revenues) for the quarter was 18.6%, a 120-basis-point decline compared with the prior-year quarter. Gross margin (excluding freight and delivery revenues) for the Building Materials business was 17.2%, reflecting a greater share of total sales in the quarter from both the Corporation’s long-haul and vertically-integrated markets. The reduction in gross margin of 150 basis points also reflects the investment made in preparation for the higher demand expected through the balance of the year, the fixed cost nature of the business during a seasonally lower volume quarter and carefully executed inventory management plans. Cement kiln maintenance costs were $4.2 million for the quarter compared with $5.6 million.

Consolidated Operating Results

Consolidated SG&A was 8.8% of net sales compared with 7.9% in the prior-year quarter. The increase of 90 basis points reflects a higher first-quarter accrual rate related to incentive compensation costs compared with the prior-year quarter. Earnings from operations for the quarter were $77.2 million compared with $86.0 million in the prior-year quarter.

Among other items, other operating income and 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 and expenses, net, was an expense of $0.4 million and $0.6 million in 2017 and 2016, respectively.

Other nonoperating income and expenses, net, includes pension and postretirement benefit cost, excluding service cost; foreign currency transaction gains and losses; interest; equity adjustments for nonconsolidated affiliates and other miscellaneous income. For the first quarter, nonoperating income and expenses, net, was income of $0.5 million in 2017 and expense of $1.2 million in 2016. The increase is attributable to higher income earned from nonconsolidated affiliates.

The estimated effective income tax rate for the quarter was 25.6%, which, as a result of the adoption of ASU 2016-09 (see Note 1), reflects a 400 basis point favorable impact from excess tax benefits related to stock-based compensation, which are treated as discrete events effective January 1, 2017.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the three months ended March 31, 2017 was $74.0 million compared with $68.3 million for the same period in 2016. 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:

The seasonal nature of the aggregates-led construction business impacts quarterly operating cash flow when compared with the full year. Full-year 2016 net cash provided by operating activities was $689.2 million compared with $68.3 million for the first three months of 2016.

During the three months ended March 31, 2017, the Corporation had capital spending of $102.1 million. Full-year capital spending is expected to approximate $400 million - $500 million.

The Corporation 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. During the first quarter, the Corporation repurchased 458,000 shares of common stock for $100 million. At March 31, 2017, 14,669,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Credit Agreement (which consists of a $700 million Revolving Facility) requires the Corporation’s ratio of consolidated debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization (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 Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions during the quarter or the three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if there are no amounts outstanding under the Revolving Facility and the Trade Receivable Facility, consolidated debt, including debt for which the Corporation is a co-borrower, may be reduced by the Corporation’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 Corporation is a co-borrower, divided by consolidated EBITDA, as defined by the Corporation’s Credit Agreement, for the trailing-twelve months. Consolidated EBITDA is generally defined as earnings before interest expense, income tax expense, and depreciation, depletion 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. Certain other nonrecurring noncash items, if they occur, can affect the calculation of consolidated EBITDA.

At March 31, 2017, the Corporation’s ratio of consolidated debt-to-consolidated EBITDA, as defined by the Corporation’s Credit Agreement, for the trailing-twelve months EBITDA was 1.89 times and was calculated as follows:

	April 1, 2016 to
	March 31, 2017
	(Dollars in thousands)
Earnings from continuing operations attributable to Martin Marietta	$	422,725
Add back:
Interest expense		82,493
Income tax expense		176,379
Depreciation, depletion and amortization expense		284,917
Stock-based compensation expense		23,528
Deduct:
Interest income		(215	)
Nonrecurring gains		(5,225	)
Consolidated EBITDA, as defined by the Corporation’s Credit Agreement	$	984,602
Consolidated net debt, as defined and including debt for which the Corporation is a co-borrower, at March 31, 2017	$	1,862,886
Consolidated debt-to-consolidated EBITDA, as defined by the Corporation’s Credit Agreement, at March 31, 2017 for the trailing-twelve months EBITDA	1.89x

The Trade Receivable Facility contains a cross-default provision to the Corporation’s other debt agreements. In the event of a default on the Ratio, the lenders can terminate the Credit Agreement 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 Corporation’s consolidated balance sheet.

Cash on hand, along with the Corporation’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, meet capital expenditures and discretionary investment needs, fund certain acquisition opportunities that may arise and allow for payment of dividends for the foreseeable future. At March 31, 2017, the Corporation had $497.5 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 November 29, 2018 and the Trade Receivable Facility expires on September 27, 2017.

The Floating Rate Notes have been classified as noncurrent liability as the Corporation has the intent and ability to refinance on a long-term basis before or at its maturity on June 30, 2017.

The Corporation may be required to obtain financing to fund certain strategic acquisitions, if any such opportunities arise, or to refinance outstanding debt. Any strategic acquisition of size for cash would likely require an appropriate balance of newly-issued equity with debt in order to maintain a composite investment-grade credit rating. Furthermore,

(Continued)

the Corporation 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 at March 31, 2017. The Corporation is currently rated at an investment-grade level by all three credit rating agencies.

TRENDS AND RISKS

The Corporation outlined the risks associated with its business in its Annual Report on Form 10-K for the year ended December 31, 2016. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK

The Corporation is encouraged by positive trends in the markets it serves and its ability to execute its strategic business plans. Notably:

•

Public sector growth is expected to continue in 2017 as new monies flow into the system. FAST Act projects should accelerate through the year, supported by ongoing activity funded through Transportation Infrastructure Finance and Innovation Act. Additionally, state and local initiatives increasing infrastructure funding, including the state and local ballot initiatives passed over the past 24 months, are expected to grow and continue to play an expanded role in public-sector activity.

•

Nonresidential construction is expected to modestly increase in both the heavy industrial and commercial sectors. The Dodge Momentum Index is at its highest level since 2009, signaling continued growth. Additional energy-related economic activity, including follow-on public and private construction activity, will be mixed. While $47 billion of new energy-related projects are scheduled to start in 2017 and 2018, the certainty and timing of commencement will affect nonresidential growth.

•

Residential construction is expected to continue to experience growth, particularly in key Martin Marietta markets, driven by employment gains, historically low levels of construction activity over the previous several years, low mortgage rates, new lot construction and higher multi-family rental rates.

OTHER MATTERS

connection with future events or future operating or financial performance. Any or all of management’s forward-looking statements here and in other publications may turn out to be wrong.

Factors that the Corporation currently believes could cause actual results to differ materially from the forward-looking statements in this Form 10-Q include, but are not limited to, the performance of the United States economy and the resolution and impact of the debt ceiling and sequestration issues; widespread decline in aggregates pricing; the history of both cement and ready mixed concrete being subject to significant changes in supply, demand and price; the termination, capping and/or reduction or suspension of the federal and/or state gasoline tax(es) or other revenue related to infrastructure construction; the level and timing of federal and state transportation funding, most particularly in Texas, North Carolina, Iowa, Colorado and Georgia; the ability of states and/or other entities to finance approved projects either with tax revenues or alternative financing structures; levels of construction spending in the markets the Corporation serves; a reduction in defense spending, and the subsequent impact on construction activity on or near military bases; a decline in the commercial component of the nonresidential construction market, notably office and retail space; a further slowdown in energy-related drilling activity, particularly in Texas; a slowdown in residential construction recovery; a reduction in construction activity and related shipments due to a decline in funding under the domestic farm bill; unfavorable weather conditions, particularly Atlantic Ocean hurricane activity, the late start to spring or the early onset of winter and the impact of a drought or excessive rainfall in the markets served by the Corporation; the volatility of fuel costs, particularly diesel fuel, and the impact on the cost of other consumables, namely steel, explosives, tires and conveyor belts, and with respect to the Magnesia Specialties business, natural gas; continued increases in the cost of other repair and supply parts; unexpected equipment failures, unscheduled maintenance, industrial accident or other prolonged and/or significant disruption to cement production facilities; increasing governmental regulation, including environmental laws; transportation availability, notably the availability of railcars and locomotive power to move trains to supply the Corporation’s Texas, Florida, North Carolina and Gulf Coast markets; increased transportation costs, including increases from higher passed-through energy and other costs to comply with tightening regulations as well as higher volumes of rail and water shipments; availability of trucks and licensed drivers for transport of the Corporation’s materials, particularly in areas with significant energy-related activity, such as Texas and Colorado; availability and cost of construction equipment in the United States; weakening in the steel industry markets served by the Corporation’s dolomitic lime products; proper functioning of information technology and automated operating systems to manage or support operations; inflation and its effect on both production and interest costs; ability to successfully integrate acquisitions quickly and in a cost-effective manner and achieve anticipated profitability to maintain compliance with the Corporation’s leverage ratio debt covenant; changes in tax laws, the interpretation of such laws and/or administrative practices that would increase the Corporation’s tax rate; violation of the Corporation’s debt covenant if price and/or volumes return to previous levels of instability; downward pressure on the Corporation’s common stock price and its impact on goodwill impairment evaluations; reduction of the Corporation’s credit rating to non-investment grade resulting from strategic acquisitions; and other risk factors listed from time to time found in the Corporation’s filings with the SEC. Other factors besides those listed here may also adversely affect the Corporation, and may be material to the Corporation. The Corporation assumes no obligation to update any such forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The Corporation’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 Corporation’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 kept the federal funds rate at or under one percent during the three months ended March 31, 2017. The residential construction market accounted for 21% of the Corporation’s aggregates product line shipments in 2016.

Aside from these inherent risks from within its operations, the Corporation’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 Corporation’s profitability increased during periods of rising interest rates. In essence, the Corporation’s underlying business generally serves as a natural hedge to rising interest rates.

Variable-Rate Borrowing Facilities. At March 31, 2017, the Corporation had a $700 million Credit Agreement and a $300 million Trade Receivable Facility. The Corporation also has $300 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 $800.0 million, which was the collective outstanding balance at March 31, 2017, would increase interest expense by $8.0 million on an annual basis.

Pension Expense. The Corporation’s results of operations are affected by its pension expense. Assumptions that affect pension expense include the discount rate and, for the defined benefit pension plans only, the expected long-term rate of return on assets. Therefore, the Corporation has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Corporation’s annual pension expense is discussed in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2016.

Energy Costs. Energy costs, including diesel fuel, natural gas, coal and liquid asphalt, represent significant production costs of the Corporation. The cement operations and Magnesia Specialties business have fixed price agreements covering 100% of its 2017 coal requirements. A hypothetical 10% change in the Corporation’s energy prices in 2017 as compared with 2016, assuming constant volumes, would change 2017 energy expense by $23.1 million. However, the impact would be partially offset by the change in the amount capitalized into inventory standards.

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 Corporation’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 Corporation’s business, financial condition and results of operations. Assuming net sales for the cement product line for full-year 2017 of $380 million to $400 million, a hypothetical 10% change in sales price would impact net sales by $38 million to $40 million.

Item 4. Controls and Procedures

As of March 31, 2017, an evaluation was performed under the supervision and with the participation of the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and the operation of the Corporation’s disclosure controls and procedures. Based on that evaluation, the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Corporation’s disclosure controls and procedures were effective as of March 31, 2017. There were no changes in the Corporation’s internal control over financial reporting during the most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
